Question:

CS Site Specific Factor 6--Breast: Should we assume that the invasive portion of the tumor is being referred to when a pathologist provides only a single tumor size but includes both invasive and in situ descriptors when discussing the size of that tumor? See Discussion.

Discussion:

There seems to be subtle variations in wording and punctuation in these cases. Would these three examples be coded the same way?

Examples:

"invasive ductal carcinoma 2.0 cm, DCIS present"

"2 cm invasive ductal carcinoma with DCIS present"

"invasive ductal carcinoma 2.0 cm. DCIS present"

Answer:

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Code SSF6 050 [invasive and insitu components present, entire size coded in CS TS, size of invasive not stated, proportion invasive and insitu not known] when the size of the invasive portion is not provided and clarification is not available.

If possible, obtain clarification from the pathologist for phrases like these and document in a text field. For example, a pathologist may confirm that when he/she states "invasive ductal carcinoma 2.0 cm, DCIS present" the size of the invasive portion is 2 cm. If so, code CS tumor size 020 and SSF6 020 and explain in a text field.
