Abstrakt: The primary analysis of the GHSG HD16 trial indicated a significant loss of tumor control with PET-guided omission of radiotherapy (RT) in patients with early-stage favorable Hodgkin lymphoma (HL). This analysis reports long-term outcomes. Overall, 1150 patients aged 18–75 years with newly diagnosed early-stage favorable HL were randomized between standard combined-modality treatment (CMT) (2x ABVD followed by PET/CT [PET-2] and 20 Gy involved-field RT) and PET-2-guided treatment omitting RT in case of PET-2 negativity (Deauville score [DS] < 3). The study aimed at excluding inferiority of PET-2-guided treatment and assessing the prognostic impact of PET-2 in patients receiving CMT. At a median follow-up of 64 months, PET-2-negative patients had a 5-year progression-free survival (PFS) of 94.2% after CMT (n= 328) and 86.7% after ABVD alone (n= 300; HR = 2.05 [1.20–3.51]; p= 0.0072). 5-year OS was 98.3% and 98.8%, respectively (p= 0.14); 4/12 documented deaths were caused by second primary malignancies and only one by HL. Among patients assigned to CMT, 5-year PFS was better in PET-2-negative (n= 353; 94.0%) than in PET-2-positive patients (n= 340; 90.3%; p= 0.012). The difference was more pronounced when using DS4 as cut-off (DS 1-3: n= 571; 94.0% vs. DS ≥ 4: n= 122; 83.6%; p< 0.0001). Taken together, CMT should be considered standard treatment for early-stage favorable HL irrespective of the PET-2-result.
