Role of mesohepatectomy with or without transcatheter arterial chemoembolization for large centrally located hepatocellular carcinoma

BACKGROUND: The role of preoperative transcatheter arterial chemoembolization (TACE) for resectable hepatocellular carcinoma (HCC) was controversial. METHODS: 246 patients with large centrally located HCC underwent mesohepatectomy (MH) and were divided into two groups: group A, 89 patients with preoperative TACE; group B, 157 patients without preoperative TACE. The aim was to evaluate the influence of preoperative TACE on postoperative complications and long-term results of patients with large centrally located HCC. RESULTS: In the 89 patients of the TACE-MH group, a total of 123 (mean 1.4 per patient) preoperative TACEs were performed. The differences in postoperative complications (34.8 vs. 24.2%; p=0.075) and overall hospital mortality (3.4 vs. 0.6%; p=0.103) between the two groups were not significant. The postoperative recurrence rate in the remnant liver was higher in the MH group than in the TACE-MH group (79.6 vs. 73.0%), while the extrahepatic metastasis rate in the TACE-MH group was higher than that in the MH group (11.1 vs. 7.0%). Overall 1-, 3-, and 5-year survival rates were 87.1, 62.9, and 46.2%, respectively, for the TACE-MH group, and 82.2, 54.4, and 31.7%, respectively, for the MH group (p=0.001); 1-, 3-, and 5-year disease-free survival rates were 75.0, 46.2, and 31.8%, respectively, for the TACE-MH group, and 69.6, 38.0, and 16.5%, respectively, for the MH group (p=0.002). CONCLUSIONS: Long-term outcomes of patients with preoperative TACE were improved and the pattern of the recurrences after surgery was altered. The patients with large centrally located HCC could benefit more from this neoadjuvant treatment, although there was some influence of preoperative TACE on postoperative complications.     

Is Preoperative Transarterial Chemoembolization Needed for a Resectable Hepatocellular Carcinoma?

Background Whether preoperative transarterial chemoembolization (TACE) has the therapeutic benefits in patients with resectable hepatocellular carcinoma (HCC) remains uncertain. Materials and methods We retrospectively investigated the influence of preoperative TACE on both disease-free survival and the pattern of recurrence after curative resection. From March 1998 to January 2005, a series of 273 patients who underwent curative resection for HCC were reviewed. Altogether, 120 patients underwent preoperative TACE, and 153 patients did not. We compared disease-free survival and the recurrence patterns between TACE and non-TACE groups, as well as between subgroups, stratified with regard to initial tumor size (≤3 cm, 3–5 cm, >5 cm) and pathologic tumor stage (stage I-II and stage III-IVa). We also compared disease-free survival and the pattern of recurrence among the three groups: complete necrosis, incomplete necrosis, non-TACE groups. Results The 1-, 3-, and 5-year disease-free survival rates were 76.0%, 57.7%, and 51.3%, respectively, in the TACE group and 70.9%, 53.8%, and 46.8%, respectively, in the non-TACE group. No significant difference was observed in disease-free survival or the pattern of recurrence between the TACE and non-TACE groups. Further analysis of disease-free survival and the pattern of recurrence between subgroups according to initial tumor size and tumor stage showed no significant differences. Complete necrosis of tumor was recognized in only 33 patients of the TACE group (p = 0.001). Among the three complete necrosis, incomplete necrosis, and non-TACE groups, no significant difference was observed in disease-free survival or the pattern of recurrence. Conclusions Preoperative TACE did not significantly improve the disease-free survival or the pattern of recurrence after curative resection of HCC. Even though this study is a retrospective analysis, preoperative TACE cannot be recommended as a routine procedure before hepatectomy for a resectable HCC.     

Is preoperative hepatic arterial chemoembolization safe and effective for hepatocellular carcinoma?

OBJECTIVE. The value of preoperative transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) has not been duly appreciated. The authors assessed the advantages and disadvantages of preoperative TACE by reviewing their experience with the procedure. METHODS. A total of 140 patients who underwent hepatectomy for HCC were entered into the study (105 received preoperative TACE and 35 did not). The authors investigated the reduction of tumor size and the complications after TACE, as well as the relationship between the interval from TACE to resection and the occurrence of complications. They compared postoperative morbidity and mortality between the TACE and non-TACE groups. They also compared survival and disease-free survival between the two groups, as well as between subgroups, defined by the extent of tumor necrosis achieved with TACE. RESULTS. A distinct reduction of tumor size was observed in approximately half of the TACE group. However, there were 68 appreciable complications of TACE in 56 patients (53.3%), and the interval between TACE and resection was significantly prolonged in the patients with complications. The postoperative morbidity and mortality rates of the TACE group were not different from those of the non-TACE group. Preoperative TACE did not improve the survival or disease-free survival of the whole patient group after hepatectomy. In addition, the survival and disease-free survival rates of the three TACE subgroups were not different from those of the non-TACE group. CONCLUSIONS. Preoperative TACE should only be performed to reduce tumor bulk in patients with HCC with borderline resectability. In such patients, increased tumor resectability appears to improve the survival rate. Preoperative TACE does not promote tumor recurrence.

Role of Preoperative Transcatheter Arterial Chemoembolization for Resectable Hepatocellular Carcinoma: Relation between Postoperative Course and the Pattern of Tumor Recurrence

The effects of preoperative transcatheter arterial chemoembolization (TACE) were retrospectively evaluated in patients with resectable hepatocellular carcinoma (HCC). A total of 227 patients who underwent hepatectomy for HCC were studied (146 underwent preoperative TACE and 81 did not). We compared operative outcome, mortality, and disease-free survival between TACE and non-TACE groups. We also compared the pattern of recurrence and postrecurrence survival between subgroups according to staging. Of the 227 patients, 105 with tumor stage I-II were assigned to group A (group A/TACE, n = 69; group A/non-TACE, n = 36), and the remaining 122 with tumor stage III-IV were assigned to group B (group B/TACE, n =77; group B/non-TACE, n =45). Complete necrosis was found to be more frequent in the TACE group (p < 0.01). Operating time, blood loss, and mortality did not differ between those who did and did not undergo preoperative TACE. TACE did not significantly improve disease-free survival within either the entire TACE group or group A/TACE. In contrast, in group B/TACE the disease-free survival rates were significantly higher than in group B/non-TACE. Furthermore, both extrahepatic metastasis and diffuse intrahepatic metastasis were significantly more frequent in group B/non-TACE than in group B/TACE. The preoperative TACE also improved the postrecurrence survival in group B. We speculate that preoperative TACE reduced tumor recurrence and that it might confer a survival advantage after surgery, particularly in patients with advanced HCC. In addition, it is expected that this procedure may improve the pattern of tumor recurrence when it does occur.     

Postoperative transhepatic arterial chemoembolization and portal vein chemotherapy for patients with hepatocellular carcinoma: a randomized study with 131 cases

OBJECTIVE: To explore the value of postoperative transarterial chemoembolization (TACE) and portal vein chemotherapy (PVC) in patients with hepatocellular carcinoma (HCC) in the prevention of recurrence, and to evaluate prognostic factors in a randomized study. METHOD: 131 patients with HCC were randomly divided into 3 groups: operation only (group A, n = 45); operation plus TACE (group B, n = 39), and operation plus TACE and PVC (group C, n = 47). Disease-free survival rates as well as prognostic factors were analyzed. RESULTS: Most of the side effects and complications related to the operation, catheters and local chemotherapy were liver decompensation (16.1%), catheter obstruction (12.9%), and nausea and loss of appetite (25.8%), respectively. The disease-free survival curves were significantly different between the 3 groups as estimated by the Kaplan-Meier method (p < 0.05). Group C had a significantly higher disease-free survival rate compared to group A (p < 0.05). But no statistical differences were found between groups A and B and groups B and C (both p > 0.05). Tumor number and treatment modalities were independent prognostic factors for HCC patients (p < 0.05). CONCLUSION: Postoperative TACE combined with PVC may benefit the survival of patients with HCC. In specialized medical centers, aggressive methods such as TACE and PVC should be attempted on HCC patients without contraindications.

Impact of pretransplantation transarterial chemoembolization on survival and recurrence after liver transplantation for hepatocellular carcinoma.

The actual impact of transarterial chemoembolization before liver transplantation (LT) for hepatocellular carcinoma (HCC) on patient survival and HCC recurrence is not known. Between 1985 and 1998, 479 patients with HCC in 14 French centers were evaluated for LT. Among these 479 patients, this case-control study included 100 patients who received transarterial chemoembolization before LT (TACE group) and 100 control patients who did not receive chemoembolization (no-TACE group). Patients and controls were matched for the pre-LT tumor characteristics, the period of transplantation, the time spent on the waiting list, and pre- and posttransplantation treatments. Kaplan-Meier estimates were calculated 5 years after LT and were compared with the log-rank test. The mean waiting time before LT was 4.2 +/- 3.2 months in the TACE group and 4.3 +/- 4.4 months in the no-TACE group. The median number of TACE procedures was 1 (range: 1-12). Demographic data, median alpha-fetoprotein level (21.6 ng/mL and 22.0 ng/mL, respectively), and pre- and post-LT morphologic characteristics of the tumors did not differ in the TACE and no-TACE groups. Overall 5-year survival was 59.4% with TACE and 59.3% without TACE (ns). Survival rates did not differ significantly between the two groups with respect to the time on the waiting list, the tumor diameter, or the type of TACE (selective or nonselective). In the TACE group, 30 patients had tumor necrosis > or =80% on the liver explant with a 5-year survival rate of 63.2%, compared with 54.2% among their matched controls (P = 0.9). In conclusion, with a mean waiting period of 4.2 months and 1 TACE procedure, pre-LT TACE does not influence post-LT overall survival and disease-free survival.
