| Abstract |
The indication of surgery in intrahepatic cholangiocarcinoma (ICC) patients with lymph node metastasis (LNM), macroscopic periductal infiltration (PI), and intrahepatic metastasis (IM) remains unclear. Patients who underwent resection for mass-forming (MF) dominant ICC and unresected patients caused by LNM, IM, or locally advanced tumors (UR group) were enrolled. The significance of CA19-9 was investigated in advanced ICC. Seventy-three patients who underwent resection and 20 UR patients were analyzed. Using the minimum p value approach based on the overall survival, the optimal CA19-9 cutoff value was 300 U/mL. The OS of the patients with CA19-9 < 37 U/mL (n = 26; MST, 49.6 months) and 37-300 U/mL (n = 28; MST, 45.1 months) was comparable (P = 0.842); however, the OS of the patients with CA19-9 = 37-300 U/mL was significantly better than that with CA19-9 ≥ 300 U/mL (n = 19; MST, 15.3 months; P < 0.001). CA19-9 > 300 U/mL, MF + PI, and IM were independently associated with OS. The OS of the patients with CA19-9 < 300 U/mL who developed LNM (MST, 34.0 months), MF + PI (MST, 32.9 months), or IM (MST, 35.2 months), or who required major vascular resection (MST, 45.1 months) was better than those with CA19-9 ≥ 300 U/mL who developed LNM (MST, 8.7 months; P = 0.005), MF + PI (MST, 7.5 months; P = 0.040), or IM (MST, 8.7 months; P = 0.001), or who required major vascular resection (MST, 14.8 months; P = 0.015); their prognosis was similar with the UR group. Even if patients had ICC developing LNM, PI, or IM, or require major vascular resection, surgical resection can be indicated for patients with CA19-9 < 300 U/mL. However, the indications for either adjuvant therapy or resection should be carefully determined in patients with CA19-9 ≥ 300 U/mL. |

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 06 April 2018.
All research outputs
#18,601,965
of 23,041,514 outputs
Outputs from World Journal of Surgery
#3,499
of 4,266 outputs
Outputs of similar age
#255,665
of 329,124 outputs
Outputs of similar age from World Journal of Surgery
#63
of 72 outputs
Altmetric has tracked 23,041,514 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,266 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.6. This one is in the 10th percentile – i.e., 10% 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 329,124 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 11th percentile – i.e., 11% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 72 others from the same source and published within six weeks on either side of this one. This one is in the 9th percentile – i.e., 9% of its contemporaries scored the same or lower than it.
