Filter by:To improve detection of premalignant lesions in the gastrointestinal tract (the rectum and the esophagus) there is a need for better endoscopic visualization and the ability for targeted biopsies. The University Medical Center Groningen (UMCG) developed a fluorescent tracer by labelling the VEGF-A-targeting humanized monoclonal antibody bevacizumab, currently used in anti-cancer therapy, with the fluorescent dye bevacizumab-800CW (IRDye800CW). In several phase I studies and phase II studies, either completed or currently running, in the UMCG, the use of VEGF-A-guided near-infrared (NIR) fluorescence molecular endoscopy (FME) in combination with high-definition white light endoscopy (HD-WLE) shows an improved detection rate of early premalignant lesions. In this study the safety and feasibility of a next generation imaging system will be tested. This system uses immune optical coherence tomography (immuno-OCT) and near infrared fluorescence (NIRF) with the targeted tracer (Bevacizumab-800CW) for improvement of the detection of dysplastic lesions in Barret's esophagus (BE) and colorectal polyp detection. The system provides more depth information and can eventually be used without the guidance of the regular endoscopy system.
This clinical trial tests how well phytocannabinoids (cannabidiol [CBD] and tetrahydrocannbinol [THC]) work in reducing chronic chemotherapy-induced peripheral neuropathy (CIPN) in breast and colon cancer survivors. Neuropathy is the most common neurological symptom reported by cancer patients due to treatment. A variety of pharmacologic treatments have been evaluated to alleviate CIPN symptoms; however, no definitive treatment has been found to successfully treat all the symptoms of CIPN. Therefore, investigators continue to seek other possible treatment options including cannabis. Phytocannabinoids may be a particularly useful intervention for cancer patients given the limited effective treatments for CIPN. In addition, cannabis-based medicines have become tremendously popular as both cancer patients and clinicians are seeking therapies with fewer potential risks of dependency and other side effects. This trial is being done to provide cancer patients and clinicians with reliable information to help guide their use of phytocannabinoids to manage the tremendous distress and pain experienced by many cancer patients, which impacts their long-term quality of life.
Tumor-related inflammation is one of the hallmarks of cancers in general. Innate immunity specifically is a common denominator which is involved in the pathogenesis of both thyroid carcinoma and colon carcinoma. To improve the patient's outcome and identify novel therapeutic targets, one needs a deeper understanding of the tumor-induced changes in the bone marrow myeloid progenitor cells. Furthermore, treatment of these cells by nanoparticles or other agents that induce a program of 'trained immunity' may be a novel way to re-educate myeloid cells and their bone marrow progenitors in thyroid carcinoma patients. Lastly, the investigators expect that this approach could be effective also in other cancers of which colon carcinoma is here proposed as an additional model. The investigators hypothesize that by exposing myeloid cells or their progenitors to various agents that induce trained immunity (e.g. high-density-lipoprotein-methylene diphosphonate nanoparticles, recombinant and synthetic cytokines), these immune cells will undergo functional reprogramming to induce a tumor-suppressive phenotype. In the future, this could be explored as a novel immunotherapy for tumors that are refractory to conventional treatment.
The aim of the study is to evaluate whether lymph nodes draining the region of the carcinoma are located only inside the lines of standard resection or in some percentages are located outside as well. The visualized nodes draining the region of the carcinoma will be correlated to location, fluorescent yes/no and nodal positive/negative. The draining lymph nodes will be visualized using the fluorescent dye indocyanine green.

This research trial studies how well biospecimen collection works in identifying genetic changes in patients with breast, prostate, colorectal, liver, or kidney cancer or multiple myeloma undergoing surgery. Studying samples collected during surgery may add to the understanding of cancer by looking for the genetic changes that cause early cancer onset in people of certain racial and ethnic groups.
This clinical quality improvement study reviews and develops a clinical operations workflow to identify cancer patients who meet criteria for genetic counseling and testing. This study may improve utilization of genetic counseling and testing amongst community-based oncology providers caring for cancer patients in a rural and underserved area.
This phase II trial investigates how well oral cryotherapy plus acupressure and acupuncture compared with oral cryotherapy alone work in decreasing chemotherapy-induced peripheral neuropathy in patients with gastrointestinal cancer who are receiving oxaliplatin-based chemotherapy. Acupressure is the application of pressure or localized massage to specific sites on the body to control symptoms such as pain or nausea. Acupuncture is the technique of inserting thin needles through the skin at specific points on the body to control pain and other symptoms. Cryotherapy uses cold temperature such as oral ice chips to prevent abnormally increased pain sensation. Giving oral cryotherapy with acupressure and acupuncture may work better in decreasing chemotherapy-induced peripheral neuropathy from oxaliplatin-based chemotherapy in patients with gastrointestinal cancer compared to oral cryotherapy alone.
This phase I trial studies a new imaging technique called FAPi PET/CT to determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulate in normal and cancer tissues in patients with non-prostate cancer. The research team also want to know whether what they see on PET/CT images represents the tumor tissue being excised from the patient's body. The research team is also interested to investigate another new imaging technique called PSMA PET/CT. Participants will be invited to undergo another PET/CT scan, with the PSMA tracer (68Ga-PSMA-11). This is not required but just an option for volunteer patients. Patients who have not received an 18F-FDG PET/CT within one month of enrollment will also undergo an FDG PET/CT scan. The PET/CT scanner combines the PET and the CT scanners into a single device. This device combines the anatomic (body structure) information provided by the CT scan with the metabolic information obtained from the PET scan. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of, in the case of this research, 68Ga-PSMA-11 and 68Ga-FAPi, and 18F-FDG (if applicable). Because some cancers take up 68Ga-PSMA-11 and/or 68Ga-FAPi it can be seen with PET. CT utilizes x-rays that traverse the body from the outside. CT images provide an exact outline of organs where it occurs in patient's body. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors. The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers. PSMA stands for Prostate Specific Membrane Antigen. This name is incorrect as PSMA is also found in many other cancers. The function of PSMA is not well understood but imaging studies have shown that PSMA can be detected with PET in many non-prostate cancers. Imaging FAP with PET/CT may in the future provide additional information about various cancers.
This phase II trial studies how well nivolumab works in preventing colon adenomas in participants with Lynch syndrome and a history of surgery to remove part of the colon. Monoclonal antibodies, such as nivolumab, may interfere with the ability of tumor cells to grow and spread.
This pilot clinical trial studies how well social media listening works in improving clinical trial recruitment in patients with cancer. Social media listening and recruitment on Twitter may enhance enrollment for cancer-related clinical trials.
