Abstract:
Peritoneal metastases occur in 55-60% of patients with gastric cancer (GC) and are associated with a 2% 5-year overall survival rate. There are limited treatment options for these patients, and no targeted therapy or immunotherapy is available. Rational therapeutic targets remain to be found. In this review, we present the published literature and our own recent experience in molecular biology to identify important molecules and signaling pathways as well as cellular immunity involved in the peritoneal metastasis of GC. We also suggest potential novel strategies for improving the outcomes of GC patients with peritoneal metastasis.
Insights
Peritoneal metastasis in gastric cancer (GC) is common and deadly, with no targeted treatments. This review identifies key molecular and immune factors, suggesting new therapeutic strategies for better patient outcomes.
Area of Science:
- Oncology
- Molecular Biology
- Immunology
Background:
- Peritoneal metastases are prevalent in gastric cancer (GC), affecting 55-60% of patients.
- This condition is linked to a poor 5-year survival rate of only 2%.
- Current treatment options for GC peritoneal metastasis are limited, lacking targeted therapies or immunotherapies.
Purpose of the Study:
- To review existing literature and recent molecular biology findings on GC peritoneal metastasis.
- To identify critical molecules, signaling pathways, and cellular immunity involved in GC peritoneal metastasis.
- To propose novel therapeutic strategies for improving outcomes in GC patients with peritoneal metastasis.
Main Methods:
- Comprehensive literature review of published studies.
- Analysis of recent molecular biology research and experimental data.
- Synthesis of findings related to molecular targets and cellular immune responses.
Main Results:
- Identification of specific molecular targets and signaling pathways implicated in GC peritoneal metastasis.
- Elucidation of the role of cellular immunity in the peritoneal microenvironment of GC.
- Highlighting unmet needs in current therapeutic approaches.
Conclusions:
- Understanding the molecular and immunological landscape is crucial for developing effective treatments.
- Novel strategies targeting identified pathways and immune components hold promise for improving survival.
- Further research is needed to translate these findings into clinical applications for gastric cancer peritoneal metastasis.
