Oxaliplatin and 5-fluorouracil hepatic infusion with lipiodolized chemoembolization in large hepatocellular carcinoma.

AIM: To investigate transarterial chemoembolization (TACE) with hepatic infusion of oxaliplatin and 5-fluorouracil and Lipiodol chemoembolization in large hepatocellular carcinoma (HCC). METHODS: In this retrospective study, 132 patients with unresectable HCCs larger than 10 cm were treated with hepatic infusion of oxaliplatin and 5-fluorouracil followed by Lipiodol chemoembolization. The primary endpoint was overall survival (OS). Sixteen-week disease-control rate, time to progression (TTP), and major complications were also studied. Univariate and multivariate analyses were performed to identify prognostic factors affecting OS and TTP. RESULTS: A total of 319 procedures were performed in the 132 patients. Eleven (8.3%) patients received radical resection following TACE treatment (median time to initial TACE 4.3 ± 2.3 mo). The median OS and TTP were 10.3 and 3.0 mo respectively, with a 50.0% 16-wk disease-control rate. Major complications were encountered in 6.0% (8/132) of patients following TACE and included serious jaundice in 1.5% (2/132) patients, aleukia in 1.5% (2/132), and hepatic failure in 3.0% (4/132). One patient died within one month due to serious hepatic failure and severe sepsis after receiving the second TACE. The risk factor associated with TTP was baseline alpha-fetoprotein level, and vascular invasion was an independent factor related to OS. CONCLUSION: Hepatic infusion of oxaliplatin and 5-fluorouracil followed by lipiodolized-chemoembolization is a safe and promising treatment for patients with HCCs larger than 10 cm in diameter.

[Evaluation of the efficacy and prognostic factors for colorectal liver metastases treated with transcatheter arterial chemoembolization].

OBJECTIVE: The aim of this study was to evaluate the therapeutic efficacy and to determine the prognostic factors of TACE in patients with colorectal liver metastases (CRLM). METHODS: The clinical data of 183 patients with unresectable CRLM treated with TACE from Jan. 2002 to Dec. 2008 were retrospectively reviewed. Log-rank method was used for univariate analysis and Cox proportional hazard model was used for multivariate analysis of the prognostic factors. RESULTS: The median survival time was 22 months, and the 0.5-, 1-, 2-, 3-, 5-year survival rates were 93.9%, 81.1%, 39.8%, 18.2%, and 3.9%, respectively. Multivariate analysis showed that tumor involved more than one lobe of the liver, and elevated CEA and CA19-9 levels were independent risk factors for the overall survival (P < 0.01). Females, more times of TACE, combination with regional therapy and received phase II resection were related with a good survival (P < 0.01) in CRLM patients after TACE treatment. CONCLUSIONS: Transcatheter arterial chemoembolization is an effective therapy for unresectable colorectal liver metastases. Patients with tumor spread more than one lobe of the liver, high CEA and CA19-9 levels are independent poor prognostic factors. Females, patients received more times of TACE, combined with regional therapy and received phase II resection may have a good survival.

[Transcatheter hepatic arterial chemoembolization on recurrent hepatocellular carcinoma after resection].

OBJECTIVE: To investigate the effect of transcatheter hepatic arterial chemoembolization (TACE) therapy on the survival and prognosis of recurrent hepatocellular carcinoma (HCC) after surgical resection. METHODS: The data of 130 surgically resected but recurrent HCC patients treated by TACE were reviewed retrospectively. The survival and influencing factors on the prognosis were analyzed. RESULTS: The overall 1-, 3-, 5-year survival rates of these 130 patients were 83.0%, 45.5% and 17.6% respectively (median survival time 2.4 years). Ninty-four of the series were treated with TACE alone, which gave the 1-, 3- year survival rates of 76.4% and 37.1%, respectively (median survival time 2.1 years). Thirty-six out of 130 patients treated with TACE plus percutaneous ethanol injection (PEI), the 1-, 3-year survival rates were 100.0% and 66.5% respectively with a median survival time (MST) of 3.5 years. The survival of TACE plus PEI group was significantly better, and the mortality risk was significantly lower than that of TACE alone group (P < 0.05). The mortality risk of those with > 5 cm diameter recurrent tumor or with distant metastasis was significantly higher than those with < or = 5 cm diameter tumor or without metastasis (P < 0.05). CONCLUSION: TACE combined with PEI may improve the survival of recurrent HCC patients.
