Abstract:

Objective To investigate the value of ultrasound guided minimally invasive rotary mastectomy in screening breast cancer. Method A retrospective analysis was conducted on the clinical data of 238 patients who underwent breast rotational resection surgery at Changyang County Maternal and Child Health Hospital from October 2021 to June 2023. Summarize the proportion of patients undergoing ultrasound-guided minimally invasive rotational mastectomy. Result Among the 238 patients who underwent breast rotational resection surgery, 225 (94.54%) were diagnosed with benign lesions, including 146 cases (61.34%) of breast adenosis with adenoma formation (including breast adenosis), 68 cases (28.57%) of adenofi broma, 5 cases (2.10%) of intraductal

papilloma, and 6 cases (2.52%) of other benign lesions (active epithelial hyperplasia, with or without atypical hyperplasia); Nine cases (3.78%) were diagnosed with malignant lesions, including one case (0.42%) of ductal carcinoma in situ and eight cases (3.36%) of invasive ductal carcinoma; Two cases (0.84%) of borderline lobular tumors; 2 cases (0.84%) of precancerous lesions (atypical hyperplasia of ductal epithelium). 152 cases of BI-RADS type 3 nodules, 3 of which were diagnosed as breast cancer, with a malignant rate of 1.97%; There were 72 cases of BI-RADS 4a nodules, 6 of which were breast cancer, with a malignant rate of 8.33%; There were 14 cases of BI-RADS type 2 nodules, and no case of breast cancer was found. Conclusion Ultrasound guided minimally invasive rotary mastectomy has significant advantages as a biopsy method in the diagnosis of benign breast lesions and breast cancer due to its precise positioning, minimally invasive and safety, especially for those patients with BI-RADS classifi cation of grade 3 and 4a and high risk factors of breast cancer, especially those who are not suitable for regular observation.
