Radiofrequency-assisted Hepatectomy on the Outcomes of HCC Patients With Cirrhosis

Not Applicable

• Conditions: Hepatocellular Carcinoma; Cirrhosis
• Interventions: Procedure: Radiofrequency-assisted Hepatectomy; Procedure: Conventional Hepatectomy

• Registration Number: NCT01992978
• Lead Sponsor: Southwest Hospital, China

Brief Summary

Surgical resection is the most effective treatment of primary and secondary liver tumors. Technical innovations have mainly focused on minimizing bleeding during transection of the hepatic parenchyma because excessive hemorrhage and the need for blood transfusion are associated with increased postoperative morbidity and mortality. Recently,radiofrequency-assisted（RFA）hepatectomy has developed rapidly and gained widespread acceptance for the treatment of hepatocellular carcinomas（HCC），but its influence on the prognosis of HCC patients，especially for those with cirrhosis，is still controversial. Therefore, we design this prospective clinical trial to explore the effect of RFA hepatectomy versus the conventional hepatectomy on the outcomes of perioperative period and prognosis of HCC patients with cirrhosis.

Arm && Interventions

Group	Intervention	Description
radiofrequency-assisted resection group（RF-R)	Radiofrequency-assisted Hepatectomy	Radiofrequency-assisted resection: separating the tumor from liver by using the probe of radiofrequency to block the arterial and vessels before parenchymal transection.
conventional liver resection group（CLR-R）	Conventional Hepatectomy	Conventional liver resection group: hepatectomy only without RF assisted during parenchymal transection.Separating and dissecting the tumor with the routine clamp-crushing technical.

Primary Outcome Measures

Name	Time	Method
Postoperative liver injury	postoperative 90 days	The degree of postoperative hepatic injury is assessed by daily measurements of postoperative aminotransferase (AST) and alanine aminotransferase (ALT) levels, serum bilirubin levels, and prothrombin times. Each patient is followed up within postoperative 90 days.

Secondary Outcome Measures

Name	Time	Method
Number of Participants with Adverse Events	postoperative 90 days	It is evaluated according to the the Clavien-Dindo Classification of surgical complications. Postoperative mortality and morbidity are measured.
Overall survival	1,3,5-year overall survival
