6588 Background: Antiestrogen therapy has dramatically improved breast cancer survival rates but weight gain may be problematic. Studies evaluating antiestrogen therapy-related weight gain have yielded mixed results. Our primary objective was to evaluate weight changes in female breast cancer survivors (BCS) who received adjuvant anti-estrogen therapy for stage 0-III breast cancer. Methods: A retrospective chart review was conducted to evaluate weight changes in female chemo naive BCS receiving anti-estrogen therapy. Weights at initiation of hormonal therapy and at 6, 12, 24, and 36 months of follow-up were recorded. Median weight changes were calculated and were compared with Wilcoxon's signed rank test or the Kurskall-Wallis test. Results: A total of 622 women were included. The majority were white (77%), had stage I disease (78%), and were postmenopausal (82%). The median age at diagnosis was 59 years (range, 26–87). Median weight at initiation of hormonal therapy among premenopausal women was 65 kg (range 45.4–122.9). Median weight gain in this group was 0.4 kg (p = 0.009), 0.7 kg (p = 0.013), 1.9 kg (p = 0.0001), and 2.4 kg (p < 0.0001) at 6, 12, 24, and 36 months respectively. Among post-menopausal women, median weight at initiation of therapy was 71.7 kg (range 41.5–152.0) and median weight gain was 0.5 kg (p < 0.0001), 1 kg (p < 0.0001), 0.85 kg (p = 0.001), and 0.85 kg (p = 0.004) at 6, 12, 24, and 36 months respectively. Premenopausal patients had significantly more weight gain at 24 (p = 0.041) and 36 months (p = 0.005), as compared to postmenopausal patients. Among premenopausal women, 110/111 were treated with tamoxifen. Among post-menopausal women (n = 510), hormonal therapy was as follows: unknown n = 28 patients, tamoxifen n = 312, and AI n = 170. Overall, BCS treated with tamoxifen vs an AI had significantly more weight gain at 24 (p = 0.003) and 36 months (p = 0.009). Conclusions: Premenopausal patients are at higher risk for weight gain than postmenopausal patients. Further prospective research is warranted examining weight gain as a long-term side effect of anti-estrogen therapy in BCS. No significant financial relationships to disclose.

12076 Background: Weight gain is common after a breast cancer diagnosis. The incidence of and risk factors for weight gain during adjuvant endocrine therapy (ET) are poorly described. Limited data support an association between emergent symptoms and weight gain after a breast cancer diagnosis. Methods: We enrolled women with stage 0-III breast cancer initiating ET in a prospective clinic-based cohort. We assessed symptoms with the FACT-ES and PROMIS pain interference, depression, anxiety, fatigue, sleep disturbance and physical function measures at baseline (BL), 3, 6, 12, 24, 36, 48 and 60 months (mo). We defined emergent symptoms at 3 and/or 6 mo as worsening of 4 points from BL on PROMIS measures and 5 points from BL on the FACT-ES. We abstracted weight and menopausal status from charts. The primary outcome of this secondary analysis was weight gain (dichotomized as ≥5% vs < 5% of body weight compared to BL) through 60 mo. We evaluated the association between weight gain during ET and menopausal status. We also evaluated the associations between clinicodemographic factors and emergent symptoms with weight gain and if these associations differed by menopausal status. We performed logistic regression modeling with GEE to account for the longitudinal design. We identified a multivariable model for the set of factors associated with weight gain among pre-menopausal women taking ET. Results: 309 of 321 participants with BL and ≥1 follow-up (FU) weight were included. 263 (85%) had stage I-II disease, 99 (32%) were pre-menopausal, 259 (84%) were White and 32 (10%) were Black. Prior to ET, 45% had mastectomy, 66% had radiation, and 28% received chemotherapy. 4% of pre- and 82% of post-menopausal participants initiated an aromatase inhibitor (AI); all others initiated tamoxifen (Tam). 17% of pre-menopausal participants received ovarian suppression. At BL, 75% of Black and 59% of White participants were overweight/obese. With a median FU of 56 mo, 51% of pre- and 34% of post-menopausal participants gained ≥5% body weight (OR 1.09, 95% CI 1.07-1.13, p < 0.001). For each PRO measure, > 20% of participants had emergent symptoms. Worsening of physical function and pain interference scores at 3 and/or 6 mo were differentially associated with weight gain according to menopausal status (interaction p-values ≤0.05). On multivariate analysis, factors associated with weight gain among pre-menopausal participants were ET (AI vs Tam) (OR 2.8, 95% CI 0.90- 8.77, p = 0.08), prior mastectomy (OR 2.06, 95% CI 0.89-4.77, p = 0.09), emergent pain interference (OR 2.49, 95% CI 0.99-6.24, p = 0.05) and race (White vs other) (OR 7.13, 95% CI 1.29-39.4], p = 0.02). Conclusions: Weight gain during ET for breast cancer is more frequent among pre-menopausal than post-menopausal women. Worsening pain soon after ET initiation, receipt of AI, prior mastectomy and race may identify pre-menopausal women at risk for weight gain for whom prevention strategies are a priority.

e12057 Background: Obese and overweight women have an increased risk of BC and worse outcomes at the time of diagnosis compared to those at normal weight. Studies suggest that women tend to gain weight after BC cancer diagnosis and during CTx for early-stage disease, which may in turn increase risk for worse outcomes. We examined if weight gained during adjuvant CTx was associated with worse outcomes. Methods: We queried the prospectively maintained UT MD Anderson Cancer Center Breast Cancer (UTMDACC) Database for data on patients (pts) who received adjuvant third-generation CTx for early-stage BC cancer, including: demographics; tumor characteristics; and, body mass index (BMI) at diagnosis, pre- and post-CTx and one year after completion of treatment. Univariate and multivariate analysis (MA) by Cox regression were performed for survival outcomes across 3 categories according to BMI variation from start to end of CTx: >0.5-point loss or gain and stable BMI (± 0.5). Results: We included 1998 pts in this study. Women over 50 years old and post-menopausal were more likely to lose weight during adjuvant CTx, whereas women under 30 years old gained more weight (p<0.0001). At one year post-CTx, all pts tended to return to their original weight (ρ=0.3, p<0.0001). On MA, a BMI increase of 0.5 points was o associated with increased loco regional recurrence risk for both the entire cohort (HR 2.4; 95% CI, 1.122-5.166; p=0.0241) adjusting for grade and stage and for post-menopausal women (HR 3.774, 95% CI 1.241-11.447, p=0.0193) adjusting for Her2 status. Age <30 years old (HR, 2.52; 95% CI, 1.009-6.293; p=0.0478) and tumor stage 3 comparing to 1 (HR, 4.598; 95% CI, 2.754-7.677; p<0.0001) were associated with increased risk of death and tumor grade 2 (vs 3; HR, 0.547; 95% CI, 0.353-0.847; p=0.0069) was a protective factor on MA for the entire cohort. Conclusions: Weight gain during adjuvant CTx was associated with increased loco regional recurrence for the entire cohort and post-menopausal women, including pts who at year 1 returned to their normal weight. The effect of increased BMI during CTx on breast stroma, molecular profile and how it affects local recurrence is intriguing and needs to be further evaluated.

Abstract Strong epidemiological data exists implicating anthropometric risk factors in breast cancer aetiology. In premenopausal women the risk of breast cancer increases with increased height, yet decreases with increasing weight and BMI. Although the evidence is not strong, a counter-intuitive positive relationship between central adiposity and premenopausal breast cancer risk is emerging. In post-menopausal women an increased risk in breast cancer has been found for all anthropometric measures: height, weight, BMI, measures of central adiposity (waist:hip ratio and waist circumference) and weight gain, with breast size being a possible additional risk factor. Weight loss as a strategy for reducing breast cancer risk seems to offer a viable prophylaxis in obese post-menopausal women, although data are limited. The evidence for anthropometric measures in relation to breast cancer risk is consistently stronger for post-menopausal women compared with premenopausal women and seems to be dependent on age. A number of possible biological mechanisms have been offered to explain the link between breast cancer risk and anthropometric measures. It has been hypothesised that obesity, especially central fat deposits, linked to insulin resistance, increases circulating hormones such as oestrogens, androgens, insulin, insulin-like growth factor-1 (IGF-1), and decreased levels of hormone-binding proteins such as steroid hormone-binding globulin and IGF-1 binding protein-1. Thus there are resulting increased concentrations of bioavailable sex hormones, which have been linked to increased breast cancer risk. As obesity is an important modifiable risk factor, which has been linked to increased post-menopausal breast cancer, public health recommendations to maintain ideal weight throughout life are warranted.

Genitourinary Syndrome

Patients with breast cancer receiving antiestrogen therapy, specifically aromatase inhibitors, often suffer from vaginal dryness, itching, irritation, dyspareunia, and dysuria, collectively known as genitourinary syndrome of menopause (GSM). GSM can decrease quality of life and is undertreated by oncologists because of fear of cancer recurrence, specifically when considering treatment with vaginal estrogen therapy because of unknown levels of systemic absorption of estradiol. In this article, we review the available literature for treatment of GSM in patients with breast cancer and survivors, including nonhormonal, vaginal hormonal, and systemic hormonal therapy options. First-line treatment includes nonhormonal therapy with vaginal moisturizers, lubricants, and gels. Although initial studies showed significant improvement in symptoms, the US Food and Drug Administration recently issued a warning against CO2 laser therapy for treatment of GSM until additional studies are conducted. In severe or refractory GSM, after discussing risks and benefits of vaginal hormonal therapy, the low-dose 10-μg estradiol-releasing intravaginal tablet or lower-dose 4 μg estrogen vaginal insert and intravaginal dehydroepiandrosterone (prasterone) are options for treatment, because studies show minimal elevation in serum estradiol levels and significant improvement in symptoms. The decision to offer vaginal estrogen therapy must be individualized and made jointly with the patient and her oncologist.

Abstract Background Some endogenous hormones have been associated with breast cancer risk, but the nature of these relationships is not fully understood. Methods UK Biobank was used. Hormone concentrations were measured in serum collected in 2006–2010, and in a repeat subsample (N ~ 5000) in 2012–13. Incident cancers were identified through data linkage. Cox regression models were used, and hazard ratios (HRs) corrected for regression dilution bias. Results Among 30,565 pre-menopausal and 133,294 post-menopausal women, 527 and 2,997, respectively, were diagnosed with invasive breast cancer during a median follow-up of 7.1 years. Cancer risk was positively associated with testosterone in post-menopausal women (HR per 0.5 nmol/L increment: 1.18; 95% CI: 1.14, 1.23) but not in pre-menopausal women (pheterogeneity = 0.03), and with IGF-1 (insulin-like growth factor-1) (HR per 5 nmol/L increment: 1.18; 1.02, 1.35 (pre-menopausal) and 1.07; 1.01, 1.12 (post-menopausal); pheterogeneity = 0.2), and inversely associated with SHBG (sex hormone-binding globulin) (HR per 30 nmol/L increment: 0.96; 0.79, 1.15 (pre-menopausal) and 0.89; 0.84, 0.94 (post-menopausal); pheterogeneity = 0.4). Oestradiol, assessed only in pre-menopausal women, was not associated with risk, but there were study limitations for this hormone. Conclusions This study confirms associations of testosterone, IGF-1 and SHBG with breast cancer risk, with heterogeneity by menopausal status for testosterone.
