Liver Resection Versus Transarterial Chemoembolization for the Treatment of Intermediate-stage Hepatocellular Carcinoma

Summary

The role of transarterial chemoembolization (TACE) as the standard therapy for intermediate-stage hepatocellular carcinoma (HCC) is being challenged by increasing studies which showed that liver resection (LR) is a safe and feasible procedure with better survival outcomes than TACE does.

In light of this, the investigators have constructed a Markov model to simulate comparing LR and TACE in the treatment of intermediate-stage HCC. The results suggested that LR may provide survival benefit over TACE for the treatment of intermediate-stage HCC in cirrhotic patients. However, validating the simulated result by a study with higher quality (e.g. prospective clinical trial) would be of great value in providing a more convincing finding. Therefore, based on the established Markov model, the investigators aimed to prospectively compare the treatment efficacy and safety of LR with TACE for consecutive patients with intermediate-stage HCC.

Conditions

• Hepatocellular Carcinoma

Interventions

PROCEDURE

liver resection

Intraoperative ultrasound was routinely used during surgery. Anatomic resection was carried out in the form of segmentectomy or/and subsegmentectomy.In segmentectomy, the hepatic parenchyma was transacted at the intersegmental plane as described by Couinaud. If the hepatic parenchymal transaction plane needed to go beyond the intersegmental plane to achieve the desired extent of resection margin, the small portal branches supplying the liver parenchyma up to the intended transaction plane were punctured under US guidance and injected with methylthioninium chloride, and then liver subsegmentectomy was performed either alone or in combination with segmentectomy along the plane of demarcation as delineated by the injected methylthioninium chloride. Nonanatomic resection with a negative resection margin was performed when anatomical resection may cause inadequate liver remnant. Pringle's maneuver was used if necessary with a clamp/unclamp time of 10 min/5 min.

PROCEDURE

transarterial chemoembolization

A microcatheter was inserted into the feeding arteries as selectively as possible through the lobar, segmental, or subsegmental arteries, dependent on the tumor distribution and hepatic functional reserve. Hepatic artery infusion chemotherapy was performed using 300 mg carboplatin. Subsequently, chemolipiodolization was performed mixed with 5 ml of lipiodol. According to the number and size of the lesions, and liver and kidney function of the patient, the chemotherapeutic agents, including epirubicin (50-100 mg), pirarubicin (30-50 mg), hydroxycamptothecin (10-30 mg) and fluorouracil (500-1000 mg), were determined by the multidisciplinary team. If residual flow remained after infusion of these agents, additional lipiodol was injected. Embolization was performed with absorbable gelatin sponge particles 350-560 μm in diameter.

DRUG

carboplatin

Hepatic artery infusion chemotherapy was performed using 300 mg carboplatin (Bristol-Myers Squibb, New York, NY).

DRUG

lipiodol

Chemolipiodolization was performed mixed with 5 ml of lipiodol (Lipiodol Ultra-Fluide; André Guerbet Laboratories, Aulnay-sous-Bois, France).

DRUG

epirubicin , pirarubicin , hydroxycamptothecin and fluorouracil

The chemotherapeutic agents, including epirubicin (50-100 mg), pirarubicin (30-50 mg), hydroxycamptothecin (10-30 mg) and fluorouracil (500-1000 mg), were determined by the multidisciplinary team.

OTHER

absorbable gelatin sponge particles

Embolization was performed with absorbable gelatin sponge particles (Gelfoam; Hangzhou Bi-Trumed Biotech Co., Ltd., Hangzhou, Zhejiang, China) 350-560 μm in diameter.
