CEA-doubling time (CEA-dt) was calculated by measuring serum CEA at two voluntary points. As CEA-dt is correlated with tumour doubling time the growth rate of liver metastasis could be determined. We investigated the relationship between CEA-dt and prognosis to determine the indications for resection of liver metastasis.


We examined 334 patients diagnosed with resected liver metastasis of colorectal carcinoma. Patients were divided into three categories based on CEA-dt; Group A, CEA-dt <30 days; Group B, 30 days </=cCEA-dt <80 days; and Group C, CEA-dt >/=s80 days. Clinicopathological parameters, the 3-year or 5-year survival rate and the rate of recurrence were compared among the three groups.


In Group A, the survival time after hepatic resection was significantly shorter compared to the other groups. Furthermore, multiple liver metastasis showed slightly reduced CEA-dt levels compared with solitary metastasis, but even in patients with solitary liver metastasis, the rate of survival was poor. In 70% of Group A patients, recurrent tumour was recognized within 1 year of hepatic resection.


When surgery for liver metastasis of colorectal cancer is considered. Group A patients should be recognized as having a poor prognosis and a high rate of recurrence after hepatic resection, and CEA-dt should be employed as a prognostic factor.
