What Would Dad Think of the Mesothelioma Ups and Downs?
In the years that have passed since I lost my father to mesothelioma, I have often looked at events, not only in my life and immediate community, but also globally, and wondered, what would Dad think about this? Sometimes, they are lighthearted happenings, others, more sober topics; Dad was interested in most things and I loved hearing his opinions and simple wisdom applied to anything and everything.
If Dad were to look at the advocacy that his family continues with the mesothelioma community, I think he would be proud. His smile beaming, eyes sparkling, as they did any time someone did something that he thought was admirable and good. He was an advocate with us before he lost his fight, and I know that he was excited to continue on with his work; now it continues through those who love him.
If my father saw the success that some friends are having with their mesothelioma treatments, he would be ecstatic, praising God and congratulating them on their progress. To see the other side, however, the number of those who have since passed, his heart would be broken and he would be working to console their families.
Seeing the recent revelations about asbestos being used in children’s make up, I know that he would have been so sad. Dad loved children and the thought of a child being exposed to something so life-shattering would cause his heart great pain and sorrow. I’m sure that he would have had some strong feelings of how this should be handled.
I think about Dad every second of every day. Still, four years later, I find myself picking up the phone to call and tell him about something going on that I know would interest him. Even though he can’t pick up, I do take time to think about what his reaction would have been. This is a practice that keeps his memory alive in my heart, and I know that he smiles knowing that I’m still thinking about the wisdom he imparted on me and my family.
Breakthrough Blood Test May Extend Mesothelioma Survival
Just last week, MesotheliomaHelp reported on a corporate partnership for blood test tools that will bring improved results in the detection of key lung cancer mutations. Blood biopsies are shown to be fast and accurate, as well as less stressful on the patients. Now, in another breakthrough using liquid biopsies, researchers report success in the early detection of mesothelioma and screening for multiple cancers using one tool.
Researchers from Johns Hopkins University have developed the CancerSeek blood test that is able to screen for eight different types of cancers and can help pinpoint the location of the tumor. In a recent study of 1,005 cancer patients, the results had a “greater than 99 percent specificity for cancer,” according to a Jan. 19 press release from Johns Hopkins University.
[expert_info author=”Bert Vogelstein, Johns Hopkins University”]”This test represents the next step in changing the focus of cancer research from late-stage disease to early disease, which I believe will be critical to reducing cancer deaths in the long term.”[/expert_info]Although there are screening options for some cancers, such as breast and prostate, mesothelioma, and many other cancers, are diagnosed after the patient goes to a doctor exhibiting some of the signature symptoms of cancer: unexplained weight loss, extreme fatigue and a persistent cough. CancerSeek results had a sensitivity ranging from 69 percent to 98 percent in five cancers that do not currently have any screening test availables, including ovarian, pancreatic, and esophageal cancers.
The test, according to the researchers, looks at eight common cancer proteins and the presence of cancer gene mutations from DNA circulating in the blood. The team developed a “small yet robust panel” that could detect at least one mutation and not lead to false-positives. The test is used for cancer detection only, and does not detect specific biomarkers to drive treatment.
“The use of a combination of selected biomarkers for early detection has the potential to change the way we screen for cancer…,” says Nickolas Papadopoulos, senior author and professor of oncology and pathology at Johns Hopkins.
Pleural mesothelioma, a deadly cancer of the lungs caused by past exposure to asbestos, has a long incubation period where patients may not exhibit symptoms for decades after exposure. By then the disease is already at an advanced, incurable stage.
Early detection of cancer through screening reduces mortality from many cancers, including lung and colon, according to the National Cancer Society. When treating mesothelioma patients, the best outcome is achieved with early detection of the disease by increasing treatment options and improving the patients’ quality of life while battling the cancer.
The tests are still in the early stages of research and are not yet available; however, they may be helpful in diagnosing mesothelioma in the future. In fact, the team anticipates a relatively inexpensive test that may be conducted by a primary care provider.

Turning Off Certain Enzymes Could Stop Mesothelioma Growth
Researchers realize that one of the best ways to fight cancer is to stop it from growing and metastasizing in the first place. However, finding the right way to do that is not easy. Now, researchers believe that by turning off certain enzymes they can stop cancer cells from dividing. This discovery may stop cancer in its tracks, and bring new treatments that could extend the lives of mesothelioma patients.
Researchers from Uppsala University, Karolinska Institutet, and the University of Oxford, began to look deeper into finding a way to switch off enzymes as a promising strategy to fight cancer. Tailored drugs are needed to shut down an individual enzyme, but before they could look at new therapies, they needed to better understand how cancer-fighting drugs get to their targets.
The team of scientists turned their focus deep into the cells to a cell membrane protein dehydroorotate dehydrogenase (DHODH), a key anticancer target known to play a role in cell proliferation, according to a Jan. 19 press release from Uppsala University. They conducted a series of tests to determine how lipids, or building blocks of the cell membrane, and drugs bind to the DHODH enzyme. By better understanding this mechanism, they can better understand how to drive drugs directly to the disease.
“To our surprise, we saw that one drug seemed to bind better to the enzyme when lipid-like molecules were present,” says assistant professor Michael Landreh, Karolinska Institutet. In addition, they found that a lipid present in the mitochondrial respiratory chain complex, or the cell’s energy source, binds to the enzyme. The researchers concluded that DHODH may “use special lipids to find its correct place on the membrane.”
Research suggests that tumor metastases are responsible for approximately 90% of all cancer-related deaths. Funding research to find ways to have drugs home in directly on the disease brings hope to every cancer patient. In the case of mesothelioma, an incurable, asbestos-caused cancer, that quickly spreads to other organs leaving patients with few treatment options, halting cancer growth could lead to extended survival. Survival is typically about one year.
“By studying the native structures and mechanisms for cancer targets, it may become possible to exploit their most distinct features to design new, more selective therapeutics,” says Sir David Lane, Karolinska Institutet.

After Losing Father to Mesothelioma, Mother Finds It “Unspeakable” That Asbestos Is Found In Children’s Makeup
As a mother, I worry. I worry about my daughter’s first day of school; will she be nervous? I wonder what the world will be like for her as she grows and moves into adulthood. I wonder what she will decide to be when she grows up, who will she grow up to be? Something that I never considered worrying about until my father got sick was the danger of asbestos.
Sure, we know that asbestos is found in building products and things of that nature, but it being used in children’s crayons and makeup? It is completely unspeakable and inexcusable. Why would a company knowingly place our youth in danger, all for the sake of making a dollar?
Yes, I know that the products have been removed from the shelves, but who is to say that there aren’t more items like these still out there, let alone the damage that may have already been done? Thinking about what these children may end up going through because they colored a picture or played dress up makes me angry and sick to my stomach.
It’s time that we all stand up to the companies endangering society at large, especially those targeting our children. It is not okay to ignore the deadly implications of asbestos, enabling more and more of us to be put, unknowingly, at risk.
Take the time to look at ingredients of items you may use every day. If it’s questionable, put it back, call the company and demand answers. You owe it to yourself and to future generations to stop this cycle and help to eradicate the use of asbestos, and, in turn, mesothelioma.
Chemical in Alaskan Sea Sponge May Kill Mesothelioma Cancer Cells
Another sea-dwelling plant is making headlines in oncology research. Over a year ago MesotheliomaHelp reported that the active agent, trabectedin, found in the Caribbean sea cucumber showed promise in fighting mesothelioma. Now, researchers believe the unique chemical composition in the deep-water Alaska green sponge could kill cancer cells. This discovery could lead to treatments for pancreatic cancer, and other aggressive cancers such as mesothelioma.
Found by National Oceanic and Atmospheric Administration (NOAA) scientist Bob Stone in 2005 during a fishery mission, the sponge has researchers from around the U.S., and the globe, clamoring to find out more about it, according to a July article in NOAA Fisheries. A researcher from the Medical University of South Carolina, who has been turning to marine life as a potential drug ingredient for nearly 20 years, is particularly excited by the discovery and is now working with Stone, a team in New Zealand, and with other cancer centers in the U.S.
Identifying the sponge as Latrunculia austini, Mark Hamann, the Charles and Carol Cooper SmartState Endowed Chair at MUSC, said that the plant, “covers unique and unprecedented chemical space.”
Samples of the sponge are now in the hands of researchers at the Henry Ford Cancer Institute where a team is testing sponge extracts against pancreatic cancer cells. The researchers found the green sponge extracts effective in killing pancreatic cancer cells in the lab.
“You’d never look at this sponge and think this is a miracle sponge, but it could be,” said Stone.
Although pancreatic cancer and mesothelioma are very different cancers, the two diseases both lack treatments that can effectively combat the tumors. Chemotherapy is a standard treatment option for both mesothelioma and pancreatic cancer, but eventually the cancer cells build up a resistance to the treatment. Survival is low for both cancers.
The cancer-fighting capability of the sponge is driven by its inability to flee from predators. As a result, it builds up powerful chemicals to ward off its enemies. For that reason, Hamann and the other researchers turn to these marine creatures to develop life-saving drugs. They note that “Of the eight most frequently prescribed products to treat cancer, half are natural products.”
The sponge is at a depth that makes it difficult to harvest bringing a significant obstacle to the research, albeit one worth trying to overcome. “For pancreatic cancer this is absolutely the best lead that we have,” Hamann said.
Mesothelioma, caused by asbestos exposure, is diagnosed in close to 3,000 Americans each year. Currently, there is no cure for the disease, but research into treatments of other cancers is followed closely by the mesothelioma community in hopes the results are transferrable.
“Given the lack of current effective drug treatments available for pancreatic cancer, this study finding offers hope for the future of cancer care,” said Fred Valeriote, senior researcher with the Henry Ford Cancer Institute.
This research is in early stages and significant, additional research is still needed.
