20140088 | Reportability--GIST: The 2014 SEER Program Coding and Staging Manual and the answer to SINQ 20100014 appear to conflict with respect to reporting GIST cases. The manual states (p.5, exception 1) that we are to accession the case if the patient is treated for cancer. However, the patient in Example #7 in the SINQ discussion is receiving chemotherapy, but is deemed not reportable. This is a problematic issue in our area, as pathologists prefer using the NCCN “Risk Stratification of Primary GIST by Mitotic Index, Size and Site” table rather than stating whether the tumor is benign or malignant. Although they tell us that moderate or high risk should receive treatment, they will not characterize them as malignant. |
Determining reportability for GIST is problematic because of the reluctance of pathologists to use the term "malignant" for GIST cases. If you can document the pathologist's terminology and case characteristics (e.g. treatment) that correspond to "malignant" for your registry as part of the registry's policies and procedures, you can report those cases as malignant.
The exception cited above in the SEER manual pertains to a clinical diagnosis with a negative pathology report. Normally, the negative pathology report would override the clinical diagnosis and the case would not be reportable. However, if the patient is treated for a malignancy in spite of the negative pathology, report the case.

20140064 | Reportability--Testis: Is a mature teratoma of the testis reportable? See discussion. |
Mature teratoma is listed as a benign neoplasm (9080/0) in the ICD-O-3. SINQ 20120085 references a NAACCR Webinar that indicated pure mature teratomas of the testis in adults are reportable. We are not aware of any further documentation of this change in reportability. When did mature teratomas of the testis for adults become reportable? What is the defined age range for "adult"? The original SINQ question above lists the 2012 SEER Manual as a Reference, however, no clarification or mention of this change in reportability was found in that manual. |
For testis, mature teratoma in an adult (post-puberty) is reportable because it is malignant (9080/3); however, mature teratoma in a child is benign (9080/0). The 2011 NAACCR webinar introduced this concept and it was documented in the 2012 SINQ question. You may use 2011 or 2012 as the date of this change. The next edition of the SEER manual will include reportability examples. |

20140010 | Multiple primaries--Heme & Lymphoid Neoplasms: Is this one primary or two? Follicular lymphoma grade 1 (9695/3) on 8/23/12 from an abdominal lymph node. On 1/6/14 an abdominal lymph node biopsy showed diffuse large b cell lymphoma arising from high grade follicle center cell lymphoma. Patient has been on observation. | 1st primary, 8/23/12: Follicular lymphoma, grade 1 2nd primary, 1/6/14: Diffuse Large B Cell Lymphoma Apply the multiple primary rules twice for this case. The 2012 diagnosis is follicular lymphoma. There are two histologies in 2014: diffuse large b cell lymphoma and follicle center cell lymphoma diagnosed at the same time in the same location. This is one primary per rule M4. Then compare the 2012 diagnosis to the 2014 diagnosis. Per the Hematopoietic Database, follicular lymphoma (all types) transforms to DLBCL. Per Rule M10, the DLBCL would be a second primary. |

20140078 | Surgery of Primary Site--Bladder: Is any mention of cautery in the gross description of pathology for a TURBT specimen sufficient to code 22 (excisional biopsy with electrocautery), or does there need to be a statement in the operative report that electrocautery was performed? See discussion. |
Often, pathology for TURBT with non-invasive papillary TCC includes a gross description with a variety of cautery descriptions. For example, "received are three cautery roughened gray-pale pink tissue fragments.” However, the operative report is documented as a "TURBT" with no further description of the procedure. |
Assign code 22 when cautery is mentioned n the gross description of pathology for a TURBT specimen. |

20150064 | Primary site--Head & Neck: When there is invasive in one subsite and in situ in another, do you code the subsite with the invasive only? Would the correct site be C320, C328, or C329? See discussion. |
LARYNGOSCOPY - ENDOLARYNGEAL EXAM WAS GROSSLY UNREMARKABLE EXCEPT THAT SHE APPEARS TO HAVE A T1A SQUAMOUS CELL CARCINOMA OF THE RIGHT TRUE VOCAL FOLD. IT EXTENDS FROM ALMOST THE ANTERIOR COMMISSURE ALL THE WAY BACK TO THE VOCAL PROCESS AND IS EXOPHYTIC IN NATURE. IT DOES NOT EXTEND INTO THE VENTRICLE OR ONTO THE FALSE VOCAL FOLD. NO SUBGLOTTIC EXTENSION IS SEEN. A. RIGHT POSTERIOR FALSE VOCAL CORD FOLD, BIOPSY: SQUAMOUS CELL CARCINOMA IN SITU. B. RIGHT POSTERIOR TRUE VOCAL CORD FOLD, BIOPSY: SQUAMOUS CELL CARCINOMA, SUSPICIOUS FOR INVASION. C. RIGHT MID TRUE VOCAL CORD, BIOPSY: SQUAMOUS CELL CARCINOMA, SUSPICIOUS FOR INVASION. D. RIGHT ANTERIOR TRUE VOCAL FOLD, BIOPSY: INVASIVE AND IN SITU SQUAMOUS CELL CARCINOMA, MODERATELY DIFFERENTIATED. |
See the Head & Neck Terms and Definitions for guidance on coding the primary site, pages 17-18, http://seer.cancer.gov/tools/mphrules/mphrules_definitions.pdf
Based on the information provided, use the statement from the endoscopy report and assign primary site to right true vocal fold [cord], C320. |

20150031 | MP/H Rules/Multiple primaries--Colon: This is an unusual case of multifocal colon cancer. The case is staged pT4b,N1b. Per our MP rules, this will be 4 separate primaries. Would this be an exception to the rules; if not now, possibly in future versions of the MP rules for colon cancer? See discussion. |
The path report reads: COMMENT: There is multifocal involvement throughout both bowel segments which combined represent a subtotal colectomy procedure. There are at least 11 tumors, all of which are histologically similar. Given the unusual gross appearance, a representative portion of the largest mass (hepatic flexure) was forwarded to _____ for flow cytometric evaluation. There is chronic active colitis in the background suggestive of idiopathic inflammatory bowel disease, specifically ulcerative colitis. However, no dysplasia is seen in multiple random sections of grossly benign large bowel. ADDENDUM from expert gastroenterologist: The carcinomas are poorly differentiated without specific histologic features but are consistent with colon primaries. These findings are consistent with an MLH1-deficient carcinoma. Given the background chronic active colitis consistent with ulcerative colitis, this likely represents colitis-associated neoplasia which can be associated with multifocality. |
This unusual case of multifocal colon cancer is not an exception to the MP/H rules currently.
The current WHO classification for colon tumors mentions ulcerative colitis (UC) associated colorectal cancers and states they are often multiple. This will be discussed for the next version of the MP/H rules. |

20150065 | First course treatment/Chemotherapy/Drug category: Instructions in SEER*Rx state that Ibrance should be coded as chemotherapy. They also state that it is an endocrine-based therapy. Local physicians refer to Ibrance as hormone therapy. Please clarify. |
For cancer registry data collection, follow the instructions in SEER*Rx. It is important for all data collection to be consistent for reporting of cancer information.
Per the FDA: Ibrance is a chemotheraputic agent which was approved for use WITH Letrozole. Letrozole is a hormonal drug which may be why the physicians are stating the patient is receiving hormones. Ibrance should not be given alone to treat breast cancer. This drug will not be changing categories in SEER*Rx. |

20150034 | MP/H/Histology/neuroendocrine : How should the following histologies with neuroendocrine differentiation be coded?
1. Bladder - Invasive urothelial carcinoma with neuroendocrine differentiation
2. Nasopharnyx - Undifferentiated nonkeratinizing nasopharyngeal carcinoma with neuroendocrine differentiation
3. Ductal carcinoma in situ (with neuroendocrine features) cribriform and solid patterns
See discussion. |
We are starting to see more specific histologies with neuroendocrine differentiation. How are we to deal with these histologies and will this be addressed in the revised MP/H rules? |
The term neuroendocrine is often included with other histologies and usually means that neuroendocrine cells are present but not neuroendocrine tumor.
1. If the neuroendocrine cells are stated to be either small cell or large cell, code that histology; however, neuroendocrine, NOS mixed with urothelial does not have an applicable mixed code. Code histology to 8120.
2. Code histology to squamous cell carcinoma, nonkeratinizing, NOS (8072/3). The neuroendocrine component is not specified as either small cell or large cell.
3. Code to 8523/2 per MP/H Rule H6 as intraductal mixed with other types of carcinoma present.
Note that while neuroendocrine differentiation can be identified, it seems to have no prognostic implications. We have consulted with our site specific Subject Matter Experts on how best to capture neuroendocrine, NOS when combined with other histologies. These instructions will be included in the revision of the MP/H rules including the wording of MP/H breast rule H6. |

20150015 | Primary Site--Testis: What is the prmary site for a 38 y/o male diagnosed with testicular cancer in a formerly undescended testis that was treated with orchiopexy at age 10-11? See discussion. |
Should it be coded to where the testis was physically at the time of diagnosis (C621), or should it be coded to C620 to reflect the increased risk for developing malignancy in an undescended testis? |
Code the primary site C621 (descended testis). The primary site of this neoplasm is a scrotal (descended) testis. The history of orchiopexy can be noted in a text field, but does not change the primary site in this case. |

20150048 | Reportability--Skin: Is low grade trichoblastic carcinoma, with a small focus of high grade carcinoma of the scalp reportable? See discussion. |
Pathology report states: the individual nodules of trichoblastic cells resemble those seen in trichoblastoma, but the lesion is very poorly circumscribed with an infiltrative border that extends into the subcutis. the lesion may behave in a locally aggressive fashion, and should be completely removed. High grade trichoblastic carcinomas can metastasize. |
Trichoblastic carcinoma of the skin is not reportable. The WHO classification lists trichoblastic carcinoma as a synonym for basal cell carcinoma, 8090/3. Basal cell carcinoma of the skin is not reportable. See page 11 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf. |
