Natural history and clinical evaluation of the lumpectomy scar.
After lumpectomy with axillary dissection and radiation therapy, there are numerous changes that occur to the breast that, if unrecognized as routine, post-treatment changes, can lead to inappropriate intervention by the physician. The purpose of this study is to evaluate the time required to achieve stable post-treatment mammographic and physical findings. One hundred twenty-three patients age 56.6 years with a mean tumor size of 15.9 +/- 8.2 mm were observed every 6 months with a mean change in scar size of 16.7 +/- 10.6 mm. A scar never developed in 27 per cent and completely resolved or decreased in 90 per cent. Calcifications developed in 16 per cent of the patients; 40 per cent in the scar, 60 per cent outside the scar. Recurrence developed in 2 per cent of the patients at a mean time of 53 months and was believed to be favorably influenced by cytologic evaluation of the resection margins at the time of tumor excision. Stabilization or resolution of the post-treatment changes occurred within 24 to 36 months. The conclusion is for careful surgical and radiologic follow-up with examinations, fine-needle aspirations, and meticulous mammograms guiding the need for biopsy.
