The present analysis reports the clinical, pathological, treatment profile and overall survival (OS) and disease-free survival (DFS) outcomes of consecutive breast cancer patients from three Indian centres, who underwent curative surgery as their first treatment. Among the 3453 patients, stage I, II, and III cases were 11.75%, 66.79%, and 21.64%, respectively while hormone receptor positive/HER2 negative, triple negative (TNBC) and hormone receptor any/HER2 positive cases were 55.2%, 24.2% and 20.6%, respectively. The five-year OS in the entire cohort, node-negative and node-positive patients were 94.1% (93.25-94.98), 96.17% (95.2-97.15) and 91.83% (90.36-93.31), respectively, and the corresponding DFS were 88.1% (86.96-89.31), 92.0% (90.64-93.39) and 83.93% (82.03-85.89), respectively. The five-year OS in hormone receptor positive/HER2 negative, TNBC and HER2 subgroups were 96.11% (95.12-97.1), 92.74% (90.73-94.8) and 90.62% (88.17-93.15), respectively, and the corresponding DFS were 91.59% (90.19-93.02), 85.46% (82.79-88.22) and 81.29% (78.11-84.61), respectively. This is the largest dataset of early breast cancer patients from India with survival outcome analysis and can therefore serve as a benchmark for future studies.
