Although stage IIIC (any TN3M0) breast cancer is known to have a dismal prognosis, the clinical outcome of current standard management and the prognostic differences between N3a, N3b and N3c remain to be further investigated. Data from our center on pathologic N3 (pN3) (n=284) breast cancer and the US Surveillance, Epidemiology, and End Results (SEER) database on clinical N3 (cN3) (n=15,291) and M1 (n=23,623) breast cancer between January 2004 and December 2015 were systematically analyzed for clinicopathological characteristics and survival outcomes. In our institution, patients with pN3c had the worst survival, with 5-year OS and DFS rates of 52.4% and 41.5%, respectively. Patients with pN3b had a relatively good prognosis, with a 5-year OS rate of 75.3% vs 63.9% for the pN3a group (p=0.045). For DFS, the 5-year survival rate was 63.1% in the pN3b group compared with 40.3% in the pN3a group (p=0.030). In the US SEER database, patients with cN3c had the worst survival in the cN3 group, but the prognosis of cN3c was much better than that of M1. Similarly, patients with cN3b had a better prognosis compared with patients in other groups, with a 5-year OS rate of 68.9% vs 61.9% for the cN3a group (p<0.001) and a 5-year BCSS rate of 73.4% vs 67.1% for the cN3a group (p<0.001). Breast cancer patients with N3c had the worst clinical outcomes, while the prognosis of N3b patients was better than that of N3a patients. Breast cancer patients with N3c had the worst clinical outcomes, while the prognosis of N3b patients was better than that of N3a patients. Hepatocellular carcinoma (HCC) caused by hepatitis C virus (HCV) infection has become less and less due to the use of direct-acting antiviral agents (DAAs). Although it may be common to assume that eradication of the virus should improve the survival of HCC patients, large-scale randomized clinical data to support the correlation between viral load and prognosis are still lacking in China. The aim of the study was to evaluate the efficacy of antiviral therapy for HCC patients with active HCV infection. We retrospectively enrolled 80 HCC patients with active HCV infection. Active HCV infection was defined as positive for HCV antibody with detectable HCV RNA by polymerase chain reaction. Forty-four patients (55.0%) received interferon combined with ribavirin treatment and 23 patients achieved sustained virological response (SVR). The 1-year survival rate in patients who achieved SVR was the highest, followed by those with non-SVR after antiviral treatment, and those without antiviral therapy (1-year survival rate were 91.3%, 88.4%, and 73.1%, respectively, P = 0.012). In the univariate analysis, alcohol intake and alpha-fetoprotein >20 ng/mL were associated with lower overall survival (OS) (P = 0.025 and P = 0.044, respectively), while SVR after antiviral treatment was associated with longer OS (P = 0.016). In the multivariate analysis, only SVR after antiviral treatment was significantly associated with OS (P = 0.014). Our results ensured that the elimination of HCV substantially improved OS in HCC patients with active HCV infection, and the prognosis of those patients without antiviral therapy was poor. Our results ensured that the elimination of HCV substantially improved OS in HCC patients with active HCV infection, and the prognosis of those patients without antiviral therapy was poor. To evaluate the expression and function of long noncoding RNA (lncRNA) Prader-Willi region non-protein coding RNA 1 (PWRN1) in human glioblastoma (GBM). QRT-PCR was applied to assess PWRN1 expression in human GBM tumors and GBM cell lines. PWRN1 was overexpressed by lentiviral infection in LN-229 and U-251 cells to evaluate its effect on GBM cell proliferation and migration in vitro, and xenograft in vivo. The endogenously competing target of PWRN1, human microRNA-21-5p (hsa-miR-21-5p)
