Background: Breast cancer is the most common malignancy in women worldwide. Patients with American Joint Committee on Cancer Stage III breast cancer have been noted to have good response to neoadjuvant chemotherapy. The aim of this study is to evaluate survival of such patients after treatment at our hospital. Methods: A 5-year prospective study was conducted between January 2009 and December 2013. Patients had four courses of neoadjuvant chemotherapy (cyclophosphamide, adriamycin, paclitaxel), Auchincloss' modified radical mastectomy, two courses of adjuvant chemotherapy and adjuvant tamoxifen (premenopausal) or letrozole (post-menopausal) for ER-positive tumours. All patients had radiotherapy. Follow-up was on outpatient basis and through phone calls. Statistical analysis was done using SPSS version 21.0, survival analyses with Kaplan–Meier method, multivariate analyses done with P ≤ 0.05 regarded as statistically significant. Results: Data from 303 patients (291 females and 12 males) were analysed. One-year, 2-year, 3-year, 4-year and 5-year disease-free survival (DFS) was 79.80%, 56.57%, 51.51%, 47.47% and 47.47%, respectively. One-year, 2-year, 3-year, 4-year and 5-year overall survival (OS) was 80.80%, 61.61%, 55.56%, 51.51% and 51.50%, respectively. Initial tumour size, response to neoadjuvant chemotherapy, number of involved nodes, tumour grade and receptor status had statistically significant relationship with DFS and OS. The relationship between the patients' age, gender and both DFS and OS was not statistically significant. Conclusion: Five-year DFS and OS were 47.47% and 51.50%, respectively. Initial lesion size, response to therapy, involved nodes, tumour grade and receptor status had statistically significant relationship with DFS and OS.
