Abstract

The efficacy of non-small cell lung cancer (NSCLC) has been obviously improved recent years, while the survival of small cell lung cancer (SCLC) patients remains inferior for limit treatment options. The incidence of SCLC accounts for 15% of the overall incidence of lung cancer, and it is characterized with high malignancy, rapid growth, early widespread metastasis, making it very difficult to treat. With the approval of immunotherapy for a variety of solid tumors including NSCLC, as a relatively immunogenic cancer species, relevant clinical researchs on SCLC are also underway and have made certain progress. More importantly, due to the existence of tumor heterogeneity, exploring relevant markers that can predict the efficacy of SCLC is essential for accurate therapy. This review describes the latest advances in SCLC immunotherapy and biomarkers related to the efficacy of immunotherapy.
