Metvix PDT Therapy in Oakville, Ontario

What is Metvix Photodynamic Therapy?

Metvix is a prescription cream that is used for treating multiple precancerous lesions and sun damage on the face and/or scalp. At ICLS, we often combine Metvix with Photodynamic Therapy (also known as PDT) to treat a variety of skin conditions, including Actinic Keratosis and Primary Superficial Basal Cell Carcinoma.

Metvix uses light and light-activated medications to pinpoint abnormal cells. The medication is applied topically, allowing it to be absorbed and passed by normal cells. In cancerous cells, however, the medication lasts longer, allowing our specialists to clearly identify areas that require treatment. Natural daylight or red light therapy is used to activate the photosensitizers and release oxygen, effectively treating the problematic cells. The unique formula of Metvix topically penetrates cancerous and precancerous lesions more deeply. Some patients experience significant results only six months following their last treatment.

The main advantage of Metvix therapy is that it offers excellent cosmetic results without the associated scar that can be caused by surgical intervention.

What Conditions Does Photodynamic Therapy Treat?

Photodynamic therapy is beneficial in a wide range of conditions. Some of the conditions it treats include:

• Pancreatic cancer
• Lung cancer
• Esophageal cancer
• Bile duct cancer, sometimes referred to as cholangiocarcinoma
• Head and neck cancers
• Acne
• Psoriasis
• Nonmelanoma skin cancer
• Precancerous skin changes, called actinic keratosis
• Fungal infections
• Viral infections
• Bacterial infections
• Some types of cold sores

In general, it may help with cancerous lesions of various types, including superficial basal cell carcinoma (superficial BCC), squamous cell carcinoma, and others. However, every patient’s situation is different. We encourage you to speak to us about how photodynamic therapy can help you with any type of cancer cells you have been diagnosed with.

How Much Does Metvix Treatment Cost?

A variety of variables determine the cost that you can expect. The type of cancer, the surface of the skin exposed, the type of treatment, and the overall treatment area are some of the factors that impact the cost of this procedure. Keep in mind that when you meet with our health professionals, we will work with you to better understand your needs and offer a clear price after this precise consultation. Photodynamic therapy isn’t covered by Health Canada (OHIP), but your personal work benefits might cover up to 80% or more of the medication cost.

How to Prepare for Metvix Photodynamic Therapy

If you are having photodynamic therapy, your first step will be to speak to our team during a consultation. We will discuss a variety of factors, including the type of cancer cells, the area treated, and your skin needs. We will then offer specific information about how to prepare for your procedure.

Most of the time, this will include:

• Stopping any UV treatments and minimizing any sun exposure to the treatment site for several weeks prior to the treatment.
• Let us know about any type of allergic reactions or complications you have had with health products in the past.
• Discuss any medications you are taking with us during your consultation. We may recommend pausing those medications or making changes based on what our team and your health professionals recommend.

Follow our instructions for preparing the skin prior to your procedure. Do not use any type of skin application prior to your treatment. We also encourage you to minimize any exposure to chemicals, direct sunlight, or creams prior to your treatment.

How Long Does It Take?

Your photodynamic treatment (PDT) will take between 2 and 3 hours to complete. This includes the time it takes to apply the Metvix cream to the area and then allow it to incubate on the treated area. Our goal will be to control any type of reactions you may have, though most people do not. Once the treatment is in place, we expose the treated area to light.

The length of treatment depends on various factors. This includes the treated location (the size and overall location) as well as the protocols we follow. Most people will need two treatments spanned 7 days apart. This will ensure adequate destruction of the lesions.

Aftercare and Recovery

After the treatment is completed, patients may experience some temporary redness and minimal swelling of the skin. Peeling may also be experienced, ranging from very little to copious amounts. Generally, redness should disappear entirely by 2-3 weeks after your treatment, and swelling will reduce or be eliminated after 2-7 days. Patients will require anywhere from 2-3 treatments, depending on Dr. Sapra’s medical team’s recommendations.

Follow-Up and Aftercare

It can take some time for your skin to heal. During this time, we recommend contacting us at any time if you have complications or if the redness does not improve within two to three days. We will also offer pain management and swelling support.

You will need to come in for several treatments. After your sessions, we may recommend additional support, including follow-up care, over the next few weeks and months. Some people may need maintenance treatments over time.

How Many Sessions Are Needed?

Most people need two treatments, some three. PDT is 80 to 90% effective, but some people may need more treatments. Following your procedure, we will evaluate the treatment site to determine what type of additional care you may need on an ongoing basis.

Are Metvix PDT Therapy Results Permanent?

The chemical reaction involved in photodynamic therapy creates a long-lasting result. We call it a semi-permanent solution because it will last several months. Research indicates this treatment can be as successful as other cancer treatments, including chemotherapy and radiation. However, various factors, including the type of cancer, can affect how long the treatment lasts.

What Are the Benefits of Metvix Treatment?

The benefits of photodynamic therapy are numerous and include:

• Less invasive than surgery.
• Treatment can be repeated as necessary.
• Treatment consists of out-of-hospital care.
• Most people with skin lesions see the same or similar results to chemotherapy.

What Are the Side Effects?

Metvix photodynamic therapy is safe for many people to treat cancerous lesions and other skin conditions. However, there are some potential side effects you should know, including:

• Mild swelling at the treatment site
• Scales, crusts, or blister development
• Discoloration of the skin
• Itching, stinging, and burning
• Skin infections

You may have other types of skin and non-skin reactions. Alert your doctor to anything you notice.
