The role of adjuvant irradiation in the treatment of transitional cell @entity703 was reviewed. Between June 1966 and March 1981, 41 @entity1 underwent curative resections. A poor risk group was identified, with 23 @entity1 demonstrating disease greater than grade 2 or stage B. Postoperative irradiation was administered to 11 of 23 @entity1 . Median @entity1 followup was 40 months. Two-thirds of all failures occurred within the first 12 months and no failure was seen beyond 35 months. @entity1 with poor prognostic features had a 60 per cent failure rate compared to 11.8 per cent of the @entity1 with good risk factors (p equals 0.023). The median survival of the 2 groups was 28 and 99 months, respectively (p less than 0.001). Outcome of the poor risk @entity1 was analyzed whether or not the @entity1 received postoperative irradiation. None of the irradiated @entity1 failed with @entity66 only, while there was 1 @entity1 with local and distant recurrence. In contrast, the nonirradiated group had 5 local failures and twice the number of failures over-all. Median survival of the irradiated and nonirradiated @entity1 was 35 and 26 months, respectively. The number of @entity1 treated is too small to permit valid statistical conclusions and indicates the need for a multi-institutional study to determine if these suggestive findings of improved local control will be corroborated and translate into an improved survival rate.
