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.

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.

A change in the subcategory for a hormone drug does not indicate the end of First Course of Treatment because different hormone therapies generally achieve the same result. For example, some forms of breast cancer are estrogen-dependent and the various subcategories of hormone drugs used to treat them, such as gonadotropin-releasing factor agonists, aromatase inhibitors and estrogen antagonists, all achieve the same result - to block estradiol effects in these tumors.

Similarly, a change in immunotherapy is not a new course of treatment.

The instruction in the SEER Manual is specific to chemotherapy. Chemotherapy is the only systemic treatment for which a change in the subcategory of a drug indicates the end of First Course of Treatment, due to the fact that different chemical agents damage cancer cells in different ways and at different phases in the cell cycle.

EOD follows AJCC criteria in this situation and we have confirmed with AJCC that Stage T2a (superficial muscle) and Stage T2b (deep muscle) cannot be assigned when only a TURB is done.

For EOD Primary Tumor, Bladder, codes 200, 250, 300, 350, can only be used when

• Cystectomy is performed
• Muscularis propria is involved, AND
• Pathology report states superficial muscle (200, 250) or deep muscle (300, 350) is involved

If a TURB is done and there is mention of the muscularis propria invasion (superficial muscle or deep muscle), use EOD codes 370 or 400. If a TURB is done and the pathology report states superficial or deep muscle, ignore and coded as “invasion of muscularis propria, NOS” (EOD codes 370 or 400).

Instructions and code descriptions for EOD Primary Tumor have been updated to indicate this. These updated instructions and code descriptions will be available when SEER*RSA is updated for 2024, Version 3.1 (Sept/Oct 2023). These updates are included here for reference and can be applied for cases diagnosed 2018+.

Use the histology codes SCC, HPV-associated (8085/3) and SCC, HPV-independent (8086/3) only when HPV testing is done on that specimen.  Do not use previous HPV tests to code the histology.

Code as SCC, NOS (8070/3) in both examples as no HPV testing was performed on the LEEP procedure specimens that identified the SCC.

Assign code 1 in Surgical Procedure of Other Site (NAACCR #1294) when a simple bilateral mastectomy is performed for a single tumor involving both breasts. This statement was inadvertently omitted from the STORE manual and will be added back in: For single primaries only, code removal of contralateral breast under the data item Surgical Procedure/Other Site (NAACCR Item #1294) or Surgical Procedure/Other Site at This Facility (NAACCR Item #674).

The information presented by NAACCR was intended to be consistent with what is in the SEER manual. It may have been misuderstood.

Assign 8140/3 (adenocarcinoma, NOS). WHO has not yet recognized the variant amphicrine prostate carcinoma and have not proposed an ICD-O code for this neoplasm. Document information in a related text field.

Assign code 9702/3 for  EBV+ nodal T- and NK-cell lymphoma. Primary nodal EBV-positive T- or NK-cell lymphoma is a rare lymphoma type introduced in the 2017 WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues (4th Ed.) as a variant of peripheral T-cell lymphoma (PTCL). It  presents more commonly in elderly and/or immunodeficient patients, lacks nasal involvement, and is more often of T-cell rather than NK-cell lineage. 

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.

Rule M1 applies because we don't know if there are separate tumors or separate foci within a single tumor. This is a single primary coded 8140/3. The prostate rules will be reviewed for an addition to cover this situation.
