ObjectivesObjectives
• Understand why collaborative staging was created
• Learn the concepts of collaborative staging for breast cases
![Page 3: Putting the Puzzle Together: Breast Collaborative Staging](https://reader035.fdocuments.in/reader035/viewer/2022062422/56813ff0550346895dab0354/html5/thumbnails/3.jpg)
Collaborative StagingCollaborative Staging• 5yr group effort among all standard setters in
North America
• Designed by and for cancer registrars to code the facts about a cancer case
• General rules apply to all sites/histologies unless superseded by site-specific rule
![Page 4: Putting the Puzzle Together: Breast Collaborative Staging](https://reader035.fdocuments.in/reader035/viewer/2022062422/56813ff0550346895dab0354/html5/thumbnails/4.jpg)
Collaborative StagingCollaborative Staging
• Used for cases diagnosed 1/1/2004 and forward– CSv2 for cases diagnosed 1/1/2010 and forward
• Derives:– AJCC TNM– SEER Summary
• Understand SEER Summary and TNM is necessary in order to analyze cases

Collaborative StagingCollaborative Staging
• Allows both clinical and pathologic information to be used to determine stage– Pathologic information takes precedence
![Page 6: Putting the Puzzle Together: Breast Collaborative Staging](https://reader035.fdocuments.in/reader035/viewer/2022062422/56813ff0550346895dab0354/html5/thumbnails/6.jpg)
Collaborative StagingCollaborative Staging• CS Solution: Mixed or “Best Staged”
– Result: more relevant to actual practice– Fewer unstageable cases
