Better Prostate Biopsy – new study

New Study from JAMA shows a better prostate biopsy is gaining momentum

Takeaway First

JAMA study suggests men undergoing a prostate biopsy to check for cancer should look for a targeted MR/ultrasound fusion biopsy (or, more simply, a “targeted biopsy”) which can find deadly cancer more accurately than a standard ultrasound-guided prostate biopsy (more simply, a “standard biopsy”)

Study Details

  • Participants were 1003 men undergoing both targeted and standard biopsy concurrently from 2007 through 2014 at the National Cancer Institute in the United States.
  • The primary goal was to compare targeted and standard biopsy approaches for detection of high-risk prostate cancer (Gleason 7 (4+3) or higher)
  • The secondary goal focused on detection of low-risk prostate cancer (Gleason score 3 + 3 or Gleason 7 – (3 + 4)] and the biopsies’ ability to predict the risk of disease after prostate removal and observed by a pathologist.
  • Targeted biopsies diagnosed 30% more high-risk cancers than standard biopsies (Siddiqui et al., 2015).

My Take On Prostate Biospies

At this point, the notion that you can get a better prostate biopsy with the MR/Ultrasound technology is a no brainer. Men who suspect they have prostate cancer should only be looking for cancer that could kill them. (That’s the more important kind.) For all others, say a Gleason score of six or less, we should “let sleeping dogs lie” as the saying goes.

The rub is that it is difficult to find physicians who perform targeted biopsies in the U.S or in the rest of the world. Community physicians are particularly unlikely to perform this newer form of test because there is a relatively steep learning curve, not to mention higher costs, associated with MR/US fusion biopsies. Also, targeted biopsies are a team effort among urologist, radiologist and pathologist. As it pertains to radiologists, the training in performing MRIs and interpreting the images requires a specialized skill specific to prostate doctors. In other words, radiologist who typically looks for cancerous lesions of the breast may be underqualified to find lesions of the prostate.

What Should You Do if you need a Prostate Biospy?

If you are able to travel and get the right type of prostate biopsy (MR/US guided prostate biopsy), then do so. A regular ultrasound prostate biopsy is, frankly, antiquated right now and may either miss potentially deadly prostate cancer cells (a false negative) or find insignificant non-deadly cancer cell that are not worth worrying about. A cancer diagnosis of indolent cells, while still better than deadly cells, still provokes anxiety. And an anxious life is no way to live.

Current sites that do targeted MR/US guided prostate biopsy include:

NYU Smilow Comprehensive Prostate Cancer Center, New York – CLICK HERE

National Cancer Institute department of Urology, Maryland – CLICK HERE

UCLA Urology, Los Angeles – CLICK HERE

Dr. Steve Scionti, Sarasota, Florida – CLICK HERE

This list is incomplete as I am still learning about groups performing MR/US fusion prostate biopsies.

If you are a physician reading this and you perform MR/US fusion prostate biopsy please let us know down at the comment section.

  • Dr. Geo,

    Please add Dr. Emilia Ripoll at Choices (www.choicespc.net) in Health in Boulder, Colorado to the list of urologists/urologic oncologists who are using MRI fusion prostate biopsies.

    Cheers,

    Mark

        Hi Geo,

        Two weeks ago I had an MRI of the prostate at Park Ave. Radiologists. Last week Dr. David Samadi did a MRI guided biopsy. in his office. The anticipation was much worse than the procedure which took only about fifteen minutes and was not at all painful. I saw Dr. Samadi yesterday and all my markers were clean. What a relief. I told Dr. Samadi that I had seen you. He wants to recruit you to Lennox Hill. Hope you get a raise.

        • Ha. Thanks Michael. Dr.Samadi is very kind. I’m glad your biopsy outcome went well.

    Dr Geo,

    I’d like to mention Dr. Stepehen Scionti. He performs the target biopsy

    • Dr. Scionti I know well as we worked together for a while here at NYU. He is an amazing diagnostician and focal therapy expert. Thanks, Dan.

  • Good morning Dr. Geo
    Dr. Ehdaie is running a study at Sloan on MRI guided biopsies. I am his patient and I am going for the MRI next week. I can’t say anything more about him at this time as I’ve only seen him once. The biggest issue with the guided biopsy is they still take samples from all regions of the prostate besides the suspicious ones as there isn’t enough data to limit it so my biopsy will be 15 samples.

    • Great point, Scott. Targeted biopsy are better, no doubt, but they are still learning what methods works best.

    This week had I was a patient at Desert Medical Imaging for M/P MRI guided forcal laser ablation of a ,7×1.0x1.3cm malignant tumor (Gleason 7, 3plus4) in my prostate, which had been identified with a targeted biopsy several months ago..The proceedure went very well… with no after effects at all .This year I recieve follow up exams….Really impress with this conservative treatment….need to catch these things early……find an office that will do the multi parametric MRI..
