EOD-Lymph Nodes/EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined--Lung: How do you code these fields for clinically positive lymph nodes when the result of neoadjuvant treatment is that the lymph nodes are pathologically negative? See discussion.
Multiple Primaries (Pre-2007)--Skin: If a patient presents with two separate lesions on the left cheek (i.e., left lateral cheek and left upper cheek) that both are histologically confirmed to be superficial spreading melanoma on the same day, is this coded as one or two primaries?
Reason no treatment/Surgery of Primary Site: Does the "Reason for No Cancer-Directed Therapy" field only relate to the "Surgery of Primary Site" field? If so, for what diagnosis years is that effective? Have SEER's coding guidelines changed over time? See discussion.
Histology--CLL/SLL: If a tissue diagnosis of "small lymphocytic lymphoma" is made six months after an initial blood diagnosis of "chronic lymphocytic leukemia" should the histology be updated from 9823/3 to 9670/3?
Diagnostic Confirmation--Testis: How do you code this field when a testicular mass is confirmed to be cancer on physical exam and testicular antigen, but the orchiectomy specimen was negative and yet the final signout diagnosis on the medical record was "testicular cancer"?
Histology (Pre-2007)--Kidney: What code is used to represent the histology "renal cell carcinoma with granular cell morphology"? Kidney primary with diagnosis of renal cell CA with granular cell morphology. Do we code as granular cell carcinoma? Is the term "morphology" synonymous with "type"? See discussion.
Histology (Pre-2007): Can adenocarcinoma in either a villous or tubulovillous polyp or adenoma be coded as histology for sites other than colon or rectum? See discussion.
Multiple Primaries (Pre-2007)--Bladder/Prostatic Urethra: When invasive TCC of the bladder and TCC in-situ of the prostatic urethra are diagnosed at the same time, are they reportable as two primaries? See discussion.
First Course Treatment: What code is used to represent each treatment modality field when there is no indication that a particular modality of treatment was recommended or started?
