Extramural extension as indicator for postoperative adjuvant chemotherapy in Stage IIA (pT3N0) colon cancer.
Bottom Line: The optimal prognostic cut-off point of the DEE for oncologic outcomes was statistically determined.The pT3b was the most powerful independent risk factor for postoperative recurrence (P = 0.0324, HR: 3.04, 95% CI: 1.098-8.408), and was significantly correlated with distant metastasis (P = 0.0161 HR: 5.19, 95% CI: 1.765-15.239).Postoperative adjuvant CMT may be indicated for patients with pT3b.

Mentions: As shown in Figure 3, the recurrence-free 5-year-survival rate was significantly lower in patients with pT3b than in patients with pT3a (81.5% vs. 95.4%, P = 0.0003, HR: 4.71, 95% CI: 1.875–11.849). In addition, the cancer-specific 5-year-survival rate in patients with pT3b was significantly lower than that in patients with pT3a (85.9% vs. 97.4%, P = 0.0007, HR: 5.84, 95% CI: 1.831–18.632) as shown in Figure 4.
