Brief Summary:
AUR87A is an observational prospective multicenter diagnostics test cohort study for detection of renal cell carcinoma recurrence as determined by the reference standard, which is imaging using computed tomography (CT) of the chest and abdomen at defined intervals after primary surgery.

Condition or disease Intervention/treatment
Clear Cell Renal Cell Carcinoma Diagnostic Test: GAG score

Detailed Description:

Non-metastatic clear cell renal cell carcinoma (ccRCC) recur in ~20% of cases within 5 years after radical surgery. Current postoperative follow-up protocols, being schematic and at best based on risk of recurrence scores, are sub-optimal for early detection of recurrences which could potentially be available for curative management. Blood and urine collected glycosaminoglycans (GAGs) are promising novel class of biomarkers from which a new diagnostic test based on so called GAG scores has been developed. GAG scores have accurately distinguished localized/locally-advanced and advanced RCC from healthy subjects.

AUR87A features an adaptive design. The primary endpoint analysis is conducted when 30 events (i.e. recurrences) are reached - expected at 140 patients with a minimum follow-up of 12 months (cohort 1). An interim analysis at 15 events is conducted to verify whether the sensitivity and specificity estimates are in line with the study assumptions. In case of futility, the GAG scores formulations and/or cut-offs are optimized based on data from cohort 1. The primary endpoints are then validated on a second independent cohort, powered depending on the results from cohort 1. This second cohort is estimated in 140 patients (cohort 2). In case of non-futility, cohort 2 may be used as external validation.

AUR87A will prospectively enroll an estimated 280 non-metastatic ccRCC patients curatively treated with surgery (partial or radical nephrectomy). Patients are followed-up longitudinally using GAG scores in blood and urine every 3 months after surgery, alongside the current standard follow-up protocol, i.e. imaging, as reference standard.

The hypothesis of AUR87A is that postoperative increase of the GAG scores, so called "GAG recurrence ", can predict or detect recurrence at an earlier time-point compared to the reference standard, referred to as "radiological recurrence", and thereby improve the clinical utility of current follow-up protocols.

Criteria

Inclusion Criteria:

Pre-screening inclusion criteria

  • Size of primary tumor >4cm (>cT1a) in greatest dimension on pre-operative abdominal CT-scan
  • Size of primary tumor ≤4cm is allowed if pre-operative abdominal CT-scan shows suspected RCCs with radiological sign of venous tumor thrombus (renal vein or caval).
  • Pre-operative CT-scan of chest and abdomen show no signs of metastatic disease
  • Localized and biopsy proven clear cell RCC (ccRCC) under active surveillance which at timepoint of study recruitment, opted for surgery because of growth rate of primary tumor to a size > 4cm
  • Elected for curative intent surgery for RCC

Final screening inclusion criteria

  • Any gender being 18 years or older at timepoint of final inclusion
  • In postoperative pathology report shown to be ccRCC subtype according to 8th Edition of the American Joint Committee on Cancer (AJCC)
  • Leibovich points (LP) ≥5 according to Leibovich score system (2003)
