Hereditary gastric cancer is a recently described clinical syndrome, associated with truncating mutation of the E-cadherin gene, named CDH1. It is characterized by autosomal dominant transmission, presentation at an early age, and with diffuse type of gastric adenocarcinoma. Clinical management of these patients is challenging and includes intense endoscopic surveillance or prophylactic gastrectomy, which is associated with short- and long-term morbidity. We report four patients submitted to a prophylactic gastrectomy performed in members of three families with hereditary gastric cancer in a tertiary referral center in Mexico City. These are the first Hispanic families with hereditary gastric cancer reported in the literature.

CTNNA1 codes α-1 catenin, a molecule that functions in intercellular adhesion in combination with E-cadherin (coded by CDH1). A germline pathogenic variant (GPV) of CTNNA1 increases the risk of hereditary diffuse gastric cancer (HDGC); however, this GPV has not been reported in Japan. A 35-year-old Japanese man with an advanced gastric cancer underwent comprehensive genome profiling (CGP), which led to the detection of a CTNNA1 GPV (p.

Objective: The effects of sex hormones remain largely unexplored in pheochromocytomas and paragangliomas (PPGLs) and gastroenteropancreatic neuroendocrine tumors (GEP-NETs).
Methods: We evaluated the effects of estradiol, progesterone, Dehydroepiandrosterone sulfate (DHEAS), and testosterone on human patient-derived PPGL/GEP-NET primary culture cell viability (n = 38/n = 12), performed next-generation sequencing and immunohistochemical hormone receptor analysis in patient-derived PPGL tumor tissues (n = 36).
Results: In PPGLs, estradiol and progesterone (1 µm) demonstrated overall significant antitumor effects with the strongest efficacy in PPGLs with NF1 (cluster 2) pathogenic variants.

Background: Understanding the heterogeneity of a population at risk is an important step in the early detection of gastric cancer. This study aimed to cluster demographic, hematologic, and biochemical markers of gastric cancer in a heterogeneous sample of patients.
Methods: Data of 695 adult patients (50.

Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease. About 10% of affected individuals have an inherited component. Deleterious germline variants increase the lifetime risk for PDAC and are often associated with an elevated risk for extra-pancreatic malignancies.
