Effect of primary polychemotherapy after sentinel lymph node biopsy on the necessity for lymphadenectomy in stage II breast cancer patients
2009
e11589 Background: Sentinel lymph node (SLN) biopsy is the standard procedure for assessing axillary status in stage I-II breast cancer patients. Realizing this procedure before the administration of primary polichemotherapy would reduce the number of unnecesary lymphadenectomy in patients with negative sentinel lymph node. Methods: From January 2006 to May 2008, twenty-one patients with breast cancer on stage II-IIIA were included in the study. The median age was of 49 years (range 22–74y). The median palpable tumour size was of 3.5cm (range 1.8–6.0) and by ultrasonography 2.0cm (range 1.8–5.0cm.). Stage II:19 and Stage III:2 (cT:6.0cm.). Breast biopsy was performed in all cases with: IDC:20. G1:9 (42,8%), G:2:11(52%) and G3:1(4,76%). ER+:18 (85,7%), PR+:13 (61,9%), HER2 (+):6 (28,5) and triple negative:3 (14,2%).The scheme of treatment was: 4Epi: 90mg/M2 and Cyclophosphamide 600mg/M2 day 1/3w/4cycles, followed by paclitaxel (P) 100mg/M2 day 1/wekly/8. Trastuzumab was given during one year 4/2mg/Kg and s...
