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

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

Conventional medications lack the efficacy to offer complete remission in IBD therapy,and usually associate with serious side effects. Recent studies indicated that nanoparticle-based nanotherapeutics may offer precise and safe alternative to conventional medications via enhanced targeting,sustained drug release,and decreased adverse effects. Here,we reviewed orally cell-specific nanotherapeutics developed in recent years. In addition,the various obstacles for oral drug delivery are also reviewed in this manuscript. Orally administrated cell-specific nanotherapeutics is expected to become a novel therapeutic approach for IBD treatment.展开更多
