Lung cancer assessed by CT and PET/CT. The patient was diagnosed with lung cancer (35 mm × 30 mm) by computed tomography (CT) and fluorodeoxyglucose (FDG)-positron emission tomography/CT (PET/CT). The tumor size decreased significantly to 12 mm, a 65.7% reduction, after combined therapy with eight doses of WT1/MUC1-DC and erlotinib for 237 days based on CT and FDG uptake by PET/CT. After 321 days of combination therapy, no tumor was detected based on CT. Validation of the tumor’s disappearance persisted for at least 587 days after treatment initiation, without any indication of recurrence or metastasis. Red circles show lung cancer
