The Value of PET-CT Combined with B-ultrasound in Axillary Lymph Node Metastasis of Breast Cancer
Objective To analyze the diagnostic effect of positron emission tomography-computed tomography(PET-CT)combined with B-ultrasound in axillary lymph node metastasis of breast cancer.Methods The medical records of 60 breast cancer patients admitted to Tianjin Baodi District People's Hospital from April 2021 to December 2023 were retrospectively analyzed.All patients received B-ultrasound and PET-CT examination.The results of pathological examination were used as the gold standard.The diagnostic performances of B-ultrasound,PET-CT and combined examination were compared for axillary lymph node metastasis of breast cancer.Results In 60 cases of breast cancer,pathological examination showed that axillary lymph node metastasis was positive in 49 cases and negative in 11 cases of breast cancer.B-ultrasound showed that there were 42 positive and 18 negative cases of axillary lymph node metastasis in breast cancer.PET-CT showed that there were 44 positive and 16 negative cases of axillary lymph node metastasis in breast cancer.PET-CT combined with B-ultrasound showed that 47 cases of breast cancer had axillary lymph node metastasis and 13 cases were negative.The sensitivity,accuracy and negative predictive value of PET-CT combined with ultrasound were all significantly higher than those of B-ultrasound and PET-CT alone(P<0.05).There was no significant difference between B-ultrasound and PET-CT in the diagnosis of axillary lymph node metastasis of breast cancer(P>0.05).Conclusion PET-CT combined with B ultrasound has a better effect in the diagnosis of axillary lymph node metastasis of breast cancer,which is superior to B ultrasound and PET-CT alone.
