Breast Cancer Research and Treatment | Year: 2013

The purpose of this study is to evaluate the efficacy and safety of docetaxel plus cyclophosphamide (TC) compared with docetaxel, anthracycline, and cyclophosphamide (TEC) in neoadjuvant treatment of triple negative or HER2 positive breast cancer. Eligible breast cancer patients were randomized to receive six cycles of TC or TEC. The primary end point was pathological complete remission (pCR). Secondary end points included safety, clinical response rate, and survival outcome. One hundred and two patients were initially randomized and 96 patients were available for efficacy analysis. 96.9 % patients were treated with epirubicin as an anthracycline agent. pCR rates were 6.8 % (3/45) and 17.6 % (9/51) in TC and TEC group, respectively, P = 0.113. After a mean follow up of 20 (3-36) months, non-anthracycline-containing TC regimen treatment resulted in a worse event-free survival (adjusted hazard ratio [HR] 2.42; 95 % CI 1.11-5.30) and disease-free survival (HR 2.85; 95 % CI 1.21-6.74) compared with TEC regimen, which was more apparent in triple negative subtype. Severe adverse event rates were similar, except that patients treated with TEC had a higher rate of neutropenia and leucopenia. TEC treatment had a superior survival outcome and trend of higher pCR rate compared with TC in this trial setting, especially in triple negative subtype, which deserves further validation. © 2013 Springer Science+Business Media New York.

Berberine is one of the main alkaloids found in the Chinese herb Huang lian (Rhizoma Coptidis), which has been reported to have multiple pharmacological activities. This study aimed to analyze the molecular targets of berberine based on literature data followed by a pathway analysis using the PANTHER program. PANTHER analysis of berberine targets showed that the most classes of molecular functions include receptor binding, kinase activity, protein binding, transcription activity, DNA binding, and kinase regulator activity. Based on the biological process classification of in vitro berberine targets, those targets related to signal transduction, intracellular signalling cascade, cell surface receptor-linked signal transduction, cell motion, cell cycle control, immunity system process, and protein metabolic process are most frequently involved. In addition, berberine was found to interact with a mixture of biological pathways, such as Alzheimer's disease-presenilin and -secretase pathways, angiogenesis, apoptosis signalling pathway, FAS signalling pathway, Hungtington disease, inflammation mediated by chemokine and cytokine signalling pathways, interleukin signalling pathway, and p53 pathways. We also explored the possible mechanism of action for the anti-diabetic effect of berberine. Further studies are warranted to elucidate the mechanisms of action of berberine using systems biology approach. © 2012 Xiao-Wu Chen et al.

The aim of the present study was to examine the effects of acute infrasound exposure on oxidative damage and investigate the underlying mechanisms in rat cardiomyocytes. Neonatal rat cardiomyocytes were cultured and exposed to infrasound for several days. In the study, the expression of CAT, GPx, SOD1, and SOD2 and their activities in rat cardiomyocytes in infrasound exposure groups were significantly decreased compared to those in the various time controls, along with significantly higher levels of O2 - and H 2O2. Decreased cardiac cell viability was not observed in various time controls. A significant reduction in cardiac cell viability was observed in the infrasound group compared to the control, while significantly increased cardiac cell viability was observed in the infrasound exposure and rosiglitazone pretreatment group. Compared to the control, rosiglitazone significantly upregulated CAT, GPx, SOD1, and SOD2 expression and their activities in rat cardiomyocytes exposed to infrasound, while the levels of O2 - or H2O2 were significantly decreased. A potential link between a significant downregulation of PPAR-γ expression in rat cardiomyocytes in the infrasound group was compared to the control and infrasound-induced oxidative stress. These findings indicate that infrasound can induce oxidative damage in rat cardiomyocytes by inactivating PPAR-γ. © 2013 The Author(s).

Objective: To evaluate the effect of neoadjuvant chemotherapy (NAC) by investigating the expression of cyclin D1 in human breast cancer before and after NAC. Methods: Eighty-four cases of breast cancer were diagnosed by core biopsies. The expression level of cyclin D1 in cancer tissues was measured by immunohistochemical envision two-step method before and after NAC (pirarubicin and docetaxel regimen for 3-4 cycles). Results: Complete remission (CR) occurred in 4 cases of 84 patients (4.76%) with 2 pathological complete response cases, partial response (PR) in 54 cases (64.29%), stability (SD) in 26 cases (30.95%) and no disease progression (PD) patients. The positive rate of cyclin D1 in cancer tissues [65.48% (55/84)] was significantly decreased after NAC [39.29% (33/84)] (χ2 = 11.55, P = 0.001). In clinical level, the ease rate was significantly improved in patients whose cyclin D1 expression switched from positive [86.36% (19/22)] to negative [45.45% (15/33)] after NAC treatment (χ2 = 9.359, P = 0.002). Conclusion: NAC significantly decreases the expression of cyclin D1 in breast cancer tissues. Meanwhile, the ease rate is improved when cyclin D1 expression switched from positive to negative after NAC. Therefore, cyclin D1 expression can be used as an evaluation index for the efficiency of NAC.

Recent evidence has suggested that cigarette smoking is associated with an increased prevalence of heart diseases. Given that cigarette smoking triggers proinflammatory response via stimulation of the capsaicin-sensitive transient receptor potential cation channel TRPV1, this study was designed to evaluate the effect of an essential α,β-unsaturated aldehyde from cigarette smoke crotonaldehyde on myocardial function and the underlying mechanism with a focus on TRPV1 and mitochondria. Cardiomyocyte mechanical and intracellular Ca 2+ properties were evaluated including peak shortening (PS), maximal velocity of shortening/relengthening (±dL/dt), time-to-PS (TPS), time-to-90% relengthening (TR90), fura-2 fluorescence intensity (FFI), intracellular Ca2+ decay and SERCA activity. Apoptosis and TRPV1 were evaluated using Western blot analysis. Production of reactive oxygen species (ROS) and DNA damage were measured using the intracellular fluoroprobe 5-(6)-chloromethyl-2′,7′-dichlorodihydrofluorescein diacetate and 8-hydroxy-2′-deoxyguanosine (8-OHdG), respectively. Our data revealed that crotonaldehyde interrupted cardiomyocyte contractile and intracellular Ca 2+ property including depressed PS, ±dL/dt, ΔFFI and SERCA activity, as well as prolonged TR90 and intracellular Ca 2+ decay. Crotonaldehyde exposure increased TRPV1 and NADPH oxidase levels, promoted apoptosis, mitochondrial injury (decreased aconitase activity, PGC-1α and UCP-2) as well as production of ROS and 8-OHdG. Interestingly, crotonaldehyde-induced cardiac defect was obliterated by the ROS scavenger glutathione and the TRPV1 inhibitor capsazepine. Capsazepine (not glutathione) ablated crotonaldehyde-induced mitochondrial damage. Capsazepine, glutathione and the NADPH inhibitor apocynin negated crotonaldehyde-induced ROS accumulation. Our data suggest a role of crotonaldehyde compromises cardiomyocyte mechanical function possibly through a TRPV1-and mitochondria-dependent oxidative stress mechanism. © 2014 Elsevier Ltd.

Results: Univariate and multivariate analysis revealed that higher LMR levels (≥4.25) were significantly associated with favorable DFS (P = 0.009 and P = 0.011, respectively). Additionally, univariate analysis revealed that a higher lymphocyte count (≥1.56109/L) showed borderline significance for improved DFS (P = 0.054), while a lower monocyte count (< 0.4×109/ L) was associated with a significantly better DFS ( P = 0.010).Conclusions: An elevated pre-NCT peripheral LMR level was a significantly favorable factor for locally advanced breast cancer patient prognosis. This easily obtained variable may serve as a valuable marker to predict the outcomes of locally advanced breast cancer.Purpose: Neoadjuvant chemotherapy (NCT) is a standard treatment option for locally advanced breast cancer. However, the lack of an efficient method to predict treatment response and patient prognosis hampers the clinical evaluation of patient eligibility for NCT. An elevated lymphocyte-to-monocyte ratio (LMR) has been reported to be associated with a favorable prognosis for certain hematologic malignancies and for nasopharyngeal carcinoma; however, this association has not been investigated in breast cancer. The purpose of this study was to evaluate whether pre-NCT LMR analysis could predict the prognosis of patients with locally advanced breast cancer.Methods: A retrospective cohort of 542 locally advanced breast cancer patients (T3/T4 and/or N2/N3 disease) receiving NCT followed by radical surgery was recruited between May 2002 and August 2011 at the Fudan University Shanghai Cancer Center. Counts for pre-NCT peripheral absolute lymphocytes and monocytes were obtained and used to calculate the LMR. © 2014 Ni et al.

Background: Mammographic density (MD) has not been systematically investigated among Chinese women. Breast cancer screening programmes provided detailed information on MD in a large number of asymptomatic women. Methods: In the Multi-modality Independent Screening Trial (MIST), we estimated the association between MD and its influential factors using logistic regression, adjusting for age, body mass index (BMI) and study area. Differences between Chinese and other ethnic groups with respect to MD were also explored with adjustment for age and BMI. Results: A total of 28 388 women aged 45 to 65 years, who had been screened by mammography, were enrolled in the study. Of these, 49.2% were categorized as having dense breasts (BI-RADS density 3 and 4) and 50.8% as fatty breasts (BI-RADS density 1 and 2). Postmenopausal status [odds ratio (OR)=0.66; 95% confidence interval (CI): 0.62-0.70] and higher number of live births (OR=0.56; 95% CI: 0.46-0.68) were inversely associated with MD, whereas prior benign breast disease (OR=1.48; 95% CI: 1.40-1.56) and later age at first birth (OR=1.17; 95% CI: 1.08-1.27) were positively associated with MD. In comparison with the data from the Breast Cancer Surveillance Consortium, we found that women in MIST were more likely to have fatty breasts than Americans (from the Breast Cancer Surveillance Consortium) in the older age group (>50 years) but more likely to have dense breasts in the younger age group (<50 years). Conclusions: This study suggests that several risk factors for breast cancer were associated with breast density in Chinese women. Information on the determinants of mammographic density may provide valuable insights into breast cancer aetiology. © The Author 2014; Published by Oxford University Press on behalf of the International Epidemiological Association all rights reserved.

Recent studies have revealed that the receptor activator of nuclear factor-kappa B ligand/RANK/osteoprotegerin (RANKL/RANK/OPG) system has an important role in vascular calcification, which is contributory to various cardiovascular diseases and intimately linked to the regulation of blood pressure. Therefore, we performed a case-control study to investigate the associations of 21 single-nucleotide polymorphisms (SNPs) in the TNFSF11, TNFRSF11A and TNFRSF11B genes in the RANKL/RANK/OPG system with hypertension and blood pressure in post-menopausal Chinese women. In this study, 503 hypertensive patients and 509 normal controls were recruited. Genotyping was performed using the high-throughput Sequenom genotyping platform. The results showed that two SNPs (rs6567270 and rs4603673) in the TNFRSF11A were associated with hypertension (P=0.010 and P=0.013, respectively) and systolic blood pressure (P=0.024 and P=0.023, respectively). One SNP (rs9646629) in the TNFRSF11A showed significant association with diastolic blood pressure (P=0.031). The results of this study suggest that TNFRSF11A but not TNFSF11 and TNFRSF11B genetic variation is associated with hypertension and blood pressure in Chinese women. The findings provide additional support for the genetic role of RANKL/RANK/OPG system in hypertension and blood pressure regulation. © 2015 Macmillan Publishers Limited.

To determine the preliminary effectiveness of breast cancer screening among Chinese females, 1226714 women aged 35-69 years first received clinical breast examinations. Urban women with suspected cancer received mammography followed by breast ultrasound (BUS), while rural suspected women underwent BUS followed by mammography. After one-year follow-up, 223 and 431 breast cancers were detected among urban and rural women (respectively), with overall detection rates of 0.56/1000 and 0.52/1000. Higher detection rates were significantly associated with older age at screening for both urban and rural women; additionally, urban women were at significantly higher risk if they had no job, no insurance, or were obese; additional risk factors specific to rural women included Han nationality, higher income, being unmarried, and having a family history of cancer (all P values<0.05). Among screening-detected breast cancers in urban vs. rural women, 46.2% and 38.8% (respectively) were early stage, 62.5% and 66.3% were 2 centimeters, 38.0% and 47.3% included lymph-node involvement, and 14.0% and 6.0% were identified as carcinoma in situ. All abovementioned cancer characteristics were significantly better than clinic-detected cancers (all P values<0.001). In conclusion, several important differences were found between urban and rural women in screening effectiveness and patterns of cancer distribution.

To investigate the current status of smoking and passive smoking among Chinese females to provide evidence for related strategy development.Data from 32 720 women aged 45-65 years old who participated in the 2008 to 2010 Chinese Multi-center Women Breast Cancer Screening Project, were used to analyze the prevalence rates of smoking/heavy smoking, daily smoking, smoking cessation, successful smoking cessation, passive smoking, etc.A total of 913 females, accounted for 2.8% of all the women in the study, had reported the history of smoking. There were significant differences seen regarding the prevalence rates of smoking in different regions (Beijing, 2.8%; Tianjin, 5.9%; Nanchang, 1.7%; Feicheng, 0.9%; Shenyang, 1.8%). The prevalence rates of current smoking, daily smoking, and heavy smoking were 1.8%, 1.0% and 0.2%, respectively. The prevalence rates of smoking and current smoking increased with age but not the prevalence rates of daily smoking and heavy smoking. Among the smokers, the median initiation age of smoking, the median daily cigarette per day, and median year of smoking were 30 years old, 10 cigarette, and 16 years, respectively. And the prevalence rates of smoking cessation and successful smoking cessation were 19.1% and 8.2%. The prevalence rate of passive smoking was 45.7% (12 730/27 874). After combing the number of smokers and the number of passive smokers, the total exposure rate to tobacco was 41.8% (13 670/32 720).There was a relatively low level of smoking among Chinese females, so as the rate of smoking cessation. However, passive smoking presented a relatively high level among Chinese females.
