Comments
Guide for use:
Record whether a person with cancer has multiple primary tumours, regardless of whether they are synchronous or metachronous.
Patients with multiple primary tumours may have a worse prognosis or more extensive treatment than patients with a single tumour. In addition, the management and prognosis when multiple primary tumours are present may vary depending on whether the tumours are synchronous or metachronous.
