| Abstract |
Diagnosis of pancreatic cancer (PC) by using sensitive and specific biomarkers is considered necessary. MiRNAs are master regulators of gene expression and several biological processes, and they are dysregulated in various cancers, where they play a vital role in either cancer progression or suppression. So, this study was designed to investigate the role of plasma miR-22-3p, miR-642b-3p and miR-885-5p expression as possible diagnostic markers in PC patients as compared to serum CA19-9. In addition, the correlation of those miRNAs and CA19-9 with clinical characteristics of PC patients was analyzed. The expression levels of selected miRNAs and serum CA19-9 concentration were determined for 35 patients with PDAC and 15 healthy controls by quantitative real-time RT-PCR and electro-chemiluminescence immune assay, respectively. The sensitivities of miRNAs as biomarkers of PC were evaluated and compared with CA19-9 using a receiver operating characteristic analysis. The levels of three miRNAs (miR-22-3p, miR-642b-3p and miR-885-5p) and CA19-9 were significantly higher in PC patients, even those with early-stage disease (IB and IIB), than in healthy control. Both miRNAs and CA19-9 were associated with tumor stage. The high sensitivities of the three selected miRNAs and CA19-9 were observed. The measurement of miR-22-3p, miR-642b-3p and miR-885-5p may prove to have clinical utility in diagnosis of PC. Those miRNAs are ideal early biomarkers for PC diagnosis. So, they can effectively be used with serum CA19-9 for PC screening in early tumor stage. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 February 2018.
All research outputs
#7,855,444
of 23,815,455 outputs
Outputs from Journal of Cancer Research and Clinical Oncology
#601
of 2,632 outputs
Outputs of similar age
#115,559
of 323,652 outputs
Outputs of similar age from Journal of Cancer Research and Clinical Oncology
#10
of 38 outputs
Altmetric has tracked 23,815,455 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,632 research outputs from this source. They receive a mean Attention Score of 3.6. This one has gotten more attention than average, scoring higher than 53% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 323,652 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 50% of its contemporaries.
We're also able to compare this research output to 38 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 63% of its contemporaries.
