Hodgkin's disease in American Negroes. Histologic classification of the disease in 143 untreated patients, and age distribution.
The Rye histologic classification of Hodgkin's disease has been applied to 143 previously untreated cases of Hodgkin's disease in Negro patients seen in four hospitals in Washington, D.C.,during a 16-year period (1959-1974). The frequencies and age distributions of histologic subtypes were compared with those in American and two African series. Those histologic subtypes associated with poor prognoses (mixed-cellularity and lymphocytic depletion) predominated in American Negroes and in Negroes from Ibadan, Nigeria, and Kampala, Uganda. In an American series from Connecticut (approximately 98% Caucasian) the histologic subtypes lymphocytic predominance and nodular sclerosis were preponderant. There were statistically significantly less of the nodular sclerosis subtype (P less than 0.005), and more of the mixed-cellularity subtype in American Negroes compared with the Connecticut series (P less than 0.001). In contrast to findings in predominantly Caucasian populations, there was a predilection of the nodular sclerosis subtype for males in American and in African Negroes. This study showed that Hodgkin's disease in American Negroes epidemiologically corresponds to the so-called "intermediate pattern" of the disease.
