Global Cancer Surgery: pragmatic solutions to improve cancer surgery outcomes worldwide.

The first Lancet Oncology Commission on Global Cancer Surgery was published in 2015 and serves as a landmark paper in the field of cancer surgery. The Commission highlighted the burden of cancer and the importance of cancer surgery, while documenting the many inadequacies in the ability to deliver safe, timely, and affordable cancer surgical care. This Commission builds on the first Commission by focusing on solutions and actions to improve access to cancer surgery globally, developed by drawing upon the expertise from cancer surgery leaders across the world. We present solution frameworks in nine domains that can improve access to cancer surgery. These nine domains were refined to identify solutions specific to the six WHO regions. On the basis of these solutions, we developed eight actions to propel essential improvements in the global capacity for cancer surgery. Our initiatives are broad in scope, pragmatic, affordable, and contextually applicable, and aimed at cancer surgeons as well as leaders, administrators, elected officials, and health policy advocates. We envision that the solutions and actions contained within the Commission will address inequities and promote safe, timely, and affordable cancer surgery for every patient, regardless of their socioeconomic status or geographic location.

Cancer in sub-Saharan Africa: a Lancet Oncology Commission.

In sub-Saharan Africa (SSA), urgent action is needed to curb a growing crisis in cancer incidence and mortality. Without rapid interventions, data estimates show a major increase in cancer mortality from 520 348 in 2020 to about 1 million deaths per year by 2030. Here, we detail the state of cancer in SSA, recommend key actions on the basis of analysis, and highlight case studies and successful models that can be emulated, adapted, or improved across the region to reduce the growing cancer crises. Recommended actions begin with the need to develop or update national cancer control plans in each country. Plans must include childhood cancer plans, managing comorbidities such as HIV and malnutrition, a reliable and predictable supply of medication, and the provision of psychosocial, supportive, and palliative care. Plans should also engage traditional, complementary, and alternative medical practices employed by more than 80% of SSA populations and pathways to reduce missed diagnoses and late referrals. More substantial investment is needed in developing cancer registries and cancer diagnostics for core cancer tests. We show that investments in, and increased adoption of, some approaches used during the COVID-19 pandemic, such as hypofractionated radiotherapy and telehealth, can substantially increase access to cancer care in Africa, accelerate cancer prevention and control efforts, increase survival, and save billions of US dollars over the next decade. The involvement of African First Ladies in cancer prevention efforts represents one practical approach that should be amplified across SSA. Moreover, investments in workforce training are crucial to prevent millions of avoidable deaths by 2030. We present a framework that can be used to strategically plan cancer research enhancement in SSA, with investments in research that can produce a return on investment and help drive policy and effective collaborations. Expansion of universal health coverage to incorporate cancer into essential benefits packages is also vital. Implementation of the recommended actions in this Commission will be crucial for reducing the growing cancer crises in SSA and achieving political commitments to the UN Sustainable Development Goals to reduce premature mortality from non-communicable diseases by a third by 2030.

Racial Disparities in Time to Treatment Persist in the Setting of a Comprehensive Breast Center.

BACKGROUND: Racial disparities in breast cancer care have been linked to treatment delays. We explored whether receiving care at a comprehensive breast center could mitigate disparities in time to treatment. METHODS: Retrospective chart review identified breast cancer patients who underwent surgery from 2012 to 2018 at a comprehensive breast center. Time-to-treatment intervals were compared among self-identified racial and ethnic groups by negative binomial regression models. RESULTS: Overall, 2094 women met the inclusion criteria: 1242 (59%) White, 262 (13%) Black, 302 (14%) Hispanic, 105 (5%) Asian, and 183 (9%) other race or ethnicity. Black and Hispanic patients more often had Medicaid insurance, higher American Society of Anesthesiologists (ASA) scores, advanced-stage breast cancer, mastectomy, and additional imaging after breast center presentation (p < 0.05). After controlling for other variables, racial or ethnic minority groups had consistently longer intervals to treatment, with Black women experiencing the greatest disparity (incidence rate ratio 1.42). Time from initial comprehensive breast center visit to treatment was also significantly shorter in White patients versus non-White patients (p < 0.0001). Black race, Medicaid insurance/being uninsured, older age, earlier stage, higher ASA score, undergoing mastectomy, having reconstruction, and requiring additional pretreatment work-up were associated with a longer time from initial visit at the comprehensive breast center to treatment on multivariable analysis (p < 0.05). CONCLUSION: Racial or ethnic minority groups have significant delays in treatment even when receiving care at a comprehensive breast center. Influential factors include insurance delays and necessity of additional pretreatment work-up. Specific policies are needed to address system barriers in treatment access.

Contemporary management of breast cancer in Nigeria: Insights from an institutional database.

High-quality data are needed to guide interventions aimed at improving breast cancer outcomes in sub-Saharan Africa. We present data from an institutional breast cancer database to create a framework for cancer policy and development in Nigeria. An institutional database was queried for consecutive patients diagnosed with breast cancer between January 2010 and December 2018. Sociodemographic, diagnostic, histopathologic, treatment and outcome variables were analyzed. Of 607 patients, there were 597 females with a mean age of 49.8 ± 12.2 years. Most patients presented with a palpable mass (97%) and advanced disease (80.2% ≥ Stage III). Immunohistochemistry was performed on 21.6% (131/607) of specimens. Forty percent were estrogen receptor positive, 32.8% were positive for HER-2 and 43.5% were triple negative. Surgery was performed on 49.9% (303/607) of patients, while 72% received chemotherapy and 7.9% had radiotherapy. At a median follow-up period of 20.5 months, the overall survival was 43.6% (95% CI -37.7 to 49.5). Among patients with resectable disease, 18.8% (57/303) experienced a recurrence. Survival was significantly better for early-stage disease (I and II) compared to late-stage disease (III or IV) (78.6% vs 33.3%, P < .001). Receipt of adjuvant radiotherapy after systemic chemotherapy was associated with improved survival in patients with locally advanced disease (68.5%, CI -46.3 to 86 vs 51%, CI 38.6 to 61.9, P < .001). This large cohort highlights the dual burden of advanced disease and inadequate access to comprehensive breast cancer care in Nigeria. There is a significant potential for improving outcomes by promoting early diagnosis and facilitating access to multimodality treatment.

Geospatial access predicts cancer stage at presentation and outcomes for patients with breast cancer in southwest Nigeria: A population-based study.

BACKGROUND: The majority of women in Nigeria present with advanced-stage breast cancer. To address the role of geospatial access, we constructed a geographic information-system-based model to evaluate the relationship between modeled travel time, stage at presentation, and overall survival among patients with breast cancer in Nigeria. METHODS: Consecutive patients were identified from a single-institution, prospective breast cancer database (May 2009-January 2019). Patients were geographically located, and travel time to the hospital was generated using a cost-distance model that utilized open-source data. The relationships between travel time, stage at presentation, and overall survival were evaluated with logistic regression and survival analyses. Models were adjusted for age, level of education, and socioeconomic status. RESULTS: From 635 patients, 609 were successfully geographically located. The median age of the cohort was 49 years (interquartile range [IQR], 40-58 years); 84% presented with ≥stage III disease. Overall, 46.5% underwent surgery; 70.8% received systemic chemotherapy. The median estimated travel time for the cohort was 45 minutes (IQR, 7.9-79.3 minutes). Patients in the highest travel-time quintile had a 2.8-fold increase in the odds of presenting with stage III or IV disease relative to patients in the lowest travel-time quintile (P = .006). Travel time ≥30 minutes was associated with an increased risk of death (HR, 1.65; P = .004). CONCLUSIONS: Geospatial access to a tertiary care facility is independently associated with stage at presentation and overall survival among patients with breast cancer in Nigeria. Addressing disparities in access will be essential to ensure the development of an equitable health policy.

Opportunities for Improvement in the Administration of Neoadjuvant Chemotherapy for T4 Breast Cancer: A Comparison of the U.S. and Nigeria.

BACKGROUND: Neoadjuvant chemotherapy (NAC) is an integral component of T4 breast cancer (BCa) treatment. We compared response to NAC for T4 BCa in the U.S. and Nigeria to direct future interventions. MATERIALS AND METHODS: Cross-sectional retrospective analysis included all patients with non-metastatic T4 BCa treated from 2010 to 2016 at Memorial Sloan Kettering Cancer Center (New York, New York) and Obafemi Awolowo University Teaching Hospitals Complex (Ile Ife, Nigeria). Pathologic complete response (pCR) and survival were compared and factors contributing to disparities evaluated. RESULTS: Three hundred and eight patients met inclusion criteria: 157 (51%) in the U.S. and 151 (49%) in Nigeria. All U.S. patients received NAC and surgery compared with 93 (62%) Nigerian patients. Fifty-six out of ninety-three (60%) Nigerian patients completed their prescribed course of NAC. In Nigeria, older age and higher socioeconomic status were associated with treatment receipt. Fewer patients in Nigeria had immunohistochemistry performed (100% U.S. vs. 18% Nigeria). Of those with available receptor subtype, 18% (28/157) of U.S. patients were triple negative versus 39% (9/23) of Nigerian patients. Overall pCR was seen in 27% (42/155) of U.S. patients and 5% (4/76) of Nigerian patients. Five-year survival was significantly shorter in Nigeria versus the U.S. (61% vs. 72%). However, among the subset of patients who received multimodality therapy, including NAC and surgery with curative intent, 5-year survival (67% vs. 72%) and 5-year recurrence-free survival (48% vs. 61%) did not significantly differ between countries. CONCLUSION: Addressing health system, socioeconomic, and psychosocial barriers is necessary for administration of complete NAC to improve BCa outcomes in Nigeria. IMPLICATIONS FOR PRACTICE: This cross-sectional retrospective analysis of patients with T4 breast cancer in Nigeria and the U.S. found a significant difference in pathologic complete response to neoadjuvant chemotherapy (5% Nigeria vs. 27% U.S.). Five-year survival was shorter in Nigeria, but in patients receiving multimodality treatment, including neoadjuvant chemotherapy and surgery with curative intent, 5-year overall and recurrence-free survival did not differ between countries. Capacity-building efforts in Nigeria should focus on access to pathology services to direct systemic therapy and promoting receipt of complete chemotherapy to improve outcomes.

Adoption of SSO-ASTRO Margin Guidelines for Ductal Carcinoma in Situ: What Is the Impact on Use of Additional Surgery?

BACKGROUND: Historically, more than one-third of patients with ductal carcinoma in situ (DCIS) treated with breast-conserving surgery (BCS) underwent additional surgery. The SSO-ASTRO guidelines advise 2 mm margins for patients with DCIS having BCS and whole-breast radiation (WBRT). Here we examine guideline impact on additional surgery and factors associated with re-excision. PATIENTS AND METHODS: Patients treated with BCS for pure DCIS from August 2015 to January 2018 were identified. Guidelines were adopted on September 1, 2016, and all patients had separately submitted cavity-shave margins. Clinicopathologic characteristics, margin status, and rates of additional surgery were examined. RESULTS: Among 650 patients with DCIS who attempted BCS, 50 (8%) converted to mastectomy. Of 600 who had BCS as final surgery, 336 (56%) received WBRT and comprised our study group. One hundred twenty-eight (38%) were treated pre-guideline and 208 (62%) were treated post-guideline. Characteristics and margin status were similar between groups. The re-excision rate was 38% pre-guideline adoption and 29% post-guideline adoption (p = 0.09), with 91% having only one re-excision. Re-excision for ≥ 2 mm margins was uncommon (6% pre-guideline vs. 5% post-guideline). On multivariate analysis, younger age (OR 0.97, 95% CI 0.94-0.99, p = 0.02) and larger DCIS size (OR 1.43, 95% CI 1.2-1.8, p < 0.001) were predictive of re-excision; guideline era was not. Younger age (OR 0.93, 95% CI 0.9-0.97, p < 0.001) and larger size (OR 1.64, 95% CI 1.3-2.1, p < 0.001) were predictive of conversion to mastectomy, but residual tumor burden was low. CONCLUSIONS: The SSO-ASTRO guidelines did not significantly change re-excision rates for DCIS in our practice, likely since re-excision for margins ≥ 2 mm was uncommon even prior to guideline adoption, dissimilar to historically observed variations in surgeon practices. Younger age and larger DCIS size were associated with additional surgery.

Breast cancer early detection: A phased approach to implementation.

When breast cancer is detected and treated early, the chances of survival are very high. However, women in many settings face complex barriers to early detection, including social, economic, geographic, and other interrelated factors, which can limit their access to timely, affordable, and effective breast health care services. Previously, the Breast Health Global Initiative (BHGI) developed resource-stratified guidelines for the early detection and diagnosis of breast cancer. In this consensus article from the sixth BHGI Global Summit held in October 2018, the authors describe phases of early detection program development, beginning with management strategies required for the diagnosis of clinically detectable disease based on awareness education and technical training, history and physical examination, and accurate tissue diagnosis. The core issues address include finance and governance, which pertain to successful planning, implementation, and the iterative process of program improvement and are needed for a breast cancer early detection program to succeed in any resource setting. Examples are presented of implementation, process, and clinical outcome metrics that assist in program implementation monitoring. Country case examples are presented to highlight the challenges and opportunities of implementing successful breast cancer early detection programs, and the complex interplay of barriers and facilitators to achieving early detection for breast cancer in real-world settings are considered.

A Comparison of Patient-Reported Outcomes After Breast-Conserving Surgery and Mastectomy with Implant Breast Reconstruction.

BACKGROUND: Many factors influence decisions regarding choice of breast-conserving surgery (BCS) versus mastectomy with reconstruction for early invasive breast cancer. The purpose of this study was to compare patient satisfaction following BCS and mastectomy with implant reconstruction (M-iR) utilizing the BREAST-Q patient-reported outcome measure. METHODS: Women with stage I or II breast cancer undergoing BCS or M-iR who completed a BREAST-Q from 2010 to 2016 were identified by retrospective review of a prospective database. Baseline characteristics were compared, and linear mixed models were used to analyze associations with BREAST-Q scores over time. RESULTS: Our study group was composed of 3233 women; 2026 (63%) had BCS, 123 (3.8%) had nipple-sparing mastectomy, and 1084 (34%) had skin-sparing or total mastectomy. Median time from surgery to BREAST-Q was 205 days for BCS and 639 days for M-iR (p < 0.001). Regardless of type of surgery, breast satisfaction scores decreased significantly over time (p < 0.001), whereas psychosocial (p = 0.001) and sexual (p = 0.004) well-being scores increased significantly over time. BCS was associated with significantly higher scores over time compared with M-iR across all subscales (all p < 0.001). Radiation was significantly associated with decreased scores over time across all subscales (all p < 0.05). CONCLUSIONS: Breast satisfaction and quality-of-life scores were higher for BCS compared with M-iR in early-stage invasive breast cancer. These findings may help in counseling women who have a choice for surgical treatment. Breast satisfaction scores decreased over time in all women, highlighting the need for further evaluation with longer follow-up.

Does nonmetastatic inflammatory breast cancer have a worse prognosis than other nonmetastatic T4 cancers?

BACKGROUND: Both patients with inflammatory breast cancer (IFLBC) and patients with noninflammatory T4 breast cancer (non-IFLBC) have a heavy disease burden in the breast; whether the unique biology of IFLBC conveys a higher locoregional recurrence (LRR) risk and worse outcomes in comparison with other T4 lesions is uncertain. Here the outcomes of patients with IFLBC and patients with non-IFLBC treated with modern multimodality therapy are compared. METHODS: Patients with nonmetastatic T4 breast cancer treated with neoadjuvant chemotherapy, mastectomy, and radiation therapy between 2006 and 2016 were identified. Recurrences and survival were compared between patients with IFLBC and patients with non-IFLBC overall and stratified by receptor subtype. RESULTS: For 199 T4 patients, the median age was 52 years, and the median clinical tumor size was 7 cm. One hundred seventeen (59%) had IFLBC. With a median follow-up of 41 months, 4 patients had isolated LRR; all cases occurred in patients with IFLBC. The 5-year isolated LRR rate for patients with IFLBC was 4.8%. Overall, 14 patients had both LRR and distant recurrence (DR); 47 had DR only. The 5-year distant recurrence-free survival (DRFS) rates were similar for patients with IFLBC and patients with non-IFLBC (63% vs 71%; log-rank P = .14). The 5-year DRFS rate was lowest among triple-negative (TN) patients (43%) and was significantly lower for patients with TN IFLBC versus patients with non-IFLBC (28% vs 62%; log-rank P = .02). The 5-year overall survival rates (71% vs 74%; log-rank P = .4) and cancer-specific survival rates (74% vs 79%; log-rank P = .23) did not differ between IFLBC and non-IFLBC. CONCLUSIONS: Although IFLBC is often considered a unique biologic subtype, patients with IFLBC and patients with non-IFLBC had similar outcomes with modern multimodality therapy; isolated LRR was uncommon. The TN subtype in patients with IFLBC is associated with poor outcomes, and this indicates the need for new treatment approaches in this group.

A Comparison of Patient-Reported Outcomes After Nipple-Sparing Mastectomy and Conventional Mastectomy with Reconstruction.

INTRODUCTION: Nipple-sparing mastectomy (NSM) is increasingly used for breast cancer risk reduction and treatment. Prior small studies with variable control for baseline characteristics suggest superior satisfaction with NSM. The purpose of this study was to compare patient satisfaction following NSM and total mastectomy (TM) utilizing the BREAST-Q patient-reported outcome measure in a well-characterized patient population. METHODS: Patients at a single institution undergoing NSM or TM with immediate tissue expander/implant reconstruction who completed a follow-up BREAST-Q from 2007 to 2017 were identified by retrospective review of a prospective database. Baseline characteristics were compared, and linear mixed models were used to analyze associations with BREAST-Q scores over time. RESULTS: Of 1866 eligible patients, 219 (12%) underwent NSM, and 1647 (88%) underwent TM. Median time from baseline to BREAST-Q was 658 days. Patients with NSM were younger, more likely to be white, and had lower BMI. They more often had prophylactic surgery, bilateral mastectomies, lower-stage disease, and less often received chemotherapy/radiation than patients with TM. On multivariable analysis, after controlling for relevant clinical variables, there was no difference in satisfaction with breasts or satisfaction with outcome overall between NSM and TM patients. Psychosocial well-being and sexual well-being were significantly higher in the NSM group. After additionally controlling for preoperative BREAST-Q score in a subset of patients (72 NSM; 443 TM), only psychosocial well-being remained significantly higher in NSM patients. CONCLUSIONS: Patient-reported outcomes should be discussed with women weighing the risks and benefits of NSM to provide a better understanding of expected quality of life.

Influence of Age on the Clinical Outcome of Breast Cancer for Men and the Development of Second Primary Cancers.

BACKGROUND: Low incidence of breast cancer in men (BCM) (< 1% of all breast cancers) has led to a paucity of outcome data. This study evaluated the impact of age on BCM outcomes. METHODS: For this study, BCM patients treated between 2000 and 2011 were stratified by age (≤ 65 or > 65 years). Kaplan-Meier methods were used to compare overall survival (OS) and breast cancer-specific survival (BCSS). Competing-risk methods analyzed time to second primary cancers (SPCs), with any-cause death treated as a competing risk. RESULTS: The study identified 152 BCM patients with a median age of 64 years (range 19-96 years). The median body mass index (BMI) was 28 kg/m2. Men age 65 years or younger (n = 78, 51%) were more overweight/obese than men older than 65 years (n = 74, 49%) (89% vs 74%, respectively; P = 0.008). Both groups had similar nodal metastases rates (P = 0.4), estrogen receptor positivity (P = 1), and human epidermal growth factor receptor 2 (HER2)neu overexpression (P = 0.6). Men 65 years of age or younger were more likely to receive chemotherapy (P = 0.002). The median follow-up period was 5.8 years (range 0.1-14.4 years). The 5-year OS was 86% (95% confidence interval [CI] 80-93%), whereas the 5-year BCSS was 95% (95% CI 91-99%). The BCM patients 65 years of age and younger had better OS (P = 0.003) but not BCSS (P = 0.8). The 5-year cumulative incidence of SPC was 8.4% (95% CI 3.4-13.4%). The prior SPC rate was higher for men older than 65 years (n = 20, 31%) than for those age 65 years or younger (n = 7, 11%) (P = 0.008). This did not account for differences in life years at risk. No difference was observed in SPC cumulative incidence stratified by age (P = 0.3). CONCLUSIONS: Men 65 years of age or younger received more chemotherapy and had improved OS, but not BCSS, compared with men older than 65 years. For all BCM, SPC is a risk, and appropriate screening may be warranted.

Ultrasound-guided wire localization of focal ductal dilatation in the evaluation and treatment of pathologic nipple discharge.

Patients presenting with pathologic nipple discharge (PND) often pose a diagnostic and therapeutic challenge. We used ultrasound to identify focal ductal dilatation-hypothesized to be a radiographic manifestation of the causative lesion-in patients with PND and no relevant clinical or radiographic findings. Twenty-two excisions guided by ultrasound wire localization of focal duct dilation were performed. Surgical pathology revealed papilloma in 20 cases (91%); atypia or carcinoma was detected in 7 cases (32%). The ultrasound finding of focal duct dilatation enables excision of otherwise occult though clinically significant lesions and is worthy of further study.

Resource-stratified implementation of a community-based breast cancer management programme in Peru.

Breast cancer incidence and mortality rates continue to rise in Peru, with related deaths projected to increase from 1208 in 2012, to 2054 in 2030. Despite improvements in national cancer control plans, various barriers to positive breast cancer outcomes remain. Multiorganisational stakeholder collaboration is needed for the development of functional, sustainable early diagnosis, treatment and supportive care programmes with the potential to achieve measurable outcomes. In 2011, PATH, the Peruvian Ministry of Health, the National Cancer Institute in Lima, and the Regional Cancer Institute in Trujillo collaborated to establish the Community-based Program for Breast Health, the aim of which was to improve breast health-care delivery in Peru. A four-step, resource-stratified implementation strategy was used to establish an effective community-based triage programme and a practical early diagnosis scheme within existing multilevel health-care infrastructure. The phased implementation model was initially developed by the Breast Cancer Initiative 2·5: a group of health and non-governmental organisations who collaborate to improve breast cancer outcomes. To date, the Community-based Program for Breast Health has successfully implemented steps 1, 2, and 3 of the Breast Cancer Initiative 2·5 model in Peru, with reports of increased awareness of breast cancer among women, improved capacity for early diagnosis among health workers, and the creation of stronger and more functional linkages between the primary levels (ie, local or community) and higher levels (ie, district, region, and national) of health care. The Community-based Program for Breast Health is a successful example of stakeholder and collaborator involvement-both internal and external to Peru-in the design and implementation of resource-appropriate interventions to increase breast health-care capacity in a middle-income Latin American country.

Physician preference and patient satisfaction with radioactive seed versus wire localization.

BACKGROUND: Nonpalpable breast lesions require localization before excision. This is most commonly performed with a wire (WL) or a radioactive seed (SL), which is placed into the breast under radiographic guidance. Although there are advantages of each modality, there are no guidelines to address which patients should undergo WL versus SL. We investigated factors influencing the selection of SL versus WL at our institution and assessed patient satisfaction with each procedure. METHODS: Patients undergoing preoperative localization of nonpalpable breast lesions from May 2014 through August 2015 were included. Physicians were surveyed on surgical scheduling to evaluate factors influencing the decision to perform SL or WL. Patient satisfaction was evaluated with a survey at the first postoperative visit. Retrospective chart review was performed. RESULTS: 341 patients were included: 104 (30%) patients underwent SL and 237 (70%) underwent WL. There was no difference in patient age, benign versus malignant disease, or need for concomitant axillary surgery comparing the SL versus WL groups. Physician survey indicated that 18% of patients were candidates for WL only. Of the patients who were eligible for both, 88 (41%) ultimately underwent SL and 126 (59%) had WL. The most commonly cited reason for selection of one localization method or the other was physician preference, followed by patient preference or avoiding additional visit. There was no significant difference in self-reported preoperative anxiety level, convenience of the localization procedure, pain of the localization procedure, operative experience, postoperative pain level or medication requirement, or overall patient satisfaction comparing patients who underwent SL and WL. CONCLUSIONS: SL and WL offer patients similar comfort and satisfaction. Factors influencing selection of one modality over the other include both logistic and clinical considerations.

Close and Positive Lumpectomy Margins are Associated with Similar Rates of Residual Disease with Additional Surgery.

BACKGROUND: Current guidelines state that "no ink on tumor" constitutes adequate surgical margins for lumpectomy specimens. However, there remains uncertainty when tumor is close (<1 mm) to multiple inked margins. METHODS: All local excisions for invasive breast cancer during 3 years at one center were reviewed. Tumor characteristics, margin status, patient age, reoperations, and pathology of reexcised specimen were recorded. Chi-square analysis and regression models were used to identify factors associated with residual disease upon reoperation. RESULTS: In 533 lumpectomies for invasive cancer, 60 (11 %) had at least one positive margin, and 106 (20 %) had one or more close margin. Multiple margins were either close or positive in 67 cases. Reoperation was performed in 125 of 533 cases (23 %) for close or positive margins. Positive margins were significantly more likely to undergo reoperation compared with close margins (p < 0.001). On reoperation, 73 of 125 (58 %) demonstrated residual cancer, including 39 of 68 (57 %) with close margins, and 34 of 57 (60 %) with positive margins (p = 0.52). When multiple margins were close or positive, residual cancer was found on reexcision in 45 of 59 (76 %) cases as opposed to 34 of 79 (43 %) cases with only one involved margin (p < 0.001). When controlling for other factors, positive margins were no more associated with residual disease than close margins (p = 0.32), whereas multiple close or positive margins were associated with significantly higher risk of residual disease (odds ratio 6.1; p = 0.002; 95 % confidence interval 2.6-14.45). CONCLUSIONS: The only significant predictor of residual tumor was multiple close or positive margins. It may be appropriate to recommend reexcision for patients with multiple close margins.

Outcome of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy on patients with diaphragmatic involvement.

PURPOSE: The purpose of this study is to assess the short-term morbidity and mortality in patients undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) with diaphragmatic involvement. METHODS: All patients undergoing CRS/HIPEC at a tertiary care institution from April 2007 to October 2013 were retrospectively reviewed. Patients with diaphragmatic disease (Group 1) were compared to those who did not (Group 2). Univariate, propensity score analysis, and multivariate analysis were used to compare groups focusing on postoperative complications. RESULTS: A total of 199 patients underwent CRS/HIPEC. Diagnoses included appendiceal/colorectal cancers (56 %), pseudomyxoma peritoneii (12 %), and gastric cancer (7 %). Group 1 was composed of 89 patients (44.7 %) with diaphragmatic involvement, of which 37.1 % underwent diaphragm stripping and 62.9 % required a full-thickness diaphragmatic resection. Group 1 had longer operative times (p = 0.009), increased transfusion requirements (p = 0.007), less optimal cytoreduction (p = 0.010), longer ICU stay (p = 0.003), and overall hospital stay (p = 0.039). Major complications were significantly higher in Group 1: 26 (29 %) versus 16 (15 %), p = 0.020. Rate of respiratory complications was not different between groups (G1: 14/26, 53.8 % and G2: 6/16, 37.5 %, p = NS). Ninety-day mortality was not significantly different. Diaphragmatic involvement (Estimate 1.235, SE 0.387, p = 0.017) was an independent predictor of 30-day morbidity in patients with <5 organs involved in cytoreduction. CONCLUSIONS: Diaphragmatic involvement is associated with higher tumor burden and more complex operations. It is a strong independent predictor 30-day morbidity in patients with <5 organs involved in cytoreduction. However, perioperative mortality rates are not significantly different between the groups, suggesting that diaphragm stripping or resection is warranted in well-selected patients if it allows for complete cytoreduction.

Breast pathology review: does it make a difference?

BACKGROUND: Breast pathology is a challenging field, and previous work has shown discrepancies in diagnoses, even among experts. We set out to determine whether mandatory pathology review changes the diagnosis or surgical management of breast disease. METHODS: Cases were referred for pathology review after patients presented for surgical opinion to the Dubin Breast Center at Mount Sinai Medical Center over the course of 2 years. Surgical pathologists with expertise in breast disease reviewed slides submitted from the primary institution and rendered a second opinion diagnosis. Comparison of these reports was performed for evaluation of major changes in diagnosis and definitive surgical management. RESULTS: A total of 306 patients with 430 biopsy specimens were reviewed. Change in diagnosis was documented in 72 (17 %) of 430 cases and change in surgical management in 41 (10 %). A change in diagnosis was more likely to occur in patients originally diagnosed with benign rather than malignant disease (31 vs. 7 %, p < 0.001). Twelve (7 %) of 169 specimens initially diagnosed as benign were reclassified as malignant. A malignant diagnosis was changed to benign in 4 (2 %) of 261 cases. Change in diagnosis was less common in specimens originating from commercial laboratories than community hospitals or university hospitals (8, 19, 21 %, p = 0.023). Change in management was not dependent on initial institution. Type of biopsy specimen (surgical or core) did not influence diagnostic or management changes. CONCLUSIONS: We recommend considering breast pathology review based on the individual clinical scenario, regardless of initial pathologic diagnosis or originating institution.
