title: Carboplatin in the Treatment of Small Cell Lung Cancer.
abstract: Small cell lung cancer (SCLC) will account for approximately 20%-25% of the 171,500 estimated new lung cancer cases in 1998. Combination cytotoxic therapies have yielded the best response rates in SCLC patients. Cisplatin in combination with etoposide is used routinely in the treatment of SCLC. Because of cisplatin's nonhematologic toxicities, carboplatin was developed and has far fewer nonhematologic toxicities. Carboplatin in combination with etoposide has been shown to be as effective as, but less toxic than, cisplatin/etoposide. Moreover, carboplatin/etoposide is a viable combination in the treatment of the elderly with SCLC, who can readily tolerate this combination. Concurrent radiation therapy with carboplatin and etoposide in patients with limited SCLC disease can be given safely and effectively. Carboplatin has been combined with several different chemotherapeutic agents, including ifosfamide, and, more recently, paclitaxel in hopes of improving the response rates and overall survival. In order to try to dose intensify carboplatin-based regimens, peripheral blood stem cells have been used to decrease the hematologic toxicities. Further studies are warranted to investigate these therapies as well as newer carboplatin combinations.
