Brief Summary
Managements for refractory proficient mismatch repair (pMMR) or microsatellite stable (MSS) metastatic colorectal cancer (mCRC) were still challenging and controversial. Our study sought to investigate the efficacy and safety of anti-PD-1 antibodies plus regorafenib in refractory pMMR/MSS mCRC between July 2019 and June 2021 at the Hunan Cancer Hospital.

Outcome Measures
Primary Outcomes (1)
Overall Survival (OS)

Interventions
The patients were treated orally with regorafenib (80 mg once daily for 21 days on/7 days off, over a 28-day cycle), combined with 1 of the 5 anti-PD-1 antibodies (i.e., nivolumab, pembrolizumab, camrelizumab, sintilimab, or toripalimab). The anti-PD-1 antibody was administered intravenously on day 1, and its recommended dosage was as follows: nivolumab: 240 mg, every 2 weeks; pembrolizumab, camrelizumab, and sintilimab: 200 mg every 3 weeks; and toripalimab: 240 mg every 3 weeks

You may qualify if:
- Has histologically confirmed unresectable adenocarcinoma of the colon or rectum (all other histological types are excluded).
- \. Have progressed from at least 2 lines of standard treatment,including fluoropyrimidines, irinotecan, oxaliplatin, with or without targeted drugs, like bevacizumab and cetuximab (only for RAS wild-type).
