Abstract
Some studies have shown reduced portal blood flow in patients with occult hepatic metastases, which may lead to decreased liver volume. A retrospective study was conducted in patients undergoing curative resection for colorectal (n = 63) or gastric (n = 52) cancer. The ratio of the preoperative computed tomography (CT)-estimated liver volume to the standard liver volume (CV/SV ratio) was calculated. The mean ± SD CT-estimated liver volume was 858 ±109 in 14 patients who subsequently developed hepatic metastases and 1173 ± 230 ml in 101 patients without metastases (p < 0.0001). The CV/SV ratio was smaller in patients with metachronous hepatic metastases than in those without (0.78 ± 0.08 vs. 1.02 + 0.13; p < 0.0001). The results suggest that the liver with occult metastases decreases in size before metastases develop that are detectable using conventional imaging techniques. The CV/SV ratio may be of value in detecting occult hepatic metastases from colorectal and gastric cancer.
