Circulating Chromogranin A as Surveillance Biomarker in Patients with Carcinoids – The CASPAR Study
Purpose: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are relatively indolent but can be more aggressive. The current recommendations for the use of serum CgA for GEP-NET patients are equivocal. This study was designed to validate an automated CgA immunofluorescence assay for monitoring disease progression in GEP-NET patients. Patients and Methods: A prospective, multi-center blinded observational study was designed to validate an automated chromogranin A (CgA) immunofluorescence assay for monitoring disease progression in GEP-NET patients. Tumor progression was evaluated with Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 by CT/MRI. An increase ≥ 50% above the prior CgA concentration to a value > 100 ng/mL in the following CgA concentration was considered positive. Results: 153 GEP-NET patients were enrolled. Using the pre-specified cut-off of CgA change for tumor progression, specificity was 93·4% (95%-CI: 90·4%—95·5%, p < 0·001), sensitivity 34·4% (25·6%—44·3%), positive predictive value 57·9% (45·0—69·8), negative predictive value (NPV) 84·3% (80·5—87·6), and area under the curve 0·73 (0·67—0·79). Conclusions: Changes in serial measurements of serum CgA had a favorable specificity and NPV, making this test a useful adjunct to routine radiographic monitoring.
期刊介绍:
Clinical Cancer Research is a journal focusing on groundbreaking research in cancer, specifically in the areas where the laboratory and the clinic intersect. Our primary interest lies in clinical trials that investigate novel treatments, accompanied by research on pharmacology, molecular alterations, and biomarkers that can predict response or resistance to these treatments. Furthermore, we prioritize laboratory and animal studies that explore new drugs and targeted agents with the potential to advance to clinical trials. We also encourage research on targetable mechanisms of cancer development, progression, and metastasis.
