Filter by:At present, radical resection ± preoperative neoadjuvant chemotherapy for colorectal cancer is still the standard comprehensive treatment. In recent years, immunotherapy of PD-1 monoclonal antibody has a significant effect in the second-line/first-line treatment of dMMR/MSI-H advanced colorectal cancer and the neoadjuvant treatment of early colorectal cancer. Synchronous multiple primary colorectal cancer (sMPCC) is a relatively rare type of colorectal cancer (CRC) that refers to the simultaneous occurrence of 2 or more independent primary malignancies in the colon or rectum. The recent large-scale, single-center retrospective study of the investigator showed that compared with single primary colorectal cancer (SPCRC)patients, the incidence of dMMR/MSI-H was significantly higher in sMPCC patients. Besides, a certain proportion of sMPCC patients could both have MSI and MSS tumors at the same time. There is no standard regimen for this patients so far. This study intends to treat the MSI-H/MSS (dMMR/pMMR) mixed sMPCC patients with combination of mFOLFOX6+PD-1 monoclonal antibody neoadjuvant therapy, and treat the all-MSI-H (dMMR) sMPCC patients with single-drug PD-1 monoclonal antibody neoadjuvant therapy. Given the current gaps in the guideline, the investigator intends to take the lead in carrying out this open, multi-center, prospective clinical phase II study. This study might provide a clinical evidence for individual treatment of sMPCC patients, in preserving the functions and organs to the greatest extent.
The main purpose of this clinical trial is to learn about the good and the bad effects of all trans retinoic acid (ATRA), atezolizumab and bevacizumab as a possible treatment for advanced colorectal patients. Participants will be treated with the following combination of these drugs: 1. ATRA will be given in a pill form to be taken twice a day at home for 7 days starting on day 1 of a cycle. 2. Atezolizumab will be given through a vein in arm or through mediport over 60-90 minutes every 2 weeks in the outpatient chemotherapy infusion centers at UTSW. 3. Bevacizumab will be given through a vein in arm or through mediport over 20-40 minutes every 2 weeks in the outpatient chemotherapy infusion centers at UTSW.
This trial is a first in human (FIH) clinical trial in patients with Colorectal cancer (CRC) after failure of at least three lines of previous therapy aiming to evaluate safety and efficacy of CC-3, a bispecific antibody (bsAb) with CD276xCD3 specificity developed within DKTK. CC-3 binds to CD276 on cancer cells as well as to tumor vessels of CRC, thereby allowing for a dual mode of anti-cancer action. CC-3 was developed in a novel format which not only prolongs serum half-life, but most importantly reduces off-target T cell activation with expected fewer side effects. A similar construct in this format with PSMAxCD3 specificity is presently undergoing clinical evaluation in patients with prostate cancer (NCT04104607), with very favorable safety and preliminary efficacy. The optimized format that CC-3 shares with its PSMAxCD3 "sister molecule" allows for application of effective bsAb doses with expected high anticancer activity. The clinical trial comprises two phases: The first phase is a dose-escalation part to evaluate the maximally tolerated dose (MTD) of CC-3. This is followed by a dose-expansion part to defined the recommended phase II dose. A translational research program comprising, among others, analysis of CC-3 half-life and the induced immune response will serve to better define the mode of action of CC-3.
The present study was to investigate if the incidence, patterns and surgical outcomes of mechanical ileus have changed in the era of minimally invasive surgery (MIS).
Colorectal cancer is a leading cause of cancer death. Detection and removal of polyps can reduce risk for developing colorectal cancer. After finding and removing precancerous polyps, repeat colonoscopy is routinely recommended. However, it is unclear whether repeat additional colonoscopy further reduces risk for colorectal cancer. For older adults age 75 and older, the lack of this information is especially important, given that the risks of colonoscopy go up with age. This research will evaluate whether older adults with a prior history of precancerous polyps have higher colorectal cancer risks compared to older adults who had a prior normal colonoscopy, and whether, among those with prior precancerous polyps, repeating a colonoscopy after age 75 is associated with reduced cancer risk. The investigators will synthesize these data and gather perspectives from Veterans and clinical stakeholders to make recommendations on whether older adults with a prior history of polyps should continue or defer colonoscopy after age 75.
Health establishments encourage the development of specific care pathways for the elderly by supporting Geriatric Peri-Operative Units (GPOU). Indeed, this shared care model has shown a clear reduction in mortality and the number of re-hospitalizations in patients 6 months after their care. The multidisciplinary approach of global management of the patient in the perioperative period aims to reduce surgical stress as well as the rapid restoration of previous physical and psychic abilities. Colorectal surgery, the main treatment for stage I to III colon cancer, is a morbid surgery. Despite numerous efficacy data on improved rehabilitation after colorectal surgery, care programs are not specific to the geriatric population and geriatric assessment criteria to describe the functional status of patients are not commonly used. The study investigators wish to evaluate the impact of GPOU treatment following colorectal surgery, on the evolution of several clinical parameters such as: functional status, morbidity mortality, quality of life, and lifestyle. The study investigators hypothesize that management in the GPOU for colorectal cancer surgery in patients aged 70 and over will improve functional status at 3 months, in comparison with traditional management. The proposed intervention should also lead to an improvement in patient satisfaction with care, complications and re-hospitalizations, nutritional status, lifestyle and patient survival.
This proposed Phase I clinical trial of SON-DP is an FIH, open-label, Phase Ia/Ib dose escalation and expansion study to evaluate the safety, tolerability, PK, and PD of SON-DP in participants with relapsed/refractory/intolerant to standard of care therapies, for advanced/ metastatic solid tumors.
The study involves the planned use of a new microwave-based device during colonoscopy procedures in 50 patients to assess the performance and safety of its use for detection of colorectal polyps and lack of normal clinical practice modification. The device is a final design version, which has been previously tested in several preclinical studies (including phantom studies, an ex vivo study with human tissues, and an in vivo study with porcine model) and in a pilot study in humans (NCT05477836)
The study is an interventional Phase II clinical trial aiming to optimize immunotherapy strategies for microsatellite-stable colorectal cancer. We will include three types of metastatic colorectal cancer patients: those without liver metastasis, or carrying BRAF V600E mutation, or unable to tolerate chemotherapy as their initial or second-line treatment. The participants will receive a combination treatment of regorafenib and KN046 which is a PD-L1/CTLA-4 bispecific antibody. Treatment efficacy and safety profile would be evaluated in this study.
This is a Phase 2 prospective, randomized, controlled, double-arm study to assess personalized self-management training (PSMT) intervention efficacy and patient experiences compared to standardized self-management training (SSMT). A total of 120 colorectal cancer (CRC) patients will be enrolled and randomized 1:1 to complete a 6-week self-management training program (either PSMT or SSMT) to be carried out by licensed occupational therapists with doctoral training. This study aims to examine whether PSMT is more effective in increasing adherence to healthy behavior recommendations compared to SSMT in CRC patients.
