Phase II Randomized Trial of Bethesda Protocol Compared to Cambridge Method for Detection of Early Stage Gastric Cancer in CDH1 Mutation Carriers

Background: Some people have a mutation in the CDH1 gene that is known to lead to stomach cancer. They are advised to get regular endoscopies with biopsies even if their stomach appears normal. The endoscopy method currently used is called the 'Cambridge Method.' Researchers want to test a new method called the 'Bethesda Protocol.' Objective: To compare the Cambridge Method and Bethesda Protocol and find out which is more efficient in catching early signs of cancer. Eligibility: Adults age 18 and older who have a mutation in the CDH1 gene. Design: Participants will be screened with a review of their medical history, medical records, and physical status. Participants will be put into group 1 (Bethesda Protocol) or group 2 (Cambridge Method). Participants will have a physical exam. They will have endoscopy. For this, they will be put under general anesthesia. They will wear compression cuffs around their legs to prevent blood clots. A lighted tube will be inserted into their mouth and go down to their stomach. For group 1 participants, 88 pieces of tissue will be taken from 22 areas of their stomach. For group 2 participants, 30 pieces of tissue will be taken from 6 areas of their stomach. Then group 2 will be injected with a contrast dye. A microscope will be inserted, and more samples will be taken. About 14 days later, participants will have a follow-up visit or phone call. They may give stool samples every 3 to 6 months for 12 months for research purposes. Participants may have another endoscopy 6-18 months later. ...

Intraperitoneal and Intravenous Paclitaxel Chemotherapy With Oral Capecitabine for Gastric Adenocarcinoma With Peritoneal Carcinomatosis

Background: Three-fourths of people diagnosed with gastric cancer will die from it. Researchers want to see if giving cancer drugs in a new way can help people live longer and delay the time it takes for the cancer to grow. Objective: To find a better way to treat advanced stomach cancer. Eligibility: People ages 18 and older with stomach cancer that has spread throughout their belly. Design: Participants will be screened with: Medical history Physical exam Blood, urine, and heart tests Scans Cancer sample: If they do not have one, they will have a biopsy. Tests of performance of normal activities Dietary assessment Participants will have a laparoscopy. Small cuts are made into their abdomen. A thin camera with a light is inserted. Small instruments are used to take biopsies. This will be repeated during the study to monitor the cancer. During the first laparoscopy, a port with a catheter attached will be put into the abdomen. Participants may also have an endoscopy: A thin tube with a camera is inserted through the mouth and into the stomach. The tube collects samples to monitor the cancer. Participants will get paclitaxel every 3 weeks through the abdominal port and through a small plastic tube in an arm vein. They will also take capecitabine by mouth twice daily for the first 15 days of a 21-day cycle. After participants finish 3 cycles, they will have scans to see how they are doing. They may get another course of therapy. Participants will have visits every 3 weeks during treatment. Then they will have follow-up visits for 5 years. Then they will keep in touch with researchers for the rest of their life.

Heated Intraperitoneal Chemotherapy and Gastrectomy for Gastric Cancer With Positive Peritoneal Cytology

Background: Gastric cancer is a common and serious cancer. Standard treatment is chemotherapy drugs. Researchers want to see if a new treatment helps. It is surgical removal of the cancer and heated chemotherapy delivered to the abdominal cavity called HIPEC. Objective: To test if surgical removal of tumors plus heated intraperitoneal chemotherapy can improve survival in people with gastric cancers. Eligibility: People ages 18 and older with gastric cancer who can have most tumors surgically removed Design: Participants will be screened with: Medical history Physical exam Blood, urine, and heart tests Scans Tissue sample from previous surgery Endoscopy with biopsy: A tube with a camera goes through the mouth and into the stomach. It and takes a sample of stomach tissue. Participants might may get medicine to make them drowsy. Laparoscopy: Small cuts are made in the abdomen. A thin tube with a light and camera is inserted into the abdomen. Participants sleep through the procedure. Participants will stay in the hospital. They will have: Surgery to remove as many tumors as possible. HIPEC for 60 minutes: Two thin tubes are put into the abdomen. Two chemotherapy drugs are given through one tube. They are drained out through another at a temperature a few degrees above normal body temperature. Another drug is given in a vein. Recovery for 7-21 days: Participants will have tubes in their stomach and bladder and IVs for a few days. They will get pain medicine, IV fluids, antibiotics, and blood transfusions as needed. Participants will have visits every few months for 3 years, then one a year. Visits include physical exam, blood tests, and scans. They also include dietary assessment and questions.

Surgery in Gastrointestinal Stromal Tumors (GISTs) for Treatment, Tumor Modeling, and Genomic Analysis

Objective: To follow people with GISTs and collect tumor tissue so that it can be studied in the lab. Eligibility: People age 6 and older who have a GIST. Design: Participants will be screened with a review of their medical records and samples. Participants will enroll in 1 other NIH study, and may be asked to enroll in 2 other optional NIH studies. Participants will have a medical history and physical exam. Data about how they function in their daily activities will be obtained. Participants may speak with a genetic counselor. They may have genetic testing. Participants will give blood samples. They may have a cheek swab. For this, small brush will be rubbed against the inside of the cheek. Participants may have a computed tomography (CT) scan of the chest, abdomen, and pelvis. Or they may have a CT scan of the chest and magnetic resonance imaging (MRI) of the abdomen and pelvis. Participants will be monitored every 6-12 months at the NIH Clinical Center, for up to 10 years before having surgery. If they need surgery, it will be performed at the NIH. Then, they will be monitored every 6-12 months, for up to 5 years after surgery. If a participant has surgery, tumor tissue samples will be taken. If a participant does not need surgery, their participation will end after 10 years. If they have surgery, the 5-year monitoring period will restart after each surgery. ...
