Prostate cancer Patients who take great walks on a regular basis succeeds better than those who think the contrary, a new study suggests.
They not only reduce their risk of disease progression, they lower their chances of dying of the disease, researchers reported.
The conclusion is based on previous research in the same group of scientists who had indicated that "vigorous physical activity" reduces the risk of dying from prostate cancer.
"Men who participate in walking fast, defined as three miles per hour or faster, after clinically localized prostate cancer diagnosis had a reduction of the risk of progression of prostate cancer than men who walked to an easy pace less than two miles per hour"study author Erin said"" L. Richman, research associate in the Department of epidemiology and biostatistics at the University of California, San Francisco.
"Men who engaged in three hours per week or more brisk walking has had the greatest advantage", Richman added, "with a lower risk of 57% of the progression of the disease compared to men having come less than three hours per week at an easy pace." These results were independent clinical prognostic factors, dietary factors and factors of life such as obesity and smoking. ?
Report of the Richman appears in number 1 June of Cancer Research.
The authors of the study noted that about 2.2 million men are now struggling with a diagnosis of prostate cancer in the United States, and the disease is the second leading cause of cancer death in American men. In 2010, approximately 217,000 new cases were diagnosed.
To explore how lifestyle can influence the progression of the disease after a diagnosis, the study team focused on 1,455 patients with prostate cancer who were enrolled in one of the 40 Clinical Urology in 2004 and 2005.
At the time where the study launched, all men had localized cancer, which means that their disease had not yet spread beyond the prostate.
All the men completed a survey to assess their physical activity routines. Richman notes that most of the men had initially suffered "cure," including the radical treatment of prostactectomy or radiation.
The researchers found that walking represents approximately half of all physical activity exercised by patients, and that those that have been observed walking in so-called "deep" way tended to be younger and more appropriate than those who walked more slowly. Brisk walkers were also less likely to smoke.
By stacking patterns of exercise against signs of telltale of progression of the disease (such as the PSA levels, the spread of the disease or death), the research team found that patients who walked quickly for a minimum of three hours per week had a rate of progression of the disease (57 per cent below) significantly lesser than those who walked at an easy pace for less than three hours per week.
In fact, the pace of the March appeared to be more important than the amount of time spent walking. Walk at an easy pace conferred no advantage of protection against the progression of prostate cancer.
The team of the informed Richman that additional research is needed to confirm the results. She also suggested that other types of exercise may also be useful.
Mr. Lionel l. Banez, Assistant Professor in the division of Urologic Surgery, in the Department of surgery at Duke University Medical Center has agreed that further research might find that other forms of exercise provide similar protection.
"It's very reasonable to extrapolate these findings to include other forms of physical activity", he noted. "Our own previous study show that moderate exercise which included various forms of physical activity, has been associated with less aggressive prostate cancer risk in veterans."
