New Study Reveals Hidden Lymph Node Cancer Despite Clear PSMA PET Scans
Pelvic Lymph Node Staging With PSMA PET in Prostate Cancer: Surgical Validation With Implications for Radiotherapy Planning - Ozen - The Prostate - Wiley Online Library BLUF (Bottom Line Up Front): A Turkish surgical study found that 12% of prostate cancer patients with negative PSMA PET scans still had microscopic cancer in their pelvic lymph nodes when examined after surgery. This important finding suggests that even advanced imaging can miss small amounts of cancer spread, which has significant implications for treatment planning—particularly for patients considering radiation therapy instead of surgery. The Promise and Limitations of Modern Imaging PSMA PET/CT scanning has revolutionized how doctors detect prostate cancer spread. This advanced imaging technique uses a radioactive tracer that attaches to prostate-specific membrane antigen (PSMA), a protein highly expressed on prostate cancer cells. When cancer has spread to lymph nodes, these scans can often detect it far better...
