Adjuvant lipiodol I-131 after curative resection/ablation of hepatocellular carcinoma

HPB, Issue 6 2008
K. M. Ng
Abstract Aim. A total of 329 patients with hepatocellular carcinoma have been treated at our unit since 1990. Following the randomized controlled trial in Hong Kong by Lau et al. in 1999, patients have been offered adjuvant lipiodol I-131. The aim of this study was to determine the effectiveness of adjuvant lipiodol I-131, following potentially curative surgery with resection and/or ablation, on overall and disease-free survival rates. Material and methods. The prospectively updated hepatocellular carcinoma database was analysed retrospectively. A total of 34 patients were identified to have received adjuvant lipiodol I-131 post-curative treatment with surgical resection and/or ablation. Patient demographics, clinical, surgical, pathology, and survival data were collected and analysed. Results. Three patients received ablation alone, 24 resection, and 7 resection and ablation. Of the 34 patients treated, there were 2 possible cases of treatment-related fatality (pneumonitis and liver failure). Potential prognostic factors studied for effect on survival included age, gender, serum AFP concentration, Child-Pugh score, cirrhosis, tumor size, portal vein tumor thrombus, tumor rupture, and vascular and margin involvement. The median follow-up duration was 23.3 months. The overall median survival was 40.1 months, while the overall survival rates at 1, 2, 3, and 4 years were 87.1%, 71.7%, 60.7%, and 49.6%, respectively. Median duration to recurrence was 22.3 months. Conclusion. Administration of adjuvant lipiodol I-131 is associated with good overall survival. [source]

Major liver resections for hepatocellular carcinoma on cirrhosis: Early and long-term outcomes

LIVER TRANSPLANTATION, Issue S2 2004
Lorenzo Capussotti
Since the lack of donors, liver resections continue to be the treatment of choice for cirrhotic patients with good liver function and resectable hepatocellular carcinoma (HCC). Moreover, over the past 2 decades, an increasing number of major hepatic resections have been performed. The aim of this study is to evaluate short- and long-term outcomes of 55 cirrhotic patients undergoing major hepatic resection with particular attention to the survival of the patients with gross portal vein invasion or large size tumors. Twenty-two patients (40%) required intra- or post-operative blood transfusion. Medium tumor size was 66.6±29.2 mm; 7 patients had large size (> 10 cm) HCCs. A single node was present in 38 cases (69.1%). There was a gross portal vein tumor thrombus (PVTT) in 13 patients (23.6%). Resection was non-curative in 4 cases. In-hospital mortality and morbidity rates were 5.5% and 30.9%, respectively. The overall and disease-free survival rates were 36.2% and 42.8%, respectively. Overall 5-year survival rates of patients with large size tumors was 17.1%. Ten patients with a gross PVTT had an R0 resection with a 26.6% 5-year survival rate. In conclusion, major hepatic resections for HCC can be performed with low mortality and morbidity rates. HCCs with PVTT or greater than 10 cm in size have very limited options of treatment; the favorable long-term results of our study suggest that they should undergo surgery if a radical resection can be achieved.

Hepatocellular carcinoma with main portal vein tumor thrombus

CANCER, Issue 6 2009
Treatment with 3-dimensional conformal radiotherapy after portal vein stenting, transarterial chemoembolization
Abstract BACKGROUND: Hepatocellular carcinoma (HCC) with main portal vein tumor thrombus (MPVTT) is often associated with poor prognosis. We retrospectively assessed the effectiveness of percutaneous transhepatic portal vein stenting and transarterial chemoembolization (PTPVS-TACE) combined with or without 3-dimensional conformal radiotherapy (3-DCRT) for HCC with MPVTT. METHODS: Forty-five patients with HCC complicated by MPVTT were treated with PTPVS-TACE. Among them, 16 patients (group A) received 3-DCRT with 30-60Gy as daily 2Gy fractions. The remaining 29 patients (group B) received no radiotherapy. The tumor responses, complications, stent patency rates, and cumulative survival rates were evaluated, and the Kaplan-Meier method and log-rank test were used for survival analysis. RESULTS: No severe complications were associated with PTPVS-TACE and 3-DCRT. The objective response rate (CR and PR) was 35.6%. The 60-, 180-, and 360-day cumulative stent patency rates were 93.3%, 62.2%, and 34.6% in group A, and 58.6%, 21.7%, and 10.8% in group B, respectively, showing significant difference between the 2 groups (P < .01). The mean patency time was 475.20 ± 136.97 and 199.58 ± 61.40 days, respectively. The 60-, 180-, and 360-day cumulative survival rates were 93.8%, 81.3%, and 32.5%, respectively, for group A, 86.2%, 13.8%, and 6.9%, respectively, for group B. Significant statistical differences were detected between the 2 groups (P < .01). CONCLUSIONS: These findings suggest that sequential therapy by PTPVS-TACE-3-DCRT is possibly an effective treatment modality for HCC complicated by main portal vein tumor thrombus.
