Abstract
Forty-nine patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN) were treated with 3 cycles of induction chemotherapy prior to definitive local treatment (surgery and/or radiation therapy). Chemotherapy consisted of carboplatin 300 mg/m2 on day 1, fluorouracil 1000 mg/m2 daily as a continuous infusion on days 1 to 5 and high-dose methotrexate 1.2 g/m2 with leucovorin rescue on day 14. After completing the induction chemotherapy, 9 patients (18%) achieved a complete remission (CR), 26 (54 %) a partial remission (PR), 7 had stable disease and 7 a progression. The response rates increased to 53 % CR and 18 % PR following locoregional treatment. Survival at 12 months was 61 % and its actuarial probability at 24 months 31 %. Median time to progression was 14 months. Toxicity from chemotherapy was generally mild. Nausea was observed in 35 %, vomiting in 26 %, stomatitis in 57 %, anemia in 22 %, leukopenia in 36%, thrombocytopenia in 26% and diarrhea in 6% of the patients. In conclusion, the combination of carboplatin, 5-day continuous-infusion fluorouracil and mid-cycle high-dose methotrexate is a moderately effective, well tolerated regimen in patients with SCCHN but does not seem superior to the combination of carboplatin and fluorouracil only.
