Signs and symptoms may include blood in the stool, a change in bowel movements, weight loss, and fatigue.. Staging and treatment paradigms for this disease were developed primarily following those for colon cancer . However, the pathogenetic background in pediatric cases is different from adults and usually involves mismatch repair gene mutations or familial polyposis syndromes. Grading based on worst area; Leading front of invasion excluded from grading; It is acceptable to grade simply as Low vs. High grade; Applies only adenocarcinoma NOS See special types for relevant grading criteria (mucinous, signet ring, medullary, squamous) Low grade â¥50% gland forming; Well differentiated ...
