MP/H Rules--Bladder: Is a TURBT in 4/07 that demonstrates papillary carcinoma (8130/3) followed two weeks later with biopsies that demonstrate high grade flat dysplasia/carcinoma in situ (8010/2) two primaries?
MP/H Rules--Breast: How many primaries should be abstracted when a patient has a mass at 6:00 that showed poorly differentiated ductal carcinoma and a hypoechoic nodule at 9:00 that was excised with no real tumor present there though path showed angiolymphatic invasion by carcinoma throughout the entire specimen? See Discussion.
MP/H Rules/Date of Diagnosis/Behavior--Brain and CNS: How many primaries would be reported when a December 2004 MRI shows a pineal region mass with the major differential consideration being pineocytoma; a November 2007 MRI that shows the mass has almost tripled in size; and the December 2007 resection final diagnosis is consistent with pineoblastoma? How would diagnosis date[s] and behavior code[s] be coded? See Discussion.
CS Tumor Size--Lung: If a 5/11/07 CT showed a 6.5 cm LLL mass and a 7/24/07 CT showed 8.4 cm LLL mass, do we code the larger tumor size identified within four months of diagnosis or do we code the first size documented at the time of diagnosis?
Reportability/Histology--Head and Neck: Is a right cerebellopontine (CP) angle endolymphatic sac papillary tumor (ELST) reportable? If so, what is the histology code?
CS Extension--Lung: Chest CT shows segmental atelectasis (CS EXT code 40), but patient had Left Lower Lobe lobectomy/Lymph Node dissection with no involvment outside the lobe (pleura and all margins neg). Do we still code the atelectasis (CS Ext 40) over confined to lung (CS EXT code 10)?
MP/H Rules--Lung: In reference to lung, SINQ 20071028 states "'nodule' is not an equivalent term for tumor, mass, lesion, or neoplasm." However, slide 5 for the MPH lung section of "Beyond the Basics" states "we use the words 'mass, nodule and lesion' interchangeably." Which is it?
