This study estimated the predictability of preoperative tumor marker levels along with pathological parameters on HCC recurrence after hepatectomy.METHODS： A total of 140 patients with HCC who underwent hepatectomy between January 2012 and August 2012 were enrolled. The demographics, clinical and follow-up data were collected and analyzed. The patients were divided into two groups： patients with macroscopic vascular invasion（Ma VI ＋） and those without Ma VI（Ma VI-）. The predictive value of tumor markers and clinical parameters were evaluated by univariate and multivariate analysis.RESULTS： In all patients, tumor size（〉8 cm） and Ma VI were closely related to HCC recurrence after hepatectomy. For Ma VI＋ patients, VEGF（〉900 pg/m L） was a significant predictor for recurrence（RR=2.421; 95% CI： 1.272-4.606; P=0.007）. The 1- and 2-year tumor-free survival rates for Ma VI＋ patients with VEGF ≤900 pg/m L versus for those with VEGF 〉900 pg/m L were 51.5% and 17.6% versus 19.0% and 4.8%（P〈0.001）. For Ma VI- patients, DCP 〉445 m Au/m L and tumor size 〉8 cm were two independent risk factors for tumor recurrence（RR=2.307, 95% CI： 1.132-4.703, P=0.021; RR=3.150, 95% CI： 1.392-7.127, P=0.006; respectively）. The 1- and 2-year tumor-free survival rates for the patients with DCP ≤445 m Au/m L and those with DCP 〉445 m Au/m L were 90.4% and 70.7% versus 73.2% and 50.5% respectively（P=0.048）. The 1-and 2-year tumor-free survival rates for the patients with tumor size ≤8 cm and 〉8 cm were 83.2% and 62.1% versus 50.0% and 30.0%, respectively（P=0.003）.CONCLUSIONS： The Ma VI＋ patients with VEGF ≤900 pg/m L had a relatively high tumor-free survival than those with VEGF 〉900 pg/m L. In the Ma VI- patients, DCP 〉445 m Au/m L and tumor size 〉8 cm were predictive factors for postoperative recurrence.展开更多

High quality clinical trial has been conducted in liver transplant(LT) recipients in Western countries. However, the pertinent studies in Eastern world are paucity. Therefore, we designed a clinical trial to test whether sirolimus can improve recurrence-free survival(RFS) in hepatocellular carcinoma(HCC) patients beyond the Milan criteria after LT. This is an open-labeled, single-arm, prospective, multicenter, and real-world study aiming to evaluate the clinical outcomes of early switch to sirolimus-based regimens in HCC patients after LT. Patients with a histologically proven HCC and beyond the Milan criteria will be enrolled. The initial immunosuppressant regimens are center-specifc for the frst 4-6 weeks. The following regimens integrated sirolimus into the regimens as a combination therapy with reduced calcineurin inhibitors based on the condition of patients and centers. The study is planned for 4 years in total with a 2-year enrollment period and a 2-year follow-up. We predict that sirolimus conversion regimen will provide survival benefts for patients particular in the key indicator RFS as well as better quality of life. If the trial is conducted successfully, we will have a continued monitoring over a longer follow-up time to estimate indicator of overall survival. We hope that the outcome will provide better evidence for clinical decision-making and revising treatment guidelines based on Chinese population data.展开更多
