Filter by:Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide. Microsatellite instability or mismatch repair deficiency occurs in 20% of CRC, and is predominantly found in non-metastatic tumors. The success of the CheckMate 142 and KEYNOTE-177 clinical trials has shifted the treatment paradigm of the MSI/dMMR CRC, which has led to the adoption of immune checkpoint inhibitors (ICI) by international treatment standards. However, despite the encouraging effects of ICI, up to 30% of patients are resistant to treatment and exhibit rapid disease progression shortly after starting ICI. On the other hand, around 30% of patients treated with ICI demonstrate prolonged responses to the treatment with a duration of response of over 40 months. Furthermore, for ~10% of patients, treatment with ICI results in pseudo-progression - a phenomenon of a short-term increase followed by the decrease of the tumor volume. Currently, the mechanisms and biomarkers associated with the response or resistance to ICI in MSI-positive CRC are largely unknown. Select studies suggest that BRAF mutations (specifically, BRAF p.V600E) might negatively affect the patients' progression-free survival following ICI, however, these data are premature. The primary hypothesis is that the clonal heterogeneity and the evolution of MSI status of MSI-positive CRC will play a role in the development of ICI treatment resistance. The primary objective of the study is to investigate the dynamics of MSI status in serial liquid biopsy samples from patients with MSI-positive tumors receiving ICI.
This trial evaluates how inhalational anesthesia (drawn in through the lungs) and total intravenous anesthesia (TIVA) (through a needle in a vein in the arm) change the body's ability to recover from surgery or whether they impact the immune system immediately after surgery in patients with colon cancer. It is unknown whether these types of anesthesia change recovery from surgery or change the chances cancer comes back following surgery. This study may help researchers learn how different types of anesthesia affect recovery from colon cancer surgery.
This clinical trial evaluates whether an adaptive text-message intervention is useful in helping survivors of colorectal cancers (CRC) eat more whole grain foods and less refined grain foods. Most CRC survivors don't achieve the recommended intakes of whole grains or fiber, even though there is strong evidence that a high-fiber diet rich in whole grains lowers the risk of death from CRC. Dietary interventions are a promising approach for reducing death from CRC, and text message interventions specifically are a promising tool for reaching diverse populations. This trial evaluates a text-message based dietary intervention that continuously adapts message content to be specifically tailored for the participant for increasing whole grain consumption.
This phase II/III trial compares treatment with encorafenib and cetuximab to usual care (patient observation) for reducing the chance of cancer recurrence after standard surgery and chemotherapy in patients with BRAF-mutated stage IIB-III colon cancer. Encorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of tumor cells. This may help keep tumor cells from growing. Giving encorafenib and cetuximab after standard surgery and chemotherapy may be more effective at reducing the chance of cancer recurrence compared to the usual patient observation.
This study is a non-randomized, open-label, multi-cohort, multi-site, pilot feasibility therapeutic trial. The study will enroll 20 patients across 4 cohorts (CRC, gastric, PDAC, and HCC/intra-hepatic-/extra-hepatic-, gall bladder adenocarcinomas) diagnosed with histologically confirmed GI cancers. These patients will have already completed all Standard of Care (SOC) treatments (including neoadjuvant, surgery, local therapies, and/or adjuvant therapy as applicable), as defined by the treating primary physician or research team, with curative intent but have a positive SignateraTM tumor-informed ctDNA test and NED radiographically by standard imaging within 28 days prior to enrollment and within 1 year of completing all curative-intent therapy. All patients will be treated with intravenous (IV) atezolizumab 1200 mg IV and bevacizumab 15 mg/kg on Day 1 of 21-day cycles until disease recurrence, ctDNA POD, unacceptable toxicity, or subject withdrawal of consent with a maximum 12 month total duration of study therapy. Atezolizumab and bevacizumab drug will be provided.
The proposed study is a bidirectional analytical study, composed of a retrospective and a prospective cohorts. Patients with stage II - III colorectal cancer undergoing oncological surgery will be analyzed. The study will include a convenience sample of 100 individuals. Fifty cases will be included retrospectively and fifty prospectively. The study aims to evaluate the benefit of using the Immunoscore test as a predictor of recurrence in patients with operated stage II-III colon tumors. It will also be evaluated the impact on oncologic decision and costs.
This study is an interventional open label prospective study that aims to assess both overall and disease-free survival of patients treated with LDLT, partial or whole graft LT from deceased donors for unresectable CRLM. Secondary outcomes are graft survival and donor outcomes in terms of safety and quality of life. Donor selection is performed according to the currently used Institutional and National standards and protocols.
This is a phase 1b, prospective, single arm, non-randomized, open-label clinical trial determining the efficacy of adjuvant trifluridine and tipiracil (TAS-102) in combination with irinotecan in patients with ctDNA positive colon adenocarcinoma.
In this translational research study, Formalin-Fixed-Paraffin-Embedded (FFPE) tumor tissue blocks from patients with early-stage (II-III) colorectal cancer will be assessed for a comprehensive cancer gene panel from NIPD Genetics (https://www.nipd.com/) targeting regions in 37 clinically relevant cancer genes. The colorectal cancer panel includes an extended list of clinically relevant genes, designed to target clinically actionable and clinically significant mutations that will provide physicians with genetic information regarding a) prediction of the patient's response to targeted therapy, b) prognosis, that is, prediction of clinical outcome, c) diagnosis and molecular classification of colorectal cancer.
