Cisplatin (Platinol)-based chemotherapy has been the standard systemic therapy for both non-small-cell and small-cell lung cancer for the past 2 decades, though the efficacy and benefit remain modest. Recently, several novel agents have been introduced that have single-agent activity comparable to cisplatin and offer the possibility of improved therapy for lung cancer. Camptothecin and taxane derivatives are associated with both different mechanisms of action and nonhematologic toxicities, and have demonstrated additive or synergistic activity when used in combination in preclinical studies. We review pertinent clinical studies of these agents in lung cancer and present our experience in combining irinotecan (Camptosar, CPT-11) with taxanes on a weekly schedule in dose-finding and efficacy studies. When chemotherapy is delivered for 4 consecutive weeks followed by a 2-week rest, hematologic toxicity is dose limiting and most prominent during weeks 3 and 4. Dose intensification is feasible if the schedule is modified so the chemotherapy is given on days 1 and 8, with cycles repeated every 3 weeks. The most common nonhematologic toxicities remain asthenia, neuropathy, and diarrhea. Future studies will explore and better define the role of these drug combinations in the treatment of lung cancer.
