Summary

The combination of blue dye and radioguided techniques for sentinel lymph node biopsy (SLNB) offers superior accuracy in breast cancer staging compared to blue dye alone. This method improves detection rates and reduces false negatives in axillary lymph node assessment.

Area of Science:

  • Oncology
  • Surgical Pathology

Context:

  • Axillary lymph node status is critical for breast cancer prognosis.
  • Sentinel lymph node biopsy (SLNB) is preferred over complete axillary lymph node dissection (CALND) for staging due to its accuracy and reduced complications.

Purpose:

  • To compare the accuracy of blue dye technique versus a combination of blue dye and radioguided technique for sentinel lymph node detection.
  • To evaluate the effectiveness of a two-day protocol for Tc 99 radiocolloid application in SLNB.

Summary:

  • A study compared 21 SLNBs using blue dye (Group A) with 20 SLNBs using combined blue dye and radioguided techniques (Group B).
  • Sentinel lymph nodes were missed in two cases and had two false negatives in Group A.
  • Sentinel lymph nodes were detected in all cases in Group B, with no false negatives.

Impact:

  • The combined blue dye and radioguided technique is more accurate for sentinel lymph node detection than the blue dye technique alone.
  • The two-day Tc 99 radiocolloid protocol facilitates SLNB even in facilities lacking a Nuclear Medicine Department, enhancing accessibility.
