[Results of radiotherapy in the treatment of 218 XXXX of the tonsillar area].

@entity1 @entity3329 @entity5 @entity189 @entity204 @entity9212
After a brief review of the literature, the results of the treatment by radiation therapy in 218 @entity1 with tonsillar region @entity189 are reported. The @entity1 were treated at the Turin University Radiotherapy Department (131 cases) and at the Radiotherapy Department of the Ospedale Maggiore, Novara (87 cases) from 1976 through 1984. The series included 29 T1, 88 T2, 64 T3 and 37 T4; 86 @entity1 (40%) were N0. Only 49 @entity1 were stages I and II (1/4 of the total). The local control (T) rate at the end of therapy was 63.5% for the overall series (139/218) ranging from 100% in T1, 72.6% T2, 54.6% T3 to 30% T4; the regional control (N) for @entity1 with cervical @entity3329 was 66% (88/132). The overall 5-year survival was 38%; the 5-year disease-free survival was 35%. The 5-year survival according to T-stage was 52% for limited cases ( @entity9212 ) in comparison to 22% for advanced ones (T3-T4). The 5-year survival for N0 stage was 55%; when neck nodes were present (N # 0) the survival was 29% after 5 years. Complications included 6 cases of trismus and 2 osteonecroses of the mandible. Second primary @entity5 were seen in 17 cases (7.8%). The most common cause of @entity204 was failure in primary @entity5 control (80% of cases). In this series the results of radiotherapy of @entity5 are quite good; @entity1 with large @entity5 masses fare less satisfactorily. Better results should be obtained in the future by identifying prognostic factors, monitoring potential causes of treatment failure and optimizing the radiotherapeutic treatment plan and technique.
