The findings revealed that organ preservation and cancer cure can be achieved in patients with recurrent cancer that is superficially spread in the head and neck, but not deeply infiltrated.

However, the authors cautioned that patients need extensive instruction on how to take the medications and follow-up counseling.

PDT is usually performed as an outpatient procedure, may be repeated, and may be used with other therapies, such as surgery, radiation, or chemotherapy, giving patients a variety of treatment options.

The study was presented at 2009 American Academy of Otolaryngology - Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting and OTO EXPO in San Diego.
