e11020 Background: Aromatase inhibitors (AIs), anastrozole (ANA) and letrozole (LET), have been shown to be more effective than tamoxifen in the adjuvant treatment of postmenopausal hormone receptor positive breast cancer. However, data from preclinical studies and subgroup analyses of some major clinical trials suggest differring efficacy among AIs. Yet the best clinical choice is still not very clear. This retrospective study aims at comparing the results of treatment with either AI among different subgroups of patients, especially among the obese patients. Methods: Between 2006-2011, 335 women with stage I to IIIC hormone receptor positive postmenopausal breast cancer treated with either ANA or LET as adjuvant treatment were included. Body mass index (BMI), estrogen and progesterone receptor (ER and PR) and HER-2 status at the time of diagnosis were recorded. Patients were grouped as BMI ≤ 30 and BMI > 30. The Kaplan-Meier survival estimates were calculated. Subgroups were compared with the log rank test. A 5 % type-I error was used to infer statistical significance. Results: The percentage of patients receiving ANA or LET were 47.2% and 57.8%, respectively. Median age at diagnosis was 58 (42-84) and lower in the ANA group (p=0.04). Stage II to IIIC disease was present in 76.8 % and the distribution was similar between ANA and LET (p=0.84). Median time of follow-up was 29 months (6-124) and median duration of hormonotherapy was 29 months (3-68) and similar between two groups (p=0.52 and p=0.55, respectively). Of the patients 41.2 % had a BMI of > 30. There was no significant difference in overall (OS) and progression-free (PFS) survivals between ANA and LET (p=0.08 and p=0.94, respectively). However, among patients with a BMI of > 30 a statistically insignificant benefit in PFS was observed with LET (p=0.1). ER, PR and HER2 status had no significant impact on OS and PFS. Conclusions: In a median follow-up of 29 months letrozole and anastrozole yielded similar OS and PFS. However, among patients with a BMI of > 30, LET might bring about a PFS advantage. In selected obese patients LET might be a reasonable choice in this setting. Larger studies with long term follow-up are needed to reach an exact conclusion.

Abstract Background The standard adjuvant endocrine treatment for postmenopausal female patients with hormone receptor positive early breast cancer was 5 years of tamoxifen, but recurrence and side effects restrict its usefulness. The aromatase inhibitor (anastrozole or exemestane or letrozole) was compared with tamoxifen for 5 years or started after completing 2-3 years of tamoxifen in postmenopausal female patients diagnosed with early breast cancer at "Ain Shams University Hospitals" Objective The aim of the study was to measure survival outcome and treatment tolerability for postmenopausal females with Hormone Receptor Positive early breast cancer who received adjuvant hormonal treatment with tamoxifen [TAM] only for 5 years versus those who received adjuvant hormonal treatment with tamoxifen [TAM] for 2 years switching to aromatase inhibitors [AI] in the sequential 3 years versus those who received adjuvant hormonal treatment with aromatase inhibitors [AI] solely for 5 years. Patients and methods This study included 100 postmenopausal women with early breast cancer who presented at the Clinical Oncology Department, Ain Shams University, in the interval from January 2010 until December 2015. Conclusion Similar disease free survival and overall survival were observed among the three studied groups. Switching tamoxifen to aromatase inhibitors provides better tolerability in terms of endometrial thickness when compared to 5 years of tamoxifen monotherapy. Patients who administer aromatase inhibitor included in the switching strategy experience less osteoporosis and less generalized bone pain compared to upfront aromatase inhibitor to 5 years. There was a significant improvement of disease free survival (DFS) in human epidermal growth factor receptor 2 (HER 2) negative patients receiving any adjuvant hormonal treatment line for five years in comparison to HER 2 positive patients receiving the same adjuvant hormonal treatment for five years.

Background: Aromatase inhibitors (AIs) represent an effective endocrine treatment for hormone receptor-positive postmenopausal breast cancer patients with early stage or metastatic disease.Objective: Assessment of Cardiotoxicity in Hormone positive Postmenopausal Breast Cancer Patients receiving AIs (upfront orswitch therapy).Methods: This cross sectional study included 123 postmenopausal breast cancer patients presented to the Clinical Oncology Department, Ain Shams University (Cairo, Egypt) in the interval from August 2016 to June 2017 with hormone receptor positive receiving Aromatase Inhibitors, To assess cardiotoxicity in these patients, they were subjected to blood pressure and lipid profile measurement, electrocardiography (ECG), and electrocardiography (ECHO) and classified into patients had Nolvadex then A.I (arm 1) and others had upfront A.I (arm 2).Results: The age of patients ranged from 41 years to 85 years with mean age of 61 years. Seventy one patients (57.7%) showed cardiotoxicity as assessed by ECHO. They showed significant correlation with rising age above 62 years, IHD, history of HTN and DM (p value: .001, .001, .017 and 0.035 respectively). However, correlation between cardiotoxity and blood pressure changes, lipid profile changes and ECG findings and ECHO changes in switch therapy and upfront A.I were not statistically significant (p value = .275, .116, .081 and .761 respectively).Conclusion: Assessment of cardiotoxicity in hormone positive postmenopausal breast cancer patients receiving Aromatase Inhibitors showed evidence of cardiotoxicity in half the patients (57.7%) as detected by ECHO only. They showed statistically non significant correlations either recievied switch therapy or upfront A.I.
