It highlights the interactions between gastrointestinal probiotics, including Lactobacillus, and Helicobacter pylori infection, emphasizing their roles in gastric cancer initiation and progression. The article evaluates how probiotics exert anticancer effects by restoring intestinal microecological balance, enhancing mucosal immunity, and suppressing H. pylori. It also discusses preliminary findings on Lactobacillus in colorectal cancer and their potential relevance to gastric cancer research. Finally, the clinical potential of combining probiotics with immunotherapy for gastric cancer is assessed, and future research directions in this rapidly evolving field are proposed.<\/jats:p>","DOI":"10.31083\/fbl48167","type":"journal-article","created":{"date-parts":[[2026,7,30]],"date-time":"2026-07-30T12:17:49Z","timestamp":1785413869000},"source":"Crossref","is-referenced-by-count":0,"title":["Probiotic-Mediated Immune Regulation in Gastric Cancer: Mechanisms, Synergies With Immunotherapy, and Future Directions"],"prefix":"10.31083","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4464-9285","authenticated-orcid":true,"given":"Na","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Oncology, Lanzhou University Second Hospital, 730000 Lanzhou, Gansu, China"},{"name":"School of Life Sciences, Lanzhou University, 730000 Lanzhou, Gansu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-5934-661X","authenticated-orcid":true,"given":"Feixue","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Oncology, Lanzhou University Second Hospital, 730000 Lanzhou, Gansu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-3321-4339","authenticated-orcid":true,"given":"Hao","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Oncology Surgery, Lanzhou University Second Hospital, 730000 Lanzhou, Gansu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2931-7565","authenticated-orcid":true,"given":"Xiangkai","family":"Li","sequence":"additional","affiliation":[{"name":"School of Life Sciences, Lanzhou University, 730000 Lanzhou, Gansu, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2026,7,17]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","unstructured":"Sung H, Ferlay J, Siegel RL, Laversanne M, Soerjomataram I, Jemal A, et al.
