Filter by:This phase I/II trial studies the side effects of pulmonary suffusion in controlling minimal residual disease in patients with sarcoma or colorectal carcinoma that has spread to the lungs. Pulmonary suffusion is a minimally invasive delivery of chemotherapeutic agents like cisplatin to lung tissues. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Pulmonary suffusion may also be useful in avoiding later use of drugs by vein that demonstrate no effect on tumors when delivered locally.
Data of 100 colorectal cancer patients with liver metastases who received stereotactic radiotherapy of Cyberknife or microwave ablation in the multicenter of the research group from June 2019 to May 2021 were collected, as well as follow-up data.To evaluate the clinical efficacy of stereotactic radiotherapy and microwave ablation in liver metastases.In addition, the local control rate and side effects of stereotactic radiotherapy and microwave ablation in the treatment of liver metastases were explored, and the efficacy and safety of different doses of stereotactic radiotherapy were determined.
adherence of digital follow-up in a population of elderly patients.
This pilot clinical trial studies how well ultrasound works in detecting oxaliplatin-induced neuropathy in patients with gastrointestinal cancer. Ultrasound may work better in diagnosing and detecting neuropathy in gastrointestinal cancer patients treated with the chemotherapy drug called a oxaliplatin.
This is a prospective cohort pilot study. The investigators are planning to develop an original, standardized colorectal anastomosis inspection method, which will systemically inspect the anastomosis vascularity using the indocyanine green fluorescent angiography intraluminally and intraperitoneally, the air leak test, the methylene blue test, the tension in the anastomosis inspection, patients' risk factors scale sum. The summarized evaluation will determine the final anastomotic leak risk.
Acetylsalicylic acid (ASA) seems the ideal colorectal cancer (CRC) chemoprevention agent. Several ongoing trials are testing the effect of ASA as co-therapy in CRC. The mechanisms of action, the appropriate dose and the ideal target population are unknown. The investigators have demonstrated that doses of 100 mg of ASA induce direct and partial but persistent acetylation of the cyclooxygenase (COX) isoenzyme COX-1 in the normal colorectal mucosa. The primary objective is to perform a study of aspirin by using a proteomic assay for comparing platelet COX-1 and CRC mucosal COX-1 after different doses of ASA. Secondary objectives are: the measurement of prostaglandin E2 (PGE2) and phosphorylated S6 protein (p-S6) levels in CRC mucosa, the assessment of indirect biomarker of aspirin action (serum thromboxane B2 (TXB2) and urinary levels of 11-dehydro-TXB2 (TX-M)), the evaluation of systemic biomarkers of inflammatory/tumorigenic COX-2 by assessing urinary levels of major metabolite of PGE2 (PGE-M). Methods: Phase II randomized clinical trial in 60 patients with newly diagnosed CRC in 3 groups of 20 patients receiving 100 or 300 mg/day, or 100 mg/12 hours of enteric-coated ASA for 3±1 weeks, prior to definitive treatment by surgery. Main outcome: Acetylation of COX-1 and COX-2. Eicosanoid levels in target organs. Expected results: Evidence for the current uncertainty about the mechanisms of action and the dose required to obtain the best chemopreventive effect with ASA in CRC. Confirm acetylation of COX as a key biomarker of efficacy with ASA.
This trial will study SGN-CD47M to find out whether it is an effective treatment for different types of solid tumors and what side effects (unwanted effects) may occur. The study will have two parts. Part A of the study will find out how much SGN-CD47M should be given for treatment and how often. Part B of the study will use the dose found in Part A and look at how safe and effective the treatment is.
The purpose of this study is to study the impact of Western lifestyle, including moderate alcohol consumption and delayed eating patterns on studying individuals' susceptibility to colorectal cancer. This study aims to increase our ability to identify individuals at risk for colorectal cancer in the future. Each subject will experience four conditions (each for one week in duration with a week +/- 2 days wash-out in between): (1) "right-time eating" / no alcohol, (2) "right-time eating" / with alcohol, (3) "delayed-eating" / no alcohol, (4) "delayed-eating" / with alcohol. The order of experiments will be randomized [concealed randomization]. All subjects will undergo unprepped sigmoidoscopy after each week of intervention. In Aim 2, all subjects will have an option to undergo a 24h circadian assessment in the Biological Rhythms Research Lab after each week of intervention. The Investigator will assess (i) central circadian rhythms by collecting hourly salivary samples for melatonin assays and (ii) peripheral rhythm in the intestinal tract by buccal swabs once every 2h (12 time points) as well as by rectal sampling twice (every 12 hr). For Aim 3, sigmoidoscopy without sedation will be used to obtain colonic samples as the safe method compared to colonoscopy, which has some small but finite risks associated with the procedure (e.g, bleeding or perforation) as well as sedation.
The aim of this study is to assess the performance of the CB-17-08 to help endoscopists find potential mucosal polyps during the colonoscopy procedure, without significant noise disturbing the endoscopist attention, nor negative interference with the lesions detection than with the standard colonoscopy alone: the study will investigate whether the use of the device provides an increase in the number of adenomas per colonoscopy as compared to standard colonoscopy. The study will also evaluate the safety of the CB-17-08, assessing if the use of the system increases the total number of excisions without a commensurate number of adenomas as compared to standard colonoscopy.
The purpose of this study is to evaluate the dose, safety, immunogenicity and early clinical activity of GRT-C903 and GRT-R904, a neoantigen-based therapeutic cancer vaccine, in combination with immune checkpoint blockade, in patients with advanced or metastatic non-small cell lung cancer, microsatellite stable colorectal cancer, pancreatic cancer, and shared neoantigen-positive tumors. Based on the Phase 1 data, an updated vaccine candidate (SLATE-KRAS or version 2) was developed that removed 16 of the 20 mutations included in the original vaccine (version 1) and solely targets KRAS mutations.
