Verification imaging for breast and nodal breast diseases: a Varian user’s experience

The complexity of radiotherapy for breast cancer has increased in recent years with the introduction of more conformal techniques such as IMRT (intensity-modulated radiation therapy) and VMAT (volumetric modulated arc therapy). Furthermore, sequential treatments such as photon boosts are now increasingly integrated into the whole breast treatment. MV imaging was, and is for many departments, […]

Measuring and explaining CBCT dose safety limits in radiotherapy: the Barts experience

Radiotherapy treatments typically deliver between 2Gy and 6Gy per day to treat patients with cancer. When dealing with such high radiation doses, safety and accuracy are paramount to ensure good patient outcomes. Over the last two decades, simple conformal treatments have been steadily discarded in favour of the more sculpted dose distributions available from intensity […]

Techniques for delivering smart adaptive radiotherapy

IMRT has been the gold standard technique for delivering radical radiation to most tumour sites for at least a decade. It is three-dimensional radiotherapy; plans sculpt dose towards the disease and away from organs at risk (OAR) in all three axes. These shapes are defined by the patient’s geometry at a single timepoint – the […]

External beam radiotherapy in thyroid cancer

Thyroid cancer is the most common endocrine malignancy, resulting in more than 300 deaths in the UK each year. It has a female preponderance and typically presents as an incidental finding on imaging or with a neck mass. There are three main groups: Differentiated, medullary and anaplastic carcinoma. Differentiated thyroid carcinoma has the highest incidence […]

IMRT for prostate cancer

The increased frequency of PSA testing has led to an increased diagnosis of early organ confined prostate cancer. Diagnosis is primarily made by histology, via TRUS-guided sextant biopsy or template biopsy which can provide improved localisation of cancer within the prostate. Staging is from digital rectal examination, from imaging with multi-parametric MRI (TNM staging), from […]

Radiotherapy treatment planning

In radical radiotherapy treatment we aim to accurately deliver a lethal dose of radiation to tumour cells while sparing any surrounding normal tissues. Radiotherapy treatment planning is the process undertaken to determine the most appropriate way to deliver the radiation in order to meet the clinical prescription. Rapid advances in technology and computing, particularly in […]

Radiation-induced second cancers in prostate cancer patients

Radiotherapy is a commonly used, potentially curative treatment modality in patients with localised and locally advanced prostate cancer. The development of a radiation-induced second primary cancer is a serious long-term side effect of radiotherapy treatment. Prostate cancer is the most common cancer in males in the UK, with a lifetime risk of one in eight. […]

Arc IMRT for head and neck cancer

Radiotherapy plays an integral role in the treatment of early and locally advanced stage head and neck cancers (HNC). Due to the anatomical location of these tumours and the close proximity to critical structures, the challenge at this tumour site is achieving local control while sparing the organs at risk (OAR), including the spinal cord, […]
