162 Background: Prospective randomized clinical trials have demonstrated a significant advantage from postoperative adjuvant chemotherapy for patients with breast cancer. However, triple-negative breast cancer is high rate of early recurrence. Therefore, patients who do not achieve pathological complete response (pCR) for neoadjuvant chemotherapy have worse long-term survival than patients who achieve pCR. Treatment after adjuvant chemotherapy and neoadjuvant chemotherapy is not established yet. We notice that TS-1 improve early recurrent rate of breast cancer. TS-1 proved good response for advanced breast cancer and long-term therapy is possible. We planned the study for the purpose of inspecting it about the safety, completion and efficacy of giving TS-1 after standard therapy of triple negative breast cancer for one year. Methods: The patients with stage ±/II/ III triple negative breast cancer received neoadjuvant or adjuvant chemotherapy and surgery and/or radiotherapy. Furthermore, the cases of neoadjuvant chemotherapy did not achieved pCR. After that, dose of TS-1 is 80mg/m² administered orally daily for 2 weeks followed by a 1-week rest period given as 3-week cycles. Results: 63 patients were enrolled, including 44 patients received neoadjuvant chemotherapy and 19 patients received adjuvant chemotherapy. The average age is 50 years (28-68 years). 38 cases (60.3%) brought oral administration for one year to completion. The reasons of discontinuance were 15 cases of toxicity and 10 cases of recurrence. Average relative dose intensity was 80%. The compliance of TS-1 was 70.1% (222.4 days). Overall survival of 3 years was 86.47%, progression-free survival 50.8%. The overall incidence of toxicity was 54 cases (85.7%), and grade 3 toxicity occurred in 21 cases (33.3%). Conclusions: The compliance of TS-1 was approximately equal to the compliance for gastric cancer in spite of receiving treatments of anthracycline and/or taxane. The toxicity was approximately equal to the results for metastatic breast cancer. TS-1 administered orally for one year was feasible for triple negative breast cancer received standard therapy.

10519 Objective. Triple-negative breast cancer is defined as a subtype of invasive breast cancer which lacks estrogen and progesterone receptor expression as well as HER2/neu expression and is highly similar to the basal-like subtype defined by gene expression profiling. Method. 1,143 patients treated at MD Anderson Cancer Center in neoadjuvant trials were included in a retrospective comparative analysis between triple-negative tumors and non-triple-negative tumors for response to neoadjuvant chemotherapy as well as long- term survival. Results. 827/1,143 (72%) patients had received taxanes, either as a single-agent (n=60) or in combination with anthracycline (n=767), whereas the remainder patients received an anthracycline-only chemotherapy. Overall 258/1,143 (23%) tumors were triple- negative. Complete pathological response (pCR) was achieved in 63/257 (25%) patients with triple-negative tumors compared to 99/888 (11%) in patients with non-triple-negative tumors (odds ratio [OR] 1.14, 95%CI: 1.09–1.20, p=.0082). Triple-negative status correlated significantly with high nuclear grade (p<.0001), whereas no significant correlation with any established clinicopathologic parameter was observed. However, 5-year overall survival (5yrOS) was 66% in the triple-negative group compared to 83% in the non-triple-negative control group (OR 2.1, 95%CI: 1.6–2.8, p<.0001). In multivariate analyses, triple-negative status (hazard ratio [HR] 2.0, 95%CI: 1.4–2.8, p<.0001), high nuclear grade, increased tumor size (HR 1.5, 95%CI: 1.3–1.8, p<.0001), positive nodal status (HR 1.4, 95%CI: 1.2–1.7, p=.0002) and high nuclear grade (HR 1.7, 95%CI: 1.1- 2.4, p=.0089) were significantly associated with decreased 5yrOS. When survival was analyzed according to both response rate and triple negative status, achievement of pCR was a stronger predictor of survival compared to triple-negative status. Conclusion. Triple- negative expression status among patients with breast cancer constitutes an independent unfavorable prognostic factor with regards to overall survival unless achieving pCR after neoadjuvant chemotherapy. No significant financial relationships to disclose.

PURPOSE There are sparse data on the outcome of patients with locally advanced breast cancer (LABC). This report is on the prognostic factors and long-term outcome from Cancer Institute, Chennai. METHODS This is an analysis of untreated patients with LABC (stages IIIA-C) who were treated from January 2006 to December 2013. RESULTS Of the 4,577 patients with breast cancer who were treated, 2,137 patients (47%) with LABC were included for analysis. The median follow-up was 75 months (range, 1-170 months), and 2.3% (n = 49) were lost to follow-up at 5 years. The initial treatment was neoadjuvant concurrent chemoradiation (NACR) (77%), neoadjuvant chemotherapy (15%), or others (8%). Patients with triple-negative breast cancer had a pathologic complete response (PCR) of 41%. The 10-year overall survival was for stage IIIA (65.1%), stage IIIB (41.2%), and stage IIIC (26.7%). Recurrence of cancer was observed in 27% of patients (local 13% and distant 87%). Multivariate analysis showed that patients with a tumor size > 10 cm (hazard ratio [HR], 2.19; 95% CI, 1.62 to 2.98; P = .001), hormone receptor negativity (HR, 1.45; 95% CI, 1.22 to 1.72; P = .001), treatment modality (neoadjuvant chemotherapy, HR, 0.56; 95% CI, 0.43 to 0.73; P = .001), lack of PCR (HR, 2.36; 95% CI, 1.85 to 3.02; P = .001), and the presence of lymphovascular invasion (HR, 1.97; 95% CI, 1.60 to 2.44; P = .001) had decreased overall survival. CONCLUSION NACR was feasible in inoperable LABC and gave satisfactory long-term survival. PCR was significantly higher in patients with triple-negative breast cancer. The tumor size > 10 cm was significantly associated with inferior survival. However, this report acknowledges the limitations inherent in experience of management of LABC from a single center.

Purpose Triple-negative breast cancer (TNBC) is defined by the lack of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2) expression. In this study, we compared response to neoadjuvant chemotherapy and survival between patients with TNBC and non-TNBC. Patients and Methods Analysis of a prospectively collected clinical database was performed. We included 1,118 patients who received neoadjuvant chemotherapy at M.D. Anderson Cancer Center for stage I-III breast cancer from 1985 to 2004 and for whom complete receptor information were available. Clinical and pathologic parameters, pathologic complete response rates (pCR), survival measurements, and organ-specific relapse rates were compared between patients with TNBC and non-TNBC. Results Two hundred fifty-five patients (23%) had TNBC. Patients with TNBC compared with non-TNBC had significantly higher pCR rates (22% v 11%; P = .034), but decreased 3-year progression-free survival rates (P < .0001) and 3-year overall survival (OS) rates (P < .0001). TNBC was associated with increased risk for visceral metastases (P = .0005), lower risk for bone recurrence (P = .027), and shorter postrecurrence survival (P < .0001). Recurrence and death rates were higher for TNBC only in the first 3 years. If pCR was achieved, patients with TNBC and non-TNBC had similar survival (P = .24). In contrast, patients with residual disease (RD) had worse OS if they had TNBC compared with non-TNBC (P < .0001). Conclusion Patients with TNBC have increased pCR rates compared with non-TNBC, and those with pCR have excellent survival. However, patients with RD after neoadjuvant chemotherapy have significantly worse survival if they have TNBC compared with non-TNBC, particularly in the first 3 years.

Abstract Background Triple negative breast cancer (TNBC) (estrogen receptor (ER) – negative, progesterone receptor (PR) - negative, and human epidermal growth factor receptor 2 (HER2) -negative) is an aggressive subtype of breast cancer that is more common in younger women, carries a poorer prognosis and has a greater metastatic potential than receptor positive subtypes. Radiation therapy’s ability to improve outcomes, especially the overall survival is controversial, more so among African American patients. The objective of this study is to evaluate local control and survival rates of TNBC patients treated with radiotherapy (RT) in our institution with a sizeable cohort of African American women. Methods This is a retrospective analysis of 67 TNBCs (2007–2017) at an academic state institution who underwent a lumpectomy and /or mastectomy (surgery) followed by adjuvant irradiation to a median total dose of 50 Gy (range 40.5–50.40 Gy). Chemotherapy was administered in a neoadjuvant (32) or adjuvant setting (35). For all 67 TNBCs, local control (LC), overall survival (OS), and disease-free survival (DFS) were estimated using the Kaplan-Meier method. The significance of survival variables was analyzed using the Cox univariate and multivariate proportional hazards model. A p-value of less than 0.05 was considered statistically significant. The SPSS 24.0 software was used for data analysis. Results The baseline characteristics of all 67 TNBCs were measured with median follow up of 58 months (range 10–142 months). Patients were stratified into two groups (neoadjuvant chemotherapy-RT (32) vs. adjuvant chemotherapy-RT (35)). The five-year rates for LC, DFS and OS were 14.8 % vs. 47.9 % (p = 0.002), 24.2% vs. 53.1 % (p = 0.015), and 65.1% vs. 92.2% (0.002) respectively. On Cox multivariate analysis, patients who received adjuvant chemotherapy were associated with statistically improved significant LC (p = 0.002) and OS (p = 0.002). The variables included were: BMI (p = 0.050), distance travelled (p = 0.027), 8th AJCC TNM staging (p = 0.018) and tumor grade (p = 0.022). Conclusion In this hypothesis-generating report, among TNBC patients undergoing RT, adjuvant chemotherapy appears to be better than neoadjuvant chemotherapy in determining the clinical outcomes.
