Childhood anaplastic large cell lymphoma (ALCL) is a well defined entity with a rather poor prognosis. Different approaches have been adopted in the treatment of ALCL in various cooperative trials, including short high-dose intensive therapy and leukemia-like protocols. In the early 1990s, the Italian Association of Pediatric Hematology and Oncology (AIEOP) initiated a multicenter trial for the treatment of ALCL based on a modified LSA2-L2 protocol.
Thirty-four consecutive eligible children with newly diagnosed ALCL were enrolled in the AIEOP LNH-92 protocol. Treatment was comprised of an induction of remission phase, followed by consolidation and maintenance for a total duration of 24 months, independently of disease stage.
Thirty of 34 patients (88%) achieved complete disease remission and 8 patients experienced disease recurrence. With a median follow-up of 8.4 years, the probabilities of survival and event-free survival were 85% (range, 79-91%) and 65% (range, 57-73%), respectively. Therapy was well tolerated and hematologic toxicity was the most frequent toxicity.
The leukemia-like protocol AIEOP LNH-92 was found to be an effective treatment for childhood ALCL. Its long duration may be beneficial to specific patient subgroups, but optimal treatment duration in ALCL remains to be elucidated.
