Description
Background It is very important to excise ductal carcinoma in situ (DCIS) with sufficient margins to prevent local recurrence. We describe the experience of ultrasonography (US)-guided and/or mammography (MMG)-guided breast conserving surgery (BCS) for DCIS. Methods In this retrospective study, we considered 87 consecutive lesions of 86 patients treated with US- and/or MMG-guided BCS between January and December 2006. Results The mean age of the 86 patients was 50.0 years (range 28–80 years). Preoperative mapping was performed using US alone for 49 lesions without microcalcifications and using US and MMG for 38 lesions with microcalcifications. Eighty-one (93.1%) of the 87 lesions were diagnosed as non-comedo type or mixed type, and 6 lesions (6.9%) were diagnosed as comedo type of DCIS. Sixty-five lesions (74.8%) were diagnosed as negative margins, 15 lesions (17.2%) as close margins, and 7 lesions (8.0%) as positive margins. Three lesions (3.4%) without microcalcifications that were mapped using US alone underwent additional resection in a second operation. The maximum tumor size was correlated with margin status (p = 0.043). Conclusion Thus US- and/or MMG-guided BCS is a reliable method for treating patients with DCIS regardless of histopathological type and offers the advantage of being noninvasive and nonstressful for patients
