RESUMO
BACKGROUND: A phase II study was carried out to investigate an induction regimen with cisplatin, paclitaxel followed by radiotherapy concurrent with weekly cisplatin for locally advanced squamous cell carcinoma of the head and neck. PATIENTS AND METHODS: Stage III-IV disease patients were eligible. Two cisplatin (100 mg/m2) and paclitaxel (175 mg/m2) courses were administered every 21 days followed by standard fractionated external beam radiotherapy (approximately 70 Gy), concomitant to weekly cisplatin (30 mg/m2). RESULTS: Thirty-five patients were enrolled: over 70% had unresectable disease with bulky lesions. Grade 3-4 neutropenia developed in 14% and G3 mucositis in 23%. Locoregional control was achieved in 51%. Median time to progression and overall survival were 10,7 and 17 months respectively; 2- and 3-year survival rates were 30% and 25% respectively. CONCLUSION: Our induction two-drug regimen followed by chemoradiotherapy with concurrent weekly cisplatin was well tolerated with low acute toxicity and good locoregional control and survival rate.

BACKGROUND: Cisplatin, paclitaxel and 5-fluorouracil (5-FU) have demonstrated significant activity in patients with advanced squamous head and neck cancer (HNSCC) despite relevant toxicity. A weekly administration of cisplatin and paclitaxel with continuous infusion of 5-FU could offer a better toxicity profile without affecting dose intensity or treatment outcome. We evaluated the toxicity and the activity of weekly cisplatin/paclitaxel with continuous infusion 5-FU in patients with recurrent and/or metastatic HNSCC. METHODS: A total of 44 patients were studied. Treatment consisted of two 6-week cycles with weekly cisplatin 20 mg/m2 and paclitaxel 60 mg/m2 and daily continuous infusion 5-FU 200 mg/m2 from day 1 to 42. Patients were evaluated for toxicity and response. RESULTS: 40 out of 44 patients were evaluable for response. After two cycles we observed seven complete responses (16%) and 12 partial responses (27%), with a 43% (95% CI 28-58%) overall response rate. Stable disease was seen in 13 patients (29%) and progressive disease in 12 patients (27%). Toxicity was mild in treated patients: we observed less than 10% of grade 3/4 hematological and gastroenteric toxicity. CONCLUSIONS: A weekly schedule of cisplatin and paclitaxel associated with continuous infusion 5-FU showed low toxicity in the treatment of advanced HNSCC while significant activity was conserved.
