20081138 | MP/H Rules/Histology--Lung: What is the correct histology code for a neuroendocrine neoplasm described as a carcinoid and also referred to as oncocytic? See Discussion. | Left mainstem bronchus mass excised: metaplastic endobronchial mucosa with submucosa containing an infiltrating poorly diff malignant tumor. Origin of tumor is not identified in overlying mucosa. IHC stains will be performed. Addendum #1. IHC stains show well diff neuroendocrine neoplasm, favor carcinoid. Recommend sending this to expert in lung neoplastic pathologist. Addendum #2. (lung path specialist) oncocytic neuroendocrine neoplasm. Is this 8246 or 8290 or something else? |
For cases diagnosed 2007 or later, code as 8246 [Neuroendocrine carcinoma, NOS]. According to our pathologist consultant, the neuroendocrine description is more specific than the oncocytic description in this case. | 2008 |

20081134 | MP/H Rules--Breast: For tubulolobular carcinoma, do we use 8522? See Discussion. |
Path comment: This mixed variant of ductal and lobular carcinoma has been called in the past tubulolobular carcinoma, however, more recently is a mixed pattern of ductal and lobular carcinoma and not a variant of lobular carcinoma. |
For cases diagnosed 2007 or later, use rule H18 and assign code 8524 [lobular mixed with other types of carcinoma]. According to the MP/H rules, tubular is not a specific type of duct or lobular. This is based on the latest WHO classification of breast tumors. The combination histology of tubular and lobular will be reviewed during the upcoming revision of the MP/H rules. |

20081062 | MP/H Rules/Date of Diagnosis/Behavior--Brain and CNS: How many primaries would be reported when a December 2004 MRI shows a pineal region mass with the major differential consideration being pineocytoma; a November 2007 MRI that shows the mass has almost tripled in size; and the December 2007 resection final diagnosis is consistent with pineoblastoma? How would diagnosis date[s] and behavior code[s] be coded? See Discussion. | Dec. 2004 MRI of brain: Pineal region mass. The major differential consideration given patient's gender, age group, and imaging characteristics is pineocytoma. The differential includes pineoblastoma or germ cell line tumor. These are felt less likely. Nov. 2005 MRI brain: stable exam since last MRI. No change in size. Nov. 2007 MRI studies: pineal mass has almost tripled in size. Dec. 2007 Surgical resection of pineal tumor: High grade (WHO Grade IV) pineal parenchymal neoplasm consistent with pineoblastoma. |
For cases diagnosed 2007 or later: Abstract as separate primaries:
Complete two abstracts when a previously diagnosed non-malignant tumor transforms or progresses to a malignancy. Refer to the CDC/NPCR guidelines for Data Collection of Primary Central Nervous System Tumors, 2004. Malignant transformation is discussed on page 50. |

20081019 | Multiple Primaries--Lymphoma: How many primaries are abstracted for a patient with a 1995 periaortic lymph node biopsy showing lymphocytic lymphoma, diffuse small cleaved probable intermediate grade B cell positive, followed by stomach biopsies on 6/18/05 showing diffuse large B cell lymphoma and on 6/24/05 showing malignant lymphoma, tumor cells positive for [CD20] B cell respectively? | For cases diagnosed prior to 1/1/2010:There are two primaries:
According to the Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table, 9673 [Malignant lymphoma, lymphocytic, diffuse, intermediate] and 9680 [Malignant lymphoma, large B-Cell, diffuse] are separate primaries. Again, according to the table, 9680 [Malignant lymphoma, large B-Cell, diffuse] and 9591 [Malignant lymphoma, non-Hodgkin, NOS] are the same primary. 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. |

20081025 | MP/H Rules/Histology--Anus: What is the correct histology code and MP/H histology rule to use for AIN-3 arising in a polyp? See Discussion. | Patient has colonoscopy with excision of small 5mm polyp in rectum (no mention of anus or anal canal); path reads out: AIN-3 (anal intraepithelial neoplasm grade 3).
In coding the histology using the "Other Sites" rules, H2 would be the first rule that applies for this case. However, we lose the fact that the AIN-3 arose in a polyp (H3). Is this how SEER wants these cases coded? |
For cases diagnosed 2007 or later, apply rule H2 and assign histology code 8077/2 (squamous intraepithelial neoplasia, grade III). Apply the rules in order, H2 precedes H3. | 2008 |
|
20081061 | Histology--Breast: What is the histology code for a 2007 diagnosis of basal-type breast carcinoma? | Code basal-type breast carcinoma to 8500/3 [Infiltrating duct carcinoma, NOS]. Basal-type breast carcinoma is a subtype of infiltrating duct carcinoma thought to have a poorer prognosis. There is no specific ICD-O-3 code for basal-type breast carcinoma. |

20081075 | 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. |
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.

20081051 | MP/H Rules/Histology--Prostate: Path said adenocarcinoma of the prostate with an endometroid adenocarcinoma component. What histology code is used? | For cases diagnosed 2007 or later: Assign code 8500 [duct carcinoma]. According to The World Health Organization (WHO), the term endometrioid carcinoma of the prostate is now called Prostate Duct Carcinoma. Using Rule H11 (one type), code 8500 (duct carcinoma) for this rare type of tumor. Do not stop at Rule H10 because this is not acinar. |

20081063 | MP/H Rules--Breast: How many primaries should be abstracted when a patient has a mass at 6:00 that showed poorly differentiated ductal carcinoma and a hypoechoic nodule at 9:00 that was excised with no real tumor present there though path showed angiolymphatic invasion by carcinoma throughout the entire specimen? See Discussion. | Palpable mass in right breast at 6:00. Path stated 'poorly differentiated ductal carcinoma with extensive necrosis and extensive angiolymphatic invasion. Focal high grade comedocarcinoma (1%)'. Another hypoechoic nodule was seen at the 9:00 position. This mass was excised from surrounding tissue. This mass was more like an inflammatory mass; there was no real tumor present there. Path report stated "Breast mass 9:00 excisional biopsy - angiolymphatic invasion by mammary carcinoma throughout the entire specimen." Is this two primaries because of the two different histology codes: 8500 and 8010? |
For cases diagnosed 2007 or later, abstract as a single primary using rule M3 (a single tumor is always a single primary). There was one tumor present according to the information provided. The second specimen was not a separate tumor ("There was no real tumor present there"). | 2008 |
|
20081011 | Surgery of Primary Site/CS Reg LN Exam/Scope Regional LN Surgery--Rectum: How are these fields coded when a patient develops a non-tumor related complication that requires an additional sigmoid resection that removes 2 additional lymph nodes one week following a low anterior resection that removed 4 lymph nodes? See Discussion. | Patient had a low-lying rectal cancer that was biopsied and then treated with radiation and chemo followed by a low anterior resection. Four nodes were removed. There was no residual tumor. The patient returned one week later due to a rectal bleed, thought to be an abscess. During surgical exploration it was found that the anastomosis had broken down and it was decided to do a sigmoid colectomy. Residual disease was not suspected. Two additional nodes were removed. | Surgery of primary site: Assign code 30 [low anterior resection]. Code the most extensive surgery (i.e. the highest surgery code) applicable.
CS Reg LN Exam: Code 04 [four nodes removed].
Scope of regional lymph node surgery: Code 5 [4 or more regional lymph nodes removed].
The sigmoid colectomy was performed for a surgical complication, thus it was not cancer-directed therapy. The regional lymph nodes removed during that procedure were not removed to diagnose cancer or stage the disease, and they were not removed during the initial treatment. Please see SEER manual for instructions for coding Regional Lymph Node Surgery. |
