Second line chemotherapy with methotrexate and gemcitabine in patients with relapsing head and neck cancer.

PURPOSE: The aim of this study was to evaluate the efficacy and toxicity profile of the combination of methotrexate and gemcitabine given as second-line treatment in patients with relapsing and/or metastatic head and neck cancer (HNC). PATIENTS AND METHODS: A total of 21 patients with HNC who had relapsed after first-line treatment with cisplatin-containing regimens were enrolles. Treatment consisted of intravenous (i.v.) administration of methotrexate 30 mg/m(2) and gemcitabine 800 mg/m(2) on days 1, 8, and 15 in cycles of 28 days. Primary sites included the larynx, tongue, nasopharynx, hypopharynx, nasal cavity, and parotid gland. The study end point was the evaluation of treatment efficacy and toxicity. RESULTS: Seven (33%) patients received only 1 or 2 cycles and discontinued treatment because of disease progression. Among 14 patients evaluable for respone, 1 complete (CR) and 2 partial responses (PR) were observed, yielding a response rate of 21.4%. The patient with CR remains relapse-free for 74(+) months. The 2 PR patients relapsed after 14 and 25 months and are still alive at 18 and 32 months, respectively. Seven patients showed minor response (MR) or stable disease (SD) with symptomatic relief lasting 4-12 months (mean 8). All but 2 of adequately treated patients (12/14 or 85.7%) attained a clinical benefit response (CBR). Mean time to progression (TTP) of all patients was 8 months (range 1-74(+)), while mean overall survival (OS) was 14 months (range 1-74(+)). Toxicity was mild to moderate and easily manageable. CONCLUSION: Methotrexate and gemcitabine combination is an effective second-line treatment for patients with relapsing and/or metastatic HNC. Moreover, this regimen is well tolerated with mild to moderate, easy to treat, toxicity.
