**Note 3:** If a nodal station is in the area being imaged, biopsied, or in the surgical field and there is no mention of involvement, then assume that specific nodal station is negative.
**Note 4:** Code 9 is used when there is no relevant nodal information from diagnostic work up, biopsy or surgical resection documented.
**Note 5:** The assessment method is recorded in Lymph Nodes Distant Assessment Method [NAACCR Data Item # 3874].
