Malignant Mesothelioma Research And Treatment

MALIGNANT MESOTHELIOMA is always research going on in the area of mesothelioma. Scientists are looking for ways to prevent, diagnose, and treat mesothelioma. Despite recent progress, much remains to be learned about the best way to treat these cancers.(MALIGNANT MESOTHELIOMA)

Causes and prevention

MALIGNANT MESOTHELIOMA of the research on mesothelioma has focused on learning exactly how asbestos changes mesothelial cells and their DNA to cause these cancers. (MALIGNANT MESOTHELIOMA) Understanding how these fibers produce cancer might help us develop ways to prevent those changes.

MALIGNANT MESOTHELIOMA role of asbestos in increasing the risk of mesothelioma is a definite public health concern. Researchers are learning more about which fibers can produce cancer, how  MALIGNANT MESOTHELIOMA  cause these cancers, and what levels of exposure can be considered safe.  MALIGNANT MESOTHELIOMA  the dangers of asbestos are known,  MALIGNANT MESOTHELIOMA  can limit or stop exposure in homes, public buildings, and the workplace. Unfortunately,MALIGNANT MESOTHELIOMA  regulations protecting workers from asbestos exposure are much less stringent in some countries than in others.

MALIGNANT MESOTHELIOMA  Research is also under way to clarify the role (if any) of SV40, a virus that has been linked to mesothelioma in some studies.

Treatment

Mesothelioma remains a difficult cancer to treat, and doctors are constantly trying to improve on current approaches.  Mesothelioma roles of surgery, radiation therapy, and chemotherapy in the treatment of mesothelioma are highly debated. Mesothelioma Combinations of these treatments, called multi modality therapy, are now being studied and may provide the most promising option for some patients.

Chemotherapy

MALIGNANT MESOTHELIOMA chemotherapy drugs can shrink or slow the growth of mesothelioma, but in most cases the effects last for a limited time. ( MALIGNANT MESOTHELIOMA ) Several newer chemotherapy drugs, including raltitrexed, are currently being tested in clinical trials, together with other types of treatment.

As mentioned in the section "Chemotherapy," doctors are now exploring giving chemotherapy drugs directly into the chest or abdominal cavity, often right after surgery. In some cases,MALIGNANT MESOTHELIOMA the drugs are heated before they are given. Doctors hope that putting the drugs directly into contact with the tumours may allow them to work better, while limiting the side effects in the rest of the body.

Photodynamic therapy

Another technique now being studied is photo dynamic therapy (PDT). For this treatment, a light-activated drug is injected into a vein. The drug spreads throughout the body and tends to collect in cancer cells.  MALIGNANT MESOTHELIOMA  few days later (usually just after surgery for the mesothelioma), a special red light on the end of a tube is placed into the chest cavity.  MALIGNANT MESOTHELIOMA light causes a chemical change that activates the drug and causes the cancer cells to die. Since the drug is only active in the areas exposed to the special light, this approach may cause fewer side effects than use of drugs that spread throughout all tissues of the body. Several clinical trials are now studying the use of PDT for mesothelioma.

Mesothelioma Stages

There are basically three stages of mesothelioma but we sure
about that if we handle 1st stage of mesothelioma so we handle
it and save the patient going to danger condition.so let see what
the stages ?


Staging is the process of finding out how far the cancer has spread. Staging of mesothelioma is based on imaging studies such as x-rays, CT scans, and MRI scans. The treatment and outlook for patients with mesothelioma largely depends on the stage (extent of spread) of their cancer. Since pleural mesothelioma occurs more commonly and has been studied the most, it is the only mesothelioma for which a staging classification exists.

The staging system most often used for mesothelioma is the Butchart system. This system is based mainly on the extent of the primary tumor mass, and divides mesotheliomas into stages I through IV.


Butchart Staging System

*


*



* Stage I: Mesothelioma is present within the right or left pleura, and may also involve the lung, pericardium, or diaphragm (the muscle separating the chest from the abdomen) on the same side.






* Stage II: Mesothelioma invades the chest wall or involves the esophagus (food passage connecting the throat to the stomach), heart, or pleura on both sides. The lymph nodes in the chest may also be involved.


*



* Stage III: Mesothelioma has penetrated through the diaphragm into the peritoneum (lining of the abdominal cavity). Lymph nodes beyond those in the chest may also be involved.






Stage IV: There is evidence of distant metastases (spread through the bloodstream to other organs).

Another staging system has recently been developed by the American Joint Committee on Cancer (AJCC). This is a TNM system, similar to staging systems used for most other cancers. T stands for tumor (its size and how far it has spread to nearby organs), N stands for spread to lymph nodes and M is for metastasis (spread to distant organs).


TNM Staging System








 Stage I: Mesothelioma involves the right or left pleura. It may also have spread into the lung, pericardium, or diaphragm on the same side. It has not yet spread to the lymph nodes.




 Stage II: Mesothelioma has spread from the pleura on one side to the nearby peribronchial and/or hilar lymph nodes next to the lung on the same side. It may also have spread into the lung, pericardium, or diaphragm on the same side.






 Stage III: Mesothelioma has spread into the chest wall muscle, ribs, heart, esophagus, or other organs in the chest on the same side as the primary tumor, with or without spread to subcarinal and/or mediastinal lymph nodes on the same side as the main tumor. Subcarinal nodes are located at the point where the windpipe branches to the left and right lungs. Mediastinal lymph nodes are located in the space behind the chest bone in front of the heart. Mesotheliomas with the same extent of local spread as in stage II that have also spread to subcarinal and/or mediastinal lymph nodes on the same side are also included in stage III.








* Stage IV: Mesothelioma has spread into the lymph nodes in the chest on the side opposite that of the primary tumor, or directly extends to the pleura or lung on the opposite side, or directly extends into the peritoneum, or directly extends into organs in the abdominal cavity or neck. Any mesothelioma with evidence of distant metastases (spread to other organs through the bloodstream) or spread to organs beyond the chest or abdomen is included in this stage.



Although the recently developed TNM classification is the most detailed and precise, the original Butchart staging system is still used most often to describe the spread of pleural mesotheliomas. Understanding these staging systems for mesothelioma is important both for estimating prognosis, and also for assessing therapeutic options.
Prognostic Factors Younger age at diagnosis, good general state of health and absence of weight loss are associated with a more favorable prognosis.


Mesothelioma are usually of three different cell types (histological analysis): 1) epithelial cell type - has the most favorable prognosis; 2) sarcomatoid cell type - carries the worst prognosis and 3) mixed cell type - has an intermediate prognosis.


Patients should also educate themselves about mesothelioma and treatment options and reach out to available resources to make coping with a mesothelioma diagnosis easier


Well Conditions depend the values what her/him relation follow the patients and Patient also follow the conditons
what did he or she feel ? So life is so short but not easier at that conditions, but we follow the rule so life its so
Easier ...Please save humain beings..
