Overview
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.
Interventions
- Procedure FDG-PET
PET scan are performed within 28 days before the start of immunotherapy, then at week 6 and week 12 of follow-up. Various metabolic parameters extracted from the standard PET image (ΔSUVmax, ΔTLG, appearance of new visceral lesion(s)), parametric (metabolic glucose rate (Ki), volume of distribution (VD)) and tumor response based on PERCIST criteria (adapted to immunotherapy) are assessed.
Primary outcome measures
- Metabolic criteria for PET imaging that can distinguish true tumor progression from pseudo-progression of inflammatory origin (leukocyte infiltrate) [Time frame: 36 months]
Secondary outcome measures (4)
- Incidence of pseudo-progressions versus true tumor progressions at the first PET scan at 6 weeks. [Time frame: 6 weeks]
- Prognostic value of metabolic response PET-CT at 6 weeks and 12 weeks on overall survival at 12, 24 and 36 months [Time frame: 36 months]
- Use of supervised deep-learning algorithms (neural networks) to classify patients as immunotherapy responders or non-responders. [Time frame: 6 months]
- Evaluation of overall survival of patients with oligometastatic progression with maintenance of immunotherapy and targeted irradiation of progressing lesions. [Time frame: 36 months]
