Abstract

This study was carried out to determine the prognostic significance of preoperative peripheral epithelial cell adhesion molecule- positive (EpCAM (+)) circulating tumor cell (CTC) and T regulatory (Treg) cell levels in hepatocellular carcinoma (HCC) patients for the prediction of postoperative recurrence following curative resection. A total of 49 patients about to undergo curative resection for HCC were recruited into the study. PCR and FACS were used to detect the preoperative levels of EpCAM (mRNA+) CTCs and CD4(+)CD25(+)Foxp3(+) Treg cells. The prognostic value of EpCAM (mRNA+) CTCs, CD4(+)CD25(+)Foxp3(+) Treg cells, and other clinicopathological factors were analyzed by applying the Kaplan-Meier method and the multivariate Cox proportional hazards model. The number of EpCAM (mRNA+) CTCs and Treg/CD4(+) cells showed significant correlation as prognostic factors of postoperative HCC recurrence: EpCAM (mRNA+) CTC ≥ 2.22 (P = 0.001) and Treg/CD4(+) ≥ 5.07 (P = 0.045), with EpCAM (mRNA+) CTC ≥ 2.22 (P = 0.003, HR = 6.668) being the most important indicator. Patients with high CTC/Treg levels showed a significantly higher risk of developing postoperative HCC recurrence than those with low CTC/Treg levels (66.7 % vs. 10.3 %, P < 0.001). The high CTC/low Treg group also presented higher 1-year recurrence rates compared with the low CTC/low Treg level group (50.0 % vs. 10.3 %, P = 0.004). Elevated EpCAM (mRNA+) CTC and Treg/CD4(+) levels were associated with early recurrence of HCC, indicative of poor clinical outcome. The combined detection of EpCAM (mRNA+) CTC and Treg/CD4(+) may therefore provide a novel prognostic predictor for HCC patients.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. 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 15 October 2017.
All research outputs
#9,169,227
of 11,945,047 outputs
Outputs from BMC Cancer
#2,584
of 4,370 outputs
Outputs of similar age
#172,856
of 265,761 outputs
Outputs of similar age from BMC Cancer
#123
of 248 outputs
Altmetric has tracked 11,945,047 research outputs across all sources so far. This one is in the 20th percentile – i.e., 20% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,370 research outputs from this source. They receive a mean Attention Score of 3.9. This one is in the 33rd percentile – i.e., 33% of its peers scored the same or lower than it.
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 265,761 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 29th percentile – i.e., 29% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 248 others from the same source and published within six weeks on either side of this one. This one is in the 44th percentile – i.e., 44% of its contemporaries scored the same or lower than it.
