An intensive, five course, alternating combination chemotherapy induction regimen used in patients with advanced, unresectable head and neck cancer.
Progress in the treatment of advanced squamous cell cancer (SCC) of the head and neck (H & N) has included the development of combination chemotherapeutic regimens that achieve impressive complete response (CR) rates using two to three courses therapy with minimal toxicity and good patient tolerance. Further improvements in these results will require intensification of induction regimens. Therefore, a five course, alternating combination chemotherapy induction trial was initiated in an attempt to test the feasibility and toxicity of a prolonged, intensive induction regimen in patients with advanced SCC of H & N. Courses 1, 3, and 5 consisted of fluorouracil as a 120-hour infusion (5FU-I) with cisplatin (CACP) as an intravenous (IV) bolus. Courses 2 and 4 consisted of 3 weekly doses of high-dose methotrexate (HDMTX) followed by 5FU (5FU-b) and leucovorin rescue (LR). Forty-six stage IV patients with SCC of H & N (85% T4 and 58% N3) were entered. Thirty-one patients completed the study and 15 did not. Twenty-one of the 46 patients (46%) achieved a CR. Twenty-five of the 46 patients had N3 neck disease, ten of these 25 achieved a CR (40%), and eight did not complete therapy. Of the 15 patients not completing this study, one patient achieved a CR and eight achieved a partial response (PR). Eight of 46 (17%) were removed from study for reasons of toxicity (6% to 13%) or tumor progression (2% to 4%). The remaining seven were removed due to intercurrent medical conditions (four uncomplicated pneumonias and one gun shot wound) or lost to follow-up (2). Myelosuppression, mucositis, and skin toxicity increased in frequency by the end of the trial but were acceptable and reversible. The activity of this five-course regimen is promising given the advanced disease status of patients treated. Consideration of concurrent medical conditions, patient compliance, intensity of medical, nutritional and social support, and levels of acceptable toxicity will be necessary in the design of future, intensive induction trials.
