ABSTRACT
To investigate the relation between AR and the survival period in patients with colorectal cancer.Multiple variance Cox regression analysis was performed between AR, DNA and CEA in tumor tissues and normal mucosa, and other host and tumor characteristics, such as gender, age, location of tumor (colon, rectum), degree of differentiation (high, middle, low), Dukes stage (A,B,C,D) and the survival period, in 30 colorectal patients. There were no significant differences with regard to gender, age, histological differentiation, AR, DNA and CEA levels in tumor tissues. Rectal carcinoma had poorer prognosis than colon carcinoma ( P
ABSTRACT
To sum up the experiences and results of surgical treatment for recurrent rectal carcinoma after rectectomy, pelvic exenterations were carried out for 49 patients with the disease and the survival rate was estimated. No death occurred in our group. The resect rate was 91 8%, and the operative complication rate was 12 2%. The 3 year survival rate was 85 5%, and the 5 year survival rate was 60 6%. Pelvic exenteration can improve the survival rate for recurrent rectal carcinoma after rectectomy. Urinary reconstruction and repair of pelvic peritoneum are important for reducing operative complications.
