    • Study Type - Harm (RCT)Level of Evidence1b OBJECTIVES: To assess possible excess mortality associated with prostate biopsy among screening participants of the European Randomized Study of Screening for Prostate Cancer (ERSPC). SUBJECTS AND METHODS: From three centres in the ERSPC (Finland, The Netherlands and Sweden) 50194 screened men aged 50.2-78.4 years were prospectively followed. A cohort of 12959 first-time screening-positive men (i.e. with biopsy indication) was compared with another cohort of 37235 first-time screening-negative men. Overall mortality rates (i.e. other cause than prostate cancer mortality) were calculated and the 120-day and 1-year cumulative mortality were calculated by the Kaplan-Meier method, with a log-rank test for statistical significance. Incidence rate ratios (RR) and statistical significance were evaluated using Poisson regression analyses, adjusting for age, total PSA level, screening centre and whether a biopsy indication was present, or whether a biopsy was actually performed or not. RESULTS: There was no statistically significant difference in cumulative 120-day other cause mortality between the two groups of men: 0.24% (95% CI, 0.17-0.34) for screening-positive men vs 0.24% (95% CI, 0.20-0.30) for screening-negative men (P= 0.96). This implied no excess mortality for screening-positive men. Screening-positive men who were not biopsied (n= 1238) had a more than fourfold risk of other cause mortality during the first 120 days compared to screening-negative men: RR, 4.52 (95% CI, 2.63-7.74) (P < 0.001), adjusted for age, whereas men who were actually biopsied (n= 11721) had half the risk: RR, 0.41 (95% CI, 0.23-0.73) (P= 0.002), adjusted for age. Only 14/31 (45%) of the screening-positive men who died within 120 days were biopsied and none died as an obvious complication to the biopsy. CONCLUSIONS: Prostate biopsy is not associated with excess mortality and fatal complications appear to be very rare.

  • Cysteine-rich secretory protein 3 and β-microseminoprotein on prostate cancer needle biopsies do not have predictive value for subsequent prostatectomy outcome.
  • 2011

    • OBJECTIVES: • To investigate whether cysteine-rich secretory protein 3 (CRISP-3) and/or β-microseminoprotein (β-MSP) expression in diagnostic prostate needle biopsies have predictive value for prostate cancer (PC) on radical prostatecomy (RP). • To evaluate their potential clinical implementation in a preoperative setting. PATIENTS AND METHODS: • In total, 174 participants from the European Randomized Study of Screening for Prostate Cancer, Rotterdam section, treated by RP for PC were included in the present study. • CRISP-3 and β-MSP immunohistochemistry was performed on corresponding diagnostic needle biopsies. • Outcome was correlated with clinicopathological parameters (prostate-specific-antigen, PSA; number of positive biopsies; Gleason score, GS; pT-stage; surgical margins at RP) and significant PC at RP (pT3/4, or GS > 6, or tumour volume ≥0.5 mL) in the total cohort (n= 174) and in a subgroup with low-risk features at biopsy (PSA ≤ 10 ng/ml, cT ≤ 2, PSA density <0.20 ng/mL/g, GS < 7 and ≤2 positive biopsy cores; n= 87). RESULTS: • β-MSP and CRISP-3 expression in PC tissue was heterogeneous, with variable staining intensities occurring in the same tissue specimen. • High expression of β-MSP significantly correlated with GS < 7 at RP; it was not a predictor for significant PC at RP neither in the total group (n= 174; odds ratio, OR, 0.319; 95% confidence interval, CI, 0.060-1.695; P= 0.180), nor in the low-risk group (n= 87; OR, 0.227; 95% CI, 0.040-1.274; P= 0.092). • CRISP-3 expression was not related to clinicopathological parameters, and did not predict significant PC at RP in the total group (n= 174; OR, 1.056; 95% CI, 0.438-2.545; P= 0.904) or the low-risk group (n= 87; OR, 1.856; 95% CI, 0.626-5.506; P= 0.265). CONCLUSIONS: • High β-MSP expression correlated with low GS in subsequent RP specimens, supporting the view that β-MSP exerts a tumour-suppressive effect. • No significant prognostic value of β-MSP or CRISP-3 in prostate needle biopsies for significant PC at RP was found. • β-MSP or CRISP-3 do not have additional value in the therapeutic stratification of patients with PC.

  • Tumour markers in prostate cancer III: Biomarkers in urine
  • 2011
  • Ingår i: Acta Oncologica. - 1651-226X. ; 50, s. 85-89
  • Forskningsöversikt (refereegranskat)abstract
    • The serum PSA test still is the most important biomarker for the detection and follow-up of prostate cancer. PSA-based screening can reduce disease specific mortality but coinciding unnecessary testing and overdiagnosis warrant further research for more specific biomarkers. Numerous studies of both serum and urine-based prostate cancer biomarker candidates have been presented the last ten years. However, biomarkers for identifying the most aggressive subsets of this malignancy are still missing. Being non-invasive, urine-based tests might be suitable for both clinical and (mass) screening purposes, but also for prediction and to gain prognostic information. Protein-based, DNA-based and RNA-based urine biomarkers have been developed and tested. Protein markers in urine. Data on protein-based urine biomarkers (i.e. Annexin A3, matrix metalloproteinases and the urinary: serum PSA ratio) show up to now contradictory results and further studies are warranted to be able to assess their clinical value in which the cost aspect should not be overlooked. DNA markers in urine. Studies on DNA-based urine biomarkers focus on hypermethylation of gene panels with GSTP1 hypermethylation being the most promising individual marker. Larger prospective clinical studies of single markers and gene panels are however needed to validate their clinical utility. RNA markers in urine. RNA-based urine biomarkers are by far the most developed. The PCA3 test, the TMPRSS2-ERG fusion gene, transcript expression levels of GOLPH2, SPINK1 and their combination have been subject of many studies showing encouraging results. Conclusion. Up to now urine-based biomarkers represent a promising alternative or addition to serum-based biomarkers. Prospective studies in a multivariate setting, including larger sample sizes and avoiding attribution bias caused by preselection on the basis of serum PSA are however required.
