Summary

Cytology identified high-grade prostatic adenocarcinoma in five patients with urinary symptoms. Prostatic-specific antigen (PSA) positivity and large nucleoli were key diagnostic indicators.

Area of Science:

  • Uropathology
  • Cytopathology
  • Oncology

Background:

  • Prostatic adenocarcinoma diagnosis relies on histopathology and biomarker analysis.
  • Cytologic examination of urinary tract specimens can aid in diagnosing prostate cancer.
  • Prostatic-specific antigen (PSA) is a crucial biomarker for prostate cancer detection.

Purpose of the Study:

  • To evaluate the cytologic findings in patients with high-grade prostatic adenocarcinoma.
  • To identify key cytologic features indicative of prostatic origin and malignancy.
  • To assess the utility of prostatic-specific antigen (PSA) in cytologic preparations.

Main Methods:

  • Retrospective review of cytologic preparations from five patients.
  • Analysis of cell morphology, including nucleoli characteristics.

  • Immunohistochemical staining for prostatic-specific antigen (PSA).

    • Main Results:

    • Four patients diagnosed with prostatic adenocarcinoma; three showed PSA-positive malignant cells.
    • A fifth patient had PSA-positive cells suggestive of prostatic origin without overt malignancy.
    • All five patients presented with high-grade prostatic adenocarcinoma (Gleason's Grade 8-10) and urinary symptoms.
    • Large and multiple nucleoli were identified as significant cytologic features for prostatic origin.

    Conclusions:

    • Cytologic examination, combined with PSA staining, can be valuable in diagnosing prostatic adenocarcinoma.
    • Specific cellular morphology, particularly nucleoli features, aids in identifying prostatic origin.
    • Early detection of high-grade prostate cancer is crucial for patient management.
