INTRODUCTION: @entity1600 ( @entity1600 ) biopsy, primary used as an alternative to elective lymph node dissection in @entity320 , is being applied successfully in management of @entity1 with @entity0 . The aim of this method in @entity0 is to determine the presence of axillary node involvement while clinically normal axilla. The validity of the sentinel node concept in @entity0 is demonstrated in various studies. The results of identification rates, sensitivity, overall accuracy and false negative rate are so encouraging in most publications, as to implement this concept to every-day surgical practice. There is lack, however, of many fundamental answers pertaining relationship between @entity5 -size and the results of @entity1600 Biopsy or related surgical standards. MATERIALS AND METHODS: 36 females at the age 33-66, with @entity0 underwent primary surgical treatment with @entity1600 Biopsy in Department of Gynaecology and Oncology Jagiellonian University between 2001-2002. The study inclusion criteria were @entity5 size-T1, T2. The day before surgery the static scanning was performed after injection of Tc radiolabelled nannocolloid. @entity1600 (s) were identified intraoperatively using a handheld gamma detection probe (Navigator GPS) and intraoperative lymphatic mapping with blue dye (Patent @entity6820 V). After localization and excision of @entity1600 (s), axillary's lymph node dissection (ALND) was performed. RESULTS: In 34 @entity1 @entity1600 Biopsy revealed accumulation of the tracer in axilla, which was classified as @entity1600 . Detection rate was 94.4% (34/36). Overall sensitivity of the procedure was 81%, whereas negative predictive value 92%. False negative rate was 2.2%. Detection rate for T1 @entity5 was 100% (15/15 cases), and for T2 @entity5 was 90.4% (19/21 cases). Sensitivity for @entity5 classified as T1 was 100% (3/3 cases), whereas for @entity5 T2 was 75% (6/8 cases). CONCLUSION: @entity1600 Biopsy seems to be very interesting alternative to ALND in @entity1 with @entity5 's dimension.
