Analysis of the Cost‐effectiveness of PhotodynamicTherapy in Early Stage Lung Cancer

Abstract
Methods A cost-effectiveness analysis was carried out for photodynamic therapy (PDT) performed in early stage lung cancer cases, which by definition have no lymph node metastasis. The alternative treatment method was lobectomy, which conventionally would have been the first choice of treatment. Costs (C) and effectiveness (E) both of the PDT group and operation group were compared. Effectiveness was determined using quality adjusted life years saved (QALYs) which is the 5-year survival rate adjusted in terms of the quality of life of the patient, and the cost-effectiveness rate was obtained based on the costs of treatment methods during the patient's stay in the hospital. Health care costs, including drugs, were calculated according to the 1992 National Health Insurance list in yen. Costs which were non-reimbursable by the public insurance system, such as for special rooms and sun block cream, were also expressed in yen.
