Cancer stage
historically has been collected using three different
staging systems having three different purposes, data sets and rules.
The American Joint Committee on Cancer (AJCC), in collaboration with North
American standards setters, has developed a unified data set that will
combine and standardize the information needed to assign
stage in the AJCC (TNM), SEER (EOD) and Summary Stage (SS) 1977 and 2000
systems and to derive the T, N, M, stage group, Extent of Disease (EOD),
and SS applicable to each cancer site. Collaborative Stage (CS)
allows combined pathological and clinical “mixed” or “best” stage
to be captured. Additional data elements have been incorporated
into the CS data set to support and enhance the description
of the cancer stage.
Collaborative Stage provides the advantages of a unified data collection system designed to provide a common goal, to meet all the needs of the three staging systems, TNM, EOD, SS. It also provides a comprehensive system to improve data quality by standardizing rules for timing, clinical and pathologic assessments, and compatibility of descriptions across all of these systems for all cancer sites.
The Commission on Cancer (CoC) approvals program will require that the registrar record the T, N, M and stage groups as the physician has documented them in the medical record. This will enable comparison of CS and physician's stage and allow the CoC to assess the need for physician education in staging.
