Abstract
Hierarchical classification offers a more specific categorization of data and breaks down large classification problems into subproblems, providing improved prediction accuracy and predictive power for undefined categories, while also mitigating the impact of poor-quality data. Despite these advantages, its application in predicting primary cancer is rare. To leverage the similarity of cancers and the specificity of methylation patterns among them, we developed the Cancer Hierarchy Classification Tool (CHCT) using the idea of hierarchical classification, with methylation data from 30 cancer types and 8239 methylome samples downloaded from publicly available databases (The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO)). We used unsupervised clustering to divide the classification subproblems and screened differentially methylated sites using Analysis of variance (ANOVA) test, Tukey-kramer test, and Boruta algorithms to construct models for each classifier module. After validation, CHCT accurately classified 1568 out of 1660 cases in the test set, with an average accuracy of 94.46%. We further curated an independent validation cohort of 677 cancer samples from GEO and assigned a diagnosis using CHCT, which showed high diagnostic potential with generally high accuracies (an average accuracy of 91.40%). Moreover, CHCT demonstrates predictive capability for additional cancer types beyond its original classifier scope as demonstrated in the medulloblastoma and pituitary tumor datasets. In summary, CHCT can hierarchically classify primary cancer by methylation profile, by splitting a large-scale classification of 30 cancer types into ten smaller classification problems. These results indicate that cancer hierarchical classification has the potential to be an accurate and robust cancer classification method.

Breast and prostate cancer risk: The interplay of polygenic risk, rare pathogenic germline variants, and family history. Genet Med 2022; 24:576-585. [PMID: 34906469 DOI: 10.1016/j.gim.2021.11.009] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2021] [Revised: 09/12/2021] [Accepted: 11/12/2021] [Indexed: 12/22/2022] Open
Abstract
PURPOSE We aimed to investigate to what extent polygenic risk scores (PRS), rare pathogenic germline variants (PVs), and family history jointly influence breast cancer and prostate cancer risk. METHODS A total of 200,643 individuals from the UK Biobank were categorized as follows: (1) heterozygotes or nonheterozygotes for PVs in moderate to high-risk cancer genes, (2) PRS strata, and (3) with or without a family history of cancer. Multivariable logistic regression and Cox proportional hazards models were used to compute the odds ratio across groups and the cumulative incidence through life. RESULTS Cumulative incidence by age 70 years among the nonheterozygotes across PRS strata ranged from 9% to 32% and from 9% to 35% for breast cancer and prostate cancer, respectively. Among the PV heterozygotes it ranged from 20% to 48% in moderate-risk genes and from 51% to 74% in high-risk genes for breast cancer, and it ranged from 30% to 59% in prostate cancer risk genes. Family history was always associated with an increased cancer odds ratio. CONCLUSION PRS alone provides a meaningful risk gradient leading to a cancer risk stratification comparable to PVs in moderate risk genes, whereas acts as a risk modifier when considering high-risk genes. Including family history along with PV and PRS further improves cancer risk stratification.

Defining the Impact of Family History on Detection of High-grade Prostate Cancer in a Large Multi-institutional Cohort. Eur Urol 2021; 82:163-169. [PMID: 34980493 PMCID: PMC9243191 DOI: 10.1016/j.eururo.2021.12.011] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Revised: 11/23/2021] [Accepted: 12/06/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND The risk of high-grade prostate cancer, given a family history of cancer, has been described in the general population, but not among men selected for prostate biopsy in an international cohort. OBJECTIVE To estimate the risk of high-grade prostate cancer on biopsy based on a family history of cancer. DESIGN, SETTING, AND PARTICIPANTS This is a multicenter study of men undergoing prostate biopsy from 2006 to 2019, including 12 sites in North America and Europe. All sites recorded first-degree prostate cancer family histories; four included more detailed data on the number of affected relatives, second-degree relatives with prostate cancer, and breast cancer family history. OUTCOMES MEASUREMENTS AND STATISTICAL ANALYSIS Multivariable logistic regressions evaluated odds of high-grade (Gleason grade group ≥2) prostate cancer. Separate models were fit for family history definitions, including first- and second-degree prostate cancer and breast cancer family histories. RESULTS AND LIMITATIONS A first-degree prostate cancer family history was available for 15 799 men, with a more detailed family history for 4617 (median age 65 yr, both cohorts). Adjusted odds of high-grade prostate cancer were 1.77 times greater (95% confidence interval [CI] 1.57-2.00, p < 0.001, risk ratio [RR] = 1.40) with first-degree prostate cancer, 1.38 (95% CI 1.07-1.77, p = 0.011, RR = 1.22) for second-degree prostate cancer, and 1.30 (95% CI 1.01-1.67, p = 0.040, RR = 1.18) for first-degree breast cancer family histories. Interaction terms revealed that the effect of a family history did not differ based on prostate-specific antigen but differed based on age. This study is limited by missing data on race and prior negative biopsy. CONCLUSIONS Men with indications for biopsy and a family history of prostate or breast cancer can be counseled that they have a moderately increased risk of high-grade prostate cancer, independent of other risk factors. PATIENT SUMMARY In a large international series of men selected for prostate biopsy, finding a high-grade prostate cancer was more likely in men with a family history of prostate or breast cancer.

Abstract
Diabetes and breast cancer are pathophysiologically similar and clinically established
diseases that co-exist with a wider complex similar molecular signalling and having a similar set of
risk factors. Insulin plays a pivotal role in the invasion and migration of breast cancer cells. Several
ethnopharmacological evidences shed light on the concomitant anti-diabetic and anti-cancer activity
of medicinal plant and phytochemicals against breast tumors of patients with diabetes. This present
article reviewed the findings on medicinal plants and phytochemicals with concomitant antidiabetic
and anti-cancer effects reported in scientific literature to facilitate the development of dual-
acting therapies against diabetes and breast cancer. The schematic tabular form of published literature
on medicinal plants (63 plants belongs to 45 families) concluded the dynamics of phytochemicals
against diabetes and breast tumors that could be explored further for the discovery of therapies
for controlling of breast cancer cell invasion and migration in patients with diabetes.

Abstract
BACKGROUND There is a lack of evidence-based recommendations for the age at which women with a family history of cancers other than breast cancer should start breast cancer screening. METHODS Using Swedish family cancer data sets, the authors conducted a nationwide cohort study including 5,099,172 Swedish women born after 1931 (follow-up, 1958-2015). Accounting for calendar time, they calculated the relative risk of breast cancer for women with a family history of a discordant cancer in 1 first-degree relative. Furthermore, the authors used 10-year cumulative risk to determine the ages at which women with a family history of discordant cancer reached risk thresholds at which women in the general population were recommended to start breast cancer screening. RESULTS A family history of cancer at 15 sites was associated with an increased risk of breast cancer. Among women younger than 50 years, the highest risk of breast cancer was observed for those with a family history of ovarian cancer (standardized incidence ratio, 1.44; 95% confidence interval, 1.26-1.64). In these women, the risk of breast cancer associated with a family history at other cancer sites ranged from 1.08-fold for prostate cancer to 1.18-fold for liver cancer. When breast cancer screening was recommended to be started at the age of 50 years for the general population, women with 1 first-degree relative with ovarian cancer attained the threshold risk for screening at the age of 46 years. Women with a family history of other discordant cancers did not reach the risk thresholds for screening at younger ages. CONCLUSIONS Many cancers showed familial associations with breast cancer, but women with a family history of these cancers (except for ovarian cancer) did not reach risk thresholds for screening at younger ages.

Abstract
ABSTRACT The evidence for associations between family history of prostate cancer and the risk of breast cancer and ovarian cancer is inconclusive. The first systematic review and meta-analysis of studies was conducted to assess the risk of breast cancer and ovarian cancer associated with a family history of prostate cancer.A literature search was conducted using MEDLINE, Embase and Web of science databases up to January 31, 2019. Data were screened and extracted independently by 2 reviewers. The pooled risk ratio (RR) and its 95% confidence interval (CI) were calculated using random-effects models. The GRADE approach was used to assess the quality of evidence.Nine observational studies including 8,011,625 individuals were included in the meta-analysis. The meta-analysis showed that family history of prostate cancer in first-degree relatives was associated with an increased risk of breast cancer (RR 1.12, 95%CI 1.09 to 1.14) with moderate quality evidence, subgroup analysis showed consistent results. Compared with no family history of prostate cancer, history of prostate cancer in first-degree relatives was associated with a slight risk of ovarian cancer (1.10, 95%CI 1.01 to 1.20) with moderate quality evidence. Family history of prostate cancer among sibling was associated with a 17% increased risk of ovarian cancer (95% CI 1.03 to 1.34), however, no significant association was found between family history of prostate cancer among parent and risk of ovarian cancer (RR 1.19, 95% CI 0.84 to 1.70).This review demonstrates that women with a family history of prostate cancer in first-degree relatives was associated with an increased risk of breast cancer and ovarian cancer. These findings may aid in screening, earlier detection and treatment of women with a family history of prostate cancer in first-degree relatives.

Patterns of cancer family history and genetic counseling eligibility among African Americans with breast, prostate, lung, and colorectal cancers: A Detroit Research on Cancer Survivors cohort study. Cancer 2020; 126:4744-4752.

Abstract
BACKGROUND Family history (FH) remains one of the strongest risk factors for many common cancers and is used to determine cancer genetic counseling (CGC) eligibility, but the understanding of familial cancer patterns in African Americans is limited. METHODS This study evaluated cancer FH among African Americans with invasive breast cancer, prostate cancer, lung cancer, or colorectal cancer (CRC) in the Detroit Research on Cancer Survivors (ROCS) cohort. Associations between participant cancer type, site-specific FH, and meeting national guidelines for CGC were evaluated via logistic regression. Cancer FH patterns were evaluating via hierarchical clustering. RESULTS Among 1500 ROCS participants, 71% reported at least 1 first-degree relative or grandparent with cancer. FHs of breast cancer, CRC, lung cancer, and prostate cancer were most common among participants with the same diagnosis (odds ratio [OR] for breast cancer, 1.14; P < .001; OR for CRC, 1.08; P = .003; OR for lung cancer, 1.09; P = .008; OR for prostate cancer, 1.14; P < .001). Nearly half of the participants (47%) met national CGC guidelines, and 24.4% of these participants met CGC criteria on the basis of their cancer FH alone. FH was particularly important in determining CGC eligibility for participants with prostate cancer versus breast cancer (OR for FH vs personal history alone, 2.91; 95% confidence interval, 1.94-4.35; P < .001). In clustering analyses, breast and prostate cancer FH-defined clusters were common across all participants. Clustering of CRC and breast cancer FHs was also observed. CONCLUSIONS ROCS participants reported high rates of cancer FH. The high rate of eligibility for CGC among ROCS participants supports the need for interventions to increase referrals and uptake of CGC among African Americans.

Abstract
Aims: This study aimed to determine the expression of asparagine synthetase (ASNS) in breast cancer (BC) tissues and estimate its prognostic value for BC patients. Besides, the roles of ASNS in the proliferation of BC cells were also examined in the study. Methods: Quantitative real-time PCR was conducted to detect the expression of ASNS mRNA in BC tissues and normal controls. The relationship between ASNS expression and clinical characteristics of BC patients was analyzed using χ-square test. MTT assay was performed to explore the effect of ASNS expression on the proliferation of BC cells. Kaplan-Meier curves were plotted to describe the overall survival rate of BC patients. Cox regression analyses were implemented to investigate prognostic factors. Results: ASNS mRNA overexpression was observed in BC tissues (p < 0.05). High expression of ASNS was significantly related to histological grade (p = 0.017), vascular invasion (p = 0.009), and PR status (p = 0.014). The downregulation of ASNS affected the proliferation of BC cells (p < 0.05). Kaplan-Meier survival showed that patients with high ASNS expression lived shorter than those with low expressions (p < 0.001). Finally, Cox regression analyses revealed that ASNS could act as a prognostic marker for BC patients (p < 0.001, HR = 3.293, 95% CI = 1.790-6.058). Conclusion: Taken together, ASNS is a valuable prognostic biomarker for BC patients.

Characteristics predicting recommendation for familial breast cancer referral in a cohort of women from primary care. J Community Genet 2020; 11:331-338. [PMID: 31965555 PMCID: PMC7295867 DOI: 10.1007/s12687-020-00452-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Accepted: 01/14/2020] [Indexed: 11/03/2022] Open
Abstract
Family history of breast and related cancers can indicate increased breast cancer (BC) risk. In national familial breast cancer (FBC) guidelines, the risk is stratified to guide referral decisions. We aimed to identify characteristics associated with the recommendation for referral in a large cohort of women undergoing FBC risk assessment in a recent primary care study. Demographic, family history, psychological and behavioural factors were collected with family history questionnaires, psychological questionnaires and manual data extraction from general practice electronic health records. Participants were women aged 30–60 with no previous history of breast or ovarian cancer. Data from 1127 women were analysed with stepwise logistic regression. Two multivariable logistic models were developed to predict recommendations for referral: using the entire cohort (n = 1127) and in a subgroup with uncertain risks (n = 168). Model performance was assessed by the area under the receiver operating curve (AUC). In all 1127 women, a multivariable model incorporating five family history components (BC aged < 40, bilateral BC, prostate cancer, first degree relative with ovarian cancer, paternal family history of BC) and having a mammogram in the last 3 years, performed well (AUC = 0.86). For the 168 uncertain risk women, only paternal family history of BC remained significant (AUC = 0.71). Clinicians should pay particular attention to these five family history components when assessing FBC risk, especially prostate cancer which is not in the current national guidelines.

Abstract
INTRODUCTION In the last century, there have been major changes within the population structure in Germany. The aim of this study was to determine the impact of a changing population structure on identification of familial prostate cancer (PCa), and to investigate how many and which types of other cancers have occurred in patients and their first-degree relatives. MATERIALS AND METHODS A total of 19,540 patients were evaluated in a prospectively collected PCa family database and divided into four birth cohorts: 1925-1934 (cohort A), 1935-1944 (cohort B), 1945-1954 (cohort C), and 1955-1964 (cohort D). Other primary cancers and cancers of first-degree relatives were evaluated. RESULTS The percentage of PCa patients with ≥2 sons declined (A: 28.9% to D: 21.6%). The percentage of patients whose fathers lived for ≥65 years increased (B: 64.2% to D: 73.0%). Malignancies of the skin, the urinary tract, and the lymphoid/hematopoietic tissue were more common in patients with a positive first-degree PCa family history and their first-degree relatives. Additionally, first-degree relatives reported more often neoplasms of respiratory/intrathoracic organs and the female breast. CONCLUSIONS A small family size, an early deceased father, and a high number of sporadic cases complicate the identification of familial PCa patients. Thus, a detailed family history should also include unaffected first-degree relatives to avoid any misclassification. Findings of other primary cancers in patients and their relatives warrant further investigation.

Abstract
Several studies have made strong efforts to understand how age and parity modulate the risk of breast cancer. A holistic understanding of the dynamic regulation of the morphological, cellular, and molecular milieu of the mammary gland offers insights into the drivers of breast cancer development as well as into potential prophylactic interventions, the latter being a longstanding ambition of the research and clinical community aspiring to eradicate the disease. In this review we discuss mechanisms that react to pregnancy signals, and we delineate the nuances of pregnancy-associated dynamism that contribute towards either breast cancer development or prevention. Further definition of the molecular basis of parity and breast cancer risk may allow the elaboration of tools to predict and survey those who are at risk of breast cancer development.

Abstract
Constructing disease-disease similarity network is important in elucidating the associations between the origin and molecular mechanism of diseases, and in researching disease function and medical research. In this paper, we use a high-quality protein interaction network and a collection of pathway databases to construct a Human Pathway-based Disease Network (HPDN) to explore the relationship between diseases and their intrinsic interactions. We find that the similarity of two diseases has a strong correlation with the number of their shared functional pathways and the interaction between their related gene sets. Comparing HPDN with disease networks based on genes and symptoms respectively, we find the three networks have high overlap rates. Additionally, HPDN can predict new disease-disease correlations, which are supported by Comparative Toxicogenomics Database (CTD) benchmark and large-scale biomedical literature database. The comprehensive, high-quality relations between diseases based on pathways can further be applied to study important matters in systems medicine, for instance, drug repurposing. Based on a dense subgraph in our network, we find two drugs, prednisone and folic acid, may have new indications, which will provide potential directions for the treatments of complex diseases.

Abstract
PURPOSE Breast and prostate cancer co-occur in families, and women with a family history of prostate cancer are at increased breast cancer risk. Prostate cancer is among the most heritable cancers, but few studies have investigated its association with familial breast cancer. The objective of this study is to investigate the extent to which familial breast or prostate cancer in first-degree relatives increases prostate cancer risk. EXPERIMENTAL DESIGN A prospective study of 37,002 U.S. men in the Health Professionals Follow-up Study. During the 16-year follow-up to 2012, 4,208 total and 344 lethal cases were diagnosed. Using cause-specific hazards regression, we estimated the multivariable HRs and 95% confidence intervals (CI) for associations between familial breast or prostate cancer and total and lethal prostate cancer. RESULTS Those with familial breast cancer had a 21% greater risk of prostate cancer overall (95% CI, 1.10-1.34), and a 34% greater risk of lethal disease (HR 1.34; 95% CI, 0.96-1.89). Family history of prostate cancer alone was associated with a 68% increased risk of total disease (95% CI, 1.53-1.83) and a 72% increased risk of lethal disease (95% CI, 1.25-2.38). Men with a family history of both cancers were also at elevated risk. CONCLUSIONS Our study found that men with a family history of breast or prostate cancer had elevated prostate cancer risks, including risk of lethal disease. These findings have translational relevance for cancer risk prediction in men.

Abstract
BACKGROUND Peripheral arterial disease (PAD) is one of the major manifestations of general atherosclerosis and strongly associated with increased cardiovascular morbidity and mortality. Because only few epidemiologic studies are available concerning the prevalence of PAD in inhabitants ≥ 80 years of age, we screened inhabitants of nursing care homes in Germany for PAD and cardiovascular diseases and to assess the one year mortality. PATIENTS AND METHODS We conducted a prospective cohort study, screening inhabitants of 42 nursing homes for PAD. Demographic data, comorbidities, cardiovascular risk factors and daily medication were collected. PAD was defined as ankle-brachial index < 0.9. During a follow up period of one year, cardio- and cerebrovascular events and mortality were recorded, as well as the rate of falls and major amputation. RESULTS 1,329 probands (391 men, 938 women) > 60 years were eligible for further analysis. The mean age was 84.1 years (range 61-107 years) and the prevalence of PAD was 31.5 % . Media sclerosis was found in up to 17 %, and an existing diagnosis of PAD (in case of pathological ABI) and undertreatment was common. Probands with PAD were less likely to be treated according to guideline recommendations (antiplatelet therapy, beta blockers, statins) than probands with coronary artery disease (CAD). The overall one-year mortality was 19.8 % (n = 236), significantly higher than for a gender and age matched German population (p < 0.001). CONCLUSIONS The current study shows a high prevalence of PAD in German nursing care homes. The one year mortality was not significantly different between probands with PAD and those with severe PAD (defined as an ABI of ≤ 0.5), whereas a media sclerosis was associated with an increased risk in probands with CAD in comparison to those without. Use of anti-diabetic agents and aspirin in monotherapy was associated with a reduced one-year mortality risk.

Abstract
BACKGROUND Prostate cancer is the most common malignancy among the male population in the United States and the 3rd most common non-skin cancer among men in Iran. Its prevalence has shown a rising trend in recent decades. The aim of this study was to report the epidemiological features of prostate cancer in patients referred for prostate biopsy in the south of Iran and to evaluate the accuracy of the levels of the prostate-specific antigen (PSA) and the PSA-density (PSAD) as well as the extension of the disease in the prediction of the biological behavior of prostate cancer. METHODS This is a retrospective study on the medical records of 1982 consecutive patients who underwent transrectal ultrasound-guided biopsy due to an abnormal digital rectal examination and/or an elevated PSA level following referral from the Urology Ward to the Radiology Department of Shahid Faghihi Hospital in Shiraz, southern Iran, between December 2003 and July 2014. RESULTS The overall cancer detection rate was 33.1%. Although the cancer was more prevalent among the elderly patients, a significant fraction (7%) of the patients were aged < 55 years. The sensitivity and specificity of the PSA were 97.4% and 8.7% and those of the PSAD were 82.9% and 52%, respectively. Of the 637 patients with prostate cancer, 250 (39.2%) had unilateral disease, 378 (59.4%) had bilateral disease, and 9 (1.4%) had inner-gland involvement. Most of the patients with bilateral involvement had high-grade Gleason scores. CONCLUSION Our study underlines the relationship between age and the frequency of cancer; the levels of the PSA and the PSAD and the Gleason score; and the extent of tumor involvement and the grade of prostate cancer and also highlights the significance of screening, especially in younger patients.

Abstract
Introduction Familial aggregation is now well established with an increased risk of prostate cancer in patients with a family history of prostate cancer in first degree relatives. The aim of this paper was to investigate the role of family history of cancer in first degree relatives in prostate cancer risk. Results As expected, a family history of prostate cancer in first-degree relatives was more frequent in cases than in controls (OR 3.10, 95% CI 2.32-4.15). A family history of early BCa (before age 50) in first-degree relatives was more frequent in cases than in controls (OR 1.79, 95% CI 1.09-2.94) with higher risk of aggressive PCa. The association was more pronounced for BCa in daughters (OR 15.26 95% CI 1.95-120). Conclusions In summary, a family history of BCa in first degree relatives before age 50 may increases the risk of PCa with higher Gleason score. This finding could suggest a specific prostate surveillance and/or genetic counselling for men who present such familial history. Methods EPIdemiological study of Prostate CAncer (EPICAP) is a population-based case-control study specifically designed to investigate the role of environmental and genetic factors in prostate cancer. Detailed information on family history of cancer in first degree relatives (parents, brothers and sisters, children) was collected as well as the age of occurrence and the localization of each cancer. Overall, 819 cases and 879 controls have been included.

Abstract
Background Evidence suggests that risk of colorectal and prostate cancer is increased among those with a family history of the same disease, particularly among first-degree relatives. However, the aggregation of colorectal and prostate cancer within families has not been well investigated. Methods Analyses were conducted among participants of the Women’s Health Initiative (WHI) observational cohort, free of cancer at the baseline examination. Subjects were followed for colorectal cancer through August 31st, 2009. A Cox-proportional hazards regression modeling approach was used to estimate risk of colorectal cancer associated with a family history of prostate cancer, colorectal cancer and both cancers among first-degree relatives of all participants and stratified by race (African American vs. White). Results Of 75,999 eligible participants, there were 1122 colorectal cancer cases diagnosed over the study period. A family history of prostate cancer alone was not associated with an increase in colorectal cancer risk after adjustment for confounders (aHR =0.94; 95% CI =0.76, 1.15). Separate analysis examining the joint impact, a family history of both colorectal and prostate cancer was associated with an almost 50% increase in colorectal cancer risk (aHR = 1.48; 95% CI = 1.04, 2.10), but similar to those with a family history of colorectal cancer only (95% CI = 1.31; 95% CI = 1.11, 1.54). Conclusions Our findings suggest risk of colorectal cancer is increased similarly among women with colorectal cancer only and among those with both colorectal and prostate cancer diagnosed among first-degree family members. Future studies are needed to determine the relative contribution of genes and shared environment to the risk of both cancers.

Abstract
OBJECTIVE Whether a first-degree family history of others cancers (FHOC) than breast or ovarian cancer (BOC) is associated with breast cancer prognosis remains unknown. Thus, the aim of the present study was to clarify this issue. METHODS Women who were diagnosed with invasive breast cancer at the Renmin Hospital of Wuhan University from 2010 to 2013 were included in the study. The demographic and clinicopathological characteristics of these patients were extracted. FHOC was considered positive for any patient who had a relative who had been diagnosed with cancer other than BOC. Disease-free survival (DFS) was calculated based on the date of diagnosis. DFS was analyzed using the Cox proportional hazards model. RESULTS A total of 434 breast cancer patients were included in this study. Among these patients, 61 (14.06%) had a positive FHOC in first-degree relatives. Patients with a positive FHOC tended to have HER2-positive breast cancer (p = 0.03). In the survival analysis, FHOC was associated with poor DFS in both univariate (HR = 2.21 (1.28-3.83), 95% CI: 1.28-3.83, p < 0.01) and multivariate (HR = 2.50, 95% CI: 1.24-5.04, p = 0.01) analyses, especially in patients with luminal A subtypes. CONCLUSION The results demonstrated an increased risk of recurrence in breast cancer patients with FHOC, especially in patients with luminal A subtype.

Abstract
Consumers usually do not know the complicated links between related health problems. This fact may cause troubles when they wish to seek complete information regarding such problems. This study detects the associations among health problems by extending the meaning of health terms with methods based on the latent Dirichlet allocation (LDA) probability topic model, the Medical Subject Headings (MeSH) thesaurus structure and the Wikipedia concept mapping. The terms represented health problems are selected from and extended by the consumer-level medical text. The vocabulary is different between the consumer-level and the professional-level medical text. Thus, the findings can be easily understood by the general public and be suitable to consumer-oriented applications. The methods were evaluated in two ways: (1) correlation analysis with expert rating to show the overall performance and (2) P@ N to reflect the ability of detecting strong associations. The LDA topic-model-based method outperforms the other two types. The judgment incongruence between the best method and the expert ratings has been examined, and the evidence shows that the automatic method sometimes detects real associations beyond those identified by human experts.

Abstract
Prostate cancer is the most commonly diagnosed cancer among men in the United States as well as most Western countries. A significant proportion of men report having a positive family history of prostate cancer in a first-degree relative (father, brother, son), which is important in that family history is one of the only established risk factors for the disease and plays a role in decision-making for prostate cancer screening. Familial aggregation of prostate cancer is considered a surrogate marker of genetic susceptibility to developing the disease, but shared environment cannot be excluded as an explanation for clustering of cases among family members. Prostate cancer is both a clinically and genetically heterogeneous disease with inherited factors predicted to account for 40%-50% of cases, comprised of both rare highly to moderately penetrant gene variants, as well as common genetic variants of low penetrance. Most notably, HOXB13 and BRCA2 mutations have been consistently shown to increase prostate cancer risk, and are more commonly observed among patients diagnosed with early-onset disease. A recurrent mutation in HOXB13 has been shown to predispose to hereditary prostate cancer (HPC), and BRCA2 mutations to hereditary breast and ovarian cancer (HBOC). Genome-wide association studies (GWAS) have also identified approximately 100 loci that associate with modest (odds ratios <2.0) increases in prostate cancer risk, only some of which have been replicated in subsequent studies. Despite these efforts, genetic testing in prostate cancer lags behind other common tumors like breast and colorectal cancer. To date, National Comprehensive Cancer Network (NCCN) guidelines have highly selective criteria for BRCA1/2 testing for men with prostate cancer based on personal history and/or specific family cancer history. Tumor sequencing is also leading to the identification of germline mutations in prostate cancer patients, informing the scope of inheritance. Advances in genetic testing for inherited and familial prostate cancer (FPC) are needed to inform personalized cancer risk screening and treatment approaches.

Mehrgou A, Akouchekian M. The importance of BRCA1 and BRCA2 genes mutations in breast cancer development. Med J Islam Repub Iran 2016; 30:369. [PMID: 27493913 PMCID: PMC4972064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2016] [Accepted: 02/22/2016] [Indexed: 11/08/2022] Open
Abstract
Many factors including genetic, environmental, and acquired are involved in breast cancer development across various societies. Among all of these factors in families with a history of breast cancer throughout several generations, genetics, like predisposing genes to develop this disease, should be considered more. Early detection of mutation carriers in these genes, in turn, can play an important role in its prevention. Because this disease has a high prevalence in half of the global population, female screening of reported mutations in predisposing genes, which have been seen in breast cancer patients, seems necessary. In this review, a number of mutations in two predisposing genes (BRCA1 and BRCA2) that occurred in patients with a family history was investigated. We studied published articles about mutations in genes predisposed to breast cancer between 2000 and 2015. We then summarized and classified reported mutations in these two genes to recommend some exons which have a high potential to mutate. According to previous studies, exons have been reported as most mutated exons presented in this article. Considering the large size and high cost of screening all exons in these two genes in patients with a family history, especially in developing countries, the results of this review article can be beneficial and helpful in the selection of exon to screen for patients with this disease.

Family History of Cancer in Relation to Breast Cancer Subtypes in African American Women. Cancer Epidemiol Biomarkers Prev 2015; 25:366-73. [PMID: 26721669 DOI: 10.1158/1055-9965.epi-15-1068] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2015] [Accepted: 12/10/2015] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND The evidence on the relation of family history of cancers other than breast cancer to breast cancer risk is conflicting, and most studies have not assessed specific breast cancer subtypes. METHODS We assessed the relation of first-degree family history of breast, prostate, lung, colorectal, ovarian, and cervical cancer and lymphoma or leukemia, to the risk of estrogen receptor-positive (ER(+)), ER(-), and triple-negative breast cancer in data from the African American Breast Cancer Epidemiology and Risk Consortium. Multivariable logistic regression models were used to calculate ORs and 95% confidence intervals (CI). RESULTS There were 3,023 ER(+) and 1,497 ER(-) breast cancer cases (including 696 triple-negative cases) and 17,420 controls. First-degree family history of breast cancer was associated with increased risk of each subtype: OR = 1.76 (95% CI, 1.57-1.97) for ER(+), 1.67 (1.42-1.95) for ER(-), and 1.72 (1.38-2.13) for triple-negative breast cancer. Family history of cervical cancer was associated with increased risk of ER(-) (OR = 2.39; 95% CI, 1.36-4.20), but not ER(+) cancer. Family history of both breast and prostate cancer was associated with increased risk of ER(+) (3.40; 2.42-4.79) and ER(-) (2.09; 1.21-3.63) cancer, but family history of both breast and lung cancer was associated only with ER(-) cancer (2.11; 1.29-3.46). CONCLUSIONS A family history of cancers other than breast may influence the risk of breast cancer, and associations may differ by subtype. IMPACT Greater surveillance and counseling for additional screening may be warranted for women with a family history of cancer.
