## Abstract

Project Summary:
Title: Synthesizing Image-derived Heterogeneity with Genomic Measurements for Assessing Disease
Aggressiveness in Lower Grade Gliomas
WHO Grade II low grade gliomas (LGGs) are a type of brain tumor with an average incidence of 1/100,000
person-years within the population. Approximately 4000 people are diagnosed with this disease each year. It
has been observed that even after the first line of therapy (surgery, chemo-radiation), this disease inevitably
recurs. Further, it eventually transforms to a higher grade (WHO Grade III/IV) over time, a process referred to as
malignant transformation (MT). Even though MT is almost inevitable, the time-to-MT can be quite variable. In
aggressive cases, the LGG can undergo MT quite early in disease course, while in other (less aggressive) cases,
the duration to MT is much longer. This variability in time-to-MT can spell very disparate prognoses for the
patient. Such uncertainty in the disease evolution of LGGs also creates significant challenges for treatment man-
agement. Apart from creating uncertainty for the oncologist as how to appropriately manage the disease, this
also creates an anxiety-ridden scenario for the patients and their caregivers who try to understand their individual
condition. A rational strategy to understand and characterize the aggressiveness of LGGs can provide valuable
insight into the appropriate approach of treatment and surveillance for these patients.
In this proposal, we will address three specific aims that build a comprehensive, integrative statistical model,
which incorporates novel, complex imaging predictors, in addition to standard clinical and genomic characteris-
tics, for informing time-to-malignant transformation of LGGs. This tool can provide an assessment of anticipated
disease course that will help the patient and physician make suitable treatment decisions as well as to design
appropriate monitoring methods to track the progression and status of the tumor. Such a tool can also help
ameliorate some of the uncertainty and anxiety for the patients and their caregivers who will be better equipped
to understand their individual disease, in addition to enabling a more effective collaboration between patient and
physician to determine the most appropriate treatment approach. In particular, we will develop novel tumor het-
erogeneity objects, which efficiently capture inter- and intra-tumor variation in morphology and intensity-distribu-
tion characteristics. These objects are functional in nature and lie on nonlinear spaces. This introduces a signif-
icant challenge in statistical analysis such as defining association measures between the tumor heterogeneity
objects and genomic covariates, or incorporating these objects as predictors in an integrative statistical model.
To address these goals, we will use data on WHO Grade II LGG patients treated at the University of Texas MD
Anderson Cancer Center to identify imaging, genomic and clinical characteristics o...
