Abstract:Background: A prospective randomised trial was undertaken to evaluate the role of neoadjuvant chemoendocrine therapy prior to surgery in primary operable breast cancer. Patients and methods: Three hundred nine women (median age 56 years, range 27-70) with primary operable breast cancer confirmed on fine needle aspiration (FNA) cytology were recruited to this study. They were treated with a combination of mitozantrone and methotrexate (+ mitomycin-C) combined with tamoxifen (2MT). Patients received eight cycles of 2MT (four prior to surgery in the neoadjuvant group) and tamoxifen for five years with appropriate surgery and radiotherapy. The two groups were comparable for age, menopausal status, stage and surgical requirements. Results: The clinical response rates to neoadjuvant therapy were as follows: 22% complete response (CR), 29% minimal residual disease (MRD), 33% partial response (PR), 15% no change (NC) and only two patients had clinical evidence of progressive disease. Surgical requirements were reduced from 31 patients (22%) of the adjuvant group having mastectomy to 14 (10%) in the neoadjuvant group (P < 0.003). At a median follow-up of 48 months (range 10-70 months) there is no statistically significant difference between the two groups in terms of local relapse, metastatic relapse or overall survival. Symptomatic and haematologic acute toxicity was low and similar for adjuvant and neoadjuvant therapy. Conclusion: This randomised trial has shown a significant reduction in the surgical requirements for mastectomy, after treatment with neoadjuvant chemoendocrine therapy, with no deterioration in local or distal relapse.
