    Immune Checkpoint Inhibitors for Recurrent Mesothelioma: Early Adoption Gave Them Traction

    ByAlex Strauss

    A new report shows that doctors started using immune checkpoint inhibitors for recurrent mesothelioma at least two years before the practice was officially sanctioned. This early adoption gave ICIs traction to quickly become part of clinical practice.  Immune checkpoint inhibitors block mesothelioma’s built-in resistance to immune system attack. They are among the most promising approaches to combating this intractable cancer.  University of Pennsylvania researchers recently ran a retrospective study on immune checkpoint inhibitors for recurrent mesothelioma. The study looked at real-world mesothelioma patients at several different medical centers. The researchers found that, even though the National Comprehensive Cancer Network (NCCN) did not revise it’s guidelines to include immune checkpoint inhibitors as a second-line treatment until 2017, doctors were using them…

    Yervoy and Opdivo for Mesothelioma: Three Year Results Still Look Good

    ByAlex Strauss

    Three years after the last patients enrolled in the clinical trial of Yervoy and Opdivo for mesothelioma, survival results still look promising for this immunotherapy treatment.  Researchers presented an update of the CheckMate 743 trial at the recent virtual conference of the European Society for Medical Oncology (ESMO). The team found that more than 23% of patients on Yervoy and Opdivo for mesothelioma were still alive at three years. Only 15% of the chemotherapy group were still living.  Immunotherapy for Malignant Mesothelioma Alimta (pemetrexed) was the first drug to receive FDA approval for mesothelioma chemotherapy. The FDA approved it in 2004.  Before Alimta, patients had even fewer options that they do today. Most mesothelioma patients now start treatment with a…

    CT Evaluation Correlates with Actual Mesothelioma Tumor Volume, Subtype, and Survival

    ByAlex Strauss

    Two new studies highlight the value of CT evaluation for patients with either peritoneal or pleural mesothelioma.  CT stands for computed tomography. The technology uses X-rays to create three dimensional images of internal structures.  The studies show CT evaluation can give doctors an accurate idea of the size and extent of mesothelioma tumors. These scans can also help predict which patients have the best odds of survival. This helps doctors plan better, more effective treatment strategies.  What is Malignant Mesothelioma? Malignant mesothelioma is a type of cancer that grows on the membranes around internal organs. The most common type of mesothelioma is pleural mesothelioma. This kind of tumor starts on the pleural membrane around the lungs.  Peritoneal mesothelioma accounts for…

    Comparing Second-Line Therapies for Recurrent Mesothelioma

    ByAlex Strauss

    University of Pennsylvania researchers have some hopeful news for people with recurrent mesothelioma after chemotherapy: Second-line immunotherapy might increase their odds of survival. Previous studies show that recurrent mesothelioma patients who had immunotherapy lived longer than those on placebo. But doctors were not sure how second-line immunotherapy compared to second-line chemotherapy in these patients. The new study showed a clear survival advantage for those who had immunotherapy.  Coping with Recurrent Mesothelioma Malignant pleural mesothelioma is a rare cancer with a grim prognosis. Most people who receive a mesothelioma diagnosis start treatment with chemotherapy. A combination of Alimta (pemetrexed) and a platinum drug is the most common first-line treatment.  But even the standard-of-care rarely keeps this virulent cancer at bay for…

    Study Asks What is the Best Mesothelioma Surgery?

    ByAlex Strauss

    The best mesothelioma surgery is the one the patient can tolerate with the fewest serious side effects. That’s according to a new study from MD Anderson researchers. Their goal was to help settle the ongoing debate over which type of pleural mesothelioma surgery is most effective.  Both EPP and P/D surgery are major operations. But one causes much more serious side effects than the other. So how do doctors and patients decide on the best mesothelioma surgery for their case? The new research suggests there may not be a definitive answer.  Debate Over the Best Mesothelioma Surgery Pleural mesothelioma is an asbestos-linked cancer of the membrane around the lungs. During EPP (extrapleural pneumonectomy) surgery, doctors remove this membrane, any other…

    Immunohistochemical Staining and Sarcomatoid Mesothelioma: Beyond the Lab

    ByAlex Strauss

    When it comes to understanding individual cases of sarcomatoid mesothelioma, doctors should not rely too heavily on immunohistochemical staining.  That conclusion comes from mesothelioma researchers at MD Anderson Cancer Center in Texas.  The researchers just released a new study focused on this rare mesothelioma subtype. A patient’s subtype has an impact on what kind of treatment could work best for them. Sarcomatoid mesothelioma is usually less responsive to chemotherapy. Immunohistochemical staining is a pathology technique. It is the main way that doctors tell the difference between mesothelioma subtypes.  But the MD Anderson report suggests that not all cases of sarcomatoid mesothelioma are created equal. The researchers say it is important to look beyond the lab findings to understand individual cases….

    Different Mesothelioma Subtypes: Gene Study Could Lead to Targeted Treatments

    ByAlex Strauss

    A group of European pathologists say the different mesothelioma subtypes have significant differences in their pattern of gene expression. Exploiting these differences could help scientists craft more effective mesothelioma treatments.  Asbestos exposure is the primary cause of mesothelioma. But doctors know that genetics play a role, too. Newly-approved immunotherapy drugs target proteins expressed by specific genes. But these drugs work much better in some mesothelioma patients than they do in others.  The new study suggests that differences in the genetic profiles of different mesothelioma subtypes could help explain why.  Immunotherapy Drugs for Mesothelioma Immunotherapy is an up-and-coming treatment approach for mesothelioma and other cancers. It harnesses the power of the person’s immune system to fight cancer.  In people with mesothelioma,…

    Phase 3 Clinical Trial to Test Durvalumab for Mesothelioma

    ByAlex Strauss

    A potential new first-line immunotherapy treatment for mesothelioma is now recruiting patients for a phase 3 clinical trial. The trial will compare the immunotherapy drug durvalumab (IMFINZI) combined with chemotherapy against chemotherapy alone.  Results from the phase 2 trials of this combination released last year were promising. Tests showed that it extended mesothelioma survival by about 8 months with no debilitating side effects.  The randomized phase 3 clinical trial will try to confirm these results in a larger group of people. Mesothelioma Treatment with Durvalumab Durvalumab is an immune checkpoint inhibitor. Immune checkpoint inhibitors deactivate a cancer cell survival mechanism that helps cancer cells evade the immune system. Pleural mesothelioma and other types of cancer use proteins like PD-1 to…

    Mesothelioma Subtypes Often Misclassified by Biopsy

    ByAlex Strauss

    Pleural biopsy is not perfect when it comes to telling the difference between the three mesothelioma subtypes. But misclassification could lead to shorter survival.  That is the conclusion reached by top mesothelioma researchers in Brescia, Italy.  They compared autopsy records from 134 Italian mesothelioma patients. The patients were either shipyard workers or their spouses. The researchers found that the mesothelioma subtypes identified from biopsy tissue were incorrect a large percent of the time. Misclassification matters because it impacts which mesothelioma treatments doctors choose.  The Three Mesothelioma Subtypes Pleural mesothelioma is an aggressive malignancy on the lung lining. It is caused by exposure to asbestos. Mesothelioma cells fall into three mesothelioma subtypes based on certain cellular characteristics. Pleural mesothelioma is notoriously…

  • Opdivo as Second-Line Treatment Option for Mesothelioma: Promising New Data

    ByAlex Strauss

    A new study suggests that the cancer drug Opdivo could be an effective second-line treatment option for people with relapsed mesothelioma. Right now, people whose mesothelioma comes back after treatment do not have an approved second-line treatment option.  The news on Opdivo comes from the first ever placebo-controlled phase 3 trial of patients with relapsed mesothelioma. It shows that the drug significantly improved overall survival for these patients. It also increased the time it took for patients’ cancer to get worse. Details of the CONFIRM Trial The trial of this proposed second-line treatment option for mesothelioma was called CONFIRM. It involved 332 mesothelioma patients from 24 UK cancer centers. The patients already had at least one treatment. Two thirds of…
