Abstract
Purpose
This study aimed to explore the association of preoperative magnetic resonance imaging (MRI) tumor morphological classification with early recurrence (ER) and overall survival (OS) after radical surgery of hepatocellular carcinoma (HCC).
Patients and Methods
A retrospective analysis of 296 patients with HCC who underwent radical resection was performed. On the basis of LI-RADS, tumor imaging morphology was classified into three types. The clinical imaging features, ER, and survival rates of three types were compared. Univariate and multivariate Cox regression analyses were conducted to identify prognostic factors associated with OS and ER after hepatectomy for HCC.
Results
There were 167 tumors of type 1, 95 of type 2, and 34 of type 3. In patients with type 3 HCC, postoperative mortality and ER were significantly higher than in patients with type 1 and type 2 (55.9% versus 32.6% versus 27.5% and 52.9% versus 33.7% versus 28.7%). In multivariate analysis, the LI-RADS morphological type was a stronger risk factor for predicting poor OS [hazard ratio (HR) 2.77, 95% confidence interval (CI) 1.59–4.85, P < 0.001] and ER (HR 2.14, 95% CI 1.24–3.70, P = 0.007). A subgroup analysis revealed that type 3 was associated with poor OS and ER in > 5 cm cases but not in < 5 cm cases.
Conclusions
ER and OS of patients with HCC undergoing radical surgery can be predicted using the preoperative tumor LI-RADS morphological type, which could help to select personalized treatment plans for patients with HCC in the future.
