[Application and progress of photodynamic therapy in combination therapy of lung cancer].

Abstract

Lung cancer is one of the most common malignant tumors with high morbidity and mortality. At present, the traditional treatments of lung cancer include surgical resection, radiotherapy, chemotherapy, targeted therapy and immunological therapy. The modern model of diagnosis and treatment tends to be multidisciplinary, individual, focusing on systemic therapy combined with local therapy. Recently, PDT(photodynamic therapy) becomes an emerging cancer treatment due to its advantages of low trauma, high selectivity, hypotoxicity, good reutilization. PDT has a good effect in the radical treatment of early airway cancer and palliative treatment of advanced airway tumor by using its photochemical reactions. Nevertheless, more attention is focused on combination therapy of PDT Combination with surgery can reduce tumor burden and eliminate potential lesions; Combination with radiotherapy can reduce the amount of radiation and improve therapeutic effect; Combination with chemotherapy achieves the combination of local and systemic therapy; Combination with targeted therapy can enhance anti-cancer targeting; combination with immunotherapy can improve anti-cancer immunity, etc. This article focused on PDT as a part of a combination therapy in the treatment of lung cancer, to provide a new treatment method for patients with poor therapeutic effect with traditional treatment.
