Background. Patients with advanced, inoperable head and neck cancers have cure rates of approximately 10-15%. In these patients, concomitant chemoradiotherapy seems to improve local control and survival. 5-Fluorouracil (5-FU) administered by continuous infusion and cisplatin plus concomitant conventional radiation therapy may be promising in treating advanced, inoperable head and neck cancers. Methods. Forty-five evaluable patients with primary nonmetastatic, inoperable head and neck cancers were treated. From January 1987 to April 1988, the patients were treated with cisplatin plus radiation therapy (Group 1) and from May 1988 to November 1990, they were treated with the same combination plus 5-FU, given in continuous infusion (Group 2). Clinical and pathologic responses were assessed after radiation therapy was completed. Patients who relapsed underwent salvage surgery, if possible. The disease free and overall survival rates of the patients were evaluated. Results. The overall response rate (complete and partial response) was 93%, 60% of which comprised complete remissions. Despite the high response rates obtained in the two groups, the time to progression for complete responses and the median survival time were unsatisfactory (13 [Group 1] and 10 months [Group 2] and 17 [Group 1] and 16 months [Group 2], respectively). The toxicity rate from the two treatments was not relevant. A Grade II mucositis, according to the World Health Organization, was found in 25 patients, and the treatment was interrupted for 7-10 days in 5. Conclusions. In this study, despite an improvement in the number of complete responses, the chemotherapeutic regimen with or without 5-FU did not prolong the overall patient survival significantly.

Thirty pretreated patients with progressive and measurable solid tumors (24/30 patients) or myeloproliferative diseases (6/30 patients) were given mitoxantrone at the dose of 5 mg/m2/day in 250 ml normal saline over 30 minutes infusion for 3 consecutive days every 3 weeks. A total of 104 cycles were administered, median 3 for each patient. 39/104 cycles were delayed for a median of 9 days (from 2 to 59 days) because of myelodepression grade I to III (median I); no infection or bleeding was observed. Grade I to II alopecia was recorded in 16 patients. Chronic cardiac toxicity was observed in one patient previously treated with adriamycin. Mitoxantrone at the studied dose schedule in heavily pretreated subjects was well tolerated every 3 to 4 weeks. In 25/30 patients evaluable for response, one patient had a PR, another had 25% reduction (both patients previously treated) and eleven patients obtained disease stability. This effectiveness, 1 PR, 1 MR, 11 disease stability, is not negligible when it is considered that mitoxantrone was the seventh median line of therapy and the fifth median antiblastic drug.
