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.
Multiple Primaries (Pre-2007)/Recurrence--Breast: Has SEER established a priority of medical opinions to determine the number of primaries or a time parameter establishing recurrence? When a pathologist and a physician refer to the subsequent reappearence in the same breast as both "recurrence" and "new primary"? See Description.
Histology (Pre-2007)--Breast: When the histology from a lumpectomy differs from that of a core needle biopsy, should the lumpectomy histology be coded? See Discussion.
Histology (Pre-2007)/Grading--Head & Neck: Can terms that commonly modify histologic types or grades be used if they are only expressed in the microscopic portion of the pathology report? See Description.
Histology (Pre-2007)--Kidney: Is 8316/3 [Cyst associated renal cell carcinoma] the appropriate code for 1) Cystic renal cell carcinoma, 2) Renal cell carcinoma mass with cystic areas and 3) Cystic renal cell carcinoma, clear cell type?
Multiple Primaries (Pre-2007)--Thyroid: Would a papillary carcinoma of the right lobe of the thyroid diagnosed approximately 2 1/2 years after a papillary carcinoma of the left lobe be coded as a second primary? See Description.
Multiple Primaries (Pre-2007): Whenever two hollow organs are diagnosed simultaneously with the same histology, one being invasive and the other in situ, can one assume that mucosal spread has occurred and that this situation represents one primary? In the absence of a physician statement, how do you determine mucosal spread from one organ to another?
Histology (Pre-2007)/Grade, Differentiation--All Sites: When the original pathology reports diagnosis indicates a grade and the review of slides (ROS) pathology report does not give a grade, can you code the histologic type from the ROS and the grade from the original pathology report? See discussion.
Multiple Primaries (Pre-2007)--Bladder: Is a 1998 transitional cell carcinoma of the bladder, followed by a 2001 squamous cell carcinoma of the bladder reportable as a second primary?
Multiple Primaries (Pre-2007)--Soft Tissue: Does SEER agree that one primary of the soft tissues of pelvis [C49.5] should be reported when a pathologic diagnosis for bilateral herniorrhaphies is "right and left inguinal hernias with low grade spindle cell sarcoma"?
