title: Immunoblastic sarcoma: a clinical description.
abstract: We reviewed the clinical records of 33 patients with Immunoblastic Sarcoma in order to further describe this disease clinically. Several common features were found. Thirty percent of the patients had a history of a prior immune disease or lymphoproliferative malignancy. Forty-four percent of the patients tested had a diffuse hypergammaglobulinemia. Lymphopenia (less than 1,000/mm3) was found in 45%, and anemia occurred in 73%. At initial presentation, 30% of the cases were clinically staged as either stage I or II, whereas 70% were found to be stage III or IV. Forty-nine percent of the patients had systemic symptoms at presentation. The median survival was 14 months. Advanced stage of disease, lymphopenia, and presence of systemic symptomatology were associated with significantly decreased survival times (p less than .05). We conclude that IBS is a clinical entity often associated with prior immune disease and/or diffuse hypergammaglobulinemia.
