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.
Multiplicity Counter: Is there a time frame for the Multiplicity Counter or is it related to the duration for counting new tumors (i.e. 5 years for breast, etc) to capture the number of "local recurrences"?
Record the number of tumors counted as a single primary at the time the case is abstracted. Later, if additional tumors are determined to be the same primary, update this field once. Do not update the multiplicity counter more than once.
Reportability/AmbiguousTerminology: Because there is a caveat in the SEER PCM, 3rd edition to ignore adverbs such as "strongly" when assessing reportability, should a term such as "likely" cancerous be reportable given than the expression "most likely" cancerous is reportable?
"Likely cancerous" is NOT reportable.
The CoC, NPCR and SEER have agreed to a strict interpretation of the ambiguous terms list. Terms that do not appear on the list are not diagnostic of cancer.
EOD-Size of Primary Tumor--Lung: Can tumor size of 002 [Malignant cells present in bronchopulmonary secretions] be used when there is a lung mass seen but the diagnosis is from a positive bronchopulmonary secretion?
For cases diagnosed 1998-2003:
EOD-Size of Primary Tumor code 002 [Malignant cells present in bronchopulmonary secretions] is used only when there is no visible primary lung tumor and bronchopulmonary secretions are positive for lung malignancy.
Even if the diagnosis was made by cytology of broncho-pulmonary secretions, if there is a visible mass, code the size of the mass if known, code 999 if size is unknown.
Primary Site--Lymphoma: How should this field be coded when a diffuse large B-cell lymphoma is found in the femur and in the soft tissue of the anterior chest wall but all CT scans are negative for lymphadenopathy?
For cases diagnosed prior to 1/1/2010:Code the Primary Site field to C809 [Unknown primary site]. The primary site of diffuse large B cell lymphoma can be either nodal or extranodal. The case described above is likely extranodal because there is no evidence of lymph node involvement. Because the extranodal site of origin is unknown, code the Primary Site to C809.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
EOD-Extension/EOD-Lymph Nodes--Rectosigmoid: How do you code these fields for a scan-based clinically staged T3 N1 rectosigmoid primary in a patient who received chemotherapy and radiation prior to a resection that demonstrated invasion only into the muscularis and no positive lymph nodes?
For cases diagnosed 1998-2003:
Use the best information available, in this case, the clinical staging, to code EOD. Code the EOD-Extension field to 40 [Invasion through muscularis propria or muscularis, NOS] and the EOD Lymph Node field to 3 [Regional lymph node(s) NOS] because the case had a clinical stage of T3 N1. EOD is coded using the most extensive clinical or pathologic stage.
MP/H Rules/Histology--Colon: If a tubulovillous (TV) adenoma is in situ and other polyp(s) have an invasive component, does the in situ TV adenoma still have priority and should rule H18 be applied?
For cases diagnosed 2007 or later, always give precedence to coding the invasive. Rule H18 applies UNLESS the adenocarcinoma in the TV is in situ and the others are invasive. In this case, code the histology of the invasive adenocarcinoma.
This clarification will be added when the MP/H manual is revised.
Histology--Heme & Lymphoid Neoplasms: How is histology coded for a diagnosis of composite lymphoma (follicular lymphoma and small lymphocytic lymphoma, BCL-2 positive)?
Code the histology to 9823/3 [chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL)] per Rule PH15. Code the histology to the non-Hodgkin lymphoma (NHL) with the numerically highest ICD-O-3 code when two or more NHLs are present in the same present in the same lymph node(s) or lymph node region(s), tissue(s), organ(s), or bone marrow. Both follicular lymphoma [9690/3] and SLL [9823/3] are types of NHL. Therefore, the histology is coded to 9823/3.
This composite histology represents a single primary per Rule M4. The rule states to abstract a single primary when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location(s), such as the same lymph node or lymph node region(s), the same organ(s), and/or the same tissue(s).

EOD-Extension--Colon: How is this field coded for an appendical primary when the appendix has ruptured and intrapentoneal fluid is positive?
For cases diagnosed 1998-2003: Code EOD extension as 85 [Metastasis]. Positive intraperitoneal fluid is equivalent to distant metastasis (implantation) for colon, including appendix, primaries.
