Do you consider a solitary IHC+ sentinel inguinal node lymph node to have the same implication for treatment as a single positive node or multiple positive nodes?
Pt with 1.3 cm Merkel cell (buttock) excised with negative margins. Two sentinel inguinal nodes sampled and one is IHC+.
Answer from: Radiation Oncologist at Community Practice
Implication and outcome are different but what intervention is needed is uncertain. In view of Merkel cell histology, would favor adjuvant RT to primary and nodal region.
