Abstract:

Objective

To systematically analyze the predictive value for lymph node metastasis of intrahepatic cholangiocarcinoma (ICC) based on preoperative radiomics.

Methods

Chinese searching words consisted of intrahepatic cholangiocarcinoma,lymph node metastasis,radiomics,imaging examination,CT,MRI,ultrasound and PET-CT. English searching words included intrahepatic cholangiocarcinoma,lymph node metastasis,radiomics,CT,MRI,ultrasonic and PET-CT. Relevant studies were searched in Chinese and international databases such as PubMed and CNKI from the inception date of the databases to March 1,2023,and the included studies were extracted and analyzed. Statistical description was expressed by frequency and percentage. The year of publication was illustrated by bar charts. The extracted radiomic data were presented in tables.

Results

15 articles were finally included,including 12 articles in English and 3 in Chinese. The year of publication was ranged from 2003 to 2023,with the largest number of articles (n=5) published in 2019. There were 14 retrospective cohort studies and 1 prospective cohort study.10 studies were performed in China,3 in South Korea and 2 in Japan. At present,radiomic analysis was mainly conduced for qualitative and quantitative data. Qualitative data included the number of tumors,tumor size,tumor site,vascular infiltration,lymph node size,whether satellite lesions,necrotic or cystic components and bile duct dilatation occurred or not,morphological classification,whether the margins of lesions were regular or not,whether hepatic capsule was retracted or not and whether visceral peritoneum was perforated or not,etc. The quantitative data consisted of CT value ratio,maximum standardized uptake value (SUV),maximum SUV ratio,Pyradiomics value,IBEX value and apparent diffusion coefficient(ADC),etc.

Conclusions

At present,qualitative and quantitative data are mainly employed in the field of preoperative radiomic research for ICC. Among them,qualitative data which comprise more parameters are fully utilized,whereas quantitative data consisting of less parameters are used in a single pattern.
