Stereotactic ablative radiotherapy: A potentially curable approach to early stage multiple primary lung cancer
Surgical resection has been the standard treatment for early stage multiple primary lung cancer (MPLC). However, a significant proportion of patients with MPLC cannot undergo surgery. For this report, the authors explored the role of stereotactic ablative radiotherapy (SABR) for patients with MPLC.

Brave cancer fighter Katie is learning to walk again
Five-year-old Katie Dodd is making a stand against the cancerous tumour which left her unable to walk. Katie’s parents Lee and Rebecca feared she may never walk again after doctors discovered a tumour pressing on her spinal cord last September. Since then, the Farnworth youngster has had 13 cycles of chemotherapy and travelled to America for Proton Beam Therapy.

Final analysis of intergroup randomized phase III study of androgen deprivation therapy and radiation therapy in locally advanced prostate cancer
Researchers presenting at the 68th annual meeting of the Canadian Urological Association said the combination of androgen deprivation therapy plus radiation therapy improves both overall and disease-specific survival in patients with locally advanced prostate cancer, compared with ADT alone, and should be considered standard of care for this group of patients.

Correlation of dynamic changes in gamma-H2AX expression in peripheral blood lymphocytes from head and neck cancer patients with radiation-induced oral mucositis
Research published in Radiation Oncology, to evaluate the role of gamma-H2AX in peripheral blood lymphocytes as a predictive biomarker of the severity of oral mucositis in head and neck cancer patients with receiving radiotherapy.

Frameless fractionated stereotactic radiation therapy of intracranial lesions: impact of cone beam CT based setup correction on dose distribution
The purpose of this study, published in Radiation Oncology, was to evaluate the impact of Cone Beam CT based setup correction on total dose distributions in fractionated frameless stereotactic radiation therapy of intracranial lesions.

Abstract: Prediction of rectum and bladder morbidity following radiotherapy of prostate cancer based on motion-inclusive dose distributions
In radiotherapy of prostate cancer the key organs at risk – the rectum and the bladder – display considerable motion, which may influence the dose/volume parameters predicting for morbidity. This study compared motion-inclusive doses to planned doses for the rectum and bladder and explored their associations with prospectively recorded morbidity.

A New Cyber Concern: Hack Attacks on Medical Devices
The FDA has issued guidelines to manufacturers of medical devices to protect their products from malware. The article states: “Computer viruses do not discriminate. Malware prowling the cybersphere for bank information and passwords does not distinguish between a home computer or a hospital machine delivering therapy to a patient. Even if a radiation therapy machine, say, is infiltrated unintentionally, malware could theoretically cause radiation doses to spike.”

High-Tech Treatments Increasingly Used in Low-Risk Prostate Cancer
In the United States, the use of advanced treatment technologies has increased among prostate cancer patients who are unlikely to benefit, according to a new study. Therapies such as intensity-modulated radiotherapy and robotic prostatectomy are being increasingly utilized in men with low-risk disease and/or a low risk of dying from prostate cancer. The study appears in the June 26 issue of JAMA.

Intensity-modulated radiotherapy versus three-dimensional conformal radiotherapy for stage I-II natural killer/T-cell lymphoma nasal type: dosimetric and clinical results
This study was to compare radiotherapy treatment planning and treatment outcomes following three-dimensional conformal radiotherapy (3DCRT) and intensity-modulated radiotherapy (IMRT) in stage I-II natural killer (NK)/T-cell lymphoma. Conclusions: IMRT provided better dose coverage than 3DCRT, although it failed to provide LCP and OS benefits.
