20031051 | Histology (Pre-2007)/Sarcoma: What code is used to represent the histology "Ewing's Sarcoma/Primitive Neuroectodermal Tumor (PNET)"? See Description. | A comment on one path report states "some authors consider both Ewing's & PNET to be the same biologic entity given that they share the same translocation between chromosomes 11 & 22." The pathologists at our children's hospital agree with this statement and contend that the two should have the same histologic code. | For tumors diagnosed prior to 2007:
Code histology as 9260/3, Ewing sarcoma. Ewing sarcoma is a specific histology on the continuum of primitive neuroectodermal tumors. Code Ewing sarcoma as it is more specific than PNET, NOS.
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. |

20031034 | Histology (Pre-2007)--Kidney, renal pelvis: What codes are used to represent the histologies of 1) "renal papillary (chromophil) carcinoma" and 2) "chromophil renal cell carcinoma?" |
For tumors diagnosed prior to 2007: Code "chromophil" to 8260 [papillary renal cell]. According to our pathologist consultant, in the case of chromophil, most authors regard this as more or less synonymous with papillary renal cell [8260]. "More or less" because papillary is an old term descriptive of the microscopic structure, while chromophil is newer and based on the cytology; because most of the latter are papillary the current usage assumes them to be equivalent. 1) The diagnosis "renal papillary (chromophil) carcinoma" tells us that the pathologist who wrote it was seeing both pattern and cytologic features, and is regarding papillary equivalent to chromophil; thus, code to 8260. 2) Code "chromophil renal cell carcinoma" to 8260. 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. |

20031143 | Ambiguous terminology/EOD-Extension: Is the term "within" a term of involvement in coding extent of disease? See Description. |
For example: a kidney tumor is described as "completely encased within the renal capsule with no extension into perirenal fat." Does this mean the renal capsule has been invaded (extension code 20) or that the tumor is totally contained within an area surrounded by the renal capsule (extension code 10)? |
For cases diagnosed 1998-2003: The term "within" is not one of the listed ambiguous terms for EOD. Determine extent of involvement from the context in which "within" appears. In the example, "Encased" is an ambiguous term meaning not involved. Code extension for the example to 10 [Invasive cancer confined to kidney cortex and/or medulla]. |

20031055 | Histology (Pre-2007)/Primary Site/Diagnostic Confirmation: How would these fields be coded for a diagnosis of cholangiocarcinoma based on clinical findings only? See Discussion. |
We have a case of reported "cholangiocarcinoma" of the liver diagnosed only by a CT of the abdomen. There is no pathologic confirmation. CT ABD: Heterogeneous liver mass suspicious for cholangiocarcinoma; mass causes right portal & right hepatic vein occlusion & right and left biliary duct dilatation.... Should this be coded to cholangiocarcinoma by radiology alone and should it be liver as primary site? |
For tumors diagnosed prior to 2007: Code according to the prevailing medical opinion in this case. If no further information can be obtained, code as cholangiocarcinoma of the intrahepatic bile duct. 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. |

20031193 | Surgery of Primary Site--Lung: Is a core-out of the main bronchus coded in this field? See Description. | Patient with right lung cancer was not a surgical candidate because of extent of disease. Prior to receiving radiation, patient underwent bronchoscopy, which revealed obstruction from right main bronchial tumor. Core-out of the tumor was undertaken, and a specimen was sent for path evaluation. The physician stated that this was a palliative procedure to relieve obstruction. | Do not code bronchoscopy to clear the airway as surgery of primary site. When combined with laser therapy, cryosurgery, or other tumor destruction, or when combined with excision of tumor, code as surgery of primary site.
For cases diagnosed 1998-2003: Code surgery of primary site for the case described above to 23 [Excision, NOS]. Tissue was excised and sent to pathology. |

20041064 | CS Tumor Size/CS Extension/CS TS/Ext-Eval--Breast: How do you code these fields when the tumor size and extension differ pre and post treatment with neoadjuvant Arimidex? See Discussion. | Clinically on PE 3 cm mass attached to skin with dimpling and erythema overlying the mass. Ultrasound: 2-3 cm breast mass with overlying skin thickened by US evaluation, suggesting dermal invasion. Neoadjuvant Arimidex followed by MRM. Path: 4.5 cm ductal carcinoma (no DCIS), no invasion of skin. | This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Record the larger tumor size and the farthest extension documented.
Code CS Tumor Size/Extension Evaluation to 6 [Surgical resection performed, WITH pre-surgical systemic treatment...; tumor size/extension based on pathologic evidence].
Code CS Tumor Size for the example to 045 [4.5 cm].
Code CS Extension to 20 [Local skin involvement ...] based on clinical description provided. |

|
20041002 | CS Size of Tumor/CS Extension--Brain and CNS: How should these fields be coded for benign CNS tumors? | This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Code CS Extension as 05 [Benign or borderline brain tumors]. Code the size of the tumor if specified. Otherwise code CS Tumor Size as 999 for benign CNS tumors. |

|
20041091 | Primary Site/Summary Stage 2000/EOD-Extension--Lymphoma: How are these fields coded when a CT Impression states: Large retroperitoneal/abdominal mass resulting in extra-hepatic biliary obstruction & bilateral urinary tract obstruction & encasement of major vessels most c/w lymphoma? See Discussion. | CT findings state: Very lg sft tiss mass encasing pancreatic head & portion of body, splenic & portal veins, celiac axis, sup mesenteric artery & bilateral renal veins. Two components to this mass: 1) retroperitoneal mass encasing great vessels and 2) peritoneal component 10.8cm size, displaces bowel & other structures & encases vessels.
If the physician stated "this is bulky disease" would that change the EOD? |
For tumors diagnosed 1998-2003:
Based on the information provided: The topography code for this lymphoma is C772 [Intra-abdominal lymph nodes]. Code SEER Summary Stage 2000 to 5 [Regional NOS]. Code EOD Extension to 20. More than one lymph node region below the diaphragm is involved (retroperitoneal and peritoneal). The organs mentioned are not involved by the lymphoma. The bulk of the masses is causing obstruction by displacing and/or encasing organs. A physician description of "bulky disease" would not change the EOD for this case. |

20041073 | Primary Site/Histology--Lymphoma: How are these fields coded when the final diagnosis per the pathology report is, "Soft tissue and skeletal muscle, left thigh--Large B cell lymphoma with polyclonal and mature t-cells, involving the soft tissue"? | For cases diagnosed prior to 1/1/2010:Site: C492 [Soft tissue thigh] Histology: 9680/36 [T-cell rich large B-cell lymphoma] 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. |

20041066 | Reportability/Date of Diagnosis--Ovary: Is a patient SEER reportable in 2001 or 2003 if she presented with a diagnosis of papillary serous tumor of low malignant potential [borderline tumor] per the 5/2001 surgery but at the time of the planned second look laparoscopic surgery is stated to have Stage 3A ovarian cancer? See Discussion. |
A patient was seen in 5/2001 for large pelvic mass growing from right ovary. After TAH and USO and partial omemtectomy, path diagnosis was papillary serous tumor of low malignant potential (borderline tumor), unruptured. Right ovary and omental implant have identical histologic appearance, except the psammoma body formation and the ovary does not. Patient does not return for lap as planned in 6-12 months. In 1/03 she returns to hospital with abdominal pain and has debulking, hemicolectomy and Hartmann's procedure. 1/03 Path report "metastatic papillary serous adenoca." Chart now says "History of stage 3A ovarian cancer." |
Yes, this case is reportable in 2003. Malignancy was confirmed in 2003. The diagnosis made in 2001 is not reportable for that year, and was not reviewed or revised according to the information provided. |
