Popis: Purpose: We conducted a Phase II, clinical trial to evaluate the efficacy and safety of a biweekly gemcitabine and paclitaxel (GEMTAX) regimen as second-line treatment in patients with recurrent or metastatic unresectable, squamous cell carcinoma of the head and neck (SCCHN). The primary endpoint was response rate. Patients and Methods: Patients with recurrent unresectable or metastatic platinum refractory SCCHN, who had performance status ≤2 and adequate organ function, were eligible. Gemcitabine (3000 mg/m 2 intravenous) and paclitaxel (150 mg/m 2 intravenous) was given on days 1 and 15of 4 weeks cycle, until patients had disease progression or unacceptable toxicity. Results: Disease control (partial response [PR] + complete response [CR] + stable disease [SD]) was noted in 19 patients (54%) and overall response (CR + PR) was noted in 8 patients (23%). However, the most frequent response outcomes were progressive disease in 16 patients (46%) and SD in 11 patients (31%). The most frequent Grade 3-4 adverse events were lymphopenia in 38 patients (75%), anemia in 20 patients (39%), and infection in 16 patients (31%). Median progression-free survival was 3.6 months; median overall survival was 6.3 months. Conclusion: The biweekly GEMTAX regimen has statistically significant grade 3 and 4 adverse events and has meaningful clinical activity as a second-line treatment in patients with recurrent or metastatic SCCHN who have received prior chemotherapy. This regimen may particularly be a useful treatment option in patients who progressed in
