Background/Aim:
Intrahepatic cholangiocarcinoma (IHCC) is characterized by poor prognosis, and postoperative recurrence remains a problem. Thus, prognostic markers for IHCC are greatly needed. Recently, inflammatory factors were reported to be related to tumor progression and recurrence in various cancers. Therefore, the present study aimed to evaluate the prognostic ability of inflammatory factors.
Materials And Methods:
Forty-four patients with mass-forming IHCC (m-IHCC) were retrospectively evaluated and the correlations between inflammatory markers, including neutrophil-to-lymphocyte ratio and, modified Glasgow prognostic score, and patient survival were assessed.
Results:
The absolute neutrophil count (ANC) was significantly higher in the recurrence group than in the non-recurrence group (p=0.00568) and the most significant prognostic factor by multivariate analysis. Poor recurrence-free survival (RFS; p=0.00452) and cancer-specific survival (CSS; p=0.0323) were associated with high neutrophil levels. Moreover, neutrophil infiltration in the tumor site was positively correlated with ANC.
Conclusion:
ANC is associated with poor RFS, and could be used to predict recurrence in patients with m-IHCC.

Mean Absolute Deviation
Let us consider a dataset containing the number of unsold cupcakes in five shops: 10, 15, 8, 7, and 10. Initially, calculate the sample mean. Then calculate the deviation, or the difference, between each data value and the mean. Next, the absolute values of these deviations are added and divided by the sample size to...

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
