Therapeutic management of laryngeal cancer. Results of a study of 356 patients from the Cancer Registry of the Somme, France

Abstract

Conclusions. The global survival rate was low compared to those reported in the literature, in which the analyzed populations were selected according to the tumor stage or treatment. This study should be prolonged and should also involve other cancer registries in France in order to increase the number of patients and to analyze tumors of comparable stage and therapeutic management. Objective. To analyze the survival rate of a non-selected laryngeal cancer population from the Cancer Registry of the Somme, a French region. Material and Methods. A total of 356 patients were included in a retrospective study covering the period 1987–1997. Survival and prognostic factors were analyzed. Statistical analysis was performed using the Kaplan–Meier method, the Cox model and the χ² test. Results. The 5-year global survival rate was 42% for males and 55% for females. Tumor localization, T, N and M stages and surgery were found to be significant prognostic factors. Sex and age were not statistically significant factors. For stage I tumors, surgery alone gave better results than radiotherapy alone in terms of global survival. No difference occurred in terms of local recurrence. A similar comparison was not possible for stage II–IV tumors owing to the small number of cases.
