Online Help

Registry Plus Online Help (RPOH) is no longer maintained by CDC. The last publicly available complete version was released in 2015. Because it no longer reflects current cancer registry standards, we have withdrawn it from the website.

When RPOH was first released, paper coding manuals were still the norm. At that time RPOH replaced many pounds of paper needed to abstract and code cancer cases. Now most cancer registry standard setters publish their manuals electronically as downloadable PDFs or via a web service.
