Changes in acute and late toxicity and patient-reported health-related quality of life following radiotherapy in women with breast cancer:A 1-year longitudinal study

Objective:The objective of this study was to investigate the frequency of acute and late toxicities,as well as changes in the quality of life(QOL)for breast cancer patients following radiotherapy(RT).Materials and Methods:A total of 108 breast cancer women were recruited for this prospective study.Data were collected at various intervals;prior to,and 1,3,6 months,and 1 year after radiation therapy.The primary outcomes were toxicity radiation therapy oncology group/European Organization for Research and Treatment of Cancer(EORTC)criteria.Our secondary outcome was QOL,measured using EORTC QLQ-C30 and Edmonton Symptom Assessment Scale.We employed Friedman’s two-way analysis to evaluate the changes in QOL over the course of 1 year.Results:The early toxicities that are most commonly experienced include pharyngeal,skin,and mucous membrane toxicity.Late toxicities frequently involve skin and submucosal toxicity.To measure patient functionality,all functional subscale scores except for the patient’s emotional state increased over time compared to pre-RT.Symptoms of the patients,which were included in the QOL symptom scale,decreased during the follow-up period,except for fatigue;however,changes in pain,insomnia,and loss of appetite did not significantly change.We identified the analogous symptom profiles in Edmonton.Although patients’overall health scores declined in the 1st and 3rd months after radiotherapy(RT),they rebounded at 6 and 12 months.Conclusion:For breast cancer patients,RT did not adversely affect functional capacity or exacerbate symptoms,but persistent fatigue did increase during the observation period.Health-care professionals ought to devise strategies to assist patients with skin toxicity and fatigue.

Analysis of the psychological conditions and related factors of breast cancer patients

Sufferers of breast cancer are often plagued by various psychological problems. Mastectomy, which has a serious influence on the female sex characteristics, can bring about especially serious psychological problems. These problems affect not only the patients’ quality of life but also the beginning, development, and end of the disease. This paper reviewed the relationships between the patients’ personal factors, the disease itself, treatment factors, and other socio-psychological factors and psychological conditions so as to provide new ideas for the psychological intervention on breast cancer patients, comprehensive clinical diagnosis and treatment, and prevention and cure.

Diagnosis and treatment of peripherally inserted central catheters(PICC)-related sepsis in breast cancer patients carrying PICC catheter for chemotherapy

Objective:The aim of our research was to study the incidence,clinical diagnosis and treatment of peripherally inserted central catheters(PICC)-related sepsis in breast cancer patients carrying PICC catheter for chemotherapy.Methods:The data of the incidence,diagnosis and treatment of PICC-related sepsis in 215 cases of breast cancer patients carrying PICC catheter for chemotherapy in our hospital from August,2009 to September,2011 were analyzed retrospectively.Results:216 PICCs had been successfully applied in 215 cases of breast cancer patients and followed for a total of 19,109 catheter days,(median catheterization duration,88.9 days,range 1-212 days).Among those,3(1.39%) PICCs were removed respectively as a result of PICC-related sepsis in 29,73 and 108 catheter-days(median 70 d),with a rate of 0.16 per 1000 catheter-days.Conclusion:Chemotherapeutic treatment via PICC for breast cancer patients is one of the most secure and effective measures but there exists small number of cases in which PICC catheter related sepsis is possible.Careful observation of relevant symptoms and signs,early diagnosis and treatment,not relying completely on blood culture tests and timely removal of PICC catheter can be very effective in treating PICC-related sepsis in these patients.

Molecular mechanisms of Baihedihuang decoction as a treatment for breast cancer related anxiety:A network pharmacology and molecular docking study

BACKGROUND The therapeutic effects of a combination of Chinese medicines called Baihedihuang decoction(BD)have been clinically verified,although its molecular targets in breast cancer related anxiety remain unknown.AIM To explore the molecular mechanisms of BD for breast cancer related anxiety treatment.METHODS We used the Traditional Chinese Medicine Systems Pharmacology database to screen the active ingredients and potential targets of BD,and constructed the"drug-ingredient-target"network map with the help of Cytoscape 3.8 software.Also,we used the Online Mendelian Inheritance in Man,DrugBank,and Gencards databases to collect the disease targets of breast cancer related anxiety,and used the STRING platform to perform protein interaction analysis and construct the protein-protein interaction network.Metascape platform was used for Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis of key targets.Molecular docking technology was used to verify the drug component/target disease network.RESULTS We screened 16 active ingredients of BD for breast cancer related anxiety,with 113 target proteins.There are 931 disease targets of breast cancer related anxiety,and finally,43 key targets and 305 Kyoto Encyclopedia of Genes and Genomes pathways were generated.The main active ingredients of BD for breast cancer related anxiety are verbascoside,β-sitosterol,stigmasterol,catalpol,etc.CDK2,TP53,HTR2A,ESR1,etc.are its key targets,and the main involved signaling pathways may include neuroactive ligand-receptor interaction pathway,5-hydroxytryptaminergic synapse,P53 signaling pathway,cGMP-PKG signaling pathway,the cAMP signaling pathway,etc.Finally,molecular docking was performed with Vina software to validate the key active ingredients in BD with the selected key action targets.The molecular docking results showed that verbascoside,β-sitosterol,stigmasterol and CDK2 could stably bind and interact through amino acid residues SER249,ARG260,PRO228,ALA282,SER276,LYS273,ASN272,etc.CONCLUSION The therapeutic effect of BD for breast cancer related anxiety is multi-level,multi-target,and multi-pathway.The findings of this study provide ideas and basis for further research.

Presence of circulating tumor cells is associated with metabolic-related variables in postoperative patients with early-stage breast cancer

Objective：Although circulating tumor cells（CTCs）have been well-established as promising prognostic biomarkers in both early breast cancer and metastatic settings,little is known regarding the prognostic relevance of CTCs in the long-term postoperative monitoring of patients with non-metastatic breast cancer（non-MBC）.In this study,we investigated the associations of CTCs with clinicopathological features and metabolic-related variables,such as obesity and hyperglycemia.Methods：In this retrospective study,we recruited 264 patients with postoperative stage Ⅰ–Ⅲ breast cancer at Guangdong General Hospital from January 2009 to December 2015.The prevalence and number of CTCs were assessed using the Cell Search System at a median time of 19.0 months[interquartile range（IQR）,7.8–33.0]after surgery.The CTC assay results were correlated with the clinicopathological features and metabolic-related variables.A multivariate logistic regression analysis was performed to further determine the independent predictors of CTCs.Results：CTCs were detected in 10.6%of all patients.The positive rate of CTCs in patients with infiltrating ductal carcinoma was lower than that in patients with other pathological types（9.0%vs.28.6%,P=0.020）.More importantly,the presence of CTCs was correlated with blood glucose level（P=0.015）and high-density lipoprotein level（P=0.030）.The multivariate logistic regression analysis showed that the pathological type[odds ratio（OR）：1.757,95%CI：1.021–3.023;P=0.042]and blood glucose level（OR：1.218,95%CI：1.014–1.465;P=0.035）were independent predictors of the presence of CTCs.Conclusions：This study revealed potential associations between CTCs and metabolic-related factors in Chinese patients with non-MBC and supports the hypothesis that metabolic dysfunction in breast cancer patients might influence the biological activity of metastatic breast cancer,leading to a higher prevalence of CTCs.

The relationship between psychological distress with salivary <i>α</i>-amylase and stress related symptoms among breast cancer survivors

Background and Aims: This study examined the stress levels, the stressors and biomarker such as Alpha (α)-Amylase enzyme which is secreted under distress conditions. The aim was to determine the relationship between these three variables. Methods: The study respondents were made up of cancer outpatients from 3 hospitals namely the Hospital Kuala Lumpur, Seberang Jaya and Johor Baru, Pantai Ipoh and Putrajaya. The Personal Stress Inventory (PSI) questionnaire was used to identify stressors, while the Hospital Anxiety and Depression Scale (HADS) were used to determine the psychological distress levels. The Salimentary Oral Swab (SOS) Technique was used to collect the saliva and then the Salivary α-Amylase Assay Kit was used to analyse for α amylase. Results: The majority of respondents were stressed due to their sensitive emotion and nervousness in their daily lives (68.7%), they had poor memory and short attention spans of carrying out job tasks (67.3%) as well as they were emotionally depressed (65.3%). Their poor memory and short attention span (p = 0.037), heavy work load and poor task delivery (p = 0.008) were predictors for distress using HADS. The salivary α-amylase concentration was significantly related to the stress levels (p = 0.002). Conclusion: Breast cancer respondents with musculoskeletal system related symptoms, with heavy work load and poor task delivery, as well as had poor memory and short attention span were at higher risk of experiencing psychological distress. The salivary α-amylase which had significant relationships with psychological distress was therefore, a potential biological indicator for distress, while the musculoskeletal system related symptoms from the PSI questionnaire were predictors for distress.

Perceived health-related stigma among patients with breast cancer

Breast cancer survivors face many challenges(particularly changes in body image) on their road to restoring physical and psychosocial health following diagnosis. Perceived health-related stigma(PHS)refers to the attachment of negative connotations to some types of disease diagnoses. PHS is common among patients with breast cancer and is associated with adverse emotions, attitudes and behaviors. This article summarizes the latest advances and new perspectives on PHS of breast cancer patients and approaches to block this deleterious process. Effects of PHS on patients with breast cancer, in this paper,and measures, predictors and interventions of PHS have been discussed in depth. Future studies should continue to develop more effective instruments that are specialized for measuring PHS of breast cancer patients, explore the predictors of PHS, and discuss effective interventions on the basis of the predictors.

Cancer risk in relatives of BRCA1/2 pathogenic variant carriers in a large series of unselected patients with breast cancer

Objective:The spectrum and risk of cancer in relatives of BRCA1/2 pathogenic variant carriers in the Chinese population have not been established.Methods:A family history of cancer in 9903 unselected breast cancer patients was retrospectively analyzed.BRCA1/2 status was determined for all patients and relative risks(RRs)were calculated to evaluate cancer risk in relatives of the patients.Results:The incidences of breast cancer in female relatives of BRCA1 carriers,BRCA2 carriers,and non-carriers were 33.0%,32.2%,and 7.7%,respectively.The corresponding incidences of ovarian cancer were 11.5%,2.4%,and 0.5%,respectively.The incidences of pancreatic cancer in male relatives of BRCA1 carriers,BRCA2 carriers,and non-carriers were 1.4%,2.7%,and 0.6%,respectively.The corresponding incidences of prostate cancer were 1.0%,2.1%,and 0.4%,respectively.The risks of breast and ovarian cancers in female relatives of BRCA1 and BRCA2 carriers were significantly higher than female relatives of non-carriers(BRCA1:RR=4.29,P<0.001 and RR=21.95,P<0.001;BRCA2:RR=4.19,P<0.001 and RR=4.65,P<0.001,respectively).Additionally,higher risks of pancreatic and prostate cancers were noted in male relatives of BRCA2 carriers than non-carriers(RR=4.34,P=0.001 and RR=4.86,P=0.001,respectively).Conclusions:Female relatives of BRCA1 and BRCA2 carriers are at increased risk for breast and ovarian cancers,and male relatives of BRCA2 carriers are at increased risk for pancreatic and prostate cancers.

Expression of telomerase gene and apoptosis related genes in benign and malignant breast lesion

Objective:To analyse the expression of telomerase and apoptosis related protein,and explore the possible mechanism of breast cancer development.Methods:Immunohistochemistry method(SP)was used to detect the expression of hTERT,p53 and bcl-2 in the tissues of 48 cases of human breast cancer and 42 cases of benign lesions in breast.Results: The positive rates of expression of hTERT,p53 and bcl-2 in breast cancer were 87.50%,56.25%and 54.17%,respectively. Compared with the groups of adjacent noncancerous and benign lesions,there was a significant difference among three types of tissues(P<0.05).The positive rates of expression of p53 and bcl-2 in the group with positive expression of hTERT were 64.28%and 61.90%,respectively,and their difference was significant compared with the negative group(P<0.05). Conclusion:There is a correlation between the activation of telomerases and p53 gene mutation in the development of breast cancer,and they are perhaps relation to the down regulation of bcl-2.

Incidence,mortality and survival of female breast cancer during 2003-2011 in Jiangsu province,China

Objective： To assess the incidence, mortality and survival status of female breast cancer in Jiangsu province of China. Methods： Population-based cancer registry data in Jiangsu province were collected during 2003-2011. Crude rates, age-specific rates, age-standardized rates and annual percent changes of incidence and mortality were calculated to describe the epidemiologic characteristics and time trends. Patients diagnosed from 2003 to 2005 were chosen for analyzing the survival status of breast cancer. Results： From 2003 to 2011, 17,605 females were diagnosed with breast cancer and 4,883 died in selected registry areas in Jiangsu province. The crude incidence rate was 25.18/100,000, and the age-standardized rates by Chinese population （ASRC） and by world population （ASRW） were 19.03/100,000 and 17.92/100,000, respectively. During the same period, the crude mortality rate was 6.98/100,000 and the ASRC and ASRW were 4.93/100,000 and 4.80/100,000, respectively. From 2003 to 2011, the incidence and mortality increased with annual percent change of 11.37% and 5.78%, respectively. For survival analysis, 1,392 patients in 7 areas were identified in 2003-2005 and finished 5 years of follow-up. Survival rates were found to decrease with survival years, the 5-year observed survival rate was 45.9% and the relative survival rate was 52.0%. We also found that the survival rate varied across the province, which was lower in the north and higher in the south of Jiangsu province. Conclusions： Breast cancer has become a significant public health problem in Jiangsu province and China. More resources should be invested in primary prevention, earlier diagnosis and better health services in order to increase survival rates among Chinese females.

Activation of Rac1-PI3K/Akt is required for epidermal growth factorinduced PAK1 activation and cell migration in MDA-MB-231 breast cancer cells

Epidermal growth factor （EGF） may increase cell motility, an event implicated in cancer cell invasion and metastasis. However, the underlying mechanisms for EGF-induced cell motility remain elusive. In this study, we found that EGF treatment could activate Ras-related C3 botulinum toxin substrate 1 （Racl）, PI3K/Akt and p21- actived kinase （PAK1） along with cell migration. Ectopic expression of PAK1 K299R, a dominant negative PAK1 mutant, could largely abolish EGF-induced cell migration. Blocking PI3K/Akt signalling with LY294002 or Akt siRNA remarkably inhibited both EGF-induced PAK1 activation and cell migration. Furthermore, expression of dominant-negative Racl （T17N） could largely block EGF-induced PI3K/Akt-PAK1 activation and cell migration. Interestingly, EGF could induce a significant production of ROS, and N-acetyl-L-cysteine, a scavenger of ROS which abolished the EGF-induced ROS generation, cell migration, as well as activation of PI3K/Akt and PAK, but not Racl. Our study demonstrated that EGF-induced cell migration involves a cascade of signalling events, including activation of Racl, generation of ROS and subsequent activation of PI3K/Akt and PAK1.

Long-term Efficacy and Safety of Pamidronate Disodium in Treatment of Bone Metastases in Breast Cancer

Objective： To evaluate the long-term efficacy and safety of pamidronate disodium in patients with bone lesions secondary to advanced breast carcinoma. Methods： A retrospective chart review was conducted of 62 patients receiving intravenous pamidronate disodium for metastatic breast cancer. The proportion of patients experiencing at least one skeletal related event （SRE） after 12 months of therapy was determined. Results： The proportion of patients who had an SRE was 29.00% （18 individuals） and the median time to first event was greater than 350 days. Radiotherapy（ll individuals）and pathologic fracture（6 individuals）were the most frequent type of SRE, while cord compression（1 individuals） and hypercalcaemia（0 individuals） were rare. A total of 37 individuals had transient hypocalcaemia without any clinical symptom. No significant creatinine abnormalities were encountered. There were no clinically relevant changes of calcium ,phosphate and creatinine before and after therapy. Conclusion： Long-term treatment with pamidronate disodium significantly reduces and delays skeletal morbidity from osteolytic metastases . Prolonged therapy was well tolerated. This study suggests that the rate of clinically relevant SREs is substantially lower than the event rate observed in phase llI clinical trials.

Targeting androgen receptor and trail： a novel treatment paradigm for breast cancer

OBJECTIVE TNF-related apoptosis-inducing ligand(TRAIL)is a promising cancer therapeutic agent due to its minimal toxicity to normal tissues and remarkable apoptotic activity in tumors.However,most breast cancer cells are resistant to TRAIL-induced apoptosis.Our objectives are to investigate the underlying molecular mechanisms and to develop strategies to overcome such resistance.METHODS To identify modulators of TRAIL-induced apoptosis,we carried out a genome wide si RNA screen.To validate the screening result,we either silenced or overexpressed the identified genes in various breast cancer cells and changes in growth and TRAIL-induced cell apoptosis were determined in vitro and in an orthotopic xenograft mouse model.Finally,we investigated whether small molecules targeting the identified genes improve the effectiveness of TRAIL-therapy.RESULTS We unexpectedly identified androgen receptor(AR)to be responsible for TRAIL resistance.While AR is classically viewed as the key factor in prostate cancer progression,we found that AR expression levels were markedly elevated in human invasive breast cancer specimens including triple-negative breast cancers(TNBC)that are highly aggressive with poor prognosis.Importantly,breast cancer cell lines express different levels of AR that correlated with their TRAIL resistance.AR overexpression in MDA-MB-231 and MDA-MB-436 cells suppressed the TRAIL sensitivity whereas knockdown of AR rendered MCF-7 and MDA-MB-453 cells sensitive to TRAIL-induced apoptosis.AR overexpression also induced TRAIL resistance in breast tumors in vivo.Further,we observed an upregulation of the TRAIL receptor,death receptor 5(DR5)in breast cancer cells,following the removal or inhibition of AR by its antagonists Casodex and MDV3100.Treatment with AR antagonists also enhanced TRAIL-induced breast cancer cell apoptosis.CONCLUSION AR signaling suppresses TRAIL-induced breast cancer cell apoptosis,in part,by suppressing DR5 expression,and a combination of AR antagonists together with TRAIL may be a novel and effective therapy for TNBC.

Cancer in Women and Its Relation to Work Systematic Review

Nowadays, cancer is one of the main worldwide causes of death and an increasing issue in public health. In the European Union, it is the first work-related cause of death. Studies about occupational risk exposure are a useful field of investigation to determine cancerous elements;special attention is paid to the relationship between cancer and work in women, who must constantly adapt to the working market and the new working fields, with their diverse degrees of exposure to risks. This revision has reviewed the bibliography gathered in Medline related to breast cancer, cervix cancer, uterus cancer, and ovarian cancer, along with their relationship with different work-related risks and types of working roles. The results have shown enough scientific evidence to suspect that work related exposition could be a plausible cause of these gynaecological cancers. Therefore, we want to stress the need of enhancing the coordinated investigation between all the medical specialties involved, and to encourage the spread of the necessary knowledge to manage and prevent them.

The prognostic genes of breast cancer and clinical significance

Breast cancer is one of the most frequent malignant tumors and is receiving more attention due to the increasing incidence and detection rate.Further studies regarding prognosis genes for biology are being conducted.The paper aims to review the prognostic indexes of breast cancer such as p16,Her-2,Ki-67,MCM7.

Transcutaneous Electrical Acupoint Stimulation Combined with Warm Acupuncture for Breast Cancer Related Upper Limb Lymphedema:A Retrospective Cohort Study

Objective To observe the clinical efficacy of transcutaneous electrical acupoint stimulation(TEAS)combined with warm acupuncture in treating breast cancer associated with upper limb lymphedema(BCRL).Methods This was a retrospective cohort study using a paired control design.Fifty-two BCRL patients were assigned to the control group(27 cases)and the treatment group(25 cases).The patients in the control group were treated with lymphedema comprehensive detumescence treatment(CDT)for 4 weeks,including systematic therapy composed of manual lymphatic drainage,compression bandage,skincare,and functional exercise.The patients in the treatment group were treated with TEAS combined with warm acupuncture based on the control group methods.Each treatment lasted for 30 min and was applied twice a week for 4 weeks.The arm circumference(AC)of different positions of the affected limb and the degree of swelling of the affected limb were evaluated before the first treatment and after the last treatment.The clinical efficacy was evaluated according to the degree of edema before and after treatment.All adverse events during treatment were recorded.Results The patients’AC and the swelling feeling of the affected limb in the treatment group and the control group were both reduced compared with those before treatment.Compared with the control group,AC of the wrist joint transverse stria,the midpoint between the wrist joint transverse stria and the elbow joint transverse stria in the treatment group were significantly reduced(P<0.05).The decrease in AC diameter at the midpoint between the elbow joint transverse stria and the axillary transverse stria was the most significant(P<0.01).The swelling degree of the affected limbs in the treatment group was significantly lower than before treatment,and was significantly lower compared with the control group after treatment(P<0.01).The total effective rate was 72%in the treatment group,significantly higher than that in the control group(55.56%,P<0.05).No serious adverse events occured in either group.Conclusions TEAS combined with warm acupuncture can effectively reduce AC and swelling feeling of the affected limb in patients with BCRL.The effect is better than that of CDT therapy alone.

Leptin signaling and cancer chemoresistance:Perspectives

Obesity is a major health problem and currently is endemic around the world. Obesity is a risk factor for several different types of cancer, significantly promoting cancer incidence, progression, poor prognosis and resistance to anti-cancer therapies. The study of this resistance is critical as development of chemoresistance is a serious drawback for the successful and effective drug-based treatments of cancer. There is increasing evidence that augmented adiposity can impact on chemotherapeutic treatment of cancer and the development of resistance to these treatments, particularly through one of its signature mediators, the adipokine leptin. Leptin is a pro-inflammatory, pro-angiogenic and pro-tumorigenic adipokine that has been implicated in many cancers promoting processes such as angiogenesis, metastasis, tumorigenesis and survival/resistance to apoptosis. Several possible mechanisms that could potentially be developed by cancer cells to elicit drug resistance have been suggested in the literature. Here, we summarize and discuss the current state of the literature on the role of obesity and leptin on chemoresistance, particularly as it relates to breast and pancreatic cancers. We focus on the role of leptin and its significance in possibly driving these proposed chemoresistance mechanisms, and examine its effects on cancer cell survival signals and expansion of the cancer stem cell sub-populations.

Neurotrophic receptor tyrosine kinase family members in secretory and non-secretory breast carcinomas

BACKGROUND Breast cancer is the most common female cancer and a major cause of morbidity and mortality.Progress in breast cancer therapeutics has been attained with the introduction of targeted therapies for specific sub-sets.However,other subsets lack targeted interventions and thus there is persisting need for identification and characterization of molecular targets in order to advance breast cancer therapeutics.AIM To analyze the role of lesions in neurotrophic receptor tyrosine kinase(NTRK)genes in breast cancers.METHODS Analysis of publicly available genomic breast cancer datasets was performed for identification and characterization of cases with fusions and other molecular abnormalities involving NTRK1,NTRK2 and NTRK3 genes.RESULTS NTRK fusions are present in a small number of breast cancers at the extensive GENIE project data set which contains more than 10000 breast cancers.These cases are not identified as secretory in the database,suggesting that the histologic characterization is not always evident.In the breast cancer The Cancer Genome Atlas(TCGA)cohort the more common molecular lesion in NTRK genes is amplification of NTRK1 observed in 7.9% of breast cancers.CONCLUSION Neurotrophin receptors molecular lesions other than fusions are observed more often than fusions.However,currently available NTRK inhibitors are effective mainly for fusion lesions.Amplifications of NTRK1,being more frequent in breast cancers,could be a viable therapeutic target if inhibitors efficacious for them become available.
