The aim of the present study was to assess the association between the efficacy and adverse events (AEs) of transcatheter arterial chemoembolization (TACE) combined with sorafenib in patients with unresectable hepatocellular carcinoma (HCC). Between July 2008 and May 2011, 50 patients with unresectable HCC were enrolled and assigned to receive TACE combined with sorafenib in the present study. The primary outcomes were considered as time to disease progression (TTP) and sorafenib-related AEs. In the present study, 34 of 50 patients had disease progression with a median TTP (mTTP) of 210 days. The most common AEs included hand-foot skin reaction (HFSR), fatigue, diarrhea and hypertension. The mTTP of patients with HFSR extended 140 days compared to that of the patients without HFSR. Kaplan-Meier analysis was used for mTTP between the two groups of patients. This difference was statistically significant when analyzed by the univariate COX proportional hazards regression model. In conclusion, TACE in combination with sorafenib had an acceptable safety profile in the treatment of unresectable HCC. Additionally, it also revealed that HFSR served as a good prognostic predictor in using combination therapy. Therefore, discontinuation of sorafenib treatment should be prevented to avoid disease progression. [ABSTRACT FROM AUTHOR]

A number of epidemiological studies have suggested that obesity is associated, albeit inconsistently, with the incidence of prostate cancer (PCa). In order to provide a quantitative assessment of this association, the present study examined the correlation between obesity and the incidence and associated mortalities of PCa in an updated meta-analysis of cohort studies. The cohort studies were identified by searching the EMBASE and MEDLINE databases on January 1, 2014. The summary relative risks (RRs) with 95% confidence intervals (CIs) were calculated using random-effects models. In total, 17 studies, which included 3,569,926 individuals overall, were selected according to predefined inclusion criteria. Based upon the results of the random-effects models, obesity was not significantly correlated with the incidence of PCa (RR, 1.00; 95% CI, 0.95-1.06). However, further analysis revealed that obesity was signifi- cantly correlated with an increased risk of aggressive PCa (RR, 1.14; 95% CI, 1.04-1.25). Furthermore, an increased risk of PCa-associated mortality was significantly associated with obesity (RR, 1.24; 95% CI, 1.15-2.33), without any heterogeneity between the studies (I2=0.0%; P=0.847). The present study provides preliminary evidence to demonstrate that obesity is a significant risk factor for aggressive PCa and PCa-specific mortality. The low survival rates observed among obese males with PCa may be a likely explanation for this association. [ABSTRACT FROM AUTHOR]
