FATORES PREDITORES DE MARGEM POSITIVA APÓS RESSECÇÃO CIRÚRGICA DE CARCINOMA DE CÉLULAS ESCAMOSAS CUTÂNEO EM CABEÇA E PESCOÇO

Abstract

Cutaneous squamous cell carcinoma is a neoplasm of great epidemiological relevance in the world and can be cured, depending on it's stage and the characteristics of the patient. Positive margins after excision is an important prognostic factor in these patients, and may result in recurrence rates of up to 50%. We aim to suggest possible associations between anatomopathological features and positive histopathological margins after surgery for excision of Head and Neck Cutaneous Squamous Cell Carcinoma. METHODS: We performed an observational and crosssectional study, involving patients who underwent excision of Head and Neck Cutaneous Squamous Cell Carcinoma at a reference hospital in Paraiba. The following variables were analyzed: lesion topography, pathological features (degree of differentiation, tumor size, degree of infiltration, angiolymphatic or perineural involvement, positive surgical margins) and tumor staging T. RESULTS: A total of 242 anatomopathological reports were considered eligible and 34 had a positive surgical margin (14%). The anatomopathological characteristics studied did not show a statistically significant association with the involvement of surgical margins. CONCLUSIONS: The anatomopathological characteristics studied do not seem to be related to incomplete excision of head and neck cutaneous squamous cell carcinoma.
