Photodynamic therapy

What it is

Photodynamic therapy (PDT) is a cancer treatment that uses light to activate a photosensitizer, which then kills cancer cells through the production of reactive oxygen species. This treatment is used for various types of cancers, including skin, lung, and esophageal cancers.

What research shows

Studies suggest that PDT can be effective in treating certain types of cancer, with some studies showing high response rates and local control. For example, a study on extramammary Paget's disease found that PDT monotherapy was effective in treating localized disease, with a response rate of 100% at one year. However, more research is needed to determine the optimal use of PDT in different cancer types and patient populations.

Current status

PDT is a treatment option that can be used in combination with other therapies to improve outcomes. However, its use is limited by the availability of suitable photosensitizers and the need for precise light delivery. Further research is needed to optimize PDT and make it more accessible to patients.
