Synergistic effect of targeting dishevelled-3 and the epidermal growth factor receptor-tyrosine kinase inhibitor on mesothelioma cells in vitro.

Synergistic effect of targeting dishevelled-3 and the epidermal growth factor receptor-tyrosine kinase inhibitor on mesothelioma cells in vitro. Oncol Lett. 2018 Jan;15(1):833-838 Authors: Moriyama G, Tanigawa M, Sakai K, Hirata Y, Kikuchi S, Saito Y, Kyoyama H, Matsuda K, Seike M, Gemma A, Uematsu K Abstract It was previously revealed that Wnt signaling is activated in mesothelioma cells. Although epidermal growth factor receptor (EGFR) is expressed in mesothelioma cells, EGFR-tyrosine kinase inhibitors (TKIs) are not effective for mesothelioma treatment. However, in non-small cell lung cancer, the blocking of Wnt signaling has been identified to enhance the anticancer effect of EGFR-TKIs. To confirm the anticancer effect of blocking Wnt signaling in combination with EGFR-TKI treatment in mesothelioma, the present study evaluated the effect of simultaneous suppression of human dishevelled-3 (Dvl-3) expression with Dvl-3 small interfering RNA (siRNA) and of EGFR inhibition with gefitinib on mesothelioma cell viability. Mesothelioma cell lines with and without β-catenin gene expression were transfected with Dvl-3 siRNA and were cultured with gefitinib, and cell viability, colony formation and cell cycle analyses were performed. Dvl-3 siRNA downregulated the expression of Dvl-3 in mesothelioma cells. The combination of Dvl-3 siRNA with gefitinib acted synergistically to induce concomitant suppression of cell viability and colony formation, suggesting t...

Cardiac tumors have generally been considered to be rare. They are often found incidentally as they tend to remain clinically silent, but they can sometimes present with symptoms secondary to obstruction, embolization, or invasion of the myocardium. Most cardiac tumors are secondary tumors from metastases, with primary cardiac tumors constituting approximately 15% of all cardiac tumors1. Although melanoma and pleural mesothelioma often have cardiac involvement, the most common cancers to be identified in cardiac metastases are lung cancer (36-39%), breast cancer (10-12%), and hematologic cancers (10-21%)2.

Medical oncologist Dr. Bernardo Goulart at the Seattle Cancer Care Alliance (SCCA) believes his latest clinical trial might be the most curative approach to treatment of pleural mesothelioma. He also believes it could work. Goulart is the principal investigator at SCCA, which has embraced a novel clinical trial that combines the immunotherapy drug Tecentriq (atezolizumab) with a multimodal regimen of chemotherapy, surgery and radiation. “The trial design is very intense, requiring multidisciplinary involvement,” Goulart told Asbestos.com. “I think it could provide insight into the next step of research th...

Not every mesothelioma patient benefits from the immunotherapy drug Opdivo, but for the ones that do, the response can be lifesaving. Opdivo, known generically as nivolumab, continues to produce dramatic results, inching it closer to FDA approval for mesothelioma cancer. A recently published individual case report describes “an exceptional and sustained response.” Treatment with Opdivo allowed one patient to go from a downward spiral, with only weeks to live, back into the workforce. “We were blown away by the patient’s response,” lead author Riley Jones, now in his fellowship at the Universit...

It has been several years since Federal Drug Administration (FDA) approval of a new cytotoxic in thoracic malignancies. Nab-paclitaxel was approved for non-small-cell lung cancer (NSCLC) in 2012, pemetrexed for malignant pleural mesothelioma (MPM) in 2004 and topotecan for small-cell lung cancer (SCLC) in 1998. In the first half of the current decade targeted therapy was the major advancement and in the latter half of this decade immunotherapy has been the focus. Antibody-drug conjugates (ADCs) are a new type of cytotoxic, which target particular cancer cell surface proteins and may aid in stimulating anti-tumor immunity.

For mesothelioma patients, immunotherapy is mostly available through clinical trials at this time. Immunotherapy is a relatively new way to treat cancer, and doctors still are learning who will respond best to these novel therapies. Newly released medical research has found men seem to respond better to immunotherapy than women. But this doesn’t mean immunotherapy is off the table for women with mesothelioma. You should learn all you can about how immunotherapy works, why it may or may not be right for you and how you can best prepare yourself if you decide an immunotherapy clinical trial is right for you. Thorough ...

Authors: Remon J, Mezquita L, Corral J, Vilariño N, Reguart N Abstract Immune checkpoint inhibitors (ICIs) have revolutionized treatment landscape among non-small cell lung cancer (NSCLC) patients in first- and second-line setting, and may become soon new treatment options in other thoracic malignancies such as small cell lung cancer (SCLC) or mesothelioma. The use of these drugs has indubitably changed the toxicity profile the oncologists are familiar with, and new spectra of immune-related adverse events are being reported with the widespread use of immunotherapies in solid tumors. Clinical management and ...

Oncologists in 2019 may begin offering patients with pleural mesothelioma a novel, tumor-fighting tool involving electric currents that enhance standard-of-care treatment and extend survival, according to the device manufacturer. Tumor Treating Fields (TTF) is the name of the new technology. It is designed to disrupt cancer cell division through electric fields tuned to specific frequencies. In an ongoing multicenter phase II clinical trial in Europe, TTF has shown an ability in first-line treatment to improve the effectiveness of standard chemotherapy for mesothelioma patients. The trial success has led the manufacturer t...
