This protocol covers primary lymphoma of bone presenting as anaplastic large cell lymphoma (ALCL) that has been completely resected at stage I, in patients younger than 18 years at diagnosis. Both criteria — confirmed ALCL histology with complete surgical resection at stage I, and pediatric age — define eligibility for this first-line approach.
Completely resected stage I ALCL in a pediatric patient represents a localised, surgically controlled disease. This specific combination of histological subtype, disease extent, resection status, and age bracket drives a tailored chemotherapy strategy rather than a general non-Hodgkin lymphoma approach.
Stage I ALCL: completely resected stage I: prephase (V) + AM - BM - AM courses
<18 years old at diagnosis.
