Filter by:SCLC constitutes approximately 15% of the 170,000 new cases of lung cancer diagnosed annually in the United States(1). Extensive-Stage SCLC comprises two thirds of new cases and is generally considered sensitive to chemotherapy, despite a median time to progression of 4 months(2). SCLC is one of the most aggressive and lethal types of cancer, with a median survival of 9 months (range 7-11 months) in patients diagnosed with extensive disease(3). Overall, the majority of patients with SCLC die in less than 2 years (2-year survival rates generally less than 10%), and the 5-year survival rate is 2.3% for patients with extensive disease(4). The regimen of etoposide in combination with a platinum (cisplatin or carboplatin) is generally considered the "standard of care" although a recent Phase III trial suggests improved survival with the combination of cisplatin/irinotecan(5). Further evaluation of new agents in combination regimens attempting to overcome the intrinsic drug resistance seen in extensive-stage SCLC is warranted attempting to improve survival and achieve palliation of disease-related symptoms.
