Neck dissections may involve the carotid sheath, but cancer cells were not found within it. Lymphoid aggregates in the carotid sheath suggest a role in neck cancer recurrence after surgery.

Area of Science:

  • Oncology
  • Surgical Pathology

Background:

  • Neck recurrences after neck dissection can occur in previously operated areas.
  • The pathogenesis of these recurrences is not fully understood, but often involves the jugular chain near the carotid artery.

Purpose of the Study:

  • To investigate the carotid sheath as a potential site for regional recurrences following neck dissection.

Main Methods:

  • Prospective enrollment of patients undergoing therapeutic or elective neck dissections.
  • Resection and histological examination of the entire carotid sheath post-surgery.

Main Results:

  • Histological analysis of 40 carotid sheaths revealed fibro-fatty tissue and minimal inflammation in all specimens.
  • Four lymphoid aggregates, primarily B cells, were identified at the carotid bifurcation in three patients.

  • No cancer cells were detected within the carotid sheaths.

    • Conclusions:

    • The absence of cancer cells in the carotid sheath suggests it is not necessary to resect routinely during neck dissection.
    • The presence of lymphoid aggregates may implicate the carotid sheath in the pathogenesis of nodal recurrence after neck dissection.
