So, let’s walk through the types of therapy that are used today to treat prostate cancer. If you would start with surgery?

Dr. Choudhury:            

Sure. So, surgery is a radical prostatectomy, and they take out the prostate – they take out neighboring structures called seminal vesicles, they take out the surrounding fat, and they’ll usually take out some neighboring lymph nodes as well. And there are advantages of surgery in that when the prostate is out, the pathologist can examine the whole prostate front to back, side to side, as well as those neighboring structures to really understand the stage of the cancer – “Where is it?” – and also, the grade – “Is it a high-grade cancer, a low-grade cancer, somewhere in the middle?”

And it really helps guide “What is the risk of developing recurrence afterwards, and are there further treatments that we should be giving after the surgery? For example, radiation to the prostate bed to decrease the risk of recurrences. Surgery does have its own set of potential side effects and complications, so it’s not appropriate for everyone, but in general, that’s the process.


What other treatment options? You mentioned radiation. What else is there?         

Dr. Choudhury:          

Yeah, so, radiation comes in two forms: there’s seed radiation, which is implantable little radioactive pellets that are implanted throughout the prostate. And then, there’s external radiation, and that can be given in several forms and over several schedules that it’s really important to discuss with the care team.

The other forms of treatment that people on this call might’ve heard about or read about are in a category called “focal treatments,” and these are basically ways to – and the term we use is a blade but zap – an area of the prostate using lasers, or high-intensity ultrasound, or with freezing an area of the prostate, or with something called “irreversible electroporation.”

These are basically all ways to, again, zap an area of the prostate either with heat or with cold with the intention of killing off cancer cells in an area. And the trouble is that none of these treatments have actually been demonstrated to improve outcomes related to prostate cancer compared to just surveillance alone. And it does complicate, sort of, the monitoring afterwards to see if something has come back.

But there might be very selected patients where there’s an area of cancer that’s seen on a scan – like an MRI – with no cancer seen outside of that area who might decide to pursue this possibility of focal treatment with the goal of maybe putting off the need for something like radiation or surgery. But that’s something that really should be discussed with a multidisciplinary team so that people really understand what they’re getting into in terms of risks and potential benefits.

So, those treatments are not really considered standard at this time.


What about hormonal therapy?        

Dr. Choudhury:   

Yeah, so, hormonal therapy plays a role in the treatment of prostate cancer, really depending on the stage and the other treatments that are being considered. So, for example, if a patient is going to surgery for a localized prostate cancer, in general, we wouldn’t use hormonal treatment either before or after the surgery unless they’re planned for radiation after the surgery.

However, for patients who have intermediate risk or higher localized prostate cancer and are getting radiation, then we will often recommend hormonal treatments, which are basically testosterone-lowering drugs, to make the radiation work as well as possible. And then, for patients who have advanced cancer beyond where surgery or radiation is going to be of help, then, hormonal treatments are important to treat the cancer wherever it is.

And that’s because prostate cancer cells, wherever they are in the body – wherever they’re in the prostate itself, or in lymph nodes, or bones, or other organs – depend on the testosterone in your body to supply a fuel – to support its growth and survival.

And so, lowering the level of testosterone in the body basically deprives the cancer cells of that fuel and starts a process of killing cancer cells even without any need for radiation, or chemotherapy, or things like that. However, hormonal treatments are not curative. They don’t kill all the cancer – they kill some and put the rest to sleep. And so, if you stop the hormonal treatment, the cancer will grow back, and that’s why it’s not a treatment on its own for localized prostate cancer.

And that’s also why, for prostate cancer that’s spread, we often add on additional medications to the testosterone-lowering drugs to be more effective at really killing the cancer wherever it is compared to the testosterone suppression alone.


Oh, I see. For advanced disease, what treatments are available for patients that are hormone-sensitive or -resistant?

Dr. Choudhury:           

Yeah, so “hormone-sensitive” means that the cancer has advanced, but the patient hasn’t started on testosterone-lowering drugs yet. And so, as I had mentioned, testosterone lowering is really the backbone of treatment of these patients. And so, there are additional treatments that have been demonstrated previously to be effective after testosterone-lowering by itself stops working, and these include a chemotherapy drug called docetaxel. And in addition, there are more potent hormonal drugs called abiraterone, enzalutamide, apalutamide, and darolutamide.

And the role of these other drugs is to block hormonal signaling within the cancer cells from hormones other than testosterone. And so, by doing the more potent hormonal drug in conjunction with the testosterone lowering, that leads to a much deeper response – much more tumor shrinkage – and, it turns out, also prolonged survival in patients treated with those combination treatments – compared top people who are treated with testosterone lowering alone and then receive these drugs later.

So, there’s something about treating more aggressively at the beginning in this hormone-sensitive state that plays out in prolongation of survival. And not only prolonged survival, but improved quality of life due to delaying the symptoms of cancer grown and progression.



Dr. Choudhury:   

When we then talk about castration resistant disease, certainly we use the same classes of drugs, but then, there’s a wider armamentarium of things that we use that include, again, other kinds of chemotherapy.

There are radiation drugs, and an approved drug Radium-223. And there’s another drug on the horizon called Lutetium PSMA. There are immune therapy drugs – something called Sipuleucel-T – and then, this is also a situation where we do genetic testing of the cancer to understand if there’re certain –what we call “therapeutic vulnerabilities.”

Other treatment options that are available based on the genetics of the cancer that might be helpful in some people? And specific options include a chemo-immune therapy called “Keytruda” in a small subset of patients with particular genetic changes involving genes involved in mismatched repair of DNA. And then, there’s another set of targeted treatments called “PARP inhibitors” for certain sets of patients who have alterations in genes involved in homologous recombination repair of DNA.

So, that’s all very complicated, and so that’s why it’s important to get treated with high-volume providers of prostate cancer patients so that they’re really aware and onboard with these various treatment options that are available.

How Does Stress Correlate With Your Prostate Cancer Diagnosis?



Dr. Leanne Burnham

Yes, so it is a couples’ disease for sure, and you want to make sure to do a little bit of your own research. Make sure that your doctor knows how this disease affects Black men differently, because what I see a lot of time, even in my own family, my husband’s family members that get prostate cancer and they come to me, a lot of times, their doctor will recommend active surveillance. And it may not be appropriate for African American men if you look at the research and you look at the studies. And so, it may benefit you to just ask your doctor, “Do you treat a lot of Black patients, or do you see any difference in their survival rates versus your other patients?” And really consider that when you’re thinking about whether to do active surveillance or not. Once it gets time for treatments, one thing when I — because I talk to a lot of men and support groups, and men are scared, they don’t want to lose their urinary function, they don’t want to lose their sexual function. And so, they’re nervous about certain diseases and in terms of surgeries and radical prostatectomy, there are nerve-sparing surgeries now to really protect that function afterwards, and there are exercises that can be done afterwards to also help improve, and so ask the nurses in your setting, “What are some of those exercises that can be done?” But one thing to keep in mind is every treatment comes with its sort of risk, right?

So, no matter whether you choose radiation or surgery, there’s always a risk that you may lose some of that function, what I tell men, and not to sound not sensitive to the matter, but a lot of men, they’ll say, you know, “Oh, if I get this treatment and what if I can’t have sex anymore?” You’re not going to have sex when you’re buried 6 feet underground either. And so, you want to be able to get those treatments, the ones that you and your physician have a shared decision in and in deciding what’s best as a couple. But you don’t want to be naive if you’re at the doctor and you have a really elevated PSA and you have a Gleason score of 8, and your doctor is telling you, “We really need to treat this,” you don’t want to shy away from that, because you’re scared of the side of the side effects in that setting. You can look for where the best surgery center is if they have the nerve-sparing surgery, as I said, and explore your options that way. But don’t put it off so long, because you’re worried about the side effects. And if you don’t get treatment and your doctor wants you to, as time goes on, you’ll lose the urinary function and the sexual function anyways.

So yeah, it’s not something that you want to put off because you’re scared about the side effects. And a lot of men do have side effects temporarily, and then they regain their function, and I really encourage to join support groups virtually now because of how the role is set up. But just talk to some other men that have had some of these procedures and see how they’re doing. And I personally haven’t met a man that felt like, “Oh, I have been cured from prostate cancer, and now I have the side effects, and I wish I wouldn’t have had the procedure,” I haven’t met one. And I know in those who have side effects and they had surgeries and 10, 15 years ago, and they have side effects, I’m not going to act like that doesn’t happen. But none of them have ever expressed to me that they wish they could go back in time and not do that, because, at the end of the day, they’re grateful that they are still here with their loved ones.
