Brief summary (as posted)
This phase II multicenter, randomized study evaluates the safety and efficacy of neoadjuvant short-course radiotherapy (SCRT) sequentially combined with AK112 (Envafolimab) with or without chemotherapy in patients with locally advanced rectal cancer (LARC). The study also aims to identify biomarkers predicting tumor response and develop efficacy prediction models.
