Purpose: The purpose of this study was to test interferon alfa (IFNalpha), 13-cis-retinoic acid (13cRA), and cisplatin biochemotherapy in advanced squamous cell carcinoma (SCC) of the skin. Patients and Methods: Patients with advanced skin SCC received IFNalpha (5 x 10(6) IU/m(2), subcutaneous injection, three times a week), 13cRA (1 mg/kg, orally, daily), and cisplatin (20 mg/m(2), intravenous injection, weekly) in a phase If trial. The growth inhibition, cell-cycle, and apoptosis activity of these agents was evaluated in two skin SCC cell lines (SRB1-m7 and SRB12-p9). Results: Thirty-nine patients were enrolled. All were assessable for survival, 35 for response and toxicity (median follow-up was 38 months). The overall and complete response rates were 34% and 17%, respectively, with median durations of 9 and 35.4 months, respectively. The response rate was higher in locally advanced (67%) than metastatic (17%) disease (P = .007). Median survival was 14.6 months. One-, 2-, and 5-year survival rate estimates were 58%, 32%, and 21%, respectively. Toxicity included generally mild to moderate fatigue and mucocutaneous dryness, moderate to severe neutropenia (38%), and neutropenic fever (61/6). There were no treatment-related deaths. In vitro growth inhibition and apoptosis effects of cisplatin were differential and inversely associated with those of retinoic acid and especially IFNalpha in two skin SCC lines. Conclusion: The rising incidence, morbidity, and mortality of advanced skin SCC are a major challenge for clinical oncologists. Combined 13cRA, IFNalpha, and cisplatin was clinically active in extensive locally advanced disease. Each agent had independent, non-cross-resistant biologic effects in vitro, which may account for the combination's clinical activity. (C) 2002 by American Society of Clinical Oncology.
