Summary
Brief summary (as posted)
The hypothesis of this prospective observational pilot study of diagnostic diagnostic performance is that, for patients with NSCLC treated with immunotherapy associated or not with chemotherapy, certain metabolic biomarkers on 18FDG PET scans allow early identification of treatment response (or lack of response to treatment) and optimize prediction of tumor response compared with current standards.

Arms and outcomes
Arms (0)
[]Primary outcomes (1)
- measure
- Metabolic criteria for PET imaging that can distinguish true tumor progression from pseudo-progression of inflammatory origin (leukocyte infiltrate)
- timeFrame
- 36 months
- description
- Calculation of the area of the ROC curve and determination of the optimal threshold of different metabolic parameters extracted from the standard PET image (ΔSUVmax, ΔTLG, appearance of new visceral lesion(s)) and parametric PET image (metabolic glucose rate (Ki), volume of distribution (VD)) to distinguish lesions between true progression from inflammatory pseudoprogressions.
Secondary outcomes (4)
- measure
- Incidence of pseudo-progressions versus true tumor progressions at the first PET scan at 6 weeks.
- timeFrame
- 6 weeks
- description
- Evaluation of the ratio between lesions with pseudo-inflammatory progression and those with true tumor progression (defined a posteriori on control PET-CT). A analysis per lesion and per patient. Two groups of patients will be compared: the group treated with immunotherapy alone and the group treated with a combination of immunotherapy and chemotherapy
