Camrelizumab is a humanized PD-1 monoclonal antibody. Camrelizumab combined with the antiangiogenic drug apatinib has achieved good efficacy in extensive small-cell lung cancer. Median OS is 8.4 months. In our study, subjects with extensive stage small cell lung cancers receive 2 cycles of chemotherapy followed by carrizumab combined with apatinib and chemotherapy. we hope to achieve a better outcome.
The efficacy of PD-1/PD-L1 combined with chemotherapy in the treatment of extensive small-cell lung cancer is still unsatisfactory. PD-1/PD-L1 combined with chemotherapy and anti-angiogenic drugs may achieve better efficacy.
