Filter by:This is a prospective, randomized study designed to compare genotype-guided dosing to usual care in patients with pancreas cancer and colorectal cancer who are UGT1A1 intermediate metabolizers (*1/*28) (heterozygotes) and usual UGT metabolizers (*1/*1). All patients will be assessed for UGT1A1 genotype at screening and those with intermediate or usual UGT1A1 genotypes (*1/*28, *1/*1) will be randomized to genotype-guided dosing versus usual care.
The SoFiT study is a randomized controlled trial examining the effects of a behaviour change guided lifestyle intervention on increasing adherence to the World Cancer Research Fund cancer prevention guidelines, compared to the wait-list usual care group, on diminishing cancer-related fatigue in colorectal cancer survivors.
Although dietary vitamin D supplementation has been used in the clinical setting for decades, the effect of supplementary vitamin D consumption on the structure of the microbiome has not been studied in humans in fine scale or with concomitant adjustment for dietary intake. Understanding the interaction of vitamin D with the microbiome in humans could lead to important advancements in the understanding of how vitamin D together with diet impacts the microbiome composition, and ultimately, risk of EOCRC. This study has the potential to lay the ground work for an adjunctive therapy to manipulate the microbiome to reduce risk of EOCRC. This proposed study is designed to evaluate the effect of vitamin D supplementation on the normal structure of the microbiome and data will not be used to diagnose, prevent, cure or treat disease.
Extensive preclinical evidence suggests that short-term fasting and fasting mimicking diets (FMDs) can protect healthy cells and render cancer cells more vulnerable to chemotherapy and other therapies. However, fasting is difficult for the old and frail subjects.Therefore, FMDs may be more suitable for postoperative dietary intervention in cancer patients. Colorectal tumors have high glucose consumption, which makes tumor cells very sensitive to changes in nutritional metabolism of the surrounding environment (such as diet restriction / fasting). Previous studies have shown that cyclic FMDs are safe and feasible for cancer patients receiving chemotherapy alone. However, the effects of the FMD in patients under radical surgery for colorectal cancer have not been evaluated so far. This study aims to evaluate the impact of FMDs on postoperative recovery and outcomes of patients with colorectal cancer.
The overarching goals of the "PCSNaP" Research Study is to support the Abramson Cancer Center (ACC) of the University of Pennsylvania in carrying out its mission to increase colorectal cancer (CRC) screening completion among high-risk individuals living in a persistent poverty county by designing, conducting, disseminating and evaluating an electronic health record-based automated identification program to target effective, culturally-sensitive CRC screening navigation to individuals who have not completed an ordered colonoscopy or fecal immunochemical test (FIT).
The primary purpose of this study is to characterize the safety and tolerability of tucatinib (MK-7119) in Chinese participants with human epidermal growth factor receptor 2 positive (HER2+) advanced breast cancer, gastric or gastroesophageal junction adenocarcinoma (GEC), and colorectal cancer.
The investigators hypothesize that gut microbiome composition and the four bacterial gene markers (M3) show dynamic changes after endoscopic resection of advanced neoplasia, some key bacteria are associated with restoration of gut microbiome after endoscopic resection.
This is a first-in-human, Phase 1 open-label, multicenter, dose escalation, safety, pharmacodynamic, and PK study of exoASO-STAT6 (CDK-004) in patients with advanced Hepatocellular Carcinoma (HCC) and patients with liver metastases from either primary gastric cancer or colorectal cancer (CRC).
The purpose of this study is to retrospectively analyze colorectal cancer screening data of 40-74 year old population in Shipai Town, Dongguan City. In this study, the data of SDC2 Gene Methylation Test and Fecal Immunochemistry Test (Q-FIT) were screened from about 11,000 subjects who participated in Colorectal Cancer Screening in Shipai Town People's Livelihood Project from May 2021 to May 2022. Data from 822 subjects with positive SDC2 Gene Methylation Test and/or positive Fecal Immunochemistry Test (Q-FIT) results and with colonoscopy and/or pathological results were selected for retrospective analysis. This retrospective study evaluated the screening performance of SDC2 Gene Methylation Test and/or Fecal Immunochemistry Test (Q-FIT) for colorectal cancer using colonoscopy and/or pathological results as the clinical standard method.
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.
