e12508 Background: Recurrence rates for early breast cancer vary in different studies from 7% to 18%. Recurrent breast cancer is associated with poorer outcome and higher mortality rates. The recurrence rate in the Kenyan population remains unknown despite high prevalence of known risk factors. Methods: Single institution retrospective study of all women (18 -75 years) treated for early breast cancer at a single center private tertiary unit from 2009 to 2017. Results: 239 patient records were reviewed. The mean age at diagnosis was 51 (SD13.1). 98% of women presented with a palpable breast lesion. The molecular sub-type’s prevalence was: ER/PR+ (76%), triple negative (12.1%), HER2+ (2.9%). The overall recurrence rate was 7.2%, 66% recurrences were loco-regional, while 27% were metastatic disease, with 61% of the recurrences being detected initially on clinical/ self-breast examination. 77% of the recurrences were in women with ER/PR+ molecular sub-types. Recurrences in women with DCIS (2/27) were invasive breast cancers. There were no identified risk factors on uni-variate and multivariate regression analysis which conferred a risk of breast cancer recurrence. Discussion: The mean age at diagnosis in this group is younger than the western average (65 - 75 years). Majority of the women presented with symptoms – a presentation that differs from that of countries with a national breast cancer screening program. The molecular distribution of breast cancers is comparable to western populations. Conclusions: Recurrence rate for early breast cancer in this series is 7.2%, which is comparable with documented western data, with majority of the recurrences being detected initially on clinical/self-breast examination.

PURPOSE: In this multicenter trial, toremifene 40 mg/d was compared with tamoxifen 20 mg/d, both given orally for 3 years to postmenopausal, axillary node–positive women after breast surgery. PATIENTS AND METHODS: The first 899 patients (toremifene, n = 459; tamoxifen, n = 440) of the total of 1,480 patients accrued to the trial were included in this scheduled safety analysis. The mean follow-up time was 3.4 years. RESULTS: The two treatment groups were well balanced with respect to patient and disease characteristics. The subjective side-effect profile was similar in both treatment groups. Slightly more vascular complications (deep vein thromboses, cerebrovascular events, and pulmonary embolisms) were seen among tamoxifen-treated patients (5.9%) as compared with toremifene-treated patients (3.5%) (P = .11), whereas bone fractures (P = .09) and vaginal leukorrhea (P = .05) were more common in the toremifene group. The number of subsequent second cancers was similar. The breast cancer recurrence rate was 23.1% (n = 106) in the toremifene group and 26.1% (n = 115) in the tamoxifen group (P = .31). When only patients with estrogen receptor (ER)–positive cancer were considered (n = 556), the risk for breast cancer recurrence was nonsignificantly lower among the toremifene-treated women, with a hazards ratio of 0.74 (90% confidence interval, 0.52 to 1.04; P = .14). The mean time to breast cancer recurrence and overall survival were similar in both groups. CONCLUSION: The side-effect profile of toremifene resembles that of tamoxifen. The efficacy of toremifene seems to be no less than that of tamoxifen. The trend for fewer breast cancer recurrences in the ER-positive subgroup is encouraging, but a longer follow-up is needed to confirm this.

171 Background: Oncotype DX Score is a 21-gene expression analysis that has been validated clinically as a reliable predictor of breast cancer recurrence for ER-positive, node-negative breast cancers. Obesity is recognized as a risk factor for many cancers, including breast cancer. Additionally obesity has been shown to be an independent prognostic factor in breast cancer. The primary objective of this study is to determine the correlation between obesity and Oncotype DX score, hence the relationship between obesity and breast cancer recurrence in ER-positive breast cancer. The secondary objective is to investigate the association between weight gain after diagnosis and breast cancer recurrence. Methods: An IRB-exempted retrospective chart review of female patients at Wellspan Group with ER-positive breast cancer who had Oncotype DX analysis in 2008 and 2009. Data collected included Oncotype DX score and BMI (at diagnosis, 6 months and 12 months). Data were analyzed to determine the correlation between Oncotype DX score and BMI at diagnosis, at 6 months and at 12 months. The correlation between Oncotype DX score and BMI changes at 12 months also was determined. Results: A total of 125 patients were identified; 103 had BMI recorded at diagnosis, 88 had BMI recorded at 6 months and 87 had BMI recorded at 12 months. Of these, we were able to determine the BMI changes at 12 months for 82 patients. The Pearson correlation scores were 0.091 (p = 0.361), 0.074 (p = 0.492), and 0.047 (p = 0.669) for BMI at diagnosis, at 6 months and at 12 months respectively. The Pearson correlation score was 0.007 (p = 0.948) for BMI changes at 12 months. Conclusions: Obesity and weight gain are not independent predictors of recurrence in patients with ER-positive breast cancer. The reported adverse prognostic associations may be more prominent in ER-negative breast cancers. This is consistent with the reports suggesting a higher rate of ER-negative, high-grade cancers in obese women as well as a greater magnitude of benefit from dietary and weight reduction interventions seen in women with ER-negative cancers.

Purpose: Increasing numbers of older women are affected by early breast cancer, because of prolonged life expectancy and the increasing incidence of breast cancer with age. The role of adjuvant therapy for this population is still a matter of debate. We reviewed the long-term outcome of a mature trial comparing endocrine treatment versus no adjuvant therapy in older women with node-positive breast cancer. Patients and Methods: From 1978 to 1981, 349 women 66 to 80 years of age with pathologically involved lymph nodes after total mastectomy and axillary clearance were randomly assigned to receive 12 months of adjuvant tamoxifen plus low-dose prednisone (p+T) or no adjuvant therapy. Three hundred twenty patients were eligible. Results: At 21 years’ median follow-up, 1 year of p+T significantly prolonged disease-free survival (DFS; P = .003) and overall survival (P = .05; 15-year DFS, 10% ± 3% v 19% ± 3%; hazard ratio, 0.71; 95% CI, 0.58 to 0.86). When comparing competing causes of failure (breast cancer recurrence and deaths before breast cancer recurrence), p+T was far superior in controlling breast cancer recurrence (P = .0003), but the improvement was seen mainly in soft tissue sites. Conversely, patients in the p+T group were more likely to die before a breast cancer recurrence (P = .03). Conclusion: This trial demonstrates that significant treatment benefits continue to be observed in older patients treated for 1 year with p+T. Despite issues relating to competing causes of failure, older breast cancer patients can benefit from treatment and should be considered for trials of adjuvant systemic therapy.
