Mesothelioma Stages


Traditionally, these mesothelioma stages measure only the tumor mass under the butchart system. A second system, the TNM system, is concerned with the growth of lymph nodes that filter out harmful substances from the body and form metastases or the extent of the spread of the cancer. Another system, called the Brigham system, focuses on surgical options and the extent to which lymph nodes are affected. Mesothelioma is a cancer that affects the thin membrane that protects some of the body's most important organs, including the lungs, abdomen, and heart.

The treatment of this disease includes surgery, chemotherapy, and radiotherapy. All staging systems refer to pleural (breast) mesothelioma, the most common form of the disease, and use four stages. There are no established the staging systems for peritoneal or pericardial mesothelioma stages. The first two levels for Butchart and TNM are quite similar.

Mesothelioma Stages

Prognoses, survival rates and life expectancy decrease with increasing number of stages. The mesothelioma runs in four stages. Mesothelioma stages refer to categorizing the malignant mesothelioma according to the extent of the disease in the body of a patient. Staging is a process common to all cancers. Although specific staging systems are often developed based on the characteristics of specific cancers such as mesothelioma stages. 

Early Stages of Mesothelioma

Early-stage patients can benefit from surgery by living longer and experiencing fewer symptoms. Patients in advanced stages benefit more from a treatment that focuses on the treatment of symptoms. The goal of treatment at all stages is to improve the quality of life and help people to live longer. The stage of a mesothelioma tumor describes how far away it has been from the point where it first appeared in the protective layer of the lung, abdomen or heart. The spread of mesothelioma is called metastasis. The further the mesothelioma has spread, the later the doctors develop the disease. Mesothelioma stages can be divided into four stages that indicate how far the cancer has progressed in the body.

Mesothelioma stages are part of the diagnostic process and a critical component in the development of a patient's treatment plan. Cancer staging is an integral part of the diagnosis and treatment of mesothelioma. The most of common treatment for mesothelioma stages is chemotherapy.

The surgery is often combined with chemotherapy and radiation therapy to kill more cancer cells. In clinical trials, new therapies such as immunotherapy are being tested. You knowing how far the cancer has spread helps doctors decide which treatments to use. For example, doctors use the cancer stage as a guide to decide whether a patient is likely to benefit from surgery.

Stages of Mesothelioma

Doctors use imaging tests and biopsies to determine your stage of cancer. The results of your diagnosis will help you to decide which treatments will fit your needs and which will be the best prognosis for your prognosis. The stages of the pleural mesothelioma depend on the size of the tumors and their spread. The location and size of tumors have a direct impact on the symptoms a person feels.

Mesothelioma consists of four stages in which physicians can determine the extent of cancer in the body. At diagnosis, the doctor identifies the stage with a number between 1 and 4, with grade 4 being the most severe and deadly form.

Stage 1

There is no spread to the lymph nodes and the cancer is localized on one side of the body. The tumor is in one place and the cancer has not spread. Surgery is may be an option to remove the tumor. The main operation to remove the cancer is the first line of treatment. Doctors usually recommend an aggressive multimodal approach including surgery, chemotherapy, radiotherapy or immunotherapy. Pleural the lining is a wet, thin membrane between the lungs and the walls of the chest cavity. Its purpose is to protect the lungs from abrasion. There are two layers of this lining (pleura): one that lines the lungs and one that lines the chest wall.

During normal breathing, these coverings easily slip over each other. When malignant mesothelioma develops in the lining (pleura), it thickens and can press on the lungs. Liquid may accumulate between the pleura. At this point you may experience difficulty in breathing, chest pain, coughing and hoarseness. The TNM staging system divides Tier I into two categories that describe where the cancer is located. This is the earliest phase. Stage 1 patients have the most treatment options. The tumor growth is initially in a single area.

The life expectancy of a mesothelioma in stage 1 is significantly better than in later stages. It is difficult to get the cancer so early because people with this stage usually have no symptoms.


Stage 2

The tumor is bigger and has attacked nearby organs like the lungs or the diaphragm. Surgical resection may still be possible, but more difficult. The available treatment options are generally the same as those for stage 1 mesothelioma. The mean life expectancy in stage 2 is 20 months with surgery. Mesothelioma is still localized on one side of the body, but there are signs of metastasis near lymph nodes. Stage 2 mesothelioma symptoms are vague and mild, and patients and doctors often confuse them with signs of other illnesses such as the flu. Aggressive treatment options are still an option.


Stage 3

The mesothelioma cells have invaded nearby areas such as the chest wall, esophagus or lymph nodes. If the cancer progresses to stage 3 mesothelioma, it may have spread to multiple tissues, organs, and lymph nodes in the same body region in which it was formed. Surgery is generally no longer an option. In pleural mesothelioma patients may have difficulty breathing and chest pain, even when resting. Surgery is no longer possible and the cancer has spread to other parts of the breast, including the heart.

Complaints can also occur in other parts of the body. The first significant signs of metastasis have occurred. The mesothelioma has spread to lymph nodes and surrounding organs. The surgical options are limited. Some level 3 cancer patients are not suitable for surgery and other aggressive treatments. At this time doctors offer palliative options.


Stage 4

Mesothelioma cells have spread to different areas of the body. The surgery is not an option, and most treatments focus on palliative care. In stage 4 mesothelioma, cancer has spread to other parts of the body. Cancer can be present in the liver, brain, bone or elsewhere. The surgery is not possible and the cancer has spread to other parts of the body. Patients may experience extreme respiratory and swallowing difficulties, digestive problems and severe pain.

The mesothelioma stages have spread to the other side of the body. In stage 4 mesothelioma patients, physicians typically rely on palliative treatments for pain relief and control of other symptoms. Most stage 4 mesothelioma patients are not suitable for surgery. The treatment options for patients in stage 4 mainly include the relief of symptoms.


Characteristics of the 4 Stages

Stage 1

Stage 1 mesothelioma patients have the best life expectancy. There are no metastasis or lymph node spread and curative surgical treatment is still an option. Cancer is localized on one side of the body.

  • Localized
  • No metastasis or lymph node involvement
  • Curative treatment options
  • Best prognosis

Stage 2

The tumor has grown beyond the point of origin but the involvement of the lymph nodes is minimal. Cancer is still localized on one side of the body. Curative operations are still an option.

  • Localized
  • The tumor metastasized to lymph nodes with minimal spread
  • Curative treatment is an option

Stage 3

The palliative and non-surgical treatments are typically used at this stage. The tumors has spread to surrounding organs and lymph nodes. The cancer is still on one side of the body.

  • Isolated on one side of the body
  • The tumors has spread to nearby organs and lymph nodes
  • The treatment options are usually palliative and non-surgical

Stage 4

Tumors have spread to several organs and have spread through the lymphatic system and blood vessels. The cancer has spread to both sides of the body. Palliative, radiation and chemotherapy treatments are available.

  • Sprinkle on both sides of the body
  • The tumor has spread to several organs, lymph nodes, and blood vessels
  • The treatment is usually palliative

Pleural Mesothelioma Stages

The malignant pleural mesothelioma, the most common type of mesothelioma stages. Is the only type of mesothelioma that currently has an approved staging system. Many staging systems have been developed and used for pleural mesothelioma stages in recent decades. Over to the years, several different pleural mesothelioma staging systems have been developed. Three of most commonly used systems are the Butchart system, the Brigham system and the TNM system.

Although similar, they vary slightly in the definitions of the individual stages of the mesothelioma. Each staging system has specific criteria for the different phases. However, in all staging systems, it is apparent that as the number of stages increases, the disease is generally more advanced, more difficult to treat and has a poorer life expectancy.

Mesothelioma Stages
Doctors use 4 stages to describe the spread or metastasis of the pleural mesothelioma. At each stage it is indicated how far the tumor has moved from the place where it first appeared in the pleura, the protective lining of the lung. The pleural mesothelioma is classified from stages 1 to 4. Level 1 pleural mesothelioma is localized in the pleura. As the cancer spreads further from where it originates, the stages progress. Your doctor may also refer to the cancerous stage of mesothelioma as early or advanced. The early stages of mesothelioma include stages 1 and 2, while advanced stages include stages 3 and 4.

Stage 1 Pleural Mesothelioma

Stage 1 pleural mesothelioma is classified by lack of metastases and divided into stages 1A and 1B. Patients diagnosed with stage 1 mesothelioma have the most favorable prognosis compared to advanced stages of the disease. Stage 1 mesothelioma tumors are more likely to respond to curative treatments - such as surgery, chemotherapy or radiotherapy - because the tumor is confined to the lining of a lung and is easier for doctors to remove. Stage 1A includes only the outer layer of the pleura (parietal).

When the cancer metastasizes to stage 1B, the inner layer (visceral) of the pleura is affected. The growth of stage 1 pleural mesothelioma is limited to the lining of a lung. During Stage 1 mesothelioma, the tumor may also spread from the lung outer skin (closer to the chest wall) to the inner lung (closer to the lung itself). The curative treatment options are available for stage 1 mesothelioma patients.

Stage 2 Pleural Mesothelioma

In stage 2 pleural mesothelioma has begun to metastasize to other areas of the chest wall and lungs. Treatment options at this stage still include surgeries such as extrapleural pneumonectomy or pleurectomy, but are more limited than stage 1 mesothelioma. It is still located on only one side of the chest. Patients diagnosed with stage 2 pleural mesothelioma have a similar prognosis to stage 1 mesothelioma patients.

In stage 2 mesothelioma patients are still eligible for curative treatments that can extend life expectancy. Stage 2 mesothelioma is considered the first advanced stage of mesothelioma because of its metastasis. As in stage 1, stage 2 tumor stage growth still occurs in the lining of a lung. At this point, however, the cancerous cells may have spread to the walls of the ribcage, diaphragm, near the patient's lymph nodes or into the lungs themselves.

Stage 3 Pleural Mesothelioma

Level 3 is more locally aggressive and can spread to other nearby organs. The prognosis of patients diagnosed with stage 3 mesothelioma is closely related to age and general health. Stage 3 pleural mesothelioma has not spread to the other side of the ribcage, but there is definite metastasis of the lymph nodes. In stage 3, a tumor has spread to one side of the body and has invaded at least one or all of the following areas: a lung, the diaphragm, to nearby lymph nodes, and the protective lining of the heart.

Those who are healthy and can withstand surgery. May be considered for treatments that extend life expectancy well beyond the average. Surgery is not always a treatment option for patients in stage 3 mesothelioma. 

Stage 4 Pleural Mesothelioma

The treatment options are palliative at this stage mainly due to the aggressive nature of the cancer. Patients diagnosed with stage 4 mesothelioma have an average life expectancy of less than 12 months. Stage 4 mesothelioma patients may not be suitable for traditional curative treatment options such as surgery. The stage 4 pleural mesothelioma is the most advanced stage. The growth of a stage 4 mesothelioma tumor has spread far beyond the lining of a lung. At this stage, cancer cells and secondary tumors may be present in larger portions of the chest wall, diaphragm, lining of the heart and lymph nodes far from the lining of the lung.

Patients may experience more severe symptoms such as difficulty swallowing and coughing blood. However, patients have other options. Palliative treatments alleviate the pain caused by the disease and in some cases have shown prognostic benefit. The main treatment options for stage 4 mesothelioma patients are chemo and radiation.

Peritoneal Mesothelioma Staging

After a second opinion, the new doctor noted that mesothelioma was not as much metastatic as originally thought. Doctors usually do not use stages to describe the spread of peritoneal or pericardial mesothelioma. Both are relatively rare compared to pleural mesothelioma, which accounts for 75 percent of all cases. She was diagnosed with a localized mesothelioma because her doctor considered it operable. There is no accepted system for the staging of peritoneal mesothelioma.

This type of mesothelioma stage is clinically defined by whether it is local or metastatic. In patients with peritoneal or pericardial mesothelioma, a localized or advanced mesothelioma is generally described. An experienced physician can still determine how far the mesothelioma has spread and what treatments are best for improving the prognosis. However, physicians may label peritoneal mesothelioma at a stage that they believe is appropriate depending on how much the cancer has metastasized. 

TNM Staging System

Both of the AJCC and IMIG have approved the staging system for universal use. The system is updated most frequently. The staging system of the American Joint Committee on Cancer (AJCC) highlights three key factors in the development and spread of pleural mesothelioma. The most well-known staging system for pleural mesothelioma is known as the TNM staging system of the American Joint Committee on Cancer (AJCC). TNM system is the most commonly used system. It was developed by the American Joint Committee on Cancer (AJCC) and is similar to the Brigham system.

After categorizing a tumor for each individual group (T, N, and M), the physicians assign the tumor a total group group of 1 to 4. They assign the stage group by combining the T, N and M values of the tumor. A lower grouping number means that the tumor has not spread widely. It can also be referred to as the International Mesothelioma Interest Group (IMIG) staging system.

The Brigham Staging System

In Brigham staging system is another older staging system for pleural mesothelioma. First and foremost, it is about whether a tumor can be surgically removed or not (levels 1 and 2). The Brigham system, which David Sugarbaker at Brigham & Women's Hospital at Harvard has determined the likelihood of surgical options. It is a four-step system that takes into account the location, size and spread of the cancer. Doctors use the Brigham system to describe how the spread of a tumor affects surgical removal.

The Brigham system divides the pleural mesothelioma into four stages. The system also notes whether the cancer has spread to the lymph nodes, which usually indicates a later stage that is unlikely to be viable for surgery. The patients who undergo surgical resection have a better prognosis than patients who do not undergo surgical resection.

The Butchart Staging System

As the oldest and most common staging method, doctors use the Butchart system to describe the location of the main tumor. In The Butchart staging system is the oldest staging system. It is usually based on the extent of the primary tumor. The Butchart system was developed by Dr. Ing. Eric Butchart develops and is the original mesothelioma staging system. It is consists of four stages and focuses on the location of the main tumor. This system is limited in that the researchers developed it from a small patient sample. In addition, it has been developed prior to the use of advanced imaging techniques such as CT scans. Instead of how big it is or how far it has spread.

Mesothelioma Stages Symptoms

The symptoms caused by the spread of mesothelioma are metastatic. As a tumor grows, you will feel more symptoms and they will appear more often. The people wonder if they can determine their stage based on their symptoms. The unfortunately, the symptoms of mesothelioma are not strongly correlated with the stages. The physicians divide metastatic symptoms into two general categories: early stage and advanced stage. In the early stages of metastasis, the symptoms of a pleural mesothelioma feel as if they are caused by other lung diseases such as pneumonia or asthma. In general, early symptoms include symptoms caused by stage 1 and 2 mesothelioma, while stages 3 and 4 occur in the advanced stage.

Stage 1 mesothelioma has no symptoms. Difficulty the breathing, dry cough, wheezing, fluid around the lungs and chest pain. In rare cases, patients may experience symptoms that are similar to a common cold, such as shortness of breath during exercise or mild cough. One of the reasons why mesothelioma is diagnosed at a late stage is the fact that the early stages of mesothelioma do not cause any symptoms. The cancer is small in the early stages and does not affect the body like larger late-stage tumors.

Extreme breathing difficulties, difficulty swallowing, severe chest pain, loss of appetite, weight loss, muscle weakness, nocturnal sweats. Symptoms caused by advanced mesothelioma are more common and more specific than those caused by early-stage mesothelioma.


Treatment by Mesothelioma Stages

The stage of mesothelioma of a patient is one of the most important factors in defining a treatment plan, in addition to the type and cell type and the general health of the patient. Early stages of mesothelioma often enable more aggressive curative treatment options, such as: Surgery and systemic chemotherapy. Patients diagnosed earlier may be advised to undergo surgery, followed by chemotherapy and / or radiotherapy to improve prognosis. Emerging the treatments, including immunotherapy and photodynamic therapy, have shown promise even for patients with more advanced disease.

In later stages, chemotherapy alone or with radiotherapy is the standard of care and can be used palliatively. In recent years, more clinical mesothelioma studies have achieved success in extending life expectancy with new treatment combinations as well as other standard treatment methods. However, patients whose diagnosis is closer to the final stage of mesothelioma often receive palliative treatments to help them feel well and improve their quality of life.

Stage 1 Mesothelioma Treatment

If this cancer is diagnosed in stage 1 mesothelioma, surgery is often a good option because the cancer is localized. Surgery is the most commonly recommended treatment for pleural mesothelioma patients with stage 1 mesothelioma diagnosis. Oncologists and thoracic surgeons, who are usually part of a treatment team, will recommend surgery. If the cancer occurs only in part of the breast lining.

The most of common surgical procedures are pleurectomy / decortication or extrapleural pneumonectomy. If necessary, doctors can also recommend chemotherapy or radiation after surgery. This part of the lining and some of the surrounding tissues can be removed.

Stage 2 Mesothelioma Treatment

Stage 2 mesothelioma is considered advanced. Patients with stage 2 mesothelioma usually have a wide range of treatment options available. Chemotherapy and radiotherapy are the most common treatments. In stage 2 mesothelioma, surgery is still a good option because the cancer has not spread to the abdomen or any other location below the breast. Surgery may or may not be a viable treatment option at this time.

Experimental treatments may also be available to slow the progression of the disease or relieve pain. The treatment focuses on alleviating painful symptoms and treating the cancer through surgery, chemo and radiation.

Stage 3 Mesothelioma Treatment

The treatment options for stage 3 mesothelioma patients are primarily designed to improve patient comfort and improve quality of life. Systemic chemotherapy can be used to kill the cancer cell. Stage 3 mesothelioma patients may want to participate in clinical trials testing new ways to combine different therapies. Surgical procedures such as pleuralectomy or pleurodesis can be used to drain fluid and provide more comfort to the patient.

And test new drugs, vaccines and surgical and radiation techniques. While radiation can be used to shrink tumors, to reduce the pressure on the internal organs. On the website cancer.org, you can search for clinical studies for specific cancers and cancer stages.

Stage 4 Mesothelioma Treatment

Therapies such as chemo and radiation are usually not offered at this time, unless they are needed to support the pain management goals. Since the focus is on the treatment of pain and palliative care at this stage, surgery may be considered if the pain is alleviated. Many families seek support from a local hospice program that focuses on patient care, pain management, and the support of patients and family members at this difficult time.

Mostly this involves draining fluid that accumulates in body cavities, but surgical procedures can also be used to remove diseased organs and linings that contribute to pain. The patients with stage 4 mesothelioma may also be interested in participating in specialized clinical trials offered at leading cancer hospitals and centers.

Mesothelioma Stages Are Not a Sentence

The treatment options of each individual depend on the stage of the disease. If you or a relative have recently been diagnosed with mesothelioma, you might want to speak with someone who provides an explanation and context for your diagnosis. Contact us to contact an expert who will help you to understand what your stage means. The mesothelioma can be deadly at any stage - but there is hope. People have found long-term survival in all stages, although less likely in the end-stage of mesothelioma.

The cell type and location of the mesothelioma they have, as well as the patient's age, sex, and overall health. Although mesothelioma staging can provide guidance for a patient's prognosis, it is important to know that the staging systems are only clues.
