Treatment of choice for XXXX of the tonsillar fossa.

@entity1 @entity135 @entity5 @entity957 @entity3
The records of 160 @entity1 with @entity957 of the tonsillar fossa treated from 1968 through 1979 were reviewed. Biologic behavior, local and regional findings, and other prognostic factors were evaluated. @entity1 were treated by either radiation alone (112 @entity1 ), radiation followed by planned neck dissection (31 @entity1 ), surgery alone (11 @entity1 ), or surgery combined with radiation (6 @entity1 ). Analysis of the data supports the recommendation that radiation be used as treatment for T1, T2, and early T3 lesions, whereas surgery alone or combined with radiation is best employed for advanced T3 or T4 @entity5 . @entity5 control rates with radiation as the initial modality were 100% for T1 lesions, 89% for T2, 68% for T3, and 24% for T4. In addition, the control of cervical @entity3 with radiation therapy for @entity1 with @entity135 staged N0 through N3b was excellent (95%). In instances where a planned neck dissection was done 5 weeks after radiation, the control of @entity5 in the neck was 100%. The incidence of distant @entity3 was 10% and was not affected by the selection of therapy. The 2- and 5-year determinate survival figures for 112 @entity1 treated with radiation therapy alone was 67% and 48% respectively, while 31 @entity1 treated with radiation therapy followed by neck dissection achieved survival rates of 70% (2 year) and 58% (5 year). The criteria for selection of treatment are discussed.
