Clinical features of Hodgkin's disease in Cuba and Sweden.

A clinical study of 182 Swedish and 164 Cuban consecutive adult patients with Hodgkin's disease was performed comparing age, sex, histopathology, clinical stage, symptoms, and various laboratory tests. A bimodal age distribution was observed which was more pronounced in the Swedish series. A male/female ratio 1.8/1.0 in both samples was observed. Nodular sclerosis and Stage IA and IIA were more common in Swedish patients while in the Cuban, mixed cellularity and Stage IIIB and IVB dominated in patients below fifty years of age. The Swedish patients exhibited an age distribution similar to that found in other industrialized Western countries, while the Cuban patients had an age distribution pattern typical for countries with an intermediate epidemiological pattern.
