Photodynamic Therapy

What is photodynamic therapy?

Photodynamic therapy (PDT) is a medical treatment that uses a photosensitizing drug (a drug that becomes activated by light exposure) and a light source to activate the applied drug. The result is an activated oxygen molecule that can destroy nearby cells. Precancerous cells and certain types of cancer cells can be treated this way. The procedure is easily performed in a physician's office or outpatient setting.

PDT essentially has three steps. First, a light-sensitizing liquid, cream, or intravenous drug (photosensitizer) is applied or administered. Second, there is an incubation period of minutes to days. Finally, the target tissue is then exposed to a specific wavelength of light that then activates the photosensitizing medication.

Steps:

  1. application of photosensitizer drug
  2. incubation period
  3. light activation

Although first used in the early 1900s, PDT in the modern sense is a fairly new, evolving science. Current PDT involves a variety of incubation times for the light-sensitizing drug and a variety of light sources depending on the target tissue. The basic premise of PDT is selective tissue destruction. Although the photosensitizer may be absorbed all over by many cells, atypical or cancerous cells take up more of the drug and retain the drug for a longer duration than normal tissues.

At present, the primary limitation of available PDT techniques is the depth of penetration of the light and ability to target cells within at most 1/3 of an inch (approximately 1 cm) of the light source. Therefore, tumors or atypical growths must be close to the surface of the skin or treatment surface for PDT to work.

PDT is currently used in a number of medical fields including oncology (cancer), dermatology (skin), and cosmetic surgery.

In oncology, it is FDA approved for non-small cell lung cancer, esoph...

Actinic Keratosis »

What is an actinic keratosis, and what does it look like?

An actinic keratosis (AK), also known as a solar keratosis, is a small, rough spot occurring on skin that has been chronically exposed to the sun. Actinic keratoses generally measure in size between 2-6 millimeters in diameter (between the size of a pencil point and that of an eraser). They are usually reddish in color, with a rough texture and often have a white or yellowish scale on top. Actinic keratosis often occurs against a background of sun damage, including sallowness, wrinkles, and superficial blood vessels.

In addition to feeling rough, actinic keratoses may feel sore or painful when fingers or clothing rub against them.

Specialized forms of actinic keratoses include cutaneous horns, in which the skin protrudes in a thick, hornlike manner, and actinic cheilitis, which refers to scaling and roughness of the lower lip and blurring of the border of the lip and adjacent ski...
