| Abstract |
There currently is only limited knowledge on the role of tumor-specific immunity in cholangiocarcinoma. This study evaluated the clinical implications of cytotoxic T lymphocyte antigen-4 (CTLA-4) expression levels and CD4(+) and CD8(+) tumor-infiltrating lymphocytes (TILs) in extrahepatic bile duct (EHBD) cancer. Immunohistochemistry of CTLA-4, CD4, and CD8 was performed for 77 EHBD cancer patients undergoing surgery plus adjuvant chemoradiotherapy. CTLA-4 expression on tumor cells and TILs were assessed by using H-scores and the proportion of CTLA-4(+) lymphocytes, respectively. With optimal cutoff values determined by a maximal chi-square method with overall survival (OS) data, patients with CTLA-4 H-score >70 and a proportion of CTLA-4(+) TILs >0.15 showed higher mean density of CD8(+) and CD4(+) TILs, respectively (P = 0.025 for CD8(+) and P = 0.055 for CD4(+) TILs). The high CTLA-4 H-score level was associated with prolonged OS and disease-free interval (DFI) (P = 0.025 and 0.004, respectively). With differential levels of CTLA-4 H-score according to hilar and non-hilar locations (high rate 32 vs. 68%, respectively; P = 0.013), an exploratory subgroup analysis demonstrated that the associations between the CTLA-4 expression and OS and DFI were confined to hilar tumors (P = 0.003 and <0.001, respectively), but not to non-hilar ones (P = 0.613 and 0.888, respectively). This study demonstrates a potential prognostic relevance of CTLA-4 expression in EHBD cancer. We suggest a differential survival impact of the CTLA-4 expression level according to different tumor locations. |

Attention Score in Context
This research output has an Altmetric Attention Score of 7. 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 19 August 2022.
All research outputs
#4,598,432
of 23,130,383 outputs
Outputs from Targeted Oncology
#57
of 557 outputs
Outputs of similar age
#93,954
of 422,510 outputs
Outputs of similar age from Targeted Oncology
#2
of 10 outputs
Altmetric has tracked 23,130,383 research outputs across all sources so far. Compared to these this one has done well and is in the 79th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 557 research outputs from this source. They receive a mean Attention Score of 2.8. This one has done well, scoring higher than 89% 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 422,510 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 77% of its contemporaries.
We're also able to compare this research output to 10 others from the same source and published within six weeks on either side of this one. This one has scored higher than 8 of them.
