Lymph node positive colorectal carcinoma

Lymph node positive colorectal carcinoma refers to epithelial malignancy originating in the colon or rectum that has metastasized to regional lymph nodes, pathologically categorizing it as stage III disease in the absence of distant metastases Pathophysiologically, malignant cells breach the intestinal basement membrane, penetrate through layers of the bowel wall, and enter the regional lymphatic drainage, resulting in metastatic tumor deposits within paracolic, mesocolic, or mesorectal nodes It...

This condition affects the gastrointestinal and lymphatic systems, occurring primarily in adult populations

This condition affects the gastrointestinal and lymphatic systems, occurring primarily in adult populations It is clinically defined by histopathologic evidence of one or more involved regional lymph nodes (N1 or N2 classification), representing an elevated risk of systemic recurrence that typically guides the use of adjuvant therapy
