Sentinel node biopsy is feasible for breast cancer staging, with a combined dye and gamma probe method improving accuracy. However, it

Area of Science:

  • Oncology
  • Surgical Pathology
  • Medical Imaging

Background:

  • Accurate staging of breast cancer is crucial for effective treatment planning.
  • Sentinel lymph node biopsy (SLNB) is a minimally invasive technique to assess axillary lymph node involvement.
  • Evaluating the technical feasibility and predictive capacity of SLNB is essential for its clinical adoption.

Purpose of the Study:

  • To assess the technical feasibility of sentinel node biopsy in breast cancer patients.
  • To determine the accuracy of sentinel node biopsy in predicting axillary lymph node status.
  • To evaluate the utility of combined patent blue dye and lymphoscintigraphy for sentinel node identification.

Main Methods:

  • A prospective study involving 70 patients with invasive breast carcinomas.

  • Lymphatic mapping using patent blue dye and lymphoscintigraphy with a gamma probe.
  • Sentinel node biopsy followed by axillary clearance (Berg's level 1 and 2).

    • Main Results:

    • Sentinel node identification was successful in 94.26% of patients.
    • The sentinel lymph node was involved in 32.8% of cases, and was the only positive node in 14.2%.
    • Two false-negative sentinel lymph node results were observed.

    Conclusions:

    • Sentinel node mapping is technically feasible, with combined methods enhancing detection.
    • A learning curve is associated with mastering the sentinel node biopsy procedure.
    • SLNB is not recommended for tumors >3 cm due to increased risk of nodal involvement and need for axillary clearance.
