Resumen
Fecha de inicio: 1 de junio de 1996
Fecha en la que se inscribió al primer participante.Subjects were stratified according to pO2 values (high vs low), and randomized to 1 of 2 treatment arms, differing by the addition of tirapazamine to the therapeutic regimen. Treatment consists of two 21-day cycles of induction chemotherapy, followed by radiotherapy (RT). Induction chemotherapy was cisplatin 100 mg/m2 per day administered over 4 hours on Study Days 1 and 22 (ie, 1st day of both induction cycles) with continuous infusion (CI) 5-FU at a dose of 1000 mg/m2 per day for 120 hours per cycle starting on Study Days 1 and 22 (ie, days 1 to 5 of both induction cycles). Patients who achieve at least partial response proceeded to chemoradiotherapy (CRT) consisting of localized RT + cisplatin IV + 5-FU +/- tirapazamine. Location of RT was based on whether the site had a CR or PR. Radiotherapy began on day 43 (week 1), and continued for 5.5 weeks. Subjects with no response or progressive disease proceeded to salvage surgery. A total of 63 patients were accrued for this study over approximately 5 years. 1 subject withdrew consent prior to treatment for personal reasons.
