- Meeting Minutes January 2005 - "Dr. Brad Prestidge updated the group on RTOG 0232. This randomized trial has had slow accrual to date. The projected monthly accrual was 25.3 cases per month and the average monthly accrual for the past six months was 6.8 cases per month. We discussed the possibility the credentialing process is an obstacle to registering patients on a trial. It was pointed out the number of institutions credentialed exceeds 50 and the RPC and ITC were working on methods to reduce the burden of the credentialing process. In addition, two more treatment-planning systems are now able to allow institutions to participate in a clinical trial (Rosses and RTek). There was a brief discussion about hormone therapy being allowed on the protocol and as it stands up to two months of hormone therapy is allowed prior to registration. Patients may receive six months of hormone therapy. Finally, it was agreed IMRT be allowed on this trial. For the purpose of this study central Quality Assurance of the IMRT is not allowed. Institutions have the option of either being credentialed using IMRT for any of the RTOG studies using the RPC Phantom or using the QARC Benchmark tool."
- Meeting Minutes June 2004 - "Dr. Prestige announced accrual remains slow on RTOG 0232 – the randomized study for brachytherapy plus external beam radiation therapy versus brachytherapy alone for early stage prostate cancer. He encouraged institutions to get credentialed for electronic data submission of permanent brachytherapy treatment plans. Dr. Michalski pointed out there was some interest from institutions in the UK to participate."
