Behavior--Breast: Should the behavior change to /3, invasive, to get a case to clear edits? The histology of this breast case is ductal carcinoma in situ (DCIS), 8500/2. Lymph nodes are positive for micro-mets (0.2 mm-2 mm). SEER Summary Stage: 3, regional lymph nodes positive. This creates an edit for SEER Summary Stage due to the behavior code of /2, in situ.
Behavior--Breast: What is the behavior of a solid papillary carcinoma when a pathologist does not indicate it in the pathology report and follow-up with the pathologist to obtain clarification regarding the behavior is not possible? See Discussion.
Behavior--Prostate: What is the correct behavior of intraductal carcinoma from a prostate biopsy with a Gleason score 4+4=8. While highly aggressive, but not suggestive of invasion, coding behavior as /2 seems inappropriate.
Behavior/Date of Diagnosis--Lung: If the term "Pancoast tumor, NOS" is malignant by definition, should the date of diagnosis be coded to the date of the clinical diagnosis when the clinical diagnosis is made prior to the histologic confirmation of the malignancy?
Behavior/Summary Stage 2018--Colon: What is the correct behavior and Summary Stage for a case of intramucosal adenocarcinoma arising in tubular adenoma? AJCC states this is Tis, though SEER Summary Stagie states this is Localized (code 1). The histology is 8140/2 (adenocarcinoma in situ), but the SEER Summary Stage is Locallized.
Birthplace/Place of birth, country: For patients originally born in a country that is currently listed as "historic only", where the original birth country now has a one-to-many relationship with the current country, how should the reported original birthplace be coded? (Example: Yugoslavia)
CS Extension--Brain and CNS: How is CS Extension coded for a malignant meningioma that demonstrates extension into adjacent brain tissue?
For malignant brain tumors, code 60 represents extension into the meninges. Would code 60 be the correct code for extension from a malignant meningioma into brain tissue?
