Highly experienced in the treatment of gastrointestinal, hepatobiliary and head and neck cancers, Dr Sibtain is skilled in the latest and most advanced therapies, including:
Intensity modulated radiotherapy (IMRT)
Radiotherapy is the use of high-energy radiation to destroy or shrink cancerous tumours. It may be used alone or in combination with chemotherapy (chemoradiotherapy) to try to cure the cancer, before surgery to reduce the size of the tumour to make removal easier, or after surgery to destroy any tumour that may be left. Radiotherapy delivered by a machine outside of the body is known as external radiotherapy, and until recently external radiotherapy machines could only deliver an untargeted beam of same dose radiation that reached surrounding healthy tissue as well as the tumour.
Intensity modulated radiotherapy (IMRT) uses advanced technology to shape the radiotherapy beam to the exact size and shape of the tumour, avoiding damage to surrounding healthy tissue. Precise and varying doses can be applied to different areas of the tumour, maximising the effectiveness of the therapy and reducing side-effects.
Stereotactic radiosurgery (also known as stereotactic radiotherapy) is another new technology to deliver targeted radiation to a tumour. Most commonly used for small brain tumours such as acoustic neuroma, secondary brain tumours, menigioma and pituitary tumours, it involves the application of a very high dose of radiation to a very small precise area.
Stereotactic radiosurgery can be delivered from specialised machines (Gamma Knife and CyberKnife), or from a conventional radiotherapy machine (linear accelerator) that has been adapted for the purpose. Totally non-invasive and with an excellent record for successful treatment, it does not result in hair loss or nausea and patients can normally resume everyday activities within a couple of days.
