Combining Radiation Modalities Increases Prostate Cancer Cure Rates

02.08.2004


High-risk prostate cancer patients who undergo a combination of hormonal therapy, radioactive seed implant (also called brachytherapy) and external beam radiation therapy are shown to have an increased chance of cancer cure, according to a new study published in the August 1, 2004, issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.



Historically, high-risk prostate cancer has been a therapeutic challenge for physicians, despite their efforts to cure patients by aggressively treating them with either surgery, brachytherapy or external beam radiation. Previous studies have shown the 5-year freedom from recurrence rates for high-risk patients treated with just one of these treatments to be between 0 and 50 percent, with up to half of these failures occurring where the original tumor was found.

To see if combining therapies would decrease recurrence rates for men with high-risk prostate cancer, 132 patients with high Gleason scores, with high prostate-specific antigen (PSA) scores or who were at an advanced clinical stage of prostate cancer were studied. A three-pronged approach that included brachytherapy, external beam radiation therapy and hormonal therapy produced an 86 percent rate of freedom from recurrence after five years. In addition, 47 of the original 132 patients in the study had a prostate biopsy performed two years after the end of treatment and 100 percent of them showed no evidence of the cancer recurring.


“This is a very exciting study because it shows that this new approach of combining brachytherapy, external beam irradiation and hormonal therapy to cure prostate cancer can be very effective for men with aggressive forms of the disease,” said Richard G. Stock, M.D., lead author of the study and Chairman of the Department of Radiation Oncology at the Mount Sinai School of Medicine in New York. “The data also supports the theory that enhanced local control can improve overall disease control.”

ASTRO is the largest radiation oncology society in the world, with more than 7,500 members who specialize in treating patients with radiation therapies. As a leading organization in radiation oncology, biology and physics, the Society is dedicated to the advancement of the practice of radiation oncology by promoting excellence in patient care, providing opportunities for educational and professional development, promoting research and disseminating research results and representing radiation oncology in a rapidly evolving socioeconomic healthcare environment.

Im Focus: Data storage using individual molecules

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Personal patches could reduce energy waste in buildings, Rutgers-led study says

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
