Hodgkin lymphoma, even in advanced‐stage, is a highly curable malignancy, but treatment is associated with short‐term toxicity and long‐term side effects. Early predictive markers are required to identify those patients who do not require the full‐length standard therapy (and thus qualify for therapy de‐escalation) and those patients who will not be cured by standard therapy (and thus qualify for therapy escalation). Multiple trials have assessed the value of 18 F‐fluoro‐2‐deoxy‐ d ‐glucose positron emission tomography ( FDG ‐ PET ) after a few cycles of chemotherapy (also known as ‘interim FDG ‐ PET ’) in predicting outcome in advanced‐stage Hodgkin lymphoma. Furthermore, multiple interim FDG ‐ PET ‐adapted trials, in which patients with positive interim FDG ‐ PET scans are assigned to escalated therapies, and patients with negative interim FDG ‐ PET scans are assigned to de‐escalated therapies, have recently been published or are currently ongoing, with generally heterogeneous results. The present article reports the currently available evidence (and controversies) on the prognostic value of interim FDG ‐ PET in advanced‐stage Hodgkin lymphoma in patients with positive and negative interim FDG ‐ PET findings following continuation of standard chemotherapy or escalated/de‐escalated therapy.
