Is Watson the Best Approach for Determining Treatment Plans?
Five years ago Watson debuted on Jeopardy! in a matchup with two of the winningest contestants from the show, Ken Jennings and Brad Rutter. Watson proved why he is a “supercomputer” by handily beating the two at the game. At the time, not many of the viewers envisioned that IBM’s artificial intelligence machine would someday be important to their healthcare. Now, Watson is mainstream in TV commercials asking viewers, “How can I help you?” For a mesothelioma patient, the answer might be, “Find the most effective treatment for me.”
Thanks to a partnership between New York’s Memorial Sloan Kettering Cancer Center (MSKCC) and IBM, Watson Oncology may soon be the go-to reference for oncologists, helping drive cancer care for all patients. Watson Oncology’s primary strength lies in the massive database fed with data from MSKCC on how their doctors treat their cancer patients. While this amount of data is nearly impossible for a doctor to analyze, Watson analyzes and assesses the information quickly, placing incredible knowledge at the doctors fingertips. For patients suffering from mesothelioma, a rare, aggressive cancer with few treatment options, Watson might just be the only way to guide oncologists to finding the best evidence-based treatment protocol.
“We are training Watson so oncologists anywhere will be able to make more specific and nuanced treatment decisions more quickly, based on the latest data,” said an MSKCC spokesperson in response to a comment in an article about Watson.
What is Watson Oncology?
Watson is the result of four years of hard work in IBM’s Grand Challenge: “Can a system be designed that applies advanced data management and analytics to natural language in order to uncover a single, reliable insight in a fraction of a second?” Using Jeopardy! as the ultimate test required IBM to build a machine that can interpret natural or human language that relies on the ability to relate pictures, phrases, figures, slang and nuances.
Since then, Watson has grown into a tool and resource for businesses worldwide. When MSKCC oncologist Mark Kris, MD, William and Joy Ruane Chair in Thoracic Oncology at MSKCC, realized the potential Watson could have on patient care, he led a team to build a database for Watson Oncology that could “revolutionize care and research, accelerating progress for people with cancers.”
MSKCC uses their “world-renowned cancer expertise” to drive Watson Oncology to give oncologists access to “individualized treatment options that are informed by medical evidence and our highly specialized experience.”
“I think this is beyond an evolutionary step,” says Dr. Larry Norton, Deputy Physician-in-Chief for Breast Cancer Programs, MSKCC. “I think this is a revolutionary step.”
In addition to MSKCC’s work with Watson, IBM and MD Anderson Cancer Center have also partnered. The partnership builds on MD Anderson’s oncologists’ knowledge to help drive the center’s Moon Shots program with a goal to “rapidly and dramatically reduce mortality and suffering in cancer.” In much the same as MSKCC’s Watson Oncology, MD Anderson’s Oncology Expert Advisor is expected to provide the medical team “with immediate, worldwide access to MD Anderson’s expertise and resources, and to IBM Watson’s technology prowess in quickly extracting crucial insights from large volumes of complex data.”

Watson and Mesothelioma
Having what could become a nearly infinite volume of information instantly available makes Watson incredibly valuable. Using computers to help identify how to treat a complex medical condition, like mesothelioma, can improve survival and the patient’s quality of life. Having the information built by two of the most renowned mesothelioma centers in the world, can only mean excellent care for mesothelioma patients.
MSKCC is the world’s oldest and largest private cancer center, and has a team of specialists including surgical oncologists, medical oncologists, radiation oncologists, pathologists, and nurses who deal exclusively with mesothelioma and other thoracic cancers. They are committed to providing the best possible treatments for patients with malignant pleural mesothelioma, and often conduct clinical trials and studies for mesothelioma as they continue to make strides in the treatment of the deadly disease.
The University of Texas M.D. Anderson Cancer Center works hard at achieving their vision of being the “premier cancer center in the world” through their initiatives in the research and treatment of mesothelioma. The cancer center has over 30 specialists on staff that supports their multi-disciplinary approach to treating mesothelioma patients. Their ongoing research and unique initiatives dedicated to finding a cure for mesothelioma makes them one of the few cancer centers in the world with a comprehensive program.
“Cognitive computing in healthcare allows us to use every step, every heartbeat, every checkup, every gene, every prescription,” according to IBM. “IBM Watson Health is helping transform healthcare and leading us to new insights. Helping keep us all healthier.”

Researchers Find New Way to Treat KRAS Lung Cancer
In March, MesotheliomaHelp reported that two drugs may be better than one when it comes to treating KRAS-positive lung cancer patients. Now, in a new study, researchers report they have found yet another way to tackle lung cancer when the KRAS gene is present.
In a July 28 press release from UT Southwestern, researchers report that the Kirsten rat sarcoma viral oncogene homolog (KRAS) gene, that is responsible for the most aggressive subtype of non-small cell lung cancer (NSCLC) and is found in nearly 30% of all NSCLCs, controls cell division and can drive healthy cells to divide uncontrollably, leading to cancer. The gene is tough and it nearly always fights off treatments building resistance to the drugs.
“Mutant KRAS not only promotes the growth of tumors, but also the survival of established lung cancer,” said Dr. Scaglioni, who leads the Cancer Signaling Laboratory at the Simmons Cancer Center. “Since we have no clinically-relevant effective inhibitors of mutant KRAS at this time, there has been an intense clinical interest in developing a treatment that is proven effective.”
In order to influence the effects of KRAS, the researchers realized they needed to target the ACSL3 gene. The researchers found that it is the ACSL3 gene that keeps cancer cells alive, yet when suppressed, the gene is responsible for cell death. They also found that the ACSL3 gene is “highly expressed” in lung cancer, thus making it critical to find a way to suppress it.
The scientists tested the impact of the ACSL3 gene in the lab using mice and on a human KRAS-positive NSCLC line. In both cases, the researchers proved that “ACSL3 silencing was accompanied by induction of apoptosis,” or cell death. They propose that, “ACSL3 is a target for the development of targeted therapies against mutant KRAS lung cancer.”
“There is an urgent need for discovery of additional targets that inhibit lipid metabolism in cancer cells that could lead to targeted therapies: the discovery of the importance of ACSL3 in lung cancer meets this unmet need,” said Dr. Mahesh S. Padanad, first author of the study.
Although the research was focused on lung cancer, every new breakthrough in cancer research brings hope to mesothelioma patients. Pleural mesothelioma, an asbestos-caused cancer equally as aggressive as NSCLC, is diagnosed in close to 3,000 Americans each year. Currently, there is no cure for the disease and treatments are often considered palliative.
The study was published in the July 26 issue of Cell Reports.
IBM’s Lab-On-A-Chip Offers Potential for Early Diagnosis
Lab-on-a-chip technology has been in the news since at least 2012 when researchers at Harvard announced their plans to ultimately create a human-on-a-chip. Since then, other research institutes have tackled the chip technology to create a way to mimic the human organs and to detect and track cancer. Now, IBM has announced it has created a chip that can detect “cancer before symptoms appear.”With no reliable technology yet available to detect mesothelioma asbestos cancer early, the mesothelioma community is keeping a close eye on this latest breakthrough.
According to an Aug. 2 article in Phys.Org, years of work by IBM researchers has culminated in development of a new lab-on-a-chip technology that can separate bioparticles down to nanometers – which are one-billionth of a meter – which then allows access to DNA and exosomes. Exosomes are biomarkers that are the core of cancer research, found in bodily fluids such as blood, saliva or urine, and according to the researchers, “can be used in the context of less invasive liquid biopsies to reveal the origin and nature of a cancer.”
“The ability to sort and enrich biomarkers at the nanoscale in chip-based technologies opens the door to understanding diseases such as cancer as well as viruses like the flu or Zika,” said Gustavo Stolovitzky, Program Director of Translational Systems Biology and Nanobiotechnology at IBM Research, in an Aug. 1 press release from IBM. “This extra amount of time could allow physicians to make more informed decisions and when the prognosis for treatment options is most positive.”
By looking closely at the exosomes and assessing the surface proteins, and other critical information, researchers can find “essential information about the presence and state of developing cancer and other diseases.” The technology can decipher cell-to-cell communications which, when monitored, can track a patient’s health and the progression of the disease.
Pleural mesothelioma, a cancer of the lining of the lungs, is a very aggressive cancer that is often not diagnosed until the patient has developed life-threatening complications. At this point, mesothelioma treatment options are palliative and may help relieve symptoms but do not typically extend survival.
“When we are ahead of the disease we usually can address it well; but if the disease is ahead of us, the journey is usually much more difficult,” said Dr. Carlos Cordon-Cardo, Professor and Chairman for the Mount Sinai Health System Department of Pathology.
IBM and a team of researchers from the Icahn School of Medicine at Mount Sinai are now collaborating and will move forward to test the technology on prostate cancer.
The study can be found in the Aug. 2 issue of Nature Nanotechnology.

Signaling Protein Could Lead to New Mesothelioma Treatment
Researchers continue to be confounded by the ability of mesothelioma cells to outfox even the most toxic of anti-cancer treatments. Regardless of the therapy used, the cancer almost always recurs locally. Now, researchers focusing on the P2X7 receptor, that allows cancer cells to communicate, may have found a new target for treating mesothelioma.
Tumors use a complex communication mechanism, known as pathways, to promote their survival. Whereas apoptosis, the natural process whereby damaged cells naturally die, should keep illness at bay, a defect in this process can lead to uncontrolled mesothelioma growth. The P2X7 (P2RX7 or P2X7R) purinergic receptor, or signaling pathway, has been gaining attention due to its involvement in cancer cell death or proliferation.
Researchers from University of Ferrara, Italy have also turned their mesothelioma research focus to the proteins. They found that the P2X7R protein was overexpressed in three different mesothelioma lines derived from previously diagnosed mesothelioma patients. But, they found that the protein was not present in mesothelial cells from healthy patients.
The researchers introduced selective P2X7R inhibitors to the mesothelioma cells and were able to halt the growth of the mesothelioma cells. They then tested the inhibitors on mice with mesothelioma tumors by implanting them under the skin and in the peritoneal cavity. Once again, the treatment resulted in a reduction of tumor growth.
“Our findings suggest that the P2X7R might be a novel target for the therapy of mesothelioma,” concluded the researchers.
Mesothelioma is diagnosed in close to 3,000 Americans each year. Currently, there is no cure for the cancer although patient survival and quality of life can be improved through surgery, radiation and chemotherapy. For patients receiving targeted care, their treatment protocol is often driven by the presence of the cancer’s unique biomarkers.

New Research Found to Halt Lung Cancer Brings Hope
Lung cancer and pleural mesothelioma are two highly aggressive cancers that are typically diagnosed in a late stage leaving patients with few treatment options. Countless hours of research have been spent on identifying biomarkers or genes that can be targeted to put a halt to the insidious cancers, in the meantime the two cancers continue to take their toll on patients. Now, in a newly released study, researchers report they may have found a way to stop the development of lung cancer.
In an Aug. 5 press release from the Cancer Science Institute of Singapore (CSI Singapore) at the National University of Singapore (NUS), researchers reported that by inhibiting the BMI1 protein they could impair tumor growth in lung cancer. Subsequently, the team found that C/EBPα, an important tumor suppressor, has close ties to BMI1, responsible for both tumor growth and survival, and looking at the interaction of the two markers could lead to a novel treatment for lung cancer.
The team of researchers, led by Professor Daniel Tenen, Director of CSI Singapore, discovered that certain non-small cell lung cancers expressed low levels of C/EBPα resulting in poorer survival when a corresponding high expression of BMI1 also existed.
“This study has established an important link between C/EBPα and BMI1 for the first time,” said Prof Tenen. “Furthermore, these findings suggest that assessment of expression levels of these proteins could be used as a way to predict which patients might benefit from drugs which inhibit BMI1, some of which are currently being evaluated in clinical trials.”
Pleural mesothelioma is a rare, serious cancer affecting the lining of the lungs that occurs in individuals exposed to airborne asbestos fibers. Although pleural mesothelioma is distinguished by a large mass of interlocked tumors that blend in with healthy tissue, lung cancer is characterized by more distinct, individual tumors. Despite the differences, any research leading to new treatment for lung cancer brings hope to all of the mesothelioma community.
Nearly 3,000 Americans are diagnosed with mesothelioma each year. The same number succumb to the incurable cancer.
“Therefore, anti-BMI1 pharmacological inhibition may offer a therapeutic benefit for lung cancer patients with low expression of C/EBPα and high BMI1,” concluded the researchers.
The study can be found in the Aug. 3 issue of Science Translational Medicine.
