Abstract
CD147 is highly expressed in hepatocellular carcinoma (HCC) and associated with the invasion and metastasis of HCC. The efficacy of I131 -metuximab (I131 -mab), a newly developed agent that targets CD147, as a radio-immunotherapy for local HCC, has been validated in clinical practice. However, the synergistic anticancer activity and molecular mechanism of different conjugated components within I131 -mab remain unclear. In this study, the cytological experiments proved that I131 -mab inhibited the proliferation and invasion of HCC cells. Mechanically, this inhibition effect was mainly mediated by the antibody component part of I131 -mab, which could reverse the epithelial-mesenchymal transition of HCC cells partially by suppressing the phosphorylation of VEGFR-2. The inhibitory effect of I131 on HCC cell proliferation and invasion is limited, whereas, when combined with metuximab, I131 significantly enhanced the sensitivity of HCC cells to CD147-mab and consequently reinforced the anticancer effects of CD147-mab, suggesting that the two components of I131 -mab exerted synergistic anti-HCC capability. Furthermore, the experiments using SMMC-7721 human HCC xenografts in athymic nude mice showed that I131 -mab and CD147-mab significantly inhibited the growth of xenograft tumors and that I131 -mab was more effective than CD147-mab. In conclusion, our results elucidated the mechanism underlying the anti-HCC effects of I131 -mab and provided a theoretical foundation for the clinical application of I131 -mab.

Patterns and challenges of treatment sequencing in patients with hepatocellular carcinoma: Experience from a German referral center. J Gastroenterol Hepatol 2017; 32:1730-1738.

Abstract
BACKGROUND AND AIM Hepatocellular carcinoma (HCC) is one of the most prevalent and lethal cancers. Several local and systemic therapies are available for patients with HCC depending on the stage of the disease. In clinical practice, treatment decision-making, and sequencing may be very heterogeneous. METHODS In this study, we retrospectively analyzed treatment algorithms in 2101 patients with HCC treated from 2000 to 2015 at Hannover Medical School, Germany. RESULTS Transarterial chemoembolization was the most common initial treatment (n = 545; 25.9%), followed by resection (n = 435, 20.7%), local-ablative procedures (n = 283, 13.5%), systemic therapies (n = 275, 13.1%), and liver transplantation (n = 52; 2.5%). Most patients were treated only once (n = 960; 59.6%). A total of 433 (26.9%) and 160 (9.9%) patients received a second line and third line treatment after recurrent or progressive disease. Patients with more than one treatment line were diagnosed at significantly earlier disease stages (P < 0.001). Using binary logistic regression, AFP ≤ 200 μg/L, albumin > 36 g/L, and small tumor size (≤50 mm) were identified as predictors of achieving more than one treatment line. Subsequent treatment stage migration to a therapy suggested for the next advanced stage occurred only in 56.9%, whereas 43.1% received treatments suggested for earlier disease stages. Only 16% of all treated patients received systemic therapy in the salvage setting. CONCLUSION Most patients were treated only once, and only a minority of patients received systemic treatment. The high dropout rate for subsequent therapies needs to be considered within therapy decision-making. There is an urgent need for prospective studies to define the best time point when to switch patients from local to systemic therapies.
