• It has been reported that HOXA transcript at the distal tip (HOTTIP) is dysregulated in various cancers. We performed this meta-analysis to clarify its promising functions as a prognosis marker in malignant tumors. The electronic databases, including PubMed, Medline, OVID, Cochrane Library, and Web of Science were searched from inception to September 23, 2016. The hazard ratio (HR) and 95% confidence interval (CI) were calculated to explore the relationship between HOTTIP expression and overall survival (OS), which were extracted from the eligible studies. The odds ratio (OR) was calculated to assess the association between HOTTIP expression and pathological parameters by using RevMan5.3 software. Seven studies were included in the study, with a total of 652 patients. The pooled HR suggested that high HOTTIP expression was significantly correlated with poor OS (HR=2.16, 95% CI: 1.69–2.76, P<0.00001) in cancer patients without obvious heterogeneity. The results showed there was a significant difference in the incidence of lymph node metastasis (LNM) between high HOTTIP expression group and low HOTTIP expression group (OR=2.30, 95% CI: 1.58–3.35, P<0.0001). A similar result was observed in the association between HOTTIP expression and distant metastasis (DM), the odds ratio was 3.30 (95% CI: 1.78–6.12, P=0.0001) without obvious heterogeneity. In addition, high HOTTIP expression was significantly associated with high tumor stage (OR=3.30, 95% CI: 0.25–0.64) without heterogeneity. This meta-analysis demonstrated that high HOTTIP expression significantly predicts poor OS, lymph node metastasis, distant metastasis and tumor stage, suggesting that high HOTTIP expression may serve as a novel biomarker for poor prognosis in cancers. •High expression HOTTIP was associated with shorter OS in cancer patients.•Higher expression of HOTTIP increased the risk of LNM, DM and high tumor stage in cancer.•HOTTIP expression can be a useful prognostic biomarker in human cancers.
