Radiotherapy in IDH Mutated Glioma: Evaluation of Late Outcomes

The Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 displays Grade 1 to 5, ranging from 'mild' to 'death'. The case report form will include a predefined set of CTCAE items of expected radiotherapy related toxicities. In addition, other CTCAE toxicities grade ≥ 2 that are likely, possibly or definitely related to the radiotherapy should be recorded in the case report form (CRF), when they occur. All items will include a causality assessment: likely or definitely attributable to radiotherapy, unrelated or unlikely attributable to radiotherapy, or not assessable.

Neurocognitive functioning will be assessed with a standard and well established short neuropsychological test battery, developed for use in clinical trials. The following tests are included: Hopkins Verbal Learning Test (HVLT), Trail Making Test part A and B (TMT A/B), Controlled Oral Word Association (COWA), Medical Outcomes Study Cognitive Functioning Scale (MOS), Diagnostic Instrument for Mild Aphasia (DIMA)

NIFS is defined as time from first irradiation to date of initiation of further treatment after radio- and/or chemotherapy or death (any cause), whichever occurs first.

PFS is defined as the time from first irradiation to progressive disease, according to (any of) the Response Asessment in Neuro Oncology (RANO) criteria for progressive disease in low grade glioma.

OS is defined as time from first irradiation to date of death from any cause.

HRQoL will be assessed with the EORTC quality of life questionnaire (QLQ-C30) supplemented by the neuro-oncological module (QLQ-BN20) and the Euro Quality of Life questionnaire (EQ5D-5L)

For the Health Related Economics (HR-E) analyses, the EQ5D - 5L questionnaire will be used in conjunction with the Productivity Costs Questionnaire (iPCQ) and the Medical Consumption Questionnaire (iMCQ). These questionaires are optional.

If feasible, pre- and 4 months post-treatment a scan protocol will be used that, besides the standard clinical imaging, will focus on (micro-)structural and microvascular characteristics that could predict neurocognitive outcome and treatment efficacy. This feasibility is site-specific.

Radiotherapy and concurrent chemotherapy plus adjuvant temozolomide chemotherapy

Brain and Central Nervous System Tumors

Patients randomized to concomitant temozolomide will receive temozolomide continuously at a daily dose of 75 mg/m² during radiotherapy.

temozolomide

MGMT methylation status is used for stratification at randomization.

DNA methylation analysis

laboratory biomarker analysis

Patients randomized to adjuvant temozolomide will start adjuvant temozolomide after a 4 week resting period after the end of radiotherapy.

adjuvant therapy

Quality of Life analysis will also be used to assess neurological deterioration free progression

quality-of-life assessment

Radiotherapy will consist of a conventionally fractionated regimen for 6.5 weeks in a once daily schedule
