Second, third, and fourth head and neck tumors. A progressive decrease in survival

Abstract

Background Patients with a first head and neck carcinoma have a high risk of successive neoplasms, many of which appear again in the head and neck. Second head and neck tumors have a poorer prognosis than first tumors, but data about the prognosis of third and fourth tumors in the head and neck are lacking. Methods We carried out a retrospective study of 4298 patients with a primary head and neck carcinoma. Survival and the characteristics of the first tumor, second tumor, and any successive tumors in the head and neck were analyzed. Results Second and successive tumors showed a tendency to appear more frequently in the oral cavity and oropharynx and had a lower stage than that of index tumors. Five-year survival rates after a first, second, third, and fourth tumors in the head and neck were 67.6%, 56.1%, 45.0%, and 32.1%, respectively. Conclusion Survival decreased progressively with every new head and neck tumor. © 2012 Wiley Periodicals, Inc. Head Neck, 2012 Copyright © 2012 Wiley Periodicals, Inc.
