[Hodgkin's disease: the value of prognostic criteria and of the combination of radiotherapy and chemotherapy in localised lymphoid stages (I and II). 94 patients undergoing laparotomy (author's transl)].

Criteria reputed to be of grave prognostic significance were studied in 94 patients suffering from Hodgkin's disease at stages I and II, after laparotomy and splenectomy. The parameters studied (age, general signs, histological type, mediastinal involvement) are less prognostic factors than indications of unrecognised extension of the disease: almost 1/3 of unrecognised lesions in the presence of one of the criteria; almost 2/3 with two or more. Exploratory laparotomy revealed lesions unsuspected on the basis of clinical evaluation only in 10% of patients with no criteria of poor prognosis. The long term prognosis of the disease depends, in fact, not upon the existence of these criteria but upon the method used in initial treatment. Five year survival and cure rates are significantly better in patients treated with combined polychemotherapy (MOPP) and radiotherapy than in those treated with radiotherapy alone. These results would indicate that routine laparotomy should be abandoned in patients with a localised clinical staging if it is decided to begin treatment with a combination of radiotherapy and chemotherapy. So-called prognostic factors could then be used simply to vary the intensity of the treatment prescribed.
