    In the last decade, the use of data mining techniques has become widely accepted in medical applications, especially in predicting cancer patients' survival. In this study, we attempted to train an Artificial Neural Network (ANN) to predict the patients' five-year survivability. Breast cancer patients who were diagnosed and received standard treatment in one hospital during 2000 to 2003 in Taiwan were collected for train and test the ANN. There were 604 patients in this dataset excluding died not in breast cancer. Among them 140 patients died within five years after their first radiotherapy treatment. The artificial neural networks were created by STATISTICA(®) software. Five variables (age, surgery and radiotherapy type, tumor size, regional lymph nodes, distant metastasis) were selected as the input features for ANN to predict the five-year survivability of breast cancer patients. We trained 100 artificial neural networks and chose the best one to analyze. The accuracy rate is 85% and area under the receiver operating characteristic (ROC) curve is 0.79. It shows that artificial neural network is a good tool to predict the five-year survivability of breast cancer patients. PMID:24109931

    Full Text Available "nBackground: The aim of this study was to predict the survival rate of Iranian gastric cancer patients using the Cox proportional hazard and artificial neural network models as well as comparing the ability of these approaches in predicting the survival of these patients."nMethods: In this historical cohort study, the data gathered from 436 registered gastric cancer patients who have had surgery between 2002 and 2007 at the Taleghani Hospital (a referral center for gastrointestinal cancers, Tehran, Iran, to predict the survival time using Cox proportional hazard and artificial neural network techniques. "nResults: The estimated one-year, two-year, three-year, four-year and five-year survival rates of the patients were 77.9%, 53.1%, 40.8%, 32.0%, and 17.4%, respectively. The Cox regression analysis revealed that the age at diag-nosis, high-risk behaviors, extent of wall penetration, distant metastasis and tumor stage were significantly associated with the survival rate of the patients. The true prediction of neural network was 83.1%, and for Cox regression model, 75.0%."nConclusion: The present study shows that neural network model is a more powerful statistical tool in predicting the survival rate of the gastric cancer patients compared to Cox proportional hazard regression model. Therefore, this model recommended for the predicting the survival rate of these patients.

    Full Text Available BACKGROUND: Patients with higher levels of fasting serum glucose have higher death rates from pancreatic cancer compared to patients with lower levels of fasting serum glucose. However, the reasons have not been studied. The goal of the current study was to examine the neural alterations in pancreatic cancer patients with hyperglycemia and to identify the relationship between the neural alterations and perineural invasion. METHODOLOGY/PRINCIPAL FINDINGS: The clinical and pathological features of 61 formalin-fixed pancreatic cancer specimens and 10 normal pancreases as controls were analyzed. Furthermore, the expression of Protein Gene Product 9.5 (PGP9.5, Myelin P0 protein (MPP, NGF, TrkA, and p75 were examined by immunohistochemistry. The median number of nerves, the median area of neural tissue, and the median nerve diameter per 10 mm(2 were larger in the hyperglycemia group than those in the euglycemia group (p = 0.007, p = 0.009, and p = 0.004, respectively. The integrated optical density (IOD of MPP staining was lower in the hyperglycemia group than those in the euglycemia group (p = 0.019, while the expression levels of NGF and p75 were higher in the hyperglycemia group than those in the euglycemia group (p = 0.002, and p = 0.026, respectively. The nerve bundle invasion of pancreatic cancer was more frequent in the hyperglycemia group than in the euglycemia group (p = 0.000. CONCLUSIONS/SIGNIFICANCE: Nerve damage and regeneration occur simultaneously in the tumor microenvironment of pancreatic cancer patients with hyperglycemia; the simultaneous occurrence may aggravate the process of perineural invasion. The abnormal expression of NGF and p75 may also be involved in this process and subsequently lead to a lower rate of curative surgery.

    Full Text Available Abstract Background In recent years, artificial neural network is advocated in modeling complex multivariable relationships due to its ability of fault tolerance; while decision tree of data mining technique was recommended because of its richness of classification arithmetic rules and appeal of visibility. The aim of our research was to compare the performance of ANN and decision tree models in predicting hospital charges on gastric cancer patients. Methods Data about hospital charges on 1008 gastric cancer patients and related demographic information were collected from the First Affiliated Hospital of Anhui Medical University from 2005 to 2007 and preprocessed firstly to select pertinent input variables. Then artificial neural network (ANN and decision tree models, using same hospital charge output variable and same input variables, were applied to compare the predictive abilities in terms of mean absolute errors and linear correlation coefficients for the training and test datasets. The transfer function in ANN model was sigmoid with 1 hidden layer and three hidden nodes. Results After preprocess of the data, 12 variables were selected and used as input variables in two types of models. For both the training dataset and the test dataset, mean absolute errors of ANN model were lower than those of decision tree model (1819.197 vs. 2782.423, 1162.279 vs. 3424.608 and linear correlation coefficients of the former model were higher than those of the latter (0.955 vs. 0.866, 0.987 vs. 0.806. The predictive ability and adaptive capacity of ANN model were better than those of decision tree model. Conclusion ANN model performed better in predicting hospital charges of gastric cancer patients of China than did decision tree model.

    Artificial neural network with the back-propagation(BP-ANN) approach was applied to the classification of normal persons and various cancer patients based on the elemental contents in serum samples. This method was verified by the cross-validation method. The effects of the net work parameters were investigated and the related problems were discussed. The samples of 72, 42, and 52 for lung, liver, and stomach cancer patients and normal persons, respectively, were used for the classification study. About 95% of the samples can be classified correctly. There fore, the method can be used as an auxiliary means of the diagnosis of cancer.

    A cut-off of 5 circulating tumor cells (CTCs) per 7.5 ml of blood in metastatic breast cancer (MBC) patients is highly predictive of outcome. We analyzed the relationship between CTCs as a continuous variable and overall survival in immunohistochemically defined primary tumor molecular subtypes using an artificial neural network (ANN) prognostic tool to determine the shape of the relationship between risk of death and CTC count and to predict individual survival. We analyzed a training dataset of 311 of 517 (60%) consecutive MBC patients who had been treated at MD Anderson Cancer Center from September 2004 to 2009 and who had undergone pre-therapy CTC counts (CellSearch(®)). Age; estrogen, progesterone receptor, and HER2 status; visceral metastasis; metastatic disease sites; therapy type and line; and CTCs as a continuous value were evaluated using ANN. A model with parameter estimates obtained from the training data was tested in a validation set of the remaining 206 (40%) patients. The model estimates were accurate, with good discrimination and calibration. Risk of death, as estimated by ANN, linearly increased with increasing CTC count in all molecular tumor subtypes but was higher in ER+ and triple-negative MBC than in HER2+. The probabilities of survival for the four subtypes with 0 CTC were as follows: ER+/HER2- 0.947, ER+/HER2+ 0.959, ER-/HER2+ 0.902, and ER-/HER2- 0.875. For patients with 200 CTCs, they were ER+/HER2- 0.439, ER+/HER2+ 0.621, ER-/HER2+ 0.307, ER-/HER2- 0.130. In this large study, ANN revealed a linear increase of risk of death in MBC patients with increasing CTC counts in all tumor subtypes. CTCs' prognostic effect was less evident in HER2+ MBC patients treated with targeted therapy. This study may support the concept that the number of CTCs, along with the biologic characteristics, needs to be carefully taken into account in future analysis. PMID:21710134

    Cognitive impairment develops as a clinical manifestation of immune-mediated indirect effects of malignancy in lung cancer patients. This study aimed to evaluate the effects of humoral immune response on cognition in lung cancer patients. Fifty-one lung cancer patients were subjected to neurological examination: Mini Mental State Examination (MMSE), Trail Making Test (TMT), and Hamilton scale. The Psychology Experiment Building Language software was used for the evaluation of digit span, simple reaction time (SRT), and choice reaction time (CRT) tests. Serum samples were tested for the presence of onconeuronal antibodies and antineural antibodies. The results demonstrate that autoantibodies were found in 31 % patients. MMSE scores were lower (26.7 ± 2.7) in seropositive patients than in seronegative subjects (28.7 ± 1.2; p = 0.013). Executive functions were also influenced by the presence of autoantibodies. The humoral immune response in lung cancer patients affected both SRT and CRT. We conclude that the humoral immune response in lung cancer patients is associated with cognitive impairment. Cognitive impairment is associated with both specific reactions against onconeuronal or antineural antigens and non-organ specific reactions against nucleosome antigens. PMID:26987335

    International Nuclear Information System (INIS)

    Purpose/Objective(s): The aim of this study is to build the estimator of toxicity using artificial neural network (ANN) for head and neck cancer patients Materials/Methods: An ANN can combine variables into a predictive model during training and considered all possible correlations of variables. We constructed an ANN based on the data from 73 patients with advanced H and N cancer treated with external beam radiotherapy and/or chemotherapy at our institution. For the toxicity estimator we defined input data including age, sex, site, stage, pathology, status of chemo, technique of external beam radiation therapy (EBRT), length of treatment, dose of EBRT, status of post operation, length of follow-up, the status of local recurrences and distant metastasis. These data were digitized based on the significance and fed to the ANN as input nodes. We used 20 hidden nodes (for the 13 input nodes) to take care of the correlations of input nodes. For training ANN, we divided data into three subsets such as training set, validation set and test set. Finally, we built the estimator for the toxicity from ANN output. Results: We used 13 input variables including the status of local recurrences and distant metastasis and 20 hidden nodes for correlations. 59 patients for training set, 7 patients for validation set and 7 patients for test set and fed the inputs to Matlab neural network fitting tool. We trained the data within 15% of errors of outcome. In the end we have the toxicity estimation with 74% of accuracy. Conclusion: We proved in principle that ANN can be a very useful tool for predicting the RT outcomes for high risk H and N patients. Currently we are improving the results using cross validation

    Full Text Available Functional neuroimaging is an innovative but at this stage underutilized method to assess the efficacy of psychotherapy for depression. Functional magnetic resonance imaging (fMRI was used in this case study to examine changes in brain activity in a depressed breast cancer patient receiving an 8-session Behavioral Activation Treatment for Depression (BATD, based on the work of Hopko and Lejuez (2007. A music listening paradigm was used during fMRI brain scans to assess reward responsiveness at pre- and posttreatment. Following treatment, the patient exhibited attenuated depression and changes in blood oxygenation level dependence (BOLD response in regions of the prefrontal cortex and the subgenual cingulate cortex. These preliminary findings outline a novel means to assess psychotherapy efficacy and suggest that BATD elicits functional brain changes in areas implicated in the pathophysiology of depression. Further research is necessary to explore neurobiological mechanisms of change in BATD, particularly the potential mediating effects of reward responsiveness and associated brain functioning.

    Full Text Available The aim of this study was to compare multilayer perceptron neural networks (NNs with standard logistic regression (LR to identify key covariates impacting on mortality from cancer causes, disease-free survival (DFS, and disease recurrence using Area Under Receiver-Operating Characteristics (AUROC in breast cancer patients. From 1996 to 2004, 2,535 patients diagnosed with primary breast cancer entered into the study at a single French centre, where they received standard treatment. For specific mortality as well as DFS analysis, the ROC curves were greater with the NN models compared to LR model with better sensitivity and specificity. Four predictive factors were retained by both approaches for mortality: clinical size stage, Scarff Bloom Richardson grade, number of invaded nodes, and progesterone receptor. The results enhanced the relevance of the use of NN models in predictive analysis in oncology, which appeared to be more accurate in prediction in this French breast cancer cohort.

    Accurate and reliable decision making in breast cancer prognosis can help in the planning of suitable surgery and therapy and, generally, optimise patient management through the different stages of the disease. In recent years, several prognostic factors have been used as indicators of disease progression in breast cancer. In this paper we investigate a fuzzy method, namely fuzzy k-nearest neighbour technique for breast cancer prognosis, and for determining the significance of prognostic markers and subsets of the markers, which include histology type, tumour grade, DNA ploidy, S-phase fraction, G0G1/G2M ratio, and minimum (start) and maximum (end) nuclear pleomorphism indices. We also compare the method with (a) logistic regression as a statistical method, and (b) multilayer feed forward backpropagation neural networks as an artificial neural network tool, the latter two techniques having been widely used for cancer prognosis. Nodal involvement and survival analyses in breast cancer are carried out for 100 women who were clinically diagnosed with breast disease in the form of carcinoma and benign conditions, and seven prognostic markers collected for each patient. For nodal involvement analysis, node positive and negative patients are predicted whereas survival analysis is carried out for two categories: whether a patient is alive or dead within 5 years of diagnosis. The results obtained show that the fuzzy method yields the highest predictive accuracy of 88% for both nodal involvement and survival analyses obtained from the subsets of [tumour grade, S-phase fraction, minimum (start) nuclear pleomorphism index] and [tumour histology type, DNA ploidy, S-phase fraction, G0G1/G2M ratio], respectively. We believe that this technique has produced more reliable prognostic factor models than those obtained using either the statistical or artificial neural networks-based methods. PMID:12017328

    Nearly 20% patients with stage II A colon cancer will develop recurrent disease post-operatively. The present study aims to develop a scoring system based on Artificial Neural Network (ANN) model for predicting 10-year survival outcome. The clinical and molecular data of 117 stage II A colon cancer patients from Sun Yat-sen University Cancer Center were used for training set and test set; poor pathological grading (score 49), reduced expression of TGFBR2 (score 33), over-expression of TGF-β (score 45), MAPK (score 32), pin1 (score 100), β-catenin in tumor tissue (score 50) and reduced expression of TGF-β in normal mucosa (score 22) were selected as the prognostic risk predictors. According to the developed scoring system, the patients were divided into 3 subgroups, which were supposed with higher, moderate and lower risk levels. As a result, for the 3 subgroups, the 10-year overall survival (OS) rates were 16.7%, 62.9% and 100% (P < 0.001); and the 10-year disease free survival (DFS) rates were 16.7%, 61.8% and 98.8% (P < 0.001) respectively. It showed that this scoring system for stage II A colon cancer could help to predict long-term survival and screen out high-risk individuals for more vigorous treatment. PMID:27008710

  15. Neural network analysis of breast cancer from MRI findings

    International Nuclear Information System (INIS)

    To evaluate how much the experience of radiologists affects the performance of an artificial neural network (ANN) trained by two highly experienced radiologists. Before biopsy two experienced radiologists reviewed the MR images of 100 adult patients with suspicious breast lesions and evaluated their findings based on six features. This database was then used to train a three-layered feed-forward neural network. The network's generalizing ability was then tested to predict the outcome of biopsy in 56 new patients' records which were extracted by 10 participating radiologists. The MRI findings of each reader were presented to the ANN to evaluate the effect of various levels of experience on the output of the ANN. The performance of the ANN was then compared with that of attendant physicians in terms of sensitivity, specificity, and accuracy as well as ROC analysis. The best ANN outcome offered a correct diagnosis in 40 of 41 of the patients with malignant breast cancer and 10 of 15 with benign entity presented in the testing set. The output of the trained ANN outperformed the attendant radiologists with low levels of experience and showed comparable performance with radiologists with higher levels of experience. The ANN is able to work as a backup system to assist radiologists in the diagnosis of breast cancer. (author)

With development of psycho-oncology it has been demonstrated to establish an important link between the cancer patient`s treatment as well as psycho-social support for the patient and psychiatric treatment and care for the if it is needed. With this connection between them it has been proposed to use of bio-psycho-social-model in cancer patient to improve their care. To achieve this goal, it is expected from medical personnel to realize patients psychosocial need und if he/she has a psychiatric disorders or syndromes. For the medical personnel that work in oncology services, it is inevitable to organize in order to raise the awareness of depression in the cancer patients. In the present study, it is focused on raising the awareness of depression in cancer patient for the medical personnel.

    The tumor microenvironment is known to play a pivotal role in driving cancer progression and governing response to therapy. This is of significance in pancreatic cancer where the unique pancreatic tumor microenvironment, characterized by its pronounced desmoplasia and fibrosis, drives early stages of tumor progression and dissemination, and contributes to its associated low survival rates. Several molecular factors that regulate interactions between pancreatic tumors and their surrounding stroma are beginning to be identified. Yet broader physiological factors that influence these interactions remain unclear. Here, we discuss a series of preclinical and mechanistic studies that highlight the important role chronic stress plays as a physiological regulator of neural-tumor interactions in driving the progression of pancreatic cancer. These studies propose several approaches to target stress signaling via the β-adrenergic signaling pathway in order to slow pancreatic tumor growth and metastasis. They also provide evidence to support the use of β-blockers as a novel therapeutic intervention to complement current clinical strategies to improve cancer outcome in patients with pancreatic cancer.

  2. Insomnia in cancer patients.

    2004-01-01

    Insomnia affects up to 50% of patients with cancer, but has received little attention from the oncology community compared with other symptoms such as pain and fatigue. Insomnia and subsequent sleep disturbances can lead to fatigue, mood disturbances, and contribute to immunosuppression, which can have a profound impact on quality of life and perhaps affect the course of disease. Insomnia in cancer patients must be distinguished from cancer-related fatigue. Although they are 2 distinct conditions, insomnia and fatigue are interrelated. Insomnia often leads to daytime fatigue that interferes with normal functioning. Conversely, daytime fatigue can lead to behaviors such as napping, which result in insomnia. The primary goal of insomnia treatment should first be to relieve any underlying disorder (eg, cancer pain, depression, anxiety) that may be causing the sleep disturbance. Because insomnia in this patient population may be due to a variety of causes, treatment must be multimodal and include both pharmacologic and nonpharmacologic therapies. A plan that combines attention to sleep hygiene and cognitive-behavioral therapy with prescription of hypnotic medications can help relieve the symptoms of insomnia in cancer patients and improve their quality of life.

    Neural cancers display cellular hierarchies with self-renewing tumorigenic cancer stem cells (CSCs) at the apex. Instructive cues to maintain CSCs are generated by both intrinsic networks and the niche microenvironment. The CSC-microenvironment relationship is complex as CSCs can modify their environment and extrinsic forces induce plasticity in the cellular hierarchy.

    We study the impact of the decrease in the neural population on the neuronal firing rate. We propose a cellular automaton model from cancerous growth in a brain tissue and the death of neurons due absence of cells that help support to neurons. We use this model to study how the firing rate changes when the neuronal networks is under different external stimuli and the cancerous cells have different proliferation rate. Our work shows that the cancer proliferation decreases the neuronal firing rate.

    This paper reports on the performance of a recently developed neural network environment incorporating likelihood-based optimization and complexity reduction techniques in the analysis of breast cancer follow-up data with the goal of building up a clinical decision support system. The inputs to the neural network include classical factors such as grading, age, tumor size, estrogen and progesterone receptor measurements, as well as tumor biological markers such as PAI-1 and uPA. The network learns the structural relationship between these factors and the follow-up data. Examples of neural models for relapse-free survival are presented, which are based on data from 784 breast cancer patients who received their primary therapy at the Department of Obstetrics and Gynecology, Technische Universität München, Germany. The performance of the neural analysis as quantified by various indicators (likelihood, Kaplan-Meier curves, log-rank tests) was very high. For example, dividing the patients into two equally sized groups based on the neural score (i.e., cutoff = median score) leads to an estimated difference in relapse-free survival of 40% or better (80% vs. 40%) after 10 years in Kaplan-Meier analysis. Evidence for factor interactions as well as for time-varying impacts is presented. The neural network weights included in the models are significant at the 5% level. The use of neural network analysis and scoring in combination with strong tumor biological factors such as uPA and PAI-1 appears to result in a very effective risk group discrimination. Considerable additional comparison of data from different patient series will be required to establish the generalization capability more firmly. Nonetheless, the improvement of risk group discrimination represents an important step toward the use of neural networks for decision support in a clinical framework and in making the most of biological markers.

    Full Text Available Venous thromboembolism (VTE is a major complication of cancer and represents an important cause of morbidity and mortality. The incidence of VTE is 0.6-7.8% in patients with cancer more than double the incidence of VTE in patients without cancer. The risk of VTE which includes deep venous thrombosis (DVT and pulmonary embolism (PE is increased two to seven fold in patients with cancer. VTE risk is especially high among certain groups such as hospitalized patients with cancer and those receiving active antineoplastic therapy. Also cancer patients, who undergoing major surgery, are increased risk of VTE. Trauma, long-haul travel, increased age, obesity, previous VTE and genetic component are also predisposing factors for VTE. Patients with cancer who develop VTE should be managed multidisciplinary treatment guidelines. The primary goal of thromboprophylaxis in patients with cancer is to prevent VTE. The large majority of cancer patients should be treated with therapeutic doses of unfractioned heparin (UFH or low molecular weight heparin (LMWH. Prophylaxis should include cancer patients who underwent major surgery for cancer and patients with a history of VTE.

    Artificial neural networks (ANNs) can be used to develop a technique to classify lymph node negative breast cancer that is prone to distant metastases based on gene expression signatures. The neural network used is a multilayered feed forward network that employs back propagation algorithm. Once trained with DNA microarraybased gene expression profiles of genes that were predictive of distant metastasis recurrence of lymph node negative breast cancer, the ANNs became capable of correctly classifying all samples and recognizing the genes most appropriate to the classification. To test the ability of the trained ANN models in recognizing lymph node negative breast cancer, we analyzed additional idle samples that were not used beforehand for the training procedure and obtained the correctly classified result in the validation set. For more substantial result, bootstrapping of training and testing dataset was performed as external validation. This study illustrates the potential application of ANN for breast tumor diagnosis and the identification of candidate targets in patients for therapy.

    It is often difficult to identify cancer tissue during brain cancer (glioma) surgery. Gliomas invade into areas of normal brain, and this cancer invasion is frequently not detected using standard preoperative magnetic resonance imaging (MRI). This results in enduring invasive cancer following surgery and leads to recurrence. A hand-held Raman spectroscopy is able to rapidly detect cancer invasion in patients with grade 2-4 gliomas. However, ambient light sources can produce spectral artifacts which inhibit the ability to distinguish between cancer and normal tissue using the spectral information available. To address this issue, we have demonstrated that artificial neural networks (ANN) can accurately classify invasive cancer versus normal brain tissue, even when including measurements with significant spectral artifacts from external light sources. The non-parametric and adaptive model used by ANN makes it suitable for detecting complex non-linear spectral characteristics associated with different tissues and the confounding presence of light artifacts. The use of ANN for brain cancer detection with Raman spectroscopy, in the presence of light artifacts, improves the robustness and clinical translation potential for intraoperative use. Integration with the neurosurgical workflow is facilitated by accounting for the effect of light artifacts which may occur, due to operating room lights, neuronavigation systems, windows, or other light sources. The ability to rapidly detect invasive brain cancer under these conditions may reduce residual cancer remaining after surgery, and thereby improve patient survival.

    2016-05-01

    Despite recent progress in cancer research, the exact nature of malignant transformation and its progression is still not fully understood. Particularly metastasis, which accounts for most cancer death, is a very complex process, and new treatment strategies require a more comprehensive understanding of underlying regulatory mechanisms. Recently, the sympathetic nervous system (SNS) has been implicated in cancer progression and beta-blockers have been identified as a novel strategy to limit metastasis. This review discusses evidence that SNS signaling regulates metastasis by modulating the physical characteristics of tumor cells, tumor-associated immune cells and the extracellular matrix (ECM). Altered mechanotype is an emerging hallmark of cancer cells that is linked to invasive phenotype and treatment resistance. Mechanotype also influences crosstalk between tumor cells and their environment, and may thus have a critical role in cancer progression. First, we discuss how neural signaling regulates metastasis and how SNS signaling regulates both biochemical and mechanical properties of tumor cells, immune cells and the ECM. We then review our current knowledge of the mechanobiology of cancer with a focus on metastasis. Next, we discuss links between SNS activity and tumor-associated inflammation, the mechanical properties of immune cells, and how the physical properties of the ECM regulate cancer and metastasis. Finally, we discuss the potential for clinical translation of our knowledge of cancer mechanobiology to improve diagnosis and treatment. PMID:27350878

    Full Text Available Cancer is the most important cause of death for both men and women. The early detection of cancer can be helpful in curing the disease completely. So the requirement of techniques to detect the occurrence of cancer nodule in early stage is increasing. A disease that is commonly misdiagnosed is lung cancer. Artificial Neural Networks (ANNs play a vital role in the medical field in solving various health problems like acute diseases and even other mild diseases. Earlier diagnosis of Lung Cancer saves enormous lives, failing which may lead to other severe problems causing sudden fatal end. Its cure rate and prognosis depends mainly on the early detection and diagnosis of the disease. This paper provides a Feed Forward Artificial Neural Network Model for early detection of lung cancer. The model consists of an input layer, a hidden layer and an output layer. The network is trained with one hidden layer and one output layer by giving twelve inputs. One of the most common forms of medical malpractices globally is an error in diagnosis. The paper provides a formula for Error Detection and on the basis of error weights are adjusted and system is improved. Aim of the paper is to propose a model for early detection and correct diagnosis of the disease which will help the doctor in saving the life of the patient.

    MicroRNAs (miRNAs) have been shown to be promising biomarkers in predicting cancer prognosis. However, inappropriate or poorly optimized processing and modeling of miRNA expression data can negatively affect prediction performance. Here, we propose a holistic solution for miRNA biomarker selection and prediction model building. This work introduces the use of a neural network cascade, a cascaded constitution of small artificial neural network units, for evaluating miRNA expression and patient outcome. A miRNA microarray dataset of nasopharyngeal carcinoma was retrieved from Gene Expression Omnibus to illustrate the methodology. Results indicated a nonlinear relationship between miRNA expression and patient death risk, implying that direct comparison of expression values is inappropriate. However, this method performs transformation of miRNA expression values into a miRNA score, which linearly measures death risk. Spearman correlation was calculated between miRNA scores and survival status for each miRNA. Finally, a nine-miRNA signature was optimized to predict death risk after nasopharyngeal carcinoma by establishing a neural network cascade consisting of 13 artificial neural network units. Area under the ROC was 0.951 for the internal validation set and had a prediction accuracy of 83% for the external validation set. In particular, the established neural network cascade was found to have strong immunity against noise interference that disturbs miRNA expression values. This study provides an efficient and easy-to-use method that aims to maximize clinical application of miRNAs in prognostic risk assessment of patients with cancer. PMID:25310846

    Full Text Available Aims and Objectives: Pulmonary embolism (PE is rare in the Indian population and is under-reported in patients with malignancy. We studied the clinical profile and outcome of patients with PE and cancer in the Indian population. Materials and Methods: Data of cancer patients with PE, admitted in a tertiary cancer centre, was analyzed. The prevalence of PE was calculated as the number of patients with PE per 10,000 hospital admissions. The demographic data, details of cancer, co-morbidities, details of PE, and treatment given for PE and their outcomes were recorded and analyzed. Results: There were 56,425 hospital admissions in the study period. The prevalence of PE was 6.4 per 10,000 hospital admissions .Thirty-six cancer patients were diagnosed to have PE. In females, gynecological malignancies (36.84% and in males gastrointestinal, head and neck cancers, and hematological malignancies were the most common sites (17.7% each. PE was associated with DVT in 41.7%. Dyspnea was the most common presenting symptom. Five patients (13.88% were asymptomatic and were incidentally detected to have PE . The most common echocardiographic finding was right ventricular dysfunction (55.55%. Mortality among the treated patients was 22% (7 / 31 and in untreated patients it was 80% (4 / 5. The factors that had an impact on a three-month survival were, the presence of massive PE (P = 0.019 and the presence of RV dysfunction at presentation (P = 0.005. Conclusion: The prevalence of PE and mortality due to PE is high in cancer patients. Risk stratification for venous thromboembolism (VTE should be done in all cancer patients and thromboprophylaxis should be optimally used.

  12. Bayesian neural networks for bivariate binary data: an application to prostate cancer study.

    Chakraborty, Sounak; Ghosh, Malay; Maiti, Tapabrata; Tewari, Ashutosh

    2005-12-15

    Prostate cancer is one of the most common cancers in American men. The cancer could either be locally confined, or it could spread outside the organ. When locally confined, there are several options for treating and curing this disease. Otherwise, surgery is the only option, and in extreme cases of outside spread, it could very easily recur within a short time even after surgery and subsequent radiation therapy. Hence, it is important to know, based on pre-surgery biopsy results how likely the cancer is organ-confined or not. The paper considers a hierarchical Bayesian neural network approach for posterior prediction probabilities of certain features indicative of non-organ confined prostate cancer. In particular, we find such probabilities for margin positivity (MP) and seminal vesicle (SV) positivity jointly. The available training set consists of bivariate binary outcomes indicating the presence or absence of the two. In addition, we have certain covariates such as prostate specific antigen (PSA), gleason score and the indicator for the cancer to be unilateral or bilateral (i.e. spread on one or both sides) in one data set and gene expression microarrays in another data set. We take a hierarchical Bayesian neural network approach to find the posterior prediction probabilities for a test and validation set, and compare these with the actual outcomes for the first data set. In case of the microarray data we use leave one out cross-validation to access the accuracy of our method. We also demonstrate the superiority of our method to the other competing methods through a simulation study. The Bayesian procedure is implemented by an application of the Markov chain Monte Carlo numerical integration technique. For the problem at hand, our Bayesian bivariate neural network procedure is shown to be superior to the classical neural network, Radford Neal's Bayesian neural network as well as bivariate logistic models to predict jointly the MP and SV in a patient in both the

    2015-03-01

    Testicular cancer(TC)is the most common and curable cancer affecting men of reproductive age. Successful treatment approaches have resulted in longer life expectancy in TC survivors. The most frequently used treatment for TC is a combination of inguinal orchiectomy, and either radiotherapy or cisplatin-based chemotherapy. In many TC patients, sperm quality is already abnormal and there may even be a lack of viable spermatozoa at the time of diagnosis. Therefore, the effect of cancer treatment on fertility is a potentially significant issue. Fertility preservation in these men has become essential and needs to be discussed prior to the start of cancer treatment. The only currently established fertility preservation method is the cryopreservation of sperm before therapy. For most patients seeking cryopreservation, the semen sample is collected via masturbation. If the patient is unable to ejaculate for any reason, other techniques such as vibratory stimulation and electroejaculation can be performed. In azoospermic or severely oligozoospermic patients, testicular sperm extraction at the time of the inguinal orchiectomy is a useful technique for obtaining spermatozoa before cytotoxic therapy. We herein present an overview of the current topics on fertility in TC patients, including the effects of surgery, chemotherapy, and radiation therapy. We also describe the strategy for fertility preservation in these patients. PMID:25812494

  15. Hypertension in Patients with Cancer

    International Nuclear Information System (INIS)

    There is a known association between chemotherapy and radiotherapy for treatment of cancer patients and development or worsening of hypertension. The aim of this article is to review this association. A literature search was conducted for articles reporting this association on the databases PubMed, SciELO and LILACS between 1993 and 2013. There was a high coprevalence of hypertension and cancer, since both diseases share the same risk factors, such as sedentary lifestyle, obesity, smoking, unhealthy diet and alcohol abuse. The use of chemotherapy and adjuvant drugs effective in the treatment of cancer increased the survival rate of these patients and, consequently, increased the incidence of hypertension. We described the association between the use of angiogenesis inhibitors (bevacizumab, sorafenib and sunitinib), corticosteroids, erythropoietin and non-steroidal anti-inflammatory drugs with the development of hypertension. We also described the relationship between hypertension and carotid baroreceptor injury secondary to cervical radiotherapy.

    There is a known association between chemotherapy and radiotherapy for treatment of cancer patients and development or worsening of hypertension. The aim of this article is to review this association. A literature search was conducted for articles reporting this association on the databases PubMed, SciELO and LILACS between 1993 and 2013. There was a high coprevalence of hypertension and cancer, since both diseases share the same risk factors, such as sedentary lifestyle, obesity, smoking, unhealthy diet and alcohol abuse. The use of chemotherapy and adjuvant drugs effective in the treatment of cancer increased the survival rate of these patients and, consequently, increased the incidence of hypertension. We described the association between the use of angiogenesis inhibitors (bevacizumab, sorafenib and sunitinib), corticosteroids, erythropoietin and non-steroidal anti-inflammatory drugs with the development of hypertension. We also described the relationship between hypertension and carotid baroreceptor injury secondary to cervical radiotherapy. Morbidity and mortality increased in patients with cancer and hypertension without proper antihypertensive treatment. We concluded that there is need for early diagnosis, effective monitoring and treatment strategies for hypertension in cancer patients in order to reduce cardiovascular morbidity and mortality.

    Cancer patients are regularly affected by malnutrition which often leads to a worsened quality of life and activity in daily living, more side effects and complications during anticancer treatment and shorter survival times. The early diagnosis and treatment of malnutrition are therefore relevant components of oncological treatment. The assessment of the nutritional status and determination of the body-mass-index should be done in every patient with cancer. The clinical examination delivers important findings and indications for malnutrition. Bioimpedance analysis can deliver additional objective information. The treatment of malnutrion should start early and follows a step-wise escalation reaching from nutritional counseling to enteral nutritional support to parenteral nutrition. PMID:26886037

    Prevalence of hypogonadism in men with cancer has been reported between 40% and 90%, which is significantly higher than in the general population. Hypogonadism is likely to affect the quality of life in these patients by contributing to non-specific symptoms, including decreased energy, anorexia, sarcopenia, weight loss, depression, insomnia, fatigue, weakness, and sexual dysfunction. Pathogenesis of hypogonadism in cancer patients is thought to be multi-factorial. Inflammation may play an important role, but leptin, opioids, ghrelin, and high-dose chemotherapy through different mechanisms have all been implicated as the cause. Hypogonadism is also associated with poor survival in cancer patients. Data looking into the treatment of hypogonadal male cancer patients with testosterone are limited. However, improvements in body weight, muscle strength, lean body mass, and quality of life have been shown in hypogonadal men with other chronic diseases on testosterone replacement therapy. Prospective and interventional trials are needed to test the efficacy and safety of testosterone treatment in improving quality of life of these patients. PMID:22528986

    Full Text Available Background/Objective: Mammographic differentiation of benign lesions from malignancies is a difficult task. We developed an artificial neural network (ANN as a diagnostic aid in mammography using radiographic features as input. Materials & Methods: A three-layered ANN was used to differentiate malignant from benign findings in a group of patients with proven breast lesions on the basis of morphological data extracted from conventional mammograms. Our database included 122 patient records on 14qualitative variables. The database was randomly divided into training and validation samples including 82 and 40 patient records, respectively, to construct the ANN and validate its performance. Sensitivity, specificity, accuracy and receiver operating characteristic curve (ROC analysis for this method and the radiologist were compared. Results: Our results showed that the neural network model was able to correctly classify 30 out of 40 cases presented in the validation sample. Comparing the output with that of the radiologist, showed a reasonable diagnostic accuracy (75%, a moderate specificity (64% and a relatively high sensitivity (89%. Conclusion: A diagnostic aid was developed that accurately differentiates malignant from benign pattern using radiological features extracted from mammograms.

    Fourier-transform infrared spectroscopy has shown alterations of spectral characteristics of cells and tissues as a result of carcinogenesis. The research reported here focuses on the diagnosis of cancer in formalin-fixed biopsied tissue for which immunochemistry is not possible and when PAP-smear results are to be confirmed. The data from two groups of patients (a control group and a group of patients diagnosed with cervical cancer) were analyzed. It was found that the glucose/phosphate ratio decreases (by 23-49%) and the RNA/DNA ratio increases (by 38-150%) in carcinogenic compared with normal tissue. Fourier-transform microspectroscopy was used to examine these tissues. This type of study in larger populations may help to set standards or classes with which to use treated biopsied tissue to predict the possibility of cancer. Probabilistic neural networks and statistical tests as parts of these biopsies predict the possibility of cancer with a high degree of accuracy (>95%).

  5. Limb edemas in cancer patients

    International Nuclear Information System (INIS)

    Diagnostic radiology in cancer patients suffering from limb edemas serves two main purposes: to detect or to rule out lymph node metastases, recurrent cancer, or secondary malignancies, and to differentiate venous edema from lymphedema. The authors suggest an algorithmic pathway where the non-invasive imaging modalities, real-time ultrasonography and computed tomography are recommended as the initial diagnostic step. Both techniques are equally well suited to detect enlarged lymph nodes with high accuracy. In addition, computed tomography allows to a certain degree to separate venous from lymphedema. Phlebography is rarely needed in these patients. Lymphography should only be considered in patients undergoing microsurgical reconstructive operations of the lymphatics (e.g. lymphovenous anastomoses) because this invasive study carries the risk of deteriorating the edematous limb.

  8. A neural network approach to breast cancer diagnosis as a constraint satisfaction problem

    International Nuclear Information System (INIS)

    A constraint satisfaction neural network (CSNN) approach is proposed for breast cancer diagnosis using mammographic and patient history findings. Initially, the diagnostic decision to biopsy was formulated as a constraint satisfaction problem. Then, an associative memory type neural network was applied to solve the problem. The proposed network has a flexible, nonhierarchical architecture that allows it to operate not only as a predictive tool but also as an analysis tool for knowledge discovery of association rules. The CSNN was developed and evaluated using a database of 500 nonpalpable breast lesions with definitive histopathological diagnosis. The CSNN diagnostic performance was evaluated using receiver operating characteristic analysis (ROC). The results of the study showed that the CSNN ROC area index was 0.84±0.02. The CSNN predictive performance is competitive with that achieved by experienced radiologists and backpropagation artificial neural networks (BP-ANNs) presented before. Furthermore, the study illustrates how CSNN can be used as a knowledge discovery tool overcoming some of the well-known limitations of BP-ANNs

    Full Text Available Prostate cancer is one of the most common types of cancer found in men. Presenting a classifier in order classifies between Prostate Cancer (PCa and benign hyperplasia of prostate (BPH, has been great challenge among computer experts and medical specialists. There are a number of techniques proposed to perform such classification. Neural networks are one of the artificial intelligent techniques that have successful examples when applying to such problems. The increasing demand of Artificial Neural Network applications for predicting the disease shows better performance in the field of medical decision-making. This paper presents a comparison of neural network techniques for classification prostate neoplasia diseases. The classification performance obtained by four different types of neural networks for comparison are Back Propagation Neural Network (BPNN, General Regression Neural Network(GRNN, Probabilistic Neural Network (PNN and Radial Basis Function Neural Network (RBFNN. Result of these evaluation show that the overall performance of RBFNN can be apply successfully for detecting and diagnosing the cancer from benign hyperplasia of prostate.

    Ionizing radiation used in treating the head and neck area produces oral side effects such as mucositis, salivary changes, trismus and radiation caries. Sequelae of cancer chemotherapy often include oral stomatitis, myelosuppression and immunosuppression. Infections of dental origin in compromised patients are potentially lethal. Specific programs to eliminate dental pathology before radiation and chemotherapy, and to maintain oral hygiene during and after therapy, will minimize these complications

    One way that solid tumors disseminate is through neural invasion. This route is well-known in cancers of the head and neck, prostate, and pancreas. These neurotropic cancer cells have a unique ability to migrate unidirectionally along nerves towards the central nervous system (CNS). The dorsal root ganglia (DRG)/cancer cell model is a three dimensional (3D) in vitro model frequently used for studying the interaction between neural stroma and cancer cells. In this model, mouse or human cancer cell lines are grown in ECM adjacent to preparations of freshly dissociated cultured DRG. In this article, the DRG isolation protocol from mice, and implantation in petri dishes for co-culturing with pancreatic cancer cells are demonstrated. Five days after implantation, the cancer cells made contact with the DRG neurites. Later, these cells formed bridgeheads to facilitate more extensive polarized, neurotropic migration of cancer cells.

    Full Text Available Prostate, pancreatic, and head and neck carcinomas have a high propensity to invade nerves. Surgical resection is a treatment modality for these patients, but it may incur significant deficits. The development of an imaging method able to detect neural invasion (NI by cancer cells may guide surgical resection and facilitate preservation of normal nerves. We describe an imaging method for the detection of NI using a herpes simplex virus, NV1066, carrying tyrosine kinase and enhanced green fluorescent protein (eGFP. Infection of pancreatic (MiaPaCa2, prostate (PC3 and DU145, and adenoid cystic carcinoma (ACC3 cell lines with NV1066 induced a high expression of eGFP in vitro. An in vivo murine model of NI was established by implanting tumors into the sciatic nerves of nude mice. Nerves were then injected with NV1066, and infection was confirmed by polymerase chain reaction. Positron emission tomography with [18F]-2′-fluoro-2′-deoxyarabinofuranosyl-5-ethyluracil performed showed significantly higher uptake in NI than in control animals. Intraoperative fluorescent stereoscopic imaging revealed eGFP signal in NI treated with NV1066. These findings show that NV1066 may be an imaging method to enhance the detection of nerves infiltrated by cancer cells. This method may improve the diagnosis and treatment of patients with neurotrophic cancers by reducing injury to normal nerves and facilitating identification of infiltrated nerves requiring resection.

    We propose a fast and accurate patient-specific electrocardiogram (ECG) classification and monitoring system using an adaptive implementation of 1D Convolutional Neural Networks (CNNs) that can fuse feature extraction and classification into a unified learner. In this way, a dedicated CNN will be trained for each patient by using relatively small common and patient-specific training data and thus it can also be used to classify long ECG records such as Holter registers in a fast and accurate manner. Alternatively, such a solution can conveniently be used for real-time ECG monitoring and early alert system on a light-weight wearable device. The experimental results demonstrate that the proposed system achieves a superior classification performance for the detection of ventricular ectopic beats (VEB) and supraventricular ectopic beats (SVEB).

    Assessment of the real state of wound healing of closed surgical wounds is uncertain both clinically and from conventional laboratory tests. Therefore, a novel approach based on early analysis of exactly timed wound cells, computerized further with an artificial neural network, was developed. At the end of routine surgery performed on 481 children under 18 years of age, a specific wound drain Cellstick™ was inserted subcutaneously between the wound edges to harvest wound cells. The Cellsticks™ were removed from 1 to 50 hours, mainly at hour 3 or 24 postsurgery. Immediately, the cellular contents were washed out using a pump constructed for the purpose. After cytocentrifugation, the cells were stained and counted differentially. Based on their relative proportions at selected time intervals, an artificial self-organizing neural map was developed. This was further transformed to a unidirectional linear graph where each node represents one set of relative cell quantities. As early as 3 hours, but more precisely 24 hours after surgery, the location of the nodes on this graph showed individually the patients' initial speed of wound inflammatory cell response. Similarly, timed Cellstick™ specimens from new surgical patients could be analyzed, computerized, and compared with these node values to assess their initial speed in wound inflammatory cell response. Location of the node on the graph does not express the time lapse after surgery but the speed of wound inflammatory cell response in relation to that of other patients. PMID:21362082

    This study is designed to assess the application of neural networks in comparison to the Kaplan-Meier and Cox proportional hazards model in the survival analysis. Three hundred thirty gastric cancer patients admitted to and surgically treated were assessed and their post-surgical survival was determined. The observed baseline survival was determined with the three methods of Kaplan-Meier product limit estimator, Cox and the neural network and results were compared. Then the binary independent variables were entered into the model. Data were randomly divided into two groups of 165 each to test the models and assess the reproducibility. The Chi-square test and the multiple logistic model were used to ensure the groups were similar and the data was divided randomly. To compare subgroups, we used the log-rank test. In the next step, the probability of survival in different periods was computed based on the training group data using the Cox proportional hazards and a neural network and estimating Cox coefficient values and neural network weights (with 3 nodes in hidden layer). Results were used for predictions in the test group data and these predictions were compared using the Kaplan-Meier product limit estimator as the gold standard. Friedman and Kruskal-Wallis tests were used for comparisons as well. All statistical analyses were performed using SPSS version 11.5, Matlab version 7.2, Statistica version 6.0 and S_PLUS 2000. The significance level was considered 5% (alpha = 0.05). The three methods used showed no significance difference in base survival probabilities. Overall, there was no significant difference among the survival probabilities or the trend of changes in survival probabilities calculated with the three methods, but the 4 year (48th month) and 4.5 year (54th month) survival rates were significantly different with Cox compared to standard and estimated probabilities in the neural network (p survival probabilities, but results with the neural network were

    Full Text Available Effective identification of lung cancer at an initial stage is an important and crucial aspect of image processing. Several data mining methods have been used to detect lung cancer at early stage. In this paper, an approach has been presented which will diagnose lung cancer at an initial stage using CT scan images which are in Dicom (DCM format. One of the key challenges is to remove white Gaussian noise from the CT scan image, which is done using non local mean filter and to segment the lung Otsu’s thresholding is used. The textural and structural features are extracted from the processed image to form feature vector. In this paper, three classifiers namely SVM, ANN, and k-NN are applied for the detection of lung cancer to find the severity of disease (stage I or stage II and comparison is made with ANN, and k-NN classifier with respect to different quality attributes such as accuracy, sensitivity(recall, precision and specificity. It has been found from results that SVM achieves higher accuracy of 95.12% while ANN achieves 92.68% accuracy on the given data set and k-NN shows least accuracy of 85.37%. SVM algorithm which achieves 95.12% accuracy helps patients to take remedial action on time and reduces mortality rate from this deadly disease.

    Breast cancer is the third most common illness in the world and the most frequent malignant disease with women. Cytotoxic therapy is connected to significant psychiatric adverse effects, and the appearance of depressive symptoms is the most common. The main goal is determining the degree of depression with breast cancer patients in the oncology ward of the University Clinical Hospital in Niš and its connection to their marital status, age, level of education, economic status and the number of therapy cycles. This research is a prospective study. The statistical data analysis included measures of descriptive and analytical statistics. The presence of depressive symptoms of different intensity was showed in 76.00% of the interviewees in group I, and the second included 77.4%. The frequency distributions show that 27.084% interviewees from the first group showed signs of depressive symptoms, while the second included 25%. The intensity of these symptoms categorizes them into the group of moderate to significantly expressed depressive states, so they require therapeutic treatment. Depression is significantly more often recorded with cancer patients receiving cytotoxic therapy; mild depression is the most common, followed by moderate and severe depression. PMID:27138829

    Gene expression microarrays allow for the high throughput analysis of huge numbers of gene transcripts and this technology has been widely applied to the molecular and biological classification of cancer patients and in predicting clinical outcome. A potential handicap of such data intensive molecular technologies is the translation to clinical application in routine practice. In using an artificial neural network bioinformatic approach, we have reduced a 70 gene signature to just 9 genes capable of accurately predicting distant metastases in the original dataset. Upon validation in a follow-up cohort, this signature was an independent predictor of metastases free and overall survival in the presence of the 70 gene signature and other factors. Interestingly, the ANN signature and CA9 expression also split the groups defined by the 70 gene signature into prognostically distinct groups. Subsequently, the presence of protein for the principal prognosticator gene was categorically assessed in breast cancer tissue of an experimental and independent validation patient cohort, using immunohistochemistry. Importantly our principal prognosticator, CA9, showed that it is capable of selecting an aggressive subgroup of patients who are known to have poor prognosis. PMID:19347577

    An evolutionary programming (EP) technique was investigated to reduce the complexity of artificial neural network (ANN) models that predict the outcome of mammography-induced breast biopsy. By combining input variables consisting of mammography lesion descriptors and patient history data, the ANN predicted whether the lesion was benign or malignant, which may aide in reducing the number of unnecessary benign biopsies and thus the cost of mammography screening of breast cancer. The EP has the ability to optimize the ANN both structurally and parametrically. An EP was partially optimized using a data set of 882 biopsy-proven cases from Duke University Medical Center. Although many different architectures were evolved, the best were often perceptrons with no hidden nodes. A rank ordering of the inputs was performed using twenty independent EP runs. This confirmed the predictive value of the mass margin and patient age variables, and revealed the unexpected usefulness of the history of previous breast cancer. Further work is required to improve the performance of the EP over all cases in general and calcification cases in particular.

Cancer patients are occupied with many psychosocial problems, which are only partially related to their health state and medical treatments. They are faced with a high social pressure, based on prejudices and stereotypes of this illness. The review presents the process of confrontation with the cancer diagnosis and of managing the psychological consequences of cancer. The effects of specific coping styles, psychosocial interventions and a social support on initiation, progression and recurrence of cancer are also described. Conclusions. Although some recent meta-analysis could not provide scientific evidence for the association between coping strategies and the cancer initiation, the progression or the recurrence (neither have studies rejected the thesis of association), the therapeutic window for the psychosocial intervention is still wide and shows an important effect on the quality of lives of many cancer patients.

    Change in cell stiffness is a new characteristic of cancer cells that affects the way they spread. Despite several studies on architectural changes in cultured cell lines, no ex vivo mechanical analyses of cancer cells obtained from patients have been reported. Using atomic force microscopy, we report the stiffness of live metastatic cancer cells taken from the body (pleural) fluids of patients with suspected lung, breast and pancreas cancer. Within the same sample, we find that the cell stiffness of metastatic cancer cells is more than 70% softer, with a standard deviation over five times narrower, than the benign cells that line the body cavity. Different cancer types were found to display a common stiffness. Our work shows that mechanical analysis can distinguish cancerous cells from normal ones even when they show similar shapes. These results show that nanomechanical analysis correlates well with immunohistochemical testing currently used for detecting cancer.

  11. A Clinical Decision Support System for Breast Cancer Patients

    Science.gov (United States)

    Fernandes, Ana S.; Alves, Pedro; Jarman, Ian H.; Etchells, Terence A.; Fonseca, José M.; Lisboa, Paulo J. G.

    This paper proposes a Web clinical decision support system for clinical oncologists and for breast cancer patients making prognostic assessments, using the particular characteristics of the individual patient. This system comprises three different prognostic modelling methodologies: the clinically widely used Nottingham prognostic index (NPI); the Cox regression modelling and a partial logistic artificial neural network with automatic relevance determination (PLANN-ARD). All three models yield a different prognostic index that can be analysed together in order to obtain a more accurate prognostic assessment of the patient. Missing data is incorporated in the mentioned models, a common issue in medical data that was overcome using multiple imputation techniques. Risk group assignments are also provided through a methodology based on regression trees, where Boolean rules can be obtained expressed with patient characteristics.

    Full Text Available The free radical gene classification of cancer diseases is challenging job in biomedical data engineering. The improving of classification of gene selection of cancer diseases various classifier are used, but the classification of classifier are not validate. So ensemble classifier is used for cancer gene classification using neural network classifier with random forest tree. The random forest tree is ensembling technique of classifier in this technique the number of classifier ensemble of their leaf node of class of classifier. In this paper we combined neural network with random forest ensemble classifier for classification of cancer gene selection for diagnose analysis of cancer diseases. The proposed method is different from most of the methods of ensemble classifier, which follow an input output paradigm of neural network, where the members of the ensemble are selected from a set of neural network classifier. the number of classifiers is determined during the rising procedure of the forest. Furthermore, the proposed method produces an ensemble not only correct, but also assorted, ensuring the two important properties that should characterize an ensemble classifier. For empirical evaluation of our proposed method we used UCI cancer diseases data set for classification. Our experimental result shows that better result in compression of random forest tree classification.

    Oestrogen receptor (ER) expression is routinely measured in breast cancer management, but the clinical merits of measuring progesterone receptor (PR) expression have remained controversial. Hence the major objective of this study was to assess the potential of PR as a predictor of response to endocrine therapy. We report on analyses of the relative importance of ER and PR for predicting prognosis using robust multilayer perceptron artificial neural networks. Receptor determinations use immunohistochemical (IHC) methods or radioactive ligand binding assays (LBA). In view of the heterogeneity of intratumoral receptor distribution, we examined the relative merits of the IHC and LBA methods. Our analyses reveal a more significant correlation of IHC-determined PR than ER with both nodal status and 5-year disease-free survival (DFS). In LBA, PR displayed higher correlation with survival and ER with nodal status. There was concordance of correlation of PR with DFS by both IHC and LBA. This study suggests a clear distinction between PR and ER, with PR displaying greater correlation than ER with disease progression and prognosis, and emphasizes the marked superiority of the IHC method over LBA. These findings may be valuable in the management of patients with breast cancer. PMID:27069179

    This paper presents an analysis of censored survival data for breast cancer specific mortality and disease-free survival. There are three stages to the process, namely time-to-event modelling, risk stratification by predicted outcome and model interpretation using rule extraction. Model selection was carried out using the benchmark linear model, Cox regression but risk staging was derived with Cox regression and with Partial Logistic Regression Artificial Neural Networks regularised with Automatic Relevance Determination (PLANN-ARD). This analysis compares the two approaches showing the benefit of using the neural network framework especially for patients at high risk. The neural network model also has results in a smooth model of the hazard without the need for limiting assumptions of proportionality. The model predictions were verified using out-of-sample testing with the mortality model also compared with two other prognostic models called TNG and the NPI rule model. Further verification was carried out by comparing marginal estimates of the predicted and actual cumulative hazards. It was also observed that doctors seem to treat mortality and disease-free models as equivalent, so a further analysis was performed to observe if this was the case. The analysis was extended with automatic rule generation using Orthogonal Search Rule Extraction (OSRE). This methodology translates analytical risk scores into the language of the clinical domain, enabling direct validation of the operation of the Cox or neural network model. This paper extends the existing OSRE methodology to data sets that include continuous-valued variables. PMID:18304780

    Islamic healing is frequently referred to as the treatment of choice by many Muslim cancer patients in Malaysia. Despite its widespread use, there is limited information relating to patients' healing preferences. With rising cancer rates in the country, this issue has become a concern to public health policy makers. The purpose of this study was to understand why cancer patients seek Islamic healing. This qualitative study utilized in-depth interviews with 18 cancer patients. The findings indicate three main reasons: (1) recommendations from family, friends and doctors; (2) belief in Islamic healing and (3) the perceived ineffectiveness and dissatisfaction with conventional treatments. Islamic healing will likely continue to be popular complementary cancer treatment in Malaysia as it is grounded in strong cultural and religious beliefs. PMID:26391242

    The goal of this review is to discuss the psychiatric aspects of pain in cancer patients from a biopsychosocial approach. Pain in cancer patients is considered as a complex reaction causing severe suffering and involves many psychological aspects. It has many dimensions such as personality, affect, cognition and social relations. The pain experience may also be influenced by some psychological factors such as anxiety, depression and the meaning of pain. Therefore, a successful management of cancer pain requires a multidisciplinary approach. Since cancer pain is generally treated medically, the psychological impact of pain is often underestimated. However, cancer pain is usually related to high levels of psychological distress. Culture, as an important factor affecting cancer pain, will also be discussed during this review. It is crucial to understand cultural diversity in the treatment of cancer patients with pain. Research shows that a minority patients of various ethnicities have less control of their pain because of the miscommunication problem within the medical setting. By paying attention to patients' cultural diversities, problems such as miscommunication causing inadequate control of pain can be eliminated. In order to manage pain in cancer patients, cognitive-behavioral interventions may be integrated with pharmacotherapy. The main goal of these strategies is to provide a sense of control and better coping skills to deal with cancer. Patients' maladaptive thoughts or behaviors may cause physical and emotional stress. Main behavioral strategies include biofeedback, relaxation training, and hypnosis. Cognitive strategies include guided imagery, distraction, thought monitoring and problem solving. By discussing all of these aspects of cancer pain, the multidimensional characteristic of pain and the relation between cancer pain and psychiatric factors will be clarified. PMID:20590361

    Full Text Available Aims: To determine the level of oral cancer awareness and knowledge among patients referred to the Department of Oral and Maxillofacial Radiology in Central Anatolia. Settings and Design: The study was conducted with 1,125 patients who applied to the school of dentistry for routine dental examinations. The authors collect information with a 20-item written questionnaire from the participants about oral cancer risk factors, epidemiology, etiology, and signs and symptoms. Statistical Analysis: Descriptive statistics of demographic variables and other data were reported as means and percentages. Statistical analysis was performed by means of SPSS +11.0 statistical package. Results: Overall, only 48.9% of all patients showed awareness of oral cancer, with awareness especially poor among lower socioeconomic groups. Awareness of oral cancer risk factors and signs and symptoms did not vary significantly between men and women (P > 0.5; however, older participants (aged 40-64 years were more familiar with oral cancer signs than younger participants. More than half of all participants (56.8% were unaware of the common clinical presentations of oral cancer. Conclusions: The results of this survey showed knowledge regarding oral cancer to be quite low. Thus, educational programs are needed to increase public awareness about oral cancer, and dentists should request patients undergo examinations for oral cancer to ensure early detection.

    Full Text Available Abstract Cancer patients experience several stressors and emotional upheavals. Fear of death, interruption of life plans, changes in body image and self-esteem, changes in social role and lifestyle are all important issues to be faced. Moreover, Depressive Disorders may impact the course of the disease and compliance. The cost and prevalence, the impairment caused, and the diagnostic and therapeutic uncertainty surrounding depressive symptoms among cancer patients make these conditions a priority for research. In this article we discuss recent data, focusing on detection of Depressive Disorders, biological correlates, treatments and unmet needs of depressed cancer patients.

  6. Artificial neural networks for processing fluorescence spectroscopy data in skin cancer diagnostics

    International Nuclear Information System (INIS)

    Over the years various optical spectroscopic techniques have been widely used as diagnostic tools in the discrimination of many types of malignant diseases. Recently, synchronous fluorescent spectroscopy (SFS) coupled with chemometrics has been applied in cancer diagnostics. The SFS method involves simultaneous scanning of both emission and excitation wavelengths while keeping the interval of wavelengths (constant-wavelength mode) or frequencies (constant-energy mode) between them constant. This method is fast, relatively inexpensive, sensitive and non-invasive. Total synchronous fluorescence spectra of normal skin, nevus and melanoma samples were used as input for training of artificial neural networks. Two different types of artificial neural networks were trained, the self-organizing map and the feed-forward neural network. Histopathology results of investigated skin samples were used as the gold standard for network output. Based on the obtained classification success rate of neural networks, we concluded that both networks provided high sensitivity with classification errors between 2 and 4%. (paper)

    The scope of supportive care and cancer rehabilitation is very wide and heterogeneous. In this review we focus on nutritional aspects, sexual and gonadal function, psychological rehabilitation, treatment of cancer pain, and rehabilitation of patients with bone metastases. The anorexia-cachexia syndrome is a particularly frequent manifestation of cancer that profoundly affects body image and significantly impairs quality of life of cancer patients. However, enteral feeding through nasogastric tubes, gastrostomies, or jejunostomies is an efficient method for providing long-term enteral nutrition at home and for contributing to complete rehabilitation after cancer therapy. Recent effort has focused on nutritional pharmacology and on the optimalization of the use of appetite-stimulating drugs, such as progestational agents. The psychological components of cancer, anticancer therapy, and quality of life have now been widely recognized and studied. Effective pharmacological and psychotherapeutic interventions help patients and their family to better adjust to the chronic stress of cancer, but more specific determinants of psychological morbidity should be developed. In particular, the safe and efficient use of the most recent classes of antidepressants and anxiolytics should be urgently studied. More than 90% of cancer patients present one or more pain syndromes during their illness. The adequate use of drugs is the cornerstone of treatment. The development on new molecules and new routes of administration opens interesting perspectives for cancer pain control. Bone metastases are the source of considerable morbidity. Intravenous bisphosphonates have been successfully used for the treatment of the symptoms of metastatic bone disease, especially bone pain. Moreover, monthly pamidronate infusions in addition to chemotherapy reduce the mean skeletal morbidity rate by more than one third and contribute to the rehabilitation of cancer patients with bone metastases from breast

There is paucity of data on the prevalence of malnutrition in pediatric cancer patients and the impact of cancer treatment on nutritional status of Indian children. Aims: The study was conducted to look at the prevalence of malnutrition and assess the impact of treatment on nutritional status of pediatric cancer patients. Settings And Design: This was a retrospective study. Materials And Methods: Data on the weight of pediatric cancer patients <16 years of age treated at Cancer Institute, Chennai, from January 2013 to May 2014 were analyzed at systematic time points in therapy. Patients' weight were plotted on the Centre for Disease Control (CDC growth charts. Patients were defined to be undernourished if their weight for age was ≤3rd centile in CDC growth charts and obese if their weight for age was ≥97th centile on CDC growth charts. RESULTS: A total of 295 patient case records were analyzed. Acute lymphoblastic leukemia was the most common malignancy. At diagnosis, under-nutrition was seen in 44% patients, this increased to 46% midway during treatment (end of induction in acute leukemia and completion of 50% of planned treatment in solid tumors and decreased to 27% at the end of treatment (beginning of maintenance in acute leukemia and completion of planned treatment in solid tumors (P = 0.0005. There was no significant difference in nutritional status between patients with hematological malignancies and solid tumors (P = 0.8. Conclusion: Under-nutrition is present in close to half of the pediatric cancer patients presenting to our institute. Active nutritional intervention and education were able to significantly reduce the prevalence of under-nutrition in patients at the end of treatment.

    AIM: To identify patients with a high-risk of having a synchronous cancer among gastric cancer patients.METHODS: We retrospectively analyzed the prospective gastric cancer database at the National Cancer Center,Korea from December 2000 to December 2004. The clinicopathological characteristics of patients with synchronous cancers and those of patients without synchronous cancers were compared. Multivariate analysis was performed to identify the risk factors for the presence of a synchronous cancer in gastric cancer patients.RESULTS: 111 of 3291 gastric cancer patients (3.4%)registered in the database had a synchronous cancer.Among these 111 patients, 109 had a single synchronous cancer and 2 patients had two synchronous cancers. The most common form of synchronous cancer was colorectal cancer (42 patients, 37.2%) followed by lung cancer (21 patients, 18.6%). Multivariate analyses revealed that elderly patients with differentiated early gastric cancer have a higher probability of a synchronous cancer.CONCLUSION: Synchronous cancers in gastric cancer patients are not infrequent. The physicians should try to find synchronous cancers in gastric cancer patients,especially in the elderly with a differentiated early gastric cancer.

  15. Second cancers in patients with neuroendocrine tumors.

    Directory of Open Access Journals (Sweden)

    Hui-Jen Tsai

    Full Text Available BACKGROUND: Second cancers have been reported to occur in 10-20% of patients with neuroendocrine tumors (NETs. However, most published studies used data from a single institution or focused only on specific sites of NETs. In addition, most of these studies included second cancers diagnosed concurrently with NETs, making it difficult to assess the temporality and determine the exact incidence of second cancers. In this nationwide population-based study, we used data recorded by the Taiwan Cancer Registry (TCR to analyze the incidence and distribution of second cancers after the diagnosis of NETs. METHODS: NET cases diagnosed from January 1, 1996 to December 31, 2006 were identified from the TCR. The data on the occurrence of second cancers were ascertained up to December 31, 2008. Standardized incidence ratios (SIRs of second cancers were calculated based on the cancer incidence rates of the general population. Cox-proportional hazards regression analysis was performed to estimate the hazard ratio (HR and 95% confidence interval (CI for the risk of second cancers associated with sex, age, and primary NET sites. RESULTS: A total of 1,350 newly diagnosed NET cases were identified according to the selection criteria. Among the 1,350 NET patients, 49 (3.63% developed a second cancer >3 months after the diagnosis of NET. The risk of second cancer following NETs was increased compared to the general population (SIR = 1.48, 95% CI: 1.09-1.96, especially among those diagnosed at age 70 or older (HR = 5.08, 95% CI = 1.69-15.22. There appeared to be no preference of second cancer type according to the primary sites of NETs. CONCLUSIONS: Our study showed that the risk of second cancer following NETs is increased, especially among those diagnosed at age 70 or older. Close monitoring for the occurrence of second cancers after the diagnosis of NETs is warranted.

    The aim was to describe male cancer survivors' barriers towards participation in cancer rehabilitation as a means to guiding future targeted men's cancer rehabilitation. Symbolic Interactionism along with the interpretive descriptive methodology guided the study of 35 male cancer survivors representing seven cancer types. Data were generated through a 5-month fieldwork study comprising participant observations, semi-structured individual interviews and informal conversations. The analyses revealed two overarching findings shedding light on male cancer survivors' barriers to rehabilitation: 'Fear of losing control' and 'Striving for normality'. While 'Fear of losing control' signified what the men believed rehabilitation would invoke: 'Reduced manliness', 'Sympathy and dependency' and 'Confrontation with death', 'Striving for normality' was based on what the men believed rehabilitation would hinder: 'Autonomy and purpose', 'Solidarity and fellowship' and 'Forget and move on'. This study of male cancer survivors' and cancer rehabilitation documents how masculine ideals may constitute barriers for participation in rehabilitation and provides insights about why men are underrepresented in rehabilitation. The findings can guide practice to develop research-based rehabilitation approaches focused on preserving control and normality. Further empirical evidence is needed to: (1) explore the conduct of health professionals' towards male cancer patients and (2) address gender inequalities in cancer rehabilitation. PMID:26223855

    Breast cancer is the most prevalent malignancy among women under 50. Improvements in diagnosis and treatment have yielded an important decrease in mortality in the last 20 years. In many cases, chemotherapy and radiotherapy develop side effects on the reproductive function. Therefore, before the anti-cancer treatment impairs fertility, clinicians should offer some techniques for fertility preservation for women planning motherhood in the future. In order to obtain more available oocytes for IVF, the ovary must be stimulated. New protocols which prevent exposure to increased estrogen during gonadotropin stimulation, measurements to avoid the delay in starting anti-cancer treatment or the outcome of ovarian stimulation have been addressed in this review. There is no evidence of association between ovarian stimulation and breast cancer. It seems that there are more relevant other confluent factors than ovarian stimulation. Factors that can modify the risk of breast cancer include: parity, age at full-term birth, age of menarche, and family history. There is an association between breast cancer and exogenous estrogen. Therefore, specific protocols to stimulate patients with breast cancer include anti-estrogen agents such as letrozole. By using letrozole plus recombinant follicular stimulating hormone, patients develop a multifollicular growth with only a mild increase in estradiol serum levels. Controlled ovarian stimulation (COS) takes around 10 days, and we discuss new strategies to start COS as soon as possible. Protocols starting during the luteal phase or after inducing the menses currently prevent a delay in starting ovarian stimulation. Patients with breast cancer have a poorer response to COS compared with patients without cancer who are stimulated with conventional protocols of gonadotropins. Although many centres offer fertility preservation and many patients undergo ovarian stimulation, there are not enough studies to evaluate the recurrence, breast cancer

    Full Text Available Breast cancer is the second leading cause of death for women all over the world. The correct diagnosis of breast cancer is one of the major problems in the medical field. From the literature it has been found that different pattern recognition techniques can help them to improve in this domain. This paper presents a novel hybrid intelligent method for detection of breast cancer. The proposed method includes two main modules: Clustering module and the classifier module. In the clustering module, first the input data will be clustered by a new technique. This technique is a suitable combination of the modified imperialist competitive algorithm (MICA and K-means algorithm. Then the Euclidean distance of each pattern is computed from the determined clusters. The classifier module determines the membership of the patterns using the computed distance. In this module, several neural networks, such as the multilayer perceptron, probabilistic neural networks and the radial basis function neural networks are investigated. Using the experimental study, we choose the best classifier in order to recognize the breast cancer. The proposed system is tested on Wisconsin Breast Cancer (WBC database and the simulation results show that the recommended system has high accuracy.

    Full Text Available Introduction: Being a cancer patient is a unique and singular. The cancer disease associated with pain and suffering is a challenging process for the sufferer, for whom have around or for those caring for the sick. Pain, considered the 5 th vital sign, is often identified as the main complaint of our patients suffering from cancer. We dare to say that to explore the essence of the care provided by nurses and primary health care to cancer patients with prolonged pain at the time found in his home and family, we would be helping to build a know -how by itself, with positive externalities for patients, families, professionals and nursing itself. Methods: Ask "What does Care for Nurses and primary health care for cancer patients with prolonged pain in time for your family?" we may lead the cornerstone of our problems, by studying quantitative nature using a questionnaire and a significance level of care. Results: the average age is 59.27 years, mostly women, 51% are married and in 29.8% of studies has only completed the first cycle of education. The majority of cancer patients who participated in this study share a room with a relative. In regard to aspects of their pain, cancer patients referred to 47.1% of cases, that their pain started weeks ago and 38.5% even refers to the pain persists for months. The pain felt by these patients is not the severe type, in 68.3% of cases, and has an average intensity of 5, although we have 25% of these patients with pain greater than a 6.75. The Meaning of Caring scale applied to the group of nurses who provide care at primary health reveals an alpha of 0.8857 and 0.9025 standardized alpha. The Meaning of Caring scale applied to the group of cancer patients with prolonged pain at the time they are at home shows an alpha of 0.6672and 0.7374 standardized alpha. The Meaning of Caring scale applied to the group of cancer family patients with prolonged pain shows an alpha of 0.6712 and an alpha standardized 0

    Kim, Chung-Hoon; Jeon, Gyun-Ho

    2012-01-01

    With improved survival rates among cancer patients, fertility preservation is now being recognized as an issue of great importance. There are currently several methods of fertility preservation available in female cancer patients and the options and techniques via assisted reproduction and cryopreservation are increasing, but some are still experimental and continues to be evaluated. The established means of preserving fertility include embryo cryopreservation, gonadal shielding during radiation therapy, ovarian transposition, conservative gynecologic surgery such as radical trachelectomy, donor embryos/oocytes, gestational surrogacy, and adoption. The experimental methods include oocyte cryopreservation, ovarian cryopreservation and transplantation, in vitro maturation, and ovarian suppression. With advances in methods for the preservation of fertility, providing information about risk of infertility and possible options of fertility preservation to all young patients with cancer, and discussing future fertility with them should be also considered as one of the important parts of consultation at the time of cancer diagnosis.

Clinical data of the patients hospitalized for lung cancer were analyzed at the Clinic for Lung Diseases and Tuberculosis in Knez Selo in the period from January 2002 till December 2007. A great number of patients (1296-75.9% had non-small cell lung cancer. In 1708 patients with lung cancer, 773 febrile episodes were recorded, i.e. 687 states of infections. Results. Most of the infections were recorded in the tracheobronchial tree (60.9%. The infection was confirmed microbiologically in 38% of infectious states. Predominant Gram positive pathogens were Staphylococcus aureus and Streptococcus, but among Gram negative pathogens there were Escherichia coli and Haemophilus influenzae. Discussion. A significantly better therapy response to antibiotics was found in the group of patients where microbiological agents were isolated (p<0.05. The predominant site of infection in the patients with lung cancer is the tracheobronchial tree without a significant difference between frequency of Gram positive and Gram negative pathogens.

    Patients with esophageal cancer have a poor prognosis because they often have no symptoms until their disease is advanced.There are no screening recommendations for patients unless they have Barrett's esophagitis or a significant family history of this disease.Often,esophageal cancer is not diagnosed until patients present with dysphagia,odynophagia,anemia or weight loss.When symptoms occur,the stage is often stage Ⅲ or greater.Treatment of patients with very early stage disease is fairly straight forward using only local treatment with surgical resection or endoscopic mucosal resection.The treatment of patients who have locally advanced esophageal cancer is more complex and controversial.Despite multiple trials,treatment recommendations are still unclear due to conflicting data.Sadly,much of our data is difficult to interpret due to many of the trials done have included very heterogeneous groups of patients both histologically as well as anatomically.Additionally,studies have been underpowered or stopped early due to poor accrual.In the United States,concurrent chemoradiotherapy prior to surgical resection has been accepted by many as standard of care in the locally advanced patient.Patients who have metastatic disease are treated palliatively.The aim of this article is to describe the multidisciplinary approach used by an established team at a single high volume center for esophageal cancer,and to review the literature which guides our treatment recommendations.

    Pain in patients with cancer can be refractory to pharmacological treatment or intolerable side effects of pharmacological treatment may seriously disturb patients' quality of life. Specific interventional pain management techniques can be an effective alternative for those patients. The appropriate application of these interventional techniques provides better pain control, allows the reduction of analgesics and hence improves quality of life. Until recently, the majority of these techniques are considered to be a fourth consecutive step following the World Health Organization's pain treatment ladder. However, in cancer patients, earlier application of interventional pain management techniques can be recommended even before considering the use of strong opioids. Epidural and intrathecal medication administration allow the reduction of the daily oral or transdermal opioid dose, while maintaining or even improving the pain relief and reducing the side effects. Cervical cordotomy may be considered for patients suffering with unilateral pain at the level below the dermatome C5. This technique should only be applied in patients with a life expectancy of less than 1 year. Plexus coeliacus block or nervus splanchnicus block are recommended for the management of upper abdominal pain due to cancer. Pelvic pain due to cancer can be managed with plexus hypogastricus block and the saddle or lower end block may be a last resort for patients suffering with perineal pain. Back pain due to vertebral compression fractures with or without pathological tumor invasion may be managed with percutaneous vertebroplasty or kyphoplasty. All these interventional techniques should be a part of multidisciplinary patient program. PMID:21679293

    Patients not older than 40 years are referred to as young patients. These women benefit from chemo-, endocrine and anti-HER2 therapy to a similar degree as older women. Surgery and radiation therapy also follow the same recommendations. This manuscript deals with the following topics that need special consideration in young women: endocrine therapy and ovarian suppression; fertility protection and family planning; and genetic counselling. There is an on-going debate on whether tamoxifen is sufficient as an endocrine treatment in young patients with endocrine-responsive tumours or whether suppression of ovarian function in combination with tamoxifen or aromatase inhibitor should be preferred. Recent data suggest a benefit from ovarian suppression plus exemestane in women of 35 years or younger with high-risk breast cancer. However, increased side effects bear the risk of lesser compliance, which eventually results in higher mortality. Child bearing is nowadays frequently postponed to the 4th decade of life, thereby increasing the number of women who have not yet finished their reproductive desires when diagnosed with breast cancer. These patients are in urgent need of counselling for fertility protection. Breast cancer diagnosis at young age is an indication for a possible mutation in breast cancer susceptibility genes. This has an impact on the cancer risk of the whole family, especially the offspring. Drugs that are specifically targeted to cancer cells with genetic alterations that impair DNA repair are already entering the arsenal of oncologists. PMID:27031253

    Full Text Available As a result of advances in treatment, almost 80% of children and adolescents who receive a diagnosis of cancer become long-term survivors. The increased survival rate of children and adolescents with cancer has resulted in a major interest in the long-term effects of cancer treatment on the possibility for future fertility. Currently established methods for the preservation of fertility are available only for pubertal males and females. Pubertal male cancer patients should be encouraged to freeze numerous sperm samples even when sperm count and motility are poor. In these cases, intracytoplasmic sperm injection is a powerful technique compared with intrauterine insemination since thawed sperm samples with poor parameters can produce relatively high fertilization rates resulting in normal pregnancies and deliveries. Married pubertal women should be proposed ovulation induction, follicular aspiration, and fertilization with husband sperm. Single women could benefit from vitrification of oocytes. This requires a delay of about 3 weeks in the commencement of chemotherapy to enable follicular growth. Fertility preservation for prepubertal patients is more of a problem. Young girls could be offered cryopreservation of gametes in the gonadal tissue. Cryopreservation of testicular tissue was suggested for fertility preservation for young boys, but this method is totally experimental and not currently offered. Discussing future fertility is part of the consultation of young female and male patients facing potentially gonadotoxic cancer therapy. It is the role of reproductive specialists to create various options in their laboratory to preserve fertility potential of cancer patients.

    Human kallikrein 11 (hK11) was evaluated in a percentage free PSA-based artificial neural network (ANN) to reduce unnecessary prostate biopsies. Serum samples from 357 patients with (n=132) and without (n=225) prostate cancer (PCa) were analyzed and ANN models were constructed and compared to all parameters. The discriminatory power of hK11 was lower than that of PSA, but receiver operator characteristic (ROC) analyses demonstrated significantly larger areas under the curves for the ANN compared to all other parameters. ANNs with hK11 may lead to a further reduction in unnecessary prostate biopsies, especially when analyzing patients with less than 15% free PSA. PMID:16800743

    Full Text Available Although neural network models for cancer chemotherapy have been analyzed since the early seventies, less research has been done in actually formulating them as optimal control problems. In this paper an artificial neural networks-based method for optimal control of bone marrow in cell-cycle-specific chemotherapy is proposed. In this method, we use artificial neural networks for approximating the optimal control problem which maximizes both bone marrow mass and drug`s dose at the same time. The corresponding model be transfer to Hamiltonian function and using Pontryagin principle we create the boundary conditions. After defining boundary conditions, we use the approximating property of artificial networks and put the boundary conditions in error functions to satisfy the limitations..

    Although palliative care has been developed and implemented as care for cancer pain, it is holistic care for suffering that includes physical, psychosocial and spiritual pain of life-threatening illness. It turned out that non-cancer patients in the end-stage are also suffering from various pain that should be treated as cancer patients. Trajectories of illness in non-cancer patients are with more gradual decline than those of cancer patients with steady progression and it is often difficult to make decision about end-of-life. The purpose of advance care planning was originally to help describe legal documents. This process is proved to contribute to improving QOL of patients and their families to discuss preference, hope, economic problems, spiritual question as well as medical treatment In Japan guideline of decision making process in end-of-life stage has been established. A program of communication training in end-of-life discussion has been made. Under current situation some comments on the role of anesthesiologists are also mentioned. PMID:27097506

    Full Text Available Morphine is one of the most potent alkaloid in opium, which has substantial medical uses and needs and it is the first active principle purified from herbal source. Morphine has commonly been used for relief of moderate to severe pain as it acts directly on the central nervous system; nonetheless, its chronic abuse increases tolerance and physical dependence, which is commonly known as opiate addiction. Morphine withdrawal syndrome is physiological and behavioral symptoms that stem from prolonged exposure to morphine. A majority of brain regions are hypofunctional over prolonged abstinence and acute morphine withdrawal. Furthermore, several neural mechanisms are likely to contribute to morphine withdrawal. The present review summarizes the literature pertaining to neural mechanisms underlying morphine withdrawal. Despite the fact that morphine withdrawal is a complex process, it is suggested that neural mechanisms play key roles in morphine withdrawal.

    Combined PET/MRI systems are now commercially available and are expected to change the medical imaging field by providing combined anato-metabolic image information. We believe this will be of particular relevance in imaging of cancer patients.

    1998-11-01

    Cancer presents itself in numerous ways, adding to the complexity of any pain syndrome with which it is associated. Neuropathic pain, unlike many other pain syndromes, is difficult to treat even in the absence of cancer. The combination results in a heterogeneous group of patients with a complex set of symptoms. This makes the assessment of pain, classification of syndromes, and clinical study a challenge. If the disease is nonprogressive, general principles of care are essentially the same as in those without cancer. In patients with progressive disease and more refractory painful conditions, spinal anesthetic and neurosurgical therapies must often be considered. Under such circumstances, caregivers are forced to carefully balance uncertain benefits and risks, often without the luxury of time. More careful observation and controlled trials in these patients help facilitate this challenging process. PMID:9767067

    Full Text Available Negative emotions (distress are recognized as part of the psychological profile of patients diagnosed with advanced stage cancer. However, most patients are not accustomed to verbalize feelings towards their physician, and generally towards family and medical care personnel. The purpose of this paper is to analyze the expression of emotions by patients in advanced stages of cancer, respectively the means by which they get to express emotions. To this respect, we identified the most common types of emotions expressed, or metaphors used by patients to describe their emotions and topics that trigger emotions. Words and phrases most commonly used are in relation to: fear, anxiety, depression, guilt, negligence, concern. They are uttered in order to depict the network created between disclosed emotions and topics on health status, symptoms, adverse effects and therapeutic choice, patient privacy, and social and family issues.

    In recent years there have been major advances in the treatment of breast cancer. However, taking the prescribed medication for a sufficient period of time is crucial to the success of any therapy. Thus far, no database-based studies have been published in German-speaking countries empirically examining the influence of the physician on the compliance of patients. The aim of this study is to investigate, quantify, and critically discuss the effect treating physicians have on the compliance of their breast cancer patients. Patients with a confirmed breast cancer diagnosis who started therapy (tamoxifen or aromatase inhibitors) between January 2001 and December 2011 were selected from the representative IMS Disease Analyzer database and analyzed with regard to their compliance. Practices were grouped into two categories concerning the compliance of all treated patients. A regression model showed that a breast cancer patient who is treated in a practice with a trend toward poor compliance has a nearly 60% higher risk for treatment discontinuation than would be the case in a practice with good compliance. It shows how important it is to motivate physicians to strive toward good compliance rates. PMID:24454275

    2015-12-01

    Renal cancer occurs more frequently in renal transplanted patients than in the general population, affecting native kidneys in 90% of cases and the graft in 10 %. In addition to general risk factors, malignancy susceptibility may be influenced by immunosuppressive therapy, the use of calcineurin inhibitors (CNI) as compared with mammalian target of rapamycin inhibitors, and the length of dialysis treatment. Acquired cystic kidney disease may increase the risk for renal cancer after transplantation, while autosomal dominant polycystic kidney disease does not seem to predispose to cancer development. Annual ultrasound evaluation seems appropriate in patients with congenital or acquired cystic disease or even a single cyst in native kidneys, and every 2 years in patients older than 60 years if they were on dialysis for more than 5 years before transplantation. Immunosuppression should be lowered in patients who develop renal cancer, by reduction or withdrawal of CNI. Although more evidence is still needed, it seems reasonable to shift patients from CNI to everolimus or sirolimus if not already treated with one of these drugs, with due caution in subjects with chronic allograft nephropathy.

  9. Cachexia in patients with oesophageal cancer.

    Anandavadivelan, Poorna; Lagergren, Pernilla

    2016-03-01

    Oesophageal cancer is a debilitating disease with a poor prognosis, and weight loss owing to malnutrition prevails in the majority of patients. Cachexia, a multifactorial syndrome characterized by the loss of fat and skeletal muscle mass and systemic inflammation arising from complex host-tumour interactions is a major contributor to malnutrition, which is a determinant of tolerance to treatment and survival. In patients with oesophageal cancer, cachexia is further compounded by eating difficulties owing to the stage and location of the tumour, and the effects of neoadjuvant therapy. Treatment with curative intent involves exceptionally extensive and invasive surgery, and the subsequent anatomical changes often lead to eating difficulties and severe postoperative malnutrition. Thus, screening for cachexia by means of percentage weight loss and BMI during the cancer trajectory and survivorship periods is imperative. Additionally, markers of inflammation (such as C-reactive protein), dysphagia and appetite loss should be assessed at diagnosis. Routine assessments of body composition are also necessary in patients with oesophageal cancer to enable assessment of skeletal muscle loss, which might be masked by sarcopenic obesity in these patients. A need exists for clinical trials examining the effectiveness of therapeutic and physical-activity-based interventions in mitigating muscle loss and counteracting cachexia in these patients.

  10. Anemia, tumor hypoxemia, and the cancer patient

    International Nuclear Information System (INIS)

    Purpose: To review the impact of anemia/tumor hypoxemia on the quality of life and survival in cancer patients, and to assess the problems associated with the correction of this difficulty. Methods: MEDLINE searches were performed to find relevant literature regarding anemia and/or tumor hypoxia in cancer patients. Articles were evaluated in order to assess the epidemiology, adverse patient effects, anemia correction guidelines, and mechanisms of hypoxia-induced cancer cell growth and/or therapeutic resistance. Past and current clinical studies of radiosensitization via tumor oxygenation/hypoxic cell sensitization were reviewed. All clinical studies using multi-variate analysis were analyzed to show whether or not anemia and/or tumor hypoxemia affected tumor control and patient survival. Articles dealing with the correction of anemia via transfusion and/or erythropoietin were reviewed in order to show the impact of the rectification on the quality of life and survival of cancer patients. Results: Approximately 40-64% of patients presenting for cancer therapy are anemic. The rate of anemia rises with the use of chemotherapy, radiotherapy, and hormonal therapy for prostate cancer. Anemia is associated with reductions both in quality of life and survival. Tumor hypoxemia has been hypothesized to lead to tumor growth and resistance to therapy because it leads to angiogenesis, genetic mutations, resistance to apoptosis, and a resistance to free radicals from chemotherapy and radiotherapy. Nineteen clinical studies of anemia and eight clinical studies of tumor hypoxemia were found that used multi-variate analysis to determine the effect of these conditions on the local control and/or survival of cancer patients. Despite differing definitions of anemia and hypoxemia, all studies have shown a correlation between low hemoglobin levels and/or higher amounts of tumor hypoxia with poorer prognosis.

  12. Fertility preservation in young patients with cancer

    2015-01-01

    Full Text Available Infertility can arise as a consequence of treatment of oncological conditions. The parallel and continued improvement in both the management of oncology and fertility cases in recent times has brought to the forefront the potential for fertility preservation in patients being treated for cancer. Many survivors will maintain their reproductive potential after the successful completion of treatment for cancer. However total body irradiation, radiation to the gonads, and certain high dose chemotherapy regimens can place women at risk for acute ovarian failure or premature menopause and men at risk for temporary or permanent azoospermia. Providing information about risk of infertility and possible interventions to maintain reproductive potential are critical for the adolescent and young adult population at the time of diagnosis. There are established means of preserving fertility before cancer treatment; specifically, sperm cryopreservation for men and in vitro fertilization and embryo cryopreservation for women. Several innovative techniques are being actively investigated, including oocyte and ovarian follicle cryopreservation, ovarian tissue transplantation, and in vitro follicle maturation, which may expand the number of fertility preservation choices for young cancer patients. Fertility preservation may also require some modification of cancer therapy; thus, patients' wishes regarding future fertility and available fertility preservation alternatives should be discussed before initiation of therapy.

    Full Text Available Purpose: Several studies have shown that HIV patients are at higher risk of lung cancer. Our aim is to analyse the prevalence and features of lung cancer in HIV-infected patients. Methods: The clinical charts of 4,721 HIV-infected patients seen in three hospitals of southeast Spain (study period 1992–2012 were reviewed, and all patients with a lung cancer were analysed. Results: There were 61 lung cancers, giving a prevalence of 1.2%. There was a predominance of men (82.0%, and smokers (96.6%; mean pack-years 35.2, with a median age of 48.0 (41.7–52.9 years, and their distribution according to risk group for HIV was: intravenous drug use 58.3%, homosexual 20.0%, and heterosexual 16.7%. Thirty-four (56.7% patients were Aids cases, and 29 (47.5% had prior pulmonar events: tuberculosis 16, bacterial pneumonia 9, and P. jiroveci pneumonia 4. The median nadir CD4 count was 149/mm3 (42–232, the median CD4 count at the time of diagnosis of the lung cancer was 237/mm3 (85–397, and 66.1%<350/mm3. 66.7% were on ART, and 70% of them had undetectable HIV viral load. The most common histological types of lung cancer were adenocarcinoma and epidermoid, with 24 (40.0% and 23 (38.3% cases, respectively. There were 49 (80.3% cases with advanced stages (III and IV at diagnosis.

    Evidence shows that continued smoking by cancer patients leads to adverse treatment outcomes and affects survival. Smoking diminishes treatment effectiveness, exacerbates side effects, and increases the risk of developing additional complications. Patients who continue to smoke also have a higher risk of developing a second primary cancer or experiencing a cancer recurrence, both of which ultimately contribute to poorer quality of life and poorer survival. Here, we present a snapshot of smoking behaviours of current cancer patients compared with the non-cancer patient population in Canada. Minimal differences in smoking behaviours were noted between current cancer patients and the rest of the population. Based on 2011–2014 data from the Canadian Community Health Survey, 1 in 5 current cancer patients (20.1%) reported daily or occasional smoking. That estimate is comparable to findings in the surveyed non-cancer patient population, of whom 19.3% reported smoking daily or occasionally. Slightly more male cancer patients than female cancer patients identified as current smokers. A similar distribution was observed in the non-cancer patient population. There is an urgent need across Canada to better support cancer patients in quitting smoking. As a result, the quality of patient care will improve, as will cancer treatment and survival outcomes, and quality of life for these patients.

    When doctors see more cases of patients with tell-tale symptoms of a disease, it is hoped that they will be able to recognize an infection administer treatment appropriately, thereby speeding up recovery for sick patients. We hope that our studies can aid in the detection of tuberculosis by using a computer model called an artificial neural network. Our model looks at patients with and without tuberculosis (TB). The data that the neural network examined came from the following: patient' age, gender, place, of birth, blood type, Rhesus (Rh) factor, and genes of the human Leukocyte Antigens (HLA) system (9q34.1) present in the Major Histocompatibility Complex. With availability in genetic data and good research, we hope to give them an advantage in the detection of tuberculosis. We try to mimic the doctor's experience with a computer test, which will learn from patient data the factors that contribute to TB.

    Full Text Available The present study intended to evaluate the nutritional status of Portuguese colorectal patients and associated it with surgery type as well as quality of life outcomes. Malnutrition can affect up to 85% of cancer patients and specifically 30-60% in colorectal cancer and can significantly influence health outcomes. A sample of 50 colorectal cancer patients was evaluated in what refers to several anthropometric measures, food intake, clinical history, complications rate before and after surgery procedure. The sample was divided between convention and fast-track procedures. Most of the individuals were overweight or obese but had lost weight on the past six months. Despite mild, there were signs of malnutrition in this sample with high losses of fat free mass, weight and also fat mass during the hospitalization period. These results reinforce the importance of malnutrition assessment in colorectal patients as well as consider weight loss on the past months and body composition in order to complement nutritional status evaluation.

    Treatment for prostate cancer (PCa) has evolved significantly over the last decade. PCa is the most prevalent non-skin cancer and the second leading cause of cancer death in men, and it has an increased incidence and prevalence in older men. As a result, physicians and patients are faced with the challenge of identifying optimal treatment strategies for localized, biochemical recurrent, and advanced PCa in the older population. When older patients are appropriately selected, treatment for PCa results in survival benefits and toxicity profiles similar to those experienced in younger patients. However, underlying health status and age-related changes can have an impact on tolerance of hormonal therapy and chemotherapy in men with advanced disease. Therefore, the heterogeneity of the elderly population necessitates a multidimensional assessment to maximize the benefit of medical and/or surgical options. Providing clinicians with the requisite health status data on which to base treatment decisions would help ensure that older patients with PCa receive optimal therapy if it will benefit them and/or active surveillance or best supportive care if it will not. We provide a review of the existing evidence to date on the management of PCa in the older population. PMID:25071137

    CD11b(+)Gr-1(+) myeloid-derived suppressor cells (MDSCs) expand in the spleen during cancer and promote progression through suppression of cytotoxic T cells. An anti-inflammatory reflex arc involving the vagus nerve and memory T cells is necessary for resolution of acute inflammation. Failure of this neural circuit could promote procarcinogenic inflammation and altered tumour immunity. Here we show that splenic TFF2, a secreted anti-inflammatory peptide, is released by vagally modulated memory T cells to suppress the expansion of MDSCs through CXCR4. Splenic denervation interrupts the anti-inflammatory neural arc, resulting in the expansion of MDSCs and colorectal cancer. Deletion of Tff2 recapitulates splenic denervation to promote carcinogenesis. Colorectal carcinogenesis could be suppressed through transgenic overexpression of TFF2, adenoviral transfer of TFF2 or transplantation of TFF2-expressing bone marrow. TFF2 is important to the anti-inflammatory reflex arc and plays an essential role in arresting MDSC proliferation. TFF2 offers a potential approach to prevent and to treat cancer. PMID:26841680

Arterial embolization, therapeutic delay, enphrectomy, and medroxyprogesterone yield a response rate of 28% in patients with renal cell carcinoma and pulmonary parenchymal metastases. (2) Liver. The carcinoid syndrome secondary to hepatic metastases can be controlled by embolization in 87% of patients. Islet cell carcinoma of the pancreas with hepatic metastases is successfully managed in 75% of patients. Chemoembolization (Ivalon and cisplatin) has been effective in 60% of patients with hepatic metastases from ocular melanoma. (3) Bone. A 73% 3-year survival rate is now possible with the inraarterial infusion of cisplatin, while Adriamycin is given intravenously in patients with osteosarcoma. Limb salvage is now possible in 80% of cases. Cancers of the vulva, vagina, urethra, and penis have been successfully treated with intraarterial infusion of chemotherapy followed by radiation therapy. (5) An expansile metallic stent is available to alleviate obstructions of the vena cava, the aorta and its major branches, the tracheobronchial tree, and the common duct.

    Chemotherapy-related cognitive impairment (CRCI) can occur during or after chemotherapy and represents a concern for many patients with cancer. Among older patients with cancer, in whom there is little clinical trial evidence examining side effects like CRCI, many unanswered questions remain regarding risk for and resulting adverse outcomes from CRCI. Given the rising incidence of cancer with age, CRCI is of particular concern for older patients with cancer who receive treatment. Therefore, research related to CRCI in older patients with cancers is a high priority. In this manuscript, we discuss current gaps in research highlighting the lack of clinical studies of CRCI in older adults, the complex mechanisms of CRCI, and the challenges in measuring cognitive impairment in older patients with cancer. Although we focus on CRCI, we also discuss cognitive impairment related to cancer itself and other treatment modalities. We highlight several research priorities to improve the study of CRCI in older patients with cancer. PMID:27197918

    Thrombosis and thromboembolic events contribute to significant morbidity in cancer patients. Venous thrombosis embolism (which includes deep vein thrombosis and pulmonary embolism) accounts for a large percentage of thromboembolic events. Appropriate identification of cancer patients at high risk for venous thromboembolism and management of thromboembolic event is crucial in improving the quality of care for cancer patients. However, thromboembolism in cancer patients is a complex problem and the management has to be tailored to each individual. The focus of this review is to understand the complex pathology, physiology and risk factors that drive the process of venous thrombosis and embolism in cancer patients and the current guidelines in management.

  4. Every second cancer patient receives radiotherapy

    International Nuclear Information System (INIS)

    Radiotherapy to treat cancer was given for the first time exactly one hundred years ago. Today, radiotherapy and surgery are the two main modes of treating cancer. One in two cancer patients receives radiotherapy at some point during the course of treatment for the disease. Radiotherapy is applied most commonly in cases where surgery is not possible. Moreover, these two modes of treatment are often used together to supplement each other. About half of new cancer cases detected today can be ordered. The estimate given by the EU for cancers cured is 45 per cent, which is divided between the various treatment modes as follows: surgery 22 %, radiotherapy 12 %, surgery plus radiotherapy 6 %, and drug therapy 6 %. In addition to curative treatment, radiotherapy plays a crucial role in palliative treatment, i.e. treatment that alleviates symptoms. The sensitivity of malignant tumours to radiotherapy varies over a wide range; the same is true for healthy tissues. Radiotherapy can only be used to cure a tumour that is more sensitive to radiation than the surrounding healthy tissue. The tumour must also be sufficiently small in size and limited to a relatively small area. (orig.)

Aim of the present study is to identify serological biomarkers and early myopathic features in skeletal muscle biopsies from weight stable patients bearing colorectal cancer at the onset of disease. Morphometric analyses by histochemistry and immunohistochemistry were performed on intraoperative muscle biopsies from patients with early colorectal cancer and from weight stable patients undergoing surgery for benign non-inflammatory conditions. Serological analyses for testing markers of inflammation (C Reactive Protein, CRP, muscle enzymes, (Creatin Kinase, CK, soluble isoforms of adhesion molecules (Neural Cell Adhesion Molecule, NCAM, and a marker of protein turnover (prealbumin, a typical indicator of caloric and protein malnutrition were also performed. Fifty oncologic patients (28 male/22 female and 25 non oncologic patients (18 male/7 female (p=N.S. were studied. In muscles from cancer patients we observed a subclinical myopathy characterized by an abnormal distribution of myonuclei. The percentage of myofibers with internalized nuclei was significantly higher in oncologic (median= 13.1%, IQR= 6.0-20.3 than in non oncologic patients (median= 3%, IQR= 2.5-6.1 (p<0.0001. The frequency of these internally nucleated myofibers is even higher in a subgroup of oncologic patients taking myotoxic drugs. In cancer patients, we observed an inverse correlation between the number of internally nucleated fibers and the presence of node metastasis (N+ (ρ=-0.30 (p=0.03. Moreover, in patients with colorectal cancer, low serum levels of preoperative prealbumin (median= 167,7 mg/L, normal range 200-400 mg/L, were detected. The link between the observed early myopathy and long-term cachexia is supported also by the altered expression of sarcolemma associated proteins, in particular laminin and dystrophin

    The development of a recommendation was intended for the follow-up of breast cancer patients treated with curative intent in Hungary. Follow-up includes the permanent contact with and health education of the patient, the surveillance and control of the adverse effects of oncological therapies or radiotherapy, the screening of metachron cancers, and the comprehensive (physical, psychological and social) rehabilitation of the patient. The early detection of local/regional tumor relapse is essential with careful follow-up, but there is no need for screening of distant metastases by means of imaging studies or tumor marker tests. If adjuvant endocrine therapy is needed, optimal adherence should be ensured with supportive therapy. In rare cases, special issues such as breast cancer risk/genetic mutation, pregnancy are raised, which should be thoughtfully discussed in view of recent advances in oncology. Follow-up is generally practised by the oncologist, however, in some cases the social worker, the physiotherapist, the psychooncologist, or in special cases, the lymphoedema expert is to be involved. The follow-up approach should be comprehensive and holistic. PMID:27579724

    Introduction Clinical deterioration (ICU transfer and cardiac arrest) occurs during approximately 5–10% of hospital admissions. Existing prediction models have a high false positive rate, leading to multiple false alarms and alarm fatigue. We used routine vital signs and laboratory values obtained from the electronic medical record (EMR) along with a machine learning algorithm called a neural network to develop a prediction model that would increase the predictive accuracy and decrease false alarm rates. Design Retrospective cohort study. Setting The hematologic malignancy unit in an academic medical center in the United States. Patient Population Adult patients admitted to the hematologic malignancy unit from 2009 to 2010. Intervention None. Measurements and Main Results Vital signs and laboratory values were obtained from the electronic medical record system and then used as predictors (features). A neural network was used to build a model to predict clinical deterioration events (ICU transfer and cardiac arrest). The performance of the neural network model was compared to the VitalPac Early Warning Score (ViEWS). Five hundred sixty five consecutive total admissions were available with 43 admissions resulting in clinical deterioration. Using simulation, the neural network outperformed the ViEWS model with a positive predictive value of 82% compared to 24%, respectively. Conclusion We developed and tested a neural network-based prediction model for clinical deterioration in patients hospitalized in the hematologic malignancy unit. Our neural network model outperformed an existing model, substantially increasing the positive predictive value, allowing the clinician to be confident in the alarm raised. This system can be readily implemented in a real-time fashion in existing EMR systems. PMID:27532679

    Life expectancy for patients with breast carcinoma has changed in Europe over the last two decades. In Italy, the overall survival rate is about 77% at 5 years. When considering the situation in Sicily, the EUROCARE 2 study examined survival data from the Ragusa Cancer Registry, showing that the curves are worse than in other regions of Italy. Starting from these considerations we decide to evaluate whether these data from the Ragusa Cancer Registry corresponded to Palermo data. So we analysed data from 575 consecutive patients with breast cancer, treated in our Breast Unit from 1990 to 2003 according to the St. Gallen Recommendations and followed for a median period of 5 years. The prognostic role of age, tumour size, nodal status, TNM, stage, grading and hormonal receptors (OR, PR) were analysed and survival curves at 5 and 10 years were produced using the actuarial survival methods. All causes of death were considered. The median follow-up was 33 months. The Log rank test and univariate cox proportional model were used to demonstrate the association between prognostic factors and outcome. When considering T and N status, the curves showed an inverse correlation between survival and increases in these parameters. Overall survival was 92.9% at 5 years and 81.4% at 10 years for T1, 78.4% at 5 years and 61.4% at 10 years for T2 and 40.8% for T3-T4 at 5 and 10 years. Overall survival for NO was 92.1% and 78.2%, respectively, at 5 and 10 years, but decreased to 72.0% and 59.9% at 5 and 10 years for N1. In N2 patients we found that only about 50% of patients were still alive at 5 and 10 years, while for N3 patients the figures were 57.2% and 40%, respectively. PMID:17663369

    Objective To examine self-reported symptoms by the patients receiving cancer therapy, and find out the symptoms that should be coped with and managed during the treatment. Methods A pilot study was conducted on self-reported symptoms on 185 patients receiving chemotherapy and/or radiotherapy for different cancers. The Therapy-Related Symptoms Checklist (TRSC) was used. Results Severe symptoms on the TRSC subscales: loss of appetite,feeling sluggish, weight loss, nausea and hair loss, were reported by the patients. The frequently reported symptoms by those on chemotherapy were nausea, feeling sluggish, weight loss, vomiting, and taste change. The frequently reported symptoms by those on radiotherapy were feeling sluggish, weight loss, loss of appetite, difficult sleeping, and changing taste. The symptoms of loss of appetite, feeling sluggish, weight loss, hair loss, and nausea were both frequently reported by those on radiotherapy and those on chemotherapy. Conclusion Symptom monitoring may be facilitated by TRSC, based on the severity and frequency of reported symptoms, more patients and caregivers could know which symptoms should be preferential interventions.

    International Nuclear Information System (INIS)

    Objective: Based on T. N. M classification, this study was conducted to evaluate the clinical presentation of carcinoma of breast in central part of rural Sindh. Design: This is a 5-year combined study i.e. 3 years retrospective and 2 years prospective. Place and Duration of Study: This study was carried out at People's Medical College Hospital (PMCH) Nawabshah from June 1995 to May, 2000 for a period of five years. Subjects and Methods: Fifty patients having carcinoma breast and admitted to surgical department ware included in study. Results: Eighty four percent of these patients presented in advanced stage of the disease. Well established predisposing factors like early menarche, age at first pregnancy, breast feeding and number of children did not contribute to the risk of developing breast cancer in our patients. Conclusion: Majority of breast cancer patients present in advance stage of the disease, hence can not be benefited from modern methods of treatment. The reasons for this delayed presentation are multi fold and are discussed here. (author)

    Full Text Available Abstract Background Most of the studies about invasive Candida infections in cancer patients have focused on haematological patients. The aim of this study was to provide information about risk factors for candidaemia in patients with solid tumours. Methods Retrospective cohort study. During a 9-year period (1995–2003 we reviewed all cases of candidaemia that affected cancer patients in Santa Casa Complexo Hospitalar, Brazil. Results During the period of study, 210 patients had the diagnosis of candidaemia in our medical centre, and 83 of these patients had cancer (39.5%. The majority of patients with cancer had solid tumours (77.1%, mostly in the alimentary tract. Most of solid cancers were non-metastatic (71.9%. Major diagnoses in patients with haematological neoplasia were acute leukaemia (n = 13, high grade non-Hodgkin lymphoma (n = 5 and Hodgkin's disease (n = 1. Non-Candida albicans species caused 57.8% of the episodes of candidaemia in patients with cancer, mainly in patients with haematological malignancies (p = 0.034. Neutropenia and treatment with corticosteroids were more frequent in the haematological group, in comparison with patients with solid tumours. Only 22.2% of patients with solid tumours were neutropenic before candidaemia. Nonetheless, the presence of ileus and the use of anaerobicides were independent risk factors for candidaemia in patients with solid cancers. The overall mortality in cancer patients with candidaemia was 49.4%. We then compared 2 groups of adult patients with candidaemia. The first was composed of non-neutropenic patients with solid tumours, and the second group included patients without cancer. We found that central venous catheters and gastrointestinal surgery were independently associated with candidaemia in patients with solid tumour. Conclusion Cancer patients with candidaemia seem to have very different predisposing factors to acquire the infection when stratified according to baseline diseases

  5. Irradiation lung injury in lung cancer patients

    International Nuclear Information System (INIS)

    The effect of chest irradiation on pulmonary function was studied in 16 patients with lung cancer and one with malignant thymoma. Radiation pneumonitis was detected by chest radiography in 15 cases (88%), 35 days (average) after the completion of radiation therapy. In these cases the radiation field included the lungs, and the hilar and mediastinal regions. No radiation pneumonitis occurred in the other two patients, receiving only lung field irradiation. Various pulmonary functions were measured in all patients following radiation therapy. Inspiratory reserve volume, inspiratory capacity and diffusing capacity were significantly reduced 1 month and 3 months after the completion of radiotherapy. Furthermore, reduction of vital capacity was found 3 months after treatment. It may be concluded that pulmonary function tests are not useful in predicting the onset of radiation pneumonitis, as chest radiography revealed inflammatory changes before the reduction of pulmonary function was detected.

    There has been a concern that major bleeding events (MBE) on direct-acting oral anticoagulants (DOACs) will be more difficult to manage than on vitamin K antagonists. Patients with cancer and DOAC-associated bleeding may be even more of a challenge to manage. We therefore reviewed the literature on bleeding in patients with cancer on DOACs. In addition, we performed an analysis of individual patient data from 5 phase III trials on treatment with dabigatran with focus on those with cancer. In 6 randomized trials the risk of MBE in patients with cancer was similar on treatment with DOACs compared to vitamin K antagonists. Bleeding was in the majority of patients managed with supportive therapy alone. In the individual patient data analysis there were no significant differences in use of hemostatic products, transfusion of red cells, effectiveness of management, bleeding-related mortality or 30-day all-cause mortality between patients with cancer treated with dabigatran or with warfarin. Local hemostatic therapy, including resection of the cancer site was more common in patients with gastrointestinal bleeding with cancer than among those without cancer. We conclude that management of bleeding in patients with cancer and on a DOAC does not pose a greater challenge than management of bleeding in patients without cancer. PMID:27067968

    2014-05-01

    Cancer risk at low doses of ionizing radiation remains poorly defined because of ambiguity in the quantitative link to doses below 0.2 Sv in atomic bomb survivors in Hiroshima and Nagasaki arising from limitations in the statistical power and information available on overall radiation dose. To deal with these difficulties, a novel nonparametric statistics based on the 'integrate-and-fire' algorithm of artificial neural networks was developed and tested in cancer databases established by the Radiation Effects Research Foundation. The analysis revealed unique features at low doses that could not be accounted for by nominal exposure dose, including (i) the presence of a threshold that varied with organ, gender and age at exposure, and (ii) a small but significant bumping increase in cancer risk at low doses in Nagasaki that probably reflects internal exposure to (239)Pu. The threshold was distinct from the canonical definition of zero effect in that it was manifested as negative excess relative risk, or suppression of background cancer rates. Such a unique tissue response at low doses of radiation exposure has been implicated in the context of the molecular basis of radiation-environment interplay in favor of recently emerging experimental evidence on DNA double-strand break repair pathway choice and its epigenetic memory by histone marking.

    Full Text Available Objective: Resistance of metastatic lymph nodes (LNs to high dose I-131 therapy is associated with high morbidity in patients with differentiated thyroid cancer. We evaluated the role of F-18 FDG PET/CT in the prediction of resistance to high dose I-131 therapy in patients with papillary thyroid cancer. Methods: The subjects were 307 patients who underwent total or near total thyroidectomy followed by high dose (5.55-6.66 GBq I-131 therapy. We divided the patients into three subgroups by visual assessment of regional LNs: FDG-avid LNs with a malignant shape on CT (PET/CT-positive group, FDG-avid LNs with a benign shape on CT (PET/CT-intermediate group and no FDG-avid lesion (PET/CT-negative group. We measured the maximum SUV (SUVmax of FDG-avid LNs in each patient. The presence or absence of focal increased uptake of I-131 was evaluated by whole body scan (WBS, and was denoted as WBS-positive group or WBS-negative group, respectively. Resistance to therapy was defined as presence of thyroglobulin (Tg in serum (Tg ≥1.0 ng/ml 3-6 months after I-131 therapy. Univariate and multivariate analyses were performed to determine the relationship between resistance to I-131 therapy and various clinico-pathologic variables. Results: PET/CT-positive, intermediate, and negative groups included 20 (6.5%, 44 (14.3% and 243 (79.2% patients, respectively. The mean SUVmax was significantly higher in the PET/CT-positive group than that of the PET/CT-intermediate group (4.6 vs. 2.7, P

    The fight against cancer comprises not only survival of the disease but also survival with the highest possible quality of life. Thus, supportive care in cancer aims at reducing physical and psycho-emotional symptom burden. Furthermore, supportive care in cancer includes self-management-support for patients and their families/caregivers. Due to high symptom prevalence and poor prognosis, lung cancer patients express more unmet supportive care needs than other patient populations with cancer. Interventions to meet these needs have been developed in the last decade. They involve new models of care that incorporate the role of a lung cancer nurse in comprehensive cancer centers and eHealth-systems to support lung cancer patients and their families/caregivers.

  14. Radioimmunodetection in patients with suspected ovarian cancer

    International Nuclear Information System (INIS)

    Twenty-five patients, having either unilateral ovarian tumors of unknown etiology or suspected of having ovarian cancer recurrence were investigated by the method of immunoscintigraphy to rule out primary and/or metastatic tumor sites. Four-hundred micrograms of the tumor-associated monoclonal mouse antibody HMFG-2, raised against human milk fat globulin membranes and labeled with 123I, were used for each patient to display the tumor sites by external scintigraphy. The dose ranged between 0.5 and 2.2 mCi, the specific activity between 1.25 and 5.5 mCi per mg of antibody. Nineteen of the patients underwent operations a few days after immunoscintigraphy. The remaining six patients were investigated by transmission computed tomography (TCT) to establish the presence or absence of tumor of the imaging. In 22 of the 25 cases the scintigraphic results correlated with the situation found at the subsequent operation, or by TCT, respectively, as well as with the histological diagnosis of the tumor type. Overall, there were just two false-negative and one false-positive scan report, the latter due to faulty reading of the scintigrams. Sixteen out of 18 tumor sites in 25 patients could be revealed by immunoscintigraphy, the smallest one being 1.5 cm in diam. In four of the patients immunoscintigraphy was the only noninvasive investigation method that could reveal the malignant tumor sites prior to the operation

    Shames, H; Raz, N; Levin, Netta

    2015-07-01

    Posterior cortical atrophy (PCA) is a neurodegenerative syndrome in which the most pronounced pathologic involvement is in the occipito-parietal visual regions. Herein, we aimed to better define the cortical reflection of this unique syndrome using a thorough battery of behavioral and functional MRI (fMRI) tests. Eight PCA patients underwent extensive testing to map their visual deficits. Assessments included visual functions associated with lower and higher components of the cortical hierarchy, as well as dorsal- and ventral-related cortical functions. fMRI was performed on five patients to examine the neuronal substrate of their visual functions. The PCA patient cohort exhibited stereopsis, saccadic eye movements and higher dorsal stream-related functional impairments, including simultant perception, image orientation, figure-from-ground segregation, closure and spatial orientation. In accordance with the behavioral findings, fMRI revealed intact activation in the ventral visual regions of face and object perception while more dorsal aspects of perception, including motion and gestalt perception, revealed impaired patterns of activity. In most of the patients, there was a lack of activity in the word form area, which is known to be linked to reading disorders. Finally, there was evidence of reduced cortical representation of the peripheral visual field, corresponding to the behaviorally assessed peripheral visual deficit. The findings are discussed in the context of networks extending from parietal regions, which mediate navigationally related processing, visually guided actions, eye movement control and working memory, suggesting that damage to these networks might explain the wide range of deficits in PCA patients.

    Full Text Available Lung cancer (LC annually afflicts 63–65 thousand people in Russia and 1.04 million worldwide, which amounts to 12.8% of all notified cases of neoplasms. In LC patients, infectious complications are characterized by a severe course; destruction foci, decay cavities, and abscess may form.All give rise to difficulties in making a diagnosis and in choosing a treatment policy. Infections caused by P. aeruginosa, A. baumanii, bacteria of the family Enterobacteriacae, S. aureus, and Enterococcus spp present the greatest problem in inpatients with LC. The early diagnosis of infectiouscomplications and the use of adequate schemes of antibiotic prevention and therapy promote a reduction in mortality from infection in this categoryof patients and expand the possibilities of their specific antitumor treatment.

    Having a relationship with one's parents is a fundamental social interaction and is a significant environmental factor in the long-term course of illness in schizophrenia. We explored subjective reports regarding the communicative relationship with parents and the implicit behavioral and neural responses of patients toward stimuli that referred to parents. Fourteen outpatients with schizophrenia and 15 healthy volunteers with living parents were scanned using a functional magnetic resonance imaging while performing an imaginary sentence completion test that involved contemplation of their mothers and fathers. In patients with schizophrenia, subjective reports of better communicative fluency with one's mother were associated with faster response time and lower incomplete rate, reflecting favorable responses toward mothers. Relative to control participants, patients with schizophrenia demonstrated greater neural activation in the superior temporal sulcus and the parahippocampal gyrus for parental stimuli. When patients with schizophrenia contemplated their mothers, activities in these regions were associated with a level of negative symptoms or affective ambivalence in patients. The results indicated that parental cues are processed in a more socially driven manner, and that perceived communicative relationships with one's parents can be used to estimate implicit responses, especially in relation to mothers in patients with schizophrenia. Furthermore, the findings of the current study suggest that affective ambivalence toward one's mother is one such implicit response and emphasize the importance of prudent family interventions in the psychiatric rehabilitation of patients with schizophrenia.

    Full Text Available Problem statement: The presence of metastasis in the regional lymph nodes is the most important factor in predicting prognosis in breast cancer. Many biomarkers have been identified that appear to relate to the aggressive behaviour of cancer. However, the nonlinear relation of these markers to nodal status and also the existence of complex interaction between markers have prohibited an accurate prognosis. Approach: The aim of this study is to investigate the effectiveness of a Multilayer Perceptron (MLP for predicting breast cancer progression using a set of four biomarkers of breast tumors. The biomarkers include DNA ploidy, cell cycle distribution (G0G1/G2M, steroid receptors (ER/PR and S-Phase Fraction (SPF. A further objective of the study is to explore the predictive potential of these markers in defining the state of nodal involvement in breast cancer. Two methods of outcome evaluation viz. stratified and simple k-fold Cross Validation (CV are studied in order to assess their accuracy and reliability for neural network validation. Criteria such as output accuracy, sensitivity and specificity are used for selecting the best validation technique besides evaluating the network outcome for different combinations of markers. Results: The results show that stratified 2-fold CV is more accurate and reliable compared to simple k-fold CV as it obtains a higher accuracy and specificity and also provides a more stable network validation in terms of sensitivity. Best prediction results are obtained by using an individual marker-SPF which obtains an accuracy of 65%. Conclusion/Recommendations: Our findings suggest that MLP-based analysis provides an accurate and reliable platform for breast cancer prediction given that an appropriate design and validation method is employed.

    Full Text Available Objective: In a regional hospital, many patients are newly diagnosed with cancer. Breaking the bad news in these patients and their relatives is a tough task. Many doctors are not experienced in talking to patients about death or death-related diseases. In recent years, there have been great efforts to change the current situation. The aim of this study was to investigate the experience and education of medical personnel in breaking bad news in a secondary hospital. Materials and Methods: 59 doctors from General Hospital of Komotini, Greece were included in the study. All the doctors were in clinical specialties that treated cancer patients. A brief questionnaire was developed based on current guidelines such as Baile/SPIKES framework and the ABCDE mnemonic. Results: Residents are involved in delivering bad news less frequently than specialists. Only 21 doctors (35.59% had specific training on breaking bad news. 20 doctors (33.90% were aware of the available techniques and protocols on breaking bad news. 47 doctors (79.66% had a consistent plan for breaking bad news. 57 (96.61% delivered bad news in a quiet place, 53 (89.83% ensured no interruptions and enough time, 53 (89.83% used simple words and 54 (91.53% checked for understanding and did not rush through the news. 46 doctors (77.97% allowed relatives to determine patient′s knowledge about the disease. Conclusions: There were low rates of specific training in breaking bad news. However, the selected location, the physician′s speech and their plan were according to current guidelines.

    The goal of the present research is to investigate and analyze possible peculiarities of the psychological state of cancer patients undergoing treatment. Scores characterizing the trait and state anxiety were acquired using the Integrative Anxiety Test from four groups: adults with no appreciable disease, pregnant women, cancer patients examined during the specific antitumor treatment, and cancer patients brought into lasting clinical remission. Statistical analysis of the testing results revealed the bimodal type of the distribution of scores. The only statistically significant exception was the distribution of the state anxiety scores in cancer patients undergoing treatment that was clearly unimodal. PMID:26176239

    Full Text Available PURPOSE: Report the characteristics of cryopreserved semen from a cohort of male cancer patients, attitudes towards cryopreservation and outcomes of semen samples based on a 12-year cryopreservation program. MATERIAL AND METHODS: Data from 98 male cancer patients whose sperm samples were banked were evaluated. Demographic parameters, semen characteristics, destination of sperm banked samples and questionnaires answered by the patients regarding cryopreservation time were evaluated. RESULTS: The cancer diagnoses were testicle (56.1%, prostate (15.3%, Hodgkin’s lymphomas (9.2%, non-Hodgkin’s lymphomas (7.1%, leukemia (3.1% and other malignancies (9.2%. The patients with testicular cancer presented lower sperm concentration (p < 0.001; however, there were no differences with the percentage of normozoospermic patients among cancer type groups (p = 0.185. A shorter time between cancer diagnosis and sperm banking was observed for testicular and prostate cancer patients (p < 0.001. Most of the patients (89.5% favored sperm banking as a fertility preservation method. CONCLUSIONS: Although less than 20% of banked sperm samples were disposed of, the majority of patients related sperm banking with safe for fertility preservation. Our results show that all male cancer patients of reproductive age facing cancer treatment could be offered sperm banking.

    Full Text Available Neurotransmitters are identified to be endogenous chemicals and act on neurons to transmit signals to each other or to a target cell across synapse. They are involved in many brain functions including analgesia, reward, food intake, metabolism, reproduction, social behaviors, learning, and memory. Recently, sympathetic nerve fibers were detected in many solid tumors including gastrointestinal cancer, supporting the idea that neural system has effects on tumor progression. Neurotransmitters were secreted from the sympathetic nerve fibers and subsequently infiltrated into tumor tissues. Further studies disclosed the different mechanisms of various kinds of neurotransmitters in the progression of carcinogenesis, including tumor cell proliferation, angiogenesis, and tumor invasion and metastasis. Neurotransmitters are mainly subdivided into four types, amino acids, monoamines, peptides, and others, each of which contains multiple chemicals. For this reason, we cannot describe each in detail. In this review, we will focus on several important neurotransmitters including tachykinis, neuropeptide Y, and b-adrenergic receptors. How they function and their crosstalks with the immune system in the progression, especially the metastasis of gastrointestinal cancer, will be described. Finally, we will summarize the clinical implications in the treatment of gastrointestinal cancer.

    The purpose of this review is to analyse current options for fertility preservation in young women with breast cancer (BC). Considering an increasing number of BC survivors, owing to improvements in cancer treatment and delaying of childbearing, fertility preservation appears to be an important issue. Current fertility preservation options in BC survivors range from well-established standard techniques to experimental or investigational interventions. Among the standard options, random-start ovarian stimulation protocol represents a new technique, which significantly decreases the total time of the in vitro fertilisation cycle. However, in patients with oestrogen-sensitive tumours, stimulation protocols using aromatase inhibitors are currently preferred over tamoxifen regimens. Cryopreservation of embryos and oocytes are nowadays deemed the most successful techniques for fertility preservation in BC patients. GnRH agonists during chemotherapy represent an experimental method for fertility preservation due to conflicting long-term outcome results regarding its safety and efficacy. Cryopreservation of ovarian tissue, in vitro maturation of immature oocytes and other strategies are considered experimental and should only be offered within the context of a clinical trial. An early pretreatment referral to reproductive endocrinologists and oncologists should be suggested to young BC women at risk of infertility, concerning the risks and benefits of fertility preservation options.

    The prediction of cancer staging in prostate cancer is a process for estimating the likelihood that the cancer has spread before treatment is given to the patient. Although important for determining the most suitable treatment and optimal management strategy for patients, staging continues to present significant challenges to clinicians. Clinical test results such as the pre-treatment Prostate-Specific Antigen (PSA) level, the biopsy most common tumor pattern (Primary Gleason pattern) and the second most common tumor pattern (Secondary Gleason pattern) in tissue biopsies, and the clinical T stage can be used by clinicians to predict the pathological stage of cancer. However, not every patient will return abnormal results in all tests. This significantly influences the capacity to effectively predict the stage of prostate cancer. Herein we have developed a neuro-fuzzy computational intelligence model for classifying and predicting the likelihood of a patient having Organ-Confined Disease (OCD) or Extra-Prostatic Disease (ED) using a prostate cancer patient dataset obtained from The Cancer Genome Atlas (TCGA) Research Network. The system input consisted of the following variables: Primary and Secondary Gleason biopsy patterns, PSA levels, age at diagnosis, and clinical T stage. The performance of the neuro-fuzzy system was compared to other computational intelligence based approaches, namely the Artificial Neural Network, Fuzzy C-Means, Support Vector Machine, the Naive Bayes classifiers, and also the AJCC pTNM Staging Nomogram which is commonly used by clinicians. A comparison of the optimal Receiver Operating Characteristic (ROC) points that were identified using these approaches, revealed that the neuro-fuzzy system, at its optimal point, returns the largest Area Under the ROC Curve (AUC), with a low number of false positives (FPR = 0.274, TPR = 0.789, AUC = 0.812). The proposed approach is also an improvement over the AJCC pTNM Staging Nomogram (FPR = 0.032, TPR

  19. VMAT planning study in rectal cancer patients

    International Nuclear Information System (INIS)

    To compare the dosimetric differences among fixed field intensity-modulated radiation therapy (IMRT), single-arc volumetric-modulated arc therapy (SA-VMAT) and double-arc volumetric-modulated arc therapy (DA-VMAT) plans in rectal cancer. Fifteen patients with rectal cancer previously treated with IMRT in our institution were selected for this study. For each patient, three plans were generated with the planning CT scan: one using a fixed beam IMRT, and two plans using the VMAT technique: SA-VMAT and DA-VMAT. Dose prescription to the PTV was 50 Gy in 2 Gy per fraction. Dose volume histograms (DVH) for the target volume and the organs at risk (small bowel, bladder, femoral heads and healthy tissue) were compared for these different techniques. Monitor units (MU) and delivery treatment time were also reported. DA-VMAT achieved the highest minimum planning target volume (PTV) dose and the lowest maximal dose, resulting in the most homogeneous PTV dose distribution. DA-VMAT also yielded the best CI, although the difference was not statistically significant. Between SA-VMAT and IMRT, the target dose coverage was largely comparable; however, SA-VMAT was able to achieve a better V95 and V107. VMAT showed to be inferior to IMRT in terms of organ at risk sparing, especially for the small bowel. Compared with IMRT, DA-VMAT increased the V15 of small bowel nearly 55 cc. The MU and treatment delivery time were significantly reduced by the use of VMAT techniques. VMAT is a new radiation technique that combines the ability to achieve highly conformal dose distributions with highly efficient treatment delivery. Considering the inferior role of normal tissue sparing, especially for small bowel, VMAT need further investigation in rectal cancer treatment

    International Nuclear Information System (INIS)

    Background and purpose: Elderly patients with head and neck cancer may not be treated aggressively with radiotherapy, due to concerns regarding tolerance of treatment and toxicity. A retrospective study was undertaken of patients aged 80 years and over, treated by definitive radiotherapy for head and neck cancer. Material and methods: 98 patients aged 80-92 received radiotherapy for carcinoma of the head and neck between 1991 and 1995. All patients received beam directed radiotherapy with radical intent using an immobilisation shell. Results: Cancer specific survival was 59% and overall local control was 70% at 5 years. Both were significantly affected by T stage and site of disease. Cancer specific survival was comparable to that of patients aged below 80 years. Seven patients died within 6 months of the treatment. Three patients developed severe late toxicity. Metastatic disease occurred in eight patients. Conclusions: Radiotherapy is a beneficial and well tolerated treatment in elderly patients with carcinoma of the head and neck

  3. Infrared-Guided Patient Setup for Lung Cancer Patients

    International Nuclear Information System (INIS)

    Purpose: To evaluate the utility of an infrared-guided patient setup (iGPS) system to reduce the uncertainties in the setup of lung cancer patients. Methods and Materials: A total of 15 patients were setup for lung irradiation using skin tattoos and lateral leveling marks. Daily electronic portal device images and iGPS marker locations were acquired and retrospectively reviewed. The iGPS-based shifts were compared with the daily electronic portal device image shifts using both the central axis iGPS marker and all five iGPS markers. For shift calculation using the five markers, rotational misalignment was included. The level of agreement between the iGPS and portal imaging to evaluate the setup was evaluated as the frequency of the shift difference in the range of 0-5 mm, 5-10 mm, and >10 mm. Results: Data were obtained for 450 treatment sessions for 15 patients. The difference in the isocenter shifts between the weekly vs. daily images was 0-5 mm in 42%, 5-10 mm in 30%, and >10 mm in 10% of the images. The shifts seen using the iGPS data were 0-5 mm in 81%, 5-10 mm in 14%, and >10 mm in 5%. Using only the central axis iGPS marker, the difference between the iGPS and portal images was 10 mm in 7% in the left-right direction and 73%, 18%, and 9% in the superoinferior direction, respectively. When all five iGPS markers were used, the disagreements between the iGPS and portal image shifts >10 mm were reduced from 7% to 2% in the left-right direction and 9% to 3% in the superoinferior direction. Larger reductions were also seen (e.g., a reduction from 50% to 0% in 1 patient). Conclusion: The daily iGPS-based shifts correlated well with the daily electronic portal device-based shifts. When patient movement has nonlinear rotational components, a combination of surface markers and portal images might be particularly beneficial to improve the setup for lung cancer patients

    Full Text Available Background. We study the clinical significance and management of pulmonary venous obstruction in cancer patients. Methods. We conducted a prospective cohort study to characterize the syndrome that we term “pulmonary vein obstruction syndrome” (PVOS between January 2005 and March 2014. The criteria for inclusion were (1 episodes of shortness of breath; (2 chest X-ray showing abnormal pulmonary hilum shadow with or without presence of pulmonary edema and/or pleural effusion; (3 CT scan demonstrating pulmonary vein thrombosis/tumor with or without tumor around the vein. Results. Two hundred and twenty-two patients developed PVOS. Shortness of breath was the main symptom, which was aggravated by chemotherapy in 28 (13%, and medical/surgical procedures in 21 (9% and showed diurnal change in intensity in 32 (14%. Chest X-rays all revealed abnormal pulmonary hilum shadows and presence of pulmonary edema in 194 (87% and pleural effusion in 192 (86%. CT scans all showed pulmonary vein thrombosis/tumor (100% and surrounding the pulmonary veins by tumor lesions in 140 patients (63%. PVOS was treated with low molecular weight heparin in combination with dexamethasone, and 66% of patients got clinical/image improvement. Conclusion. Physicians should be alert to PVOS when shortness of breath occurs and chest X-ray reveals abnormal pulmonary hilum shadows.

    Objective: Knowledge, information and communication, within oncology, are a core clinical strength for the out-come of the disease and inadequate communication, can cause distress for the patient and their families. Design: A senior doctor conducted this study by filling in the performa after interviewing the subject of the study. Place and duration of study: This study was done in Oncology Department of Service Hospital, Lahore and was completed in four months. Subjects and Method: One hundred cancer patients were interviewed regarding their knowledge about their disease, its causes, prognosis, and information supplied by the health-care providers. They were also asked about their satisfaction regarding this information, deficiencies and pitfalls in this information, need for more information, which should supply the information from among the hospital team or their relative, attitude of the family and their communication regarding the disease. Results: Study revealed that the knowledge about the disease and its causes was present in 53% and 7% respectively. The patients (59%) wanted more information. Majority perceived that the information was not adequate and needed more information and 68% thought that more information would reduce their anxiety. The attitude of family was found encouraging in 87% of patients and 42% were communicating with other family members regarding their diseases. Conclusion: Knowledge about the disease and its cause should be increasingly supplied by the doctors, as it will reduce the anxiety and have a good effect on health. Communication among the family members needs to be improved. (author)

    Full Text Available BACKGROUND: We hypothesized that hidden malignancy could be detected in patients with cryptogenic stroke without active cancer when they showed the distinctive characteristics of cancer-related stroke. METHODS AND FINDINGS: Among 2,562 consecutive patients with acute ischemic stroke, patients with cryptogenic stroke were analyzed and categorized into two groups according to the presence of active cancer: cryptogenic stroke with active cancer (cancer-related stroke, CA-stroke group and without active cancer (CR-stroke group. Patients with active lung cancer without stroke were also recruited for comparison purposes (CA-control. Clinical factors, lesion patterns on diffusion-weighted MRI (DWI, and laboratory findings were analyzed among groups. A total of 348 patients with cryptogenic stroke were enrolled in this study. Among them, 71 (20.4% patients had active cancer at the time of stroke. The D-dimer levels were significantly higher in patients with CA-stroke than those with CR-stroke or CA-control (both p<0.001. Regarding lesion patterns, patients with CA-stroke mostly had multiple lesions in multiple vascular territories, while more than 80% of patients with CR-stroke had single/multiple lesions in a single vascular territory (P<0.001. D-dimer levels (OR 1.11 per 1 µg/mL increase; 95% CI 1.06-1.15; P<0.001 and DWI lesion patterns (OR 7.13; 95% CI 3.42-14.87; P<0.001 were independently associated with CA-stroke. Workup for hidden malignancy was performed during hospitalization in 10 patients who showed elevated D-dimer levels and multiple infarcts involving multiple vascular territories but had no known cancer, and it revealed hidden malignancies in all the patients. CONCLUSION: Patients with CA-stroke have distinctive D-dimer levels and lesion patterns. These characteristics can serve as clues to occult cancer in patients with cryptogenic stroke.

  10. Evaluation of QOL in cancer patients treated with radiation therapy

    International Nuclear Information System (INIS)

    Evaluation of quality of life (QOL) in cancer patients is an important theme. However, we do not have an established method to assess QOL in cancer patients during radiotherapy in Japan. We evaluated both the changes of QOL and the factors affecting QOL in radiotherapy patients. Three hundred fifty-five cancer patients, who filled in a questionnaire at the beginning, middle, and end of radiotherapy between 1998 and 2001, were studied. We used The QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs (QOL-ACD)'' devised by Kurihara et al, the Ministry of Health and Welfare. The QOL Questionnaire had five categories: physical activity, physical condition, mental state, social interaction, and face scale. The total score, sum of the score of five categories, were established synthetically (maximum score is 110). The mean of total QOL scores were 75.8, 77.6, and 78.2 at the beginning, middle, and end of radiotherapy respectively. Patients with symptoms related to cancer had apparent improvement of QOL score. Patients receiving chemotherapy had a decreased QOL score at the end of radiotherapy. The score of physical condition was reduced improvement. It was suggested that radiotherapy could be performed without losing QOL of cancer patients, including older patients. However, patients receiving chemotherapy and those with head and neck cancer may lose their QOL, therefore, we should treat such patients carefully. (author)

  16. Caring for cancer patients in the general dental office

    International Nuclear Information System (INIS)

    Modern therapeutic modalities and emphasis on early detection have made oral cancer a treatable, and in many cases, a curable disease. The role of the dentist in cancer patient management is two-fold. Early detection of oral lesions during routine dental examination has been shown to be a significant factor in cancer diagnosis. The dentist's other role comes after cancer treatment, specifically therapeutic radiation. Ionizing radiation can have permanent effects on both hard and soft tissues. Prescription and use of fluoride gel in topical applicators can aid in assuring oral health for post-cancer patients

    Science.gov (United States)

    The purpose of the study is to modify a type of counseling called "Individual Meaning Centered Psychotherapy" to meet the needs of Chinese cancer patients. Many cancer patients use counseling or other resources to help cope with the emotional burden of their illnesses. Counseling often helps them cope with cancer by giving them a place to express their feelings. "Meaning-Centered" counseling aims to teach cancer patients how to maintain or even increase a sense of meaning and purpose in their lives, despite cancer. |

    The CLECOS_P system was conceived for registering and automating the processing of clinical evaluations performed on patients with Parkinson's disease who undergo functional neurosurgery and/or neural transplant. CLECOS_P represents the first time a computerized system is able to offer--with high precision and considerable time-savings--an integral analysis of the evolutive behavior of the universe in integrated variables at the core assessment program for intracerebral transplantations (CAPIT). CAPIT is used internationally for the evaluation and follow-up of patients with this pathology who have undergone neural transplant. We used the so-called MEDSAC methodology for the preparation of this system. The methodology that was used for the design of an intelligent system aimed at medical decision-making was based on the quantitative analysis of the clinical evolution. At the present moment, there are 20 patients controlled by this system: 11 bilaterally transplanted, 9 unilaterally (registered in ranks of 3 months before operation up to 1, 2, 3, 6, 9, 12, 18, and 24 months after operation). The application of CLECOS_P to these patients permitted the evaluation of 400 clinical variables, where a better evolutive characterization of the patients was obtained, thus getting most favorable results with personalized therapeutic methods aimed at raising their quality of life. CLECOS_P is used in a multi-user environment on a local area network running Novell Netware version 3.11. PMID:8591284

  3. Pre-Operative Prediction of Advanced Prostatic Cancer Using Clinical Decision Support Systems: Accuracy Comparison between Support Vector Machine and Artificial Neural Network

    International Nuclear Information System (INIS)

    The purpose of the current study was to develop support vector machine (SVM) and artificial neural network (ANN) models for the pre-operative prediction of advanced prostate cancer by using the parameters acquired from transrectal ultrasound (TRUS)-guided prostate biopsies, and to compare the accuracies between the two models. Five hundred thirty-two consecutive patients who underwent prostate biopsies and prostatectomies for prostate cancer were divided into the training and test groups (n = 300 versus n 232). From the data in the training group, two clinical decision support systems (CDSSs-[SVM and ANN]) were constructed with input (age, prostate specific antigen level, digital rectal examination, and five biopsy parameters) and output data (the probability for advanced prostate cancer [> pT3a]). From the data of the test group, the accuracy of output data was evaluated. The areas under the receiver operating characteristic (ROC) curve (AUC) were calculated to summarize the overall performances, and a comparison of the ROC curves was performed (p < 0.05). The AUC of SVM and ANN is 0.805 and 0.719, respectively (p = 0.020), in the pre-operative prediction of advanced prostate cancer. Te performance of SVM is superior to ANN in the pre-operative prediction of advanced prostate cancer.

    Background: Erythroderma is an inflammation of the skin, which can be triggered by various diseases as psoriasis, allergies, side effects of medication, infections or malignant tumors. Caused by these various etiologic possibilities patients require extensive diagnostic effort. Patient: We report a case of a 71-year-old man presenting with an erythroderma of unknown etiology. Therapy with corticosteroids was not successful. A complete remission was reached by therapy with cyclosporine A, 350 mg/day. Finally, an increased prostate specific antigene (PSA) value was found and a prostate cancer was diagnosed in the patient. Results: After definitive radiotherapy of the carcinoma (total dose 74 Gy, 5 x 2 Gy/week), the cyclosporine A was displaced without recurrence of erythroderma. Conclusion: In this case, we consider the erythroderma to have been a paraneoplastic effect of the prostate carcinoma. In male patients with erythroderma an early PSA test should be performed. (orig.) [German] Hintergrund: Die Erythrodermie ist eine entzuendliche Reaktion der Haut, die durch verschiedene Grunderkrankungen wie Psoriasis, Allergien, Infektionen, Nebenwirkungen von Medikamenten oder paraneoplastisch in Erscheinung treten kann. Wegen dieser vielfachen aetiologischen Moeglichkeiten erfordern Erythrodermiepatienten eine aufwaendige Diagnostik. Patient: Wir berichten ueber einen 71-jaehrigen Patienten mit einer Erythrodermie zunaechst unbekannter Aetiologie. Durch die Gabe von Cyclosporin A in einer Dosis von 350 mg/Tag konnte eine Remission erreicht werden. Schliesslich wurde bei dem Patienten ein erhoehter Wert des prostataspezifischen Antigens (PSA) im Blut gefunden und daraufhin ein Prostatakarzinom diagnostiziert. Ergebnisse: Nach primaerer perkutaner Strahlentherapie des Prostatakarzinoms (Gesamtdosis 74 Gy, 5 x 2 Gy/Woche) konnte das Cyclosporin A abgesetzt werden, ohne dass ein weiterer Schub der Erythrodermie auftrat. Schlussfolgerung: Wir halten die Erythrodermie bei

    Tsang, Julian S

    2012-02-01

    BACKGROUND: Cancer patients have an increased risk of venous thromboembolic events. Certain chemotherapeutic agents have also been associated with the development of thrombosis. Reported cases of acute arterial ischemic episodes in cancer patients are rare. METHODS: Patients who underwent surgery for acute limb ischemia associated with malignancy in a university teaching hospital over a 10-year period were identified. Patient demographics, cancer type, chemotherapy use, site of thromboembolism, treatment and outcome were recorded. RESULTS: Four hundred nineteen patients underwent surgical intervention for acute arterial ischemia, 16 of these patients (3.8%) had associated cancer. Commonest cancer sites were the urogenital tract (n = 5) and the lungs (n = 5). Eight patients (50%) had been recently diagnosed with cancer, and four (25%) of these cancers were incidental findings after presentation with acute limb ischemia. Four patients (25%) developed acute ischemia during chemotherapy. The superficial femoral artery was the most frequent site of occlusion (50%), followed by the brachial (18%) and popliteal (12%) arteries. All patients underwent thromboembolectomy, but two (12%) patients subsequently required a bypass procedure. Six patients (37%) had limb loss, and in-patient mortality was 12%. Histology revealed that all occlusions were due to thromboembolism, with no tumor cells identified. At follow-up, 44% of patients were found to be alive after 1 year. CONCLUSION: Cancer and chemotherapy can predispose patients to acute arterial ischemia. Unlike other reports that view this finding as a preterminal event most appropriately treated by palliative measures, in this series, early diagnosis and surgical intervention enabled limb salvage and patient survival.

    Evidence shows that continued smoking by cancer patients leads to adverse treatment outcomes and affects survival. Smoking diminishes treatment effectiveness, exacerbates side effects, and increases the risk of developing additional complications. Patients who continue to smoke also have a higher risk of developing a second primary cancer or experiencing a cancer recurrence, both of which ultimately contribute to poorer quality of life and poorer survival.

    Full Text Available INTRODUCTION: This study aimed to evaluate the effect of the neural mobilization technique on electromyography function, disability degree, and pain in patients with leprosy. METHODS: A sample of 56 individuals with leprosy was randomized into an experimental group, composed of 29 individuals undergoing treatment with neural mobilization, and a control group of 27 individuals who underwent conventional treatment. In both groups, the lesions in the lower limbs were treated. In the treatment with neural mobilization, the procedure used was mobilization of the lumbosacral roots and sciatic nerve biased to the peroneal nerve that innervates the anterior tibial muscle, which was evaluated in the electromyography. RESULTS: Analysis of the electromyography function showed a significant increase (p<0.05 in the experimental group in both the right (Δ%=22.1, p=0.013 and the left anterior tibial muscles (Δ%=27.7, p=0.009, compared with the control group pre- and post-test. Analysis of the strength both in the movement of horizontal extension (Δ%right=11.7, p=0.003/Δ%left=27.4, p=0.002 and in the movement of back flexion (Δ%right=31.1; p=0.000/Δ%left=34.7, p=0.000 showed a significant increase (p<0.05 in both the right and the left segments when comparing the experimental group pre- and post-test. The experimental group showed a significant reduction (p=0.000 in pain perception and disability degree when the pre- and post-test were compared and when compared with the control group in the post-test. CONCLUSIONS: Leprosy patients undergoing the technique of neural mobilization had an improvement in electromyography function and muscle strength, reducing disability degree and pain.

    Colorectal cancer is emerging as one of the commonest cancers in Malaysia. Data on colorectal cancer from the National Cancer Registry is very limited. Comprehensive information on all aspects of colorectal cancer, including demographic details, pathology and treatment outcome are needed as the management of colorectal cancer has evolved rapidly over the years involving several disciplines including gastroenterology, surgery, radiology, pathology and oncology. This registry will be an important source of information that can help the development of guidelines to improve colorectal cancer care relevant to this country. The database will initially recruit all colorectal cancer cases from eight hospitals. The data will be stored on a customized web-based case report form. The database has begun collecting data from 1 October 2007 and will report on its first year findings at the end of 2008. PMID:19230248

    2016-01-01

    Open clinical trial data offer many opportunities for the scientific community to independently verify published results, evaluate new hypotheses and conduct meta-analyses. These data provide a springboard for scientific advances in precision medicine but the question arises as to how representative clinical trials data are of cancer patients overall. Here we present the integrative analysis of data from several cancer clinical trials and compare these to patient-level data from The Cancer Genome Atlas (TCGA). Comparison of cancer type-specific survival rates reveals that these are overall lower in trial subjects. This effect, at least to some extent, can be explained by the more advanced stages of cancer of trial subjects. This analysis also reveals that for stage IV cancer, colorectal cancer patients have a better chance of survival than breast cancer patients. On the other hand, for all other stages, breast cancer patients have better survival than colorectal cancer patients. Comparison of survival in different stages of disease between the two datasets reveals that subjects with stage IV cancer from the trials dataset have a lower chance of survival than matching stage IV subjects from TCGA. One likely explanation for this observation is that stage IV trial subjects have lower survival rates since their cancer is less likely to respond to treatment. To conclude, we present here a newly available clinical trials dataset which allowed for the integration of patient-level data from many cancer clinical trials. Our comprehensive analysis reveals that cancer-related clinical trials are not representative of general cancer patient populations, mostly due to their focus on the more advanced stages of the disease. These and other limitations of clinical trials data should, perhaps, be taken into consideration in medical research and in the field of precision medicine. PMID:26776196

    2014-01-01

    In general, around 80% of all strokes are ischemic. Take caring of the patients who have suffered an ischemic stroke is both expensive and time consuming. It is known that thrombolysis in patients with ischemic stroke can reduce the disability and increase the survival rate, however some patients still have poor outcomes. Therefore, to be able to predict the outcome of ischemic stroke patients after intravenous thrombolysis would be useful while making clinical decisions. In this study, we collected retrospective data of 82 ischemic stroke patients who received intravenous thrombolysis from July 2005 to June 2012 in Tri-service General Hospital. Of these patients, 10 died within 3 months, and only 36 patients made a good recovery. We used STATISTICA 10 software to select the best artificial neural network. The parameters of model 1 were age, blood sugar, onset to treatment time, National Institute of Health Stroke Scale (NIHSS) score, dense cerebral artery sign, and old stroke to predict 3-month outcomes. The parameters of model 2 were age, onset to treatment time, NIHSS score, hypertension, heart disease, diabetes and old stroke to predict the 3-month prognosis. The sensitivity, specificity and accuracy for model 1 were 77.78%, 80.43% and 79.27%, respectively, and 94.44%, 95.65% and 95.12%, respectively, for model 2. Artificial neural networks are used to establish prediction models with good performance to predict thrombolysis outcomes. These models may be able to help physicians to discuss and explain the likely outcomes to patients and their families before thrombolysis treatment. PMID:25000029

  7. Sensori-neural hearing loss in patients treated with irradiation for nasopharyngeal carcinoma

    International Nuclear Information System (INIS)

    The present investigation has been carried out to evaluate the sensitivity of the inner ear to irradiation. Cochlear function was tested in a cohort of 22 patients before and 7-84 months after receiving external irradiation for nasopharyngeal carcinoma. The pre-irradiation sensori-neural hearing threshold at 500, 1000, 2000, and 4000 Hz was used as a baseline for the individual patient, and the observed sensori-neural hearing loss (SNHL) was calculated as the difference between pre- and post-irradiation values. The pre-irradiation hearing level or patient age was not correlated with the actual SNHL. In contrast, there was a significant correlation between the total radiation dose to the inner ear and the observed hearing impairment. SNHL was most pronounced in the high frequencies, with values up to 35 dB (4000 Hz) and 25 dB (2000 Hz) in some patients. The latent period for the complication appeared to be 12 months or more. The deleterious effect of irradiation on the hearing should be kept in mind both in treatment planning and in the follow-up after radiotherapy

    This article reviews updates and provides some data related to nutritional and orthomolecular supplementation in oncology patients with an emphasis on lung cancer, a commonly diagnosed tumor with significant nutritional disturbances. Cancer and its treatment play a significant role in nutritional imbalance which likely has negative impact on the patient both in terms of quality and quantity of life. Nutritional supplementation may correct these imbalances with significant clinical benefit both physiologically and psychologically. This review will help assist in providing clinically useful data to assess the cancer patient's nutritional status and to guide nutritional intervention to assist these patients' recovery.

    The prevalence of germline pathogenic mutations in a comprehensive panel of cancer predisposition genes is not well defined for patients with pancreatic ductal adenocarcinoma (PDAC). To estimate the frequency of mutations in a panel of 22 cancer predisposition genes, 96 patients unselected for a family history of cancer who were recruited to the Mayo Clinic Pancreatic Cancer patient registry over a 12 month period were screened by next-generation sequencing. Fourteen pathogenic mutations in 13 patients (13.5%) were identified in eight genes: four in ATM, two in BRCA2, CHEK2, and MSH6, and one in BARD1, BRCA1, FANCM, and NBN. These included nine mutations (9.4%) in established pancreatic cancer genes. Three mutations were found in patients with a first degree relative with PDAC, and 10 mutations were found in patients with first or second-degree relatives with breast, pancreas, colorectal, ovarian, or endometrial cancer. These results suggest that a substantial proportion of patients with PDAC carry germline mutations in predisposition genes associated with other cancers, and that a better understanding of pancreatic cancer risk will depend on evaluation of families with broad constellations of tumors. These findings highlight the need for recommendations governing germline gene-panel testing of pancreatic cancer patients. PMID:26483394

    Full Text Available BACKGROUND: To evaluate the impact of diabetes on outcomes in colorectal cancer patients and to examine whether this association varies by the location of tumor (colon vs. rectum. PATIENTS AND METHODS: This study includes 4,131 stage I-III colorectal cancer patients, treated between 1995 and 2007 (12.5% diabetic, 53% colon, 47% rectal in South Korea. Cox proportional hazards modeling was used to determine the prognostic influence of DM on survival endpoints. RESULTS: Colorectal cancer patients with DM had significantly worse disease-free survival (DFS [hazard ratio (HR 1.17, 95% confidence interval (CI: 1.00-1.37] compared with patients without DM. When considering colon and rectal cancer independently, DM was significantly associated with worse overall survival (OS (HR: 1.46, 95% CI: 1.11-1.92, DFS (HR: 1.45, 95% CI: 1.15-1.84 and recurrence-free survival (RFS (HR: 1.32, 95% CI: 0.98-1.76 in colon cancer patients. No association for OS, DFS or RFS was observed in rectal cancer patients. There was significant interaction of location of tumor (colon vs. rectal cancer with DM on OS (P = 0.009 and DFS (P = 0.007. CONCLUSIONS: This study suggests that DM negatively impacts survival outcomes of patients with colon cancer but not rectal cancer.

  17. Cultural beliefs and values in cancer patients.

    Science.gov (United States)

    Daher, M

    2012-04-01

    In 2008, the International Agency for Research on Cancer (IARC) released its World Cancer Report, which indicated that cancer accounts for approximately 12% of all-cause mortality worldwide. IARC estimated that globally 7.6 million people died from cancer and that 12.4 million new cases were diagnosed in 2008. The report went on to project that, due to increases in life expectancy, improvements in clinical diagnostics, and shifting trends in health behaviors (e.g. increases in smoking and sedentary lifestyles), in the absence of significant efforts to improve global cancer control, cancer mortality could increase to 12.9 million and cancer incidence to 20 million by the year 2030. Looking deeper into the data, it becomes clear that cancer-related stigma and myths about cancer are important problems that must be addressed, although different from a country to another. Stigmas about cancer present significant challenges to cancer control: stigma can have a silencing effect, whereby efforts to increase cancer awareness are negatively affected. The social, emotional, and financial devastation that all too often accompanies a diagnosis of cancer is, in large part, due to the cultural myths and taboos surrounding the disease. Combating stigma, myths, taboos, and overcoming silence will play important roles in changing this provisional trajectory. There are several reasons that cancer is stigmatized. Many people in our area perceived cancer to be a fatal disease. Cancer symptoms or body parts affected by the disease can cultivate stigma. Fears about treatment can also fuel stigma. There was evidence of myths associated with cancer, such as the belief that cancer is contagious, or cancer may be seen as a punishment. After reviewing these different examples of cultural myths and taboos met in cancer care, we can report these lessons learned: 1. Around the world, cancer continues to carry a significant amount of stigma, myths, and taboos; however, there are opportunities to

    2016-01-01

    Online social network technologies have become important to health and apply in most health care areas. Particularly in cancer care, because it is a disease which involves many social aspects, online social networks can be very useful. Use of online social networks provides a suitable platform for cancer patients and families to present and share information about their medical conditions, address their educational needs, support decision making, and help to coping with their disease and improve their own outcomes. Like any other new technologies, online social networks, along with many benefits, have some negative effects such as violation of privacy and publication of incorrect information. However, if these effects are managed properly, they can empower patients to manage cancer through changing behavioral patterns and enhancing the quality of cancer patients lives This paper explains some application of online social networks in the cancer patient care process. It also covers advantages and disadvantages of related technologies. PMID:27039815

  10. Neural correlates of emotion regulation in patients with schizophrenia and non-affected siblings.

    Directory of Open Access Journals (Sweden)

    Lisette van der Meer

    Full Text Available BACKGROUND: Patients with schizophrenia often experience problems regulating their emotions. Non-affected relatives show similar difficulties, although to a lesser extent, and the neural basis of such difficulties remains to be elucidated. In the current paper we investigated whether schizophrenia patients, non-affected siblings and healthy controls (HC exhibit differences in brain activation during emotion regulation. METHODS: All subjects (n = 20 per group performed an emotion regulation task while they were in an fMRI scanner. The task contained two experimental conditions for the down-regulation of emotions (reappraise and suppress, in which IAPS pictures were used to generate a negative affect. We also assessed whether the groups differed in emotion regulation strategies used in daily life by means of the emotion regulation questionnaire (ERQ. RESULTS: Though the overall negative affect was higher for patients as well as for siblings compared to HC for all conditions, all groups reported decreased negative affect after both regulation conditions. Nonetheless, neuroimaging results showed hypoactivation relative to HC in VLPFC, insula, middle temporal gyrus, caudate and thalamus for patients when reappraising negative pictures. In siblings, the same pattern was evident as in patients, but only in cortical areas. CONCLUSIONS: Given that all groups performed similarly on the emotion regulation task, but differed in overall negative affect ratings and brain activation, our findings suggest reduced levels of emotion regulation processing in neural circuits in patients with schizophrenia. Notably, this also holds for siblings, albeit to a lesser extent, indicating that it may be part and parcel of a vulnerability for psychosis.

  14. Radiation induced chromosomal instability in lymphocytes of cancer patients

    International Nuclear Information System (INIS)

    Full text: Cytokinesis-blocked micronucleus (CBMN) assay has been extensively used to evaluate the radiation sensitivity of human individuals. Using the CBMN assay, Scott et al (1998, 1999) demonstrated that a fraction of radiosensitive individuals in breast cancer case population was larger than in normal individual population. However, Vral et al were very skeptical about the Scott et al's findings (2002). Under the approval from the ethical committee of NIRS, peripheral blood was obtained from 46 normal healthy females, 131 breast cancer patients, 32 cervical cancer patients and 7 female head and neck cancer patients. Radiosensitivity of T-lymphocytes was assessed by using a CBMN assay. The frequencies of MN per binucleated cell in healthy donors were 0.031(±0.010) and 0.151(±0.066) for cells treated before and after X-ray-irradiation (2Gy), respectively. Spontaneous MN frequencies in cancer patients were significantly higher than healthy donors (p < 0.001). Radiation sensitivities of breast- and head and neck-cancer patients were significantly higher than normal individuals (p < 0.001). Cervical cancer patients were more resistant to irradiation than healthy donors, though the number of cases for statistical analysis was small. (p < 0.001). We are considering that the HPV infection affected the radiosensitivity of cervical cancer cases. Because it is widely believed that one key mechanism which leads to spontaneous micronucleus formation involves an imbalance of chromosomal segregation and a chromosomal instability in patients' lymphocytes might be greater than that in normal individuals' lymphocytes. Recently, Kuschel et al (2002) demonstrated that ratios in two SNPs on XRCC3 were significantly different between cancer patients and healthy females. Then, we can suppose that the radiation-related genes with low penetrance may be involved in tumorigenesis of mammary- and head and neck-cells, and also, in patients' radiation susceptibility

    2012-01-01

    Purpose: Previous studies have reported a significant number of patients with breast cancer seek cancer-related information from the Internet. Most studies have asked whether a patient has ever read Internet information since her diagnosis. The purpose of this study was to assess the frequency with which patients with breast cancer come to physician appointments having recently read and intending to discuss cancer-related information from the Internet. Patients and Methods: We asked 558 patients with breast cancer who were waiting to see their physicians about their experiences reading cancer-related information from the Internet and their intent to discuss the information in their current visit. Results: Fifteen percent reported reading cancer-related Internet information in the past month. Patients who had read such information in the past month were younger, had been diagnosed more recently, and were more likely to be attending a new visit. Of those who had read in the past month, 45% reported intending to discuss what they had read with their physician. Nineteen percent of patients reported having ever read breast cancer–related Internet information since their diagnosis. Conclusion: The proportion of patients with breast cancer planning to discuss Internet information during their current physician visit was relatively small. Few characteristics were associated with recent Internet use or intent to discuss. PMID:22548010

    2013-03-01

    Full Text Available Developments in methods of early diagnostic and treatment of cancer have increased the rate of survival. However, research also indicates that there has been an increase in the costs to health care system caused by both post-treatment of the disease itself and the possible psychosocial problems associated with the therapy. This evaluation stresses the importance of long-term post-treatment monitoring of cancer patients and emphasizes necessity of ensuring continuity of care. Sustainable long-term treatment and care procedures for the cancer survival patients have been developed in accordance with international regulations. The psychosocial services for cancer patients offered in our country are inadequate as these are at an early stage of development. However, establishment of organizations and coordination of various consultancy services for this group of patients can lead to prevention of workforce loss and other costs, as well as raise the quality of life for these patients.

    Maitake mushroom (Grifola frondosa) MD-fraction containing beta-1,6 glucan with beta-1,3 branched chains has previously exhibited strong anticancer activity by increasing immune-competent cell activity.1,2 In this non-random case series, a combination of MD-fraction and whole maitake powder was investigated to determine its effectiveness for 22- to 57-year-old cancer patients in stages II-IV. Cancer regression or significant symptom improvement was observed in 58.3 percent of liver cancer patients, 68.8 percent of breast cancer patients, and 62.5 percent of lung cancer patients. The trial found a less than 10-20 percent improvement for leukemia, stomach cancer, and brain cancer patients. Furthermore, when maitake was taken in addition to chemotherapy, immune-competent cell activities were enhanced 1.2-1.4 times, compared with chemotherapy alone. Animal studies have supported the use of maitake MD-fraction for cancer. PMID:12126464

Little is known about tilt testing (TT, carotid sinus massage (CSM, or supine and upright blood pressure measurement related to age or about patients with complex diagnoses, for example, those with a double diagnosis, ie, positivity in two of these three tests. Methods: A total of 873 consecutive patients of mean age 66.5±18 years underwent TT, CSM, and blood pressure measurement in the supine and upright positions according to the European Society of Cardiology guidelines on syncope.1 Neuroautonomic evaluation was performed if the first-line evaluation (clinical history, physical examination, electrocardiogram was suggestive of neurally mediated syncope, or if the first-line evaluation was suggestive of cardiac syncope but this diagnosis was excluded after specific diagnostic tests according to European Society of Cardiology guidelines on syncope, or if certain or suspected diagnostic criteria were not present after the first-line evaluation. Results: A diagnosis was reached in 64.3% of cases. TT was diagnostic in 50.4% of cases, CSM was diagnostic in 11.8% of cases, and orthostatic hypotension was present in 19.9% of cases. Predictors of a positive tilt test were prodromal symptoms and typical situational syncope. Increased age and a pathologic electrocardiogram were predictors of carotid sinus syndrome. Varicose veins and alpha-receptor blockers, nitrates, and benzodiazepines were associated with orthostatic hypotension. Twenty-three percent of the patients had a complex diagnosis.

The aim of this study was to examine the prevalence of COPD and emphysema at the time of primary lung cancer diagnosis and to examine factors associated with survival.  Materials and methods: Medical records, pulmonary function tests, and computed tomography scans were used to determine the presence of COPD and emphysema in patients diagnosed with primary lung cancer at the University Hospital of North Norway in 2008–2010.  Results: Among the 174 lung cancer patients, 69% had COPD or emphysema (39% with COPD, 59% with emphysema; male:female ratio 101:73. Neither COPD nor emphysema were significantly associated with lung cancer mortality, whereas patients with non-small-cell lung cancer other than adenocarcinoma and squamous cell carcinoma had a risk of lung cancer mortality that was more than four times higher than that of patients with small-cell lung cancer (hazard ratio [HR] 4.19, 95% confidence interval [CI] 1.56–11.25. Females had a lower risk of lung cancer mortality than males (HR 0.63, 95% CI 0.42–0.94, and patients aged ≥75 years had a risk that was twice that of patients aged <75 years (HR 2.48, 95% CI 1.59–3.87. Low partial arterial oxygen pressure (4.0–8.4 kPa increased the risk of lung cancer mortality (HR 2.26, 95% CI 1.29–3.96.

    Full Text Available Depression is a common symptom in cancer patients, which is difficult to be detected and consequently to be treated. It deteriorates over the course of cancer treatment, persists long after the end of therapy and influences negatively the quality of life. The aim of this study was to examine the prevalence rate and level anxiety and depression in breast cancer patient using HAD scale.The study was conducted on 94 female patients suffering from various stages of breast cancer. Patients included who were in the age group between 18-65yrs, estimated survival time more than six months, ability to speak and patients were excluded if they were affected by known mental disorder and metastasis in brain. Demographic data was collected from each patient’s medical record e.g. cancer type, date of cancer diagnosis, extension of the diseases, sites of metastasis, estimated life time. Levels of anxiety and depression were self rated by HADS (hospital anxiety and depression scaleOut of 94 patients twenty patients (21% were reported as mild depression (mean score 8.93 and 23 (24% patients as mild anxiety (mean score 9.42 likewise five Patients were reported as (positive cases chronic depression (mean score is 12.23 and six patients as chronic anxiety.(mean score is 12.23 The results of this present study clearly demonstrated that prevalence of anxiety and depression rates depended on the patients’ educational level, age, occupation, menopause and diagnosis period. Our study found that the depression and anxiety were common in most of the patients affected with breast cancer is also there was no relation between the anxiety and depression and stages of diseases. We think that this study needs to be extended in the future to involve more patient is may be further be tested to evaluate the same sample again, after psychiatric intervention is carried out.

  5. Caring for cancer patients on non-specialist wards.

    As cancer is the leading cause of death worldwide, every nurse will be required to care for patients with the condition at some point in his\\/her career. However, non-specialized oncology nurses are often ill-prepared to nurse patients suffering from cancer. This literature review aims to provide an overview of current trends and developments in cancer care nursing in an attempt to identify the range of previous research pertaining to caring for patients with cancer on non-specialist wards. The review finds that non-specialized cancer nurses report a lack of education and training with regard to cancer care and cancer treatments, which acts as a barrier to providing quality nursing care. Emotional and communication issues with patients and their families can also cause non-specialist nurses significant distress. International research has shown that specialist oncology nurses make a considerable difference to physical and psychosocial patient care. It is therefore paramount that non-speciality nurses\\' educational needs are met to develop clinical competence and to provide supportive holistic care for both patients and their families.

  6. LMWH in cancer patients with renal impairment - better than warfarin?

    2016-04-01

    Venous thromboembolism (VTE) is one of the leading causes of death in cancer patients, which are known to have a 5- to 7-fold increased risk for VTE. The anticoagulant treatment of VTE in cancer patients is less effective with a three-fold increased risk of VTE recurrence compared to non-cancer patients, and it is less safe with more than double rates of major bleeding. Compared to vitamin-K antagonists (VKA), long-term secondary prevention with low molecular weight heparin (LMWH) has been shown to reduce the risk of recurrent VTE in cancer-associated thrombosis (CAT), and therefore, current international guidelines recommend the use of LMWH over VKA. With increasing age, cancer prevalence and VTE incidence increase while renal function decreases. Anti-cancer treatment may impair renal function additionally. Therefore, renal insufficiency is a frequent challenge in CAT patients, which is associated with a higher risk of both bleeding and recurrent VTE. Both VKA and LMWH may be associated with less efficacy and higher bleeding risk in renal insufficiency. Unfortunately, there is a lack of prospective data on renal insufficiency and CAT. A recent sub-analysis from a large randomized controlled trial shows that the bleeding risk in patients with severe renal insufficiency in CAT is not elevated with the use of LMWH compared to VKA while efficacy is maintained. In addition, LMWH treatment has several practical advantages over VKA, particularly in patients with CAT while they are receiving anti-cancer treatment. PMID:27067971

    Full Text Available This paper attempts to improve the efficiency of the system that proposed in [1] to determine whether a given skin lesion microscopic image is malignant or benign; in case of malignancy, the system can specify its type; whether it is squamous cell carcinoma or basal cell carcinoma (the two leading skin cancer types. The testing of this system was conducted using 80 microscopic images of skin tissues of the types normal, benign and the two types of skin cancer (squamous and basal; the images have been collected from different hospital pathology departments as part of the research work. Some of the collected samples have been used as training and others as testing materials. The proposed system consists of 3 main steps. First, extraction of a set of textural descriptors to localize the abnormal visual attributes which may appear in the tested skin tissue images. Second, selection of the best discriminating texture features. Third, identify the type of skin tissue images using artificial neural network (ANN. In the training phase, the system was trained using 50 skin tissue images, the textural features extracted from training samples were analyzed and their discrimination powers were evaluated in order to get a list of the most suitable features for auto recognition task. When ANN is trained on co-occurrence features the attained allocation accuracy rates was (%97.71 and the diagnosis accuracy rate was (%98.75. While when using ANN with combinations of different types of textural features; the allocation accuracy rate reached to (%97.90 while the diagnosis accuracy rate became (%98.75

    Patients in vulnerable population groups suffer disproportionately from cancer. The elimination of cancer disparities is critically important for lessening the burden of cancer. Patient navigator programs have been shown to improve clinical outcomes. Among its provisions relevant to disparities in cancer care, The Patient Protection and Affordability Care Act authorizes continued funding of patient navigator programs. However, given the current economic and political environment, this funding is in jeopardy. This article describes patient navigator programs and summarizes the elements of the health care law that are relevant to these programs. It is vital that the entire oncology community remain committed to leading efforts toward the improvement of cancer care among our most vulnerable patients. PMID:21804070

    In Italy, educational programs for cancer patients are currently provided by the national government, scientific societies, and patient advocate organizations. Several gaps limit their effectiveness, including the lack of coordinated efforts, poor involvement of patient feedback in the planning of programs, as well as a lack of resources on innovative cancer-related topics. This process is parallel to a strong shift in the attitude of patients towards health in general and taking charge of their own health conditions in particular. The National Cancer Institute in the USA and the Organization of European Cancer Institutes encourage comprehensive cancer centers in providing educational programs conceived to overcome these gaps. The goal of this paper is to identify and describe the key elements necessary to develop a global patient education program and provide recommendations for strategies with practical examples for implementation in the daily activities of cancer institutes. A multidisciplinary committee was established for patient education, including patient representatives as equal partners, to define, implement, verify, and evaluate the fundamental steps for establishing a comprehensive education program. Six essential topics were identified for the program: appropriate communication of cancer epidemiology, clinical trial information, new therapeutic technologies, support in the use of medicines, psycho-oncological interventions, age-personalized approaches, and training programs for healthcare providers. Integration of these topics along with patient feedback is the key to a successful model for educational programs. An integrated educational program can transform a comprehensive cancer center to an institution that provides research and care for and with patients. PMID:25773134

    The life expectancy of people with type 1 diabetes is improving and now approaches that of those without diabetes. As this population ages, a growing number will be diagnosed with and treated for cancer. Cancer treatments can drastically affect insulin requirement and glycemic control through multiple mechanisms including high doses of glucocorticoids and targeted therapies that directly interfere with cellular pathways involved in the action of insulin. Patients with cancer frequently also have alterations in gastrointestinal motility or appetite and require supplemental enteral or parenteral nutrition. Few studies have evaluated these patients directly, but data on patients with and without diabetes suggest that glycemic control may play a larger role in cancer outcomes than is often recognized. Collaboration between the treating oncologist and diabetologist allows people with diabetes to receive the most effective therapies for their cancers without undue risk of hypoglycemia or adverse outcomes due to hyperglycemia.

    A recent review showed frequent reductions of sorafenib dose in the treatment of metastatic thyroid cancer because of toxicity consistent with the findings of the phase III DECISION trial and contrasting with the safety of sorafenib in other cancer populations. The unexpected excess of toxicity observed in thyroid cancer patients may be linked to a high prevalence of sarcopenia in this population, resulting in frequent overexposure to sorafenib.

    Studies for the association between diseases and informative single nucleotide polymorphisms (SNPs) have received great attention. However, most of them just use the whole set of useful SNPs and fail to consider the SNP-SNP interactions, while these interactions have already been proven in biology experiments. In this paper, we use a binary particle swarm optimization with hierarchical structure (BPSOHS) algorithm to improve the effective of PSO for the identification of the SNP-SNP interactions. Furthermore, in order to use these SNP interactions in the susceptibility analysis, we propose an emotional neural network (ENN) to treat SNP interactions as emotional tendency. Different from the normal architecture, just as the emotional brain, this architecture provides a specific path to treat the emotional value, by which the SNP interactions can be considered more quickly and directly. The ENN helps us use the prior knowledge about the SNP interactions and other influence factors together. Finally, the experimental results prove that the proposed BPSOHS_ENN algorithm can detect the informative SNP-SNP interaction and predict the breast cancer risk with a much higher accuracy than existing methods.

    Background. Multivariate models are used to increase prostate cancer (PCa) detection rate and to reduce unnecessary biopsies. An external validation of the artificial neural network (ANN) "ProstataClass" (ANN-Charité) was performed with daily routine data. Materials and Methods. The individual ANN predictions were generated with the use of the ANN application for PSA and free PSA assays, which rely on age, tPSA, %fPSA, prostate volume, and DRE (ANN-Charité). Diagnostic validity of tPSA, %fPSA, and the ANN was evaluated by ROC curve analysis and comparisons of observed versus predicted probabilities. Results. Overall, 101 (35.8%) PCa were detected. The areas under the ROC curve (AUCs) were 0.501 for tPSA, 0.669 for %fPSA, 0.694 for ANN-Charité, 0.713 for nomogram I, and 0.742 for nomogram II, showing a significant advantage for nomogram II (P = 0.009) compared with %fPSA while the other model did not differ from %fPSA (P = 0.15 and P = 0.41). All models overestimated the predicted PCa probability. Conclusions. Beside ROC analysis, calibration is an important tool to determine the true value of using a model in clinical practice. The worth of multivariate models is limited when external validations were performed without knowledge of the circumstances of the model's development. PMID:22830050

    Full Text Available Although numerous genetic mutations and amplifications have been identified in pancreatic cancer, much of the molecular pathogenesis of the disease remains undefined. While proteomic and transcriptomic analyses have been utilized to probe and characterize pancreatic tumors, lipidomic analyses have not been applied to identify perturbations in pancreatic cancer patient samples. Thus, we utilized a mass spectrometry-based lipidomic approach, focused towards the sphingolipid class of lipids, to quantify changes in human pancreatic cancer tumor and plasma specimens. Subgroup analysis revealed that patients with positive lymph node metastasis have a markedly higher level of ceramide species (C16:0 and C24:1 in their tumor specimens compared to pancreatic cancer patients without nodal disease or to patients with pancreatitis. Also of interest, ceramide metabolites, including phosphorylated (sphingosine- and sphinganine-1-phosphate and glycosylated (cerebroside species were elevated in the plasma, but not the pancreas, of pancreatic cancer patients with nodal disease. Analysis of plasma level of cytokine and growth factors revealed that IL-6, IL-8, CCL11 (eotaxin, EGF and IP10 (interferon inducible protein 10, CXCL10 were elevated in patients with positive lymph nodes metastasis, but that only IP10 and EGF directly correlated with several sphingolipid changes. Taken together, these data indicate that sphingolipid metabolism is altered in human pancreatic cancer and associated with advanced disease. Assessing plasma and/or tissue sphingolipids could potentially risk stratify patients in the clinical setting.

    Objective: To evaluate the effects of hyperbaric oxygen (HBO) therapy on patients with postbrain injury neural status.Methods: Two to 4 courses of HBO therapy and/or medications were used to treat 320 patients who were randomly divided into two groups. Assessment was made with 99mTc-ethyl cysteinate dimer (99mTc-ECD) single photon emission computed tomography (SPECT) before and after treatment. Results: There was a significant difference between the HBO therapy group and the non-HBO therapy group. HBO therapy was superior to medication treatment alone in the recovery of clinical symptoms, control of epilepsy, and resolution of hydrocephalus (P<0.01). Conclusions: HBO therapy has specific curative effects on patients with postbrain injury neural status, and 99mTc-ECD SPECT could play an important role in diagnosing postbrain injury neural status and monitoring the therapeutic effects of HBO.

Mirror neuron system (MNS has been studied widely in humans in stroke and phantom sensations. Materials and Methods: Study subjects included 20 patients with chronic stroke and 10 healthy controls. Patients had clinical disease-severity scores, functional magnetic resonance imaging (fMRI and diffuse tensor imaging (DTI at baseline, 8 and at 24 weeks. Block design with alternate baseline and activation cycles was used with a total of 90 whole brain echo planar imaging (EPI measurements (timed repetition (TR = 4520 ms, timed echo (TE = 44 ms, slices = 31, slice thickness = 4 mm, EPI factor 127, matrix = 128 × 128, FOV = 230 mm. Whole brain T1-weighted images were acquired using 3D sequence (MPRage with 120 contiguous slices of 1.0 mm thickness. The mirror therapy was aimed via laptop system integrated with web camera, mirroring the movement of the unaffected hand. This therapy was administered for 5 days in a week for 60-90 min for 8 weeks. Results: All the patients showed statistical significant improvement in Fugl Meyer and modified Barthel Index (P < 0.05 whereas the change in Medical Research Council (MRC power grade was not significant post-therapy (8 weeks. There was an increase in the laterality index (LI of ipsilesional BA 4 and BA 6 at 8 weeks exhibiting recruitment and focusing principles of neural plasticity. Conclusions: Mirror therapy simulated the "action-observation" hypothesis exhibiting recovery in patients with chronic stroke.

    Rehder, Douglas S; Nelson, Randall W; Borges, Chad R

    2009-10-01

    On the basis of the results of activity studies, previous reports have suggested that vitamin D binding protein (DBP) is significantly or even completely deglycosylated in cancer patients, eliminating the molecular precursor of the immunologically important Gc macrophage activating factor (GcMAF), a glycosidase-derived product of DBP. The purpose of this investigation was to directly determine the relative degree of O-linked trisaccharide glycosylation of serum-derived DBP in human breast, colorectal, pancreatic, and prostate cancer patients. Results obtained by electrospray ionization-based mass spectrometric immunoassay showed that there was no significant depletion of DBP trisaccharide glycosylation in the 56 cancer patients examined relative to healthy controls. These results suggest that alternative hypotheses regarding the molecular and/or structural origins of GcMAF must be considered to explain the relative inability of cancer patient serum to activate macrophages.

    2014-10-01

    Full Text Available Venous thromboembolism is a frequent and serious complication in patients with cancer. It is an independent prognostic factor of death in cancer patients and the second leading cause of death, but physicians often underestimate its importance, as well as the need for adequate prevention and treatment. Management of venous thromboembolism in patients with cancer requires the coordinated efforts of a wide range of clinicians, highlighting the importance of a multidisciplinary approach. However, a lack of consensus among various national and international clinical practice guidelines has contributed to knowledge and practice gaps among practitioners, and inconsistent approaches to venous thromboembolism. The 2013 international guidelines for thrombosis in cancer have sought to address these gaps by critically re-evaluating the evidence coming from clinical trials and synthesizing a number of guidelines documents. An individualized approach to prophylaxis is recommended for all patients.

    Folate deficiency during early embryonic development constitutes a risk factor for neural tube defects and potentially for childhood leukemia via unknown mechanisms. We tested whether folate consumption during the 12 months prior to conception induced DNA methylation modifications at birth in healthy neonates with a genome-wide and agnostic approach. We hypothesized that DNA methylation in genes involved in neural tube development and/or cancer susceptibility would be affected by folate exposure. We retrospectively assessed folate exposure at the time of conception by food-frequency questionnaires administered to the mothers of 343 healthy newborns. We measured genome-wide DNA methylation from neonatal blood spots. We implemented a method based on bootstrap resampling to decrease false-positive findings. Folate was inversely associated with DNA methylation throughout the genome. Among the top folate-associated genes that were replicated in an independent Gambian study were TFAP2A, a gene critical for neural crest development, STX11, a gene implicated in acute myeloid leukemia, and CYS1, a candidate gene for cystic kidney disease. Reduced periconceptional folate intake was associated with increased methylation and, in turn, decreased gene expression at these 3 loci. The top folate-sensitive genes defined by their associated CpG sites were enriched for numerous transcription factors by Gene Set Enrichment Analysis, including those implicated in cancer development (e.g., MYC-associated zinc finger protein). The influence of estimated periconceptional folate intake on neonatal DNA methylation levels provides potential mechanistic insights into the role of this vitamin in the development of neural tube defects and childhood cancers.

    2016-06-01

    Recently, RECQL was reported as a new breast cancer susceptibility gene. RECQL belongs to the RECQ DNA helicase family which unwinds double strand DNA and involved in the DNA replication stress response, telomere maintenance and DNA repair. RECQL deficient mice cells are prone to spontaneous chromosomal instability and aneuploidy, suggesting a tumor-suppressive role of RECQL in cancer. In this study, RECQL gene mutation screening was performed on 1110 breast cancer patients who were negative for BRCA1, BRCA2, TP53 and PTEN gene mutations and recruited from March 2007 to June 2015 in the Hong Kong Hereditary and High Risk Breast Cancer Program. Four different RECQL pathogenic mutations were identified in six of the 1110 (0.54 %) tested breast cancer patients. The identified mutations include one frame-shift deletion (c.974_977delAAGA), two splicing site mutations (c.394+1G>A, c.867+1G>T) and one nonsense mutation (c.796C>T, p.Gln266Ter). Two of the mutations (c.867+1G>T and p.Gln266Ter) were seen in more than one patients. This study provides the basis for existing of pathogenic RECQL mutations in Southern Chinese breast cancer patients. The significance of rare variants in RECQL gene in the estimation of breast cancer risk warranted further investigation in larger cohort of patients and in other ethnic groups. PMID:27125668

    Full Text Available Abstract Background In the past few years, the number of clinical trials has increased rapidly in East Asia, especially for gastric and hepatobiliary cancer that are prevalent in Asian populations. However, the actual degree of understanding or perceptions of clinical trials by cancer patients in East Asian countries have seldom been studied. Methods Between July 1st and November 30th of 2011, we conducted a prospective study to survey cancer patients regarding their awareness of, and willingness to participate in, a clinical trial. Patients with gastrointestinal/hepatobiliary cancer who visited the Hematology-Oncology outpatient clinic at Samsung Medical Center (SMC were enrolled. A total of 21 questions were asked including four questions which used the Visual analogue scale (VAS score. Results In this survey study, 1,000 patients were asked to participate and 675 patients consented to participate (67.5%. The awareness of clinical trials was substantially higher in patients who had a higher level of education (pp=0.004, and had a higher economic status (p=0.001. However, the willingness to participate in a clinical trial was not affected by the level of education or economic status of patients. The most influential factors for patient willingness to participate were a physician recommendation (n=181, 26.8%, limited treatment options (n=178, 26.4%, and expectations of effectiveness of new anti-cancer drugs (n=142, 21.0%. Patients with previous experience in clinical trials had a greater willingness to participate in clinical trials compared to patients without previous experience (p Conclusions This large patient cohort survey study showed that Korean cancer patients are more aware of clinical trials, but awareness did not translate into willingness to participate.

  6. Radiotherapy for superficial esophageal cancer of poor risk patients

    International Nuclear Information System (INIS)

    Purpose/Objective: The reported incidence of superficial esophageal cancer (SEC) has steadily increased in Japan as result of endoscopic examination has been become common. In Japan, treatment of SEC is endoscopical mucosal resection (EMR) for mucosal cancer or esophagectomy with 3 fields lymph nodes resection for submucosal cancer. Radiotherapy is little place for the management of SEC. Because of some reasons, we treated patients with SEC by radiotherapy alternative to surgery. Purpose of this report is to evaluate efficacy of radiotherapy for SEC. Methods and Materials: Between 1989 to 1996, eighteen patients with SEC were treated with radiotherapy at our hospital. Reasons of radiotherapy that was chosen as the primary methods of treatment were refusal of surgery in one patient, poor medical condition in 4 patients and double primary cancer in 13 patients (head and neck: 11, simultaneously: 11). No patients had indication of EMR. Diagnosis was made by endoscopy and radiography. Some patients were examined with endoscopic ultrasound. Two patients (11.1%) had tumor limited to the mucosa and 16 patients (88.9%) had tumor invaded the submucosa. Seven of these tumors (38.9%) were multicentric. All patients had squamous cell carcinoma. There were 17 male patients and one female patient. The age range was 49 years to 87 years with a median of 62 years. Stage of all patients was T1N0M0 according to UICC staging system. Ten patients underwent external radiotherapy (Ex) (50 Gy - 66 Gy) alone and 8 patients did both Ex and intracavitary radiotherapy (IC) (30-60 Gy of Ex with 5-15 Gy of IC). No patients received chemotherapy. Duration of follow-up was 6 months to 96 months with a median of 30 months. Results: The overall survival rate was 55.9% in 3-year and 14% in 5-year, and the cause-specific 5-year survival rate was 100%. Causes of death were malignant tumor other than esophageal cancer in 4 patients, intercurrent disease other than malignant tumor in 3 patients and no

Ten most common non-medical sources of developing psychological disorders were identified. It was observed that family support system and general home atmosphere were significantly associated with the development of psychological disorders whereas the other variables such as age, gender and marital status had no significant relationship with the non Medical factors. Conclusion: It was concluded that non-medical factors causing psychological problems are significant in cancer patients. The results suggest that we should identify these factors and target psychosocial intervention for those patients most at risk. (author)

  1. POSTOPERATIVE HYPERGLYCAEMIA IN NON-DIABETIC INDIAN CANCER PATIENTS

    Directory of Open Access Journals (Sweden)

    Pampanagouda

    2016-03-01

    Full Text Available There is limited data available in the literature about the hyperglycaemic response in cancer patients in the postoperative period. Hyperglycaemia resulting from insulin resistance is common in critically ill patients including those who have not previously been diagnosed with diabetes. We tried to analyse the glycaemic response in different cancer patients in the postoperative period, so that this information can be analysed to look for any correlation between the glycaemic response and the surgical outcome, in particular cancer patients. Prospectively, the postoperative blood glucose level was measured at different intervals. Hyperglycaemic response was more at 6th hour and gradually declined over next 72 hours. Hyperglycaemic response was more in carcinoma oesophagus patients and least in thyroid patients. The stress of surgery itself results in metabolic perturbations that alter glucose homeostasis. Persistent hyperglycaemia is a risk factor for endothelial dysfunction, impaired phagocytosis and immunity, oxidative stress, abnormal lipid metabolism, decreased vascular contractility, increased platelet adhesiveness and increased C-reactive protein levels, consequently resulting in cardiovascular morbidity, postoperative sepsis and impaired wound healing. Patients with cancer respond differently to stress and this knowledge might help in the future to develop strategies to reduce and treat during the postoperative period. OBJECTIVE To study the pattern of glycaemic variation in patients with different Cancers during the postoperative period.

  5. Cardiovascular risk during hormonal treatment in patients with prostate cancer

    International Nuclear Information System (INIS)

    The objective of this review is to provide information on cardiovascular risk following androgen-deprivation therapy (ADT) in prostate cancer patients and to suggest potential prevention and management strategies. Androgen deprivation therapy can cause peripheral insulin resistance, increase fat mass and low-density lipoprotein cholesterol, and induce type 2 diabetes. While recent studies have reported an association in patients with prostate cancer between ADT and increased risk of cardiovascular events, other studies have not detected the association. However, at this time, it is plausible that ADT could increase cardiovascular risk because of the adverse effect of ADT on risk factors for cardiovascular disease. It is advisable that prostate cancer patients in whom ADT is initiated be referred to their physician, who will carefully monitor them for potential metabolic effects. Therefore, physicians should be informed about these potential side effects. This especially applies to men aged >65 years and those with pre-existing cardiovascular comorbidities. Adopting a healthy lifestyle including a balanced diet and regular physical activity is recommended. Patients with cardiovascular disease should receive appropriate preventive therapies, including lipid-lowering, antihypertensive, glucose-lowering, and antiplatelet therapy. ADT should preferably not be unnecessarily administered to prostate cancer patients with pre-existing cardiovascular disease, certainly not to those in whom the risk of prostate cancer-specific mortality is low. The physician should carefully weigh the potential benefits of ADT against the possible risks in individual patients with prostate cancer

  6. Radiation-induced secondary cancer in patients with uterine carcinoma

    International Nuclear Information System (INIS)

    In an effort to identify radiation-induced secondary cancer (RSC), data from 19,384 patients, which were treated for uterine carcinoma at seven institutions in Japan between 1960 and 1978, were statistically analyzed using a computer system. Treatment modalities included surgery alone (n = 6,655), radiation therapy and surgery (n = 4,310), and radiation therapy alone (n = 8,419). According to the criteria of Sakai et al., RSC was identified in 43 (0.3 %) of 12,729 patients receiving irradiation, including rectal cancer (14), leukemia (8), uterine corpus cancer (6), urinary bladder cancer (4), osteosarcoma or uterine sarcoma (3), sigmoid colon cancer or malignant fibrous histiocytoma (2), and ovarian cancer (one). When the risk of RSC for the rectum, the urinary bladder, and leukemia was analyzed using a person-years method, there was no statistically significant difference between the irradiated and non-irradiated patients. Therefore, three institutions were selected for further analysis with 2,686 patients (13,588 person-years), taking the effort and accuracy for follow-up of patients into account. The analysis showed statistically significant increase in RSC for the rectum and leukemia. It can thus be concluded that the accuracy for follow-up of patients is the most important factor in evaluating the incidence of RSC. (Namekawa, K.)

    Behavioral stress is known to promote tumor progression in experimental models, but the role of behavioral stress in cancer initiation is less clear. In this issue, Hassan et al. focus on the signaling and biological effects induced by stress hormones that lead to tumor cell evasion from apoptosis, resulting in prostate cancer progression.

    Cancer incidence was studied among 3072 first-degree relatives of 559 unselected ovarian cancer patients. Among cohort members there were 306 cancer cases. The overall cancer incidence was not increased: the standardised incidence ratio (SIR) in males was 0.9 (95% confidence interval 0.8-1.1) and in females 1.0 (0.8-1.1). The female relatives had a significantly increased risk for ovarian cancer (SIR 2.8, 1.8-4.2). The excess was attributable to sisters only (SIR 3.7, 2.3-5.7). The relative r...

    Patients affected by head and neck cancer are particularly at risk for nutritional depletion. The aim of this study was to evaluate the nutritional status of patients affected by head and neck cancer at diagnosis. All adult patients with head and neck cancer between January 2009 and December 2013 were included. The following data were recorded: demographics, tobacco and/or alcohol consumption, weight, height, the reference weight 6 months before the diagnosis, tumor site, tumor stage, and laboratory data. Then, Body mass index (BMI), and Buzby nutrition risk index (NRI) were calculated. Statistical analysis was used to search for associations among multiple variables. 122 men and 22 women were enrolled. As for reference BMI, 77 patients were overweight, whereas just 7 subjects were underweight. At diagnosis, 72 subjects were overweight according to BMI, whereas 52 patients were underweight. Instead, according to NRI, 96 patients were severely malnourished, 42 patients were moderately malnourished, whereas just 6 patients had a normal value of NRI. The assessment of nutrition by BMI excluded from a thorough consideration all overweight and obese patients with head and neck cancer. Instead, NRI correctly identified both undernourished and overweight/obese patients as "malnourished" subjects. PMID:25534287

    Full Text Available Estrogen involvement in breast cancer has been established; however, the association between breast cancer and thyroid diseases is controversial. Estrogen-like effects of thyroid hormone on breast cancer cell growth in culture have been reported. The objective of the present study was to determine the profile of thyroid hormones in breast cancer patients. Serum aliquots from 26 patients with breast cancer ranging in age from 30 to 85 years and age-matched normal controls (N = 22 were analyzed for free triiodothyronine (T3F, free thyroxine (T4F, thyroid-stimulating hormone (TSH, antiperoxidase antibody (TPO, and estradiol (E2. Estrogen receptor ß (ERß was determined in tumor tissues by immunohistochemistry. Thyroid disease incidence was higher in patients than in controls (58 vs 18%, P < 0.05. Subclinical hyperthyroidism was the most frequent disorder in patients (31%; hypothyroidism (8% and positive anti-TPO antibodies (19% were also found. Subclinical hypothyroidism was the only dysfunction (18% found in controls. Hyperthyroidism was associated with postmenopausal patients, as shown by significantly higher mean T3 and T4 values and lower TSH levels in this group of breast cancer patients than in controls. The majority of positive ERß tumors were clustered in the postmenopausal patients and all cases presenting subclinical hyperthyroidism in this subgroup concomitantly exhibited Erß-positive tumors. Subclinical hyperthyroidism was present in only one of 6 premenopausal patients. We show here that postmenopausal breast cancer patients have a significantly increased thyroid hormone/E2 ratio (P < 0.05, suggesting a possible tumor growth-promoting effect caused by this misbalance.

  12. Maxillofacial prosthetic rehalibilation of the oral cancer patient

    International Nuclear Information System (INIS)

    The victim of orofacial cancer is frequently subjected to severe morphological and functional disturbance: a condition which the maxillofacial prosthetist can do much to alleviate through the use of various prosthetic devices. The successful rehabilitation of these patients, however, is often compromised by the presence of psychosocial and other problems, the solution of which extends beyond the limits of a single clinical discipline. The modern approach to orofacial cancer, therefore, is organised within the context of interdisciplinary co-operation: each phase of patient management being planed and executed according to the co-ordinated efforts of the various members of a head and neck cancer team

ANP is a subcutaneous injection therapy of mountain ginseng pharmacopuncture (MGP along the acupoints on the spine (Hua-Tuo-Jia-Ji-Xue; 0.5 cun lateral to the lower border of the spinous processes of vertebrae to enhance the immune system and to balance autonomic nerve function. Methods: Patients with three different types of cancer (gastric cancer, lung cancer, colon cancer with distant metastases with cancer pain were treated with ANP. 1 mL of MGP was injected into the bilateral Hua-Tuo-Jia-Ji-Xue on the T1-L5 sites (total 12 ─ 20 mL injection of each patient’s dorsum by using the principle of symptom differentiation. During ANP treatment, the visual analogue scale (VAS for pain was used to assess their levels of cancer pain; also, the dosage and the frequency of analgesic use were measured. Results: The cancer pain levels of all three patients improved with treatment using ANP. The VAS scores of the three patients decreased as the treatment progressed. The dosage and the frequency of analgesics also gradually decreased during the treatment period. Significantly, no related adverse events were found. Conclusion: ANP has shown benefit in controlling cancer pain for the three different types of cancer investigated in this study and in reducing the dosage and the frequency of analgesics. ANP is expected to be beneficial for reducing cancer pain and, thus, to be a promising new treatment for cancer pain.

    The gap in cancer information seeking between high-socioeconomic status (SES) cancer patients and low-SES cancer patients deserves serious attention considering the importance of information and knowledge in cancer control. We thus explored the association of SES, as measured by education, with cancer patients’ overall cancer information seeking, and with seeking from each source (i.e., the Internet, mass media, medical sources, and non-medical interpersonal sources) and across two topic categories (i.e., treatment, quality of life). We then asked whether the effect of education on treatment information seeking is reduced among those who are particularly motivated to control treatment choices. We conducted a survey with breast, prostate, and colon cancer patients diagnosed in 2005 (N = 2,013), who were randomly drawn from the Pennsylvania Cancer Registry in the fall of 2006. We found that education was more strongly associated with Internet use than with the use of other sources regardless of topics. Also, when information was sought from mass media, education had a greater association with treatment information seeking than with quality-of-life information seeking. Preference for active participation in treatment decision making, however, did not moderate the effect of education on treatment information seeking. The implications of these findings for public health research and cancer patient education were discussed. PMID:22356137

    Ovarian cancer is the 5th most common cancer found in women in the UK. It is the leading cause of death from gynaecological cancer, and is the 4th most common cause of cancer death among UK women. Similar to the majority of other cancers, relative survival rates for ovarian cancer are improving, although 5-year mortality rates remain stubbornly low. The stage of the disease at diagnosis is the single most important determinant of ovarian cancer survival, as many patients first present with advanced disease. Treatment of ovarian cancer involves a combination of 'upfront' primary surgery followed by chemotherapy. Platinum/taxane-based chemotherapy is the recommended standard-of-care first-line chemotherapy, but the majority of patients will relapse with drug-resistant disease within 3-5 years. However, not all patients can continue with platinum combination therapies due to loss of activity or toxicity-related issues, including hypersensitivity, neurotoxicity, alopecia and ototoxicity. Therefore the choice of second-line chemotherapy must take into account factors such as platinum-free treatment interval (PFI); patient's performance status; current symptoms; history of and likely future toxicities while on chemotherapy; dosing schedule requirement; and cost of treatment. A consensus in 2010 established 4 distinct subgroups within the ROC patient population based on the PFI: (platinum sensitive <12 months, partially platinum sensitive 6-12 months, platinum resistant <6 months, and refractory disease ≤4 weeks). Within patients with platinum sensitive disease, those with partially platinum sensitive disease remain the most clinically challenging to manage effectively. Non-platinum based combination therapies, in particular trabectedin with pegylated liposomal doxorubicin (PLD), offers new options together with a significant survival advantage relative to PLD alone for these patients.

    Breast cancer is the most common cancer among women worldwide. Diagnosis and treatment in early stages increase cure chances. The temperature of cancerous tissue is generally higher than that of healthy surrounding tissues, making thermography an option to be considered in screening strategies of this cancer type. This paper proposes a hybrid methodology for analyzing dynamic infrared thermography in order to indicate patients with risk of breast cancer, using unsupervised and supervised machine learning techniques, which characterizes the methodology as hybrid. The dynamic infrared thermography monitors or quantitatively measures temperature changes on the examined surface, after a thermal stress. In the dynamic infrared thermography execution, a sequence of breast thermograms is generated. In the proposed methodology, this sequence is processed and analyzed by several techniques. First, the region of the breasts is segmented and the thermograms of the sequence are registered. Then, temperature time series are built and the k-means algorithm is applied on these series using various values of k. Clustering formed by k-means algorithm, for each k value, is evaluated using clustering validation indices, generating values treated as features in the classification model construction step. A data mining tool was used to solve the combined algorithm selection and hyperparameter optimization (CASH) problem in classification tasks. Besides the classification algorithm recommended by the data mining tool, classifiers based on Bayesian networks, neural networks, decision rules and decision tree were executed on the data set used for evaluation. Test results support that the proposed analysis methodology is able to indicate patients with breast cancer. Among 39 tested classification algorithms, K-Star and Bayes Net presented 100% classification accuracy. Furthermore, among the Bayes Net, multi-layer perceptron, decision table and random forest classification algorithms, an

    This study assessed anxiety/depression and stress response symptoms in adult cancer patients (n = 117), spouses (n = 76), and their children (n = 110, ages 6 to 30 years old) near the patients' diagnoses to identify family members at risk for psychological maladjustment. Patients' and family members' distress was related to appraisals of the seriousness and stressfulness of the cancer but not related to objective characteristics of the disease. Patients and spouses did not differ in anxiety/depression or in stress-response symptoms. Both stress-response and anxiety/depression symptoms differed in children as a function of age, sex of child, and sex of patient. Adolescent girls whose mothers had cancer were the most significantly distressed. Implications for understanding the impact of cancer on the family are highlighted. PMID:7889905

    Due to the increased number of cancer patients and the progress in cancer treatment, there are more cases with cancer-related lymphedema. Lymphedema treatment became part of oncological patients' care. Basic therapy for lymphedema is the complex decongestive therapy, which should be embedded into the patient's comprehensive medical care and should always be determined individually. Results of therapy are influenced by the experience of the doctor and the physiotherapist in lymphedema care, patient's complience, tumor behavior and the accompanying diseases. Lymphedema is a chronic disease, requires lifelong follow-up and treatment. For prevention and better care, it would be important to inform patients about lymphedema risk and appropriate life-style (e.g. weight control) preoperatively and during oncological follow-up. Early diagnosis is important. Lymphedema treatment should be integrated into palliative programmes. If therapy is started in time, complications may be avoided, healthcare costs may be reduced and better quality of life may be achieved. PMID:26996895

    Full Text Available Context Capecitabine, an oral drug, is as effective as traditional chemotherapy drugs. Objectives To investigate the adhesion to treatment with oral capecitabine in breast and colorectal cancer, and to determine any correlation with changes in patient’s quality of life. Methods Patients with colorectal cancer or breast cancer using capecitabine were included. The patients were asked to bring any medication left at the time of scheduled visits. The QLQ-C30 questionnaire was applied at the first visit and 8-12 weeks after treatment. Results Thirty patients were evaluated. Adherence was 88.3% for metastatic colon cancer, 90.4% for non-metastatic colon cancer, 94.3% for rectal cancer and 96.2% for metastatic breast cancer. No strong correlation between adherence and European Organisation for Research and Treatment of Cancer QLQ-C30 functional or symptom scale rates had been found. There was no statistically significant correlation between compliance and the functional and symptom scales of the questionnaire before and after chemotherapy, with the exception of dyspnea. Conclusions Although no absolute adherence to oral capecitabine treatment had been observed, the level of adherence was good. Health professionals therefore need a greater focus in the monitoring the involvement of patients with oral treatment regimens. Patients with lesser degrees of dyspnea had greater compliance.

    Children with cancer face both physical and psychosocial challenges. However, there is not enough empirical evidence in Taiwan regarding how they and their families cope with their illness. The purpose of the present study was to explore the psychosocial impact of cancer on target children and their families as well as the degree of depression experienced by these children. Twenty-four pediatric cancer patients, aged 8 through 17 years, completed the Chinese version of Children Depression Inventory (CDI). Both these patients and 18 parents completed questionnaires about their psychosocial adjustment since the diagnosis of cancer. The results showed: (i) patients did not perceive significant changes in their psychosocial adjustment, whereas parents indicated significantly lower mood of patients and a slight decrease in the number of friends; (ii) both parents and siblings showed positive adjustment; and (iii) there was neither significant difference on the CDI scores between the pediatric cancer patients and a normative group, nor significant relationships between patients' CDI scores and demographic characteristics of both patients and their parents, parenting attitudes, as well as variables related to the illness. Lastly, the results are discussed in terms of issues of methodology and instruments. Possible direction for further investigations is suggested. PMID:12519458

    Older adults with mild cognitive impairment (MCI) manifest impaired explicit memory. However, studies on implicit memory such as repetition effects in persons with MCI have been limited. In the present study, 17 MCI patients and 16 healthy normal controls (NC) completed a modified delayed-match-to-sample task while undergoing functional magnetic resonance imaging. We aim to examine the neural basis of repetition; specifically, to elucidate whether and how repetition-related brain responses are altered in participants with MCI. When repeatedly rejecting distracters, both NC and MCI showed similar behavioral repetition effects; however, in both whole-brain and region-of-interest analyses of functional data, persons with MCI showed reduced repetition-driven suppression in the middle occipital and middle frontal gyrus. Further, individual difference analysis found that activation in the left middle occipital gyrus was positively correlated with rejecting reaction time and negatively correlated with accuracy rate, suggesting a predictor of repetition behavioral performance. These findings provide new evidence to support the view that neural mechanisms of repetition effect are altered in MCI who manifests compensatory repetition-related brain activities along with their neuropathology.

    Hypercalcemia of malignancy (HCM) is a serious metabolic complication whose population-based prevalence has not been quantified. Rates of HCM differ by tumor type, with highest rates reported in multiple myeloma and lowest among colorectal and prostate cancer patients. This analysis estimates HCM prevalence in the US. This retrospective study used the Oncology Services Comprehensive Electronic Records (OSCER) warehouse of electronic health records (EHR) including laboratory values from 569000 patients treated at 565 oncology outpatient sites. OSCER data were projected to the national level by linking EHR to claims data. Cancer patients included were ≥18 years, and had serum calcium (Ca) and albumin (for corrected serum Ca [CSC]) records. Period prevalence was estimated by HCM CTCAE grade, tumor type, and year (2009-2013). Estimates were adjusted to capture patients diagnosed with HCM outside oncology practices based on a subset of patients linkable to office and hospital data. The analysis included 68023 (2009) to 121482 (2013) cancer patients. In 2013, patients with HCM had a median of six Ca tests, 69.7% had chemotherapy, and 34% received bone modifying agents. HCM rates were highest for multiple myeloma patients (7.5% [2012]-10.2% [2010]), lowest for prostate cancer (1.4% [2012]-2.1% [2011]).The estimated adjusted annual prevalence of HCM from 2009 to 2013 was 95441, 96281, 89797, 70158, and 71744, respectively. HCM affected 2.0-2.8% of all cancer patients. EHR data from oncology clinics were critical for this study because these data contain results from laboratory studies (i.e., serum calcium values) that are routinely ordered in that setting. We estimated that the prevalence of HCM in the US in 2013 is 71744, affecting approximately 2% of cancer patients overall. This percentage differs by tumor type and appears to have decreased over the five-year study period. PMID:27263488

    Full Text Available The etiology and pathogenesis of male breast cancer (MBC are poorly known. This is due to the fact that the disease is rare, and large-scale genetic epidemiologic studies have been difficult to carry out. Here, we studied the frequency of eight recurrent Finnish BRCA2 founder mutations in a large cohort of 154 MBC patients (65% diagnosed in Finland from 1967 to 1996. Founder mutations were detected in 10 patients (6.5%, eight of whom carried the 9346(-2 A>G mutation. Two novel mutations (4075 delGT and 5808 del5 were discovered in a screening of the entire BRCA2 coding region in 34 samples. However, these mutations were not found in the rest of the 120 patients studied. Patients with positive family history of breast and/or ovarian cancer were often BRCA2 mutation carriers (44%, whereas those with no family history showed a low frequency of involvement (3.6%; P < .0001. Finally, we found only one Finnish MBC patient with 999 dell, the most common founder mutation in Finnish female breast cancer (FBC patients, and one that explains most of the hereditary FBC and MBC cases in Iceland. The variation in BRCA2 mutation spectrum between Finnish MBC patients and FBC patients in Finland and breast cancer patients in Iceland suggests that modifying genetic and environmental factors may significantly influence the penetrance of MBC and FBC in individuals carrying germline BRCA2 mutations in some populations.

    Full Text Available OBJECTIVE: Patient chances for cure and palliation for a variety of malignancies may be greatly affected by the care provided by a treating hospital. We sought to determine the effect of volume and teaching status on patient outcomes for five gynecologic malignancies: endometrial, cervical, ovarian and vulvar carcinoma and uterine sarcoma. METHODS: The Florida Cancer Data System dataset was queried for all patients undergoing treatment for gynecologic cancers from 1990-2000. RESULTS: Overall, 48,981 patients with gynecologic malignancies were identified. Endometrial tumors were the most common, representing 43.2% of the entire cohort, followed by ovarian cancer (30.9%, cervical cancer (20.8%, vulvar cancer (4.6%, and uterine sarcoma (0.5%. By univariate analysis, although patients treated at high volume centers (HVC were significantly younger, they benefited from an improved short-term (30-day and/or 90-day survival for cervical, ovarian and endometrial cancers. Multivariate analysis (MVA, however, failed to demonstrate significant survival benefit for gynecologic cancer patients treated at teaching facilities (TF or HVC. Significant prognostic factors at presentation by MVA were age over 65 (HR = 2.6, p<0.01, African-American race (HR = 1.36, p<0.01, and advanced stage (regional HR = 2.08, p<0.01; advanced HR = 3.82, p<0.01, respectively. Surgery and use of chemotherapy were each significantly associated with improved survival. CONCLUSION: No difference in patient survival was observed for any gynecologic malignancy based upon treating hospital teaching or volume status. Although instances of improved outcomes may occur, overall further regionalization would not appear to significantly improve patient survival.

    Iron deficiency and iron deficiency-associated anemia are common complications in cancer patients. Most iron deficient cancer patients present with functional iron deficiency (FID), a status with adequate storage iron, but insufficient iron supply for erythroblasts and other iron dependent tissues. FID is the consequence of the cancer-associated cytokine release, while in absolute iron deficiency iron stores are depleted resulting in similar but often more severe symptoms of insufficient iron supply. Here we present a short review on the epidemiology, pathophysiology, diagnosis, clinical symptoms, and treatment of iron deficiency in cancer patients. Special emphasis is given to intravenous iron supplementation and on the benefits and limitations of different formulations. Based on these considerations and recommendations from current international guidelines we developed recommendations for clinical practice and classified the level of evidence and grade of recommendation according to the principles of evidence-based medicine.

We conducted a retrospective analysis in patients treated for advanced cervical cancer in order to investigate patient characteristics and prognosis of older patients.Methods: Medical records were collected of 159 patients with cervical cancer who had been treated with radiotherapy or combined radiotherapy and chemotherapy from January 2007 to January 2009. The patients were divided into two age groups: (1 patients ≥65 years old, and (2 patients 0.05. Seventy-six patients had human papillomavirus (HPV at diagnosis (twelve women ≥65 years, 64 women ≤65 years; P = 0.000. Forty-two women tested positive for HPV 16, while 32 women tested positive for HPV 18 respectively. Pelvic and/or paraaortic lymph-node metastasis was found in 25 patients (eight in group 1, 17 in group 2; P = 0.960 on computed tomography scan. Of the 159 patients analyzed, sixteen patients (16/52 in group 1 received concurrent chemotherapy, while 96 (96/107 in group 2 completed that treatment.Conclusions: Cervical cancer has the same prognosis in old and young women. Age may not be an independent increased risk of death in women with cervical cancer, and the age-group is at lower risk for virulent HPV strands (HPV 16/18 compared to younger patients. Treatment recommendations were implemented less often for older patients. Radiotherapy remained the most common treatment chosen for elderly patients. This confirms that there is a stronger need to pay attention to the elderly patient.Keywords: cervical cancer, older

  8. Chronic fatigue in cancer patients treated with radiotherapy

    International Nuclear Information System (INIS)

    Fatigue is one of the most prevalent and profound symptoms related to both malignancy and anti-neoplastic treatment. It is being reported in 60% to 80% of cancer patients. We review the correlation between the cancer-related fatigue syndrome and radiotherapy. In patients undergoing radiotherapy, fatigue is often cumulative and may reach its peak during the last weeks of treatment. The presence of fatigue prior to therapy initiation is the most important predictive factor of the occurrence of radiotherapy-related cancer fatigue syndrome. Occasionally, fatigue persists for a prolonged period of months and even years beyond radiotherapy. Anemia may be one of major causative factors responsible for the development of the cancer-related fatigue syndrome. Fatigue has an enormous physical, mental, emotional, and economic impact on cancer patients, their families and care-providers. The treatment of radiation-related fatigue remains unknown. The initial approach should cover efforts aimed at the correction of potential etiologies, especially anemia. Education concerning fatigue greatly benefits some patients. It seems that exercise may be beneficial in relieving fatigue, bearing in mind that the exercise program for cancer patients should be initiated gradually and significantly individualized. (author)

    Purpose Thrombocytosis is known to be a poor prognostic factor in several types of solid tumors. The prognostic role of preoperative thrombocytosis in colorectal cancer remains limited. The aim of this study is to investigate the prognostic role of preoperative thrombocytosis in stage II colorectal cancer. Methods Two hundred eighty-four patients with stage II colorectal cancer who underwent surgical resection between December 2003 and December 2009 were retrospectively reviewed. Thrombocytosis was defined as platelet > 450 × 109/L. We compared patients with thrombocytosis and those without thrombocytosis in terms of survival. Results The 5-year disease-free survival (DFS) rates were lower in patients with thrombocytosis compared to those without thrombocytosis in stage II colorectal cancer (73.3% vs. 89.6%, P = 0.021). Cox multivariate analysis demonstrated that thrombocytosis (hazard ratio, 2.945; 95% confidence interval, 1.127–7.697; P = 0.028) was independently associated with DFS in patients with stage II colorectal cancer. Conclusion This study showed that thrombocytosis is a prognostic factor predicting DFS in stage II colorectal cancer patients. PMID:27274508

    Cognitive functioning is impaired in patients with schizophrenia, leading to significant disabilities in everyday functioning. Its improvement is an important treatment target. Neurofeedback (NF) seems a promising method to address the neural dysfunctions underlying those cognitive impairments. The anterior cingulate cortex (ACC), a central hub for cognitive processing, is one of the brain regions known to be dysfunctional in schizophrenia. Here we conducted NF training based on real-time functional magnetic resonance imaging (fMRI) in patients with schizophrenia to enable them to control their ACC activity. Training was performed over 3 days in a group of 11 patients with schizophrenia and 11 healthy controls. Social feedback was provided in accordance with the evoked activity in the selected region of interest (ROI). Neural and cognitive strategies were examined off-line. Both groups learned to control the activity of their ACC but used different neural strategies: patients activated the dorsal and healthy controls the rostral subdivision. Patients mainly used imagination of music to elicit activity and the control group imagination of sports. In a stepwise regression analysis, the difference in neural control did not result from the differences in cognitive strategies but from diagnosis alone. Based on social reinforcers, patients with schizophrenia can learn to regulate localized brain activity. However, cognitive strategies and neural network location differ from healthy controls. These data emphasize that for therapeutic interventions in patients with schizophrenia compensatory strategies may emerge. Specific cognitive skills or specific dysfunctional networks should be addressed to train impaired skills. Social NF based on fMRI may be one method to accomplish precise learning targets.

    Full Text Available Abstract Background Individuals heterozygous for germline ATM mutations have been reported to have an increased risk for breast cancer but the role for ATM genetic variants for breast cancer risk has remained unclear. Recently, a common ATM variant, ATMivs38 -8T>C in cis with the ATMex39 5557G>A (D1853N variant, was suggested to associate with bilateral breast cancer among familial breast cancer patients from Northern Finland. We have here evaluated the 5557G>A and ivs38-8T>C variants in an extensive case-control association analysis. We also aimed to investigate whether there are other ATM mutations or variants contributing to breast cancer risk in our population. Methods Two common ATM variants, 5557G>A and ivs38-8T>C, previously suggested to associate with bilateral breast cancer, were genotyped in an extensive set of 786 familial and 884 unselected breast cancer cases as well as 708 healthy controls. We also screened the entire coding region and exon-intron boundaries of the ATM gene in 47 familial breast cancer patients and constructed haplotypes of the patients. The identified variants were also evaluated for increased breast cancer risk among additional breast cancer cases and controls. Results Neither of the two common variants, 5557G>A and ivs38-8T>C, nor any haplotype containing them, was significantly associated with breast cancer risk, bilateral breast cancer or multiple primary cancers in any of the patient groups or subgoups. Three rare missense alterations and one intronic change were each found in only one patient of over 250 familial patients studied and not among controls. The fourth missense alteration studied further was found with closely similar frequencies in over 600 familial cases and controls. Conclusion Altogether, our results suggest very minor effect, if any, of ATM genetic variants on familial breast cancer in Southern Finland. Our results do not support association of the 5557G>A or ivs38-8T>C variant with

    Patient navigation is an internationally utilized, culturally grounded, and multifaceted strategy to optimize patients' interface with the health-care team and system. The DuPage County Patient Navigation Collaborative (DPNC) is a campus-community partnership designed to improve access to care among uninsured breast and cervical cancer patients in DuPage County, IL. Importantly, the DPNC connects community-based social service delivery with the patient-centered medical home to achieve a community-nested patient-centered medical home model for cancer care. While the patient navigator experience has been qualitatively documented, the literature pertaining to patient navigation has largely focused on efficacy outcomes and program cost effectiveness. Here, we uniquely highlight stories of women enrolled in the DPNC, told from the perspective of patient navigators, to shed light on the myriad barriers that DPNC patients faced and document the strategies DPNC patient navigators implemented.

  19. Breast cancer in patients previously irradiated for Hodgkin disease

    International Nuclear Information System (INIS)

    Breast cancer (BC) developing patients cured of Hodgkin disease (HD) has been only anecdotally reported. The authors identified 21 patients at Memorial Sloan Kettering Cancer Center who developed a total of 22 BCs since 1969 and had a history of cured HD. The median time interval between HD and BC was 14 years. All patients had modified or radical mastectomy with no complications. There was no unusual distribution of the lesions in the breasts. The course of BC did not differ from what is to be expected per stage of BC and length of follow-up. All patients had radiation treatment for their HD. Seven patients were also treated with chemotherapy. The radiation dose delivered was 2,000-3,000 cGy in six patients and 3,600-4,000 cGy in 12 patients. Nine patients were treated to the mantle field and nine to multiple components of a mantle-like field. The data show that BC developing in cured HD patients did not have unique characteristics. They did not identify an increased risk to develop BC attributable to technique, dose, or energy used in the radiation of these patients. It remains unclear whether HD and/or its treatment with radiation predisposes the patient to develop breast cancer

    Cancer and neurocognitive disorders, such as dementia and delirium, are common and serious diseases in the elderly that are accompanied by high degree of morbidity and mortality. Furthermore, evidence supports the under-diagnosis of both dementia and delirium in older adults. Complex questions exist regarding the interaction of dementia and delirium with cancer, beginning with guidelines on how best measure disease severity, the optimal screening test for either disorder, the appropriate level of intervention in the setting of abnormal findings, and strategies aimed at preventing the development or progression of either process. Ethical concerns emerge in the research setting, pertaining to the detection of cognitive dysfunction in participants, validity of consent, disclosure of abnormal results if screening is pursued, and recommended level of intervention by investigators. Furthermore, understanding the ways in which comorbid cognitive dysfunction and cancer impact both cancer and non-cancer-related outcomes is essential in guiding treatment decisions. In the following article, we will discuss what is presently known of the interactions of pre-existing cognitive impairment and delirium with cancer. We will also discuss identified deficits in our knowledge base, and propose ways in which innovative research may address these gaps. PMID:27282296

    Full Text Available The most frequent ultimate cause of death is myocardial arrest. In many cases this is due to myocardial hypoxia, generally arising from failure of the coronary macro- and microcirculation to deliver enough oxygenated red cells to the cardiomyocytes. The principle reason for this is occlusive thrombosis, either by isolated circulating thrombi, or by rupture of upstream plaque. However, an additionally serious pathology causing potentially fatal stress to the heart is extra-cardiac disease, such as pulmonary hypertension. A primary cause of the latter is pulmonary embolus, considered to be a venous thromboembolism. Whilst the thrombotic scenario has for decades been the dominating paradigm in cardiovascular disease, these issues have, until recently, been infrequently considered in cancer. However, there is now a developing view that cancer is also a thrombotic disease, and notably a disease predominantly of the venous circulation, manifesting as deep vein thrombosis and pulmonary embolism. Indeed, for many, a venous thromboembolism is one of the first symptoms of a developing cancer. Furthermore, many of the standard chemotherapies in cancer are prothrombotic. Accordingly, thromboprophylaxis in cancer with heparins or oral anticoagulation (such as Warfarin, especially in high risk groups (such as those who are immobile and on high dose chemotherapy, may be an important therapy. The objective of this communication is to summarise current views on the epidemiology and pathophysiology of arterial and venous thrombosis in cancer.

    Currently, there is a lack of evidence evaluating the psychological impact of cancer-related risk perception and worry in individuals at high risk for gastric cancer. We examined the relationships between perceived risk, cancer worry and screening behaviors among first-degree relatives (FDRs) of patients with familial gastric cancer. FDRs of patients diagnosed with familial gastric cancer with a non-informative genetic analysis were identified and contacted. Participants completed a telephone interview that assessed socio-demographic information, cancer risk perception, cancer worry, impact of worry on daily functioning, and screening behaviors. Twenty-five FDRs completed the telephone interview. Participants reported high levels of comparative and absolute cancer risk perception, with an average perceived lifetime risk of 54 %. On the other hand, cancer-related worry scores were low, with a significant minority (12 %) experiencing high levels of worry. Study participants exhibited high levels of confidence (median = 70 %) in the effectiveness of screening at detecting a curable cancer. Participants that had undergone screening in the past showed significantly lower levels of cancer-related worry compared to those that had never undergone screening. In conclusion, individuals at high-risk for gastric cancer perceived a very high personal risk of cancer, but reported low levels of cancer worry. This paradoxical result may be attributed to participants' high levels of confidence in the effectiveness of screening. These findings highlight the importance for clinicians to discuss realistic risk appraisals and expectations towards screening with unaffected members of families at risk for gastric cancer, in an effort to help mitigate anxiety and help with coping.

    The present work aims to obtain groups of patients with similar profiles of p24 antigen concentration and of CD4+ cell counts. These two markers were chosen because their evaluation represents a significant step in the clinical follow up of HIV-1 infected subjects. The classifications were obtained by a Kohonen neural net trained in three ways: with p24 antigen profiles only, with CD4+ cell count profiles only and with both sets of profiles. The results show that the clustering fashion of the two parameters closely resembles the clustering fashion of CD4+ only rather than the one of p24Ag, both with reference to cluster formation and with reference to distance among clusters.

    2014-01-01

    Cancer-related fatigue is a common yet underappreciated problem with a significant impact on functional ability and quality of life. Practice guidelines mandate that all cancer patients and survivors be screened for cancer-related fatigue (CRF) at regular intervals. Comorbidities that could contribute to fatigue should be treated, and patients with moderate to severe fatigue should undergo a comprehensive evaluation. Nonpharmacologic interventions are important tools to combat CRF and should be incorporated into routine practice. Physical activity, educational interventions, and cognitive-behavioral therapy have the most supportive data and can be recommended to patients with confidence. From a practical standpoint, general education on CRF is something that most care providers can readily offer patients as part of routine care. Other interventions that appear promising but are as yet lacking convincing evidence include mindfulness-based stress reduction, yoga, and acupuncture. Reiki, Qigong, hypnosis, and music therapy may be worthy of further investigation. PMID:25299140

  12. Patient-specific data fusion defines prognostic cancer subtypes.

    Directory of Open Access Journals (Sweden)

    Yinyin Yuan

    2011-10-01

    Full Text Available Different data types can offer complementary perspectives on the same biological phenomenon. In cancer studies, for example, data on copy number alterations indicate losses and amplifications of genomic regions in tumours, while transcriptomic data point to the impact of genomic and environmental events on the internal wiring of the cell. Fusing different data provides a more comprehensive model of the cancer cell than that offered by any single type. However, biological signals in different patients exhibit diverse degrees of concordance due to cancer heterogeneity and inherent noise in the measurements. This is a particularly important issue in cancer subtype discovery, where personalised strategies to guide therapy are of vital importance. We present a nonparametric Bayesian model for discovering prognostic cancer subtypes by integrating gene expression and copy number variation data. Our model is constructed from a hierarchy of Dirichlet Processes and addresses three key challenges in data fusion: (i To separate concordant from discordant signals, (ii to select informative features, (iii to estimate the number of disease subtypes. Concordance of signals is assessed individually for each patient, giving us an additional level of insight into the underlying disease structure. We exemplify the power of our model in prostate cancer and breast cancer and show that it outperforms competing methods. In the prostate cancer data, we identify an entirely new subtype with extremely poor survival outcome and show how other analyses fail to detect it. In the breast cancer data, we find subtypes with superior prognostic value by using the concordant results. These discoveries were crucially dependent on our model's ability to distinguish concordant and discordant signals within each patient sample, and would otherwise have been missed. We therefore demonstrate the importance of taking a patient-specific approach, using highly-flexible nonparametric

    Individuals with borderline personality disorder (BPD) are characterized by emotional instability, impaired emotion regulation and unresolved attachment patterns associated with abusive childhood experiences. We investigated the neural response during the activation of the attachment system in BPD patients compared to healthy controls using functional magnetic resonance imaging (fMRI). Eleven female patients with BPD without posttraumatic stress disorder (PTSD) and 17 healthy female controls matched for age and education were telling stories in the scanner in response to the Adult Attachment Projective Picture System (AAP), an eight-picture set assessment of adult attachment. The picture set includes theoretically-derived attachment scenes, such as separation, death, threat and potential abuse. The picture presentation order is designed to gradually increase the activation of the attachment system. Each picture stimulus was presented for 2 min. Analyses examine group differences in attachment classifications and neural activation patterns over the course of the task. Unresolved attachment was associated with increasing amygdala activation over the course of the attachment task in patients as well as controls. Unresolved controls, but not patients, showed activation in the right dorsolateral prefrontal cortex (DLPFC) and the rostral cingulate zone (RCZ). We interpret this as a neural signature of BPD patients’ inability to exert top-down control under conditions of attachment distress. These findings point to possible neural mechanisms for underlying affective dysregulation in BPD in the context of attachment trauma and fear. PMID:27531977

    Full Text Available For hospitals’ admission management, the ability to predict length of stay (LOS as early as in the preadmission stage might be helpful to monitor the quality of inpatient care. This study is to develop artificial neural network (ANN models to predict LOS for inpatients with one of the three primary diagnoses: coronary atherosclerosis (CAS, heart failure (HF, and acute myocardial infarction (AMI in a cardiovascular unit in a Christian hospital in Taipei, Taiwan. A total of 2,377 cardiology patients discharged between October 1, 2010, and December 31, 2011, were analyzed. Using ANN or linear regression model was able to predict correctly for 88.07% to 89.95% CAS patients at the predischarge stage and for 88.31% to 91.53% at the preadmission stage. For AMI or HF patients, the accuracy ranged from 64.12% to 66.78% at the predischarge stage and 63.69% to 67.47% at the preadmission stage when a tolerance of 2 days was allowed.

    Full Text Available The electromyogram recorded from the diaphragm (EMGdi and parasternal intercostal muscle using surface electrodes (sEMGpara provides a measure of neural respiratory drive (NRD, the magnitude of which reflects lung disease severity in stable cystic fibrosis. The aim of this study was to explore perception of NRD and breathlessness in both healthy individuals and patients with cystic fibrosis. Given chronic respiratory loading and increased NRD in cystic fibrosis, often in the absence of breathlessness at rest, we hypothesised that patients with cystic fibrosis would be able to tolerate higher levels of NRD for a given level of breathlessness compared to healthy individuals during exercise. 15 cystic fibrosis patients (mean forced expiratory volume in 1 s (FEV1 53.5% predicted and 15 age-matched, healthy controls were studied. Spirometry was measured in all subjects and lung volumes measured in the cystic fibrosis patients. EMGdi and sEMGpara were recorded at rest and during incremental cycle exercise to exhaustion and expressed as a percentage of maximum (% max obtained from maximum respiratory manoeuvres. Borg breathlessness scores were recorded at rest and during each minute of exercise. EMGdi % max and sEMGpara % max and associated Borg breathlessness scores differed significantly between healthy subjects and cystic fibrosis patients at rest and during exercise. The relationship between EMGdi % max and sEMGpara % max and Borg score was shifted to the right in the cystic fibrosis patients, such that at comparable levels of EMGdi % max and sEMGpara % max the cystic fibrosis patients reported significantly lower Borg breathlessness scores compared to the healthy individuals. At Borg score 1 (clinically significant increase in breathlessness from baseline corresponding levels of EMGdi % max (20.2±12% versus 32.15±15%, p=0.02 and sEMGpara % max (18.9±8% versus 29.2±15%, p=0.04 were lower in the healthy individuals compared to the cystic

Materials and Methods: Ninety breast cancer patients and equal number of age-matched healthy females were recruited into the study by consecutive sampling over a period of 6 months for this case control study. Serum 25(OH2D levels and CT bone mineral density was done. Results: The mean age was 46±1.5 years. Age, marital status, menopausal, residential area, parda observing status, and body mass index were similar in distribution among cases and controls. The mean serum vitamin D level in the breast cancer patients was 9.3 ng/ml and in the control group was 14.9 ng/ml (P value <0.001. Vitamin D deficiency was seen in 95.6% (86 breast cancer patients and in 77% (69 of the control group (P value <0.001. Among the breast cancer patients the tumor characteristics (histology, grade, stage, and receptor status did not show any significant associations with serum levels of vitamin D. Premenopausal breast cancer females had a mean serum vitamin D level of 10.5 ng/ml and postmenopausal females had a mean value of 13.5 ng/ml (P value 0.015. Low BMD did not correlate significantly with vitamin D deficiency (P value 0.787. Conclusion: Invariably almost all patients with breast cancer were vitamin D deficient. Tumor characteristics did not show any significant associations with serum levels of vitamin D. Bone mineral density did not correlate significantly with vitamin D deficiency.

    Integrative oncology uses non-pharmacological adjuncts to mainstream care to manage physical, emotional, and psychological symptoms experienced by cancer survivors. Depression, anxiety, fatigue and pain are among the common, often burdensome symptoms that can occur in clusters, deplete patient morale, interfere with treatment plans, and hamper recovery. Patients already seek various modalities on their own to address a broad range of problems. Legitimate complementary therapies offered at major cancer institutions improve quality of life, speed recovery, and optimize patient support. They also augment the benefits of psychiatric interventions, due to their ability to increase self-awareness and improve physical and psychological conditioning. Further, these integrated therapies provide lifelong tools and develop skills that patients use well after treatment to develop self-care regimens. The active referral of patients to integrative therapies achieves three important objectives: complementary care is received from therapists experienced in working with cancer patients, visits become part of the medical record, allowing treatment teams to guide individuals in maximizing benefit, and patients are diverted from useless or harmful 'alternatives.' We review the reciprocal physical and psychiatric benefits of exercise, mind-body practices, massage, acupuncture, and music therapy for cancer survivors, and suggest how their use can augment mainstream psychiatric interventions.

  1. Levels of estrogen, carcinoembryonic antigen and cancer antigen of breast in breast cancer patients

    International Nuclear Information System (INIS)

    This study was conducted during the period from february 2004 to July 2004; with the objective of measuring the levels of estrogen (E2), carcinoembryonic antigen (CEA) and cancer antigen of breast (CA-15.3) so as to facilitate the early diagnosis of breast cancer and determine the involvement of these parameters as risk factors for breast cancer. Ninety blood samples were collected from Sudanese females, divided into two groups; control group and patient groups. The patients group was sixty Sudanese females visiting the Radio Isotope Center, Khartoum (RICK) and they were confirmed as breast cancer patient by histopathology. The levels of the above mentioned parameters were determined by using radioimmunoassay technique. The results showed that, no significant (p=0.05) difference between the levels of the estrogen in patients compared to the control, on the other hand there was non significant (p>0.05) elevation in CEA levels in the patients with breast cancer compared to the control. The level of CA15.3 was significantly (p<0.0001) higher in the breast cancer patients compared to the control.(Author)

    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.

    Several animal studies have demonstrated that pain is modulated by spinal mechanisms involving prostaglandins and that acetylsalicylic acid (ASA) administered intrathecally has an analgesic effect. We report our experience of this treatment in 60 patients with proven and advanced cancer. An isobaric solution of lysine acetylsalicylate was administered by lumbar puncture in doses ranging from 120 to 720 mg of ASA. The results were evaluated using the habitual criteria: scoring system, behaviour, consumption of analgesic drugs. In this trial the method proved astonishingly effective (78% of the cases). Analgesia was strong, almost immediate and without influence on motricity. No thermic or neurovegetative changes were noted. The effect of one injection lasted from 3 weeks to 1 month on average; it was reproduced and often more prolonged after a repeat injection. Pain associated with bone metastases seems to constitute the best indication, notably in breast and lung cancer and in myeloma. Visceral (pancreas) or neural pain requires higher doses to respond. Failures (22%) were due to such factors as insufficient dosage at the very beginning of our experience or severe depressive syndrome. The perineal and sphincteral pain of rectal cancer often resists treatment. This simple, inexpensive and very effective method with no other complication than a frequent tendency to fatigue should rank among other analgesic measures in cancer. The lack of respiratory depression is a major advantage over catheter spinal opiate analgesia. We consider that its main indications are pain associated with osteolytic metastases of adenocarcinomas, and myelomas. Owing to the absence of formal toxicological data, its use must be limited to cancer pain and to patients with a life expectancy of less than 2 years. PMID:2957675

  6. Brachytherapy for elderly patients with stage II tongue cancer

    International Nuclear Information System (INIS)

    In treatment choices of stage II (T2N0M0) tongue cancer, brachytherapy is less invasive and superior in function preservation, therefore its role is more important in elderly patients. The aim of this study was to evaluate treatment results and morbidity of brachytherapy for elderly patients with stage II tongue cancer. Between 1980 and 2001, 198 patients with stage II tongue cancer were treated with brachytherapy at Hiroshima University Hospital. Patient ages ranged from 21 to 89 years old (median: 62 years old). Patients were divided into three groups as follows: 119 patients younger than 65 years old (Non-Elderly group), 53 patients between 65 and 75 years old (Junior Elderly group), and 26 patients 75 years or older (Senior Elderly group). Radiotherapy was performed in 101 patients with brachytherapy alone, and in 97 patients with brachytherapy and external radiotherapy. Chemotherapy was also performed in 77 patients. Follow-up period ranged from 4 to 243 months (median: 55 months). The 5-year local control rate was 85% in the Non-Elderly group, 85% in the Junior Elderly group and 81% in the Senior Elderly group. There was no significant difference among these groups. The 5-year cause-specific survival rate was 85%, 81% and 70% respectively. The Senior Elderly group showed poorer cause-specific survival rate than the other two groups (p=0.03). There was also a tendency of higher incidence of neck metastasis and low salvage rate by neck dissection in the Senior Elderly group. Although the Senior Elderly group showed poorer cause-specific survival rate, the local control rate was similar to those of the other two groups. Brachytherapy is an effective treatment option for elderly patients with stage II tongue cancer. (author)

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

  8. Prognostic stratification of colorectal cancer patients: current perspectives

    International Nuclear Information System (INIS)

    Tumor staging according to the American Joint Committee on Cancer/Union for International Cancer Control tumor, node, metastasis (TNM) system is currently regarded as the standard for staging of patients with colorectal cancer. This system provides the strongest prognostic information for patients with early stage disease and those with advanced disease. For patients with intermediate levels of disease, it is less able to predict disease outcome. Therefore, additional prognostic markers are needed to improve the management of affected patients. Ideal markers are readily assessable on hematoxylin and eosin-stained tumor slides, and in this way are easily applicable worldwide. This review summarizes the histological features of colorectal cancer that can be used for prognostic stratification. Specifically, we refer to the different histological variants of colorectal cancer that have been identified, each of these variants carrying distinct prognostic significance. Established markers of adverse outcomes are lymphatic and venous invasion, as well as perineural invasion, but underreporting still occurs in the routine setting. Tumor budding and tumor necrosis are recent advances that may help to identify patients at high risk for recurrence. The prognostic significance of the antitumor inflammatory response has been known for quite a long time, but a lack of standardization prevented its application in routine pathology. However, scales to assess intra- and peritumoral inflammation have recently emerged, and can be expected to strengthen the prognostic significance of the pathology report

  9. Comparison of logistic regression and neural models in predicting the outcome of biopsy in breast cancer from MRI findings

    International Nuclear Information System (INIS)

    Background: We designed an algorithmic model based on regression analysis and a non-algorithmic model based on the Artificial Neural Network. Materials and methods: The ability of these models was compared together in clinical application to differentiate malignant from benign breast tumors in a study group of 161 patient's records. Each patient's record consisted of 6 subjective features extracted from MRI appearance. These findings were enclosed as features extracted for an Artificial Neural Network as well as a logistic regression model to predict biopsy outcome. After both models had been trained perfectly on samples (n=100), the validation samples (n=61) were presented to the trained network as well as the established logistic regression models. Finally, the diagnostic performance of models were compared to the that of the radiologist in terms of sensitivity, specificity and accuracy, using receiver operating characteristic curve analysis. Results: The average out put of the Artificial Neural Network yielded a perfect sensitivity (98%) and high accuracy (90%) similar to that one of an expert radiologist (96% and 92%) while specificity was smaller than that (67%) verses 80%). The output of the logistic regression model using significant features showed improvement in specificity from 60% for the logistic regression model using all features to 93% for the reduced logistic regression model, keeping the accuracy around 90%. Conclusion: Results show that Artificial Neural Network and logistic regression model prove the relationship between extracted morphological features and biopsy results. Using statistically significant variables reduced logistic regression model outperformed of Artificial Neural Network with remarkable specificity while keeping high sensitivity is achieved

    Pituitary metastases are uncommon complications of systemic cancer and account for only 1% of pituitary lesions. Breast cancer is one of the most common tumors to metastasize to the pituitary gland. A multidisciplinary approach that calls for close collaboration among oncologists, neurosurgeons, radiologists, and endocrinologists is mandatory for diagnosis and treatment of pituitary metastasis. From 2002 through 2013, 6 patients with pituitary metastases were treated at Shizuoka Cancer Center Hospital. The patients' age at presentation ranged from 45 to 75 years(average 59 years). Five of 6 patients had symptoms: anterior pituitary insufficiency in 4, diabetes insipidus in 3, and visual deficits in 2 patients. Five patients had other metastases at the time of presentation. Local irradiation to the metastatic lesion was adopted in 4, and whole brain irradiation was in 2 patients. In all cases, local control was achieved after irradiation, however, the pituitary insufficiency did not recover. Two of 4 patients treated with local irradiation suffered from meningeal dissemination within 5 months after treatment, and died at 8 and 11 months after diagnosis of pituitary metastasis, respectively. The patients treated with whole brain irradiation had longer survival periods. Early diagnosis, endocrinological management, and radiation therapy improve the quality of life in patients suffering from pituitary metastasis. Whole brain irradiation may be favorable in order to prevent meningeal dissemination. PMID:27166841

    Clinical trials of late-stage breast cancer patients and late-stage melanoma patients treated by laser immunotherapy (LIT) have shown promising results. In a 2010 study of Li et al, eleven late-stage melanoma patients received LIT in one or multiple 6-week treatment cycles applied to a 200-cm2 treatment site, which usually contained multiple cutaneous metastases. Long-term, positive response was observed in six patients. All lesions in the treatment area of the patients responded to LIT, eight of which achieved complete local response (CLR). CLR was observed in the non-treatment site (regional) lesions in four patients. Five patients were still alive at the time of last follow-up. The probability of 12-month overall survival was 70%.2 In 2011, Li et al, treated ten late stage breast cancer patients with LIT.1 In 8 patients available for evaluation, the objective response rate was 62.5% and the clinical beneficial response rate was 75%.1 This review demonstrates that LIT is safe and well tolerated, so it can be easily applied on an outpatient basis and can be combined with other pharmaceutical modalities to improve the therapeutic response of metastatic cancers.

  13. Treatment outcomes of definitive chemoradiotherapy for patients with hypopharyngeal cancer

    International Nuclear Information System (INIS)

    We analyzed the efficacy of definitive chemoradiotherapy (CRT) for patients with hypopharyngeal cancer (HPC). Subjects comprised 97 patients who were treated with definitive CRT from 1990 to 2006. Sixty-one patients (62.9%) with resectable disease who aimed to preserve the larynx received induction chemotherapy (ICT), whereas 36 patients (37.1%) with resectable disease who refused an operation or who had unresectable disease received primary alternating CRT or concurrent CRT (non-ICT). The median dose to the primary lesion was 66 Gy. The median follow-up time was 77 months. The 5-year rates of overall survival (OS), progression-free survival (PFS), local control (LC), and laryngeal preservation were 68.7%, 57.5%, 79.1%, and 70.3%, respectively. The T-stage was a significant prognostic factor in terms of OS, PFS and LC in both univariate and multivariate analyses. The 5-year rates of PFS were 45.4% for the ICT group and 81.9% for the non-ICT group. The difference between these groups was significant with univariate analysis (P=0.006). Acute toxicity of Grade 3 to 4 was observed in 34 patients (35.1%). Grade 3 dysphagia occurred in 20 patients (20.6%). Twenty-nine (29.8%) of 44 patients with second primary cancer had esophageal cancer. Seventeen of 29 patients had manageable superficial esophageal cancer. The clinical efficacy of definitive CRT for HPC is thought to be promising in terms of not only organ preservation but also disease control. Second primary cancer may have a clinical impact on the outcome for HPC patients, and special care should be taken when screening at follow-up. (author)

    Full Text Available Background: No evidence-based guidelines or protocols to treat the infection-related symptoms in cancer patients with terminal stages have been established. Materials and Methods: We retrospectively analyzed all the patients with terminal stage cancer who died between April 2009 and March 2010. The patients' background, the prevalence of infection and clinical outcomes, pathogens isolated, antibiotics used, and whether blood cultures and some of examinations were performed or not were evaluated. Results: A total of 62 (44 males and 18 females patients were included in this study. The median age was 73 years (35-98 years. The most common cancer was that of the lung (n =59, 95.2%. A total of 32 patients were diagnosed with the following infections: Infection of respiratory tract in 27 (84.4%, of urinary tract in 4 (12.5%, and cholangitis in 1 (3.1%. Two cases (6.3% had pneumonia complicated with urinary tract infection. Blood cultures and antibiotic therapies were performed in 28 and 30 cases, respectively. Four (14.3% positive cultures were isolated from the blood obtained from 28 individual patients. As for clinical course, 3 (10% of them experienced improved symptoms after antibiotic therapy. Twenty-seven (90% patients were not confirmed as having any symptom improvement. Conclusions: Blood cultures and antibiotic therapy were limited, and might not be effective in terminally ill cancer patients with lung cancer. We suggest that administering an antibiotic therapy without performing a blood culture would be one of choices in those with respiratory tract infections if patients' life expectancy is short.

  15. Analysis of the individual radio sensitivity of breast cancer patients

    International Nuclear Information System (INIS)

    Individual radiosensitivity has a crucial impact on radiotherapy related side effects. A prediction of individual radiosensitivity could avoid these side effects. Our aim was to study a breast cancer collective for its variation of individual radiosensitivity. Peripheral blood samples were obtained from 129 individuals. 67 breast cancer patients and 62 healthy and age matched individuals were looked at and their individual radiosensitivity was estimated by a 3-color Fluorescence in situ hybridization approach. Blood samples were obtained (i) before starting adjuvant radiotherapy and were in vitro irradiated by 2 Gy; (ii) after 5 single doses of 1.8 Gy and after 72 h had elapsed. DNA of lymphocytes was probed with whole chromosome painting for chromosomes 1, 2 and 4. The rate of breaks per metaphase was analyzed and used as a predictor of individual radiosensitivity. Breast cancer patients were distinctly more radio-sensitive compared to healthy controls. Additionally the distribution of the cancer patients' radiosensitivity was broader. A subgroup of 9 rather radio-sensitive and 9 rather radio-resistant patients was identified. A subgroup of patients aged between 40 and 50 was distinctly more radio-sensitive than younger or older patients. The in vivo irradiation approach was not applicable to detect individual radiosensitivity. In the breast cancer collective a distinctly resistant and sensitive subgroup is identified, which could be subject for treatment adjustment. Especially in the range of age 40 to 50 patients have an increased radiosensitivity. An in vivo irradiation in a breast cancer collective is not suitable to estimate individual radiosensitivity due to a low deposed dose.

    Cancer burden in Malaysia is increasing. Although there have been improvements in cancer treatment, these new therapies may potentially cause an exponential increase in the cost of cancer treatment. Therefore, justification for the use of these treatments is mandated. Availability of local data will enable us to evaluate and compare the outcome of our patients. This will help to support our clinical decision making and local policy, improve access to treatment and improve the provision and delivery of oncology services in Malaysia. The National Cancer Patient Registry was proposed as a database for cancer patients who seek treatment in Malaysia. It will be a valuable tool to provide timely and robust data on the actual setting in oncology practice, safety and cost effectiveness of treatment and most importantly the outcome of these patients.

  8. Screening examinations for double cancer in patients with oral cancer. Usefulness of gastrointestinal endoscopy and positron emission tomography

    International Nuclear Information System (INIS)

    Many patients with oral cancer have double cancers, especially in the upper gastrointestinal tract. We studied synchronous double cancers in 138 patients with oral cancer who underwent gastrointestinal endscopy and 161 who underwent positron emission tomography (PET) preoperatively. Fifteen patients (10.9%) had cancer or precancerous lesions in the upper gastrointestinal tract on gastrointestinal endoscopy: 10 in the esophagus and 5 in the stomach. The histopathological diagnosis was severe epithelial dysplasia in 6 patients, carcinoma in situ in 4, and carcinoma in 5. These 15 lesions were asymptomatic and detected by gastrointestinal endscopy for the first time. Patients with severe epithelial dysplasia were observed, and those with carcinoma or carcinoma in situ underwent radical therapy. All of these gastrointestinal lesions were treated successfully, without any recurrence or metastasis. Double cancers were detected by PET in 3 patients (1.9%): lung and esophageal cancer, gastric cancer, and ovarian cancer in one patient each. These 3 cases also were detected by PET for the first time and were free of clinical symptoms. Radical therapy was performed in 2 patients. The other patient had advanced disease and received only palliative therapy. Although PET could not detect most cancers or precancerous lesions in the upper gastrointestinal tract that could be detected by gastrointestinal endscopy, it was useful for detecting malignant lesions in sites other than the upper gastrointestinal tract. Our results suggest that preoperative gastrointestinal endscopy and PET examinations can detect double cancer in the early stage and contribute to better outcomes in patients with oral cancer.

    Full Text Available BACKGROUND : Incidence of rectal cancer has wide geographical variation. Disease pattern in developing countries is different from developed countries as majority of the patients present in advanced stage because of delayed referral and lack of uniform treatment practices. AIMS : Present study describes the patient profile and treatment results from a tertiary care cancer center in India. SETTING AND DESIGN : Tertiary care Regional cancer center. Retrospective analysis 89 patients with rectal adenocarcinoma treated between 1995 and 2002 were analyzed. METHODS: Patients with adenocarcinoma rectum were evaluated in a G.I. Oncology clinic and were treated using multimodality protocols involving surgery, radiotherapy and adjuvant chemotherapy. STATISTICAL ANALYSIS : A descriptive analysis of patient and disease profile,treatment patterns and out come was performed. Survival analysis was performed using Kaplan-Meier method. RESULTS : Mean age of the patients was 45.4 years and majority of them had tumor in lower third of rectum with evidence of extrarectal spread. Seventy five percent of the patients underwent curative resection with abdominoperineal resection being the commonest procedure. Forty seven percent of patients were given short course preoperative radiotherapy and the remaining received postoperative radiotherapy. Sixty four percent of patients could complete planned adjuvant chemotherapy. Operative mortality was 2% and 23% had morbidity. Local recurrence rate was 8.9%. 5-year disease free and overall survival was 54% and 58% respectively. CONCLUSION : Majority of rectal cancer patients present with locally advanced and low rectal growths leading to low sphincter salvage rates. Despite the advanced stage of presentation optimal oncologic results can be obtained by using a good surgical techniques in combination with adjuvant radiotherapy and chemotherapy. Short course preoperative radiotherapy seems to be more feasible in Indian context

    AIM: To assess H pylori seroprevalence in lung cancer and determine whether there is a potential association between lung cancer and H pylori infection.METHODS: The study was conducted on forty consecutive patients with lung cancer, confirmed by pathology (32 men, 8 women; mean age 55.50 ± 11.91 years,range 16-77 years).Forty healthy subjects (25 men,15 women;mean age 43.08 ± 12.60 years,range 20-79 years) from the patients' family members were matched to each case Subject on the basis of age and socioeconomic status.H pylori infection was detected with a commercially available immunoglobulin G (IgG) enzyme-linked immunosorbent assay (Trinity kit,Biotech co.,USA),previously validated in adults (86% sensitivity,96% specificity) against a gold standard of culture and histology.RESULTS: H pylori seropositivity was present in 52.5% of patients with lung cancer in comparison to 45.0% of healthy control subjects. Although H pylori seropositivity was more frequent in lung cancer patients than in controls, the difference did not reach statistical significance (OR = 1.35, 95% CI = 0.56-3.25; P = 0.65). In addition, there was no significant difference between cases and controls in terms of gastrointestinal symptoms.CONCLUSION: The earlier described association between H pylori infection and lung cancer was not supported in this study. Further studies with larger sample sizes should be undertaken to assess the frequency of H pylori infection in patients with lung cancer and their potential association.

    Full Text Available Background: The balance of the Th1 and Th2 immune response plays an important role inthe regulation of the immune system and in general health. Tumor bearinghosts are supposed to have a balance shifting to the Th2 pathway, while afavorable Th1 anti-tumor pathway is induced in tumor-resected hosts. Theclinical impacts of a tumor-related Th2 environment have not been clearlystudied. The present study was conducted to test the hypothesis that nonsmallcell lung cancer (NSCLC has an impact on control of asthma, a wellknownTh2-predominant inflammatory disease.Method: Thirty-eight patients with the diagnoses of both asthma and lung cancer wereretrospectively enrolled. Patients were divided into two groups according totheir response to lung cancer treatment, the responder group (completeregression, partial regression and stable disease and non-responder group(progression of disease. Asthma control test (ACT scores were analyzedone year before diagnosis, at the time of diagnosis of lung cancer, and at thetime of re-staging after cancer treatment.Results: All the asthmatics with lung cancer had worsening of their symptomsaccording to their ACT scores at the time of diagnosis of lung cancer comparedto scores in the preceding year (21.6

    Fatigue is a common complication in cancer patients, particularly in those receiving chemotherapy, with important negative effects on quality of life. It is not sufficiently studied, not completely understood and does not receive adequate consideration. The aim of this study is to improve knowledge on epidemiology, aetiology and treatment of fatigue in cancer patients in Italy. Answers to a questionnaire administered to 300 hematologists and a similar number of patients with hematological cancer have been evaluated. According to the opinion of hematologists and the experience of patients, fatigue is the most frequent and long-lasting symptom in patients with hematological cancer compromising their quality of life. The majority of the patients of the study group reports fatigue along the course of their disease, and this symptom is prominent in how it affects the different aspects of quality of life: their daily routine, working and social interaction according to clinicians; physical and emotional well-being according to patients. The results of the hematologist study group found anemia to be the leading cause of cancer-related fatigue. For the management of the symptom, the treatment of anemia is mainly done with transfusion and drugs, and it is advisable in the majority of the patients. There is still debate on the definition of anemia: hemoglobin (Hb) levels < 8 g/dl according to one third of the clinicians and greater values up to 10-11 g/dl for the others. According to the hematologists of the study group, a treatment for fatigue is generally recommended for the majority of the cancer patients, yet patients reported that, on the contrary, 50% of their hematologists did not suggest any specific treatment for this aim.

    Background. The diagnosis, treatment, and long-term management of cancer can present individuals with a multitude of stressors at various points in that trajectory. Psychosocial distress may appear early in the diagnostic process and have negative effects on compliance with treatment and subsequent quality of life. Purpose. The aim of the study was to determine early-phase predictors of distress before any medical treatment. Method. Consistent with the goals of the study, 123 newly diagnosed breast cancer patients (20 to 74 years old) completed multiple indicators of knowledge about breast cancer management and treatment, attitudes toward cancer, social support, coping efficacy, and distress. Results. SEM analysis confirmed the hypothesized model. Age was negatively associated with the patient's knowledge (β = - 0.22), which, in turn, was positively associated with both attitudes toward breast cancer (β = 0.39) and coping self-efficacy (β = 0.36). Self-efficacy was then directly related to psychological distress (β = - 0.68). Conclusions. These findings establish indicators of distress in patients early in the cancer trajectory. From a practical perspective, our results have implications for screening for distress and for the development of early interventions that may be followed by healthcare professionals to reduce psychological distress.

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

    International Nuclear Information System (INIS)

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

    Globally, there are approximately 7.4 million cancer deaths annually, approximately 13% of deaths from all causes. Cancer is a disease of older people and, as the population ages over the next 10-20 years, we can expect an increase in the cancer incidence. Encouragingly, cancer mortality has stabilized in many countries. Part of this success may be attributed to the development of new cancer agents, collectively called 'targeted therapies', that are more specific to key components of tumour growth. Worldwide, however, one of the main factors that limit patient access to these important new drugs is their cost, which is higher than traditional chemotherapy. In this review, the clinical and pharmacoeconomic data of selected targeted agents are discussed. In the second part of this article, the challenges faced by healthcare systems in making such drugs available to patients is reviewed. Current strategies used by many countries around the world to manage cancer drug budgets are presented, along with a proposed approach using pharmacoeconomic methodology that may increase patient access.

    There is a high prevalence of depression after cancer treatment. In the literature, several authors have raised questions about assessing somatic symptoms to explore depression after cancer treatment. These somatic sequelae are a consequence of cancer treatment and should cause higher depression rates in cancer patients. In this study, the Somatic domain on a depression questionnaire, the Center for Epidemiologic Studies-Depression scale (CES-D) was analyzed in different cancer patients after...

    Objective:To find an effective treatment for advanced cancer patients with esophageal fistula. Methods:From 1998 to 2006, we studied 42 patients with advanced esophageal cancer and 5 lung cancer patients with carcinomatous esophageal fistula(3 females,44 males,aged 29-92 years). Ten patients with both esophageal cancer stricture and fistula were first dilated under endoscope,then a memory stent with a membrane was placed in the esophageal lumen. Others were treated only with a memory stent with a membrane,three of them with a large fistula(diameter>1.5 cm)were treated with bio-protein glue after placement of an esophageal metal stent.Results:The fistulas were covered by a stent and the patients could eat and drink immediately.Their quality of life was improved and their survival was prolonged, 44 out of 47 patients survived for>3 mo. Conclusion:Placement of esophageal stent with membrane or in combination with bio-protein glue through endoscope is an effective method for treating the bronchoesophageal fistula.

    Full Text Available SUMMARY Objective: To describe the clinical and sociodemographic profile of cancer patients admitted to the Emergency Center for High Complexity Oncologic Assistance, observing the coverage of palliative and home care. Method: Cross sectional study including adult cancer patients admitted to the emergency service (September-December/2011 with a minimum length of hospital stay of two hours. Student’s t-test and Pearson chi-square test were used to compare the means. Results: 191 patients were enrolled, 47.6% elderly, 64.4% women, 75.4% from the city of Recife and greater area. The symptom prevalent at admission was pain (46.6%. 4.2% of patients were linked to palliative care and 2.1% to home care. The most prevalent cancers: cervix (18.3%, breast (13.6% and prostate (10.5%; 70.7% were in advanced stages (IV, 47.1%; 39.4% without any cancer therapy. Conclusion: Patients sought the emergency service on account of pain, probably due to the incipient coverage of palliative and home care. These actions should be included to oncologic therapy as soon as possible to minimize the suffering of the patient/family and integrate the skills of oncologists and emergency professionals.
