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 »

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 »

Accurate Diagnosis of Pleural Mesothelioma with History and Imaging Only

accurate diagnosis of mesothelioma

Medical history and CT imaging may be enough to make an accurate diagnosis of pleural mesothelioma, even without a biopsy. That finding comes from a team of French and Canadian researchers led by Universite Laval in Quebec.  Biopsy is usually considered critical for accurate diagnosis of pleural mesothelioma. But the French and Canadian team says imaging studies may provide enough information to make a diagnosis.  This could be especially good news for people who are not healthy enough to undergo thoracoscopy. Pleural Mesothelioma Diagnostic Procedure: First Steps Pleural mesothelioma is the most common type of mesothelioma. Mesothelioma is an aggressive cancer that grows on the membranes around internal organs.  This cancer is rare and notoriously difficult to diagnose, especially in … Continue reading Accurate Diagnosis of Pleural Mesothelioma with History and Imaging Only »

Pleural Mesothelioma Staging: These Overlooked Lymph Nodes Might Help

pleural mesothelioma staging

An often-ignored set of lymph nodes behind the ribs could help make pleural mesothelioma staging more accurate and valuable.  Staging is the process of determining how advanced a patient’s cancer is. It involves looking at various different factors and assigning a rating between 0 and 4. A higher stage indicates more extensive cancer. A new report suggests that the posterior intercostal lymph nodes behind the ribs play a more important role in pleural mesothelioma staging than previously thought. Mesothelioma patients with cancer in these nodes lived half as long as other mesothelioma patients.  Researchers in Maryland and Pennsylvania say removing and examining these nodes may lead to more accurate staging, more informed treatment decisions, and better outcomes.   How Lymph Nodes … Continue reading Pleural Mesothelioma Staging: These Overlooked Lymph Nodes Might Help »

Minimally Invasive Lymph Node Staging May Prevent Unnecessary Mesothelioma Surgery

lymph node staging for mesothelioma

A minimally invasive procedure for lymph node staging may help some pleural mesothelioma patients avoid the pain and risk of surgery. That is the conclusion of a recent study on endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).  EBUS-TBNA is a minimally invasive method for testing the lymph nodes deep in the chest (mediastinal lymph nodes). If lymph node staging shows evidence of pleural mesothelioma, surgery is less likely to be effective.  Mediastinal Lymph Node Staging and Mesothelioma Pleural mesothelioma is a rare cancer that starts on the membrane around the lungs. It can spread to the lungs and other organs and is usually fatal.  The mediastinal lymph nodes are located in the area between the lungs. When the body is fighting … Continue reading Minimally Invasive Lymph Node Staging May Prevent Unnecessary Mesothelioma Surgery »

Needle Procedure Could Prevent Unneeded Surgery for Malignant Mesothelioma

surgery for malignant mesothelioma

A minimally invasive method for cancer staging could prevent unnecessary surgery for malignant mesothelioma. The method involves putting a needle into the chest behind the breast bone. This area is called the mediastinum. The mediastinum contains critical lymph nodes. The presence or absence of cancer cells in these nodes can help determine whether a patient needs surgery for malignant mesothelioma. Now, a group of Canadian doctors say an ultrasound-guided needle biopsy procedure can provide as much information as more invasive options with less risk and pain. Staging Helps Direct Surgery for Malignant Mesothelioma Most mesothelioma patients receive chemotherapy. If the patient is healthy enough and the cancer has not spread, the patient may also have surgery for malignant mesothelioma. Some … Continue reading Needle Procedure Could Prevent Unneeded Surgery for Malignant Mesothelioma »

New Study Could Lead to a Mesothelioma Breath Test

breath test for mesothelioma

A large new study now underway may eventually make it possible to create a mesothelioma breath test. Cancer Research UK has launched a two-year clinical trial of the Breath Biopsy. The Breath Biopsy is a device that detects molecules exhaled by people with cancer. The Need for Early Mesothelioma Detection Malignant mesothelioma is one of the deadliest types of cancer. Most people who get mesothelioma have been exposed to asbestos. By the time they receive a diagnosis, many mesothelioma patients have advanced disease. Late diagnosis is one of the main reasons people with mesothelioma often die within a year. When mesothelioma cancer is in an advanced stage, it is less likely to respond to treatment. Scientists around the world are … Continue reading New Study Could Lead to a Mesothelioma Breath Test »

Moles Could Point to Mesothelioma Risk

A certain kind of skin lesion may offer a way to identify patients at risk for mesothelioma. Experts at the University of Hawaii, one of the world’s top mesothelioma research centers, say they have identified a type of mole present in people who carry a genetic mutation that may raise their mesothelioma risk. Mesothelioma is a rare but serious cancer of the mesothelial membranes that surround and protect internal organs. Its primary cause is exposure to asbestos. But not all exposed individuals develop mesothelioma. Research conducted by the University of Hawaii’s Dr. Michele Carbone and others found that people with a mutation on the BAP1 gene, a tumor-suppressor known to predispose people to several other types of cancer, also increases their … Continue reading Moles Could Point to Mesothelioma Risk »
