Predictive factors of large liver cell carcinoma tumor response after first conventional transarterial chemoembolization in Indonesia according to the modified response evaluation in solid tumors criteria: a preliminary study
Background: Various factors affect the response of large hepatocellular carcinoma (HCC) after transarterial chemoembolization (TACE), and the high demand for TACE procedures highlights the need for information and methods on the criteria for patient selection.Methods: Thirty-six HCC patients who were treated with conventional TACE between January 2014 and January 2020 and had pre- and postoperative imaging data were included in the analysis. The patients were categorized as tumor responders (complete or partial response) or nonresponders (stable or progressive disease) according to the modified response evaluation criteria in solid tumors (mRECIST). Eight predictive factors (Tumor diameter, Tumor amount, tumor vascularity, portal vein invasion, tumor location, presence of tumor capsule, Child–Pugh class, and alpha-fetoprotein (AFP) level) of tumor response were evaluated using multivariate analysis with logistic regression.Results: Only 42% of patients fell into the category of responders after conventional TACE. None of the Child–Pugh class B patients showed a tumor response. A multivariate analysis of the Child–Pugh class A patient group showed that a lesion diameter of 5–10 cm (OR: 8.78, 95% CI: 1.73–44.55; P = 0.009) are an independent predictor of tumor response after the first TACE procedure.Conclusions: A tumor diameter of 5–10 cm could be use as a predictor of tumor response after the first conventional TACE in Child–Pugh A patients, further researches are needed to confirm this finding.
