What is required to confirm the presence of prostatic carcinoma?

• A. CT scan of the abdomen
• B. Prostate biopsy
• C. Serum PSA levels
• D. Digital rectal exam

Answer: (B)

The confirmation of prostatic carcinoma primarily relies on the histological examination of prostate tissue obtained through a biopsy. A prostate biopsy allows for the collection of tissue samples that can be examined microscopically, enabling pathologists to identify cancerous cells and assess the grade and stage of the tumor. This definitive diagnosis is essential since many conditions can elevate prostate-specific antigen (PSA) levels or cause abnormalities detectable on imaging studies or physical exams, but only a biopsy can provide the conclusive evidence of malignancy. While imaging techniques, such as a CT scan, can be useful in staging the disease or assessing metastasis, they do not confirm the presence of prostate cancer. Serum PSA levels are important for screening and monitoring, but elevated levels alone cannot distinguish between benign prostatic conditions and cancer. Similarly, a digital rectal exam can indicate abnormalities in the prostate but cannot definitively diagnose cancer either. Therefore, the prostate biopsy is the gold standard required for the confirmation of prostatic carcinoma.
