Brief Summary

This is an open-label, single arm Phase II study designed to observe and evaluate the efficacy and safety of sequential thoracic radiotherapy in the first-line treatment of extensive small cell lung cancer with chemotherapy combined with approved PD-1/PD-L1 inhibitors.

Detailed Description

This study a single arm prospective phase II study. All the enrolled patients will be patients with ES-SCLC who did not have PD after 4-6 cycle of platinum-based chemotherapy in combination with an PD-1/PD-L1 inhibitors. Then, those enrolled patients would be treated with thoracic radiotherapy concurrently with PD-1/PD-L1 maintenance therapy.
