Radiation

Radiation therapy, or "ionizing radiation", is used to kill cancer cells and to limit the spread of cancer. For patients with mesothelioma, radiation therapy is most often used in conjunction with surgery.

Radiation is often used in conjunction with surgery.

However, in some cases radiation may be used as a stand-alone treatment to relieve pain and other symptoms associated with mesothelioma. In either case, it is rare for radiation therapy to provide more than short-term symptomatic relief.

Mesothelioma patients may receive one of two types of radiation therapies, depending on whether or not they are suitable candidates for either procedure.

External beam radiation therapy is the traditional type of radiation therapy, where tumors are bombarded with beams of radiation to kill cancer cells. Brachytherapy is a newer type of radiation treatment. It involves tiny radioactive rods which are implanted within a tumor to provide a strong, concentrated dose of radiation to tumors while doing very little damage to surrounding healthy tissue.

Chemotherapy

Most forms of chemotherapy involve the intravenous administration of drugs such as Alimta and Cisplatin. Chemotherapeutic drugs are targeted to kill cells that are rapidly dividing by interfering with processes that occur during cell division.

Chemotherapy is an effective treatment option but comes with unpleasant side effects.

However, while cancer cells themselves divide rapidly, so do some types of healthy cells, causing some of the unpleasant side effects that are often associated with this form of treatment. Though older chemotherapy medications seemed to do little to fight mesothelioma, newer chemotherapy drugs are showing much promise.

A relatively new form of chemotherapy called heated chemotherapy is an option for patients with peritoneal mesothelioma.

This treatment is carried out following surgery, and involves the perfusion of heated chemotherapeutic medications into the peritoneum.

Surgery

Surgical treatments for mesothelioma include three main types - diagnostic surgery, curative surgery, and palliative surgery. Some types of surgery fall into more than one category.

Surgery can only be performed during mesothelioma stages I and II.

For example, thoracentesis may be used as a diagnostic procedure, and as a palliative treatment to provide symptomatic relief. Only curative surgery can potentially remove all cancer from a patient with mesothelioma.

However, for curative surgery to be effective, it is particularly important that mesothelioma be diagnosed as early as possible. Unfortunately, mesothelioma is not usually diagnosed until it reaches Stage III or IV, when surgery is not an option.

Mesothelioma Treatment - Overview

There are several mesothelioma treatment options including chemotherapy, radiation, and surgery.

There are several types of treatment available for patients with mesothelioma, some recommended more frequently than others. The most commonly used treatments are surgery, chemotherapy, and radiation therapy. In addition, some experimental treatments are becoming more widely used, or are showing some encouraging results in clinical trials. These treatments include photodynamic therapy, gene therapy, and immunotherapy, among others.

Most of these treatments are not used in isolation. In many cases, treatment may consist of a combination of therapies. For example, surgery to remove as much of the cancer as possible may be followed by radiotherapy or chemotherapy to remove residual cancer cells. This is one of the most common treatment options for mesothelioma among those who are candidates for surgery.

A number of alternative therapies can also be combined with traditional treatment options. Many patients choose to add alternative therapies such as massage, acupuncture, or TENS therapy to their conventional treatment approach in an effort to enhance or compliment the treatment process. A numer of alternative therapies, including aromatherapy, meditation, or yoga, are often added to a treatment regimen to provide pain relief and foster relaxation.

All About Malignant Mesothelioma

Malignant mesothelioma is a rare form of cancer that affects the mesothelial cells of the serous membranes in the body. The most common form of mesothelioma, affecting the lining of the lung, is pleural mesothelioma. Two to three thousand new cases of malignant mesothelioma are diagnosed each year.

The mission of All About Malignant Mesothelioma is to provide a one-stop resource for comprehensive, up-to-date mesothelioma information. We cover the full scope of malignant mesothelioma issues including background, history, risk factors, diagnosis, and treatment. Please recommend the site to someone who may benefit from mesothelioma information.

Introduction to Malignant Mesothelioma

Malignant mesothelioma affects the lining or membranes of certain large cavities in the body. These cavities, called the serous cavities, house certain major organs in the body including the heart, lungs, abdomen and others. The membranes that surround these cavities are called the serous membranes. They serve to protect these major organs from the friction and abrasion that occur as the organs move against each other during typical daily functioning, such as breathing and heart beating. The serous membranes derive from specialized cells called mesothelial cells. These cells form to create the mesothelium, which is the major tissue layer of the serous membranes. Cancer that occurs in the mesothelium tissue is called mesothelioma.

Malignant mesothelioma takes on three forms:

• Peritoneal mesothelioma, in the peritoneum or membrane surrounding the abdomen. A rare form of peritoneal mesothelioma can also affect the male testicles, because the lining around the scrotum is an extension of the peritoneum.
• Pericardial mesothelioma, in the perdicardium or lining surrounding the heart.
• Pleural mesothelioma, which is the most common form of malignant mesothelioma and affects the lining of the lung cavity.

All mesotheliomas are now considered to be malignant, or cancerous. They start as a localized tumor and spread rapidly to include most of the surrounding tissues and organs. Originally, fibrous cists and other non-cancerous growths that appeared in the serous membranes were thought to be mesotheliomas and were termed "benign fibrous mesothelioma" and "multicystic mesothelioma." These conditions are now known not to originate in the mesothelial cells, but other cells within the serous membranes. These conditions are typically localized, non-cancerous and do not spread rapidly.

Etiology of Malignant Mesothelioma

Most cases of malignant mesothelioma are associated with a previous exposure to fibrous minerals, of which asbestos is the most important. There is now indisputable evidence of the role of these fibers in the development of this disease. This has been demonstrated in animal experiments and many other experiments. Not everyone who is exposed to asbestos fibers has developed malignant mesothelioma, suggesting that other factors may also be involved.

Although malignant mesothelioma is rare, it is a serious, deadly disease. It is often in the advanced stages when it is detected, so the outlook for the patients is not as good as it is for the cancers that are detected earlier. The average survival time after detection is 1 to 2 years. This survival time also depends on the type of mesothelioma.
