Abstract
Gastric cancer (GC) remains a leading cause of cancer mortality. While the extent of nodal involvement is a well-known prognostic factor, the specific entity of swollen lymph node metastasis (SLNM), bulky nodal tumor deposits detectable radiologically or pathologically, has received little attention in staging. Recent data from a study by Cui et al demonstrated that SLNM is an independent predictor of very poor survival in GC. Through robust data and rigorous propensity-matched analyses, SLNM emerged not merely as an anatomical finding but as an independent predictor of poor prognosis, even among patients undergoing curative resection. As precision oncology advances, the findings by Cui et al urge a fundamental rethinking of how SLNM is incorporated into clinical decision-making for GC management. In this editorial, we critically examine the prognostic significance of SLNM, challenge its omission from traditional staging frameworks, and advocate for its formal integration into preoperative risk stratification and treatment planning. Recognizing SLNM at diagnosis could unlock intensified neoadjuvant therapy strategies and optimize outcomes for a historically high-risk patient subgroup.
Core Tip: Swollen lymph node metastasis (SLNM), defined by bulky nodal tumor deposits (> 3 cm on imaging or multiple > 1.5 cm nodes) in gastric cancer, confers a dramatically worse outcome. In a large recent cohort, SLNM was independently associated with approximately 50% higher mortality risk. This editorial emphasizes SLNM’s under-recognized prognostic value. Formally incorporating SLNM into gastric cancer staging and treatment algorithms (for example, prioritizing neoadjuvant chemotherapy) may improve risk stratification. Recognizing SLNM as a biomarker can enhance precision oncology approaches by identifying patients for intensified multimodal therapy.
