Filter by:RATIONALE: Interleukin-12 may kill tumor cells by stopping blood flow to the tumor and by stimulating a person's white blood cells to kill their tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of interleukin-12 in treating patients with AIDS -related Kaposi's sarcoma.
RATIONALE: Thalidomide may kill cancer cells by stopping the growth of new blood vessels to the tumor. PURPOSE: Phase II trial to study the effectiveness of thalidomide in treating patients with HIV-associated Kaposi's sarcoma.
BACKGROUND: - A number of important scientific advances can be made through the study of blood, bone marrow, tumor, or other tissue samples from patients with HIV infection, infection with Kaposi s sarcoma associated herpesvirus (KSHV), infection with other oncogenic viruses, or cancer. - This protocol provides a mechanism to affect a variety of such studies. OBJECTIVES: -Acquisition of serum, circulating cells, bone marrow, and tumor or normal tissue samples from participants with HIV infection, KSHV infection, or with cancer. ELIGIBILITY: -Eligibility criteria include age 18 years or older and at least one of the following: Exposure risk to HIV, KSHV, or HPV; HIV seropositive; KSHV seropositive; EBV seropositive; HTLV-1 seropositive; malignancy, Castleman s disease, or skin lesions with appearance of Kaposi s sarcoma; or cervical or anal intraepithelial lesion. DESIGN: - Up to 999 subjects will be enrolled in this study. - Blood samples may be collected at the initial visit, and at follow-up visits. - Other fluids/excretions may be collected (such as urine, saliva, semen, and stool). - Tumor samples may be obtained by fine needle aspirate, by removal of pleural or peritoneal fluid, by skin punch biopsy, or by excisional biopsy, providing the tumor is accessible with minimal risk to the participants. - Specific risks will be described in a separate consent to be obtained at the time of the biopsy. - Samples will be studied in the HIV and AIDS Malignancy Branch, CCR, NCI; laboratories in NCI-Frederick; or those of collaborating investigators.
To determine the seroprevalence of Kaposi's sarcoma-associated herpesvirus (KSHV/HHV8) in blood donors from Texas. Also to examine the donors' demographic characteristics and to characterize the KSHV using polymerase chain reaction.
Phase I trial to study the effectiveness of EMD 121974 in treating patients who have HIV-related Kaposi's sarcoma. EMD 121974 may stop the growth of Kaposi's sarcoma by stopping blood flow to the tumor.
Background: Kaposi s sarcoma (KS) is caused by a gammaherpesvirus called Kaposi s sarcoma-associated herpesvirus (KSHV), or human herpesvirus-8 (HHV-8). However, infection with KSHV is not sufficient to cause KS, and HIV infection is an important cofactor. Treatment of HIV with potent antiretroviral therapy can reduce the risk of KS, and can also induce regression in patients with established HIV-KS. One mechanism by which HIV is believed to contribute to KS is through HIV-induced immunodeficiency which leads to a loss of immunologic control of KSHV and/or KS itself. However, other mechanisms may also contribute. Objectives: One primary objective is to assess the effects of the initiation of potent anti-HIV therapy on specific factors possibly linked to the control or pathogenesis of KS, namely serum viral IL-6 and plasma VEGF levels, in patients with KS or at risk for KS by virtue of being infected with KSHV/HHV-8. Another is to assess the effects of anti-HIV therapy on KSHV infection. Secondary objectives are to assess the effects of potent antiretroviral therapy on established KS and other factors related to KS or KSHV infection. Eligibility: The principal eligibility factors are age 13 or above, HIV infection, and either KS or infection with KSHV. Exclusion factors include KS that requires specific therapy, recent corticosteroid therapy, recent cytokine therapy, or opportunistic infections requiring therapy. Design: Patients will be treated with potent antiretroviral therapy. For patients with established KS, the effects of the therapy on the KS will be monitored. In addition, a variety of factors related to KS, HIV infection, therapy, or KSHV infection will be monitored. These include the HIV viral load, KSHV secretion in saliva, the CD4 count, serum VEGF levels, and serum IL-6 levels.
The purpose of this study is to test the effectiveness of SU5416 in patients with AIDS-related Kaposi's sarcoma (KS).
RATIONALE: SU5416 may stop the growth of Kaposi's sarcoma by stopping blood flow to the tumor. PURPOSE: Phase II trial to study the effectiveness of SU5416 in treating patients who have AIDS-related Kaposi's sarcoma.
RATIONALE: SU5416 may stop the growth of Kaposi's sarcoma by stopping blood flow to the tumor. PURPOSE: Phase I trial to study the effectiveness of SU5416 in treating patients who have AIDS-related Kaposi's sarcoma.
RATIONALE: HIV virus is found in the lesions of most patients with Kaposi's sarcoma, and may have a role in causing Kaposi's sarcoma. Antiviral therapy acts against the HIV virus and may be an effective treatment for Kaposi's sarcoma. PURPOSE: This phase II trial is studying how well antiviral therapy works in treating patients with slowly progressing HIV-related Kaposi's sarcoma.
