Based on pathologic findings, patients were divided into groups based on whether or not they had LC. Parameters associated with hepatic functional reserve were compared in these two groups using MannWhitney U-test for univariate analysis. Factors differing significantly in univariate analyses were entered into multivariate logistic regression analysis.RESULTS There were significant differences between the LC group(n = 100) and non-LC group(n = 202) in prothrombin activity, concentrations of alanine aminotransferase, aspartate aminotransferase, total bilirubin, albumin, cholinesterase, type Ⅳ collagen, hyaluronic acid, indocyanine green retention rate at 15 min, maximal removal rate of technitium-99 m diethylene triamine pentaacetic acid-galactosyl human serum albumin and ratio of mean platelet volume to platelet count(MPV/PLT). Multivariate analysis showed that prothrombin activity, concentrations of alanine aminotransferase, aspartate aminotransferase, total bilirubin and hyaluronic acid, and MPV/PLT ratio were factors independently predictive of LC. The area under the curve value for MPV/PLT was 0.78,with a 0.8 cutoff value having a sensitivity of 65% and a specificity of 78%.CONCLUSION The MPV/PLT ratio, which can be determined simply from the complete blood count, may be a simple surrogate marker predicting LC.展开更多

METHODS： A retrospective analysis of 198 consecutive patients with HCC who underwent partial hepatectomies in the past 14 years was conducted. The selection criteria for hepatectomy procedures during the study period were KICG≥0.12 for hemihepatectomy, KICG≥0.10 for bisegmentectomy, KCG≥0.08 for monosegmentectomy, and KICG≥ 0.06 for nonanatomic hepatectomy. The hepatectomies were categorized into three types： major hepatectomy （hemihepatectomy or a more extensive procedure）, bisegmentectomy, and limited hepatectomy. Univariate （Fishers exact test） and multivariate （the logistic regression model） analyses were used. RESULTS： Postoperative mortality was 5% after major hepatectomy, 3% after bisegmentectomy, and 3% after limited hepatectomy. The bhree percentages were comparable （P = 0.876）. The platelet count of ≤ 10× 10^4/μL was the strongest independent factor for postoperative mortality on univariate （P = 0.001） and multivariate （risk ratio, 12.5; P= 0.029） analyses. No patient with a platelet count of 〉7.3× 10^4/μL died of postoperative morbidity, whereas 25% （6/24 patients） of patients with a platelet count of ≤7.3×10^4/μL died （P〈0.001）. CONCLUSION： The selection criteria for hepatectomy procedures based on KICG are generally considered valid, because of the acceptable morbidity and mortality with these criteria. The preoperative platelet count independently affects morbidity and mortality after hepatectomy, suggesting that a combination of KICG and platelet count would further reduce postoperative mortality.展开更多
