Tumor Cell and DNA Detection in the Blood, Urine, and Bone Marrow
Patients with resectable solid primary cancers and even limited number of metastases are potentially curable. However, most patients develop recurrences despite surgery. Also, early detection of lung cancer with low dose CT screening may cure patients at an early stage. Circulating and disseminated tumor cell (CTC/DTC) and circulating cell-free (cf) DNA isolation from the blood, urine and bone marrow will increase understanding of cancer spread and advance knowledge to develop individualized therapies and improve screening.

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.

Stomach-Partitioning Versus Conventional Gastrojejunostomy for Malignant Gastric Outlet Obstruction: A Multicenter Randomized Controlled Trial
Gastric outlet obstruction (GOO) complicates locally advanced or metastatic gastric cancer and severely impairs oral intake, nutritional status, and quality of life. Conventional gastrojejunostomy (CGJ) effectively relieves the obstruction but is associated with a high incidence of delayed gastric emptying (DGE), which delays the resumption of oral intake and the initiation of systemic anticancer therapy. Stomach-partitioning gastrojejunostomy (SPGJ) isolates the tumour-bearing distal stomach from the alimentary tract and has been suggested, in retrospective studies, to reduce the incidence of DGE. However, no randomized evidence is currently available, and the comparative safety and efficacy of SPGJ and CGJ remain uncertain. This multicenter, randomized, open-label, blinded-outcome-assessment trial will randomly assign 80 participants with unresectable distal gastric adenocarcinoma complicated by GOO, in a 1:1 ratio, to undergo either SPGJ or CGJ. The primary endpoint is the incidence of postoperative DGE within 30 days after surgery.

Distance-Based Exercise to Preserve Function and Prevent Disability
This clinical trial studies whether an exercise program can be successfully delivered to patients receiving treatment for cancer through virtual sessions and allow patients to exercise in their own home. Treatments for cancer can cause side effects such as fatigue and loss of strength. These side effects can make it difficult to work, take care of family, and do other things the patient wants to do. Preliminary research shows that exercise can help prevent some of these side effects, but it can be more difficult to start an exercise program when a patient is receiving cancer treatment. The exercise program in this study is delivered through telehealth (TH) video calls. The TH sessions are delivered by trained staff that supervise resistance exercises. The trained staff also provide guidance to the patient on completing unsupervised aerobic sessions on their own. This may be a successful way to deliver an exercise program and make it easier for cancer patients to exercise in their own home during treatment.
