20130104 | Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a diagnosis of intrasinusoidal diffuse large B-cell lymphoma involving lymph nodes, the liver and the bone marrow? See Discussion. | Intrasinusoidal DLBCL was diagnosed by liver biopsy. The bone marrow was involved based on abnormal cytogenetic findings. Per a physician's note, a PTA CT Abd/Pelvis showed hepatosplenomegaly and mild periportal/peripancreatic lymphadenopathy. A GI physician stated the lymphoma involves the veins of the liver.
Should the primary site be coded to the liver [C220] and the histology to 9680/3 [DLBCL]? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the primary site to the intra-abdominal lymph nodes [C772] per Rule PH20.
Code the primary site to the specific lymph node region when multiple lymph node chains within the same region as defined by the ICD-O-3 are involved. Periportal and peripancreatic nodes are both intra-abdominal region nodes.
Based on the information provided, there is involvement of lymph nodes, the liver, spleen and bone marrow, but no other documentation of the primary site. Given that a primary lymphoma of the liver is very rare; it is unlikely that this lymphoma arose from the liver. Involvement of the liver and spleen is very common for patients with lymphoma. The involvement of the liver, spleen and bone marrow is coded in the CS fields as Stage IV involvement.

20031120 | Primary site: How is this field coded for a malignant spindle cell neoplasm in a subcutaneous mass of the right knee? See Description. |
The pathology report says: Right knee tumor: A. discrete subcutaneous mass 3.5x5.2x1.4 cm malignant spindle cell neoplasm (see Comment) B. A focus of subcutaneous malignant neoplasm is identified in the superior resection margin. C.All other margins are clear. The comment mentions that the specimen has been sent to Mayo Clinic and the Mayo clinic consult says, "we still believe that the diagnosis of spindle cell carcinoma is correct. Obviously the differential diagnosis involves melanoma and sarcoma also. The results of the immunoperoxidase stains strongly support the prior diagnosis of a carcinoma." |
Code the site to C49.2 [Connective, subcutaneous and other soft tissues of lower limb and hip]. The site is a subcutaneous mass. C49 with 8032/3 will not be impossible following the next updates to the SEER edits. |

20140008 | Primary site: If text supports a pancreatobiliary primary with no other information what primary site code would be assigned? C249 biliary tract NOS, or C269 GI tract nos, or C809 unknown? | Assign C269 in the absence of any additional information. | N/A | Primary site | 2014 | |

20130151 | Primary site--Heme & Lymphoid Neoplasms: What is the primary site when a splenectomy shows "T large granular lymphocytic leukemia" and the peripheral blood flow cytometry is negative? See Discussion. | The physician note states there is no evidence of leukemia on peripheral blood. The disease is localized to the spleen. Is the primary site coded to the bone marrow [C421] or can it be coded to the spleen [C422]? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the primary site to C421 [bone marrow]. Leukemias are coded to the bone marrow per the Heme DB.

20100112 | Primary site--Heme & Lymphoid Neoplasms: Is C448 [overlapping lesion of skin] or C449 [skin, NOS] the appropriate site code for a 2008 diagnosis of mycosis fungoides involving over 40 percent of the skin surface, including both upper and lower extremities and trunk? | Code the primary site to C449 [skin, NOS]. The code C448 should be used when there is a single overlapping lesion that includes all the disease. The patient has extensive skin coverage involving multiple skin subsites (upper and lower extremities and the trunk), but it is unlikely there is ONE plaque (one lesion) overlapping all these different skin subsites. The disease has more likely presented as multiple plaques (lesions) in these different areas. | Heme & Lymphoid Neoplasms | Primary site | 2010 | |

20021078 | Primary Site: How do you code the primary site when the tumor is identified in a bladder that was reconstructed using a stomach augmentation procedure and the pathology report states, "Bladder/prostate: adenocarcinoma arising within gastric mucosa, with the following features: highly infiltrative through the bladder wall"? | Code the Primary Site field to bladder [C67.9]. Code the location of the tumor as the primary site. | N/A | Primary site | 2002 | |

20051010 | Primary Site/Priorities--Breast: When there are conflicting references to subsite in different reports, which report has priority? See Discussion. | The clinical site of the palpable mass is outer quadrant. The pathologist states inflammatory breast cancer located in the central breast. Should the site be coded to C501 for central breast, C509 for inflammatory breast ca, or C508 for outer quadrant? | Code the breast subsite from the pathology report (C501, central). The priority order for coding subsite from conflicting reports is 1. Pathology report 2. Operative report 3. Physical examination 4. Mammogram, ultrasound The primary site of inflammatory breast carcinoma is coded to C509 when there is no palpable tumor. |

20081002 | Primary site: What is the correct primary site code for angiosarcoma of the spleen with mets to bone marrow C42.2 vs C49x? See Discussion. | Robbins Pathology states the following about liver angiosarcomas: Hepatic angiosarcomas are rare but of interest because they are associated with distinct carcinogens, including arsenic (exposure to arsenical pesticides), Thorocast (a radioactive contrast medium previously widely used in radiology), and polyvinyl chloride (PVC) (widely used in plastics). The increased frequency of angiosarcomas among works in the PVC industry is one of the truly well-documented instances of chemical carcinogenesis in humans. With all these agents, there is a very long latent period of many years between exposure and the development of tumors.
Could the same apply to the spleen? |
Code C422 [Spleen] as the primary site for angiosarcoma of spleen with metastasis to bone marrow. | N/A | Primary site | 2008 |

20210068 | Mets at Diagnosis Fields/Primary Site--Lymph Nodes: How are the Mets at Diagnosis fields coded when the metastatic adenocarcinoma involves only one lymph node area and the primary site is unknown? See Discussion. |
In 2018, patient has lymph node metastasis confined to left retroperitoneal area; core biopsy was done which showed metastatic adenocarcinoma, unknown primary site. There are no other sites of disease found. Should I code Mets at Diagnosis--Distant Lymph Node(s) as 1, and the others such as bone and lung as 0? |
In a situation like this with one area of metastatic involvement and an unknown primary, if there is no further information, we advise that the metastasis are "regional" until/unless proven otherwise. With this in mind, code the Mets at Diagnosis fields as 0, including the Mets at Diagnosis--Distant Lymph Node(s). This case should continue to be worked up to identify the primary site. If a primary site is identified later, update the abstract accordingly. In the meantime, use text fields to describe the situation. |

20120037 | Primary site--Heme & Lymphoid Neoplasms: What is the primary site code for a primary effusion lymphoma if the patient has multiple regions that are positive (e.g., pleural and pericardial effusion and the pleural fluid) for lymphoma? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per the Abstractor Notes in the Heme DB, primary effusion lymphoma (PEL) is unusual in that the majority of cases arise in body cavities, such as the pleural, pericardial, and peritoneal cavities. Because there are no ICD-O-3 codes for the pleural space, pericardium, or peritoneal cavity, code the primary site to pleura C384 when the neoplasm arises in the pleural cavity, to pericardium C380 when it occurs in the pericardium, and to peritoneal cavity C482 when it occurs in the peritoneum.
Typically only one body cavity is involved. However, if multiple regions are positive for PEL as in this case, code the primary site to C809 per Rule PH27. Rule PH27 indicates one is to code the to primary site C809 when there is no evidence of lymphoma in lymph nodes AND the physician in the medical record that he/she that the lymphoma in an
