Brief Summary
Previously, preliminary results, from a subgroup analysis of STARS-RC03 (NCT04906044) conducted by our research team, showed that the 6-cycles consolidation chemotherapy combining with anti-PD-1 thera...
Detailed Description
The combination of total neoadjuvant treatment (TNT) and immunotherapy has shown a significant improvement in the pCR rate compared to the standard of care (SOC) or TNT alone for pMMR LARC. On this ba...
