摘要
Background: Lower mean platelet volume(MPV) is an indicator of platelet activity in the setting of tumor development. This study was to assess the relationship between preoperative MPV and survival outcomes of patients with hepatocellular carcinoma(HCC) following liver transplantation(LT). Methods: The demographic and clinical characteristics of 304 HCC patients following LT were retrieved from an LT database. All the patients were divided into the normal and lower MPV groups according to the median MPV. The factors were first analyzed using a Kaplan–Meier survival analysis, then the factors with P < 0.10 were selected for multivariate Cox regression analysis and were used to define the independent risk factors for poor prognosis. Results: The 1-, 3-, and 5-year tumor free survival was 95.34%, 74.67% and 69.29% in the normal MPV group, respectively, and 95.40%, 59.97% and 42.94% in the lower MPV group, respectively( P < 0.01). No significant difference was observed in post-LT complications between the normal and lower MPV groups. Portal vein tumor thrombosis(PVTT)[hazard ratio(HR = 2.24;95% confidence interval: 1.46–3.43;P < 0.01) and lower MPV(HR = 1.58;95% confidence interval: 1.05–2.36;P = 0.03) were identified as independent prognostic risk factors for recipient survival. Conclusion: Preoperative lower MPV is a risk indicator of HCC patients survival outcomes after LT.
