Active clinical trials for "Colorectal Neoplasms"

Conventional multi-port laparoscopic surgery (CL) is now a standard approach to colorectal resections, due to it's short-term benefits over conventional open surgery. In recent years, several studies have demonstrated that - in suitable patients - single-port access surgery (SPA) has similar clinical outcome compared to CL, with additional cosmetic benefits. It remains, however, unclear whether the trauma of surgery is also less for SPA compared to CL. In this study, the investigators aim to randomise patients who are deemed suitable for SPA surgery to either SPA approach, or CL; in addition to clinical outcomes including length of operating time, post-operative pain scores, complications, quality of life indicators and cosmetic appearance, the investigators aim to compare the physiological response to trauma through biochemical markers (including C-reactive protein, White Blood Cell count) and cytokine expression (i.e. Interleukins IL-6 and IL-8). Patients will be analysed according to intention-to-treat analysis, with 25 patients in the SPA and 25 patients in the CL group. The patients will be operated by surgeons proficient in both CL and SPA surgery, and followed-up for the duration of their hospitalisation as well as at their routine out-patient visits, using questionnaires.

The aim of this systematic review is to compare intracorporeal (IA) versus extracorporeal anastomosis (EA) after laparoscopic right hemicolectomy for cancer.

The purpose of this study is to diagnose possible synchronous carcinomas and polyps with magnetic resonance (MR) colonography in patients booked for operation because of carcinoma in the descending or sigmoid colon, where a preoperative full colonoscopy is not possible. Two days before colonography, patients ingest a 200 ml Barium sulfate solution four times a day, which will render fecal masses "invisible" on the following MR colonography. The study is primarily a feasibility study with altered operative strategy as a secondary end-point. Gold standard is colonoscopy and operation.

The aim of the study is to test the hypothesis that a chromoscopy colonoscopy is able to increase by 50 % the number of pre-cancer lesions or early cancer detected in patients with HNPCC syndrome, compared to a routine colonoscopy without chromoscopy.

Primary endpoint of the study is to prove the superiority of an adjuvant therapy with oxaliplatin/ capecitabine until the first occurrence of appearance of a tumour. Occurrences in the meaning of this study are the appearance of a relapse of the tumour, of metastases, of a second tumour or death of any reason.

In Canada, over 102,900 men are diagnosed with cancer each year. Of these, 81,000 are diagnosed with colorectal cancer and an estimated 65% are expected to survive the disease for at least 5 years. Men who have completed treatment for colorectal cancer face many adverse physical, cognitive, psychological, and social effects. The Wellness Beyond Cancer Program at The Ottawa Hospital is a cancer survivorship program that helps people who have completed treatment for cancer, including men diagnosed with colorectal cancer, manage these effects. The Wellness Beyond Cancer Program does this through education and referral to supportive care services and programs offered throughout the city of Ottawa. Group-based physical activity programs are one of the varied services and programs available to adults diagnosed with cancer in Ottawa. Such programs are offered through the Ottawa Regional Cancer Foundation (http://www.ottawacancer.ca) and Breast Cancer Action Ottawa (http://bcaott.ca). Research on these programs show that group-based physical activity can improve disease and treatment-related effects while promoting overall quality of life amongst women with cancer. However, few of these programs have targeted men, even though their needs and preferences have been shown to be very different from women. While men diagnosed with colorectal cancer might also benefit from group-based physical activity programs offered in the community, it is not known if such programs would effectively reach them and what the impact would be on their quality of life after cancer treatment. It is believed that a men's group-based walking program could be an effective way to reach men and promote quality of life after cancer treatment. Therefore, a sustainable 8-week group-based walking program was developed. This project will seek to explore the feasibility and potential benefits of the program among men who have completed treatment for colorectal cancer and who are referred to the program from staff at the Wellness Beyond Cancer Program in a prospective single-arm trial.

This study is for patients with metastatic colorectal cancer who are candidates for resection of metastases. This study will be conducted sequentially with 2 cohorts: 1.) Monotherapy Cohort and 2.) Combination Cohort Pre-metastatectomy Monotherapy Cohort: The first 10 subjects will receive Atezolizumab 840 mg IV on Day 1 and Day 15 of each 28-day cycle. Combination Cohort: The next 15 subjects will receive Atezolizumab 840 mg IV on Day 1 and Day 15 and Cobimetinib 60 mg PO on Days 1-21 of each 28-day cycle. Note: Cobimetinib must be held for the 7 days prior to metastatectomy. All subjects will be treated for 2 cycles (8 weeks) prior to metastatectomy Metastatectomy Subjects will undergo liver metastatectomy within 42 days of completion of Cycle 2 of pre-metastatectomy treatment. No study treatment is administered while the patient is healing after surgery. Post-metastatectomy Once the patient has healed from the surgery, adjuvant treatment may be administered at the discretion of the treating physician. Restaging following standards of care for this setting.

The Institute of Image-Guided Surgery (IHU) of Strasbourg is a translational research Institute aiming to develop hybrid surgery techniques. The IHU-SPECTRA research unit, entirely dedicated to the development of fluorescence-guided surgery, was set up to test several innovations as part of a large-scale project (ELIOS: Endoscopic Luminescent Imaging for Precision Oncology Surgery), funded by the ARC Foundation for Cancer Research. The proposed research protocol is part of the ELIOS project and targets in particular colon tumours. The Holy Grail in oncology surgery is the radical removal of cancer cells in order to reduce the rate of tumour recurrences and increase the tumour's free survival. The administration of a tumour-specific antibody, which fluoresces in the Near-Infrared ranges and which could be univocally recognized at a tumour cellular level, could provide a rapid and accurate evaluation of radical tumour removal. The University Medical Center Groningen (UMCG) has developed a fluorescent tracer coupling Bevacizumab (which targets the Vascular Endothelial Growth Factor = VEGF) with a fluorescent dye, the IRDye800. The initial human results are very promising and no adverse events linked to the fluorescent molecule have been reported. In parallel, an alternative optical technique that does not require the use of a fluorophore, the Hyperspectral Imaging (HSI), is a relatively new method used in image-guided and precision surgery. The company Diaspective Vision GmbH (Pepelw, Germany) produces a HSI camera, the TIVITA system, enabling to obtain spectral information from the tissues. The main advantage of HSI over fluorescence imaging is in that it is a contrast-free imaging and intrinsically quantitative although it does not provide real-time videos. Another innovative optical imaging technology available at the IHU is FF-OCT (Light-CT Scanner, LLTechSAS, Paris, France) which allows non-destructive and high-resolution optical biopsy without tissue treatment. The working hypothesis is that molecular fluorescence enhanced-reality allows greater precision in the differentiation of tumour tissue and healthy tissue in patients with colorectal cancer compared to the immunohistochemistry conventionally used in anatomopathology. In parallel, this technique will be compared to hyperspectral imaging (HSI TIVITA system) and optical imaging (FF-OCT system), two potentially advantageous methods for the detection of tumour tissue.

The primary hypothesis is that a comprehensive transitional care program based on the premise of a patient-centered medical home versus routine care reduces emergency room visits and hospital readmissions without increasing costs among cancer patients undergoing surgery at a large safety-net hospital.

The purpose of this study is to assess if curcumin, a commonly used food spice, can regress colorectal adenomatous polyps in patients with familial adenomatous polyposis, an inherited form of colorectal cancer.
