Closest margin: margin, cm from tumor.
Distance to deep margin (required for transanal disk excisions): mm from tumor.
Check if positive margins were seen GROSSLY
* positive radial/mesenteric margin defined as invasive tumor <= 0.1 cm from margin** applies only to trans-anal disk excisions
No lymph nodes sampled No tumor identified in lymph nodes. Metastatic carcinoma identified in of nodes. Lymph node search performed by two people No tumor deposits are identified. Tumor Deposits present. Number identified:
Multiple Primary Tumors (m) Recurrent Tumor (r) Post-treatment Staging (y)
Histologically normal appendix Tubular adenomas Hyperplastic polyps Chronic ulcerative proctocolitis Crohn disease Dysplasia arising in inflammatory bowel disease
Original H&Es and deeper sections are examined. Case reviewed in departmental conference. Pankeratin immunostain used in evaluation. Lymph node search performed by two people Although at least 12 nodes were identified, extra methods were utilized that my alter the statistical validity of "12 nodes." Clinical correlation is recommended for the possible benefit of chemotherapy.
