The inclusion of gemcitabine into an alternating regimen seems to improve the results achievable with the original alternating program in stage IV patients. However, due to the high acute toxicity correlated, this intensive regimen should be managed by institutions well trained in multidisciplinary treatments.
The aim of this multicenter trial was to test the feasibility and the activity of a three-drug combination where paclitaxel is added to cisplatin and 5-fluorouracil. Patients with metastatic or relapsed SCC-HN unsuitable for further loco-regional radical treatment, not previously treated with chemotherapy, were eligible to receive paclitaxel 160 mg/m2 (3-hr infusion) day 1, CDDP 25 mg/m2/day and 5-FU 250 mg/m2/day bolus on days 1, 2, 3 every three weeks up to a maximum of five courses. Fourty-seven patients were enrolled by five Institutions in Italy. Main grade III-IV toxicities were: neutropenia (48%), thrombocytopenia (6%), anemia (4%), diarrhea (2%), mucositis (2%). Six patients had a complete response (13.3%) and eight a partial response (17.8%). Median progression free survival and overall survival are 4.1 and 7.9 months. One-year progression free survival and overall survival are 16% and 29%. This three-drug regimen has an excellent safety profile. The activity in the palliation of recurrent SCC-HN, however, does not appear to be improved in comparison with cisplatin and 5-fluorouracil or cisplatin and paclitaxel regimens. Recent studies indicate a more promising role of taxanes including triplets in the induction therapy of previously untreated patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
