摘要

Each year, more than 5,000 men in Australia and New Zealand are diagnosed with locally advanced prostate cancer. Unfortunately, in at least 25% of cases, the cancer has metastasized to the bone and lymph glands, and is undetectable by current imaging methods. As a result, these men cannot undergo active surveillance and instead require treatment for prolonged periods. Although long-term androgen suppression following radiotherapy has been shown to be more effective than short-term androgen suppression (STAS), longer-term treatment is also associated with greater morbidities, such as osteopenia and fractures. The Trans-Tasman Radiation Oncology Group (TROG) 96.01 trial determined the value of 6 months of STAS. In the USA and Europe, androgen suppression lasting 28-36 months was frequently used after other trials showed that longer duration could reduce prostate cancer mortality. However, long-term and sometimes permanent side effects included sexual dysfunction, hot flushes, breast enlargement and pain, shrinkage of the genitalia, anaemia, blood clots, fatigue, cognitive dysfunction, depression and reductions in bone mineral density resulting in fractures.
