Abstract
Management of locally advanced OSCC include primary surgery followed by adjuvant radiotherapy or chemo radiation, concurrent chemo radiation, induction chemotherapy followed by surgery or non surgical methods. In resectable disease the role of induction chemotherapy is questionable and surgery remains the first choice. In this study we aimed at evaluating the survival and factors effecting survival in locally advanced oral cancer. retrospective review of patient records was made. Kaplan Meir method was used to evaluate OS and DFS rate and log rank test was used to compare the survival amongst groups. Cox regression analysis (univariate and multivariate) was used to evaluate the hazard ratio to find out the possible factors influencing risk of death and disease. The 3�year OS of the entire cohort was 56.80% and 3�year DFS was 52.4%. ECS, surgical margin, PNI, LVI and LN size were independent risk factors for poor overall and disease free survival. We identified ECS, positive margin, LVI, PNI and LN size as independent risk factors effecting survival. These factors justify the use of adjuvant radiotherapy or chemo radiation according to the already available guidelines. � 2022, Association of Otolaryngologists of India.
