Finding patients with pheochromocytoma - a rare but deadly hormone disease

What is it about?

Pheochromocytoma is a rare hormone disease, which is relatively easy to treat but notoriously difficult for doctors to diagnose. It can be fatal unless found and operated. We identified 588 patients diagnosed with pheochromocytoma from 1977 to 2016 in Denmark using public health registries and algorithms.

Why is it important?

We have found the -as of yet- largest group of pheochromocytoma patients ever identified in a population. This unique patient group can facilitate future research projects, hopefully improving our understanding and enabling faster diagnosis of this rare but dangerous disease

Identifying patients and writing this article was an immensely time-consuming and challenging first research project for me. The article mainly describes a scientific methods and is in itself not particularly interesting for doctors or pheochromocytoma patients. However, I hope that follow-up projects will lead to improvements in the management of pheochromocytoma to benefit both patients and doctors. I also hope, that the methods described can inspire researchers from other fields to use health registries for research into rare diseases.
