ALK and anaplastic large cell lymphoma: Several comparison studies describing approaches from a variety of reinduction chemotherapy combined in relevant publications with autologous or allogeneic HSCT have shown the majority of patients with relapsed ALK+ ALCL can be rescued.[15] Allogeneic HSCT is an effective rescue therapy for high-risk ALCL relapse treatment and has acceptable toxicity.[16] This clinical observation of the efficacy of allogeneic HSCT for patients with relapsed ALCL also suggests a possible graft-versus-ALCL effect.
