Purpose The purpose was to assess whether patients with clinical multifocal or multicentric (MFMC) breast cancer determined by mammogram, ultrasound, or physical examination have inferior outcome compared with patients with clinical unicentric lesions. Patients and Methods We retrospectively analyzed 706 consecutive patients with stages I-III breast cancer treated at the M.D. Anderson Cancer Center (Houston, TX) from 1976 to 2003 who received neoadjuvant anthracycline-based chemotherapy followed by breast conservation therapy (BCT), mastectomy alone, or mastectomy plus postmastectomy radiation therapy. Results The mean follow-up was 66 months. At presentation, 97 of 706 patients had clinically MFMC disease (13.7%). The 5-year rate of locoregional failure was 10% for unicentric disease compared with 7% for MFMC disease (P = .78). Subset analyses of patients by treatment groups confirmed no statistical difference in locoregional control regardless of the type of locoregional treatment. Among patients with multifocal disease treated with BCT, there were no in-breast recurrences and one supraclavicular recurrence. Five-year disease-free survival and overall survival was equivalent between patients with MFMC and unicentric breast cancers. Conclusion Patients with clinical MFMC breast cancer at the time of diagnosis treated with neoadjuvant chemotherapy followed by locoregional therapy have similar 5-year rates of locoregional control, disease-free survival, and overall survival as those with unicentric disease. Clinically detected MFMC disease did not predict for inferior outcome.

Abstract Background Primary mucosal melanoma of the head and neck (MMHN) is a rare, aggressive tumor of neural-crest origin. Despite universal progress in cancer care, the prognosis of MMHN continues to remain dismal. Aims To analyze and report the outcomes of primary head and neck mucosal melanomas treated at Tata Memorial Hospital. Methods Retrospective chart review of all patients with a diagnosis of nonocular MMHN presenting to the institute between 1995 to 2003. Locoregional control and disease-free survival were used as outcome measures. Results 42 patients presenting within the study period with nonocular MMHN (oral-55%, sinonasal-40%, and pharyngeal-5%) at a median age of 53 years constituted the demographic cohort. 11 (26%) patients not amenable to any active anticancer treatment were treated with best supportive care alone and excluded from outcome analysis. 26 patients underwent surgery with complete resection of tumor. Seven (27%) also received adjuvant radiotherapy due to the adverse histopathologic features. Two patients were treated with radical radiotherapy due to unresectability, two patients received palliative chemotherapy, while one patient was treated with definitive chemoradiotherapy. With a mean follow-up of 11 months (range 1-58 months), the 3-year locoregional control and disease-free survival was 41% and 12% respectively. Age, sex, site of primary, tumor stage, surgical resection, margin status, depth of infiltration, and adjuvant radiotherapy did not affect outcome significantly. Conclusion Primary mucosal melanoma of the head and neck is a rare, but, aggressive tumor with a dismal prognosis. Surgical resection with clear margins offers the best chance of cure for early localized disease. The high incidence of locoregional as well as distant failures after surgical resection supports the use of adjuvant therapy. Deeper insights into the pathobiology of disease can help develop more specific and effective treatment strategies to improve long-term outcomes.

e12033 Background: Pakistan has the highest rate of breast cancer for any South Asian population and majority of the patients present with locally advanced or metastatic disease. We report on response and survival of primary locally advanced non-metastatic breast cancer in women treated with neoadjuvant Adriamycin/Taxanes (AT) based regimens at our institute. Methods: Between 1995 to 2009 the hospital information system identified 517 women with pathologically confirmed locally advanced breast cancer. All patients received neoadjuvant chemotherapy with AT based regimen followed by surgery. Median age was 43 years (range 17-71 years). AJCC stage; stage II 54% and stage III 46% of the patients. Axillary nodes were palpable in 72% of the patients at presentation. Histological sub-types; infiltrating ductal carcinoma 95%, infiltrating lobular carcinoma 3% and others 2% respectively. Pathological grade was I/II in 44% and grade III 56% of the patients. ER, PR, and Her2-neu receptors were positive in 44%, 40% and 24% of the patients respectively. Twenty one percent of the patients had triple negative breast cancer. Post operative radiotherapy was delivered to 94% of the patients. Patients with positive ER/PR receptors also received hormonal manipulation. Results: Following neo-adjuvant chemotherapy, pathological response was; complete response (CR) 13.5%, partial response 21%, stable disease 52% and progressive disease in 13% of the patients respectively. Breast conservation was possible in 36% of the patients. The 5 year disease free survival in patients with and without CR was 81% and 36% respectively. On multivariate analysis, T stage (p = 0.001) and response to neo-adjuvant chemotherapy (p = 0.001) were found to be independent predictors for disease free survival. Conclusions: Pathological response to neoadjuvant chemotherapy is a predictor of long term survival. Chemotherapy regimens with high response rates merit evaluation in randomized trials to improve outcome in locally advanced breast cancer.

Background. The impact of postmastectomy radiotherapy (PMRT) in patients receiving neoadjuvant chemotherapy (NAC) is unclear. The purpose of this study is to identify the patients who may benefit from PMRT. Methods. We retrospectively analysed patients with clinical stage II-III breast cancer who underwent NAC and modified radical mastectomy at our centre from 2007 to 2015. We investigated the relationship amongst locoregional recurrence rate (LRR), disease-free survival (DFS), and clinical pathological characters. Results. A total of 554 patients were analysed in this study. The median follow-up time was 65 months. Amongst the patients, 58 (10.5%) had locoregional recurrence, 138 (24.9%) had distant metastasis, and 72 (13.0%) patients died. The 5-year cumulative incidence of LRR and DFS was 9.2% and 74.2%, respectively. A total of 399 (72%) patients received PMRT and 155 (28%) did not. The 5-year LRR of the patients with PMRT (7.3% vs. 14.1%, P = 0.01 ) decreased significantly. We found that PMRT was an independent prognostic factor of LRR and DFS. Patients with the persistent involvement of 1–3 lymph nodes (ypN1) and more than 4 positive lymph nodes (ypN2-3) had a better outcome after PMRT than those without. However, the LRR and DFS of patients with negative lymph nodes at the time of surgery (ypN0) and who received PMRT showed no significant benefits. Amongst all patients with the three molecular subtypes of breast cancer, patients with triple-negative breast cancer had the highest pathological complete response rate but the worst prognosis ( P = 0.001 ). Conclusion. Results showed that PMRT significantly reduced the LRR of patients with clinical stage II-III breast cancer after receiving NAC and mastectomy. YpN0 patients derived no local control or survival benefit after receiving PMRT, whereas those with ypN1 and ypN2-3 could obviously benefit from PMRT.
