MedicalResearch.com Interview with: Dr. R.A. Badwe, MS Director,  Tata Memorial Centre E. Borges Marg, Parel Mumbai 400 012 MedicalResearch.com: What are the main findings of the study? Answer: The trial was a randomized control study involving 350 women with per primum metastatic breast cancer. These women were divided into two groups from February 2005 to May 2013. One group underwent surgery and radiotherapy (LRT) (n=173) while another group of 177 women were spared these (no LRT). Both groups had undergone six successful rounds of chemotherapy before their recruitment into the trial. Women who underwent surgery had the primary breast tumour and lymph nodes removed, followed by locoregional radiation therapy. The primary endpoint of the study was overall survival (OS). At a median follow-up of 17 months, no difference was observed in OS between the groups; the OS rates were 19.2% and 20.5%, respectively, (HR = 1.04; 95%CI, 0.80-1.34; P = 0.79).  The lack of a survival benefit is due to a trade-off between local control and distant disease progression. The results indicated that women who underwent surgery and had improved locoregional control and significantly worse distant progression-free survival compared with women who did not undergo surgery (HR = 1.41; 95% CI, 1.08-1.85; P = .01). Progression of distant disease was 42% more likely (P = .01) in the LRT arm whereas the risk of local progression was 84% lower with LRT. (more…)
