CS Extension--Retinoblastoma: When the degree of extension differs between the retinas, how is extension coded for simultaneous bilateral retinoblastoma?
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 the CS extension code that corresponds to the greatest level of extension seen in either eye, excluding information from enucleation.
Record extension based on enucleation in Site Specific Factor 1.
Record bilateral disease under laterality. For retinoblastomas, bilaterality is not a component or consideration for staging.
Primary Site/CS Extension/CS Lymph Nodes--Lung: How are these fields coded for untreated lung primaries when only limited information is available from scans, bronchoscopies and biopsies? See Discussion.
3/13/04 CT scan Chest: extensive mediastinal, subcarinal, rt hilar lymphadenopathy; separate tumor mass in medial rt lung
3/16/04 Bronchoscopy: RLL/RML completely obstructed with extrinsic compression. Impression: CA of lung with hilar adenopathy.
Bronchial wash: PD non small cell CA
Bx RLL: up to 0.2 cm PD Adenocarcinoma c/w primary lung CA.
Treatment not recommended.
Expired 5/03/04.
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.
The primary is in the right lung according to the available information.
Assign CS extension code 10 [Tumor confined to one lung]. The only information on extension is that there is a tumor in one lung.
Assign CS Lymph Nodes code 20 [Mediastinal and subcarinal lymph node involvement]. The CT scan confirms mediastinal and subcarinal lymphadenopathy.
Code tumor Size as 999 [Unknown]. "Completely obstructed" is not a size. Do not code the size of the biopsy specimen.
CS Reg LN Pos/Exam--Colon: For a patient with both a prostate and colon primary, if the pathology report indicates that 2 of the 3 regional lymph nodes to the colon are positive for a prostate malignancy, how should these fields be coded for the colon primary?
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.For the colon primary, code Reg LN Pos 00 [all nodes negative]. Code Reg LN Exam 03 [three nodes examined].
Three lymph nodes were examined and found to be negative for metastatic colon cancer.
Grade, Differentiation/Priorities: Which has priority, the differentiation or the nuclear grade for a liver biopsy histology described as "well differentiated hepatocellular carcinoma, nuclear grade 3/4"?
For most sites, differentiation has priority over the nuclear grade when both are specified (excluding breast and kidney). Assign grade code 1 [well differentiated] to the example above.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Thyroid: How is histology coded for the tumor(s) that exist when the thyroidectomy addendum diagnosis is "Morphologic and IHC evaluations reveal two tumors: papillary thyroid carcinoma and squamous cell carcinoma." See Discussion.
The original final diagnosis after a thyroidectomy is "papillary carcinoma of the thyroid with an adjacent invasive squamous cell carcinoma, moderately differentiated." Per the additional addendum comment: "The findings can be interpreted in one of 2 different ways. Either there is a collision tumor of papillary thyroid and squamous cell carcinoma (with the squamous cell ca originating at a site other than the thyroid gland.) Or, less likely, there is a malignant squamous differentiation in the papillary thyroid carcinoma." A university hospital consultation report states the diagnosis as: "Spindle cell squamous cell carcinoma arising in association and from papillary carcinoma, predominantly tall cell variant..." Is this 2 thyroid primaries: 8344/3 [papillary carcinoma, tall cell] and 8074/3 [squamous cell carcinoma, spindle cell]?
For tumors diagnosed prior to 2007:
Our pathologist consultant agrees with the consultant's diagnosis. Therefore, abstract this as one primary of the thyroid. Code the histology as 8344 [Papillary tall cell]. This is the most appropriate histology code available for this complex case.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
CS Tumor Size--Bladder: Is tumor size coded to 080 when the bladder mass is described as "greater than 8 cm in diameter"?
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.Based on the information provided above, code CS tumor size 080 [8 cm]. Code the information that is avaliable. Since size of tumor is not used to stage bladder cancer, an approximation is adequate.
CS Site Specific Factor/Terminology--Breast: Does the term "focal areas" of in situ carcinoma qualify as "minimal" in situ component when coding SSF6 field (assessment of the invasive and in situ components present) in the CS breast scheme?
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, the term "focal areas" of in situ carcinoma describes a minimal in situ component.
Reportability/Primary Site--Head & Neck: If a wedge resection/shield resection is performed on the lower lip for SCCA and the path report refers to "lip, NOS" with no mention of vermilion border, is this case reportable?
Review the operative and pathology reports, and the physical exam for mention of "mucosal surface" (reportable) or "skin" (not reportable). If neither are mentioned, lip, NOS is reportable per the ICD-O-3 code of C009.
Histology (Pre-2007): What is the difference between code 8244/3 composite carcinoid (combined carcinoid and adenocarcinoma) and 8245/3 adenocarcinoid tumor?
For tumors diagnosed prior to 2007:
Assign code 8244/3 [composite carcinoid] when there is a combination of adenocarcinoma and carcinoid tumor.
Assign code 8245/3 [adenocarcinoid] when the diagnosis is exactly "adenocarcinoid."
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
