Circulating Tumor Cells (CTCs) Circulating tumor cells are rare cancer cells that detach from a primary tumor or metastases and enter the bloodstream. They can serve as biomarkers for cancer detection, monitoring, and prognosis, as they provide real-time insights into tumor activity without invasive biopsies. CTCs are associated with metastasis risk and treatment response, with higher counts often indicating disease progression. General research supports CTCs as clinically valid tools across various cancers, though detection methods vary in sensitivity and specificity. Oncotrace Cancer Test by RGCC The Oncotrace test, developed by RGCC (Research Genetic Cancer Centre, based in Switzerland with labs in Greece), is a liquid biopsy designed to detect and analyze CTCs in blood samples. It aims to establish a baseline cancer status, monitor treatment progress, identify tumor origins, and assess prognosis. Applicable to all cancer types, it is particularly used for patients with confirmed di...
