Explorative study, which evaluates the effect of Camrelizumab combined with albumin-bound paclitaxel and platinum in neoadjuvant treatment of resectable non-small-cell lung carcinoma.

This is a multicenter, randomized, open parallel controlled trial to evaluate the efficacy and safety of camrelizumab combined with albumin-bound paclitaxel and platinum versus albumin-bound paclitaxel combined with platinum in resectable stage IIIA -IIIB NSCLC (IIIB is limited toT3N2).
