Abstract

Photodynamic therapy has the potential to treat and cure early carcinomas of the head and neck while preserving normal tissue. Thirty patients with neoplasia of the head and neck have been treated with PDT with follow-up to twenty nine months. Four patients with T3 and T4 carcinomas of the upper aerodigestive tract had a partial response. Eleven patients with T1 and T2 carcinomas of the larynx obtained a complete response and are disease free. Seven patients with T1 carcinomas of the tongue, floor of mouth, and nasal cavity obtained a complete response. Three patients with mucosal melanomas of the nasopharynx obtained a complete response and have remained disease free. Two patients with Kaposi's sarcoma of the oral cavity were treated. One obtained a complete response. Three patients with recurrent juvenile laryngotracheal papillomatosis obtained a complete response, but one recurred four months post-PDT. PDT is a promising therapy for treatment of early neoplasia of the head and neck. There are, however, limitations to this treatment based on tumor size and site. Methodology, clinical response, limitations, and complications will be discussed.
