Frozen section (FS) analysis of 244 specimens showed high accuracy for surgical margins and lymph node metastasis detection. FS is most beneficial for diagnosing unknown pathologic processes, achieving 98.2% accuracy.

Area of Science:

  • Oncology
  • Pathology
  • Surgical Pathology

Background:

  • Frozen section (FS) is a rapid diagnostic technique used in surgical pathology.
  • Its accuracy and utility in various clinical scenarios require ongoing evaluation.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of frozen section (FS) examinations.
  • To determine the optimal application of FS in oncologic diagnostics.

Main Methods:

  • Retrospective analysis of 244 frozen section (FS) specimens examined between 1987 and 1988.
  • Categorization of FS use into surgical margin evaluation, lymph node metastasis detection, and diagnosis of unknown pathologic processes.

Main Results:

  • FS demonstrated 100% accuracy for surgical margin and lymph node evaluations (65 cases).

  • For diagnosing unknown pathologic processes (179 cases), overall accuracy reached 98.2% when combining precise and correct diagnoses.
  • Diagnostic deferral occurred in 11.17% and incorrect diagnoses in 2.24% of unknown process cases.

    • Conclusions:

    • Frozen section (FS) is highly accurate for evaluating surgical margins and lymph node metastasis.
    • FS provides significant diagnostic value for unknown pathologic processes, with an overall accuracy of 98.2%.
    • The utility of FS is greater in general diagnosis of unknown conditions than for precise diagnoses.
