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 healthprofessionals 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 andshape for tumor and organs at risk important for planning.
