Breast Cancer-Major changes in the American Joint Committee on Cancer eighth edition cancer staging manual.

Answer questions and earn CME/CNE The revision of the eighth edition of the primary tumor, lymph node, and metastasis (TNM) classification of the American Joint Commission of Cancer (AJCC) for breast cancer was determined by a multidisciplinary team of breast cancer experts. The panel recognized the need to incorporate biologic factors, such as tumor grade, proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression prognostic panels into the staging system. AJCC levels of evidence and guidelines for all tumor types were followed as much as possible. The panel felt that, to maintain worldwide value, the tumor staging system should remain based on TNM anatomic factors. However, the recognition of the prognostic influence of grade, hormone receptor expression, and HER2 amplification mandated their inclusion into the staging system. The value of commercially available, gene-based assays was acknowledged and prognostic input added. Tumor biomarkers and low Oncotype DX recurrence scores can alter prognosis and stage. These updates are expected to provide additional precision and flexibility to the staging system and were based on the extent of published information and analysis of large, as yet unpublished databases. The eighth edition of the AJCC TNM staging system, thus, provides a flexible platform for prognostic classification based on traditional anatomic factors, which can be modified and enhanced using patient biomarkers and multifactorial prognostic panel data. The eighth edition remains the worldwide basis for breast cancer staging and will incorporate future online updates to remain timely and relevant.

Treatment Differences for Adrenocortical Carcinoma by Race and Insurance Status.

INTRODUCTION: To determine if treatment and clinical outcomes of adrenocortical carcinoma (ACC) vary by race and insurance status. METHODS: ACC patients from the National Cancer Database (2004-2017) were reviewed. Race was defined as White versus minority (Black and Hispanic). Insurance types were private (PI) versus other (Medicaid/uninsured/unknown). Metastatic ACC (M-ACC) was defined as distant metastases at the time of diagnosis; nonmetastatic ACC (NM-ACC) patient had no distant disease. RESULTS: Of 2351 NM-ACC patients, 83.6% were White and 16.4% minority. There were 1216 M-ACC patients, with 80.3% White and 19.8% minority. Both White NM-ACC and M-ACC patients had more PI (each P < 0.001). PI NM-ACC was associated with a shorter duration from diagnosis to first treatment (14 versus 18 d, P = 0.005). Both NM-ACC and M-ACC with PI were more likely to receive surgery (92.6% versus 86.9%, P = 0.001 and 35.4% versus 27%, P = 0.02) and to receive surgery sooner (13 versus 16 d, P = 0.03). M-ACC with PI were more likely to receive chemotherapy (63.6% versus 54.3%, P = 0.01) and to have lymph nodes examined (14.8% versus 8.6%, P = 0.02). Length of stay postoperatively was shorter for White NM-ACC (6 versus 7 d, P = 0.04) and M-ACC (8 versus 17 d, P = 0.02). For NM-ACC and M-ACC, the 30-d readmission, 90-d mortality, and overall survival were similar by race. A multivariable analysis showed minorities (OR 0.69, 95% confidence interval 0.54-0.88, P = 0.003) and patients without PI (OR 0.75, 95% confidence interval 0.58-0.97, P = 0.03) were less likely to have surgery. However, a multivariable analysis showed survival was similar for White versus minority patients and PI versus other. CONCLUSIONS: White NM-ACC or M-ACC and PI were more likely to receive surgery and timely multimodality care. These disparities were not associated with differences in 90-d mortality or overall survival.

Virtual Surgical Fellowship Recruitment During COVID-19 and Its Implications for Resident/Fellow Recruitment in the Future.

BACKGROUND: The COVID-19 pandemic has overlapped with the scheduled interview periods of over 20 surgical subspecialty fellowships, including the Complex General Surgical Oncology (CGSO) fellowships in the National Resident Matching Program and the Society of Surgical Oncology's Breast Surgical Oncology fellowships. We outline the successful implementation of and processes behind a virtual interview day for CGSO fellowship recruitment after the start of the pandemic. METHODS: The virtual CGSO fellowship interview process at the University of Chicago Medicine and NorthShore University Health System was outlined and implemented. Separate voluntary, anonymous online secure feedback surveys were email distributed to interview applicants and faculty interviewers after the interview day concluded. RESULTS: Sixteen of 20 interview applicants (80.0%) and 12 of 13 faculty interviewers (92.3%) completed their respective feedback surveys. Seventy-five percent (12/16) of applicants and all faculty respondents (12/12) stated the interview process was 'very seamless' or 'seamless'. Applicants and faculty highlighted decreased cost, time savings, and increased efficiency as some of the benefits to virtual interviewing. CONCLUSIONS: Current circumstances related to the COVID-19 pandemic require fellowship programs to adapt and conduct virtual interviews. Our report describes the successful implementation of a virtual interview process. This report describes the technical steps and pitfalls of organizing such an interview and provides insights into the experience of the interviewer and interviewee.

Trends in nonoperative management of papillary thyroid microcarcinoma.

BACKGROUND: In 2010, a Japanese trial of nonoperative management for papillary thyroid microcarcinomas (PTmC) was published. This study determines if the prevalence of nonoperative management in the United States has changed and if there are predictors of this approach. METHODS: Patients treated for PTmC between 2004 and 2015 in the National Cancer Data Base were identified. Inclusion criteria were: classic or follicular variant papillary cancer histology, tumor size 1 to 10 mm, cN0 disease and no extrathyroidal extension or metastatic disease. Nonoperative management was assessed over time and compared between 2004-2010 and 2010-2015. Logistic regression identified factors associated with nonoperative management. RESULTS: Of 65 381 PTmC patients, 344 (0.5%) were treated nonoperatively. The annual rate of nonoperative management was similar at 0.6% in 2004 to 0.4% in 2010 (P = .755) but increased to 0.9% in 2015 (P < .001). There was no difference in patient age, race, comorbidities, or reason for nonoperative management between the two periods. Academic centers managed more patients nonoperatively. Multivariable logistic regression suggests older age, facility type, location, Hispanic, Asian, and Native American ethnicity were associated with nonoperative management. CONCLUSION: The vast majority of PTmC in the United States is treated with an operation. A small but significant increase in nonoperative management occurred between 2004-2010 and 2010-2015.

Parathyroidectomy is Safe in Elderly Patients: A National Surgical Quality Improvement Program Study.

BACKGROUND: With increasing age, the incidence of hyperparathyroidism is increased. This study evaluates parathyroidectomy outcomes in elderly patients. METHODS: Primary hyperparathyroidism patients having parathyroidectomy as listed in the 2005-2017 ACS-NSQIP database were separated by age: ≤60, 61-79 and ≥80. Outcomes included complications, 30-day mortality, return to the OR, operating times, and hospital length of stay (LOS). Multivariable logistic regression was used to compare patients 61-79 and ≥80 to those ≤60. Patients ≤60 and ≥80 were propensity score matched using gender, race, BMI, smoking status, steroid use, modified frailty index (mFI), ASA class, procedure, setting, anesthesia, and wound class. Morbidity and mortality were compared to ACS-NSQIP database patients having elective inguinal hernia repair. RESULTS: Of 47,701 patients: 22,220 were ≤60, 22,683 were 61-79, and 2798 were ≥80. Patients ≥80 had more complications (2.3% vs. 1.5% for 61-79 and 1.0% for ≤60, p < 0.01), LOS > 1 day (10.3% vs. 5.8% and 6.7%, p < 0.01), and mortality (0.21% vs. 0.11% and 0.03%, p < 0.01). On multivariable analysis of the overall population, older age, male gender, steroid use, high mFI, outpatient procedure, and general anesthesia increased the risk of complications. On propensity score matched analysis, there was no difference in complications (1.5% vs. 2.2%, p = 0.06) or mortality (0.04% vs. 0.23%, p = 0.12) between patients ≤60 and ≥80. Parathyroidectomy morbidity and mortality was lower than that for elective inguinal hernia repair in patients ≥80 (2.3% vs. 10% and 0.21% vs. 1.1%, p < 0.01). CONCLUSIONS: Parathyroidectomy is a safe operation, offering lower morbidity and mortality than elective hernia repair in all age groups including octogenarians.

Survival with Follicular and Hurthle Cell Microcarcinoma Compared to Papillary Thyroid Microcarcinoma: A Population Study of 84,532 Patients.

BACKGROUND: This study compares survival in patients with the rare subtypes of follicular (FTmC) and Hurthle cell (HCmC) microcarcinoma compared to that of papillary thyroid (PTmC) microcarcinoma. METHODS: Patients with FTmC and HCmC were selected from the National Cancer Database 2004-2015 and compared with PTmC. Patient clinicopathological characteristics and overall survival (OS) were analyzed. Multivariable logistic and Cox regression analysis evaluated binary outcomes and predictors of survival. A propensity score matched analysis using age, gender, race, extrathyroidal extension (ETE), nodal status, distant metastasis, radiation, and operation was performed to evaluate the difference in OS with FTmC, HCmC, and PTmC. RESULTS: We identified 858 FTmC, 476 HCmC, and 82,056 PTmC. FTmC was less likely to have macroscopic ETE compared to PTmC (2.6% vs. 3.1% p = 0.03), but more likely to have distant metastasis (2.3% vs. 0.2%, p < 0.01). FTmC and HCmC were less likely to have nodal metastasis (2.7%, 2.5% vs. 10.9%, p < 0.01). Ten-year OS was decreased in patients with FTmC (91.4%, p = 0.04) and HCmC (89.8%, p < 0.01) compared to PTmC (93.5%). On multivariable analysis, histology was not associated with OS. With HCmC, older age (OR 1.13, p < 0.01) and male gender (OR 2.72, p = 0.03) were associated with decreased OS. In propensity matched analysis, there was no difference in 10-year OS with FTmC and PTmC (91.4% vs. 93.7%, p = 0.54), but HCmC had decreased OS compared to PTmC (89.8% vs. 94.3%, p = 0.04). CONCLUSIONS: Patients with FTmC have comparable OS to those with PTmC, but HCmC has decreased OS especially in older and male patients.

Are we Overtreating Hormone Receptor Positive Breast Cancer with Neoadjuvant Chemotherapy? Role of OncotypeDx® for Hormone Receptor Positive Patients Undergoing Neoadjuvant Chemotherapy.

BACKGROUND: The utilization of OncotypeDx in the setting of neoadjuvant chemotherapy (NCT) is not well defined. The objective of this study was to determine what proportion of hormone receptor (HR)-positive patients undergoing NCT would not benefit from chemotherapy based on OncotypeDx recurrence scores (RS) and predictors of a high RS as defined by the TAILORx trial. METHODS: The National Cancer Data Base was used to identify patients with unilateral clinical stage I-III HR+/Her2- breast cancer who had an OncotypeDx score and who had undergone NCT. Patients undergoing adjuvant chemotherapy were used as a comparison group. RESULTS: Of 307,666 patients, 41.8% had testing with OncotypeDx. Of these, 76.6% had no chemotherapy, 22.3% adjuvant chemotherapy, and 1.1% NCT. OncotypeDx testing in NCT patients increased from 4.9% in 2010 to 8.2% in 2015. Of NCT patients with OncotypeDx testing, 11.6% had RS < 11, 44.4% RS 11-25, and 43.9% RS > 25. In patients age ≤ 50 years, 14.5% had RS < 11, 12.4% RS 11-15, 31.4% RS 16-25, and 41.7% RS > 25. Predictors of RS > 25 on multivariable analysis included grade 3 tumors (odds ratio [OR] 3.83) and PR-negative tumors (OR 5.26) but not clinical T or N stage (p > 0.05). CONCLUSIONS: More than half of patients with OncotypeDx testing are being overtreated with NCT, and a third of younger patients are being overtreated. Predictors of a high RS are reliably available at core biopsy, suggesting an application of OncotypeDx in determining the need for NCT for some HR-positive breast cancers.

Differences in the Impact of Age on Mortality in Well-Differentiated Thyroid Cancer.

INTRODUCTION: Well-differentiated thyroid cancer (WDTC) is unique in that patient age is part of staging. Several studies have shown a need to increase the age threshold in staging for WDTC, but the separate impact of age on prognosis for papillary and follicular carcinomas has not been examined. We hypothesize that age impacts survival differently for papillary and follicular carcinomas. METHODS: Patients with invasive papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma (FTC) between 2004 and 2013 were identified in the National Cancer Database, and were stratified by histologic type. Overall survival (OS) was analyzed using multivariable Cox regression, and the Youden index was used to find the optimal age threshold for both histologies. RESULTS: A total of 204,139 patients with WDTC were identified. Ninety-two percent had PTC, while 7.7% had FTC. The average age was 48.4 years and OS was 96.3%, with a median follow-up of 52.7 months. When analyzing age in 5-year increments, 10-year mortality increased incrementally by 30-50% per age group for PTC, from age < 35 to ≥ 70 years, without an obvious inflection point. However, FTC patients experienced a more than threefold increase in 10-year mortality from age 40-44 years (2.5%) to age 45-49 years (7.9%). The same pattern was found on multivariable Cox regression. The Youden index found the optimal age thresholds were 58.5 years for PTC and 46.2 years for FTC. CONCLUSION: OS for PTC decreases incrementally with age, but OS for FTC decreases significantly in patients aged 45 years and older. A higher age threshold may inappropriately downstage some high-risk follicular cancer patients.

Minimally Invasive Adrenalectomy for Adrenocortical Carcinoma: Five-Year Trends and Predictors of Conversion.

BACKGROUND: Adrenocortical carcinoma (ACC) is rare but often fatal. Surgery offers the only chance of cure. As minimally invasive (MI) procedures for cancer become common, their role for ACC is still debated. We reviewed usage of MI approaches for ACC over time and risk factors for conversion using a large national database. METHODS: ACC patients with localized disease were identified in the National Cancer Data Base from 2010 to 2014. A retrospective review examined trends in the surgical approach over time. Patient demographics, surgical approach, and tumor characteristics between MI, open, and converted procedures were compared. RESULTS: 588 patients underwent adrenalectomy for ACC, of which 200 were minimally invasive. From 2010 to 2014, MI operations increased from 26 to 44% with robotic procedures increasing from 5 to 16%. The use of MI operations compared to open was not different based on facility type (p = 0.40) or location (p = 0.63). MI tumors were more likely to be confined to the adrenal (p < 0.001) but final margin status was not different (p = 0.56). Conversion was performed in 38/200 (19%). Average tumor size was 10.2 cm in the converted group compared to 8.6 cm in the MI group (p = 0.09). There was no difference in extent of disease (p = 0.33), margin status (p = 0.12), or lymphovascular invasion (p = 0.59) between MI and converted procedures. Tumor size > 5 cm was the only significant predictor of conversion (p = 0.04). No patients with pathologic stage I disease required conversion (0/19). CONCLUSIONS: The frequency of MI approaches for ACC is increasing. In the final year of the study, 44% of adrenalectomies were MI. Size > 5 cm was the only significant predictor of conversion.

CONCORDANCE OF PRE-OPERATIVE CLINICAL STAGE WITH PATHOLOGIC STAGE IN PATIENTS ≥45 YEARS OLD WITH WELL-DIFFERENTIATED THYROID CANCER.

OBJECTIVE: Clinical stage (cStage) in thyroid cancer determines extent of surgical therapy and completeness of resection. Pathologic stage (pStage) is an important determinant of outcome. The rate of discordance between clinical and pathologic stage in thyroid cancer is unknown. METHODS: The National Cancer Data Base was queried to identify 27,473 patients ≥45 years old with cStage I through IV differentiated thyroid cancer undergoing surgery from 2008-2012. RESULTS: There were 16,286 (59.3%) cStage I patients; 4,825 (17.6%) cStage II; 4,329 (15.8%) cStage III; and 2,013 (7.3%) cStage IV patients. The upstage rate was 15.1%, and the downstage rate was 4.6%. For cStage II, there was a 25.5% upstage rate. The change in cStage was a result of inaccurate T-category in 40.8%, N-category in 36.3%, and both in 22.9%. On multivariate analysis, the patients more likely to be upstaged had papillary histology, tumors 2.1 to 4 cm, total thyroidectomy, nodal surgery, positive margins, or multifocal disease. Upstaged patients received radioiodine more frequently (75.3% vs. 48.1%; P<.001). CONCLUSION: Approximately 20% of cStage is discordant to pStage. Certain populations are at risk for inaccurate staging, including cT2 and cN0 patients. Upstaged patients are more likely to receive radioactive iodine therapy. ABBREVIATIONS: CI = confidence interval; cStage = clinical stage; DTC = differentiated thyroid cancer; NCDB = National Cancer Data Base; OR = odds ratio; pStage = pathologic stage; RAI = radioactive iodine.

The extent of vascular resection is associated with perioperative outcome in patients undergoing pancreaticoduodenectomy.

BACKGROUND: Few studies have examined the relation between extent of vascular resection and morbidity following pancreaticoduodenectomy (PD) with vein resection (PDVR). METHODS: Patients undergoing PD for malignancy were identified using the American College of Surgeons National Surgical Quality Improvement Project from 2006 to 2013. Current procedural terminology codes were used to characterize PDVR. RESULTS: 9235 patients underwent PD, 977 (10.6%) had PDVR - 640 with direct and 224 with graft repair. PDVR had longer operative times (456 ± 136 vs 374 ± 128 min, p < 0.05) and higher intraoperative transfusions (1.8 ± 3.4 vs 4.3 ± 4.9 units, p < 0.05) than PD alone. On adjusted multivariable regression, PDVR with either direct or graft repairs was associated with higher rates of overall morbidity (OR [odds ratio] 1.50 for direct, 1.74 for graft, p < 0.05), bleeding (OR 2.18 for direct, 3.26 for graft, p < 0.05), and DVT (OR 2.12 for direct, 2.62 for graft, p < 0.05) compared to PD alone. Graft repair was further associated with increased risk of reoperation (OR 1.59), septic shock (OR 2.77) and 30-day mortality (OR 2.72), all p < 0.05. DISCUSSION: The risk of significant morbidity and mortality for PDVR is associated with the extent of vascular resection, with graft repairs having increased morbidity and mortality rates.

Impact of an In-visit Decision Aid on Patient Knowledge about Contralateral Prophylactic Mastectomy: A Pilot Study.

BACKGROUND: Studies have reported that breast cancer patients have limited understanding about the oncologic outcomes following contralateral prophylactic mastectomy (CPM). We hypothesized that an in-visit decision aid (DA) would be associated with higher patient knowledge about the anticipated short and long term outcomes of CPM. METHODS: We piloted a DA which used the SCOPED: (Situation, Choices, Objectives, People, Evaluation and Decision) framework. Knowledge, dichotomized as "low" (≤3 correct) versus "high" (≥4 correct), was assessed immediately after the visit by a 5 item survey. There were 97 DA patients (response rate 62.2 %) and 114 usual care (UC) patients (response rate 71.3 %). RESULTS: Patient demographic factors were similar between the two groups. Twenty-one (21.7 %) patients in the DA group underwent CPM compared with 18 (15.8 %) in the UC group (p = 0.22). Mean and median knowledge levels were significantly higher in the DA group compared with the UC group for patients of all ages, tumor stage, race, family history, anxiety levels, worry about CBC, and surgery type. Eighty-six (78.9 %) of UC versus 35 (37.9 %) DA patients had low knowledge. Of patients who underwent CPM, 15 (83.3 %) in the UC cohort versus 5 (25.0 %) of DA patients had "low" knowledge. CONCLUSIONS: Knowledge was higher in the DA group. The UC group had approximately three times the number of patients of the DA group who were at risk for making a poorly informed decision to have CPM. Future studies should assess the impact of increased knowledge on overall CPM rates.

Post-mastectomy radiation therapy and overall survival after neoadjuvant chemotherapy.

BACKGROUND: The role of postmastectomy radiation therapy (PMRT) after neoadjuvant chemotherapy (NAC) and mastectomy is unclear, especially in patients that have post-treatment tumor negative axillary nodes (ypN0). METHODS: The National Cancer Data Base was used to identify women that had PMRT after NAC and mastectomy for clinically node positive (cN1-2) disease from 2004 to 2008. Median follow-up time was 69 months. RESULTS: 8,321 patients were included for analysis, and 6140 (65.6%) had cN1 disease and 2181 (23.3%) had cN2 disease. On adjusted survival analysis, PMRT was associated with an overall survival (OS) benefit in both patients with cN1 (5-yr OS 75.8% vs. 71.9%, P < 0.01) and cN2 (5-yr OS 69.2% vs. 58.6%, P < 0.01) disease. In the subgroup of patients that were ypN0 after NAC, there was no significant survival difference (P > 0.11) for PMRT compared to those patients who were not ypN0, except for patients with hormone-receptor negative tumors, who had improved OS with PMRT (HR 0.65, P < 0.01). CONCLUSIONS: PMRT is associated with improved OS in patients with cN1 and cN2 disease after NAC and mastectomy. However, in the subgroup of patients that were ypN0 after NAC, PMRT improved OS for hormone-receptor negative patients but not hormone-receptor positive patients.

Clinical accuracy of preoperative breast MRI for breast cancer.

BACKGROUND: It is unclear if breast magnetic resonance imaging (MRI) is more accurate than mammography (MGM) and ultrasound (U/S) in aggregate for patients with invasive cancer. METHODS: We compared concordance of combined tumor size and tumor foci between MRI and MGM and U/S combined to pathological tumor size and foci as the gold standard from 2009 to 2015. Tumor size was nonconcordant if it differed from the pathologic size by ≥33% and tumor foci was nonconcordant if >1 foci were seen. If one or both of the MGM or U/S was nonconcordant and the MRI was concordant, MRI provided greater accuracy. RESULTS: Of 471 patients with MGM, US, and MRI, MRI was more accurate for 32.9% of patients for tumor size and for 21.9% for tumor foci. Patients for whom MRI had greater accuracy were compared to those who did not for clinical and tumor factors. The only significant factor was calcifications on mammography. Tumor size, stage, molecular subtype, histology, grade, patient BMI, age, mammographic density, and use of hormone replacement therapy were not significantly different. CONCLUSIONS: Breast MRI provides greater accuracy for a third of patients undergoing preoperative MGM and U/S. Mammographic calcifications were associated with MRI clinical accuracy for patients with invasive cancer.

Are the ACOSOG Z0011 Trial Findings Being Applied to Breast Cancer Patients Undergoing Neoadjuvant Chemotherapy?

In 2010, the ACOSOG Z0011 trial showed equivalent survival and recurrence between sentinel lymph node biopsy (SLNB) alone versus axillary lymph node dissection (ALND) for those with a tumor positive sentinel node (SN). We examined national trends in axillary surgery following neoadjuvant chemotherapy (NAC) for clinically node positive disease in the years prior to and after the Z0011 trial publication. 12,063 women with cT1-4N1M0 invasive breast cancer who underwent NAC from 2006 to 2013 and had 1-3 positive nodes on pathology were selected from the National Cancer Data Base. We defined SLNB as 1-4 nodes and ALND as ≥10 nodes examined. 2,704 women (22.4%) underwent SLNB alone and 9,359 (77.6%) underwent ALND. The rate of SLNB increased from 25.6% in 2006 to 33.3% in 2012 in patients that underwent lumpectomy (p < 0.01) and increased from 20.6% to 22.8% in patients that underwent mastectomy (p = 0.25). Patients treated at Community centers (30.4% versus 19.2% at Academic centers) and those with less positive nodes (32.2% for 1 positive node versus 10.1% for 3 positive nodes, p < 0.01) were more likely to have SLNB alone compared to ALND. On multivariate analysis, treatment with lumpectomy (OR 1.46, CI 1.28-1.67), lower number of positive nodes (OR 3.98, CI 3.29-4.82) and lobular subtype (OR 1.82, CI 1.42-2.34) were independent predictors of receiving SLNB alone after NAC. Approximately 22% of patients with cN1 breast cancer underwent SLNB alone for pN1 disease after NAC. Ongoing clinical trials will determine if recurrence and survival rates are equivalent between SLNB and ALND groups.

Utilization of Axillary Surgery for Patients With Ductal Carcinoma In Situ: A Report From the National Cancer Data Base.

BACKGROUND: This study evaluated the use of axillary surgery (AS), including sentinel lymph node biopsy (SLNB), for patients with ductal carcinoma in situ (DCIS) and the factors associated with its use. To determine whether utilization of SLNB is appropriate, predictors of SLNB performance were compared with factors predictive of tumor upstaging. METHODS: The National Cancer Data Base was utilized to identify patients with American Joint Committee on Cancer (AJCC) clinical stage 0 breast cancer treated from 2004 to 2013. DCIS with microinvasion was excluded. Chi square tests and logistic regression were used to examine patient, tumor, and facility features associated with SLNB and tumor upstaging. RESULTS: Of the 218,945 total patients, 155,093 (70.8 %) underwent lumpectomy, and 63,852 (29.2 %) underwent mastectomy. SLNB was performed for 19.0 % of lumpectomy patients and 63.5 % of mastectomy patients. Multivariate analysis for 2012-2013 demonstrated that estrogen receptor (ER)-negative and grade 3 tumors were more likely to be treated with SLNB in both groups. Tumor size was significant only for the lumpectomy patients who underwent one operation. Further, 22.8 % of lumpectomy patients and 18.7 % of mastectomy patients who underwent AS were upstaged compared with 1.8 % of lumpectomy and 3.6 % of mastectomy patients who did not undergo AS. Tumor upstaging was predicted by ER-negative status (odds ratio [OR] 2.99; 95 % confidence interval [CI] 2.76-3.24) but not by higher grade or larger tumor size. CONCLUSIONS: Use of SLNB for DCIS is high with mastectomy, and nearly one fifth of the lumpectomy patients underwent SLNB. However, the performance of AS was strongly associated with the likelihood of upstaging in both groups, suggesting that surgical judgment plays an important role in this decision.

Patient satisfaction with nipple-sparing mastectomy: A prospective study of patient reported outcomes using the BREAST-Q.

BACKGROUND AND OBJECTIVES: The authors sought to study patient-reported outcomes following nipple-sparing mastectomy (NSM). METHODS: From 2008 to 2011, the BREAST-Q was administered to women undergoing NSM surgery for cancer treatment or risk-reduction prior to surgery and at 2 years after completion of reconstruction. The change in score over time and the impact of surgical indication, complication occurrence, and laterality on scores were analyzed. RESULTS: The BREAST-Q was prospectively administered to 39 women undergoing NSM for cancer treatment (n = 17) or risk-reduction (RR) (n = 22). At 2 years after operation, median overall satisfaction with breasts was 75 (IQR = 67,100). There were significant postoperative increases in scores for overall satisfaction with breasts (+8, P = 0.021) and psychosocial well-being (+14, P = 0.003). Postoperatively, RR patients had significantly higher scores for psychosocial wellness, physical impact (chest), and overall satisfaction with outcome compared to cancer treatment patients (P < 0.05). Also, increase from preoperative to postoperative psychosocial wellness was higher in the RR compared to cancer treatment patients (+17 vs. +1, P = 0.043). Complication occurrence did not significantly impact postoperative scores. CONCLUSIONS: Following NSM for cancer treatment or RR, patients demonstrated high levels of satisfaction and quality of life as measured by BREAST-Q. Satisfaction level increased 2 years following operation. J. Surg. Oncol. 2016;114:416-422. © 2016 Wiley Periodicals, Inc.

TIMING OF RADIOACTIVE IODINE THERAPY DOES NOT IMPACT OVERALL SURVIVAL IN HIGH-RISK PAPILLARY THYROID CARCINOMA.

OBJECTIVE: Postthyroidectomy radioiodine (RAI) therapy is indicated for papillary thyroid carcinoma (PTC) with high-risk features. There is variability in the timing of RAI therapy with no consensus. We analyzed the impact of the timing of initial RAI therapy on overall survival (OS) in PTC. METHODS: The National Cancer Data Base (NCDB) was queried from 2003 to 2006 for patients with PTC undergoing near/subtotal or total thyroidectomy and RAI therapy. High-risk patients had tumors >4 cm in size, lymph node involvement, or grossly positive margins. Early RAI was ≤3 months, whereas delayed was between 3 and 12 months after thyroidectomy. Kaplan-Meier (KM) and Cox survival analyses were performed after adjusting for patient and tumor-related variables. A propensity-matched set of high-risk patients after eliminating bias in RAI timing was also analyzed. RESULTS: There were 9,706 patients in the high-risk group. The median survival was 74.7 months. KM analysis showed a survival benefit for early RAI in high-risk patients (P = .025). However, this difference disappeared (hazard ratio [HR] 1.26, 95% confidence interval [CI] 0.98-1.62, P = .07) on adjusted Cox multivariable analysis. Timing of RAI therapy failed to affect OS in propensity-matched high-risk patients (HR 1.09, 95% CI 0.75-1.58, P = .662). CONCLUSION: The timing of postthyroidectomy initial RAI therapy does not affect OS in patients with high-risk PTC.

Survival Outcomes and Pathologic Features Among Breast Cancer Patients Who Have Developed a Contralateral Breast Cancer.

BACKGROUND: Studies have shown that contralateral breast cancer (CBC) portends worse survival compared to unilateral breast cancer (UBC), but few studies have been conducted in the United States, and survival is usually examined from the time of CBC development. METHODS: Utilizing the Surveillance, Epidemiology, and End Results database, we selected 83,001 newly diagnosed breast cancer patients from 1998 to 2005. The time interval between the initial cancer and CBC was used as a time-dependent variable in a Cox regression analysis to examine overall survival (OS) and disease-specific survival (DSS) between UBC and CBC. RESULTS: Overall, 2130 patients (2.6 %) developed a CBC, 47.2 % within 5 years and 52.8 % ≥ 5 years. Most stage I patients (61.9 %) developed a stage I CBC, and a majority of stage II patients (51.6 %) developed a stage I CBC (p < 0.001). There was a median follow-up of 8.7 years. After adjustment, patients who developed a CBC 4 years after their initial breast cancer had worse DSS compared to patients with UBC (hazard ratio 1.36, 95 % confidence interval 1.03-1.79). Those patients who developed their CBC 8 years after their initial breast cancer had improved DSS (hazard ratio 0.37, 95 % confidence interval 0.20-0.67). Similar trends were observed for OS. Similar trends for OS and DSS were observed for estrogen receptor-negative women and women <50 years old. CONCLUSIONS: Development of a CBC early is associated with worse survival, but CBC development later on is associated with improved survival. Future studies are needed that can assist physicians with how to predict whether a patient will develop a CBC early on.

Wait times for breast surgical operations, 2003-2011: a report from the National Cancer Data Base.

BACKGROUND: Few large-scale multicenter studies have examined wait times for breast surgery and no benchmarks exist. METHODS: Using the National Cancer Data Base, we analyzed time from diagnosis to first surgery for 819,175 non-neoadjuvant AJCC stage 0-III breast cancer patients treated from 2003 to 2011. Chi-square tests and logistic regression models were used to examine factors associated with delays to surgery and adjuvant chemotherapy. RESULTS: Seventy percent of patients underwent an initial lumpectomy (LP), 22% a mastectomy (MA), and 8% a mastectomy with reconstruction (MR). The median time from diagnosis to first surgery significantly increased by approximately 1 week for all three procedures over the study period. In a multivariate analysis, the following variables were independent predictors of a longer wait time to first surgery: increasing age, black or Hispanic race, Medicaid or no insurance, low-education communities and metropolitan areas, increasing comorbidities, stage 0 and grade 1 disease, academic/research facilities, high-volume facilities, and facilities located in the New England, Mid-Atlantic, and Pacific regions. In 2010-2011, patients who waited >30 days for surgery were 1.36 times more likely (OR = 1.36, 95% CI 1.30-1.43) to experience a delay to adjuvant chemotherapy >60 days compared with patients who were surgically treated within 30 days of diagnosis. CONCLUSIONS: Facility and socioeconomic factors are most strongly associated with longer wait times for breast operations, and delays to surgery are associated with delays to adjuvant chemotherapy initiation.
