Malignant Peritoneal Mesothelioma: A Review

🔬 Understanding the Rare Cancer

Greetings to all readers! Malignant peritoneal mesothelioma (MPM) is a rare cancer affecting the lining of the abdominal cavity, with only approximately 500 new cases diagnosed each year in the United States. It is caused by exposure to asbestos and has a poor prognosis, with an average survival rate of approximately one year.

In this article, we will provide an in-depth review of MPM, including its causes, symptoms, diagnosis, treatment, and prognosis. We will also provide answers to frequently asked questions about the disease and offer some practical tips for those affected by it.

📚 Causes and Risk Factors

As mentioned, exposure to asbestos is the primary cause of MPM. Asbestos is a naturally occurring mineral fiber that was used in various industries, including construction, shipbuilding, and automotive manufacturing, until the 1970s due to its heat-resistant and insulating properties. When inhaled or ingested, asbestos fibers can become lodged in the lining of the lungs, heart, or abdomen, leading to inflammation and scarring that may eventually develop into cancer.

Other risk factors for MPM include genetics, radiation therapy to the abdomen, and a weakened immune system. However, these factors are less significant than asbestos exposure in causing the disease.

🔎 Symptoms and Diagnosis

The symptoms of MPM can be vague and nonspecific, making it challenging to diagnose in its early stages. Common symptoms include abdominal pain and swelling, bloating, nausea and vomiting, weight loss, and fatigue. These symptoms may be mistaken for other gastrointestinal disorders such as irritable bowel syndrome or ovarian cancer.

Diagnosis of MPM usually involves several tests, including imaging studies, blood tests, and a biopsy of the affected tissue. Imaging studies such as X-rays, CT scans, and MRI scans can detect abnormalities in the abdomen, such as fluid buildup and thickening of the peritoneum. Blood tests may show elevated levels of certain proteins associated with MPM. A biopsy is the most definitive method of diagnosing MPM, where a sample of the affected tissue is taken and examined under a microscope for the presence of cancer cells.

🔬 Treatment and Prognosis

The treatment of MPM depends on several factors, including the stage of the disease, the patient’s overall health, and the extent of asbestos exposure. Surgery, chemotherapy, and radiation therapy are the most common treatments used for MPM, either alone or in combination.

Despite the advances made in treatment over the years, the prognosis for MPM remains poor. The average survival rate for patients with MPM is approximately one year, although some patients may survive for several years with aggressive treatment.

❓ Frequently Asked Questions

1. What is the difference between mesothelioma and MPM?

Mesothelioma is a type of cancer that affects the lining of the lungs, heart, or abdomen, while MPM specifically affects the lining of the abdomen.

2. Is MPM curable?

Currently, there is no known cure for MPM, but treatment can help manage symptoms and prolong survival.

3. How long does it take for MPM to develop after asbestos exposure?

The latency period between asbestos exposure and the development of MPM can range from 20 to 50 years.

4. How is MPM different from ovarian cancer?

The symptoms of MPM and ovarian cancer can be similar, but MPM specifically affects the lining of the abdomen, while ovarian cancer starts in the ovaries.

5. Can MPM be prevented?

The best way to prevent MPM is to avoid exposure to asbestos, which can be achieved by wearing protective equipment and following safe work practices in industries where asbestos is present.

6. Is MPM hereditary?

Although genetics may play a role in the development of MPM, it is not typically considered an inherited disease.

7. How is MPM staged?

MPM is staged based on the extent of the cancer’s spread, with Stage 1 being the earliest stage and Stage 4 being the most advanced.

8. What is the goal of MPM treatment?

The goal of MPM treatment is to manage symptoms, improve quality of life, and prolong survival.

9. Can MPM spread to other parts of the body?

Yes, MPM can spread to other parts of the body, including the lungs, liver, and bones.

10. What is the survival rate for MPM?

The average survival rate for MPM is approximately one year, although some patients may survive for several years with aggressive treatment.

11. How is MPM treated with chemotherapy?

Chemotherapy drugs are typically administered intravenously and target fast-growing cancer cells. Chemotherapy may be used alone or in combination with other treatments like surgery and radiation therapy.

12. What are the side effects of MPM treatment?

The side effects of MPM treatment can include nausea, vomiting, fatigue, hair loss, and decreased appetite.

13. Are there any clinical trials for MPM?

Yes, there are ongoing clinical trials for MPM that are testing new treatments and therapies. Patients with MPM may be eligible to participate in these trials.
