Abstract
BACKGROUND The goal of the current study was to evaluate the efficacy and toxicity of paclitaxel, cisplatin (P), tegafur (T), and leucovorin (L) as a neoadjuvant chemotherapy (CT) for patients with advanced, unresectable squamous cell carcinoma of the head and neck. METHODS From November 1999 to January 2001, 21 consecutive patients (Stage IV, 100%; T4, 86%; and N3, 41%) were treated with paclitaxel-PTL (Day 1: paclitaxel, 120 mg/m2 intravenous infusion for 3 hours; Day 1: P, 50 mg/m2; T, 800 mg; and L, 60 mg orally daily over a 14-day cycle). Evaluation after three cycles led to CT termination if primary tumor responses were less than partial responses. Otherwise, paclitaxel-PTL was continued for up to six cycles before commencement of locoregional therapy. RESULTS CT responses were analyzed on an intent-to-treat basis. Response rates (RR) for the primary tumors were 81% (17 of 21), with 28.6% (6 of 21) showing a complete response (CR). RR and CR rates for the neck lymph nodes were 85.3% (15 of 18) and 22% (4 of 18), respectively. The combined RR for primary tumors and neck lymph nodes was 81% (95% confidence interval, 62.9–99.3%) with a CR rate of 19%. Grade 3/4 toxicities according to World Health Organization criteria included leukopenia, 19.0%; emesis, 9.5%; asthenia, 9.5%; mucositis, 4.8%; and neuropathy, 4.8%. Both the overall and disease-free survival rates were 14.3% (3 of 21), with a median follow-up of 41 months. CONCLUSIONS The relatively low toxicities and encouraging response rates demonstrated in the current study suggested that paclitaxel-PTL merits future trials in the setting of resectable tumors with more favorable characteristics.
