From: Utility of the sentinel node concept for detection of lateral pelvic lymph node metastasis in lower rectal cancer

Tumor depth    upper-middle (n = 22)   lower (n = 36) P-value
clinical T1 (n = 14) 0 (0/7) 0 (0/7) 0.0074
T2–4 (n = 44) 13.3% (2/15) 37.9% (11/29)  
pathological T1 (n = 18) 0 (0/8) 10% (1/10) 0.0032
T2–4 (n = 40) 14.3% (2/14) 38.5% (10/26)
