Prognostic significance of indocyanine green fluorescence patterns in resected hepatocellular carcinoma: a retrospective analysis of prospectively collected data

Purpose

Indocyanine green (ICG) fluorescence imaging enables intraoperative visualization of liver tumors and reflects distinct tumor biology according to uptake patterns. However, its prognostic significance in hepatocellular carcinoma (HCC), particularly in relation to resection margins, remains unclear. This study evaluated the impact of ICG fluorescence patterns on recurrence-free survival (RFS) after curative resection for HCC.
