Current Primary Outcome Measures
 (submitted: January 20, 2015)
Disease-specific survival [ Time Frame: 5 years ]
Safety and Efficacy of active surveillance and delayed intervention for the SRM, measured by disease-free survival at 5-years.
Original Primary Outcome Measures Same as current
Change History
Current Secondary Outcome Measures
 (submitted: January 20, 2015)
  • Objective Safety and Tolerability of Percutaneous Renal Biopsy [ Time Frame: 5 years ]
    Measured by observed total (minor and major) complications compared to historical complication rates for this procedure.
  • Quality-of-life outcomes for patients undergoing AS versus definitive therapy. [ Time Frame: 5 years ]
    Measured by SF12 Questionnaire at enrollment, 6 and 12 months and annually thereafter.
  • To determine objective selection criteria for active surveillance. [ Time Frame: 5 years ]
    Demographic (i.e. age, sex, race), clinical (i.e. comorbidities, medications, family history) and imaging characteristics (i.e. tumor size, enhancement patterns, tumor complexity) will be used to determine patients most suitable for active surveillance.
Original Secondary Outcome Measures Same as current

Descriptive Information
Brief Title The Delayed Intervention and Surveillance for Small Renal Masses (DISSRM) Registry
Official Title The Delayed Intervention and Surveillance for Small Renal Masses (DISSRM) Registry
Brief Summary Retrospective studies indicate that active surveillance for clinically localized, small renal masses (cT1a, <=4cm) is safe. It is our hypothesis that active surveillance is safe and efficacious when compared prospectively to patients undergoing immediate intervention for their small renal mass.
Detailed Description All patients are offered active surveillance or immediate intervention, as applicable, prior to being offered consent for the DISSRM Registry. All patients are enrolled and followed prospectively. Surveillance patients are followed per protocol with serial imaging, blood work and quality of life questionnaires. Intervention patients are followed at the discretion of the attending surgeon with serial QOL appointments/questionnaires.
