Abstract

Surgery is the primary modality for the treatment of early oral cancer. The present study aims to evaluate the oncological outcomes, patterns of failure, and prognostic predictors of recurrence in patients of early oral cancer (Stage I and II) treated by surgery alone. It is a single institutional, observational retrospective cohort study conducted from 2012 to 2017.The study was approved by institutional ethics committee. All consecutive patients who underwent upfront curative surgery alone (wide excision of tumour + neck dissection) for pathologically proven early oral cavity SCC(Squamous Cell Carcinoma) pT1-2N0 were included in the study. 113 patients were included in the study after a median follow-up of 58.2months. The median age was 58.5years. 25 patients were stage I, and 88 patients were stage II. The most common subsite was buccal mucosa. There were 31 recurrences and 24 deaths. Using Kaplan Meier method, 3 and 5year overall survival was 92% and 71.8%, respectively, while 3year and 5year recurrence-free survival was 77.9% and 69.4%, respectively. Perineural invasion and poor differentiation affected recurrence-free survival significantly (p value < 0.05). More than one-fourth of surgically treated early oral SCC patients developed recurrence. Presence of poorly differentiated histology and the perineural invasion were the high risk factors which hampered the recurrence free survival. High consumption of betel quid consumption in this part of the world leads to differences in the involved subsite from the Western literature. Adding adjuvant treatment in the presence of these adverse histopathological features may improve prognosis. Randomised studies are warranted to answer this dilemma. Level of Evidence IV.
