The GDC released survival analysis and other enhancements in the Xanthopoulos release.
- The GDC transitioned to using lifelines an open-source Python library for survival analysis that provides tools for modeling time-to-event data, including Kaplan–Meier estimation, Cox proportional hazards regression, and other methods for analyzing censored observations
- Days-to-follow-up values for available data were added to survival analysis calculations.
Details on updates to survival analysis are available in the GDC Data Portal User's Guide.
This release honors the legacy of Basilis C. Xanthopoulos, continuing the GDC tradition of celebrating pioneering scientists.

DID YOU KNOW!...that the GDC has high coverage whole genome sequencing (WGS) data from The Cancer Genome Atlas (TCGA) program? See the FAQ on Finding High Coverage WGS Data for additional information.
Basilis C. Xanthopoulos (1951-1990) was a pioneering Greek theoretical physicist whose work in general relativity significantly advanced the understanding of gravitational-wave interactions and spacetime structure. He is best known for the Chandrasekhar–Xanthopoulos colliding plane wave model, which revealed deep connections between colliding gravitational waves and the geometry of rotating black holes described by the Kerr solution. His exact solutions to Einstein’s equations and influential studies of spacetime singularities, black holes, and gravitational waves remain important contributions to mathematical physics.
