前列腺癌放射性核素治療 (Only available in Cantonese)

(Only Available in Cantonese) [傳媒訪問] 香港電台：精靈一點 — 前列腺癌放射性核素治療 男士年過五十，患上前列腺癌的風險因素便會增加，而隨著醫療科技進步，前列腺癌的治療亦取得了發展。中大醫院臨床腫瘤科專科醫生鄭志堅醫生指，除了傳統的手術、藥物，及外放射治療之外，內放射治療（例如：放射性藥物治療 (鐳-223) 或 靶向放射配體療法 (鑥-177-PSMA) 等 ）亦是某些病人在處理前列腺癌時的其中一個選擇。鄭醫生亦補充，在考慮選用哪一種放射性核素以進行治療時，除了癌症的期數外，亦需檢視一系列的因素，例如：PSA指數（前列腺特異抗原）、癌症轉移的狀況及患者的其他病史等。 重溫連結： https://bit.ly/CUHKMC_RTHK_AC_20230510

Imaging and Diagnosis of Prostate Cancer

Traditionally, men with elevated PSA would require transrectal ultrasound-guided prostate biopsy to look for any prostate cancer. However, transrectal approach has a 1-2% chance of severe infection, and the biopsy procedure may also be prone to sampling error.  Recently, there have been a lot of advances in prostate cancer diagnosis. For men with elevated PSA, a MRI scan can be arranged to look for any tumours or suspicious lesions within the prostate gland. The MRI images can be fused into the ultrasound image during prostate biopsy, and targeted biopsy of the prostatic tumour can be performed. This will increase the accuracy of the biopsy procedure. On the other hand, if the MRI scan shows a completely normal prostate gland, prostate biopsy may also be safely avoided.    Conventional transrectal prostate biopsy requires puncture of the rectal wall, and bacteria within the rectum may enter the body and result in infection. In order to reduce the risk of infection, transperineal prostate biopsy can be performed. The perineum will first be disinfected during the procedure, and the perineal skin will be punctured in order to sample tissue from the prostate gland. The rectal wall remains intact during the whole prostate biopsy procedure, therefore bacteria within the rectum would not be able to enter the bloodstream. In recent years, transperineal prostate biopsy has gained increasing interest and adoption globally. For patients with confirmed prostate cancer, it is important to look for any distant metastasis before deciding on the appropriate treatment. PSMA PET-CT scan is an accurate imaging for staging prostate cancer. In patients with localized disease, curative treatment such as robotic surgery, radiotherapy and focal therapy can be considered. In patients with metastatic prostate cancer, medical treatment such as hormonal therapy and chemotherapy may be considered.
