Preliminary studies suggest its association with poor prognosis, but evidence remains fragmented across cancer types. This meta-analysis aims to systematically evaluate the prognostic value of SARIFA for overall survival (OS) and its correlation with aggressive tumor phenotypes. Methods: Following PRISMA guidelines, we searched PubMed, Embase, Web of Science, and Cochrane up to December 2025. Studies reporting hazard ratios (HRs) for OS or odds ratios (ORs) for high-grade tumors related to SARIFA status were included. Data were pooled using Stata 12.0, and heterogeneity was assessed using I2 statistics. Subgroup, sensitivity, and publication bias analyses were performed. Results: Ten studies (6881 patients) showed that SARIFA positivity was significantly associated with worse OS (HR = 1.52, 95% CI: 1.42\u20131.63, I2 = 0.0%). Eleven studies (6847 patients) revealed that SARIFA positivity correlated with advanced tumor stage: pT (OR = 5.49), pN (OR = 2.80), pM (OR = 2.03), AJCC stage (OR = 4.04), and higher pathological grade (OR = 2.36). Heterogeneity was low for OS but substantial for pT (I2 = 87.4%), pM (I2 = 70.5%), and AJCC (I2 = 72.0%). Publication bias was absent for OS but present in pT- and AJCC-staging analyses. Trim-and-fill correction for pT indicated that statistical significance disappeared after imputing two missing studies (p changed from &lt;0.001 to 0.450), suggesting that this association is not robust. Evidence for pancreatic and prostate cancers remains limited, each represented by only one study. Conclusions: SARIFA positivity is a strong predictor of poor overall survival and is significantly associated with aggressive tumor phenotypes, including advanced pT, pN, pM, AJCC stage, and higher pathological grade, supporting its potential as a practical prognostic biomarker in solid tumors.<\/jats:p>","DOI":"10.3390\/jcm15176830","type":"journal-article","created":{"date-parts":[[2026,9,3]],"date-time":"2026-09-03T10:10:33Z","timestamp":1788430233000},"page":"6830","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Association of SARIFA with Poor Prognosis and Aggressive Tumor Phenotypes in Cancers: A Meta-Analysis"],"prefix":"10.3390","volume":"15","author":[{"given":"Jiaqi","family":"Lao","sequence":"first","affiliation":[{"name":"Department of Gastroenterology, The First Hospital of China Medical University, No. 155 North Nanjing Street, Heping District, Shenyang 110001, China"},{"name":"The First Clinical College, China Medical University, No. 77 Puhe Street, Shenbei New District, Shenyang 110122, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"given":"Guangwei","family":"Tian","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, The First Hospital of China Medical University, No. 155 North Nanjing Street, Heping District, Shenyang 110001, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"conceptualization","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5645-5595","authenticated-orcid":false,"given":"Lin","family":"Guan","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, The First Hospital of China Medical University, No. 155 North Nanjing Street, Heping District, Shenyang 110001, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"supervision","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,3]]},"reference":[{"key":"ref_1","first-page":"229","article-title":"Global cancer statistics 2022: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries","volume":"74","author":"Bray","year":"2024","journal-title":"CA A Cancer J.
