Phase II Trial of Neo-adjuvant Temozolomide Prior to Combined Temozolomide and Concurrent Accelerated Hypofractionated External Beam Radiotherapy Followed by Adjuvant Temozolomide in Patients With Newly Diagnosed Glioblastoma Multiforme

Patients with GBM, who were deemed ineligible for any active protocols at our centre, received accelerated hypofractionation EBRT if 60Gy/20Fx using an IMRT technique with conventional dose of concomitant and adjuvant TMX as per the STUPP's TMZ schedule. Thirty five patients, 15 females and 20 males with a median age of 63 (range 31-78) were treated with a median KPS of 90 (range 50-100). Four patients had multicentric disease at presentation. Eight patients had biopsy only while the rest had a near total resection (n=14) and partial resection (n=13) with a median follow-up of 12.1 months, the median survival was 14.4 months.

Primary Outcome Measures:
  • Percent of patients completing the study treatment [ Time Frame: At one year ]
    To determine overall survival.

  • To assess toxicity of the regimen [ Time Frame: At one year ]
    Toxicity will be assessed and graded according to CTCAE-V3

Enrollment: 50
Study Start Date: December 2008
Study Completion Date: December 2014
Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Temozolomide, Accelerated Hypofractionated RT
Patient will receive two weeks of neo-adjuvant Temozolomide followed by Accelerated Hypofractionated RT for a total of 20 fractions for a total of 60Gy followed by Temozolomide for 12 cycles.
Radiation: IMRT Technique Radiation: IMRT and accelerated hypofractionation technique
Intervention is the technique and accelerated fractionation used to treat GBM
Radiation: neo-adjuvant TMZ followed by accelerated hypofractionated EBRT
Two weeks of neo-adjuvant TMZ followed by XRT+TMX followed by TMZ as adjuvant component
Drug: Temozolomide and Accelerated Hypofractionation RT

Detailed Description:
In this proposal, the total cumulative dose of TMZ is unchanged as compared to the doses used in the Stupp protocol. In this proposal, the dose of TMZ is the same, with the sole difference that TMZ will be given in a neo-adjuvant setting for two weeks and then continued at the same dose concurrently with the accelerated hypofractionated EBRT delivering 60Gy in 4 weeks. The adjuvant component of TMZ remains unchanged from current standard practice.
