Statin Use

523 Background: Statins have been shown to target pathways related to breast cancer carcinogenesis, specifically in more aggressive breast cancer subtypes such as triple negative breast cancer (TNBC). Given the limited toxicity profile, low cost, and ease of use of statins, an association between statin therapy and improved breast cancer outcomes, particularly in aggressive breast cancers with more limited treatment options, could have important public health implications. Here we examine the association of statin therapy with breast cancer outcomes in women with stage I-III breast cancer, specifically TNBC. Methods: We utilized Surveillance, Epidemiology, and End Results (SEER)-Medicare and Texas Cancer Registry (TCR)-Medicare data. We included women age 66 years or older with histologically confirmed stage I-III breast cancer diagnosed from 2008-2015. We used multivariable Cox proportional hazards regression models to examine the association of statin use with overall survival (OS) and breast cancer specific survival (BCSS) adjusting for age, race, education, state buy-in, residence area, stage, subtype, endocrine therapy, radiation, chemotherapy, surgery, baseline statin use, comorbidity, and baseline hypertension. For BCSS, we accounted for the competing risk of death using the Fine and Grey method. We required all individuals to survive until 12 months post-diagnosis, which we defined as the start of the follow-up period, to account for immortal time bias. Results: We identified 45,063 patients with stage I-III breast cancer meeting inclusion criteria, out of which 22,518 (50.0%) received a statin within one year following diagnosis (statin-users). The 5-year cumulative estimates of breast cancer specific deaths were 5.9% and 6.9% for statin-users and non-users (P <.001), respectively. In the overall cohort, adjusted models showed a statistically significant association between statin use and improved BCSS (subdistribution hazard ratio [SHR], 0.82; 95% CI, 0.70 to 0.97; P =.021), but no association with OS (hazard ratio [HR], 0.96; 95% CI, 0.90 to 1.03; P =.23). The association was strongest in patients with TNBC for BCSS (SHR, 0.60; 95% CI, 0.42 to 0.86; P =.006) and OS (HR, 0.76; 95% CI, 0.61 to 0.95; P =.018). Stratification by stage showed that the effect of statin therapy in TNBC was limited to patients with localized disease. Our results were consistent using propensity score matched models and when limiting our analysis to statin therapy initiated following breast cancer diagnosis. Conclusions: Among women with non-metastatic breast cancer, we found that statin use was associated with an OS and BCSS benefit among women with TNBC. Our data suggest that statins may have a role as an adjuvant therapy in select patients with breast cancer and supports further investigation, particularly among patients with TNBC, for whom effective treatment options are more limited.

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.

e18210 Background: Although many studies have investigated the association of blood 25OH-vitamin D (vit-D) levels with breast cancer prognosis, the results have been mixed. It has been suggested that low vit-D concentrations were associated with advanced tumor stage and triple-negative (TNBC) subtype. We retrospectively investigated associations of serum vit-D levels with triple negative breast cancer outcome. Methods: Out of 797 cases of TNBC diagnosed at William Beaumont Hospital between 2006-2017, 163 patients had vit-D level available within 1 year prior to diagnosis. Analyses of vit-D levels was classified by 3 cut points (deficient, < 20.0 ng/mL; insufficient, 20.0-29.9 ng/mL; sufficient, ≥30.0 ng/mL). Primary outcomes are disease free survival (DFS) and overall survival (OS). SPSS statistics 25 software was used to analyze the data. Results: Median age of diagnosis of TNBC was 60. Of these patients 43.6% were diagnosed with stage I, 37.4% at stage II, 4.9% at stage III and 4.9% at stage IV. 47.2% of the patients had sufficient vit-D level prior to diagnosis, 28.2% with insufficient vit-D level and 24.5% with deficient vit-D. Vit-D deficiency was more prevalent in premenopausal than in postmenopausal women (33.3%, 41% and 25.6% in premenopausal women for deficient, insufficient and sufficient levels respectively vs 21.8%, 24.2% and 54% in postmenopausal women). Rates of Vit-D deficiency were not different between early disease and advanced disease (24.3% of patient with stage I-II vs 25% in patients with stage III-IV). Median OS and disease-free survival were not statistically different among the 3 different categories. 5-year OS was 91%, 91% and 85% for deficient, insufficient and sufficient levels respectively. 5-year DFS was 93%, 95% and 95% for deficient, insufficient and sufficient levels respectively. Multivariate COX regression analysis demonstrated that age and stage were associated with mortality, whereas vit-D level was not. Conclusions: The results from this study show that adequate vit-D level do not have an impact on OS and DFS in patients with triple negative breast cancer. Premenopausal women are more likely to have inadequate vit-D level. Identification and treatment of vitamin D deficiency is still important for musculoskeletal health and possibly extraskeletal health in general population and breast cancer survivors specifically.

179 Background: Triple negative breast cancer (TNBC) constitutes about 11-20% of all cases of breast cancer. TNBC has particularly aggressive clinical course and worse prognosis especially in African American (AA) women compared to white women. This retrospective study aims to investigate TNBC in the eastern North Carolina (NC) population, report treatment outcomes and determine the rate of recurrence. Methods: 202 TNBC patients treated at our institution between 1/01 and 11/09 were included in this analysis. Eastern NC has an AA population higher than the national average (30.2% vs. 12.4%) which is reflected in our patient demographics with 111 (55%) AA, 84 (41.6%) White, 5 (2.5%) Hispanic and 2 (1%) Chinese patients. Stage distribution was 41 (20%) stage I, 97 (48%) stage II, 37 (18%) stage III, 16 (8%) stage IV disease. Six patients (3%) had a diagnosis of DCIS and 5 (3%) were unknown. Majority was (79%) poorly differentiated carcinoma followed by moderately differentiated (13%) carcinoma. Variables were compared between groups using two-sample t-tests. Kaplan Meier curves were generated for overall survival (OS). Group was compared by log rank test. Results: The median FU time was 4.73 years (1.2–10.2). Median age at diagnosis was 53 (22-88) years overall, 51 years for AA and 57 years for White (p=0.01) patients. The overall median survival was 32.18 months with no difference between AA (32.39 months) and white (29.7 months) patients (p=0.785). 160 patients with stage I-III disease received chemotherapy with 96 patients (60%) receiving adjuvant and 64 (40%) receiving neoadjuvant therapy. The median survival for adjuvant patients was 37.08 months (6.87–113) vs 26.48 months (1.51–87.49) for neoadjuvant patients (p=0.001). 27 (14%) patients with stage I-III diseases experienced a local recurrence, 31 patients (15%) experienced distal recurrence with a median time to failure of 25.6 months. Conclusions: This study demonstrated no significant difference in median survival between AA and white patients; however, AA women were diagnosed at a younger age compared to white women. Patients treated with adjuvant chemotherapy had a significantly greater median survival when compared to patients receiving neoadjuvant treatment.
