CS Extension--Lung: Can extension be coded to 10 (Tumor confined to one lung) when either an autopsy or a CT scan describes the tumor as a mass of a specified size located in one lobe of the lung without any description of extension and no available TNM provided? See Discussion.
Example 1: Lung primary within the right lower lobe described clinically as greater than 3 cm on scan but was found to be 3 cm at autopsy.
Example 2: CT scan February shows 2 cm mass in RUL.
In both cases, the only tumor description was the size of tumor without any information regarding extension.
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.
Yes, assign code 10 [Tumor confined to one lung] for a mass in one lobe when none of the descriptions in codes 11 to 80 are documented.
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.
CS Lymph Nodes--Colon: What criteria is used to distinguish between code 30 [Regional lymph nodes, NOS] and 80 [Lymph nodes, NOS] when positive lymph nodes are removed during a colon resection but the lymph node location is not stated? See Discussion.
Example 1: Descending colon excision: Metastatic adenocarcinoma in 8 of 9 lymph nodes.
Example 2: Hepatic flexure and en bloc resection of liver. Adenocarcinoma in 3 of 10 lymph nodes.
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.
Code positive nodes included with the resected specimen as regional lymph nodes, NOS when the location is not stated. See number 3.e under the general instructions for coding CS lymph nodes.
Based only on the information provided, code CS lymph nodes 30 [Regional lymph nodes, NOS] for both examples.
Diagnostic Confirmation: How is this field coded for a case with a cytology that is suspicious for ductal carcinoma and the clinical diagnosis is carcinoma? See Discussion.
SINQ 20031152 states that histology for this type of case is to be coded per the clinical diagnosis of "carcinoma." Does it follow then that Diagnostic Confirmation is to be coded 8 (clinical diagnosis only)? Would we code Diagnostic Confirmation differently if the clinician stated that the diagnosis of malignancy was confirmed by the suspicious cytology?
Code diagnostic confirmation as 8 [clincial diagnosis] when there is a suspicious cytology and a physician's clinical diagnosis. Do not accession cases with only suspicious cytology.
Code diagnostic confirmation as 8 when the clinician's diagnosis of malignancy is confirmed by the suspicious cytology. It is still a clinical diagnosis made by the physician using the information available for the case.
Diagnostic Confirmation--Leukemia: How is this field coded when the clinician confirms that the diagnosis of CML is based on a combination of the clinical picture and positive cytogenetic studies?
Assign code 1 [Positive histology]. For leukemia only, assign code 1 for positive hematologic findings including peripheral blood smears, CBCs and WBCs.
Cytogenetics studies would have been done on blood. Therefore, histology provided diagnostic confirmation as it would with smear, bone marrow, or other special study of blood cells.
Reportability--Melanoma: Is the final diagnosis for an excisional skin biopsy of "compound nevus with severe cytoarchitectural atypia and regression" reportable if a re-excision may be clinically indicated because there is an "overlap of morphology between malignant melanoma and nevi with severe atypia, and there's evidence of regression"?
Compound nevus with severe atypia is not reportable unless also stated to be malignant melanoma or melanoma in situ.
Neoadjuvant Treatment/Date Therapy Initiated--Breast: If Tamoxifen has been used since 2000 for the treatment of hyperplasia, should it be coded as neoadjuvant treatment for a 2004 diagnosis of breast cancer?
Do not code tamoxifen given for hyperplasia as treatment for breast cancer. In this case, tamoxifen started four years before the breast cancer diagnosis -- not treatment for breast cancer.
Date of Diagnosis/Ambiguous Terminology--Lung: Would the date of a PET scan that states there is a mass in the lung which is "in the range of malignancy " be coded as the date of diagnosis or would the date of a subsequent bronchoscopy with biopsy be used for diagnosis date because it confirms a malignancy?
The date of diagnosis in this case is the date of the bronchoscopy with biopsy.
"In the range of malignancy" is not one of the ambiguous terms that are reportable. Please see the list of reportable ambiguous terms on page 3 of the 2004 SEER manual. Do not accession cases based on ambiguous terms not found on the reportable list.
CS Extension--Pancreas, Head: When a tumor is described as having "vascular encasement of the celiac artery", is extension coded to 68 [tumor is inseparable from the celiac axis]?
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.
Code vascular encasement of the celiac artery to CS extension code 68 [tumor is inseparable from the celiac axis].
This celiac axis is a small (1cm) area of branching arteries. The celiac artery branches into hepatic, gastric, and splenic at the axis. Dissecting tumor out from around the celiac axis is very tricky and usually encasement by tumor is a sign of inoperability.
