Tumor Treating Fields Showing Early Success for Mesothelioma

Dr. Giovanni Ceresoli doesn’t think Tumor Treating Fields will work for every patient with mesothelioma cancer, but he knows it will work for some. They are in his clinic. As the principal investigator of the multicenter clinical trial that led to approval by the U.S. Food and Drug Administration in May, Ceresoli has played a major role in the development of this latest mesothelioma treatment. “It might be too early to say this is a major breakthrough — we need more data — but I hope it is. I know it’s something promising, very promising,” Cerosoli told The Mesothelioma Center at Asbestos.com. “I can say that based on what we’ve seen.” Tumor Treating Fields, which works in synergy with chemotherapy, is designed to disrupt cancer cell division through electric fields tuned to specific frequencies. Cerosoli is section manager in the Department of Oncology at Cliniche Humanitas Gavazzeni in Bergamo, Italy, one of 12 sites across Europe that conducted the study called STELLAR. The phase II trial involved using the combination of chemotherapy and the NovoTTF-100L System. The device is manufactured by Novocure, a global oncology company based in the United Kingdom with operations in Australia, the United States, Japan and Switzerland. Study results were released in 2018 and included one- and two-year survival rates of 62.2% and 41.9%, respectively. The FDA approved it for first-line treatment under its Humanitarian Device Exemp...

An international team of pathologists has identified a new protein often found on pleural mesothelioma tumor cells. The discovery could lead to a more accurate prognosis for patients and future treatment advances. Researchers found for the first time that mesothelioma patients expressing higher levels of the CD70 protein typically experience a much shorter survival, regardless of cell type or treatment type. “These markers might be useful for MPM [malignant pleural mesothelioma] prognostic evaluations, as well as targeted therapeutics,” the study authors wrote. “Further analyses in syngeneic mouse models...

The Miami Cancer Institute on Thursday will begin using the innovative Tumor Treating Fields device for patients with malignant pleural mesothelioma. It is the first new treatment approved for mesothelioma by the U.S. Food and Drug Administration in more than 15 years. “This is actually pretty exciting for us,” Dr. Rupesh Kotecha, the radiation oncologist who will oversee the treatment protocol in Miami, told The Mesothelioma Center at Asbestos.com. “It’s another tool in our armamentarium. It’s something we can offer patients that has shown a real benefit.” The noninvasive Tumor Treating...

Authors: Sano M, Kaneko MK, Kato Y Abstract The highly O-glycosylated membrane glycoprotein podoplanin (PDPN) is frequently overexpressed in several malignant cancers, such as oral cancer, lung cancer, germinal neoplasia, mesothelioma, and brain tumor. The expression of PDPN is strongly associated with cancer progression and poor prognosis. PDPN possesses three tandem repeats of platelet aggregation-stimulating (PLAG) domains (PLAG1, PLAG2, and PLAG3) and PLAG-like domain (PLD), and binds to C-type lectin-like receptor 2 (CLEC-2) on platelets, followed by PDPN-mediated platelet aggregation. We have previously estab...

The contribution of the complement system in the pathophysiology of brain cancers has been recently considered in light of its well-known involvement in carcinogenesis. Complement system represents an important component of the inflammatory response, which acts as a functional bridge between the innate and adaptive immune response. C1q, the first recognition subcomponent of the complement classical pathway, has recently been shown to be involved in a range of pathophysiological functions that are not dependent on complement activation. C1q is expressed in the microenvironment of various types of human tumors, including mel...

A mesothelioma patient at West Cancer Center in Memphis, Tennessee, is the first in the country to use NovoTTF-100L, a noninvasive electric therapy treatment, since its approval by the U.S. Food and Drug Administration in May. The FDA’s approval of Novocure’s Tumor Treating Fields device for the treatment of mesothelioma marked the first new FDA-approved treatment option for the rare asbestos-related cancer in more than 15 years. NovoTTF-100L uses a low-voltage electrical field that is distributed with three pads attached to the front and back of a person’s chest. The electrical current is designed to di...

To the Editor I read the article by Perry et al with interest. Several other molecular mechanisms and factors may also play a role in how anesthesia may influence cancer outcomes. First, it is important to distinguish the difference between certain fluoridated anesthesia, such as sevoflurane, from their contribution to higher plasma fluoride levels. For example, it is known that sevoflurane can provide 20-fold the total daily dietary fluoride intake from all sources of fluoridated food and water combined, resulting in peak ionic fluoride levels in the range of 50 μmol/L. Hence, fluoridated anesthesia can result in extre...

Abstract Recent reports describe how genome-wide transcriptional analysis of cancer tissues can be exploited to identify molecular signatures of immune infiltration in cancer. We hypothesize that immune infiltration in cancer may also be defined by changes in certain epigenetic signatures. In this context, a primary objective is to identify site-specific CpG markers whose levels of methylation may be highly indicative of known transcriptional markers of immune infiltration such as GZMA, PRF1, T cell receptor genes, PDCD1, and CTLA4. This has been accomplished by integrating genome-wide transcriptional expression a...

The U.S. Food &Drug Administration on Thursday approved Tumor Treating Fields, a therapy involving electric currents that disrupt cancer cell division and inhibit tumor growth, for the first-line treatment of malignant pleural mesothelioma. It is the first treatment in more than 15 years that the FDA approves for mesothelioma. In 2004, the agency added the chemotherapy drug pemetrexed (Alimta) to standard-of-care treatment. The FDA approved Novocure’s NovoTTF-100L System under the agency’s Humanitarian Device Exemption. The approval comes eight months after Novocure, which manufactures and markets the devi...

Conclusions This review describes how leukocyte-heparanase can be a double-edged sword in tumor progression; it can enhance tumor immune surveillance and tumor cell clearance, but also promote tumor survival and growth. We also discuss the potential of using heparanase in leukocyte therapies against tumors, and the effects of heparanase inhibitors on tumor progression and immunity. We are just beginning to understand the influence of heparanase on a pro/anti-tumor immune response, and there are still many questions to answer. How do the pro/anti-tumorigenic effects of heparanase differ across different cancer types? Does...

This study hypothesized that similar VOCs might be detected after HBOT. Methods: Ten healthy volunteers of the Royal Netherlands Navy underwent six HBOT sessions (95 min at 253 kPa, including three 5-min “air breaks”), i.e., on five consecutive days followed by another session after 2 days of rest. At 30 min before the dive, and at 30 min, 2 and 4 h post-dive, exhaled breath was collected and followed by PFT. Exhaled breath samples were analyzed using gas chromatography-mass spectrometry (GC-MS). After univariate tests and correlation of retention times, ion fragments could be identified using a reference data...
