Efficacy and Safety of Atezolizumab plus Bevacizumab versus Sorafenib in Hepatocellular Carcinoma with Main Trunk and/or Contralateral Portal Vein Invasion in IMbrave150.

Introduction: Atezolizumab plus bevacizumab significantly improved overall survival (OS) and progression-free survival (PFS) versus sorafenib in patients with unresectable hepatocellular carcinoma (HCC) in IMbrave150. Efficacy and safety in patient subpopulations with Vp4 portal vein tumor thrombosis (PVTT) and other high-risk prognostic factors are reported.

Methods: IMbrave150 was a global, randomized (2:1), open-label, phase 3 study in systemic treatment-naive patients with unresectable HCC; OS and PFS were co-primary endpoints.

Diagnostic relevance of p53 and Rb status in neuroendocrine tumors G3 from different organs: an immunohistochemical study of 465 high-grade neuroendocrine neoplasms.

The double inactivation of TP53 and RB1 is considered typical of neuroendocrine carcinomas (NECs) but is assumed to be rare in high-grade neuroendocrine tumors (NETs). The immunohistochemical determination of the p53 and Rb status has therefore been proposed as a diagnostic tool. We studied this status in a large series of high-grade neuroendocrine neoplasms, from multiple origins, in order to (a) assess the patterns observed in the different histopathological categories, (b) compare them between the various anatomic sites, and (c) evaluate their possible diagnostic relevance.

Results of complete cytoreductive strategy in patients with peritoneal metastases of colorectal origin with or without extraperitoneal metastases: A bicentric analysis.

Background: Increased survival can be achieved in patients with colorectal cancer peritoneal metastases (CRPM) treated with cytoreductive surgery. The benefit of this strategy remains uncertain when CRPM are associated with extraperitoneal metastases (EPM). The aim of this study was to compare short- and long-term outcomes of patients treated with CRS for CRPM, with or without EPM.
