Active clinical trials for "Colorectal Neoplasms"

We performed a retrospective data analysis of patients with synchronously metastasized colorectal cancer, comparing the histological response on the primary tumour to chemotherapy combined with either vascular endothelial growth factor (VEGF) or epidermal growth factor receptor (EGFR) inhibition.

Patients undergoing an operation for colorectal cancer are normally treated with non-steroid-anti-inflammatory-drugs (NSAIDs) e.g. ibuprofen as pain medication after the operation. It is well known that NSAIDs can be harmful to kidney-and heart patients and some studies also have shown an increased risc of surgical complications after treatment with NSAIDs. On the other hand recent studies have found a preventive effect of NSAIDs on colorectal cancer recurrence thus leaving the colorectal surgeon in doubt whether NSAIDs are beneficial or harmful to colorectal cancer patients. In the department of colorectal cancer surgery at Zealand University Hospital it was decided to leave out NSAIDs from the 1st of april 2016. This study will investigate if there is a change in consumption of opioids before and after omission of NSAIDs. This will be an important finding because opioids also have harmful side-effects as well as a risk of addiction. The investigators will also compare the blood samples and see if there is signs of impaired renal and cardiac function in the group that was treated with NSAIDs. Finally the long term outcomes will be investigated such as cancer recurrence and death in the two groups.

The feasibility and efficacy of emergency curative resection of complicated colorectal cancer is still controversial. This prospective study aim is to assess surgical and oncologic outcomes after emergency compared to elective curative resection of colorectal cancer

The presence of a BRAFV600E mutation is considered a marker of poor prognosis in patients with mCRC, and findings from clinical trials have largely remained inconclusive regarding the efficacy of first line treatments for BRAF-mutant mCRC patients. In the absence of targeted/specific treatment for BRAF-mutant mCRC, treatment practices can vary based on local practices and guidelines. There is, therefore, an unmet need to document the current practices for first-line treatment of BRAF-mutant mCRC, and their effectiveness and safety in a real-world setting. This real-world, multicenter non-interventional study (NIS) will describe the treatment patterns, effectiveness and safety of current treatment regimens in BRAFV600E mutant mCRC patients in Europe, with the aim to put the clinical study findings of the ongoing Phase 2, single-arm, open label trial (ANCHOR) into context of the current treatment landscape excluding investigational therapies. Additionally, the NIS output may be used to support future health technology assessment submissions and publications.

This study attempts to compare safety and long-term oncological outcomes between laparoscopic surgery and open surgery in the treatment of clinical T4b Colorectal cancer.

This study is a retrospective study to compare the efficacy and safety between trifluridine/tipiracil (TAS-102) plus bevacizumab (BEV) with TAS-102 monotherapy in refractory metastatic colorectal cancer (mCRC) from November 2020 to October 2022 at the Hunan Cancer Hospital.

The survival of the refractory CRC is dismal and therapy options are limited ，the researchers aim to investigate the efficacy, safety, and predictors of fruquintinib plus PD-1 in refractory MSS metastatic colorectal cancer in a real-world setting.

Colorectal cancer (CRC) is the second most commonly occurring cancer worldwide. Thirty-five percent of CRC patients are diagnosed at stage II/III, and their outcome differs even if they are in the same stage. Previous study found that the microenvironmental collagen is associated with tumor progression and metastasis. Whether tumor microenvironmental collagen signature is associated with colorectal cancer prognosis still remains unknown. We hypothesize that the tumor microenvironmental collagen signature of colorectal cancer is associated with prognosis.

Participants will be mailed an invitation to complete CRC screening along with a fecal immunochemical test (FIT) kit, containing a 1-sample "Polymedco Over the Counter (OC) Sensor FIT", simplified English/Spanish instructions on performing the test, educational information about colorectal cancer screening and a return mailer with prepaid postage. Processes that will be used to promote screening completion include automated and "live" phone call reminders to encourage completion of FIT testing. Participants will be randomly assigned to 1 of 5 interventions across 3 conditions, described below: Condition 1 (Standard Intervention): Branch I: Participants assigned to the control condition will receive a FIT kit and the standard invitation letter to participate in free screening. Condition 2 (Time Guideline): Branch II: Participants will receive a FIT kit and invitation letter to participate in free screening with a 1-week time restriction. Branch III: Participants will receive a FIT kit and invitation letter to participate in free screening with a 3-week time restriction. Condition 3 (Time Guideline + Incentive): Branch IV: Participants will receive a FIT kit and invitation letter to participate in free screening requesting they return the kit within 1-week for a "higher" monetary incentive or within 3 weeks for a "lower" (half of the higher) monetary incentive. Branch V: Participants will receive a FIT kit and invitation letter to participate in free screening requesting they return the kit within 1-week for a "higher" (same as lower in Branch IV) monetary incentive or within 3 weeks for a "lower" (half of the higher) monetary incentive. Participants with a normal test result will receive a personal letter confirming this with invitations to complete a repeat screening in subsequent year(s). Participants receiving an abnormal FIT result will be navigated to complete a diagnostic colonoscopy. Participants continuing in the screening program in subsequent years will receive letters emphasizing the importance of repeat screening to prevent adverse CRC outcomes.

Surgery has been available for the treatment of pulmonary metastases in metastatic colorectal cancer and promising overall survival was observed in retrospective studies with selected patients. This study investigated whether the preoperative FDG- PET/CT scan influences survival in this patient group. Furthermore, we tried to identify other prognostic factors associated with overall survival and progression-free survival.
