Abstract
Survival studies may serve as benchmarks to develop cancer-related policies and estimate baseline survival rates in a given patient population. We carried out a retrospective audit of cases managed in 2009 and now report the disease-free survival (DFS) in early breast cancer (EBC) and locally advanced breast cancer (LABC) in patients registered at a tertiary cancer center in India. The study included 2192 patients with breast cancer with ages ranging from 18 years to 94 years with a median of 50 years. Of these, 888 (40.5%) were EBCs Stage I and II, 833 (38%) were LABCs (Stage III), and 471 (21.5%) were de novo metastatic or relapsed cancers at presentation. The 5-year DFS in the women with EBC was 85.5% and in LABC, it was 67.7%, P < 0.001. The factors adversely affecting DFS in EBC were node metastasis (P < 0.001), higher metastatic nodes (P < 0.001), hormone receptor negativity (P = 0.001), and human epidermal growth factor receptor 2 (Her2neu) positivity (P = 0.033). In the multivariate Cox regression analysis in EBC, node-positive status (hazard ratio [HR] 2.28, 95% confidence interval [CI] 1.51-3.45, P < 0.001) and hormone receptor negative tumors (HR 1.96, 95% CI 1.30-2.94, P = 0.001) significantly affected DFS in EBC.
