abstract = "Background: We evaluated the clinical and immunological effects of dendritic cell (DC) vaccination of patients with NSCLC. Autologous DCs were pulsed with a MAGE containing allogeneic melanoma cell lysate (MelCancerVac{\circledR}, Dandrit Biotech, Copenhagen, Denmark). Imiquimod cream, proleukin and celecoxib were used as adjuvants to the vaccines. The objective of the study was to evaluate specific T cell response in vitro by IFN EliSpot.

Seven patients remained in stable disease (SD) three months after the first vac- cination. After ten vaccinations (six months), four patients still showed SD and continued vaccinations on a monthly basis. These four patients received a total of 12, 16, 26 and 35 vaccinations, respectively. Five patients showed an un- expectedly prolonged survival. The treatment was well tolerated and only minor adverse events were reported. Quality of life did not change during the study period.

Furthermore, we observed an unexpectedly prolonged survival in some patients, which may indicate de-layed effect of DC vaccination after completion of the treatment.
