20230067 | First Course Treatment/Scope of Regional Lymph Node Surgery--Breast: How is Scope of Regional Lymph Node Surgery coded when initially there is a sentinel lymph node biopsy (SLNBx) and an intramammary node removed followed a month later by an axillary dissection for a right breast primary? See Discussion. |
Patient has a diagnosis of invasive carcinoma of the right breast from a core biopsy on 04/2023. Subsequent bilateral mastectomy and sentinel node biopsy proves one positive sentinel node and one negative intramammary node. One month later there is a completion axillary node dissection with 15 nodes negative for malignancy. Per previous SINQ 20190074, the initial mastectomy and sentinel node excision with intramammary node removal should be coded as Scope of Regional Lymph Node Surgery 6. It is unclear how the resulting axillary dissection should be recorded in Scope of Regional Lymph Node Surgery. There is no code for sentinel node biopsy and 3, 4, or 5 at same time (code 6) PLUS an additional subsequent axillary dissection. Please provide coding instructions for Sentinel Lymph Nodes Positive, Sentinel Lymph Nodes Examined, and Scope of Regional Lymph Node Surgery in this scenario. |
Scope of Regional Lymph Node Surgery: Assign code 7, Sentinel node biopsy and code 3, 4, or 5 at different times. In this case, the SLNBx (code 2) preceded the regional node dissection (code 5: 4 or more regional lymph nodes removed), i.e., procedures performed in separate surgical events. Sentinel Lymph Nodes Examined: Assign code 98, Sentinel lymph nodes were biopsied, but the number is unknown. In this case, only the results were provided. Sentinel Lymph Nodes Positive: Assign code 01, Sentinel nodes are positive (code exact number of nodes positive). In this case, there was one positive sentinel node. |

20230023 | Solid Tumor Rules/Multiple Primaries—Brain and CNS: How many primaries are accessioned, and which M Rule applies, to a 2018 of pituitary adenoma (8272/0) that was partially resected followed by a 2023 resection of residual disease proving pituitary adenoma/pituitary neuroendocrine tumor (8727/3)? See Discussion. |
The patient had residual tumor following the 2018 transsphenoidal resection and underwent an additional surgery after the residual tumor increased in size. Since pituitary adenoma/pituitary neuroendocrine tumor (PitNET) is a new malignant neoplasm for cases diagnosed 2023 and later, should this be a new primary per M5? Or do we disregard the change in behavior and apply rule M2 (single tumor is a single primary) for this scenario? |
This case does not fall into the standard rules. WHO criteria for diagnosing pituitary adenoma have recently changed (per 5th Ed WHO CNS book) and we will likely see more PitNET’ s than pituitary adenomas in the future. PitNET may be invasive or non-invasive but the likelihood of the pathologists providing this information is low. Since we don’t know if the 2018 adenoma was a PitNET based on current criteria or if it transformed to the malignant neoplasm, err on the side of caution and abstract a second primary per M5. This issue is new, and we’ve received numerous questions concerning pathologist reviewing older cases of pituitary adenoma and reclassifying them as PitNET using the new criteria. |

20230034 | Update to Current Manual/Surgery of Primary Site 2023--Melanoma: Considering the 2023 melanoma surgery codes for punch biopsy NOS (B220) and shave biopsy NOS (B230), how is Date of First Surgical Procedure coded when the punch or shave biopsy is not excisional? See Discussion. |
Now that there are specific surgery codes for shave and punch biopsies, are these biopsies always the Date of First Surgical Procedure (NAACCR Item #1200)? Or should we still be applying the Surgery of Primary Site 2023 instruction in the SEER Manual that states shave or punch biopsies are most often diagnostic; code as a surgical procedure only when the entire tumor is removed and margins are free/gross disease is removed? Example: On 01/01/2023, patient has a frontal scalp shave biopsy showing melanoma, margins involved. On 02/01/2023, frontal scalp excision shows residual melanoma. Surgery code is assigned B520 (shave followed by wide excision). How is Date of First Surgical Procedure coded now that there is an additional surgery code for the shave biopsy? |
Code the Date of First Surgical Procedure as 01/01/2023 in the example provided where the shave biopsy is followed by wide excision. Beginning in 2023, significant changes were made in that shave, punch, and elliptical biopsies are coded as surgical procedure regardless of margin status. Appendix C Skin Surgery Codes state that an incisional biopsy would be a needle or core biopsy of the primary tumor. Please see Appendix M: Case Studies for Coding Melanoma in STORE v23, Case study 2: Shave Biopsy followed by WLE (page 412), for an explicit example of how to code your example case. We will clarify this in the upcoming release of the SEER manual, |

20230029 | Primary Site--Skin: Are perianal skin primaries within 5 cm of the anus coded as perianal skin (C44.5) or anus (C21.0). See Discussion. |
ICD-O-3 tells us that perianal skin is C445 and we do not capture basal or squamous cell skin cancers in our registry. The AJCC manual stages perianal skin cancers within 5 cm of the anus with the anus chapter. We cannot AJCC stage them as an anus if we are not capturing them as C445. I realize we do not code a site in order to stage. We have been following the reportability rules and not capturing. Is this correct? I do not see this addressed in the new Other Sites Solid Tumor Rules. |
Code primary site based on the site of origin as determined by the physicians. If the physicians state the site of origin is anus, code anus; the same as with skin. As you state, squamous cell cancer of sites coded to C44 is not reportable. The AJCC instruction for physicians to stage perianal neoplasms within 5 cm of the anus using the Anus chapter does not change cancer registry instructions for coding primary site, nor does it affect cancer registry reportability instructions. |

20230049 | Update to Current Manual/Surgery of Primary Site 2023--Skin: Regarding the 2023 skin surgery codes for punch biopsy NOS (B220) and shave biopsy NOS (B230), how is Date of First Surgical Procedure coded for cutaneous lymphoma and Kaposi sarcoma when the punch or shave biopsy is not excisional? See Discussion. |
Now that there are specific surgery codes for shave and punch biopsies, are these biopsies always the Date of First Surgical Procedure (NAACCR Item #1200)? Or should we still be applying the Surgery of Primary Site 2023 instruction in the SEER Manual that states shave or punch biopsies are most often diagnostic; code as a surgical procedure only when the entire tumor is removed and margins are free/gross disease is removed? We are aware of the instruction for melanoma cases outlined in SINQ 20230034; however, it is unclear if this should also apply to cutaneous lymphomas and Kaposi sarcomas, or if the intent of the procedure is used for these specific types of skin cases that typically present with multifocal involvement. Example 1: Patient is diagnosed March 2023 with primary cutaneous T-cell lymphoma presenting as pink, tan patches on the trunk. Punch biopsy diagnosed CTCL and treatment was given via narrow band UVB phototherapy. Example 2: Patient is diagnosed February 2023 with Kaposi sarcoma presenting as widespread violaceous macules, papules, plaques on the torso, bilateral extremities, and abdomen. Punch biopsy diagnosed Kaposi sarcoma. |
Code the Date of First Surgical Procedure (NAACCR Item #1200) as the date the shave, punch, or elliptical biopsy was performed. This instruction applies to cutaneous lymphoma and Kaposi sarcoma as well. Beginning with cases diagnosed 2023 and after, shave, punch, or elliptical biopsies are coded as a surgical procedure regardless of margin status. The instruction in the 2023 SEER Manual that states "shave or punch biopsies are most often diagnostic; code as a surgical procedure only when the entire tumor is removed and margins are free/gross disease is removed" has been deleted from the 2024 SEER Manual. Refer also to the Appendix C Coding Guidelines for Kaposi Sarcoma of All Sites and Lymphoma for coding primary site. |

20230069 | First Course Treatment/Immunotherapy--Colon: Is infliximab cancer directed treatment? See Discussion. |
While SEER*Rx does indicate infliximab should be coded as biological response modifier (BRM)/Immunotherapy, the manufacturer website for this medication indicates it is given for: Crohn’s disease, ulcerative colitis, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and plaque psoriasis. In addition, SEER*Rx does not indicate which primary sites this treatment may be given for. If it is indeed cancer directed treatment, can the typical primary sites be added for clarity? Case example: Patient is diagnosed with colorectal cancer and also has an existing diagnosis of Crohn’s disease; received surgery and FOLFOX6, as well as infliximab. There was no statement of what disease the infliximab was given to treat. |
infliximab is not cancer-directed treatment. This drug was last updated by the FDA 2/22/2023 with additional information on its approval to treat non-malignant neoplasms. To date, the FDA has not approved it for use in colon cancer. This drug was intially developed to treat colon cancer; however, found to be ineffective treating cancer. |

20230036 | Reportability/Histology--Vulva: Is angiomyxoma (8841/1), such as aggressive angiomyxoma of vulva diagnosed in 2022, reportable? |
Do not report superficial angiomyxoma (8841/0) or aggressive angiomyxoma (8841/0). WHO Classification of Female Genital Tumors, 5th edition, defines deep (aggressive) angiomyoma as a benign, infiltrative, myxoid spindle cell neoplasm that occurs in deep soft tissue of the pelviperineal region. |

20230080 | Solid Tumor Rules/Histology--Brain and CNS: What is the histology code for low grade glioma? See Discussion. |
Patient has a 3 cm tumor in the temporal lobe of the brain. This was noted on MRI 12/2022. The radiologist states this is a low-grade glioma and recommends following with routine scans. No pathology or resection performed or planned. Patient has been followed with imaging every six months with stable disease. Low grade glioma is not currently listed in ICD-O-3.2 or the current Solid Tumor Rules. What histology should be assigned to the case? |
Assign 9380/1 for low grade glioma diagnosed 1/1/2018 forward and for low grade glioma diagnosed prior to 1/1/2018 assign code 8000/1 on the advice of our expert neuropathologists. The site/type combination of C71 _ and 9380/1 will flag histology/site/behavior edits which should be overridden. Low grade glioma is an umbrella term or non-specific diagnosis, primarily seen on radiologic reports such as CT scans and MRIs. Often, the patient is actively followed with scans and surgical intervention delayed or not recommended. WHO Classification of Central Nervous System Tumors, 5th edition, does not recognize this term and indicates that tissue diagnosis (including genetic testing) is needed to provide a specific diagnosis. Since biopsy of these “neoplasms” is not routinely done, a definitive diagnosis is not available. Literature searches yielded conflicting information with some stating low grade gliomas are malignant with an indolent clinical course while others felt they were benign. Until such time as WHO proposes a code for this neoplasm, our expert neuropathologists recommend coding glioma, NOS with borderline behavior 9380/1. |

20230044 | First Course Treatment/Neoadjuvant Therapy--Breast: What pathology report descriptions are permissible to use in coding the Neoadjuvant Therapy Treatment Effect data item? See Discussion. |
1) In the SEER Manual's code definitions for Neoadjuvant Therapy - Treatment Effect, some sites specify the percentage of viable tumor. Pathology reports often list this along with the percentage of necrosis (e.g., 10% necrosis and 90% viable tumor). If only the percent necrosis is stated, is it acceptable to infer the percent viable tumor? For example, pathology report states only "treatment effect: present, necrosis extent: 30%" - could we then deduce that the percent viable tumor in this case would be 70%? 2) Can statements of Residual Cancer Burden (RCB) Class be used? For example, pathology report states Treatment Effect: Residual Cancer Burden Class II, with no further description of partial vs. complete response. It appears that RCB Class II is a "moderate burden" of residual tumor after neoadjuvant therapy; could this be interpreted as a partial response in the Neoadjuvant Therapy--Treatment Effect code definitions? |
1) Do not infer the percent of viable tumor if only percent of necrosis is provided. For the example, assign code 6 when Neoadjuvant therapy was completed and the treatment effect in the breast is stated only as “Present". 2) Do not use the residual cancer burden (RCB) score from the pathology report to code the Neoadjuvant Therapy--Treatment Effect field for breast cancer. We do not have a crosswalk from RCB to neoadjuvant Therapy--Treatment Effect. RCB index is an accurate and reliable tool to assess patient prognosis. RCB is estimated from routine pathologic sections of the primary breast tumor site and the regional lymph nodes after the completion of neoadjuvant therapy. The data item Neoadjuvant Therapy--Treatment Effect records information on the primary tumor only. Document information in a text field in both examples. |

20230068 | Solid Tumor Rules/Histology--Thyroid: What is the histology code for a diagnosis of poorly differentiated thyroid carcinoma arising in a background of solid papillary thyroid carcinoma? See Discussion. |
Patient had a hemithyroidectomy with the final diagnosis above. There does not appear to be an Other Sites H rule or table that addresses this combination of histologies for thyroid primaries. |
Code to poorly differentiated thyroid carcinoma, 8337/3. In this case the tumor is comrpised of two difffernat thyroid histologies: poorly differentiated carcinoma 8337/3 and papillary thyroid carcinoma 8260/3. WHO does not have a code for this combination. Per our endocrine pathology expert, the poorly differentiated carcinoma is the more agressive histology and will determine treatment and progrnosis. |
