Abstract PurposeThe body mass index (BMI) is commonly used as a simple indicator of obesity; patients with early-stage breast cancer who are obese (OB) per BMI measurements have been shown to have high postoperative recurrence and low survival rates. On the other hand, it has been shown that lymphocytes present in the vicinity of malignant growths that are involved in the tumors’ immune responses influence the efficacy chemotherapy. Therefore, we hypothesized that OB patients with breast cancer have a lower density of tumor-infiltrating lymphocytes (TILs), which may influence the therapeutic effect of preoperative chemotherapy (POC). In this study, we measured pretreatment BMI and TILs in patients with breast cancer who underwent POC, examined the correlations between these two factors, and retrospectively analyzed their therapeutic outcomes and prognoses.MethodsThe participants in this study were 421 patients with breast cancer who underwent surgical treatment after POC between February 2007 and January 2019. The patient’s height and weight were measured before POC to calculate the BMI (weight [kg] divided by the square of the height [m2]). According to the World Health Organization categorization, patients who weighed under 18.5 kg/m2 were classified as underweight (UW), those ≥18.5 kg/m2 and >25 kg/m2 were considered normal weight (NW), those ≥25 kg/m2 and <30 kg/m2 were overweight (OW), and those ≥30 kg/m2 were OB. The TILs were those lymphocytes that infiltrated the tumor stroma according to the definition of the International TILs Working Group 2014.ResultsThe median BMI was 21.9 kg/m2 (range, 14.3–38.5 kg/m2); most patients (244; 64.5%) were NW. Among all 378 patients with breast cancer, the TIL density was significantly lower in OB than in NW and OW patients (vs. NW: p=0.001; vs. OW: p=0.003). Furthermore, when examining patients with each breast cancer type individually, the OS of those with TNBC who had low BMIs was significantly poorer than that of their high-BMI counterparts (log rank p=0.031).ConclusionsOur data did not support the hypothesis that obesity affects the tumor immune microenvironment; however, we showed that being UW does affect the tumor immune microenvironment.

94 Background: Weight gain concerns breast cancer patients, can impact quality of life, may lead to therapy non-adherence, and is associated with increased recurrence risk and mortality. Early placebo-controlled trials did not identify a clear correlation between Tamoxifen (TAM) and weight gain; gain due to aromatase inhibitors (AIs) is not well characterized. We hypothesized that weight gain occurs more frequently than previously reported in breast cancer patients receiving endocrine therapy. Methods: This is a retrospective chart review investigating body mass index (BMI) change in women after breast cancer therapy. Patients with early stage breast cancer and whom had BMI and treatment data (at least 90 days) from 2003-2012 were identified in The Columbus Breast Cancer Tissue Bank. Patients were separated by treatment received: chemotherapy with and without endocrine therapy vs. endocrine therapy alone (including both TAM and AIs) vs. no other treatment. Results: A total of 970 subjects were included in the analysis. At diagnosis and/or treatment initiation, patients’ mean BMI was 29.2 ± 7.0 kg/m2; mean age 53.7± 11.6 years; and average length of therapy/follow up per patient, 1833 days (range 90-3,990). Patients who received an AI alone had significantly decreased BMIs during therapy (-0.65± 0.29 kg/m2, p = 0.025), whereas patients receiving chemotherapy alone, chemotherapy with TAM, or TAM followed by AI therapy, had significantly increased BMIs (0.51 ± 0.25, 0.73 ± 0.26, 1.01 ± 0.51 kg/m2; p = 0.039, 0.005, 0.045, respectively). Both older age and a higher BMI at diagnosis were associated with a significantly greater decline in BMI over treatment time (p < 0.001 and p < 0.001, respectively). In a multivariate regression model, after adjusting for age and initial BMI effect, the BMI change noted among different treatment groups was no longer significantly different (p = 0.43). BMI change was not statistically associated with treatment length (p = 0.26). Conclusions: Our review of a large, early stage breast cancer patient cohort showed no association between weight gain and endocrine therapy after adjusting for the effect of initial BMI and age at diagnosis. Additional study is needed to identify other factors impacting weight in this population.

Adverse Prognostic Factor

1044 Background: Obesity represents a well-known risk factor for the development of breast cancer and an adverse prognostic factor in early disease. Overweight is associated with reduced efficacy of aromatase inhibitors in adjuvant setting. Few data have been reported about the potential relationship of overweight and outcome in advanced breast cancer (ABC). Methods: We retrospectively evaluated body mass index (BMI) in a consecutive series of 400 ABC patients treated at our institution. BMI was calculated at baseline of diagnosis of ABC. We evaluated association of BMI and other prognostic and predictive markers with Progression Free Survival (PFS) and Overall Survival (OS). We evaluated PFS at first and subsequent lines of chemotherapy (CT) and endocrine therapy (ET). Overweight patients were defined as having BMI > 25. Results: Overweight patients were 52%. Median age of the population was 58 years. Median OS was 33.7 months. Overall, 76% of patients presented with ER+ and 17.7% with HER2+ ABC.Overweight was associated with increased age at diagnosis, menopausal status and luminal B or triple negative immunophenotype. At multivariate analysis, BMI > 25 was associated with better PFS at first-line ET (HR= 0.68, 95% CI 0.46-0.99). BMI was not associated with OS. Conclusions: BMI at baseline does not seem to be an adverse prognostic factor for ABC patients. Overweight may be associated with better PFS in endocrine responsive ABC treated with ET, especially in first-line setting. The role of BMI in ABC deserves to be further investigated.
