Area of Science:

  • Oncology
  • Pathology
  • Molecular Biology

Background:

  • Temporal bone squamous cell carcinoma (TBSCC) is aggressive with high recurrence rates.
  • Achieving oncologically safe surgical margins in bone is challenging.
  • Relaxin-2's potential role in tumor-driven osteolysis warrants investigation.

Purpose of the Study:

  • To evaluate the prognostic significance of relaxin-2 expression in TBSCC.
  • To assess relaxin-2 expression in tumor tissue and negative bone margins.
  • To determine if relaxin-2 correlates with recurrence, disease-free survival (DFS), or disease-specific survival (DSS).

Main Methods:

  • Immunohistochemistry was used to assess relaxin-2 expression.
  • 25 consecutively operated TBSCC patients' specimens were analyzed.
  • Correlation with pathological variables, recurrence, DFS, and DSS was examined.

Main Results:

  • Several pathological variables (pT stage, pN status, grade, dura mater involvement) correlated with recurrence, DFS, and DSS.
  • Relaxin-2 expression in TBSCC or negative bone margins did not correlate with recurrence rate, DFS, or DSS.
  • This preliminary study suggests relaxin-2 does not mediate local aggressiveness in TBSCC.

Conclusions:

  • While other factors influence TBSCC recurrence, relaxin-2 expression does not appear to be a prognostic indicator.
  • Further research into the molecular mechanisms of TBSCC recurrence is needed.
  • The role of relaxin-2 in TBSCC aggressiveness requires additional investigation.
