Some studies suggest cholecystectomy and the cholelithiasic disease are frequently associated to some neoplasms of the digestive tract. Cholecystectomy, through the physiopathologic alterations it causes, seems to assume the role of factor of risk for the development of a gastric neoplasm. The authors reviewed their casuistry by analysing the percentages of subjects in whom the gastric neoplasm was associated to a previous cholecystectomy or a concomitant cholelithiasis. The data obtained do not support the hypothesis that cholecystectomy or the "lithogenicity of the biliary ducts" may be a factor of risk for gastric cancer.

Gastric cancer (GC), one of the tumours with the highest mortality worldwide, is not a homogeneous disease, showing different features according to location, macroscopic aspect, histotype and molecular alterations. Adenocarcinoma is the most frequent epithelial GC (95%), the remaining 5% comprising rare epithelial tumours with their peculiarities, behaviour and incidence <6 cases/100,000/year. Due to the low number of cases, many aspects must be elucidated in this context.

The sine oculis homeobox homolog (SIX) family, a group of transcription factors characterized by a conserved DNA-binding homology domain, plays a critical role in orchestrating embryonic development and organogenesis across various organisms, including humans. Comprising six distinct members, from to , each member contributes uniquely to the development and differentiation of diverse tissues and organs, underscoring the versatility of the SIX family. Dysregulation or mutations in genes have been implicated in a spectrum of developmental disorders, as well as in tumor initiation and progression, highlighting their pivotal role in maintaining normal developmental trajectories and cellular functions.

Objective: This study aims to investigate the correlation between the tumor-stroma ratio (TSR) and peritoneal metastasis (PM) in gastric cancer (GC) and constructs a diagnostic model based on preoperative examination data.
Methods: To determine the feasibility of obtaining TSR in GC patients through preoperative examinations, the consistency of TSR between endoscopic biopsy tissues and postoperative histopathological tissues was evaluated. Additionally, the correlation between TSR and PM in GC was analyzed using Gene Expression Omnibus (GEO) datasets.

AME Case Rep
December 2024
The PLA Center of Respiratory and Allergic Disease Diagnosing Management, General Hospital of Northern Theater Command, Shenyang, China.
Background: Patients with asthma exhibit a significantly heightened susceptibility to eosinophilic granulomatosis with polyangiitis (EGPA) when compared to the general population. Vigilance for EGPA manifestations is crucial, especially in cases where asthma remains poorly controlled despite high-dose corticosteroid therapy or when eosinophil counts exceed 5%. The diagnosis of EGPA can be complex due to the absence of definitive biomarkers, as indicated by the American College of Rheumatology (ACR)'s 1990 classification criteria.
