Reportability: Is a case reportable if a benign diagnosis is obtained on a resection that follows a positive needle aspiration? See Discussion.
Fine needle aspiration of the thyroid diagnosis was "positive for malignant cells, favor medullary carcinoma." Subsequent thyroidectomy was reported as benign.
This case is reportable. The cytology is positive. Report as medulary carcinoma of the thyroid.
Race, ethnicity/Spanish surname or origin: If birthplace is Brazil or Portugal, patient's last name is on the Spanish Surname list, and there is no text to further clarify ethnicity, what is the correct Spanish Ethnicity code: 0 or 7? See Discussion.
See also SINQ 20081075.
Assign code 7 [Spanish surname only] when the last name is on the Spanish Surname list. This includes cases for which the birthplace is Brazil, Portugal or the Philippines and there is no text to further clarify ethnicity.
The instruction to use code 0 [Non-Spanish/Non-Hispanic] in the SEER manual on page 51 (#2) applies when the only information available is the birthplace or a statement of "Portuguese," "Brazilian" or "Filipino."
MP/H Rules--Breast: What is the histology code for a breast tumor that is ductal ca with focal squamous differentiation? See Discussion.
SINQ 20021062 states for cases Dx'd prior to 2007, use 8570. Is 8570 also used when the squamous differentiation is focal?
For cases diagnosed 2007 or later, use rule H14 and code the histology 8500 [duct carcinoma]. Ignore histologies described as "focal," "focus," or "foci." This instruction will be added to the histology rules in the upcoming revision of the MP/H manual.
CS Extension--Brain and CNS: How is this field coded for a malignant tumor presenting as a confluent lesion over right parietal, posterior frontal and thalamic regions?
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 40 [Tumor crosses the midline; Tumor involves contralateral hemisphere; Tumor involves corpus callosum (including splenium)]
The thalamus is located between the corpus callosum and the cerebellum and brain stem. A supratentorial tumor extending to the thalamus involves the corpus callosum (extension code 40) but has not yet reached the cerebellum or brain stem. Code 40 applies, but code 50 or any higher code is not applicable in this case.
Race, ethnicity/Spanish surname or origin: SEER Program Manual instructions state, "Portugese, Brazilians and Filipinos are not Spanish; Code non-Spanish (code 0)." How is that determined? Is that based SOLELY on birthplace? See Discussion.
The following are scenarios for which we would like clarification on how to code Spanish Ethnicity.
Birthplace Portugal; text states Spanish, south American or European Spanish
Birthplace Brazil, last name is on Spanish surname list; pt is married female. Text states "Hispanic female, NOS"
Birthplace Brazil or Portugal, text states patient is "Mexican", last name is on Spanish surname list
Information about Spanish origin is available for both of these cases; code the race as Hispanic. Use the SEER manual instruction when the only information available is that the patient was born in Portugal, Brazil or the Philippines. In the absence of additional information, do not assume Hispanic. However, if additional information is available stating that the patient is Hispanic, code as Hispanic.
Histology--Head & Neck: How do you code histology for a myofibroblastic sarcoma of the soft tissue of the head and neck?
Assign code 8825/3 [Myofibroblastoma, malignant]. According to the WHO Classification of Soft Tissue Tumors, "Low grade myofibroblastic sarcoma represents a distinct atypical myofibroblastic tumor often with fibromatosis-like features and predilection for the head and neck." Also called myofibrosarcoma.
CS Extension--Lung: Chest CT shows segmental atelectasis (CS EXT code 40), but patient had Left Lower Lobe lobectomy/Lymph Node dissection with no involvment outside the lobe (pleura and all margins neg). Do we still code the atelectasis (CS Ext 40) over confined to lung (CS EXT code 10)?
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 40 [Atelectasis/obstructive pneumonitis that extends to the hilar region but does not involve the entire lung (or atelectasis/obstructive pneumonitis, NOS)].
CS extension code 10 does not apply when any condition described in codes 20-80 exists.
CS Extension--Brain and CNS: How is this field coded for a malignant brain tumor that presents as a lesion with significant pressure on the left frontal ventricle and dilation of the right ventricles? See Discussion.
CS Extension code 30 includes tumor that invades or encroaches upon the ventricular system. Does significant pressure mean the same thing as encroach?
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 assign extension code 30 in this case unless there is evidence elsewhere of ventricular system involvement.
"Significant pressure" is not synonymous with encroachment or involvement. See the list of ambiguous terms for CS staging on page 121 of the 2007 SEER manual.
Reportability--Brain: Is angiocentric glioma, WHO grade 1 of the right frontal lobe reportable? If so, how is histology to be coded?
Angiocentric glioma is reportable. The best histology code currently available is 9380/1 [glioma, NOS; uncertain behavior].
According to the WHO Classification of Central Nervous System Tumours, Angiocentric glioma has a behavior of /1. WHO defines it as an epilepsy-associated stable or slowly growing cerebral tumour primarily affecting children and young adults; histopathologicaly characterized by an angiocentric pattern of growth, monomorphous bipolar cells and features of ependymal differentiation.
Surgery of Primary Site--Melanoma: Which surgery codes should be used for cases that have a 1 cm margin? See Discussion.
For a melanoma case the surgery codes in the 30's are to be used when margins are stated to be less than 1 cm. The codes in the 40's are to be used for cases where the margins are greater than 1 cm.
If the margin is exactly 1 cm, assign a surgery code from the 20-36 range. Use a code in the 40's only when the margin is greater than 1 cm.
