Do not report this case of "adenocarcinoma spectrum lesions" based on the information provided in the absence of a more specific diagnosis. Do not report until/unless a definitive diagnosis of malignancy is made. "Adenocarcinoma spectrum lesion" covers a continuum of lung neoplasms from preinvasive lesions (atypical adenomatous hyperplasia and adenocarcinoma in situ) to invasive lesions (minimally invasive adenocarcinoma and invasive adenocarcinoma).

Should additional information become available, report the case and assign the histology code if a more specific histology is confirmed later. Use text fields to record the details.

Report these high grade dysplasia of the following organs as stated below.

Stomach: Assign code 8148/2 glandular intraepithelial neoplasia, high grade using the Other Sites Solid Tumor Rules, Table 6: Stomach Histologies and as described in the WHO Classification of Digestive Tumors, 5th edition.

Small intestine and Esophagus: Assign code 8148/2 glandular intraepithelial neoplasia, high grade, using the Other Sites Solid Tumor Rules, Other Sites Histology Rules, Rule H4/H26. The following note is listed for both of these rules.

Note: This list may not include all reportable neoplasms for 8148/2. See SEER Program Coding and Staging Manual or STORE manual for reportable neoplasms

The Other Sites Solid Tumor Rules, Table 5: Esophagus Histologies and Table 7: Small Intestine and Ampulla of Vater Histologies will be updated to reflect this code as time permits.

Code SEER Summary Stage 2018 to Localized, Code 1. Per consult with AJCC and noted in the Primary Peritoneal Chapter in AJCC 8th edition, an intraoperative rupture is coded as a surgical spill. 

A capsule rupture is when the capsule ruptures prior to the surgery (Summary Stage Regional, Code 2). 

If you are unable to follow up with the physician, do not report this case until or unless more information becomes available.

1) Do not infer the percent of viable tumor if only percent of necrosis is provided. For the example, assign code 6 when Neoadjuvant therapy was completed and the treatment effect in the breast is stated only as “Present".

2) Do not use the residual cancer burden (RCB) score from the pathology report to code the Neoadjuvant Therapy--Treatment Effect field for breast cancer. We do not have a crosswalk from RCB to neoadjuvant Therapy--Treatment Effect.

RCB index is an accurate and reliable tool to assess patient prognosis. RCB is estimated from routine pathologic sections of the primary breast tumor site and the regional lymph nodes after the completion of neoadjuvant therapy. The data item Neoadjuvant Therapy--Treatment Effect records information on the primary tumor only.

Document information in a text field in both examples.

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 17 for irreversible electroporation ablation of the prostate when there is no tissue submitted to pathology for a 2021 or 2022 case.

Assign code A170 for a 2023 case.

Code the Date of First Surgical Procedure as 01/01/2023 in the example provided where the shave biopsy is followed by wide excision. Beginning in 2023, significant changes were made in that shave, punch, and elliptical biopsies are coded as surgical procedure regardless of margin status. Appendix C Skin Surgery Codes state that an incisional biopsy would be a needle or core biopsy of the primary tumor.

Please see Appendix M: Case Studies for Coding Melanoma in STORE v23, Case study 2: Shave Biopsy followed by WLE (page 412), for an explicit example of how to code your example case.

We will clarify this in the upcoming release of the SEER manual,

Your case is equivalent to encapsulated follicular variant of papillary thyroid carcinoma, non-invasive (non-invasive EFVPTC) and is not reportable for cases diagnosed in 2021 or later even though it says "carcinoma." That is because the WHO assigned a behavior code of /1 to this entity (8349/1). NIFTP is assigned to the same histology and behavior code.

Report as squamous cell carcinoma (8070/3) on the basis of “microscopic focus suspicious for superficial invasion.” "Severe dysplasia" is equivalent to "high grade dysplasia" in the Head and neck. As such, "severe squamous dysplasia" would be coded to 8077/2. However, in combination with the statement of "with microscopic focus suspicious for superficial invasion,” report as squamous cell carcinoma (8070/3) based on “microscopic focus suspicious for superficial invasion.” The 2023 SEER Manual instructs us to code the behavior as malignant (/3) if any portion of the primary tumor is invasive no matter how limited, i.e., microinvasion. Use text fields to record the details.
