The current report focuses on the characterization and evaluation of outcomes in 235 (15%) cases of ALK– ALCL....Treatment with anthracycline and etoposide was associated with a superior outcome: 3-year and 5-year OS rates were 56% and 44% in the anthracycline-based treatment group, and 76% and 69% in the anthracycline/etoposide–based treatment group, and the differences were statistically significant (P = .05). Similar results were also observed in PFS.
