Key Ingredient in Aspirin Could Lead to New Treatment for Mesothelioma
The cancer-fighting properties of aspirin have long been touted. In fact, a daily aspirin may help prevent cancer, according to the American Cancer Society. Now, another study offers more evidence of a positive association between aspirin’s key ingredient, salicylic acid, and its cancer-fighting properties.
In what is encouraging news for mesothelioma patients, researchers report that both aspirin and diflunisal can stop inflammation and cancer. The two nonsteroidal anti-inflammatory drugs (NSAIDs) have the key ingredient salicylic acid that researchers from Gladstone Institutes, of San Francisco, report is effective in inhibiting two proteins, p300 and CREB-binding protein (CBP), preventing cellular damage caused by inflammation. The proteins, according to the researchers, control the levels of proteins that cause inflammation or are involved in cell growth.
“Salicylic acid is one of the oldest drugs on the planet, dating back to the Egyptians and the Greeks, but we’re still discovering new things about it,” said senior author Eric Verdin, MD, associate director of the Gladstone Institute of Virology and Immunology. “Uncovering this pathway of inflammation that salicylic acid acts upon opens up a host of new clinical possibilities for these drugs.”
For people who have previously been exposed to asbestos and face a life-long risk of developing pleural mesothelioma, a cancer of the lining of the lungs, this finding brings hope that the potential for developing the disease could be minimized. Microscopic asbestos fibers when inhaled can lodge in the lungs and remain there causing inflammation that eventually leads to pleural mesothelioma. Many of the cancer treatments are ineffective against the disease, and many experts agree, that the best way to fight the cancer is through prevention.
In the study, the researchers determined that suppressing p300 with diflunisal “stopped cancer progression and shrunk the tumors in the mouse model of leukemia.” The team has also conducted a trial in human hematologic cancers and determined the salicylic acid to be safe. The next step for them is to collaborate in the development of novel epigenetic therapies to find more effective treatment for leukemia patients.
In a separate study in 2015, researchers from the University of Hawaii Cancer Research Center “reported aspirin administration to individuals at high risk of developing MM [malignant mesothelioma], such as those with a history of asbestos …may prevent or delay the growth of MM, possibly increasing life expectancy and also increasing opportunities for early MM detection.”
“The ability to repurpose drugs that are already FDA-approved to be part of novel therapies for cancer patients is incredibly exciting,” said co-author Stephen D. Nimer, MD, director of Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine.
Although evidence may support aspirin use for its anti-cancer properties, doctors stop short of recommending aspirin to prevent cancer. Before starting an aspirin regimen please consult with your doctor.
In the United States, approximately 2,500 to 3,000 people are diagnosed with mesothelioma each year. The disease is incurable, though there are standard treatments to manage the disease including chemotherapy, radiation and surgery.

Mesothelioma Recovery Requires Close Attention to Detail
Mesothelioma is a rare disease and is difficult to diagnose. Once diagnosed, some patients undergo surgery as part of their treatment plan. I’ve found over the years of treating patients after mesothelioma surgery, that there are many extremes in what people think is important, and what they don’t see as important.
Some of the symptoms that you should be aware of are dizziness, persistent coughing (more than you are comfortable with), shortness of breath, weight loss, weight gain (puffiness in your extremities), constipation, pain, weakness (not able to do what you could do a day or two ago), and fever. Paying attention to the way you or your loved one is feeling is important for a smooth recovery. Nutrition is also an important factor to monitor including how much food, and what types of food are being consumed. Also, ensuring the patient is abiding by the fluid intake requirements is important.
Medications and their side effects can also be an issue. When patients leave the hospital after surgery many are on pain medication. As everyone is different, it is important to pay attention to the constipation issue and follow a bowel regime. Often patients are on beta blockers for their heart rate and, sometimes as they get better, the dosages need to be adjusted.
Some of these points seem like they are simple, common sense things. It is surprising, however, how quickly they can escalate into serious issues when they are not addressed. It is important to listen to yourself: if something does not feel right, or if have a question about it, reach out. Call someone on your medical team and get the reassurance that you need.
A successful recovery is a team sport and you are the center of the team! Mesothelioma recovery can be tough, but together with your support system and your mesothelioma team preventable complications can be avoided.

Mesothelioma Patients Should Not Have to Choose Between Hospice Care and Active Treatment
One of the most important things mesothelioma patients and their families cite when it comes to end-of-life care is the desire to be home and with their family. To many in the U.S., this means hospice care and, therefore, the end of active mesothelioma cancer treatment. Now, researchers point to a model adopted by the U.S. Veteran’s Administration where hospice and active cancer care are given concurrently.
Hospice is designed to improve the quality of a patient’s last days by offering comfort and dignity, and often allows the patients to remain in their own home surrounded by their loved ones. Today, once hospice is established in the U.S. active cancer care is ended and the patient receives palliative care that is intended to control pain and relieve mesothelioma symptoms.
According to Drs. Jeanie M. Youngwerth and D. Ross Camidge from the University of Colorado, the U.S. trails behind many other countries when it comes to providing quality medical care for patients with terminal conditions. But, straying from the norm, the VA does not limit “curative” therapies while a veteran is receiving hospice care.
“Consequently, in theory, the VA would permit life-prolonging measures, such as chemotherapy, to be administered while a patient simultaneously receives hospice services,” said the doctors.
For veterans, this is good news since this population makes up one-third of those who suffer from mesothelioma, a terminal cancer caused by past asbestos exposure. Approximately 3,000 Americans are diagnosed with mesothelioma each year. Asbestos was used as insulation in military buildings and ships. It was also used as an insulator around heat and cooling systems, in Navy vessels and in the gaskets placed inside airplane engines and large machinery.
For other mesothelioma patients, the option for concurrent care is still being assessed. The doctors point out that several clinical trials found “ early initiation of palliative/hospice care with active anti cancer therapy, so called “concurrent care,” improves quality and, potentially, quantity of life for patients with advanced cancer.” In addition, they note, that a 2010 study found that “patients with advanced lung cancer did better in terms of both quality and quantity of life when they received palliative care integrated with standard anticancer care as opposed to receiving anticancer care alone.”
Other government agencies hope to join the VA in their treatment model. Centers for Medicare & Medicaid Services, through the Medicare Care Choices Model, is piloting a program for Medicare beneficiaries to receive palliative care services from certain hospice providers while concurrently receiving anticancer therapies provided by their oncology providers, according to the doctors.
Other medical professionals agree with the need for concurrent care for critically ill patients. In a 2012 presentation at the annual meeting of the American Academy of Hospice and Palliative Medicine, Dr. Diane E. Meier, director of the Center to Advance Palliative Care and professor of geriatrics and internal medicine at Mount Sinai School of Medicine, stressed that now is the time to educate physicians as well as the general public that palliative care is “actually about relieving the pain, symptoms, and stress of serious illness in patients of any age and at any stage of disease, and that palliative care can be delivered alongside curative or life-prolonging therapies.”

Protein Could Be Used to Develop Mesothelioma-Fighting Drug
Researchers report they have found an effective way to induce apoptosis, or cell death, and to suppress cancer growth. The team is targeting the BaK protein and has found a way to transform it “into a killer protein” that kills cancer cells. The hope is that this approach will lead to developing drugs that will be effective in fighting treatment-resistant cancers like mesothelioma.
Mesothelioma, an asbestos-caused cancer, like many cancers, is resistant to standard treatments, and, thus, to apoptosis. Apoptosis is often referred to as cell suicide because when cells are damaged they sacrifice themselves to prevent damaging additional cells. However, in cancer, the process goes amok and the diseased cells continue to divide and grow.
According to researchers from the Walter and Eliza Hall Institute of Medical Research, of Melbourne, Australia, the BaK protein, which is central to apoptosis, is present but inactive in healthy cells. But when a cell receives the trigger to die, BaK is activated and helps destroy the cell. In cancer cells that are notorious for tricking the body’s natural defense mechanisms, however, BaK is not activated and apoptosis does not occur leaving the cells unchecked.
The researchers set out to find a way to mimic the action of BaK, or to turn on the trigger to kill cancer cells. They inadvertently found an antibody they were using to simply study BaK, actually bound to the protein and triggered its activation.
“There is great interest in developing drugs that trigger Bak activation to treat diseases such as cancer where apoptosis has gone awry,” said Dr. Ruth Kluck, BSc, PhD, QLD, lead researcher and Laboratory Head of the Molecular Genetics of Cancer. “This discovery gives us a new starting point for developing therapies that directly activate Bak and cause cell death.”
In fact, the researchers are already collaborating with others to develop their antibody into a drug that can take advantage of the BaK protein.
Finding an effective way to prevent cancer cells from evading cancer death by artificially triggering it could increase the efficacy of existing treatments leading to increased survival in mesothelioma patients. Mesothelioma is diagnosed in nearly 3,000 Americans each year, and the same number die from the cancer.

Mesothelioma Patients Need More Information to Help Make Treatment Decisions
When patients are faced with a life-threatening illness like mesothelioma, the more information they have the less anxious they feel about the diagnosis. Unfortunately, according to a recent study, terminally ill patients lack even basic information about their illness.
In a study conducted by a research team from Weill Cornell Medicine in New York City, led by Dr. Holly Prigerson, professor of geriatrics, researchers report that of 178 patients who were faced with highly lethal metastatic cancers, just five percent of the patients had “sufficient knowledge about their illness to make informed decisions about their care.”
“Many did not know that they were at the end-stage of their illness or that their cancer was incurable. They were basically making treatment decisions in the dark,” explained Prigerson, who also co-directs the Center for Research on End-of-Life Care at Weill Cornell.
Treatment for mesothelioma, a terminal asbestos-caused cancer, can vary from patient to patient. Primarily, treatment options consist of surgery, chemotherapy and radiation. It is critical for the patients, however, to understand their prognosis and the benefits and risks associated with each of these options to ensure they are prepared for the arduous battle ahead.
According to the researchers, doctors are reluctant to share information about terminal illnesses for fear that they will upset the patients or the patients will view the doctor less favorably. Without the information, though, many patients have a false sense of security and do not even realize they have limited survival.
The researchers concluded that patients who have discussions with their oncologists about prognosis and life expectancy “come to have a better understanding of the terminal nature of their illnesses.” They added that improvement in the area of end-of-life patient/doctor communication can improve patient-centered care.
This research points to the fact that the more knowledge patients have about their illness, the better off they are when it comes to making their own treatment decisions. In fact, previous research has pointed out that an empowered mesothelioma patient is often the best patient for a medical team. When patients are empowered it means they are informed of their disease and their treatment options, and they are willing to take an active role in their treatment.
Managing a disease such as mesothelioma can be overwhelming, but partnering with your physician from the start may be the key to receiving the best treatment. According to a 2002 article on patient empowerment in the Hong Kong Medical Journal, researchers said, “Medical knowledge has long been used in clinical practice for professionals. It is time to shift the balance of power to include patients and their caregivers.”
The study was published the May 23 edition of the Journal of Clinical Oncology.
