Very low mutation burden is a feature of inflamed recurrent glioblastomas responsive to cancer immunotherapy.
Abstract
Several immunotherapy clinical trials in recurrent glioblastoma have reported long-term
survival benefits in 10-20% of patients. Here we perform genomic analysis of tumor
tissue from recurrent WHO grade IV glioblastoma patients acquired prior to immunotherapy
intervention. We report that very low tumor mutation burden is associated with longer
survival after recombinant polio virotherapy or after immune checkpoint blockade in
recurrent glioblastoma patients. A relationship between tumor mutation burden and
survival is not observed in cohorts of immunotherapy naïve newly diagnosed or recurrent
glioblastoma patients. Transcriptomic analyses reveal an inverse relationship between
tumor mutation burden and enrichment of inflammatory gene signatures in cohorts of
recurrent, but not newly diagnosed glioblastoma tumors, implying that a relationship
between tumor mutation burden and tumor-intrinsic inflammation evolves upon recurrence.

Dr. Ashley's primary research focus is laboratory based, investigating the role of
immunotherapy as a novel approach to the treatment of tumors of the central nervous
system (CNS). Since beginning his appointment at the faculty level at Duke in August
of 1995 his activities have centered on two main areas of investigation. The first
involves both in vivo and in vitro studies of the use of molecular therapeutics to
target a CNS tumor associated antigen. The second area of interest comprises a det

Current research interests have application to the design and analysis of cancer clinical
trials. Specifically, interests include the use of time-dependent covariables within
survival models, the design of phase II cancer clinical trials which minimize some
of the logistical problems associated with their conduct, and the analysis of longitudinal
studies with informative censoring (in particular, quality of life studies of patients
with advanced cancer).

Brain tumors are diagnosed in more than 20,000 Americans annually. The most malignant
neoplasm, glioblastoma, is also the most common. Similarly, brain tumors constitute
the most common solid neoplasm in children and include astrocytomas of the cerebellum,
brain stem and cerebrum as well as medulloblastomas of the cerebellum. My colleagues
and I have endeavored to translate the bench discoveries of genetic mutations and
aberrant protein expressions found in brain tumors to better understan

mutations in IDH1 and IDH2 in 70% of progressive malignant gliomas. These are somatic
