Gemcitabine/carboplatin combination regimens: importance of dose schedule.
Platinum compounds, either cisplatin (Platinol) or carboplatin (Paraplatin), in combination with a number of new chemotherapeutic agents, have demonstrated improved response or survival compared to cisplatin alone or older platinum-based regimens. Gemcitabine (Gemzar)-platinum combinations are of particular interest because of their interactive mechanisms of action, demonstrated preclinical synergism, and the single-agent activity of gemcitabine. Indeed, gemcitabine and cisplatin regimens have proven to be among the most efficacious in the palliative treatment of advanced non-small-cell lung cancer. In view of the reduced nonhematologic toxicities associated with the platinum analogue, carboplatin, several combinations of new agents and carboplatin have been developed and incorporated into clinical practice. This article describes recent clinical trials evaluating gemcitabine plus carboplatin, and the impact of the dosing schedule on the feasibility and tolerability of this combination.
