The use of photodynamic therapy using 630 nm laser light and porfimer sodium for the treatment of oral squamous cell carcinoma

PDT has been demonstrated in clinical studies to be an efficacious method for the treatment of dysplastic, microinvasive and early forms of cancer. The advantage of PDT for early carcinomas of the oral cavity is the ability to preserve normal tissues while effectively treating cancers up to 1cm in depth. The case presented here successfully demonstrates the ability to use PDT to treat maxillary gingival squamous cell carcinoma thereby sparing the use of surgery or radiation therapy at this point in the management of the disease.
