When to use abdominal CT for colon cancer?

Aim: To assess the frequency of undetected colon cancer on conventional abdominal CT and to evaluate the imaging features that are characteristic of those cancers.

Can a CT scan detect undetected colon cancer?

Undetected tumours were shorter than those detected (original reader: 33.2±11.9 versus 51.4±18.2 mm; study reader: 32.5±9.6 versus 61.3±23.4 mm; p<0.001). Conclusion: Colon cancer is undetected in 20% of abdominal CT examinations in patients subsequently proven to have colon cancer at colonoscopy.

How are radiologists blinded to the location of colon cancer?

Two radiologists (“study readers”), blinded to the tumour location, independently performed interpretations oriented for colon cancer detection. The study readers analysed the imaging features of detected tumours (tumour shape, length, maximal wall thickness, free fluid, fat stranding, vascular engorgement, stenosis, and lymphadenopathy).

What are the imaging features of colon cancer?

The study readers analysed the imaging features of detected tumours (tumour shape, length, maximal wall thickness, free fluid, fat stranding, vascular engorgement, stenosis, and lymphadenopathy). Imaging features of the cancers undetected by the original readers were evaluated. Results: The study included 127 patients.

Who are the authors of early colorectal cancer?

How is the diagnosis of colorectal cancer made?

In colorectal cancers, although flat and depressed-type lesions are found by regular endoscopic view, magnification and pit-pattern observation are vital parts of the precise diagnosis of the lesion.

What are the statistics for colorectal cancer screening?

Use of Colorectal Cancer Screening Tests The percentage of U.S. adults aged 50 to 75 years who were up-to-date with colorectal cancer screening increased 1.4 percentage points, from 67.4% in 2016 to 68.8% in 2018. This represents an additional 3.5 million adults screened for colorectal cancer.

Is there a difference between colon and rectal cancer?

In the picture above you can see where the colon and rectum are inside the body. In most cases, colon and rectal cancers grow slowly over many years. We know that most of those cancers start as a growth called a polyp. Taking out the polyp early may keep it from turning into cancer. Are there different kinds of colon and rectal cancers?
