Description
This field identifies whether lung is an involved metastatic site. The six Mets at Dx-Metastatic Sites fields provide information on specific metastatic sites for data analysis.
Rationale
Information on site of metastatic disease at diagnosis has prognostic implications to survival among patients with initial late stage disease. Capturing data on where the patient’s metastatic lesions (including the number of locations) will be an important variable to include when looking at survival. Survival among metastatic patients is becoming increasingly important for cancer survivors.
Codes
0 None; no lung metastases
1 Yes; distant lung metastases
8 Not applicable
9 Unknown whether lung is involved metastatic site. Not documented in patient record.
