Filter by:Large (≥20mm) colorectal polyps often harbor areas of advanced neoplasia, making them immediate colorectal cancer (CRC) precursors. Such polyps have to be completely removed to prevent CRC and to avoid surgery and/or adjuvant therapy. The laterally spreading lesions (LSLs) are removed via endoscopic mucosal resection (EMR). However, recurrence is common. Recent studies have found that the use of hybrid argon plasma coagulation (h-APC) for the ablation of the margin and base of resection post-EMR could significantly reduce the recurrence rate, and complete closure of the post-EMR defect can prevent other adverse pre- and post-procedure outcomes such as bleeding. We hypothesize that performing hybrid argon plasma coagulation (h-APC) margin and base ablation post-EMR for large (≥20mm) colorectal LSLs will demonstrate a lower recurrence rate compared to Snare Tip Soft Coagulation (STSC) margin ablation. We also hypothesize that performing complete closure of the EMR defect will result in lower rates of adverse events compared to cases where no defect closure is performed.
This is a single-arm, interventional, pilot clinical trial. Fifteen evaluable patients will have tumor-informed ctDNA testing at baseline and start botensilimab and balstilimab treatment. They will receive botensilimab and balstilimab in 6-week cycles until progression, after which mFOLFOX6 and bevacizumab or panitumumab will be added to the regimen. Subjects will have safety testing at baseline and every two weeks while on study drug. Study treatment with botensilimab and balstilimab, mFOLFOX6, and bevacizumab or panitumumab will be continued until radiographic or clinical progression, toxicity, or patient withdrawal. Subjects will have one safety follow up visit 30 days after the last treatment and will be followed for survival every 12 weeks for up to 2 years.
This is an open-label, phase II study that may provide evidence that taking S-adenosylmethionine (SAMe) supplementation prevents oxaliplatin, a type of chemotherapy drug, associated liver toxicity in patients with resectable colorectal liver metastases. Resectable means that it is able to removed with surgery. Patients will take two SAMe tablets in the morning and one tablet in the evening for 3-6 months (about 6-8 cycles of chemotherapy) in addition to oxaliplatin based chemotherapy followed by surgical removal of the colorectal liver metastases.
The primary objective is to determine the diagnostic sensitivity and specificity of the newly developed liquid biopsy based multiomics Colorectal Cancer (CRC) screening test (CRC-Appareo) for detecting advanced neoplasia (including colorectal cancer and advanced adenomas) in high risk patients and patients with confirmed CRC, using colonoscopy as the reference method. The secondary objective is to compare the screening performance of the multiomics Colorectal Cancer (CRC) screening test with commercially available FIT (Fecal Immunochemical Test) assay in detecting advanced neoplasia.
The overall aim of this study is to determine whether the Immunoscore associated with histopathological features of endoscopically resected stage T1 colorectal tumors is predictive of locoregional lymph node invasion, in order to better select patients eligible for an organ preservation strategy.
Colorectal cancer (CRC) in the United States (US) is the fourth leading cause of cancer- related deaths. In Puerto Rico (PR), the incidence and mortality rate of CRC is higher (41% and 14%) in comparison to the mainland US (38% and 13%). To reduce mortality, receiving a colonoscopy is considered the gold standard for early detection. Yet Puerto Ricans are less likely to adhere to this recommendation than individuals in the mainland US (52% vs. 65%). Fear of acute pain may contribute to this reluctance despite the administration of sedation and analgesia during the procedure. The American Society for Gastrointestinal Endoscopy's recommended current standard of practice is to administer opioids and benzodiazepines to achieve minimal and/or moderate sedation during a colonoscopy procedure. Because patients still have conscious awareness, adding an effective pain distraction tool, such a virtual reality (VR), to their pharmacological standard of care during this short procedure could improve outcomes through decreased opioid and anxiolytic administration. Strong evidence supports VR's effectiveness to distract patients from acute pain during brief medical procedures. To address this translational gap from research to clinical practice within a Hispanic oncology population receiving colonoscopies, an implementation science (IS) framework will be utilized to measure: reach, effectiveness, adoption, implementation, and maintenance. RE-AIM is an IS framework that systematically measures and supports sustainable adoption and implementation of evidence-based interventions into clinical practice. The purpose of this IS study will be to evaluate the translation of VR into clinical practice for patients during a CRC screening colonoscopy.
As a result of the little benefit obtained from standard treatments and the poor prognosis of these patients, the BRAF-V600E mutant MSS aCRC represents an unmet medical need requiring clinical research. The combination of encorafenib, cetuximab and binimetinib as second- or third-line treatment for mCRC resulted in significantly better outcomes than standard therapy in a phase 3 clinical trial, which also revealed treatment safety and tolerability to be acceptable. Compared to the control group (cetuximab and irinotecan or cetuximab and FOLFIRI), the triplet therapy cohort showed higher median overall survival (9.3 vs. 5.9 months) and response rates (26.8% vs. 1.8%). Grade 3 adverse events occurred in 65.8% and 64.2% of patients for triple-therapy and control groups, respectively. Based on these results, the investigators speculated that the combination of encorafenib, cetuximab and binimetinib could be used as induction therapy to improve treatment outcomes in BRAF-V600E-mutated MSS aCRC locally advanced initially unresectable but potentially resectable; initially resectable or initially unresectable but potentially resectable oligometastatic disease; and in patients with stage II-IV who have relapsed after chemotherapy (neo and/or adjuvant) or surgery, if the shorter time after resection or from treatment end to relapse is longer than 6 months.
The purpose of this study is to evaluate the safety and clinical activity of cemiplimab and the combination of cemiplimab/fianlimab in microsatellite unstable localized or locally advanced colorectal cancer diagnosed in patients age 70 or greater.
This research study is a randomized controlled trial that will observe changes in microbiome activity, changes in chemotherapy toxicity, and any changes in treatment outcomes between two groups of participants undergoing chemotherapy with either early-stage or metastatic colorectal cancer. The names of the study groups involved in this study are: - Exercise - Waitlist Control
Colorectal cancer is prevented by colonoscopy and polypectomy. Failure to recognize the endoscopic resection scar after Endoscopic Mucosal Resection (EMR) risks unrecognized recurrent or residual adenoma (RRA), which may propagate into post-colonoscopy colorectal cancer. Expert series suggest scar recognition and interrogation is well performed with a high negative predictive value of endoscopic imaging vs histopathology. In this study the authors will investigate the performance of endoscopic imaging in detecting RRA at an endoscopic resection scar amongst general endoscopist and the impact of a learning intervention on recognition of RRA.
