Spots Global Cancer Trial Database for KIDNEY-PAGER: Analysis of Circulating Tumor DNA as a Biomarker in Renal Cancer - an Observational Trial

Study Description

Brief Summary: The overall aim of this observational study is to confirm that circulating tumor DNA (ctDNA) detected in plasma and or urine after intended curative treatment for renal cell carcinoma (RCC) can be applied in clinical practice as a marker of subclinical residual disease and risk of recurrence.

Detailed Description: OBJECTIVES The overall objective of the study is to confirm that circulating tumor DNA (ctDNA) detected in plasma and or urine after intended curative treatment for RCC can be applied in clinical practice as a marker of subclinical residual disease and risk of recurrence. 1.1 Primary objectives 1. To confirm that patients with high risk of recurrence can be identified with ctDNA profiling performed immediately after nephrectomy. Specifically, we aim to determine in patients with localized RCC (stages I-III) if the three-year disease-free survival is associated with detection of ctDNA in plasma immediately after surgery. 1.2 Secondary objectives 2. To show that detection of ctDNA pre- and post-operatively can be applied as a risk stratification tool. 3. To validate the potential of a ctDNA-guided follow-up program as compared to the current CT-scan follow-up program. More specifically, to investigate the correlation between ctDNA and CT-scanning findings. The potential is that ctDNA analysis predicts the CT-scan result and can be used to guide when to perform a CT-scan. Potentially, it also adds evidence for the results of CT-scans performed subsequently to an uncertain CT-scan result. 4. To investigate if time to Molecular recurrence using serial ctDNA analysis of longitudinally collected blood samples is shorter than time to Clinical recurrence using standard-of-care radiological imaging surveillance. 5. To find and validate predictive blood- and or tissue-based biomarkers for immunotherapy and or targeted therapies with the aim to identify patients that are more likely to respond to the given therapy administered. 6. To confirm that changes in ctDNA levels reflect the therapeutic effect of the given therapy, such as immunotherapy and or targeted therapies. 7. To delineate markers of tumor aggressiveness and compare to ctDNA measurements 2 INVESTIGATIONAL PLAN 2.1 Overall study design This study is based on a comprehensive series of blood sampling prospectively and ctDNA analysis performed in RCC patients before and after surgery, during and after treatment, and during surveillance. Patients are followed 5 years from date of surgery. * Urine, blood sampling and ctDNA analysis pre-operative and immediately after surgery (a postoperative blood sample is drawn on day 14) * Sampling of tissue from the biopsy and resected specimen as well as adjacent normal. * Longitudinal blood and urine sampling over a 5-year surveillance period - a blood and urine sample will be drawn simultaneously with the standard-of-care CT-scan-based surveillance program, and from metastatic tissue if a relapse occurs.
