Extranodal Extension of Nodal Metastases Is a Poor Prognostic Indicator in Gastric Cancer: a Systematic Review and Meta-analysis.
2016
Introduction: The extranodal extension (ENE) of nodal metastases (the extension of neoplastic cells through the nodal capsule into the perinodal soft tissue) is a histological feature that has been considered a prognostic factor in several cancers, but the role in gastric cancer was not yet investigated. We aimed to investigate the prognostic role of ENE in patients affected by gastric cancer through a systematic review and meta-analysis. Material and Methods: Two independent authors searched major databases until 09/30/2015 to identify studies providing data on gastric cancer patients’ prognostic parameters and comparing patients with ENE (ENE+) vs intra-nodal extension (ENE−). The data we…

Undifferentiated carcinoma of the pancreas with osteoclast-like giant cells (UCOGC) is currently considered a morphologically and clinically distinct variant of pancreatic ductal adenocarcinoma (PDAC). In this study, we report clinical and pathological features of a series of 22 UCOGCs, including the whole exome sequencing of eight UCOGCs. We observed that 60% of the UCOGCs contained a well-defined epithelial component and that patients with pure UCOGC had a significantly better prognosis than did those with an UCOGC with an associated epithelial neoplasm. The genetic alterations in UCOGC are strikingly similar to those known to drive conventional PDAC, including activating mutations in the…
