Grade/Cell indicator--Lymphoma: How is Grade/Cell indicator coded for anaplastic large cell lymphoma? See Discussion.
The SPCM states cell indicator codes take precedence over grade/differentiation codes for lymphoma and leukemia cases.
For cases diagnosed prior to 1/1/2010:Because there is no cell indicator information, code 9 [cell type not determined] in the grade/cell indicator field. Do not code grade for lymphoma. For lymphoma and leukemia this field is the cell indicator.
For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Behavior--Breast: How is this field coded for a case in which the final diagnosis reports DCIS, but the CAP protocol or microscopic findings show microinvasion? See Discussion.
1. Path report for breast cancer has final diagnosis as 'DCIS' but the CAP protocol in the body of the report says 'microinvasion seen, T1mic.'
2. Path report says 'DCIS' in the final diagnosis and microinvasion is identified in the microscopic portion of the report, but it is not in CAP protocol format and not stated in the final diagnosis.
Code both scenarios /3 [malignant (invasive)]. Information regarding behavior is not limited to the final diagnosis or the CAP protocol. See page 84 in the 2007 SEER manual:
Code the behavior as malignant /3 if any portion of the primary tumor is invasive no matter how limited; i.e. microinvasion.
Reportability/Histology--Brain and CNS: Is an "inflammatory myofibroblastic tumor" reportable for Brain and CNS sites? See Discussion.
Histology code 8825/1 (Inflammatory Myofibroblastic Tumor) is not listed in the ICD-0-3 Primary Brain and CNS Site/Histology listing for reportable Brain/CNS tumors.
If the inflammatory myofibroblastic tumor is primary in one of the sites specified below and diagnosed 1/1/2004 or later, it is reportable.
Reportable brain and CNS tumors are any benign and borderline primary intracranial and CNS tumors with a behavior code of /0 or /1 in ICD-O-3 diagnosed 1/1/2004 and later, of the following sites:
Cerebral meninges C700
Spinal meninges C701
Meninges, NOS C709
Cerebrum C710
Frontal lobe C711
Temporal lobe C712
Parietal lobe C713
Occipital lobe C714
Ventricle, NOS C715
Cerebellum, NOS C716
Brain stem C717
Overlapping lesion of brain C718
Brain, NOS C719
Spinal cord C720
Cauda equine C721
Olfactory nerve C722
Optic nerve C723
Acoustic nerve C724
Cranial nerve, NOS C725
Overlapping lesion of brain and central nervous system C728
Primary site--Bladder: What is the correct subsite for "interureteric ridge"? See Discussion.
Description: 4 mm nodule at base of bladder near interureteric ridge.
For this case, assign code C670 [Trigone of bladder]. The description for this case states that the tumor location is the base of the bladder. Base is a synonym for trigone.
The interureteric ridge (or interureteric crest, or interureteric fold) is a fold of mucous membrane extending accross the bladder between the two ureteric orifices. The trigone is located below the interureteric ridge.
MP/H Rules/Multiple Primaries--Head & Neck: How many primaries should be reported when an invasive squamous cell carcinoma of the right mandibular body (C06.9) was diagnosed in 2004 (treated with surgery and radical neck dissection), and an invasive squamous cell carcinoma of the left buccal mucosa (C06.0) was diagnosed in 2007? See Discussion.
According to the MP/H Rules, it appears Rule M12 would apply since none of the others fit and these would be a single primary.
For cases diagnosed 2007-2014:
Based on the information provided, the primary site code for the 2004 primary should be C031 [mandibular gingiva, lower alveolar mucosa, etc.].
The 2007 diagnosis would be a separate primary according to rule M7 because the patient was disease free following treatment for the 2004 diagnosis. C031 and C060 are different at the third character.
CS Site Specific Factor--Head & Neck: Can SSF 1-6 be coded using clinical information only, or does the source of information for lymph nodes need to be pathological?
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.CS Site Specific Factors 1 through 6 for head and neck sites may be coded using either clinical or pathologic information.
Surgery of Primary Site/Scope Regional LN Surgery--Breast: How should these fields be coded when a sentinel lymph node dissection removes one-to-three axillary lymph nodes and a total/simple mastectomy is done?
Assign code 41 [Total (simple) mastectomy, NOS WITHOUT removal of uninvolved contralateral breast] for Surgery of Primary Site. Assign code 2 [Sentinel lymph node biopsy] for Scope of Regional Lymph Node surgery. Code 41 applies to a total/simple mastectomy with any number of sentinel lymph nodes removed -- as long as all of the nodes removed are designated as sentinel nodes.
Grade: Can FIGO grade be used to code Grade/Differentiation? See Discussion.
SINQ 20020059 says not to use FIGO grade to code differentiation. It also says SEER is evaluating whether the ICD-O-3 sixth digit differentiation codes accurately represent the FIGO grade. For the time being, do not code FIGO grade. What is the result of the evaluation? Any new information regarding FIGO grade?
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.Do not code FIGO grade in the grade field. The conversion from a three-grade system to a four-grade system does not work for FIGO grade three. Since FIGO G3 includes both Poorly differentiated and undifferentiated, it cannot be converted.
FIGO grade may be captured in a CS site specific factor in the future.
Rosette-forming glioneuronal tumor of the 4th ventricle is a new WHO entity. There is no current ICD-O-3 code for this. The best code available at this time is 9505/1.
CS Extension--Bladder: How should this field be coded for a high grade urothelial carcinoma with "focal micropapillary features and invasion of lamina propria, with a note stating there is invasive carcinoma focally involving thin muscle bundles...difficult to distinguish whether muscularis propria or muscularis mucosae"?
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 CS Extension code 15 [Invasive tumor confined to subepithelial connective tissue (tunica propria, lamina propria, submucosa, stroma)]. The information provided confirms invasion of the lamina propria (code 15) but is not definitive enough to assign a code higher than 15.
