Question:
EOD/Summary Stage--Eye: How is stage coded for a patient with extranodal non-Hodgkin lymphoma involving bilateral choroids (single focus, both sites) and no lymph node involvement? Since the eyes are a paired site, is this two separate extranodal sites? If so, there are no Summary Stage or EOD tumor codes that best fit this scenario.
Discussion:
Answer:
Assign as Stage IV as recommended by our expert hematological oncologist. This is a rare occurrence and this type of presentation does not fit the definition of intraocular extension. Stage IV is probably the best stage for this type of presentation, since there are two extranodal organs involved, even though they involve a bilateral site.
EOD Primary Tumor: 700
SS: 7 (Distant)
