The Experts are Wrong (Sometimes)

“It's another fact of cancer that the more informed and empowered patient has a better chance of long-term survival.”     Lance Armstrong

I’m by no means an expert in cancer diagnosis, but I’ve learned a few things from the experts and the so-called experts in the past year that have helped me avoid costly, perhaps life threatening mistakes. I feel that it is important to share these, because the most important lessons – as they often are in life – are the ones they do not put in books or brochures outside the doctor’s office.  So sit back and join me on a journey through my diagnosis experience and see the lessons I have learned.  They can literally save your life.

Experts have a hard time seeing beyond the focus of their expertise.
Many of the lessons I’ve learned deal with the fact that I am not, in medical terms, an “expert” and those that are considered experts are not always the right experts.  This can sometimes be because of the question that you - the patient – are asking, either implicitly or explicitly.  When I was starting to have mysterious black eyes on my right side I went immediately to an optometrist and then to an ophthalmologist.  I was already assuming, implicitly by my selection of specialist, that something was wrong with my eye.  These experts correctly told me that there was nothing wrong with my eye.  They incorrectly told me that everything was probably OK, that my symptoms were some temporary isolated trauma that would go away soon. I took only their expert opinion about my eye and disregarded their other conclusion, as I knew it was an assumption beyond their expertise.  The black eyes continued so I was right to disregard their sweeping statements of my good health.

Generalists can have a hard time looking beyond the obvious.
Assuming that my actual eye was OK I then went to my generalist doctor to see if there was something else that would explain the black eyes.  He agreed with the specialist that it was some kind of local trauma and that the big picture – my excellent overall health – led him to believe that there was nothing wrong with me.  He went further to posit a theory that I was punching myself in my sleep or sleeping on a closed hand that caused the trauma.  Perhaps my wife was beating me after I passed out from drinking too much?  He even offered a personal story from his boyhood as evidence of this possibility.  I asked specifically if there was something inside my head that could cause the black eyes.  I asked if I needed some kind of brain scan.  He vehemently claimed that it was impossible for something in the head to cause bleeding on the face – the head was just not made this way.  His assumptions and conclusions were all wrong.

If you do not like the answers you are getting, then examine the questions you are asking.
Still looking for answers I figured I needed a different kind of expert, one on the area around the eye and not one that just looked at the condition of the eye itself.  I had no idea what kind of expert that would be and asked my kid’s optometrist.  He recommended an ophthalmological surgeon who would have the expertise of the whole eye structure - the orbit – that contains the eyeball as well as optic nerves, etc.  I stumbled across a brilliant doctor in Boca Raton by looking for the eye doctor office with the most number of doctors and ad space in the phone book.  Most of these do cosmetic surgery, but they would have the right frame of reference I was looking for.  Immediately in my first meeting with him he assumed there was something behind my eye and ordered an MRI that plainly showed the growing tumor there.  I think he was brilliant because even though he could not immediately come up with a reason that an orbit tumor could cause the black eye, he went with what his analysis was telling him.  He was surprisingly honest and open with me about this.  He did later came up with a theory that the tumor was rubbing the walls of the orbit , rupturing small blood vessels that leaked blood into my face under the right eye causing the black eyes.  Brilliant.

Even world-class experts have a hard time seeing beyond the focus of their expertise.
I was referred to the best orbit surgeon in the US to deal with the tumor.  He treated me for what he assumed was a cavernous hemangioma (basically a knotting of blood vessels) in my right orbit.  He planned surgery after waiting two months for the blood to clear up in the orbit.  He never once brought up the idea that it was something else, a cancer tumor perhaps, even though his staff had my previous melanoma history.  I believe the disconnect of giving my history to his staff and then only listening to his opinion in the few minutes allotted to me allowed this mistake to happen and is a potential downside of large teaching hospitals.  I should have asked this question but I did not.  I should have insisted on a biopsy and I should have sought a second opinion, but I did not.  When I developed a skull lesion he continued with his treatment protocol.  Even when, the Friday before my scheduled Tuesday eye surgery, a PET scan showed I had metastatic melanoma throughout my body, he still believed the evidence suggested it was a hemangioma and not a cancer metastasis.  Was he covering his ass or just being stubborn?  I learned from this the medical theory of unified diagnosis, which says you look for the diagnosis that explains as much of the problem as possible.  The possibility that the eye tumor was a hemangioma while all my other tumors were metastasis was not unified.  But he was an eye surgeon focused on removing the thing in my orbit and he was not looking for the reason why it was there.  I made some mistakes here but thankfully it only cost me a couple months of diagnosis.  Lesson learned.

Finding the right type of doctor does not mean you’ve found the right doctor.
My first oncologist was very unpleasant, but I know that an asshole doctor can also be a brilliant doctor so I stuck with him through my initial staging process.  I found him after searching for the doctor at the regional cancer center that was most published, most involved in research and best known.  He was indeed the expert on melanoma at that cancer center and I was fortunate to get an appointment with him, or so I thought.  In his brusque manner he examined my PET scan and said I had to choose from one of four treatment options, with just a few sentences of explanation of each.  He urged me to make a decision quickly, and even called a couple of times over the next week asking what my decision was.  The options were all standard treatments with 0-15% response rates – chemo, high dose IL2, BRAF and Yervoy.  He did not mention any of the other options out there, and although he was familiar with the t-cell therapy he said I was not a candidate because my tumors were not large enough to harvest.  This was absolutely wrong, and the treatments he offered were standard and did not take anything into consideration about my specific health and condition.  Indeed, he did not ask anything about my current health or general medical history.  And when I told him I wanted an opinion from MD Anderson he said his cancer center could offer anything MD Anderson could.  Wrong, wrong, wrong.  I walked out of his office and never went back.  Another doctor I know, when told about this, asked me what you call the person that graduated last in their class at medical school?  “Doctor.”

Experts can be right and wrong at the same time.
My third opinion came from a well-known oncologist in Florida who was one of the nicest doctors I’ve met in my journey so far.  He was very generous with his time and was very willing to argue the merits of different treatment protocols, but I believe he was wrong in his conclusions.  Who am I to question a well-known oncology expert?  Case in point, he said that biochemo treatment was proven academically as ineffective and that he had personal experience with the failure of the treatment to cure his patients.  He asked me not to go through with it at MD Anderson.  This really perplexed me and I dove into the scientific data for answers.  I read many medical journals, often putting a “Dr.” in front of my name to get a trial subscription to the expensive ones.  What did I find?  After biochemo was first introduced and began making headlines it was rolled out across the country.  A study of the resultant experience with biochemo found that the earlier stated results of 30%+ response rates were not being replicated and the toxic side effects were much more difficult to patients than earlier studies had stated.  So the doctor was right?  No.  I also found a later study of this study’s results which showed that the treatment in the medical centers where there was biohemo expertise (Angeles, MD Anderson, etc. ) remained successful.  The conclusion was that the expert staff at these centers – doctors and nurses with special training and experience with the protocol - could better help patients handle the side effects of the toxic treatment which allowed the patients to get higher doses that lead to higher results.  Your local cancer treatment center could not achieve the higher doses as patients developed problems with the toxicity and therefore had the lower results.  There is still controversy about this – I believe stemming from some kind of institutional inferiority complex of many regional cancer centers - but it made sense to me.  It explained how he could be right and wrong and the same time.  Additionally, I made an estimation of the demographics of this doctor’s practice which lead me to assume that most of his patients were elderly as it seemed to treat the large retirement population where it was located.  He probably rarely had the healthy patient like me looking for rigorous treatment.  His cancer treatment experience and expertise did not match my needs.  He was right, but not right for me.
    
     I’m not saying that I am not still making mistakes, but I always question assumptions – others and mine.  The experience of cancer diagnosis is a scary one, more so than the actual treatment protocols.  I've heard it described as being transported to another country.  One day you are making coffee before work, taking your kids to school and planning your weekend.  The next day after diagnosis you are alone in a foreign land where everybody speaks a different language.  There are many people willing to help you, offering to show you the way home.  But the path home is painted in the art of self reliance.  That is the current state of cancer care, like it or not.
     Cancer is not going to get an easy break from a misinformed doctor.  Not with me. Not now. Not ever.

The Big Guns and the God of Thunder

OK, so it is time to bring out the big guns for this fight with cancer.  I mentioned the TIL clinical trial before and I've gotten a lot of questions about it.  On the right side and down a bit are permanent links to the study details and a great article about the process and Dr. Steven Rosenberg at the National Cancer Institute that developed it.  Dr. Hwu at MD Anderson used to be at NCI and brought the study with him to Texas.  The article in particular does the research work more justice than I can do here, but I'll give it a college try.  The TIL study utilizes adoptive cell therapy (ACT) which is also call T-cell therapy.  The acronym TIL stands for tumor infiltrating lymphocytes, my personal favorite because it sounds like a covert special operations military unit led by Steven Seagal.  My understanding is that in every melanoma tumor lesion there are some immune cells trying to do the job.  They are in the tumor but obviously they are not doing a good enough job because the tumor is growing, and that if we could reinforce these t-cells the body can successfully beat back the cancer.  The process developed at NCI involves removing some tumors and extracting these t-cells from within them and then growing the t-cells in vitro in a lab.  Then, to prepare the body for the new t-cells, they wipe out the body's entire immune system (lympho depletion) and replace it with the new t-cells.  The result is a cancer patient with a new immune system specifically trained to fight melanoma, and that immune system will fight that cancer for the rest of its life.  The durable results are over 50%, which is amazing compared to the other standard treatments that have a 5-15% response rate.  Many researchers believe this is the future of fighting cancer, even a potential cure, but up to now very few people have undergone the treatment (about 95 at NCI, 45 at MD Anderson and some others at a research center in Israel).  The reason so few have undergone the treatment, and that the clinical trial has not moved on from Stage 2, is that the patient needs to have an accessible tumor, t-cells that will grow in the lab and be strong enough to handle the tough treatment.  The list of health factors required to be considered for the study is 23 items long with 8 exclusionary criteria.  These criteria eliminate four of five potential candidates.  Fortunately for me, I meet all of those.  The treatment is also terribly expensive and is currently being undertaken at only the three research centers mentioned.
     My treatment at MD Anderson will start with seven days of lympho depletion with chemo therapy (fludarabine and cytoxan).  I'll be in sort of an isolation setting, we don't want anyone sneezing on me at this stage.  The lympho depletion is is supposed to be easier than the biochemo protocol I already underwent and Dr. Patel is even working on getting a stationary bike into my treatment room for that phase (her estimation of my constitution is refreshing).  Then, they'll grow the t-cells from the existing frozen millions into the billions in a special laboratory in Houston.  On Day 0 they reintroduce the cells into my body.  Then up to a week of consecutive high-dose interleukin (IL2) treatments, a biologic drug that will kick-start my new immune system into high gear and help my body to start utilizing the t-cells.  This has similar side effects as biochemo and is no picnic.  Low dose IL2 was a not to pleasant part of the cocktail in the biochemo I've already gone through so I'm sure high dose IL2 is even more fun.  They want to give me as many high dose IL2 treatments as I can stand (specifically what my liver and heart can stand) up to 15 doses,  most patients get 5-10 doses.  I told the docs to give me 15 even if I am unconscious to which they smiled as if to a child asking to go to the moon, but I think a little bravado - however unwarranted - goes a long way in reinforcing my commitment to this treatment.  I'll spend a few days to a week recovering in the hospital and then I'll go home for a couple weeks.  Then I go back to Texas and we do the high dose IL2 treatment a second time.  And then we wait, because the new immune system will take time to seek out and destroy the cancer.  The next scans will be in six and twelve weeks after the "birth" of my new immune system where we’ll see if there is any progress.  It may take many months before we start seeing results.  It is interesting that my new immune system will be the same as a newborn's and I'll lose all my existing immunities that I've worked so hard to develop.  That means next year I'll need measles, mumps and chicken pox inoculations.  It will be interesting to be sitting in the pediatric office waiting room next year with a bunch of toddlers.
     I believe cycling, and very often professional bike racing, to be an accurate metaphor for so many things that happen in life.  In Stage 3 of this year's Tour de France Tyler Farrar, the best sprinter America has ever produced, looked like a possible to win the stage.  It was also July 4th and for an American on an American team to win the stage that day would be a phenomenal achievement.  However, the odds were long and Tyler faced many stronger and faster foes also fighting for the stage.  The racing had been touchy and a tour-ending, or even career-ending, crash was a definite possibility.  On Tyler's team is Thor Hushvold, the Norwegian "god of thunder" who was wearing the yellow jersey as the overall race leader in the Tour de France.  Thor also wears the rainbow jersey signifying that he is the current reigning world champion road racer.  Coming in together to the hectic last half kilometer of the stage, Thor jumped through a blind corner towing Tyler to the front of the nervous pack.  I've never seen a yellow jersey lead out a sprinter at a Tour de France but Thor is like that, a team player confident of his world-best skills and always willing to jump after any potential victory.  After Thor gave it his all he pulled over and let Tyler go on to sprint the final meters against his foes to win the biggest stage victory of his life.  You can see Thor smiling in this picture, resplendent in his yellow jersey, a few riders back from Tyler.  In many ways MD Anderson, and Dr. Patel, is my yellow jersey teammate leading me into the final section of the most important race of my life.  They are world champions in fighting cancer and they go aggressively after any possibility of victory.  And I know that they can get me close - closer than anyone else - but it is critical to remember that victory will require me to sprint the final meters alone and I know this will take everything I have.  But I also know that cancer will not beat me to the line, cannot beat me to the line,  when I have a world champion leading me into the finish.

Scan Results


Well, we got the results yesterday of Thursdays CT and MRIs and we got neither a winning lottery ticket nor devastating news - something more in the middle and along the lines of our original treatment plan.  The biochemo did not shrink my existing tumors but they also did not grow.  The tumor in my hip looks stable enough that Dr. Patel approved a stationary bike for me, which is pretty exciting.  Unfortunately, we did find two new tumors near my kidney.  Sometimes they call biochemo a "springboard treatment" specifically because it halts the progress of your existing cancer while you have to wait for other treatment options.  For us, we've waited five weeks for our other treatment option – the TIL study - and the t-cells they extracted from me in May have grown successfully into the millions.  This means that I can likely enter the TIL clinical trial at the end of July.  More details on what's involved in that later.
     So, what does this news mean?  Its some cold comfort that this was the plan from day one.  The TIL study was my number one goal and the reason we went to MD Anderson, but we did not get the sudden success from the biochemo that we held as an outside hope.  Our recent optimism was born of my surprisingly strong recovery from the biochemo.  We were made to expect to limp through the time in between treatments, to expect blood transfusions and emergency room visits, but my recovery was rapid and complete.  Now, two weeks after my second round - which was supposed to be the worst - I feel the best I have since entering treatment.  I even hit the hotel gym before seeing Dr. Patel yesterday.  I do not think my stamina was working in the same direction as the biochemo treatment.  Chemo works by destroying you - hoping that the healthy part of you is destroyed a little less than the cancer part of you.  The TIL treatment, however, relies on your body’s ability to fight, to recover and to attack that which attacks it.  This treatment seems to play into my strengths.
    Switching to the TIL treatment has many other positives.  In addition to having a complete attack plan, it means that I'll be spending a wonderful bonus time at home with the family while I'm feeling good.  It also means I may return to work after recovering from the second IL2 treatment and that I can resume a relatively normal life until otherwise notified.  This is all good news but delivered with a bit of a setback.  Lance said that cancer taught him to be comfortable with ambiguity, now I know what he's talking about.
     So this week we're going to take the kids to Disney World and enjoy the downtime before the big attack in a couple of weeks.  I'll continue regaining my stamina and getting stronger and healthier each and every day.  Meanwhile, cancer can sit there and wait, nervously anticipating the billions of specially trained tumor infiltrating lymphocytes that are coming its way soon.  Think about how many zeros are in a billion, cancer, and I'll be enjoying the Magic Kingdom.
