Supracricoid laryngectomy with cricohyoidoepiglottopexy (CHEP) in the management of laryngeal carcinoma: oncologic results. A 35-year experience.

ABSTRACT

To evaluate the long-term oncologic results of supracricoid laryngectomy with cricohyoidoepiglottopexy (CHEP) for laryngeal cancer. A 35-year retrospective study concerning 291 patients treated by supracricoid laryngectomy with CHEP for laryngeal cancer was performed. The following postoperative data were studied recurrence rates (lymph node and laryngeal), distant metastases and second cancer. The mortality rate and overall survival were estimated by the Kaplan-Meier method. The postoperative mortality was 1.03 %. 23 patients were lost to follow-up. The 3-year survival rate was 84 % and the 5-year survival rate was 80 %. 12 patients developed distant metastasis. 31 patients developed a second cancer. The local (laryngeal) control rate was 93.94 % and the regional (cervical lymph node) control rate was 92.05 %. In multivariate analysis, the occurrence of a second non-ENT cancer and metastasis as well as margins involvement were reliable to mortality. Supracricoid laryngectomy with CHEP appears to be associated with very good long-term oncologic results and still has a place in the management of T1, T2 and selected T3 glottic cancers.
