Abstract

Verrucous carcinoma of oral cavity is a highly well differentiated variant of squamous cell carcinoma with a low potential for invasion and metastasis. It is prevalent in the tobacco quid chewing population in our region. In this observational study, we reviewed the medical case records of 58 patients treated for oral verrucous carcinoma staged T2 to T4a. All patients underwent wide excision of tumour which included marginal mandibulectomy in 22 and hemimandibulectomy in 23 patients along with neck dissection saving the accessory nerve and internal jugular vein. 5 patients were found to have bone involvement along the alveolar sockets. 11 patients had other associated premalignant lesions in oral cavity. Only 2 patients had lymph node metastasis without extra nodal spread in submandibular region. With a mean follow up of 6 years and minimum follow up of 1 year, 3 patients had local recurrence. All these 3 patients had bone involvement and 2 of them had lymph node metastasis on histopathological examination. 3 patients who had associated premalignant lesions developed second primary in oral cavity after 3 years. In our experience, verrucous carcinoma has good prognosis when treated by surgery. Bone involvement along alveolar sockets and associated oral premalignant lesions adversely affect the outcome. There was no difference in the outcome between selective and modified radical neck dissection. Therefore selective neck dissection (supraomohyoid) would be adequate in treating these patients. Adjuvant radiotherapy can be reserved for T4a lesions or for positive margins.
