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.

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.

Eligibility Criteria

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

• 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)
• If pathology report shows multiple subtypes in same tumor, as long as the majority of tumor is ccRCC (>50%), participant can be included

Exclusion Criteria

• TNM-stage T(any) N(any) M1 according to AJCC, i.e. metastatic disease at diagnosis
• Absence of preoperative chest imaging (chest CT) within 60 days prior to primary surgery
• Previous history of curatively treated for other cancers, still not deemed fully cured and participant still under surveillance for said cancer
• Participants offered active surveillance for RCC instead of curative intent surgery
• Participants offered any type of thermal ablation treatment instead of surgery, i.e. LP cannot be assessed

• Participants with AJCC cN0 status at preoperative imaging in whom a clinically suspicious regional lymph-node metastases (enlarged lymph node(s)) is noted during primary surgery, but who subsequently do not undergo any lymph node dissection. (Note: participants with cN0 status at pre-operative imaging and no clinical signs of regional lymph node metastases during primary surgery can still be included irrespective of lymph node dissection having been performed, i.e. being pN0 or pN1 if it is performed or pNx if it is not performed)
• Participants with AJCC cN1 status at pre-operative imaging in which lymph node dissection is not performed (i.e. pNx).
• Elected for any adjuvant therapy (i.e. systemic therapy) outside or within any clinical study
• Non-clear cell RCC histology or benign tumor (i.e. oncocytoma and angiomyolipoma, which are the most common benign types, but also any other rare types of benign renal tumors) after pathological analysis
• Any hereditary form of RCC (e.g. Von Hippel-Lindau, Birt-Hogg-Dubé, Hereditary Papillary RCC)
• RCC with pure sarcomatoid differentiation, also called sarcoma of the kidney
• Previous history of curatively treated for RCC with a suspected de novo RCC in the remaining kidney tissue
• Prior or current use of instillation therapy with hyaluronic acid and/or chondroitin sulfate (HA-CS).
• Use of heparin, including low molecular weight heparin (e.g. Enoxaparin, Dalteparin, Tinzaparin) for concurrent disease in need of blood dilution (e.g. ongoing deep vein thrombosis or lung emboli). Note: use of of heparin for thrombus prophylaxis in conjunction with primary surgery or postoperatively ≤4 weeks will be allowed.
• Patients who were not radically operated during primary surgery with the exception of histological positive surgical margin in participants who have undergone partial nephrectomy.

• Minimum Eligible Age: 18 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
