Active clinical trials for "Gastrointestinal Neoplasms"

Phase II trial to study the effectiveness of romidepsin in treating patients who have locally advanced or metastatic neuroendocrine tumors. Drugs used in chemotherapy, such as romidepsin, work in different ways to stop tumor cells from dividing so they stop growing or die.

RATIONALE: Radiation therapy uses high-energy x-rays and other sources to damage tumor cells. Giving radiation therapy in different ways may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of indium In 111 pentetreotide in treating patients who have refractory cancer.

This study will evaluate the efficacy and safety of alectinib in participants with Anaplastic Lymphoma Kinase (ALK)-positive locally advanced or metastatic solid tumors other than lung cancer.

Background: - Mithramycin is a drug that was first tested as a cancer therapy in the 1960s. It acted against some forms of cancer, but was never accepted as a treatment. Research suggests that it may be useful against some cancers of the chest, such as lung and esophageal cancer or mesothelioma. Researchers want to see if mithramycin can be used to treat these types of cancer. Objectives: - To see if mithramycin is safe and effective against different chest cancers. Eligibility: - Individuals at least 18 years of age who have lung, esophagus, pleura, or mediastinum cancers. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Imaging studies and tumor tissue samples will be used to monitor the cancer before treatment. Participants will receive mithramycin every day for 7 days, followed by 7 days without treatment. Each 14-day round of treatment is called a cycle. Treatment will be monitored with frequent blood tests and imaging studies. Participants will continue to take the drug for as long as the side effects are not severe and the tumor responds to treatment.

Neuroendocrine tumors (NETs) and cancers that originate from the gastrointestinal tract can be resistant to standard chemotherapy and often metastasize to the liver. Lanreotide (Somatuline® Depot) Injection and Yttrium-90 microspheres (SIR-Spheres®) each have FDA approval to treat patients with metastatic NETs. The purpose of this study is to determine if treatment for patients with NETs can be optimized by combining these therapies.

Registration of patients after gastrointestinal cancer radical surgery, including the information of treatments, recurrence & metastasis, adverse events,etc.

Background: Exome sequencing can identify certain gene mutations in a person's tumor. This can then be used to create cancer treatments. In this study, researchers will make a treatment called a messenger ribonucleic acid (mRNA) vaccine. The vaccine might cause certain tumors to shrink. Objective: To see if the mRNA vaccine is safe and can cause metastatic melanoma or epithelial tumors to shrink. Eligibility: People 18-70 years old with metastatic melanoma or epithelial cancer Design: Participants will be screened under protocol 99-C-0128. Participants will provide samples under protocol 03-C-0277: Participants will provide a piece of their tumor from a previous surgery or biopsy. Participants will have leukapheresis: Blood is removed through a needle in one arm and circulated through a machine that takes out the white blood cells. The blood is then returned through a needle in the other arm. Participants will have many tests: Scans and x-rays Heart and lung function tests Blood and urine tests Participants will receive the mRNA vaccine every 2 weeks for up to 8 weeks. They will get the vaccine as an injection into the upper arm or thigh. They may receive a second course of vaccines if the study doctor determines it is needed. Participants will have follow-up visits approximately 2 weeks after their final vaccine, then 1 month later, then every 1-2 months for the first year, and then once a year for up to 5 years. Each visit may take up to 2 days and include: Physical exam Blood tests Scans Leukapheresis at the first visit

Background: Exomes are the parts of deoxyribonucleic acid (DNA) that make proteins. Researchers are finding a way to read the letters in the exome. Incorrect letters are called mutations. Tumors contain specific mutations. Researchers can find these mutations in tumors to make treatments. Researchers want to use pieces of participants tumors to find the tumor-specific mutations. They also will take participants white blood cells to make a vaccine that they hope will shrink the tumors. Objectives: To see if dendritic vaccine tumor-fighting cells are safe and can cause certain cancer tumors to shrink. Eligibility: Adults ages 18-70 who have metastatic melanoma or metastatic epithelial cancer Design: The first part of this study was done under protocol 03-C-0277. In that study, white blood cells and pieces of participants' tumors were taken to make a vaccine. In this study, participants will get a vaccine every 2 weeks for 8 weeks. It will be given both in a vein and under the skin. At each visit, participants will have a physical exam and have blood taken. They will talk about any side effects they have. After treatment ends, participants will have many follow-up visits for the first year, then once each year after that. Visits will last up to 2 days each. They will include lab tests, imaging studies, and a physical exam. Blood will be taken at each visit. At the first follow-up visit, participants may have leukapheresis, which they also had as part of protocol 03-C-0277. Participants may not have to return to the Clinical Center for these visits.

Background: - Some people with gastrointestinal or ovarian cancer also have ascites. That is free fluid built up in the abdomen. Researchers want to see if a new drug can affect some of the immune cells in the ascites. This may also treat the cancer. Objective: - To look at the immune markers the ascites of people with gastrointestinal or ovarian cancer. Eligibility: - Adults age 18 and older with a malignancy of the gastrointestinal tract (GI) tract or metastatic ovarian cancer. As a result, they have ascites in the abdomen. Design: Participants will be screened with: Medical history, physical exam, and blood tests. Echocardiogram: sound waves make images of the heart. Electrocardiogram: measures electrical activity of the heart. Paracentesis: a needle will be inserted in the abdomen and will remove some of the ascites fluid. They may have a tumor biopsy. Participants will get AZD9150 through a vein for 3 hours. They will get this 6 times in cycle 1 and 4 times all other cycles. Each cycle is 28 days. Each cycle, participants will: Have a physical exam. Have blood tests weekly. Be asked about how they feel and any medicines they are taking. After every 2 cycles (about every 2 months), participants will have scans and x-rays of their tumor. Participants will have paracentesis 2 more times during the study. They will have another echocardiogram. At the end of therapy, participants will have a physical exam and blood tests. They will be asked about how they feel and any medicines they are taking.

RATIONALE: Drugs used in chemotherapy, such as doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Infusing doxorubicin beads into the liver, and blocking blood flow to the tumor, may keep doxorubicin near the tumor and kill more tumor cells. PURPOSE: This clinical trial is studying the side effects of doxorubicin beads and to see how well they work in treating patients with unresectable liver metastases from neuroendocrine tumors.
