For Cancer-Detecting Canines, The Nose Knows

Share

A new clinical trial is set to begin in the United Kingdom using the powerful noses of dogs to detect prostate cancer in humans.

Dr. Claire Guest
Dr. Claire Guest, co-founder of Medical Detection Dogs, says one of her dogs sniffed out her own breast cancer.

While research has been done before, these are the first trials approved by Britain’s National Health Service.

The trials, at the Milton Keynes University Hospital in Buckinghamshire, will use animals from a nonprofit organization called Medical Detection Dogs, co-founded in 2008 by behavioral psychologist Claire Guest.

“What we’ve now discovered is that lots of diseases and conditions — and cancer included — that they actually have different volatile organic compounds, these smelly compounds, that are associated with them,” Guest tells NPR’s Rachel Martin. “And dogs can smell them.”

The dogs offer an inexpensive, noninvasive method to accompany the existing blood tests for prostate cancer, which detect prostate-specific antigen, or PSA, Guest says.

“It’s a low false-negative but a very high false-positive, meaning that 3 out of 4 men that have a raised PSA haven’t got cancer,” she explains. “So the physician has a very difficult decision to make: Which of the four men does he biopsy? What we want to do is provide an additional test — not a test that stands alone but an additional test that runs alongside the current testing, which a physician can use as part of that patient’s picture.”

The samples come to the dogs — the dogs never go to the patient. At the moment, our dogs would be screening about between a 0.5- to 1-ml drop of urine [or 1/5 to 1/10 teaspoon], so a very small amount. In the early days, of course, we know whether the samples have come from a patient with cancer or if the patient has another disease or condition, or is in fact healthy.

They come to the dogs at our training facility. They’re put into a carousel, and the dogs go around smelling samples. If they come across a sample that has a cancer smell, they’ll stop and stare at the sample and wait. They won’t move on.

On dogs’ sense of smell

Dogs, as we know, have got this fantastic sense of smell. They’ve got 300 million sense receptors in their nose — us humans have a sort of poor 5 million. So they are fantastic at smelling odors at very, very low levels.

On how a dog detected Guest’s own breast cancer

I had a dog who was — and still is — our most reliable prostate cancer detector dog. She was working on a project with me, but she started for a short time to be a little bit anxious around me, and one day kept jumping and staring at me and nudging into my chest. I found a lump which I hadn’t been aware of.

I sought medical advice. Actually, that particular lump was fine, but I had very, very deep-seated breast cancer. I had surgery and treatment, and I’m glad to say I’m fully recovered.

But it happened at a time when there was a huge amount of skepticism about whether dogs could in fact add anything the future of the diagnosis of cancer. It kept me focused on the fact that I knew that dogs could offer something, if we can diagnose for cancer by screening noninvasively, screening for volatiles. And of course, this could save thousands of lives in the future.

Jimmy Carter, full of grace

Former president Jimmy Carter
Former president Jimmy Carter

By Margery Eagan

Few Americans would call Jimmy Carter a model president.

But yesterday he offered us a model for facing where we’re all heading: death.

“I’m perfectly at ease with whatever comes,” he told news media yesterday in Atlanta, discussing for 40 minutes, frankly and often even jovially, his terminal cancer diagnosis. “I do have a deep religious faith, which I’m very grateful for.”

Doctors now believe new treatments could prolong his life. But even when he believed he had just a few weeks to live, Carter, 90, said, “I didn’t go into an attitude of much despair or anger or anything like that … I was just completely at ease.”

He called what’s next for him “a new adventure,” and said of his future, “Now I feel that it’s in the hands of God.”

In many ways, Carter’s press conference was typical of one of most extraordinary post-presidential careers ever: gracious, honest, humorous, and humble. Yet Carter, post-presidency, has written almost 30 books, including one on “The Virtues of Aging” and another called “Living Faith.” He spoke yesterday at the Carter Center, the nonprofit he began in 1982 to deal with global democracy and disease. One disease he mentioned is Guinea worm. The center maintains it has helped reduce it from millions of cases in Asia and Africa in the mid-1980s to just 126 cases last year. Not satisfied,  Carter quipped, “I’d like the last Guinea worm to die before I do.”

He has also worked tirelessly for women’s rights and equality. Last month, he said Jesus would support gay marriage. Habitat for Humanity, a nonprofit that builds housing for the poor, has been another central cause. Carter said he hopes to be well enough to travel with the organization Nepal in the fall. Meanwhile, he plans to teach his regular Sunday school class this weekend.

Carter also said that President Obama, former presidents George Bush and Bill Clinton, Vice President Joe Biden, and Secretary of State John Kerry have all called him to wish him well. Then he added, laughing, with characteristic humility, that it was the “first time they’ve called me in a long time.”

The verse from Micah 6:8 comes so quickly to mind about the sum of a great man’s life:

What does the Lord require of you but to do justice, and to love kindness, and to walk humbly with your God?

Whose Job Is It to Talk to Patients About Death?

Share

In the U.S. health-care system, it’s often unclear who should talk to patients about end-of-life care options. Medicare’s new reimbursement scheme may incentivize doctors to take ownership of those difficult conversations.

talking to a patient about death

By Ricardo Nuila

When Pedro Faust Tzul Menchu, a 45-year-old man with colon cancer, told his oncologist he couldn’t move his leg, a medical alarm bell went off. He’d received chemotherapy a week before, so his other symptoms of vomiting and jaundice weren’t entirely surprising. But the lack of movement in his legs could have been a sign of a spinal-cord compression—when an infection or tumor strangles the nerves running up and down the spine—and potential cord compressions are always treated as an emergency. Pedro was sent straight from the oncology clinic to the hospital, where he was assigned to me as a patient. As Pedro’s hospitalist, the doctor in charge of orchestrating his care, my main job was to figure out if his spinal cord was at risk.

An MRI showed that the cancer had spread to Pedro’s tailbone and throughout his abdomen, but hadn’t damaged his spinal cord. All the specialists I consulted—neurosurgeons, interventional radiologists, more oncologists—recommended a small procedure to protect the collapsed vertebrae so that a future spinal-cord compression might be avoided. When the weekend was over, I handed off Pedro’s care to a partner of mine, another hospitalist, since we typically rotate on Mondays. “They’ll perform the procedure this coming week,” I explained before leaving. Pedro sat up in bed, shook my hand, and thanked me.

Only later did I realize that I never told Pedro how close he now was to dying. His cancer had spread despite two lines of chemotherapy, a previous “debulking” surgery to remove as much of the tumor as possible, and constant surveillance with CT scans. It had nearly claimed the use of his legs. Most likely, it would claim his life within the next six months.

During our first meeting in the hospital’s cancer ward, Pedro confided to me how happy he was to have a doctor who spoke to him in his native Spanish. “It feels so good to be understood,” he said. “Hopefully, with God’s help, you’ll find a way to help me.” We didn’t only talk about his spinal cord. Every time I checked on him, we chatted about his old life in Guatemala.

A couple of times, Pedro arranged it so that his family visited while I made rounds, so I could talk to them all together about the steps that lay ahead. “I’m sorry, but it looks like the cancer has grown,” I told them. I mentioned the upcoming procedures, the possibility of radiation therapy, how the oncologist was considering a third line of chemotherapy, but I admit I never fully connected the dots for them. Telling him what this all meant, how it was almost certain that he would die sooner than he thought, proved too difficult. Like any good doctor, I know how to keep patients focused on the positives—“your family’s all here,” or “it’s good to see you sitting up”—while respecting reality. But something about Pedro, with his calm smile and earnest pleas for my help, made it more difficult than usual to summon up the courage to deliver bad news.

Pedro’s daughter almost seemed to sense my trepidation. She couldn’t have been more than 8 years old, but that didn’t keep her from staring at me with doctor-suspicious eyes, as if I might be the boss of her father’s fate. Whenever she did this, I smiled at her and turned my attention toward Pedro. “Is there anything else I can help you with?”

A couple of days later, I traveled to Chicago to participate in a panel discussion that gathered palliative-care specialists from around the country with patient advocates, ethicists, social workers, and internists (like me), as well as representatives from organizations such as the American Association of Critical-Care Nurses and the Society of Hospital Medicine. The central question: How can we improve end-of-life care in the hospital? While everyone brought a different perspective, what bound us together, caregivers and the bereaved alike, was how much the experience of a hospital death had impacted us—how impersonal it had become, how mechanized, how inhumane. One of the panelists described losing her 36-year-old husband to metastatic colon cancer. Even though she saw a multitude of doctors every day, when her young husband found himself struggling to breathe near the end, none of them dared to discuss the inevitable. “No one told us anything,” she said.

That’s when I thought back to Pedro. By not telling him clearly what the progression of his cancer meant, had I inched him toward a hospitalized death, one that involved shocking his heart if it stopped and pureed food and waking him up every four hours for vital signs? The reason I had been invited to the panel in the first place was an essay I wrote about the difficulty of giving end-of-life care to undocumented patients. I described one patient in particular, a Guatemalan man who did not want to spend his last weeks cycling through the emergency room for pain medications. With the help of the consulate, my colleagues and I arranged to fulfill his dying wish to return to his home country. But the interest and care I’d shown this one patient meant nothing for the next. In not fully explaining Pedro’s prognosis to him, I simply hadn’t done my job.

Or was it my job? Last month, Medicare announced that it would begin to reimburse health-care providers for discussions on end-of-life options, sparking a new debate about who, exactly, should be having those discussions. Whose responsibility is it to clarify how many times a patient wants to be shocked if her heart stops? The critical-care doctor? Who should give the patient a well-informed and plain-spoken prognosis? The oncologist? One of the words that kept coming up in the meeting in Chicago was ownership. In the American medical system, with all its experts, shift work, and moving parts, it can be difficult to place ultimate responsibility for a patient’s care on one individual. That is to say, responsibility is shared—which is how certain duties, like talking with a patient about how close he is to death, can fall through the cracks.

But I can’t help but think that it was I and I alone who failed Pedro. I wasn’t his oncologist, I wasn’t the interventional radiologist, but of all his doctors, I was the one who could best communicate with him. I spoke his language. As it stands right now, there’s no way to guarantee that patients like Pedro receive counseling about different care options (maybe he doesn’t want to go through another round of chemotherapy) or help explaining their end-of-life decisions to family members (maybe he doesn’t want to spend his final days in an ICU).

Under the new Medicare proposal, scheduled to go into effect this fall, any qualified team member—a doctor, a nurse, an assistant—can bill for the time it takes to discuss all the different procedures and interventions that a patient like Pedro might face. Had this been an option during Pedro’s hospitalization, somebody else caring for him might have caught my oversight and talked with me about it, or perhaps held a conversation with Pedro herself and billed for it. Medicare’s reimbursement scheme doesn’t just incentivize holding difficult discussions, it also assigns responsibility. It’s a way of establishing ownership over a difficult conversation.

The day after the Chicago meeting ended—the same day Medicare announced its new plan—I tried finding Pedro in the hospital. I wasn’t scheduled to work, but I thought I might make up for my lack of clear communication by telling him what the new findings really meant. Unfortunately, Pedro was gone. I saw in the chart that the spinal procedure had gone smoothly and that he had actually walked out of the hospital.

A month later, I saw his name outside one of the doors in the cancer unit. Since our last visit, he’d lost weight and endured awfulness, his femur snapping spontaneously as he attempted to walk one morning, so overrun was it by tumor, but somehow Pedro retained his smile and grace. I told him I’d thought so much about our conversations that I wrote an article about him, one I hoped would help doctors think about how they communicate bad news, and he gave me permission to use his name. Fortunately, another of the hospitalists had taken the time to hold the difficult conversation with him. Pedro and his family knew he would soon die, and were preparing for such.

Still, I couldn’t help but feel a professional shame, one I used to feel as a younger doctor when nurses called to remind me of some routine task I had forgotten about, one that made me occasionally punch myself in the thigh and say, “I really need to remember to do that next time.” For Pedro’s sake, I really do.

Maplewood death shows critical need for end-of-life directive

Share

Paramedics and nursing home workers across Minnesota can relate to the difficult decision that was made.

Gloria Scott, right, signs a “do not resuscitate” order while at the hospice wing of Margaret Tietz Nursing and Rehabilitation Center in the Queens borough of New York on Nov. 26, 2009. At left is her physician, Dr. Lauren Shaiova.

A life-or-death decision by Maplewood paramedics, who stopped life support for an elderly woman at her husband’s insistence, underscores why individuals should have legal documents spelling out the care they want in what can be frantic and confusing end-of-life emergencies, health officials said Wednesday.

Paramedics and nursing home workers across Minnesota can relate to the difficult decision that was made Aug. 7, when medics initially revived 71-year-old Linda Sandhei and started wheeling her to an ambulance, only to have the woman’s husband tell them to stop, according to a police report of the incident. Sandhei died soon after.

Advance directives and do-not-resuscitate (DNR) orders can provide clear guidance for such high-stress decisions. But absent those documents, medics are often asked to trust relatives who are distraught and may not know the wishes of their dying loved ones, said Dr. Jeffrey Ho, medical director for Hennepin County Medical Center’s emergency management services (EMS).

“What we’re trying to avoid is some random person coming up to us and saying, ‘Stop, I don’t want Mabel resuscitated!’ And we ask, ‘Well, who are you?’ and he says, ‘Oh, I’m her son,’ ” Ho said. “We have no way of verifying if that’s true or not, and we really have no way of verifying whether Mabel would actually want to be resuscitated or not.”

Research has shown that patients’ wishes are followed more often when spelled out in advance directives, and that relatives suffer less stress and anxiety. But such documents remain uncommon, even after a coordinated campaign called Honoring Choices by Minnesota’s eight major health care systems to get more people to complete them. The state’s top system had completed directives from just 32 percent of its elderly outpatients, according to a study last year.

Sandhei, who had suffered from Parkinson’s disease for two decades, either hadn’t completed a directive or didn’t have one filed with the Good Samaritan nursing home in Maplewood. She was transferred there in July after being admitted to Regions Hospital, according to a police report.

Her son was at her bedside around 4 p.m. Aug. 7 when she vomited in her sleep and stopped breathing. Sandhei’s husband, Tom, arrived later and stopped the medics from loading his wife in an ambulance for transfer to a hospital. He declined to discuss the incident when reached by phone Wednesday.

Written directives aren’t always the final word in a high-stress situation when someone is dying and relatives are angry or scared. Paramedic Mike Trullinger has tried to follow DNR orders for dying patients only to be threatened by distraught relatives with lawsuits, a baseball bat and, in one rural case, a shotgun pointed at him.

“The patient had a DNR order, but the family member had a shotgun. So we performed CPR anyway,” said Trullinger, now a supervisor for HCMC’s EMS. A sheriff’s deputy eventually arrived and the man put down the weapon and became apologetic, Trullinger said. CPR failed.

Ho said his medics, too, have experienced tough situations even when patients had written documents. Sometimes the document might be improperly dated or lack a doctor’s signature, calling it into question. Other times relatives are scrambling to dig up the document from files while medics are proceeding with CPR.

Frequently, relatives who thought they were prepared to see a loved one die have a change of heart when the moment arrives.

Regardless, Ho said having that paperwork completed resolves more confusion than it creates and leaves people feeling confident in their end-of-life decisions.

“It’s a very difficult decision to be making in a split second with limited information,” he said. “It’s tough to be second-guessed afterward.”

Err on the side of life

The Maplewood Fire Department policy manual instructs medics to follow written orders but otherwise pursue resuscitation: “Until properly completed orders are presented, pre-hospital personnel will assume that no valid DNR orders exist and proceed with standing orders for resuscitation as medically indicated.”

A Hennepin County protocol governing HCMC, North Memorial, Allina, Ridgeview and Edina EMS agencies provides similar advice.

“If we are going to start a resuscitation, we need to do it right then and there,” Ho said. “If the information is not clear to us, then we are erring on the side of starting resuscitation, because we can always stop it later.”

Nursing home workers operate under similar assumptions, said Patti Cullen of Care Providers of Minnesota, a trade group for nursing homes. “From a legal perspective, we advise our members that without the presence of this DNR that is signed, that’s official, they’ve got to do every lifesaving measure, because families will sue if you don’t save a life. They won’t sue if you break ribs because you did CPR.”

The fact that the Maplewood medics halted life support in the absence of a written directive for Sandhei suggested to Ho and Cullen that they had enough information from the relatives or nursing home staff to override the bias toward continuing lifesaving efforts.

Maplewood police made no arrests in the case after an investigation concluded that the medics acted in “good faith.” The term is defined in the state’s advance-directive statute as acting in the best interests of a patient in any way short of assisted suicide.

Six Maplewood firefighters, including the chief, were suspended after a complaint was filed, but city officials declined to confirm whether the complaint was linked to Sandhei.

Cullen sympathized with the relatives and first responders, who she said appeared to act in the best interests of the family and patient.

“You know, the reason for doing that legal document,” she said, “is to get all of the family members on the same page.”

In this intimate portrait, Philip Gould wrestles with the meaning, and unexpected ecstasy, of impending death

 

 

 

Philip Gould was diagnosed with cancer of the oesophagus in 2008, and in the summer of 2011 he was given three months to live. Filmed during the last two weeks of his life, this intimate portrait reveals Gould’s quest to find meaning in what he called ‘the death zone’.

Gould believed that for the terminally ill and those close to them, there can be moments of joy, resolution and inspiration just as intense as those of fear, discomfort and sadness.

‘I am not redefining death, I am offering another way to perceive dying. I have been offered an opportunity to live every moment until there are no more moments for me to live and for that I will be eternally grateful.’
