Is there any activity looking specifically at the use of Open Source software in the management of disease related data in Oncology patients?

I am a radiation oncologist interested in pursuing some Open Source development in the area of managing data associated with the management of cancer patients, specifically with a view to permitting QA of practice and acquisition of data that can be aggregated and compared.

I feel alone in this desire and would like to find some colleagues in the Oncology realm or some IT-savvy dudes who re prepared to work with a doctor to achieve something useful.
