Phase II trial of cisplatin and gemcitabine in advanced squamous-cell carcinoma of the head and neck.

Background: To evaluate the toxicity profile and efficacy of cisplatin combined with gemcitabine in patients with irresectable locally recurrent or metastatic squamous cell carcinoma of the head and neck.
Patients and Methods: Gemcitabine was given at a dose of 800 mg/m2 on days 1, 8 and 15, plus cisplatin at a dose of 50 mg/m2 on days 1 and 8; every four weeks.
Results: Twenty-four patients with a median age of 59 years (range 42-74) were included. All patients were evaluable for toxicity and 22 patients were assessable for response. Eleven cases had advanced recurrent locoregional disease while 13 patients had metastatic disease. One CR (4.7%) and four PR (18%) were observed, for an overall response rate of 22.7% (95% CI: 8%-42%). The main toxicity was hematological: neutropenia grade 3-4 in 28% of the cycles and thrombocytopenia grade 3-4 in 16%. The most significant non-hematological toxicity was asthenia grade 2-3 in 24% of the cycles.
Conclusions: This cisplatin plus gemcitabine combination schedule has a favourable toxicity profile with a discrete activity in patients with locally recurrent or metastatic squamous-cell carcinoma of the head and neck.
