The FIL-Rouge design provides an ideal environment for validating the liquid biopsy in Classical Hodgkin lymphoma (cHL), since one arm of the study will utilize a PET/CT-adapted strategy (Positron Emission Tomography/Computed Tomography)for treatment, while the second arm will be devoid of any PET/CT-adaptation of therapy. Also, estimating prospectively differences in residual disease between the two study arms of the FIL-Rouge will provide an important biologic tool to validate the concept of dose-intensification within the ABVD therapeutic platform.~This study aims at the prospective validation of the concept of the liquid biopsy as a biomarker for disease response assessment in cHL. The patients enrolled in the FIL-Rouge clinical trial at the centers participating in this study and consenting to the biological study FIL-RougeBIO will be considered for this study. After providing written informed consent, relevant patients will be evaluated for detecting cancer gene mutations in ctDNA (Circulating Tumor DNA) for measuring residual disease. All clinical data useful for data analyses of this study will derive from the FIL-Rouge clinical trial.~Given the non-interventional design of the study, project participants will not have immediate potential benefits.The enrollment in FIL-RougeBIO will parallel the original protocol until reaching the 500 programmed patients. The results of this study could benefit future patients with the same condition.
