20150018 | First course of treatment--Immunotherapy: Should Rituxan be coded to immunotherapy? See discussion. |
Is the instruction under #4.b. on page 114 of the 2014 SEER Program Coding and Staging Manual incorrect? It says to code Rituxan as chemotherapy. |
Rituxan changed categories from chemotherapy to a biologic therapy/Immunotherapy agent effective with cases diagnosed January 1, 2013. See page 150 or page 164 in the 2015 SEER manual. The instruction in the 2014 SEER manual was incorrect regarding Rituxan. |

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. |

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. |

20150027 | Date of diagnosis--Diagnostic confirmation: How are the diagnosis date and diagnostic confirmation coded when the pathology (needle biopsy followed by resection) reports GIST, NOS and the physician subsequently states this is a malignant GIST and treats the patient for a malignancy? See Discussion. |
Pathologists rarely diagnose a GIST as a malignant tumor. Per the AJCC, GISTs encompass a continuum in terms of biologic potential, with larger more mitotically active tumors landing on the "histologically sarcomatous" or malignant end of the spectrum. Because the pathologists generally do not categorize these tumors as benign or malignant, the judgement is typically made by the clinician in light of all the clinical and pathologic findings. Unless there are obvious distant metastases, the clinician usually decides whether a GIST is malignant and treats the patient as such.
In the case above, the patient underwent a gastric biopsy on 04/10/2014 that showed GIST. The subsequent resection on 04/12/2014 showed a 4.5 cm GIST, spindle cell type with 6 mitoses/5 square mm. The resection pathology report does not indicate the GIST is malignant, but does identify a large tumor with mitotic activity. After reviewing the evidence in this case, the clinician calls this a malignant GIST on 04/29/2014 and starts the patient on Gleevec.
Although neither the biopsy nor the resection call this a malignant tumor, should the date the GIST was first diagnosed (biopsy on 04/10/2014) be used to code the diagnosis date, since this is the date the tumor (ultimately felt to be malignant) was diagnosed? If the diagnosis date is coded as the date malignant GIST was first mentioned (04/29/2014), this would exclude surgery as treatment for this tumor.
Would this be a histologic diagnosis because the tumor was histologically confirmed to be GIST? Or must this be a clinical diagnosis because the diagnosis of malignancy was only made clinically (by the clinician's review of the clinical and pathologic findings)? |
Code the diagnosis date for this case as 04/10/2014. Code the diagnostic confirmation as histologically confirmed. The clinician is using all of the information available to determine the diagnosis, including the biopsy and resection. |

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. |

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. |

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. |

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. |

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. |

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. |
