Rectal Spacer Gel Enhances Prostate Cancer Radiotherapy Precision, Reduces Side Effects
AM730 · 1 SOURCESabout 1 hour ago2 MIN

Summary
Hong Kong urologists are employing an innovative rectal spacer gel to enhance radiotherapy precision for prostate cancer patients. The hyaluronic acid-based gel, inserted between the prostate and rectum before treatment, creates a protective barrier that enables doctors to deliver higher radiation doses while minimizing damage to adjacent organs. This advancement not only reduces complications such as rectal bleeding and urinary pain but also allows for more comprehensive treatment of potential cancer spread, potentially lowering recurrence rates.
Key Points
- Prostate cancer ranks as the third most common cancer among men in Hong Kong, with treatment options including surgery, radiotherapy, and hormone therapy
- Radiotherapy carries significant risks because the prostate sits adjacent to the rectum and bladder, potentially causing diarrhea, anal discomfort, rectal bleeding, dysuria, and hematuria
- The rectal spacer gel is composed of hyaluronic acid, is absorbable over time, and is not a permanent implant; the insertion procedure mirrors transperineal prostate biopsy
- By separating the prostate from the rectum, the gel allows doctors to safely expand the radiotherapy field to include surrounding tissues where microscopic cancer spread may occur
- Dr. Lin Peihong, a urology specialist, notes that while lowering radiation energy reduces complications, it also diminishes therapeutic effectiveness, making the spacer an optimal compromise
Why It Matters
For Hong Kong men facing prostate cancer diagnosis, this technique offers a balanced approach that addresses both treatment efficacy and quality of life concerns. By enabling more aggressive yet safer radiotherapy, the spacer gel may improve long-term survival outcomes while reducing the burden of treatment-related complications that significantly impact daily living .
