Abstract:
Objective:To study the use of perfluorobutane contrast-enhanced ultrasound (CEUS) in preoperative detection of microvascular invasion (MVI), and postoperative short-term recurrence of hepatocellular carcinoma (HCC).Methods:Patients who underwent hepatectomy with curative intent at the Chinese PLA General Hospital from January 2021 to April 2021 were prospectively enrolled into this study. Of 42 patients in this study, there were 36 males and 6 females, with age of (56.51±11.95) years old. All patients underwent preoperative perfluorobutane CEUS, and the characteristics of ultrasound, the vascular phase and Kupffer phase of perfluorobutane CEUS were recorded. Based on the pathological results, these patients were divided into the MVI and non-MVI groups. These patients underwent liver MRI once every 3 months postoperatively to diagnose tumor recurrence. According to the recurrence of HCC 6 months after operation, these patients were divided into the non-recurrence and the recurrence groups. Independent risk factors for MVI and short-term recurrence were analyzed by univariate and multivariate analyses.Results:Two patients had two lesions, and the remaining 40 patients had a single lesion. The pathological diagnosis of all the lesions were HCC (14 patients in the MVI group and 28 patients in the non-MVI group). The median follow-up was 6 (3, 6) months, and there were 8 patients in the recurrence group and 34 patients in the non-recurrence group. On logistic analysis, independent risk factors for MVI included the number of vessels detected on color Doppler flow imaging (CDFI) ( OR=5.762, 95% CI: 1.597-20.785, P=0.007), increased tumor size by more than 10% after CEUS arterial enhancement ( OR=10.186, 95% CI: 3.647-28.447, P=0.037), and thickness of corona enhancement at Kupffer phase of greater than 5 mm ( OR=17.340, 95% CI: 6.124-49.095, P=0.040). Cox regression showed the independent risk factors for short-term recurrence to include the number of vessels in CDFI ( RR=7.519, 95% CI: 1.086-52.051, P=0.041) and thickness of corona enhancement at Kupffer phase of greater than 5 mm ( RR=10.623, 95% CI: 1.265-89.218, P=0.030). Conclusion:Preoperative perfluorobutane CEUS had potential values in detecting MVI and in predicting postoperative short-term recurrence of HCC.
