Objective: To describe treatments and outcomes of French children treated for relapsed/refractory anaplastic lymphoma kinase-positive anaplastic large cell lymphoma (ALK+ ALCL).
Methods: We conducted the analysis of a series of 75 French children treated for a first relapsed/refractory ALK+ ALCL between 1999 and 2017.
Results: The median time to first relapse was 8.
Purpose: Describe clinical characteristics and outcome of Li-Fraumeni syndrome (LFS)-associated osteosarcomas.
Methods: TP53 germline pathogenic/likely pathogenic variant carriers diagnosed with osteosarcoma in France between 1980 and 2019 were identified via the French Li-Fraumeni database at Rouen University Hospital. Sixty-five osteosarcomas in 52 patients with available clinical and histological data were included.
