Tapping into Your Own Immune System

Is that the best answer for incurable prostate cancer?

A rather new approach in treating prostate cancer is to use vaccines. The only prostate cancer vaccine to be approved so far is Provenge (sipuleucel-T) which was approved in 2010 to treat late stage prostate cancer and it is now being tested in trials to see if it can help at earlier stages (when your immune system is stronger).

A unique feature of vaccines is that they often use your own cancer cells to stimulate your immune system to identify and kill cancer cells. And the side effects are usually less severe than with other treatments. Cancer vaccines (immunotherapy) work much the same as the vaccines you have had for smallpox, measles, and other diseases, except it has been far more difficult with cancer. Unlike infections, which are caused by foreign organisms invading your body, cancer comes from within and therefore is much better at evading your immune system.

Some patients respond successfully to vaccines and others do not. Why that happens is still a mystery and the focus of research.

There are other vaccines being tested to find out if they might be effective in slowing or stopping prostate cancer. If you think a vaccine sounds like a good approach, here are a few names to check out at the National Cancer Institute.

·       Provenge (sipuleucel-T) already approved for late stage treatment, but new trials for earlier stage treatment use are being conducted.

·       Yervoy (ipilimumab) already approved for metastatic melanoma and in trials for prostate cancer.

·       Cabozantinib (XL184) in trials for thyroid cancer and recently for prostate cancer.

·       Dendritic Cell Vaccine Study DC/PC3 currently in phase I (safety) and phase II studies.

Progress is slow and the cost of using these vaccines has been very high. But the progress has been consistent and that’s always a good result when you’re looking for your own magic bullet or maybe just to slow down that damnable rising PSA.

My 100th Prostate Cancer Blog Entry! Big Deal or What?

Why would anybody in their right mind do this?

It took me three and a half years to get to 100 blogs. Others write that many entries in a few months. So speed wasn’t my strong suite.

I started out to provide short articles with the newest prostate cancer information, share my experiences with medications, side effects, and clinical trials. And I added a cartoon to almost every one to add a touch of humor—not necessarily politically correct. A few times I published a guest blog. Sometimes I summarized new information from cancer research. Most of the blog entries related at least partly to me, my life experiences, my friends with prostate cancer,  and I must confess to the odd complaint (some side effects really suck).

By the time I started the blog I already knew my prostate cancer was incurable. I had just published a book about prostate cancer and my ongoing story. Writing and drawing cartoons has long been a good outlet for me. It has helped keep me positive and focused (most of the time) for the nine years (so far) of my journey.

I had few expectations when I launched the blog (launched may be pretentious—mostly I chose a name and clicked on an icon).

·       I assumed not many people would read it—true, but the numbers are getting better.

·       I assumed it would be fun for me to do—true, and it has continued to be.

·       I assumed it wouldn’t make me rich or famous—true (so far) and I have no illusions of future fame or fortune.

·       I assumed there would be breakthroughs in cancer treatment—true, and that’s good news for me and a couple million other men.

My expectations have changed a little. With my slowly growing knowledge of Internet technology I found ways to share information with more people. I even know what tweet and text mean. So, in the near future here’s what’s going to happen:

·       My book, Real Men Get Prostate Cancer Too, is being updated (2nd Ed.) and will be republished soon. A lot has happened in the prostate cancer world (and mine) in four years. I even added some new cartoons.

·       My other book (sounds impressive, eh?) with co-author Dr. Tom Beer, Cancer Clinical Trials, will also be published soon.

Both books should be available by mid-April.

Some Days are “Less Better” Than Others

Or maybe it just seems that way

Is it better to know or not to know? That, of course, is part of the great PSA debate I’ve talked about before, but also a question for those of us who are five or 10 years down the prostate cancer pike.

For the past nine years I have had a PSA exam at least once every three months. After surgery it told me that they didn’t get it all. My PSA doubled every three months for the year after surgery. Then there was radiation therapy and the same thing happened. Two possible cures that weren’t...It happened and I adjusted.

Since then I have tried experimental drugs (Clinical Trial) and a bunch of hormone therapy drugs—pills and injections. My PSA has slowly gone up and slowly gone down—generally within the rather small range of 2.5 to 4.8. Not bad as far as I’m concerned. So when there was a bigger increase over a short period of time it was a bit unusual.

My last PSA jumped (almost doubled over six weeks) a bunch. It was already on the rise so I shouldn’t have been surprised (but of course I was). I know some meds work for years, some for months, and some not at all. I really did know that. I also know that there are more meds to try and surely one will bring my PSA back down and my comfort level back up.

Would I have been better off had I not known all those numbers? Would I have been more comfortable just assuming all was well? Not a chance. Ignorance is not bliss. What do you think?
