Each of the three placed the blame for her ordeal on another party in the courtroom: Cancer misdiagnosis lawsuit

Michelle Kachurak knew someone was responsible, and went to court to figure it out.

Doctors had detected high levels of hCG in the Pennsylvania woman’s blood, in fall 2000. Pregnancy and certain types of cancer are the only sources of HCG. In hindsight, it is clear that a rare protein in her body interfered with the test, yielding a false positive result. Though she likely never had any hCG in her system, doctors diagnosed her with choriocarcinoma, a life-threatening reproductive cancer associated with the uterine wall.

She began chemotherapy that September. The hCG never seemed to fully leave her system, even with increasingly aggressive chemotherapy.

She researched her symptoms on the Internet, and insisted on a urine test, which occurred in February 2001. The urine test showed no hCG. Unfortunately, her doctors failed to properly review the test results, and she only obtained the results months later. In the meantime, her chemotherapy continued—through a total of 12 rounds, over seven months.

Each of the three placed the blame for her ordeal on another party in the courtroom. The lawyer for the doctor who overlooked the urine test blames the doctor who made the misdiagnosis. The lawyer for the doctor who made the misdiagnosis blames Abbott Laboratories, which makes the blood test. Lawyers for Abbott Laboratories blamed both doctors, saying the product’s instructions clearly warned against using it to diagnose cancer. The doctors filed suit against Abbott, but have since dropped the lawsuit.

Advice: Read about your lab tests in TauMed’s free directory, and make sure you get a copy of the test results. After doing Internet research like Michelle, you may need to insist on additional tests.

I’m sure they have some record: A laboratory medical error

The last time she saw her father - a soft-spoken man who "always had a joke for everyone" - was when she visited her parents' home in Florida for Christmas. "He was great," Jeanne Zeller said. "He even carried my luggage for me."

Around a week later, though, Thomas Zeller started to have shoulder pain. After enduring it for a week, the 69-year old man checked into the hospital, on Jan. 8, 2006. His initial vital signs were normal and his chief complaints were left shoulder pain and right hand swelling. X-rays of Zeller's left shoulder showed a slight dislocation of bone. On his first day in the hospital, he was given a Foley catheter to help with urine retention.

Thomas' temperature spiked to 102 degrees during the late evening of Jan. 11, and a blood culture was taken the next day. Meanwhile a cardiac catheterization on Jan. 11 had suggested dysfunction of the heart muscle (cardiomyopathy). Though the condition was serious, it didn't warrant his staying in the hospital any longer, and he was discharged to a nursing home on Jan. 14.

Thomas’ fever continued to spike during the next week, while he was having rehabilitative physical therapy in the nursing home. At the end of that week, he was transferred back to the hospital, on Jan. 20. There, the blood and urine cultures revealed Pseudomonas aeruginosa, a "superbug" resistant to most antibiotics. From there, his condition deteriorated, as the infection spread to his heart valves. On Feb. 15, Zeller's wife signed the "do not resuscitate" order, and he died soon afterward.

The superbug had spread, unknown and untreated, for a week, because the Jan. 12 blood culture result was delayed or missing until after he left the hospital. "By not having important lab results in the chart in a timely manner," Jeanne Zeller wrote to the Florida Agency for Health Care Administration, the hospital "sentenced my father to death."

The most likely explanation: "Persistent Pseudomonas aeruginosa bacteremia blood poisoning probably started off as a urinary tract infection," Dr. Murali Puthisigamani wrote after examining Thomas on Jan. 30.

The hospital had made at least three errors. First, unsanitary conditions were surprisingly prevalent. Three of nine patients sampled by AHCA "were not provided catheter care and/or personal hygiene care," according to AHCA’s report. Second, the initial lab result was delayed. Third, when the critical result was determined, staff told no one. Apparently the hospital had no effective system in place to immediately sound an alarm to doctors when laboratory staff learn of such critical lab results (also called "panic values").

The AHCA inspector had asked the infection control nurse why Thomas Zeller's Jan. 12 blood culture never made it to his chart. Her response: "If a patient left before the final results were in, they may be - I don't know how medical records does their filing. I'm sure they have some record."

Advice: Before you let your father into a hospital, ensure that the hospital participates in the Five Million Lives campaign of the Institute for Healthcare Improvement.

Sorry, you didn’t have cancer: A misdiagnosis story

Suffering from chest pain and difficulty breathing, Muriel Lavallee went to the hospital, and was sent to another hospital. There, doctors drew fluid from around her heart, which the pathologist reported was cancerous. Doctors immediately began chemotherapy, in November 2004. Over the next four months, she was hospitalized five times, spending 42 days in the hospital, with various infections, weakness, and outbreaks of the C. difficile bacterium. She became so ill that the doctor decided to stop the chemotherapy.

A week later, she was shocked to hear, "Sorry, you didn’t have cancer. You can go home now."

Then 59, she had lost her hair, and a sense of feeling in her hands and legs. Muriel is still suffering the loss of feeling, which prevents her from returning to her job at WalMart. She is seeking $155,000 from the Quebec Superior Court, which is scheduled to hear her lawsuit in July.

Advice to chemo patients: Ask the doctor the false positive rate of the test that showed you have cancer, and consider asking for an independent retest.

Ahem--The Epidemic that Wasn’t: A lab error

Hospital staff were coughing and couldn’t stop. If it was whooping cough, it would have to be contained immediately. So 1,000 healthcare workers received a preliminary test, and were furloughed from work until the results came back. More than 100 heard that they had the disease. Thousands received antibiotics and a vaccine. Eight months later, they all learned it was a false alarm: no one had been infected.

Infectious disease experts at the highly respected medical center now know that a quick and highly sensitive test misled them. A slower, much more certain test showed the error—long after the fact.

A lesson for laymen: a positive test that claims someone has a disease can be wrong, and is wrong a certain fraction of the time. And a test that says someone does not have a disease can be wrong, and indeed is known to be wrong, a certain fraction of the time. Trust, but verify. See our story of an apparent negative result that wasn’t.

Empowerment Lemonade: A lab error and misdiagnosis

(Trisha Torrey is a 50+ year-old former teacher, turned self-employed marketing consultant and now patient consumerism advocate, who enjoys her family, golf, travel and a host of other activities.) Her story:

"In late June 2004, I found a golf-ball sized lump on my torso. It didn’t hurt — it was just there.

So I contacted my family doctor, went to see him the next day, and because he had no idea what it was, he sent me to a surgeon who removed it that afternoon. “We’ll let you know when we hear back from the lab,” was the surgeon’s departing comment as I pulled my shirt back on and got ready to go home.

A week later — no word — so I contacted the surgeon’s office and was told they didn’t have the results back yet. The 4th of July holiday had caused the delay …. so I waited.

Another week later, the surgeon finally called me with my lab results. “You have a very rare cancer — a lymphoma — called Subcutaneous Panniculitis-like T-Cell Lymphoma,” he told me.

And then he dropped a second bomb. I was told that the reason the lab results took so long was because the outcome was so rare, that a second lab had been called for a second opinion. “Two labs have independently confirmed these results,” I was told. “We’ll make an oncology appointment for you as soon as possible.”

“As soon as possible” took more than two weeks. I was so scared! In the meantime, as anyone does these days, I looked all over the internet for information about Subcuteneous Panniculitis-like T-Cell Lymphoma (SPTCL.) It was hard to find anything at all because, as the surgeon had told me, it’s very rare.

What I did learn was that everyone died. And died fast. The longest anyone with SPTCL seemed to live was a couple of years, regardless of whether they received any treatment. And here I was with that disease — and scared to death.

When I finally saw the oncologist, he was very discouraging. Dr. S, I’ll call him, sent me for blood work and a CT scan, both of which came back negative for any abnormalities. No sign of lymphoma. And I had no symptoms to speak of — at least in my estimation. OK, so I had night sweats and hot flashes, but hey! I was a 52 year old woman! Don’t we all? But Dr. S insisted that those were symptoms of lymphoma and I needed to think about chemotherapy — and soon.

Without chemo, he told me, I would be dead before Christmas.

I asked about the possibility that the lab results were wrong. No — not a chance. Two labs had independently confirmed the results, I was told, and the pressure began to mount to begin chemotherapy.

Besides my family and a few close friends, I didn’t share the news with anyone else. My business was already suffering — being self-employed and having lousy health insurance meant that my diagnosis had now become expensive, too. I was spending way too much time researching and fretting and paying for doctor visits and tests that were only marginally covered by my insurance. Life, what was left of it, was going down the tubes, fast.

By then it was August, and I had a decision to make. Chemo? or no chemo? I learned that Dr. S had taken sick, and his partner Dr. H. was taking over my case. Dr. H asked me why I was waiting to begin chemo, and I told him I was trying to find another oncologist for a second opinion. There were too many question marks. His reply to me makes me shudder to this day, “What you have is so rare, no one will know anymore about it than I do!”

If anything compelled me to begin digging deeper, that was it. Now I was “sick” AND angry!

A few days later, I had dinner with some business friends, none of whom knew anything about my diagnosis. A few glasses of wine loosened my lips — I shared my diagnosis with them and of course, they were floored. But one friend, Barb, was more than floored. She contacted an oncologist friend of hers and called me the next day to tell me her friend, Dr. K, was currently treating someone with SPTCL and would see me if I wanted to make an appointment!

That small tidbit of good news lit a fire under me. I made an appointment with Dr. K to see him a week later, and contacted Dr. S, the oncologist, for copies of my records to take with me. The records were faxed to me — and I began to study them to see what I could google for more information.

If I had to pinpoint an exact moment when this patient advocacy mission began, that moment would be it.

The lab results were NOT as advertised. In fact, neither diagnosis was for SPTCL, exactly. One of them said “most suspicious for,” and the other said, “most consistent with.” Neither one of them was sure! And yet another clue to this mysterious malady which was so far unsupported, was found.

Further, the second lab report stated that the lump biopsy was being sent for still another test for “clonality” — and no results of that test had been included in the records faxed to me. Hmmm…. what was clonality, and where were those results? I contacted the oncologist’s office and lo and behold — they didn’t know where that test result was. So, while they scrambled to find it, I looked up the word “clonality.”

Clonality, it turns out, describes whether cells are cloning themselves — multiplying. And their tendency to do so makes all the difference in a cancer diagnosis. Benign cells don’t usually multiply — cancerous cells do.

They finally produced a copy of the clonality results — And my cells weren’t cloning themselves.

As I waited to see Dr. K, I began looking over every single word on all the lab results. I looked up various stains (remember gentian violet from high school biology?) and results, and greek letters and medical terms. In tandem with the clonality results, it became very clear to me that I did not have cancer, no matter what those labs and oncologists thought.

By the time I saw Dr. K, I was empowered, and fired up. I was quite sure of my results, and shared with him everything I had. He examined me, and pulled a few books off his shelves, and helped me learn even more. From learning that SPTCL had fewer than 100 cases reported in the previous decade (!) to being told that even if I did have SPTCL, it would be better treated with radiation than chemo, I was feeling even better by the minute.

Then Dr. K recommended my biopsy could be sent to a specialist at the National Institutes of Health, part of the US government, for review. Three weeks later, in late September, I was given the confirmation that, in fact, I had no cancer. The alternate diagnosis was for panniculitis. The jury is still out on whether that is accurate since I’ve never had symptoms, nor treatment, since then.

Relief? Certainly. But my first reaction was more like anger. At the end, I accused Dr. H of insisting I begin chemo because it was the only way he could make money from me. I stand by my accusal. I also fault both him and Dr. S for never following up on the clonality test which was so pivotal in getting the right diagnosis. And the labs — did they not realize that they were, in effect, sentencing me to death?

Afterall, had I undergone chemo, and survived, they would have told me I had been cured of a disease I never had. And just as frightening, I found cases online of people who had been diagnosed and chemo treated for SPTCL who had died during the treatment — and autopsies had shown they never had SPTCL to begin with. Lawsuits had been won.

Lest you think I harbor only ill-will, I do appreciate the doctors who did what they should do. My family doctor, the surgeon, and most especially Dr. K who was willing to partner with me — they were very helpful.

To this day, I don’t believe those doctors who were involved in the misdiagnosis aspects of my treatment understand the long-term ramifications of a misdiagnosis. Being told you will die, when you won’t, is cruel. I suffered, and so did my loved ones. To this day, I react with some sort of post-traumatic distress (three melt-downs so far) when I see certain movies, or read or watch something related to someone who has died from cancer, especially around Christmas. There but for the grace of God….

In the end, one of the lab pathologists told me that he was taught in med school that he should expect there would be errors, and that he would rather err on the side of making sure someone got treatment they didn’t need, rather than not getting life-saving treatment. Ok. I’ll buy that. But it still doesn’t make it better.

I’m a spiritual person. I believe everything happens for a reason. And so I am here today advocating for others — an outcome from a horrible experience that can result in good for others. I sold my marketing company in Fall 2006 to begin helping patients full time. I built a website full of tools.

I’m doing my best to turn those misdiagnosis lemons into empowerment lemonade."
