20091112 | Grade-Breast: How is this field coded for a breast tumor described as "intermediate nuclear grade"? See Discussion. | Guidelines for selecting grade for breast primaries prioritize nuclear grade right after B&R grade. The conversion table displays only numeric values for nuclear grade. How is grade coded for tumors in which nuclear grade is described by terminology? Does it make a difference if the tumor is invasive or in situ?
Example 1: Ductal carcinoma, intermediate nuclear grade. Example 2: Ductal carcinoma, high nuclear grade. Example 3: Ductal carcinoma, moderate nuclear grade. Example 4: DCIS, intermediate nuclear grade. |
Use the table on page C-607 of the 2007 SEER manual. The terms "low," "intermediate," and "high" appear in the column labeled "BR Grade." Use this column to determine the appropriate grade code when grade is described using these terms. If the grade of an in situ tumor is described using these terms, use the table to determine the appropriate code for the grade field. | 2009 |

20091021 | Behavior/Reportability--All sites: Would a GIST tumor stated to be "high risk for malignant behavior" be a reportable GIST? See Discussion. |
According to our pathologist and oncologist, the terms "malignant" and "benign" do not apply to GIST. Rather, the term "high risk for malignant behavior" is used. This is based on tumor size: greater than 5 cm and mitotic activity: greater than 5 mitoses/50 hpf. |
Do not report the case to SEER if it does not satisfy the criteria for reportability. According to the current reportability criteria, malignant GIST (8936/3) is reportable to SEER. GIST coded to 8936/0 or 8936/1 is not reportable. If your pathologist will not indicate "malignant" or "benign," code 8936/1 applies according to ICD-O-3 and, therefore, these are not reportable to SEER. |

20091114 | MP/H Rules/Multiple primaries--Breast: Would a left chest wall mass excision stated to be ductal carcinoma consistent with a breast primary and, "compatible with either local recurrence or potentially a metastasis" be a new primary per the MP/H rules? See Discussion. | Patient underwent mastectomy in 1986 for infiltrating ductal carcinoma of left breast. Excision of left chest wall mass in March 2009 showed ductal carcinoma consistent with breast primary. The pathology report COMMENT stated it would be compatible with either local recurrence or a metastasis. The patient's primary breast carcinoma material is not available for direct comparison and the MP/H rules instruct us to ignore metastasis. | For cases diagnosed 2007 or later, the MP/H rules do not apply to metastasis. If there is no further information available for this case, the MP/H rules do not apply to the 2009 diagnosis. | 2009 |

20091131 | Multiplicity Counter/Type of Multiple Tumors--Breast: How are these fields coded when a patient underwent a lumpectomy demonstrating two measured foci of invasive ductal carcinoma (1.5 cm and 3 mm) and "focally seen" in situ ductal carcinoma (DCIS) followed by a re-excision that is positive for 1.5 mm focus of residual invasive carcinoma? See Discussion. | Lumpectomy path shows two foci of invasive ductal carcinoma, 1.5 cm & 3 mm sizes, and CAP summary lists "DCIS: focally seen", no further description. The re-excision pathology specimen finds a 1.5 mm focus of residual invasive carcinoma, very close to the new inferior margin (so registrar assumed this was probably not part of the previously excised mass), and no mention of any more in situ.
Can we assume the DCIS was associated with/part of the invasive tumors because it was not measured or described separately? If we say there are 3 tumors (for the measured invasive foci), should Type of Multiple Tumors be coded 30 [In situ and invasive] or 40 [Multiple invasive]?
|
Code 03 [3 tumors] in the multiplicity counter. Do not count the "focally seen" DCIS because it was not measured. Code 30 [In situ and invasive] in Type of Multiple Tumors Reported as One Primary. The single primary reported for this case is a combination of in situ and invasive tumors. |

20091036 | CS Mets at DX/CS Extension--Ovary: Is carcinomatosis always captured in the CS Mets field? Can the term carcinomatosis be used to describe peritoneal implants as well? See Discussion. | 1/18/06 CT guided biopsy of abdominal mass & ant peritoneum nodule: Extensive carcinomatosis affecting the paracolic gutters, liver surface & pelvis. 6 cm tumor mass was visibly engulfing the small bowel & tube; poorly differentiated adenoca, mullerian derived, shows attributes of clear cell carcinoma, high grade (FIGO III), 2.5 cm size, does not involve fallopian tube. R&L abdominal wall & mesentery, mets adenoca. 5/31/06: tumor debulking with right salpingo-oophorectomy. Final DX: Poorly differentiated adenocarcinoma, clear cell type, right ovary (FIGO III), stage IV per MD. |
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.In the case of ovarian cancer, the term carcinomatosis may refer to peritoneal implants, especially when the implants are numerous. It does not refer to distant metastases in this context. This issue has been forwarded to the CS version 2 committee. |

20091100 | MP/H Rules/Histology--Melanoma: How is histology coded for a "melanoma in situ, lentiginous type," arising in the skin of the lower leg? See Discussion. |
In researching this, acral lentiginous melanoma is observed on the palms, soles and under the nails. To code to 8744, do we specifically have to see the word "acral" lentiginous melanoma? |
For cases diagnosed 2007 to 2020 Assign 8742/2 [lentigo maligna] to "melanoma in situ, lentiginous type." Acral lentiginous melanoma is not the same as melanoma, lentiginous type. "Acral lentiginous melanoma," 8744, should be used only if the report states acral lentiginous melanoma or malignant melanoma, acral lentiginous type. Acral lentiginous melanoma most often occurs on the soles of the feet or the palms of the hands. |

20091035 | CS Extension--Ovary: What code is used to capture omental caking? | 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.The term "omental caking" refers to a thickened omentum. In the case of ovarian cancer, omental caking is always indicative of involvement of the omentum. The omentum is an abdominal structure for the purposes of CS extension. Assign the appropriate code between 70-73.
When the size of implants is not stated, but operative report and scans state omental caking, code 71 would be best. When there are no size measurements on the operative report or scan or elsewhere, there is not enough information to assign 72. The choice of code between 70 and 73 will depend on the details of the specific case. |

20091017 | Primary site--Esophagus: How is primary site coded for a tumor arising in a segment of the esophagus that was reconstructed using a segment of the colon? See Discussion. |
A patient had a ruptured esophagus 25 years ago and had a segment of colon removed and transplanted to serve as esophagus. In 2007, the patient was diagnosed with carcinoma in a polyp by endoscopic biopsy of the transplanted 'esophagus'. What is the primary site code? Is this the same site schema to be used for Collaborative staging and surgery coding? |
Code the primary site esophagus, NOS [C159]. Use the surgery codes and collaborative staging schema for esophagus. Document the unusual nature of this case in text fields. |

20091001 | CS Lymph Nodes/CS Mets at DX--Ovary: Are lymph nodes in the pericolic mesentery of the sigmoid that are removed during ovarian cancer debulking surgery, coded as regional or distant? See Discussion. | Debulking surgery found tumor in both ovaries and in lymph nodes of pericolic mesentery, which was removed en bloc with a segment of sigmoid colon (colon had tumor implants involving serosa). Pericolic nodes are not listed as regional for ovary. However Note 2 in the CS manual for Extension states "sigmoid mesentery" is a regional pelvic organ, and that metastatic deposits here should be coded in the extension field, not as distant mets. Should lymph nodes from this same area be coded as regional or distant? | 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. Lymph nodes in the mesentery of the sigmoid colon are regional for an ovarian primary. Code involved sigmoid mesenteric nodes under CS Lymph Nodes. |

20091104 | MP/H Rules/Histology--Esophagus: How is histology coded for a biopsy of the esophagus with a pathologic diagnosis of "adenocarcinoma, intestinal type" when there is no evidence of a gastric tumor in scans or EDG? See Discussion. | There is a rule for colon to disregard "intestinal type" and code to adenocarcinoma (8140) but no rule for esophagus. How should histology for this esophageal case be coded? | For cases diagnosed 2007 or later: Follow MP/H Other Sites Rule H11 and code 8144/3 [Adenocarcinoma, intestinal type]. Adenocarcinoma, intestinal type, is called that because it resembles the normal pattern of adenocarcinoma seen in the large intestines. It is not an indication of the location of the adenocarcinoma. We find that it is not uncommon in the sinuses, stomach, lungs, cervix, and many other organs. |
