Pulmonary resection after successful downstaging with photodynamic therapy.

Photodynamic therapy (PDT) is a treatment option for lung cancer that involves the administration of a photosensitizing agent and selective, bronchoscopic delivery of light to tumor tissue that has retained the agent. Currently, PDT is used either to treat microinvasive endobronchial nonsmall cell lung cancer (NSCLC) or to palliate patients with completely or partially obstructing endobronchial NSCLC. Herein is a case of PDT that successfully downstaged an obstructing endobronchial NSCLC, thereby enabling a complete resection. At 9 months postoperatively, the patient was treated for a chest wall recurrence with no evidence of disease in the airway or mediastinum.
