Needs and Challenges for Big Data in Radiation Oncology.

Big Data is at the forefront of interest in radiation oncology, and several initiatives seek to understand what we can learn from it and how we can use it. Underlying these efforts are several needs and challenges specific to the problem of analyzing large samples of clinical data. There are technical challenges in data completeness, data integrity, and the technical systems able to collect and aggregate it, as well as cultural challenges around structured medical record management. Further complications are encountered in the legal and ethical challenges that must be respected to insure patient privacy. These challenges are discussed in the context of a learning health system in radiation oncology.
