EARLY DIAGNOSIS OF MESOTHELIOMA CANCER
Today the only proven cause of mesothelioma is exposure to asbestos. Diagnosis mesothelioma is often difficult, because mesothelioma symptoms may not appear until 30 to 50 years after exposure to asbestos and symptoms are similar to those of a number of other conditions. The importance of early diagnosis for mesothelioma cancer patients cannot be overemphasized. here you can learn as about traditional methods as about new methods of mesothelioma diagnosis.
MESOMARK BLOOD TEST In January 2007, the Food and Drug Administration (FDA) approved the MESOMARK assay to help monitor response to treatment in malignant mesothelioma patients. The MESOMARK test signifies the beginning of a new era in monitoring mesothelioma malignancies," said Dr. W. Jeffrey Allard, vice president and chief scientific officer of Fujirebio Diagnostics. "As the first in-vitro test for patients with this aggressive disease, it will enable doctors to more accurately detect recurrence and monitor treatment of patients." The MESOMARK Assay test kit was developed to measure levels of a biomarker, mesothelin, in serumBiomarkers are substances found in higher-than-normal concentrations in the blood, urine or body tissues of patients with certain types of cancers. The test may be used to monitor patients confirmed as having mesothelioma, for recurrence in patients following surgery, or for measuring response to therapies. "Current diagnostic tests are less than ideal for quantification of changes in tumor volume, which is key to managing the disease," continued Allard. "As the MESOMARK results correlate with tumor volume*, it provides a much needed tool for monitoring patient status. It is our plan to collect additional data in the future to support the use of the test to detect mesothelioma." MESOMARK test are now making it possible - with a simple blood test -to monitor response to treatment and to detect recurrence following treatment. This provides an important head start to patients racing against this aggressive cancer. "The Meso Foundation is the national research funding, patient support and advocacy organization dedicated to eradicating mesothelioma as a life-threatening disease. LDCT Evaluated for Early Detection of Lung Cancer and MesotheliomaAccording to a recent and promising study in The Oncologist, researchers found that LDCT (Low Dose Computed Tomography) may be helpful in detecting pleural abnormalities including the early diagnosis of malignant pleural cancer and mesothelioma. Researchers evaluated LDCT, i.e., spiral or helical computed tomography, screening of those exposed to asbestos. LDCT proved more effective at early detection of lung cancer than a chest radiograph (x–ray).The objective of the study was to create a nonrandomized trial to evaluate the feasibility of baseline and annual repeat screening using LDCT for the early diagnosis of lung cancer and malignant pleural mesothelioma. Researchers concluded that LDCT was 19 times more likely to detect nodules than the x–ray. Learn more about the results of LDCT study Traditional methods of diagnosis mesothelioma
of fluid is present, abnormal cells may be detected by cytology if this fluid is aspirated with a syringe. For pleural fluid this is done by a pleural tap or chest drain, in ascites with an paracentesis or ascitic drain and in a pericardial effusion with pericardiocentesis. While absence of malignant cells on cytology does not completely exclude mesothelioma, it makes it much more unlikely, especially if an alternative diagnosis can be made (e.g. tuberculosis, heart failure). If cytology is positive or a plaque is regarded as suspicious, a biopsy is needed to confirm a diagnosis of mesothelioma. In a biopsy, a surgeon or a medical oncologist (a doctor who specializes in diagnosing and treating cancer) removes a sample of tissue for examination under a microscope by a pathologist. A biopsy may be done in different ways, depending on where the abnormal area is located. If the cancer is in the chest, the doctor may perform a thoracoscopy. In this procedure, the doctor makes a small cut through the chest wall and puts a thin, lighted tube called a thoracoscope into the chest between two ribs. Thoracoscopy allows the doctor to look inside the chest and obtain tissue samples. If the cancer is in the abdomen, the doctor may perform a peritoneoscopy. To obtain tissue for examination, the doctor makes a small opening in the abdomen and inserts a special instrument called a peritoneoscope into the abdominal cavity. If these procedures do not yield enough tissue, more extensive diagnostic surgery may be necessary. If the diagnosis is mesothelioma, the doctor will want to learn the stage (or extent) of the disease. Staging involves more tests in a careful attempt to find out whether the cancer has spread and, if so, to which parts of the body. Knowing the stage of the disease helps the doctor plan treatment. Mesothelioma is described as localized if the cancer is found only on the membrane surface where it originated. It is classified as advanced if it has spread beyond the original membrane surface to other parts of the body, such as the lymph nodes, lungs, chest wall, or abdominal organs. about misdiagnosis pericardial mesothelioma Steve McQueen's Mesothelioma Diagnosis Many are aware that famous movie actor, Steve McQueen, died of cancer. But few are aware he actually had a mesothelioma diagnosis. As most are also not aware, Steve McQueen worked in a shipyard as a young man where he was likely exposed to asbestos.
