I haven’t written about cancer for about three months. That’s a long time for me. I’m a journalist, and I’ve been writing regularly about the disease since I was diagnosed with breast cancer in 2010.

But suddenly, in late June of this year, I just felt tired of the whole cancer rigmarole. Eight years out from diagnosis, and I felt tired to my bones. Exhausted. Ready to quit.

Don’t get me wrong: I’ve been NED for years. As far as I know, I’m healthy. But I still participate in cancer groups, read cancer support group mailing lists, subscribe to a “cancer patient” Google alert. I still feel a sharp intake of breath when I learn that an acquaintance has a new diagnosis, or a recurrence.

Do you ever feel sick to death of cancer? Do you just want to go back to that time before a doctor said, “I’m afraid the biopsy shows you have cancer.”? Do you find yourself sick to death of the worry, the uncertainty? Are you tired of people looking at you funny because you have a scarf on your head? Or are you just bored with trying to figure out how to tell people you’ve had cancer without it turning into a huge conversation where you have to reassure the person who doesn’t have cancer? Are you done with side effects? Weight gain? Neuropathy? Sexual dysfunction? Are you over work insecurity, wondering whether to tell your boss or your co-workers?

I just went on strike. For three months, I didn’t think about cancer.

But then, a couple weeks ago, my teenage daughter woke me up in the wee hours of the morning.

She was shaking, as if she was the 9-year-old she was when I was diagnosed, and not the almost grown, 17-year-old she is today.

 “I dreamed that you got cancer again, and that you were going to die.”

GD Cancer. You just had to come roaring back into my life again, didn’t ya? I had to make my annual cancer checkup appointment this week. I found out that another acquaintance had died. Reluctantly, I gave up on giving up.

Having cancer; having had cancer; having a loved one with cancer—it’s all exhausting.

But sticking your head in the sand forever is dangerous. I have an acquaintance who took a cancer vacation that lasted for years. She stopped getting mammograms. You know where this is going: She eventually had a recurrence, and it was much worse because she’d waited until she could feel the tumor, rather than having it detected earlier by regular screening.

I hate it when people say, “It’s all good.” Things are NOT all good. Cancer is not good, for sure. But if I’m honest, cancer also constantly reminds us that time is not infinite. It goads us to make the most of what we have. It challenges us to savor the moment, make that phone call, hug that friend, pursue that dream.

Our society conspires to make everyone deny the reality of death. Those of us who’ve been touched by cancer don’t have that luxury. That’s a gift, really. It gives us clear vision, urgency. Oh yeah, and teenagers with nightmares. Also, gratitude for each day. Like most things in life, it’s a mixed bag, this cancer.

No, we’ll never know if we’ve survived cancer until we die of something else. The trick is to make the time between now and then count.

Take a cancer vacation for a while if you must. It’ll always be there waiting for you when you’re ready to pick it back up. Having had a rest, you’ll be ready to fight another day.

Tired of the Cancer Conversation

EARLY ON IN HIS career, Andrew Chi, M.D., Ph.D., chief of neurooncology and co-director of the Brain Tumor Center at NYU Langone Health in New York City, learned to be careful in how to introduce his new patients with glioblastoma multiforme (GBM) to palliative care; that is, care that does not seek to cure but to improve pain management and quality of life.

“(The) current consensus is to, ‘Start talking about palliative care early. Be realistic.’ But if you don’t approach those topics carefully with new patients, they may not come back,” Chi explains. “If you’re a young man in your 40s with kids, and you’ve just been diagnosed, most likely you want to talk about fighting, not looking to ease suffering.”

After several patients failed to return for a second visit, Chi changed the way he talked about this issue. “During my initial visits, I often call it ‘supportive oncology,’ instead of palliative care,” he says. “I advise our patients with GBM to see our palliative care practitioners early to talk about social support, depression, pain management, help at home.”

Chi emphasizes that the provider’s role is palliative care. He deemphasizes the association with hospice care, instead focusing on palliation, or alleviation of suffering. Unfortunately, the term palliative care, which nearly all doctors say, has been linked in the public’s mind to hospice and end of life. This leads many patients to fear the concept.

A December 2017 study in Current Oncology found that when patients learned that palliative measures can complement curative treatments, most of them expressed interest in these services.

GBM poses many challenges for patients: Abilities often decline quickly after diagnosis, and treatments can be aggressive.

Neither patients nor their loved ones and caregivers feel they have time to consider social support, mental health and so on when they are dealing with an avalanche of medical information and fighting for life. But doing so can reduce stress and increase quality of life, experts say. Even patients who do well from a standpoint of cancer may continue to live with physical and emotional distress.

“We consider palliative care one of the essential pillars of caring for patients with glioblastoma,” says Vinai Gondi, M.D., director of research and education at Northwestern Medicine Chicago Proton Center in Warrenville, Illinois. “There are a wide range of initiatives seeking to give these patients access to supportive care, how best to help support needs at home.”

Many patients with GBM are too ill to attend support groups and meet with counselors outside the home, explains Richard Dickens, MS, LSW-R, director of client advocacy for CancerCare, a nonprofit organization that provides counseling, education and other support to patients with cancer.

Dickens suggests that patients with GBM join a telephone or online support group to connect with others in a similar situation. CancerCare offers these groups for both patients and caregivers. Online services to coordinate a group of caregivers also are available from other groups, such as Lotsa Helping Hands.

“Patients with GBM have big issues,” explains Sean Grimm, M.D., director of neuro-oncology at Northwestern Medicine Cancer Center, also in Warrenville. “They go from working to not working, they suffer from depression, they need help at home. They need help getting disability. They have neurologic symptoms that require rehab and physical therapy. They need help with nutrition. All (of) these things are important. Palliative care includes all (of) these things.”

The approach used in discussing palliative care can play a role in whether a patient seeks help.

Power in the Words: Discussing Palliative Cancer Care

Six years ago, Anne Murray, an occupational therapist, visited John Andrew Boockvar, M.D., vice chair of the department of neurosurgery, and director of the Brain Tumor Center at Lenox Hill Hospital, a member of Northwell Health, the largest health care system in New York state. Murray had received a diagnosis of glioblastoma, often referred to as GBM — one of the most aggressive forms of brain cancer.

With her prognosis dire and worried about her then 9-year-old son, she consulted with Boockvar, who was an attending physician at Weill Cornell Medical Center at the time, about a clinical trial of an experimental treatment using intra-arterial drug delivery in which the tumor blood vessel-inhibiting drug Avastin (bevacizumab) would be administered directly to her tumor, as opposed to systemic therapy (intravenously). She responded so well to this one-time treatment that she felt as if a fog had cleared when she woke up. “I went in to the procedure pretty confused,” says Murray, now 48. “But when I woke up, I knew where I was. I knew that my husband was waiting for me in the ICU step down unit. I knew what I had just been through. I asked the nurse, ‘This is crazy, but could this have already worked?’”

In the months that followed, Murray’s tumor, which had been growing out of control, shrunk back to a manageable size. Murray now goes for regular MRIs, but doesn’t take any medication. She also works a few hours a week. She feels her positive attitude has come from the support she receives from her caregivers, friends, the community and her church, St. Rose of Lima.

“The fact that I got to celebrate my son’s 15th birthday was such a gift,” says Murray, who lives with her son and husband in Newtown, Connecticut. “I didn’t know if I was going to be around. We do a lot of celebrating around here.

I’ve set a new goal: I want to dance at my son’s wedding.” This sense of hope wasn’t always the case in this disease type. “If you read glioblastoma textbooks, this type of response shouldn’t happen,” says Boockvar. “We used to be nihilistic, just do a needle biopsy and that’s it. We thought there was nothing we could do to prolong the lives of patients with GBM. Now, there’s optimism in the field. My slogan now is ‘strive for five.’ We can keep 5 percent of patients with glioblastoma alive for five years. Then we can hope that during those five years, another treatment will come along and that will allow us to keep patients alive for another five years.”

GBM remains incurable, a devastating malignancy. However, Boockvar points out that 30 percent of patients will survive two years. Of those that make it to two years, half will make it to three years. And then there are the five-year survivors. A 2009 study found that as many as 10 percent might make it this far. Some live even longer: Boockvar has a patient diagnosed at 20 years old who is now nine years out, getting on with his life and going to college.

Brain cancer specialists emphasize that these long-term survivors are outliers. A generation ago, only the very rare patient with glioblastoma survived this long and the median survival after diagnosis was nine months. Now, that median survival figure, taking into account the whole range of outcomes, has crept up to 14.6 months. Meanwhile, advances in surgical and radiation techniques, new drugs, better diagnostics, and a newly energized research community seem to indicate that the outlook will continue to improve. “We’re not just looking for random outliers,” explains Andrew Chi, M.D., Ph.D., chief of neuro-oncology and the co-director of the Brain Tumor Center at NYU Langone Health in New York City. “We’re looking to learn from those outliers. Maybe we can unlock the keys as to why those patients survive so long.”

Gliomas are a malignancy of the brain’s supportive tissue, or glial cells, from the Greek word for glue. Astrocytomas, a type of glioma, arise from one kind of glial cell, called astrocytes because the cells are star-shaped. GBM is the highest grade of glioma (grade 4) and is the most malignant form of astrocytoma. About two-thirds of gliomas are GBM. In the United States, approximately 12,000 new cases of GBM are diagnosed each year.

As brain tumors grow, they often crowd out or interfere with normal brain structures and functions, creating symptoms such as headaches, seizures, memory loss and behavior changes. Experts say that several things make GBM particularly challenging: First, it occurs in the brain — that limits how much of a tumor can be taken out or irradiated. In addition, this malignancy grows behind the blood-brain barrier, which is a wall of specialized cells that keeps most compounds from migrating from the bloodstream into the brain. That makes it difficult to deliver drugs to GBM tumors.

As if that weren’t enough, GBM tumors are diffuse, tentacle like spreading through the brain rather than concentrating in one or several places like most breast or lung tumors. And spidery GBM is always aggressive, changing and morphing to escape from immune cells and other enemies. One part of a tumor may have different genetics in different areas. Often, when these tumors recur, the genetics have completely changed, making them an entirely new adversary to the medical team.

“One of the biggest challenges of this disease is that it is so heterogenous. That is, it’s so different in every patient, and not every part of the tumor is the same. You’re playing whack-a-mole, trying to kill all (of) the different kinds of GBM cells,” explains Linda Liau, M.D., Ph.D., M.B.A., director of the Brain Tumor Program at the University of California Los Angeles.

One of the most profound advances has been the Food and Drug Administration’s (FDA) approval of two medications specifically for the treatment of GBM: In 2005, Temodar (temozolomide) received full FDA approval for the treatment of adult patients with newly diagnosed GBM concomitantly with radiotherapy and then as maintenance treatment. The medication works by damaging the DNA of tumor cells, leading to cell death. Then, in 2009, the FDA granted accelerated approval to Avastin for GBM that occurs after prior therapy. Last year, it received full approval. Avastin can control swelling caused by the cancer, or by treatment, thus decreasing dependence on corticosteroids that can have serious side effects. However, it has not been proved to improve survival outcomes.

Researchers continue to look for new drugs, or new combinations of old drugs, that may be effective, such as BiCNU (carmustine), Gleostine (lomustine), Gliadel wafer (biodegradable discs infused with BiCNU), Temodar, cisplatin, carboplatin, etoposide and irinotecan are examples of cytotoxic drugs that kill tumor cells. They may be given as a single agent or in combination. For instance, two commonly used combinations in GBM include procarbazine, Gleostine and vincristine, as well as carboplatin/etoposide, according to the American Brain Tumor Association. Not all of these drugs have been approved by the FDA. Only BiCNU/Gleostine, Avastin, Gliadel wafer and Temodar are approved for the treatment of high-grade gliomas. Others are approved for the treatment of different cancers, and must be prescribed off label for brain tumor use. “There are probably nine off-label drugs for glioblastoma that probably work,” explains Boockvar. “But we’re waiting on the data.”

Meanwhile, a new era in which genetic sequencing — analyzing the genetic code of tumors &mdash; has become faster and less expensive and has led to the identification of many potential genetic and metabolic targets that might lead to breakthrough treatment. It has also made more fine-grained diagnosis possible that combines genetic information and how tumor cells look under a microscope. Doctors use both genetic sequencing and imaging techniques, such as MRI with contrast dyes to make the tumor cells stand out and CT scans to diagnose the disease and characterize it.

For instance, based on genetics, GBM has been divided into two major subgroups: IDH wild-type (90 percent) and IDH-mutant (10 percent). IDH wild-type GBM tends to be more malignant, so knowing the subtype helps physicians decide how aggressively to design treatment. In addition, GBM tumors with an inactive gene called methylated MGMT, found in 50 percent of GBM cases, predicts longer survival.

Genetic mutations, changes in what proteins are produced under the direction of those genes, point to other potential GBM markers. For instance, many growth factor receptors — epidermal growth factor receptor, vascular endothelial growth factor, platelet-derived growth factor receptor &mdash; are either mutated or overexpressed in GBM, thus removing the cellular brakes and allowing the tumor cells to go into overdrive. Ongoing clinical trials are now testing treatments that could inhibit these growth factors. One clinical trial is testing a DNA vaccine, INO-5401, that seeks out three markers overexpressed in GBM. Other trials are examining AG-120, an oral drug that inhibits the IDH1 mutation.

“We’ve learned a lot of biology in the last 10 years,” says Chi. “We need to study each one of these subgroups, both in terms of biology and in terms of what works in the clinic. We will be able to treat one subgroup eventually, and it will take off from there.”

“There is just a ton of research going on right now. There’s real ferment,” says Sean Grimm, M.D., codirector of the Brain Tumor Center at Northwestern Medicine Cancer Center in Warrenville, Illinois.

Most experts caution that it will take time to figure out ways to design and deliver drugs that can reach those various targets, and to figure out what works. Various research groups are working on myriad ways to get around the blood-brain barrier.

They are using gold nanoparticles, viruses (polio, adenoviruses or herpes virus), specially engineered genes, antibodies and stem cells, combining viruses with oral drugs. In a sense, these delivery mechanisms, or vectors, act like specialized smart bombs that can get around the brain’s defenses and deliver treatments where they need to go.

Other methods in clinical trial are more mechanical: Some teams spray chemotherapy agents into the surgical site. Others leave radioactive beads or biodegradable wafers to deliver a high dose of local radiation. Convectionenhanced delivery employs a pump to slowly drip anti-tumor agents into the site. In another method, a biodegradable Gliadel wafer that cannot be removed is left in the tumor cavity after surgery to release a chemotherapy drug into the tumor tissue.

In tandem with drug development, GBM surgery has been making strides. GBM cells spread like tentacles, as previously mentioned, and usually cannot be totally removed, surgeons say. Additionally, brain tumors are not always visible, nor are they always easy to access. A century ago, surgeons would remove half of a brain hemisphere in a patient with GBM in an attempt to get every last tumor cell. Eventually, surgeons found that method didn’t help: Removing that much of the brain eliminated much of the patient’s abilities and personality, and tumors still eventually grew in the remaining half of the brain. Today, neurosurgeons have to balance on a knife’s edge: They try to remove as much of the tumor as they can while avoiding damage to abilities such as movement, sensation or speech. Computerized brain mapping, much like GPS, makes it possible for surgeons to find their way more accurately.

Performing MRI scans while the patient is still in the operating room (intra-operative MRI) does as well. Stereotactic computerized surgical equipment also improves accuracy. In some cases, surgeons use a local anesthetic so they can perform awake craniotomies, asking for patient feedback as they remove tissue so as to avoid too much damage. And when a tumor recurs, surgeons now can do minimally invasive, MRI-guided biopsies so that the medical team can evaluate whether this is a new tumor or tissue damage from treatment. After surgery, the standard of care in GBM is usually radiation five days a week for five or six weeks. A kind of local radiation, which more precisely targets larger doses of radiation, may be used, such as stereotactic radiosurgery, proton beam therapy or image-guided radiation therapy.

Although results from earlier studies have showed no benefit to continuing radiation beyond six weeks, researchers today are looking at whether new more precise methods can increase the dose or the duration of radiation to better effect. Carmen Mirandola, a sales area manager from suburban Chicago, was on a business trip to Colorado in February 2017 when he suddenly started to have strange symptoms, small seizures and tremors. Colleagues took him to the local emergency department, where a scan found a small mass in the right frontal lobe of his brain. When he returned home, a biopsy confirmed a GBM diagnosis. Mirandola’s surgeon at Northwestern Medicine Central DuPage Hospital was able to remove all of the tumor, often not possible in GBM. After that, Mirandola participated in a clinical trial in which he received proton radiation therapy and Temodar. After more than a year of treatment, he says, his medical team has told him that he may be one of those lucky patients who may survive a decade or more.

“It feels like I’ve been given a second, third and fourth chance. I feel so grateful to Northwestern and my team there,” says Mirandola, 51. “I believe in miracles, the power of prayer and proton radiation.”

Radiation causes DNA damage that leads to the death of tumor cells. Temodar enhances this. Some studies’ findings suggest that radiation doses and timelines can increase as much as 30 percent and improve GBM survival post Temodar. When the timing of radiation and Temodar doses are coordinated, early results from the ongoing CATNON study also showed benefit. Other teams are investigating whether radiation or proton therapy can be used when a GBM tumor recurs.

The FDA has also approved electric field therapy for GBM: Optune is a wearable device that delivers continuous electric pulses to the tumor, through adhesive patches — transducer arrays &mdash; applied to the scalp and connected to the device and a battery. The Optune device must be worn for at least 18 hours a day.

Although FDA approved, Optune remains controversial among neuroscientists. Some sharply criticize the lack of a sham device to the clinical trials that led to its approval. Others say they’re concerned that it remains unclear what biological mechanism makes the treatment work.

“Although trials show some efficacy, most feel that the impact is not dramatic enough that it will become a mainstay of brain tumor therapy,” explains Theodore Schwartz, M.D., professor of minimally invasive neurosurgery at Weill Cornell Medicine in Manhattan.

Further out on the research edge, GBM investigators are trying to determine if an exciting new area of cancer research, immunotherapy, may work for these aggressive brain tumors. Cancer vaccines attack GBM cells by using genetically engineered cells to stimulate the immune system and cause a response. Some teams are looking at chimeric antigen receptor T-cell therapy, which re-engineers a patient’s own immune cells so that they target specific receptors on tumor cells. Other trials are looking at checkpoint inhibitors, which block normal protective proteins on cancer cells, allowing the immune system to target them. So far, trials with checkpoint inhibitors haven’t seemed to make a difference in GBM, but experts say there’s still work to be done here and with Optune.

“There are so many highly trained, smart, qualified researchers devoting their lives to tackle this disease. Patients should feel hopeful,” says Schwartz. “We are making progress. It’s slower than we would like, and patients would like, but look for leaps and bounds of innovation in the coming years.”

Innovations in drug development, surgery, radiation and clinical trials have investigators hard at work in glioblastoma.

Turning the Tide in Glioblastoma

It’s foggy and cool in San Francisco where I live — the curl up and take a nap kind of weather. I feel mostly aches and pains today. But soon, I’m going to push back from my desk, and go to my weekly yoga class.

Exercise may be the last thing on your mind as a cancer patient or survivor, but recently, 25 leading cancer organizations around the globe 

 that exercise be prescribed to all cancer patients as part of their treatment regimen.

You’ve no doubt heard that there’s epidemiological evidence that exercise may protect against cancer recurrence and mortality. But the recent recommendation in the prestigious journal 

 is careful to point out that no evidence to date that proves exercise can improve cancer survival.

From my point of view, exercising is worth the trouble because you’ll feel better if you do. You’ll move more easily, and your mood will probably be more positive—all upsides that 

 cites. When I was in active treatment, my medical team made sure that one of the first appointments I had was with a physical therapist who could help me devise an exercise plan during surgery, chemo and radiation.

My treatment really took it out of me, so the therapist and I decided that daily walks were the way to go. They started out as rigorous hikes. By the last few chemo infusions, I could only manage modest strolls, but I kept doing them. Even as treatment knocked me down, those daily outings helped my mood. They got me out of the house and I think my quality of life was better as a result.

Now several years post-treatment, I am much more active again. I hike, cycle, ski, lift weights and do that yoga class. Has the exercise protected me from a recurrence of my breast cancer? I don’t know, but I do know that I feel better when I do it. Moving my body helps me keep my weight at a reasonable level and improves my sleep and my outlook on life.

Obviously, those of us who’ve experienced cancer have widely different situations and experiences. Some of us are lucky to be able to move easily; others cannot. Some feel energetic; others flattened by treatment and side effects.

I think the key here is that “exercise” does not have to mean that you suddenly become a marathoner or a triathlete. And if you didn’t have an exercise routine before diagnosis, don’t worry or feel guilty. Just move a little more.

Do what you can: That might mean gentle aerobics in a chair or a pool. It might mean something more strenuous, like a kick-boxing class or a run. Do something you enjoy, and start slow. You won’t regret it.

While there has been no hard evidence that exercise can improve survival in patients with cancer, it can boost patients' mood and how they feel.
