Brief Summary:
The hypothesis of this diagnostic performance study is that, for patients treated for immunotherapy-treated melanoma or NSCLC, some metabolic parameters of the 18FDG dual-point PET scan distinguish inflammatory pseudo-progression from tumor progression true and thus improve the evaluation of tumor response to immunotherapy

Condition or disease Intervention/treatment Phase
Non-Small Cell Bronchopulmonary Carcinoma or Melanoma Radiation: 18FDG PET Not Applicable

Detailed Description:

The originality of this study is based on the stakes of the early prediction of resistance to immunotherapy (early therapeutic escapes, side effects, cost of treatment etc.).

No prospective study has been published to date on the value of 18FDG PET to distinguish between true tumor progression and pseudo-progression. Studies are therefore needed to define new criteria for evaluating the metabolic response specific to immunotherapy, as well as the optimal timing of the interim examination.

The goal is to conduct a transversal, non-randomized, prospective, multi-center, diagnostic performance study, harmonizing the moments of the 18FDG PET scans, acquisition conditions and interpretation criteria. The use of a dual-point acquisition in PET will also make it possible to judge the kinetics of 18FDG lesion capture (calculation of the 18FDG retention index on the late image) with the objective of highlighting PET criteria to distinguish between inflammatory pseudo-progression and true tumor progression in patients with unresectable melanoma or advanced or metastatic NSCLC. Other metabolic parameters will be studied, such as changes in tumor metabolic volume and binding intensities.

Finally, this study will include patients to assess the correlation between the metabolic tumor response observed after 7 weeks of immunotherapy, the morphological response after 3 months of treatment (RECIST v1.1 and i-RECIST) and survival overall at 1 year.

Primary Outcome Measures :
  1. Threshold of the 18FDG retention index (dual-point acquisition), from the first metabolic progression observed in 18FDG PET, to distinguish a true tumor progression from a pseudo-progression of inflammatory origin (leukocyte infiltrate) [ Time Frame: 12 months ]
    ROC curve of the FDG retention index, defined on the dual-point PET acquisition, will be analysed to distinguish lesions in true progressions and lesions in inflammatory pseudo-progressions.


Secondary Outcome Measures :
  1. PET criteria other than the 18FDG retention index to distinguish pseudo-progressions from true tumor progressions for new lesions: intensity of fixation (SUVpeak) and location of new lesions [ Time Frame: 12 months ]
    It will be measured with absolute SUVpeak of new hyperfixing lesions

  2. PET criteria other than the 18FDG retention index to distinguish pseudo-progressions from true tumor progressions for new lesions: intensity of fixation (SUVpeak) and location of new lesions [ Time Frame: 12 months ]
    It will be measured with Percent change in fixation intensity of pre-existing lesions

  3. PET criteria other than the 18FDG retention index to distinguish pseudo-progressions from true tumor progressions for new lesions: intensity of fixation (SUVpeak) and location of new lesions [ Time Frame: 12 months ]
    It will be measured with Percentage of change in lesional tumor volume

  4. PET criteria other than the 18FDG retention index to distinguish pseudo-progressions from true tumor progressions for new lesions: intensity of fixation (SUVpeak) and location of new lesions [ Time Frame: 12 months ]
    It will be measured with Percentage of change in total Total Lesion

  5. The incidence of inflammatory pseudo-progression compared to true tumor progressions, taking into account the impact of the primary tumor [ Time Frame: 12 months ]
    Evaluation of the ratio between the lesions with an inflammatory pseudo-progression and those with a true tumor progression will be measured. A lesion and patient analysis will be performed

  6. The incidence of inflammatory or infectious lesions diagnosed by 18FDG PET and their impact on clinical management [ Time Frame: 12 months ]
    Frequency of inflammatory or infectious lesions accidentally diagnosed by PET will be measured

  7. The incidence of inflammatory or infectious lesions diagnosed by 18FDG PET and their impact on clinical management [ Time Frame: 12 months ]
    The number of these inflammatory diagnoses leading to specific management will be measured

  8. The predictive value of the early metabolic response at 7 weeks on the morphological [ Time Frame: 3 months ]
    Measurement of the association will be assessed with the early metabolic response at 7 weeks . The metabolic response will be evaluated according to PERCIST criteria.

  9. The predictive value of the early metabolic response on metabolic responses at 3 months [ Time Frame: 3 months ]
    Measurement of the association will be assessed with the morphological response at 3 months. The morphological response will be evaluated according to RECIST criteria v1.1 and i-RECIST in patients who have received the injection of iodine contrast product in PET scan

  10. The prognostic value of the 7-week PET metabolic response on 12-month overall survival [ Time Frame: 12 months ]
    To determine the delay between the date of inclusion and the date of death, overall survival will be measured at 12 months according to the changes in tumor metabolism on the interim PET at 7 weeks.

  11. The prognostic value of the 3-month PET metabolic response on 12-month overall survival [ Time Frame: 12 months ]
    To determine the delay between the date of inclusion and the date of death, overall survival will be measured at 12 months according to the changes in tumor metabolism on the interim PET at 3 months.
