Lymphocyte-depleted hodgkin's disease. Clinicopathologic review of 25 patients

Clinicopathologic material from 25 patients with lymphocyte-depleted Hodgkin's disease was reviewed. The median age of the patients was 57 years. The patients had no prior diagnosis of Hodgkin's disease and were divided according to pathologic subtype of lymphocyte-depleted Hodgkin's disease: 11 diffuse fibrosis, 10 reticular, and four not otherwise specified. The clinical presentation included B symptoms of fever, weight loss, or night sweats (92 percent), subdiaphragmatic disease (88 percent), frequent marrow involvement (56 percent), and advanced-stage disease (100 percent). Four of 11 patients with diffuse fibrosis had peripheral adenopathy as compared with seven of 10 patients with the reticular subtype (p = 0.3); 10 of 11 patients with diffuse fibrosis had marrow involvement compared with two of nine patients with the reticular subtype (p = 0.006). Among patients who received chemotherapy, median survival was longer in the diffuse fibrosis subtype (nine patients, 39 months) than in the reticular subtype (10 patients, 10 months), p = 0.005. Of the 17 patients who received more than one cycle of combination chemotherapy with mechlorethiamine, vincristine, procarbazine, and prednisone, the median survival was 36 months with 11 (65 percent) complete remissions. In eight patients, disease remains in remission (12 to 127 months) with five patients surviving beyond five years. These results indicate that lymphocyte-depleted Hodgkin's disease has at least two clinicopathologic subtypes and is curable if adequate therapy can be given.
