Multilobated B-cell lymphoma. A clinicopathologic study of 24 cases.
The clinical, histologic, and immunologic features of 24 cases of multilobated B-cell lymphoma are presented and compared with those of previously reported cases. Cases were included in this study when more than 50% of the tumor cells had nuclear multilobation. There were 13 males and 11 females with an age range of 13 to 79 years. A slight predominance of node-based presentations was observed. Seventeen patients (71%) presented with advanced (stage III or IV) disease. Complete remissions were achieved in 13 (59%) of 22 patients, and 14 (58%) of the 24 patients were still alive after a follow-up period ranging from 10 to 124 months. The 1-year survival was 65% (SE = 10%). Relapses occurred in 4 (31%) of 13 patients with complete responses. These observations, together with those previously reported, support the conclusion that the multilobated B-cell variant of non-Hodgkin's lymphoma behaves in a fashion similar to that of the intermediate-grade, diffuse, large-cell non-Hodgkin's lymphomas.
