AbstractSmall-cell lung cancer (SCLC) is a rapidly progressing tumor in which chemotherapy has a limited impact on survival. Unfortunately, little progress has been made in the medical management of SCLC during the last 30 years, which is best exemplified by the fact that standard first-line chemotherapy has remained platinum-based over time. On the other hand, improvements in survival have been obtained only with the introduction of innovative radiation strategies such as accelerated hyperfractionation to the thorax for limited-stage disease and prophylactic cranial irradiation for both limited- and extensive-stage disease. However, recent advances in the understanding of SCLC biology have renewed the interest in the clinical development of active drugs for SCLC. In this review, we address the most promising agents under clinical evaluation, discussing both novel chemotherapeutic agents and targeted agents. Particularly, amrubicin, a fully synthetic anthracycline, is a very active agent for SCLC, and ongoing Phase III trials are evaluating this agent either in the first-line setting of extensive-stage or relapsed disease. Among targeted agents, anti-angiogenic strategies and Bcl-2 inhibitors represent the most promising approaches, and they are being specifically tested in combination with and/or as maintenance therapy after first-line platinum-based chemotherapy.
