A Molecular Urine Assay to Detect Recurrences During Surveillance of High-Risk Non-Muscle Invasive Bladder Cancer.

Background: High-risk non-muscle invasive bladder cancer (HR-NMIBC) patients require long-term surveillance with cystoscopies, cytology and upper tract imaging. Previously, we developed a genomic urine assay for surveillance of HR-NMIBC patients with high sensitivity and anticipatory value.

Objective: We aimed to validate the performance of the assay in an unselected prospectively collected cohort of HR-NMIBC patients under surveillance.

End-fire versus side-fire: a randomized controlled study of transrectal ultrasound guided biopsies for prostate cancer detection.

To compare prostate cancer detection rates between end-fire and side-fire ultrasound guided prostate biopsy techniques. A prospective randomized controlled trial was performed in patients who underwent prostate biopsy between 2009 and 2014. Patients were randomly assigned to the end-fire or side fire biopsy groups and underwent transrectal ultrasound guided prostate biopsy.

A Urine Based Genomic Assay to Triage Patients with Hematuria for Cystoscopy.

Purpose: Current clinical guidelines recommend cystoscopy in patients who present with hematuria to rule out a bladder tumor. We evaluated whether our previously developed urine assay was able to triage patients with hematuria for cystoscopy in a large prospective cohort.

Materials And Methods: A urine sample was collected before cystoscopy and mutation/methylation status of 6 genes was determined on cellular DNA.

Long-term follow-up after active surveillance or curative treatment: quality-of-life outcomes of men with low-risk prostate cancer.

Purpose: To compare long-term (4-10 years) quality of life (QoL) of men with low-risk prostate cancer (PCa) treated by different modalities and a reference group without PCa.

Methods: In this cross-sectional study, four groups were sent a one-time QoL-questionnaire; PCa patients (1) following the structured Prostate cancer Research International Active Surveillance protocol, (2) who underwent radical prostatectomy (RP) in the context of the European Randomized study of Screening for Prostate Cancer-section Rotterdam, (3) who underwent radiotherapy (RT) at an academic hospital in The Netherlands, and (4) an age-matched reference group of men without PCa. The QoL-questionnaire addressed prostate-specific health (EPIC), generic health (SF-12), and anxiety (STAI-6).

Cancer survivors' preference for follow-up care providers: a cross-sectional study from the population-based PROFILES-registry.

Background: The best practice for the organization of follow-up care in oncology is under debate, due to growing numbers of cancer survivors. Understanding survivors' preferences for follow-up care is elementary for designing patient-centred care. Based on data from prostate cancer and melanoma survivors, this study aims to identify: 1) preferences for follow-up care providers, for instance the medical specialist, the oncology nurse or the general practitioner; 2) characteristics associated with these preferences and 3) the preferred care provider to discuss cancer-related problems.

Short-term outcomes of the prospective multicentre 'Prostate Cancer Research International: Active Surveillance' study.

Objective: To evaluate the short-term outcomes of the prospective international Prostate Cancer Research International: Active Surveillance ('PRIAS') study (Dutch Trial Register NTR1718), as active surveillance (AS) for early prostate cancer might provide a partial solution to the current overtreatment dilemma in this disease.

Patients And Methods: The first 500 (of >950) participants with asymptomatic T1c/T2 prostate cancer, with a prostate-specific antigen (PSA) level of < or =10.0 ng/mL, a PSA density of <0.
