I stumbled across this video on my YouTube feed and found it to be a great overview of many of the trials that are behind the advances in advanced prostate cancer treatment. The video is apparently part of a larger training course for doctors, so it’s not geared toward patients. Even so, I found it informative and (mostly) understandable.
One thing that I found interesting was that there’s an apparent shift away from the use of the word “castration” in describing the state of the disease and treatment options.
The purpose of this was really to ensure that we were trying to be thoughtful around our patients’ feelings around use of the word “castration” and trying to eliminate that from the terminology.
Instead of describing it as “non-metastatic castrate sensitive prostate cancer (nmCSPC)” it’s now called “androgen pathway modulation sensitive (APMS)” or “androgen pathway modulation naïve (APMN).” Once the cancer becomes resistant, it will be called “androgen pathway modulation resistant (APMR).”
To me, it seems as though they want to sugarcoat the hormone therapy experience with these name changes, and the patient may not grasp the full gravity of what’s about to happen to him when he starts this treatment. I’d definitely understand “castration” before understanding “androgen pathway modulation sensitive.” To be fair, it would be interesting to see how many men turn down hormone therapy because they hear the word “castration.” Maybe that’s the driving force behind the name change.
Because Dr. Rettig works with veteran patients at the VA Los Angeles, it was helpful to me to hear some of his insights working with that group.
I overachieved on this post. Normally, reporting PSA results would be quite simple and short. Not this time. The act of writing helps me organize my research and rationalize treatment decisions. Thanks for your indulgence!
I went for my PSA test this morning, 1 September, and it was 3.32 ng/mL, up from 2.65 ng/mL back in May.
I expected my PSA to go up, and I guessed it would be around 3.0 ng/mL, so the amount it went up was a bit of a surprise. It’s closing in on my PSA level at initial diagnosis, 5.0 ng/mL.
PSA Doubling Time
Seeing as both the VA and UCSD medical oncologists (MO) stressed the importance of using PSA doubling time (PSADT) to guide treatment decisions during my meetings with them in June, I really wanted to try to nail down how it should be calculated.
The Memorial Sloan-Kettering PSADT Calculator is a great tool that I’ve been using, but it doesn’t provide any guidance on how many data points should be used over what period of time. I finally found some definitive guidance:
PSA values need not be consecutively rising and all values obtained over a maximum period of 12 months should be included in the calculation. The maximum period of the past 12 months is recommended to reflect the patient’s current disease activity, since in some men PSADT may change over time. Minimum requirements for the calculation are 3 PSA values obtained over 3 months with a minimum of 4 weeks between measurements.1
You can see that I’m sitting right around that nine-month PSADT point that’s the suggested trigger for action. I’m going to keep my mouth shut and ask my MO to calculate the PSADT and see what number they come up with.
Obviously, I’m concerned, but not panicked by this jump in my PSA. I’ll email the MO to see if we should stick to the current plan of having a CT scan on 23 November, or move it to an earlier date. Or to have another PSMA PET scan. In my mind, I’d like to have at least one more scan to try and see if we can determine what we’re dealing with before leaping into combination hormone therapy.
Combination Therapy
The MO’s were really encouraging action if my PSADT was nine months or less because, with faster doubling times, there is high risk of metastasis and prostate cancer-specific mortality. The action that they’re recommending is intermittent combination therapy using androgen deprivation therapy (ADT) plus an androgen receptor pathway inhibitor (ARPI). The specific drugs they’re recommending are Eligard® (leuprolide acetate) (ADT) and Xtandi® (enzalutamide) (ARPI). The Eligard® would stop the production of testosterone, and the Xtandi® would block the cancer cells from absorbing testosterone.
The reason that the MOs want to use the combination therapy is because of the results that were shown in the EMBARK trial. Using Eligard® and Xtandi® together had 87.3% of patients in the trial reach the five-year point metastasis-free. Using just Eligard® alone—the old standard of care—just 71.4% of patients were metastasis-free at five years. The combination therapy won’t prevent progression to metastasis; it just slows it down. This short (2 min.) video from the New England Journal of Medicine gives a good overview:
The combination therapy would be given intermittently, with nine months on the medication and, if my PSA drops to a certain level (usually below 0.2 ng/mL) and stays there, there wouldn’t be a need to restart the combination therapy until there’s a rise in my PSA.
The one thing that I couldn’t find or confirm in my research was if there was a specific PSA level where, if you exceed it, this combination therapy should be started. The UCSD MO seemed okay with waiting until it was as high as 5 to 10 ng/mL if the PSADT didn’t indicate high risk.
Xtandi® (enzalutamide) is just one of several drugs known as Androgen Receptor Pathway Inhibitors (ARPIs). Two others that are commonly used include ERLEADA® (apalutamide) and NUBEQA® (darolutamide). Each has its own similar, but slightly different side effects.
Side Effects / Adverse Events
Messing around with your hormones can have substantial and sometimes debilitating side effects and, when using combination therapy, they can be additive. The National Cancer Institute has defined five grades of adverse events based on their severity:
Grade
Impact
Grade 1
Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated.
Grade 2
Moderate; minimal, local or noninvasive intervention indicated; limiting instrumental ADL or mild/moderate impact on age appropriate normal daily activity (pediatric)*.
Grade 3
Severe or medically significant but not immediately life threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care ADL or severe impact on age appropriate normal daily activity (pediatric)**
Activities of Daily Living (ADL): *Instrumental ADL refers to preparing meals, shopping for groceries or clothes, using the telephone, managing money, etc. **Self-care ADL refers to bathing, dressing and undressing, feeding self, using the toilet, taking medications.
Clearly, a patient would want to steer clear of any Grade 3 or 4 side effects if possible. When you look at the grades of adverse events in the summaries of each of the drugs below, you’ll see that the percentages of patients experiencing an adverse event at all grade levels can be quite high in some cases. Bottom line: ADT + ARPI will adversely impact you and your quality of life in some shape or form. It’s just a matter of degrees.
Some of the possible, more severe side effects include:
Heart disease, stroke, or mini-stroke
Fractures and falls
Lung problems
Seizures
Severe skin reactions
And you can see what percent of the time that patients experienced some of these side effects by adverse event grade in section 6.1 of the prescribing information HERE or in these tables HERE. Some of the Grade 3 or 4 adverse events occurred as much as 8% of the time.
Some of the possible, more severe side effects include:
Heart Disease
Seizure
And you can see what percent of the time that patients experienced some of these side effects by adverse event grade in section 6.1 of the prescribing information HERE. Some of the Grade 3 or 4 adverse events occurred as much as 4% of the time.
Some of the possible, more severe side effects include:
Seizure
Posterior Reversible Encephalopathy Syndrome (PRES) (Involves the brain with seizure or quickly worsening symptoms such as headache, decreased alertness, confusion, reduced eyesight, blurred vision or other visual problems)
Allergic reactions
Heart disease
Falls and bone fractures
Swallowing problems or choking (because of the size of the pills)
And you can see what percent of the time that patients experienced some of these side effects by adverse event grade in section 6.1 of the prescribing information HERE. Some of the Grade 3 or 4 adverse events occurred as much as 9% of the time.
Some of the possible, more severe side effects include:
Heart attack
Elevated blood sugar and increased risk of developing diabetes
Convulsions
And you can see what percent of the time that patients experienced some of these side effects by adverse event grade in section 6.1 of the prescribing information HERE.
Anecdotal Side Effect Experiences
One of the side effects that isn’t specifically mentioned above was cognitive decline. In a study, it was shown:
Patients with advanced prostate cancer treated with enzalutamide (Xtandi) had a significantly greater decline in cognitive function compared with those who received darolutamide (Nubeqa), according to results from a phase II trial.
Median cognitive change in the maximally changed cognitive domain (MCCD) from baseline to 24 weeks was -15.8% for those receiving darolutamide versus -36.1% for those receiving enzalutamide (P=0.009), reported Alicia Morgans, MD, MPH, of the Dana-Farber Cancer Institute and Harvard Medical School in Boston.2
I’m a member of an online support forum for advanced prostate cancer on HealthUnlocked, and one of the common themes of other patients who have been on Xtandi® (enzalutamide) is significant “brain fog.” Many had such severe side effects that they stopped taking Xtandi® (enzalutamide), with one patient calling it “poison.”
Now, I take what’s said in forums like that with more than a grain of salt. There’s definitely some selection bias going on—patients who are having difficulties with their treatments are more likely to talk about them in a forum than those whose treatments are going well. We just don’t know how many are out there who have minimal side effects and tolerate the treatments well.
Drug Interactions
I surprise medical professionals when they ask me to list my current prescriptions because I only have one: amlodipine to manage hypertension. I checked on Drugs.com to see if any of the four drugs above will interact with the amlodipine:
Because a well-known side effect of ADT is osteoporosis/bone density loss, patients are usually given calcium and vitamin D supplements to slow or minimize the loss. Interactions with calcium and vitamin D:
Clearly, we’re going to have to have a discussion about the amlodipine before starting anything because it has made a difference. My systolic number has dropped by 33 points and my diastolic number has dropped by 24 points. Part of that may be the amlodipine, and part may be the fact that I’ve lost 44 lbs. / 20 kg since starting the amlodipine (or both).
Timing of Starting ADT + ARPI Therapy
You may recall back in April, I shared an AnCan Foundation video of a seminar featuring Dr. Ravi Madan and Dr. Melissa Abel from the National Cancer Institute (NCI). In it, they raise the notion that with new PSMA PET scans, we may be moving too quickly to treat biochemically recurrent prostate cancer and may be overtreating patients, subjecting them to the side effects of ADT either unnecessarily or prematurely.
From the video notes:
Dr. Paul Schellhammer, said in the meeting, ‘it’s like listening 15 years ago to the folks who began to promote active surveillance (in first line treatment).” Dr. Madan and Dr. Abel have collected solid data from around 150 patients that suggests men with slow PSA doubling times can “play the long game” as Dr. Ravi calls it, and defer active treatment when their disease recurs.
Just like the concept of active surveillance, this approach does seem counterintuitive. It’s a novel take that probably isn’t that widely accepted yet, but when you watch the video and look at the data, it makes sense. They’re not saying that treatment won’t be required at some point; they’re just making a case for delaying the treatment in order to maintain quality of life, especially if nothing is showing up on scans.
One difference in their approach is that they define a high risk PSA doubling time to be in the three to six month range, instead of the widely accepted less than nine month range.
I have to admit that the NCI doctors have me thinking more and more about the timing of starting this combination therapy because, let’s face it, no one leaps at the opportunity to go on hormone therapy given the “fun” side effects that it brings.
When I was on Eligard® (leuprolide acetate) during my salvage radiation therapy, I tolerated it probably better than most men do. I had mild to moderate fatigue; was more emotional; lost most of my libido; but avoided hot flashes, weight gain, and some of the other common side effects. The unknown is adding the ARPI to the mix.
Of the three ARPI agents available, Xtandi® (enzalutamide) seems to be the worst when it comes to side effects and patient experiences relayed in the prostate cancer forum. Of course, that’s the ARPI that the VA apparently uses in its treatment. NUBEQA® (darolutamide) seems to have the similar results when it comes to delaying metastasis with fewer side effects,3 so you can bet I’ll be having a conversation about this option with the medical oncologist when the time comes.
If you were to ask me right now what I plan on doing, my short answer is, “I don’t know.”
On the one hand, my PSADT hovering right around the action point and has been for some time now. Is that alone reason to act?
In his video, Dr. Madan basically concluded that, if your PSADT is >6 months and you don’t have any cancer showing up on scans, you can just continue to monitor the PSA without starting the hormone therapy—in other words, active surveillance for biochemical recurrence. As I recall, he observed patients for several years with increasing PSAs and consistently negative scans. Do I roll the dice based on his research and conclusions?
That’s one of the reasons that I want to have at least one more scan before committing one way or the other.
Once again, I’m in yet another decision dilemma with the science pulling in different directions.
Depending on what the VA MO says, I may also solicit the input of the UCSD MO one more time and go from there. I’m also open to thoughts and experiences from you.
More to come, that’s for sure.
Be well!

Before getting into the conversation with the urologist, I went for my bone density scan last week. The results? I have bones. They’re dense (i.e., normal). Now we have a baseline for future reference for if and when I start down the hormone therapy path.
Yesterday’s meeting with the urologist was unusually animated, if not bordering on contentious. The appointment was late in the afternoon (around 3:45 p.m. when she arrived), so perhaps she had had a crappy day and was ready for it to end.
I tried explaining my conversations with both oncologists, and she kept interrupting, sometimes with questions that made it seem that she wasn’t paying much attention. (She was on her computer reviewing my file as I talked; usually she’ll have reviewed the file before even walking into the exam room.)
At one point she said, “You have three cooks in the kitchen and should probably stick with one,” referring to the fact that I had two oncologists and her trying to manage my case.
When it comes to treatment, she’s still of the opinion to wait until metastasis to start hormone therapy, mainly because of the associated side effects and possible earlier resistance to the therapy. I mentioned that both oncologists recommended intermittent hormone therapy, and she seemed puzzled by that for some unknown reason.
I mentioned that the plan was for me to have another PSA test in the first week of September and, if warranted, a CT scan and bone scan in December. She seemed indifferent and offered no comment one way or the other.
By the end of the appointment, it was pretty clear that she was of the mindset that there’s little that she as a urologist can do at this point in my case management, and that the ball belongs squarely in the court of the oncologists. I agree. She did say, though, that if I start to have urinary symptoms that may be from the radiation or surgery (e.g., strictures, worsening incontinence), to come back to Urology for investigation and possible treatment. We did not set up a follow-up appointment for Urology.
Back in April, the oncologist suggested they take the lead on my case and, after yesterday’s appointment with the urologist, it’s clear that that’s what needs to happen.
I’ve got the PSA test on my calendar on 2 September. We’ll get the results, calculate PSA doubling time, and consult with the oncologists to determine the next steps based on the results.
If my PSA shoots up again like it did between December and March, reducing my PSA DT, I might be more inclined to act. But if it continues on a flatter trend like it did between March and May, I’d be inclined to kick the can down the road another three months.
So I’ll continue to live life in three-month increments until the results tell me it’s time to do something. Good thing I have a lot of hurry-up-and-wait experience from the Navy. 🙂
I’m not sure how I managed it, but I picked up a nasty head cold after yesterday’s meeting with the oncologist. Perhaps it was from being at the hospital two days in a row, or from me riding our commuter-packed light rail system to get to the hospital (stops right at the hospital) that did me in, but whatever bug I caught kicked in around 5 p.m. yesterday.
Around 7 p.m. tonight, I was nursing the head cold, watching the ballgame on television when my phone rang, and I was surprised to see it was a call from the VA.
It was the head of the urology department inquiring about continuing my pelvic floor therapy at a community provider. (You may recall that I started that back in December, and the original end date of the therapy was 2 April.) I told her that the therapist and I agreed that I had plateaued and didn’t see a need for me to continue.
Not one to miss an opportunity, I mentioned me meeting with the oncologists yesterday and asked her for her take on whether starting hormone therapy would be appropriate. I also mentioned the negative scan results. She was more of the mindset of waiting until there was evidence of spread, and she said, “I wouldn’t chase numbers,” when I mentioned my current PSA level.
She noted that I had the follow-up with the oncologists on 2 June and a follow-up with urology on 23 June, and said we can review things then.
Once again, the “experts” offer differing approaches, and it’s up to us, the patient, to pick and choose what’s best. After 15 years, it’s not a surprise, but it still is frustrating at times. MO Jr. did mention that it may be appropriate to convene the “Tumor Board” to get all the key players in the same room and review the case for the best course of action.
At this point, I’m inclined to get the PSA test at the end of May and, with that new information, try to push to get everyone in the same room for a discussion of next steps forward. Or at least have them convene the Tumor Board without me.
In the meantime, I’m just going to curl up in a ball and try to get the worst of this head cold behind me before the weekend.
As I was driving to the barber to get my hair cut (both of them), my phone rang. Normally, I avoid phone conversations when I’m driving—even the hands-free, Bluetooth variety—but when the Caller ID popped up on the infotainment screen as being the VA Medical Center, I answered because I thought it might be the Oncology scheduler calling to set up an appointment.
Instead, the call was from the urologist I met on Tuesday to talk about his research and efforts to pursue an Axumin scan. (I sent an email to him yesterday saying that I did a little legwork for him and learned that UCSD still does Axumin PET scans in case the VA didn’t.)
In a nutshell, he contacted the VA nuclear medicine department and, according to him, they were very elusive with him in saying whether they even had the ability to do the scan at the VA and, even if they did, if they would do it considering the PSMA PET scans have replaced it in their minds.
Then the doctor again put his faith in the PSMA PET scan and thought that the Axumin scan wouldn’t provide any useful information. He also mentioned that he looked at the 10% of patients not having PSMA protein and said, from his quick research, it seemed to only been identified in a single study. Unfortunately, that was said at a time when I was more focused on driving than listening, and I’m sure I didn’t fully understand what he was trying to convey.
I was finally able to safely park and give 100% of my attention to the conversation, and he said one other thing that puzzled me. He seemed confident that, because my PSA was rising, I did, in fact, have the PSMA protein. I’m not sure that I agree with that and need to do some digging.
We did talk about having a Pylarify PSMA PET scan which uses a different tracer than the 68-Ga-PSMA-11 PET scans. He thought that that could be a possibility, but wasn’t sure that the VA offered it yet. He knew it had been FDA-approved, but thought that the VA hadn’t developed the protocols for its use yet. I mentioned that when I spoke with UCSD yesterday, they said they had the ability to do Pylarify scans, too.
I asked him about how I might get a referral from him/the VA for me to get the scan on my own, and he thought that there may be a number of bureaucratic hoops to jump through to make that happen, including determining if something was “medically necessary.” He wasn’t exactly sure of the process, especially if I was going to use my own insurance (Medicare).
I just wanted him to confirm that, in his view, there was value in getting a scan to learn the location of the cancer and what it’s doing. He agreed.
I told him that my goal was to find the cancer and, if there were one or two lesions, to do spot radiation to knock them down if they’re in a suitable zapping location. That may help delay the start of ADT. (Or not. I’m not sure if they put patients on ADT when going after oligometastatic lesions.)
Finally, he did ask if I had been scheduled with the oncologist yet, and I have not. He was interested in hearing what they had to say about scans.
Needless to say, the waters have been muddied and I’m a little less confident that I know what’s going to happen next.
I’ll send him an email in the morning recapping our conversation, with an emphasis on his agreement that having a scan at this point is important. Translation: Medical necessity. I’ll also let him know that I’m open to trying any scan that he thinks will work.
I may also ask him to explain again why he is convinced that I have the PSMA protein and why he’s skeptical of the 10% number.
I’ll also try to connect with the oncology schedulers and get that appointment on the books.
I may also look at what it takes to get myself in as a patient at UCSD through either their urology or medical oncology departments. Because UCSD did my salvage radiation therapy in 2022, I may still be in their system, so it may be less difficult than starting from scratch. I’ll have to figure out how to share my VA health records with UCSD if needed.
Those of us of a certain age may remember the “Stump the Band” segment on the Johnny Carson show, where audience members asked the band to play some obscure song. Well, today was my turn at “Stump the Urologist.”
It was a very productive meeting that lasted nearly 40 minutes which was unusual. I came equipped with hard copies of my PSA chart, the MSKCC PSA doubling time (PSA-DT) calculator results, and my list of questions. He was impressed and really pleased with the chart in particular.
We started talking about how my four PSMA PET scans were all inconclusive, and I steered the conversation to whether I might be one of the 10% for whom PSMA PET scans don’t work. He seemed to be a bit skeptical at first, but he also said it was a possibility.
Given that my PSA increased substantially and my PSA-DT was decreasing, I wondered if it would be better to jump into ADT sooner or if there’s still value in trying to find the cancer’s location with imaging. He was of the opinion to continue to try to find it before starting ADT.
I had a series of questions that really dealt specifically with ADT, and he said it was a bit premature to think about those and that they would be better answered by a medical oncologist. I knew that I was jumping the gun with some of them, but I thought I’d ask anyway. During that part of the conversation, I did mention that I tolerated the ADT probably better than most when I had it for my salvage radiation therapy, but that I wasn’t eager to jump into it earlier than necessary.
After that, he took control of the conversation and asked me about my status when it came to sexual function and incontinence, and offered up options to deal with both if I was interested.
Then we returned to the topic of next steps, and that’s where I played “Stump the Urologist.” (Who, by the way, was a full-blown internist and not a resident.) He grabbed my PSA chart and excused himself for a few minutes as he went off to consult with the department head.
When he returned, I was a bit surprised when he put his faith in the results of the PSMA PET scan, saying it has the best sensitivity and the best specificity of any scan out there. He said that they had moved away from the Axumin scans because they were the old technology.
I politely pushed back, reminding him that a PSMA PET scan should have had an 80% – 90% chance of finding my cancer at my PSA level if I had the PSMA protein for the 68-Gallium tracer to lock onto. But if I don’t have that PSMA protein, the sensitivity and specificity of the scan won’t matter because nothing will ever light up. He really couldn’t argue against that.
I went back to the topic of ADT and mentioned that I met with a medical oncologist (MO) two years ago, and received conflicting opinions on when to start ADT. The MO said she would start my ADT when my PSA hit 2.0 ng/mL (a urologist said she wouldn’t start it until there was evidence of metastasis). Today’s urologist said he looks for one of three “triggers” to begin ADT: PSA > 10.0 ng/mL 😲; PSA-DT less than six months; or evidence of metastasis.
I also mentioned that the VA MO that I saw two years ago was a general oncologist and not someone who specialized in genitourinary cancers and, as helpful as she was, she had to consult with a UCSD MO who specifically deals with prostate cancer. I sowed the seed of eliminating the VA MO as a middleman if they have to consistently consult the UCSD doctor (who is highly regarded in the field), and suggested that I could just see him directly. I’m not sure if that will take root.
Finally, I did ask a very basic question given how elusive this has been: Is this even cancer? He said that, if I hadn’t had a prostatectomy, that there might be other explanations for the rising PSA. But he was confident that we are, in fact, dealing with cancer.
That led to a follow-up question of: Is it metastatic? Based on the information we have, he said it’s not. He seemed to squirm a bit when I asked about it being micro-metastatic, because, in his mind, that wasn’t very well-defined.
Before mapping out a plan, I have to admit that my ego puffed up a tad when he said, “You’re the best educated patient I’ve seen in weeks.” He also admitted that my case was a bit puzzling to them and not something they routinely see.
We agreed on three actions:
The doctor is going to explore how and where I can get an Axumin scan, and if the VA will authorize it if I have to go outside the VA. That may take a day or two to get an answer. I mentioned that I’d be willing to use Medicare and go out on my own if necessary.
He is doing a referral to get me seen by the VA oncology team to get them familiar with my case. I suspect it will take a few days to hear from the scheduler.
We do another PSA test in June and meet to see where we’re at.
All in all, this was a good meeting with a robust discussion about my case that has all of us scratching our heads as to what’s going on and what to do next. Frustrating? Yes, to a degree. But, as we discussed during the meeting, nothing is black-and-white in the world of prostate cancer.
More to come.
Be well!
For my readers outside the U.S. who may not be familiar with Johnny Carson, I was going to link a random video clip of his “Stump the Band” segment above and, when I searched YouTube, this—of all clips—was the one that popped up first. I think you’ll see the related humor in it once you watch it. 😂

My fourth PSMA PET scan is in the books. If I keep this up, I should join a PSMA PET scan loyalty club—have five scans and get the sixth one free.
It started with me drinking 500 ml of water two hours before the the scan. On arrival, I was weighed (I guess to help calculate how much Gallium-68 to inject?), and the tech started an IV. He walked away and wheeled in a cart with a small, lined box containing the injection syringe, and pushed the glow juice into my arm through the IV.
Once the juice was in, he removed the IV, and I leaned back in my recliner for the hour-long wait for the juice to make its way through my system. At the end of the hour, we headed to the scanner room where I emptied my pockets, jumped on the scanner table, and got strapped in so my arms wouldn’t move.
The scanner wasn’t claustrophobic for me, and it took 41 minutes to run up my body (they start at the thighs and work their way up to the head).
When I was through, I hopped off the table, collected my things, and headed home.
I have to admit that when I walked out of the hospital, I was really surprised by how much my body and mind unwound from the apparent subconscious nervous tension I was harboring. Going into it, I didn’t seem fazed by it all. It was routine for me. Heck, I’m on a first-name basis with the nuclear medicine tech (we’ll call him Sam) because he’s done all three of my scans at the VA. But apparently my subconscious had a different experience. Oh well. Nothing a good nap won’t cure.
I asked Sam how quickly the results would be available, and he said it could be as soon as this afternoon, but within 48 hours if they’re not.
From my previous scans with Sam, I’ve learned to not even think of asking him if he saw anything of concern during the course of the scan. He resoundingly (and rightly) always answered that it’s up to the doctor to interpret and provide the results.
I’ve also come to know that, for Sam, bedside manners seem to be optional. He’s not unprofessional in any way, but he is all business and sometimes even borders on the grumpy side. As I was leaving, Sam said something in such a way that he let his tough façade down. His voice became just a hint softer as he said, “You take care now” in a caring way.
Of course, that caught my attention and got my mind racing. I’m really, really, really trying not to read too much into that and get ahead of the actual results, but he said it two more times before I left. That makes me wonder what he saw that may have changed his demeanor.
Of course, my exhausted Gallium-68-infused brain may be making all this crap up, and I may get a good laugh out of it in a day or two. Or not.
As usual, stay tuned for the next chapter in this saga. I have my appointment to go over the results on 24 March.
This will be a short update, as not much has really happened in the last month.
Tomorrow, I have my third PSMA PET scan. With luck, we’ll actually find the location of the cancer with this scan. That will help us decide what’s next in this adventure. I suspect I should be able to access the results online within a week or so. If not, I have a follow-up appointment on 1 April with the urologist.
I was going to get my PSA test done next week, but I wasn’t sure what impact a potential government shutdown might have on access to the lab, so I went for the blood draw on Monday. I’m guessing that I’ll break the 1.0 ng/mL threshold with this test.
That’s it for now. More to come in the days ahead.

To my regular readers, you may want to skip this post. This is a high-level update intended for my family and friends who don’t regularly follow this blog (gasp!), and it will be shared with them via my personal social media accounts.If you’re new here, welcome. Feel free to read away.
It’s been a while since I’ve provided any detailed update on what’s going on in the world of my prostate cancer, so here goes.
We last left our hero two years ago as he began 35 sessions of salvage radiation therapy on 7 July 2022 in attempt to kill off his recurrent prostate cancer after his surgery in January 2011 ultimately failed. Unfortunately, those little cancer cells have proved themselves to be quite resilient, and the salvage radiation therapy has failed, too. Bummer.
We know this by tracking my prostate-specific antigens (PSA) on a regular basis. After the surgery, my PSA level should have dropped to undetectable (zero) because there was no prostate left to produce the PSA. But the PSA can live on in the cancer cells even without a prostate, and that’s how we know the cancer is still there.
After the radiation, my PSA should have dropped substantially, and it did, at least initially. But about 15 months after the radiation ended, my PSA was on the rise again. It rose enough to the surpass the PSA level when we started the radiation. In May 2024, it continued its upward climb to 0.52 ng/mL, the highest it’s been since the surgery. (In the grand scheme of things, it’s still a low value that many fellow prostate cancer patients would love to have, but the fact that it’s doubling about every six months is a concern.)
There is a relatively new scan that can detect prostate cancer cells at fairly low PSA levels. It works best when the PSA is close to 1.0 ng/mL, but it has detected prostate cancer about 30% of the time at PSA levels in the 0.2–0.3 ng/mL range. I went for this PSMA PET scan in January when my PSA was 0.37 ng/mL, and the scan failed to detect anything.
On the one hand, that’s great because there were no signs of metastasis and no evidence of prostate cancer. But on the other hand, we need to know where the cancer is located and what it’s up to in order to plan our next treatment options. Because it didn’t reveal its ugly head, we can’t make any meaningful treatment decisions right now.
If there are one or two small lesions someplace, we may be able to radiate them again depending on their size and location. But if there aren’t any distinct lesions and my PSA continues to increase, that’s likely the result of micrometastases and that would require a systemic treatment approach (e.g., hormone therapy, immunotherapy, chemotherapy, or any combination thereof).
After reviewing my May PSA results with the urologist, we agreed to punt for six months and do another PSA test in late October. I know that seems counterintuitive—letting the cancer continue to grow without taking action—but there’s a reason for it. I’m predicting my PSA at that point will be in the 0.75–1.0 ng/mL range in October, and we’ll do another PSMA PET scan to see if we can determine what’s going on and then plan from there.
Up until this year, all of my conversations have been with the urologist and radiation oncologist. In February, I met with a medical oncologist for the first time because they’re the ones who deal with the systemic treatments.
Based on my conversations with the urologist and medical oncologist, the next logical treatment option is hormone therapy. Prostate cancer lives off of testosterone, so if we kill off the testosterone, we slow the growth of the cancer cells. (Hormone therapy is not curative, however.) But the timing of starting hormone therapy is important.
If we started the hormone therapy now, it would rapidly knock my PSA down so far that it would make it next to impossible to do the PSMA PET scan in November and get any meaningful results.
The other problem with starting hormone therapy too early is that the prostate cancer can become hormone resistant much in the same way that bacteria can become resistant to antibiotics. Start the treatment too early, and you’ll lose its effectiveness when you really need it later.
There seemed to be a differing of opinions between the urologist and the medical oncologist as to what would trigger the start of hormone therapy. The urologist would hold off until there’s evidence of metastasis; the medical oncologist suggested we’d start when my PSA hit 2.0 ng/mL. We can figure that out when the time comes, but both agreed that hormone therapy (and other therapies) can keep me around another 10–15 years (or more).
Of course, my quality of life may be diminished as a result of the treatments. Hormone therapy can come with a whole host of unpleasant side effects such as fatigue, muscle loss, weight gain, loss of libido, hot flashes, etc. No need to rush into that Disneyland of experiences.
Physically, I am feeling fine. I’m completely asymptomatic when it comes to the cancer, but the side effects from the surgery and radiation are present and are a nuisance more than anything. Psychologically, though, it’s been a bit of an emotional roller coaster ride as I go from PSA test to PSA test, and failed treatment option to failed treatment option. We’re closing in on 14 years since diagnosis, and it does get tiring.
One of my regular blog readers and my urologist both suggested that, at this point, I look at my prostate cancer more as a chronic illness than as a life-threatening disease. I’m still trying to embrace that perspective and, even if I do, the worry will never go away.
There you have it. The latest and greatest in this adventure of living with prostate cancer. Follow along if you want to see my monthly updates, and we’ll probably know more right around the holidays.
Be well!
