Reportability--Skin: Is a non-small cell carcinoma [8046/3] of the skin SEER reportable?
Non-genital skin primaries with a histology code equal to or less than 8110 are not reportable to SEER; therefore, the combination of C44_ and 8046/3 is not reportable.
EOD-Extension--Lung: For a left upper lobe lung tumor that extends across the fissure into the left lower lobe, should this field be coded to 10 [Tumor confined to one lung] or 77 [Separate tumor nodules in different lobe]?
For cases diagnosed 1998-2003: Assign EOD extension code 10 [Tumor confined to one lung]. EOD extension code 10 applies to a single tumor within one lung, even one that crosses over a fissure into another lobe. EOD extension code 10 is not correct if the tumor extends to the pleura, or if there is atelectasis, obstructive pneumonitis or malignant pleural effusion. Code 77 is incorrect because that is a separate tumor nodule in a different lobe.
EOD-Lymph Nodes/EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined--Cervix: What codes are used to represent these fields for a cervix primary when the only information on lymph nodes is a CT of the pelvis showing "pelvic adenopathy" (no surgery was done)?
Code the EOD-Lymph Nodes field to 9 [unknown]. Code the Pathologic Review of Number of Regional Lymph Nodes Positive field to 98 [No nodes examined] and the Lymph Nodes Examined to 00 [No nodes examined] because there was no resection of the primary organs. Adenopathy, NOS, per SEER guidelines, is not coded as lymph node involvement
Reportability--Breast: Is a final path diagnosis of "phyllodes tumor, borderline (malignant, low grade)" reportable if the comment states "Features favor the diagnosis of a borderline phyllodes tumor (or also called malignant phyllodes tumor of low grade)"?
No, borderline phyllodes tumors (PT) are not reportable. The ICD-O-3 code is 9020/1. According to the WHO Classification of Tumours of the Breast and Female Genital Organs, borderline PT's are also called low grade malignant PT's.
EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined/Surgical Procedure of Other Site--Kaposi Sarcoma: How do you code these fields for a groin mass excision containing 4 lymph nodes for a Kaposi sarcoma case that presented with multiple skin lesions?
Code the EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined fields to 99 99 for Kaposi cases that present systemically and for those that present in more than one site (which includes cases with more than one skin subsite involved at diagnosis). There are no "regional" lymph nodes for such cases. This represents a majority of currently diagnosed Kaposi cases. However, for localized Kaposi cases, you can count the number of regional lymph nodes positive and examined if the primary site selected has a regional lymph node chain(s) associated with it (e.g., soft palate, hard palate, or a skin subsite).
For cases diagnosed 1/1/2003 and after: Code the groin mass excision in the Surgical Procedure of Other Site field to 1 [Non-primary surgical procedure performed; Non-primary surgical resection to other site(s), unknown if whether the site(s) is regional or distant].
MP/H Rules/Histology--Thyroid: How many primaries are to be reported and what histology is to be coded for an anaplastic/undifferentiated thyroid carcinoma with sarcomatoid transformation likely arising in association with a papillary thyroid carcinoma? Thyroid contains one tumor: 12.5 cm in greatest dimension...almost completely replaces entire thryroid gland.
For cases diagnosed 2007 or later:
This is a single primary using rule M2; a single tumor is always a single primary.
The histology code for this case is 8260/3 [Papillary carcinoma of thyroid]. Begin with Histology Coding rule H8. Stop at rule H17 and code the histology with the numerically higher ICD-O-3 code.
Surgery of Primary Site--Ovary: What code is used to represent this field when a patient has a history of a previous organ removal and has additional surgery/organ removal for a present cancer (e.g., History of a 1984 hysterectomy and in 2003 has ovarian primary treated with BSO)?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 52 [Bilateral salpingo-oophorectomy WITH hysterectomy].
EOD-Extension--Thyroid: Is this field coded as involvement of the thyroid capsule if the thyroidectomy path specimen reveals papillary thyroid ca "tumor present within capsular blood vessels?"
For cases diagnosed 1998-2003: Tumor present within the blood vessels of the thyroid capsule is localized (extension code 30). The tumor has not penetrated the capsule itself if it is contained within the blood vessels.
Keep in mind that tumor size determines the extent of disease for thyroid extension codes 10, 20, 30 and 40.
