New biopsy technique improves prostate cancer detection effectiveness

Researchers in the U.K., led by the University of Oxford, have discovered a new prostate biopsy method that improves cancer detection. However, it takes longer and is more painful for patients. Prostate cancer is the most common cancer in developed countries. The usual biopsy method uses a needle inserted through the rectum, performed under local anesthetic. This method has raised concerns about infection risks. In a recent trial published in The Lancet Oncology, scientists studied 1,126 men who were being checked for prostate cancer. They compared the traditional "transrectal" approach with the new "transperineal" method, which uses a needle through the skin. The goal was to determine which method better identifies significant cancers needing treatment while also monitoring complications like infections. Biopsies were performed in clinics with local anesthetic, and patients reported their experiences before and after the procedure. Professor Richard Bryant stated the findings are crucial for helping doctors and patients make informed decisions about biopsy methods. The results showed that the transperineal method is more effective in diagnosing important prostate cancers and does not require antibiotics, which is a benefit in terms of reducing antibiotic resistance. However, patients reported more pain and the procedure took longer. Dr. Alastair Lamb, co-leader of the study, noted that despite the benefits of the new method, it has some drawbacks, including the increased time and costs associated with it. He emphasized that ongoing research aims to find even less invasive ways to diagnose prostate cancer. This study provides important evidence to help with the decision-making process regarding which biopsy technique to use for prostate cancer.
