Short Term Survival

Background: In patients with a large, unresectable hepatocellular carcinoma (HCC), the primary recommendation is for transarterial chemoembolization (TACE) but used alone TACE is not typically curative. Combinations of TACE followed in a delayed fashion by single-applicator thermal ablation have also been suboptimal. As an alternative, we investigated the combination of TACE followed within 1–3 days by multi-antenna microwave ablation (MWA) in patients with a large HCC, to determine the feasibility, safety, local control, and short-term survival rates of this approach. Methods: We retrospectively studied 43 patients with a large HCC (mean diameter, 8.8 cm; SD, 2.8 cm) treated between July 2015 and July 2018, who underwent TACE followed within 3 days by multi-antenna simultaneous MWA. We measured the liver and renal function before and after treatment, recorded complications, used three-dimensional software and imaging to calculate tumor necrosis rates at 1 month after therapy, and calculated overall survival (OS) and progression-free survival (PFS) using the Kaplan–Meier method. Results: Mean follow up was 12.2 (range, 3.5–35.6) months. All patients completed the treatment protocol. At 1 month after combined therapy, tumor necrosis was complete in 16 (37.2%), nearly complete in 19 (44.2%), and partial in 8 (18.6%) patients. The 1- and 2-year OS rates were 64.0% and 46.8%, respectively, with a median OS of 23.0 months; and the 1- and 2-year PFS rates were 19.9% and 4.4%, respectively, with a median PFS of 4.2 months. A transient change in liver function occurred 3 days after MWA but resolved within 1 month. Only two patients had major complications, which were treatable and resolved. Conclusion: Multi-antenna MWA-oriented combined therapy is feasible and well tolerated, and it results in satisfactory initial local control and short-term survival in some but not all patients with a large HCC.

Abstract Objective Here we performed the Bioinformatics analysis on the data from The Cancer Genome Atlas (TCGA), in order to find the correlation between the expression of ATP Binding Cassette (ABC) Transporters’ genes and hepatocellular carcinoma (HCC) prognosis; Methods Transcriptome profiles and clinical data of HCC were obtained from TCGA database. Package edgeR was used to analyze differential gene expression. Patients were divided into low-ABC expression and high-ABC expression groups based on the median expression level of ABC genes in cancer. The overall survival and short-term survival (n= 341) of the two groups was analyzed using the log-rank test and Wilcoxon test; Results We found that ABC gene expression was correlated with the expression of PIK3C2B (p<0.001, ABCC1: r=0.27; ABCC10: r=0.57; ABCC4: r=0.20; ABCC5: r=0.28; ABCB9: r=0.17; ABCD1: r=0.21). All patients with low-ABC expression showed significantly increased overall survival. Significantly decreased overall survival (Log-rank test: p<0.05, Wilcoxon test: p<0.05) was found in patients with high expression of ABCC1 (HR=1.58), ABCD1 (HR=1.45), ABCC4 (HR=1.56), and ABCC5 (HR=1.64), while decreased short-term survival (Log-rank test: p>0.05, Wilcoxon test: p<0.05) was correlated with the increased expression of ABCC10 (HR=1.29), PIK3C2B (HR=1.29) and ABCB9 (HR=1.23); Conclusions Our findings indicate that the specific ABC gene expression correlates with the prognosis of HCC. Therefore, ABC expression profile could be a potential indicator for HCC patients.

Short Term Survival

Backgrounds In recent years, low levels of Insulin-like Growth Factor-1 (IGF-1) have been suggested to be associated with higher risks of developing heart failure and higher long-term mortality rates following Acute Myocardial Infarction (AMI). However, the effect of IGF-1 levels on short-term survival has been rarely studied. In this study we aimed to assess any possible association between serum IGF-1 concentration following AMI and short-term survival rates. Methods In this study, serum total IGF-1 levels were measured in 56 patients within 24 hours following AMI and were compared to 56 individuals with no cardiovascular disease. Patients were followed up to death or discharge from hospital (median = 6 days) and survival curves were compared based on median IGF-1 value. Results Mean (±SD) of serum IGF-1 levels were 232.73 ng/ml (±81.74) and 211.00 ng/ml (±58.22) in survived and expired patients respectively and the difference was not statistically significant ( P value = 0.501). The difference between survival curves was also not statistically significant ( P value = 0.246). Conclusion According to findings of this study, serum total IGF-1 concentration does not seem to be associated with short-term survival rates.
