2022 SEER Manual
First Course Treatment/Neoadjuvant Therapy--Melanoma: How are the three Neoadjuvant Therapy data items (Neoadjuvant Therapy, Neoadjuvant Therapy--Clinical Response, Neoadjuvant Therapy--Treatment Effect) coded when a patient is diagnosed with melanoma in the lymph nodes with no primary skin site identified? The physician gives immunotherapy as neoadjuvant therapy with planned and carried out surgical resection of involved lymph nodes following completion of immunotherapy. There is no "planned definitive surgical resection of the primary site" as no primary site was found,
Assign code 0 to each of the three Neoadjuvant Therapy data items in this situation.
We will add an example to the coding instructions for these data items in the next release of the manual.
