Values are presented as percentages and the number of subjects (n) in each classification
T1: tumor invaded submucosa; T2: tumor invaded muscularis propria; T3: tumor invaded subserosa; T4: tumor invaded visceral peritoneum
N0: no regional lymph node involvement; N1: 1-3 regional lymph node involvement; N2: more than 4 regional lymph node involvement
M0: no distant metastasis; M1: distant metastasis
