Relationship of histopathologic features to survival and relapse in nodular sclerosing Hodgkin's disease. A study of 1659 patients

Nodular sclerosing (NS) Hodgkin's disease (HD) with extensive areas of lymphocyte depletion or with numerous anaplastic Hodgkin's cells, termed Grade II NS, is associated with a poor response to initial therapy, an increased relapse rate, and decreased survival when compared with other NS variants, termed Grade I NS. The histopathologic subdivision of NS HD into Grade I and Grade II is easy to perform and provides essential prognostic information that is independent of stage. Patients with Grade II NS HD may require more aggressive initial therapy if their survival is to be improved.
