Dosimetric comparison of different dose calculation algorithms in postmastectomy breast cancer patients using conformal planning techniques

Journal of Medical Physics, 2023
Background: The aim of the current study was to compare three different dose-calculating algorithms, i.e., superposition (SP), fast SP (FSP), and convolution (CV), for breast cancer patients treated with intensity-modulated radiotherapy (IMRT) and field ...

Intensity-modulated radiotherapy for prostate cancer

Translational Andrology and Urology, 2018
Radiation therapy (RT) is a curative treatment modality for localized prostate cancer. Over the past two decades, advances in technology and imaging have considerably changed RT in prostate cancer treatment. Treatment has evolved from 2-dimensional (2D) planning using X-ray fields based on pelvic bony landmarks to 3-dimensional (3D) conformal RT (CRT ...

Monitor units are not predictive of neutron dose for high-energy IMRT

Radiation Oncology, 2012
Background Due to the substantial increase in beam-on time of high energy intensity-modulated radiotherapy (>10 MV) techniques to deliver the same target dose compared to conventional treatment techniques, an increased dose of scatter radiation ...

Intensity-modulated Radiotherapy for the Treatment of Breast Cancer [PDF]

Clinical Oncology, 2013
In the systematic review of intensity-modulated radiotherapy (IMRT) in the treatment of breast cancer reported in Clinical Oncology by Dayes and colleagues [1], the only prospective randomised clinical trial (n = 306) testing forward-planned IMRT to have reported a 5 year outcome for adverse effects [2] was excluded on the spurious grounds that no ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Advances in Intensity-Modulated Radiotherapy Delivery

, 2008
Fixed-field intensity-modulated treatments, delivered by conventional linac-plus-multileaf systems, have rapidly become the most common form of IMRT. Several innovative alternative IMRT options are also now available, including tomotherapy, CyberKnife and jaws-only linacs. These innovative approaches have divergent rationales.
