Background & objectives: Tumour infiltrating lymphocytes (TILs) represent the host immune response against cancer cells associated with good or bad prognosis in different tumour types. This study was undertaken to evaluate the significance of CD3+, CD4+ and CD8+ TILs in breast cancer tissues in relation to clinico-pathological variables and survival outcome. Methods: Immunohistochemistry (IHC) was performed with antibodies against CD3, CD4 and CD8 antigens on formalin-fixed paraffin-embedded tissue sections of 150 breast cancer patients. Intratumoural and stromal TIL counting was performed semiquantitatively. Results: The higher CD3+, CD4+ and CD8+ intratumoural and stromal counts showed independent and direct association with good prognosis. The prognostic predictor value of intratumoural counts was higher than stromal counts. The independent associations of intratumoural and stromal counts became more prominent when adjusted with stage and grade, respectively. Among intratumoural counts, the high (++/+++) CD4+ count (OR=3.85, 95% CI=3.28-16.71, P
