The curative effect of mammotome minimally invasive biopsy system in the treatment of benign breast mass / 中国基层医药

Objective To compare the curative effect of ultrasound guided mammotome minimally invasive biopsy system and open operation in the treatment of benign breast mass .Methods 60 benign breast mass patients with total 115 phymas were selected as treatment group , and were given the mammotome minimally invasive biopsy treatment .60 benign breast mass patients with total 105 phymas who were given traditional open operation at the same time,were selected as control group .The treatment effect and satisfaction condition of patients in the two groups were compared.Results The phymas of patients in two groups were all removed by operation .The operation time,blood loss,healing time and scar size after operation in the treatment group were all shorter than those in the control group (t=2.41,3.87,2.44,9.84,P<0.05 or P<0.01).The incidence rate of postoperative complication in the treatment group (6.66%) was significantly lower than that in the control group (20.00%)(χ2 =4.62,P<0.05).The postop-erative satisfaction of patients in the treatment group (95.00%) was significantly higher than that in the control group (20.00%)(χ2 =5.26,P<0.05).Conclusion Compared with open operation ,ultrasound guided mammotome min-imally invasive biopsy system in the treatment of benign breast mass has advantages of shorter operative time ,smaller operative trauma ,shorter postoperative healing time ,less operative complication ,higher satisfaction of patients .

Percutaneous Excision of a Benign Breast Mass Using Ultrasound-guided, Vacuum-assisted Core Biopsy: A Review of 197 Cases with Long Term Follow-up

PURPOSE: To assess long term results of excising benign masses using ultrasound (US)-guided, vacuum-assisted core biopsy (Mammotome). MATERIALS AND METHODS: We enrolled 163 patients (197 masses) receiving USguided excision using vacuum-assisted core biopsy and follow-up sonography in this retrospective study. The masses were category 3 as determined by ultrasound imaging according to the Breast Imaging Reporting and Data System (BI-RADS) (n=145) or pathologically confirmed as benign masses by a previous core-needle biopsy although category 4a and 4b (n = 52). Pathology, the presence of hematoma and residual tissue, as well as scar formation were assessed. RESULTS: We diagnosed 190 (96.5%) benign masses, 4 (2.0%) malignant masses, and 3 (1.5%) high-risk lesions. Most (176 masses, 91.2%) were excised completely as demonstrated by the follow-up ultrasound examination. Scar changes were minimal (68.7%) or moderate (31.3%), with regression in 53%. CONCLUSION: US-guided excision using vacuum-assisted core biopsy is effective for the removal of benign breast masses. The majority of scars are minimal, with good cosmetic effect. However, subsequent excision should be done for malignant masses or phyllodes tumor because radiologic absence does not guarantee complete removal.

Pathological Correlation of Re-excised Breast Lesions after the use of the Ultrasound-Guided Vacuum-Assisted Biopsy Device (Mammotome(R)) / 한국유방암학회지

PURPOSE: The Mammotome(R) biopsy is a relatively new surgical technique that is a minimally invasive image-guided procedure, requiring a small incision that produces a barely noticeable scar. The technique is a useful method for the surgical biopsy of properly selected patients. We reviewed the pathology of the biopsies for the proper selection of a mammotome biopsy in patients with re-excised breast tumors. METHODS: During a 24-month period, we performed vacuumassisted breast biopsies for 277 likely benign breast lesions using ultrasound and fine-needle aspiration cytology or a core needle biopsy, in 203 patients. The age of the patients ranged from 15 to 67 yr (average age 36.6 yr), and the average size of the lesions was 2.39+/-1.06 cm (minimum size 0.5 cm, maximum size 5.0 cm). We retrospectively analyzed the pathological findings of the re-excised breast lesions. RESULTS: The pathology of ultrasound-guided vacuum biopsies of the benign-appearing breast lesions were fibroadenomas (69.7%), intraductal papillomas (6.1%), fibrocystic disease (7.9%), phyllodes tumors (2.9%), malignant tumors (1.4%), ductal hyperplasia (2.9%), and other benign diseases (9.1%). Re-excision by a conventional method was performed for nine patients. Reasons for re-excision were the presence of five proven malignancies (a malignant phyllodes tumor in 2 cases, a tubular carcinoma in 1 case, a papillary carcinoma in 1 case and a ductal carcinoma in situ [DCIS] in 1 case), a possible atypical ductal hyperplasia (ADH) malignancy, two marginal involvement in phyllodes tumors and the possible extension of a lesion as an atypical papilloma. In the re-excised specimens, residual tissues were noticed in eight cases. An ADH lesion was proven as a DCIS. CONCLUSION: A case of suggested marginal involvements and/or a possible malignancy should be re-excised because of the high possibility of remnant lesions being present after the mammotome biopsy. The cytological and pathological review must be performed precisely before performing the mammotome procedures with considering of the clinical and radiological findings.

Clinical Analysis of Female Patients Under 20 Years of Age with Benign Breast Masses

BACKGROUND: Breast lesions in children and adolescents are rare and develop mainly in females. The management of breast masses in children and adolescents can be a perplexing problem for pediatricians and surgeons. It is well documented that breast lesions in females under 20 years of age rarely represent malignant disease. However, they frequently are a source of discomfort and anxiety for the patient, particularly when they do not resolve spontaneously. METHODS: To determine the frequency of different breast masses in females under 20 years of age on whom surgery was performed, we carried out a retrospective study of females under 20 years who were admitted to the Department. of Surgery of Soonchunhyang University Hospital for surgery between 1993 and 1995. RESULTS: The mean age was 17.9 years. A total of 44 surgical procedures were performed in 40 patients. The masses ranged in size from 0.8 cm through 7.0 cm. As to the location, the mass was in the right breast of 22 patients (50%) and in the left breast of 22 (50%). The most common location of the mass was in the right upper outer quadrant (13 patients, 29.5%). Of the 44 masses, fine-needle aspiration cytology was performed in 33 masses. Of them, 28 were fibroadenomas, 4 were fibrocystic disease, and 1 was a lipoma. Excisional biopsy was performed on 44 masses. Of them, 33 were fibroadenomas, 4 were fibrocystic disease, 5 was fibroadenoma and fibrocystic disease, 1 was a lipoma, and 1 was a lymphangioma. There were no malignancies. CONCLUSIONS: In female patients under 20 years of age, we suggest that benign breast should be studied for diagnosis, treatment, and histological feature.
