20160030 | Reportability--Carcinoid: Is a diagnosis of carcinoid heart disease, based solely on clinical information and no pathology, reportable? |
Carcinoid heart disease is not reportable but this diagnosis indicates that the patient likely has a carcinoid tumor which may be reportable. Obtain further information. |

20160052 | Summary Stage 2000--Lymphoma: How is SEER SS2000 coded for an ocular adnexal lymphoma when it extends from the primary site to adjacent sites that are still orbital structures? See Discussion. |
In this case, the lymphoma arose in the posterior orbit and the primary site was coded as C696 (orbit, NOS). The mass directly extended to at least one "adjacent" site, the lacrimal gland. Should SS2000 be coded to 1 (localized) or 5 (regional, NOS) when an ocular adnexal lymphoma arises in the posterior orbit and extends to involve the lacrimal gland? Although both the posterior orbit and the lacrimal gland are parts of the orbit, they have separate ICD-O-3 topography codes. Should extension to multiple sites within the orbit be classified as localized disease?
The issue is what constitutes "adjacent" structures for a tumor that arises in the orbit. In an article published by the Indian Journal of Opthamology it states, "According to the Ann-Arbor staging system, lymphoma confined to the orbit is designated as Stage I, involvement of adjacent structures (sinuses, tonsil and nose) makes it Stage II." Does SEER agree with this definition of "adjacent" structures? Or are the lacrimal gland, ciliary body, retina, conjunctiva and/or choroid "adjacent" structures for a lymphoma stated to arise in the posterior orbit? |
Assign SEER SS2000 code 5 (Regional, NOS) for a lymphoma of orbit extending to lacrimal gland. In SEER SS2000, this is Stage IIE: Direct extension to adjacent organs or tissues. |

20160001 | MP/H Rules/Multiple primaries/Histology--Rectum: How many primaries does this person have and what is the correct histology? See discussion. |
Rectal polyp excised in June, 2012, found to have adenocarcinoma in situ in a tubulovillous adenoma. Additional colorectal biopsies in November; all were negative. Another rectal polyp removed in December 2012 showing a tubulovillous adenoma with focal carcinoma in situ. Then, in February, 2013 another rectal polyp removed. This was diagnosed as mod. diff. adenocarcinoma with mucinous features, infiltrating into submucosa, seen in a background of tubulovillous adenoma. Surgical margins free (mucin %=40%). Finally, in May, 2013, a low anterior resection with no residual adenocarcinoma.
This appears to be adenocarcinoma in multiple adenomatous polyps (8221/3), although the final path from May 2013 described one benign polyp and said, 'no other masses, suspicious lesions or polyps are identified.' Going through the MP/H rules, both M13 and M14 result in this being a single primary, and come before the rule about an invasive tumor following an in situ tumor more than 60 days later is a new primary. The original abstract was coded C209 and 8263/2. If this is a single primary, should it be changed to 8221 with a behavior code of 3? Is this scenario another example of when to change the original diagnosis based on subsequent information? |
Abstract a single primary and code as 8263/3. Other Sites rule M14 applies. The histology code is 8263/3 based on rules H28 and H12. Apply H28 first, make a second pass through the H rules and apply H12. See slide 18 in the "Beyond the Basics" presentation for applicable instructions on a similar situation, http://seer.cancer.gov/tools/mphrules/training_adv/SEER_MPH_Gen_Instruc_06152007.pdf
This case is an example of the need to update the original abstract based on more complete, subsequent, information. |

20160041 | First course treatment/Surgery of Primary Site--Skin: How are Surgery of Primary Site and Surgical Procedure of Other Site coded for an eyelid skin primary diagnosed by punch biopsy and treated with an orbital exenteration? See Discussion. |
Unlike most other sites, there is no specific code for a radical surgical procedure of a skin primary. In this case, the patient was diagnosed with a sebaceous cell carcinoma of the lower eyelid skin by punch biopsy. The tumor was large and an orbital exenteration was planned. Despite the extensive surgery performed, skin margins were less than 1 cm. Is an orbital exenteration a "major amputation" (code 60) in this case? Given that the margins were not greater than 1 cm, codes 45 - 47 (which includes a minor (local) amputation) don't seem to apply. However, if this procedure cannot be classified as "minor amputation" then doesn't it seem overkill to refer to the procedure as a "major amputation"?
An alternative would be to code Surgery of Primary Site to 32 for the skin resection (punch biopsy followed by a gross excision of the lesion, margins less than 1 cm) and code Surgical Procedure of Other Site to 2 (non-primary surgical procedure to other regional sites) to record the removal of the globe and orbit as part of the orbital exenteration. Which is correct? |
There is a similar question in the FORDS forum of the CoC CAnswer Forum. CoC is the curator for the surgery codes.
Surgical Procedure to Primary Site - Gross excision of the lesion, code in 30s series Surgical Procedure to Other Site (removal of eye) - code 4

20160044 | MP/H Rules/Histology--Sarcoma: What is the appropriate histology code for a final diagnosis of undifferentiated pleomorphic sarcoma and/or pleomorphic sarcoma, undifferentiated? See Discussion. |
Does the Other Sites MP/H Rule H17 apply in this case, which results in coding the higher histology 8805/3 (undifferentiated sarcoma)? Or does the "undifferentiated" statement only refer to grade, which results in coding histology to 8802/3 (pleomorphic sarcoma)? |
Assign 8802/34 to pleomorphic cell sarcoma/undifferentiated pleomorphic sarcoma. Pleomorphic is more important than undifferentiated when choosing the histology code in this case. Undifferentiated can be captured in the grade code. |

20160038 | Birthplace/Place of birth, country: For patients originally born in a country that is currently listed as "historic only", where the original birth country now has a one-to-many relationship with the current country, how should the reported original birthplace be coded? (Example: Yugoslavia) |
Assign code for Europe, NOS (ZZE) for Yugoslavia, NOS, without further information. |

20160067 | MP/H Rules/Histology--Skin: What histology code and MP/H Rule apply to a skin primary with the final diagnosis, ? See Discussion. |
The patient had an upper arm shave biopsy with final diagnosis of basaloid carcinoma with squamous and neuroendocrine differentiation. The pathologist also comments: Further resection was negative for residual malignancy.
Would SINQ 20150033 apply, thus resulting in final histology of carcinoma with neuroendocrine carcinoma (8574/3)? |
Assign 8574/3 according to Other Sites rule H17 for basaloid carcinoma with squamous and neuroendocrine differentiation.
There is no combination code that includes basal cell, squamous, and neuroendocrine. We can combine basal cell with squamous, 8094/3, or carcinoma with neuoendocrine differentiation, 8574/3. Rule H17 directs us to assign the higher code, 8574/3. |

20160073 | MP/H Rules/Multiple primaries/Histology: What histology and how many primaries are coded for a mixed germ cell tumor with a somatic type malignancy (rhabdomysarcoma) if the patient was diagnosed with seminoma of the testis in 2009 followed by a 2015 metastatic germ cell tumor in a retroperitoneal lymph node, stated to be a recurrence of the testicular cancer? See Discussion. |
In September 2009 the patient was diagnosed with seminoma, classical type, following an orchiectomy. Testicular mass recurrence in 2014 was treated with chemotherapy. Then in April 2015 a retroperitoneal dissection of a peri-aortic LN was positive for mixed germ cell tumor with somatic type malignancy (rhabdomyosarcoma) involving 1/11 nodes. Path Comment: major component of tumor is teratoma, rhabdomyosarcoma represents <5% of mass. Now in October 2016, the patient has a retroperitoneal mass biopsy positive for spindle cell sarcoma with rhabdomyosarcomatous differentiation. The comment section of the pathology report states, "Given the history of a germ cell tumor w/ rhadbomosarcomatous component, the findings are consistent with a recurrence of rhabdomyosarcomatous component of germ cell tumor." Can a seminoma transform to a mixed germ cell tumor with a somatic type malignancy (see SINQ 20140082 - testicular teratoma with somatic type malignancy)? |
According to our expert pathologist consultant, yes, seminoma could transform to a mixed germ cell tumor with a somatic type malignancy. He advises us to code this case as 9061/3. From our expert pathologist consultant: This occurs as "reprogramming" of the initial germ cell tumor/seminoma cell. The process is not understood, but genetic studies support this progression concept. Most often the next step is teratoma. It is out of the teratoma that the somatic malignancy usually comes. I do wonder about the possibility that this was really an embryonal carcinoma which resembles a seminoma - occasionally this can be a difficult separation. I wonder if they radiated the scrotum following the orchiectomy, also, given the scrotal recurrence. |

20160053 | MP/H Rules/Histology: How is the histology coded for an invasive adenocarcinoma arising in a papilloma with high-grade dysplasia? See Discussion. |
Patient has a perihilar bile duct primary with a microscopic focus of invasive moderately differentiated adenocarcinoma arising in a large papilloma. The MP/H Rules do not address adenocarcinomas arising in a papilloma, only adenocarcinomas arising in an adenoma (or polyp). Should the histology be coded as 8140 for the invasive adenocarcinoma component? Or should the matrix principle be applied and the histology coded as a malignant glandular papilloma (8260/3)? |
Assign 8503/3 for invasive adenocarcinoma arising in a papilloma with high-grade dysplasia, perihilar bile duct primary. Neither ICD-O-3 nor the WHO classification have a code for this specific histology; however, our expert pathologist consultant states 8503/3 is the best available choice based on pages 264 and 273 in the WHO Digestive system classification. |

20160079 | First course treatment/Chemotherapy: Is metronomic chemotherapy coded as chemotherapy? |
Code metronomic chemotherapy as chemotherapy. Metronomic chemotherapy, also referred to as low-dose metronomic (LDM) chemotherapy, is an emerging cancer treatment approach which administers relatively low doses of traditional chemotherapy drugs over a long period of time and without ‘breaks’ in treatment. By using lower doses this method of treatment minimizes the side effects of traditional chemotherapy. |
