EOD/Surgery of Primary Site--Melanoma: If a melanoma primary site is other than skin, vulva, penis, or scrotum should these fields be coded using melanoma schemes? See discussion.
Histology (Pre-2007): Do the terms "keratinizing" or "non-keratinizing" have to be present in the final diagnosis to use codes 8071 through 8073? See discussion.
Histology (Pre-2007)--Cervix: Is 8384/3 [adenocarcinoma, endocervical type] a specific histology type that must be stated or does it apply to any adenocarcinoma arising in the endocervical? Should the ICD-O-3 histology code of 8384/3 [Adenocarcinoma, endocervical type] be used for final diagnoses of "adenocarcinoma of the endocervix" or "adenocarcinoma of the cervix"?
EOD-Extension/EOD-Lymph Nodes--Cervix: How do you code these fields when the cancer extended to the pelvic wall and there are periaortic LN metastases?
Reportability/Behavior Code--Bone Marrow: Is T-cell large granular lymphocytic leukemia SEER reportable? Pages 102, 147, 156, 160-162 and 167 of the ICD-O-3 list it as 9831/1, but on page 17 this is listed as 9831/3.
Date of Diagnosis/Histology (Pre-2007)--Breast: When there is a delay between the clinical diagnosis of a malignancy and the surgical resection of the primary site, can the resection be used to code the date of diagnosis, extension, size of the primary tumor, and histology? See discussion.
EOD-Extension/EOD-Lymph Nodes--Rectosigmoid: How do you code these fields for a scan-based clinically staged T3 N1 rectosigmoid primary in a patient who received chemotherapy and radiation prior to a resection that demonstrated invasion only into the muscularis and no positive lymph nodes?
Reason for No Cancer-Directed Surgery: Could you explain why this field would be coded to 1 [Cancer-directed surgery was not recommended] or 2 [Contraindicated due to other conditions] for a case that presents with distant metastasis at diagnosis?
