Renal tumor with alpha B crystallin expression.
|
| Abstract |
In human, proximal convoluted tubules and thin limbs of Henle show expression of αB crystallin. Renal cell carcinoma also showed expression of αB crystallin in previous reports. We aimed to study the association between αB crystallin expression and renal cell carcinoma and urothelial carcinoma. Furthermore, we also investigated αB crystallin expression depending on the subtype of renal cell carcinoma and examined the relationship between αB crystallin expression and survival in patients with renal cell carcinoma. In our study, αB crystallin expression was different according to the type of tumor. A greater proportion of the clear cell type (52/77, 67.5%) and papillary type (4/4, 100%) showed reactivity compared to the chromophobe type (0/10, 0%). In the present study, a significantly greater number of renal cell carcinomas showed strong expression of αB crystallin (56/91, 61.5%) compared to urothelial carcinoma (P=7.967e-07). Therefore, αB crystallin might be a significant marker of renal cell carcinoma and might help to determine the type of renal tumor in cases of poorly differentiated kidney lesions and metastatic lesions. αB crystallin expression was not related to overall survival in univariate and multivariate models. In our study, alpha B crystallin could not be considered a prognostic marker of renal cell carcinoma.
