Physicians must consider multiple factors when determining the most appropriate preoperative imaging strategy for gastric cancer. Health care resources are not unlimited, and the use of multiple expensive imaging techniques that do not alter treatment decisions is not recommended. With this in mind, EGD and CT scan alone should form the basis for preoperative evaluation, with further imaging considered only in selected cases. Based on the reviewed literature, we do not recommend routine surveillance imaging after curative surgery for gastric cancer. We agree with current NCCN guidelines that recommend history and physical examination every 4 to 6 months for 3 years, followed by yearly examinations. Imaging studies and endoscopy should be selectively performed in symptomatic patients.

Universidade de São Paulo, Faculdade de Medicina, Hospital das Clínicas, Department of Gastroenterology - São Paulo (SP), Brazil.
Background: The COVID-19 pandemic has overloaded healthcare systems worldwide. Other diseases, such as neoplasms, including gastric cancer, remained prevalent and had their treatment compromised.
Aims: The aim of this study was to evaluate the impact of the COVID-19 pandemic on the treatment of gastric cancer and adherence to the recommended preoperative COVID-19 screening protocol.

The aim is to describe the sociodemographic and clinical-epidemiological profile of hospital cases of gastric cancer and to analyze factors associated with the Time-to-Treatment in Brazil. Exploratory study of sociodemographic and clinical-epidemiological characteristics of cases of gastric cancer. Time-to-Treatment were continuously estimated and then categorized into ≤ 60/> 60 days to estimate prevalence.

Purpose: Trophoblast cell-surface antigen 2 (Trop2) is overexpressed in various solid tumors and contributes to tumor progression, while its expression remains low in normal tissues. Trop2-targeting antibody-drug conjugate (ADC), sacituzumab govitecan-hziy (Trodelvy), has shown efficacy in targeting this antigen. Leveraging the enhanced specificity of ADCs, we conducted the first immunoPET imaging study of Trop2 expression in gastric cancer (GC) and triple-negative breast cancer (TNBC) models using Zr-labeled Trodelvy ([Zr]Zr-DFO-Trodelvy).

Background: Gastric cancer poses a major diagnostic and therapeutic challenge. Improved visualization of tumor margins and lymph node metastases with tumor-specific fluorescent markers could improve outcomes.
Methods: To establish orthotopic models of gastric cancer, one million cells of the human gastric cancer cell line, MKN45, were suspended in 50 μl of equal parts PBS and Matrigel and injected into the nude mouse stomach with a 29-gauge needle.
