A Machine-learning Model to Predict Lymph Node Metastasis of Intrahepatic Cholangiocarcinoma

West China Hospital483 enrolled

Overview

The object of this study is to develop a model for prediction of lymph node metastasis among intrahepatic cholangiocarcinoma (ICC) patients. Intrahepatic cholangiocarcinoma is the second most common kind of primary liver cancer, accounting for approximately 10%-15%. There is a lack of agreement regarding the necessity of performing lymph node dissection (LND) in patients with ICC. Currently, the percentage of LND is below 50%, and the rate of sufficient LND (≥6) has plummeted to less than 20%. Consequently, a large proportion of patients are unable to acquire LN status, which hinders the following systematic treatment strategies after surgery:. Therefore, our objective is to construct a LN metastasis model utilizing machine learning techniques, including patients' clinical data and pathology information, with the goal of offering a reference for patients who have not undergone LND or have had inadequate LND.

Outcomes

Primary Outcomes

Overall survival

Overall survival (OS) refers to the duration between the commencement of surgery and the patient's demise due to any reason.

Time frame: 2010.01-2019.01

Secondary Outcomes

Disease free survival

Disease-free survival (DFS) refers to the period of time from the date of surgery until the occurrence of a relapse either within or outside the liver.
