Advances in technology, clear clinical benefits will drive more cancer doctors to use protons

140806_Steven_Frank
The latest technical advancement in proton therapy is already providing such compelling early evidence of its benefit for patients, a leading radiation oncologist predicts it will become standard treatment for many cancers.   In use at MD Anderson Proton Therapy Center in Houston, Texas, for more than three years now, intensity modulated proton therapy (IMPT) permits doctors to treat one tiny section of a tumor at a time — even as small as a pixel — by adjusting the proton beam dose, direction and depth to wider and narrower contours of the target, while significantly reducing the amount of unintentional radiation hitting nearby healthy tissue.   IMPT pairs the precision of pencil beam scanning with the latest three-dimensional imaging technology to map the...

WEB REVIEW – Rising preference for non-surgical treatment

According to a new report by Global Industry Analysts, cancer patient show a rising preference for radiation therapy over surgical treatment options. Radiation therapy involves the use of high-energy radioactive particles or electromagnetic waves to destroy cancer cells, shrink tumors and repair physiological abnormalities. The growth in the radiation therapy equipment market is primarily driven by rising incidence of cancer (due to aging population, lifestyle changes, dietary habits, and high smoking rates), but is also fueled by technological improvements in molecular and...

Proton beams are big guns against HPV-related oropharyngeal cancers

Doctor Alexander Lin
Radiation oncologists are using protons against a growing number of oropharyngeal cancers caused by the human papilloma virus (HPV). “We’re seeing a decrease in smoking-related head and neck cancers and an increase in HPV-related oropharyngeal cancers,” said Alexander Lin, MD, clinical operations director at Penn Medicine’s Roberts Proton Therapy Center in Philadelphia, Pennsylvania. Penn Medicine is the branded... Full article

Web review – Next generation proton therapy in Texas

Intensity modulated proton therapy treatment (IMPT) is now available at MD Anderson Cancer Center in Houston, Texas. This new technology further refines radiation therapy options for complicated head and neck tumors. Selected for its ability to target tumors precisely while minimizing damage to healthy surrounding tissue, proton therapy has rapidly gained a foothold as an option for radiation treatment in the past decade. The Proton Therapy Center at The University of Texas MD Anderson Cancer Center in Houston, Texas, opened in 2006, is now one of 10 proton therapy centers currently... Full article

Monte Carlo simulation helps improve dosing

SBLee
Researchers at the National Cancer Center of Korea are using the Monte Carlo method to achieve more precise dose calculation for patients treated with proton therapy. “Sometimes we cannot treat with our proton beam modality because our commercial treatment planning system cannot calculate dose distribution for complicated anatomy,” says Se Byeong Lee, Ph.D., chief medical physicist, National Cancer Center of Korea....

UFPTI explores hypofractionation

Nancy_Mendenhall
Proton therapy clinicians are exploring the benefits and risks of treating slow-growing cancers with higher individual proton doses over a more accelerated time frame, cutting the total treatment period by a third or more. “If the same tumor control goal can be accomplished safely in a shorter time with fewer proton fractions, it could have a huge benefit on health outcomes,” says Nancy Mendenhall, M.D., Clinical...

Cone Beam CT allows for greater accuracy in treatment

Cone Beam CT Black 3D Picture
A new imaging technology promises to accommodate for anatomy and tumor changes to achieve better patient positioning and promote adaptive treatment, allowing clinicians to modify treatment protocols so they fit the immediate needs of cancer patients undergoing proton therapy. Cone Beam computed tomography (Cone Beam CT) gives proton therapy clinicians and physicists the ability to use 3-D volumetric imaging, which... Full article

Proteus ONE: compact PT solution

Proteus ONE
Ion Beam Applications (IBA) presented its compact advanced PT system, Proteus ONE™, at ASTRO annual meeting. A full-size model of the system was displayed to showcase its unique structure and benefits. Proteus ONE is a single-room configuration consisting of an accelerator, a direct beam line and a compact gantry. It is a significantly smaller version of any current proton beam systems and operates similarly. When... Full article

A new nozzle for uniform proton beam scanning

MatriXX
For years now, if proton therapy practitioners wanted to benefit from a uniform dose distribution when using active scanning techniques, they needed their facility to design and develop a uniform scanning dedicated system. In fact, medical physicists at three different proton therapy centers in the world did just that, at considerable time and expense. But such an enormous R&D investment will no longer be required....

PBS, the future of proton therapy

the future of proton therapy
A team of researchers, clinicians and physicists from Belgium, Korea, Massachusetts and Florida is working to create the future of proton therapy. Though geographically dispersed, their ideological aim is extremely focused: to develop, test and ultimately deliver a new form of proton therapy to patients: Pencil Beam Scanning (PBS). Currently, the most prevalent form of proton therapy delivery is double or single... Full article
