[Cancer of the hypopharynx and cervical esophagus. Role and limits of the surgical treatment].

From 1975 to 1988, we observed 169 patients with a carcinoma of the cervical esophagus, 85 with a carcinoma involving the hypopharynx and the cervical esophagus, and 27 with a carcinoma of the cervical esophagus occurring after laryngectomy for laryngeal carcinoma. The average age was 57.5 years (41-73). Exploration was surgical for 167 patients (operability ratio 59.5%), and the lesion was resected in 152 cases (resectability ratio 81.1%). Resection was complete in 129 patients (84.5%) and palliative in 23 (14.5%). A laryngopharyngoesophagectomy involving the cervical esophagus and requiring the transplantation of a free intestinal loop was performed in 33 cases, with an operative mortality rate of 6.1%. Pharyngolaryngectomy with total esophagectomy was performed in 101 patients, and the digestive tract was reconstructed by means of pharyngogastrostomy or pharyngocolostomy (respectively 85 and 16 cases) with an operative mortality rate of 12.9% and 18.3%, respectively. Complete esophagectomy without laryngectomy was performed for 18 patients with carcinoma of the distal cervical esophagus who refused laryngectomy, the hospital mortality rate being of 5.5%. The actuarial survival rate after 5 years (not including operative mortality) was 15.8%. Better results were achieved after complete resection for carcinoma of the hypopharynx than for carcinoma of the cerebral esophagus. The actuarial survival rates after 2 and 5 years were 59% vs. 26% and 43% vs. 17% respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
