Report Question ID Question
20021139 Date of Diagnosis/EOD-Extension--Placenta: How do you code these fields for a patient who presents with a vaginal metastatic lesion for a placenta primary? Should EOD-Extension be coded to 60 [Other genital structures NOS: vagina, ovary, broad ligament, fallopian tube] or 85 [metastasis other than lung]? See discussion.
20021140 EOD-Extension--Head & Neck: How do you code extension for a supraglottic larynx primary with "pre-epigolottic space" invasion?
20021141 EOD-Extension--Lung: When only minimal information is available, such as scans and needle biopsies, should EOD extension be coded to localized or unknown? See discussion.
20021142 Date of Diagnosis: If an originally diagnosed "benign" tumor is later discovered to have "metastasized", should the date of diagnosis be back-dated to the date the original tumor was discovered or to the date the metastatic disease was identified?
20021143 Multiple Primaries (Pre-2007)--Breast: Should just one primary be reported when only ductal carcinoma in situ is diagnosed initially but the mastectomy performed as part of the first course of cancer-directed therapy, but more than 2 months after diagnosis, contains a diagnosis of invasive ductal carcinoma? See discussion.
20021144 EOD-Extension--Colon: What code is used to represent this field for a mid-ascending colon primary that invades through muscularis propria and into subserosal fibroadipose tissue that also presents with a "separate serosal nodule" of carcinoma within cecum that is consistent with a tumor implant (cT3, N0, M1)?
20021146 Primary Site--Lymphoma: Is the primary site likely to be extranodal for a lymphoma that presents in an extranodal site and lymph nodes which are regional for that site? Is the primary site also likely to be extranodal if an extranodal site and lymph nodes are excised? See discussion.
20021147

Other Cancer Directed Therapy--Hematopoietic, NOS: Is "aspirin" treatment for primary polycythemia? See discussion.
20021149 EOD-Extension--Head & Neck: In the absence of a clear surgical or pathologic description of how the salivary gland involvement relates to the head and neck primary, do we code the involvement as direct extension, further extension or metastasis? See discussion.
