Increased KIF21B expression is a potential prognostic biomarker in hepatocellular carcinoma.

Background: The kinesin superfamily protein member KIF21B plays an important role in regulating mitotic progression; however, the function and mechanisms of KIF21B in cancer, particularly in hepatocellular carcinoma (HCC), are unknown.

Aim: To explore the role of KIF21B in hepatocellular carcinoma and its effect on prognosis after hepatectomy.

Methods: First, data on the differential expression of KIF21B in patients with HCC from The Cancer Genome Atlas database was analyzed.

Primary intestinal extranodal natural killer/T-cell lymphoma, nasal type: A case report.

Background: Primary intestinal extranodal natural killer/T-cell lymphoma, nasal type (PI-ENKTCL) is a rare non-Hodgkin's lymphoma (NHL) subtype, and its prognosis is extremely poor. Clinical characteristics of the disease are not obvious and easily misdiagnosed. In this case report, we describe a patient with PI-ENKTCL who presented with intermittent hematochezia.
