Project description:BackgroundHepatic resection is the preferred treatment for huge hepatocellular carcinoma (>10 cm in diameter; H-HCC). However, the patients with H-HCC suffer from poor prognosis due to the early recurrence/metastasis. The underlying mechanism of H-HCC's early recurrence/metastasis is currently not well understood.ResultsHere, we describe an Isobaric Tags for relative and absolute quantification (iTRAQ)-based quantitative proteomics approach to analyze the early recurrence/metastasis related proteins of H-HCC after radical resection through multidimensional chromatography coupled with tandem mass spectrometry (2DLC-MS/MS). The different protein expression profiles between the early recurrence/metastasis within 6 months(R/M≤6months) and late recurrence/metastasis within 6-12 months after surgery (R/M6-12months) were confirmed and might reveal different underlying molecular mechanisms. We identified 44 and 49 significantly differentially expressed proteins in the R/M≤6months group and the R/M6-12months group compared to the group who had no recurrence within 2 years post surgery (the NR/M group), respectively. Moreover, among those proteins, S100A12 and AMACR were down regulated in the R/M≤6months group but up-regulated in the R/M6-12months group; and this regulation was further confirmed in mRNA and protein level by Q-PCR, Western-Blot and Immunohistochemistry (IHC).ConclusionsThis current study presents the first proteomic profile of the early recurrence/metastasis of H-HCC. The results suggest that S100A12 and AMACR might be potential prognostic markers for predicting the early recurrence/metastasis of H-HCC after hepatectomy.

Project description:The reliable prediction of hepatocellular carcinoma (HCC) recurrence patterns potentially allows for the prioritization of patients for liver resection (LR) or transplantation.The aim of this study was to analyse clinicopathological factors and preoperative Milan criteria (MC) status in predicting patterns of HCC recurrence.During 1992-2012, 320 patients undergoing LR for HCC were categorized preoperatively as being within or beyond the MC, as were recurrences.After a median follow-up of 47 months, 183 patients developed recurrence, giving a 5-year cumulative incidence of recurrence of 62.5%. Patients with preoperative disease within the MC had better survival outcomes than those with preoperative disease beyond the MC (median survival: 102 months versus 45 months; P < 0.001). Overall, 31% of patients had preoperative disease within the MC and 69% had preoperative disease beyond the MC. Estimated rates of recurrence-free survival at 5 years were 61.8% for all patients and 53.8% for patients with initial beyond-MC status. Independent factors for recurrence beyond-MC status included preoperative disease beyond the MC, the presence of microsatellite or multiple tumours and lymphovascular invasion (all: P < 0.001). A clinical risk score was used to predict survival and the likelihood of recurrence beyond the MC; patients with scores of 0, 1, 2 and 3 had 5- year incidence of recurring beyond-MC of 9.0%, 29.5%, 48.8% and 75.4%, respectively (P < 0.0001).Regardless of initial MC status, at 5 years the majority of patients remained disease-free or experienced recurrence within the MC after LR, and thus were potentially eligible for salvage transplantation (ST). Incorporating clinicopathological parameters into the MC allows for better risk stratification, which improves the selection of patients for ST and identifies patients in need of closer surveillance.

Project description:BACKGROUND AND AIM:To evaluate the effect of intermittent pringle maneuver (IPM) on the long-term prognosis and recurrence of hepatocellular carcinoma (HCC). METHODS:Eligible studies were identified by PubMed and other databases from Jan 1st 1990 to Mar 31st 2019. Hazard ratios (HR) with 95% confidence interval (CI) were calculated to evaluate the effects of IPM on the long-term prognosis and recurrence of patients with HCC. RESULTS:Six studies were enrolled in this meta-analysis. Results showed that there were no differences between IPM group and non-IPM group in the pooled HRs for the overall survival (OS) and disease-free survival (DFS) (HR 1.04, 95%CI 0.84~1.28, P = 0.74; HR 0.93, 95%CI 0.81~1.07, P = 0.29; respectively). However, subgroup analysis showed that the pooled Odd ratios (OR) for the 1-year OS and DFS rates of the IPM group when compared with the non-IPM group were 0.65 (95% CI 0.45~0.94, P = 0.02), 0.38 (95% CI 0.20~0.72, P = 0.003), respectively. In addition, there were no significant differences in the proportions of liver cirrhosis, HBsAg (+), Child-Pugh A class, multiple tumor, vascular invasion, and major hepatectomy between groups of IPM and non-IPM. CONCLUSION:Since IPM would increase the risk of early-recurrence, it should be used cautiously in the procedure of hepatectomy for resectable HCC. However, the current conclusion needs further validation. TRIAL REGISTRY NUMBER:CRD 42019124923.

Project description:The incidence of hepatocellular carcinoma (HCC) is increasing worldwide, largely due to hepatitis B virus (HBV), hepatitis C virus and liver cirrhosis. Chronic HBV infection is estimated to cause 55%-60% of the cases of HCC worldwide and over 70% in Asian countries. Liver resection is currently the mainstay of treatment due to the low surgical mortality, a wider treatment indication, and simplicity of post-treatment follow-up. There is an ever-increasing demand on surgeons to perform curative liver resection in HCC, with the hope of avoiding tumor recurrences. Hepatitis B-related-HCC has distinct clinicopathological features, which should be considered when treating the disease. The author presents a review of the recently evolving strategies and emerging therapies to improve HCC postresectional outcomes and focus on perioperative measures to improve patient outcome, with particular reference to the current status of adjuvant therapies in HCC patients after liver resection.

Project description:Introduction: Following the resection of brain metastases (BM), whole-brain radiotherapy (WBRT) is a long-established standard of care. Its position was recently challenged by the less toxic single-session radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT) of the resection cavity, reducing dose exposure of the healthy brain. Patients and Methods: We analyzed 101 patients treated with either SRS/FSRT (n = 50) or WBRT (n = 51) following BM resection over a 5-year period. Propensity score adjustment was done for age, total number of BM, timepoint of BM diagnosis, controlled primary and extracranial metastases. A Cox Proportional Hazards model with univariate and multivariate analysis was fitted for overall survival (OS), local control (LC) and distant brain control (DBC). Results: Median patient age was 61 (interquartile range, IQR: 56-67) years and the most common histology was non-small cell lung cancer, followed by breast cancer. 38% of the patients had additional unresected BM. Twenty-four patients received SRS, 26 patients received FSRT and 51 patients received WBRT. Median OS in the SRS/FSRT subgroup was not reached (IQR NA-16.7 months) vs. 12.6 months (IQR 21.3-4.4) in the WBRT subgroup (hazard ratio, HR 3.3, 95%-CI: [1.5; 7.2] p < 0.002). Twelve-months LC-probability was 94.9% (95%-CI: [88.3; 100.0]) in the SRS subgroup vs. 81.7% (95%-CI: [66.6; 100.0]) in the WBRT subgroup (HR 0.2, 95%-CI: [0.01; 0.9] p = 0.037). Twelve-months DBC-probabilities were 65.0% (95%-CI: [50.8; 83.0]) and 58.8% (95%-CI: [42.9; 80.7]), respectively (HR 1.4, 95%-CI: [0.7; 2.7] p = 0.401). In propensity score-adjusted multivariate analysis, incomplete resection negatively impacted OS (HR 3.9, 95%-CI: [2.0;7.4], p < 0.001) and LC (HR 5.4, 95%-CI: [1.3; 21.9], p = 0.018). Excellent clinical performance (HR 0.4, 95%-CI: [0.2; 0.9], p = 0.030) and better graded prognostic assessment (GPA) score (HR 0.4, 95%-CI: [0.2; 1.0], p = 0.040) were prognostic of superior OS. A higher number of BM was associated with a greater risk of developing new distant BM (HR 5.6, 95%-CI: [1.0; 30.4], p = 0.048). In subgroup analysis, larger cavity volume (HR 1.1, 95%-CI: [1.0; 1.3], p = 0.033) and incomplete resection (HR 12.0, 95%-CI: [1.2; 118.3], p = 0.033) were associated with inferior LC following SRS/FSRT. Conclusion: This is the first propensity score-adjusted direct comparison of SRS/FSRT and WBRT following the resection of BM. Patients receiving SRS/FSRT showed longer OS and LC compared to WBRT. Future analyses will address the optimal choice of safety margin, dose and fractionation for postoperative stereotactic RT of the resection cavity.

Project description:The value of preoperative transcatheter arterial chemoembolization (TACE) for patients with recurrent hepatocellular carcinoma (rHCC) after liver resection is uncertain. We aimed to determine its effect on postoperative complication and survival. There were 33 patients who received preoperative TACE and repeated liver resection (TACE-LR) and 119 patients who received repeated liver resection (LR) alone for rHCC. Seventy-eight patients (TACE-LR, 28; LR, 50) were identified by propensity score matching (PSM) analysis for comparison of postoperative complication, disease-free survival (DFS) and overall survival (OS). Univariable and multivariable analyses were used to identify predictors for survival. Before matching, the TACE-LR group had more intraoperative blood loss than the LR group (P < 0.05). After matching, the TACE-LR group had more intraoperative blood loss and a longer operation time (Both P < 0.05). In all and matched patients, both groups had similar postoperative complications rate (TACE-LR, 21.2%; LR, 7.6%; P = 0.052 and TACE-LR, 21.4%; LR, 12.0%; P = 0.435), DFS (P = 0.81 and P = 0.41) and OS (P = 0.87 and P = 0.79). Preoperative TACE was not a predictor for DFS and OS in multivariable analyses. Preoperative TACE for resectable rHCC prolongs operating time and increases intraoperative blood loss without improving survival; thus, it should not be recommended as a routine procedure before repeated resection for patients with rHCCs.

Project description:Resection has been commonly utilized for treating huge hepatocellular carcinoma (HCC) with a diameter of ≥10 cm; however, a high rate of mortality is reported due to recurrence. The present study was designed to predict the recurrence following resection based on preoperative and postoperative machine learning models. In total, 1,082 patients with HCC who underwent liver resection in the Eastern Hepatobiliary Surgery Hospital cohort between January 2008 and December 2016 were divided into a training cohort and an internal validation cohort. In addition, 164 patients from Mengchao Hepatobiliary Hospital cohort between January 2014 and December 2016 served as an external validation cohort. The demographic information, and serological, MRI, and pathological data were obtained from each patient prior to and following surgery, followed by evaluating the model performance using the concordance index, time-dependent receiver operating characteristic curves, prediction error cures, and a calibration curve. A preoperative random survival forest (RSF) model and a postoperative RSF model were constructed based on the training set, which outperformed the conventional models, such as the Barcelona Clinic Liver Cancer (BCLC), the 8th edition of the American Joint Committee on Cancer (AJCC 8th) staging systems, and the Chinese stage systems. In addition, the preoperative and postoperative RSF models could also re-stratify patients with BCLC stage A/B/C or AJCC 8th stage IB/II/IIIA/IIIB or Chinese stage IB/IIA/IIB/IIIA into low-risk, intermediate-risk, and high-risk groups in the training and the two validation cohorts. The preoperative and postoperative RSF models were effective for predicting recurrence in patients with huge HCC following hepatectomy.

Project description:Background Adjuvant hepatic artery infusion chemotherapy (HAIC) has been shown to be beneficial to the patient outcomes in hepatocellular carcinoma (HCC). Methods Randomized controlled trials (RCTs) and non-RCTs were identified from six databases up to January 26, 2023. Patient outcomes were assessed using overall survival (OS) and disease-free survival (DFS). Data were presented as hazard ratios (HR, 95% confidence intervals, or CIs). Results The present systematic review included 2 RCTs and 9 non-RCTs with a total of 1290 cases. Adjuvant HAIC improved OS (HR of 0.69; 95% CI of 0.56–0.84; p < 0.01) and DFS (HR of 0.64; 95% CI of 0.49–0.83; p < 0.01). Subgroup analysis showed that HCC patients with portal vein invasion (PVI) or microvascular invasion (MVI) benefit from adjuvant HAIC in terms of OS ((HR of 0.43; 95% CI of 0.19–0.95; p < 0.01) and (HR of 0.43; 95% CI of 0.19–0.95; p = 0.0373), respectively) and DFS ((HR of 0.38; 95% CI of 0.21–0.69; p < 0.01) and (HR of 0.73; 95% CI of 0.60–0.88; p = 0.0125), respectively). Adjuvant HAIC with the oxaliplatin-based approach significantly improved OS (HR of 0.60; 95% CI of 0.36–0.84; p = 0.02) and (HR of 0.59; 95% CI of 0.43–0.75; p < 0.01), respectively). Conclusion This meta-analysis demonstrated that postoperative adjuvant HAIC was beneficial in HCC patients with PVI and MVI. It remains unclear whether HAIC can improve the survival outcome in all HCC patients after hepatic resection.

Project description:ObjectivesPatients undergoing lung resection are at risk of perioperative complications, many of which necessitate unplanned critical care unit admission in the postoperative period. We sought to characterize this population, providing an up-to-date estimate of the incidence of unplanned critical care admission, and to assess critical care and hospital stay, resource use, mortality, and outcomes.MethodsA multicenter retrospective cohort study of patients undergoing lung resection in participating UK hospitals over 2 years. A comprehensive dataset was recorded for each critical care admission (defined as the need for intubation and mechanical ventilation and/or renal replacement therapy), in addition to a simplified dataset in all patients undergoing lung resection during the study period. Multivariable regression analysis was used to identify factors independently associated with critical care outcome.ResultsA total of 11,208 patients underwent lung resection in 16 collaborating centers during the study period, and 253 patients (2.3%) required unplanned critical care admission with a median duration of stay of 13 (4-28) days. The predominant indication for admission was respiratory failure (68.1%), with 77.8% of patients admitted during the first 7 days following surgery. Eighty-seven (34.4%) died in critical care. On multivariable regression, only the diagnosis of right ventricular dysfunction and the need for both mechanical ventilation and renal-replacement therapy were independently associated with critical care survival; this model, however, had poor predictive value.ConclusionsAlthough resource-intensive and subject to prolonged stay, following unplanned admission to critical care after lung resection outcomes are good for many patients; 65.6% of patients survived to hospital discharge, and 62.7% were discharged to their own home.

Project description:Background The extent of hepatic resection In HCC depends on the remnant liver reserve or the proximity of the tumor to major vessels. In this study, we evaluated the effects of very close resection margins on postoperative recurrence. Methods Consecutive LR for HCC between 2003 and 2009 were studied. Patients were divided into groups with very narrow (≤1 mm) or wider (>1 mm) resection margins. Propensity score matching (PSM) was used to balance demographic, surgical, and pathological factors. Results 983 patients were included in the study. After PSM, 173 patients were analyzed in each group. 5-year tumor recurrence and survival rates were comparable. Most recurrences were multiple intrahepatic. Section margin recurrences were similar in both groups. By multivariate analysis, tumor size >5 cm was associated with a very narrow resection margin, whereas low platelet count and tumor macrovascular invasion were significant factors related to tumor recurrence. Conclusions Patients with very narrow surgical margins showed outcomes comparable to those with wider surgical margins. Most recurrences were multiple intrahepatic and associated with the degree of portal hypertension and adverse tumor biology. Although wide surgical margins should be aimed whenever possible, a narrow tumor-free margin resection still represents an effective therapeutic strategy.
