e18243 Background: Breast cancer (BC) patients with hormone-sensitive tumors often receive adjuvant hormone therapy for an extended period. How this affects lipid levels is not known. This study evaluated the relationship between dyslipidemia, a cardiovascular disease risk factor, and use of adjuvant hormone therapy among breast cancer patients. Methods: Randomized clinical trials for adjuvant hormone treatment in post-menopausal BC patients without residual cancer after primary treatment that reported lipid levels were identified in PubMed and EMBASE (N = 13). Bayesian network meta-analysis for longitudinal data was used to evaluate each drug’s effect on the mean changes in lipid levels from baseline. Key covariates were examined to determine heterogeneity of treatment effects; consistency of estimates was assessed using the arm-based method. Results: Toremifene improved all lipids more than any other hormone drug studied (see Table). Most aromatase inhibitors (AIs) did not significantly impact lipids. Age, baseline lipid value, and prior usage of Tamoxifen modified the drug effects on most lipids. However, these modifications do not change the overall conclusion. Conclusions: Selective estrogen receptor modulators (SERMs) are beneficial to most lipid profiles, but AIs do not have consistent impacts on lipids. Tailoring hormone drug prescriptions based on medical conditions of BC patients is recommended. [Table: see text]

540 Background: Risk of death from other malignancies (OM) and other causes (OC) than breast cancer (BC) increases with age. Effects of baseline factors on type of death were assessed with competing risks analyses. Methods: In NCIC CTG MA.17, 5,187 women free of recurrent breast cancer after 5 years of tamoxifen were randomized to letrozole (L, 2,593 women) or placebo (P, 2,594 women). The primary endpoint was disease free survival (DFS), and secondary, overall survival (OS). Follow-up was to October 9, 2005: median 3.9 years, range <0.1 to 7.0 years. Effects of competing risks were examined for endpoints of BC, OM, and OC for 11 baseline trial factors: treatment, age, menopausal status, duration of prior tamoxifen, adjuvant radiotherapy, bone fracture, osteoporosis, cardiovascular disease, hormone receptor status, nodal status, adjuvant chemotherapy. Lagakos’ hierarchical method (Lagakos, Appl. Statist. 1978; 27:235–241) was used to test for differential effects of baseline factors on type of death (BC, OM, OC). Results: Rate of censoring was 97.8%, with 256 deaths (BC, 102; OM, 50; OC, 100; unknown, 4). Non-breast cancer deaths accounted for 60% of known deaths; 72%, for those ≥70 years; and 48%, for those <70 years. Two baseline factors differentially affected type of death. Women with cardiovascular disease were more likely to die from OC (p=0.02), while those with osteoporosis were more likely to die of OM (p=0.03). Age and nodal status had directionally similar effects. Older women had shorter survival from all 3 causes of death (p=0.01). Lymph node positivity was associated with worse survival (p=0.003). Conclusions: Extended L provides similar proportional benefit in improving DFS for all ages of women (Muss ref abstract SABCS 2006). However, the magnitude of competing non-breast cancer, and non-treatment related, causes of death needs to be considered more frequently, since with early detection and improved therapies, breast cancer patients may increasingly be expected to survive their disease to die from another cause. The novel association between baseline osteoporosis and other malignancies is being explored quantitatively. No significant financial relationships to disclose.

549 Background: Aromatase inhibitors (AI) are a gold standard adjuvant endocrine therapy for postmenopausal women with breast cancer. A number of randomized trials (RCTs) have reported modest improvements in breast cancer outcomes from extending treatment with AI beyond the initial 5 years after diagnosis. However, less in known about the toxicity of extended AI compared with no therapy. Methods: We conducted a systematic review of MEDLINE to identify RCTs that compared extended AI to placebo or no treatment. The search was supplemented by a review of abstracts from the American Society of Clinical Oncology and San Antonio Breast Cancer Symposium meetings between 2013 and 2016. Odds ratios (ORs), 95% confidence intervals (CI), absolute risks, and the number needed to harm (NNH) associated with one adverse event were computed for prespecified safety and tolerability outcomes including cardiovascular disease, bone fractures, second cancers (excluding new breast cancer), treatment discontinuation due to adverse events and death without recurrence. Results: Seven trials comprising 16349 patients met the inclusion criteria. Longer treatment with AI was associated with increased odds of cardiovascular disease (OR = 1.18, 95% CI 1.00-1.40, P=0.05; NNH = 122) and bone fractures (OR = 1.34, 95% CI 1.16 - 1.55, P < 0.001; NNH = 72). Compared to control, longer AI therapy was associated with a higher odds of treatment discontinuation due to adverse events (OR = 1.45, 95% CI 1.25 - 1.68, P < 0.001; NNH = 20). Longer AI therapy did not influence the odds of second cancers (OR = 0.93, 95% CI 0.73-1.18, P = 0.56). There was a numerical excess of death without recurrence with longer AI therapy, but this was not statistically significant (OR = 1.11, 95% CI 0.9 - 1.36, P = 0.34). Conclusions: Longer durations of AI use are associated with increased cardiovascular events and bone fracture. There is a numerical, but non-statistically significant excess of deaths without breast cancer recurrence among patients receiving longer AI therapy. These data should be taken into account when considering extended adjuvant AI therapy for breast cancer patients.

11508 Background: Cardiovascular-disease risk factors (CVD-RFs) increase the risk of cardiac events in women undergoing chemotherapy. Less is known about the impact of CVD-RFs on healthcare utilization and costs. Methods: We examined breast cancer patients treated uniformly on SWOG clinical trials from 1999-2011. We identified baseline diabetes, hypertension, hypercholesterolemia, and coronary artery disease (CAD) by linking trial records to Medicare claims; obesity was identified using clinical records. The outcomes were emergency room visits (ER), hospitalizations and costs. Multivariable logistic and linear regression were used. Results: Among the 708 patients included in the analysis, 160 (22.6%) experienced 234 separate hospitalizations, and 193 (27.3%) experienced 311 separate ER visits. Diabetes, hypertension, hypercholesterolemia, and CAD were all associated with increased risk of hospitalizations and ER visit. Hypertension had the strongest association, with more than a threefold risk of hospitalization for those with hypertension compared to those without (OR [95% CI], 3.16 [1.85-5.40], p<0.001). For those with ≥3 CVD-RFs, the risk of hospitalization was greater compared to 0 or 1 CVD-RFs (OR [95% CI], 2.74 [1.71-4.38], p<0.001). Similar results were seen for ER visits. In the first 12 months after trial registration, patients with diabetes ($38,324 vs $30,923, 23.9% increase, p=0.05), hypercholesterolemia ($34,168 vs $30,661, 11.4% increase, p=0.02), and CAD ($37,781 vs $31,698, 19.2% increase, p=0.04) had statistically significantly higher total healthcare costs. Additionally, those with 2 significant CVD-RFs ($35,353 vs. $28,899, 22.3% increase, p=.005) had higher total healthcare costs. Conclusions: Our study demonstrates that the presence of both CVD-RFs and ER visits and hospitalizations are frequent among elderly BC patients. The risk of ER visits and hospitalizations is higher among patients with CVD-RFs, and increases with the number of RFs. Better management of CVD-RFs and more aggressive symptom management may be required to reduce both physical and financial toxicities to elderly patients undergoing BC therapy.
