It may not be always necessary to approach the treatment of HER2-positive, hormone receptor–negative (HER2+/HR–) early breast cancer with added chemotherapy, survival results of a prospective multicenter randomized trial suggest.

In the ADAPT-HER2+/HR– trial, comparing a de-escalated 12-week neoadjuvant regimen consisting of dual HER2 blockade with trastuzumab (Herceptin) and pertuzumab (Perjeta) with or without weekly paclitaxel, the three-drug regimen was associated with high pathologic complete response(pCR) rates and excellent 5-year survival, irrespective of whether patients received additional chemotherapy, reported Nadia Harbeck, MD, PhD, of the University of Munich.

“Chemotherapy-free regimens are promising in highly sensitive tumors with early response, but future investigation of such chemotherapy-free regimens need to be focused on selected patients, like those with HER2 3+ tumors, non–basal-like tumors, those showing early response to the de-escalated therapy, and those with predictive RNA signatures such as immune signatures,” she said in an oral abstract session during the American Society of Clinical Oncology annual meeting (Abstract 503).
 

Under the WGS umbrella

The ADAPT HER2+/HR– trial (NCT01779206) is one of several conducted by the West German Study Group (WGS) on therapy for intrinsic breast cancer types.

In this study, 134 patients with HER2-positive, estrogen and progesterone receptor–negative tumors with no metastatic disease and good performance status were assigned on a 5:2 basis to neoadjuvant therapy with trastuzumab at a loading dose of 8 mg/kg for the first cycle followed by 6 mg/kg for subsequent cycles every 3 weeks x 4, plus pertuzumab at a loading dose of 840 mg followed by 420 mg every 3 weeks x 4 (92 patients), or to trastuzumab and pertuzumab at the same dose and schedule plus paclitaxel 80 mg/m² once weekly for 12 weeks.

Patients had surgery within 3 weeks of the end of study therapy unless they did not have a histologically confirmed pCR, in which case they went on to receive standard neoadjuvant therapy prior to surgery.

Adjuvant therapy was performed according to national guidelines, although patients with a pCR after 12 weeks of study therapy could be spared from adjuvant chemotherapy at the investigator’s discretion.

Patients underwent biopsy at 3 weeks for therapy for early response assessment, defined as either a Ki67 decrease of at least 30% from baseline, or low cellularity (less than 500 invasive tumor cells).
 

First survival results

The investigators previously reported the primary pCR endpoint from the trial, which showed a rate of 90% after 12 weeks in the three-drug arm, and a “substantial and clinically meaningful” pCR rate of 34% after the trastuzumab plus pertuzumab alone.

At ASCO 2021, Dr. Harbeck reported the first survival data from the trial.

After a median follow-up of 59.9 months, there were no statistically significant differences between trial arms in either overall survival, invasive disease-free survival (iDFS), or distant disease-free survival (dDFS).

The 5-year iDFS rate in the three-drug arm was 98%, compared with 87% for the dual HER2 blockade-only arm, a difference that was not statistically significant.

The 5-year dDFS rates were 98% and 92% respectively. There were only seven dDFS events during follow-up, Dr. Harbeck noted.

There were only six deaths during follow-up, with overall survival rates of 98% in the paclitaxel-containing arm, and 94% in the anti-HER2 antibodies–only arm, a difference of one overall survival event, Dr. Harbeck said.
 

pCR counts

However, patients who did not have pathologic complete responses at the end of first-line de-escalated therapy had worse outcomes, with a 5-year iDFS rate of 82%, compared with 98% for patients who had achieved a pCR. This translated into a hazard ratio for invasive disease in patients with pCRs of 0.14 (P = .011).

This difference occurred despite the study requirement that all patients who did not have pCR after 12 weeks of initial therapy would receive additional chemotherapy.

Looking at the tumor subtype among patients in the paclitaxel-free arm to see whether they could identify predictors of early response, the researchers found a pCR rate of 36.5% among 85 patients with nonbasal tumors, but 0% among 7 patients with basal tumors.

The investigators identified a population of patients whose tumors could be considered nonsensitive to dual HER2 blockade alone: Those with basal tumors, those tumors with low immunohistochemical HER2 expression, and those without an early response to therapy on biopsy 3 weeks into initial therapy. Among 31 of the 92 patients in the dual HER2 arm who met this description, 2 had pCRs, Dr. Harbeck noted.

The 5-year iDFS rate among patients in the dual blockade–only arm with nonsensitive tumors was 79%, compared with 93% for patients with treatment-responsive types, although there were only 13 invasive events total in this arm.

“If we look at the whole trial population, the negative prognostic impact of what we termed nonsensitive tumors was even significant regarding dDFS, with a hazard ratio of about 5,” she said.
 

‘A consistent theme’

Invited discussant Lisa A. Carey, MD, ScM, of the University of North Carolina Lineberger Comprehensive Cancer Center in Chapel Hill, noted that the trial was underpowered for outcomes, but that results nonetheless suggest that patients with strongly HER2-driven tumors might get comparable benefits from less chemotherapy.

“This trial included only hormone receptor–negative, HER2-positive tumors, and these we know are likely to be HER2-enriched in terms of subtype, about three-quarters of them,”she said.

The previously reported pCR rate of 90% in the paclitaxel-containing arm, with 80% of patients requiring no further chemotherapy, resulted in the excellent 5-year iDFS and dDFS in this group, despite the relatively highly clinical stage, with about 60% of patients having clinical stage 2 or higher tumors, and more than 40% being node positive.

The idea that pCR itself can predict which patients could be spared from more intensive chemotherapy “is starting to look like a consistent theme,” she said.

Dr. Carey pointed out that in the KRISTINE trial comparing the combination of trastuzumab emtansine (T-DM1) and pertuzumab with standard chemotherapy in patients with HER2-positive stage I-III breast cancer, although the experimental combination was associated with lower pCR rates and worse event-free survival, rates of iDFS/dDFS were virtually identical for patients in both arms who achieved a pCR.

“So the question is can pCR mean that we can either eliminate additional therapy,” she said, noting that the question is currently being addressed prospectively in two clinical trials, COMPASS-pCR and DECRESCENDO.

Colonoscopies and annual fecal immunochemical tests (FITs), are 2 of the preferred modalities for colorectal cancer (CRC) screening endorsed by the US Preventive Services Task Forces as well as the US Multi-Society Task Force of Colorectal Cancer, which represents the American Gastroenterological Association, American College of Gastroenterology, and the American Society of Gastrointestinal Endoscopy.^1,2 The recommendations include proper patient selection (patients aged 50 - 75 years with a life expectancy of at least 10 years), and a discussion with the patient regarding both options.

Background

It is known that patients with a positive FIT are at an increased risk for CRC. Lee and colleagues found that patients who do not undergo subsequent colonoscopy after a positive FIT have a 1.64 relative risk of death from colon cancer compared with those who undergo follow-up colonoscopy.³ Studies also have shown that longer wait times (10 months vs 1 month) between a positive FIT and colonoscopy also are associated with a higher risk of CRC.⁴ FIT utilize antibodies specific for the globin moiety of human hemoglobin and measure the development of antibody-globin complexes using immunoassay techniques. FIT has largely replaced the fecal occult blood test (FOBT), which depends on the detection of heme in feces through oxidation.

A US Department of Veterans Affairs (VA) study found that a longer time to colonoscopy was associated with a higher risk of neoplasia in veterans with a positive FOBT (odds ratio [OR], 1.10).⁵ It is thus crucial that a positive FOBT or FIT be investigated with follow-up colonoscopy. However, a retrospective study at a single safety-net hospital in San Francisco found that only 55.6% of patients with a positive FIT completed colonoscopy within 1 year.⁶ Importantly, almost half the patients examined in this study lacked documentation of the result of the FIT or counseling regarding the significance of the positive FIT by the patient’s primary care provider who ordered the test. A VA study looked at veterans aged > 70 years at 4 VA medical centers who did not receive a follow-up colonoscopy within 1 year and reported that 26% of patients studied had a documented refusal to undergo colonoscopy.⁷

It also is clear that FOBT is used inappropriately for colon cancer screening in some patients. A 2005 single-center VA study looked at inappropriate fecal occult blood tests and found that 18% of veterans for whom FOBTs were ordered had a severe comorbid illness, 13% had signs or symptoms of gastrointestinal (GI) blood loss, and 7% had a history of colorectal neoplasia or inflammatory bowel disease.⁸ An additional national VA study looked at all veterans aged ≥ 50 years who underwent FOBT or screening colonoscopy between 2009 and 2011 and found 26% to be inappropriate (13.9% of veterans not due for screening, 7.8% with limited life expectancy, and 11% receiving a FOBT when colonoscopy was indicated).⁹

An often-misunderstood additional requirement in utilizing FIT for CRC screening is that negative tests should be repeated annually.² A study from Kaiser Permanente in California found that 75.3 to 86.1% of eligible patients underwent yearly FIT.¹⁰ In this study, programmatic FIT detected 80.4% of all patients with CRC detected within 1 year of testing.

Since most of the VA-specific studies are based on inappropriate or inadequate use of FOBT, we feel it is essential that further data be gained on appropriate and inappropriate testing. The aim of this study is to determine the frequency at which improper FIT occurs because of failure to obtain serial FIT over time with a negative result, failure to follow-up a positive FIT result with a diagnostic colonoscopy, or performance of FIT in veterans undergoing a recent colonoscopy with adequate bowel preparation. This quality assurance study received an institutional review board exemption from the VA Pittsburgh Healthcare System (VAPHS) in Pennsylvania.

Methods

VAPHS has a data repository of all veterans served within the health care system, which was queried for all veterans who underwent a FIT in the system from January 1, 2015 through December 31, 2017 as well as the number and results of FITs during the interval. In addition, the data repository was also queried specifically for veterans who had at least 1 colonoscopy as well as FIT between 2015 and 2017. The ordering location for each FIT also was queried.

We made 3 calculations for this study. First, we measured the rate of a negative initial FIT in 2015 and/or 2016 followed by a second FIT in 2016 and/or 2017 in a random selection of veterans (3% SE, 95% CI). Demographics were compared in an equal random number of veterans who did and did not have a follow up FIT (5% SE, 95% CI of all negative FIT). Second, we measured the rate of completing colonoscopy following a positive FIT in a random selection of veterans (3% SE, 95% SI). Finally, we calculated FITs following a colonoscopy for all veterans.

Using a power analysis with a 3% SE and 95% CI for sample size calculation and accounting for the approximate 50% exclusion rate from the final eligible population of veterans with at least 1 negative FIT, a random sample of 1,742 patient charts with a negative FIT in the interval were then reviewed to determine the frequency with which they underwent multiple FITs in the interval as well as for the presence of exclusionary factors. Because of the large number of veterans involved in this category, a more detailed demographics review was performed of a subset of these patients using a 95% CI and 5% SE. Using a 95% CI and 3% SE, 445 veterans with a positive FIT in the interval were reviewed to determine the frequency at which they underwent a follow-up diagnostic colonoscopy.

Because of a relatively small sample size, all 108 veterans who underwent a colonoscopy followed by a FIT were reviewed to determine the reason for follow-up FIT. In addition, in veterans who then went on to have a subsequent repeat colonoscopy, the examination findings were recorded.

Results

From January 1, 2015 to December 31, 2017, 6,766 FIT, were ordered at VAPHS. Of these, 4,391 unique veterans had at least 1 negative FIT during the period and 709 unique veterans had a positive FIT. There were 832 veterans who had both a FIT and colonoscopy during the study period. Of these, 108 had a colonoscopy with a subsequent FIT (Figure).

Of 1,742 randomly selected veterans with at least 1 negative FIT in the study interval, 870 were eligible for multiple FITs during this period as they were in the appropriate screening age (50-75 years or 85 years based on an assessment of life expectancy by the ordering health care provider [HCP]), did not have exclusionary comorbidities to multiple FIT, were not lost to follow-up, and had at least 1 negative FIT collected from 2015 to 2016 (veterans who only had a FIT in 2017 were excluded from this aim to avoid confounding). Of these 870 veterans, 543 (62.4%) underwent at least 2 FITs during the study period. In a demographic comparison of 110 veterans with 1 FIT and 110 veterans with > 1 FIT, there were no statistically significant differences in demographics (Table 1).

Discussion

In this retrospective study, we found that a large percentage of veterans eligible for colon cancer screening utilizing FIT did not undergo appropriate screening. Almost 40% of veterans in a 3-year interval received only 1 FIT. This seemed to occur due to a combination of patient refusal and inadequate education by HCPs regarding how to screen appropriately for CRC using FIT. This occurred despite a reminder in the VA Computerized Patient Record System regarding CRC screening.

There did not seem to be significant differences in demographics between those who were screened appropriately vs inappropriately. While there was a statistically significant difference in gender between those who had an appropriate FIT following recent colonoscopy (2 of 13 were female) and those who had an inappropriate FIT after recent colonoscopy (1 of 95 was a female), we are uncertain of the significance of this finding given the small number of female veterans in the analysis.

We do believe that the ratio of veterans in our study with a single FIT likely underestimates the true prevalence. To avoid confounding from factors such as inadequate prior follow-up in the study interval, we excluded veterans who underwent FIT only in 2017 for this analysis. As such, a significant percentage of these veterans were actually eligible to be screened throughout the study interval.

In spite of recommendations regarding the need for diagnostic colonoscopy following a positive FIT, we found that more than one-quarter of patients did not undergo colonoscopy. Although this number is an improvement over previously published literature that found almost half of patients at a safety-net hospital did not undergo diagnostic colonoscopy following a positive FIT, this is still clearly suboptimal.⁶

VAPHS has a mandate that all patients with a positive FIT be scheduled for colonoscopy within 30 days, either at VAPHS or in the community. An alert is sent to both ordering HCP regarding the positive FIT as well as to the GI department. In addition to contact from the ordering HCP, all veterans also are contacted by either a physician or nurse practitioner GI provider to provide test results and an explanation of its clinical significance and to facilitate colonoscopy scheduling. If a patient cannot be reached by telephone, the patient is sent a certified letter from the GI department regarding the significance of a positive FIT and instructions for scheduling a colonoscopy.

Limitations

While our study strengths include a relatively large number of veterans and detailed review of individual patient data, it has multiple limitations. As a retrospective chart review-based study, incomplete or inaccurate data are a possibility. It is possible that patients underwent repeat FIT or underwent colonoscopy outside of the VA system and never recorded into the VA records. In addition, there is likely a sampling bias in this study as only veterans who underwent at least 1 FIT in the interval were included. These patients may be different from those who choose to undergo colonoscopy for CRC screening or from those who do not undergo screening at all.

Conclusions

A large percentage of patients underwent improper FIT at a tertiary referral academic VA medical center. Additional education and systems interventions are necessary to improve both provider and patient adherence to appropriate CRC screening. For example, one measure may include providing HCPs with a list of their patients not up-to-date with CRC screening that was shown to increase patient participation in FIT screening compared with patients who received usual care in a 2017 study.¹² In addition, a 2018 study showed that a digital health intervention that allows patients to self-order tests (eg, on an iPad) can increase CRC screening rates.¹³

A 2005 single-center VA study looked at inappropriate fecal occult blood tests and found that 18% of veterans for whom FOBTs were ordered had a severe comorbid illness, 13% had signs or symptoms of gastrointestinal (GI) blood loss, and 7% had a history of colorectal neoplasia or inflammatory bowel disease.⁸ An additional national VA study looked at all veterans aged ≥ 50 years who underwent FOBT or screening colonoscopy between 2009 and 2011 and found 26% to be inappropriate (13.9% of veterans not due for screening, 7.8% with limited life expectancy, and 11% receiving a FOBT when colonoscopy was indicated).⁹

An often-misunderstood additional requirement in utilizing FIT for CRC screening is that negative tests should be repeated annually.² A study from Kaiser Permanente in California found that 75.3 to 86.1% of eligible patients underwent yearly FIT.¹⁰ In this study, programmatic FIT detected 80.4% of all patients with CRC detected within 1 year of testing.

Since most of the VA-specific studies are based on inappropriate or inadequate use of FOBT, we feel it is essential that further data be gained on appropriate and inappropriate testing. The aim of this study is to determine the frequency at which improper FIT occurs because of failure to obtain serial FIT over time with a negative result, failure to follow-up a positive FIT result with a diagnostic colonoscopy, or performance of FIT in veterans undergoing a recent colonoscopy with adequate bowel preparation. This quality assurance study received an institutional review board exemption from the VA Pittsburgh Healthcare System (VAPHS) in Pennsylvania.

Methods

VAPHS has a data repository of all veterans served within the health care system, which was queried for all veterans who underwent a FIT in the system from January 1, 2015 through December 31, 2017 as well as the number and results of FITs during the interval. In addition, the data repository was also queried specifically for veterans who had at least 1 colonoscopy as well as FIT between 2015 and 2017. The ordering location for each FIT also was queried.

We made 3 calculations for this study. First, we measured the rate of a negative initial FIT in 2015 and/or 2016 followed by a second FIT in 2016 and/or 2017 in a random selection of veterans (3% SE, 95% CI). Demographics were compared in an equal random number of veterans who did and did not have a follow up FIT (5% SE, 95% CI of all negative FIT). Second, we measured the rate of completing colonoscopy following a positive FIT in a random selection of veterans (3% SE, 95% SI). Finally, we calculated FITs following a colonoscopy for all veterans.

Using a power analysis with a 3% SE and 95% CI for sample size calculation and accounting for the approximate 50% exclusion rate from the final eligible population of veterans with at least 1 negative FIT, a random sample of 1,742 patient charts with a negative FIT in the interval were then reviewed to determine the frequency with which they underwent multiple FITs in the interval as well as for the presence of exclusionary factors. Because of the large number of veterans involved in this category, a more detailed demographics review was performed of a subset of these patients using a 95% CI and 5% SE. Using a 95% CI and 3% SE, 445 veterans with a positive FIT in the interval were reviewed to determine the frequency at which they underwent a follow-up diagnostic colonoscopy.

Because of a relatively small sample size, all 108 veterans who underwent a colonoscopy followed by a FIT were reviewed to determine the reason for follow-up FIT. In addition, in veterans who then went on to have a subsequent repeat colonoscopy, the examination findings were recorded.

Results

From January 1, 2015 to December 31, 2017, 6,766 FIT, were ordered at VAPHS. Of these, 4,391 unique veterans had at least 1 negative FIT during the period and 709 unique veterans had a positive FIT. There were 832 veterans who had both a FIT and colonoscopy during the study period. Of these, 108 had a colonoscopy with a subsequent FIT (Figure).

Of 1,742 randomly selected veterans with at least 1 negative FIT in the study interval, 870 were eligible for multiple FITs during this period as they were in the appropriate screening age (50-75 years or 85 years based on an assessment of life expectancy by the ordering health care provider [HCP]), did not have exclusionary comorbidities to multiple FIT, were not lost to follow-up, and had at least 1 negative FIT collected from 2015 to 2016 (veterans who only had a FIT in 2017 were excluded from this aim to avoid confounding). Of these 870 veterans, 543 (62.4%) underwent at least 2 FITs during the study period. In a demographic comparison of 110 veterans with 1 FIT and 110 veterans with > 1 FIT, there were no statistically significant differences in demographics (Table 1).

Discussion

In this retrospective study, we found that a large percentage of veterans eligible for colon cancer screening utilizing FIT did not undergo appropriate screening. Almost 40% of veterans in a 3-year interval received only 1 FIT. This seemed to occur due to a combination of patient refusal and inadequate education by HCPs regarding how to screen appropriately for CRC using FIT. This occurred despite a reminder in the VA Computerized Patient Record System regarding CRC screening.

There did not seem to be significant differences in demographics between those who were screened appropriately vs inappropriately. While there was a statistically significant difference in gender between those who had an appropriate FIT following recent colonoscopy (2 of 13 were female) and those who had an inappropriate FIT after recent colonoscopy (1 of 95 was a female), we are uncertain of the significance of this finding given the small number of female veterans in the analysis.

We do believe that the ratio of veterans in our study with a single FIT likely underestimates the true prevalence. To avoid confounding from factors such as inadequate prior follow-up in the study interval, we excluded veterans who underwent FIT only in 2017 for this analysis. As such, a significant percentage of these veterans were actually eligible to be screened throughout the study interval.

In spite of recommendations regarding the need for diagnostic colonoscopy following a positive FIT, we found that more than one-quarter of patients did not undergo colonoscopy. Although this number is an improvement over previously published literature that found almost half of patients at a safety-net hospital did not undergo diagnostic colonoscopy following a positive FIT, this is still clearly suboptimal.⁶

VAPHS has a mandate that all patients with a positive FIT be scheduled for colonoscopy within 30 days, either at VAPHS or in the community. An alert is sent to both ordering HCP regarding the positive FIT as well as to the GI department. In addition to contact from the ordering HCP, all veterans also are contacted by either a physician or nurse practitioner GI provider to provide test results and an explanation of its clinical significance and to facilitate colonoscopy scheduling. If a patient cannot be reached by telephone, the patient is sent a certified letter from the GI department regarding the significance of a positive FIT and instructions for scheduling a colonoscopy.

Limitations

While our study strengths include a relatively large number of veterans and detailed review of individual patient data, it has multiple limitations. As a retrospective chart review-based study, incomplete or inaccurate data are a possibility. It is possible that patients underwent repeat FIT or underwent colonoscopy outside of the VA system and never recorded into the VA records. In addition, there is likely a sampling bias in this study as only veterans who underwent at least 1 FIT in the interval were included. These patients may be different from those who choose to undergo colonoscopy for CRC screening or from those who do not undergo screening at all.

Conclusions

A large percentage of patients underwent improper FIT at a tertiary referral academic VA medical center. Additional education and systems interventions are necessary to improve both provider and patient adherence to appropriate CRC screening. For example, one measure may include providing HCPs with a list of their patients not up-to-date with CRC screening that was shown to increase patient participation in FIT screening compared with patients who received usual care in a 2017 study.¹² In addition, a 2018 study showed that a digital health intervention that allows patients to self-order tests (eg, on an iPad) can increase CRC screening rates.¹³

Colonoscopies and annual fecal immunochemical tests (FITs), are 2 of the preferred modalities for colorectal cancer (CRC) screening endorsed by the US Preventive Services Task Forces as well as the US Multi-Society Task Force of Colorectal Cancer, which represents the American Gastroenterological Association, American College of Gastroenterology, and the American Society of Gastrointestinal Endoscopy.^1,2 The recommendations include proper patient selection (patients aged 50 - 75 years with a life expectancy of at least 10 years), and a discussion with the patient regarding both options.

Background

It is known that patients with a positive FIT are at an increased risk for CRC. Lee and colleagues found that patients who do not undergo subsequent colonoscopy after a positive FIT have a 1.64 relative risk of death from colon cancer compared with those who undergo follow-up colonoscopy.³ Studies also have shown that longer wait times (10 months vs 1 month) between a positive FIT and colonoscopy also are associated with a higher risk of CRC.⁴ FIT utilize antibodies specific for the globin moiety of human hemoglobin and measure the development of antibody-globin complexes using immunoassay techniques. FIT has largely replaced the fecal occult blood test (FOBT), which depends on the detection of heme in feces through oxidation.

A US Department of Veterans Affairs (VA) study found that a longer time to colonoscopy was associated with a higher risk of neoplasia in veterans with a positive FOBT (odds ratio [OR], 1.10).⁵ It is thus crucial that a positive FOBT or FIT be investigated with follow-up colonoscopy. However, a retrospective study at a single safety-net hospital in San Francisco found that only 55.6% of patients with a positive FIT completed colonoscopy within 1 year.⁶ Importantly, almost half the patients examined in this study lacked documentation of the result of the FIT or counseling regarding the significance of the positive FIT by the patient’s primary care provider who ordered the test. A VA study looked at veterans aged > 70 years at 4 VA medical centers who did not receive a follow-up colonoscopy within 1 year and reported that 26% of patients studied had a documented refusal to undergo colonoscopy.⁷

It also is clear that FOBT is used inappropriately for colon cancer screening in some patients. A 2005 single-center VA study looked at inappropriate fecal occult blood tests and found that 18% of veterans for whom FOBTs were ordered had a severe comorbid illness, 13% had signs or symptoms of gastrointestinal (GI) blood loss, and 7% had a history of colorectal neoplasia or inflammatory bowel disease.⁸ An additional national VA study looked at all veterans aged ≥ 50 years who underwent FOBT or screening colonoscopy between 2009 and 2011 and found 26% to be inappropriate (13.9% of veterans not due for screening, 7.8% with limited life expectancy, and 11% receiving a FOBT when colonoscopy was indicated).⁹

The proportion of Americans who’ve experienced two or more sunburns in the past year rose significantly during a recent 10-year period, for reasons that are unclear, Nicole L. Bolick, MD, reported at the virtual annual meeting of the American Academy of Dermatology.

On the plus side, utilization of indoor tanning plunged in the United States during the same period, a statistic worth celebrating as a public health and legislative success, noted Dr. Bolick, who was at the Harvard T.H. Chan School of Public Health, Boston, when she conducted her study and is now at East Carolina University, Greenville, N.C.

More good news: Her analysis of data from 67,471 nationally representative participants in the Centers for Disease Control and Prevention’s National Health Information Survey for the years 2005, 2010, and 2015 also demonstrated that the public’s adoption of several key skin cancer prevention behaviors is on the rise, although she added that rates clearly remain suboptimal.

For example, the proportion of Americans who practice sun avoidance climbed from 31.7% in 2005 to 35.5% in 2010, and 36.8% in 2015 in a multivariate logistic regression analysis adjusted for demographics, alcohol use, location, smoking status, education level, health insurance, and family and personal history of skin cancer.

Similarly, the use of sunscreen always or most of the time when outdoors for more than 1 hour on a warm, sunny day rose from an adjusted 31.5% in 2005 to 33.1% in 2010 and to 34.3% in 2015.

Also, sun protective clothing – long pants, hats, and/or long-sleeved shirts – was utilized always or most of the time by 35.9% of respondents in 2005, 38.4% in 2010, and 37.2% in 2015.

In 2005, 19% of Americans reported having a lifetime history of a physician-performed full body skin examination. The prevalence of this secondary skin cancer prevention measure rose to 22.4% in 2010 and remained the same in 2015.

In the 2005 national survey, 14.1% of respondents reported engaging in indoor tanning within the past year. This figure dropped to 6.2% in 2010 and fell further to 4.1% in 2015.

A history of two or more sunburns within the past year was reported by 18.2% of subjects in 2005, by 21.1% in 2010, and by 19.9% in 2015. It’s unclear whether this unwelcome phenomenon is due to inadequate use of sun protection or increased awareness of the link between sun exposure and skin cancer, with a resultant increase in reporting of sunburns. The influence of climate change is another possible explanation worthy of further study, according to Dr. Bolick.

She reported having no financial conflicts regarding her study, conducted free of commercial support.

Rituximab is a genetically engineered chimeric immunoglobulin G1 monoclonal antibody. It functions by binding to the CD20 antigen on the surface of B-cell lymphocytes, leading to complement-dependent cytotoxicity and antibody-dependent cellular cytotoxicity.¹ The US Food and Drug Administration approved this therapy to treat patients with B-cell non-Hodgkin lymphoma and chronic lymphocytic leukemia, along with other nonmalignant indications, including pemphigus vulgaris and rheumatoid arthritis (RA). Historically, a significant amount of time and labor on behalf of medical personnel has been required to administer rituximab according to the original manufacturer’s labeling due to the boxed warning associated with infusion-related reactions (IRRs).²

Originally, the elongated infusion times that were recommended for rituximab were largely due to the perceived risk of serious infusion-related adverse drug reactions. Slower infusion times should reduce the risk of a reaction and are considered to be a good option for those patients who are at a high risk of having a severe IRRs to rituximab. Examples of high-risk patients from previous studies include those with significant cardiovascular disease, a circulating lymphocyte count ≤ 5,000/µL at the start of infusion, and those who have previously had a reaction to rituximab.^3-5 In appropriate patients, research has shown a decreasing incidence of all-grade IRRs for patients who are prescribed rituximab as they receive more doses of the drug.^2,6 The ability to identify suitable patients for 90-minute infusions of rituximab and the prospect of better health system resource utilization has led investigators to study the effects of shortened infusion times.

The RATE trial addressed this subject with a phase 3 safety study on the effects of a 90-minute rituximab infusion for patients with previously untreated diffuse large B-cell and follicular lymphoma.³ The patients in this study received their first dose of rituximab using the traditional infusion approach. If it was well-tolerated, they received subsequent rituximab infusions using a 90-minute protocol. Only 1.1% of patients who had previously received a rituximab infusion developed a grade 3 or 4 IRR when receiving a faster infusion of the drug for the first time.³ This result led to the addition of instructions for a 90-minute infusion to the package insert.²

In contrast to the RATE trial, the RATE-RA trial evaluated the incidence of IRRs in patients who received rituximab for nonmalignant indications. This study assessed patients with RA receiving rituximab for > 120 minutes. The authors reported 0.6% of the patients in the study developed a grade 3 or 4 IRR associated with the first 120-minute infusion of the medication.⁵ The researchers concluded that rituximab can be administered at a faster rate during second and subsequent infusions in patients who have been shown to tolerate traditional infusions without increasing the risk or severity of IRRs.⁵

The US Department of Veterans Affairs (VA) Richard L. Roudebush VA Medical Center (RLRVAMC) in Indianapolis, Indiana, uses traditional directions for the infusion of rituximab due to perceived tolerability and safety concerns specifically in a veteran population—even while other VA medical centers have implemented shortened infusion protocols. This also is despite the fact that available research shows rapid infusions of the drug are well tolerated in a variety of community settings.^7,8 Anticipated benefits of implementing a protocol include savings in chair time at the institution’s infusion clinic along with increased nursing and patient satisfaction. This project was conducted to prepare, implement, and assess the safety of a 90-minute rituximab protocol at the RLRVAMC.

Methods

Proactive measures were required before and during the implementation of the 90-minute protocol to ensure patient safety and staff satisfaction. Updates to the RLRVAMC policy for the management of medical emergencies within the infusion center were reviewed and approved by the acute care committee and nursing leadership. A protocol was developed to identify eligible patients, outline the hypersensitivity protocol, instruct pharmacy personnel on admixture preparation, and provide a titration schedule based on dose. Order sets also were created to assist health care providers (HCPs) with the prescribing of rituximab for nonantineoplastic indications. Educational materials were crafted to assist with order verification, product preparation, labeling, and programming of infusion pumps. Live education was provided for physicians, pharmacists, and nurses to ensure smooth implementation of the protocol and appropriate management of medical emergencies based on the updated policy.

Study Design

Nursing staff in the infusion clinic were surveyed once before a live education session and again after the conclusion of the study. The purpose of the survey was to assess the prior experience and current comfort level of the nursing staff with administering rituximab over 90 minutes. Nurses were asked the following questions: (1) Do you have prior experience administering rituximab via 90-minute infusion; and (2) do you feel comfortable administering rituximab via 90-minute infusion?

A weekly report of patients who received rituximab between November 1, 2018 through April 1, 2019 at the RLRVAMC was generated. HCPs were alerted to eligible patients based on protocol requirements. The HCPs then made the final determination and entered orders accordingly.

This study was a retrospective chart review of all who patients received a rapid infusion of rituximab. Patients who were included if they were aged ≥ 18 years, received rituximab infusions in the RLRVAMC infusion clinic, had an absolute lymphocyte count ≤ 5,000/mm³ at the time of their rapid infusions, had no significant baseline cardiovascular disease or respiratory compromise, and had no prior grade 3 or 4 rituximab IRRs as defined by Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0.⁹ This study was a quality improvement initiative and considered exempt by the institutional review board. All data were deidentified and secured to ensure patient privacy.

The primary endpoint for this study was the incidence of grade 3 or 4 IRRs associated with the rapid infusion of rituximab. Secondary endpoints included the proportion of patients who experienced a grade 3 or 4 infusion reaction, who received proper treatment according to the institution’s hypersensitivity protocol, savings in infusion clinic chair time, and nursing satisfaction with education and implementation of the rapid infusion rituximab protocol.

The following data were collected for all included patients: demographics, lactic acid dehydrogenase level, white blood cell count, and absolute lymphocyte count prior to rituximab infusion, indication for treatment, dose of rituximab for 90-minute infusion, date of infusion, starting time, ending time, number of previous rituximab infusions within the past 3 months, symptoms of infusion reactions during rituximab infusion, and grade of any infusion reactions that occurred.

Estimated savings in infusion clinic chair time was calculated by taking the difference in time between each completed rapid infusion and the estimated amount of time it would have taken for each patient to receive a traditional infusion. The estimated amount of time for traditional infusion was determined by following the institution’s protocol for administering rituximab to patients who previously tolerated their first dose of the drug (eg, 100 mg/h starting rate and increasing by 100 mg/h every 30 minutes to a maximum infusion rate of 400 mg/h). All endpoints were analyzed using descriptive statistics.

Results

Between November 1, 2018 and April 1, 2019, 11 patients received a total of 24 rapid infusions of rituximab. The majority of patients included in the study were older males, and the most common indication for rapid infusion was follicular lymphoma (Table 1).

Primary Endpoint

All patients who received a rapid infusion of rituximab were reviewed in the analysis of the primary and secondary endpoints. Among the 24 rapid infusions of rituximab, 1 infusion was stopped due to the patient experiencing a grade 3 IRR according to criteria from CTCAE Version 5.0. The patient was found to have dysphagia at baseline and experienced severe symptoms in the days following the first infusion that put the patient at high risk for subsequent infusion related concerns. Eligibility criteria for the 90-minute protocol were updated based on these findings. No patient experienced a grade 4 or 5 IRR. The remaining 23 infusions were well tolerated by the patients with no clinically significant events.

Secondary Endpoints

The patient who experienced a grade 3 IRR to rituximab received proper treatment by infusion clinic nurses according to the RLRVAMC hypersensitivity protocol. Patients who received rapid infusions of rituximab had a mean length of infusion of 95.0 minutes. This was in contrast to the mean time of each patient’s previous nonrapid infusion of 134.3 minutes. The difference between the 2 values equated to a savings in infusion clinic chair mean time of 39.3 minutes per patient.

Nurses were asked whether they had prior experience administering rituximab via 90-minute infusion and whether they felt comfortable administering a 90-minute rituximab infusion. Before the live education session, none of the nurses surveyed had prior experience or felt comfortable administering rituximab over 90 minutes. When the nurses were surveyed poststudy, all reported that they were experienced administering rituximab and felt comfortable with the process (Table 2).

Discussion

The infusion of rituximab has been associated with significant challenges related to the time and labor required. Although a vast number of institutions across the country now infuse the medication over an abbreviated time, HCP concerns for patient safety and appropriate use of hypersensitivity protocol in a veteran population delayed implementation at RLRVAMC. The results from this quality improvement initiative highlight the positive impact of the proactive measures that were used to implement the rapid infusion protocol for rituximab on improving HCP prescribing rates, nursing satisfaction, and appropriate management of IRRs.

Rapid infusion saved on average 39.3 minutes per patient in infusion clinic chair time. Each successful rapid infusion of rituximab potentially opened additional time in clinic for ≥ 1 patients to receive an infusion therapy. The RLRVAMC usually operated at maximum capacity, so the ability to accommodate more patients helped decrease hospital admittances for time-sensitive infusions.

The initial criteria used to screen patients to determine whether a rapid infusion of rituximab would be appropriate was based on inclusion and exclusion criteria for past studies on the same subject.^3-5 The incidence of hypersensitivity reactions associated with study participants who received rapid rituximab infusions also resembles past research done on the subject, which is important to note due to prior misconceptions of staff at the institution of a higher risk of reaction in this specific veteran population. One patient with RA experienced a grade 3 IRR in this study. Although this patient met the original inclusion criteria, the patient had baseline dysphagia, and following the first infusion, reported to the emergency department (ED) with symptoms of delayed anaphylaxis. In this case, the order for rapid infusion was placed in advance and the prescriber was unaware of the ED visit. Based on this event, eligibility criteria for 90-minute rituximab infusions were updated to include additional information specifying that candidates for a rapid infusion also may have no baseline airway compromise. This hypersensitivity reaction also highlighted the need for decision support technology to assist HCPs in patient selection as well as empowering nursing and pharmacy staff to identify concerns once they place orders.

Over the course of the study, investigators assisted the HCPs with preparation of orders for the rapid infusion of rituximab for antineoplastic indications. Due to feasibility issues with this practice moving forward, order sets containing rituximab were updated to include a 90-minute option. This created a more standardized process that allowed HCPs to screen potential patients on their own. The expectation is that HCPs will be more likely to order 90-minute infusions for eligible patients in the future with this efficient and safer process.

Limitations

The small sample size in this study was a limitation. Retrospective data related to the management of infusion reactions and length of infusions were collected from nursing notes. The prospective use of a standardized evaluation tool for adverse drug reactions as well as bar code medication administration technology would improve the data available for this study. Additional studies also would be useful to validate the results.

Conclusions

The proactive measures that were used to implement the rapid infusion rituximab protocol improved HCP prescribing rates, nursing satisfaction, and the management of IRRs. Potential time savings with each infusion was significant. This study confirmed appropriateness of rapid administration of rituximab in this veteran population and has increased interest in implementing other rapid infusion protocols. Protocols, education, and order sets are being developed for daratumumab and infliximab.

Rituximab is a genetically engineered chimeric immunoglobulin G1 monoclonal antibody. It functions by binding to the CD20 antigen on the surface of B-cell lymphocytes, leading to complement-dependent cytotoxicity and antibody-dependent cellular cytotoxicity.¹ The US Food and Drug Administration approved this therapy to treat patients with B-cell non-Hodgkin lymphoma and chronic lymphocytic leukemia, along with other nonmalignant indications, including pemphigus vulgaris and rheumatoid arthritis (RA). Historically, a significant amount of time and labor on behalf of medical personnel has been required to administer rituximab according to the original manufacturer’s labeling due to the boxed warning associated with infusion-related reactions (IRRs).²

Originally, the elongated infusion times that were recommended for rituximab were largely due to the perceived risk of serious infusion-related adverse drug reactions. Slower infusion times should reduce the risk of a reaction and are considered to be a good option for those patients who are at a high risk of having a severe IRRs to rituximab. Examples of high-risk patients from previous studies include those with significant cardiovascular disease, a circulating lymphocyte count ≤ 5,000/µL at the start of infusion, and those who have previously had a reaction to rituximab.^3-5 In appropriate patients, research has shown a decreasing incidence of all-grade IRRs for patients who are prescribed rituximab as they receive more doses of the drug.^2,6 The ability to identify suitable patients for 90-minute infusions of rituximab and the prospect of better health system resource utilization has led investigators to study the effects of shortened infusion times.

The RATE trial addressed this subject with a phase 3 safety study on the effects of a 90-minute rituximab infusion for patients with previously untreated diffuse large B-cell and follicular lymphoma.³ The patients in this study received their first dose of rituximab using the traditional infusion approach. If it was well-tolerated, they received subsequent rituximab infusions using a 90-minute protocol. Only 1.1% of patients who had previously received a rituximab infusion developed a grade 3 or 4 IRR when receiving a faster infusion of the drug for the first time.³ This result led to the addition of instructions for a 90-minute infusion to the package insert.²

In contrast to the RATE trial, the RATE-RA trial evaluated the incidence of IRRs in patients who received rituximab for nonmalignant indications. This study assessed patients with RA receiving rituximab for > 120 minutes. The authors reported 0.6% of the patients in the study developed a grade 3 or 4 IRR associated with the first 120-minute infusion of the medication.⁵ The researchers concluded that rituximab can be administered at a faster rate during second and subsequent infusions in patients who have been shown to tolerate traditional infusions without increasing the risk or severity of IRRs.⁵

The US Department of Veterans Affairs (VA) Richard L. Roudebush VA Medical Center (RLRVAMC) in Indianapolis, Indiana, uses traditional directions for the infusion of rituximab due to perceived tolerability and safety concerns specifically in a veteran population—even while other VA medical centers have implemented shortened infusion protocols. This also is despite the fact that available research shows rapid infusions of the drug are well tolerated in a variety of community settings.^7,8 Anticipated benefits of implementing a protocol include savings in chair time at the institution’s infusion clinic along with increased nursing and patient satisfaction. This project was conducted to prepare, implement, and assess the safety of a 90-minute rituximab protocol at the RLRVAMC.

Methods

Proactive measures were required before and during the implementation of the 90-minute protocol to ensure patient safety and staff satisfaction. Updates to the RLRVAMC policy for the management of medical emergencies within the infusion center were reviewed and approved by the acute care committee and nursing leadership. A protocol was developed to identify eligible patients, outline the hypersensitivity protocol, instruct pharmacy personnel on admixture preparation, and provide a titration schedule based on dose. Order sets also were created to assist health care providers (HCPs) with the prescribing of rituximab for nonantineoplastic indications. Educational materials were crafted to assist with order verification, product preparation, labeling, and programming of infusion pumps. Live education was provided for physicians, pharmacists, and nurses to ensure smooth implementation of the protocol and appropriate management of medical emergencies based on the updated policy.

Nursing staff in the infusion clinic were surveyed once before a live education session and again after the conclusion of the study. The purpose of the survey was to assess the prior experience and current comfort level of the nursing staff with administering rituximab over 90 minutes.

The US Food and Drug Administration (FDA) has expanded the indication for the Gardasil-9 (Merck) vaccine to include prevention of oropharyngeal and other head and neck cancers caused by HPV types 16, 18, 31, 33, 45, 52, and 58.

This new indication is approved under the FDA’s accelerated approval program and is based on the vaccine’s effectiveness in preventing HPV-related anogenital disease. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory clinical trial, which is currently underway.

“At Merck, working to help prevent certain HPV-related cancers has been a priority for more than two decades,” Alain Luxembourg, MD, director, clinical research, Merck Research Laboratories, said in a statement. “Today’s approval for the prevention of HPV-related oropharyngeal and other head and neck cancers represents an important step in Merck’s mission to help reduce the number of men and women affected by certain HPV-related cancers.”

This new indication doesn’t affect the current recommendations that are already in place. In 2018, a supplemental application for Gardasil 9 was approved to include women and men aged 27 through 45 years for preventing a variety of cancers including cervical, vulvar, vaginal, and anal cancer as well as genital warts. But cancers of the head and neck were not included.

The original Gardasil vaccine came on the market in 2006, with an indication to prevent certain cancers and diseases caused by HPV types 6, 11, 16, and 18. It is no longer distributed in the United States.

In 2014, the FDA approved Gardasil 9, which extends the vaccine coverage for the initial four HPV types as five additional types (31, 33, 45, 52, and 58), and its initial indication was for use in both men and women between the ages of 9 through 26 years.
 

Head and neck cancers surpass cervical cancer

More than 2 decades ago, researchers first found a connection between HPV and a subset of head and neck cancers (Curr Opin Oncol. 1999;11(3):191-199). The cancers associated with HPV also appeared to have a different biology and disease pattern, as well as a better prognosis, compared with those that were unrelated. HPV is now responsible for the majority of oropharyngeal squamous cell cancers diagnosed in the United States.

A study published last year found that oral HPV infections were occurring with significantly less frequency among sexually active female adolescents who had received the quadrivalent vaccine, as compared with those who were unvaccinated.

These findings provided evidence that HPV vaccination was associated with a reduced frequency of HPV infection in the oral cavity, suggesting that vaccination could decrease the future risk of HPV-associated head and neck cancers.

The omission of head and neck cancers from the initial list of indications for the vaccine is notable because, according to data from the Centers for Disease Control and Prevention (CDC), oropharyngeal cancers are now the most common malignancy caused by HPV, surpassing cervical cancer.
 

Who will benefit?

An estimated 14 million new HPV infections occur every year in the United States, according to the CDC, and about 80% of individuals who are sexually active have been exposed at some point during their lifetime. In most people, however, the virus will clear on its own without causing any illness or symptoms.

In a Medscape videoblog, Sandra Adamson Fryhofer, MD, MACP, FRCP, helped clarify the adult population most likely to benefit from the vaccine. She pointed out that the HPV vaccine doesn’t treat HPV-related disease or help clear infections, and there are currently no clinical antibody tests or titers that can predict immunity.

“Many adults aged 27-45 have already been exposed to HPV early in life,” she said. Those in a long-term mutually monogamous relationship are not likely to get a new HPV infection. Those with multiple prior sex partners are more likely to have already been exposed to vaccine serotypes. For them, the vaccine will be less effective.”

Fryhofer added that individuals who are now at risk for exposure to a new HPV infection from a new sex partner are the ones most likely to benefit from HPV vaccination.
 

Confirmation needed

The FDA’s accelerated approval is contingent on confirmatory data, and Merck opened a clinical trial this past February to evaluate the efficacy, immunogenicity, and safety of the 9-valent HPV vaccine in men 20 to 45 years of age. The phase 3 multicenter randomized trial will have an estimated enrollment of 6000 men.

The US Food and Drug Administration (FDA) has expanded the indication for the Gardasil-9 (Merck) vaccine to include prevention of oropharyngeal and other head and neck cancers caused by HPV types 16, 18, 31, 33, 45, 52, and 58.

This new indication is approved under the FDA’s accelerated approval program and is based on the vaccine’s effectiveness in preventing HPV-related anogenital disease. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory clinical trial, which is currently underway.

“At Merck, working to help prevent certain HPV-related cancers has been a priority for more than two decades,” Alain Luxembourg, MD, director, clinical research, Merck Research Laboratories, said in a statement. “Today’s approval for the prevention of HPV-related oropharyngeal and other head and neck cancers represents an important step in Merck’s mission to help reduce the number of men and women affected by certain HPV-related cancers.”

This new indication doesn’t affect the current recommendations that are already in place. In 2018, a supplemental application for Gardasil 9 was approved to include women and men aged 27 through 45 years for preventing a variety of cancers including cervical, vulvar, vaginal, and anal cancer as well as genital warts. But cancers of the head and neck were not included.

The original Gardasil vaccine came on the market in 2006, with an indication to prevent certain cancers and diseases caused by HPV types 6, 11, 16, and 18. It is no longer distributed in the United States.

In 2014, the FDA approved Gardasil 9, which extends the vaccine coverage for the initial four HPV types as five additional types (31, 33, 45, 52, and 58), and its initial indication was for use in both men and women between the ages of 9 through 26 years.
 

Head and neck cancers surpass cervical cancer

More than 2 decades ago, researchers first found a connection between HPV and a subset of head and neck cancers (Curr Opin Oncol. 1999;11(3):191-199). The cancers associated with HPV also appeared to have a different biology and disease pattern, as well as a better prognosis, compared with those that were unrelated. HPV is now responsible for the majority of oropharyngeal squamous cell cancers diagnosed in the United States.

A study published last year found that oral HPV infections were occurring with significantly less frequency among sexually active female adolescents who had received the quadrivalent vaccine, as compared with those who were unvaccinated.

These findings provided evidence that HPV vaccination was associated with a reduced frequency of HPV infection in the oral cavity, suggesting that vaccination could decrease the future risk of HPV-associated head and neck cancers.

The omission of head and neck cancers from the initial list of indications for the vaccine is notable because, according to data from the Centers for Disease Control and Prevention (CDC), oropharyngeal cancers are now the most common malignancy caused by HPV, surpassing cervical cancer.

The U.S. Surgeon General is calling on all physicians to help patients stop smoking, noting that two-thirds of adult smokers say they want to quit, but only 40% report that their doctor has advised them to stop.

“I’ve got to own this as the nation’s doctor, and our health providers in this room and in this country need to own this stat,” said Surgeon General Jerome Adams, MD, at a press briefing releasing a new report on smoking cessation.

“Smoking is the No. 1 preventable cause of death, disease, and disability in the United States,” he said. “So why are 40% of our health providers out there not advising smokers to quit when they come in?”

In the first U.S. Surgeon General report on smoking cessation in 30 years, the 700-page report suggests smoking cessation-related quality measures that include physician reimbursement would increase treatment.

The evidence also suggests that using electronic health records to prompt clinicians to inquire about smoking would increase cessation treatment.

EHRs could be used to “empower and enable” physicians to advise people to quit, said Dr. Adams. Physicians also need “the education and the confidence to be able to have that conversation, because too many of them look at someone and say: ‘Nope, too hard, too much effort, no, that’s not what they’re here for today,’ ” he said.

However, “simply asking, advising, and referring can be enough to get someone on the pathway to quitting,” Dr. Adams said.
 

34 million still smoke

The new report is the first on the topic released since 1990, and the 34th on tobacco control since the first one was issued in 1964, said Dr. Adams. Since that first report, adult smoking has declined 70%, but some 34 million Americans (14%) still smoke, he said.

In addition, Dr. Adams said that many subpopulations have been left behind, noting: “Cigarette smoking remains highest among LGBTQ adults, people with disabilities or limitations, American Indians and Alaska Natives, and people with mental health conditions or substance use disorders.”

He also noted that 40% of cigarettes are consumed by those with a mental illness or a substance use disorder.

Quitting is beneficial at any age and can add as much as a decade to life expectancy, the report notes. Quitting also reduces the risk of 12 cancers, cuts the risk of chronic obstructive pulmonary disease, and reduces cardiovascular and stroke morbidity and mortality.

Pregnant women who quit also reduce their own morbidity and mortality risk and that of unborn children and infants, the report says.

“We know more about the science of quitting than ever before. We can, and must, do more to ensure that evidence-based cessation treatments are reaching the people that need them,” said Dr. Adams.

Less than one-third of those who have quit have used Food and Drug Administration–approved cessation medications or behavioral counseling, Dr. Adams said.
 

Barriers to care

Despite the existence of five nicotine replacement therapies and two nonnicotine oral medications, and more widespread availability of proven counseling methods – including web- or text-based programs – barriers to access remain.

These include a lack of insurance coverage for comprehensive, evidence-based smoking cessation treatment, which, when offered, increases availability and use.

“These are cost-effective interventions,” said Dr. Adams. “It’s penny wise and pound foolish to not give someone access to what we know works,” he said.

Because of the diversity of e-cigarette products and the variety of ways they are used, coupled with little research, it’s not currently possible to determine whether they are, or are not, useful smoking cessation tools, the report notes.

However, experts who compiled the report found some evidence to suggest that e-cigarettes containing nicotine may be “associated with increased smoking cessation compared with the use of e-cigarettes not containing nicotine.”

Asked whether the report’s conclusions might be interpreted as supportive of e-cigarettes, Dr. Adams said the report focused on smoking cessation, not initiation.

“I’m terribly concerned about the clear data that shows youth are initiating tobacco product use with e-cigarettes,” he said.

The Trump administration’s current proposal to partially restrict sales of some flavored e-cigarettes “reflects the science,” and “a balance between a desire to really make sure that people aren’t initiating with these products, but also a desire to again try to maintain a pathway for adults who want to use these products to quit to use them,” Dr. Adams said.

The focus, said Dr. Adams, should not be on e-cigarettes and whether they do, or do not, work.

“People want to quit,” he said. “We know what works. Not enough of them are getting it, and there are terrible disparities in who is and who is not getting access to effective and evidence-based treatment – that’s the story here.”
