Timed Temozolomide Treatment in Glioblastoma Patients: A Retrospective Study

AI simplified

Abstract

Patients taking morning temozolomide experienced a longer median overall survival of 1.43 years compared to 1.13 years for those taking it in the evening.

  • Morning administration of temozolomide is associated with improved overall survival in glioblastoma patients.
  • The difference in median overall survival suggests a potential benefit of timing in treatment delivery.
  • Among patients with MGMT-methylated tumors, morning treatment resulted in a median overall survival increase of 6 months.
  • Significant survival differences favoring morning administration were observed at years 1, 2, and 5.
  • Preliminary findings indicate that chronotherapy may enhance treatment outcomes for glioblastoma patients, particularly those with specific genetic markers.
