11014 Background: Different studies have recently focused the attention on the so-called triple-negative pts, defined as ER-/PR- /HER2-. Although triple-negative tumours have been reported to be more aggressive, there are limited long-term data evaluating outcome as a function of this classification. Methods: NORA is an observational study aimed at investigating treatment modalities and clinical outcome of 3515 patients (pts) with early breast cancer (EBC) treated in 77 Oncological Centres in Italy from to 2000 to 2003, whose overall results have been already published. We now compare pathological characteristics and clinical outcome of pts for whom ER and PR andHER2 tests are negative with remaining pts (OTH). Results: 123 (4.1%) of 2968 evaluable pts resulted triple-negative. Out of these 123, 76 pts (61.7% vs 63.2% of OTH) were treated with conservative surgery (CS). Pathological T stage was T1 in55.3% pts (OTH: 59.6%), 47.9% were pN+ (OTH: 45.3%), 63.2 had G3 tumours (OTH: 34.1%). Chemotherapy alone was administered in 89.4% pts, mainly anthracycline-based (54.1%). At a median follow up of 27 months, all triple-negative pts were alive, 11 (8.9%) with relapse. No difference has been observed between two groups both in DFS (HR=0.74; 95%CI: 0.39–1.40; p=0.35) and OS (HR not estimated, p=0.99). Conclusions: Our results suggest that triple-negative pts have pathological characteristics similar to what observed in the other pts, receive CS in the same percentage of the cases, but have a 3-fold increase of undifferentiated tumours. On the contrary to what observed by other Authors, our data show that triple- negative pts do not have worse prognosis. Longer follow up is required to confirm these data. 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.

e13575 Background: Long-term safety of pregnancy after breast cancer still remained controversial, especially according to tumor subtypes. Prior results of other studies have limitations of short follow-up periods or small groups. Methods: We analyzed a population-based retrospective cohort data extracted from a random sample of 50% of women aged between 20 and 60 years who were diagnosed with breast cancer from 2002 to 2017 in the Korean National Health Insurance Service database. Propensity score matching analysis for age and Charlson Comorbidity Index (CCI) variables was performed for pregnant groups and non-pregnant groups with the same type of hormone therapy, chemotherapy and surgery. Study population was categorized to 4 biologic subgroups by the combination of hormone therapy, chemotherapy and target therapy. In this observational study, 1,566 patients with pregnancy after breast cancer were matched (1:2) to 2,462 non-pregnant patients of similar characteristics, adjusting for guaranteed bias. The matched patients were followed up to 7 years, or disease and mortality occurrence after the diagnosis of breast cancer. Survival estimates were calculated using the Kaplan-Meier analysis, groups were compared with the log-rank test. Results: Mean time from diagnosis to pregnancy was 3.4 years in study population. At a follow-up of 7 years after pregnancy, no inferiority in disease-free survival and overall survival was observed in pregnant patients factoring in treatment bias. In sub-analysis according to tumor subtypes, no difference in disease-free survival was observed between pregnant and non-pregnant patients in HR-positive and triple negative subgroup ( p= 0.088, p= 0.048, respectively). Likewise, no overall survival difference was observed in ER-positive patients and triple negative patients ( p= 0.05∼0.73, p= 0.03∼0.09, respectively). Conclusions: Our observational data provides reassuring evidence on long-term safety of pregnancy in young breast cancer patients, regardless of tumor subtypes.

Background: The incidence of pregnancy-associated breast cancer (PABC) is increasing, especially in the developed countries. Herein, we report the long-term outcomes of PABC from a single institution in an Arab country. Methods: Consecutive patients diagnosed to have PABC between 2005 and 2012 at a tertiary referral hospital from a Gulf cooperation council country were the subjects of the study. Long-term outcomes are reported, with a minimum follow-up of 8 years. Results: A total of 16 patients were evaluable for long-term survival analysis. The median age at the time of diagnosis was 31.5 (26-40) years. Nine (56%) patients were multiparous (> 5 previous pregnancies). The mean gestational age at diagnosis was 19.7±7.4 weeks. Immunohistochemistry revealed the following phenotypes: Luminal A 3 (18.8%); HER-2 enriched 8 (50%); triple-negative 5 (31.2%). Three patients underwent modified radical mastectomy as the initial treatment, of which 2 received adjuvant chemotherapy during pregnancy. For patients who received neoadjuvant or palliative chemotherapy, the response rate was 75% (pCR 2; CR 1; PR 6). After a median follow-up of 60 months, median progression-free survival was 36 months (95%CI 24.2 to 47.8), while the overall survival was 59 months (95%CI 31.6 – 86.4). Age, marker status, Ki-67 score, clinical stage and differentiation grade did not affect the PFS or OS on univariate analysis. Conclusions: Fifty percent of the patient with PABC expressed HER-2/neu protein, and 1/3rd had triple-negative disease. The rate of response to chemotherapy, and long-term survival may help to set a benchmark for studies from the region. Larger cohort studies may help to draw firm conclusions.

Objective: To compare the sociodemographic, diagnostic, clinical, and treatment-related characteristics and outcomes of patients with breast cancer in two hospitals in Mexico according to type of healthcare coverage. Methods: A retrospective cohort study of women with breast cancer according to public or private healthcare coverage in two hospitals was done. Patients were treated by the same group of physicians and healthcare infrastructure. Groups were compared using the chi-square test for categorical variables, Mann–Whitney U-test and Student’s t-test for quantitative variables, and Kaplan–Meier estimator and log-rank test for time dependent outcomes (including recurrence-free and overall survival). A value of p < 0.05 was considered statistically significant. Results: A total of 282 women were included. Mean age at diagnosis was 52 years. Women with public healthcare coverage were diagnosed more frequently with self-detected tumors (82.8% vs 47.9%, p < 0.001) and advanced clinical stage (III and IV) (31.1% vs 17.8%, p = 0.014). More women with public healthcare insurance underwent initial systemic treatment (41.1% vs 17.8%, p < 0.001) and mastectomy (70.1% vs 54.9%, p = 0.020), and received more chemotherapy (79.4% vs 43.8%, p < 0.001) and adjuvant radiotherapy (68.9% vs 53.4%, p = 0.017). Overall, no differences were found in survival outcomes according to healthcare coverage. Trends suggesting worse recurrence-free and overall survival were observed in patients with public coverage at 3 years follow-up in stage III (85.7% vs 67.3% and 100% vs 84.6%, respectively) and triple negative disease (83.3% vs 74.5% and 100% vs 74.1%, respectively). Conclusion: Strategies to promote preventive medicine, diagnostic mammograms, and prompt diagnosis of breast cancer in Mexican women with public health coverage are needed. Access to the main treatment modalities by Seguro Popular and good quality care by an experienced group of physicians likely explains the similar outcomes between patients with private and public healthcare coverage. However, trends suggesting worse survival for patients with public medical coverage with stage III and triple-negative disease should encourage close follow-up.

Worse Prognosis

28 Background: Triple-negative breast cancer (TNBC) is a subtype of breast cancer (BC) with unique clinical-pathological & prognostic characteristics. Studies have shown obesity to be risk factor for TNBC. Furthermore, patients (pts) with BC and overweight/obesity have a worse prognosis. Here we investigate body mass index (BMI) & weight trends among BC survivors. Methods: A retrospective review BC pts at Cancer Treatment Centers of America Atlanta from 2012-10/27/17. Definition of a survivor: pts who have completed definitive therapy with no evidence of disease. Survivor BMI & weight gain (kg) calculated from chart review. Weight gain in kg was recorded post chemotherapy, at 3, 6, 9, 12 month follow up. Inclusion: Pts with ER-PR-HER2- (TNBC), adults > 18 yo, pts who completed chemo (neoadjuvant or adjuvant) & surgery +/- radiation. Exclusion: Pts who died, had relapsed local disease or metastatic disease; missing BMI data; currently on chemotherapy; who did not receive chemotherapy; missing continuous BMI data or pathology report; lost to follow up. Results: 1756 BC pts with stage IA-IIIC identified, 300 pts identified as TNBC. A total of 134 patients met full inclusion/exclusion survivorship criteria. Average age of survivors = 52 (range 25-76). Stage: I = 38%; II = 50%, III = 12%. BMI categories: 0% underweight (BMI < 18.5 kg/m2), 15% normal weight (BMI 18.5 to < 25 kg/m2), 18% overweight (BMI 25 to < 30 kg/m2), 55% obese (BMI ≤30 kg/m2), 12% morbid obesity (BMI ≤ 40 kg/m2). Average BMI for all survivors = 32.23 +/-0.59 kg/m2 (range 19-52 kg/m2); post chemotherapy weight change = 0.53 +/-0.41 kg; at 3 month follow up = -0.16 +/-0.51 kg; at 6 month = -0.02 +/-0.54 kg; at 9 month follow up 1.20 +/-0.59 kg; at 12 month follow up = 2.25 +/-0.61 kg. BMI by stage: I = 32.81 +/- 1.00 kg/m2; II = 32.12 +/- 0.91 kg/m2; III = 32.44 +/- 1.27 kg/m2. Conclusions: In our study, female survivors with TNBC present with obesity and gain weight after chemotherapy. Also, weight gain continues at 9 & 12 months post definitive treatment. Survivors with TNBC should be treated with intensive weight loss interventions given that overweight/obesity is a risk factor for recurrence, worse prognosis, & cardiovascular events.
