Brief Summary

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

The human intestine is colonized with a complex microbial community and forms a super organism with the human body. Intestinal microorganisms include more than 1,000 kinds of bacterias, and their flora is very complex and functions are very diverse. The intestinal flora affects the body's nutrition, immunity and metabolism through interaction with the human body and the external environment, and is closely related to multiple systems. When the flora structure and function are changed, it will lead to the occurrence of various diseases or increase the risk of disease. In recent years, the role of intestinal microbes in tumorigenesis and development, as well as the role of diagnosis and treatment have been paid more and more attention. Abnormal intestinal flora can not only promote tumorigenesis, but also affect radiochemotherapy and immunotherapy effects. It is worth noting that the huge impact of the intestinal flora on immunotherapy suggests that immune checkpoint inhibitors can maximize the efficacy by protecting the balance and diversity of the intestinal microecology. Therefore, in this study, quantitative analysis of the diversity and abundance of intestinal, urinary tract flora, and urine components before and after adjuvant chemotherapy in patients with gastric and bowel cancer was performed. The link between treatment efficacy and prognosis.

Intervention Type DRUG

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.
