Abstract
Lung cancer is the leading cause of cancer-related mortality worldwide. Early detection is essential to achieving a better outcome and prognosis. Volatile organic compounds (VOCs) reflect alterations in the pathophysiology and body metabolism processes, as shown in various types of cancers. The biosensor platform (BSP) urine test uses animals' unique, proficient, and accurate ability to scent lung cancer VOCs. The BSP is a testing platform for the binary (negative/positive) recognition of the signature VOCs of lung cancer by trained and qualified Long-Evans rats as biosensors (BSs). The results of the current double-blind study show high accuracy in lung cancer VOC recognition, with 93% sensitivity and 91% specificity. The BSP test is safe, rapid, objective and can be performed repetitively, enabling periodic cancer monitoring as well as an aid to existing diagnostic methods. The future implementation of such urine tests as routine screening and monitoring tools has the potential to significantly increase detection rate as well as curability rates with lower healthcare expenditure. This paper offers a first instructive clinical platform utilizing VOC's in urine for detection of lung cancer using the innovative BSP to deal with the pressing need for an early lung cancer detection test tool.

Early onset metastatic colorectal cancer in patients receiving panitumumab-based upfront strategy: Overall and sex-specific outcomes in the Valentino trial. Int J Cancer 2022; 151:1760-1769.

Abstract
Anti-EGFRs plus doublet chemotherapy is considered the optimal upfront option for RAS/BRAF wild-type left-sided metastatic colorectal cancer (mCRC). Early-onset (EO) mCRC has an increasing incidence and its prognostic/predictive role and management is debatable. We performed a post hoc analysis of Valentino study, that randomized RAS wild-type mCRC patients to two panitumumab-based maintenance regimens after FOLFOX/panitumumab induction. We assessed the safety and efficacy outcomes in patients stratified for age (<50/≥50 years old). We assessed progression-free survival (PFS), overall survival (OS), response rate (ORR), rate of treatment-related and panitumumab-related adverse events (AEs) and quality of life (QoL). In 229 patients enrolled, 35 (15%) had EO mCRC, with a higher rate of female sex (P = .020) and lower rate of primary tumor resection (P = .001). Median PFS and OS were 10.9 vs 10.8 months (P = .593) and 28.1 vs 27.5 months (P = .865) in patients <50 and ≥50 years old, respectively, with no significant impact of maintenance arm. ORR and disease control rate were 74% vs 65% (P = .337) and 97% vs 81% (P = .013) in patients <50 or ≥50 years old. In younger patients, a trend for increased chemotherapy-related AEs (peculiarly anemia) was shown, while significantly decreased EGFR-related hypomagnesemia and increased skin rash were reported. No significant differences in treatment intensity or QoL were observed. In patients with EO mCRC and RAS wild-type status, we found no differences in terms of survival outcomes based on age when selecting maintenance strategies. Management of treatment-related AEs should consider the differential toxicity profile of age and sex.

A Retrospective Analysis of the Impact of HIV Infection on Outcomes of Locally Advanced Cervical Cancers Treated With Either Conventional or Hypofractionated Radiotherapy: The Uganda Experience. JCO Glob Oncol 2022; 8:e2100360. [PMID: 35696625 PMCID: PMC9225504 DOI: 10.1200/go.21.00360] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
PURPOSE We annually treat more than 800 new patients with cervical cancer, where the majority (approximately 60%) have locally advanced disease and approximately 40% of them are infected with HIV. To optimally care for this large number of patients in low-income settings is difficult. From July 2011, we started using 45.0 Gy/15# hypofractionated radiotherapy (HFRT) as a substitute to 50.0 Gy/25# conventional fractionated radiotherapy (CFRT), for the treatment of locally advanced cervical cancer (LACC). This study aims at comparing the 5-year treatment outcomes between patients with LACC, known HIV serostatus, and treated with either CFRT or HFRT. METHODS A retrospective study was conducted according to demographic/clinical data, radiotherapy fractionations, and outcomes. Factors considered were FIGO stages IIB-IIIB, known HIV serostatus, and had completed external-beam radiotherapy and intracavitary brachytherapy. The primary end point was overall survival; the secondary end points were toxicity and compliance. RESULTS The study included 221 patients. Squamous cell carcinomas were 95.1% and adenocarcinomas 2.3%. The median age was 45.0 (interquartile range, 38.0-52.0) years. Stages IIB, IIIA, and IIIB were 38.9%, 6.3%, and 54.8%, respectively. HIV-positive and HIV-negative were 87 (39.4%) and 134 (60.6%), respectively. Chemoradiation was administered in 100 (45.2%), and 52 (52.0%) completed chemotherapy. CFRT/HFRT were 116 (52.5%)/105 (47.5%). At 24 months, the overall response was 54.1% for HIV-negative compared with 45.0% for HIV-positive ( P value .262). There was no significant differences in acute/late toxicity grades ≥ 2 for HIV-negative/positive treated with HFRT/CFRT. At 60 months, the survival probabilities were 45.7% and 27.7% for HIV-negative and HIV-positive treated with CFRT ( P value = .006), whereas it was 44.2% and 30.7% for HIV-negative and HIV-positive treated with HFRT ( P value = .048), respectively. CONCLUSION For the treatment of LACC with known HIV serology, there was no significant statistical difference in terms of response, toxicity, and compliance between CFRT and HFRT. However, the difference in overall survival between HIV-negative and HIV-positive was significant.

A Comprehensive Comparison of Early-Onset and Average-Onset Colorectal Cancers. J Natl Cancer Inst 2021; 113:1683-1692. [PMID: 34405229 PMCID: PMC8634406 DOI: 10.1093/jnci/djab124] [Citation(s) in RCA: 73] [Impact Index Per Article: 24.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2021] [Revised: 03/29/2021] [Accepted: 06/04/2021] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND The causative factors for the recent increase in early-onset colorectal cancer (EO-CRC) incidence are unknown. We sought to determine if early-onset disease is clinically or genomically distinct from average-onset colorectal cancer (AO-CRC). METHODS Clinical, histopathologic, and genomic characteristics of EO-CRC patients (2014-2019), divided into age 35 years and younger and 36-49 years at diagnosis, were compared with AO-CRC (50 years and older). Patients with mismatch repair deficient tumors, CRC-related hereditary syndromes, and inflammatory bowel disease were excluded from all but the germline analysis. All statistical tests were 2-sided. RESULTS In total, 759 patients with EO-CRC (35 years, n = 151; 36-49 years, n = 608) and AO-CRC (n = 687) were included. Left-sided tumors (35 years and younger = 80.8%; 36-49 years = 83.7%; AO = 63.9%; P < .001 for both comparisons), rectal bleeding (35 years and younger = 41.1%; 36-49 years = 41.0%; AO = 25.9%; P = .001 and P < .001, respectively), and abdominal pain (35 years and younger = 37.1%; 36-49 years = 34.0%; AO = 26.8%; P = .01 and P = .005, respectively) were more common in EO-CRC. Among microsatellite stable tumors, we found no differences in histopathologic tumor characteristics. Initially, differences in TP53 and Receptor Tyrosine Kinase signaling pathway (RTK-RAS)alterations were noted by age. However, on multivariate analysis including somatic gene analysis and tumor sidedness, no statistically significant differences at the gene or pathway level were demonstrated. Among advanced microsatellite stable CRCs, chemotherapy response and survival were equivalent by age cohorts. Pathogenic germline variants were identified in 23.3% of patients 35 years and younger vs 14.1% of AO-CRC (P = .01). CONCLUSIONS EO-CRCs are more commonly left-sided and present with rectal bleeding and abdominal pain but are otherwise clinically and genomically indistinguishable from AO-CRCs. Aggressive treatment regimens based solely on the age at CRC diagnosis are not warranted.

Abstract
Cancer of the prostate are cancers in which most incidences are slow-growing, and in the U.S., a record of 1.2 million new cases of prostate cancer occurred in 2018. The rates of this type of cancer have been increasing in developing nations. The risk factors for prostate cancer include age, family history, and obesity. It is believed that the rate of prostate cancer is correlated with the Western diet. Various advances in methods of radiotherapy have contributed to lowering morbidity. Therapy for hormone- refractory prostate cancer is making progress, for almost all men with metastases will proceed to hormone-refractory prostate cancer. Smoking cigarettes along with the presence of prostate cancer has been shown to cause a higher risk of mortality in prostate cancer. The serious outcome of incontinence and erectile dysfunction result from the cancer treatment of surgery and radiation, particularly for prostate- specific antigen detected cancers that will not cause morbidity or mortality. Families of patients, as well as patients, are profoundly affected following the diagnosis of prostate cancer. Poor communication between spouses during prostate cancer increases the risk for poor adjustment to prostate cancer. The use of serum prostate-specific antigen to screen for prostate cancer has led to a greater detection, in its early stage, of this cancer. Prostate cancer is the most common malignancy in American men, accounting for more than 29% of all diagnosed cancers and about 13% of all cancer deaths. A shortened course of hormonal therapy with docetaxel following radical prostatectomy (or radiation therapy) for high-risk prostate cancer has been shown to be both safe and feasible. Patients treated with docetaxel-estramustine had a prostate-specific antigen response decline of at least 50%. Cancer vaccines are an immune-based cancer treatment that may provide the promise of a non-toxic but efficacious therapeutic alternative for cancer patients. Further studies will elucidate improved methods of detection and treatment.

Abstract
The topic of sparse representation of samples in high dimensional spaces has attracted growing interest during the past decade. In this work, we develop sparse representation-based methods for classification of clinical imaging patterns into healthy and diseased states. We propose a spatial block decomposition method to address irregularities of the approximation problem and to build an ensemble of classifiers that we expect to yield more accurate numerical solutions than conventional sparse analyses of the complete spatial domain of the images. We introduce two classification decision strategies based on maximum a posteriori probability (BBMAP), or a log likelihood function (BBLL) and an approach to adjusting the classification decision criteria. To evaluate the performance of the proposed approach we used cross-validation techniques on imaging datasets with disease class labels. We first applied the proposed approach to diagnosis of osteoporosis using bone radiographs. In this problem we assume that changes in trabecular bone connectivity can be captured by intensity patterns. The second application domain is separation of breast lesions into benign and malignant categories in mammograms. The object classes in both of these applications are not linearly separable, and the classification accuracy may depend on the lesion size in the second application. Our results indicate that the proposed integrative sparse analysis addresses the ill-posedness of the approximation problem and produces very good class separation for trabecular bone characterization and for breast lesion characterization. Our approach yields higher classification rates than conventional sparse classification and previously published convolutional neural networks (CNNs) that we fine-tuned for our datasets, or utilized for feature extraction. The BBLL technique also produced higher classification rates than learners using hand-crafted texture features, and the Bag of Keypoints, which is a sophisticated patch-based method. Furthermore, our comparative experiments showed that the BBLL function may yield more accurate classification than BBMAP, because BBLL accounts for possible estimation bias.

Abstract
Background: Colorectal cancer (CRC) is the fourth leading cause of cancer-related death in the United States, despite being largely preventable and treatable. Improving overall screening rates among both men and women is considered an important and effective strategy toward reducing morbidity and mortality from CRC. In order to optimize screening strategies, factors associated with decreased compliance need to be understood. This study aimed to compare initial CRC screening rates between males and females in a population of patients who presented for an annual physical examination. Methods: A retrospective chart review study of 380 patients designed to compare rates of initial CRC screening between males and females was conducted. Patients who were seen at our institution for an annual physical examination and were between 51 and 60 years of age were included. Results: There was no evidence of a difference in the rate of initial colon cancer screening between females (83.0%) and males (80.9%) in either unadjusted analysis (odds ratio = 1.16, P = .59) or in multivariable analysis adjusting for potential confounding variables (odds ratio = 1.16, P = .61). Conclusions: There was no significant difference in the rate of initial CRC screening between males and females who presented for an annual physical examination. This suggests that designing interventions to improve screening specific to gender may not be needed in a population of patients who attend routine preventive health examinations. Further study is needed in the general population to examine for gender-based differences in initial CRC screening among patients who do not regularly follow up for preventive examinations.

Abstract
Advances in printing materials and techniques for flexible and hybrid electronics in the domain of connected healthcare have enabled rapid development of innovative body-interfaced health monitoring systems at a tremendous pace. Thin, flexible, and stretchable biosensors that are printed on a biocompatible soft substrate provide the ability to noninvasively and unobtrusively integrate with the human body for continuous monitoring and early detection of diseases and other conditions affecting health and well being. Hybrid integration of such biosensors with extremely well-established silicon-based microcircuit chips offers a viable route for in-sensor data processing and wireless transmission in many medical and clinical settings. Here, a set of advanced and hybrid printing techniques is summarized, covering diverse aspects ranging from active electronic materials to process capability, for their use in human skin and eye-interfaced health monitoring systems with different levels of complexity. Essential components of the devices, including constituent biomaterials, structural layouts, assembly methods, and power and data processing configurations, are outlined and discussed in a categorized manner tailored to specific clinical needs. Perspectives on the benefits and challenges of these systems in basic and applied biomedical research are presented and discussed.

Abstract
Background/Aims Syndecan-2 (SDC2) methylation was previously reported as a sensitive serologic biomarker for the early detection of colorectal cancer (CRC). The purpose of this study was to investigate whether SDC2 methylation is detectable in precancerous lesions and to determine the feasibility of using SDC2 methylation for the detection of CRC and precancerous lesions in bowel lavage fluid (BLF). Methods A total of 190 BLF samples were collected from the rectum at the beginning of colonoscopy from patients with colorectal neoplasm and healthy normal individuals. Fourteen polypectomy specimens were obtained during colonoscopy. A bisulfite pyrosequencing assay and quantitative methylation-specific polymerase chain reaction were conducted to measure SDC2 methylation in tissues and BLF DNA. Results SDC2 methylation was positive in 100% of villous adenoma (VA) and high-grade dysplasia, and hyperplastic polyp samples; 88.9% of tubular adenoma samples; and 0% of normal mucosa samples. In the BLF DNA test forSDC2 methylation, the sensitivity for detecting CRC and VA was 80.0% and 64.7%, respectively, at a specificity of 88.9%. The BLF of patients with multiple tubular adenomas, single tubular adenoma and hyperplastic polyps showed 62.8%, 26.7% and 28.6% rates of methylation-positive SDC2, respectively. Conclusions Our results demonstrated that SDC2 methylation was a frequent event in precancerous lesions and showed high potential in BLF for detecting patients with colorectal neoplasm.

Abstract
Background In recent years, there has been growing concern about the overuse of colonoscopy (CC). Our objective was to evaluate the incidence rate and cumulative probability of having a potentially inadequate CC (PI-CC, e.g. a CC that was performed earlier that recommended) and the association between the report of a hyperplastic polyp in the baseline CC report and the probability of having a PI-CC. Methods A retrospective cohort of adults 50y/o or older with a complete baseline CC between January 1st and December 31st 2005, without reported lesions or with hyperplastic polyps, based on secondary data extracted from the electronic medical record of the Hospital Italiano of Buenos Aires. The outcome consisted of time until a PI-CC, defined as the time measured between basal colonoscopy and a colonoscopy performed earlier than the inter-screening interval recommended by the USPSTF and the USMSTF. Results 389 patients were included. The cumulative probability of receiving a PI-CC over 10 years was 0.29 (95% CI 0.241, 0.342). The incidence rate resulted in 30.91 PI-CC per 1000 person-years (95% CI 25.14, 38). The crude analysis of the association between the outcome and the presence of hyperplastic polyps in the baseline CC, showed a statistically significant difference between both groups (log rank, p 0.036). The multivariate analysis yielded a hazard ratio of 1.67 (95% CI 1.02–2.73). Conclusion We observed that 3 in every 10 patients treated in our health system received a PI-CC during the first ten consecutive years after a normal complete CC. Furthermore, this could be in part attributed to the presence of a hyperplastic polyp in the baseline CC.

Abstract
The identification of some types of human papillomavirus (HPV) as necessary, but not sufficient, cause of cervical cancer has suggested the use of HPV testing in cervical cancer prevention. A large number of studies has provided evidence supporting its application (1) as primary screening test, (2) for triaging borderline cytology, (3) for follow-up after positive primary test but no abnormal histology and (4) as a test of cure. They also allowed a reasonably good definition of the appropriate policies and protocols, leading to the delivery of evidence-based guidelines resulting from a systematic review of the literature. In this chapter, we present a critical analysis of the recommendations of the main European and North American guidelines relative to industrialised countries.

Abstract
Colorectal cancer screening is one of the few cancer screenings with an "A" rating from the US Preventive Services Task Force, meaning that the procedure confers a substantial health benefit. However, 40 percent of people who should receive colorectal cancer screenings do not receive them. Colonoscopies are the most thorough method of screening because they allow physicians to view the entire length of the colon and remove polyps as needed. Billing methods that distinguish between screening and therapeutic procedures have kept expected colonoscopy costs high. However, the Affordable Care Act partially closed the so-called colonoscopy loophole and reduced expected out-of-pocket expenses for all Medicare beneficiaries. Using data from the Behavioral Risk Factor Surveillance System, we found that annual colonoscopy rates among men ages 66-75 increased significantly (by 4.0 percentage points) after the Affordable Care Act policy change, and we found some evidence of even larger increases among socioeconomically disadvantaged men. We found no significant increases among women, a result that may be explained by health behavior and other factors and that requires further study. Our research indicates that cost may be an important barrier to colorectal cancer screening, at least among men, and that making further policy changes to close remaining loopholes may improve screening rates.

Abstract
BACKGROUND Breast cancer is a leading cause of cancer death among Hispanic women in the U.S., and mammography is the recommended screening for early diagnosing and preventing breast cancer. Several barriers exist to influence mammography utilization including poor health literacy. However, it is unclear whether the effect of health literacy on mammography utilization is consistent between Hispanic women and non-Hispanic White women. The main objective of this study was to examine association between functional health literacy and the receipt of mammography among Hispanic women compared to non-Hispanic White women in the U.S. METHODS A cross-sectional design using participants engaged in the National Assessment of Adult Literacy. Study sample comprised of 4,249 Hispanic and non-Hispanic U.S.-born White women ≥ 40 years of age who completed the functional health literacy assessment. Regression analyses were performed to test the association between health literacy and receipt of mammography. Among Hispanic women, analyses considered the influence of language-preference acculturation. RESULTS Equal percentages of Hispanic (59.3%) and non-Hispanic White (60.6%) women received mammography. After adjusting for covariates, health literacy was positively associated with receiving mammography among U.S.-born White women (β = 0.14, p<0.001), but negatively associated with mammography among Hispanic women (β = -0.13, p<0.001). Analyses stratified by acculturation status revealed that higher health literacy was associated with lower mammography among language-preference acculturated Hispanic women (β = -0.48, p<0.001), yet an opposite result among less acculturated Hispanic women (β = 0.08, p<0.001). CONCLUSION Functional health literacy has different associations with mammography depending upon ethnicity. Language-preference acculturation may explain the differing association.

Abstract
Regular screening is considered the most effective method to reduce the mortality and morbidity associated with breast cancer. Nevertheless, contradictory evidence about screening mammograms has led to periodic changes and considerable variations among different screening guidelines. This study is the first to examine the immediate impact of the 2009 US Preventive Services Task Force (USPSTF) guideline modification on physician recommendation of mammograms. The study included visits by women aged 40 years and older without prior breast cancer from the National Ambulatory and Medical Care Survey 2008-2010. Bivariate and multiple logistic regressions were used to determine the factors associated with mammography recommendation. Approximately 29,395 visits were included and mammography was recommended during 1350 visits; 50-64-year-old women had 72% higher odds, and 65-74-year-old women had twice the odds of getting a mammogram recommendation compared with 40-49-year-old women in 2009. However, there was no difference in recommendation by age groups in 2008 and 2010. Obstetricians and gynecologists did not modify their recommendation behavior in 2009, unlike all other specialists who reduced their recommendation for 40-49-year-old women in 2009. Other characteristics associated with mammogram recommendations were certain patient comorbidities, physician specialty and primary care physician status, health maintenance organization status of the clinic, and certain visit characteristics. This study demonstrated a temporary effect of the USPSTF screening guideline change on mammogram recommendation. However, in light of conflicting recommendations by different guidelines, the physicians erred toward the more rigorous guidelines and did not permanently reduce their mammogram recommendation for women aged 40-49 years.

Abstract
Background: The predicted increase in incidence of oral cavity cancer (OCC) coupled with high mortality and poor prognosis – particularly when diagnosed at a late/advanced stage – highlights the need for prevention and early detection/screening to reverse these trends. Dental healthcare professionals in primary care settings have a pivotal role in this effort. Aim: The aim of this protocol is to detail the process for assessing the evidence for the best practice and methods of early detection/screening for OCC in primary care dental settings by undertaking a systematic review of global clinical guidelines and published systematic reviews. Method: Searches for clinical guidelines and systematic reviews will be conducted in the following databases: Cochrane library, Medical Literature Analysis and Retrieval System Online (Ovid), Excerpta Medical dataBASE, PubMed, Turning Research into Practice, SCOPUS and Web of Science Core Collection. Our search will extend to include Google Scholar and international professional organizations/associations websites. In addition, we will handsearch the bibliographies and undertake citation searches of the selected papers. Quality appraisal will be undertaken using the Appraisal of Guidelines for Research and Evaluation version II instrument for the clinical guidelines and both A MeaSurement Tool to Assess Systematic Reviews and Risk of Bias in Systematic Reviews tools for the systematic reviews. A narrative synthesis approach will be used to assess the evidence of extracted data, primarily taking account of quality appraisal and recency of publication. Discussion: The synthesis of evidence will determine best practice for OCC early detection/screening by primary care dental healthcare professionals and will evaluate the relationship between clinical guidelines and the evidence base available from systematic reviews in this area.

Abstract
Objectives To assess the diagnostic value of dual energy spectral CT imaging for colorectal cancer grading using the quantitative iodine density measurements in both arterial phase (AP) and venous phase (VP). Methods 81 colorectal cancer patients were divided into two groups based on their pathological findings: a low grade group including well (n = 13) and moderately differentiated cancer (n = 24), and a high grade group including poorly differentiated (n = 42) and signet ring cell cancer (n = 2). Iodine density (ID) in the lesions was derived from the iodine-based material decomposition (MD) image and normalized to that in the psoas muscle to obtain normalized iodine density (NID). The difference in ID and NID between AP and VP was calculated. Results The ID and NID values of the low grade cancer group were, 14.65±3.38mg/mL and 1.70±0.33 in AP, and 21.90±3.11mg/mL and 2.05± 0.32 in VP, respectively. The ID and NID values for the high grade cancer group were 20.63±3.72mg/mL and 2.95±0.72 in AP, and 26.27±3.10mg/mL and 3.51±1.12 in VP, respectively. There was significant difference for ID and NID between the low grade and high grade cancer groups in both AP and VP (all p<0.001). ROC analysis indicated that NID of 1.92 in AP provided 70.3% sensitivity and 97.7% specificity in differentiating low grade cancer from high grade cancer. Conclusions The quantitative measurement of iodine density in AP and VP can provide useful information to differentiate low grade colorectal cancer from high grade colorectal cancer with NID in AP providing the greatest diagnostic value.

Abstract
Objective: The aim of this study was to determine the awareness about skin cancer, prevention, and early detection among university students. Methods: This descriptive cross-sectional study was carried out with 404 students in a university located in Ankara, the capital city of Turkey. A 35-item questionnaire was used for data collection. Results: Less than half of the students (37.9%) had knowledge about skin cancer mostly through the internet (24.5%) and media (24.1%). Half of them aware of the risk factors; mostly as avoiding direct exposure to the Sun between 10 am and 4 pm (45.3%); smoking and alcohol (38.4%); having fair skin color (34.9%); and ultraviolet light exposure (25.7%). Only one-third of them (32.9%) are knowledgeable about skin cancer signs and symptoms, such as a change in color and appearance of the nevus/moles (24%). The majority of the responders (77.3%) did not know about screening tests for skin cancer and only 18 (4.5%) students were practicing skin self-examination. Conclusions: This study showed a lack of knowledge about skin cancer, prevention, and early detection among university students and reported the need for educational interventions to raise awareness in this target group.

Abstract
Endometrial cancer is the sixth most common cancer in women. Galectin-3 (GAL-3) and CRIP-1 are multifunctional proteins which seem to be involved in many neoplasias. This study aims to point out correlations between clinicopathological findings and endometrial cancer patient survival to GAL-3 and CRIP-1 expression in order to enfold their diagnostic/prognostic potential. Tissues from 46 patients diagnosed with endometrial cancer were studied by immunohistochemistry, using monoclonal antibodies for GAL-3 and CRIP-1, and expression levels were correlated with clinicopathological findings and survival. Analysis was performed at single protein level or as co-expression. High expression of GAL-3 and CRIP-1 was independently associated with tumor depth and histological grade, respectively. Also, there was a significant correlation between high co-expression of the two proteins and the histological grade (aOR 2.66), the tumor depth (aOR 0.32) and the histological type (aOR 1.32), but not with the patients' age. Moreover, high expression of both proteins was observed in patients with shorter survival times. Interestingly, the co-expression of the two proteins exhibited some degree of monotony (Spearman's ρ = 0.768), indicating a common molecular pathway. This study provides evidence for a prognostic clinical potential of the combined study of GAL-3 and CRIP-1 in endometrial cancer. These factors are poorly studied in endometrium, and their role in the carcinogenetic process and on effective therapy awaits further elucidation.

Abstract
Background: Prostate cancer is the most common cancer among Nigerian men and the second most common cause of death from cancer in men worldwide. The aim of this study was to assess the level of awareness of prostate cancer among men attending the various outpatients’ clinics of the Lagos State University Teaching Hospital, Ikeja. Materials and Methods: This study is a descriptive cross-sectional study. Self-administered structured questionnaires were used to collect information from consecutives patients attending the various outpatient clinics of the hospital. Results: One hundred and forty-six respondents with an age range of 40–80 years participated in this study. Sixty-nine (47.3%) respondents were aware of prostate cancer while 77 (52.7%) have never heard of the disease. Twenty (13.7%) participants were aware of the availability of a screening test for the disease and only 12 (8.2%) have had any form of screening for prostate cancer. Conclusion: There is a low level of awareness of prostate cancer among patients seen at our center and also level of voluntary screening for the disease is low.

SALL4 as an Epithelial-Mesenchymal Transition and Drug Resistance Inducer through the Regulation of c-Myc in Endometrial Cancer. PLoS One 2015; 10:e0138515.

Abstract
SALL4 plays important roles in the development and progression of many cancers. However, the role and molecular mechanism of SALL4 in endometrial cancer remain elusive. In the present research, we have demonstrated that the expression of SALL4 was upregulated in endometrial cancer and correlated positively with tumor stage, metastases and poor survival of patients. The overexpression of SALL4 promoted the invasiveness in endometrial cancer cells, as indicated by the upregulation of mesenchymal cell marker N-cadherin and downregulation of the epithelial marker E-cadherin, and invasion assays in vitro. Additionally, there was also an increase in drug resistance in these cell models due to the upregulation of ATP-binding cassette multidrug transporter ABCB1 expression. Moreover, we also found that ABCB1 was critical for SALL4-induced drug resistance. In contrast, SALL4 knockdown restored drug sensitivity, reversed EMT, diminished cell metastasis and suppressed the downregulation of E-cadherin and the upregulation of N-cadherin and ABCB1. Furthermore, we showed that SALL4 upregulated c-Myc expression and c-Myc was a direct target for SALL4 by ChIP assay, depletion of c-Myc with siRNA abolished the SALL4-induced downregulation of E-cadherin, upregulation of N-cadherin and ABCB1, suggesting that c-Myc was a downstream target for SALL4 and required for SALL4-induced EMT, invasion and drugs resistance in endometrial cancer cells. These results indicated that SALL4 could induce EMT and resistance to antineoplastic drugs through the regulation of c-Myc. SALL4 and c-Myc may be novel therapeutic targets for endometrial cancer.

Abstract
Proteomics and metabolomics investigations of body fluids present several challenges for biomarker discovery of several diseases. The search for biomarkers is actually conducted in different body fluids, even if the ideal biomarker can be found in an easily accessible biological fluid, because, if validated, the biomarker could be sought in the healthy population. In this regard, tears could be considered an optimum material obtained by noninvasive procedures. In the past years, the scientific community has become more interested in the study of tears for the research of new biomarkers not only for ocular diseases. In this review, we provide a discussion on the current state of biomarkers research in tears and their relevance for clinical practice, and report the main results of clinical proteomics studies on systemic and eye diseases. We summarize the main methods for tear samples analyses and report recent advances in "omics" platforms for tears investigations. Moreover, we want to take stock of the emerging field of metabolomics and lipidomics as a new and integrated approach to study protein-metabolites interplay for biomarkers research, where tears represent a still unexplored and attractive field.

Abstract
BACKGROUND The aim of the present study was to investigate perceived inhibiting and facilitating factors concerning cervical cancer early diagnosis behavior in Turkish women over the age of 40. MATERIALS AND METHODS The study was carried out by qualitative focus group interview with 35 participating women, in the period between April-June 2010. A semi-structured interview questionnaire based on the Health Belief Model and the Health Promotion Model was used. Content analysis was applied to the study data. RESULTS Barriers such as lack of knowledge of women as regards to the cervical cancer and early detection, lack of sensitivity- negligence, forgetting, fear, inadequacy of health insurance and transportation, financial problems, inability to get an appointment, lack of female doctors, embarrassment, fatalist approach were frequently addressed. As for facilitating factors, these included provision of information, health professionals showing interest and tolerance, free services, provision of transportation means and reminding telephone calls. CONCLUSIONS Focus group interviews were found to be effective in determining inhibiting and facilitating factors concerning cervical cancer early diagnosis behavior. In line with the results of the study, preparation of structured national and regional education programs and their addition to curriculum programs may be effective in realizing and maintaining positive early detection behavior.

Abstract
The scope of the applications of breath sensors is abundant in disease diagnosis. Lung cancer diagnosis is a well-fitting health-related application of this technology, which is of utmost importance in the health sector, because lung cancer has the highest death rate among all cancer types, and it brings a high yearly global burden. The aim of this review is first to provide a rational basis for the development of breath sensors for lung cancer diagnostics from a historical perspective, which will facilitate the transfer of the idea into the rapidly evolving sensors field. Following examples with diagnostic applications include colorimetric, composite, carbon nanotube, gold nanoparticle-based, and surface acoustic wave sensor arrays. These select sensor applications are widened by the state-of-the-art developments in the sensors field. Coping with sampling sourced artifacts and cancer staging are among the debated topics, along with the other concerns like proteomics approaches and biomimetic media utilization, feature selection for data classification, and commercialization.

Abstract
The survival rate of lung cancer can be significantly improved by monitoring biomarkers in exhaled air that indicate diseases in early stage, so it is very important to develop micro analytical systems which can offer a fast, on-site, real-time detecting biomarkers in exhaled air. In this paper, a mini-gas chromatography (GC)-photo-ionization detector (PID) system integrated with a micro GC column and a micro pre-concentrator was developed for forming an inexpensive, fast, and non-invasive diagnostic tool for lung cancer. This system has very strong concentrate ability owing to its integrated micro pre-concentrator, which make the detection of trace components in exhaled air very easy. In addition, the integrated micro GC column can separate complex mixtures, which overcome low resolution and poor anti-interference ability of other instruments. The results indicated that the mini-GC-PID system can effectively separate and detect the biomarkers at parts-per-billion (ppb) level.

Abstract
OBJECTIVE To determine whether different utilities for prostate cancer screening outcomes for couples, and husbands and wives separately, lead to incongruent screening recommendations. METHODS We evaluated survey results of 168 married couples from three family practice centers in Texas, USA. Utilities for eight adverse outcomes of prostate cancer screening and treatment were assessed using the time trade-off method. We assessed utilities separately for each partner and jointly for each couple. Using a previously published decision-analytic model of prostate cancer screening, we input the husband's age (starting point) and utilities for outcomes from the husband's, wife's, and couple's perspectives (to adjust for quality of life). Both group-level and individualized models were run. We also asked husbands (and wives) if they intended to be screened (or have their husbands screened) for prostate cancer in the future. RESULTS Husbands' lower tolerance for adverse outcomes (lower utilities) was associated with lower quality-adjusted life expectancy (than their wives) for the choice of screening versus not screening. Depending on the perspective, 48 husbands (28.6%), 89 wives (53.0%), and 58 couples (34.5%) preferred screening in the individual decision-analytic models. Comparing the three perspectives, agreement in model recommendations was greatest between the husbands and the couples (82.1%), intermediate between the wives and couples (63.7%), and lowest between the husbands and wives (55.4%). Using group-aggregated utilities in the decision-analytic model tended to mask the variation in recommended strategies amongst individuals. There was no relationship between screening preferences from the model and the husbands' and wives' reported desire for screening, as the majority of subjects wanted screening. CONCLUSIONS Discordant health preferences may yield conflicting recommendations for prostate cancer screening. The results have broad implications for informed healthcare decision making for couples.

Abstract
Women afflicted by the hereditary breast and ovarian cancer syndrome face complex decisions regarding medical interventions aimed at reducing their risk of ovarian and breast cancer, interventions which in turn may interfere with their fertility and cause early menopause. This review addresses selected topics of importance and controversy in the management of the BRCA mutation carrier, such as psychological well-being and quality of life, breast and ovarian cancer screening, risk-reducing interventions for breast cancer and ovarian cancer, the issue of hysterectomy at the time of the risk-reducing salpingo-oophorectomy, health consequences of early surgical menopause, and safety of hormonal therapy after oophorectomy. The information presented is based on an extensive review of the literature on the selected topics and on the expertise of our multidisciplinary team.

Abstract
INTRODUCTION Prostate cancer (CaP) is the most commonly diagnosed cancer among Nigerian men but CaP screening is not a common practice. The true burden of the disease in Nigeria is not known. The study was aimed at studying the community burden of CaP in Lagos. METHODS During a community-based prostate cancer awareness program in 13 local government areas of Lagos, men aged >40 years had serum total PSA (tPSA) test and digital rectal examination (DRE). Those with abnormal DRE or tPSA >95th percentile of the cohort or both were selected for prostate biopsy (TRPB). RESULTS 4172 men were screened and complete data was available for 4110 (98.5%). The mean age was 60.8 years. DRE was abnormal in 410 men and was significantly correlated with the age of the patient and tPSA (p<0.001). The tPSA ranged from 0 to 438.3 ng/ml with a median, mean and 95th percentile of 1.5, 2.5 and 10.0 ng/ml respectively. 341 out of the 438 (78%) men selected were subjected to TRBP. Forty-three men had histological diagnosis of CaP, giving an estimated prevalence rate of at least 1.046% or 1046 per 100,000 men of age ≥40. Only 11 (26%) had organ-confined disease while 17 (40%) had locally advanced disease and 15 (35%) men had metastatic disease. The majority of the men, 32 (74%) were reported to have Gleason's score of ≥7. CONCLUSION The prevalence rate of CaP among men aged ≥40 years in Lagos is higher than previously reported in hospital-based study. Majority have advanced and high-grade disease.

Abstract
Little is known about the extent to which evidence-based prevention topics are taught in medical school. All class of 2003 medical students (n = 2316) at 16 US schools were eligible to complete three questionnaires: at the beginning of first and third years and in their senior year, with 80.3% responding. We queried these students about 21 preventive medicine topics, concerning the extent of their training and their patient counseling frequency at some of these time points. At the beginning of the third year, self-reported extensive training was low for all preventive medicine topics (range 7-26%). USPSTF-recommended topics received more curricular time (median for topics: 36% if recommended versus 24.5% if not, P = 0.025), as did topics addressed through testing rather than through discussion (median for topics: 37% for testing and 25% for discussion, P = 0.005). Extensive training was always associated with higher counseling frequency, and intention to go into primary care, female gender, a positive attitude toward prevention and positive personal health habits were associated with higher counseling frequency. Although some bemoan the overall low levels of US medical students' prevention-related training and practice, we demonstrate that at least they are preferentially evidence-based, a novel and encouraging finding for preventionists.

Abstract
A biomarker is a quantifiable laboratory measure of a disease specific biologically relevant molecule that can act as an indicator of a current or future disease state. The purpose of this study is to detect the expression of RNA biomarkers using Cytokeratin 19 (CK-19), Mammaglobin (MAM), Carcinoembryonic antigen (CEA), Mucin (MUC), C-Myc, erb-B2, a proliferation marker (Ki-67), Epidermal growth factor receptor (Her2/neu) and Estrogen receptor (ER) in Iranian women who were diagnosed with breast cancer. In this study, 90 samples; 60 cancer patients and 30 healthy controls were considered. 73.4 % patients were in stage I/II and 26.6 % were in stage III/IV. Patients were selected prior to the administration of any adjuvant systemic therapy. Total RNA extraction was obtained from peripheral blood of each patient and healthy control. Reverse transcription polymerase chain reaction (RT-PCR) method was used for detection of mRNA of the selected biomarkers of circulating breast cancer cells in blood. Molecular characterization is assessed as a method for early detection of breast cancer. For this purpose, eleven specific primers were selected and RT-PCR was used. The data of RT-PCR revealed that expression of MUC1, CK19, CEA, MAM, erbB-2, Ki67 and C-Myc biomarkers were significantly different between breast cancer patients and healthy controls. On the other hand, ERα, ERβ and Her2 markers were not significantly different between the two mentioned groups. Biomarkers detection of breast cancer patients could be assessed as a diagnostic factor and its potential for conveying as a prognostic factor require further studies, with a larger number of patients.

Abstract
Colorectal cancer is the second most common cancer in males and the fourth most common in females in Korea. Since the most of colorectal cancer occur through the prolonged transformation of adenomas into carcinomas, early detection and removal of colorectal adenomas are one of the most effective methods to prevent colorectal cancer. Considering the increasing incidence of colorectal cancer and polyps in Korea, it is very important to establish Korean guideline for colorectal cancer screening and polyp detection. Korean Multi-Society Take Force developed the guidelines with evidence-based methods. Parts of the statements drawn by systematic reviews and meta-analyses. Herein we discussed the epidemiology of colorectal cancers and adenomas in Korea, optimal screening methods for colorectal cancer, and detection for adenomas including fecal occult blood tests, radiologic tests, and endoscopic examinations.

BACKGROUND Although guidelines recommend against prostate-specific antigen (PSA) screening in elderly men with limited life expectancy, screening is common. OBJECTIVE We sought to identify medical center characteristics associated with screening in this population. DESIGN/PARTICIPANTS We conducted a prospective study of 622,262 screen-eligible men aged 70+ seen at 104 VA medical centers in 2003. MAIN MEASURES Primary outcome was the percentage of men at each center who received PSA screening in 2003, based on VA data and Medicare claims. Men were stratified into life expectancy groups ranging from favorable (age 70-79 with Charlson score = 0) to limited (age 85+ with Charlson score ≥1 or age 70+ with Charlson score ≥4). Medical center characteristics were obtained from the 1999-2000 VA Survey of Primary Care Practices and publicly available VA data sources. KEY RESULTS Among 123,223 (20%) men with limited life expectancy, 45% received PSA screening in 2003. Across 104 VAs, the PSA screening rate among men with limited life expectancy ranged from 25-79% (median 43%). Higher screening was associated with the following center characteristics: no academic affiliation (50% vs. 43%, adjusted RR = 1.14, 95% CI 1.04-1.25), a ratio of midlevel providers to physicians ≥3:4 (55% vs. 45%, adjusted RR = 1.20, 95% CI 1.09-1.32) and location in the South (49% vs. 39% in the West, adjusted RR = 1.25, 95% CI 1.12-1.40). Use of incentives and high scores on performance measures were not independently associated with screening. Within centers, the percentages of men screened with limited and favorable life expectancies were highly correlated (r = 0.90). CONCLUSIONS Substantial practice variation exists for PSA screening in older men with limited life expectancy across VAs. The high center-specific correlation of screening among men with limited and favorable life expectancies indicates that PSA screening is poorly targeted according to life expectancy.

Abstract
Now colorectal cancer is the second most common cancer in males and the fourth most common cancer in females in Korea. Since most of colorectal cancers occur after the prolonged transformation of adenomas into carcinomas, early detection and removal of colorectal adenomas are one of the most effective methods to prevent colorectal cancer. Considering the increasing incidence of colorectal cancer and polyps in Korea, it is very important to establish Korean guideline for colorectal cancer screening and polyp detection. The guideline was developed by the Korean Multi-Society Take Force and we tried to establish the guideline by evidence-based methods. Parts of the statements were draw by systematic reviews and meta-analyses. Herein we discussed epidemiology of colorectal cancers and adenomas in Korea and optimal methods for screening of colorectal cancer and detection of adenomas including fecal occult blood tests, radiologic tests, and endoscopic examinations.

Abstract
Current American Society of Colposcopy and Cervical Pathology recommendations about human papillomavirus (HPV) triage and further management for atypical squamous cells are pertinent to cervical Papanicolaou (Pap) tests. There are limited data on HPV detection in vaginal liquid-based cytology (LBC) specimens. The aims of this study were to determine whether adjunctive high-risk (HR)-HPV testing is useful for disease risk assessment in women with vaginal atypical squamous cells of undetermined significance (ASC-US) and atypical squamous cells, cannot exclude HSIL (ASC-H) Pap results. We identified 1,125 ASC-US and 36 ASC-H vaginal Pap results with HR-HPV testing. Of the cases, 244 (21.7%) ASC-US and 21 (58%) ASC-H were HR-HPV+. Among ASC-US HR-HPV+ cases, 47.8% had a squamous intraepithelial lesion (SIL) compared with 4.7% of HR-HPV- cases. Among ASC-H HR-HPV+ cases, 75% (12/16) had SIL compared with 31% (4/13) in HR-HPV- cases. Our results indicate that HPV triage testing is a reasonable and cost-effective approach for women with ASC-US vaginal Pap results and also a useful option for women with ASC-H vaginal Pap results.

Abstract
BACKGROUND To date there has not been any nationwide age-standardized incidence data reported for prostate cancer in Nigeria. We examined and integrated diverse trends in the age-specific incidence of prostate cancer into a comprehensive trend for Nigeria, and examined how best the existing data could generate a countrywide age-standardized incidence rate for the disease. METHODS Data were obtained from studies undertaken between 1970 and 2007 in referral hospital-based cancer registries. Records from at least one tertiary hospital in each of the six geopolitical zones of Nigeria were examined retrospectively. Data were also reported for the rural population in cross-sectional prospective studies. Age-standardized incidence rates and the annual incidence of disease were calculated. RESULTS Higher incidence rates for prostate cancer during this period were recorded for patients aged 60-69 years and 70-79 years, with a lower incidence rate for patients aged younger than 50 years. An exponential annual incidence rate of disease was observed in the 50-79 year age group and peaked at 70-79 years before dropping again at age 80 years. The results showed metastasis in more than half of these hospital-based prostate tumors. CONCLUSION Our results suggest that prostate cancer occurs at a relatively young age in Nigerians and that hospital-based registry reports may not appropriately reflect the incidence of the disease in Nigeria. A countrywide screening program is urgently needed. Finally, the difference in reported stages of disease found in Nigerians and African-Americans versus Caucasians suggests biological differences in the prognosis. Nigeria may thus typify one of the ancestral populations that harbor inherited genes predisposing African-Americans to high-risk prostate cancer.

Abstract
Diagnosing breast cancer early and efficiently is a critical component of any strategy aimed at decreasing breast cancer mortality in developing countries. In this chapter, I evaluate the evidence behind screening strategies and its controversies. The effect of breast-cancer screening has never been formally evaluated in developing countries, and data from the major screening trials need to be viewed in this context. Screening asymptomatic women by means of breast self-examination, clinical examination or mammography can play a significant role in decreasing breast-cancer mortality in developing countries. Major programmes should not be implemented, however, until adequate diagnostic and therapeutic facilities are in place. The most fundamental interventions in early detection, diagnosis, surgery, radiation therapy, and drug therapy must be integrated, organised and resourced appropriately within existing healthcare structures.

Abstract
BACKGROUND Cosmetic breast surgery is amongst the top five most commonly performed cosmetic surgical procedures. With breast cancer being the most common non-skin malignancy in women, the likelihood that a woman undergoing cosmetic breast surgery may have an occult breast cancer needs to be considered. Most of the available data pertaining to breast cancer diagnosis in the setting of cosmetic surgery are from studies of cosmetic breast surgery populations. We report on the prevalence of breast cancer as an incidental finding during cosmetic breast surgery in the context of women subsequently diagnosed with invasive breast cancer. METHODS The Bupa Health Foundation Health and Wellbeing after Breast Cancer Study is a prospective cohort study of 1684 women recruited within 12 months of their first diagnosis with invasive breast cancer. Participants completed an enrolment questionnaire and annual follow-up questionnaires for 5 years. RESULTS At the second follow-up, 1.5% of women reported having undergone cosmetic breast surgery prior to being diagnosed with breast cancer, 16 had undergone breast reduction and seven had augmentations. Invasive breast cancer was diagnosed at the time of a cosmetic breast procedure in two women, in both an augmentation and a reduction procedure, which is 8.7% (95% confidence interval 23.5% to +20.9%) of the women in our study reporting a cosmetic breast procedure prior to diagnosis. CONCLUSIONS Although prior cosmetic breast surgery was reported by few women, breast cancer was diagnosed in two women during the procedure. Surgeons performing elective breast surgery need to understand and apply consistent, reliable breast cancer screening practices.

Abstract
BACKGROUND Some have recommended against routine screening for colorectal cancer (CRC) among patients ≥75 years of age, while others have suggested that screening colonoscopy (SC) is less beneficial for women than men. We estimated the expected benefits (decreased mortality from CRC) and harms (SC-related mortality) of SC based on sex, age, and comorbidity. OBJECTIVE To stratify older patients according to expected benefits and harms of SC based on sex, age, and comorbidity. DESIGN Retrospective study using Medicare claims data. PARTICIPANTS Medicare beneficiaries 67-94 years old with and without CRC. MAIN MEASURES Life expectancy, CRC- and colonoscopy-attributable mortality rates across strata of sex, age, and comorbidity, pay-off time (i.e. the minimum time until benefits from SC exceeded harms), and life-years saved for every 100,000 SC. KEY RESULTS Increasing age and comorbidity were associated with lower CRC-attributable mortality. Due to shorter life expectancy and CRC-attributable mortality, the benefits associated with SC were substantially lower among patients with greater comorbidity. Among men aged 75-79 years with no comorbidity, the number of life-years saved was 459 per 100,000 SC, while men aged 67-69 with ≥3 comorbidities had 81 life-years saved per 100,000 SC. There was no evidence that SC was less effective in women. Among men and women 75-79 with no comorbidity, number of life-years saved was 459 and 509 per 100,000 SC, respectively; among patients with ≥3 comorbidities, there was no benefit for either men or women. CONCLUSIONS Although the effectiveness of SC was equivalent for men and women, there was substantial variation in SC effectiveness within age groups, arguing against screening recommendations based solely on age.

Abstract
OBJECTIVE The significance of high-risk HPV (hrHPV) testing in the management of women with abnormal cervical Pap tests is well known. However, the data about the hrHPV detection and its significance in abnormal vaginal specimens are very limited. The purpose of this study was to assess the prevalence of hrHPV in women with abnormal vaginal smears. METHODS Our Copath database system was searched to retrieve all the vaginal Pap tests with adjunctive HC2 hrHPV DNA test performed between July 1, 2005, and July 30, 2009. The results of hrHPV were reviewed in different TBS 2001 categories, in different age groups, and in white and African American women. RESULTS During the study period, there were 1,320 vaginal ThinPrep Pap tests with adjunctive HC2 hrHPV, reported as atypical squamous cells of undetermined significance (n = 1,125), atypical squamous cells cannot rule out high grade (n = 36), low-grade squamous intraepithelial lesion (n = 148), and high-grade squamous intraepithelial lesion (n = 11). A positive hrHPV DNA result was obtained in a total of 387 cases (29.3%), which included 244 atypical squamous cells of undetermined significance (21.7%), 21 atypical squamous cells cannot rule out high-grade (58.3%), 113 low-grade squamous intraepithelial lesion (76.4%), and 9 high-grade squamous intraepithelial lesions (81.8%). Mean age was 56.5 years (range = 17-93 y). High-risk HPV-positive rate was 34.5% versus 24.9% in women aged 54 years or younger compared with those aged ≥ 55 years or older (p < .001) and 45.1% versus 27.3% in African American women compared with white women (p < .001). High-risk HPV DNA-positive rate was 2.6% among the 1,572 women with negative vaginal Pap tests. CONCLUSIONS Our results show that prevalence of hrHPV in abnormal vaginal smears parallels that of cervical smears with equivalent degree of abnormality. The suggestion of reflex hrHPV testing as a tool in formulating the management plan for women with abnormal vaginal smears needs further attention.

Abstract
Immunochemical fecal occult blood test (FIT) is a new colorectal cancer (CRC) screening method already recommended by the American screening guidelines. We aimed to test the feasibility of FIT as compared to guaiac fecal occult blood test (G-FOBT) in a large urban population of Tel Aviv. Average-risk persons, aged 50-75 years, were offered FIT or G-FOBT after randomization according to the socioeconomic status of their clinics. Participants with positive tests underwent colonoscopy. Participants were followed through the Cancer Registry 2 years after the study. Hemoccult SENSA™ and OC-MICRO™ (three samples, 70 ng/ml threshold) were used. FIT was offered to 4,657 persons (Group A) and G-FOBT to 7,880 persons (Group B). Participation rate was 25.9% and 28.8% in Group A and B, respectively (p < 0.001). Positivity rate in Group A and B was 12.7% and 3.9%, respectively (p < 0.001). Cancer found in six (0.49%) and eight (0.35%) patients of Group A and B, respectively (NS). Cancer registry follow-up found missed cancer in five (0.22%) cases of Group B and none in Group A (NS). The sensitivity, specificity, negative and positive predictive value for cancer in Group A and B were 100%, 85.9%, 100%, 3.9% and 61.5%, 96.4%, 99.8%, 9.1%, respectively. There was increased detection of advanced adenomatous polyp (AAP) by FIT, irrespective of age, gender, and socioeconomic status (Per Protocol: odds ratio 2.69, 95% confidence interval 1.6-4.5; Intention to Screen: odds ratio 3.16, 95% confidence interval 1.8-5.4). FIT is feasible in urban, average-risk population, which significantly improved performance for detection of AAP and CRC, despite reduced participation.

Abstract
Background The lack of adequate randomized clinical trials (RCT) has hindered identification of new therapies that are safe and effective for patients with primary focal segmental glomerulosclerosis (FSGS), especially in patients who fail to respond to corticosteroids and immunosuppressive therapies. Recent basic science advances have led to development of alternative treatments that specifically target aberrant pathways of fibrosis which are relevant to disease progression in FSGS. There is a need for a flexible Phase II study design which will test such novel antifibrotic strategies in order to identify agents suitable for phase III testing. Methods/Design The Novel Therapies for Resistant Focal Segmental Glomerulosclerosis (FONT) project is a multicenter Phase I/II RCT designed to investigate the potential efficacy of novel therapies for resistant FSGS. Adalimumab and galactose will be evaluated against conservative therapy consisting of the combination of lisinopril, losartan and atorvastatin. The sample size is defined to assure that if one of the treatments has a superior response rate compared to that of the other treatments, it will be selected with high probability for further evaluation. Comparison of primary and secondary endpoints in each study arm will enable a choice to be made of which treatments are worthy of further study in future Phase III RCT. Discussion This report highlights the key features of the FONT II RCT including the two-step outcome analysis that will expedite achievement of the study objectives. The proposed phase II study design will help to identify promising agents for further testing while excluding ineffective agents. This staged approach can help to prevent large expenditures on unworthy therapeutic agents in the management of serious but rare kidney diseases Trial Registration ClinicalTrials.gov, NCT00814255

Abstract
OBJECTIVE The purpose of this study was to investigate the association between cultural views, English proficiency, and regular cervical cancer screening among older Chinese women. METHODS The study sample consisted of 473 asymptomatic Chinese participants aged 50 and older recruited from community organizations. The study outcome was regular receipt of Pap tests, defined as having a recent test in the past 3 years and another within 3 years before the present test. Eastern cultural views were measured by a 30-item scale that assessed beliefs about illness and cancer. Sociodemographics, cancer worry, physician recommendation, health insurance, and access barriers were included as covariates in multiple logistic regression models. RESULTS A total of 239 (50.5%) Chinese American women had regular Pap tests. Findings indicate that 1) women who held more traditional Chinese cultural views were less likely to be a regular screener (odds ratio [OR], 0.96; 95% confidence interval [CI], 0.94-0.99); 2) women with higher English proficiency were 1.39 times more likely to have received regular Pap tests than women with lower proficiency (OR, 1.39; 95% CI, 1.13-1.72). CONCLUSION Cultural views and English proficiency were significant predictors of older Chinese American women regular receipt of Pap tests. Future research is needed to identify and design culturally and linguistically competent programs to promote cervical cancer screening.
