Reportability/Histology--Anus:  Are 2021 diagnoses of anal intraepithelial neoplasia (AIN) II or AIN II-III reportable in patients with a known history of AIN II or AIN II-III diagnosed prior to 2021? See Discussion.

Patient has a history of AIN I/low-grade squamous intraepithelial lesion (LSIL) dating back to at least 2015, was diagnosed with AIN II-III in 12/2019, and then diagnosed again with AIN II-III in 08/2021. There is no indication of treatment or a disease-free interval for this patient.

SINQ 20210015, while not an exact match to this case, implies there is no clear disease-free interval for these AIN diagnoses, so it is the same non-reportable neoplasm diagnosed prior to reportability (12/2019). However, there was a diagnosis of a reportable neoplasm in 2021, so it also seems possible this would be accessioned as a reportable tumor based on a diagnosis of reportable tumor diagnosis in 2021.

With the reportability changes for these intraepithelial neoplasia II/II-III tumors, these situations will arise more frequently.

Report AIN II and AIN II-III cases when initially diagnosed in 2021 or later.  Do not report retrospective cases; that is, cases with diagnoses prior to 2021 with continuation of AIN II or AIN II-III extending into the reportable period.

Solid Tumor Rules (2018, 2021)/Histology--Cervix:  For cases diagnosed 1/1/2022 and later, how is histology coded for the following three cervix cases relating to p16? See Discussion.

The 2022 SEER Manual indicates the p16 status (positive or negative) can be used to code more the specific histology for squamous cell carcinoma, human papilloma virus (HPV) positive (8085) and squamous cell carcinoma, HPV negative (8086). However, the histology coding instructions in the Other Sites schema have not been updated and the 2022 SEER Manual does not cover all situations commonly encountered in the registry. Does the clarification regarding p16 apply to these other situations?

  1. How is histology coded when the final diagnosis of the most representative specimen is adenocarcinoma (NOS), but the immunohistochemistry is p16 negative? Is this adequate to code histology to 8484/3 (adenocarcinoma, HPV-independent, NOS)? The pathologist did not specifically indicate this was HPV-independent adenocarcinoma, and the clarification in the 2022 SEER Manual does not include this more specific adenocarcinoma histology.
  2. How is histology coded when the Pap smear is positive for squamous cell carcinoma, p16 positive, but the most representative specimen from the primary tumor (the subsequent cervix biopsy) is only stated to be squamous cell carcinoma (NOS)? The p16 studies were not repeated on the most representative specimen, and the existing 2007 Multiple Primaries/Histology (MP/H) General Rules indicate to code the histology from the most representative specimen over a cytology report. Following the existing 2007 MPH General Rules, the histology should be 8070 (squamous cell carcinoma, NOS). However, this does not account for the p16 status of the tumor.
  3. How is histology coded when a biopsy of a metastasis (e.g., a lymph node metastasis) proved squamous cell carcinoma, p16 negative, but a subsequent biopsy of the primary cervix tumor proved squamous cell carcinoma (NOS) without additional IHC studies? Again, the 2007 MP/H General Rules confirm the primary site specimen should be used to code the histology, resulting in a diagnosis of 8070 (squamous cell carcinoma, NOS), but this ignores the p16 status of the tumor.

For cases diagnosed beginning 1/1/2022, assign histology based on new codes and terms for the examples of cervical cancer using the available p16 results as follows.

1.  Adenocarcinoma, HPV-independent, NOS (C53._) (8484/3)

2.  Carcinoma, squamous cell, HPV-associated (C53._) (8085/3)

3.  Carcinoma, squamous cell, HPV-independent  (C53._) (8086/3)

The 2022 SEER Manual states: Beginning with cases diagnosed 01/01/2022 forward, p16 test results can be used to code squamous cell carcinoma, HPV positive (8085) and squamous cell carcinoma, HPV negative (8086).  Use the available results as the rules for Other Sites have not been updated yet. The SSDI Manual data item p16 for Cervix schema also states that p16 is based on testing results and not a physician statement.  We can address these situations in a future version of the Solid Tumor Rules. The Other Sites rules will provide document priority when coding hsitology: biopsy vs. resection, cytology vs. histology, primary site vs. mets or regional site.

Solid Tumor Rules (2022)/Histology--Bladder:  Can the term configuration be used to code the more specific histology for bladder primaries diagnosed 2022 and later? See Discussion.

In the September 2021 Urinary Sites Solid Tumor Rules update, the term configuration was removed from the “DO NOT CODE histology when described as” list. However, it was not added as a term that can be used to code the more specific histology for urinary tumors.

Can configuration be used to code the more specific histology 8130 (papillary urothelial carcinoma) when the diagnosis is urothelial carcinoma, tumor configuration: papillary?

Beginning with cases diagnosed 1/1/2022, the term "configuration" can be used to code histology for urinary sites only. At the request of the AJCC urinary experts, the instructions were changed to allow configuration to be used to code histology.

Solid Tumor Rules (2018/2021)/Multiple Primaries--Skin Cancer:  How many primaries are assigned for sebaceous carcinomas using the Solid Tumor/Multiple Primaries/Histology Rules?  Does this scenario represent eight separate primaries?  See Discussion.

Details

4/15/2018:  Right abdominal wall mass excision: infiltrating sebaceous carcinoma.  Noted to have a history of Muir-Torre/Lynch syndrome.

1/21/2019:  Two left upper back mass excisions and two lower back (laterality not specified) mass excisions: infiltrating sebaceous carcinomas

8/7/2019:  Excision of multiple sebaceous carcinomas from the right posterior back, left posterior thigh, left anterior abdominal wall, left anterior thigh, right scrotum, right lower abdominal fold, all positive for sebaceous carcinoma on pathology report

9/30/2020:  Right gluteal mass, left gluteal mass, back (NOS) excisions: sebaceous carcinomas.  

10/14/2020:  Right back excision: sebaceous carcinoma. Op note:  History of Lynch syndrome with multiple sebaceous carcinomas, recurrent back mass, site of prior mass resection.

10/18/2021:  Right thigh excision: sebaceous carcinoma

Proposed primaries using MP/H Other Sites Rules

#1:       4/15/2018:  C445-1

#2:       1/21/2019:  C445-2, separate from #1 per M8, same as 1/21/19 C445-9 per M18

#3:       8/7/2019:  C445-1, separate from #1 per M10, separate from #2 per M8

#4:       8/7/2019:  C447-2, separate from #1 & #3 per M8, separate from #2 per M12

#5:       8/7/2019:  C632, separate from #1 per M10, separate from #2-#4 per M11

#6:       9/30/2020:  C445-2, separate from #1 & #3 per M8, separate from #2, #4 & #5 per M10

#7:       9/30/2020:  C445-1, separate from #2, #4 & #6 per M8, separate from #1, #3 & #5 per M10; I do not think the back, NOS (C445-9) is a new primary per M18.

#8:       10/18/2021:  C447-1, separate from #2, #4 & #6 per M8, separate from #1, #3, #5 & #7 per M10

Assign the number of primaries following the Other Sites Solid Tumor Rules.  Based on sites, laterality and or timing there are 8 primaries.  This is similar to SINQ 20061112 that advised to follow the Multiple Primaries/Histology rules for sebaceous carcinoma.  According to the WHO Classification of Skin Tumors, 5th edition, there is a 30-40% risk of local tumor recurrence, and 20-25% risk of distant metastasis.  In only one instance did a physician refer this as a recurrence in the available notes.

First Course Therapy/Neoadjuvant Treatment:  How are Neoadjuvant Therapy--Clinical Response and Neoadjuvant Therapy--Treatment Effect coded when the neoadjuvant therapy was not completed? Does the entire course of neoadjuvant therapy need to be completed before we can code these fields? See Discussion.

Example: The neoadjuvant therapy was started, the patient progressed, the treatment plan was altered, and a new course of systemic therapy was started; surgery was cancelled.

01/25/21 Bile duct brushing: Malignant cells present, adenocarcinoma

01/26/21 Surgical oncology consult: Currently unresectable; recommend neoadjuvant chemo

02/22/21-3/29/21 Neoadjuvant Gemzar & Abraxane, two cycles, discontinued due to disease progression

04/17/21 Surgical oncology re-eval: CT positive for disease progression, need to change Rx

04/26/21 Second change of treatment due to progression: Irinotecan, Oxaliplatin, and 5FU

07/16/21 Surgical oncology re-eval: Unresectable, advise 4-6 months of chemo followed by radiation

Assign code 3 (Progressive disease (PD)(per managing/treating physician statement) for Neoadjuvant Treatment--Clinical Response and code 7 (Neoadjuvant therapy completed and planned surgical resection not performed) for Neoadjuvant Treatment--Treatment Effect. These are the best choices under the circumstances. Use text fields to record the details.

Reportability:  What American College of Radiology Reporting and Data Systems (RADS) can be used to determine reportability?  See Discussion.

LI-RADS (liver), PI-RADS (prostate), and TI-RADS (thyroid) can be used to determine reportability. BI-RADS (breast) and Lung-RADS cannot be used to determine reportability. Can these systems below to determine reportability?

C-RADS (from CT colonography)

NI-RADS (head & neck)

O-RADS (ovarian-adnexal)

The following cancer cases are reportable unless there is information to the contrary.

–Liver cases with an LI-RADS category LR-4 or LR-5

–Prostate cases with a PI-RADS category 4 or 5

The following are not reportable without additional information.

–Breast cases designated BI-RADS 4, 4A, 4B, 4C or BI-RADS 5

–Lung cases designated Lung-RADS 4A," 4B, or 4X

–Liver cases based only on an LI-RADS category of LR-3

–Colon cases with only C-RADS information (C-RADS category C4 is not reportable by itself)

–Head and Neck cases with only NI-RADS information (NI-RADS category 3 is not reportable by itself)

–Ovarian or fallopian tube cases with only O-RADS information (none of the O-RADS categories are reportable without additional information)

–Thyroid cases with only TI-RADS information (none of the TI-RADS categories are reportable without additional information)

Update to Current Manual/Neoadjuvant Therapy--Pancreas:  How are the neoadjuvant items coded for a patient who has unresectable pancreatic cancer and starts chemotherapy but will be evaluated after X cycles to see if patient may become a surgical candidate?

Assign the neoadjuvant therapy data items as if the patient had neoadjuvant therapy.  Neoadjuvant Therapy data item would be coded either code 1 or 2 depending on whether the chemotherapy was completed or not. In this case, they are a surgical candidate by having the chemotherapy with the plan from the beginning to evaluate the chemotherapy after X cycles to see if surgery can be performed. After the patient is evaluated, update the abstract as needed.

Solid Tumor Rules (2018/2021)/Multiple Primaries--Corpus Uteri:  How many primaries should be reported when a hysterectomy identifies primary endometrial carcinosarcoma (8980/3) and the endometrium has a background of endometrioid intraepithelial neoplasia (EIN) (8380/2)? A tumor size is provided for the carcinosarcoma, but not the background EIN.

Patient was diagnosed with carcinosarcoma of Mullerian origin on omental/pelvic biopsies in March 2021. First course treatment was neoadjuvant chemotherapy followed by July 2021 resection showing residual primary endometrial carcinosarcoma with cervical stromal invasion and involvement of bilateral tubes/ovaries, omentum, and mesenteric nodule. Additional findings included endometrium with background endometroid intraepithelial neoplasia (EIN).

Abstract this case as a single primary and code histology as carcinosarcoma (8980/3). The carcinosarcoma is intermixed with the EIN making this a single primary coded to the invasive histology. EIN is a precursor of endometrial carcinoma in the WHO Classification of Female Genital Tumors, 5th edition. Carcinosarcoma of the uterus is described in the literature as an aggressive variant of endometrial carcinoma characterized by unusual histologic features including discrete malignant epithelial and mesenchymal components (carcinoma and sarcoma).

Solid Tumor Rules (2018/2021)/Histology--Breast:  How is histology coded for a diagnosis of invasive mammary neuroendocrine tumor (NET), grade 2/3? See Discussion.

Table 3 (Breast Equivalent Terms and Definitions) lists “Neuroendocrine tumor, well-differentiated” of the breast as histology 8246/3. There is no entry for a grade 2 neuroendocrine tumor of the breast in Table 3.  

The pathologist did not indicate the neuroendocrine tumor was poorly differentiated (or it would otherwise be considered a small cell carcinoma). The pathologist noted “By current WHO criteria, this tumor is characteristic of a mammary neuroendocrine tumor, grade 2.  These invasive tumors are considered to have similar prognostic and predictive features of invasive ductal carcinoma of the same grade and stage.”

Assign code 8249/3, neuroendocrine tumor, grade 2 based on the pathologist statement of mammary neuroendocrine tumor grade 2.  According to WHO Classification of Tumors of the Breast, 5th edition, neuroendocrine tumor (NET) is an invasive tumor characterized by low/intermediate grade.

If the histology term is not listed in the Solid Tumor rules, the instructions state to also check ICD-O and updates. Per ICD-O, NET, grade 2 is coded 8249/3. Breast Table 3 will be updated for 2023.
