Gastric Cancer Recurrence Patterns and Management Strategies
Summary
Gastric cancer remains a leading cause of cancer mortality globally, in part due to high rates of recurrence following curative resection. Recurrence patterns most often manifest as locoregional relapse, peritoneal dissemination or distant metastases, each reflecting distinct biological pathways and clinical implications. Locoregional recurrence typically results from residual microscopic disease in the gastric bed or regional lymph nodes, whereas peritoneal recurrence arises from tumour cell seeding within the abdominal cavity. Distant metastases commonly involve the liver, lungs and distant lymph nodes, signalling systemic spread. Risk factors influencing recurrence include tumour stage, depth of invasion, lymph node status and molecular features of the tumour microenvironment. Emerging evidence emphasises the role of host factors such as sarcopenia and myosteatosis in shaping postoperative outcomes, with muscle quality increasingly recognised as a prognostic determinant. Management strategies are tailored according to recurrence patterns, combining surveillance protocols, systemic therapies—including cytotoxic agents, targeted therapies and immunotherapies—and locoregional interventions such as radiotherapy or surgical re-resection in selected cases. Personalized surveillance algorithms seek to balance early detection of asymptomatic relapse with minimising unnecessary investigations. Advances in predictive modelling and biomarkers aim to refine risk stratification and inform adaptive follow-up schedules. Integrating clinico-pathological parameters with imaging and molecular analyses underpins a more proactive approach to recurrence management, enhancing the prospects for improved survival and quality of life.

Gastric Cancer Recurrence Patterns and Management Strategies publication trend
The graph below shows the total number of articles in gastric cancer recurrence patterns and management strategies across all publications each year (not limited to Nature Index journals).
Technical terms
Locoregional recurrence: Return of tumour in the original gastric bed or regional lymph nodes.
Distant metastasis: Spread of cancer cells to organs or tissues distant from the primary site, such as liver or lungs.
Peritoneal recurrence: Tumour dissemination within the peritoneal cavity, often presenting with ascites or peritoneal implants.
Hazard rate: Instantaneous risk of recurrence at a specific postoperative time point.
Nomogram: A graphical tool that integrates multiple prognostic variables to estimate individual outcomes.
Sarcopenia: Loss of skeletal muscle mass and function, associated with poorer postoperative outcomes.
Myosteatosis: Infiltration of fat into muscle tissue, affecting muscle quality and prognosis.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
