Filter by:This study was designed to evaluate the efficacy and safety of Extimia® (INN - empegfilgrastim) in reducing the frequency, duration of neutropenia, the incidence of febrile neutropenia and infections caused by febrile neutropenia in patients with High and "Gray Zone" Risk Reccurrence Breast Cancer, Gastointestinal Cancers and Gynecological Malignancies
The purpose of this study is to determine whether AGuIX (Activation and Guidance of Irradiation by X-ray) gadolinium-based nanoparticles make radiation work more effectively in the treatment of patients with brain metastases that are more difficult to control with stereotactic radiation alone.
Background: Cytoreductive surgery (CRS) removes tumors in the abdomen. HIPEC is heated chemotherapy that washes the abdomen. CRS and HIPEC may help people with peritoneal carcinomatosis. These are tumors that have spread to the lining of the abdomen from other cancers. Researchers think they can improve results of CRS and HIPEC by choosing the chemotherapy drugs used in HIPEC. Objective: To see if HIPEC after CRS can be improved, by testing different chemotherapy drugs, using a model called the SMART (Sample Microenvironment of Resected Metastatic Tumor) System. Eligibility: Adults ages 18 and older who have peritoneal carcinomatosis that cannot be fully removed safely with surgery. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Computed tomography (CAT) scan Other imaging scans, as needed Electrocardiogram (EKG) Tumor biopsy, if needed Laparoscopy. Small cuts will be made in the abdomen. A tube with a light and a camera will be used to see their organs. Some screening tests will be repeated in the study. Participants will enroll in NIH protocol #13C0176. This allows their tumor samples to be used in future research. Participants will have CRS. As many of their visible tumors will be removed as possible. They will also have HIPEC. Two thin tubes will be put in their abdomen. They will get chemotherapy through one tube. It will be drained out through the other tube. They will be in the hospital for 7-21 days after surgery. Participants will give tumor, blood, and fluid samples for research. They will complete surveys about their health and quality of life. Participants will have follow-up visits over 5 years.
The discovery of cell-free circulating tumor DNA (crDNA) in blood and the maturation of technologies for ctDNA analysis have presented an attractive opportunity for minimally invasive "liquid biopsy" genomic diagnostics. The investigators plan to perform EUS-guided portal vein and hepatic vein aspiration in GI cancers patients. The aim of the current study is thus to examine the concentration of ctDNA in portal vein (EUS-guided PVA), hepatic vein (EUS-guided HVA) and peripheral blood to understand the first pass effect of the liver with gastrointestinal (GI) cancers, and the possibility of using ctDNA as a marker for preoperative staging, restaging after neoadjuvant chemotherapy, and monitoring for recurrence.
This study assesses the feasibility of SGM-101, a fluorochrome-labeled anti-carcinoembryonic antigen monoclonal antibody, for intraoperative near-infrared fluorescence imaging of colorectal brain metastases by injecting SGM-101 intravenously 3 - 5 days prior to surgery.
The purpose of this multi-phase research study is to understand how consultation of cancer care with a geriatrician can best improve outcomes for older adults with gastrointestinal malignancies.
This is a multi-cohort proof of concept study involving patients with metastatic gastrointestinal cancers. In the first cohort of treatment-naïve patients, the investigators intend to create cancer organoids for 100 subjects. Then, the investigators intend to evaluate ex-vivo prediction of treatment outcomes using QPOP (see section 4.0 for detailed sample size calculation). Patients enrolled on study will undergo a fresh biopsy of tumour lesion to obtain cells that will be used to generate patient-derived tumour organoids. These patients will go on to receive standard of care first-line chemotherapy +/- targeted therapy. Organoids will then be subjected to up to a 14-drug panel screening. The drugs in the respective drug panel have been shown to have activity in the respective cancers and would be used in the standard-of-care setting by treating physicians.
Doctors leading this study hope to find out if giving study participants' genetic information to cancer care providers will help personalize chemotherapy dosing decisions and decrease common chemotherapy side effects. Doctors leading the study will collect genetic information from study participants using pharmacogenomics/genotyping. Pharmacogenomics is the study of how the differences in our genes can affect our unique response to medications. This is a randomized study, which means that participants in this study will be randomly assigned (as if "by flip of a coin") to one of two different groups: a "pharmacogenomics group" or "control group".
A clinical trial to assess the safety and efficacy of genetically-engineered, neoantigen-specific Tumor Infiltrating Lymphocytes (TIL) in which the intracellular immune checkpoint CISH has been inhibited using CRISPR gene editing for the treatment of Gastro-Intestinal (GI) Cancer.
Earlier detection of disease recurrence will enable greater treatment options and has strong potential to improve patient outcomes. This project is translational and has the potential to lead to future translational research opportunities, including interventional trials in which therapeutic escalation is offered at the early circulating tumor DNA (ctDNA) molecular residual disease (MRD) detection timepoint. Ultimately, the integration of ctDNA into the clinical workflow has the potential to enhance cancer diagnosis, treatment, surveillance, and prognosis, and guide clinical decision-making in this era of personalized precision medicine.
