How Is Metastatic Prostate Cancer Detected And Treated In Men Over 70?
~5.5 mins read
Questions and answers about the specifics of diagnosing and treating older men whose cancer has metastasized.

National guidelines on prostate cancer screening with the PSA test are set by the US Preventive Services Task Force (USPSTF). This independent panel of experts in preventive and primary care recommends against screening for prostate cancer in men older than 70.
Why? Prostate cancer tends to be slow-growing. Men in this age group are more likely to die with the disease rather than from it. And in the view of the USPSTF, survival benefits from treating PSA-detected prostate cancer in older men are unlikely to outweigh the harms of treatment.
Still, that leaves open the possibility that men could be screened for prostate cancer only after their disease has advanced to symptomatic stages. For a perspective on PSA screening and advanced prostate cancer treatment in older men, we spoke with Dr. Marc B. Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, and editor in chief of the Harvard Medical School Guide to Prostate Diseases.
Q. How often should men over the age of 70 be screened for prostate cancer?
Such testing is performed outside of guidelines, and generally following a discussion with the patient’s physician. It's not unusual for us to find advanced metastatic prostate cancer in older men flagged by a PSA test. The disease might spread asymptomatically, but some men get a PSA test only after they have advanced prostate cancer symptoms such as trouble urinating, fatigue, or bone pain.
The USPSTF's PSA screening guidelines are long overdue for an update — they were last published in 2018. And with life expectancy increasing overall for men over 70, we are all anxiously awaiting the new guidelines, which are generally updated every six years.
Q. What sort of other tests follow after a positive result with PSA screening?
Typically, a prostate needle biopsy. And I also recommend a digital rectal exam (DRE) to feel for any abnormalities in the prostate gland. President Biden was having urinary symptoms at the time of his PSA test, and he was reported to have had a nodule noted on his DRE. We do not know what his PSA score was.
Recently, we've been moving toward magnetic resonance imaging scans of the prostate that provide more diagnostic information, and can serve as a guide to more precisely identify abnormalities in the prostate gland that we can sample with a biopsy.
Q. How do we know if the cancer is likely to spread aggressively?
The more aggressive tumors have cells with irregular shapes and sizes that can invade into adjoining tissues. A time-honored measure called the Gleason score grades the two most common cancer cell patterns that pathologists see on a biopsy sample.
That system has now undergone some labelling changes. To simplify matters, doctors developed a five-tier grading system that ranks tumors from Grade Group 1 — the least dangerous — to Grade Group 5, which is the most dangerous. These Grade Groups still correlate with Gleason scores. For instance, a Gleason score of 3+3=6 correlates with Grade Group 1 for low-risk prostate cancer, whereas a Gleason score of 4+5=9 for high-risk disease correlates with Grade Group 5.
We can also evaluate how fast cancer cells are dividing — this measure is called mitotic rate — or order genetic tests that provide additional information. We know that men who test positive for inherited BRCA1 and BRCA2 gene mutations are at risk for more aggressive disease, for instance. BRCA test results also have implications for family members, since the same mutations elevate risks for other inherited cancers including breast cancer and ovarian cancer.
Q. How do you know if the cancer is metastasizing?
Traditionally, patients would get a computed tomography scan of the abdomen and pelvis along with a bone scan. These tests look for metastases in the lymph nodes and bones, but they are increasingly outdated. These days, doctors are more likely to scan for a protein called prostate-specific membrane antigen (PSMA) that can be expressed at high levels on tumor cell surfaces.
A PSMA scan is much better at detecting prostate tumors in the body that are still too small to see with other imaging tests. If the scans show evidence of metastatic spread, we classify men as having either high- or low-volume disease depending on the extent. Men with no more than three to five metastases are described as having oligometastatic prostate cancer.
Q. What treatment options are available for metastatic prostate cancer?
We generally don't begin with a single drug. Men with low-volume metastatic prostate cancer typically get doublet therapy, which is a combination of two drugs that each starve tumors of testosterone, a hormone that prostate cancer needs to grow.
One of the drugs, called leoprolide (Lupron), blocks testosterone production. The other drugs are drawn from a class of medications that prevent testosterone from binding to its cell receptor. Those drugs are called androgen receptor pathway inhibitors (ARPIs). They include enzalutamide (Xtandi), daralutamide (Nubeqa), apaludamide (Erleada), or another drug with a slightly different mechanism called abiraterone (Zytiga).
If the cancer progresses on doublet therapy, then we can add chemotherapy to the mix. This is called triplet therapy (Lupron + ARPI + chemotherapy). We may also recommend immediate triplet therapy depending upon the extent of the cancer spread.
Some men are eligible for other treatments as well. For instance, men with PSMA-positive disease (meaning their cells express the protein in high amounts) can be treated with an intravenously-delivered therapy called Lutetium-177. Known as a radioligand, this type of therapy seeks out PSMA-expressing cells and kills them with tiny radioactive particles.
Some men are eligible for metastasis-directed therapy (MTD). In such cases, we treat metastatic deposits with highly focused beams of radiation delivered from outside the body. MTD is generally reserved for patients with oligometastatic prostate cancer.
Q. What happens if a patient is positive on a genetic test for prostate cancer?
That opens up options for so-called targeted therapy — which is a term we use to describe treatments that target specific cell changes that cause tumors to grow. Patients with BRCA1 or BRCA2 mutations, for instance, can start on doublet therapy plus a targeted therapy called a PARP inhibitor. Two PARP inhibitors are approved for prostate cancer in BRCA-positive men: olaparib (Lynparza) and rucaparib (Rubraca). Men with a different gene mutation called microsatellite instability are eligible for a targeted drug called pembrolizumab (Keytruda).
Q. How is the outlook for metastatic prostate cancer changing?
It's improving dramatically! Metastatic prostate cancer used to carry a very poor prognosis. Today, it's not unusual for men to live 10 years or longer with the disease. We're even starting to treat cancer in the prostate directly — something we didn't do in the past since the cancer had already spread beyond the prostate gland. More recent studies have shown improvements from delivering radiation to the prostate gland itself in patients with metastatic cancer. We're including these treatments more often now, which is something we wouldn't have considered before.
Q. Any final notes?
I would advise men to undergo a cardiac evaluation prior to starting on hormonal therapy. Hormonal therapies can exacerbate cardiovascular risk factors, so these should be addressed before and during treatment.
Thanks for your insights!
You're very welcome, glad to help.

Wildfires: How To Cope When Smoke Affects Air Quality And Health
~3.5 mins read
Smoke from regional wildfires endangers health even for those not directly in the path of fire.
Create an evacuation plan for your family before a wildfire occurs.
Make sure that you have several days on hand of medications, water, and food that doesn’t need to be cooked. This will help if you need to leave suddenly due to a wildfire or another natural disaster.
Regularly check this fire and smoke map, which shows current wildfire conditions and has links to state advisories.
Follow alerts from local officials if you are in the region of an active fire.
Stay aware of air quality.AirNow.gov shares real-time air quality risk category for your area accompanied by activity guidance. When recommended, stay indoors, close doors, windows, and any outdoor air intake vents.
Consider buying an air purifier. This is also important even when there are no regional wildfires if you live in a building that is in poor condition. The EPA recommends avoiding air cleaners that generate ozone, which is also a pollutant.
Understand your HVAC system if you have one. The quality and cleanliness of your filters counts, so choose high-efficiency filters if possible, and replace these as needed. It’s also important to know if your system has outdoor air intake vents.
Avoid creating indoor pollution. That means no smoking, no vacuuming, and no burning of products like candles or incense. Avoid frying foods or using gas stoves, especially if your stove is not well ventilated.
Make a “clean room.” Choose a room with fewer doors and windows. Run an air purifier that is the appropriate size for this room, especially if you are not using central AC to keep cool.
Minimize outdoor time and wear a mask outside. Again, ensuring that you have several days of medications and food that doesn’t need to be cooked will help. If you must go outdoors, minimize time and level of activity. A well-fitted N95 or KN95 mask or P100 respirator can help keep you from breathing in small particles floating in smoky air.

As wildfires become more frequent due to climate change and drier conditions, more of us and more of our communities are at risk for harm. Here is information to help you prepare and protect yourself and your family.
How does wildfire smoke affect air quality?
Wildfire smoke contributes greatly to poor air quality. Just like pollution from burning coal, oil, and gas, wildfires create hazardous gases and tiny particles of varying sizes that are harmful to breathe. Wildfire smoke also contains other toxins that come from burning buildings and chemical storage.
Smoke carried by weather patterns and jet streams can cross state and national boundaries, traveling to distant regions.
How does wildfire smoke affect our health?
The small particles in wildfire smoke –– known as particulate matter, or PM10, PM2.5, PM0.1 –– are the most worrisome to our health. When we breathe them in, these particles can travel deep into the lungs and sometimes into the bloodstream.
The health effects of wildfire smoke include eye and skin irritation, coughing, wheezing, and difficulty breathing. Other possible serious health effects include heart failure, heart attacks, and strokes.
Who needs to be especially careful?
Those most at risk from wildfire smoke include children, older adults, outdoor workers, and anyone who is pregnant or who has heart or lung conditions.
If you have a chronic health condition, talk to your doctor about how the smoke might affect you. Find out what symptoms should prompt medical attention or adjustment of your medications. This is especially important if you have lung problems or heart problems.
What can you do to prepare for wildfire emergencies?
If you live in an area threatened by wildfires, or where heat and dry conditions make them more likely to occur:
What steps can you take to lower health risks during poor air quality days?
These six tips can help you stay healthy during wildfire smoke advisories and at other times when air quality is poor:

Stepping Up Activity If Winter Slowed You Down
~4.7 mins read
Better health, better mood, better balance, and a multitude of other benefits await.
heart disease
stroke
diabetes
cancer
brain shrinkage
muscle loss
weight gain
poor posture
poor balance
back pain
and even premature death.
If it's cold outside: It's generally safe to exercise when the mercury is above 32° F and the ground is dry. The right gear for cold doesn't need to be fancy. A warm jacket, a hat, gloves, heavy socks, and nonslip shoes are a great start. Layers of athletic clothing that wick away moisture while keeping you warm can help, too. Consider going for a brisk walk or hike, taking part in an orienteering event, or working out with battle ropes ($25 and up) that you attach to a tree.
If you have mobility issues: Most workouts can be modified. For example, it might be easier to do an aerobics or weights workout in a pool, where buoyancy makes it easier to move and there's little fear of falling. Or try a seated workout at home, such as chair yoga, tai chi, Pilates, or strength training. You'll find an endless array of free seated workout videos on YouTube, but look for those created by a reliable source such as Silver Sneakers, or a physical therapist, certified personal trainer, or certified exercise instructor. Another option is an adaptive sports program in your community, such as adaptive basketball.
If you can't stand formal exercise: Skip a structured workout and just be more active throughout the day. Do some vigorous housework (like scrubbing a bathtub or vacuuming) or yard work, climb stairs, jog to the mailbox, jog from the parking lot to the grocery store, or do any activity that gets your heart and lungs working. Track your activity minutes with a smartphone (most devices come with built-in fitness apps) or wearable fitness tracker ($20 and up).
If you're stuck indoors: The pandemic showed us there are lots of indoor exercise options. If you're looking for free options, do a body-weight workout, with exercises like planks and squats; follow a free exercise video online; practice yoga or tai chi; turn on music and dance; stretch; or do a resistance band workout. Or if it's in the budget, get a treadmill, take an online exercise class, or work online with a personal trainer. The American Council on Exercise has a tool on its website to locate certified trainers in your area.

If you've been cocooning due to winter's cold, who can blame you? But a lack of activity isn't good for body or mind during any season. And whether you're deep in the grip of winter or fortunate to be basking in signs of spring, today is a good day to start exercising. If you're not sure where to start — or why you should — we've shared tips and answers below.
Moving more: What's in it for all of us?
We're all supposed to strengthen our muscles at least twice a week and get a total at least 150 minutes of weekly aerobic activity (the kind that gets your heart and lungs working). But fewer than 18% of U.S. adults meet those weekly recommendations, according to the CDC.
How can choosing to become more active help? A brighter mood is one benefit: physical activity helps ease depression and anxiety, for example. And being sufficiently active — whether in short or longer chunks of time — also lowers your risk for health problems like
What are your exercise obstacles?
Even when we understand these benefits, a range of obstacles may keep us on the couch.
Don't like the cold? Have trouble standing, walking, or moving around easily? Just don't like exercise? Don't let obstacles like these stop you anymore. Try some workarounds.
Is it hard to find time to exercise?
The good news is that any amount of physical activity is great for health. For example, a 2022 study found that racking up 15 to 20 minutes of weekly vigorous exercise (less than three minutes per day) was tied to lower risks of heart disease, cancer, and early death.
"We don't quite understand how it works, but we do know the body's metabolic machinery that imparts health benefits can be turned on by short bouts of movement spread across days or weeks," says Dr. Aaron Baggish, founder of Harvard-affiliated Massachusetts General Hospital's Cardiovascular Performance Program and an associate professor of medicine at Harvard Medical School.
And the more you exercise, Dr. Baggish says, the more benefits you accrue, such as better mood, better balance, and reduced risks of diabetes, high blood pressure, high cholesterol, and cognitive decline.
What's the next step to take?
For most people, increasing activity is doable. If you have a heart condition, poor balance, muscle weakness, or you're easily winded, talk to your doctor or get an evaluation from a physical therapist.
And no matter which activity you select, ease into it. When you've been inactive for a while, your muscles are vulnerable to injury if you do too much too soon.
"Your muscles may be sore initially if they are being asked to do more," says Dr. Sarah Eby, a sports medicine specialist at Harvard-affiliated Spaulding Rehabilitation Hospital. "That's normal. Just be sure to start low, and slowly increase your duration and intensity over time. Pick activities you enjoy and set small, measurable, and attainable goals, even if it's as simple as walking five minutes every day this week."
Remember: the aim is simply exercising more than you have been. And the more you move, the better.
