    Breast cancer is the most frequent malignant tumor in women worldwide. In Egypt, it is the most common cancer among women, representing 18.9% of total cancer cases (35.1% in women and 2.2% in men) among the Egypt National Cancer Institute's (NCI) series of 10,556 patients during the year 2001, with an age-adjusted rate of 49.6 per 100,000 people. In this study, the data of all breast cancer patients presented to the surgical department of the South Egypt cancer Institute (SECI) hospital during the period from Janurary 2001 to December 2008 were reviewed .We report the progress of the availability of breast cancer management and evaluation of the quality of care delivered to breast cancer patients. The total number of patients with a breast lump presented to the SECI during the study period was 1,463 patients (32 males and 1431 females); 616 patients from the total number were admitted at the surgical department .There was a decline in advanced cases. Since 2001, facilities for all lines of comprehensive management have been made accessible for all patients. We found that better management could lead to earlier presentation, and better overall outcome in breast cancer patients.The incidence is steadily increasing with a tendency for breast cancer to occur in younger age groups and with advanced stages.

    Breast cancer is a leading cancer diagnosis among premenopausal women around the world. Unlike rates in postmenopausal women, incidence rates of advanced breast cancer have increased in recent decades for premenopausal women. Progress in identifying contributors to breast cancer risk among premenopausal women has been constrained by the limited numbers of premenopausal breast cancer cases in individual studies and resulting low statistical power to subcategorize exposures or to study specific subtypes. The Premenopausal Breast Cancer Collaborative Group was established to facilitate cohort-based analyses of risk factors for premenopausal breast cancer by pooling individual-level data from studies participating in the United States National Cancer Institute Cohort Consortium. This paper describes the Group, including the rationale for its initial aims related to pregnancy, obesity, and physical activity. We also describe the 20 cohort studies with data submitted to the Group by June 2016. The infrastructure developed for this work can be leveraged to support additional investigations. PMID:28600297

    Background: Male breast cancer incidence rises with age with peak in the sixth and seventh decade. It is one of the rare diseases and accounts for less than 1% of all malignancies worldwide. It is usually diagnosed in the late stage with poor prognosis. Objective: The purpose of this study was to know the demographic pattern and tumour characteristic of breast cancer in men reported at Institute of Radiotherapy and Nuclear Medicine (IRNUM), Peshawar. Methods: Retrospective data was collected from the (IRNUM), Peshawar for a period of three years (2006-2008). The evaluation was done from the histopathological reports of mastectomy and biopsy specimens. All male patients in the age group 26 -86 year with breast cancer were included in the study. The age of the patients and tumour characteristics recorded were size, grade, type, skin involvement and stage. Results: Total number of male patients with breast cancer were 31 (2.1%) out of the total patients with breast malignancy during the study period with the mean age of 58.3 years. Tumour size ranged from 2 to 12 Cm. with average of 3.6 Cm. Invasive ductal carcinoma was found in 87% , papillary carcinoma in 6.5%, each of malignant fibrous histocytoma and sarcoma in 3.2% cases. Maximum number of patients was of grade II (41%). Patients in whom stage of the disease was know n were 22 cases with 45.5% had stage III disease and 32% had stage IV disease. Skin involvement was found positive in 8 (25.8%). Conclusion: Due to poor health care system breast cancer is diagnosed in a late stage of the disease and prognosis is poor. (author)

    It has been long recognized that Thyroid Cancer (TC) envelopes under its umbrella a spectrum of cancers from the relatively indolent well differentiated papillary and follicular cancers to the aggressive and rapidly fatal anaplastic cancers. Medullary cancers fall in between the two extremes. Recently, poor prognostic variants of well-differentiated cancers have been described. There is also a move to define a group of poorly differentiated TC including the insular variants distinguishing them from anaplastic carcinomas. Of the 1168 patients with thyroid nodules seen at the Cancer Institute (WIA), Chennai between 1956 and 1996, 670 cases proved to be malignant either cytologically or histologically. This report is based on the follow-up of these patients which at 10 years was 75%

    Retrospective studies on oral cancer patient profiles related to risk habits could provide etiologic clues for prevention in specific geographic areas. To study risk habit characteristics of oral cancer patients. A cross sectional retrospective case record study of oral cancer patients who reported during 1991-2000 to Karnataka Cancer Therapy and Research Institute, Hubli, India was conducted. Data on socio-demography, histopathology, site of cancer and risk habit profiles of the patients were recorded in a predesigned Performa by one calibrated examiner with internal validity checks. The 1,472 oral cancer patients constituted 11% of total cancer patients. Mean age of the patients was 55 years, ranging from 12-88, with a male: female ratio of 2:1. 1,110 (75%) oral cancer patients had risk habits, 55% were habituated for >10 years and 25% were habit free. 751(51%) patients had individual and 359(24%) had combined risk habits. Majority 59% were chewers of betel quid alone (17%)/betel quid with tobacco (42%); smokers were (31%) and alcohol users were (14%) of patients. Chewers of gutkha, khaini were more in 40 years. Risk habituates were highest (87%) in patients with cancer of buccal mucosa, commonly affected site attributed to chewing habit in (51%) of patients. The prevalence of oral cancer was higher among elderly males predominantly with risk habits of betel quid/tobacco chewing and smoking for more than 10 years.

    The accreditation process is, on the one hand, a tool used to homogenize procedures, rendering comparable and standardized processes of care, and on the other, a methodology employed to develop a culture of quality improvement. Although not yet proven by evidence-based studies that health outcomes improve as a result of an accreditation to excellence, it is undeniable that better control of healthcare processes results in better quality and safety of diagnostic and therapeutic pathways. The Regina Elena National Cancer Institute underwent the accreditation process in accordance with the standards criteria set by the Organisation of European Cancer Institutes (OECI), and it has recently completed the process, acquiring its designation as a Comprehensive Cancer Center (CCC). This was an invaluable opportunity for the Regina Elena Institute to create a more cohesive environment, to widely establish a culture of quality, to implement an institutional information system, and to accelerate the process of patient involvement in strategic decisions. The steps of the process allowed us to evaluate the performance and the organization of the institute and put amendments in place designed to be adopted through 26 improvement actions. These actions regarded several aspects of the institute, including quality culture, information communication technology system, care, clinical trials unit, disease management team, nursing, and patient empowerment and involvement. Each area has a timeline. We chose to present the following 3 improvement actions: clinical trial center, computerized ambulatory medical record, and centrality of patient and humanization of clinical pathway.

    In 1961, the USA severed diplomatic relations with Cuba, and in 1962 an embargo was imposed on trade and financial relations with that country. It was not until five decades later that the USA and Cuba would reestablish relations. This opened the way for the New York State Trade Mission to Cuba in April 2015, during which Cuba's Molecular Immunology Center and Buffalo, New York's Roswell Park Cancer Institute signed a formal agreement that would set in motion biotechnology research collaboration to address one of the most important causes of death in both countries. Significant research from Cuba led to this groundbreaking collaboration. The purpose of this paper is to discuss the development of this cooperation, from the Molecular Immunology Center's initial investigations, through the opening of a phase I clinical trial at Roswell Park Cancer Institute with therapies developed at the Center. This cooperation was responsible for the first clinical trial for CIMAvax-EGF involving advanced-stage non-small cell lung cancer patients in the USA. A license was also approved by the US Department of the Treasury's Office of Foreign Assets Control authorizing a commercial partnership for development of biotechnology products, combining the cancer research efforts of both institutions. This unusual collaboration between Cuba and the USA-the US economic embargo and travel restrictions not withstanding-opens good prospects for expanded medical research between the two countries. While political and logistical challenges remain, the shared mission and dedication of these Cuban and US scientists points the way towards relationships that can lead to development, testing, approval and use of promising new therapies for cancer patients.

  2. Northeast Regional Cancer Institute's Cancer Surveillance and Risk Factor Program

    Energy Technology Data Exchange (ETDEWEB)

    Lesko, Samuel M.

    2007-07-31

    OBJECTIVES The Northeast Regional Cancer Institute is conducting a program of ongoing epidemiologic research to address cancer disparities in northeast Pennsylvania. Of particular concern are disparities in the incidence of, stage at diagnosis, and mortality from colorectal cancer. In northeast Pennsylvania, age-adjusted incidence and mortality rates for colorectal cancer are higher, and a significantly smaller proportion of new colorectal cancer cases are diagnosed with local stage disease than is observed in comparable national data. Further, estimates of the prevalence of colorectal cancer screening in northeast Pennsylvania are lower than the US average. The Northeast Regional Cancer Institute’s research program supports surveillance of common cancers, investigations of cancer risk factors and screening behaviors, and the development of resources to further cancer research in this community. This project has the following specific objectives: I. To conduct cancer surveillance in northeast Pennsylvania. a. To monitor incidence and mortality for all common cancers, and colorectal cancer, in particular, and b. To document changes in the stage at diagnosis of colorectal cancer in this high-risk, underserved community. II. To conduct a population-based study of cancer risk factors and screening behavior in a six county region of northeast Pennsylvania. a. To monitor and document changes in colorectal cancer screening rates, and b. To document the prevalence of cancer risk factors (especially factors that increase the risk of colorectal cancer) and to identify those risk factors that are unusually common in this community. APPROACH Cancer surveillance was conducted using data from the Northeast Regional Cancer Institute’s population-based Regional Cancer Registry, the Pennsylvania Cancer Registry, and NCI’s SEER program. For common cancers, incidence and mortality were examined by county within the region and compared to data for similar populations in the US

    Colorectal cancer (CRC) has the second highest cancer mortality rate in Australia. The Australian National Bowel Cancer Screening Program (NBCSP) aims to increase early detection of CRC by offering free Faecal Occult Blood Testing (FOBT), although uptake is low for culturally and linguistically diverse (CALD) groups. To present data on trust and mistrust in the NBCSP by population groups with low uptake and thus to highlight areas in need of policy change. A qualitative study was undertaken in South Australia, involving interviews with 94 people from four CALD groups: Greek, Iranian, Anglo-Australian, and Indigenous peoples. Our study highlights the complexities of institutional trust, which involves considerations of trust at interpersonal, local and national levels. In addition, trust and mistrust was found in more abstract systems such as the medical knowledge of doctors to diagnose or treat cancer or the scientific procedures in laboratories to test the FOBTs. The object of institutional (mis)trust differed between cultural groups - Anglo-Australian and Iranian groups indicated a high level of trust in the government, whereas Indigenous participants were much less trusting. The level and nature of trust in the screening process varied between the CALD groups. Addressing program misconceptions, clarifying the FOBT capabilities and involving medical services in collecting and transporting the samples may increase trust in the NBCSP. However, broader and more enduring mistrust in services and institutions may need to be dealt with in order to increase trust and participation. © 2014 John Wiley & Sons Ltd.

    Full Text Available Abstract The development and maintenance of adequate shared infrastructures is considered a major goal for academic centers promoting translational research programs. Among infrastructures favoring translational research, centralized facilities characterized by shared, multidisciplinary use of expensive laboratory instrumentation, or by complex computer hardware and software and/or by high professional skills are necessary to maintain or improve institutional scientific competitiveness. The success or failure of a shared resource program also depends on the choice of appropriate institutional policies and requires an effective institutional governance regarding decisions on staffing, existence and composition of advisory committees, policies and of defined mechanisms of reporting, budgeting and financial support of each resource. Shared Resources represent a widely diffused model to sustain cancer research; in fact, web sites from an impressive number of research Institutes and Universities in the U.S. contain pages dedicated to the SR that have been established in each Center, making a complete view of the situation impossible. However, a nation-wide overview of how Cancer Centers develop SR programs is available on the web site for NCI-designated Cancer Centers in the U.S., while in Europe, information is available for individual Cancer centers. This article will briefly summarize the institutional policies, the organizational needs, the characteristics, scientific aims, and future developments of SRs necessary to develop effective translational research programs in oncology. In fact, the physical build-up of SRs per se is not sufficient for the successful translation of biomedical research. Appropriate policies to improve the academic culture in collaboration, the availability of educational programs for translational investigators, the existence of administrative facilitations for translational research and an efficient organization

    Purpose To evaluate interradiologist agreement on assessments of computed tomography (CT) imaging features of high-grade serous ovarian cancer (HGSOC), to assess their associations with time-to-disease progression (TTP) and HGSOC transcriptomic profiles (Classification of Ovarian Cancer [CLOVAR]), and to develop an imaging-based risk score system to predict TTP and CLOVAR profiles. Materials and Methods This study was a multireader, multi-institutional, institutional review board-approved, HIPAA-compliant retrospective analysis of 92 patients with HGSOC (median age, 61 years) with abdominopelvic CT before primary cytoreductive surgery available through the Cancer Imaging Archive. Eight radiologists from the Cancer Genome Atlas Ovarian Cancer Imaging Research Group developed and independently recorded the following CT features: characteristics of primary ovarian mass(es), presence of definable mesenteric implants and infiltration, presence of other implants, presence and distribution of peritoneal spread, presence and size of pleural effusions and ascites, lymphadenopathy, and distant metastases. Interobserver agreement for CT features was assessed, as were univariate and multivariate associations with TTP and CLOVAR mesenchymal profile (worst prognosis). Results Interobserver agreement for some features was strong (eg, α = .78 for pleural effusion and ascites) but was lower for others (eg, α = .08 for intraparenchymal splenic metastases). Presence of peritoneal disease in the right upper quadrant (P = .0003), supradiaphragmatic lymphadenopathy (P = .0004), more peritoneal disease sites (P = .0006), and nonvisualization of a discrete ovarian mass (P = .0037) were associated with shorter TTP. More peritoneal disease sites (P = .0025) and presence of pouch of Douglas implants (P = .0045) were associated with CLOVAR mesenchymal profile. Combinations of imaging features contained predictive signal for TTP (concordance index = 0.658; P = .0006) and CLOVAR profile (mean

    To evaluate the quality assurance of mammography results at a reference institution for the diagnosis and treatment of breast cancer in southern Brazil, based on the BIRADS (Breast Imaging Reporting and Data System) 5th edition recommendations for auditing purposes. Retrospective cohort and cross-sectional study with 4502 patients (9668 mammographies)) who underwent at least one or both breast mammographies throughout 2013 at a regional public hospital, linked to a federal public university. The results were followed until 31 December 2014, including true positives (TPs), true negatives (TNs), false positives (FPs), false negatives (FNs), positive predictive values (PPVs), negative predictive value (NPV), sensitivity and specificity, with a confidence interval of 95%. The study showed high quality assurance, particularly regarding sensitivity (90.22%) and specificity (92.31%). The overall positive predictive value (PPV) was 65.35%, and the negative predictive value (NPV) was 98.32%. The abnormal interpretation rate (recall rate) was 12.26%. The results are appropriate when compared to the values proposed by the BIRADS 5th edition. Additionally, the study provided self-reflection considering our radiological practice, which is essential for improvements and collaboration regarding breast cancer detection. It may stimulate better radiological practice performance and continuing education, despite possible infrastructure and facility limitations. • Accurate quality performance rates are possible despite financial and governmental limitations. • Low-income institutions should develop standardised teamwork to improve radiological practice. • Regular mammography audits may help to increase the quality of public health systems.

  14. The flat‐funding years and the National Cancer Institute: Consequences for cancer research

    OpenAIRE

    2008-01-01

    The National Cancer Institute (NCI), the principal federal agency for cancer research and training in the US, has contended with a flat budget since 2004, which according to the institute's director is preventing the organisation from keeping pace with the increasing costs of biomedical research. Although the impact of these budget shortfalls are still being debated, Niederhuber believes these so‐called “flat‐funding years” may pave the way for worrying future trends, resulting in a paucity o...

    Full Text Available Introduction: Use of Complementary and alternative medicine (CAM is high among cancer patients especially breast cancer patients. This study sought to evaluate Complementary and alternative medicine use in breast cancer patients and how its use is influencedby patient’s satisfaction with conventional medical treatment among breast cancer patients attending Uganda Cancer Institute. Patients and Methods: A cross-sectional study design was used in this study. Participants who were diagnosed histologically with breast cancer at Uganda Cancer Institute took part in the study. A questionnaire was developed and used to interview the participants and medical records of the respondents were also reviewed. Results: A total of 235 participants completed the study. The prevalence of CAM use was 77%. CAM therapies used included herbal medicines, prayer for health, vitamins/minerals, native healers, Chinese medicines, massage, yoga, Ayurvedic medicine, Acupuncture, reflexolog, Support group attendance, meditation, Magnetic and Bio-fieldmanipulation. Satisfaction with medical treatment was significantlyassociated with CAM use. Patients who are not satisfiedwith medical treatment were more likely to use CAM. Conclusion: There is a high number of breast cancer patients using CAM, various categories of therapies are being used and patients’ satisfaction with medical treatment triggers off a patients decision to use CAM therapies.

    Identification of patients at risk of hereditary cancer is an essential component of oncology practice, since it enables clinicians to offer early detection and prevention programs. However, the large number of hereditary syndromes makes it difficult to take them all into account in daily practice. Consequently, the National Cancer Institute (NCI) has suggested a series of criteria to guide initial suspicion. It was the aim of this study to assess the perception of the risk of hereditary cancer according to the NCI criteria in our medical oncology service. We retrospectively analyzed the recordings of the family history in new cancer patients seen in our medical oncology service from January to November 2009, only 1 year before the implementation of our multidisciplinary hereditary cancer program. The family history was recorded in only 175/621 (28%) patients. A total of 119 (19%) patients met 1 or more NCI criteria (1 criterion, n = 91; 2 criteria, n = 23; 3 criteria, n = 4; and 4 criteria, n = 1), and only 14 (11.4%) patients were referred to genetic counseling. This study shows that few clinicians record the family history. The perception of the risk of hereditary cancer is low according to the NCI criteria in our medical oncology service. These findings can be explained by the lack of a multidisciplinary hereditary cancer program when the study was performed. Copyright © 2012 S. Karger AG, Basel.

    The National Institutes of Health (NIH) issued a new policy that requires a single institutional review board (IRB) of record be used for all protocols funded by the NIH that are carried out at more than one site in the United States, effective January 2018. This policy affects several hundred clinical trials opened annually across the NIH. Limited data exist to compare the use of a single IRB to that of multiple local IRBs, so some institutions are resistant to or distrustful of single IRBs. Since 2001, the National Cancer Institute (NCI) has funded a central IRB (CIRB) that provides human patient reviews for its extensive national cancer clinical trials program. This paper presents data to show the adoption, efficiencies gained, and satisfaction of the CIRB among NCI trial networks and reviews key lessons gleaned from 16 years of experience that may be informative for others charged with implementation of the new NIH single-IRB policy.

    Full Text Available Penile cancer is an uncommon malignancy. Surgical treatment is inevitably mutilating. Considering the strong impact on patients′ sexual life we want to evaluate sexual function and satisfaction after partial penectomy. The patients in this study (n = 25 represented all those who attended our institutions and were diagnosed and treated for penile cancer from October 2011 to November 2013. All patients underwent partial penectomy and followed-up (mean: 14 months; range: 12-25. Sexual presurgical baseline was estimated using the International Index of Erectile Dysfunction 15 (IIEF-15. Sexual outcomes of each patient were estimated considering four standardized and validated questionnaires. We analyzed the means and ranges of IIEF-15 including erectile function (IIEF-1-5 and -15, orgasmic function (IIEF-9 and -10, sexual desire (IIEF-11 and -12, intercourse satisfaction (IIEF-6-8, and overall satisfaction (IIEF-13 and -14. Then, we also used Quality of Erection Questionnaire (QEQ, Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS and Self-Esteem and Relationship (SEAR to evaluate the sexual function and satisfaction of our patients. The final results showed that penile cancer leads to several sexual and psychosexual dysfunctions. Nevertheless, patients who undergo partial penectomy for penile cancer can maintain the sexual outcomes at levels slightly lower to those that existed in the period before surgery.

    The value of community-based cancer research has long been recognized. In addition to the National Cancer Institute's Community Clinical and Minority-Based Oncology Programs established in 1983, and 1991 respectively, the National Cancer Institute established the National Cancer Institute Community Cancer Centers Program in 2007 with an aim of enhancing access to high-quality cancer care and clinical research in the community setting where most cancer patients receive their treatment. This article discusses strategies utilized by the National Cancer Institute Community Cancer Centers Program to build research capacity and create a more entrenched culture of research at the community hospitals participating in the program over a 7-year period. To facilitate development of a research culture at the community hospitals, the National Cancer Institute Community Cancer Centers Program required leadership or chief executive officer engagement; utilized a collaborative learning structure where best practices, successes, and challenges could be shared; promoted site-to-site mentoring to foster faster learning within and between sites; required research program assessments that spanned clinical trial portfolio, accrual barriers, and outreach; increased identification and use of metrics; and, finally, encouraged research team engagement across hospital departments (navigation, multidisciplinary care, pathology, and disparities) to replace the traditionally siloed approach to clinical trials. The health-care environment is rapidly changing while complexity in research increases. Successful research efforts are impacted by numerous factors (e.g. institutional review board reviews, physician interest, and trial availability). The National Cancer Institute Community Cancer Centers Program sites, as program participants, had access to the required resources and support to develop and implement the strategies described. Metrics are an important component yet often challenging to

    We investigated the association between adherence to the recommendations of the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) and breast cancer (BC) risk in the Cancer de Màma (CAMA) study in a Mexican population. Population-based case-control study. Incident BC cases (n 1000) and controls (n 1074) matched on age, region and health-care system were recruited. In-person interviews were conducted to assess BC risk factors and habitual diet was assessed with an FFQ. Conformity to the WCRF/AICR recommendations was evaluated through a score incorporating seven WCRF/AICR components (body fatness, physical activity, foods and drinks that promote weight gain, plant foods, animal foods, alcoholic drinks and breast-feeding), with high scores indicating adherence to the WCRF/AICR recommendations. No statistically significant associations between WCRF/AICR score and risk of BC were observed. After excluding BMI from the WCRF/AICR score, the top quartile was associated with a decreased BC risk overall, with ORQ4-Q1=0.68 (95% CI 0.49, 0.92, P trend=0.03), and among postmenopausal women, with ORQ4-Q1=0.60 (95% CI 0.39, 0.94, P trend=0.03). Inverse associations were observed between BMI and risk of BC overall and among premenopausal women, with OR=0.57 (95% CI 0.42, 0.76, P trend <0.01) and 0.48 (95% CI 0.31, 0.73, P trend<0.01), respectively. Physical activity level was inversely associated with BC risk. The WCRF/AICR index was not related with BC risk in the CAMA study. A combination of six components excluding BMI showed strong protective associations, particularly in postmenopausal women. Further prospective studies are required to clarify the role of adherence to WCRF/AICR recommendations, particularly with respect to BMI, in the Mexican population.

    Data from seven studies sponsored by the National Cancer Institute (NCI) were used to determine current rates of breast cancer screening and to identify the characteristics of and reasons for women not being screened. All seven studies were population-based surveys of women aged 50 to 74 years without breast cancer. While over 90% of non-Hispanic white respondents had regular sources of medical care, 46% to 76% had a clinical breast examination within the previous year, and only 25% to 41% had a mammogram. Less educated and poorer women had fewer mammograms. The two most common reasons women gave for never having had a mammogram were that they did not known they needed it and that their physician had not recommended it. Many physicians may have overlooked the opportunity to recommend mammography for older women when performing a clinical breast examination and to educate their patients about the benefit of screening mammography

    To evaluate in a multi-institutional study whether radiomic features useful for prostate cancer (PCa) detection from 3 Tesla (T) multi-parametric MRI (mpMRI) in the transition zone (TZ) differ from those in the peripheral zone (PZ). 3T mpMRI, including T2-weighted (T2w), apparent diffusion coefficient (ADC) maps, and dynamic contrast-enhanced MRI (DCE-MRI), were retrospectively obtained from 80 patients at three institutions. This study was approved by the institutional review board of each participating institution. First-order statistical, co-occurrence, and wavelet features were extracted from T2w MRI and ADC maps, and contrast kinetic features were extracted from DCE-MRI. Feature selection was performed to identify 10 features for PCa detection in the TZ and PZ, respectively. Two logistic regression classifiers used these features to detect PCa and were evaluated by area under the receiver-operating characteristic curve (AUC). Classifier performance was compared with a zone-ignorant classifier. Radiomic features that were identified as useful for PCa detection differed between TZ and PZ. When classification was performed on a per-voxel basis, a PZ-specific classifier detected PZ tumors on an independent test set with significantly higher accuracy (AUC = 0.61-0.71) than a zone-ignorant classifier trained to detect cancer throughout the entire prostate (P  0.14) were obtained for all institutions. A zone-aware classifier significantly improves the accuracy of cancer detection in the PZ. 3 Technical Efficacy: Stage 2 J. MAGN. RESON.

    2017-11-11

    The National Cancer Institute (NCI) Cancer Centers form the backbone of the cancer care system in the United States since their inception in the early 1970s. Most studies on their geographic accessibility used primitive measures, and did not examine the disparities across urbanicity or demographic groups. This research uses an advanced accessibility method, termed "2-step floating catchment area (2SFCA)" and implemented in Geographic Information Systems (GIS), to capture the degree of geographic access to NCI Cancer Centers by accounting for competition intensity for the services and travel time between residents and the facilities. The results indicate that urban advantage is pronounced as the average accessibility is highest in large central metro areas, declines to large fringe metro, medium metro, small metro, micropolitan and noncore rural areas. Population under the poverty line are disproportionally concentrated in lower accessibility areas. However, on average Non-Hispanic White have the lowest geographic accessibility, followed by Hispanic, Non-Hispanic Black and Asian, and the differences are statistically significant. The "reversed racial disadvantage" in NCI Cancer Center accessibility seems counterintuitive but is consistent with an influential prior study; and it is in contrast to the common observation of co-location of concentration of minority groups and people under the poverty line.

    2010-01-01

    Purpose: To assess the survival rate of female lung cancer treated at the Institute of Oncology of the Vilnius University, Lithuania during the period between 1996-2005. Materials and Methods: During the period between 1996-2005, 471 women diagnosed with lung cancer were treated at the Department of Thoracic Surgery and Oncology of the Institute of Oncology, Vilnius University. Data on morphology, stage and treatment was collected from the medical records. All lung cancer cases by histology were classified in two groups: non-small cell lung cancer (includes squamous cell carcinoma, large cell carcinoma, adenocarcinoma and other less common types) and small cell lung cancer. The vital status of the study group was assessed as of December 31, 2007, by passive follow-up, using data from the population registry. It was found that 411 (87.3%) of the patients had died. Survival was estimated according to the Kaplan-Meier method. Results: The median survival of female lung cancer diagnosed during 1996-2005 in Lithuania show to be 8.7 months (8.4 (95% CI 7.2-10.8) months with non-small cell lung cancer and 9.3 (95% CI 6.3-13.0) months with small-cell lung cancer). Survival was more than 20 months in resectable non-small cell lung cancer (stages I, II, IIIA). Non-small cell lung cancer survival in advanced stages was less than 7 months. Small-cell lung cancer patients median survival at limited and extended stages of the disease were 9.5 (95% CI 2.9-18.4) compared to 9.2 (95% CI 6.2-13.7) months. Non-small cell lung cancer patients most frequently were treated by surgery (27.0%), surgery and chemotherapy or radiotherapy (19.6%). Small cell lung cancer patient treatment included chemo and radiotherapy (27.0%), chemotherapy (19.0%), radiotherapy (17.5%), surgery (27.9%). Conclusions: The single center study of female lung cancer diagnosed during 1996-2005 in Lithuania show a significantly better chance of survival in resectable non-small cell lung cancer.

    2017-02-01

    The goal of this study was to elucidate the attitudes, beliefs, and barriers interfering with cancer pain management, the degree of barrier interference with trainees’ care of patients, and the relationships among prohibitive factors to pain management for physicians in a low–middle-income countries (LMICs) vs high-income countries (HICs). A multi-institutional cross-sectional survey of physicians in specialties with a focus in pain management training was performed. All surveys were completed anonymously from July 1, 2015, to November 30, 2015. One hundred and twenty physicians participated in the survey. Surveys were based on prior questionnaires published in the literature. Descriptive statistics were calculated, and chi-square (ℵ2) analysis, Fisher’s exact test, and Spearman rank correlation analyses were performed. Compared with their peers in HICs, physicians in LMICs reported less experience with cancer pain management despite seeing more cancer patients with advanced disease (41% vs 15.2%, p pain (84% vs 76%) and lack of training and expertise (87% vs 78%) were significantly more prohibitive for physicians in LMICs than those in HICs; p pain management among trainee physicians in low- vs high-resource environments. Understanding these differences may spur further collaboration in the design of contextually relevant solutions, which could potentially help improve the adequacy of cancer pain management

  17. The national cancer institute (NCI) and cancer biology in a 'post genome world'

    International Nuclear Information System (INIS)

    Klausner, Richard D.

    1996-01-01

    The National Cancer Institute (NCI) exists to reduce the burden of all cancers through research and discovery. Extensive restructuring of the NCI over the past year has been aimed at assuring that the institution functions in all ways to promote opportunities for discovery in the laboratory, in the clinic, and in the community. To do this well requires the difficult and almost paradoxical problem of planning for scientific discovery which, in turn is based on the freedom to pursue the unanticipated. The intellectual and structural landscape of science is changing and it places new challenges, new demands and new opportunities for facilitating discovery. The nature of cancer as a disease of genomic instability and of accumulated genetic change, coupled with a possibility of the development of new technologies for reading, utilizing, interpreting and manipulating the genome of single cells, provides unprecedented opportunities for a new type of high through-put biology that will change the nature of discovery, cancer detection, diagnosis, prognosis, therapeutic decision-making and therapeutic discovery. To capture these new opportunities will require attention to be paid to integrate the development of technology and new scientific discoveries with the ability to apply advances rapidly and efficiently through clinical trials

    2012-01-01

    We report a rare finding of two male breast cancer patients with HER2-positive breast cancer who also developed thyroid cancer. We reviewed 45 male breast cancer patients treated in our institution from 2003 to 2008. Only five male breast cancer patients were HER2-positive. In reviewing the published data, we found no cases of thyroid cancer and concurrent breast cancer in men. However, breast cancer and thyroid cancer have shown close association in women. This finding therefore provokes speculation as to whether we should investigate whether women with HER2-positive breast cancer are at a higher risk for thyroid cancer. Although this observation seems to be clinically prevalent, publications are sparse in clinical research areas linking thyroid cancer to breast cancer.

    Full Text Available Background: Cancer, the second most common cause of death, has become a major health problem. Depression is the most common psychological problem encountered in patients with cancer. The coping skills adopted may affect the mental health of patients. Therefore, this research is undertaken to assess the level of depression and coping strategy adopted by the patients diagnosed with cancer. Materials and methods: A descriptive study to assess the level of depression and coping strategy adopted by cancer patients receiving treatment in Mizoram State Cancer Institute, Aizawl was carried out from April to May 2014 with 30 convenient samples. Depression was assessed by using Hospital Anxiety and Depression Scale (HADS developed by Zigmond and Snaith in 1983. Coping strategy adopted by patients were assessed by revised version of the Ways of Coping Checklist developed by Folkman and Lazarus in 1985. Results: Findings of the study showed that depression was universal to all the cancer patients. Majority of cancer patients (66.5% had moderate depression while 13.26% of the cancer patients had severe depression, and only 6.7% of them reported to have low depression. The most effective coping strategy adopted was reappraisal, followed by distancing. There is significant correlation between depression and reappraisal (r=-0.538, p<0.002, and also with depression and acceptance (r=-0.415, p<0.022 strategies. Conclusion: As depression is universal to all cancer patients, use of appropriate coping strategy is very essential to improve their quality of life. The recognition of coping strategies by health team may enable appropriate information and interventions to be provided at optimal times for each individual.

    To systematically categorise cancer research investment awarded to United Kingdom (UK) institutions in the period 2000-2013 and to estimate research investment relative to disease burden as measured by mortality, disability-adjusted life years (DALYs) and years lived with disability (YLDs). Systematic analysis of all open-access data. Public and philanthropic funding to all UK cancer research institutions, 2000-2013. Number and financial value of cancer research investments reported in 2013 UK pounds (UK£). Mortality, DALYs and YLDs data were acquired from the Global Burden of Disease Study. A compound metric was adapted to estimate research investment relative to disease burden as measured by mortality, DALYs and YLDs. We identified 4299 funded studies with a total research investment of £2.4 billion. The highest fundings by anatomical sites were haematological, breast, prostate, colorectal and ovarian cancers. Relative to disease burden as determined by a compound metric combining mortality, DALYs and YLDs, gender-specific cancers were found to be highest funded-the five sites that received the most funding were prostate, ovarian, breast, mesothelioma and testicular cancer; the least well-funded sites were liver, thyroid, lung, upper gastrointestinal (GI) and bladder. Preclinical science accounted for 66.2% of award numbers and 62.2% of all funding. The top five areas of primary research focus by funding were pathogenesis, drug therapy, diagnostic, screening and monitoring, women's health and immunology. The largest individual funder was the Medical Research Council. In combination, the five lowest funded site-specific cancers relative to disease burden account for 47.9%, 44.3% and 20.4% of worldwide cancer mortality, DALYs and YLDs. Research funding for cancer is not allocated according to relative disease burden. These findings are in line with earlier published studies. Funding agencies and industry should openly document their research investments to

    Health care policies and guidelines that are clear and consistent with research evidence are important for maximizing clinical outcomes. To determine whether cancer centers in Canada and the United States had policies and/or guidelines about antioxidant use, and whether policies were aligned with the evidence base, we reviewed current research evidence in the field, and we undertook a survey of the policies and guidelines on antioxidant use at cancer institutions across North America. A survey of policies and guidelines on antioxidant use and the development and communication of the policies and guidelines was conducted by contacting cancer institutions in North America. We also conducted a Website search for each institution to explore any online resources. Policies and guidelines on antioxidant use were collected from 78 cancer institutions. Few cancer institutions had policies (5%) but most provided guidelines (69%). Antioxidants from diet were generally encouraged at cancer institutions, consistent with the current research evidence. In contrast, specific antioxidant supplements were generally not recommended at cancer institutions. Policies and guidelines were developed using evidence-based methods (53%), by consulting another source (35%), or through discussions/conference (26%), and communicated mainly through online resources (65%) or written handouts (42%). For cancer institutions that had no policy or guideline on antioxidants, lack of information and lack of time were the most frequently cited reasons. Policies and guidelines on antioxidants from diet were largely consistent with the research evidence. Policies and guidelines on antioxidant supplements during treatment were generally more restrictive than the research evidence might suggest, perhaps due to the specificity of results and the inability to generalize findings across antioxidants, adding to the complexity of their optimal and safe use.

    Satellite facilities of National Cancer Institute (NCI) cancer centers have expanded their regional footprints. This study characterized geographic access to parent and satellite NCI cancer center facilities nationally overall and by sociodemographics. Parent and satellite NCI cancer center facilities, which were geocoded in ArcGIS, were ascertained. Travel times from every census tract in the continental United States and Hawaii to the nearest parent and satellite facilities were calculated. Census-based population attributes were used to characterize measures of geographic access for sociodemographic groups. From the 62 NCI cancer centers providing clinical care in 2014, 76 unique parent locations and 211 satellite locations were mapped. The overall proportion of the population within 60 minutes of a facility was 22% for parent facilities and 32.7% for satellite facilities. When satellites were included for potential access, the proportion of some racial groups for which a satellite was the closest NCI cancer center facility increased notably (Native Americans, 22.6% with parent facilities and 39.7% with satellite facilities; whites, 34.8% with parent facilities and 50.3% with satellite facilities; and Asians, 40.0% with parent facilities and 54.0% with satellite facilities), with less marked increases for Hispanic and black populations. Rural populations of all categories had dramatically low proportions living within 60 minutes of an NCI cancer center facility of any type (1.0%-6.6%). Approximately 14% of the population (n = 43,033,310) lived more than 180 minutes from a parent or satellite facility, and most of these individuals were Native Americans and/or rural residents (37% of Native Americans and 41.7% of isolated rural residents). Racial/ethnic and rural populations showed markedly improved geographic access to NCI cancer center care when satellite facilities were included.

    This study aimed to determine the incidence and characteristics of HER-2 gene heterogeneity in invasive breast cancer in a single institution. Included were 971 cases of primary invasive breast cancer diagnosed between 2008 and 2010. Fluorescence in situ hybridization (FISH) image files were retrospectively reviewed and HER-2 gene heterogeneity was defined as more than 5% but less than 50% of analyzed invasive tumor cells with a HER-2/Chr17 ratio higher than 2.2, according to the College of American Pathologists guidelines. HER-2 gene heterogeneity was identified in 24 (2.5%) cases. The mean proportion of invasive tumor cells with a HER-2/chromosome 17 ratio higher than 2.2 was 11.6% (range: 5%-25%). Of 24 cases, HER-2 gene status was not amplified in 8, showed borderline amplification in 2, and amplification in 14. All HER-2 amplification cases were low-grade. In conclusion, HER-2 gene heterogeneity of invasive breast cancer is identified in routine FISH examination. This may affect the results of HER-2 gene amplification status in FISH studies.

    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.

    Full Text Available Women in the U.S. Commonwealth of Puerto Rico (PR have a higher age-adjusted incidence rate for uterine cervix cancer than the U.S. mainland as well as substantial access and economic barriers to cancer care. The National Cancer Institute (NCI funds a Minority/Underserved NCI Community Oncology Research Program in PR (PRNCORP as part of a national network of community-based health-care systems to conduct multisite cancer clinical trials in diverse populations. Participation by the PRNCORP in NCI’s uterine cervix cancer clinical trials, however, has remained limited. This study reports on the findings of an NCI site visit in PR to assess barriers impeding site activation and accrual to its sponsored gynecologic cancer clinical trials. Qualitative, semi-structured individual, and group interviews were conducted at six PRNCORP-affiliated locations to ascertain: long-term trial accrual objectives; key stakeholders in PR that address uterine cervix cancer care; key challenges or barriers to activating and to enrolling patients in NCI uterine cervix cancer treatment trials; and resources, policies, or procedures in place or needed on the island to support NCI-sponsored clinical trials. An NCI-sponsored uterine cervix cancer radiation–chemotherapy intervention clinical trial (NCT02466971, already activated on the island, served as a test case to identify relevant patient accrual and site barriers. The site visit identified five key barriers to accrual: (1 lack of central personnel to coordinate referrals for treatment plans, medical tests, and medical imaging across the island’s clinical trial access points; (2 patient insurance coverage; (3 lack of a coordinated brachytherapy schedule at San Juan-centric service providers; (4 limited credentialed radiotherapy machines island-wide; and (5 too few radiology medical physicists tasked to credential trial-specified positron emission tomography scanners island-wide.

    Purpose: This study determined practice patterns in the staging and treatment of patients with stage I non-small cell lung cancer (NSCLC) among National Comprehensive Cancer Network (NCCN) member institutions. Secondary aims were to determine trends in the use of definitive therapy, predictors of treatment type, and acute adverse events associated with primary modalities of treatment. Methods and Materials: Data from the National Comprehensive Cancer Network Oncology Outcomes Database from 2007 to 2011 for US patients with stage I NSCLC were used. Main outcome measures included patterns of care, predictors of treatment, acute morbidity, and acute mortality. Results: Seventy-nine percent of patients received surgery, 16% received definitive radiation therapy (RT), and 3% were not treated. Seventy-four percent of the RT patients received stereotactic body RT (SBRT), and the remainder received nonstereotactic RT (NSRT). Among participating NCCN member institutions, the number of surgeries-to-RT course ratios varied between 1.6 and 34.7 (P<.01), and the SBRT-to-NSRT ratio varied between 0 and 13 (P=.01). Significant variations were also observed in staging practices, with brain imaging 0.33 (0.25-0.43) times as likely and mediastinoscopy 31.26 (21.84-44.76) times more likely for surgical patients than for RT patients. Toxicity rates for surgical and for SBRT patients were similar, although the rates were double for NSRT patients. Conclusions: The variations in treatment observed among NCCN institutions reflects the lack of level I evidence directing the use of surgery or SBRT for stage I NSCLC. In this setting, research of patient and physician preferences may help to guide future decision making.

    The Prostate Cancer Prevention Trial was the first clinical trial to show that a direct intervention (5 mg of finasteride daily for 7 years) could reduce a man's risk of developing prostate cancer. Initial results also suggested that men taking finasteride had an increased risk of developing what appeared to be higher-grade disease (Gleason score 7-10). The National Cancer Institute has a congressional mandate to communicate health information to the public and has established methods to reach the public directly and to reach information intermediaries in the media, professional societies, and advocacy groups. The groundbreaking yet complicated results of the Prostate Cancer Prevention Trial were widely disseminated by National Cancer Institute using the social marketing and public-relations strategies and tactics detailed here.

    There is a paucity of any significant data on the estrogen receptor (ER) and progesterone receptor (PR) status of breast cancer patients from the eastern part of India. This study aims to document the ER and PR status of breast cancer patients in the eastern Indian population, as catered by two premier tertiary care hospitals in Kolkata. All breast cancer patients registered between January 1, 2013 and December 31, 2015, in the Departments of Oncology, of IPGMER and SSKM Hospitals and R. G. Kar Medical College and Hospital, Kolkata, who had at least undergone a core biopsy or surgery, were analyzed retrospectively for documentation of their ER and PR status, using the 2010 American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP) interpretation guidelines. Over a period of 3 years, a total of 927 patients were included for the study. A total of 825 (89%) patients had their ER and PR data available for evaluation. ER and PR positive was seen in 312 (37.82%) patients, ER and PR negative in 399 (48.36%) patients, ER positive and PR negative in 71 (8.6%) patients, and ER negative and PR positive results was found in 43 (5.21%) patients. This is the first multi-institutional documentation of ER and PR status from eastern India, having a modest number of patients and one of the earliest documentations using the latest ASCO/CAP interpretation guidelines. These findings resemble the data from the south and also reiterate the fact that majority of the Indian breast cancer patients are still ER and PR negative in spite of the changes in the interpretation guidelines.

    Improved outcomes of cancer treatment allow patients to undergo treatment while working. However, support from oncologists and medical institutions is essential for patients to continue working. This study aimed to clarify oncologists' awareness and behavior regarding patients who work during treatment, support in medical institutions and their association. A questionnaire was mailed to all 453 diplomates and faculty of the subspecialty board of medical oncology in the Japanese Society of Medical Oncology and all 1016 surgeons certified by the Japanese Board of Cancer Therapy living in the Kanto area. The questionnaire assessed demographics, oncologist awareness and behavior regarding patient employment and support measures at their medical institutions. Logistic regression analysis was used to examine the association of awareness and behavior of oncologists with support measures at their institutions. A total of 668 individuals participated. The overall response rate was 45.5%. Only 53.6% of respondents advised patients to tell their supervisors about prospects for treatment and ask for understanding. For medical institutions, 28.8% had a nurse-involved counseling program and adjustments in radiation therapy (28.0%) and chemotherapy (41.9%) schedules to accommodate patients' work. There was a significant correlation between awareness and behavior of oncologists and medical institutions' measures to support employed cancer patients. There is room for improvement in awareness and behavior of oncologists and support in medical institutions for cancer patients continuing to work. Oncologists could support working patients by exerting influence on their medical institutions. Conversely, proactive development of support measures by medical institutions could alter the awareness and behavior of oncologists.

    Full text: Radiotherapy given concurrently with a cisplatin-based regimen has shown a benefit in patients with locally advanced cervical cancer so becoming the new standard treatment according to EBM criteria. Addition of hyperthermia to radiotherapy has also been proved to yield an advantage in survival and local control in pts affected by recurrent and local advanced cervical cancer in the Dutch Phase III trial so that the Consensus Forum of Kadota (Osaha June 2004) included cervical cancer among tumors treatable with hyperthermia. In our institutional multidisciplinary team a pilot study has been designed in order to evaluate feasibility, outcome and toxicity of tri-modality treatment in pts with locally advanced cervical cancer in our daily practice. Since January 2003 to now eight patients affected by cervical cancer with stage IB2 through IVA N0-N+ pelvic or paraaortic were entered the study. Six patients were treated at initial diagnosis and two patients after chemotherapy which had achieved stable disease. Treatment regimen consisted in 5 courses of weekly chemotherapy (cisplatin 40 mg/mq) with concurrent external radiotherapy to a total dose of 64-66 Gy on CTV1 and 45 Gy on para-aortic nodes plus boost in pts with enlarged nodes identified by imaging. Five weekly sessions of hyperthermia were performed by using BSD 2000 system and sigma 60 applicator. No significant toxicity occurred and all of the patients completed tri-modality treatment in accordance with the study protocol. Seven pts experienced a complete clinical remission and one patient a partial remission as defined by clinical and imaging examinations. After four months from the end of the treatment a patient with Stage IIB bulky tumor plus one pelvic positive node who was in complete remission (Clinical examination, MRI and TAC-PET three months from the end of the treatment were negative for evidence of disease) developed a bleeding recto-vaginal fistula plus central pelvic necrosis for which an

    Full Text Available Abstract Background Gonadotropin releasing hormone (GNRH1 triggers the release of follicle stimulating hormone and luteinizing hormone from the pituitary. Genetic variants in the gene encoding GNRH1 or its receptor may influence breast cancer risk by modulating production of ovarian steroid hormones. We studied the association between breast cancer risk and polymorphisms in genes that code for GNRH1 and its receptor (GNRHR in the large National Cancer Institute Breast and Prostate Cancer Cohort Consortium (NCI-BPC3. Methods We sequenced exons of GNRH1 and GNRHR in 95 invasive breast cancer cases. Resulting single nucleotide polymorphisms (SNPs were genotyped and used to identify haplotype-tagging SNPs (htSNPS in a panel of 349 healthy women. The htSNPs were genotyped in 5,603 invasive breast cancer cases and 7,480 controls from the Cancer Prevention Study-II (CPS-II, European Prospective Investigation on Cancer and Nutrition (EPIC, Multiethnic Cohort (MEC, Nurses' Health Study (NHS, and Women's Health Study (WHS. Circulating levels of sex steroids (androstenedione, estradiol, estrone and testosterone were also measured in 4713 study subjects. Results Breast cancer risk was not associated with any polymorphism or haplotype in the GNRH1 and GNRHR genes, nor were there any statistically significant interactions with known breast cancer risk factors. Polymorphisms in these two genes were not strongly associated with circulating hormone levels. Conclusion Common variants of the GNRH1 and GNRHR genes are not associated with risk of invasive breast cancer in Caucasians.

    The dosimeters TLD-100 and TLD-900 were used to know the levels of environmental dose in areas of the Nuclear Medicine Department of the National Institute of Cancer. The dosimeters calibration was carried out in the Metrology Department of the National Institute of Nuclear Research. The radioisotopes used in the studied areas are 131 I, 18 F, 67 Ga, 99m Tc, 111 In, 201 Tl and 137 Cs with gamma energies between 93 and 662 KeV. Dosimeters were placed during five months in the diagnostic, injection, waiting and PET rooms as well as hot room, waste room, enclosed corridors to patient rooms treated with 131 I and 137 Cs and witness dosimeters to know the bottom. The values found vary between 0.3 and 70 major times that those of bottom. The maximum doses were measured in the waste room and in the enclosed corridor to the patient rooms with cervical uterine cancer treated with 137 Cs. (Author)

    The development of mammography quality control programs at radiology services has had an important progress in the last decades, mainly in developed countries. Although breast cancer is one of the leading causes of cancer mortality and incidence in Colombia, quality control programs for mammography screening are just beginning to be considered. This article describes the results of a baseline evaluation aimed at establishing a quality control program at the Radiology Unit of the National Cancer Institute, in Colombia. The mammography equipment, the film processing, and all main physical parameters were checked and compared to international standards. Quality of the image in 301 mammographic X-ray plates was evaluated. In order to implement a good quality control program, the need for acquiring essential instruments, improving physical facilities and starting a continuous training program is imperative

    Purpose: The optimal locoregional therapy for stage IIIA non-small cell lung cancer (NSCLC) is controversial, with definitive chemoradiation therapy (CRT) and neoadjuvant therapy followed by surgery (NT-S) serving as competing strategies. In this study, we used the National Cancer Database to determine the prevalence and predictors of NT in a large, modern cohort of patients. Methods and Materials: Patients with stage IIIA NSCLC treated with CRT or NT-S between 2003 and 2010 at programs accredited by the Commission on Cancer were included. Predictors were categorized as clinical, time/geographic, socioeconomic, and institutional. In accord with the National Cancer Database, institutions were classified as academic/research program and as comprehensive and noncomprehensive community cancer centers. Logistic regression and random effects multilevel logistic regression were performed for univariable and multivariable analyses, respectively. Results: The cohort consisted of 18,581 patients, 3,087 (16.6%) of whom underwent NT-S (10.6% induction CRT, 6% induction chemotherapy). The prevalence of NT-S was constant over time, but there were significant relative 31% and 30% decreases in pneumonectomy and right-sided pneumonectomy, respectively, over time (P trend <.02). In addition to younger age, lower T stage, and favorable comorbidity score, indicators of higher socioeconomic status were strong independent predictors of NT-S, including white race, higher income, and private/managed insurance. The type of institution (academic/research program vs comprehensive or noncomprehensive community cancer centers, odds ratio 1.54 and 2.08, respectively) strongly predicted NT-S, but treatment volume did not. Conclusions: Neoadjuvant therapy followed by surgery was an uncommon treatment approach in Commission on Cancer programs, and the prevalence of postinduction pneumonectomy decreased over time. Higher socioeconomic status and treatment at academic institutions were significant

    The use of the cannabis plant (Cannabis sativa L.) for the palliative treatment of cancer patients has been legalized in multiple jurisdictions including Israel. Yet, not much is currently known regarding the efficacy and patterns of use of cannabis in this setting. To analyze the indications for the administration of cannabis among adult Israeli cancer patients and evaluate its efficacy. Efficacy and patterns of use of cannabis were evaluated using physician-completed application forms, medical files, and a detailed questionnaire in adult cancer patients treated at a single institution. Of approximately 17,000 cancer patients seen, 279 (cannabis from an authorized institutional oncologist. The median age of cannabis users was 60 years (range 19-93 years), 160 (57%) were female, and 234 (84%) had metastatic disease. Of 151 (54%) patients alive at six months, 70 (46%) renewed their cannabis permit. Renewal was more common among younger patients and those with metastatic disease. Of 113 patients alive and using cannabis at one month, 69 (61%) responded to the detailed questionnaire. Improvement in pain, general well-being, appetite, and nausea were reported by 70%, 70%, 60%, and 50%, respectively. Side effects were mild and consisted mostly of fatigue and dizziness. Cannabis use is perceived as highly effective by some patients with advanced cancer and its administration can be regulated, even by local authorities. Additional studies are required to evaluate the efficacy of cannabis as part of the palliative treatment of cancer patients. Copyright © 2015 American Academy of Hospice and Palliative Medicine.

    Bone marrow necrosis; Egyptian cancer patients Abstract Background: Bone marrow necrosis is a relatively rare entity which has been associated with a poor prognosis. It is most commonly found in patients with neoplastic disorders and severe infections. Methods: study comprised examination of 5043 bone marrow biopsy specimens performed at the National Cancer Institute, Cairo University, over 7 years period (March 2004-March 2011). It included 5 years retrospective (2867 archived samples) and 2 years prospective (2176 samples). Results: Bone marrow necrosis was diagnosed in fifteen out of 5043 examined specimens with a percentage of 0.3% and ranged from mild to massive according to semiquantitative estimation. Prognosis of all patients was poor with survival not exceeding 6 months from the date of marrow necrosis diagnosis. Conclusion: In Egyptian patients, bone marrow necrosis in association with malignancy is a rare disorder which is accompanied by a poor outcome

    2010-01-01

    Purpose: In the absence of randomized study data, institutional case series have shown brachytherapy (BT) to produce excellent biochemical control (bNED) in patients with localized prostate cancer compared with alternative curative treatments. This study was designed to overcome some of the limitations of case series studies by using a matched-pair design in patients treated contemporaneously with BT and external beam radiation therapy (EBRT) at a single institution. Methods and Materials: Six hundred one eligible patients treated between 1998 and 2001 were prospectively followed up in our institutional databases and matched on a 1:1 basis for the following known prognostic variables: prostate-specific antigen (PSA) level, Gleason score, T stage, the use and duration of neoadjuvant androgen deprivation therapy, and the percentage of positive tissue core samples. Two hundred seventy-eight perfect matches of patients (139 in each group) with low- and intermediate-risk cancer were further analyzed. bNED (Phoenix definition) was the primary endpoint. Other endpoints were toxicity, PSA kinetics, and the secondary use of androgen deprivation therapy. Results: The 5-year bNED rates were 95% (BT) and 85% (EBRT) (p < 0.001). After 7 years, the BT bNED result was unchanged, but the rate in EBRT patients had fallen to 75%. The median posttreatment PSA nadirs were 0.04 ng/mL (BT) and 0.62 ng/mL (EBRT, p < 0.001), which predicted a higher ongoing treatment failure rate in association with EBRT use than with BT use. Late urinary toxicity and rectal/bowel toxicity were worse in patients treated with BT and EBRT, respectively. Conclusions: BT for both low-risk and selected intermediate-risk cancers achieves exceptional cure rates. Even with dose escalation, it will be difficult for EBRT to match the proven track record of BT seen over the past decade.

    We examined the geographic distribution of patients to better understand the service area of the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins, a designated National Cancer Institute (NCI) comprehensive cancer center located in an urban center. Like most NCI cancer centers, the Sidney Kimmel Comprehensive Cancer Center serves a population beyond city limits. Urban cancer centers are expected to serve their immediate neighborhoods and to address disparities in access to specialty care. Our purpose was to learn the extent and nature of the cancer center service area. Statistical clustering of patient residence in the continental United States was assessed for all patients and by gender, cancer site, and race using SaTScan. Primary clusters detected for all cases and demographically and tumor-defined subpopulations were centered at Baltimore City and consisted of adjacent counties in Delaware, Pennsylvania, Virginia, West Virginia, New Jersey and New York, and the District of Columbia. Primary clusters varied in size by race, gender, and cancer site. Spatial analysis can provide insights into the populations served by urban cancer centers, assess centers' performance relative to their communities, and aid in developing a cancer center business plan that recognizes strengths, regional utility, and referral patterns. Today, 62 NCI cancer centers serve a quarter of the U.S. population in their immediate communities. From the Baltimore experience, we might project that the population served by these centers is actually more extensive and varies by patient characteristics, cancer site, and probably cancer center services offered.

    Full Text Available Objective. To estimate the annual cost of the National Cervical Cancer Screening Program (CCSP of the Mexican Institute of Social Security (IMSS. Materials and methods. This cost analysis examined regional coverage rates reported by IMSS. We estimated the number of cytology, colposcopy, biopsy and pathology evaluations, as well as the diagnostic test and treatment costs for cervical intraepithelial neoplasia grade II and III (CIN 2/3 and cervical cancer. Diagnostic test costs were estimated using a micro-costing technique. Sensitivity analyses were performed. Results. The cost to perform 2.7 million cytology tests was nearly 38 million dollars, which represents 26.1% of the total program cost (145.4 million. False negatives account for nearly 43% of the program costs. Conclusion. The low sensitivity of the cytology test generates high rates of false negatives, which results in high institutional costs from the treatment of undetected cervical cancer cases.

    Data protection is important for all information systems that deal with human-subjects data. Grid-based systems--such as the cancer Biomedical Informatics Grid (caBIG)--seek to develop new mechanisms to facilitate real-time federation of cancer-relevant data sources, including sources protected under a variety of regulatory laws, such as HIPAA and 21CFR11. These systems embody new models for data sharing, and hence pose new challenges to the regulatory community, and to those who would develop or adopt them. These challenges must be understood by both systems developers and system adopters. In this paper, we describe our work collecting policy statements, expectations, and requirements from regulatory decision makers at academic cancer centers in the United States. We use these statements to examine fundamental assumptions regarding data sharing using data federations and grid computing. An interview-based study of key stakeholders from a sample of US cancer centers. Interviews were structured, and used an instrument that was developed for the purpose of this study. The instrument included a set of problem scenarios--difficult policy situations that were derived during a full-day discussion of potentially problematic issues by a set of project participants with diverse expertise. Each problem scenario included a set of open-ended questions that were designed to elucidate stakeholder opinions and concerns. Interviews were transcribed verbatim and used for both qualitative and quantitative analysis. For quantitative analysis, data was aggregated at the individual or institutional unit of analysis, depending on the specific interview question. Thirty-one (31) individuals at six cancer centers were contacted to participate. Twenty-four out of thirty-one (24/31) individuals responded to our request- yielding a total response rate of 77%.

    Occult cancers' reported rates vary from 2-12% and serous tubal intraepithelial carcinomas (STICs) have been identified in 3-12% of the prophylactically removed tubes of women carrying a BRCA mutation. The aim of this study was to evaluate the incidence of tubal minor epithelial atypia (STIL), STIC, and occult invasive cancer and to evaluate the cancer-specific mortality in a prospective series of women at higher risk of ovarian and breast cancer undergoing risk-reducing salpingo-oophorectomy (RRSO) n a tertiary cancer center. A series of RRSO specimens (including endometrial biopsy) from women carrying a BRCA mutation, BRCA-unknown and BRCA-negative were collected between January 1998 and April 2016 at the Division of Gynecology at the European Institute of Oncology. Inclusion criteria were: asymptomatic women who had a negative gynecologic screening within 3 months prior to RRSO. Exclusion criteria were: women with ovarian/tubal cancer prior to RRSO. A total of 411 women underwent RRSO. Median age at RRSO was 47.0 years (range=32-70 years); 75.2% had a history of breast cancer. Fifteen women were diagnosed with an occult cancer (7 STIC, 4 invasive cancers, 2 breast cancers metastatic to the adnexa, 2 endometrial cancer) (3.6%). Sixteen showed a STIL (3.9%). When excluding cases with preoperative positive markers, the occult invasive cancer rate drops to 1.5%. Our study, covering an 18-year period, shows a substantial low risk of occult cancer among a high-risk population of women undergoing RRSO. Our data still support the indication for RRSO in higher-risk patients. An endometrial biopsy should also be routinely obtained as it raises the chances of detecting occult endometrial cancers that may be otherwise missed.

    Modifiable lifestyle factors linked to cancer offer great potential for prevention. Previous studies suggest an association between adherence to recommendations on healthy lifestyle and cancer mortality. The aim of this study was to examine whether adherence to the cancer prevention recommendations of the World Cancer Research Fund (WCRF) and the American Institute for Cancer Research (AICR) is associated with reduced all-cause, total cancer, and specific cancer type mortality. We built a lifestyle score that included 3 categories, based on the recommendations of the WCRF/AICR. Applying Cox regression models, we investigated the association with all-cause, total cancer, and specific cancer type mortality; in addition, we included cardiovascular disease (CVD) mortality. We used census- and death registry-linked survey data allowing a mortality follow-up for ≤32 y. Our analysis included 16,722 participants. Information on lifestyle score components and confounders was collected at baseline. Over a mean follow-up of 21.7 y, 3730 deaths were observed (1332 cancer deaths). Comparing best with poorest category of the lifestyle score showed an inverse association with all-cause (HR: 0.82; 95% CI: 0.75, 0.89) and total cancer (men only, HR: 0.69; 95% CI: 0.57, 0.84) mortality. We estimated that ∼13% of premature cancer deaths in men would have been preventable if lifestyle score levels had been high. Inverse associations were observed for lung, upper aerodigestive tract, stomach, and prostate cancer mortality [men and women combined, HR: 0.72; 95% CI: 0.51, 0.99; HR: 0.49; 95% CI: 0.26, 0.92; HR: 0.34; 95% CI: 0.14, 0.83; HR: 0.48; 95% CI: 0.28, 0.82 (men only), respectively]. CVD mortality was not associated with the lifestyle score (men and women combined, HR: 0.96; 95% CI: 0.82, 1.13). Our results support the importance of adhering to recommendations for a healthy lifestyle with regard to all-cause and cancer mortality. To reduce the burden of cancer in the

    Background: The available literature on minimally invasive colorectal cancer demonstrates that laparoscopic approach is feasible and associated with better short term outcomes than open surgery while maintaining equivalent oncologic safety. Reports have shown that robotic surgery may overcome some of the pitfalls of laparoscopic intervention. Objective of the work: To evaluate early results of robotic colorectal surgery, in a cohort of Egyptian patients, regarding operative time, operative and early post-operative complications, hospital stay and pathological results. Patients and methods: A case series study which was carried out in surgical department at National Cancer Institute, Cairo University. Ten Egyptian cases of colorectal cancer (age ranged from 30 to 67, 5 males and 5 females) were recruited from the period of April 2013 to April 2014. Robotic surgery was performed to all cases. Results: Three patients had low anterior resection, three anterior resection, one total proctectomy, one abdominoperineal resection, one left hemicolectomy and one colostomy. The study reported no mortalities and two morbidities. The mean operative time was 333 min. The conversion to open was done in only one patient. A total mesorectal excision with negative circumferential margin was accomplished in all patients, distal margin was positive in one patient. Mean lymph nodes removed was 10.7. Mean hospital stay was 7.4 days. Conclusion: To the best of our knowledge, this is the first study reporting the outcomes of robotic colorectal cancer intervention in Egyptian patients. Our preliminary results suggest that robotic- assisted surgery for colorectal cancer can be carried out safely and according to oncological principles

    The screening and the early detection of the premalignant and malignant lesions are the only means for controlling the oral cancer which is known to be one of the leading causes for mortality worldwide. Oral exfoliative cytology though not a substitute for biopsy can be a powerful tool for its early detection. Dental Surgeons can play a great role in this direction. The present study was undertaken to assess the self-reported knowledge and attitude regarding the early detection of oral cancer and exfoliative cytology among the undergraduates of Rama Dental College, Kanpur. A pretested questionnaire based cross sectional study consisting of twenty four questions was conducted among hundred randomly selected students from third year, final year and intern's batch. According to 73% of students biopsy was the special test done in oral cancer detection and only 59% had heard regarding oral cytology technique. Formalin was the fixative known for cytology smears among 61%. Significance of toluidine blue staining was not known by 62%. Seventy seven percent of students were not aware about classes of cytology reporting. Eighty six percent of students felt that the adequacy of training in cytology was lagging. This survey identified an existing gap in the knowledge among the dental students regarding cytology as a diagnostic aid in oral cancer detection. This emphasizes the need to provide training for undergraduates at clinical level on regular basis and also through CDE and oral can-cer detection workshops.

    Malnutrition is common among cancer patients. This study aimed to determine the overall prevalence of malnutrition among patients undergoing chemotherapy and to determine the predictors of malnutrition among cancer patients. A cross-sectional study was conducted on 88 cancer patients admitted for chemotherapy at the National Kidney and Transplant Institute, Philippines, from October to November 2009. Subjective Global Assessment (SGA), anthropometric data and demographic variables were obtained. Descriptive statistics, ANOVA and logistic regression analysis were performed between the outcome and variables. A total of 88 cancer patients were included in the study. The mean age of the patients was 55.7 +/- 14.8 years. The mean duration of illness was 9.7 +/- 8.7 months and the mean body mass index (BMI) was 22.9 kg/m2. The mean Karnofsky performance status was 79.3. 29.55 percent of the patients had breast cancer as the aetiology of their illness. 38 patients (43.2 percent) had SGA B and four (4.5 percent) had SGA C, giving a total malnutrition prevalence of 47.7 percent. The patients were statistically different with regard to their cancer stage (p is less than 0.001), weight (p is 0.01), BMI (p is 0.004), haemoglobin level (p is 0.001) and performance status by Karnofsky score (p is less than 0.001), as evaluated by ANOVA. Logistic regression analysis showed that cancer stage and Karnofsky performance score were predictors of malnutrition. About 47.7 percent of cancer patients suffer from malnutrition, as classified by SGA. Only cancer stage and Karnofsky performance status scoring were predictive of malnutrition in this select group of patients.

    Assessment of the nursing staff knowledge, attitude and practices about cervical cancer screening in a tertiary care teaching institute of rural India. A cross sectional, descriptive, interview- based survey was conducted with a pretested questionnaire among 262 staff nurses of a tertiary care teaching and research institute. In this study 77% respondents knew that Pap smear is used for detection of cervical cancer, but less than half knew that Pap smear can detect even precancerous lesions of cervix. Only 23.4% knew human papilloma virus infection as a risk factor. Only 26.7% of the respondents were judged as having adequate knowledge based on scores allotted for questions evaluating knowledge about cervical cancer and screening. Only 17 (7%) of the staff nurses had themselves been screened by Pap smear, while 85% had never taken a Pap smear of a patient. Adequate knowledge of cervical cancer and screening, higher parity and age >30 years were significantly associated with self screening for cervical cancer. Most nurses held a view that Pap test is a doctor procedure, and nearly 90% of nurses had never referred a patient for Pap testing. The majority of nursing staff in rural India may have inadequate knowledge about cervical cancer screening, and their attitude and practices towards cervical cancer screening could not be termed positive.

    Introduction Gastric cancer represents a great challenge for healthcare providers and requires a multidisciplinary treatment approach in which surgery plays a major role. Minimally invasive surgery has been progressively developed, first with the advent of laparoscopy and recently with the spread of robotic surgery, but a number of issues are currently being debated, including the limitations in performing an effective extended lymph node dissection, the real advantages of robotic systems, the role of laparoscopy for Advanced Gastric Cancer, the reproducibility of a total intracorporeal technique and the oncological results achievable during long-term follow-up. Methods and analysis A multi-institutional international database will be established to evaluate the role of robotic, laparoscopic and open approaches in gastric cancer, comprising of information regarding surgical, clinical and oncological features. A chart review will be conducted to enter data of participants with gastric cancer, previously treated at the participating institutions. The database is the first of its kind, through an international electronic submission system and a HIPPA protected real time data repository from high volume gastric cancer centres. Ethics and dissemination This study is conducted in compliance with ethical principles originating from the Helsinki Declaration, within the guidelines of Good Clinical Practice and relevant laws/regulations. A multicentre study with a large number of patients will permit further investigation of the safety and efficacy as well as the long-term outcomes of robotic, laparoscopic and open approaches for the management of gastric cancer.

    In 2002, the National Cancer Institute created the Initiative for Chemical Genetics (ICG), to enable public research using small molecules to accelerate the discovery of cancer-relevant small-molecule probes. The ICG is a public-access research facility consisting of a tightly integrated team of synthetic and analytical chemists, assay developers, high-throughput screening and automation engineers, computational scientists, and software developers. The ICG seeks to facilitate the cross-fertilization of synthetic chemistry and cancer biology by creating a research environment in which new scientific collaborations are possible. To date, the ICG has interacted with 76 biology laboratories from 39 institutions and more than a dozen organic synthetic chemistry laboratories around the country and in Canada. All chemistry and screening data are deposited into the ChemBank web site (http://chembank.broad.harvard.edu/) and are available to the entire research community within a year of generation. ChemBank is both a data repository and a data analysis environment, facilitating the exploration of chemical and biological information across many different assays and small molecules. This report outlines how the ICG functions, how researchers can take advantage of its screening, chemistry and informatic capabilities, and provides a brief summary of some of the many important research findings.

    Background To determine the prevalence and clinicopathologic features of the oral cancer patients. Material and Methods Biopsy records of the participating institutions were reviewed for oral cancer cases diagnosed from 2005 to 2014. Demographic data and site of the lesions were collected. Sites of the lesion were subdivided into lip, tongue, floor of the mouth, gingiva, alveolar mucosa, palate, buccal/labial mucosa, maxilla and mandible. Oral cancer was subdivided into 7 categories: epithelial tumors, salivary gland tumors, hematologic tumors, bone tumors, mesenchymal tumors, odontogenic tumors, and others. Data were analyzed by descriptive statistics using SPSS software version 17.0. Results Of the 474,851 accessioned cases, 6,151 cases (1.30%) were diagnosed in the category of oral cancer. The mean age of the patients was 58.37±15.77 years. A total of 4,238 cases (68.90%) were diagnosed in males, whereas 1911 cases (31.07%) were diagnosed in females. The male-to-female ratio was 2.22:1. The sites of predilection for oral cancer were tongue, labial/buccal mucosa, gingiva, palate, and alveolar mucosa, respectively. The three most common oral cancer in the descending order of frequency were squamous cell carcinoma, non-Hodgkin lymphoma and mucoepidermoid carcinoma. Conclusions Although the prevalence of oral cancer is not high compared to other entities, oral cancer pose significant mortality and morbidity in the patients, especially when discovered late in the course of the disease. This study highlights some anatomical locations where oral cancers are frequently encountered. As a result, clinicians should pay attention to not only teeth, but oral mucosa especially in the high prevalence area as well since early detection of precancerous lesions or cancers in the early stage increase the chance of patient being cured and greatly reduce the mortality and morbidity. This study also shows some differences between pediatric and elderly oral cancer patients as well as

    The National Cancer Institute has been a leader in supporting transdisciplinary (TD) team science. From 2005-2010, the NCI supported Transdisciplinary Research on Energetic and Cancer I (TREC I), a center initiative fostering the TD integration of social, behavioral, and biological sciences to examine the relationships among obesity, nutrition, physical activity and cancer. In the final year of TREC I, we conducted qualitative in-depth-interviews with 31 participating investigators and trainees to learn more about their experiences with TD team science, including challenges, facilitating factors, strategies for success, and impacts. Five main challenges emerged: (1) limited published guidance for how to engage in TD team science, when TREC I was implemented; (2) conceptual and scientific challenges inherent to efforts to achieve TD integration; (3) discipline-based differences in values, terminology, methods, and work styles; (4) project management challenges involved in TD team science; and (5) traditional incentive and reward systems that do not recognize or reward TD team science. Four main facilitating factors and strategies for success emerged: (1) beneficial attitudes and beliefs about TD research and team science; (2) effective team processes; (3) brokering and bridge-building activities by individuals holding particular roles in a research center; and (4) funding initiative characteristics that support TD team science. Broad impacts of participating in TD team science in the context of TREC I included: (1) new positive attitudes about TD research and team science; (2) new boundary-crossing collaborations; (3) scientific advances related to research approaches, findings, and dissemination; (4) institutional culture change and resource creation in support of TD team science; and (5) career advancement. Funding agencies, academic institutions, and scholarly journals can help to foster TD team science through funding opportunities, institutional policies on

    Full text of publication follows: Women who are treated for early breast cancer with adjuvant radiation have a decreased risk of local recurrence but an increased risk of mortality from heart disease and lung cancer. Patients with left -sided breast tumors receive a higher dose of radiation to the heart than patients with right-sided tumors. In a previous study of about 300000 women treated for breast cancer during 1973-2001 and followed-up prospectively for cause-specific mortality until January 1, 2002, Sarah Darby showed that for women diagnosed during 1973-1982 and irradiated, the cardiac mortality ratio (left versus right tumor laterality) was 1.20 [1.04-1.38] less then 10 years afterwards, and 1.58 [1.29 - 1.95] after 15 years or more. Because radiation techniques have improved over time, such risks are expected to be reduced. A cohort was performed at Institute Gustave Roussy to investigate long term effects of breast cancer treatments. This cohort comprise 7711 women treated for beast cancer between 1954 and 1984. Mean age at the first treatment was 55 years [21 - 91], 61% were diagnosed before 1977 vs 39% after, 50.4% were left -sided breast cancer, 4832 (73.2 %) were recorded as having received external-beam radiotherapy as part of the initial treatment and 516 (8%) radiotherapy in association with chemotherapy. The aim of the present study is to investigate long term mortality and effects of radiotherapy on mortality from cardiac disease and second cancers. The originality of our study comparing to similar others is the homogeneity of the population studied and the longer follow-up. Vital status and causes of death of women of the cohort were obtained as well as mortality rates in the general French population. The cut off date was January 1, 2001.

    Population-based cancer registries from Algeria, China, Costa Rica, Cuba, India, the Philippines, and Thailand are collaborating with the International Agency for Research on Cancer in a study of cancer survival in developing countries. Comparisons with the SEER program results of the National Cancer Institute in the United States, and the EUROCARE study of survival in European countries revealed considerable differences in the survival of patients with certain tumors associated with intensive chemotherapeutic treatment regimes (Hodgkin's disease and testicular tumors), more modest differences in the survival of patients with tumors for which early diagnosis and treatment confer an improved prognosis (carcinomas of the large bowel, breast, and cervix), and only slight differences for tumors associated with poor prognosis (carcinomas of the stomach, pancreas, and lung). With limited resources to meet the challenge of the increasing incidence of cancer expected in the next few decades, health authorities in developing countries should be aware of the importance of investing in a range of cancer control activities, including primary prevention and early detection programs as well as treatment.

    To survey thought leaders attending an annual bladder cancer conference about resources available to survivors at, primarily, large academic centers treating a high volume of patients. Bladder cancer is a disease with high treatment burden. Support groups and survivorship programs are effective at managing physical and psychosocial impairments experienced by patients. The Institute of Medicine recommends increased resources for cancer survivorship, but no description of current resources exists for bladder cancer patients. Preceding the 4th annual Bladder Cancer Think Tank meeting in August 2009, we carried out an Internet-based survey of registrants that queried respondents about institutional resources and support systems devoted to bladder cancer survivors. Data were collected using SurveyMonkey.com, and descriptive statistics were computed. A total of 43 eligible respondents included urologists (77%), medical oncologists (16%), and other physicians or health professionals (7%). Physician respondents represented 22 academic centers and 2 private groups. Although 63% of respondent institutions had a National Cancer Institute designation, only 33% had an active bladder cancer support group. Survivorship clinics were available in 29% of institutions, and peer support networks, community resources for education, and patient navigation were available in 58%, 13%, and 25% of respondent institutions, respectively. Resources for bladder cancer survivors vary widely and are lacking at several academic centers with high-volume bladder cancer populations. Bladder cancer providers are often unaware of available institutional resources for patients. Urologists need to advocate for additional survivor resources and partner with other disciplines to provide appropriate care. Copyright © 2012 Elsevier Inc. All rights reserved.

    Childhood cancer survivors who have received treatment with anthracyclines are at risk for developing cardiomyopathy in dose-dependent fashion. Historically, restrictions on certain types of physical activity that were intended to preserve cardiac function have been recommended, based on a mixture of evidence-based and consensus-based recommendations. In the LIFE Cancer Survivorship & Transition Program at Children's Hospital Los Angeles, the authors reevaluated their recommendations for exercise in survivors who were exposed to anthracyclines, with or without irradiation in proximity to the myocardium. The primary goal was to develop consistent, specific, practical, safe, and (where possible) evidence-based recommendations for at-risk survivors in the program. To accomplish this, the authors referred to current exercise guidelines for childhood cancer survivors, consulted recent literature for relevant populations, and obtained input from the program's pediatric cardiology consultant. The resulting risk-based exercise recommendations are designed to complement current published guidelines, maximize safe exercise, and help childhood cancer survivors return to a normal life that emphasizes overall wellness and physical activity. This article describes a single institution's experience in modifying exercise recommendations for at-risk childhood survivors and includes the methods, findings, and current institutional practice recommendations along with sample education materials.

    Aims to give an overview of the re-engineering of processes and structures at Gujarat Cancer Research Institute (GCRI), Ahmedabad. A general review of the design, development and implementation of reengineered systems in order to address concerns about the existing systems. Findings GCRI is a comprehensive cancer care center with 550 beds and well equipped with modern diagnostic and treatment facilities. It serves about 200,000 outpatients and 16,000 inpatients annually. The approach to a better management of hospital supplies led to the design, development, and implementation of an IT-based reengineered and integrated purchase and inventory management system. The new system has given GCRI a saving of about 8 percent of its annual costs of purchases, and improved the availability of materials to the user departments. Shows that the savings obtained are used not only for buying more hospital supplies, but also to buy better quality of hospital supplies, and thereby satisfactorily address the GCRI responsibility towards meeting its social obligations for cancer care.

    Since their inception in the 1950s, the National Cancer Institute-funded cancer cooperative groups have been important contributors to cancer clinical and translational research. In 2010, a committee appointed by the Institute of Medicine (IOM) of the National Academy of Sciences completed a consensus review on the status of the U.S. publicly funded cancer clinical trials system. This report identified a need to reinvigorate the cooperative groups and provided recommendations for improving their effectiveness. Follow-up workshops to monitor progress were conducted by the IOM's National Cancer Policy Forum and the American Society of Clinical Oncology (ASCO) in 2011 and 2013. One of the key recommendations of the IOM report was a call for greater collaboration among stakeholders in cancer research. In particular, more active engagement and better alignment of incentives among the cooperative groups, the National Cancer Institute, the U.S. Food and Drug Administration, and the biopharmaceutical industry were identified as essential to achieving the promise of oncology drug development. This review, based on presentations and discussion during the IOM-ASCO workshops, outlines the progress and remaining challenges of these collaborations. ©AlphaMed Press.

    Different publications show an increased incidence of neoplasms in renal transplant patients. The objective of this study is to determine the incidence of cancer in the recipients of renal transplants performed in the A Coruña Hospital (Spain) during the period 1981–2007. During the study period 1967 kidney transplants were performed, corresponding to 1710 patients. Patients with neoplasms prior to the transplant will be excluded (n = 38). A follow-up study was carried out in order to estimate cancer incidence after transplantation. For each patient, information included donor and recipient characteristics, patients and graft survival and cancer incidence after transplantation. Incident cancer is considered as new cases of cancer after the transplant with anatomopathological confirmation. Their location will be classified according to the ICD-9. The analysis will be calculated using the indirect standardisation method. Age-adjusted cancer incidence rates in the Spanish general population will be obtained from the Carlos III Health Institute, the National Epidemiology Centre of the Ministry of Science and Technology. Crude first, second and third-year post-transplantation cancer incidence rates will be calculated for male and female recipients. The number of cases of cancer at each site will be calculated from data in the clinical records. The expected number of cancers will be calculated from data supplied by the Carlos III Health Institute. For each tumour location we will estimate the standardized incidence ratios (SIRs), using sex-specific cancer incidence rates, by dividing the incidence rate for the transplant patients by the rate of the general population. The 95% confidence intervals of the SIRs and their associated p-values will be calculated by assuming that the observed cancers follow a Poisson distribution. Stratified analysis will be performed to examine the variation in the SIRs with sex and length of follow-up. Competing risk survival analysis

    To determine the prevalence and clinicopathologic features of the oral cancer patients. Biopsy records of the participating institutions were reviewed for oral cancer cases diagnosed from 2005 to 2014. Demographic data and site of the lesions were collected. Sites of the lesion were subdivided into lip, tongue, floor of the mouth, gingiva, alveolar mucosa, palate, buccal/labial mucosa, maxilla and mandible. Oral cancer was subdivided into 7 categories: epithelial tumors, salivary gland tumors, hematologic tumors, bone tumors, mesenchymal tumors, odontogenic tumors, and others. Data were analyzed by descriptive statistics using SPSS software version 17.0. Of the 474,851 accessioned cases, 6,151 cases (1.30%) were diagnosed in the category of oral cancer. The mean age of the patients was 58.37±15.77 years. A total of 4,238 cases (68.90%) were diagnosed in males, whereas 1911 cases (31.07%) were diagnosed in females. The male-to-female ratio was 2.22:1. The sites of predilection for oral cancer were tongue, labial/buccal mucosa, gingiva, palate, and alveolar mucosa, respectively. The three most common oral cancer in the descending order of frequency were squamous cell carcinoma, non-Hodgkin lymphoma and mucoepidermoid carcinoma. Although the prevalence of oral cancer is not high compared to other entities, oral cancer pose significant mortality and morbidity in the patients, especially when discovered late in the course of the disease. This study highlights some anatomical locations where oral cancers are frequently encountered. As a result, clinicians should pay attention to not only teeth, but oral mucosa especially in the high prevalence area as well since early detection of precancerous lesions or cancers in the early stage increase the chance of patient being cured and greatly reduce the mortality and morbidity. This study also shows some differences between pediatric and elderly oral cancer patients as well as between Asian and non-Asian oral cancer patients.

    Purpose: To report the long-term survival and toxicity of a multi-institutional phase 2 study of concurrent chemoradiation therapy (CCRT) for locally advanced cervical cancer in east and southeast Asia. Methods and Materials: Ten institutions from 8 Asian countries participated in the study. Between April 2003 and March 2006, 120 patients (60 with bulky stage IIB and 60 with stage IIIB) were treated with CCRT. Radiation therapy consisted of pelvic external beam radiation therapy and either high-dose-rate or low-dose-rate intracavitary brachytherapy. Five cycles of weekly cisplatin (40 mg/m{sup 2}) were administered during the course of radiation therapy. Treatment results were evaluated by the rates of local control, overall survival, and late toxicities. Results: Median follow-up was 63.7 months, and the follow-up rate at 5 years was 98%. The 5-year local control and overall survival rates for all patients were 76.8% and 55.1%, respectively. The 5-year rates of major late toxicities of the rectum and bladder were 7.9% and 0%, respectively. Conclusions: The long-term results have suggested that CCRT is safe and effective for patients with locally advanced cervical cancer in east and southeast Asia. However, further efforts are needed to improve overall survival.

    Medical care for clinical trials is often not reimbursed by insurers, primarily because of concern that medical care as part of clinical trials is expensive and not part of standard medical practice. In June 2000, President Clinton ordered Medicare to reimburse for medical care expenses incurred as part of cancer clinical trials, although many private insurers are concerned about the expense of this effort. To inform this policy debate, the costs and charges of care for patients on clinical trials are being evaluated. In this Association of American Cancer Institutes (AACI) Clinical Trials Costs and Charges pilot study, we describe the results and operational considerations of one of the first completed multisite economic analyses of clinical trials. Our pilot effort included assessment of total direct medical charges for 6 months of care for 35 case patients who received care on phase II clinical trials and for 35 matched controls (based on age, sex, disease, stage, and treatment period) at five AACI member cancer centers. Charge data were obtained for hospital and ancillary services from automated claims files at individual study institutions. The analyses were based on the perspective of a third-party payer. The mean age of the phase II clinical trial patients was 58.3 years versus 57.3 years for control patients. The study population included persons with cancer of the breast (n = 24), lung (n = 18), colon (n = 16), prostate (n = 4), and lymphoma (n = 8). The ratio of male-to-female patients was 3:4, with greater than 75% of patients having stage III to IV disease. Total mean charges for treatment from the time of study enrollment through 6 months were similar: $57,542 for clinical trial patients and $63,721 for control patients (1998 US$; P =.4) Multisite economic analyses of oncology clinical trials are in progress. Strategies that are not likely to overburden data managers and clinicians are possible to devise. However, these studies require careful planning

    A bibliometric study was carried out to describe the scientific production on cancer written by Peruvians and published in international health journals, as well as to assess the scientific collaboration networks. It included articles on cancer written in Peru between the years 2000 and 2011 and published in health journals indexed in SCOPUS or Science Citation Index Expanded. In the 358 articles identified, an increase in the production was seen, from 4 articles in 2000 to 57 in 2011.The most studied types were cervical cancer (77 publications); breast cancer (53), and gastric cancer (37). The National Institute of Neoplastic Diseases (INEN) was the most productive institution (121 articles) and had the highest number of collaborations (180 different institutions). 52 clinical trials were identified, 29 of which had at least one author from INEN. We can conclude that, cancer research is increasing in Peru, the INEN being the most productive institution, with an important participation in clinical trials.

    Cancer cells contain multiple genetic changes in cell signaling pathways that drive abnormal cell survival, proliferation, invasion, and metastasis. Unfortunately, patients treated with single agents inhibiting only one of these pathways--even if showing an initial response--often develop resistance with subsequent relapse or progression of their cancer, typically via the activation of an alternative uninhibited pathway. Combination therapies offer the potential for inhibiting multiple targets and pathways simultaneously to more effectively kill cancer cells and prevent or delay the emergence of drug resistance. However, there are many unique challenges to developing combination therapies, including devising and applying appropriate preclinical tests and clinical trial designs, prioritizing which combination therapies to test, avoiding overlapping toxicity of multiple agents, and overcoming legal, cultural, and regulatory barriers that impede collaboration among multiple companies, organizations, and/or institutions. More effective strategies to efficiently develop combination cancer therapies are urgently needed. Thus, the Institute of Medicine's National Cancer Policy Forum recently convened a workshop with the goal of identifying barriers that may be impeding the development of combination investigational cancer therapies, as well as potential solutions to overcome those barriers, improve collaboration, and ultimately accelerate the development of promising combinations of investigational cancer therapies. ©2012 AACR.

    Case-control studies have used a variety of measurements to evaluate the relationship of children's exposure to magnetic fields (50 or 60 Hz) with childhood leukaemia and other childhood cancers. In the absence of knowledge about which exposure metrics may be biologically meaningful, studies during the past 10 years have often used time-weighted average (TWA) summaries of home measurements. Recently, other exposure metrics have been suggested, usually based on theoretical considerations or limited laboratory data. In this paper, the rationale and associated preliminary studies undertaken are described as well as feasibility and validity issues governing the choice of the primary magnetic field exposure assessment methods and summary metric used to estimate children's exposure in the National Cancer Institute/Children's Cancer Group (NCI/CCG) case-control study. Also provided are definitions and discussion of the strengths and weaknesses of the various exposure metrics used in exploratory analyses of the NCI/CCG measurement data. Exposure metrics evaluated include measures of central tendency (mean, median, 30th to 70th percentiles), peak exposures (90th and higher percentiles, peak values of the 24 h measurements), and measurements of short-term temporal variability (rate of change). This report describes correlations of the various metrics with the time-weighted average for the 24 h period (TWA-24-h). Most of the metrics were found to be positively and highly correlated with TWA-24-h, but lower correlations of TWA-24-h with peak exposure and with rate of change were observed. To examine further the relation between TWA and alternative metrics, similar exploratory analysis should be considered for existing data sets and for forthcoming measurement investigations of residential magnetic fields and childhood leukaemia.

    Since their inception in the 1950s, the National Cancer Institute-funded cancer cooperative groups have been important contributors to cancer clinical and translational research. In 2010, a committee appointed by the Institute of Medicine (IOM) of the National Academy of Sciences completed a consensus review on the status of the U.S. publicly funded cancer clinical trials system. This report identified a need to reinvigorate the cooperative groups and provided recommendations for improving their effectiveness. Follow-up workshops to monitor progress were conducted by the IOM’s National Cancer Policy Forum and the American Society of Clinical Oncology (ASCO) in 2011 and 2013. One of the key recommendations of the IOM report was a call for greater collaboration among stakeholders in cancer research. In particular, more active engagement and better alignment of incentives among the cooperative groups, the National Cancer Institute, the U.S. Food and Drug Administration, and the biopharmaceutical industry were identified as essential to achieving the promise of oncology drug development. This review, based on presentations and discussion during the IOM-ASCO workshops, outlines the progress and remaining challenges of these collaborations. PMID:25326161

    Full Text Available Introduction: Diagnosis of cancer can cause huge spiritual crisis in a person and affect different aspects of life. At this stage, patients have certain spiritual needs. Aim: This study was conducted to explain spiritual needs of cancer patients in Iran. Materials and Methods: In this qualitative study, 18 cancer patients, referred to the Cancer Institute of Imam Khomeini Hospital in Tehran were selected using purposive sampling method, and their spiritual needs emerged out of conventional content analysis of interviews conducted with them. Results: From 1850 initial codes, 4 themes (connection, peace, meaning and purpose, and transcendence were identified that contained categories of social support, normal behavior, inner peace, seeking forgiveness, hope, acceptance of reality, seeking meaning, ending well, change of life meaning, strengthening spiritual belief, communication with God, and prayer. Conclusions: Spiritual needs of cancer patients should be recognized, realized, and considered in care of patients by the medical team. An all-out support of health system policy makers to meet patients′ spiritual needs is particularly important.

    New generations of tumor markers used to detect prostate cancer (PCa) should be able to discriminate men with aggressive PCa of those without PCa or nonaggressive tumors. The objective of this study has been to validate Prostate Health Index (PHI) as a marker of aggressive PCa in one academic institution. PHI was assessed in 357 men scheduled to prostatic biopsy between June of 2013 and July 2014 in one academic institution. Thereafter a subset of 183 men younger than 75 years and total PSA (tPSA) between 3.0 and 10.0 ng/mL, scheduled to it first prostatic biopsy, was retrospectively selected for this study. Twelve cores TRUS guided biopsy, under local anaesthesia, was performed in all cases. Total PSA, free PSA (fPSA), and [-2] proPSA (p2PSA) and prostate volume were determined before the procedure and %fPSA, PSA density (PSAd) and PHI were calculated. Aggressive tumors were considered if any Gleason 4 pattern was found. PHI was compared to %fPSA and PSAd through their ROC curves. Thresholds to detect 90%, 95% of all tumors and 95% and 100% of aggressive tumors were estimated and rates of unnecessary avoided biopsies were calculated and compared. The rate of PCa detection was 37.2% (68) and the rate of aggressive tumors was 24.6% (45). The PHI area under the curve was higher than those of %fPSA and PSAd to detect any PCa (0.749 vs 0.606 and 0.668 respectively) or to detect only aggressive tumors (0.786 vs 0.677 and 0.708 respectively), however, significant differences were not found. The avoided biopsy rates to detect 95% of aggressive tumors were 20.2% for PHI, 14.8% for %fPSA, and 23.5% for PSAd. Even more, to detect all aggressive tumors these rates dropped to 4.9% for PHI, 9.3% for %fPSA, and 7.9% for PSAd. PHI seems a good marker to PCa diagnosis. However, PHI was not superior to %fPSA and PSAd to identify at least 95% of aggressive tumors. Copyright © 2016 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    Oncologic outcomes in men with radiation-recurrent prostate cancer (PCa) treated with salvage radical prostatectomy (SRP) are poorly defined. To identify predictors of biochemical recurrence (BCR), metastasis, and death following SRP to help select patients who may benefit from SRP. This is a retrospective, international, multi-institutional cohort analysis. There was a median follow-up of 4.4 yr following SRP performed on 404 men with radiation-recurrent PCa from 1985 to 2009 in tertiary centers. Open SRP. BCR after SRP was defined as a serum prostate-specific antigen (PSA) ≥ 0.1 or ≥ 0.2 ng/ml (depending on the institution). Secondary end points included progression to metastasis and cancer-specific death. Median age at SRP was 65 yr of age, and median pre-SRP PSA was 4.5 ng/ml. Following SRP, 195 patients experienced BCR, 64 developed metastases, and 40 died from PCa. At 10 yr after SRP, BCR-free survival, metastasis-free survival, and cancer-specific survival (CSS) probabilities were 37% (95% confidence interval [CI], 31-43), 77% (95% CI, 71-82), and 83% (95% CI, 76-88), respectively. On preoperative multivariable analysis, pre-SRP PSA and Gleason score at postradiation prostate biopsy predicted BCR (p = 0.022; global p 75% of patients 10 yr after surgery. Patients with lower pre-SRP PSA levels and lower postradiation prostate biopsy Gleason score have the highest probability of cure from SRP. Copyright © 2011 European Association of Urology.

    National Comprehensive Cancer Network guidelines recommend patients with head and neck cancer (HNC) receive treatment at centers with expertise, but whether provider experience affects survival is unknown. The effect of institutional experience on overall survival (OS) in patients with stage III or IV HNC was investigated within a randomized trial of the Radiation Therapy Oncology Group (RTOG 0129), which compared cisplatin concurrent with standard versus accelerated fractionation radiotherapy. As a surrogate for experience, institutions were classified as historically low- (HLACs) or high-accruing centers (HHACs) based on accrual to 21 RTOG HNC trials (1997 to 2002). The effect of accrual volume on OS was estimated by Cox proportional hazards models. Median RTOG accrual (1997 to 2002) at HLACs was four versus 65 patients at HHACs. Analysis included 471 patients in RTOG 0129 (2002 to 2005) with known human papillomavirus and smoking status. Patients at HLACs versus HHACs had better performance status (0: 62% v 52%; P = .04) and lower T stage (T4: 26.5% v 35.3%; P = .002) but were otherwise similar. Radiotherapy protocol deviations were higher at HLACs versus HHACs (18% v 6%; P accounting for radiotherapy protocol deviations. Institutional experience substantially influences survival in locally advanced HNC. © 2014 by American Society of Clinical Oncology.

    Experience gained at the Royal Marsden Hospital and Institute of Cancer Research has shown that with attention to the design of facilities and procedures and an active personnel monitoring policy, relatively large scale radiation commitments can proceed with individual whole body doses to staff being held well below 15 mSv/annum. In spite of detailed attention to control of radiation work, traumatic radiation incidents may still occur. (H.K.)

    The prevalence of brain metastases (BM) from uterine cancer has recently increased because of the improvement of overall survival (OS) of patients with uterine cancer due to its early detection and improved local control as a result of new effective treatments. However, little information is available regarding their clinical characteristics and prognosis, because oncologists have encountered BM from uterine cancer on rare occasions. Records from 81 patients with uterine BM were collected from 10 institutes in Japan. These were used in a multi-institutional study to identify prognostic factors and develop a graded prognostic assessment (GPA) for patients with BM from uterine cancer. Median OS after the development of BM was 7 months (95% confidence interval, 4 to 10 months). Multivariate analysis revealed that there were survival differences according to the existence of extracranial metastases and number of BM. In the present uterine-GPA, a score of 0 was assigned to those patients with ≥5 BM and extracranial metastasis, a score of 2 was assigned to those patients with one to four BM or without extracranial metastasis, and a score of 4 was assigned to those patients with one to four BM and without extracranial metastasis. The median OS for patients with a uterine-GPA scores of 0, 2, and 4 was 3, 7, and 22 months, respectively. A survival analysis confirmed the presence of statistically significant differences between these groups (p Brain Tumor Registry of Japan. Uterine GPA incorporates two simple clinical parameters of high prognostic significance and can be used to predict the expected survival times in patients with BM from uterine cancer. Its use may help in determining an appropriate treatment for individual patients with BM.

    Pharmacogenetics is a study of possible mechanism by which an individual's response to drugs is genetically determined by variations in their DNA sequence. The aim of pharmacogenetics is to identify the optimal drug and dose for each individual based on their genetic constitution, i.e. to individualize drug treatment. This leads to achieving the maximal therapeutic response for each patient, while reducing adverse side effects of therapy and the cost of treatment. A centralized pharmacogenetics service was formed at the Institute for Oncology and Radiology of Serbia (IORS) with the aim to provide a personalized approach to cancer treatment of Serbian patients. Analyses of KRAS mutations in metastatic colorectal cancer, EGFR mutations in advanced non-small cell lung cancer, CYP2D6 polymorphism in breast cancer, DPD polymorphism in colorectal cancer and MTHFR polymorphism in osteosarcoma have been performed by real time polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (PCR-RFLP). Mutation testing analyses were successful for 1694 KRAS samples and 1821 EGFR samples, while polymorphism testing was successful for 9 CYP2D6 samples, 65 DPD samples and 35 MTHFR samples. Pharmacogenetic methods presented in this paper provide cancer patients in Serbia the best possible choice of treatment at the moment.

    To identify the cancer incidence and mortality in Mexican Social Security Institute beneficiary (MSSI-B) children during 1996-2013. Both cancer cases (n=4 728) and deaths (n=2 378) were analyzed in MSSI-B children who were registered in five states of the Mexican Republic. The incidence and mortality trends and the incidences (rate x 1 000 000 children / year) of the type of cancer, age, sex, and place of residence were obtained. For both indicators (incidence and mortality), there was a downward trend for the period of 1996-2001 and a stable trend for 2002-2013. This occurred in the overall mortality and incidence trends of the Estado de México and Chiapas and in the leukemia and the acute lymphoid subgroups. The annual overall incidence was 128 cases per 1 000 000 children. Leukemia, lymphomas, and central nervous system tumors were the principal cancer groups. Cancer mortality for the period of 2002-2013 did not diminish. Interinstitutional and/or international research should be designed to improve the care of these children.

    To the authors' knowledge, few population-based studies to date have evaluated the association between location of care, complications with induction therapy, and early mortality in patients with acute myeloid leukemia (AML). Using linked data from the California Cancer Registry and Patient Discharge Dataset (1999-2014), the authors identified adult (aged ≥18 years) patients with AML who received inpatient treatment within 30 days of diagnosis. A propensity score was created for treatment at a National Cancer Institute-designated cancer center (NCI-CC). Inverse probability-weighted, multivariable logistic regression models were used to determine associations between location of care, complications, and early mortality (death ≤60 days from diagnosis). Of the 7007 patients with AML, 1762 (25%) were treated at an NCI-CC. Patients with AML who were treated at NCI-CCs were more likely to be aged ≤65 years, live in higher socioeconomic status neighborhoods, have fewer comorbidities, and have public health insurance. Patients treated at NCI-CCs had higher rates of renal failure (23% vs 20%; P = .010) and lower rates of respiratory failure (11% vs 14%; P = .003) and cardiac arrest (1% vs 2%; P = .014). After adjustment for baseline characteristics, treatment at an NCI-CC was associated with lower early mortality (odds ratio, 0.46; 95% confidence interval, 0.38-0.57). The impact of complications on early mortality did not differ by location of care except for higher early mortality noted among patients with respiratory failure treated at non-NCI-CCs. The initial treatment of adult patients with AML at NCI-CCs is associated with a 53% reduction in the odds of early mortality compared with treatment at non-NCI-CCs. Lower early mortality may result from differences in hospital or provider experience and supportive care. Cancer 2018;124:1938-45. © 2018 American Cancer Society. © 2018 American Cancer Society.

    Smoking is a public health problem in Mexico and worldwide; its economic impact on developing countries has not been well documented. The aim of this study was to assess the direct medical costs attributable to smoking incurred by lung cancer patients treated at the National Cancer Institute of Mexico (INCan). The study was conducted at INCan in 2009. We carried out a cost of illness (COI) methodology, using data derived from an expert panel consensus and from medical chart review. A panel of experts developed a diagnostic-therapeutic guide that combined the hospital patient pathways and the infrastructure, human resources, technology, and services provided by the medical units at INCan. Cost estimates in Mexican pesos were adjusted by inflation and converted into US Dollars using the 2013 FIX exchange rate for foreign transactions (1 USD = 13.06 Mexican pesos). A 297 incident cases diagnosed with any type of lung cancer were analyzed. According to clinical stage, the costs per patient were 13,456; 35,648; 106,186; and 144,555 USD, for lung cancer stages I, II, III, and IV respectively. The weighted average annual cost/patient was and 139,801 USD and the average annual cost/patient that was attributable to smoking was 92,269 USD. This cost was independent of the clinical stage, with stage IV representing 96% of the annual cost. The total annual cost of smoking-related lung cancer at INCan was 19,969,781 USD. The medical care costs of lung cancer attributable to smoking represent a high cost both for INCan and the Mexican health sector. These costs could be reduced if all provisions established in the Framework Convention of Tobacco Control of the World Health Organization were implemented in Mexico.

    Most prostate cancer (PCa) patients with a biochemical failure following primary multimodality treatment (surgery and postoperative radiotherapy) relapse in the nodes. To perform a matched-case analysis in men with lymph node recurrent PCa comparing standard of care (SOC) with metastasis-directed therapy (MDT). PCa patients with a prostate-specific antigen (PSA) progression following multimodality treatment were included in this retrospective multi-institutional analysis. The SOC cohort (n=1816) received immediate or delayed androgen deprivation therapy administered at PSA progression. The MDT cohort (n=263) received either salvage lymph node dissection (n=166) or stereotactic body radiotherapy (n=97) at PSA progression to a positron emission tomography-detected nodal recurrence. The primary endpoint, cancer-specific survival (CSS), was analyzed using the Kaplan-Meier method, log-rank test, Cox proportional hazards models, and propensity score-matched analyses. At a median follow-up of 70 (interquartile range: 48-98) mo, MDT was associated with an improved CSS on univariate (p=0.029) and multivariate analysis (hazard ratio: 0.33, 95% confidence interval [CI]: 0.17-0.64) adjusted for the year of radical prostatectomy (RP), age at RP, PSA at RP, time from RP to PSA progression, Gleason score, surgical margin status, pT- and pN-stage. In total, 659 men were matched (3:1 ratio). The 5-yr CSS was 98.6% (95% CI: 94.3-99.6) and 95.7% (95% CI: 93.2-97.3) for MDT and SOC, respectively (p=0.005, log-rank). The main limitations of our study are its retrospective design and lack of standardization of systemic treatment in the SOC cohort. MDT for nodal oligorecurrent PCa improves CSS as compared with SOC. These retrospective data from a multi-institutional pooled analysis should be considered as hypothesis-generating and inform future randomized trials in this setting. Prostate cancer patients experiencing a lymph node recurrence might benefit from local treatments directed at

    Background The aim of this study was to evaluate the chronological changes in epidemiological factors and surgical outcomes in patients with lung cancer who underwent surgery in a single Japanese institution. Patients and methods A clinicopathological database of patients with lung cancer who underwent surgery with curative intent from January 1974 to December 2014 was reviewed. The chronological changes in various factors, including patient’s age, sex, histological type, tumor size, pathological stage (p-stage), surgical method, operative time, intraoperative blood loss, 30-day mortality, and postoperative overall survival (OS), were evaluated. Results A total of 1,616 patients were included. The numbers of resected patients, females, adenocarcinomas, p-stage IA patients, and age at the time of surgery increased with time, but tumor size decreased (all P<0.0001). Concerning surgical methods, the number of sublobar resections increased, but that of pneumonectomies decreased (P<0.0001). The mean operative time, intraoperative blood loss, and the postoperative 30-day mortality rate decreased (all P<0.0001). When the patients were divided into two groups (1974–2004 and 2005–2014), the 5-year OS rates for all patients and for p-stage IA patients improved from 44% to 79% and from 73% to 89%, respectively (all P<0.0001). The best 5-year OS rate was obtained for sublobar resection (73%), followed by lobectomy (60%), combined resection (22%), and pneumonectomy (21%; P<0.0001). Conclusion Changes in epidemiological factors, a trend toward less invasive surgery, and a remarkably improved postoperative OS were confirmed, which demonstrated the increasingly important role of surgery in therapeutic strategies for lung cancer.

    Case-control studies have used a variety of measurements to evaluate the relationship of children's exposure to magnetic fields (50 or 60 Hz) with childhood leukaemia and other childhood cancers. In the absence of knowledge about which exposure metrics may be biologically meaningful, studies during the past 10 years have often used time-weighted average (TWA) summaries of home measurements. Recently, other exposure metrics have been suggested, usually based on theoretical considerations or limited laboratory data. In this paper, the rationale and associated preliminary studies undertaken are described as well as feasibility andvalidity issues governing the choice of the primary magnetic field exposure assessment methods and summary metric used to estimate children's exposure in the National Cancer Institute/Children's Cancer Group (NCI/CCG) case-control study. Also provided are definitions and discussion of the strengths and weaknesses of the various exposure metrics used in exploratory analyses of the NCI/CCG measurement data. Exposure metrics evaluated include measures of central tendency (mean, median, 30th to 70th percentiles), peak exposures (90th and higher percentiles, peak values of the 24 h measurements), and measurements of short-term temporal variability (rate of change). This report describes correlations of the various metrics with the time-weighted average for the 24 h period (TWA-24-h). Most of the metrics were found to be positively and highly correlated with TWA-24-h, but lower correlations of TWA-24-h with peak exposure and with rate of change were observed. To examine further the relation between TWA and alternative metrics, similar exploratory analysis should be considered for existing data sets and for forthcoming measurement investigations of residential magnetic fields and childhood leukaemia.

    High-quality cancer information resources are available but underutilized by the public. Despite greater awareness of the National Cancer Institute's Cancer Information Service among low-income African Americans and Hispanics compared with Caucasians, actual Cancer Information Service usage is lower than expected, paralleling excess cancer-related morbidity and mortality for these subgroups. The proposed research examines how to connect the Cancer Information Service to low-income African-American and Hispanic women and their health care providers. The study will examine whether targeted physician mailing to women scheduled for colposcopy to follow up an abnormal Pap test can increase calls to the Cancer Information Service, enhance appropriate medical follow-up, and improve satisfaction with provider-patient communication. The study will be conducted in two clinics in ethnically diverse low-income communities in Chicago. During the formative phase, patients and providers will provide input regarding materials planned for use in the experimental phase of the study. The experimental phase will use a two-group prospective randomized controlled trial design. African American and Hispanic women with an abnormal Pap test will be randomized to Usual Care (routine colposcopy reminder letter) or Intervention (reminder plus provider recommendation to call the Cancer Information Service and sample questions to ask). Primary outcomes will be: 1) calls to the Cancer Information Service; 2) timely medical follow-up, operationalized by whether the patient keeps her colposcopy appointment within six months of the abnormal Pap; and 3) patient satisfaction with provider-patient communication at follow-up. The study examines the effectiveness of a feasible, sustainable, and culturally sensitive strategy to increase awareness and use of the Cancer Information Service among an underserved population.

    The purpose of this pilot study was to investigate the palliative potential of home-based yoga sessions provided to women with advanced cancer. Personalised 45-minute yoga sessions were offered to three women with advanced cancer by an experienced yoga teacher. Each woman took part in a one-to-one interview after the completion of the yoga programme and was asked to describe her experiences of the programme's impact. The personalised nature of the yoga sessions resulted in similar positive physical and psychosocial effects comparable to those demonstrated in other studies with cancer patients. Participants described physical, mental, and emotional benefits as well as the alleviation of illness impacts. The enhancement of mind-body and body-spirit connections were also noted. Personalised home-based yoga programmes for people with advanced cancer may produce similar benefits, including palliation, as those institutionally-based programmes for people with non-advanced cancer.

    The objectives and strategy of an epidemiological study on the effects of exposure to radon in Norwegian dwellings is presented. The study is a cooperation between the National Institute of Radiation Hygiene and the Norwegian Cancer Registry in Norway and the National Radiological Protection Board of the United Kingdom, with funding by the Norwegian Cancer Society. Measurements of radon are being made in 10,000 dwellings representing all Norwegian municipalities. The potential for detecting an effect of radon exposure by such a study in Norway is unique because: (1) Radon concentrations are high and there are large regional variations. (2) Data from the Norwegian Cancer Registry is of high quality: all cancers have been subject to compulsory reporting since 1955. These data can be broken down according to municipality, sex and age. (3) In 1964/1965 a large scale survey of smoking habits was carried out in Norway. These data can also be broken down according to municipality, sex and age, and by types of smoking and smoking rate. It is intended to examine the correlation between lung cancer incidence and geographical variation in radon levels after making allowance for smoking habits. Radon measurements were started in early 1987 and the results of the study are expected to be published in 1989. (author)

    Before treatment, cancer patients need information about side effects and prognosis, while after treatment they need information to transition to survivorship. Research documenting these needs is limited, especially among racial and ethnic minorities. This study evaluated cancer patients' needs according to race both before and after treatment. We compared white (n = 904) to black (n = 52) patients receiving treatment at 17 National Cancer Institute Community Oncology Research Program (NCORP) sites on their cancer-related concerns and need for information before and after cancer treatment. Two-sample t test and chi-squared analyses were used to assess group differences. Compared to white patients, black patients reported significantly higher concerns about diet (44.3 vs. 25.4 %,) and exercise (40.4 vs. 19.7 %,) during the course of treatment. Compared to whites, blacks also had significantly higher concern about treatment-related issues (white vs. black mean, 25.52 vs. 31.78), self-image issues (7.03 vs. 8.60), family-related issues (10.44 vs. 12.84), and financial concerns (6.42 vs. 8.90, all p < 0.05). Blacks, compared to whites, also had significantly greater post-treatment information needs regarding follow-up tests (8.17 vs. 9.44), stress management (4.12 vs. 4.89), and handling stigma after cancer treatment (4.21 vs. 4.89) [all p < 0.05]. Pre-treatment concerns and post-treatment information needs differed by race, with black patients reporting greater information needs and concerns. In clinical practice, tailored approaches may work particularly well in addressing the needs and concerns of black patients.

    In addition to open surgery, curative therapies for prostate cancer now include endoscopic surgery and radiation therapies. Because of the expansion and subdivision of treatment methods for prostate cancer, the medical fee point schedule in Japan was revised in fiscal year 2006. We examined changes in medical income and expenditure after this revision of the medical fee system. We studied income and expenditure, after institution of the new medical fee schedule, for the five types of therapies for prostate cancer performed at our hospital: two surgical therapies (radical retropubic prostatectomy and laparoscopic prostatectomy) and three radiation therapies (three-dimensional conformal radiation therapy, 192 Ir high-dose-rate brachytherapy, and 125 I low-dose-rate brachytherapy). Low-dose-rate brachytherapy was found to be associated with a profit of 199 yen per patient. Laparoscopic prostatectomy, a highly advanced medical treatment that the fee revision changed from a partially insured to an insured procedure, yielded a profit of 75672 yen per patient. However, high-dose-rate brachytherapy was associated with a loss of 654016 yen per patient. Given the loss in hospital income per patient undergoing high-dose-rate brachytherapy, the medical fee point system for this procedure should be reassessed. (author)

    Full Text Available The Asian Prostate Cancer (A-CaP Study is an Asia-wide initiative that has been developed over the course of 2 years. The study was launched in December 2015 in Tokyo, Japan, and the participating countries and regions engaged in preparations for the study during the course of 2016, including patient registration and creation of databases for the purpose of the study. The Second A-CaP Meeting was held on September 8, 2016 in Seoul, Korea, with the participation of members and collaborators from 12 countries and regions. Under the study, each participating country or region will begin registration of newly diagnosed prostate cancer patients and conduct prognostic investigations. From the data gathered, common research themes will be identified, such as comparisons among Asian countries of background factors in newly diagnosed prostate cancer patients. This is the first Asia-wide study of prostate cancer and has developed from single country research efforts in this field, including in Japan and Korea. At the Second Meeting, participating countries and regions discussed the status of preparations and discussed various issues that are being faced. These issues include technical challenges in creating databases, promoting participation in each country or region, clarifying issues relating to data input, addressing institutional issues such as institutional review board requirements, and the need for dedicated data managers. The meeting was positioned as an opportunity to share information and address outstanding issues prior to the initiation of the study. In addition to A-CaP-specific discussions, a series of special lectures was also delivered as a means of providing international perspectives on the latest developments in prostate cancer and the use of databases and registration studies around the world.

    During the first four decades of the 20th century many oncological organizations and institutions were established in Poland. On 6 June, 1906 the Committee for Cancer Research and Control was founded. After the year 1918 when Poland regained its independence many more cancer control organizations came into being. The organizations created at that time were: the Polish Committee for Cancer Control (Warsaw 1921), the Cancer Control Society of Lódź (Lódź 1927), the Vilnius Committee for Cancer Control (Vilnius 1931), the Polish Cancer Control Institute Association in Lviv (Lviv 1929), the Polish Cancer Control Association (Warsaw 1938). These cancer control organizations undertook multiphase activities (prophylactic, educational, organizational, scientific and research) by creating outpatient and inpatient oncological care institutions, on which base numerous scientific and research papers were produced. The effect of that work was the creation of the Radium Treatment Institute in Lódź and the Research and Therapeutic Institute for Cancer Control in Vilnius, as well as founding oncological hospital wards and clinics. The most important achievement was building and opening the very modern Radium Institute in Warsaw. The initiator of the Institute, which in 1939 had 90 beds on its disposal, was Maria Skłodowska-Curie herself. Cancer control organizations members and activists conducted many propaganda actions on malignant diseases, shared they observations and research findings during meetings, conferences and assemblies in Poland and abroad.

    The literature on metastasis-directed therapy for oligometastatic prostate cancer (PCa) recurrence consists of small heterogeneous studies. This study aimed to reduce the heterogeneity by pooling individual patient data from different institutions treating oligometastatic PCa recurrence with stereotactic body radiotherapy (SBRT). We focussed on patients who were treatment naive, with the aim of determining if SBRT could delay disease progression. We included patients with three or fewer metastases. The Kaplan-Meier method was used to estimate distant progression-free survival (DPFS) and local progression-free survival (LPFS). Toxicity was scored using the Common Terminology Criteria for Adverse Events. In total, 163 metastases were treated in 119 patients. The median DPFS was 21 mo (95% confidence interval, 15-26 mo). A lower radiotherapy dose predicted a higher local recurrence rate with a 3-yr LPFS of 79% for patients treated with a biologically effective dose ≤100Gy versus 99% for patients treated with >100Gy (p=0.01). Seventeen patients (14%) developed toxicity classified as grade 1, and three patients (3%) developed grade 2 toxicity. No grade ≥3 toxicity occurred. These results should serve as a benchmark for future prospective trials. This multi-institutional study pools all of the available data on the use of stereotactic body radiotherapy for limited prostate cancer metastases. We concluded that this approach is safe and associated with a prolonged treatment progression-free survival. Copyright © 2015. Published by Elsevier B.V.

    Full Text Available The uncertainties inherent in clinical measures of prostate cancer (CaP aggressiveness endorse the investigation of clinically validated tissue biomarkers. MUC1 expression has been previously reported to independently predict aggressive localized prostate cancer. We used a large cohort to validate whether MUC1 protein levels measured by immunohistochemistry (IHC predict aggressive cancer, recurrence and survival outcomes after radical prostatectomy independent of clinical and pathological parameters.MUC1 IHC was performed on a multi-institutional tissue microarray (TMA resource including 1,326 men with a median follow-up of 5 years. Associations with clinical and pathological parameters were tested by the Chi-square test and the Wilcoxon rank sum test. Relationships with outcome were assessed with univariable and multivariable Cox proportional hazard models and the Log-rank test.The presence of MUC1 expression was significantly associated with extracapsular extension and higher Gleason score, but not with seminal vesicle invasion, age, positive surgical margins or pre-operative serum PSA levels. In univariable analyses, positive MUC1 staining was significantly associated with a worse recurrence free survival (RFS (HR: 1.24, CI 1.03-1.49, P = 0.02, although not with disease specific survival (DSS, P>0.5. On multivariable analyses, the presence of positive surgical margins, extracapsular extension, seminal vesicle invasion, as well as higher pre-operative PSA and increasing Gleason score were independently associated with RFS, while MUC1 expression was not. Positive MUC1 expression was not independently associated with disease specific survival (DSS, but was weakly associated with overall survival (OS.In our large, rigorously designed validation cohort, MUC1 protein expression was associated with adverse pathological features, although it was not an independent predictor of outcome after radical prostatectomy.

    In Japan, where the mortality rate of prostate cancer is lower than in Western countries, there is little evidence of radiation therapy for prostate cancer. Therefore, we have to refer to the evidence of radiation therapy from Western countries, but we should pay attention to the differences of cultural, racial, or social background between Japan and Western countries. The Patterns of Care Study (PCS) was conducted in Japan and extramural audits were performed for 50 randomly selected institutions. Detailed information of 311 prostate cancer patients without distant metastases and other cancers, who were treated with radiation therapy in 1996-1998, was collected. In this article, the results of PCS for primary prostate cancer were shown, with a review of literature for the appropriate choice of radiation therapy. This study was supported by the Grantin-Aid for Cancer Research from Ministry of Health, Labor and Welfare (10-17). (author)

    This Objective of this study was to see histologic typing of prostate cancer and its relation to patient's age, as no curative therapy exists for the advanced stages. This is a retrospective study of 50 patients suffering from prostatic adenocarcinoma and admitted at Basic Medical Sciences Institute, Jinnah Postgraduate Medical Center Karachi. A total of fifty patients between ages of 50-80 years diagnosed during the period of 1990-2001 suffering from prostate cancer were included in this study. The result showed that maximum number of tumours were in age group ranging from 61-70 years, (58% of total cases). Sixteen were (32%) well-differentiated tumours, twenty-eight (56%), moderately differentiated tumours and six (12%) were labelled as undifferentiated tumours. It was concluded that the majority of tumors were moderately differentiated tumours. Early diagnosis is useful for patients; because high grade tumours have bad prognostic markers. (author)

    To evaluate the pattern of use of androgen deprivation therapy (ADT) with definitive radiotherapy (RT) in men with prostate cancer (PCa) in a population-based study in Australia. This is a prospective cohort of men with intermediate- and high-risk PCa, captured in the population-based Prostate Cancer Outcome Registry Victoria, who were treated with definitive prostate RT between January 2010 and December 2015. The primary outcome of interest was ADT utilization. Chi-squared test for trend was used to evaluate the temporal trend in the use of ADT over the study period. Multivariate logistic regressions were used to evaluate the effects of patient-, tumour- and treatment-related factors, and treatment institutions (public/ private and metropolitan/ regional) on the likelihood of ADT utilization. A total of 1806 men were included in the study, 199 of whom (11%) had favourable National Comprehensive Cancer Network (NCCN) intermediate-risk disease (i.e. only one intermediate-risk feature, primary Gleason grade 3, and variation in the use of ADT between public vs private and metropolitan vs regional institutions. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

    The subjects were 30 multiple primary cancers (out of 2,169 oral squamous cell carcinoma including lip cancers), which were treated at the Division of Head and Neck, Cancer Institute Hospital. Seven synchronous carcinomas and 23 metachronous cases were seen. The most common site of the primary cancer was the tongue. Surgical treatment was performed for the first treatment in 5 cases of the 7 synchronous cancers. On the other hand, radical treatment was performed in 11 cases of the 23 metachronous cancers. Fourteen of the 18 cases were treated by surgical treatment and controlled. It is suggested that surgical treatment is the most effective for oral multiple primary cancers. (author)

    To define subgroups at high risk of local recurrence (LR) after surgery for non-small cell lung cancer using a recursive partitioning analysis (RPA). This Institutional Review Board-approved study included patients who underwent upfront surgery for I-IIIA non-small cell lung cancer at Duke Cancer Institute (primary set) or at other participating institutions (validation set). The 2 data sets were analyzed separately and identically. Disease recurrence at the surgical margin, ipsilateral hilum, and/or mediastinum was considered an LR. Recursive partitioning was used to build regression trees for the prediction of local recurrence-free survival (LRFS) from standard clinical and pathological factors. LRFS distributions were estimated with the Kaplan-Meier method. The 1411 patients in the primary set had a 5-year LRFS rate of 77% (95% confidence interval [CI], 0.74-0.81), and the 889 patients in the validation set had a 5-year LRFS rate of 76% (95% CI, 0.72-0.80). The RPA of the primary data set identified 3 terminal nodes based on stage and histology. These nodes and their 5-year LRFS rates were as follows: (1) stage I/adenocarcinoma, 87% (95% CI, 0.83-0.90); (2) stage I/squamous or large cell, 72% (95% CI, 0.65-0.79); and (3) stage II-IIIA, 62% (95% CI, 0.55-0.69). The validation RPA identified 3 terminal nodes based on lymphovascular invasion (LVI) and stage: (1) no LVI/stage IA, 82% (95% CI, 0.76-0.88); (2) no LVI/stage IB-IIIA, 73% (95% CI, 0.69-0.80); and (3) LVI, 58% (95% CI, 0.47-0.69). The risk of LR was similar in the primary and validation patient data sets. There was discordance between the 2 data sets regarding the clinical factors that best segregate patients into risk groups.

    Multiple observational studies suggest an increased risk of colon cancer in patients with diabetes mellitus (DM). This can theoretically be the result of an influence of the diabetic environment on carcinogenesis or the tumor biologic behavior. To gain insight into the influence of a diabetic environment on colon cancer characteristics and outcomes. Retrospective analysis of clinical records in an academic tertiary care hospital with detailed analysis of 81 diabetic patients diagnosed of colon cancer matched with 79 non-diabetic colon cancer patients. The impact of streptozotocin-induced diabetes on the growth of colon cancer xenografts was studied in mice. The incidence of DM in 1,137 patients with colorectal cancer was 16%. The diabetic colon cancer cases and non-diabetic colon cancer controls were well matched for demographic and clinical variables. The ECOG Scale Performance Status was higher (worse) in diabetics (ECOG ≥1, 29.1% of controls vs 46.9% of diabetics, p = 0.02), but no significant differences were observed in tumor grade, adjuvant therapy, tumor site, lymphovascular invasion, stage, recurrence, death or cancer-related death. Moreover, no differences in tumor variables were observed between patients treated or not with metformin. In the xenograft model, tumor growth and histopathological characteristics did not differ between diabetic and nondiabetic animals. Our findings point towards a mild or negligible effect of the diabetes environment on colon cancer behavior, once cancer has already developed.

    In 2007 the World Cancer Research Fund and American Institute for Cancer Research (WCRF/AICR) report judged that the evidence for an association between red and processed meat consumption and colorectal cancer was convincing. In addition, the effect of other animal products on cancer risk has been studied, and the WCRF/AICR report concluded that milk probably decreases the risk of colorectal cancer but diets high in calcium probably increase the risk of prostate cancer, whereas there was limited evidence for an association between milk and bladder cancer and insufficient evidence for other cancers. There are several potential mechanisms relating meat to cancer, including heterocyclic amines, polycyclic aromatic hydrocarbons, N-nitroso compounds, and heme iron. Although the evidence in favor of a link between red and processed meat and colorectal cancer is convincing, the relations with other cancers are unclear. In this review, we summarize cohort studies conducted by the National Cancer Institute on meat and dairy intake in relation to cancer since the 2007 WCRF/AICR report. We also report the findings of meta-analyses published since 2007. PMID:24847855

    Prostate, breast and colorectal cancer are the most common tumours in Spain. The aim of the present study was to evaluate the association between adherence to nutrition-based guidelines for cancer prevention and prostate, breast and colorectal cancer, in the MCC-Spain case-control study. A total of 1,718 colorectal, 1,343 breast and 864 prostate cancer cases and 3,431 population-based controls recruited between 2007 and 2012, were included in the present study. The World Cancer Research Fund/American Institute for Cancer Research (WCRC/AICR) score based on six recommendations for cancer prevention (on body fatness, physical activity, foods and drinks that promote weight gain, plant foods, animal foods and alcoholic drinks; score range 0-6) was constructed. We used unconditional logistic regression analysis adjusting for potential confounders. One-point increment in the WCRF/AICR score was associated with 25% (95% CI 19-30%) lower risk of colorectal, and 15% (95% CI 7-22%) lower risk of breast cancer; no association with prostate cancer was detected, except for cases with a Gleason score ≥7 (poorly differentiated/undifferentiated tumours) (OR 0.87, 95% CI 0.76-0.99). These results add to the wealth of evidence indicating that a great proportion of common cancer cases could be avoided by adopting healthy lifestyle habits. © 2017 UICC.

    The purpose of this study was to assess the current status of the treatment for oropharyngeal cancer (OPC) in Japan to assist the planning of clinical trials in the future. The data for 523 patients with previously untreated OPC were obtained from 12 institutions from April 2005 to N/larch 2007. Of the 523 patients, 471 patients with squamous cell carcinoma and with curative intent were included in an analysis of the treatment and its results. Of the 471 patients with OPC treated with curative intent, 186 patients (39.5%) were treated with surgery, 118 (25.1%) with radiotherapy (RT) alone and 167 (355%) with CRT. Surgery was indicated for 60.4% of the patients with stage I, 47.8% in stage II, 29.4% in stage III, and 36.44% in stage IV. CRT was indicated for 8.3% in stage II, but the percentage increased with higher stage. The percentage of RT was around 30% among stage I-III, but in stage IV, 21.3% of the patients were indicated for RT. The median follow-up period was 4 years and 5 months. The 2-year and 5-year overall survival rates for the 471 patients were 85% and 69.9%, respectively. The 5-year overall survival rates for patients treated initially with surgery, RT and CRT were 73%, 69.1% and 65.6%, respectively. The 5-year overall survival rates for patients with stage I, II, III, IVA, and IVB were 78.9%. 87.3%, 69.7%, 66.6%, and 47.7%, respectively. Although this study was retrospective, we could understand the tendency of treatment choice according to various factors and treatment results. The information will be useful for planning clinical trials in the future. (author)

    The translation of research evidence into practice is facilitated by clinical trials such as those sponsored by the National Cancer Institute's Community Clinical Oncology Program (CCOP) that help disseminate cancer care innovations to community-based physicians and provider organizations. However, CCOP participation involves unsubsidized costs and organizational challenges that raise concerns about sustained provider participation in clinical trials. This study was designed to improve our understanding of why providers participate in the CCOP in order to inform the decision-making process of administrators, clinicians, organizations, and policy-makers considering CCOP participation. We conducted a multi-site qualitative study of five provider organizations engaged with the CCOP. We interviewed 41 administrative and clinician key informants, asking about what motivated CCOP participation, and what benefits they associated with involvement. We deductively and inductively analyzed verbatim interview transcripts, and explored themes that emerged. Interviewees expressed both "altruistic" and "self-interested" motives for CCOP participation. Altruistic reasons included a desire to increase access to clinical trials and feeling an obligation to patients. Self-interested reasons included the desire to enhance reputation, and a need to integrate disparate cancer care activities. Perceived benefits largely matched expressed motives for CCOP participation, and included internal and external benefits to the organization, and quality of care benefits for both patients and participating physicians. The motives and benefits providers attributed to CCOP participation are consistent with translational research goals, offering evidence that participation can contribute value to providers by expanding access to innovative medical care for patients in need.

    The scope of this article is to identify and analyze the factors that influence the adoption of ICT tools in experiments with bioinformatics at the Brazilian Cancer Institute (INCA). It involves a descriptive and exploratory qualitative field study. Evidence was collected mainly based on in-depth interviews with the management team at the Research Center and the IT Division. The answers were analyzed using the categorical content method. The categories were selected from the scientific literature and consolidated in the Technology-Organization-Environment (TOE) framework created for this study. The model proposed made it possible to demonstrate how the factors selected impacted INCA´s adoption of bioinformatics systems and tools, contributing to the investigation of two critical areas for the development of the health industry in Brazil, namely technological innovation and bioinformatics. Based on the evidence collected, a research question was posed: to what extent can the alignment of the factors related to the adoption of ICT tools in experiments with bioinformatics increase the innovation capacity of a Brazilian biopharmaceutical organization?

    The elderly population in Western countries is growing and constitutes a public health issue. Concomitantly, age-related diseases such as cancer increase. There are few data on the efficacy, tolerability and toxicity of specific anticancer therapy in the very elderly patients; therefore, their management is not standardized. In this bi-institutional study, we reviewed medical records of patients who received or continued specific anticancer therapy beyond the age of 90 years. Geriatric assessment was not reported for our patients. Twelve patients were enrolled. Their general health condition was good, and half of them were living in elderly institutions. Ten patients had a solid tumor and 2 were treated for hematological malignancies. Most were diagnosed with a locally advanced or metastatic disease, and the goal of treatment was curative for only 1 patient. Six patients received chemotherapy as first-line treatment, 4 patients received targeted therapy and 2 received concomitant chemoradiation. Four patients received a second-line treatment. Despite a significant reduction in treatment posology in half of the patients, 8 acute grade 3/4 toxicities were reported and 2 patients died of treatment-related septic shock. Median duration of first-line treatment was 3.2 months, and progression-free survival ranged from 18 to 311 days. Overall survival ranged from 18 days to 11 years. Aging is a heterogeneous process, and management of elderly patients is a multidisciplinary approach. Geriatric assessment helps to identify older patients with a higher risk of morbidity/mortality and allows to assess the risks and benefits of specific anticancer therapy. The choice of treatment should be based primarily on the expected symptomatic benefit, and treatment should not compromise the quality of life. © 2015 S. Karger AG, Basel.

    The aim of this study was to characterize the type and degree of discrepancies between non-expert and expert diagnoses of CNS tumors to identify the value of consultations in surgical neuropathology. Neuropathology experts from 5 National Comprehensive Cancer Network (NCCN) member institutions participated in the review of 1281 consultations selected based on inclusion criteria. The consultation cases were re-reviewed at the NCCN headquarters to determine concordance with the original diagnoses. Among all consultations, 249 (19.4%) were submitted for expert diagnoses without final diagnoses from the submitting institution. Within the remaining 1032 patients, the serious/major discrepancy rate was 4.8%, and less serious and minor discrepancies were seen in 19.4% of the cases. The discrepancy rate was higher among patients who were referred to NCCN institutions for consultation compared to those who were referred for treatment only. The discrepancy rates, patient demographics, type of consultations and submitting institutions varied among participating NCCN institutions. Expert consultations identified a subset of cases with significant diagnostic discrepancies, and constituted the initial diagnoses in some cases. These data indicate that expert consultations in glial tumors and all types of pediatric CNS tumors can improve accurate diagnosis and enable appropriate management. © 2017 American Association of Neuropathologists, Inc.

    Full Text Available Breast cancer in young women is quite uncommon and shows more aggressive characteristics with major disparities between worldwide populations. Prognosis and outcome of breast cancer in young patients are widely studied, but still no consensus is available.We retrospectively included 716 cases of breast cancer women diagnosed in 2009 at the National Institute of Oncology of Rabat. Patients were divided into two groups according to their age: women aged ≤40 years (Group 1 and women aged >40 years (Group 2. Data were recorded from patients' medical files and analyzed using SPSS 13.0 software (IBM.Young patients represent 24.9% of all patients with breast cancer. The comparison between the two groups displayed significant differences regarding nulliparity (p = 0.001 and progesterone receptor negativity (p = 0.01. Moreover, more progression (Metastases/Relapse was registered in young women as compared to older women with breast cancer (p = 0.03. The estimated median follow-up period was 31 months. The 5-years Event-Free Survival (EFS of patients with local disease was 64.6% in young women and 71.5% in older women with breast cancer (p = 0.04. Multivariate analysis in young women showed that nulliparity (HR: 7.2; 95%CI: 1.16-44.54; p = 0.03, T3 tumors (HR: 17.39; 95%CI: 1.74-173.34; p = 0.01 and negative PgR status (HR: 19.85; 95%CI: 1.07-366.54; p = 0.04 can be considered as risk factors for poorer event free survival while hormone therapy was associated with better EFS (HR: 0.11; 95%CI: 0.00-0.75; p = 0.03. In Group 2, multivariate analysis showed that patients with inflammatory breast cancer, N+ status, absence of radiotherapy, absence of chemotherapy, and absence of hormone therapy are at increased risk of recurrence.In Morocco, breast cancer is more frequent in young women as compared to western countries. Breast cancer in young women is more aggressive and is diagnosed late, leading to an intensive treatment. Moreover, the main factors

    Full Text Available A number of international health organizations consider the exposure to residential radon as the second main cause of lung cancer after cigarette smoking. It was found that there is no database on radon concentrations for the Kufa Technical Institute buildings in the literature. This therefore triggers a special need for radon measurement in some Kufa Technical Institute buildings. This study aims to investigate the indoor radon levels inside the Kufa Technical Institute buildings for the first time using different radon measurement methods such as active (RAD-7 and passive (LR-115 Type II methods. Seventy eight of Solid-State Nuclear Track Detectors (SSNTDs LR-115 Type II were distributed at four buildings within the study area. The LR-115 Type II detectors were exposed in the study area for three months period. In parallel to the latter, seventy two active measurements were conducted using RAD-7 in the same buildings for correlation investigation purposes between the two kinds of measurements (i.e. passive and active.The results demonstrate that the radon concentrations were generally low, ranging from 38.4 to 77.2 Bq/m3, with a mean value of 50 Bq/m3. The mean of the equilibrium equivalent radon concentration and annual effective dose were assessed to be 19.9 Bq/m3 and 1.2 mS/y, respectively; the excess lifetime lung cancer risk was approximately 11.6 per million personal. A high correlation was found between the methods of measurements (i.e. LR-115 Type II and RAD-7, R2 = 0.99 which is significant at P < 0.001. The results of this work revealed that the Radon concentration was below the action level set by the United States Environmental Protection Agency of 148 Bq/m3. This therefore indicates that no radiological health hazard exists. However, the relatively high concentrations in some classrooms can be addressed by the natural ventilation or the classrooms being supplied with suction fans.

    To study the relative risk of second cancer after radiotherapy, we reviewed 2465 cases of uterine cervical cancer who were treated in our institute from 1962 to 1986 and were followed up for more than 5 years. Among them, 1502 cases were treated by radiotherapy with or without surgery (radiotherapy group), and the remainder were treated by surgery only (surgery only group). We defined second cancer as malignancy that occurred in another organ after an interval of 5 years or more from the end of treatment of the first cancer. The relative risk of second cancer was computed by the person-year method advocated by Schoenberg. Second cancer was observed among 8 cases of the surgery group, whereas 43 cases were observed among the radiotherapy group. The cases were: rectal cancer, 6 cases; bladder cancer, 4 cases. The observed and expected ratio (O/E ratio) was 4.02 in rectal cancer and 7.98 in bladder cancer. This incidence of the both cancers was significantly high in the radiotherapy group. Three of the 6 cases with rectal cancer underwent operation in our institute. The incubation periods between the first and second cancers were from 9 to 21 years. Each case exhibited symptoms of chronic radiation proctitis after radiotherapy for uterine cervical cancer. It is thought necessary to follow up such cases carefully to detect radiation induced cancer. (author)

    Purpose National Comprehensive Cancer Network guidelines recommend patients with head and neck cancer (HNC) receive treatment at centers with expertise, but whether provider experience affects survival is unknown. Patients and Methods The effect of institutional experience on overall survival (OS) in patients with stage III or IV HNC was investigated within a randomized trial of the Radiation Therapy Oncology Group (RTOG 0129), which compared cisplatin concurrent with standard versus accelerated fractionation radiotherapy. As a surrogate for experience, institutions were classified as historically low- (HLACs) or high-accruing centers (HHACs) based on accrual to 21 RTOG HNC trials (1997 to 2002). The effect of accrual volume on OS was estimated by Cox proportional hazards models. Results Median RTOG accrual (1997 to 2002) at HLACs was four versus 65 patients at HHACs. Analysis included 471 patients in RTOG 0129 (2002 to 2005) with known human papillomavirus and smoking status. Patients at HLACs versus HHACs had better performance status (0: 62% v 52%; P = .04) and lower T stage (T4: 26.5% v 35.3%; P = .002) but were otherwise similar. Radiotherapy protocol deviations were higher at HLACs versus HHACs (18% v 6%; P < .001). When compared with HHACs, patients at HLACs had worse OS (5 years: 51.0% v 69.1%; P = .002). Treatment at HLACs was associated with increased death risk of 91% (hazard ratio [HR], 1.91; 95% CI, 1.37 to 2.65) after adjustment for prognostic factors and 72% (HR, 1.72; 95% CI, 1.23 to 2.40) after radiotherapy compliance adjustment. Conclusion OS is worse for patients with HNC treated at HLACs versus HHACs to cooperative group trials after accounting for radiotherapy protocol deviations. Institutional experience substantially influences survival in locally advanced HNC. PMID:25488965

    There is a clear link between irregular breathing and errors in medical imaging and radiation treatment. The audiovisual biofeedback system is an advanced form of respiratory guidance that has previously demonstrated to facilitate regular patient breathing. The clinical benefits of audiovisual biofeedback will be investigated in an upcoming multi-institutional, randomised, and stratified clinical trial recruiting a total of 75 lung cancer patients undergoing radiation therapy. To comprehensively perform a clinical evaluation of the audiovisual biofeedback system, a multi-institutional study will be performed. Our methodological framework will be based on the widely used Technology Acceptance Model, which gives qualitative scales for two specific variables, perceived usefulness and perceived ease of use, which are fundamental determinants for user acceptance. A total of 75 lung cancer patients will be recruited across seven radiation oncology departments across Australia. Patients will be randomised in a 2:1 ratio, with 2/3 of the patients being recruited into the intervention arm and 1/3 in the control arm. 2:1 randomisation is appropriate as within the interventional arm there is a screening procedure where only patients whose breathing is more regular with audiovisual biofeedback will continue to use this system for their imaging and treatment procedures. Patients within the intervention arm whose free breathing is more regular than audiovisual biofeedback in the screen procedure will remain in the intervention arm of the study but their imaging and treatment procedures will be performed without audiovisual biofeedback. Patients will also be stratified by treating institution and for treatment intent (palliative vs. radical) to ensure similar balance in the arms across the sites. Patients and hospital staff operating the audiovisual biofeedback system will complete questionnaires to assess their experience with audiovisual biofeedback. The objectives of this

    This report describes the formation of the National Cancer Incidence Reporting System in a data base format suitable for computerized record linkage, and the linkage of the data from the Canadian study of cancer following multiple fluoroscopies to that database and to the Canadian National Mortality Data Base between 1940 and 1987. A comprehensive statistical analysis of the breast cancer mortality data occurring among female members of the cohort between 1950 and 1987 with respect to exposure to low-LET radiation is reported, together with a parallel analysis of the breast cancer incidence data between 1975 and 1983. The Canadian fluoroscopy study is a cohort study of tuberculosis patients first treated in Canadian institutions between 1930 and 1952. The present mortality analysis relates to the breast cancer mortality experience between 1950 and 1987. A total of 677 deaths from breast cancer was observed in this period. The most appropriate dose-response relationship appears to be a simple linear one. There is a strong modifying influence of age at first exposure; women first exposed past the age of 30 have little excess risk due to radiation exposure. The breast cancer incidence analysis is based upon 628 cases observed between 1975 and 1983. Again a simple linear model appears to provide an adequate fit to the data. There is a suggestion of time dependency under the additive model, but this is not statistically significant. The results from this latest analysis continue to be reassuring in terms of radiation risk from mammography. (L.L.) 15 refs., figs., tabs

    The aim of this study was to analyze the institutional capacity for provision of women's health care services in Mexico in accordance with prevailing regulations. A probabilistic national sample of health care institutions was used to compare performance rates according to services packages based on analysis of variance. No package showed outstanding performance. Adequate performance was seen in referral and counter-referral centers for uterine cervical cancer, childbirth care, breast cancer diagnosis, family planning counseling, and training in sexual and reproductive health. The lowest performance was seen in the prevention of uterine cervical cancer, obstetric urgencies, family and sexual violence, and promotion of family planning. All the institutions showed low performance in the prevention of breast cancer, promotion of family planning, and management of family and gender violence. The Ministry of Health's leadership needs to be strengthened in order to overcome resistance for the institutions to adhere to the prevailing regulations.

    Introduction Head and neck cancer (HNC) comprises a diverse group of oncological entities, originating from various tissue types and organ localizations, situated in the topographical regions of the head and neck (H&N). This single institution retrospective study was aimed at establishing the HNC patient demographics and categorizing the individual incidence of H&N malignancies, regarding their organ of origin and main histopathological type. Materials and methods All histologically verified cases of HNC from a single tertiary referral center were reviewed in a descriptive retrospective manner. Data sampling period was 47 months. Results Male to female ratio of the registered HNC cases was 3.24:1. The mean age of diagnosis was 63.84 ± 12.65 years, median 65 years. The most common HNC locations include the larynx 30.37% (n = 188), lips and oral cavity 29.08% (n = 180), pharynx 20.03% (n = 124) and salivary glands 10.94% (n = 68), with other locations such as the external nose, nasal cavity and sinuses and auricle and external ear canal harboring a minority of the cases. The main histopathological groups include squamous cell carcinoma 76.74% (n = 475) and adenocarcinoma 6.14% (n = 38), with other malignant entries such as other epithelial malignancies, primary tonsillar, mucosa-associated lymphoid tissue or parenchymal lymphomas, connective tissue neoplasias, neuroendocrine and vascular malignancies diagnosed in a minority of cases. Conclusion Considered to be relatively rare, HNC represents a diverse group of oncological entities with individual and specific demographic characteristics. The reported single institution results appear representative of the national incidence and characteristics of HNC. PMID:28875091

    The National Cancer Institute (NCI) has been at the vanguard of funding tobacco control research for decades with major efforts such as the Community Intervention Trial for Smoking Cessation (COMMIT) in 1988 and the American Stop Smoking Intervention Study (ASSIST) in 1991, followed by the Tobacco Research Initiative for State and Community Interventions in 1999. Most recently, in 2011, the NCI launched the State and Community Tobacco Control (SCTC) Research Initiative to address gaps in secondhand smoke policies, tax and pricing policies, mass media countermeasures, community and social norms and tobacco marketing. The initiative supported large scale research projects and time-sensitive ancillary pilot studies in response to expressed needs of state and community partners. This special issue of Tobacco Control showcases exciting findings from the SCTC. In this introductory article, we provide a brief account of NCI's historical commitment to promoting research to inform tobacco control policy. Published by the BMJ Publishing Group Limited.

    Fifty-five cases of gastric cancer and 14 cases of breast cancer among A-Bomb survivors, which had been treated at Dept. of Surgery, Research Institute for Nuclear Medicine and Biology of Hiroshima Univ., were discussed. Both gastric cancer and breast cancer were recognized more in A-Bomb survivors of advanced age. Particularly, the number of gastric cancer in A-Bomb survivors of over 65-year old was about double the number of unexposed persons. Ratio of male to female in A-Bomb survivors with gastric cancer was 1.6:1, and the ratio of female was higher as compared to the ratio in unexposed persons (2.6:1). Gastric cancer of stage III and IV in A-Bomb survivors was 54.5%, and advanced cancer was comparatively few in A-Bomb survivors as compared to in unexposed persons (78.2%). Similarly, comparatively early stage breast cancer of stage I and II was recognized more in A-Bomb survivors. Particularly, T/sub 1/ and T/sub 2/ in which tumor was small in size showed very high percentage of 92.9% in A-Bomb survivors. In gastric cancer in A-Bomb survivors, poorly differentiated adenocarcinoma showed the highest percentage of 34.5%. However, there was no significant difference according to the exposure conditions. As to histological type of breast cancer, medullary tubular adenocarcinoma abounds mostly in both A-Bomb survivors (71.4%) and unexposed persons (75.9%). As the influence of operation, anemia was recognized before operation strongly in A-Bomb survivors with gastric cancer of over 65-year old. After the operation, transient rise of GOT and GPT was recognized in A-Bomb survivors of advanced age with gastric cancer. However, there was no difference in postoperative complications between A-Bomb survivors and unexposed persons.

    Lip cancer can be treated by surgery, external radiotherapy, and/or brachytherapy (BT). In recent years, BT has become increasingly favored for this type of cancer. The aim of the present study was to analyze local control and survival of patients treated at our institution between July 1989 and June 2008. We performed a retrospective study of 121 patients (109 males and 12 females) who underwent lip cancer brachytherapy from July 1989 to June 2008. Median age was 67 years and median follow-up was 31.8 months (range 20-188 months). Out of 121 patients, 100 (82.6%) were treated with low dose rate (LDR) BT while the remaining 21 patients (17.4%) received high dose rate (HDR) BT. The most common cell type was squamous cell carcinoma (115 cases; 95%) and most tumors were located on the lower lip (107 patients; 88.4%). Most cases were either stage T1 (62 patients; 51.2%), or T2 (44 cases; 36.4%). After 15 years of follow-up, overall survival was 89.5%, cause-specific survival 97.8%, and disease-free survival 86.6%. Local, regional, and distant control at 15 years were 90%, 92%, and 98.8%, respectively. Grade 3 mucosal toxicity was observed in 23% of patients treated with LDR compared to 33% of HDR patients, and grade 4 mucosal toxicity in 9% versus 0% in the HDR group. Our findings confirm that brachytherapy is an effective treatment for lip cancer. The results from our series are in line with those published elsewhere. Based on our limited data, HDR appears to be equally as good as LDR, although this needs to be confirmed by further studies.

    This paper reports on institutional solid waste management in three Tanzanian institutions. It is noted that there are indeed advantages in managing solid waste at institutional level because of the institutions' unique characteristics that also influence their waste management needs. The paper outlines findings from a yearlong study on institutional solid waste management at three institutions: University of Dar es Salaam (UDSM), University College of Lands and Architectural Studies (UCLAS) and Water Resources Institute (WRI). Surveys and field investigations, including on-site waste measurements and questionnaire surveys were done at UDSM, UCLAS and WRI. The study has revealed, among other things, that per capita waste generation rates, W{sub G} vary between staff and students within each institution as well as among the three institutions. The composition of the waste was found to be predominantly organic in nature, suggesting a strong resource recovery potential in terms of animal feed or production of biogas through anaerobic digestion. Additionally, the W{sub G} was found to vary in line with changes in institutional activities like normal studies, examinations and holidays. The study has shown that resource recovery could greatly enhance solid waste management at the case study institutions.

    Breast cancer patients commonly experience sexual concerns, yet rarely discuss them with clinicians. The study examined patient and provider experiences and preferences related to communication about breast cancer-related sexual concerns with the goal of informing intervention development. Patient data (n = 28) were derived from focus groups and interviews with partnered and unpartnered women treated for breast cancer reporting sexual concerns. Provider data (n = 11) came from interviews with breast cancer oncologists and nurse practitioners. Patient and provider data were analyzed separately using the framework method of qualitative analysis. Findings revealed individual and institutional barriers to effective communication about sexual concerns and highlighted key communication facilitators (e.g., a positive patient-provider relationship, patient communication as a driver of provider communication, and vice versa). Patients expressed preferences for open, collaborative communication; providers expressed preferences for focused intervention targets (identifying concerns, offering resources/referrals) and convenient format. A model of effective communication of sexual concerns was developed to inform communication interventions. Findings suggest that to improve patient-provider communication about sexual concerns, knowledge and skills-based interventions that activate patients and that equip providers for effective discussions about sexual concerns are needed, as are institutional changes that could incentivize such discussions.

    Purpose Cancer-Related Fatigue (CRF) negatively affects quality of life among cancer patients. This study seeks to evaluate the outcome and patient receptiveness of a brief counseling program based on National Cancer Institute (NCI) PDQ® information to manage CRF when integrated into Radiation Therapy (RT). Methods We conducted a prospective cohort study among patients undergoing non-palliative RT. Patients with stage I–III tumors and with Karnofsky score 60 or better were given a ten-minute behavioral counseling session during the first two weeks of RT. The Brief Fatigue Inventory (BFI) was administered at baseline/end of RT. Results Of 93 patients enrolled, 89% found the counseling useful and practical. By the end of RT, 59% reported increased exercise, 41.6% sought nutrition counseling, 72.7% prioritized daily activities, 74.4% took daytime naps, and 70.5% talked with other cancer patients. Regarding counseling, patients who had received chemotherapy prior to RT had no change in fatigue (−0.2), those who received RT alone had mild increase in fatigue (0.7, p=0.02), and those who received concurrent chemotherapy experienced a substantial increase in fatigue (3.0 to 5.2, p=0.05). Higher baseline fatigue and receipt of chemotherapy were predictive of worsened fatigue in a multivariate model (both p<0.01). Conclusion Our data suggests that brief behavioral counseling based on NCI guidelines is well accepted by patients showing an uptake in many activities to cope with CRF. Those who receive concurrent chemotherapy and with higher baseline fatigue are at risk for worsening fatigue despite of guideline-based therapy. PMID:29479490

    Neoadjuvant chemoradiotherapy following surgery has recently become a standard therapy. The purpose of the present study was to determine the effectiveness and toxicity of re-irradiation for oligo-recurrence in lymph nodes from esophageal cancer treated by definitive radiotherapy or by surgery with additional radiotherapy. We reviewed retrospectively 248 patients treated with (chemo)radiotherapy for oligo-recurrence in lymph nodes from esophageal cancer in five Japanese high-volume centers between 2000 and 2015. Thirty-three patients in whom re-irradiation was performed were enrolled in this study, and the results for patients in whom re-irradiation was performed were compared with the results for other patients. Median maximum lymph node diameter was 22 mm. Median total radiation dose was 60 Gy. The median calculated biological effective dose using the LQ model with α/β = 10 Gy (BED10) in patients in whom re-irradiation was performed was significantly lower than the median BED10 in others. There was no different factor except for BED10, histology and irradiation field between patients with a past irradiation history and patients without a past irradiation history. The median observation period in surviving patients in whom re-irradiation was performed was 21.7 months. The 3-year overall survival rate in the 33 patients with a past irradiation history was 17.9%, with a median survival period of 16.0 months. Overall survival rate and local control rate in patients with a past irradiation history were significantly worse than those in patients without a past irradiation history (log-rank test, p = 0.016 and p = 0.0007, respectively). One patient in whom re-irradiation was performed died from treatment-related gastric hemorrhage. Results in the present study suggested that re-irradiation for oligo-recurrence in lymph nodes from esophageal cancer treated by definitive radiotherapy or by surgery with additional radiotherapy might be acceptable but

    Aims: To study the differences in the imaging features of spread from the three cancer cell lines, namely epithelial, sarcomatoid, and lymphoid, resulting in peritoneal carcinomatosis, peritoneal sarcomatosis, and peritoneal lymphomatosis, respectively. Materials and methods: In this institutional review board-approved Health Insurance Portability and Accountability Act (HIPAA)-compliant retrospective study, an electronic radiology database was searched to identify patients with peritoneal tumour spread who underwent CT imaging at Dana-Farber Cancer Institute, a tertiary cancer institution, between January 2011 and December 2012. Out of 1214 patients with possible peritoneal tumour spread on the radiology reports, 122 patients were included with histopathologically confirmed peritoneal disease (50 randomly selected patients with peritoneal carcinomatosis and sarcomatosis each, and all 22 patients with lymphomatosis). Two blinded, fellowship-trained radiologists in consensus reviewed the CT images in random order and recorded the imaging findings of peritoneal tumour spread. The statistical analysis was performed in two steps: the first comparing incidence of various features in each group and the second step was a pairwise analysis between each cohort. Results: Peritoneal carcinomatosis more frequently had ascites, peritoneal thickening, and omental cake (all p ≤ 0.001). Measurable nodules were less common in peritoneal carcinomatosis (p < 0.001), and when present, were ill-defined and had an irregular outline (p ≤ 0.002). Peritoneal sarcomatosis more often had discrete nodules that were well defined and had a smooth outline and less frequently had ascites, peritoneal thickening, omental caking, serosal implants, and lymphadenopathy (all p ≤ 0.005). Peritoneal lymphomatosis frequently involved the omentum and mesentery, and often had associated lymphadenopathy and splenomegaly (all p ≤ 0.002). Conclusion: Peritoneal carcinomatosis, sarcomatosis

    To review the relationship between adherence to cancer prevention guidelines published by the American Cancer Society and the World Cancer Research Fund/American Institute for Cancer Research and reductions in cancer incidence, cancer mortality, cardiovascular mortality, and overall mortality. Current cancer prevention guidelines published by the American Cancer Society and the American Institute for Cancer Research, journal articles published between 2004 and 2016, and internet resources. Evidence from a number of large observational studies indicates that following current cancer prevention recommendations in a comprehensive manner results in significant reductions in both cancer risk and cancer mortality, as well as in cardiovascular mortality and overall mortality. Nurses can take the lead in familiarizing patients and families with established cancer prevention recommendations and resources that may assist patients in implementing them comprehensively in their daily lives, as well as in discussing the substantial health benefits of adhering to the recommendations.

    were willing to undergo screening if conducted by the institute. The limitation of this study is small number of subjects; this may not represent the view of nursing staff in general. Large multi-institutional studies have to be undertaken to assess KAP among the nursing staff regarding cancer screening. CONCLUSION This data suggests that levels of knowledge and practice of cancer screening are very poor among nursing staff working in government medical college hospital. Cancer screening program should also include health care professionals in addition to general population.

    Increased risk of ischemic stroke has been validated for several cancers, but limited study evaluated this risk in cervical cancer patients. Our study aimed to evaluate the risk of ischemic stroke in cervical cancer patients. The study analyzed data from the 2003 to 2008 National Health Insurance Research Database (NHIRD) provided by the National Health Research Institutes in Taiwan. Totally, 893 cervical cancer patients after radiotherapy and 1786 appendectomy patients were eligible. The Kaplan-Meier method and the Cox proportional hazards model were used to assess the risk of ischemic stroke. The 5-year cumulative risk of ischemic stroke was significantly higher for the cervical cancer group than for the control group (7.8% vs 5.1%; p <0.005). The risk of stroke was higher in younger (age <51 years) than in older (age ≥51 years) cervical cancer patients (HR = 2.73, p = 0.04; HR = 1.37, p = 0.07) and in patients with more than two comorbid risk factors (5 years cumulative stroke rate of two comorbidities: 15% compared to no comorbidities: 4%). These study demonstrated cervical cancer patients had a higher risk of ischemic stroke than the general population, especially in younger patients. Strategies to reduce this risk should be assessed

    1976-08-01

    The further development of the chemotherapy of cancer in the experimental and clinical fields necessitates a profound knowledge of its chemical, biochemical and pharmacological fundamentals and the mechanism of physiological and pathological growth processes. The 'Arbeitsgemeinschaft Zytostatika' includes chemists, biochemists, pharmacologists, molecular biologists, physicians and immunologists of various scientific institutes and clinics in the Federal Republic of Germany and in West Berlin. It is their aim to carry out basic research as well as clinical-orientated research in the field of the chemotherapy of cancer. In the 15 years of cooperation, fundamental knowledge was gained, especially in the field of the cytotoxic specificity and cancerotoxic selectivity of alkylating cytostatics. New cytostatics with a greater oncostatic selectivity and an altered spectrum of activity were tested and greater knowledge was won on the molecular-biological prerequisites of a rational drug design.

    Full Text Available Introduction: Breast Cancer is one of the most important fatal cancers in women. The mean age of breast cancer in Iran is 48.8 years which is very lower than other countries. Selenium can play an important role in reduction of cancer in several ways, for example selenium increases immunity response and protects cells from oxidation of free radicals and also decreases carcinogenic metabolites. Breast cancer is one of the most important cancers in our country because its incidence is very high and the mean age of patients is very low. Different studies have shown the benefits of selenium in prevention of cancer and since many years selenium has been used as a dietary supplement in advanced countries. Several studies regarding relationship between selenium levels and breast cancer have been done in different countries. We therefore planned a study to evaluate serum selenium levels in breast cancer patients and compare them with a healthy control group. Methods: We selected 45 patients younger than 48 years old and 33 patients older than 48 years old who had not yet received any therapy (surgery, chemotherapy, etc for their cancer as a case group and 46 healthy people who were matched with the patients as a control group and included 23 persons younger and 23 persons older than 48 years old. From each participant, 5cc blood was derived and in several stages, serum selenium levels were evaluated using atomic absorption technology. Data about type of cancer, stage, grade, IHC and cigarette smoking were also collected. Results: The mean Se level was 161.20 μg/l (SD=46.27 μg/l in the patients and 189.13 μg/l (SD=48.75 μg/l in the control group that was statistically significant (P48 years old was 155.39 μg/l (SD=46.68 μg/l that was lower than the control groups. Difference in serum selenium levels between patients and controls in the older group was significant (P=0.007, but in the younger group, it was not statistically significant (P=0

  16. Peer Mentoring at the Uganda Cancer Institute: A Novel Model for Career Development of Clinician-Scientists in Resource-Limited Settings

    2018-03-01

    Full Text Available Cancer centers are beginning to emerge in low- and middle-income countries despite having relatively few oncologists and specialists in related fields. Uganda, like many countries in sub-Saharan Africa, has a cadre of highly motivated clinician-scientists-in-training who are committed to developing the capacity for cancer care and research. However, potential local mentors for these trainees are burdened with uniquely high demands on their time for clinical care, teaching, institutional development, advocacy, and research. Facilitated peer mentoring helps to fill skills and confidence gaps and teaches mentoring skills so that trainees can learn to support one another and regularly access a more senior facilitator/role model. With an added consultant component, programs can engage limited senior faculty time to address specific training needs and to introduce junior investigators to advisors and even potential dyadic mentors. Two years after its inception, our facilitated peer mentoring career development program at the Uganda Cancer Institute in Kampala is successfully developing a new generation of researchers who, in turn, are now providing role models and mentors from within their group. This program provides a practical model for building the next generation of clinical scientists in developing countries.

    The objetive of this study was to explore a bibliometric approach to quantitatively assess current research trends with regard to breast cancer in Mexico. Articles were analyzed by scientific output and research performances of individuals, institutes, and collaborative countries with Mexico. Data were retrieved from the Web of Science database from 2003 to 2012; this was searched using different terms related to breast cancer, including "breast cancer", "mammary ductal carcinoma" and "breast tumour". Data were then extracted from each file, transferred to Excel charts and visualised as diagrams. A total of 256 articles were retrieved. The institutions with the majority of publications were the National Autonomous University of Mexico (22.3%), the National Institute of Cancerology (21.9%), and Social Security Mexican Institute (20.3%); clinical observation studies were the dominant investigation type (64%), and the main types of research were metabolics (24.2%) and pathology (21.5%). This article demonstrates the usefulness of bibliometrics to address key evaluation questions and to establish priorities, define future areas of research, and develop breast cancer control strategies in Mexico.

Compared with 593 (57%) of 1040 lung cancers observed in NLST, 133 (77%) of 172 lung cancers in the PanCan Study were early stage (I or II; p<0·0001). The PanCan model was effective in identifying individuals who were subsequently diagnosed with early, potentially curable, lung cancer. The incidence of cancers detected and the proportion of early stage cancers in the screened population was higher than observed in previous studies. This approach should be considered for adoption in lung cancer screening programmes. Terry Fox Research Institute and Canadian Partnership Against Cancer. Copyright © 2017 Elsevier Ltd.

    Cervical cancer is one of the leading cancers among Indian women with estimated 123,000 new cases and 67,477 deaths in 2012. Cervical cancer is a multi-etiological disease. Factors such as low socioeconomic status, tobacco use, sexual and reproductive factors, HIV and other sexually transmitted diseases and long-term oral contraceptive use have been suggested as determinants. Assessment of socio-demographic profile and reproductive history gives a better picture of the determinants of cervical carcinoma in low-resource settings. This hospital-based cross-sectional study was undertaken at a tertiary healthcare institute at New Delhi, India. Sixty-seven newly diagnosed women with advanced cervical cancer (stage 2B-4B), who were undertaking radio- and/or chemotherapy, were included to assess their socio-demographic, reproductive and clinical profile. The mean age of women at the time of detection of cervical cancer was 52.28 ± 11.29 years (range 30-75 years). More than 60 % of patients were illiterate and belonged to middle socioeconomic status. Thirty-nine percentage of the study subjects had their first sexual experience before 15 years of age. Nearly 54 % women had 5 or more pregnancies. Nearly 73 % of women had all deliveries at home. Majority (69 %) of women had symptoms suggestive of reproductive tract infection. Among them, unusual discharge from vagina (73.13 %) followed by bleeding after menopause (55.10 %) and pain in abdomen (44.77 %) were the most common presenting complaints. Pallor was present in nearly two-third (63.93 %) study subjects. More than half (56.72 %) study subjects had moderate anemia, and 7.46 % had severe anemia before treatment. Mean hemoglobin level of the study subjects was 10.35 ± 1.72 gm% before treatment and 9.69 ± 1.29 gm% after treatment. This difference was statistically significant. Around 97 % of the study subjects had squamous cell carcinoma of the cervix. Majority (53.73 %) of the study subjects were in

    Neoadjuvant chemo-radiotherapy (CRT) followed by surgical resection is the standard treatment for locally advanced rectal cancer, although complete tumor pathological regression is achieved in only up to 30% of cases. A clinicopathological and molecular predictive stratification of patients with advanced rectal cancer is still lacking. Here, c-Met and YKL-40 have been studied as putative predictors of CRT response in rectal cancer, due to their reported involvement in chemoradioresistance in various solid tumors. A multicentric study was designed to assess the role of c-Met and YKL-40 expression in predicting chemoradioresistance and to correlate clinical and pathological features with CRT response. Immunohistochemistry and fluorescent in situ hybridization for c-Met were performed on 81 rectal cancer biopsies from patients with locally advanced rectal adenocarcinoma. All patients underwent standard (50.4 gy in 28 fractions + concurrent capecitabine 825 mg/m2) neoadjuvant CRT or the XELOXART protocol. CRT response was documented on surgical resection specimens and recorded as tumor regression grade (TRG) according to the Mandard criteria. A significant correlation between c-Met and YKL-40 expression was observed (R = 0.43). The expressions of c-Met and YKL-40 were both significantly associated with a lack of complete response (86% and 87% of c-Met and YKL-40 positive cases, prectal cancer. Targeted therapy protocols could take advantage of prior evaluations of c-MET and YKL-40 expression levels to increase therapeutic efficacy.

    Full Text Available Background: There has been an increasing inclination towards minimally invasive esophagectomies (MIEs at our institute recently for resectable oesophageal cancer. Objectives: The purpose of the present study is to report peri-operative and long-term procedure specific outcomes of the two groups and analyse their changing pattern at our institute. Methods: All adult patients with a diagnosis of oesophageal cancer managed at our institute from 2005 to 2015 were included in this retrospective study. Patients' demographic and clinical characteristics were recorded through our hospital information system. The cohort of esophagectomies was allocated into two groups, conventional open esophagectomy (OE or total laparoscopic MIE; hybrid esophagectomies were taken as a separate group. The short-term outcome measures are an operative time in minutes, length of hospital and Intensive Care Unit (ICU stay in days, post-operative complications and 30 days in-hospital mortality. Complications are graded according to the Clavien-Dindo classification system. Long-term outcomes are long-term procedure related complications over a minimum follow-up of 1 year. Trends were analysed by visually inspecting the graphic plots for mean number of events in each group each year. Results: Our results showed no difference in mortality, length of hospital and ICU stays and incidence of major complications between three groups on uni- and multi-variate analysis (P > 0.05. The operative time was significantly longer in MIE group (odds ratio [OR]: 1.66, confidence interval [CI]: 2.4–11.5. The incidence of long-term complication was low for MIE (OR: 1.0, CI: 133–1.017. However, all post-operative surgical outcomes trended to improve in both groups over the course of this study and stayed better for MIE group except for the operative time. Conclusion: MIE has overall comparable surgical outcomes to its conventional counterpart. Furthermore, the peri-operative outcomes tend to

    Four hundred and eighty six previously untreated patients with cancer of the larynx were radically irradiated at the Institute of Oncology in Krakow in the years 1951--1966. Five-year cure rate without cancer symptoms after irradiation as the only treatment was 43% or 209 of 486 cases, and after surgery for recurrent cancer there were in addition, 55 survivors (11%). Dosage schemes of /sup 60/Co therapy for laryngeal tumor have been devised giving a dose of 6,000 rads per 24 fractions in 5 weeks. When irradiating the larynx together with cervical lymph nodes the dose of 6,000 rads was given during 6 to 7 weeks plus further irradiation at a lower dose if necessary. Two techniques of /sup 60/Co irradiation of typical cases of laryngeal cancer are described.

    Purpose: To examine 10-year rates of local, regional, and distant recurrences, patterns of recurrence, and survival rates for breast cancer patients enrolled on Study NRG Oncology/Radiation Therapy Oncology Group 9517, a multi-institutional prospective trial that studied one of the earliest methods of accelerated partial breast irradiation (APBI), multicatheter brachytherapy (MCT). Methods and Materials: Eligibility included stage I/II unifocal breast cancer <3 cm in size after lumpectomy with negative surgical margins and 0 to 3 positive axillary nodes without extracapsular extension. The APBI dose delivered was 34 Gy in 10 twice-daily fractions over 5 days for high-dose-rate (HDR); and 45 Gy in 3.5 to 5 days for low-dose-rate (LDR) brachytherapy. The primary endpoint was HDR and LDR MCT reproducibility. This analysis focuses on long-term ipsilateral breast recurrence (IBR), contralateral breast cancer events (CBE), regional recurrence (RR), and distant metastases (DM), disease-free, and overall survival. Results: The median follow-up was 12.1 years. One hundred patients were accrued from 1997 to 2000; 98 were evaluable; 65 underwent HDR and 33 LDR MCT. Median age was 62 years; 88% had T1 tumors; 81% were pN0. Seventy-seven percent were estrogen receptor and/or progesterone receptor positive; 33% received adjuvant chemotherapy and 64% antiendocrine therapy. There have been 4 isolated IBRs and 1 IBR with RR, for 5.2% 10-year IBR without DM. There was 1 isolated RR, 1 with IBR, and 1 with a CBE, for 3.1% 10-year RR without DM. The 10-year CBE rate was 4.2%, with 5 total events. Eleven patients have developed DM, 8 have died of breast cancer, and 22 have died from other causes. The 10-year DFS and OS rates are 69.8% and 78.0%, respectively. Conclusion: This multi-institutional, phase 2 trial studying MCT-APBI continues to report durable in-breast cancer control rates with long-term follow-up.

    Purpose: To examine 10-year rates of local, regional, and distant recurrences, patterns of recurrence, and survival rates for breast cancer patients enrolled on Study NRG Oncology/Radiation Therapy Oncology Group 9517, a multi-institutional prospective trial that studied one of the earliest methods of accelerated partial breast irradiation (APBI), multicatheter brachytherapy (MCT). Methods and Materials: Eligibility included stage I/II unifocal breast cancer <3 cm in size after lumpectomy with negative surgical margins and 0 to 3 positive axillary nodes without extracapsular extension. The APBI dose delivered was 34 Gy in 10 twice-daily fractions over 5 days for high-dose-rate (HDR); and 45 Gy in 3.5 to 5 days for low-dose-rate (LDR) brachytherapy. The primary endpoint was HDR and LDR MCT reproducibility. This analysis focuses on long-term ipsilateral breast recurrence (IBR), contralateral breast cancer events (CBE), regional recurrence (RR), and distant metastases (DM), disease-free, and overall survival. Results: The median follow-up was 12.1 years. One hundred patients were accrued from 1997 to 2000; 98 were evaluable; 65 underwent HDR and 33 LDR MCT. Median age was 62 years; 88% had T1 tumors; 81% were pN0. Seventy-seven percent were estrogen receptor and/or progesterone receptor positive; 33% received adjuvant chemotherapy and 64% antiendocrine therapy. There have been 4 isolated IBRs and 1 IBR with RR, for 5.2% 10-year IBR without DM. There was 1 isolated RR, 1 with IBR, and 1 with a CBE, for 3.1% 10-year RR without DM. The 10-year CBE rate was 4.2%, with 5 total events. Eleven patients have developed DM, 8 have died of breast cancer, and 22 have died from other causes. The 10-year DFS and OS rates are 69.8% and 78.0%, respectively. Conclusion: This multi-institutional, phase 2 trial studying MCT-APBI continues to report durable in-breast cancer control rates with long-term follow-up.

    The aim of this study was to assess the impact of sunitinib treatment in a non-screened group of patients with metastatic renal cell cancer (mRCC) treated by the Brazilian Unified Health System (SUS) at a single reference institution. Retrospective cohort study, which evaluated patients with mRCC who received sunitinib between May 2010 and December 2013. Fifty-eight patients were eligible. Most patients were male 41 (71%), with a median age of 58 years. Nephrectomy was performed in 41 (71%) patients with a median interval of 16 months between the surgery and initiation of sunitinib. The most prevalent histological subtype was clear cell carcinoma, present in 52 (91.2%) patients. In 50 patients (86%), sunitinib was the first line of systemic treatment. The main adverse effects were fatigue (57%), hypothyroidism (43%), mucositis (33%) and diarrhea (29%). Grade 3 and 4 adverse effects were infrequent: fatigue (12%), hypertension (12%), thrombocytopenia (7%), neutropenia (5%) and hand-foot syndrome (5%). Forty percent of patients achieved a partial response and 35% stable disease, with a disease control rate of 75%. Median progression free survival was 7.6 months and median overall survival was 14.1 months. Sunitinib treatment was active in the majority of patients, especially those with low and intermediate risk by MSKCC score, with manageable toxicity. Survival rates were inferior in this non-screened population with mRCC treated in the SUS. Copyright© by the International Brazilian Journal of Urology.

    This study reports cancer-treating institutions' capacity to deliver comprehensive psychosocial support services. Oncology care providers at 60 cancer-treating institutions completed surveys assessing the capacity of their institutions to provide psychosocial care. Capacity was assessed with the Cancer Psychosocial Care Matrix (CPCM) from the National Cancer Institute (NCI). Scores represented individuals' perceptions of their cancer program's performance with respect to 10 fundamental elements of psychosocial care. Among 2134 respondents, 62% reported a mid-level capacity for ≥5 of 10 CPCM items. In comparison with other types of cancer programs (eg, NCI-designated, academic, or comprehensive centers), providers at community cancer programs reported a significantly greater capacity with respect to patient-provider communication, psychosocial needs assessment, and continuity in the delivery of psychosocial care over time. Nurses and primary medical providers reported a significantly lower capacity for linking patients and families with needed psychosocial services within their respective cancer programs. They also reported a significantly higher capacity for conducting follow-up, re-evaluations, and adjustments of psychosocial treatment plans. Cancer programs are performing moderately well in terms of communicating to patients the importance of psychosocial care, identifying patient psychosocial needs, and referring patients and families to psychosocial services. They are doing less well with respect to the provision of that care over time. Findings suggest that gaps in psychosocial service capacity are a function of patient, provider, and system characteristics. These results may be useful in formulating strategies to enhance psychosocial care delivery. Cancer 2016;122:1937-45. © 2016 American Cancer Society. © 2016 American Cancer Society.

    Introduction: Female germ cell tumors (GCTS) are rare tumors that carry a good prognosis. Aim: To report the experience of the Egyptian National Cancer Institute (ENCI) in managing female GCTs. Methods: This retrospective study included 19 females with ovarian GCTs presenting to the ENCI between 2006 and 2010. Results: The median age was 23 years. Ovaries were the primary site in all patients. Dysgerminoma and teratoma were the predominant pathologies followed by mixed GCT in females. Unilateral ovariectomy or ovarian tumorectomy were the classic surgical procedures with R0 resection being feasible in most cases. Surveillance was adopted in six patients with stage I disease. Chemotherapy was administered in 63% of ovarian GCTs with BEP being the commonest regimen with reasonable tolerability and good response rates. The median OS and EFS were not reached. The projected 5-year OS rate was 93.8%. Both OS and EFS were better in patients responding to chemotherapy than non-responders (p< 0.002). Stage of disease did not significantly affect OS or EFS. Conclusions: Female GCTs rarely affect Egyptian females. They have good prognosis.

Methods: We conducted a retrospective study of COPD prevalence and outcomes among all patients diagnosed with lung cancer at our institution during a 2-year period. Patients with known COPD (group A were compared with those who received a diagnosis of COPD at the time of their oncologic workup (group B. Results: A total of 306 patients were diagnosed with lung cancer during the study period, including 87 with COPD (28.6%. Sixty percent of patients with coexisting lung cancer and COPD were unaware of their obstructive airways disease prior to the lung cancer diagnosis. Patients in group A were older (74+9 vs 69+9 years; P=0.03, had more severe obstruction (% of predicted forced expiratory volume in one second [FEV1%] 55+17 vs 71+13; P=0.04, more emphysema (91% vs 65%; P=0.02, and worse diffusing capacity of the lungs for carbon monoxide 59+19% vs 72+22%; P=0.01 than patients in group B, but the latter had more advanced lung cancer (27.3% vs 13.8% stage IV disease; P=0.01 and consumed more outpatient resources (P=0.03. Overall mortality was similar (56% vs 58%. However, stage-adjusted mortality showed a trend toward greater mortality in group B patients (1.87 [0.91–3.85]; P=0.087. Conclusion: COPD infradiagnosis is common in patients with coexisting lung cancer and is associated with more advanced cancer stage, greater outpatient resource consumption, and may be associated with greater stage-adjusted mortality.

  1. RAS signaling and anti-RAS therapy: lessons learned from genetically engineered mouse models, human cancer cells, and patient-related studies.

    Fang, Bingliang

    2016-01-01

    Activating mutations of oncogenic RAS genes are frequently detected in human cancers. The studies in genetically engineered mouse models (GEMMs) reveal that Kras-activating mutations predispose mice to early onset tumors in the lung, pancreas, and gastrointestinal tract. Nevertheless, most of these tumors do not have metastatic phenotypes. Metastasis occurs when tumors acquire additional genetic changes in other cancer driver genes. Studies on clinical specimens also demonstrated that KRAS mutations are present in premalignant tissues and that most of KRAS mutant human cancers have co-mutations in other cancer driver genes, including TP53, STK11, CDKN2A, and KMT2C in lung cancer; APC, TP53, and PIK3CA in colon cancer; and TP53, CDKN2A, SMAD4, and MED12 in pancreatic cancer. Extensive efforts have been devoted to develop therapeutic agents that target enzymes involved in RAS posttranslational modifications, that inhibit downstream effectors of RAS signaling pathways, and that kill RAS mutant cancer cells through synthetic lethality. Recent clinical studies have revealed that sorafenib, a pan-RAF and VEGFR inhibitor, has impressive benefits for KRAS mutant lung cancer patients. Combination therapy of MEK inhibitors with either docetaxel, AKT inhibitors, or PI3K inhibitors also led to improved clinical responses in some KRAS mutant cancer patients. This review discusses knowledge gained from GEMMs, human cancer cells, and patient-related studies on RAS-mediated tumorigenesis and anti-RAS therapy. Emerging evidence demonstrates that RAS mutant cancers are heterogeneous because of the presence of different mutant alleles and/or co-mutations in other cancer driver genes. Effective subclassifications of RAS mutant cancers may be necessary to improve patients' outcomes through personalized precision medicine. © The Author 2015.

    Cancer care spans the spectrum from screening and diagnosis through therapy and into survivorship. Delivering appropriate care requires patient transitions across multiple specialties, such as primary care, radiology, and oncology. From the program's inception, the National Cancer Institute Community Oncology Research Program (NCORP) sites were tasked with conducting cancer care delivery research (CCDR) that evaluates structural, organizational, and social factors, including care transitions that determine patient outcomes. The aim of this study is to describe the capacity of the NCORP to conduct multidisciplinary CCDR that includes radiology and primary care practices. The NCORP includes 34 community and 12 minority and underserved community sites. The Landscape Capacity Assessment was conducted in 2015 across these 46 sites, composed of the 401 components and subcomponents designated to conduct CCDR. Each respondent had the opportunity to designate an operational practice group, defined as a group of components and subcomponents with common care practices and resources. The primary outcomes were the proportion of adult oncology practice groups with affiliated radiology and primary care practices. The secondary outcomes were the proportion of those affiliated radiology and primary care groups that participate in research. Eighty-seven percent of components and subcomponents responded to at least some portion of the assessment, representing 230 practice groups. Analyzing the 201 adult oncology practice groups, 85% had affiliated radiologists, 69% of whom participate in research. Seventy-nine percent had affiliated primary care practitioners, 31% of whom participate in research. Institutional size, multidisciplinary group practice, and ownership by large regional or multistate health systems was associated with research participation by affiliated radiology and primary care groups. Research participation by these affiliated specialists was not significantly

    In 2009, the NCI launched the Physical Sciences - Oncology Centers (PS-OC) initiative with 12 Centers (U54) funded through 2014. The current phase of the Program includes U54 funded Centers with the added feature of soliciting new Physical Science - Oncology Projects (PS-OP) U01 grant applications through 2017; see NCI PAR-15-021. The PS-OPs, individually and along with other PS-OPs and the Physical Sciences-Oncology Centers (PS-OCs), comprise the Physical Sciences-Oncology Network (PS-ON). The foundation of the Physical Sciences-Oncology initiative is a high-risk, high-reward program that promotes a `physical sciences perspective' of cancer and fosters the convergence of physical science and cancer research by forming transdisciplinary teams of physical scientists (e.g., physicists, mathematicians, chemists, engineers, computer scientists) and cancer researchers (e.g., cancer biologists, oncologists, pathologists) who work closely together to advance our understanding of cancer. The collaborative PS-ON structure catalyzes transformative science through increased exchange of people, ideas, and approaches. PS-ON resources are leveraged to fund Trans-Network pilot projects to enable synergy and cross-testing of experimental and/or theoretical concepts. This session will include a brief PS-ON overview followed by a strategic discussion with the APS community to exchange perspectives on the progression of trans-disciplinary physical sciences in cancer research.

    No cases of lung cancer or mesothelioma have ever been diagnosed or compensated as asbestos-related in Lithuania. This paper attempts to estimate the proportion of those occupationally exposed to asbestos among respiratory cancer patients. Occupational exposure to asbestos was assessed retrospectively for 218 lung cancer and 2 mesothelioma patients admitted to Institute of Oncology, Vilnius University. The evaluation was based on personal interview data using an internationally established questionnaire. Cumulative exposure to asbestos at work was evaluated in fibre-years. A cumulative asbestos exposure of ≥25 fibre-years was found for 7 patients (3.2%), in further 135 (61.2%) a cumulative exposure from 0.01 to 24.99 fibre-years was assessed. The most common occupations among heavily (≥25 fibre-years) exposed patients were smith, welder or insulator in foundries, construction, shipyard as well as asbestos cement and glass industry. Preliminary findings indicate that a fraction (3.2%) of the respiratory cancer cases could be attributed to occupational exposure to asbestos. Since 1560 or more cases of lung cancer are registered every year in Lithuania, about 50 cases per year could be predicted to be asbestos-related. (author)

  5. Imitation Modeling and Institutional Studies

    Maksim Y. Barbashin

    2017-09-01

    Full Text Available This article discusses the use of imitation modeling in the conduct of institutional research. The institutional approach is based on the observation of social behavior. To understand a social process means to determine the key rules that individuals use, undertaking social actions associated with this process or phenomenon. This does not mean that institutions determine behavioral reactions, although there are a number of social situations where the majority of individuals follow the dominant rules. If the main laws of development of the institutional patterns are known, one can describe most of the social processes accurately. The author believes that the main difficulty with the analysis of institutional processes is their recursive nature: from the standards of behavior one may find the proposed actions of social agents who follow, obey or violate institutions, but the possibility of reconstructive analysis is not obvious. The author demonstrates how the institutional approach is applied to the analysis of social behavior. The article describes the basic principles and methodology of imitation modeling. Imitation modeling reveals the importance of institutions in structuring social transactions. The article concludes that in the long term institutional processes are not determined by initial conditions.

    Laparoscopic surgery for rectal cancer is unpopular because it is technically challenging. Suitable training systems have not been widely studied or established despite the steep learning curve for this procedure. We developed a systematic training program that enables resident surgeons to perform laparoscopic low anterior resection (LLAR) for rectal cancer and evaluated the safety and feasibility of this training program. We analyzed prospectively gathered data on all LLARs for rectal cancer performed at a single center over a 7-year period. Patients were assessed for demographic characteristics, tumor characteristics, operative procedure, operative time, blood loss, conversion to open surgery, complications, time to bowel recovery, distal margin, and number of lymph nodes harvested. We compared the early surgical, oncological, and functional outcomes of LLARs performed by expert surgeons with those of LLARs performed by resident surgeons for both intraperitoneal and extraperitoneal rectal cancer. All analyses were performed on an intention-to-treat basis. A total of 137 patients met the inclusion criteria for this study. Of the 75 LLARs for intraperitoneal rectal cancer, 40 were performed by expert surgeons (I-E group) and 35 by resident surgeons (I-R group). Of the 62 LLARs for extraperitoneal rectal cancer, 51 were performed by expert surgeons (E-E group) and 11 by resident surgeons (E-R group). The operative time was longer in the E-R group than in the E-E group. The time to resumption of diet was longer in the I-E group than in the I-R group. The other early outcomes, including blood loss, anastomotic leakage, conversion to open surgery, and number of lymph nodes harvested, were similar in the I-E and I-R groups and in the E-E and E-R groups. Our systematic training program on LLAR for rectal cancer enables resident surgeons to perform this procedure safely early during residency, with acceptable short-term outcomes.

    It is expected that, by 2020, 15 million new cases of cancer will occur every year in the world, one million of them in Africa. Knowledge of cancer trends in African countries is far from adequate, and improvements in cancer prevention efforts are urgently needed. The aim of this study was to characterize breast cancer clinically and pathologically at presentation in Luanda, Angola; we additionally provide quality information that will be useful for breast cancer care planning in the country. Data on breast cancer cases were retrieved from the Angolan Institute of Cancer Control, from 2006 to 2014. For women diagnosed in 2009 (5-years of follow-up), demographic, clinical and pathological information, at presentation, was collected, namely age at diagnosis, parity, methods used for pathological diagnoses, tumor pathological characteristics, stage of disease and treatment. Descriptive statistics were performed. The median age of women diagnosed with breast cancer in 2009 was 47 years old (range 25-89). The most frequent clinical presentation was breast swelling with axillary lymph nodes metastasis (44.9 %), followed by a mass larger than 5 cm (14.2 %) and lump (12.9 %). Invasive ductal carcinoma was the main histologic type (81.8 %). Only 10.1 % of cancer cases had a well differentiated histological grade. Cancers were diagnosed mostly at advanced stages (66.7 % in stage III and 11.1 % in stage IV). In this study, breast cancer was diagnosed at a very advanced stage. Although it reports data from a single cancer center in Luanda, Angola it reinforces the need for early diagnosis and increasing awareness. According to the main challenges related to breast cancer diagnosis and treatment herein presented, we propose a realistic framework that would allow for the implementation of a breast cancer care program, built under a strong network based on cooperation, teaching, audit, good practices and the organization of health services. Angola needs urgently a program for

    The American Cancer Society is fixated on damage control--diagnosis and treatment--and basic molecular biology, with indifference or even hostility to cancer prevention. This myopic mindset is compounded by interlocking conflicts of interest with the cancer drug, mammography, and other industries. The "nonprofit" status of the Society is in sharp conflict with its high overhead and expenses, excessive reserves of assets and contributions to political parties. All attempts to reform the Society over the past two decades have failed; a national economic boycott of the Society is long overdue.

    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 18 F-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)

Aims of the study were to evaluate the needs in cancer inpatients and to improve the understanding of the meanings of the needs expressed. Methods The study was conducted during a "sample day", with all the cancer patients involved having been hospitalized at the Istituto Nazionale Tumori of Milan (INT for at least 48 hours beforehand. The study was carried out using quantitative and qualitative methodologies. The quantitative part of the study consisted in making use of the Needs Evaluation Questionnaire (NEQ, a standardized questionnaire administered by the INT Psychology Unit members, supported by a group of volunteers from the Milan section of the Italian League Against Cancer. The aim of the qualitative part of the study, by semi-structured interviews conducted with a small sample of 8 hospitalized patients, was to improve our understanding of the meanings, implications of the needs directly described from the point of view of the patients. Such an approach determines the reasons and conditions of the dissatisfaction in the patient, and provides additional information for the planning of improvement interventions. Results Of the 224 eligible patients, 182 (81% completed the questionnaire. Four of the top five needs expressed by 40% or more of the responders concerned information needs (diagnosis, future conditions, dialogue with doctors, economic-insurance solutions related to the disease. Only one of the 5 was concerned with improved "hotel" services (bathrooms, meals, cleanliness. Qualitative analysis showed that the most expressed need (to receive more information on their future conditions has the meaning to know how their future life will be affected more than to know his/her actual prognosis. Conclusions Some of the needs which

    Cancer risk is determined by a complex interplay of genetic and environmental factors. Genome-wide association studies (GWAS) have identified hundreds of common (minor allele frequency [MAF] > 0.05) and less common (0.01 Think Tank" on January 10-11, 2012. The objective of the Think Tank was to facilitate discussions on (1) the state of the science, (2) the goals of G × E interaction studies in cancer epidemiology, and (3) opportunities for developing novel study designs and analysis tools. This report summarizes the Think Tank discussion, with a focus on contemporary approaches to the analysis of G × E interactions. Selecting the appropriate methods requires first identifying the relevant scientific question and rationale, with an important distinction made between analyses aiming to characterize the joint effects of putative or established genetic and environmental factors and analyses aiming to discover novel risk factors or novel interaction effects. Other discussion items include measurement error, statistical power, significance, and replication. Additional designs, exposure assessments, and analytical approaches need to be considered as we move from the current small number of success stories to a fuller understanding of the interplay of genetic and environmental factors. © 2013 WILEY PERIODICALS, INC.

    Purpose: Five-year results from the 1989 patterns of care study (PCS) for prostate cancer are now ready for analysis. The PCS was initiated to determine national averages for treatments and examine outcomes prospectively; the 1989 prostate study is the first to have collected pre- and post-treatment serum PSA data. Methods and Materials: Six hundred patients treated with radiotherapy with curative intent for prostate cancer at 71 separate institutions in the year 1989 made up the study population. Three hundred ninety-one cases were fully analyzable. Pretreatment patient and tumor characteristics were as follows: of the 391 analyzable, 255 had pretreatment PSA values obtained, and 245 had a Gleason's sum (GS) reported. Three hundred fifty-eight were Caucasian, 24 African-American, and 3 Hispanic (also 6 unknown). One hundred three patients had PSA 20. Ninety-seven patients were from Radiation Therapy Oncology Group (RTOG), Community Cancer Centers (CCC), or teaching institutions; 141 patients were from other hospital-based, nonteaching institutions; and 153 were from freestanding radiation oncology facilities. Seventy-one patients were T1, 203 T2, and 100 T3/4. Twenty-four out of 391 patients also received neoadjuvant hormone therapy. Survival curves were constructed using Kaplan-Meier methods, and differences between groups were tested for significance using the log-rank test. For cumulative incidence curves, Gray's test was used to investigate failure distributions between groups. The variables entering Cox model for multivariate analysis included age, race, T stage, pretreatment PSA, and GS. A patient was considered a PSA failure if the treating radiation oncologist reported it as such. Results: With a median follow-up of 5.7 years, the 5-year biochemical no evidence of disease (bNED) and overall survival were 56% and 79% respectively for Stage T1, 52% and 81% for T2, and 36% and 63% for Stages T3 and T4 combined.

    Purpose: Knowledge-based Planning (KBP) founded on prior planning experience and Auto-Planning Engine (APE; commercialized in Pinnacle v9.10 TPS) based on progressive optimization algorithm both aim to eliminate the trial-and-error process in radiotherapy inverse planning. This study investigates the performance of the approaches in a multi-institutional setting to evaluate their functionalities in oropharyngeal cancer and offers suggestions how they can be implemented in the clinic. Methods: Radboud University Medical Center (RUMC) provided 35 oropharyngeal cancer patients (SIB-IMRT with two-dose-level prescription: 68 Gy to PTV68 and 50.3 Gy to PTV50.3) with corresponding comparative APE plans. Johns Hopkins University (JHU) contributed to a three-dose-level (70 Gy 63 Gy and 58.1 Gy) plan library for RUMC’s patient KBP generation. MedStar Georgetown University Hospital (MGUH) contributed to a KBP approach employing overlap-volume histogram (OVH-KBP) for generating RUMC’s patient KBP plans using JHU’s plan library. Since both approaches need their own user-defined parameters as initial inputs the first 10 patients were set aside as training set to finalize them. Meanwhile cross-institutional comparisons and adjustments were implemented for investigating institutions’ protocol discrepancies and the approaches’ user-defined parameters were updated accordingly. The finalized parameters were then applied to the remaining 25 patients for OVH-KBP and APE generation. A Wilcoxon rank-sum test was used for statistical comparison with significance level of p<0.05. Results: On average PTV68’s V95 was 96.5% in APE plans vs. 97% in OVH-KBP plans (p=0.36); PTV50.3’s V95 in APE plans was 97.8% vs.97.6% in OVH-KBP plans (p=0.6); cord’s D0.1 cc was 38.6 Gy in OVH-KBP plans vs. 43.7 Gy in APE plans (p=0.0001); mean doses to larynxes oral cavities parotids and submandibular glands were similar with p>0.2. Conclusions: The study demonstrates that KBP and APE can

    An increase in the incidence of thyroid cancer in children has been reported since 1990 in areas of Belarus, Russia and Ukraine which have been highly contaminated during the Chernobyl accident in 1986. A similar increase is now observed in young adults in the same areas. In France, thyroid cancer is characterized by low occurrence and good prognosis. However, the incidence of thyroid cancer has been increasing for more than 20 years, and in 1986, the Chernobyl cloud of radioactive dust crossed the French territory. Thus, the National institute for public health surveillance (I.n.V.S.) carried out several studies to evaluate whether the incidence increase in thyroid cancer is related to radiation exposure from the Chernobyl accident. Since 2000, the I.n.V.S. is in charge of a national multidisciplinary approach involving a wide range of public health actors, including the French network of cancer registries (Francim). Since 2003, the I.n.V.S. has been working on improving the surveillance system according to the actions described in the national cancer plan 2003-2007. The I.n.V.S. has increased its financial contribution to cancer registries including the national registry of solid tumors in children, which was created in 2000. The Institute is also working on the implementation of a multi source system for the national cancer surveillance in link with cancer registries. For the twentieth anniversary of the Chernobyl accident, the I.n.V.S. is publishing updated results from the latest research conducted in close collaboration with the partners. These results do not support the initial hypothesis of a potential 'Chernobyl effect' in France. The increase in the incidence of thyroid cancer is also reported in most of developed countries. Practices in cancer diagnosis and the increased rate of total thyroidectomy for benign lesion may lead pathologists to unexpectedly discover small thyroid tumors. This fact is likely to explain most of the incidence increase. The wide

    Protracted preoperative radio-chemotherapy with a 5-FU-based scheme, or a short course of preoperative radiotherapy without chemotherapy, are the standard neo-adjuvant treatments for resectable stage II-III rectal cancer. Local failure rates are low and reproducible, between 6 and 15% when followed with a 'Total Meso-rectal Excision'. Nevertheless, the therapeutic strategy needs to be improved: distant metastatic recurrence rates remain stable around 30 to 35%, while both sphincter and sexual sequels are still significant. The aim of the present paper was to analyse the ongoing trials listed on the following search engines: the Institut National du Cancer in France, the National Cancer Institute and the National Institute of Health in the United States, and the major cooperative groups. Keywords for the search were: 'rectal cancer', 'preoperative radiotherapy', 'phase II-III', 'preoperative chemotherapy', 'adjuvant chemotherapy' and 'surgery'. Twenty-three trials were selected and classified in different groups, each of them addressing a question of strategy: (1) place of adjuvant chemotherapy; (2) optimization of preoperative radiotherapy; (3) evaluation of new radiosensitization protocols and/or neo-adjuvant chemotherapy; (4) optimization of techniques and timing of surgery; (5) place of radiotherapy for non resectable or metastatic tumors.

    After diagnosis of cancer, many patients show more inclination towards religion and religious activities. This qualitative study using semi-structured interviews explored the perspectives and experiences of 17 Iranian cancer patients and their families regarding the role of religion in their adaptation to cancer in one of the hospitals in Tehran and a charity institute. The content analysis identified two themes: "religious beliefs "(illness as God's will, being cured by God's will, belief in God's supportiveness, having faith in God as a relieving factor, and hope in divine healing) and "relationship with God during the illness." In general, relationship with God and religious beliefs had a positive effect on the patients adapting to their condition, without negative consequences such as stopping their treatment process and just waiting to be cured by God. Thus a strengthening of such beliefs, as a coping factor, could be recommended through religious counseling.

    Breast cancer screening holds a prominent place in public health, health care delivery, policy, and women's health care decisions. Several factors are driving shifts in how population-based breast cancer screening is approached, including advanced imaging technologies, health system performance measures, health care reform, concern for "overdiagnosis," and improved understanding of risk. Maximizing benefits while minimizing the harms of screening requires moving from a "1-size-fits-all" guideline paradigm to more personalized strategies. A refined conceptual model for breast cancer screening is needed to align women's risks and preferences with screening regimens. A conceptual model of personalized breast cancer screening is presented herein that emphasizes key domains and transitions throughout the screening process, as well as multilevel perspectives. The key domains of screening awareness, detection, diagnosis, and treatment and survivorship are conceptualized to function at the level of the patient, provider, facility, health care system, and population/policy arena. Personalized breast cancer screening can be assessed across these domains with both process and outcome measures. Identifying, evaluating, and monitoring process measures in screening is a focus of a National Cancer Institute initiative entitled PROSPR (Population-based Research Optimizing Screening through Personalized Regimens), which will provide generalizable evidence for a risk-based model of breast cancer screening, The model presented builds on prior breast cancer screening models and may serve to identify new measures to optimize benefits-to-harms tradeoffs in population-based screening, which is a timely goal in the era of health care reform. © 2014 American Cancer Society.

    The intensity-modulated radiation therapy (IMRT) planning strategies for nasopharyngeal cancer among Korean radiation oncology facilities were investigated. Five institutions with IMRT planning capacity using the same planning system were invited to participate in this study. The institutions were requested to produce the best plan possible for 2 cases that would deliver 70 Gy to the planning target volume of gross tumor (PTV1), 59.4 Gy to the PTV2, and 51.5 Gy to the PTV3 in which elective irradiation was required. The advised fractionation number was 33. The planning parameters, resultant dose distributions, and biological indices were compared. We found 2-3-fold variations in the volume of treatment targets. Similar degree of variation was found in the delineation of normal tissue. The physician-related factors in IMRT planning had more influence on the plan quality. The inhomogeneity index of PTV dose ranged from 4 to 49% in Case 1, and from 5 to 46% in Case 2. Variation in tumor control probabilities for the primary lesion and involved LNs was less marked. Normal tissue complication probabilities for parotid glands and skin showed marked variation. Results from this study suggest that greater efforts in providing training and continuing education in terms of IMRT planning parameters usually set by physician are necessary for the successful implementation of IMRT.

  1. Are institutional missions aligned with journal-based or document-based disciplinary structures?

    Missions represent the underlying purpose of an institution. These missions can be focused (finding a cure for cancer) or diverse (providing all health services to a local population). They might be aimed at basic research (finding new sub-atomic particles) or very applied (forecasting tomorrow’s weather). Missions can be extremely practical (building i-phones) or abstract (creating maps of scientific inquiry). Our primary focus is on those institutions that are also contributing to society’s knowledge about scientific and technical phenomena. The publications of these institutions are, to some degree, an implicit statement of their mission. Institutions focusing on a cure for cancer will publish articles associated with cancer, while hospitals will publish in a diverse set of medical specialties. Institutions focused on subatomic particles publish in specialized physics journals. While the publication profile of an institution is obviously not the same as an institution’s mission, it is typically consistent with its mission. In this study we analyze the publication profiles of over 4400 institutions using Scopus data to determine if their institutional missions are best explained using a journal-based classification system or a document-based classification system. The structure of this article is as follows. The background section places this work in the context of two streams of research – the accuracies of different document classification systems, and the effect of different national contexts (specifically wealth, health and democracy) on science systems and their impact. We then describe our data and methods before addressing two questions: Do the missions of certain types of institutions align with journal-based or article-based disciplines, and does this vary with national context (wealth, health and democracy). We conclude with a discussion of limitations and possible areas for further investigation. (Author)

    We are reporting the five-year biochemical control, toxicity profile and dosimetric parameters using iodine-125 low dose rate brachytherapy (BT) as monotherapy for early stage prostate cancer at a single institution. Between April 2006 and December 2010, 169 men with early stage prostate cancer were treated with BT. Biochemical failure was defined using the Phoenix definition (nadir + 2 ng/mL). Treatment-related morbidities, including urinary, rectal and sexual function, were measured, applying the International Prostate Symptom Score (IPSS), the 7-grade Quality of Life Scale (QoL) and medical status, the International Consultation on Incontinence Modular Questionnaire (ICIQ), the International Index of Erectile Function (IIEF-5) and the Common Terminology Criteria for Adverse Events (CTCAE v4.03). Seed migration and loss, dosimetric parameters and learning effects were also analyzed. Medium follow-up time was 50 months (range, 1–85 months). The five-year biochemical failure rate was 7%. Acute proctitis rates were 19% (grade 1) and 1% (grade 2), respectively. The overall incidence of incontinence was 19% (mild), 16% (moderate) and < 1% (severe). An increase in IPSS ≥ 5 points was detected in 59% of patients, with 38% regaining their baseline. Seed dislocation was found in 24% of patients and correlated with D90 and V100. A learning curve was found for seed migration, D90 and V100. QoL correlated with the general health condition of patient, incontinence symptoms and IPSS. BT for early stage prostate cancer offers excellent five-year biochemical control with low toxicities. QoL aspects are favorable. A learning curve was detected for procedural aspects but its impact on patient relevant endpoints remains inconclusive

    This study has been conducted primarily to evaluate the leakages radiation in cobalt-60 unit in National Cancer Institute Wad Medani, which represent the basic risky factor in this unit for the radio therapists who spend much time during patient set up, also they need to stand near the head of the machine to fix some accessories. The measurements which done using survey meter give normal level of occupational exposure compared with IAEA references except one situation that the radio therapist to be close contact to the head of unit for long time which may increase the received dose, in this situation. The radio therapist either not well trained, or there is insufficient accessories to reduce the time inside the room. Radiotherapy department need a special considerations from the beginning of construction till starting of treatment. It is important to contain separate rooms, for planning to determine treatment area, another one for molding to shape lead blocks to protect normal parts and an optimum designed room for treatment to enable workers to apply basic radiation protection principles.

    Full Text Available BACKGROUND: Among the more common human malignancies, invasive ductal carcinoma of the pancreas has the worst prognosis. The poor outcome seems to be attributable to difficulty in early detection. METHODS: We compared the plasma protein profiles of 112 pancreatic cancer patients with those of 103 sex- and age-matched healthy controls (Cohort 1 using a newly developed matrix-assisted laser desorption/ionization (oMALDI QqTOF (quadrupole time-of-flight mass spectrometry (MS system. RESULTS: We found that hemi-truncated apolipoprotein AII dimer (ApoAII-2; 17252 m/z, unglycosylated apolipoprotein CIII (ApoCIII-0; 8766 m/z, and their summed value were significantly decreased in the pancreatic cancer patients [P = 1.36×10(-21, P = 4.35×10(-14, and P = 1.83×10(-24 (Mann-Whitney U-test; area-under-curve values of 0.877, 0.798, and 0.903, respectively]. The significance was further validated in a total of 1099 plasma/serum samples, consisting of 2 retrospective cohorts [Cohort 2 (n = 103 and Cohort 3 (n = 163] and a prospective cohort [Cohort 4 (n = 833] collected from 8 medical institutions in Japan and Germany. CONCLUSIONS: We have constructed a robust quantitative MS profiling system and used it to validate alterations of modified apolipoproteins in multiple cohorts of patients with pancreatic cancer.

    Full Text Available Abstract Background Skin Sparing Mastectomy (SSM and immediate breast reconstruction has become increasingly popular as an effective treatment for patients with breast carcinoma. The aim of this study was to evaluate the clinical outcome of skin sparing mastectomy in early breast cancer at a single population-based institution. Methods Records of ninety-five consecutive patients with operable breast cancer who had skin-sparing mastectomy and immediate breast reconstructions between 1995 and 2003 were reviewed. Patient and tumor characteristic, type of reconstruction, postoperative complications, aesthetic results and incidence of recurrence were analyzed. Results Mean age of the patients was 51.6(range 33–72 years. The AJCC pathologic stages were 0 (n = 51, 53.7%, I (n = 20, 21.1%, and II (n = 2, 2.1%. Twenty of the patients had recurrent disease (21.1%. The immediate breast reconstructions were performed with autologus tissue including latissimus dorsi musculocutaneous flap in 63 (66.3% patients and transverse rectus abdominis myocutaneous (TRAM flap in 4 (4.2% patients. Implants were used in 28 (29.4% patients. The average hospital stay was 7.7 days. Flap complication occurred in seven (10.4% patients resulting in four (6% re-operations and there were no delay in accomplishing postoperative adjuvant therapy. At a median follow-up of 69 months (range 48 to 144, local recurrence was seen in one patient (1.1% and systemic recurrence was seen in two patients (2.1%. Conclusion Skin sparing mastectomy and immediate breast reconstruction for early breast cancer is associated with low morbidity and low rate of local recurrence.

    Chromatin organisation affects gene expression and regional mutation frequencies and contributes to carcinogenesis. Aberrant organisation of DNA has been correlated with cancer prognosis in analyses of the chromatin component of tumour cell nuclei using image texture analysis. As yet, the methodology has not been sufficiently validated to permit its clinical application. We aimed to define and validate a novel prognostic biomarker for the automatic detection of heterogeneous chromatin organisation. Machine learning algorithms analysed the chromatin organisation in 461 000 images of tumour cell nuclei stained for DNA from 390 patients (discovery cohort) treated for stage I or II colorectal cancer at the Aker University Hospital (Oslo, Norway). The resulting marker of chromatin heterogeneity, termed Nucleotyping, was subsequently independently validated in six patient cohorts: 442 patients with stage I or II colorectal cancer in the Gloucester Colorectal Cancer Study (UK); 391 patients with stage II colorectal cancer in the QUASAR 2 trial; 246 patients with stage I ovarian carcinoma; 354 patients with uterine sarcoma; 307 patients with prostate carcinoma; and 791 patients with endometrial carcinoma. The primary outcome was cancer-specific survival. In all patient cohorts, patients with chromatin heterogeneous tumours had worse cancer-specific survival than patients with chromatin homogeneous tumours (univariable analysis hazard ratio [HR] 1·7, 95% CI 1·2-2·5, in the discovery cohort; 1·8, 1·0-3·0, in the Gloucester validation cohort; 2·2, 1·1-4·5, in the QUASAR 2 validation cohort; 3·1, 1·9-5·0, in the ovarian carcinoma cohort; 2·5, 1·8-3·4, in the uterine sarcoma cohort; 2·3, 1·2-4·6, in the prostate carcinoma cohort; and 4·3, 2·8-6·8, in the endometrial carcinoma cohort). After adjusting for established prognostic patient characteristics in multivariable analyses, Nucleotyping was prognostic in all cohorts except for the prostate carcinoma

    Growth hormone deficiency (GHD) is the most common endocrine late effect observed in childhood cancer survivors (CCS) previously submitted to cranial irradiation. Radiation therapy can also increase the risk of second neoplasms (SNs). Since in previous studies GH replacement therapy was associated with increased incidence of neoplasia, we explored the association between SNs and GH replacement therapy in a cohort of CCS with GHD. Within the clinical cohort of CCS referred to the Transition Unit for Childhood Cancer Survivors of Turin between November 2001 and December 2012, we considered all patients who developed GHD as a consequence of cancer therapies. GHD was always diagnosed in childhood. To evaluate the quality of data, our cohort was linked to the Childhood Cancer Registry of Piedmont. GHD was diagnosed in 49 out of 310 CCS included in our clinical cohort. At least one SN was diagnosed in 14 patients, meningioma and basal cell carcinoma being the most common SNs. The cumulative incidence of SNs was similar in GH-treated and -untreated patients (8 SNs out of 26 GH-treated and 6 out of 23 GH-untreated patients; p = 0.331). Age, sex and paediatric cancer type had no impact on SNs development. In our CCS, GH replacement therapy does not seem to increase the risk of SNs. Anyway, independently from replacement therapy, in these patients we observed an elevated risk of SNs, possibly related to previous radiation therapy, which suggests the need of a close long-term follow-up.

    Dietary pattern analysis is a powerful technique to study the relationships between diet and cancer, accounting for the specificities of overall dietary intake in each setting. The objective of this study was to quantify the association between dietary patterns and colon and rectum cancers. We evaluated 151 rectum and 102 colon cancer cases selected among surgical patients at the Portuguese Oncology Institute, and 879 community controls. Dietary intake was assessed using a validated food frequency questionnaire. Dietary patterns were defined with principal components and cluster analyses. Age, sex, education, total energy intake, and physical activity-adjusted odds ratios (OR) and 95% confidence intervals (95% CIs) were computed. Three dietary patterns were identified: (i) PI: 'healthy,' high consumption of dairy products, wholegrain cereals, vegetables/salads, legumes, fruits and vegetable soup, and low intake of wine; (ii) PII: 'low consumption of milk and foods containing dietary fiber,' low intake of dairy products, vegetables/salads, legumes, and fruits; and (iii) PIII: 'western,' high consumption of red/processed meat, refined cereals, sugar and sweets, potatoes, alcoholic beverages, and low intake of wholegrain cereals and vegetable soup. Compared with PI, the risk of colon cancer was higher among subjects with PII (OR = 2.07; 95% CI: 1.04-4.14) and PIII (OR = 2.35; 95% CI: 1.19-4.64). The OR estimates for rectum cancer were 3.12 (95% CI: 1.74-5.61) and 1.41 (95% CI: 0.75-2.63), respectively. Our results confirm the higher risk of colorectal cancer among subjects with 'western' diets and 'low consumption of milk and foods containing foods containing dietary fiber'. At a local level, these results support public health messages based on the accumulated evidence on the relationship between individual food items/groups and colorectal cancer.

    Purpose: Proton therapy has been shown to reduce radiation dose to organs at risk (OAR) and could be used to safely escalate the radiation dose. We analyzed outcomes in a group of phase 2 study patients treated with dose-escalated proton therapy with concurrent chemotherapy for stage 3 non-small cell lung cancer (NSCLC). Methods and Materials: From 2009 through 2013, LU02, a phase 2 trial of proton therapy delivering 74 to 80 Gy at 2 Gy/fraction with concurrent chemotherapy for stage 3 NSCLC, was opened to accrual at our institution. Due to slow accrual and competing trials, the study was closed after just 14 patients (stage IIIA, 9 patients; stage IIIB, 5 patients) were accrued over 4 years. During that same time period, 55 additional stage III patients were treated with high-dose proton therapy, including 7 in multi-institutional proton clinical trials, 4 not enrolled due to physician preference, and 44 who were ineligible based on strict entry criteria. An unknown number of patients were ineligible for enrollment due to insurance coverage issues and thus were treated with photon radiation. Median follow-up of surviving patients was 52 months. Results: Two-year overall survival and progression-free survival rates were 57% and 25%, respectively. Median lengths of overall survival and progression-free survival were 33 months and 14 months, respectively. There were no acute grade 3 toxicities related to proton therapy. Late grade 3 gastrointestinal toxicity and pulmonary toxicity each occurred in 1 patient. Conclusions: Dose-escalated proton therapy with concurrent chemotherapy was well tolerated with encouraging results among a small cohort of patients. Unfortunately, single-institution proton studies may be difficult to accrue and consideration for pragmatic and/or multicenter trial design should be considered when developing future proton clinical trials.

    Although the highest burden of Streptococcus agalactiae infections has been reported in industrialized countries, studies on the characterization and epidemiology are still limited in developing countries and implementation of control strategies remains undefined. The aim of this retrospective study was to assess the epidemiological, clinical, and microbiological aspects of S. agalactiae infections in cancer patients treated at a Reference Brazilian National Cancer Institute - INCA, Rio de Janeiro, Brazil. We reviewed the clinical and laboratory records of all cancer patients identified as having invasive S. agalactiae disease during 2010-2014. The isolates were identified by biochemical analysis and tested for antimicrobial susceptibility. A total of 263 strains of S. agalactiae were isolated from cancer patients who had been clinically and microbiologically classified as infected. S. agalactiae infections were mostly detected among adults with solid tumors (94 %) and/or patients who have used indwelling medical devices (77.2 %) or submitted to surgical procedures (71.5 %). Mortality rates (in-hospital mortality during 30 days after the identification of S. agalactiae) related to invasive S. agalactiae infections (n = 28; 31.1 %) for the specific category of neoplasic diseases were: gastrointestinal (46 %), head and neck (25 %), lung (11 %), hematologic (11 %), gynecologic (4 %), and genitourinary (3 %). We also found an increase in S. agalactiae resistance to erythromycin and clindamycin and the emergence of penicillin-less susceptible isolates. A remarkable number of cases of invasive infections due to S. agalactiae strains was identified, mostly in adult patients. Our findings reinforce the need for S. agalactiae control measures in Brazil, including cancer patients.

    Skin cancer constitutes a small but significant proportion of patients with cancer. Although the presence of eumelanin in dark skin is protective against the development of skin cancer, it is increasingly being diagnosed in the Indian population. To study the profile of skin cancer patients presenting to a tertiary hospital in Malwa area of Punjab, India. Retrospective study was done to analyse the profile of skin cancer patients who attended the institution over one year from 1(st) December 2013 to 30(th) November 2014. A comprehensive review of aetiology and related risk factors was done to correlate the environmental factors with high skin cancer prevalence in this region. Skin cancer constituted (3.18%) 84 out of 2638 patients registered with cancer of all types. The age of the patients was 62±14.2 years and ranged from 27 to 92 yrs. Basal cell carcinoma (BCC) was the most common histological type(46/84, 54.76%) followed by squamous cell carcinoma (SCC) (31/84, 36.91%) and malignant melanoma (MM) (7/84, 8.33%). Male: female ratio was found to be 0.79:1. BCC showed higher female preponderance (phistory of prolonged exposure to sunlight. Skin cancer constitutes a small but significant proportion of patients with cancers. This study highlights a paradoxically increasing trend of BCC and female preponderance. Head and neck is the most common site involved. Exposure to Ultra Violet B (UVB) radiation and higher levels of arsenic in drinking water has been reported to be associated with skin cancers. Limited studies show that levels of arsenic and pesticides were higher in the samples of drinking water in Malwa area of Punjab. Therefore a multipronged strategy to provide safe drinking water supply and discouraging the indiscriminate use of pesticides is recommended.

    The prevalence of anxiety and depressive disorders in cancer patients and its associated factors in Pakistan is not known. There is a need to develop an evidence base to help introduce interventions as untreated depression and anxiety can lead to significant morbidity. We assessed the prevalence of depression and anxiety among adult outpatients with and without cancer as well as the effect of various demographic, clinical and behavioral factors on levels of depression and anxiety in cancer patients. This cross-sectional study was carried out in outpatient departments of Multan Institute of Nuclear Medicine and Radiotherapy and Nishtar Medical College Hospital, Multan. Aga Khan University Anxiety and Depression Scale (AKUADS) was used to define the presence of depression and anxiety in study participants. The sample consisted of 150 diagnosed cancer patients and 268 participants without cancer (control group). The mean age of cancer patients was 40.85 years (SD = 16.46) and median illness duration was 5.5 months, while the mean age of the control group was 39.58 years (SD = 11.74). Overall, 66.0% of the cancer patients were found to have depression and anxiety using a cutoff score of 20 on AKUADS. Among the control group, 109 subjects (40.7%) had depression and anxiety. Cancer patients were significantly more likely to suffer from distress compared to the control group (OR = 2.83, 95% CI = 1.89-4.25, P = 0.0001). Performing logistic regression analysis showed that age up to 40 years significantly influenced the prevalence of depression and anxiety in cancer patients. There was no statistically significant difference between gender, marital status, locality, education, income, occupation, physical activity, smoking, cancer site, illness duration and mode of treatment, surgery related to cancer and presence of depression and anxiety. Cancers highly associated with depression and anxiety were gastrointestinal malignancies, chest tumors and breast cancer. This study

    A population of breast cancer patients exists who, for various reasons, never received adjuvant post-operative tamoxifen (TAM). This study was aimed to evaluate the role of late TAM in these patients. From 1997 to 2003, patients aged 35 to 75 years, operated more than 2 years previously for monolateral breast cancer without adjuvant TAM, with no signs of metastases and no contraindication to TAM were randomized to TAM 20 mg/day orally for 2 years or follow-up alone. Events were categorized as locoregional relapse, distant metastases, metachronous breast cancer, tumours other than breast cancer and death from any causes, whichever occurred first. The sample size (197 patients per arm, plus 10% allowance) was based on the assumption of a 30% decrease in the number of events occurring at a rate of 5% annually in the 10 years following randomization. Four hundred and thirty-three patients were randomized in the study (TAM 217, follow-up 216). Patients characteristics (TAM/follow-up) included: median age 55/55 years, median time from surgery 25/25 months (range, 25-288/25-294), in situ carcinoma 18/24, oestrogen receptor (ER) positive in 75/68, negative in 70/57, unknown in 72/91 patients. Previous adjuvant treatment included chemotherapy in 131/120 and an LHRH analogue in 11/13 patients. Thirty-six patients prematurely discontinued TAM after a median of 1 month, mostly because of subjective intolerance. Eighty-three events (TAM 39, follow-up 44) occurred: locoregional relapse in 10/8, distant metastases in 14/16, metachronous breast cancer in 4/10, other tumours in 11/10 patients. Less ER-positive secondary breast cancers occurred in the TAM treated patients than in follow-up patients (1 vs 10, p = 0.005). Event-free survival was similar in both groups of patients. This 5-year analysis revealed significantly less metachronous ER-positive breast cancers in the TAM treated patients. No other statistically significant differences have emerged thus far

    The incidence of ductal carcinoma in situ (DCIS) has increased markedly in recent decades. In the past, mastectomy was the primary treatment for patients with DCIS, but as with invasive cancer, breast-conserving surgery followed by radiation therapy (RT) has become the standard approach. We present the final results of a multi-institutional retrospective study of an Italian Radiation Oncology Group for the study of conservative treatment of DCIS, characterized by a very long period of accrual, from February 1985 to March 2000, and a median follow-up longer than 11 years. A collaborative multi-institutional study was conducted in Italy in 10 Radiation Oncology Departments. A consecutive series of 586 women with DCIS histologically confirmed, treated between February 1985 and March 2000, was retrospectively evaluated. Median age at diagnosis was 55 years (range: 29–84); 32 patients were 40 years old or younger. All women underwent conservative surgery followed by whole breast RT. Irradiation was delivered to the entire breast, for a median total dose of 50 Gy; the tumour bed was boosted in 295 cases (50%) at a median dose of 10 Gy. After a median follow-up of 136 months (range: 16–292 months), 59/586 patients (10%) experienced a local recurrence: invasive in 37 cases, intraductal in 20 and not specified in two. Salvage mastectomy was the treatment of choice in 46 recurrent patients; conservative surgery in 10 and it was unknown in three patients. The incidence of local recurrence was significantly higher in women younger than 40 years (31.3%) (p= 0.0009). Five patients developed distant metastases. Furthermore 40 patients developed a contralateral breast cancer and 31 a second primary tumour in a different site. The 10-year actuarial overall survival (OS) was 95.5% and the 10-year actuarial disease-specific survival (DSS) was 99%. Our results are consistent with those reported in the literature. In particular it has been defined the importance of young age (40

    The patterns of radical radiation therapy for prostate cancer are unclear in Japan. A Patterns of Care Study was performed throughout Japan to examine the patterns of radiation therapy for prostate cancer. From 1999 to 2000, extramural audits were performed on 50 randomly selected institutions (∼7% of all institutions in Japan). Detailed information was collected on a total of 311 prostate cancer patients without evidence of distant metastases, who were treated by radiation therapy between 1996 and 1998. Of these 311 patients, 162 treated radically using photon beams were analyzed in this study. Eighty percent of the patients had high-risk diseases defined as T3 or T4 tumors, a pretreatment prostate-specific antigen level >20 ng/ml or poorly differentiated adenocarcinoma. Androgen ablation was performed in 85.8% of patients and the median duration of hormonal therapy before and after radiation therapy was 5.3 and 21.4 months, respectively. The median total dose of radiation therapy to the prostate was 65.0 Gy (range: 20-74 Gy). The 3-year overall and biochemical relapse-free survival rates were 86.7 and 86.1%, respectively. Late toxicity was mild, with only nine patients (5.6%) exhibiting grade 2 late morbidity. The majority of the patients who received radical radiation therapy in Japan have high-risk disease. Androgen ablation plus radiation therapy was commonly used to treat these patients and resulted in high rates of initial control with a low risk of complications. (author)

    To develop and apply a method to measure in vivo electrical conductivity values using magnetic resonance imaging (MRI) in subjects with breast cancer. A recently developed technique named MREPT (MR electrical properties tomography) together with a novel coil combination process was used to quantify the conductivity values. The overall technique was validated using a phantom study. In addition, 90 subjects were imaged (50 subjects with previously biopsy-confirmed breast tumor and 40 normal subjects), which was approved by our institutional review board (IRB). A routine clinical protocol, specifically a T2 -weighted FSE (fast spin echo) imaging data, was used for reconstruction of conductivity. By employing the coil combination, the relative error in the conductivity map was reduced from ~70% to 10%. The average conductivity values in breast cancers regions (0.89 ± 0.33S/m) was higher compared to parenchymal tissue (0.43 S/m, P conductivity compared to benign cases (0.56 S/m, n = 5) (P conductivity compared to in situ cancers (0.57 S/m) (P conductivity mapping of breast cancers is feasible using a noninvasive in vivo MREPT technique combined with a coil combination process. The method may provide a tool in the MR diagnosis of breast cancer. © 2014 Wiley Periodicals, Inc.

    This prospective cohort study evaluates associations between healthful behaviors consistent with WCRF/AICR cancer prevention guidelines and obesity-related cancer risk, as a third of cancers are estimated to be preventable. The study sample consisted of adults from the Framingham Offspring cohort (n = 2,983). From 1991 to 2008, 480 incident doctor-diagnosed obesity-related cancers were identified. Data on diet, measured by a food frequency questionnaire, anthropometric measures, and self-reported physical activity, collected in 1991 was used to construct a 7-component score based on recommendations for body fatness, physical activity, foods that promote weight gain, plant foods, animal foods, alcohol, and food preservation, processing, and preparation. Multivariable Cox regression models were used to estimate associations between the computed score, its components, and subcomponents in relation to obesity-related cancer risk. The overall score was not associated with obesity-related cancer risk after adjusting for age, sex, smoking, energy, and preexisting conditions (HR 0.94, 95 % CI 0.86-1.02). When score components were evaluated separately, for every unit increment in the alcohol score, there was 29 % lower risk of obesity-related cancers (HR 0.71, 95 % CI 0.51-0.99) and 49-71 % reduced risk of breast, prostate, and colorectal cancers. Every unit increment in the subcomponent score for non-starchy plant foods (fruits, vegetables, and legumes) among participants who consume starchy vegetables was associated with 66 % reduced risk of colorectal cancer (HR 0.44, 95 % CI 0.22-0.88). Lower alcohol consumption and a plant-based diet consistent with the cancer prevention guidelines were associated with reduced risk of obesity-related cancers in this population.

    Full Text Available Given prior evidence that an affected woman conveys a higher risk of ovarian cancer to her sister than to her mother, we hypothesized that there exists an X-linked variant evidenced by transmission to a woman from her paternal grandmother via her father. We ascertained 3,499 grandmother/granddaughter pairs from the Familial Ovarian Cancer Registry at the Roswell Park Cancer Institute observing 892 informative pairs with 157 affected granddaughters. We performed germline X-chromosome exome sequencing on 186 women with ovarian cancer from the registry. The rate of cancers was 28.4% in paternal grandmother/granddaughter pairs and 13.9% in maternal pairs consistent with an X-linked dominant model (Chi-square test X2 = 0.02, p = 0.89 and inconsistent with an autosomal dominant model (X2 = 20.4, p<0.001. Paternal grandmother cases had an earlier age-of-onset versus maternal cases (hazard ratio HR = 1.59, 95%CI: 1.12-2.25 independent of BRCA1/2 status. Reinforcing the X-linked hypothesis, we observed an association between prostate cancer in men and ovarian cancer in his mother and daughters (odds ratio, OR = 2.34, p = 0.034. Unaffected mothers with affected daughters produced significantly more daughters than sons (ratio = 1.96, p<0.005. We performed exome sequencing in reported BRCA negative cases from the registry. Considering age-of-onset, one missense variant (rs176026 in MAGEC3 reached chromosome-wide significance (Hazard ratio HR = 2.85, 95%CI: 1.75-4.65 advancing the age of onset by 6.7 years. In addition to the well-known contribution of BRCA, we demonstrate that a genetic locus on the X-chromosome contributes to ovarian cancer risk. An X-linked pattern of inheritance has implications for genetic risk stratification. Women with an affected paternal grandmother and sisters of affected women are at increased risk for ovarian cancer. Further work is required to validate this variant and to characterize carrier families.

Statistical analysis: Descriptive (mean and percentage), comparative Chi square Test (significance level Pmama and cervix. 20% (CI 0,13-0,28) knew that colon cancer has a genetic predisposition and 58% (CI 0,48-0,67) about mama. 73% (CI 0,63-0,8) received information about cancer prevention. The main source of information was the physician. 46% (CI 0,36-0,55) received medical care in private institutions. Those who had social security, higher educational levels and medical care in private institutions had better knowledge about cancer prevention except in colon cancer. The global results showed levels below 70% in general but extremely low in colon cancer. Not having social security, receiving medical care in public institutions and having a low educational level are related with poor knowledge about cancer prevention except for colon and prostate cancer.

    Full Text Available Background and objective Annual lung screening using spiral computed tomography (CT, has a high sensitivity of detecting early lung cancer (LC, but its high rates of false-positive often lead to unnecessary surgery. The aim of this study is to create a forecasting model of high risk individuals to lung cancer. Methods The pathologic diagnoses of LC in Guangdong Lung Cancer Institute were consecutively chosen as the probands. All the members of the first-degree relatives of probands' and their spouses' were enrolled in this study. These pedigrees consisted of 633 probands' pedigrees and 565 spouses' pedigrees. Unless otherwise stated, analyses were performed using the SPSS 17.0 statistical software package. Results Compared with the control, a family history of carcinoma in first-degree relatives was significantly associated with LC risk (OR=1.71, P<0.001, the sub-group of either one infected individual or more than two infected individuals in first-degree relatives showed significantly statistical differences (P=0.005, P=0.002. In the forecasting model, the risk compared to that in Chinese population was from 0.38 to 63.08 folds. In the population whose risk was more than 10 times to the Chinese population, the accuracy rate of prediction was 88.1%. Conclusion A family history of carcinoma in first-degree relatives was significantly associated with increased LC risk. The more infected individuals exist in first-degree relatives, the more risk was showed. In the forecasting model, smokers especially heavy ones whose risk were more than 10 times to the Chinese population should be receive annual screening. The population are positive at least any two conditions which including male, lung disease history, occupation expose and history of cancer in first-degree relative.

    Introduction The Cervical Cancer (CC) is one of the heavy and costly diseases for the population and the health system. We want to know through this study, the first in Morocco, the annual cost of the treatment of this disease at the National Institute of Oncology (NIO) in Rabat, we also want to explore the possibility of flat-rate management of this disease in order to standardize medical practices and improve reimbursement by health insurance funds. Methods 550 patients were treated for their cervical cancer in the Rabat's NIO. Data of all of medical and surgical services offered to patients were collected from the NIO registry. The cost of care was assessed using the method of micro-costing. We will focus to the total direct cost of all the services lavished to patients in NIO. Results The global cost was about US$ 1,429,673 with an average estimated at US$ 2,599 ± US$ 839. Radiotherapy accounts for 55% of total costs, followed by brachytherapy (27%) and surgery (7%). This three services plus chemotherapy influence the overall cost of care (p <0.001). Other services (radiology, laboratory tests and consultations) represent only 10%. The overall cost is influenced by the stage of the disease, this cost decreased significantly evolving in the stage of CC (p <0.001). Conclusion The standardization of medical practices is essential to the equity and efficiency in access to care. The flat-rate or lump sum by stage of disease is possible and interesting for standardizing medical practices and improving the services of the health insurance plan. PMID:27347298

    The treatment of endometrial cancer (EC) is challenging. There is no standard of care for patients who progressed after carboplatin and paclitaxel (CT) and all available drugs show a small response and poor long-term survival in this scenario. The objective of this study was to evaluate the efficacy and toxicity profile of palliative doxorubicin after progression to CT therapy in advanced or recurrent EC. A retrospective review of the Brazilian National Cancer Institute database between 2009 and 2013 was performed, and all patients with recurrent and advanced EC treated with palliative doxorubicin after progression on CT were included. Progression-free survival (PFS), overall survival (OS), objective response rates as well as toxicity were evaluated. A total of 33 patients were enrolled, with a median age of 65.7 years. Objective responses were documented in 12.1% (3.0% of complete responses and 9.1% of partial responses). The median PFS was 4.4 months, and the median OS was 8.1 months for patients exposed to doxorubicin. The most common adverse event was anemia observed in 60.6% of patients. This retrospective study suggests that doxorubicin has a modest activity in patients with advanced or recurrent EC after treatment with CT.

    Leiomyosarcoma is a rare neoplasm of the head and neck. The purpose of this study was to present our single-institution case series of head and neck leiomyosarcoma and a review of cases in the National Cancer Data Base (NCDB). Patients with head and neck leiomyosarcoma at the University of Pennsylvania and in the NCDB were identified. Demographic characteristics, tumor factors, treatment paradigms, and outcomes were evaluated for prognostic significance. Nine patients with head and neck leiomyosarcoma from the institution were identified; a majority had high-grade disease and cutaneous leiomyosarcoma, with a 5-year survival rate of 50%. Two hundred fifty-nine patients with leiomyosarcoma were found in the NCDB; macroscopic positive margins and high-grade disease were associated with poor prognosis (P < .01), and positive surgical margins were related to adjuvant radiation (P < .001). Head and neck leiomyosarcoma presents at a high grade and is preferentially treated with surgery. Several demographic and tumor-specific factors are associated with outcomes and prognosis. © 2017 Wiley Periodicals, Inc.

    Full Text Available The article is devoted to the neo-institutional approach as a methodological basis in the study of electronic government. In this article substantiates the choice of neo-institutional approach to the study of the processes of implementation of information and communication technologies in the activity of state institutions, analyzes the differences of neoinstitutionalism from traditional institutional approach, considers the features of the different directions of neo-institutionalism, namely sociological, historical and rational choice theory. Attention is paid to the reasons for the renewed interest in political institutions in political science. The article emphasizes the importance of considering the electronic government as an institution, and the conditions for its implementation in the Russian political system as the institutional environment. The authors pay special attention to the variety of sociological neo-institutionalism, used, in addition to political science in sociology of organizations. The article substantiates the value of using sociological institutionalism to explore the electronic government based on a comparative analysis of e-government projects in Russia and abroad and explores its heuristic capabilities. It examines the impact of the system of norms and values of the institutional environment on the processes of formation and development of electronic government in Russia. The research capacity of this theory is due to the fact that it allows us to trace the reasons for copying and replication of inefficient practices and organizational and management schemes, to identify the factors impeding innovation use by the state of electronic interaction technologies. It is emphasized that the use of the theory of institutional isomorphism is useful in the sphere of implementation of electronic technologies, in which a key role play pluralism, horizontal managerial communication, inter-agency coordination.

    Full Text Available The aim of the study: to analyze the risk of lung cancer caused by exposure to indoor radon using an environmental study, taking into account recent data on the possible effect of Human Papillomavirus, based on lung cancer mortality and radon exposure in the Russian regions.Materials and methods: in the analysis, linear dependencies of lung cancer against influencing factors were used. The average radon concentration for the regions of Russia was earlier reconstructed on the basis of the annual reports of the form 4-DOZ. Information on morbidity and mortality from malignant neoplasms in Russia was obtained from annual reports issued by the Р. Hertsen Moscow Oncology Research Institute. As a surrogate of the level of infection with Human Papillomavirus, the incidence of cervix cancer was used. The smoking prevalence was estimated applying data on the incidence of tongue cancer.Results: taking into account smoking and infection with Human Papillomavirus, it is possible to obtain estimates of lung cancer excess relative risk when induced by radon in dwellings consistent with the results of case-control studies.Conclusion: the analysis of regionally aggregated data on deaths from lung cancer in Russia, the average level of indoor radon concentrations and significant risk factors for lung cancer confirms the linear threshold-free concept of radiation-induced carcinogenesis.

    Primary or neoadjuvant chemotherapy prior to definitive local therapy has potential advantages for locally advanced cervix cancer. It can down stage a cancer and allow definitive local therapy to be technically possible (surgery), or potentially more effective (radiotherapy). It can also eradicate subclinical systemic metastases. This report reviews a single institution's experience of neoadjuvant chemotherapy prior to definitive local therapy for cervix cancer over a 13-year period. One hundred and six patients were treated with this intent. The patients were analysed for their response to chemotherapy, treatment received, survival, relapse and toxicity. The chemotherapy was feasible and the majority of patients had a complete or partial response (58.5%). Eight patients did not proceed to local treatment. Forty-six patients had definitive surgery and 52 had definitive radiotherapy. The 5-year overall survival was 27% and the majority of patients died with disease. The first site of relapse was usually in the pelvis (46.2%). Late complications that required ongoing medical therapy (n = 6) or surgical intervention (n = 2) were recorded in eight patients (7.5%). On univariate analysis stage (P= 0.04), tumour size (P = 0.01), lymph node status (P=0.003), response to chemotherapy (P = 0.045) and treatment (P = 0.003) were all significant predictors of survival. On multivariate analysis, tumour size (P < 0.0001) and nodal status (P = 0.02) were significant predictors of survival. Despite the impressive responses to chemotherapy of advanced cervix cancer, there is evidence from randomized trials that it does not improve or compromise survival prior to radiotherapy. As its role prior to surgery remains unclear, it should not be used in this setting outside a prospective randomized trial. Copyright (2001) Blackwell Science Pty Ltd

    Despite the widespread use of 5-HT3 receptor antagonist antiemetics such as ondansetron and granistron, up to 70% of patients with cancer receiving highly emetogenic chemotherapy agents experience postchemotherapy nausea and vomiting. Delayed postchemotherapy nausea (nausea that occurs >/= 24 hours after chemotherapy administration) and anticipatory nausea (nausea that develops before chemotherapy administration, in anticipation of it) are poorly controlled by currently available antiemetic agents. Scientific studies suggest that ginger (Zingiber officinale) might have beneficial effects on nausea and vomiting associated with motion sickness, surgery, and pregnancy. In 2 small studies of patients with cancer receiving chemotherapy, addition of ginger to standard antiemetic medication further reduced the severity of postchemotherapy nausea. This article describes a phase II/III randomized, dose-finding, placebo-controlled, double-blind clinical trial to assess the efficacy of ginger for nausea associated with chemotherapy for cancer. The study is currently being conducted by private practice oncology groups that are funded by the National Cancer Institute's Community Clinical Oncology Program and affiliated with the University of Rochester Cancer Center Community Clinical Oncology Program Research Base.

    Although 3D image based brachytherapy is currently the standard of treatment in cervical cancer, most of the centres in developing countries still practice orthogonal intracavitary brachytherapy due to financial constraints. The quest for optimum dose and fractionation schedule in high dose rate (HDR) intracavitary brachytherapy (ICBT) is still ongoing. While the American Brachytherapy Society recommends four to eight fractions of each less than 7.5 Gy, there are some studies demonstrating similar efficacy and comparable toxicity with higher doses per fraction. To assess the treatment efficacy and late complications of HDR ICBT with 9 Gy per fraction in two fractions. This is a prospective institutional study in Southern India carried on from 1st June 2012 to 31st July 2014. In this period, 76 patients of cervical cancer satisfying our inclusion criteria were treated with concurrent chemo-radiation following ICBT with 9 Gy per fraction in two fractions, five to seven days apart. The median follow-up period in the study was 24 months (range 10.6 - 31.2 months). The 2 year actuarial local control rate, disease-free survival and overall survival were 88.1%, 84.2% and 81.8% respectively. Although 38.2% patients suffered from late toxicity, only 3 patients had grade III late toxicity. In our experience, HDR brachytherapy with 9 Gy per fraction in two fractions is an effective dose fractionation for the treatment of cervical cancer with acceptable toxicity.

    As a cause of death in females, cancer of the uterus is one of the important cancers in Japan. In 1962 it was responsible for 15.5% of all the deaths due to cancer in women and ranked next to the proportion attributed to cancer of the stomach. The JNIH-ABCC Life Span Study of A-bomb survivors also shows that cancer of the stomach and uterus were the major causes of cancer deaths in the female population. The present study, which was carried out in 1963, was begun in the hope of elucidating some of the relationships of the factors other than radiation possibly associated with the incidence of cancer of the uterus in the Life Span Study (ST 100) sample in Horoshima. Environmental factors considered to play a role in the development of uterine cancer were studied by interview with a close relative of the subject. The data did not clearly support the findings reported elsewhere that residential history, occupational history, history of marital status, smoking and alcohol drinking habits, and socioeconomic factors were associated with the incidence of cancer of the uterus. A brief analysis was also conducted for the accuracy of death certificates. The results suggest that an epidemiologic study should be conducted on morbidity data derived from pathologic findings and a revised plan is desirable to elucidate the factors associated with the incidence of cancer of the uterus using the various recent experimental findings as references. 124 references, 15 tables.

    Purpose: To report late gastrointestinal (GI) and genitourinary (GU) toxicity, biochemical and clinical outcomes, and overall survival after hypofractionated radiation therapy for prostate cancer (PC). Methods and Materials: Three institutions included 113 patients with T1 to T3N0M0 PC in a phase II study. Patients were treated with 56 Gy in 16 fractions over 4 weeks. Late toxicity was scored using Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer criteria extended with additional symptoms. Biochemical outcome was reported according to the Phoenix definition for biochemical failure. Results: The incidence of late GI and GU toxicity was low. The 3-year actuarial risk of developing late GU and GI toxicity of grade {>=}2 was 13% and 8% respectively. Five-year biochemical non-evidence of disease (bNED) was 94%. Risk group, T stage, and deviation from planned hormone treatment were significant predictive factors for bNED. Deviation from hormone treatment remained significant in multivariate analysis. Five-year clinical non evidence of disease and overall survival was 95% and 91% respectively. No patient died from PC. Conclusions: Hypofractionated high-dose radiation therapy is a valuable treatment option for patients with PC, with excellent biochemical and clinical outcome and low toxicity.

Prospective observational hospital based study that enrolled breast cancer patients from catchment area of an oncology service hospital in Nigeria between 2007 and 2013. Patients' demographics, breast cancer burden and health care giver presentation variables were analysed for causal factors of seeking medical help and what determines commencement of effective oncological treatment. Forty-six patients were enrolled, 19.6% of them presented primarily to oncologist while 80.4% presented secondarily for oncological treatment. There is a significant difference in presentation time for oncological treatment (t = -3.56, df = 42.90, p = 0.001) between primary (M =11.56 ± 5.21 weeks) and secondary presentation (M= 52.56 ± 10.27weeks). Tumor burden of those that presented secondarily were significantly more advanced (U = 78.5, p = 0.011) and, univariate analysis reveals that: patients' matrimonial setting, breast cancer awareness and mode of discovery of breast symptoms are patient related factors that determines their choice of health care providers and, determinant of effective oncological treatment is patient first contact health care provider. Patients' bio-characteristics that determine their choice of health care provider should be incorporated into community breast cancer sensitization drives.

    Aim: To investigate the yield of imaging in patients with relapsed prostate cancer (PC) with a low trigger prostate-specific antigen (PSA). Materials and methods: This institutional review board (IRB)-approved, Health Insurance Portability and Accountability Act (HIPAA)-compliant retrospective study included all 133 patients (mean age 68 years; range 45–88; median 69 months since original diagnosis; interquartile range [IQR]: 32–139) with hormone-sensitive PC (HSPC, n=28) or castration-resistant PC (CRPC, n=105) and trigger PSA 0.05 for all). Fifty-seven of the 133 (43%) patients had findings seen only at CT, of which 37 had new extra-osseous findings. Only 2/133 (2%) had findings at bone scintigraphy not seen at CT, both in areas not covered on CT. Conclusion: Imaging frequently demonstrated new metastatic and non-metastatic findings in patients with a low trigger PSA. CT is valuable in these patients because extra-osseous findings not visible at bone scintigraphy are frequently seen. - Highlights: • New and existing metastases common in prostate cancer with low trigger PSA. • Previous reports of threshold PSA levels may not apply in follow-up setting. • No difference in metastatic pattern between hormone sensitive and resistant disease. • CT showed extra-osseous findings not seen on bone scan in 44% patients. • Bone scan rarely showed findings not visible on concurrent CT.

    The objective of this study was to investigate the incidence of skeletal-related events (SRE) in urological cancer patients with bone metastases in Japan. Five hundred eleven patients with urological cancer and documented bone metastases treated from January 2003 to April 2008 in ten Japanese institutions were included in a retrospective analysis. Type and incidence of SRE (fracture, radiotherapy, spinal cord compression, surgery, hypercalcemia, and bone pain) were determined from patient medical records. The overall incidence of SRE, including 'pain', was 61%. The most common event was radiotherapy for bone metastases, with an incidence of 31%. The overall incidence of events seemed to be similar among Japanese and Western patients with prostate cancer and renal cell carcinoma when comparing data with previously published reports. Nevertheless, a much lower incidence of fracture (19.1%) was observed in Japanese renal cell carcinoma patients. The overall incidence of SRE in Japanese urological cancer patients with bone metastasis was similar to that in Western patients, but the incidence of fracture was lower in Japanese renal cancer patients.

    Adolescents with cancer have had less improvement in survival than other populations in the United States. This may be due, in part, to adolescents not receiving treatment at Children's Oncology Group (COG) institutions, which have been shown to increase survival for some cancers. The objective of this ecologic study was to examine geographic distance to COG institutions and adolescent cancer mortality. We calculated cancer mortality among adolescents and sociodemographic and healthcare access factors in four geographic zones at selected distances surrounding COG facilities: Zone A (area within 10 miles of any COG institution), Zones B and C (concentric rings with distances from a COG institution of >10-25 miles and >25-50 miles, respectively), and Zone D (area outside of 50 miles). The adolescent cancer death rate was highest in Zone A at 3.21 deaths/100,000, followed by Zone B at 3.05 deaths/100,000, Zone C at 2.94 deaths/100,000, and Zone D at 2.88 deaths/100,000. The United States-wide death rate for whites without Hispanic ethnicity, blacks without Hispanic ethnicity, and persons with Hispanic ethnicity was 2.96 deaths/100,000, 3.10 deaths/100,000, and 3.26 deaths/100,000, respectively. Zone A had high levels of poverty (15%), no health insurance coverage (16%), and no vehicle access (16%). Geographic access to COG institutions, as measured by distance alone, played no evident role in death rate differences across zones. Among adolescents, socioeconomic factors, such as poverty and health insurance coverage, may have a greater impact on cancer mortality than geographic distance to COG institution.

    A survey based on a questionnaire to urologists in Kyushu and Okinawa areas was carried out to assess the current status of first-line therapy for elderly patients with prostate cancer. Ninety-three urologists from 93 institutes answered the questionnaire. Endocrine therapy is widely performed as first-line therapy for elderly patients with prostate cancer. They mostly receive immediate-continuous therapy regardless of their clinical factors. Only 8 (9%) and 7 (8%) institutes have the options of deferred and intermittent therapy, respectively. LH-RH analogue and non-steroidal anti-androgens are commonly used. Chemoendocrine therapy is performed in 33 (35%) institutes for selected patients. Estramustine and 5-fluorouracil (5-FU) derivatives are commonly used as chemotherapeutic agents. Sixty (65%) institutes do not have this modality as a treatment option. Risks arising from the treatment and quality of life (QOL) disturbance are the main reasons for this. Radiation therapy and radical prostatectomy are performed in 53 (57%) and 47 (51%) institutes, respectively, for selected patients with loco-regional disease. However, 22 (24%) institutes do not have these definitive therapies as treatment options. QOL and risks arising from the treatments are the main factors for selecting definitive or non-definitive therapy. In elderly patients with prostate cancer, cancer control is not always the goal of treatment. QOL within a relatively shorter life expectancy is an important factor for decision making in the management of these patients. (authors)

    Delays in diagnosis due to low Breast Cancer awareness are widespread in Brazil maybe owing to ineffective strategies to raise attention on early diagnosis. As a proxy of collective interest in BC screanning (BCS) we studied the monthly accesses to BC and BCS webpages in INCA's website along 48 months. A log analyzer built a time serie (2006-2009) of BC and BCS monthly means, which oscilations were studied by analysis of variance (ANOVA). We found significant increasing accesses to BC and transient "attention peaks". Enlargement in BC/BCS differences along all period were caused by increasing accesses to BC and decreasing/minor/stable oscillations to SBC pages. These results are consistent with previous reports on increasing interest to BC contrasting with indifference on BCS. In the context of an exploratory study, we discussed some aspects: weakness of a "prevention culture"; lack of confidence in health system and screening programs; "celebrity effect" in the context of media framing; collective perception of risks heightened by perception of social vulnerability. Findings suggest that culture-tailored communication strategies would be necessary to inform Brazilian people about BCS. Future research is needed to study social perceptions and constructions on BC topics.

    Like that of other Asian countries gastric cancer (GC) is also a leading cancer in Bangladesh and also a cause for cancer-related mortality. Infection with Helicobacter pylori ( H. pylori ) is the strongest recognized risk factor for gastric adenocarcinoma. The infection is also prevalent in common people. This case-control study was carried out to find an association between GC and H. pylori infection in the community. To evaluate association of H. pylori and carcinoma of stomach this study was conducted at National Institute of Cancer Research & Hospital, Dhaka from January 2013 to December 2014. H. pylori status was determined serologically by using H. pylori kit in the department of Biochemistry laboratory of Bangabandhu Sheikh Mujib Medical University. In total, 114 patients with GC and 520 patients not having GC were studied as controls. Logistic regression method was used to calculate the odds ratio. Significantly more patients in the case group (86.8%) were found to be seropositive for H. pylori antigen in contrast to the control group (67.5%). All of the cases in the present study were in advanced stage. No significant association between H. pylori seropositivity and tumor location was found. It was noted that undifferentiated gastric carcinoma had slightly more association with H. pylori infection. Younger H. pylori -infected patients had been found to be at higher relative risk for GC than older patients. As there is a strong association found between GC and H. pylori infection special emphasis to eradicate H. pylori infection might reduce the incidence of this dreadly disease.

    Although family history of testicular cancer is well-established as a risk factor for testicular cancer, it is unknown whether family history of ovarian cancer is associated with risk of testicular cancer. Using data from the Familial Ovarian Cancer Registry on 2636 families with multiple cases of ovarian cancer, we systematically compared relative frequencies of ovarian cancer among relatives of men with testicular and non-testicular cancers. Thirty-one families with cases of both ovarian and testicular cancer were identified. We observed that, among men with cancer, those with testicular cancer were more likely to have a mother with ovarian cancer than those with non-testicular cancers (OR = 3.32, p = 0.004). Zero paternal grandmothers of men with testicular cancer had ovarian cancer. These observations provide compelling preliminary evidence for a familial association between ovarian and testicular cancers Future studies should be designed to further investigate this association and evaluate X-linkage.

    This study, funded by the National Cancer Institute, assessed cancer awareness and service needs in the Republic of the Marshall Islands (RMI). Findings suggest that cancer is the second-leading cause of death in the RMI and is, in part, a consequence of 12 years of nuclear testing in this region of the Pacific. However, cancer-related services are lacking. Assistance is needed to establish a national cancer registry, to increase public awareness about cancer and related risk factors, and to develop and implement a cancer prevention and screening program.

In this pilot study, we evaluated field cancerization using nano-ALA and methyl aminolevulinate (MAL, the latter being commercialized as Metvix®.Methods and results: Photodynamic therapy was used for the treatment of patients with selected skin lesions, whereas the fluorescence of the corresponding photosensitizer was used to evaluate the time evolution of field cancerization in a quantitative way. Field cancerization was quantified using newly developed color image segmentation software. Using photodynamic therapy as the precancer skin treatment and the approach introduced herein for evaluation of fluorescent area, we found that the half-life of field cancerization reduction was 43.3 days and 34.3 days for nano-ALA and MAL, respectively. We also found that nano-ALA targeted about 45% more skin lesion areas than MAL. Further, we found the mean reduction in area of skin field cancerization was about 10% greater for nano-ALA than for MAL.Conclusion: Although preliminary, our findings indicate that the efficacy of nano-ALA in

    A history of periodontal disease and the presence of circulating antibodies to selected oral pathogens have been associated with increased risk of pancreatic cancer; however, direct relationships of oral microbes with pancreatic cancer have not been evaluated in prospective studies. We examine the relationship of oral microbiota with subsequent risk of pancreatic cancer in a large nested case-control study. We selected 361 incident adenocarcinoma of pancreas and 371 matched controls from two prospective cohort studies, the American Cancer Society Cancer Prevention Study II and the National Cancer Institute Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. From pre-diagnostic oral wash samples, we characterised the composition of the oral microbiota using bacterial 16S ribosomal RNA (16S rRNA) gene sequencing. The associations between oral microbiota and risk of pancreatic cancer, controlling for the random effect of cohorts and other covariates, were examined using traditional and L1-penalised least absolute shrinkage and selection operator logistic regression. Carriage of oral pathogens, Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans , were associated with higher risk of pancreatic cancer (adjusted OR for presence vs absence=1.60 and 95% CI 1.15 to 2.22; OR=2.20 and 95% CI 1.16 to 4.18, respectively). Phylum Fusobacteria and its genus Leptotrichia were associated with decreased pancreatic cancer risk (OR per per cent increase of relative abundance=0.94 and 95% CI 0.89 to 0.99; OR=0.87 and 95% CI 0.79 to 0.95, respectively). Risks related to these phylotypes remained after exclusion of cases that developed within 2 years of sample collection, reducing the likelihood of reverse causation in this prospective study. This study provides supportive evidence that oral microbiota may play a role in the aetiology of pancreatic cancer. Published by the BMJ Publishing Group Limited.

    Background Radiotherapy (RT) or concurrent chemoradiation therapy has been suggested to increase the risk of coronary heart disease for cervical cancer patients, but the results of studies have been inconsistent. Therefore, we aimed to investigate the factors which influence the risk of developing myocardial infarction (MI) in cervical cancer patients with a large, nationwide cohort. Methods The study analyzed data from the 1996 to 2010 National Health Insurance Research Database provided by the National Health Research Institutes in Taiwan. The assessed number of patients with cervical cancer with radiotherapy only, surgery with bilateral oophorectomy only, and with appendectomy were 308, 323 and 229, respectively. The Kaplan-Meier method and the Cox proportional hazards model were used to assess the risk of myocardial infarction. Results The adjusted hazard ratio for cervical cancer in patients with MI was 1.97 (95% CI, 0.97 - 3.91; P = 0.05) for the group that received RT alone, and 2.13 (95% CI, 1.11 - 3.75; P = 0.01) for the surgery group when compared with controls. The more risk comorbidities they have, the higher the risk of myocardial infarction would be for the patients. Conclusion The incidence of MI was significantly higher among cervical cancer patients with RT alone or surgery with bilateral oophorectomy alone than among general populations. RT might be as a factor to increase risk as bilateral oophorectomy. Whether RT itself triggers menopause or impairs the ovarian hormone production that increases the risk of MI needs to be further investigated. PMID:24171059

    Intraoperative radiotherapy has been employed in human cancer research for over a decade. Since 1979, trials to assess the acute and late toxicity of IORT have been carried out at the National Cancer Institute in an adult dog model in an attempt to establish dose tolerance guidelines for a variety of organs. Of the 170 animals entered on 12 studies with a minimum follow-up of 2 years, 148 dogs received IORT; 22 control animals received only surgery. Animals were sacrificed at designated intervals following IORT, usually at 1, 6, 12, 24, and 60 month intervals. 102 of 148 irradiated dogs were sacrificed less than 24 months; 46 dogs were followed greater than or equal to 24 months after IORT. To date, 34 of the 46 animals have been sacrificed; the 12 remaining animals are to be followed to 5 years. These 12 animals have minimum follow-up of 30 months. In the irradiated group followed for greater than or equal to 24 months, 10 tumors have arisen in 9 animals. One animal developed an incidental spontaneous breast carcinoma outside the IORT port, discovered only at scheduled post-mortem exam. The remaining nine tumors arose within IORT ports. Two tumors were benign neural tumors--a neuroma and a neurofibroma. One animal had a collision tumor comprised of grade I chondrosarcoma adjacent to grade III osteosarcoma arising in lumbar vertebrae. Two other grade III osteosarcomas, one grade III fibrosarcoma, and one grade III malignant fibrous histiocytoma arose in retroperitoneal/paravertebral sites. An embryonal rhabdomyosarcoma (sarcoma botryoides) arose within the irradiated urinary bladder of one animal. No sham irradiated controls nor IORT animals sacrificed less than 24 months have developed any spontaneous or radiation-induced tumors. The time range of diagnoses of tumors was 24-58 months. The IORT dose range associated with tumor development was 20-35 Gy

    This study was performed in Radiation and Isotopes Center of Khartoum (RICK) and National Cancer Institute (NCI) University of Gazeria. It focused on cancer patients who were treated by radiation therapy in the period between 2008 and 2009. The study investigator the risk and causative factors and geographical distribution over the sudan states and the relationship of incidence with some patient's customs and dietary habits. This study summarizes recent scientific evidence of environmental and occupational links to nearly 30 types of cancer. the discussion of each cancer type is introduced by highlights of trends in incidence. The study considers additional indication that involuntary exposures are linked to cancers, such as patterns observed in different geographic areas and among different population patterns of cancer in children. The purpose of this study is to review scientific evidence, particular y epidemiologic evidence. regarding the contribution of environmental and occupational exposures to the overall cancer incidence in the Sudan. The study discussed that the widespread exposures from air and water pollution, the work environment, exposure resulting form personal habits such as smoking and drinking and the diet are major contributors to cancer in human. In the past three decades, there have been several efforts to estimate the proportion of caner due to these involuntary exposure, starting with an ambitious effort by different scientists. This study provided and alternative interpretation of the evidence of cancer incidence to particular factors. We conclude the study by recommending the significance of giving environmental and occupational links to cancer serious consideration by individuals and institutions concerned with cancer prevention, particularly those involved in research and education.

    This study was planned to evaluate the efficacy and safety of preoperative capecitabine and oxaliplatin (XELOX) without radiation in patients with locally advanced lower rectal cancer. Patients with clinical stage II/III lower rectal cancer underwent three cycles of XELOX followed by radical surgery. The primary end-point was the R0 resection rate. Thirty-one patients were recruited between February 2012 and August 2014. The completion rate of neoadjuvant chemotherapy was 96.5% among the 29 patients who received it; the remaining two refused chemotherapy and underwent immediate surgery. Grade 3-4 adverse events occurred in nine patients (31%). All 29 patients who received chemotherapy underwent radical resection. The R0 resection rate was 96.5% among these 29 patients. Pathological complete responses were achieved in three patients (10.3%) and downstaging occurred in 13 (44.8%). This pilot study found that neoadjuvant XELOX for locally advanced lower rectal cancer is feasible and safe. This neoadjuvant treatment improved resection margin status.

    Breast cancer is a major health problem in Egypt. Her-2/Neu gene is routinely assessed for all breast cancer patients primarily by immunohistochemistry. At National Cancer Institute (NCI), Cairo University, Flourescence In Situ hybridization (FISH) analysis of Her-2/Neu gene is carried out for Her-2/Neu score 2 and for some cases of score 3 (particularly those assessed outside NCI). The test is performed essentially on the primary tumor. However, some situations require testing on corresponding lymph node metastases. There is a debate about the concordance between Her-2/Neu status in the primary tumor and synchronous lymph node metastases in various studies. The aim of this study was to test for the concordance between Her-2/Neu status in the primary breast tumor and corresponding axillary nodal metastases. This is a retrospective study in which FISH analysis of Her-2/Neu was carried out simultaneously on archived material of 50 cases previously diagnosed as invasive duct carcinoma and the corresponding nodal metastases from the Pathology Department, NCI. There was complete concordance between Her-2 status in the primary tumor and the corresponding axillary lymph node metastatic deposits in which Her-2 was amplified in 44% of the studied cohort of Egyptian patients. Her-2/Neu gene assessed by FISH analysis on synchronous lymph node metastases is strongly correlated with the primary tumor. Hence, it is justified to carry out the Her-2/Neu test on synchronous lymph nodes to decide on whether to carry out anti-Her-2/Neu target therapy. Further studies on other metastatic sites is recommended.

    Obesity is a chronic and multifactor disease characterized by presence of excess body fat harmful for health. Several studies have been conducted to assess the possible risk character of different factors for colorectal cancer including the following modifying factors: a diet rich in saturated fats, a diet low in vegetables, physical inactivity, alcohol consumption and obesity. A case-control study was conducted to include 276 adult patients (93 cases and 184 controls) consecutively seen from May, 2008 to May, 2009 in the Institute of Gastroenterology determining a possible association between obesity as risk factor and colorectal cancer. Variables measures included: sex, age, skin color, body mass index, hip-waist circumference and endoscopic location of cancer. We conclude that the colorectal cancer with predominance in female sex and in white people in both groups. Obesity according to a great relation hip-waist had an strong relation with colorectal cancer, which had predominance towards distal colon in both sexes

    The efficacy of endoscopic screening for esophageal cancer in patients with hypopharyngeal cancer remains controversial and its impact on prognosis has not been adequately discussed. We studied the use of endoscopic screening to detect esophageal cancer in hypopharyngeal cancer patients by analyzing the incidence, stage and prognosis. We included 64 patients with hypopharyngeal cancer who received radical radiotherapy at our institute. Chromoendoscopic esophageal examinations with Lugol dye solution were routinely performed at and after treatment for hypopharyngeal cancer. Twenty-eight esophageal cancers were detected in 28 (41%) patients (18 synchronous and 10 metachronous cancers). Of the 28 cancers, 23 were stage 0 or I cancer and 15 of these were treated with endoscopic resection. Local control was achieved in all of these 23 stage 0 or I cancers. The 5-year overall survival rates with esophageal cancer were 83% in stage 0, 47% in stage I and 0% in stage IIA-IVB. This study showed a strikingly high incidence of esophageal cancer in hypopharyngeal cancer patients. We suppose that the combination of early detection by chromoendoscopic examination and endoscopic resection for associated esophageal cancer in hypopharyngeal cancer patients improve prognosis and maintain quality of life.

    National Cancer Institutes (NCI) designated cancer centers use one of three organizational structures. The hypothesis of this study is that there are differences in the amount of annual NCI funding per faculty member based on a cancer center's organizational structure. The study also considers the impact of secondary factors (i.e., the existence of a clinical program, the region and the size of the city in which the cancer center is located) on funding and the number of Howard Hughes Medical Institute (HHMI) investigators at each cancer center. Of the 63 cancer centers, 44 use a matrix structure, 16 have a freestanding structure, and three have a Department of Oncology structure. Kruskal-Wallis tests reveal no statistically significant differences in the amount of funding per faculty member or the number of HHMI investigators between centers with a matrix, freestanding or Department of Oncology structure. Online research and telephone interviews with each cancer center were used to gather information, including: organizational structure, the presence of a clinical program, the number of faculty members, and the number of Howard Hughes Medical Institute investigators. Statistical tests were used to assess the impact which organizational structure has on the amount of funding per faculty member and number of HHMI investigators. While the results seem to suggest that the organizational structure of a given cancer center does not impact the amount of NCI funding or number of HHMI investigators which it attracts, the existence of this relationship is likely masked by the small sample size in this study. Further studies may be appropriate to examine the effect organizational structure has on other measurements which are relevant to cancer centers, such as quality and quantity of research produced.

    We conducted a retrospective study to assess the follow-up of patients with localized breast cancer and the first indicators of advanced breast cancer recurrence. All patients with advanced breast cancer recurrence treated between January 2010 and June 2016 in our institution were registered. Among these patients, 303 patients initially treated for early breast cancer with curative intent were identified. After initial curative treatment, follow-up involved the oncologist, the general practitioner and the gynecologist in 68.0%, 48.9% and 19.1% of cases, respectively. The median DFI was 4 years for luminal A, 3.8 years for luminal B, 3.7 years for HER2-positive and 1.5 years for TNBC (p = 0.07). Breast cancer tumor marker was prescribed for 164 patients (54.1%). No difference in terms of follow-up was observed according to the molecular subtype. Symptoms were the primary indicator of relapse for 143 patients (47.2%). Breast cancer recurrence was discovered by CA 15.3 elevation in 57 patients (18.8%) and by CAE elevation in 3 patients (1%). The rate of relapse diagnosed by elevation of CA 15.3 or CAE was not statistically associated with the molecular subtype (p = 0.65). Luminal A cases showed a significantly higher rate of bone metastases (p = 0.0003). TNBC cases showed a significantly higher rate of local recurrence (p = 0.002) and a borderline statistical significant higher rate of lung/pleural metastases (p = 0.07). Follow-up recommendations could be adapted in clinical practice according to the molecular subtype. General practitioners should be more involved by the specialists in breast cancer follow-up.

    Sentinel lymph node (SLN) examination is a standard in breast cancer patients, with several methods employed along its 20 years history, the last one represented by one-step nucleic acid amplification (OSNA). The latter is a intra-operative molecular assay searching for CK19 mRNA as a surrogate of metastatic cells. Our 3 years experience with OSNA (1122 patients) showed results overlapping those recorded in the same institution with a morphological evaluation (930 patients) of SLN. In detail,...

Materials and methods: From 2010 to 2013, 245,707 breast cancer patients and 8901 patients diagnosed with initial bone metastasis were identified by Surveillance, Epidemiology, and End Results database of the National Cancer Institute. Multivariate logistic and Cox regression were used to identify predictive factors for the presence of bone metastasis and prognosis factors. Kaplan–Meier method and log-rank test were used for survival analysis. Results: Eight thousand nine hundred one patients with initial MBC had bone involvement, accounting for 3.6% of the entire cohort and 62.5% of the patients with initial MBC. Also, 70.5% of patients with bone metastasis were hormone receptor (HR positive (HR+/human epidermal growth factor receptor 2 [HER2]−: 57.6%; HR+/HER2+: 12.9%. Patients with initial bone metastasis had a better 5-year survival rate compared to those with initial brain, liver, or lung metastasis. HR+/HER2− and HR+/HER2+ breast cancer had a propensity of bone metastasis in the entire cohort and were correlated with better prognosis in patients with initial bone metastasis. Local surgery had significantly improved overall survival in initial MBC patients with bone metastasis. Conclusion: Our study has provided population-based estimates of epidemiologic characteristics and prognosis in patients with bone metastasis at the time of

    Full text: Radioiodine therapy is an essential component of thyroid cancer management and these patients require life long follow up at timed interval. Though radioiodine therapy is a well established adjuvant treatment for well differentiated thyroid cancer, still the acceptance by the surgical colleagues and patients is not uniform. In addition, this facility is not available in the eastern part of the country. Therefore, such patients are required to travel more than 1500 K.M. to avail this treatment and subsequent follow up at our Institution. The existing telemedicine facility between SGPGIMS, Lucknow and SCB Medical College, Cuttack provided the opportunity to utilise the system for tele-consultation and tele follow up of thyroid cancer patients. The rationale of this ongoing study is to evaluate the suitability of telemedicine for tele consultation prior to radioiodine therapy and tele follow up following radioiodine therapy of patients with well differentiated thyroid cancer. Thirty patients (10 new cases and 20 follow up cases) were included in this study. New cases were studied on the basis of case history inputs by the operating surgeon and direct patient consultation to find out their suitability for high dose radioiodine therapy. At the same time pre-therapy instructions as well as details of admission were finalised. Follow up of patients (20 in number) were discussed and examined on live along with operating surgeon with respect to compliance of thyroxine suppression therapy, local recurrence and need for further high dose radioiodine therapy. Each time, at least one surgeon and nuclear physician were involved during live evaluation of patients which was done with VSAT, broad band of 256 Kbps band width provided by ISRO, Bangalore, India and case history, radiological and nuclear medicine images were already transmitted prior to live evaluation. All ten new cases were found to be suitable for high dose radioiodine therapy. The appointment dates for

    Until recently, no studies have prospectively evaluated bowel function after sphincter-preserving surgery for rectal cancer with the use of a validated bowel function scoring system. The aim of this study was to investigate possible risk factors for altered bowel function after sphincter-preserving surgery. This was a prospective study. The study was conducted between January 2006 and May 2012 at the authors' institution. Patients who underwent sphincter-preserving rectal cancer surgery were recruited. Bowel function was assessed 1 day before (baseline) and at 1 year after sphincter-preserving surgery or temporary ileostomy takedown with the use of the Memorial Sloan Kettering Cancer Center questionnaire. Multivariable analysis was performed to identify the factors associated with altered bowel function after surgery. Overall, 266 patients were eligible for the analysis. The tumor was located in the upper, middle, and lower rectum in 68 (25.5%), 113 (42.5%), and 85 (32.0%) patients. Intersphincteric resection and temporary ileostomy were performed in 18 (6.8%) and 129 (48.5%) patients. The mean Memorial Sloan Kettering Cancer Center score was 64.5 ± 7.6 at 1 year after sphincter-preserving surgery or temporary ileostomy takedown. The Memorial Sloan Kettering Cancer Center score decreased in 163/266 patients (61.3%) between baseline and 1 year after surgery. Tumor location (p = 0.01), operative method (p = 0.03), anastomotic type (p = 0.01), and temporary ileostomy (p = 0.01) were associated with altered bowel function after sphincter-preserving surgery in univariate analyses. In multivariable analysis, only tumor location was independently associated with impaired bowel function after sphincter-preserving rectal cancer surgery. This study was limited by its nonrandomized design and the lack of measurement before preoperative chemoradiotherapy. We suggest that preoperative counseling should be implemented to inform patients of the risk of bowel dysfunction

  19. Evolution of accesses to information on breast cancer and screening on the Brazilian National Cancer Institute website: an exploratory study

    Paulo Roberto Vasconcellos-Silva

    Full Text Available Abstract Delays in diagnosis due to low Breast Cancer awareness are widespread in Brazil maybe owing to ineffective strategies to raise attention on early diagnosis. As a proxy of collective interest in BC screanning (BCS we studied the monthly accesses to BC and BCS webpages in INCA's website along 48 months. A log analyzer built a time serie (2006-2009 of BC and BCS monthly means, which oscilations were studied by analysis of variance (ANOVA. We found significant increasing accesses to BC and transient “attention peaks”. Enlargement in BC/BCS differences along all period were caused by increasing accesses to BC and decreasing/minor/stable oscillations to SBC pages. These results are consistent with previous reports on increasing interest to BC contrasting with indifference on BCS. In the context of an exploratory study, we discussed some aspects: weakness of a “prevention culture”; lack of confidence in health system and screening programs; “celebrity effect” in the context of media framing; collective perception of risks heightened by perception of social vulnerability. Findings suggest that culture-tailored communication strategies would be necessary to inform Brazilian people about BCS. Future research is needed to study social perceptions and constructions on BC topics.

    Background Prior studies have documented decreased pregnancy rates and early menopause in female cancer survivors; however, infertility rates and reproductive interventions have not been studied. This study investigates infertility and time to pregnancy among female childhood cancer survivors, and analyzes treatment characteristics associated with infertility and subsequent pregnancy. Methods The Childhood Cancer Survivor Study (CCSS) is a cohort study including five-year cancer survivors from 26 institutions who were infertility, medical treatment for infertility, the time to first pregnancy in survivors and siblings, and the risk of infertility in survivors by demographic, disease, and treatment variables were analyzed. Findings Survivors had an increased risk of clinical infertility (>1 year of attempts at conception without success) compared to siblings which was most pronounced at early reproductive ages (≤24 years Relative Risk (RR)=2·92, 95% Confidence Interval (CI) 1·18–7·20; 25–29 years RR=1·61, 95% CI 1·05–2·48; 30–39 years RR=1·37, 95% CI 1·11–1·69). Despite being equally likely to seek treatment for infertility, survivors were less likely to be prescribed medication for treatment of infertility (RR=0·57, 95% CI 0·46–0·70). Increasing doses of uterine radiation and alkylating agent chemotherapy were most strongly associated with infertility. Although survivors had an increased time to pregnancy interval (p=0·032), 64·2% (292/455) with infertility achieved a pregnancy. Interpretation A more comprehensive understanding of infertility after cancer is critical for counseling and decision-making regarding future attempts at conception as well as fertility preservation.

    Change efforts in healthcare sometimes have an ambitious, whole-system remit and seek to achieve fundamental changes in norms and organisational culture rather than (or as well as) restructuring the service. Long-term evaluation of such initiatives is rarely undertaken. We report a secondary analysis of data from an evaluation of a profound institutional change effort in London, England, using a mixed-method longitudinal case study design. The service had received £15 million modernisation funding in 2004, covering multiple organisations and sectors and overseen by a bespoke management and governance infrastructure that was dismantled in 2008. In 2010-11, we gathered data (activity statistics, documents, interviews, questionnaires, site visits) and compared these with data from 2003 to 2008. Data analysis was informed by neo-institutional theory, which considers organisational change as resulting from the material-resource environment and three 'institutional pillars' (regulative, normative and cultural-cognitive), enacted and reproduced via the identities, values and activities of human actors. Explaining the long-term fortunes of the different components of the original programme and their continuing adaptation to a changing context required attention to all three of Scott's pillars and to the interplay between macro institutional structures and embedded human agency. The paper illustrates how neo-institutional theory (which is typically used by academics to theorise macro-level changes in institutional structures over time) can also be applied at a more meso level to inform an empirical analysis of how healthcare organisations achieve change and what helps or hinders efforts to sustain those changes.

    Full Text Available BACKGROUND Stomach cancer is the fourth most common malignancy in the world. 1 Except in countries where screening for stomach cancer is prevalent, most of the distal stomach tumours are diagnosed at advanced stage. Gastric outlet obstruction is usually believed to be a sign of locally-advanced disease. Complete surgical removal of the disease (R0 is the only potentially curative treatment for resectable gastric cancer. The aim of the study is to finda The operability rate of gastric cancer in our institution and the incidence of Gastric Outlet Obstruction (GOO in patients undergoing gastrectomy for distal gastric cancer. b To compare the postoperative outcome in patients with gastric outlet obstruction and those without gastric outlet obstruction. c To see if the histology of the tumour has any role in the development of GOO. MATERIALS AND METHODS This is a retrospective study. The study includes patients who were admitted with carcinoma stomach and underwent operative or nonoperative treatment in our institution during 2013 to 2015. RESULTS Overall operability rate was 45.8%. Operable patients in the GOO group were 47%. Operability in the no outlet obstruction group were 45%. Data shows a slightly increased predilection for GOO in diffuse and mixed type of tumours (statistically not significant. Intestinal tumours had significant rate of anaemia compared to diffuse tumours (p <0.005. Overall mortality was 6.7%. Mortality is higher in the GOO group (8.8%. CONCLUSION (a. Operability rate of distal gastric cancer in our institution is 45.8%. (b. Incidence of gastric outlet obstruction in patients undergoing gastrectomy is 38.2%. (c.

    Purpose: To determine the effectiveness and rate of complications of intensity-modulated radiotherapy (IMRT) in the treatment of cervical lymph node metastases from unknown primary cancer. Methods and Materials: Between February 2005 and November 2008, 25 patients with an unknown primary cancer underwent IMRT, with a median radiation dose of 70 Gy. The bilateral neck and ipsilateral putative pharyngeal mucosa were included in the target volume. All patients had squamous cell carcinoma, except for 1 patient who had adenosquamous differentiation. They were all treated with curative intent. Of the 25 included patients, 20 were men and 5 were women, with a median age of 54 years. Of these patients, 3 had Stage III, 18 had Stage IVa, and 4 had Stage IVb. Of the 25 patients, 18 (72%) received platinum-based chemotherapy in a combined-modality setting. Neck dissection was reserved for residual disease after definitive IMRT. Overall survival, disease-free survival, and locoregional control were calculated using the Kaplan-Meier method. Results: With a median follow-up of 38 months, the overall survival, disease-free survival, and locoregional control rates were all 100% at 3 years. No occurrence of primary cancer was observed during the follow-up period. The reported rates of xerostomia reduced with the interval from the completion of treatment. Nine patients (36%) reported Grade 2 or greater xerostomia at 6 months, and only 2 (8%) of them reported the same grade of salivary function toxicity after 24 months of follow-up. Conclusion: In our institution, IMRT for unknown primary cancer has provided good overall and disease-free survival in all the patients with an acceptable rate of complications. IMRT allowed us to address the bilateral neck and ipsilateral putative pharyngeal mucosa with minimal late salivary function toxicity. The use of concurrent chemotherapy and IMRT for more advanced disease led to good clinical results with reasonable toxicities.

    Adherence to cancer prevention recommendations has been associated with lower incidence of breast cancer in previous studies, but evidence in African American women is limited. This project evaluated the association between adherence to the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) cancer prevention recommendations and breast cancer incidence among African American women. The Black Women's Health Study (analytic cohort = 49,103) is an ongoing prospective cohort study of African American women, ages 21-69 years at baseline (1995). Adherence scores for seven WCRF/AICR recommendations (adherent = 1, partial adherence = 0.5, non-adherence = 0) were calculated using questionnaire data and summed for overall (maximum = 7) and diet only (maximum = 5) scores. Associations between baseline and time-varying adherence scores and breast cancer incidence (N = 1,827 incident cases through 2011) were evaluated using proportional hazards regression. In this cohort, 8.5% adhered >4 recommendations. Adherence at baseline was not associated with breast cancer incidence. Higher overall time-varying adherence (per 0.5 point increase) was associated with lower breast cancer incidence (HR: 0.90, 95% CI: 0.84-0.96). Adherence to physical activity, sugar beverage and red and processed meat recommendations were also associated with reduced risk. Adherence to the WCRF/AICR recommendations was low and may be associated with lower breast cancer incidence in African American women. © 2016 UICC.

    As one migrates from an area of low to high incidence of breast cancer their personal risk of developing breast cancer increases. This is however not equally distributed across all races and ethnicities. This paper specifically examines Filipino migrants. A literature review was conducted to summarize breast cancer incidence, screening practices and trends in treatment amongst Filipino migrants. In addition, a retrospective cohort study was conducted specifically examining the age in which Filipino women were diagnosed with breast cancer compared to Asian and Caucasian counterparts. Filipino women are diagnosed with breast cancer at a statistically significant younger age (53.2) compared to their Asian (55.1) and Caucasian (58.4) counterparts. In addition, they are at an increased risk of developing more aggressive breast cancer with noteworthy disparities in the care they are receiving. The evidence suggest this group is worthy of special focus when diagnosing and treating breast cancer.

    Purpose In daily clinical practice, the indication for adjuvant chemotherapy (CT) is relatively easy to make in patients with early hormone-receptor-positive (HR+) breast cancer with either very poor or very good clinicopathological prognostic variables. However, this decision is much more difficult in patients with intermediate clinicopathological prognostic variables. Here, we evaluate the value of a gene-expression profile identified by the Prosigna gene signature assay in guiding treatment decision-making in patients with these intermediate features. Methods A consecutive cohort of 577 HR + breast cancer patients surgically treated in a single institution between January 2012 and December 2012 was evaluated. From this population, pre- and post-menopausal patients with intermediate prognosis clinicopathological variables were identified and indication of adjuvant CT in these patients was recorded. The gene signature assay was performed retrospectively in this intermediate risk group. Descriptive statistics are presented. Results Among 96 intermediate-risk patients, 64 postmenopausal patients underwent gene signature testing. Subtype distribution was as follows: Luminal A (N = 33; 51.6%), Luminal B (N = 31; 48.4%). Risk of recurrence (ROR) distribution was as follows: ROR-low (n = 16; 25%); ROR-intermediate (N = 26; 40.6%); and ROR-high (N = 22; 34.4%). CT was subsequently administered in 18.7%, 53.8% and 59.0% of the ROR-low, ROR-intermediate and ROR-high groups, respectively. With the use of the gene signature assay, 59.4% of the intermediate cases were re-classified to either ROR-low or ROR-high risk categories. In the ROR-intermediate group, 11/26 patients (42.3%) had Luminal A and 15/26 (57.7%) had Luminal B. Due to follow-up time constraints, no patient outcome results were evaluated. Conclusion The gene signature assay provides clinically useful information and improved treatment decision-making in patients with intermediate risk based on

    2018-03-01

    The evidence on a cancer-protective effect of the Mediterranean diet (MD) is still limited. Therefore, we investigated the association between MD adherence and lung cancer risk. Data were used from 120 852 participants of the Netherlands Cohort Study (NLCS), aged 55-69 years. Dietary habits were assessed at baseline (1986) using a validated FFQ and alternate and modified Mediterranean diet scores (aMED and mMED, respectively), including and excluding alcohol, were calculated. After 20·3 years of follow-up, 2861 lung cancer cases and 3720 subcohort members (case-cohort design) could be included in multivariable Cox regression analyses. High (6-8) v. low (0-3) aMED excluding alcohol was associated with non-significantly reduced lung cancer risks in men and women with hazard ratios of 0·91 (95 % CI 0·72, 1·15) and 0·73 (95 % CI 0·49, 1·09), respectively. aMED-containing models generally fitted better than mMED-containing models. In never smokers, a borderline significant decreasing trend in lung cancer risk was observed with increasing aMED excluding alcohol. Analyses stratified by the histological lung cancer subtypes did not identify subtypes with a particularly strong inverse relation with MD adherence. Generally, the performance of aMED and World Cancer Research Fund/American Institute for Cancer Research dietary score variants without alcohol was comparable. In conclusion, MD adherence was non-significantly inversely associated with lung cancer risk in the NLCS. Future studies should focus on differences in associations across the sexes and histological subtypes. Furthermore, exclusion of alcohol from MD scores should be investigated more extensively, primarily with respect to a potential role of the MD in cancer prevention.

    Full Text Available Cancer treatment options in sub-Saharan Africa are scarce despite an increasing burden of disease. Identification of those cancer patients who would benefit most from the limited resources available would allow broader and more effective therapy.We conducted a retrospective analysis of patients over the age of 18 at the time of a pathologic diagnosis of NHL between 2003 and 2010 who were residents of Kyandondo County (Uganda and presented to the Uganda Cancer Institute for care.A total of 128 patients were included in this analysis. Chemotherapy was recommended to 117 (91.4% of the patients; the odds of recommending chemotherapy decreased for each additional month of reported symptoms prior to diagnosis. Of the 117 patients to whom chemotherapy was recommended, 111 (86.7% patients received at least 1 cycle of chemotherapy; HIV infected patients, as well as those with a lower hemoglobin and advanced disease at the time of diagnosis were significantly less likely to complete therapy. Among the patients who initiated chemotherapy, twenty patients died prior to treatment completion (including nine who died within 30 days. Hemoglobin level at the time of presentation was the only variable associated with early mortality in the adjusted model.In resource-poor areas, it is essential to align health care expenditures with interventions likely to provide benefit to affected populations. Targeting cancer therapy to those with a favorable chance of responding will not only save limited resources, but will also prevent harm in those patients unlikely to realize an effect of cancer-directed therapy.

    Retrospective single-center studies have shown that diffusion-weighted magnetic resonance imaging (DWI) is promising for identification of patients with rectal cancer with a complete tumor response after neoadjuvant chemoradiotherapy (CRT), using certain volumetric thresholds. This study aims to validate the diagnostic value of these volume thresholds in a larger, independent, and bi-institutional patient cohort. A total of 112 patients with locally advanced rectal cancer (2 centers) treated with a long course of CRT were enrolled. Patients underwent standard T2W-magnetic resonance imaging and DWI, both pre- and post-CRT. Two experienced readers independently determined pre-CRT and post-CRT tumor volumes (cm) on T2W-magnetic resonance image and diffusion-weighted magnetic resonance image by means of freehand tumor delineation. Tumor volume reduction rates (Δvolume) were calculated. Previously determined T2W and DWI threshold values for prevolume, postvolume, and Δvolume were tested to "prospectively" assess their respective diagnostic value in discriminating patients with a complete tumor response from patients with residual tumor. Twenty patients had a complete response. Using the average measurements between the 2 readers, areas under the curve for the pre-/post-/Δvolumes was 0.73/0.82/0.78 for T2W-magnetic resonance imaging and 0.77/0.92/0.86 for DWI, respectively. For T2W-volumetry, sensitivity and specificity using the predefined volume thresholds were 55% and 74% for pre-, 60% and 89% for post-, and 60% and 86% for Δvolume. For DWI volumetry, sensitivity and specificity were 65% and 76% for pre-, 70% and 98% for post-, and 70% and 93% for Δvolume. Previously established DWI volume thresholds can be reproduced with good results. Post-CRT DWI volumetry offers the best results for the detection of patients with a complete response after CRT with an area under the curve of 0.92, sensitivity of 70%, and specificity of 98%.

    The utility of cancer databases for oropharyngeal cancer studies is limited by lack of information on human papillomavirus (HPV) status. The purpose of this study was to develop a surrogate that can be used to adjust for the effect of HPV status on survival. The study cohort included 6419 patients diagnosed with oropharyngeal squamous cell carcinoma between 2004 and 2012, identified in the National Cancer Database (NCDB). The HPV surrogate score was developed using a logistic regression model predicting HPV-positive status. The HPV surrogate score was predictive of HPV status (area under the curve [AUC] 0.73; accuracy of 70.4%). Similar to HPV-positive tumors, HPV surrogate positive tumors were associated with improved overall survival (OS; hazard ratio [HR] 0.73; 95% confidence interval [CI] 0.59-0.91; P = .005), after adjusting for important covariates. The HPV surrogate score is useful for adjusting for the effect of HPV status on survival in studies utilizing cancer databases. © 2017 Wiley Periodicals, Inc.

    2015-07-01

    Full Text Available Background: Caregivers of individuals suffering from cancer illnesses are at risk of having subjected to mental health consequences. There is a paucity of data comparing the caregiver burden of cancer breast and cancer cervix patients. Aim: The aim of the present study is to compare the caregiver burden of cancer breast and cancer cervix patients. To study the association of caregiver burden with demographic factors like age, gender, duration of caregiving etc. Materials & Methods: This Cross sectional study is performed on the key relatives of patients of 31 cancer cervix and 31 cancer breast patients. Burden assessment schedule was used. Results: Our findings suggest burden is more in male caregivers of breast cancer patients. It is not so in caregivers of cancer cervix patients. Whenever the caregiver is closely related to the patients the burden is high in both groups. Whenever the burden scores were high the depression scores were also high. Treatment modalities as a whole correlates with burden scores in caregivers of breast cancer patients but not in cancer cervix patients. Conclusion: Caregivers with breast and cervical cancer patients are vulnerable if the caregiver is male, from low socioeconomical background, more closely related and when the patients received poor treatment modalities.

Methods and Materials: A total of 112 patients with clinical Stage III NSCLC (American Joint Commission on Cancer 1997) enrolled in four Radiation Therapy Oncology Group studies (83-11, 84-03, 84-07, and 88-08 nonchemotherapy arms) at a single institution were analyzed retrospectively for overall survival (OS) and comorbidity. Of the 112 patients, 105 (94%) completed their assigned radiotherapy. The median assigned dose was 50.4 Gy to the lymphatics (range 45-50.4 Gy) and 70.2 Gy to the primary tumor (range 60-79.2 Gy). Comorbidity was rated retrospectively using the Cumulative Illness Rating Scale for Geriatrics (CIRS-G) and Charlson scales. Karnofsky performance scores (KPSs) and weight loss were prospectively recorded. Because only 8 patients had a KPS of 70). Results: The median survival was 10.39 months (range 7.87-12.91). The 2-, 3-, and 5-year OS rate was 20.5%, 12.5%, and 7.1%, respectively. On univariate analysis, clinical stage (IIIA vs. IIIB) was found to be a statistically significant factor influencing OS (p=0.026), and the histologic features, grade, tumor size as measured on CT scans, age, tobacco use, weight loss ≥5%, and total dose delivered to the primary tumor were not. A KPS of ≤70 (p=0.001), the presence of a CIRS-G score of 4 (extremely severe; p=0.0002), and a severity index of >2 (p 2 were independently associated with inferior OS; clinical tumor stage was not found to be an independent prognostic factor. Conclusion: KPS and comorbidity are important independent prognostic factors in Stage III NSCLC. Comorbidity should be included in protocols studying advanced stage NSCLC and used for stratification

The term “institutional stakeholder” includes persons in leading positions with responsibility in hospitals’ multidrug-resistant bacterial organism management. They have great influence on how strategies on multidrug-resistant bacterial organism management approaches in institutions of the public health system are designed. This study targeted institutional stakeholders’ individual perspectives on multidrug-resistant bacterial organism colonization or infection and isolation measures at the end of life. Methods: Between March and December 2014, institutional stakeholders of two study centers, a German palliative care unit and a geriatric ward, were queried in semistructured interviews. Interviews were audiotaped, transcribed verbatim, and analyzed qualitatively with the aid of the software MAXQDA for qualitative data analysis using principles of Grounded Theory.

    Canadian financial institutions have been in rapid change in the past five years. In response to these changes, the Department of Finance issued a discussion paper: The Regulation of Canadian Financial Institutions, in April 1985, and the government intends to introduce legislation in the fall. This paper studi.es the combinantion of financial institutions from the viewpoint of ruin probability. In risk theory developed to describe insurance companies [1,2,3,4,5J, the ruin probability of a company with initial reserve (capital) u is 6 1 -:;-7;;f3 u 1jJ(u) = H6 e H6 (1) Here,we assume that claims arrive as a Poisson process, and the claim amount is distributed as exponential distribution with expectation liS. 6 is the loading, i.e., premium charged is (1+6) times expected claims. Financial institutions are treated as "insurance companies": the difference between interest charged and interest paid is regarded as premiums, loan defaults are treated as claims.

    After primary surgery, patients diagnosed with early stage breast cancer undergo radiological investigations based on pathologic stage of disease to rule out distant metastases. Published guidelines can aid clinicians in determining which tests are appropriate based on stage of disease. We wished to assess the consistency of radiological staging in an academic community oncology setting with standard guidelines and to determine the overall impact of non-adherence to these guidelines. A retrospective cohort study was conducted for new breast cancer patients seen at a single institution between January 2009 and April 2010. Patients were included if initial diagnosis and primary surgery was at this institution. Pathologic stage and radiological tests completed were recorded. A literature review was performed and the results were compared with those from this study to determine overall adherence rates. Subsequently, a cost analysis was performed to determine the financial impact at this centre. 231 patients met eligibility criteria for inclusion in this study. A large proportion of patients were over-staged with 129 patients (55%) undergoing unnecessary investigations according to guidelines. Specifically, 59% of stage I patients and 58% of stage II patients were over-investigated. Distant metastases at the time of diagnosis were found in three patients, all of whom had stage III disease (1.3%). The literature reviewed revealed similar non-adherence rates in other centres. The estimated cost of such non-adherence is in the range of $78 (CDN) per new early stage breast cancer patient seen at this centre. This oncology centre has a low adherence to practice guidelines for staging investigations in breast cancer patients, with 55% of patients undergoing unnecessary tests. Very few patients had metastases at diagnosis, and all had pathological stage III disease. Efforts may need to focus on improving knowledge translation across clinical oncology settings to increase

    Background: Studies of related individuals have consistently demonstrated notable familial aggregation of cancer. We aim to estimate the heritability and genetic correlation attributable to the additive effects of common single-nucleotide polymorphisms (SNPs) for cancer at 13 anatomical sites. Methods: Between 2007 and 2014, the US National Cancer Institute has generated data from genome-wide association studies (GWAS) for 49 492 cancer case patients and 34 131 control patients. We apply novel mixed model methodology (GCTA) to this GWAS data to estimate the heritability of individual cancers, as well as the proportion of heritability attributable to cigarette smoking in smoking-related cancers, and the genetic correlation between pairs of cancers. Results: GWAS heritability was statistically significant at nearly all sites, with the estimates of array-based heritability, hl 2, on the liability threshold (LT) scale ranging from 0.05 to 0.38. Estimating the combined heritability of multiple smoking characteristics, we calculate that at least 24% (95% confidence interval [CI] = 14% to 37%) and 7% (95% CI = 4% to 11%) of the heritability for lung and bladder cancer, respectively, can be attributed to genetic determinants of smoking. Most pairs of cancers studied did not show evidence of strong genetic correlation. We found only four pairs of cancers with marginally statistically significant correlations, specifically kidney and testes (ρ = 0.73, SE = 0.28), diffuse large B-cell lymphoma (DLBCL) and pediatric osteosarcoma (ρ = 0.53, SE = 0.21), DLBCL and chronic lymphocytic leukemia (CLL) (ρ = 0.51, SE =0.18), and bladder and lung (ρ = 0.35, SE = 0.14). Correlation analysis also indicates that the genetic architecture of lung cancer differs between a smoking population of European ancestry and a nonsmoking Asian population, allowing for the possibility that the genetic etiology for the same disease can vary by population and environmental exposures. Conclusion: Our

    Dentistry is considered to be a stressful profession due to different factors caused by work, representing a threat to dentists'health. The objectives of this work were to identify and compare chronic stress in dentists among the different health institutions and the association of stress with risk factors. The study in question is observational, transversal and comparative; 256 dentists were included, distributed among five public health institutions in the city of Guadalajara, Jalisco, Mexico, namely: the Mexican Institute of Social Security (IMSS), the Ministry of Health (SS), the Integral Development of the Family (DIF), the Social Security Services Institute for the Workers (ISSSTE) and the University of Guadalajara (U. de G) Data were obtained by means of the census technique. Stress was identified using the Stress Symptoms Inventory and the statistical analysis was performed using the Odds Ratio (O.R.) and the chi-square statistic. From the total population studied, 219 subjects presented high levels of chronic stress and 37, low levels. In the results of comparative analysis, significant differences were found between IMSS and U. de G and likewise between IMSS and SS. However, in the analysis of association, only U. de G was found to be associated with the high level of chronic stress.

    Skin cancers are the most common types of cancer and their incidence has shown an increase of ∼4 to 8% per year over the last 40 years. The majority of skin cancers (∼97%) are non-melanoma skin cancers, mainly represented by basal cell (80%) and squamous cell carcinomas (20%). The use of intra-operative frozen section remains controversial in the surgical treatment of non-melanoma skin cancer, being commonly considered an optional tool, the reliability and effectiveness of which remain questionable. A large retrospective study was conducted to examine 670 surgical excisions of non-melanoma skin cancers of the head and neck in 481 patients over a period of nine years, between May, 2002 and December, 2011, at the Plastic and Reconstructive Surgery Unit of the University of Pavia, Salvatore Maugeri Research and Care Institute, Pavia, Italy. Results demonstrated the paradoxical ineffectiveness of an intra-operative frozen section biopsy in pursuing higher rates of radical excision in non-melanoma skin cancers. Nevertheless, a more detailed analysis on the use of frozen sections focusing on the various anatomical sites of the body demonstrated a reverse trend in the eyelids and canthi, where a higher success rate (87.50 vs. 69.77%) in the surgical treatment of non-melanoma skin cancers was obtained with the use of an intra-operative frozen section biopsy. Results of the present study suggested that intra-operative frozen section biopsy be routinely used in the surgical treatment of nonmelanoma skin tumors involving the eyelids and canthi.

    Purpose: To quantify the impact of differing magnitudes of simulated linear accelerator errors on the dose to the target volume and organs at risk for nasopharynx VMAT. Methods: Ten nasopharynx cancer patients were retrospectively replanned twice with one full arc VMAT by two institutions. Treatment uncertainties (gantry angle and collimator in degrees, MLC field size and MLC shifts in mm) were introduced into these plans at increments of 5,2,1,−1,−2 and −5. This was completed using an in-house Python script within Pinnacle3 and analysed using 3DVH and MatLab. The mean and maximum dose were calculated for the Planning Target Volume (PTV1), parotids, brainstem, and spinal cord and then compared to the original baseline plan. The D1cc was also calculated for the spinal cord and brainstem. Patient average results were compared across institutions. Results: Introduced gantry angle errors had the smallest effect of dose, no tolerances were exceeded for one institution, and the second institutions VMAT plans were only exceeded for gantry angle of ±5° affecting different sided parotids by 14–18%. PTV1, brainstem and spinal cord tolerances were exceeded for collimator angles of ±5 degrees, MLC shifts and MLC field sizes of ±1 and beyond, at the first institution. At the second institution, sensitivity to errors was marginally higher for some errors including the collimator error producing doses exceeding tolerances above ±2 degrees, and marginally lower with tolerances exceeded above MLC shifts of ±2. The largest differences occur with MLC field sizes, with both institutions reporting exceeded tolerances, for all introduced errors (±1 and beyond). Conclusion: The plan robustness for VMAT nasopharynx plans has been demonstrated. Gantry errors have the least impact on patient doses, however MLC field sizes exceed tolerances even with relatively low introduced errors and also produce the largest errors. This was consistent across both departments. The authors

    Research with high throughput technologies has propitiated the segmentation of different types of tumors into very small subgroups characterized by the presence of very rare molecular alterations. The identification of these subgroups and the apparition of new agents targeting these infrequent alterations are already affecting the way in which clinical trials are being conducted with an increased need to identify those patients harboring specific molecular alterations. In this review we describe some of the currently ongoing and future studies at the Institut Gustave Roussy that aim for the identification of potential therapeutic targets for cancer patients with the incorporation of high throughput technologies into daily practice including aCGH, next generation sequencing and the creation of a software that allows for target identification specific for each tumor. The initial intention is to enrich clinical trials with cancer patients carrying certain molecular alterations in order to increase the possibility of demonstrating benefit from a targeted agent. Mid and long term aims are to facilitate and speed up the process of drug development as well as to implement the concept of personalized medicine.

    Observational studies indicate that higher volumes of physical activity are associated with improved disease outcomes among colon cancer survivors. The aim of this report is to describe the purpose, study design, methods, and recruitment results of the courage trial, a National Cancer Institute (NCI) sponsored, phase II, randomized, dose-response exercise trial among colon cancer survivors. The primary objective of the courage trial is to quantify the feasibility, safety, and physiologic effects of low-dose (150 min·week(-1)) and high-dose (300 min·week(-1)) moderate-intensity aerobic exercise compared to usual-care control group over six months. The exercise groups are provided with in-home treadmills and heart rate monitors. Between January and July 2015, 1433 letters were mailed using a population-based state cancer registry; 126 colon cancer survivors inquired about participation, and 39 were randomized onto the study protocol. Age was associated with inquiry about study participation (Pclinical, or geographic characteristics were associated with study inquiry or randomization. The final trial participant was randomized in August 2015. Six month endpoint data collection was completed in February 2016. The recruitment of colon cancer survivors into an exercise trial is feasible. The findings from this trial will inform key design aspects for future phase 2 and phase 3 randomized controlled trials to examine the efficacy of exercise to improve clinical outcomes among colon cancer survivors.

    Background: Uterine cancer is still a prevalent disease in Chile. Is common to treat patients with tumors in stages IIB and IIIB where the risk of pelvic and paraortic limph node involvement is very high. Its treatment is radio-chemotherapy. Objective: To present a retrospective analysis of patients that suffered cervix-uterine cancer who were treated with radiotherapy including the aortic-lumbar area. Methods: From the revision of patients who were treated of cervix-uterine cancer between the years 1995 and 2007, 39 were treated including aortic-lumbar chains. Evolution and toxicity were analyzed. Two radiotherapy techniques were used. The first one, during the nineties, included two parallel previous and later and opposed fields, and a second technique, currently used, where pelvis and paraortic are radiated at the same time through four lateral (AP-PA) fields. Results: The dosimeter analysis of both techniques shows that there is a higher volume of radiated normal tissue with the two fields techniques, mainly in the small bowel. On the other hand, the toxicity was significantly different being today's technique less toxic and showing low gastrointestinal

    Although studies of metastasectomy have been limited primarily to institutional experiences, reports of favorable long-term outcomes have generated increasing interest. In the current study, the authors attempted to define the national practice patterns in metastasectomy for 4 common malignancies with varying responsiveness to systemic therapy. The National (Nationwide) Inpatient Sample was used to estimate the national incidence of metastasectomy for colorectal cancer, lung cancer, breast cancer, and melanoma from 2000 through 2011. Incidence-adjusted rates were determined for liver, lung, brain, small bowel, and adrenal metastasectomies. The average annual percentage change (AAPC) in metastasectomy by cancer type was calculated using joinpoint regression. Colorectal cancer was the most common indication for metastasectomy (87,407 cases; 95% confidence interval [95% CI], 86,307-88,507 cases) followed by lung cancer (58,245 cases; 95% CI, 57,453-59,036 cases), breast cancer (26,271 cases; 95% CI, 25,672-26,870 cases), and melanoma (20,298 cases; 95% CI, 19,897-20,699 cases). Metastasectomy increased significantly for all cancer types over the study period: colorectal cancer (AAPC, 6.83; 95% CI, 5.7-7.9), lung cancer (AAPC, 5.8; 95% CI, 5.1-6.4), breast cancer (AAPC, 5.5; 95% CI, 3.7-7.3), and melanoma (AAPC, 4.03; 95% CI, 2.1-6.0). Despite an increasing number of comorbidities in patients undergoing metastasectomy (P<.05 for each cancer type), inpatient mortality rates after metastasectomy fell for all cancer types, most significantly for colorectal (AAPC, -5.49; 95% CI, -8.2 to -2.7) and lung (AAPC, -6.2; 95% CI, -11.7 to -0.3) cancers. The increasing performance of metastasectomy was largely driven by high-volume institutions, in which patients had a lower mean number of comorbidities (P<.01 for all cancer types) and lower inpatient mortality (P<.01 for all cancers except melanoma). From 2000 through 2011, the performance of metastasectomy increased substantially

    Dietary pattern analysis considers combinations of food intake and may offer a better measure to assess diet-cancer associations than examining individual foods or nutrients. Although tobacco exposure is the major risk factor for lung cancer, few studies have examined whether dietary patterns, based on preexisting dietary guidelines, influence lung cancer risk. After controlling for smoking, we examined associations between four diet quality indices-Healthy Eating Index-2010 (HEI-2010), Alternate Healthy Eating Index-2010 (AHEI-2010), alternate Mediterranean Diet score (aMED) and Dietary Approaches to Stop Hypertension (DASH)-and lung cancer risk in the NIH-AARP (National Institutes of Health-American Association of Retired Persons) Diet and Health study. Baseline dietary intake was assessed in 460 770 participants. Over a median of 10.5 years of follow-up, 9272 incident lung cancer cases occurred. Cox proportional hazards regression was used to estimate hazard ratios (HRs) and confidence intervals (CIs). Comparing highest to lowest quintiles, HRs (95% CIs) for lung cancer were as follows: HEI-2010=0.83 (0.77-0.89), AHEI-2010=0.86 (0.80-0.92), aMED=0.85 (0.79-0.91) and DASH=0.84 (0.78-0.90). Among the individual components of the dietary indices, higher consumption of whole grains and fruits was significantly inversely associated with lung cancer risk for several of the diet indices. Total index score analyses stratified by smoking status showed inverse associations with lung cancer for former smokers; however, only HEI-2010 was inversely associated in current smokers and no index score was inversely associated among never smokers. Although smoking is the factor most strongly associated with lung cancer, this study adds to a growing body of evidence that diet may have a modest role in reducing lung cancer risk, especially among former smokers.

    2007-01-01

    Purpose: Radiotherapy differed widely in east and south-east Asia because of technical, cultural, and socio-economic differences. With the purpose of standardizing radiotherapy for cervical cancer in the region, an international clinical study was conducted. Materials and methods: Eleven institutions in eight Asian countries participated in the study. Between 1996 and 1998, 210 patients with stage IIIB cervical cancer were enrolled. Patients were treated with a combination of external beam radiotherapy (total dose, 50 Gy) and either high-dose-rate (HDR) or low-dose-rate (LDR) intracavitary brachytherapy (ICBT) according to the institutional practice. The planned point A dose was 20-28 Gy/4 fractions for HDR-ICBT and 30-40 Gy/1-2 fractions for LDR-ICBT. Results: Hundred patients were treated with HDR-ICBT and 110 were treated with LDR-ICBT. The ICBT doses actually delivered to point A ranged widely: 12-32 Gy in the HDR group and 26-52.7 Gy in the LDR group. The 5-year follow-up rate among the countries differed greatly, from 29% to 100%. The 5-year major complication rates were 6% in the HDR group and 10% in the LDR group. The 5-year overall survival rates were 51.1% in the HDR group and 57.5% in the LDR group. Conclusions: Although there were several problems with treatment compliance and patients' follow-up, the study suggests that the protocols provided favorable outcomes with acceptable rates of late complications in the treatment of advanced cervical cancer in east and south-east Asia

    During the past several decades, an increasing incidence of thyroid cancer has been observed worldwide. Nitrate inhibits iodide uptake by the thyroid, potentially disrupting thyroid function. An increased risk of thyroid cancer associated with nitrate intake was recently reported in a cohort study of older women in Iowa. We evaluated dietary nitrate and nitrite intake and thyroid cancer risk overall and for subtypes in the National Institutes of Health-American Association of Retired Persons (NIH-AARP) Diet and Health Study, a large prospective cohort of 490,194 men and women, ages 50-71 years in 1995-1996. Dietary intakes were assessed using a 124-item food frequency questionnaire. During an average of 7 years of follow-up we identified 370 incident thyroid cancer cases (170 men, 200 women) with complete dietary information. Among men, increasing nitrate intake was positively associated with thyroid cancer risk (relative risk [RR] for the highest quintile versus lowest quintile RR = 2.28, 95% confidence interval [CI]: 1.29-4.041; p-trend cancer for either men or women. We evaluated risk for the two main types of thyroid cancer. We found positive associations for nitrate intake and both papillary (RR = 2.10; 95% CI: 1.09-4.05; p-trend = 0.05) and follicular thyroid cancer (RR = 3.42; 95% CI: 1.03-11.4; p-trend = 0.01) among men. Nitrite intake was associated with increased risk of follicular thyroid cancer (RR = 2.74; 95%CI: 0.86-8.77; p-trend = 0.04) among men. Our results support a role of nitrate in thyroid cancer risk and suggest that further studies to investigate these exposures are warranted. Published 2010 UICC.

    Background: Associations of coffee consumption with cancer mortality are inconsistent for many types of cancer, and confounding by smoking is an important concern. Methods: Cox proportional hazards regression was used to estimate multivariable-adjusted HRs for coffee consumption associated with death from all cancers combined and from specific cancer types among 922,896 Cancer Prevention Study-II participants ages 28-94 years who completed a four-page questionnaire and were cancer free at baseline in 1982. Results: During follow-up through 2012, there were 118,738 cancer-related deaths. There was a nonlinear association between coffee consumption and all-cancer death among current smokers and former smokers and no association among never smokers. Among nonsmokers, a 2 cup/day increase in coffee consumption was inversely associated with death from colorectal [HR = 0.97; 95% confidence interval (CI) 0.95-0.99], liver [HR = 0.92; 95% CI, 0.88-0.96], and female breast (HR = 0.97; 95% CI, 0.94-0.99) cancers, and positively associated with esophageal cancer-related death (HR = 1.07; 95% CI, 1.02-1.12). For head and neck cancer, a nonlinear inverse association was observed starting at 2-3 cups per day (HR = 0.72; 95% CI, 0.55-0.95), with similar associations observed at higher levels of consumption. Conclusions: These findings are consistent with many other studies that suggest coffee drinking is associated with a lower risk of colorectal, liver, female breast, and head and neck cancer. The association of coffee consumption with higher risk of esophageal cancer among nonsmokers in our study should be confirmed. Impact: These results underscore the importance of assessing associations between coffee consumption and cancer mortality by smoking status.

    Full Text Available Abstract Background The impact of skin invasion in node negative breast cancer is uncertain. Methods We determined the prognosis in 97 node negative breast cancer patients (case group who had tumors with skin invasion. Then we compared these patients with 4500 node negative invasive breast cancer patients treated surgically in the same period. Results Patients with skin invasion tended to be older, had more invasive lobular carcinoma and larger tumor size, and were less likely to have breast conserving surgery than those in the control group. The 5-year disease-free survival rate in the case group was 94.0%. There was no significant difference in the 10-year disease-specific overall survival rates in terms of skin invasion in node negative patients (90.7% in the case group, 92.9% in the control group; p = 0.2032. Conclusion Results suggest that skin invasion has no impact on survival in node negative invasive breast cancer patients. The adjuvant regimens which the individual institute applies for node negative breast cancer should be used regardless of skin invasion.

    Childhood cancer survivors (CCS) treated with cranial radiation therapy (CRT) are at risk of developing meningiomas. The aim of this study was to evaluate the cumulative incidence of meningiomas in a cohort of CCS who previously underwent CRT. We considered all CCS who received CRT and were followed up at the "Transition Unit for Childhood Cancer Survivors" in Turin. Even though asymptomatic, they had at least one brain computed tomography or magnetic resonance imaging performed at a minimum interval of 10 years after treatment for pediatric cancer. We identified 90 patients (median follow-up 24.6 years). Fifteen patients developed meningioma (median time from pediatric cancer, 22.5 years). In four patients, it was suspected on the basis of neurological symptoms (i.e., headache or seizures), whereas all other cases, including five giant meningiomas, were discovered in otherwise asymptomatic patients. Multiple meningiomas were discovered in four CCS. Ten patients underwent surgical resection. An atypical meningioma (grade II WHO) was reported in four patients. One patient with multiple meningiomas died for a rapid growth of the intracranial lesions. A second neoplasm (SN) other than meningioma was diagnosed in five out of the 15 patients with meningioma and in ten out of the 75 CCS without meningioma. Cox multivariate analysis showed that the occurrence of meningioma was associated with the development of other SNs, whereas age, sex, or CRT dose had no influence. CCS at risk of the development of meningioma deserve close clinical follow-up, especially those affected by other SNs.

    Full Text Available Schools, the where educational activities are carried out, are among the major institutions society considers as important. Schools undertake strategic responsibilities in maintaining cultural values and conveying them to future generations. The primary responsibility in achieving these missions is assigned to the school administrators. The purpose of this study is to determine the perceptions of school administrators on institutional culture. This is a qualitative study conducted on school administrators who were selected based on the volunteering principle. Perceptions of school administrators concerning their institutions’ culture and the differences between their institutional culture and other institution’s cultures were determined and analyzed. Findings of this study suggest that school administrators have both positive and negative opinions regarding their institutional culture and cultural difference. While love-respect, collaboration-solidarity and common history were prominent positive opinions; lack of communication, lack of shared values and low expectation were prominent negative opinions. In addition, participants stated the environment as a crucial factor when defining culture.

    Oral cancer is a common malignancy in Nepal and many other South East Asian countries, which is predisposed by a variety of potentially malignant oral diseases. Considering the importance of knowledge of health professionals and their role in early diagnosis and reduction of cancer statistics, this study aims to evaluate the awareness of undergraduate dental and medical students towards oral cancer. The study involved undergraduate dental and medical students of BP Koirala Institute of Health Sciences, Nepal. A self-administered questionnaire adapted from Carter to Ogden was distributed. One hundred forty-three dental and 311 medical students responded to the questionnaire. Significantly more dental (80.4 %) than medical students (36.0 %) were found to routinely examine the oral mucosa. Tobacco smoking and chewing were the most commonly recognized risk factors by both medical and dental students. Most of the students found ulcer as the common change associated with oral cancer. Only 30 out of the total students felt very well informed about oral cancer. This study has demonstrated a lack of awareness in some aspects of oral cancer among medical and dental students which highlights the need to frame new teaching methodologies. Similar studies from other health institutions would provide an insight regarding the same and could be a base for formulating a uniform curriculum in the implementation of knowledge regarding oral cancer.

    Research purpose: The objectives of this study were to establish an understanding of ‘transformational leadership’ and to determine the extent to which it was employed by leaders in an institution of higher education which had incorporated another institution. Motivations for the study: The study provides a starting point, not only for the successful implementation of higher education changes in the future but also the building of leadership commitment and alignment to the proposed changes in the sector as well as the development of institutional leadership teams to take responsibility for any other transformation processes. Research design, approach and method: The population of the study consisted of 350 full-time employees of the institution who had experienced the incorporation process. Two samples – one consisting of six executive management leaders and the other consisting of 153 employees – were used. Both qualitative and quantitative research approaches were employed using the case study method. Main findings: Results showed that transformational principles of idealised influence, intellectual stimulation, and inspirational motivation principles were used more than others and that employees were generally not satisfied with how the incorporation process had taken place. Practical/managerial implications: The results of the study affected the attitude and satisfaction of the employees in this study. Contribution/value-add: The study reveals that leaders in the institution played key roles such as shared vision, team work and the creation of an enabling environment. An important point that has emanated from this study is the evidence that during transformation, a lack of strategic direction and empowering of followers and capacitating them leads to dissatisfaction with the whole process, despite the transformation process being declared a success.

    Full Text Available Colorectal cancers stands 3rd in males and 2nd in females in order of frequency of most common cancers worldwide and in developed countries. And is 4th common in males and 5th common in females in developing countries. Colonic tumors located at the caecum, ascending colon, hepatic flexure, transverse colon, and splenic flexure were defined as right sided colon cancer and tumors located at the descending colon, sigmoid, rectosigmoid and rectum were defined as left sided colorectal cancer. The difference in percentage deviation is statistically not significant and present study concludes that there is no actual migration of colon cancers towards right side. In the present study there is higher proportion of males being affected with Right colon cancers group which is significant and doesn’t go in accordance with the literature published, where females are more affected. Since this is institutional based study there is further need for studies based on population. As the mean age at presentation was very earlier than in the developed countries, the thrust is in us to have an effective screening programs.

    Ovarian cancer is a leading cause of cancer death among women in the United States and it has the highest mortality rate of all gynecologic cancers. Internationally, there is a five-fold variation in incidence and mortality of ovarian cancer, which suggests a role for environmental factors, including diet. Nitrate and nitrite are found in various food items and they are precursors of N-nitroso compounds, which are known carcinogens in animal models. We evaluated dietary nitrate and nitrite intake and epithelial ovarian cancer in the National Institutes of Health (NIH)-AARP Diet and Health Study, including 151 316 women aged 50-71 years at the time of the baseline questionnaire in 1995-1996. The nitrate and nitrite intake was assessed using a 124-item validated food frequency questionnaire. Through 31 December 2006, 709 incident epithelial ovarian cancer cases with complete dietary information were identified. Using Cox proportional hazards regression to estimate hazard ratios and 95% confidence intervals (CIs), women in the highest intake quintile of dietary nitrate had a 31% increased risk (95% CI: 1.01-1.68) of epithelial ovarian cancer, compared with those in the lowest intake quintile. Although there was no association for total dietary nitrite, those in the highest intake category of animal sources of nitrite had a 34% increased risk (95% CI: 1.05-1.69) of ovarian cancer. There were no clear differences in risk by histologic subtype of ovarian cancer. Our findings suggest that a role of dietary nitrate and nitrite in ovarian cancer risk should be followed in other large cohort studies.

    Case-control studies have reported inconsistent results concerning breast cancer risk and polymorphisms in genes that control endogenous estrogen biosynthesis. We report findings from the first family-based association study examining associations between female breast cancer risk and polymorphisms in two key estrogen-biosynthesis genes CYP17 (T→C promoter polymorphism) and CYP19 (TTTA repeat polymorphism). We conducted the study among 278 nuclear families containing one or more daughters with breast cancer, with a total of 1123 family members (702 with available constitutional DNA and questionnaire data and 421 without them). These nuclear families were selected from breast cancer families participating in the Metropolitan New York Registry, one of the six centers of the National Cancer Institute's Breast Cancer Family Registry. We used likelihood-based statistical methods to examine allelic associations. We found the CYP19 allele with 11 TTTA repeats to be associated with breast cancer risk in these families. We also found that maternal (but not paternal) carrier status of CYP19 alleles with 11 repeats tended to be associated with breast cancer risk in daughters (independently of the daughters' own genotype), suggesting a possible in utero effect of CYP19. We found no association of a woman's breast cancer risk either with her own or with her mother's CYP17 genotype. This family-based study indicates that a woman's personal and maternal carrier status of CYP19 11 TTTA repeat allele might be related to increased breast cancer risk. However, because this is the first study to report an association between CYP19 11 TTTA repeat allele and breast cancer, and because multiple comparisons have been made, the associations should be interpreted with caution and need confirmation in future family-based studies

    Background: Prostate cancer is thought to be the most heritable cancer, although little is known about how this genetic contribution varies across age. Methods: To address this question, we undertook the world’s largest prospective study in the Nordic Twin Study of Cancer cohort, including 18...... risk and liability. Results: The cumulative risk of prostate cancer was similar to that of the background population. The cumulative risk for twins whose co-twin was diagnosed with prostate cancer was greater for MZ than for DZ twins across all ages. Among concordantly affected pairs, the time between...... diagnoses was significantly shorter for MZ than DZ pairs (median 3.8 versus 6.5 years, respectively). Genetic differences contributed substantially to variation in both the risk and the liability (heritability=58% (95% CI 52%–63%) of developing prostate cancer. The relative contribution of genetic factors...

    2008-01-01

    Purpose: The aim of this study was to elucidate the characteristic magnetic resonance (MR) appearance of breast cancers, as well as, its variations and to investigate the pathology providing different patterns of dynamic-MR appearances. Materials and methods: Fifty-two women with cancer underwent mastectomy (52 tumors resected) and had MR imaging at our institution between April 2001 and March 2004. MR images of T1WI, T2WI, dynamic-MRI and contrast-enhanced T1WI were obtained and evaluated. Dynamic-MR images were correlated with pathological findings. Results: Common MR appearance of breast cancer was a focal mass either with irregular or spiculated margins with similar signal intensity on T1WI as and similar to higher signal intensity on T2WI compared to the normal mammary gland. On static contrast-enhanced T1WI, apparent enhancement was typically observed. On dynamic MRI, tumor-rim-enhancement on an early phase image and washout enhancement pattern on dynamic images, both characteristic for breast cancer, were observed, however, the prevalence of them was relatively low, which could be explained by the variation of histopathology among breast cancer nodules. Conclusion: In diagnosing breast masses on MRI, as well as the common and characteristic findings of breast cancer, the variations of MR findings and their underlying histopathology should also be considered

    Advances have been made in treatment and outcomes for pediatric cancer. However adolescents and young adults (AYAs) with cancer have not experienced similar relative improvements. We undertook a study to develop the methodology necessary for epidemiologic cancer research in these age groups. Our goal was to create the Kids, Adolescents, and Young Adults Cancer (KAYAC) project to create a resource to address research questions relevant to this population. We used a combination of clinic and population-based ascertainment to enroll 111 cases aged 0-39 for this methodology development study. The largest groups of cancer types enrolled include: breast cancer, leukemia, lymphoma, and melanoma. The overall participation rate is 69.8% and varies by age and tumor type. The study included patients, mothers, and fathers. The methods used to establish this resource are described, and the values of the resource in studies of childhood and young adult cancer are outlined.

    An increase in the incidence of thyroid cancer in children has been reported since 1990 in areas of Belarus, Russia and Ukraine which have been highly contaminated during the Chernobyl accident in 1986. A similar increase is now observed in young adults in the same areas. In France, thyroid cancer is characterized by low occurrence and good prognosis. However, the incidence of thyroid cancer has been increasing for more than 20 years, and in 1986, the Chernobyl cloud of radioactive dust crossed the French territory. Thus, the National institute for public health surveillance (I.n.V.S.) carried out several studies to evaluate whether the incidence increase in thyroid cancer is related to radiation exposure from the Chernobyl accident. Since 2000, the I.n.V.S. is in charge of a national multidisciplinary approach involving a wide range of public health actors, including the French network of cancer registries (Francim). Since 2003, the I.n.V.S. has been working on improving the surveillance system according to the actions described in the national cancer plan 2003-2007. The I.n.V.S. has increased its financial contribution to cancer registries including the national registry of solid tumors in children, which was created in 2000. The Institute is also working on the implementation of a multi source system for the national cancer surveillance in link with cancer registries. For the twentieth anniversary of the Chernobyl accident, the I.n.V.S. is publishing updated results from the latest research conducted in close collaboration with the partners. These results do not support the initial hypothesis of a potential 'Chernobyl effect' in France. The increase in the incidence of thyroid cancer is also reported in most of developed countries. Practices in cancer diagnosis and the increased rate of total thyroidectomy for benign lesion may lead pathologists to unexpectedly discover small thyroid tumors. This fact is likely to explain most of the incidence increase

    The National Cancer Institute (INCA) Quality Program in Radiotherapy (PQRT) started in 1999 as a 3 years pilot program with only 33 participant institutions. Due to its positive results, it has been integrated to the permanent INCA programs and its activities extended to all the radiotherapy services where patients from the National Health System (SUS) are treated. They are about 150 services (90% of all the available Brazilian radiotherapy services). The PQRT activities objective is to allow that radiotherapeutic treatments can be carried out just like planned, according to international quality and safety standards. The PQRT main activities are: on-site quality control audits, postal TLD audits in reference and non-reference conditions, training and development of research projects. The on-site quality control audits have already evaluated 75 teletherapy units (37 Co-60 and 38 linear accelerators), performing dosimetric, electrical, mechanical and safety tests. The Postal TLD audits used, till 2002, for the 33 participants, the International Atomic Energy Agency (IAEA) system for reference conditions. Five audits have been performed with this simple system. Since 2003, the PQRT postal TLD audit program is using its own system, developed for reference and non-reference conditions. This new system has been already applied to 58 beams (18 Co-60 and 40 linacs). In total, in reference conditions, PQRT has performed 400 audits in reference conditions (190 Co-60 and 210 linacs). Eighteen courses attended to the participants, covering their main practical problems. In parallel, some research studies have been carried out.

    Full Text Available Purpose : Adaptive magnetic resonance imaging (MRI-based brachytherapy results in improved local control and decreased high-grade toxicities compared to historical controls. Incorporating MRI into the workflow of a department can be a major challenge when initiating an MRI-based brachytherapy program. This project aims to describe the goals, challenges, and solutions when initiating an MRI-based cervical cancer brachytherapy program at our institution. Material and methods : We describe the 6-month multi-disciplinary planning phase to initiate an MRI-based brachytherapy program. We describe the specific challenges that were encountered prior to treating our first patient. Results : We describe the solutions that were realized and executed to solve the challenges that we faced to establish our MRI-based brachytherapy program. We emphasize detailed coordination of care, planning, and communication to make the workflow feasible. We detail the imaging and radiation physics solutions to safely deliver MRI-based brachytherapy. The focus of these efforts is always on the delivery of optimal, state of the art patient care and treatment delivery within the context of our available institutional resources. Conclusions : Previous publications have supported a transition to MRI-based brachytherapy, and this can be safely and efficiently accomplished as described in this manuscript.

    Purpose: To test the hypotheses that (1) the increased risk of stroke conferred by childhood cranial radiation therapy (CRT) persists into adulthood; and (2) atherosclerotic risk factors further increase the stroke risk in cancer survivors. Methods and Materials: The Childhood Cancer Survivor Study is a multi-institutional retrospective cohort study of 14,358 5-year survivors of childhood cancer and 4023 randomly selected sibling controls with longitudinal follow-up. Age-adjusted incidence rates of self-reported late-occurring (≥5 years after diagnosis) first stroke were calculated. Multivariable Cox proportional hazards models were used to identify independent stroke predictors. Results: During a mean follow-up of 23.3 years, 292 survivors reported a late-occurring stroke. The age-adjusted stroke rate per 100,000 person-years was 77 (95% confidence interval [CI] 62-96), compared with 9.3 (95% CI 4-23) for siblings. Treatment with CRT increased stroke risk in a dose-dependent manner: hazard ratio 5.9 (95% CI 3.5-9.9) for 30-49 Gy CRT and 11.0 (7.4-17.0) for 50+ Gy CRT. The cumulative stroke incidence in survivors treated with 50+ Gy CRT was 1.1% (95% CI 0.4-1.8%) at 10 years after diagnosis and 12% (95% CI 8.9-15.0%) at 30 years. Hypertension increased stroke hazard by 4-fold (95% CI 2.8-5.5) and in black survivors by 16-fold (95% CI 6.9-36.6). Conclusion: Young adult pediatric cancer survivors have an increased stroke risk that is associated with CRT in a dose-dependent manner. Atherosclerotic risk factors enhanced this risk and should be treated aggressively.

    Full Text Available Purpose: Lung cancer is the most common cause of cancer mortality in the world. There are limited studies on survival outcomes of lung cancer in developing countries such as India. This study analyzed the outcomes of patients with lung cancer who underwent treatment at Cancer Institute (WIA, Chennai, India, between 2006 and 2015 to determine survival outcomes and identify prognostic factors. Patients and Methods: In all, 678 patients with lung cancer underwent treatment. Median age was 58 years, and 91% of patients had non–small-cell lung cancer (NSCLC. Testing for epidermal growth factor receptor mutation was performed in 132 of 347 patients and 61 (46% were positive. Results: Median progression-free survival was 6.9 months and overall survival (OS was 7.6 months for patients with NSCLC. Median progression-free survival was 6 months and OS was 7.2 months for patients with small-cell lung cancer. On multivariable analysis, the factors found to be significantly associated with inferior OS in NSCLC included nonadenocarcinoma histology, performance status more than 2, and stage. In small-cell lung cancer, younger age and earlier stage at presentation showed significantly better survival. Conclusion: Our study highlights the challenges faced in treating lung cancer in India. Although median survival in advanced-stage lung cancer is still poor, strategies such as personalized medicine and use of second-line and maintenance chemotherapy may significantly improve the survival in patients with advanced-stage lung cancer in developing countries.

    2013-01-01

    Background Communication about prognosis and treatment choices is essential for informed decision making in advanced cancer. This article describes an investigation designed to facilitate communication and decision making among oncologists, patients with advanced cancer, and their caregivers. Methods/design The Values and Options in Cancer Care (VOICE) Study is a National Cancer Institute sponsored randomized controlled trial conducted in the Rochester/Buffalo, NY and Sacramento, CA regions. A total of 40 oncologists, approximately 400 patients with advanced cancer, and their family/friend caregivers (one per patient, when available) are expected to enroll in the study. Drawing upon ecological theory, the intervention uses a two-pronged approach: oncologists complete a multifaceted tailored educational intervention involving standardized patient instructors (SPIs), and patients and caregivers complete a coaching intervention to facilitate prioritizing and discussing questions and concerns. Follow-up data will be collected approximately quarterly for up to three years. Discussion The intervention is hypothesized to enhance patient-centered communication, quality of care, and patient outcomes. Analyses will examine the effects of the intervention on key elements of physician-patient-caregiver communication (primary outcomes), the physician-patient relationship, shared understanding of prognosis, patient well-being, and health service utilization (secondary outcomes).

  18. Curcumin AntiCancer Studies in Pancreatic Cancer

    2016-07-01

    Full Text Available Pancreatic cancer (PC is one of the deadliest cancers worldwide. Surgical resection remains the only curative therapeutic treatment for this disease, although only the minority of patients can be resected due to late diagnosis. Systemic gemcitabine-based chemotherapy plus nab-paclitaxel are used as the gold-standard therapy for patients with advanced PC; although this treatment is associated with a better overall survival compared to the old treatment, many side effects and poor results are still present. Therefore, new alternative therapies have been considered for treatment of advanced PC. Several preclinical studies have demonstrated that curcumin, a naturally occurring polyphenolic compound, has anticancer effects against different types of cancer, including PC, by modulating many molecular targets. Regarding PC, in vitro studies have shown potent cytotoxic effects of curcumin on different PC cell lines including MiaPaCa-2, Panc-1, AsPC-1, and BxPC-3. In addition, in vivo studies on PC models have shown that the anti-proliferative effects of curcumin are caused by the inhibition of oxidative stress and angiogenesis and are due to the induction of apoptosis. On the basis of these results, several researchers tested the anticancer effects of curcumin in clinical trials, trying to overcome the poor bioavailability of this agent by developing new bioavailable forms of curcumin. In this article, we review the results of pre-clinical and clinical studies on the effects of curcumin in the treatment of PC.

    Early diagnosis of HIV associated lymphoma is challenging because the definitive diagnostic procedure of biopsy, requires skills and equipment that are not readily available. As a consequence, diagnosis may be delayed increasing the risk of mortality. We set out to determine the frequency and risk factors associated with the misdiagnosis of HIV associated lymphoma as tuberculosis (TB) among patients attending the Uganda Cancer Institute (UCI). A retrospective cohort study design was used among HIV patients with associated lymphoma patients attending the UCI, Kampala, Uganda between February and March 2015. Eligible patient charts were reviewed for information on TB treatment, socio-demographics, laboratory parameters (Hemoglobin, CD4cells count and lactate dehydrogenase) and clinical presentation using a semi structured data extraction form. A total of 183 charts were reviewed; 106/183 were males (57.9%), the median age was 35 (IQR, 28-45). Fifty six (30.6%) patients had a possible misdiagnosis as TB and their median time on TB treatment was 3.5 (1-5.3) months. In multivariate analysis the presence of chest pain had an odd ratio (OR) of 4.4 (95% CI 1.89-10.58, p HIV associated lymphoma attending UCI are misdiagnosed and treated as TB. Chest pain and stage III and IV of lymphoma were associated with an increased risk of a possible misdiagnosis of lymphoma as TB.

    A report is given of a cancer mortality study in Caithness, Sutherland, Orkney and Shetland between 1958 and 1982. For Caithness and Sutherland, the numbers of male deaths from all kinds of cancer was significantly less than the numbers expected from figures for Scotland as a whole; for females no difference was observed; the parish of Latheron showed an excess of leukaemia cases. For Orkney and Shetland, the total number of cancer deaths for both sexes was significantly less than for Scotland as a whole. In Shetland, there was an excess of lymphatic leukaemia in Northmaven based on four deaths observed. In Orkney, one parish showed an excess of lymphatic and haematopoietic cancers. (UK)

    The long-term oncologic stability of laparoscopic surgery for colon cancer was established, and laparoscopic surgery was accepted as an alternative to conventional open surgery for colon cancer. However, transverse colon cancer was excluded from the majority of the previous prospective studies. As a result, debate on laparoscopic surgery for transverse colon cancer continues. This study aimed to compare the clinicopathologic outcome of laparoscopic surgery with that of conventional open surgery for transverse colon cancer. From August 2004 to December 2007, 106 cases of transverse colon cancer were managed by resection at our institution, and 89 of these cases were included in this study. Age, sex, body mass index (BMI), operation time, blood loss, time to first flatus, time to start of diet, hospital stay, complications, tumor size, distal resection margin, proximal resection margin, and number of nodes harvested were compared between the two groups. No significant differences were found between the laparoscopic and conventional groups in terms of age, sex, BMI, operation time, or hospital stay. The mean blood loss during the operations was significantly less in the laparoscopic group (113.8 +/- 128.9 ml) than in the conventional group (278.8 +/- 268.7 ml; p transverse colon cancer, and the oncologic quality of laparoscopic surgery was found to be acceptable compared with conventional open surgery.

    Protracted preoperative radio-chemotherapy with a 5-FU-based scheme, or a short course of preoperative radiotherapy without chemotherapy, are the standard neo-adjuvant treatments for resectable stage II-III rectal cancer. Local failure rates are low and reproducible, between 6 and 15% when followed with a 'Total Meso-rectal Excision'. Nevertheless, the therapeutic strategy needs to be improved: distant metastatic recurrence rates remain stable around 30 to 35%, while both sphincter and sexual sequels are still significant. The aim of the present paper was to analyse the ongoing trials listed on the following search engines: the Institut National du Cancer in France, the National Cancer Institute and the National Institute of Health in the United States, and the major cooperative groups. Keywords for the search were: 'rectal cancer', 'preoperative radiotherapy', 'phase II-III', 'preoperative chemotherapy', 'adjuvant chemotherapy' and 'surgery'. Twenty-three trials were selected and classified in different groups, each of them addressing a question of strategy: (1) place of adjuvant chemotherapy; (2) optimization of preoperative radiotherapy; (3) evaluation of new radiosensitization protocols and/or neo-adjuvant chemotherapy; (4) optimization of techniques and timing of surgery; (5) place of radiotherapy for non resectable or metastatic tumors.

    Self-efficacy for coping with cancer plays a critical role in influencing psychological cancer-related outcomes, some studies suggested its role in enhancing or reducing the effects of psychological interventions in cancer patients. Reiki has recently been included among the efficacious complementary therapeutic intervention for cancer patients. The present study evaluated the role of self-efficacy for coping with cancer as buffer of the Reiki treatment effects on cancer-related symptoms in a randomized controlled trial (intervention versus control group) of breast cancer patients (N=110) during the pre-surgery phase. Results showed that self-efficacy for coping with cancer can influence the effect of a Reiki treatment. Higher efficacious patients showed a more powerful effect of the Reiki intervention on both anxiety and mood than the low efficacious patients. From a practical perspective, the study provides insightful results for healthcare professionals. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    In Japan, breast-conserving surgery with closed cavity has generally been performed for breast cancer patients, and accelerated partial breast irradiation (APBI) is considered difficult because Asian females generally have smaller breast sizes than Western females. Therefore, common identification of target and treatment plan method in APBI is required. A prospective multicenter study was conducted in Japan to determine institutional compliance with APBI using high-dose-rate interstitial brachytherapy (ISBT) designed for Japanese female patients. For this study, 46 patients were recruited at eight institutions from January 2009 to December 2011. The reproducibility of the ISBT–APBI plan was evaluated using three criteria: (1) minimum clinical target volume dose with a clip dose ≥ 6 Gy/fraction, (2) irradiated volume constraint of 40-150 cm 3 , and (3) uniformity of dose distribution, expressed as the dose non-uniformity ratio (DNR, V150/V100) < 0.35. The ISBT–APBI plan for each patient was considered reproducible when all three criteria were met. When the number of non-reproducible patients was ≤ 4 at study completion, APBI at this institution was considered statistically reproducible. Half of the patients (52 %) had a small bra size (A/B cup). The mean values of the dose-constrained parameters were as follows: Vref, 117 cm 3 (range, 40-282), DNR, 0.30 (range, 0.22-0.51), and clip dose, 784 cGy (range, 469-3146). A total of 43/46 treatment plans were judged to be compliant and ISBT–APBI was concluded to be reproducible. This study showed that multi-institutional ISBT–APBI treatment plan was reproducible for small breast patient with closed cavity

    Purpose: Clinical pathways are an important tool used to manage the quality in health care by standardizing processes. This study evaluated the impact of the implementation of a peer-reviewed clinical pathway in a large, integrated National Cancer Institute-Designated Comprehensive Cancer Center Network. Methods: In 2003, we implemented a clinical pathway for the management of bone metastases with palliative radiation therapy. In 2009, we required the entry of management decisions into an online tool that records pathway choices. The pathway specified 1 or 5 fractions for symptomatic bone metastases with the option of 10-14 fractions for certain clinical situations. The data were obtained from 13 integrated sites (3 central academic, 10 community locations) from 2003 through 2010. Results: In this study, 7905 sites were treated with 64% of courses delivered in community practice and 36% in academic locations. Academic practices were more likely than community practices to treat with 1-5 fractions (63% vs. 23%; p < 0.0001). The number of delivered fractions decreased gradually from 2003 to 2010 for both academic and community practices (p < 0.0001); however, greater numbers of fractions were selected more often in community practices (p < 0.0001). Using multivariate logistic regression, we found that a significantly greater selection of 1-5 fractions developed after implementation online pathway monitoring (2009) with an odds ratio of 1.2 (confidence interval, 1.1-1.4) for community and 1.3 (confidence interval, 1.1-1.6) for academic practices. The mean number of fractions also decreased after online peer review from 6.3 to 6.0 for academic (p = 0.07) and 9.4 to 9.0 for community practices (p < 0.0001). Conclusion: This is one of the first studies to examine the efficacy of a clinical pathway for radiation oncology in an integrated cancer network. Clinical pathway implementation appears to be effective in changing patterns of care, particularly with online clinical

    Anemia is very commonly seen in most of the malignancies including cancer cervix. Anemia has long been reported to adversely affect the efficacy of radiation treatment in cervical cancer. At our center, carcinoma cervix accounts for approximately 8-10% of all malignancies. The objective of this study is to see the impact of anemia in the treatment of cancer cervix. In the present study, we collected data of treatment results of FIGO stage II and III cancer cervix patients retrospectively treated in years of 2009-10. We have tried to assess the outcome of results in patients whom haemoglobin (Hb) level < 10 gm/dl and e''10 gm/dl. Out of 200 patients of disease with baseline Hb less than 10 gm/dl, 80(40%) patients had residual disease after 4 weeks of completion of treatment. Out of 168 patients with baseline Hb more than 10 gm/dl, 42(25%) had residual disease (p-0.0012 i.e highly significant). Our study shows that there is a good disease control at local site in patients with higher pretreatment Hb level. Effect of pretreatment Hb on treatment outcome in terms of overall survival, disease free survival, and local relapse free survival along with effect on corrective measures should be studied in detail.

    Purpose: To assess the accuracy of the commercially available deformable image registration (DIR) software for thoracic images at multiple institutions. Methods and Materials: Thoracic 4-dimensional (4D) CT images of 10 patients with esophageal or lung cancer were used. Datasets for these patients were provided by DIR-lab ( (dir-lab.com)) and included a coordinate list of anatomic landmarks (300 bronchial bifurcations) that had been manually identified. Deformable image registration was performed between the peak-inhale and -exhale images. Deformable image registration error was determined by calculating the difference at each landmark point between the displacement calculated by DIR software and that calculated by the landmark. Results: Eleven institutions participated in this study: 4 used RayStation (RaySearch Laboratories, Stockholm, Sweden), 5 used MIM Software (Cleveland, OH), and 3 used Velocity (Varian Medical Systems, Palo Alto, CA). The ranges of the average absolute registration errors over all cases were as follows: 0.48 to 1.51 mm (right-left), 0.53 to 2.86 mm (anterior-posterior), 0.85 to 4.46 mm (superior-inferior), and 1.26 to 6.20 mm (3-dimensional). For each DIR software package, the average 3-dimensional registration error (range) was as follows: RayStation, 3.28 mm (1.26-3.91 mm); MIM Software, 3.29 mm (2.17-3.61 mm); and Velocity, 5.01 mm (4.02-6.20 mm). These results demonstrate that there was moderate variation among institutions, although the DIR software was the same. Conclusions: We evaluated the commercially available DIR software using thoracic 4D-CT images from multiple centers. Our results demonstrated that DIR accuracy differed among institutions because it was dependent on both the DIR software and procedure. Our results could be helpful for establishing prospective clinical trials and for the widespread use of DIR software. In addition, for clinical care, we should try to find the optimal DIR procedure using thoracic 4D

    The findings of numerous studies have illustrated that there is still a high proportion of cancer patients in Eastern and Middle-East countries including Iran, who are not properly informed of their disease due to the concealment atmosphere which still prevails. This descriptive qualitative study is aimed at exploring perceptions of patients, patients' family members, physicians and nurses regarding cancer disclosure challenges. Thirty-five participants (15 patients, 6 family members, 9 physicians, and 5 nurses) were selected through purposive sampling. The data were collected through in-depth interviews; after which they were analyzed using a qualitative content analysis with an inductive approach. Data analysis revealed the following three categories: first, challenges related to healthcare system which deals with the deficiencies, strains and concerns in medical setting and healthcare team training; second, challenges related to family insistence on concealment which includes their fear of cancer disclosure and its negative impact on the patients; and third, challenges related to policy making which consists of deficiencies in legislative and supportive institutions for advocacy of truth telling. Successful move from concealment to effective disclosure attitude in cancer patients in Iran requires a national determination for resolving challenges in medical education as well as other different social, cultural and policy making dimensions.

    Obesity is a chronic and multifactor disease characterized by presence of excess body fat harmful for health. Several studies have been conducted to assess the possible risk character of different factors for colorectal cancer including the following modifying factors: a diet rich in saturated fats, a diet low in vegetables, physical inactivity, alcohol consumption and obesity. A case-control study was conducted to include 276 adult patients (93 cases and 184 controls) consecutively seen from May, 2008 to May, 2009 in the Institute of Gastroenterology determining a possible association between obesity as risk factor and colorectal cancer. Variables measures included: sex, age, skin color, body mass index, hip-waist circumference and endoscopic location of cancer. We conclude that the colorectal cancer with predominance in female sex and in white people in both groups. Obesity according to a great relation hip-waist had an strong relation with colorectal cancer, which had predominance towards distal colon in both sexes

    The expanding "valley of death" in drug development is leaving potentially life-saving new chemical entities and molecular targets fallow. This situation is forcing early-stage companies to think creatively about moving their technologies forward, especially as institutional investors show more interest in later stages of development. Drug repurposing, a strategy to examine existing drugs for therapeutic value against different diseases, is an emerging method to bring an off-market drug back onto the market. Tau Therapeutics LLC identified the role of T-type calcium channel blockers (Cav3) in cancer proliferation, but the company was unable to attract funding while having both a nonvalidated drug target and new chemical entities. To change the risk profile of the company, Tau set out to repurpose the known Cav3 drug mibefradil as a proof of concept for the treatment of cancer. Mibefradil was launched for hypertension in the 1990s but withdrawn because of drug-drug interactions. A new sequential combination treatment, termed Interlaced Therapy™, uses short-term administration of mibefradil to enhance the overall therapeutic potential of conventional anticancer agents. Mibefradil is currently in a phase Ib clinical trial with the National Cancer Institute (NCI) Adult Brain Tumor Consortium. Mibefradil has been repurposed from an abandoned antihypertensive to a targeted solid tumor treatment, and it has been rescued from drug-drug interactions by using short-term dose exposure. Tau is using the early success of mibefradil as a proof of concept to build a platform technology of Cav3 blockers for broad antitumor applications in combination with new targeted cancer therapies, well-established chemotherapies, and radiation.

    Community district heating, utilizing hot water produced through electrical/thermal cogeneration, is seen as an integral part of Minnesota's Energy Policy and Conservation Plan. Several studies have been conducted which consider the technical and institutional issues affecting implementation of cogenerated district heating in the Minneapolis and St. Paul Metropolitan Area. The state of the technical art of cogenerated hot water district heating is assumed to be transferable from European experience. Institutional questions relating to such factors as the form of ownership, financing, operation, regulation, and product marketability cannot be transferred from the European experience, and have been the subject of an extensive investigation. The form and function of the Institutional Issues Study, and some of the preliminary conclusions and recommendations resulting from the study are discussed.

    Full Text Available Purpose. To analyze the patterns and associations of adjunctive service visits by head and neck cancer patients receiving primary, concurrent chemoradiation therapy. Methods. Retrospective chart review of patients receiving adjunctive support during a uniform chemoradiation regimen for stages III-IV head and neck squamous cell carcinoma. Univariate and multivariate models for each outcome were obtained from simple and multivariate linear regression analyses. Results. Fifty-two consecutive patients were assessed. Female gender, single marital status, and nonprivate insurance were factors associated with an increased number of social work visits. In a multivariate analysis, female gender and marital status were related to increased social work services. Female gender and stage IV disease were significant for increased nursing visits. In a multivariate analysis for nursing visits, living greater than 20 miles between home and hospital was a negative predictive factor. Conclusion. Treatment of advanced stage head and neck cancer with concurrent chemoradiation warrants a multidisciplinary approach. Female gender, single marital status, and stage IV disease were correlated with increased utilization of social work and nursing services. Distance over 20 miles from the center was a negative factor. This information may help guide the treatment team to allocate resources for the comprehensive care of patients.

    Patient satisfaction is an important outcome measure of quality of cancer care and 1 of the 4 core study outcomes of the National Cancer Institute (NCI)-sponsored Patient Navigation Research Program to reduce race/ethnicity-based disparities in cancer care. There is no existing patient satisfaction measure that spans the spectrum of cancer-related care. The objective of this study was to develop a Patient Satisfaction With Cancer Care measure that is relevant to patients receiving diagnostic/therapeutic cancer-related care. The authors developed a conceptual framework, an operational definition of Patient Satisfaction With Cancer Care, and an item pool based on literature review, expert feedback, group discussion, and consensus. The 35-item Patient Satisfaction With Cancer Care measure was administered to 891 participants from the multisite NCI-sponsored Patient Navigation Research Program. Principal components analysis (PCA) was conducted for latent structure analysis. Internal consistency was assessed using Cronbach coefficient alpha (α). Divergent analysis was performed using correlation analyses between the Patient Satisfaction With Cancer Care, the Communication and Attitudinal Self-Efficacy-Cancer, and demographic variables. The PCA revealed a 1-dimensional measure with items forming a coherent set explaining 62% of the variance in patient satisfaction. Reliability assessment revealed high internal consistency (α ranging from 0.95 to 0.96). The Patient Satisfaction With Cancer Care demonstrated good face validity, convergent validity, and divergent validity, as indicated by moderate correlations with subscales of the Communication and Attitudinal Self-Efficacy-Cancer (all P .05). The Patient Satisfaction With Cancer Care is a valid tool for assessing satisfaction with cancer-related care for this sample. Copyright © 2010 American Cancer Society.

These differences appear to have a direct impact on the clinical presentation, histology, and outcomes of lung cancer. Women are more likely to present with lung adenocarcinoma, tend to receive a diagnosis at an earlier age, and are more likely to be diagnosed with localized disease. Women may also be more predisposed to molecular aberrations resulting from the carcinogenic effects of tobacco, but do not appear to be more susceptible than men to developing lung cancer. The gender differences found in female lung cancer make it mandatory that gender stratification is used in clinical trials in order to improve the survival rates of patients with lung cancer.Keywords: lung cancer, adenocarcinoma, women, genetic susceptibility, genetic differences, tobacco

    Bereaved parents experience significant psychosocial and health sequelae, suggesting that this population may benefit from the ongoing extension of support and resources throughout the grief journey. The interaction of hospital staff with patients and families at the end of a child's life and after death profoundly affects parental grief, offering a unique opportunity for the medical community to positively impact the bereavement experience. The current study was conducted to explore the role of the health care team and medical institutions in the grief journeys of parents whose child died a cancer-related death. Eleven bereaved parents participated in 2 focus groups. Responses to each of the 3 main prompts were coded and analyzed independently using semantic content analysis techniques. Four main concepts were identified within the parental narratives, including the importance of strong and ongoing relationships between providers and bereaved families, the importance of high-quality communication, the effect of negative experiences between providers and families on parental grief, and the importance of the institution's role in the grief journeys of bereaved parents. Bereaved parents consistently identified the critical role played by medical staff and medical institutions throughout the grief journey. Key components of bereavement support identified by parents should serve to guide the actions of providers as well as provide a template for the development of a comprehensive bereavement program within an institution.

    Purpose: To identify factors significantly influencing accrual to clinical protocols by analyzing radiation Patterns of Care Study (PCS) surveys of 3,047 randomly selected radiotherapy (RT) patients. Methods and Materials: Patterns of Care Study surveys from disease sites studied for the periods 1992-1994 and 1996-1999 (breast cancer, n = 1,080; prostate cancer, n = 1,149; esophageal cancer, n = 818) were analyzed. The PCS is a National Cancer Institute-funded national survey of randomly selected RT institutions in the United States. Patients with nonmetastatic disease who received RT as definitive or adjuvant therapy were randomly selected from eligible patients at each institution. To determine national estimates, individual patient records were weighted by the relative contribution of each institution and patients within each institution. Data regarding participation in clinical trials were recorded. The factors age, gender, race, type of insurance, and practice type of treating institution (academic or not) were studied by univariate and multivariate analyses. Results: Overall, only 2.7% of all patients were accrued to clinical protocols. Of these, 57% were enrolled on institutional review board-approved institutional trials, and 43% on National Cancer Institute collaborative group studies. On multivariate analysis, patients treated at academic facilities (p = 0.0001) and white patients (vs. African Americans, p = 0.0002) were significantly more likely to participate in clinical oncology trials. Age, gender, type of cancer, and type of insurance were not predictive. Conclusions: Practice type and race significantly influence enrollment onto clinical oncology trials. This suggests that increased communication and education regarding protocols, particularly focusing on physicians in nonacademic settings and minority patients, will be essential to enhance accrual

    The Institute for Fusion Studies is a national center for theoretical fusion plasma physics research. Its purposes are: (1) to conduct research on theoretical questions concerning the achievement of controlled fusion energy by means of magnetic confinement--including both fundamental problems of long-range significance, as well as shorter-term issues; (2) to serve as a center for information exchange, nationally and internationally, by hosting exchange visits, conferences, and workshops; (3) and to train students and postdoctoral research personnel for the fusion energy program and plasma physics research areas. The theoretical research results that are obtained by the Institute contribute mainly to the progress of national and international efforts in nuclear fusion research, whose goal is the development of fusion power.as a basic energy source. In addition to its primary focus on fusion physics, the Institute is also involved with research in related fields, such as advanced computing techniques, nonlinear dynamics, plasma astrophysics, and accelerator physics. The work of EFS scientists continued to receive national and international recognition. Numerous invited papers were given during the past year at workshops, conferences, and scientific meetings. Last year IFS scientists published 95 scientific articles in technical journals and monographs

    Smoking is a well-known risk factor for esophageal cancer. However, there are few reports that directly evaluate smoking as a prognostic factor for esophageal cancer. Moreover, scarce evidence is available on whether smoking interacts with major treatment modalities of esophageal cancer. In this study we retrospectively analyzed 364 patients with esophageal squamous cell cancer who were treated between 2001 and 2005 at our institution. Background characteristics, including smoking history, were analyzed as potential prognostic factors. Of the 363 patients, 76 patients (20.9%) were non-smokers or light smokers (non-heavy), whereas 287 patients (79.1%) were heavy smokers. The 5-year survival rate for non-heavy smokers and heavy smokers was 61.8% (95% confidence interval [CI]: 49.1-72.2) vs 44.6% (95% CI: 38.2-50.9), respectively. In a multivariate Cox model (adjusted for age, gender, performance status, alcohol consumption, histology, tumor length, International Union Against Cancer [UICC] stage, and treatment), the hazard ratio for heavy smokers in comparison with non-heavy smokers was 1.73 (95% CI: 1.12-2.68; P=0.013). When we stratified by treatment method, heavy smoking was significantly associated with poor survival only in patients treated by chemoradiotherapy (hazard ratio, 2.43; 95% CI: 1.38-4.27; P=0.002). More importantly, a statistically significant interaction between heavy smoking history and treatment modality was observed (P=0.041). Our results indicated that smoking history is strongly associated with poor prognosis in patients with esophageal cancer, especially those treated by chemoradiotherapy. Further investigation is warranted to explain this different prognosis. (author)

    JSC researchers study carcinogenesis, cancer prevention and treatment along with epidemiological (primarily retrospective and longitudinal) studies, modeling, and interactions with the environment such as radiation, nutritional, and endocrine changes related to space flight along with behaviors such as smoking. Cancer research is a major focus for human space flight due to the exposure to space radiation which consists of particles of varying charges and energies, and secondary neutrons. The JSC laboratories collaborate with investigators from the U.S. as well as our European and Japanese partners. We use accelerator facilities at the Brookhaven National Laboratory, Loma Linda University and Los Alamos National Laboratory that generate high energy charged particles and neutrons to simulate cosmic radiation and solar particle events. The research using cultured cells and animals concentrates on damage and repair from the level of DNA to organ tissues, due to exposure to simulated space radiation exposure, that contribute to the induction of leukemia and solid tumors in most major tissues such as lung, colon, liver and breast. The goal of the research is to develop a mathematical model that can predict cancer morbidity and mortality risks with sufficient accuracy for a given space mission.

    Cancer control is a long-term work. Cancer research and intervention really need the support of cohort study. In the recent years, more and more cohort studies on cancer control were conducted in China along with the increased ability of scientific research in China. Since 2010, Cancer Hospital, Chinese Academy of Medical Sciences, collaborated with Lanzhou University and the Worker' s Hospital of Jinchuan Group Company Limited, have carried out a large-scale cohort study on cancer, which covered a population of more than 50 000 called " Jinchang cohort". Since 2012, a National Key Public Health Project, "cancer screening in urban China" , has been conducted in Jinchang, which strengthened the Jinchang cohort study. Based on the Jinchang cohort study, historical cohort study, cross-sectional study and prospective cohort study have been conducted, which would provide a lot of evidence for the cancer control in China.

    A diet high in sugars may promote colorectal carcinogenesis, but it remains uncertain whether high intake of sugars or sucrose confers increased risk of colorectal cancer. The authors investigated the associations of sugars and sucrose intake with colorectal cancer risk in a community-based case-control study in Japan. The study subjects comprised 816 incident cases of colorectal cancer and 815 community controls. Consumption frequencies and portion sizes of 148 food and beverage items were ascertained by a computer-assisted interview. The authors used the consumption of 29 food items to estimate sugars and sucrose intake. The odds ratios of colorectal cancer risk according to intake categories were obtained using a logistic regression model with adjustment for potential confounding variables. Overall, intakes of sugars and sucrose were not related to colorectal cancer risk either in men or women. The association between sugars intake and colorectal cancer risk differed by smoking status and alcohol use in men, but not in women. In men, sugars intake tended to be associated with colorectal cancer risk inversely among never-smokers and positively among male ever-smokers (interaction p=0.01). Sugars intake was associated with an increased risk among men with no alcohol consumption, but was unrelated to the risk among male alcohol drinkers (interaction p=0.02). Body mass index did not modify the association with sugars intake in either men or women. Sugars intake was associated with increased risk of colorectal cancer among smokers and non-alcohol drinkers in men selectively.

    Cancer cervix is the leading cause of cancer deaths in females in developing countries and one in five women suffering from cervical cancer lives in India. The aim of this study is to determine the awareness about cervical cancer and Pap smear among nurses working in a tertiary care institute. Study Setting and Design: Cross-sectional survey in a tertiary care institute. Nurses working at our institute excluding those who have worked or working in the Obstetrics and Gynecology department were provided with a pre-designed questionnaire testing their knowledge about cervical cancer. Approximately, 86% were aware about cancer cervix and 69% were aware of a pre-cancerous stage. 42.3% were not aware of any risk factor and 27.6% were not aware of any symptom of cancer cervix. 86.2% were aware about Pap smear, but only 58.6% were aware that facilities of Pap smear were available at our hospital. Knowledge about cervical cancer and awareness of Pap smear as screening test was inadequate in nursing staff. Awareness programs about cervical cancer and screening are needed to increase awareness for this preventable condition. There is a need to arrange reorientation programs to sensitize nurses and establish cytology clinics to offer facilities for easily accessible and affordable screening.

    Full Text Available Background: Symptomatic bacteraemia, is a frequent condition among cancer patients with a significant morbidity and mortality all over the world. Objectives: The aim of this study was to determine the burden of enteric pathogens causing bacteremia among cancer patients. Patients and Methods: Ten ml blood samples were withdrawn from the cancer patients under aseptic conditions. The blood specimens were added to the blood culture bottles and incubated at 37°C. The bacterial isolates from these samples were identified by routine biochemical reactions. Results: During the study period, 68 blood samples from cancer patients were analyzed for bacteremia. Of these patients, six were female (08/82% and 62 were male (91.18%; with age ranging from under 40 years to 85 years old (mean, 63 years. Gastro-intestinal cancer and cancers of head and neck were the most frequent cancer types in the studied group, accounting for 51 (75% and 15 (22.1% cases, respectively. The mean weight of patients was 69.18 Kg (range: 49-100 Kg. Similarly, the mean length of hospital stay was 8 days (range: 4-12 days. Positive blood cultures were detected in only 12 (17.65% and 11 (91.7% blood specimens from the Cancer Institute, Tehran, compared with one (08.33% from Shahid Kamali hospital, Karaj. From these patients, 15 bacteria were isolated; E. coli alone outnumbered other species and accounted for 33.33% of the episodes of bacteremia. Conclusions: In conclusion, our investigation revealed that cancers of GI tract are the most common cancer types causing bacteremia and also we identified that most common bacteria causing bacteremia in Cancer Institute, Tehran and Shahid Kamali Hospital, Karaj, are E. coli and S. aureus

    In our country breast cancer represents a major health problem. Only 45% of all population has access to health services, the consequence is delay in diagnosis and treatment. In Mexico, 66% of all new cases of breast cancer are diagnosed in locally advanced stages. From May 2007 the Health System Protection Against Catastrophic Expenses, called Seguro Popular (SP), breast cancer was included in covering the treatment of this neoplasm in any patient without access to social security. To evaluate the results and impact of SP in the adjuvant and neoadjuvant treatment of a group of patients diagnosed with breast cancer at an institution of national reference. We analyzed a group of 259 patients in stages (I-IIIC). The clinical stages I and II (55 patients) were treated with adjuvant chemotherapy FAC -T (fluorouracil 500 mg/m2, adriamycin 50 mg/m2 and cyclophosphamide 500 mg/m2 (FAC) followed by 12 weeks of paclitaxel 80 mg/m2 +/- trastuzumab loading dose of 4 mg/kg followed by 2 mg/kg); 204 patients in locally advanced stages (IIB-IIIC) received FAC-T +/- trastuzumab followed by surgery. Adjuvant treatment consisted of endocrine therapy for hormone-sensitive patients and radiotherapy 50 cGy according to international standards. The age at diagnosis was 47 years (range 23-68). 80% of them were locally advanced stages (IIB-IIIC) and were treated in a neoadjuvant setting, 20% was in early stages, treated with surgery and adjuvant chemotherapy The disease-free survival and overall survival at 30 months was 85.7 and 90% respectively. Overall pathologic complete response was obtained in 15% of cases. In the subgroup analysis showed that 41% of patients HER2 (+), 29% of triple-negative patients and 9% of hormone-sensitive tumors achieved complete pathological response (p = 0.0001). This is the first analysis of efficacy of adjuvant and neoadjuvant treatment in breast cancer since the introduction of popular secure non-entitled population. It is clear that treatment efficacy

    The purpose of this study was to evaluate the treatment outcomes of stereotactic body radiotherapy (SBRT) for Stage I small-cell lung cancer (SCLC). From April 2003 to September 2009, a total of eight patients with Stage I SCLC were treated with SBRT in our institution. In all patients, the lung tumors were proven as SCLC pathologically. The patients' ages were 58-84 years (median: 74). The T-stage of the primary tumor was T1a in two, T1b in two and T2a in four patients. Six of the patients were inoperable because of poor cardiac and/or pulmonary function, and two patients refused surgery. SBRT was given using 7-8 non-coplanar beams with 48 Gy in four fractions. Six of the eight patients received 3-4 cycles of chemotherapy using carboplatin (CBDCA) + etoposide (VP-16) or cisplatin (CDDP) + irinotecan (CPT-11). The follow-up period for all patients was 6-60 months (median: 32). Six patients were still alive without any recurrence. One patient died from this disease and one died from another disease. The overall and disease-specific survival rate at three years was 72% and 86%, respectively. There were no patients with local progression of the lesion targeted by SBRT. Only one patient had nodal recurrence in the mediastinum at 12 months after treatment. The progression-free survival rate was 71%. No Grade 2 or higher SBRT-related toxicities were observed. SBRT plus chemotherapy could be an alternative to surgery with chemotherapy for inoperable patients with Stage I small-cell lung cancer. However, further investigation is needed using a large series of patients. (author)

    The National Cancer Institute's Skin Cancer Intervention across the Cancer Control Continuum model was developed to summarize research and identify gaps concerning skin cancer interventions. We conducted a mapping review to characterize whether behavioral interventions addressing skin cancer prevention and control from 2000 to 2015 included (1) technology, (2) environmental manipulations (policy and/or built environment), and (3) a theoretical basis. We included 86 studies with a randomized controlled or quasi-experimental design that targeted behavioral intervention in skin cancer for children and/or adults; seven of these were dissemination or implementation studies. Of the interventions described in the remaining 79 articles, 57 promoted only prevention behaviors (e.g., ultraviolet radiation protection), five promoted only detection (e.g., skin examinations), 10 promoted both prevention and detection, and seven focused on survivorship. Of the 79 non-dissemination studies, two-thirds used some type of technology (n=52; 65.8%). Technology specific to skin cancer was infrequently used: UVR photography was used in 15.2% of studies (n=12), reflectance spectroscopy was used in 12.7% (n=10), and dermatoscopes (n=1) and dosimeters (n=2) were each used in less than 3%. Ten studies (12.7%) targeted the built environment. Fifty-two (65.8%) of the studies included theory-based interventions. The most common theories were Social Cognitive Theory (n=20; 25.3%), Health Belief Model (n=17; 21.5%), and the Theory of Planned Behavior/Reasoned Action (n=12; 15.2%). Results suggest that skin cancer specific technology and environmental manipulations are underutilized in skin cancer behavioral interventions. We discuss implications of these results for researchers developing skin cancer behavioral interventions. Copyright © 2017. Published by Elsevier Inc.

    Model systems for oral cancer research have progressed from tumor epithelial cell cultures to in vivo systems that mimic oral cancer genetics, pathological characteristics, and tumor-stroma interactions of oral cancer patients. In the era of cancer immunotherapy, it is imperative to use model systems to test oral cancer prevention and therapeutic interventions in the presence of an immune system and to discover mechanisms of stromal contributions to oral cancer carcinogenesis. Here, we review in vivo mouse model systems commonly used for studying oral cancer and discuss the impact these models are having in advancing basic mechanisms, chemoprevention, and therapeutic intervention of oral cancer while highlighting recent discoveries concerning the role of immune cells in oral cancer. Improvements to in vivo model systems that highly recapitulate human oral cancer hold the key to identifying features of oral cancer initiation, progression, and invasion as well as molecular and cellular targets for prevention, therapeutic response, and immunotherapy development.

    Full Text Available Introduction: The phantom limb pain (PLP and phantom limb sensation (PLS are very common among amputated cancer patients, and they lead to considerable morbidity. In spite of this, there is a lack of epidemiological data of this phenomenon among the Asian population. This study was done to provide the data from Indian population. Methods: The prevalence of PLP, stump pain (SP, and PLS was prospectively analyzed from the amputated cancer patients over a period of 2 years in Dr. B.R.A. Institute Rotary Cancer Hospital, All India Institute of Medical Sciences, New Delhi. The risk factors and the impact of phantom phenomenon on patients were also noted. Results: The prevalence of PLP was 41% at 3 and 12 months and 45.3% at 6 months, whereas that of SP and PLS was 14.4% and 71.2% at 3 months, 18.75% and 37.1% at 6 months, 15.8% and 32.4% at 12 months, respectively. There was higher prevalence of PLP and PLS among the patients with history of preamputation pain, smoking with proximal level of amputation, receiving general anesthesia, receiving intravenous (IV opioid postoperative analgesia, and developing neuroma or infection. Conclusion: The prevalence of PLP and PLS was higher among the cancer amputees as compared to SP, and a few risk factors responsible for their higher prevalence were found in our study. The PLP and PLS lead to considerable morbidity in terms of sleep disturbance and depression.

  1. The WISDOM Study: breaking the deadlock in the breast cancer screening debate.

    Esserman, Laura J

    2017-01-01

    There are few medical issues that have generated as much controversy as screening for breast cancer. In science, controversy often stimulates innovation; however, the intensely divisive debate over mammographic screening has had the opposite effect and has stifled progress. The same two questions-whether it is better to screen annually or bi-annually, and whether women are best served by beginning screening at 40 or some later age-have been debated for 20 years, based on data generated three to four decades ago. The controversy has continued largely because our current approach to screening assumes all women have the same risk for the same type of breast cancer. In fact, we now know that cancers vary tremendously in terms of timing of onset, rate of growth, and probability of metastasis. In an era of personalized medicine, we have the opportunity to investigate tailored screening based on a woman's specific risk for a specific tumor type, generating new data that can inform best practices rather than to continue the rancorous debate. It is time to move from debate to wisdom by asking new questions and generating new knowledge. The WISDOM Study (Women Informed to Screen Depending On Measures of risk) is a pragmatic, adaptive, randomized clinical trial comparing a comprehensive risk-based, or personalized approach to traditional annual breast cancer screening. The multicenter trial will enroll 100,000 women, powered for a primary endpoint of non-inferiority with respect to the number of late stage cancers detected. The trial will determine whether screening based on personalized risk is as safe, less morbid, preferred by women, will facilitate prevention for those most likely to benefit, and adapt as we learn who is at risk for what kind of cancer. Funded by the Patient Centered Outcomes Research Institute, WISDOM is the product of a multi-year stakeholder engagement process that has brought together consumers, advocates, primary care physicians, specialists, policy

    Few studies have addressed the relation between dietary patterns and colorectal cancer in Japan. We investigated dietary patterns in relation to colorectal cancer risk in a community-based case-control study. The association with dietary patterns was also examined for different sites of colorectal cancer. Data were derived from the Fukuoka Colorectal Cancer Study, including 800 cases and 775 controls interviewed from September 2000 to December 2003. The cases were admitted to one of the participating hospitals for the first surgical treatment during this period. We identified dietary patterns using principal component analysis of intakes of twenty-nine items of food groups and specific foods. Quartile categories of each dietary pattern were used, and non-dietary lifestyle factors and total energy intake were adjusted for in the analysis. We identified three dietary patterns: prudent, high-fat and light-meal patterns. The prudent dietary pattern characterised by high intakes of vegetables, fruits, seafoods and soya foods showed a nearly significant protective association with the overall risk of colorectal cancer (trend P = 0.054), and it was statistically significantly related to a decreased risk of distal colon cancer (trend P = 0.002), but not to that of either proximal colon or rectal cancer. The high-fat and light-meal dietary patterns were not materially related to the overall or site-specific risk of colorectal cancer. In summary, a prudent dietary pattern was associated with a decreased risk of colorectal cancer, especially with that of distal colon cancer, in a fairly large case-control study in Japan.

However, the attendance of cervical cancer screening was reported to be low among immigrant women. For this reason, we conducted a qualitative study to obtain better insight into perceived barriers and challenges to cervical cancer screening among Somali and Pakistani women in the Oslo region. A convenient sample of 35 (18 Pakistani, 17 Somali women were recruited for the study in collaboration with Somali and Pakistani community partners. Focus group discussions were used to explore barriers and facilitators to cervical cancer screening, whereas the Ecological Model was used as the framework for the study. The study found three levels of barriers to cervical cancer screening. The individual level included a lack of understanding of the benefits of the screening. The sociocultural level included the stigma attached to the disease and the belief that women who are unmarried are sexually inactive. The system-related level included a lack of trust toward the health care system. Based on the study results, and using a common denominator approach for the immigrant groups included, the study recommends three communication strategies with the potential to improve women’s participation in cervical cancer screening: 1 in-person communication and information material at health centers; 2 verbal communication with women through seminars and workshops to educate them about their risk of cancer and the importance of screening and 3 the initiation of better recall

    Gastric cancer can be classified into two categories based on the absence or presence of symptoms at diagnosis. Differences in clinicopathological features and prognoses between asymptomatic gastric cancer (ACG) and symptomatic gastric cancer (SGC) can be used to inform diagnosis strategies and ultimately improve survival rates. All cases of gastric cancer (239 AGC, 323 SGC) diagnosed in our hospital between 1997 and 1999 were used in this study. ACG patients showed significantly higher frequency of males, cases of early cancer, cases found by a mass screening program, cases treated by endoscopic resection, cases treated by curative operation, cases of type 0 macroscopic finding, cases of histologically-differentiated type, and stage I cases. By contrast, SGC patients showed significantly higher numbers of cases treated by chemotherapy alone or best support care, cases of type 2, 3, and 4 macroscopic findings, cases occupying the whole stomach, and cases of stage II, III, IV. Statistically significant differences were also found for the 5-year survival rate (83.3% in AGC, 41.2% in SGC), the incidence of early cancer (90.1% in AGC, 83.7% in SGC), and for advanced cancer (38.7% in AGC, 22.7% in SGC). The higher incidence of advanced cases in SGC than in AGC (40.0% vs. 13.0%), coupled with the low 5-year survival rate of advanced SGC (22.7%), provides strong evidence of the importance of diagnosing gastric cancer during its asymptomatic period.

    Full Text Available Background. The biomedical care for cancer has not been complemented by psychosocial progressions in cancer care. Objectives. To find the prevalence of anxiety and depression amongst cancer patients in a hospital setting. Design and Setting. This cross-sectional study was conducted at the tertiary care hospitals Shifa International Hospital Islamabad and Nuclear Medicine, Oncology, and Radiotherapy Institute [NORI]. Patients and Methods. 300 patients were interviewed from both the outpatient and inpatient department using The Aga Khan University Anxiety and Depression Scale (AKUADS. Main Outcome Measures. Using a score of 20 and above on the AKUADS, 146 (48.7% patients were suffering from anxiety and depression. Results. When cross tabulation was done between different factors and the cancer patients with anxiety and depression, the following factors were found out to be significant with associated p value < 0.05: education of the patient, presence of cancer in the family, the severity of pain, and the patient’s awareness of his anxiety and depression. Out of 143 (47.7% uneducated patients, 85 (59.4% were depressed, hence making it the highest educational category suffering from depression and anxiety. Conclusion. The prevalence of anxiety and depression amongst cancer patients was high showing that importance should be given to screening and counseling cancer patients for anxiety and depression, to help them cope with cancer as a disease and its impact on their mental wellbeing. Limitations. The frequency of female patients in our research was higher than those of male patients.

    Patient-centered communication (PCC) is a critical element of patient-centered care, which the Institute of Medicine (Committee on Quality of Health Care in America, 2001) promulgates as essential to improving healthcare delivery. Consequently, the US National Cancer Institute's Strategic Plan for Leading the Nation (2006) calls for assessing the delivery of PCC in cancer care. However, no comprehensive measure of PCC exists, and stakeholders continue to embrace different conceptualizations and assumptions about how to measure it. Our approach was grounded in the PCC conceptual framework presented in a recent US National Cancer Institute monograph (Epstein & Street, 2007). In this study, we developed a comprehensive inventory of domains and subdomains for PCC by reviewing relevant literature and theories, interviewing a limited number of cancer patients, and consulting experts. The resulting measurement domains are organized under the six core functions specified in the PCC conceptual framework: exchanging information, fostering healing relationships, recognizing and responding to emotions, managing uncertainty, making decisions, and enabling patient self-management. These domains represent a promising platform for operationalizing the complicated PCC construct. Although this study focused specifically on cancer care, the PCC measurements are relevant to other clinical contexts and illnesses, given that patient-centered care is a goal across all healthcare. Finally, we discuss considerations for developing PCC measures for research, quality assessment, and surveillance purposes.

    The Open Archive Initiative (OAI) refers to a movement started around the '90 s to guarantee free access to scientific information by removing the barriers to research results, especially those related to the ever increasing journal subscription prices. This new paradigm has reshaped the scholarly communication system and is closely connected to the build up of institutional repositories (IRs) conceived to the benefit of scientists and research bodies as a means to keep possession of their own literary production. The IRs are high-value tools which permit authors to gain visibility by enabling rapid access to scientific material (not only publications) thus increasing impact (citation rate) and permitting a multidimensional assessment of research findings. A survey was conducted in March 2010 to mainly explore the managing system in use for archiving the research finding adopted by the Italian Scientific Institutes for Research, Hospitalization and Health Care (IRCCS) of the oncology area within the Italian National Health Service (Servizio Sanitario Nazionale, SSN). They were asked to respond to a questionnaire intended to collect data about institutional archives, metadata formats and posting of full-text documents. The enquiry concerned also the perceived role of the institutional repository DSpace ISS, built up by the Istituto Superiore di Sanità (ISS) and based on a XML scheme for encoding metadata. Such a repository aims at acting as a unique reference point for the biomedical information produced by the Italian research institutions. An in-depth analysis has also been performed on the collection of information material addressed to patients produced by the institutions surveyed. The survey respondents were 6 out of 9. The results reveal the use of different practices and standard among the institutions concerning: the type of documentation collected, the software adopted, the use and format of metadata and the conditions of accessibility to the IRs.

    Full Text Available BACKGROUND Cancer is one of the leading cause of death both in developed and developing countries. In India, it accounts for 0.3 million deaths per year. Cancers of lung, GIT and oral cancers dominated among men while breast, cervix, ovary and oral cavity were commonest cancer seen in women. Among the gastrointestinal cancers, cancers of the oesophagus, stomach, colon, rectum and liver cancers were commonest. The aim of the study is to evaluate the incidence of the various GIT cancers in a tertiary hospital of Coastal Andhra when compared to other studies. MATERIALS AND METHODS In this retrospective study, a total of 509 health records of patients affected by cancers were studied and relevant details noted. RESULTS A total of 509 cancer cases were reported in this period of 18 months (January 2016 - June 2017 of which 85 cases (16.3% were of Gastrointestinal (GIT cancers. The age group between 40 and 60 recorded the maximum incidence of 47 cancers (55.1%. The incidence of gastrointestinal cancers were significantly higher in the men (56 cases (65.8% than the women (29 cases (34.11%. The commonest site of GIT cancers was the colorectal region (30 cases (35.7%. The most common type of cancer seen was adenocarcinoma seen in 73 cases (85.8%. CONCLUSION Public education and awareness for the warning symptoms should be increased to prevent reduction of the life span and health caused by the gastrointestinal cancers with intense awareness drive using various means including social media undertaken to educate the public regarding the warning symptoms and screening of such group for GIT cancers.

    In 2001, the National Institute for Health Research Cancer Research Network (NCRN) was established, leading to a rapid increase in clinical research activity across the English NHS. Using colorectal cancer (CRC) as an example, we test the hypothesis that high, sustained hospital-level participation in interventional clinical trials improves outcomes for all patients with CRC managed in those research-intensive hospitals. Data for patients diagnosed with CRC in England in 2001-2008 (n=209 968) were linked with data on accrual to NCRN CRC studies (n=30 998). Hospital Trusts were categorised by the proportion of patients accrued to interventional studies annually. Multivariable models investigated the relationship between 30-day postoperative mortality and 5-year survival and the level and duration of study participation. Most of the Trusts achieving high participation were district general hospitals and the effects were not limited to cancer 'centres of excellence', although such centres do make substantial contributions. Patients treated in Trusts with high research participation (≥16%) in their year of diagnosis had lower postoperative mortality (presearch participation, with a reduction in postoperative mortality of 1.5% (6.5%-5%, pstudies for all patients with CRC treated in the hospital study participants. Improvement precedes and increases with the level and years of sustained participation. Published by the BMJ Publishing Group Limited.

    Background: Gastric cancer is one of the most lethal tumors in the Chilean population. Aim: To report the results of adjuvant chemoradiotherapy in advanced gastric cancer. Material and Methods: Review of medical records of patients with locoregionally advanced gastric cancer, subjected to a curative resection and treated with adjuvant chemoradiotherapy. The treatment was based on he INT 0116/SSWOG protocol, which includes 5-fluorouracil as a single agent. Patients were followed for a median of 58 months. Results: The records of 168 patients (99 men) treated between 2004 nd 2011, were reviewed. Median survival as 41 months. Median lapses between surgery and onset of chemo and radiotherapy were 12 and 17 weeks, respectively. Overall three and five years survival was 53 and 41%, respectively. On multivariate analysis the factors associated with a lower survival were an antral location of the tumor, presence of signet ring cells and more than 5 involved lymph nodes. Conclusions: Three and five years survival of gastric cancer patients subjected to adjuvant chemoradiotherapy was 53 and 41% respectively.These results are similar to those reported elsewhere

    Inflammation has been hypothesized to increase the risk of cancer development as an initiator or promoter, yet no large-scale study of inherited variation across cancer sites has been conducted. We conducted a cross-cancer genomic analysis for the inflammation pathway based on 48 genome-wide association studies within the National Cancer Institute GAME-ON Network across five common cancer sites, with a total of 64 591 cancer patients and 74 467 control patients. Subset-based meta-analysis was used to account for possible disease heterogeneity, and hierarchical modeling was employed to estimate the effect of the subcomponents within the inflammation pathway. The network was visualized by enrichment map. All statistical tests were two-sided. We identified three pleiotropic loci within the inflammation pathway, including one novel locus in Ch12q24 encoding SH2B3 (rs3184504), which reached GWAS significance with a P value of 1.78 x 10(-8), and it showed an association with lung cancer (P = 2.01 x 10(-6)), colorectal cancer (GECCO P = 6.72x10(-6); CORECT P = 3.32x10(-5)), and breast cancer (P = .009). We also identified five key subpathway components with genetic variants that are relevant for the risk of these five cancer sites: inflammatory response for colorectal cancer (P = .006), inflammation related cell cycle gene for lung cancer (P = 1.35x10(-6)), and activation of immune response for ovarian cancer (P = .009). In addition, sequence variations in immune system development played a role in breast cancer etiology (P = .001) and innate immune response was involved in the risk of both colorectal (P = .022) and ovarian cancer (P = .003). Genetic variations in inflammation and its related subpathway components are keys to the development of lung, colorectal, ovary, and breast cancer, including SH2B3, which is associated with lung, colorectal, and breast cancer. © The Author 2015.

    In November of 1982 the Colorado Department of Health completed an epidemiologic investigation of leukemia, multiple myeloma, and cancers of the lung, stomach, pancreas and colon in Mesa County, Colorado for the years 1970 to 1979. This investigation was performed in response to a concern that the presence of uranium mill tailings in some Mesa County homes presents a potential cancer hazard. The results of the investigation show that the incidence of multiple myeloma, colon, stomach and pancreatic cancer are not above expected rates. The incidence of leukemia is not above expected rates for the entire study period, 1970 to 1979. The incidence of lung cancer appears elevated when compared to the The Third National Cancer Survey data for Colorado but lower than expected when compared to Surveillance, Epidemiology and End Results data. To further examine the leukemia and lung cancer incidence findings, a case/control study was conducted. The controls consisted of colon, stomach and pancreatic cancer cases. The results of the leukemia case/control analysis show no association with the radiation exposure variables: occupational radiation exposure; uranium mining exposure; having ever lived in a type A home (uranium tailings home); and radiation therapy. The lung cancer case/control analysis shows a significant association with only the radiation exposure variable, uranium mining history, indicating cases were more likely to have been uranium miners than were controls. As with leukemia, the study found no association between lung cancer and living in a uranium mill tailings home. The relatively low radiation exposures typical of type A homes and the small number of persons exposed make it very difficult to establish, by epidemiologic methods, that a risk exists

    Full Text Available Context: Training programs for volunteers prior to their working in palliative care are well-established in India. However, few studies report on continuing professional development programs for this group. Aims: To conduct a preliminary assessment of educational needs of volunteers working in palliative care for developing a structured formal continuing professional development program for this group. Settings and Design: Cross-sectional observational study conducted in the Department of Palliative Medicine of a tertiary care cancer institute in India. Materials and Methods: Participant volunteers completed a questionnaire, noting previous training, years of experience, and a comprehensive list of topics for inclusion in this program, rated in order of importance according to them. Statistical Analysis Used: Descriptive statistics for overall data and Chi-square tests for categorical variables for group comparisons were applied using Statistical Package for Social Sciences version 18. Results: Fourteen out of 17 volunteers completed the questionnaire, seven having 5-10-years experience in working in palliative care. A need for continuing professional development program was felt by all participants. Communication skills, more for children and elderly specific issues were given highest priority. Spiritual-existential aspects and self-care were rated lower in importance than psychological, physical, and social aspects in palliative care. More experienced volunteers (>5 years of experience felt the need for self-care as a topic in the program than those with less (<5-years experience ( P < 0.05. Conclusions: Understanding palliative care volunteers′ educational needs is essential for developing a structured formal continuing professional development program and should include self-care as a significant component.

Following accumulating data revealing abnormal elevated expression levels of key stemness factors, like Nanog, Oct4, and Sox2, in several types of cancer stem cells; the importance and therapeutic potential of targeting these stemness regulators in cancers has turned to research focus. Nanog determines cell fate in both embryonic and cancer stem cells; activating Nanog at an inappropriate time would result in cancer stem cells rather than normal pluripotent stem cells or differentiated somatic cells. Upregulated Nanog is correlated with poor survival outcome of patients with various types of cancer. The discoveries of downstream regulatory pathways directly or indirectly mediated by Nanog indicate that Nanog regulates several aspects of cancer development such as tumor cell proliferation, self-renewal, motility, epithelial-mesenchymal transition, immune evasion, and drug-resistance, which are all defined features for cancer stem cells. The current review paper illustrates the central role of Nanog in the regulatory networks of cancer malignant development and stemness acquirement, as well as in the communication between cancer cells and the surrounding stroma. Though a more defined model is needed to test the

    Discovery of disease biomarkers for cancer is a leading focus of early detection. The National Cancer Institute created a network of collaborating institutions focused on the discovery and validation of cancer biomarkers called the Early Detection Research Network (EDRN). Informatics plays a key role in enabling a virtual knowledge environment that provides scientists real time access to distributed data sets located at research institutions across the nation. The distributed and heterogeneous nature of the collaboration makes data sharing across institutions very difficult. EDRN has developed a comprehensive informatics effort focused on developing a national infrastructure enabling seamless access, sharing and discovery of science data resources across all EDRN sites. This paper will discuss the EDRN knowledge system architecture, its objectives and its accomplishments.

    Objective: Breast cancer is a worldwide public health issue and most common cancer diagnosed among women including China, where advanced stages at diagnosis appears to be increasing and an ever-rising incidence twice as fast as global rates. The study was conducted to describe the awareness of breast cancer and associated factors among care giver women in tertiary Cancer Hospital, China. Methods: Institutional based cross-sectional study was conducted among 261 women selected by systematic random sampling. Information provided by the participants was converted into awareness scores for analysis using SPSS version 23. Awareness scores were dichotomized in to ‘good awareness and ‘poor awareness’ taking median score=11 as the cut-off point. Data analysis was performed using the binary logistic regression. A p-value of awareness. Breast lump was the most commonly known symptom of cancer by 61.7% of the respondents. Slightly more than half of the study participants acknowledged having a past history of breast cancer, drinking alcohol and having close relative with breast cancer as potential risk factors for breast cancer (63.6%, 58.6%, and 55.6% respectively). Nevertheless, a vast majority of the study participants were unable to appreciate modifiable risk factors of the disease. More than half of the participants had never/rarely checked their breasts and all of the participants wrongly answered breast cancer knowledge age related risk. Awareness level was significantly associated with entertainment preference (OR=3.57; 95%CI=1.71, 7.44) and residence setting areas (OR=2.4; 95%CI=1.04, 5.69). Conclusion: The study indicated suboptimal awareness while entertainment preference and residence setting were significantly associated with awareness level. Public awareness campaigns should be made by dissemination of information about breast cancer through health education and printed Medias with great emphases on women living in rural areas.

    Age adjusted incidence rate of lung cancer in India ranges from 7.4 to 13.1 per 100,000 among males and 3.9 to 5.8 per 100,000 among females. The factors affecting survival in lung cancer patients in India are not fully understood. The current study was undertaken to evaluate the factors affecting survival in patients diagnosed with lung cancer attending a tertiary care cancer institute in Bangalore, Karnataka, India. Consecutive patients with primary lung cancer attending Bangalore Institute of Oncology, a tertiary care centre at Bangalore, between 2006 and 2009 were included. Demographic, clinical, radiological data were collected retrospectively from the medical records. A total of 170 consecutive subjects (128 males, 42 females) diagnosed to have lung cancer; 151 non-small cell lung cancer (NSCLC) and 19 small cell lung cancer (SCLC) were included. A higher proportion of never-smokers (54.1%) were observed, mostly presenting below the age of 60 yr. Most subjects were in stage IV and III at the time of diagnosis. More than 50 per cent of patients presented with late stage lung cancer even though the duration of symptoms is less than 2 months. The 30-month overall survival rates for smokers and never-smokers were 32 and 49 per cent, respectively. No significant differences were observed in 30 month survival based on age at presentation, gender and type of lung cancer. Cox proportional hazards model identified never-smokers and duration of symptoms less than 1 month as factors adversely affecting survival. Our results showed that lung cancer in Indians involved younger subjects and associated with poorer survival as compared to other ethnic population. Studies on large sample need to be done to evaluate risk factors in lung cancer patients.

    Non-atypical papillomas (NAPs) diagnosed on core needle biopsy (CNB) frequently undergo surgical excision due to highly variable upstaging rates. The purpose of this study is to document our dual-institution upgrade rates of NAPs diagnosed on core needle biopsy and review the upgrade rates reported in the literature. Following IRB approval, CNB results from Duke University (7/1/2004-6/30/2014) and the University of North Carolina Chapel Hill (1/1/04-6/30/2013) were reviewed to identify non-atypical papillomas. All cases with surgical excision or 2 years of imaging follow up were included. In addition, a literature review identified 60 published studies on upgrades of NAPs diagnosed at CNB. Cases in our cohort and the published literature were reviewed for confounding factors: [1] missing radiologic-pathologic concordance and/or discordance, [2] papillomas included with high-risk lesions, [3] high risk lesions counted as upgrades, [4] review by a nonspecialized breast pathologist, and [5] cancer incidentally detected. Of the 388 CNBs in our dual-institution cohort, 136 (35%) patients underwent surgical excision and 252 (65%) patients had imaging follow up. After controlling for confounders, no cancers (0/388) were found at surgical excision or during follow up imaging. The literature review upstaging rate was 4.0% (166/4157) but 1.8% (4/227) after excluding studies with confounders. The combined upstaging rate from the literature and this study was 0.6% (4/615). The upstaging rate for CNB diagnosed NAPs was 0% in our cohort and 0.6% overall after adjusting for confounders. This low rate does not warrant reflexive surgical excision and diagnostic imaging follow up should be discretionary. Copyright © 2018 Elsevier Inc. All rights reserved.

    Despite advances in early detection and effective treatment, cancer remains one of the most feared diseases. Among the most common side effects of cancer and treatments for cancer are pain, depression, and fatigue. Although research is producing increasingly hopeful insights into the causes and cures for cancer, efforts to manage the side effects of the disease and its treatments have not kept pace. The challenge that faces us is how to increase awareness of the importance of recognizing and actively addressing cancer-related distress. The National Institutes of Health (NIH) convened a State-of-the-Science Conference on Symptom Management in Cancer: Pain, Depression, and Fatigue to examine the current state of knowledge regarding the management of pain, depression, and fatigue in individuals with cancer and to identify directions for future research. Specifically, the conference examined how to identify individuals who are at risk for cancer-related pain, depression, and/or fatigue; what treatments work best to address these symptoms when they occur; and what is the best way to deliver interventions across the continuum of care. STATE-OF-THE-SCIENCE PROCESS: A non-advocate, non-Federal, 14-member panel of experts representing the fields of oncology, radiology, psychology, nursing, public health, social work, and epidemiology prepared the statement. In addition, 24 experts in medical oncology, geriatrics, pharmacology, psychology, and neurology presented data to the panel and to the conference audience during the first 1.5 days of the conference. The panel then prepared its statement, addressing the five predetermined questions and drawing on submitted literature, the speakers' presentations, and discussions held at the conference. The statement was presented to the conference audience, followed by a press conference to allow the panel to respond to questions from the media. After its release at the conference, the draft statement was made available on the Internet

    Treatment results were reviewed in 473 consecutively staged and treated patients at the National Cancer Institute over a 22-year period from 1953 to 1975. Responses correlated with histologic pattern and stage of disease. Complete responses to radiotherapy were frequent in nodular lymphoma patients. Similar treatment regimens were less effective in diffuse lymphoma patients. Using chemotherapy or combined modality approaches, complete responses were obtained in a high proportion of advanced nodular disease patients. Patients with nodular lymphoma tend to have higher complete response rates and longer survivals than their counterparts with diffuse histologic types. Patients with nodular lymphocytic lymphoma had a better survival than those with mixed or ''histiocytic'' histologic types. Patients with diffuse well differentiated lymphocytic lymphoma survived significantly longer than patients with other diffuse histologic types. Percentage and prominence of nodularity were not of prognostic significance in those patients with combined nodular and diffuse patterns of disease. When compared by histologic type, patient sex did not appear to be an important prognostic factor. The presence of B-symptoms was associated with a poorer survival in patients with nodular disease and in patients with diffuse disease. Over the years of this study, survival appears to have improved in each histologic subtype except diffuse poorly differentiated lymphoma

    The objective of this study will be to synthesize the epidemiological evidence and evaluate the validity of the associations between central nervous system disorders and the risk of developing or dying from cancer. We will perform an umbrella review of systematic reviews and conduct updated meta-analyses of observational studies (cohort and case-control) investigating the association between central nervous system disorders and the risk of developing or dying from any cancer or specific types of cancer. Searches involving PubMed/MEDLINE, EMBASE, SCOPUS and Web of Science will be used to identify systematic reviews and meta-analyses of observational studies. In addition, online databases will be checked for observational studies published outside the time frames of previous reviews. Eligible central nervous system disorders will be Alzheimer's disease, anorexia nervosa, amyotrophic lateral sclerosis, autism spectrum disorders, bipolar disorder, depression, Down's syndrome, epilepsy, Huntington's disease, multiple sclerosis, Parkinson's disease and schizophrenia. The primary outcomes will be cancer incidence and cancer mortality in association with a central nervous system disorder. Secondary outcome measures will be site-specific cancer incidence and mortality, respectively. Two reviewers will independently screen references identified by the literature search, as well as potentially relevant full-text articles. Data will be abstracted, and study quality/risk of bias will be appraised by two reviewers independently. Conflicts at all levels of screening and abstraction will be resolved through discussion. Random-effects meta-analyses of primary observational studies will be conducted where appropriate. Parameters for exploring statistical heterogeneity are pre-specified. The World Cancer Research Fund (WCRF)/American Institute for Cancer Research (AICR) criteria and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach will be used

    Full Text Available Abstract Background Over the years awareness and uptake of cervical cancer screening services has remained poor in developing countries. Problems associated with cervical cancer incidence include late reporting, ignorance and cultural issues relating to cervical cancer screening. This study sought to explore the awareness, perception and utilization of cervical cancer screening among women in Ibadan as well as factors that influence utilization. Method This is a qualitative study that utilized Eight Focus Group Discussions to collect information from women in selected health facilities in Ibadan, South West, Nigeria. The 82 participants were purposely recruited from women attending Antenatal clinics in 4 secondary and 4 primary health care facilities after approval was received from the Institutional Review Board in charge of the facilities. The focus group discussions were tape recorded and transcribed verbatim. The transcripts were analyzed into themes. Findings The study provided qualitative information on the awareness, perception of the utilization of cervical cancer screening services among women in Ibadan. Participants were mainly married women (92.7%, mean age =27.6, SD =4.5, mainly traders (39% and from Yoruba ethnic backgrounds (87.8% and had secondary education (39%. The respondents reported not being aware of cervical cancer and were not utilizing the services. Though they did not know what cervical cancer screening entailed or the screening methods, they still believed that it is important since like for other diseases will help in early detection and treatment. The participants were eager to get more information from nurses on cervical cancer about cervical cancer screening. The major factors identified by the women that influence screening utilization were ignorance, Illiteracy, belief in not being at risk, having many contending issues, nonchalant attitude to their health, financial constraint and fear of having a positive result

    Full Text Available Abstract Background Carboplatin/paclitaxel is the chemotherapy of choice for advanced ovarian cancer, both in first line and in platinum-sensitive recurrence. Although a significant proportion of patients have some neurotoxicity during treatment, the long-term outcome of chemotherapy-induced neuropathy has been scantly studied. We retrospectively assessed the prevalence of residual neuropathy in a cohort of patients in clinical remission after first-line carboplatin/paclitaxel for advanced ovarian cancer. Methods 120 patients have been included in this study (101 participating in a multicentre phase III trial evaluating the efficacy of consolidation treatment with topotecan, and 19 treated at the National Cancer Institute of Naples after the end of the trial. All patients received carboplatin (AUC 5 plus paclitaxel (175 mg/m2 every 3 weeks for 6 cycles, completing treatment between 1998 and 2003. Data were collected between May and September 2004. Residual sensory and motor neurotoxicity were coded according to the National Cancer Institute – Common Toxicity Criteria. Results 55 patients (46% did not experience any grade of neurological toxicity during chemotherapy and of these none had signs of neuropathy during follow-up. The other 65 patients (54% had chemotherapy-induced neurotoxicity during treatment and follow-up data are available for 60 of them. Fourteen out of 60 patients (23% referred residual neuropathy at the most recent follow-up visit, after a median follow up of 18 months (range, 7–58 months: 12 patients had grade 1 and 2 patients grade 2 peripheral sensory neuropathy; 3 patients also had grade 1 motor neuropathy. The remaining 46/60 patients (77% had no residual neuropathy at the moment of interview: recovery from neurotoxicity had occurred in the first 2 months after the end of chemotherapy in 22 (37%, between 2 and 6 months in 15 (25%, or after more than 6 months in 9 patients (15%.
