Actionable Nuggets for SCI (3rd ed., 2016)
The incidence of colorectal cancer in individuals with spinal cord injury (SCI) is similar to the general population; however, diagnosis of these tumours often occurs at an advanced stage in the SCI population. Sensory deficits and motor limitations can prevent individuals with SCI from recognizing symptoms that would be evident to individuals who are neurally intact. The high prevalence of rectal bleeding among individuals with SCI means that it is not a good indicator for screening; instead routine screening for colorectal cancer is essential.
Initiate colorectal cancer screening for patients with SCI using the same principles as those for the general population.
Evidence-based Best Practice:
As with the general population, individuals with SCI between the ages of 50 and 74 years and with a negative family history should be screened for colorectal cancer according to current Canadian guidelines:
1) Fecal occult blood test (FOBT) every 2 years, or
2) Flexible sigmoidoscopy every ten years.
Individuals over 75 years of age should not be screened.
Screening with FOBT can reduce mortality from colorectal cancer by 15-33%. Screening with sigmoidoscopy can reduce colorectal cancer mortality by up to two thirds for lesions within reach of the sigmoidoscope.
Colonoscopy is not recommended to screen for colorectal cancer. Preparation for colonoscopy is a significant ordeal for someone with neurogenic bowel, to the extent that it is often incomplete and produces compromised results. It is recommended only in the case of a positive screening test (above), because it permits direct visualization of the large bowel in its entirety. For patients with SCI, consultation with the gastroenterologist may be required.
