Asbestos and Immunohistochemical Diagnosis of Mesothelioma

One interesting study is called, “The role of immunohistochemistry in the diagnosis of malignant mesothelioma.” By Moran CA, Wick MR, Suster S. Department of Pathology, The University of Alabama at Birmingham, 35294, USA. Semin Diagn Pathol. 2000 Aug;17(3):178-83.  Here is an excerpt: “Abstract – The immunohistochemical diagnosis of mesothelioma is perhaps one of the most perplexing and controversial issues in surgical pathology. A tumor that in essence is extremely rare has managed to captivate the attention not only of pulmonologists and thoracic surgeons but also of pathologists. Throughout its history, mesothelioma has emerged as one of the tumors that has evaded definitive characterization; hence, the numerous attempts at trying to establish not only histological criteria but also histochemical, immunohistochemical, and ultrastructural guidelines for its diagnosis.

Perhaps as we enter an era of more sophisticated technology, molecular biology will have an opportunity to make inroads into the diagnosis and characterization of this peculiar neoplasm. Despite the many difficulties involved in the diagnosis of malignant mesothelioma, we have recently gained significant knowledge of this entity in many respects, several decades after its description. From a morphological point of view, several variations of the histological appearances that these tumors may exhibit have been described. Traditional histochemistry and electron microscopy continue to play an important role in the evaluation of these neoplasms, with ultrastructural analysis in particular representing the most reliable technique for making this diagnosis in equivocal cases. However, because of its speed, cost-effectiveness, and general availability, immunohistochemistry has emerged as the most commonly used procedure for the diagnosis of mesotheliomas. We herein present a review of the current status of immunohistochemical evaluation of malignant lesions that are suspected of having a mesothelial lineage.”

Lung Cancer when Associated with Asbestosis and Mesothelioma is an Occupational Disease

The assertion that asbestosis must be present in order to attribute a lung cancer to asbestos exposure does not meet accepted standards for establishing causation.  One interesting study is called, “Historical perspectives in occupational medicine. Changing attitudes and opinions regarding asbestos and cancer 1934–1965″ by Philip E. Enterline PhD – American Journal of Industrial Medicine Volume 20, Issue 5, pages 685–700, 1991.  Here is an excerpt: “Abstract – Literature published in the years 1934–1965 was reviewed to determine attitudes and opinions of scientists as to whether asbestos is a cause of cancer. In Germany, the issue was decided in 1943 when the government decreed that lung cancer, when associated with asbestosis (of any degree), was an occupational disease. In the United States, however, there was no consensus on the issue until 1964.

Opinions of scientists over a 22 year period are shown and the contributions of various cultural, social, economic and political factors to these opinions are discussed. A lack of experimental and epidemiological evidence played a major role in delaying a consensus. Other important factors included a rejection of science conducted outside of the U.S. during this period, particularly a rejection of German scientific thought during and after WWII, and a rejection of clinical evidence in favor of epidemiological investigations. Individual writers rarely changed their minds on the subject of asbestos as a cause of cancer.”

Asbestos Removal A Must

Asbestos is known to be a material that is used in building houses and making protective clothing. It is a mineral that doesn’t burn easily and though it is very durable, asbestos is known to be very dangerous to the health because of its carcinogen content. There were studies that have sprouted about the dangers of this mineral that asbestos removal is already being implemented by most countries.

Cancer and destruction of the lungs is the number one illness associated with asbestos fiber. For the workers, it is very hazardous for them to inhale this chemical. They are the people who are prone to catch this illness since they get to inhale this material day in and day out while constructions are going on. With it as a remedy to avoid this kind of illnesses is a must. Of course we do not disregard that asbestos is really a good kind of material and it is very essential in the field of construction, and not only that, it is also affordable and does not cost an arm and a leg compared to other materials. However; which may be more important? Risking too many lives for just a material or looking for an alternative material which is not harmful for the people to use?

Aside from cancer and breathing problems, without the asbestos removal, illnesses such as asbestosis, warts and pleural plaques. Asbestosis is a lung disease that doesn’t have any treatment. Cough and shortness of breath are often the symptoms of this and it becomes incurable causing oxygen shortage over time and death. Warts are growth of callous in the skin is one of the problems associated from inhaling asbestos. Phlegm becomes visible sign too. This phlegm would cause much problems to the lungs and eventually cause death to may. That is why it is sought after by many countries. They have even branded this material as a hazardous waste that needs to be removed.
