WASHINGTON – The routine practice of holding use of blood-thinning medications at the time of an ultrasound-guided thyroid nodule fine needle aspiration (FNA) biopsy shows no significant safety benefit in preventing the risk of complications such as hematomas or nondiagnostic results; however, experts suggest using individualized decision-making with the practice.

“Our data indicates that there is no need to routinely hold anticoagulation or antiplatelet therapy prior to thyroid nodule FNA biopsy,” first author Michelle Lundholm, MD, of the Cleveland Clinic said in an interview.

“[The practice] impacts neither the safety of the FNA procedure nor the adequacy of the sample,” she said.

The late-breaking research was presented at the annual meeting of the American Thyroid Association.

Key concerns in the use of anticoagulants and/or antiplatelet medications during thyroid nodule FNA biopsy include the increased risk of postprocedural hematoma or nondiagnostic results, with, for instance, one study showing higher rates of nondiagnostic results among patients remaining on aspirin therapy during the FNA biopsy.

However, holding the medically indicated therapies can have risks of its own, including concerns of thrombotic events such as deep vein thrombosis or stroke. However, evidence comparing the risks with each strategy in thyroid nodule FNA is lacking.

To investigate, Dr. Lundholm and colleagues conducted a review of data on 2,945 patients who had undergone a total of 4,741 thyroid nodule FNAs in the Cleveland Clinic’s diverse network of centers between 2010 and 2023. The patients had a mean age of 66.2; 69.6% were female and 75.7% were White.

All patients had an active prescription for an anticoagulant or antiplatelet medication up to 10 days prior to their thyroid nodule FNA biopsy. Specifically, 73.7% were on 81 mg aspirin, 8.5% were on 325 mg aspirin, 7.4% were taking other antiplatelet medication such as clopidogrel or ticagrelor; 7.0% were on warfarin, 8.2% were on a direct oral anticoagulant (DOAC); 6.3% were on heparin products; and 10.3% of patients were on two or more blood-thinning medications.

The results show that, overall, 13.0% (n =  614) of the thyroid nodule FNA biopsies had nondiagnostic results, which is within the average rates in the literature ranging from 6% to 36%, Dr. Lundholm noted.

Blood-thinning medications were held in 20.8% of the FNA biopsies, however, there were no differences in nondiagnostic results between those who had drugs held (12.2%) or who continued on the medications (13.2%; P  = .41).

After multivariate adjustment for age and sex, the lack of significant differences in receiving nondiagnostic results among those who did or did not continue blood thinners was consistent overall (odds ratio, 1.10; P = .38), and in the specific groups of 81 mg aspirin (OR, 1.00; P = .99); 325 mg aspirin or clopidogrel/ticagrelor (OR, 1.50; P = .15); or warfarin, DOAC, or heparin/enoxaparin (OR, 1.27; P = .27).

In terms of hematoma risk, ED records within 48 hours of the FNA showed that such events were rare, with only one hematoma occurring overall, involving a patient who was on 81 mg of aspirin for secondary stroke prevention that was not interrupted for FNA biopsy. The patient was discharged and did not require medical intervention.  

Four other hematomas occurred among patients who were not being treated with blood thinners, with none requiring intervention.

The findings indicate that “hematoma can happen in any patient, but rarely requires intervention,” Dr. Lundholm said.

However, while thrombotic events were also rare, serious events occurred in three patients within 48 hours of the thyroid nodule FNA biopsy when a blood thinner was withheld, including ischemic strokes among two patients who were on a DOAC and 81 mg of aspirin that were withheld, and one MI occurring in a patient on a DOAC that was held for the FNA.

Unlike hematomas, the thrombotic events each had significant long‐term sequelae, Dr. Lundholm noted.

“Having these ischemic strokes and heart attack really led to a change in these patients’ lives,” she said. “While we can never assume that [the events occurred] because the blood-thinner therapy was held, the timing within 48 hours is certainly very suspicious.”

There were no deep vein thrombosis or pulmonary embolism events.
 

Withholding practices vary

In a previous survey of 60 clinicians conducted by Dr. Lundholm and colleagues, wide variation was reported in the rates of withholding antiplatelet or anticoagulant medications prior to thyroid nodule FNA biopsy.

The survey of endocrinologists, interventional radiologists, and ear, nose, and throat providers showed rates of withholding 81 mg of aspirin prior to FNA biopsy of just 13.3%, withholding 325 mg of aspirin, 15%, other antiplatelets, 41.7%, warfarin, 73.3%, DOACs, 43.3%, and heparin, 43.3%.

“We found heterogeneity in withholding patterns even within the same department,” she said. “This is reflective of the fact that evidence is mixed.”

Guidelines on the issue from the Society of Interventional Radiology and the International Society on Thrombosis and Hemostasis recommend that providers consider the balance of the procedure and patient bleeding risk versus the clotting risk, Dr. Lundholm noted.

However, a caveat is that those recommendations are based on pooled data from similar minimal risk procedures, she explained.

“There is a lack of data on bleeding risks for individual interventions like thyroid biopsy, and, as such, there is no specific procedure-related risk determination.”

Meanwhile, Dr. Lundholm said that notable limitations regarding the current research include that the study may not have caught all patient cases that presented with complications to an outside ED.

Furthermore, the study results pertain to the safety of blood thinners in routine use, with key aspects that can influence complication rates, such as provider experience, needle size, and nodule features unavailable for analysis.
 

At MD Anderson, case-by-case

Commenting on the research, Anastasios Maniakas, MD, PhD, of the department of head and neck surgery, division of surgery, University of Texas MD Anderson Cancer Center, Houston, said the study is important, noting that, at his institution, the approach regarding holding blood-thinning medications is generally determined on an individual basis.

“I think this was a good study, but I don’t think it’s practice changing because these decisions may differ on a case-by-case basis,” Dr. Maniakas, who comoderated the session, said in an interview.

“At MD Anderson, we probably have one of the highest volumes in the country for thyroid nodule FNAs, and we do hold blood thinners because we often have to do more significant biopsies, with multiple passages and larger needles to be used,” Dr. Maniakas said.

“If you’re going to use perhaps the smallest possible gauge needle, then I think it is reasonable to not hold blood thinners, but if you’re going to be doing multiple passages and you need to do a core biopsy and use a large needle, then it is wiser to try to hold the medications for a day or 2.

“We haven’t had any complications, but I think there’s still a lot of apprehension to not hold blood thinners,” Dr. Maniakas said. “So, overall, I think the message is that it has to be on a case-by-case basis.”

Dr. Lundholm and Dr. Maniakas reported no relevant financial relationships.

HAMBURG, GERMANY – Once-weekly tirzepatide (Mounjaro, Lilly) added to insulin glargine resulted in greater reductions in hemoglobin A1c along with more weight loss and less hypoglycemia, compared with prandial insulin lispro (Humalog, Sanofi), for patients with inadequately controlled type 2 diabetes, show data from the SURPASS-6 randomized clinical trial.

Tirzepatide led to a statistically and clinically significant reduction in mean A1c, at −2.1%, compared with insulin lispro, at −1.1%, by week 52. It also resulted in a higher percentage of participants meeting an A1c target of less than 7.0%, wrote the researchers, whose study was presented at the annual meeting of the European Association for the Study of Diabetes and was published simultaneously in JAMA.

Also, daily insulin glargine use was substantially lower among participants who received tirzepatide, compared with insulin lispro. Insulin glargine was administered at a dosage 13 IU/day; insulin lispro was administered at a dosage of 62 IU/day. “At the highest dose, some patients stopped their insulin [glargine] in the tirzepatide arm,” said Juan Pablo Frias, MD, medical director and principal investigator of Velocity Clinical Research, Los Angeles, who presented the findings. “We demonstrated clinically meaningful and superior glycemic and body weight control with tirzepatide compared with insulin lispro, while tirzepatide was also associated with less clinically significant hypoglycemia.”

Weight improved for participants who received tirzepatide compared with those who received insulin lispro, at –10 kg and +4 kg respectively. The rate of clinically significant hypoglycemia (blood glucose < 54 mg/dL) or severe hypoglycemia was tenfold lower with tirzepatide, compared with insulin lispro.

The session dedicated to tirzepatide was comoderated by Apostolos Tsapas, MD, professor of medicine and diabetes, Aristotle University, Thessaloniki, Greece, and Konstantinos Toulis, MD, consultant in endocrinology and diabetes, General Military Hospital, Thessaloniki, Greece. Dr. Toulis remarked that, in the chronic disease setting, management and treatment intensification are challenging to integrate, and there are barriers to adoption in routine practice. “This is particularly true when it adds complexity, as in the case of multiple prandial insulin injections on top of basal insulin in suboptimally treated individuals with type 2 diabetes.

“Demonstrating superiority over insulin lispro in terms of the so-called trio of A1c, weight loss, and hypoglycemic events, tirzepatide offers both a simpler to adhere to and a more efficacious treatment intensification option.” He noted that, while long-term safety data are awaited, “this seems to be a definite step forward from any viewpoint, with the possible exception of the taxpayer’s perspective.”

Dr. Tsapas added: “These data further support the very high dual glucose and weight efficacy of tirzepatide and the primary role of incretin-related therapies amongst the injectables for the treatment of type 2 diabetes.”
 

Tirzepatide 5, 10, 15 mg vs. insulin lispro in addition to insulin glargine

The researchers aimed to assess the efficacy and safety of adding once-weekly tirzepatide, compared with thrice-daily prandial insulin lispro, as an adjunctive therapy to insulin glargine for patients with type 2 diabetes that was inadequately controlled with basal insulin.

Tirzepatide activates the body’s receptors for glucose-dependent insulinotropic polypeptide and glucagonlike peptide–1 (GLP-1). The study authors noted that “recent guidelines support adding an injectable incretin-related therapy such as GLP-1 receptor agonist for glycemic control, rather than basal insulin, when oral medications are inadequate.”

The open-label, phase 3b clinical trial drew data from 135 sites across 15 countries and included 1,428 adults with type 2 diabetes who were taking basal insulin. Participants were randomly assigned in a 1:1:1:3 ratio to receive once-weekly subcutaneous injections of tirzepatide (5 mg [n = 243], 10 mg [n = 238], or 15 mg [n = 236]) or prandial thrice-daily insulin lispro (n = 708).

Both arms were well matched. The average age was 60 years, and 60% of participants were women. The average amount of time patients had type 2 diabetes was 14 years; 85% of participants continued taking metformin. The average A1c level was 8.8% at baseline. Patients were categorized as having obesity (average body mass index, 33 kg/m²). The average insulin glargine dose was 46 units, or 0.5 units/kg.

Outcomes included noninferiority of tirzepatide (pooled cohort) compared with insulin lispro, both in addition to insulin glargine; and A1c change from baseline to week 52 (noninferiority margin, 0.3%). Key secondary endpoints included change in body weight and percentage of participants who achieved an A1c target of less than 7.0%.

About 90% of participants who received the study drug completed the study, said Dr. Frias. “Only 0.5% of tirzepatide patients needed rescue therapy, while only 2% of the insulin lispro did.”

Prior to optimization, the average insulin glargine dose was 42 IU/kg; during optimization, it rose to an average of 46 IU/kg. “At 52 weeks, those on basal-bolus insulin found their insulin glargine dose stayed flat while insulin lispro was 62 units,” reported Dr. Frias. “The three tirzepatide doses show a reduction in insulin glargine, such that the pooled dose reached an average of 11 units, while 20% actually came off their basal insulin altogether [pooled tirzepatide].”

Tirzepatide (pooled) led to the recommended A1c target of less than 7.0% for 68% of patients versus 36% of patients in the insulin lispro group.

About 68% of the patients who received tirzepatide (pooled) achieved the recommended A1c target of less than 7.0% versus 36% of patients in the insulin lispro group.

“Individual tirzepatide doses and pooled doses showed significant reduction in A1c and up to a 2.5% reduction,” Dr. Frias added. “Normoglycemia was obtained by a greater proportion of patients on tirzepatide doses versus basal-bolus insulin – one-third in the 15-mg tirzepatide dose.”
 

Body weight reduction of 10% or more with tirzepatide

Further, at week 52, weight loss of 5% or more was achieved by 75.4% of participants in the pooled tirzepatide group, compared with 6.3% in the prandial lispro group. The weight loss was accompanied by clinically relevant improvements in cardiometabolic parameters.

In an exploratory analysis, weight loss of 10% or more was achieved by a mean of 48.9% of pooled tirzepatide-treated participants at week 52, compared with 2% of those taking insulin lispro, said Dr. Frias.

“It is possible that the body weight loss induced by tirzepatide therapy and its reported effect in reducing liver fat content may have led to an improvement in insulin sensitivity and decreased insulin requirements,” wrote the researchers in their article.

Hypoglycemia risk and the weight gain observed with complex insulin regimens that include prandial insulin have been main limitations to optimally up-titrate insulin therapy in clinical practice, wrote the authors.

Dr. Frias noted that, in this study, 48% of patients who received insulin lispro experienced clinically significant hypoglycemia, while only 10% of patients in the tirzepatide arms did. “This was 0.4 episodes per patient-year versus 4.4 in tirzepatide and insulin lispro respectively.”

There were more reports of adverse events among the tirzepatide groups than the insulin lispro group. “Typically, with tirzepatide, the commonest adverse events were GI in origin and were mild to moderate.” Rates were 14%-26% for nausea, 11%-15% for diarrhea, and 5%-13% for vomiting.

The study was sponsored by Eli Lilly. Dr. Frias has received grants from Eli Lilly paid to his institution during the conduct of the study and grants, personal fees, or nonfinancial support from Boehringer Ingelheim, Pfizer, Merck, Altimmune, 89BIO, Akero, Carmot Therapeutics, Intercept, Janssen, Madrigal, Novartis, Eli Lilly, Sanofi, and Novo Nordisk outside the submitted work. Dr. Toulis and Dr. Tsapas declared no relevant disclosures.

Dr. Tsapas added: “These data further support the very high dual glucose and weight efficacy of tirzepatide and the primary role of incretin-related therapies amongst the injectables for the treatment of type 2 diabetes.”
 

Tirzepatide 5, 10, 15 mg vs. insulin lispro in addition to insulin glargine

The researchers aimed to assess the efficacy and safety of adding once-weekly tirzepatide, compared with thrice-daily prandial insulin lispro, as an adjunctive therapy to insulin glargine for patients with type 2 diabetes that was inadequately controlled with basal insulin.

Tirzepatide activates the body’s receptors for glucose-dependent insulinotropic polypeptide and glucagonlike peptide–1 (GLP-1). The study authors noted that “recent guidelines support adding an injectable incretin-related therapy such as GLP-1 receptor agonist for glycemic control, rather than basal insulin, when oral medications are inadequate.”

The open-label, phase 3b clinical trial drew data from 135 sites across 15 countries and included 1,428 adults with type 2 diabetes who were taking basal insulin. Participants were randomly assigned in a 1:1:1:3 ratio to receive once-weekly subcutaneous injections of tirzepatide (5 mg [n = 243], 10 mg [n = 238], or 15 mg [n = 236]) or prandial thrice-daily insulin lispro (n = 708).

Both arms were well matched. The average age was 60 years, and 60% of participants were women. The average amount of time patients had type 2 diabetes was 14 years; 85% of participants continued taking metformin. The average A1c level was 8.8% at baseline. Patients were categorized as having obesity (average body mass index, 33 kg/m²). The average insulin glargine dose was 46 units, or 0.5 units/kg.

Outcomes included noninferiority of tirzepatide (pooled cohort) compared with insulin lispro, both in addition to insulin glargine; and A1c change from baseline to week 52 (noninferiority margin, 0.3%). Key secondary endpoints included change in body weight and percentage of participants who achieved an A1c target of less than 7.0%.

About 90% of participants who received the study drug completed the study, said Dr. Frias. “Only 0.5% of tirzepatide patients needed rescue therapy, while only 2% of the insulin lispro did.”

Prior to optimization, the average insulin glargine dose was 42 IU/kg; during optimization, it rose to an average of 46 IU/kg. “At 52 weeks, those on basal-bolus insulin found their insulin glargine dose stayed flat while insulin lispro was 62 units,” reported Dr. Frias. “The three tirzepatide doses show a reduction in insulin glargine, such that the pooled dose reached an average of 11 units, while 20% actually came off their basal insulin altogether [pooled tirzepatide].”

Tirzepatide (pooled) led to the recommended A1c target of less than 7.0% for 68% of patients versus 36% of patients in the insulin lispro group.

About 68% of the patients who received tirzepatide (pooled) achieved the recommended A1c target of less than 7.0% versus 36% of patients in the insulin lispro group.

“Individual tirzepatide doses and pooled doses showed significant reduction in A1c and up to a 2.5% reduction,” Dr. Frias added. “Normoglycemia was obtained by a greater proportion of patients on tirzepatide doses versus basal-bolus insulin – one-third in the 15-mg tirzepatide dose.”
 

Body weight reduction of 10% or more with tirzepatide

Further, at week 52, weight loss of 5% or more was achieved by 75.4% of participants in the pooled tirzepatide group, compared with 6.3% in the prandial lispro group. The weight loss was accompanied by clinically relevant improvements in cardiometabolic parameters.

In an exploratory analysis, weight loss of 10% or more was achieved by a mean of 48.9% of pooled tirzepatide-treated participants at week 52, compared with 2% of those taking insulin lispro, said Dr. Frias.

“It is possible that the body weight loss induced by tirzepatide therapy and its reported effect in reducing liver fat content may have led to an improvement in insulin sensitivity and decreased insulin requirements,” wrote the researchers in their article.

Hypoglycemia risk and the weight gain observed with complex insulin regimens that include prandial insulin have been main limitations to optimally up-titrate insulin therapy in clinical practice, wrote the authors.

Dr. Frias noted that, in this study, 48% of patients who received insulin lispro experienced clinically significant hypoglycemia, while only 10% of patients in the tirzepatide arms did. “This was 0.4 episodes per patient-year versus 4.4 in tirzepatide and insulin lispro respectively.”

There were more reports of adverse events among the tirzepatide groups than the insulin lispro group. “Typically, with tirzepatide, the commonest adverse events were GI in origin and were mild to moderate.” Rates were 14%-26% for nausea, 11%-15% for diarrhea, and 5%-13% for vomiting.

The study was sponsored by Eli Lilly. Dr. Frias has received grants from Eli Lilly paid to his institution during the conduct of the study and grants, personal fees, or nonfinancial support from Boehringer Ingelheim, Pfizer, Merck, Altimmune, 89BIO, Akero, Carmot Therapeutics, Intercept, Janssen, Madrigal, Novartis, Eli Lilly, Sanofi, and Novo Nordisk outside the submitted work. Dr. Toulis and Dr. Tsapas declared no relevant disclosures.

HAMBURG, GERMANY – Once-weekly tirzepatide (Mounjaro, Lilly) added to insulin glargine resulted in greater reductions in hemoglobin A1c along with more weight loss and less hypoglycemia, compared with prandial insulin lispro (Humalog, Sanofi), for patients with inadequately controlled type 2 diabetes, show data from the SURPASS-6 randomized clinical trial.

Tirzepatide led to a statistically and clinically significant reduction in mean A1c, at −2.1%, compared with insulin lispro, at −1.1%, by week 52. It also resulted in a higher percentage of participants meeting an A1c target of less than 7.0%, wrote the researchers, whose study was presented at the annual meeting of the European Association for the Study of Diabetes and was published simultaneously in JAMA.

Also, daily insulin glargine use was substantially lower among participants who received tirzepatide, compared with insulin lispro. Insulin glargine was administered at a dosage 13 IU/day; insulin lispro was administered at a dosage of 62 IU/day. “At the highest dose, some patients stopped their insulin [glargine] in the tirzepatide arm,” said Juan Pablo Frias, MD, medical director and principal investigator of Velocity Clinical Research, Los Angeles, who presented the findings. “We demonstrated clinically meaningful and superior glycemic and body weight control with tirzepatide compared with insulin lispro, while tirzepatide was also associated with less clinically significant hypoglycemia.”

Weight improved for participants who received tirzepatide compared with those who received insulin lispro, at –10 kg and +4 kg respectively. The rate of clinically significant hypoglycemia (blood glucose < 54 mg/dL) or severe hypoglycemia was tenfold lower with tirzepatide, compared with insulin lispro.

The session dedicated to tirzepatide was comoderated by Apostolos Tsapas, MD, professor of medicine and diabetes, Aristotle University, Thessaloniki, Greece, and Konstantinos Toulis, MD, consultant in endocrinology and diabetes, General Military Hospital, Thessaloniki, Greece. Dr. Toulis remarked that, in the chronic disease setting, management and treatment intensification are challenging to integrate, and there are barriers to adoption in routine practice. “This is particularly true when it adds complexity, as in the case of multiple prandial insulin injections on top of basal insulin in suboptimally treated individuals with type 2 diabetes.

SAN DIEGO – Children and young adults with low-risk relapsed or refractory classic Hodgkin lymphoma may be able to skip autologous stem cell transplant.

Patients who received second-line chemoimmunotherapy with nivolumab-brentuximab vedotin, with or without bendamustine, and proceeded to involved-site radiation appeared to have similar survival outcomes to those who received the chemoimmunotherapy combination plus the current second-line standard of care, which includes high-dose therapy and autologous stem cell transplant.

Among 28 patients with low-risk relapsed or refractory Hodgkin lymphoma followed for a median of 32 months, 3-year event-free survival without autologous stem cell transplant was 86.9% and 3-year progression-free survival was 95%, reported Brad Hoppe, MD, MPH, from the Mayo Clinic in Jacksonville, Fla. In contrast, 1-year progression-free survival was 91% among the 44 standard-risk patients who received high-dose therapy and autologous stem cell transplant, according to results of a trial the investigators published online in Blood in late 2022.

The latest results from the phase 2 CheckMate 744 trial were reported at the annual meeting of the American Society of Radiation Oncology.

“The findings suggest that children, adolescents, and young adults with low-risk relapsed classic Hodgkin lymphoma can be salvaged with low-toxicity chemoimmunotherapy and may not require high-dose therapy and transplant for a cure,” Dr. Hoppe said in an oral abstract session.

Andrea Ng, MD, MPH, a radiation oncologist who specializes in treating patients with Hodgkin lymphoma and other hematologic malignancies, said that, while the number of patients in the study was small and the follow-up too short, this option is “certainly something that’s very promising for the future.”

“The use of transplant in relapsed patients, which we have been doing for decades, is based on two very old, small, randomized studies,” said Dr. Ng, from the Dana-Farber Cancer Institute in Boston, who moderated the session.

“So, do we really need to transplant everybody? In the back of our minds, we think that we may be overtreating some patients,” she said.

Several small, retrospective studies exploring treatment with conventional chemotherapy with or without radiation therapy and without transplant in patients with relapsed or refractory Hodgkin lymphoma have demonstrated only modest results.

The CheckMate 744 trial, however, was designed to examine a risk-adapted and response-adapted approach to treating children, adolescents, and young adults with relapsed or refractory classic Hodgkin lymphoma within the setting of modern immunotherapy and targeted therapy. This approach was developed jointly by investigators with the Children’s Oncology Group and Euronet.

In the nonrandomized trial, patients were stratified into low-risk or standard-risk disease categories based on an algorithm that included factors at the time of initial diagnosis and relapse.

Patients were considered low-risk for relapse in three scenarios: (1) if they had initial stage IA or IIA disease that relapsed at least 1 year after the end of therapy; (2) if they had initial stage IA or IIA disease that relapsed between 3 and 12 months from the end of therapy but had received no more than three cycles of chemotherapy and no radiation therapy; or (3) if they had initial stage IB, IIB, or IIIA disease that relapsed more than 12 months after the end of first-line therapy.

To be included in the low-risk category, patients also had to be free of B symptoms or extranodal disease, free of relapse in prior radiation therapy fields, and have no more than four sites of lymphoma. 

Low-risk patients were treated with a combination of nivolumab and brentuximab vedotin, which could be followed by additional brentuximab vedotin and bendamustine for those with a suboptimal response. Patients who achieved complete molecular remission after induction went on to consolidation therapy with involved-site radiation at a total dose of 30 Gy.

Patients considered standard-risk for relapse received the same nivolumab-brentuximab vedotin combination, with or without bendamustine, and then went on to high-dose therapy and autologous stem cell transplant.

In other results for the previously mentioned study published in Blood, the 44 standard-risk patients who received high-dose therapy and autologous stem cell transplant had an objective response rate of 95% – 86% of patients achieved complete molecular remission, and 9% achieved partial molecular remission.

At ASTRO, Dr. Hoppe reported results for the 28 patients with low-risk disease. One patient discontinued nivolumab/brentuximab vedotin after two cycles because of skin toxicity and was lost to follow-up. Of the remaining 27 patients, 21 had complete molecular remission after four cycles of the combination, and these patients went on to an additional two cycles of the combination, with 19 of 21 receiving involved-site radiation consolidation. 

Six patients who had either a partial molecular remission or no response were given two additional cycles of brentuximab vedotin plus bendamustine. Of this group, three went on to complete molecular remission and received involved-site radiation consolidation on protocol. The remaining three patients who did not experience complete molecular remission received involved-site radiation off protocol.

The rate of complete molecular remission after four cycles of induction was 82.1%, and the rate of partial molecular remission was 14.3%, for an objective response rate of 96.4%. The respective response rates with the addition of two cycles of brentuximab vedotin and bendamustine were 92.9% and 7.1%, for an objective response rate of 100%, Dr. Hoppe reported.

Overall, at a median follow-up of 32 months, the 3-year event-free survival rate without transplant was 86.9%, and the 3-year progression-free survival rate was 95%.

Treatment-related adverse events of any grade occurred in 22 patients (78.6%) after induction, with 7 of those events (25%) being grade 3 or 4 in severity. Grade 3 or 4 events consisted of skin and subcutaneous tissue disorders in 3 patients, elevated liver function tests in 3 patients, and blood and lymphatic system disorders in 1 patient.

There were no new toxicities detected within 100 days of treatment.

“The results that Dr. Hoppe showed us are really, really good,” Dr. Ng said. And “the volume of treatment is pretty tiny, so I think we can safely say that long-term toxicities are very, very minimal.”

The study was supported by Bristol-Myers Squibb in collaboration with Seagen, Euronet-Paediatric Hodgkin Lymphoma, and the Children’s Oncology Group. Dr. Hoppe reported serving on a scientific advisory committee for Merck. Dr. Ng reported having no relevant conflicts of interest.

“The results that Dr. Hoppe showed us are really, really good,” Dr. Ng said. And “the volume of treatment is pretty tiny, so I think we can safely say that long-term toxicities are very, very minimal.”

The study was supported by Bristol-Myers Squibb in collaboration with Seagen, Euronet-Paediatric Hodgkin Lymphoma, and the Children’s Oncology Group. Dr. Hoppe reported serving on a scientific advisory committee for Merck. Dr. Ng reported having no relevant conflicts of interest.

SAN DIEGO – Engaging in sexual intercourse and vaginal dilation appears to lower the risk of stenosis, the narrowing/shortening of the vaginal canal, after chemoradiation treatment for cervical cancer, a new 5-year prospective study reports.

Findings from the EMBRACE study were presented at the annual American Society for Radiation Oncology (ASTRO) meeting and included 882 women with locally advanced cervical cancer. Of those, 565 women reported regular vaginal dilation and/or sexual intercourse during at least three of their follow-up assessments. Patients who reported both dilation and intercourse had the lowest risk of developing vaginal stenosis of grade ≥ 2 (18%) at 5 years.

The other 317 women were described in the study as having no penetration (13%) or infrequent penetration (23%) and were more likely to experience stenosis of grade ≥ 2 (36% and 37% respectively (P ≤ 0.001)), reported psycho-oncologist, clinical psychologist Kathrin Kirchheiner, PhD, MSc, of the Medical University of Vienna, and colleagues at ASTRO 2023.

While noting that the observational study cannot determine cause and effect, “these long-term data support clinical recommendations worldwide,” said Dr. Kirchheiner at an ASTRO news briefing.

According to Dr. Kirchheiner, external beam radiotherapy, chemotherapy, and internal brachytherapy are the standard of care for locally advanced cervical cancer that cannot be removed by surgery.

Studies have shown that the treatment can cause vaginal shortening and narrowing due to the formation of scar tissue, she said. As a result, there can be “permanent changes in the vaginal tissue that lead to a loss of elasticity. This can often cause problems during the gynecological follow-up examination and pain during sexual intercourse.”

In an earlier reported 2-year analysis of the EMBRACE study (median follow-up of 15 months), the study authors reported that 89% of 588 patients developed grade ≥ 1 vaginal stenosis following their treatment, with 29% at grade ≥ 2 and 3.6% at grade ≥ 3.

The use of medical dilators is commonly recommended after cervical cancer treatment to stretch the vaginal canal. Women are instructed to increase the dilator size over time. But research suggests that adherence may be low.

For the observational, multi-institution study, researchers tracked 1,416 cervical cancer patients from 2008 to 2015 for a median follow-up of 5 years. The new analysis focuses on 882 patients with at least three follow-up assessments, with a median age of 49. Researchers reported that patients who didn’t engage in intercourse or use dilators were most likely to experience vaginal stenosis (37%) vs. those who did both (18%), those who just had intercourse (23%), and those who only used dilators (28%) (P ≤ 0.001).

The findings were confirmed in a multivariable analysis with adjustments for tumor infiltration, age, treatment parameters, and hormonal replacement therapy, the researchers reported.

Regular sexual activity, vaginal dilation, or both were linked to higher risk of mild vaginal dryness at grade ≥ 1 (72% vs. 67% in the no/infrequent penetration group, P = 0.028) and vaginal bleeding at grade ≥ 1 (61% vs. 34% in the no/infrequent penetration group, P ≤ 0.001). There was no link to higher rates of vaginal mucositis.

Dr. Kirchheiner noted that these symptoms can be treated with lubricants, moisturizer, and hormonal replacement therapy.

As for limitations, Dr. Kirchheiner, in a press release provided by ASTRO, noted that “we cannot and should not randomize patients in a clinical trial into groups with and without regular dilation.” She also noted that future research should explore why sexual intercourse had slightly better results than use of dilators, a finding that could be related to blood flow during sexual arousal.

In comments at the news briefing, Akila Viswanathan, MD, MPH, MSc, director of Radiation Oncology and Molecular Radiation Sciences at Johns Hopkins Medicine, Baltimore, praised the new study and noted that quality of life after cervical cancer treatment is “very understudied.”

Vaginal side effects in particular are underreported because physicians often fail to ask about them and patients “are hesitant to accurately describe what they’re feeling,” she said.

The interventions of providing medical dilators and encouraging sexual activity are “very low cost,” Dr. Viswanathan said. But she noted that women – especially older women – may “find the concepts of using a dilator very difficult to understand.”

The study offers the “best evidence to date” supporting vaginal dilation, said Yale University, New Haven, Conn., radiation oncologist Shari Damast, MD, in an interview. It has “a large dataset, longitudinal design, lengthy follow-up, and uses validated tools of measurement. It gives us strong confidence in the efficacy of vaginal dilators.”

In an interview, Deborah Watkins Bruner, RN, PhD, senior vice president for research at Emory University, Atlanta, also praised the research. But she noted that it’s not clear how often vaginal dilation/sexual intercourse should be performed in order to reduce stenosis. “In addition, it is clear that vaginal dilation only is not enough to treat the myriad of symptoms that survivors must deal with,” she said.

Dr. Bruner urged colleagues “to routinely assess symptoms at each visit and offer treatments which should include hormone replacement therapy, vaginal dilation, and appropriate referral for anxiety, depression, or marital problems.”

The study was funded by Elekta and Varian Medical System via the Medical University of Vienna. The study authors, Dr. Bruner, and Dr. Damast have no disclosures. Disclosure information for Dr. Viswanathan was not available.

One in three patients who experience their first bout of atrial fibrillation (AFib) during hospitalization can expect to experience a recurrence of the arrhythmia within the year, new research shows.

The findings, reported in Annals of Internal Medicine, suggest these patients may be good candidates for oral anticoagulants to reduce their risk for stroke.

“Atrial fibrillation is very common in patients for the very first time in their life when they’re sick and in the hospital,” said William F. McIntyre, MD, PhD, a cardiologist at McMaster University, Hamilton, Ont., who led the study. These new insights into AFib management suggest there is a need for primary care physicians to be on the lookout for potential recurrence.

AFib is strongly linked to stroke, and patients at greater risk for stroke may be prescribed oral anticoagulants. Although the arrhythmia can be reversed before the patient is discharged from the hospital, risk for recurrence was unclear, Dr. McIntyre said.

“We wanted to know if the patient was in atrial fibrillation because of the physiologic stress that they were under, or if they just have the disease called atrial fibrillation, which should usually be followed lifelong by a specialist,” Dr. McIntyre said.

Dr. McIntyre and colleagues followed 139 patients (mean age, 71 years) at three medical centers in Ontario who experienced new-onset AFib during their hospital stay, along with an equal number of patients who had no history of AFib and who served as controls. The research team used a Holter monitor to record study participants’ heart rhythm for 14 days to detect incident AFib at 1 and 6 months after discharge. They also followed up with periodic phone calls for up to 12 months. Among the study participants, half were admitted for noncardiac surgeries, and the other half were admitted for medical illnesses, including infections and pneumonia. Participants with a prior history of AFib were excluded from the analysis.

The primary outcome of the study was an episode of AFib that lasted at least 30 seconds on the monitor or one detected during routine care at the 12-month mark.

Patients who experienced AFib for the first time in the hospital had roughly a 33% risk for recurrence within a year, nearly sevenfold higher than their age- and sex-matched counterparts who had not had an arrhythmia during their hospital stay (3%; confidence interval, 0%-6.4%).

“This study has important implications for management of patients who have a first presentation of AFib that is concurrent with a reversible physiologic stressor,” the authors wrote. “An AFib recurrence risk of 33.1% at 1 year is neither low enough to conclude that transient new-onset AFib in the setting of another illness is benign nor high enough that all such transient new-onset AFib can be assumed to be paroxysmal AFib. Instead, these results call for risk stratification and follow-up in these patients.”

The researchers reported that among people with recurrent AFib in the study, the median total time in arrhythmia was 9 hours. “This far exceeds the cutoff of 6 minutes that was established as being associated with stroke using simulated AFib screening in patients with implanted continuous monitors,” they wrote. “These results suggest that the patients in our study who had AFib detected in follow-up are similar to contemporary patients with AFib for whom evidence-based therapies, including oral anticoagulation, are warranted.”

Dr. McIntyre and colleagues were able to track outcomes and treatments for the patients in the study. In the group with recurrent AFib, 1 had a stroke, 2 experienced systemic embolism, 3 had a heart failure event, 6 experienced bleeding, and 11 died. In the other group, there was one case of stroke, one of heart failure, four cases involving bleeding, and seven deaths. “The proportion of participants with new-onset AFib during their initial hospitalization who were taking oral anticoagulants was 47.1% at 6 months and 49.2% at 12 months. This included 73% of participants with AFib detected during follow-up and 39% who did not have AFib detected during follow-up,” they wrote.

The uncertain nature of AFib recurrence complicates predictions about patients’ posthospitalization experiences within the following year. “We cannot just say: ‘Hey, this is just a reversible illness, and now we can forget about it,’ ” Dr. McIntyre said. “Nor is the risk of recurrence so strong in the other direction that you can give patients a lifelong diagnosis of atrial fibrillation.”
 

Role for primary care

Without that certainty, physicians cannot refer everyone who experiences new-onset AFib to a cardiologist for long-term care. The variability in recurrence rates necessitates a more nuanced and personalized approach. Here, primary care physicians step in, offering tailored care based on their established, long-term patient relationships, Dr. McIntyre said.

The study participants already have chronic health conditions that bring them into regular contact with their family physician. This gives primary care physicians a golden opportunity to be on lookout and to recommend care from a cardiologist at the appropriate time if it becomes necessary, he said.

“I have certainly seen cases of recurrent atrial fibrillation in patients who had an episode while hospitalized, and consistent with this study, this is a common clinical occurrence,” said Deepak L. Bhatt, MD, MPH, director of Mount Sinai Heart, New York. Primary care physicians must remain vigilant and avoid the temptation to attribute AFib solely to illness or surgery

“Ideally, we would have randomized clinical trial data to guide the decision about whether to use prophylactic anticoagulation,” said Dr. Bhatt, who added that a cardiology consultation may also be appropriate.

Dr. McIntyre reported no relevant financial relationships. Dr. Bhatt reported numerous relationships with industry.
