Primary Site/EOD-Extension/EOD-Lymph Nodes--All Sites: What codes are used to represent these fields for an "extramedullary myeloid tumor (granulocytic sarcoma)" of the colon with positive or negative lymph nodes?
For cases diagnosed 1998-2003:
If only the extramedullary site is involved, such as colon, code the Primary Site field to the site of origin. Granulocytic or myeloid sarcoma is an exception to the rule that all leukemias should be coded to bone marrow as the primary site. Granulocytic sarcoma is a deposit of malignant myeloid cells in a site other than bone marrow (extramedullary). For EOD staging, granulocytic sarcoma [9930/3] is included in the Hematopoietic, Reticuloendothelial, Immunoproliferative and Myeloproliferative Neoplasms scheme and the Extension field is coded to 10 when the lymph nodes are negative, since it (like solitary plasmacytoma) is a localized deposit of tumor.
However, if the regional lymph nodes associated with the extramedullary primary site are involved, code the EOD-Extension field to 80 [Systemic disease] because the disease is no longer an isolated deposit of malignant granulocytes (in other words, it is not localized).
The EOD-Lymph Nodes field is coded to 9 regardless of whether or not the lymph nodes are involved because that is the only allowable code for that field.
EOD-Extension--Lung: If a CT scan indicates that a patient has evidence of "long-standing pneumonia," is that synonymous with "pneumonitis" for the purposes of coding extension for lung primaries?
No. These terms are not synonymous. For cases diagnosed 1998-2003, disregard the pneumonia and use the other available information to code extension.
Chemotherapy--Breast: In the absence of more specific information, is the insertion of a port-a-cath one month after mastectomy enough documentation to code chemotherapy to 88 [Recommended]?
Assign chemotherapy code 88 [Chemotherapy was recommended, but it is unknown if it was administered]. Be sure to confirm whether or not treatment was administered and update this code accordingly.
Primary Site--Breast: If a patient has multifocal tumors all in the upper outer quadrant of the breast, is the primary site coded to C-504 because all of the tumors are in UOQ or would the site be coded to C509 to reflect the fact that multiple tumors exist?
Code the primary site to C504 [Upper outer quadrant]. All disease is located in one quadrant, code that quadrant. When disease involves two or more quadrants and the point of origin cannot be determined, code C509 [Breast, NOS]. See 2004 SEER manual, page C-470 for instructions about invasive and in situ in different quadrants.
Reportability--Breast: Is a biopsy proven squamous cell carcinoma of the breast nipple reportable if a subsequent areolar resection shows foreign body granulomatous reaction to suture material and no evidence of residual malignancy in the nipple epidermis?
Yes, this case is reportable. The primary site is C500 [nipple]. There was a diagnosis of malignancy on 2/15/06: "Positive for malignancy." Even though no residual malignancy was found in the later specimen, that does not disprove the malignancy diagnosed on 2/15/06.
Reportability--Melanoma: Please explain how a CTR is to interpret the guideline in the MP/H rules (Cutaneous Melanoma): Evolving melanoma (borderline evolving melanoma): Evolving melanoma are tumors of uncertain biologic behavior. Histological changes of borderline evolving melanoma are too subtle for a definitive diagnosis of melanoma in situ. Is this to mean that evolving melanoma in situ is not reportable? Or should we follow the guidelines in SEER Question 20130022 that states the reportability terms for melanoma and melanoma in situ.
Follow the guidelines in SINQ 20130022 for now. When the MP/H rules are revised, new instructions will be implemented.
Surgery of Primary Site--Bladder: Should a TURB be coded to 27 [Excisional biopsy; SEER Note: Code TURB as 27] when there is obvious extravesicular extension demonstrated because the 2004 SEER Manual states "Do not code an excisional biopsy when there is macroscopic residual disease"?
Assign code 27 [excisional biopsy]. The site-specific instructions have priority over the general instructions. According to the instructions for coding surgery of the bladder, use code 27 for TURB.
CS Lymph Nodes--Colon: Are positive paracecal lymph nodes for cecal primaries coded to 10 [paracolic] or code 20 [cecal: anterior (prececal), posterior (retrocecal); NOS]?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Assign code 20 [Regional lymph node(s) for specific subsites]. Paracecal means near the cecum. Paracecal lymph nodes are regional nodes for the cecum and not for other colon subsites.
MP/H Rules/Multiple Primaries: When the pathology report from a FNA or other biopsy states an "in situ" carcinoma and the patient waits more than 60 days for a more definitive procedure which documents an "invasive" carcinoma, is this reported as two primaries?
For cases diagnosed 2007 or later:
No. When the invasive component is discovered as part of the work-up phase leading to treatment decisions, the case should not be abstracted as a multiple primary. In the rare instance when a patient has not been treated and is still having diagnostic work-up greater than 60 days after the malignancy is diagnosed, do not count the invasive diagnosis as a new primary.
