ABSTRACT
Treatment for small-cell lung cancer (SCLC) has changed little over the past few decades; available therapies have failed to extend survival in advanced disease. In recent years, immunotherapy with treatments such as interferons, TNFs, vaccines and immune checkpoint inhibitors has advanced and shown promise in the treatment of several tumor types. Immune checkpoint inhibitors such as ipilimumab, nivolumab, pembrolizumab, durvalumab, tremelimumab and ulocuplumab are at the forefront of immunotherapy and have achieved approvals for certain cancer types, including melanoma (ipilimumab, nivolumab and pembrolizumab), non-SCLC (nivolumab and pembrolizumab) and renal cell carcinoma (nivolumab). Clinical trials are investigating different immunotherapies in patients with other solid and hematologic malignancies, including SCLC. We review emerging evidence supporting the use of immunotherapy in SCLC patients.
