Filter by:The purpose is to assess the efficacy and toxicity of the study agent, enzastaurin, in participants with recurrent or persistent ovarian cancer.
The purpose of this study is to evaluate the presence of proteins in solid tumors which may lead to an immune response
The main objective of the trial is to explore the safety and biological activity of NGR-hTNF. The safety will be established by clinical and laboratory assessment. The biological activity will be evaluated by DCE-MRI with contrast media.
This is a randomized, open-label, multi-center study comparing the safety and efficacy of XRP6258 plus prednisone to mitoxantrone plus prednisone in the treatment of hormone refractory metastatic prostate cancer previously treated with a Taxotere®-containing regimen. The primary objective is overall survival. Secondary objectives include progression free survival, overall response rate, prostate-specific antigen (PSA) response/progression, pain response/progression, overall safety, and pharmacokinetics. Patients will be treated until disease progression, death, unacceptable toxicity, or for a maximum of 10 cycles. Patients will have long-term follow-up for a maximum of up to 2 years.
RATIONALE: Drugs used in chemotherapy, such as fluorouracil, leucovorin, and irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. PURPOSE: This phase II trial is studying how well combination chemotherapy works as first-line therapy in treating patients with locally advanced or metastatic neuroendocrine tumors of the duodenum or pancreas that cannot be removed by surgery.
This study will try to determine whether or not certain genes are responsible for the huge variation in toxicity and effect observed between patients treated with paclitaxel (chemotherapeutic drug). Specifically we will study this retrospectively in patients who participated in clinical trials that are now closed. All patients had ovarian cancer and received paclitaxel/carboplatin chemotherapy after primary surgery.

The purpose of this study is to compare the safety and efficacy of Proxinium plus best supportive care with best supportive care only for patients with squamous cell head and neck cancer.
Long term survival can now be achieved in 75% of cases of pediatric cancers. However, some types of tumors (ie CNS tumors) or advanced stages (metastatic sarcomas/neuroblastomas) cannot be cured by any treatment. Thus, evaluation of new drugs or combinations are strongly needed. The recommended doses have been defined in children for TMZ (200 mg/m2/d x 5 d) and TPT (1.5 mg/m2/d x 5 d). Some preclinical and clinical studies have shown activity of both drugs in some pediatric cancers. Nevertheless, the association of the two drugs has never been evaluated. The study aims to determine Maximum Tolerated Dose and dose limiting toxicities of each drug when associated and to assess efficacy of the combination.
Researchers at the National Cancer Institute and the University of Minnesota have followed a nationwide cohort of 146,022 radiologic technologists since 1982 (Boice 1992; Doody 1998; Mohan 2003; Sigurdson 2003). This is one of the largest cohorts of medical radiation workers studied to date (Yoshinaga 2003)and the only one with substantial numbers of women (73% female), extensive covariate data, both incident and death outcomes, and estimated occupational radiation doses. The overall study objectives are to: quantify radiation dose-response for cancers of the breast, thyroid, and other radiogenic sites; assess cancer risks associated with genotypic, phenotypic, or other biologically measurable factors; and determine if genetic variation modifies radiation-related cancer risks. More than 110,000 technologists completed at least one of three comprehensive questionnaire surveys administered over the last 20 years and 18,500 are deceased. The First Survey was mailed during 1984-1989 to 132,454 known living radiologic technologists, of whom 90,305 (68%) completed the survey (Boice 1992). The Second Survey was mailed during 1993-1998 to 126,628 known living technologists, of whom 90,972 (72%) completed the questionnaire (Sigurdson2003). Both surveys included detailed questions about employment as a radiologic technologist, family history of cancer, reproductive history, height, weight, other cancer risk factors (such as alcohol and tobacco use), history of personal diagnostic and therapeutic medical radiation procedures, and information on cancer and other health outcomes. A third follow-up of this cohort was recently completed. During 2003-2005, the Third Survey was mailed or administered by telephone to 101,694 living cohort members who had completed at least one of the two previous surveys; 73,838 technologists (73%) completed the survey. This questionnaire elicited information on medical outcomes to assess radiation-related risks, detailed calendar-specific employment data to refine the occupational ionizing radiation dose estimates, and behavioral and residential histories for estimating lifetime ultraviolet (UV) radiation exposures. The large number of women with estimates of cumulative radiation dose to specific organs (e.g. breast) (Simon 2006; see Figure 7 and Table 9) offers at are opportunity to study effects of low-dose radiation exposure on breast and thyroid cancers, the two most sensitive organ sites for radiation carcinogenesis in women.. We are not aware of any other study population in which both quantified radiation doses and biospecimens are available for individuals with protracted low-dose ionizing radiation exposures. Incorporation of assessment of the role of genetic polymorphisms and molecular variants in DNA repair and other genetic pathways that may be functionally important in radiation carcinogenesis would provide initial results on the possible role of genetic factors in the cancer-radiation relationship. Because large numbers of women are exposed to ubiquitous low-dose radiation from occupational, medical, and environmental sources, the presence of radiation-sensitive genetic variants that influence the risk of breast and other cancers would have important public health implications.
