Effect of Intraoperative Controlled Release 5-Fluorouracil Therapy on Recurrence in Hepatocellular Carcinoma Patients

Not Applicable

• Conditions: Recurrence; Hepatocellular Carcinoma
• Interventions: Procedure: Hepatectomy; Drug: 5-Fluorouracil

• Registration Number: NCT02523053
• Lead Sponsor: Eastern Hepatobiliary Surgery Hospital

Brief Summary

The aim of this study is to confirmed the role of intraoperative controlled release 5-Fluorouracil therapy in the prevention of recurrence after surgery for HCC patients with high risk of preoperative prediction of microvascular invasion.

Detailed Description

Surgical resection is the major curative treatment for patients with hepatocellular carcinoma (HCC). However, the postoperative 5-year recurrence rate after surgical resection was significantly high, which has been reported to 40%-70%.

Recurrence after surgery is the main factor affecting the efficacy of management of hepatocellular carcinoma, however, there are few methods for the prevention of recurrence and no standard treatment for recurrent HCC following curative-intent initial surgery has been established so far. The effective prevention of recurrence is the key to improve the management of HCC.

Previous studies showed the prevalence of microvascular invasion (MVI) in one of the critical and negative prognostic factors for HCC patients after partial hepatectomy or liver transplantation. For the early stage HCC patients, preoperative prediction of MVI is helpful to identify the appropriate object of anti-recurrence treatment before or after operation.

Our another previous study established a nomogram for MVI prediction of early HCC patients, which can preoperative efficiently predict the occurrence of MVI within Milan criteria, has been published online in JAMA surgery. On the other hand, there are only few studies reported the use of controlled release 5-Fluorouracil in the treatment of digestive tract tumors.

The action time of the controlled release 5-Fluorouracil particles is more than 15 days, the diffusion radius is 4-6cm. In theory, during the operation, the drug can be given to any location that may have tumor residues, timely and conveniently, and has a long time to maintain a high drug concentration, which is conducive to kill small metastatic foci caused by MVI. However, to our best knowledge, there is no evidence of high levels of evidence-based medical evidence to confirm the value of controlled release 5-Fluorouracil in the prevention of HCC recurrence.

In view of this, we aim to implement a randomized controlled study to confirmed the role of intraoperative controlled release 5-Fluorouracil therapy in the prevention of recurrence after surgery for HCC patients with high risk of preoperative prediction of microvascular invasion.
