What was measured

The MDASI-BT is a 28-item patient-reported outcome measure assessing symptom severity and resulting interference with daily living in brain cancer patients. All items range from 0 (not present) to 10 (as bad as you can imagine). The symptom severity score is the average of the symptom severity items, given a specified minimum numbers were completed. A score worse than baseline by at least one is considered deterioration. 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 32/96 on the conventional arm and 24/95 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.
