Urinary: Transitional Cell Carcinoma and open prostatectomy: Path from Bladder: Papillary and solid transitional cell carcinoma of bladder - grade II and III Stage A.

Path from prostatectomy: The prostatic tissue samples shows areas of urothelia carcinoma in situ - related to the tumor present in the bladder.

Conclusion: Prostatectomy showing foci of transitional cell carcinoma in situ of prostatic urethra.

Urinary bladder: Invasive urothelial carcinoma, high-grade, 4.5cm, predominantly solid type, arising in background of carcinoma in-situ, carcinoma grossly extends into perivesical adipose tissue; lymph-vascular invasion is seen.

Unlike most other sites, there is no specific code for a radical surgical procedure of a skin primary. In this case, the patient was diagnosed with a sebaceous cell carcinoma of the lower eyelid skin by punch biopsy. The tumor was large and an orbital exenteration was planned. Despite the extensive surgery performed, skin margins were less than 1 cm. Is an orbital exenteration a "major amputation" (code 60) in this case? Given that the margins were not greater than 1 cm, codes 45 - 47 (which includes a minor (local) amputation) don't seem to apply. However, if this procedure cannot be classified as "minor amputation" then doesn't it seem overkill to refer to the procedure as a "major amputation"?

An alternative would be to code Surgery of Primary Site to 32 for the skin resection (punch biopsy followed by a gross excision of the lesion, margins less than 1 cm) and code Surgical Procedure of Other Site to 2 (non-primary surgical procedure to other regional sites) to record the removal of the globe and orbit as part of the orbital exenteration. Which is correct?

Unless there is a biopsy that proves in situ tumor (EOD code 000, Tis) or extratesticular invasion into the scrotum, penis, or further contiguous extension (EOD code 700, T4), EOD Primary Tumor must be coded based on the PATHOLOGICAL assessment (orchiectomy). There are no other CLINICAL codes because the AJCC indicates imaging is not used for local T-categorization, and the EOD derives the AJCC TNM staging. If the case can not be coded to either EOD Primary Tumor codes 000 or 700 clinically, the only clinical code that seems to apply is 999 (Unknown).

We are seeing more cases treated with neoadjuvant chemotherapy prior to orchiectomy, especially in patients with distant metastatic disease. The EOD Manual indicates that clinical evidence takes priority over pathological evidencewhen neoadjuvant treatment is given, unless the extent of disease following neoadjuvant treatment is greater than pre-treatment clinical findings. If the clinical and pathological information are the same, code the extension based on the clinical information.

Do these general rules also apply to testis even though we cannot code CLINICAL findings for these tumors? If so, will EOD Primary Tumor be coded to 999 (Unknown) for any testis primary that is not in situ or invasive into the scrotum, etc., that is treated with neoadjuvant therapy? Or should the post-neoadjuvant PATHOLOGICAL assessment be coded for these tumors because the CLINICAL assessment would otherwise be unknown?

How is the EOD Primary Tumor coded for the following two cases?

1. Left testicular mixed germ cell tumor, biopsy-proven metastasis to a supraclavicular lymph node. The left testis contained a small mass on scrotal ultrasound. The patient underwent neoadjuvant chemotherapy, and the post-treatment orchiectomy proved no residual primary tumor (ypT0). Is EOD Primary Tumor 999 because it is clinically unknown (even though it was clinically limited) or 800 (No evidence of primary tumor) because there was no pathological evidence of tumor following neoadjuvant treatment?

2. Right testicular mixed germ cell tumor with biopsy-proven inguinal lymph node metastasis. There was a palpable mass in right testis on physical exam (not described as fixed or involving scrotum). The patient underwent neoadjuvant chemotherapy, and the post-treatment orchiectomy proved a residual 2 cm tumor limited to the testis without lymphovascular invasion (LVI). Is EOD Primary Tumor 999 because it is clinicallyunknown or 200 (PATHOLOGICAL assessment only - Limited to testis WITHOUT LVI)?

Under the hematopoietic data base, treatment for polycythemia vera shows chemotherapy, immunotherapy, and phlebotomy. Essential thrombocytopenia shows blood thinners, anti-clotting medications, aspirin, chemotherapy, immunotherapy, and other therapy (Anagrelide) (for essential thrombocythemia only) and watchful waiting (for asymptomatic patients). Myelodysplastic syndrome shows bone marrow transplant, chemotherapy, immunotherapy, and stem cell transplant.

SEER*RX under warfarin says: Per the 2012 Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual (page 10), blood thinners and/or anti-clotting agents are to be coded as treatment (Other Therapy) for the following histologies: 9740/4 Mast cell sarcoma 9741/3 Systemic mastocytosis 9742/3 Mast cell leukemia 9875/3 Chronic myelogenous leukemia BCR/ABL 1 positive 9950/3 Polycythemia vera 9961/3 Primary myelofibrosis 9962/3 Essential thrombocythemia 9963/3 Chronic neutrophilic leukemia 9975/3 Myelodysplastic/myeloproliferative neoplasm, unclassifiable.

Under the Grade section in the Heme DB for anaplastic large cell lymphoma, NOS it indicates the following:

"Grade - Code grade specified by pathologist. If no grade specified, code 9."

There is no reference in the Grade section that we should look at the Abstractor Notes or a specific Module in the Heme DB for additional information. However, in the Abstractor Notes section it states, "Grade is T-cell (5) unless pathologist specifically designates as a B-cell (see G2 rule)." These two statements are conflicting. Which is the correct grade?

Treatment for estrogen receptor positive (ER+) breast cancer started with tamoxifen (non-steroidal estrogen subcategory) and switched to letrozole (non-steroidal aromatase inhibitor subcategory). Patient being treated with immunotherapy, Avastin (cytostatic agent-antiangiogenesis agent subcategory), and then changed to Atezolizumab (monoclonal antibody subcategory).

Is Atezolizumab a new course of therapy because it is a different subcategory?

Transurethral resection: Microscopic Diagnosis: Bladder, transurethral resection: Low-grade papillary urothelial carcinoma Gross Description: Received in formalin labeled with the patient's name and bladder tumor is a 3.0 x 2.0 1.0 cm aggregate of friable tan tissue biopsies. The specimen is submitted in toto, cassettes

This is all the information there is on this path report. Extent of Disease (EOD) instructions state inferred description of noninvasive: No statement of invasion (microscopic description present) SEER 2018 Appendix C Bladder Coding Guidelines state code behavior 3 if the only surgery performed is a transurethral resection of the bladder (TURB) documenting that depth of invasion cannot be measured because there is no muscle in the specimen OR the pathology report does not mention whether the submucosa is free of tumor or has been invaded by tumor.

Total thyroidectomy Final Diagnosis: Papillary carcinoma, classical type, with papillary and follicular architecture.

The 2007 MP/H rules state that the term architecture is reserved for coding subtype of in situ primaries only. However, SINQ 20130165 appears to indicate this should be coded for invasive thyroid subtypes as well. Can you confirm the addition of the term architecture for determining an invasive histologic subtype for thyroid?

Tonsillectomy and bilateral radical neck dissections were done. The path diagnosis was left and right tonsils: squamous cell carcinoma, bilateral tonsils with negative inked surgical margins of resection. Physical exam and operative findings did not mention any extension beyond the tonsils.

We originally coded the EOD-Extension field to 30 for a bilateral tonsil primary. The case failed the SEER Edit IF41 (Primary Site/Lat/EOD). According to that edit, if laterality is 4 then the EOD-Extension field must not be 00 through 30.

We recoded the EOD-Extension field to 99 in order to comply with the SEER edit.
