Active clinical trials for "Gallbladder Neoplasms"

Background: - Chile has the highest diagnosis and death rates of gallbladder cancer in the world. Gallbladder cancer is also the leading cause of cancer death in Chilean women. High rates of gallstones and obesity, as well as genetic concerns, may explain these high rates. Researchers want to study gallbladder cancer in more depth in Chile. A small study must be done to see if a full-scale study is feasible. Objectives: - To test the methods and procedures of a small-scale study of gallbladder cancer in Chile. Eligibility: Individuals at least 18 years of age who have gallbladder cancer or gallstones, or are healthy control volunteers. Participants will be recruited from four clinical centers in Chile. Design: Participants will be screened with a physical exam and medical history. Because gallbladder cancer has a high fatality rate, family members may be asked to provide additional medical history information if study participants die or become too ill to provide this information. Participants will provide blood, urine, stool, hair, fingernail, and saliva samples. Gallstones, bile, and tissue samples will be collected from those who have gallbladder removal surgery. Normal and tumor tissue samples will be collected as needed. Treatment will not be provided as part of this protocol. This is a data collection study only.

Background: The gallbladder is a small organ below the liver. Gallbladder cancer is a leading cause of cancer death among women in Chile. Chile also has among the highest rates of gallbladder cancer and death in the world. Researchers in a high-risk region of Chile want to find out more about this type of cancer. They especially want to know how inflammation affects the way it develops. Objective: To better understand the causes of gallbladder diseases and factors that may be associated with them. Eligibility: Women ages 50 74 with gallbladder cancer who are covered by the Chilean national health system. Other people over age 21 with gallbladder disease. Healthy adults over age 21. Design: Participants may be screened with an ultrasound. They may be asked questions about their health. Participants will have an ultrasound of the abdomen. This can be done at the study clinic or in the hospital or at home. The ultrasound uses sound waves to take pictures of the gallbladder. Participants will have a physical exam. Participants will have their mouths looked at for tooth loss, dentures, and gum redness. Participants will give a blood sample or saliva sample. Participants will be asked for access to their medical history. They may be asked to allow researchers to keep any samples taken during gallbladder surgery. Participants will answer questions about their medical history. This will include illnesses, surgeries, medicine use, and family history. It will also include diet and lifestyle habits, such as places where they have lived and worked. Some participants will have 3 follow-up visits over 6 years. ...

We hope to determine the importance of different genes (including B receptors) in anthracycline-induced cardiomyopathy. This has important benefits to patients exposed to anthracyclines, as this could help determine whether certain individuals have increased susceptibility to cardiac injury.

RATIONALE: Diagnostic procedures, such as visceral lymphatic mapping using isosulfan blue, may help find cancer of the pancreas, colon, stomach, small intestine, or gallbladder and find out how far the disease has spread. PURPOSE: This clinical trial is studying the side effects and how well visceral lymphatic mapping using isosulfan blue works in patients with cancer of the pancreas, colon, stomach, small intestine, or gallbladder.

Alpha-fetoprotein (AFP) can become elevated in hepatocellular carcinoma (HCC), yolk sac tumors and other malignant tumors of various organs. Herein, the investigator present a case of AFP-producing gallbladder carcinoma with signet ring cells successfully treated with laparoscopic whole-layer cholecystectomy.

RATIONALE: Gathering information about patients' quality of life during radiation therapy for cancer may help doctors plan the best treatment. PURPOSE: This randomized clinical trial is studying quality of life in patients undergoing radiation therapy for primary lung cancer, head and neck cancer, or gastrointestinal cancer.

The purpose of the study is to determine whether palliative biliary stenting improves the quality of life, of gallblader cancer patients, who present with hilar block and obstructive jaundice.

The purpose of the study is to establish a repository of human bile as a resource for studies evaluating molecular predictors of biliary cancer risk.

To determine whether biomarkers assessed in blood samples can be used to detect individuals at risk for developing blood clots or worsening of their underlying disease. The ultimate goal of the study is to identify key biomarkers derived from blood that are most characteristic and informative of individuals who will go on to develop a clotting complication.

This case-control study matched by age and sex was performed to evaluate the region specific risk factors for gallbladder cancer in Jeju island, Korea.
