PET performed after 2 cycles of chemotherapy (PET2) allows prediction of outcome in most patients with Hodgkin lymphoma (HL). Visual analysis using a 5-point scale was proposed to assess PET response, but a semiquantitative approach using maximum standardized uptake value (SUVmax) reduction between baseline and interim PET was shown to be superior to the 5-point scale in patients with diffuse large B-cell lymphoma and may also improve the accuracy of interim PET interpretation in HL. To compare the clinical usefulness of both methods in HL patients, we analyzed PET2 according to visual and ΔSUVmax criteria in a retrospective single-center study. From 2007 to 2010, 59 consecutive patients with a first diagnosis of HL were treated with 4–8 cycles of anthracycline-based chemotherapy. Radiotherapy was performed in 19 responding patients with localized disease. PET was done at …
