title: [Prognosis of hepatic metastasis from colorectal cancer following arterial infusion chemotherapy--assessment from the percentage of tumor involved area and tumor markers].
abstract: Prognosis of hepatic metastasis from colorectal cancer following arterial infusion chemotherapy was studied from the percentage of tumor involved area (PTIA) and tumor markers. The PTIA was calculated by the following formula: sigma S'/ sigma S, with S' as the tumor area and S as the liver area on each CT slice. The PTIA was 0.76 to 31.1%, and the average was 6.84%. As for the correlation between the PTIA and the prognosis, a statistically significant reverse correlation was found in the cases of death (r = -0.455, p < 0.05, n = 22). In the tumor regression effect of NC cases, the 50% survival time was 24.4 months in cases showing a decrease in CEA or CA19-9 and 18.7 months in the cases showing an increase. Prognosis of the former cases was significantly better than that of the latter cases (p < 0.05). Therefore, PTIA and the decrease in CEA or CA19-9 in the cases of hepatic arterial infusion chemotherapy for metastasis from colorectal cancer seemed important factors reflecting prognosis.
