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. |

20150062 | Grade--Bladder: How is Grade coded for the following cases diagnosed 1/1/2014 and later? See Discussion.
1) Low grade urothelial carcinoma, invasive carcinoma not identified (8120/2)
2) Papillary urothelial carcinoma, high grade, no evidence of invasion (8130/2) |
The rules for coding Bladder Grade appear to have changed over time. SPCM 2013 Appendix C instructions state that Grade should be coded to 9 for urothelial carcinoma in situ (8120/2) and to 1 or 3 for non-invasive papillary urothelial carcinoma (8130/2).
When the grade instructions were removed from Appendix C in 2014, these site specific instructions for in situ bladder cases were no longer included. Thus the two grade system, found in SPCSM 2014+ Grade/Differentiation Coding Instructions for Solid Tumors, is being used to code grade for both the in situ and invasive urothelial malignancies stated to be "low grade" (code 2) or "high grade" (code 4). See also, SINQ 20150022. Please clarify the current grade instructions for in situ and invasive urothelial carcinomas of the bladder. |
Follow the instructions in the 2014+ Grade Coding Instructions to code grade for cases diagnosed 2014 and later, http://seer.cancer.gov/tools/grade/ Instruction #4.a. states to code grade for in situ tumors when grade is specified. This instruction applies to bladder cases, as well as other in situ tumors.
1. Assign grade code 2
2. Assign grade code 4
See the note below the table in instruction #7. |

20150061 | Reportability--Vulva: Is this reportable? We have begun to see the following diagnosis on biopsies of the vulva with the statement below. The diagnosis is being given as simply VULVAR INTRAEPITHELIAL NEOPLASIA, no grade is noted. See discussion. |
The note explains: The International Society for the Study of Vulvovaginal Disease (ISSVD) in 2004 revised its classification of VIN by eliminating VIN 1 and combining VIN 2 and VIN 3 into a single category (see table below). Classification of VIN (usual type) ISSVD [International Society for the Study of Vulvovaginal Disease]1986 classification 2004 classification VIN 1 VIN2 VIN3 VIN Note: VIN 2 and VIN 3 combined into single [non-graded] category, VIN Reference: Scurry J and Wilkinson EJ. Review of terminology of precursors of vulvar squamous cell carcinoma. Journal of lower genital tract disease, 2006; 10(3): 161-169 |
Vulvar intraepithelial neoplasia with no grade specified is not reportable. Reportability instructions have not changed. See page 11 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf |

20150060 | Reportability/MP/H Rules: Where can I find documentation on how to accession malignant tumors in transplanted organs? See discussion. |
A patient was diagnosed with hepatocellular cancer (HCC) in 2010, and underwent a hepatectomy, and then received a donor liver. In 2014, HCC was discovered in the liver once again. This likely is a new primary, but there are no specific rules to cover this. There are many odd situations involving transplanted organs, many of which pose reportability and multiple primary problems. |
Accession the new tumor in the transplanted organ as you would any other new/second primary. As transplants have become more common especially for liver, lung, and kidney, we are seeing more of these types of cases. We are adding instructions to the revised MP/H rules on coding subsequent primaries when they occur in a transplanted organ. We are also looking at adding a data field that will identify cancers/tumors which arose in a transplanted organ. We feel this is important to track for analysis. Until the revised MP/H rules are implemented, we will look at adding general coding instructions to the SEER Program Manual for transplants. |

20150059 | Primary Site--Liver: What is the topography code for combined hepatocellular carcinoma/cholangiocarcinoma (M-8180/3) especially when there is no documentation that intrahepatic bile duct is the tumor site? Reports usually just indicate a liver mass(es) but since the intrahepatic ducts are within the liver, is the code C221 due to the cholangiocarcinoma component, thus making the case stageable? |
If there is no further information about where the cancer originated, assign C220. Use ICD-O-3 as the source for coding topography. The topography code associated with combined hepatocellular and cholangiocarcinoma (8180/3) is C220 when there is no other information available, according to ICD-O-3. |

20150058 | MP/H Rules/Multiple Primaries: Is this counted as one or two primaries?
Patient is diagnosed with SCC esophageal cancer. Work-up reveals a lung nodule. Lung FNA (cytology) is read by the pathologist as SCC, favor metastatic esophageal SCC. However, the managing physicians are treating the patient as two separate primaries. |
If the patient is being managed and treated as a case of primary lung cancer, report the lung diagnosis as a separate primary. |

20150057 | Reportability--Brain and CNS: Is this diagnosis reportable? If this neoplasm originated in the spinal cord, it is reportable, correct?
Specimen is described as a 'spinal cord mass.' The final diagnosis is 'fragments of adipose tissue demonstrating vascular proliferations consistent with angiolipoma. No histologic evidence of malignancy.' The microscopic description says: Sections of the spinal mass reveal bone, cartilage, fibrous tissue and adipose tissue. The adipose tissue demonstrates increased vascularity with thin walled blood vessels seen with islands of delicate fibrous stroma. The histologic findings are compatible with fragments of angiolipoma. |
The neoplasm is reportable if it originated in the spinal cord or is intradural (within the spinal dura; spinal nerve roots are intradural). If there is not enough information to determine the exact site of origin, do not report the case. |

20150055 | Multiple primaries--Heme & Lymphoid Neoplasms: Is this 2 primaries? In 2011, a patient had a spinal mass biopsied positive for DLBCL and follicular lymphoma. The heme rules make this one primary coded as DLBCL. Patient had 2 rounds of chemo, but in 2014, he had a recurrent tumor in the same location. The 2014 biopsy was follicular lymphoma. Is this a new primary -- conversion of acute to chronic after treatment? Or is it the same, since FL was diagnosed in the original specimen? |
Rule M13 applies, abstract as two primaries. Since both DLBCL and FL were present in 2011, rule M2 does not fit -- not a single histology. Rule M13 reflects the situation in this case much better: an acute neoplasm which was treated and a chronic neoplasm diagnosed later. |

20150054 | Primary Site--Skin: Should cutaneous leiomyosarcoma be coded to primary skin of site (C44_) or soft tissue (C49_)? |
Code cutanteous leiomyosarcoma to skin. Leiomyosarcoma can originate in the smooth muscle of the dermis. The WHO classification designates this as cutaneous leiomyosarcoma. The major portion of the tumor is in the dermis, although subcutaneous extension is present in some cases. |

20150052 | Primary Site--Sarcoma: What is the best primary site code for an undifferentiated sarcoma of the pulmonary artery? See discussion. |
Consolidation of the case: The operating hospital stated: SOFT TISSUE: Resection: Procedure: Radical resection Other: Pneumonectomy Tumor Site: Right pulmonary artery - They used code C383 (mediastinum NOS). The consulting hospital stated: Lung, right, pneumonectomy: High grade sarcoma consistent with intimal sarcoma; tumor involves pulmonary artery. They used code C449 (other soft tissue NOS). Would C493 (soft tissue thorax) be correct? |
Code the primary site to pulmonary artery, C493. According to the WHO classification of tumors, intimal sarcomas are malignant mesenchymal tumors arising in large blood vessels. They show mostly intraluminal growth with obstruction of the vessel. They may occur in the pulmonary vessels or, less often, in the aorta. |
