Preliminary Study of Chemoradiotherapy Using Modified Docetaxel, Cis‐diaminodichloroplatinum, and 5‐Fluorouracil for Sinonasal Squamous Cell Carcinoma

Abstract

Objective To examine the safety and efficacy of concomitant chemoradiotherapy using a modified TPF regimen (docetaxel + cisplatin + 5-fluorouracil) in patients with advanced sinonasal squamous cell carcinoma (SNSCC). Study Design Retrospective study. Setting Tertiary center (university hospital). Methods Seven patients with previously untreated T3-T4 SNSCC were enrolled. They underwent radiotherapy once daily (total dose, 70 Gy) with 2 courses of concomitant 120-hour infusion of 5-fluorouracil (600 mg/m2/d), docetaxel (50 mg/m2, day 2), and cisplatin (60 mg/m2, day 2) Results Grade 4 leukopenia, grade 4 neutropenia, and grade 3 lymphopenia were observed in 1, 3, and 4 patients, respectively. Grade 4 creatinine elevation was observed in 1 patient. However, other grade 3 or 4 adverse events were not common. Complete response was obtained in all patients. At 60 months there was 85.7% disease-free survival and 100% overall. Conclusion Concomitant chemoradiotherapy with a modified TPF regimen may be feasible and effective in patients with advanced SNSCC.
