Active clinical trials for "Colorectal Neoplasms"

This prospective observational study will evaluate the safety and efficacy of Avastin (bevacizumab) in patients with metastatic colorectal cancer. Data will be collected from patients receiving Avastin in combination with chemotherapy according to registered indication in routine clinical practice.

Aim of the study is to increase the proportion of indicated patients with colorectal cancer undergoing adjuvant chemotherapy following surgical resection through an optimized symptom management and logistical support.

The aim of this double-blinded prospective randomised trial is to explore the potential benefits of early postoperative administration of Synbiotics (combination of prebiotics and probiotics) to patients who have undergone colectomy for cancer. The patients are randomised to either synbiotics or placebo administration at the day they are able to tolerate po liquid diet and for 15 days thereafter. Primary end points of the study will be: Assessment of gastrointestinal function-related quality of life at 1, 3 and 6 months postoperatively by the use of the validated questionnaire GIQLI (Gastrointestinal Quality of Life Index) Secondary end points will be: -Assessment of functional bowel disorders (diarrhea, constipation, etc) at 1, 3 and 6 months postoperatively based on the respective domains of the validated instrument EORTC QLQ-C30

The propose of this study is to assess the effect of general practitioner's involvement on first patients' solicitation in screening for colorectal cancer by testing for faecal occult blood (FOBT).

RATIONALE: Questionnaires that assess symptoms caused by cancer and cancer therapy may help improve the ability to plan treatment for patients with invasive cancer to help them live longer and more comfortably. PURPOSE: This clinical trial is studying symptoms caused by cancer and cancer therapy in patients with invasive breast, lung, prostate, or colorectal cancer.

RATIONALE: Determination of genetic markers for colorectal cancer may help doctors to identify patients who are at risk. PURPOSE: Genetic testing study of patients and families with a history of colorectal cancer to identify patients who are at risk of developing colorectal cancer.

A prospective, single center, cohort study for surveillance of metabolic parameters in patients who will receive chemotherapy after surgical resection of colorectal cancer

Molecular imaging with positron emission tomography (PET) using [18F] fluorodeoxyglucose (FDG) has been suggested as an early, sensitive marker of tumour response to anticancer drugs by monitoring the changes in glucose metabolism in tumours. Recently, FDG-PET has shown to be highly sensitive in detecting early response in other tumours. In this study, the investigators will prospectively investigate the role of early FDG-PET (at day 7 and week 6) in outcome prediction.

When used with a different radioactive tracer called FMISO, a PET scan can find areas of low oxygen in the tumor. We think that having areas of low oxygen is a reason why some tumors are hard to treat with radiation. In a past study, FMISO PET scans were performed in 6 patients with rectal cancer that could not be operated on and that had spread to other areas. In this group of patients, FMISO PET scans were able to find the low oxygen areas in their tumors. But this study included only a few patients. In the present study, we want to use FMISO PET scans in patients who have tumors that can be operated on. This group of patients will have radiation, chemotherapy or both before they have their surgery. We want to see if FMISO PET can find low oxygen areas in this distinct group of patients.

This clinical study will investigate the utility of PET imaging with [89Zr]Panitumumab for imaging of EGFR expression in newly diagnosed colon cancer patients to assess lymph node involvement. If promising, this data will be used to design larger trials.
