[Efficient diagnosis of prostate carcinoma]

Area of Science:

• Urology
• Oncology
• Diagnostic Imaging

Background:

• Definitive diagnosis of prostate cancer often relies on physical examination findings.
• Current laboratory measures lack sufficient accuracy for early prostate cancer diagnosis.
• Metastatic spread influences specific biochemical markers like acid phosphatase and urine hydroxyprolin.

Purpose of the Study:

• To review and discuss current scientific methods for diagnosing prostate cancer and its spread.
• To evaluate the efficacy and limitations of various diagnostic techniques.
• To guide clinicians on appropriate diagnostic pathways based on clinical findings.

Main Methods:

• Review of diagnostic procedures including rectal examination, biopsies, and laboratory tests.
• Evaluation of imaging techniques such as lymphography, bone scanning, and X-rays.
• Discussion of surgical staging procedures like lymphadenectomy and minimally invasive biopsies.

Main Results:

• Rectal examination findings necessitate biopsy for accurate prostate cancer diagnosis.
• Acid phosphatase and urine hydroxyprolin levels are indicative of metastatic disease.
• Trans-cutaneous fine needle biopsy of lymph nodes shows promising results for staging.
• Bone scanning is valuable for detecting bone metastases, often confirmed by X-ray.

Conclusions:

• Biopsy remains the gold standard for diagnosing prostate cancer when palpation is suspicious.
• Staging lymphadenectomy is reserved for curative treatment due to high complication rates.
• A combination of imaging and biopsy techniques is crucial for comprehensive staging and diagnosis.
