Collaborative Staging Schema v02.05

The Collaborative Stage Data Collection System is a carefully selected, medically relevant set of data items that describe how far a cancer has spread at the time of diagnosis. Most of the data items have traditionally been collected by cancer registries, including tumor size, extension, lymph node status, and metastatic status.
