Thousands of miles from his Austin, Texas, home, endurance athletes coached by Bill Earthman are training for grueling, day-long tests of strength and stamina like no other: the Ironman Triathlon.   Bill’s athletes live and train in the U.S., the U.K., South Africa, Peru, Mexico and Australia. And they may travel to nearly every continent of the world to compete in Ironman Triathlon series events.   Participants first must swim 2.4 miles. Then, they immediately bike a 112-mile route. And finally, they run 26.2 miles. All in 17 hours or less, challenged by weather, waters and terrain unique to the venue — and by the body’s creeping levels of lactic acid that can cripple an athlete’s performance.   “You don’t want to work too hard or work too...

  Harmful spillover radiation to the bowels, stomach and liver has soured many cancer physicians on using conventional radiation concurrently with chemotherapy or surgery for treating gastrointestinal (GI) cancers.   But the lesser side effects of highly targeted proton radiation may dramatically change the negative perceptions about using radiation for GI cancers.   “Conventional...

Proton clinicians are setting sights on Hodgkin and non-Hodgkin lymphomas

Lymphomas are the new targets for protons. Primarily preferred for treating solid mass tumors, protons are now being viewed as a prudent type of radiation for treating Hodgkin and non-Hodgkin lymphomas. About 9,000 Americans are diagnosed with Hodgkin lymphoma every year. And more than 65,ooo Americans are diagnosed with non-Hodgkin lymphoma annually. According to Brad Hoppe, M.D., M.P.H, a radiation oncologist at... Full article

Hodgkin lymphoma study shows prospect of long-term benefits of proton therapy

Smaller amounts of spillover radiation to healthy tissue and organs have heightened interest in using protons to treat Hodgkin lymphoma.   In the first-of-its-kind study, prospectively comparing radiation dose to normal tissue for involved-node proton therapy with three-dimensional conformal radiation therapy (3DCRT) and intensity modulated radiation therapy (IMRT) in Hodgkin lymphoma patients, the mean dose of...

Treatment for salivary cancer didn’t curb man’s passion for travel and food

Stan Williams is hatching another trip with his wife. This time to New Orleans, Louisiana. Just three months ago, they had explored the gorgeous rainforests and beaches of Belize. And before that, they were strolling the neighborhoods of New York City. “Stephanie wants to go to the French Quarter,” Stan says. “And we’ll take a boat ride down the bayou. I really just like to taste the flavors of the city and back... Full article

Study looks at value vs. cost in proton and X-ray therapy delivery

A proof of concept study from the University of Texas MD Anderson Cancer Center shows that the episodic cost of care using intensity modulated proton therapy (IMPT) in advanced-stage head and neck cancer is less than that of intensity modulated radiation therapy (IMRT), also known as X-ray or photon therapy. The study, “Defining the Value of Proton Therapy,” published in Oncology Payers, detailed findings concerning... Full article

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

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...

Numbers, types of proton therapy clinical studies on the rise

With 14 proton therapy centers currently operating in the United States and an additional 28 up and running worldwide, studies on the efficacy of using proton beam therapy for cancer treatment are being more widely conducted now than ever before. “Ten years ago, there were only three proton centers operating in the United States, so the number of patients who were being treated and actually could be included in...

5 years after proton beam therapy, most prostate cancer patients are disease-free and living a normal life, study reports

According to Dr Mendenhall, the number of cancer-free men previously diagnosed with mid-level prostate cancer is of particular significance
A long-term outcomes study of prostate cancer patients treated with image-guided protons may begin to dispel questions about the efficacy of proton therapy and its impact on patient quality of life. For five years, clinicians at the University of Florida Proton Therapy Institute in Jacksonville, Florida, tracked the ongoing health of 211 men. Each had been diagnosed with low-, intermediate- or high-risk prostate cancer.... Full article

Some lung cancers may see benefits from few larger daily doses of protons

Dr Daniel Gome
Higher doses of proton beam radiation may be a worthwhile treatment alternative for some lung cancer patients.   Radiation oncologists at MD Anderson Cancer Center and MD Anderson Proton Therapy Center in Houston, Texas, are taking a lead in evaluating the use of fewer, larger-sized fractions of a total proton dose to treat early and more advanced lung cancers. This clinical approach is called hypofractionated... Full article

Study shows proton therapy cuts risk of secondary tumors nearly in half compared to photon radiation

Names of people separated by commas
A study published in the International Journal of Radiation Oncology • Biology • Physics has shown that proton therapy reduces the risk of a patient developing a second tumor by nearly half as compared with conventional radiation (photon) therapy. The impetus for doing the study was to see if the improved dose distribution achievable with protons as compared with photons would translate into a reduced rate for... Full article
