SEER*RSA/Required data items--Melanoma: The site-specific data item, Ulceration, states it is required by "All" in SEER*RSA but in the NAACCR Data Dictionary table it states is it required by SEER, Commission on Cancer (CoC), and Canadian Cancer Registry (CCCR), not the National Program of Cancer Registries (NPCR). Does the definition of "All" in SEER*RSA not include NPCR? Also, please explain the difference between Required by: "All" and "Required by CCCR/Canada, COC, NPCR, SEER" (all listed out).

Scope of Regional Lymph Node Surgery--Lung: How do you code Regional Nodes Positive, Regional Nodes Examined, and Scope of Regional Lymph Node Surgery when a fine needle aspirate (FNA) or biopsy of supraclavicular lymph nodes is positive for a lung cancer primary? Supraclavicular lymph nodes are distant in SEER Summary Stage and regional by AJCC. See Discussion.

Seq no-central--Brain and CNS: How should subsequent tumors be sequenced when the patient has a history of a brain tumor, with no information on the behavior of the brain tumor? According to the sequencing rules, it appears some assumption must be made regarding the behavior of the brain tumor.

Sequence Number Central--Brain and CNS: How is Sequence Number--Central coded for current/recent benign brain/CNS tumors when the patient has a history of an additional non-malignant CNS tumor diagnosed prior to 2004 (when these tumors became reportable to SEER)? See Discussion.

Sequence Number--Central/Reportability--Heme & Lymphoid Neoplasms: Is a hematolymphoid disease included in the sequencing if it was not reportable at the time of diagnosis?

Sex: How should the sex field be coded for the newly allowable non-binary gender designation ? See Discussion.

Size of tumor--Breast: Please clarify guideline #7 if the only size you have is from a CORE biopsy specimen and imaging only states nonspecific sizes, like "architectural distortion" or "calcifications" and a core biopsy pathology reports invasive tumor spans 5mm. Do you use the core biopsy size, or use 999 for clinical tumor size? See discussion.

Solid Tumor Rules/Multiple Primaries--Testis: How many primaries and what M Rule applies when metastatic seminoma is diagnosed greater than 40 years after a left testicular teratoma with yolk sac tumor and embryonal carcinoma? See Discussion.

Solid Tumor Rules (2007/2021)/Multiple Primaries--Anus: Have the disease free interval criteria been met for the following case scenario. A patient was diagnosed with anal intraepithelial neoplasia (AIN) III in 7/2018 that was treated with local tumor destruction, followed by Pap smears and biopsies that prove AIN I or AIN II through 2020, before being diagnosed with a reportable AIN II or AIN III in 2021. See Discussion.

Solid Tumor Rules (2018)--Breast: How many primaries are accessioned when a prophylactic mastectomy reveals a final diagnosis of invasive tubular carcinoma, but the College of American Pathologists (CAP) Protocol includes ductal carcinoma in situ (DCIS) sized separately and it is not clear if these are different tumors? See Discussion.
