PURPOSE To compare 1 year of therapy with continuous cyclophosphamide, methotrexate, fluorouracil (5-FU), vincristine, and prednisone (CMFVP) with a short course of treatment with a doxorubicin-based regimen in the postsurgical adjuvant treatment of patients with hormone receptor-negative, node-positive breast cancer. PATIENTS AND METHODS Five-hundred thirty-one eligible women with hormone receptor-negative, node-positive breast cancer were randomized to receive either 1 year of therapy with CMFVP or 20 weeks of therapy with four 5-week courses of treatment with 5-FU, doxorubicin, cyclophosphamide, and methotrexate (FAC-M). RESULTS At a median follow-up time of 4.9 years, the two treatment arms cannot be demonstrated to be different with respect to overall survival (stratified log-rank, P = .27). The 5-year survival rate is 64% on the CMFVP arm and 61% on the FAC-M arm. CMFVP produces marginally superior disease-free survival (P = .06). The estimated 5-year disease-free survival rate is 55% for patients treated with CMFVP as opposed to 50% for patients treated with FAC-M. CONCLUSION Neither regimen was shown to be superior in terms of overall survival. Because the disease-free survival produced by CMFVP is marginally superior to that produced by FAC-M, we do not recommend FAC-M for further investigation or for routine use. Possible implications of this study are discussed in the context of other adjuvant chemotherapy trials.

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.

Purpose The optimal adjuvant endocrine strategy for postmenopausal breast cancer is unknown. Options include the antiestrogen tamoxifen, estrogen deprivation with aromatase inhibitors, and sequential therapy with tamoxifen and then an aromatase inhibitor. Methods We developed Markov models to simulate 10-year disease-free survival among postmenopausal women with hormone receptor–positive breast cancer. The treatment strategies analyzed were 5 years of tamoxifen alone, 5 years of an aromatase inhibitor alone, and sequential treatment consisting of tamoxifen with cross over to an aromatase inhibitor at 2.5 or 5 years. Risk estimates were derived from reported randomized clinical trials. Results Sequential therapy with tamoxifen followed by cross over to an aromatase inhibitor at 2.5 years yielded a modest improvement in disease-free survival compared with planned aromatase inhibitor monotherapy. At 10 years, the cross-over strategy yielded absolute disease-free survival rates of 83.7% and 67.6% for node-negative and node-positive patients, respectively, compared with 82.6% and 65.5%, respectively, for aromatase inhibitor monotherapy, which is a 6% relative risk reduction. Sequential therapy improved disease-free survival estimates by year 6 after treatment initiation. Later cross over from tamoxifen to an aromatase inhibitor at 5 years did not further improve 10-year disease-free survival estimates. Sensitivity analyses suggest that sequential treatment strategies optimized 10-year disease-free and distant disease–free survival independent of the degree of the beneficial carryover effect after aromatase inhibitor therapy or the ratio of local to distant tumor recurrence. Conclusion Modeling estimates suggest that sequential adjuvant therapy with tamoxifen followed by an aromatase inhibitor after 2.5 years yields improved outcomes compared with either drug alone or cross-over treatment after 5 years of tamoxifen.
