Background:

Gastric cancer is a leading cause of cancer mortality worldwide, with increasing death rates despite available treatments.
Lymph node metastasis is a critical prognostic factor, highlighting the need for early diagnosis and effective screening.
Current diagnostic methods like endoscopy are limited by cost and accessibility, necessitating innovative approaches.

Purpose of the Study:

To review the significance and clinical applications of DNA microarray analysis in gastric cancer research.
To explore how gene expression profiling can define genetic characteristics of gastric tumors.
To assess the potential of microarray analysis in guiding more effective treatment decisions.

Main Methods:

Review of existing literature on DNA microarray analysis in gastric cancer.
Analysis of studies focusing on gene expression profiling and its correlation with prognosis and metastasis.
Examination of the role of microarray technology in identifying potential non-invasive biomarkers.

Main Results:

DNA microarray analysis enables simultaneous measurement of numerous gene expression levels.
Gene expression profiles derived from microarray data can be correlated with tumor prognosis and metastatic potential.
This technology aids in understanding the molecular mechanisms underlying gastric cancer proliferation and metastasis.

Conclusions:

DNA microarray analysis is a valuable tool for characterizing gastric cancer at a genetic level.
Its application can lead to improved diagnostic and prognostic capabilities, potentially enhancing patient survival rates.
Further research into microarray-based biomarkers could revolutionize gastric cancer screening and treatment strategies.
