Back­ground. The sur­gical man­age­ment of non-pal­pable ­breast ­lesions ­remains con­tro­ver­sial. At our Insti­tute we ­have intro­duced a new tech­nique, radio­guided ­occult ­lesion local­isa­tion (­ROLL) to ­replace stan­dard ­methods and over­come ­their dis­ad­van­tages. In ­this ­paper tech­nical ­aspects of ­ROLL and ­results on a ­large ­series of ­patients are ­reported.
­Methods. We ana­lysed 812 con­sec­u­tive ­patients ­with 816 non-pal­pable ­breast ­lesions ­detected mam­mo­graph­i­cally or ultra­son­i­cally. 99mTc-­labelled par­ti­cles of ­human ­serum ­albumin (7-10 MBq) in 0.2 ml ­saline ­were ­injected ­into the ­lesion ­under ster­eo­tactic mam­mo­graphic or ultra­sonic guid­ance. Mam­mog­raphy and scin­tig­raphy ­were ­then per­formed. ­With ultra­sound guid­ance ­only scin­ti­graphic con­trol was nec­es­sary. The exci­sion ­biopsy was car­ried out ­with the aid of a ­hand-­held γ-­detecting ­probe, and ­entire ­removal of the ­lesion was ver­i­fied by X-ray of the spec­imen.
­Results. The ­tracer was cor­rectly posi­tioned ­initially in 772/816 (94.6%) ­cases and at ­second ­attempt in ­another 2. In 42/816 (5.1%) ­cases, ­lesion local­isa­tion had to be ­repeated ­using a tra­di­tional ­approach. X-ray dem­on­strated the ­lesion was ­entirely ­removed in 770/774 (99.5%) ­cases. Path­o­log­ical exam­ina­tion ­revealed 367 (47.4%) ­benign ­lesions and 407 (52.6%) can­cers. The can­cers ­were ­treated by con­ser­va­tive ­breast sur­gery in 99.5% of ­cases.
Con­clu­sions. We con­cluded ­that ­ROLL ­enables the sur­geon to ­remove ­occult ­breast ­lesions ­easily and reli­ably.
