AIM: To investigate the relationship between contrastenhanced ultrasound(CEUS),basic fibroblast growth factor(b FGF),endothelin-1(ET-1),and hepatocellular carcinoma(HCC) recurrence after ablation. METHODS: A total of 51 HCC patients(38 males and 13 females) who received radiofrequency ablation in our hospital from June 2012 to July 2014 were enrolled in this study. The patients were divided into two groups: recurrence group and non-recurrence group. Routine abdominal examination was first performed in the horizontal position. Then the patients underwent CEUS and immunohistochemical staining before receiving radiofrequency ablation. All patients were followed-up every three months for one year.The results of CEUS and serum tumor marker levels were evaluated and combined together to estimate HCC recurrence and metastasis. Patients were divided into two groups: recurrence group and non-recurrence group. Quantitative parameters of CEUS and tumor expression levels of b FGF and ET-1 were compared between the two groups,respectively. Binary logistic regression analysis was used to analyze the relationship between CEUS quantitative parameters,expression levels of ET-1 and b FGF,and HCC recurrence after ablation. RESULTS: Based on the quantitative parameters of CEUS before patients received radiofrequency ablation,the levels of tumor rise time(t RT),tumor time to peak(t TTP),tumor peak intensity(t PI) and tumorparenchymal peak intensity(t-p PI) in the recurrence group were significantly lower than those in the nonrecurrence group(16.6 ± 6.1 vs 23.2 ± 7.0,P = 0.000; 41.2 ± 10.2 vs 59.6 ± 14.2,P = 0.000; 23.8 ± 6.7 vs 31.4 ± 6.4,P = 0.000; 7.1 ± 3.4 vs 14.6 ± 7.4,P = 0.000; respectively). The expression levels of b FGF in the recurrence group were significantly higher than those in the non-recurrence group(P < 0.05). Levels of t TTP showed a significant inverse correlation with the level of b FGF in tumors(r =-0.312,P = 0.037). The Binary logistic regression analysis results revealed that the levels of t RT,t TTP,t PI and the level of b FGF were associated with HCC recurrence after radiofrequency ablation(P < 0.05). CONCLUSION: CEUS is a noninvasive and effective method for evaluating the angiogenesis of HCC,and predicting its recurrence and prognosis.
A study of the relationship between contrashanced ultrasound (CEUS), basic fibroblast growth factor (b FGF), endothelin-1 (ET-1), and hepatocellular carcinoma (HCC) recurrence after ablation.
