简要总结
The main purpose of this study is to investigate whether magnetic ressonance imaging (MRI) can be used in treatment planning with assessment of diagnostic accuracy. With the inclusion of 150 patients the study will investigate whether MRI is useful and better than CT scanning in patients with colon tumors. And also if MRI is useful after neoadjuvant treatment.
详细描述
Colon cancer is a frequent disease in Denmark with over 3200 new cases and about 1350 deaths per year.
CT scanning is currently the national standard method for determining the stage of disease planning for treatment. CT scan can sufficiently distinct between minor and advanced colon tumors. Prevalence of advanced tumors was well over 40% in the CT study from Vejle Hospital in 2013. Sensitivity and specificity of detection of advanced colon tumors in the CT study was approx. 70% and 80%, respectively. A small MRI pilot study showed higher sensitivity and specificity of 89% and 96%, respectively.
MRI scan is currently performed in most patients with rectal cancer, which has resulted in better treatment planning and increased survival. MRI scan of the rectum is documented with higher accuracy than CT scan. There has been reluctance to introduce MRI scan in patients with colon cancer, as the colon has more peristalsis than the rectum, and movement of the bowel can result in image quality reduction in MRI. However, in recent years MRI has become faster and thereby less sensitive to movements.
MRI scanning may in the future help to select the patients who will benefit from neoadjuvant treatment. In addition, with MRI it is possible to perform MRI diffusion measurements of the tumor, which gives an estimate of the tumor's cell density. It will also be possible to investigate whether this changes the MRI diffusion restriction during the neoadjuvant treatment.
This study is prospective and uses state of the art equipment with a 3 tesla MRI unit.
