Filter by:This observational study aims to test proteomics, metabolomics and proteoglycans as predictors of postoperative complications after colorectal surgery and as biomarkers of colorectal cancer. The main questions to answer are: - can these biomarkers predict anastomotic leakages - can these biomarkers predict recurrence after colorectal cancer - can these biomarkers be used as diagnostic tests for colorectal cancer - can these biomarkers be identified in the tumor Participants will undergo elective colorectal resection or stoma closure.
The aim of this prospective, observational cohort study is to assess the impact of iron deficiency anaemia on the incidence of perioperative complications and the quality of recovery after surgery in patients undergoing colorectal cancer surgery. The main questions the study aims to answer are: - whether the presence of preoperative iron deficiency anaemia leads to a poorer quality of postoperative recovery in patients undergoing colorectal cancer surgery - whether different combinations of complete blood count parameters (red blood cell indices) could be suitable diagnostic tools for the detection of iron deficiency in the latent stage (without laboratory-confirmed anaemia) in colorectal cancer patients. Blood samples for laboratory analyses will be collected from each study patient admitted to the surgical ward one day prior to elective surgery and on the first postoperative day during the stay in the intensive care unit. The pre-operative laboratory analyses include a complete blood count and serum iron status parameters (iron concentration, ferritin concentration, TIBC, UIBC and TSAT). Laboratory parameters analysed on the first postoperative day include complete blood count, serum concentration of electrolytes (Na, K, Ca, Cl, Mg), serum concentration of urea and creatinine, parameters of haemostasis (aPTT, PT, INR), serum concentration of C-reactive protein and procalcitonin. Data about overall morbidity, intraoperative complications, quality of postoperative recovery, red blood cell transfusion rate, all-cause infection rate, antibiotic usage, as well as length of hospital stay will be collected. The researchers will compare the group of patients with iron deficiency anaemia, the group of patients with iron deficiency in the latent stage and the control group to determine whether patients with iron deficiency have a higher incidence of perioperative complications and impaired recovery after surgery. The researchers will investigate whether iron deficiency can be detected at an early stage, when anaemia is not yet present, by calculating various red blood cell indices.
The goal of this phase III, open-label, non-inferiority randomized controlled clinical trial is compare upfront dose-reduced chemotherapy with the standard dose chemotherapy in older patients ( ≥70 years) with metastasized colorectal cancer, with regard to progression-free survival (PFS). The choice between monotherapy (a fluoropyrimidine) and doublet chemotherapy (a fluoropyrimidine with oxaliplatin) will be made for each individual patient based on expected risk of chemotherapy toxicity (according to the G8 screening). Patients classified as low risk of toxicity will be randomized between doublet chemotherapy in either full-dose, or with an upfront dose-reduction of 25%. Patients classified as high risk will be randomized between monotherapy in either full-dose or upfront dose-reduction. Primary outcome is PFS. Secondary endpoints include grade ≥3 toxicity, QoL, physical functioning, overall survival, number of treatment cycles, dose reductions, hospital admissions, cumulative received dosage and cost-effectiveness.
The goal of this observational research registry is to learn about health, wellbeing, and needs of survivors of young adult cancer (diagnosed between the ages of 18 and 39). The main question[s] it aims to understand are: - What are the levels of depression, anxiety, social support, and financial distress - Determine effectiveness of YASU programming by measuring changes over time With this registry, the investigators also plan to identify survivors who may be eligible for participation in future research studies pertaining to young adult cancer. Participants will be asked to complete electronic surveys every 6 to 12 months during participation in the registry.
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.
