Biomarkers in localized prostate cancer.

Biomarkers can improve prostate cancer diagnosis and treatment. Accuracy of prostate-specific antigen (PSA) for early diagnosis of prostate cancer is not satisfactory, as it is an organ- but not cancer-specific biomarker, and it can be improved by using models that incorporate PSA along with other test results, such as prostate cancer antigen 3, the molecular forms of PSA (proPSA, benign PSA and intact PSA), as well as kallikreins. Recent reports suggest that new tools may be provided by metabolomic studies as shown by preliminary data on sarcosine.

Urotensin II receptor on preoperative biopsy is associated with upstaging and upgrading in prostate cancer.

Aim: A higher Gleason score was associated with a lower tumor urotensin II receptor (UTII-R) expression in prostate cancer patients.

Methods: A retrospective review of formalin-fixed paraffin-embedded tumor tissue derived from those who had prostatectomy and matching biopsy specimens was conducted at six Institutions. UTII-R expression was evaluated on biopsy by immunohistochemistry.

Evaluation of the prognostic significance of perirenal fat invasion and tumor size in patients with pT1-pT3a localized renal cell carcinoma in a comprehensive multicenter study of the CORONA project. Can we improve prognostic discrimination for patients with stage pT3a tumors?

Background: The current TNM system for renal cell carcinoma (RCC) merges perirenal fat invasion (PFI) and renal vein invasion (RVI) as stage pT3a despite limited evidence concerning their prognostic equivalence. In addition, the prognostic value of PFI compared to pT1-pT2 tumors remains controversial.

Objective: To analyze the prognostic significance of PFI, RVI, and tumor size in pT1-pT3a RCC.

Results of a comparative study analyzing octogenarians with renal cell carcinoma in a competing risk analysis with patients in the seventh decade of life.

Objectives: To analyze clinicopathological features and survival of surgically treated patients with renal cell carcinoma (RCC) ≥ 80 years of age in comparison with patients between the ages of 60 and 70 years.

Materials And Methods: The data for 2,516 patients with a median follow-up of 57 months were retrieved from a multinational database (Collaborative Research on Renal Neoplasms Association [CORONA]), including data for 6,234 consecutive patients with RCC after radical or partial nephrectomy. Comparative analysis of clinicopathological features of 241 octogenarians (3.

Gender differences in clinicopathological features and survival in surgically treated patients with renal cell carcinoma: an analysis of the multicenter CORONA database.

Purpose: To investigate gender differences in clinicopathological features and to analyze the prognostic impact of gender in renal cell carcinoma (RCC) patients undergoing surgery.

Methods: A total of 6,234 patients (eleven centers; Europe and USA) treated by radical or partial nephrectomy were included in this retrospective study (median follow-up 59 months; IQR 30-106). Gender differences in clinicopathological parameters were assessed.
