[Neck adenopathies in epidermoid carcinomas of the piriform sinus: a retrospective study and 5-year survival]

Retrospective survey done with 27 patients of epidermoid carcinoma of the piriform sinus in order to ascertain the degree of regional spread--both clinic and histologic--of the neoplasm and also set up the relation between the actual adenopathies, the rate of recurrences and the actuarial survival at 5 years post-treatment term. The checked results show the bad prognosis of such tumors irrespective of the most aggressive surgery (partial hemipharyngectomy plus total laryngectomy plus neck dissection and postoperative X-ray therapy). The actuarial survival accounts for 29.6 percent after 5 years. The AA. confirm a great lymphophile tendency with an invasion percentage amounting to 55.6 percent but with a certain clinic-histologic disagreement. Relation between the frequency of adenopathies (clinical and histological), the survival and the recurrences at 5 years is indicative to a great extent that adenopathies are a pejorative circumstance of these neoplasms.
