Filter by:CROSCO-1 study is a national, multi-center, prospective observational study presenting patients to the emergency departments of the participating centers with obstructive left colon cancer (in the absence of metastases and peritoneal carcinomatosis) undergoing primary surgical tumor resection with a primary colorectal anastomosis (associated or not with a diverting loop ileostomy) or without a primary anastomosis ("Hartmann's procedure") or staged resection after endoscopic stenting with Self-expandable Metallic Stent (SEMS). The main questions it aims to answer are: - the Stoma rate at 1 year after tumor resection - the 30-day and 90-day major morbidity and mortality - 1-year quality of life (EQ-5D-5L test) - Timing of chemotherapy initiation and type of chemotherapy regimen. Participants will have an obstructive left colon cancer localized (no peritoneal carcinosis or distant metastasis). Researchers will compare: primary surgical tumor resection with a primary colorectal anastomosis (associated or not with a diverting loop ileostomy) or an "Hartmann's procedure" with a staged resection after endoscopic stenting with SEMS.
Cancer is a frequent disease considering that one person out of three will be confronted with it in their lifetime. Cancer patients often express complaints related to cognitive impairment as an outcome of their oncological treatment. These cognitive disorders have a significant impact on the patient's and their carer's quality of life. Therefore, it appears necessary to have a reliable, quick and simple tool in order to detect cognitive impairment. The rationale of this study relies on 3 main points : - The cognitive complaint frequently reported by cancer patients - The difficulty in reliably demonstrating the cause of this complaint through conventional neuropsychological tests - The interest of cognitive processing speed as an indicator of cognitive dysfunction The primary objective of the study is to evaluate a potential variation of cognitive processing speed at the Saint-Louis Lille Battery (SSLIB) between the beginning and during (4 months after the beginning) the oncological treatment of adults with breast cancer or colon cancer.
Participation in medical trials usually favors a particular demographic group. But there is limited research available to explain what trial attributes affect the completion of these specific demographic groups. This trial will admit a wide range of data on the clinical trial experience of Colon Cancer patients to determine which factors prevail in limiting a patient's ability to join or finish a trial. It will also try to analyze data from the perspective of different demographic groups to check for recurring trends which might yield insights for the sake of future Colon Cancer patients.
Background: Laparoscopic assisted right hemicolectomy is recommended for right colon cancer. As a more minimally invasive procedure, intracorporeal ileocolic anastomosis has potential advantages: reducing torsion and traction on the mesentery, reducing skin incision length and enhancing postoperative recovery. However, the longer operative time, greater risk of intra-abdominal infection and steep learning curve for intestinal anastomosis performed under laparoscopic conditions, does this increase the incidence of postoperative complications, especially the incidence of anastomotic leakage, and whether it affects There is no high-level research evidence on the survival of patients. Study design: COlOR IV study is an international prospective, multicenter, randomized controlled clinical study of intraperitoneal anastomosis versus extraperitoneal anastomosis after laparoscopic right hemicolectomy for colon cancer . The study will include a quality assessment phase before randomisation to ensure required competency level and uniformity of the intracorporeal and extracoporeal techniques. Endpoint: Primary outcome is anastomotic leakage within 30 days after surgery. Main secondary endpoint is 3-year disease-free survival rate. Secondary endpoints are mortality and morbidity, postoperative recovery, overall survival, surgical specimen quality, quality of life. Statistics: The primary endpoint is anastomotic leakage within 30 days after surgery. The anastomotic leakage rate was set to 2% in the both groups, and an increase in the incidence of anastomotic leakage of 2.5% was considered inferior. The one-sided significance level was 0.025, the power was 0.9. The dropout rate was 20%, and taking into account the post-randomization analysis (dropout 5%), the total sample size was 1158. There were 579 cases in the intracorporeal anastomosis group and 579 cases in the extracorporeal anastomosis group. Main selection: Patients with histologically proven right colon cancer (cecum, ascending colon and proximal 1/3 of the transverse colon malignant tumor), clinically stage I-III, and intention for right hemicolectomy with primary anastomosis. Hypothesis: The hypothesis is that intracoporeal anastomosis will have comparable anastomotic leak rate and 3-year DFS, but faster postoperative recovery with extracoporeal anastomosis.
The objective is to investigate the efficacy and safety of Envafolimab combined with XELOX in neoadjuvant therapy for locally advanced colon cancer
Anesthesia management in colon cancer surgery affects the postoperative mobilization, discharge and oral intake times of the patients. Due to the side effects of opioids, their use is tried to be reduced and therefore regional anesthesia methods are preferred in suitable patients. Especially in the preoperative period, opioid use has a negative effect on the recovery processes, morbidity and mortality of the patients. Epidural analgesia, a central block method, is recommended for postoperative pain control in ERAS protocols. Opioids suppress cellular and humoral immunity. Epidural analgesia reduces both opioid consumption and surgical stress response. It has been shown that epidural analgesia maintains the immune functions of patients and is associated with a decrease in tumor recurrence. It has also been shown to reduce postoperative pain, hypercoagulability and pulmonary complications, increase exercise capacity and accelerate the return of intestinal functions to normal. In line with this information, in this study, it was aimed to investigate the differences in the postoperative period in patients managed with regional anesthesia. In the study, it was planned to create two groups who underwent open surgery for colon cancer. The first group will be operated under general anesthesia and the second group will be operated under combined spinal-epidural anesthesia with ketofol sedation. An epidural catheter will be inserted in both groups for postoperative pain management. In the study, patients' age, gender, weight, comorbidity, ASA score, amount of local anesthetic used, postoperative VAS scores, mobilization time, time to start oral intake, nasogastric withdrawal time, drain removal time, urinary catheter withdrawal time, hospitalization time and total cost will be evaluated.
Quantitative faecal immunochemical testing (qFIT) is used to test for blood within faeces that cannot always be visible. The presence of blood in the stool has been shown to be a finding where there may be a problem within the large bowel. The test is able to give a numeric value to the blood in the stool and based on this result, further investigations can be planned, or if normal reassurance given. The test is not perfect and minor bowel problems such as haemorrhoids (piles) can give a raised result. However, we have also seen raised results in people who when investigated have a completely normal large bowel. A small degree of 'physiological' non-visible bleeding is likely a normal part of life and for the majority this does not lead to a raised qFIT result. It may be the case in people who have a raised qFIT but then go on to have a completely normal colonoscopy (telescope investigation of the large bowel) that there is a genetic predisposition that increases the amount of normal 'physiological blood' that they produce. This leads to the test being falsely positive and the person undergoing an unnecessary investigation. This study aims to use saliva to test for known genetic markers that effect blood clotting and can increase how much someone bleeds. By comparing the occurrence of these genetic markers in people with a raised qFIT and normal colonoscopy to those with a normal qFIT and normal colonoscopy, we can test this theory. Should this be the case it will help explain why the test can be raised in normal large bowel and could lead to different levels of positivity being used for different people.
FOLFOX, the first-line regimen based on 5-FU and oxaliplatin, is adjuvant chemotherapy for pathologic stage II/III colorectal cancer patients. Among various side effects of FOLFOX, chemotherapy-induced anemia occurs in about 30% of patients with FOLFOX chemotherapy. An oral iron supplement is a widely accepted treatment for chemotherapy-induced anemia, but an oral iron supplement has a lot of inconveniences that can make patients' adherence worse, such as gastrointestinal discomfort, a long period of oral intake, and late recovery of serum iron level. Intravenous iron infusion has been recently reported to be effective and safe to correct anemia. Previous studies reported that intravenous iron is also effective to correct chemotherapy-induced anemia. However, there is a paucity of studies associated with colorectal cancer patients with FOLFOX chemotherapy. This study aimed to evaluate the effect of intravenous iron on chemotherapy-induced anemia after FOLFOX chemotherapy for patients with colorectal cancer compared with the effect of oral iron supplements. Parameters including serum Hb, serum iron, serum ferritin concentrations, total iron-binding capacity, absolute neutrophil count, platelet, albumin, C reactive protein, hepcidin, soluble transferrin receptor, and IL6 will be analyzed. In addition, information on chemotoxicity, adverse events during chemotherapy and quality of life will be collected and analyzed.
10%-15% of early-stage colon cancers harbour either deficient mismatch repair (dMMR), microsatellite instability high (MSI-H) is characterised by high tumour mutational burden and increased lymphocytic infiltrate. Metastatic dMMR colon cancers are highly sensitive to immune checkpoint inhibition.The MSI phenotype is associated with a better prognosis than MSS in stage II and III CRCs. However, there are conflicting data about the benefit of adjuvant chemotherapy in this group of patients. We are conducting a single arm study phase II trial to determine if the anti-PD-1 antibody Tislelizumab improves disease-free survival (DFS) in patients with high risk stage II and stage III dMMR/MSI-H colon cancer.
Our aim of this study is to compare the difference in lymph node yield in CME specimens versus those patients having a standard right hemicolectomy for right sided cancer .The secondary aim of this study was to investigate whether there is an interaction between greater lymph node harvest towards increased survival. Another subgroup analysis of this study is to compare the complications and oncological outcome between laparoscopic versus Robotic CME.
