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?

Please comment on these specific scenarios.

1. A prostate biopsy is suspicious for adenocarcinoma, but the urologist is not considering this malignant, nor is the urologist treating for malignancy, but there is no clear statement from the physician that this is not reportable.  Should this case be abstracted?
2. A prostate biopsy is suspicious for adenocarcinoma, and there is a statement by the physician that this is not yet malignant. Should this case be abstracted?
3. Prostate MRI with PIRADS 4 or 5; however, the treating urologist does not call this malignant and is not treating patient for prostate cancer.  [Example: 2024 Prostate MRI - PI-RADS 4. Follow up with Urologist states patient to repeat Prostate MRI in 1 year and continue with yearly PSA levels and there is no mention of prostate cancer other than the PI-RADS score]. Should this case be abstracted?

We are aware that the WHO 4th edition for urinary tumors has changed the behavior of “clear cell papillary renal cell carcinoma” to /1 but registries are to continue collecting as /3.

While the diagnosis in our case is stated as “tumor” it does seem like the pathologist may be using the new WHO terminology of “tumor” rather than “carcinoma,” so we are not sure if behavior is /3 or /1.

Rule M15

Abstract a single primary when synchronous, separate/non-contiguous tumors are on the same row in Table 2 in the Equivalent Terms and Definitions.

Note: The same row means the tumors are

• The same histology (same four-digit ICD-O code) OR

• One is the preferred term (column 1) and the other is a synonym for the preferred term (column 2) OR

• A NOS (column 1/column 2) and the other is a subtype/variant of that NOS (column 3) OR

• A NOS histology in column 3 with an indented subtype/variant

Example: TURBT shows invasive papillary urothelial carcinoma 8130/3 and CIS/in situ urothelial carcinoma 8120/2. Abstract a single primary. Papillary urothelial carcinoma and urothelial carcinoma are on the same row in Table 3.

It appears there was some confusion about finding this new malignant HGAP tumor (2023+) code. If this is not a specific subtype/variant of astrocytoma, can clarification be added to the “New for 2023” entry for HGAP?

The SEER Manual seems to give somewhat conflicting instructions for clinical trial therapies under the Neoadjuvant Therapy data item. One section states that limited systemic therapy may occur in clinical trials to impact the biology of a cancer, but is not a full course of neoadjuvant therapy with the intent to impact extent of surgical resection or other outcomes (organ preservation, function or quality of life); do not code as neoadjuvant therapy for the purposes of this data item. Then another section states for purposes of this data item, the criteria for neoadjuvant therapy include that treatment must follow recommended guidelines for the type and duration of treatment for that particular cancer site and/or histology, and that neoadjuvant therapy may be given as part of a clinical trial.

For example, a patient was diagnosed with invasive ductal carcinoma of the breast, 6 cm in size; treatment planning conference recommended neoadjuvant chemotherapy. The patient elected to participate in a clinical trial and was assigned to a group given the antibody drug conjugate datopotamab deruxtecan (Dato-DXd) plus durvalumab for 12 weeks. There was no physician documentation of intent or expected outcomes, nor yC staging or statement of clinical response. Post-therapy imaging showed no residual mass, and post-therapy mastectomy path report showed only residual ductal carcinoma in situ, stating "Treatment Effect (after neoadjuvant): Residual Cancer Burden - pCR, In the breast - complete response."  The medical oncologist stated post-therapy stage was ypTis ypN0 cM0.

The trial drugs this patient were given do not appear to be approved or standard neoadjuvant/pre-operative drugs in SEER*Rx or NCCN guidelines for this type of cancer; however, the duration of treatment was fairly substantial, and although we don't have clear documentation from physicians as recommended in the SEER manual (which is usually not stated, in our experience), it seems like they may be considering it as neoadjuvant therapy. How should the Neoadjuvant Therapy data item be coded for cases like this? What is the best way to differentiate between clinical trial therapies that are "limited systemic exposure" (code 3) versus true neoadjuvant therapy (code 1)?

The ICD-O-3.2 indicates histology 8051 only applies to diagnoses of condylomatous carcinoma and warty carcinoma made prior to 2018. For penis cases diagnosed 2018 and later, these neoplasms should be coded as 8054. This is consistent with SINQ 20200003.

However, a new Table was added to the Other Sites schema in the 2024 Solid Tumor Rules update. Table 23 lists “Verrucous carcinoma / carcinoma cuniculatum / Warty carcinoma” as histology 8051. While verrucous carcinoma is still listed under histology 8051 in the ICD-O-3.2, warty carcinoma is not.

Does Table 23 need to be updated? Or is this an error in both the ICD-O-3.2 and SINQ 20200003?

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.

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?

Additional comments in this pathology report state "The entire case was sent in consultation to an ophthalmic pathologist. [Pathologist] assigns a conjunctival melanocytic intraepithelial neoplasia (C-MIN) score of 2-3 due to the upward pagetoid migration of small, dendritic melanocytes. A C-MIN score of 2-3 is between low-grade conjunctival melanocytic intraepithelial lesion (LG-CMIL; C-MIN 2) and high-grade conjunctival intraepithelial lesion (HG-CMIL; C-MIN 3). The older terminology for this lesion would be primary acquired melanosis (PAM) with mild to focally moderate atypia."

This term does not appear in the SEER Program Coding and Staging Manual (SPCSM), Appendix E1 of the SPCSM, or Solid Tumor Rules (specifically rule H3) .
