Background/Aim:
S100A8 is a chemoattractant known to be associated with metastatic niche formation. Herein, we evaluated the prognostic value of S100A8 in patients with clear cell renal cell carcinoma (CCRCC).
Materials And Methods:
A total of 152 CCRCC patients who have undergone nephrectomy were enrolled. The expression of S100A8 was assessed immunohistochemically using tissue microarray (TMA) blocks of CCRCC. Using statistical analysis, the relationship between S100A8 expression and clinicopathological factors was evaluated.
Results:
Among 152 TMA cores, 21 (6.9%) showed higher S100A8 expression. S100A8 expression was significantly increased in cores of patients with higher T stage (≥2, p<0.001) and higher Fuhrman nuclear grade (≥3, p<0.001). Multivariate analysis confirmed that high expression of S100A8 was significantly correlated to poor disease-free survival (hazard ratio, 2.601; 95% confidence interval (CI), 1.020-6.628; p-value=0.045).
Conclusion:
S100A8 expression may have a prognostic value in CCRCC reflecting TNM staging and Fuhrman nuclear grade.
