Treatment Outcomes for Gastric Cancer With Positive Peritoneal Lavage Cytology or Localized Peritoneal Metastasis

Importance In the era of modern systemic chemotherapy, the optimal treatment strategy for gastric cancer with positive peritoneal lavage cytology (CY1) and/or localized peritoneal metastasis (P1a) remains controversial. Objective To explore the optimal treatment strategy for pati...

Survival Results by the Prospectively Determined Clinical Staging for Locally Advanced Gastric Cancer: A Follow‐Up Study of JCOG1302A

ABSTRACT Background Long‐term overall survival (OS) of gastric cancer stratified by the prospectively determined clinical stage remains unclear. Methods This is an ancillary study of JCOG1302A, a prospective observational study that evaluated the accuracy of clinical diagnosis of...

Exploratory spatial transcriptomic analysis of compartment-specific recurrence-associated gene expression in gastric cancer

We hypothesized that the prognostic value of immune and stromal gene expression is spatially dependent—specifically, signals driving homeostasis in the superficial mucosa may differ functionally from those at the deep invasive front. We analyzed formalin-fixed paraffin-embedded s...
