RESUMO
To determinate MTD, DLT and safe doses for phase II study, a dose finding study with Mitomycin and Adriamycin Stop-Flow administration was carried out. A phase II study focused on resectability of pelvic colorectal relapses is in progress. From November 1995, 84 pts, 52 male and 32 female (94 treatments), with advanced not resectable abdominal (14 pts) or pelvic (70 pts) relapses, and resistant to previous systemic chemotherapy, were enrolled in the study. 46 pts entered the phase I-early phase II study, while subsequently 38 pts were recruited in ongoing phase II study. Safe dose were: MMC 20 mg/mq and ADM 75 mg/mq. The phase II study focused on colorectal relapses registered very promising responses: 90% pain control, 1 pCR and 26 PR / 63 (OR 43%), 8 NC (13%) 9/27 responder patients (33%) obtained a complete resectability of colorectal relapses. Stop-Flow is a safe and feasible technique very useful as a palliation treatment.
