Mesothelioma in Women Living in the USA

Early Diagnosis

Early diagnosis of mesothelioma can improve the chances of survival and reduce the need for aggressive treatment. However, mesothelioma is often hard to diagnose because:

- It has nonspecific symptoms that can mimic other conditions, such as chest pain, shortness of breath, cough, abdominal pain, weight loss, and fatigue

- It can be confused with other types of cancer or benign diseases, such as lung cancer, breast cancer, ovarian cancer, or tuberculosis

- It requires specialized tests and procedures to confirm the diagnosis, such as imaging scans, blood tests, biopsies, and cytology

Therefore, it is important for women to be aware of their risk factors and symptoms of mesothelioma and seek medical help if they suspect they have been exposed to asbestos or have any signs of the disease. Some risk factors for mesothelioma include:

- Occupational exposure: Women who have worked in industries or occupations that used or handled asbestos, such as construction, manufacturing, shipbuilding, insulation, automotive, firefighting, or military

- Environmental exposure: Women who have lived near asbestos mines or factories, or in buildings that contained asbestos materials, such as insulation, tiles, roofing, or pipes

- Secondhand exposure: Women who have been exposed to asbestos fibers carried home by family members or friends who worked with asbestos

- Genetic factors: Women who have a family history of mesothelioma or a genetic mutation that increases the susceptibility to asbestos-related diseases

Surgical Treatment

Surgery is one of the main treatments for mesothelioma. The goal of surgery is to remove as much of the tumor as possible and improve the quality of life. The type of surgery depends on many factors, such as the location and stage of the tumor, the overall health and fitness of the patient, and the availability and expertise of the surgeon. The main types of surgery for mesothelioma are:

- Pleurectomy/decortication: This involves removing the lining of the lung (pleura) and any visible tumor on the lung surface. This surgery preserves the lung function and may be combined with chemotherapy or radiation therapy.

- Extrapleural pneumonectomy: This involves removing the entire lung that has cancer, along with the lining of the lung (pleura), the lining of the heart (pericardium), part of the diaphragm, and nearby lymph nodes. This surgery is more radical and may be done for advanced cases that cannot be treated with pleurectomy/decortication. This surgery may also be combined with chemotherapy or radiation therapy.

- Cytoreduction: This involves removing as much of the tumor as possible from the lining of the abdomen (peritoneum) and any affected organs. This surgery may be done for peritoneal mesothelioma and may be followed by heated intraperitoneal chemotherapy (HIPEC), which involves delivering heated chemotherapy drugs directly into the abdominal cavity.

Surgery can help prolong survival and improve symptoms in some cases of mesothelioma. However, surgery can also cause complications and side effects, such as bleeding, infection, pain, respiratory failure, cardiac arrhythmia, and recurrence.

Chemotherapy

Chemotherapy is the use of drugs to kill cancer cells or stop them from growing. Chemotherapy may be given before surgery to shrink the tumor and make it easier to remove (neoadjuvant chemotherapy), after surgery to reduce the risk of recurrence (adjuvant chemotherapy), or alone or in combination with other treatments for advanced or recurrent cases (palliative chemotherapy).

The most common chemotherapy regimen for mesothelioma is a combination of pemetrexed (Alimta) and cisplatin (Platinol). This regimen has been shown to improve survival and quality of life compared with cisplatin alone. Other chemotherapy drugs that may be used for mesothelioma include carboplatin (Paraplatin), gemcitabine (Gemzar), vinorelbine (Navelbine), and doxorubicin (Adriamycin).

Chemotherapy can help slow down the progression of mesothelioma and relieve symptoms in some cases. However, chemotherapy can also cause side effects, such as nausea, vomiting, hair loss, fatigue, anemia, infection, and nerve damage.

Prognosis

The prognosis of mesothelioma depends on many factors, such as the type and stage of the tumor, the response to treatment, and the overall health and fitness of the patient. In general, the prognosis of mesothelioma is poor, with a median survival of less than 2 years from diagnosis. However, some factors may improve the prognosis of mesothelioma, such as:

- Being female: Women tend to have a better survival rate than men with mesothelioma, possibly because they have less exposure to asbestos, more favorable tumor characteristics, or better response to treatment

- Having epithelioid histology: Epithelioid is the most common type of mesothelioma cells and has a better prognosis than other types, such as sarcomatoid or biphasic

- Having early-stage disease: The earlier the stage of mesothelioma, the better the prognosis. Stage I and II mesothelioma have a median survival of 21 months, while stage III and IV mesothelioma have a median survival of 12 months

- Having multimodal therapy: Multimodal therapy is the combination of two or more treatments, such as surgery, chemotherapy, and radiation therapy. Multimodal therapy can improve survival and quality of life compared with single-modality therapy

Conclusion

Mesothelioma is a rare and aggressive cancer that affects the lining of the lungs, abdomen, or heart. It is caused by exposure to asbestos, a mineral fiber that was widely used in various industries and products until the 1980s. Mesothelioma can take decades to develop after exposure, and it has a poor prognosis, with a median survival of less than 2 years from diagnosis. Mesothelioma is more common in men than in women, but women are also at risk of developing this disease. Early diagnosis of mesothelioma can improve the chances of survival and reduce the need for aggressive treatment. However, mesothelioma is often hard to diagnose because it has nonspecific symptoms that can mimic other conditions. The treatment of mesothelioma depends on many factors and may involve surgery, chemotherapy, radiation therapy, or a combination of these. The treatment of mesothelioma may cause complications and side effects that can be managed with supportive care.
