Thyroid cancer typically has a good outcome following standard treatments, which include surgery, radioactive iodine ablation for differentiated tumours and treatment with thyrotropine hormone-suppressive levothyroxine. Thyroid cancers that persist or recur following these therapies have a poorer prognosis. Cytotoxic chemotherapy or external beam radiotherapy has a low efficacy in these patients. 'Target therapy' with tyrosine kinase inhibitors (TKIs) represent an important therapeutic option for the treatment of advanced cases of radioiodine refractory (RAI-R) differentiated thyroid cancer (DTC), medullary thyroid cancer (MTC) and possibly for cases of poorly differentiated (PDTC) and anaplastic thyroid cancer (ATC). ⋯ The objective of this overview is to present the current status of the treatment of advanced DTC, MTC, PDTC and ATC with the use of TKIs by describing the benefits and the limits of their use. A comprehensive analysis and description of the molecular basis of these drugs and the new therapeutic perspectives are also reported. Some practical suggestions are also given for the management to the potential side-effects of these drugs.

High-quality Linac-based Stereotactic Body Radiation Therapy with Flattening Filter Free Beams and Volumetric Modulated Arc Therapy for Low-Intermediate Risk Prostate Cancer. A Mono-institutional Experience with 90 Patients.
The aim of this phase II study was to evaluate the efficacy and toxicity of stereotactic body radiotherapy in patients with low or intermediate risk prostate cancer. ⋯ Stereotactic body radiotherapy delivered using linac-based flattening filter free volumetric modulated arc radiotherapy in low and intermediate risk prostate cancer patients is associated with mild toxicity profiles and good patient-reported quality of life.

Peer Review of Radiotherapy Planning: Quantifying Outcomes and a Proposal for Prospective Data Collection.
The Canadian Partnership for Quality Radiotherapy quality assurance guidelines recommend that radiation oncologist peer review of curative radiotherapy plans takes place ideally before the first fraction of treatment is delivered. This study documented and evaluated the outcomes of weekly, disease site-specific, radiotherapy peer review, quality assurance rounds at the Tom Baker Cancer Centre in Calgary, Canada with a view to making recommendations about the optimal timing and documentation of peer review during the radiotherapy planning processes. ⋯ 9% of radiotherapy plans reviewed had changes suggested before delivery to the patient. Review at the post-planning stage after plan completion was necessary to detect all suggested changes, but for head and neck cases, all C outcomes could have been detected at the post-contouring stage. More widespread implementation of radiotherapy peer review in the UK is recommended.

ReviewWhat is the Optimum Screening Strategy for the Early Detection of Lung Cancer.
Early diagnosis of lung cancer is currently the most effective way of reducing lung cancer mortality other than quitting smoking because the treatment of late stage disease has little impact. Improving the awareness of the risk of lung cancer and warning symptoms, recognition and prompt referral, and screening with low dose computed tomography (LDCT) are potential ways to improve early diagnosis. ⋯ Many of these questions are being answered by on-going European trials that are reporting their findings. Here we review the research evidence for LDCT screening and explore the important issues that need to be addressed to optimise effectiveness.

Organisation of Prostate Cancer Services in the English National Health Service.
The National Prostate Cancer Audit (NPCA) started in April 2013 with the aim of assessing the process of care and its outcomes in men diagnosed with prostate cancer in England and Wales. One of the key aims of the audit was to assess the configuration and availability of specialist prostate cancer services in England. ⋯ The organisational survey of the NPCA has provided a comprehensive assessment of the structure and function of specialist MDTs in England and the availability of prostate cancer procedures and services. As part of the prospective audit, the NPCA will assess the effect of the availability of prostate cancer services on access regionally and subsequent outcomes of care according to evidence-based guidelines.
