Adjuvant hormonal therapy added to radiation therapy for localized prostate cancer
Prof J Armstrong, Consultant Radiation Oncologist at UCD, examines the biological behaviour and treatment of prostate cancer
The biological behaviour of prostate cancer can be predicted using clinically- available data. The combination of clinical stage, tumour grade (usually described as Gleason score, a method of grading histology — high scores have a bad prognosis) and the level of prostate specific antigen (PSA) can be used to predict the risk category of individual patients. The TNM staging system is described it Table 1.
