Does Surgery or Radiation Benefit Older Men w/Early-Stage Prostate Cancer and Other Health Problems?

Wednesday, May 21st, 2014

logo1267406_mdA new study in the early online edition of Cancer concluded that treating older men with early-stage prostate cancer who also had other serious health problems with aggressive therapies such as surgery or radiation therapy does not help them live longer and may be detrimental. The retrospective study followed more than 140,500 men ge 68 and older diagnosed with early stage prostate cancer between 1991 and 2007. Men were followed for 15 years after diagnosis and the Charison Index that can predict 10 year mortality for a patient who has a range of other health problems was used. A protstate cancer patient with diabetes may score 1 on the index, whereas a man with multiple or more severe health problems might score a 3 or higher. Findings showed that men with a Charison index score of 0,1, or 2 who were treated with surgery or radiation therapy had a lower risk of dying of prostate cancer compared to men receiving no treatment. However, men with scores of 3 or higher did not have a reduction in risk of death from cancer with aggressive treatment because they did not live long enough to benefit from it and were more likely to die from something else. They said that men who also had multiple medical conditions such as a history of heart attack, chronic obstructive pumonasry disease, and diabetes in combination did not live longer after agressive treatment compared with men receiving no treatment and were also at risk of side effects such as impotence, urinary incontinence and bosel problems that can result from surgery and radiation treatment. Researchers said “The guidelines suggest the men with life expectancies of less than 10 years shouldn’t be treated aggressively, but life expectancy is difficult to measure accurately. This data clearly defines a subset of patients who should avoid therapies that will only cause them problems they don’t already have.”

Can Multivitamins and Minerals Protect Older Women with Invasive Breast Cancer?

Wednesday, October 16th, 2013

logo1267406_mdA new study published in Breast Cancer Research and Treatment concluded that postmenopausal women who develop invasive breast cancer may benefit from taking supplements including multivitamins and minerals. Researchers of this very large study group found that the risk of dying from invasive breast cancer was 30% lower among women using multivitamin/minerals that among non users. Authors said “Our study offers tentative but intriguing evidence that multivitamin/mineral supplements may help older women who develop invasive breast cancer survive their disease.”

Overall Research Data was collected from 161,608 women post menopausal women between ages 50 and 79 from 40 clinical centers throughout the USA. in the years 1093 to 1998. Research on this study was collected from 7,728 women in this group who were diagnosed with invasive breast cancer and were followed for an average of 7 years after their diagnosis. Extensive interviews included data on whether or not they had taken multivitamin/mineral supplements at least once a week during the prior two weeks. About 38 percent of this population were using supplements and most were taking the supplements before their diagnosis. Comparison of the date on mortality and supplements showed that women who took the supplements had a 30 percent lower mortality rate than those who did not. This relationship remained even after taking into consideration such confounding variables as smoking status, education, race/ethnicity, weight, depression, alcohol use, physical activity, ager of breast cancer diagnosis, and diabetes.
