acid-phosphatase and Carcinoma--Renal-Cell

Diagnostic significance of estimation of the tartratresistent acid phosphatase (bone TRAP--5b) activity was studied for prognosis of occurrence of metastases in bones (MB) in patients with a renal-cell cancer (RCC). The risk of the MB occurrence was determined in patients after surgical treatment. A skeleton affection rate in patients, to whom zolendronic acid was prescribed, was trustworthy bigger, than such while conduction of treatment. So, application of bisphosphonates is recommended, in particular--zolendronic acid in dosage 4 mg every month under control of the bone TRAP--5b activity with objective of prophylaxis of the MB occurrence in patients, suffering RCC. But, we recommend for the MB diagnosis the method of determination of this marker activity as additional one while examining patients together with standard methods, including osteoscintigraphy, computer tomography.

The aim of the study was to determine the concentration of lipid peroxidation products, the activity of selected antioxidant and lysosomal enzymes, and protease inhibitor in patients with renal cell carcinoma who underwent radical nephrectomy. The studied group included 44 patients: 21 of them underwent open surgery, while 23 underwent laparoscopy. Blood samples were collected three times: before treatment and 12 hours and five days after nephrectomy. In blood of participants, the concentration of thiobarbituric acid reactive substances (TBARS), the activity of catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx), and the activity of acid phosphatase (AcP), arylsulfatase (ASA), cathepsin D (CTSD), and α 1-antitrypsin (AAT) were assayed. No statistically significant differences in investigated parameters were found between studied groups. Moreover, TBARS concentration and CAT, SOD, and GPx activity were not altered in the course of both types of surgery. Five days after both open and laparoscopic nephrectomy techniques, AAT activity was higher than its activity 12 hours after the procedure. The obtained results suggest that laparoscopy may be used for nephrectomy as effectively as open surgery without creating greater oxidative stress. Reduced period of convalescence at patients treated with laparoscopy may be due to less severe response of acute-phase proteins.

We assessed the diagnostic accuracy of bone markers in the serum of patients with renal cell carcinoma to detect bone metastases and evaluate the prognostic potential concerning renal cell carcinoma caused mortality.. The bone formation markers total and bone specific alkaline phosphatase, the bone resorption markers cross-linked N-terminal and tartrate-resistant acid phosphatase isoenzyme 5b, and the osteoclastogenesis markers osteoprotegerin and ligand of the receptor activator of nuclear factor-kappaB, were measured in the serum of 72 patients with renal cell carcinoma, including 28 with pN0M0, 8 with pN1M0 and 36 with M1, and in 32 female and 36 male controls by enzyme-linked immunosorbent assay techniques. Data were evaluated by receiver operating characteristics and survival analysis.. Bone specific alkaline phosphatase, tartrate-resistant acid phosphatase isoenzyme 5b and ligand of the receptor activator of nuclear factor-kappaB did not significantly differ between patients with renal cell carcinoma and controls. Compared with controls tartrate-resistant acid phosphatase isoenzyme 5b, cross-linked N-terminal and osteoprotegerin showed increased concentrations in patients with nonbone metastases but not in those with bone metastases. No bone turnover marker led to differentiation between patients with nonbone and bone metastases. Increased osteoprotegerin above the upper 95% cutoff limit, tumor stage and distant metastatic spread were associated with renal cell carcinoma related survival on Kaplan-Meier analyses. A multivariate Cox proportional hazards regression model revealed that these 3 variables were independent prognostic factors for cancer related death.. Bone turnover markers are hardly useful to diagnose bone metastases in patients with renal cell carcinoma. However, osteoprotegerin together with clinicopathological characteristics may be helpful as prognosticator of cancer specific death.

An autopsy case of adenocarcinoma of Skene's paraurethral gland co-incident with renal cell carcinoma is described. The adenocarcinoma showed distinct prostate specific antigen and prostate specific acid phosphatase pointing to the equivalence between the male prostate and Skene's paraurethral glands and ducts. Skene's gland are the homologue of the prostate in females and tumours arising from them are immunohistochemically similar to male prostate carcinoma.

Serum tissue polypeptide antigen (s-TPA) levels were determined in 124 patients having urogenital carcinomas, 74 with benign urological diseases and 55 normal subjects. We analyzed these results and determined the clinical significance of s-TPA as a tumor marker for urogenital carcinomas. S-TPA levels in the 55 normal subjects was 80 +/- 17 U/L (mean +/- S.D.). Since more than 95% of them showed an s-TPA level of below 110 U/L, this level was used as the cut-off value. The s-TPA level was 125 +/- 75 U/L for the 42 patients with benign prostatic hypertrophy, 138 +/- 60 U/L for the 15 patients with acute urinary tract infections (UTI) and 80 +/- 20 U/L in the 17 patients having other benign urological diseases. An elevated s-TPA level was clearly demonstrated in the case of acute UTI, which displayed a false positive result. The s-TPA level was 207 +/- 246 U/L for the 21 patients with bladder carcinoma, 197 +/- 52 U/L for the 5 patients with renal pelvic or ureteral carcinoma, 187 +/- 156 U/L for the 22 patients with renal cell carcinoma, 167 +/- 183 U/L for the 46 patients with prostatic carcinoma, and 95 +/- 28 U/L for the 8 patients with testicular carcinoma. In the 8 patients having bladder carcinoma, the elevation of s-TPA level seemed to be caused by the concomitant presence of acute UTI. The positive rate of s-TPA in various urogenital carcinomas was 100% for renal pelvic or ureteral carcinoma, 68% for renal cell carcinoma, 59% for bladder carcinoma, 52% for prostatic carcinoma and 13% for testicular carcinoma.(ABSTRACT TRUNCATED AT 250 WORDS)

Interest in the role of mononuclear phagocytes in glomerulonephritis (GN) and in defining markers of renal neoplasms led the authors to study alpha-naphthyl acetate/butyrate esterase (ANAE/ANBE), alkaline phosphatase (AlkP), acid phosphatase (AcP), 5'-nucleotidase (5'N), and ATPase (ATP) activity in paraformaldehyde-fixed, plastic-embedded renal tissue from patients with a variety of pathologic conditions. These conditions included GN, renal tumors, and transplant rejection. Enzymatic staining for ANAE, ANBE, AcP, AlkP, and ATP was generally confined to tubules and collecting ducts in normal kidney. Nine of 10 cases of renal carcinoma had weakly to strongly positive reactions with AlkP, AcP, and ANAE; 9 of 10 cases of Wilms' tumor showed weakly positive reactions with AcP and ANAE, particularly in tubular structures. Severely damaged kidney allografts showed surprising retention of normal histochemical features. In all cases 5'N stained both glomerular capillaries and interstitial vasculature; ATPase and AlkP stained interstitial vessels only. Plastic embedding provides superb preservation of both microscopic anatomy and enzymatic activity, which may allow utilization of enzyme histochemistry for diagnostic and research purposes.
