Temozolomide rechallenge in recurrent malignant glioma by using a continuous temozolomide schedule
admin Despite advances in first-line therapy, there are some accumulation on communication of glioblastoma multiforme (GBM) at recurrence. Temozolomide (TMZ) is substantially tolerated and haw hit state despite preceding TMZ danger if new pane schedules are used.The authors reviewed their undergo with a constant TMZ schedule (50 mg/m2 daily), presented at advancement after customary 5-day TMZ. Patients were reportable in 3 groups: 1) GBM after advancement on customary TMZ; 2) GBM at prototypal repetition after termination of accepted occurrence and adjuvant TMZ; and 3) patients with another anaplastic gliomas at ordinal recidivate on customary TMZ.In Group 1, 21 patients with a norm geezerhood of 54 eld (range, 33 years-68 years) conventional a norm of 3 cycles (range, 2-12 cycles) of constant TMZ at 50 mg/m2. Overall clinical goodness (complete response, coloured response, and steady disease) was 47%, with 6-month progression-free activity (PFS) of 17%. In Group 2, 14 patients with GBM, norm geezerhood 52 eld (range, 38 years-62 years) conventional constant TMZ at advancement after initial TMZ/radiotherapy (RT) and adjuvant TMZ. The norm quantity after adjuvant TMZ was 3 months (range, 2 months-10 months). A norm of 5 cycles of TMZ was given, and 6-month PFS was 57%.

Toxicities were temperate and substantially tolerated; lymphopenia was ordinary but no earnest expedient infections were identified.Although retrospective, our results shew that constant regular brass of TMZ is an astir program despite preceding TMZ therapy. The superior tolerability of this program haw earmark forthcoming compounding with another alkylating agents or with new therapies. person 2008. © 2008 dweller person Society. (Source: Cancer)
