RESUMO

BACKGROUND: There is limited evidence concerning the postoperative platelet to lymphocyte ratio change (ΔPLR) in relation to the prognosis of hepatocellular carcinoma (HCC). This study was designed to evaluate the prognostic value of ΔPLR in patients with hepatitis B virus (HBV)-related small HCC who underwent liver resection. MATERIALS AND METHODS: We retrospectively reviewed 219 patients with HBV-related small HCC who underwent liver resection between February 2007 and April 2013. The patients were divided into two groups as follows: group A (ΔPLR ≥2.875, n = 94) and group B (ΔPLR <2.875, n = 125), according to receiver operating characteristic analysis. Demographic, clinical, and follow-up data were analyzed, and multivariate analysis was used to identify prognostic factors. RESULTS: The 1-, 3-, and 5-y overall survival (OS) rates were 90.5%, 72.3%, and 42.1%, respectively, in group A and 98.1%, 89.5%, and 86.4%, respectively, in group B (P < 0.001). Correspondingly, the 1-, 3-, and 5-y recurrence-free survival (RFS) rates were 57.5%, 36.1%, and 22.8%, respectively, in group A and 84.3%, 62.4%, and 55.4%, respectively, in group B (P < 0.001). Multivariate analysis showed that ΔPLR was an independent prognostic factor for both OS (P < 0.001, hazard ratio = 5.452, 95% confidence interval 2.592-11.467) and RFS (P < 0.001, hazard ratio = 2.191, 95% confidence interval 1.4611-3.288). CONCLUSIONS: ΔPLR was an independent prognostic factor for OS and RFS in patients with HBV-related small HCC who underwent liver resection.

RESUMO

BACKGROUND/AIMS: Low portal velocity (PV) was found in cirrhotic patients, which was thought to be a risk factor for post-hepatectomy liver failure (PHLF). This study attempted to find out whether a correlation existed between portal hemodynamics and PHLF. METHODOLOGY: From December 2010 to December 2012, all consecutive patients with Child-Pugh class A underwent liver resection were included. PV and PF were measured by using Doppler ultrasound preoperatively and on postoperative day 3. Portal hemodynamics change was explored. Univariable and multivariable analysis were used to identify risk factors for PHLF. RESULTS: PHLF occurred in 25 of 151 patients, and persistent PHLF in 9 patients. Mean portal velocity change (PVmeanC) was significantly different between patients with PHLF and patients without PHLF, but it failed to be identified as independent predictor for PHLF in multivariate analysis, which found alanine aminotransferase (ALT) and Ishak score significantly associated with PHLF, and only ALT significantly associated with persistent PHLF. Subgroup analysis of the 73 cirrhotic patients also showed that none of the portal hemodynamic parameters were independent risk factors for PHLF or persistent PHLF. CONCLUSIONS: None of the portal hemodynamic parameters could be used to predict PHLF or persistent PHLF.

RESUMO

BACKGROUND: Bisphosphonates have exhibited anti-tumor activity in non-small cell lung cancer (NSCLC). We aimed to evaluate whether the combination of bisphosphonates with tyrosine kinase inhibitors of EGFR (EGFR-TKIs) could obtain a synergistic effect on advanced NSCLC patients with EGFR mutations. METHODS: Between January 2008 and October 2013, 114 advanced EGFR mutations NSCLC patients who received EGFR-TKIs as first-line therapy were recruited from two cancer centers. Patients were separated into EGFR-TKIs alone or EGFR-TKIs plus bisphosphonates (combination) group. Median progression free survival (mPFS), median overall survival (mOS) distributions and survival curves were analyzed. RESULTS: Among the 114 patients, 62 had bone metastases (19 patients treated with EGFR-TKIs, 43 patients treated with EGFR-TKIs + bisphosphonates). Median PFS and OS were significantly improved in combination group compared with EGFR-TKIs group (mPFS: 15.0 vs 7.3 months, P = 0.0017; mOS: 25.2 vs 10.4 months, P = 0.0015) in patients with bone metastases. Among the 71 patients (19 patients with bone metastases) treated with EGFR-TKIs alone, patients with bone metastases had poor survival prognosis (mPFS:7.3 vs 12.1 months, P = 0.0434; mOS:10.4 vs 22.0 months, P = 0.0036). The survival of patients with bone metastases who received EGFR-TKIs plus bisphosphonates therapy was non-inferior to patients without bone metastases treated with EGFR-TKIs alone (mPFS: 15.0 vs 12.1 months, p = 0.1871; mOS: 25.2 vs 22.0 months, p = 0.9798). CONCLUSIONS: Concomitant use of bisphosphonates and EGFR-TKIs improves therapeutic efficacy and brings survival benefits to NSCLC patients with EGFR mutation and bone metastases.

RESUMO

MicroRNAs (miRNAs) play important roles in cancer progression by altering transcriptional control. The purpose of this study is to identify and explore specific miRNAs as prognostic and predictive biomarkers for bile duct cancer (BDC) by analyzing Next-generation data. miRNA expression profiles and corresponding clinical information of BDC samples were extracted from The Cancer Genome Atlas (TCGA). The differentially expressed miRNAs were determined by SAMR package in R software. Target genes of those miRNAs were predicted by Targetscan. Functional enrichment analysis and hypergeometric test analysis of target genes were performed. Then, diagnosis accuracy of miRNAs was judged by ROC Curves analysis. Total 120 differentially expressed miRNAs were obtained, of which six important miRNAs were selected and predicted as prognosis and predicting biomarkers in BDC. Besides, functional analysis showed that both enriched pathways were significantly related with ion binding, which might involve in the carcinogenesis of BDC. Moreover, top 3 important pathways sharing the most influence were noted. Our results demonstrated that hsa-miR-483-5p, hsa-miR-675, hsa-miR-139-3p, hsa-miR-598, hsa-miR-625 and hsa-miR-187 could serve as prognostic and predictive markers for survival of BDC patients and could potentially be provided as targets for future therapy.

RESUMO

BACKGROUND: Clinically significant portal hypertension (PHT) is considered as a contraindication for hepatectomy according to the guidelines of the European Association for Study of Liver and the American Association for Study of Liver Diseases. However, this issue remains controversial. Here we performed a meta- analysis to evaluate the impact of PHT on the results of hepatectomy for hepatocellular carcinoma (HCC). METHODS: Cohort studies evaluating the impact of clinically significant PHT, defined as oesophageal varices and/ or splenomegaly associated with thrombocytopenia, on the results of hepatectomy for HCC were identified using a predefined search strategy. Summary risk ratios (RRs) and 95% confidence intervals (95% CIs) for PHT and outcomes after hepatectomy for HCC were calculated. RESULTS: Seven cohort studies which including 574 cases with PHT and 1,354 cases without PHT were considered eligible for inclusion. The meta-analysis showed that, in all patients, pooled RRs of post-operative liver failure, post-operative ascites, peri-operative blood transfusion, operative mortality, 3- and 5-year overall survival associated with PHT were 2.23 (95% CI: 1.48-3.34, P=0.0001), 1.77 (95% CI: 1.19-2.64, P=0.005), 1.23 (95% CI: 1.03-1.49, P=0.03), 2.58 (95% CI: 1.12-5.96, P=0.03), 0.82 (95% CI: 0.75-0.88, P<0.00001) and 0.76 (95% CI: 0.69-0.85, P<0.00001), respectively. In subgroup analysis, similar results were found in Child-Pugh class A patients. CONCLUSION: This meta-analysis suggests that presence of oesophageal varices and/or splenomegaly associated with thrombocytopenia is associated with higher rates of post-operative complications and poor long-term survival after hepatectomy for HCC.

RESUMO

OBJECTIVE: This study aims to analyze the outcomes of patients with Child-Pugh A class cirrhosis and a single hepatocellular carcinoma (HCC) up to 5 cm in diameter who underwent liver transplantation vs. resection. METHODS: During 2007 to 2012, 282 Child-Pugh A cirrhotic patients with a single HCC up to 5 cm in diameter either underwent liver resection (N = 243) or received liver transplantation (N = 39) at our center. Patient and tumor characteristics and outcomes were analyzed. RESULTS: Patients who underwent liver transplantation had a better recurrence-free survival (RFS) vs. those who underwent liver resection. However, the 5-year survival rates after these two treatments were comparable. Similar results were observed when we analyzed patients with a HCC less than 3 cm, and for patients with portal hypertension. In the multivariate analysis, tumor differentiation, difference of primary treatment, and presence of microvascular invasion were associated with postoperative recurrence. However, only differentiation negatively impacted overall survival after operation. CONCLUSION: Although more recurrences were observed in Child A cirrhotic patients with a single HCC up to 5 cm after liver resection, liver resection offers a similar 5-year survival to liver transplantation, even for patients with portal hypertension.

RESUMO

BACKGROUND: The prognosis of patients with hepatocellular carcinoma (HCC) after curative resection varies greatly. Few studies had investigated the risk factors for early recurrence (recurrence-free time ≤ 1 year) of hepatitis B virus (HBV)-related HCCs meeting Milan criteria. METHODS: A retrospective analysis was performed on the 224 patients with HCC meeting Milan criteria who underwent curative liver resection in our center between February 2007 and March 2012. The overall survival (OS) rate, recurrence-free survival (RFS) rate and risk factors for early recurrence were analyzed. RESULTS: After a median follow-up of 33.3 months, HCC reoccurred in 105 of 224 patients and 32 died during the period. The 1-, 3- and 5-year OS rates were 97.3%, 81.6% and 75.6% respectively, and the 1-, 3- and 5-year RFS rates were 73.2%, 53.7% and 41.6%. Cox regression showed alpha-fetoprotein (AFP) > 800 ng/ml (HR 2.538, 95% CI 1.464-4.401, P=0.001), multiple tumors (HR 2.286, 95% CI 1.123-4.246, P=0.009) and microvascular invasion (HR 2.518, 95% CI 1.475-4.298, P=0.001) to be associated with early recurrence (recurrence-free time ≤ 1-year) of HCC meeting Milan criteria. CONCLUSIONS: AFP > 800 ng/ml, multiple tumors and microvascular invasion are independent risk factors affecting early postoperative recurrence of HCC. In addition resection appears capable of replacing liver transplantation in some situations with safety and a better outcome.
