Question 20000265
Inquiry Details
References:
#1: SEER EOD-88, 3rd Ed, 7
#2: SINQ. 20031012
Question:
EOD-Extension: General instructions, page 7, note 3 states: " Extent of disease information obtained after treatment with neoadjuvant chemotherapy, hormone or immunotherapy has begun may be included." Because the SEER manual does not mention radiation treatment, can we use information from a lobectomy to code EOD if a patient has neoadjuvant radiation therapy?
Discussion:
Answer:
Radiation therapy was inadvertently omitted from the list. Please see SINQ 20031012 answer as to when the surgical information can be used to stage the case.
