NAACCR XML: Tumor.separateTumorNodules
Description
"Separate tumor nodules" refers to what is conceptually a single tumor with intrapulmonary metastasis in the ipsilateral (same) lung. Their presence in the same or different lobes of lung from the primary tumor affects the T and M categories.
Rationale
This data item was previously collected for Lung, SSF# 1 and at least one standard setter is continuing to collect it.
Codes
        0 No separate tumor nodules; single tumor only  
 Separate tumor nodules of same histologic type not identified/not present  
 Intrapulmonary metastasis not identified/not present  
 Multiple nodules described as multiple foci of adenocarcinoma in situ or minimally invasive adenocarcinoma  
        1 Separate tumor nodules of same histologic type in ipsilateral lung, same lobe  
        2 Separate tumor nodules of same histologic type in ipsilateral lung, different lobe  
        3 Separate tumor nodules of same histologic type in ipsilateral lung, same AND different lobes  
        4 Separate tumor nodules of same histologic type in ipsilateral lung, unknown if same or different lobe(s)  
        7 Multiple nodules or foci of tumor present, not classifiable based on notes 3 and 4  
        8 Not applicable: Information not collected for this case  
 (If this item is required by your standard setter, use of code 8 will result in an edit error.)  
        9 Not documented in medical record  
 Primary tumor is in situ  
 Separate Tumor Nodules not assessed or unknown if assessed  
Each Site-Specific Data Item (SSDI) applies only to selected primary sites, histologies, and years of diagnosis. Depending on applicability and standard-setter requirements, SSDIs may be left blank.
