Filter by:This is a prospective cohort study of diet and cancer in relation to several major cancers, especially breast, prostate, and colorectal malignancies. The cohort comprises 50-69 year-old male and female members of the American Association of Retired Persons (AARP). In 1995-6 we mailed baseline questionnaires to 3.5 million AARP members. Over 615,000 AARP members responded, with over 540,000 providing adequate dietary data. Preliminary analysis indicates that the cohort, both men and women, has the desired wide distributions of percent calories from fat, dietary fiber, fruits and vegetables, and red meat. Approximately 330,000 of the initial respondents (with satisfactory data) returned a second questionnaire containing questions on exposures not assessed in the first instrument. In terms of field activities, the study has been relatively quiescent over the past year. At the end of the five-year period of observation, we will mail to cohort members a brief follow-up questionnaire primarily targeted to endpoint assessment. (Because of cancer registry lag-time, we do not expect to mail this questionnaire until early 2002.) Follow-up will be largely passive, through established state registries. The initial questionnaire mailing will be to AARP members in those states selected on the basis of having registries with adequate coverage and quality. We will use active follow-up, with record retrieval, for the small percentage of cohort members who have moved out of the cancer registry areas. The buccal cell collection pilot study has been completed; over 50% of those pilot study partricipants who had completed the baseline and risk factor questionnaires returned buccal cell speciments. Preliminary data from a pilot study of the end point ascertainment procedure indicate that cohort incidence rates for major cancers, determined from registry data, are consistent with SEER rates.
The Division of Cancer Preventionl (DCP, formerly DCPC), under extramural contracts to 10 U.S. clinical centers, is evaluating the effectiveness of screening for prostate, lung, colorectal and ovarian cancer (The PLCO Trial). In 1996 the NCI Executive Committee approved the expansion of the PLCO Trial to collect additional materials and to conduct additional studies. About, 74,000 men and 74,000 women, aged 55-74 years, have been randomized on a 50/50 basis into screening or usual care arms. Additional blood is collected from screened subjects and saliva for buccal cells from control subjects. Pathologic tissues are obtained for selected cases that develop cancer or selected related diseases (e.g. colon polyps, benign prostatic hyperplasia). Additional questionnaire-based risk and disease-related information is also collected, withconfirmation of disease status from medical records. Genetic, biochemical and questionnairebasedrisk information will be related to the development of cancer and other diseases in this population. Volunteers who provide samples for these studies will not routinely receive their individual results from the Additional Investigation. Subjects requesting such information, however, will be provided their test results. In 2009 the NCI Executive Committee approved the Extended Follow-up of subjects beyond the original 13-year follow-up period. Participants will be reconsented for the release of records to a single NCI-Designated Central Data Collection Center (CDCC), which will administer the annual mailings containing the annual study update questionnaire and a brief (1-2 page) risk factor questionnaire. Individuals who do not consent to release their identifiers to the CDCC will be followed up passively through linkage to state cancer registries and the National Death Index. This protocol Review Application is for (1) the collaboration of intramural scientists in the Division of Cancer Epidemiology and Genetics (DCEG) in the Additional Studies and (2) the coordination, in collaboration with DCP, of the Extended Follow-up.
The purpose of this study is to determine the effectiveness and safety of PROCRIT (Epoetin alfa) at a starting dose of 60,000 Units (U) once every week (QW) to a target hemoglobin (Hb) of 12 g/dL (Initiation Phase), followed by a dose of 80,000 Units once every three weeks (Q3W) to maintain a Hb range of 11.5 to 12.5 g/dL (Maintenance Phase) in cancer patients receiving chemotherapy.
The purpose of this study is to determine the effectiveness and safety of epoetin alfa at a starting dose of 60,000 Units (U) once every week (QW) to a target hemoglobin (Hb) of 12 g/dL (Initiation Phase), followed by a dose of 60,000 U once every other week (Q2W) to maintain a Hb range of 11.5 to 12.5 g/dL (Maintenance Phase) in cancer patients receiving chemotherapy.
This trial is conducted in Oceania. A phase 2a study to assess the effect on tumor size. At least 14 to a maximum of 40 patients, who have not previously received treatment for their stage IV disease, will be treated for 6 weeks. IL-21 will be administered intravenously.
The purpose of this study is to assess the safety and tolerability of the multiple receptor tyrosine kinase (RTK) inhibitor (including EGFR, VEGFR2, ErbB2, and EphB4) XL647 when given orally daily to adults with advanced solid tumors.
The aim of this study is to determine the prevalence of asymptomatic lower extremity DVT detected by US-Doppler and procoagulant microparticles in a selected group of cancer patients suffering from an advanced stage of the disease. An attempt will be made to determine whether there is a correlation between this prevalence and various clinical and laboratory parameters.
CRLX101 is a nanopharmaceutical comprised of the chemotherapeutic camptothecin (CPT) conjugated to a linear, cyclodextrin-based polymer. CRLX101 is designed to increase the exposure of tumor cells to CPT while minimizing side effects. OBJECTIVES: • Determine the safety, toxicity, and the maximum tolerated dose (MTD) of CRLX101 when administered intravenously to subjects with advanced solid tumors.
The purpose of this study is to determine what effects Esomeprazole (Nexium) has on increasing or decreasing the amount of oral taxane in the blood, and to determine the safety of oral taxane and effect of oral taxane on the cancer.
This study is intended to investigate the recommended dose of alvimopan in doses 0.25mg/day (0.25mg, OD), 0.5mg/day (0.25mg, BID) or 1mg/day (0.5mg, BID) or placebo for 3 weeks in patients who receive opioids for the management of cancer pain and develop constipation, by giving overall consideration to the efficacy and safety data in each treatment group. Also, efficacy and safety data of alvimopan in the recommended dose group will be compared with those of placebo and to confirm alvimopan's safety and efficacy.
