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

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.
