Summary
Prostate cancer screening using prostate-specific antigen (PSA) has increased early detection but also overdiagnosis. Improving prostate needle biopsy techniques and incorporating molecular findings are crucial for better active surveillance protocols.
Area of Science:
- Urology
- Oncology
- Pathology
Background:
- Prostate cancer (PCa) is a common cancer in older men, with increasing detection rates due to prostate-specific antigen (PSA) screening.
- Widespread PSA screening has led to a rise in localized PCa detection and a decrease in PCa mortality.
- However, PSA screening is associated with up to 50% overdiagnosis, leading to unnecessary treatments and unclear overall benefits.
Purpose of the Study:
- To review current prostate needle biopsy practices.
- To identify areas for improvement in prostate biopsy techniques.
- To discuss the role of quantitative histology and molecular findings in active surveillance for prostate cancer.
Main Methods:
- Review of established prostate needle biopsy techniques (sextant, extended 12-18 cores, saturation).
- Discussion of different biopsy modalities: transrectal, transperineal, and targeted biopsy.
- Emphasis on quantitative histology and novel molecular findings in pathology.
Main Results:
- Extended biopsy protocols and quantitative histology are becoming standard in pathology.
- There is a need to evaluate the clinical implications of various biopsy modalities.
- New molecular findings are increasingly important alongside conventional histology.
Conclusions:
- Current prostate biopsy protocols may lead to the detection of indolent tumors.
- Optimizing prostate needle biopsy methods is essential for accurate diagnosis and treatment decisions.
- Integrating quantitative histology and molecular markers will enhance active surveillance strategies for prostate cancer.
