Meta analysis of radiofrequency ablation versus surgical resection in small and large nodule of hepatocellular carcinoma.

Introduction: Although studies have indicated comparable outcomes between RFA and surgical resection in early HCC, there is still unclear evidence of benefit in larger tumor sizes. This study aimed to assess the efficacy and safety of RFA versus surgical resection in HCC patients, considering nodule size with a cutoff at 3 cm.

Methods: A comprehensive search of multiple databases was conducted.

Transarterial embolization with bleomycin-lipiodol emulsion: a successful minimal invasive approach for giant liver hemangioma.

Hemangiomas are most common benign liver tumor. Most patients have an excellent prognosis because of the small size and benign nature of tumor. On some occasions, giant liver hemangioma may cause symptoms and significant challenges due to its complication.

Does immune checkpoint inhibitor increase the risks of poor outcomes in COVID-19-infected cancer patients? A systematic review and meta-analysis.

Background: The association between immune checkpoint inhibitor (ICI) and outcomes of cancer patients with coronavirus disease 2019 (COVID-19) infection has yet to be systematically evaluated. This meta-analysis aims to investigate the effects of ICI treatment on COVID-19 prognosis, including mortality, severity, and any other prognosis-related outcomes.

Methods: Eligible studies published up to 27 February 2021 were included and assessed for risk of bias using the Quality in Prognosis Studies tool.
