Clinical Study of Adenoid Cystic Carcinoma of the Salivary Glands

타액선에 생긴 선낭암의 임상적 고찰

After analysis according to age, sex, site of origin, nodal involvement, perineural invasion. histopathology and treatment modality. authors had reached the following conclusion about the 28 cases of adenoid cystic carcinoma of the salivary gland, which were, histopathologically, diagnosed at Yonsei University Severance Hospital and Yongdong, Severance Hospital during the 8-year period from Apr. 1983 to Mar. 1991. Among the 28 cases, 13 were females and 15 were males, which implies that there isn't any sigificant distinction of gender. The age range was 24 years to 69 years with a mean age of 49 years, and the most common site of origin in order was 6 cases(21.4%) of maxillary sinus, 5 cases(17.8%) of submandibular gland, each 4 cases(14.4%) of parotid gland, palate, 3 cases(10.4%) of nasal cavity and each 2 cases(7.1%) of mouth floor, nasopharynx with each one case(3.6%) of buccal mucosa and retromolar trigone. With clinical staging by UICC, the 5-year survival of adenoid cystic carcinoma was 100% in stage I and II, 87.5% in stage III. In stage IV, all of the patient were died within 3 years. We have known that the prognosis was poorer in following cases; the cases with higher clinical stage, primary site other than the major salivary gland especially maxillary sinus and positive neural or nodal invasion.
