CS Tumor Size/CS Site Specific Factor 6--Breast: How are these fields coded for a tumor stated to have only in situ disease in the breast with bone metastasis identified on scan? See Discussion.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Lung: How is histology coded for the tumor(s) that exist if a left upper lobe of lung resection final diagnosis states the patient has a moderately differentiated adenocarcinoma and the path indicates there are "multiple carcinoid tumorlets"?
Histology (Pre-2007)/Behavior Code/Sequence Number-Central -- Ovary: How are these fields coded for a "serous tumor of low malignant potential" when lymph nodes are discovered to be involved?
Sequence Number-central/Multiple Primaries (Pre-2007): What criteria are to be used to determine which primary site carries a worse prognosis? Should we take survival into consideration? See Discussion.
First Course Treatment: If a patient makes a blanket refusal of all recommended therapy or refuses all treatment before any therapy was recommended, are only immunotherapy and hematologic/endocrine therapies to be coded as refused (code 87)? Or should all treatment modalities be coded as refused if a patient makes a blanket refusal? Or should none of the treatment modalities be coded as refused because we do not know what would have been recommended? See Discussion.
Histology--Prostate: We are seeing numerous pathology reports with the following diagnosis: "Conventional (acinar) prostatic adenocarcinoma (M81403)." What is the correct histology code?
Reportability--Brain and CNS: Is a skull tumor schwannoma an intracranial reportable benign tumor if the physician states it arose in the occipital nerve?
