Classical and XXXX : difference in survival.

@entity1 @entity5 @entity34 @entity4797
Classical and @entity4797 are traditionally treated with radiation therapy and are said to have the same prognosis. A retrospective study was undertaken of 90 @entity4797 @entity1 treated with radiation therapy between 1961 and 1985. The classical group consisted of 71 @entity1 of whom 50 had stage I and 21 had @entity34 . The anaplastic group consisted of 19 @entity1 of whom ten had stage I and nine had @entity34 . The median follow-up time was 64 months for the entire group. The 10-year relapse-free survival rate for the classical group was 94% and for the anaplastic group was 70% (P less than .05). For @entity1 with classical stage I disease, the relapse-free actuarial survival rate was 98%; for @entity1 with anaplastic stage I disease, it was 64% (P less than .02). For the classical @entity34 group, the relapse-free actuarial survival rate was 84% and for the anaplastic @entity34 group, 75% (P less than .70). Four @entity1 in the classical group (6%) had relapses; of these, one @entity1 had local recurrence of @entity5 , and three had distant metastases. In the anaplastic group, four @entity1 (21%) had relapses; two @entity1 had local recurrence of @entity5 , and two had distant metastases. Therefore the data suggest a difference in survival and relapse rates between classical and @entity4797 .
