the diagnostic efficacies of serum carbohydrate antigen 125 (CA125) and
18
F-fluorodeoxyglucose (
18
F-FDG) PET/CT were compared and their relationship was analyzed.
Methods:
18F-FDG PET/CT and serum CA125 assay were performed in 157 postoperative patient with ovarian cancer
and the time interval was less than 7 d.
Results:
PET/CT imaging detected 97 positive and 60 negative. The levels of CA125 were (188.61202.70) U/mL and (32.4967.61) U/mL in the positive group and negative group
respectively. There was significant difference (
P
0.001). According to International Federation of Gynecology and Obstetrics (FIGO) staging of ovarian cancer
16 werestage Ⅱ
33 stage Ⅲ and 48 stage Ⅳ. The levels of CA125 were (155.73174.23) U/mL
(181.01211.70) U/mL and (204.80207.48) U/mL
respectively. The corresponding SUV

values were 8.454.18
8.793.55 and 9.324.33. There was no significant difference in CA125 level and SUVmax value among three groups. There was a weak correlation between CA125 level and SUVmax value (
r
=0.203
P
=0.046). The receiver operating characteristic (ROC) curve analysis revealed that the optimal cut-off of CA125 level to predict positive
18
F-FDG PET/CT result was 19.07 U/mL
the area under curve (AUC) was 0.871 (0.810-0.931)
the sensitivity was 89.7%
the specificity was 81.7%
the positive predictive value was 86.1%
and the negative predictive value was 85.7%.
Conclusion:
Serum CA125 and PET/CT imaging in detecting the recurrence and metastasis of ovarian cancer have better consistency. Especially in the ovarian cancer patients with CA12519.07 U/mL
Association between the characteristics of conventional ultrasound combined with CEUS and the recurrence or metastasis of postoperative breast cancer
Value of combination of 18F-fluorodeoxyglucose PET/CT and serum carbohydrate antigen125 and human epididymis protein4 in diagnosis of recurrent or metastatic ovarian cancers
The value of multimodal imaging combined with CT, high-resolution MRI, and DWI in the diagnosis of postoperative anastomotic recurrence in rectal cancer
Value of deep learning ultrasound radiomics in predicting axillary lymph node metastasis of breast cancer
A case of invasive lobular carcinoma of the breast with multiple metastases underwent 68Ga-FAPI and 18F-FDG PET/CT imaging
