Abstract
In early stage Hodgkin's disease the optimal choice of treatment for the individual patient is still an unresolved issue. So far, twenty-two randomized trials of radio therapy alone versus radiotherapy plus combination chemotherapy have been carried out worldwide. The preliminary results of a global metaanalysis of these trials indicate that we still do not definitively know whether or not the addition of prophylactic chemotherapy up front improves survival. Arguments in favour of the addition of chemotherapy up front are: that laparotomy may be avoided, that radiation fields and doses may perhaps be reduced, and that the stress of experiencing a relapse is avoided in many patients. The major argument against the use of chemotherapy up front is: that by careful staging and selection of patients and by careful radiotherapy techniques the number of patients exposed to potentially toxic chemotherapy may be kept at a minimum. Recently, trials have been carried out testing chemotherapy alone. The results of these trials are however conflicting. In order not to jeopardize the good results achieved with the standard treatments developed over the last three decades, newer treatment approaches should be carefully tested in large randomized trials before being implemented for general clinical use.
