| 目的 比较直肠癌腔内超声(TRUS)分期与CT分期的诊断价值并探讨TRUS、血清癌胚抗原(CEA)、CT联合应用对直肠癌分期的诊断价值。方法 对经病理证实的85例直肠癌患者术前行TRUS及CT检查并对肿瘤进行分期,同时检测术前血清CEA水平。结果 以术后病理结果为标准,直肠癌术前TRUS和CT分期诊断准确率差异无统计学意义(P＞0.05)。血清CEA水平随病理分期的增加而增高。术前单独应用TRUS分期的诊断准确率为80.00%。TRUS联合血清CEA检测直肠癌术前分期诊断准确率达88.24%,而三种方法联合应用可使分期诊断准确率达96.47%。结论 术前TRUS分期对于早期直肠癌的诊断优于CT。联合应用TRUS、血清CEA检测及CT可提高直肠癌术前分期诊断准确率。 |

| Objective To compare the efficiency of transrectal ultrasonography (TRUS) and CT in preoperative staging of rectal carcinoma, and to explore the diagnostic value of the combination of TRUS, serum carcinoembryonic antigen (CEA) detection and CT. Methods Eighty-five patients with rectal carcinoma confirmed pathologically underwent TRUS and CT scan before surgery operation. Serum CEA level was measured before operation. Results Taking pathological results as the standard, there was no significant difference between TRUS and CT of diagnostic accuracy rate in staging of rectal carcinoma (P＞0.05). Serum CEA level increased gradually with the pathological stage. The diagnostic accuracy rate of tumor staging was 80.00% with TRUS and was 88.24% with TRUS combined with serum CEA detection, and was 96.47% when using the above three methods. Conclusion The diagnostic value of TRUS in preoperative staging of rectal carcinoma is superior to that of CT in identifying early lesions. Combination of TRUS, serum CEA detection and CT can improve diagnostic accuracy rate in preoperative staging of rectal cancer. |
