[Initial treatment strategy for classical Hodgkin lymphoma in adults].

Four cycles of ABVD followed by 30 Gy IFRT (ISRT) is a standard regimen, as an initial treatment, for patients with early-stage classical Hodgkin lymphoma (cHL), whereas 2 cycles of ABVD followed by 20 Gy IFRT (ISRT) is an alternative regimen for those with favorable early-stage cHL. For patients with unfavorable early-stage cHL including bulky disease, local radiotherapy can be safely omitted if negative findings on interim PET are obtained after 2 cycles of escalated BEACOPP plus 2 cycles of ABVD. ABVD (6/8 cycles) or brentuximab vedotin (BV) with concurrent AVD (6 cycles) is a standard regimen for patients with advanced-stage cHL. For elderly cHL patients (60 years of age or older) and multiple comorbidities, the risk of treatment-related adverse events is higher, which can potentially lead to poor outcomes. BV with sequential AVD therapy, which is a unique combination strategy, has been developed for elderly cHL patients. The combination of anti-PD-1 antibodies with AVD therapies is currently being evaluated in some clinical trials. This review includes current evidence that primarily focuses on randomized clinical trials for newly diagnosed adult cHL patients and management points in clinical practice for those patients.
