Abstract:
Objective To investigate the risk factors for the prognosis of radical resection in elderly patients with colorectal cancer.Methods A total of 416 patients with colorectal cancer aged over 65 years were analyzed retrospectively,who came from Peking University First Hospital and Beijing Hospital from July 2008 to July 2011.Survival analysis was conducted by Kaplan-Meier and the survival rate was compared by Log-rank method.Multivariate analysis was conducted to analyze the prognostic factors by Cox regression.Results In this group of patients,the age was(74.3 ±5.4)years,and the post operative 5-year survival rate were 84.5％,77.3％,48.2％ respectively for staging Ⅰ,Ⅱ,Ⅲ patients.Univariate analysis showed that age,ASA score,co morbidity,preoperative hypohemia,preoperative hypoalbuminemia,postoperative complications,elevated preoperative carcinoembryonic antigen (CEA),intraoperative blood loss,perioperative blood transfusion,vascular cancer embolus,nerve invasion,depth of invasion,lymph node metastasis,tumor TNM stage and adjuvant therapy were correlated with the prognosis.Multivariate analysis showed that age ≥75 years,co morbidity,postoperative complications,preoperative albumin＜30 g/ L,depth of invasion,and lymph node metastasis,tumor TNM stage and adjuvant therapy were the independent risk factors for prognosis.Conclusions The risk factors for prognosis after radical resection in elderly patients with colorectal cancer include age≥75 years,co-morbidity,postoperative complications,preoperative albumin ＜30 g/L,depth of invasion,and lymph node metastasis,tumor TNM stage and adjuvant therapy.
