Association of recurrence patterns and outcome with HR and HER2 status in patients with resected brain metastases from breast cancer

International Journal of Cancer, EarlyView.
What's New? While treatment strategies for solid brain metastases have been relatively uniform across cancer subtypes, tailored approaches are warranted. In this observational study, intracranial recurrences after microsurgical resection occurred significantly earlier and more frequently at distant sites in patients with triple‐negative breast cancer ...

Spine SBRT using VMAT

Journal of Physics: Conference Series, 2017
Metastases of the spinal column are common amongst cancer patients with approximately 18,000 new cases in North America each year that require urgent treatment. Historically radiation therapy doses have been limited due to the proximity of the spinal cord.

Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Stabilised Hyaluronic Acid Gel Rectal Spacers in MRI‐Guided Brachytherapy for Gynaecological Cancers: A Prospective Feasibility Study

Journal of Medical Radiation Sciences, EarlyView.
This prospective study investigated the feasibility of stabilised hyaluronic acid gel as a rectal spacer in gynaecological cancer brachytherapy. In twelve patients, the spacer was successfully inserted into the rectovaginal space without serious adverse events, had high visibility on MRI, increased the target‐to‐rectum distance compared with no spacer ...

Comparative Evaluation of Four Stereotactic Radiosurgery Planning Approaches for Treatment of Posterior Choroidal Melanoma

Journal of Medical Radiation Sciences, EarlyView.
This study evaluated four stereotactic radiosurgery planning approaches for posterior choroidal melanoma (CM). Analysis of thirteen CM cases resulted in a clinically meaningful reduction in dose to the brain for Brainlab Elements modulated arcs (BE) and Varian Eclipse HyperArc modulated arcs (HA) compared to Brainlab iPlan dynamic conformal arc therapy
