What is â€œHopeâ€ for a Patient with a Brain Tumour?
By Henry S. Friedman, and Maia Szalavitz
The Brain Tumor Center at Duke University runs more clinical trials of new treatments for brain tumors than virtually any other center in the world. For patients not in these trials, the Center tries drugs approved for other cancers and promising against brain Cancer cells in the laboratory. The Centerâ€™s surgeons operate on brain tumors that others have pronounced Inoperable. It is a battle that buys about 10 to15 percent of their patients another three to ï¬ve years of life. The Centerâ€™s motto is â€œAt Duke,there is hope,â€ but is the hope real? Is it worth the struggle? And what is â€œhopeâ€ when no treatment is working? For the sake of his patients,the oncologist who co-directs one of Americaâ€™s largest clinical programs for patients with brain tumors is aggressive, experimental, indignant,and compassionateâ€”but always hopeful.
Brain cancer is one of our most terrifying diseases. All too often, it kills with appalling speed; the most common primary brain cancer in adults, Glioblastoma Multiforme, is also the deadliest. In the United States, only half of patients receiving the standard treatments survive for a year after diagnosis. Fewer than one in ten are alive ï¬ve years later. In adults, there are about 17,000 cases of primary brain cancer each year (in addition, cancer can spread to the brain from some other part of the body), resulting in about 14,000 deaths. Brain cancer is the third leading cause of cancer deaths among adults aged 20 to 39, and the biggest killer among cancers of children and young people up to age 20.
The fear that brain cancer brings runs Deep. This cancer assaults the organ of the selfâ€”the seat of our mind, emotions, and basic sense of control over our bodiesâ€”and so threatens to alter and destroy who we are. Symptoms vary depending on what part of the brain is affected. The frontal lobes, the part of the brain right over the eyes, are involved with decision making, mood, and judgment. Tumors that inï¬ltrate both frontal lobes can induce personality changes (for example, in levels of inhibition), lack of initiative, irritability, depression, and Paralysis.
Tumors located in, or pressing on, the language areas of the brain are usually in the Posterior part of the Frontal Lobe, in the Temporal Lobe behind the eye and above the ear, and usually on the side opposite to the personâ€™s handedness. They may bring problems with speaking, understanding speech, thinking, and writing. Tumors hitting the visual areas, which are at the back of the brain, may cause distortion of sight, including blindness. Brain-stem tumors are deep in the brain within its stalk, which extends from the top of the spinal cord. These tumors can cause vomiting, swallowing and speech problems, lack of coordination, clumsiness, and muscle weakness in the face that may cause a personâ€™s smile to appear crooked and cause loss of coordination of eye movements. All brain tumors can lead to seizures, which may be manifested as subtle alterations of mood or levels of consciousness. Interestingly, brain tumors are only rarely a cause of headaches.
Obviously, the entire brain cannot be cut out, but Malignant brain tumors are not neatly circumscribed; they have edges that inï¬ltrate normal brain tissue. Nor does the brain tolerate well the slashing, burning, and poisoning that still characterize much of the arsenal of modern cancer medicine. The bodyâ€™s need to protect the brain at all costs means that even reaching a brain tumor with medication, radiation, or surgery is much harder than reaching cancers in other areas. No other organ is tightly enclosed in its own protective bone case; and no other type of cancer treatment must breach a defense like the blood-brain barrierâ€”the tightly knit system of blood vessels and cells that keeps out or immediately expels most foreign substances, including medicines, from the brain.
The comparatively few cases of primary brain cancer each year (in comparison to, for example, lung or breast cancer) make it what is called an orphan condition. Studying it offers little potential proï¬t to pharmaceutical companies and little promise of wide impact to the supporters of biomedical research, so these groups invest very little time and money in it. Indeed, most brain tumors are secondary, originating in other organs (frequently the lungs or breasts) or in skin melanomas and spreading to the brain only late in the course of illness. About 170,000 of these brain Metastases are diagnosed each year. The bitter consequence is that by the time cancer is discovered in the brain, it usually has spread widely from its original site in the body. If treatment is already under way for the primary cancer, its appearance in the brain means that the therapy is failing and the cancer is out of control.
As a result, when physicians see brain tumors, they tend to give up. Either they have found a voracious primary tumor, for which they can merely relieve the symptoms, or they have discovered a sign that treatment is failing. They often tell patients that â€œthereâ€™s nothing more we can do.â€ Indeed, the majority of patients I see as co-director of the clinical neuro-oncology program, the clinical arm of the Brain Tumor Center at Duke University, have been told that there is no hope. Scott Beckert, the husband of one such patient, said simply: â€œThe doctors at home said she had six months to live, that the cancer was inoperable, incurable, hopeless.â€ Like Eileen Beckert, most of my patients arrive here having been sent away from somewhere else to die.
The overriding goal of the Brain Tumor Center at Duke is to give these patients hope and keep that hope alive as long as any chance remains for ï¬nding a treatment that prolongs life. It is a philosophy that raises difï¬cult ethical questions: What constitutes legitimate hope? How aggressive should treatment be when the unambiguous alternative is death? When treatment options run out, what can and should we do?
In the early 1990s, Duke modiï¬ed its approach to brain cancer. The distinctive combination of specialties and interests represented in the centerâ€™s current interdisciplinary leadership emerged at that time. I had been trained as a pediatric oncologist, but became interested in helping adults as well; Allan Friedman, M.D., co-director of the clinical neuro-oncology program (no relation, though we are often asked), was an adult neurosurgeon who wanted to learn more about pediatrics and neurooncology. I had trained in the laboratory of Darell Bigner, Ph.D., who directs the Brain Tumor Center and its research, so I knew of the challenges in coordinating the laboratory and clinic. We merged the adult and pediatric clinical programs for brain tumor patients and sought the tightest possible link between research and practice.
MORE CLINICAL TRIALS FOR MORE PATIENTS
Clinical trials make medicine a science. Before they were introduced in the mid-twentieth century, medical treatment was based on instinct, guesswork, and what a particular doctor had been taught at a particular school. Because even without treatment many conditions improve over time, and because the belief that a medication will work occasionally produces improvement or even a cure, totally ineffective treatments were often deemed successful and used for generations.
To discover real weapons in the battle against disease, scientists evolved techniques that, in combination, constitute todayâ€™s Phase III clinical trial. In a Phase III trial, to separate out any possible effect of a patientâ€™s simply believing in a treatment, some patients are given the new treatment and others a comparison treatment. The comparison treatment may be a placebo or, in the case of brain tumors, the standard therapy, which means that any difference between the two treatment groups should show true effectiveness of the new therapy.
Patients do not know which treatment they are getting, so the study is characterized as â€œblind.â€ Furthermore, assignment of a patient to one or the other treatment is random, so that the researchers cannot unconsciously select the most promising candidates for the new treatment and assign the sicker ones to the comparison group, thus biasing the results. Finally, to keep the researcherâ€™s potentially misleading hope or optimism at bay when he is assessing how well the patients have done under each treatment, researchers do not know which medication has been given to which patients. This makes the trial â€œdouble blind.â€
Every clinical trial to get a new drug or therapy approved has three phases. Phase I tests ask whether the drug is safe for human use and what is the optimal dose. Here, both patient and scientist know that the real drug (not a control treatment or placebo) is being given, and escalating doses are used to ascertain how much can be used to attack the cancer without producing unacceptable side effects. Patients in Phase I trials are medical heroes, frequently the ï¬rst humans to try a drug previously tested only on animalsâ€”a drug that may have unknown and even deadly effects. Their chances of seeing improvement are impossible to quantify, although, of course, treatments are not tested unless there is good evidence from animal experiments to believe they are promising. If the drug is effective, these patients are ï¬rst to beneï¬t.
Treatments established as safe in Phase I move to Phase II, which asks what effect the drug or other therapy has on the disease or disorder. In Phase II, a single group of patients gets the new treatment and is closely followed to see whether it is working. Phase III is frequently a randomized trial of the kind described earlier involving many patients and comparing the new treatment to the present â€œstandard of careâ€â€”the best treatment already in use.
OPERATING ON THE â€œINOPERABLEâ€
Eileen Beckertâ€™s tumor was located directly on the speech area of her brain. She had been told that it was inoperable. Because of the poor Prognosis for brain cancer in general, and the propensity of tumors to grow back after surgery, many surgeons do not even try operations in cases like this. One result is that they do not develop the skill that comes with having done hundreds of them.
We believe in giving patients their best chance. As Allan Friedman puts it, time is precious. No one lives forever, but he sees his job as getting his patients as much quality time as possible. Many patients he sees have already been turned away by other surgeons.
Allan was an unlikely candidate for excelling at neurosurgery. The ï¬rst time he observed an operation, he fainted when the surgeon made the ï¬rst cut. He now says that, while you may never get used to it, the surgery eventually becomes fairly routine. Now, he does 12 operations in a typical week, each lasting about 4 hours.
To perform a difï¬cult operation like Eileenâ€™s, a surgeon must visualize the procedure in his head before he begins. He takes every precaution to avoid mistakes and so goes in with conï¬dence. â€œYou donâ€™t think in terms of what you are going to do. You think in terms of what pitfalls you are likely to encounter and how to avoid or deal with them,â€ says Allan.
For example, bleeding is a major problem in brain surgery. With other organs, loss of blood or exposure to excess blood is not necessarily a problem, but loss of blood ï¬‚ow to an area of the brain can quickly produce damage. Any chance that a surgical move will cause unexpected bleeding must be anticipated and, if possible, prevented. Here good preparation can make the difference between life and death, disability and normal functioning.
To achieve the most intense concentration during surgery, Allan has to distance himself from the person on the operating table. He says that there are still times during an operation when he catches himself thinking about the person and has to stop for a second to dissociate himself from the human attachment, which distracts him from the mechanical process. The patient, on the other hand, should be distracted if awake during the surgery. There is always a technician talking to the patient. Allan says: â€œI donâ€™t want the patient sitting there thinking, â€˜Oh, my God, my headâ€™s open! Whatâ€™s going on?â€™ They shouldnâ€™t be left to their own thoughts.â€
To avoid damaging the language centers of the brain, neurosurgeons electrically probe areas that they consider cutting to see if disrupting the signaling at that location interferes with speech. If a man speaks several languages, he must be tested in each one because each may be localized in a different brain region. Probing one area may show no effects on the ability to speak English, for example, but cutting it might bar the person from speaking Spanish. One patient of ours was a rabbi who spoke English, Hebrew, and Yiddish, each localized to a different area of his brain. You do not want a rabbi waking up no longer able to speak Hebrew!
Because we deal with the brain, the fear factor among patients is high. Many feel sure they will not be able to tolerate being conscious during the operation. Yet, during hundreds of surgeries he has done on conscious patients, Allan has never had someone become unbearably distraught or agitated. For the most traumatic parts, such as opening the skull, the patient is under general anesthesia; but any time a patient is conscious there is someone in the operating room whose sole task is to talk to the patient.
Eileen Beckert, who was a 47-year-old mother of four children when she was Allanâ€™s patient, said: â€œThe day before, I was really nervous. I thought: What if I donâ€™t wake up? I wrote a letter to my kids, just in case.â€ Though she was conscious for parts of her operation, Eileen cannot remember much of the operation itself: â€œI do remember lying in pre-op and just praying. And I remember at the end, I couldnâ€™t talk for a while.â€
In fact, for several weeks after the operation, as she recovered in the intensive care unit, Eileen could not initiate speech. Her husband, Scott, says: â€œI would say â€˜Simonâ€™ and she could say â€˜Garfunkel,â€™ but she couldnâ€™t start.â€ This is probably because the areas for planning speech were temporarily disconnected from the areas that execute speechâ€”the result either of the surgery itself or of postoperative swelling that interfered with the connections. When she was cued by external speech, Eileenâ€™s speech-planning areas did not have to come into play.
Eileen also endured three terrifying days when she entirely lost the ability to speak, probably as a the result of brain swelling during recovery. Her speech is entirely normal now, nearly two years after the surgery, but she has some problems with concentration and focus that prevent her from returning to her job (ironically, as an oncology nurse). Treatment for cancer, and sometimes the tumor itself, in any region of the brain, can cause this problem. Eileen has completed her radiation and Chemotherapy treatments and at her latest checkup showed no sign of tumor regrowth.
LIVING AND DYING WITH HOPE
Research will soon bring us better treatments. We are immensely optimistic. But the question we are asked most often is: Are you offering false hope to patients now, today, by treating their tumors so aggressively?
I have tried to characterize in scientific and ethical terms why we favor aggressive treatment, but how does it make patients and families feel about their chances? We have one good yardstick. The families of patients who have died should be our harshest critics, but rarely has a family said we gave them false hope. They are glad that their loved one preserved a sense of optimism about the future and got the best shot at prolonging it.
We want every remaining moment to count for a patient, and every patient has a right to the best that science and spirit can bring to the ï¬ght.
When we say that â€œAt Duke, there is hopeâ€â€”the motto of our centerâ€”we mean more than the potential for physical survival, although we ï¬ght ï¬ercely for that. We also mean there is hope that the patientâ€™s remaining time, long or short, will be worth living. We believe that a patientâ€™s psyche can affect this disease. When a doctor at home tells a patient that nothing can be done, the patient and his family believe that he is half-dead already.
If a tumor is not responding to treatment and we must conclude that further attempts will fail to improve the patientâ€™s Quality of life, we say so. But our team is devoted to quality-of-life concerns and does everything possible to ensure psychological and spiritual support, as desired, for both patient and family. Our family support center is the model for dozens of similar centers in hospitals across the country. We conduct research on our quality-of-life services to see which ones help patients most, and so we can use our resources most effectively. What I am saying is that â€œhopeâ€ changes as situations and expectations change. Like a quilt that keeps you warm and comfortable when it is dark and cold, hope may be patchwork, but there are distinct patterns.
As for us, the Centerâ€™s staff, we often battle death, giving no quarter, and then must turn and accept it. Cancer medicine is a ï¬eld with tremendous burnout. You can absorb only so much sadness and keep responding. I can tap into the feelings of loss, butâ€”like many doctors who treat often-fatal illnessesâ€”I also have a protective mechanism that enables me to go on providing care and not lapse into sadness that would get in the way of the medicine. Because I love sports, I believe in the mind-set of a team ï¬xed on victory. If you play or watch basketball, you know that a team can change the gameâ€™s outcome right up till the very end. We want every remaining moment to count for a patient, and every patient has a right to the best that science and spirit can bring to the ï¬ght.

In January 2009, Andrew McGill and Natalya Jagger, asked photographers on DPChallenge.com to help them complete a unique project in memory of Andrew's daughter, Rose.
Photographers were asked to shoot their idea of hope during March 2009, Brain Tumour awareness month (UK), and this inspirational book, 'With Hope in Our Hearts' is the result.
In his introduction for the book, Henry Friedman, Deputy Director of The Preston Robert Tisch Brain Tumor Center wrote â€œThis wonderful book produces images that will help anyone and their family battling a brain tumor and indeed any other medical or even non-medical challenge. I believe all readers will find this to be deeply moving book and an essential ingredient for their own personal quest for health and happiness.â€
All Profits from the sale of this book will go to BT Buddies, an organisation dedicated to providing information, inspiration and hope to anyone affected by a brain tumour.
