This study aimed to identify the risk factors associated with CINV development in Chinese breast cancer patients receiving doxorubicin and cyclophosphamide chemotherapy.Methods: Data from 304 patients enrolled in 3 previously reported prospective antiemetic studies were included. Multivariate logistic regression models were used to predict risk factors associated with CINV occurrence. Additionally, the likelihood of treatment failure in relation to the number of risk factors in individual patients was evaluated.Results: Multivariate analysis of the entire study group revealed that obesity status (defined as body mass index/= 25.0 kg/m2) and the use of olanzapine/aprepitant- or NEPA-containing anti-emetic regimens were associated with a high likelihood, while a history of motion sickness was associated with a lower likelihood, complete response (CR), and “no nausea” in the overall phase. A history of vomiting during pregnancy was also associated with a lower likelihood of an overall CR. Patients with an increasing number of risk factors had a higher likelihood of treatment failure and shorter time to first vomiting. Those who did not achieve CR and “no nausea” in the first cycle were less likely to achieve these parameters in the subsequent cycle of chemotherapy.Conclusion: The present study confirmed previously reported risk factors for CINV in Chinese breast cancer patients receiving doxorubicin and cyclophosphamide. Further optimization of CINV control is required for patients with identifiable risk factors; olanzapine/aprepitant- or NEPA- containing prophylaxis are the preferred contemporary anti-emetics regimens for Chinese breast cancer patients undergoing doxorubicin and cyclophosphamide chemotherapy.Keywords: cytotoxic, nausea and vomiting, olanzapine, aprepitant, NEPA

Subjects: Breast lump, excision biopsy, breast cancer, FNAC, health care service., Medicine
Abstract: Background: Breast cancer is becoming more important in Asia since it affect the younger age group. Question arises whether it is safe for breast lesions to be left in-situ if all the elements in triple assessment are benign. The aim of this study is to audit all the excision biopsies of breast lumps done in the University Malaya Medical Centre (UMMC), to review the association of age with the type of pathological finding and to evaluate the rate of carcinoma in these biopsies. Methods: We conducted a retrospective study of all women who had excision biopsy of a breast lump in the University Malaya Medical Centre from January 2005 to December 2006. All patients with malignant preoperative biopsies were excluded. Results: Of 717 lesions in 664 patients, 459 (64%) were fibroadenoma, 114 (15.9%) were fibrocystic disease, 20 (2.8%) were phylloides tumour, 27 (3.8%) were papilloma, 59 (8.2%) were malignant and 38 (5.3%) were of other pathology. Of the 717 open biopsies, 449 (62.6%) had fine-needle aspiration cytology (FNAC), 31 (4.3%) had core needle biopsy (CNB), while 14 (2.0%) had both FNAC and CNB done prior to excision biopsy. 251 (35%) had neither FNAC nor CNB. The incidence of fibroadenoma decreased with increasing age and the incidence of fibrocystic changes and papilloma increased with increasing age. There was no association of age with phylloides tumour. The incidence of unexpected malignancy increased with increasing age. The incidence rates were 0.3%, 4.5%, 19.4%, 29.7% and 29.6% for the age group below 30, 30-39, 40-49, 50-59 and above 60 years of age respectively. Of the 59 malignant lesions, FNAC was performed on 47 (79.7%) and CNB on 16 (27.1%). 9 had both FNAC and CNB and 3 had neither FNAC nor CNB. Out of the 56 lesions where FNAC/CNB were done, 23 (41.1%) were reported as benign, 20 (35.7%) as suspicious, 4 (7.1%) as atypical, 5 (8.9%) as inadequate, 2 (3.6%) as equivocal and 2 (3.6%) as lymphoid lesions. Out of the 23 prior biopsies reported as benign, 22 were in the age group above 40. Conclusions: In conclusion, the rate of unexpected malignancy in open biopsies increases with age. It is recommended that all women above the age of 40 presenting with a palpable breast lump or a suspicious non-palpable abnormality on screening mammogram to have their lump excised even though the lump is benign on FNAC or CNB. However, women age of 30 to 39 should also have the lump excised in the presence of other risk factors such as family history of breast cancer

Abstract: IMPORTANCE: Rare germline genetic variants in several genes are associated with increased breast cancer (BC) risk, but their precise contributions to different disease subtypes are unclear. This information is relevant to guidelines for gene panel testing and risk prediction. OBJECTIVE: To characterize tumors associated with BC susceptibility genes in large-scale population- or hospital-based studies. DESIGN, SETTING, AND PARTICIPANTS: The multicenter, international case-control analysis of the BRIDGES study included 42 680 patients and 46 387 control participants, comprising women aged 18 to 79 years who were sampled independently of family history from 38 studies. Studies were conducted between 1991 and 2016. Sequencing and analysis took place between 2016 and 2021. EXPOSURES: Protein-truncating variants and likely pathogenic missense variants in ATM, BARD1, BRCA1, BRCA2, CHEK2, PALB2, RAD51C, RAD51D, and TP53. MAIN OUTCOMES AND MEASURES: The intrinsic-like BC subtypes as defined by estrogen receptor, progesterone receptor, and ERBB2 (formerly known as HER2) status, and tumor grade; morphology; size; stage; lymph node involvement; subtype-specific odds ratios (ORs) for carrying protein-truncating variants and pathogenic missense variants in the 9 BC susceptibility genes. RESULTS: The mean (SD) ages at interview (control participants) and diagnosis (cases) were 55.1 (11.9) and 55.8 (10.6) years, respectively; all participants were of European or East Asian ethnicity. There was substantial heterogeneity in the distribution of intrinsic subtypes by gene. RAD51C, RAD51D, and BARD1 variants were associated mainly with triple-negative disease (OR, 6.19 [95% CI, 3.17-12.12]; OR, 6.19 [95% CI, 2.99-12.79]; and OR, 10.05 [95% CI, 5.27-19.19], respectively). CHEK2 variants were associated with all subtypes (with ORs ranging from 2.21-3.17) except for triple-negative disease. For ATM variants, the association was strongest for the hormone receptor (HR)+ERBB2- high-grade subt

Abstract: This study seeks to identify core housing bubble predictors and empirically investigate a novel model for detecting housing bubbles in Malaysia. We engender new insights based on the extraction of real-time opinions of market players about housing bubble formation and collapse. We employ a practical approach using a comprehensive survey of opinions from relevant walks of life via the survey data analysis software, SmartPLS3. Results indicate that housing demand, economic growth outlook, and buyers’ expectations positively impact the housing bubble. This study’s present housing market condition, foreign investment, and government policies are otherwise insignificant. We found that the present housing condition, government policies, and economic growth outlook do not influence the impact of housing demand, buyers’ expectations, and foreign investment on the housing bubble. We employed a cross-sectional research design in this study to obtain our findings. This might have indirectly suppressed more robust findings, which may have been otherwise obtained in the case of a longitudinal study. We advocate that policymakers should not overlook the significant roles of housing demand, economic growth outlook, and buyers’ expectations of the housing bubble. We show that the present housing market condition has no significant moderating effect on the impact of buyers’ expectations, foreign investment, and housing demand on housing bubbles.

Abstract: The vast majority of studies assessing communication of BRCA1/2 results with relatives and family uptake of BRCA1/2 testing have been conducted in Western societies, and a dearth of studies have been conducted in Asia among relatives of diverse carriers of pathogenic BRCA1/2 germline variants. This study aimed to present rates of BRCA1/2 result disclosure by probands and probands’ motivators and barriers of family communication and predictive testing uptake among eligible relatives. It also examined patterns of disclosure and testing uptake among different types of relatives. Eighty-seven carriers with either breast or ovarian cancer, who had previously been found to be carriers of a pathogenic variant in BRCA1/2, were interviewed over the phone using a semi-structured interview guide. Fifty-six percent of patients were Chinese, 21% were Indian, and 23% were Malay. It was found that 62.0% of eligible first- and second-degree relatives were informed by the proband about the testing result and that 11.5% of eligible first- and second-degree relatives had genetic testing. First-degree relatives were more likely to have been informed and tested compared to second-degree relatives, as were sisters compared to brothers. The low rates of family communication and testing uptake documented in this study suggest that interventions should focus on encouraging probands to inform male and second-degree relatives and targeting such relatives to increase informed decisions and accessibility to testing. Promotion strategies should be culturally sensitive to optimize outcomes.

Abstract: PURPOSE: To estimate age-specific relative and absolute cancer risks of breast cancer and to estimate risks of ovarian, pancreatic, male breast, prostate, and colorectal cancers associated with germline PALB2 pathogenic variants (PVs) because these risks have not been extensively characterized. METHODS: We analyzed data from 524 families with PALB2 PVs from 21 countries. Complex segregation analysis was used to estimate relative risks (RRs; relative to country-specific population incidences) and absolute risks of cancers. The models allowed for residual familial aggregation of breast and ovarian cancer and were adjusted for the family-specific ascertainment schemes. RESULTS: We found associations between PALB2 PVs and risk of female breast cancer (RR, 7.18; 95% CI, 5.82 to 8.85; P = 6.5 × 10-76), ovarian cancer (RR, 2.91; 95% CI, 1.40 to 6.04; P = 4.1 × 10-3), pancreatic cancer (RR, 2.37; 95% CI, 1.24 to 4.50; P = 8.7 × 10-3), and male breast cancer (RR, 7.34; 95% CI, 1.28 to 42.18; P = 2.6 × 10-2). There was no evidence for increased risks of prostate or colorectal cancer. The breast cancer RRs declined with age (P for trend = 2.0 × 10-3). After adjusting for family ascertainment, breast cancer risk estimates on the basis of multiple case families were similar to the estimates from families ascertained through population-based studies (P for difference = .41). On the basis of the combined data, the estimated risks to age 80 years were 53% (95% CI, 44% to 63%) for female breast cancer, 5% (95% CI, 2% to 10%) for ovarian cancer, 2%-3% (95% CI females, 1% to 4%; 95% CI males, 2% to 5%) for pancreatic cancer, and 1% (95% CI, 0.2% to 5%) for male breast cancer. CONCLUSION: These results confirm PALB2 as a major breast cancer susceptibility gene and establish substantial associations between germline PALB2 PVs and ovarian, pancreatic, and male breast cancers. These findings will facilitate incorporation of PALB2 into risk prediction models and optimize the clinical cance

Abstract: Abstract Signatures of immune dysregulation as clinical biomarker for psychosis have remained unclear. We aimed to compare the Neutrophil-to-lymphocyte ratio (NLR) of patients with acute non-affective first-episode psychosis (FEP) with healthy controls after accounting for emotional states. We also explored the associations of NLR with symptom severity, onset profile and cognitive functions. The NLR was enumerated from complete blood count taken within a week of assessment. All FEP patients were rated on the Positive and Negative Syndrome Scale (PANSS) and the Clinician Global Impression-Severity (CGI-S) with verbal memory and executive functions assessed with the Cambridge Neuropsychological Test Automated Battery. Prevailing emotional state was measured with Beck Depression Inventory-II and Beck Anxiety Inventory. Out of seventy-nine consecutive FEP patients presenting to the study site, twenty-seven subjects were eligible and recruited. Twenty-seven age-/sex-matched controls were recruited. FEP patients had an NLR of 1.886 over the controls after accounting for scores on emotional states. The NLR of FEP patients was positively associated with CGI-S scores, PANSS positive symptom, disorganization and excitation scores. There was no significant correlation between NLR with the duration of untreated psychosis and cognitive performances. These findings support using NLR as a clinical biomarker in FEP, purporting further prospective study to measure NLR changes in the course of treatment.

Abstract: BACKGROUND: Previous studies have shown that reproductive factors are differentially associated with breast cancer (BC) risk by subtypes. The aim of this study was to investigate associations between reproductive factors and BC subtypes, and whether these vary by age at diagnosis. METHODS: We used pooled data on tumor markers (estrogen and progesterone receptor, human epidermal growth factor receptor-2 (HER2)) and reproductive risk factors (parity, age at first full-time pregnancy (FFTP) and age at menarche) from 28,095 patients with invasive BC from 34 studies participating in the Breast Cancer Association Consortium (BCAC). In a case-only analysis, we used logistic regression to assess associations between reproductive factors and BC subtype compared to luminal A tumors as a reference. The interaction between age and parity in BC subtype risk was also tested, across all ages and, because age was modeled non-linearly, specifically at ages 35, 55 and 75 years. RESULTS: Parous women were more likely to be diagnosed with triple negative BC (TNBC) than with luminal A BC, irrespective of age (OR for parity = 1.38, 95% CI 1.16-1.65, p = 0.0004; p for interaction with age = 0.076). Parous women were also more likely to be diagnosed with luminal and non-luminal HER2-like BCs and this effect was slightly more pronounced at an early age (p for interaction with age = 0.037 and 0.030, respectively). For instance, women diagnosed at age 35 were 1.48 (CI 1.01-2.16) more likely to have luminal HER2-like BC than luminal A BC, while this association was not significant at age 75 (OR = 0.72, CI 0.45-1.14). While age at menarche was not significantly associated with BC subtype, increasing age at FFTP was non-linearly associated with TNBC relative to luminal A BC. An age at FFTP of 25 versus 20 years lowered the risk for TNBC (OR = 0.78, CI 0.70-0.88, p < 0.0001), but this effect was not apparent at a later FFTP. CONCLUSIONS: Our main findings suggest that parity is associated with TN

13. The Malay Version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ C30): Reliability and Validity Study

Author: Yusoff, N, Low, WY, and Yip, CH
Subjects: Internal consistency, Discriminant validity, lcsh:R5-920, Breast cancer, lcsh:Medicine (General), humanities, EORTC malay version, Intraclass correlation coefficient
Abstract: The Malay Version of EORTC-QLQ C30 was validated among Malaysian women who had undergone breast cancer surgery. Materials and Methods: Test-retest evaluation (i.e. three weeks and ten weeks following surgery) was carried out to examine the validity and reliability of the scale. The Cronbach’s alpha value was used to determine the internal consistency, meanwhile, test-retest Intraclass Correlation Coefficients (ICC) indicates the reliability of the scale. Effect Size Index and Mean Differences interpret the sensitivity of the scale. Discriminant validity was evaluated by comparing two groups i.e. women who had mastectomy and women who had lumpectomy. Results: Internal consistencies are acceptable for Global Health Status (0.91), Functional domains (ranging from 0.50-0.89) and Symptomatology domains (ranging from 0.75-0.99). Intraclass Correlation Coefficient (ICC) ranged from 0.05 to 0.99 for Global Health Status and Functional domains, and ranged from 0.13 to 1.00 for Symptomatology domains. Sensitivity of the scale was observed in nearly all of the domains. Conclusion: The Malay Version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ C30) is a suitable tool to measure the quality of life of women with breast cancer.

Abstract: Evidence suggests that breast cancer is taking the form of a chronicillness. This will add on to the present burden of managing chronic diseases in the healthcare delivery system. The burden of breast cancer being a chronic illness, calls for greater efforts to address the many neglected, physical-psycho-social and occupational functioning consequences. Timely efforts are needed to identify and implement interventions that are aim at improving the quality of life of women withbreast cancer. At present, research evidence is highlighting that chronic diseases may best be managed using a self-management approach, and best treated by a balance of traditional medical care and the day-to-day practice of self-management skills. This paper presents the perspective of breast cancer as a chronic illness and its implicationfor rehabilitation and medical education. It is imperative that health professionals be made aware of these survivorship issues through medical education. The goals are to reduce the many disability risks, encourage patient-health provider communication and enhance partnership in care, within a timely, holistic therapeutic program toimprove the quality of life of women with breast cancer.

Abstract: Genome-wide association studies have found SNPs at 17q22 to be associated with breast cancer risk. To identify potential causal variants related to breast cancer risk, we performed a high resolution fine-mapping analysis that involved genotyping 517 SNPs using a custom Illumina iSelect array (iCOGS) followed by imputation of genotypes for 3,134 SNPs in more than 89,000 participants of European ancestry from the Breast Cancer Association Consortium (BCAC). We identified 28 highly correlated common variants, in a 53 Kb region spanning two introns of the STXBP4 gene, that are strong candidates for driving breast cancer risk (lead SNP rs2787486 (OR = 0.92; CI 0.90-0.94; P = 8.96 × 10(-15))) and are correlated with two previously reported risk-associated variants at this locus, SNPs rs6504950 (OR = 0.94, P = 2.04 × 10(-09), r(2) = 0.73 with lead SNP) and rs1156287 (OR = 0.93, P = 3.41 × 10(-11), r(2) = 0.83 with lead SNP). Analyses indicate only one causal SNP in the region and several enhancer elements targeting STXBP4 are located within the 53 kb association signal. Expression studies in breast tumor tissues found SNP rs2787486 to be associated with increased STXBP4 expression, suggesting this may be a target gene of this locus.

Abstract: Previous genome-wide association studies among women of European ancestry identified two independent breast cancer susceptibility loci represented by single nucleotide polymorphisms (SNPs) rs13281615 and rs11780156 at 8q24. A fine-mapping study across 2.06 Mb (chr8:127,561,724-129,624,067, hg19) in 55,540 breast cancer cases and 51,168 controls within the Breast Cancer Association Consortium was conducted. Three additional independent association signals in women of European ancestry, represented by rs35961416 (OR = 0.95, 95% CI = 0.93-0.97, conditional p = 5.8 × 10(-6) ), rs7815245 (OR = 0.94, 95% CI = 0.91-0.96, conditional p = 1.1 × 10(-6) ) and rs2033101 (OR = 1.05, 95% CI = 1.02-1.07, conditional p = 1.1 × 10(-4) ) were found. Integrative analysis using functional genomic data from the Roadmap Epigenomics, the Encyclopedia of DNA Elements project, the Cancer Genome Atlas and other public resources implied that SNPs rs7815245 in Signal 3, and rs1121948 in Signal 5 (in linkage disequilibrium with rs11780156, r(2) = 0.77), were putatively functional variants for two of the five independent association signals. The results highlighted multiple 8q24 variants associated with breast cancer susceptibility in women of European ancestry.

Abstract: Candidate variant association studies have been largely unsuccessful in identifying common breast cancer susceptibility variants, although most studies have been underpowered to detect associations of a realistic magnitude. We assessed 41 common non-synonymous single-nucleotide polymorphisms (nsSNPs) for which evidence of association with breast cancer risk had been previously reported. Case-control data were combined from 38 studies of white European women (46 450 cases and 42 600 controls) and analyzed using unconditional logistic regression. Strong evidence of association was observed for three nsSNPs: ATXN7-K264R at 3p21 [rs1053338, per allele OR = 1.07, 95% confidence interval (CI) = 1.04-1.10, P = 2.9 x 10 26], AKAP9-M463I at 7q21 (rs6964587, OR = 1.05, 95% CI = 1.03-1.07, P = 1.7 x 10(-6)) and NEK10-L513S at 3p24 (rs10510592, OR = 1.10, 95% CI = 1.07-1.12, P = 5.1 x 10(-17)). The first two associations reached genome-wide statistical significance in a combined analysis of available data, including independent data from nine genome-wide association studies (GWASs): for ATXN7-K264R, OR = 1.07 (95% CI = 1.05-1.10, P = 1.0 x 10(-8)); for AKAP9-M463I, OR = 1.05 (95% CI = 1.04-1.07, P = 2.0 x 10(-10)). Further analysis of other common variants in these two regions suggested that intronic SNPs nearby are more strongly associated with disease risk. We have thus identified a novel susceptibility locus at 3p21, and confirmed previous suggestive evidence that rs6964587 at 7q21 is associated with risk. The third locus, rs10510592, is located in an established breast cancer susceptibility region; the association was substantially attenuated after adjustment for the known GWAS hit. Thus, each of the associated nsSNPs is likely to be a marker for another, non-coding, variant causally related to breast cancer risk. Further fine-mapping and functional studies are required to identify the underlying risk-modifying variants and the genes through which they act.

Abstract: The main purpose was to assess preschool teachers’ peer leadership readiness in mobilizing ‘Fly with virtual Peer-Led Fun Innovative Inquiry’ (Fly with v-PeLFII) whilst validating the effectiveness of ‘Fly with virtual Peer-Led Fun Innovative Inquiry Model’ (Fly with v-PeLFII Model). The 3-point likert scale survey instrument which consists of seven constructs were gathered from 35 preschool teachers who attended the ‘Fly with v-PeLFII 21’ virtual workshop. Comparative analysis of Pre-Test and Post-Test of ‘Fly with v-PeLFII Model’ and descriptive statistics were utilized to analyze the data. The increased percentage from Pre-Test to Post-Test within the range of 57.14 percent to 71.43 percent revealed that 35 preschool teachers from Perak are ready to lead their peer teachers in mobilizing fun innovative inquiry in the new horizon. The result also portrayed that the newly developed ‘Fly with v-PeLFII Model’ was an effective online fun innovative inquiry approach to enhance Malaysian preschool teachers’ peer leadership competency in mobilizing the ‘Fly with v-PeLFII Model’, as well as transforming new ways of delivering interesting and enjoyable instructions in the new horizon. It was also revealed that the combination of various fun innovative inquiry led to various enjoyable hands-on learning activities via virtual and non-virtual interaction platforms. ‘Fly with v-PeLFII Model’ is also subjected for further validation and assessment locally and globally.

Abstract: BACKGROUND: A recent association study identified a common variant (rs9790517) at 4q24 to be associated with breast cancer risk. Independent association signals and potential functional variants in this locus have not been explored. METHODS: We conducted a fine-mapping analysis in 55,540 breast cancer cases and 51,168 controls from the Breast Cancer Association Consortium. RESULTS: Conditional analyses identified two independent association signals among women of European ancestry, represented by rs9790517 [conditional P = 2.51 × 10(-4); OR, 1.04; 95% confidence interval (CI), 1.02-1.07] and rs77928427 (P = 1.86 × 10(-4); OR, 1.04; 95% CI, 1.02-1.07). Functional annotation using data from the Encyclopedia of DNA Elements (ENCODE) project revealed two putative functional variants, rs62331150 and rs73838678 in linkage disequilibrium (LD) with rs9790517 (r(2) ≥ 0.90) residing in the active promoter or enhancer, respectively, of the nearest gene, TET2. Both variants are located in DNase I hypersensitivity and transcription factor-binding sites. Using data from both The Cancer Genome Atlas (TCGA) and Molecular Taxonomy of Breast Cancer International Consortium (METABRIC), we showed that rs62331150 was associated with level of expression of TET2 in breast normal and tumor tissue. CONCLUSION: Our study identified two independent association signals at 4q24 in relation to breast cancer risk and suggested that observed association in this locus may be mediated through the regulation of TET2. IMPACT: Fine-mapping study with large sample size warranted for identification of independent loci for breast cancer risk.

Abstract: Genome-wide association studies (GWAS) and large-scale replication studies have identified common variants in 79 loci associated with breast cancer, explaining ∼14% of the familial risk of the disease. To identify new susceptibility loci, we performed a meta-analysis of 11 GWAS, comprising 15,748 breast cancer cases and 18,084 controls together with 46,785 cases and 42,892 controls from 41 studies genotyped on a 211,155-marker custom array (iCOGS). Analyses were restricted to women of European ancestry. We generated genotypes for more than 11 million SNPs by imputation using the 1000 Genomes Project reference panel, and we identified 15 new loci associated with breast cancer at P < 5 × 10(-8). Combining association analysis with ChIP-seq chromatin binding data in mammary cell lines and ChIA-PET chromatin interaction data from ENCODE, we identified likely target genes in two regions: SETBP1 at 18q12.3 and RNF115 and PDZK1 at 1q21.1. One association appears to be driven by an amino acid substitution encoded in EXO1.

Abstract: INTRODUCTION: Tumor lymphocyte infiltration is associated with clinical response to chemotherapy in estrogen receptor (ER) negative breast cancer. To identify variants in immunosuppressive pathway genes associated with prognosis after adjuvant chemotherapy for ER-negative patients, we studied stage I-III invasive breast cancer patients of European ancestry, including 9,334 ER-positive (3,151 treated with chemotherapy) and 2,334 ER-negative patients (1,499 treated with chemotherapy). METHODS: We pooled data from sixteen studies from the Breast Cancer Association Consortium (BCAC), and employed two independent studies for replications. Overall 3,610 single nucleotide polymorphisms (SNPs) in 133 genes were genotyped as part of the Collaborative Oncological Gene-environment Study, in which phenotype and clinical data were collected and harmonized. Multivariable Cox proportional hazard regression was used to assess genetic associations with overall survival (OS) and breast cancer-specific survival (BCSS). Heterogeneity according to chemotherapy or ER status was evaluated with the log-likelihood ratio test. RESULTS: Three independent SNPs in TGFBR2 and IL12B were associated with OS (P <10⁻³) solely in ER-negative patients after chemotherapy (267 events). Poorer OS associated with TGFBR2 rs1367610 (G > C) (per allele hazard ratio (HR) 1.54 (95% confidence interval (CI) 1.22 to 1.95), P = 3.08 × 10⁻⁴) was not found in ER-negative patients without chemotherapy or ER-positive patients with chemotherapy (P for interaction <10-3). Two SNPs in IL12B (r² = 0.20) showed different associations with ER-negative disease after chemotherapy: rs2546892 (G > A) with poorer OS (HR 1.50 (95% CI 1.21 to 1.86), P = 1.81 × 10⁻⁴), and rs2853694 (A > C) with improved OS (HR 0.73 (95% CI 0.61 to 0.87), P = 3.67 × 10⁻⁴). Similar associations were observed with BCSS. Association with TGFBR2 rs1367610 but not IL12B variants replicated using BCAC Asian samples and the independent Prospective Study o

Abstract: Genome-wide association studies (GWASs) have revealed SNP rs889312 on 5q11.2 to be associated with breast cancer risk in women of European ancestry. In an attempt to identify the biologically relevant variants, we analyzed 909 genetic variants across 5q11.2 in 103,991 breast cancer individuals and control individuals from 52 studies in the Breast Cancer Association Consortium. Multiple logistic regression analyses identified three independent risk signals: the strongest associations were with 15 correlated variants (iCHAV1), where the minor allele of the best candidate, rs62355902, associated with significantly increased risks of both estrogen-receptor-positive (ER-: odds ratio [OR] = 1.24, 95% confidence interval [CI] = 1.21-1.27, p(trend) = 5.7 3 10(-44)) and estrogen-receptor-negative (ER-: OR = 1.10, 95% CI = 1.05-1.15, p(trend) = 3.0 x 10(-4)) tumors. After adjustment for rs62355902, we found evidence of association of a further 173 variants (iCHAV2) containing three subsets with a range of effects (the strongest was rs113317823 [p(cond) = 1.61 x 10(-5)]) and five variants composing iCHAV3 (lead rs11949391; ER-: OR = 0.90, 95% CI = 0.87-0.93, p(cond) = 1.4 x 10(-4)). Twenty-six percent of the prioritized candidate variants coincided with four putative regulatory elements that interact with the MAP3K1 promoter through chromatin looping and affect MAP3K1 promoter activity. Functional analysis indicated that the cancer risk alleles of four candidates (rs74345699 and rs62355900 [iCHAV1], rs16886397 [iCHAV2a], and rs17432750 [iCHAV3]) increased MAP3K1 transcriptional activity. Chromatin immunoprecipitation analysis revealed diminished GATA3 binding to the minor (cancer-protective) allele of rs17432750, indicating a mechanism for its action. We propose that the cancer risk alleles act to increase MAP3K1 expression in vivo and might promote breast cancer cell survival.

Abstract: Large population-based registry studies have shown that breast cancer prognosis is inherited. Here we analyse single-nucleotide polymorphisms (SNPs) of genes implicated in human immunology and inflammation as candidates for prognostic markers of breast cancer survival involving 1,804 oestrogen receptor (ER)-negative patients treated with chemotherapy (279 events) from 14 European studies in a prior large-scale genotyping experiment, which is part of the Collaborative Oncological Gene-environment Study (COGS) initiative. We carry out replication using Asian COGS samples (n=522, 53 events) and the Prospective Study of Outcomes in Sporadic versus Hereditary breast cancer (POSH) study (n=315, 108 events). Rs4458204_A near CCL20 (2q36.3) is found to be associated with breast cancer-specific death at a genome-wide significant level (n=2,641, 440 events, combined allelic hazard ratio (HR)=1.81 (1.49-2.19); P for trend=1.90 × 10(-9)). Such survival-associated variants can represent ideal targets for tailored therapeutics, and may also enhance our current prognostic prediction capabilities.

Abstract: GWAS have identified a breast cancer susceptibility locus on 2q35. Here we report the fine mapping of this locus using data from 101,943 subjects from 50 case-control studies. We genotype 276 SNPs using the 'iCOGS' genotyping array and impute genotypes for a further 1,284 using 1000 Genomes Project data. All but two, strongly correlated SNPs (rs4442975 G/T and rs6721996 G/A) are excluded as candidate causal variants at odds against >100:1. The best functional candidate, rs4442975, is associated with oestrogen receptor positive (ER+) disease with an odds ratio (OR) in Europeans of 0.85 (95% confidence interval=0.84-0.87; P=1.7 × 10(-43)) per t-allele. This SNP flanks a transcriptional enhancer that physically interacts with the promoter of IGFBP5 (encoding insulin-like growth factor-binding protein 5) and displays allele-specific gene expression, FOXA1 binding and chromatin looping. Evidence suggests that the g-allele confers increased breast cancer susceptibility through relative downregulation of IGFBP5, a gene with known roles in breast cell biology.

Abstract: INTRODUCTION: We have previously shown that a tag single nucleotide polymorphism (rs10235235), which maps to the CYP3A locus (7q22.1), was associated with a reduction in premenopausal urinary estrone glucuronide levels and a modest reduction in risk of breast cancer in women age ≤50 years. METHODS: We further investigated the association of rs10235235 with breast cancer risk in a large case control study of 47,346 cases and 47,570 controls from 52 studies participating in the Breast Cancer Association Consortium. Genotyping of rs10235235 was conducted using a custom Illumina Infinium array. Stratified analyses were conducted to determine whether this association was modified by age at diagnosis, ethnicity, age at menarche or tumor characteristics. RESULTS: We confirmed the association of rs10235235 with breast cancer risk for women of European ancestry but found no evidence that this association differed with age at diagnosis. Heterozygote and homozygote odds ratios (ORs) were OR = 0.98 (95% CI 0.94, 1.01; P = 0.2) and OR = 0.80 (95% CI 0.69, 0.93; P = 0.004), respectively (P(trend) = 0.02). There was no evidence of effect modification by tumor characteristics. rs10235235 was, however, associated with age at menarche in controls (P(trend) = 0.005) but not cases (P(trend) = 0.97). Consequently the association between rs10235235 and breast cancer risk differed according to age at menarche (P(het) = 0.02); the rare allele of rs10235235 was associated with a reduction in breast cancer risk for women who had their menarche age ≥15 years (OR(het) = 0.84, 95% CI 0.75, 0.94; OR(hom) = 0.81, 95% CI 0.51, 1.30; P(trend) = 0.002) but not for those who had their menarche age ≤11 years (OR(het) = 1.06, 95% CI 0.95, 1.19, OR(hom) = 1.07, 95% CI 0.67, 1.72; P(trend) = 0.29). CONCLUSIONS: To our knowledge rs10235235 is the first single nucleotide polymorphism to be associated with both breast cancer risk and age at menarche consistent with the well-documented association between la

Abstract: BACKGROUND: Breast cancer is one of the most common malignancies in women. Genome-wide association studies have identified FGFR2 as a breast cancer susceptibility gene. Common variation in other fibroblast growth factor (FGF) receptors might also modify risk. We tested this hypothesis by studying genotyped single-nucleotide polymorphisms (SNPs) and imputed SNPs in FGFR1, FGFR3, FGFR4 and FGFRL1 in the Breast Cancer Association Consortium. METHODS: Data were combined from 49 studies, including 53 835 cases and 50 156 controls, of which 89 050 (46 450 cases and 42 600 controls) were of European ancestry, 12 893 (6269 cases and 6624 controls) of Asian and 2048 (1116 cases and 932 controls) of African ancestry. Associations with risk of breast cancer, overall and by disease sub-type, were assessed using unconditional logistic regression. RESULTS: Little evidence of association with breast cancer risk was observed for SNPs in the FGF receptor genes. The strongest evidence in European women was for rs743682 in FGFR3; the estimated per-allele odds ratio was 1.05 (95% confidence interval=1.02-1.09, P=0.0020), which is substantially lower than that observed for SNPs in FGFR2. CONCLUSION: Our results suggest that common variants in the other FGF receptors are not associated with risk of breast cancer to the degree observed for FGFR2.

Abstract: New molecular and pharmacological tools have made it possible for us to identify the intricate network that exists between the immune system and the brain, a network that allows the two systems to signal each other continuously and rapidly. Chemicals produced by immune cells signal the brain, and the brain in turn sends chemical signals to restrain the immune system. These same chemical signals also affect behavior and the response to stress.

Abstract: Abstract Background Breast cancer is one of the most common diseases in women worldwide. Many studies have been conducted to predict the survival indicators, however most of these analyses were predominantly performed using basic statistical methods. As an alternative, this study used machine learning techniques to build models for detecting and visualising significant prognostic indicators of breast cancer survival rate. Methods A large hospital-based breast cancer dataset retrieved from the University Malaya Medical Centre, Kuala Lumpur, Malaysia (n = 8066) with diagnosis information between 1993 and 2016 was used in this study. The dataset contained 23 predictor variables and one dependent variable, which referred to the survival status of the patients (alive or dead). In determining the significant prognostic factors of breast cancer survival rate, prediction models were built using decision tree, random forest, neural networks, extreme boost, logistic regression, and support vector machine. Next, the dataset was clustered based on the receptor status of breast cancer patients identified via immunohistochemistry to perform advanced modelling using random forest. Subsequently, the important variables were ranked via variable selection methods in random forest. Finally, decision trees were built and validation was performed using survival analysis. Results In terms of both model accuracy and calibration measure, all algorithms produced close outcomes, with the lowest obtained from decision tree (accuracy = 79.8%) and the highest from random forest (accuracy = 82.7%). The important variables identified in this study were cancer stage classification, tumour size, number of total axillary lymph nodes removed, number of positive lymph nodes, types of primary treatment, and methods of diagnosis. Conclusion Interestingly the various machine learning algorithms used in this study yielded close accuracy hence these methods could be used as alternative predictive tools in the breast cancer survival studies, particularly in the Asian region. The important prognostic factors influencing survival rate of breast cancer identified in this study, which were validated by survival curves, are useful and could be translated into decision support tools in the medical domain.

Subjects: Environmental sciences, GE1-350
Abstract: Earthquake tremor from neighbouring country had caused several cases of structural and non-structural damages toward the buildings in Malaysia. This issue had raised public attention about the safeness of the low-rise, mid-rise and high-rise building in the country. Buildings without proper seismic resistance design will collapse during the earth earthquake and people who could not evacuated from the building will be buried alive. Viscous Damper is one of the passive structural control systems in attenuating the seismic response on building. The damper utilized principle of fluid flow through orifices to create friction that turns the movement into heat energy to be release into atmosphere. This study is to investigate the effectiveness and behaviour of the mechanical shock absorber as damper in resisting seismic force. Three different type of dampers are being tested under 6 different loading displacement amplitude to measure the hysteresis loops and energy dissipation capability. The results showed that the extra features of the coil over in EX5 Kriss Wave damper with 17 kNmm had significantly increase the energy dissipation capability up to 5.6 time better than the lowest 3 kNmm APIDO type damper.

Abstract: Winnie Yeo,1,2 Frankie KF Mo,1,2 Elizabeth Pang,1,2 Joyce JS Suen,1 Jane Koh,1,2 Claudia HW Yip,1 Christopher CH Yip,1 Leung Li,1 Herbert HF Loong,1,2 Giok S Liem1 1Department of Clinical Oncology, Sir YK Pao Centre for Cancer, Prince of Wales Hospital, 2Hong Kong Cancer Institute, State Key Laboratory of Oncology in South China, Faculty of Medicine, The Chinese University of Hong Kong, Shatin, Hong Kong Introduction: Understanding of quality of life (QoL) of young Chinese breast cancer patients after adjuvant cytotoxic chemotherapy is limited. This study aims to assess the QoL of premenopausal Chinese breast cancer women after receiving adjuvant chemotherapy.Patients and methods: Eligibility criteria included stage I–III breast cancer, premenopausal and age ≤45 years at cancer diagnosis and having received adjuvant chemotherapy within 3–10 years before entry to the present study. Patients’ background demographics at the time of breast cancer diagnosis, together with tumor characteristics and anticancer treatments, were collected. At the time of study entry, the menopausal status based on menstrual history, body mass index, and QoL (assessed using Functional Assessment of Cancer Therapy-Breast +4) were recorded.Results: Two hundred and eighty patients were recruited. Ninety-five patients (33.9%) underwent breast-conserving surgery, and nearly all (98.6%) underwent axillary dissection. For adjuvant therapies, 249 patients (88.9%) received anthracycline-containing chemotherapy and 79 (28.2%) received taxane-containing chemotherapy, while 68 (24.3%) received both. One hundred and eighty six patients (66.4%) received adjuvant radiotherapy, and 214 (76.4%) received adjuvant tamoxifen. The median time from breast cancer diagnosis to study entry was 5.01 years. QoL assessment at study entry revealed that older patients had worse social well-being (SWB; mean scores for age ≤40, 41–45, 46–50 and >50 years were 22.0, 19.3, 19.1 and 18.1, respectively, P=0.0442). Patients who underwent axillary dissection had worse scores for breast cancer subscale (BCS; mean score 22.2 vs. 28.3, P=0.0212). Patients who underwent taxane-containing chemotherapy had worse scores for arm subscale (mean score 13.8 vs. 15.3, P=0.0053).Conclusion: At a median follow-up of 5 years post-diagnosis, patients who were younger had fewer disturbances in their SWB. Patients who had axillary dissection had worse BCS scores, while those who received taxane had worse scores for arm subscale. Further studies are warranted for breast-specific QoL to address the specific issues encountered by breast cancer patients. Keywords: cytotoxic, QoL, FACT-B+4, cancer survivors breast, premenopausal

49. Boom-Bust Housing Price Dynamic: The Case of Malaysia

Author: Yip Chee Yin, Woo Kok Hoong, Oon Kam Hoe, Nabihah Binti Aminaddin, and Nurfadhilah Binti Abu Hasan
Subjects: stability test, cointegrating regression, mean reversion regression, bubbles, cycles, Business, HF5001-6182, Economics as a science, HB71-74
Abstract: This paper aims to differentiate housing price bubble from a housing price cycle through the investigation and analysis of the price volatility driving components using graphical analysis, cointegrating regression and mean reversion regression. The findings suggest that Malaysia is not facing any housing bubble at the point of time since there is no sharp upsurge and rapid fall of house prices. The recent upswing in house prices followed by a gradual coming down rather reflect a severe price cycle which started in 2009. The peak was observed in 2013 and since then has reversed into a continuous but gradual fall. The cycle is persisting and has not bottomed out yet. Our results show that the main reasons for the price booms are speculative herd instinct and lax in house loan lending policy before 2012. Subsequently the various anti cooling measures by the Malaysian government have helped to control price expansion.

50. Genetic variations in transcription factor 7-like 2 (TCF7L2) gene: association of TCF7L2 rs12255372(G/T) or rs7903146(C/T) with breast cancer risk and clinico-pathological parameters.

Abstract: The purpose of the present study was to evaluate the association between TCF7L2 rs12255372(G/T) or rs7903146(C/T) polymorphism and breast cancer risk, and clinico-pathologic characteristics of the patients. Genotyping of these polymorphisms was performed on 387 breast cancer patients and 252 normal and healthy women who had no history of any malignancy using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method in a hospital-based Malaysian population. The allele (P = 0.033) frequency of rs7903146 (T) polymorphism was significantly higher in the cancer patients than normal individuals. No significant association was demonstrated between CT (OR(adj) = 1.386; 95% CI, 0.985-1.949) or TT (OR(adj) = 1.579; 95% CI, 0.869-2.870) genotype and breast cancer risk. However, women who were carriers of T allele (OR(adj) = 1.316; 95% CI, 1.022-1.695) or T allele genotype (OR(adj) = 1.419; 95% CI, 1.027-1.960) showed significant increased risk of breast cancer. Women who were GT heterozygotes (OR(adj) = 1.329; 95% CI, 0.948-1.862) or TT homozygotes (OR(adj) = 1.574; 95% CI, 0.829-2.987), and carriers of T allele genotype (OR(adj) = 1.365; 95% CI, 0.989-1.883) or T allele (OR(adj) = 1.284; 95% CI, 0.995-1.657) were not associated with breast cancer risk. The rs7903146(T) allele genotype was significantly associated with nodal involvement (P = 0.003) but rs12255372 (T) allele genotype was not associated with the clinico-pathologic characteristics. In conclusion, our findings suggest that rs7903146 (T) variant may elevate the risk of breast cancer, thus could be a potential candidate for breast cancer susceptibility. The variant may also increase the metastatic potential of the tumor. [ABSTRACT FROM AUTHOR]
