Past, present, and future of gemcitabine and carboplatin regimens in advanced non-small cell lung cancer.
Several chemotherapeutic regimens have emerged in the past 5 years with the capability to improve survival and quality of life of patients with advanced non-small cell lung cancer (NSCLC). Among these treatments, the regimen of gemcitabine (Gemzar) and carboplatin (Paraplatin) has gained increasing acceptance. The combination of these two drugs was initially hampered by unacceptable platelet toxicity. However, the use of a 21-day schedule with the administration of gemcitabine on days 1 and 15 or the use of a 28-day schedule with the omission of day-15 gemcitabine has clearly been well tolerated and active. Unlike taxane based regimens, there is no need for steroid premedication, and neurotoxicity and alopecia are absent. This regimen is well tolerated and easily administered on an outpatient basis. It therefore represents an excellent "platform regimen" for the addition of new agents, particularly those associated with minimal myelotoxicity. Three-drug regimens consisting of gemcitabine/carboplatin and a taxane have been evaluated both with concurrent and sequential administration of the drugs. Trials are under way or planned for the addition of novel agents such as C225, UCN-01, PKC-alpha antisense, bexarotene, COX-2 inhibitors and other agents.
