Brief Summary

The goal of this diagnostic randomised clinical trial is to determine, in glioblastoma patients with diagnostic uncertainty between pseudoprogression and tumor progression on follow-up MRI after chemoradiation, the added value of a direct \[¹⁸F\] FET-PET scan for clinical management. The main questions it aims to answer are:

  • Does the clinical management guided by an additional FET-PET scan leads to fewer unnecessary interventions, compared with management based on MRI only?
  • Does the clinical management guided by an additional FET-PET scan leads to better health-related quality of life after 12 weeks, compared with management based on MRI only?
  • Does the clinical management guided by an additional FET-PET scan leads to reduced net healthcare costs, compared with management based on MRI only? Researchers will compare the investigational arm, where clinical management is based on the index MRI scan and an additional FET-PET scan, with the control arm, where clinical management is based solely on the index MRI scan, to investigate the added value of the FET PET scan for clinical management. Participants in the investigational arm will undergo the FET PET scan. All participants will complete health-related quality of life questionnaires at four different timepoints.

Outcome Measures

Primary Outcomes (5)

  • Composite score of proportion (0-100%) of patients undergoing unnecessary interventions.

    Determination of 'unnecessary interventions' will be done retrospectively, by the researchers and the treating physician. An 'unnecessary intervention' is defined as: * Biopsy or debulking for diagnostic uncertainty and/or with pseudoprogression as the final pathological diagnosis * The administration of one or more cycles of (temozolomide) chemotherapy as continued treatment for presumed pseudoprogression, in cases with a final diagnosis of tumor progression * The administration of one or more doses of bevacizumab for presumed pseudoprogression, in cases with a final diagnosis of tumor progression

    at six months

  • Health-related quality of life: general

    This will be reported by the questionnaire EQ5D. The EQ5D is a generic utility questionnaire which allows for comparison of quality of life between indications, and is considered the golden standard by the Dutch National Heath Care Institute. Both the total score of the questionnaire is used as the individual scores to analyse individual patients' changes over time.

    at twelve weeks

  • Health-related quality of life: brain tumor specific

    This will be reported by the questionnaire European Organization for Research and Treatment of Cancer Quality of Life Brain Cancer Module (EORTC-QLQ-BN20). The EORTC-QLQ-BN20 is a brain tumor specific questionnaire and is a reliable tool to capture changes in specific health domains for this population. Both the total score of the questionnaire is used as the individual scores to analyse individual patients' changes over time.

    at twelve weeks

  • Health-related quality of life: productivity

    This will be reported by the questionnaire iMTA Productivity Cost Questionnaire (iPCQ). The iPCQ questionnaire measures productivity losses and is applicable to national and international studies. Both the total score of the questionnaire is used as the individual scores to analyse individual patients' changes over time.

    at twelve weeks

  • Health-related quality of life: medical consumption

    This will be reported by the questionnaire iMTA Medical Consumption Questionnaire (iMCQ). The iMCQ questionnaire is an instrument for measuring medical consumption. Both the total score of the questionnaire is used as the individual scores to analyse individual patients' changes over time.

NO INTERVENTION

Interventions

Patients in the investigational arm will undergo the extra FET-PET scan, with use of the O-(2- ¹⁸F-fluoroethyl)-L-tyrosine (¹⁸F-FET) tracer. FET-PET scanning will be performed according to the joint European Association of Nuclear Medicine (EANM)/European Association of Neuro-Oncology (EANO)/Response Assessment in Neuro-oncology (RANO) guidelines. In most patients, a static scan (20-40 minutes post-injection) will performed. If the logistics of the research site allow for a dynamic scan (0-60 minutes post-injection), this will be performed. Interpretation will be done by an experienced nuclear medicine physician from the local center according to current European guidelines. Central review will be performed by a panel of nuclear medicine physicians from the study team. Clinical management is based on the index MRI and this additional \[¹⁸F\] FET PET scan.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with a glioblastoma, IDH-wildtype, World Health Organization (WHO) grade 4, according to WHO 2021 criteria.
  • Age ≥18 years
  • New or increased enhancement within the high-dose radiation field (defined as within the 80% isodose line) on follow-up MRI
  • First moment of clinicoradiological uncertainty regarding the diagnosis (≥3 months after the end of chemoradiation): pseudoprogression or tumor recurrence. The determination of 'uncertainty' is made by the treating physician, preferably in the multidisciplinary tumor board, based on available clinical and standard-of-care MRI-data, which generally includes perfusion-MRI.

You may not qualify if:

  • Previous treatment for recurrence of disease
  • An enhanced lesion size of less than 1 cm on the index MRI. In the newest RANO PET criteria, it is advised to use FET-PET for increasing lesions only in cases with a minimum lesion size.
  • Life expectancy of less than 6 months, determined by the treating physician
  • Contra-indications for PET (claustrophobia, inability to lay still)
  • Women of childbearing potential without adequate contraception
  • Any other concomitant disease that may influence PET imaging or clinical outcomes of this study, this includes but is not limited to: cerebral inflammatory diseases and other cancers with brain- or leptomeningeal metastases
