ASTRO and AUA issue joint guideline for radiation therapy after prostatectomy

Guideline provides detailed direction on treatment options for prostate cancer patients

2013-05-07
(Press-News.org) San Diego, May 7, 2013 – The American Society for Radiation Oncology (ASTRO) and the American Urological Association (AUA) are pleased to announce the publication of the joint guideline on radiation therapy after prostatectomy for patients with and without evidence of prostate cancer recurrence. The 81-page document represents an intensive collaboration among experts in the radiation oncology and urology fields, led by Richard K. Valicenti, MD, MA, professor and chair of the department of radiation oncology at the University of California Davis Comprehensive Cancer Center in Sacramento, on behalf of ASTRO, and Ian M. Thompson, MD, director of the Cancer Therapy and Research Center at the University of Texas Health Science Center at San Antonio and the Glenda and Gary Woods Distinguished Chair in genitourinary oncology, on behalf of the AUA.

The Adjuvant and Salvage Radiotherapy After Prostatectomy: ASTRO/AUA Guideline is a comprehensive review of 324 research articles of English-language publications within the Pubmed, Embase and Cochrane databases, published from January 1, 1990 through December 15, 2012. The guideline is available online free as a PDF document at http://www.redjournal.org and http://www.auanet.org, and will be published in the August 1, 2013, print issue of the International Journal of Radiation Oncology • Biology • Physics (Red Journal), the official scientific journal of ASTRO, and in the August 2013 print issue of the Journal of Urology, the official journal of the AUA.

The strategies and approaches recommended were derived from evidence-based and consensus-based processes in the reviewed articles. The systematic review included articles that provided detailed efficacy in patients with detectable and undetectable prostatic specific antigen (PSA) levels, toxicity and quality of life impact, and optimal imaging strategies to determine the appropriateness of radiation therapy use in patients suspected of recurrence. Only studies in which PSA data were provided for 75 percent or more patients were included in the guideline.

The guideline document provides the following clinical principles, recommendations, standards and options: 1) patients who are being considered for management of localized prostate cancer with radical prostatectomy should be informed of the potential for adverse pathologic findings that portend a higher risk of cancer recurrence; 2) patients with adverse pathologic findings including seminal vesicle invasion, positive surgical margins and extraprostatic extension should be informed that adjuvant radiation therapy, compared to radical prostatectomy only, reduces the risk of biochemical (PSA) recurrence, local recurrence and clinical progression of cancer; 3) physicians should offer adjuvant radiation therapy to patients with adverse pathologic findings at the time of prostatectomy, including seminal vesicle invasion, positive surgical margins or extraprostatic extension because of demonstrated reductions in biochemical recurrence, local recurrence and clinical progression; 4) patients should be informed that the development of a PSA recurrence after surgery is associated with a higher risk of development of metastatic prostate cancer or death from the disease; 5) clinicians should define biochemical recurrence as a detectable or rising PSA value after surgery that is ≥ 0.2 ng/ml with a second confirmatory level ≥ 0.2 ng/ml; 6) a restaging evaluation in the patient with a PSA recurrence may be considered; 7) physicians should offer salvage radiation therapy to patients with PSA or local recurrence after radical prostatectomy in whom there is no evidence of distant metastatic disease; 8) patients should be informed that the effectiveness of radiation therapy for PSA recurrence is greatest when given at lower levels of PSA; and 9) patients should be informed of the possible short-term and long-term urinary, bowel and sexual side effects of radiation therapy, as well as the potential benefits of controlling disease recurrence.

In addition to Drs. Valicenti and Thompson, authors of the The Adjuvant and Salvage Radiotherapy After Prostatectomy: ASTRO/AUA Guideline include Eric A. Klein, MD, of the Cleveland Clinic; S. Larry Goldenberg, MD, of the Vancouver Prostate Centre at the University of British Columbia; Peter C. Albertsen, MD, of the University of Connecticut Health Center; Jeff M. Michalski, MD, MBA, FASTRO, of the Siteman Cancer Center at the Washington University School of Medicine in St. Louis; Mack Roach, III, MD, of the Helen Diller Family Comprehensive Cancer Center at the University of California, San Francisco; Oliver Sartor, MD, of the Tulane University School of Medicine; Brian J. Davis, MD, PhD, of the Mayo Clinic; and Martha Faraday, PhD, of Four Oaks Inc.

"This guideline explicitly includes a multitude of significant clinical trial results from more than 20 years of thorough research," said Dr. Valicenti. "There is a critical need for evidence-based standards, recommendations and options to maximize our ultimate goal of increased patient survival and quality of life. This guideline is a compendium of the vast wealth of research available and provides a thorough treatment template for us to consider for prostate cancer patients after a radical prostatectomy."

"The work of the AUA and ASTRO staff, as well as our exceptional guideline panelists, was outstanding," said Dr. Thompson. "This guideline provides a very practical approach for the clinician to help guide in patient decision-making that will result in the very best patient outcomes."

The Adjuvant and Salvage Radiotherapy After Prostatectomy: ASTRO/AUA Guideline is jointly copyrighted by ASTRO and the AUA. It will serve as a new, living manifesto of both specialties' dedication to optimal patient care and outcomes and will be updated regularly.

"Many thanks to the dedicated efforts of Drs. Valicenti and Thompson for leading the extraordinary effort to issue this important document from both specialty organizations," said Michael L. Steinberg, MD, FASTRO, chairman of ASTRO's Board of Directors. "The Adjuvant and Salvage Radiotherapy After Prostatectomy: ASTRO/AUA Guideline is an essential tool for every practice as they determine the best treatment plan for prostate cancer patients after prostatectomy."

"We are very pleased that ASTRO and AUA came together to create this important document," said J. Stuart Wolf Jr., MD, FACS, chairman of the AUA's Practice Guidelines Committee. "By collaborating and cooperating, we have built on the strengths of both specialties to improve patient care."

Discovery of new hormone opens doors to new type 2 diabetes treatments

2013-05-07
Boston, MA — Harvard School of Public Health (HSPH) researchers have discovered that a particular type of protein (hormone) found in fat cells helps regulate how glucose (blood sugar) is controlled and metabolized (used for energy) in the liver. Using experimental models and state-of-the-art technology, the scientists found that switching off this protein leads to better control of glucose production from the liver, revealing a potential new target that may be used to treat type 2 diabetes and other metabolic diseases. The study appears online in the May 7, 2013 issue ...

The more feathers a male sparrow carries to the nest, the more eggs the female will lay

2013-05-07
An international team lead by the University of Granada has found that female sparrows will invest more energy into laying eggs according to the male's ability to fill the nest with feathers which serve to insulate the chicks from the cold and keep them alive. Scientists from the University of Granada, in collaboration with the South African University of the Witwatersrand and the Percy FitzPatrick Institute at the University of Cape Town, have discovered that the female house sparrow (Passer domesticus) invests more energy into laying eggs when the male brings more feathers ...

Laminopathies: Key components in the disease mechanism identified

2013-05-07
Laminopathies are hereditary diseases that affect mainly the muscle tissue. These diseases include for example Emery-Dreifuss Muscular dystrophy, dilated cardiomyopathy, limb-girdle muscular dystrophy and Hutchison-Gilford progeria syndrome. The underlying defect in these diseases is mutation in the genes encoding lamins or lamin-associated proteins. For example, many mutations in the lamin gene LMNA have been associated with different diseases. Lamins are crucial components of the nuclear lamina that underlies the inner side of nuclear envelope, and provides mechanical ...

High home ownership can seriously damage your labor market, new study suggests

2013-05-07
Government policies that boost the amount of home ownership in a country are likely to inflict severe damage on the labour market, new research from the University of Warwick suggests. Professor Andrew Oswald from the University of Warwick and Professor David Blanchflower from Dartmouth College examine a century of unemployment and home ownership data for the states of the USA from 1900 to 2010. Combining those numbers with modern data on millions of randomly sampled Americans, the researchers show there is a powerful link between the housing market and the later health ...

Chaos proves superior to order

2013-05-07
An international team of physicists, including researchers from the Universities of York and St. Andrews, has demonstrated that chaos can beat order - at least as far as light storage is concerned. In a collaboration led by the King Abdullah University of Science and Technology (KAUST), Saudi Arabia, the researchers deformed mirrors in order to disrupt the regular light path in an optical cavity and, surprisingly, the resulting chaotic light paths allowed more light to be stored than with ordered paths. The work has important applications for many branches of physics ...

Magnetic vortex antennas for wireless data transmission

2013-05-07
"So far, magnetic vortex states have been observed only in two dimensions; in other words: Within a plane," explains Sebastian Wintz, physicist at the Helmholtz-Zentrum Dresden-Rossendorf. These magnetic vortices typically occur in nanometer-scale magnetic disks. Wintz has now investigated three-dimensional magnetic layer systems together with his colleagues from HZDR and the Swiss Paul Scherrer Institute: The researchers stacked two magnetic disks at a time, which were separated by a thin non magnetic metal layer, on top of each other. Due to this special design, ...

Parents who suck on their infants' pacifiers may protect their children against developing allergy

2013-05-07
Swedish researchers at the Sahlgrenska Academy, University of Gothenburg, Sweden, report that a simple habit may give significant protection against allergy development, namely, the parental sucking on the baby's pacifier. Allergies are very common in industrialized countries. It has been suggested that exposure to harmless bacteria during infancy may be protective against the development of allergy. However, it has been difficult to pinpoint which bacteria a baby should be exposed to, and at what time and by which route this exposure should ideally occur. Swedish researchers ...

Period pain not made worse by copper IUD

2013-05-07
Previous scientific studies have suggested that women who use a copper IUD for contraception suffer from worse period pain, but a study at the Sahlgrenska Academy, University of Gothenburg, that followed 2,100 women over a 30-year period shows that this is not the case. In the study, 19-year-olds born in 1962, 1972 and 1982 were asked questions about their height, weight, pregnancies, children, period pain and contraception. The latest results, published in the leading journal Human Reproduction, reveal that women who use a copper IUD do not suffer from worse period ...

And the beat goes on...: The reliable heartbeat of hibernators

2013-05-07
To date, the mechanisms underlying the maintenance of cardiac function at low body temperatures are poorly understood. Now, scientists at the Research Institute of Wildlife Ecology at the University of Veterinary Medicine, Vienna, together with colleagues at the University of Groningen in the Netherlands, have found that certain omega-3 and omega-6 fatty acids regulate the cardiac function and hence hibernation. These fatty acids control the process of maintaining a regular heartbeat, achieving lower body temperatures during hibernation and thereby ensuring the hibernator's ...

Certain bladder-cancer patients may be at high risk of disease recurrence despite bladder removal

2013-05-07
DALLAS – May 7, 2013 – Patients with advanced bladder cancers that are surgically removed might need additional therapy to prevent recurrence in certain situations, a new UT Southwestern Medical Center study suggests. The five-year international study led by researchers at UT Southwestern validates the use of a marker panel to predict which patients are more likely to have a recurrence of cancer after bladder removal, thereby identifying those patients as good candidates for follow-up chemotherapy. The findings, published in the most recent edition of European Urology, ...
