Repeat sentinel lymph node (SLN) biopsy may be feasible for staging breast cancer patients with in-breast recurrences. This case shows a positive SLN biopsy result in a patient with recurrent breast cancer after initial negative results and radiation therapy.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Breast Cancer Research

Background:

  • Sentinel lymph node (SLN) biopsy is a standard staging procedure for breast cancer.
  • In-breast recurrences and new primary breast cancers can occur after initial treatment.
  • Re-evaluation of the lymphatic basin may be necessary in such cases.

Observation:

  • This report details a patient with breast cancer experiencing an ipsilateral recurrence.
  • The patient had previously undergone lumpectomy, radiation therapy, and a sentinel lymph node biopsy with negative results.
  • Fourteen months later, a new primary breast cancer was diagnosed, and a repeat SLN biopsy was performed.

Findings:

  • The repeat sentinel lymph node biopsy in this patient with recurrent breast cancer yielded a positive result.

  • This contrasts with the initial negative SLN biopsy outcome.
  • The findings suggest the potential for detecting metastatic disease in the lymph nodes during recurrence.

    • Implications:

    • Repeat sentinel lymph node biopsy could be a viable option for staging recurrent breast cancer.
    • This technique may help guide further treatment decisions in patients with in-breast tumor recurrence.
    • Further research is warranted to establish the safety and efficacy of repeat SLN biopsy in diverse clinical scenarios.
