Introduction
Mesothelioma is a rare and aggressive form of cancer that primarily affects the lining of the lungs, abdomen, or heart. It is caused by exposure to asbestos, a mineral commonly used in construction and other industries until the 1970s. Unfortunately, mesothelioma has a poor prognosis and is often diagnosed at an advanced stage when treatment options are limited. However, recent developments in cancer research have led to promising new therapies, including the use of Avastin.
In this article, we will explore the benefits of using Avastin for mesothelioma patients, how it works, and its potential side effects. We will also answer some common questions about Avastin and provide a comprehensive guide on this innovative treatment option.
What is Avastin?
Avastin is a monoclonal antibody that targets a protein called vascular endothelial growth factor (VEGF). This protein is responsible for the formation of blood vessels that supply nutrients and oxygen to tumors, allowing them to grow and spread. By blocking VEGF, Avastin inhibits the growth of new blood vessels and reduces the blood supply to cancerous cells. This slows down the progression of the disease and may improve the effectiveness of other cancer treatments.
How does Avastin work?
Avastin works by attaching to VEGF and preventing it from binding to its receptors on the surface of blood vessels. This prevents the growth of new blood vessels and reduces the supply of nutrients and oxygen to cancer cells. Additionally, Avastin may enhance the immune response against cancer cells and help to promote cell death (apoptosis).
How is Avastin administered?
Avastin is given as an infusion (intravenous injection) over a period of 30-90 minutes. The dosage and frequency of Avastin depends on the patient’s weight, medical history, and response to treatment. Avastin is typically administered in a hospital or medical clinic under the supervision of a trained healthcare provider.
What are the potential side effects of Avastin?
Like all medications, Avastin may cause side effects in some patients. The most common side effects of Avastin include fatigue, headache, high blood pressure, decreased appetite, nausea, vomiting, and diarrhea. More serious side effects may include bleeding, blood clots, heart attack, stroke, and perforation of the intestines. Patients should discuss the potential benefits and risks of Avastin with their healthcare provider before starting treatment.
Is Avastin approved for mesothelioma treatment?
Avastin is not specifically approved by the US Food and Drug Administration (FDA) for the treatment of mesothelioma. However, it is approved for the treatment of other types of cancer, such as lung, brain, and colorectal cancer. Some oncologists may use Avastin in combination with chemotherapy as a standard of care for mesothelioma patients.
How Effective is Avastin for Mesothelioma?
The effectiveness of Avastin for mesothelioma is still under investigation, but early studies show promising results. A phase II clinical trial conducted by the Mesothelioma Applied Research Foundation found that patients who received Avastin in combination with chemotherapy had a median overall survival of 18.8 months, compared to 16.1 months for those who received chemotherapy alone. Another study published in the Journal of Thoracic Oncology showed that Avastin in combination with chemotherapy improved progression-free survival and overall response rates in mesothelioma patients.
Who is a candidate for Avastin treatment?
Avastin may be recommended for mesothelioma patients who have not responded to standard chemotherapy or who have relapsed after previous treatment. However, not all patients are eligible for Avastin treatment, as it may worsen certain medical conditions, such as uncontrolled high blood pressure or bleeding disorders. It is important to discuss your individual case with your healthcare provider to determine if Avastin is a viable option for you.
How long does Avastin treatment last?
The duration of Avastin treatment depends on the patient’s response to therapy and overall health status. In some cases, Avastin may be given as a maintenance therapy to prevent cancer recurrence or progression. Your healthcare provider will monitor your progress and determine the appropriate duration of treatment.
How much does Avastin cost?
The cost of Avastin can vary widely depending on the dosage, frequency of treatment, and location. According to GoodRx, the average cost of a single dose of Avastin is around $2,500, but it may range from $1,600 to $5,200. However, many insurance plans may cover the cost of Avastin for medically necessary treatments. Patients should consult with their insurance providers to determine coverage options.
