Dr. Lazar Selected as Among Sonoma County’s Top Doctors

Santa Rosa urologist and prostate cancer expert Dr. Michael Lazar recognized in the field of Urology as one of the best physicians in Sonoma County. Every year, Sonoma Magazine’s Top Doctor survey polls Sonoma County doctors and medical specialists for physicians they most often recommend to a loved one. This year almost 500 professionals are noted in the September issue as “the crème de la crème” in more than 50 categories. Dr. Lazar was recognized by his medical peers in the field of urology. About Dr. Lazar “I am honored to be among the top doctors recommended by their peers again in this year’s survey,” says Dr. Lazar. “There are so many excellent physicians in Northern California and Sonoma County Magazine helps the highlight [...]

Dr. Lazar talks about HIFU for Prostate Cancer Awareness Month

Prostate cancer affects more then 3 million men every year, worldwide. Last year 1 in 9 men in the US were diagnosed with prostate cancer. Genes for disease can run in families. Men who have a relative with prostate cancer are twice as likely to develop the disease, while those with two or more relatives are nearly four times as likely to be diagnosed with prostate cancer themeselves. The risk is even higher when the affected family members were diagnosed before age 65. September is national Prostate Cancer Awareness Month. About 174,650 new cases of this type of cancer are reported each year, along with 31,620 deaths attributed to the disease annually. One in nine men will be diagnosed with prostate cancer during [...]

Random PSA screening misses some aggressive prostate cancers

Researchers point out that inviting men with no symptoms to a one-off PSA test for prostate cancer does not save lives. This from the largest ever prostate cancer trial conducted over 10 years by Cancer Research UK-funded scientists and published in the Journal of the American Medical Association (JAMA). Researchers at the Universities of Bristol and Oxford found that testing asymptomatic men with PSA detects some disease that would be unlikely to cause any harm but also misses some aggressive and lethal prostate cancers. This highlights the flaws of a single PSA test as a way to screen for prostate cancer, and shows the need to find more accurate ways to diagnose cancers that need to be treated. The CAP Trial, which spanned [...]

Optimizing prostate cancer treatment options with HIFU

Creating a customized plan optimized for a patient’s specific prostate needs is easier with Sonablate HIFU prostate ablation. “Did you know that prostate cancer can be treated without suffering the side effects of surgery and radiation? I am Dr. Michael Lazar, 4 time board certified urologist, who’s practiced in Santa Rosa for 36 years.  In 2007, I 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 kill the cancer while sparing the normal regions.  It is painless, bloodless and causes much less erectile dysfunction and almost no [...]

Researchers Suspect Connection Between Sugar and Prostate Cancer Risks

A study published by The BMJ today reports a possible association between higher consumption of sugary drinks and and an increased risk of cancer. While cautious interpretation is needed, the findings add to a growing body of evidence indicating that limiting sugary drink consumption, together with taxation and marketing restrictions, might contribute to a reduction in cancer cases. The consumption of sugary drinks has increased worldwide during the last few decades and is convincingly associated with the risk of obesity, which in turn is recognized as a strong risk factor for many cancers. But research on sugary drinks and the risk of cancer is still limited. A team of researchers based in France set out to assess the associations between the consumption of [...]

Protein identified that promotes aggressive prostate cancer

Study seeks to uncover new strategies to prevent or treat aggressive, late-stage prostate cancerProstate cancer represents a major health challenge and there is currently no effective treatment once it has advanced to the aggressive, metastatic stage. A new has revealed a key cellular mechanism that contributes to aggressive prostate cancer, and supporting a new clinical trial. The study was published in the journal Clinical Cancer Research.The research led by investigators at the Sidney Kimmel Cancer Center -- Jefferson Health (SKCC) and their collaborators at Memorial Sloan Kettering Cancer Center, the University of California, San Francisco, and Celgene Corporation, focused on an enzyme called DNA-PK (DNA-dependent protein kinase), a pivotal component of the cellular machinery that controls both DNA repair and influences gene expression. The [...]

Understanding how prostate cancer cells mimic bone may lead to new therapies

Prostate cancer often becomes lethal as it spreads to the bones, and the process behind this deadly feature could potentially be turned against it as a target for bone-targeting radiation and potential new therapies. In a study published online Tuesday in the journal PLOS ONE, Duke Cancer Institute researchers describe how prostate cancer cells develop the ability to mimic bone-forming cells called osteoblasts, enabling them to proliferate in the bone micro-environment. Attacking these cells with radium-233, a radioactive isotope that selectively targets cells in these bone metastases, has been shown to prolong patients' lives. But a better understanding of how radium works in the bone was needed. The mapping of this mimicking process could lead to a more effective use of radium-233 and to [...]

Researchers discover some tumors are more likely to be lethal than others

Most human cells have 23 pairs of chromosomes. Any deviation from this number can be fatal for cells, and several genetic disorders, such as Down syndrome, are caused by abnormal numbers of chromosomes. For decades, biologists have also known that cancer cells often have too few or too many copies of some chromosomes, a state known as aneuploidy. In a new study of prostate cancer, researchers have found that higher levels of aneuploidy lead to much greater lethality risk among patients. The findings suggest a possible way to more accurately predict patients' prognosis, and could be used to alert doctors which patients might need to be treated more aggressively, says Angelika Amon, the Kathleen and Curtis Marble Professor in Cancer Research in the Department [...]

When HIFU is the Right Treatment Option for Prostate Cancer

Is HIFU Prostate Cancer Treatment for You? Since many men are diagnosed with early-stage prostate cancer, often, they must choose between a risky surgical intervention, no treatment at all, or simply monitoring the disease. Among the many treatment options available HIFU falls somewhere in the middle. HIFU, which stands for high intensity focused ultrasound, offers a less invasive, lower risk method of eliminating the prostate in the body with fewer complications. With HIFU physicians are able to target and treat small amounts of tissue, minimizing damage to nerves around the prostate responsible for preserving potency. HIFU is an FDA approved precise and targeted therapy that reduces the risk of complications caused by surgery and radiation. HIFU uses ultrasound energy, or sound waves, to heat and [...]

HIFU for prostate cancer offers better outcomes for life

Using high energy ultrasound beams to destroy prostate cancer tumors shown to be as effective as surgery or radiotherapy, but with fewer side effects. A study, carried out at six hospitals across the UK, tracked 625 men with prostate cancer who received a type of treatment called high-intensity focused ultrasound (HIFU). The research is the largest ever study of HIFU treatment used to target prostate tumors. The treatment is similar to a 'lumpectomy' for other cancers -- where doctors remove only tumor cells, leaving as much healthy tissue as possible. The findings, from a number of institutions including Imperial College London and University College London, found that after five years the cancer survival rate from HIFU was 100 per cent. Approximately, 1 in 10 [...]
