Summary
Our aim was to appreciate the value of our newly equipped ultrasonic device in assessing margin status and to evaluate the policy of oncoplastic surgery in breast-conserving treatment (BCT). Of 783 cases of primary breast cancer treated between January 1991 and December 2001, 407 cases undergoing BCT were studied. A GE-YMS Logiq 700 MR was introduced as the new device in January 2000 and its outcome was calculated. In BCT, we intended to take the policy of oncoplastic surgery with the goal of ultimately obtaining a negative margin using both image-guided biopsy and frozen section analysis. Ninety percent (366/407) of patients received radiation therapy. Outcome was calculated using crude rates of first site of failure. After introducing the new device, the rate of BCT increased to 80% (86/108) from 69% and the rate of pathologically negative margins (>5mm; PNM) also increased to 91% (78/86) from 82%. At a mean follow-up time of 49 months, the overall local recurrence rate was 0.5% (2/407). Comparatively high percentages of BCT and PNM were obtained mainly by introducing the Logiq 700 MR. A small local recurrence rate (0.5%) was derived from taking the policy of oncoplastic surgery.
