    We studied the mechanism of radiation-induced apoptosis, the factors involved signaling, and the establishment of radiation-resistant cell lines in this study. During the TGF beta-stimulated epithelial mesenchymal transition(EMT), actin rearrangement occurred first and fibronectin matrix assembly followed. These two events were considered independent since cytochalasin-D did not inhibit TGF stimulated matrix assembly and fibronectin supplementation did not induce EMT. During EMT, alpha 5 beta 1 integrin and alpha v integrin have increased but MMP activation was not accompanied, which suggest that induction of extracellular matrix and activation of integrins may be main contributor for the EMT. Serum depriving induced apoptosis of HUVECs was prevented by vascular endothelial growth factor(VEGF) and PMA. The apoptosis prevention by VEGF and PMA were conformed by DNA fragmentation assay. The p53 expression level was down regulated by VEGF and PMA compared with serum deprived HUVECs. However, VEGF and PMA induces c-Myc expression level on these cells. We made the 5 radiation-resistant clones from breast, lung and cervical cancer cells. More than 70%, 100% and 50% increased resistance was detected in breast cancer cells, lung cancer cells, and cervical cells, respectively. We carried out differential display-PCR to clone the radiation-resistant genes. 9 out of 10 genes were analyzed their sequence

    The radioresistant clones was established from human U251 glioblastoma cell line through intermittently exposed to 3 Gy gamma-radiation for six months. Treatment of SNU-16 cells with various doses of radiation, TNF alpha and PMA resulted in a decrease in cell viability. The results prove that cell death of SNU16 is a apoptosis mediated by caspase-3. We have examined the expression of bcl-2 and c-myc in cervical cancer specimens and cervical intraepithelial neoplasia (CIN) to determine the role of coexpression of bcl-3 and c-myc during progression into cervical cancer. The frequent alterations in FHIT expression in many cervical carcinomas and their cell lines suggest that FHIT gene alterations are pla a role in cervical tumorigenesis. According to these correlation between the viability and apoptosis of RD cells, the proper range of the dosage for the investigation of differentiation potency in RD cells was assessed as 1 to 3Gy

    The measuremet of the serum level of squamous cell carcinoma-related antigen (SCC) purified from liver metastasis of cancer of the uterine cervix by an RIA kit is basically evaluated. The results of sensitivity, the recovery test, dilution test and variance test are good enough for clinical application. In gynecological disorders, the possitive rate is high (62 % [29/47]) in patients with cancer of the uterine cervix. Furthermore, the rate and level are related with the clinical staging. The changes of the serum SCC level in irradiated patients with cancer of the uterine cervix were a good reflection of the effectiveness of the treatment. (author)

    In association with clinical study of carbon beam therapy for lung cancer, the basic research for lung cancer and the patients with this disease has been carried out for the past 10 years. With regard to lung damage by the carbon beams, firstly pulmonary function was measured and analyzed for the patients with stage I non-small cell lung cancer. Force expiratory volume in 1 second (FVE 1.0) and TLC (total lung capacity) was found to be reduced significantly at 6 and 12 months after therapy but the reduction rate was a little, which can support the safety of this treatment modality. Secondly, the regional lung damage by the beams was investigated by using correct fusion of CT images with carbon beam dose distribution, diagnostic follow-up CT images and blood flow and ventilation spect images. It demonstrated the graded decrease blood flow by dose and the compensatory increase of blood flow in the adjacent lobe of lung unexposed to irradiation. On the other hand, the biological study of carbon beam effects on lung cancer cells and tumors line was conducted. Firstly, by using 7 or 4 human lung cancer cell line, the radiosensitivity of carbon beams was compared with that of photons by different histological patterns. It was found that there was no essential difference in the sensitivity pattern for lung cancer histology between the carbon beams and photons though the former doubled the later in power. Secondly, by using IA cell lines among them, the dynamic of clonogenic cells (clonogen) in a nude tumor and the changes in its morphology following irradiation was investigated, clarifying that the clonogen proliferating under anoxic or hypoxic conditions played a pivotal role for tumor regrowth and stemmed from the different clone which had been genetically selected and developed under these conditions. The finding of clonogen becomes one of the evidence supporting the superiority of a single-dose radiotherapy to fractionated radiotherapy. (author)

    Marcello Maugeri-Saccà

    2011-01-01

    Full Text Available With the advent of molecular targeted therapies and the development of high-throughput biotechnologies, it has become evident that progress in cancer research is largely due to the creation of multidisciplinary teams able to plan clinical trials supported by appropriate molecular hypotheses. These efforts have culminated in the identification and validation of biomarkers predictive of response, as well as in the generation of more accurate prognostic tools. The identification of cancer stem cells has provided further insights into mechanisms of cancer, and many studies have tried to translate this biological notion into prognostic and predictive information. In this regard, new agents targeting key stemness-related pathways have entered the clinical development, and preliminary data suggested an encouraging antitumor activity.

  20. Basic study of cancer immunity and radiotherapy

    International Nuclear Information System (INIS)

    1978-01-01

    With respect to anti-tumor effect of radiation, antigenicity and involvement of immunity of an individual with cancer were evaluated under both conditions of natural and insufficient immunity. In animal experiments, it is clear that immunity of the host, especially the function of T-cells, has much to do with the curability of cancer by radiotherapy. In some type of human cancer, not only the histological findings in its healing process following x-ray irradiation but a number of clinical and in vitro experimental results strongly suggest the presence of antigenicity of the T-cells, although it is quite little. The experiments made in a combination of human cancer and nude mice showed a possibility of non-T cells being involved in this mechanism irrespective of whether it is specific, non-specific or not having such an important role as T-cells. There are many problems left unsolved. However, radiotherapy of cancer should be undertaken by maintaining or further improving the immunity of the body in order to obtain good results. (Ueda, J.)

    Anemia is the most common hematological abnormality in cancer patients is often under-recognized and undertreated. The pathogenesis of cancer anemia is complex and most of time multifactorial; involving factors related to the tumor itself or its therapy. While anemia can be present in a wide range of symptoms, involing almost every organ, it is beleived that it contributes much to cancer-related-fatigue, one of the most common symptoms in cancer patients. In addition there is increasing evidence to suggest that anemia is an independent factor adversely affecting tumor reponse and patient survival. While blood transfusion was the only option to treat cancer related anemia, the use of recombinant human erythropoietin (rHuEPO) is becomig the new standard of care, more so with the recent studies demonstrating the feasibility of a sigle weekly injection .Things are even getting better with the recent approval of a new form of rHuEPO; Darbepoetin an analogue with a 3-fold longer half-life. In addition to its effects in raising homoglobin, several well controlled studies demonstrated decrease in transfusion requirementsand better qualify of life assessed objectively using standard assesments scales.

  7. Cancer pain management: Basic information for the young pain physicians

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Cancer pain is multifactorial and complex. The impact of cancer pain is devastating, with increased morbidity and poor quality of life, if not treated adequately. Cancer pain management is a challenging task both due to disease process as well as a consequence of treatment-related side-effects. Optimization of analgesia with oral opioids, adjuvant analgesics, and advanced pain management techniques is the key to success for cancer pain. Early access of oral opioid and interventional pain management techniques can overcome the barriers of cancer pain, with improved quality of life. With timely and proper anticancer therapy, opioids, nerve blocks, and other non-invasive techniques like psychosocial care, satisfactory pain relief can be achieved in most of the patients. Although the WHO Analgesic Ladder is effective for more than 80% cancer pain, addition of appropriate adjuvant drugs along with early intervention is needed for improved Quality of Life. Effective cancer pain treatment requires a holistic approach with timely assessment, measurement of pain, pathophysiology involved in causing particular type of pain, and understanding of drugs to relieve pain with timely inclusion of intervention. Careful evaluation of psychosocial and mental components with good communication is necessary. Barriers to cancer pain management should be overcome with an interdisciplinary approach aiming to provide adequate analgesia with minimal side-effects. Management of cancer pain should comprise not only a physical component but also psychosocial and mental components and social need of the patient. With risk-benefit analysis, interventional techniques should be included in an early stage of pain treatment. This article summarizes the need for early and effective pain management strategies, awareness regarding pain control, and barriers of cancer pain.

  9. Endoradiotherapy in cancer treatment--basic concepts and future trends.

    Zoller, Frederic; Eisenhut, Michael; Haberkorn, Uwe; Mier, Walter

    2009-12-25

    Endoradiotherapy represents an alternative therapeutic method in cancer treatment with advantageous features compared to chemotherapy and radiation therapy. Intelligent dose delivery concepts using small drugs, peptides or antibodies as radionuclide carriers enable the verification of a selective accumulation in the tumour lesion and to reduce radiation toxicity for the peripheral organs. The development of endoradiotherapeutic agents, especially chelator-conjugated biomolecules, for example ibritumomab tiuxetan or DOTATOC, gains importance due to the stable complexation of versatile radiometals, such as (90)Y or (177)Lu. The rational design of novel target binding sides and their grafting into a drug scaffold is a highly promising strategy, which may promote further implication in endoradiotherapy. This review highlights the basic concepts of endoradiotherapy and discusses the potential of targeted therapy and the properties of energy-rich particles emitted by radionuclides for tumour therapy.

    2017-11-01

    Cancer-related fatigue (CRF) significantly interferes with usual functioning because of the distressing sense of physical, emotional, and cognitive exhaustion. Assessment of CRF is important and should be performed during the initial cancer diagnosis, throughout cancer treatment, and after treatment using a fatigue scoring scale (mild-severe). The general approach to CRF management applies to cancer survivors at all fatigue levels and includes education, counseling, and other strategies. Nonpharmacologic interventions include psychosocial interventions, exercise, yoga, physically based therapy, dietary management, and sleep therapy. Pharmacologic interventions include psychostimulants. Antidepressants may also benefit when CRF is accompanied by depression. Copyright © 2017 Elsevier Inc. All rights reserved.

    2015-05-01

    Although preclinical work is vital in unraveling the molecular tenets which apply to metformin action in breast cancer, it is by nature unable to capture the host's response to metformin in terms of insulin-mediated effects and related changes in the hormonal and metabolic asset at the systemic level. The latter might sound seemingly paradoxical when considering the inveterate use of metformin in dysmetabolisms and pathologic conditions with underlying hormonal disruption. Bridging the gap between the molecular target and characteristics of breast cancer patients may help lab-based experiments and clinical work converge into one or more well characterized sub-populations instead of a sub optimally selected one. An appropriate patient selection is the main key to the most suitable outcome interpretation and amelioration, in an attempt to meet our patients needs midway between overestimation of benefits and efficacy dilution for any given intervention and/or co-intervention.

  13. Gyroscope precession in special and general relativity from basic principles

    Science.gov (United States)

    Jonsson, Rickard M.

    2007-05-01

    In special relativity a gyroscope that is suspended in a torque-free manner will precess as it is moved along a curved path relative to an inertial frame S. We explain this effect, which is known as Thomas precession, by considering a real grid that moves along with the gyroscope, and that by definition is not rotating as observed from its own momentary inertial rest frame. From the basic properties of the Lorentz transformation we deduce how the form and rotation of the grid (and hence the gyroscope) will evolve relative to S. As an intermediate step we consider how the grid would appear if it were not length contracted along the direction of motion. We show that the uncontracted grid obeys a simple law of rotation. This law simplifies the analysis of spin precession compared to more traditional approaches based on Fermi transport. We also consider gyroscope precession relative to an accelerated reference frame and show that there are extra precession effects that can be explained in a way analogous to the Thomas precession. Although fully relativistically correct, the entire analysis is carried out using three-vectors. By using the equivalence principle the formalism can also be applied to static spacetimes in general relativity. As an example, we calculate the precession of a gyroscope orbiting a static black hole.

    Endoscopic ultrasound (EUS) has become a mainstay in assisting in the diagnosis and staging of pancreatic cancer. In addition, EUS provides a modality to treat chronic pain through celiac plexus neurolysis. Currently, there is growing data and utilization of EUS in more diverse and innovative applications aimed at providing more sophisticated diagnostic, prognostic and therapeutic options for patients with pancreatic cancer. EUS delivery of chemotherapy, viral and biological vectors and fiducial markers may eventually revolutionize the way clinicians approach the care of a patient with pancreatic cancer.

    Full Text Available Background. This paper details the role of different dimensions of health literacy in the relationship between health literacy and cancer-related health behaviours. In particular, Cancer Literacy is studied as an exemplar of a dimension of health literacy beyond basic reading and writing skills. The link between functional health literacy, Cancer Literacy and cancer-related health behaviours is investigated in a sample of Ticino (Switzerland residents (n=639. Design and methods. Detailed data is collected about respondents’ functional health literacy, Cancer Literacy, cancer information seeking behaviour, engagement in cancer preventive behaviours, participation to cancer screenings, and intention to adhere to current screening recommendations. Results. Results confirm the added value of Cancer Literacy – compared to functional health literacy – in explaining people’s cancer information seeking behaviour, their participation to several cancer screenings and their screening intention, underscoring the need to take into account dimensions of health literacy beyond basic functional skills. Conclusions. From a public health perspective, findings provide further evidence on the importance of adapting informational and educational communication intervention designed to improve cancer prevention and screening to different audiences.

    Chemokines are key players of the cancer-related inflammation. Chemokine ligands and receptors are downstream of genetic events that cause neoplastic transformation and are abundantly expressed in chronic inflammatory conditions which predispose to cancer. Components of the chemokine system affect multiple pathways of tumor progression including: leukocyte recruitment, neo-angiogenesis, tumor cell proliferation and survival, invasion and metastasis. Evidence in pre-clinical and clinical settings suggests that the chemokine system represents a valuable target for the development of innovative therapeutic strategies.

    New and more effective treatments for cancer have resulted in individuals living longer with a better quality of life. Many more survivors are employed in the workplace. Cancer is no longer only an issue for survivors and their families; it has become an issue for the employer and the workplace. This article describes survey results of 4,364 long term cancer survivors in which they were asked to respond to items describing their ability to work, job discrimination, and quality of life. Thirty-five percent of survivors were working at the time they completed the survey, and 8.5% considered themselves unable to work. This research has shown that age, gender, ethnic group, and cancer type affected the working status of the survivors. Of survivors continuing to work, 7.3% indicated they had experienced job discrimination. The results indicate most cancer survivors do not perceive employment related problems, and are readily assimilated into the work force. Job discrimination and the ability to work is a quality of life issue.

    We propose a dynamical system of tumor cells proliferation based on operatorial methods. The approach we propose is quantum-like: we use ladder and number operators to describe healthy and tumor cells birth and death, and the evolution is ruled by a non-hermitian Hamiltonian which includes, in a non reversible way, the basic biological mechanisms we consider for the system. We show that this approach is rather efficient in describing some processes of the cells. We further add some medical treatment, described by adding a suitable term in the Hamiltonian, which controls and limits the growth of tumor cells, and we propose an optimal approach to stop, and reverse, this growth.

    The breast cancer screening (BCS) chart is suggested as a basic and preliminary tool to improve efficiency of screening mammography. We conducted this case-control study in 2016 and enrolled 1422 women aged 30-75 years, including 506 women with breast cancer (cases) and 916 women without breast cancer (controls). We developed the BCS chart using a multiple logistic regression analysis. We combined the risks of breast cancer to predict the individual risk of breast cancer. Then, we stratified and colored the predicted risk probabilities as follows: green), 05-09% (yellow), 10-14% (orange), 15-19% (red), 20-24% (brown) and ≥25% (black). The BCS chart provides the risk probability of breast cancer, based on age, body mass index, late menopause, having a benign breast disease and a positive family history of breast cancer among the first-degree or the second/third-degree relatives. According to this chart, an individual can be classified in a category of low risk (green), medium risk (yellow and orange), high risk (red and brown) and very high risk (black) for breast cancer. This chart is a flexible and easy to use tool that can detect high-risk subjects and make the screening program more efficient and productive. © The Author 2017.

    Brewer, Cynthia A

    2006-02-01

    Maps and other data graphics may play a role in generating ideas and hypotheses at the beginning of a project. They are useful as part of analyses for evaluating model results and then at the end of a project when researchers present their results and conclusions to varied audiences, such as their local research group, decision makers, or a concerned public. Cancer researchers are gaining skill with geographic information system (GIS) mapping as one of their many tools and are broadening the symbolization approaches they use for investigating and illustrating their data. A single map is one of many possible representations of the data, so making multiple maps is often part of a complete mapping effort. Symbol types, color choices, and data classing each affect the information revealed by a map and are best tailored to the specific characteristics of data. Related data can be examined in series with coordinated classing and can also be compared using multivariate symbols that build on the basic rules of symbol design. Informative legend wording and setting suitable map projections are also basic to skilled mapmaking.

    We determined the extent and distribution of cancers in relatives of 379 children newly diagnosed with cancer. Family history was collected from 1,337 first-degree and 3,399 second-degree relatives and incidence compared with national age- and gender-specific rates. Overall, 14 children (3.7%) had a relative with a history of childhood cancer and 26 children (6.9%) had a first-degree relative with a history of cancer, with only one of these having an identifiable familial cancer syndrome. There was a higher than expected incidence of childhood cancer among first-degree relatives (parents and siblings) (standardized incidence ratio (SIR) 1.43; 95% CI 0.54-5.08). There was also a higher than expected incidence of adult cancers among first-degree relatives (SIR 1.45; 95% CI 0.93-2.21), particularly in females (SIR 1.82; 95% CI 1.26-3.39). The increased family cancer history in first-degree females was largely attributable to an effect in mothers (SIR 1.78; 95% CI 1.27-3.33). The gender-specific association was reflected in higher than expected incidence rates of breast cancer in both mothers (SIR 1.92; 95% CI 0.72-6.83) and aunts (SIR 1.64; 95% CI 0.98-2.94). These findings support the hypothesis that previously undetected familial cancer syndromes contribute to childhood cancer.

    Full Text Available Prostate cancer is a global public health problem, and it is the most common cancer in American men and the second cause for cancer-related death. Experimental evidence shows that prostate tissue possesses cannabinoid receptors and their stimulation results in anti-androgenic effects. To review currently relevant findings related to effects of cannabinoid receptors in prostate cancer. PubMed search utilizing the terms "cannabis," "cannabinoids," "prostate cancer," and "cancer pain management," giving preference to most recent publications was done. Articles identified were screened for their relevance to the field of prostate cancer and interest to both urologist and pain specialists. Prostate cancer cells possess increased expression of both cannabinoid 1 and 2 receptors, and stimulation of these results in decrease in cell viability, increased apoptosis, and decreased androgen receptor expression and prostate-specific antigen excretion. It would be of interest to conduct clinical studies utilizing cannabinoids for patients with metastatic prostate cancer, taking advantage not only of its beneficial effects on prostate cancer but also of their analgesic properties for bone metastatic cancer pain.

  8. Role of endocrine-genotoxic switchings in cancer and other human diseases: basic triad.

    Berstein, Lev M

    2008-01-01

    Cancer is one of the leading causes of human death and belongs to the group of main chronic noncommunicable diseases (NCD). Certain specific features ofNCD have raised the concept of 'normal' and 'successful' aging. The apparent paradox of simultaneous increase with aging of the diseases connected with estrogen deficiency as well as with estrogenic excess can be explained by the existence of the phenomenon of the switching of estrogen effects. An isolated or combined with the weakening of hormonal effect increase in genotoxic action of estrogens can modify the course ofage-associated pathology. In particular, such changes in estrogen effect may alter the biology of tumors to make them less favorable/more aggressive. Two other endocrine-genotoxic switchings (EGS) involving phenomena ofJanus (dual) function of glucose and adipogenotoxicosis may produce similar influences on tumor and other NCD biology. These three phenomena form a'basic triad' and can act independently of each other or in concert. EGS and their inductors may serve as targets for prevention and, probably, treatment of main noncommunicable diseases. The measures to correct components of the 'triad' can be divided into several groups aimed to optimally orchestrate the balance between endocrine and DNA-damagingeffects of estrogens, glucose and adipose tissue-related factors.

    2015-03-01

    Relatives are the primary and existential resource of cancer patients, while at the same time experiencing substantial distress themselves. This article presents a description of tasks, roles and distress factors, the prevalence of psychosocial distress, description of risk factors in families contributing to dysfunctional coping, options and empirical evidence for the efficacy of psychosocial support. Evaluation of registry data, analysis of case reports, discussion of basic research findings, meta-analyses and expert judgments. Psychosocial distress in relatives of cancer patients is comparable to the degree of distress experienced by the patients and is sometimes even higher. Distress in relatives is still underrecognized, underreported and undertreated. Hostile interaction patterns, low emotional expression and high conflict tendencies impair coping with cancer and its treatment. Psychosocial support for the family of cancer patients improves coping behavior and the quality of life both in relatives and patients. Professional and lay caregivers need to adopt a social perspective on cancer whereby participation and inclusion of relatives in the treatment, acknowledgment of their engagement and recognition of their distress is beneficial for both patients and their relatives. Screening for psychosocial distress in relatives is recommended, attention should be drawn to psychosocial support services and utilization should be encouraged.

  10. Other cancers in lung cancer families are overwhelmingly smoking-related cancers

    2017-06-01

    Full Text Available Familial risks of lung cancer are well-established, but whether lung cancer clusters with other discordant cancers is less certain, particularly beyond smoking-related sites, which may provide evidence on genetic contributions to lung cancer aetiology. We used a novel approach to search for familial associations in the Swedish Family-Cancer Database. This involved assessment of familial relative risk for cancer X in families with increasing numbers of lung cancer patients and, conversely, relative risks for lung cancer in families with increasing numbers of patients with cancers X. However, we lacked information on smoking. The total number of lung cancers in the database was 125 563. We applied stringent statistical criteria and found that seven discordant cancers were associated with lung cancer among family members, and six of these were known to be connected with smoking: oesophageal, upper aerodigestive tract, liver, cervical, kidney and urinary bladder cancers. A further novel finding was that cancer of unknown primary also associated with lung cancer. We also factored in histological evidence and found that anal and connective tissue cancers could be associated with lung cancer for reasons other than smoking. For endometrial and prostate cancers, suggestive negative associations with lung cancer were found. Although we lacked information on smoking it is prudent to conclude that practically all observed discordant associations of lung cancer were with cancers for which smoking is a risk factor.

  11. Hereditary Nonpolyposis Colorectal Cancer and Cancer Syndromes: Recent Basic and Clinical Discoveries

    2018-01-01

    Full Text Available Approximately one-third of individuals diagnosed with colorectal cancer have a family history of cancer, suggesting that CRCs may result from a heritable component. Despite the availability of current gene-identification techniques, only 5% of all CRCs emerge from well-identifiable inherited causes for predisposition, including polyposis and nonpolyposis syndromes. Hereditary nonpolyposis colorectal cancer represents a large proportion of cases, and robustly affected patients are at increased risk for early onset, synchronous, and metachronous colorectal malignancies and extracolonic malignancies. HNPCC encompasses several cancer syndromes, such as Lynch syndrome, Lynch-like syndrome, and familial colorectal cancer type X, which have remarkable clinical presentations and overlapping genetic profiles that make clinical diagnosis a challenging task. Therefore, distinguishing between the HNPCC disorders is crucial for physicians as an approach to tailor different recommendations for patients and their at-risk family members according to the risks for colonic and extracolonic cancer associated with each syndrome. Identification of these potential patients through epidemiological characteristics and new genetic testing can estimate the individual risk, which informs appropriate cancer screening, surveillance, and/or treatment strategies. In the past three years, many appealing and important advances have been made in our understanding of the relationship between HNPCC and CRC-associated syndromes. The knowledge from the genetic profile of cancer syndromes and unique genotype-phenotype profiles in the different syndromes has changed our cognition. Therefore, this review presents and discusses HNPCC and several common nonpolyposis syndromes with respect to molecular phenotype, histopathologic features, and clinical presentation.

    The purpose of this project was to evaluate research in basic oral care interventions to update evidence-based practice guidelines for preventing and treating oral mucositis (OM) in cancer patients undergoing radio- or chemotherapy. A systematic review of available literature was conducted by the Basic Oral Care Section of the Mucositis Study Group of MASCC/ISOO. Seven interventions--oral care protocols, dental care, normal saline, sodium bicarbonate, mixed medication mouthwash, chlorhexidine, and calcium phosphate--were evaluated using the Hadorn (J Clin Epidemiol 49:749-754, 1996) criteria to determine level of evidence, followed by a guideline determination of one of the following: recommendation, suggestion, or no guideline possible, using Somerfield's (Classic Pap Cur Comments 4:881-886, 2000) schema. Fifty-two published papers were examined by treatment population (radiotherapy, chemotherapy, and hematopoietic stem cell transplant) and by whether the intervention aimed to prevent or treat OM. The resulting practice suggestions included using oral care protocols for preventing OM across all treatment modalities and age groups and not using chlorhexidine mouthwash for preventing OM in adults with head and neck cancer undergoing radiotherapy. Considering inadequate and/or conflicting evidence, no guidelines for prevention or treatment of OM were possible for the interventions of dental care, normal saline, sodium bicarbonate, mixed medication mouthwash, chlorhexidine in patients receiving chemotherapy or hematopoietic stem cell transplant, or calcium phosphate. The evidence for basic oral care interventions supports the use of oral care protocols in patient populations receiving radiation and/or chemotherapy and does not support chlorhexidine for prevention of mucositis in head and neck cancer patients receiving radiotherapy. Additional well-designed research is needed for other interventions to improve the amount and quality of evidence guiding future clinical

    Policy initiatives that aim to elevate the position of medical teaching to that of medical research could influence the satisfaction of three basic psychological needs related to motivation for medical teaching. To explore relations between the satisfaction of three basic psychological needs towards medical teaching and two policy initiatives for medical teaching: (Junior) Principal Lecturer positions [(J)PL positions] and Subsidized Innovation and Research Projects in Medical Education (SIRPMEs). An online questionnaire was used to collect data about medical teaching in the setting of a university hospital. We adapted the Work-related Basic Need Satisfaction scale (Van den Broeck et al. in J Occup Organ Psychol, 83(4):981-1002, 2010), in order to measure feelings of autonomy, competence, and relatedness in teaching. We examined the relations between (J)PL positions and SIRPMEs and the satisfaction of three basic psychological needs. A total of 767 medical teachers participated. The initiatives appear to be related to different beneficial outcomes in terms of feelings of autonomy, competence, and relatedness in medical teaching. Either a (J)PL position is obtained by teachers who feel competent and related towards medical teaching, or obtaining a (J)PL position makes teachers feel more competent and related towards teaching, or these relations could be interacting. Also, either a SIRPME is obtained by teachers who feel competent and autonomous towards medical teaching, or obtaining a SIRPME makes teachers feel more competent and autonomous towards teaching, or these relations could be interacting. Additional research needs to scrutinize the causal or interacting relations further and to determine optimal conditions for these policy initiatives more specifically. Implications for future research are discussed.

    Since nutrition can influence the process of carcinogenesis, this study's objectives are to review the relationship between nutrition and cancer from the point of view of the role of micronutrients in the treatment of cancer patients, and to get to know the deficit relationship and the excess of micronutrients, with the etiology and cancer treatment. At the same time the patient's weight loss relates, among other things, to the type of cancerous tumor, its location, stage thereof, reason for which it may be associated with the deficiency of macro and micronutrients as from psychogenic, anorectics and mal-absorption effects or with mechanical effects as obstruction, among other toxic effects that are common in the treatment of cancer. Hence, the importance that the nutrition expert must have in making an adequate overall nutritional evaluation that allows the nutritional diagnosis, in studying the dietary patterns, to determine the toxic effects of the antineoplastic treatment in order to handle the treatment's timing excellence, symptoms and signs, and thus act effectively optiimizing the patient's life quality, and therewith his/her survival. There are controversies as to which specific dietary factors are related to cancer etiology and the results of studies on metabolic factors, and therefore, the relationship Cancer-Nutrition is quiet complex.

  19. Urological cancer related to familial syndromes

    Directory of Open Access Journals (Sweden)

    Walter Henriques da Costa

    Full Text Available ABSTRACT Cancer related to hereditary syndromes corresponds to approximately 5-10% of all tumors. Among those from the genitourinary system, many tumors had been identified to be related to genetic syndromes in the last years with the advent of new molecular genetic tests. New entities were described or better characterized, especially in kidney cancer such as hereditary leiomyomatosis renal cell carcinoma (HLRCC, succinate dehydrogenase kidney cancer (SDH-RCC, and more recently BAP1 germline mutation related RCC. Among tumors from the bladder or renal pelvis, some studies had reinforced the role of germline mutations in mismatch repair (MMR genes, especially in young patients. In prostate adenocarcinoma, besides mutations in BRCA1 and BRCA2 genes that are known to increase the incidence of high-risk cancer in young patients, new studies have shown mutation in other gene such as HOXB13 and also polymorphisms in MYC, MSMB, KLK2 and KLK3 that can be related to hereditary prostate cancer. Finally, tumors from testis that showed an increased in 8 - 10-fold in siblings and 4 - 6-fold in sons of germ cell tumors (TGCT patients, have been related to alteration in X chromosome. Also genome wide association studies GWAS pointed new genes that can also be related to increase of this susceptibility.

  1. RELATIONS BETWEEN BASIC MOTOR ABILITIES AND SPECIFIC PRECISENESS OF FOOTBALLERS AGED 10-12

    Directory of Open Access Journals (Sweden)

    Miroslav Smajić

    2007-05-01

    Full Text Available According to the research on the sample of 256 footballers aged 10-12 and the battery including 20 tests for evaluation of the basic motor abilities and the battery of 24 tests for evaluation of specifi c preciseness, and as per canonic-correlation analysis, a general conclusion can be reached that the boys were rather different in their basic motor abilities. The differences were especially high in explosive strength, coordination, aerobic endurance and balance. One could also conclude that the sample treated in this manner (10-12 years of age is very heterogeneous with respect to basic motor abilities. The subjects showed the highest homogeneity in the tests of specifi c preciseness. They also achieved particularly good results in the tests of vertical target hitting by leg and head. Considering the relations of the basic motor abilities and specifi c preciseness, it was concluded that the structure-based basic motor-canonic factor might be interpreted as FACTOR OF SPEED ENDURANCE AND EXPLOSIVE STRENGTH, whereas structurebased canonic factor of specifi c preciseness might be interpreted as the FACTOR OF SPECIFIC PRECISENESS OF VERTICAL TARGET HITTING BY LEG AND HEAD. The structure of the relations of the fi rst pair of canonic factors indicates that footballers with lower speed endurance and lower explosive strength achieved poorer results in the tests of specifi c preciseness of vertical target hitting by leg and head, and vice versa. Structure of the relations of the second canonic factor indicates quite clearly that the footballers with lower repetitive strength achieved lower results in the tests of specifi c preciseness of horizontal and vertical target by leg and head in a newly created situation. Here of course, the opposite was true, i.e. footballers with higher repetitive strength were better in these tests too.

    Time can be observed as a subjective, as well as an objective phenomenon which is a component of our life, and due to its communicational needs, it is standardized by temporal signs and symbols. The aim of this study was to determine the understanding of basic temporal relations of pupils with hearing impairments. We assumed that the knowledge of basic time relations is a precondition for the acquisition of knowledge that is connected with the understanding of the syllabus in regular school programs. Three groups of pupils have been examined: pupils with hearing impairments who attend the primary school of SUVAG Polyclinic under special condition, integrated hearing impaired pupils with minor additional difficulties who attend regular primary schools in Zagreb with a prolonged expert procedure and pupils of the control group. The subjects have been examined with a measuring instrument constructed by the expert team of the Polyclinic Suvag. Twenty nine subjects have been questioned, chronologically aged between 10 and 12.

  3. Human Induced Pluripotent Stem Cells from Basic Research to Potential Clinical Applications in Cancer

    Directory of Open Access Journals (Sweden)

    Teresa de Souza Fernandez

    2013-01-01

    Full Text Available The human induced pluripotent stem cells (hiPSCs are derived from a direct reprogramming of human somatic cells to a pluripotent stage through ectopic expression of specific transcription factors. These cells have two important properties, which are the self-renewal capacity and the ability to differentiate into any cell type of the human body. So, the discovery of hiPSCs opens new opportunities in biomedical sciences, since these cells may be useful for understanding the mechanisms of diseases in the production of new diseases models, in drug development/drug toxicity tests, gene therapies, and cell replacement therapies. However, the hiPSCs technology has limitations including the potential for the development of genetic and epigenetic abnormalities leading to tumorigenicity. Nowadays, basic research in the hiPSCs field has made progress in the application of new strategies with the aim to enable an efficient production of high-quality of hiPSCs for safety and efficacy, necessary to the future application for clinical practice. In this review, we show the recent advances in hiPSCs’ basic research and some potential clinical applications focusing on cancer. We also present the importance of the use of statistical methods to evaluate the possible validation for the hiPSCs for future therapeutic use toward personalized cell therapies.

    Natural killer (NK) cells, which recognize and kill target cells independent of antigen specificity and major histocompatibility complex (MHC) matching, play pivotal roles in immune defence against tumors. However, tumor cells often acquire the ability to escape NK cell-mediated immune surveillance. Thus, understanding mechanisms underlying regulation of NK cell phenotype and function within the tumor environment is instrumental for designing new approaches to improve the current cell-based immunotherapy. In this review, we elaborate the main biological features and molecular mechanisms of NK cells that pertain to regulation of NK cell-mediated anti-tumor activity. We further overview current clinical approaches regarding NK cell-based cancer therapy, including cytokine infusion, adoptive transfer of autologous or allogeneic NK cells, applications of chimeric antigen receptor (CAR)-expressing NK cells and adoptive transfer of memory-like NK cells. With these promising clinical outcomes and fuller understanding the basic questions raised in this review, we foresee that NK cell-based approaches may hold great potential for future cancer immunotherapy.

    2017-01-01

    Full Text Available Cancer stem cells (CSCs, with their self-renewal ability and multilineage differentiation potential, are a critical subpopulation of tumor cells that can drive tumor initiation, growth, and resistance to therapy. Like embryonic and adult stem cells, CSCs express markers that are not expressed in normal somatic cells and are thus thought to contribute toward a “stemness” phenotype. This review summarizes the current knowledge of stemness-related markers in human cancers, with a particular focus on important transcription factors, protein surface markers, and signaling pathways.

Much of the previous research on social media and health communication has focused on Facebook groups related to a specific disease or Facebook pages related to an advocacy organization. Less is known about how people communicate about cancer on personal Facebook pages. In this study, we expand upon previous research by examining how cancer caregivers use personal Facebook pages for cancer-related communication. We examined themes in cancer-related exchanges through a content analysis of 12 months of data from 18 publically available Facebook pages hosted by parents of children with acute lymphoblastic leukemia (15 852 total posts). Six themes emerged: (1) documenting the cancer journey, (2) sharing emotional strain associated with caregiving, (3) promoting awareness and advocacy about pediatric cancer, (4) fundraising, (5) mobilizing support, and (6) expressing gratitude for support. Building upon previous research documenting the increasing use of social media for health-related communication and support, our findings show that personal Facebook pages offer a platform for cancer caregivers to share their cancer-related experiences, promote advocacy and awareness, and mobilize social support. Providers must recognize the importance of social media as a vehicle for support and communication for families of children with cancer. Nurses should educate parents on how to appraise information obtained through Facebook using evidence-based guidelines. Providers can encourage caregivers to use Facebook as a tool for communication, information, and support.

    2017-05-01

    Full Text Available Introduction: Taste change due to cancer is a notorious side effect, adversely affecting appetite and weight. Even though taste change or dysgeusia is one of the major causes of poor nutritional status in cancer survivors, it is not addressed as a significant problem and is often left untreated. The main purpose of this review is to explore current knowledge of pharmacological and behavioral interventions for the treatment of cancer related taste change. Methods: This systematic review was conducted in accordance with PRISMA guidelines to identify original articles on taste change. Multiple databases including; Scopus, Medline, EMBASE, CINAHL, and all databases via Pro quest were searched for original articles or studies related to taste change caused by cancer or its treatment. Relevant articles were subjected to a full text evaluation and assessed by Critical appraisal skills program (CASP guidelines and the Effective public health practice project (EPHPP instrument. Results: The search revealed 12 eligible studies, six of which were randomized controlled trials. Most of the studies used a standardized validated tool to measure taste change. Dysgeusia is common in cancer, 14 to 100% cancer patient report it. Pharmacological management with zinc remains inconclusive as one study reports it as beneficial and two other studies reported null effect. Few studies suggested dietary modifications such as use of sugary, salty foods that are helpful to reduce the effect of dysgeusia. Conclusion: Dietary counseling and informing the patient well about self-care strategies before treatment has consistently shown positive results on taste change, with strong statistical power. Other potential treatments for dysgeusia such as zinc, amifostine, and megestrol acetate gave inconsistent results.

    The author has developed dynamic sequential computed tomography with table incrementation during arterial portography (DSCTI-AP) for the precise diagnosis of liver cancers. 1. Basic Studies on DSCTI-AP; 1) The phantom experiment simulating DSCTI-AP revealed that it is possible to resolve a cylindrical object 5 mm in diameter with more than 50 Hounsfield Unit (HU) difference in the attenuation value compared to the surrounding area by third generation CT scanner. 2) All macroscopically visible nodules of hepatocellular carcinoma (HCC) chemically induced in rat liver and VX2 tumor transplanted via the portal vein in rabbit liver were visualized as portal perfusion defects on portal microangiograms and nodular low density areas in CT during portography. 2. Analysis of the clinical usefulness of DSCTI-AP; 1) The smallest nodules of HCC and metastatic liver cancer detected by DSCTI-AP were 5 mm in diameter. 2) DSCTI-AP was superior to radionuclide liver scanning, ultrasound (US), computed tomography (CT), selective celiac arteriography (SCA) and infusion hepatic angiography (IHA) in the detection of small HCC. But IHA was superior to DSCTI-AP in visualizing extremely hypervascular HCC nodules, and all of the small HCCs were demonstrated by the combination of DSCTI-AP and IHA. 3) DSCTI-AP was superior to the all other imaging modalities including CT following intraarterial injection of iodized oil (Lipiodol CT) in detecting metastatic liver cancers especially less than 1 cm in diameter. 4) Lipiodol CT was superior to DSCTI-AP in visualizing small hypervascular HCC nodules. 5) DSCTI-AP was the most sensitive method in diagnosing peripheral intrahepatic portal tumor thrombus. 6) DSCTI-AP had the advantage in visualizing the location of hepatic tumors and their relation to major vessels objectively.

    Background: Health-related Habits (HrH) are a major priority in healthcare. However there is little agreement on whether exercise, diet, smoking or dental hygiene are better described as lifestyles, habits or behaviors, and on what is their hierarchical relationship. This research is aimed at representing the basic concepts which are assumed to constitute the conceptual framework enabling us to interpret and organize the field of HrH. Methods: A group of 29 experts with different backgrounds agreed on the definition and hierarchy of HrH following an iterative process which involved framing analysis and nominal group techniques. Results: Formal definitions of health-related behavior, habit, life-style and life-style profile were produced. In addition a series of basic descriptors were identified: health reserve, capital, risk and load. Six main categories of HrH were chosen based on relevance to longevity: diet/exercise, vitality/stress, sleep, cognition, substance use and other risk. Attributes of HrH are clinical meaningfulness, quantifiability, temporal stability, associated morbidity, and unitarity (non-redundancy). Two qualifiers (polarity and stages of change) have also been described. Conclusions: The concepts represented here lay the groundwork for the development of clinical and policy tools related to HrH and lifestyle. An adaptation of this system to define targets of health interventions and to develop the classification of person factors in ICF may be needed in the future. PMID:23670578

    Full Text Available Numerical integration of the airplane’s equations of motion has long been considered among the most fundamental calculations in airplane’s analysis. Numerical algorithms have been implemented and experimentally validated. However, the need for superior speed and accuracy is still very topical, as, nowadays, various optimization algorithms rely heavily on data generated from the integration of the equations of motion and having access to larger amounts of data can increase the quality of the optimization. Now, for a number of decades, engineers have relied heavily on commercial codes based on automatically selected integration steps. However, optimally chosen constant integration steps can save time and allows for larger numbers of integrations to be performed. Yet, the basic papers that presented the fundamentals of numerical integration, as applied to airplane’s equations of motion are nowadays not easy to locate. Consequently, this paper presents a review of basic aspects related to the integration of airplane’s equation of motion. The discussion covers fundamentals of longitudinal and lateral-directional motion as well as the implementation of some numerical integration methods. The relation between numerical integration steps, accuracy, computational resource usage, numerical stability and their relation with the parameters describing the dynamic response of the airplane is considered and suggestions are presented for a faster yet accurate numerical integration.

    Full Text Available Abstract Background Attention-Deficit/Hyperactivity Disorder (ADHD is a prevalent, complex disorder which is characterized by symptoms of inattention, hyperactivity, and impulsivity. Convergent evidence from neurobiological studies of ADHD identifies dysfunction in fronto-striatal-cerebellar circuitry as the source of behavioural deficits. Recent studies have shown that regions governing basic sensory processing, such as the somatosensory cortex, show abnormalities in those with ADHD suggesting that these processes may also be compromised. Methods We used event-related magnetoencephalography (MEG to examine patterns of cortical rhythms in the primary (SI and secondary (SII somatosensory cortices in response to median nerve stimulation, in 9 adults with ADHD and 10 healthy controls. Stimuli were brief (0.2 ms non-painful electrical pulses presented to the median nerve in two counterbalanced conditions: unpredictable and predictable stimulus presentation. We measured changes in strength, synchronicity, and frequency of cortical rhythms. Results Healthy comparison group showed strong event-related desynchrony and synchrony in SI and SII. By contrast, those with ADHD showed significantly weaker event-related desynchrony and event-related synchrony in the alpha (8–12 Hz and beta (15–30 Hz bands, respectively. This was most striking during random presentation of median nerve stimulation. Adults with ADHD showed significantly shorter duration of beta rebound in both SI and SII except for when the onset of the stimulus event could be predicted. In this case, the rhythmicity of SI (but not SII in the ADHD group did not differ from that of controls. Conclusion Our findings suggest that somatosensory processing is altered in individuals with ADHD. MEG constitutes a promising approach to profiling patterns of neural activity during the processing of sensory input (e.g., detection of a tactile stimulus, stimulus predictability and facilitating our

  17. Unmodifiable variables related to thyroid cancer incidence

    2018-04-01

    Full Text Available The incidence of thyroid cancer is significantly different between male and female patients. Thyroid cancer is also the only form of cancer where age can be considered a staging variable. Identifying biological prognostic factors such as age or sex is important as it helps select an optimal personalized therapy. The present analysis is an observational, prospective study that enrolled all patients with thyroid disease who were operated upon at a single center. The study aimed to determine the most frequent age at presentation, the predominance of one sex over the other, the incidence of malignant thyroid disease, and the relative risk for each sex to develop thyroid carcinoma. The incidence of thyroid carcinoma was higher for women than for men, with a higher relative risk in the female subgroup. Incidence was also highest in the 50-60-year-old group. Given that studies show better survival for women and for younger patients, even when presenting with advanced disease, compared with older, male patients, such prognostic indicators should be a factor in the treatment decision.

    2014-01-01

    This article gives an overview of the established radionuclide therapies for endocrine-related cancer that already have market authorization or are currently under evaluation in clinical trials. Radioiodine therapy is still the gold standard for differentiated iodine-avid thyroid cancer. In patients with bone and lung metastases (near) total remission is seen in approximately 50 % and the 15-year survival rate for these patients is approximately 90 %. In contrast to the USA, meta-iodobenzylguanidine (MIBG) therapy has market approval in Europe. According to the current literature, in the setting of advanced stage neuroblastoma and malignant pheochromocytoma or paraganglioma, radiological remission can be achieved in > 30 % and symptom control in almost 80 % of the treated patients. Somatostatin receptor targeted radionuclide therapies (e.g. with DOTATATE or DOTATOC) demonstrated promising results in phase 2 trials, reporting progression-free survival in the range of 24-36 months. A first phase 3 pivotal trial for intestinal carcinoids is currently recruiting and another trial for pancreatic neuroendocrine tumors is planned. Radiopharmaceuticals based on glucagon-like peptide 1 (GLP1) or minigastrins are in the early evaluation stage for application in the treatment of insulinomas and medullary thyroid cancer. In general, radiopharmaceutical therapy belongs to the group of so-called theranostics which means that therapy is tailored for individual patients based on molecular imaging diagnostics to stratify target positive or target negative tumor phenotypes.

    Full Text Available Abstract Background More so than the traditional socioeconomic indicators, such as education and income, wealth reflects the accumulation of resources and makes socioeconomic ranking manifest and explicitly visible to the outside world. While the lack of basic goods, such as a refrigerator, may affect health directly, via biological pathways, the lack of luxury goods, such as an LCD television, may affect health indirectly through psychosocial mechanisms. We set out to examine, firstly, the relevance of both basic and luxury goods in explaining health-related dysfunction in older persons, and, secondly, the extent to which these associations are independent of traditional socioeconomic indicators. Methods Cross-sectional and longitudinal data from 2067 men and women aged 55 years and older who participated in the Study on Medical Information and Lifestyles Eindhoven (SMILE were gathered. Logistic regression analyses were used to study the relation between a lack of basic and luxury goods and health-related function, assessed with two sub-domains of the SF-36. Results The lack of basic goods was closely related to incident physical (OR = 2.32 and mental (OR = 2.12 dysfunction, even when the traditional measures of socioeconomic status, i.e. education or income, were taken into account. Cross-sectional analyses, in which basic and luxury goods were compared, showed that the lack of basic goods was strongly associated with mental dysfunction.

    Full Text Available This short letter manifests how Smarandache geometries can be employed in order to extend the “classical” basis of the General Theory of Relativity (Riemannian geometry through joining the properties of two or more (different geometries in the same single space. Perspectives in this way seem much profitable: the basic space-time of General Relativity can be extended to not only metric geometries, but even to non-metric ones (where no distances can be measured, or to spaces of the mixed kind which possess the properties of both metric and non-metric spaces (the latter should be referred to as “semi-metric spaces”. If both metric and non-metric properties possessed at the same (at least one point of a space, it is one of Smarandache geometries, and should be re- ferred to as “Smarandache semi-metric space”. Such spaces can be introduced accord- ing to the mathematical apparatus of physically observable quantities (chronometric invariants, if we consider a breaking of the observable space metric in the continuous background of the fundamental metric tensor.

    Through the success of basic and disease-specific research, cancer survivors are one of the largest growing subsets of individuals accessing the healthcare system. Interestingly, cardiovascular disease is the second leading cause of morbidity and mortality in cancer survivors after recurrent malignancy. This recognition has helped stimulate a collaboration between oncology and cardiology practitioners and researchers, and the portmanteau cardio-oncology (also known as onco-cardiology) can now be found in many medical centers. This collaboration promises new insights into how cancer therapies impact cardiovascular homeostasis and long-term effects on cancer survivors. In this review, we will discuss the most recent views on the cardiotoxicity related to various classes of chemotherapy agents and radiation. We will also discuss broadly the current strategies for treating and preventing cardiovascular effects of cancer therapy. © 2016 American Heart Association, Inc.

    Studies have reported higher levels of absenteeism due to illness among special education teachers compared to other teachers, but it is not known which factors might contribute to this difference. We examined whether health, health behaviors, and exposure to violence at work differed between special education and general education teachers in Finnish basic education. Survey data from 5760 general and special education teachers were analyzed with multilevel logistic models adjusted for individual- and school-level confounding factors. No difference was found between the health behaviors of general and special education teachers. The differences in physical and mental health between the two groups were also relatively small. With regard to work-related violence, however, male special education teachers were 3 times more likely to be exposed to mental abuse, and 5 times more likely to be exposed to physical violence when compared to their male colleagues in general education. Although female special educators were also at an increased risk of mental abuse and physical violence compared to their female general teacher colleagues, their odds ratios for such an encounter were smaller (2- and 3-fold, respectively) than those of male special education teachers. The school-level variance of physical violence toward teachers was large, which indicates that while most schools have little physical violence toward teachers, schools do exist in which teachers' exposure to violence is common. These findings suggest that special education teachers may benefit from training for handling violent situations and interventions to prevent violence at schools. © 2012, American School Health Association.

  8. Basic principles in approaching patient and his family in the terminal phase of cancer

    2016-01-01

    Serious life threatening disease including cancer appears to be not exclusively a medical problem. The stepwise treatment failure opens up a dilemma for patient and physician on how to cope with the new situation. Especially, disclosure of the reality by health care providers with an emphatic feeling is coupled with emotional pressure that is for many caregivers difficult to accept. The decision around the termination of curative treatment and the transition to palliative care is the most stressful event in the relation of caregivers to the the patient and his family. The patient being in the terminal phase of his disease is suffering from deep psychosocial crisis and the doctor patient communication remains the only possibility of helping patient to accept the reality of approaching death. The disclosure of „bad news“ is a stressful moment for caregivers themselves, that, besides of empathy, deserve communication skills and theoretical and professional preparedness. The aim of this paper is to open up a discussion about the most stressful life phase – dying and death – in the context of biomedical and psychosocial care of patients with serious life threatening disease.

    Compensation for asbestos-related cancers occurring in occupationally-exposed workers is a global issue; this is also an issue in Korea. To provide basic information regarding compensation for workers exposed to asbestos, 60 cases of asbestos-related occupational lung cancer and mesothelioma that were compensated during 15 yr; from 1993 (the year the first case was compensated) to 2007 by the Korea Labor Welfare Corporation (KLWC) are described. The characteristics of the cases were analyzed using the KLWC electronic data and the epidemiologic investigation data conducted by the Occupational Safety and Health Research Institute (OSHRI) of the Korea Occupational Safety and Health Agency (KOSHA). The KLWC approved compensation for 41 cases of lung cancer and 19 cases of mesothelioma. Males accounted for 91.7% (55 cases) of the approved cases. The most common age group was 50-59 yr (45.0%). The mean duration of asbestos exposure for lung cancer and mesothelioma cases was 19.2 and 16.0 yr, respectively. The mean latency period for lung cancer and mesothelioma cases was 22.1 and 22.6 yr, respectively. The major industries associated with mesothelioma cases were shipbuilding and maintenance (4 cases) and manufacture of asbestos textiles (3 cases). The major industries associated with lung cancer cases were shipbuilding and maintenance (7 cases), construction (6 cases), and manufacture of basic metals (4 cases). The statistics pertaining to asbestos-related occupational cancers in Korea differ from other developed countries in that more cases of mesothelioma were compensated than lung cancer cases. Also, the mean latency period for disease onset was shorter than reported by existing epidemiologic studies; this discrepancy may be related to the short history of occupational asbestos use in Korea. Considering the current Korean use of asbestos, the number of compensated cases in Korea is expected to increase in the future but not as much as developed countries.

    The aim of this study was to evaluate the levels of knowledge of pre-school teachers working in the province center of Isparta related with basic first-aid practices and some factors which affected these levels of knowledge. In this cross-sectional, analytic study, 110 pre-school teachers working in the province center of Isparta constituted the population. A questionnaire questioning sociodemographic properties and the level of knowledge related with first-aid practices was applied under supervision. The level of knowledge was evaluated on a 20-point scale. In the analyses, Kruskal-Wallis and Mann-Whitney U tests and Spearman's rank correlation were used. The study was approved by the Ethical Committee for Clinical Studies of Süleyman Demirel University School of Medicine (registration number: 105). The mean score of first-aid knowledge of the pre-school teachers was found to be 11.9±2.9. The least known issues included washing the wound by soap and water after a dog bite, information related with the necessity of immobilization of a child who has fallen from a high level and the phone number of National Poison Information Center (16.4%, 20.9% and 22.7%, respectively). The scores of the subjects whose knowledge of first-aid was evaluated to be well were higher compared to the subjects whose knowledge of first-aid was evaluated to be moderate (p=0.009) and poor (p=0.001). It was found that first-aid scores did not show significant difference in terms of age, working period, having received first-aid training and having faced with a condition requiring first-aid previously (p>0.05, for all comparisons). It was found that pre-school teachers had insufficient first-aid knowledge. Since the first-aid knowledge scores of the subjects who reported that they received first-aid training before did not show significant difference, it was thought that the quality of training was as important as receiving training.

    Palliative care in Indonesia is problematic because of cultural and socio-economic factors. Family in Indonesia is an integral part of caregiving process in inpatient and outpatient settings. However, most families are not adequately prepared to deliver basic care for their sick family member. This research is a pilot project aiming to evaluate how basic skills training (BST) given to family caregivers could enhance the quality of life (QoL) of palliative care cancer patients in Indonesia. The study is a prospective quantitative with pre and post-test design. Thirty family caregivers of cancer patients were trained in basic skills including showering, washing hair, assisting for fecal and urinary elimination and oral care, as well as feeding at bedside. Patients' QoL were measured at baseline and 4 weeks after training using EORTC QLQ C30. Hypothesis testing was done using related samples Wilcoxon Signed Rank. A paired t-test and one-way ANOVA were used to check in which subgroups was the intervention more significant. The intervention showed a significant change in patients' global health status/QoL, emotional and social functioning, pain, fatigue, dyspnea, insomnia, appetite loss, constipation and financial hardship of the patients. Male patient's had a significant effect on global health status (qol) (p = 0.030); female patients had a significant effect on dyspnea (p = 0.050) and constipation (p = 0.038). Younger patients had a significant effect in global health status/QoL (p = 0.002). Patients between 45 and 54 years old had significant effect on financial issue (p = 0.039). Caregivers between 45 and 54 years old had significant effect on patients' dyspnea (p = 0.031). Basic skills training for family caregivers provided some changes in some aspects of QoL of palliative cancer patients. The intervention showed promises in maintaining the QoL of cancer patients considering socio-economic and cultural challenges in the provision of

    Recently, the low invasive cancer treatments with small aftereffects have been considered. We are studying on the suppression methods of cancer cell proliferation with ultrasound. Cancer cells of mouse T lymphoma (EL-4) have been used in our study. The human histitocytic lymphoma cells (U-937) was used in this time. The cancer cells were cultured in a culture medium of RPMI1640. The standing wave acoustic field was formed in a water tank of our ultrasound exposure system by a vibrating plate driven with a Langevine type transducer. The U-937 and EL-4 were exposed to ultrasound in the acoustic field with spatial average acoustic intensity of 350 mW/cm(2) at 150 kHz. The viable rate of EL-4 decreased with the lapse of culture time after ultrasound exposure. U-937 did not show the remarkable decrease tendency. The proliferation of U-937 which exposed to ultrasound with 700 mW/cm(2) was suppressed. It can be thought that apoptosis was induced in the cancer cells in this condition. We observed the morphological change on the U-937 exposed to ultrasound with this condition. The morphological changes by apoptosis like the shrink of cells, formation of apoptotic bodies etc. can be observed with an optical microscope and a phase contrast microscope.

    Familial aggregation of testicular cancer has been reported consistently, but it is less clear if there is any association between risk of testicular cancer and other cancers in the family. We conducted a population based case-control study to examine the relationship between risk of testicular cancer and 22 different cancers in first-degree relatives. We included 3297 cases of testicular cancer notified to the Danish Cancer Registry between 1991 and 2003. 6594 matched controls were selected from the Danish Civil Registration System, which also provided the identity of 40,104 first-degree relatives of case and controls. Familial cancer was identified by linkage to the Danish Cancer Registry, and we used conditional logistic regression to analyse whether cancer among first-degree relatives was associated with higher risk of testicular cancer. Rate ratio (RR) for testicular cancer was 4.63 (95% CI: 2.41–8.87) when a father, 8.30(95% CI: 3.81–18.10) when a brother and 5.23 (95% CI: 1.35–20.26) when a son had testicular cancer compared with no familial testicular cancer. Results were similar when analyses were stratified by histologic subtypes of testicular cancer. Familial Non-Hodgkin lymphoma and oesophageal cancer were associated with testicular cancer; however these may be chance findings. The familial aggregation of testicular and possibly other cancers may be explained by shared genes and/or shared environmental factors, but the mutual importance of each of these is difficult to determine.

    2015-01-01

    Fatigue is one of the most common and distressing side effects of cancer and its treatment, and may persist for years after treatment completion in otherwise healthy survivors. Cancer-related fatigue causes disruption in all aspects of quality of life and may be a risk factor for reduced survival. The prevalence and course of fatigue in cancer patients has been well characterized, and there is growing understanding of underlying biological mechanisms. Inflammation has emerged as a key biological pathway for cancer-related fatigue, with studies documenting links between markers of inflammation and fatigue before, during, and particularly after treatment. There is considerable variability in the experience of cancer-related fatigue that is not explained by disease- or treatment-related characteristics, suggesting that host factors may play an important role in the development and persistence of this symptom. Indeed, longitudinal studies have begun to identify genetic, biological, psychosocial, and behavioral risk factors for cancer-related fatigue. Given the multi-factorial nature of cancer-related fatigue, a variety of intervention approaches have been examined in randomized controlled trials, including physical activity, psychosocial, mind-body, and pharmacological treatments. Although there is currently no gold standard for treating fatigue, several of these approaches have shown beneficial effects and can be recommended to patients. This report provides a state of the science review of mechanisms, risk factors, and interventions for cancer-related fatigue, with a focus on recent longitudinal studies and randomized trials that have targeted fatigued patients.

    Full Text Available Anthropometry is a science of human body measurement that could be used for manufacturing artificial limbs or prosthesis, investigating body differences between populations, utilizing in forensics and criminology, or even in the diagnosis of some diseases. Two of the most important anthropometric characteristics are dermatoglyphic patterns and finger length. Many studies have evaluated the relation between these two characteristics in different diseases such as cancers. It assumed that dermatoglyphic patterns and finger length could be used as predictors of some cancers such as gastric, ovarian, prostate, testicular, and breast cancers. In this review, we evaluated the relation between dermatoglyphic variability and finger length in different cancers more precisely.

    In recent years, cancer case counts in the U.S. underwent a large, rapid decline-an unexpected change given population growth for older persons at highest cancer risk. As these declines coincided with the Great Recession, we examined whether they were related to economic conditions. Using California Cancer Registry data from California's 30 most populous counties, we analyzed trends in cancer incidence during pre-recession (1996-2007) and recession/recovery (2008-2012) periods for all cancers combined and the ten most common sites. We evaluated the recession's association with rates using a multifactorial index that measured recession impact, and modeled associations between case counts and county-level unemployment rates using Poisson regression. Yearly cancer incidence rate declines were greater during the recession/recovery (3.3% among males, 1.4% among females) than before (0.7 and 0.5%, respectively), particularly for prostate, lung, and colorectal cancers. Lower case counts, especially for prostate and liver cancer among males and breast cancer, melanoma, and ovarian cancer among females, were associated with higher unemployment rates, irrespective of time period, but independent of secular effects. The associations for melanoma translated up to a 3.6% decrease in cases with each 1% increase in unemployment. Incidence declines were not greater in counties with higher recession impact index. Although recent declines in incidence of certain cancers are not differentially impacted by economic conditions related to the Great Recession relative to pre-recession conditions, the large recent absolute declines in the case counts of some cancer may be attributable to the large declines in unemployment in the recessionary period. This may occur through decreased engagement in preventive health behaviors, particularly for clinically less urgent cancers. Continued monitoring of trends is important to detect any rises in incidence rates as deferred diagnoses come to

    To study the relevance between cancer related fatigue and coping styles in breast cancer patients after chemotherapy. A survey was conducted in 396 patients with breast cancer after chemotherapy on cancer related fatigue scale and Jalowiec coping scale, and the relation was analyzed. The rate of overall fatigue in breast cancer patients was 96.97%, mostly moderate fatigue. The rate of fatigue dimensions from high to low was physical fatigue, feeling fatigue and cognitive fatigue, respectively. The score of coping styles in patients with breast cancer after chemotherapy from high to low was optimistic coping, facing bravely, support seeking, self-reliance, emotional catharsis, avoidance, fatalism, and conservation. The most widely used coping style was optimistic coping style, and the least was emotional catharisis. There was a positive correlation between coping style of emotional catharsis and cancer related fatigue of all dimensions (Pself-reliance, or conservation (P<0.05). There was also a negative correlation between physical fatigue and optimistic or support seeking (P<0.05), but there was a positive correlation between avoidance or fatalism and the dimensions of general fatigue, physical fatigue, and cognitive fatigue (P<0.05). There is prevalent cancer related fatigue in patients with breast cancer after chemotherapy. We should guide the patients to more active coping styles, to enhance the ability of psychological adaption in patients, reduce cancer related fatigue, and improve the quality of life.

    Full Text Available The objectives of this study were to investigate basic and drying properties of three wood species from Indonesia, i.e. kuda (Lannea coromandelica Merr., waru (Hibiscus tiliaceus L. and mindi besar (Melia dubia Cav.. The basic properties include density, shrinkages, modulus of rupture (MOR, compression parallel to grain (C//, wood strength and anatomical structures. Meanwhile, the drying properties included drying time and drying defects. The initial-final temperature and humidity for each species was based on defects that resulted from high temperature drying trial. The results showed that the drying properties were significantly affected by wood anatomical structure. The initial-final drybulb temperature and wetbulb depression   for kuda wood are 50 -70ºC and 3-30ºC respectively, while the corresponding figures for waru wood are 65-80ºC and 6-30ºC, and for mindi besar wood are 55-80ºC and 4-30ºC. These drying schedules, however, still need further trial prior to their implementation in the factory-scale operation. All wood species studied have density and considerable strength recommended in their use for light medium construction purposes. Mindi besar wood has decorative appearance so it is suitable for furniture.

    Basic research, exploring the hypothesis that 2-(ω-carboxyethyl)pyrrole (CEP) modifications of proteins are generated nonenzymatically in vivo is delivering a bonanza of molecular mechanistic insights into age-related macular degeneration, autism, cancer, and wound healing. CEPs are produced through covalent modification of protein lysyl ε-amino groups by γ-hydroxyalkenal phospholipids that are formed by oxidative cleavage of docosahexaenate-containing phospholipids. Chemical synthesis of CEP-modified proteins and the production of highly specific antibodies that recognize them preceded and facilitated their detection in vivo and enabled exploration of their biological occurrence and activities. This investigational approach –from the chemistry of biomolecules to disease phenotype – is proving to be remarkably productive. PMID:21875030

    When individuals stop working due to cancer this represents a loss to society - the loss of productivity. The aim of this analysis was to estimate productivity losses associated with premature mortality from all adult cancers and from the 20 highest mortality adult cancers in Ireland in 2011, and project these losses until 2030. An incidence-based method was used to estimate the cost of cancer deaths between 2011 and 2030 using the Human Capital Approach. National data were used for cancer, population and economic inputs. Both paid work and unpaid household activities were included. Sensitivity analyses estimated the impact of assumptions around future cancer mortality rates, retirement ages, value of unpaid work, wage growth and discounting. The 233,000 projected deaths from all invasive cancers in Ireland between 2011 and 2030 will result in lost productivity valued at €73 billion; €13 billion in paid work and €60 billion in household activities. These losses represent approximately 1.4 % of Ireland's GDP annually. The most costly cancers are lung (€14.4 billion), colorectal and breast cancer (€8.3 billion each). However, when viewed as productivity losses per cancer death, testis (€364,000 per death), cervix (€155,000 per death) and brain cancer (€136,000 per death) are most costly because they affect working age individuals. An annual 1 % reduction in mortality reduces productivity losses due to all invasive cancers by €8.5 billion over 20 years. Society incurs substantial losses in productivity as a result of cancer-related mortality, particularly when household production is included. These estimates provide valuable evidence to inform resource allocation decisions in cancer prevention and control.

    The phenomenon of aging has gained widespread attention in recent times. Although significant advances have been made to better understand aging and its related pathologies including cancer, there is not yet a clear mechanism explaining why diseases and cancer are inherent parts of the aging process. Finding a unifying equation that could bridge aging and its related diseases would allow therapeutic development and solve an immense human health problem to live longer and better. In this review, we discuss NAD + reduction as the central mechanism that may connect aging to its related pathologies and cancer. NAD + boosters would ensure and ameliorate health quality during aging. Copyright © 2017 Elsevier Inc. All rights reserved.

    2012-01-01

    Most brain gene expression studies of schizophrenia have been conducted in the frontal cortex or hippocampus. The extent to which alterations occur in other cortical regions is not well established. We investigated primary visual cortex (Brodmann area 17) from the Stanley Neuropathology Consortium collection of tissue from 60 subjects with schizophrenia, bipolar disorder, major depression, or controls. We first carried out a preliminary array screen of pooled RNA, and then used RT-PCR to quantify five mRNAs which the array identified as differentially expressed in schizophrenia (myelin basic protein [MBP], myelin-oligodendrocyte glycoprotein [MOG], β-actin [ACTB], thymosin β-10 [TB10], and superior cervical ganglion-10 [SCG10]). Reduced mRNA levels were confirmed by RT-PCR for MBP, ACTB and TB10. The MBP reduction was limited to transcripts containing exon 2. ACTB and TB10 mRNAs were also decreased in bipolar disorder. None of the transcripts were altered in subjects with major depression. Reduced MBP mRNA in schizophrenia replicates findings in other brain regions and is consistent with oligodendrocyte involvement in the disorder. The decreases in expression of ACTB, and the actin-binding protein gene TB10, suggest changes in cytoskeletal organisation. The findings confirm that the primary visual cortex shows molecular alterations in schizophrenia and extend the evidence for a widespread, rather than focal, cortical pathophysiology.

Young healthy male recruits of the Swiss Army participated twice, 10 weeks apart, in data collection (1st examination: n = 177; 2nd examination: n = 105). On two occasions, we assessed HCC, perceived stress and different candidate variables that may affect HCC (e.g. socioeconomic status, meteorological data). Military training increased perceived stress from the first to the second examination, but did not affect HCC. In line with this, there was no correlation between HCC and perceived stress ratings. This could be interpreted as a missing influence of mainly physical stress (e.g. exercise) on HCC. In contrast, significant correlations were found between HCC and ambient temperature, humidity and education. Future studies should control for meteorological data and educational status when examining HCC.

    There are few published familial relative risks (RR) for lethal prostate cancer. This study estimates RRs for lethal prostate cancer based on comprehensive family history data, with the goal of improving identification of those men at highest risk of dying from prostate cancer. We used a population-based genealogical resource linked to a statewide electronic SEER cancer registry and death certificates to estimate relative risks (RR) for death from prostate cancer based upon family history. Over 600,000 male probands were analyzed, representing a variety of family history constellations of lethal prostate cancer. RR estimates were based on the ratio of the observed to the expected number of lethal prostate cancer cases using internal rates. RRs for lethal prostate cancer based on the number of affected first-degree relatives (FDR) ranged from 2.49 (95% CI: 2.27, 2.73) for exactly 1 FDR to 5.30 (2.13, 10.93) for ≥3 affected FDRs. In an absence of affected FDRs, increased risk was also significant for increasing numbers of affected second-degree or third degree relatives. Equivalent risks were observed for similar maternal and paternal family history. This study provides population-based estimates of lethal prostate cancer risk based on lethal prostate cancer family history. Many family history constellations associated with two to greater than five times increased risk for lethal prostate cancer were identified. These lethal prostate cancer risk estimates hold potential for use in identification, screening, early diagnosis, and treatment of men at high risk for death from prostate cancer.

    2017-04-01

    Full Text Available the article substantiates the need to develop a basic methodology for investigating crimes related to illicit trafficking in narcotic drugs due to the fact that these crimes are inextricably linked, interdependent and can not be carried out separately from each other in principle. The existing separate private methods develop recommendations for the investigation of specific types of crimes, for example, only smuggling of these funds or their sale and they are not connected with each other. In this regard, it is not possible to trace the whole cycle of criminal activity from the introduction of controlled means to illicit trafficking prior to their sale. Therefore, the basic methodology for investigating such crimes will allow us to trace the whole chain of criminal acts and to reveal all the circumstances that affect the full and objective investigation of such crimes.

    Full Text Available Abstract Background Fanconi anemia (FA is an autosomal recessive DNA repair disorder with affected individuals having a high risk of developing acute myeloid leukaemia and certain solid tumours. Thirteen complementation groups have been identified and the genes for all of these are known (FANCA, B, C, D1/BRCA2, D2, E, F, G, I, J/BRIP1, L, M and N/PALB2. Previous studies of cancer incidence in relatives of Fanconi anemia cases have produced conflicting results. A study of British FA families was therefore carried out to investigate this question, since increases in cancer risk in FA heterozygotes would have implications for counselling FA family members, and possibly also for the implementation of preventative screening measures in FA heterozygotes. Methods Thirty-six families took part and data was collected on 575 individuals (276 males, 299 females, representing 18,136 person years. In this cohort, 25 males and 30 females were reported with cancer under the age of 85 years, and 36 cancers (65% could be confirmed from death certificates, cancer registries or clinical records. Results A total of 55 cancers were reported in the FA families compared to an estimated incidence of 56.95 in a comparable general population cohort, and the relative risk of cancer was 0.97 (95% C.I. = 0.71–1.23, p = 0.62 for FA family members. Analysis of relative risk for individual cancer types in each carrier probability group did not reveal any significant differences with the possible exception of prostate cancer (RR = 3.089 (95% C.I. = 1.09 – 8.78; Χ2 = 4.767, p = 0.029. Conclusion This study has not shown a significant difference in overall cancer risk in FA families.

    A few noteworthy exceptions notwithstanding, quantitative analyses of relational learning are most often simple descriptive measures of study outcomes. For example, studies of stimulus equivalence have made much progress using measures such as percentage consistent with equivalence relations, discrimination ratio, and response latency. Although procedures may have ad hoc variations, they remain fairly similar across studies. Comparison studies of training variables that lead to different outcomes are few. Yet to be developed are tools designed specifically for dynamic and/or parametric analyses of relational learning processes. This paper will focus on recent studies to develop (1) quality computer-based programmed instruction for supporting relational learning in children with autism spectrum disorders and intellectual disabilities and (2) formal algorithms that permit ongoing, dynamic assessment of learner performance and procedure changes to optimize instructional efficacy and efficiency. Because these algorithms have a strong basis in evidence and in theories of stimulus control, they may have utility also for basic and translational research. We present an overview of the research program, details of algorithm features, and summary results that illustrate their possible benefits. It also presents arguments that such algorithm development may encourage parametric research, help in integrating new research findings, and support in-depth quantitative analyses of stimulus control processes in relational learning. Such algorithms may also serve to model control of basic behavioral processes that is important to the design of effective programmed instruction for human learners with and without functional disabilities.

    Internet-derived health care information is increasingly accessed by patients, yet its quality and accuracy is variable and unregulated. The aim of this study was to assess the information available regarding common gastrointestinal cancers via three internet search engines (Google, Yahoo and Bing). The top 30 websites for each of the terms: oesophageal, gastric, pancreatic, colon and rectal cancer were evaluated (University of Michigan Consumer Health Website Checklist) and scored [-80 (poor) to 90 (excellent)]. The median score was 53 (-7 to 81) and was significantly higher for oesophageal (61) and pancreatic (65) cancer websites, compared with gastric (49), colon (48) and rectal cancer (50) (p = 0.014). Median scores related to charitable organisations were significantly better than academic, commercial, news agency, care provider, layperson and medical information websites collectively (79 vs. 42, p < 0.0001). Overall quality of internet-derived gastrointestinal cancer information remains poor and patients and clinicians should be aware.

    Helicobacter pylori (H. pylori), discovered in 1982, is a microaerophilic, spiral-shaped gram-negative bacterium that is able to colonize the human stomach. Nearly half of the world's population is infected by this pathogen. Its ability to induce gastritis, peptic ulcers, gastric cancer and mucosa-associated lymphoid tissue lymphoma has been confirmed. The susceptibility of an individual to these clinical outcomes is multifactorial and depends on H. pylori virulence, environmental factors, the genetic susceptibility of the host and the reactivity of the host immune system. Despite the host immune response, H. pylori infection can be difficult to eradicate. H. pylori is categorized as a group I carcinogen since this bacterium is responsible for the highest rate of cancer-related deaths worldwide. Early detection of cancer can be lifesaving. The 5-year survival rate for gastric cancer patients diagnosed in the early stages is nearly 90%. Gastric cancer is asymptomatic in the early stages but always progresses over time and begins to cause symptoms when untreated. In 97% of stomach cancer cases, cancer cells metastasize to other organs. H. pylori infection is responsible for nearly 60% of the intestinal-type gastric cancer cases but also influences the development of diffuse gastric cancer. The host genetic susceptibility depends on polymorphisms of genes involved in H. pylori-related inflammation and the cytokine response of gastric epithelial and immune cells. H. pylori strains differ in their ability to induce a deleterious inflammatory response. H. pylori-driven cytokines accelerate the inflammatory response and promote malignancy. Chronic H. pylori infection induces genetic instability in gastric epithelial cells and affects the DNA damage repair systems. Therefore, H. pylori infection should always be considered a pro-cancerous factor. PMID:28321154

    This memorandum shall provide the background for the work of the European Community Commission which is to analyze safety principles relating to redundancy. The redundancy-related basic safety principles applied in French nuclear power plants are the following: . the single-failure criterion, . provisions additional to application of the single-failure criterion. These are mainly provisions made at the design stage to minimize risks associated with common cause failures or the risks of human error which can lead to such failures: - protection against hazards of internal and external origin, - the geographical or physical separation of equipment, - the independence of electrical power supplies and distribution systems, - the additional resources and associated operating procedures making it possible to accommodate total loss of the safety systems. The scope also includes the operating rules which ensure availability of redundant safety-related equipment. The provisions relating to the single-failure criterion are detailed in Basic Safety Rule 1.3.A appended. The application of these principles proposed by the operating organization and accepted by the safety authorities for the design and operation of the standby core cooling system (System RIS) is explained

    Many patients with cancer experience moderate to severe pain that requires treatment with strong opioids, of which oxycodone and morphine are examples. Strong opioids are, however, not effective for pain in all patients, nor are they well-tolerated by all patients. The aim of this review was to assess whether oxycodone is associated with better pain relief and tolerability than other analgesic options for patients with cancer pain. To assess the effectiveness and tolerability of oxycodone for pain in adults with cancer. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE and MEDLINE In-Process (Ovid), EMBASE (Ovid), Science Citation Index, Conference Proceedings Citation Index - Science (ISI Web of Science), BIOSIS (ISI), PsycINFO (Ovid) and PubMed to March 2014. We also searched Clinicaltrials.gov, metaRegister of Controlled Trials (mRCT), EU Clinical Trials Register and World Health Organization International Clinical Trials Registry Platform (ICTRP). We checked the bibliographic references of relevant identified studies and contacted the authors of the included studies to find additional trials not identified by the electronic searches. No language, date or publication status restrictions were applied to the search. We included randomised controlled trials (parallel-group or cross-over) comparing oxycodone (any formulation or route of administration) with placebo or an active drug (including oxycodone) for cancer background pain in adults. Two authors independently extracted study data (study design, participant details, interventions and outcomes) and independently assessed the quality of the included studies according to standard Cochrane methodology. Where possible, we meta-analysed the pain intensity data using the generic inverse variance method, otherwise these data were summarised narratively along with the adverse event and patient preference data. The overall quality of the evidence for each outcome

    Incidence and mortality rates for cancer have increased dramatically in the recent 30 years in Taiwan. However, not all patients receive treatment. Treatment refusal might impair patient survival and life quality. In order to improve this situation, we proposed this study to evaluate factors that are related to refusal of treatment in cancer patients via a cancer case manager system. This study analysed data from a case management system during the period from 2010 to 2012 at a medical center in Northern Taiwan. We enrolled a total of 14,974 patients who were diagnosed with cancer. Using the PRECEDE Model as a framework, we conducted logistic regression analysis to identify independent variables that are significantly associated with refusal of therapy in cancer patients. A multivariate logistic regression model was also applied to estimate adjusted the odds ratios (ORs) with 95% confidence intervals (95%CI). A total of 253 patients (1.69%) refused treatment. The multivariate logistic regression result showed that the high risk factors for refusal of treatment in cancer patient included: concerns about adverse effects (prefuse treatment have poor survival. The present study provides evidence of factors that are related to refusal of therapy and might be helpful for further application and improvement of cancer care.

    Full Text Available Xenotropic murine leukemia virus-related virus (XMRV was first reported in 2006 in a study of human prostate cancer patients with genetic variants of the antiviral enzyme, RNase L. Subsequent investigations in North America, Europe, Asia, and Africa have either observed or failed to detect XMRV in patients (prostate cancer, chronic fatigue syndrome-myalgic encephalomyelitis (CFS-ME, and immunosuppressed with respiratory tract infections or normal, healthy, control individuals. The principal confounding factors are the near ubiquitous presence of mouse-derived reagents, antibodies and cells, and often XMRV itself, in laboratories. XMRV infects and replicates well in many human cell lines, but especially in certain prostate cancer cell lines. XMRV also traffics to prostate in a nonhuman primate model of infection. Here, we will review the discovery of XMRV and then focus on prostate cancer-related research involving this intriguing virus.

    The Basic Documentation for Psycho-Oncology (PO-Bado) is a semi-directive instrument for assessing psychosocial difficulties in cancer patients. It is based on subjective status and not on degree of symptom severity. Our objectives were to assess whether use of the PO-Bado during post-cancer-diagnosis consultations improves the quality of communication by establishing a supportive relationship between nurses and patients and to assess nurses' satisfaction of their communication skills. Data were collected from post-diagnosis 'bad-news' consultations across four Cancer treatment centres in South West France. Eleven nurses who had never used the PO-Bado ('inexperienced group') received training on the instrument (short-form). Twenty-one pre-training consultations without the PO-Bado were recorded and compared with 21 post-training consultations with the PO-Bado. Twenty consultations with four nurses with experience using the PO-Bado ('experienced group') were included for between-group comparisons. Nurses' satisfaction was evaluated through semi-directive consultations at the end of the study and completed by a visual analogue scale. We transcribed and analysed 62 consultations. We observed greater use of techniques encouraging patient expression in consultations with PO-Bado-experienced nurses (p communications skills after PO-Bado training and stated that they felt more competent, particularly for referrals to psychologists. The PO-Bado is beneficial for the quality of the communication between nurses and patients at bad-news delivery consultations and for the satisfaction of nurses with regard to their relational skills.

    Stage for stage, rectal cancer has historically been associated with inferior survival compared with colon cancer. Randomized trials of rectal cancer have generally demonstrated improvements in locoregional relapse but not survival. We compared therapy and outcomes of colon versus rectal cancer in 2 time cohorts to determine if relative improvements have occurred. Patients with resected stage II/III colorectal cancer referred to the British Columbia Cancer Agency in 1989/1990 and 2001/2002 were identified. The higher of clinical or pathologic stage was used for patients receiving preoperative chemoradiation. Disease-specific survival (DSS) and overall survival (OS) were compared for rectal and colon cancer between the 2 cohorts. Kaplan-Meier method was used for survival analysis. A total of 1427 patients were included, with 375 from 1989/1990 and 1052 from 2001/2002. Between 1989/1990 and 2001/2002 there were significant increases in the use of perioperative chemotherapy for both rectal and colon cancer (Prectal cancer. DSS significantly improved for rectal (Pcolon cancer (P=0.069). Five-year OS was significantly inferior for rectal versus colon cancer in 1989/1990 (46.1% vs. 57.2%, P=0.023) and was similar to that of colon cancer in 2001/2002 (63.7% vs. 66.2%, P=0.454). Advances in locoregional and systemic therapy significantly improved survival among patients with rectal cancer. DSS and OS are now similar between colon and rectal cancer for both stage II and III disease.

    Online cancer-related support is an under-studied resource that may serve an important function in the information seeking, care, and support of cancer patients and their families. With over 9.8 million cancer survivors (defined as anyone living with cancer) in the United States alone and the number growing worldwide, it is important to understand how they seek and use online resources to obtain the information they need, when they need it, and in a form and manner appropriate to them. These are stated cancer communication goals of the US National Cancer Institute. Our purposes are to (1) present background information about online mailing lists and electronic support groups, (2) describe the rationale and methodology for the Health eCommunities (HeC) study, and (3) present preliminary baseline data on new subscribers to cancer-related mailing lists. In particular, we describe subscribers' use of mailing lists, their reasons for using them, and their reactions to participating shortly after joining the lists. From April to August 2004, we invited all new subscribers to 10 Association of Cancer Online Resources mailing lists to complete Web-based surveys. We analyzed baseline data from the respondents to examine their perceptions about cancer-related mailing lists and to describe how cancer patients and survivors used these lists in the period shortly after joining them. Cumulative email invitations were sent to 1368 new mailing list subscribers; 293 Web surveys were completed within the allotted time frame (21.4% response rate). Most respondents were over age 50 (n = 203, 72%), white (n = 286, 98%), college graduates (n = 161, 55%), and had health insurance (n = 283, 97%). About 41% (n = 116) of new subscribers reported spending 1 to 3 hours per day reading and responding to list messages. They used the mailing lists for several reasons. Among the most frequently reported, 62% (n = 179) strongly agreed they used mailing lists to obtain information on how to deal

    2011-04-01

    Based on the uses and gratifications perspective, personality was expected to relate to violent video game play frequency and game preferences. Participants completed measures of personality and frequency of violent video game play, and identified their most frequently played video games. Results indicate that individuals higher in openness but lower in agreeableness played violent video games more frequently. In addition, more open and extroverted but less agreeable and neurotic individuals generally preferred to play video games that are more violent. Results suggest personality may be more predictive of violent video game use than traditional media use, though the predictive personality dimensions may be consistent across media types.

    Nitrites, a probable human carcinogen, generate reactive nitrogen species that may cause damage to the lung. We evaluated the association between nutritional habits related to nitrite and nitrate intake and risk of lung cancer in Mazandaran, Northern Province of Iran. In this case-control study the two groups were matched for gender and age (+/- 5 years). A semi -quantitative food frequency questionnaire (FFQ) was used to collect dietary data about nutritional habits related to nitrate, nitrite, vitamins E and C intake, from 40 lung cancer cases and 40 control subjects admitted at Mazanaran hospitals. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) for the risk of lung cancer using logistic regression. Mean score of nutritional habits in case group was significantly lower than that in control group (P less than or equal 0.001). We observed a positive association between animal sources of nitrate and nitrite intake (OR = 2.7, 95% CI: 0.13-0.96) and risk of lung cancer. Decreased risk of lung cancer was also observed with fruit intake (OR = 0.26, 95% CI: 1.3-11). Our results indicate a probable association between nutritional habits related to animal sources of nitrate and nitrite intake and the risk of lung cancer that requires to be confirmed by other studies.

    Fatigue is a serious problem for the majority of patients with cancer. In this context, several studies have shown benefits of physical activity during and following treatment. However, uncertainties remain regarding the optimal type and duration of physical activity. Therefore, this study examined the relationship between cancer-related fatigue and physical activity in the course of inpatient rehabilitation. Fatigue (Multidimensional Fatigue Inventory) and physical activity (Freiburg Questionnaire of Physical Activity) were assessed in a consecutive series of 35 patients with cancer attending oncological inpatient rehabilitation during a six-month study period. The three-week rehabilitation program included daily exercise therapy consisting of aerobic endurance training, moderate resistance training, coordination exercises, relaxation training and individual physiotherapy. At discharge, a significant improvement in each dimension of cancer-related fatigue (p=0.001-0.003) and a significant increase of physical activity levels (p=0.001) were observed. A small, but significant negative correlation was found between cancer-related fatigue and the level of physical activity (R=-0.438, p=0.004). The largest effects were associated with a weekly energy expenditure of 3000 kcal through physical activity. The results support a non-linear dose-response relationship between cancer-related fatigue and physical activity. Since this is the first study providing specific exercise recommendations for an effective treatment of cancer-related fatigue in the context of inpatient rehabilitation, further research is required to validate the observed trends.

    Hazardous air pollutants or chemical release into the environment by a variety of natural and/or anthropogenic activities may give adverse effects to human health. Air pollutants such as sulphur dioxide (SO2), nitrogen oxides (NOx), carbon monoxide (CO), heavy metals and particulate matter (PM) affect number of different human organs, especially the respiratory system. The International Agency for Research on Cancer (IARC) reported that ambient air pollution is a cause of lung cancer. Recently, the agency has classified outdoor air pollution as well as PM air pollution as Group 1 carcinogens. In addition, several epidemiological studies have shown a positive association between air pollutants to lung cancer risks and mortality. However, there are only a few studies examining the molecular effects of air pollution exposure specifically in lung cancer due to multiple challenges to mimic air pollution exposure in basic experimentation. Another major issue is the lack of adequate adjustments for exposure misclassification as air pollution may differ temporo-spatially and socioeconomically. Thus, the purpose of this paper is to review the current molecular understanding of air pollution-related lung cancer and potential future direction in this challenging yet important research field.

    Inflammatory conditions in selected organs increase the risk of cancer. An inflammatory component is present also in the microenvironment of tumors that are not epidemiologically related to inflammation. Recent studies have begun to unravel molecular pathways linking inflammation and cancer. In the tumor microenvironment, smoldering inflammation contributes to proliferation and survival of malignant cells, angiogenesis, metastasis, subversion of adaptive immunity, reduced response to hormones and chemotherapeutic agents. Recent data suggest that an additional mechanism involved in cancer-related inflammation (CRI) is induction of genetic instability by inflammatory mediators, leading to accumulation of random genetic alterations in cancer cells. In a seminal contribution, Hanahan and Weinberg [(2000) Cell, 100, 57-70] identified the six hallmarks of cancer. We surmise that CRI represents the seventh hallmark.

  11. Basic considerations for the preparation of performance testing materials as related to performance evaluation acceptance criteria

    International Nuclear Information System (INIS)

    McCurdy, D.E.; Morton, J.S.

    2001-01-01

    The preparation of performance testing (PT) materials for environmental and radiobioassay applications involves the use of natural matrix materials containing the analyte of interest, the addition (spiking) of the analyte to a desired matrix (followed by blending for certain matrices) or a combination of the two. The distribution of the sample analyte concentration in a batch of PT samples will reflect the degree of heterogeneity of the analyte in the PT material and/or the reproducibility of the sample preparation process. Commercial and government implemented radioanalytical performance evaluation programs have a variety of acceptable performance criteria. The performance criteria should take into consideration many parameters related to the preparation of the PT materials including the within and between sample analyte heterogeneity, the accuracy of the quantification of an analyte in the PT material and to what 'known' value will a laboratory's result be compared. How sample preparation parameters affect the successful participation in performance evaluation (PE) programs having an acceptance criteria established as a percent difference from a 'known' value or in PE programs using other acceptance criteria, such as the guidance provided in ANSI N42.22 and N13.30 is discussed.

    To investigate the prevalence of cancer-related fatigue and explore the relationship between resilience, positive affect, and fatigue among Chinese patients with gastric cancer. Cancer-related fatigue is the most distressing symptom reported frequently by cancer patients during both treatment and survival phases. Resilience and positive affect as vital protective factors against cancer-related fatigue have been examined, but the underlying psychological mechanisms are not well understood. A cross-sectional study. Two hundred and three gastric cancer patients were enrolled from three hospitals in China. The Cancer Fatigue Scale, the positive affect subscale of the Positive and Negative Affect Schedule and the Connor-Davidson Resilience Scale (CD-RISC10) were administered. Hierarchical linear regression modelling was conducted to examine the association between resilience and cancer-related fatigue, and the mediating effect of positive affect. The incidence of clinically relevant fatigue among patients with gastric cancer was 91.6%. Regression analysis showed that resilience was negatively associated with cancer-related fatigue, explaining 15.4% of variance in cancer-related fatigue. Mediation analysis showed that high resilience was associated with increased positive affect, which was associated with decreased cancer-related fatigue. Cancer-related fatigue is prevalent among patients with gastric cancer. Positive affect may mediate the relationship between resilience and cancer-related fatigue. Interventions that attend to resilience training and promotion of positive affect may be the focus for future clinical and research endeavours. © 2017 John Wiley & Sons Ltd.

  13. How are cancer and connective tissue diseases related to sarcoidosis?

    Science.gov (United States)

    Chopra, Amit; Judson, Marc A

    2015-09-01

    Several studies have suggested an association between sarcoidosis and cancer, and between sarcoidosis and connective tissue diseases (CTDs). In this review, we discuss the evidence supporting and refuting these associations. In terms of a cancer risk in sarcoidosis patients, the data are somewhat conflicting but generally show a very small increased risk. The data supporting an association between sarcoidosis and CTD are not as robust as for cancer. However, it appears that scleroderma is the CTD most strongly associated with sarcoidosis. There are several important clinical and research-related implications of the association of sarcoidosis and CTDs. First, rigorous efforts should be made to exclude alternative causes for granulomatous inflammation before establishing a diagnosis of sarcoidosis. Second, the association between sarcoidosis and both cancer and CTDs may yield important insights into the immunopathogenesis of all three diseases. Finally, these data provide insight in answering a common question asked by sarcoidosis patients, 'Am I at an increased risk of developing cancer?' We believe that although there is an increased (relative) risk of cancer in sarcoidosis patients compared with the general population, that increased risk is quite small (low absolute risk).

    Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome caused primarily by benign mesenchymal tumors. It has been associated with malignancies in rare cases. High serum levels of fibroblast growth factor (FGF) 23 reported in a group of patients with ovarian cancer had normal serum phosphate levels. There had been no ovarian cancer-related hypophosphatemic osteomalacia in a search of the literature. We investigated a 57-year-old woman with progressive low back pain. Clinical, biochemical, and radiological assessments were performed. The patient's serum phosphate and FGF23 levels were evaluated at baseline and after treatment for ovarian cancer. The patient presented with progressive low back pain and weight loss during the previous 6 months. Imaging studies revealed low bone mineral density and multiple suspicious spinal metastatic lesions. Laboratory examination showed hypophosphatemia, hyperphosphaturia, normocalcemia, an elevated serum alkaline phosphatase level, and an elevated serum FGF23 level. Because TIO was suspected, a tumor survey was performed, and ovarian carcinoma with multiple metastasis was detected. After surgery and chemotherapy treatments for ovarian cancer, the serum phosphate and FGF23 levels returned to normal, and the low back pain improved. To our knowledge, this is the first case of ovarian cancer-related hypophosphatemic osteomalacia reported in the literature. TIO should be considered in patients with ovarian cancer presenting with weakness, bone pain, and fractures. Investigation of TIO is appropriate when these patients present hypophosphatemia.

  18. Intolerance of uncertainty, cognitive complaints, and cancer-related distress in prostate cancer survivors.

    2015-02-01

    Prostate cancer survivors have reported cognitive complaints following treatment, and these difficulties may be associated with survivors' ongoing cancer-related distress. Intolerance of uncertainty may exacerbate this hypothesized relationship by predisposing individuals to approach uncertain situations such as cancer survivorship in an inflexible and negative manner. We investigated whether greater cognitive complaints and higher intolerance of uncertainty would interact in their relation to more cancer-related distress symptoms. This cross-sectional, questionnaire-based study included 67 prostate cancer survivors who were 3 to 5 years post treatment. Hierarchical multiple regression analyses tested the extent to which intolerance of uncertainty, cognitive complaints, and their interaction were associated with cancer-related distress (measured with the Impact of Event Scale-Revised; IES-R) after adjusting for age, education, physical symptoms, and fear of cancer recurrence. Intolerance of uncertainty was positively associated with the IES-R avoidance and hyperarousal subscales. More cognitive complaints were associated with higher scores on the IES-R hyperarousal subscale. The interaction of intolerance of uncertainty and cognitive complaints was significantly associated with IES-R intrusion, such that greater cognitive complaints were associated with greater intrusive thoughts in survivors high in intolerance of uncertainty but not those low in it. Prostate cancer survivors who report cognitive difficulties or who find uncertainty uncomfortable and unacceptable may be at greater risk for cancer-related distress, even 3 to 5 years after completing treatment. It may be beneficial to address both cognitive complaints and intolerance of uncertainty in psychosocial interventions. Copyright © 2014 John Wiley & Sons, Ltd.

    Patients seeking health information commonly use the Internet as the first source for material. Studies show that well-informed patients have increased involvement, satisfaction, and healthcare outcomes. As one-third of Americans have only basic or below basic health literacy, the National Institutes of Health and American Medical Association recommend patient-directed health resources be written at a sixth-grade reading level. This study evaluates the readability of commonly accessed online resources on lung cancer. A search for "lung cancer" was performed using Google and Bing, and the top 10 websites were identified. Location services were disabled, and sponsored sites were excluded. Relevant articles (n = 109) with patient-directed content available directly from the main sites were downloaded. Readability was assessed using 10 established methods and analyzed with articles grouped by parent website. The average reading grade level across all sites was 11.2, with a range from 8.8 (New Fog Count) to 12.2 (Simple Measure of Gobbledygook). The average Flesch Reading Ease score was 52, corresponding with fairly difficult to read text. The readability varied when compared by individual website, ranging in grade level from 9.2 to 15.2. Only 10 articles (9%) were written below a sixth-grade level and these tended to discuss simpler topics. Patient-directed online information about lung cancer exceeds the recommended sixth-grade reading level. Readability varies between individual websites, allowing physicians to direct patients according to level of health literacy. Modifications to existing materials can significantly improve readability while maintaining content for patients with low health literacy. Copyright © 2016 Elsevier Inc. All rights reserved.

    2007-03-01

    Despite a shift in the cancer culture and language used to describe individuals diagnosed with this disease, the extent to which individuals with cancer adopt a particular cancer-related identity and the impact of these identities in relation to their well-being is virtually unknown. Using a cross-sectional study design and a metropolitan tumor registry, a mail questionnaire to examine post-treatment quality of life was sent to prostate cancer (PCa) survivors. The sample consisted of 490 PCa survivors, ranging in age from 49-88 (M = 69.7; SD = 7.8), one to eight years after diagnosis. The outcome measure used in these analyses was the PANAS to assess positive and negative affect. The most frequently reported cancer-related identity was "someone who has had PCa" (57%). The least reported self view was "victim" (1%). Twenty-six percent of men self-identified as "survivors" while 6% thought of themselves as "cancer conquerors." Only 9% self-identified as a "patient." Multivariate analyses, adjusted for potential confounders, show respondents who identified themselves as "survivors" or "cancer conquerors" reported significantly higher scores on positive affect than men who self-identified as "patients" (p < .001). Although the majority of respondents identified themselves as "someone who has had cancer," identifying as a "survivor" or "someone who has conquered cancer" appears to have adaptive value for positive mood. Those who perceive themselves as survivors of prostate cancer may derive some benefit in well-being associated with this self assessment.

    Full Text Available We have previously reported hepcidin and ferritin increases in the plasma of breast cancer patients, but not in patients with benign breast disease. We hypothesized that these differences in systemic iron homeostasis may reflect alterations in different iron-related proteins also play a key biochemical and regulatory role in breast cancer. Thus, here we explored the expression of a bundle of molecules involved in both iron homeostasis and tumorigenesis in tissue samples. Enzyme-linked immunosorbent assay (ELISA or reverse-phase protein array (RPPA, were used to measure the expression of 20 proteins linked to iron processes in 24 non-cancerous, and 56 cancerous, breast tumors. We found that cancerous tissues had higher level of hepcidin than benign lesions (p = 0.012. The univariate analysis of RPPA data highlighted the following seven proteins differentially expressed between non-cancerous and cancerous breast tissue: signal transducer and transcriptional activator 5 (STAT5, signal transducer and activator of transcription 3 (STAT3, bone morphogenetic protein 6 (BMP6, cluster of differentiation 74 (CD74, transferrin receptor (TFRC, inhibin alpha (INHA, and STAT5_pY694. These findings were confirmed for STAT5, STAT3, BMP6, CD74 and INHA when adjusting for age. The multivariate statistical analysis indicated an iron-related 10-protein panel effective in separating non-cancerous from cancerous lesions including STAT5, STAT5_pY694, myeloid differentiation factor 88 (MYD88, CD74, iron exporter ferroportin (FPN, high mobility group box 1 (HMGB1, STAT3_pS727, TFRC, ferritin heavy chain (FTH, and ferritin light chain (FTL. Our results showed an association between some iron-related proteins and the type of tumor tissue, which may provide insight in strategies for using iron chelators to treat breast cancer.

    Research suggests that a cancer diagnosis predicts marital dissolution more strongly for women survivors than men, but there is a paucity of research on potential processes underlying this vulnerability. The present cross-sectional study examined whether specific cancer-related problems were associated with the odds of relationship breakup following diagnosis and whether these relationships differed between male and female cancer survivors. A national cross-sectional quality of life study assessed self-reported cancer-related problems and relationship change among survivors who were either 2, 6, or 10 years post-diagnosis (n = 6099). Bivariate analyses indicated that cancer-related problems (e.g., emotional distress) were greater for divorced/separated survivors compared to those with intact relationships and were greater for women versus men. Logistic regressions indicated that for both male and female survivors, lower income, younger age, and longer time since diagnosis were associated with greater odds of divorce or separation after diagnosis (ORs > 2.14, p emotional distress (OR = 1.14, p divorce or separation. For men only, fear of cancer recurrence was associated with greater odds of divorce or separation (OR = 1.32, p emotional or financial/employment problems attributed to the cancer diagnosis were associated with the likelihood of reporting relationship dissolution. Although directions of causality could not be ascertained, results suggest the possibility that helping male and female cancer survivors cope with specific cancer-related problems may benefit the quality and stability of their relationships with significant others following diagnosis.

    2007-01-01

    The study aimed to explore the association between the presence of several protective health behaviors and physical and mental wellbeing/functioning among healthy hospital employees in Greece. A randomly selected representative sample of 395 employees working in seven hospitals, both public and private, within the wider region of Athens participated in the study. Participants were assigned to the following professional categories: administrative, auxiliary and technical personnel, medical doctors and nurses. Four basic protective health behaviors were examined: following the Mediterranean diet, exercising, no smoking and moderate alcohol drinking. Employees' health related quality of life was assessed with the self-administered SF-36 generic health status measure. Technical and administrative hospital personnel reported more healthy behaviors than medical and auxiliary personnel. There was an increased likelihood of scoring higher in almost all SF-36 Physical health subscales in the accumulation of the above four protective heath behaviors. In terms of mental health, even the presence of two or more protective health behaviors significantly increase the score on most SF-36 Mental health subscales. Results indicate that the protective role of basic health behaviors extends beyond physical health to mental wellbeing.

    Full Text Available Background: Fatigue is the most common side effect of cancer treatment with chemotherapy and/or radiation therapy, selected biologic response modifiers. The main purpose of this study is to evaluate the effects of aerobic exercise on cancer-related fatigue in patients of the solid tumor after chemotherapy and radiotherapy. Methods: After screening for cancer-related fatigue, 34 patients fulfilled the inclusive criteria and were assigned into two groups (n = 17 recruited in the intervention group and n = 17 in control group. The intervention group received aerobic exercise program which included treadmill walking with low to moderate intensity (50%–70% of maximum heart rate, for 20–40 min/day for 5 days/week. Control group were taught stretching exercises of hamstrings, gastrocnemius, and soleus (to be done at home and were encouraged to remain active. Outcome measures such as brief fatigue inventory (BFI, 6-min walk test, and functional assessment of cancer therapy-general (FACT-G were taken at baseline and after 6-weeks. Results: The data were analyzed using the Wilcoxon matched-pairs signed rank test for within group and Mann–Whitney U-test for between group comparisons. The results of this study showed that there was a significant reduction in cancer-related fatigue BFI score (P < 0.0001,, also there was significant improvement in the physical performance as in 6-min walk distance (P < 0.0001 and quality of life, FACT-G score (P = 0.0001. Conclusion: Aerobic exercise for 6 weeks has beneficial effects on cancer-related fatigue in patients with solid tumor after chemotherapy and/or radiotherapy.

  7. Wavelet basics

    1995-01-01

    Since the study of wavelets is a relatively new area, much of the research coming from mathematicians, most of the literature uses terminology, concepts and proofs that may, at times, be difficult and intimidating for the engineer. Wavelet Basics has therefore been written as an introductory book for scientists and engineers. The mathematical presentation has been kept simple, the concepts being presented in elaborate detail in a terminology that engineers will find familiar. Difficult ideas are illustrated with examples which will also aid in the development of an intuitive insight. Chapter 1 reviews the basics of signal transformation and discusses the concepts of duals and frames. Chapter 2 introduces the wavelet transform, contrasts it with the short-time Fourier transform and clarifies the names of the different types of wavelet transforms. Chapter 3 links multiresolution analysis, orthonormal wavelets and the design of digital filters. Chapter 4 gives a tour d'horizon of topics of current interest: wave...

    At first, the basic features of LME are recalled (definition, characteristics, embrittling couples), together with classical experimental features and open questions. Then, a review of a few very recent results obtained on classical embrittling couples but using new powerful investigation techniques developed in France is proposed. Second we define LMC. The 'LME-LMC' correlation is postulated. Then we concentrate on the LME-LMC problem related to the build-up of the Liquid Metal Spallation target in the frame of the MEGAPIE project. The Russian expertise on LME is briefly mentioned. Then we present some results obtained in the frame of the Groupement de Recherche' GEDEON, focusing on steel grade T91 in contact with lead and lead-bismuth eutectic, in agreement with Russian literature.

    Home numeracy has been shown to play an important role in children’s mathematical performance. However, findings are inconsistent as to which home numeracy activities are related to which mathematical skills. The present study disentangled between various mathematical abilities that were previously masked by the use of composite scores of mathematical achievement. Our aim was to shed light on the specific associations between home numeracy and various mathematical abilities. The relationships between kindergartners’ home numeracy activities, their basic number processing and calculation skills were investigated. Participants were 128 kindergartners (Mage = 5.43 years, SD = 0.29, range: 4.88–6.02 years) and their parents. The children completed non-symbolic and symbolic comparison tasks, non-symbolic and symbolic number line estimation tasks, mapping tasks (enumeration and connecting), and two calculation tasks. Their parents completed a home numeracy questionnaire. Results indicated small but significant associations between formal home numeracy activities that involved more explicit teaching efforts (i.e., identifying numerals, counting) and children’s enumeration skills. There was no correlation between formal home numeracy activities and non-symbolic number processing. Informal home numeracy activities that involved more implicit teaching attempts, such as “playing games” and “using numbers in daily life,” were (weakly) correlated with calculation and symbolic number line estimation, respectively. The present findings suggest that disentangling between various basic number processing and calculation skills in children might unravel specific relations with both formal and informal home numeracy activities. This might explain earlier reported contradictory findings on the association between home numeracy and mathematical abilities. PMID:29623055

    The purpose of this exploratory and descriptive study is to contribute to the sparse return-to-work literature on head and neck cancer (HNC) survivors. Interview participants were asked to reflect upon their work-related experience with cancer by answering two specific questions: (1) What advice would you give someone who has been newly diagnosed with head and neck cancer? (2) What advice would you give to employers of these people? Data were gathered through 10 individual semi-structured in-depth interviews with HNC clinic patients at a regional cancer center's head and neck clinic in Ontario, Canada. A constant comparative method of theme development was used. Codes identified in and derived from the data were discussed by research team members until consensus was reached. Codes with similar characteristics were grouped together and used to develop overarching themes. Work-related advice for peers focused on personal self-care and interactions within workplaces. Work-related advice to employers focused on demonstrating basic human values as well as the importance of communication. The study results suggest HNC clinic patients should be proactive with employers and help to set reasonable expectations and provide a realistic plan for work to be successfully completed. HNC clinic patients should develop communication skills to effectively disclose their cancer and treatment to employers. In this exploratory study, HNC clinic patients' advice was solution-focused underscoring the importance of self-care and pro-active communication and planning with employers. Employers were advised to demonstrate core human values throughout all phases of the work disability episode beginning at diagnosis.

    Full Text Available Question: Does supervised physical activity reduce cancer-related fatigue? Design: Systematic review with meta-analysis of randomised trials. Participants: People diagnosed with any type of cancer, without restriction to a particular stage of diagnosis or treatment. Intervention: Supervised physical activity interventions (eg, aerobic, resistance and stretching exercise, defined as any planned or structured body movement causing an increase in energy expenditure, designed to maintain or enhance health-related outcomes, and performed with systematic frequency, intensity and duration. Outcome measures: The primary outcome measure was fatigue. Secondary outcomes were physical and functional wellbeing assessed using the Functional Assessment of Cancer Therapy Fatigue Scale, European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire, Piper Fatigue Scale, Schwartz Cancer Fatigue Scale and the Multidimensional Fatigue Inventory. Methodological quality, including risk of bias of the studies, was evaluated using the PEDro Scale. Results: Eleven studies involving 1530 participants were included in the review. The assessment of quality showed a mean score of 6.5 (SD 1.1, indicating a low overall risk of bias. The pooled effect on fatigue, calculated as a standardised mean difference (SMD using a random-effects model, was –1.69 (95% CI –2.99 to –0.39. Beneficial reductions in fatigue were also found with combined aerobic and resistance training with supervision (SMD = –0.41, 95% CI –0.70 to –0.13 and with combined aerobic, resistance and stretching training with supervision (SMD = –0.67, 95% CI –1.17 to –0.17. Conclusion: Supervised physical activity interventions reduce cancer-related fatigue. These findings suggest that combined aerobic and resistance exercise regimens with or without stretching should be included as part of rehabilitation programs for people who have been diagnosed with cancer

    Full Text Available Background: For inoperable non-small cell lung cancer combined chemotherapy and radiotherapy plays an important role as a therapeutic modality. The aim of the present study was to analyze neoadjuvant chemotherapy related acute toxicity in locally advanced lung cancer (stage IIIA and IIIB in Indian patients using Cisplatin and Etoposide combination chemotherapy. Material and methods: Forty patients of locally advanced Non small cell lung cancer received three cycles neoadjuvant chemotherapy using Injection Cisplatin and Etoposide. The patients were taken for Radical radiotherapy to a dose of 60 Gray over 30 fractions in conventional fractionation after completing chemotherapy. Chemotherapy associated toxicity was assessed using common toxicity criteria (CTC v2.0 Results: Forty patients were available for final evaluation. Median age of presentation of patients was fifty-six years. Thirteen patients had Non small cell lung cancer stage IIIA while twenty-seven patients had Stage IIIB disease. Anemia was the most common hematological toxicity observed (seen in 81% of patients. Nausea and vomiting were the most common non -hematological toxicity seen. Sensory neuropathy was seen in 38%of patients. 88% patients developed alopecia. Seven patients developed febrile neutropenias. Conclusion: Neo-adjuvant chemotherapy using Cisplatin and Etoposide continues to be a basic regimen in the Indian set up despite availability of higher molecules, since it is cost effective, well tolerated and therapeutically effective. Blood transfusions, growth factors and supportive care can be used effectively to over come toxicity associated with this regimen.

  16. Ozone depletion, related UVB changes and increased skin cancer incidence

    Kane, R. P.

    1998-03-01

    Stratospheric ozone at middle latitudes shows a seasonal variation of about +/-20%, a quasi-biennial oscillation of 1-10% range and a long-term variation in which the level was almost steady up to about 1979 and declined thereafter to the present day by about 10%. These variations are expected to be reflected in solar UVB observed at the ground, but in an opposite direction. Thus UVB should have had a long-term increase of about 10-20%, which should cause an increase in skin cancer incidence of about 20-40%. Skin cancer incidence has increased all over the world, e.g. about 90% in USA during 1974-1990. It is popularly believed that this increase in skin cancer incidence is related to the recent ozone depletion. This seems to be incorrect, for two reasons. Firstly, the observed skin cancer increase is too large (90%) compared with the expected value (40%) from ozone depletion. Secondly, cancer does not develop immediately after exposure to solar UVB. The sunburns may occur within hours; but cancer development and detection may take years, even decades. Hence the observed skin cancer increase since 1974 (no data available for earlier periods) must have occurred due to exposure to solar UVB in the 1950s and 1960s, when there was no ozone depletion. Thus, the skin cancer increase must be attributed to harmful solar UVB levels existing even in the 1960s, accentuated later not by ozone depletion (which started only much later, by 1979) but by other causes, such as a longer human life span, better screening, increasing tendencies of sunbathing at beaches, etc., in affluent societies. On the other hand, the recent ozone depletion and the associated UVB increases will certainly take their toll; only that the effects will not be noticed now but years or decades from now. The concern for the future expressed in the Montreal Protocol for reducing ozone depletion by controlling CFC production is certainly justified, especially because increased UVB is harmful to animal and

    Full Text Available More than thirty years have passed since human T-cell leukemia virus type 1 (HTLV-1 was described as the first retrovirus to be the causative agent of a human cancer, adult T-cell leukemia (ATL, but the precise mechanism behind HTLV-1 pathogenesis still remains elusive. For more than two decades, the transforming ability of HTLV-1 has been exclusively associated to the viral transactivator Tax. Thirteen year ago, we first reported that the minus strand of HTLV-1 encoded for a basic Zip factor factor (HBZ, and since then several teams have underscored the importance of this antisense viral protein for the maintenance of a chronic infection and the proliferation of infected cells. More recently, we as well as others have demonstrated that HBZ has the potential to transform cells both in vitro and in vivo. In this review, we focus on the latest progress in our understanding of HBZ functions in chronicity and cellular transformation. We will discuss the involvement of this paradigm shift of HTLV-1 research on new therapeutic approaches to treat HTLV-1-related human diseases.

    Full Text Available BackgroundCancer monitoring and prevention relies on the critical aspect of timely notification of cancer cases. However, the abstraction and classification of cancer from the free-text of pathology reports and other relevant documents, such as death certificates, exist as complex and time-consuming activities.AimsIn this paper, approaches for the automatic detection of notifiable cancer cases as the cause of death from free-text death certificates supplied to Cancer Registries are investigated.Method A number of machine learning classifiers were studied. Features were extracted using natural language techniques and the Medtex toolkit. The numerous features encompassed stemmed words, bi-grams, and concepts from the SNOMED CT medical terminology. The baseline consisted of a keyword spotter using keywords extracted from the long description of ICD-10 cancer related codes.ResultsDeath certificates with notifiable cancer listed as the cause of death can be effectively identified with the methods studied in this paper. A Support Vector Machine (SVM classifier achieved best performance with an overall F-measure of 0.9866 when evaluated on a set of 5,000 free-text death certificates using the token stem feature set. The SNOMED CT concept plus token stem feature set reached the lowest variance (0.0032 and false negative rate (0.0297 while achieving an F-measure of 0.9864. The SVM classifier accounts for the first 18 of the top 40 evaluated runs, and entails the most robust classifier with a variance of 0.001141, half the variance of the other classifiers.ConclusionThe selection of features significantly produced the most influences on the performance of the classifiers, although the type of classifier employed also affects performance. In contrast, the feature weighting schema created a negligible effect on performance. Specifically, it is found that stemmed tokens with or without SNOMED CT concepts create the most effective feature when combined with

    Genetic variations, such as single nucleotide polymorphisms (SNPs) in microRNAs (miRNA) or in the miRNA binding sites may affect the miRNA dependent gene expression regulation, which has been implicated in various cancers, including breast cancer, and may alter individual susceptibility to cancer. We investigated associations between miRNA related SNPs and breast cancer risk. First we evaluated 2,196 SNPs in a case-control study combining nine genome wide association studies (GWAS). Second, we further investigated 42 SNPs with suggestive evidence for association using 41,785 cases and 41,880 controls from 41 studies included in the Breast Cancer Association Consortium (BCAC). Combining the GWAS and BCAC data within a meta-analysis, we estimated main effects on breast cancer risk as well as risks for estrogen receptor (ER) and age defined subgroups. Five miRNA binding site SNPs associated significantly with breast cancer risk: rs1045494 (odds ratio (OR) 0.92; 95% confidence interval (CI): 0.88–0.96), rs1052532 (OR 0.97; 95% CI: 0.95–0.99), rs10719 (OR 0.97; 95% CI: 0.94–0.99), rs4687554 (OR 0.97; 95% CI: 0.95–0.99, and rs3134615 (OR 1.03; 95% CI: 1.01–1.05) located in the 3′ UTR of CASP8, HDDC3, DROSHA, MUSTN1, and MYCL1, respectively. DROSHA belongs to miRNA machinery genes and has a central role in initial miRNA processing. The remaining genes are involved in different molecular functions, including apoptosis and gene expression regulation. Further studies are warranted to elucidate whether the miRNA binding site SNPs are the causative variants for the observed risk effects. PMID:25390939

    Here we present, to the best of our knowledge, the first case of a paraneoplastic Cushing's syndrome (hypercortisolism) resulting from treatment-related neuroendocrine prostate cancer - a highly aggressive and difficult disease to treat. A 51-year-old man was started on androgen deprivation therapy after presenting with metastatic prostate cancer, characterized by diffuse osseous metastasis. Shortly thereafter, he developed progressive disease with biopsy proven neuroendocrine prostate cancer as well as symptoms of increased skin pigmentation, hypokalemia, hypertension, hyperglycemia and profound weakness, consistent with ectopic Cushing's syndrome. Molecular analysis of the patient's tumor through RNA sequencing showed high expression of several genes including CHGA, ASCL1, CALCA, HES6, PCSK1, CALCB and INSM1 confirming his neuroendocrine phenotype; elevated POMC expression was found, supporting the diagnosis of ectopic Cushing's syndrome. © 2016 The Japanese Urological Association.

    2013-04-01

    Due to developments in diagnosis and treatment of breast cancer, survival rates are rising. This leads to a population of mainly women, who also experience breast cancer-related lymphoedema (BCRL). Long after the cancer has been treated, lymphoedema persists at a time when individuals have returned to work. Large limb volumes can present a problem to these individuals and innovative treatments are needed, in order to retain as much normality as possible and reduce excessive limb volumes that patients can experience with lymphoedema long after treatment. It is also important that these treatments do not disrupt daily living and, for some, work-life balance. With the introduction of wrap around compression systems and collaborative working with the patient, it is possible to achieve an acceptable outcome to those patients with these issues. This approach leads to patient satisfaction and stabilisation of limb volume to within acceptable limits for these patients, in conjunction with the therapist.

    Prostate cancer is the most common cancer among North American and European men, but its treatment continues to be problematic owing to serious side-effects, including erectile dysfunction, urinary incontinence, and potential lower GI complications. Robotic radiosurgery offers a novel, rapid, non-invasive outpatient treatment option for prostate cancer that combines robotics, advanced image-guided motion detection, and automated real-time corrective spatial positioning with submillimeter precision. This book examines all aspects of the treatment of prostate cancer with robotic radiosurgery. After introductory sections on radiosurgery as a multidisciplinary practice and specific issues relating to prostate cancer, the important challenge posed by prostate motion when administering radiation therapy is examined in depth, with detailed discussion as to how image-guided robotic radiosurgery overcomes this problem by continously identifying the precise location of the prostate throughout the course of treatment. A further major section is devoted to a discussion of techniques and potential radiobiological and clinical advantages of hypofractionated radiation delivery by means of robotic radiosurgery systems. The book closes by discussing other emerging genitourinary applications of robotic radiosurgery. All of the authors are experts in their field who present a persuasive case for this fascinating technique. (orig.)

    The financial impact and consequences of cancer on the lives of survivors remain poorly understood. This is especially true for colorectal cancer. We investigated objective cancer-related financial stress, subjective cancer-related financial strain, and their association with health-related quality of life in colorectal cancer survivors. This was a cross-sectional postal survey. The study was conducted in Ireland, which has a mixed public-private healthcare system. Colorectal cancer survivors, diagnosed 6 to 37 months prior, were identified from the population-based National Cancer Registry. Cancer-related financial stress was assessed as impact of cancer on household ability to make ends meet and cancer-related financial strain by feelings about household financial situation since cancer diagnosis. Health-related quality of life was based on European Organisation for Research and Treatment of Cancer QLQ-C30 global health status. Logistic regression was used to identify associations between financial stress and strain and low health-related quality of life (lowest quartile, score ≤50). A total of 493 survivors participated. Overall, 41% reported cancer-related financial stress and 39% cancer-related financial strain; 32% reported both financial stress and financial strain. After adjustment for sociodemographic and clinical variables, the odds of low health-related quality of life were significantly higher in those who reported cancer-related financial stress postdiagnosis compared with those who reported no change in financial stress postcancer (OR = 2.54 (95% CI, 1.62-3.99)). The odds of low health-related quality of life were also significantly higher in those with worse financial strain postdiagnosis (OR =1.73 (95% CI, 1.09-2.72)). The OR for those with both cancer-related financial stress and financial strain was 2.59 (95% CI, 1.59-4.22). Survey responders were younger, on average, than nonresponders. Responders and nonresponders may have differed in cancer-related

    Secondary and multiple primary cancers relating radiation therapy for squamous cell carcinoma (s.c.c.) of the oral region including lip, oral cavity and oropharynx were analyzed. Out of 1,197 patients with s.c.c. treated with radiation during about 30 years from 1955 to 1983 June, 56 patients (4.7 %) were regarded as double or multiple cancer. The multiple cancer (s.c.c.) was observed frequently in the multicentric zone such as hypopharynx, esophagus and bronchus as well as in other sites of the oral cavity; 67.7 % (42 out of 62 sites). Frequency of synchronous double cancers was increased in recent ten years; 47.1 % (16/34). Careful examination to the above mentioned multicentric zone leads to early detection of secondary cancer and could be expected cure of the disease. Although possibility of radiation-induced cancer could not be ruled out as for 17 patients with late recurrence (more than 8 years), different histologic diagnosis from s.c.c. was obtained in only one (malignant fibrous histiocytoma). Therefore, it was difficult to discriminate radiation-induced cancer from late recurrence in the present study. (author)

    Previous research on psychosocial support for cancer-related concerns has primarily focused on either patients or their relatives, although limited research is available on how patients and their relatives can be supported together. The aim of this article is to explore the use of storytelling as a part of a residential cancer rehabilitation intervention for patients together with their relatives, with a specific focus on their management of cancer-related concerns. Ten pairs participated in the intervention and data were generated through ethnographic fieldwork, including participant observations, informal conversations and follow-up interviews conducted one month after completing the intervention. Analysis was performed drawing on narrative theory combined with social practice theory. The results demonstrate that the use of storytelling and metaphors intertwined with other course activities, such as dancing and arts & crafts, provided the patients and their relatives with strategies to manage cancer-related concerns, which they were later able to apply in their everyday lives. The study results may be useful to other professionals in clinical practice for rehabilitation purposes for addressing issues of fear and worry.

    The aim of this study was to evaluate the ratio of significant weakness in the affected arm of breast cancer-related lymphedema patients to their unaffected side. Another purpose was to identify factors related to arm weakness and physical function in patients with breast cancer-related lymphedema. Consecutive patients (n = 80) attended a single evaluation session following their outpatient lymphedema clinic visit. Possible independent factors (i.e., lymphedema, pain, psychological, educational, and behavioral) were evaluated. Handgrip strength was used to assess upper extremity muscle strength and the disabilities of arm, shoulder, and hand (DASH) questionnaire was used to assess upper extremity physical function. Multivariate logistic regression was performed using factors that had significant differences between the handgrip weakness and non-weakness groups. Out of the 80 patients with breast cancer-related lymphedema, 29 patients (36.3 %) had significant weakness in the affected arm. Weakness of the arm with lymphedema was not related to lymphedema itself, but was related to the fear of using the affected limb (odds ratio = 1.76, 95 % confidence interval = 1.30-2.37). Fears of using the affected limb and depression significantly contributed to the variance in DASH scores. Appropriate physical and psychological interventions, including providing accurate information and reassurance of physical activity safety, are necessary to prevent arm weakness and physical dysfunction in patients with breast cancer-related lymphedema.

    The Szent-Györgyi Prize for Progress in Cancer Research is a prestigious scientific award sponsored by the National Foundation for Cancer Research (NFCR)-a leading cancer research charitable organization in the United States that supports innovative cancer research globally with the ultimate goal to cure cancer. The coveted Szent-Györgyi Prize annually honors a scientist whose seminal discovery or body of work has resulted in, or led toward, notable contributions to cancer prevention, diagnosis, or treatment; and the discovery has had a high direct impact of saving people's lives. In addition, the prize promotes public awareness of the importance of basic cancer research and encourages the sustained investment needed to accelerate the translation of these research discoveries into new cancer treatments. In 2016, NFCR's Szent-Györgyi Prize Selection Committee was unanimous in its decision to recognize an icon in human disease genetics, Dr. Mary-Claire King, for her pioneering research that demonstrated the first evidence of genetic predisposition to breast cancer. Her proof of existence of BRCA1 gene and its location has made genetic screening for breast and ovarian cancers possible, saving lives of many people who are at high risk with inherited BRCA1 mutations.

    Using a Protection Motivation Theory (PMT) framework, this study examined whether factual colon cancer information is a meaningful source of exercise motivation for relatives of patients with colon cancer. One hundred sixty-six inactive relatives were randomly assigned to one of two treatment conditions: PMT group (intervention); and non-PMT group (attention control). At baseline (T1) participants completed demographic information, a questionnaire designed to assess their beliefs toward exercise and colon cancer as well as their exercise intentions. At T2 (one week following T1) participants watched one of two DVD videos that were created for the study. The intervention DVD contained exercise and colon cancer information that was yoked within the four major components of PMT: perceived vulnerability (PV); perceived severity (PS); response efficacy (RE); and self-efficacy (SE), while the attention control DVD contained general diet and cancer information. Immediately following watching the DVD, participants completed the same measures as in T1. Participants assigned to the PMT intervention group showed significant improvement in PV, RE, SE and exercise intentions, whereas participants assigned to the attention control group showed significant improvement only in RE. RE, SE, and PS made significant and unique contributions to prediction of exercise intention. Overall, the results of the present study demonstrate that a single exposure media intervention grounded in a PMT framework can change individuals' exercise and colon cancer beliefs, as well as change their exercise intentions. Implications of these findings and direction for future research are discussed.

    Human Papilloma Virus infection is very frequent in humans and is mainly transmitted sexually. The majority of infections are transient and asymptomatic, however, if the infection persists, it can occur with a variety of injuries to skin and mucous membranes, depending on the type of HPV involved. Some types of HPV are classified as high oncogenic risk as associated with the onset of cancer. The tumors most commonly associated with HPV are cervical and oropharyngeal cancer, epigenetic mechanisms related to HPV infection include methylation changes to host and viral DNA and chromatin modification in host species. This review is focused about epigenethic mechanism, such as MiRNAs expression, related to cervix and oral cancer. Specifically it discuss about molecular markers associated to a more aggressive phenotype. In this way we will analyze genes involved in meiotic sinaptonemal complex, transcriptional factors, of orthokeratins, sinaptogirin, they are all expressed in cancer in a way not more dependent on cell differentiation but HPV-dependent.

Research has demonstrated that with increased number of symptoms reported, breast cancer survivors' limb volume increased. Lymphedema symptoms in the affected limb may indicate a latent stage of lymphedema in which changes cannot be detected by objective measures. The latent stage of lymphedema may exist months or years before overt swelling occurs. Symptom report may play an important role in detecting lymphedema in clinical practice. The purposes of this study were to: 1 examine the validity, sensitivity, and specificity of symptoms for detecting breast cancer-related lymphedema and 2 determine the best clinical cutoff point for the count of symptoms that maximized the sum of sensitivity and specificity. Data were collected from 250 women, including healthy female adults, breast cancer survivors with lymphedema, and those at risk for lymphedema. Lymphedema symptoms were assessed using a reliable and valid instrument. Validity, sensitivity, and specificity were evaluated using logistic regression, analysis of variance, and areas under receiver operating characteristic curves. Count of lymphedema symptoms was able to differentiate healthy adults from breast cancer survivors with lymphedema and those at risk for lymphedema. A diagnostic cutoff of three symptoms discriminated breast cancer survivors with lymphedema from healthy women with a sensitivity of 94% and a specificity of 97

    Objective: To investigate the basic data of risk estimation of lung cancer among non-uranium miners in China. Methods: 2836 workers from 24 mines in 9 provinces/regions were face-to-face interviewed to collect information including age at exposure,exposure duration, cigarette smoking among others. Results: Age of the investigated non-uranium miners ranged from 17 to 72 (36.9 ± 8.0) years. The miners received low and poor education, 3% of them were illiterate, 58% with primary and middle school education, only 7% with junior college and higher education. Seventy-five percent of the uranium miners are migrant rural workers. Ethnic minority miners accoungted for 16% of all the investigated miners. Among the migrant rural workers age at initial exposure was estimated to be 29.6 ± 8.0 years. By the time of the investigation, 46.7% of the miners had worked in the mine for five years and longer, working years in the mine was 6.7 ± 6.8 years with a median of 4.1 years. 3.4% of the non-uranium miners began the initial radon exposure in mines before their 18 years of old. 17.5% of the investigated miners reported working more than 8 h every working day. Among the males, 58.0% were current smokers with a median of 16 cigarettes per day. Age to begin the cigarette smoking was 20 years on average. Current smoking rate was age-dependent, the rate as high as 69.2% for the males aged 15-19 years. Current smoking rate was significantly statistically lower in coal mines than that in other mines, 49.0% vs 62.5%. Compared with other miners, more frequent mechanical ventilations were reported by coal miners, Conclusions: In China non-uranium mines, 75% were migrant rural workers, by the time of the investigation about half of them had worked in the mines for at least five years. Non-uranium miners began their mining at 30 years on average, with a very small percentage of 3%, exposed to the mining radon before their 18 years.

    The primary aim of this paper was to evaluate the expression of extracellular matrix metalloproteinase inducer (EMMPRIN) and its relationship with proangiogenic factors and microvessel density (MVD) in ovarian cancer. The study group included 58 epithelial ovarian cancers (EOCs), 35 benign ovarian tumors, and 21 normal ovaries. The expression of EMMPRIN, vascular endothelial growth factor (VEGF), and basic fibroblast growth factor (bFGF) was assessed by ELISA of tissue homogenates. Antibodies against CD105, CD31, and CD34 were used to immunohistochemically assess MVD. We have found significantly higher EMMPRIN expression in EOC than in benign ovarian tumors and normal ovaries. Similarly, the VEGF expression was higher in EOC than in benign ovarian tumors and normal ovaries. By contrast, bFGF expression was lower in EOC than in benign ovarian tumors and ovary samples. EMMPRIN expression in EOC was directly correlated with VEGF expression and CD105-MVD, but inversely correlated with bFGF expression. Grade 2/3 ovarian cancers had increased expression of EMMPRIN and VEGF, increased CD105-MVD, and lowered expression of bFGF compared to grade 1 ovarian cancers. Moreover, EMMPRIN expression was higher in advanced (FIGO III and IV) ovarian cancer. The upregulation of EMMPRIN and VEGF expression is correlated with increased CD105-MVD and silenced bFGF, which suggests early and/or reactivated angiogenesis in ovarian cancer. Aggressive EOC is characterized by the following: high expression of EMMPRIN and VEGF, high CD105-MVD, and low expression of bFGF.

    TGF-β plays a central role in prostate cancer (PCa) bone metastasis, and it is crucial to understand the bone cell-specific role of TGF-β signaling in this process. Thus, we used knockout (KO) mouse models having deletion of the Tgfbr2 gene specifically in osteoblasts (Tgfbr2 Col1CreERT KO) or in osteoclasts (Tgfbr2 LysMCre KO). We found that PCa-induced bone lesion development was promoted in the Tgfbr2 Col1CreERT KO mice, but was inhibited in the Tgfbr2 LysMCre KO mice, relative to their respective control Tgfbr2 FloxE2 littermates. Since metastatic PCa cells attach to osteoblasts when colonized in the bone microenvironment, we focused on the mechanistic studies using the Tgfbr2 Col1CreERT KO mouse model. We found that bFGF was upregulated in osteoblasts from PC3-injected tibiae of Tgfbr2 Col1CreERT KO mice and correlated with increased tumor cell proliferation, angiogenesis, amounts of cancer-associated fibroblasts and osteoclasts. In vitro studies showed that osteoblastogenesis was inhibited, osteoclastogenesis was stimulated, but PC3 viability was not affected, by bFGF treatments. Lastly, the increased PC3-induced bone lesions in Tgfbr2 Col1CreERT KO mice were significantly attenuated by blocking bFGF using neutralizing antibody, suggesting bFGF is a promising target inhibiting bone metastasis.

    Cancer-related fatigue (CRF) is a key concern for people living with cancer and can impair physical functioning and activities of daily living. Evidence-based guidelines for CRF are available, yet inconsistently implemented globally. This study aimed to identify barriers and enablers to applying a cancer fatigue guideline and to derive implementation strategies. A mixed-method study explored the feasibility of implementing the CRF guideline developed by the Canadian Association for Psychosocial Oncology (CAPO). Health professionals, managers and consumers from different practice settings participated in a modified Delphi study with two survey rounds. A reference group informed the design of the study including the surveys. The first round focused on guideline characteristics, compatibility with current practice and experience, and behaviour change. The second survey built upon and triangulated the first round. Forty-five health practitioners and managers, and 68 cancer survivors completed the surveys. More than 75% of participants endorsed the CAPO cancer related fatigue guidelines. Some respondents perceived a lack of resources for accessible and expert fatigue management services. Further barriers to guideline implementation included complexity, limited practical details for some elements, and lack of clinical tools such as assessment tools or patient education materials. Recommendations to enhance guideline applicability centred around four main themes: (1) balancing the level of detail in the CAPO guideline with ease of use, (2) defining roles of different professional disciplines in CRF management, (3) how best to integrate CRF management into policy and practice, (4) how best to ensure a consumer-focused approach to CRF management. Translating current knowledge on optimal management of CRF into clinical practice can be enhanced by the adoption of valid guidelines. This study indicates that it is feasible to adopt the CAPO guidelines. Clinical application may

    Full Text Available There is an estimated 3 million women in the US living as breast cancer survivors and persistent cancer related fatigue (PCRF disrupts the lives of an estimated 30% of these women. PCRF is associated with decreased quality of life, decreased sleep quality, impaired cognition and depression. The mechanisms of cancer related fatigue are not well understood; however, preliminary findings indicate dysfunctional activity in the brain as a potential factor. Here we investigate the relationship between PCRF on intrinsic resting state connectivity in this population. Twenty-three age matched breast cancer survivors (15 fatigued and 8 non-fatigued who completed all cancer-related treatments at least 12 weeks prior to the study, were recruited to undergo functional connectivity magnetic resonance imaging (fcMRI. Intrinsic resting state networks were examined with both seed based and independent component analysis methods. Comparisons of brain connectivity patterns between groups as well as correlations with self-reported fatigue symptoms were performed. Fatigued patients displayed greater left inferior parietal lobule to superior frontal gyrus connectivity as compared to non-fatigued patients (P < 0.05 FDR corrected. This enhanced connectivity was associated with increased physical fatigue (P = 0.04, r = 0.52 and poor sleep quality (P = 0.04, r = 0.52 in the fatigued group. In contrast greater connectivity in the non-fatigued group was found between the right precuneus to the periaqueductal gray as well as the left IPL to subgenual cortex (P < 0.05 FDR corrected. Mental fatigue scores were associated with greater default mode network (DMN connectivity to the superior frontal gyrus (P = 0.05 FDR corrected among fatigued subjects (r = 0.82 and less connectivity in the non-fatigued group (r = −0.88. These findings indicate that there is enhanced intrinsic DMN connectivity to the frontal gyrus in breast cancer survivors with persistent

    Human papillomavirus (HPV) is the causative agent of nearly all cervical cancer cases as well as a substantial proportion of anal, vulvar, vaginal, penile and oropharyngeal cancers, making it responsible for approximately 5% of the global cancer burden. The first-generation HPV vaccines that is, quadrivalent HPV type 6/11/16/18 vaccine and bivalent HPV type 16/18 vaccine were licensed in 2006 and 2007, respectively. A second-generation 9-valent HPV type 6/11/16/18/31/33/45/52/58 vaccine with broader cancer coverage was initiated even before the first vaccines were approved. By preventing HPV infection and disease due to HPV31/33/45/52/58, the 9vHPV vaccine has the potential to increase prevention of cervical cancer from 70 to 90%. In addition, the 9vHPV vaccine has the potential to prevent 85-95% of HPV-related vulvar, vaginal and anal cancers. Overall, the 9vHPV vaccine addresses a significant unmet medical need, although further health economics and implementation research is needed.

    Relatively few studies have examined the relationship between conception of God and psychological outcomes in a self-determination theory (SDT) framework. The aim of this study was to examine the role of basic psychological needs as a mediator of the association between conception of God and psychological outcomes. In a sample of 210 religious young adults, we found that the concept of a controlling God was positively associated with feelings of need frustration and depression, whilst the concept of an autonomy-supporting God was positively associated with feelings of need satisfaction and vitality. In turn, need satisfaction promoted feelings of vitality, whereas need frustration led to feelings of depression. The satisfaction of needs was a full mediator of the relationship between autonomy-supporting God and vitality, whilst the frustration of needs was a full mediator of the relationship between controlling God and depression. These findings are discussed in terms of SDT. We also discuss how future research may further increase our understanding of the dynamics involved in concepts of God and psychological outcomes.

    ISO 8529 consists of the following parts, under the general title Reference neutron radiations: Part 1: Characteristics and methods of production; Part 2: Calibration fundamentals of radiation protection devices related to the basic quantities characterizing the radiation field; Part 3: Calibration of area and personal dosimeters and determination of response as a function of energy and angle of incidence. This Part 2. of ISO 8529 takes as its starting point the neutron sources described in ISO 8529-1. It specifies the procedures to be used for realizing the calibration conditions of radiation protection devices in neutron fields produced by these calibration sources, with particular emphasis on the corrections for extraneous effects (e.g., the neutrons scattered from the walls of the calibration room). In this part of ISO 8529, particular emphasis is placed on calibrations using radionuclide sources (clauses 4 to 6) due to their widespread application, with less details given on the use of accelerator and reactor sources (8.2 and 8.3). This part of ISO 8529 then leads to ISO 8529-3 which gives conversion coefficients and the general rules and procedures for calibration

    Recent attention has focused on the negative effects of chemotherapy on the cognitive performance of cancer survivors. The current study examined modification of this risk by catechol-O-methyltransferase (COMT) genotype based on evidence in adult populations that the presence of a Val allele is associated with poorer cognitive performance. Breast cancer survivors treated with radiotherapy (n = 58), and/or chemotherapy (n = 72), and 204 healthy controls (HCs) completed tests of cognitive performance and provided saliva for COMT genotyping. COMT genotype was divided into Val carriers (Val+; Val/Val, Val/Met) or COMT-Met homozygote carriers (Met; Met/Met). COMT-Val+ carriers performed more poorly on tests of attention, verbal fluency, and motor speed relative to COMT-Met homozygotes. Moreover, COMT-Val+ carriers treated with chemotherapy performed more poorly on tests of attention relative to HC group members who were also Val+ carriers. The results suggest that persons treated with chemotherapy for breast cancer who also possess the COMT-Val gene are susceptible to negative effects on their cognitive health. This research is important because it strives to understand the factors that predispose some cancer survivors to more negative quality-of-life outcomes. Copyright © 2010 American Cancer Society.

    2015-01-01

    The past decade has witnessed rapid advances in human genome sequencing technology and in the understanding of the role of genetic and epigenetic alterations in cancer development. These advances have raised hopes that such knowledge could lead to improvements in behavioral risk reduction interventions, tailored screening recommendations, and treatment matching that together could accelerate the war on cancer. Despite this optimism, translation of genomic discovery for clinical and public health applications has moved relatively slowly. To date, health psychologists and the behavioral sciences generally have played a very limited role in translation research. In this report we discuss what we mean by genomic translational research and consider the social forces that have slowed translational research, including normative assumptions that translation research must occur downstream of basic science, thus relegating health psychology and other behavioral sciences to a distal role. We then outline two broad priority areas in cancer prevention, detection, and treatment where evidence will be needed to guide evaluation and implementation of personalized genomics: (a) effective communication, to broaden dissemination of genomic discovery, including patient-provider communication and familial communication, and (b) the need to improve the motivational impact of behavior change interventions, including those aimed at altering lifestyle choices and those focusing on decision making regarding targeted cancer treatments and chemopreventive adherence. We further discuss the role that health psychologists can play in interdisciplinary teams to shape translational research priorities and to evaluate the utility of emerging genomic discoveries for cancer prevention and control.

    2010-01-01

    This paper presents a systematic process to check a design in order to achieve all the requirements that regulations demand. Nuclear engineers must verify that a design is done according to the safety requirements, and this paper presents how we have elaborated a process to improve the technical project verification. For a faster, better and easier verification process, here we summarize how to select the electric and mechanical basic parameters, which ensure the correct project verification of safety related design modifications. This process considers different aspects, which guarantee that the design preserves the availability, reliability and functional capability of the Structures, Systems and Components needed to operate the Nuclear Power Station with security. Electric and mechanical reference parameters are identified and discussed as well as others related ones, which are critical to safety. The implementation procedure to develop tasks performed in any company that has a quality plan is a requirement. On the engineering business, it is important not to use the personal criteria to do a technical analysis of a project; although, many times it is the checker's criteria and knowledge responsibility to ensure the correct development of a design modification. Then, the checker capabilities are the basis of the modification verification. This kind of procedure's development is not easy, because in an engineering project with important technical contents, there are multiple scenarios, but lots of them have a common basis. If we can identify the technical common basis of these projects, we will make good project verification but there are many difficulties we can encounter along this process. (authors)

    Posttraumatic stress symptoms (PTSS) can be triggered by a diagnosis of a potentially life-threatening illness such as cancer. Little is known about the impact of cancer-related PTSS symptoms on self-management behaviors for comorbid chronic medical conditions such as diabetes mellitus (DM). We recruited patients with DM and a recent diagnosis of early-stage cancer from 2 medical centers in New York City. Cancer-related PTSS were assessed using the Impact of Events Scale (score ≥ 26). DM self-management behaviors (medication adherence, exercise, healthy diet, and glucose testing) were measured 3 months later. Logistic regression was used to assess the association between cancer-related PTSS symptoms and DM self-management behaviors, adjusting for gender, marital status, and anxiety symptoms. Of 56 participants recruited, 33% reported cancer-related PTSS symptoms. Elevated cancer-related PTSS symptoms were associated with lack of healthy diet (odds ratio: 0.08, 95% confidence interval: 0.01-0.62). Early-stage cancer survivors with cancer-related PTSS symptoms were less likely to adhere to some DM self-management behaviors. Providers should recognize the impact of cancer-related PTSS symptoms to better support comorbid disease management in cancer survivors. Copyright © 2017 John Wiley & Sons, Ltd.

    Full Text Available The feasibility of the Minimum Basic Data Set (MBDS as a tool in cancer research was explored monitoring its incidence through the detection of spatial clusters. Case-control studies based on MBDS and marked point process were carried out with the focus on the residence of patients from the Prince of Asturias University Hospital in Alcalá de Henares (Madrid, Spain. Patients older than 39 years with diagnoses of stomach, colorectal, lung, breast, prostate, bladder and kidney cancer, melanoma and haematological tumours were selected. Geocoding of the residence address of the cases was done by locating them in the continuous population roll provided by the Madrid Statistical Institute and extracting the coordinates. The geocoded control group was a random sample of 10 controls per case matched by frequency of age and sex. To assess case clusters, differences in Ripley K functions between cases and controls were calculated. The spatial location of clusters was explored by investigating spatial intensity and its ratio between cases and controls. Results suggest the existence of an aggregation of cancers with a common risk factor such as tobacco smoking (lung, bladder and kidney cancers. These clusters were located in an urban area with high socioeconomic deprivation. The feasibility of designing and carrying out case-control studies from the MBDS is shown and we conclude that MBDS can be a useful epidemiological tool for cancer surveillance and identification of risk factors through case-control spatial point process studies.

    Cancer-related fatigue is the most prevalent and distressing symptom experienced by adolescents and young adults (AYAs). An electronic survey was undertaken to ascertain current fatigue management and perceptions of its effectiveness. Eighty-five percent of responders (68/80) experienced fatigue, and it was worse more than 1 year after cancer treatment ended, compared to fatigue management. Although advice to exercise was the most frequent intervention, the greatest impact of fatigue was on the ability to exercise and most did not find exercise advice helpful. Early intervention is warranted, supporting AYAs to persevere with increasing activity.

    Full Text Available There is limited evidence on the association between adherence to guidelines for cancer survivors and health-related quality of life (HRQoL. In a cross-sectional study of Korean breast cancer survivors, we examined whether adherence to the guidelines of the American Cancer Society (ACS and World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR for cancer survivors was related to levels of HRQoL, assessed by the Korean version of Core 30 (C30 and Breast cancer module 23 (BR23 of the European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire (EORTC-QLQ. We included a total of 160 women aged 21 to 79 years who had been diagnosed with breast cancer according to American Joint Committee on Cancer (AJCC stages I to III and had breast cancer surgery at least six months before the interview. Increasing adherence to ACS guidelines was associated with higher scores of social functioning (p for trend = 0.05, whereas increasing adherence to WCRF/AICR recommendations was associated with higher scores of arm symptoms (p for trend = 0.01. These associations were limited to those with stage II or III cancer. Diet may be an important factor in relation to quality of life among Korean breast cancer survivors, however our findings warrant further prospective studies to evaluate whether healthy diet improves survivors’ quality of life.

  11. Cancer-related aspects of regeneration research: a review

    International Nuclear Information System (INIS)

    Donaldson, D.J.; Mason, J.M.

    1975-01-01

    Tissue regeneration is simply the replacement of lost cells of a tissue by those remaining. Epimorphic regeneration involves dedifferentiation of many tissues and their organization into a blastema which eventually differentiates into the missing part, usually an appendage. A detailed comparison of the cell membrane changes occurring in epimorphic regeneration, tissue regeneration and cancer can contribute to greater understanding of the differences between normal and tumor cells. Further, there is evidence that epimorphic regeneration fields may in some instances suppress tumor induction and control existing tumors. This influence may be mediated by bioelectric fields, which are ubiquitous in nature and appear to control many cellular events. Disruption of these bioelectric fields suppresses epimorphic regeneration and may lead to cancer in mammals, while applied electric fields alter regenerative events and cause tumor regression. Studies on x-radioinduced regeneration suppression in relation to mutagenesis are also reviewed

    Hayes, R B; Gerin, M; Raatgever, J W; de Bruyn, A

    1986-10-01

    A case-control study was conducted to examine the relations between type of woodworking and the extent of wood dust exposure to the risks for specific histologic types of sinonasal cancer. In cooperation with the major treatment centers in the Netherlands, 116 male patients newly diagnosed between 1978 and 1981 with primary malignancies of epithelial origin of this site were identified for study. Living controls were selected from the municipal registries, and deceased controls were selected from the national death registry. Interviews were completed for 91 (78%) cases and 195 (75%) controls. Job histories were coded by industry and occupation. An index of exposure was developed to classify the extent of occupational exposure to wood dust. When necessary, adjustment was made for age and usual cigarette use. The risk for nasal adenocarcinoma was elevated by industry for the wood and paper industry (odds ratio (OR) = 11.9) and by occupation for those employed in furniture and cabinet making (OR = 139.8), in factory joinery and carpentry work (OR = 16.3), and in association with high-level wood dust exposure (OR = 26.3). Other types of nasal cancer were not found to be associated with wood-related industries or occupations. A moderate excess in risk for squamous cell cancer (OR = 2.5) was associated with low-level wood dust exposure; however, no dose-response relation was evident. The association between wood dust and adenocarcinoma was strongest for those employed in wood dust-related occupations between 1930 and 1941. The risk of adenocarcinoma did not appear to decrease for at least 15 years after termination of exposure to wood dust. No cases of nasal adenocarcinoma were observed in men whose first exposure to wood dust occurred after 1941.

  14. Nuclear energy - Reference beta-particle radiation - Part 2: Calibration fundamentals related to basic quantities characterizing the radiation field

    International Nuclear Information System (INIS)

    2004-01-01

    ISO 6980 consists of the following parts, under the general title Nuclear energy - Reference beta-particle radiation: Part 1: Method of production; Part 2: Calibration fundamentals related to basic quantities characterizing the radiation field; Part 3: Calibration of area and personal dosimeters and determination of their response as a function of energy and angle of incidence. This part 2 of ISO 6980 specifies methods for the measurement of the directional absorbed-dose rate in a tissue-equivalent slab phantom in the ISO 6980 reference beta-particle radiation fields. The energy range of the beta-particle-emitting isotopes covered by these reference radiations is 0.066 to 3.54 MeV (maximum energy). Radiation energies outside this range are beyond the scope of this standard. While measurements in a reference geometry (depth of 0.07 mm at perpendicular incidence in a tissue-equivalent slab phantom) with a reference class extrapolation chamber are dealt with in detail, the use of other measurement systems and measurements in other geometries are also described, although in less detail. The ambient dose equivalent, H*(10) as used for area monitoring of strongly penetrating radiation, is not an appropriate quantity for any beta radiation, even for that penetrating a 10 mm thick layer of ICRU tissue (i.e. E max > 2 MeV). If adequate protection is provided at 0.07 mm, only rarely will one be concerned with other depths, for example 3 mm. This document is geared towards organizations wishing to establish reference-class dosimetry capabilities for beta particles, and serves as a guide to the performance of dosimetry with the reference class extrapolation chamber for beta-particle dosimetry in other fields. Guidance is also provided on the statement of measurement uncertainties

  15. Molecular Basis of Alcohol-Related Gastric and Colon Cancer.

    2017-05-24

    Many meta-analysis, large cohort studies, and experimental studies suggest that chronic alcohol consumption increases the risk of gastric and colon cancer. Ethanol is metabolized by alcohol dehydrogenases (ADH), catalase or cytochrome P450 2E1 (CYP2E1) to acetaldehyde, which is then further oxidized to acetate by aldehyde dehydrogenase (ALDH). Acetaldehyde has been classified by the International Agency for Research on Cancer (IARC) as a Group 1 carcinogen to humans. The acetaldehyde level in the stomach and colon is locally influenced by gastric colonization by Helicobacter pylori or colonic microbes, as well as polymorphisms in the genes encoding tissue alcohol metabolizing enzymes, especially ALDH2. Alcohol stimulates the uptake of carcinogens and their metabolism and also changes the composition of enteric microbes in a way to enhance the aldehyde level. Alcohol also undergoes chemical coupling to membrane phospholipids and disrupts organization of tight junctions, leading to nuclear translocation of β-catenin and ZONAB, which may contributes to regulation of genes involved in proliferation, invasion and metastasis. Alcohol also generates reactive oxygen species (ROS) by suppressing the expression of antioxidant and cytoprotective enzymes and inducing expression of CYP2E1 which contribute to the metabolic activation of chemical carcinogens. Besides exerting genotoxic effects by directly damaging DNA, ROS can activates signaling molecules involved in inflammation, metastasis and angiogenesis. In addition, alcohol consumption induces folate deficiency, which may result in aberrant DNA methylation profiles, thereby influencing cancer-related gene expression.

    Objective: To determine the frequency of central venous catheter-related bloodstream infections (CR-BSI) in cancer patients and the antimicrobial susceptibility pattern of the isolates. Subjects and Methods: Cancer patients requiring short or long-term central venous catheterization at the time of admission or thereafter were included. Catheter tips on removal were cultured quantitatively; specimens of blood and pus were cultured qualitatively. Isolates were identified and antimicrobial susceptibility testing was performed by standard techniques. Results: Eighty-nine patients were included in the study. The frequency of CR-BSI was 17%. Out of the 19 organisms isolated, 10 (53%) were Gram-positive cocci, 8 (42%) were Gram-negative rods and 1 (5%) was a fungus. Coagulase negative staphylococci (27%) were the predominant pathogens. Among the staphylococci, 46% of the isolates were methicillin-resistant. All Gram-positive isolates were susceptive to glycopeptides. Gram-negative rods were resistant to most of the commonly used antimicrobial groups. Conclusion: Central venous catheter is an important source of bloodstream infections in cancer patients. Most of the infections are caused by Gram-positive cocci. Rigorous infection control measures and continuous surveillance is required to curb the frequency of these infections. (author)

  17. Cancer-related communication, relationship intimacy, and psychological distress among couples coping with localized prostate cancer.

    Manne, Sharon; Badr, Hoda; Zaider, Talia; Nelson, Christian; Kissane, David

    2010-03-01

    The present study evaluated intimacy as a mechanism for the effects of relationship-enhancing (self-disclosure, mutual constructive communication) and relationship-compromising communication (holding back, mutual avoidance, and demand-withdraw communication) on couples' psychological distress. Seventy-five men diagnosed with localized prostate cancer in the past year and their partners completed surveys about communication, intimacy, and distress. Multi-level models with the couple as unit of analyses indicated that the association between mutual constructive communication, mutual avoidance, and patient demand-partner withdraw and distress could be accounted for by their influence on relationship intimacy. Intimacy did not mediate associations between self-disclosure, holding back, and partner demand-patient withdraw communication and distress. These findings indicate that the way in which couples talk about cancer-related concerns as well as the degree to which one or both partners avoid talking about cancer-related concerns can either facilitate or reduce relationship intimacy, and that it is largely by this mechanism that these three communication strategies impact psychological distress. Relationship intimacy and how patients and partners communicate to achieve this intimacy is important for the psychological adjustment of early stage prostate cancer survivors and their partners.

  18. Lower heart rate variability is associated with cancer-related fatigue in breast cancer survivors

    2012-09-01

    Full Text Available Background : Fatigue is the most common and distressing symptom reported by breast cancer survivors and yet the pathophysiology of cancer-related fatigue remains largely unknown. Fatigue is associated with lower parasympathetic and higher sympathetic nervous system activity in non-cancer samples, but only one study has demonstrated this same relationship in breast cancer survivors. This study evaluates the relationship between fatigue and basal autonomic nervous system activity as measured by heart rate variability (HRV in a sample of breast cancer survivors. Methods : Women who had been diagnosed with early stage breast cancer before the age of 50 were recruited from the UCLA tumor registry and completed psychological questionnaires, including measures of fatigue. A subset of these women (n=30 participated in a follow-up study in which they completed measures of fatigue, energy and mood four times per day for 5 days using electronic diaries, provided 3 days of saliva samples for cortisol assessment and underwent physiological assessment including electrocardiogram (ECG. HRV was assessed via ECG R-R wave spectral and time sequence analysis. Results : Questionnaire measures of fatigue were negatively associated with indices of parasympathetic nervous system activity, B= − 3.85, p = 0.04 for RMSSD (root of the mean squared difference of successive normal to normal waves and B= − 76.97, p = 0.04 for LF power % (low-frequency wave power percentage. Daily fatigue was also associated with lower basal HRV, B= − 15.1, p = 0.04 for RMSSD. However, fatigue indices were not associated with sympathetic nervous system activity as measured by low- to high-frequency wave ratio. Of note, fatigue was not associated with average daily cortisol output (AUC. Conclusions : Lower HRV has been associated with increased chronic inflammation, which is elevated in cancer survivors reporting persistent fatigue, thus providing insight into

    Sixty percent of cancer survivors are 65years of age or older. Cancer and its treatments lead to cancer-related fatigue and many other side effects, in turn, creating substantial global side-effect burden (total burden from all side effects) which, ultimately, compromises functional independence and quality of life. Various modes of exercise, such as yoga, reduce cancer-related fatigue and global side-effect burden in younger cancer survivors, but no studies have specifically examined the effects of yoga on older cancer survivors. The purpose of this study was to assess the effects of a 4-week yoga intervention (Yoga for Cancer Survivors: YOCAS©®) on overall cancer-related fatigue, and due to its multidimensional nature, the subdomains of cancer-related fatigue (general, physical, emotional, and mental) and global side-effect burden in older cancer survivors. We conducted a secondary analysis on data from a multicenter phase III randomized controlled clinical trial with 2 arms (standard care and standard care plus a 4-week YOCAS©® intervention). The sample for this secondary analysis was 97 older cancer survivors (≥60years of age), between 2months and 2years post-treatment, who participated in the original trial. Participants in the YOCAS©® intervention arm reported significantly lower cancer-related fatigue, physical fatigue, mental fatigue, and global side-effect burden than participants in the standard care arm following the 4-week intervention period (peffective standardized yoga intervention for reducing cancer-related fatigue, physical fatigue, mental fatigue, and global side-effect burden among older cancer survivors.

    Peng, Lihua; Min, Su; Zejun, Zhou; Wei, Ke; Bennett, Michael I

    2015-06-29

    This is an update of a review first published in The Cochrane Library in Issue 3, 2013. Cancer-related pain places a heavy burden on public health with related high expenditure. Severe pain is associated with a decreased quality of life in patients with cancer. A significant proportion of patients with cancer-related pain are under-treated. There is a need for more effective control of cancer-related pain. Spinal cord stimulation (SCS) may have a role in pain management. The effectiveness and safety of SCS for patients with cancer-related pain is currently unknown. This systematic review evaluated the effectiveness of SCS for cancer-related pain compared with standard care using conventional analgesic medication. We also appraised risk and potential adverse events associated with the use of SCS. This is an update of a review first published in The Cochrane Library in Issue 3, 2013. The search strategy for the update was the same as in the original review. We searched the following bibliographic databases in order to identify relevant studies: the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library; MEDLINE; EMBASE; and CBM (Chinese Biomedical Database) in October 2014. We also handsearched relevant journals. There were no language restrictions. We planned to include randomised controlled trials (RCTs) that directly compared SCS with other interventions with regards to the effectiveness of pain management. We also planned to include cross-over trials that compared SCS with another treatment. We planned to identify non-randomised controlled trials but these would only be included if no RCTs could be found. The literature search for the update of this review found 121 potentially eligible articles. The initial search strategy yielded 430 articles. By scrutinising titles and abstracts, we found 412 articles irrelevant to the analytical purpose of this systematic review due to different scopes of diseases or different methods of intervention

  3. Is there an increased risk of cancer among spouses of patients with an HPV-related cancer: A systematic review.

    High-risk human papillomaviruses (HR-HPV) are the cause of most ano-genital cancers and a fast growing subset of oropharyngeal cancer. As these malignancies occur as a result of an HPV- infection transmitted through intimate contact, many patients with HPV- induced cancer and their partners are concerned about HPV-transmission and the potential partners' cancer risk. Few studies have addressed this issue and whether the HPV-related cancer risk of partners of patients with HPV-related cancers is comparable to or greater than that of the general population. We performed a systematic review of the published literature addressing this issue. Out of 1055 references screened, 53 articles were found eligible for inclusion. Regarding the issue of coincidence of HPV-induced oropharyngeal and/or anogenital cancers in couples, 13 case-reports or case-series were reported and 9 larger studies based on population-registries. Four of these registry studies showed an increased risk of cervical cancer in the partner while four did not. Among the four positive studies, odds ratios for the development of HPV-related cancer among spouses were between 2.6 and 6.7. One study showed an increased risk of tongue or tonsil cancer among husbands of women with cervical dysplasia or cancer. Overall the absolute risk increase in all these studies was small, on the order of 1-3%, although potentially underestimated. Indeed, all these studies have assessed partner's cancer risk at only one anatomical site whereas HPV- related malignancies can affect different locations. This systematic review suggests a small trend of increase risk in HPV-associated cancers among spouses of patients with HPV-related cancer. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2001-01-01

    Background and purpose: Anaemia is known to influence prognosis of head and neck cancer patients, but how anaemia and tumour growth influences each other is not clear. The present study investigates the relation of erythrocyte and iron indices of oral cancer patients to primary tumour size (Tsize), invasiveness and lymph node involvement. Materials and methods: The haemoglobin (Hb), erythrocyte count (RBC), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), Serum iron (SFe), transferrin iron-binding capacity (TIBC) and transferrin saturation (%Fe) were evaluated in 217 untreated patients with epidermoid cancer of the bucco-gingivo-palatine area. The association of erythrocyte and iron indices with sex, tumour size groups, invasion of adjacent structures and lymph node involvement, as well as the relation of SFe to Hb were analyzed. Results: Most of the patients were anaemic in terms of Hb (63%), RBC (43%) and PCV (48.4%) but almost all had normal or higher MCH (97.3%) and MCV (93.3%) though MCHC was less than normal in 70.7%. Normal or higher SFe was seen in nearly 70% and TIBC in 45% of patients. Hb, RBC and PCV were significantly lower in women, but there was no difference between men and women in the case of MCV, MCH and MCHC. Primary tumour size showed negative association with Hb, RBC and PCV but positive association with MCH ( 4 cm: 31. 7 pg; P=0.04) and MCHC ( 4 cm: 32.1; P=0.006). MCV, SFe, TIBC and %Fe did not show any relation to primary tumour size. None of the indices had any relation to invasion of adjacent structures or lymph node involvement. MCH, MCHC and MCV were not different in men and women but women had significantly lower Hb, RBC and PCV. The SFe showed poor correlation with Hb. Conclusions: The negative association of Hb, RBC and PCV with tumour size is most likely due to chronic RBC destruction, probably tumour induced, with the products of

    Cancer-related fatigue (CRF) is a common and one of the most severe symptom in the period of onset, diagnosis, treatment and rehabilitation process of cancer. But there are no confirmed measures to relieve this problem at present. Traditional Chinese medical comprehensive therapy has its advantages in dealing with this condition. Based on the research status of CRF, the following problems have been analyzed and solved: the term of CRF has been defined and recommended, and the definition has been made clear; the disease mechanism is proposed, i.e. healthy qi has been impaired in the long-term disease duration, in the process of surgery, chemotherapy, radiotherapy and biology disturbing; it is clear that the clinical manifestations are related to six Chinese medicine patterns: decreased functioning of the Pi (Spleen) and Wei (Stomach), deficiency of the Pi with dampness retention, deficiency of the Xin (Heart) and Pi, disharmony between the Gan (Liver) and Pi, deficiency of the Pi and Shen (Kidney), and deficiency of the Fei (Lung) and Shen. Based on its severity, the mild patients are advised to have non-drug psychological intervention and sleep treatment in cooperation with appropriate exercise; diet therapy are recommended to moderate patients together with sleep treatment and acupuncture, severe patients are recommended to have herbal treatment based on pattern differentiation together with physiological sleep therapy.

    1998-04-16

    A cDNA representational difference analysis (cDNA-RDA) and an arrayed filter technique were used to characterize transformation-related genes in oral cancer. From an initial comparison of normal oral epithelial cells and a human papilloma virus (HPV)-immortalized oral epithelial cell line, we obtained 384 differentially expressed gene fragments and arrayed them on a filter. Two hundred and twelve redundant clones were identified by three rounds of back hybridization. Sequence analysis of the remaining clones revealed 99 unique clones corresponding to 69 genes. The expression of these transformation related gene fragments in three nontumorigenic HPV-immortalized oral epithelial cell lines and three oral cancer cell lines were simultaneously monitored using a cDNA array hybridization. Although there was a considerable cell line-to-cell line variability in the expression of these clones, a reliable prediction of their expression could be made from the cDNA array hybridization. Our study demonstrates the utility of combining cDNA-RDA and arrayed filters in high-throughput gene expression difference analysis. The differentially expressed genes identified in this study should be informative in studying oral epithelial cell carcinogenesis.

    This guide defines recommendations made by the ASN regarding the sanitation methodology to be applied to buildings and structures of any basic nuclear installation. After a recall of the general doctrine for the management of wastes in basic nuclear installations, the guide presents the ASN doctrine for structure sanitation which distinguishes complete sanitation, extended sanitation, and sanitation in operation phase. It presents principles for the sanitation of component structures of an area of possible production of nuclear wastes. It indicates administrative procedures to be applied before and after sanitation works, notably when the radiological condition of structures has been made compatible or not with any use. After indication of requirements in terms of quality insurance, modalities of definition of defence lines (from first to fourth) are discussed. Requirements regarding the performance of sanitation operations are reviewed

  18. What Are the Relative Macroeconomic Merits and Environmental Impacts of Direct Job Creation and Basic Income Guarantees?

    Directory of Open Access Journals (Sweden)

    Pavlina R. Tcherneva

    2017-06-01

    Full Text Available There is a body of literature that favors universal and unconditional public assurance policies over those that are targeted and means-tested. Two such proposals—the basic income proposal and job guarantees—are discussed here. The paper evaluates the impact of each program on macroeconomic stability, arguing that direct job creation has inherent stabilization features that are lacking in the basic income proposal. A discussion of modern finance and labor market dynamics renders the latter proposal inherently inflationary, and potentially stagflationary. After studying the macroeconomic viability of each program, the paper elaborates on their environmental merits. It is argued that the “green” consequences of the basic income proposal are likely to emerge, not from its modus operandi, but from the tax schemes that have been advanced for its financing. By contrast, the job guarantee proposal can serve as an institutional vehicle for achieving various environmental goals by explicitly targeting environmental rehabilitation, conservation, and sustainability. Finally, in the hope of consensus building, the paper advances a joint policy proposal that is economically viable, environmentally friendly, and socially just.

    To examine the relationship between cancer-related fatigue (CRF) and physical activity in daily living in premenopausal disease-free cervical and endometrial cancer survivors. A physical activity monitor was used to collect objective data on daily physical activity. CRF and related variables were measured using self-report scales in a cross-sectional manner. The average age was 44.9 years among 64 women. The higher CRF group comprised 22 women (34%), 10% of whom had severe fatigue. The participants had higher physical activity levels compared with the findings in previous studies, and reported an average of 40 min/day of moderate to vigorous activity. Moderate to vigorous levels of physical activity were derived from essential social activities rather than leisure time exercise. There were no significant differences in physical activity levels between the lower and higher CRF groups. Our study results suggested that the higher level of physical activity in daily living itself had no relationship with decreasing CRF among premenopausal cervical and endometrial cancer survivors. It would be better to focus on cognitive and psychological factors before introducing physical activity programs and be careful of the characteristics of the participants' physical activity among this population in daily basis.

    The temporal distribution of exposure-related cancers is relevant to the study of carcinogenic mechanisms. Statistical methods for extracting pertinent information from time-to-tumor data, however, are not well developed. Separation of incidence from 'latency' and the contamination of background cases are two problems. In this paper, we present methods for estimating both the conditional distribution given exposure-related cancers observed during the study period and the unconditional distribution. The methods adjust for confounding influences of background cases and the relationship between time to tumor and incidence. Two alternative methods are proposed. The first is based on a structured, theoretically derived model and produces direct inferences concerning the distribution of interest but often requires more-specialized software. The second relies on conventional modeling of incidence and is implemented through readily available, easily used computer software. Inferences concerning the effects of radiation dose and other covariates, however, are not always obtainable directly. We present three examples to illustrate the use of these two methods and suggest criteria for choosing between them. The first approach was used, with a log-logistic specification of the distribution of interest, to analyze times to bone sarcoma among a group of German patients injected with 224 Ra. Similarly, a log-logistic specification was used in the analysis of time to chronic myelogenous leukemias among male atomic-bomb survivors. We used the alternative approach, involving conventional modeling, to estimate the conditional distribution of exposure-related acute myelogenous leukemias among male atomic-bomb survivors, given occurrence between 1 October 1950 and 31 December 1985. All analyses were performed using Poisson regression methods for analyzing grouped survival data. (J.P.N.)

    Every cancer-related death in someone of working age represents an economic loss to society. To inform priorities for cancer control, we estimated costs of lost productivity due to premature cancer-related mortality across Europe, for all cancers and by site, gender, region and country. Cancer deaths in 2008 were obtained from GLOBOCAN for 30 European countries across four regions. Costs were valued using the human capital approach. Years of productive life lost (YPLL) were computed by multiplying deaths between 15 and 64 years by working-life expectancy, then by country-, age- and gender-specific annual wages, corrected for workforce participation and unemployment. Lost productivity costs due to premature cancer-related mortality in Europe in 2008 were €75 billion. Male costs (€49 billion) were almost twice female costs (€26 billion). The most costly sites were lung (€17 billion; 23% of total costs), breast (€7 billion; 9%) and colorectum (€6 billion; 8%). Stomach cancer (in Southern and Central-Eastern Europe) and pancreatic cancer (in Northern and Western Europe) were also among the most costly sites. The average lost productivity cost per cancer death was €219,241. Melanoma had the highest cost per death (€312,798), followed by Hodgkin disease (€306,628) and brain and CNS cancer (€288,850). Premature mortality costs were 0.58% of 2008 European gross domestic product, highest in Central-Eastern Europe (0.81%) and lowest in Northern Europe (0.51%). Premature cancer-related mortality costs in Europe are significant. These results provide a novel perspective on the societal cancer burden and may be used to inform priority setting for cancer control. © 2014 UICC.

    This investigation is based on images obtained from healthy tissue and skin cancer lesions and their fluorescent spectra of cutaneous lesions derived after optical stimulation. Our analyses show that the lesions’ spectra of are different of those, obtained from normal tissue and the differences depend on the type of cancer. We use a comparison between these “healthy” and “unhealthy” spectra to define forms of variations and corresponding diseases. However, the value of the emitted light varies not only between the patients, but also depending on the position of the tested area inside of one lesion. These variations could be result from two reasons: different degree of damaging and different thickness of the suspicious lesion area. Regarded to the visible image of the lesion, it could be connected with the chroma of colour of the tested area and the lesion homogeneity that corresponds to particular disease. For our investigation, images and spectra of three non-melanoma cutanous malignant tumors are investigated, namely—basal cell carcinoma, squamous cell carcinoma, and keratoacanthoma. The images were processed obtaining the chroma by elimination of the background—healthy tissue, and applying it as a basic signal for transformation from RGB to Lab colorimetric model. The chroma of the areas of emission is compared with the relative value of fluorescence spectra. Specific spectral features are used to develop hybrid diagnostic algorithm (including image and spectral features) for differentiation of these three kinds of malignant cutaneous pathologies.

    This review summarizes the current literature on cancer-related cognitive impairment (CRCI) with a focus on prevalence, mechanisms, and possible interventions for CRCI in those who receive adjuvant chemotherapy for non-central nervous system tumors and is primarily focused on breast cancer. CRCI is characterized as deficits in areas of cognition including memory, attention, concentration, and executive function. Development of CRCI can impair quality of life and impact treatment decisions. CRCI is highly prevalent; these problems can be detected in up to 30% of patients prior to chemotherapy; up to 75% of patients report some form of CRCI during treatment, and CRCI is still present in up to 35% of patients many years following completion of treatment. While the trajectory of CRCI is becoming better understood, the mechanisms underlying the development of CRCI are still obscure; however, host characteristics, immune dysfunction, neural toxicity, and genetics may play key roles in the development and trajectory of CRCI. Intervention research is limited, though strategies to maintain function are being studied with promising preliminary findings. This review highlights key research being conducted in these areas, both in patient populations and in animals, which will ultimately result in better understanding and effective treatments for CRCI.

    The role of human papillomavirus (HPV) infection in oropharyngeal cancer (SCC) is well established. The annual incidence of oropharyngeal SCC in Israel is considerably lower than that in the United States. The purpose of this study was to assess the rate of HPV-related oropharyngeal SCC in Israel. The cohort included patients with oropharyngeal SCC who were treated during 1999 to 2011 in Israel. HPV typing was carried out using reverse hybridization and immunohistochemistry. Of the 74 patients analyzed, 25 (33.7%) had detectable HPV DNA. Patients in the HPV-positive group tended to be younger, with a higher rate of nodal metastases, and no history of smoking (p Israel as approximately 3-fold lower than in Western countries. Low exposure to HPV-16, a lower rate of transformation, to cancer or protective genetic factors may contribute to the lower rate of oropharyngeal SCC in Israel. © 2015 Wiley Periodicals, Inc.

  5. [Relation between physical activity, weight balance and breast cancer].

    Science.gov (United States)

    Maître, Carole

    2013-05-01

    Many epidemiologic studies, with a good methodology, support the evidence of the positive role of regular physical activity on primary and tertiary prevention of breast cancer on the risk of recurrence and mortality. This relation depends on the level of total energy expenditure by week, which helps balance weight on lifetime, an essential part of benefit. The beneficial effects of physical activity are linked to many interrelated additional mechanisms: in a short-term, contraction of skeletal muscles involves aerobic metabolism which utilizes glucose and amino acids like glutamine, improves insulin sensitivity and lowers plasma insulin; in a long-term, physical activity produces favorable changes in body composition, decreasing body fat and increasing lean mass. That is a key point to reduce the intake of energy substrates stimulating carcinogenesis, to improve insulin sensitivity, to change the ratio of leptin and adiponectin, to enhance cellular immunity and to block cellular pathways of cell proliferation and angiogenesis. Maintaining a healthy weight through regular physical activity well balanced with energy intake is it a goal for prevention of breast cancer. Copyright © 2013 Elsevier Masson SAS.

    Cancer mortality among 40,498 Hiroshima and Nagasaki residents was examined in relation to cigarette smoking habits and estimated atomic bomb radiation exposure. Relative risk models that are either multiplicative or additive in the two exposures (smoking radiation) were emphasized. Most analyses were directed toward all nonhematologic cancer, stomach cancer, lung cancer, or digestive cancer other than stomach, for which there were, respectively, 1,725, 658, 281, and 338 deaths in the follow-up period of this study. Persons heavily exposed to both cigarette smoke and radiation were found to have significantly lower cancer mortality than multiplcative relative risk models would suggest for all nonhematologic cancer, stomach cancer, and digestive cancer other than stomach. Surprisingly, the relative risk function appeared not only to be submultiplicative for these cancer sites, but to be subadditive as well. The lung cancer relative risk function could not be distinguished from either a multiplicative or an additive form. The number of deaths was sufficient to permit some more detailed study of all nonhematologic cancer mortality: Relative risk functions appeared to be consistent between males and females though a paucity of heavy smoking females limits the precision of this comparison.

    2010-09-01

    The treatment of primary breast cancer usually consists of surgery often followed by adjuvant therapy (radiotherapy, chemotherapy, hormonal treatment, etc.) to reduce the risk of recurrence. The cancer diagnosis and the treatments may have significant impact on the patients' quality of life. This thesis deals with scientific aspects and clinical results of a study aimed at assessing the impact of breast cancer (and its treatment) on the patients' quality of life. Studies such as this assessing the problems and symptoms experienced by the patients are often referred to as health-related quality of life (HRQL) research. HRQL research deals with subjective experiences and raises challenging, scientific questions. Therefore, much attention was directed towards methodological issues in this clinically motivated project. The study was a prospective, longitudinal, questionnaire-based investigation of women with newly diagnosed breast cancer registered in the Danish Breast Cancer Co-operative Group's DBCG 89 Program. The patients were sub-divided into low-risk and high-risk patients. High-risk patients were offered randomisation in one of three randomised adjuvant therapy trials involving chemotherapy, ovarian ablation, and endocrine therapy. After a literature study and interviews with breast cancer patients, a questionnaire was composed that included two widely used standard questionnaires (EORTC QLQ-C30 and Hospital Anxiety and Depression (HAD) Scale) and a DBCG 89 Questionnaire developed for this study. A total of 1,898 eligible patients were invited by post to participate in the study involving six assessments over a 2-year period, and 1,713 patients (90%) completed the first questionnaire. Furthermore, a questionnaire was sent to 872 women selected at random from the general population; 608 (70%) responded. The multi-item scales of the two standard questionnaires were analysed for so-called differential item functioning (DIF) in order to investigate whether the

    The study population of the S cohort (studies of underground miners of uranium and other substances as the source of information on long term effects of exposure to radon and its progeny) involve uranium miners, that started underground work at the Jachymov and Horni Slavkov mines in the period 1978-1959, and had worked at least for four years. A total 4320 men satisfied these criteria. During the decade up to 1990, follow-up of the cohort mainly relied on the national population registry. In order to improve the follow-u, a series of additional checks were conducted: in the files of the Czech and Slovak Pensions Offices, by local enquires, and by direct correspondence. These additional efforts resulted in an increase of more than 10% in the numbers of known men to have died or emigrated. An exceptional feature of the S study is the large number of measurements of radon concentrations made in each mine-shaft (mean number per year and shaft was 223 in the period 1949-1960). Each man`s annual exposures to radon progeny in terms of working levels were estimated combining measurement data with men`s employment details. The excess relative risk models were used in the form RR = c(1 + ERR(w,x)), where ERR is excess relative risk, w and x denote exposure history and modifying variable, and c is an intercept term that allows the mortality rate for `unexposed` cohort to differ from that in the general population. The increased mortality (O/E=1.58; where O is observed and E is expected cases among collected death cases in the cohort) in the cohort, generally, somewhat lower ratios than one reflect the non-industrial character of the region, with the exception of lung cancer in man. The differences in the O/E ratios for lung cancer among the separate communities indicate that even in the situation of generally lower mortality, the dependence of lung cancer mortality on radon exposure cannot be excluded. 3 tabs., 6 refs.

    Mechanisms are needed to remove from regulatory control those exposures or radiation sources that do not warrant concern. In this paper three such conceptual mechanisms are examined from their historical development to their current usage in the Interagency Basic Safety Standards. These concepts are exclusion, applied to exposures that are not amenable to control, exemption applied in advance on the basis of low risks to prevent practices or sources from entering the regulatory control system, and clearance, a similar concept but used to remove sources from the regulatory control system. The application of and interrelationships between these concepts, is described. (author)

    2006-08-01

    Full Text Available Abstract Background Self-tests are those where an individual can obtain a result without recourse to a health professional, by getting a result immediately or by sending a sample to a laboratory that returns the result directly. Self-tests can be diagnostic, for disease monitoring, or both. There are currently tests for more than 20 different conditions available to the UK public, and self-testing is marketed as a way of alerting people to serious health problems so they can seek medical help. Almost nothing is known about the extent to which people self-test for cancer or why they do this. Self-tests for cancer could alter perceptions of risk and health behaviour, cause psychological morbidity and have a significant impact on the demand for healthcare. This study aims to gain an understanding of the frequency of self-testing for cancer and characteristics of users. Methods Cross-sectional survey. Adults registered in participating general practices in the West Midlands Region, will be asked to complete a questionnaire that will collect socio-demographic information and basic data regarding previous and potential future use of self-test kits. The only exclusions will be people who the GP feels it would be inappropriate to send a questionnaire, for example because they are unable to give informed consent. Freepost envelopes will be included and non-responders will receive one reminder. Standardised prevalence rates will be estimated. Discussion Cancer related self-tests, currently available from pharmacies or over the Internet, include faecal occult blood tests (related to bowel cancer, prostate specific antigen tests (related to prostate cancer, breast cancer kits (self examination guide and haematuria tests (related to urinary tract cancers. The effect of an increase in self-testing for cancer is unknown but may be considerable: it may affect the delivery of population based screening programmes; empower patients or cause unnecessary anxiety

  19. Benefits of marriage on relative and conditional relative cancer survival differ between males and females in the USA.

    2017-10-01

    The purpose of the paper is to assess the influence of marital status on conditional relative survival of cancer according to sex. Analyses involved 779,978 males and 1,032,868 females diagnosed with 1 of 13 cancer types between 2000 and 2008, and followed through 2013. Data are from the Surveillance, Epidemiology, and End Results (SEER) Program. Regression models were adjusted for age, sex, race, and tumor stage. Five-year relative survival conditional on years already survived is higher among married patients with less lethal cancers (oral cavity and pharynx, colon and rectum, breast, urinary bladder, kidney and renal pelvis, melanoma of the skin, thyroid, lymphoma). For more lethal cancers, married patients have similar (liver, lung and bronchus, pancreas, leukemia) or poorer (brain and other nervous system) cancer survival. Separated/divorced or widowed patients have the lowest conditional relative survival rates. For most cancers, 5-year cancer relative survival rates conditional on time already survived through 5 years approach 70 to 90% of that for the general population. The beneficial effect of marriage on survival decreases with years already survived. Superior conditional relative survival rates in females decrease with time already survived and are less pronounced in married patients. Five-year relative survival rates improve with time already survived. The benefits of marriage on conditional relative survival are greater for less lethal cancers. Greater 5-year conditional relative survival rates in females narrow with time already survived and are less pronounced in married patients. Conditional relative survival rates of cancer can lead to more informed decisions and understanding regarding treatment and prognosis.

    The purpose of this study was to compare differences in health-related quality of life (HRQOL) between African-American female breast cancer survivors, African-American female survivors of other cancers, and African-American women with no history of cancer. Using data from the 2010 National Health Interview Survey (NHIS), the HRQOL of African-American women aged 35 years or older was compared by cancer status. Physical and mental health items from the Patient-Reported Outcomes Measurement Information System (PROMIS) global health scale were used to assess differences in HRQOL. For summary physical and mental health measures, no significant differences were found between breast cancer survivors and women with no history of cancer; survivors of other cancers reported poorer physical and mental health than did women with no history of cancer. Similar differences were found at the item level. When we examined the two African-American female cancer survivor groups, we found that cancer survivors whose cancer was being treated reported substantially poorer physical health and mental health than did those whose cancer was not being treated. Survivors who had private insurance and were cancer free reported better physical and mental health than did those who did not have private insurance and those who were not cancer free. Breast cancer survivors reported slightly better physical and mental health than did survivors of other cancers. Our findings highlight the need for public health agencies to adopt practices to improve the mental and physical health of African-American female survivors of cancer.

    This study aimed to (1) describe the Quality of Working Life (QWL) of cancer survivors and (2) explore associations between the QWL of cancer survivors and health- and work-related variables. Employed and self-employed cancer survivors were recruited through hospitals and patient organizations. They completed the Quality of Working Life Questionnaire for Cancer Survivors (QWLQ-CS) and health- and work-related variables in this cross-sectional study. The QWL scores of cancer survivors were described, and associations between QWL and health- and work-related variables were assessed. The QWLQ-CS was completed by 302 cancer survivors (28% male) with a mean age of 52 ± 8 years. They were diagnosed between 0 and 10 years ago with various types of cancer, such as breast cancers, gastrointestinal cancers, urological cancers, and haematological cancers. The QWL mean score of cancer survivors was 75 ± 12 (0-100). Cancer survivors had statistically significant lower QWL scores when they had been treated with chemotherapy or when they reported co-morbidity (p ≤ 0.05). Cancer survivors without managerial positions, with low incomes or physically demanding work, and who worked a proportion of their contract hours had statistically significantly lower QWL scores (p ≤ 0.05). This study described the QWL of cancer survivors and associations between QWL and health- and work-related variables. Based on these variables, it is possible to indicate groups of cancer survivors who need more attention and support regarding QWL and work continuation.

    Biases in processing information related to sources of stress have widely been demonstrated with the use of Stroop emotional color word tasks. One study reported such biases among women with histories of breast cancer in a first-degree relative (FH+) who were given a Stroop cancer word task. This study aimed to replicate and extend these findings with a computerized version of the task. Response latencies and errors were recorded during administration of the task to FH+ and FH- women. A cancer list and 5 comparison lists were administered. Results indicated that FH+ women exhibited longer response latencies for cancer words than did FH- women (p Stroop cancer word task.

    Fatigue is a common symptom in cancer patients that can persist beyond the curative treatment phase. Some evidence has been reported for interventions for fatigue during active treatment. However, to date, there is no systematic review on psychological interventions for fatigue after the completion of curative treatment for cancer. This is a protocol for a systematic review that aims to evaluate the effectiveness of psychological interventions for cancer-related fatigue in post-treatment cancer survivors. This systematic review protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) database. We will search the Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library), PubMed, MEDLINE, EMBASE, CINAHL, PsycINFO, and relevant sources of grey literature. Randomised controlled trials (RCTs) which have evaluated psychological interventions in adult cancer patients after the completion of treatment, with fatigue as an outcome measure, will be included. Two review authors will independently extract data from the selected studies and assess the methodological quality using the Cochrane Collaboration Risk of Bias Tool. Most existing evidence on cancer-related fatigue is from those in active cancer treatment. This systematic review and meta-analysis will build upon previous evaluations of psychological interventions in people during and after cancer treatment. With the growing need for stage-specific research in cancer, this review seeks to highlight a gap in current practice and to strengthen the evidence base of randomised controlled trials in the area.

Because many prostate cancer-related symptoms and side-effects are potentially modifiable, we investigated associations between symptoms and psychological wellbeing among prostate cancer survivors. Postal questionnaires were distributed to men diagnosed with prostate cancer 2-18 years previously identified through cancer registries. General and prostate cancer-specific symptoms were assessed using the EORTC QLQ-C30 and QLQ-PR25, with higher symptom scores indicating more/worse symptomatology. Psychological wellbeing was assessed by the DASS-21. Associations between symptoms and each outcome were investigated using multivariate logistic regression, controlling for socio-demographic and clinical factors. A total 3348 men participated (response rate = 54%). Seventeen percent (95%CI 15.2%-17.9%), 16% (95%CI 15.1%-17.8%) and 11% (95%CI 9.5%-11.8%) of survivors scored in the range for depression, anxiety and distress on the DASS scales, respectively. In multivariate models, risk of depression on the DASS scale was significantly higher in men with higher urinary and androgen deprivation therapy (ADT)-related symptoms, and higher scores for fatigue, insomnia and financial difficulties. Risk of anxiety on the DASS scale was higher in men with higher scores for urinary, bowel and ADT-related symptoms and fatigue, dyspnoea and financial difficulties. Risk of distress on the DASS scale was positively associated with urinary, bowel and ADT-related symptoms, fatigue, insomnia and financial difficulties. Cancer-related symptoms significantly predict psychological wellbeing among prostate cancer survivors. Greater use of interventions and medications and to alleviate symptoms might improve psychological wellbeing of prostate cancer survivors. Copyright © 2015 John Wiley & Sons, Ltd.

    Martin Cernvall

    Full Text Available To investigate whether posttraumatic stress symptoms (PTSS are related to attentional bias towards cancer-related stimuli among parents of children recently diagnosed with cancer.Sixty-two parents completed questionnaires measuring PTSS, depression, and anxiety and the emotional Stroop task via the Internet. The emotional Stroop task included cancer-related words, cardiovascular disease-related words, and neutral words.Participants were split in two groups based on the median of PTSS: High-PTSS and Low-PTSS. There was a significant interaction between word-type and group and a planned contrast test of this interaction indicated that the High-PTSS group had longer response latencies on cancer-related words compared to the other word-type and group combinations.Findings suggest that PTSS are related to attentional bias towards cancer-related stimuli among parents of children recently diagnosed with cancer. Implications of this finding for the understanding of PTSS in this population, future research, and clinical practice are discussed.

    2010-03-01

    The research on the determinants of mental health among refugees has been largely limited to traumatic events, but recent work has indicated that the daily hassles of living in refugee camps also play a large role. Using hierarchical linear modelling to account for refugees nested within camp blocks, this exploratory study attempted to model stress surrounding safety and acquiring basic needs and functional impairment among refugees from Darfur living in Chad, using individual-level demographics (e.g., gender, age, presence of a debilitating injury), structural factors (e.g., distance from block to distribution centre), and social ecological variables (e.g., percentage of single women within a block). We found that stress concerning safety concerns, daily hassles, and functional impairment were associated with several individual-level demographic factors (e.g., gender), but also with interactions between block-level and individual-level factors as well (e.g., injury and distance to distribution centre). Findings are discussed in terms of monitoring and evaluation of refugee services.

    Background Cancer is one of the top five most costly diseases in the United States and leads to substantial work loss. Nevertheless, limited state-level estimates of cancer absenteeism costs have been published. Methods In analyses of data from the 2004–2008 Medical Expenditure Panel Survey, the 2004 National Nursing Home Survey, the U.S. Census Bureau for 2008, and the 2009 Current Population Survey, we used regression modeling to estimate annual state-level absenteeism costs attributable to cancer from 2004 to 2008. Results We estimated that the state-level median number of days of absenteeism per year among employed cancer patients was 6.1 days and that annual state-level cancer absenteeism costs ranged from $14.9 million to $915.9 million (median = $115.9 million) across states in 2010 dollars. Absenteeism costs are approximately 6.5% of the costs of premature cancer mortality. Conclusions The results from this study suggest that lost productivity attributable to cancer is a substantial cost to employees and employers and contributes to estimates of the overall impact of cancer in a state population.

    1984-01-01

    A continuation of the series by Mancuso, Stewart, and Kneale (MSK) on studies of cancer risks for radiation workers at Hanford is presented. It concentrates on the statistical problems posed by the need to estimate and control for job related mortality risks when there are several changes of occupation and no certainty about how different occupations are related to two socioeconomic factors which have strong health associations-namely, education and income. The final conclusion is that for tissues which are sensitive to cancer induced by radiation there is a risk of cancer for Hanford exposures whose dose response is curvilinear with long latency and increasing effect with increasing exposure age.

  20. Healing environments in cancer treatment and care. Relations of space and practice in hematological cancer treatment.

    2013-02-01

    Given the growing attention to the importance of design in shaping healing hospital environments this study extends the understanding of healing environments, beyond causal links between environmental exposure and health outcome by elucidating how environments and practices interrelate. The study was conducted as an ethnographic fieldwork from March 2011 to September 2011 at the Department of Haematology at Odense University Hospital, Denmark, systematically using participant observation and interviews as research strategies. It included 20 patients, four of who were followed closely over an extended time period. Through thematic analysis five key concepts emerged about the social dynamics of hospital environments: practices of self; creating personal space; social recognition; negotiating space; and ambiguity of space and care. Through these concepts, the study demonstrates how the hospital environment is a flow of relations between space and practice that changes and challenges a structural idea of design and healing. Patients' sense of healing changes with the experience of progression in treatment and the capacity of the hospital space to incite an experience of homeliness and care. Furthermore, cancer patients continuously challenge the use and limits of space by individual objects and practices of privacy and home. Healing environments are complex relations between practices, space and care, where recognition of the individual patient's needs, values and experiences is key to developing the environment to support the patient quality of life. The present study holds implications for practice to inform design of future hospital environments for cancer treatment. The study points to the importance for being attentive to the need for flexible spaces in hospitals that recognize the dynamics of healing, by providing individualized care, relating to the particular and changing needs of patients supporting their potential and their challenged condition with the best

  3. Relative risks of radiation-associated cancer: comparison of second cancer in therapeutically irradiated populations with the Japanese atomic bomb survivors

    1999-01-01

    In this paper the radiation-associated relative risks of second primary cancer incidence in groups treated for first primary cancer by radiotherapy are compared with radiation-associated relative risk estimates in the Japanese atomic bomb survivor cancer incidence data. For four cancer sites, namely lung cancer, bone cancer, ovarian cancer and leukaemia, the relative risks in the comparable (age at exposure, time since exposure, sex matched) subsets of the Japanese data are significantly greater than those in the majority of second cancer studies. Even when the differences between the relative risks in the Japanese atomic bomb survivors and the medical series do not approach conventional levels of statistical significance, relative risks tend to be higher in the Japanese data than in the second cancer studies. At least for leukaemia, the discrepancy between the Japanese and second cancer risks can be largely explained by cell- sterilisation effects. There are few indications of modification of radiation-associated second cancer relative risk among those treated with adjuvant chemotherapy, nor are there strong indications of modification of radiation- associated relative risk by heritable genetic factors. If anything, there is evidence that second cancer relative excess risks are lower among those patients with cancer-prone disorders than among non-susceptible patients. However, the higher underlying cancer risk in some of these medically exposed populations should also be considered, in particular for those with cancer-prone conditions, so that the absolute excess risk is sometimes higher than in the Japanese data.

  4. Guide related to the sanitation of structures in basic nuclear installations. Guide Nr 14, Release of 30 August 2016

    International Nuclear Information System (INIS)

    2016-01-01

    After having indicated the relevant regulatory texts and guides, this guide defines ASN recommendations for the sanitation methodology to be applied when, for example, some premises of buildings are subject to a change of use, are to be demolished, or are to be cleaned after events which occurred during operation. Some definitions are first specified: sanitation objective, verification criterion, singular point, structure, area. After having rather briefly recalled the general doctrine adopted for waste management in basic nuclear installations, the guide states the ASN doctrine regarding structure sanitation by presenting various concepts: complete sanitation, extensive sanitation, and sanitation during operation. It presents principles of sanitation of constituent structures of an area which may produce nuclear wastes (three defence lines are distinguished: thoughtful definition of sanitation modalities, confirmation of the conventional character of structures after sanitation, radiological control of any waste). Administrative procedures are then addressed: before sanitation works, during sanitation works, and after sanitation works (depending on the compatibility of structure radiological condition). Quality assurance requirements are evoked. The guide then describes the modalities of definition of the three different defence lines, and indicates requirements regarding sanitation works (control of contamination dissemination, conditions of intervention, case of civil engineering metallic structures, control of remaining structure elements). A peculiar case is briefly addressed: sanitation of removable structure elements. Appendices indicate the main themes addressed by the sanitation methodology, and by the sanitation assessment. A model sheet is proposed to specify the downgrading of a premise which was previously classified as an area of possible production of nuclear wastes

The population from which samples were taken are football referees of the Sarajevo Canton, 90 of them, age span from 18- 45 years of age and who have met the criteria for getting a license to be referees in football matches in the next season at all levels of competition in Bosnia and Herzegovina. The sample of variables in this research covers areas of basic motorics (18, theoretic knowledge laws of the games (17 and the estimate of success in refereeing in football games (7 variables. The results of the final analysis show that the whole system of variables which in this research represent basic physical capabilities and the knowledge Laws of the game by the football referees of the Sarajevo Canton has a statistical connection with the system of variables which in this research makes the success of refereeing of football referees. Since football is an activity that has almost the most complexity (referees are a part of football, we can say that the selected system of variables has a relatively good connection for success and that these variables are very important in order for one referee to perform his task as good as possible at one match.. Of course during the training process attention should be given on the development of all basic physical capabilities, and not only one dimension of the physical area because in general we have to be physically and cognitively be present in order to finish the game at a high rhythm but making mistakes the least as possible

    Tumors are known to be heterogeneous containing a dynamic mixture of phenotypically and functionally different tumor cells. The two concepts attempting to explain the origin of intratumor heterogeneity are the cancer stem cell hypothesis and the clonal evolution model. The stochastic model argues that tumors are biologically homogenous and all cancer cells within the tumor have equal ability to propagate the tumor growth depending on continuing mutations and selective pressure. By contrast, the stem cells model suggests that cancer heterogeneity is due to the hierarchy that originates from a small population of cancer stem cells (CSCs) which are biologically distinct from the bulk tumor and possesses self-renewal, tumorigenic and multilineage potential. Although these two hypotheses have been discussed for a long time as mutually exclusive explanations of tumor heterogeneity, they are easily reconciled serving as a driving force of cancer evolution and diversity. Recent discovery of the cancer cell plasticity and heterogeneity makes the CSC population a moving target that could be hard to track and eradicate. Understanding the signaling mechanisms regulating CSCs during the course of cancer treatment can be indispensable for the optimization of current treatment strategies

    An attempt has been made to replace the principle of relativity with the principle of covariance. This amounts to modification of the theory of relativity based on the two postulates (i) the principle of covariance and (ii) the light principle. Some of the fundamental results and the laws of relativistic mechanics, electromagnetodynamics and quantum mechanics are re-examined. The principle of invariance is questioned. (A.K.)

    Full Text Available Managing emotional distress triggers different coping strategies for coping with stress in cancer patients. Effective coping affects health – related quality of life and psychosocial adaptation. This study was performed to determine coping strategies, and their connectedness to emotional distress (anxiety and depression and health – related quality of life in cancer patients. Study was carried out on 70 cancer patients, in inpatient and outpatient setting. Depressive symptoms were measured with Beck Depression Inventory BDI-SH, anxiety with State Trait Anxiety Inventory STAI-1, coping strategies with Coping Response Inventory CRI and health – related quality of life with Quality of Life Questionnaire QOLQ- 30. A negative, statistically important relationship was found between active strategies, emotional distress and quality of life. Recognition of emotional distress and ways of coping in cancer patients are important for quality of health care.

    Tumor necrosis factor-α (TNF-α) is an important cytokine associated with tumor regression and increased survival time for cancer patients. Research evidence relates immune factors (e.g., natural killer (NK) cell counts, NK cell lysis, lymphocyte profile, and lymphocyte proliferation) to the frequency and quality of social relations among cancer patients. We hypothesized that disruptions in social relations would be associated with lower TNF-α responses, and conversely, that reports of positive changes in social relations correlate with stronger responses. A prospective design measured changes in social activity and relationship satisfaction with a partner in 44 breast cancer patients at the time of cancer diagnosis, and initial surgery and 12 months later. Results indicated that patients reporting increased social activities or satisfaction exhibited stronger stimulated TNF-α responses. This is the first study to link changes in patient social relations with a cancer-relevant immune variable. PMID:15890493

    The purpose of this study was to analyze nursing-related content in middle, and high school textbooks under the National Common Basic Curriculum in Korea. Nursing-related content from 43 middle school textbooks and 13 high school textbooks was analyzed. There were 28 items of nursing-related content in the selected textbooks. Among them, 13 items were in the 'nursing activity' area, 6 items were in the 'nurse as an occupation' area, 2 items were in the 'major and career choice' area, 6 items were 'just one word' and 1 item in 'others'. The main nursing related content which portrayed in the middle and high school textbooks were caring for patients (7 items accounting for 46.5%), nurses working in hospitals (6 items accounting for 21.4%). In terms of gender perspective, female nurses (15 items accounting for 53.6%) were most prevalent.

    Since meat may be involved in the etiology of colorectal cancer, associations between meat-related compounds were examined to elucidate underlying mechanisms in a population-based case-control study. Participants (989 cases/1,033 healthy controls) completed a food frequency questionnaire with a meat-specific module. Multivariable logistic regression was used to examine associations between meat variables and colorectal cancer; polytomous logistic regression was used for subsite-specific analyses. The following significant positive associations were observed for meat-related compounds: 2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline (DiMeIQx) and colorectal, distal colon, and rectal tumors; 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) and colorectal and colon cancer tumors; nitrites/nitrates and proximal colon cancer; 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) and rectal cancer; and benzo[a]pyrene and rectal cancer (P-trends cancer and pan-fried red meat and colorectal cancer were found (P-trends cancer; and well-done/charred poultry and colorectal, colon, and proximal colon tumors (P-trends nitrates may be involved in colorectal cancer etiology.

    The purpose of this article is to examine the health beliefs and literacy about breast cancer and their relationship with breast cancer screening among American Indian (AI) women. Using the Health Belief Model (HBM) and hierarchical logistic regression with data from a sample of 286 AI female adults residing in the Northern Plains, we found that greater awareness of breast cancer screening was linked to breast cancer screening practices. However, perceived barriers, one of the HBM constructs, prevented such screening practices. This study suggested that culturally relevant HBM factors should be targeted when developing culturally sensitive breast cancer prevention efforts.

    Objective: To introduce the general international method for estimation of lifetime risk of developed cancer, and to estimate the lifetime risk baseline values of several kinds of cancers related to radiation exposures in China. Methods: The risk estimation was based on the data from Chinese Cancer Registry Annual Report (2010) and China Population and Employment Statistics Yearbook (2009), and made according to the method previously published by National Cancer Institute (NCI) in USA. Results: The lifetime risk of all cancer in China in 2007 was estimated to be 27.77%, that of lung cancer 5.96%, that of breast cancer for female 3.34%, that of all leukemia 0.14%, that of thyroid cancer 0.37%. The lifetime risks of all cancer were estimated to be 32.74% for males and 24.73% for females, and that was 36.47% for urban residents and 26.79% for rural people. Conclusions: The lifetime risk of all cancer for males in 2007 was about 1.25 times as much as that for females. The value of all cancer for urban residents was about 1.35 times as much as that for rural residents. The lifetime risk of developed cancers in 2007 in China is lower than that in the developed countries,such as Japan. (authors)

    A nested, matched case-control study was conducted to assess the relationship between serum levels of copper and the subsequent risk of cancer. One hundred thirty-three cases of cancer were identified during 1974-1984 among 5000 members of a northwest Washington State employee cohort from whom serum specimens had been previously obtained and stored. Two hundred forty-one controls were selected at random from the cohort and were matched to the cases on the basis of age, sex, race, and date of blood draw. Serum copper levels were measured by atomic absorption spectrometry. Risk of a subsequent diagnosis of cancer was positively associated with serum copper levels, but only among those cases diagnosed within 4 years of the time the serum specimens were collected. Among cases diagnosed more than 4 years after specimen collection, there was no consistent association between serum copper levels and risk. Adjustment for age, sex, race, occupational status, cigarette smoking, family history of cancer, alcohol consumption, and, among females, use of exogenous hormones had no appreciable effect on these relationships. The findings suggest that the presence of cancer may increase serum copper levels several years prior to its diagnosis. They are less supportive of the hypothesis that serum copper levels affect cancer risk.

    Purpose of this systematic literature review was to identify current knowledge about employment in cancer survivors. Sixty-four studies met inclusion criteria that were original papers published between 01/2000 and 11/2009. Overall, 63.5% of cancer survivors (range 24-94%) returned to work. The mean duration of absence from work was 151 days. Factors significantly associated with a greater likelihood of being employed or return to work were perceived employer accommodation, flexible working arrangements, counseling, training and rehabilitation services, younger age and cancer sites of younger individuals, higher levels of education, male gender, less physical symptoms, lower length of sick leave and continuity of care. Cancer survivors had a significantly increased risk for unemployment, early retirement and were less likely to be re-employed. Between 26% and 53% of cancer survivors lost their job or quit working over a 72-month period post diagnosis. Between 23% and 75% of patients who lost their job were re-employed. A high proportion of patients experienced at least temporary changes in work schedules, work hours, wages and a decline in work ability compared to non-cancer groups.

    Return to work after treatment completion is important for both cancer survivors and society. Financial distress is one of the factors that may influence the return to work in cancer survivors. However, this relationship has not been well investigated. This study aimed to determine the rate of return to work and its relation to financial distress among Iranian cancer survivors. This descriptive-correlational study was undertaken among 165 cancer survivors who completed their initial treatments and had no signs of active cancer. The Return to Work questionnaire and Financial Distress/Financial Well-Being Scale were used for data collection. Data were analyzed using SPSS statistical software. After initial treatments, 120 cancer survivors (72%) had returned to work, of which 50 patients (42%) had returned to full-time work and 70 (58%) reduced their work hours and returned to part-time work. Cancer survivors also reported high levels of financial distress. In addition, the financial distress was lower among patients who had returned completely to work, in comparison to patients who had quit working for cancer-related reasons (p=0.001) or returned to work as part-time workers (p=0.001). The findings showed that a high percent of Iranian cancer survivors had not returned to their jobs or considerably reduced working hours after treatment completion. Accordingly, due to high levels of financial distress experienced by participants and its relation to return to work, designing rehabilitation programs to facilitate cancer survivor return to work should be considered.

  5. Oxidative DNA as related to cancer and aging

    1987-01-01

    DNA damage in man can result from a variety of endogenous processes. Of particular importance as endogenous processes may be metabolic pathways that generate oxygen radicals and other reactive oxygen species. Oxygen radicals have been shown to produce DNA base damage and strand breaks. Two products that are formed in DNA in vitro by chemical oxidation or ionizing radiation (and oxidative mutagen) are thymine glycol and hydroxymethyl-uracil, both oxidation products of thymine. Specific mammalian DNA repair systems are known to excise these lesions from DNA in vitro. The authors' laboratory has recently reported the identification, in both human and rat urine, of thymine glycol, thymidine glycol, and hydroxymethyluracil. They now have considerable evidence that these products are derived from the repair of oxidized DNA. The total output of these three compounds represents the formation of about 1,000 oxidized thymine residues per cell per day in man. Since these products are only three of a considerable number of types of oxidative DNA damage products described by radiobiologists, there are likely to be several thousand oxidative DNA hits per cell per day in man. Rats, which have a higher specific metabolic rate and a shorter life span, excrete about 15 times more thymine glycol, thymidine glycol, and hydroxymethyluracil per kilogram body weight. The authors also describe new methods for measuring the levels, which are considerable, of hydrogen peroxide and lipid hydroperoxides in normal plasma and tissues. These non-invasive assays of DNA and other oxidation products may allow the direct testing of current theories that relate oxidative metabolism to the processes of cancer and aging in man

    Full Text Available As membrane-bound structures that could be shedded by a parental cell, and fuse with others after shedding, and then release its contents, extracellular vesicles (EVs are considered as an indispensable part of intercellular communication system. The EV contents might be all kinds of bioactive molecules including non-coding RNAs (ncRNAs, a large and complex group of RNAs with various subtypes that function to regulate biological events but classically do not code for proteins. In this review we covered the recently published works that validated the underlying molecular mechanisms regulating EV-associated ncRNAs' biogenesis, signaling, and particularly the systemic bio-effects related mostly to any stage of cancer progression, and the clinical potential of ncRNA-carrying EVs as diagnostic biomarkers and drug-delivery system that is being engineered for better loading and targeting capacity. Our views on the future direction of basic research and applications of EVs containing ncRNAs have also been shared.

    The purpose of this master's thesis is to utilize basic data in order to improve the quality of life of cancer patients who received radiation therapy after analysing related factors that influence patient's quality of life and obtaining information about physical, mental problems of patients. By using a structured questionnaire about various characteristics and forms of support, I carried out a survey targeting 107 patients that experienced radiation therapy at a university hospital in the Daejeon metropolitan area from July 15 to August 15, 2010 and analysed the factors influencing quality of life. In case of pain due to disease, 65.15 and painless 81.87 showed a high grade quality of life. As body weight decreases, the quality of life become lower. When the grade of quality of life according to economic characteristics was compared, all items except treatment period showed a difference (P=0.000). When the score of social support, family support, medical support and self-esteem was low, the mark of quality of life showed respectively 61.71, 68.77, 71.31, and 69.39 on the basis of 128 points. When the score of support form was high, the mark of quality of life showed 90.47, 83.29, 90.40, and 90.36 (P<0.05). When analyzing the correlation between social support, family support, medical support and self-esteem and the degree of quality of life, social support was 0.768, family support 0.596, medical support 0.434, self-esteem 0.516. They indicated the correlation of meaningful quantity statistically (P<0.01). The factors that improved the quality of life were married state, having a job and painless status. As monthly income increases, the quality of life was also much improved (P<0.05). Among the factors related to quality of life, social support and medical support and higher self-esteem scores of the quality of life score increased 0.979 point, 0.508 points and 1.667 point, respectively.

    Previous studies have suggested that negative beliefs about cancer may impair patients' psychological well-being, but only a few of these studies focused on specific psychological symptoms, and many were cross-sectional. The aim of this study was to investigate longitudinally the relationship of cancer-related cognitions with the severity, incidence, and persistence of anxiety, fear of cancer recurrence, depression, and insomnia symptoms during an 18-month period. Patients scheduled to undergo surgery for cancer (N = 962) completed a questionnaire assessing cancer-related cognitions at baseline (T1), the Hospital Anxiety and Depression Scale, the severity subscale of the Fear of Cancer Recurrence Inventory, and the Insomnia Severity Index at baseline (T1) and 2 (T2), 6 (T3), 10 (T4), 14 (T5), and 18 (T6) months later. Group × time factorial analyses using mixed models revealed that participants endorsing more negative cancer-related cognitions consistently reported more severe symptoms throughout the 18-month period. Logistic regression analyses suggested that endorsing more negative cancer-related cognitions at T1 significantly increased incidence and persistence rates of clinical levels of psychological symptoms. These findings suggest that the endorsement of negative cancer-related beliefs at the perioperative period influences the longitudinal evolution of anxiety, fear of cancer recurrence, depression, and insomnia symptoms in the following months. These results highlight the relevance of using cognitive restructuring early during the cancer care trajectory to potentially revise erroneous beliefs about cancer and prevent the incidence and persistence of psychological disturbances over time.

    2012-01-01

    Full Text Available A cancer diagnosis elicits strong psychophysiological reactions that characterize stress. Stress is experienced by all patients but is usually not discussed during patient-healthcare professional interaction; thus underdiagnosed, very few are referred to support services. The prevalence of CAM use in patients with history of cancer is growing. The purpose of the paper is to review the aspects of cancer-related stress and interventions of commonly used complementary and alternative techniques/products for amelioration of cancer-related stress. Feasibility of intervention of several CAM techniques and products commonly used by cancer patients and survivors has been established in some cancer populations. Efficacy of some CAM techniques and products in reducing stress has been documented as well as stress-related symptoms in patients with cancer such as mindfulness-based stress reduction, yoga, Tai Chi Chuan, acupuncture, energy-based techniques, and physical activity. Much of the research limitations include small study samples and variety of intervention length and content. Efficacy and safety of many CAM techniques and some herbs and vitamin B and D supplements need to be confirmed in further studies using scientific methodology. Several complementary and alternative medicine therapies could be integrated into standard cancer care to ameliorate cancer-related stress.

    To investigate the employment status of lung cancer survivors and the work-related problems they face. Although the number of lung cancer survivors is increasing, little is known about their employment and work-related issues. We enrolled 830 lung cancer survivors 12 months after lung cancer curative surgery (median time after diagnosis, 4.11 years) and 1000 volunteers from the general population. All participants completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, Core 30-item and a questionnaire that included items relating to their jobs. We used logistic regression analysis to identify independent predictors of unemployment. The employment rate of lung cancer survivors decreased from 68.6% at the time of diagnosis to 38.8% after treatment, which was significantly lower than the employment rate of the general population (63.5%; adjusted odds ratio = 2.31, 95% confidence interval: 1.66-3.22). The posttreatment unemployment rate was higher for women than for men. Among survivors, employment was inversely associated with older age, household income, number of comorbidities, and poor social functioning. Fatigue (78.6%) was the most common work-related problem reported by survivors. Lung cancer survivors experienced more difficulties in employment than did the general population. Age, monthly household income, number of comorbidities, and social functioning appear to be important factors influencing employment status. These findings suggest that lung cancer survivors need support to cope with the financial impact of cancer.

    Most measures of the cancer burden take a public health perspective. Cancer also has a significant economic impact on society. To assess this economic burden, we estimated years of potential productive life lost (YPPLL) and costs of lost productivity due to premature cancer-related mortality in Ireland. All cancers combined and the 10 sites accounting for most deaths in men and in women were considered. To compute YPPLL, deaths in 5-year age-bands between 15 and 64 years were multiplied by average working-life expectancy. Valuation of costs, using the human capital approach, involved multiplying YPPLL by age-and-gender specific gross wages, and adjusting for unemployment and workforce participation. Sensitivity analyses were conducted around retirement age and wage growth, labour force participation, employment and discount rates, and to explore the impact of including household production and caring costs. Costs were expressed in €2009. Total YPPLL was lower in men than women (men = 10,873; women = 12,119). Premature cancer-related mortality costs were higher in men (men: total cost = €332 million, cost/death = €290,172, cost/YPPLL = €30,558; women: total cost = €177 million, cost/death = €159,959, cost/YPPLL = €14,628). Lung cancer had the highest premature mortality cost (€84.0 million; 16.5% of total costs), followed by cancers of the colorectum (€49.6 million; 9.7%), breast (€49.4 million; 9.7%) and brain & CNS (€42.4 million: 8.3%). The total economic cost of premature cancer-related mortality in Ireland amounted to €509.5 million or 0.3% of gross domestic product. An increase of one year in the retirement age increased the total all-cancer premature mortality cost by 9.9% for men and 5.9% for women. The inclusion of household production and caring costs increased the total cost to €945.7 million. Lost productivity costs due to cancer-related premature mortality are significant. The higher premature mortality cost in males than

    Calculating accurate estimates of cancer survival is important for various analyses of cancer patient care and prognosis. Current US survival rates are estimated based on data from the National Cancer Institute's (NCI's) Surveillance, Epidemiology, and End RESULTS (SEER) program, covering approximately 28 percent of the US population. The National Program of Cancer Registries (NPCR) covers about 96 percent of the US population. Using a population-based database with greater US population coverage to calculate survival rates at the national, state, and regional levels can further enhance the effective monitoring of cancer patient care and prognosis in the United States. The first step is to establish the coding completeness and coding quality of the NPCR data needed for calculating survival rates and conducting related validation analyses. Using data from the NPCR-Cancer Surveillance System (CSS) from 1995 through 2008, we assessed coding completeness and quality on 26 data elements that are needed to calculate cancer relative survival estimates and conduct related analyses. Data elements evaluated consisted of demographic, follow-up, prognostic, and cancer identification variables. Analyses were performed showing trends of these variables by diagnostic year, state of residence at diagnosis, and cancer site. Mean overall percent coding completeness by each NPCR central cancer registry averaged across all data elements and diagnosis years ranged from 92.3 percent to 100 percent. RESULTS showing the mean percent coding completeness for the relative survival-related variables in NPCR data are presented. All data elements but 1 have a mean coding completeness greater than 90 percent as was the mean completeness by data item group type. Statistically significant differences in coding completeness were found in the ICD revision number, cause of death, vital status, and date of last contact variables when comparing diagnosis years. The majority of data items had a coding

    Some basic explanations are given of the principles underlying the nuclear fuel cycle, starting with the physics of atomic and nuclear structure and continuing with nuclear energy and reactors, fuel and waste management and finally a discussion of economics and the future. An important aspect of the fuel cycle concerns the possibility of ''closing the back end'' i.e. reprocessing the waste or unused fuel in order to re-use it in reactors of various kinds. The alternative, the ''oncethrough'' cycle, discards the discharged fuel completely. An interim measure involves the prolonged storage of highly radioactive waste fuel. (UK)

    To determine mortality associated with a new cancer diagnosis in an urban, predominantly African-American, HIV-infected population. Retrospective cohort study. All HIV-infected patients diagnosed with cancer between 1 January 2000 and 30 June 2010 were reviewed. Mortality was examined using Kaplan-Meier estimates and Cox proportional hazards models. There were 470 cases of cancer among 447 patients. Patients were predominantly African-American (85%) and male (79%). Non-AIDS-defining cancers (NADCs, 69%) were more common than AIDS-defining cancers (ADCs, 31%). Cumulative cancer incidence increased significantly over the study period. The majority (55.9%) was taking antiretroviral therapy (ART) at cancer diagnosis or started afterward (26.9%); 17.2% never received ART. Stage 3 or 4 cancer was diagnosed in 67%. There were 226 deaths during 1096 person years of follow-up, yielding an overall mortality rate of 206 per 1000 person years. The cumulative mortality rate at 30 days, 1 year, and 2 years was 6.5, 32.2, and 41.4%, respectively. Mortality was similar between patients on ART whether they started before or after the cancer diagnosis but was higher in patients who never received ART. In patients with a known cause of death, 68% were related to progression of the underlying cancer. In a large cohort of urban, predominantly African-American patients with HIV and cancer, many patients presented with late-stage cancer. There was substantial 30-day and 2-year mortality, although ART had a significant mortality benefit. Deaths were most often caused by progression of cancer and not from another HIV-related or AIDS-related event.

    Diseases at the molecular level are complex and patient dependent, necessitating development of strategies that enable precision treatment to optimize clinical outcomes. Organoid technology has recently been shown to have the potential to recapitulate the in vivo characteristics of the original individual's tissue in a three-dimensional in vitro culture system. Here, we present a quantitative mass-spectrometry-based proteomic analysis and a comparative transcriptomic analysis of human colorectal tumor and healthy organoids derived, in parallel, from seven patients. Although gene and protein signatures can be derived to distinguish the tumor organoid population from healthy organoids, our data clearly reveal that each patient possesses a distinct organoid signature at the proteomic level. We demonstrate that a personalized patient-specific organoid proteome profile can be related to the diagnosis of a patient and with future development contribute to the generation of personalized therapies.

    Full Text Available Ovarian Cancer represents the most fatal type of gynecological malignancies. A number of processes are involved in the pathogenesis of ovarian cancer, especially within the tumor microenvironment. Angiogenesis represents a hallmark phenomenon in cancer, and it is responsible for tumor spread and metastasis in ovarian cancer, among other tumor types, as it leads to new blood vessel formation. In recent years angiogenesis has been given considerable attention in order to identify targets for developing effective anti-tumor therapies. Growth factors have been identified to play key roles in driving angiogenesis and, thus, the formation of new blood vessels that assist in “feeding” cancer. Such molecules include the vascular endothelial growth factor (VEGF, the platelet derived growth factor (PDGF, the fibroblast growth factor (FGF, and the angiopoietin/Tie2 receptor complex. These proteins are key players in complex molecular pathways within the tumor cell and they have been in the spotlight of the development of anti-angiogenic molecules that may act as stand-alone therapeutics, or in concert with standard treatment regimes such as chemotherapy. The pathways involved in angiogenesis and molecules that have been developed in order to combat angiogenesis are described in this paper.

    2009-01-01

    The project objective is to study structure-property relations in solid solutions of nitrides and oxides with surrogate elements to simulate the behavior of fuels of inert matrix fuels of interest to the Advanced Fuel Cycle Initiative (AFCI), with emphasis in zirconium-based materials. Work with actual fuels will be carried out in parallel in collaboration with Los Alamos National Laboratory (LANL). Three key aspects will be explored: microstructure characterization through measurement of global texture evolution and local crystallographic variations using Electron Backscattering Diffraction (EBSD); determination of mechanical properties, including fracture toughness, quasi-static compression strength, and hardness, as functions of load and temperature, and, finally, development of structure-property relations to describe mechanical behavior of the fuels based on experimental data. Materials tested will be characterized to identify the mechanisms of deformation and fracture and their relationship to microstructure and its evolution. New aspects of this research are the inclusion of crystallographic information into the evaluation of fuel performance and the incorporation of statistical variations of microstructural variables into simplified models of mechanical behavior of fuels that account explicitly for these variations. The work is expected to provide insight into processing conditions leading to better fuel performance and structural reliability during manufacturing and service, as well as providing a simplified testing model for future fuel production

    Full Text Available Introduction: Family history of colorectal cancer has been shown to be related to the risk of developing colorectal cancer. This risk depends on the number of affected relatives and the age at diagnosis. In this study we aimed to estimate the frequency of a positive family history of colorectal cancer in a random sample from Tehran population. Materials and Methods: This study was a community-based cross-sectional survey conducted from May 2006 to December 2007 in Tehran province, Iran. A total of 5,500 peoples (age≥20 years drawn up randomly by random sampling according to postal codes and invited to participate in the study. All participants completed a detailed health data registry form on family history status of colorectal cancer. Results: The mean age of men with a positive family history was significantly different from men with negative family history. There was no significant difference between mean age of women responders with or without positive family history. Among all participants (n=5,500, 162 responders (2.9% had a history of colorectal cancer. Of 162, 67 responders (1.22% had one and 4(0.07% had two or more first-degree relative with colorectal cancer. Of 5,500 participants, 18 subjects (0.33% reported having two or more first-degree relative with colorectal cancer or one first-degree relative with colorectal cancer diagnosed at age <50 years. Four subjects (0.07% had three or more first-degree relative with colorectal cancer. Conclusion: Based on the findings, we estimate that more than 570,000 subjects in the Iran in the age group≥20 years have at least two to three times increased risk of developing colorectal cancer which should be identified and encourage to participate in screening and surveillance protocols of colorectal cancer.

    Cancer is a unique disease characterized by abnormal growth of cells which have the ability to invade the adjacent tissues and sometimes even distant organs. The limited and contrasting evidence regarding the association of ABO blood groups with the different types of head and neck cancers in the Indian population warrants the need for the present study. To assess the relative risk of various Head & Neck cancers among different blood groups. Three hundred sixty two diagnosed cases of different type of head and neck cancers and 400 controls were selected from four hospitals of New Delhi, India. The information regarding the type of head and neck cancer was obtained from the case sheets of the patients regarding their socio demographic profile, dietary history using a structured performa. The information regarding type of cancer (cases only), ABO blood group was collected. Statistical Tests: The data was analysed using the SPSS 19 version. Chi square test and odd ratios were calculated. The level of significance was fixed at 5%. The O blood group was found to be most prevalent followed by B, A and AB among the cases as well as the controls. Oral cancer patients showed maximum number in blood group O followed by B, A and AB. Significant pattern of distribution was seen among the patients of esophageal cancer, laryngeal cancer and salivary gland cancer as well (p= 0.003, p=0.000 p=0.112 respectively. The present study reveals that there is an inherited element in the susceptibility or protection against different types of head and neck cancers. Blood group A was found to be a potential risk factor for the development of oral cancers, esophageal cancers and salivary gland cancers while blood group B was found to be a potential risk factor for laryngeal cancers.

    Pediatric cancer patients and their families face significant physical, emotional, and psychosocial challenges. Few studies have investigated how children manage these challenges and how parents may help in the process. This qualitative study aimed to explore common cancer-related stressors for children and to examine child coping and parental assistance in coping with these stressors during treatment. Fifteen children undergoing cancer treatment and their parents participated in semistructured interviews. Four themes emerged capturing cancer-related stressors: cancer treatment/side effects, distressing emotions, disruption in daily routines, and social challenges. Six themes emerged regarding child coping strategies that were classified within an approach/avoidance coping framework. Approach coping strategies included the following: cognitive restructuring, relaxation, practical strategies, seeking social support, and emotional expression. Distraction was the only avoidant coping strategy. Parents tended to encourage approach coping strategies (eg, cognitive restructuring, social support). Within families, few coping strategies were reported (child: M = 1.47, SD = 0.99; parent: M = 3.33, SD = 1.18), suggesting that early family-based interventions teaching coping techniques for cancer-related stressors may be beneficial.

    The combination of an increasing number of new cancer cases and improving survival rates has led to a large and rapidly growing population with unique health-care requirements. Exercise has been proposed as a strategy to help address the issues faced by cancer patients. Supported by a growing body of research, major health organizations commonly identify the importance of incorporating exercise in cancer care and advise patients to be physically active. This systematic review comprehensively summarizes the available epidemiologic and randomized controlled trial evidence investigating the role of exercise in the management of cancer. Literature searches focused on determining the potential impact of exercise on 1) cancer mortality and recurrence and 2) adverse effects of cancer and its treatment. A total of 100 studies were reviewed involving thousands of individual patients whose exercise behavior was assessed following the diagnosis of any type of cancer. Compared with patients who performed no/less exercise, patients who exercised following a diagnosis of cancer were observed to have a lower relative risk of cancer mortality and recurrence and experienced fewer/less severe adverse effects. The findings of this review support the view that exercise is an important adjunct therapy in the management of cancer. Implications on cancer care policy and practice are discussed. © The Author 2017. Published by Oxford University Press on behalf of the Johns Hopkins Bloomberg School of Public Health.

    The focus of the study is the analysis of changes in health-related quality of life in various cancer entities during and after an inpatient rehabilitation programme. In a multicentre longitudinal study, a total of 211 cancer patients (breast cancer: N = 84; prostate cancer: N = 90; colon cancer: N = 37) were asked about their quality of life (EORTC QLQ-C30; HADS) at the beginning, the end and 3 months after the end of the rehabilitation programme. In different domains of quality of life significant and mostly clinically relevant improvements were found during rehabilitation. The breast and prostate cancer patients improved most in emotional functioning, colon cancer patients in global quality of life. With regard to the severity of symptoms, the fatigue burden improved in breast and colon cancer patients, nausea in the prostate cancer patients. However, they are increases 3 months after rehabilitation. Functional burdens improved 3 months after the end of rehabilitation in the physical domain for all cancer patients. For breast cancer patients, emotional functioning decreased significantly 3 months after rehabilitation. An inpatient oncological rehabilitation programme can lead to an improvement in quality of life. © 2016 John Wiley & Sons Ltd.

    Anderson, Lindsey J; Albrecht, Eliette D; Garcia, Jose M

    2017-01-01

    Cachexia is a metabolic syndrome driven by inflammation and characterized by loss of muscle with or without loss of fat mass. In cancer cachexia, the tumor burden and host response induce increased inflammation, decreased anabolic tone, and suppressed appetite leading to the clinical presentation of reduced body weight and quality of life (QOL). There is no approved treatment for cancer cachexia, and commonly used nutritional and anti-inflammatory strategies alone have proven ineffective for management of symptoms. Several other pharmacological agents are currently in development and have shown promise as a clinical strategy in early-phase trials. Recently, it has been proposed that multimodal strategies, with an anabolic focus, initiated early in the disease/treatment progression may provide the most therapeutic potential for symptom management. Here we review the data from recent clinical trials in cancer cachexia including pharmacological, exercise, and nutritional interventions.

    Although the usefulness of mammography as a screening test for breast cancer is still in dispute, its use to patients over 50 years of age is valid. Since Wolfe first classified the breast parenchymal patterns of mammography into 4 patterns, many authors have adopted the criteria in studying the changes of the parenchymal patterns for certain ages and the risks for breast cancer of certain parenchymal patterns. Authors reviewed 49 cases of breast masses which diagnosed by mammography and by operation during the period from January 1978 to July 1983 at St. Mary Hospital, Catholic Medical College. The parenchymal tissue patterns were classified according to Wolfe into N1, P1, P2 and DY, Risk groups were classified into low risk group (N1, P1) and high group (P2, DY). On the basis of these criteria, benign and malignant disease were analyzed against the breast parenchymal patterns. The results and conclusions were as follows: 1. Age ranged from 16 years to 67 years with the most prevalent age being 4th and 5th decades. 2. Diagnoses were: fibroadenoma 17 cases, fibrous dysplasia 16 cases, ductal papilloma 3 cases, and cancer 13 cases. 3. Categorization of those 26 benign disease according to the Wolfe's criteria was: N1 6 cases, P1 10 cases, P2 9 cases and DY 11 cases. On the other hand, categorization of 13 cases of cancer was: N1 5 caes, P1 3 cases, P2 3 cases, and DY 2 cases. 4. Of 13 cases of cancer, 8 fell in the low risk group and remainder in the high risk group. There were no significant correlation between the parenchymal patterns and the incidence of breast cancer

    The aim of this study is to assess dental students' opinions of the dentists' role in primary prevention of human papillomavirus (HPV)-related oral cancer using a cross-sectional web-based survey. A questionnaire, containing questions about knowledge of HPV and oral cancer, confidence in head and neck examination and role of the dentist in preventing HPV-related oral cancer, was sent to all students of the Academic Centre of Dentistry Amsterdam (n = 912). One hundred and twenty-six (n = 126) students completed the questionnaire. Significantly, more master students (75%) than bachelor students (54.3%) were aware that HPV is a causative factor for oral cancer. Master students had more knowledge of HPV than bachelor students, but knowledge about HPV vaccination was irrespective of the study phase. The majority of dental students agreed that it is important to discuss HPV vaccination with patients. Eighty-nine percent of the students think that more education about symptoms of oral cancer will increase screening for oral cancer. Development of a protocol for screening in dental practices was considered even more important. According to dental students, dentists should discuss HPV as a risk factor for oral cancer with patients. Future dentists are willing to be involved in both primary and secondary prevention of HPV-related oral cancer. Therefore, screening for oral cancer and education about HPV vaccination should be integral elements of the dental curriculum.

    This paper aimed to determine the relationship between cancer information scanning and seeking experience of adolescents and cancer preventive behavior, perceived cancer risk, and levels of cancer- related knowledge. The study sample comprised 1,000 second-year students from 6 high schools: the general and vocational school systems were each represented by 1 boys', 1 girls', and 1 coeducational high school. In July 2011, trained researchers visited each classroom, explained the purpose of the study, distributed questionnaires to the students who agreed to participate, instructed them to complete the survey by self-reporting, and collected the completed questionnaires. The students who attended general high schools (as compared with vocational high schools), earned higher grades, consumed more vegetables, had a higher perceived cancer risk, and answered the cancer-related questions more correctly and had more cancer information scanning and seeking experience. These results reinforce the importance of cancer prevention health education. Furthermore, the results may help in preparing a strategy that enables people to acquire accurate cancer-related information easily and quickly.

    To evaluate the relationship between the clinical and pathological parameters of the primary tumor and disease-free survival (DFS) in a sample of hospital cases of invasive breast cancer. We performed a retrospective cohort study in 635 patients recruited at San Cecilio University Hospital in Granada (Spain) between 1994 and 2006. Information on the primary tumor and the outcomes of patients was collected by reviewing the medical records. Predictors of recurrence and/or metastasis and DFS (follow up of 3, 5 and 10 years) were analyzed by using Cox regression analysis. Multivariate models adjusted for age, tumor size, lymph nodal status, histological grade and estrogen and progesterone receptor expression showed a higher risk of recurrence and/or metastasis and lower DFS (adjusted relative risk, 95% confidence intervals) with tumor size (3 yrs: 3.00, 1.79-5.03; 5 yrs: 2.56, 1.65-3.98; 10 yrs: 2.16, 1.44-3.24), lymph nodal status (3 yrs: 4.58, 2.42-8.65; 5 yrs: 3.84, 2.35-6.30; 10 yrs: 3.08, 2.05-4.61), lymphovascular invasion (5 yrs: 1.88, 1.16-3.04; 10 yrs: 2.19, 1.43-3.35), multifocal and/or multicenter tumors (3 yrs: 2.69, 1.46-4.96; 5 yrs: 1.90, 1.08-3.35) and p53 protein expression (3 yrs: 2.03, 1.00-4.09). DFS was positively associated with an increased expression of progesterone receptor (3 yr: 0.48, 0.26-0.89; 5 yrs: 0.58, 0.35-0.97; 10 yrs: 0.59, 0.38-0.90). The biological characteristics of the primary tumor can be used to identify patients with distinctive prognoses and DFS, and could be helpful in making individual follow up strategies.

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

    Full Text Available This study contributes to the literature on the supervisors’ role in employee well-being by drawing on two separate lines of research: transformational leadership and organizational justice. The purpose of the study was to investigate the 'unique' contributions of transformational and fair leadership (justice behaviours of supervisors on work engagement and exhaustion among employees within the framework of the Job Demands-Resources model (Bakker and Demerouti, 2007. In determining the unique contributions, we additionally acknowledged the role of work characteristics. A questionnaire study was conducted among Finnish municipal employees in a variety of occupations (N = 333, 87% women. The analyses comprised fixed-order regression models with latent variables using Cholesky decomposition (de Jong, 1999 to examine unique contributions of highly correlating latent factors. The results showed no additive effects of transformational leadership above fair leadership in relation to work engagement, that is, fair leadership explained work engagement equally well. However, unfair leadership explained incremental variance in exhaustion beyond low levels of transformational leadership. Thus, our results suggest that transformational and fair leadership are interchangeable with respect to positive well-being, while concerning health impairment, unfair leadership is more detrimental than a lack of transformational leadership. Both forms of leadership demonstrated relationships with employee well-being that were partly independent from work characteristics (role clarity, autonomy and workload, thereby corroborating the specific role of leadership. Implications of the high empirical overlap between transformational and fair leadership are discussed from the point of view of leadership measurement and interpersonal affect within it.

    Visible oral and oropharyngeal premalignant lesions may be used to monitor for a second primary oral cancer. To control for bias, we focused on the visible oral and oropharyngeal premalignant lesions of patients with oral cancer with a positive betel-nut chewing habit. Visible oral and oropharyngeal premalignant lesions that can predict second primary oral cancers were studied. Nine hundred ninety-seven patients with positive betel-nut chewing habits and oral cancer were enrolled in this retrospective cohort study. We analyzed the relevance of their visible oral and oropharyngeal premalignant lesion incidence and relative clinicopathological variables to the development of a second primary oral cancer. Second primary oral cancer risk was significantly higher in patients with positive visible oral and oropharyngeal premalignant lesions (P oral and oropharyngeal premalignant lesions make it a potentially valuable marker in follow-ups of patients with a positive betel-nut chewing habit with oral cancer, especially young patients with heterogeneous leukoplakia. © 2017 Wiley Periodicals, Inc.

    The tradition of storytelling is an integral part of Alaska Native cultures that continues to be a way of passing on knowledge. Using a story-based approach to share cancer education is grounded in Alaska Native traditions and people’s experiences and has the potential to positively impact cancer knowledge, understandings, and wellness choices. Community health workers (CHWs) in Alaska created a personal digital story as part of a 5-day, in-person cancer education course. To identify engaging elements of digital stories among Alaska Native people, one focus group was held in each of three different Alaska communities with a total of 29 adult participants. After viewing CHWs’ digital stories created during CHW cancer education courses, focus group participants commented verbally and in writing about cultural relevance, engaging elements, information learned, and intent to change health behavior. Digital stories were described by Alaska focus group participants as being culturally respectful, informational, inspiring, and motivational. Viewers shared that they liked digital stories because they were short (only 2–3 min); nondirective and not preachy; emotional, told as a personal story and not just facts and figures; and relevant, using photos that showed Alaskan places and people.

    Full Text Available The life span of patients with primary and secondary immunodeficiency is increasing due to recent improvements in therapeutic strategies. Whilst, the incidence of primary immunodeficiencies (PIDs is 1:10.000 births, that of secondary immunodeficiencies is more common and are associated with post transplantation immune dysfunction or with immunosuppressive medication for human immunodeficiency virus (HIV or with human T-cell lymphotropic virus (HTLV infection.After infection, malignancy is the most prevalent cause of death in both children and adults with primary immunodeficiency disorders (PIDs. PIDs more often associated with cancer include common variable immunodeficiency (CVID, Wiskott Aldrich syndrome (WAS, ataxia-telangiectasia (AT and severe combined immunodeficiency (SCID. This suggests that a protective immune response against both infectious non-self (pathogens and malignant self-challenges (cancer exist. The increased incidence of cancer has been attributed to defective elimination of altered or transformed cells and/or defective immunity towards cancer cells. The concept of abberant immune surveillance occurring in PIDs is supported by evidence in mice and from patients undergoing immunosuppression after transplantation. Here, we discuss the importance of PID defects in the development of malignancies, the current limitations associated with molecular pathogenesis of these diseases and emphasize the need for further knowledge of how specific mutations can modulate the immune system to alter immunosurveillance and thereby play a key role in the etiology of malignancies in PID patients.

    Full Text Available Introduction: modern knowledge could protect against cancer for individuals in community with early stage and premalignat state. Screening of cancer is best instrument for early detection of malignancy. Between women’s cancers breast and cervical cancer have more incidence and mortality than other cancers . But could be prevented by simple and cheep screening programs. Despite specific statistics in Iran evidence shows that women’s participation in screening program is poor , so cancers are diagnosed in advanced stage. The purpose of this study was to identify major barriers and motivators for breast and cervical screening . Methods: This survey was a descriptive study in which 400 women participated in health and treatment centers in Yazd. Sampling method was done in two simple and random stages. Data was collected by inventory and questionnaire . Then data were analyzed by SPSS soft ware . Results: Findings showed that 80% of them never refereed to a health provider for clinical breast exam (C B E and only 3% of them did regularly C B E . 46% of them had never done pap smear and only 14.5 % of them did regularly pap smear. The findings showed that major motivators were as follow: advice of health’s personnel , using of contraceptive methods , and awareness of media. Also the major barriers were as follow : Not having knowledge of these exams , not having knowledge of the existence of these centers of education and practice , not having precious health problems , fear of examination , Embarrassment of examination and health providers not to teach them . to consider the most important barriers were propounded which showed that health education role to eliminate barriers for referring women for screening . Discussion: Based on the results of this sample , screening was the least expected . considering barriers and motivators observed it was revealed that health education was required for prevention of common women’s cancers.

    Full Text Available We have analyzed one year (July 2006–July 2007 of measurement data from a relatively clean background site located in dry savannah in South Africa. The annual-median trace gas concentrations were equal to 0.7 ppb for SO2, 1.4 ppb for NOx, 36 ppb for O3 and 105 ppb for CO. The corresponding PM1, PM2.5 and PM10 concentrations were 9.0, 10.5 and 18.8 μg m−3, and the annual median total particle number concentration in the size range 10–840 nm was 2340 cm−3. During Easterly winds, influence of industrial sources approximately 150 km away from the measurement site was clearly visible, especially in SO2 and NOx concentrations. Of gases, NOx and CO had a clear annual, and SO2, NOx and O3 clear diurnal cycle. Atmospheric new-particle formation was observed to take place in more than 90% of the analyzed days. The days with no new particle formation were cloudy or rainy days. The formation rate of 10 nm particles varied in the range of 0.1–28 cm−3 s−1 (median 1.9 cm−3 s−1 and nucleation mode particle growth rates were in the range 3–21 nm h−1 (median 8.5 nm h−1. Due to high formation and growth rates, observed new particle formation gives a significant contribute to the number of cloud condensation nuclei budget, having a potential to affect the regional climate forcing patterns.

    Basic igneous rocks, containing less than 52% SiO 2 , constitute an important part of the Finnish Archaean and Proterozoic crust. In the Archaean crust exist two units which contain the majority of the basic rocks. The Arcaean basic rocks are metavolcanics and situated in the Greenstone Belts of Eastern Finland. They are divided into two units. The greenstones of the lower one are tholeiites, komatiites and basaltic komatiites. The upper consists of bimodal series of volcanics and the basic rocks of which are Fe-tholeiites, basaltic komatiites and komatiites. Proterozoic basic rocks are divided into seven groups according to their ages. The Proterozoic igneous activity started by the volominous basic magmatism 2.44 Ga ago. During this stage formed the layered intrusions and related dykes in the Northern Finland. 2.2 Ga old basic rocks are situated at the margins of Karelian formations. 2.1 Ga aged Fe-tholeiitic magmatic activity is widespread in Eastern and Northern Finland. The basic rocks of 1.97 Ga age group are met within the Karelian Schist Belts as obducted ophiolite complexes but they occur also as tholeiitic diabase dykes cutting the Karelian schists and Archean basement. The intrusions and the volcanics of the 1.9 Ga old basic igneous activity are mostly encountered around the Granitoid Complex of Central Finland. Subjotnian, 1.6 Ga aged tholeiitic diabases are situated around the Rapakivi massifs of Southern Finland, and postjotnian, 1.2 Ga diabases in Western Finland where they form dykes cutting Svecofennian rocks

    We have measured water/n-octanol partition coefficients, pK(a) values, heme binding constants, and heme aggregation inhibition activity of a series of ruthenium-pi-arene-chloroquine (CQ) complexes recently reported to be active against CQ-resistant strains of Plasmodium falciparum. Measurements of heme aggregation inhibition activity of the metal complexes near water/n-octanol interfaces qualitatively predict their superior antiplasmodial action against resistant parasites, in relation to CQ; we conclude that this modified method may be a better predictor of antimalarial potency than standard tests in aqueous acidic buffer. Some interesting tendencies emerge from our data, indicating that the antiplasmodial activity is related to a balance of effects associated with the lipophilicity, basicity, and structural details of the compounds studied.

    Effective radiation protection program is vital to ensure the safety of workers involved in work related to radiation. This objective of this research was to determine the level of awareness towards radiation protection among the workers at Malaysian Nuclear Agency. Questionnaire forms containing questions related to relevant work experience and knowledge of radiation safety were distributed to a group of identified radiation workers. The hypothesis of this study is that all workers involved have high levels of awareness and basic knowledge as they work in an institution which activities frequently and routinely involve radiation. The result of this research show that the level of awareness and knowledge of the respondents were at a good level, with an average overall score of 87.2% showed a high level of awareness among respondents. Overall, highest academic qualifications did not affect the level of knowledge (p > 0.05). In contrast, service tenure affects their level of knowledge (p < 0.05). (author)

The protein isoforms produced are tightly regulated in normal development but are mostly deregulated in various cancers. In HIV-infected individuals with AIDS, there is an increase in aberrant alternative splicing, resulting in an increase in HIV/AIDS-related cancers, such as Kaposi’s sarcoma, non-Hodgkin’s lymphoma, and cervical cancer. This aberrant splicing leads to abnormal production of protein and is caused by mutations in cis-acting elements or trans-acting factors in angiogenesis-related genes. Restoring the normal regulation of alternative splicing of angiogenic genes would alter the expression of protein isoforms and may confer normal cell physiology in patients with these cancers. This review highlights the abnormalities in alternative splicing of angiogenesis-related genes and their implication in HIV/AIDS-related cancers. This allows us to gain an insight into the pathogenesis of HIV/AIDS-related cancer and in turn elucidate the therapeutic potential of alternatively spliced genes in HIV/AIDS-related malignancies.

    Although great strides have been made in increasing equality and inclusion in organizations, a number of stigmatized groups are overlooked by diversity initiatives, including people with a history of cancer. To examine the workplace experiences of these individuals in selection contexts, we conducted 3 complementary studies that assess the extent to which cancer is disclosed, the stereotypes associated with cancer in the workplace, and discrimination resulting from these stereotypes. In a pilot study, we surveyed 196 individuals with a history of cancer (across 2 samples) about their workplace disclosure habits. In Study 1, we explored stereotypes related to employees with a history of cancer using the framework outlined by the stereotype content model. In Study 2, we used a field study to assess the experiences of job applicants who indicated they were "cancer survivors" (vs. not) with both formal and interpersonal forms of discrimination. This research shows that cancer is disclosed at relatively high rates (pilot study), those with a history of cancer are stereotyped as being higher in warmth than competence (Study 1), and the stereotypes associated with those who have had cancer result in actual discrimination toward them (Study 2). We discuss the theory behind these findings and aim to inform both science and practice with respect to this growing workplace population. (c) 2016 APA, all rights reserved).

    Health-related quality of life (HRQL) data are becoming an important supplement to information pertaining to treatment outcome for cancer patients. The purpose of this study was to evaluate the HRQL outcome for oral cancer survivors after surgery plus postoperative radiotherapy (RT) and to investigate the variables associated with their HRQL. Sixty-six oral cancer patients with cancer-free survival after surgery plus postoperative RT of >2 years were enrolled. The Short Form-36 (SF-36) questionnaire in the Taiwan Chinese version was self-reported by all participants at the clinics. The linear regression model was used to analyze the socio-demographic and medical-related variables correlated with the physical component summary (PCS) and mental component summary (MCS) in SF-36. The mean scores of the eight functional domains in the SF-36 were markedly lower for oral cancer survivors compared with the Taiwanese and US norms. Those with older age, lower annual family income, more advanced cancer stage and flap reconstruction had significantly worse PCS, and those with lower annual family income, unemployment and more advanced cancer stage reported significantly worse MCS. This model accounts for 63% of variance in PCS, and 51% in MCS. These results provided patient-reported evidence that oral cancer survivors lived with a worse HRQL compared with the general Taiwanese population. Socio-economic factors and cancer stage were important factors correlated with their HRQL. (authors)

    Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental pollutants, known human lung carcinogens, and potent mammary carcinogens in laboratory animals. However, the association between PAHs and breast cancer in women is unclear. Vehicular traffic is a major ambient source of PAH exposure. Our study aim was to evaluate the association between residential exposure to vehicular traffic and breast cancer incidence. Residential histories of 1,508 participants with breast cancer (case participants) and 1,556 particpants with no breast cancer (control participants) were assessed in a population-based investigation conducted in 1996-1997. Traffic exposure estimates of benzo[a]pyrene (B[a]P), as a proxy for traffic-related PAHs, for the years 1960-1995 were reconstructed using a model previously shown to generate estimates consistent with measured soil PAHs, PAH-DNA adducts, and CO readings. Associations between vehicular traffic exposure estimates and breast cancer incidence were evaluated using unconditional logistic regression. The odds ratio (95% CI) was modestly elevated by 1.44 (0.78, 2.68) for the association between breast cancer and long-term 1960-1990 vehicular traffic estimates in the top 5%, compared with below the median. The association with recent 1995 traffic exposure was elevated by 1.14 (0.80, 1.64) for the top 5%, compared with below the median, which was stronger among women with low fruit/vegetable intake [1.46 (0.89, 2.40)], but not among those with high fruit/vegetable intake [0.92 (0.53, 1.60)]. Among the subset of women with information regarding traffic exposure and tumor hormone receptor subtype, the traffic-breast cancer association was higher for those with estrogen/progesterone-negative tumors [1.67 (0.91, 3.05) relative to control participants], but lower among all other tumor subtypes [0.80 (0.50, 1.27) compared with control participants].

    In July 2010, at the Muscle Fatigue Meeting, I presented an overview of Chronic Fatigue Syndrome and Cancer Related Fatigue, emphasizing a critical interpretation of the potential association between Chronic Fatigue Syndrome and Cancer Related Fatigue and a newly discovered retrovirus: Xenotropic Murine Related Virus. Since this association was hotly debated at that time, I suggested at the Meeting that it was wrong and most likely due to the identification of the wrong virus culprit. Today, 20 months after the Meeting, the first part of our prediction has turned out to be correct, as Xenotropic Murine Related Virus was shown to be a laboratory-created artefact. Still, the potential association of fatigue-syndromes with an infection (most likely viral) is sustained by a plethora of evidence and this overview will initially summarize data suggesting prior viral infection(s). The principal hypothesized mechanisms for both peripheral and central Chronic Fatigue Syndrome/Cancer Related Fatigue will be then summarized, also indicating plausible associations and triggering factors. All evidence accrued so far suggests that further research work should be performed in this interesting area and in order to identify an infectious agent for Chronic Fatigue Syndrome/Cancer Related Fatigue.

    Cancer constitutes a momentous health burden in our society. Critical information on cancer may be hidden in its signaling pathways. However, even though a large amount of money has been spent on cancer research, some critical information on cancer-related signaling pathways still remains elusive. Hence, new works towards a complete understanding of cancer-related signaling pathways will greatly benefit the prevention, diagnosis, and treatment of cancer. We propose the node-weighted Steiner tree approach to identify important elements of cancer-related signaling pathways at the level of proteins. This new approach has advantages over previous approaches since it is fast in processing large protein-protein interaction networks. We apply this new approach to identify important elements of two well-known cancer-related signaling pathways: PI3K/Akt and MAPK. First, we generate a node-weighted protein-protein interaction network using protein and signaling pathway data. Second, we modify and use two preprocessing techniques and a state-of-the-art Steiner tree algorithm to identify a subnetwork in the generated network. Third, we propose two new metrics to select important elements from this subnetwork. On a commonly used personal computer, this new approach takes less than 2 s to identify the important elements of PI3K/Akt and MAPK signaling pathways in a large node-weighted protein-protein interaction network with 16,843 vertices and 1,736,922 edges. We further analyze and demonstrate the significance of these identified elements to cancer signal transduction by exploring previously reported experimental evidences. Our node-weighted Steiner tree approach is shown to be both fast and effective to identify important elements of cancer-related signaling pathways. Furthermore, it may provide new perspectives into the identification of signaling pathways for other human diseases.

    In 1978, asbestos-related occupational cancers were added to the Spanish list of occupational diseases. However, there are no full accounts of compensated cases since their inclusion. To analyze the cases of asbestos-related cancer recognized as occupational in Spain between 1978 and 2011. Cases were obtained from the Spanish Employment Ministry. Specific incidence rates by year, economic activity, and occupation were obtained. We compared mortality rates of mesothelioma and bronchus and lung cancer mortality in Spain and the European Union. Between 1978 and 2011, 164 asbestos-related occupational cancers were recognized in Spain, with a mean annual rate of 0·08 per 10(5) employees (0·13 in males, 0·002 in females). Under-recognition rates were an estimated 93·6% (males) and 99·7% (females) for pleural mesothelioma and 98·8% (males) and 100% (females) for bronchus and lung cancer. In Europe for the year 2000, asbestos-related occupational cancer rates ranged from 0·04 per 10(5) employees in Spain to 7·32 per 10(5) employees in Norway. These findings provide evidence of gross under-recognition of asbestos-related occupational cancers in Spain. Future work should investigate cases treated in the National Healthcare System to better establish the impact of asbestos on health in Spain.

    Increasing evidence suggests that the abnormality of microRNAs (miRNAs) and their downstream targets is frequently implicated in the pathogenesis of human cancers, however, the clinical benefit of causal miRNA-target interactions has been seldom studied. Here, we proposed a computational method to optimize prognosis-related key miRNA-target interactions by combining transcriptome and clinical data from thousands of TCGA tumors across 16 cancer types. We obtained a total of 1,956 prognosis-related key miRNA-target interactions between 112 miRNAs and 1,443 their targets. Interestingly, these key target genes are specifically involved in tumor progression-related functions, such as 'cell adhesion' and 'cell migration'. Furthermore, they are most significantly correlated with 'tissue invasion and metastasis', a hallmark of metastasis, in ten distinct types of cancer through the hallmark analysis. These results implicated that the prognosis-related key miRNA-target interactions were highly associated with cancer metastasis. Finally, we observed that the combination of these key miRNA-target interactions allowed to distinguish patients with good prognosis from those with poor prognosis both in most TCGA cancer types and independent validation sets, highlighting their roles in cancer metastasis. We provided a user-friendly database named miRNATarget (freely available at http://biocc.hrbmu.edu.cn/miRNATar/), which provides an overview of the prognosis-related key miRNA-target interactions across 16 cancer types.

    Full Text Available Identification and characterization of crucial gene target(s that will allow focused therapeutics development remains a challenge. We have interrogated the putative therapeutic targets associated with the transcription factor Grainy head-like 2 (GRHL2, a critical epithelial regulatory factor. We demonstrate the possibility to define the molecular functions of critical genes in terms of their personalized expression profiles, allowing appropriate functional conclusions to be derived. A novel methodology, relative expression analysis with gene-set pairs (RXA-GSP, is designed to explore the potential clinical utility of cancer-biology discovery. Observing that Grhl2-overexpression leads to increased metastatic potential in vitro, we established a model assuming Grhl2-induced or -inhibited genes confer poor or favorable prognosis respectively for cancer metastasis. Training on public gene expression profiles of 995 breast cancer patients, this method prioritized one gene-set pair (GRHL2, CDH2, FN1, CITED2, MKI67 versus CTNNB1 and CTNNA3 from all 2717 possible gene-set pairs (GSPs. The identified GSP significantly dichotomized 295 independent patients for metastasis-free survival (log-rank tested p = 0.002; severe empirical p = 0.035. It also showed evidence of clinical prognostication in another independent 388 patients collected from three studies (log-rank tested p = 3.3e-6. This GSP is independent of most traditional prognostic indicators, and is only significantly associated with the histological grade of breast cancer (p = 0.0017, a GRHL2-associated clinical character (p = 6.8e-6, Spearman correlation, suggesting that this GSP is reflective of GRHL2-mediated events. Furthermore, a literature review indicates the therapeutic potential of the identified genes. This research demonstrates a novel strategy to integrate both biological experiments and clinical gene expression profiles for extracting and elucidating the genomic

    Patients with cancer are at particularly high risk for malnutrition because both the disease and its treatments threaten their nutritional status. Yet cancer-related nutritional risk is sometimes overlooked or under-treated by clinicians, patients, and their families. The European Society for Clinical Nutrition and Metabolism (ESPEN) recently published evidence-based guidelines for nutritional care in patients with cancer. In further support of these guidelines, an ESPEN oncology expert group met for a Cancer and Nutrition Workshop in Berlin on October 24 and 25, 2016. The group examined the causes and consequences of cancer-related malnutrition, reviewed treatment approaches currently available, and built the rationale and impetus for clinicians involved with care of patients with cancer to take actions that facilitate nutrition support in practice. The content of this position paper is based on presentations and discussions at the Berlin meeting. The expert group emphasized 3 key steps to update nutritional care for people with cancer: (1) screen all patients with cancer for nutritional risk early in the course of their care, regardless of body mass index and weight history; (2) expand nutrition-related assessment practices to include measures of anorexia, body composition, inflammatory biomarkers, resting energy expenditure, and physical function; (3) use multimodal nutritional interventions with individualized plans, including care focused on increasing nutritional intake, lessening inflammation and hypermetabolic stress, and increasing physical activity.

    Symptoms of depression and cancer-related fatigue (CRF) are common among breast cancer patients postchemotherapy and may seriously impair quality of life (QoL). This study aimed to assess the relationship between depression and CRF in breast cancer patients postchemotherapy and to examine their relationships to optimism and to threat and challenge appraisals. Participants included 95 breast cancer patients (stages 1-3) 1 to 6 months after completion of chemotherapy. Patients submitted personal and medical details and completed the following: physical symptom questionnaires (EORTC QLQ-C30, and QLQ-BR23), a symptoms of depression questionnaire (CES-D), the Fatigue Symptom Inventory (FSI), the Life Orientation Test (LOT-R), and a stress appraisals questionnaire. We found levels of depression, CRF, and appraisals of cancer as a threat to bemoderate and levels of optimism and appraisals of cancer as a challenge to be high. Depression and CRF were positively associated. A multivariate regression analysis revealed that 51% of the CRF variancewas explained; physical symptoms and threat appraisal were significantly associated with CRF. A 67% of the CRF variance of depression was explained; challenge and threat appraisals were significantly associated with depression [corrected]. Although CRF and depression were often experienced simultaneously and both were found to be higher among individuals who gave higher appraisals of cancer as a threat, only depression was related to optimism and challenge appraisals, while CRF was related mainly to intensity of physical symptoms. The different pattern of associations between optimism and appraisals warrants further clinical attention as well as future study.

    In the European Association for Palliative Care recommendations for cancer pain management, there was no consensus regarding the indications, titration, or monitoring of methadone. This national, randomized, multicenter trial aimed to compare two methadone titration methods (stop-and-go vs. progressive) in patients with cancer-related pain who were inadequately relieved by or intolerant to Level 3 opioids. The primary end point was the rate of success/failure at Day 4, defined as pain relief (reduction of at least two points on the visual scale and a pain score methods were considered equally easy to perform by nearly 60% of the clinicians. Methadone is an effective and sustainable second-line alternative opioid for the treatment of cancer-related pain. The methods of titration are comparable in terms of efficacy, safety, and ease of use. Copyright © 2016 American Academy of Hospice and Palliative Medicine. Published by Elsevier Inc.

    Current guidelines derived from a pre-human papilloma virus (HPV) era in oropharyngeal cancer do not recommend routine surveillance imaging. We aimed to analyze the method of recurrence detection in HPV+ disease to determine a role for follow-up imaging. All HPV+ and HPV- oropharyngeal cancer patients treated at our institution from 2005-2016 with biopsy-proven recurrence were identified and their method of recurrence detection was analyzed. A total of 16 HPV+ oropharyngeal cancer patients were identified to have recurrence, 12 (75%) of which experienced distant recurrence and 13 (81.3%) were detected asymptomatically with imaging at a median time of 19.7 months after initial treatment and verifying no residual disease. Twelve (75%) detections were with PET-CT. While HPV- patients (17 patients) also have a high rate of asymptomatic detection (16 patients, 94.1%), their 3-year post-recurrence survival was significantly lower at 6.5% compared to 83.6% for the HPV+ group (pHPV+ patients, a large proportion of failures are asymptomatic distant metastases, which occur beyond 6 months following treatment completion, and are detected with whole body imaging alone. In light of long term post-recurrence survival observed, this preliminary data suggests that routine surveillance imaging should be further studied for HPV+ disease.

    Background and purpose: To assess the correlation between different general and organ specific quality of life and morbidity scoring methods in a cohort of men treated with radical radiotherapy for prostate cancer. Materials and methods: Men who had been treated with radical radiotherapy (50 Gy in 16 fractions over 21 days) for localized prostate cancer more than 3 years previously and who had no evidence of recurrent disease were invited to take part in the study. A total of 101 of 135 invited patients agreed and completed LENT/SOMA, UCLA Prostate Cancer Index, and 36 item RAND Health survey questionnaires. Results: The patients had comparable results with other published series with respect to the UCLA and SF-36 indices. There was significant correlation between the corresponding parts of the UCLA and LENT/SOMA scales (P<0.0005). However, for the same symptoms, a patient tended to score lower (worse) on the UCLA scale in comparison to LENT/SOMA. The relationship between the average LENT/SOMA score and maximum score was also not straightforward with each set of data revealing different information. Conclusions: The LENT/SOMA questions were, in the main, more wide-ranging and informative than the UCLA index. It is helpful to give both the overall and maximum LENT/SOMA scores to most efficiently use all of the data. There may need to be a further LENT/SOMA question to allow both symptoms of tenesmus and faecal urgency to be fully addressed

    Objective: To analyze breast cancer bone metastasis related gene-CXCR4. Methods: This research screened breast cancer bone metastasis related genes by high-flux gene chip. Results:It was found that the expressions of 396 genes were different including 165 up-regulations and 231 down-regulations. The expression of chemokine receptor CXCR4 was obviously up-regulated in the tissue with breast cancer bone metastasis. Compared with the tissue without bone metastasis, there was significant difference, which indicated that CXCR4 played a vital role in breast cancer bone metastasis. Conclusions: The bioinformatics analysis of CXCR4 can provide a certain basis for the occurrence and diagnosis of breast cancer bone metastasis, target gene therapy and evaluation of prognosis.

    Geographic pattern of lung cancer mortality in Fukuoka Prefecture showed elevated mortalities among males in the Chikuho district where many coal-mines had long been operated as one of the biggest coal-mining areas in Japan. The analysis in relations of occupations to lung cancer mortality revealed that consistently significant correlations exist between lung cancer mortality, and mining and quarrying occupations in every census year after World War II. No other occupations showed consistent relations to lung cancer though a few significant correlations were found only in the recent years. The results appear to suggest that elevated risk of lung cancer among coal-mining workers may exist and deserve further analytical study.

  5. Genetic variants in hormone-related genes and risk of breast cancer.

    Directory of Open Access Journals (Sweden)

    Full Text Available Sex hormones play a key role in the development of breast cancer. Certain polymorphic variants (SNPs and repeat polymorphisms in hormone-related genes are associated with sex hormone levels. However, the relationship observed between these genetic variants and breast cancer risk has been inconsistent. We conducted a case-control study nested within two prospective cohorts to assess the relationship between specific genetic variants in hormone-related genes and breast cancer risk. In total, 1164 cases and 2111 individually-matched controls were included in the study. We did not observe an association between potential functional genetic polymorphisms in the estrogen pathway, SHBG rs6259, ESR1 rs2234693, CYP19 rs10046 and rs4775936, and UGT1A1 rs8175347, or the progesterone pathway, PGR rs1042838, with the risk of breast cancer. Our results suggest that these genetic variants do not have a strong effect on breast cancer risk.

    Cancer may have a significant financial impact on patients, but the characteristics that predispose patients to cancer-related financial hardship are poorly understood. We investigated factors associated with cancer-related financial stress and strain in breast and prostate cancer survivors in Ireland, which has a complex mixed public-private healthcare system. Postal questionnaires were distributed to 1373 people diagnosed with cancer 3-24 months previously identified from the National Cancer Registry Ireland. Outcomes were cancer-related financial stress (impact of cancer diagnosis on household ability to make ends meet) and financial strain (concerns about household financial situation since cancer diagnosis). Modified Poisson regression was used to estimate relative risks (RR) for factors associated with cancer-related financial stress and strain. Seven hundred forty survivors participated (response rate = 54 %). Of the respondents, 48 % reported cancer-related financial stress and 32 % cancer-related financial strain. Compared to those employed at diagnosis, risk of cancer-related financial stress was significantly lower in those not working (RR = 0.71, 95 % CI 0.58-0.86) or retired (RR = 0.48, 95 % CI 0.34-0.68). It was significantly higher in those who had dependents; experienced financial stress pre-diagnosis; had a mortgage/personal loans; had higher direct medical out-of-pocket costs; and had increased household bills post-diagnosis. For cancer-related financial strain, significant associations were found with dependents, pre-diagnosis employment status and pre-diagnosis financial stress; risk was lower in those with higher direct medical out-of-pocket costs. Cancer-related financial stress and strain are common. Pre-diagnosis employment status and financial circumstances are important predictors of post-diagnosis financial wellbeing. These findings could inform development of tools to identify patients/survivors most in need of financial

    2017-08-01

    Smoking is a risk factor in at least 18 cancers, and approximately two-thirds of cancer survivors continue smoking following diagnosis. Text mining of survivors' online posts related to smoking and quitting could inform strategies to reduce smoking in this vulnerable population. We identified posts containing smoking/cessation-related keywords from the Cancer Survivors Network (CSN), an online cancer survivor community of 166 000 members and over 468 000 posts since inception. Unsupervised topic model analysis of posts since 2000 using Latent Dirichlet Allocation extracted 70 latent topics which two subject experts inspected for themes based on representative terms. Posterior analysis assessed the distribution of topics within posts, and the range of themes discussed across posts. Less than 1% of posts (n = 3998) contained smoking/cessation-related terms, and covered topics related to cancer diagnoses, treatments, and coping. The most frequent smoking-related topics were quit smoking methods (5.4% of posts), and the environment for quitters (2.9% of posts), such as the stigma associated with being a smoker diagnosed with cancer and lack of empathy experienced compared to nonsmokers. Smoking as a risk factor for one's diagnosis was a primary topic in only 1.7% of smoking/cessation-related posts. The low frequency of smoking/cessation-related posts may be due to expected criticism/stigma for smoking but may also suggests a need for health care providers to address smoking and assist with quitting in the diagnostic and treatment process. Topic model analysis revealed potential barriers that should be addressed in devising clinical or population-level interventions for cancer survivors who smoke. Although smoking is a major risk factor for cancer, little is known about cancer patients' or survivors' views or concerns about smoking and quitting. This study used text mining of posts to an online community of cancer patients and survivors to investigate contexts in which

    Late physical and emotional effects of cancer treatment pose a burden for adolescent and young adult survivors of childhood cancer, including family milestone achievement. This brief report examined links between ongoing cancer-related post-traumatic stress symptoms (CR-PTSS) and family milestone achievement. Survivors (n = 51; M age  = 24.73, SD = 8.20) completed CR-PTSS and family formation questionnaires. Descriptive statistics, univariate parameter-constraints, and correlation analyses examined relations among study variables. Ongoing intrusive thoughts and hyperarousal were negatively linked to family identity development and family achievement. Findings from the present study provide support that ongoing CR-PTSS may be a barrier to family formation. © 2018 Wiley Periodicals, Inc.

    The scored Patient-Generated Subjective Global Assessment (PG-SGA) is considered to be the most appropriate tool for detecting malnutrition in cancer patients. In particular, malignant tumours derived from the gastrointestinal tract may impair nutrient intake and absorption and cause malnutrition. We carried out a cross-sectional study to assess the nutritional status and related factors of patients with gastrointestinal cancer. Nutritional status was determined using the scored PG-SGA in patients (n 498) with advanced gastrointestinal cancer admitted to the Gastrointestinal Medical Oncology Unit at Beijing Cancer Hospital between 1 August 2012 and 28 February 2013. The possible related factors including age, sex, hospitalisation frequency and pathology were explored. We found that 98% of the patients required nutrition intervention and 54% of the patients required improved nutrition-related symptom management and/or urgent nutritional support (PG-SGA score ≥9). Factors related to malnutrition were age (r 0.103, Pcancer had a lower risk of malnutrition than patients with other types of gastrointestinal cancer (F=35.895, Pnutritional status of gastrointestinal patients, especially those at a higher risk of malnutrition, such as elderly patients, those hospitalised for the first time, male patients and those with other types of gastrointestinal cancer except rectal cancer. The nutritional status of these patients should be evaluated and they should be given proper nutrition education and nutritional support in a timely manner.

    To elucidate the causes of cancer death in Japanese families with Lynch syndrome (LS). The distributions of cancer deaths in 485 individuals from 67 families with LS (35, 30, and two families with MutL homologue 1 (MLH1), MSH2, and MSH6 gene mutations, respectively), obtained from the Registry of the Japanese Society for Cancer of the Colon and Rectum were analyzed. Among 98 cancer deaths of first-degree relatives of unknown mutation status, 53%, 19%, 13% (among females), 7% (among females) and 5% were due to colorectal, gastric, uterine, ovarian, and hepatobiliary cancer, respectively. The proportion of deaths from extra-colonic cancer was significantly higher in families with MSH2 mutation than in those with MLH1 mutation (p=0.003). In addition to colonic and uterine cancer, management and surveillance targeting gastric, ovarian and hepatobiliary cancer are considered important for Japanese families with LS. Extra-colonic cancer in families with MSH2 mutation might require for more intensive surveillance. Copyright© 2016 International Institute of Anticancer Research (Dr. John G.

    2012-01-01

    Diet plays a vital role in the management of cancer because they are the source of important physiologically functional components. Scientific observations support the idea that dietary supplement can prevent breast cancer recurrences. Strong correlations are established between the high intake of saturated fat and the incidence of different types of cancer. It is found that chronic alcohol consumption is associated with increased risk of cancers of oral cavity, pharynx, esophagus, and larynx. Again, some evidences are also found regarding phosphorous, glutamate level in the body, and incidence of cancer. Different physiologically functional components are found in the dietary materials. Fibers, the major dietary components, have long been recognized for the unique properties in the treatment of cancer, which are related to its antineoplastic functions. Antioxidant rich diet has been added to the list of cancer-preventing dietary components. Also, recently published research has shown that natural carotenoids in the diet leads to a normalization of body epithelial cells and protects against the risk of stomach and esophagus cancer, and improves the immune system's response. Again, fruit juices, processed vegetable juices, orange peel, green tea, vitamins, flavonoids, and trace materials have cancer inhibitory properties. Clearly, there has been increasing recognition of chemoprotective functions. Now, it can be recognized for another kind of functionality for the improvement of the health of mankind.

    Full Text Available Diet plays a vital role in the management of cancer because they are the source of important physiologically functional components. Scientific observations support the idea that dietary supplement can prevent breast cancer recurrences. Strong correlations are established between the high intake of saturated fat and the incidence of different types of cancer. It is found that chronic alcohol consumption is associated with increased risk of cancers of oral cavity, pharynx, esophagus, and larynx. Again, some evidences are also found regarding phosphorous, glutamate level in the body, and incidence of cancer. Different physiologically functional components are found in the dietary materials. Fibers, the major dietary components, have long been recognized for the unique properties in the treatment of cancer, which are related to its antineoplastic functions. Antioxidant rich diet has been added to the list of cancer-preventing dietary components. Also, recently published research has shown that natural carotenoids in the diet leads to a normalization of body epithelial cells and protects against the risk of stomach and esophagus cancer, and improves the immune system′s response.

    Kuan-Sin-Yin (KSY) is a traditional Chinese medicine (TCM) decoction, which has been shown to have cytostatic effects on cancer cells and involved in the TCM theory of promoting yin-yang balance.Sonce many cancer patients suffer from autonomic dysfunction (AD), which correspond to yin-yang imbalance in TCM. The aim of this study is to evaluate the possible effect of KSY in metastatic colon cancer (mCRC) patients with AD. We conducted a single-group experiment. Total 52 qualified patients were enrolled. Participants took the KSY daily for 2 weeks. The primary outcome was KSY efficacy as reflected in the heart rate variability (HRV) and electrical conductivity (µA) over 12 meridian points. Autonomic function was examined before and after the KSY intervention. The vagal and sympathetic tone were recorded by HRV; 12 meridian energies were measured using a meridian energy analysis device. Secondary outcomes were cancer-related symptoms and patient quality of life (QoL). The results showed that the KSY intervention improved AD via increasing the vagal tone (HF: P = .041), but not the sympathetic tone (LF: P = .154); total autonomic activity was significantly enhanced (HRV activity: P = .013). Intriguingly, energy increased more over the yin meridian (P = .010) than over the yang meridian (P = .015). Cancer-related symptoms and QoL were significantly improved (P yin-yang concept of energy. © The Author(s) 2015.

    Obesity continues to be a major global problem. Various cancers are related to obesity and proper understanding of their aetiology, especially their molecular tumour biology is important for early diagnosis and better treatment. Genes play an important role in the development of obesity. Few genes such as leptin, leptin receptor encoded by the db (diabetes), pro-opiomelanocortin, AgRP and NPY and melanocortin-4 receptors and insulin-induced gene 2 were linked to obesity. MicroRNAs control gene expression via mRNA degradation and protein translation inhibition and influence cell differentiation, cell growth and cell death. Overexpression of miR-143 inhibits tumour growth by suppressing B cell lymphoma 2, extracellular signal-regulated kinase-5 activities and KRAS oncogene. Cancers of the breast, uterus, renal, thyroid and liver are also related to obesity. Any disturbance in the production of sex hormones and insulin, leads to distortion in the balance between cell proliferation, differentiation and apoptosis. The possible mechanism linking obesity to cancer involves alteration in the level of adipokines and sex hormones. These mediators act as biomarkers for cancer progression and act as targets for cancer therapy and prevention. Interestingly, many anti-cancerous drugs are also beneficial in treating obesity and vice versa. We also reviewed the possible link in the mechanism of few drugs which act both on cancer and obesity. The present review may be important for molecular biologists, oncologists and clinicians treating cancers and also pave the way for better therapeutic options.

    Few studies have explored young children's understanding of cancer and health-related behaviours yet this is essential to develop health promotion initiatives that build on young children's current knowledge levels and awareness. An exploratory descriptive design using the 'draw and write' technique was used to investigate children's views of cancer and health behaviours. The sample included 195 children aged eight to 11 years from five schools in deprived, affluent and rural locations in Scotland. When asked about cancer children demonstrated a good level of awareness by responding with text and drawings about the what they understood cancer to be; types of cancer; causes of cancer; what happens to people who have cancer; their personal experience of cancer and the emotions they associated with cancer. Older children, and children attending affluent schools, have more defined ideas about the causes of cancer and awareness of broader issues such as the risk of passive smoking or the potential impact on the family. Factors such as alcohol and illegal drugs were only reported by children attending schools in deprived locations. Children demonstrated considerable knowledge about healthy and unhealthy lifestyle behaviours; however, it is not clear whether this knowledge translates into their behaviours or the choices offered within their home environment. Children view cancer in a negative way from an early age, even without personal experience. There is a need to demystify cancer in terms of its causes, how to recognize it, how it is treated and to publicize improved survival rates. There is a need for targeted and developmentally appropriate approaches to be taken to health education in schools, with an awareness of the influence of the media on children's information. Strategies should take into consideration the socio-economic and cultural contexts of children's lives which influence their choices and behaviours. © 2010 Blackwell Publishing Ltd.

    Several experimental studies have been studied in France in the field of low exposures to radon. The animal studies confirm the increase of ling cancer risk for exposures less than 100 units of exposures. A synthesis is actually running in the frame of an European programme coordinated by the Laboratory of epidemiology from the Institute of radiation protection and nuclear safety (I.R.S.N.). It will describe the different steps of the carcinogenesis brought into play during this chronic exposure at the level of bronchi epithelium by grouping the whole of data coming from the follow up of uranium miners and experimental studies

    In the previous studies of this project, binding activities and growth inhibitory effects of estrogen-related compounds (EC) were investigated in breast cancer cell lines, FCM-7 and MDA-MS-231. It was shown that EC such as 2-hydroxy estron, 2-hydroxy estrogen and estrogen significantly inhibited the growth of these cells and had highly binding activities to their estrogen receptors. Here, an investigation was made on the involvement of these compounds in intracellular signaling pathways. Mitogen activated protein (MAP)-kinase cascade is regarded as one of the important intracellular signaling pathways and MAPK-kinase positioned at the most downstream region has been known to migrate from cytoplasm to the nucleus associating with progressing of a cell growth and differentiation. So, correlation of MAP-kinase with the binding activity of ERC onto breast cells or with the growth repression was investigated. Since it has been shown that MAP.- and MAPK-kinase were activated in FCM-7 cells cultured with EGF, the binding activity of ERC was assessed in the presence of EGF. The binding activities to FCM-7 cells were, however, not affected by the addition of MAP-kinase. Although significant growth inhibitory effects of 2-hydroxy estron and 2-hydroxy estrogen on FCM-7 cells were confirmed as shown in the previous study, either of treatment with PD98059, an inhibitor for MAPK-kinase or expression of MKP3, a specific phosphatase for MAPK-kinase caused a repression of cell growth. These results suggest that MAP-kinase might be involved in the growth of breast cancer cells and cancer cell growth would be also affected by activation of MAP-kinase cascade. (M.N.)

    Full Text Available Filaggrin proteins are expressed in the skin, oral cavity, oesophagus, and cervical mucose. Loss-of-function mutations in the filaggrin gene (FLG reduce filaggrin expression and cause an impaired skin barrier function. We hypothesized that FLG mutation carriers would be more susceptible to human papillomavirus (HPV infection and thus a higher risk of HPV-related cancer and pre-cancer. We investigated the association of the FLG genotype with incidence of HPV-related cancer of cervix, vagina, vulva, penis, anus and head and neck, and pre-cancer of the cervix.We included 13,376 persons from four population-based studies conducted in the same background population in Copenhagen, Denmark. Participants were genotyped for the most common FLG mutations in Europeans. Information on cancer was obtained from The Danish Cancer Registry until 11 July 2011.There were 489 cases of prevalent and 97 cases of incident HPV-related cancer and pre-cancer (median follow-up 11.5 years. There was a statistically significant association between FLG genotype and incident HPV-related cancer and pre-cancer with a hazard ratio, HR = 2.1 (95% confidence intervals, CI: 1.2, 3.7 for FLG mutation carriers vs. wild types.FLG loss-of-function mutations were associated with higher incidence of HPV-related cancers and pre-cancers that are potentially screening and vaccine preventable.

    Alcohol is a risk factor for postmenopausal breast cancer. One of several proposed mechanisms is that alcohol-related breast cancer is caused by increased sex hormone levels. PPARγ inhibits aromatase transcription in breast adipocytes. We reproduced previously found allele-specific effects...... of the wildtype Pro-allele of PPARG Pro12Ala in alcohol related breast cancer. In transiently transfected cells, transcriptional activation by PPARγ and the PPARγ-PGC-1α complex was inhibited by ethanol. PPARγ 12Ala-mediated transcription activation was not enhanced by PGC-1α, resulting in allele......-specific transcription activation by the PPARγ 12Pro-PGC-1α complex. Our results suggest that PPARγ and PGC-1α activity is an important determinant of alcohol related breast cancer....

    Several genetic alterations characteristic of leukemia and lymphoma have been detected in the blood of individuals without apparent hematological malignancies. We analyzed blood-derived sequence data from 2,728 individuals within The Cancer Genome Atlas, and discovered 77 blood-specific mutations in cancer-associated genes, the majority being associated with advanced age. Remarkably, 83% of these mutations were from 19 leukemia/lymphoma-associated genes, and nine were recurrently mutated (DNMT3A, TET2, JAK2, ASXL1, TP53, GNAS, PPM1D, BCORL1 and SF3B1). We identified 14 additional mutations in a very small fraction of blood cells, possibly representing the earliest stages of clonal expansion in hematopoietic stem cells. Comparison of these findings to mutations in hematological malignancies identified several recurrently mutated genes that may be disease initiators. Our analyses show that the blood cells of more than 2% of individuals (5–6% of people older than 70 years) contain mutations that may represent premalignant, initiating events that cause clonal hematopoietic expansion.

    Cancer-related fatigue is one of the most common symptoms experienced by cancer patients, and it diminishes their quality of life. However, there is currently no confirmed standard treatment for cancer-related fatigue, and thus, many patients who suffer cancer-related fatigue seek complementary and alternative medicines such as moxibustion. Moxibustion is one of the most popular therapies in traditional Korean medicine used to manage fatigue. Recent studies have also demonstrated that moxibustion is effective for treating chronic fatigue. However, there is insufficient evidence supporting the effect of moxibustion against cancer-related fatigue. The aim of this study is to assess the efficacy and safety of moxibustion treatment for cancer-related fatigue. A multi-center, three-armed parallel, randomized controlled trial will be conducted. Ninety-six patients with cancer-related fatigue will be recruited from three clinical research centers. They will be randomly allocated to one of three groups in a 1:1:1 ratio. The moxibustion group will receive moxibustion treatment at CV8, CV12, LI4 and ST36. The sham moxibustion group will receive sham moxibustion at non-acupoints. Both the moxibustion and sham moxibustion groups will receive 30-min treatments twice a week for 8 weeks. The usual care group will not receive moxibustion treatment. All participants will be educated via a brochure on how to manage cancer-related fatigue in daily life. The outcome measurements will be evaluated at baseline, week 5, week 9, and week 13 by assessors who are blinded to the group allocation. The primary outcome measure will be the mean change in the average scores of the Brief Fatigue Inventory before and after treatments between groups. The secondary outcome measures will be the mean difference in changes from baseline of the Brief Fatigue Inventory, functional assessments of cancer therapy-fatigue, European Organization for Research and Treatment of Cancer Quality of Life

    Over the last decade, an increasing number of integrative studies on cancer-related genes have been published. Integrative analyses aim to overcome the limitation of a single data type, and provide a more complete view of carcinogenesis. The vast majority of these studies used sample-matched data of gene expression and copy number to investigate the impact of copy number alteration on gene expression, and to predict and prioritize candidate oncogenes and tumor suppressor genes. However, correlations between genes were neglected in these studies. Our work aimed to evaluate the co-alteration of copy number, methylation and expression, allowing us to identify cancer-related genes and essential functional modules in cancer. We built the Integrated Co-alteration network (ICan) based on multi-omics data, and analyzed the network to uncover cancer-related genes. After comparison with random networks, we identified 155 ovarian cancer-related genes, including well-known (TP53, BRCA1, RB1 and PTEN) and also novel cancer-related genes, such as PDPN and EphA2. We compared the results with a conventional method: CNAmet, and obtained a significantly better area under the curve value (ICan: 0.8179, CNAmet: 0.5183). In this paper, we describe a framework to find cancer-related genes based on an Integrated Co-alteration network. Our results proved that ICan could precisely identify candidate cancer genes and provide increased mechanistic understanding of carcinogenesis. This work suggested a new research direction for biological network analyses involving multi-omics data.

    2011-01-01

    With multiple options for urinary diversion after radical cystectomy for bladder cancer that have comparable cancer control and complication rates, health-related quality of life (HRQOL) has become an important consideration. This article reviews the methods for defining HRQOL, the challenges in measuring HRQOL in bladder cancer, and the literature comparing HRQOL after various methods of urinary diversion. Recent contributions include the validation of HRQOL instruments specific to bladder cancer and the publication of several prospective studies measuring HRQOL outcomes after cystectomy and urinary diversion. There is no convincing evidence from existing literature that any particular method of urinary diversion offers superior HRQOL outcomes. Rather, there is growing evidence that good HRQOL can be achieved with patient education and consideration of each patient's clinical and psychosocial situation. Future research should utilize the validated bladder cancer specific HRQOL instruments and perhaps explore the impact of preoperative counseling on postoperative HRQOL. PMID:21826139

    To (i) investigate the characteristics of health-related quality of life and satisfaction with case management and (ii) to identify factors associated with health-related quality of life in cancer survivors. The level of health-related quality of life can reflect treatment efficacy and satisfaction with cancer care. A cross-sectional study design was adopted. Subjects from the outpatient setting of a cancer centre in northern Taiwan were recruited by consecutive sampling. A set of questionnaires were employed, including a background information form, case management service satisfaction survey (CMSS) and The European Quality of Life Scale (EQ-5D). Descriptive statistics were used to examine levels of health-related quality of life and satisfaction with case management. Pearson's correlation was used to identify relationships between treatment characteristics, satisfaction with case management and health-related quality of life. Multiple stepwise regression was used to identify factors associated with health-related quality of life. A total of 252 cancer patients were recruited. The three lowest scores for items of health-related quality of life were mobility, self-care and usual activities. Cancer survivors with higher mobility, less pain and discomfort, and lower anxiety and depression were more likely to have better health-related quality of life. Mobility, pain and discomfort, and anxiety and depression are important predictive factors of high health-related quality of life in cancer survivors. In clinical care, patients' physical mobility, pain and discomfort, and anxiety and depression are important indicators of health-related quality of life. Case managers should include self-care and symptom management into survivorship care plans to improve health-related quality of life during survival after treatment concludes. © 2017 John Wiley & Sons Ltd.

    The author sketches the critical relation between ecology and basic law - critical in more than one sense. He points out the incompatibility of constitutional states and atomic states which is due to constitutional order being jeopardised by nuclear policy. He traces back the continuously rising awareness of pollution and the modern youth movement to their common root i.e. the awakening, the youth movement of the turn of the century. Eventually, he considers an economical, political, and social decentralization as a feasible alternative which would considerably relieve our basic living conditions from the threatening forms of civilization prevailing.

    An unusual county-wide excess of childhood cancers of brain and other nervous tissue in the late 1990s in St Lucie County, Florida, prompted the Florida Department of Health to conduct a case-control study within the county assessing residential chemical exposures. No clear associations were found, but claims were then made that the release of radioactive substances such as strontium 90 from the St Lucie nuclear power station, which began operating in 1976, might have played a role. To test the plausibility of this hypothesis, we extended by 17 years a previous study of county mortality conducted by the National Cancer Institute. Rates of total cancer, leukaemia and cancer of brain and other nervous tissue in children and across all ages in St Lucie County were evaluated with respect to the years before and after the nuclear power station began operation and contrasted with rates in two similar counties in Florida (Polk and Volusia). Over the prolonged period 1950-2000, no unusual patterns of childhood cancer mortality were found for St Lucie County as a whole. In particular, no unusual patterns of childhood cancer mortality were seen in relation to the start-up of the St Lucie nuclear power station in 1976. Further, there were no significant differences in mortality between the study and comparison counties for any cancer in the time period after the power station was in operation. Relative rates for all childhood cancers and for childhood leukaemia were higher before the nuclear facility began operating than after, while rates of brain and other nervous tissue cancer were slightly lower in St Lucie County than in the two comparison counties for both time periods. Although definitive conclusions cannot be drawn from descriptive studies, these data provide no support for the hypothesis that the operation of the St Lucie nuclear power station has adversely affected the cancer mortality experience of county residents

    The incidence of breast cancer continues to rise: 1.7 million women were diagnosed with and 521,000 women died from breast cancer in 2012. This review considers first current treatment options: surgery; radiotherapy; and systemic endocrine, anti-biological, and cytotoxic therapies. Clinical management includes prevention, early detection by screening, treatment with curative intent, management of chronic disease, and palliative control of advanced breast cancer. Next, the potential of novel drugs that target DNA repair, growth factor dependence, intracellular and intercellular signal transduction, and cell cycle are considered. Estrogen-related receptor alpha has attracted attention as a therapeutic target in triple-negative breast cancers with de novo resistance to, and in breast cancers with acquired resistance to, endocrine therapies such as antiestrogens and aromatase inhibitors. Estrogen-related receptor alpha is an orphan receptor and transcription factor. Its activity is regulated by coregulator proteins and posttranslational modification. It is an energy sensor that controls adaptation to energy demand and may facilitate glycolytic metabolism and mitochondrial oxidative respiration in breast cancer cells. Estrogen-related receptor alpha increases breast cancer cell migration, proliferation, and tumor development. It is expressed at high levels in estrogen receptor-negative tumors, and is proposed to activate estrogen-responsive genes in endocrine-resistant tumors. The structures and functions of the ligand-binding domains of estrogen receptor alpha and estrogen-related receptor alpha, their ability to bind estrogens, phytoestrogens, and synthetic ligands, and the effects of ligand agonists, antagonists, and inverse agonists on biological activity, are evaluated. Synthetic ligands of estrogen-related receptor alpha have activity in preclinical models of metabolic disorders, diabetes, osteoporosis, and oncology. The clinical settings in which these novel

    Germline mutations in the BRCA1 gene predispose to the development of breast cancer, exhibiting a specific histological phenotype. Identification of possible hallmarks of these tumors is important for selecting patients for genetic screening and provides inside in carcinogenetic pathways. Since BRCA1-associated breast cancers have pushing borders that prevent them from easily reaching vessels and are often of the medullary (like) type that is known to have a low rate of lympho-vascular invasion (LVI), we hypothesized that absence of LVI could characterize BRCA1 related breast cancer. A population of 68 BRCA1 related invasive breast cancers was evaluated for LVI by an experienced breast pathologist blinded to mutation status, and compared to a control group matched for age, grade and tumor type. LVI was present in 25.0% of BRCA1 related cases, compared to 20.6% of controls (P = 0.54, OR = 1.29, CI 0.58-2.78). LVI is frequent in BRCA1 germline mutation related breast cancers, but seems to occur as often in sporadic controls matched for age, grade and tumor type. Apparently, these hereditary cancers find their way to the blood and lymph vessels despite their well demarcation and often medullary differentiation

    Full Text Available Abstract Background Germline mutations in the BRCA1 gene predispose to the development of breast cancer, exhibiting a specific histological phenotype. Identification of possible hallmarks of these tumors is important for selecting patients for genetic screening and provides inside in carcinogenetic pathways.

    This study examined how stress from cancer affects fruit and vegetable consumption (FVC) in cancer patients and their family caregivers during the year following diagnosis. Colorectal cancer patients and their caregivers (92 dyads) completed questionnaires at two (T1), six (T2), and 12 months post-diagnosis (T3). Individuals reported perceived cancer-related stress (CRS) at T1 and days of adequate FVC at T1 through T3. Both patients and caregivers reported inadequate FVC during the first year post-diagnosis. Latent growth modeling with actor-partner interdependence modeling revealed that, at T1, one's own greater CRS was associated with one's partner having fewer concurrent days of adequate FVC (ps = .01). Patients' greater CRS predicted their own more pronounced rebound pattern in FVC (p = .01); both patients' and caregivers' CRS marginally predicted their partners' change in FVC (p = .09). Findings suggest that perceived stress from cancer hinders FVC around the diagnosis, but motivates positive dietary changes by the end of the first year.

    Researchers have suggested that older adults express less negative emotions. Yet, emotional expression patterns in older and younger breast cancer survivors, have barely been examined. This study aimed to explore types and intensity of negative and positive emotional expression related to the breast cancer experience by younger and older Arab breast cancer survivors. Participants were 20 younger (aged 32-50) and 20 older (aged 51-75) Muslim and Christian Arab breast cancer survivors (stages I-III), currently free of disease. Data were gathered through in-depth semi-structured interviews. Mixed methods analyses were conducted, including: (1) frequency analysis of participants' emotional expressions; (2) content analysis of emotional expressions, categorized according to negative and positive emotions. Three emotional expression modalities were revealed: (1) Succinct versus comprehensive accounts; (2) expression of emotions versus avoidance of emotions; (3) patterns of expression of positive emotions and a sense of personal growth. Younger women provided more detailed accounts about their illness experiences than older women. Older women's accounts were succinct, action-focused, and included more emotion-avoiding expressions than younger women. Understanding the relationships between emotional expression, emotional experience, and cancer survivors' quality of life, specifically of those from traditional communities, is necessary for developing effective psycho-social interventions.

    PURPOSEProlonged and disabling fatigue is prevalent after cancer treatment, but the early natural history of cancer-related fatigue (CRF) has not been systematically examined to document consistent presence of symptoms. Hence, relationships to cancer, surgery, and adjuvant therapy are unclear. PATIENTS AND METHODSA prospective cohort study of women receiving adjuvant treatment for early-stage breast cancer was conducted. Women (n = 218) were enrolled after surgery and observed at end treatment and at 1, 3, 6, 9, and 12 months as well as 5 years. Structured interviews and self-report questionnaires were used to record physical and psychologic health as well as disability and health care utilization. Patients with CRF persisting for 6 months were assessed to exclude alternative medical and psychiatric causes of fatigue. Predictors of persistent fatigue, mood disturbance, and health care utilization were sought by logistic regression.ResultsThe case rate for CRF was 24% (n = 51) postsurgery and 31% (n = 69) at end of treatment; it became persistent in 11% (n = 24) at 6 months and 6% (n = 12) at 12 months. At each time point, approximately one third of the patients had comorbid mood disturbance. Persistent CRF was predicted by tumor size but not demographic, psychologic, surgical, or hematologic parameters. CRF was associated with significant disability and health care utilization. CONCLUSIONCRF is common but generally runs a self-limiting course. Much of the previously reported high rates of persistent CRF may be attributable to factors unrelated to the cancer or its treatment.

    Gastric cancer is the fifth most common malignancy all over the world, and the factors that can affect progress and prognosis of the gastric cancer patients are various, such as TNM stages, invasive depth, and lymph node metastasis ratio. T cell immunity is important component of human immunity system and immunity responding to tumor and dysfunction or imbalance of T cell immunity will lead to serious outcomes for body. T cell immunity includes many different types of cells, CD4+ T cell, CD8+ T cell, memory cell, and so on, and each of them has special function on antitumor response or tumor immune escape which is revealed in lung cancer, colorectal cancer, breast cancer, ovarian cancer, and so on. But its correlation with gastric cancer is not clear. Our review was preformed to explore the relationship between the progress and prognosis of gastric cancer (GC) and T cell immunity. According to recent researches, T cell immunity may have an important role in the progress and prognosis of GCs, but its function is affected by location, category, related molecule, and interaction between the cells, and some effects still are controversial. More researches are needed to clarify this correlation.

    Pancreatic cancer is one of the deadliest cancers with very poor prognosis, and the five-year survival rate of the patients is less than 5% after diagnosis. Kallikrein-related peptidases (KLKs) belong to a serine protease family with 15 members that play important roles in cellular physiological behavior and diseases. The high expression level of KLK7 in pancreatic cancer tissues is considered to be a marker for the poor prognosis of this disease. In this work, we set out to investigate whether KLK7 could be a target for the treatment of pancreatic cancer. Short hairpin RNAs (shRNAs) were designed and constructed in lentivirus to knock down KLK7 in pancreatic cancer cell line PANC-1, and the real time cellular analysis (RTCA) was used to evaluate cell proliferation, migration and invasion abilities. Small molecules inhibiting KLK7 were discovered by computer-aided drug screening and used to inhibit PANC-1 cells. Our results confirmed that KLK7 is significantly up-regulated in pancreatic cancer tissue, and knocking down or inhibiting KLK7 efficiently inhibited the proliferation, migration and invasion of pancreatic cancer cells. This study suggested that KLK7 could be a potential chemotherapy target for treatment of pancreatic cancer, which would provide us a novel strategy for the treatment of this disease. PMID:29560118

    Both of chronic inflammation and abnormal immune in inflammatory bowel disease can induce colon cancer. Previous research showed that cell apoptosis and necrosis become the main source of circulating DNA in the peripheral blood during tumorigenesis that reduced along with methylation degree. However, its role in the process of colitis transforming to colon cancer is not clarified. Drinking 3% DSS was used to establish colitis model, while 3% dextran sodium sulfate (DSS) combined with azo oxidation methane (AOM) intraperitoneal injection was applied to establish colitis related colon cancer model. Circulating DNA and its methylation level in peripheral blood were tested. Morphology observation, HE staining, and p53 and β-catenin expression detection confirmed that drinking 3% DSS and 3% DSS combined with AOM intraperitoneal injection can successfully establish colitis and colitis associated colorectal cancer models. Circulating DNA level in colitis and colon cancer mice increased by gradient compared with control, while significant difference was observed between each other. Circulating DNA methylation level decreased obviously in colitis and colon cancer, and significant difference was observed between each other. Abnormal protein expression, circulating DNA and its methylation level in ulcerative colitis associated colorectal tissues change in gradient, suggesting that circulating DNA and its methylation level can be treated as new markers for colitis cancer transformation that has certain significance to explore the mechanism of human ulcerative colitis canceration.

    Background: Breast cancer is a major public health problem globally. The ongoing epidemiological, socio-cultural and demographic transition by accentuating the associated risk factors has disproportionately increased the incidence of breast cancer cases and resulting mortality in developing countries like India. Early diagnosis with rapid initiation of treatment reduces breast cancer mortality. Therefore awareness of breast cancer risk and a willingness to undergo screening are essential. The objective of the present study was to assess the knowledge and practices relating to screening for breast cancer among women in Delhi. Methods: Data were obtained from 222 adult women using a pretested selfadministered questionnaire. Results: Rates for knowledge of known risk factors of breast cancer were: family history of breast cancer, 59.5%; smoking, 57.7%; old age, 56.3%; lack of physical exercise, 51.9%; lack of breastfeeding, 48.2%; late menopause, 37.4%; and early menarche, 34.7%.

    The objective of this study was to examine associations of symptoms with physical and mental health-related quality of life (HRQOL) in patients with colorectal cancer (CRC) and in patients with lung cancer. Patients with newly diagnosed CRC (n = 3040) or lung cancer (n = 2297) who were participating in the Cancer Care Outcomes Research and Surveillance Consortium study completed surveys on general HRQOL and symptoms. HRQOL was measured by using physical component summary (PCS) and mental component summary (MCS) scores on the Medical Outcomes Study 12-item short-form heath survey. Nonspecific cancer symptoms were measured using items from the European Organization for Research and Treatment of Cancer core quality-of-life questionnaire. Cancer type-specific modules developed by the European Organization for Research and Treatment of Cancer were used to assess CRC-specific and lung cancer-specific symptoms. For both cancer types, linear regression models that were controlled for demographic and clinical information were used to examine correlations of nonspecific and cancer-specific symptoms with PCS and MCS scores. PCS scores for patients with CRC and lung cancer were below the general population norm of 50 (43 and 37, respectively), and MCS scores were at the population norm. For the CRC sample, in the model that included both symptom indices, an increase in nonspecific symptoms was more strongly associated with lower PCS and MCS scores than an increase in CRC-specific symptoms (PCS, standardized coefficient [β] = -0.41 vs -0.09; MCS, β = -0.38 vs -0.08). In a similar model for lung cancer, increases in lung cancer-specific symptoms were more strongly associated with lower PCS scores (β = -0.34 vs -0.20), whereas nonspecific symptoms were more strongly associated with lower MCS scores (β = -0.34 vs -0.14). Symptoms were associated with HRQOL impairments in recently diagnosed patients. Additional supportive care implemented early in cancer care

    Full Text Available Tobacco smoking is a main cause of disease in Switzerland; lung cancer being the most common cancer mortality in men and the second most common in women. Although disease-specific mortality is decreasing in men, it is steadily increasing in women. The four language regions in this country might play a role in this context as they are influenced in different ways by the cultural and social behaviour of neighbouring countries. Bayesian hierarchical spatio-temporal, negative binomial models were fitted on subgroup-specific death rates indirectly standardized by national references to explore age- and gender-specific spatio-temporal patterns of mortality due to lung cancer and other tobacco-related cancers in Switzerland for the time period 1969-2002. Differences influenced by linguistic region and life in rural or urban areas were also accounted for. Male lung cancer mortality was found to be rather homogeneous in space, whereas women were confirmed to be more affected in urban regions. Compared to the German-speaking part, female mortality was higher in the French-speaking part of the country, a result contradicting other reports of similar comparisons between France and Germany. The spatio-temporal patterns of mortality were similar for lung cancer and other tobacco-related cancers. The estimated mortality maps can support the planning in health care services and evaluation of a national tobacco control programme. Better understanding of spatial and temporal variation of cancer of the lung and other tobacco-related cancers may help in allocating resources for more effective screening, diagnosis and therapy. The methodology can be applied to similar studies in other settings.

    Full Text Available Objectives: To investigate community support for government-led policy initiatives to positively influence the food environment, and to identify whether there is a relationship between support for food policy initiatives and awareness of the link between obesity-related lifestyle risk factors and cancer. Methods: An online survey of knowledge of cancer risk factors and attitudes to policy initiatives that influence the food environment was completed by 2474 adults from New South Wales, Australia. The proportion of participants in support of seven food policy initiatives was quantified in relation to awareness of the link between obesity, poor diet, insufficient fruit and vegetable consumption, and physical inactivity with cancer and other health conditions. Results: Overall, policies that involved taxing unhealthy foods received the least support (41.5%. Support was highest for introducing a colour-coded food labelling system (85.9%, restricting claims being made about the health benefits of foods which are, overall, unhealthy (82.6%, displaying health warning labels on unhealthy foods (78.7% and banning unhealthy food advertising that targets children (72.6%. Participants who were aware that obesity-related lifestyle factors are related to cancer were significantly more likely to support food policy initiatives than those who were unaware. Only 17.5% of participants were aware that obesity, poor diet, insufficient fruit and vegetable consumption, and physical inactivity are linked to cancer. Conclusions: There is strong support for all policies related to food labelling and a policy banning unhealthy food advertising to children. Support for food policy initiatives that positively influence the food environment was higher among those who were aware of the link between cancer and obesity-related lifestyle factors than among those who were unaware of this link.

    2011-12-01

    Full Text Available Abstract Background DNA methylation is regarded as a potential biomarker in the diagnosis and treatment of cancer. The relations between aberrant gene methylation and cancer development have been identified by a number of recent scientific studies. In a previous work, we used co-occurrences to mine those associations and compiled the MeInfoText 1.0 database. To reduce the amount of manual curation and improve the accuracy of relation extraction, we have now developed MeInfoText 2.0, which uses a machine learning-based approach to extract gene methylation-cancer relations. Description Two maximum entropy models are trained to predict if aberrant gene methylation is related to any type of cancer mentioned in the literature. After evaluation based on 10-fold cross-validation, the average precision/recall rates of the two models are 94.7/90.1 and 91.8/90% respectively. MeInfoText 2.0 provides the gene methylation profiles of different types of human cancer. The extracted relations with maximum probability, evidence sentences, and specific gene information are also retrievable. The database is available at http://bws.iis.sinica.edu.tw:8081/MeInfoText2/. Conclusion The previous version, MeInfoText, was developed by using association rules, whereas MeInfoText 2.0 is based on a new framework that combines machine learning, dictionary lookup and pattern matching for epigenetics information extraction. The results of experiments show that MeInfoText 2.0 outperforms existing tools in many respects. To the best of our knowledge, this is the first study that uses a hybrid approach to extract gene methylation-cancer relations. It is also the first attempt to develop a gene methylation and cancer relation corpus.

    Full Text Available Abstract Background The 5-year survival rate for breast cancer among Korean women has increased steadily; however, breast cancer remains the leading cause of cancer mortality among women. One-carbon metabolism, which requires an adequate supply of methyl group donors and B vitamins, may affect the prognosis of breast cancer. This aim of this study was to investigate the associations of dietary intake of vitamin B2, vitamin B6 and folate before diagnosis on the prognosis of breast cancer. Methods We assessed the dietary intake using a food frequency questionnaire with 980 women who were newly diagnosed and histopathologically confirmed to have primary breast cancer from hospitals in Korea, and 141 disease progression events occurred. Cox’s proportional hazard regression models were used to estimate the hazard ratio (HR and 95% confidence interval (95% CI adjusting for age, education, recruitment sites, TNM stage, hormone status, nuclear grade and total calorie. Results There was no significant association between any one-carbon metabolism related nutrients (vitamin B2, B6 and folate and the progression of breast cancer overall. However, one-carbon metabolism related nutrients were associated with disease progression in breast cancer patients stratified by subtypes. In ER + and/or PR + breast cancers, no association was observed; however, in ER–/PR– breast cancers, a high intake of vitamin B2 and folate statistically elevated the HR of breast cancer progression (HR = 2.28; 95% CI, 1.20-4.35, HR = 1.84; 95% CI, 1.02-3.32, respectively compared to a low intake. This positive association between the ER/PR status and progression of the disease was profound when the nutrient intakes were categorized in a combined score (Pinteraction = 0.018. In ER–/PR– breast cancers, high combined scores were associated with a significantly poor DFS compared to those belonging to the low score group (HR = 3.84; 95% CI, 1

    Nitrate is a precursor in the endogenous formation of N-nitroso compounds, which are potent animal carcinogens, whereas antioxidant vitamins have been suggested to protect against carcinogenesis. Interestingly, nitrate and antioxidant vitamins stem from the same dietary sources. We investigated whether the intake of nitrate relative to antioxidant vitamins is associated with the risk of breast cancer. A total of 362 breast cancer cases were matched to the 362 controls by age and menopausal status. Dietary intake was assessed using a quantitative food frequency questionnaire with 121 food items by trained interviewers. The nitrate to antioxidant vitamin consumption ratio was then calculated. Conditional logistic regression analysis was used to obtain odds ratios (ORs) and corresponding 95% confidence intervals (CI). Mean intakes of nitrate for cases and controls were 421 mg/day and 424 mg/day, respectively. Intakes of nitrate, nitrate/beta-carotene, nitrate/vitamin C, and nitrate/vitamin E were not associated with breast cancer risk. However, higher breast cancer risk was observed with higher intake of nitrate/folate (OR = 2.03, 95% CI = 1.16-3.54, P for trend = 0.052). Our results suggest that lowering the ratio of nitrate to folate intake may be effective in reducing breast cancer risk.

  16. Depression and Anxiety Symptoms Relate to Distinct Components of Pain Experience among Patients with Breast Cancer

    Directory of Open Access Journals (Sweden)

    Sarah K. Galloway

    2012-01-01

    Full Text Available Breast cancer is a leading cancer diagnosis among women worldwide, with more than 210,000 new cases and 40,000 deaths per year in the United States. Pain, anxiety, and depression can be significant factors during the course of breast cancer. Pain is a complex experience with sensory, affective, and cognitive dimensions. While depression and anxiety symptoms are relatively common among breast cancer patients, little is known about the relation between these psychiatric factors and distinct components of the pain experience. In the present study 60 females presenting to an NCI-designated Cancer Center with newly diagnosed breast cancer completed the Center for Epidemiological Studies 10-item Depression Scale, the State Instrument of the Spielberger State-Trait Anxiety Inventory, and the McGill Pain Questionnaire. Findings indicate that anxiety and depression are common among newly diagnosed breast cancer patients; furthermore, patients experience an appreciable amount of pain even before oncologic treatment starts. State anxiety serves as a predictor of the sensory dimension of the pain experience, whereas depression serves as a predictor of the affective dimension of the pain experience.

  17. Relative and absolute risk models for cancer mortality in ankylosing spondylitis patients

    Muirhead, C.R.; Darby, S.C.

    1989-01-01

    The updated analyses presented in this paper have indicated that, even after allowing for the effects of other variables, the relative risk of all cancers excluding leukaemia and colon cancer among the irradiated spondylitics tails off beyond twenty-five years following exposure. Additionally, the corresponding absolute excess risk also tails off. This is still the only major study to show a wearing off of the radiation-related risk for such a grouping of cancers (although some wearing off has been seen for individual cancers such as bone in other studies). Further analysis of the spondylitic data (Darby, Doll and Smith, 1988) has not found any artificial explanation for the tailing off in risk, such as changes in lifestyle. However, it is noticeable that the dose was delivered to the spondylitics in fractions (see Lewis et al., 1988, table IV) rather than instantaneously, although it is not immediately obvious why this should have affected the temporal pattern of the risk.

    The causal role of work-related exposure to wood dust in the development of sinonasal cancer has long been established by numerous epidemiologic studies. To study molecular changes in these tumors, we analyzed TP53 gene mutations in 358 sinonasal cancer cases with or without occupational exposure...... affected the ORs only slightly. Smoking did not influence the occurrence of TP53 mutation; however, it was associated with multiple mutations (p = 0.03). As far as we are aware, this is the first study to demonstrate a high prevalence of TP53 mutation-positive cases in a large collection of sinonasal...... cancers with data on occupational exposure. Our results indicate that mutational mechanisms, in particular TP53 mutations, are associated with work-related exposure to wood dust in sinonasal cancer....

    Objective: To investigate the prevalence of depression in women with breast cancer and relate it to their health-related quality of life. Methods: The cross-sectional study was conducted at the Imam Khomeini Hospital in Iran between January and December 2009, and comprised 60 women with breast cancer with a mean age of 43.8+-47.12 years. In order to assess the health-related quality of life, the study used the parameters of the Iranian version of the Functional Assessment of Cancer Therapy for Breast Cancer. To identify expressive symptoms, the Beck Depression Inventory was used. General linear model regression and SPSS 14 were used to analyse the data. Results: Significant differences in the prevalence of depression between treatment types was found. The presence of depression was significantly correlated with poorer overall health-related quality of life and the four subscales of the protocol. The patients reported statistically significant effects of depression in the overall category (p= 0.001). Participants with depression were more likely to have a poorer overall health-related quality of life, the exception being the social/family well-being subscale. Conclusions: Depression affects health-related quality of life in breast cancer patients. Although further studies are necessary to confirm our findings, but our results emphasise the necessity for better mental health strategies for such patients. (author)

    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.

  1. Adjusting a cancer mortality-prediction model for disease status-related eligibility criteria

    2011-05-01

    Full Text Available Abstract Background Volunteering participants in disease studies tend to be healthier than the general population partially due to specific enrollment criteria. Using modeling to accurately predict outcomes of cohort studies enrolling volunteers requires adjusting for the bias introduced in this way. Here we propose a new method to account for the effect of a specific form of healthy volunteer bias resulting from imposing disease status-related eligibility criteria, on disease-specific mortality, by explicitly modeling the length of the time interval between the moment when the subject becomes ineligible for the study, and the outcome. Methods Using survival time data from 1190 newly diagnosed lung cancer patients at MD Anderson Cancer Center, we model the time from clinical lung cancer diagnosis to death using an exponential distribution to approximate the length of this interval for a study where lung cancer death serves as the outcome. Incorporating this interval into our previously developed lung cancer risk model, we adjust for the effect of disease status-related eligibility criteria in predicting the number of lung cancer deaths in the control arm of CARET. The effect of the adjustment using the MD Anderson-derived approximation is compared to that based on SEER data. Results Using the adjustment developed in conjunction with our existing lung cancer model, we are able to accurately predict the number of lung cancer deaths observed in the control arm of CARET. Conclusions The resulting adjustment was accurate in predicting the lower rates of disease observed in the early years while still maintaining reasonable prediction ability in the later years of the trial. This method could be used to adjust for, or predict the duration and relative effect of any possible biases related to disease-specific eligibility criteria in modeling studies of volunteer-based cohorts.

    We examined whether (1) fear of cancer recurrence was related to lower health-related quality of life and (2) perceived growth moderated the link between fear of recurrence and health-related quality of life. About 292 adolescent and young adult cancer survivors (diagnosed with cancer at ages 15-34) completed a cross-sectional survey. Fear of recurrence was related to poorer physical and mental health-related quality of life. The negative association between fear of recurrence and mental health-related quality of life was moderated by perceived growth. Fostering perceived growth may mitigate the adverse associations of fear of recurrence and health-related quality of life.

    Aim To determine whether breast cancer survivors (BCS) at work following the diagnosis and/or treatment of breast cancer, in a rapidly developing country such as China experience similar to return to work challenges as reported in nations with established return to work (RTW) policy and procedures for employees with cancer. Methods Semi-structured interviews were conducted with 16 BCS who returned to work following diagnosis and/or primary cancer treatment. An Interpretative Phenomenological Analysis was used to investigate responses. Results Three recurring themes emerged: (1) challenges at work related to residual effects of diagnosis and/or primary treatment; (2) positive and negative responses from employers and/or supervisors; and (3) positive and negative responses from co-workers/colleagues. Although several participants experienced a high level of workplace support, there was a subgroup that did report challenges related to symptom burden, cognitive limitations, and both positive and negative responses by employers and co-workers were reported. Conclusions Findings indicate similar challenges in BCS who RTW during and/or following cancer treatment in both rapidly developing and developed nations. Results suggest that regardless of the existence of workplace policies and practices related to RTW for workers with a history of cancer, a subgroup of BCS experience similar challenges when returning to work. These findings highlight the international nature of RTW challenges and suggest the need for more global efforts to develop and evaluate workplace interventions to assist with these similarities.

  7. Alternative Splicing in Adhesion- and Motility-Related Genes in Breast Cancer

    2016-01-01

    Full Text Available Breast cancer is the most common tumor and the second leading cause of cancer death among woman, mainly caused by the metastatic spread. Tumor invasiveness is due to an altered expression of adhesion molecules. Among them, semaphorins are of peculiar interest. Cancer cells can manipulate alternative splicing patterns to modulate the expression of adhesion- and motility-related molecules, also at the isoform level. In this study, combining RNA-Sequencing on MCF-7 to targeted experimental validations—in human breast cell lines and breast tumor biopsies—we identified 12 new alternative splicing transcripts in genes encoding adhesion- and motility-related molecules, including semaphorins, their receptors and co-receptors. Among them, a new SEMA3F transcript is expressed in all breast cell lines and breast cancer biopsies, and is translated into a new semaphorin 3F isoform. In silico analysis predicted that most of the new putative proteins lack functional domains, potentially missing some functions and acquiring new ones. Our findings better describe the extent of alternative splicing in breast cancer and highlight the need to further investigate adhesion- and motility-related molecules to gain insights into breast cancer progression.

    Exercise is recommended for cancer patients to reduce fatigue and improve quality of life. This study's aim is to evaluate the influence of an exergaming protocol on cancer-related fatigue, muscle fatigue, and muscle strength in cancer patients. We conducted a quasi-experimental control study using exergaming in all groups through an Xbox360 Kinect™ console, two to three times per week, for 20 sessions. Three groups were created: cancer patients in chemotherapy and/or radiotherapy group (CRG; n:15), cancer patients after chemotherapy and/or radiotherapy (CAG; n:15), and a control group (CG; n:15). They were assessed for cancer-related fatigue using the fatigue subscale of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire. To assess dorsiflexor and plantar flexor muscle functioning, we used median frequency (MDF) of the surface electromyography and muscle strength using a dynamometer. The assessments were performed preintervention (EV0), after 10 sessions (EV1), and after 20 sessions (EV2). With an exergaming protocol, CRG and CAG showed a reduction in related fatigue compared with CG (P fatigue, including muscle fatigue, and increasing muscle strength in patients' legs.

    Despite the growing importance of cancer and return-to-work issues in occupational rehabilitation literature in the last decade, academic discussion is largely limited to survivors' perspectives and some exploratory studies from the employer side. This paper applies two classic theoretical models-Theory of Planned Behavior and Social Cognitive Theory-and key measures from previous studies to identify explicit relationships that explain employer factors to hire and retain cancer survivors. Data were collected from online surveys with senior management executives and senior human resource specialists from various organizations in Singapore, with a total of 145 responses. The 72-item survey instrument included a series of independent variables: (1) Attitudes toward cancer and cancer survivors; (2) Employers' efficacy; (3) Perceived moral obligation; (4) Employers' experience; (5) Outcome expectations; (6) Employment situation; (7) Social norms; and (8) Incentives, and dependent variables: (a) Employers' intention to hire cancer survivors; and (b) Employers' intention to retain cancer survivors. Regression analyses showed that the top three factors related to employers' intention to retain cancer survivors are perceived moral obligations (β = .39, p employment situation (β = .17, p Employers' efficacy was associated with intention to hire (β = .22, p employer and an employee when it comes to retaining cancer survivors and government incentives for hiring cancer survivors in the workforce. The present study provided an avenue to implement the proposed model-a potential study framework for the management of cancer survivors at work. Findings revealed that different messages should be tailored to employers toward hiring and retention issues and provided useful guidelines for employer education materials.

    Approximately 200,000 women are diagnosed with breast cancer in the U.S. every year. These patients commonly suffer from oral complications of their cancer therapy. The purpose of this study was to assess dental hygienists' knowledge and professional practice related to providing care for breast cancer patients. A pre-tested 43-item survey was mailed to a random sample of 10% of all licensed dental hygienists in the state of Michigan (n=962). The survey assessed the respondents' knowledge of potential oral complications of breast cancer treatments as well as their professional practices when treating patients with breast cancer. After 2 mailings, the response rate was 37% (n=331). Descriptive and inferential analyses were conducted using SAS. Many dental hygienists were unaware of the recommended clinical guidelines for treating breast cancer patients and lacked specific knowledge concerning the commonly prescribed anti-estrogen medications for pre-and postmenopausal breast cancer patients. Over 70% of the respondents indicated they were unfamiliar with the AI class of medications. Only 13% of dental hygienists correctly identified the mechanism of action of anti-estrogen therapy. Dental hygienists reported increased gingival inflammation, gingival bleeding, periodontal pocketing, xerostomia and burning tissues in patients receiving anti-estrogen therapies. Less than 10% believed that their knowledge of breast cancer treatments and the potential oral side effects is up to date. Results indicate a need for more education about the oral effects of breast cancer therapies and about providing the best possible care for patients undergoing breast cancer treatment.

    There is limited evidence for the association between dietary pattern and quality of life among breast cancer survivors. We examined the association between dietary patterns and health-related quality of life (HRQoL) among Korean breast cancer survivors. Our study included a total of 232 women, aged 21 to 79 years, who had been diagnosed with stage I to III breast cancer and who underwent breast cancer surgery at least 6 months prior to our baseline evaluation. We assessed HRQoL using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and the Quality of Life Questionnaire Breast Cancer Module 23 (QLQ-BR23). We conducted a factor analysis to identify the major dietary patterns and used a generalized linear model to obtain the least squares mean (LS mean) and 95% confidence interval (CI) for HRQoL according to the dietary pattern scores. We identified 2 major dietary patterns: the Healthy dietary pattern and the Western dietary pattern. We found that breast cancer survivors who had higher Healthy dietary pattern scores tended to have lower dyspnea scores but higher insomnia scores, compared to breast cancer survivors with lower Healthy dietary pattern scores. For dyspnea, the LS mean (95% CI) was 8.86 (5.05-15.52) in the bottom quartile and 2.87 (1.62-5.08) in the top quartile (p for trend = 0.005). This association was limited to survivors with stage I for dyspnea or survivors with stage II or III for insomnia. Healthy dietary patterns were associated with better scores for dyspnea but worse scores for insomnia among breast cancer survivors. Other components of EORTC QLQ did not vary by dietary patterns overall, but they warrant further investigation for subgroups of breast cancer survivors.

  13. Dietary factors and cancer chemoprevention: An overview of obesity-related malignancies

    Full Text Available Obesity is a growing health problem in developed nations and in countries that are in the process of westernization like India. Obesity is linked with several health disorders such as hypertension and cardiovascular diseases, Type 2 diabetes, dyslipidemia and certain cancers. Currently, obesity-related malignancies, e.g., cancers of the breast, prostate and colon are the leading cancers in the industrialized societies. An increased amount of fat or adipose tissue in an overweight or obese person probably influences the development of cancer by releasing several hormone-like factors or adipokines. The majority of adipokines are pro-inflammatory, which promote pathological conditions like insulin resistance and cancer. On the other hand, many recent studies have shown that adiponectin, an anti-inflammatory adipokine, has anti-cancer and insulin-sensitizing effects. Adiponectin exerts its physiological functions chiefly by activation of AMP kinase via adiponectin receptors. Interestingly, several fruits and vegetables may contain adiponectin-like molecules or may increase the biosynthesis of adiponectin in our body. Studies on adiponectin analogues or adiponectin receptor agonists are a promising area of cancer chemoprevention research. In general, fruits and vegetables contain various dietary substances such as vitamins, minerals (like calcium and selenium, fiber and phytochemicals or phenolic compounds (like flavonoids and vanilloids, which may act as anti-cancer agents. Similarly, several dietary constituents including phytochemicals may have anti-obesity effects. Consumption of such dietary compounds along with caloric restriction and physical activity may be helpful in preventing obesity-related cancers. For this review article, we searched PubMed primarily to get the relevant literature.

    Organochlorine insecticides have been studied extensively in relation to breast cancer incidence, and results from two meta-analyses have been null for late-life residues, possibly due to measurement error. Whether these compounds influence survival remains to be fully explored. We examined associations between organochlorine insecticides [p,p'-DDT (dichlorodiphenyltrichloroethane), its primary metabolite, p,p'-DDE, and chlordane] assessed shortly after diagnosis and survival among women with breast cancer. A population-based sample of women diagnosed with a first primary invasive or in situ breast cancer in 1996-1997 and with available organochlorine blood measures (n = 633) were followed for vital status through 2011. After follow-up of 5 and 15 years, we identified 55 and 189 deaths, of which 36 and 74, respectively, were breast cancer-related. Using Cox regression models, we estimated the multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for lipid-adjusted organochlorine concentrations with all-cause and breast cancer-specific mortality. At 5 years after diagnosis, the highest tertile of DDT concentration was associated with all-cause (HR = 2.19; 95% CI: 1.02, 4.67) and breast cancer-specific (HR = 2.72; 95% CI: 1.04, 7.13) mortality. At 15 years, middle tertile concentrations of DDT (HR = 1.42; 95% CI 0.99, 2.06) and chlordane (HR = 1.42; 95% CI: 0.94, 2.12) were modestly associated with all-cause and breast cancer-specific mortality. Third tertile DDE concentrations were inversely associated with 15-year all-cause mortality (HR = 0.66; 95% CI: 0.44, 0.99). This is the first population-based study in the United States to show that DDT may adversely impact survival following breast cancer diagnosis. Further studies are warranted given the high breast cancer burden and the ubiquity of these chemicals. © 2015 UICC.

    To assess the effectiveness and safety of Chinese herbal medicine for the treatment of cancer-related fatigue. We systematically searched seven electronic databases and two trial registries for randomized clinical trials of Chinese herbal medicine for cancer-related fatigue. Two authors independently extracted data and assessed the methodological quality of the included trials using the Cochrane risk of bias tool. Data were synthesized using RevMan 5.2 software. A total of 10 trials involving 751 participants with cancer-related fatigue were identified and the methodological quality of the included trials was generally poor. Chinese herbal medicine used alone or in combination with chemotherapy or supportive care showed significant relief in cancer-related fatigue compared to placebo, chemotherapy or supportive care based on single trials. Chinese herbal medicine plus chemotherapy or supportive care was superior to chemotherapy or supportive care in improving quality of life. Data from one trial demonstrated Chinese herbal medicine exerted a greater beneficial effect on relieving anxiety but no difference in alleviating depression. Seven trials reported adverse events and no severe adverse effects were found in Chinese herbal medicine groups. The findings from limited number of trials suggest that Chinese herbal medicine seems to be effective and safe in the treatment of cancer-related fatigue. However, the current evidence is insufficient to draw a confirmative conclusion due to the poor methodological quality of included trials. Thus, conducting rigorously designed trials on potential Chinese herbal medicine is warranted. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Many patients near death report an interest in knowing their prognoses. Patients' awareness of disease status may lead to more appropriate care and maintained or improved quality of life. However, it is not known whether advanced cancer patients' awareness of disease status is associated with patients' quality of life. We aimed to examine the effect of patients' awareness of disease status on the health-related quality of life (HRQOL) among advanced cancer patients undergoing palliative chemotherapy. In this prospective cohort study, patients were followed-up at 4-6 weeks and 2-3 months after the initial palliative chemotherapy. Patients' awareness of disease status, and demographic and clinical characteristics were assessed at baseline, and depression and anxiety using the Hospital Anxiety and Depression Scale (HADS) and HRQOL using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) were assessed three times. In total, 100 patients with advanced cancer starting palliative chemotherapy were recruited from two tertiary university hospitals and from the Korea National Cancer Center. Patients with advanced cancer undergoing palliative chemotherapy experienced deteriorated HRQOL. Of these, the patients who were aware of their disease status as incurable had significantly higher role (p=0.002), emotional (p=0.025), and social functioning (p=0.002), and lower fatigue (p=0.008), appetite loss (p=0.039), constipation (p=0.032), financial difficulties (p=0.019), and anxiety (p=0.041) compared with patients unaware of disease status. Our findings demonstrate the importance of patients' awareness of disease status to HRQOL.

    Cancer-related fatigue (CrF) is the most common and disruptive symptom experienced by cancer survivors. We aimed to develop a theory-based, interactive Web-based intervention designed to facilitate self-management and enhance coping with CrF following cancer treatment. The aim of our study was to outline the rationale, decision-making processes, methods, and findings which led to the development of a Web-based intervention to be tested in a feasibility trial. This paper outlines the process and method of development of the intervention. An extensive review of the literature and qualitative research was conducted to establish a therapeutic approach for this intervention, based on theory. The psychological principles used in the development process are outlined, and we also clarify hypothesized causal mechanisms. We describe decision-making processes involved in the development of the content of the intervention, input from the target patient group and stakeholders, the design of the website features, and the initial user testing of the website. The cocreation of the intervention with the experts and service users allowed the design team to ensure that an acceptable intervention was developed. This evidence-based Web-based program is the first intervention of its kind based on self-regulation model theory, with the primary aim of targeting the representations of fatigue and enhancing self-management of CrF, specifically. This research sought to integrate psychological theory, existing evidence of effective interventions, empirically derived principles of Web design, and the views of potential users into the systematic planning and design of the intervention of an easy-to-use website for cancer survivors. ©Teresa Corbett, Jane C Walsh, AnnMarie Groarke, Rona Moss-Morris, Eimear Morrissey, Brian E McGuire.

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

    Understanding the preferred sources of health-related information among patients with cancer is essential for designing successful cancer education and prevention strategies. However, little is known about health-related information-seeking practices among patients living in low- and middle-income countries. We studied the preferred sources of health-related information among Mexican patients with cancer and explored which factors influence these choices. The health-related information-seeking practices among patients with cancer treated at a public hospital in Mexico City were evaluated using questions from the Spanish Version of the Health Information National Trends Survey. The characteristics of patients who sought health-related information, and of those who chose the internet as their preferred source of information, were analyzed. Fisher's exact test and logistic regression were used for statistical analyses. One hundred forty-eight patients answered the survey (median age 60 years, 70% female), of which 88 (59%) had sought for health-related information. On multivariate analysis, the only characteristic associated with lower odds of seeking health-related information was increasing age (OR 0.93, 95% CI 0.90-0.97). Sixty-one respondents (69%) listed the internet as their preferred source of health-related information. On multivariate analysis, only being of the female gender (OR 4.9, 95% CI 1.3-18.3) was related with higher odds of preferring other sources of information over the internet. Among Mexican patients with cancer, the Internet is the most widely used information source. Older age was the characteristic most strongly associated with not seeking health-related information, while being female was strongly associated with preferring other sources of information over the Internet.

  2. Carcinogenic Air Toxics Exposure and Their Cancer-Related Health Impacts in the United States.

    Full Text Available Public health protection from air pollution can be achieved more effectively by shifting from a single-pollutant approach to a multi-pollutant approach. To develop such multi-pollutant approaches, identifying which air pollutants are present most frequently is essential. This study aims to determine the frequently found carcinogenic air toxics or hazardous air pollutants (HAPs combinations across the United States as well as to analyze the health impacts of developing cancer due to exposure to these HAPs. To identify the most commonly found carcinogenic air toxics combinations, we first identified HAPs with cancer risk greater than one in a million in more than 5% of the census tracts across the United States, based on the National-Scale Air Toxics Assessment (NATA by the U.S. EPA for year 2005. We then calculated the frequencies of their two-component (binary, and three-component (ternary combinations. To quantify the cancer-related health impacts, we focused on the 10 most frequently found HAPs with national average cancer risk greater than one in a million. Their cancer-related health impacts were calculated by converting lifetime cancer risk reported in NATA 2005 to years of healthy life lost or Disability-Adjusted Life Years (DALYs. We found that the most frequently found air toxics with cancer risk greater than one in a million are formaldehyde, carbon tetrachloride, acetaldehyde, and benzene. The most frequently occurring binary pairs and ternary mixtures are the various combinations of these four air toxics.

    Public health protection from air pollution can be achieved more effectively by shifting from a single-pollutant approach to a multi-pollutant approach. To develop such multi-pollutant approaches, identifying which air pollutants are present most frequently is essential. This study aims to determine the frequently found carcinogenic air toxics or hazardous air pollutants (HAPs) combinations across the United States as well as to analyze the health impacts of developing cancer due to exposure to these HAPs. To identify the most commonly found carcinogenic air toxics combinations, we first identified HAPs with cancer risk greater than one in a million in more than 5% of the census tracts across the United States, based on the National-Scale Air Toxics Assessment (NATA) by the U.S. EPA for year 2005. We then calculated the frequencies of their two-component (binary), and three-component (ternary) combinations. To quantify the cancer-related health impacts, we focused on the 10 most frequently found HAPs with national average cancer risk greater than one in a million. Their cancer-related health impacts were calculated by converting lifetime cancer risk reported in NATA 2005 to years of healthy life lost or Disability-Adjusted Life Years (DALYs). We found that the most frequently found air toxics with cancer risk greater than one in a million are formaldehyde, carbon tetrachloride, acetaldehyde, and benzene. The most frequently occurring binary pairs and ternary mixtures are the various combinations of these four air toxics. Analysis of urban and rural HAPs did not reveal significant differences in the top combinations of these chemicals. The cumulative annual cancer-related health impacts of inhaling the top 10 carcinogenic air toxics included was about 1,600 DALYs in the United States or 0.6 DALYs per 100,000 people. Formaldehyde and benzene together contribute nearly 60 percent of the total cancer-related health impacts. Our study shows that although there are many

    Current knowledge about Chornobyl-related thyroid cancer risks comes from ecological studies based on grouped doses, case-control studies, and studies of prevalent cancers. To address this limitation, we evaluated the dose-response relationship for incident thyroid cancers using measurement-based individual iodine-131 (I-131) thyroid dose estimates in a prospective analytic cohort study. The cohort consists of individuals radioactivity measurements taken within 2 months after the accident, environmental transport models, and interview data. Excess radiation risks were estimated using Poisson regression models. Sixty-five incident thyroid cancers were diagnosed during the second through fourth screenings and 73,004 person-years (PY) of observation. The dose-response relationship was consistent with linearity on relative and absolute scales, although the excess relative risk (ERR) model described data better than did the excess absolute risk (EAR) model. The ERR per gray was 1.91 [95% confidence interval (CI), 0.43-6.34], and the EAR per 10⁴ PY/Gy was 2.21 (95% CI, 0.04-5.78). The ERR per gray varied significantly by oblast of residence but not by time since exposure, use of iodine prophylaxis, iodine status, sex, age, or tumor size. I-131-related thyroid cancer risks persisted for two decades after exposure, with no evidence of decrease during the observation period. The radiation risks, although smaller, are compatible with those of retrospective and ecological post-Chornobyl studies.

    Cancer-related direct-to-consumer advertising (DTCA) is controversial because cancer treatment is complex and entails more risks and costs than typical treatments that are advertised for other conditions. Drawing from the Structural Influence Model of Communication, this study explores communication inequalities in DTCA exposure across social determinants among a population-based sample of 2013 patients diagnosed with breast, prostate, or colorectal cancers. Three survey items assessed patients' frequency of encountering ads concerning treatment alternatives for cancer, dealing with side effects of treatment, and doctors or hospitals offering services for cancer following their diagnosis. The analysis showed that overall exposure to DTCA in this study population was modest (median was once per week). Breast cancer patients reported significantly higher exposure to all three ad categories and overall DTCA exposure than prostate and colorectal cancer patients. Older patients consistently reported lower overall exposure to DTCA across the three cancer types. Other significant correlates included ethnicity (higher exposures among African American prostate cancer patients vs. White; lower exposures in Hispanic colorectal cancer patients vs. White) and cancer stage (higher exposures in Stage IV prostate cancer patients vs. Stages 0-II). Education level did not predict patients' DTCA exposure. The implications of these observed inequalities in DTCA exposure on cancer outcomes are discussed.

    BRCA mutation-associated (BRCAmut) breast cancer represents a heterogeneous group displaying certain molecular features. Claudin-low breast cancers (CLBC) overlap with characteristics of BRCAmut tumors; therefore, we have investigated whether these are identical subtypes. Using public gene expression data, CLDN, CDH1, 9-cell line claudin-low predictor (9CLCLP) and PAM50 expression was evaluated in BRCAmut and BRCA wild-type (BRCAwt) breast cancer cases focusing on their possible overlap with the CLBC subtype. A separate formalin-fixed, paraffin-embedded (FFPE) cohort of 22 BRCAmut and 19 BRCAwt tumor tissues was used for immunohistochemical examination of AR, CD24, CD44, CK5/6, claudin-1, -3, -4 and -7, E-cadherin, EGFR, estrogen receptor (ER), EZH2, HER2, Ki67, p53, progesterone receptor (PgR) and vimentin expression. In the data sets, CLDN1 (ROC = 0.785, p < 0.001), CDH1 (ROC = 0.785, p < 0.001), CLDN7 (ROC = 0.723, p < 0.001), CLDN3 (ROC = 0.696, p = 0.020) and CLDN4 (ROC = 0.685, p = 0.027) were expressed at higher level in BRCAmut than BRCAwt tumor tissue. The PAM50 subtype differed from the assigned immunohistochemistry (IHC)-based subtype in 30%. Based on accessible 9CLCLP predictor genes, BRCAmut breast cancer does not display the claudin-low phenotype. Utilizing FFPE samples, claudins were evidently expressed in both BRCAmut and BRCAwt cases. However, at the protein level, only claudin-3 expression was higher in BRCAmut tumors, while claudin-1, -4 and -7 and E-cadherin expression was lower compared to BRCAwt cases. A CD24low/CD44high phenotype was found in BRCAmut tumors upon comparison with BRCAwt cases (p < 0.001 and p = 0.001, respectively). There is a prominent correlation between the genes under focus herein and BRCA mutation status. BRCAmut tumors bear stem cell characteristics displaying a distinct cell adhesion molecule profile characterized by high expression of CDH1 and CLDN4 according to public gene expression data set analysis, and higher

    In the United States, prostate cancer is the most common type of cancer in men after skin cancer. There is a paucity of research devoted to the types of prostate cancer information available on social media outlets. YouTube TM is a widely used video sharing website, which is emerging as commonplace for information related to health. The purpose of this study was to describe the most widely viewed YouTube TM videos related to prostate cancer. The 100 videos were watched a total of 50,278,770 times. The majority of videos were uploaded by consumers (45.0%) and medical or government professionals (30%). The purpose of most videos (78.0%) was to provide information, followed by discussions of prostate cancer treatment (51%) and prostate-specific antigen testing and routine screening (26%). All videos uploaded by medical and government professionals and 93.8% of videos uploaded by news sources provided information compared with about two thirds of consumer and less than one half of commercial and advertisement videos (p < .001). As society becomes increasingly technology-based, there is a need to help consumers acquire knowledge and skills to identify credible information to help inform their decisions. © The Author(s) 2016.

    Full Text Available The tumor suppressor gene, BRCA1 has been conferred to increase the susceptibility to breast cancer in younger women. This work studied the expression of BRCA1 (mRNA in women with breast cancer in relation to other prognostic parameters such as histological type and grade of cancer, hormone receptor status, human epidermal growth factor receptor 2 (HER2/neu and CA15-3. Thirty patients with positive family history of breast cancer and a control group of 20 healthy subjects were also included for the study. Ribonucleic acid (RNA extraction from breast cancer tissues was done (considered suitable for RNA extraction if 70% or more of the tissue section contained tumor and was followed by real-time reverse transcription polymerase chain reaction. BRCA1 expression was assessed and correlated with age, histological type and grade of breast cancer, estrogen and progesterone receptor (ER, PR status, HER2/neu expression and CA15-3 levels. The mean age of patients was 54.8 ± 10.49 years. Of the 30 breast cancer cases studied, the majority (77% was of high histological grade and the most common histological type was infiltrating ductal carcinoma (20 cases. ER expression was positive in 53.3% of breast cancers, while PR expression was positive in 50% of cancers. BRCA1 mRNA was found in 6 patient samples (20% of the breast cancer patients while the remaining 24 patients (80% showed negative BRCA1 mRNA expression as well as the control group. A positive significant relationship was demonstrated between BRCA1 (mRNA expression and high histological grade, negative estrogen and progesterone receptor status, and high levels of serum CA15-3. A significant negative correlation was found between BRCA1 mRNA expression and age (r = −0.683; p < 0.01. The study demonstrated lack of BRCA1 gene expression (mRNA in the majority of breast cancer cases and confirmed the relationship between BRCA1 expression and parameters that determine poor prognosis in breast cancer.

    The relationship between the pharmaceutical industry and cancer patient groups has been the subject of much scrutiny and skepticism, and some high-profile negative media coverage has focused attention on some of the problematic aspects of the relationship. Both the pharmaceutical industry and cancer patient groups have made an effort in recent years to improve the transparency and openness of their relations, specifically with regard to the financial support offered by pharmaceutical companies to patient groups. The objectives of this survey were to benchmark perceptions held by different stakeholder groups about current relationships between cancer patient groups and pharmaceutical companies in Europe, and to explore opinions about ways in which partnerships between patient groups and pharmaceutical companies could evolve to the benefit of cancer patients. The survey was conducted using a structured questionnaire that contained a combination of matrix, scaled, and open-ended questions. The questionnaire was developed based on a literature search and the findings from ten in-depth interviews conducted with policy makers and advocates working at an EU level. Telephone interviews were carried out using a structured questionnaire with a convenience sample of 161 policy makers, cancer healthcare group representatives, and cancer patient group leaders from France, Germany, Hungary, Italy, Latvia, the Netherlands, Poland, Portugal, Romania, Spain, Sweden, and the UK. The interviews took place in the relevant language of the country. The current relationship between the pharmaceutical industry and cancer patient groups in Europe is generally viewed as positive, but it is also viewed as being unequal, not transparent enough, and not sufficiently patient-centric. There is broad agreement that cancer patient groups can help companies identify unmet needs and contribute to the development of innovative medicines; however, there is some concern about cancer patients

    Exposure to excessive heat kills more people than any other weather-related phenomenon, aggravates chronic diseases, and causes direct heat illness. Strong associations between extreme heat and health have been identified through increased mortality and hospitalizations and there is growing evidence demonstrating increased emergency department visits and demand for emergency medical services (EMS). The purpose of this study is to build on an existing regional assessment of mortality and hospitalizations by analyzing EMS demand associated with extreme heat, using calls as a health metric, in King County, Washington (WA), for a 6-year period. Relative-risk and time series analyses were used to characterize the association between heat and EMS calls for May 1 through September 30 of each year for 2007-2012. Two EMS categories, basic life support (BLS) and advanced life support (ALS), were analyzed for the effects of heat on health outcomes and transportation volume, stratified by age. Extreme heat was model-derived as the 95th (29.7 °C) and 99th (36.7 °C) percentile of average county-wide maximum daily humidex for BLS and ALS calls respectively. Relative-risk analyses revealed an 8 % (95 % CI: 6-9 %) increase in BLS calls, and a 14 % (95 % CI: 9-20 %) increase in ALS calls, on a heat day (29.7 and 36.7 °C humidex, respectively) versus a non-heat day for all ages, all causes. Time series analyses found a 6.6 % increase in BLS calls, and a 3.8 % increase in ALS calls, per unit-humidex increase above the optimum threshold, 40.7 and 39.7 °C humidex respectively. Increases in "no" and "any" transportation were found in both relative risk and time series analyses. Analysis by age category identified significant results for all age groups, with the 15-44 and 45-64 year old age groups showing some of the highest and most frequent increases across health conditions. Multiple specific health conditions were associated with increased risk of an EMS call including abdominal

    Full Text Available Abstract Background Colorectal cancer is a major public health problem in Malaysia. However, it is also one of the most treatable cancers, resulting in significant numbers of survivors. Therefore, the impact of surviving treatment for colorectal cancer on health related quality of life is important for the patients, clinicians and policy makers, and may differ in different cultures and populations. The aim of this study was to validate the Malaysian versions of the European Organization for Research and Treatment of Cancer quality of life instruments among colorectal cancers patients. Methods/design This is a cross sectional multi centre study. Three hospitals were included, the University of Malaya Medical Centre, the Universiti Kebangsaan Malaysia Medical Centre and Hospital Tuanku Jaafar Seremban. Malaysian citizens and permanent residence were studied and demographic and clinical information obtained from hospital records. The European Organization for Research and Treatment of Cancer Quality of life Core 30, colorectal cancer CR29, and the colorectal cancer liver metastasis LMC 21 were used and an observer assessment of performance obtained with the Karnofsky Performance Scale. Questionnaires were translated into three most commonly spoken languages in Malaysia (Bahasa Malaysia, Chinese and Tamil, then administered, scored and analyzed following the developers’ guidelines.

    Central European mortality rates for cancer sites related to tobacco and alcohol have increased rapidly in recent decades. From a public health point of view, it is of considerable interest to know whether these past increases in cancer mortality will continue into the future. Cancer mortality rates for the period 1965-1994 in Bulgaria, Czech Republic and Slovakia (analysed together), Hungary, Poland, and Romania were analysed for cancers of the larynx, oral cavity and pharynx, oesophagus, bladder, kidney, and pancreas. Using a Bayesian age-period-cohort approach, we have calculated smoothed observed rates. The effects of period and cohort were extrapolated to estimate mortality projections for 1995-99, 2004-09, and 2005-09. Mortality rates for all sites are projected to increase in most countries. Hungary has the highest projected rates for most sites, and particularly rapid increases are expected for cancers of the oral cavity and pharynx and of the larynx in Hungarian men. The smoothed 1990-94 male mortality rates for these two sites of 16. 32/100,000 and 8.70/100,000, respectively, are projected to reach 35. 17/100,000 for cancer of the oral cavity and pharynx and 14.12/100, 000 for cancer of the larynx by the period 2000-04. For kidney cancer, former Czechoslovakia has the highest observed and projected mortality rates. The smoothed 1990-94 rate of 8.37/100,000 is expected to increase 24% to 10.38/100,000 by 2000-04. Our results indicate that further increases may be expected on top of the already high cancer mortality levels in Central Europe. Policies to reduce alcohol consumption and prevent smoking in younger generations are necessary to reduce mortality as these cohorts age. Copyright 2000 Wiley-Liss, Inc.

    Family history (FH) of pancreatic cancer (PC) has been associated with an increased risk of PC, but little is known regarding the role of inherited/environmental factors or that of FH of other comorbidities in PC risk. We aimed to address these issues using multiple methodological approaches. Case-control study including 1431 PC cases and 1090 controls and a reconstructed-cohort study (N = 16 747) made up of their first-degree relatives (FDR). Logistic regression was used to evaluate PC risk associated with FH of cancer, diabetes, allergies, asthma, cystic fibrosis and chronic pancreatitis by relative type and number of affected relatives, by smoking status and other potential effect modifiers, and by tumour stage and location. Familial aggregation of cancer was assessed within the cohort using Cox proportional hazard regression. FH of PC was associated with an increased PC risk [odds ratio (OR) = 2.68; 95% confidence interval (CI): 2.27-4.06] when compared with cancer-free FH, the risk being greater when ≥ 2 FDRs suffered PC (OR = 3.88; 95% CI: 2.96-9.73) and among current smokers (OR = 3.16; 95% CI: 2.56-5.78, interaction FHPC*smoking P-value = 0.04). PC cumulative risk by age 75 was 2.2% among FDRs of cases and 0.7% in those of controls [hazard ratio (HR) = 2.42; 95% CI: 2.16-2.71]. PC risk was significantly associated with FH of cancer (OR = 1.30; 95% CI: 1.13-1.54) and diabetes (OR = 1.24; 95% CI: 1.01-1.52), but not with FH of other diseases. The concordant findings using both approaches strengthen the notion that FH of cancer, PC or diabetes confers a higher PC risk. Smoking notably increases PC risk associated with FH of PC. Further evaluation of these associations should be undertaken to guide PC prevention strategies.

    There are many methods of treating laryngeal cancers: definitive irradiation with or without concurrent chemotherapy, endoscopic laser surgery, partial surgery techniques, and total laryngectomy. Few studies have been reported on vocal function and quality of life of patients after the definitive treatment for laryngeal cancer, using single voice related QOL measures. The aim of this study was to examine voice related QOL in patients treated with various modalities using a Voice-Related Quality of Life (V-RQOL) questionnaire as well as Voice Handicap Index-10 (VHI-10) questionnaire. Between August 2006 and May 2007, survey data on voice utilizing the V-RQOL and VHI-10 were obtained from a total of 130 patients who had received definitive treatment for laryngeal cancers with follow-up at the Hokkaido University Hospital, and who were alive with no evidence of malignancy at the time of survey. Mean V-RQOL scores of the patients who received radiation therapy (n=63), chemoradiotherapy (n=29), laser resection (n=14) and total laryngectomy (n=27) as the final treatment for laryngeal cancer were 92.6, 92.9, 85.5, and 68.4, respectively. Mean VHI-10 values were 2.87, 2.34, 5.43, and 11.26. Such measures of quality of life are important endpoints to help judge the overall effectiveness of treatment options for laryngeal cancers.

    The aim of this study was to examine breast density in relation to breast cancer specific survival and to assess if this potential association was modified by mode of detection. An additional aim was to study whether the established association between mode of detection and survival is modified by breast density. The study included 619 cases from a prospective cohort, The Malmö Diet and Cancer Study. Breast density estimated qualitatively, was analyzed in relation to breast cancer death, in non-symptomatic and symptomatic women, using Cox regression calculating hazard ratios (HR) with 95% confidence intervals. Adjustments were made in several steps for; diagnostic age, tumour size, axillary lymph node involvement, grade, hormone receptor status, body mass index (baseline), diagnostic period, use of hormone replacement therapy at diagnosis and mode of detection. Detection mode in relation to survival was analyzed stratified for breast density. Differences in HR following different adjustments were analyzed by Freedmans%. After adjustment for age and other prognostic factors, women with dense, as compared to fatty breasts, had an increased risk of breast cancer death, HR 2.56:1.07-6.11, with a statistically significant trend over density categories, p = 0.04. In the stratified analysis, the effect was less pronounced in non-symptomatic women, HR 2.04:0.49-8.49 as compared to symptomatic, HR 3.40:1.06-10.90. In the unadjusted model, symptomatic women had a higher risk of breast cancer death, regardless of breast density. Analyzed by Freedmans%, age, tumour size, lymph nodes, grade, diagnostic period, ER and PgR explained 55.5% of the observed differences in mortality between non-symptomatic and symptomatic cases. Additional adjustment for breast density caused only a minor change. High breast density at diagnosis may be associated with decreased breast cancer survival. This association appears to be stronger in women with symptomatic cancers but breast density could

    Full Text Available OBJECTIVES:Colorectal cancer is the third leading cause of cancer death in the United States. The American College of Gastroenterology recommends screening for first-degree relatives of patients diagnosed with colorectal cancer before the age of 50. A colonoscopy is one of the most commonly recommended exams due to its specificity and the possibility to resect pre-malignant lesions. Nevertheless, the rate of physician adherence to this recommendation is unknown.METHODS:This transversal study was performed at a major cancer center in Brazil with 62 patients, aged 18 to 50, who completed a questionnaire on information received from their physicians regarding screening their first-degree relatives. We used the answers from patients who provided explicit consent.RESULTS:Two hundred and three patients were eligible to participate and 93 (45.8% agreed to complete the questionnaire. Twenty-three questionnaires (24.73% were returned and 39 were completed by telephone. Of the patients who answered the questionnaire, 39 (62.9% had received a colonoscopy recommendation for their first-degree relatives and 23 (37.1% were not informed of the recommendation. Among the patients who received the recommendations, 20.51% affirmed that all relatives completed the exam and 51.28% stated that no relatives completed the exam.DISCUSSION:The adherence rate of our physicians to the ACG guideline recommendations was 62.9%. Considering that our study was performed at a leading center for cancer treatment in Latin America, we had expected better adherence. The results show that adherence to the colorectal cancer screening recommendations for high-risk patients must be improved.

    The purpose of this study was to evaluate invasive and metastatic potential of urothelial cancer by investigating differential expression of various clock genes/proteins participating in the 24 h circadian rhythms and to compare these gene expressions with transcription of other cancer-associated genes. Twenty seven paired samples of tumour and benign tissue collected from patients who underwent cystectomy were analysed and compared to 15 samples of normal bladder tissue taken from patients who underwent cystoscopy for benign prostate hyperplasia (unrelated donors). Immunohistochemical analyses were made for clock and clock-related proteins. In addition, the gene-expression levels of 22 genes (clock genes, casein kinases, oncogenes, tumour suppressor genes and cytokeratins) were analysed by real-time quantitative PCR (qPCR). Considerable up- or down-regulation and altered cellular distribution of different clock proteins, a reduction of casein kinase1A1 (CSNK1A1) and increase of casein kinase alpha 1 E (CSNK1E) were found. The pattern was significantly correlated with simultaneous up-regulation of stimulatory tumour markers, and a down-regulation of several suppressor genes. The pattern was mainly seen in aneuploid high-grade cancers. Considerable alterations were also found in the neighbouring bladder mucosa. The close correlation between altered expression of various clock genes and common tumour markers in urothelial cancer indicates that disturbed function in the cellular clock work may be an important additional mechanism contributing to cancer progression and malignant behaviour.

    Breast cancer is the cancer most frequently diagnosed in women worldwide. Even though survival rates are continually increasing, breast cancer is often associated with long-term psychological distress, chronic pain, fatigue and impaired quality of life. Yoga comprises advice for an ethical lifestyle, spiritual practice, physical activity, breathing exercises and meditation. It is a complementary therapy that is commonly recommended for breast cancer-related impairments and has been shown to improve physical and mental health in people with different cancer types. To assess effects of yoga on health-related quality of life, mental health and cancer-related symptoms among women with a diagnosis of breast cancer who are receiving active treatment or have completed treatment. We searched the Cochrane Breast Cancer Specialised Register, MEDLINE (via PubMed), Embase, the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 1), Indexing of Indian Medical Journals (IndMED), the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) search portal and Clinicaltrials.gov on 29 January 2016. We also searched reference lists of identified relevant trials or reviews, as well as conference proceedings of the International Congress on Complementary Medicine Research (ICCMR), the European Congress for Integrative Medicine (ECIM) and the American Society of Clinical Oncology (ASCO). We applied no language restrictions. Randomised controlled trials were eligible when they (1) compared yoga interventions versus no therapy or versus any other active therapy in women with a diagnosis of non-metastatic or metastatic breast cancer, and (2) assessed at least one of the primary outcomes on patient-reported instruments, including health-related quality of life, depression, anxiety, fatigue or sleep disturbances. Two review authors independently collected data on methods and results. We expressed outcomes as standardised mean differences (SMDs

    This study aimed to examine the effects of dispositional hope on psychopathology as well as self-perceived positive change in childhood cancer survivors through the potential mediation of cancer-related ruminations. A cross-sectional design was used, and a group of childhood cancer survivors (N = 89; mean age = 23.2 years; age range = 17.2-31.3 years) were studied. Dispositional hope level was measured by the Hope Scale; positive and negative cancer-related ruminations were assessed by the Chinese Cancer-related Rumination Scale; depression symptoms were measured by Beck Depression Inventory; and anxiety symptoms were measured by Beck Anxiety Inventory. Positive adjustment outcome of posttraumatic growth (PTG) was assessed by the Chinese Post-traumatic Growth Inventory. Multiple regressions were used to analyze the relationship between dispositional hope and the outcome variables of PTG, anxiety and depression and the potential mediators of positive and negative cancer-related rumination. Dispositional hope was positively related to PTG, and the correlation was specifically mediated by positive cancer-related rumination. Dispositional hope also correlated with lower levels of depression and anxiety, specifically mediated by negative cancer-related rumination. The present finding supported hope as a significant positive factor for childhood cancer survivors, which was associated with PTG and better psychological adjustment. The findings may inform development of therapeutic intervention programs aimed at increasing childhood cancer patients' hope levels, which may be correlated with more positive cancer-related thoughts and better adjustment. The present study, which examined survivors diagnosed at young age, may enrich existing studies on the effect of onset age and adjustment outcomes. Copyright © 2013 John Wiley & Sons, Ltd.

    The aim of this study is to examine factors contributing to cancer-related fatigue (CRF) in breast cancer patients who have undergone surgery. Sixty women (mean age: 50.0) completed self-rated questionnaires assessing components of CRF, muscular and cognitive functions. Also, physiological and subjective data were gathered. Data were analyzed using partial least squares variance-based structural equation modeling in order to examine factors contributing to CRF after breast surgery. The tested model was robust in terms of its measurement quality (reliability and validity). According to the structural model results, emotional distress (β = 0.59; p accounting for 61% of the explained variance. Also, emotional distress (β = 0.41; p accounted for 41% of the explained variance. However, the relationship between low physical function and CRF was weak and nonsignificant (β = 0.01; p > 0.05). Emotional distress, altered vigilance capacity, and pain are associated with CRF in postsurgical breast cancer. In addition, emotional distress and pain are related to diminished physical function, which, in turn, has no significant impact on CRF. The current model should be examined in subsequent phases of the treatment (chemotherapy and/or radiotherapy) when side effects are more pronounced and may lead to increased intensity of CRF and low physical function.

    The aim of this study was to evaluate cancer-related absenteeism costs in Poland. Data on sickness absences and disability were retrieved from the Department of Statistics of the Social Insurance Institution. The cost of lost productivity owing to premature death was estimated from data retrieved from the Polish National Cancer Registry. Absenteeism costs were estimated on the basis of the measure of gross value added per employee. The costs of lost productivity owing to sick leave, disability, and premature death were estimated to be 1.572 billion EUR, 0.504 billion EUR, and 0.535 billion EUR, respectively, in 2009. The indirect costs of lost productivity owing to cancer-related sick leave, disability, and premature death have a substantial effect on the Polish economy. In 2009, they accounted for more than 0.8% of GDP.

    The aim of this study was to identify demographic and treatment-related factors associated with health-promoting behavior changes after a breast cancer diagnosis. Changes in health behaviors were also evaluated according to weight, exercise, diet and alcohol consumption patterns before breast cancer diagnosis. We examined self-reported behavior changes among 1415 women diagnosed with breast cancer in the NIEHS Sister Study cohort. Women reported changes in exercising, eating healthy foods, maintaining a healthy body weight, drinking alcohol, smoking, getting enough sleep, spending time with family and friends, and participating in breast cancer awareness events. On average, women were 3.7 years from their breast cancer diagnosis. Overall, 20-36% reported positive changes in exercise, eating healthy foods, maintaining a healthy weight, or alcohol consumption. However, 17% exercised less. With each 5-year increase in diagnosis age, women were 11-16% less likely to report positive change in each of these behaviors (OR = 0.84-0.89; p exercise, eating healthy foods, efforts to maintain a healthy weight, alcohol consumption, sleep patterns, or time spent with family or friends. Many women reported no change in cancer survivorship guideline-supported behaviors after diagnosis. Positive changes were more common among younger women or those who underwent chemotherapy.

    Many authors have considered dental implants to be unrelated to increased risk of medication-related osteonecrosis of the jaw (MRONJ). Nevertheless, more recently, more cases of peri-implant MRONJ (PI-MRONJ) have been described, thus becoming a challenging health problem. Also, metastatic cancer deposits are not infrequently found at peri-implant sites and this may represent an additional complication for such treatments. We present the case of a breast cancer patient wi
