Overview. Photodynamic therapy (PDT) is a type of treatment that uses light along with chemicals known as photosensitizers to treat cancer and other conditions. Photosensitizers can kill nearby cells when they come into contact with certain wavelengths of light. This is because the light causes the photosensitizer to create an oxygen that’s toxic ...

Why do we use PDT?
Purpose. PDT is used to treat a variety of cancer types. Skin cancer is the most common type of cancer typically treated using PDT techniques. This is because the skin can easily be exposed to light. In this type of PDT, a photosensitizer is applied to your skin around the cancerous area and then exposed to a certain light wavelengths.

Where was PDT discovered?
PDT was discovered more than a century ago in Munich, Germany, when a medical student noticed that microorganisms that had been colored with different compounds died when they were exposed to light . Inspired by that discovery, researchers tried, but failed, to find ways of using light-sensitive compounds to treat cancer, smallpox, tuberculosis and other diseases.
What is PDT therapy?
PDT is also referred to as blue light therapy. PDT essentially has three steps. First, a light-sensitizing liquid, cream, or intravenous drug (photosensitizer) is applied or administered. Occasionally, a photosensitizing molecule that is already part of the body can be activated.

What is the basic premise of PDT?
The basic premise of PDT is selective tissue destruction. At present, the primary limitation of available PDT technology for skin is the depth of penetration of the light and ability to target cells within 1/3 of an inch (approximately 1 cm) of the light source.
When was PDT first used?
Although first used in the early 1900s, PDT in the modern sense is a new, evolving science. Current PDT involves a variety of incubation times for different the light-sensitizing drugs and a variety of light sources depending on the target tissue. The basic premise of PDT is selective tissue destruction.

What is PDT treatment?
Photodynamic Therapy (PDT) is a treatment that originated in the early 1980s and has been growing in popularity recently for various conditions like acne, psoriasis or acute macular degeneration. Initially used in cancer for the treatment of skin cancers (and rapidly extended for cancers of the prostate and the respiratory system), it is based on the combined action of three harmless components when taken separately: oxygen, photosensitive agents and light.

Why is photodynamic therapy limited?
Challenges of photodynamic therapy. Phototherapy has a limited use for the moment due to the accessibility of light to the area to be treated. Deep or extensive cancers cannot be treated at the moment.
What is the first photodynamic therapy for cancer?
The fist photodynamic therapy approved for cancer was Porfimer Sodium, in 1993 for bladder cancer. Since then, it has been extended to other cancers like esophageal cancer and non-small cell lung cancer and is still studied for continued expansion. A second generation emerged, like Aminolevulinic acid for pre-cancerous skin diseases, and many chlorin based PS like Temoporfin or Talaporfin for various types of cancers (exclusively for skin or luminal organs) have been approved.
How many people died from cancer in 2018?

Where are photosensitive agents introduced?
Photosensitive agents are introduced at the site of the tumor, in the form of a cream for skin cancers or intravenously near the tumor for other cancers.

Recovering from SPDT can take as little as a day to a few weeks, depending on the cancer location and the intensity of the treatment.
How long does it take for cancer cells to absorb sensitizer?
Cancer cells absorb the sensitizer while healthy cells reject it. This could take a few hours or a few days, depending on the mode of administration and the sensitizer dose. Light and sound are applied, which causes the cancer cells to react and form an oxygen molecule that kills the cells.
Does SPDT work with hyperthermia?
SPDT may enhance the effect of other therapies. Sono-photo dynamic therapy can work with: Hyperthermia. Intravenous botanicals, such as vitamin C. Chemotherapy, especially in breast cancer patients. Detoxification treatments, which help remove the buildup of toxins in the body during cancer treatment (especially from the breakdown of cancer cells)
Can you get cured from SPDT?
SPDT also destroys the blood vessels that feed cancer cells. Patients are generally are not “cured” with one treatment. Depending on your type and stage of cancer, you may need repeated treatments. In some cases, the therapy can be done at home over a period of time.
