For the first time, a research group at the Institute of Food Research led by Professor Richard Mithen has provided an explanation of how eating broccoli might reduce cancer risk based upon studies in men, as opposed to trying to extrapolate from animal models. Prostate cancer is the most common non-skin cancer for males in western countries. The research has provided an insight into why eating broccoli can help men stay healthy........ ]]> http://medicineworld.org/cancer/lead/6-2008/promising-cancer-drug-target-in-prostate-tumors.html http://medicineworld.org/cancer/lead/6-2008/promising-cancer-drug-target-in-prostate-tumors.html Wed, 02 Jul 2008 02:36:26 GMT Researchers at Dana-Farber Cancer Institute report they have blocked the development of prostate tumors in cancer-prone mice by knocking out a molecular unit they describe as a "powerhouse" that drives runaway cell growth. In an article that is being published recently as an advanced online publication by the journal Nature, the scientists say the growth-stimulating molecule called p110beta -- part of a cellular signaling network disrupted in several common cancers -- is a promising target for novel cancer therapies designed to shut it down. The report's lead authors are Shidong Jia, MD, PhD, Zhenning Liu, PhD, Sen Zhang PhD, and Pixu Liu, MD, PhD........ ]]> http://medicineworld.org/cancer/lead/5-2008/estrogen-helps-drive-prostate-cancer.html http://medicineworld.org/cancer/lead/5-2008/estrogen-helps-drive-prostate-cancer.html Wed, 02 Jul 2008 02:36:26 GMT Using a breakthrough technology, scientists led by a Weill Cornell Medical College scientist have pinpointed the hormone estrogen as a key player in about half of all prostate cancers. Estrogen-linked signaling helps drive a discrete and aggressive form of the disease caused by a chromosomal translocation, which in turn results in the fusion of two genes........ ]]> http://medicineworld.org/cancer/lead/5-2008/finasteride-in-preventing-prostate-cancer.html http://medicineworld.org/cancer/lead/5-2008/finasteride-in-preventing-prostate-cancer.html Wed, 02 Jul 2008 02:36:26 GMT A comprehensive re-evaluation of the largest prostate cancer prevention study ever completed produced new findings suggesting that men and their doctors should consider a more aggressive approach that includes finasteride to prevent the development of prostate cancer. A pathologic analysis of that same study sheds light on the significance of the cancers found in that study. Additionally, this study highlights the role of prostate specific antigen (PSA) scores in therapy decision-making. Scientists observed that even those men who have a low PSA screening value can have cancer that is difficult to cure........ ]]> http://medicineworld.org/cancer/lead/4-2008/predict-prostate-cancer-survival.html http://medicineworld.org/cancer/lead/4-2008/predict-prostate-cancer-survival.html Wed, 02 Jul 2008 02:36:26 GMT An Oregon Health and Science University Cancer Institute researcher has identified a protein that is a strong indicator of survival for men with advanced prostate cancer. The C-reactive protein, also known as CRP, is a special type of protein produced by the liver that is elevated in the presence of inflammation........ ]]> http://medicineworld.org/cancer/lead/4-2008/exercise-may-lead-to-faster-prostate-tumor-growth.html http://medicineworld.org/cancer/lead/4-2008/exercise-may-lead-to-faster-prostate-tumor-growth.html Wed, 02 Jul 2008 02:36:26 GMT Prostate tumors grew more quickly in mice who exercised than in those who did not, leading to speculation that exercise may increase blood flow to tumors, as per a new study by scientists in the Duke Comprehensive Cancer Center (DCCC) and the Duke Prostate Center. Our study showed that exercise led to significantly greater tumor growth than a more sedentary lifestyle did, in this mouse model, said Lee Jones, Ph.D., a researcher in the DCCC and senior investigator on this study. Our thought is that we may, in the future, be able to use this finding to design better drug delivery models to more effectively treat patients with prostate cancer, and those with other types of cancer as well........ ]]> http://medicineworld.org/cancer/lead/1-2008/links-between-prostate-cadmium-zinc.html http://medicineworld.org/cancer/lead/1-2008/links-between-prostate-cadmium-zinc.html Wed, 02 Jul 2008 02:36:26 GMT Cadmium exposure is a known risk factor for prostate cancer, and a new University of Rochester study suggests that zinc may offer protection against cadmium. In an article reported in the February 2008 journal, The Prostate, epidemiologist Edwin van Wijngaarden, Ph.D., reports that PSA levels were 22 percent higher among American men who had zinc levels below the median (less than 12.67 mg/daily) and cadmium levels above the median. (PSA is a protein produced by the cells of the prostate gland. The higher a mans PSA level, the more likely cancer is present.) ........ ]]> http://medicineworld.org/cancer/lead/1-2008/to-prevent-prostate-cancer.html http://medicineworld.org/cancer/lead/1-2008/to-prevent-prostate-cancer.html Wed, 02 Jul 2008 02:36:26 GMT Findings by UT Southwestern Medical Center scientists encourage men to weigh both the potential benefits and side effects of the drug finasteride before taking it to prevent prostate cancer. In todays online issue of Cancer, UT Southwestern doctors analyzed data gathered by the National Cancer Institutes Prostate Cancer Prevention Trial, or PCPT. The trial, which began in October 1993, was designed to test whether finasteride could prevent prostate cancer in men 55 years of age and older. It was stopped early in June 2003 when an analysis showed that finasteride reduced the risk of developing prostate cancer by 25 percent........ ]]> http://medicineworld.org/cancer/lead/11-2007/a-low-carb-diet-may-stunt-prostate-tumor-growth.html http://medicineworld.org/cancer/lead/11-2007/a-low-carb-diet-may-stunt-prostate-tumor-growth.html Wed, 02 Jul 2008 02:36:26 GMT A diet low in carbohydrates may help stunt the growth of prostate tumors, as per a new study led by Duke Prostate Center researchers. The study, in mice, suggests that a reduction in insulin production possibly caused by fewer carbohydrates may stall tumor growth. This study showed that cutting carbohydrates may slow tumor growth, at least in mice, said Stephen Freedland, M.D., a urologist at Duke University Medical Center and lead researcher on the study. If this is ultimately confirmed in human clinical trials, it has huge implications for prostate cancer treatment through something that all of us can control, our diets........ ]]> http://medicineworld.org/cancer/lead/10-2007/can-statins-make-radiation-more-effective.html http://medicineworld.org/cancer/lead/10-2007/can-statins-make-radiation-more-effective.html Wed, 02 Jul 2008 02:36:26 GMT Prostate cancer patients who receive high-dose radiation therapy and also take statin drugs usually used to lower cholesterol have a 10 percent higher chance of being cured of their cancer at 10 years after diagnosis (76 percent), in comparison to those who dont take these medications (66 percent), as per a research studypresented at a scientific session October 31, 2007, at the American Society for Therapeutic Radiology and Oncologys 49th Annual Meeting in Los Angeles........ ]]> http://medicineworld.org/cancer/lead/10-2007/effectively-cure-prostate-cancer.html http://medicineworld.org/cancer/lead/10-2007/effectively-cure-prostate-cancer.html Wed, 02 Jul 2008 02:36:26 GMT Radiation seed implants (brachytherapy) are just as effective at curing prostate cancer in younger men (aged 60 and younger) as they are in older men, as per a research studypresented at a scientific session on October 31, 2007, at the American Society for Therapeutic Radiology and Oncologys 49th Annual Meeting in Los Angeles........ ]]> http://medicineworld.org/cancer/lead/10-2007/walking-prevents-bone-loss-from-prostate-cancer.html http://medicineworld.org/cancer/lead/10-2007/walking-prevents-bone-loss-from-prostate-cancer.html Wed, 02 Jul 2008 02:36:26 GMT Exercise may reduce, and even reverse, bone loss caused by hormone and radiation therapies used in the therapy of localized prostate cancer, thereby decreasing the potential risk of bone fractures and improving quality of life for these men, as per a research studypresented on October 28, 2007, at the American Society for Therapeutic Radiology and Oncologys 49th Annual Meeting in Los Angeles........ ]]> http://medicineworld.org/cancer/lead/10-2007/guided-radiation-therapy-for-prostate-cancer.html http://medicineworld.org/cancer/lead/10-2007/guided-radiation-therapy-for-prostate-cancer.html Wed, 02 Jul 2008 02:36:26 GMT Oregon Health and Science University Cancer Institute scientists have observed that highly targeted radiation treatment for prostate cancer can ensure that the majority of persons with this tumor will not have any long-term rectal damage. A group of 231 study participants received a combination of intensity-modulated radiation and seed marker-based image-guided radiation therapies (IM-IGRT) for prostate cancer then were tracked for 1.4 years. Nearly 98 percent of these participants had no rectal damage, as per Todd Scarbrough, M.D., principal investigator, associate professor, radiation medicine, OHSU School of Medicine; and an OHSU Cancer Institute member. This combination allows for millimeter targeting accuracy of the tumor........ ]]> http://medicineworld.org/cancer/lead/10-2007/why-some-prostate-cancer-recurs-after-treatment.html http://medicineworld.org/cancer/lead/10-2007/why-some-prostate-cancer-recurs-after-treatment.html Wed, 02 Jul 2008 02:36:26 GMT Cancer scientists have long worked to understand why some prostate cancers recur after the use of therapies designed to stop the production of testosterone and other androgens that fuel cancer cell growth. New research has now detected that androgen-synthesizing proteins are present within cancer cells, which suggests that cancer cells may develop the capacity to produce their own androgens........ ]]> http://medicineworld.org/cancer/lead/10-2007/prostate-cancer-more-likely-to-return-in-blacks.html http://medicineworld.org/cancer/lead/10-2007/prostate-cancer-more-likely-to-return-in-blacks.html Wed, 02 Jul 2008 02:36:26 GMT African-American men are more likely to have their prostate cancer return after therapy, but their disease is no more aggressive when it does recur than that of their white counterparts, as per a research studyled by Duke Prostate Center researchers. Our study observed that African-American men have a slightly higher risk of what is known as PSA recurrence, which is a blood test that indicates the presence of cancer based on the levels of a certain biomarker known as prostate-specific antigen, said Stephen Freedland, M.D., a urologist at Duke and senior researcher on the study. We were encouraged, however, to see that their disease is not necessarily more aggressive than that of white men, once it has recurred........ ]]> http://medicineworld.org/cancer/lead/9-2007/does-black-men-and-prostate-cancer.html http://medicineworld.org/cancer/lead/9-2007/does-black-men-and-prostate-cancer.html Wed, 02 Jul 2008 02:36:26 GMT A University of Minnesota study of prostate cancer tumors from Caucasian and African-American men has shown no evidence that the cancer is more aggressive in black men. Lead investigator Akhouri Sinha, a professor of genetics, cell biology, and development and research scientist at the Minneapolis VA Medical Center, said the belief that black mens tumors are more aggressive is based on studies that failed to match patients properly and used only indirect means to measure tumor aggressiveness. The work will be published in Anticancer Research Sept. 21 (vol. 27, issue 5A, pp. 3135-3142)........ ]]>
