Diagnostic value of neuronal pentraxin II methylation in patients with pancreatic cancer: Meta-analysis.

Abstract

BACKGROUND:

Pancreatic cancer (PC) is a devasting disease of which mortality almost parallels its incidence. PC tissue may express aberrantly methylated neuronal pentraxin II (NPTX2), but it is unclear what the consequences of this are.

METHODS:

We systematically searched PubMed, Web of Science, the Chinese National Knowledge Infrastructure (CNKI), from inception to July 15, 2020, to identify if the detection of methylated NPTX2 have sufficient sensitivity and specificity to identify PC from other benign pancreatic diseases.

RESULTS:

Majority of the studies obtained samples from pancreatic juice by endoscopy or surgery and composed of population with chronic pancreatitis, benign cystic lesion, intraductal papillary mucinous neoplasm, and healthy controls. Our results demonstrated that the diagnostic value of methylated NPTX2 is of widely various sensitivity and specificity and it shown higher specificity in differentiate PC from benign diseases. The lab method of quantitative real-time methylation-specific PCR (QMSP) has higher specificity than real-time methylation-specific PCR (MSP) in detecting the indicator.

CONCLUSIONS:

NPTX2 methylation could serve as a promising molecular biomarker for pancreatic cancer diagnosis, for its high diagnostic value in differentiating pancreatic cancer from benign pancreatic disease with the lab method. The variable sensitivity of methylated NPTX2 was multifactorial, and it must be promoted before applied as screening test in clinical practice. Furthermore, experiments on methylated NPTX2 were needed to expanded for lower the heterogeneity.
