Quality Audit for ER, PR, HER2
▪ Rationale for selection of ER, PR, HER2
▪ No known problems (proactive) ▪ Important indicators for breast cancer ▪ Treatment decisions
▪ Prognostic value
▪ Used in staging in 2018
!3
Methods
!4
Methods
▪ Conducted literature review ▪ Established benchmarks/expected values
▪ Captured historical information on variables ▪ Collected and analyzed data in SEER*Stat ▪ Counts, rates; trends by year, by registry
▪ Compared data in SEER*DMS ▪ Consolidated value/Abstract value
▪ HER2 value/interpretation
!5
Results
▪ Expected values based on literature review ▪ ER positive: 70% ▪ PR positive: 70%
▪ HER2 positive: 15-20%
▪ Factors affecting expected values: Age, Race
!6
Results
ER/PR: Timeline of data collection changes
1: ER collected as Tumor Marker 1, PR as Tumor Marker 2 (EOD) until 2004
2: ER collected as SSF1, PR as SSF2 in CSv1 in 2004 3: Coding notes added in 2007 4: SSF1 and SSF2 with CSv2; add’l notes added in 2010, 2012

Results
HER2: Timeline of data collection changes
▪ Introduced with CSv2 in 2010, in SSFs 8-16 ▪ SSF9 + SSF11 + SSF13 + SSF14 = SSF15
▪ SSF15 (HER2: Summary Result of Testing) was not required; derived based on an existing algorithm if not coded
▪ Derived HER2 Recode (2010+)
▪ Updated notes: CSv0204 (2012), CSv0205 (2014)

Comparison of SSF8 IHC Lab Values and SSF9 IHC Interpretation used in HER2 Analysis for Breast Cancer
!25
HER2: SSF15 Summary Result of Testing
▪ SSF9 used in deriving HER2 Summary ▪ Complicated algorithms/rules exist for HER2 ▪ CS v2, SSF15, Note 3: If the results of one test are
available, and it is known that a second test is performed but the results are not available, use code 997 ▪ Algorithm for Derived HER2 Summary, Rule 1:
If FCO_comb=negative, then derived HER2=negative (regardless of what IHC test results indicate)
!26
Summary/Conclusions
▪ No major inconsistencies or problems identified with ER, PR, HER2; minor variance with unknowns ▪Missing/unknown data has improved ▪ Increasing trend in percent ER positive ▪ Benchmarks: identification necessary in the process ▪ Considerations for database modifications: e.g., add data
entry warnings, re-evaluate algorithms; SSDIs; training
