The purpose of this study was to determine the efficacy and safety of a maintenance immunotherapy regimen administered to patients with recurrent/metastatic squamous cell carcinoma of the head and neck (RMHN) who showed clinical benefit from docetaxel, ifosfamide, and cisplatin chemotherapy (DIP). Every 4 weeks, patients with RMHN received 60 mg/m(2) docetaxel on day 1, and 1200mg/m(2) ifosfamide and 20mg/m(2) cisplatin on days 1 to 4. Low-dose subcutaneous interleukin-2 and oral 13-cis-retinoic acid were administered as maintenance immunotherapy to patients who showed a clinical benefit (complete or partial response, disease stability). The primary end point was response; secondary end points were progression-free survival, overall survival, toxicity, and evaluations of lymphocytes, natural killer cells, and serum vascular endothelial growth factor (VEGF). After a median follow-up of 22 months, 263 courses of chemotherapy were administered to the 54 patients. The overall response rate was 59%. Forty-two patients (78%) had a clinical benefit and received 185 courses of maintenance immunotherapy. Median progression-free survival and overall survival were 11.1 and 21.8 months, respectively. Statistically significant, progressive increases in lymphocytes and natural killer cells and a decrease in VEGF were observed in patients treated with maintenance immunotherapy. The toxicity was relatively well tolerated and caused no death. Outpatient administration of DIP, followed by low-dose interleukin-2 and 13-cis-retinoic acid, was generally well tolerated and showed promising activity against RMHN. Longitudinal changes in lymphocytes, natural killer cells, and VEGF might be useful biomarkers for response and survival.

Abstract

The purpose of this study was to determine the efficacy and safety of a maintenance immunotherapy regimen administered to patients with recurrent/metastatic squamous cell carcinoma of the head and neck (RMHN) who showed clinical benefit from docetaxel, ifosfamide, and cisplatin chemotherapy (DIP). Every 4 weeks, patients with RMHN received 60 mg/m(2) docetaxel on day 1, and 1200mg/m(2) ifosfamide and 20mg/m(2) cisplatin on days 1 to 4. Low-dose subcutaneous interleukin-2 and oral 13-cis-retinoic acid were administered as maintenance immunotherapy to patients who showed a clinical benefit (complete or partial response, disease stability). The primary end point was response; secondary end points were progression-free survival, overall survival, toxicity, and evaluations of lymphocytes, natural killer cells, and serum vascular endothelial growth factor (VEGF). After a median follow-up of 22 months, 263 courses of chemotherapy were administered to the 54 patients. The overall response rate was 59%. Forty-two patients (78%) had a clinical benefit and received 185 courses of maintenance immunotherapy. Median progression-free survival and overall survival were 11.1 and 21.8 months, respectively. Statistically significant, progressive increases in lymphocytes and natural killer cells and a decrease in VEGF were observed in patients treated with maintenance immunotherapy. The toxicity was relatively well tolerated and caused no death. Outpatient administration of DIP, followed by low-dose interleukin-2 and 13-cis-retinoic acid, was generally well tolerated and showed promising activity against RMHN. Longitudinal changes in lymphocytes, natural killer cells, and VEGF might be useful biomarkers for response and survival.
