Guide for use:
Record all distant metastatic site(s) identified at the time of diagnosis of the cancer.
Site refers to the anatomical position of the distant metastatic disease.
Use the latest edition of the AJCC Cancer Staging Manual or UICC TNM Classification of Maligant Tumours to distinguish between regional involvement and distant metastatic sites. Cases with sites of distant metastasis would be coded M1.
Do not code sites of regional or local metastasis as defined in the "T" field.
Do not update this record with the sites of distant metastasis diagnosed subsequent to the initial diagnosis.Comments:
The presence of distant metastatic disease at diagnosis is an independent prognostic indicator and may influence treatment decisions.
