RESUMO
INTRODUCTION: Quality of surgical care is understudied for lobular inflammatory breast cancer (IBC), which is less common, more chemotherapy-resistant, and more mammographically occult than ductal IBC. We compared guideline-concordant surgery (modified radical mastectomy [MRM] without immediate reconstruction following chemotherapy) for lobular versus ductal IBC. METHODS: Female individuals with cT4dM0 lobular and ductal IBC were identified in the National Cancer Database (NCDB) from 2010-2019. Modified radical mastectomy receipt was identified via codes for "modified radical mastectomy" or "mastectomy" and "≥10 lymph nodes removed" (proxy for axillary lymph node dissection). Descriptive statistics, chi-square tests, and t-tests were used. RESULTS: A total of 1456 lobular and 10,445 ductal IBC patients were identified; 599 (41.1%) with lobular and 4859 (46.5%) with ductal IBC underwent MRMs (p = 0.001). Patients with lobular IBC included a higher proportion of individuals with cN0 disease (20.5% lobular vs. 13.7% ductal) and no lymph nodes examined at surgery (31.2% vs. 24.5%) but were less likely to be node-negative at surgery (12.7% vs. 17.1%, all p < 0.001). Among those who had lymph nodes removed at surgery, patients with lobular IBC also had fewer lymph nodes excised versus patients with ductal IBC (median [interquartile range], 7 (0-15) vs. 9 (0-17), p = 0.001). CONCLUSIONS: Lobular IBC patients were more likely to present with node-negative disease and less likely to be node-negative at surgery, despite having fewer, and more frequently no, lymph nodes examined versus ductal IBC patients. Future studies should investigate whether these treatment disparities are because of surgical approach, pathologic assessment, and/or data quality as captured in the NCDB.

BACKGROUND: Cryoablation is a well-established technique to treat fibroadenomas. Pilot studies suggest this could be an effective non-surgical treatment for breast cancer. American College of Surgeons Oncology Group Z1072 is a phase II trial exploring the effectiveness of cryoablation in the treatment of breast cancers. METHODS: The primary endpoint of Z1072 was the rate of complete tumor ablation, defined as no remaining invasive breast cancer (IBC) or ductal carcinoma in situ (DCIS) on pathologic examination of the targeted lesion. A secondary objective was to evaluate the negative predictive value of magnetic resonance imaging (MRI) to determine residual IBC or DCIS. Eligible patients included those with unifocal invasive ductal breast cancer ≤2 cm, with <25 % intraductal component and tumor enhancement on MRI. A total of 19 centers contributed 99 patients, of which 86 patients (87 breast cancers) were evaluable for data analysis. RESULTS: Final pathology results, regardless of whether residual IBC/DCIS was in the targeted ablation zone or elsewhere in the breast, showed successful ablation in 66/87 (75.9 %) cancers. The 90 % confidence interval for the estimate of successful cryoablation was 67.1-83.2, with the one-sided lower-sided 90 % CI of 69.0. The negative predictive value of MRI was 81.2 % (90 % CI 71.4-88.8). When multifocal disease outside of the targeted cryoablation zone was not defined as an ablation failure, 80/87 (92 %) of the treated cancers had a successful cryoablation. CONCLUSION: Further studies with modifications on the Z1072 protocol could be considered to evaluate the role for cryoablation as a non-surgical treatment of early-stage breast cancer.

BACKGROUND: Society of Surgical Oncology (SSO)-approved fellowships in Breast Oncology began training fellows in 2004. Here we ascertain methods of evaluating and improving the fellowship experience through fellowship alumni experience. METHODS: We conducted an electronic survey of fellowship graduates to learn perceived successes and weaknesses of their fellowship training, as well as their current practice experiences. Our electronic survey focused on their preparedness for practice, their job opportunities, and their use of image-guided biopsies in practice. RESULTS: Between 2005 and 2009, 142 fellows graduated and received our survey; 85 (60%) responded. Although 98% of graduates though that they were well prepared by their fellowship for performing breast cancer surgery, fewer thought that they were well prepared to perform oncoplastic techniques (53%), ultrasound (39%), and ultrasound-guided biopsies (28%). Nevertheless, many acquired additional training, and 63% were performing ultrasound-guided biopsies in practice. The majority (76%) were performing breast surgery exclusively, with 14% identifying themselves as director of a breast center and only 29% describing themselves as being in private practice-the rest being employed at a hospital or university. Only 8% of respondents were disappointed with the job market, and 67% stated they had received at least three job offers; 82% were satisfied in their current job. CONCLUSIONS: SSO breast oncology fellowships appear to be training confident, well-prepared graduates with good job outlooks, and many are achieving leadership positions. Deficiencies in sonography training, some advanced surgical techniques, and administrative experiences should be addressed by program directors as graduates do perceive the need for such training.

During the past decade, increasing emphasis has been placed on defining and measuring the quality of health care delivery. The Outcomes Committee of the Society of Surgical Oncology (SSO) was established in 2008 to explore and promote emerging outcomes-related topics that are most relevant to society membership. In recognition of the importance of health care quality, a mini-symposium was held at the SSO's 63rd Annual Cancer Symposium in St. Louis, Missouri, in March 2010. The primary objective of the symposium was to define what constitutes quality measurement in cancer care. This article presents an overview of the symposium proceedings.

Risk assessment evaluation and breast cancer (BRCA) testing can occur in situations where a woman considers herself to be at increased risk for developing breast cancer or her physicians, either during routine evaluation or after diagnosis of unilateral breast cancer, consider her to be at risk for harboring a genetic predisposition to breast malignancy. This study examined the impact of risk assessment counseling on trends in breast surgery and cost of care. A retrospective chart review was performed from January 1, 1999 to December 31, 2008 for women older than 18 years who underwent breast surgery for malignancy or prophylaxis, had at least 1-year follow-up, and underwent genetic counseling. From the total number of women treated at our institution who underwent unilateral or bilateral mastectomy, we identified 102 women who underwent genetic counseling and selected 199 patients who did not undergo counseling to create a 4:1 retrospective case-control study. Patients who underwent BRCA gene testing and/or counseling were compared with patients who did not (controls). The study was powered at 70%, and alpha was set at 0.05. Counseled patients were >9 times more likely to undergo bilateral mastectomies (odds ratio = 9.18). They were younger (46.4 vs. 61.8) and incurred higher total costs ($10,810 vs. $7,266) (P < 0.002). The same trend was observed in each group. In counseled and control groups, younger women chose bilateral mastectomies (mean 44.4; 55.5), whereas older women chose unilateral procedures (mean 49.8; 63.02) (P < 0.014). Total cost for bilateral mastectomies was greater than unilateral mastectomies for both groups. Of 55 counseled patients undergoing mastectomies (85 breasts), 78 (92%) breasts were reconstructed, whereas 113 (49%) of 230 breasts were reconstructed in the control group. There was a statistically significant association between counseling with BRCA testing and decision to undergo bilateral as opposed to unilateral mastectomies. Younger women were also more likely to choose bilateral mastectomies whether or not they underwent counseling. Furthermore, a greater proportion of counseled women who underwent reconstruction opted to have bilateral implants. At our institution, younger women tend to choose costlier options.

BACKGROUND: A recent trend in health care is to integrate palliative care (PC) programs across multiple hospitals to reduce variation, improve quality, and reduce cost. OBJECTIVE: The study objective was to demonstrate the benefits of PC for a system. METHODS: The study was a descriptive study using retrospective medical records in seven federated hospitals where PC developed differently before system integration. Measured were length of stay (LOS), mortality, readmissions, saved intensive care unit (ICU) days, cost avoidance, and hospice referrals. RESULTS: PC services within the first 48 hours of admission demonstrate a shorter LOS (5.08 days), reduced costs 40% ($2,362 per day), and decreased mortality (1.01 versus 1.10) for one hospital. Readmissions at 30, 60, and 90 days after a PC consult decreased (61.5%, 47.0%, and 42.1%, respectively). Annual pre- and postprogram referrals to hospice increased (65 to 107). Using modified matched pairs, LOS of PC patients seen within 48 hours of admission average 1.67 days less compared to non-PC patients. LOS for ICU patients with PC services in the ICU within the first 48 hours decreased by 1.12 days. Overall cost avoidance was 1.5 times total cost for PC programs systemwide. One pilot project using a full-time physician in the ICU reduced cost more than $600,000, with 315 saved ICU days, annualized. Systemwide, 69.3% of all referrals to hospice were made by the PC service. CONCLUSION: Early involvement of PC services emerged as advantageous to the net benefit. Given that health care's changing landscape will increasingly include bundled payment and risk holding strategies to improve quality and reduce cost in health care systems, systemwide PC will play a vital role.

PURPOSE: To determine whether exercise training would increase lymphocyte activation in patients with breast cancer following chemotherapy. Activation was determined by the presence of CD4(+)CD69(+) T-helper lymphocytes, mitogen-induced proliferation, and levels of cytokines produced by mitogen-stimulated lymphocytes and in the patients' plasma. METHODS: Patients with breast cancer (N = 28) who participated in a 6-month exercise program were compared with patients (N = 21) who did not exercise. Following chemotherapy, and 3 and 6 months later, patients underwent fitness evaluations and had blood drawn. The exercise program consisted of resistance training and aerobic activity at 60-75% functional capacity three times a week with a personal trainer. Immunochemistry and flow cytometry were used to measure the number of CD4(+)CD69(+) blood lymphocytes. Whole blood was stimulated with concanavalin A (ConA), phytohemagglutin (PHA), or pokeweed mitogen (PWM) to determine proliferation potential. Enzyme-linked immunosorbent assays (ELISA) were used to determine the concentration of interferon-gamma (IFN-gamma) and interleukin-6 (IL-6) in the culture medium of mitogen-stimulated lymphocytes as well as the plasma concentrations of IL-6, soluble IL-6 receptor, soluble gp130, and IFN-gamma. Analysis of groups across time was done using the Wilcoxon signed rank test, and comparisons of groups were done using the Mann-Whitney U test. RESULTS: The exercising patients showed increases in maximal oxygen uptake and upper body strength. This group also showed a greater percentage of CD4(+)CD69(+) cells and a greater level of tritiated thymidine incorporation (DNA synthesis) when stimulated with ConA, PHA, and PWM at the end of the intervention. Plasma and mitogen-stimulated IL-6 and IFN-gamma production were similar in both groups. CONCLUSION: Exercise may improve immune function by increasing lymphocyte activation in patients with breast cancer following treatment.

In the USA, 80% of patients with breast cancer are treated by community breast surgeons. NCDB data indicate that there are only small differences in outcomes between lower volume cancer programs and higher volume programs. There is some evidence that breast cancer patients of high-volume breast focused surgeons may have improved outcomes. This article discusses the challenges community breast surgeons face and some ways that the quality of care could be monitored and improved. Quality reporting programs of the Commission on Cancer and Mastery of Breast Surgery Program of the American Society of Breast Surgeons are recommended as tools to track and improve outcomes in breast cancer care.

A 37-year-old who underwent splenectomy for motor vehicle accident-related injuries was diagnosed with stage IIA carcinoma of left breast 12 years later. She underwent bilateral mastectomy and bilateral immediate unipedicle TRAM flap reconstruction. Her preoperative platelet counts ranged from 332 to 424 K/cmm. Intraoperative fluorescein confirmed mastectomy flap viability. On postoperative day 1, platelet count was 374 K/cmm and all suture lines appeared benign. The patient was discharged 3 days later with healthy appearing tram flaps and slight epidermolysis in the abdominal region. Over the next 2 weeks, both the mastectomy flaps and the abdominal region underwent progressive necrosis as the platelet count increased to 1390 K/cmm. Aspirin therapy was instituted at this time. The TRAM flaps remained completely viable. Eighteen days later, the patient required wound debridement with secondary closure of the breast wounds. Platelet count peaked at 1689 K/cmm 2 days later (postoperative day 38). The wounds deteriorated again and were managed conservatively. Two months after mastectomy, the first area of spontaneous healing was documented (platelet count 758 K/cmm). Ultimately, wounds healed as platelet count reached its preoperative baseline. We hypothesize that an abnormal secondary thrombocytosis at subdermal plexus level caused problematic healing in this patient's mastectomy and abdominal flaps.
