Summary

This study aims to elucidate the regression effects of neoadjuvant chemotherapy combined with immunotherapy and adjuvant therapy in locally advanced MSS colon cancer.

Conditions

  • Colon Neoplasm

Interventions

DRUG

Oxaliplatin

Oxaliplatin 130mg/m2 for inducing chemotherapy on Day 1 every 3 weeks and repeat for 4 cycles. The dose reduction protocol for oxaliplatin-induced toxicity was implemented according to the report in BJC (2018) 118:1322-1328.

DRUG

Capecitabine

Oral Capecitabine 1000 mg/m2 twice daily combined with oxaliplatin chemotherapy from Day 1 to Day 14 every 3 weeks and repeat for 4 cycles. The dose reduction protocol for capecitabine-induced toxicity was implemented according to the report in BJC (2018) 118:1322-1328.

DRUG

Anti-PD-L1 Monoclonal Antibody

The incidence of adverse events with Anti-PD-L1 Monoclonal Antibodies is relatively low. Based on phase I clinical trial data of Envafolimab, a dose reduction design was conducted to minimize the incidence of adverse events while ensuring therapeutic efficacy. In the two cohorts of the efficacy-enhancing design, a reduced dose of 100mg/0.5ml IH QW will be used for 6 weeks. The PD-L1 monoclonal antibody (Envafolimab) dose adjustment was implemented according to the prescribing information.

DRUG

Clostridium butyricum

Clostridium butyricum is treated with Miyarisan 588 powder, 160mg/day (4 packets/day) taken orally for a total of 6 weeks.There have been no reports of adverse reactions for Lactobacillus. There is no predetermined reduction plan.

PROCEDURE

Colectomy

The specific surgical approach, whether it be laparoscopic or open surgery, is determined by the surgeon. The tumor blood supply is ligated and cut at the root of the mesentery, and the margin of resection should be no less than 10cm. Complete resection of the mesocolon (CME) is performed in conjunction.
