Liquid Biopsy for Early Stage Mesothelioma Diagnosis

liquid biopsy

Canadian researchers are exploring a liquid biopsy test that could lead to early diagnosis of malignant mesothelioma. The test is based on mesothelial precursor cells (MPC). The researchers say these cells – in combination with mesothelin and some kinds of stem cells – “could be implicated” in the development of mesothelioma.  A liquid biopsy detects cells in blood instead of tissue. The University of Toronto scientists think MPC in blood may be a new mesothelioma biomarker. If it proves to be true, this kind of biopsy might be able to identify mesothelioma patients even before they have symptoms. How Liquid Biopsy Works Patients with suspected mesothelioma may have many tests. Imaging scans and blood tests can help tell if a … Continue reading Liquid Biopsy for Early Stage Mesothelioma Diagnosis »

The Peritoneal Cancer Index in Mesothelioma Prognosis

peritoneal cancer index

The peritoneal cancer index is a valuable prognostic tool and should be considered in mesothelioma treatment planning. That is the word from a group of Finnish cancer researchers. They analyzed twelve years of data on peritoneal mesothelioma in their country. Mesothelioma patients with a higher peritoneal cancer index had a worse prognosis than those with a lower PCI. The group says cancer doctors ought to be including the PCI in their decision-making for people with peritoneal mesothelioma. What is the Peritoneal Cancer Index? Peritoneal mesothelioma makes up about a fifth of all mesothelioma cases. It grows on the peritoneum, a membrane that surrounds the abdominal organs. As cancer spreads, tumors can show up in other areas inside the peritoneal cavity.  … Continue reading The Peritoneal Cancer Index in Mesothelioma Prognosis »

The Best Biomarkers for Mesothelioma Diagnosis, Prognosis, & Monitoring

Best Biomarkers for Mesothelioma

What are the best biomarkers for mesothelioma? The answer is still Soluble Mesothelin-Related Proteins (SMRPs). That is the conclusion of a major review of medical literature by some of the world’s top mesothelioma experts. Dr. Harvey Pass of New York University’s Langone Medical Center and Dr. Michele Carbone of the University of Hawaii are among the authors on the new report.  They analyzed 20 years of research on the best biomarkers for mesothelioma. Several were valuable for mesothelioma prognosis. But SMRPs once again came out the winner for mesothelioma prognosis, diagnosis, and treatment monitoring.  How Do Biomarkers Work? A biomarker is any substance produced by the body that can act as a biological signpost. Proteins usually make the best biomarkers … Continue reading The Best Biomarkers for Mesothelioma Diagnosis, Prognosis, & Monitoring »

BAP1 Expression Not an Independent Factor in Mesothelioma Prognosis

BAP1 Expression and Mesothelioma Prognosis

A new report says the prognostic role of BAP1 expression in mesothelioma is not as cut-and-dried as some studies suggest. Italian researchers analyzed the cases of 698 patients with pleural mesothelioma. The group included 60 of their own patients and another 638 from other studies. Their analysis suggests that mesothelioma prognosis has more to do with subtype than with genetic BAP1 expression. They caution doctors not to put too much stock in a patient’s BAP1 status without also considering other factors. Genetic Alterations and Mesothelioma Survival Asbestos exposure is the primary cause of mesothelioma. But not everyone who is exposed to asbestos gets cancer. This may have to do with their genetic makeup. Certain genetic alterations may make a person … Continue reading BAP1 Expression Not an Independent Factor in Mesothelioma Prognosis »

Artificial Intelligence in Mesothelioma Diagnosis, Prognosis, and Treatment Planning

Artificial Intelligence

Two newly-published studies highlight some of the ways that artificial intelligence may help with the diagnosis and treatment of malignant mesothelioma.  The first study focuses on machine learning algorithms for mesothelioma diagnosis. Researchers used data from Turkey, which has a high rate of mesothelioma among families.  A separate study from New York’s Mount Sinai Medical Center demonstrates the role that artificial intelligence can play in planning mesothelioma radiotherapy. Both studies suggest that machine learning may be a valuable tool to help doctors tackle asbestos cancer.  How Does Machine Learning Work? Artificial intelligence refers to intelligence generated by a computer. Like people, computers have to “learn” before they can provide intelligent answers to medical questions.  In both of the new studies, … Continue reading Artificial Intelligence in Mesothelioma Diagnosis, Prognosis, and Treatment Planning »

Breast Cancer and Mesothelioma: Case Study Illustrates Diagnostic Challenge

breast cancer and mesothelioma

A newly published Croatian case illustrates how challenging it can sometimes be to distinguish between breast cancer and mesothelioma. The case involves a 61-year-old woman with what appeared to be breast cancer. Further study revealed that what the woman actually had was pleural mesothelioma. The mesothelioma had spread to her breast.  Breast cancer and mesothelioma cells look similar under the microscope. But they are very different. The authors of the new report caution doctors against the “pitfall” of mistaking one for the other.  Breast Metastasis is Rare Pleural mesothelioma occurs on the membrane that surrounds the lungs. It is rare for mesothelioma to spread to the breast. The most common place for mesothelioma cells to spread is the lungs.  Women … Continue reading Breast Cancer and Mesothelioma: Case Study Illustrates Diagnostic Challenge »

PD-L1 Expression and Mesothelioma Prognosis

PD-L1 expression and mesothelioma prognosis

The largest study yet on PD-L1 expression and mesothelioma prognosis shows that patients with more of this protein in their cells have poorer odds of survival. Programmed death ligand 1 (PD-L1) helps cancer cells evade immune system attack.  Other studies have suggested a link between PD-L1 expression and mesothelioma prognosis. But the new meta-analysis performed by two Chinese researchers appears to confirm it with an even bigger data set.  Understanding Mesothelioma Prognosis Malignant mesothelioma is an uncommon cancer that typically carries a poor prognosis. Many people diagnosed with mesothelioma lose their lives to the illness within a year.  But there are also many exceptions. Some mesothelioma survivors live for decades after a mesothelioma diagnosis. Australian Paul Kraus is an example. … Continue reading PD-L1 Expression and Mesothelioma Prognosis »

The Importance of Subtype in PET Scanning for Mesothelioma Prognosis

PET scanning for mesothelioma

A new study of PET scanning for mesothelioma prognosis shows how much radioactive tracer a tumor absorbs can predict survival. This is especially true in people with the epithelioid mesothelioma subtype.  The study comes from the Sungkyunkwan University School of Medicine in Seoul, South Korea. Researchers studied the medical records of dozens of mesothelioma patients diagnosed between 2009 and 2018. They found that SUVmax, a key factor in PET scanning for mesothelioma, is directly related to mesothelioma survival.  How PET Scanning Works Mesothelioma diagnosis is challenging. Pleural mesothelioma grows quickly on the membrane around the lungs. It is one of the rarest and deadliest cancers. Positron emission tomography (PET) combined with computed tomography (CT) can help with diagnosis.  During a … Continue reading The Importance of Subtype in PET Scanning for Mesothelioma Prognosis »

It May Be Possible to Predict Recurrence of Mesothelioma with Help from AI

predict recurrence of mesothelioma

A newly-published report suggests that artificial intelligence (AI) might help pathologists predict recurrence of mesothelioma. The report focuses on technology developed by the RIKEN Center for Advanced Intelligence Project (AIP) in Japan. The Center claims the computer program taught itself to recognize key features in images of cancer.  Some of the features were ones that even pathologists did not know about. The findings suggest that AI and pathologists could predict recurrence of mesothelioma better than pathologists alone.  How AI Might Predict Recurrence of Mesothelioma  A computer program usually has to be “taught” to perform a certain task. But this limits how far the learning can go. Instead of “teaching” it about cancer, researchers let the RIKEN technology learn on its … Continue reading It May Be Possible to Predict Recurrence of Mesothelioma with Help from AI »

Minimally Invasive Mesothelioma Diagnosis from Lung Fluid

minimally invasive mesothelioma diagnosis

Minimally invasive mesothelioma diagnosis with lung fluid may be just as effective as a tissue biopsy. That’s according to Australian mesothelioma researchers. Australia was once one of the biggest producers of asbestos and now has some of the highest mesothelioma rates in the world. It is also home to high-level mesothelioma research. In the latest study, scientists ran a meta-analysis comparing surgical biopsy with a minimally invasive mesothelioma diagnosis tool called cytology. Their conclusion is that surgery may not always be necessary to diagnose malignant mesothelioma. Tissue Versus Lung Fluid Malignant mesothelioma is a fatal cancer caused by exposure to asbestos. It is challenging to diagnose because the symptoms are often vague and similar to other less serious conditions. Doctors … Continue reading Minimally Invasive Mesothelioma Diagnosis from Lung Fluid »
