PURPOSE: To examine factors associated with one step surgery in case of non-palpable breast cancer. MATERIALS AND METHODS: Clinical data of 152 consecutively diagnosed patients with breast cancer were analyzed retrospectively. Preoperative diagnostic findings were divided in subgroups: mammographically visible mass/microcalcifications/sonographically visible mass/sonographically visible architectural distortion. Correlation between tumor-size, radiologic tumor morphology, quality of localization and number of operation was evulated. For localization exact wire position was defined less than 3mm apart from the lesion. RESULTS: One hundred and thirty-six patients attempted breast conservation and underwent preoperative tumor localization. Fourteen of 16 patients had mastectomy without preoperative localization. Average tumor size was 12mm for one-operation, and 17mm for re-operation. Significant correlation (p<0.001) was found between one operation and masses visible in mammograms (55/62 (89%) patients) or sonography (53/64 (83%) patients). Significant correlation was found (p<0.001) between more re-operation and microcalcifications in mammograms (33/89 (37% patients). In 123/138 (89%) cases wire position was central, in 15/138 (11%) cases distance was maximally 10mm. No significant correlation was found between number of operation and wire position. Re-operation was required in 38 cases. CONCLUSION: Mammographically or sonographically visible mass, small size of tumors, preoperative percutaneous biopsy and exact preoperative localization are important for a single step procedure for definite surgical treatment, that we found in 74% of the patients.
