Neuro-specific enolase (NSE) immunostaining in breast cancer showed no major prognostic significance despite some correlations with estrogen receptor status and patient outcomes. Further research is needed for NSE

Area of Science:

  • Oncology
  • Biomarkers
  • Breast Cancer Research

Background:

  • Neuron-specific enolase (NSE) is a biomarker investigated for its role in various cancers.
  • Estrogen receptor (ER) status is a critical factor in breast cancer prognosis and treatment.

Purpose of the Study:

  • To evaluate the prognostic significance of NSE immunostaining in patients with breast carcinoma.
  • To explore the relationship between NSE positivity, ER status, and lymph node metastasis in breast cancer.

Main Methods:

  • Retrospective analysis of 98 breast carcinoma patients.
  • Modified radical mastectomy and axillary lymph node dissection.
  • Immunohistochemical staining for NSE and ER status determination.

Main Results:

  • NSE-positive tumors were more frequently ER-positive with higher ER values.
  • No difference in lymph node metastases at primary surgery between NSE-positive and negative groups.
  • NSE-positive tumors showed a trend towards more metastases post-surgery but a better outcome.

Conclusions:

  • NSE immunostaining did not demonstrate major prognostic significance in this 5-year follow-up study.
  • NSE positivity may correlate with ER status and influence patient outcomes, warranting further investigation.
