efficacy and safety of anlotinib as maintenance treatment after first-line chemotherapy in sclc

Conditions: Carcinoma; Lung Neoplasm; Small Cell Lung Cancer

Summary: investigations prospectively collected the sclc patients who received current standard first-line treatment, the response was not progression disease(pd). and then participants receive anlotinib 12mg, administered as po on day1-14 of each 21-day cycle until documented pd or had unacceptable toxicity. this regimen is compared to the effects a observation without treatment after the first-line therapy. the aim of the study is therefore to evaluate the efficacy and safety of anlotinib as maintenance treatment after first-line chemotherapy in sclc patients.
