Filter by:Colorectal cancer (CRC) is one of the most common malignant tumours of human beings. Mismatch Repair-deficient (dMMR)/ Microsatellite Instability-high (MSI-H) CRC is a specific subtype of CRC, which accounts for approximately 15% of all CRC patients, and can not benefit from 5-fluorouracil (5-FU) adjuvant chemotherapy. Once patients have distant metastases, they are not sensitive to traditional palliative chemotherapy, and thus lead to much worse prognosis than that of mismatch repair-proficient (pMMR)/ microsatellite stability (MSS). A phase II clinical study of anti-PD-1 immunotherapy based on mismatch repair (MMR) status published in "N Engl J Med" showed that the objective response rate (ORR) of advanced colorectal cancer patients with dMMR received anti-PD-1 is 40%, and a longer response time can be obtained compared to conventional chemotherapy. Another study (ClinicalTrials.gov, NCT03926338) which investigating the effect of neoadjuvant PD-1 blockade with toripalimab, with or without celecoxib, on mismatch repair-deficient or microsatellite instability-high, locally advanced, colorectal cancer. The result revealed that all 34 patients had an R0 resection. 15 of 17 patients (88%) in the toripalimab plus celecoxib group and 11 of 17 patients (65%) in the toripalimab monotherapy group had a pathological complete response. In theory, anti-PD-L1 drugs should have fewer immune side-effects than anti-PD-1 drugs. However, there are no reports of anti-PD-L1 neoadjuvant therapy for the dMMR/MSI-H colorectal cancer. Therefore, the aim of this study was to investigate the efficacy and safety of anti-PD-L1 monoclonal antibody (Envafolimab) as neoadjuvant immuntherapy for resectable local advanced colorectal cancer patient with the dMMR/MSI-H.
Fruquintinib DDI Study with P-gp and BCRP Substrates
This is an observational study with the goal to improve the robustness of the scientific evidence linking Fusobacterium nucleatum (Fn) and/or other microorganisms to colorectal cancer (CRC) onset and/or progression. This is an approximately three-year study. There are two phases to this study, including: 1) pilot phase, 2) full study. There are also five arms in this study including cancer-free, pre-cancerous, and Colorectal cancer stages (I-III). The pilot study will include the recruitment of 50 participants per group (i.e., total of 250 participants). The full study will have an additional 150 participants per group (total of 1,000 participants). This study will recruit using clinical sites in the United States. There are 5 timepoints in this study. If the participants are found to be medically eligible through diagnosis and medical information, they will provide samples (including: saliva, blood, urine, stool and tumor biopsy) at each timepoint and during the study. They will also answer health and wellness questions during this study. Additional data collection, including medical data, biopsies and other biological samples might happen at interim timepoints in case of adenoma/cancer disease progression (recurrence, metastasis). The participant's healthcare provider will determine if additional biopsies are required as a part of the standard of care. If collected, additional samples will be sent for research purposes.
The purpose of this clinical research is to establish a multi-omics model based on genomics，transcriptomics，gut microbiota in predicting pathologic response after neoadjuvant chemoradiotherapy combined PD-1 antibody given to patients with locally advanced rectal cancer.
With increasing age and the additional impact from the bowel cancer and the chemotherapy and/ or radiotherapy it has been described that testosterone (a male hormone produced naturally in the body) levels are reduced. Testosterone has an impact on numerous body functions including the muscle mass and quality. Previous studies have identified that muscle mass is reduced as a result of ageing but also because of the deleterious effect of cancer and chemotherapy and/or radiotherapy. There is growing evidence from published studies that patients with better muscle mass and quality, do better after surgery. Mr Jenkins and his team are therefore looking at ways, the investigators can try and prevent or reduce this muscle loss and therefore improve patient outcomes. The aim of this study is to assess whether using testosterone replacement therapy in the form of a topically applied gel daily for a total of 12 weeks, is feasible and acceptable by the patients who are diagnosed with colorectal cancer and are waiting to undergo surgery. The investigators will also collect information related to the testosterone replacement therapy such as questionnaires on the quality of life, fatigue and muscle mass, and blood biomarker changes in the blood.
The increase in the survival of cancer patients and the incidence of cancers leads to a rapid increase in the number of people living after a diagnosis of cancer. Occupation during chemotherapy treatment time has been identified as an excellent way to support cancer patients. Studies show that distraction interventions increase tolerance to treatment, by decreasing the importance given to negative stimuli associated with chemotherapy and increasing pleasurable emotions. In this context, virtual reality (VR) is a promising intervention for patients receiving chemotherapy. VR is considered a powerful painkiller, even more effective than other distractors, such as movies or video games for example. Several studies have shown short-term beneficial effects of integrating VR in patients undergoing chemotherapy. This intervention would help patients better adhere to and tolerate treatment. Considering that positive emotions could be one of the underlying processes necessary for the effectiveness of VR, it would be possible to support the cancer patient towards better overall well-being thanks to these new technologies. Investigators can therefore ask themselves the question of the impact that VR used during chemotherapy can have on the adaptation of patients to the disease and its treatments as well as on their psychological distress in the medium and long term.
This study is a single-arm, prospective, open-label observational clinical study to evaluate the efficacy and safety of Bevacizumab combined with Oxaliplatin and TAS-102 in patients with advanced unresectable rectal cancer.

This multi-center study will compare multi-target DNA and quantitative FIT stool-based testing to colonoscopy in individuals with Cystic Fibrosis (CF) undergoing colon cancer screening with colonoscopy. The primary endpoint is detection of any adenomas, including advanced adenomas and colorectal cancer (CRC).
Surgery with integrated treatment for metastatic colorectal cancer (mCRC) has created a new clinical setting known as mCRC with no evidence of disease (NED). However, these patients have a high risk of developing persistent cancer. This study aimed to investigate the efficacy and safety of Tislelizumab combined with capecitabine as a maintenance treatment for patients with mCRC-NED.
