Active clinical trials for "Digestive System Neoplasms"

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.

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.

The purpose of this study is to define the recommended dose of BMS-582664 that could be safely combined with 5-fluorouracil, leucovorin, and irinotecan (FOLFIRI) or 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) chemotherapy regimens in patients with advanced gastrointestinal malignancies and to evaluate the safety profile, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of these combinations.

Tenatumomab is a Sigma-Tau developed new anti-Tenascin antibody. It is a murine monoclonal antibody directed towards Tenascin-C. By means of this antibody, Tenascin-C expression was studied on a commercial tissue array slides each carrying malignant breast, colorectal, lung, ovarian or B and T cell Non-Hodgkin Limphoma tissue sections. All these cancers type showed positivity to Tenascin-C between the 64% and 13.3%. Consequently, Sigma-tau is exploring the use of the 131I-labeled Tenatumomab for anti-cancer radioimmunotherapy.

This study evaluates the efficacy of the endoscopic hemostatic powder for the treatment of bleeding from malignant lesions of the upper GI tract. Half of participants will receive hemostatic powder and half will be submitted to standard treatment.

The primary objective of this study is to assess the overall survival (OS) of oral linifanib given as monotherapy once daily (QD) compared to sorafenib given twice daily (BID) per standard of care in subjects with advanced or metastatic HCC.

The purpose of this study is to compare the similarities and differences of 99mTc-FAPI quantitative SPECT/CT and 68Ga-FAPI PET/CT in the diagnosis and staging of gastrointestinal tumors, and clinical diagnosis and economic value of 99mTc-FAPI quantitative SPECT/CT for the gastrointestinal tumors.

Bone metastasis causes bone destruction and skeletal related events (SRE) including compression fracture, hypercalcemia, and spinal cord compression. Therefore, palliative treatments for pain control and local control have become important and multidisciplinary multimodality approach is needed for treatment of bone metastasis. The efficacy of radiotherapy (RT) for bone metastasis is well known. And the results that bisphosphonate decreases SRE in patients with solid tumor and multiple myeloma reported. In previous retrospective reports, the combination of local RT and systemic bisphosphonate was more effective than RT alone. Therefore, Investigators designed a phase II study to evaluate the efficacy of RT in combination with zoledronic acid on pain relief and the safety of RT in bone metastasis patients with gastrointestinal tumors.
