摘要: 本研究旨在探讨在胃癌分期诊断及化疗疗效预测中应用多层螺旋CT (MSCT)的价值。选取100例胃癌患者进行本次研究,患者均接受新辅助化疗治疗,并行MSCT检查,根据化疗的疗效分组,有效组患者39例,无效组患者61例。研究结果显示:MSCT T分期与病理T分期Kappa值为0.706(P<0.05),MSCT T分期诊断准确率为79.00%;MSCT N分期与病理N分期Kappa值为0.718(P<0.05),MSCT N分期诊断准确率为83.00%;有效组CT肿瘤密度减低率、CT肿瘤体积减少率明显高于无效组(P<0.05);CT肿瘤密度减低率、CT肿瘤体积减少率预测化疗有效的ROC曲线下面积分别0.922和0.811(P<0.05)。胃癌分期应用MSCT有较好的诊断价值,且可预测化疗疗效。

Abstract: This study aimed to investigate the value of multi-slice spiral CT (MSCT) in staging diagnosis and chemotherapy efficacy prediction of gastric cancer. One hundred patients with gastric cancer treated were selected, all patients were treated with neoadjuvant chemotherapy and accepted MSCT examination. According to the efficacy of chemotherapy, 100 patients were divided into effective group with 39 cases and ineffective group with 61 patients. The results showed that, the Kappa value of MSCT T stage and pathological T stage was 0.706 (P<0.05), and the diagnostic accuracy rate of MSCT T stage was 79.00%. The Kappa value of MSCT N stage and pathological N stage was 0.718 (P<0.05), and the diagnostic accuracy rate of MSCT N stage was 83.00. The reduction rate of CT tumor density and CT tumor volume in the effective group were significantly higher than those in the ineffective group (P<0.05). In predicting the effectiveness of chemotherapy the area under ROC curve of CT tumor density reduction rate and CT tumor volume reduction rate were 0.922 and 0.811, respectively (P<0.05). MSCT has a good diagnostic value in preoperative staging of gastric cancer, and could predict the efficacy of chemotherapy.
