    Patients with long-standing inflammatory bowel disease (IBD) have an increased risk of developing colorectal cancer (CRC). Many of the molecular alterations responsible for sporadic colorectal cancer, namely chromosomal instability, microsatellite instability, and hypermethylation, also play a role in colitis-associated colon carcinogenesis. Colon cancer risk in inflammatory bowel disease increases with longer duration of colitis, greater anatomic extent of colitis, the presence of primary sclerosing cholangitis, family history of CRC and degree of inflammation of the bowel. Chemoprevention includes aminosalicylates, ursodeoxycholic acid, and possibly folic acid and statins. To reduce CRC mortality in IBD, colonoscopic surveillance with random biopsies remains the major way to detect early mucosal dysplasia. When dysplasia is confirmed, proctocolectomy is considered for these patients. Patients with small intestinal Crohn's disease are at increased risk of small bowel adenocarcinoma. Ulcerative colitis patients with total proctocolectomy and ileal pouch anal- anastomosis have a rather low risk of dysplasia in the ileal pouch, but the anal transition zone should be monitored periodically. Other extra intestinal cancers, such as hepatobiliary and hematopoietic cancer, have shown variable incidence rates. New endoscopic and molecular screening approaches may further refine our current surveillance guidelines and our understanding of the natural history of dysplasia.

The interventions were designed to improve awareness and understanding of the NHS Bowel Cancer Screening Programme (BCSP and assist stool sampling. Logistic regression analysis of BCSP London data (N=205,541 invitees aged 60–74 compared uptake at 12 weeks between intervention groups and a control group, sent kits as usual between January-April 2013 and January-April 2014. An endorsement flyer, included with gFOBT kits, had no impact on uptake (P=0.68. In 60–69-year-olds, there was a small but significant increase in modelled uptake amongst invitees sent both the flyer and a kit enhancement pack compared with controls (45.1% versus 43.4%, OR=1.07, P=0.047. In North East London, the flyer together with outdoor advertising was associated with a small but significant increase (45.6% versus 43.4%, OR=1.09, P=0.027. The largest increases were seen when all three interventions (flyer, pack, and advertising were combined (49.5% versus 43.4%, OR=1.28, P<0.001. The increased uptake in the intervention groups was largest in “first-timers” and smaller amongst previous nonresponders and previously screened invitees.

    Cancer screening is a means to detect cancer early with the goal of decreasing morbidity and mortality. At present, there is a reasonable consensus regarding screening for breast, cervical and colorectal cances and the role of screening is under trial in case of cancers of the lung,  ovaries and prostate. On the other hand, good screening tests are not available for some of the commonest cancers in India like the oral, pharyngeal, esophageal and stomach cancers.

    Mouth cancer is a major health problem. Multiple risk factors for developing mouth cancer have been studied and include history of tobacco and alcohol abuse, age over 40, exposure to ultraviolet radiation, human papilloma virus infection (HPV), nutritional deficiencies, chronic irritation, and existence or oral potentially malignant lesions such as leukoplakia and lichen planus. An important risk factor for mouth cancer is chronic immunosuppression and has been extensively reported after solid organ transplantation as well as HIV-infected patients. Diagnosis of inflammatory bowel disease (IBD) is not yet considered as a risk factor for oral cancer development. However, a significant number of patients with IBD are receiving immunosuppressants and biological therapies which could represent potential oral oncogenic factors either by direct oncogenic effect or by continuous immunosuppression favoring carcinogenesis, especially in patients with HPV(+) IBD. Education on modifiable risk behaviors in patients with IBD is the cornerstone of prevention of mouth cancer. Oral screening should be performed for all patients with IBD, especially those who are about to start an immunosuppressant or a biologic. PMID:26671147

  17. Continuous quality improvement of colorectal cancer screening

    2013-01-01

    Quality assurance is a key issue in colorectal cancer screening, because effective screening is able to improve primary prevention of the cancer. The quality measure may be described in terms:how well the screening test tells who truly has a disease (sensitivity) and who truly does not have a disease (specificity). This paper raises concerns about identification of the optimal screening test for colorectal cancer. Colonoscopy vs flexible sigmoidoscopy in colorectal cancer screening has been a source of ongoing debate. A multicentre randomised controlled trial comparing flexible sigmoidoscopy with usual care showed that flexible sigmoidoscopy screening is able to diminish the incidence of distal and proximal colorectal cancer, and also mortality related to the distal colorectal cancer. However, colonoscopy provides a more complete examination and remains the more sensitive exam than flexible sigmoidoscopy. Moreover, colonoscopy with polypectomy significantly reduces colorectal cancer incidence and colorectal cancer-related mortality in the general population. The article considers the relative merits of both methods and stresses an ethical aspect of patient’s involvement in decision-making. Patients should be informed not only about tests tolerability and risk of endoscopy complications, but also that different screening tests for bowel cancer have different strength to exclude colonic cancer and polyps. The authorities calculate effectiveness and costs of the screening tests, but patients may not be interested in statistics regarding flexible sigmoidoscopy screening and from an ethical point of view, they have the right to chose colonoscopy, which is able to exclude a cancer and precancerous lesions in the whole large bowel.

    Both ulcerative colitis and Crohn's disease carry an increased risk of developing colorectal cancer. Established risk factors for cancer among patients with inflammatory bowel disease (IBD) include the younger age at diagnosis, greater extent and duration of disease, increased severity of inflammation, family history of colorectal cancer and coexisting primary sclerosing cholangitis. Recent evidence suggests that current medical therapies and surgical techniques for inflammatory bowel disease may be reducing the incidence of this complication. Nonetheless heightened vigilance and a careful, comprehensive approach to prevent or minimize the complications of invasive cancer are warranted in this unique cohort of patients. Current guidelines for the prevention and early detection of cancer in this high risk population are grounded in the concept of an inflammation-dysplasia-carcinoma sequence. A thorough understanding of the definition and natural history of dysplasia in IBD, as well as the challenges associated with detection and interpretation of dysplasia are fundamental to developing an effective strategy for surveillance and prevention, and understanding the limitations of the current approach to prevention. This article reviews the current consensus guidelines for screening and surveillance of cancer in IBD, as well as presenting the evidence and rationale for chemoprevention of cancer and a discussion of emerging technologies for the detection of dysplasia.

    March is national colorectal cancer awareness month. It is estimated that as many as 60% of colorectal cancer deaths could be prevented if all men and women aged 50 years or older were screened routinely. In 2000, Katie Couric's televised colonoscopy led to a 20% increase in screening colonoscopies across America, a stunning rise called the "Katie Couric Effect". This event demonstrated how celebrity endorsement affects health behavior. Currently, discussion is ongoing about the optimal strategy for CRC screening, particularly the costs of screening colonoscopy. The current CRC screening guidelines are summarized in Table 2. Debates over the optimum CRC screening test continue in the face of evidence that 22 million Americans aged 50 to 75 years are not screened for CRC by any modality and 25,000 of those lives may have been saved if they had been screened for CRC. It is clear that improving screening rates and reducing disparities in underscreened communities and population subgroups could further reduce colorectal cancer morbidity and mortality. National Institutes of Health consensus identified the following priority areas to enhance the use and quality of colorectal cancer screening: Eliminate financial barriers to colorectal cancer screening and appropriate follow-up of positive results of colorectal cancer screening. Develop systems to ensure the high quality of colorectal cancer screening programs. Conduct studies to determine the comparative effectiveness of the various colorectal cancer screening methods in usual practice settings. Encouraging population adherence to screening tests and allowing patients to select the tests they prefer may do more good (as long as they choose something) than whatever procedure is chosen by the medical profession as the preferred test.

    Since the release of the US Preventive Services Task Force and Centers for Medicare and Medicaid Services recommendations for lung cancer screening, low-dose chest computed tomography screening has moved from the research arena to clinical practice. Lung cancer screening programs must reach beyond image acquisition and interpretation and engage in a multidisciplinary effort of clinical shared decision-making, standardization of imaging and nodule management, smoking cessation, and patient follow-up. Standardization of radiologic reports and nodule management will systematize patient care, provide quality assurance, further reduce harm, and contain health care costs. Although the National Lung Screening Trial results and eligibility criteria of a heavy smoking history are the foundation for the standard guidelines for low-dose chest computed tomography screening in the United States, currently only 27% of patients diagnosed with lung cancer would meet US lung cancer screening recommendations. Current and future efforts must be directed to better delineate those patients who would most benefit from screening and to ensure that the benefits of screening reach all socioeconomic strata and racial and ethnic minorities. Further optimization of lung cancer screening program design and patient eligibility will assure that lung cancer screening benefits will outweigh the potential risks to our patients. PMID:27306387

    Lung cancer is the leading cause of cancer mortality in the United States and worldwide. Since lung cancer outcomes are dependent on stage at diagnosis with early disease resulting in longer survival, the goal of screening is to capture lung cancer in its early stages when it can be treated and cured. Multiple studies have evaluated the use of chest X-ray (CXR) with or without sputum cytologic examination for lung cancer screening, but none has demonstrated a mortality benefit. In contrast, the multicenter National Lung Screening Trial (NLST) from the United States found a 20 % reduction in lung cancer mortality following three consecutive screenings with low-dose computed tomography (LDCT) in high-risk current and former smokers. Data from European trials are not yet available. In addition to a mortality benefit, lung cancer screening with LDCT also offers a unique opportunity to promote smoking cessation and abstinence and may lead to the diagnoses of treatable chronic diseases, thus decreasing the overall disease burden. The risks of lung cancer screening include overdiagnosis, radiation exposure, and false-positive results leading to unnecessary testing and possible patient anxiety and distress. However, the reduction in lung cancer mortality is a benefit that outweighs the risks and major health organizations currently recommend lung cancer screening using age, smoking history, and quit time criteria derived from the NLST. Although more research is needed to clearly define and understand the application and utility of lung cancer screening in the general population, current data support that lung cancer screening is effective and should be offered to eligible beneficiaries.

    Lung cancer is the leading cause of cancer deaths worldwide as well as in Korea. A recent National Lung Screening Trial in U.S. revealed that low-dose CT (LDCT) screening reduced lung cancer specific mortality by 20% in high risk individuals as compared to chest radiograph screening. Based on this evidence, several expert societies in U.S. and Korean multisociety collaborative committee developed guidelines for recommendation of lung cancer screening using annual LDCT in high risk populations. In most of the societies high risk groups are defined as persons aged 55 to 74 years, who are current smokers with history of smoking of more than 30 packs per year or ex-smokers, who quit smoking up to 15 or more years ago. The benefits of LDCT screening are modestly higher than the harms in high risk individuals. The harms included a high rate of false-positive findings, over-diagnosis and radiation-related deaths. Invasive diagnostic procedure due to false positive findings may lead to complications. LDCT should be performed in qualified hospitals and interpreted by expert radiologists. Recently, the American College of Radiology released the current version of Lung cancer CT screening Reporting and Data Systems. Education and actions to stop smoking must be offered to current smokers.

    Inflammatory bowel diseases (IBD) are associated with an increased risk of gastrointestinal cancers depending on the specific type of IBD, the extent of the disease and its location. Patients with IBD and extensive colonic involvement are at increased risk of colorectal cancer whereas patients with Crohn disease have an increased risk for small-bowel and anal carcinoma. These cancers preferentially develop on sites of longstanding inflammation. In regards to colon cancer, several key pathogenic events are involved, including chromosomal instability, microsatellite instability and hypermethylation. The risk for colon cancer in IBD patients correlates with longer disease duration, presence of sclerosing cholangitis, pancolitis, family history of colorectal cancer, early onset of the disease and severity of bowel inflammation. Identification of increased colorectal cancer risk in individual IBD patients has led to formal surveillance guidelines. Conversely, although an increased risk for other types of cancer has been well identified, no specific formal screening recommendations exist. Consequently, the role of the radiologist is crucial to alert the referring gastroenterologist when a patient with IBD presents with unusual imaging findings at either computed tomography (CT) or magnetic resonance (MR) imaging. This review provides an update on demographics, molecular, clinical and histopathological features of gastrointestinal cancers in IBD patients including colorectal carcinoma, small bowel adenocarcinoma, neuroendocrine tumors and anal carcinoma, along with a special emphasis on the current role of CT and MR imaging.

    In order to update the previous version of the European Code against Cancer and formulate evidence-based recommendations, a systematic search of the literature was performed according to the methodology agreed by the Code Working Groups. Based on the review, the 4th edition of the European Code against Cancer recommends: "Take part in organized cancer screening programmes for: Bowel cancer (men and women); Breast cancer (women); Cervical cancer (women)." Organized screening programs are preferable because they provide better conditions to ensure that the Guidelines for Quality Assurance in Screening are followed in order to achieve the greatest benefit with the least harm. Screening is recommended only for those cancers where a demonstrated life-saving effect substantially outweighs the potential harm of examining very large numbers of people who may otherwise never have, or suffer from, these cancers, and when an adequate quality of the screening is achieved. EU citizens are recommended to participate in cancer screening each time an invitation from the national or regional screening program is received and after having read the information materials provided and carefully considered the potential benefits and harms of screening. Screening programs in the European Union vary with respect to the age groups invited and to the interval between invitations, depending on each country's cancer burden, local resources, and the type of screening test used For colorectal cancer, most programs in the EU invite men and women starting at the age of 50-60 years, and from then on every 2 years if the screening test is the guaiac-based fecal occult blood test or fecal immunochemical test, or every 10 years or more if the screening test is flexible sigmoidoscopy or total colonoscopy. Most programs continue sending invitations to screening up to the age of 70-75 years. For breast cancer, most programs in the EU invite women starting at the age of 50 years, and not before the age

Most programs continue sending invitations to screening up to the age of 70-75 years. For breast cancer, most programs in the EU invite women starting at the age of 50 years, and not before the age

    Neither extended surgery nor extended indication for surgery has improved survival in patients with pancreatic cancer. According to autopsy studies, presumably 90% are metastatic. The only cure is complete removal of the tumor at an early stage before it becomes a systemic disease or becomes invasive. Early detection and screening of individuals at risk is currently under way. This article reviews the evidence and methods for screening, either familial or sporadic. Indication for early-stage surgery and precursors are discussed. Surgeons should be familiar with screening because it may provide patients with a chance for cure by surgical resection.

    2015-10-01

    Colorectal cancer (CRC) is the second most common cause of cancer death in the US. Earlier detection can allow treatment with curative intent and improve prognosis. Optical and virtual colonoscopy are widely used in screening for colonic polyps and in the investigation of suspected CRC. However, contrast-enhanced computed tomography (CT) is still performed to investigate various non-specific abdominal complaints. Hence, a significant number of CRC are identified on contrast-enhanced CT without bowel preparation. We describe several signs, which when present in tandem, raise suspicion of CRC, and may warrant further investigation with optical colonoscopy. These include an intraluminal mass, eccentric or circumferential wall thickening >3 mm, focal wall enhancement, pericolic fat stranding, a cluster of >3 local lymph nodes, and enlarged lymph nodes >10 mm in short axis. Multiplanar evaluation of the bowel should be performed on all CT abdominal studies, including those without bowel preparation, to identify subtle features of CRC. PMID:26194811

    2015-09-01

    Colonoscopy represents a very important diagnostic modality for screening for colorectal cancer, because it has the ability to both detect and effectively remove pro-malignant and malignant lesions. It is recommended by almost all international and national gastroenterology and cancer societies, as an initial screening modality or, following a positive fecal occult blood test, to be performed every 10 years in individuals of average risk starting from the age of 50. However, a significant problem is the so-called post-screening (interval) polyps and cancers found some years after the index colonoscopy. In order to reduce the rate of interval cancers it is extremely necessary to optimize the quality and effectiveness of colonoscopy. Bowel preparation is of paramount importance for both accurate diagnosis and subsequent treatment of lesions found on colonoscopy. The quality of bowel preparation could be significantly improved by splitting the dose regimens, a strategy that has been shown to be superior to single-dose regimen. A good endoscopic technique and optimal withdrawal time offering adequate time for inspection, would further optimize the rate of cecal intubation and the number of lesions detected. During the last years, sophisticated devices have been introduced that would further facilitate cecal intubation. The percentage of total colonoscopies is now super-passing the level of 95 % allowing the adenoma detection rate to be greater than the suggestive level of 25 % in men and 15 % in women. This review aims to provide the reader with the current knowledge concerning indications, usefulness, limitations and future perspectives of this probably most important screening technique for colorectal cancer available today.

  3. Pharmacological treatment of bowel obstruction in cancer patients.

    LENUS (Irish Health Repository)

    O'Connor, Brenda

    2012-02-01

    INTRODUCTION: Malignant bowel obstruction (MBO) is a common complication of advanced cancer, occurring most frequently in gynaecological and colorectal cancer. Its management remains complex and variable. This is in part due to the lack of evidence-based guidelines for the clinicians involved. Although surgery should be considered the primary treatment, this may not be feasible in patients with a poor performance status or advanced disease. Advances have been made in the medical management of MBO which can lead to a considerable improvement in symptom management and overall quality of life. AREAS COVERED: This review emphasizes the importance of a prompt diagnosis of MBO with early introduction of pharmacological agents to optimize symptom control. The authors summarize the treatment options available for bowel obstruction in those patients for whom surgical intervention is not a feasible option. The authors also explore the complexities involved in the introduction of parenteral hydration and total parenteral nutrition in this group of patients. EXPERT OPINION: It is not always easy to distinguish reversible from irreversible bowel obstruction. Early and aggressive management with the introduction of pharmacological agents including corticosteroids, octreotide and anti-cholinergic agents have the potential to maintain bowel patency, and allow for more rapid recovery of bowel transit. A combination of analgesics, anti-emetics and anti-cholinergics with or without anti-secretory agents can successfully improve symptom control in patients with irreversible bowel obstruction.

    The management of inflammatory bowel disease (IBD) has changed since the mid-1990s (e.g., use of thiopurines/anti-TNFα agents, improved surveillance programs), possibly affecting cancer risk. To establish current cancer risk in IBD, updates are warranted from cohorts covering this time span, and detailed enough to study associations with phenotype and medication. We studied intestinal-, extra-intestinal- and overall cancer risk in the Dutch population-based IBDSL cohort. In total, 1,157 Crohn's disease (CD) and 1,644 ulcerative colitis (UC) patients were diagnosed between 1991 and 2011, and followed until 2013. Standardized incidence ratios (SIRs) were calculated for CD and UC separately, as well as for gender-, phenotype-, disease duration-, diagnosis era- and medication groups. We found an increased risk for colorectal cancer in CD patients with colon involvement (SIR 2.97; 95% CI 1.08-6.46), but not in the total CD or UC population. In addition, CD patients were at increased risk for hematologic- (2.41; 1.04-4.76), overall skin- (1.55; 1.06-2.19), skin squamous cell- (SCC; 3.83; 1.83-7.04) and overall cancer (1.28; 1.01-1.60), whereas UC patients had no increased risk for extra-intestinal- and overall cancer. Finally, in a medication analysis on CD and UC together, long-term immunosuppression exposure (>12 months) was associated with an increased risk for hematologic cancer, non-Hodgkin lymphoma, SCC and overall cancer, and this increase was mainly attributed to thiopurines. IBD patients with long-term immunosuppression exposure can be considered as having a higher cancer risk, and our data support the advice in recent IBD guidelines to consider skin cancer screening in these patients.

    Colorectal cancer is the second most common cancer among Latinos, but a lower percentage of Latinos are screened than Whites and Blacks. Along with recognized economic barriers, differences in knowledge and perceptions might impede colorectal screening among Latinos. We conducted 147 individual, qualitative interviews with Dominicans and Puerto Ricans in the northeastern United States to explore their explanatory models for colorectal cancer and screening barriers. Many participants had not previously heard of colorectal cancer. The most commonly mentioned cause of colorectal cancer was anal sex. Also considered risks were "bad food," digestion leading to constipation, and strained bowel movements. Screening barriers included stigma, misperceptions, embarrassment, and machismo. Progress toward increasing colorectal cancer screening requires normalization of this screening among Latinos. Higher patient familiarity, along with improved physician counseling and referral, might contribute to reducing stigma and other barriers, and to enhancing knowledge and Latino community support of colorectal cancer screening.

    Patients with inflammatory bowel disease have an additional risk of developing cancer compared with the general population. This is due to local chronic inflammation that leads to the development of gastrointestinal cancers and the use of thiopurines, associated with a higher risk of lymphoproliferative disorders, skin cancers, or uterine cervical cancers. Similar to the general population, a previous history of cancer in inflammatory bowel disease patients increases the risk of developing a secondary cancer. Large studies have not shown an increased risk of cancer in patients treated with biologics. In this review we discuss the prevention and treatment of cancer in patients with inflammatory bowel disease. PMID:27065724

    AIM:To study the sensitivity,specificity and cost effectiveness of barium meal follow through with pneumocolon (BMFTP) used as a screening modality for patients with chronic abdominal pain of luminal origin in developing countries.METHODS:Fifty patients attending the Gastroenterology Unit,SMS Hospital,whose clinical evaluation revealed chronic abdominal pain of bowel origin were included in the study.After routine testing,BMFT,BMFTP,contrast enhanced computed tomography (CECT) of the abdomen,barium enema and colonoscopy were performed.The sensitivity,specificity and cost effectiveness of these imaging modalities in the detection of small and/or large bowel lesions were compared.RESULTS:Out of fifty patients,structural pathology was found in ten.Nine out of these ten patients had small bowel involvement while seven had colonic involvement alone or in combination with small bowel involvement.The sensitivity of BMFTP was 100% compared to 88.89% with BMFT when detecting small bowel involvement (BMFTP detected one additional patient with ileocecal involvement).The sensitivity and specificity of BMFTP for the detection of colonic pathology were 85.71% and 95.35%(41/43),respectively.Screening a patient with chronic abdominal pain (bowel origin) using a combination of BMFT and barium enema cost significantly more than BMFTP while their sensitivity was almost comparable.CONCLUSION:BMFTP should be included in the investigative workup of patients with chronic abdominal pain of luminal origin,where either multiple sites (small and large intestine) of involvement are suspected or the site is unclear on clinical grounds.BMFTP is an economical,quick and comfortable procedure which obviates the need for colonoscopy in the majority of patients.

    Regulatory T cells (Tregs) are key elements in immunological self-tolerance.The number of Tregs may alter in both peripheral blood and in colonic mucosa during pathological circumstances.The local cellular,microbiological and cytokine milieu affect immunophenotype and function of Tregs.Forkhead box P3+ Tregs function shows altered properties in inflammatory bowel diseases (IBDs).This alteration of Tregs function can furthermore be observed between Crohn's disease and ulcerative colitis,which may have both clinical and therapeutical consequences.Chronic mucosal inflammation may also influence Tregs function,which together with the intestinal bacterial flora seem to have a supporting role in colitis-associated colorectal carcinogenesis.Tregs have a crucial role in the immunoevasion of cancer cells in sporadic colorectal cancer.Furthermore,their number and phenotype correlate dosely with the clinical outcome of the disease,even if their contribution to carcinogenesis has previously been controversial.Despite knowledge of the clinical relationship between IBD and colitis-associated colon cancer,and the growing number of immunological aspects encompassing sporadic colorectal carcinogenesis,the molecular and cellular links amongst Tregs,regulation of the inflammation,and cancer development are still not well understood.In this paper,we aimed to review the current data surrounding the role of Tregs in the pathogenesis of IBD,colitis-associated colon cancer and sporadic colorectal cancer.

    We are using whole-body positron emission tomography (PET) for cancer screening. A total of 1,105 healthy subjects have undergone PET studies 1,138 times in fifteen months. Emission scans were performed from the pelvis to the maxilla 45 to 60 minutes after intravenous administration of 260 to 370 MBq 2-deoxy-2-[18F]fluoro-D-glucose (FDG). Malignant tumors were detected with PET in nine patients (0.81%): 2 lung cancers, 2 colonic cancers, 1 breast cancer, 1 thyroid cancer, 1 gastric cancer, 1 renal cancer, and 1 lymphoma. Eight of these patients underwent surgery (excepting the lymphoma patient). Lymph node metastasis was not observed in any of the eight cases and surgery was curative. PET scan results were negative in the cases of three prostatic cancers, one bladder cancer, and two colonic mucosal cancers. High FDG accumulations were noticed in benign lesions such as sarcoidosis, chronic thyroiditis, pulmonary tuberculoma, Warthin's tumor of the parotid gland, and chronic sinusitis. In some cases, image artifacts caused by intense myocardial FDG accumulations resulted in incomplete examinations of the lung. Occasionally, high FDG accumulations were observed in the bowel. Our study results suggest the possibility of using whole-body PET for detecting wide varieties of cancers in resectable stages.

    Celebrities often promote cancer screening by relating personal anecdotes about their own diagnosis or that of a loved one. We used data obtained from a random-digit dialing survey conducted in the United States from December 2001 through July 2002 to examine the extent to which adults of screening age without a history of cancer had seen or heard or been influenced by celebrity endorsements of screening mammography, prostate-specific antigen (PSA) testing, or sigmoidoscopy or colonoscopy. The survey response rate was 72% among those known to be eligible and 51% among potentially eligible people accounting for those who could not be contacted. A total of 360 women aged 40 years or older and 140 men aged 50 years or older participated in the survey. Most respondents reported they "had seen or heard a celebrity talk about" mammography (73% of women aged 40 years or older), PSA testing (63% of men aged 50 years or older), or sigmoidoscopy or colonoscopy (52% of adults aged 50 years or older). At least one-fourth of respondents who had seen or heard a celebrity endorsement said that the endorsement made them more likely to undergo mammography (25%), PSA testing (31%), or sigmoidoscopy or colonoscopy (37%).

    The results of the National Lung Screening Trial (NLST) have provided the medical community and American public with considerable optimism about the potential to reduce lung cancer mortality with imaging-based screening. Designed as a randomized trial, the NLST has provided the first evidence of screening benefit by showing a 20% reduction in lung cancer mortality and a 6.7% reduction in all-cause mortality with low dose helical computed tomography (LDCT) screening relative to chest X-ray. The major harms of LDCT screening include the potential for radiation-induced carcinogenesis; high false-positivity rates in individuals without lung cancer, and overdiagnosis. Following the results of the NLST, the National Comprehensive Cancer Network (NCCN) published the first of multiple lung cancer screening guidelines under development by major medical organizations. These recommendations amalgamated screening cohorts, practices, interpretations, and diagnostic follow-up based on the NLST and other published studies to provide guidance for the implementation of LDCT screening. There are major areas of opportunity to optimize implementation. These include standardizing practices in the screening setting, optimizing risk profiles for screening and for managing diagnostic evaluation in individuals with indeterminate nodules, developing interdisciplinary screening programs in conjunction with smoking cessation, and approaching all stakeholders systematically to ensure the broadest education and dissemination of screening benefits relative to risks. The incorporation of validated biomarkers of risk and preclinical lung cancer can substantially enhance the effectiveness screening programs. PMID:24451779

    This case describes a 71 year old, post-menopausal woman who developed vaginal discharge. This complaint ultimately led to the discovery of bowel cancer in conjunction with a large sterile pyometra. The pyometra was not due to genital malignancy. The most likely conclusion is that the pyometra may have arisen as an inflammatory response to the adjacent bowel pathology.

    Colorectal carcinoma is a common cause of death throughout the world and may be prevented by routine control, which can detect precancerous neoplasms and early cancers before they undergo malignant transformation or metastasis. Three strategies may improve colon cancer screening rates: convince the population about the importance of undergoing a screening test; achieve higher efficacy in standard screening tests and make them more available to the community and develop new more sensitive and efficacious screening methods and make them available as routine tests. In this light, the present study seeks to review these three means through which to increase colon cancer screening rates.

    Colonoscopic surveillance is advocated in patients with inflammatory bowel disease(IBD) for detection of dys-plasia. There are many issues regarding surveillance in IBD: the risk of colorectal cancer seems to be de-creasing in the majority of recently published studies, necessitating revisions of surveillance strategy; surveil-lance guidelines are not based on concrete evidence; commencement and frequency of surveillance, cost-effectiveness and adherence to surveillance have been issues that are only partly answered. The traditional technique of random biopsy is neither evidence-based nor easy to practice. Therefore, highlighting abnormal areas with newer technology and biopsy from these areas are the way forward. Of the newer technology, digital mucosal enhancement, such as high-definition white light endoscopy and chromoendoscopy(with magnification) have been incorporated in guidelines. Dyeless chromoendoscopy(narrow band imaging) has not yet shown potential, whereas some forms of digital chromoendoscopy(i-Scan more than Fujinon intelligent color enhancement) have shown promise for colonoscopic surveillance in IBD. Other techniquessuch as autofluorescence imaging, endomicroscopy and endocytoscopy need further evidence. Surveillance with genetic markers(tissue, serum or stool) is at an early stage. This article discusses changing epidemiology of colorectal cancer development in IBD and critically evaluates issues regarding colonoscopic surveillance in IBD.

    Patients with inflammatory bowel disease (IBD) are at increased risk for colorectal cancer (CRC). Risk factors for the development of CRC in the setting of IBD include disease duration, anatomic extent of disease,age at time of diagnosis, severity of inflammation,family history of colon cancer, and concomitant primary sclerosing cholangitis. The current surveillance strategy of surveillance colonoscopy with multiple random biopsies most likely reduces morbidity and mortality associated with IBD-related CRC. Unfortunately,surveillance colonoscopy also has severe limitations including high cost, sampling error at time of biopsy,and interobserver disagreement in histologically grading dysplasia. Furthermore, once dysplasia is detected there is disagreement about its management.Advances in endoscopic imaging techniques are already underway, and may potentially aid in dysplasia detection and improve overall surveillance outcomes.Management of dysplasia depends predominantly on the degree and focality of dysplasia, with the mainstay of management involving either proctocolectomy or continued colonoscopic surveillance. Lastly, continued research into additional chemopreventive agents may increase our arsenal in attempting to reduce the incidence of IBD-associated CRC.

  18. What we have learned from randomized trials of prostate cancer screening

    2011-01-01

    The introduction of prostate-specific antigen (PSA) for prostate cancer screening in the late 1980s led to an epidemic of prostate cancer, particularly in developed countries. However, the first valid reports from randomized controlled trials on the efficacy of screening were not published until 2009. Men in the screening group in the European Randomized Study of Screening for Prostate Cancer were 20% less likely than those in the control group to die from prostate cancer. The absolute difference was only 0.7/1000, implying that over 1400 men needed to be screened to prevent one prostate cancer death. Screening was also associated with a 70% increased risk for being diagnosed with prostate cancer. The American Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial found no survival benefit for screening. Results were not conclusive because a substantial proportion of study subjects had previously undergone PSA testing, over half of the control group had PSA testing, follow-up was relatively short, and fewer than 100 subjects died from prostate cancer. Balancing the potential survival benefit from screening is the risk of overdiagnosis-finding cancers that would not otherwise cause clinical problems-and the risk of treatment complications, including urinary, sexual and bowel dysfunction. Prostate cancer screening efforts would benefit from improved biomarkers, which more readily identify clinically important cancers. Cancer control efforts might also need to include chemoprevention, though currently available agents are controversial. In the meantime, patients need to be supported in achieving informed decisions on whether to be screened for prostate cancer.

    European studies have contributed significantly to the understanding of lung cancer screening. Smoking within screening, quality of life, nodule management, minimally invasive treatments, cancer prevention programs, and risk models have been extensively investigated by European groups. Mortality data from European screening studies have not been encouraging so far, but long-term results of the NELSON study are eagerly awaited. Investigations on molecular markers of lung cancer are ongoing in Europe; preliminary results suggest they may become an important screening tool in the future.

    AIM:To investigate barriers to colorectal cancer (CRC) screening in a community population. METHODS:We conducted a community-based case-control study in an urban Chinese population by questionnaire. Cases were selected from those completing both a fecal occult blood test (FOBT) case and colonoscopy in a CRC screening program in 2004. Control groups were matched by gender, age group and community. Control 1 included those having a positive FOBT but refusing a colonoscopy. Control 2 included those who refused both an FOBT and colonoscopy. RESULTS:The impact of occupation on willingness to attend a colorectal screening program differed by gender. P for heterogeneity was 0.009 for case vs control group 1, 0.01 for case versus control group 2, and 0.80 for control group 1 vs 2. Poor awareness of CRC and its screening program, characteristics of screening tests, and lack of time affected the screening rate. Financial support, fear of pain and bowel preparation were barriers to a colonoscopy as a screening test. Eighty-two percent of control group 1 and 87.1% of control group 2 were willing attend if the colonoscopy was free, but only 56.3% and 53.1%,respectively, if it was self-paid. Multivariate odds ratios for case vs control group 1 were 0.10 among those unwilling to attend a free colonoscopy and 0.50 among those unwilling to attend a self-paid colonoscopy. CONCLUSION:Raising the public awareness of CRC and its screening, integrating CRC screening into the health care system, and using a painless colonoscopy would increase its screening rate.

    Purpose: Despite the widespread screening programs, cervical cancer remains the third most common cancer in developing countries. Based on the implementation of cervical screening programs with the referred adoption of improved screening methods in cervical cytology with the knowledge of the important role of the human papilloma virus (HPV) it's incidence is decreased in the developed world. Even if cervical HPV infection is incredibly common, cervical cancer is relatively rare. Depending on the rarity of invasive disease and the improvement of detection of pre-cancerous lesions due to the participation in screening programs, the goal of screening is to detect the cervical lesions early in order to be treated before cancer is developed. In populations with many preventive screening programs, a decrease in cervical cancer mortality of 50-75% is mentioned over the past 50 years. The preventive examination of vagina and cervix smear, Pap test, and the HPV DNA test are remarkable diagnostic tools according to the American Cancer Association guidelines, in the investigation of asymptomatic women and in the follow up of women after the treatment of pre-invasive cervical cancer. The treatment of cervical cancer is based on the FIGO 2009 cervical cancer staging.

  8. To screen or nor to screen: the prostate cancer dilemma

    Full Text Available The European Randomized Study of Screening for Prostate (ERSPC has updated their previous seminal report on prostate cancer mortality comparing screened men to controls. Now with 13 years follow-up, the rate ratio of prostate cancer mortality was 0.79 favoring the screened population. The authors concluded that there was a "substantial reduction in prostate cancer mortality attributable to testing with prostate-specific antigen (PSA" but they also stated that a "quantification of harms" needed to be addressed. The issue of harms was not addressed by the ERSPC (at least not in this report and hence this additional statement most likely reflects the controversy currently surrounding the risks associated with over-diagnosis and treatment of indolent diseases inadvertently detected by a screening protocol. [1] In addition, the positive results from this trial conflict with those of the prostate, lung, colorectal and ovarian (PLCO [2] study and require further elaboration.

  9. Screening for breast cancer post reduction mammoplasty

    International Nuclear Information System (INIS)

    Aim: To investigate whether remodelling of the breast after breast reduction surgery has an effect on mammographic cancer detection. Methods and materials: For women who attended population-based screening between January 1998 to December 2007, data were extracted on their age, history of previous breast reduction, and the result of screening (recall for further assessment, cancer, or no cancer). The number of cancers detected, recalls per 1000 screens and the characteristics of the cancers detected in the two groups was compared. Results: In total 244,147 women with 736,219 screening episodes were reviewed. In the 4743 women who had a breast reduction, 51 breast cancers were detected [age standardized rate (ASR) of 4.28 per 1000 screening episodes; 95% CI 3.11-5.46], compared with 4342 breast cancers in 239 404 women screened in the non-reduction group (ASR of 5.99 per 1000 screening episodes; 95% CI 5.81-6.16). There were fewer cancers in the breast reduction group with a relative risk of 0.71. There was no significant difference in the rate of recall between the two groups, with a crude recall rate of 46.1 per 1000 screening episodes post-breast reduction compared with 50.7 per 1000 screening episodes for women without breast reduction. There was no significant difference in the pathological type or location of the cancer between the two groups of women. Conclusion: Postoperative breast changes following reduction mammoplasty do not significantly hinder analysis of the screening mammogram.

  10. Lung Cancer Screening with Low Dose CT

    2014-01-01

    SUMMARY The announcement of the results of the NLST, showing a 20% reduction in lung-cancer specific mortality with LDCT screening in a high risk population, marked a turning point in lung cancer screening. This was the first time that a randomized controlled trial had shown a mortality reduction with an imaging modality aimed at early detection of lung cancer. Current guidelines endorse LDCT screening for smokers and former smokers ages 55 to 74, with at least a 30 pack year smoking history. Adherence to published algorithms for nodule follow-up is strongly encouraged. Future directions for screening research include risk stratification for selection of the screening population, and improvements in the diagnostic follow-up for indeterminate pulmonary nodules. As with screening for other malignancies, screening for lung cancer with LDCT has revealed that there are indolent lung cancers which may not be fatal. More research is necessary if we are to maximize the risk-benefit ratio in lung cancer screening. PMID:24267709

    Despite the efficacy of mammography and the widespread promotion of screening programmes, a significant number of eligible women still do not attend for regular breast screening. An integrative review methodology was considered the most appropriate means to critically analyse the available literature pertaining to factors which influence participation in breast cancer screening. From the extensive literature search, 12 selected core research papers met the inclusion criteria and were incorporated in the literature review. Four themes emerged from the literature which impact on participation in mammography screening: psychological and practical issues, ethnicity issues, influence of socioeconomic status and issues related to screening programmes. The recent Independent Review Panel on Breast Cancer Screening endorsed the importance of access to information which clearly communicates the harms and benefits of breast screening to enable women to make informed decisions about their health. The recommendations from the panel and others have been included in this review. PMID:24067312

    The controversial recent recommendation by the United States Preventive Services Task Force (USPSTF) against prostate-specific antigen (PSA) screening for early-stage prostate cancer has caused much debate. Whereas USPSTF recommendations against routine screening mammography in younger women resulted in fierce public outcry and eventual alteration in the language of the recommendation, the same public and political response has not been seen with PSA screening for prostate cancer. It is of paramount importance to ensure improved efficiency and transparency of the USPSTF recommendation process, and resolution of concerns with the current USPSTF recommendation against PSA screening for all ages.

  16. [Lung cancer screening - risk stratification : Who should undergo screening?].

    Science.gov (United States)

    Beer, L; Prosch, H

    2016-09-01

    Lung cancer is one of the leading causes of deaths in Europa and the USA. In approximately 75 % of lung cancer patients, bronchogenic carcinoma is detected at an advanced tumor stage; therefore, therapeutic options which aim at curing the disease in these patients are limited and treatment is mostly palliative. A relatively good prognosis is reserved for the minority of patients where the tumor is detected at an early stage and treatment is potentially curative. For this reason, early diagnosis of lung cancer could save lives. Retrospective analyses of the US national lung screening trial (NLST) showed that especially high-risk populations (e. g. higher age, positive smoking history, overweight and a positive family history for lung cancer) benefit most from lung cancer screening. Thus, the effectiveness of computed tomography (CT) screening can be improved by focusing on high-risk populations. This review article summarizes the risk stratification models of the large European and American screening studies and discusses possible future biomarkers for risk stratification. PMID:27495786

    Extramedullary plasmacytoma is a rare disease that is histopathologically defined as a solitary tumor composed of a monoclonal proliferation of cells with plasmacytic differentiation in an extramedullary site. Most of these tumors occur in the submucosa of the upper aerodigestive tract, and they rarely occur in the small bowel mesentery. We report here on a case of extramedullary plasmacytoma of the small bowel mesentery that was in association with a cecal cancer. Abdominal ultrasound and CT revealed a lobulated soft tissue mass with a cystic portion and peripheral calcification. In this case, the preoperative radiological diagnosis was difficult due to accompanying cecal cancer.

    Serum Raman spectroscopy (RS) has previously shown potential in oral cancer diagnosis and recurrence prediction. To evaluate the potential of serum RS in oral cancer screening, premalignant and cancer-specific detection was explored in the present study using 328 subjects belonging to healthy controls, premalignant, disease controls, and oral cancer groups. Spectra were acquired using a Raman microprobe. Spectral findings suggest changes in amino acids, lipids, protein, DNA, and β-carotene across the groups. A patient-wise approach was employed for data analysis using principal component linear discriminant analysis. In the first step, the classification among premalignant, disease control (nonoral cancer), oral cancer, and normal samples was evaluated in binary classification models. Thereafter, two screening-friendly classification approaches were explored to further evaluate the clinical utility of serum RS: a single four-group model and normal versus abnormal followed by determining the type of abnormality model. Results demonstrate the feasibility of premalignant and specific cancer detection. The normal versus abnormal model yields better sensitivity and specificity rates of 64 and 80% these rates are comparable to standard screening approaches. Prospectively, as the current screening procedure of visual inspection is useful mainly for high-risk populations, serum RS may serve as a useful adjunct for early and specific detection of oral precancers and cancer.

  5. Screening for colorectal cancer: what fits best?

    Colorectal cancer (CRC) screening has been shown to be effective in reducing CRC incidence and mortality. There are currently a number of screening modalities available for implementation into a population-based CRC screening program. Each screening method offers different strengths but also possesses its own limitations as a population-based screening strategy. We review the current evidence base for accepted CRC screening tools and evaluate their merits alongside their challenges in fulfilling their role in the detection of CRC. We also aim to provide an outlook on the demands of a low-risk population-based CRC screening program with a view to providing insight as to which modality would best suit current and future needs.

    Pancreatic cancer is a devastating disease with a median survival of approximately 6 months after diagnosis. Many factors are associated with a worse outcome; examples include late diagnosis, low resection rate, aggressive tumor behavior and a lack of an effective chemotherapy regimen. Owing to the low prevalence of pancreatic cancer relative to the diagnostic accuracy of present detection methods and the absence of promising treatment modalities, even in early stages, it is currently neither advisable nor cost effective to screen the general population. Efforts are focused on early screening of selected high-risk-cohorts, who account for approximately 10% of patients with pancreatic cancer. These include patients with chronic pancreatitis, individuals with a family history of pancreatic cancer, patients with hereditary pancreatitis, Peutz-Jeghers syndrome, cystic fibrosis or familial atypical multiple mole melanoma. At present, a multimodal-screening approach of endoscopic ultrasound, computed tomography and endoscopic retrograde cholangiopancreatography appears to be the most effective method to screen for pancreatic cancer in high-risk patients. Continued efforts are needed to elucidate effective testing to identify patients with nonhereditary risk factors who will benefit from screening protocols. A combined approach of serum markers, genetic markers and specific imaging studies may prove to be the future of pancreatic screening. PMID:19210116

    Lung cancer is the leading cause of cancer related death throughout the world. Lung cancer is an example of a disease for which a large percentage of the high-risk population can be easily identified via a smoking history. This has led to the investigation of lung cancer screening with low-dose helical/multi-detector CT. Evidences suggest that early detection of lung cancer allow more timely therapeutic intervention and thus a more favorable prognosis for the patient. The positive relationshi...

    Background: The European Community recommends mammography, cervical and colorectal cancer screening programmes. In Italy, cancer screening programmes have been included in the Basic Healthcare Parameters (Livelli Essenziali di Assistenza since 2001. Full national coverage of a population-based organized screening programme has been planned for in Italy and is being implemented. Since 2005, the Ministry of Health - Department of Prevention has formally charged The National Centre for Screening Monitoring (Osservatorio Nazionale Screening –ONS- with monitoring and promoting screening programmes nationwide. Participation of target populations is a key indicator of the impact and efficacy of a screening programme in reducing cancer mortality.

    Methods: Attendance of invitees is one of the indicators calculated every year in the quality control of Italian screening programmes. Data collection is organized by means of a structured questionnaire, sent by ONS to the referent for data collection in each Region, who then returns the completed questionnaires to the Regional Centre. Questionnaires are then sent to the National Centre. Logical and epidemiologic checks are performed at both levels. Every year ONS publishes reports on the results of the surveys. A feasibility study for a National data warehouse based on individual records is in progress. The national survey “Multiscopo sulle famiglie” and the Passi Study (Progetti delle Aziende Sanitarie per la Salute in Italia provided additional information regarding spontaneous preventive health care activities in the Italian population.

    Results: Mammography screening: In 2006, 78.2% of Italian women aged 50-69 lived in areas where organised screening was in place (theoretical extension, however, the distribution of the screening activity is not uniform (higher in Northern/Central Italy compared with Southern

  11. Screening for breast cancer with mammography

    International Nuclear Information System (INIS)

    Mammography is generally accepted as a useful problem-solving clinical tool in characterizing known breast lesions, so that appropriate and timely treatment can be given. However, it remains grossly underutilized at what it does best: screening. The major strengths of mammography are (a) its ability to detect breast cancer at a smaller, potentially more curable stage than any other examination, and (b) its proved efficacy in reducing breast cancer mortality in asymptomatic women aged 40-74. If, as has recently been estimated, screening with mammography and physical examination can be expected to lower breast cancer deaths by 40%-50% among those actually examined (13), then the lives of almost 20,000 U.S. women might be saved each year if screening were to become very widely used. The challenges of the next decade are clear, to mount much more effective campaigns to educate physicians and lay women about the life-saving benefits of breast cancer screening, to devise increasingly effective and lower cost screening strategies, to further improve the current high quality of mammographic imaging despite its increasing proliferation, and to train large numbers of breast imaging specialists to guarantee that the growing case load of screening and problem-solving mammograms is interpreted with a very high level of skill

  12. Breast cancer screening in Canada: a review

    International Nuclear Information System (INIS)

    Organized screening for breast cancer in Canada began in 1988 and has been implemented in all provinces and 2 of the 3 territories. Quality initiatives are promoted through national guidelines which detail best practices in various areas, including achieving quality through a client-service approach, recruitment and capacity, retention, quality of mammography, reporting, communication of results, follow-up and diagnostic workup, and program evaluation; it also offers detailed guidelines for the pathological examination and reporting of breast specimens. The Canadian Breast Cancer Data Base is a national breast cancer screening surveillance system whose objective is to collect information from provincial-screening programs. These data are used to monitor and evaluate the performance of programs and allow comparison with national and international results. A series of standardized performance indicators and targets for the evaluation of performance and quality of organized breast cancer screening programs have been developed from the data base. Although health care is a provincial responsibility in Canada, the collective reporting and comparison of results both nationally and internationally is beneficial in evaluating and refining both screening programs and individual radiologist performance. The results of Canadian performance indicators compare favourably with those of other well-established international screening programs. There are variations in performance indicators across the provinces and territories, but these differences are not extreme. (author)

    Full Text Available Very few studies examined the issue of regret on choosing colorectal cancer (CRC screening tests. We evaluated the determinants of regret and tested the hypothesis that regret over screening choices was associated with poorer screening compliance.A bowel cancer screening centre invited all Hong Kong citizens aged 50-70 years who were asymptomatic of CRC to participate in free-of-charge screening programmes. Upon attendance they attended health seminars on CRC and its screening, and were offered an option to choose yearly faecal immunochemical test (FIT for up to four years vs. one direct colonoscopy. They were not allowed to switch the screening option after decision. A self-administered, four-item validated survey was used to assess whether they regretted over their choice (> 2 = regretful from a scale of 0 [no regret]-5 [extreme regret]. A binary logistic regression model evaluated if initial regret over their choice was associated with poorer programme compliance.From 4,341 screening participants who have chosen FIT or colonoscopy, 120 (2.8% regretted over their decision and 1,029 (23.7% were non-compliant with the screening programme. Younger subjects and people who felt pressure when making their decision were associated with regret. People who regretted their decision were 2.189 (95% C.I. 1.361-3.521, p = 0.001 times more likely to be non-compliant with the programme.This study is the first to show that regret over the initial CRC screening choice was associated with later non-compliance. Screening participants who expressed regret over their choice should receive additional reminders to improve their programmatic compliance.

    1999-03-01

    We have studied hair using fibre X-ray diffraction studies with synchrotron radiation and find that hair from breast-cancer patients has a different intermolecular structure to hair from healthy subjects. These changes are seen in all samples of scalp and pubic hair taken from women diagnosed with breast cancer. All the hair samples from women who tested positive for a mutation of the BRCA1 gene, which is associated with a higher risk of breast cancer, also show these changes. Because our results are so consistent, we propose that such hair analyses may be used as a simple, non-invasive screening method for breast cancer.

    2016-01-01

    Results of a number of studies demonstrate that the serum prostate-specific antigen (PSA) in and of itself is an inadequate screening test. Today, one of the most pressing questions in prostate cancer medicine is how can screening be honed to identify those who have life-threatening disease and need aggressive treatment. A number of efforts are underway. One such effort is the assessment of men in the landmark Prostate Cancer Prevention Trial that has led to a prostate cancer risk calculator (PCPTRC), which is available online. PCPTRC version 2.0 predicts the probability of the diagnosis of no cancer, low-grade cancer, or high-grade cancer when variables such as PSA, age, race, family history, and physical findings are input. Modern biomarker development promises to provide tests with fewer false positives and improved ability to find high-grade cancers. Stockholm III (STHLM3) is a prospective, population-based, paired, screen-positive, prostate cancer diagnostic study assessing a combination of plasma protein biomarkers along with age, family history, previous biopsy, and prostate examination for prediction of prostate cancer. Multiparametric MRI incorporates anatomic and functional imaging to better characterize and predict future behavior of tumors within the prostate. After diagnosis of cancer, several genomic tests promise to better distinguish the cancers that need treatment versus those that need observation. Although the new technologies are promising, there is an urgent need for evaluation of these new tests in high-quality, large population-based studies. Until these technologies are proven, most professional organizations have evolved to a recommendation of informed or shared decision making in which there is a discussion between the doctor and patient.

  20. Bowel exposure in rectal cancer IMRT using prone, supine, or a belly board

    International Nuclear Information System (INIS)

    Purpose: To investigate bowel exposure using prone, supine, or two different belly boards for rectal cancer intensity modulated RT plans using a full bladder protocol. Methods and materials: For 11 volunteers four MR scans were acquired, on a flat table in prone, supine, and on two different belly boards (IT-V Medizintechnik GmbH® (BB1) and CIVCO® (BB2)), using a full bladder protocol. On each scan a 25 × 2 Gy IMRT plan was calculated. Results: BB2 led to an average bowel area volume reduction of 20–30% at any dose level compared to prone. BB1 showed a smaller dose reduction effect, while no differences between prone and supine were found. Differences between BB2 and prone, supine or BB1 were significant up to a level of respectively, 45, 35, and 30 Gy. The reducing effect varied among individuals, except for the 50 Gy region, where no effect was found. An increase in bladder volume of 100 cc led to a significant bowel area V15 reduction of 16% independent of scan type. Conclusions: In the low and intermediate dose region a belly board still attributes to a significant bowel dose reduction when using IMRT and a full bladder protocol. A larger bladder volume resulted in a significant decreased bowel area dose.

  1. Factors Influencing Colorectal Cancer Screening Participation

    2012-01-01

    Full Text Available Colorectal cancer (CRC is a major health problem worldwide. Although population-based CRC screening is strongly recommended in average-risk population, compliance rates are still far from the desirable rates. High levels of screening uptake are necessary for the success of any screening program. Therefore, the investigation of factors influencing participation is crucial prior to design and launches a population-based organized screening campaign. Several studies have identified screening behaviour factors related to potential participants, providers, or health care system. These influencing factors can also be classified in non-modifiable (i.e., demographic factors, education, health insurance, or income and modifiable factors (i.e., knowledge about CRC and screening, patient and provider attitudes or structural barriers for screening. Modifiable determinants are of great interest as they are plausible targets for interventions. Interventions at different levels (patient, providers or health care system have been tested across the studies with different results. This paper analyzes factors related to CRC screening behaviour and potential interventions designed to improve screening uptake.

    Mammographic screening is effective in reducing mortality from breast cancer. The issue is not whether mammography is effective, but whether the false positive rate and false negative rates can be reduced. This review will discuss controversies including the reduction in breast cancer mortality, overdiagnosis, the ideal screening candidate, and the optimal imaging modality for breast cancer screening. The article will compare and contrast screening mammography, tomosynthesis, whole-breast screening ultrasound, magnetic resonance imaging, and molecular breast imaging. Though supplemental imaging modalities are being utilized to improve breast cancer diagnosis, mammography still remains the gold standard for breast cancer screening.

    Full Text Available Abstract Approximately 10% of gastric cancer cases show familial clustering but only 1-3% of gastric carcinomas arise as a result of inherited gastric cancer predisposition syndromes. Direct proof that Hereditary Gastric Cancer a genetic disease with a germline gene defect has come from the demonstration of co-segregation of germline E-cadherin (CDH1 mutations with early onset diffuse gastric cancer in families with an autosomal dominant pattern of inheritance (HDGC. E-cadherin is a transmembrane calcium-dependent cell-adhesion molecule involved in cell-junction formation and the maintenance of epithelial integrity. In this review, we describe frequency and type of CDH1 mutations in sporadic and familial gastric cancer. Further we demonstrate the functional significance of some CDH1 germline missense mutations found in HDGC. We also discuss the CDH1 polymorphisms that have been associated to gastric cancer. We report other types of malignancies associated to HDGC, besides diffuse gastric cancer. Moreover, we review the data available on putative alternative candidate genes screened in familial gastric cancer. Finally, we briefly discuss the role of low-penetrance genes and Helicobacter pylori in gastric cancer. This knowledge is a fundamental step towards accurate genetic counselling, in which a highly specialised pre-symptomatic therapeutic intervention should be offered.

These effects have led to possible implications in the pathophysiology of immune-mediated diseases including multiple sclerosis and inflammatory bowel disease (IBD). In addition, vitamin D insufficiency has been linked to higher rates of cancers inclu...

    Colorectal cancer screening forms part of Scotland's cancer reduction strategy. Screened participants, who had undergone colonoscopy and had adenoma(s) removed, were invited to participate in the bowel health to better health (BHBH) programme. BHBH tested the hypothesis that a minimal contact lifestyle intervention could prove effective in promoting changes in diet and activity. Baseline and follow-up questionnaires on lifestyle and psycho-social measures were undertaken in adults randomised to BHBH or a comparison group (CG). The 3-month intervention comprised personalised lifestyle advice, goal-setting and social support to promote increases in physical activity, fibre, fruit and vegetables. Response rate to BHBH was 51 %. BHBH participants (n 32) increased their intake of fibre (DINE FFQ scores 30 (sd 11)-41 (sd 13)) significantly (P lifestyle recommendations (chi2 (1, n 62) = 8.196, P = 0.006). If sustained, the positive behaviour change achieved through this intervention has the potential to impact on the progression of chronic disease risk including CVD.

    Celiac disease (CD) is common in Caucasians, but thought to be rare in Asians. Our aim was to determine the prevalence of CD in Chinese patients with chronic diarrhea predominant irritable bowel syndrome (IBS-D).From July 2010 to August 2012, 395 adult patients with IBS-D and 363 age and sex-matched healthy controls were recruited in Zhongnan Hospital of Wuhan University and Xiaogan Central Hospital in Hubei province, central China. Patients with IBS-D were diagnosed according to the Rome III criteria. Serum Immunoglobulin (IgA/IgG) anti-human tissue transglutaminase (anti-htTG)-deamidated gliadin peptide (DGP) antibodies were measured in a single ELISA (QUANTA Lite h-tTG/DGP Screen). Upper endoscopy with duodenal biopsies and HLA-DQA1 and HLA-DQB1 genotyping were performed in seropositive subjects and a gluten-free diet was prescribed.Seven IBS-D patients (7/395, 1.77%) and 2 healthy controls (2/363, 0.55%), were positive for anti-htTG/DGP antibodies. Of these 9 cases, 1 was lost to follow-up, 3 were suspected to have CD and 5 were eventually diagnosed as CD with intestinal histological lesions classified as Marsh Type II in 2 and Type III in 3. Of these 5 diagnosed CD patients, 4 (4/395, 1.01%) were from the IBS-D group and 1 (1/363, 0.28%) from the healthy control had asymptomatic CD. Two Type III CD patients with relatively high titers in the serologic assay were homozygous and heterozygous for haplotype HLA-DQA1*03-DQB1*03:03 (HLA-DQ9.3), respectively.In the present study, CD was present in 1.01% of patients with IBS-D and in 0.28% of the control group. We like to suggest that the haplotype HLA-DQA1*03-DQB1*03:03 (HLA-DQ9.3), which is common in Chinese, is a new susceptibility factor for CD in China. Larger screening and genetic studies are needed in the Chinese population of different regions. PMID:26496305

  6. The effect of obesity levels on irradiated small bowel volume in belly board with small bowel displacement device for rectal cancer radiotherapy

    International Nuclear Information System (INIS)

    For radiotherapy in rectal cancer patients treated with small bowel displacement device (SBDD) and belly board, We will suggest new indication of using SBDD depending on obesity index by analyzing correlation between obesity and irradiated small bowel volume. In this study, We reviewed 29 rectal cancer patients who received pelvic radiation therapy with belly board and SBDD from January to April in 2012. We only analyzed those patients treated with three-field technique (PA and both LAT) on 45 Gy (1.8 Gy/fx). We measured patients' height, weight, body mass index (BMI), waist-hip ratio (WHR) and divided BMI into two groups.(≥23:BMI=group 1, <23:BMI=group 2) We performed a statistical analysis to evaluate correlation between total volume of bladder (TVbldder), obesity index and high dose volume of small bowel (small bowel volume irradiated at 90% of prescribed dose, HDVsb), low dose volume of small bowel (small bowel volume irradiated at 33% of prescribed dose, LDVsb). The result shows, gender, WHR and status of pre operative or post operative do not greatly affect HDVsb and LDVsb. Statistical result shows, there are significant correlation between HDVsb and BMI (p<0.04), HDVsb and TVbladder (p<0.01), LDVsb and TVbladder (p<0.01). BMI seems to correlate with HDVsb but does not with LDVsb (p>0.05). There are negative correlation between HDVsb and BMI, TVbladder and HDVsb, TVbladder and LDVsb . Especially, BMI group1 has more effective and negative correlation with HDVsb (p=0.027) than in BMI group 2. In the case of BMI group 1, TVbladder has significant negative correlation with HDVsb and LDVsb (p<0.04). In conclusions, we confirmed that Using SBDD with belly board in BMI group 1 could more effectively reduce irradiated small bowel volume in radiation therapy for rectal cancer. Therefore, We suggest using belly board with SBDD in order to reduce the small bowel toxicity in rectal radiotherapy, if patients' BMI is above 23

  8. Fecal DNA Screening in Colorectal Cancer

    Full Text Available Colorectal cancer (CRC is the third most common type of cancer diagnosed in Canada, and is the leading cause of cancer-related deaths in nonsmokers. Although CRC is considered to be 90% curable if detected early, the majority of patients present with advanced stage III or IV disease. An effective screening test may significantly decrease disease burden. The present paper examines the rationale and potential of fecal DNA testing as an alternative and adjunct to other CRC screening tests. The most efficacious fecal DNA test developed to date has a sensitivity and specificity of 87.5% and 82%, respectively. The approach has a higher positive predictive value than the currently used fecal occult blood test and offers a noninvasive option to patients. It is not reliant on the presence of bleeding, which may be intermittent or altogether absent. The test is now commercially available and is supported by a number of American insurers. Current challenges include cost reduction and demonstration of mortality benefit in a rigorous clinical trial. Despite current challenges, fecal DNA testing is worth pursuing. Both the American Gastroenterological Society and the American Cancer Society maintain that molecular testing is in its infancy but is promising. Fecal DNA testing has the potential to be an exciting addition to the current armament of CRC screening options.

  9. Techniques for restoring bowel continuity and function after rectal cancer surgery

    A very low local recurrence rate of 3%-6% (associated with improved 5 year survival) is possible when proper oncological surgery is performed of mid and distal rectal adenocarcinoma. Restoration of bowel continuity is possible in most cases, without compromise of cancer clearance. Re-anastomosis can be performed with stapled, transabdominal hand-sewn or coloanal pullthrough techniques. However after a direct (straight)anastomosis of the colon to the distal rectum/anus, up to 33% of patients have 3 or more bowel movements/d; some can be troubled with up to 14 stools a day.Construction of a 6-cm colonic J-pouch is likely to cause some reversed peristalsis which improves postoperative bowel frequency without causing neo-rectum evacuation problems. Colonic J-pouch-anal anastomosis patients have a median of 3 bowel movements a day compared with a median of 6 a day for straight anastomoses, at 1year after surgery. In the longer term, bowel adaptation may enable the function after a straight anastomosis to approximate that of a colonic J-pouch-anal anastomosis.This probably depends in the former, upon whether the more rigid sigmoid colon or more distensible descending colon is used. An additional advantage of the colonic J-pouch-anal anastomosis is the lower risk of anastomotic complications. A more vascularized side-toend (colonic J-pouch-anal) anastomosis is likely to heal better than an end-to-end (straight) anastomosis. Where the pelvis is too narrow for a bulky colonic J-pouch anal anastomosis, a coloplasty-anal-anastomosis is an option. The latter results in postoperative bowel function comparable with the colonic J-pouch. However, the risk of anastomotic complications is higher possibly related to its end-to-end anastomotic configuration. Laparoscopic techniques for accomplishing all the above are being proven to be effective. Restorative surgery for rectal cancer can be safely and effectively performed with methods to improve bowel tunction very acceptably; the

    BACKGROUND: In Ireland, colorectal cancer (CRC) is the second most frequently diagnosed cancer in men, after prostate cancer, and the second most frequently diagnosed cancer in women, after breast cancer. By 2020, the number of new cases diagnosed annually in Ireland is projected to have increased by 79% in men and 56% in women. Organised screening for CRC is already underway or is in the process of being rolled out in several European countries, either at a regional or national level. The Adelaide and Meath Hospital\\/ Trinity College Dublin Colorectal Cancer Screening Programme (TTC-CRC-SP) is Ireland\\'s first pilot population based bowel screening programme. METHOD: Based on a biennial test model the pilot aimed to assess the accuracy of FIT and to evaluate the whole programme based on established international key performance indices. RESULTS: To date 9,993 individuals aged 50-74 years have been invited to participate in the TTC-CRC-SP with over 5,000 FIT\\'s analysed. Overall uptake was 51% and FIT positivity was 10%. The programme has undertaken over 400 screening colonoscopies and detected 154 precancerous adenomas and 38 cancerous lesions. CONCLUSIONS: The first round of The Adelaide and Meath Hospital Tallaght\\/Trinity College Dublin Colorectal Cancer Screening Programme has been highly successful and confirmed that there is an advantage for FIT based two stage bowel cancer screening programmes.

    Breast cancer incidence and mortality rates are increasing in the Arab world and the involved women are often diagnosed at advanced stages of breast cancer. This literature review explores factors influencing Arab women's breast cancer screening behavior. Searched databases were: Medline, PubMed, Cochrane Database of Systematic Reviews, CINAHL Plus, Google Scholar, Index Medicus for WHO Eastern Mediterranean, and Asian Pacific Journal of Cancer Prevention. Breast cancer screening participation rates are low. Screening programs are opportunistic and relatively new to the region. Knowledge amongst women and health care providers, professional recommendation, socio-demographic factors, cultural traditions, beliefs, religious, social support, accessibility and perceived effectiveness of screening influence screening behavior.

    Lung cancer is the leading cause of cancer-related death worldwide. In 2011, the largest lung cancer screening trial worldwide, the US National Lung Screening Trial, published a 20% decrease in lung cancer-specific mortality in the computed tomography (CT)-screened group, compared with the group screened by chest x-ray. On the basis of this trial, different US guidelines recently have recommended CT lung cancer screening. However, several questions regarding the implementation of lung cancer screening need to be answered. In Europe, several lung cancer screening trials are ongoing. It is planned to pool the results of the lung cancer screening trials in European randomized lung cancer CT screening (EUCT). By pooling of the data, EUCT hopes to be able to provide additional information for the discussion of some important issues regarding the implementation of lung cancer screening by low-dose CT, including: the determination of the optimal screen population, the comparison between a volume-based and diameter-based nodule management protocol, and the determination of optimal screen intervals.

    Since the major reviews on diet and cancer by the World Cancer Research Fund (WCRF) and by the British Department of Health's Committee on Medical Aspects of Food Policy (COMA) in 1997 and 1998, additional epidemiological studies relating (red) meat consumption and colorectal cancer have been published or found by search. These are collected here. Thirty adequate case-control studies have been published up to 1999 (from 16 different countries). Twenty of them found no significant association of (red) meat with colorectal cancer. Of the remaining 10 studies reporting an association, some obtained statistical significance only in rectal or colon cancers, another only in men, not women, or found a stronger association with pasta and rice, or used an inadequate food list in the food frequency questionnaire. Fifteen cohort studies have now been published. Only in three were significant associations of (red) meat found with colorectal cancer. Two of these positive studies were from the same group in the USA (relative risk 1.7). The results of the third positive study appear to conflict with data from part of the vegetarians follow up mortality study. Here, five groups of vegetarians (in three different countries) with socially matched controls were followed up (total 76 000 people). Mortality from colorectal cancer was not distinguishable between vegetarians and controls. While it is still possible that certain processed meats or sausages (with a variety of added ingredients) or meats cooked at very high temperature carry some risk, the relationship between meats in general and colorectal cancer now looks weaker than the 'probable' status it was judged to have by the WCRF in 1997.

    2012-01-01

    Full Text Available Despite multiple screening techniques, including colonoscopy, flexible sigmoidoscopy, radiological imaging, and fecal occult blood testing, colorectal cancer remains a leading cause of death. As these techniques improve, their sensitivity to detect malignant lesions is increasing; however, detection of precursor lesions remains problematic and has generated a lack of general acceptance for their widespread usage. Early detection by an accurate, noninvasive, cost-effective, simple-to-use screening technique is central to decreasing the incidence and mortality of this disease. Recent advances in the development of molecular markers in faecal specimens are encouraging for its use as a screening tool. Genetic mutations and epigenetic alterations that result from the carcinogenetic process can be detected by coprocytobiology in the colonocytes exfoliated from the lesion into the fecal matter. These markers have shown promising sensitivity and specificity in the detection of both malignant and premalignant lesions and are gaining popularity as a noninvasive technique that is representative of the entire colon. In this paper, we summarize the genetic and epigenetic fecal molecular markers that have been identified as potential targets in the screening of colorectal cancer.

    Full Text Available Abstract Background Limited evidence suggests that people from non-English speaking backgrounds in Australia have lower than average rates of participation in cancer screening programs. The objective of this study was to examine the distribution of bowel, breast and prostate cancer test use by place of birth and years since migration in a large population-based cohort study in Australia. Methods In 2006, screening status, country of birth and other demographic and health related factors were ascertained by self-completed questionnaire among 31,401 (16,126 women and 15,275 men participants aged 50 or over from the 45 and Up Study in New South Wales. Results 35% of women and 39% of men reported having a bowel cancer test and 57% of men reported having a prostate specific antigen (PSA test, in the previous 5 years. 72% of women reported having screening mammography in the previous 2 years. Compared to Australian-born women, women from East Asia, Southeast Asia, Continental Western Europe, and North Africa/Middle East had significantly lower rates of bowel testing, with odds ratios (OR; 95%CI ranging from 0.5 (0.4–0.7 to 0.7 (0.6–0.9; migrants from East Asia (0.5, 0.3–0.7 and North Africa/Middle East (0.5, 0.3–0.9 had significantly lower rates of mammography. Compared to Australian-born men, bowel cancer testing was significantly lower among men from all regions of Asia (OR, 95%CI ranging from 0.4, 0.3–0.6 to 0.6, 0.5–0.9 and Continental Europe (OR, 95%CI ranging from 0.4, 0.3–0.7 to 0.7, 0.6–0.9. Only men from East Asia had significantly lower PSA testing rates than Australian-born men (0.4, 0.3–0.6. As the number of years lived in Australia increased, cancer test use among migrants approached Australian-born rates. Conclusion Certain migrant groups within the population may require targeted intervention to improve their uptake of cancer screening, particularly screening for bowel cancer.

Clinical management of MBO requires a specific and individualized approach that is based on disease prognosis and the objectives of care. The global prevalence of MBO is estimated to be 3% to 15% of cancer patients. Surgery should always be considered for patients in the initial stages of the disease with a preserved general status and a single level of occlusion. Less invasive approaches such as duodenal or colonic stenting should be considered when surgery is contraindicated in obstructions at the single level. The priority of care for inoperable and consolidated MBO is to control symptoms and promote the maximum level of comfort possible. The spontaneous resolution of an inoperable obstructive process is observed in more than one third of patients. The mean survival is of no longer than 4–5 weeks in patients with consolidated MBO. Polymodal medical treatment based on a combination of glucocorticoids, strong opioids, antiemetics, and antisecretory drugs achieves very high symptomatic control. This review focuses on the epidemiological aspects, diagnosis, surgical criteria, medical management, and factors influencing the spontaneous resolution of MBO in advanced cancer patients.Keywords: malignant bowel obstruction, cancer, intestinal obstruction, bowel occlusion

    Multiple advisory groups now recommend that high-risk smokers be screened for lung cancer by low-dose computed tomography. Given that the development of lung cancer screening programs will face many of the same issues that have challenged other cancer screening programs, the National Cancer Institute-funded Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) consortium was used to identify lessons learned from the implementation of breast, cervical, and colorectal cancer screening that should inform the introduction of lung cancer screening. These lessons include the importance of developing systems for identifying and recruiting eligible individuals in primary care, ensuring that screening centers are qualified and performance is monitored, creating clear communication standards for reporting screening results to referring physicians and patients, ensuring follow-up is available for individuals with abnormal test results, avoiding overscreening, remembering primary prevention, and leveraging advances in cancer genetics and immunology. Overall, this experience emphasizes that effective cancer screening is a multistep activity that requires robust strategies to initiate, report, follow up, and track each step as well as a dynamic and ongoing oversight process to revise current screening practices as new evidence regarding screening is created, new screening technologies are developed, new biological markers are identified, and new approaches to health care delivery are disseminated.

    Each state is autonomous in its comprehensive cancer control (CCC) program, and considerable heterogeneity exists in the program plans. However, researchers often focus on the concept of nationally representative data and pool observations across states using regression analysis to come up with average effects when interpreting results. Due to considerable state autonomy and heterogeneity in various dimensions-including culture, politics, historical precedent, regulatory environment, and CCC efforts-it is important to examine states separately and to use geographic analysis to translate findings in place and time. We used 100 percent population data for Medicare-insured persons aged 65 or older and examined predictors of breast cancer (BC) and colorectal cancer (CRC) screening from 2001-2005. Examining BC and CRC screening behavior separately in each state, we performed 100 multilevel regressions. We summarize the state-specific findings of racial disparities in screening for either cancer in a single bivariate map of the 50 states, producing a separate map for African American and for Hispanic disparities in each state relative to whites. The maps serve to spatially translate the voluminous regression findings regarding statistically significant disparities between whites and minorities in cancer screening within states. Qualitative comparisons can be made of the states' disparity environments or for a state against a national benchmark using the bivariate maps. We find that African Americans in Michigan and Hispanics in New Jersey are significantly more likely than whites to utilize CRC screening and that Hispanics in 6 states are significantly and persistently more likely to utilize mammography than whites. We stress the importance of spatial translation research for informing and evaluating CCC activities within states and over time. PMID:24944346

    Full Text Available Objective. Vietnamese American women are at the greatest risk for cervical cancer but have the lowest cervical cancer screening rates. This study was to determine whether demographic and acculturation, healthcare access, and knowledge and beliefs are associated with a prior history of cervical cancer screening among Vietnamese women. Methods. Vietnamese women (n=1450 from 30 Vietnamese community-based organizations located in Pennsylvania and New Jersey participated in the study and completed baseline assessments. Logistic regression analyses were performed. Results. Overall levels of knowledge about cervical cancer screening and human papillomavirus (HPV are low. Factors in knowledge, attitude, and beliefs domains were significantly associated with Pap test behavior. In multivariate analyses, physician recommendation for screening and having health insurance were positively associated with prior screening. Conclusion. Understanding the factors that are associated with cervical cancer screening will inform the development of culturally appropriate intervention strategies that would potentially lead to increasing cervical cancer screening rates among Vietnamese women.

    Full Text Available Thyroid cancer incidence has increased significantly over the past three decades due, in part, to incidental detection. We examined the association between randomization to screening for lung, prostate, colorectal and/or ovarian cancers and thyroid cancer incidence in two large prospective randomized screening trials.We assessed the association between randomization to low-dose helical CT scan versus chest x-ray for lung cancer screening and risk of thyroid cancer in the National Lung Screening Trial (NLST. In the Prostate Lung Colorectal and Ovarian Cancer Screening Trial (PLCO, we assessed the association between randomization to regular screening for said cancers versus usual medical care and thyroid cancer risk. Over a median 6 and 11 years of follow-up in NLST and PLCO, respectively, we identified 60 incident and 234 incident thyroid cancer cases. Cox proportional hazards regression was used to calculate the cause specific hazard ratios (HR and 95% confidence intervals (CI for thyroid cancer.In NLST, randomization to lung CT scan was associated with a non-significant increase in thyroid cancer risk (HR = 1.61; 95% CI: 0.96-2.71. This association was stronger during the first 3 years of follow-up, during which participants were actively screened (HR = 2.19; 95% CI: 1.07-4.47, but not subsequently (HR = 1.08; 95% CI: 0.49-2.37. In PLCO, randomization to cancer screening compared with usual care was associated with a significant decrease in thyroid cancer risk for men (HR = 0.61; 95% CI: 0.49-0.95 but not women (HR = 0.91; 95% CI: 0.66-1.26. Similar results were observed when restricting to papillary thyroid cancer in both NLST and PLCO.Our study suggests that certain medical encounters, such as those using low-dose helical CT scan for lung cancer screening, may increase the detection of incidental thyroid cancer.

    Background Thyroid cancer incidence has increased significantly over the past three decades due, in part, to incidental detection. We examined the association between randomization to screening for lung, prostate, colorectal and/or ovarian cancers and thyroid cancer incidence in two large prospective randomized screening trials. Methods We assessed the association between randomization to low-dose helical CT scan versus chest x-ray for lung cancer screening and risk of thyroid cancer in the National Lung Screening Trial (NLST). In the Prostate Lung Colorectal and Ovarian Cancer Screening Trial (PLCO), we assessed the association between randomization to regular screening for said cancers versus usual medical care and thyroid cancer risk. Over a median 6 and 11 years of follow-up in NLST and PLCO, respectively, we identified 60 incident and 234 incident thyroid cancer cases. Cox proportional hazards regression was used to calculate the cause specific hazard ratios (HR) and 95% confidence intervals (CI) for thyroid cancer. Results In NLST, randomization to lung CT scan was associated with a non-significant increase in thyroid cancer risk (HR  = 1.61; 95% CI: 0.96–2.71). This association was stronger during the first 3 years of follow-up, during which participants were actively screened (HR  = 2.19; 95% CI: 1.07–4.47), but not subsequently (HR  = 1.08; 95% CI: 0.49–2.37). In PLCO, randomization to cancer screening compared with usual care was associated with a significant decrease in thyroid cancer risk for men (HR  = 0.61; 95% CI: 0.49–0.95) but not women (HR  = 0.91; 95% CI: 0.66–1.26). Similar results were observed when restricting to papillary thyroid cancer in both NLST and PLCO. Conclusion Our study suggests that certain medical encounters, such as those using low-dose helical CT scan for lung cancer screening, may increase the detection of incidental thyroid cancer.

    Full Text Available The relationship between obesity and cancer screening varies by screening test, race, and gender. Most studies on cervical cancer screening found a negative association between increasing weight and screening, and this negative association was most consistent in white women. Recent literature on mammography reports no association with weight. However, some studies show a negative association in white, but not black, women. In contrast, obese/overweight men reported higher rates of prostate-specific antigen (PSA testing. Comparison of prostate cancer screening, mammography, and Pap smears implies a gender difference in the relationship between screening behavior and weight. In colorectal cancer (CRC screening, the relationship between weight and screening in men is inconsistent, while there is a trend towards lower CRC screening in higher weight women.

    At the beginning of the 20th Century, cervical cancer was the leading cause of death from cancer in women. A marked decline in cervical cancer has been observed since the 1960s, in parallel with the introduction of the Papanicolau (Pap) test as a cytological screening method. Today, Pap smear screening is still the most widely used tool for cervical cancer prevention. Testing for human papillomavirus (HPV) in cervical specimens or a combination of Pap and HPV testing are also now available. In this article we compare current guidelines for cervical cancer screening in Switzerland with those in other European countries. In view of the opportunities offered by HPV testing and, since 2008, HPV vaccination, current guidelines for cervical cancer screening should be updated. Both the choice of screening tests and general organization of cervical cancer screening should be reviewed.

  10. Bowel, Urinary, and Sexual Problems Among Long-Term Prostate Cancer Survivors: A Population-Based Study

    International Nuclear Information System (INIS)

    Purpose: To obtain insight into the long-term (5- to 10-year) effects of prostate cancer and treatment on bowel, urinary, and sexual function, we performed a population-based study. Prostate-specific function was compared with an age-matched normative population without prostate cancer. Methods and Materials: Through the population-based Eindhoven Cancer Registry, we selected all men diagnosed with prostate cancer between 1994 and 1998 in the southern Netherlands. In total, 964 patients, alive in November 2004, received questionnaire; 780 (81%) responded. Results: Urinary problems were most common after a prostatectomy; bowel problems were most common after radiotherapy. Compared with an age-matched normative population both urinary and bowel functioning and bother were significantly worse among survivors. Urinary incontinence was reported by 23-48% of survivors compared with 4% of the normative population. Bowel leakage occurred in 5-14% of patients compared with 2% of norms. Erection problems occurred in 40-74% of patients compared with 18% of norms. Conclusions: These results form an important contribution to the limited information available on prostate-specific problems in the growing group of long-term prostate cancer survivors. Bowel, urinary, and sexual problems occur more often among long-term survivors compared with a reference group and cannot be explained merely by age. Because these problems persist for many years, urologists should provide patients with adequate information before treatment. After treatment, there should be an appropriate focus on these problems

    Several important lessons have been learnt from our experiences in screening for various cancers. Screening programmes for cervical and colorectal cancers have had the greatest success, probably because these cancers are relatively homogenous, slow-growing, and have identifiable precursors that can be detected and removed; however, identifying the true obligate precursors of invasive disease remains a challenge. With regard to screening for breast cancer and for prostate cancer, which focus on early detection of invasive cancer, preferential detection of slower-growing, localized cancers has occurred, which has led to concerns about overdiagnosis and overtreatment; programmes for early detection of invasive lung cancers are emerging, and have faced similar challenges. A crucial consideration in screening for breast, prostate, and lung cancers is their remarkable phenotypic heterogeneity, ranging from indolent to highly aggressive. Efforts have been made to address the limitations of cancer-screening programmes, providing an opportunity for cross-disciplinary learning and further advancement of the science. Current innovations are aimed at identifying the individuals who are most likely to benefit from screening, increasing the yield of consequential cancers on screening and biopsy, and using molecular tests to improve our understanding of disease biology and to tailor treatment. We discuss each of these concepts and outline a dynamic framework for continuous improvements in the field of cancer screening. PMID:27071351

    PURPOSE: To determine pre-operative MRI accuracy in assessing local disease extent in recurrent/residual pelvic bowel cancer by comparing MRI assessment and staging examination under anaesthesia (EUA), with laparotomy/histopathological findings. MATERIALS AND METHODS: Twenty-seven consecutive patients with recurrent (n = 21) or residual (n = 6) pelvic bowel cancer (13 of the rectum, eleven of the anus and three of the colon) underwent EUA and pelvic MRI (1T) using a phased array pelvic coil. Retrospective analysis of eight specific anatomical regions for tumour involvement on MRI was performed. Findings at EUA and biopsy were recorded. The MRI and EUA findings were correlated with findings at surgery and histopathology. Statistical comparison between MRI and EUA results was performed using the chi-squared test . RESULTS: Overall MRI accuracy in determining tumour invasion for all sites assessed was 452/499 (91%), sensitivity was 95/109 (87%), specificity was 357/390 (92%), positive predictive value (PPV) was 95/128 (74%) and negative predictive value (NPV) was 357/371 (96%). PPV and NPV for specific areas were 21/38 (55%) and 134/136 (99%) for genitourinary tract, 4/6 (67%) and 61/65 (94%) for pelvic side wall, 21/26 (81%) and 40/41 (98%) for pelvic floor, 1/6 (17%) and 40/43 (93%) for the posterior pelvis pre-sacrum/sacrum. For those anatomical sites evaluated by both EUA and MRI, MRI was superior to EUA, with an accuracy of 89% vs 73%(P < 0.05) . CONCLUSION: MRI is an accurate technique for assessing disease extent in recurrent/residual pelvic bowel cancer. Robinson, P. et al. (2002)

    Full Text Available Background. To determine why women skip rounds and factors influencing return of previous non attenders (PNAs to breast screening. Design and methods. Retrospective, quantitative, structured questionnaire posted to 2500 women. First PNAs did not attend their first screening appointment in 2007/2008 but then attended in 2010; First Controls first attended in 2010 without missed previous appointments. Women who attended screening in 2006 or earlier then skipped a round but returned in 2010 were Subsequent PNAs; Subsequent Controls attended all appointments.Results. More First Controls than First PNAs had family history of cancer (72.7% vs 63.2%; P=0.003; breast cancer (31.3% vs 24.8%; P=0.04. More PNAs lived rurally; more First PNAs had 3rd level education (33.2% vs 23.6%; P=0.002 and fewer had private insurance than First Controls (57.7% vs 64.8%; P=0.04. Excellent/good health was reported in First PNAs and First Controls (82.9% vs 83.2%, but fewer Subsequent PNAs than Subsequent Controls (72.7% vs 84.9%; P=0.000. Common considerations at time of missed appointment were had mammogram elsewhere (33% First PNA and postponed to next round (16% First PNA, 18.8% Subsequent PNA. Considerations when returning to screening were similar for First PNAs and Subsequent PNAs: I am older (35.4%, 29.6%, I made sure I remembered (29%, 23.6%, could reschedule (17.6%, 20.6%, illness of more concern (16.5%, 19%. More First PNAs stated my family/friends advised (22.3% vs 15.2% or my GP (12.6% vs 4.6% advised me to attend, heard good things about BreastCheck (28.8% vs 13.6%.Conclusions. Intermittent attenders do not fit socio-demographic patterns of non-attenders; GP recommendation and word of mouth were important in women’s return to screening. Fear and anxiety seem to act as a screening facilitator rather than an inhibitor.

  6. Public Awareness of Colorectal Cancer Screening: Knowledge, Attitudes, and Interventions for Increasing Screening Uptake

    2014-01-01

    Colorectal cancer ranks as one of the most incidental and death malignancies worldwide. Colorectal cancer screening has proven its benefit in terms of incidence and mortality reduction in randomized controlled trials. In fact, it has been recommended by medical organizations either in average-risk or family-risk populations. Success of a screening campaign highly depends on how compliant the target population is. Several factors influence colorectal cancer screening uptake including sociodemographics, provider and healthcare system factors, and psychosocial factors. Awareness of the target population of colorectal cancer and screening is crucial in order to increase screening participation rates. Knowledge about this disease and its prevention has been used across studies as a measurement of public awareness. Some studies found a positive relationship between knowledge about colorectal cancer, risk perception, and attitudes (perceived benefits and barriers against screening) and willingness to participate in a colorectal cancer screening campaign. The mentioned factors are modifiable and therefore susceptible of intervention. In fact, interventional studies focused on average-risk population have tried to increase colorectal cancer screening uptake by improving public knowledge and modifying attitudes. In the present paper, we reviewed the factors impacting adherence to colorectal cancer screening and interventions targeting participants for increasing screening uptake. PMID:24729896

    Full Text Available Abstract Background Data comparison between SEER and EUROCARE database provided evidence that colorectal cancer survival in USA is higher than in European countries. Since adjustment for stage at diagnosis markedly reduces the survival differences, a screening bias was hypothesized. Considering the important role of primary care in screening activities, the purpose of the study was to investigate the colorectal cancer screening awareness among Hellenic physicians. Methods 211 primary care physicians were surveyed by mean of a self-reported prescription-habits questionnaire. Both physicians' colorectal cancer screening behaviors and colorectal cancer screening recommendations during usual check-up visits were analyzed. Results Only 50% of physicians were found to recommend screening for colorectal cancer during usual check-up visits, and only 25% prescribed cost-effective procedures. The percentage of physicians recommending stool occult blood test and sigmoidoscopy was 24% and 4% respectively. Only 48% and 23% of physicians recognized a cancer screening value for stool occult blood test and sigmoidoscopy. Colorectal screening recommendations were statistically lower among physicians aged 30 or less (p = 0.012. No differences were found when gender, level and type of specialization were analyzed, even though specialists in general practice showed a trend for better prescription (p = 0.054. Conclusion Contemporary recommendations for colorectal cancer screening are not followed by implementation in primary care setting. Education on presymptomatic control and screening practice monitoring are required if primary care is to make a major impact on colorectal cancer mortality.

    Colorectal cancer (CRC) has the second highest cancer prevalence and mortality rates in Australia. The Australian National Bowel Cancer Screening Program (NBCSP) aims to increase early detection of CRC by offering free faecal occult blood testing. The NBCSP aims to offer choice to consumers about whether or not to participate in screening. This article presents data on trust, choice and perceived obligation to participate in the NBCSP by population groups with low uptake. A qualitative study was undertaken in South Australia. We interviewed 94 people from four culturally distinct groups: Greek, Iranian, Anglo-Australian and Indigenous peoples. This article demonstrates the complexity of factors shaping the choice, or lack thereof, to participate in the NBCSP. Informed choice is based on adequate knowledge, although this varied among our participants, highlighting the need for more health education in appropriate languages. An obligation to participate was found in the Iranian and Anglo-Australian groups and resulted from an established personal relationship with the doctor, a sense of duty, the acknowledgement of government investment and appreciation. Overall, this article makes a link between trust, choice and obligation, adding to literature on the sociology of trust and medical screening and highlighting important issues in the need of a policy and practice to improve CRC screening rates.

    Directory of Open Access Journals (Sweden)

    Full Text Available The most common incipit of papers published regarding exocrine pancreatic neoplasms is that pancreatic cancer is one of the most lethal cancers, with a rate of incidence equal to that of mortality. Pancreatic cancer is a heterogeneous group of neoplasms in which pancreatic ductal adenocarcinoma is the most common. For the most part, the problems related to the early diagnosis of pancreatic adenocarcinoma are three: 1 to better understand the biology of this tumor; 2 to better investigate the precursors of this tumor; and 3 to plan projects for pancreatic cancer screening in high-risk individuals. Recently, Yachida et al. [1] performed rapid autopsies on seven individuals with Stage IV pancreatic cancer and they found that the clonal populations which give rise to distant metastases are represented within the primary carcinoma, but these clones are genetically evolved from the original parental, non-metastatic clone. Thus, the genetic heterogeneity of the metastases reflects that of the primary carcinoma. Most important, when the authors performed a quantitative analysis of the timing of the genetic evolution of pancreatic cancer, they found that there was at least a decade between the occurrence of the initial mutation and the birth of the parental, non-metastatic founder cell. At least five more years are required for the acquisition of metastatic ability and patients die an average two years thereafter. As underscored by the authors, these data have an important implication in planning population screening for the purpose of preventing pancreatic cancer deaths: in fact, quantitative analysis indicated a large window, of at least a decade, in which the disease could be diagnosed while it is still in the curative stage. This model also predicts an average of 6.8 years between the birth of the cell giving rise to the parental clone and the seeding of the index metastasis.

    Pre or postoperative pelvic irradiation has demonstrated a definitive efficacy in reducing the local failure rate of rectal cancer treated with surgery alone. However it can induce late small bowel morbidity that could alter the therapeutic ratio. The clinical pictures of radiation enteritis include obstruction and diarrhea/malabsorption. Prognostic factors that increase the risk of late small bowel complications include extended fields out of the pelvis, irradiation dose, inappropriate irradiation technique, and increased small bowel irradiated volumes. The addition of chemotherapy increases acute but not late toxicity. Recommendations concerning the clinical practice are describes. Radiotherapy may also alter the residual sphincter function and we recommend to assess correctly these complications. (authors)

    Full Text Available Prostate cancer is highly prevalent in Jamaica and is the leading cause of cancer-related deaths. Our aim was to evaluate the patterns of screening in the largest organized screening clinic in Jamaica at the Jamaica Cancer Society. A retrospective analysis of all men presenting for screening at the Jamaica Cancer Society from 1995 to 2005 was done. All patients had digital rectal examinations (DRE and prostate specific antigen (PSA tests done. Results of prostate biopsies were noted. 1117 men of mean age 59.9 ± 8.2 years presented for screening. The median documented PSA was 1.6 ng/mL (maximum of 5170 ng/mL. Most patients presented for only 1 screen. There was a gradual reduction in the mean age of presentation for screening over the period. Prostate biopsies were requested on 11% of screening visits; however, only 59% of these were done. 5.6% of all persons screened were found to have cancer. Of the cancers diagnosed, Gleason 6 adenocarcinoma was the commonest grade and median PSA was 8.9 ng/mL (range 1.5–1059 ng/mL. Older men tend to screen for prostate cancer in Jamaica. However, compliance with regular maintenance visits and requests for confirmatory biopsies are poor. Screening needs intervention in the Jamaican population.

  16. Results and analysis of screening for breast cancer

    International Nuclear Information System (INIS)

    Breast cancer is the most frequent cause of death in most countries of the world. Screening of asymptomatic women can detect a large percentage of cancers at an early stage. This is the basis for a possible cure or at least a prolongation of the survival time. The percentage of minimal cancers (smaller than 1 cm without dissemination) may be as high as 48% depending on the screening modality (10% without screening), axillary lymph node involvement can be reduced to 20% (40% without screening), and the percentage of stage II to IV cancers can be reduced to 8-20% (60% without screening). Mortality in the study group over age 50 years was reduced by 30%. Disadvantages of screening are: high cost; biopsies prompted by false positive results; psychological stress for the patients; radiation hazards which have, however, become almost negligible thanks to improved technique (2 cancers in 1 million mammographies and year).

Screening mammography has been shown to be effective in reducing breast cancer mortality in women aged 50–74 years but not among those aged 75 years or older. Given the large heterogeneity in comorbidity status and life expectancy among older women, controversy remains over screening mammography in this population. Diminished life expectancy with aging may decrease the potential screening benefit and increase the risk of harms. In this review, we summarize the evidence on screening mammography utilization, performance, and outcomes and highlight evidence gaps. Optimizing the screening strategy will involve separating older women who will benefit from screening from those who will not benefit by using information on comorbidity status and life expectancy. This review has identified areas related to screening mammography in older women that warrant additional research, including the need to evaluate emerging screening technologies, such as tomosynthesis among older women and precision cancer screening. In the absence of randomized controlled trials, the benefits and harms of continued screening mammography in older women need to be estimated using both population-based cohort data and simulation models.

    The poor outcomes for cancers diagnosed at an advanced stage have been the driver behind research into techniques to detect disease before symptoms are manifest. For cervical and colorectal cancer, detection and treatment of "precancers" can prevent the development of cancer, a form of primary prevention. For other cancers-breast, prostate, lung, and ovarian-screening is a form of secondary prevention, aiming to improve outcomes through earlier diagnosis. International and national expert organizations regularly assess the balance of benefits and harms of screening technologies, issuing clinical guidelines for population-wide implementation. Psychological research has made important contributions to this process, assessing the psychological costs and benefits of possible screening outcomes (e.g., the impact of false positive results) and public tolerance of overdiagnosis. Cervical, colorectal, and breast screening are currently recommended, and prostate, lung, and ovarian screening are under active review. Once technologies and guidelines are in place, delivery of screening is implemented according to the health care system of the country, with invitation systems and provider recommendations playing a key role. Behavioral scientists can then investigate how individuals make screening decisions, assessing the impact of knowledge, perceived cancer risk, worry, and normative beliefs about screening, and this information can be used to develop strategies to promote screening uptake. This article describes current cancer screening options, discusses behavioral research designed to reduce underscreening and minimize inequalities, and considers the issues that are being raised by informed decision making and the development of risk-stratified approaches to screening.

  1. Targeted Cancer Screening in Average-Risk Individuals.

    2015-11-01

    Targeted cancer screening refers to use of disease risk information to identify those most likely to benefit from screening. Researchers have begun to explore the possibility of refining screening regimens for average-risk individuals using genetic and non-genetic risk factors and previous screening experience. Average-risk individuals are those not known to be at substantially elevated risk, including those without known inherited predisposition, without comorbidities known to increase cancer risk, and without previous diagnosis of cancer or pre-cancer. In this paper, we describe the goals of targeted cancer screening in average-risk individuals, present factors on which cancer screening has been targeted, discuss inclusion of targeting in screening guidelines issued by major U.S. professional organizations, and present evidence to support or question such inclusion. Screening guidelines for average-risk individuals currently target age; smoking (lung cancer only); and, in some instances, race; family history of cancer; and previous negative screening history (cervical cancer only). No guidelines include common genomic polymorphisms. RCTs suggest that targeting certain ages and smoking histories reduces disease-specific cancer mortality, although some guidelines extend ages and smoking histories based on statistical modeling. Guidelines that are based on modestly elevated disease risk typically have either no or little evidence of an ability to affect a mortality benefit. In time, targeted cancer screening is likely to include genetic factors and past screening experience as well as non-genetic factors other than age, smoking, and race, but it is of utmost importance that clinical implementation be evidence-based.

  14. Anal cancer and intraepithelial neoplasia screening: A review.

    Science.gov (United States)

    Leeds, Ira L; Fang, Sandy H

    2016-01-27

    This review focuses on the early diagnosis of anal cancer and its precursor lesions through routine screening. A number of risk-stratification strategies as well as screening techniques have been suggested, and currently little consensus exists among national societies. Much of the current clinical rationale for the prevention of anal cancer derives from the similar tumor biology of cervical cancer and the successful use of routine screening to identify cervical cancer and its precursors early in the disease process. It is thought that such a strategy of identifying early anal intraepithelial neoplasia will reduce the incidence of invasive anal cancer. The low prevalence of anal cancer in the general population prevents the use of routine screening. However, routine screening of selected populations has been shown to be a more promising strategy. Potential screening modalities include digital anorectal exam, anal Papanicolaou testing, human papilloma virus co-testing, and high-resolution anoscopy. Additional research associating high-grade dysplasia treatment with anal cancer prevention as well as direct comparisons of screening regimens is necessary to develop further anal cancer screening recommendations.

    Lung cancer is the leading cause of cancer death worldwide. Age and smoking are the primary risk factors for lung cancer. Treatment based on surgical removal in the early stages of the disease results in better survival. Screening programmes for early detection that used chest radiography and sputum cytology failed to attain reduction of lung cancer mortality. Screening by low-dose computed tomography (CT) demonstrated high rates of early-stage lung cancer detection in a high-risk population. Nevertheless, no mortality advantage was manifested in small randomised control trials. A large randomised control trial in the U.S.A., the National Lung Screening Trial (NLST), showed a significant relative reduction of 20% in lung cancer mortality and 6.7% reduction in total mortality, yet no reduction was evidenced in the late-stage prevalence. Screening for lung cancer by low-dose CT reveals a high level of false-positive lesions, which necessitates further noninvasive and invasive evaluations. Based primarily on the NLST eligible criteria, new guidelines have recently been developed by major relevant organisations. The overall recommendation coming out of this collective work calls for lung cancer screening by low-dose CT to be performed in medical centres manned by specialised multidisciplinary teams, as well as for a mandatory, pre-screening, comprehensive discussion with the patient about the risks and advantages involved in the process. Lung cancer screening is on the threshold of a new era, with ever more questions still left open to challenge future studies.

    Martin C S Wong

    Full Text Available PURPOSE: to evaluate the proportion of self-referred screening participants having various psychological barriers and the factors associated with these barriers. METHODS: A territory-wide bowel cancer screening centre sent an invitation via the media to all Hong Kong residents aged 50-70 years who were asymptomatic of CRC to join a free screening programme. Upon attendance they were requested to complete self-administered surveys on their perceived barriers of screening. Binary logistic regression analyses were used to evaluate the factors associated with these barriers. RESULTS: From 10,078 consecutive screening participants (mean age 57.5 years; female 56.4% completed the surveys between May 2008 to September 2012. There were high proportions who agreed or strongly agreed with the following barriers: financial difficulty (86.0%, limited service accessibility (58.2%, screening-induced bodily discomfort (55.2%, physical harm (44.4%, embarrassment (40.1%, apprehension (38.8% and time constraints (13.9%. From regression models, older participants (aged ≥ 56 were less likely to have these barriers (Adjusted odds ratio [AOR] ranged from 0.738 to 0.952 but they encountered more difficulties to access to screening services (AOR ranged from 1.141 to 1.371. Female subjects were more likely to encounter most of these barriers (AOR ranged from 1.188 to 2.179. Participants who were uncertain of the necessity of CRC screening for people aged ≥ 50 were more likely to report these barriers (AOR ranged from 1.151 to 1.671. CONCLUSION: The proportions of perceptual barriers of CRC screening were high among these participants. Those with these associated factors should receive more thorough explanation of the screening test procedures.

    Lung cancer is a commonly occurring cancer among Korean American men. Korean Americans have lower rates of cancer screening participation than other Asian American sub-groups. However, little is known about factors that influence the cancer screening behavior of Korean immigrants. The purpose of this study was to explore facilitators of and barriers to lung cancer screening (i.e., low dose CT of the chest) among Korean immigrant men, using qualitative individual interviews and focus groups. A convenience sample of 24 Korean men who were immigrants, Washington State residents, able to speak Korean, aged 55-79, and eligible for lung cancer screening (based on current guidelines) were recruited from Korean churches and senior centers. Five focus groups (that included between two and five men) and nine individual interviews were conducted. Content analysis was used to analyze the qualitative data. Facilitators of lung cancer screening included perceptions about positive aspects of the health care system in South Korea, recommendations from others (physicians, family members, and community organizations), existing health problems and respiratory symptoms, interest in health, and the health consequences of aging. Barriers included costs of health care in the US, lack of time, lack of knowledge (about lung cancer and screening), attitudes about prevention, and lack of physician recommendation. This study adds new knowledge to a field where little information is available. It also lays the groundwork for developing culturally relevant lung cancer screening interventions for Korean Americans and the health care providers who serve them. PMID:26846627

In USA, there are more than 30.000 new cases every year. We can find many risk factors of oral cancer in our daily living. Moreover, it’s easy to find the main risk factors in our society, they are smoking, alcohol consumption, tobacco consumtion, viral infection, and bad oral hygiene. For the early stadium, Five-years survival rate is about 82% and 61% for all stadium. But, more than 50% of oral cancer has been distributed (metastatic regionally and also into the other organ far away from the oral itself when it’s detected. It will decrease 5-years survival rate to be less than 50%. So that, it’s really important to detect the oral cancer at the earlier stadium. Screening is the way to find the earlier stadium. Screening is done by some methods, start from the anamnesis, physical examination, toluidine blue staining, endoscopy, cytology, telomerase examination, and also PET-scan if it’s possible (because of the financial reasons. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

    2011-06-01

    Full Text Available As one of the four major functions of health systems, Stewardship is on the health agenda of several countries worldwide. There is, however, little empirical evidence to support or guide its implementation. To help bridge this gap, the paper aims to contribute to the empirical evidence for health system stewardship and, importantly, to offer implementers an explanatory example of what it could mean in practice. It achieves this by analyzing the experience of the Italian Cancer Screening Programs (from 2004-2009 within a comprehensive framework for health system stewardship. The analysis is largely based on primary and secondary qualitative data, using information collected from an in-depth interview, official documents, and scientific and grey literature. We describe the framework and sub-functions of stewardship, identify the stewardship activities that were carried out by the Programs, and reflect upon the operability of the framework as well as the activities that the Programs have not implemented but would benefit from doing so. The general experience and activities of the Italian Cancer Screening Programs fit well into the stewardship framework, despite not having followed it a priori. Overall, the Programs managed to implement most activities under each sub-function. As an empirical case study, they corroborated the theoretical framework and demonstrated how it could be translated into certain activities on an operational platform. Ultimately, the analysis showed that the framework of stewardship is useful for structuring and prioritizing the most important activities of a steward and, thus, provides a good benchmark for implementers.

    In January 2014, the first nationwide quality-assured breast cancer screening program addressing women aged ≥ 40 years was introduced in Austria. As part of the process of developing a patient information leaflet, the Evidence Based Medicine (EBM) Review Center of the Medical University of Graz was charged with the task of assessing the potential benefits and harms of breast cancer screening from the available evidence. Based on these results, key figures were derived for mortality, false-positive and false-negative mammography results, and overdiagnosis, considering Austria-specific incidence rates for breast cancer and breast cancer mortality. Furthermore, the current evidence regarding age limits and screening interval, which were the subjects of controversial public discussions, was analyzed. A systematic search for primary and secondary literature was performed and additional evidence was screened, e. g., evaluation reports of European breast cancer screening programs. On the basis of the available evidence and of the Austrian breast cancer mortality and incidence rates, it can be assumed that - depending on the age group - 1 to 4 breast cancer deaths can be avoided per 1,000 women screened in a structured breast cancer screening program, while the overall mortality remains unchanged. On the other hand, 150 to 200 of these 1,000 women will be affected by false-positive results and 1 to 9 women by overdiagnosis due to the structured breast cancer screening. Therefore, the overall benefit-harm balance is uncertain. If women from 40 to 44 or above 70 years of age are considered, who can also participate in the Austrian screening program, even a negative benefit-harm balance seems possible. However, with the implementation of quality standards in breast cancer screening and the dissemination of a patient information leaflet, an improvement in the medical treatment situation, specifically in terms of informed decision-making, can be expected.

    Full Text Available Abstract Background Australia has a comparatively high incidence of colorectal (bowel cancer; however, population screening uptake using faecal occult blood test (FOBT remains low. This study will determine the impact on screening participation of a novel, Internet-based Personalised Decision Support (PDS package. The PDS is designed to measure attitudes and cognitive concerns and provide people with individually tailored information, in real time, that will assist them with making a decision to screen. The hypothesis is that exposure to (tailored PDS will result in greater participation in screening than participation following exposure to non-tailored PDS or resulting from the current non-tailored, paper-based approach. Methods/design A randomised parallel trial comprising three arms will be conducted. Men and women aged 50-74 years (N = 3240 will be recruited. They must have access to the Internet; have not had an FOBT within the previous 12 months, or sigmoidoscopy or colonoscopy within the previous 5 years; have had no clinical diagnosis of bowel cancer. Groups 1 and 2 (PDS arms will access a website and complete a baseline survey measuring decision-to-screen stage, attitudes and cognitive concerns and will receive immediate feedback; Group 1 will receive information 'tailored' to their responses in the baseline survey and group 2 will received 'non-tailored' bowel cancer information. Respondents in both groups will subsequently receive an FOBT kit.

    Full Text Available Abstract Cervical cancer screening reduces morbidity and mortality due to cervical cancer. However, there are many factors that determine the success of any cervical cancer prevention effort: the prevalence of human papillomavirus infection in general population, the existence of an organized screening program and the corresponding coverage, the existence and quality of the field and laboratory facilities for screening and diagnostic follow-up, and the facilities available for treating diagnosed lesions. Monitoring the patient path or "chain of action" for each patient with an abnormal screening result is of crucial importance. Cost-effectiveness models are widely used by decision-makers to determine which cervical cancer screening program would maximize health benefits within a given, usually limited, set of resources. Regardless of their level of sophistication, however, these models cannot replace empirical evaluations of the effectiveness of screening programs. Cervical cancer prevention activities need to be monitored and evaluated in each country where they are introduced to see that they meet performance standards. Policy-makers responsible for allocating resources for cervical cancer prevention have a duty to allocate resources not only for cervical cancer screening, but also for screening program surveillance.

  9. Effectiveness of ultrasound for breast cancer screening

    International Nuclear Information System (INIS)

    To evaluate the effectiveness of ultrasound (US) for breast cancer screening, we conducted a retrospective survey of 856 breast cancer patients who were preoperatively examined by mammography (MMG) and US. Their average age was 54.7 years, with a range of 24 to 92 years. MMG revealed positive findings in 771 patients (90.1%), and negative findings in the remaining 85 patients (9.9%). Likewise, US revealed positive findings in 835 patients (97.5%), and negative findings in the remaining 21 patients (2.5%). Accordingly, the proportion of positive finding in US was significantly higher than that in MMG (chi-square test, p<0.0001). The incidence of negative findings with MMG was inversely related to age: 5.8% for patients in their 70s, 5.7% for those in their 60s, 8.3% for those in their 50s, 11.1% for those in their 40s, and 26.2% for those in their 30s or younger, because of the higher breast density in younger women (chi-square test, p<0.0001). The incidence of positive findings was 99.4% for tumors 2.1 to 3.0 cm in size, 96.3% for those measuring 1.6 to 2.0 cm, 94.3% for those measuring 1.1 to 1.5 cm, and 75.4% for those less than or equal to 1.0 cm (chi-square test, p<0.0001). Among the 85 patients with negative findings by MMG, 70(82.4%) were positive and 15 (17.6%) were negative by US. As findings of calcification by US, high echo spots plus a tumor lesion were observed in 59 patients (71.1%), high echo spots only were noted in 22 patients (26.5%), and high echo spots were not seen in 2 patients (2.4%). In conclusion, parallel use of MMG and US is recommended for breast cancer screening, especially for women in their 50s or younger, to reduce the incidence of misdiagnosis. (author)

    Recent guidelines from the American Cancer Society, the American Society for Colposcopy and Cervical Pathology, and the American Society for Clinical Pathology recommend cessation of cervical cancer screening at age 65 years for women with an "adequate" history of negative Papanicolaou smears. In our view, those who formulated these guidelines did not consider a growing body of evidence from nonrandomized studies that provides insight into the efficacy of cervical cancer screening among older women. First, older women are not at indefinitely low risk following negative screening results. Second, recent data from the United States, the United Kingdom, and Sweden suggest that screening of older women is associated with substantial reductions in cervical cancer incidence and mortality, even among previously screened women. It may be that after consideration of the reduced incidence of (and reduced mortality from) cervical cancer that may result from screening older women, the harms and economic costs of screening will be judged to outweigh its benefits. However, it is essential to consider the now-documented benefits of cervical screening when formulating screening guidelines for older women, and recommendations that do not do so will lack an evidence base.

    Colorectal cancer (CRC) ranks third among the most commonly diagnosed cancers worldwide, with wide geographical variation in incidence and mortality across the world. Despite proof that screening can decrease CRC incidence and mortality, CRC screening is only offered to a small proportion of the target population worldwide. Throughout the world there are widespread differences in CRC screening implementation status and strategy. Differences can be attributed to geographical variation in CRC incidence, economic resources, healthcare structure and infrastructure to support screening such as the ability to identify the target population at risk and cancer registry availability. This review highlights issues to consider when implementing a CRC screening programme and gives a worldwide overview of CRC burden and the current status of screening programmes, with focus on international differences.

    To analyse computed tomography (CT) findings of interval and post-screen carcinomas in lung cancer screening. Consecutive interval and post-screen carcinomas from the Dutch-Belgium lung cancer screening trial were included. The prior screening and the diagnostic chest CT were reviewed by two experienced radiologists in consensus with knowledge of the tumour location on the diagnostic CT. Sixty-one participants (53 men) were diagnosed with an interval or post-screen carcinoma. Twenty-two (36 %) were in retrospect visible on the prior screening CT. Detection error occurred in 20 cancers and interpretation error in two cancers. Errors involved intrabronchial tumour (n = 5), bulla with wall thickening (n = 5), lymphadenopathy (n = 3), pleural effusion (n = 1) and intraparenchymal solid nodules (n = 8). These were missed because of a broad pleural attachment (n = 4), extensive reticulation surrounding a nodule (n = 1) and extensive scarring (n = 1). No definite explanation other than human error was found in two cases. None of the interval or post-screen carcinomas involved a subsolid nodule. Interval or post-screen carcinomas that were visible in retrospect were mostly due to detection errors of solid nodules, bulla wall thickening or endobronchial lesions. Interval or post-screen carcinomas without explanation other than human errors are rare. (orig.)

    AIM: To discuss the efficacy of endoscopic mass screening for gastric cancer. METHODS: The data used in this study were the results of mass screening programs for gastric cancer in Niigata City from 2002 to 2004. The number of participants was 35089 in 2002, 34557 in 2003 and 36600 in 2004. The finding ratio referred to the final diagnosis of gastric cancer after a double check of endoscopic files and histological findings. The costs of identifying one case of gastric cancer were calculated based on the total expense for each screening program and additional close examinations. RESULTS: From the analysis of individual screening program with endoscopy, individual screening program with X-ray (ISX) and mass screening program with photofluorography (MSP) in reference to the finding ratio of gastric cancer, endoscopic examination was the best for detecting early gastric cancer, the finding ratio was 0.87% in 2004, approximately 2.7 and 4.6 times higher than those of the ISX and MSP groups. In addition, this novel method was the cheapest means regarding the cost of identifying one case of gastric cancer, which was estimated to be 1 608000 Japanese yen in 2004. CONCLUSION: Endoscopic mass screening is a promising method and can be effectively applied if a sufficient number of skilled endoscopists become available to staff the system and if city offices support it.

    Full Text Available Abstract Background Breast cancer screening in Denmark is organised by the health services in the five regions. Although general practitioners (GPs are not directly involved in the screening process, they are often the first point of contact to the health care system and thus play an important advisory role. No previous studies, in a health care setting like the Danish system, have investigated the association between GPs’ attitudes towards breast cancer screening and women’s participation in the screening programme. Methods Data on women’s screening participation was obtained from the regional screening authorities. Data on GPs’ attitudes towards breast cancer screening was taken from a previous survey among GPs in the Central Denmark Region. This study included women aged 50-69 years who were registered with a singlehanded GP who had participated in the survey. Results The survey involved 67 singlehanded GPs with a total of 13,288 women on their lists. Five GPs (7% had a negative attitude towards breast cancer screening. Among registered women, 81% participated in the first screening round. Multivariate analyses revealed that women registered with a GP with a negative attitude towards breast cancer screening were 17% (95% CI: 2-34% more likely to be non-participants compared with women registered with a GP with a positive attitude towards breast cancer screening. Conclusion The GPs' attitudes may influence the participation rate even in a system where GPs are not directly involved in the screening process. However, further studies are needed to investigate this association.

    The primary objective of the study was to identify early hematologic changes predictive for radiotherapy (RT)-associated genitourinary and gastrointestinal toxicity. In a group of 91 prostate cancer patients presenting for primary (n = 51) or postoperative (n = 40) curative RT, blood samples (blood count, acute phase proteins, and cytokines) were analyzed before (T1), three times during (T2-T4), and 6-8 weeks after (T5) radiotherapy. Before RT (baseline), on the last day (acute toxicity), a median of 2 months and 16 months (late toxicity) after RT, patients responded to a validated questionnaire (Expanded Prostate Cancer Index Composite). Acute score changes > 20 points and late changes > 10 points were considered clinically relevant. Radiotherapy resulted in significant changes of hematologic parameters, with the largest effect on lymphocytes (mean decrease of 31-45 %) and significant dependence on target volume. C-reactive protein (CRP) elevation > 5 mg/l and hemoglobin level decrease ≥ 5 G/1 at T2 were found to be independently predictive for acute urinary toxicity (p < 0.01, respectively). CRP elevation was predominantly detected in primary prostate RT (p = 0.02). Early lymphocyte level elevation ≥ 0.3G/l at T2 was protective against late urinary and bowel toxicity (p = 0.02, respectively). Other significant predictive factors for late bowel toxicity were decreasing hemoglobin levels (cut-off ≥ 5 G/l) at T2 (p = 0.04); changes of TNF-α (tumor necrosis factor; p = 0.03) and ferritin levels (p = 0.02) at T5. All patients with late bowel toxicity had interleukin (IL)-6 levels < 1.5 ng/l at T2 (63 % without; p = 0.01). Early hematologic changes during prostate cancer radiotherapy are predictive for late urinary and bowel toxicity. (orig.)

    Highlights: • We found variation in early performance measures across screening centres. • Radiologists’ performance may play a key role in the variability. • Potential to improve the effectiveness of breast cancer screening programs. • Continuous surveillance of screening centres and radiologists is essential. - Abstract: Background: Recall for assessment in mammographic screening entails an inevitable number of false-positive screening results. This study aimed to investigate the variation in the cumulative risk of a false positive screening result and the positive predictive value across the screening centres in the Norwegian Breast Cancer Screening Program. Methods: We studied 618,636 women aged 50–69 years who underwent 2,090,575 screening exams (1996–2010. Recall rate, positive predictive value, rate of screen-detected cancer, and the cumulative risk of a false positive screening result, without and with invasive procedures across the screening centres were calculated. Generalized linear models were used to estimate the probability of a false positive screening result and to compute the cumulative false-positive risk for up to ten biennial screening examinations. Results: The cumulative risk of a false-positive screening exam varied from 10.7% (95% CI: 9.4–12.0%) to 41.5% (95% CI: 34.1–48.9%) across screening centres, with a highest to lowest ratio of 3.9 (95% CI: 3.7–4.0). The highest to lowest ratio for the cumulative risk of undergoing an invasive procedure with a benign outcome was 4.3 (95% CI: 4.0–4.6). The positive predictive value of recall varied between 12.0% (95% CI: 11.0–12.9%) and 19.9% (95% CI: 18.3–21.5%), with a highest to lowest ratio of 1.7 (95% CI: 1.5–1.9).

    There are one-step and two-steps programs for colorectal cancer screening. The aim of all screening examinations is to detect early stage of the disease in asymptomatic patient. The aim of this article is actual review of current screening modalities such as fecal occult blood test, flexible sigmoideoscopy, colonoscopy, CT colonography, capsule endoscopy, blood-based tests and stool DNA tests. Colonoscopy still remains the gold standard for detection of colorectal neoplasias. In majority of countries worldwide programs for colorectal cancer screening are based on immunochemical fecal occult blood test followed by colonoscopy when positive.

    Asian women, including Korean, have a relatively higher incidence of dense breast tissue, compared with western women. Dense breast tissue has a lower sensitivity for the detection of breast cancer and a higher relative risk for breast cancer, compared with fatty breast tissue. Thus, there were limitations in the mammographic screening for women with dense breast tissue, and many studies for the supplemental screening methods. This review included appropriate screening methods for Korean women with dense breasts. We also reviewed the application and limitation of supplemental screening methods, including breast ultrasound, digital breast tomosynthesis, and breast magnetic resonance imaging; and furthermore investigated the guidelines, as well as the study results.

    Objective: The aim of this study was to use lung cancer targeting binding polypeptide ZS-9 to screen cDNA library of human lung cancer and obtain ZS-9 specific ligand to confirm tumor marker of non small-cell lung cancer. Methods: Artificially synthesize biotin labeled peptide ZS-9, anchored ZS-9 in the enzyme label plate coupled by avidin, used ZS-9 as probe to screen cDNA library of human lung cancer, after screening, obtained bacteriophage clone specifically binding with anchored polypeptide ZS-9. Extracted plasmid of bacteriophage and performed sequencing after amplified by PCR. Results: It was demonstrated by bioinformatic analysis on the sequence of ligand binded by lung cancer specific peptide ZS-9 that the ligand was the cytoskeletal protein periplakin on the surface of lung cancer cells, suggesting that periplakin might be a new marker for non-small-cell lung cancer in lung cancer. Conclusion: Use specific lung cancer binding peptide to screen new tumor marker periplakin in lung cancer and further studies on its biologic functions in genesis and development of lung cancer are still needed.

    Dynamic thermal imaging (DTI) with infrared cameras is a non-invasive technique with the ability to detect the most common types of skin cancer. We discuss and propose a standardized analysis method for DTI of actual patient data, which achieves high levels of sensitivity and specificity by judiciously selecting pixels with the same initial temperature. This process compensates the intrinsic limitations of the cooling unit and is the key enabling tool in the DTI data analysis. We have extensively tested the methodology on human subjects using thermal infrared image sequences from a pilot study conducted jointly with the University of New Mexico Dermatology Clinic in Albuquerque, New Mexico (ClinicalTrials ID number NCT02154451). All individuals were adult subjects who were scheduled for biopsy or adult volunteers with clinically diagnosed benign condition. The sample size was 102 subjects for the present study. Statistically significant results were obtained that allowed us to distinguish between benign and malignant skin conditions. The sensitivity and specificity was 95% (with a 95% confidence interval of [87.8% 100.0%]) and 83% (with a 95% confidence interval of [73.4% 92.5%]), respectively, and with an area under the curve of 95%. Our results lead us to conclude that the DTI approach in conjunction with the judicious selection of pixels has the potential to provide a fast, accurate, non-contact, and non-invasive way to screen for common types of skin cancer. As such, it has the potential to significantly reduce the number of biopsies performed on suspicious lesions.

  4. Study of mammography in mass screening for breast cancer

    International Nuclear Information System (INIS)

    In order to examine the rate of correct diagnosis by mammography at initial mass screening for breast cancer, we carried out a retrospective study of mammography findings in 267 cases of breast cancer detected at Asahikawa Cancer Screening Center. The screening was performed by physical examination, and in cases where disease was suspected, mammography, ultrasonography, and needle biopsy were done. Mammographically, 172 cases (64.4%) were cancer-positive, 58 cases (21.7%) were suspicious for cancer, and 37 cases (13.9%) were cancer-negative. Patients below 50 years of age and those with tumors of small diameter (<20 mm) showed a significantly lower rate of cancer positivity than patients aged 50 years or more and those with tumors 20 mm or more in diameter. Mammographic abnormalities were not specific, since these changes were also found in normal subjects and patients with benign diseases. Therefore, we concluded that mammography without physical examination at initial mass screening has a high risk of missing breast cancer. Mass screening for breast cancer should be performed by physical examination involving inspection and palpation at the first instance. If any suspicious findings are obtained, mammography, ultrasonography, and needle biopsy should be done. (author)

  5. Development of a Federally Funded Demonstration Colorectal Cancer Screening Program

    Full Text Available Colorectal cancer is the second leading cause of cancer-related mortality among U.S. adults. In 2004, treatment costs for colorectal cancer were $8.4 billion.There is substantial evidence that colorectal cancer incidence and mortality are reduced with regular screening. The natural history of this disease is also well described: most colorectal cancers develop slowly from preexisting polyps. This slow development provides an opportunity to intervene with screening tests, which can either prevent colorectal cancer through the removal of polyps or detect it at an early stage. However, much less is known about how best to implement an effective colorectal cancer screening program. Screening rates are low, and uninsured persons, low-income persons, and persons who have not visited a physician within a year are least likely to be screened.Although the Centers for Disease Control and Prevention (CDC has 15 years of experience supporting the National Breast and Cervical Cancer Early Detection Program for the underserved population, a similar national program for colorectal cancer is not in place. To explore the feasibility of implementing a national program for the underserved U.S. population and to learn which settings and which program models are most viable and cost-effective, CDC began a 3-year colorectal cancer screening demonstration program in 2005.This article describes briefly this demonstration program and the process CDC used to design it and to select program sites. The multiple-methods evaluation now under way to assess the program’s feasibility and describe key outcomes is also detailed. Evaluation results will be used to inform future activities related to organized screening for colorectal cancer.

    Androgen deprivation therapy (ADT) is the mainstay treatment for advanced prostate cancer. By lowering androgen levels, ADT inhibits the progression of prostate cancer, but it may also affect gut autoimmunity. We investigated the association between ADT and the incidence of inflammatory bowel disease using a cohort of 31,842 men newly diagnosed with prostate cancer between 1988 and 2014, identified in the United Kingdom Clinical Practice Research Datalink. Exposure to ADT was treated as a time-varying variable and lagged by 1 year to account for diagnostic delays, with nonuse as the reference category. During 133,018 person-years of follow-up, 48 men were newly diagnosed with ulcerative colitis (incidence rate (IR) = 36/100,000 person-years (PY)) and 12 were diagnosed with Crohn's disease (IR = 9/100,000 PY). In Cox proportional hazards models, ADT was associated with a decreased risk of ulcerative colitis (IR = 24/100,000 PY vs. IR = 50/100,000 PY; hazard ratio = 0.52, 95% confidence interval: 0.28, 0.99) and a nonsignificant decreased risk of Crohn's disease (hazard ratio = 0.38, 95% confidence interval: 0.11, 1.37). These findings indicate that the use of ADT may be associated with intestinal autoimmunity. Further research is warranted to replicate these findings and assess their clinical significance.

  7. Screening for breast cancer in a high-risk series

    International Nuclear Information System (INIS)

    A unique cohort of women at increased risk of breast cancer because of prior X-ray treatment of acute mastitis and their selected high-risk siblings were offered periodic breast cancer screening including physical examination of the breasts, mammography, and thermography. Twelve breast cancers were detected when fewer than four would have been expected based on age-specific breast cancer detection rates from the National Cancer Institute/American Cancer Society Breast Cancer Demonstration Detection Projects. Mammography was positive in all cases but physical examination was positive in only three cases. Thermography was an unreliable indicator of disease. Given the concern over radiation-induced risk, use of low-dose technique and of criteria for participation that select women at high risk of breast cancer will maximize the benefit/risk ratio for mammography screening

    Full Text Available Background: The primary objective was to examine and compare the breast cancer screening adherence rates between black (African American and Afro-Caribbean and Hispanic (foreign born Hispanic and US-born Hispanic subpopulations. Methods: Study data was collected in community settings in New York City between the years of 2011-2012. Participants (N=592 were black and Hispanic individuals who attended a breast cancer screening community outreach program. Breast cancer screening rates as well as demographic data were collected. Results: Results revealed that Afro-Caribbean and foreign-born Hispanics are at a greater risk for non-adherence in breast cancer screening compared with African Americans and US-born Hispanics. Conclusions: The majority of breast screening research and community outreach programs categorize people into broad racial and ethnic groups (e.g., black and Hispanic. The results revealed significant variability within these broader racial/ethnic categories with regard to breast cancer screening. Community outreach programs and future research efforts should target the subpopulations that are at particular risk for breast cancer screening non-adherence.

    Pancreatic cancer is difficult to diagnose at an early stage and is associated with a very poor survival. Ten percent of pancreatic cancers result from genetic susceptibility and/or familial aggregation. Individuals from families with multiple affected first-degree relatives and those with a known cancer-causing genetic mutation have been shown to be at much higher risk of developing pancreatic cancer. Recent efforts have focused on detecting disease at an earlier stage to improve survival in these high-risk groups. This article reviews high-risk groups, screening methods, and current screening programs and their results.

    Cancer screening is widely practiced and participation is promoted by various social, technical, and commercial drivers, but there are growing concerns about the emerging harms, risks, and costs of cancer screening. Deliberative democracy methods engage citizens in dialogue on substantial and complex problems: especially when evidence and values are important and people need time to understand and consider the relevant issues. Information derived from such deliberations can provide important guidance to cancer screening policies: citizens' values are made explicit, revealing what really matters to people and why. Policy makers can see what informed, rather than uninformed, citizens would decide on the provision of services and information on cancer screening. Caveats can be elicited to guide changes to existing policies and practices. Policies that take account of citizens' opinions through a deliberative democracy process can be considered more legitimate, justifiable, and feasible than those that don't.

    INTRODUCTION: A reason for not recommending subtotal hysterectomy is the risk of cervical pathology. We aimed to evaluate cervical cancer screening and to describe cervical pathology after subtotal and total hysterectomy for benign indications. METHODS: Data regarding adherence to screening.......7% were not screened. We found a minimum of one abnormal test in 28 (10.8%) after subtotal hysterectomy and one after total hysterectomy. No cervical cancers were found. CONCLUSIONS: Adherence to cervical cancer screening after subtotal hysterectomy in a Danish population is suboptimal and some patients...... have unnecessary tests performed after total hysterectomy. Clarification of the use of cervical/vaginal smears after hysterectomy is needed to identify women at risk of cervical dysplasia or cancer.

    2015-01-01

    Full Text Available Introduction: An increased number of screen failure patients in a clinical trial increases time and cost required for the recruitment. Assessment of reasons for screen failure can help reduce screen failure rates and improve recruitment. Materials and Methods: We collected retrospective data of human epidermal growth factor receptor (HER2 positive Indian breast cancer patients, who failed screening for phase 3 clinical trials and ascertained their reasons for screen failure from screening logs. Statistical comparison was done to ascertain if there are any differences between private and public sites. Results: Of 727 patients screened at 14 sites, 408 (56.1% failed screening. The data on the specific reasons for screen failures was not available at one of the public sites (38 screen failures out of 83 screened patients. Hence, after excluding that site, further analysis is based on 644 patients, of which 370 failed screening. Of these, 296 (80% screen failure patients did not meet selection criteria. The majority -266 were HER2 negative. Among logistical issues, 39 patients had inadequate breast tissue sample. Sixteen patients withdrew their consent at private sites as compared to six at public sites. The difference between private and public sites for the above three reasons was statistically significant. Conclusion: Use of prescreening logs to reduce the number of patients not meeting selection criteria and protocol logistics, and patient counseling to reduce consent withdrawals could be used to reduce screen failure rate.

    AIM: To perform sequencing analysis in patients with very early-onset inflammatory bowel disease (VEO-IBD) to determine the genetic basis for VEO-IBD in Chinese pediatric patients. METHODS: A total of 13 Chinese pediatric patients with VEO-IBD were diagnosed from May 2012 and August 2014. The relevant clinical characteristics of these patients were analyzed. Then DNA in the peripheral blood from patients was extracted. Next generation sequencing (NGS) based on an Illumina-Miseq platform was used to analyze the exons in the coding regions of 10 candidate genes: IL-10, IL-10RA, IL-10RB, NOD2, FUT2, IL23R, GPR35, GPR65, TNFSF15, and ADAM30. The Sanger sequencing was used to verify the variations detected in NGS. RESULTS: Out of the 13 pediatric patients, ten were diagnosed with Crohn’s disease, and three diagnosed with ulcerative colitis. Mutations in IL-10RA and IL-10RB were detected in five patients. There were four patients who had single nucleotide polymorphisms associated with IBD. Two patients had IL-10RA and FUT2 polymorphisms, and two patients had IL-10RB and FUT2 polymorphisms. Gene variations were not found in the rest four patients. Children with mutations had lower percentile body weight (1.0% vs 27.5%, P = 0.002) and hemoglobin (87.4 g/L vs 108.5 g/L, P = 0.040) when compared with children without mutations. Although the age of onset was earlier, height was shorter, and the response to treatment was poorer in the mutation group, there was no significant difference in these factors between groups. CONCLUSION: IL-10RA and IL-10RB mutations are common in Chinese children with VEO-IBD. Patients with mutations have an earlier disease onset, lower body weight and hemoglobin, and poorer prognosis.

    Colorectal cancer is currently the second most common cancer among Korean males and the fourth most common among females. Since the majority of colorectal cancer case present following the prolonged transformation of adenomas into carcinomas, early detection and removal of colorectal adenomas are vital methods in its prevention. Considering the increasing incidence of colorectal cancer and polyps in Korea, it is very important to establish national guidelines for colorectal cancer screening and polyp detection. The proposed guidelines have been developed by the Korean Multi-Society Task Force using evidence-based methods. Systematic reviews and meta-analyses have been used to form the statements contained in the guidelines. This paper discusses the epidemiology of colorectal cancers and adenomas in Korea as well as optimal methods for screening of colorectal cancer and detection of adenomas including fecal occult blood tests, radiologic tests, and endoscopic examinations.

    2016-09-01

    The US National Lung Screening Trial showed that individuals randomly assigned to screening with low-dose CT scans had 20% lower lung cancer mortality than did those screened with conventional chest radiography. On the basis of a review of the literature and a modelling study, the US Preventive Services Task Force recommends annual screening for lung cancer for individuals aged 55-80 years who have a 30 pack-year smoking history and either currently smoke or quit smoking within the past 15 years. However, the balance between benefits and harms of lung cancer screening is still greatly debated. The large number of false-positive results and the potential for overdiagnosis are causes for concern. Some investigators suggest the ratio between benefits and harms could be improved through various means. Nevertheless, many questions remain with regard to the implementation of lung cancer screening. This paper highlights the latest developments in CT lung cancer screening and provides an overview of the main unanswered questions. PMID:27599248

  2. Environmental scan of anal cancer screening practices: worldwide survey results

    International Nuclear Information System (INIS)

    Anal squamous cell carcinoma is rare in the general population but certain populations, such as persons with HIV, are at increased risk. High-risk populations can be screened for anal cancer using strategies similar to those used for cervical cancer. However, little is known about the use of such screening practices across jurisdictions. Data were collected using an online survey. Health care professionals currently providing anal cancer screening services were invited to complete the survey via email and/or fax. Information was collected on populations screened, services and treatments offered, and personnel. Over 300 invitations were sent; 82 providers from 80 clinics around the world completed the survey. Fourteen clinics have each examined more than 1000 patients. Over a third of clinics do not restrict access to screening; in the rest, eligibility is most commonly based on HIV status and abnormal anal cytology results. Fifty-three percent of clinics require abnormal anal cytology prior to performing high-resolution anoscopy (HRA) in asymptomatic patients. Almost all clinics offer both anal cytology and HRA. Internal high-grade anal intraepithelial neoplasia (AIN) is most often treated with infrared coagulation (61%), whereas external high-grade AIN is most commonly treated with imiquimod (49%). Most procedures are performed by physicians, followed by nurse practitioners. Our study is the first description of global anal cancer screening practices. Our findings may be used to inform practice and health policy in jurisdictions considering anal cancer screening

    Hematopoietic stem cell transplant (HCT) recipients have a substantial risk of developing secondary solid cancers, particularly beyond 5 years after HCT and without reaching a plateau overtime. A working group was established through the Center for International Blood and Marrow Transplant Research and the European Group for Blood and Marrow Transplantation with the goal to facilitate implementation of cancer screening appropriate to HCT recipients. The working group reviewed guidelines and methods for cancer screening applicable to the general population and reviewed the incidence and risk factors for secondary cancers after HCT. A consensus approach was used to establish recommendations for individual secondary cancers. The most common sites include oral cavity, skin, breast and thyroid. Risks of cancers are increased after HCT compared with the general population in skin, thyroid, oral cavity, esophagus, liver, nervous system, bone and connective tissues. Myeloablative TBI, young age at HCT, chronic GVHD and prolonged immunosuppressive treatment beyond 24 months were well-documented risk factors for many types of secondary cancers. All HCT recipients should be advised of the risks of secondary cancers annually and encouraged to undergo recommended screening based on their predisposition. Here we propose guidelines to help clinicians in providing screening and preventive care for secondary cancers among HCT recipients. PMID:25822223

    Human immunodeficiency virus (HIV)-infected women are at increased risk of invasive cervical cancer; however, screening rates remain low. The objectives of this study were to analyze a quality improvement intervention to increase cervical cancer screening rates in an urban academic HIV clinic and to identify factors associated with inadequate screening. Barriers to screening were identified by a multidisciplinary quality improvement committee at the Washington University Infectious Diseases clinic. Several strategies were developed to address these barriers. The years pre- and post-implementation were analyzed to examine the clinical impact of the intervention. A total of 422 women were seen in both the pre-implementation and post-implementation periods. In the pre-implementation period, 222 women (53%) underwent cervical cancer screening in the form of Papanicolaou (Pap) testing. In the post-implementation period, 318 women (75.3%) underwent cervical cancer screening (p screening included fewer visits attended (pre: 4.2 ± 1.5; post: 3.4 ± 1.4; p screening rates in an urban academic HIV clinic.

  14. Screening in breast cancer: a view from the front line

    International Nuclear Information System (INIS)

    Mammography screning presents the only real breakthrough in breast cancer in this century. Twenty-five percent of all cancer in women is breast cancer. About 50 percent of these women die from their disease. It has not been possible to reduce breast cancer mortality more than marginally by any mode of treatment. Single view mammography screening can do so, however, at the rate of 30 to 40 percent. Screening has many detractors, especially in the treatment camp. These detractors do not always act in the patients' best interests. Considering the vast resources used up until now in trying to improve on breast cancer treatment, and to little avail, it is time to divert some of these efforts to set up screening programmes wherever possible. Well handled, these are able to reduce suffering and health care costs and save lines

    2015-01-01

    Lung cancer has remained the leading cause of death worldwide among all cancers. The dismal 5-year survival rate of 16% is in part due to the lack of symptoms during early stages and lack of an effective screening test until recently. Chest X-ray and sputum cytology were studied extensively as potential screening tests for lung cancer and were conclusively proven to be of no value. Subsequently, a number of studies compared computed tomography (CT) with the chest X-ray. These studies did identify lung cancer in earlier stages. However, they were not designed to prove a reduction in mortality. Later trials have focused on low-dose CT (LDCT) as a screening tool. The largest US trial – the National Lung Screening Trial (NLST) – enrolled approximately 54,000 patients and revealed a 20% reduction in mortality. While a role for LDCT in lung cancer screening has been established, the issues of high false positive rates, radiation risk, and cost effectiveness still need to be addressed. The guidelines of the international organizations that now include LDCT in lung cancer screening are reviewed. Other methods that may improve earlier detection such as positron emission tomography, autofluorescence bronchoscopy, and molecular biomarkers are also discussed. PMID:26528348

  17. Analysis of previous screening examinations for patients with breast cancer

    International Nuclear Information System (INIS)

    We wanted to improve the quality of subsequent screening by reviewing the previous screening of breast cancer patients. Twenty-four breast cancer patients who underwent previous screening were enrolled. All 24 took mammograms and 15 patients also took sonograms. We reviewed the screening retrospectively according to the BI-RADS criteria and we categorized the results into false negative, true negative, true positive and occult cancers. We also categorized the causes of false negative cancers into misperception, misinterpretation and technical factors and then we analyzed the attributing factors. Review of the previous screening revealed 66.7% (16/24) false negative, 25.0% (6/24) true negative, and 8.3% (2/24) true positive cancers. False negative cancers were caused by the mammogram in 56.3% (9/16) and by the sonogram in 43.7% (7/16). For the false negative cases, all of misperception were related with mammograms and this was attributed to dense breast, a lesion located at the edge of glandular tissue or the image, and findings seen on one view only. Almost all misinterpretations were related with sonograms and attributed to loose application of the final assessment. To improve the quality of breast screening, it is essential to overcome the main causes of false negative examinations, including misperception and misinterpretation. We need systematic education and strict application of final assessment categories of BI-RADS. For effective communication among physicians, it is also necessary to properly educate them about BI-RADS

  18. Imaging screening of breast cancer: primary results in 5307 cases

    International Nuclear Information System (INIS)

    Objective: To discuss the values of three screening methods for the detection of early breast cancer, and to analyze the features of the screening cancer. Methods: The first screening of breast cancer were performed in 5307 women who aged from 20 to 76 years with median age of 49 years. The three screening methods included physical examination with ultrasound and mammography, physical examination with mammography and mammography only. The rate of recall, biopsy, cancer detection of three methods were analyzed and the mammographic findings were reviewed. Chi-square test or Fisher's exact test were used for the statistics. Results: The recall rates were 4.90% (49/1001), 6.90% (166/2407) and 4. 48% (85/1899) in three methods respectively, the biopsy rates were 1.60% (16/1001), 1.04% (25/2407) and 0.63% (12/1899), the cancer detection rates were 0.50% (5/1001), 0.17% (4/2407) and 0 (0/1899). There were statistical differences among the three groups (χ2=12.99,6.264,8.764, P<0.05). Physical examination with ultrasound and mammography had the highest cancer detection rate, ten breast cancers were detected and 8 were early stage breast cancer. Of seven cancers detected by mammography, only two were found by ultrasound. A cluster of calcifications were found in 2 cases, linear calcifications in 2 cases. One case presented as a asymmetric density, one as a asymmetric density with calcifications, one as multiple nodules with a cluster of calcifications. Two breast cancers presented as asymmetric density were missed on mammography and diagnosed correctly after retrospective review. Conclusion: Physical examination with ultrasound and mammography is the best method for breast cancer screening. The breast cancer can be detected by mammography earlier than other methods.

    Purpose: We have previously shown that intensity-modulated radiotherapy (IMRT) can reduce dose to small bowel, bladder, and bone marrow compared with three-field conventional radiotherapy (CRT) technique in the treatment of rectal cancer. The purpose of this study was to review our experience using IMRT to treat rectal cancer and report patient clinical outcomes. Methods and Materials: A retrospective review was conducted of patients with rectal cancer who were treated at Mayo Clinic Arizona with pelvic radiotherapy (RT). Data regarding patient and tumor characteristics, treatment, acute toxicity according to the Common Terminology Criteria for Adverse Events v 3.0, tumor response, and perioperative morbidity were collected. Results: From 2004 to August 2009, 92 consecutive patients were treated. Sixty-one (66%) patients were treated with CRT, and 31 (34%) patients were treated with IMRT. All but 2 patients received concurrent chemotherapy. There was no significant difference in median dose (50.4 Gy, CRT; 50 Gy, IMRT), preoperative vs. postoperative treatment, type of concurrent chemotherapy, or history of previous pelvic RT between the CRT and IMRT patient groups. Patients who received IMRT had significantly less gastrointestinal (GI) toxicity. Sixty-two percent of patients undergoing CRT experienced {>=}Grade 2 acute GI side effects, compared with 32% among IMRT patients (p = 0.006). The reduction in overall GI toxicity was attributable to fewer symptoms from the lower GI tract. Among CRT patients, {>=}Grade 2 diarrhea and enteritis was experienced among 48% and 30% of patients, respectively, compared with 23% (p = 0.02) and 10% (p = 0.015) among IMRT patients. There was no significant difference in hematologic or genitourinary acute toxicity between groups. In addition, pathologic complete response rates and postoperative morbidity between treatment groups did not differ significantly. Conclusions: In the management of rectal cancer, IMRT is associated with a

    The inflammatory bowel diseases (IBD),Crohn's disease (CD) and ulcerative colitis (UC),may be complicated by colorectal cancer (CRC).In a recent populationbased cohort study of 47 347 Danish patients with IBD by Tine Jess and colleagues 268 patients with UC and 70 patients with CD developed CRC during 30 years of observation.The overall risk of CRC among patients with UC and CD was comparable with that of the general population.However,patients diagnosed with UC during childhood or as adolescents,patients with long duration of disease and those with concomitant primary sclerosing cholangitis were at increased risk.In this commentary,we discuss the mechanisms underlying carcinogenesis in IBD and current investigations of genetic susceptibility in IBD patients.Further advances will depend on the cooperative work by epidemiologist and molecular geneticists in order to identify genetic polymorphisms involved in IBD-associated CRC.The ultimate goal is to incorporate genotypes and clinical parameters into a predictive model that will refine the prediction of risk for CRC in colonic IBD.The challenge will be to translate these new findings into clinical practice and to determine appropriate preventive strategies in order to avoid CRC in IBD patients.The achieved knowledge may also be relevant for other inflammation-associated cancers.

The initial step involved use of confirmatory factor analysis, that included the following variables: access to and satisfaction with health care, and enabling and predisposing cultural and health beliefs. Structural equation model analyses were conducted on factors related to cervical cancer screening.Results: Age, marital status, employment, household income, and having health insurance, but not educational level, were significantly related to cervical screening status. Predisposing and enabling factors were positively associated with cervical cancer screening. The cultural factor was significantly related to the enabling factor or the satisfaction with health care factor.Conclusion: This model highlights the significance of sociocultural factors in relation to cervical cancer screening. These factors were significant, with cultural, predisposing, enabling, and health belief factors and access to and satisfaction with health care reinforcing the need to assist Chinese American women with poor English fluency in translation and awareness of the importance of cervical

    Cytology-based nation-wide cervical screening has led to a substantial reduction of the incidence of cervical cancer in western countries. However, the sensitivity of cytology for the detection of high-grade precursor lesions or cervical cancer is limited; therefore, repeated testing is necessary to achieve program effectiveness. Additionally, adenocarcinomas and its precursors are often missed by cytology. Consequently, there is a need for a better screening test. The insight that infection with high-risk human papillomavirus (hrHPV) is the causal agent of cervical cancer and its precursors has led to the development of molecular tests for the detection of hrHPV. Strong evidence now supports the use of hrHPV testing in the prevention of cervical cancer. In this review, we will discuss the arguments in favor of, and concerns on aspects of implementation of hrHPV testing in primary cervical cancer screening, such as the age to start hrHPV-based screening, ways to increase screening attendance, requirements for candidate hrHPV tests to be used, and triage algorithms for screen-positive women.

    Full Text Available Abstract Background Despite the existence of different screening methods, the response to cancer screening is poor among Malaysians. The current study aims to examine cancer patients’ perceptions of cancer screening and early diagnosis. Methods A qualitative methodology was used to collect in-depth information from cancer patients. After obtaining institutional ethical approval, patients with different types and stages of cancer from the three major ethnic groups (Malay, Chinese and Indian were approached. Twenty semi-structured interviews were conducted. All interviews were audiotaped, transcribed verbatim, and translated into English for thematic content analysis. Results Thematic content analysis yielded four major themes: awareness of cancer screening, perceived benefits of cancer screening, perceived barriers to cancer screening, and cues to action. The majority of respondents had never heard of cancer screening before their diagnosis. Some participants reported hearing about mammogram and Pap smear tests but did not undergo screening due to a lack of belief in personal susceptibility. Those who had negative results from screening prior to diagnosis perceived such tests as untrustworthy. Lack of knowledge and financial constraints were reported as barriers to cancer screening. Finally, numerous suggestions were given to improve screening behaviour among healthy individuals, including the role of mass media in disseminating the message ‘prevention is better than cure’. Conclusions Patients’ narratives revealed some significant issues that were in line with the Health Belief Model which could explain negative health behaviour. The description of the personal experiences of people with cancer could provide many cues to action for those who have never encountered this potentially deadly disease, if incorporated into health promotion activities.

  8. Transillumination in breast cancer detection: screening failures and potential

    International Nuclear Information System (INIS)

    This prospective study of 1265 women referred to a multimodality breast diagnostic center compares the sensitivity for breast cancer detection of state-of-the-art transillumination light scanning and film-screen mammography. Of 33 biopsy-proven cancers, transillumination light scanning detected 58%, while mammography detected 97% of the cancers. Light scanning did detect 55% of the nonpalpable breast cancers, and 30% of those tumors smaller than 1 cm. Detection of breast cancer by light scanning was affected by breast size, but not architecture, and was directly related to tumor size. Although transillumination light scanning can detect some small curable breast cancers (smaller than 1 cm), it does not do so at a sensitivity adequate for screening

    The role of lifestyle risk factors in prostate cancer risk remains elusive despite a large number of epidemiologic studies. In a pooled analysis of data from South and East Asian countries published in this issue, Fowke et al. (Am J Epidemiol. 2015;182(5):381-389) found no evidence for an association between prostate cancer mortality and obesity, alcohol, or smoking. Prostate cancer screening is very uncommon in these countries, and previous evidence for associations with lifestyle factors comes primarily from studies carried out in North America, where screening is very common. Fowke et al. concluded that screening biases are likely to explain the differences in study results. In this commentary, we discuss the potential influence of population-based cancer screening programs in estimates of association from epidemiologic studies. This highlights the importance of carefully considering the impact of screening in the analysis and interpretation of results, in order to advance our understanding of the etiology of cancers that can be detected by screening.

    The Cochrane analysis exploring the risk/benefit ratio of breast cancer screening resulted in a controversy worldwide spread by the mass media. Our survey sought to assess the impact of this controversy in terms of breast cancer screening awareness and attendance. A nationwide observational study, recorded in the EDIFICE iterative surveys, with a representative sample of 451 women aged 40-75 years, living in France, was carried out in the 3 months after the start of the controversy in January 2013. Of the 405 women with no personal history of cancer, 69 (17%) declared having heard of the controversy (aware group). Women remembering the controversy were more likely to belong to higher socioprofessional categories and to have a higher level of education. The most frequently remembered issues were overdiagnosis (38%), unreliability (16%) and radiation risk (9%). Compared with women who were unaware of the controversy, the aware group knew more about the limits of breast cancer screening (undiagnosed cancers, 20 vs. 7%, Pmass media debate (8.7 vs. 1.2%, P<0.05). Nevertheless, only 1% of the aware-group declared their intention to subsequently undergo screening less frequently. The low impact of the controversy on the behaviour of women with respect to screening suggests that it should not be seen as a threat to screening attendance rates, but more as an opportunity to improve awareness.

    2012-01-01

    The association between inflammatory bowel disease (IBD) and colorectal cancer (CRC) has been recognised since 1925 and still accounts for 10%-15% of deaths in IBD.IBD-associated CRC (IBD-CRC) affects patients at a younger age than sporadic CRC.The prognosis for sporadic CRC and IBD-CRC is similar,with a 5-year survival of approximately 50%.Identifying at risk patients and implementing appropriate surveillance for these patients is central to managing the CRC risk in IBD.The increased risk of colorectal cancer in association with IBD is thought to be due to genetic and acquired factors.The link between inflammation and cancer is well recognised but the molecular biology,immune pathobiology and genetics of IBD-CRC are areas of much ongoing research.This review examines the literature relating to IBD-CRC,focusing on the incidence of IBD-CRC and examining potential risk factors including age at diagnosis,gender,duration and extent of colitis,severity of inflammation,family history of sporadic CRC and co-existent primary sclerosing cholangitis (PSC).Confirmed risk factors for IBD-CRC are duration,severity and extent of colitis,the presence of co-existent PSC and a family history of CRC.There is insufficient evidence currently to support an increased frequency of surveillance for patients diagnosed with IBD at a younger age.Evidence-based guidelines advise surveillance colonoscopy for patients with colitis 8 to 10 years after diagnosis,with the interval for further surveillance guided by risk factors (extent of disease,family history of CRC,post-inflammatory polyps,concomitant PSC,personal history of colonic dysplasia,coIonic strictures).There is a move away from using random colonic biopsies towards targeted biopsies aimed at abnormal areas identified by newer colonoscopic techniques (narrow band imaging,chromoendoscopy,confocal microendoscopy).

    AIM: To investigate the phenotype of inflammatory bowel disease associated with primary sclerosing cholangitis (PSC-IBD).METHODS: Data from 75 PSC-]BD patients evaluated in our tertiary center between 1963 and 2006 were collected and compared to 150 IBD patients without PSC, matched for sex, birth date, IBD diagnosis date and initial disease location regarding ileal, different colonic segments, and rectum, respectively.RESULTS: While PSC-IBD patients received more 5-aminosalicylates (8.7 years/patient vs 2.9 years/patient, P<0.001), they required less immunosuppressors (24% vs 46% at 10 years; P<0.001) and less intestinal resection (10% vs 44% at 10 years, P<0.001). The 25-year cumulative rate of colectomy was 25.1% in PSC-IBD and 37.3% in controls (P=0.004). The 25-year cumulative rate of colorectal cancer was 23.4% in PSC-IBD vs 0% in controls (P=0.002). PSC was the only independent risk factor for the development of colorectal cancer (OR=10.8; 95%CI, 3.7-31.3). Overall survival rate without liver transplantation was reduced in PSC-IBD patients (67% vs 91% in controls at 25 years, P=0.001).CONCLUSION: This study confirms that patients with PSC-IBD have a particular disease phenotype independent of the initial disease location. Although their disease is less active and they use more 5-aminosalicylates, they present a higher risk of colorectal cancer.

Since the National Lung Screening Research Team (NLSRT (1 published the impressive results showing a 20% reduction in lung cancer mortality, the debate on when and if to initiate a national lung cancer screening program has been at the forefront of debate. The American Lung Association and American Cancer Society have issued statements that are not guidelines, but did offer insight on the price we pay for earlier lung cancer detection and reduction in mortality…which is the increased rates of false positives detected and increased rates of biopsies. The US Task Force on Lung Cancer Screening has yet to decide on a screening program and have yielded a statement that neither supports nor refutes the current level of evidence. Prior to the NLSRT study there were others that showed conflicting results on …

    Drug candidates often fail in preclinical and clinical testing because of reasons of efficacy and/or safety.It would be time- and cost-efficient to have screening models that reduce the rate of such false positive candidates that appear promising at first but fail later.In this regard,it would be particularly useful to have a rapid and inexpensive whole animal model that can pre-select hits from high-throughput screens but before testing in costly rodent assays.Drosophila melanogaster has emerged as a potential whole animal model for drug screening.Of particular interest have been drugs that must act in the context of multi-cellularity such as those for neurological disorders and cancer.A recent review provides a comprehensive summary of drug screening in Drosophila,but with an emphasis on neurodegenerative disorders.Here,we review Drosophila screens in the literature aimed at cancer therapeutics.

    Background Breast and colon cancer screening in rural community clinics is underused. Objective To evaluate the effectiveness and cost-effectiveness of alternative interventions designed to promote simultaneous screening for breast and colon cancer in community clinics. Methods A 3-arm, quasi-experimental evaluation was conducted during May 2008-August 2011 in 8 federally qualifed health clinics in predominately rural Louisiana. Baseline screening rates reported by the clinics was <10% for breast cancer (using mammography) and 1%-2% for colon cancer (using the fecal occult blood test [FOBT]). 744 women aged 50 years or older who were eligible for routine mammography and an FOBT were recruited. The combined screening efforts included: enhanced care; health literacy-informed education (education alone), or health literacy-informed education with nurse support (nurse support). Results Postintervention screening rates for completing both tests were 28.1% with enhanced care, 23.7% with education alone, and 38.7% with nurse support. After adjusting for age, race, and literacy, patients who received nurse support were 2.21 times more likely to complete both screenings than were those who received the education alone (95% confidence interval [CI], 1.12-4.38; P = .023). The incremental cost per additional woman completing both screenings was $3,987 for education with nurse support over education alone, and $5,987 over enhanced care. Limitations There were differences between the 3 arms in sociodemographic characteristics, literacy, and previous screening history. Not all variables that were significantly different between arms were adjusted for, therefore adjustments for key variables (age, race, literacy) were made in statistical analyses. Other limitations related generalizability of results. Conclusions Although joint breast and colon cancer screening rates were increased substantially over existing baseline rates in all 3 arms, the completion rate for both tests was

    2015-08-01

    Full Text Available Epithelial ovarian carcinoma is a disease with poor prognosis and high mortality among gynaecological cancers due to inaccessibility of ovary for inspection or sampling and lack of proper screening methods. Strategies to detect early ovarian cancer include estimation of serum CA-125 and transvaginal ultrasound (TVS for morphological index. Studies have shown that screening of asymptomatic average risk post-menopausal women did not show any benefit and are associated with false positive results which may lead to unnecessary surgery and resultant morbidity. The risks outweigh benefits. Present recommendation is to screen high risk women especially hereditary cancers and offer risk reducing surgery when needed. Prophylactic salpingectomy/oophorectomy may offer the opportunity to prevent ovarian cancer. More trials and more research in newer biomarkers are needed.

  19. Radiologic aspects of breast cancers detected through a breast cancer screening program

    International Nuclear Information System (INIS)

    Early detection in breast cancer and reduced mortality in women with this disease is today attributed to widespread use of mammography. High-quality performance is essential in all steps of breast cancer screening programs in order to avoid unnecessary anxiety and surgery in the women concerned. This report presents radiologic aspects of screening cancers. A total of 8370 asymptomatic women aged 50-69 years were screened with 2-view mammography, of which only 70 (0.84 percent) were selected for surgery after a thorough work-up. Cancers were verified histologically in 61 women and 9 showed non-malignant histology, giving a cancer detection rate of 7.3 cancers per thousand screened asymptomatic women. The benign/malignant ratio in the operated cases is thus approximately 1:7. The cancers detected showed all existing types of mammographic features where 77 percent (47 cases) showed rather typical findings, such as spiculated densities both with and without microcalcifications. The results indicate that surgery can be minimized without impairing the breast cancer detection rate. Radiologists in screening programs should be aware that a large proportion of non-palpable breast cancers present in rather unconventional forms. This point is important in order to maintain a high cancer detection rate and thereby justify the widespread use of mammography as a screening tool for breast cancer in asymptomatic women.

    2016-09-01

    This study investigates the cancer literacy level in Korean adults and examines whether cancer literacy plays a mediating role in the relationship between population characteristics and cancer screening behaviours. We collected data from 585 community-dwelling adults in Korea using self-administered surveys and face-to-face interviews from October to December in 2009. Guided by Andersen's behavioural model, we used a structural equation model to estimate the effect of cancer literacy as a mediator and found that cancer literacy mediated cancer screening behaviour. In the individual path analysis models, cancer literacy played a significant mediating role for the use of eastern medicine, fatalism, health status and the number of chronic diseases. When controlling for other relevant covariates, we found that in the optimal path model, cancer literacy played a mediating role in the relationship between the use of eastern medicine and self-rated health status as well as cancer screening behaviour. Thus, developing community-based cancer education programmes and training clinical practitioners in eastern medicine clinics about the importance of informing their patients about regular cancer screening may be an option to boost cancer literacy and screening behaviour in Korea.

    In French Guiana, the age-standardized incidence rate of cervical cancer is four times higher than in France and the mortality rate 5.5 times higher. A survival study revealed that stage at diagnosis was the main factor influencing the prognosis, showing that early detection is crucial to increase cervical cancer survival. The present study aimed at evaluating the cervical cancer screening rate between 2006 and 2011 by age and for a 3-year period in French Guiana. All pap smears realised in French Guiana were analysed in two laboratories allowing exhaustive review of screening data. The screening rate was estimated at about 54% from 2006 to 2011, with a statistical difference between coastal and rural area (56.3% versus 18.7%). Although the methodological difference did not allow comparisons with metropolitan France, these results could be used to evaluate the impact of organised cervical cancer screening by the French Guiana Association for Organized Screening of Cancers which has been implemented in French Guiana since 2012.

  6. Risk-benefit analysis for mass screening of breast cancer utilizing mammography as a screening test

    International Nuclear Information System (INIS)

    Incidence of breast cancers in Japanese women is increasing steadily. Mass screening of breast cancer was started in Japan under auspices of Adult Health Promotion Act of the Japanese Government from 1987. As the first screening method, the palpation of breasts is employed at present, but it is expected to be replaced by the mammography. In this report, the risk-benefit analysis is presented between risk of breast carcinogenesis due to radiation and benefit of mass screening of breast cancer. The benefit of mass screening is taken as the net elongation of average life expectancy of women due to survival from breast cancers. The risk of mammography is taken as the net loss of average life expectancy of women due to breast carcinogenesis. In the latter, the latency time and plateau period of radiation carcinogenesis were taken into consideration in the calculation. The results show that the ages at which the benefit and risk become equal are between 30 and 35 years old when dose equivalent of mammography is between 10 and 20 mSv, that are conventionally used. However, the critical age will be reduced to 20 years old if the dose equivalent becomes 1 mSv. Therefore, it is strongly recommended that a low dose mammographic system should be developed in order to achieve 1 mSv for the mass screening of breast cancer of Japanese women. In author's opinion, this is quite feasible by employing a new digital radiography with imaging plate. (author)

    On the basis of the National Lung Screening Trial data released in 2011, the U.S. Preventive Services Task Force made lung cancer screening (LCS) with low-dose computed tomography (CT) a public health recommendation in 2013. The Centers for Medicare and Medicaid Services (CMS) currently reimburse LCS for asymptomatic individuals aged 55-77 years who have a tobacco smoking history of at least 30 pack-years and who are either currently smoking or had quit less than 15 years earlier. Commercial insurers reimburse the cost of LCS for individuals aged 55-80 years with the same smoking history. Effective care for the millions of Americans who qualify for LCS requires an organized step-wise approach. The 10-pillar model reflects the elements required to support a successful LCS program: eligibility, education, examination ordering, image acquisition, image review, communication, referral network, quality improvement, reimbursement, and research frontiers. Examination ordering can be coupled with decision support to ensure that only eligible individuals undergo LCS. Communication of results revolves around the Lung Imaging Reporting and Data System (Lung-RADS) from the American College of Radiology. Lung-RADS is a structured decision-oriented reporting system designed to minimize the rate of false-positive screening examination results. With nodule size and morphology as discriminators, Lung-RADS links nodule management pathways to the variety of nodules present on LCS CT studies. Tracking of patient outcomes is facilitated by a CMS-approved national registry maintained by the American College of Radiology. Online supplemental material is available for this article.

    The literature on colorectal cancer (CRC screening is contradictory regarding the impact of weight status on CRC screening. This study was intended to determine if CRC screening rates among 2005 National Health Interview Survey (NHIS respondent racial/ethnic and gender subgroups were influenced by weight status. Methods. Univariable and multivariable logistic regression analyses were performed to determine if CRC screening use differed significantly among obese, overweight, and normal-weight individuals in race/ethnic and gender subgroups. Results. Multivariable analyses showed that CRC screening rates did not differ significantly for individuals within these subgroups who were obese or overweight as compared to their normal-weight peers. Conclusion. Weight status does not contribute to disparities in CRC screening in race/ethnicity and gender subgroups.

    Full Text Available Colorectal cancer (CRC is an important cause of mortality and morbidity in North America. Screening using a fecal occult blood test, flexible sigmoidoscopy, or colonoscopy reduces CRC mortality through the detection and treatment of precancerous polyps and early stage CRC. Although CRC screening participation has increased in recent years, large inequities still exist. Minorities, new immigrants, and those with lower levels of education or income are much less likely to be screened. This review provides an overview of the commonly used tests for CRC screening, disparities in CRC screening, and promising methods at the individual, provider, and system levels to reduce these disparities. Overall, to achieve high CRC participation rates and reduce the burden of CRC in the population, a multi-faceted approach that uses strategies at all levels to reduce CRC screening disparities is urgently required.

    Because informed consent for prostate cancer screening with prostate specific antigen (PSA) is recommended, we determined how African Americans, Hispanics, and Caucasians want information about screening with PSA and the digital rectal exam (DRE) presented in culturally sensitive brochures specific for each group. We analyzed focus group discussions using content analysis and compared themes across groups in a university outpatient internal medicine practice setting. The participants were twenty couples with men age 50 and older who participated in four focus groups. Main outcome measures were participants' views on the content and graphic design of culturally sensitive brochures promoting informed decision making about prostate cancer screening. There were content and graphic design differences in the way ethnic groups wanted information presented about the prostate, prostate cancer, risk, and screening. Caucasians likened the size of the prostate to a walnut; Hispanics, to a small lime. Hispanics emphasized how advanced prostate cancer can be symptomatic; Caucasians, how early prostate cancer can be asymptomatic. African Americans wanted risk information specific for them and the advantages and disadvantages of a PSA and DRE; Hispanics, did not. Caucasians and African Americans sought a more active role for men in informed decision making than Hispanics. Differences in the way African Americans, Hispanics, and Caucasians want information presented about prostate cancer screening suggest there may be cultural differences in the reasonable person standard of informed consent, in attitudes toward the physician-patient relationship, screening, and informed decision making. Physicians promoting informed decision making about controversial screening tests should take cultural sensitivity into account when designing educational interventions and using them. PMID:14620963

  12. Acute small bowel toxicity and preoperative chemoradiotherapy for rectal cancer: Investigating dose-volume relationships and role for inverse planning

    International Nuclear Information System (INIS)

    Purpose: The relationship between volume of irradiated small bowel (VSB) and acute toxicity in rectal cancer radiotherapy is poorly quantified, particularly in patients receiving concurrent preoperative chemoradiotherapy. Using treatment planning data, we studied a series of such patients. Methods and Materials: Details of 41 patients with locally advanced rectal cancer were reviewed. All received 45 Gy in 25 fractions over 5 weeks, 3-4 fields three-dimensional conformal radiotherapy with daily 5-fluorouracil and folinic acid during Weeks 1 and 5. Toxicity was assessed prospectively in a weekly clinic. Using computed tomography planning software, the VSB was determined at 5 Gy dose intervals (V5, V1, etc.). Eight patients with maximal VSB had dosimetry and radiobiological modeling outcomes compared between inverse and conformal three-dimensional planning. Results: VSB correlated strongly with diarrheal severity at every dose level (p 5 and V15. Conclusions: A strong dose-volume relationship exists between VSB and acute diarrhea at all dose levels during preoperative chemoradiotherapy. Our constructed model may be useful in predicting toxicity, and this has been derived without the confounding influence of surgical excision on bowel function. Inverse planning can reduce calculated dose to small bowel and late NTCP, and its clinical role warrants further investigation

    With the term "oncological screening", we define the overall performances made to detect early onset of tumors. These tests are conducted on a population that does not have any signs or symptoms related to a neoplasm. The whole population above a certain age, only one sex, only subjects with a high risk of developing cancer due to genetic, professional, discretionary reasons may be involved. Screening campaigns should be associated, when risk factors that can be avoided are known, with campaigns for the prevention of cancer by means of suitable behavior. The goal of cancer screening cannot however be limited to the diagnosis of a greater number of neoplasms. Screening will be useful only if it leads to a reduction in overall mortality or at least in mortality related to the tumor. Screening should then allow the diagnosis of the disease at a stage when there is a possibility of healing, possibility that is instead difficult when the disease is diagnosed at the appearance of signs or symptoms. This is the reason why not all campaigns of cancer screening have the same effectiveness. In Italy, every year there are about 150000 deaths due to cancer. Some of these tumors can be cured with a very high percentage of success if diagnosed in time. Cervical cancer can be diagnosed with non-invasive tests. The screening test used all over the world is Papanicolaou (Pap) test. This test may be carried out over the entire healthy population potentially exposed to the risk of contracting cancer. Public health has begun the screening campaigns in the hope of saving many of the approximately 270000 new cases of cancer reported each year. Screening is done following protocols that guarantee quality at the national level: these protocols are subject to change over time to reflect new realities or to correct any errors in the system. A simplified sketch of a possible route of cancer screening is as follows: (1) after selecting the target population, for example all women between 25

    Full Text Available The inflammatory bowel diseases (IBD, including Crohn’s disease and ulcerative colitis, are chronic inflammatory disorders of the intestine. The prevalence in the United States is greater than 200 cases per 100,000, with the total number of IBD patients between 1 and 1.5 million. Crohn’s disease may affect all parts of the gastrointestinal tract, from mouth to anus, but most commonly involves the distal part of the small intestine or ileum, and colon. Ulcerative colitis results in colonic inflammation that can affect the rectum only, or can progress proximally to involve part of or the entire colon. Clinical symptoms include diarrhea, abdominal pain, gastrointestinal bleeding and weight loss. A serious long-term complication of chronic inflammation is the development of colorectal cancer. A genetic basis for IBD had long been recognized based on the increased familial risk. However, significant discordance for Crohn’s disease in twins, and a much less robust phenotypic concordance for ulcerative colitis, suggested additional factors play a role in disease pathogenesis, including environmental factors. In the past several years, progress in understanding the molecular basis of IBD has accelerated, beginning with the generation of animal models of colitis and progressing to the identification of specific genetic markers from candidate gene, gene linkage and genome wide association analyses . Genetic studies have also resulted in the recognition of the importance of environmental factors, particularly the crucial role of the gut microbiota in Crohn’s disease and ulcerative colitis. Altered immune responses to the normal intestinal flora are key factors in IBD pathogenesis. In this Research Topic, the genetic basis of IBD, the genetic and cellular alterations associated with colitis-associated colon cancer, and the emerging role of the intestinal microbiota and other environmental factors will be reviewed.

    Pancreatic cancer exhibits an extraordinarily high level of resistance to almost any kind of systemic therapy evaluated in clinical trials so far. Therefore, the identification of novel therapeutic targets is urgently required. High-throughput screens have emerged as an important tool to identify putative targets for diagnosis and therapy in an unbiased manner. More than a decade ago, microarray technology was introduced to identify differentially expressed genes in pancreatic cancer as compared to normal pancreas, chronic pancreatitis and other cancer types located in close proximity to the pancreas. In addition, proteomic screens have facilitated the identification of differentially secreted proteins in body fluids of pancreatic cancer patients, serving as possible biomarkers. Recently, RNA interference-based loss-of-function screens have been used to identify functionally relevant genes, whose knock-down has impact on pancreatic cancer cell viability, thereby representing potential new targets for therapeutic intervention. This review summarizes recent results of transcriptional, proteomic and functional screens in pancreatic cancer and discusses potentials and limitations of the respective technologies as well as their impact on future therapeutic developments.

    2016-01-01

    Background: In March 2013, NHS England extended its national Bowel Cancer Screening Programme to include ‘one-off' Flexible Sigmoidoscopy screening (NHS Bowel Scope Screening, BSS) for men and women aged 55. With less than one in two people currently taking up the screening test offer, there is a strong public health mandate to develop system-friendly interventions to increase uptake while the programme is rolling out. This study aimed to assess the feasibility of sending a reminder to previous BSS non-responders, 12 months after the initial invitation, with consideration for its potential impact on uptake. Method: This study was conducted in the ethnically diverse London Boroughs of Brent and Harrow, where uptake is below the national average. Between September and November 2014, 160 previous non-responders were randomly selected to receive a reminder of the opportunity to self-refer 12 months after their initial invitation. The reminder included instructions on how to book an appointment, and provided options for the time and day of the appointment and the gender of the endoscopist performing the test. To address barriers to screening, the reminder was sent with a brief locally tailored information leaflet designed specifically for this study. Participants not responding within 4 weeks were sent a follow-up reminder, after which there was no further intervention. Self-referral rates were measured 8 weeks after the delivery of the follow-up reminder and accepted as final. Results: Of the 155 participants who received the 12 months' reminder (returned to sender, n=5), 30 (19.4%) self-referred for an appointment, of which 24 (15.5%) attended and were successfully screened. Attendance rates differed by gender, with significantly more women attending an appointment than men (20.7% vs 8.8%, respectively; OR=2.73, 95% CI=1.02–7.35, P=0.05), but not by area (Brent vs Harrow) or area-level deprivation. Of the 30 people who self-referred for an appointment, 27 (90

    Biomedical research cannot succeed without funding, knowledgeable staff, and appropriate infrastructure. There are however equally important but intangible factors that are rarely considered in planning large multidisciplinary endeavors or evaluating their success. The Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial required extensive collaborations between individuals from many fields, including clinicians, clinical trialists, and administrators; it also addressed questions across the spectrum of cancer prevention and control. In this manuscript, we examine the experiences and opinions of trial staff regarding the building of successful relationships in PLCO. We summarize, in narrative form, data collected using open-ended questionnaires that were administered to the National Cancer Institute project officers, coordinating center staff, screening center principal investigators, and screening center coordinators in 2015, about 3 years after publication of the final primary trial manuscript. Trust, respect, listening to others, and in-person interaction were frequently mentioned as crucial to building successful relationships.

    As patients with HIV age, they are at risk of developing non-AIDS defining malignancies. We performed a questionnaire study to evaluate colorectal and breast cancer screening among HIV-positive and HIV-negative patients seeking care from either an integrated (HIV/primary care), nonintegrated (specialized HIV), or general internal medicine clinic between August 2010 and July 2011. We performed a logistic regression to determine the odds of cancer screening. A total of 813 surveys were collected, and 762 were included in the analysis. As much as 401 were from HIV-positive patients. Patients with HIV were less likely to be current with their colorectal cancer screening (CRCS) (54.4% versus 65.0%, p=0.009); mammography rates were 24.3% versus 62.3% if done during the past year (pscreening in HIV-positive patients compared to negative controls was not statistically significant (OR 0.8; 95% CI 0.5-1.3); however, HIV-positive women remained significantly less likely to be current with breast cancer screening (BCS) whether their mammogram was completed within 1 year (OR 0.1, 95% CI 0.1-0.2) or within 5 years (OR 0.1, 95% CI 0.0-0.2). Integrated care was not associated with improved screening; however, having frequent visits to a primary care physician (PCP) increased the likelihood of getting screened. BCS was lower in HIV-positive compared to HIV-negative women. Frequent visits to a PCPs improved cancer screening.

    Full Text Available Background. Alaska Native people have nearly twice the rate of colorectal cancer (CRC incidence and mortality as the US White population. Objective. Building upon storytelling as a culturally respectful way to share information among Alaska Native people, a 25-minute telenovela-style movie, What's the Big Deal?, was developed to increase CRC screening awareness and knowledge, role-model CRC conversations, and support wellness choices. Design. Alaska Native cultural values of family, community, storytelling, and humor were woven into seven, 3–4 minute movie vignettes. Written post-movie viewing evaluations completed by 71.3% of viewers (305/428 were collected at several venues, including the premiere of the movie in the urban city of Anchorage at a local movie theater, seven rural Alaska community movie nights, and five cancer education trainings with Community Health Workers. Paper and pencil evaluations included check box and open-ended questions to learn participants' response to a telenovela-style movie. Results. On written-post movie viewing evaluations, viewers reported an increase in CRC knowledge and comfort with talking about recommended CRC screening exams. Notably, 81.6% of respondents (249/305 wrote positive intent to change behavior. Multiple responses included: 65% talking with family and friends about colon screening (162, 24% talking with their provider about colon screening (59, 31% having a colon screening (76, and 44% increasing physical activity (110. Conclusions. Written evaluations revealed the telenovela genre to be an innovative way to communicate colorectal cancer health messages with Alaska Native, American Indian, and Caucasian people both in an urban and rural setting to empower conversations and action related to colorectal cancer screening. Telenovela is a promising health communication tool to shift community norms by generating enthusiasm and conversations about the importance of having recommended colorectal

    AIM: To determine compliance to colorectal cancer(CRC) screening guidelines among persons with a family history of any type of cancer and investigate racial differences in screening compliance.METHODS: We used the 2007 Health Information National Trends Survey and identified 1094(27.4%)respondents(weighted population size = 21959672) without a family history of cancer and 3138(72.6%) respondents(weighted population size = 58201479) with a family history of cancer who were 50 years and older. We defined compliance with CRC screening as the use of fecal occult blood testing within 1 year, sigmoidoscopy within 5 years, or colonoscopy within 10 years. We compared compliance with CRC screening among those with and without a family member with a history of cancer. RESULTS: Overall, those with a family member with cancer were more likely to be compliant with CRC screening(64.9% vs 55.1%; OR = 1.45; 95%CI: 1.20-1.74). The absolute increase in screening rates associated with family history of cancer was 8.2% among whites. Hispanics had lowest screening rates among those without family history of cancer 41.9% but had highest absolute increase(14.7%) in CRC screening rate when they have a family member with cancer. Blacks had the lowest absolute increase in CRC screening(5.3%) when a family member has a known history of cancer. However, the noted increase in screening rates among blacks and Hispanics when they have a family member with cancer were not higher than whites without a family history of cancer:(54.5% vs 58.7%; OR = 1.16; 95%CI: 0.72-1.88) for blacks and(56.7% vs 58.7%; OR = 1.25; 95%CI: 0.72-2.18) for Hispanics.CONCLUSION: While adults with a family history of any cancer were more likely to be compliant with CRC screening guidelines irrespective of race/ethnicity, blacks and Hispanics with a family history of cancer were less likely to be compliant than whites without a family history. Increased burden from CRC among blacks may be related to poor uptake of

    Breast cancer still remains the most frequent cancer in women population. Incidence of breast cancer is increasing, but mortality is decreasing. The most important for decreasing of breast cancer mortality is early diagnostic, especially screening. Screening is a form of secondary prevention. Although many screening studies have shown that mammography decreases of the breast cancer death, there are still many controversies. The published recommendations for the breast screening are sometimes very different. (author)

    Clinical guidelines continue to move away from routine prostate specific antigen screening (PSA), once a widespread medical practice. A curious difference exists between early prostate cancer and early breast cancer. While randomized trials of therapy in early breast cancer continue to show overall survival benefit, this is not the case in prostate cancer, where prostatectomy was no better than observation in a recent trial, and where early androgen deprivation is no better than late androgen deprivation. Here, I make the case that prostate cancer screening contributes so greatly to over diagnosis that even treatment trials yield null results due to contamination with non-life threatening disease.

    Colorectal cancer (CRC) is now common in Thailand with an increase in incidence over time. Health authorities are planning to implement a nationwide CRC screening program using fecal immunochemical test (FIT) as a primary screening tool. This study aimed to estimate preferences and acceptance of FIT and colonoscopy, explore factors influencing the acceptance, and investigate reasons behind choosing and rejecting to screen before the program was implemented. Patients aged 50-69, visiting the primary care unit during the study period, were invited to join this study. Patients with a history of cancer or past CRC screening were excluded. Face-to-face interviews were conducted. Subjects were informed about CRC and the screening tests: FIT and colonoscopy. Then, they were asked for their opinions regarding the screening. The total number of subjects was 437 (86.7% response rate). Fifty-eight percent were females. The median age was 58 years. FIT was accepted by 74.1% of subjects compared to 55.6% for colonoscopy. The acceptance of colonoscopy was associated with perceived susceptibility to CRC and family history of cancer. No symptoms, unwilling to screen, healthy, too busy and anxious about diagnosis were reasons for refusing to screen. FIT was preferred for its simplicity and non-invasiveness compared with colonoscopy. Those rejecting FIT expressed a strong preference for colonoscopy. Subjects chose colonoscopy because of its accuracy; it was refused for the process and complications. If the screening program is implemented for the entire target population in Thailand, we estimate that 106,546 will have a positive FIT, between 8,618 and 12,749 identified with advanced adenoma and between 2,645 and 3,912 identified with CRC in the first round of the program.

Main findings Ontario administrative data on CRC screening showed lower overall screening rates among those who were younger, male patients, those who had lower income, and recent immigrants. Colonoscopy rates were especially low among those with lower income and those who were recent immigrants. Semistructured interviews revealed that physician opinions about CRC screening for average-risk patients were divided: one group of physicians accepted the evidence and recommendations for FOBT and the other group of physicians strongly supported colonoscopy for these patients, believing that the FOBT was an inferior screening method. Physicians identified specialist recommendations and patient expectations as factors that influenced their decisions regarding CRC screening type. Conclusion There was considerable variation in CRC screening by sociodemographic characteristics. A key theme that emerged from the interviews was that physicians were divided in their preference for FOBT or colonoscopy; factors that influenced physician preference included the health care system, recommendations by other

  14. New Molecular Tools for Efficient Screening of Cervical Cancer

    Full Text Available Cytological screening using the Pap-smear led to a remarkable reduction of the mortality of cervical cancer. However, due to subjective test criteria it is hampered by poor inter- and intra-observer agreement. More reproducible assays are expected to improve the current screening and avoid unnecessary medical intervention and psychological distress for the affected women. Cervical cancer arises as consequence of persistent high risk papillomavirus (HR-HPV infections. Expression of two viral oncogenes, E6 and E7, in epithelial stem cells is required to initiate and maintain cervical carcinogenesis and results in significant overexpression of the cellular p16INK4a protein. Since this protein is not expressed in normal cervical squamous epithelia, screening for p16INK4a over-expressing cells allows to specifically identify dysplastic lesions, and significantly reduces the inter-observer disagreement of the conventional cytological or histological tests. Progression of preneoplastic lesions to invasive cancers is associated with extensive recombination of viral and cellular genomes which can be monitored by detection of papillomavirus oncogene transcripts (APOT assay derived from integrated viral genome copies. Detection of integrated type oncogene transcripts points to far advanced dysplasia or invasive cancers and thus represents a progression marker for cervical lesions. These new assays discussed here will help to improve current limitations in cervical cancer screening, diagnosis, and therapy control.

    Lung cancer is the most frequently fatal cancer, with poor survival once the disease is advanced. Annual low dose computed tomography has shown a survival benefit in screening individuals at high risk for lung cancer. Based on the available evidence, the European Society of Radiology and the European Respiratory Society recommend lung cancer screening in comprehensive, quality-assured, longitudinal programmes within a clinical trial or in routine clinical practice at certified multidisciplinary medical centres. Minimum requirements include: standardised operating procedures for low dose image acquisition, computer-assisted nodule evaluation, and positive screening results and their management; inclusion/exclusion criteria; expectation management; and smoking cessation programmes. Further refinements are recommended to increase quality, outcome and cost-effectiveness of lung cancer screening: inclusion of risk models, reduction of effective radiation dose, computer-assisted volumetric measurements and assessment of comorbidities (chronic obstructive pulmonary disease and vascular calcification). All these requirements should be adjusted to the regional infrastructure and healthcare system, in order to exactly define eligibility using a risk model, nodule management and quality assurance plan. The establishment of a central registry, including biobank and image bank, and preferably on a European level, is strongly encouraged. PMID:25929956

  17. Breast cancer screening; cost-effective in practice?

    International Nuclear Information System (INIS)

    The main aim of national breast screening is a reduction in breast cancer mortality. The data on the reduction in breast cancer mortality from three (of the five) Swedish trials in particular gave rise to the expectation that the Dutch programme of 2-yearly screening for women aged 50-70 would produce a 16% reduction in the total population. In all likelihood, many of the years of life gained as a result of screening are enjoyed in good health. According to its critics the actual benefit that can be achieved from the national breast cancer screening programmes is overstated. Considerable benefits have recently been demonstrated in England and Wales. However, the fall was so considerable in such a relatively short space of time that screening (started in 1987) was thought to only have played a small part. As far as the Dutch screening programme is concerned it is still too early to reach any conclusions about a possible reduction in mortality. The first short-term results of the screening are favourable and as good as (or better than) expectations. In Swedish regions where mammographic screening was introduced, a 19% reduction in breast cancer mortality can be estimated at population level, and recently a 20% reduction was presented in the UK. In countries where women are expected to make appointments for screening themselves, the attendance figures are significantly lower and the quality of the process as a whole is sometimes poorer. The benefits of breast cancer screening need to be carefully balanced against the burden to women and to the health care system. Mass breast screening requires many resources and will be a costly service. Cost-effectiveness of a breast cancer screening programme can be estimated using a computer model. Published cost-effectiveness ratios may differ tremendously, but are often the result of different types of calculation, time periods considered, including or excluding downstream cost. The approach of simulation and estimation is here

    Worldwide, lung cancer is the leading cause of mortalitydue to malignancy. The vast majority of cases of lung cancer are smoking related and the most effective way of reducing lung cancer incidence and mortality is by smoking cessation. In the Western world, smoking cessation policies have met with limited success. The other major means of reducing lung cancer deaths is to diagnose cases at an earlier more treatable stage employing screening programmes using chest radiographs or low dose computed tomography. In many countries smoking is still on the increase, and the sheer scale of the problem limits the affordability of such screening programmes. This short review article will evaluate the current evidence and potential areas of research which may benefit policy making across the world.

    Lung cancer remains the leading cause of cancer-related death in the United States. An effective screening tool for early lung cancer detection has long been sought. Early chest radiograph and low-dose computed tomography (LDCT) screening trials were promising and demonstrated increased cancer detection. However, these studies were not able to improve lung cancer mortality. The National Lung Screening Trial resulted in decreased lung cancer mortality with LDCT screening in a high-risk population. Similar trials are currently underway in Europe. With LDCT now being widely implemented, it is paramount for radiologists to understand the evidence for lung cancer screening.

    Small bowel (SB) is an organ at risk (OAR) that may potentially develop toxicity after radiotherapy for cervix cancer. However, its dose from brachytherapy (BT) is not systematically reported as in other OARs, even with image-guided brachytherapy (IGBT). This study aims to introduce consideration of quantified objectives for SB in BT plan optimization and to evaluate the feasibility of sparing SB while maintaining adequate target coverage. In all, 13 patients were included in this retrospective study. All patients were treated with external beam radiotherapy (EBRT) 45Gy in 25 fractions followed by high dose rate (HDR)-BT boost of 28Gy in 4 fractions using tandem/ring applicator. Magnetic resonance imaging (MRI) and computed tomographic (CT) images were obtained to define the gross tumor volume (GTV), high-risk clinical target volume (HR-CTV) and OARs (rectum, bladder, sigmoid colon, and SB). Treatment plans were generated for each patient using GEC-ESTRO recommendations based on the first CT/MRI. Treatment plans were revised to reduce SB dose when the [Formula: see text] dose to SB was > 5Gy, while maintaining other OAR constraints. For the 7 patients with 2 sets of CT and MRI studies, the interfraction variation of the most exposed SB was analyzed. Plan revisions were done in 6 of 13 cases owing to high [Formula: see text] of SB. An average reduction of 19% in [Formula: see text] was achieved. Meeting SB and other OAR constraints resulted in less than optimal target coverage in 2 patients (D90 of HR-CTV < 77Gyαβ10). The highest interfraction variation was observed for SB at 16 ± 59%, as opposed to 28 ± 27% for rectum and 21 ± 16% for bladder. Prospective reporting of SB dose could provide data required to establish a potential correlation with radiation-induced late complication for SB. PMID:26235549

    Objectives To determine the types of, and the populations targeted by interventions implemented to increase breast cancer screening rates in counties with large African American populations across different US regions. Methods A brief questionnaire was administered by e-mail to county representatives from 33 states from October 2008 through March 2009. Responses were obtained from 33% of 203 targeted counties. Results Most counties (>80%) reported interventions for African American women and for women with low income. Women were exposed to different kinds of interventions depending on where they lived. Most counties in the Northeast (93%), Southwest (82%) and Midwest (100%) implemented interventions that provided free or low cost mammograms. Counties in the Southeast (83%) were more likely to report education interventions. Counties from the Southwest reported using a variety of interventions to encourage breast cancer screening. Conclusion In this selected group of counties, different types of interventions were used to increase breast cancer screening in minority and disadvantaged women. Interventions implemented were similar to those shown in the literature to be effective in increasing screening rates in specific populations. Future research should examine the use of screening interventions in a larger sample of US counties. PMID:20820899

  10. Cervical cancer screening in Belgium and overscreening of adolescents.

    Science.gov (United States)

    Van Kerrebroeck, Helena; Makar, Amin

    2016-03-01

    There has been a marked decrease in the incidence of cervical cancer thanks to cytological screening with the Pap smear test. In Belgium, this screening is rather opportunistic. Over 39% of Belgian women between 25 and 64 years of age are never or only rarely screened by cytological tests. Moreover, there is an excess use of Pap smears because of women who rely on their yearly cervical smear and because many Pap smears are obtained from women beyond the target age range of 25 to 64 years. Sexually active adolescents are increasingly being recognized as a population distinct from adult women. They are at a high risk of acquiring the human papillomavirus (HPV), but most infections and cervical intraepithelial lesions caused by HPV are efficiently cleared by the immune system. We present a description of cervical cancer screening in Belgium using the database of the National Health Insurance Institute (RIZIV/INAMI) and the Belgian Health Care Knowledge Centre (KCE). We describe why elimination of Pap testing in the adolescent population reduces costs and harms without increasing cervical cancer rates. Expectant management, education on the risk factors for cervical cancer and HPV persistence, and HPV vaccination are very important in adolescents and young adults. PMID:25812038

    2009-10-15

    Adequate screening methods can decrease colorectal cancer (CRC) mortality. The guaiac test for fecal occult-blood (FOBT) is part of the German CRC Screening Program since 1970 and has evidence level Ia. In randomized multicenter-studies FOBT has an average sensitivity of 24% and decreases CRC mortality up to 30%. Immunological tests for human haemoglobin (iFOBT) show better performance characteristics than guaiac FOBT, with augmented sensitivity and specificity. However, the single tests show wide differences in diagnostic performance and iFOBT is not yet covered by insurance companies although it should replace the guaiac test for CRC screening. Visual colonoscopy, which was introduced to the German National Cancer Screening Program in 2002, is the gold standard for the diagnosis of colorectal neoplasia. From 2003 to 2007 more than 2.8 million examinations have been documented in Germany. The prevalence of adenomas is around 20% and of CRC about 0.7% to 1.0% of the screenings. Seventy percent of the carcinomas detected during screening are in an early stage (UICC I and II). Furthermore, screening colonoscopy is a cost saving procedure with a low complication rate (0.25% overall). Insurance companies save 216€ for each screening colonoscopy mainly by prevention of neoplasia due to polypectomy. In Germany, virtual colonography by computed tomography (CT) or magnetic resonance imaging still lacks standardization of the hard and software. In experienced centres the sensitivity for CRC and large polyps of CT colonography is comparable to colonoscopy but in meta-analyses the ranking is lower. New technologies like computer-aided colonoscopies with sheath or double balloon techniques are coming up as well as capsule colonoscopy, which sensitivity for large polyps is about 70%. Advised by his physician, the patient can choose his most acceptable examination method from this whole set of screening tools.

    2015-01-01

    Radiology administrators must use innovative strategies around clinical collaboration and marketing to ensure that patients access the service in sufficient numbers. Radiology Associates of South Florida in collaboration with Baptist Health South Florida have developed a successful lung cancer screening program. The biggest factors in their success have been the affordability of their service and the quality of the program. Like mammography, lung cancer screening programs serve as an entry point to other services that generate revenue for the hospital. Patients may require further evaluation in the form of more imaging or surgical services for biopsy. Part 1 provided background and laid out fundamentals for starting a program. Part 2 focuses on building patient volume, marketing, and issues related to patient management after the screen is performed. PMID:26314180

    Colorectal cancer (CRC) can be effectively prevented via screening colonoscopy, yet adherence rates remain low among Latinos. Interventions targeting individual and cultural barriers to screening are needed. We developed an educational brochure to target these barriers faced by a diverse Latino population. The objective was to evaluate the responses of the target population to the culturally and theoretically informed brochure through community member focus groups. Facilitators conducted six focus groups, stratified by gender, language, and prior colonoscopy experience. Topics included: brochure content and layout, cancer knowledge, and CRC screening determinants. Focus groups documented community members' responses to the brochure's overall message and its informational and visual components. Changes to wording, visual aids, and content were suggested to make the brochure culturally more acceptable. Results indicated relevance of the theoretically and culturally guided approach to the development of the brochure leading to refinement of its content and design.

  8. Ultrasound screening of contralateral breast after surgery for breast cancer

    International Nuclear Information System (INIS)

    Highlights: • The addition of supplemental US to mammography depicted additional 5.0 cancers per 1000 postoperative women. • Positive biopsy rate of mammography-detected lesions was 66.7% (4 of 6) and that of US-detected lesions was 40.0% (6 of 15). • US can be helpful to detect mammographically occult breast cancer in the contralateral breast in women with previous history of cancer and dense breast. - Abstract: Objective: To determine whether supplemental screening ultrasound (US) to mammography could improve cancer detection rate of the contralateral breast in patients with a personal history of breast cancer and dense breasts. Materials and methods: During a one-year study period, 1314 screening patients with a personal history of breast cancer and dense breasts simultaneously underwent mammography and breast US. BI-RADS categories were given for mammography or US-detected lesions in the contralateral breast. The reference standard was histology and/or 1-year imaging follow-up, and the cancer rate according to BI-RADS categories and cancer detection rate and positive biopsy rate according to detection modality were analyzed. Results: Of 1314 patients, 84 patients (6.4%) were categorized as category 3 with one interval cancer and one cancer which was upgraded to category 4A after 6-month follow-up US (2.5% cancer rate, 95% CIs 1.5–9.1%). Fifteen patients (1.1%) had category 4A or 4B lesions in the contralateral breast. Four lesions were detected on mammography (two lesions were also visible on US) and 11 lesions were detected on US and 5 cancers were confirmed (33.3%, 95% CIs 15.0–58.5%).

    Highlights: • The addition of supplemental US to mammography depicted additional 5.0 cancers per 1000 postoperative women. • Positive biopsy rate of mammography-detected lesions was 66.7% (4 of 6) and that of US-detected lesions was 40.0% (6 of 15). • US can be helpful to detect mammographically occult breast cancer in the contralateral breast in women with previous history of cancer and dense breast. - Abstract: Objective: To determine whether supplemental screening ultrasound (US) to mammography could improve cancer detection rate of the contralateral breast in patients with a personal history of breast cancer and dense breasts. Materials and methods: During a one-year study period, 1314 screening patients with a personal history of breast cancer and dense breasts simultaneously underwent mammography and breast US. BI-RADS categories were given for mammography or US-detected lesions in the contralateral breast. The reference standard was histology and/or 1-year imaging follow-up, and the cancer rate according to BI-RADS categories and cancer detection rate and positive biopsy rate according to detection modality were analyzed. Results: Of 1314 patients, 84 patients (6.4%) were categorized as category 3 with one interval cancer and one cancer which was upgraded to category 4A after 6-month follow-up US (2.5% cancer rate, 95% CIs 1.5–9.1%). Fifteen patients (1.1%) had category 4A or 4B lesions in the contralateral breast. Four lesions were detected on mammography (two lesions were also visible on US) and 11 lesions were detected on US and 5 cancers were confirmed (33.3%, 95% CIs 15.0–58.5%). Six patients (0.5%) had category 4C lesions, 2 detected on mammography and 4 on US and 4 cancers were confirmed (66.7%, 95% CIs 29.6–90.8%). No lesions were categorized as category 5 in the contralateral breast.

  10. Population screening for breast cancer in the European Community

    International Nuclear Information System (INIS)

    Although our understanding of the causes of breast cancer is increasing, it is as yet not possible to recommend measures to decrease its occurrence. Therefore we have to resort to a substitute called secondary prevention which aims at preventing the occurrence of metastatic breast cancer and death by detecting the primary cancer in the breast at an earlier point in its natural history. The question whether this can be achieved can only be answered by scientific study. Such studies are being called: population-based screening programmes. Screening requires one or more tests by which one can partition a population in those who probably have a cancer and those who have not. Since an early breast cancer does not produce symptoms like pain the test has to be some sort of objective assessment. In the field of detecting breast cancer we have been greatly helped by the development of a radiologic technique called mammography. Mammography basically is not an easy technique since there is little contrast between structures in the breast compared with e.g. bone. The quality of mammograms, therefore, was not very high in the pioneering era during the nineteen-fifties and -sixties. This presentation discusses a move of a few doctors in New York city: a radiologist, a surgeon and epidemiologist, to design a scientific study which could answer the question whether mammography, added to a standard clinical examination of the breast would decrease mortality from breast cancer

    Development of a workshop on skin cancer screening should begin with physicians who are able to best diagnose and treat skin cancer, that is, dermatologists who are board certified or board eligible. Local societies should then be involved as well as organizations that can offer ancillary help such as screening, clinics' location and assisting with personnel financial aid, and exposure to the public, such as advertising. Support groups then become essential to a good screening. The help of the American Cancer Society, local churches, clubs, and others is beneficial. The organization should have a central organizing body that sets the dates and locations for the clinics and that helps get supplies, such as tables, screens for privacy, and literature. Volunteers can help with sign-in and sign-out sheets for the screening and can act as traffic directors and assist the physicians. Media exposure then becomes important. A TV or radio show can get the public's attention, for example, by releasing the latest data on skin cancer or by presenting a solar meter project showing the local risk of ultraviolet radiation. The workshop itself should begin on time. Additionally, a cutoff time is also needed. In the final stage, the forms should be processed and a follow-up evaluation should be done on the number of patients seen, precancerous and cancerous lesions found, and the potential for future functions. Popular ancillary aids are good literature on the subjects discussed, and samples of sunscreens (SPF 15 or better) that are donated by pharmaceutical companies. PMID:7804998

    Full Text Available Abstract Background Appropriate screening may reduce the mortality and morbidity of colorectal, breast, and cervical cancers. However, effective implementation strategies are warranted if the full benefits of screening are to be realized. As part of a larger agenda to create an implementation guideline, we conducted a systematic review to evaluate interventions designed to increase the rate of breast, cervical, and colorectal cancer (CRC screening. The interventions considered were: client reminders, client incentives, mass media, small media, group education, one-on-one education, reduction in structural barriers, reduction in out-of-pocket costs, provider assessment and feedback interventions, and provider incentives. Our primary outcome, screening completion, was calculated as the overall median post-intervention absolute percentage point (PP change in completed screening tests. Methods Our first step was to conduct an iterative scoping review in the research area. This yielded three relevant high-quality systematic reviews. Serving as our evidentiary foundation, we conducted a formal update. Randomized controlled trials and cluster randomized controlled trials, published between 2004 and 2010, were searched in MEDLINE, EMBASE and PSYCHinfo. Results The update yielded 66 studies new eligible studies with 74 comparisons. The new studies ranged considerably in quality. Client reminders, small media, and provider audit and feedback appear to be effective interventions to increase the uptake of screening for three cancers. One-on-one education and reduction of structural barriers also appears effective, but their roles with CRC and cervical screening, respectively, are less established. More study is required to assess client incentives, mass media, group education, reduction of out-of-pocket costs, and provider incentive interventions. Conclusion The new evidence generally aligns with the evidence and conclusions from the original systematic

    Full Text Available OBJECTIVE To analyze the coverage of a cervical cancer screening program in a city with a high incidence of the disease in addition to the factors associated with non-adherence to the current preventive program. METHODS A cross-sectional study based on household surveys was conducted. The sample was composed of women between 25 and 59 years of age of the city of Boa Vista, RR, Northern Brazil who were covered by the cervical cancer screening program. The cluster sampling method was used. The dependent variable was participation in a women’s health program, defined as undergoing at least one Pap smear in the 36 months prior to the interview; the explanatory variables were extracted from individual data. A generalized linear model was used. RESULTS 603 women were analyzed, with an mean age of 38.2 years (SD = 10.2. Five hundred and seventeen women underwent the screening test, and the prevalence of adherence in the last three years was up to 85.7% (95%CI 82.5;88.5. A high per capita household income and recent medical consultation were associated with the lower rate of not being tested in multivariate analysis. Disease ignorance, causes, and prevention methods were correlated with chances of non-adherence to the screening system; 20.0% of the women were reported to have undergone opportunistic and non-routine screening. CONCLUSIONS The informed level of coverage is high, exceeding the level recommended for the control of cervical cancer. The preventive program appears to be opportunistic in nature, particularly for the most vulnerable women (with low income and little information on the disease. Studies on the diagnostic quality of cervicovaginal cytology and therapeutic schedules for positive cases are necessary for understanding the barriers to the control of cervical cancer.

  2. Effects of repeated mammographic screening on breast cancer stage distribution

    International Nuclear Information System (INIS)

    A randomised controlled trial of mass screening for breast cancer by single-view mammography was begun in Sweden in 1977. All women aged 40 and older and resident in the counties of Koppaberg and Oestergoetland were enrolled. The present report is confined to the Oestergoetland study, which started in 1978 and comprised 92934 women. After randomisation, which was done on the basis of communities rather than individuals, 47001 women were allocated to the study group and offered repeated mammographic screening; 45933 were allocated to the control group. As compliance among women over 74 years of age was poor these were excluded from the present report. The yearly incidence of stage II or more advanced breast cancers after the initial screening round up to and including the second was reduced by 40 per cent in the study group compared with the controls. This effect was less marked in the age group 40-49. After 5.5 years average from the date of entry the absolute number of women with stage II-IV disease in the control group exceeded that for the study group by 44, whereas there was a large excess of cancer in situ and stage I cancer in the study group.

    South Asian (SA) immigrants settled in the United Kingdom (UK) and North America [United States (US) and Canada] have low screening rates for breast, cervical and colorectal cancers. Incidence rates of these cancers increase among SA immigrants after migration, becoming similar to rates in non-Asian native populations. However, there are disparities in cancer screening, with low cancer screening uptake in this population. We conducted a scoping study using Arksey & O'Malley's framework to examine cancer screening literature on SA immigrants residing in the UK, US and Canada. Eight electronic databases, key journals and reference lists were searched for English language studies and reports. Of 1465 identified references, 70 studies from 1994 to November 2014 were included: 63% on breast or cervical cancer screening or both; 10% examined colorectal cancer screening only; 16% explored health promotion/service provision; 8% studied breast, cervical and colorectal cancer screening; and 3% examined breast and colorectal cancer screening. A thematic analysis uncovered four dominant themes: (i) beliefs and attitudes towards cancer and screening included centrality of family, holistic healthcare, fatalism, screening as unnecessary and emotion-laden perceptions; (ii) lack of knowledge of cancer and screening related to not having heard about cancer and its causes, or lack of awareness of screening, its rationale and/or how to access services; (iii) barriers to access including individual and structural barriers; and (iv) gender differences in screening uptake and their associated factors. Findings offer insights that can be used to develop culturally sensitive interventions to minimise barriers and increase cancer screening uptake in these communities, while recognising the diversity within the SA culture. Further research is required to address the gap in colorectal cancer screening literature to more fully understand SA immigrants' perspectives, as well as research to

    Cancer is a critical disease with a high mortality rate in the US. Although useful information exists on the Internet, many people experience difficulty finding information about cancer prevention because they have limited eHealth literacy. This study aimed to identify relationships between the level of eHealth literacy and cancer information seeking experience or prior experience with cancer screening tests. A total of 108 adults participated in this study through questionnaires. Data covering demographics, eHealth literacy, cancer information seeking experience, educational needs for cancer information searching, and previous cancer screening tests were obtained. Study findings show that the level of eHealth literacy influences cancer information seeking. Individuals with low eHealth literacy are likely to be less confident about finding cancer information. In addition, people who have a low level of eHealth literacy need more education about seeking information than do those with a higher level of eHealth literacy. However, there is no significant relationship between eHealth literacy and cancer screening tests. More people today are using the Internet for access to information to maintain good health. It is therefore critical to educate those with low eHealth literacy so they can better self-manage their health.

    Unprecedented progress has been made in genomic personalized medicine in the last several years, allowing for more individualized healthcare assessments and recommendations than ever before. However, most of this progress in prostate cancer (PCa) care has focused on developing and selecting therapies for late-stage disease. To address this issue of limited focus, we propose a model for incorporating genomic-based personalized medicine into all levels of PCa care, from prevention and screening to diagnosis, and ultimately to the treatment of both early-stage and late-stage cancers. We have termed this strategy the "Pyramid Model" of personalized cancer care. In this perspective paper, our objective is to demonstrate the potential application of the Pyramid Model to PCa care. This proactive and comprehensive personalized cancer care approach has the potential to achieve three important medical goals: reducing mortality, improving quality of life and decreasing both individual and societal healthcare costs.

    Full Text Available Abstract Background U.S. cancer screening guidelines communicate important information regarding the ages for which screening tests are appropriate. Little attention has been given to whether breast, colorectal and prostate cancer screening test use is responsive to guideline age information regarding the age of screening initiation. Methods The 2006 Behavioral Risk Factor Social Survey and the 2003 National Health Interview Surveys were used to compute breast, colorectal and prostate cancer screening test rates by single year of age. Graphical and logistic regression analyses were used to compare screening rates for individuals close to and on either side of the guideline recommended screening initiation ages. Results We identified large discrete shifts in the use of screening tests precisely at the ages where guidelines recommend that screening begin. Mammography screening in the last year increased from 22% [95% CI = 20, 25] at age 39 to 36% [95% CI = 33, 39] at age 40 and 47% [95% CI = 44, 51] at age 41. Adherence to the colorectal cancer screening guidelines within the last year increased from 18% [95% CI = 15, 22] at age 49 to 19% [95% CI = 15, 23] at age 50 and 34% [95% CI = 28, 39] at age 51. Prostate specific antigen screening in the last year increased from 28% [95% CI = 25, 31] at age 49 to 33% [95% CI = 29, 36] and 42% [95% CI = 38, 46] at ages 50 and 51. These results are robust to multivariate analyses that adjust for age, sex, income, education, marital status and health insurance status. Conclusion The results from this study suggest that cancer screening test utilization is consistent with guideline age information regarding the age of screening initiation. Screening test and adherence rates increased by approximately 100% at the breast and colorectal cancer guideline recommended ages compared to only a 50% increase in the screening test rate for prostate cancer screening. Since information regarding the age of cancer screening

  10. 5-aminosalicylic acid is an attractive candidate agent for chemoprevention of colon cancer in patients with inflammatory bowel disease

    Yang Cheng; Pierre Desreumaux

    2005-01-01

    Inflammatory bowel disease (IBD) is classically subdivided into ulcerative colitis (UC) and Crohn's disease (CD). Patients with IBD have increased risk for colorectal cancer. Because the pathogenesis of colorectal carcinoma has not been entirely defined yet and there is no ideal treatment for colon cancer, cancer prevention has become increasingly important in patients with IBD. The two adopted methods to prevent the development of colon cancer in clinical practice include the prophylactic colectomy and colonoscopic surveillance.But patients and physicians seldom accept colectomy as a routine preventive method and most patients do not undergo appropriate colonoscopic surveillance. Chemoprevention refers to the use of natural or synthetic chemical agents to reverse, suppress, or to delay the process of carcinogenesis.Chemoprevention is a particularly useful method in the management of patients at high risk for the development of specific cancers based on inborn genetic susceptibility, the presence of cancer-associated disease, or other known risk factors. Prevention of colorectal cancer by administration of chemopreventive agents is one of the most promising options for IBD patients who are at increased risks of the disease. The chemopreventive efficacy of nonsteroidal antiinflammatory drugs (NSAIDs) against intestinal tumors has been well established. But with reports that NSAIDs aggravated the symptoms of colitis, their sustained use for the purpose of cancer chemoprevention has been relatively contraindicated in IBD patients. Another hopeful candidate chemoprevention drug for IBD patients is 5-aminosalicylic acid (5-ASA), which is well tolerated by most patients and has limited systemic adverse effects, and no gastrointestinal toxicity. 5-ASA lacks the well-known side effects of longterm NSAIDs use. Retrospective correlative studies have suggested that the long-term use of 5-ASA in IBD patients may significantly reduce the risk of development of colorectal cancer

    Human bocavirus (HBoV) is a prevalent virus worldwide and is mainly associated with respiratory disorders. Recently, it was detected in several disease conditions, including cancers. Colorectal cancer (CRC) is the third main cause of cancers worldwide. Risk factors that initiate cell transformation include nutritional, hereditary and infectious causes. The aim of the current study was to screen for the presence of HBoV in solid tumors of colorectal cancer and to determine the genotypes of the detected strains. Surgically excised and paraffin-embedded colorectal cancer tissue specimens from 101 male and female patients with and without metastasis were collected over the last four years. Pathological analysis and tumor stages were determined. The presence of HBoV was screened by polymerase chain reaction, and the genotype of the detected HBoV was determined by direct gene sequencing. Most of the examined specimens were adenocarcinoma with mucinous activity in many of them. Twenty-four out of 101 (23.8 %) CRC tissue specimens were found to contain HBoV-1. Low sequence diversity was recorded in the detected strains. The virus was detected in both male and female patients with an age range of 30-75 years. It is proposed that HBoV-1 could play a potential role in the induction of CRC. PMID:27155943

    Immigrant populations in the United States (US) have lower cancer screening rates compared to none immigrant populations. The purpose of this study was to assess the rates of cancer screening and examine factors associated with cancer screening behavior among African immigrant women in Minnesota. A cross sectional survey of a community based sample was conducted among African immigrants in the Twin Cities. Cancer screening outcome measures were mammography and Papanicolau smear test. The revised theoretical model of health care access and utilization and the behavioral model for vulnerable populations were utilized to assess factors associated with cancer screening. Only 61 and 52% of the age eligible women in the sample had ever been screened for breast and cervical cancer respectively. Among these women, duration of residence in the US and ethnicity were significant determinants associated with non-screening. Programs to enhance screening rates among this population must begin to address barriers identified by the community.

    Purpose. Radiation enteritis is the main acute side-effect during pelvic irradiation. The aim of this study was to quantify the dose-volume relationship between irradiated bowel volumes and acute enteritis during combined chemoradiotherapy for rectal cancer. Material and methods. Twenty-eight patients with locally advanced rectal cancer received chemoradiotherapy. The radiation therapy was given with a traditional multi-field technique to a total dose of 50 Gy, with concurrent 5-Fluorouracil (5-FU) and oxaliplatin (OXA) based chemotherapy. All patients underwent three-dimensional CT-based treatment planning. Individual loops of small and large bowel as well as a volume defined as 'whole abdomen' were systematically contoured on each CT slice, and dose-volume histograms were generated. Diarrhea during treatment was scored retrospectively according to the NCI Common Toxicity Criteria scale. Results. There was a strong correlation between the occurrence of grade 2+diarrhea and irradiated small bowel volume, most notably at doses >15 Gy. Neither irradiated large bowel volume, nor irradiated 'whole abdomen' volume correlated significantly with diarrhea. Clinical or treatment related factors such as age, gender, hypertension, previous surgery, enterostomy, or dose fractionation (1.8 vs. 2.0 Gy/fraction) did not correlate with grade 2+diarrhea. Discussion. This study indicates a strong dose-volume relationship between small bowel volume and radiation enteritis during 5-FU-OXA-based chemoradiotherapy. These findings support the application of maneuvers to minimize small bowel irradiation, such as using a 'belly board' or the use of IMRT technique aiming at keeping the small bowel volume receiving more than 15 Gy under 150 cc.

  18. Results of lung cancer screening in atomic bomb survivors

    International Nuclear Information System (INIS)

    Risk of lung cancer in A-bomb survivors is reportedly increased. The screening in the title has been conducted since 1988 and this report summarizes its results of the latest 6-year term (2004-2009). The total number of subjects who visited authors' facility for the screening in the period was 39,147 men (average age 70.6 y) and 45,351 women (71.8 y), of the age range of 60-89 y. The screening results of the cancer were examined concerning with sex, age and exposure situation. As well, the relationship between the found cancer incidence and exposure in never, formerly and currently smoking subjects were also examined. Exposure situation was divided in 3 groups of the exposure by entrance in the city/by other reasons, within 2 km close (Close, C) to, and out of 2.1 km afar (Distant, D) from, the city. Statistic analysis was performed by Chi-squire and/or Fisher's exact test. The index of positive finding in the screening of the lung cancer per 1,000 subjects was the highest in C men of ages 70s, 2.88 subjects, which was statistically significant from 0.85 in D men of the same generation. In current smokers, the index 5.40 in C men of ages 70s was significantly higher than 0.90 in D men of the same generation. Overall, positive results tended to be high in survivors of C regardless to sex and smoking, and was significantly high in current smokers of C as above, both implying the particular necessity of promotion to stop smoking in survivors.

    The prevailing questions at this time in both the public mind and the clinical establishment is, do we have sufficient evidence to implement lung cancer Computed Tomography (CT) screening in Europe? If not, what is outstanding? This review addresses the twelve major areas, which are critical to any decision to implement CT screening and where we need to assess whether we have sufficient evidence to proceed to a recommendation for implementation in Europe. The readiness level of these twelve categories in 2015 have been with colour coded, where green indicates we have sufficient evidence, amber is borderline evidence and red requires further evidence. Recruitment from the 'Hard to Reach' community still remains at red, while mortality data, cost effectiveness and screening interval are all categorised as amber. The integration of smoking cessation into CT screening programmes is still considered to be category amber. The US Preventive Services Task Force have recommended that CT screening is implemented in the USA utilising the NLST criteria, apart from continuing screening to 80 years of age. The cost effectiveness of the NLST was calculated to be $81,000/QALY, however, its well recognised that the costs of medical care in the USA, is far higher than that of Europe. Medicare have agreed to cover the cost of screening but have stipulated a number of stringent requirements for inclusion. To date we do not have good CT screening mortality data available in Europe and eagerly await the publication of the NELSON trial data in 2016 and then the pooled UKLS and NELSON data thereafter. However in the meantime we should start planning for implementation in Europe, especially in the areas of the radiological service provision and accreditation, as well as identifying novel mechanisms to recruit from the hardest to reach communities.

    The objective of this study was to determine the knowledge and associated factors regarding colorectal cancer screening among university students in Malaysia. The questionnaire consisted of three parts: socio-demographic characteristics, lifestyle practice and knowledge of colorectal screening. A cross-sectional study was conducted among 300 students (21.3±1.4 years old). The majority of the participants were Malay with a monthly family income of less than 5,000 Ringgit Malaysia (equal to 1,700 USD) (67.0% and 76.0%, respectively). Regarding their lifestyle practices, the majority were non-smokers and had never consumed alcohol (83.7%, and 88.0%, respectively). The majority of the participants had no knowledge of digital rectal examination, colonoscopy, barium enema and fecal occult blood screening (63.3%, 60.7%, 74.0% and 62.3%, respectively). Univariate and multivariate analysis revealed that their age and the discipline which the students were studying significantly influenced their level of knowledge about colorectal screening. The present study results indicate that education campaigns about colorectal cancer should be promoted. PMID:23679301

    Full Text Available IntroductionIn 2005, the Centers for Disease Control and Prevention funded five sites to implement the Colorectal Cancer Screening Demonstration Program (CRCSDP. An evaluation is being conducted that includes a multiple case study. Case study results for the start-up period, the time between initial funding and screening initiation, provide details about the program models and start-up process and reveal important lessons learned.MethodsThe multiple case study includes all five CRCSDP sites, each representing a unique case. Data were collected from August 2005 through September 2006 from documents, observations, and more than 70 interviews with program staff and stakeholders.ResultsSites differed by geographic service area, screening modality selected, and service delivery structure. Program models were influenced by two factors: preexisting infrastructure and the need to adapt programs to fit local service delivery structures. Several sites modeled program components after their National Breast and Cervical Cancer Early Detection Program. Medical advisory boards convened by all sites provided clinical support for developing program policies and quality assurance plans. Partnerships with comprehensive cancer control programs facilitated access to financial and in-kind resources.ConclusionThe program models developed by the CRCSDP sites offer a range of prototypes. Case study results suggest benefits in employing a multidisciplinary staff team, assembling a medical advisory board, collaborating with local partners, using preexisting resources, designing programs that are easily incorporated into existing service delivery systems, and planning for adequate start-up time.

    AIM: To explore the problems in the screening of colorectal carcinoma in the elderly.METHODS: Three models of colorectal cancer prevention were examined: standard screening, active check-up of suspected cases and summons to have endoscopic checkup for previously diagnosed colorectal polyps. The study was performed among three groups of elderly individuals:Group 1 (167 cases), hospitalized asymptomatic individuals without symptoms in large intestines. Group 2 (612 cases):old individuals at home for the aged, out of which 32 showed symptoms of colon disorders; Group 3 (44 cases): elderly people with diagnosed polyps. As a result of 1788rectosigmoidoscopies, we identified 61 individuals with polyps, out of which 44 patients were over 65 years old.However, only 9 of these 44 individuals agreed to have the endoscopy performed again.RESULTS: One cancer and 13 polyps were detected in Group 1, and two polyps in Group 2. However, it should be noted that only eleven individuals from Group 2 agreed to have the endoscopy. In Group 3, there were no relapses of the polyps among the nine individuals who came back for the endoscopy.CONCLUSION: Poor understanding of the screening procedures is one of the greatest problems in early detection of the cancer in the aged. Paradoxically, the cooperation is better with hospitalized patients, than with "successfully old"persons.

    Full Text Available Objective: Papanicolau (Pap smear abnormalities are more frequently observed in systemic lupus erythematosus (SLE respect to the general population. The primary objective of the present study was to evaluate the adherence to cervical cancer (CC screening in an Italian cohort of SLE patients and, secondly, to evaluate the disease-related factors possibly influencing the patients’ behavior. Methods: Consecutive 25 to 64 year old SLE patients and aged- matched healthy women were enrolled for the study. All patients were interviewed during ambulatory visits, at admission to the clinic or by a telephone contact; disease related variables were also collected from the clinical charts. Results: 140 SLE patients (mean age 48.3±12 years and 70 controls matched for demographic and sociocultural characteristics were enrolled. Ninety-three SLE patients (66.4% declared to perform the Pap test at least every three years (23.6% yearly and 42.8% when asked by the screening programs while 47 (33.6% did not perform regular CC screening (16.4% never did the test and 17.1% only occasionally. No significant differences were observed between patients and controls in cancer screening adherence. No significant associations were observed between the screening program behaviours and disease-related variables. Conclusions: Despite the growing evidence of an increased risk of CC in SLE, and regardless of the broad availability of screening programs and official recommendations, our results show insufficient CC surveillance among SLE patients and emphasize to rheumatologists and/or general practitioners the importance to discuss with patients this aspect during routine evaluations in order to encourage compliance to the recommended preventive measures.

    Breast cancer is the most frequently diagnosed cancer in women. Early detection of breast cancer is known to increase survival rates significantly after diagnosis. This research was carried out to determine the level of breast cancer risk among primary healthcare nurses and their belief in breast cancer screening. In this descriptive research, the data were collected in face-to-face interviews with the participants. The researchers contacted all primary healthcare nurses currently working in the province. The data collection tools included a questionnaire form on sociodemographic characteristics, breast cancer risk assessment form, and Champion's Health Belief Model Scale (CHBMS) for breast cancer screening. In data analysis, descriptive statistics, t test, and analysis of variance (ANOVA) were used. The mean age of nurses was 35 ± 3.6. The mean score for the breast cancer risk assessment form was calculated as 82.9 ± 18.7. The subscale scores for the CHBMS for breast cancer screening were as follows: susceptibility 7.3 ± 1.8, seriousness 19.5 ± 4.1, benefits of breast self-exam 15.5 ± 2.6, barriers to breast self-exam 15.1 ± 2.8, self-efficacy 40.3 ± 7.0, and motivation 19.5 ± 4.1. The risk of breast cancer was found to be low in the study group. The analysis of the subscale scores for the CHBMS for breast cancer screening revealed that nurses had a below-average susceptibility perception, a somewhat lower perception of seriousness, an above-average mean score for perceived benefits, a moderate barrier perception, a relatively high perceived self-efficacy, and motivation above average.

  8. Improved detection of breast cancer on FDG-PET cancer screening using breast positioning device

    International Nuclear Information System (INIS)

    The aim of this study was to investigate the detection rate of breast cancer by positron emission tomography cancer screening using a breast positioning device. Between January 2004 and January 2006, 1,498 healthy asymptomatic individuals underwent cancer screening by fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) at our institution; 660 of 1498 asymptomatic healthy women underwent breast PET imaging in the prone position using the breast positioning device to examine the mammary glands in addition to whole-body PET imaging. All subjects that showed abnormal 18F-FDG uptake in the mammary glands were referred for further examination or surgery at our institution or a local hospital. Our data were compared with the histopathological findings or findings of other imaging modalities in our institution and replies from the doctors at another hospital. Of the 660 participants, 7 (1.06%) were found to have breast cancers at a curable stage. All the seven cancers were detected by breast PET imaging, but only five of these were detected by whole-body PET imaging; the other two were detected by breast PET imaging using the breast positioning device. In cancer screening, prone breast imaging using a positioning device may help to improve the detection rate of breast cancer. However, overall cancer including mammography and ultrasonography screening should be performed to investigate the false-negative cases and reduce false-positive cases. The effectiveness of prone breast PET imaging in cancer screening should be investigated using a much larger number of cases in the near future. (author)

    Full Text Available Cervical cancer is the second most common female cancer worldwide and a disease of concern due to its high rate of incidence of about 500,000 women annually and is responsible for about 280,000 deaths in a year. The mortality and morbidity of cervical cancer are reduced through mass screening via Pap smear, but this technique suffers from very high false negativity of around 30% to 40% and hence the sensitivity of this technique is not more than 60%. Electrical bioimpedance study employing cytosensors over a frequency range offers instantaneous and quantitative means to monitor cellular events and is an upcoming technique in real time to classify cells as normal and abnormal ones. This technology is exploited for label-free detection of diseases by identifying and measuring nonbiological parameters of the cell which may carry the disease signature.

    Full Text Available This paper aimed to assess quality of colonoscopy reports and determine if physicians in practice were already documenting recommended quality indicators, prior to the publication of a standardized Colonoscopy Reporting and Data System (CO-RADS in 2007. We examined 110 colonoscopy reports from 2005-2006 through Maryland Colorectal Cancer Screening Program. We evaluated 25 key data elements recommended by CO-RADS, including procedure indications, risk/comorbidity assessments, procedure technical descriptions, colonoscopy findings, specimen retrieval/pathology. Among 110 reports, 73% documented the bowel preparation quality and 82% documented specific cecal landmarks. For the 177 individual polyps identified, information on size and morphology was documented for 87% and 53%, respectively. Colonoscopy reporting varied considerately in the pre-CO-RADS period. The absence of key data elements may impact the ability to make recommendations for recall intervals. This paper provides baseline data to assess if CO-RADS has an impact on reporting and how best to improve the quality of reporting.

    Full Text Available Changes of glycosylation pattern in serum proteins have been linked to various diseases including cancer, suggesting possible development of novel biomarkers based on the glycomic analysis. In this study, N-linked glycans from human serum were quantitatively profiled by matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF mass spectrometry (MS and compared between healthy controls and ovarian cancer patients. A training set consisting of 40 healthy controls and 40 ovarian cancer cases demonstrated an inverse correlation between P value of ANOVA and area under the curve (AUC of each candidate biomarker peak from MALDI-TOF MS, providing standards for the classification. A multibiomarker panel composed of 15 MALDI-TOF MS peaks resulted in AUC of 0.89, 80~90% sensitivity, and 70~83% specificity in the training set. The performance of the biomarker panel was validated in a separate blind test set composed of 23 healthy controls and 37 ovarian cancer patients, leading to 81~84% sensitivity and 83% specificity with cut-off values determined by the training set. Sensitivity of CA-125, the most widely used ovarian cancer marker, was 74% in the training set and 78% in the test set, respectively. These results indicate that MALDI-TOF MS-mediated serum N-glycan analysis could provide critical information for the screening of ovarian cancer.

    Deciding when to stop cancer screening in older adults is a complex challenge that involves multiple factors: individual health status and life expectancy; risks and benefits of screening, which vary with age and comorbidity; and individual preferences and values. This article examines current cancer screening practices and reviews the risks and benefits of cancer screening for colorectal, breast, lung, prostate, and cervical cancer, particularly in older individuals and those with multiple comorbidities. Tools for estimating life expectancy are reviewed, and a practical framework is presented to guide discussions on when the harms of screening likely outweigh the benefits.

    This review investigated the relative performance of digital breast tomosynthesis (DBT) (alone or with full field digital mammography (FFDM) or synthetic digital mammography) compared with FFDM alone for detecting breast cancer lesions in asymptomatic women. A systematic review was carried out according to systematic reviewing principles provided in the Cochrane Handbook for Systematic Reviews of Diagnostic Test Accuracy. A protocol was developed a priori. The review was registered with PROSPERO (number CRD42014013949). Searches were undertaken in October 2014. Following selection, five studies were eligible. Higher cancer detection rates were observed when comparing DBT + FFDM with FFDM in two European studies: the summary difference per 1000 screens was 2.43 (95% CI: 1.8 to 3.1). Both European studies found lower false positive rates for individual readers. One found a lower recall rate based on conditional recall. The second study was not designed to compare post-arbitration recall rates between FFDM and DBT + FFDM. One European study presented data on interval cancer rates; sensitivity and specificity for DBT + FFDM were both higher compared to FFDM. One large multicentre US study showed a higher cancer detection rate for DBT + FFDM, while two smaller US studies did not find statistically significant differences. Reductions in recall and false positive rates were observed in the US studies in favour of DBT + FFDM. In comparison to FFDM, DBT, as an adjunct to FFDM, has a higher cancer detection rate, increasing the effectiveness of breast cancer screening. Additional benefits of DBT may also include reduced recalls and, consequently, reduced costs and distress caused to women who would have been recalled. PMID:27212700

    INTRODUCTION: Untreated malignant large bowel obstruction is rapidly fatal. Short-term palliation of symptoms can be achieved by formation of a stoma in those patients for whom resection surgery is inappropriate. In the final months of life, a stoma represents a significant burden for both patients and carers. Palliative endoluminal stenting may therefore be an attractive alternative option for this poor prognostic group. PATIENTS: Thirty-six patients were studied of whom 18 had obstructing l...

    Background. Long-term data on breast cancer detection in mammography screening programs are warranted to better understand the mechanisms by which screening changes the breast cancer pattern in the population. We aimed to analyze 17 years of breast cancer detection rates inside and outside...... to women aged 50-69 years. We identified targeted, eligible, invited and participating women. We calculated screening detection and interval cancer rates for participants, and breast cancer incidence in non-screened women (= targeted women excluding participants) by biennial invitation rounds. Tumor...... characteristics were tabulated for each of the three groups of cancers. Results. Start of screening resulted in a prevalence peak in participants, followed by a decrease to a fairly stable detection rate in subsequent invitation rounds. A similar pattern was found for breast cancer incidence in non-screened women...

  2. Hereditary pancreatitis and secondary screening for early pancreatic cancer.

    Hereditary pancreatitis is an autosomal dominant disease with incomplete penetrance (80%), accounting for approximately 1% of all cases of pancreatitis. It is characterized by the onset of recurrent attacks of acute pancreatitis in childhood and frequent progression to chronic pancreatitis. Whitcomb et al. identified the cationic trypsinogen gene (PRSS1) on chromosome 7q35 as the site of the mutation that causes hereditary pancreatitis. The European registry of hereditary pancreatitis and familial pancreatic cancer (EUROPAC) aims to identify and make provisions for those affected by hereditary pancreatitis and familial pancreatic cancer. The most common mutations in hereditary pancreatitis are R122H, N29I and A16V but many families have been described with clinically defined hereditary pancreatitis where there is no PRSS1 mutation. It is known that the cumulative lifetime risk (to age 70 years) of pancreatic cancer is 40% in individuals with hereditary pancreatitis. This subset of individuals form an ideal group for the development of a screening programme aimed at detecting pancreatic cancer at an early stage in an attempt to improve the presently poor long-term survival. Current screening strategies involve multimodality imaging (computed tomography, endoluminal ultrasound) and endoscopic retrograde cholangiopancreatography for pancreatic juice collection followed by molecular analysis of the DNA extracted from the juice. The potential benefit of screening (curative resection) must be balanced against the associated morbidity and mortality of surgery. Philosophically, the individual's best interest must be sought in light of the latest advances in medicine and science following discussions with a multidisciplinary team in specialist pancreatic centres.

For our analysis, we used a dynamic random effects bivariate panel probit model with initial conditions (Wooldridge-type estimator) and dependent variables were the participation of breast and cervical cancer screening in the recent year. The balanced panel sample consisted of 844 women from the British Household Panel Survey (BHPS) from the time period 1992 to 2008. Our analysis showed the high relevance of past screening behaviour and the importance of state dependency for the same and the other type of cancer screening examinations even after controlling for covariates and unobserved heterogeneity. The uptake for breast and cervical cancer screening was higher when the same screening examination was done one or three years earlier. This result is in accordance with the medical screening programmes in Great Britain. With regard to breast and cervical cancer screening positive spillover effects existed between screening examinations in the third order lags. Women with a previous visit to a general practitioner and individuals in the recommended age groups had a higher uptake for breast and cervical cancer screening. Other socioeconomic and health related variables had non-uniform results in both screening examinations. Promoting the uptake of one female prevention activity could also enhance the uptake of the other prevention activity. PMID:26487452

    This research aims to support chest computed tomography (CT) medical checkups to decrease the death rate by lung cancer. We have developed a remote cooperative reading system for lung cancer screening over the Internet, a secure transmission function, and a cooperative reading environment. It is called the Network-based Reading System. A telemedicine system involves many issues, such as network costs and data security if we use it over the Internet, which is an open network. In Japan, broadband access is widespread and its cost is the lowest in the world. We developed our system considering human machine interface and security. It consists of data entry terminals, a database server, a computer aided diagnosis (CAD) system, and some reading terminals. It uses a secure Digital Imaging and Communication in Medicine (DICOM) encrypting method and Public Key Infrastructure (PKI) based secure DICOM image data distribution. We carried out an experimental trial over the Japan Gigabit Network (JGN), which is the testbed for the Japanese next-generation network, and conducted verification experiments of secure screening image distribution, some kinds of data addition, and remote cooperative reading. We found that network bandwidth of about 1.5 Mbps enabled distribution of screening images and cooperative reading and that the encryption and image distribution methods we proposed were applicable to the encryption and distribution of general DICOM images via the Internet.

    Full Text Available Abstract Background Filipino Americans are the fastest growing Asian minority group in the United States. There is limited knowledge about their breast cancer knowledge, screening practices and attitudes. Methods As part of the evaluation of the Asian Grocery Store-Based Cancer Education Program, 248 Filipino American women completed baseline and follow-up surveys, while an additional 58 took part in focus groups. Results Compliance with annual clinical breast exam guidelines among women 40 to 49 years old was 43%, and annual mammography use among women 50 and over was 56%. The Asian Grocery Store-Based Cancer Education Program and complementary focus group study identified multiple barriers that hindered women from attending education programs, with time as the most frequently reported barrier. Conclusion The Asian Grocery Store-Based Cancer Education Program was reported to be a culturally acceptable and effective way of disseminating breast cancer information and one that addressed the women's most frequently reported barrier, lack of time.

    Purpose: To determine whether adding screening ultrasonography to screening mammography can reduce patient recall rates and increase cancer detection rates. Materials and methods: We analyzed the results of mammography and ultrasonography breast screenings performed at the Total Health Evaluation Center Tsukuba, Japan, between April 2011 and March 2012. We also reviewed the modalities and results of diagnostic examinations from women with mammographic abnormalities who visited the Tsukuba Medical Center Hospital for further testing. Results: Of 11,753 women screened, cancer was diagnosed in 10 (0.22%) of the 4529 participants who underwent mammography alone, 23 (0.37%) of the 6250 participants who underwent ultrasonography alone, and 5 (0.51%) of the 974 participants who underwent mammography and ultrasonography. The recall rate due to mammographic abnormalities was 4.9% for women screened only with mammography and 2.6% for those screened with both modalities. The cancer detection rate was 0.22% for women screened only with mammography (positive predictive value, 4.5%) and 0.31% for those screened with both modalities (positive predictive value, 12.0%). Of the 211 lesions presenting as mammographic abnormalities investigated further, diagnostic ultrasonography found no abnormalities in 63 (29.9%) and benign findings in 69 (33.7%). The rest 36.4% needed mammography, cytological or histological examinations or follow-up in addition to diagnostic ultrasonography. Conclusions: It is possible to reduce the recall rate in screening mammography by combining mammography and ultrasonography for breast screening.

    Adoption of clinical decision support has been limited. Important barriers include an emphasis on algorithmic approaches to decision support that do not align well with clinical work flow and human decision strategies, and the expense and challenge of developing, implementing, and refining decision support features in existing electronic health records (EHRs). We applied decision-centered design to create a modular software application to support physicians in managing and tracking colorectal cancer screening. Using decision-centered design facilitates a thorough understanding of cognitive support requirements from an end user perspective as a foundation for design. In this project, we used an iterative design process, including ethnographic observation and cognitive task analysis, to move from an initial design concept to a working modular software application called the Screening & Surveillance App. The beta version is tailored to work with the Veterans Health Administration’s EHR Computerized Patient Record System (CPRS). Primary care providers using the beta version Screening & Surveillance App more accurately answered questions about patients and found relevant information more quickly compared to those using CPRS alone. Primary care providers also reported reduced mental effort and rated the Screening & Surveillance App positively for usability. PMID:26973441

    In France, there is an important interregional disparity concerning participation to cancer screening programs. The aim of this study was to assess oncologic screening practices in Loire, a French rural department, in women and in the elderly (over age 74 years). For this, two surveys were conducted. The first one was regarding screening for breast, cervical and colorectal cancer in women over age 18 years living in Loire. The second survey was regarding onco-geriatric screening through two questionnaires : one for the elderly and the other for general practitioner (GP) of the department, evaluating screening for breast, colorectal, prostate, cervical and lung cancer. One hundred sixty six women were included in the first investigation mean age of 47.6 years. Ninety three point six per cent were screening for breast cancer, 19% received Human Papilloma virus vaccine, 83.1% were screening by Papanicolau smear for cervical cancer and finally, 51.7% were screening for colorectal cancer, among the one entering screening program criteria. In the second survey, 44 patients and 28 GP were included. Thirty-eight point six per cent of patients over 74 years continue screening. Only 11.4% were reluctant to screening and in 80% because of anxiety du to the results. Among GP, 50 % continued screening on two major criteria : life expectancy and performans status. The present study shows heterogeneity of screening in this department both rural and working class and gives us a societo-medical photography.

    In October of 2011, the U.S. Preventive Services Task Force released a draft report in which they recommended against using the prostate-specific antigen (PSA) test to screen for prostate cancer. We attempt to show that four factors documented by psychological research can help explain the furor that followed the release of the task force's report. These factors are the persuasive power of anecdotal (as opposed to statistical) evidence, the influence of personal experience, the improper evaluation of data, and the influence of low base rates on the efficacy of screening tests. We suggest that augmenting statistics with facts boxes or pictographs might help such committees communicate more effectively with the public and with the U.S. Congress. PMID:22555966

    Full Text Available The aim of this qualitative study was to explore the psychological barriers to and facilitators of undergoing the Hemoccult-II® colorectal cancer screening test in France. Sixty-nine French people aged 50 to 74 years were divided into seven qualitative focus groups. Three issues were discussed with participants: knowledge and beliefs about colorectal cancer screening; facilitators of colorectal cancer screening by Hemoccult-II®; barriers to colorectal cancer screening by Hemoccult-II®. All the discussions were led by two psychologists and were recorded, transcribed verbatim and analyzed using qualitative data analysis software. Correspondence factor analyses identified three dimensions for each topic. The main psychological facilitators of colorectal cancer screening were: information about colorectal cancer screening, perceived simplicity of using Hemoccult-II®, and perception of risk. Uncertainty about the reliability of Hemoccult-II®, health anxiety, and embarrassment emerged as the main barriers to colorectal cancer screening. Cross-sectional analyses identified the differences between the views expressed by women and men. Women appeared more embarrassed about Hemoccult-II® and men seemed to be more worried about colorectal cancer. This preliminary study suggests that psychological factors play an important role in colorectal cancer screening by Hemoccult-II®. This finding may help health organizations to conceive better awareness campaigns to promote colorectal cancer screening in order to reduce the related mortality rate by taking into account psychological determinants.

    Full Text Available Objectives. To determine whether persons at high risk of lung cancer would participate in lung cancer screening test if available in Australia and to elicit general attitudes towards cancer screening and factors that might affect participation in a screening program. Methods. We developed a 20-item written questionnaire, based on two published telephone interview scripts, addressing attitudes towards cancer screening, perceived risk of lung cancer, and willingness to be screened for lung cancer and to undertake surgery if lung cancer were detected. The questionnaire was given to 102 current and former smokers attending the respiratory clinic and pulmonary rehabilitation programmes. Results. We gained 90 eligible responses (M:F, 69:21. Mean [SD] age was 63 [11] and smoking history was 32 [21] pack years. 95% of subjects would participate in a lung cancer screening test, and 91% of these would consider surgery if lung cancer was detected. 44% of subjects considered that they were at risk of lung cancer. This was lower in ex-smokers than in current smokers. Conclusions. There is high willingness for lung cancer screening and surgical treatment. There is underrecognition of risk among ex-smokers. This misperception could be a barrier to a successful screening or case-finding programme in Australia.

    Full Text Available BACKGROUND: Cancer surivors have limited knowledge about second primary cancer (SPC screening and suboptimal rates of completion of screening practices for SPC. Our objective was to test the efficacy of an educational material on the knowledge, attitudes, and screening practices for SPC among cancer survivors. METHODS: Randomized, controlled trial among 326 cancer survivors from 6 oncology care outpatient clinics in Korea. Patients were randomized to an intervention or an attention control group. The intervention was a photo-novel, culturally tailored to increase knowledge about SPC screening. Knowledge and attitudes regarding SPC screening were assessed two weeks after the intervention, and screening practices were assessed after one year. RESULTS: At two weeks post-intervention, the average knowledge score was significantly higher in the intervention compared to the control group (0.81 vs. 0.75, P<0.01, with no significant difference in their attitude scores (2.64 vs. 2.57, P = 0.18. After 1 year of follow-up, the completion rate of all appropriate cancer screening was 47.2% in both intervention and control groups. CONCLUSION: While the educational material was effective for increasing knowledge of SPC screening, it did not promote cancer screening practice among cancer survivors. More effective interventions are needed to increase SPC screening rates in this population. TRIAL REGISTRATION: ClinicalTrial.gov NCT00948337.

  5. Stage distribution of breast cancer diagnosed before and after implementation of population-based mammographic screening

    International Nuclear Information System (INIS)

    Purpose: The German mammographic screening program is very similar to the Norwegian Breast Cancer Screening Program (NBCSP), which started about 10 years earlier. This study analyzes the stage distribution of invasive breast cancers diagnosed in the pre-screening and screening period, and evaluates the overall mortality in women aged 55 - 74 in the pilot and non-pilot counties of the NBCSP. Materials and Methods: The NBCSP invites women aged 50 - 69 to participate in two-view mammography biennially. Chi-square statistics were used to compare percentages of the stage and treatment of invasive breast cancers diagnosed in women residing in the four pilot counties in the pre-screening (1984 - 1995) and screening (1996 - 2007) period. An ecological approach was used to analyze the age-specific mortality in the pilot and non-pilot counties for the period 1970 - 2007. Results: 50 % of the breast cancers diagnosed in the pre-screening period, 70 % of the cases detected with screening, 43 % of the interval cancers, and 52 % of the cancers diagnosed outside the NBCSP were stage I. Stage III + was present in 11 % of the cancers in the pre-screening period, and in 1 % of the cancers detected with screening. In the screening period, the breast cancer mortality rate decreased substantially more in the pilot counties than in the non-pilot counties. Conclusion: The stage distribution of breast cancer diagnosed in the NBCSP is prognostically favorable compared to cancers diagnosed outside the screening program. The reduction in the breast cancer mortality rate was more pronounced in the four pilot counties compared to the non-pilot counties. It is necessary to evaluate the program based on individual data.

    Diagnosis of pancreatic cancer (PC) at an early stage with curative surgery should improve long-term patient outcome. At present, improving survival should lie in identifying those cases with high-risk factors or precursor lesions through an effective screening including ultrasonography, some biological markers, or national familial pancreatic cancer registration. Recently, cases with PC detection was higher on endoscopic ultrasonography (EUS) than on CT or other modalities, and EUS-guided fine needle aspiration was helpful in confirming the histologic diagnosis. Additionally, for the diagnosis of cases with PC in situ, EUS and magnetic resonance cholangiopancreatography (MRCP) may play important roles in detecting the local irregular stenosis of the pancreatic duct. Cytodiagnosis of pancreatic juice using endoscopic nasopancreatic drainage multiple times may be useful in the final diagnosis. PMID:26651254

    Full Text Available Cancer screening is a well established and integral part of routine care in the Western world including United States. Men and women are recommended to get age-specific screening for common cancers like breast, cervical, prostate, and colon. The goal of screening is primary and secondary prevention. Cancer prevention and early detection of cancers has been shown to improve survival rates and decrease mortality by prompt appropriate treatment. This article serves to outline the current guidelines in the United States for cancer screening and the evidence for them as well as discusses the possibility of a similar model of care in India as well as barriers to such a screening program for cancer. The evidence was mostly obtained from systematic reviews done by the United States Preventive Services Task Force guidelines and other peer institutions like American Cancer Society and Agency for Healthcare Research and Quality.

    This pictorial review highlights cancers detected only at tomosynthesis screening and screens falsely recalled in the course of breast tomosynthesis screening, illustrating both true-positive (TP) and false-positive (FP) detection attributed to tomosynthesis. Images and descriptive data were used to characterise cases of screen-detection with tomosynthesis, sourced from prospective screening trials that performed standard (2D) digital mammography (DM) and tomosynthesis (3D-mammography) in the same screening participants. Exemplar cases from four trials highlight common themes of relevance to screening practice including: the type of lesions frequently made more conspicuous or perceptible by tomosynthesis (spiculated masses, and architectural distortions); the histologic findings (both TP and FP) of tomosynthesis-only detection; and the need to extend breast work-up protocols (additional imaging including ultrasound and MRI, and tomosynthesis-guided biopsy) if tomosynthesis is adopted for primary screening.

Some neighborhood characteristics--particularly area level socioeconomic factors--have been linked to cancer screening behavior, but few studies have examined the relationship between perceived neighborhood quality and screening behavior, which may provide more insight into the ways in which neighborhood environments shape cancer related behaviors. This study examines the relationship between several aspects of the perceived neighborhood environment and breast and colorectal cancer screening behavior among a population-based sample of Wisconsin residents. A sub-goal was to compare the relevance of different perceived neighborhood factors for different screening tests. This is a cross-sectional study of 2008-2012 data from the Survey of the Health of Wisconsin, a population-based annual survey of Wisconsin residents. An average risk sample of Black, Hispanic and White women age 50 and older (n = 1265) were selected. Survey regression analyses examined predictors of screening, as well as adherence to screening guidelines. Models controlled for individual socio-demographic information and insurance status. Perceptions of social and physical disorder, including fear of crime and visible garbage, were associated with screening rates. Findings emphasize the particular importance of these factors for colorectal cancer screening, indicating the necessity of improving screening rates in areas characterized by social disorganization, crime, and physical disorder. Additional work should be done to further investigate the pathways that explain the linkage between neighborhood conditions, perceived neighborhood risks and cancer screening behavior. PMID:26275881

  12. A comparative study of breast cancer mass screening using ultrasonography and mammography at a single institution

    International Nuclear Information System (INIS)

    In order to evaluate the effectiveness of ultrasonic screening for breast cancer (US group) in comparison with mammographic screening (MMG group), we analyzed 78,214 breast screening examinees presenting between 2007 and 2008 at our institution. The cancer detection rate in the US group was lower than that in the MMG group. However, the average age in the US group was significantly younger than that in the MMG group, and the rate of annual screening was significantly higher in the former than in the latter. In the US subgroup who underwent annual screening, the recall rate and the cancer detection rate were significantly lower, and the rate of detection of early breast cancers was significantly higher than that in the subgroup who underwent screening biennially or at longer intervals, and there was no significant inter-group difference in the cancer detection rate between women in their 40s and those aged 50 or above who underwent annual screening. The proportion of early breast cancers detected was almost the same in the both groups. In summary, US screening as well as MMG screening seems to be useful for detection of early breast cancer. Although a high recall rate for US screening has been reported previously, annual screening and sufficient quality control based on the guidelines proposed by the Japan Association of Breast and Thyroid Sonology (JABTS) are considered to reduce the recall rate.

    2016-01-01

    As the Canadian population continues to age, the incidence of cancer is on the rise. To help alleviate the burden malignancy imposes on our health care system, a shift toward early cancer detection is necessary. Pharmacists are well positioned and willing to assume a more active role in cancer surveillance. Patients are receptive to pharmacist involvement and seem to prefer a convenient community pharmacy–based location for screening programs. The community pharmacist’s current and potential role in cancer screening and prevention is summarized in this article. A review of screening recommendations and a discussion of opportunities will hopefully inspire pharmacists to consider incorporating malignancy screening initiatives into their practice.

    Full Text Available Background: Limited information exists on primary care physicians’ (PCPs use of the prostate-specific antigen (PSA test by patient risk category. We describe PCP responses to hypothetical patient scenario (PS involving PSA testing among high-risk asymptomatic men. Methods: Data were from the 2007 to 2008 National Survey of Primary Care Physicians’ Practices Regarding Prostate Cancer Screening. PS#1: healthy 55-year-old white male with no family history of prostate cancer; PS#2: healthy 45-year-old African American male with no family history of prostate cancer; and PS#3: healthy 50-year-old male with a family history of prostate cancer. Data were analyzed in SAS/SUDAAN. Results: Most PCPs indicated that they generally discuss the possible benefits/risks of PSA testing with the patient and then recommend the test (PS#1-PS#3 range, 53.4%-68.7%; P < .001; only about 1% reported discussing and then recommending against the test. For PS#3, compared to PS#1 and #2, PCPs were more likely to discuss and recommend the test or attempt to persuade the patient who initially declines the test. For PS#3, all clinicians generally would order/discuss the PSA test and not rely on the patient to ask. Conclusion: Clinicians treat family history as an important reason to recommend, persuade, and initiate PSA testing.

    Full Text Available Background: Malawi provides cervical cancer screening services free of charge at some public health facilities. Few women make use of these cancer screening services in Malawi and many women continue to be diagnosed with cervical cancer only during the late inoperable stages of the condition. Objectives: The purpose of this study was to discover whether the perceived susceptibility to cervical cancer, amongst Malawian women aged 42 and older, influenced their intentions to utilise the available free cervical cancer screening services. Method: A quantitative, cross-sectional descriptive study design was adopted. Structured interviews were conducted with 381 women who visited 3 health centres in the Blantyre District of Malawi. Results: A statistically-significant association existed between women’s intentions to be screened for cervical cancer and their knowledge about cervical cancer (X² = 8.9; df = 1; p = 0.003 and with having heard about HPV infection (X² = 4.2; df = 1; p = 0.041 at the 5% significance level. Cervical cancer screening services are provided free of charge in government health institutions in Malawi. Nevertheless, low perceived susceptibility to cervical cancer amongst women, aged 42 and older, might contribute to limited utilisation of cervical screening services, explaining why 80% of cervical cancer patients in Malawi were diagnosed during the late inoperable stages. Conclusion: Malawian women lacked awareness regarding their susceptibility to cervical cancer and required information about the available cervical cancer screening services. Malawi’s women, aged 42 and older, must be informed about the advantages of cervical cancer screening and about the importance of effective treatment if an early diagnosis has been made. Women aged 42 and older rarely attend antenatal, post-natal, well baby or family-planning clinics, where health education about cervical cancer screening is often provided. Consequently, these women

    Full Text Available Abstract Background Professional medical organizations recommend individualized patient decision making about prostate cancer screening. Little is known about primary care physicians' use of pre-screening discussions to promote informed decision making for prostate cancer screening. The aim of this study is to explore physicians' use of pre-screening discussions and reasons why physicians would or would not try to persuade patients to be screened if they initially refuse testing. Methods Primary care physicians completed a self-administered survey about prostate cancer screening practices for informed decision making. Results Sixty-six physicians (75.9% completed the survey, and 63 were used in the analysis. Thirteen physicians (20.6% reported not using prescreening discussions, 45 (71.4% reported the use of prescreening discussions, and 3 (4.8% reported neither ordering the PSA test nor discussing it with patients. Sixty-nine percent of physicians who reported not having discussions indicated they were more likely to screen African American patients for prostate cancer, compared to 50% of physicians who reported the use of discussions (Chi-square(1 = 1.62, p = .20. Similarly, 91% of physicians who reported not having discussions indicated they are more likely to screen patients with a family history of prostate cancer, compared to 46% of those who reported the use of discussion (Chi-square(1 = 13.27, p Conclusion Although guidelines recommend discussing the risks and benefits of prostate cancer screening, physicians report varying practice styles. Future research needs to consider the nature of discussions and the degree to which informed decision making is being achieved in clinical practice.

    Objective: Compare colonic distension and perceived burden of CT-colonography between participants receiving hyoscine butylbromide (buscopan) and glucagon hydrochloride as bowel relaxant. Materials and methods: Data were collected within a screening trial. Participants received 20 mg buscopan intravenously or 1 mg of glucagon intravenously (if buscopan contra-indicated). Colon distension per segment was assessed using a 4-point scale (prone and supine). Data on perceived burden of CT-colonography were collected using a questionnaire two weeks after the examination. Outcome measures between groups were compared using propensity score matching. We used a stratified Wilcoxon-Mann-Whitney test statistic for quantitative and Cochran-Mantel-Haenszel statistics for categorical variables. Results: 541 participants were included: 336 (62%) received buscopan and 205 received glucagon. All buscopan recipients had an adequately distended colon, compared to 96% in the glucagon group (RR 7.31, 95% CI: 1.61-33.28). More glucagon recipients scored the insufflation as rather or extremely burdensome (25% vs. 16%; overall mean score 2.7 vs. 2.4; p < 0.001) and more found the entire CT-colonography rather or extremely burdensome (14% vs. 7%; 2.2 vs. 1.9; p = 0.001). Most frequently reported side effects were a dry mouth in the buscopan group (15%) and nausea in the glucagon group (13%). Conclusion: Compared to glucagon, premedication with buscopan results in significantly more adequately distended colons and a less burdensome procedure. When buscopan can be used, it is the preferred bowel relaxant.

    Full Text Available Abstract Background To explain why rates of colorectal cancer (CRC screening including fecal occult blood testing (FOBT, flexible sigmoidoscopy (FS, colonoscopy (CS, and barium enema (BE, are low, this study assessed determinants of CRC screening from medical records. Methods Data were abstracted from patients aged ≥64 years selected from each clinician from 30 diverse primary care practices (n = 981. Measurements included the rates of annual FOBT, ever receiving FOBT, ever receiving FS/CS/BE under a combination variable, endoscopy/barium enema (EBE. Results Over five years, 8% had received annual FOBT, 53% had ever received FOBT and 22% had ever received EBE. Annual FOBT was negatively associated with female gender, odds ratio (OR = .23; 95% confidence interval = .12–.44 and positively associated with routinely receiving influenza vaccine, OR = 2.55 (1.45–4.47; and more office visits: 3 to Conclusion Overall CRC screening rates were low, but were related to the number of primary care office visits. FOBT was related to immunization status, suggesting the possible benefit of linking these preventive services.

    Screening can reduce incidence and mortality from colorectal cancer but has been underutilized. Efforts to increase screening depend on accurate data about screening status. We sought to evaluate the independent and combined yield of claims and direct survey for identifying colorectal cancer screening among average-risk health plan beneficiaries. Participants were Aetna members ages between 52 and 80 years from 32 primary care practices in Florida and Georgia participating in the Communicating Health Options through Information and Cancer Education study. Main outcomes were the proportion of average-risk patients who were up-to-date with colorectal cancer screening based on claims data and the estimated additional yield of survey data for patients with no evidence of screening in their claims history. Of 4,020 average-risk members identified, claims data indicated that 1,066 (27%) had recent colorectal cancer screening. Among the 1,269 average-risk members with no evidence of screening by claims data who returned surveys, 498 (39%) reported being up-to-date with screening. Combining claims data and survey data and accounting for survey nonresponse, we estimate that 47% to 59% of member patients were actually up-to-date with screening, an additional yield of 20 to 32 percentage points. We conclude that, among health plan members, the combination of claims data and survey information had substantially higher yield than claims data alone for identifying colorectal cancer screening.

  8. A history of breast cancer screening and future problems in Japan

    International Nuclear Information System (INIS)

    In Europe and the United States, mortality due to breast cancer is decreasing. There are various reasons for this trend, including an increase in the detection of early-stage breast cancers due to the increased use of mammographic screening, and the establishment of standardized systemic treatments derived from evidence-based medicine (EBM). On the other hand, in Japanese women, both morbidity and mortality due to breast cancer are increasing. This paper describes the process of breast cancer screening in the past, its current status, and the quality control system for mammographic screening in Japan, as well as the status of breast cancer screening in Europe and the United States. Furthermore, problems of breast cancer screening in Japan discussed, together with the need for practical measures such as implementation of quality control systems aimed at improving the cancer screening rate (with a target of 50%), financial support, and population-based screening (organized screening), based on the Cancer Control Act. Current measures for screening of dense breast tissue in women in their 40s in Japan are also described. (author)

  9. Lung cancer screening: did we really need a randomized controlled trial?

    Science.gov (United States)

    Al-Ayoubi, Adnan M; Flores, Raja M

    2016-07-01

    Lung cancer is the leading cause of cancer mortality in the USA. Within the past decade, two large trials (the National Lung Screening Trial Research and the International Early Lung Cancer Action Program) confirmed a significant role for low-dose CT (LDCT) screening in identifying early stages of cancer leading to reduced mortality in high-risk patients. Given the evidence, the US Preventive Services Task Force issued a recommendation in favour of LDCT screening for high-risk individuals. Despite the strong support for LDCT among physicians who treat lung cancer and cumulative data demonstrating a survival benefit for screening and early detection, it took more than a decade for lung cancer screening to be embraced at the policy level. With many lives lost in the interim, did we really need a randomized controlled trial to make this decision?

    Full Text Available Abstract Background Cancer screening guidelines reflect the costs and benefits of population-based screening based on evidence from clinical trials. While most of the existing literature on compliance with cancer screening guidelines only measures raw screening rates in the target age groups, we used a novel approach to estimate degree of guideline compliance across Canadian provinces for breast, colorectal and prostate cancer screening. Measuring compliance as the change in age-specific screening rates at the guideline-recommended initiation age (50, we generally found screening patterns across Canadian provinces that were not consistent with guideline compliance. Methods We calculated age-cancer-specific screening rates for ages 40-60 using the Canadian Community Health Survey (2003 and 2005, a cross-sectional, nationally representative survey of health status, health care utilization and health determinants in the Canadian population. We estimated the degree of compliance using logistic regression to measure the change in adjusted screening rates at the guideline-recommended initiation age for each province in the sample. Results For breast cancer, after adjusting for age trends and other covariates, being above age 50 in Quebec increased the probability of being screened by 19 percentage points, from an average screening rate of 24% among 40-49 year olds. None of the other regions exhibited a statistically significant change in screening rates at age 50. Additional analyses indicated that these patterns reflect asymptomatic screening and that Quebec's breast cancer screening program enhanced the degree of guideline compliance in that province. Colorectal cancer screening practice was consistent with guidelines only in Saskatchewan, as screening rates increased at age 50 by 12 percentage points, from an average rate of 6% among 40-49 year olds. For prostate cancer, the regions examined here are not compliant with Canadian guidelines since

  13. Radial scars detected mammographically in a breast cancer screening programme

    International Nuclear Information System (INIS)

    Radial scars are getting more and more common since implementation of mammography as diagnostic tool in screening women for breast cancer. At Karolinska Hospital, 18987 asymptomatic women, aged 50-69, were screened for breast cancer through mammography during August 1989-May 1991. A total of 735 (3.87%) were recalled for additional views after initial mammograms and 463 (2.44%) were assessed with help of cytology. In all 175 women (0.92%) were selected for surgery and 146 (0.77%) had histologically verified cancers. The remaining 29 (0.15%) had non- malignant lesions of which 11 (0.06%) were radial scars. All radial scars were diagnosed on mammograms and later confirmed with histology. The radiologic characteristics were found to be a) rather thick and long radiating structures accompanied by radiolucent linear structures parallel to some of the spicules, b) absence of calcifications, c) radiolucent areas in the body of the lesion, d) an average mean size of 6 mm and e) changing image in different views. Most of the lesions, 73% (8/11), were in moderately dense breasts and there was no specific relation to the right or left breast. A majority of radial scars, 64% (7/11), were found in the upper outer quadrants, 3/11 in the lower outer quadrants and 1/11 in the lower inner quadrant. Literature shows that histology uses many synonyms for radial scars and therefore team work between radiologists and pathologists is suggested for better conformity of the diagnosis.

    Full Text Available Abstract Background The advent of prostate specific antigen (PSA testing in the United States of America (USA has led to a dramatic increase in the incidence of prostate cancer in the United States as well as the number of men undergoing aggressive treatment with radical prostatectomy and radiation therapy. We compared patient characteristics and treatment selection between American men with screening-detected versus clinically diagnosed prostate cancers. Methods We evaluated 3,173 men with prostate cancer in the USA. Surveys and medical records provided information on demographics, socioeconomic status, comorbidities, symptoms, tumor characteristics, and treatment. We classified men presenting with symptoms of advanced cancer – bone pain, weight loss, or hematuria – as "clinically diagnosed"; asymptomatic men and those with only lower urinary tract symptoms were considered "screening-detected." We used multivariate analyses to determine whether screening predicted receiving aggressive treatment for a clinically localized cancer. Results We classified 11% of cancers as being clinically diagnosed. Men with screening-detected cancers were more often non-Hispanic white (77% vs. 65%, P Conclusion Most cancers were detected by screening in this American cohort. Appropriately, younger, healthier men were more likely to be diagnosed by screening. Minority status and lower socio-economic status appeared to be screening barriers. Screening detected earlier-stage cancers and was associated with receiving aggressive treatment.

    Background Estimates of radiation-induced breast cancer risk from mammography screening have not previously considered dose exposure variation or diagnostic work-up after abnormal screening. Objective To estimate distributions of radiation-induced breast cancer incidence and mortality from digital mammography screening, considering exposure from screening and diagnostic mammography and dose variation across women. Design Two simulation-modeling approaches using common data on screening mammography from the Breast Cancer Surveillance Consortium and radiation dose from mammography from the Digital Mammographic Imaging Screening Trial. Setting U.S. population. Patients Women aged 40–74 years. Interventions Annual or biennial digital mammography screening from age 40, 45, or 50 until 74. Measurements Lifetime breast cancer deaths averted (benefits) and radiation-induced breast cancer incidence and mortality per 100,000 women screened (harms). Results On average, annual screening of 100,000 women aged 40 to 74 years was projected to induce 125 breast cancers (95% confidence interval [CI]=88–178) leading to 16 deaths (95% CI=11–23) relative to 968 breast cancer deaths averted by early detection from screening. Women exposed at the 95th percentile were projected to develop 246 radiation-induced breast cancers leading to 32 deaths per 100,000 women. Women with large breasts requiring extra views for complete breast examination (8% of population) were projected to have higher radiation-induced breast cancer incidence and mortality (266 cancers, 35 deaths per 100,000 women), compared to women with small or average breasts (113 cancers, 15 deaths per 100,000 women). Biennial screening starting at age 50 reduced risk of radiation-induced cancers 5-fold. Limitations We were unable to estimate years of life lost from radiation-induced breast cancer. Conclusions Radiation-induced breast cancer incidence and mortality from digital mammography screening are impacted by dose

    2016-08-01

    We determined the characteristics and prognosis of interval breast cancers (IC) at screen-film (SFM) and full-field digital (FFDM) screening mammography. The study population consisted of 417,746 consecutive screening mammograms (302,699 SFM screens and 115,047 FFDM screens), obtained between 2000 and 2011. During 2-year follow-up, we collected breast imaging reports, surgical reports, and pathology results. A total of 800 ICs had been diagnosed in the screened population, of which 288 detected in the first year (early ICs) and 512 in the second year (late ICs) after a negative screen. 31.3 % of early IC's and 19.1 % of late IC's, respectively, were visible in retrospect on the latest previous screens, but had been missed during screening (P < 0.001). Missed invasive ICs were larger (28.5 mm vs. 23.9 mm, P = 0.003) and showed a higher fraction of T3+cancers (16.9 vs. 8.5 %, P = 0.02) than true ICs (i.e., not visible at the latest screen). A higher portion of missed than true ICs underwent mastectomy (44.7 vs. 30.8 %, P = 0.002). We found no differences in mammographic and tumor characteristics for early ICs, detected either after SFM or FFDM. Late ICs following FFDM were more often true ICs than missed ICs (69.0 vs. 57.6 %, P = 0.03) and more often receptor triple negative (P = 0.02), compared to late ICs at SFM. Interval cancer subgroups showed comparable overall survival. Interval cancer subgroups show distinctive mammographic and tumor characteristics but a comparable overall survival. PMID:27393617

    The management of patients undergoing colorectal surgery has changed in recent decades. Efforts have been made to show that perioperative physiological stress to the patient can be minimised with standardised care programmes and thus improve short term outcome after colorectal surgery. Mechanical bowel preparation (MBP), for instance, has been questioned as part of standard management. There are studies highlighting the effect of cancer treatment and its side effects in the elderly, showing t...

    Full Text Available Evidence for the clinical utility of human papillomavirus (HPV DNA testing has increased over the years and has now become very convincing. Some specific uses of HPV detection are a triage of women with cytological determinations of atypical squamous cells of undetermined significance (ASC-US and related management strategies, b as a marker for test of cure post-treatment, and c most importantly, as an adjunct to cytology in routine cervical disease screening programs. There are many studies that support each of these applications and include 8 studies on ASC-US triage, 10 on test of cure and 13 on adjunctive or stand-alone HPV screening. The most notable investigation of ASC-US triage was ALTS, a randomized controlled trial of 3 488 women. With respect to routine HPV screening the combined studies included 77 000 women, providing as a histological endpoint more than 1 000 cases of high-grade cervical intraepithelial neoplasia (CIN or cancer. Testing methods were either the Hybrid Capture 2 (HC2 test or the polymerase chain reaction (PCR test. HPV testing of women with ASC-US cytology had on average a higher sensitivity (90% and specificity (70% than repeating the cytological test (sensitivity 75%, specificity 60% and was also more sensitive than colposcopy for follow-up. As an adjunct to the Papanicolaou (Pap cytology test in routine screening, HPV DNA testing was a more sensitive indicator for prevalent high-grade CIN than either conventional or liquid cytology. A combination of HPV DNA and Papanicolaou testing had almost 100% sensitivity and negative predictive value. The specificity of the combined tests was slightly lower than the specificity of the Papanicolaou test. One "double-negative" HPV DNA and Papanicolaou test indicated a higher prognostic assurance against risk of future CIN 3 than three subsequent negative conventional Papanicolaou tests and may safely allow three-year or longer screening intervals for such low- risk women.

  2. Prostate-specific antigen: does the current evidence support its use in prostate cancer screening?

    LENUS (Irish Health Repository)

    Duffy, Michael J

    2012-02-01

    Although widely used, the value of prostate-specific antigen (PSA) in screening asymptomatic men for prostate cancer is controversial. Reasons for the controversy relate to PSA being less than an ideal marker in detecting early prostate cancer, the possibility that screening for prostate cancer may result in the overdetection and thus overtreatment of indolent disease and the lack of clarity as to the definitive or best treatment for men diagnosed with localized prostate cancer. Although the results from some randomized prospective trials suggest that screening with PSA reduces mortality from prostate cancer, the overall benefit was modest. It is thus currently unclear as to whether the modest benefit of reduced mortality outweighs the harms of overdetection and overtreatment. Thus, prior to undergoing screening for prostate cancer, men should be informed of the risks and benefits of early detection. Newly emerging markers that may complement PSA in the early detection of prostate cancer include specific isoforms of PSA and PCA3.

  3. The utility of cancer-related cultural constructs to understand colorectal cancer screening among African Americans

    Full Text Available Background. Data suggest that colorectal cancer could be cut by approximately 60% if all people aged 50 years or older received regular screening. Studies have identified socio-cultural attitudes that might inform cancer education and screening promotion campaigns. This article applies item response theory (IRT to a set of survey items selected to assess sociocultural attitudes in order to determine how current measures may affect what we know about how these attitudes affect colorectal cancer screening (CRCS.Design and Methods. A survey of colorectal cancer screening, screening attitudes and cultural beliefs was administered to 1021 African Americans – 683 women and 338 men, ages 50 to 75. Eligibility crite ria for participation included being born in the United States, self-identified African American male or female, age 50 to 75 years. The IRT analysis was performed on 655 individuals with complete data for the 43 observed variables. Results. Twenty-nine items comprise the Multi-construct African American Cultural Survey (MAACS that addresses seven cultural con- structs: mistrust/distrust, privacy, ethnic identity, collectivism, empowerment, and male gender roles. The items provide adequate information about the attitudes of the population across most levels of the constructs assessed. Among the sociocultural variables considered, empowerment (OR=1.078; 95% CI: 1.008, 1.151 had the strongest association with CRCS adherence and privacy showed promise. Conclusions. The MAACS provides a fixed length questionnaire to assess African American CRCS attitudes, two new constructs that might assist in CRCS promotion, and a suggested focus for identification of additional constructs of interest.

    Full Text Available Abstract Background The aim of the study was to evaluate self-assessed bowel toxicity after radiotherapy (RT for prostate cancer. In contrast to rectal bleeding, information concerning irritative symptoms (rectal urgency, pain and incontinence after RT has not been adequately documented and reported in the past. Methods Patients (n = 286 have been surveyed prospectively before (A, at the last day (70.2-72.0 Gy; B, a median time of two (C and 16 months after RT (D using a validated questionnaire (Expanded Prostate Cancer Index Composite. Bowel domain score changes were analyzed and patient-/dose-volume-related factors tested for a predictive value on three separate factors (subscales: irritative symptoms, incontinence and rectal bleeding. Results Irritative symptoms were most strongly affected in the acute phase, but the scores of all subscales remained slightly lower at time D in comparison to baseline scores. Good correlations (correlation indices >0.4; p Conclusion PTV and specific comorbidities are important predictive factors on adverse bowel quality of life changes after RT for prostate cancer. However, greater rectum volumes inside high isodose levels have not been found to be associated with lower quality of life scores.

  5. Reviewing risks and benefits of low-dose computed tomography screening for lung cancer.

    Lung cancer is the third most common cancer among men and women and is one of the leading causes of cancer-related mortality. Diagnosis at an early stage has been suggested crucial for improving survival in individuals at high-risk of lung cancer. One potential facilitator to early diagnosis is low-dose computed tomography (LDCT). The United States Preventive Services Task Force guidelines call for annual LDCT screening for individuals at high-risk of lung cancer. This recommendation was based on the effectiveness of LDCT in early diagnosis of lung cancer, as indicated by the findings from the National Lung Screening Trial conducted in 2011. Although lung cancer accounts for more than a quarter of all cancer deaths in the United States and LDCT screening shows promising results regarding early lung cancer diagnosis, screening for lung cancer remains controversial. There is uncertainty about risks, cost-effectiveness, adequacy of evidence, and application of screening in a clinical setting. This narrative review provides an overview of risks and benefits of LDCT screening for lung cancer. Further, this review discusses the potential for implementation of LDCT in clinical setting.

    Cervical cancer is becoming a leading cause of death among women in developing countries. Nevertheless, little is known regarding knowledge and perception of cervical cancer and screening behaviour particularly among female tertiary students in Ghana. This study sought to examine the knowledge and perceptions of cervical cancer and screening behaviour among female students in the University of Cape Coast and Ghana Institute of Management and Public Administration in Ghana. A cross-sectional survey design was adopted for the study. Systematic and stratified random sampling techniques were used to select 410 participants for the study. The study found that the participants lacked knowledge on specific risk factors and symptoms of cervical cancer. Also, even though the participants had a fair perception of cervical cancer, they had a poor cervical cancer screening behaviour. Awareness of cervical cancer was significantly influenced by religious affiliation while cervical cancer screening was significantly determined by the working status of the participants. Specific knowledge on cervical cancer and its risk factors as well as regular screening behaviour is paramount to the prevention of cervical cancer. Consequently, the University Health Services should focus on promoting regular cervical cancer awareness campaigns and screening among the students particularly, females. PMID:25957285

    Lung cancer screening identifies cancers with heterogeneous behaviors. Some lung cancers will be identified among patients who had prior negative CT screens and upon follow-up scans develop a de novo nodule that was determined to be cancerous. Other lung cancers will be identified among patients who had one or more prior stable positive scans that were not determined to be lung cancer (indeterminate pulmonary nodules), but in follow-up scans was diagnosed with an incidence lung cancer. Using data from the CT arm of the National Lung Screening Trial, this analysis investigated differences in patient characteristics and survival endpoints between prevalence-, interval-, and screen-detected lung cancers, characterized based on sequence of screening results. Lung cancers immediately following a positive baseline (T0), and prior to the T1 screen, formed the prevalence cohort. Interval cancers were diagnosed following a negative screen at any time point prior to the next screening round. Two cohorts of screen-detected lung cancers (SDLC) were identified that had a baseline positive screen that was that was not determined to be lung cancer (i.e., an indeterminate pulmonary nodule), but in follow-up scans was diagnosed with an incidence lung cancer 12 (SDLC1) or 24 (SDLC2) months later. Two other incidence cohorts had screen-detected lung cancers that had baseline negative screen and upon follow-up scans developed a de novo nodule determined to be cancerous at 12 (SDLC3) or 24 (SDLC4) months later. Differences in patient characteristics, progression-free survival (PFS), and overall survival (OS) were assessed. The lung cancer-specific death rate was higher for SDLC3/SDLC4 compared to SDLC1/SDLC2 lung cancers (136.6/1,000 person-years vs. 71.3/1,000 person-years, P lung cancers (HR = 1.00). Lung cancer patients who develop a de novo nodule that determined to be cancerous (i.e., at least one negative CT screen prior to cancer diagnosis) had poorer survival outcomes compared
