Tumor Tip of the Week – When ER/PR Intensity Score Given as a Range

Match the Scenario with the correct Answer

Answer: ER Allred Score: X9 Not documented in medical record/ER (Estrogen Receptor) Total Allred Score not assessed, or unknown if assessed

1. ER Positive 85% Intensity Score 3
2. ER Positive 85% Intensity Score 2/3
3. ER Positive 85% Intensity Score 2-3

Scenario C matches the Answer ER Allred Score X9, see discussion below:

SSDI manual contains instructions to calculate Allred Score

• Proportion + Intensity=Allred [See table below.]

Scenario A: ER Positive 85% Intensity 3+

• Proportion Score of 85% Equates to a 5
• Intensity Score =3
• Allred Score= 8 [Proportion Score of 5 + Intensity Score of 3]

Scenario B: ER Positive 85% Intensity 2/3

• Proportion Score of 85% Equates to a 5
• Intensity Score = 2 out of 3, so a 2
• Allred Score= 7 [Proportion Score of 5 + Intensity Score of 2]

 Scenario C: ER Positive 85% Intensity 2-3

• Proportion Score of 85% Equates to a 5
• Intensity Score listed as a range 2-3, thus you cannot use this to assign a Score
• Allred Score= X9 [Allred score cannot be assigned because Intensity Score is unknown]

CAnswer Forum Post If the intensity score is documented as 2-3, or 1-2, you cannot use this to assign the Allred Score. Your Allred Score would be unknown (code 9).  https://cancerbulletin.facs.org/forums/forum/site-specific-data-items-grade-2018/124736-intensity-score-given-as-a-range
