Digital image analysis of endoscopic ultrasonography is helpful in diagnosing gastric mesenchymal tumors

Background

Recent studies suggest that a combination of radiofrequency ablation (RFA) and transarterial chemoembolization (TACE) may have theoretical advantages over TACE alone for treatment of hepatocellular carcinoma (HCC). The purpose of this study was to evaluate the effectiveness and safety of radiofrequency ablation following first-line TACE treatment in the management of HCC beyond the Milan Criteria.

Methods

Forty-five patients who consecutively underwent RFA following first-line TACE treatment for HCC beyond the Milan criteria were enrolled in this study. RFA was performed within 1–2 months after TACE treatment in patients who had incomplete necrotic tumor nodules. Primary effectiveness, complications, survival rates, and prognostic factors were evaluated retrospectively.

Results

Complete ablation was achieved in 76.2% of the lesions according to 1-month follow-up computed tomography/magnetic resonance imaging evaluation. The mean follow-up period was 30.9 months (range 3–94 months). There were no major complications after RFA therapy. The median overall survival was 29 months (range 20–38 months), with 1-, 2-, and 3-year survival of 89%, 61%, and 43%, respectively. Multivariate analysis revealed that tumor diameter (P?=?0.045, hazard ratio [HR]?=?0.228, 95% confidence interval [CI]: 0.054-0.968) and pretreatment serum alpha-fetoprotein level (P?=?0.024, HR?=?2.239, 95% CI: 1.114-4.500) were independent predictors for long-term survival.

Conclusions

HCC beyond the Milan criteria can be completely and safely ablated by radiofrequency ablation following first-line TACE treatment with a low rate of complications and favorable survival outcome. Further assessment of the survival benefits of combination treatment for HCCs beyond the Milan Criteria is warranted.     

Radiofrequency ablation versus transarterial chemoembolization for unresectable solitary hepatocellular carcinomas sized 5–8 cm

Objectives

This retrospective review was conducted to compare the efficacy of radiofrequency ablation (RFA) with that of transarterial chemoembolization (TACE) in treating large (5–8 cm) unresectable solitary hepatocellular carcinomas (HCCs).

Methods

Patients with large unresectable solitary HCCs primarily treated by RFA or TACE were reviewed. The primary endpoint was overall survival. Secondary endpoints were tumour response, time to disease progression, and treatment-related morbidity and mortality.

Results

There were 15 patients in the RFA group. Of these, 12 achieved complete ablation, one had ablation site recurrence, and five developed complications. Median disease-free survival in this group was 13.0 months (range: 2.8–38.0 months). The TACE group included 26 patients, of whom four obtained a partial response, none achieved a complete response, and five developed complications. The median time to disease progression in this group was 8.0 months (range: 1.0–68.0 months). There were no hospital deaths in this series. Median survival was 39.8 months in the RFA group and 19.8 months in the TACE group (P = 0.257). Rates of 1-, 2- and 5-year survival were 93.3%, 86.2% and 20.9%, respectively, in the RFA group and 73.1%, 40.6% and 18.3%, respectively, in the TACE group.

Conclusions

Both RFA and TACE are feasible treatments for large unresectable solitary HCCs. Both modes show comparable rates of complications and longterm survival, but RFA achieves better initial tumour control and results in better short-term survival.

Treatment strategies for hepatocellular carcinoma in Japan

The main methods of treatment for hepatocellular carcinoma (HCC) in Japan are hepatic resection, radiofrequency ablation (RFA) and transcatheter arterial chemoembolization (TACE). Meticulous follow up is then undertaken to check for recurrence, which is treated using repeated RFA or TACE. Hepatic arterial infusion chemotherapy has been introduced as treatment for advanced HCC, and the molecular‐targeted drug sorafenib is also now available. Rigorous medical care using these treatment methods and early diagnosis mean that the prognosis for HCC in Japan is the best in the world. This paper reviews the treatment strategies for HCC in Japan.     

Outcome of transarterial chemoembolization in patients with inoperable hepatocellular carcinoma eligible for radiofrequency ablation

AIM: To evaluate the outcome of transarterial chemoembolization (TACE) in patients with unresectable hepatocellular carcinoma (HCC)<5 cm in diameter eligible for radiofrequency ablation (RFA). METHODS: The treatment-related mortality, morbidity, long-term survival, and prognostic factors of HCC patients who had TACE and fulfilled the present inclusion criteria for RFA were evaluated. RESULTS: Of the 748 patients treated with TACE between January 1990 and December 2002,114 patients were also eligible for RFA. The treatment-related mortality and morbidity were 1% and 19%, respectively. Survival at 1, 3, and 5 years was 80%, 43%, and 23%, respectively. Older age and a high albumin level were associated with a better survival, whereas a high a-fetoprotein level (AFP) and the size of the largest tumor >3 cm in diameter were adverse prognostic factors in multivariate analysis. CONCLUSION: The morbidity, mortality, and survival data after TACE for small HCCs eligible for RFA are comparable to those reported after RFA in the literature. Our data suggest the need for a randomized comparison of the two treatment modalities for small HCCs.     

Therapeutic radiological interventional procedures in hepatocellular carcinoma.

BACKGROUND: To improve the survival rate of patients with hepatocellular carcinoma (HCC) in whom surgery is not possible, various methods have been developed employing angiographic and percutaneous techniques. We analyzed our experience with various percutaneous therapeutic interventional techniques done for HCC in our center. METHODS: Sixty-one patients with inoperable HCC (mean age 48.9 [SD 13.8] y; 47 men) were treated between January 1997 and December 2000 by transcatheter arterial chemoembolization (TACE) alone (22), TACE with percutaneous alcohol injection (PEI) (20), transcatheter arterial embolization (TAE) with steel coils and gel foam for gastrointestinal bleed (7), percutaneous radiofrequency ablation (1), percutaneous preoperative right portal vein embolization (3) and percutaneous preoperative tumor embolization to reduce blood loss at surgery (8). RESULTS: In 42 patients treated by TACE and PEI and TACE alone, tumor necrosis was scored; over 50% necrosis was seen only after six and nine months in both treatment groups. The survival rates after six and nine months and the median survival were similar in the two groups. Of 7 cases treated with TAE with steel coils and gel foam, the gastrointestinal bleeding stopped in four; in the other three, bleeding did not stop completely although less transfusion was required. In the patient treated by radiofrequency ablation, follow-up contrast-enhanced CT did not show enhancing tumor mass. We noted left lobe enlargement after percutaneous preoperative right portal vein embolization, prior to right hepatectomy. CONCLUSION: In patients with HCC not amenable to surgical intervention, a variety of percutaneous therapeutic interventional techniques may be used.     

Survival rates according to the Cancer of the Liver Italian Program scores of 345 hepatocellular carcinoma patients after multimodality treatments during a 10-year period in a retrospective study

Background and Aim: The Cancer of the Liver Italian Program (CLIP) score has been demonstrated to have superior prognostic ability in hepatocellular carcinoma (HCC) patients worldwide, but there has never been sufficient assessment of the efficacy of treatment modalities according to the CLIP score. This retrospective cohort study of HCC patients was conducted to assess the efficacy of treatment modalities according to the CLIP score. Methods: We compared the efficacy of hepatic resection (HR) (n = 101), radiofrequency ablation with prior transcatheter arterial chemoembolization (RFA + TACE) (n = 115), percutaneous ethanol injection with prior TACE (PEI + TACE) (n = 43), and TACE (n = 86) as a primary treatment in terms of survival among 345 patients treated at Mie University Hospital between 1995 and 2004, according to CLIP score. Results: The overall survival rates in the RFA + TACE group were significantly higher in the patients with CLIP scores of 1, 2, and 3 or more (5‐year, 70.9%; 3‐year, 73.7%; and 3‐year, 100%, respectively), but they were not significantly different from the 5‐year survival rates of the HR group with a CLIP score of 0 (83.7%). Among the patients with a CLIP score of 0, a significantly higher disease‐free survival rate (5‐year: 33.7%) was obtained in the HR subgroup (n = 35) than in the RFA + TACE subgroup (n = 35), both of which were followed since 2000, but morbidity (21.8%) was highest in the HR group. Conclusion: RFA + TACE is concluded to be a safe treatment modality with better overall survival (5‐year, > 60%) in HCC patients regardless of their CLIP score.
