Comparison among patients with G1-2 tumor and no bowel resection (blu line), patients with G-1 tumor and bowel resection (green line), patients with G3 tumor and no bowel resection (red line), and patients with G3 tumors and bowel resection (black line). G1-2 without bowel resection (62/199 31.2%): median PFS (A) not reached (mean 91.2), median OS (B) not reached (mean 103.9). G1-2 with bowel resection (14/199 7.0%): median PFS (A) 25,0 months (95% C.I. 0–51.8), median OS (B) 46.0 months (95% C.I: 0–106.3). G3 without bowel resection (77/199 38.7%): median PFS (A) 27,0 months (95% C.I. 20,3-33.7), median OS (B) 85.0 months (95% C.I. 51,6-116.3). G3 with bowel resection (46/199 23.1%) median PFS (A) 27.0 months (95% C.I. 11,4-42.6) median OS (B) 38.0 months (95% C.I. 28,8-47.2). Patients with G1-2 tumor and without bowel involvement had a better prognosis for both PFS and OS (p < 0.01). Patients with G3 tumor without bowel involvement had a better OS versus G3 patients with bowel involvement (p < 0.05).
