To compare ROLL technique vs standard wire guide method in excision of non palpable breast cancer lesions.

200 patients (p) (cT1N0) out of 843 p with occult breast cancer operated on conservative breast surgery and sentinel node biopsy during the period from June 2000 to december 2008 were retrospectively analysed. Two groups of patients were analyzed depending on the method that had been used to localized the occult lesion. Group A (ROLL method): 100p. Group B (wire guide method): 100p. The following factors were analysed: total tumor excision, maximun diameter of excised tissue and the number of patients who needed re-excision of involved margins in the same operation because of positive intraoperative anatomopathological exam. Delayed histopathology was classified as: involved margins (<2mm), next margins (2-10 mm) and clear margins (>10mm) of invasive carcinoma. The number of patients who need second therapeutic operation because of persistence of involved margins in the delayed anatomopathological exam was also analysed. Statistical analysis: chi-square method was performed and it was considered significative at p < 0,05.  

All tumors were successfully localised and excised with ROLL and WGL method. The mean maximun diameter of tissue excised was 6,31 cm in group A and 6,73 cm in group B. There were no significant differences (p < 0,05) in re-excision of involved margins in the same operation (49p group A and 44p group B). Clear margins were significantly (p<0,05) lower in group A (92p) than in group B (99p). Next margins were diagnosed in 8p in group A and 0p in group B. Involved margin who needed a second therapeutic operation occured only in 1p from group B   

ROLL method is as effective as wire guide method for excision of non palpable breast lesion without involved margins of invasive carcinoma and without increase surgical length. ROLL technique is easier, quicker and simplier than WGL method, not only for patients but also for surgeons, radiologists and pathologists

ROLL method improves conservative breast cancer surgery
