20021089 | Primary Site--Ovary/Peritoneum: When ovaries are not found on a resection or if the ovaries removed are negative for malignancy, but the clinician refers to the adenocarcinoma in the pelvis as being an "ovarian" primary, should the primary site be coded as ovary, pelvic peritoneum or unknown? See discussion. | Example 1: Patient has a history of a BSO without an indication that it was done for malignancy. Pt has a resection. No ovarian tissue found. No site is mentioned in the pathology report. The clinician refers to the diagnosis of adenocarcinoma in the pelvis as an "ovarian" primary.
Example 2: Resected ovaries are negative. No specific site of origin is mentioned in the path. Again, the clinician refers to the diagnosis of adenocarcinoma in the pelvis as an "ovarian" primary. |
Code the Primary Site for both examples to peritoneum [C48.2]. When the physician refers to a case as "ovarian" even though the ovaries are negative or when the histology is an ovarian histology, such as papillary serous ca, the primary site should be coded to the peritoneum. Code the Primary Site to where it appears the disease is arising. | 2002 |

20021133 | First Course Treatment--All Sites: The patient has undergone part of the planned first course of treatment when a metastatic deposit is identified. If the patient continues with the planned first course of treatment, should the modalities of treatment given after the metastatic deposit is discovered be included in the coding of the first course of cancer-directed treatment fields? |
Yes, those modalities should be counted as part of first course of cancer-directed treatment if the patient continues with the planned first course. For example, if patient has the originally planned type of surgery, radiation, or drug protocol, then code the given treatment as first course. Caution: It is not a change in the treatment plan if the drugs are changed but the action of the drugs remains the same. This is still first course. However, if the treatment is changed from a chemotherapy drug to a hormonal drug following the discovery of the mets, do not code the hormonal therapy as first course. |

20021112 | Multiple Primaries/Histology--Hematopoietic, NOS: The subsequent primary table for 2001 and later indicates that 9863/3 [acute myelogenous leukemia (AML)] followed by 9980/3 [refractory anemia (RAEB)] is a new primary, but 9989/3 [myelodysplastic syndrome, NOS (MDS)] is not. Is the case below two primaries? See discussion. | Bone marrow bx states: The morphologic blast count of 7% exceeds 5%, traditionally used to define relapse in the setting of acute leukemia. Given the clinical hx that the pt's peripheral blood counts had initially normalized after induction therapy, the recent fall in counts is worrisome for the possibility of early relapse. Alternatively, therapy may have simply reverted the pt's marrow from AML to a precursor myelodysplastic syndrome (such as RAEB given the blast count) from which the AML arose, with the falling counts being progression of the underlying MDS. The identification of significant dysplasia in the bone marrow at the time of diagnosis would tend to support the possibility of an underlying MDS. Clinically, it is unlikely to make a difference whether one regards the present situation as early relapse or progression of an underlying MDS. The final clinical diagnosis is "Myelodysplasia, classified as RAEB." | For cases diagnosed prior to 1/1/2010: This case demonstrates a relapse of AML. The original classification of Histology as 9863/3 [AML] is correct. There is no second primary based on the information provided for this case. 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. |

20020024 | Reportability--Cervix: The SEER Program Code Manual lists CIN III and carcinoma in situ of the cervix as not being reportable for cases diagnosed in 1996 or later, but does not list "adenocarcinoma in situ" or "squamous cell carcinoma in situ." Are these histologies still reportable? | For primary site cervix uteri, only histologies with behavior codes of 3 [invasive] are reportable to SEER for all registries.
Some SEER registries have opted to continue to collect behavior codes of 2 [in situ] for cervix uteri primaries. |

20021100 | Primary Site: How do we code the primary site for a malignancy that occurs in parenchyma located in an ectopic site? See discussion. | 1. Patient presented with a subcutaneous nodule in right axilla. Pathologic impression by initial and reviewing pathologists is that the lesion represents a breast adenocarcinoma arising in ectopic mammary parenchyma. Subsequent breast biopsies were negative. 2. Patient presented with right branchial cleft cyst. The pathologist states the cyst is a primary thyroid adenocarcinoma arising in an ectopic focus of thyroid tissue. The subsequent total thyroidectomy is negative. |
Code the primary site to the location of the malignancy.
1. Code the Primary Site field to C76.1 [Axilla NOS]. 2. Code the Primary Site field to C10.4 [Branchial cleft]. |

20021154 | Primary Site: What code is used to represent the primary site for a "teratocarcinoma with features of embryonal carcinoma" removed from the thigh muscle in a patient with x-ray negative testicles? See discussion. |
The case was reviewed by AFIP and called "extratesticular." Per our pathology consultant, the site should be coded to unknown because it is very doubtful that the tumor was primary in the soft tissue of the thigh. According to him, such tumors don't originate exclusively in the testes, but tend to occur along the central axis such as the mediastinum or retroperitoneum. If an extratesticular tumor arises in either of these areas, the primary site should be code to the mediastinum or the peritoneum rather than to unknown. Lesions primary in the testicle may also undergo maturation with fibrosis and involution. This process often leaves little evidence of the original tumor in the testis. |
Code the Primary Site field to C809 [unknown] for this case. The thigh tumor is a metastatic site. |

20021099 | Reportability/Histology (Pre-2007)--Pancreas: Are the following pancreatic tumors with mention of "low grade malignant potential/borderline" reportable to SEER? If so, what histology and behavior codes should be used? See discussion. | 1. AFIP diagnosis: Pancreas, tail, resection: Mucinous cystadenocarcinoma (mucinous cystic neoplasm) of low grade malignant potential. Comment: There are no reliable histomorphologic features which can separate these neoplasms into benign and malignant tumors, and so we consider them all to be low grade malignant tumors.
2. Whipple resection: Intraductal papillary mucinous tumor of the pancreas with extensive low grade and multifocal high grade ductal dysplasia (so-called borderline tumor and carcinoma in-situ). |
For tumors diagnosed prior to 2007:
Both tumors are reportable to SEER.
1. Code the Histology and Behavior Code fields to 8470/3 [Mucinous cystadenocarcinoma, NOS].
2. Code the Histology and Behavior Code fields to 8453/2 [Intraductal papillary-mucinous carcinoma, non-invasive].
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules. |

20021079 | Primary Site/Histology (Pre-2007)/EOD Fields/Surgery of Primary Site--Abdomen, NOS: What codes are used to represent these fields for a case with a resection of the rectosigmoid and adjacent tumor mass that demonstrated no tumor in the rectosigmoid but extramural to the colon there was an endometrioid adenocarcinoma arising in association with an area of endometriosis (possibly within the pericolic soft tissue or in an ovarian remnant)? | For cases diagnosed in 2003, code to: Primary Site: C76.2 [abdomen, NOS] Histology: 8380/3 [Endometrioid adenocarcinoma] EOD size, extension, lymph node: 999, 99, 9 [Unknown] Surgery of Primary Site: 98 [All unknown and ill-defined disease sites, WITH or WITHOUT surgical treatment] Scope of Regional LN Surgery: 0 [None] Surgical Procedure of Other Site: 2 [Non-primary surgical procedure to other regional sites]. |

20021172 | EOD-Extension--Head & Neck: How much information is needed for a head and neck primary in order to code extension to localized versus unknown? What code is used to represent this field when the only information for a buccal cavity primary is a positive aspiration of the buccal mass? | For cases diagnosed 1998-2003:
Code the EOD-Extension to 99 [Unknown] for this case until more information is received. The available information does not describe the primary site and there is a complete lack of staging information.
Head and neck cancers spread early and often to nodes. Do not code the EOD-Extension to localized when the information is as limited as it is for this example. |

20021005 | EOD-Extension--Lymphoma: What code is used to represent this field for an extranodal lymphoma that has more than one tumor in the primary site OR has intraluminal extension from the primary site to an adjacent organ? See discussion. | 1. Small lymphocytic lymphoma with 2 tumors in the stomach. 2. Lymphoma involving the cecum and ileum. 3. Lymphoma of the fundus of stomach with extension into the esophagus. |
For cases diagnosed 1998-2003:
Using the EOD scheme for lymphoma, code the Extension field to 11 [Localized involvement of a single extralymphatic organ or site; Stage IE] for all 3 of these cases.
For the stomach lymphoma: There are 2 areas of lymphoma, but it is still confined to one site.
For the other 2 lymphomas: Intraluminal (mucosal) spread of the lymphoma never equals extension. The same phrase that was added to code 21, "Direct extension to adjacent organs or tissues", will be added to code 11 in the Collaborative Stage System. Neither "mucosal spread to a contiguous organ" or "direct extension into a nearby organ" affect staging. Both are still coded to 11 as long as there are no other sites of lymphoma involvement.
EOD code 80 is poorly written. It does not mean diffuse invovement or multiple tumors in a single organ but rather "diffuse disease in two or more organs." |
