Area of Science:

  • Oncology
  • Molecular Biology
  • Pathology

Background:

  • Prostate cancer diagnosis and treatment present global healthcare challenges.
  • Molecular research is crucial for advancing prostate cancer care.
  • High-quality fresh frozen human tissue is essential for this research.

Purpose of the Study:

  • To develop a standardized method for obtaining fresh frozen human prostate tissue.
  • To ensure the method does not compromise pathological diagnosis or staging.
  • To facilitate molecular studies using prostate cancer tissue.

Main Methods:

  • Radical prostatectomy specimens were processed using a novel rapid sampling technique.
  • Cylindrical tissue cores were snap-frozen in liquid nitrogen after marking on a prostate map.
  • Frozen sections were used for H&E staining and molecular analysis, ensuring pathology integrity.

Main Results:

  • The technique was applied to 150 prostates, with pathological assessment remaining uncompromised.
  • High cellularity was maintained in frozen tissues, allowing close monitoring.
  • High yields of quality RNA (mean 2.4 µg) and DNA (mean 12.7 ng) were extracted.

Conclusions:

  • This novel method provides rapid, high-quality fresh frozen prostate tissue for research.
  • The technique successfully preserves tissue integrity for both pathology and molecular studies.
  • It offers a reliable approach for molecular research in prostate cancer.
