What Is Stage 2 Mesothelioma?
Mesothelioma and other cancers are assigned a stage during the diagnostic process. Using imaging scans, biopsies, and additional information, doctors assign a stage based on where the cancer originated and how far it has spread.
Stage 2 mesothelioma is the second of four stages, from early to late. This is still considered an early stage, but the cancer is farther than in stage 1, including to nearby lymph nodes.
During stage 2, patients start to experience mild symptoms of mesothelioma, but these symptoms are not always severe enough to cause concern or lead a patient to seek a diagnosis. If a patient can get a diagnosis during this stage of mesothelioma, the prognosis is typically above average.
Doctors most often use the TNM (Tumor, Node, Metastasis) system to stage pleural mesothelioma from 1 to 4. There is no standard system for staging peritoneal mesothelioma. Doctors usually use a modified form of TNM.
What Are the Characteristics of Stage 2 Mesothelioma?
Stage 2 mesothelioma is a rare diagnosis, but not as rare as stage 1. Most people are diagnosed during the later stages, 3 or 4. During stage 2, patients likely have troubling symptoms, but they might be very similar to more common and less serious illnesses.
There are two scenarios for stage 2 mesothelioma. The first is that the tumors have spread to nearby lymph nodes, to the chest wall near the original tumor, and to one or more of the following areas:
- The pleural tissue around the lungs
- The mediastinum in between the lungs
- The tissue at the top of the diaphragm underneath the lungs
The second scenario is that the tumors are in the chest wall, the pleural tissue, the area between the lungs, and the top layer of the diaphragm on one side of the chest. The tumors have also spread to the diaphragm or lung tissue on just one side of the chest and nearby lymph nodes.
What Are the TNM Designations for Stage 2 Mesothelioma?
Stage 2 mesothelioma can have a combination of TNM designations to describe its characteristics:
- T, for the primary tumor, can be T1 or T2. This means that it has spread within the pleura on one side or, for T2, into lung tissue, the mediastinum, or the diaphragm on the same side of the chest.
- N, to designate lymph node spread, is N1 for stage 2. This means the cancer has spread only to lymph nodes near the primary tumor.
- M, for metastasis, is M0, meaning the cancer has not spread to distant tissues or organs.
Stage 2 Peritoneal Mesothelioma
Doctors may use the Peritoneal Cancer Index, TNM, or a modified combination of the two to stage peritoneal mesothelioma. There are very few cases of this rare mesothelioma type that develops in the abdomen, so there is no official staging system.
Generally, stage 2 peritoneal mesothelioma has primary tumors in the peritoneum, some nearby tissues or organs, and nearby lymph nodes.
Is Stage 2 Mesothelioma Curable?
Pleural mesothelioma is usually considered incurable. Some patients in the early stages achieve remission with aggressive treatment, but there is always a chance the cancer will recur.
The chance of remission in stage 2 is limited but possible. Patients have the best chance of remission if they choose aggressive surgery that removes a lot of tissue along with adjunctive therapies.
Peritoneal mesothelioma patients have a better chance of remission. A standard therapy that involves removing tumors surgically and using regional chemotherapy is effective for many patients in the early stages.
Stage 2 Mesothelioma Symptoms
Symptoms during stage 2 mesothelioma are often more pronounced than in stage 1. They might still seem like the symptoms of something more common and less serious. This is one reason few patients are diagnosed during an early stage. Doctors can easily mistake early-stage mesothelioma for another illness.
In stage 2 of the disease, if the patient has pleural mesothelioma, symptoms may include:
- Chest pains
- Coughing
- Difficulty breathing
- Shortness of breath
- Unexplained weight loss
- Fever
For those with peritoneal mesothelioma, symptoms include:
- Stomach pain
- Bloating
- Irregular bowel movements
- Unusual weight fluctuations
Patients with other types of mesothelioma, such as pericardial, may experience a combination of all of the above, along with sweating and fevers. As the stages increase, these symptoms become more pronounced.
If you’ve been exposed to asbestos, seek medical assistance right away, even if you think your symptoms seem minor.
Mesothelioma symptoms mimic the common cold and flu, so it’s imperative to be proactive instead of assuming that your ailments aren’t dangerous.
Provide your physician with your work history, including all occasions you were exposed to asbestos.
Stage 2 Mesothelioma Treatments
Stage 2 mesothelioma patients still have several treatment options. Many patients qualify for surgery. Even with surgery, most patients receive multimodal treatment, combining one or more therapies.
Surgery for Stage 2 Mesothelioma
Treatment teams almost always recommend surgery as long as the tumor is in one area and the stage 2 patient is in good health. Multimodal treatment with surgery is the best way to extend a patient’s life expectancy. There are a few options for mesothelioma surgery:
- Extrapleural Pneumonectomy (EPP). EPP is the most radical procedure that is not recommended for many patients. It involves removing a lot of tissue, including one lung. It is a risky procedure, and patients must be in good health to be eligible.
- Pleurectomy/Decortication (P/D). P/D is also known as lung-sparing surgery because the surgeon removes all of the pleural tissue but does not remove a lung. They remove a lot of other tissue, so this can still be a risky procedure.
- Cytoreductive Surgery. This type of procedure means that the surgeon removes as much of the cancerous tissue as possible.
Stage 2 Chemotherapy and Radiation Therapy
Surgery for stage 2 of mesothelioma is used along with chemotherapy or radiation therapy. Doctors may also use other emerging treatments, like targeted drugs or immunotherapy.
The other treatments can be used to shrink tumors before surgery or eliminate cancer cells the surgeon could not remove.
Stage 2 mesothelioma patients who do not qualify for surgery due to age, overall health, or other reasons benefit from these other treatments. The standard approach is to use chemotherapy with immunotherapy or radiation therapy.
What Is the Prognosis for Stage 2 Mesothelioma?
The prognosis for any stage of mesothelioma is usually not positive. It is better for patients in stages 1 or 2, but is usually still considered terminal.
How Long Can You Live with Stage 2 Mesothelioma?
Life expectancy is highly variable with mesothelioma. Each patient’s estimated life expectancy is based on individual factors like age, health, and treatment choices.
The stage is one of the most important factors in estimating life expectancy for mesothelioma patients. According to the American Cancer Society (ACS), stage 2 patients have a life expectancy, on average, of about 20 months.
These statistics are not set in stone; each individual’s life expectancy can vary. While some patients may be given a life expectancy of months, they may go on to live many years.
Patients in stage 2 mesothelioma have reason to hope. They still have many treatment options and a decent prognosis. It’s important to start treatment as soon as possible.
What Is the Survival Rate of Mesothelioma at Stage 2?
Another useful statistic for determining prognosis is the survival rate. The five-year-survival rate is the percentage of patients from a large group still alive five years after their diagnosis.
The five-year survival for stage 2 mesothelioma of all types is between 16% and 24%. Survival rates are higher for peritoneal mesothelioma patients.
How Quickly Does Stage 2 Mesothelioma Progress?
Mesothelioma initially progresses slowly. The latency period, the time from asbestos exposure to diagnosis, is usually several decades. Once symptoms are obvious, however, mesothelioma progresses rapidly.
Stage 2 mesothelioma can progress to stage 3 within months or even weeks. This is why getting diagnosed and beginning treatment as soon as possible is so important.
How to Improve Your Stage 2 Mesothelioma Prognosis
Being diagnosed with mesothelioma often feels like you have no control over how your disease progresses, but this isn’t true. Stage 2 still gives you a lot of treatment options. To improve your prognosis, do the following:
- Start treatment as soon as possible to slow the spread of this aggressive cancer.
- Choose the most aggressive treatments you are qualified for and can tolerate.
- Work with mesothelioma specialists, who have the most experience helping mesothelioma patients.
- Work with a team of specialists, who can provide a range of complementary treatment options.
- Ask your medical team about alternative and mental health therapies that can help you manage symptoms and cope with treatments.
- Make lifestyle choices that optimize your health, like eating well and getting enough sleep. Patients in better overall health have better outcomes.
It is important that you talk to your medical team about your treatment goals. They can help you choose the right treatment plan if you want to extend your life. You do not have to choose aggressive treatments with a lot of side effects. The choice is yours, so make sure your doctors understand your goals to help you achieve them.
