Aim: To assess the impact of a two-step multiparameter selection on the actual enrollment of women with breast cancer into a prospective intraoperative radiotherapy (IORT) trial. PATIENTS AND METHODS: From September 2009, a prospective clinical trial was started in order to deliver adjuvant exclusive single -fraction IORT to patients with early breast cancer. To select patients meeting suitable eligibility criteria for the clinical trial, a two-step decision process was developed: at pre-surgical examination (first step) and during surgery (second step). RESULTS: A series of 464 patients with breast cancer was analysed: at the first step, out of 464 patients, 333 (71%) were considered eligible for the IORT protocol; at the second step, out of 333 patients, 199 (60%) met the eligibility criteria and received the IORT fraction according to the criteria of the controlled trial. CONCLUSION: In our experience, the ultimate rate of patients who enrolled in the IORT clinical trial after the two-step decision process was 43%. PMID:22493397[PubMed - in process]

Abstract
Aim: To assess the impact of a two-step multiparameter selection on the actual enrollment of women with breast cancer into a prospective intraoperative radiotherapy (IORT) trial. PATIENTS AND METHODS: From September 2009, a prospective clinical trial was started in order to deliver adjuvant exclusive single -fraction IORT to patients with early breast cancer. To select patients meeting suitable eligibility criteria for the clinical trial, a two-step decision process was developed: at pre-surgical examination (first step) and during surgery (second step). RESULTS: A series of 464 patients with breast cancer was analysed: at the first step, out of 464 patients, 333 (71%) were considered eligible for the IORT protocol; at the second step, out of 333 patients, 199 (60%) met the eligibility criteria and received the IORT fraction according to the criteria of the controlled trial. CONCLUSION: In our experience, the ultimate rate of patients who enrolled in the IORT clinical trial after the two-step decision process was 43%. PMID:22493397[PubMed - in process]
