What was measured

Global Health Status is calculated from two questions on the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire \[EORTC QLQ\]-C30. The question responses range from 1 "very poor" to 7 "excellent" such that a higher response indicates better quality of life (QOL). The mean of these responses is linearly transformed to a range of 0 (worst) to 100 (best). Change is calculated as time point - baseline such that a positive change value indicates worse symptoms compared to baseline.

Analysis population: Questionnaires were not completed by all QOL population participants. Therefore, only 30/96 on the conventional arm and 23/95 on the dose-dense arm have both baseline and mid-cycle 4 data.

Groups in this outcome

Conventional Adjuvant TMZ

Concurrent radiation therapy with concurrent temozolomide (75 mg/m2) up to 49 doses. Starting four weeks after completion of RT, 100mg/m2 adjuvant temozolomide days 1 to 5 of 28 day cycle for 6 cycles, up to 12 cycles.

Dose-dense Adjuvant TMZ

Concurrent radiation therapy (RT) with concurrent temozolomide (75 mg/m2) up to 49 doses. Starting four weeks after completion of RT, 75mg/m2 adjuvant temozolomide days 1-21 of 28 day cycle for 6 cycles, up to 12 cycles.
