Abstract

The invention discloses a prediction method for clinical prognosis of a liver cancer patient based on machine learning. The method comprises the following steps: collecting corresponding sample data of hepatocellular carcinoma according to predetermined prediction characteristics; sorting the prediction features according to the sample data, and selecting part of the prediction features according to a sorting result; determining candidate prediction features related to the total survival rate from the selected prediction features by using a proportional risk regression model; and using a gradient enhanced survival classifier to select 20 optimal prediction features from the candidate prediction features as survival prediction factors to construct a liver cancer patient prognosis survival model. According to the invention, the HCC-related high-death-risk patients can be effectively identified.

Description

technical field [0001] The invention relates to liver cancer survival analysis technology, in particular to a method for predicting clinical prognosis of liver cancer patients based on machine learning. Background technique [0002] Liver cancer accounts for 8.2% of all cancer deaths worldwide. Major risk factors for hepatocellular carcinoma (HCC) include hepatitis B virus (HBV) or hepatitis C virus (HCV) infection and alcoholic or nonalcoholic liver disease. The clinical efficacy of patients with HCC largely depends on tumor burden, treatment modality, and liver function. A number of staging systems and predictive / prognostic models have been developed to assess liver functional reserve. [0003] To date, several staging systems have been used to predict the clinical efficacy of different approaches in HCC patients. In addition, liver function parameters, including Child-Pugh grading system, albumin and bilirubin levels, international normalized ratio (INR) and alkaline p...
