Summary
Echocolour and power Doppler show varied vascular patterns in prostate cancer, but no single pattern reliably aids diagnosis or biopsy guidance. Further research is needed to clarify their role in prostate neoplasia.
Area of Science:
- Urology
- Medical Imaging
- Oncology
Background:
- The diagnostic utility of echocolour and power Doppler for prostate carcinoma remains unclear.
- Lack of consensus impacts decisions regarding prostate cancer diagnosis and biopsy guidance.
Purpose of the Study:
- To assess the echocolour and power Doppler patterns in patients diagnosed with prostate carcinoma.
Main Methods:
- Seventy patients with suspected prostate neoplasia and hypoechoic areas on transrectal ultrasound underwent evaluation.
- Ultrasound-guided biopsies confirmed adenocarcinoma with Gleason scores ranging from 3 to 10.
Main Results:
- Perilesional vascularization was observed in 57.14% of cases, with limited intralesional signals.
- Hypervascularization within neoplastic areas occurred in 21.4% of cases.
- Hypovascularization or no vascular alterations were noted in 21.4% of cases. Larger tumors (>21 mm) showed a 34.4% incidence of hypervascularization. No significant correlation was found between Doppler patterns and Gleason score.
Conclusions:
- Findings align with literature on the prevalence of perilesional vascularization in prostate neoplasms.
- Currently, echocolour and power Doppler do not offer significantly indicative patterns for diagnosing prostate neoplasia or guiding biopsies.
