Abstract
Objectives As a convenient and economical method of screening cervical cancer and precancerous pathologies, the Papanicolaou smear (Pap smear) has been most widely used. Nevertheless, it requires cytological changes for making diagnoses and reportedly has a high false-negative rate. In this study, the usefulness of the human papillomavirus (HPV) DNA chip test as a complementary method that can compensate for the defect of the Pap smear was investigated. Material and Methods Of the 6516 patients who simultaneously underwent a Pap smear and an HPV DNA chip test at Chonnam National University Hospital between January 2015 and December 2016, 1897, an initial PAP smear-negative patients who had undergone an additional Pap smear during their 2-year follow-up period were selected for this study. Of the subject patients, 281 underwent a cervical biopsy. Results The Pap smear follow-up of an initial Pap smear-negative subjects showed 53 (75.7%) HPV high-risk positive cases in the cytology low-grade lesion group (70 cases) and 46 (97.8%) HPV high-risk positive cases in the cytology high-grade lesion group (47 cases). The 281 biopsy cases included 67 biopsy low-grade lesion cases and 74 biopsy high-grade lesion cases, of which there were 45 (67.2%) and 67 (90.5%) HPV high-risk positive cases, respectively. The follow-up cytology on the high-risk HPV-positive subjects showed that the ratio of their high-grade lesions was 260.8 times greater than that of the high-risk HPV-negative subjects (OR = 260.8 and 95% CI: 36.1 and 1886.1); and their biopsy showed that the ratio of their high-grade lesions was 102.7 times greater than that of the HPV-negative subjects (OR = 102.7 and 95% CI: 14.0 and 753.3). Conclusion The complementary use of the HPV DNA chip test may be useful in increasing the accuracy of screening examinations for the early diagnosis of uterine cervix cancer when combined with the Pap smear.

Abstract
INTRODUCTION Lung cancer remains the leading cause of death from cancer, worldwide. Developing early detection diagnostic methods, especially non-invasive methods, is a critical component to raising the overall survival rate and prognosis for lung cancer. The purpose of this study is to evaluate two protocols of a novel in vitro cellular immune response test to detect lung cancer. The test specifically quantifies the glycolysis metabolism pathway, which is a biomarker for the activation level of immune cells. It summarizes the results of two clinical trials, where each deploys a different protocol's version of this test for the detection of lung cancer. In the later clinical trial, an improved test protocol is applied. METHOD The test platform is based on changes in the metabolic pathways of the immune cells following their activation by antigenic stimuli associated with Lung cancer. Peripheral Blood Mononuclear Cells are loaded on a multiwell plate together with various lung tumor associated antigens and a fluorescent probe that exhibits a pH-dependent absorption shift. The acidification process in the extracellular fluid is monitored by a commercial fluorescence plate reader device in continuous reading for 3 h at 37 °C to document the fluorescent signal received from each well. RESULTS In the later clinical trial, an improved test protocol was applied and resulted in increased test accuracy. Specificity of the test increased to 94.0% and test sensitivity increased to 97.3% in lung cancer stage I, by using the improved protocol. CONCLUSION The improved protocol of the novel cellular immune metabolic response based test detects stage I and stage II of lung cancer with high specificity and sensitivity, with low material costs and fast results.

Abstract
BACKGROUND: Breast lumps are a common presentation that can be assess non-invasively using the ultrasonic examination.
AIM: The study aimed to assess the effect of different anatomical and physiological factors on the outcome of ultrasonic scoring of breast lumps.
METHODS: A total of 60 females presented with a breast lump on ultrasound assessment were randomly selected after their consent at the Clinic for Early Detection of Breast Cancer in Baghdad. The results were expressed according to the ultrasound breast imaging reporting and data system (BI-RADS) scoring.
RESULTS: There was a statistically significant positive correlation between the BI-RADS score with breast size, age, postmenopausal state, and personal or familial history of breast disease. Most cases (46.7%) scored BI-RADS II, followed by scores of III (21.6%), 4 (16.7%), and V (15%). The upper lateral quadrant of the breast was the most commonly affected sites. Marital status, parity, and breastfeeding didn’t have statistically significant influence on the sores.
CONCLUSION: Ultrasonic BI-RADS scoring of breast lumps provides an initial reliable tool for the management of breast disease. Higher scores are associated with increasing breast size, age, postmenopausal state, and personal or familial history of breast disease. Several anatomical, physiological, hereditary, and environmental aspects influence such factors.

Abstract
BACKGROUND Early diagnosis will significantly improve the survival rate of colorectal cancer (CRC); however, the existing methods for CRC screening were either invasive or inefficient. There is an emergency need for novel markers in CRC's early diagnosis. Serum proteomics has gained great potential in discovering novel markers, providing markers that reflect the early stage of cancer and prognosis prediction of CRC. In this paper, the results of proteomics of CRC studies were summarized through a meta-analysis in order to obtain the diagnostic efficiency of novel markers. METHODS A systematic search on bibliographic databases was performed to collect the studies that explore blood-based markers for CRC applying proteomics. The detection and validation methods, as well as the specificity and sensitivity of the biomarkers in these studies, were evaluated. Newcastle- Ottawa Scale (NOS) case-control studies version was used for quality assessment of included studies. RESULTS Thirty-four studies were selected from 751 studies, in which markers detected by proteomics were summarized. In total, fifty-nine proteins were classified according to their biological function. The sensitivity, specificity, or AUC varied among these markers. Among them, Mammalian STE20-like protein kinase 1/ Serine threonine kinase 4 (MST1/STK4), S100 calcium-binding protein A9 (S100A9), and Tissue inhibitor of metalloproteinases 1 (TIMP1) were suitable for effect sizes merging, and their diagnostic efficiencies were recalculated after merging. MST1/STK4 obtained a sensitivity of 68% and a specificity of 78%. S100A9 achieved a sensitivity of 72%, a specificity of 83%, and an AUC of 0.88. TIMP1 obtained a sensitivity of 42%, a specificity of 88%, and an AUC of 0.71. CONCLUSION MST1/STK4, S100A9, and TIMP1 showed excellent performance for CRC detection. Several other markers also presented optimized diagnostic efficacy for CRC early detection, but further verification is still needed before they are suitable for clinical use. The discovering of more efficient markers will benefit CRC treatment.

Abstract
Background Tamoxifen is the cornerstone of adjuvant therapy for hormone receptor-positive breast cancer. Despite its efficacy, limited drug sensitivity and endocrine resistance remain the important clinical challenges. The main objective of this study was to investigate fatostatin, which was found to sensitize breast cancer to the antitumour effect of tamoxifen both in vitro and in vivo. Methods Fatostatin-induced ER degradation was detected by immunoprecipitation assay. The antitumour effect of fatostatin and tamoxifen on MCF-7 and T47D cells was assessed by MTT and colony forming assays. Cell cycle arrest was detected by flow cytometric analysis. Apoptosis was detected by annexin V/propidium iodide double staining and TUNEL assay. Autophagy was detected by MDC assay and acridine orange staining. Migration and invasion assays were performed using a Transwell system, and the efficacy of the synergistic use of fatostatin and tamoxifen in vivo was evaluated using an MCF-7 xenograft model in BALB/c nu/nu female mice. Results The synergistic use of fatostatin and tamoxifen significantly suppressed cell viability and invasion, induced cell cycle arrest, and regulated apoptosis and autophagy in MCF-7 and T47D cell lines via PI3K-AKT-mTOR signalling. Additionally, the expression levels of Atg7/12/13, beclin and LC3B increased while p-mTOR and P62 expression levels decreased after treatment with fatostatin and tamoxifen. Tumor growth in the xenograft model was suppressed significantly with the synergistic treatment of fatostatin and tamoxifen. Conclusion Fatostatin could induce ER degradation by K48-linked polyubiquitination, which was the key mechanism contributing to tamoxifen inhibition of PI3K-AKT-mTOR signalling in breast cancer. Fatostatin may have a promising clinical use for ER-positive breast cancer patients.

Abstract
Silver nanoparticles were synthesized by chemical reduction of silver nitrate using arabinogalactan polysaccharide as a reducing agent and a stabilizer. The average size of nanoparticles, obtained by analyzing TEM-images, was 10.8[Formula: see text]nm; zeta potential [Formula: see text][Formula: see text]mV. A study of the sol by electron diffraction showed that silver in the sample is in metallic form. The resulting preparation of silver nanoparticles showed both antibacterial and antifungal activity. A pronounced antibacterial activity of silver nanoparticles was demonstrated both in relation to conditionally pathogenic gram-positive (Bacillus subtilis and B. coagulans) and gram-negative (Escherichia coli) bacteria. Silver nanoparticles also possess antifungal activity against macromycete Fomitopsis sp., as well as two strains of micromycetes Trichoderma citrinoviride and Fusarium sporotrichioides. Using the methods of light and fluorescence microscopy, MTT-analysis and Real-time cell analysis, the cytotoxic activity of silver nanoparticles was investigated on HepG2 human hepatocellular carcinoma cells. It was demonstrated that nanoparticles cause a suppression of cell metabolic and proliferative activity, as well as dose-dependent induction of cell death (average relative EC[Formula: see text] value was [Formula: see text]g/ml). The preparation of silver nanoparticles stabilized by arabinogalactan can be used in medicine, as a potential antimicrobial and antitumor agent.

Abstract
INTRODUCTION Colorectal cancer is one of the most sprayed cancers; the gold standard of diagnostic is a colonoscopy. The quality of this examination is depended on many factors, which includes doctors' experience. PURPOSE The purpose of this study is to establish the main factors affecting the completeness of colonoscopy in colorectal cancer screening. MATERIALS AND METHODS Endoscopists were questioned; descriptive statistics methods and logistic regression were used. RESULTS AND DISCUSSION The main factors that influence the quality of screening colonoscopy were identified: experience in colonoscopy, theoretical training, participation in the screening program, and number of annual colonoscopies. The calculated odds ratio for the selected dependent variable is calculated. CONCLUSIONS The experience for more than 5 years (p = 0.017) and at least 200 colonoscopies per year (p = 0.004) are the main factors that allow to perform complete colonoscopy in 90% or more of cases.

Abstract
BACKGROUND Breast diseases in women, whether benign or malignant, are very commonly encountered. The breast is the commonest site for female cancer in Egypt (38.8%). Breast cancer screening can reduce morbidity and mortality and improve the survival rate for this malignancy. Mammogram can be used as a screening technique beside its role as diagnostic, especially in women over 40 years of age. OBJECTIVES To assess knowledge, attitude and practice regarding breast cancer and awareness about mammogram as a screening method among a group of females attending Ain Shams University outpatient clinics. METHODS A cross-sectional study was performed from August to September 2017. A systematic random sample was taken from attending females (18-70 years) in Ain Shams University outpatient clinics (Internal Medicine, Surgery, Pediatrics Hospital, and Maternity hospital). They were interviewed using a questionnaire inquiring about sociodemographic background, participants' knowledge, attitude, and practice towards breast cancer and its screening. RESULTS The mean age ± SD of attending females (18-70 years) was 37 ± 11 years. Most study participants had correct information about mammography. They showed poor knowledge level about risk factors. Mass media such as TV and internet were identified as the main source of information on breast cancer by 43% and 23.9%, respectively. In general, participants had positive attitude towards breast cancer screening by mammography. Around 90% agreed that mammogram was the best way to find a very small lump in the breast, and 91.4% agreed that women who have regular screening by mammogram have better disease outcome than those who do not screen. Regarding mammography practice rate, a small percent of participants (8.1%) was advised by their doctors to conduct a screening mammography. The level of knowledge was significantly and positively correlated with their attitude towards breast cancer screening. CONCLUSION The poor knowledge and practices of women illustrate the need for health education program directed to Egyptian females to improve their knowledge about breast cancer-especially its risk factors-and its screening. Using TV and Internet as media for spreading information about this disease is crucial.

Abstract
Background: Effective screening of colorectal cancer (CRC) in early stage could reduce the advancement of CRC and therefore mortality. Effective screening is based on either stool dependent tests or colon dependent examination. Aims: The aim of the study was a comparative evaluation of chromocolonoscopy and Colon Cancer-Specific Antigen-2 test for early detection of colorectal cancer in Egyptian patients. Methods: This case control study was carried out on 55 patients classified into 3 groups: Group I consisted of twenty patients with precancerous lesions detected by colonoscopy, Group II consisted of twenty patients diagnosed with colorectal cancer and Group III consisted of fifteen individuals (who underwent colonoscopy for other indications) as a control group. All the subjects were subjected to measure occult blood in the stool, measurement of Colon Cancer-Specific Antigen-2 level in serum and tissue and chromo colonoscopy using Indigo Carmine stain. Results: In group II, there was a statistically significant increase in CCSA2 in serum as compared to the other 2 groups. Cutoff >11.3 CCSA2 in serum showed 65% sensitivity, 85% specificity, 81.2% PPV, 70.8% NPV and 70.3% accuracy in the differentiation of group II with cancer colon from group I with premalignant colonic lesions. A cutoff > 9.1 CCSA2 in serum showed 95% sensitivity, 46.67% specificity, 70.4% PPV, 87.5% NPV and 73.5% accuracy in differentiating group II with cancer colon from normal controls (group III). Conclusion: CCSA-2 level in serum was significantly higher in cancer colon. Chromoendoscopy has a role in the detection of polyps, both neoplastic and non-neoplastic.

Abstract
INTRODUCTION Testicular self-examination (TSE) is a screening technique that involves inspection of the appearance and palpation of the testes to detect any changes from the normal. Globally, the incidence of cancer has increased among which is testicular cancer (TC). Data on this topic among male secondary school adolescents in Uganda is limited therefore this study sought to assess the knowledge and practice of testicular self-examination among secondary students at Ntare School, Mbarara District in south western Uganda. The objective of the study is to assess the knowledge and practice of testicular self-examination among secondary students at Ntare School in Mbarara district, south western Uganda. METHODS We conducted a descriptive cross-sectional quantitative study among 165 students. Recruitment was made using simple random sampling technique. Respondents were selected among advanced level (A' level) male students studying at Ntare School in Mbarara district, south western Uganda. Structured self-administered questionnaires were used for data collection. RESULTS Of the male students, 41.8% reported to have knowledge about TSE and only 23.6% practiced TSE. Most students rated their knowledge of TSE to be below 5 (from 1-10). Of the 39 students who admitted performing TSE, only 16 did so as recommended (monthly). CONCLUSION The knowledge and practice of TSE were low among adolescent secondary school boys in Ntare School in Mbarara District, south western Uganda. This suggests that these students are unaware of the value of this personal health promotion tool which is fundamental in early diagnosis of testicular cancer.

Abstract
BACKGROUND Younger women at higher-than-population-average risk for breast cancer may benefit from starting screening earlier than presently recommended by the guidelines. The Personalized Risk Stratification for Prevention and Early Detection of Breast Cancer (PERSPECTIVE) approach aims to improve the prevention of breast cancer through differential screening recommendations based on a personal risk estimate. In our study, we used deliberative stakeholder consultations to engage health professionals in an in-depth dialog to explore the feasibility of the proposed implementation strategies for this new personalized breast cancer screening approach. METHODS Deliberative stakeholder consultation is a qualitative descriptive study design used to engage health professionals in the discussion, while the mediators play a more passive role. A purposeful sample of 11 health professionals (family physicians and genetic counselors) working in Montreal was used. The deliberations were organized in two phases, including small group deliberations according to the deliberants' health profession and a mixed group deliberation combining participants from the small groups. Inductive thematic content analysis was performed on the transcripts by two coders to create the deliberative and analytic outputs. Quality of deliberations was assessed quantitatively using the de Vries method and qualitatively using participant observation. RESULTS One of our key findings was that health professionals lacked understanding of the two steps of the screening approach: risk stratification "screening," which is an evaluation for the level of risk and screening for disease. As part of this confusion, the main topic of concern was a justification of program implementation as a population-wide screening, based on their uncertainty that it will be beneficial for women with near-population risks. Despite the noted difficulties concerning implementation, health professionals acknowledged the substantial benefits of the proposed PERSPECTIVE program. CONCLUSIONS Our study was the first to evaluate the perspectives of health professionals on the implementation and benefits of a new program for breast cancer risk stratification with the purpose of personalizing screening for disease. This new multi-step approach to screening requires more clarity in communication with health professionals. To implement and maintain effective screening, engagement of family physicians with other health professionals or even development of a centralized public health system may be needed.

Abstract
Tamoxifen is the most widely used hormone therapy in estrogen receptor-positive (ER+) breast cancer, which accounts for approximately 70% of all breast cancers. Although patients who receive tamoxifen therapy benefit with respect to an improved overall prognosis, resistance and cancer recurrence still occur and remain important clinical challenges. A recent study identified TAR (HIV-1) RNA binding protein 2 (TARBP2) as an oncogene that promotes breast cancer metastasis. In this study, we showed that TARBP2 is overexpressed in hormone therapy-resistant cells and breast cancer tissues, where it enhances tamoxifen resistance. Tamoxifen-induced TARBP2 expression results in the desensitization of ER+ breast cancer cells. Mechanistically, tamoxifen post-transcriptionally stabilizes TARBP2 protein through the downregulation of Merlin, a TARBP2-interacting protein known to enhance its proteasomal degradation. Tamoxifen-induced TARBP2 further stabilizes SOX2 protein to enhance desensitization of breast cancer cells to tamoxifen, while similar to TARBP2, its induction in cancer cells was also observed in metastatic tumor cells. Our results indicate that the TARBP2-SOX2 pathway is upregulated by tamoxifen-mediated Merlin downregulation, which subsequently induces tamoxifen resistance in ER+ breast cancer.

Abstract
This study assessed if race and gender predict known sexual risk factors associated with HPV. Data (n = 301) were from a cross-sectional study conducted at a drag racing event on September 12–13, 2015 in Madison, Illinois. Both multivariable logistic and linear regression models estimated the association between race, gender, and sexual risk factors. About 63% of participants were males, and 65% identified as Blacks. Compared to females, males were more likely to have a higher number of oral sexual partners (OR = 2.10; 95% CI: 1.23, 3.57). Males were also more likely to have earlier oral sexual (b = −2.10; 95% CI: −3.60, −0.60) and vaginal sexual (b = −1.10; 95% CI: −1.69, −0.31) debuts compared to females. Blacks were more likely to have higher number of vaginal sexual partners (OR = 3.38; 95% CI: 1.81, 6.31) and earlier vaginal sex (b = −1.09; 95% CI: −1.78, −0.41) but less likely to have earlier oral sexual debuts compared with Whites (b = 2.67; 95% CI: 1.21, −4.13). Because HPV is associated with several cancers, our findings provide impetus for the development of targeted educational interventions aimed at improving the knowledge of these sexual risk factors, especially among men and across race groups.

Abstract
BACKGROUND Alzheimer's disease and related dementias (ADRD) impact a woman's life expectancy and her ability to participate in medical decision-making about breast cancer screening, necessitating the involvement of family caregivers. Making decisions about mammography screening for women with ADRD is stressful. There are no data that suggest that breast cancer screening helps women with ADRD live longer or better. Decision aids may improve the quality of decision-making about mammography for ADRD patients and may inform family caregivers about the risks, benefits, and need for decision-making around mammography screening. METHODS/DESIGN The Decisions about Cancer Screening in Alzheimer's Disease (DECAD) trial, a randomized controlled clinical trial, will enroll 426 dyads of older women with ADRD (≥75 years) and a family caregiver from clinics and primary-care practices in Indiana to test a novel, evidence-based decision aid. This decision aid includes information about the impact of ADRD on life expectancy, the benefit of mammograms, and the impact on the quality of life for older women with ADRD. Dyads will be randomized to receive the decision aid or active control information about home safety. This trial will examine the effect on the caregiver's decisional conflict (primary outcome) and the caregiver's decision-making self-efficacy (secondary outcome). A second follow-up at 15 months will include a brief, semi-structured interview with the caregiver regarding the patient's experience with mammograms and decision-making about mammograms. At the same time, a review of the patient's electronic medical record (EMR) will look at discussions about mammography with their primary-care physician and mammogram orders, receipt, results, and burden (e.g., additional diagnostic procedures due to false-positive results, identification of an abnormality on the screening exam but further work-up declined, and identification of a clinically unimportant cancer). A third follow-up at 24 months will extract EMR data on mammogram orders, occurrences, results, and the burden of mammograms. DISCUSSION We hypothesize that caregivers who receive the decision aid will have lower levels of decisional conflict and higher levels of decision-making self-efficacy compared to the control group. We also hypothesize that the DECAD decision aid will reduce mammography use among older women with ADRD. TRIAL REGISTRATION Clinical Trials Register, NCT03282097 . Registered on 13 September 2017.

Abstract
BACKGROUND Colorectal cancer (CRC) is one of the most predominant types of cancer, and it is the fourth most common cause of cancer-related death and it is important to diagnose CRC in early stage to decrease the mortality by CRC. In our previous study, we identified a combination of five peptides as a biomarker candidate to diagnose CRC by BLOTCHIP®-MS analysis using a set of healthy control subjects and CRC patients (stage II-IV). The aim of the present study was to validate the serum biomarker peptides reported in our previous study using a second cohort and to establish their potential usefulness in CRC diagnosis. METHODS A total of 56 patients with CRC (n = 14 each of stages I-IV), 60 healthy controls, and 60 patients with colonic adenoma were included in this study. The five peptides were extracted and analyzed by selected reaction monitoring using ProtoKey® Colorectal Cancer Risk Test Kit (Protosera, Inc., Amagasaki, Japan). RESULTS The results clearly showed that the four CRC groups, stages I-IV, could be sufficiently discriminated from the control group and colonic polyp group. This five-peptide set could identify CRC at each stage compared to the control population in this validation cohort, including those with early-stage disease. The AUC values for each stage of CRC compared to the control population were 0.779, 0.946, 0.852, and 0.973 for stages I, II, III, and IV, respectively. CONCLUSIONS In this case-control validation study, we confirmed high diagnostic performance for CRC using five peptides that were identified in our previous study as serum biomarker candidates for the detection of CRC.

Abstract
Lung cancer is the leading cause of cancer death worldwide. Survival is largely dependent on the stage of diagnosis: the localized disease has a 5-year survival greater than 55%, whereas, for spread tumors, this rate is only 4%. Therefore, the early detection of lung cancer is key for improving prognosis. In this study, we present an innovative, non-invasive, cancer detection approach based on measurements of the metabolic activity profiles of immune system cells. For each Liquid ImmunoBiopsy test, a 384 multi-well plate is loaded with freshly separated PBMCs, and each well contains 1 of the 16 selected stimulants in several increasing concentrations. The extracellular acidity is measured in both air-open and hermetically-sealed states, using a commercial fluorescence plate reader, for approximately 1.5 h. Both states enable the measurement of real-time accumulation of 'soluble' versus 'volatile' metabolic products, thereby differentiating between oxidative phosphorylation and aerobic glycolysis. The metabolic activity profiles are analyzed for cancer diagnosis by machine-learning tools. We present a diagnostic accuracy study, using a multivariable prediction model to differentiate between lung cancer and control blood samples. The model was developed and tested using a cohort of 200 subjects (100 lung cancer and 100 control subjects), yielding 91% sensitivity and 80% specificity in a 20-fold cross-validation. Our results clearly indicate that the proposed clinical model is suitable for non-invasive early lung cancer diagnosis, and is indifferent to lung cancer stage and histological type.

Abstract
OBJECTIVE The expression of miR-338-5p has been reported to be upregulated in colorectal cancer (CRC) tissues. Clinicopathological features indicate that miR-338-5p overexpression correlates with the metastatic status of CRC. This study was aimed to investigate the diagnostic value of serum miR-338-5p for CRC. METHODS Peripheral blood samples were collected from 210 participants, including 80 patients with CRC, 50 with colorectal polyps and 80 healthy controls. Serum miR-338-5p was quantified by quantitative reverse-transcription polymerase chain reaction. The area under the receiver operating characteristic curve (AUROC) was used to estimate the diagnostic value of miR-338-5p, carcinoembryonic antigen (CEA) and the combination of these two biomarkers. RESULTS Serum miR-338-5p levels (fold change) in patients with CRC and colorectal polyps, and controls were 4.94 ± 1.13, 4.12 ± 0.75 and 3.07 ± 0.75, respectively. Significant differences were observed between the groups (P < 0.001). The AUROC of miR-338-5p was 0.923 (95% CI 0.882-0.964) and 0.845 (95% CI 0.792-0.898), respectively, for distinguishing CRC from healthy controls or from those without CRC. The AUROC of the combination of miR-338-5p and CEA was 0.932 (95% CI 0.882-0.964), with a sensitivity of 85%, a specificity of 88.8% at a cut-off value of 8.16. CONCLUSIONS Circulating miR-338-5p may serve as a potential noninvasive diagnostic biomarker for detecting CRC. The combination of miR-338-5p and CEA exhibits the highest diagnostic value in our study.

Abstract
Routine prostate cancer screening is not recommended but African American men who are at higher risk for the disease should be offered the opportunity for shared decision-making with their health-care providers. This qualitative study sought to better understand the potential role of women in educating their male spouses/partners about prostate cancer screening. Nine focus groups were conducted ( n = 52). Women were recruited from a variety of community venues. Those eligible were African American and married to or in a partnership with an African American male age ≥ 45. Women provide numerous types of support to their male partners in an effort to facilitate participation in preventive health care. While women agreed that they would like to educate their partners about prostate cancer screening, they had little information about screening guidelines or the potential harms and limitations. The current findings suggest that women are eager information-seekers and can disseminate information to men and facilitate their efforts to make more informed decisions about prostate cancer screening. Women should be included in educational interventions for to promote informed decision-making for prostate cancer screening.

Abstract
We herein report the synthesis, biological activity and preliminary structure-activity relationships of a series of diaryl[1,3]diazepines. These compounds were able to inhibit the proliferation of many cancer cell lines, such as HeLa, MCF-7, SGC7901 and A549. When HeLa cells were treated with lead compounds 7j and 7k at 3 [Formula: see text] concentration, cell arrest was observed in the G2/M phase.

Abstract
Prostate cancer (PCa) is the second most common cancer among men worldwide. Its etiology remains largely unknown compared to other common cancers. We have developed a risk stratification model combining environmental factors with family history and genetic susceptibility. 818 PCa cases and 1,006 healthy controls were compared. Subjects were interviewed on major lifestyle factors and family history. Fifty-six PCa susceptibility SNPs were genotyped. Risk models based on logistic regression were developed to combine environmental factors, family history and a genetic risk score. In the whole model, compared with subjects with low risk (reference category, decile 1), those carrying an intermediate risk (decile 5) had a 265% increase in PCa risk (OR = 3.65, 95% CI 2.26 to 5.91). The genetic risk score had an area under the ROC curve (AUROC) of 0.66 (95% CI 0.63 to 0.68). When adding the environmental score and family history to the genetic risk score, the AUROC increased by 0.05, reaching 0.71 (95% CI 0.69 to 0.74). Genetic susceptibility has a stronger risk value of the prediction that modifiable risk factors. While the added value of each SNP is small, the combination of 56 SNPs adds to the predictive ability of the risk model.

Abstract
A concise and efficient synthetic approach has been established to readily access a series of novel C-14 1,2,3-triazole-tethered dehydroabietic acid derivatives in moderate to high yields. In vitro antiproliferative activity evaluation indicated that most of the hybrids exhibited potent inhibitory activities in a variety of cancer cell lines with low micromolar to submicromolar IC50 values. Further studies demonstrated that some of these analogues such as 20, 21, and 24 were also effective against adriamycin-resistant MCF-7 clone at low concentrations in a dose-dependent manner. Notably, the most potent compound 24, which possesses a 3-(tert-butoxycarbonylamino)phenyl-substituted triazole moiety, not only exhibited obviously improved IC50 values ranging from 0.7 to 1.2 μM against a panel of tested cancer cells, but also showed very weak cytotoxicity on normal cells. Preliminary mechanism studies indicated that compound 24 could induce apoptosis in MDA-MB-231 cells and was worth developing into a novel natural product-like anticancer lead by proper structure modification.

Abstract
Objective: The aim of this study is to detect breast cancer rate, nodal status, tumor size, and associated risk factors using clinical breast examination (CBE) and mammography as screening tools in women aged 40–49 years. Materials and Methods: A total of 500 women were screened in a time period of 2 years, between the ages of 40–49 years for breast cancer. Screening tools used were CBE and mammography. Clinical history and risk factors related to breast cancer were recorded. CBE was performed to detect any breast pathology followed by mammographic screening. Breast Imaging Reporting and Data System (BI-RADS) mammographic density categories were used for reporting breast imaging on mammography. For women with dense breasts or an inconclusive mammography report, ultrasonography was performed to assess the lesion/s. Suspicious lesion was subjected to fine-needle aspiration cytology or an open surgical biopsy for a confirmatory diagnosis. Women with history of breast cancer were excluded from the study. Results: CBE was normal in almost 90% of the women. Screening mammography revealed Breast Imaging Reporting and Data System (BI-RADS) I and BI-RADS II in 58.4% and 34.6% of women, respectively. Only 7% of women belonged to BI-RADS III and none in BI-RADS IV category. Conclusion: The study findings are in agreement with the recommendations of the World Health Organization, US preventive task force and UK guidelines that recommend screening mammography in women starting at 50 years.

Abstract
No single biological marker is used in routine diagnosis of colorectal cancer (CRC) in endoscopic biopsies. IMP3 is a good independent prognostic biomarker for CRC. However, the expression of IMP3 in hyperplastic polyp (HP) and adenoma has not yet been studied. Moreover, no studies have established the diagnostic value of IMP3 in biopsies. This study aims to assess IMP3 expression in HP, adenoma, and CRC in resection specimens and to investigate its value in diagnosis of CRC in biopsies. A total of 1328 specimens (633 of polypectomy, 395 surgical resections, 300 biopsies) were retrospectively analyzed. IMP3 expression was observed in 0 of 197 (0%) normal tissues, 0 of 130 (0%) HPs, 14 of 504 (2.8%) adenomas, and 139 of 197 (70.6%) CRCs. IMP3 was found to be overexpressed in CRC compared with adenoma (P<.001). Among the 300 biopsies, 56 were diagnosed as adenoma, and 244 were CRCs. Of the 56 adenoma cases, 22 (39.3%) were confirmed, whereas 34 (60.7%) were diagnosed as CRC in resection specimens. All 244 CRC biopsies were confirmed by resection specimens. IMP3-positive expression was observed in 204 of 300 (68.0%) biopsies, including in 22 of 56 (39.3%) adenomas and 182 of 244 (74.6%) CRCs. All IMP3-positive expressions in the biopsies were finally diagnosed as CRC. Our findings demonstrated that IMP3 is a reliable marker for the diagnosis of CRC in endoscopic biopsies.

Abstract
Health information can be presented in different formats, such as a statistically-based or a story-based (e.g. narrative) format; however, there is no consensus on the ideal way to present screening information. This systematic review summarizes the literature pertaining to narrative interventions' efficacy at changing screening behaviour and its determinants. Five psychology and public health databases were searched; 19 studies, 18 focused on cancer and 1 on sexual health, met eligibility criteria. There is consistent evidence supporting the efficacy of narratives, but mixed evidence supporting an advantage for narratives over statistical interventions for screening behaviour and its determinants. Further investigation is warranted.

Abstract
A series of new 1H-benzo[d]imidazole derivatives of dehydroabietic acid were designed and synthesized as potent antitumor agents. Structures of the target molecules were characterized using MS, IR, 1H NMR, 13C NMR and elemental analyses. In the in vitro cytotoxic assay, most compounds showed significant cytotoxic activities against two hepatocarcinoma cells (SMMC-7721 and HepG2) and reduced cytotoxicity against noncancerous human hepatocyte (LO2). Among them, compound 7b exhibited the best cytotoxicity against SMMC-7721 cells (IC50: 0.36±0.13μM), while 7e was most potent to HepG2 cells (IC50: 0.12±0.03μM). The cell cycle analysis indicated that compound 7b caused cell cycle arrest of SMMC-7721 cells at G2/M phase. Further, compound 7b also induced the apoptosis of SMMC-7721 cells in Annexin V-APC/7-AAD binding assay.

Abstract
Community-based participatory research (CBPR) is becoming one of the dominant approaches for bringing evidence- and consensus-based cancer prevention and control practices to medically underserved communities. There are many examples of how CBPR has been useful for generating culturally specific solutions for different health issues that affect African-Americans. However, few examples exist in the literature on how the CBPR approach can be applied to address prostate cancer. This paper describes a collaborative process for linking inner-city, African-American men to free prostate cancer education, physician counseling, and screening opportunities (prostate-specific antigen (PSA) testing and digital rectal examination (DRE)). The site of this community-based participatory project was the city of Buffalo, located in Erie County, New York. The collaborative, community-academic process that is described includes the following: (1) planning and conducting a community needs assessment to contextualize local prostate cancer issues, (2) organizing town and gown event planning, and (3) manipulating aspects of the built environment to build an infrastructure within the community to address disparities in screening opportunities. This paper concludes with a description of lessons learned that can help others develop and implement similar activities in other communities.

Abstract
The U.S. Preventive Services Task Force (USPSTF) recommended screening mammography every 1-2 years for women 40 years and older in 2002, and changed its recommendations in 2009 to no routine screening for women between 40 and 49 years of age; and biennial screening for women between 50 and 74 years of age. This study evaluates the change in mammographic use after the issuance of the revised recommendations. Women who participated in a cross-sectional study of breast cancer risk factors from 2007 to 2013 were asked if they had received a mammogram in the preceding 2 years. All 3442 study participants who enrolled in the study after January 1, 2011 were matched by race, age, and educational level with women enrolled between 2007 and 2010. The proportions of women who stated they had received a mammogram in the past 2 years were compared between the two groups. One fourth of the participants were African American and 39% were 40-49 years of age. Among white women, significant decreases in recent mammogram use from 2007-2010 to 2011-2013 were detected for women 40-49 years of age (-10.3%, p < 0.001) and 50-74 years of age (-8.8%, p < 0.001). Among African-American women, the change in recent mammogram use was not statistically significant for women 40-49 years of age (-2.7%, p = 0.440) or 50-74 years of age (-2.2%, p = 0.398). Following the change in the USPSTF guidelines, mammography use among white women declined; however, no change was observed among African-American women.

Abstract
BACKGROUND AND OBJECTIVE A large number of labeled medical image data is usually a requirement to train a well-performed computer-aided detection (CAD) system. But the process of data labeling is time consuming, and potential ethical and logistical problems may also present complications. As a result, incorporating unlabeled data into CAD system can be a feasible way to combat these obstacles. METHODS In this study we developed a three stage semi-supervised learning (SSL) scheme that combines a small amount of labeled data and larger amount of unlabeled data. The scheme was modified on our existing CAD system using the following three stages: data weighing, feature selection, and newly proposed dividing co-training data labeling algorithm. Global density asymmetry features were incorporated to the feature pool to reduce the false positive rate. Area under the curve (AUC) and accuracy were computed using 10 fold cross validation method to evaluate the performance of our CAD system. The image dataset includes mammograms from 400 women who underwent routine screening examinations, and each pair contains either two cranio-caudal (CC) or two mediolateral-oblique (MLO) view mammograms from the right and the left breasts. From these mammograms 512 regions were extracted and used in this study, and among them 90 regions were treated as labeled while the rest were treated as unlabeled. RESULTS Using our proposed scheme, the highest AUC observed in our research was 0.841, which included the 90 labeled data and all the unlabeled data. It was 7.4% higher than using labeled data only. With the increasing amount of labeled data, AUC difference between using mixed data and using labeled data only reached its peak when the amount of labeled data was around 60. CONCLUSIONS This study demonstrated that our proposed three stage semi-supervised learning can improve the CAD performance by incorporating unlabeled data. Using unlabeled data is promising in computerized cancer research and may have a significant impact for future CAD system applications.

Abstract
INTRODUCTION AND AIMS As inflammatory bowel diseases [IBD] affect female patients almost exclusively during their reproductive age, issues related to fertility, fecundity, pregnancy, delivery, and lactation are of utmost importance. Lack of education and misconceptions regarding the effect of disease and/or treatment on reproductive outcome may lead to voluntary childlessness and/or development of unwanted cervical pathologies which may impact tremendously on patients' welfare and quality of life. The aims of this study were to assess the perspectives of IBD patients on fertility, pregnancy and its outcomes, and lactation, as well as their awareness of human papillomavirus [HPV]-related pathologies and screening for cervical cancer. METHODS This prospective study was performed across nine different Mediterranean IBD centres between 2014 and 2015 and included consecutive female IBD patients between the ages of 16 and 50 years. All patients responded to a questionnaire based on ECCO guidelines. RESULTS A total of 348 IBD female patients with a mean age of 37.4 (standard deviation [SD] ± 2.1) years were recruited; 50% had a diagnosis of ulcerative colitis, 49.4% had Crohn`s disease, and 0.6% patients had a diagnosis of indeterminate colitis [IC]. A significant proportion of patients [ > 60%] were afraid that IBD may lead to a complicated pregnancy and that the disease itself and/or its medications can cause fetal harm. Patients had similar concerns that IBD can be transmitted to their offspring as well as with regard to breastfeeding. Counselling from health care professionals with regard to fertility, pregnancy, and lactation was associated positively with the highest number of pregnancies and inversely with the lowest number of patients who considered voluntary childlessness [p < 0.0001]. Patients with a higher level of education were more likely to get pregnant [p = 0.004]. There was a low uptake of the HPV vaccine. However, there was a reasonably good uptake of cervical cancer screening. CONCLUSION Our study demonstrates that women with IBD have misperceptions about fertility, pregnancy, and health maintenance. We also show that education by physicians has a positive influence. We thus conclude that improved multidisciplinary approaches should be used to educate and implement European guidelines for women with IBD.

Abstract
After the introduction of the prostate specific antigen (PSA) test in the 1980s, a sharp increase in the incidence rate of prostate cancer was seen in the United States. The age-specific incidence patterns exhibited remarkable shifts to younger ages, and declining rates were observed at old ages. Similar trends were seen in Norway. We investigate whether these features could, in combination with PSA testing, be explained by a varying degree of susceptibility to prostate cancer in the populations. We analyzed incidence data from the United States' Surveillance, Epidemiology, and End Results program for 1973-2010, comprising 511,027 prostate cancers in men ≥40 years old, and Norwegian national incidence data for 1953-2011, comprising 113,837 prostate cancers in men ≥50 years old. We developed a frailty model where only a proportion of the population could develop prostate cancer, and where the increased risk of diagnosis due to the massive use of PSA testing was modelled by encompassing this heterogeneity in risk. The frailty model fits the observed data well, and captures the changing age-specific incidence patterns across birth cohorts. The susceptible proportion of men is [Formula: see text] in the United States and [Formula: see text] in Norway. Cumulative incidence rates at old age are unchanged across birth cohort exposed to PSA testing at younger and younger ages. The peaking cohort-specific age-incidence curves of prostate cancer may be explained by the underlying heterogeneity in prostate cancer risk. The introduction of the PSA test has led to a larger number of diagnosed men. However, no more cases are being diagnosed in total in birth cohorts exposed to the PSA era at younger and younger ages, even though they are diagnosed at younger ages. Together with the earlier peak in the age-incidence curves for younger cohorts, and the strong familial association of the cancer, this constitutes convincing evidence that the PSA test has led to a higher proportion, and an earlier timing, of diagnoses in a limited pool of susceptible individuals.

Abstract
BACKGROUND All authorities recommend against prostate specific antigen (PSA) screening in men 75 years and older. However, some primary care physicians (PCPs) continue to have high rates of PSA, with large variation in testing. We assessed the tests, treatments, and payments for prostate cancer care in men aged 75 or older who have PCPs with high or low PSA testing rates. METHODS We performed a retrospective cohort study using the 2010 Medicare beneficiaries aged 75 or older in Texas, United States who had no prostate cancer in 2007-2009 and had an identifiable PCP. We first identified high vs. low PSA testing PCPs, and then grouped older men in the two PCP groups. We determined health care visits to any provider and to urologists in office and outpatient settings. We estimated the direct medical payments for prostate cancer care for diagnostics, treatments and visits to providers in 2010-2011 using the generalized gamma model with log link function. RESULTS In multilevel, multivariable analyses, 25.4% (n = 550) of PCPs had PSA testing rates in men aged 75 or older that were significantly higher than the mean rate of all 2,169 Texas PCPs; 29.4% (n = 638) had rates that were significantly lower. In all, 22,853 vs. 23,929 older men were cared for by PCPs with high vs. low testing rates. Older men cared for by high PSA rate PCPs were more likely to receive a PSA test (OR 3.64, 95% CI 3.48-3.80), a biopsy (OR 1.16, 95% CI 1.02-1.31), an ultrasound (OR 1.19, 95% CI 1.07-1.32) or any radiation treatment (OR 1.31, 95% CI 1.03-1.66) than men cared for by low PSA rate PCPs. Men with high PSA rate PCPs were 1.21 (95% CI 1.05-1.39) times more likely to have such outpatient visits. The average annual adjusted Medicare payments for prostate cancer care was $25.60 higher for patients cared for by PCPs with high PSA test rates. CONCLUSIONS Older men seeing PCPs with high rates of PSA testing undergo more testing and treatments for prostate cancer, with higher Medicare insurance payments. Future studies are needed to delineate whether men seeing PCPs with low testing rates likely received PSA tests from other providers.

Abstract
Epigenetic biomarkers, such as DNA methylation, can increase cancer risk through altering gene expression. The Cancer Genome Atlas (TCGA) Network has demonstrated breast cancer-specific DNA methylation signatures. DNA methylation signatures measured at the time of diagnosis may prove important for treatment options and in predicting disease-free and overall survival (tertiary prevention). DNA methylation measurement in cell free DNA may also be useful in improving early detection by measuring tumor DNA released into the blood (secondary prevention). Most evidence evaluating the use of DNA methylation markers in tertiary and secondary prevention efforts for breast cancer comes from studies that are cross-sectional or retrospective with limited corresponding epidemiologic data, raising concerns about temporality. Few prospective studies exist that are large enough to address whether DNA methylation markers add to the prediction of tertiary and secondary outcomes over and beyond standard clinical measures. Determining the role of epigenetic biomarkers in primary prevention can help in identifying modifiable pathways for targeting interventions and reducing disease incidence. The potential is great for DNA methylation markers to improve cancer outcomes across the prevention continuum. Large, prospective epidemiological studies will provide essential evidence of the overall utility of adding these markers to primary prevention efforts, screening, and clinical care.

Abstract
BACKGROUND Women with a family history of breast cancer face considerable uncertainty about whether to pursue standard screening, intensive screening, or prophylactic surgery. Accurate and individualized risk-estimation approaches may help these women make more informed decisions. Although highly penetrant genetic variants have been associated with familial breast cancer (FBC) risk, many individuals do not carry these variants, and many carriers never develop breast cancer. Common risk variants have a relatively modest effect on risk and show limited potential for predicting FBC development. As an alternative, we hypothesized that additional genomic data types, such as gene-expression levels, which can reflect genetic and epigenetic variation, could contribute to classifying a person's risk status. Specifically, we aimed to identify common patterns in gene-expression levels across individuals who develop FBC. METHODS We profiled peripheral blood mononuclear cells from women with a family history of breast cancer (with or without a germline BRCA1/2 variant) and from controls. We used the support vector machines algorithm to differentiate between patients who developed FBC and those who did not. Our study used two independent datasets, a training set of 124 women from Utah (USA) and an external validation (test) set from Ontario (Canada) of 73 women (197 total). We controlled for expression variation associated with clinical, demographic, and treatment variables as well as lymphocyte markers. RESULTS Our multigene biomarker provided accurate, individual-level estimates of FBC occurrence for the Utah cohort (AUC = 0.76 [0.67-84]) . Even at their lower confidence bounds, these accuracy estimates meet or exceed estimates from alternative approaches. Our Ontario cohort resulted in similarly high levels of accuracy (AUC = 0.73 [0.59-0.86]), thus providing external validation of our findings. Individuals deemed to have "high" risk by our model would have an estimated 2.4 times greater odds of developing familial breast cancer than individuals deemed to have "low" risk. CONCLUSIONS Together, these findings suggest that gene-expression levels in peripheral blood cells reflect genomic variation associated with breast cancer risk and that such data have potential to be used as a non-invasive biomarker for familial breast cancer risk.

Abstract
Cancer is the leading cause of death among Hispanics/Latinos, who represent the largest racial/ethnic minority group in the United States, accounting for 17.4% (55.4 million/318 million) of the total US population in 2014. Every 3 years, the American Cancer Society reports on cancer statistics for Hispanics based on incidence data from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Center for Health Statistics. Among Hispanics in 2015, there will be an estimated 125,900 new cancer cases diagnosed and 37,800 cancer deaths. For all cancers combined, Hispanics have 20% lower incidence rates and 30% lower death rates compared with non-Hispanic whites (NHWs); however, death rates are slightly higher among Hispanics during adolescence (aged 15-19 years). Hispanic cancer rates vary by country of origin and are generally lowest in Mexicans, with the exception of infection-associated cancers. Liver cancer incidence rates in Hispanic men, which are twice those in NHW men, doubled from 1992 to 2012; however, rates in men aged younger than 50 years declined by 43% since 2003, perhaps a bellwether of future trends for this highly fatal cancer. Variations in cancer risk between Hispanics and NHWs, as well as between subpopulations, are driven by differences in exposure to cancer-causing infectious agents, rates of screening, and lifestyle patterns. Strategies for reducing cancer risk in Hispanic populations include increasing the uptake of preventive services (e.g., screening and vaccination) and targeted interventions to reduce obesity, tobacco use, and alcohol consumption.

Abstract
PURPOSE Selecting optimal features from a large image feature pool remains a major challenge in developing computer-aided detection (CAD) schemes of medical images. The objective of this study is to investigate a new approach to significantly improve efficacy of image feature selection and classifier optimization in developing a CAD scheme of mammographic masses. METHODS An image dataset including 1600 regions of interest (ROIs) in which 800 are positive (depicting malignant masses) and 800 are negative (depicting CAD-generated false positive regions) was used in this study. After segmentation of each suspicious lesion by a multilayer topographic region growth algorithm, 271 features were computed in different feature categories including shape, texture, contrast, isodensity, spiculation, local topological features, as well as the features related to the presence and location of fat and calcifications. Besides computing features from the original images, the authors also computed new texture features from the dilated lesion segments. In order to select optimal features from this initial feature pool and build a highly performing classifier, the authors examined and compared four feature selection methods to optimize an artificial neural network (ANN) based classifier, namely: (1) Phased Searching with NEAT in a Time-Scaled Framework, (2) A sequential floating forward selection (SFFS) method, (3) A genetic algorithm (GA), and (4) A sequential forward selection (SFS) method. Performances of the four approaches were assessed using a tenfold cross validation method. RESULTS Among these four methods, SFFS has highest efficacy, which takes 3%-5% of computational time as compared to GA approach, and yields the highest performance level with the area under a receiver operating characteristic curve (AUC) = 0.864 ± 0.034. The results also demonstrated that except using GA, including the new texture features computed from the dilated mass segments improved the AUC results of the ANNs optimized using other three feature selection methods. In addition, among 271 features, the shape, local morphological features, fat and calcification based features were the most frequently selected features to build ANNs. CONCLUSIONS Although conventional GA is a powerful tool in optimizing classifiers used in CAD schemes of medical images, it is very computationally intensive. This study demonstrated that using a new SFFS based approach enabled to significantly improve efficacy of image feature selection for developing CAD schemes.

Abstract
Biochemical markers play a significant role in the diagnosis of lung cancer. Recent studies have demonstrated a link involving S100 Calcium Binding Proteins (S100A2, S100A6) and non-small cell lung cancer (NSCLC), but the expediency of their serum levels in NSCLC has not been established. In this study, we evaluate the potential of serum S100A2 and S100A6 levels as diagnostic markers for NSCLC. Enzyme-linked immunosorbent assay (ELISA) was performed to detect the levels of S100A2 and S100A6 in 141 NSCLC patients and 150 healthy subjects. Serum levels of the two proteins in patients with NSCLC were higher compared to healthy controls (P = 0.0002 for S100A2 and P < 0.0001 for S100A6). Moreover, the levels of S100A2 and S100A6 were higher in the sera of stage I/II NSCLC patients compared to healthy controls with P = 0.01 and <0.0001, respectively. Receiver operating characteristic (ROC) analysis showed that S100A2 could distinguish NSCLC patients from healthy controls (AUC = 0.646), and S100A6 could also identify NSCLC (AUC = 0.668). Meanwhile, these two proteins showed notable capabilities for distinguishing stage I/II NSCLC from healthy controls (AUC = 0.708 for S100A2 and AUC = 0.702 for S100A6). Our results indicate that serum levels of S100A2 and S100A6 are significantly elevated in early stage NSCLC and may have the potential for NSCLC biomarker. Further studies with large sample population would help validate our findings.

Abstract
Public perception and anxiety of familial cancer have increased demands for clinical counseling, which may be well equipped for gene testing but less prepared for counseling of the large domain of familial cancer with unknown genetic background. The aim of the present study was to highlight the full scope of familial cancer and the variable levels of risk that need to be considered. Data on the 25 most common cancers were obtained from the Swedish Family Cancer Database and a Poisson regression model was applied to estimate relative risks (RR) distinguishing between family histories of single or multiple affected first-degree relatives and their diagnostic ages. For all cancers, individual risks were significantly increased if a parent or a sibling had a concordant cancer. While the RRs were around 2.00 for most cancers, risks were up to 10-fold increased for some cancers. Familial risks were even higher when multiple relatives were affected. Although familial risks were highest at ages below 60 years, most familial cases were diagnosed at older ages. The results emphasized the value of a detailed family history as a readily available tool for individualized counseling and its preventive potential for a large domain of non-syndromatic familial cancers.

Abstract
Effective screening can reduce colorectal cancer mortality; however, screening uptake is suboptimal. Patients' stories about various health topics are widely available online and in behavioral interventions and are valued by patients. Although these narratives may be promising strategies for promoting cancer screening behavior, scant research has compared the influence of different role models. This study involving content analysis of online stories aimed to (a) describe the content of online experiential narratives about colonoscopy; (b) compare narratives from individuals who had a colonoscopy and either had colon cancer (survivors) or did not have colon cancer (screeners); and (c) generate hypotheses for future studies. The authors identified 90 narratives eligible for analysis from 15 websites. More stories were about White patients, men, and routine (vs. diagnostic) colonoscopy. A higher-than-expected number of narratives reported a family history of colorectal cancer or polyps (20%) and a colorectal cancer diagnosis (47%). Colorectal cancer survivor (vs. screener) stories were longer, mentioned symptoms and diagnostic reasons for getting a colonoscopy more often, and described the colonoscopy procedure or referred to it as easy or painless less often. Future studies should examine the effects of the role model's personal characteristics and the colonoscopy test result on reader's perceptions and intentions to have a colorectal cancer screening.

Abstract
OBJECTIVES To study the diagnostic potential of optical imaging and its comparison with colposcopy, in detecting early cervical dysplasia. METHODS The study was conducted on 200 patients attending the outdoor of UISE maternity hospital with symptoms suspicious of cervical lesions. All patients were subjected to colposcopy, followed by histo-pathological examination. Out of all HPE, 18 samples each from normal and dysplastic histology were sent to IIT Physics lab, Kanpur for optical imaging. Statistical analysis was done using sensitivity, specificity, PPV, and NPV. Chi square test was applied to calculate p value. RESULTS In optical imaging, depolarization images had shown significant changes in the epithelium region of the dysplastic tissue as compared to normal one. It is found that the mean value of depolarization power for normal cervix tissues is less than 0.32, while for dysplastic tissues it is greater than 0.32. CONCLUSION Optical imaging is fast, non-invasive tool with high sensitivity and specificity, comparable to colposcopy (sensitivity 88.9 vs 100 %, specificity 83.3 vs 86.6 %) and thus is useful in both for screening and diagnosis of cervical dysplasia.

Abstract
The purpose of this study is to develop a new global mammographic image feature analysis based computer-aided detection (CAD) scheme and evaluate its performance in detecting positive screening mammography examinations. A dataset that includes images acquired from 1896 full-field digital mammography (FFDM) screening examinations was used in this study. Among them, 812 cases were positive for cancer and 1084 were negative or benign. After segmenting the breast area, a computerized scheme was applied to compute 92 global mammographic tissue density based features on each of four mammograms of the craniocaudal (CC) and mediolateral oblique (MLO) views. After adding three existing popular risk factors (woman's age, subjectively rated mammographic density, and family breast cancer history) into the initial feature pool, we applied a sequential forward floating selection feature selection algorithm to select relevant features from the bilateral CC and MLO view images separately. The selected CC and MLO view image features were used to train two artificial neural networks (ANNs). The results were then fused by a third ANN to build a two-stage classifier to predict the likelihood of the FFDM screening examination being positive. CAD performance was tested using a ten-fold cross-validation method. The computed area under the receiver operating characteristic curve was AUC = 0.779 ± 0.025 and the odds ratio monotonically increased from 1 to 31.55 as CAD-generated detection scores increased. The study demonstrated that this new global image feature based CAD scheme had a relatively higher discriminatory power to cue the FFDM examinations with high risk of being positive, which may provide a new CAD-cueing method to assist radiologists in reading and interpreting screening mammograms.

Abstract
Background Most of the blood tests aiming for breast cancer screening rely on quantification of a single or few biomarkers. The aim of this study was to evaluate the feasibility of detecting breast cancer by analyzing the total biochemical composition of plasma as well as peripheral blood mononuclear cells (PBMCs) using infrared spectroscopy. Methods Blood was collected from 29 patients with confirmed breast cancer and 30 controls with benign or no breast tumors, undergoing screening for breast cancer. PBMCs and plasma were isolated and dried on a zinc selenide slide and measured under a Fourier transform infrared (FTIR) microscope to obtain their infrared absorption spectra. Differences in the spectra of PBMCs and plasma between the groups were analyzed as well as the specific influence of the relevant pathological characteristics of the cancer patients. Results Several bands in the FTIR spectra of both blood components significantly distinguished patients with and without cancer. Employing feature extraction with quadratic discriminant analysis, a sensitivity of ~90 % and a specificity of ~80 % for breast cancer detection was achieved. These results were confirmed by Monte Carlo cross-validation. Further analysis of the cancer group revealed an influence of several clinical parameters, such as the involvement of lymph nodes, on the infrared spectra, with each blood component affected by different parameters. Conclusion The present preliminary study suggests that FTIR spectroscopy of PBMCs and plasma is a potentially feasible and efficient tool for the early detection of breast neoplasms. An important application of our study is the distinction between benign lesions (considered as part of the non-cancer group) and malignant tumors thus reducing false positive results at screening. Furthermore, the correlation of specific spectral changes with clinical parameters of cancer patients indicates for possible contribution to diagnosis and prognosis.

Abstract
INTRODUCTION Annually, 1.4 million women worldwide are diagnosed with breast cancer (BC) and are at risk for another common malignancy: non-small-cell lung cancer (NSCLC). No large population-based study has examined subsequent survival. METHODS Women with histologically confirmed NSCLC after BC (BC-NSCLC, n = 3529) were identified in SEER-18 registries (1988-2009). Clinicopathologic characteristics and survival outcomes were compared among women with first primary NSCLC (NSCLC-1, n = 151,628). Cox regression analyses were adjusted for patient, BC, and NSCLC factors. RESULTS BC-NSCLC was diagnosed at earlier stages (34% localized, 30% regional, 36% distant) than NSCLC-1 (22%, 28%, and 50%, respectively; p < 0.0001). For localized and regional BC-NSCLC, surgical resection rates were higher than NSCLC-1 (72% versus 69% [p < 0.01] and 56% versus 46% [p < 0.0001]), respectively). Radiotherapy was given less often for BC-NSCLC than NSCLC-1 (localized: 15% versus 18%, p < 0.004; regional: 38% versus 49%, p < 0.0001). Median overall survival (OS) after localized, regional, and distant BC-NSCLC was 5.1 years, 1.9 years, and 5.8 months, respectively. For NSCLC-1, median OS was 4.6 years, 1.5 years, and 4.6 months, respectively. BC history did not affect OS for localized NSCLC, and OS was modestly greater after regional (p = 0.016) and distant (p < 0.0001) BC-NSCLC compared with NSCLC-1. BC radiotherapy to the ipsilateral chest did not unfavorably influence OS. CONCLUSIONS BC survivors are more likely to be diagnosed with earlier stage NSCLC versus first primary NSCLC patients, perhaps reflecting heightened surveillance compared with the general population. In contrast to prior studies of NSCLC in survivors of lymphopoietic malignancies, BC history does not appear to adversely affect OS after NSCLC.
