Predictive value of CEA and CA19-9 for recurrence in stage Ⅱ-Ⅲ colon cancer
摘要
背景与目的:Ⅱ~Ⅲ期结直肠癌患者根治术后约有1/3出现复发转移,影响患者预后。该研究旨在评估癌胚抗原(carcinoembryonic antigen,CEA)和糖类抗原19-9(carbohydrate antigen 19-9,CA19-9)对Ⅱ~Ⅲ期结肠癌患者根治术后复发的预测价值。方法:回顾性分析2012—2013年收治的168例Ⅱ~Ⅲ期结肠癌患者的临床病理和随访资料,均接受根治术,根据术前和术后血清CEA和CA19-9结果将患者分成3组。结果:CEA(H)组的无复发生存率显著低于CEA(HN)组和CEA(N)组(7.4% vs 52.5% vs 75.0%,P=0.000),CA19-9(H)组的无复发生存率显著低于CA19-9(HN)组和CA19-9(N)组(7.1% vs 50.0% vs 61.9%,P=0.000);COX比例风险回归模型多因素分析显示,CEA(H)组、CEA(HN)组、CA19-9(H)组及淋巴结转移是Ⅱ~Ⅲ期结肠癌根治术后复发的独立危险因素。结论:血清CEA和CA19-9可以作为Ⅱ~Ⅲ期结肠癌患者预测复发、协助TNM分期判断预后的重要指标。
Abstract
Background and purpose: About one third of patients with stage Ⅱ-Ⅲ colorectal cancer suffer a recurrence after radical surgery
which affects the prognosis of patients. This study aimed to evaluate the value of serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) in predicting and monitoring the recurrence of stage Ⅱ-Ⅲ colon cancer patients after radical surgery. Methods: The clinicopathological and follow-up data collected from 168 patients who underwent radical resection of stage Ⅱ-Ⅲ colon cancer from 2012 to 2013 were analyzed retrospectively. The patients were divided into 3 groups based on the results of serum CEA and CA19-9 before and after surgery. Results: The recurrence-free survival rate in the CEA (H) group was lower than in the CEA (HN) group and CEA (N) group (7.4% vs 52.5% vs 75.0%
P=0.000). The recurrence-free survival rate in the CA19-9 (H) group was lower than in the CA19-9 (HN) group and CA19-9 (N) group (7.1% vs 50.0% vs 61.9%
P=0.000). Multivariate analysis showed that CEA (H) group
CEA (HN) group
CA19-9 (H) group and lymph node metastasis were independent risk factors for recurrence after radical resection in stage Ⅱ-Ⅲ colon cancer patients. Conclusion: Serum CEA and CA19-9 can be used as predictive factors for recurrence in stage Ⅱ-Ⅲ colon cancer patients and assist in the TNM staging for prognosis of the patients.
