SD = standard deviation.

1 Patients with only 1 scan are not included in these calculations.

2 A significant difference (unpaired Student t test, P < 0.05) was found when the time to metastasis from the colon to the lung or bone was compared with the time to metastasis from the colon to the liver.

3 No significant difference (P > 0.05) was found when the time from lung metastasis to bone metastasis was compared with the time from liver metastasis to bone metastasis.
