Abstract
At the beginning of this conference, Dr Ford asked whether or not Hodgkin's disease was a malignancy. Most physicians would agree that, regardless of whether this question can be answered on a molecular level, Hodgkin's disease certainly behaves like a malignancy, and clinically fits criteria necessary to call it one. It grows without control locally, comprising vital organs. It ‘metastasizes’, infiltrates organs, and causes organ dysfunction. Patients afflicted with the disease have a shortened life span without proper therapy, as demonstrated by DeVita in his original publication describing the benefits of MOPP chemotherapy (nitrogen mustard, vincristine, procarbazine, prednisone) (DeVita et al., 1970). However, it can progress very slowly, with 50 per cent of untreated patients with stage III or IV disease dead at one year, but 10 to 15 per cent alive at five years. Therefore, in its clinical behaviour, Hodgkin's disease certainly qualifies as a malignant disorder, despite the fact that we do not have the molecular means of calling it one.
