Low ETV1 mRNA expression is associated with recurrence in gastrointestinal stromal tumors.

Although the majority of gastrointestinal stromal tumors (GISTs) possess KIT mutations that induce constitutive signal transduction, the clinical outcomes are variable. The ETS translocation variant 1 (ETV1) gene encodes a transcription factor that is reported to cooperate with KIT in GISTs. However, the clinical role of ETV1 is largely unknown.

[Gastric tuberculosis in an elderly patient:a case report].

A woman in her 70s presented to our hospital with epigastric pain, back pain, and weight loss. Esophagogastroduodenoscopy was performed, and numerous protuberances, which were suspected to be submucosal tumors, were found at the gastric corpus. The patient was diagnosed with gastric tuberculosis based on the biopsy results of these protuberances.
