20021143 | Multiple Primaries (Pre-2007)--Breast: Should just one primary be reported when only ductal carcinoma in situ is diagnosed initially but the mastectomy performed as part of the first course of cancer-directed therapy, but more than 2 months after diagnosis, contains a diagnosis of invasive ductal carcinoma? See discussion. | How do we code this case in light of the EOD guideline that states we include all information collected within 4 months of diagnosis or through the completion of first surgery in the absence of disease progression when coding. | For tumors diagnosed 1998-2003:
Report this case as one invasive primary, unless stated to be two primaries by the clinician. This appears to be a single primary with different behaviors, rather than separate tumors.
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. |

20021087 | Multiple Primaries (Pre-2007)--Head & Neck: How many primaries are represented when a1998 invasive squamous cell carcinoma of the true vocal cord is followed by a 1999 diagnosis of in situ squamous cell carcinoma of the true vocal cord (called "recurrent" by the clinician), and in 2001 there is another invasive squamous cell carcinoma of the true vocal cord (no statement of recurrence)? Would your answer be any different if no statement of "recurrent" had been made in 1999? | For tumors diagnosed prior to 2007:
Code this case as two primaries, an invasive true vocal cord primary in 1998 and another invasive true vocal cord primary in 2001.
If there had been no statement of recurrence for the 1999 in situ diagnosis and the 1999 diagnosis was more than two months following the 1998 diagnosis, this case would be coded as three primaries.
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. |

20021063 | EOD-Pathologic Review of Number of Regional Lymph Nodes Examined: What code is used to represent this field when a path report from a lymph node biopsy or dissection describes lymph node "portions" or "fragments"? See discussion. | 1) Lymph nodes, right pelvic dissection: No evidence of malignancy in 4 portions of lymph node examined. (Should we code the number examined as 01, 04, or 97?) 2) Lymph nodes, left pelvic dissection: 5 fragments of lymph nodes show no evidence of malignancy. (Should we code the number examined as 05 or 97?) 3) Biopsy of right neck mass: Malignancy in fragments of lymph nodes. The following month, pt had a right modified lymph node dissection: 16/32 lymph nodes are positive for malignancy. (Should we code the number examined as 32, 33, 97, 98?) |
For cases diagnosed 1998-2003:
The total number of lymph nodes examined is recorded in EOD-Num of Reg LN Examined. If the number of actual lymph nodes represented by the "fragments" or "portions" cannot be determined, assign code 96, 97, or 98 as appropriate. 1) Based on the terminology "four portions of lymph node (singular)" code to 01 despite "dissection" terminology. 2) Code to 97 based on "fragments of lymph nodes (pleural)" terminology and procedure identified as dissection. 3) Code to 97 based on statement of "fragments of lymph nodes (pleural)" for biopsy plus dissection. |

20021099 | Reportability/Histology (Pre-2007)--Pancreas: Are the following pancreatic tumors with mention of "low grade malignant potential/borderline" reportable to SEER? If so, what histology and behavior codes should be used? See discussion. | 1. AFIP diagnosis: Pancreas, tail, resection: Mucinous cystadenocarcinoma (mucinous cystic neoplasm) of low grade malignant potential. Comment: There are no reliable histomorphologic features which can separate these neoplasms into benign and malignant tumors, and so we consider them all to be low grade malignant tumors.
2. Whipple resection: Intraductal papillary mucinous tumor of the pancreas with extensive low grade and multifocal high grade ductal dysplasia (so-called borderline tumor and carcinoma in-situ). |
For tumors diagnosed prior to 2007:
Both tumors are reportable to SEER.
1. Code the Histology and Behavior Code fields to 8470/3 [Mucinous cystadenocarcinoma, NOS].
2. Code the Histology and Behavior Code fields to 8453/2 [Intraductal papillary-mucinous carcinoma, non-invasive].
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. |

|
20021168 | Histology (Pre-2007)--Corpus Uteri: What code is used to represent the histology "endometrioid carcinoma with squamous differentiation" for an endometrium primary? | For cases diagnosed 2004-2006:
Endometrioid adenocarcinoma with squamous differentiation is coded 8570 [Adenocarcinoma with squamous metaplasia].
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. |

|
20021194 | Grade/Histology (Pre-2007)--All Sites: What code is used to represent these fields for the histology "High grade dysplasia (adenocarcinoma in situ)" or "AIN III/High grade AIN"? |
For tumors diagnosed prior to 2007: Code the Histology field for the first example to 8140/2 [Adenocarcinoma, NOS, in situ] and for the second example to 8077/2 [AIN, grade III]. For both of the cases code the Grade, Differentiation field to 9 [Cell type not determined not stated or not applicable]. The 6th digit (grade code) of ICD-O-3 describes how much or how little a malignant tumor resembles the normal tissue from which it arose. In contrast, "grade" is used in the examples above to describe the degree of dysplasia, from mild dysplasia (low grade) to severe dysplasia (high grade). Do not record the degree of dysplasia in the 6th digit grade field. For tumors diagnosed 2007 or later, refer to the MP/H rules for histology coding instructions. 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. |

20021206 | EOD-Extension--Breast: The SEER coding scheme classifies the in situ portion as less than 25% [code 14] or equal to or greater than 25% [code 15]. How do you code a pathologist's statement of "less than or equal to 25%"? See discussion. | "insitu ca constitutes less than or equal to 25% of the total mass." | For cases diagnosed 1998-2003:
Code the EOD-Extension field to 14 [invasive and in situ components present, size of entire tumor coded in Tumor Size AND in situ described as minimal (less than 25%)]. The pathologist did not use a code as defined by SEER. For cases described as "less than or equal to 25%", choose the lower of the two EOD code choices. |

20021173 | Histology (Pre-2007): What code is used to represent a review of slides histology of "in situ squamous cell carcinoma and multiple detached fragments of atypical papillary squamous epithelium; highly suspicious for invasive carcinoma"? See discussion. | The original pathologist indicated a final diagnosis of moderately differentiated squamous cell carcinoma. The slides were sent for review to another facility. The reviewing pathologist rendered the diagnosis stated in the question section. | For tumors diagnosed prior to 2007:
Code the Histology field to 8070 [squamous cell carcinoma].
The review diagnosis was also squamous cell carcinoma. The expression "atypical papillary squamous epithelium" does not modify the cancer histology.
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. |

20021070 | CS Extension/CS Lymph Nodes--Breast: How would you interpret the phrase "axillary lymph node tissue, not clearly a lymph node" or the phrase "satellite nodule of invasive tumor, left axillary lymph node or chest wall tissue"? See discussion. | A lumpectomy with axillary lymph node dissection and removal of nodule in anterior axillary line revealed negative lymph nodes. The nodule specimen was labeled "axillary lymph tissue, not clearly a lymph node". The microscopic description for that specimen stated "Fibroadipose tissue. A fragment of a lymph node is incidentally sampled in block 4 and it is free of tumor". The final path dx stated "Satellite nodule of invasive tumor, left axillary lymph node, or chest wall tissue. Comment: If the tissue is considered chest wall this would be a stage IIIB. If it is considered an intramammary satellite nodule, this is a stage I". The clinician repeated what the comment said, and added "If lymph node mets, this is a stage II." | Code the invasive tumor in the axillary area as a regional lymph node metastasis. According to the AJCC, cancerous nodules in the axillary fat adjacent to the breast, without histologic evidence of residual lymph node tissue, are classified as regional lymph node metastases. | 2002 |

20021092 | Histology/Primary Site--CLL/SLL: How should these fields be coded for a "chronic lymphocytic leukemia/small lymphocytic lymphoma" [CLL/SLL] diagnosed on a lymph node biopsy that is referred to by the clinician as CLL? See discussion. | Does the clinician's reference to this disease as CLL change the SEER rule to code to SLL if the disease arises in a lymph node or solid tissue? | For cases diagnosed prior to 1/1/2010:Code the Histology field to 9670/3 [Malignant lymphoma, small lymphocytic, NOS] and the Primary Site field to C77._ [lymph nodes] when CLL/SLL is diagnosed in lymph node or solid tissue, even if the clinician refers to CLL. When CLL/SLL is diagnosed in the blood, code as leukemia.
Refer to clarification #6 on the ICD-O-3 Errata and Clarifications. "...if disease is diagnosed only in the blood or bone marrow, code the primary site to C42.1, bone marrow and assign the leukemia morphology code. If the diagnosis is made on any other tissue (typically lymph nodes, lymphatic structures, breast, and stomach), code to the tissue involved and assign the lymphoma morphology. If the diagnosis is made on both blood or bone marrow and a tissue biopsy, code the tissue involved and assign the lymphoma morphology." For cases diagnosed 2010 forward, 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. |
