Intravenous 5-Fluorouracil in Patients With Advanced Squamous Cell Carcinoma: A Retrospective Study:

Objectives:In the EXTREME trial, a combination of cisplatin or carboplatin plus 5-fluorouracil (5-FU) and cetuximab was superior to cisplatin/carboplatin plus 5-FU for first-line treatment of recurrent or metastatic head and neck squamous cell carcinoma (HNSCC). With the aim of improving fluoropyrimidine-related tolerance without decreasing its efficacy, the safety and efficacy of carboplatin plus the oral fluoropyrimidine tegafur and cetuximab were investigated.Methods:A retrospective analysis of 104 patients with recurrent or metastatic HNSCC was conducted. Patients were treated with carboplatin (area under the curve: 5 mg/mL/min) on day 1, oral tegafur (250 mg/m2 twice daily) for 21 consecutive days, and cetuximab (400 mg/m2 as an initial 2-hour intravenous infusion, then 250 mg/m2 as a 1-hour weekly infusion for 3 weeks) for ≤6 cycles. Patients who responded to the therapy then received weekly cetuximab maintenance therapy.Results:Treatment was well tolerated with a high level of compliance (relative ...
