Dr Plowman’s special interests are directed towards improving cure rates in cancer, whilst reducing the side effects of therapy. He is an expert on both radiation therapy and chemotherapy.
In medical oncology, his main contribution has been the demonstration of the importance of adrenal sex steroid production in both breast and prostate cancer and he pioneered therapies aimed at interrupting these pathways in both diseases that have now become standard treatment across the world. He has a long term interest in advances in the radiotherapeutic methods to treat prostate cancer – both external beam conformal and seed brachytherapy – and hormonal methods of therapy, and focussed brain and body radiotherapy techniques (gamma and cyberknife). He has published around 300 original research papers in clinical oncology.
