c. her2 in breast cancer from any tissue site specimen
Conclusion to this good discussion is that there exists a need to develop a mechanism to note an observation made that is a proxy statement - specifically, an observation about a primary neoplasm location made on a metastatic specimen.
What are we measuring when assessing "treatment effect"?
Is this a histologic change? Viability of tumor cells?
Primary site
Lymph node
Briefly discussed, but general comments confer that this is a histologic feature property of measure. Will address and confirm at next work group meeting
