Reportability: Is penile intraepithelial neoplasia, differentiated type, reportable? See discussion.

Foreskin circumcision shows: Penile intraepithelial neoplasia, differentiated type (differentiated PeIN). If reportable, how would the histology and behavior be coded? Is this behavior /2?

For cases diagnosed 2018 and later

Differentiated penile intraepithelial neoplasia (differentiated PeIN), is reportable (8071/2).

Please note: Penile intraepithelial neoplasia, grade 3 (PeIN 3) is also reportable to SEER (C600-C609, 8077/2).

20031166 EOD-Regional Lymph Nodes--Breast: Are subpectoral nodes the same as interpectoral nodes and, therefore, regional for breast primaries? Subpectoral lymph nodes are regional nodes for breast primaries. Subpectoral is the term generally used to describe the placement of a prosthesis during reconstruction (under/behind the pectoralis major muscle). That is the same location for interpectoral, or Rotter's, nodes. Breast N/A 2003
20031082 EOD-Size of Primary Tumor: Pathologist states that the size of the tumor is difficult to measure but is greater than 3cm but less than 5cm. How would we code the tumor size?

For cases diagnosed 1998-2003:

Code the largest dimension mentioned, since that is the standard rule for coding tumor size. Keep in mind that tumor size is not used in analysis for certain sites such as stomach, colon & rectum, ovary, prostate, and urinary bladder. Tumor size is important for analysis for certain sites such as lung, bone, breast, and kidney.

20081017 Ambiguous terminology/Reportability--Leukemia: Is a 'suspicious peripheral blood smear' the same as a suspicious cytology? See Discussion. The final diagnosis on the path report for a peripheral blood smear is stated to be "suspicious for malignancy." The microscopic description states that the "lymphoid population raises the concern of chronic lymphocytic leukemia." Nothing further was done. Is this a reportable case? If so, should it be coded as a leukemia or a malignancy NOS?

For cases diagnosed prior to 1/1/2010:Do not accession a leukemia case based only on a "suspicious" peripheral blood smear. If a confirmed diagnosis, clinical confirmation or further information becomes available later, accession the case at that time.

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.

20081026 MP/H rules/Multiple primaries: Is a 2007 cytology diagnosis of adenocarcinoma in bile duct a new primary for a patient with a 2005 diagnosis of adenocarcinoma of gallbladder? See Discussion.

A case abstracted for an adenocarcinoma of gallbladder (C23.9) in 2005. In 2007, cytology diagnosis of adenocarcinoma in bile duct(C24.0). Oncologist calls this recurrence. There is no pathologist statement of recurrence.

Using Other Sites multiple primary rules, rule M10 indicates this is multiple primaries. Sequence 01 dx in 2005 and sequence 02 dx in 2007. Is this correct? There is no statement of a primary tumor; the MP/H rules talk in terms of mass, lesion, tumor in a primary site.

 For cases diagnosed 2007 or later, abstract the 2007 bile duct diagnosis as a new primary unless it is described as metastatic. N/A N/A 2008
20130077 Reportability--Heme & Lymphoid Neoplasm: What is the histology code if a myeloproliferative disorder is reportable should a physician suspect this diagnosis and treats the patient? See Discussion. Physician suspects patient has a myeloproliferative disorder and treats her with a phlebotomy and Hydrea. Patient receives Hydrea during an inpatient stay, but does not see the Heme/Onc again. The patient is subsequently only seen by a Palliative Medicine physician who also states she has an underlying myeloproliferative disorder. The patient died while an inpatient.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

This is a reportable diagnosis and should be accessioned with the histology coded to 9975/3 [myelodysplastic/myeloproliferative neoplasm, unclassifiable].

The term is a reportable ambiguous term per the Hematopoietic Coding Manual (Case Reportability Instructions, Rule 4). Also, the patient was treated for a myeloproliferative disorder, making this a reportable clinical diagnosis per the SEER Manual (Reportability, Pg 4, Exception 1).

Myeloproliferative disorder is synonymous with myeloproliferative disease. Myeloproliferative disease is listed as an alternate name for myelodysplastic/myeloproliferative neoplasm, unclassifiable.

20110073 MP/H Rules/Multiple primaries--Sarcoma: Does a prior clinical diagnosis of a metastatic deposit for a previously diagnosed sarcoma have priority if the diagnosis on a subsequent resection (18 months later) indicates it is also a sarcoma but does not state it represents metastasis from the original sarcoma primary? See Discussion.

1/28/08 Patient was diagnosed with spindle cell sarcoma in the right gluteus muscle. Metastatic tumors were found in a vertebral body and in the lung. Chemotherapy was started.

4/22/08 PET scan done to evaluate response to chemo. The primary tumor had increased in size. New mass in the left thigh that was highly suspicious for metastasis found. (The left thigh tumor was not accessioned at that time as it was described as a metastatic tumor.)

7/3/09 Left thigh tumor was resected and path revealed spindle cell sarcoma. There was no mention that it represented metastasis.

Does the left thigh tumor represent a new primary per rule M12? Or does the previous clinical description of the left thigh tumor representing metastasis have priority?

this is a single primary per Rule M1. According to our expert pathologist, "if multiple solid tissue tumors are present (sarcomas), then almost always there is one primary and the rest are metastases. There are infrequent occasions of multifocal liposarcoma or osteosarcoma occurring, but the patient would be treated as a patient with metastatic disease."

The steps used to arrive at this answer are:

Open the Multiple Primary and Histology Coding Rules manual. For a soft tissue primary, use one of the three formats (i.e., flowchart, matrix or text) under the Other Sites MP rules to determine the number of primaries because soft tissue primaries do not have site specific rules.

Go to the UNKNOWN IF SINGLE OR MULTIPLE TUMORS module, Rule M1.

Rule M1 states, "It is not possible to determine if there is a single tumor or multiple tumors, opt for a single tumor and abstract a single primary." Given the information from the expert pathologist, this case should be reported as a single primary applying this rule.

20081077 MP/H Rules--Ovary: How do you code histology for a diagnosis of "clear cell CA, predominately cystic." For cases diagnosed 2007 or later, assign histology code 8310 [Clear cell carcinoma]. Cystic describes the appearance of the tumor. Clear cell is the histologic type. Code clear cell carcinoma 8310/3. Rule H11 applies. Ovary N/A 2008

Reportability--Ovary: Is a Stage IIIC serous borderline tumor (micropapillary type) of the ovary diagnosed in 2003 reportable?

Serous borderline tumor of the ovary diagnosed in 2003 is not reportable to SEER. The behavior code is /1 in ICD-O-3. The high stage does not make this borderline tumor reportable. Ovary N/A 2003
20021153 Grade, Differentiation--Breast: Is "histological grade" another way of saying "tubule formation" which would result in the following case having a Bloom-Richardson (BR) score of 7 which would be coded to grade 2? See discussion. Final path diagnosis stated: Invasive ductal ca, histological grade 3/3, nuclear grade 2/3, mitotic index-moderate. Yes. Code the Grade, Differentiation field to 2 [Grade 2] for this case. This case has a BR score of 7 which converts to a grade of 2. This pathologist seems to be describing the three parts of the BR system: tubule formation, mitotic activity and nuclear grade. Breast N/A 2002
