Individualisierte Strahlentherapie des Hodgkin-Lymphoms
摘要
With the individual reduction of radiation field sizes and positron-emission tomography (PET)-guided radiotherapy (RT), benefit-adapted individualization of RT has become standard in the setting of combined modality therapy for Hodgkin lymphoma (HL). In recent years, the concept of combined benefit- and risk-adapted individualization has also been developed.
PurposeThis article aims to present the various concepts of individualized RT for HL.
Materials and methodsA review of the individualization of RT for HL was performed using a literature search in PubMed.
ResultsDue to the young patient population and the good prognosis, reducing the long-term toxicity of HL treatment is particularly relevant. The long-term toxicity of RT has already been significantly reduced by decreasing the size of the radiation fields to involved-site radiotherapy (ISRT) and establishing PET-guided RT. In contrast to this established benefit-adapted individualization of RT, combined benefit- and risk-adapted individualization also takes into account the individual risk of long-term toxicities, so that affected lymph node areas may spared irradiation in order to avoid long-term toxicities. Models that enable this assessment in a preclinical context already exist. However, they have not yet been validated, which precludes their use in everyday clinical practice.
ConclusionThere are promising approaches to the combined benefit- and risk-adapted individualization of radiation therapy for Hodgkin lymphoma, but these cannot yet be used in routine clinical practice due to a lack of validation. However, they will become more relevant in the future.
