Nutrition Intervention Trials in Linxian Follow-up Study
Two large, nutritional intervention trials were conducted in Linxian, China between 1985-1991. These trials tested the effect of multiple vitamins and minerals in the prevention of esophageal cancer in a population with the highest known rate for this disease in the world. Results from the trials showed that Beta-carotene + Vitamin E + selenium reduced total mortality, total cancer mortality, and stomach cancer incidence and mortality. Multivitamins/minerals also showed reduction in premalignant lesions. Preliminary follow-up data obtained for the time period after cessation of intervention in 1991 suggests that the observed benefit for total and cancer mortality is reduced but that the benefit for stomach cancer remains. The objectives of the follow-up study are: (1) to continue to determine cancer incidence and all causes of mortality in trial participants after intervention to permit examination of potential effects of the interventions on total and cause-specific mortality and cancer incidence in the post-intervention period; (2) to conduct a cross-sectional nutritional survey in a subsample of living trial participants to evaluate their nutritional status, asses the validity of dietary questionnaires, and relate neurologic status to vitamin B12 plasma levels; (3) to collect a blood sample from all living trial participants to permit further etiologic investigations of genetic and environmental hypotheses; and (4) to perform nested case-control studies of selected genetic and environmental hypotheses. To accomplish the objectives of the follow-up study, we will: (1) determine updated vital status and cancer status data on all trial participants via monthly checks of village doctor records and quarterly checks of the Linxian Cancer Registry; conduct a Vital/Cancer Status Interview Survey among all (n-34,000 trial participants (or their surrogates); identify, collect, and store all available diagnostic materials for trial participants identified as having developed cancer or died with cancer during the follow-up period; (2) conduct a Nutritional Survey on a subsample (n-1000) of living trial participants that will include (a) a physical exam and brief medical history, (b) a neurologic history, (c) a cognitive function exam, (d) a hair/mouth skin exam, (e) a neurological exam, (f) a nutritional questionnaire, and (g) collection of a blood sample for hematologic/biochemical analyses; (3) conduct a Blood Collection Survey of all living trial participants (n-23,000) to obtain (a) a physical exam and brief medical history and (b) a single 10-ml blood sample for separation and preservation as WBCs (both viable and nonviable), RBCs, and plasma for genetic (e.g., xenobiotic polymorphisms) and environmental (e.g., plasma ascorbic acid) hypothesis testing; and (4) perform Nested Case-Control Studies of selected genetic and environmental hypothesis related to the etiology and prevention of esophageal cancer and stroke. These will be done using serum from the new cancer and stroke cases (-2500) and controls (-2500) previously identified from 1991-1996, as well as using new cancer and stroke cases and controls for the period 1996-2004 (-9000). The followup for endpoints will continue monthly for an additional 5 years (through the year 2003). The Nutritional Survey and Blood Collection Survey will be conducted in the spring of 1999. The Nested Case-Control studies will be performed annually beginning in 2000, and the Vital/Cancer Interview Survey will be conducted in the Spring of 2001....

Ovarian-Sparing Adaptive Radiotherapy in Young Adult Women
Female patients with early onset (\<50 years old) pelvic malignancies such as uterine and rectal cancers are rising in incidence, which often requires pelvic radiation; many of these patients are premenopausal and at a high risk of premature ovarian failure from radiotherapy. Premature ovarian failure carries significant cardiac, musculoskeletal, sexual, and psychosocial morbidity. Ovarian transposition carries variable success rates, is not readily accessible to the general population, and can still be at risk of clinically significant radiotherapy doses. There is an unmet need for innovative techniques to protect ovarian function.

18F-Fibroblast Activation Protein Inhibitor ([18F]FAPI-74) PET Imaging for Cancer Detection
Background: Fibroblast-activation protein (FAP) is an enzyme that appears in high numbers in cancer-associated fibroblasts of certain cancer types. \[18F\]FAPI-74 is a new PET (positron emission tomography) tracer, a substance that is injected into a person s body before an imaging scan. Researchers believe that \[18F\]FAPI-74 PET imaging may be able to visualize cancer more effectively than the approved tracers. If so, the new tracer would make it easier to find FAP-positive tumors in the body. Objective: To see if \[18F\]FAPI-74 PET scan is as good or better than other imaging methods for detecting certain cancers. Eligibility: People aged 18 years or older with one of these cancer types: pancreatic ductal adenocarcinoma (PDAC), cholangiocarcinoma, hepatocellular carcinoma (HCC), gastric cancer, bladder cancer, ovarian cancer, pheochromocytoma/paraganglioma (PPGL), small cell lung cancer (SCLC) or extrapulmonary neuroendocrine cancer (EP-NEC), mesothelioma or sarcoma. Participants must be scheduled or intended to receive treatment for cancer. Design: Participants will have 2 baseline scans: an \[18F\]FAPI-74, and the approved tracer \[18F\]-FDG. The \[18F\]FAPI-74 will be infused through a needle inserted into a vein. About 1 hour later, the participant will undergo imaging. Within 1 week, participants will undergo the same scanning procedures with the approved tracer. If the baseline scan with \[18F\]FAPI-74 shows the tumor(s), scans with this tracer will be repeated when their regular treatment regimen calls for scans again. If the scan with the regular FDG also show tumors, this scan will be repeated within the same week as the repeated \[18F\]FAPI-74 scan. If \[18F\]-FAPi PET scan shows no tumor(s), scans will not be repeated. If the participant's cancer progresses within 2 years, scans may be repeated. Follow-up calls will continue for 2 years.
