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 [...]

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 [...]

Benefits of HIFU technology revealed in 3 studies and reports

Three articles have appeared in press since June 2018 based on clinical trials undertaken in the U.K., that highlight the medium to long-term durability of Sonablate treatments in the control of prostate cancer when used in the partial gland ablation setting.1,2,3  Across the three articles and a total of more than 1,800 men, salvage free survival (no need for a whole gland or systemic treatment) was greater than 90% out as far as 60 months.  This excellent disease control was accompanied by a pad-free incontinence rate of greater than 98% and maintenance of erectile function in more than 80% of men. An additional article based on Canadian experience produced roughly similar results. 14 Dr. Mark Carol, CEO of SonaCare Medical writes,“While few will [...]

Immunotherapy may add years for prostate cancer patients

Some men with advanced prostate cancer who have exhausted all other treatment options could live for two years or more on immunotherapy, a major clinical trial has shown. Researchers found that a small proportion of men were 'super responders' and were alive and well even after the trial had ended despite having had a very poor prognosis before treatment. The study found that one in 20 men with end-stage prostate cancer responded to the immunotherapy pembrolizumab -- but although the number who benefited was small, these patients sometimes gained years of extra life. The most dramatic responses came in patients whose tumors had mutations in genes involved in repairing DNA, and the researchers are investigating whether this group might especially benefit from immunotherapy. [...]

A Typical HIFU Procedure Day

Wake up, get ready, and head to the treatment facility. Patients will need to complete their bowel prep per their MD’s instruction. This is comparable to a prostate biopsy bowel prep. 6 am – 7 am | Arrive at treatment facility, be greeted by staff, and enter procedure preparation area. Patients will typically be asked to arrive at the treatment facility at least an hour before the procedure. 7 am – 10 am | Sonablate HIFU Procedure A typical HIFU procedure lasts between 2-4 hours (depending on the size of the prostate) and is either done under general anesthesia or an epidural and IV sedation. During the procedure a catheter will be put in place to help with urination, and will stay in [...]

Researchers aim for a paradigm shift in prostate cancer diagnosis

In combination with the current prostate specific antigen (PSA) test, the new test could help men avoid unnecessary and invasive biopsies, over-diagnosis and over-treatment. Prostate cancer is the most common cancer in Western men, with 1.3 million new cases being diagnosed each year worldwide. It is currently detected using a blood test that measures PSA levels. Although it provides early diagnosis, the PSA blood test has a low specificity (high false positives) with about 75 per cent of all PSA positive results ending up with negative biopsies that do not find cancer. When a high PSA level in the blood is detected, the patient undergoes a tissue biopsy of the prostate gland, which is invasive and carries a significant risk of bleeding and [...]

Prostate cancer risks may be lowered by mushroom consumption

A new study published in the International Journal of Cancer found an inverse relationship between mushroom consumption and the development of prostate cancer among middle-aged and elderly Japanese men, suggesting that regular mushroom intake might help to prevent prostate cancer. A total of 36,499 men, aged 40 to 79 years who participated in the Miyagi Cohort Study in 1990 and in the Ohsaki Cohort Study in 1994 were followed for a median of 13.2 years. During follow-up, 3.3% of participants developed prostate cancer. Compared with mushroom consumption of less than once per week, consumption once or twice a week was associated with an 8% lower risk of prostate cancer and consumption three or more times per week was associated with a 17% lower [...]
