Résumé
Purpose: Squamous cell carcinomas of the oral cavity occurring in young people represent a specific entity. Its management and prognosis are controversial. We performed a retrospective chart review of all patients aged less than 40 years old and treated at Gustave-Roussy Cancer Centre for a squamous cell carcinomas of the oral cavity between 1999 and 2011. Methods: Patients and tumour characteristics, type of treatment and follow-up data were collected. Survival data were analysed according to the methods of Kaplan-Meier and both univariate and multivariate analyses were performed to look for prognostic factors regarding overall survival and progression-free survival. Results: Sixty-three patients were identified. Median follow-up was 64 months. Most of the tumours were initially located in the mobile tongue (n = 54, 85.7%). Overall 17 patients had died, including 15 from the treated cancer. Overall and progression-free survival rates at 5 years were respectively 79.6% and 68.6%. The corresponding 5 years local, regional and metastatic relapse free survival rates were 80%, 91% and 89% respectively. In the multivariate analysis only the absence of initial surgery (hazard ratio [HR]: 13.5 [2.0; 90.5]; P = 0.007) was prognostic for overall survival, while alcohol abuse (HR: 0.37 [0.15; 0.9]; P = 0.03) and the absence of surgery (HR: 13.6 [2.5; 74.2]; P = 0.002) were associated with a decreased progression-free survival. A younger age (less than 30 year old) was not associated with the risk of recurrence or death. Conclusion: Survival rates and tumour control probabilities are relatively high among young patients suffering from squamous cell carcinomas of the oral cavity treated at a tertiary centre. The early identification of patients at risk of relapse is currently difficult. The balance between recurrence and treatment toxicity warrants further studies, both on the clinical level and for the development of prognostic biomarkers.
