Less than 0.1

I couldn't wait any longer, so I called for my PSA results. Once again, less than 0.1!

The Question

The Question comes up periodically, whenever it's time. The Question haunts my dreams, occupies my waking hours, and adds a tinge of uncertainty to everything.

What's my PSA?

If it remains less than 0.1, all will be well,and the Question will quickly recede in my mind, at least until the next test date approaches.

If my PSA is anything else, life will change radically, assuming it's not a lab error. It would mean my cancer was systemic, and incurable with today's medicine. There might be a second PSA test to confirm, with an interim waiting period of a few weeks to 3 months, or I might head straight to the medical oncologist--a prostate specialist. With a rising PSA after surgery and salvage radiation, there would be only one realistic option. Castration.

How's that for drama?

Now, I almost certainly would not choose surgical castration, but rather medical castration. Most people are squeamish about the word "castration" and so we say hormone therapy, or androgen deprivation--but the effect is the same. I would become a eunuch, lose all interest in sex, and hopefully the cancer would be stalled for years. And while it was stalled, I would probably stay on the therapy. If all went well, perhaps it would stave off metastasis for a decade or more. More likely, it would last a few years. There is intermittent therapy, where you get to take holidays from androgen deprivation, but it doesn't sound all that great to me either way.

In the next few days, I'll find out the answer to the Question.

Salvage Radiation: Nomogram updates

It looks like the Memorial Sloan-Kettering Salvage Radiation Therapy nomogram on Nomograms.org (direct URL: http://www.mskcc.org/applications/nomograms/prostate/SalvageRadiationTherapy.aspx ) has been updated. It's now easier to use and the response makes sense. It used to give your result as post-surgery rather than post-radiation.
I had been thinking that the nomogram was too pessimistic, compared to the paper version. But what I didn't realize was that four months after the paper version was released in the Journal of Clinical Oncology, an erratum was published that corrected a mistake in regards to pre-radiation androgen deprivation (hormonal therapy). The corrected PAPER version of this important tool is here: http://jco.ascopubs.org/content/vol25/issue26/images/large/zlj0150759390003.jpeg ; however, I see no reason to use it because the digital nomogram is much easier, quicker to use, and less prone to human error.

Now both paper and online versions tell me that I've got a 39% chance of being progression free at 6 years. That jibes pretty well with Catalona's research that showed that long term success with prostate salvage radiation is uncommon--only about 25% of patients overall are progression free at 10 years. Of those who had a complete response to radiation, as I did, Catalona found that 35% were free from PSA progression.

The full text of the original article (remember, the nomogram in this original article is not correct) is here: http://jco.ascopubs.org/cgi/content/full/25/15/2035.

If you have a rising PSA after prostatectomy, and you're considering salvage radiation, I encourage you to read the original article and use the online nomogram at Memorial Sloan-Kettering.

FLHW

I just ordered some bracelets from FLHW.org (Faith Love Hope Win), a charity run by David E. David is a guy about my age with advanced prostate cancer. His blog is one of the most compelling pieces of autobiography on the web.

I urge you to visit http://www.FLHW.org, buy a few bracelets, and read David's blog.

I think you'll agree that David is a true hero.

Undetectable PSA and odds of progression after salvage radiation

http://www.oncologystat.com/journals/journal_scans/Achieving_an_Undetectable_PSA_After_Radiotherapy_for_Biochemical_Progression_After_Radical_Prostatectomy_Is_an_Independent_Predictor_of_Biochemical_Outcome_Results_of_a_Retrospective_Study.html

If you achieve an undetectable PSA after salvage radiation, this study shows your odds of being progression free 3.5 years later are 75%. But if your PSA doesn't fall that low, your odds are only 18%.

ha!

From the March 2008 Atlantic Monthly "What's Your Problem?" Q&A column by Jeffrey Goldberg:

Is life after college really as monotonous and depressing as it looks?
--Ben, Manhattan, Kan.

Dear Ben,
No. It's worse! Just kidding. It's actually a joy. Except for the prostate exams.

Good news on PSA once again

Less than 0.1.

A deep sigh of relief. A new lease on life.

With that, as promised, I'm putting this blog to bed. Unless there is really big news in the area of salvage radiation, I don't plan on posting or updating. There is a news feed at the bottom of the page that's automatically populated by news from Google, but I won't be manually adding anything.

And if I hit the mark again on my next PSA, I will probably delete the blog, so that I'm not promulgating obsolete information.

In case you're wondering, YES, we will be celebrating. Magic Kingdom, here we come!
