CS Extension/CS Mets at Dx--Peritoneum: How are these fields coded for extraovarian peritoneal carcinomas presenting with multiple peritoneal implants? See Discussion.
CS Lymph Nodes/CS Mets at Dx--Melanoma: How are these fields coded for a melanoma primary when melanoma is identified in lymph nodes but no primary skin tumor is found? See Discussion.
CS Site Specific Factor--Head & Neck: If a lymph node dissection of the neck reveals that 1/24 lymph nodes is positive and the positive 5.6 cm lymph node extends throughout levels II-IV, how are the SSF 3 (status of levels I-III lymph nodes) and SSF4 (status of levels IV-V lymph nodes) fields coded?
CS Site Specific Factor--Prostate: How is SSF 6 coded for this site when there is only one Gleason number documented and the number is less than 5 (e.g., Gleasons 3)?
Reportability--Anus: Is a final diagnosis on a pathology report of "squamous cell carcinoma of the anus, NOS" assumed to be a skin of anus primary or a primary of the anus?
CS Tumor Size/CS Site Specific Factor--Breast: Should the tumor size be coded to 1.5 cm or 2.5 cm and SSF6 coded to 020 or 030 respectively for a tumor with invasive and in situ components described as being a 2.5 cm tumor with a "greater than" 1.5 cm invasive portion? See Discussion.
Multiple Primaries/Histology--Lymphoma: If a gastric biopsy demonstrates large B cell lymphoma arising in a low grade MALT lymphoma, how many tumors should be abstracted and how should the histology field(s) be coded? See Discussion.
