摘要
目的评价FDGPET对结直肠癌术后复发及转移的价值。方法51例结直肠癌术后患者行FDGPET显像,并与CT及血清CEA结果进行比较。结果FDGPET诊断结直肠癌术后复发的灵敏度、特异性、准确性分别为94.3%、93.8%、94.1%;CT结果为84.4%、57.9%、74.5%;血清CEA结果为57.9%、85.7%、65.4%。51例患者中FDGPET显像发现29例肝脏转移,灵敏度为100%,CT诊断肝转移21例,灵敏度为72.4%。结论FDGPET显像评价结直肠癌术后复发与转移明显优于CT及血清CEA。
Objective To evaluate the value of FDG PET in recurrence and metastasis of colorectum cancer post-operation. Methods FDG PET imaging were performed for 51 post-operation colorectum cancer patients, and compared with CT scans and serum tumor marker CEA. Results The sensitivity, specificity and accuracy of FDG PET were 94.3%, 93.8% and 94.1 %, for CT were 84.4 %, 57.9 %, 74.5 %, and for CEA were .57.9 %, 85.7 %, 65.4 % respectively. PET also found 29 liver metastasis, CT found 21 metastasis, the sensitivity of PET and CT were 100% and 72.4% respectively. Conclusion FDG PET is superior to CT and CEA in diagnosis of recurrent and metastasis colorectum cancer post-operation.
