End Results of Surgical Treatment of 622 Cases of Tumors of the Salivary Glands.

Abstract

Surgery was performed on 622 patients with tumors of the salivary glands from 1929 to 1972; the gland affected was the parotid in 527 cases, the submandibular glands in 50, and minor salivary glands of palate and other sites in 45. The analysis of distant results point out that both for benign and malignant tumors total sialoadenectomy must be the treatment of choice, as demonstrated by the high rate of recurrence after local excision or partial resection of the gland, even in cases of surely benign lesions such as mixed tumors. It is worthy of being quoted the high rate of recurrence from cylindromas, especially of the palate (48.5%), after surgical removal. As to malignancies of parotid and submandibular glands 5-years survival rates after radical surgery were of 52 % and 30 % respectively.
