We completely agree that a hemipelvis approach to biopsy of sentinel lymph nodes (SLNs) for uterine cervix cancer can be very perspective and effective. The efficacy of this algorithm was proposed at the beginning of the century [1], and the recommendation to perform a complete lymphadenectomy in any hemipelvis that does not mapped is widely accepted in clinical practice. Our personal data are mostly in agreement with this approach: 3 women with unilateral localization of SLNs had metastases in hemipelvis that were not mapped and the last patient had bilateral metastases in non-SLNs. At the same time, we must also consider another point of view when “the pelvic basin is regarded as a unit” [2]. According to this approach, accuracy and safety of SLN biopsy are sufficiently higher in women with small (
