PANDAR (promoter of CDKN1A antisense DNA damage activated RNA) has been shown to be aberrantly expressed in many types of cancer. Considering conflicting data, the current study was aimed to assess its potential role as a prognostic marker in malignant tumors. A comprehensive literature search of PubMed, Medline, and Web of Science was performed to identify all eligible studies describing the use of PANDAR as a prognostic factor for different types of cancer. Data related to overall survival (OS) and clinicopathologic features were collected and analyzed. The pooled hazard ratio (HR) and odds radio (OR) with a 95% confidence interval (CI) were used to estimate associations. Ten original studies containing 1,231 patients were included. The results showed that in patients with cancer, high PANDAR expression is correlated with lymph node metastasis (LNM; OR = 2.57; 95% CI, 1.76-3.81; p < 0.001), tumor stage (OR = 2.90; 95% CI, 1.25-6.75; p = 0.013), and tumor size (OR = 1.79; 95% CI, 1.11-2.91; p = 0.018). However, sensitivity analysis further demonstrated a significant association between high PANDAR expression and OS, both in multivariate and univariate analysis models (pooled HR 2.01; 95% CI, 1.17-3.44 and pooled HR 2.62; 95% CI, 1.98-3.47, respectively), after omitting one study. These results suggested that PANDAR expression might be indicative of advanced disease and poor prognosis in patients with cancer. Further studies are necessary to determine the value of this risk stratification biomarker in clinical management of patients with cancer.
PANDAR(CDKN1A 反义 DNA 损伤激活 RNA 的启动子)已在许多类型的癌症中显示出异常表达。考虑到相互矛盾的数据,本研究旨在评估其作为恶性肿瘤预后标志物的潜在作用。对 PubMed、Medline 和 Web of Science 进行了全面的文献检索,以确定所有描述 PANDAR 作为不同类型癌症预后因素的研究。收集并分析了与总生存期(OS)和临床病理特征相关的数据。使用合并的风险比(HR)和优势比(OR)及其 95%置信区间(CI)来评估关联。共纳入了 10 项包含 1231 名患者的原始研究。结果表明,在癌症患者中,高 PANDAR 表达与淋巴结转移(LNM;OR=2.57;95%CI,1.76-3.81;p<0.001)、肿瘤分期(OR=2.90;95%CI,1.25-6.75;p=0.013)和肿瘤大小(OR=1.79;95%CI,1.11-2.91;p=0.018)相关。然而,敏感性分析进一步表明,高 PANDAR 表达与 OS 之间存在显著关联,在多变量和单变量分析模型中均如此(合并 HR 2.01;95%CI,1.17-3.44 和合并 HR 2.62;95%CI,1.98-3.47),在排除一项研究后。这些结果表明,PANDAR 表达可能表明癌症患者的疾病进展和预后不良。需要进一步研究来确定这种风险分层生物标志物在癌症患者临床管理中的价值。
