Abstract:
It has been reported that the expression of tumor suppressor gene N-myc downstream-regulated gene 2 (NDRG2) was significantly reduced in human solid tumors, including esophageal squamous cell carcinoma (ESCC). This study aimed to explore whether the difference of NDRG2 expression exists in different stages of ESCC and provides a basis for the early diagnosis and prognosis of ESCC. Immunohistochemical staining was used to investigate the expression level of NDRG2 in samples from 91 patients with mild-to-moderate dysplasia, early ESCC, and advanced ESCC. The relationship between the expression of NDRG2 and clinicopathological characteristics of the patients was analyzed. The results showed that positive expression rates of NDRG2 in tissues adjacent to early ESCC (76.7%), or from mild-to-moderate dysplasia (74.1%), and early ESCC (83.3%) were significantly higher than in tissue from advanced ESCC (55.9%). The positive expression rate in advanced ESCC was significantly lower than in the other three tissue types (p < 0.05). There was a significant difference (p < 0.05) and correlation (Cramer's V = 0.351, p = 0.019, <0.05) between the expression of NDRG2 and the clinical stage in the 64 patients with ESCC. In conclusion, this study found that the expression of NDRG2 gradually decreased with the progression of esophageal lesions into advanced ESCC. This difference in positive expression rate was more obvious in male patients and patients under 60 years of age. Therefore, the detection of NDRG2 plays an important role in differentiating early ESCC from advanced ESCC.
Insights
The tumor suppressor gene NDRG2 expression decreases as esophageal squamous cell carcinoma (ESCC) progresses. Lower NDRG2 levels in advanced ESCC aid in early diagnosis and prognosis.
Area of Science:
- Oncology
- Molecular Biology
- Cancer Research
Background:
- N-myc downstream-regulated gene 2 (NDRG2) is a tumor suppressor gene.
- NDRG2 expression is reduced in various human solid tumors, including esophageal squamous cell carcinoma (ESCC).
Purpose of the Study:
- To investigate NDRG2 expression differences across various stages of ESCC.
- To establish a basis for early diagnosis and prognosis of ESCC through NDRG2 detection.
Main Methods:
- Immunohistochemical staining was employed to assess NDRG2 expression levels.
- NDRG2 expression was analyzed in 91 patient samples: mild-to-moderate dysplasia, early ESCC, and advanced ESCC.
- Correlation between NDRG2 expression and clinicopathological characteristics was examined.
Main Results:
- Positive NDRG2 expression rates were significantly higher in mild-to-moderate dysplasia (74.1%), adjacent to early ESCC (76.7%), and early ESCC (83.3%) compared to advanced ESCC (55.9%).
- A significant decrease in NDRG2 expression was observed with ESCC progression (p < 0.05).
- NDRG2 expression correlated significantly with clinical stage (Cramer's V = 0.351, p = 0.019).
Conclusions:
- NDRG2 expression gradually diminishes as esophageal lesions progress to advanced ESCC.
- NDRG2 detection is crucial for differentiating early ESCC from advanced stages.
- The observed differences in NDRG2 expression were more pronounced in male patients and those under 60.
