Abstract

AIMS:

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.

METHODS:

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.

RESULTS:

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.

CONCLUSION:

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.
