For example:

-ultrasound of the right eye: consistent with a nevoma/melanoma; we could not find any indication that nevoma is a reportable term

-bladder biopsy pathology report:  severe urothelial dysplasia/carcinoma in situ (CIS)

As a central registry, we receive some limited information cases like this where there is no record of treatment or possibility to follow-back to physicians for clarification, so we want to make sure we are reporting them correctly.

Acinar predominant adenocarcinoma measures at least 12 mm and involves wedge biopsy margins, while the lepidic predominant adenocarcinoma measures 11 mm and does not involve the margins of that separate specimen. Pathologist also notes, “CT findings of diffuse coarse reticular nodular opacity, these findings may represent pneumonic type adenocarcinoma/diffuse pulmonary involvement or intrapulmonary metastasis.  Both of these scenarios have the corresponding stages of pT4 (if thought to be ipsilateral) or M1a (if thought to also involve the contralateral lobe).”

Patient declined any further treatment and transitioned to hospice before expiring less than 1 month after wedge biopsies.

It is unclear if Rule M6 would apply to these two specimens with different subtypes since this scenario is not specifically addressed in the M rule definitions.

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.

2021-Right pleural fluid:  Negative for carcinoma.

5/18/2021: Right iliac crest bone marrow core biopsy, aspirate smear, clot section and peripheral blood smear:  Hypercellular bone marrow, morphological findings are suspicious for a myeloproliferative neoplasm. Flow Cytometry: Slight immunophenotypic abnormalities of the myeloid cells. No abnormal B cell, T cell, or NK cell populations identified. Normal female karyotype. KARYOTYPE: 46,XX[20]. Negative for deletion of 13q14.3 (D13S319) by FISH. Negative for deletion of 13q34 (LAMP1) by FISH. Negative for hyperdiploidy involving chromosome 9 by FISH. Negative for t(9;22)(q34;q11.2) by FISH. Negative for deletion of the EGR1 gene on 5q31 by FISH. Negative for monosomy 5 by FISH. Negative for deletion of 7q31 by FISH. Negative for monosomy 7 by FISH. Negative for deletion of 20q12 by FISH. Negative for trisomy of chromosome 8 by FISH.

6/4/21-Left adrenal; biopsy: poorly-differentiated malignant neoplasm with extensive necrosis. Immunohistochemical stains show the neoplastic cells to be negative for CK7, TTF-1 and p63. Negative CK7 and TTF-1 would argue against a lung primary. Correlation with clinical and radiological findings is advised.

We are unable to contact the provider.

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?

The 2023 SEER Manual instructions contain a new note in Hematologic Transplant And Endocrine Procedure, Coding Instruction 6, regarding bilateral salpingo-oophorectomy (BSO) when performed for hormonal effect for breast, endometrial, vaginal, and other primary cancers. While we have observed BSO being performed for breast primaries, we do not recall ever seeing a statement for endometrial or vaginal primaries regarding a “BSO being done as hormonal manipulation” when scheduled either with or without a hysterectomy being performed simultaneously. As a result, we are not clear exactly when a BSO would be captured in the Hematologic Transplant And Endocrine Procedure field for these gynecologic primary sites.

Also, if these types of procedures are Hematologic Transplant And Endocrine Procedures, are they also captured and coded in the Surgery of Primary Site codes that directly relate to those same organs? Does timing have any effect on the coding of either field?

The final diagnosis on bone marrow biopsy was high grade myeloid stem cell neoplasm, 17% blasts by differential count.  The pathologist further states that this could be classified as “MDS with increased blasts (MDS-IB2) per the WHO 5th edition classification, or MDS/AML per the international consensus classification (ICC).”  FISH and cytogenetics revealed a loss of 7q, but no other AML-related genetic abnormalities. The physician confirms the patient has MDS/AML.

Serous borderline tumor–micropapillary variant (8460/2, C569) was included in the ICD-O-3 Behavior Code/term updates effective 1/1/2018 but marked as Not Reportable for 2018.

There have been multiple additional updates to the ICD-O but no further clarification as to the reportability of this histology. ICD-O-3.2 currently lists serous borderline tumor, micropapillary variant (C569) as 8460/2 with no mention of reportability and no information provided in Includes/Excludes.

SINQ 20220032 instructs capturing this histology as reportable when diagnosed 1/1/2021 or later and occurring in the testis. The answer indicates this is reportable due to the /2 behavior code in ICD-O-3.2, but it does not specify that it is limited to specific sites.

Is serous borderline tumor, micropapillary variant reportable for ovary? If so, what dates apply? Is serous borderline tumor, micropapillary variant of the testis diagnosed after 1/1/2021 reportable?

The resection pathology report final diagnosis indicates this is both mixed mucinous and non-mucinous with a lepidic predominant component. The pathologist notes this is “Lepidic: 75%. Acinar: 25%.”  The percentage of the mucinous component is not documented.

Rule H1, Note 1, states “When mucinous carcinoma is mixed with another histology, such as adenocarcinoma and mucinous carcinoma, code mucinous ONLY when mucinous is documented to be greater than 50% of the tumor.” While mixed invasive mucinous and non-mucinous carcinoma is included in Table 2 (Combination/Mixed Histology Codes) without a required percentage, it is unclear whether one should move past Rule H7 and use Rule H8 to code this combination histology code. Rule H7 would instruct one to code the histology to lepidic adenocarcinoma (adenocarcinoma, lepidic predominant) based on the percentage of the lepidic component in the tumor. However, this does not address the mixed mucinous and non-mucinous diagnosis. Which H Rule and histology apply to this case?

Example #1: Cervix loop electrocautery excision procedure (LEEP) pathology: Histologic Type: Squamous cell carcinoma, HPV-associated. Histologic Type Comments: High-risk HPV testing on previous Pap test sample reported as positive for high-risk HPV. The prior Pap diagnosis was HSIL only with molecular results positive for high-risk HPV.

Example #2: Cervix endocervical curettage and biopsy with CIN 3, p16 diffusely positive. Subsequent LEEP with superficially invasive squamous carcinoma (no HPV or p16 testing done). This was followed by an additional cone excision that was negative for residual malignancy and p16 testing was also negative.
