Photodynamic Therapy (PDT) for the Treatment of Actinic Keratoses

DESCRIPTION

Actinic keratoses (AKs) are the most common pre-malignant skin lesions.  They are found predominantly on the scalp, face, dorsal hands and lower extremities.  Typically caused by solar photodamage, actinic keratoses appear as rough, scaly patches ranging in normal skin tone to reddish brown.  

Actinic keratoses are common precursors to squamous cell carcinoma (SCC) and basal cell carcinoma (BCC), which are collectively known as keratinocyte carcinoma (KC), the most common malignancy in the United States.  Up to forty-four percent of potentially fatal metastatic squamous cell carcinomas originate from actinic keratoses.

Differential diagnosis of actinic keratoses as opposed to early SCC in-situ or Bowen’s disease is difficult as there are no sharp histological criteria that precisely define their limits.  Some authorities consider them to be the same condition, a clinically significant implication, as poorly differentiated squamous cell carcinoma is the most likely to recur as invasive disease and metastasize.  This indicates that actinic keratoses should receive prompt treatment:  There is no way to determine which lesions will progress into invasive or metastatic carcinoma and removal of early lesions is relatively simple

Photodynamic therapy is a method of treating actinic keratoses which involves the application of an agent to each lesion where it is converted into photosensitive protoporphyrin.  Upon exposure to a light source of a specific wave length, photoactivation causes the production of toxic singlet oxygen and other cytotoxic free radicals which lead to cell death and destruction of the lesion.  

Examples of photodynamic therapy for the treatment of actinic keratoses (AKs) are aminolevulinic acid (e.g., Levulan® Kerastick®) used with a blue light source (e.g., Blu-U® Blue Light Photodynamic Therapy Illuminator) and methyl aminolevulinate hydrochloride (e.g., Metvixia®) used with an LED based narrow band (630 nm) red light technology device (e.g., Aktilite® CL128).

MEDICAL APPROPRIATENESS

APPLICABLE TENNESSEE STATE MANDATE REQUIREMENTS

Tennessee State law requires coverage of off-label indications of Food and Drug Administration (FDA) approved drugs when the off-label use is relative to life-threatening illnesses, such as cancer, AIDS, and coronary heart disease and recognized in one of the standard reference compendia (As defined in the statute:  The United States Pharmacopoeia Drug Information, The American Medical Association Drug Evaluations, & The American Hospital Formulary Service Drug Information) or in the medical literature. This law is applicable to all fully insured members. The law is not applicable to self-funded accounts, but coverage for off-label uses may be provided based on the contractual agreement.  

ADDITIONAL INFORMATION  

For appropriate dosage information, contraindications, precautions, warnings, and monitoring information, please refer to one of the standard reference compendia (e.g., The American Hospital Formulary Service Drug Information).

No controlled studies were found in the published literature that validate the application of photodynamic therapy (PDT) for the treatment of other dermatologic conditions including, but not limited to squamous cell carcinoma, basal cell carcinoma or Bowen's disease.
