Misdiagnosis of Mesothelioma More Common with Cytology Alone

misdiagnosis of mesothelioma

A new set of case reports illustrates how easily misdiagnosis of mesothelioma can happen when the diagnosis is based on cytology alone.  Cytology tests look at the cells in body fluids. For peritoneal mesothelioma patients, this is often the fluid that collects in their abdomen called ascites.  But doctors from India’s Dayanand Medical College and Hospital say using ascites samples alone to diagnose mesothelioma is a risky practice. Misdiagnosis of mesothelioma may delay proper treatment and negatively impact survival. The Difficulty of Diagnosing Peritoneal Mesothelioma Malignant mesothelioma only impacts about 2,500 people in the US every year. It is most common among people who have lived or worked around asbestos. Peritoneal mesothelioma is even rarer. About a fifth of patients … Continue reading Misdiagnosis of Mesothelioma More Common with Cytology Alone »

Immunohistochemical Staining and Sarcomatoid Mesothelioma: Beyond the Lab

immunohistochemical staining

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. … Continue reading Immunohistochemical Staining and Sarcomatoid Mesothelioma: Beyond the Lab »

Predicting the Risk of Death from Mesothelioma

risk of death from mesothelioma

New research suggests that the risk of death from mesothelioma does not always hinge on disease type or overall health. Researchers in Brazil and at Mayo Clinic have identified some subtle mesothelioma risk factors that only pathologists can see. These factors go beyond the characteristics of the mesothelioma cells themselves. The study shows the environment around the tumor, the number and type of immune system cells at the tumor site, and even how many cells are in the tumor can all impact the risk of death from mesothelioma.  Understanding the Risk Factors for Mesothelioma Asbestos exposure causes most cases of mesothelioma. But not everyone who encounters asbestos gets cancer. Genes and certain lifestyle factors may influence whether an exposed person … Continue reading Predicting the Risk of Death from Mesothelioma »
