Effect of immune checkpoint inhibitors in patients with gastric hepatoid adenocarcinoma: a case report and literature review.

ABSTRACT: Gastric hepatoid adenocarcinoma (GHAC) is a highly aggressive histological subtype of gastric cancer (GC) with similar tissue morphology to hepatocellular carcinoma. GHAC frequently produces alpha-fetoprotein (AFP) and has a poor prognosis; however, standardized treatment remains elusive. We report a male patient in his early 60s with GHAC who received immunotherapy, and the curative effect was evaluated. He was admitted because of progressive fatigue and dizziness for 2 months. He had experienced spontaneous epigastric pain with muscular defense of the epigastrium and accompanying tenderness 1 year earlier and underwent radical gastrectomy. Immunohistochemistry showed that hepatocyte-specific marker (Hep) was highly-expressed, indicating probable GHAC. Additionally, imaging suggested GC r
