title: How does PET/CT help in selecting therapy for patients with Hodgkin lymphoma?
abstract: Positron emission tomography/computed tomography (PET/CT) has emerged as the most accurate tool for staging, treatment monitoring, and response evaluation in Hodgkin lymphoma (HL). Accurate staging and restaging are very important for the optimal management of HL, but we are only beginning to understand how to use PET/CT to improve treatment outcome. More precise determination of disease extent may result in more precise pretreatment risk stratification, and is also essential for the minimal and highly individualized radiotherapy volumes of the present era. Several trials are currently investigating the use of PET/CT for early response-adapted therapy, with therapeutic stratification based on interim PET/CT results. Posttreatment PET/CT is a cornerstone of the revised response criteria and enables the selection of advanced-stage patients without the need for consolidation radiotherapy. Once remission is achieved after first-line therapy, PET/CT seems to have little or no role in the routine surveillance of HL patients. PET/CT looks promising for the selection of therapy in relapsed and refractory disease, but its role in this setting is still unclear.
