RESUMO
Objective:To analyze the diagnostic value of sex hormone combined with carcinoembryonic antigen on lymph node metastasis in breast cancer patients.Methods:52 cases of breast cancer patients who underwent surgical resection were collected and divided into non-metastasis group and metastases group after axillary lymph node ultrasonography. The blood samples was collected from patients and the levels of serum estradiol, testosterone, progesterone and carcinoembryonic antigen were detected; The diagnostic value of the above indexes in patients with lymph node metastasis was analyzed; Logistic risk regression model was used to analyze the independent risk factors for lymph node metastasis after surgical resection.Results:There were significant differences between the non-metastatic group and the metastatic group in the largest tumor diameter and menopause (all P<0.05), but there were no significant differences among other general data (all P>0.05). The serum estradiol level in the non-metastatic group was (153.97±35.55) pg/ml, the progesterone level was (0.33±0.05) ng/ml, and the carcinoembryonic antigen level was (11.44±3.77) ng/ml, while the estradiol level in the metastatic group was (207.19±52.11) pg/ml ( t=4.13, P<0.001), progesterone level (0.38±0.04) ng/ml ( t=4.01, P<0.001), carcinoembryonic antigen level (15.41±3.46) ng/ml ( t=3.94, P<0.001). The above three indicators were significantly increased in patients in the transfer group. The area under the curve of estradiol was 0.83, the area under the curve of progesterone was 0.80, the area under the curve of carcinoembryonic antigen was 0.77, the area under the curve of the combination of the three was 0.85, and the area under the curve of the combination of the three was the largest. Logistic risk regression model showed that estradiol, progesterone, and carcinoembryonic antigen levels were independent risk factors affecting lymph node metastasis in breast cancer patients (all P<0.05) . Conclusion:The sex hormone estradiol, progesterone combined with carcinoembryonic antigen has a high diagnostic value for lymph node metastasis in patients with breast cancer, and can independently predict the occurrence of lymph node metastasis in breast cancer patients.
