Liver Decompensation Risk after Hepatectomy for HCC

Description

Calculates the risk of liver decompensation and liver-related mortality after partial hepatectomy for Hepatocellular Carcinoma (HCC). This hierarchical model stratifies patients into Low, Intermediate, and High risk categories based on the presence of portal hypertension, the extent of resection, and the MELD score.

Usage

liver_decompensation_risk_hcc(portal_hypertension, extent_hepatectomy,
                              meld_score)

Arguments

portal_hypertension	Numeric (0 or 1). Presence of clinically significant portal hypertension (e.g., esophageal varices, splenomegaly with platelets <100,000/uL). (1 = Yes).
extent_hepatectomy	String. Planned extent of liver resection. "minor": Removal of < 3 adjacent segments. "major": Removal of >= 3 adjacent segments.
meld_score	Numeric. Model for End-Stage Liver Disease (MELD) score (or MELD-Na). Threshold for risk stratification is > 9.

Value

A list containing:

Risk_Category	Classification (Low, Intermediate, High).
Est_Liver_Decompensation_Rate	Estimated probability of postoperative liver decompensation.
Est_Liver_Related_Mortality	Estimated probability of liver-related mortality.
