Two New Diagnostic Tissue Biomarkers Discovered for Mesothelioma

Identifying Two New Diagnostic Tissue Biomarkers for Mesothelioma

Scientists have now identified two new diagnostic tissue biomarkers for malignant pleural mesothelioma. Doctors identify mesothelioma using diagnostic tissue biomarkers. This is called immunohistochemistry. The use of immunohistochemistry improves the accuracy of mesothelioma diagnosis in clinical practice. Yet, new methods for discovering diagnostic markers are still needed. Following a Reverse Approach in a Rare Case Mesothelioma is usually diagnosed after a person experiencing symptoms goes to a doctor. One thing a doctor may do is perform a tissue biopsy. The doctor will remove a part of the tissue (suspected mesothelioma) for examination. Most tissue biopsies are done with a needle and then examined in a laboratory. The lab will look for specific biomarkers to find out if the tissue contains … Continue reading Two New Diagnostic Tissue Biomarkers Discovered for Mesothelioma »

Detecting Mesothelioma by Smell: A Promising Future

Detecting Mesothelioma by Smell

Early cancer detection can be difficult, but there is a promising history of research on detecting mesothelioma by smell. A new study suggests that a change in a patient’s body odor may be used for early malignant pleural mesothelioma detection. This holds tremendous hope for early treatment. Right now, pleural mesothelioma detection relies heavily on various clinical tests. These tests often include radiography, CT, MRI, ultrasound, and biopsy. All of these technologies and methods are effective. However, several are invasive, expensive, time-consuming, or limited to large hospital settings. In an article in BBA – Reviews on Cancer, researchers explore how body odor can detect malignant pleural mesothelioma. The team says the research on detecting mesothelioma by smell is promising. Nevertheless, … Continue reading Detecting Mesothelioma by Smell: A Promising Future »

Blood Test May Reveal History of Exposure to Asbestos

exposure to asbestos

Small, non-coding bits of RNA in blood serum may offer a way to measure a person’s exposure to asbestos and predict their risk for mesothelioma.  Malignant mesothelioma is just one of several types of cancer linked to exposure to asbestos. But, unless a person knows they have been exposed, doctors might not even think to look for it, even when a patient develops early symptoms.  Researchers at Italy’s University of Ferrara have identified a microRNA in blood serum that can act as a biomarker for asbestos in the body. The discovery could lead to a blood test to identify high-risk people.  Exposure to Asbestos and Malignant Mesothelioma Before asbestos, mesothelioma was virtually unheard of. In fact, when the first asbestos-exposed … Continue reading Blood Test May Reveal History of Exposure to Asbestos »

Biomarkers in Pleural Effusions Can Improve Mesothelioma Diagnosis

biomarkers in pleural effusions

Italian scientists say some newly identified biomarkers in pleural effusions are very good at ruling out mesothelioma in patients who do not have the disease.  Unfortunately, most of these biomarkers are not as good as positively identifying mesothelioma. But their accuracy can be improved by combining several of them.  Pleural effusions are pockets of excess fluid that collect around the lungs of people with certain kinds of cancer and other conditions.  Mesothelioma biomarkers in pleural effusions are proteins and other substances that are mostly found in mesothelioma patients. The new study suggests that using these biomarkers the right way can lead to more accurate diagnoses. The Importance of Biomarkers in Pleural Effusions Pleural mesothelioma is a rare cancer of the … Continue reading Biomarkers in Pleural Effusions Can Improve Mesothelioma Diagnosis »

Breath Test Could Predict Mesothelioma Immunotherapy Response

breath test

New research shows a breath test called an eNose might help doctors determine which mesothelioma patients are most likely to respond to immunotherapy.  Immunotherapy is one of the most promising new approaches to malignant mesothelioma. But not every patient responds.  A new Dutch study suggests that biomarkers in a patient’s exhaled breath may be indicators of immunotherapy response. The eNose breath test can identify those biomarkers quickly and easily. The technology might make it easier to decide on the best mesothelioma treatment.  Immunotherapy for Malignant Mesothelioma Pleural mesothelioma is a rare but deadly cancer of the lung lining. Until last year, chemotherapy with Alimta (pemetrexed) was the only FDA-approved systemic treatment.  In 2020, the FDA approved a combination of immunotherapy … Continue reading Breath Test Could Predict Mesothelioma Immunotherapy Response »

Standard Biomarkers for Pleural Mesothelioma “Not Useful” for Immunotherapy

Biomarkers for pleural mesothelioma

Two of the most important biomarkers for pleural mesothelioma are not much help when it comes to tracking response to immunotherapy. Top mesothelioma researchers at the University of Pennsylvania drew that conclusion based on data from a cohort of 58 patients.  They focused on two primary biomarkers for pleural mesothelioma: SMRP and fibulin-3. Doctors use both of these markers to diagnose and plan treatment for mesothelioma.  The study confirms the correlation between these markers and mesothelioma tumor volume. But the Penn Medicine researchers say these biomarkers of pleural mesothelioma were “not useful” for measuring immunotherapy response. Understanding Biomarkers for Pleural Mesothelioma A biomarker is a substance produced by the body that indicates a biological process or condition. Most mesothelioma biomarkers … Continue reading Standard Biomarkers for Pleural Mesothelioma “Not Useful” for Immunotherapy »

Predicting Mesothelioma Survival with Routine Clinical Tests

predicting mesothelioma survival

UK researchers say predicting mesothelioma survival does not have to be complicated. Their new study shows routine doctor’s office tests may be just as accurate as more complex metrics. The study appears in the new issue of the BMJ Open Respiratory Research journal. It involved 100 patients with malignant mesothelioma over a four-year period.  The team compared treatment outcomes among these patients with their results on basic health tests. More often than not, these tests correctly predicted their prognosis. The researchers say simplifying the process of predicting mesothelioma survival could help doctors and patients make better treatment decisions.  Prognostic Indicators in Asbestos Cancer Malignant pleural mesothelioma is an uncommon but lethal form of membrane cancer. Patients who get it usually … Continue reading Predicting Mesothelioma Survival with Routine Clinical Tests »

Breakthroughs in Mesothelioma in 2020

breakthroughs in mesothelioma

In spite of a global pandemic, there were some major breakthroughs in mesothelioma in 2020 that made the year a hopeful one for people fighting asbestos cancer. Malignant mesothelioma is the most serious illness caused by exposure to asbestos fibers.  Mesothelioma is still not curable. But researchers have made major breakthroughs in mesothelioma diagnosis, prognosis, and treatment this year.  Mesothelioma Treatment Advances Mesothelioma treatment saw the biggest breakthroughs in mesothelioma in 2020. The FDA approved the first systemic treatment for mesothelioma since 2004. That was the year that Alimta (pemetrexed) received approval.  They approved a combination of the immunotherapy drugs Opdivo and Yervoy. Yervoy helps activate and proliferate T-cells. Opdivo helps existing T-cells discover the mesothelioma  tumor. The patients who … Continue reading Breakthroughs in Mesothelioma in 2020 »

New Cancer Blood Test: Could it Find Early Mesothelioma?

new cancer blood test

Researchers in England are testing a new cancer blood test that promises to reveal the presence of hard-to-find cancers like mesothelioma earlier. The country’s National Health Service will offer the test to 165,000 UK residents next year as part of a clinical trial.  “Early detection, particularly for hard to treat conditions like ovarian and pancreatic cancer, has the potential to save many lives,” NHS England’s’ chief executive Simon Stevens told The Guardian newspaper. “This promising blood test could therefore be a gamechanger in cancer care, helping thousands more people to get successful treatment.” If the trial of the new cancer blood test is successful, it could be available to help detect mesothelioma within a few years.  The Challenge of Identifying … Continue reading New Cancer Blood Test: Could it Find Early Mesothelioma? »

Mesothelioma and Metastatic Cancer: New Test Can Reliably Tell the Difference

mesothelioma and metastatic cancer

Italian scientists have come up with what they believe is a nearly foolproof way to tell the difference between mesothelioma and metastatic cancer.  Malignant mesothelioma is a membrane cancer caused by asbestos exposure. Metastatic cancer can start anywhere in the body. It can cause tumors on the pleural membrane that may be mistaken for mesothelioma.  It is important for doctors to distinguish between these two types of malignancies. Mesothelioma and metastatic cancer are often treated differently. The Italian researchers say two biomarkers may make it easier to know which is which.  The Difference Between Mesothelioma and Metastatic Cancer Metastatic cancer or metastatic carcinoma is cancer that has spread to another part of the body from where it started. This usually … Continue reading Mesothelioma and Metastatic Cancer: New Test Can Reliably Tell the Difference »
