Abstract

Anaplastic large cell lymphomas (ALCLs) are rare CD30+ peripheral T-cell lymphomas (PTCLs) classified according to the expression of the anaplastic lymphoma kinase (ALK+) protein or not (ALK-). We have analysed the outcome and risk factors for survival in a population-based bi-national cohort of patients with systemic ALK+ ALCL. A total of 122 adult (≥18 years) patients diagnosed with ALK+ ALCL between 2000 and 2010 were identified from the Danish and Swedish lymphoma registries, representing 0·4% of all lymphomas. The median age of the cohort was 40 years (range 18-85). The 5-year overall survival and progression-free survival (PFS) was 78% and 64%, respectively. Age was strongly associated with outcome, and only bone marrow (BM) involvement was independently associated with poorer PFS in multivariate analysis (Hazard Ratio [HR] = 8·57, P < 0·001). Age stratification of the patients demonstrated an association between treatment with CHOEP (cyclophosphamide, doxorubicin, vincristine, etoposide, prednisolone) and improved overall survival for patients aged 41-65 years, even when adjusted for risk factors (HR = 0·38, P = 0·047). Our results suggest that the addition of etoposide to CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone) in the treatment for ALK+ ALCL seems reasonable in this age group.
