Aim: To determine current practice in the UK of needle sampling of clinically and radiologically benign breast masses in young women.

A questionnaire regarding needle sampling practice in young women with clinically and radiologically benign breast masses was sent to 481 members of the Royal College of Radiologists Breast Group. This included questions on whether a written protocol is in place to allow avoidance of biopsy, and if so, the clinical and radiological criteria used.

Responses were available for analysis from 80 units. Forty-two (53%) units had no written policy in place, whilst 38 (47%) adhered to a written policy. Of those with a policy, an age criterion for safe avoidance of biopsy was present in 36 out of the 38 units (95%). The age limit used ranged from <25 years to <35 years. Twenty-seven (71%) written policies included clinical criteria but only four (10%) policies included a size criterion. Radiological criteria were present in all policies and the majority (74%) adhered to full Stavros criteria. Seven units (18%) used a revised form of the Stavros criteria and three units used their own criteria.
Conclusion

There is little concordance between symptomatic breast clinics regarding the criteria for avoidance of breast biopsy in this young patient group. Given the very low incidence of breast carcinoma in women less than 25 years old it is considered safe and feasible to adopt a standardized protocol across the UK and avoid the often-unnecessary benign biopsies in these patients

Nine women with breast cancer, seven with phyllodes, and six with papillomas were found.

No delayed diagnoses in those who had ultrasound would have been made if the following criteria had been applied to avoid needle sampling:

• age less than 25 years
• no known risk factors for breast malignancy
• mass not rapidly enlarging
• smooth discrete mobile mass on clinical examination, or lesion impalpable
• well-defined homogeneously isoechoic or mildly hypoechoic solid mass
• less than 3 cm in greatest dimension
• ovoid shape, aligned parallel to the skin surface
• smooth or gently lobulated contour (two or three lobulations only; no microlobulation
• thin echogenic pseudocapsule
• no calcification
• no acoustic shadowing

Needle sampling could have been safely avoided in approximately two-thirds of the women reviewed below the age of 25 with a solid breast mass

Aim - To evaluate the feasibility and safety of vacuum-assisted resection of benign breast tumours using an 8 G handheld device.

Materials and Methods - Over a 2-year period, 22 patients with 26 breast tumours diagnosed as benign using aspiration biopsy cytology were enrolled. The mean patient age was 38 years, and the mean maximal diameter of the tumour was 13 mm. A handheld Aloka SSD 6500 ultrasonography device with a linear-type 7.5 MHz transducer was inserted into the posterior aspect of the tumour with the patient under local anaesthesia, and the tumour was resected under ultrasonographic guidance.

Results - This method was employed successfully in all patients, and the mean operation time was 33 min. Post-procedure complications included subcutaneous bleeding in 12 cases and haematoma in one. The pathological diagnoses were fibroadenoma in 16 cases, mastopathy in six, and tubular adenoma and pseudoangiomatous stromal hyperplasia in two cases each, respectively. Follow-up ultrasonography revealed residual tumours in four cases (15.4%).

Conclusions - Although this method is feasible and safe without severe complications, it is necessary to select appropriate patients, and to obtain informed consent regarding the possibility of recurrence or residual tumour.
