Mastectomies, reconstruction, on the rise for women with early stage disease
Significant increases in the mastectomy rate among women with early breast cancer who were candidates for breast conservation surgery during a recent 14-year period in the United States were accompanied by increases in breast reconstruction and bilateral mastectomies, in a retrospective cohort study that tracked national trends in this group of women.
The results, based on outcomes of about 1.2 million women with early breast cancer in a national oncology outcomes database, “are generally consistent with trends noted in other state, regional, and national studies,” reported Dr. Kristy Kummerow of the division of surgical oncology and endocrine surgery, Vanderbilt University, Nashville, Tenn., and her associates. While they speculated on some of the reasons behind these findings, “further research is needed to understand patient, provider, policy, and social factors associated with these trends,” they concluded in the study, which was published online Nov. 19 in JAMA Surgery (doi:10.1001/jamasurg.2014.2895).
While the use of breast conservation surgery (BCS) as an alternative to mastectomy for early-stage breast cancer increased steadily after studies showed the two approaches had equal outcomes, and after endorsement by a National Institutes of Health Consensus Conference in 1990, the authors noted that there has been evidence that the trend is reversing.
Using data from the National Cancer Data Base, which collects outcomes data on about 70% of the patients diagnosed with cancer in the United States, they evaluated trends in mastectomies among adult women newly diagnosed with early (unilateral) breast cancer from January 1998 through December 2011. Women were included if TNM stage information was available, tumors were 5 cm or less with nine or fewer involved axillary lymph nodes based on clinical staging, and they underwent BCS (lumpectomy, segmental mastectomy, or re-excision of the biopsy site) or mastectomy (subcutaneous, total, modified radical or radical).
Over the 14-year period, among the approximately 1.2 million women who met the criteria, 64.5% had BCS and 35.5% had a mastectomy. The women who had a mastectomy were slightly younger (mean age 59.6 years vs. 61.6 years), and the proportion of racial and ethnic minorities was lower in this group.
The proportion of women eligible for BCS who underwent a mastectomy increased from 34.3% in 1998 to 37.8% in 2011, a statistically significant increase, “with steeper increases” seen in women who had node-negative and noninvasive disease, the authors reported. For the most recent 8-year period – 2003 to 2011 – the rate increased by 34%, “with the most notable rise in mastectomy rates occurring after 2006,” and the highest increases seen among women with clinically node-negative disease. Age and tumor size were “the most influential covariates,” with younger women “more likely to undergo mastectomy irrespective of tumor size, while in older women mastectomy was strongly associated with tumor size greater than 2 cm.”
During the period studied, there were significant increases in breast reconstruction and bilateral mastectomies among women who had mastectomies, which were secondary outcome measures. The proportion of women who underwent breast reconstruction increased from 11.6% in 1998 to 36.4% in 2011, and the proportion of women who had a bilateral mastectomy for unilateral disease increased from 1.9% to 11.2% during this period. The trend toward more reconstruction surgery could be due to 1998 legislation mandating insurance coverage of reconstructive surgery after mastectomy, the authors wrote.
Study limitations included missing clinical staging information for a large proportion of the women, no information on BRCA status or triple-negative tumors, and an inability to determine why the mastectomy was performed in individual cases, they noted.
None of the authors had disclosures to report. The study is based on work supported by the Office of Academic Affiliations, Department of Veterans Affairs, the VA National Quality Scholars Program, and with the use of facilities at the VA Tennessee Valley Healthcare System, Nashville.
In an accompanying editorial, Dr. Bonnie Sun and Dr. Michael Zenilman wrote that the “surprising rise” in the mastectomy rate for women with early stage breast cancers in this study raises various questions, including whether all the patients were candidates for BCS, which is difficult to determine “without accounting for findings on magnetic resonance imaging, family history, clinical stage, and tumor to breast ratio.” Another question is why the women chose a mastectomy and whether the reasons for that choice were valid. “While the choice to pursue mastectomy over BCS is never wrong, it must be made for the right reasons,” they said, adding, “when presenting these surgical options, we must ensure that decisions are not based on misconceptions.” This study “ should at least serve as a wake-up call that as we fulfill that responsibility, and use every modality of care to give patients the best quality of life and survival advantage, the guidelines may need to change again,” they wrote (JAMA Surgery 2014 Nov. 19 [doi:10.1001/jamasurg.2014.2902)].

Total thyroidectomy more likely with younger thyroid cancer patients
CORONADO, CALIF. – Patients with differentiated thyroid cancer who were younger than age 45 years were more likely to undergo total or near-total thyroidectomy and to receive radioactive iodine, compared with their older counterparts, a large registry analysis demonstrated.
In addition, younger patients were more likely to be Hispanic and female and to have papillary carcinoma, lead study author Dr. Thomas J. Semrad reported during the annual meeting of the American Thyroid Association.
“Not much is known about how treatment administration differs between younger and older patients with thyroid cancer,” Dr. Semrad of the division of hematology/oncology at the University of California, Davis, Comprehensive Cancer Center, Sacramento, said in an interview. “Some data suggest that perhaps patients younger than age 15 years may respond better to radioactive iodine and may present with more advanced disease. But not much is known about how they’re treated.”
To find out, Dr. Semrad and his associates used the California Cancer Registry to identify 23,629 patients who were diagnosed with differentiated thyroid cancer between 2004 and 2011. They divided the patients into two cohorts: younger (defined as those younger than 45 years) and older (those 45 years or older). Treatment variables of interest included total or near-total thyroidectomy, other types of thyroid surgery, and the administration of radioactive iodine (RAI). The researchers compared the descriptive statistics between the two groups and used univariate and multivariate logistic regression to identify predictors of the treatment administered.
Compared with older patients, younger patients were significantly more likely to be Hispanic (33% vs. 22%), to be female (83% vs. 75%), to have papillary carcinoma (93% vs. 91%), and to have lymph node involvement (32% vs. 20%, all P < .0001).
Overall, the majority of patients (86%) underwent total or near-total thyroidectomy, but the surgery was slightly and significantly more common in younger patients, compared with their older counterparts (88% vs. 85%, P < .0001). Younger patients also were significantly more likely to receive RAI (55% vs. 49%, P < .0001).
On multivariate analysis, statistically significant predictors of total thyroidectomy, compared with other thyroid surgery, included younger age (odds ratio, 1.193); higher socioeconomic status (OR, 1.263, for higher-middle SES and OR, 1.325, for highest SES); higher T stage (OR, 1.848, for T2; OR, 2.473, for T3; and OR, 2.908, for T4); and papillary histology (OR, 0.349).
At the same time, statistically significant predictors of RAI administration included younger age (OR, 1.116); higher SES (OR, 1.410, for higher-middle SES and OR, 1.307, for highest SES); more advanced T stage (OR, 2.194 for T2; OR, 2.084, for T3; and OR, 1.527, for T4); node positivity (OR, 0.481), and total thyroidectomy (OR, 3.76).
“As we expected, the younger population was more likely to be female, but we did find that the younger population was also more likely to be Hispanic,” Dr. Semrad said. “We don’t know if they were native Hispanics or if it has something to do with immigration rates.”
Dr. Semrad acknowledged certain limitations of the study, including the risk of misclassification bias in registry data, the lack of details about surgical procedures performed, and the fact that the radioiodine dose was not captured.
“We have data regarding the T stage, the nodal stage, and the number of lymph nodes examined, but we don’t have some of the finer histology data,” he said.
Even so, he characterized the findings as “provocative in suggesting that perhaps our treatment patterns in younger patients are different. With more aggressive surgery and more use of radioactive iodine, that can have potential implications in terms of long-term side effects and follow-up.”
The researchers said they plan to use linked administrative data to analyze initial and subsequent thyroid surgical procedures in this patient population.
The study was supported by a grant from the National Institutes of Health. Dr. Semrad reported having no relevant financial disclosures.

Antibiotic bowel prep significantly reduces colon surgery infections
SAN FRANCISCO – Oral antibiotics with mechanical bowel preparation significantly reduce surgical site infections, length of hospital stay, and readmissions in both open and laparoscopic elective colorectal surgery, according to a review of 8,415 cases in the National Surgery Quality Improvement Program.
It “should be adopted for elective colorectal surgery,” concluded the investigators, led by colorectal surgeon Melanie Morris of the University of Alabama at Birmingham.
A quarter of the patients had no bowel prep, 45% had mechanical prep alone – GoLytely or another laxative, and 30% received both oral antibiotics and mechanical prep. Partial colectomy and sigmoid resections were the most common procedures, generally for neoplasms or diverticulitis.
Overall, 15% of the no-prep group, 12% of the mechanical prep group, and 6.5% of the oral antibiotic plus mechanical prep group developed subsequent surgical site infections (SSIs), a statistically significant difference. Results were similar when broken down into superficial, deep wound, and organ space infections (J. Am. Coll. Surg. 2014:219;S18-19).
On multivariate analysis and after adjusting for diabetes, smoking, age, and other potential confounders, the antibiotic group was 54% less likely than the no-prep group to develop an SSI (odds ratio 0.46), 26% less likely to be readmitted (OR 0.74), and more likely to leave the hospital earlier, at about 4 days instead of 5 (OR 0.90). SSIs and readmissions were only slightly less likely in the mechanical prep–only group, compared with the no-prep group, and there was no difference in length of stay.
There were fewer anastomotic leaks, fewer cases of sepsis, less significant bleeding, and other benefits for oral antibiotics with mechanical preparation. In addition, there was a protective effect against 30-day mortality in open procedures.
“Even in the minimally invasive group,” about two-thirds of patients, “oral antibiotic prep … was protective for surgical site infections,” Dr. Morris said at the annual clinical congress of the American College of Surgeons.
Still, bowel prep remains “a very controversial topic.” Nationwide some surgeons prep, some don’t. “People have very strong beliefs that may or may not be rooted in the data,” she said.
There are concerns about fluid and electrolyte disturbances, Clostridium difficile overgrowth, and other potential problems. Plus, mechanical preparation hasn’t worked any better than placebo in recent studies, but many of those studies didn’t include oral antibiotics. Effective bowel prep includes both, Dr. Morris said.
It’s possible that confounders might have been at work in the Alabama study. Perhaps surgeons shied away from bowel prep in older, sicker patients, but the rate of acute renal injury was the same in all three study groups at about 0.9%, suggesting similar background comorbidities.
“I don’t think confounding issues” explain the findings. Previously, “we’ve shown the benefit of oral antibiotic bowel prep in a [Veterans Affairs] cohort, and now we’ve shown it in this national cohort,” Dr. Morris said (Dis. Colon. Rectum 2012;55:1160-6).
After a marked reduction in surgical site infections in the VA study, “we changed our practices. We now do mechanical and oral antibiotic preps and have seen a 50% reduction in our SSI rate. We don’t feel like we are doing anything else differently,” she said.
Dr. Morris has no disclosures.

On multivariate analysis and after adjusting for diabetes, smoking, age, and other potential confounders, the antibiotic group was 54% less likely than the no-prep group to develop an SSI (odds ratio 0.46), 26% less likely to be readmitted (OR 0.74), and more likely to leave the hospital earlier, at about 4 days instead of 5 (OR 0.90). SSIs and readmissions were only slightly less likely in the mechanical prep–only group, compared with the no-prep group, and there was no difference in length of stay.
There were fewer anastomotic leaks, fewer cases of sepsis, less significant bleeding, and other benefits for oral antibiotics with mechanical preparation. In addition, there was a protective effect against 30-day mortality in open procedures.
“Even in the minimally invasive group,” about two-thirds of patients, “oral antibiotic prep … was protective for surgical site infections,” Dr. Morris said at the annual clinical congress of the American College of Surgeons.
Still, bowel prep remains “a very controversial topic.” Nationwide some surgeons prep, some don’t. “People have very strong beliefs that may or may not be rooted in the data,” she said.
There are concerns about fluid and electrolyte disturbances, Clostridium difficile overgrowth, and other potential problems. Plus, mechanical preparation hasn’t worked any better than placebo in recent studies, but many of those studies didn’t include oral antibiotics. Effective bowel prep includes both, Dr. Morris said.
It’s possible that confounders might have been at work in the Alabama study. Perhaps surgeons shied away from bowel prep in older, sicker patients, but the rate of acute renal injury was the same in all three study groups at about 0.9%, suggesting similar background comorbidities.
“I don’t think confounding issues” explain the findings. Previously, “we’ve shown the benefit of oral antibiotic bowel prep in a [Veterans Affairs] cohort, and now we’ve shown it in this national cohort,” Dr. Morris said (Dis. Colon. Rectum 2012;55:1160-6).
After a marked reduction in surgical site infections in the VA study, “we changed our practices. We now do mechanical and oral antibiotic preps and have seen a 50% reduction in our SSI rate. We don’t feel like we are doing anything else differently,” she said.
Dr. Morris has no disclosures.
SAN FRANCISCO – Oral antibiotics with mechanical bowel preparation significantly reduce surgical site infections, length of hospital stay, and readmissions in both open and laparoscopic elective colorectal surgery, according to a review of 8,415 cases in the National Surgery Quality Improvement Program.
It “should be adopted for elective colorectal surgery,” concluded the investigators, led by colorectal surgeon Melanie Morris of the University of Alabama at Birmingham.
A quarter of the patients had no bowel prep, 45% had mechanical prep alone – GoLytely or another laxative, and 30% received both oral antibiotics and mechanical prep. Partial colectomy and sigmoid resections were the most common procedures, generally for neoplasms or diverticulitis.

Low-stage colon cancers need to be followed post surgery for recurrence
SAN FRANCISCO – Patients with stage I colorectal cancer should be followed as closely as patients with higher-stage primary tumors after resection, according to a prospective 6-year surveillance study of 1,202 British patients.
The reason is that the incidence of recurrences that can be treated surgically with curative intent is the same in stage I patients as it is in patients with stage II and III primaries, about 6% (J. Am. Coll. Surg. 2014:219;e46-47).
Following resection with clear margins, the patients were randomized about 300 per group to either serial CT surveillance, serial carcinoembryonic antigen (CEA) monitoring, both, or minimum surveillance, and followed for a median of 4.4 years. About a quarter of the subjects had Dukes’ A primaries and a quarter Dukes’ C primaries, and about half had Dukes’ B primaries. The A, B, C designations are similar to the stage I, II, and III designations more common in the United States.
On both sides of the Atlantic, guidelines focus on active surveillance for higher-stage primaries, but are ambivalent about monitoring stage I tumors because they are less likely to recur and the benefit of follow-up has been uncertain.
That needs to change because treatable recurrences are what matters, and they are as likely in low-stage disease as in high-stage disease, lead investigator Dr. Sian Pugh, a colorectal surgeon at the University of Southampton (England), said at the annual clinical congress of the American College of Surgeons.
“Picking up recurrences that are not treatable doesn’t help anyone; it just gives you bad news earlier,” she said. The benefit of follow-up is “finding treatable disease, and that’s independent of the stage of the primary tumor. We recommend equivalent follow-up for all patients with resected Dukes’ A-C colorectal cancer. The guidelines [should] be reconsidered,” she asserted.
Her team also thinks that the most cost-effective way to monitor patients is probably with CEA monitoring every 3 months for the first 2 years, CEA monitoring every 6 months thereafter until year 5, and a single CT at 12-18 months to catch recurrences that don’t express CEA. That strategy was three times more likely than minimal surveillance to find treatable recurrences, about the same as serial CTs and serial CTs with regular CEA monitoring.
“We don’t think patients need to be followed up quite as intensively as the guidelines suggest,” – for instance, CT scans every 6 months – “but we are waiting for more health economic analysis,” Dr. Pugh said.
Although treatable recurrences were equally likely in all the groups, they were more common in patients with lower-stage primary cancers. Among recurrences in patients with Dukes’ A primary tumors, 50% (13/26) were treated surgically with curative intent, compared with 40% (32/81) in patients with Dukes’ B primaries and 24% (20/82) in those with Dukes’ C.
Pulmonary recurrence was most frequent with rectal primary tumors, and multisite recurrence was most common from right-colonic cancers. Median survival following recurrence was 2.28 years and was influenced by stage and site of primary. Following recurrence, survival was highest in those with lower-stage and rectal primaries, and lowest in patients with higher-stage primaries and recurrence from the right colon.
Dr. Pugh had no disclosures. The work was funded by the U.K. National Health Service.
There’s a lot of heterogeneity in the United States with regard to how frequently people get surveillance imaging and CEA for colon cancer recurrence. The study is helpful because it presents data that inform the decision.
These data suggest that CEA on a regular basis and a CT scan at 1 year are enough. This may be a more rational, cost-effective way to screen people and still achieve what we’re trying to achieve: picking up treatable recurrences.

Enhanced thyroid cancer guidelines expected in 2015
CORONADO, CALIF. – Expect significant enhancements to the updated thyroid cancer management guidelines from the American Thyroid Association, due to be released in early 2015.
Last updated in 2009, the goal of the new guidelines is to “be evidence based and helpful,” guidelines task force chair Dr. Bryan R. Haugen said at the annual meeting of the American Thyroid Association. For example, the new guidelines will contain 101 recommendations, up from 80 in the 2009 version; 175 subrecommendations, up from 103; and 998 references, up from 437. “Still, 59 of the existing 80 recommendations are not substantially changed, showing a general stability in our field over the past 5 to 6 years,” he said.
One enhancement is a definition of risk of structural disease recurrence in patients without structurally identifiable disease after initial therapy for thyroid cancer. Low risk is defined as intrathyroidal differentiated thyroid cancer involving up to five metastases less than 0.2 cm in size. Intermediate risk is defined as the presence of aggressive histology, minor extrathyroidal extension, vascular invasion, or more than five involved lymph nodes with metastases 0.2-0.3 cm in size. High risk is defined as the presence of gross extrathyroidal extension, incomplete tumor resection, distant metastases, or lymph node metastases greater than 3 cm in size.
The guidelines also include a table that defines a patient’s response to therapy as a dynamic risk assessment. “This best applies to the low- to intermediate-risk patients, although it definitely applies to high risk as well,” said Dr. Haugen, who heads the division of endocrinology, metabolism, and diabetes at the University of Colorado Health Sciences Center, Denver. “It’s [a] strong recommendation based on low-quality evidence to use this risk-based response to therapy. A lot of this data is generated from patients who’ve had a thyroidectomy and have received radioiodine. So we’re on a bit more shaky ground right now in a patient who’s had a thyroidectomy but no radioiodine, or a patient who’s had a lobectomy.”
Other changes include the concept that it’s not necessary to biopsy every nodule more than 1 cm in size. “We’re going to be guided by the sonographic pattern in who we biopsy and how we monitor them,” Dr. Haugen explained. “A new recommendation adds follow-up guidance for nodules that do not meet FNA [fine-needle aspiration] criteria. We’re also recommending use of the Bethesda Cytology Classification System for cytology.”
Changes in the initial management of thyroid cancer include a recommendation for cross-sectional imaging with contrast for higher-risk disease and the consideration of lobectomy for some patients with tumors 1-4 cm in size. “This is a controversial recommendation,” Dr. Haugen said. “We got some feedback from members asking if you do it, what’s the TSH target? Should we give them synthetic levothyroxine? We are revising the guidelines based on this feedback to help guide clinicians.”
The new guidelines also call for more detailed/standardized pathology reports, with inclusion of lymph node size, extranodal invasion, and the number of invaded vessels. “I’ve talked to a number of pathologists and clinicians who are very happy about this guidance,” he said. “We also need to look at tumor stage, recurrence risk, and response to therapy in our patients, and the use of selective radioiodine. There is some more information on considering lower administered activities, especially in the lower-risk patients.”
For the first time, the guidelines include a section on radioiodine treatment for refractory differentiated thyroid cancer, including tips on directed therapy, clinical trials, systemic therapy, and bone-specific therapy.
Dr. Haugen disclosed that he has received grants and research support from Veracyte and Genzyme.

EXPERT ANALYSIS FROM THE ATA ANNUAL MEETING
VIDEO: An easy way to improve breast biopsy practices
SAN FRANCISCO – Surgeons improve if they know they are behind the curve, according to Dr. Judy A. Tjoe, a breast cancer surgeon with Milwaukee-based Aurora Health Care.
She and her colleagues used that principle to significantly increase Aurora’s use of minimally invasive breast biopsies, the gold standard to diagnose breast cancer.
Although Dr. Tjoe and the system’s other three dedicated breast surgeons were using MIBB as appropriate, they found that 9 of 42 general surgeons (21%) were not, opting instead for open biopsies.
All it took to fix the problem was letting those surgeons know that minimally invasive breast biopsies was the preferred method, and that most of their peers were using it.
In a video interview at the American College of Surgeons Clinical Congress, Dr. Tjoe, also chair of Aurora’s quality committee for breast cancer care, explained why that message was so powerful, and how, in an era of pay for performance, the project is a model for improving health care without punitive measures.

No survival benefit of RAI seen in early-stage thyroid cancer
CORONADO, CALIF. – In a large cohort of patients with differentiated thyroid cancer, the use of radioactive iodine was associated with improved disease-specific survival in those with advanced disease but not in those with papillary thyroid microcarcinoma.
“Everything in medicine is a risk-benefit balance,” lead author Dr. Ryan K. Orosco said in an interview in advance of the annual meeting of the American Thyroid Association, where the work was presented. “Any two patients that receive radioactive iodine (RAI) for differentiated thyroid cancer are likely to have different survival benefit from that therapy. This study provides a quantitative comparison of the impact of RAI in various patient subgroups.”
In one of the largest studies of its kind, Dr. Orosco of the division of head and neck surgery at the University of California, San Diego, and his associates identified 85,740 patients with differentiated thyroid carcinoma from the Surveillance, Epidemiology, and End Results database from 1973 through 2009. They used multivariate analyses to explore the association between RAI and cancer-specific survival in 149 population subgroups, controlling for age, decade of diagnosis, race, gender, tumor type, nodal involvement, metastasis stage, and RAI therapy.
More than three-quarters of the patients (78%) were female, 68% were white, their mean age at diagnosis was 46 years, and the median follow-up time was 85 months. The researchers found that nearly half of patients (43%) received RAI. By American Joint Committee on Cancer stage, RAI was used in 55% of stage I patients, 41% of stage II patients, 94% of stage III patients, and 85% of stage IV patients. In addition, 42% of patients with T1a disease and 88% of those with T4 disease received RAI.
Use of RAI was positively associated with survival in the overall cohort (hazard ratio 1.3; P = .002), while statistically significant HRs for RAI were observed in 49 population subgroups. In patients with metastatic disease, use of RAI was associated with a decreased risk for disease-specific mortality (HR range of 2.28-3.82). Protective effects of RAI were also observed in patients with regional metastases (HR 1.4-1.9), those with T3-positive tumors (HR 1.36-1.39), those with T4 tumors (HR 1.85), and in those with stage IV disease (HR 1.47-1.73).
Dr. Orosco and his associates observed a negative effect of RAI in patients with macropapillary carcinoma. Specifically, those with T1a disease had an increased likelihood of thyroid cancer–specific mortality (HR .13; P less than .001), while similar associations were seen in multiple subgroups of patients with T1a disease (HR 0.04-0.25). No statistically significant effects of RAI were observed in patients with T1b or T2 tumors.
“RAI appears to offer the best survival impact in patients with advanced differentiated thyroid carcinoma,” Dr. Orosco said. “Its use in early-stage patients should be carefully considered.”
In their abstract, the researchers noted that the findings “might help clinicians personalize RAI therapy to specific differentiated thyroid cancer populations – offering treatment in patients most likely to benefit, and sparing others unnecessary costs and potential side effects.”
Dr. Orosco acknowledged certain limitations of the study, including the fact that the SEER database does not contain details about each patient’s surgery, the dose of RAI used, other comorbidities, or data on cancer recurrence. “This study does not attempt to explore the reasons behind the apparent survival disadvantage seen in patients with T1a disease,” he said. “We don’t know exactly why early-stage patients have an increased risk of disease-specific mortality when RAI is used. Additional work is needed to explore this further.”

CORONADO, CALIF. – In a large cohort of patients with differentiated thyroid cancer, the use of radioactive iodine was associated with improved disease-specific survival in those with advanced disease but not in those with papillary thyroid microcarcinoma.
“Everything in medicine is a risk-benefit balance,” lead author Dr. Ryan K. Orosco said in an interview in advance of the annual meeting of the American Thyroid Association, where the work was presented. “Any two patients that receive radioactive iodine (RAI) for differentiated thyroid cancer are likely to have different survival benefit from that therapy. This study provides a quantitative comparison of the impact of RAI in various patient subgroups.”
In one of the largest studies of its kind, Dr. Orosco of the division of head and neck surgery at the University of California, San Diego, and his associates identified 85,740 patients with differentiated thyroid carcinoma from the Surveillance, Epidemiology, and End Results database from 1973 through 2009. They used multivariate analyses to explore the association between RAI and cancer-specific survival in 149 population subgroups, controlling for age, decade of diagnosis, race, gender, tumor type, nodal involvement, metastasis stage, and RAI therapy.
More than three-quarters of the patients (78%) were female, 68% were white, their mean age at diagnosis was 46 years, and the median follow-up time was 85 months. The researchers found that nearly half of patients (43%) received RAI. By American Joint Committee on Cancer stage, RAI was used in 55% of stage I patients, 41% of stage II patients, 94% of stage III patients, and 85% of stage IV patients. In addition, 42% of patients with T1a disease and 88% of those with T4 disease received RAI.

VIDEO: Risks for anastomotic leak after colectomy identified
SAN FRANCISCO– A large retrospective study identified risk factors for anastomotic leak within 30 days of colectomy.
The analysis of data on 13,684 patients looked at a multicenter cohort, compared with previous smaller studies that generally focused on single institutions, Dr. Emily F. Midura and her associates reported at the annual clinical congress of the American College of Surgeons.
In a video interview at the meeting, Dr. Midura described the risk factors identified in the study.
The 4% of patients who developed a leak averaged 13 days in the hospital, compared with 8 days for patients with no leak, said Dr. Midura of the University of Cincinnati. A total of 6% of patients who developed an anastomotic leak died, compared with a 2% mortality rate in patients without a leak.
Indications for colectomy included cancer in 42% of patients, diverticulitis in 23%, inflammatory bowel disease in 6%, and other reasons in the rest of the cohort.

AT THE ACS CLINICAL CONGRESS
Breast cancer margins, radiotherapy, axillary dissection evolve
SAN FRANCISCO – Recent research and guidelines have changed how surgeons should be thinking about some aspects of treating breast cancer, a panel of experts said in a press briefing at the annual clinical congress of the American College of Surgeons.
New guidelines on surgical margins, data supporting radiation rather than complete lymphadenectomy for patients with positive sentinel nodes, and other studies supporting targeted radiation therapy instead of whole-breast irradiation after lumpectomy should be on a surgeons’s radar, the speakers said.
The first U.S. guidelines on surgical margins for lumpectomy in women with breast cancer who are planning to undergo whole-breast radiation therapy adopted a standard of “no ink on tumor,” meaning no cancer at the edge of the tissue that was removed, Dr. Richard J. Gray said. The 2014 joint guidelines from the Society of Surgical Oncology and the American Society of Radiation Oncology based the recommendations on a meta-analysis of studies that found no advantage to wider excision margins for preventing in-breast recurrence (Ann. Surg. Oncol. 2014;21:717-730).
Previously, many surgeons sought to take 1, 2, or 3 mm of normal tissue around the cancer removed to reduce the risk of recurrence, he said.
“This guideline will become the standard throughout the United States. The evidence on which this is based is reasonable, but it will be important for individual institutions and national databases to track the rates of local recurrence over time as these guidelines are implemented,” said Dr. Gray of the Mayo Clinic, Scottsdale, Ariz. He confessed to being “a recovering addict” to margins of 2 mm or greater.
The guidelines apply only to patients with invasive cancer undergoing breast-conserving treatment, he noted. There are no guidelines yet specifically for surgical margins in women undergoing mastectomy for breast cancer, nor for women with ductal carcinoma in situ (DCIS).
While there is no evidence that a margin width wider than “no ink on tumor” is better for women undergoing mastectomy, Dr. Gray cautioned against extrapolating the guidelines to women having mastectomies “because they will generally not undergo adjuvant radiation therapy,” he said.
For women with DCIS, the available evidence suggests that a minimum 2-mm margin of excision is reasonable for those undergoing lumpectomy or at least negative margins (no ink on tumor) for those undergoing mastectomy, Dr. Gray said. Wider margins may help select patients with DCIS who undergo lumpectomy to avoid adjuvant radiation therapy, he added.
A separate recent study should change the way surgeons approach decisions about axillary surgery in patients with breast cancer, Dr. Roshni Rao said. She reported on a study that randomized women who had cancer in sentinel lymph nodes after mastectomy to further treatment by removing the rest of the lymph nodes under the arm, as is common practice, or to radiation of the lymph nodes area.
Rates of cancer recurrence did not differ between groups but the radiation approach significantly reduced the risk of lymphedema and other morbidity, said Dr. Rao of the University of Texas Southwestern Medical Center, Dallas.
“Going forward, we’re going to be performing less and less axillary lymph node dissections,” she said.
Also on the topic of radiation therapy, two recent studies of targeted breast irradiation rather than whole-breast radiotherapy suggest that the targeted approach may be beneficial, Dr. Courtney A. Vito said. Whole-breast radiation after lumpectomy reduces the risk of local recurrence by 50%, previous studies have shown, but it comes with potential side effects including burns, lymphedema, and damage to underlying structures like the heart and lungs. Patients who don’t live near specialized radiation centers may not be able to access the daily month-long treatments.
A randomized Italian trial of 1,305 patients found similar rates of overall survival or breast cancer–specific survival in patients treated with whole-breast radiation therapy or with intraoperative radiation therapy, in which a single, more intense dose of radiation is directed just at the site of lumpectomy during surgery. Survival rates were similar between groups but the rate of local recurrence after 5 years was 10 times higher in the intraoperative radiation group (4.4%), compared with the whole-breast radiation group (0.4%) (Lancet Oncol. 2013;14:1269-77).
Subset analyses showed, however, that most of the recurrences were in women who would not be considered ideal candidates for intraoperative radiotherapy in the United States because they had tumors larger than 2 cm, four or more positive lymph nodes, estrogen receptor–negative tumors, or other aggressive tumor biology, said Dr. Vito of the City of Hope National Medical Center, Duarte, Calif. Recurrence rates were more favorable in patients with lower-risk tumors.
“When you take out the high-risk group, the data actually look a lot better,” she said.
A separate randomized British trial of intraoperative radiation therapy produced similar overall results in 1,721 patients, but two-thirds of patients would be considered unsuitable or cautionary in the United States, Dr. Vito said (Lancet 2014;383:603-613).
Overall survival and breast cancer survival were similar in the intraoperative and whole-breast radiation groups except for worse outcomes in patients who had intraoperative radiation done as a second surgery after the operation to perform lumpectomy.
The rate of deaths from causes other than breast cancer was higher in the whole-breast radiation group, in many cases due to cardiac events, Dr. Vito noted. Whole-breast radiation on the left side of the chest has been shown to accelerate atherosclerosis of the vessels in the heart, and it may be that avoiding this through intraoperative targeted radiotherapy may provide a cardiovascular benefit, though this is yet to be proven, she added.
A separate presentation at the meeting explored the increasing rate of women with cancer in one breast who choose prophylactic mastectomy of the healthy contralateral breast. The rate of prophylactic contralateral mastectomy increased 150% between 1998 and 2003 in the United States, from 1.8% to 4.5%, Dr. Swati Kulkarni said.
She and her associates surveyed a diverse cohort of 150 women before surgery for cancer in one breast and again 6 months after surgery. Only 14% said that medical staff had provided information about removing the healthy breast along with the cancerous breast; 63% said they did not get that information, and 23% were unsure, reported Dr. Kulkarni of the University of Chicago.
Thirty-nine percent of patients had thought about their surgical choices before they were diagnosed with breast cancer, and 58% of the cohort wanted or considered contralateral prophylactic mastectomy.
Patients with a family history of breast cancer who had undergone genetic testing were significantly more likely to want or consider prophylactic contralateral mastectomy. Factors that were not significantly associated with prophylactic contralateral mastectomy were family history by itself, age, race, insurance status, cancer stage, use of breast MRI, or having one or more biopsies.
The findings suggest that education about prophylactic mastectomy is needed “inside and outside of the doctor’s office,” Dr. Kulkarni said.
The speakers reported having no financial disclosures.
