Mesothelioma Lawyers Information
Mesothelioma Lawyers : The fluid and the tissue from the pleural biopsy will be sent to a pathologist and/or cytologist who will look under the microscope at the cells and determine whether mesothelioma is present. In the past, a diagnosis of mesothelioma from fluid alone was possible only a third of the time because of the difficulty of distinguishing between reactive or noncancerous cells and tumor cells. By staining the fluid with a special substance, pathologists can now make a diagnosis more easily. Your doctor will refer to these stains as “immunos,” short for immunohistochemistry. You should make sure that any material used in the biopsy has been studied using these immuno stains. A chest x-ray is always performed after these procedures to make sure there were no complications from the biopsies, such as an accumulation of air in the chest (pneumothorax). The chest x-ray is also very important to see whether the majority of the fluid has been removed and if the lung is now able to expand with air and fill the chest cavity as it normally should.

More-invasive testing may be needed if the initial results of the semi-invasive tests do not provide adequate information or if the CT scan indicates that it would be difficult to do the semi-invasive tests. The latter situation would occur if the fluid is not free flowing but is hidden in pockets that are difficult to reach. In such cases, it is better to inspect the chest directly to find out where to do the biopsy. A thoracoscopy (the use of a lighted scope, with or without a camera, to look into the chest) is performed in patients who are at risk for mesothelioma and who develop a large fluid accumulation, with or without associated solid tumor masses in the chest. In patients who are at risk for mesothelioma but whose thoracentesis does not reveal cancer cells, or who experience a recurrence of fluid after the initial thoracentesis is performed, a thoracoscopy should probably be performed. This procedure involves using a special lighted instrument called a thoracoscope to look inside the chest cavity. The scope is placed into the chest between two ribs after a small (1-inch) cut is made through the chest wall. If the doctor finds any tissue that looks abnormal, he or she will cut out a piece, or biopsy a piece, of it to have it looked at under the microscope. This tissue will then be examined for cancer cells. Mesothelioma Lawyers

Lastly, if the radiologic tests indicate that there is more solid tumor than fluid, or if there is no longer a space where fluid can accumulate because of previous attempts to control the fluid, an “open” biopsy may be indicated. The incision does not have to be large if the pleura is thickened, but the procedure should be performed by a thoracic surgeon who understands the principles of mesothelioma treatment. This surgeon will usually suggest a 3- or 4-inch incision on the side of the chest, overlying an area of pleura that is thickened. The surgeon may or may not remove a small piece of rib at this site to allow a direct view of the thickened pleura. Many times, a good-sized piece of pleura (1 to 1 1/2 inches in diameter) can be removed at this site. Getting a quick freeze of the tissue in the operating room, with the pathologist looking at the biopsy, will ensure that there’s enough tissue to perform all the required testing and to make a diagnosis. Surgeons performing these biopsies should pick the right place for the biopsy, and the cut (incision) for this biopsy should be in line with the longer incision that would be used later if the patient is a surgical candidate. That way, this shorter incision can be removed.
