Knowledge of the prognostic factors of squamous cell carcinoma of the head and neck is of great importance, as they help to predict the future evolution of the disease and to understand facts about its pathophysiology, they also allow comparing treatments, grouping patients with a similar prognosis, designing trials clinicians even select the ideal treatment for each patient. An observational, descriptive, longitudinal and retrospective study was carried out with the objective of evaluating the impact of perineural invasion in patients with tongue cancer treated at the Institute of Oncology and Radiobiology (INOR) with a universe of 62 patients. Variables such as: age, sex, skin color, histological grade, clinical stage, type of lesion, surgical technique used and major prognostic factors were taken into account. Two groups were established, one without the presence of perineural invasion and the other with perineural invasion. The highest number of cases occurred in the 55-64 age group in both groups, with a higher incidence of males and white skin color. Well-differentiated squamous cell carcinoma prevailed in both groups with 54.3% and 50.0. The surgical technique most used in the group of patients with the presence of perineural invasion was partial glosectomies plus selective neck dissection, positive surgical section margins were the most frequent major prognostic factor in patients with perineural invasion with 56.3% and statistical significance p = 0.021. Relapses, local, regional and distant, were present in all patients who presented statistically significant perineural invasion p = 0.010.
