High PSA, but MRI is negative. Biopsy or Not?

Posted by lookin4answers @lookin4answers, Nov 22 3:42pm

I am 68. Watched my PSA gradually go from 4 (2020) to 9.05 (Nov 2025 test). MRI done in Nov 2024 showed no lesions, but enlarged prostate. Urologist wants me to get a biopsy. Stories about patients with similar PSA values (>9) having to endure multiple false negative biopsies is disconcerting. Should I demand to have another MRI done before the biopsy, or is the ultrasound good enough to find the lesions to sample during the biopsy?

Interested in more discussions like this? Go to the Prostate Cancer Support Group.

I was admitted to the hospital on 3/26 for renal failure caused by urine retention. They did a CT, MRI, and two ultrasounds. An enlarged prostate was mentioned in all reports but absolutely no mention of possible malignancy or apparent lesions.

Fast forward 3 weeks and urology pretty much insisted on biopsy based on PSA of 30+ and my continued inability to void completely without a catheter. Result - Gleason 9 (5+4) with 10 of 12 cores @ 100% involvement. Because the entire prostate was malignant, there was no contrasting image for them to see. It all looked the same. My conclusion based on my experience, if you want to be sure if its cancer or not, poke it and get a sample. Short of that, it's all a WAG.

Might redo the PSA. Hope your journey goes well.

Per my urologist a MRI looks for suspicious areas. It cannot determine if cancer. When my MRI/Fusion biopsies were done it revealed suspicious areas. My urologist gave it a 79% chance of being PC.

Having biopsies is much more accurate diagnosis of your PC and going to give you a Gleason Score. You cannot have a Decipher test without having a biopsy. Those biopsies are what is sent to Decipher for risk rating.

You mentioned pain and discomfort. There are two methods (offered by my Mayo urologist). One is transrectal usually done while you are awake and is through the rectum. It does come with higher risk of serious infection and also anxiety and stress of being awake.

The other is transperineally. It is usually done with anesthesia and you are not awake or aware of what is being done so there is no pain. I had my biopsies done transperineally as did not want the additional risk of infection nor did I want it done through my rectum and also wanted to be under anesthesia as have PTSD and anxiety/panic disorder so very important to me no to worry, stress out, feel pain or discomfort. I felt nothing after procedure was over. If someone had not told me it was over I would not even know it had been done.

There are many new tests out there can be done in addition to biopsies but a MRI is only going to show suspicious areas, tumors', things like that that does not give you a cancer diagnosis.

I had excellent Mayo urologist, excellent R/Os at both Mayo and UFHPTI, and excellent PCP. The information I passed on to you in this post comes from those medical experts.

I agree with your thinking. I posted a more complete summary of my story below which you can read for some more of the details of my particular case. Although I am extremely appreciative of the ExoDx test for pointing me toward what until then had been undetectable cancer, I do think there are better tests available now than the ExoDx. One of the other members on this forum is Jeff Marchi (@jeffmarc) and he has a summary chart that lists a number of the genomic type tests currently available with the accuracy that they are rated at - hopefully he will see this and post that chart for your reference. My recollection is that the best currently available test is the PSE test. So, my recommendation to you would be to ask your urologist to prescribe the PSE test and go on from there depending on that result and your urologists recommendations.

Here is that chart, but I don’t think it includes tests that Came out recently. I’ve included a second chart which has some newer tests

@handera : responding to your questions:
I had an elevated and fluctuating PSA for a number of years and was under the care of a center of excellence which included multiple MRI's and biopsies over 15 - 20 years, all of which were negative. I began to see a local urologist in 2023 and during my first visit we reviewed all of my previous history and the urologist did a DRE and a PSA. The DRE was normal - no abnormalities detected and the PSA was stable from the prior reading (basically unchanged for the prior year). At the end of that first appointment I asked about the newer genomic tests I had been reading about on this forum and others and asked if I could have one of those tests prescribed. I was given the ExoDx urine test and it showed a 36% probability of "treatable" prostate cancer. An MRI was done which was completely clear - no lesions or suspicious areas seen. The urologist recommended a saturation biopsy (24 cores) and that showed 2 of the 24 cores with a small amount (5% in each of the cores) of Gleason 4+5 cancer. Due to the high Gleason score, I decided to have an RALP and following that procedure the pathology report on the full prostate examined after removal resulted in the Gleason score being downgraded to 4+3 with tertiary 5. I had no further treatments and have my PSA checks every 3 months have all been < 0.1 (considered undetectable). I did not get a Decipher score.

My case is a bit unusual in that all indications other than the ExoDx seemed to indicate no cancer (normal DRE, stable PSA, MRI was clear) yet the saturation biopsy showed cancer. If your friend has an elevated ExoDx value, I would suggest proceeding with the MRI and on to a saturation biopsy regardless of what the MRI shows (but the MRI has value in case a lesion is seen as then that lesion can specifically be sampled using the Fusion biopsy process.)

Needless to say, my experience has made me a huge proponent of the genomic tests like ExoDx or PSE. My cancer would not have been detected as quickly as it was if I had not had the ExoDx test. Those tests are relatively inexpensive, and I think they should be used as a standard screening tool just as the PSA test is.

I’m surprised you liked the tests that tell you whether or not you probably have prostate cancer, but you are not having a decipher test which will tell you your chance of reoccurrence.

Wouldn’t it make sense to get that test so you know if biomarkers in your system are showing there is more of a problem then A PSA test will show you.

I went 3 1/2 years after my prostatectomy before my PSA started rising. It would’ve been nice if a decipher test has been available 16 years ago. It would’ve let me know I’ve had a higher chance of having reoccurrences, And I’ve had four.

@jeffmarc Very useful. Thanks.

I am in similar shoes. I’m 68 and have had a PSA number in the 5 range for probably 7-8 years. My regular doctor was never overly concerned because I have an enlarged prostate and have had for a long time. However over the last two years my PSA number went to 6.8 and then 8.6. I was referred to a urologist but before seeing him my regular doctor ordered an MRI. I had the MRI done on 9/12 and it was negative. However, upon seeing the urologist he strongly urged me to get a biopsy because of the percentage jumps of the PSA number. He said that because of those jumps I had a 20% chance of having cancer. I did the biopsy on 11/5. Twelve cores were taken and prostatic adenocarcinoma was found in six cores (3 cores were Gleason 3 + 3, which I understand are not usually concerning; 3 cores were Gleason 3 + 4). I now have another appt. With the urologist to consider what action to take. He told me over the phone that active surveillance was not something he would be comfortable in suggesting. I’m reading and talking to as many people as I can about their own personal journey and issues like side effects from the different treatments (surgery, radiation, etc). I am very fit, no issues other than the 2X normal size prostate and peeing twice a night fun. I’m looking hard at a prostatectomy for various reasons. Good luck and positive thoughts for all fighting this “fun”.

While you had 3 cores At 3+4 what was the percentage of carcinoma in those three cores and what was the percentage of four in those three cores?. If the percentages were very low 5% or 10% 4 then it is not an emergency, If it’s a high percentage, it could be something you need to treat right away.

My biopsy showed a 3+4 but when I had a prostatectomy, it was 4+3. Some people I know had 4+5 after a prostatectomy, but only 3+4 in the biopsy. They can only get about one percent of the prostate when they do a biopsy.

It should be interesting to hear what the urologist recommends. You should also see a radiation oncologist to see what other options you have If the urologist recommends surgery.

Were any of these things found in the biopsy intraductal, cribriform, Seminal vesicle invasion, EPE or ECE. (Extraprostatic extensions extra capsular extensions). Those can mean that the cancer is much more aggressive than it appears from the Gleason score.

You can get an MRI second opinion in the United States are about $250 if I remember correctly.

Here is a video about the company and procedure
https://ancan.org/
ProstatID is the procedure .

Founder and Developer, Randall Jones, PhD, explains the technology and its uses in the video.

@jeffmarc I've thought a lot about this and am getting further convinced that before I schedule a biopsy, I will insist on the EpiSwitch PSE test, then if PSE says cancer is present, I'll get another MRI to find lesions, and then schedule the biopsy so they know where to target the needle.

Thanks to all here for providing me with some insight and direction.
