Stage I and II Hodgkin's disease presenting in infradiaphragmatic nodes

Twenty patients with Hodgkin's disease limited to infradiaphragmatic (ID) nodes have been treated at the University and Hospital Radiotherapy Departments in Florence between 1960 and 1978. Clinicopathologic features and treatment modalities of these patients were reviewed and results compared with those of 2 similar series previously published by other authors. With respect to the patients with disease above the diaphragm, the ID presentation occurred more often in males in all the 3 reviewed series; a relative prevalence of the lymphocytic predominance histotype and of an older age was observed in 2 only of the 3 series; laparatomy seems unnecessary in lymphographic-negative patients. The analysis of therapeutic results suggests that inverted Y irradiation is a sufficient treatment when inguinal or lower iliac nodes only are affected; paraortic region and spleen involvement warrant a more radical program including the supradiaphragmatic irradiation or systemic chemotherapy.
