HIFU

New treatment aimed at halting prostate tumor growth

In 2018, approximately 324,000 men died from cancer in the United States. The combination of lung cancer, prostate cancer and colorectal cancer equated to half of those deaths. Large percentages of each of these cancers can be prevented or treated if caught early. Now, Purdue University scientists have created a new therapy option that may help halt tumor growth in certain cancers such as prostate, which is among the most common types of cancer in men. "We have designed a therapy that can help recruit immune cells to kill cancer and also help repair bone and tissues damaged by tumors," said Marxa Figueiredo, associate professor of basic medical sciences in Purdue's College of Veterinary Medicine, who helped lead the research team and is [...]

Researchers search for hereditary prostate cancer in genome study

Vanderbilt researchers have identified haplotypes, ancestral fragments of DNA, that are associated with hereditary prostate cancer (HPC) in a first-of-its-kind genomic study made possible by the study of prostate cancer patients with family histories of the disease. The researchers analyzed the Nashville Familial Prostate Cancer Study (NFPCS), in an investigation comparing men with prostate cancer, each from a separate family with a strong history of the disease, to screened men without a personal or family history of prostate cancer. They analyzed haplotypes at a location of chromosome 8 which has been tied to the origin of prostate and numerous additional cancers. The study, published March 23 in Nature Communications, explains roughly 9% of prostate cancer heritability. One mutation increased risk as much as 22-fold. [...]

California HIFU is the Right Choice for Prostate Cancer Treatment

For the past five years, Chris Lockheed’s PSA numbers had been going up. Then, when a biopsy revealed that he had two tumors on his prostate. Chris started doing research into what kind of options for treatment were available to him. When a radiation specialist in Rohnert Park told him about Dr. Michael Lazar and the HIFU procedure, he did more homework. Dr. Michael Lazar, 4 time board certified urologist, who has practiced in Santa Rosa for 36 years, investigated and became an early user of a new technology for treatment of prostate cancer called high intensity focused ultrasound, or HIFU. This exciting non-invasive technology uses ultrasound energy to create heat. This heat is precisely aimed at the cancerous portions of the gland to [...]

Understanding when to start prostate cancer screening

According to the latest research on prostate cancer prevention, it's important to be proactive and consult with a doctor to establish a prostate cancer screening schedule. The choice of screening options should make sense and take into consideration the personal risk factors and family history. Exactly when screening starts depends on a number of considerations, primarily based on statistics of prostate cancer and how it occurs among different population groups. Some important considerations include; Family history of prostate, ovarian, breast, colon, or pancreatic cancers among male and female relatives African ancestry Age Where a person lives Watch for These Signs More often than not, there are not fast and true warning signs for prostate cancer. That is because, an active prostate tumor usually [...]

Diabetes can affect prostate cancer prognosis

Men with type 2 diabetes are less likely to develop prostate cancer than patients without diabetes. However, the mortality rate is higher. Researchers were able to show that in the affected individuals the androgen receptor and the mitogenic forms of the insulin receptor were more strongly expressed. This could explain why patients with diabetes have a poorer prognosis for prostate cancer. Men with type 2 diabetes are less likely to develop prostate cancer than patients without diabetes.

Study examines prostate cancer treatment decisions

5-year study examines common prostate cancer treatment options (See new HIFU study results at bottom of this article.) A five-year follow-up study of more than 2,000 U.S. men who received prostate cancer treatment is creating a road map for future patients regarding long-term bowel, bladder and sexual function in order to clarify expectations and enable men to make informed choices about care. The CEASAR (Comparative Effectiveness Analysis of Surgery and Radiation for Localized Prostate Cancer) study, coordinated by Vanderbilt University Medical Center, is a multi-site research study conducting long-term followup on men who were diagnosed with localized prostate cancer between 2011 and 2012. The five-year results published in JAMA, with lead author Karen Hoffman, MD, MPH, from MD Anderson, provide evidence on outcomes with [...]

HIFU for prostate cancer shows excellent results in new study

Kia Michel, MD The 12th International Symposium on Focal Therapy and Imaging in Prostate and Kidney Cancer in Washington, D.C. featured Dr. Kia Michel, of Beverly Hills, Calif., who spoke on the outstanding data on focal HIFU outcomes for localized prostate cancer. Dr. Michel presented a poster on near-term HIFU outcomes based on his experience treating men with localized prostate cancer with the Sonablate. He presented that 78 men with prostate cancer underwent HIFU and were tracked post-treatment and re-biopsied at 12 months. He concluded that there was excellent disease control after HIFU ablation and most men were able to retain full urinary continence and erectile function levels equal to those pre-HIFU treatment. “I feel like it is important to report on [...]

Study reveals that being active has significant impact on prostate cancer risk

Prostate cancer is the number one cancer risk for men, as well as the No. 2 cancer killer behind lung cancer in the US, yet we still don't know all of its causes. The largest ever study to use genetics as a measurement for physical activity to look at its effect on prostate cancer, reveals that being more active reduces the risk of prostate cancer. Over 140,000 men were included in the study, of which, 80,000 had prostate cancer. This new study, published in the International Journal of Epidemiology in December, was led by the University of Bristol and co-funded by World Cancer Research Fund (WCRF) and Cancer Research UK (CRUK). It found that people with the variation in their DNA sequence that [...]

Understanding Prostate Screening & Treatment Options

For some types of cancer, screening can help find cancers at an early stage, when they are more likely to be easier to treat. According to the American Cancer Society, prostate cancer can often be found before symptoms arise by testing the amount of prostate-specific antigen (PSA) in a man’s blood. Another way to find prostate cancer is the digital rectal exam (DRE), in which the doctor puts a gloved, lubricated finger into the rectum to feel the prostate gland. If the results of either one of these tests are abnormal, further testing is often done to see if a man has cancer. If prostate cancer is found as a result of screening with the PSA test or DRE, it will probably be at [...]

Higher omega-3 levels does not increase prostate cancer risk

Omega-3 shown to protect against heart disease-related death, without increasing prostate cancer risk ---> Should you take omega-3 pills? Or try to have two to servings of omega-3 rich fish a week, as the American Heart Association recommends? It may seem a bit murky if you follow headlines about nutrition and health. That's why researchers at the Intermountain Healthcare Heart Institute continue to research the potential benefits and risks of this popular supplement, especially when it comes to prostate cancer risk and heart health. In one study, the Intermountain research team identified 87 patients who were part of the Intermountain INSPIRE Registry and had developed prostate cancer. These patients were also tested for plasma levels of docosahexaenoic acid (DHA) and eicosapentaenoic acid [...]
