Application value of digital tungsten-molybdenum dual target three-dimensional positioning indwelling guide wire excision biopsy in diagnosis of breast microcalcification

Abstract

OBJECTIVE: To explore the application value of digital tungsten-molybdenum double target three-dimensional positioning indwelling guide wire and guided surgical resection biopsy in the diagnosis of breast microcalcification. METHODS: A retrospective analysis of 168 patients with negative clinical palpation and molybdenum target X-ray examination found breast abnormalities were equally divided into two groups according to different surgical positioning methods. The control and observation group underwent gross positioning biopsy and digital tungsten-molybdenum dual-target three-dimensional positioning indwelling guide wire to guide surgical resection biopsy, respectively. The results of molybdenum target X-ray examination and the success rate of one-time complete resection of the lesions were compared between the two groups, and the corresponding relationship between the pathological diagnosis results of the lesions after surgical resection and the performance of mammography in the observation group was compared. RESULTS: There was no significant difference in age and molybdenum target X-ray examination results between the two groups (P > 0.05). General information is comparable; the success rate of one-time complete resection of lesions in the observation group was significantly higher than that in the control group (95.2% vs 78.6%, P = 0.024). There were 34 cases of malignant lesions in the observation group, accounting for 40.5% (34/84), including 11 cases of invasive ductal carcinoma (64.7%), 50 cases of benign lesions, accounting for 59.5% (50/84), including 16 cases of breast lobular hyperplasia (32%), 18 cases of breast cystic hyperplasia (36%). CONCLUSION: In diagnosis of breast microcalcifications, surgical resection biopsy guided using digital tungsten-molybdenum double target three-dimensional positioning indwelling guide wire achieves high success rate and has advantages of high safety and accurate diagnosis. Thus, it has potential to play a greater role in early diagnosis of breast cancer and is worthy of clinical application.
