abstract = {Standard of care treatment options at glioblastoma relapse
are still not well defined. Few studies indicate that the
combination of trofosfamide plus etoposide may be feasible
in pediatric glioblastoma patients. In this retrospective
analysis, we determined tolerability and feasibility of
combined trofosfamide plus etoposide treatment at disease
recurrence of adult glioblastoma patients.We collected
clinicopathological data from adult progressive glioblastoma
patients treated with the combination of trofosfamide and
etoposide for more than four weeks (one course). A cohort of
patients receiving empiric treatment at the investigators'
discretion balanced for tumor entity and canonical
prognostic factors served as control.A total of n = 22
progressive glioblastoma patients were eligible for this
analysis. Median progression-free survival (3.1 vs 2.3
months, HR: 1.961, $95\%$ CI: 0.9724-3.9560, P = .0274) and
median overall survival (9.0 vs 5.7 months, HR: 4.687,
$95\%$ CI: 2.034-10.800, P = .0003) were significantly
prolonged compared to the control cohort (n = 17). In a
multivariable Cox regression analysis, treatment with
trofosfamide plus etoposide emerged as a significant
prognostic marker regarding progression-free and overall
survival. We observed high-grade adverse events in n = 16/22
$(73\%)$ patients with hematotoxicity comprising the
majority of adverse events (n = 15/16, $94\%).$ Lymphopenia
was by far the most commonly observed hematotoxic adverse
event (n = 11/15, $73\%).This$ study provides first
indication that the combination of trofosfamide plus
etoposide is safe in adult glioblastoma patients. The
observed survival outcomes might suggest potential
beneficial effects. Our data provide a reasonable rationale
for follow-up of a larger cohort in a prospective trial.},
