There are many established and novel prognostic indices described for breast carcinoma (BCa). We aimed to study prognostic indices for BCa derived from routine clinical, histopathological and immunohistochemical data in the local setting and to evaluate their impact on short-term overall survival(OS) and disease free survival(DFS). Methodology Bidirectional cohort study included 174 BCa patients at National Hospital of Sri Lanka, from 2012-2014, excluding post-neo-adjuvant chemotherapy cases. Clinical details, tumour size and nodal status were obtained from histopathology records. Histopathological parameters, oestrogen and progesterone receptors and HER2 status were reviewed. Molecular subtype, nodal ratio (NR=number of positive nodes/total number retrieved) and Nottingham prognostic index (NPI) were determined. Follow up data (1½months-4 years) were obtained. Data was analyzed by life tables and Cox regression using SPSS 16.0. Results Mean age was 56.5 years (29-87years) and mean follow-up duration was 27.3 months(SD=8.68). Of the study group 148(85.1%) remained disease free, 10(5.7%)survived with metastasis, 4(2.3%) survived with recurrences and 12(6.9%) succumbed. Duration of breast lump Discussion and conclusion Stage, nodal ratio and lymphoid infiltrate were predictive of short-term survival similar to other studies. Exclusion of advanced cases possibly contributed to lack of significance of other prognostic factors. Breast lump duration, tumour, nodal and TNM stages and nodal ratio were predictive of both overall survival and disease free survival, with tumour stage being predictive on both univariate and multivariate analysis. Lymphoid infiltrate at tumour periphery was predictive of overall survival.
