In a press release from his private workplace on Could 18, former President Joe Biden revealed he has an aggressive type of prostate most cancers that has unfold to his bones. “Whereas this represents a extra aggressive type of the illness, the most cancers seems to be hormone-sensitive which permits for efficient administration,” his workplace stated in a press release. “The President and his household are reviewing therapy choices along with his physicians.”
Current studies present that survival for males with prostate most cancers that has unfold to the bone is slightly below two years. However this type of most cancers, although aggressive, can generally be managed. This is what oncologists who deal with prostate most cancers say are the most typical methods for treating a most cancers like Biden’s, and among the challenges.
The most recent methods to curb aggressive prostate most cancers
“The excellent news is that this: now we have now entered an period of various therapies that I name remedy intensification the place we try to assault most cancers with a multi-modality strategy,” says Dr. Maha Hussain, deputy director of the Robert H. Lurie Complete Most cancers Heart at Northwestern College Feinberg College of Drugs. “We are able to provide you with a major prolongation of life by comparability to after I entered the sector.” She has seen sufferers with prostate most cancers that has unfold survive and “reside many, a few years.”
Most prostate most cancers is fueled by the male hormone testosterone, so the best methods to manage it starve the most cancers by chopping off its provide, say consultants. Traditionally, docs have eliminated the testes—the principle supply of the hormone—however in the present day, capsules and injections can suppress testosterone not simply within the testes however in different organs that produce small quantities, such because the adrenal glands, as properly. Docs additionally now add chemotherapy to hormone-suppression to higher management most cancers development.
Precisely which combos of therapies are proper for Biden will rely on whether or not his most cancers is new or if it was beforehand identified and not too long ago re-emerged. Both situation is feasible, say consultants.

With respect to having prostate most cancers initially identified at such an aggressive state, after it has already unfold, “I don’t suppose there’s any cause to suppose this might not be the pure historical past of prostate most cancers in an older particular person,” says Dr. Robert Figlin, most cancers heart director at Cedars-Sinai Most cancers Heart. “And this may not [indicate] one thing that was missed or mismanaged in previous years. That is actually one thing that may happen in the midst of a male’s life—it’s common to current on this method.” Many older males are identified with aggressive illness, with studies exhibiting that about 20% of prostate most cancers circumstances are identified in males 75 years and older, and that males 70 and older tended to have higher Gleason scores, an indicator of the most cancers’s aggressiveness, at analysis. (Biden’s Gleason rating is 9, his workplace stated within the assertion, indicating a extra aggressive most cancers.) “Prostate most cancers can sit dormant for years and all of the sudden determine to get up,” says Hussain. “I’ve seen every kind of circumstances—all shades of gray.”
Remedy choices additionally rely on a affected person’s total well being. Different circumstances an individual may need can have an effect on their capability to tolerate the therapies and unwanted effects. “We’ve got to keep in mind different ailments a person could have, different medical circumstances that could be life-limiting, targets that man has by way of longevity and high quality of life, and different drugs he could also be taking,” says Dr. Michael Morris, prostate most cancers part head at Memorial Sloan Kettering Most cancers Heart.
What about immunotherapy?
Immunotherapy—an thrilling new therapy that harnesses the immune system to struggle sure most cancers varieties—is thus far not efficient in opposition to prostate most cancers. Whereas it has been profitable in slowing melanoma, breast, lung, kidney and bladder cancers, and lymphoma, prostate most cancers stays comparatively hidden from the immune system, making it what docs name a “chilly” most cancers. “I’d fairly name it a sneaky most cancers,” says Hussain. “Prostate most cancers cells actually sit contained in the bone marrow subsequent to the white blood cells,” that are immune cells. “The white blood cells can’t see it, so in contrast to different cancers, prostate most cancers has nonetheless not been aware of immunotherapies.”

Nevertheless, whereas present immunotherapy methods is probably not as efficient in opposition to prostate most cancers, new immune-based interventions are being explored, says Morris. “For now, for a affected person who presents in the present day with prostate most cancers, there is no such thing as a actual function for immunotherapy,” he says. “However there are lots of methods of manipulating the immune system to activate in opposition to prostate most cancers. In case you ask me in one other couple of years, we can have a fairly a special message.”
Docs are additionally exploring whether or not introducing chemotherapy earlier, together with hormone-suppressing therapies might enhance their possibilities of controlling the most cancers and stopping it from spreading and changing into extra aggressive. “One of the vital essential questions for sufferers with newly identified metastatic illness would wish to reply is whether or not they want docetaxel chemotherapy along with [hormone suppressing] remedy,” says Dr. Timothy Daskivich, affiliate professor of urology at Cedars-Sinai. “Information means that sufferers with greater quantity metastases profit essentially the most from docetaxel. If these sufferers do not get it up entrance, it might be a missed alternative.”
Screening for prostate most cancers
Prostate most cancers screening—completed with a blood check for prostate particular antigen (PSA), a marker of most cancers cells—has helped to decrease deaths from the illness. However the screening has been controversial, since prostate most cancers typically grows slowly and the check can decide up indicators of benign prostate development, which additionally happens as males age.
Nevertheless, the American Most cancers Society presently recommends that males with common threat of prostate most cancers get screened starting at age 50, if they’re anticipated to reside no less than 10 extra years, and that males with greater threat, together with African-American males and people with a father or brother identified with the illness, begin earlier, at age 45. The U.S. Preventive Services Task Force recommends that the majority males cease screening at age 70, since at the moment, males could also be extra more likely to die of causes aside from prostate most cancers, and the dangers of over-treating slow-growing cancers could outweigh the advantages.
A legacy of advocacy for brand new approaches to most cancers
As vp below President Barack Obama, Biden led the Most cancers Moonshot to spur analysis into new therapies. As president in 2022, he set a nationwide purpose of lowering most cancers dying charges by 50% over 25 years. The search was private for Biden, whose son Beau died in 2015 of mind most cancers at age 46.
“Most cancers touches us all,” he wrote in an Instagram post on Could 19. “Like so lots of you, Jill and I’ve realized that we’re strongest within the damaged locations. Thanks for lifting us up with love and help.”
