Data from 20 years of cancer registration in Harare (Zimbabwe) are used to investigate the risk of cancer in the white population of the city (of European origin), relative to that in blacks (of African origin). In the absence of information on the respective populations-at-risk, we calculated odds

Skin tumors induced by the subcutaneous injection of 3-methylcholanthrene (3-MC) in New Zealand Black (NZB) mice had a delayed development and lower frequency compared with BALB/c and C57BL mice. In the SJL/J strain, the incidence of tumors was lower than in the NZB, but with the same delayed

β-1,3-1,6-glucans are the most abundant glucose polymers in the cell walls of fungi. Previous studies have shown that β-1,3-1,6-glucans derived from fungi possess immunomodulating activitivies. Antitumor effects of these compounds have also been reported in animal models. Current studies mainly

The polyanionic species suramin is a potential anti-cancer agent of narrow therapeutic index. Among other pharmacological characteristics, suramin is an inhibitor of angiogenesis. We have targeted its angiostatic properties as part of a program to discover less toxic analogs. From screening a series

The Celebes black macaque (Macaca nigra) colony at the Oregon Regional Primate Research Center has a high incidence of an immunodeficiency syndrome characterized by recurrent diarrhea and the development of retroperitoneal fibromatosis (RF). We have examined the relationship of type D viral

BACKGROUND Infection with human herpesvirus 8 (HHV-8), also known as Kaposi's sarcoma-associated herpesvirus (KSHV), is the necessary causal agent in the development of Kaposi's sarcoma (KS). Infection with HIV-1, male gender and older age all increase risk for KS. However, the geographic

BACKGROUND Childhood sarcomas are rare and require complex interdisciplinary care including surgery, chemotherapy, and radiation. The goal of this study was to determine if racial or ethnic disparities exist for pediatric sarcoma patients in the United States. METHODS The United States' National

Soft tissue sarcomas (STS) are a heterogeneous group of uncommon tumors that show a broad range of differentiation that may reflect etiologic distinction. Routine tabulations of STS are not morphology-specific. Further, the lack of inclusion of sarcomas arising in all organs in most standard

BACKGROUND Granulocytic sarcomas (GS) have been associated with t(8;21). The prognosis of patients with GS is generally regarded as being less favorable than of patients with acute myeloblastic leukemia (AML). GS occurs relatively commonly in Africa and has been reported to affect 10-25% of black

An HIV-1 antibody positive black African man with plasma cell variant Castleman's disease and cutaneous Kaposi's sarcoma, despite receiving chemotherapy, had progressive disease. In addition, he developed pain and swelling behind the right knee. Histology of an ultrasound guided biopsy showed

Little is known about the epidemiology of human herpesvirus 8 (HHV-8) infections among women. A cross-sectional study was conducted of HHV-8 infection among human immunodeficiency virus (HIV)-infected and high-risk HIV-uninfected women. Serological tests with noninduced (latent) and induced (lytic)

A 32-year-old black man, a homosexual patient with a history of lymphadenopathy, presented with diarrhea, weight loss, and a bilateral interstitial infiltrate. Within days after admission, the patient developed dyspnea with rapid progression to respiratory failure and a rapid increase of the

An HIV positive black African woman presented with widespread lymphadenopathy and pancytopenia that had been ascribed to tuberculosis. Lymph node biopsy showed both Kaposi's sarcoma and multicentric Castleman's disease. Despite antiretroviral therapy and chemotherapy the patient deteriorated,
