Summary Early‐stage classical Hodgkin lymphoma (HL) patients are evaluated by an end‐of‐chemotherapy positron emission tomography‐computed tomography (eoc‐PET‐CT) after doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD) and before radiation therapy (RT). We determined freedom from progression (FFP) in patients treated with ABVD and RT according to the eoc‐PET‐CT 5‐point score (5PS). Secondarily, we assessed whether patients with a positive eoc‐PET‐CT (5PS of 4–5) can be cured with RT alone. The cohort comprised 174 patients treated for stage I‐II HL with ABVD and RT alone. ABVD was given with a median of four cycles and RT with a median dose of 30·6 Gy. Five‐year FFP was 97%. Five‐year FFP was 100% (0 relapses/98 patients) for patients with a 5PS of 1–2, 97% (2/65) for a 5PS of 3, 83% (1/8) for a 5PS of 4, and 67% (1/3) for a 5PS of 5 ( P < 0·001). Patients with positive eoc‐PET‐CT scans who were selected for salvage RT alone had experienced a very good partial response to ABVD. Risk factors for recurrence in this subgroup included a small reduction in tumour size and a ‘bounce’ in ≥1 PET‐CT parameter (reduction then rise from interim to final scan). Thus, a positive eoc‐PET‐CT is associated with inferior FFP; however, appropriately selected patients can be cured with RT alone.
