Long-Term Follow-up of SWOG S0816: Response-Adapted Therapy for Stage III/IV Hodgkin Lymphoma Demonstrates Limitations of PET-Adapted Approach

ConclusionsThe long-term overall survival of the patients treated on S0816 remains high (94%) at 5 years. Despite historical data suggesting favorable clinical outcomes in patients with a negative PET2, nearly 25% of these patients experienced relapse events, demonstrating limitations of a PET-adapted approach and of standard frontline therapy with ABVD. In patients who were PET2+, PFS was favorable relative to historical series, but was associated with a high rate of secondary malignancies. Our results emphasize the importance of long-term follow-up in this disease, and the need for better biomarkers at diagnosis of HL and less toxic approaches for patients with a positive PET2.AcknowledgementIn memory of Oliver W.
