Aim: To analyze therapy for metastatic triple-negative breast cancer (mTNBC), factors contributing to survival and costs. Patients & methods: Using 2010–2016 SEER-Medicare data, we identified women (≥65 years) with mTNBC. Results: Of 302 eligible patients, 152 (50%) received systemic therapy. In multivariable regression analyses, only age <75 years was associated with therapy receipt (odds ratio: 2.91; 95% CI: 1.79–4.74); and only systemic therapy significantly reduced risk of death (hazard ratio: 0.34; 95% CI: 0.26–0.44). Median overall survival was 13.4 (95% CI: 11.3–15.1) vs 3.3 months (95% CI: 2.7–3.9) in therapy vs no-therapy cohorts. Mean per-patient-per-month costs <30 days before end-of-life/follow-up were $14,100 and $15,600 (2019 USD), respectively. Conclusion: Poor outcomes and high costs indicate need for more effective mTNBC therapy.

e22214 Background: Triple negative breast cancer (BC) is a distinct group of tumors that show common but heterogeneous morphologic, genetic, and immunophenotypic features. Despite differences in the definition and prevalence, it comprises 8% to 20% of all breast cancers and is associated with an aggressive clinical course with significant risk of either local or systemic relapse and subsequent increased risk of death on short term follow up (particularly in the first 5 years).We study the pathological characteristics and the clinical outcome of a cohort of 77 triple negative BC patients (pts) diagnosed at our Institution. Methods: Between January 1999 and September 2008, 77 (stage I to III) triple negative BC pts. were retrospectively analyzed. All pts had their receptor status, Her neu, ck-5, ck-6 and staining for EGFR by the same pathologist. Pathological parameters (Pp) analyzed were: status of axilary lymph nodes (LN), nuclear grade, histologic grade, mitotic index and vascular invasion and the use of antraciclins in the adjuvant setting. Univariate and multivariate analysis (proporcional hazard regression Cox model) for the Pp associated with relapse, and the log rank test to compare two curves of each Pp for disease free survival (DFS), and overall survival (OS) were performed. Results: The median age was 57.8 years (range 30–86 years).The median follow up time was 57.7 months (range, 4- 241). From 77 Pts. analized, 65 (84.4%) were basal-like and 43 (64.6%) of those were GH3. Stage at the time of presentation was: 16 (20,7%) stage I; 40 (51,9%) stage II; 21 (27,7%) stage III. Pre-menopausal status was 29,48% (23 pts.), and 61% (47 pts) were LN negative. Overall, relapse rate was 38.5 % (n= 30), 63 Pts (81.8%) are still alive. Median DFS was not reached. Global DFS and OS were 59% and 79% respectively, and status of LN was the only prognostic factor. LN- vs LN+ DFS (p< 00.02) and OS p (< 0.02).All others Pp analyzed were not statistically significative. Conclusions: Despite previous studies have demonstrated that triple negative is an independent marker of poor prognosis in BC as a whole, in the LN-negative, and LN-positive groups, in this basal like population only positive LN was an independent poor prognostic factor for DFS and OS. No significant financial relationships to disclose.

e14014 Background: Triple-negative breast cancer (TNBC) is an aggressive subtype with high propensity of brain metastases (BM). Outcomes after upfront stereotactic radiosurgery (SRS) for BM from TNBC patients are not well defined. We evaluated outcomes and identified prognostic factors for such patients. Methods: We reviewed 57 consecutive patients treated with upfront SRS for BM from TNBC in May 2008–April 2018 at a large-volume cancer center. Endpoints were overall survival (OS) from BM diagnosis and freedom from BM progression (FFBMP) after initial SRS. BM progression was defined as local and/or distant brain failure (LBF or DBF) after initial SRS; LBF was radiographic progression of treated lesions, assessed by a neuroradiologist or treating physician excluding post-radiation changes or radiation necrosis. Kaplan-Meier and Cox proportional hazard regression analyses were used to estimate survival outcomes and identify prognostic factors. Results: In this cohort of 57 patients with a median age of 53 y (range 26–82) at BM diagnosis and follow-up time of 12.2 months (mo, range 0.8–97.5), median time to BM development from TNBC diagnosis was 23.7 mo (range 0.7‒271.1). Estimated median OS time from initial BM diagnosis was 13.1 mo (95% CI 8.0‒19.5). In univariate analysis, Karnofsky performance score (KPS) > 70 (p = 0.03), having < 3 BMs (p = 0.016) at BM diagnosis, and BM as first site of metastasis (p = 0.041) were associated with longer OS. On multivariate analysis, KPS ≤70 was associated with higher risk of death (HR 3.0, p = 0.03). Of 46 patients with imaging follow-up for FFBMP assessment, 29 (63%) developed BM progression after initial SRS with an estimated median FFBMP of 7.4 mo (95% CI 5.7–12.7). Median times to LBF and DBF were 10 mo (range 0.3–97) and 5.9 mo (range 0.3–90.8). Estimated cumulative LBF rate was 17.8% (95% CI 2%–31.1%) and DBF 61.1% (95% CI 40.8%–74.4%) at 12 mo. Number of BMs at BM diagnosis (≥3 vs < 3) was not associated with FFBMP (p = 0.7). Of the 29 patients with BM progression, 5 did not receive salvage radiation therapy (RT) and 24 received salvage RT (SRS, whole-brain radiation [WBRT], or both SRS+WBRT). Receipt of salvage RT was associated with longer survival (median 21.7 mo vs. 7.0 mo for no salvage RT, p < 0.0001) and did not differ by type of salvage RT (median OS 18.6 mo for WBRT; 26.2 mo for SRS+WBRT; 35.9 mo for SRS, p = 0.08). Conclusions: We reported a median OS of 13.1 mo and FFBMP of 7.4 mo in TNBC patients with good local control. Good KPS was independent prognostic factor for better OS. FFBMP did not differ by number of SRS-treated brain lesions ( < 3 vs ≥3). Further prospective studies of larger numbers of patients needed for more accurate comparisons of treatment types.

Abstract Background TNBC comprises a distinct disease entity with a unique microenvironment of TILs, the immunogenic potential of TNBC is derived from its genetic instability and high mutation rate. Tumors from patients with TNBC are more likely than tumors from patients with other subtypes to exhibit chromosomal instability and potential mutations. Objectives The study aims to evaluate the prevalence of CD8+ TILs biomarker by IHC in triple negative breast cancer and its prognostic value. TILs are an important prognostic value for the response of patient to chemotherapy the greater number of TILS is associated with higher probability of response to chemotherapy also decrease recurrence. TILS in triple negative breast cancer suggest a likely option for immunotherapy in this disease. Patients and Methods This is a retrospective study, which was carried on 30 female patients, Clinical data and paraffin wax block of female patients with triple negative breast cancer are to be collected from the breast cancer unit, department of clinical Oncology and Nuclear medicine Ain Shams university and Matarya teaching hospital. Results Several large systematic reviews and meta-analyses have confirmed that high levels of TILs are associated with better disease free survival and overall survival only in triple negative and HER2 positive subtypes, with no significant benefit seen in estrogen receptor positive breast carcinoma. In the Breast International Group (BIG) 02-98 trial shows that for every 10% increase in the intertumoral TILs there was a 17% reduced risk of relapse, and 27% reduced risk of death regardless of chemotherapy type. Also in eastern cooperative oncology group trial (ECOG) 2197, and 1199 showed that for every 10% increase in TILs, a 14% reduction of risk of recurrence, and 19% reduction in risk of death were observed. Conclusion Our study showed that All our patients (100%) were positive for CD8+, with a minimum range of 1% and a maximum range of 60%, most of the patients (20 patients) had CD8% between (10% to 20%). High levels of CD8 + TILs are good prognostic indicators in TNBC. our study showed that there were associations of CD8+ TILs infiltrate status with longer progression free survival and better overall survival in triple-negative breast cancer, but were not statistically significant probably due to our small sample size.

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.

Triple-negative breast cancer (TNBC) is characterized by the absence of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). It accounts for 15%–20% of all breast cancers and is associated with an aggressive evolution and poor outcomes with the majority of recurrences and deaths occurring in the first 5 years. Chemotherapy remains the mainstay of treatment in the absence of effective targets, but the good understanding of immune tumor microenvironment, the identification of immune-related targets, and the role of tumor-infiltrating lymphocytes (TILs) in TNBC has allowed to develop promising immunotherapeutic strategies for this unique subset of breast cancer. Recently, immunotherapy is being extensively explored in TNBC and clinical trials have shown promising results. In this article, we tried to explain the rationale and mechanisms of targeting the immune system in TNBC, to report the results from recent clinical trials that put immunotherapy as a new standard of care in TNBC in addition to ongoing trials and future directions in the next decade.
