10/2017 Bladder cancer diagnosed as invasive papillary urothelial bladder carcinoma (8130/3) (submucosal invasion).

12/2017 Surveillance scope and transurethral resection of bladder tumor (TURBT) finds “recurrent” bladder tumor, non-invasive papillary urothelial bladder carcinoma (8130/2) - same primary per 2007 Multiple Primaries/Histology, Rule M6, (both papillary urothelial bladder carcinomas).

4/2018 Radical nephrectomy found focally invasive urothelial carcinoma (8120/3) in the renal pelvis.

Is this a new primary per 2018 and forward STR, Rule M6, because it was more than 60 days since the 12/2017 in situ bladder recurrence? Or would one compare the 2018 diagnosis to the original invasive bladder tumor in 10/2017, and continue on to Rule M11, which says to abstract a single primary for urothelial carcinomas in multiple organs, regardless of behavior?

SINQ #20120080 said to compare to the original diagnosis and disregard intervening recurrences, but that pertained to the 2007 MP/H rules. Does this still apply for 2018 forward? STR, Rule M10, Note 3, states when there is a recurrence within three years of diagnosis, the “clock” starts over. The time interval is calculated from the date of last recurrence. Comparing each recurrence for urothelial carcinomas using Rule M6 could result in over-counting them. Can the instructions on how to calculate the 60-day interval be clarified in Rule M6?

Lung cancer, 2022

12/1/2022 PET/CT showed destructive hypermetabolic bone lesions in right frontal and left posterior calvarium. Left posterior calvarium lesion involves portions of left parietal and temporal bones w/invasion of mastoid air cells.

1/4/2023 MRI Brain showed large destructive mass involving left posterior temporal calvarium that extends into left mastoid region and may invade left distal transverse sinus.

2/8/2023 Radiation Oncology follow-up note: MD states there are extensive calvarium metastasis with the left parietal lesion invading the brain causing edema and MS-like changes.

2/13/23 Radiation Oncology Final Letter- Patient was treated with 1 EBRT fraction aimed at brain/skull before enrolling in hospice.

A. Left nasal mass: Sinonasal glomangiopericytoma B. Additional left nasal mass: Sinonasal glomangiopericytoma

Is this a borderline tumor? I am unable to find in this in the ICD-O-3 purple book or the Head and Neck Solid Tumor Rules.

Starting for cases diagnosed in 2024, the SPCSM manual no longer requires the data items for clinical and pathologic tumor size.  Instead, it appears to align with the CoC data item of Tumor Size Summary.  The two manuals contradict each other when it comes to coding tumor size summary for neoadjuvant chemotherapy (NAC) treated cancers.  

STORE states: "If neoadjuvant therapy followed by surgery, do not record the size from the pathologic specimen. Code the largest size of the tumor prior to neoadjuvant treatment; if unknown code size as 999."  

2024 SPCSM states "If neoadjuvant therapy followed by surgery, do not record the size from the pathologic specimen. Code the largest size of the tumor prior to neoadjuvant treatment; if unknown code size as 999." It continues to state     

 12. Assign code 000 when…. (a) no residual tumor is found…(i) Neoadjuvant therapy has been administered and the resection shows no residual tumor &

14. Assign code 999 when...(d) Neoadjuvant therapy has been administered and resection was performed. Do not use a post-neoadjuvant size to code pathologic tumor size; however, you may use the clinical tumor size if available

It seems that we will lose the value of the tumor size summary if we code 000 when NAC is administered and there is no residual disease. 

Example: Patient has a 90 mm triple positive breast tumor and is treated with neoadjuvant TCHP (docetaxel/carboplatin/ trastuzumab/pertuzumab). After completing neoadjuvant therapy, the patient has a mastectomy with no residual disease noted on the final pathology report. 

Using the 2024 SPCSM instructions, code 000 for Tumor Size Summary instead of 090 for the clinical tumor size of 90 mm tumor noted before NAC was administered. This has the potential to affect data analysis, research, and clinical trial accrual.

We would like to confirm that the correct histology code is 9431/1 per ICD-O-3.2, as the Non-Malignant CNS Solid Tumor Manual lists the histology code as both 9431/1 (pages 301 and 303 of the combined manual), but also shows it as a synonym for 9421/1 – Diffuse astrocytoma, MYB- or MYBL1 altered (page 304).

Example: Patient has a 04/2023 diagnosis of symptomatic anemia not responsive to Retacrit. Further testing includes diagnostic bone marrow biopsy 10/2023 proving MDS with low blasts and SF3B1 mutation, treated with Relozyl (Luspatercept).

There is no SEER*Rx listing for Reblozyl or Luspatercept. Per web search, Luspatercept, sold under the brand name Reblozyl, is a medication used for the treatment of anemia in beta thalassemia and myelodysplastic syndromes.

Is this non-cancer directed treatment since it is given to address the anemia rather than the MDS? If cancer-directed treatment, how should it be coded?

The 2024 Solid Tumor Rules, Table 5: Tumors of the Oropharynx, Base of Tongue, Tonsils, Adenoids contain notes that say beginning 1/1/2022, keratinizing or non-keratinizing SCCs, HPV positive or HPV negative, are coded 8085 or 8086, respectively, for sites listed in the Head and Neck Solid Tumor Rules, Table 5 only.

Table 5 introductory section also states for cases diagnosed 1/1/2023 forward: “When the diagnosis is a subtype/variant of squamous cell carcinoma and HPV status is also noted, code the subtype/variant.” This latter instruction is also included in Other Sites Table 23 (Penis and Scrotum Histologies) as a “Penis Coding Note.”

Do these instructions ONLY apply to sites on those tables (and only to Penis or to Scrotum also in Table 23)? How should we code HPV-related keratinizing/non-keratinizing or other subtype/variant SCCs, for sites NOT on those tables, given the fact that only the more common histologies are listed in the Solid Tumor tables? For example, we recently reviewed a case with HPV-positive basaloid squamous cell carcinoma of the anus (C21.0).

Laryngeal intraepithelial neoplasia II-III is not included in the ICD-O-3.2 and, while the SEER Program Coding and Staging Manual (SPCSM) confirms this is reportable, neither the SPCSM nor the Solid Tumor Rules Manual provide the specific histology to use for LIN II or LIN III. Should this be coded as 8077/2 since this is most like a high grade squamous dysplasia?

Appendix E1 in both the 2023 and 2024 SEER Program Coding and Staging Manual (SPCSM) lists these malignant spindle cell neoplasms, consistent with atypical fibroxanthoma, as reportable when other tumors have been ruled out with immunohistochemistry. This contradicts both SINQ 20190102 and the Solid Tumor Rules (STRs) general instructions indicating ambiguous terminology (e.g., “consistent with”) cannot be used to code the more specific histology when there is a NOS (malignant spindle cell neoplasm, 8004/3) and a more specific (malignant atypical fibroxanthoma, 8830/3) histology.

These tumors are typically diagnosed and treated in dermatology offices, so further chart review or confirmation by a physician is not possible for central registries.

As non-melanoma skin primaries are included in the Other Sites schema, and this schema was updated for cases diagnosed 2023 and later, which instruction applies to 2023+ diagnoses? Should these continue to be collected per Appendix E1 despite the conflict with the STR Manual and SINQ? If these are reportable, should the SINQ and STR Manual be updated to reflect this? Or should these be non-reportable per the STR Manual and SINQ?
