Objectives

Narrative objectives1

The aim of this study is to validate whether the anatomic classification in peripheral and proximal type of intrahepatic cholangiocarcinoma (iCCA) is a useful classification that can predict prognosis after resection of iCCA, lymph node metastasis of iCCA, and curative resection through an international multicenter study.

BACKGROUND:
In the 2019 WHO classification,iCCA was pathologically subclassified into two types, depending on whether it derives from small or large bile ducts.The difference in bile duct location where iCCA occurs affects the biological characteristics of iCCA. In recent years, the usefulness of classification based on the anatomical location of iCCA has been focused on. The difference in bile duct location where iCCA occurs affects the biological characteristics of iCCA. In recent years, the usefulness of classification based on the anatomical location of iCCA has been focused on. The iCCA located in the peripheral region of the liver have reported less invasion, less lymph node (LN) metastasis, and better prognosis compared to that of iCCA located in the proximal or central region. However, these studies were conducted at a single institution, with a small number of cases, and lacking a fixed definition of `proximal` and `distal`; thus, reaching a consensus was difficult. In our current study, we will investigate the impact of the anatomical classification of iCCA based on the relationship between Glissonean pedicles (GP)from an oncological perspective.

METHODOLOGY:
A case report form (CRF) will be distributed to the Japanese and Korean authorities. Data on patient characteristics, preoperative CT findings, surgical outcomes, and prognosis will be collected.

Contact and invasion of iCCA with glissonean pedicle (GP) is evaluated by contrast-enhanced CT or MRI.

Definitions of iCCA-Glissonean pedicle contact and invasion:
Negative: Tumor and GP are clearly separated or normal tissue is seen between tumor and GP.
Positive: Tumor contacts with GP at any point. Tumor clearly invades GP. Tumor and GP are separated but the surrounding invasion extends into GP. Tumor and GP are separated but there is deformation in GP near the tumor and peripheral bile duct extension. An investigator can use CENTRAL REVIEW.
