Mesothelioma Survival Rate

Mesothelioma is a deadly cancer that’s usually brought on by asbestos exposure. This cancer occurs in the lining of the lungs, stomach, or heart and it is a very aggressive and unlucky disease for patients with mesothelioma. Knowing survival rates is essential for patients and their families to set realistic expectations and guide treatment planning.

The rates of survival are statistics that calculate how many patients survive during a particular period after being diagnosed. The most frequently used survival rates are the 1-year and 5-year survival rates. 1-year survival rate is the percentage of patients who survive for at least one year after diagnosis; 5-year survival rate refers to those who survive five years or longer.

These metrics are needed to estimate treatment efficacy and determine the disease’s overall outlook. Survival is generally low in mesothelioma because the disease is aggressive and has a late diagnosis.

But those rates depend on several variables, such as type of mesothelioma, stage of diagnosis, patient health, and treatment.

Factors Affecting Mesothelioma Survival Rates

Patients and families need to know the causes of mesothelioma mortality. These include diagnosis stage, cell type, age, general health, sex, and therapy for mesothelioma cancer.

Survival rates depend heavily on the stage of mesothelioma at diagnosis. Four stages of Mesothelioma are typically seen:

• Stage I: Localized, no-spread cancer. Mesothelioma in its early form is comparatively less refractory, and pleural mesothelioma is more likely to survive.
• Stage II: Cancer has reached nearby tissues but is still quite local.
• Stage III: Cancer has invaded lymph nodes and tissues around the site.
• Stage IV: The cancer has spread to distant organs.

Mesothelioma Cell Type: There are three main types of cells in mesothelioma, each of which has its own survival rate:

Epithelioid Mesothelioma: This is the most common and the best prognosis type. Mesothelioma patients with epithelioid cell types live the longest of all mesothelioma lives.

Sarcomatoid Mesothelioma: This type is more aggressive and treatment-resistant, and the outlook is worse.

Biphasic Mesothelioma: This one has epithelioid cells and sarcomatoid cells. The outcome is a function of the proportion of the two types of cells; the higher the percentage of epithelioid cells, the better.

Age and Overall Health: Age and general health are the most important predictors of mesothelioma survival. Younger patients and those who are in better health do better. This is because they’re more apt to resist aggressive care and bounce back faster. Likewise, old patients or people with underlying medical conditions might be less tolerant of treatments and therefore die early.

Gender Differences: There have been gender differences in the survival rate of mesothelioma, and the average lifespan for women is better than for men. The reasons for this inequality could be a number of things:

• Hormonal Differences: Estrogen may play a protective role in women.
• Occupational Exposure: Men were at higher risk of asbestos exposure since they worked in the construction and manufacturing sectors.
• Health Behaviors: Women might take an active role in going to doctors and following the treatment regimens.

Treatment Options: The choice of treatment options significantly impacts mesothelioma survival rates. Common treatments include:

• Mesothelioma Surgery: Treatments such as pleurectomy/decortication (P/D) and extrapleural pneumonectomy (EPP) may be used to remove the tumors and prolong survival, especially in a very early stage.
• Chemotherapy: Chemotherapy — which typically includes the combination of chemotherapy agents such as pemetrexed and cisplatin — shrinks tumors and prolongs life.
• Radiation Therapy: You can use radiation to kill the cancer cells, this is often combined with surgery and chemotherapy.
• Immunotherapy Treatments: There are some promising new treatments, such as immunotherapy in clinical trials. They are therapies to boost the immune system to fight off cancer.

Statistical Overview of Mesothelioma Survival Rates

Patients, carers, and healthcare professionals all need to know the statistical picture of mesothelioma survival. In this article, we will discuss the rates of survival in pleural and peritoneal mesothelioma, compare these rates, and break them down by stage of diagnosis.

Average Survival Rates for Pleural Mesothelioma: This is the most prevalent type and involves lung lining. The Canadian Cancer Society says the median cancer survival for patients with pleural mesothelioma is 12-21 months after diagnosis.

But survival depends on many different things, such as the stage of diagnosis, patient well-being, and the efficacy of treatment for mesothelioma.

Comparison with Peritoneal Mesothelioma: Peritoneal mesothelioma – lining the abdomen – tends to be better prognosticated than pleural mesothelioma.

For peritoneal mesothelioma, the average cancer survival can be 53 months or longer, particularly if surgery and HIPEC are used together. This dichotomy shows the need for modalities and early identification.

Survival Rates by Stage of Mesothelioma: The stage of mesothelioma at diagnosis plays a pivotal role in survival outcomes. Mesothelioma is typically classified into four stages:

• Stage 1: At this early stage, the cancer is localized. The net survival rate for stage 1 pleural mesothelioma patients is around 40% to 50% for one year and 20% to 25% for five years. Early-stage peritoneal mesothelioma patients have even higher survival rates, often exceeding 50% for five years due to effective surgical interventions.
• Stage 2: Cancer has begun to spread but is still relatively localized. The one-year survival rate for stage 2 pleural mesothelioma drops to 30% to 40%, with a five-year survival rate of 10% to 20%. For peritoneal mesothelioma, the five-year survival rate remains higher, typically around 30% to 40%.
• Stage 3: At this advanced stage, cancer has spread to nearby tissues and possibly lymph nodes. The one-year survival rate for stage 3 pleural mesothelioma is approximately 20% to 30%, with a five-year survival rate of 5% to 10%. Peritoneal mesothelioma patients at this stage have a five-year survival rate of about 20% to 30%.
• Stage 4: This is the most advanced stage, with cancer spreading to distant organs. The one-year survival rate for stage 4 pleural mesothelioma is less than 10%, and the five-year survival rate is below 5%. For peritoneal mesothelioma, the five-year survival rate is similarly low, often less than 10%.

Factors Influencing Survival Rates: Several factors influence mesothelioma survival rates, including:

• Age and Overall Health: Younger, healthier patients tend to have better survival rates.
• Gender: Women generally have better survival rates than men.
• Treatment Options: Access to specialized mesothelioma centers and advanced treatments can significantly improve outcomes.
• Genetic Factors: Certain genetic markers can influence how well a patient responds to treatment.

Survival Rates by Treatment Type

Understanding how different treatment types affect mesothelioma survival rates is crucial for patients and their families. Mesothelioma, a cancer linked to asbestos exposure, has various treatment options that can significantly impact survival outcomes.

Mesothelioma Surgery: Surgery is often the first line of treatment for mesothelioma, especially in the early stages. Procedures like pleurectomy/decortication (P/D) and extrapleural pneumonectomy (EPP) aim to remove as much of the tumor as possible.

Studies show that patients undergoing surgery can experience improved overall survival. For instance, the National Cancer Institute reports that patients who undergo EPP may have a median survival of up to 18 months, compared to 12 months for those who do not undergo surgery.

Chemotherapy and Radiation Therapy: Chemotherapy is another cornerstone of mesothelioma treatment. Drugs like pemetrexed and cisplatin are commonly used. According to the American Cancer Society, chemotherapy can extend survival by several months. When combined with surgery, chemotherapy can further improve outcomes.

Radiation therapy is often used to target residual cancer cells post-surgery. While radiation alone may not significantly extend survival, it can reduce mesothelioma symptoms and improve quality of life.

Emerging Immunotherapy Treatments: Immunotherapy is an emerging treatment showing promise in mesothelioma care. Drugs like nivolumab and ipilimumab have been approved for use in mesothelioma. Clinical trials indicate that immunotherapy can improve survival rates, with some patients experiencing extended survival of up to two years or more.

The Mayo Clinic highlights that immunotherapy boosts the body’s immune system to fight cancer cells more effectively.

Multimodal Treatments: Combining multiple treatment types, known as multimodal therapy, often yields the best outcomes. For example, a combination of surgery, chemotherapy, and radiation can significantly improve survival rates.

According to the American Cancer Society, patients receiving multimodal treatments can have a median survival of up to 21 months, compared to 12 months for those receiving only one type of treatment.
 

Improving Mesothelioma Survival Rates

Mesothelioma has historically been associated with poor survival rates. However, recent advancements in early detection, treatment, and supportive care are offering new hope.

This article explores strategies to improve mesothelioma survival rates, emphasizing the importance of early detection, advances in treatment and technology, the role of clinical trials, and the significance of supportive care and lifestyle changes.

Early Detection and Diagnosis: Early detection and diagnosis are crucial in improving mesothelioma survival rates. Mesothelioma often remains undiagnosed until it reaches an advanced stage, making treatment more challenging.

Pleural mesothelioma, which affects the lining of the lungs, and peritoneal mesothelioma, which affects the abdominal lining, are the most common types. Pericardial mesothelioma and testicular mesothelioma are rarer forms. Early detection can significantly enhance the mesothelioma prognosis.

Advanced imaging techniques, such as PET scans and MRI, along with biomarkers like mesothelin, can help identify the disease at an earlier stage. Regular screenings for individuals with known asbestos exposure can lead to earlier diagnosis, allowing for more effective treatment options and better survival outcomes.

Advances in Treatment and Technology: Recent advances in treatment and technology are also improving mesothelioma survival rates. Traditional treatments like surgery, chemotherapy, and radiation therapy are being enhanced with new approaches.

For instance, Moffitt Cancer Center and other leading institutions are pioneering innovative treatments such as immunotherapy and targeted therapy. Immunotherapy harnesses the body’s immune system to fight cancer cells, offering a promising option for mesothelioma patients. Drugs like pembrolizumab and nivolumab have shown effectiveness in clinical trials.

Targeted therapy focuses on specific genetic mutations within cancer cells, providing a more personalized treatment approach. Additionally, cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) has shown significant success in treating peritoneal mesothelioma.

This aggressive treatment approach involves surgically removing visible tumors and then applying heated chemotherapy directly to the abdominal cavity, targeting the remaining cancer cells.

The Role of Clinical Trials: Clinical trials play a vital role in advancing mesothelioma treatment and improving survival rates. These trials test new drugs, therapies, and treatment combinations, providing patients access to cutting-edge treatments that are not yet widely available.

Participation in clinical trials can offer mesothelioma patients additional options when standard treatments are ineffective. Clinical trials also contribute to a better understanding of mesothelioma cell types and how they respond to different treatments.

Supportive Care and Lifestyle Changes: Supportive care and lifestyle changes are essential components in enhancing mesothelioma survival rates. Supportive care focuses on managing symptoms, improving quality of life, and providing emotional and psychological support.

Palliative care teams work alongside mesothelioma specialists to address pain, breathing difficulties, and other symptoms, ensuring patients remain as comfortable as possible. Lifestyle changes, such as maintaining a healthy diet, regular exercise, and quitting smoking, can also positively impact the survival rate for mesothelioma patients.
