Data collection for cancer patients
is recognized as an important task in the USA, where the National Program of
Cancer Registries (NPCR) administered by the Centers for Disease Control and
Prevention collects data on the occurrence, type, extent, and location of the cancer, and the type of initial treatment. The International Consortium for
Health Outcomes Measurements (ICHOM) aims at providing a global resource of
in-use outcome measures and risk adjustment factors by medical condition and
creating a global standard for measuring results.
These initiatives will enable
public health professionals to understand and address the cancer burden more
effectively. We have recently proposed to use the pre-treatment, planning, and
treatment outcomes data for cancer patients undergoing radiation therapy to
provide guidelines for optimal choice of both radiation modality and planning
for new patients. It is important to determine the most influential patient
features (or their combinations) that has the strongest correlation with the
outcomes. We propose an Overlap Volume Histogram as a valuable representation
of size and shape for tumor and organs at risk important for planning.
