Summary
Sonographic texture of prostate cancer varies with tumor size and histology. Hypoechoic patterns are common in smaller tumors, while larger tumors show mixed echogenicity, impacting diagnostic accuracy.
Area of Science:
- Urology
- Radiology
- Oncology
Context:
- Prostate cancer diagnosis relies on imaging and biopsy.
- Transperineal biopsy is a common method for obtaining prostate tissue samples.
- Sonographic appearance can aid in characterizing prostate lesions.
Purpose:
- To correlate sonographic findings of prostatic carcinoma with histopathologic features.
- To analyze the relationship between tumor size, echogenicity, and histopathology in prostate cancer.
Summary:
- This study analyzed 57 patients with prostatic carcinoma, correlating sonographic appearance with histopathology after transperineal biopsy.
- Smaller (≤2 cm) circumscribed lesions showed a prevalence of hypoechoic forms (61.9%).
- Larger (>2 cm) diffuse lesions exhibited mixed echogenicity (50%), hypoechoic (27.8%), and isoechoic (22.2%) patterns.
Impact:
- Sonographic texture variations in prostate cancer are linked to tumor size and histopathologic characteristics.
- Understanding these variations can potentially improve the interpretation of ultrasound in prostate cancer evaluation.
- This correlation aids in refining diagnostic approaches for prostate cancer.
