Other Causes of Mesothelioma
Have you ever had mesothelioma cancer? Or do you know someone who has mesothelioma cancer or asbestos lung disease? If yes, are you or are they aware of the substances that may have caused it? This article shows various elements that people are usually exposed of and therefore causes mesothelioma cancer in their bodies. Asbestos and mesothelioma are very closely related and most victims are open to mesothelioma asbestos exposure. The below are some of the causes of mesothelioma.
Zeolites
One known substance is called Zeolites. Zeolites are silicate minerals which can be related chemically to asbestos or mesothelioma. A common example of Zeolites is erionite, which can be found in the soil in most areas and places in Turkey. Due to high exposure to mineral, the exposure of mesothelioma in these places has also been high.
Radiation
According to some published reports, high amounts of radiation in the chest or abdomen and injection of thorium dioxide or Thorotrast causes mesothelioma. Until the 1950s, this substance was still being used by physicians in X-ray examinations. Because the substance has been found out to cause mesothelioma cancer, the use of it was prohibited for several years.
SV40 virus
As stated by a few studies, people who have been infected by the simian virus 40 or SV40 have been considered as a risk of acquiring mesothelioma. Vaccines for polio that have been injected between the years 1955 and 1963 were said to be infected by the simian virus. Around thirty million people in the United States of America have been contaminated by the simian virus by now.
According to a few laboratory studies, the simian virus can trigger mesothelioma cancer. This may be illustrated by this example: an intended infection with simian virus of laboratory animals like hamsters. Laboratory animals like these can cause mesothelioma to grow. Examiners also have pointed out that the simian virus can influence the mouse cells to grow in dishes which can be extremely cancerous. Because this is caused by the substance asbestos, it only adds to the cancer-causing effect of the simian virus on these mouse cells. The simian virus DNA has also been found by some examiners in human mesotheliomas. But only fragments of these DNA can be located in a number of human tissues which are non-cancerous.
Still, the biggest researches and studies regarding human mesothelioma have not discovered the risk for mesothelioma or other kinds of cancers among individuals who have acquired the infected vaccines as children. The peak range for diagnosing this kind of condition is between fifty to seventy years. According to a number of researchers, this problem may stay unsettled until most of the people who have been exposed to the simian virus between the years 1955 and 1963 arrive to the age range.
However, there is no assurance that mesothelioma have really been caused by the simian virus though experts have claimed it must be so. Researchers still have no valid evidence that the simian virus is responsible for some types of mesotheliomas. Researches have still been ongoing in this vital issue. Researchers are still currently examining other possible causes of this condition and ways on how to solve these issues.

Extrapleural Pneumonectomy
Another new mesothelioma treatment is of surgical method that includes lung removal is the penumonectomy or also called pneumectomy. This procedure was first done in 1985 in order to remove the tissues in the lungs. A type of pneumectomy that has been widely used to treat malignant pleural mesothelioma for the last thirty years is the extrapleural pneumonectomy.
While cancer in the lungs has an effect on the lung tissues, malignant pleural mesothelioma is affected in the pleura, a serous membrane that separates the lungs from other body organs in the abdominal area and the chest. Though mesothelioma is not really a lung cancer, it potentially spreads to the lungs once the cancer in the pleura has metastasized. That is the reason why a standard pneumonectomy needs to be performed to remove the cancerous lung. An extrapleural pneumonectomy, on the other hand, is needed for removing the cancerous pleural tissue and the lung nearest to the affected part. The removal of the lung in extrapleural pneumonectomy is done in order to prevent the malignant mesothelioma from spreading.
There is no perfect treatment modality that can cure malignant pleural mesothelioma. The best way for the patient to survive is to use a trimodality treatment where chemotherapy and radiation therapy are performed along with extrapleural pneumonectomy.
The Candidates for Extrapleural Pneumonectomy
Extrapelural pneumonectomy surgery can be given for only few selected patients. Patients who are currently in the early stage of the malignant pleural mesothelioma with respectable cancer formation are the most likely candidates that can undergo extrapleural pneumonectomy surgery.
The most well-known cancer cell subtypes that are linked with malignant mesothelioma are epithelial cancer cells, compared to the other serious subtypes such as desmoplastic and sarcomatous. Moreover, the operative centers want to use extrapleural pneumonectomy procedures that patients with epithelioid cancer contain due to the low post-extrapleural pneumonectomy survival time of the other two.
The Procedure for Extrapleural Pneumonectomy
Because of many preoperative and postoperative treatments, extrapleural pneumonectomy surgeries become very persistent. In order to limit the preoperative pain and discomfort, patients are given general anesthesia. Also, postoperative pain is managed by inserting a thoracic epidural catheter before the operation starts.
The extrapleural penumonectomy surgery starts as it enters the chest and passes by the unobstructed sixth rib where the sixth rib is taken out occasionally. The process of extrapleural dissection begins which the surgeon provides intensive care in order to avoid entering the pleural cavity. Entrance to the pleural cavity may only lead to spillage or malignant cells within the active field. The removal of the pleura or the lining of the lung, the lining of the heart or pericardium, the diaphragm or muscles that aids in breathing, and the appropriate lung depends where the affected part of the chest is located.
Postoperative Care for Extrapleural Pneumonectomy
People’s recovery standard pneumonectomy procedure is similar to the recovery experienced by postoperative care of extrapleural pneumonecotomy patients. Postoperative patients are in danger of developing low blood pressure or hypertension which results from reconstructing the pericardium. Once a patient of postoperative extrapleural pneumonectomy experiences hypotension, follow-up has to be done immediately.
The most vital postoperative concern is managing the patient’s pain. Pain has to be controlled in order for it to lead to the breakdown of the residual lung. This is called the postoperative atelectasis. Pulmonary rehabilitation is used to restore the function of the heart to its normal state. This usually takes place on the second day, preceding extrapleural pneumonectomy.
Moreover, trimondality therapy is the best and most efficient method in order for the first stage malignant pleural mesothelioma victims to survive. Once the therapy is successful, five years to survive is possible for the patients in comparison to the one year span for survival that is common with malignant mesothelioma.
Thoracentesis Procedure
One procedure that is used to decrease the symptoms and discomforts that pleural mesothelioma brings is thoracentestis. This condition’s most frequent symptom is pressure which results from the mounting up of fluid in the middle of the parietal pleura or the lining that covers the chest wall, and the visceral pleura, or the lining that covers the lungs. The mounting of excess fluid is named pleural effusion.
Thoracentesis Procedure
During the thoracentestis treatment, the fluid that is mounted in pleural effusion is reduced through lessening the pressure exerted on the chest wall and the lungs. In order to perform the treatment, inserting a catheter or a syringe in the middle part of the chest wall and the lungs is needed in order to allow aspiration or have the fluid removed.
In the middle of the lung area and the ribs, a needle is usually placed in from the back. The part where the needle will be injected is sterilized and an anesthetizing medication is injected into the little area of the skin. This procedure is not lengthy and moderately painless. It also has less complication. The procedure is often described as pleural fluid aspiration.
Pleural Effusion
The cells that surround the serous membranes’ walls and part the major body organs are the mesothelial cells. They produce little amount of fluid that are used to serve as a lubricant between the different body organs and the chest wall. Once an excessive mounting up of fluid takes place, pleural effusion happens. This is classified into two major kinds: exudates and transudates.
The first type of fluid which is the exudative fluid is cloudy and has various cells and proteins. This fluid is linked with diseases concerning mesothelial cells such as mesothelioma. A transudative fluid, on the other hand, is clear and most common to the processes of mesothelial cells. This fluid builds up not due to the disease in the mesothelial cells but due to the imbalance that is present between the making and elimination of the transudative fluids.
Enough amount of fluid that the mesothelial cells produce is usually immersed by the blood and the lymph vessels so that the pleural gap is not filled or extended in an entirely balanced system. Congestive heart failure is one of the most common causes of excessive transudative fluid. What happens in congestive heart failure is that the heart no longer pumps blood through the lungs properly. Also, there is no adequate blood flow that can suck in the fluid found in the pleural gap.
Diagnostic Thoracentesis
Moreover, thoracentesis can be carried out as a diagnostic method. This procedure is utilized in the same way as the treatment is utilized but there is less removal of fluid. Usually, the fluid is brought to a pathologist for analysis after it has been removed. Once a pleural effusion is found, diagnostic thoracentesis is executed.
Pleural effusions are symptomatic amounted to abnormalities that are related to mesothelial cells such as mesothelioma. In various cases where cancer is at hand, negative or inconclusive results come out of the examinations of the effusions. There are only fifteen percent of the cases that are cancer-related come out with a definitive diagnosis. Usually, biopsy of pleural material is a must in order to get a specific diagnosis of mesothelioma.
Mesothelioma Chemotherapy
The lethal cancer named malignant mesothelioma can be cured through chemical substances in mesothelioma chemotherapy. In spite of the various numbers of treatments for mesothelioma, there are only a few that proves to be successful in curing the disease. Mesothelioma chemotherapy is classified into two categories: traditional mesothelioma and new mesothelioma treatments.
Ever since the early 1940s, chemotherapy has been widely used in curing cancer. But because of scientific improvements and a better understanding of the characteristics of the disease, a continuous research and development of targeted chemotherapy agents are allowed recently. The treatment that chemotherapy provides becomes most useful when the cancer cells are moderately young and there is still no formation of a solid tumor mass.
Many mesothelioma chemotherapy drugs are used in treating the rare type of cancer. However, none of those drugs have been effective in treating the malignant mesothelioma. Similar to standard chemotherapy agents, these drugs are impaired in cell division and initiated programmed cellular death or also called apoptosis. The anti-angiogenesis mesothelioma chemotherapy drugs, for instance, prevents the new blood vessels to form in a process called angiogenesis. These drugs also prevent tumors from creating a trail where nutrients are received and oxygen passes through which are necessary once the tumor has grown and continue to spread.
Cisplatin is one of the most traditional chemotherapy drugs that is used to treat malignant mesothelioma. It is part of the family of three comparable drugs, including Carboplatin and Oxaliplatin. It cross-links DNA in a number of ways which prevents fast division of cells and duplication of DNA that aids in further cell division. Other recent chemotherapy drugs such as Alimta or pemetrexed, Onconase or ranpirnase and Veglin are in conjunction with Cisplatin.
Types of Treatment for Mesothelioma Chemotherapy
The Mestothelioma Chemotherapy treatments are not always geared for the intention to heal. There are more common mesothelioma treatments that are used such as Combined Modality Chemotherapy which is usually partnered with other types of treatment like radiation therapy and surgery. One example that involves different kinds of therapy is the trimodality therapy which contains the use of chemotherapy, radiotherapy, and surgery. Another type of therapy is the intensity modulated radiation therapy or the IMRT which is also a radiotherapy that is more advanced and uses computer-controlled linear accelerators while minimizing the dose to surrounding normal critical structures. The other kind of treatment is called Neoadjuvant chemotherapy which is also called preoperative chemotherapy with the intention to shrink the size of the tumor mass before surgical treatment takes place. Adjuvant chemotherapy is another type of therapy that is also called postoperative chemotherapy. This therapy is utilized after a surgical treatment once a returning risk of cancer is found. Palliative chemotherapy, on the other hand, is a kind of mesothelioma chemotherapy that uses a palliative technique where it emphasizes on curing the symptoms more rather than the whole disease.
The dosage for chemotherapy differs based on the patient’s body surface area or BSA, which determines an approximate body volume. This can give the perfect balance of chemotherapy treatment and at the same time, avoiding the toxic side-effects.
Side Effects of Mesothelioma Chemotherapy
When a person undergoes chemotherapy, there is an expectation of physical and mental exhaustion for patients. Chemical treatments that are constant entail the following side effects: cardiotoxicity, constipation, diarrhea, hair loss, hepatoxicity, increased risk of cardiovascular disease, lowered number of red blood cells or anemia, nausea, nephrotoxicity, ototoxicity, secondary neoplasm, vomiting, and a weakened immune system.
The chemotherapy treatments all depends on the patient and the severity of the condition which can usually be managed on both an in-patient and out-patient basis.
