Grade, Differentiation--Bladder: If the only indication of grade for a bladder primary is "grade 2, NOS," and we do not know the grading system being used by the pathologist, is the numeric grade 2 coded?
Primary site--Head & Neck: When there is invasive in one subsite and in situ in another, do you code the subsite with the invasive only? Would the correct site be C320, C328, or C329? See discussion.
Date of Diagnosis: When the clinical information on a scan indicates a history of cancer, how do you code the month and/or year of diagnosis given these terms: "early in year," "late in year," "2-3 months ago," "7 months ago," "new diagnosis." See Description.
Other Cancer-Directed Therapy--Hematopoietic, NOS: Is there a hierarchy for selecting which code to use when a patient receives more than one type of "other treatment"? See Description.
Reason for No Surgery of Primary Site: Does code 2 [Contraindicated due to other conditions; autopsy only case] or code 1 [ Cancer-directed surgery not recommended] have priority when coding this field for extensive tumors not surgically treated because of existing comorbidities? See discussion.
MP/H Rules/Histology--Lung: How many primaries are accessioned if a pathology report for a right upper lobectomy with a chest wall resection describes the disease as 1) two foci of poorly differentiated non-small cell carcinoma, 2) mixed adenocarcinoma and non-mucinous bronchioalveolar carcinoma, each present as a separate focus? See Discussion.
EOD-Clinical Extension--Liver: How do the segments of the liver described by AJCC Manual correspond to the lobes of the liver described by the SEER EOD Manual? See Description.
