title: A consensus protocol: Image-improved therapeutic guidelines for limited adult Hodgkin's disease.
abstract: Hodgkin's disease (HD) has greatly benefited from new technologies in terms of less invasive and more accurate staging as well as improved overall and relapse-free survival. However, the likelihood of late adverse effects of treatment, including second tumors, has increased due to the longer survival of patients with HD. Today's trend is to aim at minimal therapeutic exposure while guaranteeing lower therapy-related morbidity. This encourages new research efforts but also leads to less uniformity in treatments, as observed in the Veneto Region in Italy. The Gruppo Veneto Linfomi, composed of representatives of Radiotherapy and Oncology Departments of the Veneto Region, has been analyzing this problem and proposing therapy guidelines since 1995. A set of 10 prognostic factors has been developed to identify three prognostic groups: highly favorable (HF) are patients up to 40 years of age presenting with stage I disease involving only one site of disease with a maximum tumor diameter (TD) of 5 cm and no adverse factors. In this group only mantle field irradiation is recommended if the disease is located in the neck or above, inverted-Y irradiation is recommended for distal subdiaphragmatic lesions, and subtotal nodal irradiation in all other cases. HF cases may also be treated like favorable cases with limited chemoradiation. Favorable (F) cases are patients in stage I with a TD greater than 5 cm and smaller than 10 cm or stage II, up to three sites of disease and negative prognostic factors for systemic disease. All other patients are included in the "not favorable" (NF) group at Ann Arbor stage I or II with any adverse prognostic factor. For the latter two groups, chemotherapy with the ABVD or Stanford V regimen precedes involved-field radiotherapy to sites with a TD of at least 5 cm. The total irradiation dose is determined by local disease extent and level of response to chemotherapy. Images on which the radiation fields are drawn serve as an important reference to improve the homogeneity of treatments. This protocol includes a list of adverse treatment effects (chemo- and/or radiotherapy) together with follow-up guidelines for the early detection of secondary cancers in previously irradiated patients.
