| Japan |
Fifty patients aged 20 years or older with unresectable non-small cell lung cancer scheduled to receive anti-PD-1/PD-L1 inhibitors.
| Chest surgery |
Malignancy
NO
A prospective study to evaluate the utility of FDG-PET/CT and blood-based liquid biopsy as regular monitoring methods for assessing treatment efficacy in anti-PD-1/PD-L1 antibody therapy for non-small cell lung cancer.
Efficacy
FDG-PET/CT: Tumor SUVmax
Blood: Exosome-derived PD-L1 protein
FDG-PET/CT; Metabolic Tumor Volume (MTV), Total Lesion Glycolysis (TLG; SUV mean x MTV), and SUVmax in lymph nodes and metastatic lesions.
Blood; Exosome-derived GLUT1/4, number of blood-derived exosomes
Interventional
Single arm
Non-randomized
Open -no one is blinded
Uncontrolled

Diagnosis
| Medicine |
After obtaining informed consent, FDG-PET/CT will be performed at three time points:
1: Before treatment,
2: One month after treatment initiation,
3: Four months after treatment initiation.
Blood sampling will be conducted before treatment and then monthly until four months after treatment initiation. The PET/CT at time point1 and in cases of recurrence will be covered by insurance, while the PET/CT scans at time points2 and 3 will be considered an intervention, as the radiopharmaceuticals for these scans will be provided by Nihon Medi-Physics Co., Ltd.
The following metabolic-related factors will be measured via PET/CT. The volume of blood drawn per sample in this study is 8 ml.
| 20 | years-old | <= |
| Not applicable |
Male and Female
Non-small cell lung cancer cases in which FDG-PET/CT has been performed before treatment and the tumor proportion score (TPS) has been determined by PD-L1 immunohistochemical staining.
In cases where consent from the patient or their legal representative is not obtained.
