20110071 | Primary site: How is this field coded for an adenocarcinoma arising in a chronic perianal fistula without extension to the anal canal, but stated to arise in "ectopic rectal tissue"? See Discussion. | The patient underwent a resection of a perineal mass. Per review of slides it was stated to be "primary mucinous adenocarcinoma arising in a chronic perianal fistula." The adenocarcinoma was invasive into the dermal connective tissue and skeletal muscle, but there was no extension into the anal canal. The discharge diagnosis from the reporting facility called this adenocarcinoma of "ectopic rectal tissue in perianal area."
Should the primary site be coded to skin based on the dermal involvement and lack of anal or rectal involvement? Or, should the primary site be coded to rectum based on the physician's assessment that this adenocarcinoma arose in ectopic rectal tissue? |
For cases diagnosed 2007-2014: Code the Primary Site field to C210 [Anus, NOS]. This is an unusual and rare presentation. According to our expert pathologist, "There is no ideal site code [for] this case. I would code to C210. In this location it can at least be located by anyone who wants to get a look at such lesions. Because of the unusual location of this tumor, I would like to be able to code it to perineum, but it will be totally lost in those site codes as they represent extensive areas beyond perianal (skin of trunk, soft tissue of pelvis, and pelvis, respectively)... I would not code to rectum [because it would be] lost among too many primary rectal carcinomas." |

20110031 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned if patient initially diagnosed with granulocytic sarcoma on a vocal cord biopsy is subsequently diagnosed with acute myeloid leukemia more than 21 days later? See Discussion. | The patient has a history of refractory anemia with excess blasts diagnosed in 2008. A vocal cord biopsy performed on 6/2/2010 stated, "in view of a previous history of myelodysplastic syndrome this is indicative of transformation to acute leukemia" and consistent with granulocytic sarcoma. A bone marrow biopsy done on 7/19/2010 stated this was compatible with refractory anemia with excess blasts in transformation.
Granulocytic sarcoma is a solid manifestation of AML. When these diagnoses occur more than 21 days apart, are they separate primaries?
According to the WHO definition, this is acute myeloid leukemia complicating myelodysplasia. Which rule applies for this case? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case should be accessioned as two primaries. The first is refractory anemia with excess blasts in 2008, and the second is AML June 2, 2010.
As for the disease occurring in 2010, granulocytic sarcoma does not transform into AML. Per the Abstractor Notes section in the Heme DB under the term "granulocytic sarcoma," it indicates that "Myeloid sarcoma (also known as granulocytic sarcoma) may occur de novo; it may precede or coincide with AML, or represent an acute blastic transformation of myelodysplastic syndromes." This means that when granulocytic/myeloid sarcoma is seen with AML, it represents a solid manifestation of the systemically involved AML. In other words, it is all the same disease process (coded to AML) if it occurs simultaneously.
In this case, when the physician gave a provisional diagnosis of "transformation to acute leukemia" it indicated he saw the solid deposits of myeloid cells on the vocal cord. Per Rule M3, AML and myeloid (granulocytic) sarcoma appearing simultaneously are a single primary coded to AML. When the patient has AML, solid myeloid deposits (myeloid sarcoma) may appear. This is a manifestation of the AML rather than a new primary. Rule PH10 states to code the histology to AML.
Under the Transformation section in the Heme DB for refractory anemia with excess blasts (a chronic neoplasm), it indicates this disease process does transform to acute myeloid leukemia, NOS (an acute neoplasm). In this case, the chronic and acute disease processes were diagnosed at different times. Per Rule M10, abstract as multiple primaries when a neoplasm is originally diagnosed in a chronic (less aggressive) phase AND second diagnosis of a blast or acute phase more than 21 days after the chronic diagnosis.

20110008 | MP/H Rules/Histology--Vulva: How is histology coded for VIN III with focal invasion? See Discussion. | Per SINQ 20000442, the histology for CIN III with microinvasion is coded to 8077 [squamous intraepithelial neoplasia, grade III] per the matrix system rules, with a behavior code of /3 [malignant]. Coding the histology to 8077/3 per the matrix principle causes IF25_3 and MorphICDO3_P1 edits to fail. Flagging the first error resolves any reporting issue. How is the MorphICDO3_P1 edit resolved? | Assign 8076/3 [squamous cell carcinoma, microinvasive] for VIN III with focal invasion. This applies to all terminologies listed under 8077/2. The SINQ question from 2000 will be retired. | 2011 |

20110010 | Multiple primaries--Heme & Lymphoid Neoplasms: Is a recently diagnosed granulocytic sarcoma followed by a diagnosis of AML two primaries? See Discussion. |
6/10/10 Axillary lymph node biopsy was compatible with AML. The physician noted that the patient was diagnosed with granulocytic sarcoma [9930/3] in the axillary node. 6/15/10 Bone marrow biopsy compatible with AML FAB M1 [9873/3]. After induction, a second bone marrow biopsy on 6/30/10 shows persistent/refractory AML. The physician noted that the second biopsy is compatible with AML FAB M7 [9910/3]. Is the granulocytic sarcoma a chronic form of the disease? If so, do we have one primary diagnosed 6/10/10 with primary site coded to C42.1 and histology coded to 9873/3? Does the second biopsy on 6/30/10 represent the same primary even though the persistent disease is now FAB M7? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. Granulocytic sarcoma does not transform into AML. Per the Abstractor Notes section in the Heme DB under the term "granulocytic sarcoma," it indicates that "Myeloid sarcoma (also known as granulocytic sarcoma) may occur de novo; it may precede or coincide with AML, or represent an acute blastic transformation of myelodysplastic syndromes." This means that when granulocytic/myeloid sarcoma is seen with AML, it represents a solid manifestation of the systemically involved AML. In other words, it is all the same disease process (coded to AML) if it occurs simultaneously (i.e., at the same time or within 21 days of on another). Apply Rule M3 to this case which states to abstract a single primary when a sarcoma is diagnosed simultaneously or after a leukemia of the same lineage. Code the primary site to C421 [bone marrow] with histology coded to 9873/3 [acute myeloid leukemia, M1]. The FAB category is an older classification that is seldom used. Changes from FAB 1 to FAB 7 do not constitute a new primary. SEER*Educate provides training on how to use the Heme Manual and DB.

20110121 | MP/H Rules/Histology--Esophagus: Will the AJCC TNM 7 having separate stage groupings for squamous cell carcinoma and adenocarcinoma result in coding histology for a tumor of mixed squamous cell carcinoma and adenocarcinoma to squamous cell carcinoma because it has the poorer prognosis? See Discussion. | Per the CS Esophageal Schema, Note 4, there are now separate stage groupings for squamous cell carcinoma and adenocarcinoma. Should a tumor of mixed histopathologic type be classified as a squamous cell carcinoma?
|
Do NOT use the Collaborative Stage Manual to determine the histology code. For CS STAGING purposes only, coding should be based on the squamous cell carcinoma component of this tumor.
The Multiple Primary and Histology Coding Rules Manual is the correct source for coding histology. For cases diagnosed 2007 or later, the following steps are used to determine the histology code:
Open the Multiple Primary and Histology Coding Rules manual. For an esophagus primary, use the Other Sites Histo rules to determine the histology code because esophagus does not have site specific rules.
Start at Rule H8 because this is an invasive histology (assuming this is a single tumor). which states that one should code the appropriate combination/mixed code from Table 2 when there are multiple specific histologies.
Find Other Sites for Table 2 under the Terms & Definitions section of manual.
Locate the appropriate mixed code for squamous cell carcinoma and adenocarcinoma in column 1. Per column 3, the correct histology is adenosquamous carcinoma. Per column 4, the correct histology is 8560/3. |

20110019 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when bilateral testes are involved with lymphoma? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This is a single primary per Rule M2 which indicates to abstract a single primary when there is a single histology. Code the histology to 9590/3 [lymphoma] and the primary site to C629 [testes. Unless your software has edits that prevent coding laterality for lymphomas, code the laterality as bilateral. Up to half of extranodal lymphomas occur in multiple sites, particularly in paired sites.

20110129 | MP/H Rules/Histology--Lung: How many primaries are accessioned if a pathology report for a right upper lobectomy with a chest wall resection describes the disease as 1) two foci of poorly differentiated non-small cell carcinoma, 2) mixed adenocarcinoma and non-mucinous bronchioalveolar carcinoma, each present as a separate focus? See Discussion. |
This case was abstracted as two primaries, adenocarcinoma, acinar and papillary types [8255/3] and non-mucinous bronchioloalveolar carcinoma [8252/3] per Rules M5 and M10. If this is reported as only two primaries, what is the stage for each tumor? The non-small cell tumors were the most invasive, but they were not a separate primary per Rule M10. Final pathology diagnosis for a RUL lobectomy and chest wall resection: Carcinoma of the lung with the following features: 1. Non-small cell carcinoma, poorly differentiated (see comment). Two foci in same lobe: 10 cm and 3 cm (largest dimensions of each tumor). Invades pleura (PL3), main bronchus and chest wall invasion present. 2. Adenocarcinoma and bronchioloalveolar carcinoma (see comment). Histologic subtype: Acinar and papillary (adenocarcinoma); non-mucinous (BAC). Two foci in same lobe: up to 1.0 cm. Pleural invasion absent, chest wall invasion absent. 3. Metastatic carcinoma in 5/7 peribronchial LN's. Two histologically distinct neoplasms identified in the lobectomy/chest wall resection specimen: Poorly differentiated non-small cell carcinoma, present as two foci; and adenocarcinoma and non-mucinous bronchioloalveolar carcinoma, each present as a separate focus. |
SEER will answer the question about the number of primaries to accession. Submit questions about stage to the CoC CAnswer Forum. For cases diagnosed 2007 or later: Accession two primaries: a mixed adenocarcinoma, acinar and papillary types [8255/3] and a bronchioloalveolar carcinoma, non-mucinous [8252/3]. The steps used to arrive at this decision are: Determine the histology code for each tumor prior to applying the Multiple Primary Rules to determine the number of primaries to accession. There are two non-small cell carcinomas, NOS; the histology code for these two tumors will be 8046/3. There is a single adenocarcinoma with acinar and papillary subtypes tumor, the histology for this tumor will be 8255. There is a single bronchioloalveolar carcinoma, non-mucinous subtype tumor; the histology for this tumor will be 8252/3. Open the Multiple Primary and Histology Coding Rules manual. Choose one of the three formats (i.e., flowchart, matrix or text) under the Lung Multiple Primary rules to determine the number of primaries. Start at the MULTIPLE TUMORS module, Rule M3, because this patient has multiple tumors. The rules are intended to be reviewed in consecutive order within the module (from Rule M3 to Rule M12 in this case). Stop at the first rule that applies to the case you are processing. This patient's adenocarcinoma with acinar and papillary subtypes [8255/3] and non-mucinous bronchioloalveolar carcinoma [8252/3] are multiple primaries. Perform a second pass through the Multiple Primary rules to determine whether the two non-small cell carcinomas [8046/3] are multiple primaries or manifestations of the same primaries identified in Step 3. Start at Rule M3 again because this patient has multiple tumors. Again, these rules are intended to be reviewed in consecutive order within the module (from Rule M3 to Rule M12 in this case). Stop at the first rule that applies to the case you are processing. This patient's non-small cell carcinomas, NOS [8046/3] are a single primary when compared to the adenocarcinoma with acinar and papillary subtypes [8255/3] and non-mucinous bronchioloalveolar carcinoma [8252/3]. Both of these histologies are more specific types of non-small cell carcinoma per the Lung Histology Groups and Specific Types Chart (Chart 1). You can also apply Rule M10 for both non-small cell carcinoma, NOS [8046/3] compared to adenocarcinoma with acinar and papillary subtypes [8255/3] and non-small cell carcinoma, NOS [8046/3] compared to non-mucinous bronchioloalveolar carcinoma [8252/3]. |

20110144 | Reportability--Heme & Lymphoid Neoplasms: Is steroid resistant idiopathic thrombocytic purpura (ITP) the same as refractory thrombocytopenia [9992/3]? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Idiopathic thrombocytic purpura (ITP) is not a synonym for refractory thrombocytopenia (RT). ITP is not a reportable disease. See Appendix F.
Under the Alternate Names section in the Heme DB, the only synonym for refractory thrombocytopenia is "RT." ITP is not listed as a synonym for refractory thrombocytopenia.

20110094 | Surgery of Primary Site--Breast: Is a "nipple sparing mastectomy" coded to 30 [subcutaneous mastectomy] or 40 [total (simple) mastectomy] if the nipple/areolar complex was not removed but the pathology specimen indicates some breast skin was removed? See Discussion. |
In the past, the SEER Manual indicated that code 30 [subcutaneous mastectomies], which captured nipple-sparing mastectomies, would rarely be used because it was not typically performed as treatment for a malignancy. This note was removed from the 2010 SEER Manual, Appendix C. Code 30 which now states, "A subcutaneous mastectomy is the removal of breast tissue without the nipple and areolar complex or overlying skin." More "nipple-sparing mastectomies" are now being performed at certain facilities.
Should the Surgery of Primary Site field be coded to 30 when a nipple-sparing mastectomy with reconstruction is performed, even if there is skin removal? Or, does the skin removal indicate that this is not a subcutaneous mastectomy, and therefore code 43 [Total (simple) mastectomy with reconstruction, NOS] applies? |
Code Surgery of Primary Site to 30 [Subcutaneous mastectomy] for this case.
Assign code 30 when the nipple and areolar complex are NOT removed. Assign code 40 (or higher) when the nipple and areolar complex ARE removed. |
