20170005 | Reportability/Histology--Testis: Is neoplasm consistent with carcinoid type of monodermal teratoma reportable as a teratoma, NOS, and if yes, what is the histology code? |
Carcinoid type of monodermal teratoma or well differentiated neuroendocrine tumor (carcinoid), monodermal teratoma of the testis is reportable. Assign 8240/3 according to the WHO classification for this neoplasm. |

20170006 | Diagnostic confirmation--Heme & Lymphoid Neoplasms (Lymphoma): To code "3" in Diagnostic Confirmation, does the genetic testing need to confirm a specific histology or is it enough that is simply rules out others? See Discussion. |
For example, pathology states: Right axillary lymph node, excision: Diffuse large B-cell lymphoma (DLBCL) (see note). COMMENT: FISH studies were performed that were negative for BCL-6, c-Myc/IgH, CCND1/IgH and IgH/BCl-2 gene rearrangement, ruling out the most common forms of double-hit lymphoma. Flow cytometry studies demonstrated positivity for CD45, CD20, HLA-Dr, CD19, CD11c, CD22, CD30, CD38, CD79b, and FMC7. Low positivity was seen for CD5. No reactivity was seen for CD10, CD23, CD25, CD103 or CD123. |
Both histologic plus immunophenotyping or genetic testing should be positive to assign code 3 for Diagnostic Confirmation. The Hematopoietic and Lymphoid Neoplasm Coding Manual Diagnostic Confirmation instructions state, assign 3 for Cases positive for neoplasm being abstracted (including acceptable ambiguous terminology and provisional diagnosis) AND Immunophenotyping, genetic testing, or JAK2 is listed in the Definitive Diagnosis in the Heme DB AND a.) Confirms the neoplasm OR b.) Identifies a more specific histology (not preceded by ambiguous terminology). Because the patient was diagnosed with DLBCL by histology, and flow cytometry was positive for CD antigens (immunophenotyping) 20, 22, and 30 for DLBCL, code 3 is appropriate. |

20170036 | Grade--Prostate: How are the prostate-related fields completed when documentation in pathology reports only includes one of the new grade groups? See Discussion. |
Our pathologists have starting to use a new prostate cancer grading system that was adopted by WHO in 2016. The new grading scheme correlates with the prior Gleason grading scheme as follows: Grade Group 1 = Gleason score 6 or less Grade Group 2 = Gleason score 3+4=7 Grade Group 3 = Gleason score 4+3 = 7 Grade Group 4 = Gleason score 8 Grade Group 5 = Gleason score 9-10 Our pathologists are no longer dictating the Gleason Primary and Secondary Pattern values nor the Gleason's Score. Reverse correlation from the new grade groups to the required patterns and score are difficult with Grade Groups 2 and 3 needing to be distinguished from one another and Grade Group 5 including two unique scores. The prostate-related fields include: Collaborative Site Specific Factor 7: Gleason's Primary Pattern and Secondary Pattern Values on Needle Core Biopsy/TURP Collaborative Site Specific Factor 8: Gleason's Score On Needle Core Biopsy/TURP Collaborative Site Specific Factor 9: Gleason's Primary Pattern and Secondary Pattern Values on Prostatectomy/Autopsy Collaborative Site Specific Factor 10: Gleason's Score on Prostatectomy/Autopsy |
When all you have is the grade group, you may use the following table to convert the Prostate Grade Groups to the appropriate code for the indicated fields. Grade Group Gleason Score Gleason Pattern SSF7 SSF8 SSF9 SSF10 Grade/diff Grade Group 1 6 or less <=3+3 099 999 099 999 1 Grade Group 2 7 3+4 034 007 034 007 2 Grade Group 3 7 4+3 043 007 043 007 2 Grade Group 4 8 4+4, 3+5, 5+3 999 999 999 999 3 Grade Group 5 9-10 4+5, 5+4, 5+5 099 999 099 999 3 |

20170042 | Reportability--Heme & Lymphoid Neoplasms: Is a diagnosis of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) with large cell transformation equivalent to a diagnosis of diffuse large B-cell lymphoma (DLBCL) without mention of Richter transformation or Richter Syndrome? See Discussion. |
The patient has a history of CLL/SLL dating back to 2007, but has had progressive disease with development of a new left frontal brain tumor. The brain tumor resection proved CLL/SLL with large cell transformation, but neither the pathologist nor the managing physician called this a Richter transformation, Richter syndrome or provided a diagnosis of DLBCL. However, a large cell transformation of CLL/SLL is a Richter transformation. Can this be accessioned as a new acute neoplasm per Rule M10? |
Accession as multiple primaries according to Hematopoietic and Lymphoid Neoplasm Coding Manual Rule M10. Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) followed by CLL/SLL with large cell transformation is multiple primaries because it is a chronic neoplasm followed by an acute neoplasm, more than 21 days in this case. |

20170003 | Reportability/Histology--Brain and CNS: Is epidermoid tumor of the cerebellopontine angle (CPA) and trigeminal vesicle nerve reportable, and if so, what is the correct histology code? See discussion. |
Patient presented to hospital ED and had brain MRI that revealed 3.2 cm space occupying lesion in region of the left CPA and trigeminal vesicle nerve compatible with epidermoid tumor. |
Epidermoid tumor of the brain is not reportable. There is no ICD-O-3 code for epidermoid tumor or epidermoid cyst. This type of tumor is often referred to as a cyst because it has a thin wall that secretes a soft material into the center. |

20170046 | MP/H Rules/Histology--Brain and CNS: What is the histology code for a patient with a pathology report Final Diagnosis indicating, mucin-rich neuroepithelial neoplasm, favor low-grade? See Discussion. |
The pathologist noted this was a challenging brain neoplasm that did not easily fit into a specific WHO diagnostic classification. Multiple differential diagnoses were given including pilomyxoid astrocytoma, ganglioglioma and dysembryoplastic neuroepithelial tumor (DNET), but there were no definitive features characteristic of any of these tumors. In the Comment section following the Final Diagnosis, it further states: "In summary, the tumor appears to be a difficult to classify non-infiltrating glial/glioneuronal neoplasm without definitive high-grade features." |
Code as 9505/1, Ganglioglioma, NOS. The Multiple Primaries/Histology Rules for Benign and Borderline Intracranial and CNS Tumors Chart 1 lists several histology codes for neuronal and mixed neuronal-glial tumors. Ganglioglioma, formerly Glioneuroma that is now obstolete in ICD-O-3, is the most applicable in this situation. |

20170017 | MP/H Rules/Multiple primaries--Liver: How many primaries of the same site and histology are reported if tumors appear years apart but neither is surgically removed? See Discussion. |
Patient has an April 2009 biopsy proven diagnosis of cholangiocarcinoma with a single liver mass in segment 4 that was treated with TACE and systemic chemotherapy. The treated lesion was stated to be stable in subsequent scans performed between 2010 and late 2015. December 2015 imaging identified a new mass in the left hepatic lobe consistent with cholangiocarcinoma. Is the 2015 tumorĀ a new primary? In auditing files for expected (but not received) abstracts due from facilities, we've observed these types of cases not being consistently reported as multiple primaries. |
Abstract as a single primary. The 2009 liver tumor remained "stable" following treatment and the patient was never disease free. |

20170054 | MP/H Rules/Multiple primaries--Brain and CNS: How many primaries should be abstracted for a patient with a 2011 diagnosis of oligodendroglioma followed by biopsy of tumor which demonstrated progression in 2016 with pathology report Final Diagnosis indicating WHO grade III anaplastic astrocytoma? See Discussion. |
The clinical documentation clearly identifies residual tumor after the 2011 craniotomy. Scans demonstrated slow enlargement of the tumor over the years, which resulted in a repeat craniotomy. The pathologist noted in the diagnosis comment section of the pathology report that Is this a single primary per MP/H Rule M3 (A single tumor is always a single primary), or an additional brain malignancy per MP/H Rule M8 (Tumors with ICD-O-3 histology codes on different branches in Chart 1 or Chart 2 are multiple primaries)? |
Based on the information provided, this is a single primary. The 2011 tumor was not completely removed and progressed over the years. MP/H Rule M3 for malignant brain cancer applies. Do not change the original histology code. Use text fields to document the later histologic type of anaplastic astrocytoma, WHO grade III. |

20170029 | Reportability--Bone: Are giant cell tumors (GCT) of the bone that metastasize to the lung reportable? See Discussion. |
Patient had radical resection of pelvic giant cell tumor of bone in August 2012. Final diagnosis clarified that no features to suggest a frankly malignant giant cell tumor were identified. July 2013 left upper lobe nodules were removed and found to be consistent with multifocal metastatic lung involvement with a previous pelvic giant cell tumor of bone. However, the pathology report comment specifies there are no histological high-grade features to suggest a malignancy: While SINQ 20091087 may apply, these metastases clearly arrived in the lung by hematogenous spread. The previous SINQ note refers to a case where the implants/metastases can seed the surrounding pelvic and abdominal structures by rupture of the tumor or intraoperative tumor spillage. That type of spread is not quite the same as the current case showing tumor cells leaving the primary tumor/site and travelling through the blood to implant in the lungs. |
This case is not reportable. According to the WHO Classification of Bone Tumors, pulmonary metastases from GCTs are "very slow-growing and are thought to represent pulmonary implants that result from embolization of intravascular growths of GCT. Some of these benign pulmonary implants can regress spontaneously. A small number, however, exhibit progressive enlargement and can lead to the death of the patient." The pathologist for this case is very clear that no malignancy was found in the lung or in the bone. |

20170062 | Race, ethnicity: How do you code race for someone from New Zealand? |
I recently did a presentation on coding the data item Race. In my presentation I discussed understanding geography help code race in some circumstances. One of the slides demonstrates how large Polynesia is and what Pacific islands are found in Polynesia, such as, Tahiti, Samoa, and even Hawaii, all of which have their own codes. Someone in the audience asked "How do you code New Zealand? Upon some research, New Zealand is not listed in Appendix D of the SEER coding manual. We could code them 01-White. But research shows there is a very large indigenous population. Technically, New Zealand is located within the boundaries of Polynesia - Code 25 (Polynesian). |
If the only information you have on race is that the person is from New Zealand, code race as white. This is based on the instructions for Australia, the closest neighbor to New Zealand as no other guidance was found. |
