20150022 | Grade--Bladder: Do you use the grade stated on the pathology report for coding the grade/differentiation field for bladder and renal pelvis field? See discussion. |
Please confirm correct coding for grade for papillary urothelial carcinoma of the bladder/renal pelvis and urothelial carcinoma of the bladder/renal pelvis. SEER Manual 2014 and 2015 state: "Do not use these tables to code grade for any other groups including WHO (CNS tumors), WHO/ISUP (bladder, renal pelvis), or FIGO (female gynecologic sites) grades." They also state "In transitional cell carcinoma for bladder, the terminology high grade TCC and low grade TCC are coded in the two-grade system" in the Grade section. These statements are not included in SEER Manuals prior to 2014. |
Use the grade stated on the pathology report to code grade/differentiation for bladder and renal pelvis field unless the grade is stated to be WHO/ISUP grade. |

20150026 | First course treatment--Breast: When Lupron is given as cancer-directed treatment for metastatic breast cancer, should it be coded as Hormone Therapy or Other Therapy? See Discussion. |
Per the SEER*Rx Database, Lupron is coded as Other Therapy for breast cancer until such time that it receives FDA approval. However, SINQ 20021042 states Lupron should be coded as Hormone Therapy when given as cancer-directed therapy. These two sources contradict each other.
Information regarding hormone therapy for breast cancer in both the SEER*Rx Database and the National Cancer Institute's Cancer Topics website (http://www.cancer.gov/types/breast/breast-hormone-therapy-fact-sheet) seem to indicate that the SINQ answer is the correct choice. The NCI Cancer Topics website states that Lupron acts to block ovarian function and is an example of an ovarian suppression drug that has been approved by the FDA. The SEER*Rx Database Remarks section states that a combination of letrozole and leuprolide (Lupron) "is considered standard treatment for metastatic breast cancer and is sometimes used for treatment of early stage breast cancer." But the Remarks go on to state that Lupron should be coded as Other Therapy until it receives FDA approval.
It is unclear how to code Lupron for breast cancers when the NCI website indicates that it is standard treatment while the SEER*Rx Database states both that it is and that it is not standard treatment. |
Code Lupron given for breast cancer in the "Other" treatment field using code 6 (other-unproven). Lupron is still not an approved hormone treatment for breast cancer and should not be coded in the hormone field.

20150020 | Reportability/Primary site--Skin: Is a basal cell carcinoma of the lip "ever" reportable and if so, what would need to be documented or seen? See discussion. |
There is a 1988 case that hit the SEER edits for other reasons but not because of that site/histo combination (C000 and 8090/3); however, there is no text. Per a Dataminer query, there are 42 cases in the state database with C000-C009 and 8090. On review, a few did have a mention of the word "upper lip/mucosa" in the PE text or OP findings (not path because a lot of these are removed in the MD office and we don't see the path report). Other times, there is no mention but the abstractor used the C00 codes instead of C44 so the cases get through. SINQ #20031110 addresses this in relation to C000, Lip, NOS but we want to know if this answer meant you would never report a basal carcinoma lip case period (even if there is a mention of mucosa or any mention of mucosa in the path report). Are there any exceptions? It seems if you would never report a basal lip carcinoma, then SEER would block those cases from being reported/submitted and the wording would be stronger in the SEER manual. Right now the reportability only addresses if someone codes C44 but if someone decides to use C00 codes then it is allowed. Under Primary Site, there is even a listing under 12 for "absence of any additional information" and lists "Colored / lipstick portion of upper lip" as code C000. |
BCC of lip C00_ is rare and requires a statement that the tumor is on the vermilion border (rather than skin) to be coded C00_ and to be reported. Our expert pathologist consultant refers to an article in the Am Acad Dermatol 2004; 50(3): 384-387. |

20150007 | MP/H Rules/Histology: What is the proper histology code -- mucin producing adenocarcinoma or cholangiocarcinoma for the following case? See discussion. |
4/10/13 Partial hepatectomy: well differentiated mucin producing adenoca involve right and left hepatic ducts, common hepatic duct & common bile duct. Invasion beyond wall of bile duct. CT Scan after 1st surgery shows residual neoplasm cannot be excluded
7/31/13 Left lateral segmentectomy: residual well differentiated cholangiiocarcinoma involving connective tissue surrounding major bile ducts. Per medical director, histolgically code to cholangiocarcinoma.
Primary site: Extra hepatic bile duct. Chemo (5FU, Leucovorin, Oxaliplatin) was started 5/1.
|
Code the histology as well differentiated mucin producing adenoca based on the 4/10/13 pathology report.
Code histology from the pathology report of the procedure which removed the most tumor tissue -- this is from the MP/H general instructions for coding histology. We are assuming that the partial hepatectomy removed the most tumor tissue in this case.
Per WHO, mucin producing adenoca is a variant of cholangiocarcioma. |

20150046 | Reportability--Appendix: Is the appendix the primary site for a low grade mucinous appendiceal neoplasm (LAMN) with diffuse peritoneal dissemination? See discussion. |
Patient had an appendectomy revealing a low grade mucinous appendiceal neoplasm (LAMN) with diffuse peritoneal dissemination. Patient now with cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC), which revealed metastatic disease in the abdomen, omentum, pelvic peritoneum, peri-cecal, and gallbladder. |
For cases diagnosed prior to 1/1/2022 Low-grade appendiceal mucinous neoplasm (LAMN) is not reportable, even when it spreads within the peritoneal cavity, according to our expert pathologist consultant. Peritoneal spread of this /1 neoplasm does not indicate malignancy. It is still /1 when there is spread of LAMN in the peritoneal cavity. |

20150042 | Surgery of Primary Site--Breast: Is the surgery code 42 or 52? Does it matter that the procedure states no axillary LN, but the pathology found 2 additional LN? See discussion.
|
Procedure stated = Bilateral skin-sparing mastectomies, left axillary sentinel lymph node biopsy. On the pathology report it indicates two additional lymph nodes were removed that were not SLN. The axillary aspect measures 2 x 2 x 1 cm. Two lymph nodes are identified ranging from 0.5 up to 1 cm. The lymph nodes are bisected and entirely submitted. Final Diagnosis Left breast, mastectomy including nipple: no residual carcinoma; FINAL DIAGNOSIS for LN = Lymph nodes, left axillary sentinel #1; excision: Two lymph nodes examined - negative for tumor (0/2); Two lymph nodes - negative for tumor (0/2) |
Assign surgery of primary site code 42. It is possible to obtain lymph nodes in a mastectomy specimen without an axillary dissection. Remember to capture the excised lymph nodes in the scope of lymph node surgery field. |

20150039 | Reportability--Skin: Is this reportable? If so, what is the correct histology code? The pathology report says, " bx of 0.7 x 0.5 cm gray-pink papule on tan-pink skin of left inferior centra malar cheek revealed invasive SCC of skin, signet ring cell type, invading papillary dermis; LVI neg; "findings are diag of SCC exhibiting the rare signet ring histologic subtype"; deep margin positive for tumor but peripheral margins clear;". |
SCC of skin, signet ring cell type, is not reportable to SEER. SCC's of skin classifiable to 8050-8084 are not reportable to SEER. See page 11 in the SEER manual, http://seer.cancer.gov/manuals/2015/SPCSM_2015_maindoc.pdf
Signet ring is a rare histological variant of SCC and is coded to 8070/3 according to the WHO classification for skin tumors. |

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. |

20150019 | Reportability/Histology--Pancreas: Is well-differentiated neuroendocrine tumor (M8240/3) as stated on a pathology report reportable or can the clinical information be used as an adjunct to the path report, which further states the specific type of neuroendocrine tumor is an Insulinoma, therefore, NOT reportable (M8151/0)? See discussion. |
The diagnosis date is 2/24/14. The pathology report of the pancreas shows: Well-differentiated neuroendocrine tumor (NET), low grade (WHO G1 of 3). Addendum: Ki-67 confirms low grade of pancreatic endocrine tumor (less than 2% Ki-67/MIB-1 index). Chromogranin confirms the endocrine nature of the tumor. The Pre and Post Op Diagnosis is pancreatic neuroendocrine tumor consistent with insulinoma. AJCC Stage as noted on path report: pT1, pNX, pM.
The physician states: The patient has a well-documented insulinoma. Biochemistries confirmed the disease and it is localized in the tail of the pancreas.
The issue with NETs is that pathology report reflects what is seen or what is quantified under the microscope; often, there is a specimen without the accompanying medical history and clinical signs. Many of these NETs are specified on the basis of the hormone, as usually measured in the blood, that is overproduced, something not seen microscopically. All of the islet cell tumors are NETs. The insulinoma in the example above is a well-differentiated NET that is causing insulin to be over-produced. Thus, the diagnoses are not discordant; insulinoma is a more specific NET. |
When the pathology diagnosis is a neuroendocrine tumor (/3) and the clinical diagnosis is an insulinoma (/0), report the case. Although ICD-O-3 classifies insulinoma as /0, the most recent WHO classification lists it as /3. The pathologist and physicians for this case are likely guided by the WHO classification and as a result, would view both the NET diagnosis and the insulinoma diagnosis as malignant. You could report this case as 8240/3 or 8151/3. |

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. |
