背景大部分患者行胰腺癌(PC)切除时目前尚未发现的微小转移灶其实已经存在了。传统的以影像学为依据的术前评估方法并不能发现微小转移病灶。目的以胰腺癌胰腺十二指肠切除(PD)患者的术前一般资料特征为基础开发出一种用于预测复发及死亡的预测模型。方法我们搜集1997～2007年
Background Most micrometastases that have not been found in pancreatic cancer (PC) resection exist in most patients. Traditional imaging-based preoperative assessment methods do not detect micrometastases. Objective To develop a predictive model for the prediction of recurrence and death based on the preoperative general data features of patients with pancreaticoduodenectomy (PD) of pancreatic cancer. Methods We collected from 1997 to 2007
