Cr-POSSUM 评分系统对直肠癌手术患者的预测价值.

Objective To evaluate the predictive value of Cr-POSSUM scoring systems in patients with rectal cancer after surgery. Methods 276 patients who underwent surgery with colorectal malignant neoplasms were divided into two groups depending on Cr-POSSUM total scores. Scores 17 points or less were defined as low-risk patients, scores more than 18 points were defined as a high-risk patients. The predicted results were compared with the actual situation by receiver-operating characteristic curve （ROC curve） and the ratio of expected mortality and obseved mortality to evaluate the accuracy. Results In the comparison of patients with high-risk group and low risk group， age， PS score， OS scores， postoperative bleeding and mortality in 30 day after surgery had a statistically significant difference（p P＜0.05） . Conclusion Cr - POSSUM can accurately predict the postoperative mortality of patients with rectal cancer. [ABSTRACT FROM AUTHOR]
