Objective: To analyze the relationship between the maximum intake of PETCT 18F-FDG and the clinical indicators of endometrial carcinoma.Methods: Sixty-four cases of endometrial cancer(EC) undergoing PET/CT in our hospital were selected as research subjects. PET, CT and PET/CT findings of lesion morphology and location were used to analyze relationship between the endometrial carcinoma maximum standard uptake value(SUVmax) and the clinical indicators,including tumor size, lymph node metastasis and pathological types. Results: The pathological diagnosis confirmed that there were 32 cases of lymph node metastasis in primary lesion, 20 cases of inguinal lesion and 12 cases of pelvic lesions. Comparison between the inguinal lesions and the pelvic lesions showed that the bigger the tumor was, the greater the SUVmax and SUVavg(P<0.05). The pathological diagnosis confirmed 21 cases of distant lymph node metastasis, 10 cases of lung metastasis and 11 cases of bone metastasis. The results showed that the bigger the tumor was, the greater the SUVmax, and that was also closely related to the metastatic lesions. The distant metastasis of lymph node type was positively correlated with tumor size, SUVmax and SUVavg results. Comparison of primary lesion size of different pathological types of EC with SUVmax and SUVavg showed no statistical difference(P>0.05).Conclusion: The primary tumor of endometrial carcinoma can be diagnosed by PET/CT 18F-FDG, which shows that the greater the value of SUVmax is, the bigger the tumor and that the more obvious the lymph node metastasis occurs. |
