Active clinical trials for "Colorectal Neoplasms"

To explore the efficacy and safety of Cetuximab in combination with dabrafenib and Tislelizumab in BRAF mutated treatment of advanced colorectal cancer

This study investigates if circulating tumor DNA (ctDNA) and other tumor-related molecules/chemicals released in the blood can help doctors predict if colorectal cancer may come back or spread. Tumors shed DNA and other cancer related chemicals into the blood that can be identified and studied further to provide information about the cancer. Information gathered from this study may help researchers better understand if ctDNA found in the blood can predict whether colorectal cancer may come back or spread.

The purpose of this study is to find out how cancer treatments (chemotherapy and/or radiation therapy) affect reproductive and sexual health in people with early onset colorectal cancer. The study researchers will observe and track changes in hormone levels and in sexual and reproductive health in people with early onset colorectal cancer. This information will help researchers know more about how cancer treatments affect reproductive and sexual health, including the ability to have children (fertility).

This is a randomized controlled trial investigating efficacy of electrochemotherapy for early colorectal cancer

The CORRECT - MRD II study will prospectively enroll patients who have undergone complete surgical resection for stage II or III colorectal cancer. Patients will be followed for a minimum of 3 years and up to 5 years for recurrence.

Early detecting and removing of colorectal advanced adenomas can reduce incidence of colorectal cancer. In order to reduce the incidence of colorectal cancer, improve the early diagnosis of colorectal cancer, the investigators conducted this study to explore diagnostic accuracy of fecal immunochemical test in colorectal cancer screening population.

Bowel cancer is the third most common cancer occurring in the UK. Treatment usually involves surgery, often with chemotherapy or radiotherapy. In some cases radiotherapy can be used instead of surgery, especially if surgery may cause a higher risk of symptoms or a colostomy bag. Currently, the medical team collects information on patients' symptoms before and after treatment by direct questions in a clinic setting. It's recognised that patient-reported symptoms often differ from doctor-documented symptoms. This leads to inaccuracies in doctors' descriptions of the effects of cancer or treatment to patients. Patients told us an accurate description of expected symptoms is important when they are choosing their treatment. Patient-Reported outcomes measures (PROMs) may help us identify what affects the QoL after treatment and develop ways to improve it. The primary aim of the trial is to evaluate whether patients find it acceptable to use electronic data collection to assess their symptoms. Many bowel cancer patients are elderly and they may find electronic data system collection more challenging. The secondary aim is to identify which symptoms impact QoL. This will lead to the development of treatments to manage these symptoms which will be assessed in CITRuS2. All patients diagnosed with bowel cancer are entered into the colorectal database to determine the effectiveness of cancer treatments and outcomes. Participants will electronically answer questionnaires at study entry and during follow up. The questions are related to health and well-being with a holistic approach. The questions will take approximately 45 minutes to answer the first time and then 15 minutes thereafter. Following consent, participants gain access to their clinical details on the database. Then they can use a computer, laptop, tablet or smart phone to access a webpage and answer questions at monthly intervals over a 2 year period. Email reminders will be sent to prompt log on. This may help discover how bowel cancer and its treatment affect patients and their lives. This may help doctors describe the effects of treatment more accurately to future patients. It may also help doctors identify which patients need extra help or support through their treatment. Electronic data may allow patterns to be identified that may not be seen by doctors until a later stage. This may enable earlier treatment resulting in less time with symptoms, which could be physically and economically beneficial.

Extensive preclinical evidence suggests that short-term fasting and fasting mimicking diets (FMDs) can protect healthy cells and render cancer cells more vulnerable to chemotherapy and other therapies. However, fasting is difficult for the old and frail subjects.Therefore, FMDs may be more suitable for postoperative dietary intervention in cancer patients. Colorectal tumors have high glucose consumption, which makes tumor cells very sensitive to changes in nutritional metabolism of the surrounding environment (such as diet restriction / fasting). Previous studies have shown that cyclic FMDs are safe and feasible for cancer patients receiving chemotherapy alone. However, the effects of the FMD in patients under radical surgery for colorectal cancer have not been evaluated so far. This study aims to evaluate the impact of FMDs on postoperative recovery and outcomes of patients with colorectal cancer.

This is an open-label, multicenter, randomized phase 2 study evaluating the efficacy and safety of fruquintinib plus capecitabine versus capecitabine as maintenance therapy for metastatic colorectal cancer after first-line treatment. Patients who have already achieved disease control (including CR/PR and SD) after ≥6 cycles of standard first-line induction treatment, and are still unresectable would be assigned into 2 maintenance treatment groups by randomization in a 1:1 ratio to receive fruquintinib + capecitabine or capecitabine. All patients will be treated until progressive disease, death from any cause, unacceptable toxicity or informed consent withdrawal.

This is an observational study in a clinical setting to estimate the prevalence of advanced colorectal neoplasia (ACN) at colonoscopy in those with a history of low or high risk polyps or a family history of CRC/polyps and to verify the test performance characteristics of FIT in these populations. Using this information, a risk prediction model will be developed to help guide the choice between FIT and colonoscopy in the ongoing surveillance or screening of patients.
