[Optimization of the extent of surgery in organ- preserving treatment for invasive cervical cancer (the role of sentinel lymph nodes study)].

The study included 44 patients with Stage Ia₁ - lb₁ cervi- cal cancer who underwent organ-preserving surgery (transab- dominal trachelectomy). To visualize sentinel lymph nodes - lymphoscintigraphy with injection of radioactive lymphotropic isotope - (99m)Tc-labelled nanocolloid was injected a day before surgery. Intraoperative identification of sentinel lymph nodes using gamma probe was carried out to assess, which lymph nodes had taken up the radionuclide.
