Summary
Brief summary (as posted)
The objective of this randomized controlled, prospective clinical study, composed of 5 groups, G1, G2, G3, G4 and G5 is \[Evaluate the intestinal microbiota profile, nutritional, immunological status and inflammatory profile, before and after total or partial removal surgery (gastrectomies) for gastric cancer, in a patient using probiotic supplements.\] The main questions it aims to answer are: * probiotics are capable of modulating the immune response and microbiota in cancer patients who will undergo surgery * surgery itself alters the immunological pattern and microbiota of cancer patients Participants will be divided into groups for evaluation and the G1 intervention group will take probiotic capsules. The researchers will compare groups G1, G2 with G3 (negative control group) to see if there are differences between using probiotics or not, in controlling the immune response and if there are significant changes in their intestinal microbiota. Groups G4 and G5 will also be compared, where in these we will only measure the power of the use of probiotics in reducing surgical complications in the postoperative period.
