Surveillance Epidemiology and End Results (SEER)

At a talk I attended today, this resource of patient cancer diagnoses  
was mentioned as an example of publicly available clinical data. A  
quick look over the documentation suggests it might be an interesting  
project to produce an RDF version of the data set.

The SEER limited-use data* include SEER incidence and population data  
associated by age, sex, race, year of diagnosis, and geographic areas  
(including SEER registry and county)
