title: Neo-adjuvant chemotherapy +/- immunotherapy with s.c. IL 2 in advanced squamous cell carcinoma of the head and neck: a pilot study.
abstract: We carried out a pilot nonrandomized phase II study to compare the neo-adjuvant chemotherapic regimen with cisplatin, 5-FU and vinorelbine with the same combination plus s.c. IL 2 in advanced head and neck squamous cell carcinoma (HNSCC). The primary goals of the trial were to evaluate the feasibility and response rates of the two regimens. The study design consisted of a patient's assignment to either of the two following arms: Arm A: Cisplatin 80 mg/m2 i.v. on day 1; 5-FU 600 mg/m2 i.v. on days 2-5; and vinorelbine 20 mg/m2 i.v. on days 2 and 8, Arm B: the same chemotherapic regimen plus recombinant IL 2 (Proleukin, Eurocetus) 9 MIU s.c. daily from day 9 to 13 and from day 16 to 20 for every cycle. From March 1993 to November 1993 twenty three patients with Stage III-IV HNSCC were enrolled in the study. Patients could be evaluated for response to treatment if they had received at least 2 complete cycles of therapy. The overall response rate (ORR) was 63% in Arm A and 100% in Arm B. The differences for ORR and CR rates were statistically significant in favor of Arm B. The analysis for each of the three drugs included in the chemotherapy schedule shows that both the actually received average dose-intensity and the actually delivered average cumulative doses/patient were higher for Arm B (chemo-plus IL 2 therapy) (approximately 80% of programmed dose-intensity) than for Arm A (approximately 70% of programmed dose-intensity). Both the actually received average dose-intensity and the actually delivered average cumulative doses/patient for IL 2 were more than 80%. In both arms the most frequent side effects were myelosuppression, phlebitis and electrolyte disturbances. There were 2 toxic deaths, 1 in Arm A and 1 in Arm B, both for hematologic toxicity. Our "pilot" study suggests that the combination of cisplatin, 5-FU, vinorelbine plus IL 2 is a highly active, but rather toxic, neo-adjuvant treatment in advanced HNSCC with very high ORR and CR rates.
