Because SCLC is almost always associated with long-term tobacco smoking, abstinence from smoking and smoking cessation are crucial for primary prevention. Because symptoms are generally unspecific, the disease is often diagnosed late, with 70% of patients already in stage IIIb or IV at the time of diagnosis. Early detection of SCLC through screening is under investigation. Chemotherapy, generally a platinum-based combination, is the mainstay of therapy and is generally combined with radiation in the first-line treatment of tumours up to stage IIIb. Surgery has a place in the diagnosis and therapy of stage I SCLC, but plays no key role in advanced cancer. In patients who respond to first-line therapy, prophylactic cranial irradiation can prevent brain metastases and improve overall survival. Although the initial response to treatment is usually good, SCLC tends to relapse quickly. This makes second-line therapy quite important. Topotecan is the most studied and widely used agent in second-line therapy; however, newer agents, including biological therapies, are under study.
