We conducted a systematic review and meta-analysis to assess the evidence available on the long-term outcomes of cHCC-CC patients after either hepatectomy or liver transplantation(LT). Data Sources: Relevant studies published between January 2000 and January 2018 were identified by searching Pub Med and Embase and reviewed systematically. Data were pooled using a random-effects model. Results: A total of 42 observational studies involving 1691 patients(1390 for partial hepatectomy and 301 for LT) were included in the analysis. The median tumor recurrence and 5-year overall survival(OS) rates were 65%(range 38%–100%) and 29%(range 0–63%) after hepatectomy versus 54%(range 14%–93%) and 41%(range 16%–73%) after LT, respectively. Meta-analysis found no significant difference in OS and tumor recurrence between LT and hepatectomy groups. Conclusion: Hepatectomy rather than LT should be considered as the prior treatment option for cHCC-CC.展开更多

METHODS:Eligible trials were identified from Medline, Embase,Ovid,and the Cochrane database.The data were analyzed with fixed-effects or random-effects models using Review Manager version 5.0. RESULTS:Thirteen nonrandomized studies with a total of 1431 participants were suitable for meta-analysis. There was no difference in overall morbidity and severe complications between the Bev+group and Bev-group (43.3%vs 36.8%,P=0.06;17.1%vs 11.4%,P=0.07,respectively).Bev-related complications including wound and thromboembolic/bleeding events were also similar in the Bev+and Bev-groups(14.4%vs 8.1%, P=0.21;4.1%vs 3.8%,P=0.98,respectively).The incidence and severity of sinusoidal dilation were lower in patients treated with Bev than in patients treated without Bev(43.3%vs 63.7%,P<0.001;16.8%vs 46.5%,P<0.00,respectively). CONCLUSION:Bev can be safely administered before hepatic resection in patients with CLM,and has a protective effect against hepatic injury in patients treated with oxaliplatin chemotherapy.展开更多

Search termswere “hepatic angiosarcoma” and “liver angiosarcoma”. Additional articles were retrieved through manualsearch of bibliographies of the relevant articles. Pooled individual data concerning the prognosis followingvarious therapeutic modalities were analyzed.展开更多
