约6％～10％直肠癌已属局部进展期，为根治目的常需整块切除肿瘤连同膀胱、远端输尿管和生殖器官，5年生存率为33％～50％，需要明确影响预后的因素。作者回顾性复习病人的年龄、性别、盆腔内脏去除术（PE）的术式、肿瘤浸润范围、辅助治疗、肿瘤DNA倍性和S相分数等临床病理因? About 6% to 10% of rectal cancer has been locally advanced. For the purpose of radical resection, it is often necessary to remove the tumor together with the bladder, distal ureter and reproductive organs. The 5-year survival rate is 33% to 50%, and the factors that affect the prognosis need to be clearly identified. .
