Assign as Stage IV as recommended by our expert hematological oncologist. This is a rare occurrence and this type of presentation does not fit the definition of intraocular extension. Stage IV is probably the best stage for this type of presentation, since there are two extranodal organs involved, even though they involve a bilateral site.

EOD Primary Tumor: 700

SS: 7 (Distant)

NTRK-rearranged spindle cell neoplasm is a newly identified variant of sarcoma; however, WHO has not yet proposed a specific ICD-O code for this rare neoplasm. Code to spindle cell sarcoma (8801/3).

WHO defines NTRK-rearranged spindle cell neoplasm as an emerging group of molecularly defined rare soft tissue tumors that span a wide group of morphologies and histological grades, and are most often characterized by a spindle cell phenotype among other characteristics.

Code alcohol ablation under Surgery of Primary Site 2023. Code alcohol embolization as Other Therapy when tumor embolization is performed using alcohol as the embolizing agent.

Alcohol ablation, also known as an ultrasound-guided percutaneous ethanol injection (PEI); is treatment that involves injecting concentrated alcohol directly into the tumor. Embolization uses special techniques to close off blood flow by introducing special medications or using other techniques designed to block blood vessels. Types of embolization are arterial embolization as with alcohol (ethanol), chemoembolization, and radioembolization. Refer to the current SEER Program Coding and Staging Manual when assigning surgery and embolization procedures.

Report intracholecystic papillary neoplasm (ICPN) with high-grade dysplasia (8503/2) of the gallbladder.

According to the 5th edition WHO Blue Book for Hematopoietic Neoplasms, Beta Version, (not released yet), nodular lymphocyte predominant B-cell lymphoma is an alternate name for 9659/3. We will update the Heme database once the 5th edition is released in print.

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+.

As a general rule, the surgeon is usually in a better position to determine the site of origin compared to the pathologist. The surgeon sees the tumor in its anatomic location, while the pathologist is often using information given to him/her by the surgeon and looking at a specimen removed from the anatomic landmarks. However, when a pathologist is looking at an entire organ, such as the pancreas, he/she may be able to pinpoint the site of origin within that organ.

In the case of pancreas body vs. neck, the neck is a thin section of the pancreas located between the head and the body. It may be a matter of opinion whether a tumor is located in the "body" vs. the "neck." In the situation you describe, we would give preference to the surgeon and assign the code for body of pancreas, C251.

Assign code 8891/3 (epithelioid leiomyosarcoma) as cells were described as have an epithelioid morphology; whereas, myxoid was used as a descriptive term and not a specific histologic type.

Pituitary microadenoma is reportable. Assign 8272/0. "Micro" refers to size of the adenoma. 

Per the SEER Program Coding and Staging Manual 2022, a reportable intracranial or CNS neoplasm identified only by diagnostic imaging is reportable, and "consistent with" is listed on the Ambiguous Terms to be used for Reportability list. As a result, this case is reportable.

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.
