Filter by:Hepatobiliary tumors have a poor prognosis and high individual heterogeneity, so it is of great significance to find important prognostic markers and then screen out specific subgroups of people; meanwhile, chronic hepatitis, cirrhosis, and healthy control participants also need to show the evolution of tumors and discover specific diagnostic markers as a control group. Moreover, targeted therapy and immunotherapy make cancer treatment enter a new field, but only part of patients achieve response rates and reach clinical benefit. However, these drugs are expensive and can cause treatment-related adverse events. Therefore, reliable biomarkers identification is needed to help predict the response to these treatment options in order to screen patients with better responsiveness and avoid wasting money. Multi-omics research can reveal the characteristics of hepatobiliary tumors more deeply and find meaningful therapeutic targets. Therefore, 450 patients at least 18 years of age with hepatobiliary tumors were included in this study.
RATIONALE: A tethered capsule endoscope may be as effective as standard sedated endoscopy of the esophagus, stomach, and duodenum in screening for Barrett esophagus. PURPOSE: This phase I/II trial is studying how well a tethered capsule endoscope works in screening participants for Barrett esophagus.
RATIONALE: Studying samples of sputum and tissue in the laboratory from patients with dysplasia or cancer may help doctors identify and learn more about biomarkers related to cancer. It may also help the study of cancer in the future. PURPOSE: This laboratory study is looking at biomarkers in patients with respiratory tract dysplasia or lung cancer, head and neck cancer, or aerodigestive tract cancer.
RATIONALE: Studying samples of tissue, blood, urine, stool, and other biological fluids from patients with cancer and from healthy volunteers undergoing colonoscopy or endoscopy may help doctors identify and learn more about biomarkers related to cancer. PURPOSE: This research study is looking at gastrointestinal biomarkers in tissue and biological fluid samples from patients and participants undergoing colonoscopy, endoscopy, or surgery.
RATIONALE: Drugs used in chemotherapy, such as carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs such as cidofovir may make tumor cells more sensitive to radiation therapy. Giving cidofovir together with radiation therapy and chemotherapy may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of cidofovir in treating patients with stage IB, stage II, stage III, or stage IVA cervical cancer who are receiving chemotherapy together with radiation therapy.
RATIONALE: Giving chemotherapy, such as fludarabine, busulfan, and cyclophosphamide, together with antithymocyte globulin before a donor stem cell transplant helps stop the growth of cancer and abnormal cells. Giving chemotherapy before or after transplant also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer and abnormal cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well stem cell transplant works in treating patients with hematological cancer or other disorders.
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. Erlotinib may keep esophageal cancer from forming in patients with Barrett esophagus by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying how well erlotinib works in treating patients with Barrett esophagus.
RATIONALE: Learning about how often heartburn and other risk factors occur in brothers and sisters and other family members of patients with Barrett's esophagus may help identify other individuals at risk and identify genes for Barrett's esophagus. PURPOSE: This clinical trial is studying genes for Barrett's esophagus in brothers and sisters.
