We reported three cases of stageⅢ/N2 non-small cell lung cancer (NSCLC) treated with neoadjuvant immunotherapy and stereotactic body radiation therapy (SBRT) in our hospital, including 2 males and 1 female with a mean age of 65.7 years. The patients received two doses of the programmed cell death protein-1 inhibitor toripalimab after 1 week of SBRT. Thereafter, surgery was planned 4-6 weeks after the second dose. One patient achieved pathologic complete response, one achieved major pathologic response (MPR), and one did not achieve MPR with 20% residual tumor. There were few side effects of toripalimab combined with SBRT as a neoadjuvant treatment, and the treatment did not cause a delay of surgery.
