New German study below [1].

The elderly patients were at least 75 at diagnosis.

Only 2 more years & I will finally be elderly. I wonder what it will be like? LOL. As a group, older guys obviously have shorter life expectancy, but there has to be a better way to define 'elderly' than age. What about comorbidities & shouldn't there be some credit for those who run 10 miles before breakfast, etc?

"Of 6556 patients, 1105 received EBRT (16.9%). M1b stage was predominant in both EBRT (n = 823; 74.5%) and no EBRT (n = 3908; 71.7% ...) groups, followed by M1c (n = 211; 19.1% vs. n = 1042; 19.1%, ...) and M1a (n = 29; 2.6% vs. n = 268; 4.9%, ...).

"Median overall survival (OS) was 23 months for EBRT and 23 months for no EBRT (hazard ratio [HR] ...).

"Similarly, median cancer-specific survival (CSS) was 29 months for EBRT versus 30 months for no EBRT (HR: 1.04 ...).

"After additional multivariable adjustment, EBRT was not associated with lower {overall mortality} or lower {cancer-specific mortality} in the entire cohort, as well as after stratification for M1b and M1c substages."

"... our findings question the added value of local EBRT in elderly newly diagnosed mPCa patients."

Abstract

Background: The survival benefit of primary external beam radiation therapy (EBRT) has never been formally tested in elderly men who were newly diagnosed with metastatic prostate cancer (mPCa). We hypothesized that elderly patients may not benefit of EBRT to the extent as younger newly diagnosed mPCa patients, due to shorter life expectancy.

Methods: We relied on Surveillance, Epidemiology and End Results (2004-2016) to identify elderly newly diagnosed mPCa patients, aged >75 years. Kaplan-Meier, univariable and multivariable Cox regression models, as well as Competing Risks Regression models tested the effect of EBRT versus no EBRT on overall mortality (OM) and cancer-specific mortality (CSM).

Results: Of 6556 patients, 1105 received EBRT (16.9%). M1b stage was predominant in both EBRT (n = 823; 74.5%) and no EBRT (n = 3908; 71.7%, p = 0.06) groups, followed by M1c (n = 211; 19.1% vs. n = 1042; 19.1%, p = 1) and M1a (n = 29; 2.6% vs. n = 268; 4.9%, p < 0.01). Median overall survival (OS) was 23 months for EBRT and 23 months for no EBRT (hazard ratio [HR]: 0.97, p = 0.6). Similarly, median cancer-specific survival (CSS) was 29 months for EBRT versus 30 months for no EBRT (HR: 1.04, p = 0.4). After additional multivariable adjustment, EBRT was not associated with lower OM or lower CSM in the entire cohort, as well as after stratification for M1b and M1c substages.

Conclusions: In elderly men who were newly diagnosed with mPCa, EBRT does not affect OS or CSS. In consequence, our findings question the added value of local EBRT in elderly newly diagnosed mPCa patients.

Hello Patrick,

I'm now 80; diagnosed at 70. Conversation between my MO and me:

MO: "Nobody lives forever."

Me: "Records are made to be broken."

Attitude certainly helps.

Definition of “elderly” is in the eyes (or opinion) of the observer. For me it is my age plus 10 years. Used to define middle aged in the same way. But that stopped working sometime after 50.I do sort of meet the ten miles before breakfast standard. I walk or hike 6 to 10 miles Nearly every day. And I don’t eat breakfast at all on my One-Meal-A-Day intermittent fasting. 😆

Perhaps another definition would be:Those men with metastatic PC who will not benefit with increased overall survival from aggressive therapies

There are different types of age such as Physical age, Mental age, biological age and emotional age...A75 years old man who walks/ runs 10 miles a day and does not have many serious medical conditions and is fit and trim....the biological age is 50 ..though physical age is 75.

Thanks for sharing this, though sadly disappointed with the study conclusion.

It will be interesting to see what specialist physicians say about this study.

LA hits some notes of resonance to identify with...

Physical, Mental, Emotional...

All can have "Age" standards associated with them. And for everyone, they can be and are different.

A lot of times, it's all within the control of the person themselves.

I know I have some family members that although in their 40's are still the mindset of 20 something! I have others who are very mature for their age! (I have a BIG family) lol...

Bottomed line is sometimes Soul Searching can help in providing an awakening, or the ability to see yourself without obstruction and have a real time assessment. Thought then is do you like what you see? Are you comfortable in your own skin? Do you own it and skip down the street not worrying about what others think? What most effects your thoughts here.

AGE for the most part, truly is a state of mind! And the MIND is a terrible thing to waste! Lol

The mind can power you through that workout you don't want to do. It can get you those 2 extra pushups. It can encourage you to see something through to it's conclusion, regardless of the results. It provides the mettle of which we are made of. I'm currently in the midst of all this and is why it is all fresh to mind and that I can maybe relate to it. Ultimately, it is different for everyone, but similar as well when we stumble across it.

Best Regards

One of my grandfathers when he developed dementia and or Alzheimer's my mom took him into her house and under her care. He was about 96 years old at that time (unfortunately not my biological grandfather lol).Every morning same thing " I know where I am but not how or why I am at your house".

She would re-explain every day.

He would ask sometimes how old am I. "How old do you think"?

Sometimes his reply was 50 other times 65.

His "old" memories were somewhat intact.

One day he saw a newspaper.

1998!!!!Jesus Christ!!!! He proclaimed in utter shock.

So, if I make it to 96 but my Alzheimer's gene has kicked in, I might still have some basic math skills? Good to know. LOL
