Background: Triple-negative breast cancer (TNBC) accounts for disproportionately poor outcomes in breast cancer, driven by a subset of rapid-relapse TNBC (rrTNBC) with marked chemoresistance, rapid metastatic spread, and poor survival. Our objective was to evaluate clinicopathologic and sociodemographic features associated with rrTNBC. Methods: We included patients diagnosed with stage I–III TNBC in 1996 through 2012 who received chemotherapy at 1 of 10 academic cancer centers. rrTNBC was defined as a distant metastatic recurrence event or death ≤24 months after diagnosis. Features associated with rrTNBC were included in a multivariable logistic model upon which backward elimination was performed with a P<.10 criterion, with a final multivariable model applied to training (70%) and independent validation (30%) cohorts. Results: Among all patients with breast cancer treated at these centers, 3,016 fit the inclusion criteria. Training cohort (n=2,112) bivariable analyses identified disease stage, insurance type, age, body mass index, race, and income as being associated with rrTNBC (P<.10). In the final multivariable model, rrTNBC was significantly associated with higher disease stage (adjusted odds ratio for stage III vs I, 16.0; 95% CI, 9.8–26.2; P<.0001), Medicaid/indigent insurance, lower income (by 2000 US Census tract), and younger age at diagnosis. Model performance was consistent between the training and validation cohorts. In sensitivity analyses, insurance type, low income, and young age were associated with rrTNBC among patients with stage I/II but not stage III disease. When comparing rrTNBC versus late relapse (>24 months), we found that insurance type and young age remained significant. Conclusions: Timing of relapse in TNBC is associated with stage of disease and distinct sociodemographic features, including insurance type, income, and age at diagnosis.

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.

Purpose Among Nigerian women, breast cancer is diagnosed at later stages, is more frequently triple-negative disease, and is far more frequently fatal than in Europe or the United States. We evaluated the contribution of an inherited predisposition to breast cancer in this population. Patients and Methods Cases were 1,136 women with invasive breast cancer (mean age at diagnosis, 47.5 ± 11.5 years) ascertained in Ibadan, Nigeria. Patients were selected regardless of age at diagnosis, family history, or prior genetic testing. Controls were 997 women without cancer (mean age at interview, 47.0 ± 12.4 years) from the same communities. BROCA panel sequencing was used to identify loss-of-function mutations in known and candidate breast cancer genes. Results Of 577 patients with information on tumor stage, 86.1% (497) were diagnosed at stage III (241) or IV (256). Of 290 patients with information on tumor hormone receptor status and human epidermal growth factor receptor 2, 45.9% (133) had triple-negative breast cancer. Among all cases, 14.7% (167 of 1,136) carried a loss-of-function mutation in a breast cancer gene: 7.0% in BRCA1, 4.1% in BRCA2, 1.0% in PALB2, 0.4% in TP53, and 2.1% in any of 10 other genes. Odds ratios were 23.4 (95% CI, 7.4 to 73.9) for BRCA1 and 10.3 (95% CI, 3.7 to 28.5) for BRCA2. Risks were also significantly associated with PALB2 (11 cases, zero controls; P = .002) and TP53 (five cases, zero controls; P = .036). Compared with other patients, BRCA1 mutation carriers were younger ( P < .001) and more likely to have triple-negative breast cancer ( P = .028). Conclusion Among Nigerian women, one in eight cases of invasive breast cancer is a result of inherited mutations in BRCA1, BRCA2, PALB2, or TP53, and breast cancer risks associated with these genes are extremely high. Given limited resources, prevention and early detection services should be especially focused on these highest-risk women.

e22228 Background: Breast cancer (BC) is the most common malignancy in women in Lebanon. Triple negative (TN) phenotype is known to be associated with an increased likelihood of recurrence and death. The purpose of this study is to determine the incidence, characteristics and survival of TN BC patients in a Medical Oncology department in a University Hospital in Lebanon. Methods: We retrospectively reviewed the pathology of all women with breast cancer that were seen in our institution between 1997 and 2008. TN BC patients (pts) were defined as those that were negative for all 3 receptors (estrogen, progesterone and HER2neu on immunohistochemistry). Pts' characteristics and survival of TN women were analyzed. Results: Of the 1599 breast cancer pts, 155 (9.7%) had a triple negative phenotype. Median age was 52 years. A positive family history of breast/ovarian cancer was found in 15 pts (10%). Pathology studies showed: invasive ductal carcinoma component in 138 pts (89%), pure medullary carcinoma in 7 pts (5%), pure invasive lobular carcinoma in 6 pts (4%), pure mucinous carcinoma in 3 pts (2%) and epidermoid carcinoma in 1 pt (1%). A grade III was found in 98 of specimens (63%). Twenty-six pts (17%) presented with stage I, 73 (47%) with stage II, 37 (24%) with stage III and 19 (12%) with stage IV. Twelve percent had inflammatory breast cancer. After a median follow up of 17 months (mths), 43 pts had relapsed (5 stage I, 18 stage II and 20 stage III). The most common sites of relapse were brain (in 20 % of cases), lungs (in 20% of cases) and bone (in 11% of cases). Five- year disease free survival and 5-year overall survival were respectively 75% and 88% for stage I, 58% and 72% for stage II and 40% and 63% for stage III. Adjuvant therapy was administered to 96% of pts among which a taxane-based regimen was used in 38% of cases . Median survival for stage IV was 19 mths with a first line taxane-based regimen used in 50% of cases. Conclusions: The incidence of TN BC in Lebanon is similar to that described in the literature. It has an aggressive course. Focus on understanding the biology of this particular BC subtype is essential for determining targets for future therapeutic options.

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.

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.
