Abstract

Aim: Most breast surgeons generally assume that obtaining negative margins in nonpalpable tumors is a matter of concern. The aim of this study was to examine whether it is easier to obtain negative margins in palpable tumors than in nonpalpable tumors excised with the radioguided occult lesion localization (ROLL) technique. Methods: A retrospective review was made of nonpalpable breast cancers excised with the ROLL technique (ROLL group, n = 83) and palpable breast cancers in which breast conservative therapy was performed (Palpable group, n = 77). The margin status and the size of the minimum margin obtained when it was negative were reviewed. Results: The percentage of resections with negative margins was similar in both groups: 51.9% in the Palpable group and 61.4% in the ROLL group. There was no difference between the two groups in the minimum margin obtained: mean ± SD, 5.53 ± 3.146 mm in the Palpable group and 5.96 ± 3.039 mm in the ROLL group. Risk factors for failing to obtain negative margins were analyzed in both groups and were similar. These risk factors included histological grade, extensive intraductal carcinoma and c-erbB2 status. Conclusion: It is concluded that excision of nonpalpable breast tumors with the ROLL approach obtains similar results for margins as conservative surgery performed for palpable tumors. © 2011 Japan Society of Obstetrics and Gynecology.
