Active clinical trials for "Colorectal Neoplasms"

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.

The risk of CRC in families of patients with CRC is well established, but it is less well-defined for families of patients with adenomas. Screening recommendations to families when an index subject has an adenoma on colonoscopy are not clear. Previous studies demonstrating an increased CRC risk in close relatives of subjects with adenomas were mostly limited by the lack of a suitable comparison group, did not offer colonoscopy to all relatives or did not have verification on true status of adenoma history in the relatives. A systematic review has reported that most studies cited for risk of CRC in relatives with adenomas have not addressed the intended question. Currently International guidelines recommended screening colonoscopy in close relatives and at a younger age when there is a proband with an adenoma, however this recommendation has not been fully supported by all societies due to the lack of robust evidence. This gap in knowledge highlights the need of well-designed and adequately powered studies to estimate the risk of colorectal neoplasms in subjects who have first-degree relatives with adenomas. Up to 30% of average risk asymptomatic individuals 50 years or older will have at least one adenoma. Based on current guidelines, nearly half the population will be counseled to undergo a colonoscopy from 40 years old based on a positive family history of adenoma. This will have enormous burden on the healthcare system if screening is implicated in all these individuals. Secondly, not all adenomas carry the same risk. Large or villous adenomas are associated with a nearly 70% increased risk of CRC in first degree relatives (FDR) whereas small adenomas may be associated with a modest increased risk 19. It is therefore important to determine the risk of colorectal neoplasms in families of subjects with non-advanced adenomas to justify more intensive screening in these individuals. Investigators hypothesize that first-degree relatives of patients with non-advanced adenoma have an increased risk of both CRC and adenomas. Investigators aim to quantify this risk, and to identify other individual patient or neoplasm characteristics that may contribute to this increased risk. In addition, Investigators aim to determine molecular alteration profiles of colonic adenoma in siblings of patients with advanced neoplasm.

Although there is evidence for reducing complication rate and improving recovery after the implementation of Enhanced Recovery After Surgery (ERAS) protocols into colorectal surgery, most published papers include patients undergoing open resections. The aim was to analyse factors affecting recovery and length of stay (LOS) in patients after laparoscopic colorectal surgery for cancer combined with ERAS protocol.

To assess the feasibility and effectiveness of a program in L-IBD patients using CE targeted biopsies

This study tests biopsy and tissue from patients who have been treated for primary rectal cancer at the Royal Marsden Hospital between 2011 and 2013, who have an mrTRG score at post-chemoradiotherapy MRI. It is a retrospective pilot study to determine the apoptotic and proliferative index count pre and post chemoradiotherapy.

Contribution to the study of oxidative stress markers in laparoscopic vs open colectomy for colorectal cancer

This is a multicenter translational study to understand therapeutic resistance in patients undergoing first-line chemotherapy (FOLFOX/Avastin, or FOLFIRI/Avastin) for metastatic colorectal cancer. Tissue samples from liver metastasis will be collected and banked before the start of chemotherapy and at the time of progression. Additionally, blood samples will be drawn monthly and stored in the tissue biobank.

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of curcumin may prevent or treat colorectal cancer. PURPOSE: This phase I trial is studying the side effects of curcumin in preventing colorectal cancer in patients undergoing colorectal endoscopy or colorectal surgery.

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in peptides and proteins and identify biomarkers related to cancer. PURPOSE: This research study is looking at blood samples from patients with malignant melanoma, metastatic breast cancer, advanced lung cancer, pancreatic cancer, or colorectal cancer.

This study is designed to measure and compare the inflammatory response in laparoscopic and open colon cancer surgery
