Aim To explore the association of NFKB1 c.-798_-795delATTG (rs28362491), NFKBIA c.-949C > T (rs2233406), IL-8 c.-352-A > T (rs4073), IL-10 c.-854T > C (rs1800871), TNF c.-418G > A (rs361525), and TNF c.-488G > A (rs1800629) polymorphisms with breast cancer risk in an East Chinese population. Methods We conducted a case-control study including 975 study participants (474 breast cancer patients and 501 female controls without cancer) and genotyped the polymorphisms employing polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Logistic regression was used to assess the association of the polymorphisms with breast cancer risk. Results We found that the ins/del and del/del genotypes of NFKB1 polymorphism and TT genotype of IL-10 polymorphism significantly increased breast cancer risk (NFKB1 ins/del odds ratio [OR] 1.69, 95% [CI] 1.23-2.33, P = 0.001; NFKB1 del/del OR 2.42, 95% CI 1.72-3.42, P < 0.001; IL-10 TT OR 2.36, 95% CI 1.58-3.52, P < 0.001). On the other hand, the TT genotype of IL-8 polymorphism, GA and AA genotypes of TNF c.-418G > A polymorphism, and GA genotype of TNF c.- 488G > A polymorphism significantly reduced breast cancer risk (IL-8 TT OR 0.48, 95% CI 0.33-0.72, P < 0.001; TNF c.- 418 GA OR 0.58, 95% CI 0.41-0.80, P = 0.001; TNF c.-418 AA OR 0.38, 95% CI 0.14-0.98, P = 0.044; TNF c.-488 GA OR 0.68, 95% CI 0.48-0.96, P = 0.029). When stratified by menopausal status, the CT genotype of NFKBIA polymorphism significantly reduced the risk among pre-menopausal women (OR 0.63, 95% CI 0.40-0.99, P =, 043), but not among postmenopausal women. Conclusions NFKB1, NFKBIA, IL-8, IL-10, and TNF polymorphisms could serve as useful predictive biomarkers for breast cancer risk among women in East China. Source

Beclin 1, a key regulator of autophagy, has been found to be aberrantly expressed in a variety of human malignancies. Herein, we employed immunohistochemistry (IHC) to detect the protein expression of Beclin 1 in nonsmall cell lung cancer (NSCLC) and paired normal adjacent lung tissues, and analyzed its clinicopathological/prognostic significance in NSCLC. Receiver operating characteristic (ROC) curve analysis was utilized to determine a cutoff point (>2 VS. ≤2) for Beclin 1 expression in a training set (n = 105). For validation, the ROC-derived cutoff value was subjected to analysis of the association of Beclin 1 with patients' clinical characteristics and outcome in a testing set (n = 111) and the overall patient cohort (n = 216). Our data showed that Beclin 1 was significantly lower in NSCLC tissues compared with the adjacent normal tissues, negatively associating with tumor recurrence rate (65.8% VS 32.3%; p < 0.001). In the testing set and the overall patient cohort, low expression of Beclin 1 showed significantly inferior overall survival (OS) (p < 0.001) and progression-free survival (PFS) (p < 0.001) compared to high expression of Beclin 1. In the testing set and the overall patient cohort, the median duration of OS for patients with high and low expression of Beclin 1 was 108 VS. 24.5 months (p < 0.001) and 108 VS. 28 months (p < 0.001), respectively. Furthermore, low expression of Beclin 1 was also a poor prognostic factor within each stage of NSCLC patients. Multivariate analysis identified that Beclin 1 was an independent prognostic factor for NSCLC. Our findings in the present study provided evidence that Beclin 1 may thus emerge as an independent prognostic biomarker in this tumor entity in the future. © 2013 Zhou et al. Source

Triple negative breast cancer (TNBC) acquires an unfavorable prognosis, emerging as a major challenge for the treatment of breast cancer. In the present study, 122 TNBC patients were subjected to analysis of Aurora-A (Aur-A) expression and survival prognosis. We found that Aur-A high expression was positively associated with initial clinical stage (P = 0.025), the proliferation marker Ki-67 (P = 0.001), and the recurrence rate of TNBC patients (P<0.001). In TNBC patients with Aur-A high expression, the risk of distant recurrence peaked at the first 3 years and declined rapidly thereafter, whereas patients with Aur-A low expression showed a relatively constant risk of recurrence during the entire follow-up period. Univariate and multivariate analysis showed that overexpression of Aur-A predicted poor overall survival (P = 0.002) and progression-free survival (P = 0.012) in TNBC. Furthermore, overexpression of Aur-A, associated with high Ki-67, predicted an inferior prognosis compared with low expression of both Aur-A and Ki-67. Importantly, we further found that Aur-A was overexpressed in TNBC cells, and inhibition of this kinase inhibited cell proliferation and prevented cell migration in TNBC. Our findings demonstrated that Aur-A was a potential therapeutic target for TNBC and inhibition of Aur-A kinase was a promising regimen for TNBC cancer therapy. © 2013 Xu et al. Source

Transcatheter arterial chemoembolization (TACE) is the conventional treatment for patients with unresectable hepatocellular carcinoma (HCC), but few studies to date have demonstrated the use of TACE as an examination method for uneasily detected HCC. The present study describes an unusual case of HCC with TACE as an examination method. A 41‑year‑old male presented with an elevated α‑fetoprotein level (AFP) of 3,635 ng/ml, however, no tumor lesions were detected by B‑mode ultrasound, computed tomography (CT) or digital subtraction angiography. During TACE treatment, two tumor lesions of ~0.5 and 0.8 cm were revealed in the right liver lobe, with no tumors in the left liver lobe. A month after TACE, a liver CT scan found 11 lesions (8 in the right liver lobe and 3 in the left liver lobe). The HCC patient's AFP levels decreased to an almost normal level following the TACE treatment. This study provokes consideration of the application of TACE in the diagnosis and treatment of HCC patients with liver lesions that are hard to detect by conventional means. © 2015, Spandidos Publications.
