Abstract:
Objective To invcstigate the value of preoperative imaging morphologic classification in solitary small hepatocellular carcinoma treated by RFA.Methods The clinical data of 73 patients with small hepatocellular carcinoma who rcccivcd radiofrequency ablation at the Affiliated Drum Tower Hospital of Medical School of Nanjing University from January 2008 to December 2012 were analyzed retrospectively.The lesions were classified into three types according to gross appearance in preoperative contrast-enhanced computed tomography (CT):single nodular type (type 1);single nodular with extranodular growth type or confluent multinodular type (type 2);infiltrating type (type 3).Thc clinicopathological features of patients with 3 types of tumors were compared by statistical methods.Patients were followed up via outpatient examination and telephone interview up to August 2014 or death.Results There were 24 cases of type 1,35 cases of type 2,14 cases of type 3,and the proportion were 20.2％,32.9％,47.9％,19.2％,respectively.The preoperative alpha-fetoprotein of type 3 was significantly higher than othcr types.The disease-free survival time of the three types were (37.2 ± 3.3) months,(20.9 ± 4.0) months,(14.4 ±4.9) months.The prognosis of the irregular types (type 2,type 3) is poor than the regular types (type 1).The overall survival time were (72.5 ± 4.7) months,(66.2 ± 7.3) months,(31.2 ± 5.3) months.The type 3 was the worst.The results of univariate analysis showed that morphologic classification,preoperative AFP,tumor size were related factors affecting the prognosis of patients (P ＜ 0.05).The results of multivariate analysis showed that morphologic classification was the independent risk factors affecting the prognosis of patients (P ＜ 0.05).Conclusion The preoperative imaging morphologic classification is the independent risk factors affecting the prognoses of patients with small HCC,which is help to choose the best treatment for patients with small hepatocellular.
