BackgroundLong noncoding RNA (lncRNA) is a significant component of the noncoding genome and refers to RNA molecules that exceed 200 nucleotides in length. It plays a crucial role in both promoting and suppressing cancer by regulating the proliferation, invasion, and metastasis of tumor cells. We have found a correlation between cancer susceptibility candidate 11 (CASC11) experssion and tumorigenesis development prognosis in a number of studies on tumors. Hence, this meta-analysis was conducted to further investigate the effects of CASC11 expression on clinicopathological features and outcome. Furthermore, CASC11 can act both as a therapeutic target and a cancer biomarker.MethodWe conducted a thorough search of PubMed, Embase, Web of Science, and Cochrane Library to identify all eligible studies until September 20, 2023. These studies examined the potential relationship between the expression levels of CASC11 and survival or the range of pathological feature in cancer patients. The impact of CASC11 expression on overall survival (OS) was evaluated using pooled hazard ratios and 95% confidence intervals (CI). The relationship between CASC11 expression and clinicopathological features was assessed through pooled odds ratios and 95% CI.ResultsA total of 11 studies, involving 660 patients, were examined in this analysis. The results revealed that the overexpression of CASC11 was significantly associated with poor OS (hazard ratios = 2.07, 95%CI = 1.64-2.60) in cancer. Further subgroup analysis demonstrated that the overexpression of CASC11 was consistently linked to poorer OS in diverse types of cancer, including digestive system neoplasm, respiratory neoplasms, and gynecologic tumor.ConclusionOverall, this analysis established a strong correlation between CASC11 expression and tumor prognosis, suggesting its potential as a predictive marker for tumor progression in diverse cancer types.Copyright © 2024 the Author(s).
