Introduction
Mesothelioma is a rare and aggressive form of cancer that affects the lining of the lungs, abdomen or heart. It is caused by long-term exposure to asbestos, a naturally occurring mineral that was widely used in the construction industry. Photodynamic therapy is a promising treatment option for mesothelioma patients at the University of Virginia.
Photodynamic therapy (PDT) is a minimally invasive procedure that uses a combination of light and a special type of medication called a photosensitizer to destroy cancer cells. The photosensitizer is injected into the bloodstream and absorbed by cancer cells. When exposed to a specific type of light, the photosensitizer produces a toxic form of oxygen that kills cancer cells.
PDT has several advantages over other mesothelioma treatments, such as surgery, chemotherapy and radiation therapy. It is less invasive, does not cause as many side effects, and can be repeated several times if necessary. PDT can also be used in combination with other treatments to improve outcomes.
At the University of Virginia, we have a team of experienced doctors, nurses and researchers who are dedicated to developing new and innovative treatments for mesothelioma. Our PDT program is led by Dr. James Welsh, a world-renowned expert in the field of photodynamic therapy.
In this article, we will discuss the benefits of photodynamic therapy for mesothelioma patients at the University of Virginia, how it works, and what to expect during and after the procedure.
Photodynamic Therapy for Mesothelioma
Photodynamic therapy is a relatively new treatment for mesothelioma, but it has shown promising results in clinical trials. The procedure involves three main steps:
| Step 1 | The patient is injected with a photosensitizer, which is absorbed by cancer cells. |
|---|---|
| Step 2 | The photosensitizer is activated by a specific wavelength of light, which causes it to produce a toxic form of oxygen that kills cancer cells. |
| Step 3 | The damaged cancer cells are then cleared away by the body’s immune system, which helps prevent the cancer from spreading. |
PDT is typically performed on an outpatient basis, which means that patients can go home the same day as the procedure. The treatment itself takes about 30 minutes to an hour, but patients need to avoid exposure to sunlight for several days afterwards.
Who Is Eligible for PDT?
PDT is most effective for mesothelioma patients who have early-stage or localized disease. It can be used as a primary treatment or in combination with other treatments, such as surgery, chemotherapy or radiation therapy.
Not all mesothelioma patients are eligible for PDT, however. Patients who have advanced disease or who have certain medical conditions, such as porphyria, should not undergo the procedure.
Benefits of PDT
There are several benefits to undergoing photodynamic therapy for mesothelioma:
- Less invasive than surgery
- Does not cause as many side effects as chemotherapy or radiation therapy
- Can be repeated several times if necessary
- Can be used in combination with other treatments to improve outcomes
- Targets cancer cells while sparing healthy tissue
PDT also has a high success rate in treating early-stage mesothelioma, with some studies reporting a five-year survival rate of up to 40 percent.
Side Effects of PDT
Like any medical procedure, photodynamic therapy can cause some side effects. The most common side effects include:
- Temporary sensitivity to sunlight
- Redness and swelling at the treatment site
- Coughing or shortness of breath
- Nausea and vomiting
- Low blood pressure
Most side effects are temporary and go away on their own within a few days to weeks. Patients should follow their doctor’s instructions carefully and report any side effects immediately.
What to Expect During PDT
Before undergoing photodynamic therapy, patients will need to have a consultation with their doctor to determine if they are eligible for the procedure. During the consultation, the doctor will explain the risks and benefits of PDT and answer any questions the patient may have.
The actual PDT procedure typically takes place in a hospital or outpatient clinic. Patients will need to arrive several hours before the procedure to have the photosensitizer injected and to allow it to be absorbed by cancer cells.
Once the photosensitizer has been absorbed, the patient will be exposed to a specific wavelength of light for a set amount of time. The light may be delivered through a special light-emitting device or through fiber optic cables.
After the procedure is complete, patients will need to avoid exposure to sunlight for several days. They may experience some side effects, such as sensitivity to sunlight, redness and swelling at the treatment site, and coughing or shortness of breath. These side effects typically go away on their own within a few days to weeks.
Research on PDT
The University of Virginia is actively involved in research on photodynamic therapy for mesothelioma. Our research is focused on improving the effectiveness of PDT and developing new photosensitizers that can be used in combination with other treatments.
One recent study conducted at the University of Virginia found that PDT combined with surgery and chemotherapy resulted in a longer overall survival time for mesothelioma patients compared to surgery alone. This suggests that PDT may be a valuable addition to standard mesothelioma treatments.
