Is choline PET useful for identifying intraprostatic tumour lesions? A literature review.

摘要: More than 80% of patients with intermediate-risk or high-risk localized prostate cancer are cured radiation doses 74-78 Gy, but high increase the risk for late bowel and bladder toxicity among long-term survivors. Dose painting, defined as dose escalation to areas in containing tumour, rather whole gland, minimizes normal tissues hence toxicity. It requires accurate identification location size these lesions, which functional MRI is current gold standard. Many studies have assessed use choline PET staging newly diagnosed patients. This review will discuss important imaging variables affecting accuracy scans, how contributes tumour used radiotherapy planning can improve patient pathway involving radiotherapy. In summary, available literature shows that improves higher tracer delayed (although optimal uptake time unclear), by improved addition imaging. We propose future research prolonged multiphase imaging, may further accuracy.
