RESUMO
After almost 50 years of data analysis, screening for colorectal cancer has proven to be an effective tool in reducing colorectal cancer mortality. However, implementing the optimal strategy represents a challenge for many healthcare facilities around the world. There is much discussion regarding how screening should be done, the optimal tools that should be used, and the proper timing for screening procedures. Another essential step is to maintain the adherence of patients to screening programs. Also, the recommendation for lowering the age to initiate screening is in progress, as there is an increase in colorectal incidence in people born after 1970.

The most common hematologic complication of inflammatory bowel disease (IBD)--ulcerative colitis and Crohn's Disease is anemia. Anemia in patients with IBD may be a result of iron, vitamin B12 or folate deficiency; anemia of chronic disease and hemolytic anemia are other causes in these patients. Factors contributing to the development of anemia include chronic gastrointestinal blood loss, vitamin B12 malabsorption secondary to terminal ileitis, folate deficiency as a result of sulfasalazine therapy. Approximately 30% of patients with IBD have hemoglobin levels below 12 g/dl. The risk of developing anemia relates to disease activity, given that blood loss and inflammatory anemia are triggered by intestinal inflammation. In the management strategy of IBD patients with anemia it is important to distinguish between the different types of anemia in order to decide an appropriate manner of treatment.
