Summary

Sentinel node (SN) identification and biopsy using lymphoscintigraphy is a safe and effective technique for early breast cancer treatment. This study confirms the validity of the scintigraphic procedure in identifying sentinel nodes for biopsy.

Area of Science:

  • Oncology
  • Nuclear Medicine
  • Surgical Pathology

Background:

  • Early breast cancer management often involves axillary staging.
  • Sentinel node biopsy is a crucial technique for accurate staging.
  • Minimally invasive techniques are preferred for early-stage disease.

Purpose of the Study:

  • To evaluate the efficacy and safety of sentinel node (SN) identification and biopsy.
  • To assess the feasibility of lymphoscintigraphy in early breast cancer patients.
  • To validate the interdisciplinary approach in SN biopsy procedures.

Main Methods:

  • Lymphoscintigraphy performed 16-18 hours pre-surgery using 99mTc-Nanocoll.
  • Colloid administration via transdermal supralesional or ultrasound-guided intraparenchymal injection.

  • Gamma probe detection and histological evaluation (immunohistochemistry and standard histology) of identified nodes.

    • Main Results:

    • Scintigraphic visualization of SNs achieved in 49 out of 54 patients.
    • Single SN identified in 38 patients; multiple SNs in 11 patients.
    • No additional nodes detected on delayed scans; late migration observed with US-guided injections.

    Conclusions:

    • The scintigraphic procedure for SN identification is valid and safe.
    • The technique is feasible for early breast cancer treatment.
    • Successful interdisciplinary collaboration is essential for SN biopsy procedures.
