Lip and oral cavity cancer remains the most common cancer among Indian males and third most common cause of cancer-related deaths in India. Cervical lymph node metastasis is one of the most important prognostic factors in oral cavity cancer. The aim of present study was to estimate the prevalence of nodal involvement and analyse patterns of nodal metastasis in oral cavity cancer patients.This prospective observational study was conducted between January 2019 and June 2020. Patients of oral cavity squamous cell carcinoma undergoing surgery with simultaneous neck dissection were included. Data pertaining to the clinical profile, treatment and histology details were collected and analysed.A total of 63 patients were included in present study. Out of 63 patients, unilateral neck dissection was performed in 47 (75%), while 16 (25%) underwent bilateral neck dissection. Overall clinical and pathological nodal positivity rates were 75% and 52%, respectively. Level I (48%) followed by IIa (20%) were most commonly involved stations. Combined involvement of level IV and V was seen in only 5%, and no skip metastasis was reported in level IV and V.Level I and II are the most commonly involved stations in oral cavity squamous cell carcinoma (SCC). Oral SCC has a predictable nodal spread pattern with no skip metastasis to level IV/V noted in present study. There is a need for good quality randomised control trials to optimise the treatment protocols in clinically node-positive patients with respect to level IIB and V dissection.
