Code EOD Primary Tumor using the post neoadjuvant information for this case. Since the only information you have is the post neoadjuvant, code that. EOD combines clinical and pathological information.

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

–Liver cases with an LI-RADS category LR-4 (reportable since 2021) or LR-5 (reportable since 2016)

–Prostate cases with a PI-RADS category 4 or 5 (reportable since 2017)

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)

Do not report superficial CD34-positive fibroblastic tumor (8810/1) of the thigh.

WHO Classification of Soft Tissue and Bone Tumors, 5th ed., defines superficial CD34-positive fibroblastic tumor as a distinctive low-grade neoplasm of the skin and subcutis, most frequently occurring in the lower extremities, especially thigh, followed by arm, buttock, shoulder, and rarely, vulva.

Self-reported information is the highest priority for coding race. That is because the race information for the U.S. population comes from census data and that information is self-reported. For national cancer statistics, in order for the numerator (cancer cases) and the denominator (population) to be comparable, use self-reported race information whenever it is available. We will add this clarification to the SEER manual.

Code myoepithelial carcinoma ex pleomorphic adenoma as carcinoma ex pleomorphic adenoma (CXPA) (8941/3) using Head and Neck Solid Tumor Rule H1 as this is a single histology.  The WHO Classification of Head and Neck Tumors, 5th ed., describes CXPA as a rare epithelial and/or myoepithelial malignance arising in association with a primary or recurrent pleomorphic adenoma.  The histologic type of the carcinoma component is usually recorded, in this case, myoepithelial carcinoma.

Do not report LR-TR viable as a new primary. LR-TR viable is a component of the Li-RADS Treatment Response algorithm designed to assess response for path-proven or presumed (e.g., LR-4, LR-5, LR-M) malignancy after locoregional treatment for hepatocellular cancer. LR-TR viable indicates it met the criteria as a viable tumor.

For cases diagnosed 2007 or later:

Use the 2007 MP/H rules for urinary sites to assess diagnoses made in 2007-2014. Use the multiple tumors module to compare a diagnosis in 2007-2014 to an earlier diagnosis.

For the example above, start by comparing the left renal pelvis diagnosis in 8/07 to the earlier left ureter primary diagnosed 5/05. Start with rule M3. Stop at rule M8. The 8/07 renal pelvis diagnosis is not a new primary. Next, compare the 3/08 bladder tumor to the earlier left ureter primary diagnosed 5/05. Start with rule M3. Stop at rule M5. The 3/08 bladder tumor is a new primary because it is an invasive diagnosis following an in situ diagnosis. Use only the more recent of the two earlier urinary diagnoses for comparison. Do not compare the 2007 and later diagnoses to the 11/89 in situ bladder primary in this case.

According to our subject matter expert, vulvar extramammary Paget neoplasm (intraepithelial glandular neoplasm) represents an in situ malignancy and should be reported.

He states "The traditional terminology should be 'extramammary Paget disease' to describe an in situ adenocarcinoma arising from extramammary glands in vulvar mucosa. I am not so sure about "extramammary Paget NEOPLASM", which may include all three Pagetoid processes: the traditional Paget disease, the Pagetoid spreading of an anal adenocarcinoma and a Pagetoid spreading of an urothelial carcinoma from the urethra. Regardless, all these entities are considered at least in situ carcinomas."

We recommend that you review clinical records and imaging for the clinical scenarios mentioned above.

For cancer registry data collection, follow the instructions in SEER*Rx. It is important for all data collection to be consistent for reporting of cancer information.

Per the FDA: Ibrance is a chemotheraputic agent which was approved for use WITH Letrozole. Letrozole is a hormonal drug which may be why the physicians are stating the patient is receiving hormones. Ibrance should not be given alone to treat breast cancer. This drug will not be changing categories in SEER*Rx.
