Possible serum markers for renal transitional cell carcinoma: Report of a case with the review of literature (Olgu Sunumu)
MetadataShow full item record
Urothelial tumors of the upper urinary tract are relatively rare malignancies of urinary system. Despite the presence of specific serum parameters for prostate and testicular cancer, new markers need to be identified for renal and urothelial cancers. We report a case of huge renal pelvis tumor with high serum levels of carcinoembryonic antigen (CEA) and erythrocyte sedimentation rate (ESR). No distant metastasis was evident preoperatively. Radical nephroureterectomy was performed and the tumor was histologically diagnosed as high grade urothelial carcinoma of the renal pelvis. Surgical margins were negative and marked decrease in serum level of CEA and normalization of ESR, were noticed immediately after surgery.
