20230054 | Reportability/Histology--Pancreas: According to SINQ 20140058, solid pseudopapillary neoplasm of the pancreas is reportable (as of 2014). However, per ICD-O-3.2, this histology is not reportable until 2021+. Please clarify which is correct and clearly state the timeframe that it was reportable or not reportable. |
Solid pseudopapillary neoplasm of the pancreas is reportable for cases diagnosed in 2014 and later. Report solid pseudopapillary neoplasm of the pancreas (8452/3) as the guidance in SINQ 20140058 is still in effect. The 4th and 5th editions of the WHO Classification of Tumors of the digestive system define solid pseudopapillary neoplasm of the pancreas as a low-grade malignant pancreatic tumor. |

20230028 | Histology--Vulva: How is the histology coded for vulvar intraepithelial neoplasia III (VIN III)/Squamous cell carcinoma in situ from a pathology report of the vulva, 8070/2 for squamous cell carcinoma in situ or 8077/2 for VIN III? The rules do not discuss this particular situation. |
Assign 8077/2 for high-grade squamous intraepithelial lesion, VIN 3 in this case. The WHO Classification of Female Genital Tumors, 5th edition, states that squamous intraepithelial lesions (SILs) of the vulva are also known as vulvar intraepithelial neoplasia, HPV-associated. The term squamous cell carcinoma in situ is not recommended. |

20230040 | First Course Treatment/Hormone Therapy--Prostate: Is Lupron first course therapy in a patient who initially elected active surveillance for prostate cancer and then consented to treatment with Lupron? See Discussion. |
in March, the patient with stage cT1c, Gleason grade 7, prostate cancer elected active surveillance. In April, the patient consented to treatment with Lupron. There was no evidence of disease progression. According to the rules on page 161 of the 2023 SEER manual, we think the answer is yes, but the reporting hospital states that this is second course therapy. |
Code Lupron as second course therapy and code active surveillance as first course therapy in this scenario. The 2023 SEER Manual states to code all treatment data items to 0 or 00 (Not done) when the physician opts for active surveillance, deferred therapy, expectant management, or watchful waiting. Assign code 2 to Treatment Status. Active surveillance is not the same as "refusing treatment." Active surveillance is a valid option offered to the patient. The patient chose this option and later changed their mind. This is not a refusal of recommended treatment. Document all the details in the appropriate treatment text fields. |

20230056 | Reportability/Histology--Heme and Lymphoid Neoplasms: What is the histology code for nodular lymphocyte predominant B cell lymphoma that is never called Hodgkin lymphoma? Is it acceptable to record the histology code for nodular lymphocyte predominant Hodgkin lymphoma, (9659/3)? See Discussion. |
Patient has a history of human immunodeficiency virus and diffuse large B cell lymphoma diagnosed in 2012, and is status/post systemic therapy and in remission since completing first course treatment. In 2022, the patient has imaging suspicious for recurrence. A biopsy of a deep left cervical lymph node showed atypical lymphoid infiltrate with the comment: “This is a challenging case. The constellation of findings is most in keeping with early / focal and subtle involvement by a nodular lymphocyte predominant B-cell lymphoma. We find no evidence of involvement by a diffuse large B-cell lymphoma.” The managing physician later states, “Cervical lymph node biopsy (06/2022) was consistent with nodular lymphocyte predominant B cell lymphoma.” |
According to the 5th edition WHO Blue Book for Hematopoietic Neoplasms, Beta Version, (not released yet), nodular lymphocyte predominant B-cell lymphoma is an alternate name for 9659/3. We will update the Heme database once the 5th edition is released in print. |

20230017 | Solid Tumor Rules/Multiple Primaries--Rectum/Anal Canal: How many primaries are accessioned and how should histology be coded for a 2021 abdominoperineal resection showing invasive adenocarcinoma of distal rectum and associated Paget disease of the anal mucosa and perianal skin? See Discussion. |
The synoptic report calls this “Invasive adenocarcinoma with secondary Paget disease of anal mucosa and perianal skin.” The tumor size is listed as “2.1 x 1.7 x 0.7 cm, including associated advanced adenoma; size does not include the extent of the associated Paget disease, which extends for at least 2 cm distally.” Clinically this is called an incidentally discovered Paget’s disease. It is unclear if this is a collision tumor that should be abstracted as separate primaries, or if this is a single tumor with underlying Paget’s disease (similar to that described in Other Sites Rule H26). If this is a single rectal tumor, there does not appear to be an H rule for this scenario. |
Abstract two primaries using rule M4 of the Colon rules or rule M13 of Other Sites: 1. Invasive adenocarcinoma of distal rectum and 2. Paget disease of the anal mucosa / perianal skin (determine site of origin and code primary site accordingly). The rectum and the anus are separate sites and the histologies differ in each site. The WHO Classification of Digestive System Tumors, 5th edition, states that in addition to secondary anal Paget disease arising from anal canal adenocarcinoma, or rarely, adenoma without documented invasive disease, secondary Paget cells may be contiguous with the underlying neoplasm or manifest at different at sites distinctly away from it (with skip lesions). Document the details in the appropriate text fields. |

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. |

20230064 | Primary Site--Cervix Uteri: When no other information is available regarding the origin of the tumor, can an overlapping cervical adenocarcinoma (C538, 8140/3) be coded to the endocervix (C530) based on the histology? See Discussion. |
Adenocarcinoma is a glandular tumor and the endocervix is generally the origin of glandular tissue for the cervix. However, if the only available information is pathology proving a single tumor overlapping the endocervix and exocervix, can we code the site to C530 instead of C538? Applying the current primary site coding instructions, primary site would be coded as C538 because there is no specific statement of the tumor origin; the primary site coding instructions state the tumor is coded to an overlapping site in the absence of a specific statement of origin and there is no existing SINQ confirming the site can be assumed to be the endocervix based on the histology. |
Code Primary Site as Overlapping lesion of cervix uteri (C538). The 2023 SEER Program Coding and Staging Manual Primary Site Coding Instructions for Solid Tumors #4 says to code the last digit of the primary site code to ‘8’ when a single tumor overlaps an adjacent subsite(s) of an organ and the point of origin cannot be determined. This is also supported by the ICD-O-3, 3rd edition, note in the Topography section that states: In categories C00 to C809, neoplasms should be assigned to the subcategory that includes the point of origin of the tumor. A tumor that overlaps the boundaries of two or more subcategories and whose point of origin cannot be determined should be classified to subcategory ‘8.” |

20230042 | First Course Treatment/Surgery of Primary Site--Rectum: What surgery code should be used for laparoscopic C/T open low anterior resection with colorectal anastomosis, loop ileostomy in diagnosis year 2020, code 30 or 40? See Discussion. |
Can you provide clarification on Rectum primary surgical code 40 Pull through WITH sphincter preservation (colo-anal anastomosis)? Would this be code 30 or 40 due to the colorectal anastomosis? |
Assign code 40, Pull through WITH sphincter preservation (colo-anal anastomosis). The National Cancer Institute Dictionary of Cancer Terms defines coloanal anastomosis as a surgical procedure in which the colon is attached to the anus after the rectum has been removed. It is also called coloanal pull-through. |

20230004 | SEER Manual/Laterality--Kaposi Sarcoma: If both arms are involved with Kaposi sarcoma and no other sites, how is laterality coded? See Discussion. |
Per Solid Tumor Manual Other Sites Rule M6, despite the number of areas of involvement, any presentation of Kaposi sarcoma is always a single primary. The primary site is skin using the Kaposi Sarcoma for All Sites Coding Guidelines (Appendix C, 2023 SEER Manual). Does SEER Program Coding and Staging Manual Laterality Coding Instruction #4 preclude the use of code 4 [Bilateral involvement at time of diagnosis...] if a patient presents with KS involvement of only both arms or only both sides of the face? |
Assign Laterality code 4 (Bilateral involvement at time of diagnosis, lateral origin unknown for a single primary) in the situations you describe. Skin of upper limb and shoulder and Skin of other and unspecific parts of the face are listed as paired organs in the table Sites for Which Laterality Must Be Recorded In the 2023 SEER Manual. |

20230009 | Solid Tumor Rules/Multiple Primaries--Vulva: How many primaries are accessioned when a 2023 diagnosis of keratinizing squamous cell carcinoma (SCC) (8071/3) of the vulva follows a previous diagnosis of nonkeratinizing SCC (8072/3) of the vulva and the timing rule (M12) does not apply? See Discussion. |
Table 19: Vulva Histologies of the Other Sites Solid Tumor Rules does not include entries for either keratinizing or nonkeratinizing squamous cell carcinoma in the “Squamous cell carcinoma, NOS” row. However, these are two distinctly different histologies per the ICD-O-3.2. All other Solid Tumor Rules schemas include an M Rule instructing one to abstract multiple primaries when separate/non-contiguous tumors are two or more different subtypes/variants in Column 3 of the Specific Histologies, NOS, and Subtype/Variants Table for the schema (e.g., Rule M6 for Lung). The timing of these tumors is stated to be irrelevant. The Notes confirm the tumors may be subtypes/variants of the same or different NOS histologies and tumors in column 3 are all distinctly different histologies (even if they are in the same row). However, the 2023 Other Sites schema appears to be missing this rule. Should these distinctly different histologies be accessioned as separate primaries? Is an M Rule missing from the Other Sites schema to address distinctly different histologies? |
Table 19 is based on WHO 5th Ed Tumors of vulva and squamous cell variants, keratinizing and non-keratinizing, are no longer recommended and are excluded from the 5th Ed. HPV related terminology is now preferred for these neoplasms. Per consultation with our GYN expert pathologist, based on the information provided, this is likely a single tumor that was not completely excised in the original biopsy. A new tumor in the same site would not appear within 8 months. If you cannot confirm two separate/non-contiguous tumors were present, abstract a single primary per M1. As for histology, the tumor showed both keratinizing and non-keratinizing features and HPV status is unclear. Per our expert, code to SCC 8070/3—keratinization or lack of does not change treatment or prognosis. Even If there is proof of separate/non-contiguous tumors, our expert still feels this is a single primary coded to SCC 8070/3. Treatment does not differ by keratinization or HPV status. Coding two primaries would be incorrect and inflate incidence rates. Per our expert, this is an unusual occurrence. The rules cover 85% of cases but there will always be situations that do not fit a rule. This case is an example of that. A new GYN specific Solid Tumor Rules module is under development and a rule to address this situation could be included. |
