Question:

Grade--Liver: How should grade be coded for a liver lesion treated with radio frequency ablation (RFA) followed by a transplant showing moderately differentiated hepatocellular carcinoma? See discussion.

Discussion:

The SEER Manual emphasizes the importance of coding grade only prior to neoadjuvant treatment as systemic treatment and radiation can alter a tumor's grade. This patient did not have neoadjuvant chemotherapy or radiation, but did undergo a prior surgical procedure (RFA) in an attempt to destroy tumor tissue. The subsequent transplant showed residual moderately differentiated HCC.

Answer:

For this case, record the grade specified even though it is after RFA. RFA is not systemic or radiation treatment and should not alter the grade.
