Filter by:Background: A person s genome is the collection of all their genes. A gene instructs individual cells to make proteins. Proteins are involved in all of our body s chemical processes. Genome sequencing allows researchers to find variations in genes. Some of these are normal and are not known to cause disease. Some variants are known to cause or affect diseases like cancer. Researchers want to study genetic variants in people with cancer who also have an immunologic disease like HIV. Objective: To study the biology of cancer in order to improve ways to prevent, detect, and treat it. Eligibility: Adults at least 18 years old with certain cancers and/or immunodeficiencies Design: Participants will be screened with medical history, physical exam, and lab tests. Participants will give samples of one or more tissue type. They may give blood or urine samples. Researchers may get samples of tissue when participants have surgery or when the participants are on other protocols in the NCI. Participants may have a procedure to have tissue samples removed. Researchers may collect data from participant medical records. Researchers will compare the genes in a participant s cancer tissue to their normal tissue. They may use the tissue cells to grow new cells in a lab. Participants may be contacted about the results. The samples will be stored for future research. No personal data will be kept with them. ...
Classic and endemic Kaposi's sarcoma (KS) are lymph angio proliferations associated with human herpes virus 8 (HHV8) which treatment is poorly codified. Chemotherapies give at best 30-60% of transient responses. While interferon responses are frequent, this drug is often poorly tolerated in elderly patients. Therefore new therapies are needed. Classic KS represents an ideal model for evaluating new drugs since patients do not receive concomitant immunosuppressive regimens nor antiviral therapies. Hypoxia-inducible factor 1(HIF-1 alpha) is a major regulator of solid tumor growth and therefore a suitable target currently explored in many cancers. Moreover HIF-1 alpha enhances HHV-8 gene expression in KS and induces lytic replication cycle. Digoxin has anti cancer effect in vivo through HIF-alpha down regulation in several preclinical tumor models including KS. The identification of HIF-1 alpha as a key factor in HHV8 replication prompt us to explore inhibition of HIF-1 alpha by digoxin as a potential therapeutic approach for KS treatment it has and consequently may down regulate HHV-8 replication in KS. This latter approach is heightened by recent data suggesting that Digoxin has some efficacy in vitro against others human herpes virus i.e. Herpes simplex and Cytomegalovirus (8) (9) In this study the investigators shall evaluate the benefit and safety profile of digoxin in classic and endemic KS (serum drug concentration of 0.6 to 1.2 ng/ml for patients <75 years and between 0.5-0.8 ng/ml in patients older than 75 years The participants will take study drug digoxin, for a total of 6 cycles (4 weeks/cycle).
The purpose of this study (NAV3-12) is to determine the dissemination and localization of Tc 99m tilmanocept by SPECT and SPECT/CT imaging in subjects with confirmed cutaneous KS. This is a single center, open-label, within-subject study.
This is a pilot study to determine the efficacy, kinetics and safety of aldoxorubicin in HIV positive subjects with Kaposi's sarcoma.
AIDS-related Kaposi's sarcoma (AIDS-KS) occurs in persons with HIV infection who are also infected with the Kaposi's sarcoma herpesvirus (KSHV). Several chemotherapy (anti-cancer) drugs work well in treating KS, but there is no treatment that cures KSHV infection. One chemotherapy drug called etoposide (VePesid®, ET) has caused KS tumors to get smaller in some people. Antiretroviral therapy (anti-HIV drugs or ART) is a group of medicines taken together to treat HIV infection. These medicines help to stop HIV from growing in the body. When this happens, the immune system, which fights infection and some cancers like KS, gets stronger. For some people, limited stage KS often improves or stays the same when they take ART. However, in some people KS continues to get worse when taking ART. These people may need chemotherapy at a later date. This study was done to find out if taking ART with immediate etoposide (ET) is better than taking ART alone or ART with delayed ET to treat limited stage KS. The study also tried to better understand KSHV and to see what kind of side effects are caused by ART and ET and how safe ART and ET are.
Kaposi sarcoma remains the most common malignancy among persons with HIV. Lesions localized to the airway may cause bleeding, pain and dyspnea. New therapeutic approaches for local disease are needed. The purpose of this study is to compare the effectiveness of intralesional bevacizumab + HAART vs HAART alone in treating localized Kaposi´s sarcoma of the airway in patients with AIDS.
The purpose of this pilot study is to determine whether Maraviroc is effective in the treatment of Kaposi's Sarcoma (KS), when it does not remit with standard antiretroviral drug therapy.
The purpose of this study is to determine the clinical response to daily Indinavir oral administration in association with a conventional chemotherapy based on cycles of systemic Vinblastine +/- Bleomycin in patients affected by advanced classical (non HIV-associated) Kaposi's sarcoma
This research is being done to determine whether viral thymidine kinase (TK) expression in Epstein-Barr virus (EBV) and Kaposi's sarcoma herpesvirus (KSHV) virus-associated tumors is sufficient to image.
RATIONALE: PTC299 may stop the growth of Kaposi sarcoma by blocking blood flow to the tumor. PURPOSE: This phase I/II trial is studying the side effects and best dose of PTC299 and to see how well it works in treating patients with HIV-related Kaposi sarcoma.
