Abstract
Objectives The frequency of oral squamous cell carcinoma in young adults has increased in the last decades and there are conflicting results in literature about its prognosis in young subjects. The aim of this study was to analyze the clinical and pathological features of oral squamous cell carcinoma in a cohort of young adults in order to investigate the presence of new independent prognostic markers. Materials and Methods Only HPV‐negative young patients (under 40‐year‐old) affected by oral squamous cell carcinoma, were considered in this study. Clinical and pathological data were collected. Patients were re‐staged according to the 8th edition of AJCC. Results Overall, 66 patients were considered in this study. Perineural invasion significant correlated with both 7th and 8th edition of AJCC, and lymphovascular invasion (p‐value < 0.05). The multivariate survival analysis showed that patients with perineural invasion had a significant worse prognosis (HR = 6.384 95% C.I. 1.304‐31.252; p‐value = 0.022). Conclusions Perineural invasion emerged as an independent prognostic factor for disease‐specific survival in young patients with oral squamous cell carcinoma. Furthermore, the evaluation of this parameter is simple, inexpensive and can be used to augment the risk stratification of oral cancer based on the 8th edition of AJCC.Keywords
