The deadly cancer of epithelial mesothelioma

February 16, 2012 – 3:31 am

Epithelial mesothelioma is a rare and deadly form of cancer affects the membrane lining the chest cavity, heart, lungs and abdominal cavity. There are three forms of epithelial mesothelioma: the most common, pleural mesothelioma; the second most common, peritoneal mesothelioma (accounting for only a quarter of the cases) and the rarest form, pericardial mesothelioma.

The vast majority of epithelial mesothelioma cases are the result of asbestos exposure. Indeed, one of the most frustrating aspects of this type of cancer is that patients who develop it were generally exposed 15 to 40 years before hand, which often makes the time and place the disease was contracted difficult to determine.

The early symptoms of epithelial mesothelioma are subtle and somewhat general. Shortness of breath and chest pain are the most common early symptoms. It is because these symptoms are so generic that epithelial mesothelioma is rarely detected early on. Usually when its discovered it is already in an advanced stage and treatment options, particularly localized options such as surgery, are somewhat limited.

If the cancer is in a less advanced stage, aggressive surgery treatments can be sought. Aggressive treatments are treatments aimed at curing the mesothelioma or at least increasing the patients longevity. In some cases an extrapleural pneumonectomy can be performed to try to stop the spread of the mesothelioma.

However this operation is risky and many medical centers will not perform it because of its high mortality rate. Additionally this procedure involves removing an entire lung, as well as extensive epithelial tissue, thereby reducing the patients breathing capacity in half. Even when it is successful it rarely eliminates the mesothelioma, but rather only slows its progress.

Palliative surgery (surgery only aimed at alleviating symptoms) is an option at any stage of the disease. Usually this comes in the form of a “fine needle aspiration” or pleural tap. A pleural tap involves injecting a long needle into the chest or abdomen cavity and draining the pleural space of fluid build up. This procedure may greatly reduces symptoms associated with mesothelioma.

Radiation therapy and chemotherapy are other options. Both are systemic treatments and have the draw back of affecting surrounding tissues as well as cancerous tissues. Radiation therapy is often used in combination with surgery treatments as a way of attempting to remove cancerous growth that could not be removed through surgery. Chemotherapy still has not proved very effective against epithelial mesothelioma but doctors and researcher continue to experiment with new techniques.

Asbestos exposure leads to the types of mesothelioma

February 13, 2012 – 7:17 am

Mesothelioma is a rare form of cancer where malignant cells are found in the protective sacs that cover the body’s internal organs. This protective sac is known as the mesothelium. This fatal disease is caused by exposure to asbestos.

There are four basic types of mesothelioma. Pleural Mesothelioma is the most common type. Here, the cancer develops in the lining of the lungs causing the build up of fluid. This fluid puts pressure on the lungs, making it difficult and painful to breath. Pleural mesothelioma can be difficult to diagnose because the symptoms can take several years to develop, and are easily mistaken for other diseases like pneumonia.Peritoneal Mesothelioma is less common, and develops in the abdomen. As the cancerous cells begin to thicken, fluid builds up and tumors start to form. This often results in stomach pain, nausea and changes in bowel habits.

Percardial Mesothelioma is one of the rarest forms of mesothelioma, accounting for less than 6% of all cases. Percardial tumors tend to cover most of the heart. People diagnosed with pericardial mesothelioma are typically not good candidates for surgical procedures, and instead rely on palliative treatments to help relieve pain and improve quality of life.

Testicular Mesothelioma is the rarest form, accounting for less than 100 cases reported worldwide. Here, the cancer develops in the membraneous lining surrounding the testicle.

Malignant pleural mesothelioma-The conventional options treatment rate

February 13, 2012 – 6:53 am

Malignant pleural mesothelioma is a malignancy located in the membrane that covers the lungs. Pleural mesothelioma is the most common form of mesothelioma; about 80-90% of the cases begin in the pleural.

In general, the symptoms of malignant pleural mesothelioma which may send a patient to the doctor are:

A persistent cough
Difficulty swallowing
Shortness of breath or difficulty breathing
Sleep disturbances
Pain, particularly in the chest, abdomen or lower back, which doesn’t respond to over-the-counter pain medication
Loss of appetite and weight loss
Often, when the patient is examined, fluid accumulation is found in the chest cavity; it can usually be seen on a chest x-ray or heard during the physical examination.

How easy it is to treat pleural mesothelioma depends on the staging of the tumor. The earlier it is diagnosed, the more likely it is that surgical treatment will lengthen life expectancy, survival rate. A combination of surgery, chemotherapy and radiation, known as trimodality therapy has shown a survival rate of 45% at 2 years and 22% at 5 years.

Pleural mesothelioma is sometimes diagnosed by accident, before there are any symptoms, often when a routine x-ray is done. As the tumor spreads over the pleura, the pleura thickens and becomes less flexible and more restrictive. The lungs become less functional and breathing is increasingly difficult.

Malignant pleural mesothelioma may resemble other lung-related cancers; historically, it has required further examination of the tissue sample by staining and viewing with an electron microscrope. Recently, however, a blood test has been developed that can point to mesothelioma pretty reliably.Âł This greatly simplifies the diagnostic process, and because the test can help diagnose mesothelioma long before typical symptoms show up, treatment can begin much earlier, when the prognosis is much better.

The rank of pleural mesothelioma has been to the top

February 10, 2012 – 7:21 am

Pleural mesothelioma is ranked as the most commonly occurring form of mesothelioma. It develops along the pleura, which is commonly referred to as the lining that protects and supports the lung. The membrane serves to line a number of cavities within the body. Although pleura mesothelioma affects the functions of the lungs, it is not classified as lung cancer. It is not always easy for doctors to come up with an accurate diagnosis of pleural mesothelioma because of some of the symptoms not being specified or their similarity to the symptoms of other conditions.

People who have been exposed to asbestos need to inform their doctors and let them know if they experience certain symptoms or suspect that they may have pleural mesothelioma. This makes it easier for the physician to identify the present symptoms. Although infected with pleural mesothelioma can be discouraging, no one should ever take it as a death sentence. There are a number of treatment options that are available and can be used to effectively deal with the condition. Pleural mesothelioma is mainly caused by extensive exposure to asbestos, especially by people whose occupations expose them to the toxic substance.

The toxic fibers of asbestos are very small and easily passed through the air. When they are present in the air, they can easily be inhaled owing to their small size that enables them to penetrate the lungs and eventually become present in the pleura. The toxic fibers have the adverse effect of compromising the body’s ability to defend itself. It is believed that the chemical composition of the toxic fibers contribute to the abnormal division of the mesothelial cells. Over time it has become evident that there is a direct link between asbestos fibers and pleural mesothelioma.

The serious effects of asbestos on one’s overall health clearly show how toxic and dangerous the substance is and it results in the highest rate of occupational cancers. People who are aware of their exposure to asbestos need to know that they are at a high risk of developing the disease and should seek timely medical attention. Anyone who suspects that they may have pleural mesothelioma probably has a history of exposure to asbestos. Since the symptoms of the disease are not limited to the disease, they can easily be attributed to other medical conditions. However, people who have previously been exposed to asbestos should be committed to frequent medical examinations that can help to detect the presence of the disease.

Bring the peritoneal mesothelioma to the normal life

February 9, 2012 – 6:03 am

Pleural and peritoneal mesothelioma are fatal forms of cancer resulting from asbestos exposure. There are a myriad of studies that examine the issue of causation, but one in particular that deserves credit is called, “Features of asbestos-exposed and unexposed mesothelioma” by A Hirsch, MD, P. Brochard, MD, H. De Cremoux, MD, Dr. L. Erkan, MD, P. Sebastien, PhD, L. Di Menza, MD, and J. Bignon, MD – Clinique de Pathologie Respiratoire et Environnement, INSERM U 139 et ERA CNRS No. 845, Centre Hospitalier Intercommunal, 40 Ave de Verdun, 94010 CrĂ©teil cedex, France – American Journal of Industrial Medicine – Volume 3 Issue 4, Pages 413 – 422. Here is an excerpt: “Abstract – Thirty-six histologically confirmed cases of pleural and peritoneal mesothelioma have been observed in a chest unit over a period of 53 months.

The past asbestos exposure was assessed by a standardized questionnaire in all cases and the asbestos lung burden was determined by means of mineralogical analysis of lung-related biological specimens (sputum, bronchoalveolar lavage fluid, lung tissues) in 28 cases. The results of these two methods were found in good agreement. Past asbestos exposure has been definitely implicated in 17 cases and definitely eliminated in 10 cases. The results were nonconclusive in other cases. The group with definite past asbestos exposure was different from the nonasbestos-exposed group by clinical, biological, pathological, and prognosis features that were analyzed. In cases without past asbestos exposure there were no other possible causative agents. Younger age and similar incidence in men and women suggest an environmental or natural disease.”

Another interesting article that explores chromosome abnormalities is called, “Chromosomal abnormalities and their correlations with asbestos exposure and survival in patients with mesothelioma.” By M. Tiainen, L. Tammilehto, J. Rautonen, T. Tuomi, K. Mattson, and S. Knuutila – Department of Medical Genetics, University of Helsinki, Finland – Br J Cancer. 1989 October; 60(4): 618–626. Here is an excerpt: “Cytogenetic findings of our 30 previously reported and eight new patients with malignant pleural mesothelioma were summarised and correlated with asbestos fibre burden in lung tissue and survival. Successful cytogenetic analyses were performed on cells obtained from the tumours and/or pleural effusions of 34 of the 38 patients. Clonal chromosomal abnormalities were detected in 25 patients, 19 of them studied before treatment. Nine patients, seven of them studied before treatment, had normal karyotypes and/or non-clonal chromosomal abnormalities.

Malignant mesothelioma caused by the asbestos exposure

February 8, 2012 – 7:07 am

Malignant mesothelioma is a cancer, where the cells in the linings of chest or abdomen, thought it is rare type of cancer it is caused by working where you are exposed to asbestos particles in air.

The Malignant mesothelioma is affecting of the layer of specialized cells called mesotheliali cells that line the inside of chest, abdomen and space around heart. These cells also form a cover to the outer surface of most of internal organs i.e. this lining of cells is called mesothelium. This lining of mesothelium protects organs by making a special lubricating fluid that allows organs to move around. For example to explain the importance of fluid, it makes lungs to move inside the chest easier during breathing. The mesotheliums have different names in different parts of human body:
• In chest: pleura.
• In abdomen: peritoneum.
• In the space around the heart: pericardium.
Tumors of the mesothelium can be non- cancerous and even cancerous that is malignant.

Malignant mesothelioma is cancer caused mainly of work because Mesothelioma is caused by asbestos exposure. Asbestos, which was regarded as a wonder mineral, is popular as it has lightweight though it is also has tough characteristics and along with its heat-resistant properties it makes to be miracle mineral for loads of industries. Also this is a naturally occurring mineral, which was used in many commercial and consumer products, and in many industries like usage in construction materials such as cement, roofing shingles and insulation, using to consumer and industrial applications such as hair dryers, automobile brake pads and pipe insulation.

It was observed that most people with malignant mesothelioma worked on jobs where they breathed asbestos. Though there have been also cases where others were exposed to asbestos in a household environment, often without knowing its harmful effect, which now has caused them malignant mesothelioma.

The impact of pleural mesothelioma cancer

February 7, 2012 – 6:07 am

Pleural mesothelioma cancer generally emerges as multiple tumor masses having an effect on the parietal surface and visceral surface of the pleura. In general, the parietal surface has greater involvement than the visceral. There is a fairly higher prevalence of mesothelioma in the right lung, seemingly because of the fact that the right lung is larger and has a greater amount of pleural surface area. In addition, the lower lungs usually demonstrate more tumor masses than the upper lung.

Pleural mesothelioma lung cancer assaults the cells that make up the pleura or lining around the outside of the lungs and also inside of the ribs. Its simply known cause in the U.S. is previous exposure to asbestos fibers, encompassing chrysotile, crocidolite or amosite. This exposure is probable to have occurred twenty or more years before the disease becomes obvious, given that it takes several years for the disease to “incubate.” It is the most common kind of mesothelioma, accounting for roughly 75% of all cases.

pleural mesothelioma cancer

Mesothelioma is not technically categorized as lung cancer. It is cancer of the lining of the lungs, which in its late stages might cause enlargement of a tumor or tumors in the lung. In general, pleural mesothelioma shows diffuse small tumors which lead to the thickening of the pleural membrane and the growth of exudative pleural effusion.

However pleural effusion with lung cancer is a standard coupling of symptom and diagnosis too. Pleural effusion could be symptomatic of pneumonia and other viral infections as well, which is one basis why mesothelioma is frequently not diagnosed until its late stages.

It’s not always uncomplicated to diagnosis pleural mesothelioma by analyzing its symptoms. All too frequently, the symptoms of the disease might bear a resemblance to those of other more common diseases, encompassing something as simple as the flu, pneumonia, a cold, laryngitis, or whopping cough.

We should strong enough to against primary peritoneal mesothelioma

February 6, 2012 – 6:43 am

Background: Primary peritoneal mesothelioma is a rare disease with an unpredictable clinical course. This has led to a variety of treatment options, ranging from minimal debulking, debulking with adjuvant intraperitoneal (i.p.) chemotherapy to aggressive debulking with peritonectomy with hyperthermic intra-operative i.p. perfusion. It is unclear whether outcome is dependent on treatment, patient selection or tumor biology.

Methods: A retrospective review of all patients with primary peritoneal mesothelioma treated at a single institution between 1/1/82-1/1/02 was performed. Patient, tumor and treatment variables were reviewed.

Results: Thirty-seven pts. with primary peritoneal mesothelioma were identified. Patients with pleural mesothelioma with peritoneal extension were excluded. Median follow-up was 49 months (range 3-97mos.) There were 15 male and 22 female pts. with a median age of 56 years. All pts. were explored with the pre-operative goal of maximal cytoreduction with minimal sacrifice of adjacent organs. Total peritonectomy was not performed. The adequacy of debulking was grouped into 5 categories ranging from 0-25% debulked (12 pts.), 26-50% (5 pts.), 51%-75% (1 pt.), 76%-99% (13 pts.) or complete (6 pts.) The overall complication rate was 30% with 3 post-operative deaths. Thirty pts. (81%) were treated with adjuvant chemotherapy: 18 pts. received only i.p. chemotherapy, 7 received both i.p. and i.v. chemotherapy and 5 received i.v. chemotherapy only (7 unknown). The most common i.p. regimen was combined cisplatin/mitomycin C (17 pts.) (Cancer Res Clin Oncol 1992, 118:547-50). The median overall survival was 58 months.

Twenty-seven pts. felt relief of symptoms as manifest by decreased pain and/or decreased ascites. Optimally debulked (76-99% or complete) patients showed improved long-term survival as compared to those who were sub-optimally debulked (p Conclusions: Mesothelioma is a rare but lethal disease. Long-term survival can be realized in patients that undergo optimal debulking, without peritonectomy, and receive adjuvant i.p. chemotherapy.

Careful pleural mesothelioma prognosis is necessary

February 6, 2012 – 6:41 am

Pleural mesothelioma is a disease that affects the lining of the lungs, or lung pleura. Sometimes doctors refer to this disease as mesothelioma of the pleura. It is a common misconception that mesothelioma is a type of primary lung cancer; it is not. Mesothelioma is a cancer of the serous membranes. These membranes enclose a number of organs throughout the midsection of the body, including the lungs. The most common type of mesothelioma, pleural mesothelioma, affects the serous membranes of the lungs.

Mesothelioma can also affect the serous membranes surrounding the abdomen, called peritoneal mesothelioma, and the membranes surrounding the heart, or pericardial mesothelioma. When mesothelioma spreads to the lungs from the serous linings of the lungs, abdomen or heart, it is considered secondary lung cancer. Also, pleural mesothelioma is sometimes referred to as an asbestos lung cancer. Technically, cancers that do not originate in the lungs are not considered lung cancer; thus, terms such as secondary lung cancer and asbestos lung cancer (pleural mesothelioma) are misleading. Asbestosis is a type of asbestos lung disease that does originate in the lungs and is often confused with mesothelioma.

pleural mesothelioma prognosis

pleural mesothelioma prognosis

Pleural Mesothelioma Cancer

Pleural mesothelioma cancer represents about 75 percent of all mesothelioma cases. This disease is caused by the inhalation of asbestos fibers, which then settle in the lungs. These asbestos fibers become imbedded in the lining of the lung (the pleura). Over time, they cause chronic inflammation that eventually leads to growth of cancerous tumors or, in some cases, asbestosis.

Pleural mesothelioma prognosis normally appears as multiple tumor masses affecting the parietal surface (outside; further from the lung) and visceral surface (inside; closer to the lung) of the pleura. Typically, the parietal surface has greater involvement than the visceral. There is a slightly higher incidence of mesothelioma in the right lung, apparently due to the fact that the right lung is larger and has a greater amount of pleural surface area. Also, the lower lungs typically show more tumor masses than the upper lung. This is thought to be due to gravitational factors influencing how the asbestos fibers settle in the lungs after they have been inhaled.

Epithelioid malignant mesothelioma-Be alert it

February 3, 2012 – 8:55 am

Mesothelioma is a rare and aggressive form of cancer that is diagnosed in an estimated 2,000 to 3,000 people each year in the United states. It is a cancer of the mesothelium, which is a protective lining around most major organs in the body, including the heart, lungs, and organs in the abdomen. Mesothelioma causes cells of the mesothelium to develop abnormally and to become malignant.

In different regions of the body the mesothelium has different names. The mesothelium of the lungs and chest cavity is the pleura; of the heart it is the pericardium; of the abdominal region it is the peritoneum; and of the tunica vaginalis testis (male) or tunica serosa uteri (female). When mesothelioma occurs in each of the regions, it is named accordingly:Epithelial mesothelioma, also referred to as epithelioid mesothelioma, is the most common form of malignant mesothelioma. It occurs in between 50 and 70 percent of all mesothelioma cases. The cells in this form of mesothelioma closely resemble epithelial cells. Epithelial cells line the organs and cavities in the body. When viewed under a microscope, epithelial mesothelioma cells appear to be well-defined and uniform, with a distinct cell nucleus which can be distinguished. However, the epithelial mesothelioma cells may be mistaken for another type of cancer that occurs in the mesothelium, called adenocarcinoma.

Symptoms of epithelioid malignant mesothelioma may include fatigue, coughing, hoarseness, shortness of breath, chest pain, abdominal pain or swelling, or weight loss. Early symptoms of the cancer may present much like common ailments, such as a cold or flu virus. This can potentially lead to a delay in proper diagnosis.

Epithelial mesothelioma may be diagnosed using a variety of diagnostic tools. Early tests may include blood tests and tissue samples. Ultrasounds, CT scans, MRIs, and PET scans are also tools utilized to diagnose mesothelioma. In addition, specialists may use immunohistochemistry (chemical testing of cells and tissues) or fine needle aspiration (using a needle to withdraw fluid from the body) to diagnose the cancer. Doctors may use a number of diagnostic tests before making an accurate diagnosis of epithelial mesothelioma.

Treatment of epithelial mesothelioma may include surgical removal of a portion of an effected area, chemotherapy, and/or radiation. Some patients may also opt to use alternative medicine or complimentary treatments to ease the pain they experience as a result of their cancer.
