摘要
探讨了18F-FDGPET/CT对结直肠癌术前TNM分期的价值。41例结直肠癌患者均于手术治疗前两个星期内进行PET/CT检查,将PET/CT结果与手术病理学检查结果对结直肠癌原发灶的诊断对比分析,发现18F-FDGPET灵敏度为97.6%,PET/CT为100%。18F-FDGPET/CT对结直肠癌术前T分期、术前N分期、远处转移及TNM分期的准确性分别为85.4%、85.4%、97.6%和75.6%,均与手术病理学检查结果一致(0.574,0.670,0.918,0.664,均P<0.001)。得出结论:直肠癌18F-FDGPET/CT检查结果与手术病理学检查结果有较好的一致性,可用于结直肠癌的术前临床分期。
In this paper we discuss the value of ^18F-FDG PET/CT on the TNM staging of colorectal cancer before surgery. Forty-one patients diagnosed with colorectal cancer from surgery were examined by ^18F-FDG PET/CT. PET/CT findings were compared with post-operative pathology. The sensitivity of colorectal cancer was 97.6% by PET and 100% by PET/CT. The diagnostic accuracy of T-stage and N-stage and metastasis and TNM-stage before operation in colorectal cancer were 85.4%, 85.4%, 97.6% and 75.6% respectively, and the correlation with surgical appearances and pathological findings were 0.574, 0.670, 0.918 and 0.664 respectively, all P〈0.01. Good correlation exists between manifestations on PET/CT and operative pathology. PET/CT may become a good choice diagnostic modality for pre-treatment staging evaluations of colorectal carcinomas.
