目的

探索BRAF激活的非蛋白编码RNA(BANCR)在胰腺癌组织及血液中的表达,评估其作为淋巴结转移及预后生物标志物的潜力。

方法

回顾性分析68例接受根治性手术的胰腺癌患者临床资料。采用实时荧光定量聚合酶链反应(qRT-PCR)检测配对的肿瘤组织与癌旁正常胰腺组织、血清样本中BANCR表达水平;通过免疫荧光法评估肿瘤组织微淋巴管密度(MLVD)。应用SPSS 25.0统计学软件进行数据分析,采用配对样本t检验比较胰腺癌组织与癌旁组织之间差异,独立样本t检验比较LNM(+)与LNM(-)组间差异,Spearman相关分析评估BANCR与MLVD的相关性,ROC曲线分析诊断效能,Kaplan-Meier法进行生存分析。

结果

肿瘤组织中BANCR表达显著高于癌旁正常组织,且与淋巴结转移呈正相关。外周血BANCR水平在淋巴结转移患者中显著升高。术前外周血BANCR高表达对不良预后的预测效能强于CA199。

结论

伴淋巴结转移的胰腺癌患者外周血中BANCR表达显著高于无转移患者,提示BANCR可能成为胰腺癌淋巴结转移预测及预后评估的新型生物标志物。

Objective

This study aimed to explore the expression of BRAF-activated non-protein coding RNA (BANCR) in pancreatic cancer tissues and blood, and evaluate its potential as a biomarker for lymph node metastasis and prognosis.

Methods

Clinical data of 68 patients with pancreatic cancer who underwent radical surgery were retrospectively analyzed. Real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) was used to detect BANCR expression levels in paired tumor tissues, adjacent normal pancreatic tissues, and serum samples. Microlymphatic vessel density (MLVD) in tumor tissues was evaluated by immunofluorescence. Paired sample t test was used for statistical analysis to compare differences between pancreatic cancer tissues and adjacent tissues, independent sample t test for differences between LNM(+) and LNM(-) groups, Spearman correlation analysis to assess the correlation between BANCR and MLVD, ROC curve analysis for diagnostic efficacy, and Kaplan-Meier method for survival analysis.

Results

BANCR expression in tumor tissues was significantly higher than that in adjacent normal tissues, and was positively correlated with lymph node metastasis. Peripheral blood BANCR levels were significantly elevated in patients with lymph node metastasis. Preoperative high expression of peripheral blood BANCR showed stronger predictive efficacy for poor prognosis than CA199.

Conclusion

Peripheral blood BANCR expression in pancreatic cancer patients with lymph node metastasis is significantly higher than that in patients without metastasis, suggesting that BANCR may serve as a novel biomarker for predicting lymph node metastasis and evaluating prognosis in pancreatic cancer.
