Starting with cancer cases diagnosed in 2010, CSv2 is the required staging schema for cancer reporting. There were significant and numerous changes from Version 1 to Version 2 on cancer cases. All cancer reporters working in American College of Surgeons (ACoS) facilities (or in non-ACoS facilities that follow ACoS guidelines) need to view this training webcast (or have attended an on-site presentation) to successfully complete the Collaborative Staging for these cases.
The CSv2 101 webcast available from this page explains some of the basics of this staging system.
Two Web-based trainings on state reporting requirements are also available.
Note: Only a general explanation of CSv2 is given. Collaborative Stage is being phased out and will no longer be used starting with cancer cases diagnosed in 2016.
