Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The question of how to administer adequate chemotherapy and immunotherapy to synchronise hypofraction radiotherapy (HFRT) treatment strategy to maximise the benefits of neoadjuvant therapy for the improved prognosis of patients with locally advanced rectal cancer (LARC).We aimed to study whether chemotherapy and tislelizumab plus split-course HFRT results in better outcomes in LARC patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Prior to analyzing continuous variables, the statistical normality of the data will be determined. The differences between the main variables will be compared by using the analysis of variance. A comparison of data on categorical variables will be carried out by χ2 tests or Fisher's exact tests. The OS and PFS was estimated using the Kaplan-Meier method. PFS and OS will be compared using the log-rank test. In cases where variables must be adjusted, we will use the proportional hazard Cox regression model. P values for all analyses will be based on using a significance level of 0.05.
