Canadian Cancer Trials Group Bulletins


Highlighted Trial -- Canadian Cancer Trials Group PR.2

Long-awaited results from Canadian Cancer Trials Group PR.2 (SWOG 8794) show that men who received radiation therapy within 12 weeks of surgery delayed a recurrence of the cancer, and this led to longer survival compared with men who did not receive the treatment. Results from this randomized 425-person trial appeared in the March Journal of Urology.

The recent edition of the NCI Bulletin is highlighting these results as a Special Report. It suggests, however, that these results raise the question of when is the optimal time to give the radiation? And, while it is unlikely that a single trial could answer this question, clues could come from the Canadian Cancer Trials Group PR.13 (MRC PR.10) trial -- RADICALS: Radiotherapy and Androgen Deprivation In Combination After Local Surgery.
