About this study

This is a single-centre observational study. Patients with proven locally advanced NSCLC will be treated with concurrent chemoradiotherapy according to the standard clinical protocol of the NKI-AVL. During treatment, the biological behaviour of the tumour will be monitored with serial quantitative FDG (fluorodeoxyglucose) PET/CT scans. From these images, the time during treatment where a 50% reduction in FDG uptake relative to day 1 is reached (T50) will be derived. The T50 of progression-free surviving patients will be compared with that of relapsed or deceased patients, in order to find a value that predicts early treatment failure. An additional FDG PET/CT scan at the same day as regular follow up CT scan will be made, two months after treatment, to have a baseline after treatment for follow up.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Cytologically or histologically proven NSCLC
  • T2-4 N0-3 M0 disease (stage II or III, inoperable)
  • Scheduled for standard concurrent chemoradiation
  • Primary tumour minimal diameter 3 cm
  • Primary tumour SUVmax > 5 on routine diagnostic pre-treatment FDG (Fludeoxyglucose) PET/CT
  • WHO performance 0-1
  • Written informed consent according to GCP (Good Clinical Practice) and national regulations

Exclusion criteria

  • Age < 18 years, incapacitated subjects
  • Pregnant or lactating women
  • Diabetes mellitus requiring medication
  • Participation in dose escalation studies
  • Other neoplasms in the last 3 years, with metastases

Treatment and study plan

Low dose FDG PET/CT 5 x.

Other

Multiple FDG PET/CT studies will be added to the normal diagnostic procedures as a part of this study, with the number of scans depending on the study stage, to a maximum of 6 per patient.

Other names: No treatment intervention but diagnostic intervention.

Primary outcomes

  1. maximum FDG uptake (SUVmax)

    Time frame: 1 Year

    • A main study parameter is the maximum FDG uptake (SUVmax (maximum Standardized Uptake Value)) at the location of the primary tumour, as determined at multiple days during treatment (with a maximum of five time points per patient), expressed as T50 for response evaluation.

Secondary outcomes

  1. SUVmax during the first two weeks of treatment, indicating inflammatory response.

    Time frame: First Two weeks of treatment

    • Increase SUVmax during the first two weeks of treatment, indicating inflammatory response.

  2. SUVmax in the two weeks prior to treatment, indicating progression

    Time frame: Two weeks prior to treatment

    • Increase SUVmax between diagnostic imaging and start of treatment, indicating potential progression.

  3. Progression free survival

    Time frame: 1 Year

    • Secondary study endpoint is progression free survival, to be associated with T50 for prognostic value.
