Interpectoral nodes may be the first site of breast cancer metastasis in some cases. This finding is crucial for accurate sentinel node biopsy results in breast cancer staging.

Area of Science:

  • Oncology
  • Surgical Pathology

Background:

  • Investigating the role of interpectoral lymph nodes in breast cancer metastasis.
  • Assessing the potential of interpectoral nodes as early indicators of cancer spread.

Purpose of the Study:

  • To determine if interpectoral nodes can function as sentinel nodes in specific breast cancer cases.
  • Evaluating the significance of interpectoral nodal involvement in breast cancer staging.

Main Methods:

  • Dissection of interpectoral nodes in 35 consecutive breast cancer patients undergoing axillary node dissection.
  • Separate pathological examination of interpectoral lymph node specimens.

Main Results:

  • Identified isolated metastasis in interpectoral nodes in three patients.

  • Demonstrated that interpectoral nodes can harbor metastatic breast cancer.

    • Conclusions:

    • Interpectoral nodes may represent the earliest site of nodal metastasis for upper quadrant or deep breast cancers.
    • Potential for false-negative results in sentinel node biopsies if interpectoral nodes are not considered.
    • Highlights the importance of considering interpectoral lymph nodes in breast cancer staging and surgical planning.
