20210038 | Update to current manual/First course treatment--Neoadjuvant treatment: How are the 2021 neoadjuvant therapy fields coded when neoadjuvant therapy and surgery were part of first course plans but treatment was never completed. See Discussion. |
Example: Breast case where first course treatment plan is neoadjuvant therapy and surgery after. The patient was hospitalized during neoadjuvant therapy, elected hospice, and later died, so the neoadjuvant therapy was never completed, surgery not done. How are the 2021 neoadjuvant therapy fields coded in this situation as neoadjuvant therapy and surgery were part of first course plans. I coded neoadjuvant therapy to 2 - started but not completed, but there are no codes to properly explain the clinical response and therapy treatment effect as the patient did not complete neoadjuvant therapy. Should I use code 9 for clinical response and treatment effect or should this be left blank for this particular case? |
Assign code 8 for Neoadjuvant Therapy--Clinical Response in this case. We will update the SEER manual to allow code 2, in addition to code 1, in Neoadjuvant therapy when Clinical Response is coded 8. We will also add instructions covering a case such as this one. Assign code 7 for Neoadjuvant Therapy--Treatment Effect and use text fields to record the details. We will add instructions to the manual for this scenario. |

20210045 | Update to Current Manual/Neoadjuvant Treatment: What codes should be used for Neoadjuvant Therapy--Clinical Response and Neoadjuvant Therapy--Treatment Effect when the neoadjuvant therapy is still in progress at the time the case is initially abstracted as with rapid reporting. There is no code for neoadjuvant therapy still in progress and code 9 generates an edit for Neoadjuvant Therapy--Clinical Response. |
Assign code 8 for Neoadjuvant Therapy--Clinical Response and assign a code 9 for Neoadjuvant Therapy--Treatment Effect when the treatment is still in progress. Revise these codes after the treatment has been completed. We will update the manual to include these instructions. |

20081095 | Race, ethnicity/Spanish surname or origin: If birthplace is Brazil or Portugal, patient's last name is on the Spanish Surname list, and there is no text to further clarify ethnicity, what is the correct Spanish Ethnicity code: 0 or 7? See Discussion. | See also SINQ 20081075. | Assign code 7 [Spanish surname only] when the last name is on the Spanish Surname list. This includes cases for which the birthplace is Brazil, Portugal or the Philippines and there is no text to further clarify ethnicity. The instruction to use code 0 [Non-Spanish/Non-Hispanic] in the SEER manual on page 51 (#2) applies when the only information available is the birthplace or a statement of "Portuguese," "Brazilian" or "Filipino." |

20240042 | EOD 2018/EOD Primary Tumor--Cervix: How is Extent of Disease (EOD) Primary Tumor of the cervix coded when it invades into the bladder on surgery and noted as T4. No further information is provided, and it is not possible to contact the physician for clarification. Would you code 550 (Bladder wall; bladder, NOS excluding mucosa), 750 (Bladder mucosa), or 999 Unknown? |
Assign code 550 (Bladder, NOS excluding mucosa) to EOD Primary Site based on invasion into the bladder with no mention of mucosa. EOD Primary Tumor for cervix, Note 1, instructions are to use the extension information to code primary tumor in preference to a statement of FIGO stage when both are available. TNM staging is closely related to FIGO stage, and the surgical findings of bladder invasion NOS in this case should be used in preference to the statement of T4. |

20071120 | Surgery of Primary Site--Breast: Should code 51 (Modified radical mastectomy without removal of uninvolved contralateral breast) be used when a patient has excisional biopsy (22) and axillary dissection followed by a simple mastectomy without removal of uninvolved contralateral breast (41) as part of the first course of treatment? | Assign code 51 or 52 if a patient has an excisional biopsy and axillary dissection followed by a simple mastectomy during the first course of therapy. Code the cumulative result of the surgeries, which is a modified radical mastectomy in this case. SEER collects only one surgery code per case. Code the most invasive, extensive or definitive surgery in Surgery of Primary Site. |

20170079 | Surgery of Primary Site--Corpus Uteri: Is surgery for a uterine corpus primary described as total abdominal hysterectomy-bilateral salpingo-oophorectomy (TAH-BSO) with specimens including uterine corpus, cervix, bilateral ovaries and fallopian tubes, and bilateral parametria coded as a modified radical hysterectomy? It would be very helpful if an explanation of the difference between a total hysterectomy, modified radical hysterectomy, and radical hysterectomy can be included. See Discussion. |
Surgery text indicates TAH-BSO with bilateral pelvic and paraaortic lymph node dissection. The pathology report indicates the specimen includes: Uterine corpus, cervix, bilateral ovaries and fallopian tubes, bilateral parametria. The Gross Description also indicates: Representative sections submitted in 16 cassettes as follows: A1: Anterior cervix A2: Posterior cervix A3: Full thickness anterior lower uterine segment A4: Full thickness posterior lower uterine segment A5: Tumor A6-A7: Full thickness anterior endomyometrium to include tumor A8-A10: Full thickness posterior endomyometrium with tumor A11: Representative sections of right fallopian tube and fimbria A12: Representative sections of right ovary A13: Representative sections of left fallopian tube and fimbria A14: Representative sections of left ovary A15: Right parametrial tissue A16: Left parametrial tissue A17-23: Remainder of cervix. |
Assign code 50: total hysterectomy with removal of tube(s) and/or ovary(ies). Removes both the corpus and cervix uteri. It may also include a portion of the vaginal cuff. Both the radical and modified radical hysterectomy (code 60) include removal of part of the vagina, not mentioned in the pathology or surgery text. The SEER Glossary for Registrars defines the procedures as follows. Total hysterectomy: Surgery to remove the entire uterus, including the cervix Radical hysterectomy: Surgery to remove the uterus, cervix and part of the vagina. The ovaries, fallopian tubes and nearby lymph nodes may also be removed. Modified radical hysterectomy: Surgery to remove the uterus, cervix, upper part of the vagina, and nearby ligaments and tissues. Nearby lymph nodes may also be removed. In this type of surgery, not as many tissues and/or organs are removed as in a radical hysterectomy. |

20210069 | EOD 2018/Summary Stage 2018--Intrahepatic Bile Duct: How should Extent of Disease (EOD) Primary Tumor (PT) be coded for invasion of or into (but not through) the visceral peritoneum for an intrahepatic bile duct primary? See Discussion. |
Invasion of the visceral peritoneum is Regional (code 2) in Summary Stage. EOD PT code 500 is for invasion BEYOND the visceral peritoneum into adjacent connective tissues, and maps to T3 and Regional Summary Stage, but that code seems too extensive. All lower EOD codes map to Localized Summary Stage. |
Assign code 500 for EOD Primary Tumor for now. We have confirmed with AJCC that "invasion of" but not "through" the visceral peritoneum maps to a T2 and not T3. Involvement of the visceral peritoneum for Summary Stage is Regional and does not make a distinction between "invasion of" or "invasion through." Any involvement of the visceral peritoneum is regional. To correct this situation would require a new code, which would derive a T2/RE. That code will be added to the updates for 2023. Code 500 will derive the appropriate Summary Stage of 2 (Regional). We are aware that this will derive the incorrect T; however, there is no work around at this time that will derive the correct T and Summary Stage, so we are defaulting to deriving the correct Summary Stage. |

20230062 | Update to current manual/EOD 2018/EOD Primary Tumor--Appendix: Is it correct to code Extent of Disease (EOD) Primary Tumor as code 500 (Invasion of/through serosa (mesothelium) (visceral peritoneum)) and EOD Mets as code 30 (Intraperitoneal metastasis (peritoneal carcinomatosis) WITH or WITHOUT peritoneal mucinous deposits containing tumor cells), when the resection pathology report for a low-grade appendiceal mucinous neoplasm (LAMN) proves “Tumor Extent: Acellular mucin invades visceral peritoneum (serosa)” as well as metastatic LAMN within the right lower quadrant peritoneum? See Discussion. |
This patient had serosal involvement and the pathologist and managing physician staged this as pT4a disease. This extension seems best captured by EOD Primary Tumor code 500. Additionally, the patient had discontinuous metastatic involvement of the peritoneum, and this was staged by the pathologist and managing physician as pM1b (Intraperitoneal metastasis only, including peritoneal mucinous deposits containing tumor cells). Although this peritoneal involvement was present in the right lower quadrant, it was staged as distant metastatic disease and not as part of the primary tumor category. However, currently EOD Primary Tumor code 600 would seem to apply since the peritoneal tumor was in the right lower quadrant. Code 600 is defined as mucinous tumors with peritoneal involvement confined within right lower quadrant. This EOD Primary Tumor code and the physician’s M category assignment do not align; the physician has staged this as distant metastasis (M category, not the T category). Should the peritoneal metastasis (even limited to the right lower quadrant) be included in the EOD Mets field and not in the EOD Primary Tumor field? In other words, should the peritoneal involvement included in EOD Primary Tumor code 600 be reclassified in EOD Mets code 30 (Intraperitoneal metastasis (peritoneal carcinomatosis) WITH or WITHOUT peritoneal mucinous deposits containing tumor cells)? |
Assign code 500 for EOD Primary Tumor and code 30 for EOD Mets. This will correctly derive the T4aM1b stage based on AJCC 8th edition. Abstraction of peritoneal metastasis changed from the T category in the AJCC 7th edition to the M category in the 8th and 9th AJCC editions. As a result, for cases diagnosed in 2018 and later, peritoneal deposits in the right lower quadrant should be abstracted as EOD Primary Tumor code 500 and EOD Mets code 30. However, the EOD Primary Tumor code of 600 has not yet been updated to align with the 8th and 9th AJCC editions. The 2025 updates will correct for this via a conversion for cases diagnosed in 2018 and forward where EOD Primary Tumor = 600 and EOD Mets = 00 or 10 to EOD Primary Tumor = 500 and EOD Mets = 30. Effective immediately, abstract peritoneal deposits in the right lower quadrant as EOD Primary Tumor code 500 and EOD Mets code 30, even though you will still have the ability to assign EOD Primary Tumor code 600 in your abstraction software until the 2025 updates are deployed. |

20170055 | First Course of Treatment/Surgery of Primary Site--Corpus uteri: Do you code total hysterectomy or radical hysterectomy when a specimen indicates the uterus, cervix, ovaries, fallopian tubes, and right and left parametrium were resected, but shows no portion of the vagina. See Discussion. |
AFS1-AFS2-frozen section control, endomyometrium; AFS3-frozen section control, subserosal intramural mass; A4-anterior cervix; A5-posterior cervix; A6-anterior cervical endometrial junction; A7-posterior cervical endometrial junction; A8-A10-anterior endomyometrium, including tumor; A11-A13-posterior endomyometrium, including tumor and adjacent mass; A14-random section subserosal mass; A15-left parametrium at margin of resection; A16-right parametrium at margin of resection; A17-A18-left ovary and fallopian tube; A19-A20-right ovary and fallopian tube. The final diagnosis includes Endometrial adenocarcinoma, favor serous carcinoma, with papillary and solid areas. Tumor involves: Cervix present, Right ovary, Left ovary, Right fallopian tube, Left fallopian tube, Right parametrium, Left parametrium. |
Assign code 50 for total hysterectomy. According to Appendix C Surgery Codes for Corpus Uteri of the 2016 SEER Coding and Staging Manual, total hysterectomy is surgery to remove the entire uterus, including the cervix; whereas, radical hysterectomy includes the vagina. |

20140025 | Grade--Heme & Lymphoid Neoplasms: Why isn't "T-cell granular lymphocytic leukemia" (9831/3) coded as "5 T-cell" instead of "9" as specified in the Heme database? My path department did not specify any type of grade, but since "T-cell" is part of the name, wouldn't you code it to "5"? |
Assign code 5 when the diagnosis on the pathology report specifies "T-cell granular lymphocytic leukemia." The Heme DB grade instruction states "Code grade specified by pathologist. If no grade specified, code 9." In this case, T-cell was specified - code it. The code for T-cell (5) was not automatically assigned in the Heme DB because of the alternate names for this neoplasm. Some of these include NK-cell. Assign code 8 for alternate names with NK.
The alternate names are: Chronic lymphoproliferative disorder of NK cells, Chronic NK-cell lymphocytosis, Chronic NK-large granular lymphocyte (LGL) lymphoproliferative disorder, CLPD-NK, Indolent large granular NK-cell lymphoproliferative disorder, NK-cell lineage granular lymphocyte proliferative disorder, NK-cell LGL lymphocytosis |
