Solid Tumor Rules (2018)/Histology--Breast: How is the histology coded and which H Rule applies for a single tumor with final diagnosis of invasive mammary carcinoma and College of American Pathologists (CAP) synoptic report states, Histologic type: Invasive cribriform carcinoma with no mention of a tumor percentage? See Discussion.

Solid Tumor Rules/Multiple Primaries--Breast: How many primaries should be abstracted for simultaneously diagnosed non-contiguous invasive duct carcinoma and mucinous carcinoma? Does rule M12 apply since the two histologies are on different rows of Table 3 of the Breast Solid Tumor Rules? See Discussion.

First Course of Treatment/Hormone Therapy--Breast: Is hormone therapy (HT) prescribed for invasive ductal carcinoma of the right breast coded as treatment for lobular carcinoma in situ (LCIS) of the left breast even though the treatment plan for the LCIS was documented as surveillance? See Discussion.

Reportability/Histology--Vulva/Penis: Are differentiated penile intraepithelial neoplasia (C60._) and differentiated vulvar intraepithelial neoplasia (C51._) reportable for cases diagnosed 2018+? See Discussion.

Reportability/Histology--Penis: Is a diagnosis of undifferentiated penile intraepithelial neoplasia (PeIN) reportable for cases diagnosed in any year? See Discussion.

Update to current manual/Neoadjuvant therapy/Pathologic tumor size--Breast: When a patient with invasive breast cancer is started on neoadjuvant therapy and at surgery is found to have only residual in-situ disease, do we record the size of the in-situ tumor for Pathologic Tumor Size? See Discussion.

Summary Stage 2018--Lung: Are ground-glass lung nodules coded as distant for Summary Stage? See Discussion.

Primary site--Head & Neck: Are cases with positive cervical lymph nodes that are EBV positive (EBV+) coded to the nasopharynx, and cases with positive cervical lymph nodes that are p16 positive (p16+) coded to the oropharynx, when no primary site is identified? See Discussion.

Summary Stage 2018/Extension--Prostate: Can imaging be used to code SEER Summary Stage 2018? MRI shows tumor involved the seminal vesicles and the patient did not have surgery. AJCC does not use imaging to clinically TNM stage a prostate case.

Reportability--Testis: Is demarcated scar tissue with atrophic seminiferous tubules and cortical bone consistent with burnt-out germ cell tumor and no evidence of germ cell neoplasia in situ (GCNIS) reportable? See Discussion.
