Tracheobronchial mucoepidermoid carcinoma. Clinicopathological features and results of treatment.

摘要: Mucoepidermoid carcinomas of the tracheobronchial tree are extremely uncommon and, as a result, opinions regarding their natural history conflicting. In an effort to determine whether tumors aggressive or relatively benign, we have collected seven well-documented, previously unreported cases from among 4,250 primary pulmonary and 116 bronchial adenomas. The two tracheal five endobronchial lesions presented here include one high-grade six low-grade tumors. Curative resections were performed, including segmental in patients, lobectomy three pneumonectomy follow-up is complete time this report. Long-term survivals ranging 5 23 years, averaging 12.8 been achieved patients with carcinoma. variant proved fatal within 28 months diagnosis despite surgical attempts at control radiotherapy. It concluded that these exhibit spectrum virulence amenable long-term cure. optimum treatment remains problematical.
