Background/Aims:
Technetium-99m galactosyl human serum albumin is a novel liver scintigraphic agent. The aim of the present study was to examine whether liver scintigraphy with this agent could predict changes in hepatic function affecting survival in patients with inoperable hepatocellular carcinoma and liver cirrhosis. We also investigated whether the risk of major complications after hepatectomy for hepatocellular carcinoma could be assessed.
Methodology:
Liver scintigraphy was performed in 42 patients with inoperable hepatocellular carcinoma and cirrhosis and 40 patients undergoing hepatectomy. The ratio of liver to heart plus liver radioactivity 15 min after injection (LHL15) was calculated.
Results:
The 1-year survival rates were higher in patients with higher LHL15: 100%, LHL15 > or = 0.91; 77.8%, 0.81 < or = LHL15 < or = 0.90; and 28.6%, LHL15 < or = 0.80. On multifactorial analysis, LHL15 significantly predicted the 1-year mortality rate in the 42 patients (p<0.001). Pre-operative LHL15 was significantly lower in 9 patients with major post-operative complications (0.88+/-0.02) than in 31 patients with uneventful courses or minor post-operative complications (0.93+/-0.01, p<0.001).
Conclusions:
Our results suggest that technetium-99m galactosyl human serum albumin liver scintigraphy is effective for predicting short-term survival in patients with inoperable HCC and cirrhosis and for assessing the risk of major complications after hepatectomy.
