For a primary endometrial or ovarian cancer, record the oophorectomy/BSO procedure using the appropriate Surgery of Primary Site code that includes oophorectomy/BSO when done as part of first course of treatment (surgical resection). If performed for hormone effect, also record in the Hematologic Transplant and Endocrine Procedures data item.  For other primary sites whose Surgery of Primary Site codes do not include oophorectomy/BSO, record it in the Hematologic Transplant and Endocrine Procedures data item when performed for hormone effect.  Document information in the appropriate text fields.

Candidates for risk-reducing BSO may include those with hereditary syndromes (such as BRCA mutations) or genes that carry a substantially increased lifetime risk of ovarian malignancy or hormone-sensitive cancers including estrogen-dependent cancers, like breast cancer, ovarian cancer and endometrial (uterine) cancer that rely on estrogen to develop and grow.

A change in the subcategory for a hormone drug does not indicate the end of First Course of Treatment because different hormone therapies generally achieve the same result. For example, some forms of breast cancer are estrogen-dependent and the various subcategories of hormone drugs used to treat them, such as gonadotropin-releasing factor agonists, aromatase inhibitors and estrogen antagonists, all achieve the same result - to block estradiol effects in these tumors.

Similarly, a change in immunotherapy is not a new course of treatment.

The instruction in the SEER Manual is specific to chemotherapy. Chemotherapy is the only systemic treatment for which a change in the subcategory of a drug indicates the end of First Course of Treatment, due to the fact that different chemical agents damage cancer cells in different ways and at different phases in the cell cycle.

Use the patient's usual residence to determine residency. If the usual residence is not known or the information is not available, use the residence the patient specifies at the time of diagnosis. The SEER rules for determining "usual residence" match the rules used by the US Census Bureau.

According to the editors of ICD-O-3, lobular neoplasia grade 2 is not equivalent to LCIS. It is not a reportable term. Lobular neoplasia and lobular intraepithelial neoplasia are equivalent terms having a three grade system. Only LN/LIN grade 3 would be reportable since those terms are analogous to ductal intraepithelial neoplasia grade 3.

According to the WHO classification of breast tumors, "lobular neoplasia (LN) refers to the entire spectrum of atypical epithelial lesions originating in the terminal-duct lobular unit…" Report the case when lobular carcinoma in situ (LCIS) is stated. When LN or lobular intraepithelial neoplasia (LIN) are described using the three-grade system, report LN/LIN grade 3. Only LN/LIN grade 3 is reportable since those terms are analogous to ductal intraepithelial neoplasia grade 3 (See Intraepithelial neoplasia 3, ductal in ICD-O-3). WHO Classifications of Tumors are the preferred references for questions like this.

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)

Typically, the final diagnosis of the reviewing pathologist is the one used to determine whether the case is SEER reportable. If two or more reviewing pathologists disagree as to whether the case should be reportable, determine reportability based on the following priority order:

1) If the patient is treated for cancer, the case is reportable.

2) If the patient is not treated for cancer, use the amended diagnosis on the original pathology report if the hospital pathologist used the reviewing pathologists' opinions in establishing his new diagnosis.

3) If there is not an amended diagnosis for the original hospital pathology report, use the clinician's opinion regarding what the diagnosis is to determine whether the case is reportable.

This neoplasm is reportable because it is malignant as proven by the lymph node metastases. Code the behavior as malignant (/3) when there are lymph node metastases.

For cases diagnosed 2018 and later

Differentiated penile intraepithelial neoplasia (differentiated PeIN), is reportable (8071/2).

Please note: Penile intraepithelial neoplasia, grade 3 (PeIN 3) is also reportable to SEER (C600-C609, 8077/2).

Accession the case and code Diagnostic Confirmation as 8 [clinical diagnosis only]. Accession a case with negative pathology when the clinician is aware of the negative pathology and continues to refer to the case as malignant.
