NETest

Nancy Teixiera, a registered nurse and carcinoid patient, spoke to the New York Noids Support Group yesterday.  She is representing Wren Labs which is working with Clifton Life Sciences. Wren has developed a genetic marker specific to neuroendocrine tumors.  The test measures tumor activity at a cellular level. The NETest is a novel blood-based molecular diagnostic that provides highly sensitive and specific information with respect to tumor status and therapeutic efficacy. The test is unique in that it uses 51 neuroendocrine tumor- specific gene transcripts developed by Wren scientists. The NETest has been developed and validated in over 600 NET patients and can identify the presence and activity of NET cells circulating prior to the formation of metastatic tumor.  The idea is to have the test performed on a periodic basis and see if there is a trend.  The blood test is scaled on a 0 – 8 basis with the levels as follows:

Level 1-4:  low activity

Level 5-6:  medium activity
Level 7-8:  high activity

This NETest can pick up tumor activity unlike Chromogranin A and Pancreastatin which monitor secretion. The question that came up in the group was: What should one do with the information if the trend is upward?  If that were the case, one could work with their doctor to consider modifying current therapy. Examples could include, increasing the dose of Sandostatin, finding the tumor(s) and removing it or some other systemic therapy such as chemotherapy or Peptide Receptor Radionuclide Therapy (PRRT).  This test is individualized and therefore so is each patient’s management plan.

In order for patients and physicians to appreciate the benefit of trending values, the company has offered to give this blood test for free 3 times over a course of 9 months to each NET patient in the group.  This way, each patient would have a baseline to measure their tumor activity.  They have applied for a Current Procedural Terminology (CPT) code and anticipate having this in place by May, 2014. The procedure could then be covered by insurance before the 9 months of free testing is done.  Wren Labs is bringing this test to the attention of patients prior or simultaneously to informing doctors of it.  Nancy has been visiting support groups around the country to inform patients of the test, as well as having discussions with NETs specialists at various national conferences. 

I think the challenge is to get doctors to understand and utilize the test.  Just like anything, if the test shows high tumor activity and there is no good way of finding the tumors or correcting the problem, then what is the benefit of having this information?  This could cause anxiety for patients, which seemed to be a concern to some of the patients in the group.   A few of those in the group suggested that we all go together to Branford, CT, where Wren Labs is located to get the test done together.  It would be like a Noids field trip! 
I’m inclined to go ahead and get the blood test.  It is a very low risk procedure in that I don’t need to take any medications or get scanned and it could help others with this disease in the future.  We’ll see what happens. 

If anyone else would like to get the NETest, you can contact Nancy Teixeira at nancy@wrenlaboratories.com

A Bump in the Recovery Road

I am now nearly 5 months post-surgery and things have been going reasonably well.  I am back to work but don’t have nearly the stamina I had pre-surgery.  After 5 days of working, I am very tired.  In the past month, I’ve had 2 incidences of severe abdominal pain.  It starts feeling like I was kicked in the stomach, then goes into severe pain with what feels like contractions or spasms.  The first time it happened, it was on a Friday night and I took a tramadol (pain killer). That helped me to sleep and I felt fine in the morning.  The second time was on Super Bowl Sunday and no, I was not eating tons of fatty foods and drinking beer!  It started the same way with the kicked in the stomach feeling, then went to contractions.  I did not take a tramadol until after the Super Bowl ended because I was trying to watch it.  I did take the tramadol around 10:30 pm but that time it did not help me get to sleep.  At about 3:00 am, I was vomiting and still in severe pain.  The next morning I went in to see my primary care physician and he said that I might have had my bowel kink and then unkink – that can cause this type of pain.  He said he did not think that I was having an obstruction at that time and if I were, I would be quite bloated.  I started to feel better later in the day on Monday.  I messaged my oncologist and she said that the nurse practitioner would talk to me about it when I came in on Thursday February 13th

At my appointment, the nurse practitioner explained that this type of pain can come from a bowel surgery.  She said it could have been a “kinked bowel” or partial obstruction but did not know for sure.  She said that if it happens again, I should get to a radiology facility and get a KUB which stands for kidney, ureter, bladder.  A KUB is an x-ray of the chest and lower abdomen and is used to detect bowel obstructions.  I didn’t get the impression that even if they knew exactly what the problem was, that there was a good solution for it.  Nonetheless, I’ll ask my primary care physician how I might get a KUB quickly, should I need one.  I would prefer not to go to the emergency room because the wait would be long and who knows what else they would do besides a KUB.  Anyway, this really threw me off as I have had a pretty painless recuperation until now.  I’ve already used two sick days for abdominal issues and at this rate I’ll be out of days well before year-end.  I’m hoping this doesn’t happen again but I don’t know what I can do to avoid it or mitigate the pain since I don’t know exactly what is going on.  Some other patients have suggested taking fish oil or drinking coke syrup when it starts to hurt.  I asked the nurse practitioner about this and she said that she had not heard that these things work but there is no harm it trying it if I want to. 

Because of these abdominal issues and the fact that I was not eating much for a day or two after each event, I lost another 2+ pounds this month.  I was hoping to get my weight stabilized to I could figure out what size I will be but now my “new” clothes are getting a bit loose on me.  Oh well, that is a minor issue relative to the pain.  I’m hoping that this is not going to be a recurring problem.

We Are Giving Ourselves Cancer

In yesterday’s New York Times, there was an editorial with the title above. The subject was the extensive use of CT scans and how we are “silently irradiating ourselves to death”.  The Op-Ed was written by two doctors at San Francisco Medical Center.  It generated a lot of comments, most of which were directed at the lack of clinical evidence regarding their theory. Nonetheless, this subject is near and dear to my heart as a cancer patient who undergoes a CT scan at least every 6 months.  Since my diagnosis in August 2010, I have had 8 CT scans!  My concern is that the radiation from CT scans can cause cancer.  My question is: What if you already have cancer?  I’m trying to understand the risk of missing something by not doing regular CT scans versus the risk of getting another type of cancer from all the radiation.  I’ve spoken with my oncologist about the frequency of my CT scans since I have been concerned about this for a while.  She said that if there were no cancer, we would not be doing CT scans but since I do have cancer, the CT scans are appropriate to monitor for changes.  I really do not know how to evaluate my risks; i.e., is the risk of radiation from the CT scan higher or lower than the risk of not catching cancer progression in time if we spaced the CTs farther apart?  Would an ultrasound or MRI be a better way to measure progression?  My doctor says an MRI would be better for liver tumors but not for other abdominal lesions.  Perhaps less frequent CT scans would be an appropriate approach?

The link to the NYT editorial is below:
http://www.nytimes.com/2014/01/31/opinion/we-are-giving-ourselves-cancer.html?_r=0

One of the ACOR list members posted an X-ray risk calculator that can give one an idea of their exposure to radiation and their additional cancer risk.  You can access the calculator at http://www.xrayrisk.com/.  I have no idea how credible this source is in evaluating radiation risk but it at least gives me a “radiology risk budget” and helps me to quantify the risk.   I put in my CT scans, 68-GA PET, mammograms and other radiological tests but not my dental x-rays and the small bowel x-ray series and came up with the results below.  My additional cancer risk from the tests I’ve already had is 1 in 84 or a 98.8% chance of having no effect from this exposure.  Again, I have no idea how accurate this calculator is but given this information, and my current stage 4 cancer diagnosis, I’d say it’s ok to keep doing CT’s. Perhaps the NYT editorial was overly alarmist?  Am I overthinking this whole subject?  I’d be interested in what others think about these risks.

How Long Have I Got Left?

Interesting opinion by a doctor diagnosed with cancer in today's New York Times.  He writes about longevity discussions and how he's dealing with  his own mortality.

I have had the same conversations with my doctors with similar answers.  It's hard when your own mortality is front and center. I think it's important to enjoy life, stop worrying and do the best you can with this new information.  Easier said than done though....

Controversial Dual Editorials about Cancer Care

Last week, Emma and Bill Keller, both writers, she for Britain’s The Guardian and he for The New York Times, wrote editorials for their respective papers about how much detail one should divulge publicly when dying of cancer. Ms. Keller’s op-ed was published on January 8th and it was titled “Forget funeral selfies. What are the ethics of tweeting a terminal illness?”  She specifically describes the blog and tweets of Lisa Bonchek Adams, a 44 year old stage 4 cancer patient who is married with 3 children and is writing an “unsparing narrative” of her cancer treatments and journey towards death. Some excerpts from the editorial follow:

“Adams is dying out loud”
“As her condition declined, her tweets amped up both in frequency and intensity. I couldn't stop reading…but I felt embarrassed at my voyeurism. Should there be boundaries in this kind of experience? Is there such a thing as TMI? Are her tweets a grim equivalent of deathbed selfies, one step further than funeral selfies? Why am I so obsessed?”
“She describes a fantastic set up at Sloan-Kettering, where she can order what she wants to eat at any time of day or night and get as much pain medication as she needs from a dedicated and compassionate "team", but there is no mention of the cost.”
The snarky tone of this editorial generated a lot of outraged response in The Guardian.  In addition, Emma Keller has had email and twitter communications with Lisa Bonchek Adams but did not disclose to her that she would be using the content of those communications in an article.  Because of this journalistic transgression, The Guardian withdrew her editorial from the website.  Below is an archived copy of the piece:
Because of the outrage and in defense of his wife’s editorial, Bill Keller penned an op-ed in The New York Times on Monday January 13 called “Heroic Measures”.  This editorial is not quite as critical as Emma’s but also generated quite of lot of outrage.  At least the NYT did not remove it from their website.  Here are a few points from Mr. Keller’s editorial:
“A rapt audience of several thousand follows her unsparing narrative of mastectomy, chemotherapy, radiation, biopsies and scans, pumps and drains and catheters, grueling drug trials and grim side effects, along with her posts on how to tell the children, potshots at the breast cancer lobby, poetry and resolute calls to “persevere.”
“In October 2012 I wrote about my father-in-law’s death from cancer in a British hospital. There, more routinely than in the United States, patients are offered the option of being unplugged from everything except pain killers and allowed to slip peacefully from life. His death seemed to me a humane and honorable alternative to the frantic medical trench warfare that often makes an expensive misery of death in America."
“Lisa Adams’s choice is in a sense the opposite. Her aim was to buy as much time as possible to watch her three children grow up. So she is all about heroic measures.”
“The first thing I would say is that her decision to treat her terminal disease as a military campaign has worked for her. Her relationship with the hospital provides her with intensive, premium medical care, including not just constant maintenance and aggressive treatment but such Sloan-Kettering amenities as the Caring Canines program, in which patients get a playful cuddle with visiting dogs.”
“In any case, I cannot imagine Lisa Adams reaching a point where resistance gives way to acceptance. That is entirely her choice, and deserving of our respect."
Below is a link to Bill Keller’s editorial:
I found these two editorials quite interesting.  Aside from the controversy and publicity that this writing generated, they raise important questions about privacy, discussion of death, whether cancer is a battle or a disease, the cost of treatment and how hospitals might benefit from patients who are in the public domain.  Amy Bonchek Adams had to know that these two writers were going to write about her cancer, blog and tweets because they were both communicating with her prior to the publication of these pieces.   I was uncomfortable with the tone of Emma Keller’s editorial but not so much with Bill's attempt at clarification.  I do not believe that blogging and tweeting about cancer is “too much information (TMI)”.  If one doesn’t want to read it, they don’t have to. It’s up to the patient to decide if she/he wants to fight with debilitating treatments until they die or if they want to die quietly without them.  I have been impressed with the NYT’s bringing articles to the forefront on many facets of cancer, sometimes quite prominently.  These conversations need to be more public.

First Post-Surgical CT Scan

Yesterday I had my first post-surgical CT scan.  This is described on the report as a “restaging” scan.  Dr. Chan showed me the before and after scans. There are a lot fewer white areas or tumors now.  The only impression that was in the report was “mild associated mesenteric fat stranding and nodularity is noted, likely postsurgical in etiology”.  Dr. Chan said this is because I have not fully healed from the surgery as it was only 4 months ago.  I’m not really sure exactly what “fat stranding” is and after googling it, I’m still in the dark.  As long as the doctor is not too concerned, neither am I.  The remaining few small tumors in my liver stayed unchanged. 

I am mostly recovered from my surgery but I still do have some lingering gastrointestinal stress.  This can manifest itself in very bad gas pains, both in my chest and abdominal area.  I have not identified a particular food or time of day that could be the cause of this discomfort.  Sometime it lasts for 5-6 hours before going away.  I occasionally have massive diarrhea, similar to a colonoscopy prep that is quite disruptive and disturbing.   I had this twice in December. I know the first time was because I ate too much fatty food, but the other time I did not so couldn’t identify the cause.  I have not had the really bad diarrhea in January yet so hopefully that problem has passed.   Dr. Chan suggested I try Prilosec this month to see if it alleviates the gas problem. 
All in all, I’m doing ok and today marks my new CT baseline.

Why Everyone Seems to Have Cancer

This is the headline article (Op-Ed) in today’s Sunday Review section of The New York Times (NYT).  It is written by a former NYT reporter and author of a book called The Cancer Chronicles that was well reviewed a few months ago.  I have not read the book.  The author discusses why heart disease deaths have declined substantially from 38 deaths per 10,000 people in 1958 to 18 deaths per 10,000 people in 2010. Concurrently, cancer deaths at 19 per 10,000 in 1958 have only declined to 17 per 10,000 in 2010.  The basic premise of the article is that “heart disease and cancer are primarily diseases of aging.  Fewer people succumbing to one means more people living long enough to die from the other”.  He explains that deaths from heart disease have declined due to “diet, exercise and medicines for blood pressure and cholesterol.  When problems arise, they can often be treated as mechanical problems – clogged piping, worn-out valves – for which there may be a temporary fix”. “Because of these interventions, people between the ages of 55 and 84 are increasingly likely to die from cancer than heart disease.  The increase in longevity has been why the statistics show more cancer deaths.  “A century ago, average life expectancy was in the low to mid-50’s.  Now it is almost 79. The median age of cancer death is 72”.  There is a very interesting graphic that illustrates these statistics – it is in the link below:

The author is pessimistic about a cure for cancer. “It is not so much a disease as a phenomenon, the result of a basic evolutionary compromise. As a body lives and grows, its cells are constantly dividing, copying their DNA — this vast genetic library — and bequeathing it to the daughter cells. They in turn pass it to their own progeny: copies of copies of copies. Along the way, errors inevitably occur. Some are caused by carcinogens but most are random misprints.”   He says that most of the improvement in cancer longevity statistics comes from prevention and from improvements in mortality from childhood cancers.  The author goes on to say “for most cancers the only identifiable cause is entropy, the random genetic mutations that are an inevitable part of multicellular life.” 

The full article is in the link below:
This is a realistic article that does not give false hope about an imminent cure for cancer.  Interesting reading.
