Description
Inclusion Criteria:
- Age 18-70 years old, male or female
- Surgery specimens were clearly diagnosed as gastric cancer and colon cancer by histopathology
- The operation method is not limited (both laparoscopic surgery and open surgery)
- After the perioperative period, stop using antibiotics for not less than 2 weeks
- It is planned to receive a chemotherapy regimen with a combination of platinum and fluorouracil for a period of 21 days (gastric cancer is the SOX or XELOX regimen, and colon cancer is the XELOX or FOLFOX regimen)
- Blood routine, biochemical and other related laboratory tests showed no obvious abnormalities
- There are no contraindications for related adjuvant chemotherapy indications.
Exclusion Criteria:
- Neoadjuvant treatment before gastric and bowel cancer surgery
- Previous history: He has suffered from intestinal microecology-related diseases such as cirrhosis, ulcerative colitis, Crohn's disease, irritable bowel syndrome, and urinary system diseases
- Before the perioperative period, because of anastomotic fistula and gastrointestinal perforation, reoperation
The following drugs were used within 2 weeks before enrollment:
- Various antibiotics, including antifungals (oral and intravenous)
- Probiotic preparations, various prebiotic preparations, etc c Glucocorticoids; d Take drugs known to have a significant effect on the intestinal and urethral flora within half a year (such as proton pump inhibitors, purgatives, bismuth, adsorbents, non-steroidal anti-inflammatory drugs, etc.)
- Other situations that the researcher considers unsuitable to participate in the experiment;

EXPERIMENTAL: treatment group

Form、dosage and frequency: Gastric cancer was given the SOX regimen (oxaliplatin + tegafur regimen,oxaliplatin 130mg/m2 intravenous infusion, the 1st day; tegafur 80mg/ m2/d orally Bid, the 1st to 14th day, every 21 days is one cycle) or XELOX regimen (oxaliplatin + capecitabine regimen,oxaliplatin 130mg/m2 intravenous infusion, the 1st day; capecitabine 1000mg/m2/d orally Bid, the 1st to 14th day, every 21 days is one cycle). Colon cancer was given the XELOX regimen (the dosage、frequency and administration are the same as the gastric cancer) or FOLFOX regimen (oxaliplatin + calcium folinate + fluorouracil regimen,oxaliplatin 85mg/m2 intravenous infusion, the 1st day; calcium folinate 400 mg/m2 intravenous infusion, the 1st day; fluorouracil 400 mg/m2 intravenous infusion, the 1st day, then 1200 mg/m2/d × 2d continuous intravenous infusion,every 14 days is one cycle). Duration:through chemotherapy completion,about six months. |
