Filter by:Background: A new cancer therapy takes white blood cells from a person, grows them in a lab, genetically changes them, then gives them back to the person. Researchers think this may help attack tumors in people with certain cancers. It is called gene transfer using anti-KRAS G12D mTCR cells. Objective: To see if anti-KRAS G12D mTCR cells are safe and cause tumors to shrink. Eligibility: Adults ages 18-72 who have cancer with a molecule on the tumors that can be recognized by the study cells Design: Participants will be screened with medical history, physical exam, scans, photography, and heart, lung, and lab tests. An intravenous (IV) catheter will be placed in a large vein in the chest. Participants will have leukapheresis. Blood will be removed through a needle in an arm. A machine will divide the blood and collect white blood cells. The rest of the blood will be returned to the participant through a needle in the other arm. A few weeks later, participants will have a hospital stay. They will: - Get 2 chemotherapy medicines by IV over 5 days. - Get the changed cells through the catheter. Get up to 9 doses of a medicine to help the cells. They may get a shot to stimulate blood cells. - Recover in the hospital for up to 3 weeks. They will provide blood samples. Participants will take an antibiotic for at least 6 months. Participants will have several follow-up visits over 2 years. They will repeat most of the screening tests and may have leukapheresis. Participants blood will be collected for several years.
Studies have shown that tumors from the same patient may respond very differently to the same therapeutic agents. This study aims to investigate the genetic basis of tumors that respond abnormally well or poorly to therapeutic agents in an effort to understand the fundamental genetic basis of this response. The present protocol seeks to retrospectively perform Exome, next-generation (DNA) sequencing and/or other molecular techniques on tumor samples to identify the genetic basis of a patient's exceptional response to chemotherapy.
Intraoperative tumor localization and resection can be enhanced using intraoperative fluorescence imaging and radiodetection. Labetuzumab specifically recognizes CEA which is is expressed on > 95% of colorectal cancers.. Therefore Indium-111-DOTA-labetuzumab-IRDye800CW is a perfect dual-labeled antibody for dual-modality image-guided surgery in peritoneal carcinomatosis of colorectal cancer.
The present study investigates the efficacy of a new Endoultrasound guided fine needle biopsy (EUS-FNB) device (AquireTM Boston Scientific= AQUIRE®) for obtaining histological tissue cylinders in the diagnosis of solid pancreatic tumors, submucosal tumors of the upper gastrointestinal tract (esophagus, stomach, duodenum) and lymph node disease..
This is a randomized, controlled, parallel, multicenter trial to determine the difference in post-operative anastomotic leakages in colorectal surgery, where anastomosis perfusion is evaluated using indocyanine green fluorescence imaging as an addition to standard surgical practice compared to surgical practice alone.
This is a Phase 1 study currently evaluating PO administered ompenaclid in combination with FOLFIRI and bevacizumab in patients with advanced (i.e., locally advanced and unresectable, or metastatic) previously treated colorectal adenocarcinoma. The single agent ompenaclid dose escalation stage and the ompenaclid in combination with FOLFIRI and bevacizumab dose escalation stage of the study has been completed; the expansion stage of ompenaclid in combination with FOLFIRI and bevacizumab is ongoing. In April-24 a protocol amendment added a new dose escalation and expansion stage which will evaluate ompenaclid in combination with FOLFOX and bevacizumab in patients with metastatic CRC. It is anticipated that a total of 30 patients will be enrolled in this new dose escalation and expansion stage of the study.
This is a multi-center, open label, repeat dose, Phase 1 study consisting of a Dose Escalation Phase and a Dose Expansion Phase to evaluate safety, pharmacokinetics, and clinical activity.
This is a randomized control trial aiming to investigate the use of a prehabilitation regimen for patients undergoing major GI cancer surgery and its effects on measurements of HRQOL, LOS, and post-operative complications. Participants will be randomized to either the Prehabilitation arm or the Usual Care arm (control group). The Prehabilitation arm will be prescribed both physical and psychological prehabilitation prior to undergoing surgery for their GI cancer. The Usual Care arm will be counseled to continue their current level of activity and given the information on exercise as outlined in the Cancer Care Ontario guidelines. Participants in the Usual Care arm will also be given the same activity tracker as patients in the Prehabilitation arm in order to eliminate the activity tracker as an intervention itself. Clinical, patient-reported outcomes and health system outcomes will be evaluated. Outcomes will be measured at consent (baseline), immediately preoperatively, and postoperatively at 1, 3 and 6 months. The investigators will collect measures of recruitment, attrition and self-reported compliance via a log completed by the coordinator during weekly patient phone calls.
This study proposes to establish a CT radiomics-based prediction model for identifying metastasis of each station lymph nodes in gastric cancer.
Patients with gastrointestinal cancer often experience physical deconditioning; this could lead to an increased risk of complications, especially when they require major abdominal surgical procedures. It has been suggested that physical training in the preoperative period could improve their condition, reducing the risk of complications. Although this topic has been investigated, it has not been established yet the best short preoperative aerobic exercise program to enhance the aerobic capacity in patients with gastrointestinal cancer who are going to be to surgical primary management, and consequently, to help patients dealing with the physiological stress involved in a surgical intervention. Main objective: To determine the efficacy and safety of a 4 weeks preoperative exercise program in patients with gastrointestinal cancer scheduled for primary surgery. Materials and methods: This is a Phase II single arm clinical trial that will include patients between 45 and 70 years, with confirmed gastrointestinal cancer (gastric, hepatic, colon or rectal cancer), without electrocardiographic abnormalities, and scheduled for primary surgery in 4 weeks or more since recruitment All the enrolled patients will receive a basal aerobic capacity assessment with the 6-minute walk test. Then, two physical therapist will prescribe them a supervised and individualized aerobic training program in 3 sessions per week during 4 weeks. Each session will last 50 minutes and will increase the heart rate target weekly (from 50% to 70% of the maximum heart rate). The aerobic exercise will be carried on a treadmill or in a stationary bicycle. The post intervention aerobic capacity will be measured at week 3 and 4 with the 6-minute walk test. The main efficacy outcome will be peak oxygen consumption (VO2 peak) and the safety outcomes will be exercise-related adverse events and the program adherence. This protocol was approved by the Instituto Nacional de Cancerología's Ethical Board
