RÉSUMÉ

BACKGROUND/AIMS: We aimed to determine the association between the co-expression patterns of Notch1, Snail, and p53 proteins (NSP) and the postoperative prognosis of hepatocellular carcinoma (HCC). METHODS: The immunoblot data for molecular expression (147 HCC/corresponding non-HCC tissues and 15 dysplastic nodules) and the sequencing data for p53 mutations (110 HCCs) were obtained from our previous study. Data analyses were restricted to cases with HCC differentiation grade III (n=47), due to its high p53 mutation rate. RESULTS: Nineteen of the 47 patients (40.4%) -comprising 12 in the liver and 7 in distant organs-had relapsed at 1-2 years after surgery. There was no relationship between p53 mutation and postoperative recurrence in the grade III HCCs. Seven (87.5%) of the eight relapsed cases with Notch1, Snail, and p53 (wild) co-expression experienced recurrence only within the liver, and all tumors were smaller than 5 cm in diameter. Extrahepatic relapse occurred mostly in HCC patients with tumors larger than 5 cm in diameter, without any deviation in the NSP pattern. CONCLUSIONS: The results of this preliminary study suggest that the co-expression of Notch1, Snail, and p53 (wild) is not inferior to the patterns with p53 mutation as an indicator of postoperative recurrence of grade III HCC.

RÉSUMÉ

BACKGROUND/AIMS: Combination treatment consisting of hepatic arterial infusion chemotherapy with epirubicin and cisplatin (HAIC-EC) and systemic infusion of low-dose 5-fluorouracil (5-FU) are sometimes effective against advanced hepatocellular carcinoma (HCC). However, there is no effective treatment for advanced HCCs with arterioportal shunts (APS) or arteriovenous shunts (AVS). METHODS: We investigated a response and adverse events of a new combination protocol of repeated HAIC-EC and percutaneous intratumoral injection chemotherapy with a mixture of recombinant interferon-gamma (IFN-gamma) and 5-FU (PIC-IF) in patients with far-advanced HCCs with large APSs or AVSs. RESULTS: There was a complete response (CR) for the large vascular shunts in all three patients and for all tumor burdens in two patients. Significant side effects were flu-like symptoms (grade 2) and bone marrow suppression (grade 2 or 3) after each cycle, but these were well-tolerated. CONCLUSIONS: These results suggest that the combination of HAIC-EC and PIC-IF is a new and promising approach for advanced HCC accompanied by a large APS or AVS.
