20041050 | Surgery of Primary Site--Rectum: How do you code a procedure described as a "transanal resection, debulking of a large rectal mass"? See Discussion. | Patient is not a surgical candidate due to "other medical conditions". Colonoscopy done for anemia and rectal bleeding. At the colonoscopy a "Transanal Resection Debulking of large rectal mass" is performed. Two specimens are sent to the lab. The first is labeled "rectal mass" and is a 2.0 cm diameter spherical fragment of tissue. The second is labeled "transanal debulking rectal mass" and is described as multiple, irregular shaped fragments of tan, rubbery tissue measuring 5.0 x 5.0 x 3.0 cm. Final path diagnosis: Debulking of rectal mass: Adenocarcinoma greater than 2 cm in size, resection margins positive for tumor. | For cases diagnosed 1998-2002, code Surgery of Primary Site to 20 [Local tumor excision, NOS]. Because the procedure was performed via colonoscopy and apparently did not involve proctectomy, the best choice is a local excision. | 2004 |
|
20041031 | CS Extension--Bladder: How should this field be coded when the pathology states "papillary transitional cell carcinoma with no invasion into the submucosa or deep muscularis" but there is "focal extension of tumor into bladder diverticula"? | 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 the CS Extension field to 01 [Papillary transitional cell carcinoma stated to be noninvasive]. Extension into bladder diverticula does not change the code. Diverticula are pouches in the mucosa (mucous membrane). |

20041013 | Primary Site--Ovary/Peritoneum: Should this field be coded to ovary or peritoneum when the bulk of the tumor is in the peritoneum and there is only surface involvement of the ovary? | If it is not clear where the tumor originated, use the following criteria to distinguish ovarian primaries from peritoneal primaries. The primary site is probably ovarian, unless: --Ovaries have been previously removed --Ovaries are not involved (negative) --Ovaries have no area of involvement greater than 5mm. Descriptions such as "bulky mass," "omental caking" probably indicate an ovarian primary. Descriptions such as "seeding," "studding," "salting" probably indicate a peritoneal primary. |

20041103 | Histology (Pre-2007)/Behavior Code/Sequence Number-Central -- Ovary: How are these fields coded for a "serous tumor of low malignant potential" when lymph nodes are discovered to be involved? | For tumors diagnosed 2001-2006:
This ovarian tumor is not SEER reportable if diagnosed between 2001-2006. The histology and behavior codes are 8442/1 [serous cystadenoma, borderline malignancy]. Sequence is coded appropriately from 60-88 [non-malignant tumor or central registry-defined neoplasm].
The behavior code could be changed to /3 only when the pathologist states that the disease is malignant. Approximately 20% of serous tumors of low malignant potential have lymph node involvement, according to the WHO Classification of Ovarian Tumours. In ovarian serous tumors of low malignant potential, lymph node involvement is not always equivalent to metastasis and does not signify malignancy in these tumors unless definitely stated as such by the pathologist.
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. |

20041080 | Behavior Code/CS Extension--Brain and CNS: How are these fields coded when the final diagnosis on pathology indicates that an atypical meningioma invades the brain and the bone flap specimen indicates extensive invasion through the full thickness of the calvarium? See Discussion. |
FDx on the path is: A. Rt frontotemporal brain tumor: Atypical meningioma, WHO grade II (out of III). B. Arachnoid tissue: Atypical meningioma with small focus of invasion into superficial brain and focal perivascular spread. C. Bone flap: Atypical meningioma with extensive invasion through full thickness of the calvarium. Comment: Although this tumor shows a small focus of brain invasion, it should be considered a grade II (out of III) meningioma based on its histologic atypia (cellularity, sheeting of tumor cells and prominent nucleoli), elevated Ki-67 index and low mitotic rate. |
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.For tumors diagnosed prior to 2004, the example above is a benign meningioma and not reportable to SEER. For tumors diagnosed 2004 or later, code the behavior as 1 [Borderline malignancy]. Code CS Extension as 05 [Benign or borderline brain tumors]. According to expert consultant, meningiomas are in the lining cells for the inner table of the skull and as such have an affinity for bone that allows them to penetrate adjacent bone without being "malignant. |

20041088 | CS Extension/EOD Extension--Renal Pelvis: Primary site is renal pelvis with direct extension to the rt adrenal gland. What is the correct extension code? | 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. Assign CS Extension code 67 [Adrenal gland from renal pelvis] for adrenal extension from renal pelvis -- T4 and regional direct extension. |

20041006 | Multiple Primaries (Pre-2007)/Date of Diagnosis--Bladder: How is date of diagnosis coded when metastases consistent with a bladder primary are found more than a year after a diagnosis of non-invasive bladder cancer? See Description. | A non-invasive papillary transitional cell carcinoma is removed by TURB in May 2002. In January 2003, a bone biopsy reveals metastatic transitional cell carcinoma consistent with bladder primary. | For tumors diagnosed prior to 2007:
Code a second bladder primary diagnosed in January 2003.
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. |

20041009 | Diagnostic Confirmation--Lymphoma: Can lymphoma be diagnosed clinically? See Description. | Example 1: Patient with B symptoms. Physical exam reveals large neck mass. Physician impression is lymphoma. Example 2: CT scans show lymphadenopathy consistent with lymphoma. In both cases, patient does not return for biopsies. |
Yes, lymphoma can be accessioned based on a clinical diagnosis. Code Diagnostic Confirmation in Example 1 as 8 [Clinical diagnosis only]. Code Diagnostic Confirmation in Example 2 as 7 [Radiography and other imaging techniques without microscopic confirmation]. |

20041086 | Histology (Pre-2007)/CS Tumor Size/CS Extension--Colon: How are these fields coded if a 3 cm sessile polyp is snared and removed piecemeal during a colonoscopy and the path microscopic description indicates a polypoid lesion with foci of malignant transformation found associated with bundles of smooth muscles followed by a LAR with no residual invasive tumor but the final path diagnosis is stated to be a M.D. adenocarcinoma? See Discussion. | 3/04 colonoscopy 3cm sessile polyp snared & removed piecemeal. Path Micro: Polypoid lesion consists of branching & complex neoplastic glands lined by tall columnar epithelial...These foci of malignant transformation are assoicated with large polygonal epithelial...associated with desmoplastic stromal reaction & neoplastic glands can be found associated with bundles of smooth muscle. 4/04 LAR: focus of residual HG dysplasia: no residual invasive tumor. Final path dx: MD adenocarcinoma. Physician staged: T2 N0 M0. Histology: 8140 vs 8210 Tumor Size: 030 vs 999 vs 990 Extension: 12 vs 20 |
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. For tumors diagnosed prior to 2007:
Based only on information provided: Histology: 8210 [Adenocarcinoma in a polyp] Tumor Size: 999 [Unknown] CS Extension: 20 [Muscularis propria invaded]
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. |

20041049 | Histology (Pre-2007): What code is best used to represent a diagnosis of "metaplastic carcinoma, matrix producing type." The tumor shows poorly differentiated infiltrating duct carcinoma and myxoid, cartilaginous stroma. | For tumors diagnosed prior to 2007:
Code the histology to 8575 [metaplastic carcinoma, NOS]. According to the WHO Classification of Tumors of the Breast and Female Genital Organs, metaplastic carcinoma is a type of epithelial breast tumor. Matrix producing carcinoma is a synonym of metaplastic carcinoma. ICD-O-3 does not have a code for matrix producing carcinoma.
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. |
