The breast cancer is one of the biggest health problems worldwide, is the most diagnosed cancer in women and prevention seems impossible since its cause is unknown, due to this; the early detection has a key role in the patient prognosis. In developing countries such as Mexico, where access to specialized health services is minimal, the regular clinical review is infrequent and there are not enough radiologists; the most common form of detection of breast cancer is through self-exploration, but this is only detected in later stages, when is already palpable. For these reasons, the objective of the present work is the creation of a system of computer assisted diagnosis (CAD x) using information analysis techniques such as data mining and advanced techniques of artificial intelligence, seeking to offer a previous medical diagnosis or a second opinion, as if it was a second radiologist in order to reduce the rate of mortality from breast cancer. In this paper, advances in the design of computational algorithms using computer vision techniques for the extraction of features derived from mammograms are presented. Using data mining techniques of data mining is possible to identify patients with a high risk of breast cancer. With the information obtained from the mammography analysis, the objective in the next stage will be to establish a methodology for the generation of imaging bio-markers to establish a breast cancer risk index for Mexican patients. In this first stage we present results of the classification of patients with high and low risk of suffering from breast cancer using neural networks. (Author)

Accurate prediction of the treatment outcome is important for cancer treatment planning. We present an approach to predict prostate cancer (PCa) recurrence after radical prostatectomy using tissue images. We used a cohort whose case vs. control (recurrent vs. non-recurrent) status had been determined using post-treatment follow up. Further, to aid the development of novel biomarkers of PCa recurrence, cases and controls were paired based on matching of other predictive clinical variables such as Gleason grade, stage, age, and race. For this cohort, tissue resection microarray with up to four cores per patient was available. The proposed approach is based on deep learning, and its novelty lies in the use of two separate convolutional neural networks (CNNs) - one to detect individual nuclei even in the crowded areas, and the other to classify them. To detect nuclear centers in an image, the first CNN predicts distance transform of the underlying (but unknown) multi-nuclear map from the input HE image. The second CNN classifies the patches centered at nuclear centers into those belonging to cases or controls. Voting across patches extracted from image(s) of a patient yields the probability of recurrence for the patient. The proposed approach gave 0.81 AUC for a sample of 30 recurrent cases and 30 non-recurrent controls, after being trained on an independent set of 80 case-controls pairs. If validated further, such an approach might help in choosing between a combination of treatment options such as active surveillance, radical prostatectomy, radiation, and hormone therapy. It can also generalize to the prediction of treatment outcomes in other cancers.

Full Text Available In India, the oral cancers are usually presented in advanced stage of malignancy. It is critical to ascertain the diagnosis in order to initiate most advantageous treatment of the suspicious lesions. The main hurdle in appropriate treatment and control of oral cancer is identification and risk assessment of early disease in the community in a cost-effective fashion. The objective of this research is to design a data mining model using probabilistic neural network and general regression neural network (PNN/GRNN for early detection and prevention of oral malignancy. The model is built using the oral cancer database which has 35 attributes and 1025 records. All the attributes pertaining to clinical symptoms and history are considered to classify malignant and non-malignant cases. Subsequently, the model attempts to predict particular type of cancer, its stage and extent with the help of attributes pertaining to symptoms, gross examination and investigations. Also, the model envisages anticipating the survivability of a patient on the basis of treatment and follow-up details. Finally, the performance of the PNN/GRNN model is compared with that of other classification models. The classification accuracy of PNN/GRNN model is 80% and hence is better for early detection and prevention of the oral cancer.

There are numerous unanswered questions in the application of artificial neural network models for analysis of survival data. In most studies, independent variables have been studied as qualitative dichotomous variables, and results of using discrete and continuous quantitative, ordinal, or multinomial categorical predictive variables in these models are not well understood in comparison to conventional models. This study was designed and conducted to examine the application of these models in order to determine the survival of gastric cancer patients, in comparison to the Cox proportional hazards model. We studied the postoperative survival of 330 gastric cancer patients who suffered surgery at a surgical unit of the Iran Cancer Institute over a five-year period. Covariates of age, gender, history of substance abuse, cancer site, type of pathology, presence of metastasis, stage, and number of complementary treatments were entered in the models, and survival probabilities were calculated at 6, 12, 18, 24, 36, 48, and 60 months using the Cox proportional hazards and neural network models. We estimated coefficients of the Cox model and the weights in the neural network (with 3, 5, and 7 nodes in the hidden layer) in the training group, and used them to derive predictions in the study group. Predictions with these two methods were compared with those of the Kaplan-Meier product limit estimator as the gold standard. Comparisons were performed with the Friedman and Kruskal-Wallis tests. Survival probabilities at different times were determined using the Cox proportional hazards and a neural network with three nodes in the hidden layer; the ratios of standard errors with these two methods to the Kaplan-Meier method were 1.1593 and 1.0071, respectively, revealed a significant difference between Cox and Kaplan-Meier (P neural network, and the neural network and the standard (Kaplan-Meier), as well as better accuracy for the neural network (with 3 nodes in the hidden layer

Approximately two thirds of cancer patients at advanced stages of the disease suffer from anorexia. Defined as the loss of the desire to eat, anorexia lower the energy intake which further exacerbates a progressive deterioration of the patient nutritional status. Malnutrition has a large impact on morbidity and mortality affecting the quality of life. Cancer anorexia etiology is multifactorial including complex interactions among the tumor, host metabolism and antineoplastic treatment. New related theories include peripheral and brain mechanisms affecting hypothalamic pathways; inducing behavioral and metabolic failure of responses to energy balance. The aim of this review is to describe actual concepts involved in the pathogenesis of cancer anorexia with special interest in brain mechanisms. Anorexia and reduced food intake are important issues in the management of cancer patients, more knowledge about pathogenic mechanism is needed to improve therapeutic options, prognosis and quality of life in cancer patients.

In cancer studies, the prediction of cancer outcome based on a set of prognostic variables has been a long-standing topic of interest. Current statistical methods for survival analysis offer the possibility of modelling cancer survivability but require unrealistic assumptions about the survival time distribution or proportionality of hazard. Therefore, attention must be paid in developing nonlinear models with less restrictive assumptions. Artificial neural network (ANN) models are primarily useful in prediction when nonlinear approaches are required to sift through the plethora of available information. The applications of ANN models for prognostic and diagnostic classification in medicine have attracted a lot of interest. The applications of ANN models in modelling the survival of patients with gastric cancer have been discussed in some studies without completely considering the censored data. This study proposes an ANN model for predicting gastric cancer survivability, considering the censored data. Five separate single time-point ANN models were developed to predict the outcome of patients after 1, 2, 3, 4, and 5 years. The performance of ANN model in predicting the probabilities of death is consistently high for all time points according to the accuracy and the area under the receiver operating characteristic curve.

2001-01-01

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

The incidence and mortality rate of the primary liver cancer are very high and its postoperative metastasis and recurrence have become important factors to the prognosis of patients. Circulating tumor cells (CTC), as a new tumor marker, play important roles in the early diagnosis and individualized treatment. This paper presents an effective method to distinguish liver cancer based on the cellular scattering spectrum, which is a non-fluorescence technique based on the fiber confocal microscopic spectrometer. Combining the principal component analysis (PCA) with back propagation (BP) neural network were utilized to establish an automatic recognition model for backscatter spectrum of the liver cancer cells from blood cell. PCA was applied to reduce the dimension of the scattering spectral data which obtained by the fiber confocal microscopic spectrometer. After dimensionality reduction by PCA, a neural network pattern recognition model with 2 input layer nodes, 11 hidden layer nodes, 3 output nodes was established. We trained the network with 66 samples and also tested it. Results showed that the recognition rate of the three types of cells is more than 90%, the relative standard deviation is only 2.36%. The experimental results showed that the fiber confocal microscopic spectrometer combining with the algorithm of PCA and BP neural network can automatically identify the liver cancer cell from the blood cells. This will provide a better tool for investigating the metastasis of liver cancers in vivo, the biology metabolic characteristics of liver cancers and drug transportation. Additionally, it is obviously referential in practical application.

Obesity is one of the most challenging problems in human health and is recognized as an important risk factor for many chronic diseases. It remains unclear how the neural systems (e.g., the mesolimbic "reward" and the prefrontal "control" neural systems) are correlated with patients' executive function (EF), conceptualized as the integration of "cool" EF and "hot" EF. "Cool" EF refers to relatively abstract, non-affective operations such as inhibitory control and mental flexibility. "Hot" EF refers to motivationally significant affective operations such as affective decision-making. We tried to find the correlation between structural and functional neuroimaging indices and EF in obese patients. The study population comprised seventeen patients with obesity (seven males and 10 females, BMI = 37.99 ± 5.40, age = 31.82 ± 8.75 year-old) preparing to undergo bariatric surgery. We used noninvasive diffusion tensor imaging, generalized q-sampling imaging, and resting-state functional magnetic resonance imaging to examine the neural correlations between structural and functional neuroimaging indices and EF performances in patients with obesity. We reported that many brain areas are correlated to the patients' EF performances. More interestingly, some correlations may implicate the possible associations of EF and the incentive motivational effects of food. The neural correlation between the left precuneus and middle occipital gyrus and inhibitory control may suggest that patients with a better ability to detect appetitive food may have worse inhibitory control. Also, the neural correlation between the superior frontal blade and affective decision-making may suggest that patients' affective decision-making may be associated with the incentive motivational effects of food. Our results provide evidence suggesting neural correlates of EF in patients with obesity.

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.

Taiwan is an area where chronic hepatitis is endemic. Liver cancer is so common that it has been ranked first among cancer mortality rates since the early 1980s in Taiwan. Besides, liver cirrhosis and chronic liver diseases are the sixth or seventh in the causes of death. Therefore, as shown by the active research on hepatitis, it is not only a health threat, but also a huge medical cost for the government. The estimated total number of hepatitis B carriers in the general population aged more than 20 years old is 3,067,307. Thus, a case record review was conducted from all patients with diagnosis of acute hepatitis admitted to the Emergency Department (ED) of a well-known teaching-oriented hospital in Taipei. The cost of medical resource utilization is defined as the total medical fee. In this study, a fuzzy neural network is employed to develop the cost forecasting model. A total of 110 patients met the inclusion criteria. The computational results indicate that the FNN model can provide more accurate forecasts than the support vector regression (SVR) or artificial neural network (ANN). In addition, unlike SVR and ANN, FNN can also provide fuzzy IF-THEN rules for interpretation. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The aim of this study was to develop an effective surgical site infection (SSI) prediction model in patients receiving free-flap reconstruction after surgery for head and neck cancer using artificial neural network (ANN), and to compare its predictive power with that of conventional logistic regression (LR). There were 1,836 patients with 1,854 free-flap reconstructions and 438 postoperative SSIs in the dataset for analysis. They were randomly assigned tin ratio of 7:3 into a training set and a test set. Based on comprehensive characteristics of patients and diseases in the absence or presence of operative data, prediction of SSI was performed at two time points (pre-operatively and post-operatively) with a feed-forward ANN and the LR models. In addition to the calculated accuracy, sensitivity, and specificity, the predictive performance of ANN and LR were assessed based on area under the curve (AUC) measures of receiver operator characteristic curves and Brier score. ANN had a significantly higher AUC (0.892) of post-operative prediction and AUC (0.808) of pre-operative prediction than LR (both P <0.0001). In addition, there was significant higher AUC of post-operative prediction than pre-operative prediction by ANN (p<0.0001). With the highest AUC and the lowest Brier score (0.090), the post-operative prediction by ANN had the highest overall predictive performance. The post-operative prediction by ANN had the highest overall performance in predicting SSI after free-flap reconstruction in patients receiving surgery for head and neck cancer.

The paper presents a deep learning approach for automatic classification of breast tumors based on fine needle cytology. The main aim of the system is to distinguish benign from malignant cases based on microscopic images. Experiment was carried out on cytological samples derived from 50 patients (25 benign cases + 25 malignant cases) diagnosed in Regional Hospital in Zielona Góra. To classify microscopic images, we used convolutional neural networks (CNN) of two types: GoogLeNet and AlexNet. Due to the very large size of images of cytological specimen (on average 200000 × 100000 pixels), they were divided into smaller patches of size 256 × 256 pixels. Breast cancer classification usually is based on morphometric features of nuclei. Therefore, training and validation patches were selected using Support Vector Machine (SVM) so that suitable amount of cell material was depicted. Neural classifiers were tuned using GPU accelerated implementation of gradient descent algorithm. Training error was defined as a cross-entropy classification loss. Classification accuracy was defined as the percentage ratio of successfully classified validation patches to the total number of validation patches. The best accuracy rate of 83% was obtained by GoogLeNet model. We observed that more misclassified patches belong to malignant cases.

Computational intelligence methods, including non-linear classification algorithms, can be used in medical research and practice as a decision making tool. This study aimed to evaluate the usefulness of artificial intelligence models for 5-year overall survival prediction in patients with cervical cancer treated by radical hysterectomy. The data set was collected from 102 patients with cervical cancer FIGO stage IA2-IIB, that underwent primary surgical treatment. Twenty-three demographic, tumor-related parameters and selected perioperative data of each patient were collected. The simulations involved six computational intelligence methods: the probabilistic neural network (PNN), multilayer perceptron network, gene expression programming classifier, support vector machines algorithm, radial basis function neural network and k-Means algorithm. The prediction ability of the models was determined based on the accuracy, sensitivity, specificity, as well as the area under the receiver operating characteristic curve. The results of the computational intelligence methods were compared with the results of linear regression analysis as a reference model. The best results were obtained by the PNN model. This neural network provided very high prediction ability with an accuracy of 0.892 and sensitivity of 0.975. The area under the receiver operating characteristics curve of PNN was also high, 0.818. The outcomes obtained by other classifiers were markedly worse. The PNN model is an effective tool for predicting 5-year overall survival in cervical cancer patients treated with radical hysterectomy.

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.

According to current concepts, major depressive disorder is strongly related to dysfunctional neural processing of motivational information, entailing impairments in reinforcement learning. While computational modelling can reveal the precise nature of neural learning signals, it has not been used to study learning-related neural dysfunctions in unmedicated patients with major depressive disorder so far. We thus aimed at comparing the neural coding of reward and punishment prediction errors, representing indicators of neural learning-related processes, between unmedicated patients with major depressive disorder and healthy participants. To this end, a group of unmedicated patients with major depressive disorder (n = 28) and a group of age- and sex-matched healthy control participants (n = 30) completed an instrumental learning task involving monetary gains and losses during functional magnetic resonance imaging. The two groups did not differ in their learning performance. Patients and control participants showed the same level of prediction error-related activity in the ventral striatum and the anterior insula. In contrast, neural coding of reward prediction errors in the medial orbitofrontal cortex was reduced in patients. Moreover, neural reward prediction error signals in the medial orbitofrontal cortex and ventral striatum showed negative correlations with anhedonia severity. Using a standard instrumental learning paradigm we found no evidence for an overall impairment of reinforcement learning in medication-free patients with major depressive disorder. Importantly, however, the attenuated neural coding of reward in the medial orbitofrontal cortex and the relation between anhedonia and reduced reward prediction error-signalling in the medial orbitofrontal cortex and ventral striatum likely reflect an impairment in experiencing pleasure from rewarding events as a key mechanism of anhedonia in major depressive disorder. © The Author (2017).

2013-01-01

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)

We investigated the clinical, electrophysiological and neural autoantibody characteristics in cramp-fasciculation syndrome (CFS) patients. We reviewed Mayo Clinic records from 2000 to 2011 to identify clinically defined CFS patients who underwent neural autoantibody testing. Stored sera of patients who tested positive for antibodies to voltage-gated potassium channel complex (VGKC complex) were analyzed further for leucine-rich glioma-inactivated 1 (LGI1) or contactin-associated protein-2 immunoglobulin G (CASPR2-IgG) antibodies. Thirty-seven patients were identified. Twelve were seropositive for neural autoantibodies. Clinical manifestations were similar in seropositive and seronegative patients, although central and autonomic neuronal hyperexcitability symptoms were more common in seropositive cases. No patients had a malignancy. Repetitive tibial nerve stimulation at 10 Hz revealed longer afterdischarges in seropositive patients. Two of 7 patients with VGKC-complex autoimmunity demonstrated LGI1 or CASPR2-IgG antibodies. Only 2 of 12 seropositive patients required immunotherapy. VGKC-complex autoimmunity occurs in a minority of CFS patients. Antibody positivity was associated with extramuscular manifestations, typically without malignancy. Target antigens within the VGKC complex remain unknown in most patients. Published 2013 by Wiley Periodicals, Inc.

Artificial neural networks (ANNs) are computer programs used to identify complex relations within data. Routine predictions of presence of colorectal pathology based on population statistics have little meaning for individual patient. This results in large number of unnecessary lower gastrointestinal endoscopies (LGEs - colonoscopies and flexible sigmoidoscopies). We aimed to develop a neural network algorithm that can accurately predict presence of significant pathology in patients attending routine outpatient clinics for gastrointestinal symptoms. Ethics approval was obtained and the study was monitored according to International Committee on Harmonisation - Good Clinical Practice (ICH-GCP) standards. Three-hundred patients undergoing LGE prospectively completed a specifically developed questionnaire, which included 40 variables based on clinical symptoms, signs, past- and family history. Complete data sets of 100 patients were used to train the ANN; the remaining data was used for internal validation. The primary output used was positive finding on LGE, including polyps, cancer, diverticular disease or colitis. For external validation, the ANN was applied to data from 50 patients in primary care and also compared with the predictions of four clinicians. Clear correlation between actual data value and ANN predictions were found (r = 0.931; P = 0.0001). The predictive accuracy of ANN was 95% in training group and 90% (95% CI 84-96) in the internal validation set and this was significantly higher than the clinical accuracy (75%). ANN also showed high accuracy in the external validation group (89%). Artificial neural networks offer the possibility of personal prediction of outcome for individual patients presenting in clinics with colorectal symptoms, making it possible to make more appropriate requests for lower gastrointestinal endoscopy. © 2010 The Authors.

Image recognition using artificial intelligence with deep learning through convolutional neural networks (CNNs) has dramatically improved and been increasingly applied to medical fields for diagnostic imaging. We developed a CNN that can automatically detect gastric cancer in endoscopic images. A CNN-based diagnostic system was constructed based on Single Shot MultiBox Detector architecture and trained using 13,584 endoscopic images of gastric cancer. To evaluate the diagnostic accuracy, an independent test set of 2296 stomach images collected from 69 consecutive patients with 77 gastric cancer lesions was applied to the constructed CNN. The CNN required 47 s to analyze 2296 test images. The CNN correctly diagnosed 71 of 77 gastric cancer lesions with an overall sensitivity of 92.2%, and 161 non-cancerous lesions were detected as gastric cancer, resulting in a positive predictive value of 30.6%. Seventy of the 71 lesions (98.6%) with a diameter of 6 mm or more as well as all invasive cancers were correctly detected. All missed lesions were superficially depressed and differentiated-type intramucosal cancers that were difficult to distinguish from gastritis even for experienced endoscopists. Nearly half of the false-positive lesions were gastritis with changes in color tone or an irregular mucosal surface. The constructed CNN system for detecting gastric cancer could process numerous stored endoscopic images in a very short time with a clinically relevant diagnostic ability. It may be well applicable to daily clinical practice to reduce the burden of endoscopists.

Full Text Available Skeletal muscles in patients with cancer undergo many changes due to immuno-inflammatory factors of tumor origin, or to chemotherapy and irradiation. 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

When given in single doses to healthy volunteers, opioid analgesics impair reaction time, muscle coordination, attention, and short-term memory sufficiently to affect driving and other skilled activities. Despite the increasing use of oral morphine daily, little is known about the effect of long-term opioid therapy on psychomotor performance. To examine the effects of continuous morphine medication, psychological and neurological tests originally designed for professional motor vehicle drivers were conducted in two groups of cancer patients who were similar apart from experience of pain. 24 were on continuous morphine (mean 209 mg oral morphine daily) for cancer pain; and 25 were pain-free without regular analgesics. Though the results were a little worse in the patients taking morphine, there were no significant differences between the groups in intelligence, vigilance, concentration, fluency of motor reactions, or division of attention. Of the neural function tests, reaction times (auditory, visual, associative), thermal discrimination, and body sway with eyes open were similar in the two groups; only balancing ability with closed eyes was worse in the morphine group. These results indicate that, in cancer patients receiving long-term morphine treatment with stable doses, morphine has only a slight and selective effect on functions related to driving.

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.

Full Text Available It is not enough to consider treatment and care depression in the oncology that is the most common psychiatric illness in cancer patient affects of cancer treatment and the patient`s quality of life negatively, which is determined through researches in the field. 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.

Successful outcomes of surgical cancer resection necessitate negative, cancer-free surgical margins. Currently, tissue samples are sent to pathology for diagnostic confirmation. Hyperspectral imaging (HSI) is an emerging, non-contact optical imaging technique. A reliable optical method could serve to diagnose and biopsy specimens in real-time. Using convolutional neural networks (CNNs) as a tissue classifier, we developed a method to use HSI to perform an optical biopsy of ex-vivo surgical specimens, collected from 21 patients undergoing surgical cancer resection. Training and testing on samples from different patients, the CNN can distinguish squamous cell carcinoma (SCCa) from normal aerodigestive tract tissues with an area under the curve (AUC) of 0.82, 81% accuracy, 81% sensitivity, and 80% specificity. Additionally, normal oral tissues can be sub-classified into epithelium, muscle, and glandular mucosa using a decision tree method, with an average AUC of 0.94, 90% accuracy, 93% sensitivity, and 89% specificity. After separately training on thyroid tissue, the CNN differentiates between thyroid carcinoma and normal thyroid with an AUC of 0.95, 92% accuracy, 92% sensitivity, and 92% specificity. Moreover, the CNN can discriminate medullary thyroid carcinoma from benign multi-nodular goiter (MNG) with an AUC of 0.93, 87% accuracy, 88% sensitivity, and 85% specificity. Classical-type papillary thyroid carcinoma is differentiated from benign MNG with an AUC of 0.91, 86% accuracy, 86% sensitivity, and 86% specificity. Our preliminary results demonstrate that an HSI-based optical biopsy method using CNNs can provide multi-category diagnostic information for normal head-and-neck tissue, SCCa, and thyroid carcinomas. More patient data are needed in order to fully investigate the proposed technique to establish reliability and generalizability of the work.

There is evidence that women with breast cancer show a cognitive impairment after having undergone chemotherapy treatment; this cognitive impairment may result in behavioral deficits. However, the neural mechanism of this cognitive impairment remains unclear. The present study investigated the neural basis of the cognitive impairment caused by chemotherapy treatment by exploring the decision-making function of the executive subcomponents under ambiguity and risk in breast cancer survivors. Participants included breast cancer patients who had undergone chemotherapy (CT, N=63) or patients who did not undergo chemotherapy (non-CT, N=62), as well as matched healthy controls (HC, N=61). All participants were examined using the Iowa Gambling Task (IGT) to assess their decision-making under ambiguity, the Game of Dice Task (GDT) to assess their decision-making under risk and neuropsychological background tests. Our results indicated that during the IGT test, the chemotherapy-treated breast cancer patients selected from the disadvantageous decks with a higher frequency than the non-treated breast cancer patients or healthy controls, whereas all three groups performed at the same level when performing the GDT. The CT group demonstrated significantly lower scores in several cognitive tasks, including attention, memory, executive functions and cognitive processing, when compared with the other two groups. In addition, within the CT group, significant correlations were found between the IGT performance and information processing, as well as with working memory. This study demonstrated that breast cancer survivors treated with chemotherapy may have selective reductions in IGT performance but unimpaired GDT performance and that these deficits may result from dysfunctions in the limbic loop rather than in the dorsolateral prefrontal loop. © 2013 Elsevier B.V.

Better understanding of the dose-toxicity relationship is critical for safe dose escalation to improve local control in late-stage cervical cancer radiotherapy. In this study, we introduced a convolutional neural network (CNN) model to analyze rectum dose distribution and predict rectum toxicity. Forty-two cervical cancer patients treated with combined external beam radiotherapy (EBRT) and brachytherapy (BT) were retrospectively collected, including twelve toxicity patients and thirty non-toxicity patients. We adopted a transfer learning strategy to overcome the limited patient data issue. A 16-layers CNN developed by the visual geometry group (VGG-16) of the University of Oxford was pre-trained on a large-scale natural image database, ImageNet, and fine-tuned with patient rectum surface dose maps (RSDMs), which were accumulated EBRT  +  BT doses on the unfolded rectum surface. We used the adaptive synthetic sampling approach and the data augmentation method to address the two challenges, data imbalance and data scarcity. The gradient-weighted class activation maps (Grad-CAM) were also generated to highlight the discriminative regions on the RSDM along with the prediction model. We compare different CNN coefficients fine-tuning strategies, and compare the predictive performance using the traditional dose volume parameters, e.g. D 0.1/1/2cc, and the texture features extracted from the RSDM. Satisfactory prediction performance was achieved with the proposed scheme, and we found that the mean Grad-CAM over the toxicity patient group has geometric consistence of distribution with the statistical analysis result, which indicates possible rectum toxicity location. The evaluation results have demonstrated the feasibility of building a CNN-based rectum dose-toxicity prediction model with transfer learning for cervical cancer radiotherapy.

Breast Cancer is a serious threat and one of the largest causes of death of women throughout the world. The identification of cancer largely depends on digital biomedical photography analysis such as histopathological images by doctors and physicians. Analyzing histopathological images is a nontrivial task, and decisions from investigation of these kinds of images always require specialised knowledge. However, Computer Aided Diagnosis (CAD) techniques can help the doctor make more reliable decisions. The state-of-the-art Deep Neural Network (DNN) has been recently introduced for biomedical image analysis. Normally each image contains structural and statistical information. This paper classifies a set of biomedical breast cancer images (BreakHis dataset) using novel DNN techniques guided by structural and statistical information derived from the images. Specifically a Convolutional Neural Network (CNN), a Long-Short-Term-Memory (LSTM), and a combination of CNN and LSTM are proposed for breast cancer image classification. Softmax and Support Vector Machine (SVM) layers have been used for the decision-making stage after extracting features utilising the proposed novel DNN models. In this experiment the best Accuracy value of 91.00% is achieved on the 200x dataset, the best Precision value 96.00% is achieved on the 40x dataset, and the best F -Measure value is achieved on both the 40x and 100x datasets.

Full Text Available Background: One of the major consequences of breast cancer is the recurrence of the disease. The objective of present study was to estimate the 7-year survival without recurrence as well as the effective prognostic factors in recurrence. Materials and Methods: This historical cohort survival analysis was conducted on 1329 patients diagnosed with breast cancer in Motahari Breast Clinic, Shiraz, Iran between 2004 and 2011. We estimated the rate of survival without recurrence through the Kaplan–Meier method and the difference between the survival curves was investigated using the log-rank test. Furthermore, Cox regression model was used to model the effective factors in local recurrence as well as metastasis. Results: The mean age of the patients was 54.8 ± 11.4 years. Estrogen receptor positive, progesterone receptor positive, and human epidermal growth factor receptor-2 positive were observed in 70.6%, 66.6%, and 34.4% of the cases, respectively. The mean of the follow-up period was 3.7 ± 1.8 years in all patients. The results of the Kaplan–Meier method revealed 1-, 3-, 5-, and 7-year rate of survival without recurrence as 96.4%, 78.4%, 66.3%, and 54.8%, respectively. There was a significant relationship between survival without recurrence and histology grade (hazard ratio [HR] = 1.66, P = 0.009, neural invasion (HR = 1.74, P = 0.006, and progesterone receptors (HR = 0.69, P = 0.031. Conclusion: In this study, the rate of survival without recurrence in breast cancer was 54.8%. Among factors, histology grade and neural involvement at the time of diagnosis increased the chance of recurrence and progesterone receptors caused a longer interval between diagnosis and recurrence.

INTRODUCTION: Lung cancer remains a leading cause of cancer-related death. The incidence increases with age and the occurrence in young patients is relatively low. The clinicopathological features of lung cancer in younger patients have not been fully explored previously. METHODS: To assess the age...... differences in the clinical characteristics of lung cancer, we conducted a retrospective analysis comparing young patients ≤ 65 years of age with an elderly group > 65 years of age. Among 1,232 patients evaluated due to suspicion of lung cancer in our fast-track setting from January-December 2013, 312 newly...... diagnosed lung cancer patients were included. RESULTS: Patients ≤ 65 years had a significantly higher representation of females (p = 0.0021), more frequent familial cancer aggregation (p = 0.028) and a lower incidence of squamous cell carcinoma (p = 0.0133). When excluding pure carcinoid tumours...

Abstract Background: Tamoxifen is the most widely used drug for treating patients with estrogen receptor-sensitive breast cancer. There is evidence that breast cancer patients treated with tamoxifen exhibit cognitive dysfunction. However, the underlying neural mechanism remains unclear. The present study aimed to investigate the neural mechanisms underlying working memory deficits in combination with functional connectivity changes in premenopausal women with breast cancer who received long-term tamoxifen treatment. Methods: A total of 31 premenopausal women with breast cancer who received tamoxifen and 32 matched healthy control participants were included. The participants completed n-back tasks and underwent resting-state functional magnetic resonance imaging, which measure working memory performance and brain functional connectivity, respectively. A seed-based functional connectivity analysis within the whole brain was conducted, for which the dorsolateral prefrontal cortex was chosen as the seed region. Results: Our results indicated that the tamoxifen group had significant deficits in working memory and general executive function performance and significantly lower functional connectivity of the right dorsolateral prefrontal cortex with the right hippocampus compared with the healthy controls. There were no significant changes in functional connectivity in the left dorsolateral prefrontal cortex within the whole brain between the tamoxifen group and healthy controls. Moreover, significant correlations were found in the tamoxifen group between the functional connectivity strength of the dorsolateral prefrontal cortex with the right hippocampus and decreased working memory performance. Conclusion: This study demonstrates that the prefrontal cortex and hippocampus may be affected by tamoxifen treatment, supporting an antagonistic role of tamoxifen in the long-term treatment of breast cancer patients.

To evaluate deep learning in the assessment of breast cancer risk in which convolutional neural networks (CNNs) with transfer learning are used to extract parenchymal characteristics directly from full-field digital mammographic (FFDM) images instead of using computerized radiographic texture analysis (RTA), 456 clinical FFDM cases were included: a "high-risk" BRCA1/2 gene-mutation carriers dataset (53 cases), a "high-risk" unilateral cancer patients dataset (75 cases), and a "low-risk dataset" (328 cases). Deep learning was compared to the use of features from RTA, as well as to a combination of both in the task of distinguishing between high- and low-risk subjects. Similar classification performances were obtained using CNN [area under the curve [Formula: see text]; standard error [Formula: see text

Ultraviolet radiation (UVR) exposure and family history are major associated risk factors for the development of non-melanoma skin cancer (NMSC). The objective of this study was to develop and validate a multi-parameterized artificial neural network based on available personal health information for early detection of NMSC with high sensitivity and specificity, even in the absence of known UVR exposure and family history. The 1997-2015 NHIS adult survey data used to train and validate our neural network (NN) comprised of 2,056 NMSC and 460,574 non-cancer cases. We extracted 13 parameters for our NN: gender, age, BMI, diabetic status, smoking status, emphysema, asthma, race, Hispanic ethnicity, hypertension, heart diseases, vigorous exercise habits, and history of stroke. This study yielded an area under the ROC curve of 0.81 and 0.81 for training and validation, respectively. Our results (training sensitivity 88.5% and specificity 62.2%, validation sensitivity 86.2% and specificity 62.7%) were comparable to a previous study of basal and squamous cell carcinoma prediction that also included UVR exposure and family history information. These results indicate that our NN is robust enough to make predictions, suggesting that we have identified novel associations and potential predictive parameters of NMSC.

Patient experience is a critical dimension of cancer care quality. Understanding variation in experience among patients with different cancers and characteristics is an important first step for designing targeted improvement interventions. We analysed data from the 2011/2012 English Cancer Patient Experience Survey (n = 69,086) using logistic regression to explore inequalities in care experience across 64 survey questions. We additionally calculated a summary measure of variation in patient experience by cancer, and explored inequalities between patients with cancers treated by the same specialist teams. We found that younger and very old, ethnic minority patients and women consistently reported worse experiences across questions. Patients with small intestine/rarer lower gastrointestinal, multiple myeloma and hepatobiliary cancers were most likely to report negative experiences whereas patients with breast, melanoma and testicular cancer were least likely (top-to-bottom odds ratio = 1.91, P patients with cancers treated by the same specialty for five of nine services (P patients with ovarian, multiple myeloma, anal, hepatobiliary and renal cancer reported notably worse experiences than patients with other gynaecological, haematological, gastrointestinal and urological malignancies respectively. Initiatives to improve cancer patient experience across oncology services may be suitably targeted on patients at higher risk of poorer experience. © 2014 The Authors.

Prediction of Pathological Stage in Patients with Prostate Cancer: A Neuro-Fuzzy Model.

Directory of Open Access Journals (Sweden)

Georgina Cosma

Full Text Available 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

Previous research indicates abnormal comprehension of verbal information in patients with schizophrenia. Yet the neural mechanism underlying the breakdown of verbal information processing in schizophrenia is poorly understood. Imaging studies in healthy populations have shown a network of brain areas involved in hierarchical processing of verbal information over time. Here, we identified critical aspects of this hierarchy, examining patients with schizophrenia. Using functional magnetic resonance imaging, we examined various levels of information comprehension elicited by naturally presented verbal stimuli; from a set of randomly shuffled words to an intact story. Specifically, patients with first episode schizophrenia ( N  = 15), their non-manifesting siblings ( N  = 14) and healthy controls ( N  = 15) listened to a narrated story and randomly scrambled versions of it. To quantify the degree of dissimilarity between the groups, we adopted an inter-subject correlation (inter-SC) approach, which estimates differences in synchronization of neural responses within and between groups. The temporal topography found in healthy and siblings groups were consistent with our previous findings - high synchronization in responses from early sensory toward high order perceptual and cognitive areas. In patients with schizophrenia, stimuli with short and intermediate temporal scales evoked a typical pattern of reliable responses, whereas story condition (long temporal scale) revealed robust and widespread disruption of the inter-SCs. In addition, the more similar the neural activity of patients with schizophrenia was to the average response in the healthy group, the less severe the positive symptoms of the patients. Our findings suggest that system-level neural indication of abnormal verbal information processing in schizophrenia reflects disease manifestations.

Our findings suggest that system-level neural indication of abnormal verbal information processing in schizophrenia reflects disease manifestations.

Full Text Available Objectives. The incidence of cancer among the indigenous Sami people of Northern Finland is lower than among the Finnish general population. The survival of Sami cancer patients is not known, and therefore it is the object of this study. Study design. The cohort consisted of 2,091 Sami and 4,161 non-Sami who lived on 31 December 1978 in the two Sami municipalities of Inari and Utsjoki, which are located in Northern Finland and are 300–500 km away from the nearest central hospital. The survival experience of Sami and non-Sami cancer patients diagnosed in this cohort during 1979–2009 was compared with that of the Finnish patients outside the cohort. Methods. The Sami and non-Sami cancer patients were matched to other Finnish cancer patients for gender, age and year of diagnosis and for the site of cancer. An additional matching was done for the stage at diagnosis. Cancer-specific survival analyses were made using the Kaplan–Meier method and Cox regression modelling. Results. There were 204 Sami and 391 non-Sami cancer cases in the cohort, 20,181 matched controls without matching with stage, and 7,874 stage-matched controls. In the cancer-specific analysis without stage variable, the hazard ratio for Sami was 1.05 (95% confidence interval 0.85–1.30 and for non-Sami 1.02 (0.86–1.20, indicating no difference between the survival of those groups and other patients in Finland. Likewise, when the same was done by also matching the stage, there was no difference in cancer survival. Conclusion. Long distances to medical care or Sami ethnicity have no influence on the cancer patient survival in Northern Finland.

Sexuality is a basic need for every human being as long as he or she is alive, irrespective of age or health status. Approximately 23,500 individuals are diagnosed with cancer each year in Israel and join the 120,000 cancer patients currently living in Israel. The results of cancer treatments are traditionally assessed and based on the outcome regarding mortality versus survival. An equally important aspect to be addressed in this assessment must relate to quality of life. One of the more painful insults to the quality of life of cancer patients relates to the deleterious effects on sexuality. This article aims to present physicians with the spectrum of sexuality-related issues which are encountered by cancer patients and their partners, starting from the moment of diagnosis, throughout the various stages of treatment and to provide basic knowledge. Many individuals contracting cancer have difficulty dealing with the issue of sexuality. They are typically embarrassed and feel uneasy when asking health care providers about such a non-life threatening issue. Partners similarly feel both shame and guilt. In many cases sexuality, intimacy and emotional attachment are important aspects and may be essential for survival. Addressing these issues during treatment can provide patients with a sense of security, avoiding embarrassment and further exacerbation of such problems. Unfortunately, little has been done to develop an optimal interventional program, although standard sexual treatments have often been applied. Prospective clinical research and outcomes are missing. The physician can use the well-known PLISSIT model (1978): to provide sexuality involvement on different levels. The very new BETTER model (2004) can help emphasize that cancer treatment and the disease have an influence on intimacy and sexuality.

Full Text Available Cancer, which is one of the major health problems leading to despair, uncertainty, pain and suffering, is perceived as a serious and chronic disease. Cancer negatively affects individuals' quality of life due to the physical, psychological, and socio-economic problems. Today, despite inspiring advances in diagnosis and treatment of cancer and increase in survival rates of patients, appearance of physical and psycho-social disorders during cancer course disrupts the adaptation mechanisms of patients and undermines expectations for the future. Most of the time in clinical practice, clinicians focus on physical assessments and treatment planning of cancer patients primarily, ignoring social, psychological, economic and cultural factors related with the disease. This approach definitely influences patients' hope levels and their effective dealing with the disease. The aim of this article is to guide medical staff and increase awareness about the concept of hope in patients with cancer.

Breast cancer is the most common invasive cancer among women and its incidence is increasing. Risk assessment is valuable and recent methods are incorporating novel biomarkers such as mammographic density. Artificial neural networks (ANN) are adaptive algorithms capable of performing pattern-to-pattern learning and are well suited for medical applications. They are potentially useful for calibrating full-field digital mammography (FFDM) for quantitative analysis. This study uses ANN modeling to estimate volumetric breast density (VBD) from FFDM on Japanese women with and without breast cancer. ANN calibration of VBD was performed using phantom data for one FFDM system. Mammograms of 46 Japanese women diagnosed with invasive carcinoma and 53 with negative findings were analyzed using ANN models learned. ANN-estimated VBD was validated against phantom data, compared intra-patient, with qualitative composition scoring, with MRI VBD, and inter-patient with classical risk factors of breast cancer as well as cancer status. Phantom validations reached an R 2 of 0.993. Intra-patient validations ranged from R 2 of 0.789 with VBD to 0.908 with breast volume. ANN VBD agreed well with BI-RADS scoring and MRI VBD with R 2 ranging from 0.665 with VBD to 0.852 with breast volume. VBD was significantly higher in women with cancer. Associations with age, BMI, menopause, and cancer status previously reported were also confirmed. ANN modeling appears to produce reasonable measures of mammographic density validated with phantoms, with existing measures of breast density, and with classical biomarkers of breast cancer. FFDM VBD is significantly higher in Japanese women with cancer.

Cancer cachexia is a debilitating condition and results in poor prognosis. The purpose of this study was to assess hospitalization incidence, patient characteristics, and medical cost and burden of cancer cachexia in the US. This study used a cross-sectional analysis of the Nationwide Inpatient Sample (NIS) for 2009. Five cancers reported to have the highest cachexia incidence were assessed. The hospitalization incidence related to cachexia was estimated by cancer type, cost and length of stay were compared, and descriptive statistics were reported for each cancer type, as well as differences being compared between patients with and without cachexia. Risk of inpatient death was higher for patients with cachexia in lung cancer (OR = 1.32; CI = 1.20-1.46) and in all cancers combined (OR = 1.76; CI = 1.67-1.85). The presence of cachexia increased length of stay in lung (IRR = 1.05; CI = 1.03-1.08), Kaposi's sarcoma (IRR = 1.47; CI = 1.14-1.89) and all cancers combined (IRR = 1.09; CI = 1.08-1.10). Additionally, cachectic patients in the composite category had a longer hospitalization stay compared to non-cachectic patients (3-9 days for those with cachexia and 2-7 days for those without cachexia). The cost of inpatient stay was significantly higher in cachexic than non-cachexic lung cancer patients ($13,560 vs $13 190; p Cachexia increases hospitalization costs and length of stay in several cancer types. Identifying the medical burden associated with cancer cachexia will assist in developing an international consensus for recognition and coding by the medical community and ultimately an effective treatment plans for cancer cachexia.

We evaluated the potential of deep learning in the assessment of breast cancer risk using convolutional neural networks (CNNs) fine-tuned on full-field digital mammographic (FFDM) images. This study included 456 clinical FFDM cases from two high-risk datasets: BRCA1/2 gene-mutation carriers (53 cases) and unilateral cancer patients (75 cases), and a low-risk dataset as the control group (328 cases). All FFDM images (12-bit quantization and 100 micron pixel) were acquired with a GE Senographe 2000D system and were retrospectively collected under an IRB-approved, HIPAA-compliant protocol. Regions of interest of 256x256 pixels were selected from the central breast region behind the nipple in the craniocaudal projection. VGG19 pre-trained on the ImageNet dataset was used to classify the images either as high-risk or as low-risk subjects. The last fully-connected layer of pre-trained VGG19 was fine-tuned on FFDM images for breast cancer risk assessment. Performance was evaluated using the area under the receiver operating characteristic (ROC) curve (AUC) in the task of distinguishing between high-risk and low-risk subjects. AUC values of 0.84 (SE=0.05) and 0.72 (SE=0.06) were obtained in the task of distinguishing between the BRCA1/2 gene-mutation carriers and low-risk women and between unilateral cancer patients and low-risk women, respectively. Deep learning with CNNs appears to be able to extract parenchymal characteristics directly from FFDMs which are relevant to the task of distinguishing between cancer risk populations, and therefore has potential to aid clinicians in assessing mammographic parenchymal patterns for cancer risk assessment.

Full Text Available ABSTRACTBACKGROUNDNowadays cancer patients tend to be more involved in the medical decision process. Active participation improves health outcomes and patient satisfaction. To participate effectively patients require a huge amount of information, but time limits make it impossible to satisfy all information needs at clinics. We tried to find out which kind of media cancer patients use when searching for information and how often. Lastly, we try to find out how popular the Internet is in this regard.METODSIn this research we invited cancer patients, who had regular clinic examinations at the Oncology Institute between 21st and 25th May in 2012. We carried out a prospective research by anonymous questionnaires. We were investigating which media were used and how often. We analysed results with descriptive statistics, ANOVA, the χ²-Test and the t-test.RESULTS478 of 919 questionnaires distributed among cancer patients were returned. Mean age was 59.9 years. 61 % of responders were female, and the most common level of education was high school (33 %. Most common cancer type was breast cancer (33 %, followed by gastrointestinal and lung cancer. Patients search for information most often on television (81.4% responders, followed by specialized brochures (78%, internet (70.8% and newspapers (67.6%. Patients who do not use media for information searching are older than average (62.5 years vs. 59.9 years; p<0,000.CONCLUSIONSAccording to our results patients search for information most often on television, followed by brochures, internet and newspapers. Older patients less often search for information. This data might help doctors in everyday clinical practice.

Pain is a frequent but still neglected nonmotor symptom of Parkinson disease (PD). However, neural mechanisms underlying pain in PD are poorly understood. Here, we explored whether the high prevalence of pain in PD might be related to dysfunctional descending pain control. Using functional magnetic resonance imaging we explored neural responses during the anticipation and processing of heat pain in 21 PD patients (Hoehn and Yahr I-III) and 23 healthy controls (HC). Parkinson disease patients were naive to dopaminergic medication to avoid confounding drug effects. Fifteen heat pain stimuli were applied to the participants' forearm. Intensity and unpleasantness ratings were provided for each stimulus. Subjective pain perception was comparable for PD patients and HC. Neural processing, however, differed between groups: PD patients showed lower activity in several descending pain modulation regions (dorsal anterior cingulate cortex [dACC], subgenual anterior cingulate cortex, and dorsolateral prefrontal cortex [DLPFC]) and lower functional connectivity between dACC and DLPFC during pain anticipation. Parkinson disease symptom severity was negatively correlated with dACC-DLPFC connectivity indicating impaired functional coupling of pain modulatory regions with disease progression. During pain perception PD patients showed higher midcingulate cortex activity compared with HC, which also scaled with PD severity. Interestingly, dACC-DLPFC connectivity during pain anticipation was negatively associated with midcingulate cortex activity during the receipt of pain in PD patients. This study indicates altered neural processing during the anticipation and receipt of experimental pain in drug-naive PD patients. It provides first evidence for a progressive decline in descending pain modulation in PD, which might be related to the high prevalence of pain in later stages of PD.

Breast cancer is the second leading cause of cancer deaths in women today. Sometimes, breast cancer can return after primary treatment. A medical diagnosis of recurrent cancer is often a more challenging task than the initial one. In this paper, we investigate the potential contribution of neural networks (NNs) to support health professionals in diagnosing such events. The NN algorithms are tested and applied to two different datasets. An extensive statistical analysis has been performed to verify our experiments. The results show that a simple network structure for both the multi-layer perceptron and radial basis function can produce equally good results, not all attributes are needed to train these algorithms and, finally, the classification performances of all algorithms are statistically robust. Moreover, we have shown that the best performing algorithm will strongly depend on the features of the datasets, and hence, there is not necessarily a single best classifier.

Primary Patient-Derived Cancer Cells and Their Potential for Personalized Cancer Patient Care

Full Text Available Personalized cancer therapy is based on a patient’s tumor lineage, histopathology, expression analyses, and/or tumor DNA or RNA analysis. Here, we aim to develop an in vitro functional assay of a patient’s living cancer cells that could complement these approaches. We present methods for developing cell cultures from tumor biopsies and identify the types of samples and culture conditions associated with higher efficiency of model establishment. Toward the application of patient-derived cell cultures for personalized care, we established an immunofluorescence-based functional assay that quantifies cancer cell responses to targeted therapy in mixed cell cultures. Assaying patient-derived lung cancer cultures with this method showed promise in modeling patient response for diagnostic use. This platform should allow for the development of co-clinical trial studies to prospectively test the value of drug profiling on tumor-biopsy-derived cultures to direct patient care.

To assess the needs of cancer patients for information about their condition and to understand the psychological impact of their illness. The discussion of prognosis and treatment options in the palliative setting is an important and difficult part of oncology practice. To evaluate this, we examined the experiences of cancer patients of the physical and psychological impact of their disease on their life, and their opinions on the communication of end-of-life decisions and treatment options. A patient questionnaire was designed that encompassed communication regarding treatment and prognosis, quality-of-life attitudes subsequent to cancer diagnosis, end-of-life care and cancer drug funding. One hundred and twenty-five patients with a diagnosis of cancer were asked to participate and 96 questionnaires were completed and available for analysis. The questionnaire consisted of 63 questions and was completed in both an inpatient and outpatient setting. This survey brought to light a number of controversial issues in cancer service provision, highlighting the emotional and psychological changes brought about by a cancer diagnosis. Major concerns of our patients include fear of death and pain, changes in interpersonal relationships and financial constraints. Only 66% of the patients wanted to be given a prognosis by their clinicians and just 70% of the patients recalled being given a detailed prognosis. 11% of the patients were not prepared to undergo palliative treatment. In all, 7% were not prepared to accept treatment for 1 year and 2% for 5 years of life in exchange for the potential side effects of cytotoxic chemotherapy. 12% of the patients would not want to be in possession of the information that they were in the terminal phase of the illness with a short time to live and 16% would not want this discussed with their next of kin. This study informs medical professionals about the importance of tailoring information to the needs of the individual patient, and we

To compare the outcomes of patients having thyroid cancer among Filipinos vs non-Filipinos. Retrospective medical record review. High-volume tertiary referral center in Toronto, Ontario, Canada. A total of 499 patients with thyroid cancer (36 Filipino and 463 non-Filipino) treated at Mount Sinai Hospital from January 1, 1984, to August 31, 2003, with a minimum 5-year follow-up period and a minimum 1.0-cm tumor size. Patients were identified from a thyroid cancer database. Data on patient, tumor, and treatment factors were collected along with outcomes. The presence of thyroid cancer recurrence, the rate of death from disease, and the time to recurrence. The 2 groups were similar for sex, age, history of head and neck radiation exposure, family history of thyroid cancer, follow-up time, tumor size, tumor pathologic findings, presence of tumor multifocality, stage of primary disease, type of thyroid surgery, use of postoperative radioactive iodine therapy, and use of external beam radiation therapy. Filipino patients experienced a thyroid cancer recurrence rate of 25% compared with 9.5% for non-Filipino patients (odds ratio, 3.20; 95% confidence interval, 1.23-7.49; P = .004). On multivariate analysis, the increased risk of thyroid cancer recurrence persisted for Filipino patients (odds ratio, 6.99; 95% confidence interval, 2.31-21.07; P Filipino patients and non-Filipino patients regarding the rate of death from disease (5.6% vs 1.9%) and the time to recurrence (52.6 vs 53.1 months). Filipino patients have a significantly higher risk of thyroid cancer recurrence compared with non-Filipino patients. However, no significant difference was noted in the time to recurrence or the rate of death from disease. These findings justify a more aggressive initial management and follow-up regimen for Filipino patients with thyroid cancer.

Classification of breast cancer histology images using Convolutional Neural Networks.

Full Text Available Breast cancer is one of the main causes of cancer death worldwide. The diagnosis of biopsy tissue with hematoxylin and eosin stained images is non-trivial and specialists often disagree on the final diagnosis. Computer-aided Diagnosis systems contribute to reduce the cost and increase the efficiency of this process. Conventional classification approaches rely on feature extraction methods designed for a specific problem based on field-knowledge. To overcome the many difficulties of the feature-based approaches, deep learning methods are becoming important alternatives. A method for the classification of hematoxylin and eosin stained breast biopsy images using Convolutional Neural Networks (CNNs is proposed. Images are classified in four classes, normal tissue, benign lesion, in situ carcinoma and invasive carcinoma, and in two classes, carcinoma and non-carcinoma. The architecture of the network is designed to retrieve information at different scales, including both nuclei and overall tissue organization. This design allows the extension of the proposed system to whole-slide histology images. The features extracted by the CNN are also used for training a Support Vector Machine classifier. Accuracies of 77.8% for four class and 83.3% for carcinoma/non-carcinoma are achieved. The sensitivity of our method for cancer cases is 95.6%.

Full Text Available Context: Fear of cancer recurrence (FOCR is one of the most important psychological problems among cancer patients. In extensive review of related literature there were no articles on FOCR among Iranian cancer patients. Aim: The aim of present study was to investigation FOCR and its predictive factors among Iranian cancer patients. Materials and Methods: In this descriptive-correlational study 129 cancer patients participated. For data collection, the demographic checklist and short form of fear of progression questionnaire was used. Logistic regression was used to determine predictive factors of FOCR. Result: Mean score of FOCR among participants was 44.8 and about 50% of them had high level of FOCR. The most important worries of participants were about their family and the future of their children and their lesser worries were about the physical symptoms and fear of physical damage because of cancer treatments. Also, women, breast cancer patient, and patients with lower level of education have more FOCR. Discussion: There is immediate need for supportive care program designed for Iranian cancer patients aimed at decreasing their FOCR. Especially, breast cancer patients and the patient with low educational level need more attention.

Full Text Available Most cancer patients often neglect the possibility of secondary cancer. Colorectal cancer (CRC is the third leading cause of cancer death in Taiwan. It is important to be aware of the clinical characteristics of double cancer in CRC patients for early diagnosis and treatment. We retrospectively analyzed 1,031 CRC patients who underwent surgical treatment at the Department of Surgery of Kaohsiung Medical University Hospital between January 1998 and December 2004. Among these patients, CRC was accompanied by cancer of other organs in 17 patients (1.65%, either synchronously or metachronously. Therefore, we describe our experience regarding the location of CRC, the clinical symptoms and signs of these patients, the TNM stage, histology, phase, association with other malignancies, interval between cancers and clinical outcomes. Of the 17 patients in whom CRC was accompanied by primary cancer of other organs, there were four synchronous and 13 metachronous multiple cancer patients. Our patient group comprised six men and 11 women with ages ranging from 47 to 88 years (median age, 66 years. The most common location of CRC was the sigmoid colon. Six gastric cancers (35.2% and six breast cancers (35.2% were associated with primary CRC. The remaining six second primary cancers were one lung cancer, one thyroid cancer, one cervical cancer, one ovarian cancer, one skin cancer, and one urinary bladder cancer. Of the 13 metachronous multiple cancer patients, eight patients developed subsequent CRC after primary cancers of other organs, whereas two patients developed a subsequent second primary cancer after CRC. The intervals between the development of metachronous multiple cancers ranged from 2 to 19 years. In this retrospective analysis, breast and gastric cancer patients were at increased risk of developing subsequent secondary CRC. Careful attention should always be paid to the possibility of secondary CRC in treating these cancer patients. Cancer

2014-01-01

Walking is generated by the interaction between neural rhythmic and physical activities. In fact, Parkinson's disease (PD), which is an example of disease, causes not only neural rhythm generation disorders but also physical disabilities. However, the relationship between neural rhythm generation disorders and physical disabilities has not been determined. The aim of this study was to identify the mechanism of gait rhythm generation. In former research, neural rhythm generation disorders in PD patients' walking were characterized by stride intervals, which are more variable and fluctuate randomly. The variability and fluctuation property were quantified using the coefficient of variation (CV) and scaling exponent α. Conversely, because walking is a dynamic process, postural reflex disorder (PRD) is considered the best way to estimate physical disabilities in walking. Therefore, we classified the severity of PRD using CV and α. Specifically, PD patients and healthy elderly were classified into three groups: no-PRD, mild-PRD, and obvious-PRD. We compared the contributions of CV and α to the accuracy of this classification. In this study, 45 PD patients and 17 healthy elderly people walked 200 m. The severity of PRD was determined using the modified Hoehn-Yahr scale (mH-Y). People with mH-Y scores of 2.5 and 3 had mild-PRD and obvious-PRD, respectively. As a result, CV differentiated no-PRD from PRD, indicating the correlation between CV and PRD. Considering that PRD is independent of neural rhythm generation, this result suggests the existence of feedback process from physical activities to neural rhythmic activities. Moreover, α differentiated obvious-PRD from mild-PRD. Considering α reflects the intensity of interaction between factors, this result suggests the change of the interaction. Therefore, the interaction between neural rhythmic and physical activities is thought to plays an important role for gait rhythm generation. These characteristics have

Full Text Available The ischemic heart disease presents an important health problem that affects a great part of the population and is the cause of one third of all deaths in the Czech Republic. The availability of data describing the patients’ prognosis enables their further analysis, with the aim of lowering the patients’ risk, by proposing optimum treatment. The main reason for creating the neural network model is not only to automate the process of establishing the risk rate of patients suffering from ischemic heart disease, but also to adapt it for practical use in clinical conditions. Our aim is to identify especially the specific group of risk-rate patients whose well-timed preventive care can improve the quality and prolong the length of their lives.The aim of the paper is to propose a patient-parameter structure, using which we could create a suitable model based on a self-taught neural network. The emphasis is placed on identifying key descriptive parameters (in the form of a reduction of the available descriptive parameters that are crucial for identifying the required patients, and simultaneously to achieve a portability of the model among individual clinical workplaces (availability of parameters.

Malnutrition, anorexia and cachexia are a common finding in cancer patients. They become more evident with tumor growth and spread. However, the mechanisms by which they are sustained often arise early in the history of cancer. For malnutrition, these mechanisms can involve primary tumor or damage by specific treatment such as anticancer therapies (surgery, chemotherapy, radiotherapy) also in cancers that usually are not directly responsible for nutritional and metabolic status alterations (i.e. bone tumors). For anorexia, meal-related neural or hormonal signals and humoral signals related to body fat or energy storage and the interaction of these signals with the hypothalamus or the hypothalamic inappropriate response play a pathogenetic role. Some cytokines are probably involved in these mechanisms. For cachexia, the production of proinflammatory cytokines by tumour cells is the initial mechanism; the main biochemical mechanisms involved include the ubiquitine proteasome-dependent proteolysis and heat shock proteins. Treatment includes pharmaceutical and nutritional interventions. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Multi-parameter magnetic resonance imaging (mp-MRI) is increasingly popular for prostate cancer (PCa) detection and diagnosis. However, interpreting mp-MRI data which typically contains multiple unregistered 3D sequences, e.g. apparent diffusion coefficient (ADC) and T2-weighted (T2w) images, is time-consuming and demands special expertise, limiting its usage for large-scale PCa screening. Therefore, solutions to computer-aided detection of PCa in mp-MRI images are highly desirable. Most recent advances in automated methods for PCa detection employ a handcrafted feature based two-stage classification flow, i.e. voxel-level classification followed by a region-level classification. This work presents an automated PCa detection system which can concurrently identify the presence of PCa in an image and localize lesions based on deep convolutional neural network (CNN) features and a single-stage SVM classifier. Specifically, the developed co-trained CNNs consist of two parallel convolutional networks for ADC and T2w images respectively. Each network is trained using images of a single modality in a weakly-supervised manner by providing a set of prostate images with image-level labels indicating only the presence of PCa without priors of lesions' locations. Discriminative visual patterns of lesions can be learned effectively from clutters of prostate and surrounding tissues. A cancer response map with each pixel indicating the likelihood to be cancerous is explicitly generated at the last convolutional layer of the network for each modality. A new back-propagated error E is defined to enforce both optimized classification results and consistent cancer response maps for different modalities, which help capture highly representative PCa-relevant features during the CNN feature learning process. The CNN features of each modality are concatenated and fed into a SVM classifier. For images which are classified to contain cancers, non-maximum suppression and adaptive

The criteria for refraining from cardiopulmonary resuscitation in palliative care cancer patients are based on patients' right to refuse treatment and the duty of the treating personnel not to exacerbate their suffering and not to administer futile treatment. When is cardiopulmonary resuscitation futile in these patients? Systematic literature searches were conducted in PubMed for the period 1989-2010 on the results of in-hospital cardiopulmonary resuscitation in advanced cancer patients and on factors that affected the results of CPR when special mention was made of cancer. The searches yielded 333 hits and 18 included articles: four meta-analyses, eight retrospective clinical studies, and six review articles. Cancer patients had a poorer post-CPR survival than non-cancer patients. Survival declined with increasing extent of the cancer disease. Widespread and therapy-resistant cancer disease coupled with a performance status lower than WHO 2 or a PAM score (Pre-Arrest Morbidity Index) of above 8 was regarded as inconsistent with survival after cardiopulmonary resuscitation. Cardiopulmonary resuscitation is futile for in-hospital cancer patients with widespread incurable disease and poor performance status.

Objective Psychotherapy is a common non-pharmacological approach to help cancer patients in their psychological distress. The benefit of psychotherapies was documented, but the types of psychotherapies proposed are varied. Given that the previous literature review was a decade ago and no quantitative analysis was done on this topic, we again critically and systematically reviewed all published trials on psychotherapy in cancer patients. Method We identified 17 clinical trials on six types of psychotherapy for cancer patients by searching PubMed and EMBASE. Result There were four trials involved adjunct psychological therapy which were included in quantitative analysis. Each trial demonstrated that psychotherapy improved the quality of life and coping in cancer patients. There was also a reduction in distress, anxiety, and depression after a psychological intervention. However, the number and quality of clinical trials for each type of psychotherapy were poor. The meta-analysis of the four trials involved adjunct psychological therapy showed no significant change in depression, with only significant short-term improvement in anxiety but not up to a year-the standardized mean differences were -0.37 (95% confidence interval (CI) = -0.57, -0.16) at 2 months, -0.21 (95% CI = -0.42, -0.01) at 4 months, and 0.03 (95 % CI = -0.19, 0.24) at 12 months. Conclusion The evidence on the efficacy of psychotherapy in cancer patients is unsatisfactory. There is a need for more rigorous and well-designed clinical trials on this topic.

Cancer in older people is a common problem worldwide. Among various types of cancer, skin cancers represent an important percentage. The principal risk factors are sun exposure, family history of skin cancer, fair skin color, but also the age plays an important role in the genesis of skin cancers. In older people there are a more prolonged exposure to carcinogenesis and a decreased functionality of reparation mechanisms of the cells so they acquire a selective advantage of growing and proliferating. At the same time age causes alteration in immune system by increasing NK-cells absolute number and decreasing both the endogenous and the lymphokine-induced lytic activities. The anti-tumor immune response is also mediated by the cytotoxic T- lymphocytes and in the elderly a strong reduction of T-cell function has been demonstrated. In elderly patients the diagnosis and the treatment of skin cancers can be different from younger counterpart. For example in older patients with melanoma is important to evaluate Breslow depth while higher mitotic rate has major value in younger patients. Moreover, the treatment should consider the performance status of patients and their compliance.

Non-AIDS-defining cancers are a rising health concern among HIV-infected patients. Cancer screening is now an important component of health maintenance in HIV clinical practice. The decision to screen an HIV-infected patient for cancer should include an assessment of individualized risk for the particular cancer, life expectancy, and the harms and benefits associated with the screening test and its potential outcome. HIV-infected patients are at enhanced risk of several cancers compared to the general population; anal cancer, hepatocellular carcinoma, Hodgkin's lymphoma, and lung cancer all have good evidence demonstrating an enhanced risk in HIV-infected persons. A number of cancer screening interventions have shown benefit for specific cancers in the general population, but data on the application of these tests to HIV-infected persons are limited. Here we review the epidemiology and background literature relating to cancer screening interventions in HIV-infected persons. We then use these data to inform a conceptual model for evaluating HIV-infected patients for cancer screening.

To investigate the level and determinants of posttraumatic growth in Iranian cancer patients. This descriptive-correlational design study was conducted within a university-affiliated oncology hospital in Iran. A convenience sample of 450 patients with a definitive diagnosis of cancer of any type completed a demographic questionnaire and a posttraumatic growth inventory. Some disease-related information was obtained from patients' medical records. The mean of posttraumatic growth reported by participants was 76.1. There was a statistically significant association between experience of posttraumatic growth and age (r = - 0.21, P=0.001), education at university level (F = 8.9, P=0.001) and history of treatment by radiotherapy (t = 2.1, P=0.03). The findings of this study suggest that Iranian cancer patients experience a moderate to high level of posttraumatic growth and confirm the hypothesis that the level of posttraumatic growth in non-Western cancer patients is more than that of Western cancer patients. Although, assessing the reasons for this difference needs more investigations.

Automated methods for detecting clinically significant (CS) prostate cancer (PCa) in multi-parameter magnetic resonance images (mp-MRI) are of high demand. Existing methods typically employ several separate steps, each of which is optimized individually without considering the error tolerance of other steps. As a result, they could either involve unnecessary computational cost or suffer from errors accumulated over steps. In this paper, we present an automated CS PCa detection system, where all steps are optimized jointly in an end-to-end trainable deep neural network. The proposed neural network consists of concatenated subnets: 1) a novel tissue deformation network (TDN) for automated prostate detection and multimodal registration and 2) a dual-path convolutional neural network (CNN) for CS PCa detection. Three types of loss functions, i.e., classification loss, inconsistency loss, and overlap loss, are employed for optimizing all parameters of the proposed TDN and CNN. In the training phase, the two nets mutually affect each other and effectively guide registration and extraction of representative CS PCa-relevant features to achieve results with sufficient accuracy. The entire network is trained in a weakly supervised manner by providing only image-level annotations (i.e., presence/absence of PCa) without exact priors of lesions' locations. Compared with most existing systems which require supervised labels, e.g., manual delineation of PCa lesions, it is much more convenient for clinical usage. Comprehensive evaluation based on fivefold cross validation using 360 patient data demonstrates that our system achieves a high accuracy for CS PCa detection, i.e., a sensitivity of 0.6374 and 0.8978 at 0.1 and 1 false positives per normal/benign patient.

Full Text Available Detection of cancer is often equal to facing with a crisis by the patients. Traditionally it is believed that cancer diagnosis should not be told to the patients. The aim of this study was to compare the attitudes towards the disclosure of cancer diagnosis in patients with cancer and control group included healthy people. This crosssectional study was carried out in 2015 with a total of 531 people. We used three questionnaires to collect data. The first one was EORTC QLQ-C30 to assess quality of life of patients with cancer. The second one included items to assess the patients' willingness for detection of the cancer diagnosis. Finally, the third one was the DUREL to evaluate religiosity. Five hundred and thirty one subjects including 216 patients with cancer and 315 healthy people were studied. Mean age of participants was 44 ± 15.7, 50.5% were female. Overall, 63% of patien ts with cancer were informed of their disease status and 37% uninformed. A significant association was seen between the awareness of cancer with physical and social functioning of quality of life. There was a positive significant association between the tendency for being informed of the diagnosis and non-organizational religious activity in participants without cancer. Global health status and all dimensions of religious were correlated in patients significantly. We found the majority of subjects tend to be aware of the disclosure of diagnosis. The physical and social functioning of quality of life were better in uninformed patients than informed 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

Atomic Force Microscopy (AFM) has the unique capability of probing the nanoscale mechanical properties of biological systems that affect and are affected by the occurrence of many pathologies, including cancer. This capability has triggered growing interest in the translational process of AFM from physics laboratories to clinical practice. A factor still hindering the current use of AFM in diagnostics is related to the complexity of AFM data analysis, which is time-consuming and needs highly specialized personnel with a strong physical and mathematical background. In this work, we demonstrate an operator-independent neural-network approach for the analysis of surgically removed brain cancer tissues. This approach allowed us to distinguish—in a fully automated fashion—cancer from healthy tissues with high accuracy, also highlighting the presence and the location of infiltrating tumor cells.

This paper shows the concurrent use of thermography and artificial neural networks (ANN) for the diagnosis of breast cancer, a disease that is growing in prominence in women all over the world. It has been reported that breast thermography itself could detect breast cancer up to 10 years earlier than the conventional golden methods such as mammography, in particular in the younger patient. However, the accuracy of thermography is dependent on many factors such as the symmetry of the breasts' temperature and temperature stability. A woman's body temperature is known to be stable in certain periods after menstruation and it was found that the accuracy of thermography in women whose thermal images are taken in a suitable period (5th - 12th and 21st day of menstruation) is higher (80%) than the total population of patients (73%). The stability of the body temperature will depend on physiological state. This paper examines the use of ANN to complement the infrared heat radiating from the surface of the body with other physiological data. Four backpropagation neural networks were developed and trained using the results from the Singapore General Hospital patients' physiological data and thermographs. Owing to the inaccuracies found in thermography and the low population size gathered for this project, the networks developed could only accurately diagnose about 61.54% of the breast cancer cases. Nevertheless, the basic neural network framework has been established and it has great potential for future development of an intelligent breast cancer diagnosis system. This would be especially useful to the teenagers and young adults who are unsuitable for mammography at a young age. An intelligent breast thermography-neural network will be able to give an accurate diagnosis of breast cancer and can make a positive impact on breast disease detection.

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.

The objective of the study is to provide some implications for rehabilitation of hearing impairment by investigating changes of neural activities of directional brain networks in patients with long-term bilateral hearing loss. Firstly, we implemented neuropsychological tests of 21 subjects (11 patients with long-term bilateral hearing loss, and 10 subjects with normal hearing), and these tests revealed significant differences between the deaf group and the controls. Then we constructed the individual specific virtual brain based on functional magnetic resonance data of participants by utilizing effective connectivity and multivariate regression methods. We exerted the stimulating signal to the primary auditory cortices of the virtual brain and observed the brain region activations. We found that patients with long-term bilateral hearing loss presented weaker brain region activations in the auditory and language networks, but enhanced neural activities in the default mode network as compared with normally hearing subjects. Especially, the right cerebral hemisphere presented more changes than the left. Additionally, weaker neural activities in the primary auditor cortices were also strongly associated with poorer cognitive performance. Finally, causal analysis revealed several interactional circuits among activated brain regions, and these interregional causal interactions implied that abnormal neural activities of the directional brain networks in the deaf patients impacted cognitive function.

In this paper, we consider spatial operation median filter to reduce the noise in the cervical images yielded by colposcopy tool. The backpropagation neural network (BPNN) model is applied to the colposcopy images to classify cervical cancer. The classification process requires an image extraction by using a gray level co-occurrence matrix (GLCM) method to obtain image features that are used as inputs of BPNN model. The advantage of noise reduction is evaluated by comparing the performances of BPNN models with and without spatial operation median filter. The experimental result shows that the spatial operation median filter can improve the accuracy of the BPNN model for cervical cancer classification.

This review integrates neuroimaging studies of 2 domains of social cognition--emotion comprehension and theory of mind (ToM)--in patients with major depressive disorder and bipolar disorder. The influence of key clinical and method variables on patterns of neural activation during social cognitive processing is also examined. Studies were identified using PsycINFO and PubMed (January 1967 to May 2011). The search terms were "fMRI," "emotion comprehension," "emotion perception," "affect comprehension," "affect perception," "facial expression," "prosody," "theory of mind," "mentalizing" and "empathy" in combination with "major depressive disorder," "bipolar disorder," "major depression," "unipolar depression," "clinical depression" and "mania." Taken together, neuroimaging studies of social cognition in patients with mood disorders reveal enhanced activation in limbic and emotion-related structures and attenuated activity within frontal regions associated with emotion regulation and higher cognitive functions. These results reveal an overall lack of inhibition by higher-order cognitive structures on limbic and emotion-related structures during social cognitive processing in patients with mood disorders. Critically, key variables, including illness burden, symptom severity, comorbidity, medication status and cognitive load may moderate this pattern of neural activation. Studies that did not include control tasks or a comparator group were included in this review. Further work is needed to examine the contribution of key moderator variables and to further elucidate the neural networks underlying altered social cognition in patients with mood disorders. The neural networks under lying higher-order social cognitive processes, including empathy, remain unexplored in patients with mood disorders.

Ovarian cancer is one of the most common gynecologic malignancies. Accurate classification of ovarian cancer types (serous carcinoma, mucous carcinoma, endometrioid carcinoma, transparent cell carcinoma) is an essential part in the different diagnosis. Computer-aided diagnosis (CADx) can provide useful advice for pathologists to determine the diagnosis correctly. In our study, we employed a Deep Convolutional Neural Networks (DCNN) based on AlexNet to automatically classify the different types of ovarian cancers from cytological images. The DCNN consists of five convolutional layers, three max pooling layers, and two full reconnect layers. Then we trained the model by two group input data separately, one was original image data and the other one was augmented image data including image enhancement and image rotation. The testing results are obtained by the method of 10-fold cross-validation, showing that the accuracy of classification models has been improved from 72.76 to 78.20% by using augmented images as training data. The developed scheme was useful for classifying ovarian cancers from cytological images. © 2018 The Author(s).

Introduction: The utilization of the post-traumatic stress disorder (PTSD) diagnostic spectrum is currently being debated to categorize psychological adjustment in cancer patients. The aims of this study were to: (1) evaluate the presence of cancer-related traumatic dissociative symptomatology in a sample of cancer patients; (2) examine the correlation of cancer-related dissociation and sociodemographic and medical variables, anxiety, depression, and post-traumatic stress symptomatology; (3) investigate the predictors of cancer-related dissociation. Methods: Ninety-two mixed cancer patients (mean age: 58.94, ds = 10.13) recruited from two hospitals in northern Italy were administered a questionnaire on sociodemographic and medical characteristics, the Karnofsky Scale to measure the level of patient activity and medical care requirements, the Hospital Anxiety and Depression Scale (HADS) to evaluate the presence of anxiety and depression, the Impact of Event Scale Revised (IES-R) to assess the severity of intrusion, avoidance, and hypervigilance, and the Peritraumatic Dissociative Experiences Questionnaire (PDEQ) to quantify the traumatic dissociative symptomatology. Results: 31.5% of participants report a PDEQ score above the cutoff. The results indicated that dissociative symptomatology was positively correlated with HADS scores (HADS-Anxiety: r = 0.476, p dissociative symptomatology. The results converged on a three predictor model revealing that IES-R-Intrusion, IES-R-Avoidance, and IES-R-Hyperarousal accounted for 53.9% of the explained variance. Conclusion: These findings allow us to hypothesize a specific psychological reaction which may be ascribed to the traumatic spectrum within the context of cancer, emphasizing the close relationship between the origin of dissociative constituents which, according to the scientific literature, compose the traumatic experience. Our results have implications for understanding dissociative symptomatology in a cancer

Liver cancer is the second leading cause of cancer-related death worldwide.1 Hepatocellular carcinoma (HCC) is the most common primary liver cancer accounting for approximately 80% of cases. Intrahepatic cholangiocarcinoma (ICC) is a rare liver cancer, arising in patients with the same risk factors as HCC, but treatment options and prognosis differ. The diagnosis of HCC is based primarily on imaging but distinguishing between HCC and ICC is challenging due to common radiographic features.2-4 The aim of the present study is to classify HCC and ICC in portal venous phase CT. 107 patients with resected ICC and 116 patients with resected HCC were included in our analysis. We developed a deep neural network by modifying a pre-trained Inception network by retraining the final layers. The proposed method achieved the best accuracy and area under the receiver operating characteristics curve of 69.70% and 0.72, respectively on the test data.

The presence of gastrointestinal (GI) cancer and its treatment might aggravate patient nutritional status. Malnutrition is one of the major factors affecting the postoperative course. We evaluated changes in perioperative nutritional status and risk factors of postoperative severe malnutrition in the GI cancer patients. Nutritional status was prospectively evaluated using patient-generated subjective global assessment (PG-SGA) perioperatively between May and September 2011. A total of 435 patients were enrolled. Among them, 279 patients had been diagnosed with gastric cancer and 156 with colorectal cancer. Minimal invasive surgery was performed in 225 patients. PG-SGA score increased from 4.5 preoperatively to 10.6 postoperatively (pgastric cancer patients, postoperative severe malnourishment increased significantly (p60, pgastric cancer (pgastric cancer, and open surgery remained significant as risk factors of severe malnutrition. The prevalence of severe malnutrition among GI cancer patients in this study increased from 2.3% preoperatively to 26.3% after an operation. Old age, preoperative weight loss, gastric cancer, and open surgery were shown to be risk factors of postoperative severe malnutrition. In patients at high risk of postoperative severe malnutrition, adequate nutritional support should be considered.

Acute kidney injury (AKI) is a frequent and significant complication of cancer and cancer therapy. Cancer patients frequently encounter risk factors for AKI including older age, CKD, prerenal conditions, sepsis, exposure to nephrotoxins, and obstructive physiology. AKI can also be secondary to paraneoplastic conditions, including glomerulonephritis and microangiopathic processes. This complication can have significant consequences, including effects on patients' ability to continue to receive therapy for their malignancy. This review will serve to summarize potential etiologies of AKI that present in patients with cancer as well as to highlight specific patient populations, such as the critically ill cancer patient.

2015-01-01

Interpretation of gait data obtained from modern 3D gait analysis is a challenging and time consuming task. The aim of this study was to create neural network models which can recognise the gait patterns from pre- and post-treatment and the normal ones. Neural network is a method which works on the principle of learning from experience and then uses the obtained knowledge to predict the unknown. Methods: Twenty-eight patients with cerebral palsy were recruited as subjects whose gait was analysed in pre- and post-treatment. A group of twenty-six normal subjects also participated in this study as control group. All subjects gait was analysed using Vicon Nexus to obtain the gait parameters and kinetic and kinematic parameters of hip, knee and ankle joints in three planes of both limbs. The gait data was used as input to create neural network models. A total of approximately 300 trials were split into 70% and 30% to train and test the models, respectively. Different models were built using different parameters. The gait was categorised as three patterns, i.e., normal, pre- and post-treatments. Result: The results showed that the models using all parameters or using the joint angles and moments could predict the gait patterns with approximately 95% accuracy. Some of the models e.g., the models using joint power and moments, had lower rate in recognition of gait patterns with approximately 70-90% successful ratio. Conclusion: Neural network model can be used in clinical practice to recognise the gait pattern for cerebral palsy patients. (author)

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.

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.

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.

Full Text Available The objective of this work is to verify the incidence of incidental prostate adenocarcinoma in patients who underwent radical cystoprostatectomy for invasive bladder carcinoma. We have retrospectively reviewed patients who underwent radical cystoprostatectomy for infiltrative bladder tumors in period between 2003 and 2007 year, 94 men with bladder cancer underwent radical cystoprostatectomy at Urology Clinic-University of Sarajevo Clinics Centre. Mean age of patients was 67 years, with age limits ranging between 48 and 79 years. Pathohystological evaluation was used for all specimens from RCP. We found that 9,57% of cystoprostatectomy specimens in patients with bladder cancer also contained incidental prostate cancer. This result was much lower than overall mean frequency of incidentally detected prostate cancer in other series of cystoprostatectomy cases (range, 23%-68%. In conclusion we recommended digital rectal examination (DRE and prostate-specific antigen (PSA test as part of the bladder cancer work up and complete removal of the prostate at cystoprostatectomy to prevent residual prostate cancer.

Previous studies have noted a possible association between periodontal diseases and the risk of various cancers. We assessed cancer risk in a cohort of patients with moderate to severe periodontitis. Patients diagnosed with moderate to severe periodontitis by a periodontist between 2001 and 2010 were identified from the hospital registry. Patients younger than 35 years of age or with a prior cancer diagnosis were excluded. The age- and gender-standardized incidence rates (SIR) were calculated by dividing the number of observed cases by the number of expected cases from Turkish National Cancer Registry 2013 data. A total of 280 patients were included (median age 49.6, 54% female). Median follow-up was 12 years. Twenty-five new cancer cases were observed. Patients with periodontitis had 77% increased risk of cancer (SIR 1.77, 95% CI 1.17-2.58, p = .004). Women with periodontitis had significantly higher risk of breast cancer (SIR 2.40, 95% CI 0.88-5.33) and men with periodontitis had significantly higher risk of prostate cancer (SIR 3.75, 95% CI 0.95-10.21) and hematological cancers (SIR 6.97, 95% CI 1.77-18.98). Although showing a causal association necessitates further investigation, our results support the idea that periodontitis might be associated with increased cancer risk, particularly with hematological, breast and prostate cancers.

Background. The aim of this review is to present common psychosocial problems in cancer patients and their possible coping strategies. 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.

Overview on Patient Centricity in Cancer Care

Directory of Open Access Journals (Sweden)

Šarunas Narbutas

2017-10-01

Full Text Available Successful implementation of treatment in cancer care partially depends on how patients' perspectives are taken into account, as preferences of health care professionals and patients may differ. Objectives of this exploratory research were (I to identify patient preferences and values (PPVs in cancer care as indicated by patient organizations (POs, (II to determine how these PPVs are captured in cancer care guidelines and (III to review how guidelines take into account these PPVs. Based on a survey developed and completed by 19 POs, a literature review was conducted to analyse how patient perspectives are incorporated in oncology treatment guidelines. Based on survey results traditional health technology assessment value propositions of oncology care, such as extended life, treatment-free remission and pain reduction, were also highly rated by POs. However, the heterogeneity of cancer PPVs were clearly reflected in the survey results. PPVs in cancer care guidelines were mostly limited to those micro-level aspects that are strictly related to health care provision, such as side-effects and comorbidities. Patient experience, emotional support and convenience of care were relatively neglected fields in the reviewed guidelines. Patient engagement was rarely presented in the guideline development phase. POs believe that patients should be encouraged to take an active role in their own care due to the heterogeneity of cancer patients and PPVs. Even if patient-centricity is a leading paradigm in cancer policy, based on our research it is not yet standard practice to include patients or POs at all appropriate levels of decision-making processes that are related to their health and well-being. Patient engagement should be an integral part of cancer care decision-making. This complexity must be reflected throughout policy making, avoiding a population level “one-size-fits-all” solution.

2006-08-01

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

In England, 'fast-track' (also known as 'two-week wait') general practitioner referrals for suspected cancer in symptomatic patients are used to shorten diagnostic intervals and are supported by clinical guidelines. However, the use of the fast-track pathway may vary for different patient groups. We examined data from 669 220 patients with 35 cancers diagnosed in 2006-2010 following either fast-track or 'routine' primary-to-secondary care referrals using 'Routes to Diagnosis' data. We estimated the proportion of fast-track referrals by sociodemographic characteristic and cancer site and used logistic regression to estimate respective crude and adjusted odds ratios. We additionally explored whether sociodemographic associations varied by cancer. There were large variations in the odds of fast-track referral by cancer (P<0.001). Patients with testicular and breast cancer were most likely to have been diagnosed after a fast-track referral (adjusted odds ratios 2.73 and 2.35, respectively, using rectal cancer as reference); whereas patients with brain cancer and leukaemias least likely (adjusted odds ratios 0.05 and 0.09, respectively, for brain cancer and acute myeloid leukaemia). There were sex, age and deprivation differences in the odds of fast-track referral (P<0.013) that varied in their size and direction for patients with different cancers (P<0.001). For example, fast-track referrals were least likely in younger women with endometrial cancer and in older men with testicular cancer. Fast-track referrals are less likely for cancers characterised by nonspecific presenting symptoms and patients belonging to low cancer incidence demographic groups. Interventions beyond clinical guidelines for 'alarm' symptoms are needed to improve diagnostic timeliness.

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

The total number of malignant neoplasms included in this study 15,737 cases(11.8%) among 133,251 cases for 3 years. On sex, females with 52.9% were much more than males with 47.1%. The highest proportion of cancer patients by age was 33.7% in males and 28.5% in females, respectivelty for 50-59 age group. The most frequent primary site among males was found to be stomach with 35.5%, followed by liver(14.7%), lung(13.0%), esophagus(5.4%) and colon (3.2%). In females, the first order was uterine cervix with 40.6%, followed by stomach(17.2%), breast(14.4), rectum(3.7%) and lung(3.4%). The most common type of morphology of malignant neoplasms was adenocarcinoma(47.4%) in males an squamous cell carcinoma(58.0%) in females. Among the cancer patients initially diagnosed in this hospital, the proportion of malignant neoplasms by the exent of disease was 2.5% for patient with carcinoma-in-situ, 54.1% for patients with localized involvement, 13.3% for patients with regional involvement and 8.5% for patients with distant involvement. Among the cancer patients initially treatment in this hospital, the proportion of malignant neoplasms by the method of treatment was 23.6% for surgery, 25.3% for radiotherapy and 30.3% for chemotherapy. Among the cancer patients confirmed by medical records, 7.7% was traced more than 5 years. (Author)

We present a retrospective case series of patients with hyperthyroidism and thyroid cancer. Our goal was to look at their clinical characteristics and outcomes to determine which patients would require further investigation. We reviewed the case notes of all patients with a histopathologic diagnosis of thyroid cancer and biochemical evidence of hyperthyroidism who had been treated at a thyroid cancer center from January 2006 through October 2013. During that time, 66 patients had been diagnosed with thyroid cancer. Of these, 8 patients (12%)-all women, aged 29 to 87 years (mean: 55.6; median: 50.5)-had biochemical evidence of hyperthyroidism. Among these 8 patients, 4 had an autonomously functioning toxic nodule (AFTN), 3 were diagnosed with Graves disease, and 1 had a toxic multinodular goiter. Five patients had suspicious features on preoperative ultrasonography. All 8 patients were diagnosed with the papillary type of thyroid carcinoma. The mean size of the tumor in the 4 patients with AFTN was significantly larger than it was in those with Graves disease (42.3 ± 23.8 mm vs. 3.8 ± 1.6; p = 0.04). The 3 patients with Graves disease all had incidentally found papillary microcarcinoma. Between these two groups, the patients with AFTN had a poorer prognosis; 2 of them had extracapsular invasion and lymph node metastasis, and another died of her disease. We found that the incidence of hyperthyroidism in thyroid cancer patients was relatively high (12%). In contrast to what has previously been reported in the literature, patients with AFTN seem to have more aggressive disease and poorer outcomes than do patients with Graves disease. Any suspicious nodule associated with hyperthyroidism should be evaluated carefully.

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

Racial and ethnic minorities as well as other vulnerable populations experience disparate cancer-related health outcomes. Patient navigation is an emerging health care delivery innovation that offers promise in improving quality of cancer care delivery to these patients who experience unique health-access barriers. Metrics are needed to evaluate whether patient navigation can improve quality of care delivery, health outcomes, and overall value in health care during diagnosis and treatment of cancer. Information regarding the current state of the science examining patient navigation interventions was gathered via search of the published scientific literature. A focus group of providers, patient navigators, and health-policy experts was convened as part of the Patient Navigation Leadership Summit sponsored by the American Cancer Society. Key metrics were identified for assessing the efficacy of patient navigation in cancer diagnosis and treatment. Patient navigation data exist for all stages of cancer care; however, the literature is more robust for its implementation during prevention, screening, and early diagnostic workup of cancer. Relatively fewer data are reported for outcomes and efficacy of patient navigation during cancer treatment. Metrics are proposed for a policy-relevant research agenda to evaluate the efficacy of patient navigation in cancer diagnosis and treatment. Patient navigation is understudied with respect to its use in cancer diagnosis and treatment. Core metrics are defined to evaluate its efficacy in improving outcomes and mitigating health-access barriers. Copyright © 2011 American Cancer Society.

Purpose: Isocitrate dehydrogenase ( IDH ) mutations in glioma patients confer longer survival and may guide treatment decision making. We aimed to predict the IDH status of gliomas from MR imaging by applying a residual convolutional neural network to preoperative radiographic data. Experimental Design: Preoperative imaging was acquired for 201 patients from the Hospital of University of Pennsylvania (HUP), 157 patients from Brigham and Women's Hospital (BWH), and 138 patients from The Cancer Imaging Archive (TCIA) and divided into training, validation, and testing sets. We trained a residual convolutional neural network for each MR sequence (FLAIR, T2, T1 precontrast, and T1 postcontrast) and built a predictive model from the outputs. To increase the size of the training set and prevent overfitting, we augmented the training set images by introducing random rotations, translations, flips, shearing, and zooming. Results: With our neural network model, we achieved IDH prediction accuracies of 82.8% (AUC = 0.90), 83.0% (AUC = 0.93), and 85.7% (AUC = 0.94) within training, validation, and testing sets, respectively. When age at diagnosis was incorporated into the model, the training, validation, and testing accuracies increased to 87.3% (AUC = 0.93), 87.6% (AUC = 0.95), and 89.1% (AUC = 0.95), respectively. Conclusions: We developed a deep learning technique to noninvasively predict IDH genotype in grade II-IV glioma using conventional MR imaging using a multi-institutional data set.

2010-01-01

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

Breast cancer survivors can be expected to suffer from menopause symptoms with estrogen deprivation due to cancer treatments, in addition to natural menopause-related estrogen loss. To gain an understanding of what support breast cancer patients have when they suffer from menopausal symptoms, and utilize findings to further inform National Health Service (NHS) care provision for breast cancer survivors. Qualitative study with focus group sessions targeting Caucasian and Asian women with breast cancer. Patient stories, with women describing their breast cancer journey and speaking about support received for any menopausal symptoms. Thematic data analysis of transcription. Breast cancer patients were not sure if they had menopausal symptoms or whether this was due to their breast cancer condition or treatment. Patients had an attitude of acceptance of menopausal symptoms and reported trying to cope with these by themselves. This research identifies a need for more information that is culturally sensitive on managing menopause symptoms, both as side-effects of breast cancer treatments as well as for affect on quality of life during the survivorship phase. Our work also gives insight into cultural remedies used for hot flushes by Asian patients, which they consider as 'cooling' foods. Breast cancer patients want to know whether side-effects of cancer treatment persist long term and how these can be managed. There is a need for improved patient support within any new NHS service models that are developed along breast cancer patient pathways, and inclusion of personalized advice for menopause symptoms.

In order to assess the impact of cancer diagnosis on several psychological dimensions, this study was undertaken with the aim to understand, identify and document the psychological responses of cancer patients - their common thoughts, feelings, body sensations and behavior when they faced the cancer diagnosis. The sample consisted of 80 patients who attended psychological lectures during the implementation of the European Educational Programme (EEP) "Learning to live with cancer". At the beginning of the lectures, the patients were asked to fulfill the self-describing questionnaire with 4 open questions: "Describe your common thoughts, feelings, behavior, and body reactions in the first 6 weeks when you learned that you were affected by cancer". A significant proportion of patients reported disease denial (65%) and reexamination in relation to past life experiences, stressful events and bad habits (60%). Depressive feelings and disappointment were reported by 90% of the patients, while 85% of them reported fear, hopelessness and emptiness. They also reported sadness (70%), anger and anxiety (65%), nervousness and irritability (90%). Positive thoughts and attitude in the sense of optimism concerning a successful treatment outcome were reported by 20% and 15% of patients, respectively. The diagnosis of cancer and cancer treatment can cause distress, emotional turmoil and different psychosocial disorders. Taking into consideration different psychological reactions of cancer patients can be helpful for organizing adequate psycho-educational and psychosocial support, and psychotherapy for cancer patients and their families.

To explore patients' and family members' views on communication during cancer care and to identify those aspects of clinician-patient communication which were most important to patients and family members. We conducted a secondary data analysis of qualitative data from 137 patients with cancer and family members of patients with cancer. We used a modified version of the constant comparative method and coding paradigm of grounded theory. Patients want sensitive, caring clinicians who provide information that they need, when they need it, in a way that they can understand; who listen and respond to questions and concerns, and who attempt to understand the patient's experience. Effective information exchange and a positive interpersonal relationship with the clinician were of fundamental importance to patients and family members. These were interrelated; for instance, failure to provide information a patient needed could damage the relationship, whereas excellent listening could foster the relationship. Information exchange and relationship were also integral to decision-making, managing uncertainty, responding to emotions, and self-management. Clinicians who were responsive to patients' needs beyond the immediate medical encounter were valued. The complexity of cancer care today suggests that efforts to improve communication must be multilevel, acknowledging and addressing patient, clinician, organizational and policy barriers, and facilitators. Measurement tools are needed to assess cancer patients' and family members' experiences with communication over the course of cancer care to provide meaningful, actionable feedback to those seeking to optimize their effectiveness in communicating with patients with cancer.

Esophageal cancer patients are often associated with multiple primary cancers (MPC). The aim of this study is to evaluate the effect of MPC on prognosis in esophageal cancer patients treated by radiotherapy. Between 2001 and 2008, esophageal cancer patients treated by definitive radiotherapy at Gunma Cancer Center were retrospectively reviewed. Exclusion criteria were preoperative or postoperative radiotherapy, palliative radiotherapy, follow-up of <6 months, radiation dose of <50 Gy and no information on MPC. We analyzed 167 esophageal cancer patients and 56 (33.5%) were associated with MPC. Gastric cancer was the most frequent tumor (38.2%), followed by head and neck cancer (26.5%). Median follow-up time was 31.5 months (range 6.1-87.3 months). Patients with MPC included more stage I/II esophageal cancer than those without MPC (66.1% vs. 36.9%, P<0.01). The 5-year overall survival rate for esophageal cancer with MPC was relatively better than those without MPC (46.1% vs. 26.7%), although the difference did not reach statistical significance in univariate analysis (P=0.09). Stage I/II esophageal cancer patients had a significantly better overall survival than stage III/IV patients (P<0.01). Among esophageal cancer patients with MPC, there was no difference in overall survival between antecedent and synchronous cancer (P=0.59). Our study indicated that the prognosis of esophageal cancer patients treated by radiotherapy was primarily determined by the clinical stage itself, but not the presence of MPC. (author)

Palliative care has been increasingly recognized as an important part of cancer care but remains underutilized in patients with solid cancers. There is a current gap in knowledge regarding why palliative care is underutilized nationwide. To identify the factors associated with palliative care use among deceased patients with solid cancer tumors. Using the 2016 National Cancer Data Base, we identified deceased patients (2004-2013) with breast, colon, lung, melanoma, and prostate cancer. Data were described as percentages. Associations between palliative care use and patient, facility, and geographic characteristics were evaluated through multivariate logistic regression. A total of 1 840 111 patients were analyzed; 9.6% received palliative care. Palliative care use was higher in the following patient groups: survival >24 months (17% vs 2%), male (54% vs 46%), higher Charlson-Deyo comorbidity score (16% vs 8%), treatment at designated cancer programs (74% vs 71%), lung cancer (76% vs 28%), higher grade cancer (53% vs 24%), and stage IV cancer (59% vs 13%). Patients who lived in communities with a greater percentage of high school degrees had higher odds of receiving palliative care; Central and Pacific regions of the United States had lower odds of palliative care use than the East Coast. Patients with colon, melanoma, or prostate cancer had lower odds of palliative care than patients with breast cancer, whereas those with lung cancer had higher odds. Palliative care use in solid cancer tumors is variable, with a preference for patients with lung cancer, younger age, known insurance status, and higher educational level.

The inspection of live excised tissue specimens to ascertain malignancy is a challenging task in dermatopathology and generally in histopathology. We introduce a portable desktop prototype device that provides highly accurate neural network classification of malignant and benign tissue. The handheld device collects 47 impedance data samples from 1 Hz to 32 MHz via tetrapolar blackened platinum electrodes. The data analysis was implemented with six different backpropagation neural networks (BNN). A data set consisting of 180 malignant and 180 benign breast tissue data files in an approved IRB study at the Aurora Medical Center, Milwaukee, WI, USA, were utilized as a neural network input. The BNN structure consisted of a multi-tiered consensus approach autonomously selecting four of six neural networks to determine a malignant or benign classification. The BNN analysis was then compared with the histology results with consistent sensitivity of 100% and a specificity of 100%. This implementation successfully relied solely on statistical variation between the benign and malignant impedance data and intricate neural network configuration. This device and BNN implementation provides a novel approach that could be a valuable tool to augment current medical practice assessment of the health of breast, squamous, and basal cell carcinoma and other excised tissue without requisite tissue specimen expertise. It has the potential to provide clinical management personnel with a fast non-invasive accurate assessment of biopsied or sectioned excised tissue in various clinical settings.

Cancer patient navigation (PN) programs have been shown to increase access to and utilization of cancer care for poor and underserved individuals. Despite mounting evidence of its value, cancer patient navigation is not universally understood or provided. We describe five PN programs and the range of tasks their navigators provide across the cancer care continuum (education and outreach, screening, diagnosis and staging, treatment, survivorship, and end-of-life). Tasks are organized by their potential to make cancer services understandable, available, accessible, affordable, appropriate, and accountable. Although navigators perform similar tasks across the five programs, their specific approaches reflect differences in community culture, context, program setting, and funding. Task lists can inform the development of programs, job descriptions, training, and evaluation. They also may be useful in the move to certify navigators and establish mechanisms for reimbursement for navigation services. PMID:22423178

Several studies have suggested that patients with acromegaly have an increased risk of thyroid, colorectal, breast and prostate cancers. In this study we determined the prevalence of malignant neoplasms in patients with acromegaly. Cancer risk was evaluated in a cohort of 110 patients (M/F 48/62, age 58.63±13.8 years, range 30-86) with acromegaly. Mean age at diagnosis of acromegaly was 46.37±13.11 years. Mean period of time since diagnosis of acromegaly was 12.26+9.6 years. From 110 patients, cancer was diagnosed in 26 (23.6%) patients. Thyroid cancer was the most common cancer and was diagnosed in 13 patients (11.8%); other cancers encountered were gastric cancer (N=2), endometrial cancer (N-2), and breast cancer, colon cancer, prostate cancer (N-2), myelodysplastic syndrome, renal cell carcinoma, lung cancer and pancreatic carcinoma, one case each. Age, gender, age at the time of diagnosis of acromegaly, tumor size of pituitary adenoma and duration of disease were not associated with cancer development. This study suggests that patients with acromegaly have an increased risk of thyroid cancer and therefore they should undergo regular screening with hormonal and ultrasound evaluation of the thyroid and FNAB when required.

Psychological aspects of cancer patients

Directory of Open Access Journals (Sweden)

Graça Cardoso

2014-06-01

Full Text Available Cancer is accompanied by important psychological distress experienced by both patient and family. From the moment of the diagnosis on, the patient has to develop a great number of mechanisms and tasks of adjustment to the illness and its circumstances. The high prevalence of anxiety and depressive disorders during the course of cancer increases in the end stage disea‐ se. Therefore, a global plan of intervention integrating somatic and psychological/ psychiatric care throughout all the phases of the illness is crucial in the treatment of these patients. Health professionals working on this field can also experience emotional reactions to their patients’ suffering. They should be aware of the emotional aspects involved and develop training to help them intervene adequately with the patient and the family. The articulation between oncologists, palliative care professionals, and mental health care teams can be of great help in providing good quality of care to cancer patients.

Family caregiver burden: the burden of caring for lung cancer patients according to the cancer stage and patient quality of life

Full Text Available ABSTRACT Objective: Patients with lung cancer experience different feelings and reactions, based on their family, social, cultural, and religious backgrounds, which are a source of great distress, not only for the patients but also for their family caregivers. This study aimed to evaluate the impact that lung cancer stage and quality of life (QoL of lung cancer patients have on caregiver burden. Methods: This was a prospective cross-sectional study. Consecutive patient-caregiver dyads were selected and asked to complete the Hospital Anxiety and Depression Scale and the Medical Outcomes Study 36-item ShortForm Health Survey (SF-36. Family caregivers also completed the Caregiver Burden Scale. Group-based modeling was used in order to identify patients with early- or advanced-stage cancer (IA to IIIA vs. IIIB to IV plus non-impaired or impaired QoL (SF36 total score > 50 vs. ≤ 50. Patient-caregiver dyads were stratified into four groups: early-stage cancer+non-impaired QoL; advanced-stage cancer+non-impaired QoL; early-stage cancer+impaired QoL; and advanced-stage cancer+impaired QoL. Results: We included 91 patient-caregiver dyads. The majority of the patients were male and heavy smokers. Family caregivers were younger and predominantly female. The burden, QoL, level of anxiety, and level of depression of caregivers were more affected by the QoL of the patients than by their lung cancer stage. The family caregivers of the patients with impaired QoL showed a higher median burden than did those of the patients with non-impaired QoL, regardless of disease stage. Conclusions: Caregiver burden is more affected by patient QoL than by lung cancer stage.

Beyond age and comorbidity, functionality can shape the long-term survival potential of patients with cancer. Accordingly, herein the authors compared mortality and receipt of cancer-directed surgery according to patient function among older adults with kidney cancer. Using Surveillance, Epidemiology, and End Results (SEER)-Medicare data from 2000 through 2009, the authors studied 28,326 elderly subjects with primary kidney cancer. Patient function was quantified using function-related indicators, claims indicative of dysfunction and disability. Adjusting for patient and cancer characteristics, competing risk regression was used to assess the relationship between function-related indicator count and cause-specific mortality and then generalized estimating equations were used to quantify the probability of surgery. A total of 13,619 adult patients (48.1%) with at least 1 function-related indicator were identified. A higher indicator category was associated with older age, greater comorbidity, female sex, unmarried status, lower socioeconomic status, and higher stage of disease (Pkidney cancer mortality varied minimally with patient function. Patients with ≥ 2 indicators received cancer-directed surgery less often than those without disability (odds ratio, 0.61; 95% CI, 0.56-0.66), although treatment probabilities remained high for patients with locoregional disease and low for those with metastatic cancer. Among older adults with kidney cancer, functional health stands as a significant predictor of long-term survival. However, receipt of cancer-directed surgery appears largely determined by cancer stage. Patient function should be considered more heavily when determining treatment for older adults with kidney cancer.

To analyze patients with kidney cancer referred for evaluation at a high-volume genetics service at a comprehensive cancer center and identify factors associated with positive tests for hereditary cancer syndromes. A retrospective review of patients referred to the Clinical Genetics Service at Memorial Sloan-Kettering Cancer Center was performed, and patients with a personal history of kidney cancer were identified. Patient and disease characteristics were reviewed. In all, 4 variables including age at diagnosis of kidney tumor, presence of syndromic manifestations, family history of kidney cancer, and number of primary malignancies were evaluated for association with positive test results in 2 groups: patients tested for renal cell carcinoma syndromes and Lynch syndrome. Guidance for genetic testing strategy in patients with kidney cancer is provided. Between 1999 and 2012, 120 patients with a history of kidney cancer were evaluated by the Clinical Genetics Service. The mean age at kidney cancer diagnosis was 52 years (interquartile range: 42-63), with 57% being women. A family history of kidney cancer was reported by 39 patients (33%). Time between diagnosis of first cancer and genetic consultation was 5 years in the remaining 23%. Overall, 95 patients were tested for genetic abnormalities with 27 (28%) testing positive. Testing for renal cell carcinoma (RCC)-related syndromes was performed on 43 patients, with 13 testing positive (30%). Lynch syndrome testing was positive in 9 patients (32%) after 28 were tested. In RCC-associated syndromes, young age of diagnosis was associated with positive test results. Conversely, syndromic manifestations and increasing number of primary malignancies were associated with positive Lynch testing. The discovery of inherited kidney cancer syndromes has provided a unique opportunity to identify patients at increased risk for cancer. Factors associated with positive genetic testing are unique to different syndromes. These data

There is an increased attention to and demand for patient empowerment in cancer treatment and follow-up programs. Patient empowerment has been defined as feeling in control of or having mastery in relation to cancer and cancer care. This calls for properly developed questionnaires assessing empowerment from the user perspective. The aim of this review was to identify questionnaires and subscales measuring empowerment and manifestations of empowerment among cancer patients. We conducted a systematic search of the PubMed, PsycINFO and CINAHL databases. Empowerment and multiple search terms associated with empowerment were included. We included peer-reviewed articles published in English, which described questionnaires measuring empowerment or manifestations of empowerment in a cancer setting. In addition, the questionnaire had to be a patient-reported outcome measure for adult cancer patients. Database searches identified 831 records. Title and abstract screening resulted in 482 records being excluded. The remaining 349 full text articles were retrieved and assessed for eligibility. This led to the inclusion of 33 individual instruments measuring empowerment and manifestations of empowerment. Of these, only four were specifically developed to measure empowerment, and two were originally developed for the cancer setting, whereas the remaining two were developed elsewhere, but adapted to the cancer setting. The other 29 questionnaires were not intended to measure the concept of empowerment, but focused on patient-centered care, patient competence, self-efficacy, etc. However, they were included because part of the instrument (at least five items) was considered to measure empowerment or manifestations of empowerment. Our study provides an overview of the available questionnaires, which can be used by researchers and practitioners who wish to measure the concept of empowerment among cancer patients. Very few questionnaires were explicitly developed to explore

Background: In England, ‘fast-track’ (also known as ‘two-week wait’) general practitioner referrals for suspected cancer in symptomatic patients are used to shorten diagnostic intervals and are supported by clinical guidelines. However, the use of the fast-track pathway may vary for different patient groups. Methods: We examined data from 669 220 patients with 35 cancers diagnosed in 2006–2010 following either fast-track or ‘routine’ primary-to-secondary care referrals using ‘Routes to Diagnosis’ data. We estimated the proportion of fast-track referrals by sociodemographic characteristic and cancer site and used logistic regression to estimate respective crude and adjusted odds ratios. We additionally explored whether sociodemographic associations varied by cancer. Results: There were large variations in the odds of fast-track referral by cancer (P<0.001). Patients with testicular and breast cancer were most likely to have been diagnosed after a fast-track referral (adjusted odds ratios 2.73 and 2.35, respectively, using rectal cancer as reference); whereas patients with brain cancer and leukaemias least likely (adjusted odds ratios 0.05 and 0.09, respectively, for brain cancer and acute myeloid leukaemia). There were sex, age and deprivation differences in the odds of fast-track referral (P<0.013) that varied in their size and direction for patients with different cancers (P<0.001). For example, fast-track referrals were least likely in younger women with endometrial cancer and in older men with testicular cancer. Conclusions: Fast-track referrals are less likely for cancers characterised by nonspecific presenting symptoms and patients belonging to low cancer incidence demographic groups. Interventions beyond clinical guidelines for ‘alarm’ symptoms are needed to improve diagnostic timeliness. PMID:29182609

A patient-centered perspective on cancer survivorship.

Science.gov (United States)

Zebrack, Brad

2015-04-15

Survivorship is a complicated notion because people often confuse a process of survivorship with a mythic identity of being a cancer survivor. This confusion may be a distraction to addressing the real-life struggles and challenges experienced by all people diagnosed with cancer. A more expansive perspective of survivorship, one that attends to patients' physical, psychological, social, spiritual, and existential challenges throughout a continuum of care, would be more in line with what is known empirically about people's experiences with cancer. In an effort to gain a patient-centered perspective on cancer, and one that emphasizes multiple dimensions of cancer survivorship, the author reports findings from a non-scientific social media poll (via Facebook and personal emails) in which survivors and colleagues working in the field of cancer survivorship answered the question: What does cancer survivorship mean to you? The comments are enlightening and useful for guiding the development of a patient-centered, and, thus, more comprehensive, approach to caring for people affected by cancer.

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.

Caring for cancer patients on non-specialist wards.

LENUS (Irish Health Repository)

Gill, Finola

2012-02-01

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.

According to the recent worldwide estimation by the GLOBOCAN project, in total, 12.7 million new cancer cases and 7.6 million cancer deaths occurred in 2008. The worldwide number of cancer survivors within 5 years of diagnosis has been estimated at be almost 28.8 million. Informal caregivers, such as family members and close friends, provide essential support to cancer patients. The authors of this report provide an overview of issues in the study of informal caregivers for cancer patients and long-term survivors in the United States and Europe, characterizing the caregivers commonly studied; the resources currently available to them; and their unmet needs, their psychosocial outcomes, and the psychosocial interventions tailored to their special circumstances. A broad overview of the state of research and knowledge, both in Europe and the United States, and observations on the directions for future research are provided. PMID:23695928

Haemorheological changes in cancer patients on chemotherapy

To assess the rheological changes in haematological and non-haematological cancer patients pre and post chemotherapy. It is a prospective study of 50 patients comprising 16(32%) haematological and 34(68%) non-haematological cancers of various types from March to December 2005 at University of Benin Teaching Hospital, Nigeria. Rheologic parameters estimated by the various specific diagnostic methods were determined in cancer patient's pre and post chemotherapy. The rheological tests estimated were relative plasma viscosity (RPV) measured by means of a capillary viscometer, whole blood viscosity (WBV), erythrocyte sedimentation rate (ESR) and plasma fibrinogen concentration (PFC) estimated by the Ingram's Clot weight method. The RPV in pre chemotherapy (p=0.006) and WBV in post chemotherapy (p=0.0231) patients measured revealed a significant difference when compared to controls. The fibrinogen concentration (P<0.0001) and ESR values (P<0.0001) were significantly increased in cancer patients when compared to controls. We conclude that total reduction of hyperviscosity and hyperfibrinogenaemia may contribute to effective treatment strategies in cancer patients. (author)

Decreased neural precursor cell pool in NADPH oxidase 2-deficiency: From mouse brain to neural differentiation of patient derived iPSC

Full Text Available There is emerging evidence for the involvement of reactive oxygen species (ROS in the regulation of stem cells and cellular differentiation. Absence of the ROS-generating NADPH oxidase NOX2 in chronic granulomatous disease (CGD patients, predominantly manifests as immune deficiency, but has also been associated with decreased cognition. Here, we investigate the role of NOX enzymes in neuronal homeostasis in adult mouse brain and in neural cells derived from human induced pluripotent stem cells (iPSC. High levels of NOX2 were found in mouse adult neurogenic regions. In NOX2-deficient mice, neurogenic regions showed diminished redox modifications, as well as decrease in neuroprecursor numbers and in expression of genes involved in neural differentiation including NES, BDNF and OTX2. iPSC from healthy subjects and patients with CGD were used to study the role of NOX2 in human in vitro neuronal development. Expression of NOX2 was low in undifferentiated iPSC, upregulated upon neural induction, and disappeared during neuronal differentiation. In human neurospheres, NOX2 protein and ROS generation were polarized within the inner cell layer of rosette structures. NOX2 deficiency in CGD-iPSCs resulted in an abnormal neural induction in vitro, as revealed by a reduced expression of neuroprogenitor markers (NES, BDNF, OTX2, NRSF/REST, and a decreased generation of mature neurons. Vector-mediated NOX2 expression in NOX2-deficient iPSCs rescued neurogenesis. Taken together, our study provides novel evidence for a regulatory role of NOX2 during early stages of neurogenesis in mouse and human.

Recent advances in computer vision enable increasingly accurate automated pattern classification. In the current study we evaluate whether a convolutional neural network (CNN) can be trained to predict disease outcome in patients with colorectal cancer based on images of tumor tissue microarray samples. We compare the prognostic accuracy of CNN features extracted from the whole, unsegmented tissue microarray spot image, with that of CNN features extracted from the epithelial and non-epithelial compartments, respectively. The prognostic accuracy of visually assessed histologic grade is used as a reference. The image data set consists of digitized hematoxylin-eosin (H and E) stained tissue microarray samples obtained from 180 patients with colorectal cancer. The patient samples represent a variety of histological grades, have data available on a series of clinicopathological variables including long-term outcome and ground truth annotations performed by experts. The CNN features extracted from images of the epithelial tissue compartment significantly predicted outcome (hazard ratio (HR) 2.08; CI95% 1.04-4.16; area under the curve (AUC) 0.66) in a test set of 60 patients, as compared to the CNN features extracted from unsegmented images (HR 1.67; CI95% 0.84-3.31, AUC 0.57) and visually assessed histologic grade (HR 1.96; CI95% 0.99-3.88, AUC 0.61). As a conclusion, a deep-learning classifier can be trained to predict outcome of colorectal cancer based on images of H and E stained tissue microarray samples and the CNN features extracted from the epithelial compartment only resulted in a prognostic discrimination comparable to that of visually determined histologic grade.

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.

An increasing number of patients and relatives use the Internet to get additional or initial information about their disease. The aim of the study was to reevaluate the Internet usage among German cancer patients. Using a standardized questionnaire, we did an anonymous survey on patients attending a series of lectures on complementary medicine in 2014. We received 255 questionnaires. Nearly 80 % of the participants stated that they used the Internet to read up information about health or medicine issues. There was no significant difference regarding gender, age, or status (patient, current treatment/former treatment; relatives). Most users use the Internet in order to get additional information after a consultation with a physician (82.2 %). Important qualities from the view of the patient are a trustable source (65.3 %), information from experts (59.6 %), and actual information (52.8 %). There is an increasing number of patients in Germany looking for information in the Internet mostly in the intention of getting additional information. Yet, as the quality of information is heterogeneous, false information may lead to distrust in the doctor or wrong decision-making. Accordingly, organizations working on improving quality of cancer care should engage in conveying comprehensive and actual information adapted to the needs of patients. Physicians should know trustful websites for referral of patients.

Full Text Available Intoduction: Melanosis coli is a benign lesion affecting the mucosa of the large intestine. There is a relationship between the presence of melanosis and anthraquinone laxative use. Melanosis coli is also observed in patients with colon cancer, but there is doubt whether these two conditions are related. Aim : To analyze the correlation between melanosis and colon cancer. Material and methods: We analyzed retrospectively 436 patients undergoing colon cancer surgery. There were 246 women and 190 men. Patients were divided into three age groups: under 50 years, between 51 and 65 years, and over 66 years. We analyzed sections of the cancer and intestinal mucosa from the tumor’s proximal (2–5 cm and distal (8–10 cm zone. Results : Melanosis coli was present in 52 patients, which represents 11.9% of patients with colon cancer. More often it was present in women. The most common location of melanosis and colon cancer was the terminal part of the large intestine. In patients below 50 years of age in both sexes melanosis coli did not occur. In men, melanosis was more common in the age group over 66 years. Intensity of pigmentation was higher in the tumor’s distal zone. Conclusions : The incidence of melanosis coli increases with age, similar to that of colon cancer. Melanosis was not present inside tumors, in almost half of the cases it was not present in the proximal zone, and the degree of pigmentation increased in distal zone. The cause-effect relationship between melanosis coli and colon cancer remains uncertain.

Family history of cancer is a risk factor for gastric cancer. In this study, we investigated the prognoses of gastric cancer patients with family history of cancer. A total of 1805 gastric cancer patients who underwent curative gastrectomy from 2000 to 2008 were evaluated. The clinicopathologic parameters and prognoses of gastric cancer patients with a positive family history (PFH) of cancer were compared with those with a negative family history (NFH). Of 1805 patients, 382 (21.2%) patients had a positive family history of cancer. Positive family history of cancer correlated with younger age, more frequent alcohol and tobacco use, worse differentiation, smaller tumor size, and more frequent tumor location in the lower 1/3 of the stomach. The prognoses of patients with a positive family history of cancer were better than that of patients with a negative family history. Family history of cancer independently correlated with better prognosis after curative gastrectomy in gastric cancer patients.

Abstract Background In some neutropenic cancer patients fever may be absent despite microbiologically and/or clinically confirmed infection. We hypothesized that afebrile neutropenic cancer patients with severe infections have worse outcome as compared to cancer patients with febrile neutropenia. Patients and methods We retrospectively analyzed all adult cancer patients with chemotherapy-induced neutropenia and severe infection, who were admitted to the Intensive Care Unit at our cancer center between 2000 and 2011. The outcome of interest was 30-day in-hospital mortality rate. Association between the febrile status and in-hospital mortality rate was evaluated by the Fisher’s exact test. Results We identified 69 episodes of severe neutropenic infections in 65 cancer patients. Among these, 9 (13%) episodes were afebrile. Patients with afebrile neutropenic infection presented with hypotension, severe fatigue with inappetence, shaking chills, altered mental state or cough and all of them eventually deteriorated to severe sepsis or septic shock. Overall 30-day in-hospital mortality rate was 55.1%. Patients with afebrile neutropenic infection had a trend for a higher 30-day in-hospital mortality rate as compared to patients with febrile neutropenic infection (78% vs. 52%, p = 0.17). Conclusions Afebrile cancer patients with chemotherapy-induced neutropenia and severe infections might have worse outcome as compared to cancer patients with febrile neutropenia. Patients should be informed that severe neutropenic infection without fever can occasionally occur during cancer treatment with chemotherapy. PMID:27904453

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.

To investigate the nutritional status, and provide evidence for nutritional treatment option. A total of 452 patients with gastrointestinal cancer were selected, including 156 gastric cancer,117 colon cancer, and 180 rectal cancer. The nutritional risk screening 2002(NRS2002) was applied to grade the nutritional risk. A multi-frequency bioelectrical impedance analysis was used to measure the patients' body composition. Albumin (Alb), prealbumin(PA), transferring(Tf), retinol binding protein(RBP), red blood cell(RBC), hemoglobin (Hb), haematocrit(Hct) were measured after fasting. The rate of patients with NRS2002 score more than 3 was 70.5%(110/156) for gastric cancer, 53.8%(63/117) for colon cancer, and 46.7%(86/180) for rectal cancer. The score for impaired nutritional status more than 1 for gastric cancer was higher than that for colorectal cancer(Pgastric cancer(Pgastric cancer patients as compared to colorectal cancer patients(Pgastric cancer patients(Pgastric cancer and colon cancer(Pgastric cancer are prone to fat loss and therefore have a higher nutritional risk and malnutrition than those with colorectal cancer. Combination of body composition analysis and laboratory examination may achieve comprehensive evaluation of the nutritional status of patients, and provide the evidence of nutritional therapy by being combined with NRS2002 score.

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

Lung cancer is the cancer type with highest mortality rate worldwide. It has been shown that early detection with computer tomography (CT) scans can reduce deaths caused by this disease. Manual detection of cancer nodules is costly and time-consuming. We present a general framework for the detection of nodules in lung CT images. Our method consists of the pre-processing of a patient's CT with filtering and lung extraction from the entire volume using a previously calculated mask for each patient. From the extracted lungs, we perform a candidate generation stage using morphological operations, followed by the training of a three-dimensional convolutional neural network for feature representation and classification of extracted candidates for false positive reduction. We perform experiments on the publicly available LIDC-IDRI dataset. Our candidate extraction approach is effective to produce precise candidates with a recall of 99.6%. In addition, false positive reduction stage manages to successfully classify candidates and increases precision by a factor of 7.000.

Metallic taste is a taste alteration frequently reported by cancer patients treated with chemotherapy. Attention to this side effect of chemotherapy is limited. This review addresses the definition, assessment methods, prevalence, duration, etiology, and management strategies of metallic taste in chemotherapy treated cancer patients. Literature search for metallic taste and chemotherapy was performed in PubMed up to September 2014, resulting in 184 articles of which 13 articles fulfilled the inclusion criteria: English publications addressing metallic taste in cancer patients treated with FDA-approved chemotherapy. An additional search in Google Scholar, in related articles of both search engines, and subsequent in the reference lists, resulted in 13 additional articles included in this review. Cancer patient forums were visited to explore management strategies. Prevalence of metallic taste ranged from 9.7% to 78% among patients with various cancers, chemotherapy treatments, and treatment phases. No studies have been performed to investigate the influence of metallic taste on dietary intake, body weight, and quality of life. Several management strategies can be recommended for cancer patients: using plastic utensils, eating cold or frozen foods, adding strong herbs, spices, sweetener or acid to foods, eating sweet and sour foods, using 'miracle fruit' supplements, and rinsing with chelating agents. Although metallic taste is a frequent side effect of chemotherapy and a much discussed topic on cancer patient forums, literature regarding metallic taste among chemotherapy treated cancer patients is scarce. More awareness for this side effect can improve the support for these patients. Copyright © 2014 Elsevier Ltd. All rights reserved.

Testicular cancer affects men mostly in their reproductive age with a cure rate over 90% and fertility is one of the main concerns of survivors. To further elucidate the question of fertility after treatment for testicular cancer, we performed a survey in patients treated in our institution. We sent a questionnaire to patients treated for testicular cancer at our institute from 1976 to 2002 (n = 490) of whom 297 (60.6%) responded. We considered the patients to have conserved fertility if they had children after treatment without assisted reproductive technologies. Before treatment 119/297 (40.1%) of patients and after treatment 150/297 (50.5%) of patients tried to have children (p = 0.019). Of 119 patients who tried to have children before treatment for testicular cancer 98 (82.4%) succeeded and 74/150 (49.3%) were successful after treatment (p years. The post-treatment fatherhood in patients treated with surgery only (orchidectomy +/- retroperitoneal lymphnode dissection-RPLND) was 59%, in those with additional radiotherapy 68%, and chemotherapy 50% (p = 0.233). Fertility rate in patients where a non nerve sparing RPLND was performed was only 37%, 62% in patients with nerve sapring RPLND, and 77% in patients where RPLND was not performed (p Fertility rate after treatment for testicular cancer is reduced. From our data, the most important treatment modality that influences fertility is non nerve sparing RPLND that should be avoided whenever possible in order improve the quality of life our patients.

In the last 6 years, we have experienced 20 cancer patients who received home parenteral nutrition for terminal stage. The patients had 13 gastric cancers, 3 esophageal cancers and 5 others. The prognosis of upper G-I cancer is known to be poorer than that of colon cancer. The home care of our cases, the gastric cancer lasted 25 days on average, which was shorter than others. So the home care for patients in the terminal stage of gastric cancer is very short. Therefore we decide the home care for the terminal stage of gastric cancer as soon as possible. We conducted a questionnaire survey of our cases and family. We finally found that the most important thing is the safety of patient for the maintenance of home care. Our home care system is made up of a 3-way relationship among the patient, support system and doctor. The doctor is on call for the problems of the patient for 24 hours. Therefore, we believe that this system is comfortable for both the patient and family.

Patients who receive adjuvant chemotherapy have reported cognitive impairments that may last for years after the completion of treatment. Working memory-related and long-term memory-related changes in this population are not well understood. The objective of this study was to demonstrate that cancer-related cognitive impairments are associated with the under recruitment of brain regions involved in working and recognition memory compared with controls. Oncology patients (n = 15) who were receiving adjuvant chemotherapy and had evidence of cognitive impairment according to neuropsychological testing and self-report and a group of age-matched, education group-matched, cognitively normal control participants (n = 14) underwent functional magnetic resonance imaging. During functional magnetic resonance imaging, participants performed a nonverbal n-back working memory task and a visual recognition task. On the working memory task, when 1-back and 2-back data were averaged and contrasted with 0-back data, significantly reduced activation was observed in the right dorsolateral prefrontal cortex for oncology patients versus controls. On the recognition task, oncology patients displayed decreased activity of the left-middle hippocampus compared with controls. Neuroimaging results were not associated with patient-reported cognition. Decreased recruitment of brain regions associated with the encoding of working memory and recognition memory was observed in the oncology patients compared with the control group. These results suggest that there is a reduction in neural functioning postchemotherapy and corroborate patient-reported cognitive difficulties after cancer treatment, although a direct association was not observed.

Taylor, K

2002-09-01

The author's personal experience as a kidney cancer patient, researcher and founder of a kidney cancer support group forms the basis for consideration of the challenges involved in researching patients' experiences. The researcher needs to understand the variability of those experiences in both clinical and psychological-emotional terms, and in relation to the personal, familial and social contexts of the patient. It is also essential to define the purpose of the research and to show how an understanding of personal experiences of cancer can be used to enhance the quality of care for cancer patients. The research encounter with a patient is also in some respects a therapeutic encounter requiring a considerable degree of sensitivity on the part of the researcher. The person-centred approach of Carl Rogers is of value in supporting such an encounter.

Physiotherapy of cancer patients is one of the most controversial issues in our country. Malignant diseases are firstly mentioned as a contraindication of physiotherapy. Until now, physiotherapy was not suggested (or only in limited accessibility) for those patients who had malignant disease in medical history. International medical practice was less restrictive in managing this topic. The development of imaging techniques put this question in a new light. On the basis of evidence, the majority of articles have reported beneficial effects of physiotherapy in cancer patients, and only few articles mentioned it as harmful. Of course, each patient requires an individual assessment, however, if we exclude the possibility of tumor recurrence and metastasis, most of physiotherapy procedures can be used safely. One of the aims of this review is to support the physicians' decisions when to prescribe treatments, in such a way, that more patients could receive physiotherapy. Orv.

Breast cancer is one of the most common types of cancer in women all over the world. Early diagnosis of this kind of cancer can significantly increase the chances of long-term survival. Since diagnosis of breast cancer is a complex problem, neural network (NN) approaches have been used as a promising solution. Considering the low speed of the back-propagation (BP) algorithm to train a feed-forward NN, we consider a number of improved NN trainings for the Wisconsin breast cancer dataset: BP with momentum, BP with adaptive learning rate, BP with adaptive learning rate and momentum, Polak-Ribikre conjugate gradient algorithm (CGA), Fletcher-Reeves CGA, Powell-Beale CGA, scaled CGA, resilient BP (RBP), one-step secant and quasi-Newton methods. An NN ensemble, which is a learning paradigm to combine a number of NN outputs, is used to improve the accuracy of the classification task. Results demonstrate that NN ensemble-based classification methods have better performance than NN-based algorithms. The highest overall average accuracy is 97.68% obtained by NN ensemble trained by RBP for 50%-50% training-test evaluation method.

Full Text Available Abstract Background Gastrointestinal cancer is the first leading cause of cancer related deaths in men and the second among women in Iran. An investigation was carried out to examine anxiety and depression in this group of patients and to investigate whether the knowledge of cancer diagnosis affect their psychological distress. Methods This was a cross sectional study of anxiety and depression in patients with gastrointestinal cancer attending to the Tehran Cancer Institute. Anxiety and depression was measured using the Hospital Anxiety and Depression Scale (HADS. This is a widely used valid questionnaire to measure psychological distress in cancer patients. Demographic and clinical data also were collected to examine anxiety and depression in sub-group of patients especially in those who knew their cancer diagnosis and those who did not. Results In all 142 patients were studied. The mean age of patients was 54.1 (SD = 14.8, 56% were male, 52% did not know their cancer diagnosis, and their diagnosis was related to esophagus (29%, stomach (30%, small intestine (3%, colon (22% and rectum (16%. The mean anxiety score was 7.6 (SD = 4.5 and for the depression this was 8.4 (SD = 3.8. Overall 47.2% and 57% of patients scored high on both anxiety and depression. There were no significant differences between gender, educational level, marital status, cancer site and anxiety and depression scores whereas those who knew their diagnosis showed a significant higher degree of psychological distress [mean (SD anxiety score: knew diagnosis 9.1 (4.2 vs. 6.3 (4.4 did not know diagnosis, P Conclusion Psychological distress was higher in those who knew their cancer diagnosis. It seems that the cultural issues and the way we provide information for cancer patients play important role in their improved or decreased psychological well-being.

The Institute of Medicine has called for more coordinated cancer care models that correspond to initiatives led by cancer providers and professional organizations. These initiatives parallel those underway to integrate the management of patients with chronic conditions. We developed 5 breast cancer patient and practice management process measures based on the Chronic Care Model. We then performed a survey to evaluate patterns and correlates of these measures among attending surgeons of a population-based sample of patients diagnosed with breast cancer between June 2005 and February 2007 in Los Angeles and Detroit (N = 312; response rate, 75.9%). Surgeon practice specialization varied markedly with about half of the surgeons devoting 15% or less of their total practice to breast cancer, whereas 16.2% of surgeons devoted 50% or more. There was also large variation in the extent of the use of patient and practice management processes with most surgeons reporting low use. Patient and practice management process measures were positively associated with greater levels of surgeon specialization and the presence of a teaching program. Cancer program status was weakly associated with patient and practice management processes. Low uptake of patient and practice management processes among surgeons who treat breast cancer patients may indicate that surgeons are not convinced that these processes matter, or that there are logistical and cost barriers to implementation. More research is needed to understand how large variations in patient and practice management processes might affect the quality of care for patients with breast cancer.

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.

Gastric cancer is one of the most prevalent cancers in the world. Characterized by poor prognosis, it is a frequent cause of cancer in Iran. The aim of the study was to design a predictive model of survival time for patients suffering from gastric cancer. This was a historical cohort conducted between 2011 and 2016. Study population were 277 patients suffering from gastric cancer. Data were gathered from the Iranian Cancer Registry and the laboratory of Emam Reza Hospital in Mashhad, Iran. Patients or their relatives underwent interviews where it was needed. Missing values were imputed by data mining techniques. Fifteen factors were analyzed. Survival was addressed as a dependent variable. Then, the predictive model was designed by combining both genetic algorithm and logistic regression. Matlab 2014 software was used to combine them. Of the 277 patients, only survival of 80 patients was available whose data were used for designing the predictive model. Mean ?SD of missing values for each patient was 4.43?.41 combined predictive model achieved 72.57% accuracy. Sex, birth year, age at diagnosis time, age at diagnosis time of patients' family, family history of gastric cancer, and family history of other gastrointestinal cancers were six parameters associated with patient survival. The study revealed that imputing missing values by data mining techniques have a good accuracy. And it also revealed six parameters extracted by genetic algorithm effect on the survival of patients with gastric cancer. Our combined predictive model, with a good accuracy, is appropriate to forecast the survival of patients suffering from Gastric cancer. So, we suggest policy makers and specialists to apply it for prediction of patients' survival.

Cancers are among the leading causes of morbidity and mortality worldwide, and the number of new cases is expected to rise significantly over the next decades. At the same time, all types of cancer treatment, such as surgery, radiation therapy, and pharmacological therapies are improving in sophistication, precision and in the power to target specific characteristics of individual cancers. Thus, while many cancers may still not be cured they may be converted to chronic diseases. All of these treatments, however, are impeded or precluded by the frequent development of malnutrition and metabolic derangements in cancer patients, induced by the tumor or by its treatment. These evidence-based guidelines were developed to translate current best evidence and expert opinion into recommendations for multi-disciplinary teams responsible for identification, prevention, and treatment of reversible elements of malnutrition in adult cancer patients. The guidelines were commissioned and financially supported by ESPEN and by the European Partnership for Action Against Cancer (EPAAC), an EU level initiative. Members of the guideline group were selected by ESPEN to include a range of professions and fields of expertise. We searched for meta-analyses, systematic reviews and comparative studies based on clinical questions according to the PICO format. The evidence was evaluated and merged to develop clinical recommendations using the GRADE method. Due to the deficits in the available evidence, relevant still open questions were listed and should be addressed by future studies. Malnutrition and a loss of muscle mass are frequent in cancer patients and have a negative effect on clinical outcome. They may be driven by inadequate food intake, decreased physical activity and catabolic metabolic derangements. To screen for, prevent, assess in detail, monitor and treat malnutrition standard operating procedures, responsibilities and a quality control process should be established at each

Full Text Available 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 dysfunctional brain regions 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 three 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. However, the difference in neural control did not result from the differences in cognitive strategies but from diagnosis alone. Based on social reinforcers, schizophrenia patients can learn to regulate localized brain activity. Cognitive strategies and neural network location differ, however, from healthy controls. These data emphasize that for therapeutic interventions in schizophrenia compensatory strategies may emerge. Specific cognitive skills or specific dysfunctional networks should be addressed to train impaired skills. Social neurofeedback based on fMRI may be one method to accomplish precise learning targets.

One of the few instruments to evaluate coping skills among patients with chronic illnesses is the Cuestionario de Afrontamiento al Estrés para Pacientes Oncológicos (CAEPO), created initially for cancer patients. We evaluate how well CAEPO applies to patients with non-cancer chronic illnesses. A total of 344 patients (115 with chronic hepatitis C, 120 with inflammatory bowel disease and 109 with recurrent vertigo) completed the CAEPO. Exploratory factor analysis and Cronbach's alpha provide only partial support for the seven factors suggested by the original CAEPO. A streamlined version with fewer dimensions and items may be a better solution for identifying coping strategies among these patients.

Full Text Available Summary: Background: Demoralization is distinctive psychological distress that involves hopelessness, helplessness, loss of purpose and meaning, and existential distress. Cancer patients' demoralization has been well documented, but little is known regarding older cancer patients and the related factors. Therefore, this study evaluated demoralization syndrome in older cancer patients. Methods: Cancer patients over 61 years old (n = 113, female 59.3%, mean age 65.7 years, range 61–80 diagnosed with heterogeneous types of cancer were recruited. They completed questionnaires in a hospital's inpatient and outpatient units. Their demoralization was measured using the Demoralization Scale-Mandarin Version (DS-MV. The Patient Health Questionnaire-9 (PHQ-9, Distress Thermometer (DT, Beck Scale for Suicide Ideation (BSS, and Posttraumatic Growth Inventory (PTGI were used to measure other psychological statuses and the association with demoralization. Results: The mean DS-MV score was 28.1 (SD = 16.3. In this sample, 57.7% had moderate to high demoralization (18.6% had moderate demoralization, and 38.1% had high demoralization. Twenty-three percent reported a DT score of five and above, 5.5% reported a PHQ-9 score of 10 and above, and 23.9% reported a BSS score greater than zero. Demoralization was associated with suicide ideation, depression, distress, lower education, and the cancer site. Demoralization was not associated with posttraumatic growth, gender, work status, or religion. Conclusion: More than half of older cancer patients have moderate to high demoralization and it is associated with depression, suicide ideation, and distress. Screening and interventions that are better tailored to older cancer patients could improve the quality of care in cancer treatment.

The ultimate goal of cancer treatment is to achieve a complete eradication of the cancer. However, patients with terminal cancer are also treated to obtain an improvement in their quality of life (QOL). In this report, we describe the dramatic response of an end-stage pancreatic cancer patient with cachexia to a combination of hyperthermia (HT) and chemotherapy (CH). The patient was treated with a combination of intermittent 5-fluorouracil (5-FU)/cisplatin (CDDP) therapy and HT. Three months later, the local recurrent cancer had disappeared, the liver metastases were reduced by 80%, the lung metastatic lesion was markedly reduced, tumor markers had returned to normal, and the cachexia had been almost reversed. Performance status (PS) improved from 4 to 1, QOL improved, and the patient survived until his 258th hospital day. In this patient, the combination of CH and HT was useful not only for improvement of cachexia, but also for tumor reduction. A possible mechanism leading to this effect is discussed. (author)

The results and problems of radiotherapy were analyzed in 57 lung cancer patients more than 65 years of age (average age: 74.8 years). Of these, 45 (79%) were irradiated with a total dose exceeding 40 Gy. In these patients, the median survival was 13 months for Stages I and II, 6.5 months for Stage III, and 5 months for Stage IV. The results of combined radiotherapy and chemotherapy were better than those of radiotherapy alone. Also, slightly better results were obtained in patients treated with split-course than continuous-course irradiation. In aged lung cancer patients the prognosis was highly influenced by their respiratory function. Double cancers were present in 9 (16%) of the 57 patients. (author)

Performance on tasks that require saccadic inhibition declines with age and altered inhibitory functioning has also been reported in patients with Alzheimer's disease. Although mild cognitive impairment (MCI) is assumed to be a high-risk factor for conversion to AD, little is known about changes in saccadic inhibition and its neural correlates in this condition. Our study determined whether the neural activation associated with saccadic inhibition is altered in persons with amnestic mild cognitive impairment (aMCI). Functional magnetic resonance imaging (fMRI) revealed decreased activation in parietal lobe in healthy elderly persons compared to young persons and decreased activation in frontal eye fields in aMCI patients compared to healthy elderly persons during the execution of anti-saccades. These results illustrate that the decline in inhibitory functions is associated with impaired frontal activation in aMCI. This alteration in function might reflect early manifestations of AD and provide new insights in the neural activation changes that occur in pathological ageing. PMID:23898312

More than 60% of cancer patients are able to work after cancer diagnosis. However, little is known about their functioning at work. Therefore, the aims of this study were to (1) identify work functioning trajectories in the year following return to work (RTW) in cancer patients and (2) examine baseline sociodemographic, health-related and work-related variables associated with work functioning trajectories. This longitudinal cohort study included 384 cancer patients who have returned to work after cancer diagnosis. Work functioning was measured at baseline, 3, 6, 9 and 12 months follow-up. Latent class growth modeling (LCGM) was used to identify work functioning trajectories. Associations of baseline variables with work functioning trajectories were examined using univariate and multivariate analyses. LCGM analyses with cancer patients who completed on at least three time points the Work Role Functioning Questionnaire (n = 324) identified three work functioning trajectories: "persistently high" (16% of the sample), "moderate to high" (54%) and "persistently low" work functioning (32%). Cancer patients with persistently high work functioning had less time between diagnosis and RTW and had less often a changed meaning of work, while cancer patients with persistently low work functioning reported more baseline cognitive symptoms compared to cancer patients in the other trajectories. This knowledge has implications for cancer care and guidance of cancer patients at work. © 2017 UICC.

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.

Full Text Available Abstract Background Estimated conditional survival for cancer patients diagnosed at different ages and disease stage provides important information for cancer patients and clinicians in planning follow-up, surveillance and ongoing management. Methods Using population-based cancer registry data for New South Wales Australia, we estimated conditional 5-year relative survival for 11 major cancers diagnosed 1972–2006 by time since diagnosis and age and stage at diagnosis. Results 193,182 cases were included, with the most common cancers being prostate (39,851, female breast (36,585 and colorectal (35,455. Five-year relative survival tended to increase with increasing years already survived and improvement was greatest for cancers with poor prognosis at diagnosis (lung or pancreas and for those with advanced stage or older age at diagnosis. After surviving 10 years, conditional 5-year survival was over 95% for 6 localised, 6 regional, 3 distant and 3 unknown stage cancers. For the remaining patient groups, conditional 5-year survival ranged from 74% (for distant stage bladder cancer to 94% (for 4 cancers at different stages, indicating that they continue to have excess mortality 10–15 years after diagnosis. Conclusion These data provide important information for cancer patients, based on age and stage at diagnosis, as they continue on their cancer journey. This information may also be used by clinicians as a tool to make more evidence-based decisions regarding follow-up, surveillance, or ongoing management according to patients' changing survival expectations over time.

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)

Prognosis of Her2-positive breast cancer has changed since the introduction of trastuzumab for treatment in metastatic and early breast cancer. It was described to be even better compared to prognosis of Her2-negative metastatic breast cancer. The purpose of this study was to evaluate the effect of trastuzumab in our cohort. Besides the effect of adjuvant pretreatment with trastuzumab on survival of patients with metastatic Her2-positive breast cancer was analyzed. All patients with primary breast cancer of the Regional Breast Cancer Center Dresden diagnosed during the years 2001-2013 were analyzed for treatment with or without trastuzumab in the adjuvant and in the metastatic treatment setting using Kaplan-Meier survival estimation and Cox regression. Age and tumor stage at time of first diagnosis of breast cancer as well as hormone receptor status, grading, time, and site of metastasis at first diagnosis of distant metastatic disease were analyzed. Of 4.481 female patients with primary breast cancer, 643 presented with metastatic disease. Her2-positive status was documented in 465 patients, including 116 patients with primary or secondary metastases. Median survival of patients with Her2-positive primary metastatic disease was 3.0 years (95% CI 2.3-4.0). After adjustment for other factors, survival was better in patients with Her2-positive breast cancer with trastuzumab therapy compared to Her2-negative metastatic disease (HR 2.10; 95% CI 1.58-2.79). Analysis of influence of adjuvant therapy with and without trastuzumab by Kaplan-Meier showed a trend for better survival in not pretreated patients. Median survival was highest in hormone receptor-positive Her2-positive (triple-positive) primary metastatic breast cancer patients with 3.3 years (95% CI 2.3-4.6). Prognosis of patients with Her2-positive metastatic breast cancer after trastuzumab treatment is more favorable than for Her2-negative breast cancer.

Patient-centered research requires the meaningful involvement of patients and caregivers throughout the research process. The objective of this study was to create a process for sustainable engagement for research prioritization within oncology. From December 2014 to 2016, a network of engaged patients for research prioritization was created in partnership with the Bladder Cancer Advocacy Network (BCAN): the BCAN Patient Survey Network (PSN). The PSN leveraged an online bladder cancer community with additional recruitment through print advertisements and social media campaigns. Prioritized research questions were developed through a modified Delphi process and were iterated through multidisciplinary working groups and a repeat survey. In year 1 of the PSN, 354 patients and caregivers responded to the research prioritization survey; the number of responses increased to 1034 in year 2. The majority of respondents had non-muscle-invasive bladder cancer (NMIBC), and the mean time since diagnosis was 5 years. Stakeholder-identified questions for noninvasive, invasive, and metastatic disease were prioritized by the PSN. Free-text questions were sorted with thematic mapping. Several questions submitted by respondents were among the prioritized research questions. A final prioritized list of research questions was disseminated to various funding agencies, and a highly ranked NMIBC research question was included as a priority area in the 2017 Patient-Centered Outcomes Research Institute announcement of pragmatic trial funding. Patient engagement is needed to identify high-priority research questions in oncology. The BCAN PSN provides a successful example of an engagement infrastructure for annual research prioritization in bladder cancer. The creation of an engagement network sets the groundwork for additional phases of engagement, including design, conduct, and dissemination.

We present the fertility-preserving procedures performed after routine counselling for primary breast cancer patients in a large certified breast cancer centre. Since November 2006, patients aged below 40 years with histologically confirmed breast cancer are routinely counselled on fertility-preserving possibilities before breast surgery and chemotherapy in the fertility centre of the University Women's Hospital in Tuebingen. The recommendations are based on the treatment recommendations of the network FertiPROTEKT. During the last 40 months, 56 primary breast cancer patients were counselled. Forty-one of these patients were hormone receptor positive. Thirty-four patients (63%) underwent fertility-preserving strategies. The majority of the patients (n = 22) decided on ovarian tissue cryopreservation. GnRH protection was performed in 14 patients. In 12 patients an ovarian stimulation protocol was initiated to cryopreserve fertilized or unfertilized oocytes. A combination of different fertility-preserving methods was performed in 12 patients. The preservation of ovarian function and fertility are of great importance to young breast cancer patients. Counselling on fertility-preserving strategies is therefore critical in these patients and should be routinely performed.

Aim The aim of this was to investigate some clinical profiles and lifestyle changes in stoma patients. Background Stoma patients experienced multiple complications due to their ostomy formation. Patients and methods A cross-sectional study performed on 102 random samples of stoma patients. Any patient with adequate physical and mental capability to participate and having had an ostomy in place for at least 3 months was eligible to enter the study. Participants asked to answer study questions concerning age, sex, type of stoma, having permanent or temporary ostomy, underlying cause of stoma formation, type of cancers cause of stoma. Patient also questioned about some lifestyle changes because of stoma including: changing diet, sexual satisfaction (if sexually active after stoma formation), sense of depression, changing job, change clothing style. Results Colostomy was the most common type of stoma followed by ileostomy and urostomy. In 80.4% of patients under study the stoma was permanent. Most patients had a stoma because of cancer (77.5%), with colon cancer (41.2%) being the most common malignant diagnosis. The mean age of cancer patients (56.1±10.9) with stoma was significantly higher than non-cancer patients (44.7±12.9) (p ostomy. Conclusion In conclusion, stoma formation can caused multiple problems for both cancer and non-cancer patients. Counseling of patient is an important component of care that could help stoma patients to adjust with new situations. PMID:24834234

Understanding the informational needs of cancer patients is a requirement to plan any educative care program for them. The aim of this study was to identify Iranian cancer patients' perceptions of informational needs. The study took a qualitative approach. Semi-structured interviews were held with 25 cancer patients in two teaching hospitals in Iran. Transcripts of the interviews underwent conventional content analysis, and categories were extracted. The results came under two main categories: disease-related informational needs and information needs related to daily life. Disease-related informational needs had two subcategories: obtaining information about the nature of disease and obtaining information about disease prognosis. Information needs related to daily life also had two subcategories: obtaining information about healthy lifestyle and obtaining information about regular activities of daily life. The findings provide deep understanding of cancer patients' informational needs in Iran.

To enable better psychosocial, informational, and practical support of Chinese patients with cancer, this study was conducted to identify the specific support needs of Chinese immigrant cancer patients. The Cancer Portal Project at Memorial Sloan-Kettering Cancer Center's Center for Immigrant Health and Cancer Disparities is a patient navigation program that assists underserved and minority cancer patients in obtaining social and economic assistance at ten New York City cancer clinics. This need assessment was conducted as part of the Portal Project. Sixty-four questions were added to the existing Portal Intake Form about the needs and preferences for Chinese-language support and survivorship services. Descriptive analysis was performed, as well as an exploratory principal component's factor analysis to determine if there were any patterns in the services and programs in which patients were interested. Ninety-six patients were approached for participation; 59 agreed to participate. Eighty-eight percent of participants were born in China. Ninety-seven percent preferred to speak Mandarin, Cantonese, or Fujianese in the healthcare setting. When asked about general interest in support programs, 53 % of the participants were "very interested," 27 % were "maybe interested," and 17 % were "not interested." Programs in which more participants were "very interested" included those that would provide information about obtaining financial assistance (79 %) and social assistance (74 %), information on treatment options (67 %), help in coping with the burden of illness on the family (65 %), and information about general healthcare (63 %). The factor analysis resulted in the identification of five factors: social/financial/treatment and care issues, nutrition and exercise/networking/general health care, coping with fear and stress, herbs and dietary supplements, and acupuncture and acupressure. In this study, 80 % of the participants expressed interest in programs tailored for

To present the ways in which race, ethnicity, class, gender, and sexual orientation interact in the context of cancer risk, access to care, and treatment by health care providers. Cancer risk factors, access to care, and treatment for lesbian, gay, bisexual, and transgender (LGBT) patients are discussed within the context of intersectionality and cultural humility. Peer reviewed articles, cancer organizations, and clinical practice. LGBT patients have multiple identities that intersect to create unique experiences. These experiences shape their interactions with the health care system with the potential for positive or negative consequences. More data is needed to describe the outcomes of those experiences and inform clinical practice. Oncology nurses have an obligation to acknowledge patients' multiple identities and use the practice of cultural humility to provide individualized, patient-centered care.

Patients with advanced colorectal cancer have a high incidence of postoperative complications. We sought to identify outcomes of patients who underwent resection for colon cancer by cancer stage. The National Surgical Quality Improvement Program database was used to evaluate all patients who underwent colon resection with a diagnosis of colon cancer from 2012 to 2014. Multivariate logistic regression analysis was performed to investigate patient outcomes by cancer stage. A total of 7,786 colon cancer patients who underwent colon resection were identified. Of these, 10.8% had metastasis at the time of operation. Patients with metastatic disease had significantly increased risks of perioperative morbidity (adjusted odds ratio [AOR]: 1.44, P = .01) and mortality (AOR: 3.72, P = .01). Patients with metastatic disease were significantly younger (AOR: .99, P colon cancer have metastatic disease. Postoperative morbidity and mortality are significantly higher than in patients with localized disease. Published by Elsevier Inc.

The World Health Organization has recently placed new emphasis on the integration of genetic information for gliomas. While tissue sampling remains the criterion standard, noninvasive imaging techniques may provide complimentary insight into clinically relevant genetic mutations. Our aim was to train a convolutional neural network to independently predict underlying molecular genetic mutation status in gliomas with high accuracy and identify the most predictive imaging features for each mutation. MR imaging data and molecular information were retrospectively obtained from The Cancer Imaging Archives for 259 patients with either low- or high-grade gliomas. A convolutional neural network was trained to classify isocitrate dehydrogenase 1 ( IDH1 ) mutation status, 1p/19q codeletion, and O6-methylguanine-DNA methyltransferase ( MGMT ) promotor methylation status. Principal component analysis of the final convolutional neural network layer was used to extract the key imaging features critical for successful classification. Classification had high accuracy: IDH1 mutation status, 94%; 1p/19q codeletion, 92%; and MGMT promotor methylation status, 83%. Each genetic category was also associated with distinctive imaging features such as definition of tumor margins, T1 and FLAIR suppression, extent of edema, extent of necrosis, and textural features. Our results indicate that for The Cancer Imaging Archives dataset, machine-learning approaches allow classification of individual genetic mutations of both low- and high-grade gliomas. We show that relevant MR imaging features acquired from an added dimensionality-reduction technique demonstrate that neural networks are capable of learning key imaging components without prior feature selection or human-directed training. © 2018 by American Journal of Neuroradiology.

Breast cancer patients receiving chemotherapy often experience symptoms such as nausea, vomiting and loss of appetite that potentially affect dietary habits. This study assessed the intake of energy, macronutrients and food groups before and during chemotherapy in breast cancer patients compared with women without cancer, and determined the association between symptoms and energy and macronutrient intake. This study included 117 newly diagnosed breast cancer patients scheduled for chemotherapy and 88 women without cancer. Habitual intake before chemotherapy was assessed with a food frequency questionnaire. Two 24-h dietary recalls were completed on random days for each participant during the whole chemotherapy treatment for patients and within 6 months after recruitment for women without cancer. Shortly, after the dietary recall, participants filled out questionnaires on symptoms. Before chemotherapy, habitual energy and macronutrient intake was similar for breast cancer patients and women without cancer. During chemotherapy, breast cancer patients reported a significantly lower total energy, fat, protein and alcohol intake than women without cancer, as shown by a lower intake of pastry and biscuits, cheese, legumes and meat products. A decline in subjective taste perception, appetite and hunger and experiencing a dry mouth, difficulty chewing, lack of energy and nausea were associated with a lower energy intake. Symptoms induced by chemotherapy are associated with lower dietary intake and manifested by a lower intake of specific food groups. To ensure an optimal dietary intake during chemotherapy, it is important to monitor nutritional status and symptom burden during chemotherapy in breast cancer patients.

Background A comprehensive assessment of cannabis use by patients with cancer has not previously been reported. In this study, we aimed to characterize patient perspectives about cannabis and its use. Methods An anonymous survey about cannabis use was offered to patients 18 years of age and older attending 2 comprehensive and 2 community cancer centres, comprising an entire provincial health care jurisdiction in Canada (ethics id: hreba-17011). Results Of 3138 surveys distributed, 2040 surveys were returned (65%), with 1987 being sufficiently complete for analysis (response rate: 63%). Of the respondents, 812 (41%) were less than 60 years of age; 45% identified as male, and 55% as female; and 44% had completed college or higher education. Of respondents overall, 43% reported any lifetime cannabis use. That finding was independent of age, sex, education level, and cancer histology. Cannabis was acquired through friends (80%), regulated medical dispensaries (10%), and other means (6%). Of patients with any use, 81% had used dried leaves. Of the 356 patients who reported cannabis use within the 6 months preceding the survey (18% of respondents with sufficiently complete surveys), 36% were new users. Their reasons for use included cancer-related pain (46%), nausea (34%), other cancer symptoms (31%), and non-cancer-related reasons (56%). Conclusions The survey demonstrated that prior cannabis use was widespread among patients with cancer (43%). One in eight respondents identified at least 1 cancer-related symptom for which they were using cannabis.

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

The purpose of this study was to explore the relationships among cancer impact, belief in complementary and alternative medicine (CAM), CAM use, and quality of life (QOL). The study used a cross-sectional, descriptive correlational design with convenience sampling. A total of 122 cancer patients participated. Data were collected at a medical center in Chunghua, Taiwan. The questionnaires included the Chinese version of the Cancer Problem in Living Scale (CPILS), Complementary and Alternative Medicine Belief Inventory (CAMBI), Complementary and Alternative Medicine scale, and Chinese versions of QOL scales, including the Functional Assessment of Cancer Therapy-General (FACT-G). The mean age was 56.5 years, and most participants were male (n = 69, 56.6%), had completed high school or above (n = 56, 45.9%), and were married (n = 109, 89.3%). The most common type of cancer was oral (n = 17, 13.9%), followed by esophageal (n = 15, 12.3%) and colorectal (n = 13, 10.7%). Cancer patients, on average, use one or two types of CAM. The impact of cancer is significantly related to age (F = 7.12, p cancer was highly negatively associated with QOL (r = -0.71, p = 0.001). The predictors of QOL were the impact of cancer and use of CAM, and the impact of cancer accounted for 51% of the variance in QOL. This study supports research on the impact of cancer, belief in CAM, and use of CAM as related to QOL in cancer patients. These results can be used to provide options to clinicians and cancer patients.

Recently published articles have established that a substantial number of cancer patients utilize the Internet to gather information about their respective diagnoses. The challenges for medical providers include understanding the prevalence and characteristics of patients using the Internet, reasons for Internet use, and the effectiveness of currently available websites in providing useful health-related information to patients. Adults with cancer were asked to complete a self-administered, anonymous, 21-item questionnaire upon registration at the Alvin J. Siteman Cancer Center at the Washington University School of Medicine. There were 500 respondents (mean age 58 years (range 18-90), 83% Caucasian and 15% African-American). Three hundred ninety-eight participants (80%) reported access to the Internet, and 315 (63%) reported searching for information about cancer on the Internet. Patients accessing the Internet for cancer information were younger than those who did not (median age 56 vs. 63 years; p Internet usage for cancer information also differed by race (p Internet for cancer information, 13.3% of patients had their decisions towards treatments affected or changed, and 11.4% of patients had their choice in physicians affected or changed because of Internet use; 23.5% of patients sought information on clinical trials, and 9.5% of patients were influenced or changed their decision regarding clinical trial enrollment due to Internet information. Approximately two thirds of patients with cancer used the Internet to obtain information about their disease. Factors affecting Internet use for cancer information included age, race, and education. Clinical decisions can be affected by Internet use.

Nahleh, Zeina; Tabbara, Imad A

2003-09-01

Complementary and Alternative Medicine (CAM) is becoming increasingly popular among cancer patients, in particular those with breast cancer. It represents one of the fastest growing treatment modalities in the United States. Therefore, knowledge of CAM therapies is becoming necessary for physicians and other health care providers. CAM encompasses a wide range of modalities including special diet and nutrition, mind-body approaches, and traditional Chinese medicine. We reviewed the biomedical literature on CAM use in breast cancer patients, using Medline search from 1975 until 2002. In addition, consensus reports and books on CAM and breast cancer were included in the review. We evaluated the prevalence of CAM use in breast cancer patients, the reasons cited for its use, the different available modalities, and the reported outcomes. Use of CAM in breast cancer patients ranges between 48% and 70% in the United States. The most commonly used CAM modalities include dietary supplements, mind-body approaches, and acupuncture. The reasons cited for using CAM were to boost the immune system, improve the quality of life, prevent recurrence of cancer, provide control over life, and treat breast cancer and the side effects of treatment. Several studies reported favorable results including improved survival, better pain control, reduced anxiety, improvement in coping strategies and significant efficacy in treating nausea and vomiting. Other less well-organized trials have reported either no benefit or negative effect of CAM and potential toxicity of some commercial products. CAM is a growing field in health care and particularly among breast cancer patients. Knowledge of CAM by physicians, especially oncologists, is necessary. Oncologists should be willing to discuss the role of CAM with their patients and encourage patients to participate in well-organized research about CAM.

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.

The purpose of the present study was to describe the survival of patients diagnosed with oral cavity cancer in Germany. The analyses relied on data from eleven population-based cancer registries in Germany covering a population of 33 million inhabitants. Patients with a diagnosis of oral cavity cancer (ICD-10: C00-06) between 1997 and 2006 are included. Period analysis for 2002–2006 was applied to estimate five-year age-standardized relative survival, taking into account patients' sex as well as grade and tumor stage. Overall five-year relative survival for oral cavity cancer patients was 54.6%. According to tumor localization, five-year survival was 86.5% for lip cancer, 48.1% for tongue cancer and 51.7% for other regions of the oral cavity. Differences in survival were identified with respect to age, sex, tumor grade and stage. The present study is the first to provide a comprehensive overview on survival of oral cavity cancer patients in Germany. PMID:23349710

According to the definition by the International Agency for Research on Cancer (IARC), primary multiple neoplasms are two or more neoplasms of different histopathological build in one organ, or two or more tumors occurring in one patient, regardless of the time of their occurrence (synchronic - up to 6 months, metachronous - after 6 months), coming from an organ or a tissue and not being an infiltration from another neoplasm, a relapse or a metastasis. It was the aim of the study to analyze the frequency of the occurrence of multiple neoplasms among patients suffering from uterine cervix cancer, with a special interest in coexistent neoplasms, the time of their occurrence and total 5-year survivals. The data from the Lower Silesian Cancer Registry concerning the years 1984-2009 formed the material of the present study. 5.3% of all cervix neoplasms occurred as multiple cancers. Cervix neoplasms were 13.4% of multiple neoplasms. On average, cervical cancer occurred as a subsequent cancer in 6 patients yearly (60.7% of the occurrences of cervical cancer were in the period of 5 years following treatment for the first neoplasm). 5-year survival in patients suffering from primarily multiple cervix neoplasms constituted 57% and was convergent with the results for all patients suffering from cervical cancer. Cervical cancer as the first neoplasm occurred in 287 patients, on average in 11 patients annually. In the period of the first 5 years after the treatment of cervical cancer, there were 42.8% occurrences of other cancers. Cervical neoplasms most frequently coexisted with cancers of the breast, lung and large intestine. The frequency of the occurrence of multiple neoplasm among cervical cancer patients is increasing. Most frequently they coexist with other tobacco-related neoplasms, those related to HPV infections and with secondary post-radiation neoplasms. These facts should be taken into consideration during post-treatment observation and when directing diagnostic

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.

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.Retrospective cohort study.The hematologic malignancy unit in an academic medical center in the United States.Adult patients admitted to the hematologic malignancy unit from 2009 to 2010.None.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.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.

Gastrointestinal cancer is the first leading cause of cancer related deaths in men and the second among women in Iran. An investigation was carried out to examine anxiety and depression in this group of patients and to investigate whether the knowledge of cancer diagnosis affect their psychological distress. This was a cross sectional study of anxiety and depression in patients with gastrointestinal cancer attending to the Tehran Cancer Institute. Anxiety and depression was measured using the Hospital Anxiety and Depression Scale (HADS). This is a widely used valid questionnaire to measure psychological distress in cancer patients. Demographic and clinical data also were collected to examine anxiety and depression in sub-group of patients especially in those who knew their cancer diagnosis and those who did not. In all 142 patients were studied. The mean age of patients was 54.1 (SD = 14.8), 56% were male, 52% did not know their cancer diagnosis, and their diagnosis was related to esophagus (29%), stomach (30%), small intestine (3%), colon (22%) and rectum (16%). The mean anxiety score was 7.6 (SD = 4.5) and for the depression this was 8.4 (SD = 3.8). Overall 47.2% and 57% of patients scored high on both anxiety and depression. There were no significant differences between gender, educational level, marital status, cancer site and anxiety and depression scores whereas those who knew their diagnosis showed a significant higher degree of psychological distress [mean (SD) anxiety score: knew diagnosis 9.1 (4.2) vs. 6.3 (4.4) did not know diagnosis, P < 0.001; mean (SD) depression score: knew diagnosis 9.1 (4.1) vs. 7.9 (3.6) did not know diagnosis, P = 0.05]. Performing logistic regression analysis while controlling for demographic and clinical variables studied the results indicated that those who knew their cancer diagnosis showed a significant higher risk of anxiety [OR: 2.7, 95% CI: 1.1-6.8] and depression [OR: 2.8, 95% CI: 1.1-7.2]. Psychological distress was

Advance directives are a sensitive issue among traditional Chinese people, who usually refrain from mentioning this topic until it is imperative. Medical decisions for cancer patients are made by their families, and these decisions might violate patients' personal will. This study aimed to examine the acceptance of advance directives among Chinese cancer patients and their families and patient participation in this procedure and, finally, to analyze the moral risk involved. While 246 patients and their family members refused official discussion of an advance directive, the remaining 166 patients and their families accepted the concept of an advance directive and signed a document agreeing to give up invasive treatment when the anti-cancer treatment was terminated. Of these, only 24 patients participated in the decision making. For 101 patients, anti-cancer therapy was ended prematurely with as many as 37 patients not told about their potential loss of health interests. Participants were 412 adult cancer patients from 9 leading hospitals across China. An advance directive was introduced to the main decision makers for each patient; if they wished to sign it, the advance directive would be systematically discussed. A questionnaire was given to the oncologists in charge of each patient to evaluate the interaction between families and patients, patients' awareness of their disease, and participation in an advance directive. Advance directives were not widely accepted among Chinese cancer patients unless anti-cancer therapy was terminated. Most cancer patients were excluded from the discussion of an advance directive.

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

This study aims to investigate the effects of illustrations in online cancer information on older cancer patients' website satisfaction (i.e. satisfaction with the attractiveness, comprehensibility and emotional support from the website) and recall of information. In an online experiment, 174 younger (text-only information, text with two cognitive illustrations or text with two affective illustrations. In general, adding cognitive illustrations compared with text-only information improved the satisfaction with the attractiveness of the website in both younger and older patients. For older patients in particular, cognitive illustrations facilitated recall of cancer information: whereas older patients recalled less information overall compared with younger patients (39% vs. 50%), no statistically significant differences in age on recall were observed when cognitive illustrations were added to text. Furthermore, older patients were more satisfied with the emotional support from the website than younger patients, especially when affective illustrations were present. Our results suggest that effective online cancer communication for ageing populations involves considering both cognitive and affective illustrations to enhance website satisfaction and recall of cancer information. © 2015 John Wiley & Sons Ltd.

Extreme emotional reactivity is a defining feature of borderline personality disorder, yet the neural-behavioral mechanisms underlying this affective instability are poorly understood. One possible contributor is diminished ability to engage the mechanism of emotional habituation. The authors tested this hypothesis by examining behavioral and neural correlates of habituation in borderline patients, healthy comparison subjects, and a psychopathological comparison group of patients with avoidant personality disorder. During fMRI scanning, borderline patients, healthy subjects, and avoidant personality disorder patients viewed novel and repeated pictures, providing valence ratings at each presentation. Statistical parametric maps of the contrasts of activation during repeated versus novel negative picture viewing were compared between groups. Psychophysiological interaction analysis was employed to examine functional connectivity differences between groups. Unlike healthy subjects, neither borderline nor avoidant personality disorder patients exhibited increased activity in the dorsal anterior cingulate cortex when viewing repeated versus novel pictures. This lack of an increase in dorsal anterior cingulate activity was associated with greater affective instability in borderline patients. In addition, borderline and avoidant patients exhibited smaller increases in insula-amygdala functional connectivity than healthy subjects and, unlike healthy subjects, did not show habituation in ratings of the emotional intensity of the images. Borderline patients differed from avoidant patients in insula-ventral anterior cingulate functional connectivity during habituation. Unlike healthy subjects, borderline patients fail to habituate to negative pictures, and they differ from both healthy subjects and avoidant patients in neural activity during habituation. A failure to effectively engage emotional habituation processes may contribute to affective instability in borderline

[Nutrition therapy of cancer patients].

Lövey, József

The majority of cancer patients becomes malnourished during the course of their disease. Malnutrition deteriorates the efficiency of all kinds of oncologic interventions. As a consequence of it, treatment-related toxicity increases, hospital stay is lengthened, chances of cure and survival as well as the quality of life of the patients worsen. Nutritional status therefore influences all aspects of outcome of oncology care. In spite of this the use of nutritional therapy varies across health care providers but its application is far from being sufficient during active oncology interventions as well as rehabilitation and supportive care. It threatens not only the outcome and quality of life of cancer patients but also the success of oncologic treatments which often demand high input of human and financial resources. Meanwhile application of nutritional therapy is legally regulated in Hungary and a very recent update of the European guideline on cancer patient nutrition published in 2017 is available. Moreover, cost effectiveness of nutritional therapy has been proven in a number of studies. In this review we present the basics of nutritional therapy including nutritional screening and evaluation, nutritional plan, the role of nutrition support teams, oral, enteral and parenteral nutrition, the use of different drugs and special nutrients and the follow-up of the patients.

Art therapy is a healing art intended to integrate physical, emotional, and spiritual care by facilitating creative ways for patients to respond to their cancer experience. A new art therapy program was designed to provide cancer patients with opportunities to learn about the McMichael Canadian Art Collection and to explore personal feelings about their cancer experience through combined gallery and studio components. The role of the facilitator was to assist in the interpretation of a participant's drawing in order to reveal meaning in the art. This paper presents patients' perspectives about the new art therapy program. Content analysis of participant feedback provided information about the structure, process, and outcomes of the program. Evaluation of the art therapy/museum education program demonstrated many benefits for cancer patients including support, psychological strength, and new insights about their cancer experience.

Twitter has been recognized as an important source of organic sentiment and opinion. This study aimed to (1) characterize the content of tweets authored by the United States cancer patients; and (2) use patient tweets to compute the average happiness of cancer patients for each cancer diagnosis. A large sample of English tweets from March 2014 through December 2014 was obtained from Twitter. Using regular expression software pattern matching, the tweets were filtered by cancer diagnosis. For each cancer-specific tweetset, individual patients were extracted, and the content of the tweet was categorized. The patients' Twitter identification numbers were used to gather all tweets for each patient, and happiness values for patient tweets were calculated using a quantitative hedonometric analysis. The most frequently tweeted cancers were breast (n = 15,421, 11% of total cancer tweets), lung (n = 2928, 2.0%), prostate (n = 1036, 0.7%), and colorectal (n = 773, 0.5%). Patient tweets pertained to the treatment course (n = 73, 26%), diagnosis (n = 65, 23%), and then surgery and/or biopsy (n = 42, 15%). Computed happiness values for each cancer diagnosis revealed higher average happiness values for thyroid (h_avg = 6.1625), breast (h_avg = 6.1485), and lymphoma (h_avg = 6.0977) cancers and lower average happiness values for pancreatic (h_avg = 5.8766), lung (h_avg = 5.8733), and kidney (h_avg = 5.8464) cancers. The study confirms that patients are expressing themselves openly on social media about their illness and that unique cancer diagnoses are correlated with varying degrees of happiness. Twitter can be employed as a tool to identify patient needs and as a means to gauge the cancer patient experience. Copyright © 2016 Elsevier Inc. All rights reserved.

Fertility preservation in young cancer patients

Ariel Revel

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.

To determine whether the sonographic appearance of thyroid cancer differs in patients with and without Hashimoto thyroiditis. Patients with histologically proven thyroid cancer who had thyroid peroxidase (TPO) antibodies measured and sonography performed preoperatively were included. We evaluated each nodule for size, echogenicity, composition, margins, halo, and vascularity and evaluated the background heterogeneity of the gland. There were 162 thyroid cancers in 145 patients. Forty-two patients (29.0%) had Hashimoto thyroiditis with positive TPO antibodies, and 103 patients (71.0%) had negative TPO antibodies. The background echogenicity was more often heterogeneous in TPO antibody-positive patients compared to those who had negative TPO antibodies (57.1% versus 26.2%; P= .0005). Comparing cancers in TPO antibody-positive to TPO antibody-negative patients, there was no significant difference in the size, echogenicity, composition, margins, halo presence, calcification presence and type, or vascularity of the cancerous nodule (P > .05). Among TPO antibody-positive patients, comparing thyroid cancerous nodules in patients with heterogeneous glands to those with homogeneous glands, there was no significant difference in any sonographic characteristic except the margin of the nodule, which was more often irregular or poorly defined in heterogeneous glands and more often smooth in homogeneous glands (Pthyroid cancer are similar in patients with and without Hashimoto thyroiditis. Among patients with Hashimoto thyroiditis and thyroid cancer, the sonographic appearance of the cancerous nodule is similar, except that cancerous nodule margins are more likely to be irregular or poorly defined when the gland is heterogeneous. © 2015 by the American Institute of Ultrasound in Medicine.

Over half of cancer patients receive radiotherapy (RT) as partial or full cancer treatment. Daily quality assurance (QA) of RT in cancer treatment closely monitors the performance of the medical linear accelerator (Linac) and is critical for continuous improvement of patient safety and quality of care. Cumulative longitudinal QA measurements are valuable for understanding the behavior of the Linac and allow physicists to identify trends in the output and take preventive actions. In this study, artificial neural networks (ANNs) and autoregressive moving average (ARMA) time-series prediction modeling techniques were both applied to 5-year daily Linac QA data. Verification tests and other evaluations were then performed for all models. Preliminary results showed that ANN time-series predictive modeling has more advantages over ARMA techniques for accurate and effective applicability in the dosimetry and QA field. © 2016 New York Academy of Sciences.

To assess the value of hepatic ultrasound in cancer patients, a prospective evaluation was performed by comparing the preoperative ultrasound report and surgeon's diagnosis at the time of operation in 86 patients with stomach cancer and 26 patients with colon cancer. In a total of 112 patients considered to have a metastasis free liver on ultrasound scanning 10 patients were turned out to have had hepatic metastasis at the time of laparotomy. Among these, 4 patients had miliary metastasis, 4 patients had nodular metastasis at the dome of the right hepatic lobe, and 2 patients had surface metastasis or direct invasion from the primary tumor. These observations suggest that false negative preoperative hepatic ultrasound scanning is 9% had this is considered due to small size of the metastatic lesions, and lesions roundabout the dome of the right hepatic lobe or surface metastasis. Thus one should keep in mind the possibility of miliary metastasis in cancer patient was has coarse hepatic echotexture. In addition, the hepatic dome as well as hepatic surfaces should be searched carefully as the lesions in these areas tend to be easily neglected by ultrasound

Small cell lung cancer (SCLC) is characterized by a relatively high rate of autoimmune phenomena. Paraneoplastic limbic encephalitis (PLE) is an autoimmune syndrome in which a non-neural tumor containing an antigen normally present in the nervous system precipitates an antibody attack on neural tissues. Patients with PLE usually present with rapidly progressive short-term memory deficits, confusion or even dementia. Palmar fasciitis and polyarthritis syndrome (PFPAS) is another autoimmune syndrome characterized by rheumatologic manifestations, especially involving the palms of the hands. We report a case of a 59-year old woman who presented with worsening neurological symptoms of two-week duration, and later coma. The combined clinical, serological, and imaging studies suggested a diagnosis of PLE. A chest computed tomographic scan showed a 1.2 cm-diameter mass in the upper lobe of the left lung that was surgically removed and showed SCLC. Following surgery, neurological symptoms rapidly improved, allowing the patient to receive adjuvant chemotherapy. While in remission for both SCLC and PLE, the patient developed pain, soft-tissue swelling, and stiffness in both palms, suggesting the diagnosis of PFPAS. Five months following the diagnosis of palmar fasciitis, SCLC relapsed with mediastinal and cervical lymphadenopathy. This case report underlines the continuous interaction of SCLC with the immune system, expressed by coexistence of two rare paraneoplastic diseases, PLE, and PFPAS, in a patient with SCLC. While symptoms related to PLE preceded the initial diagnosis of SCLC, other symptoms related to PFPAS preceded relapse.

Full Text Available Background: The current study investigated the possible role of the cell cycle regulator, cyclin-dependent kinases regulatory subunit-2; the angiogenic factor, plateletderived endothelial cell growth factor; and the cell adhesive molecule, neural cadherin, as prognostic factors in schistosomal and non-schistosomal-associated urothelial carcinomas. We also investigated the possible correlation between cyclin-dependent kinases regulatory subunit-2, platelet-derived endothelial cell growth factor, neural cadherin, tumor grade, and stage. Methods: The study included 40 patients with primary bladder cancer (25 nonschistosomal- associated and 15 schistosomal-associated who had no prior anticancer treatment. Tumor specimens were collected at the time of the transurethral resection. The vivid portions of the resected tumors were subjected to routine pathological examinations to determine stage, grade, and schistosomal infestation. Control bladder tissues (5 cases were obtained by cystoscopic biopsies from patients who underwent transurethral resection of the prostate. Platelet-derived endothelial cell growth factor and neural cadherin protein expressions were evaluated by immunohistochemical staining. RNA was extracted, reverse transcribed, and amplified by PCR using cyclindependent kinases regulatory subunit-2 specific primers. Relative expression was detected by a comparison of the expression in normal and tumor samples relative to GAPDH (housekeeping gene expression. Results:We detected a positive correlation between neural cadherin and plateletderived endothelial cell growth factor proteins in schistosomal-associated and non-schistosomal-associated bladder cancer. Significant overexpression of relative cyclin-dependent kinases regulatory subunit-2 gene, neural cadherin, and plateletderived endothelial cell growth factor proteins were detected in invasive stages and higher grades of bladder cancer.

Chronic fatigue in cancer patients treated with radiotherapy

Rucinska, M.; Wojtukiewicz, M.Z.; Tokajuk, P.

2004-01-01

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)

Active listening to cancer patients' stories.

Approximately two thirds of all Dutch cancer patients have severe emotional problems; shortly after their change from the treatment regime into the regime of medical controls. Half of them even need professional support. It is, therefore, important that a professional listens with empathy to the patient's version of the illness story. Story telling helps to overcome the existential crisis of being a cancer patient; it is an essential step in the revalidation process. Themes and open questions which structure the communication are suggested in this article.

Neural Changes following Behavioral Activation for a Depressed Breast Cancer Patient: A Functional MRI Case Study

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.

The place of death of patients with cancer in Kuwait.

2015-12-01

The place of death (PoD) has a significant effect on end-of-life care for patients dying of cancer. Little is known about the place of cancer deaths in our region. To identify the PoD of patients with cancer in Kuwait, we reviewed the death certificates submitted to the Kuwait Cancer Registry in 2009. Of 611 cancer deaths, 603 (98.7%) died in hospitals and only 6 (1%) patients died at home. More than half (57.3%) of inhospital deaths were in the Kuwait Cancer Control Center. Among those for whom the exact PoD within the hospital was identified (484 patients), 116 (24%) patients died in intensive care units and 12 (2.5%) patients died in emergency rooms. This almost exclusive inhospital death of patients with cancer in Kuwait is the highest ever reported. Research is needed to identify the reasons behind this pattern of PoD and to explore interventions promoting out-of-hospital death among terminally ill cancer patients in Kuwait.

2016-03-01

The implications for patients with cancer, of the 'tablet burden' resulting from increasing use of oral anticancer drugs and medication for co-morbidities have not previously been well explored. We sought to (i) quantify tablet burden in women with metastatic breast cancer (MBC), (ii) establish which groups of drug contribute most to this burden and (iii) gain insight into patients' attitudes towards oral anti-cancer treatment. One hundred patients with MBC anonymously completed a questionnaire describing their medication histories and attitudes towards their tablets. The patients (mean age 60, range 31-95) were all female and taking a median of six tablets (range 0-31) daily; 37 patients were taking >10 tablets. Oral anticancer treatment constituted the category of treatment taken by the highest proportion of patients, followed by symptomatic cancer treatments, proton pump inhibitors and cardiovascular medication. Numerically, however, symptomatic drugs accounted for 44% of all tablets and specific anti-cancer treatment for 15%; medication not directly related to the cancer accounted for the remaining 40% of tablets. A quarter of patients reported inconvenience in taking their tablets, the main reason being tablet size and one third reported forgetting their tablets at least once a week. Nearly two thirds of patients expressing a preference favoured oral anticancer treatment, the commonest reason being greater convenience. Tablet burden is considerable for many patients with MBC and can be problematic. A significant proportion of tablets represent treatment for co-morbidities, the significance of which may be questionable in women with MBC. Copyright © 2015 Elsevier Ltd. All rights reserved.

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

Despite the mounting evidence of efficacy of eHealth interventions, their mechanisms of action remain unknown. The current study analyzed patient log data as each patient engaged in an eHealth system called the Comprehensive Health Enhancement Support System (CHESS) and reports on how patients engage with different combinations of eHealth services over time. Newly diagnosed breast cancer patients (N = 443) were given access for 6 months to one of four different configurations of CHESS: (1) Information, (2) Information and Support, (3) Information, Support, and Coaching (Full CHESS), and (4) Full CHESS and Mentor. Besides a baseline survey, three follow-up posttests were administered. Action log data on how patients engaged with the CHESS were also collected and merged with surveys to examine how patients benefit during the cancer experience. The findings suggest that usage patterns were not competitive, implying that cancer patients' access to more complex tools generates more use with their time spreading out over the diverse services. Despite overall decline in usage rates, it was less severe in Full CHESS and Mentor condition, suggesting that communication functions drive long-term engagement with the system. Notably, the strongest relation between use and cancer information competence appeared late in the follow-up period.

Palliative care is often focused on cancer patients. Palliative sedation at the end of life is an intervention to address severe suffering in the last stage of life. To study the practice of continuous palliative sedation for both cancer and noncancer patients. In 2008, a structured questionnaire was sent to 1580 physicians regarding their last patient receiving continuous sedation until death. A total of 606 physicians (38%) filled out the questionnaire, of whom 370 (61%) reported on their last case of continuous sedation (cancer patients: n=282 [76%] and noncancer patients: n=88 [24%]). More often, noncancer patients were older, female, and not fully competent. Dyspnea (odds ratio [OR]=2.13; 95% confidence interval [CI]: 1.22, 3.72) and psychological exhaustion (OR=2.64; 95% CI: 1.26, 5.55) were more often a decisive indication for continuous sedation for these patients. A palliative care team was consulted less often for noncancer patients (OR=0.45; 95% CI: 0.21, 0.96). Also, preceding sedation, euthanasia was discussed less often with noncancer patients (OR=0.42; 95% CI: 0.24, 0.73), whereas their relatives more often initiated discussion about euthanasia than relatives of cancer patients (OR=3.75; 95% CI: 1.26, 11.20). The practice of continuous palliative sedation in patients dying of cancer differs from patients dying of other diseases. These differences seem to be related to the less predictable course of noncancer diseases, which may reduce physicians' awareness of the imminence of death. Increased attention to noncancer diseases in palliative care practice and research is, therefore, crucial as is more attention to the potential benefits of palliative care consultation.

Full text: The coexistence of hyperthyroidism and thyroid cancer is a rare event. The aim of this study was to evaluate the relevance of the association of hyperthyroidism and thyroid cancer. Method: From 1st January 2006 to 31st December 2006, a total of 388 new hyperthyroid patients attended the Institute of Nuclear Medicine and Ultrasound for radioiodine therapy. Eighty-two of them were selected before radioiodine therapy, on the basis of findings on palpation and ultrasound (USG) examination, to undergo fine needle aspiration cytology (FNAC) for cytological diagnosis. USG examination was performed to localize and mark the position of nodule/nodules for FNAC and, in cases of nonpalpable nodules, USG guided FNAC was done. In the case of non-nodular patients, guided FNAC was done in sonographically suspicious areas. Results: FNAC report was positive for thyroid cancer in 4 patients. Histopathology examination revealed the presence of papillary carcinoma. Among the four positive cases, one had multi-nodular goitre, two had uni-nodular goiters and one had no nodule. Another patient had a negative FNAC report but due to a huge goiter, the patient underwent surgery and histopathology revealed the presence of papillary carcinoma. Conclusion: Although the occurrence of thyroid cancer in hyperthyroid patients is rare, the presence of a nodule should be carefully evaluated to exclude the presence of concurrent malignancy. FNAC (USG guided in case of non-palpable nodules) is found helpful before radioiodine therapy or surgery. (author)

To compare the prevalence of malnutrition and nutritional management between elderly (≥70years old) and younger patients (malnutrition in adult patients with cancer in France. Patients diagnosed with cancer at the study date in both inpatient and outpatient settings were included. Data collection was performed by means of questionnaires completed by the physician, the patient and the caregiver. This post-hoc analysis compared 578 elderly patients (27.6%) vs. 1517 younger patients (72.4%). There were significant differences in cancer localization between the groups particularly in gastrointestinal cancer (27% in younger patients vs. 42% in elderly), breast cancer (17% vs 8% in elderly) and oropharyngeal (15% vs. 9% in elderly). Weight loss was significantly more reported in the elderly than in younger patients (73.6% vs. 67.6%, p=0.009). Elderly patients were more frequently malnourished than younger patients (44.9% vs. 36.7%, p=0.0006). Food intake was comparable between the groups; however, physicians overestimated the food intake, particularly in the elderly. The malnutrition management was more frequently proposed in elderly, as dietary advice and oral nutritional supplements, than in younger patients; however, enteral nutrition was significantly less undertaken in the elderly. Malnutrition is prevalent in elderly patients with cancer, and more frequent than in younger patients. There is a need for an early integration of the nutritional counselling in patients with cancer, and particularly in the elderly. Copyright © 2017 Elsevier Ltd. All rights reserved.

Participation in an exercise intervention during cancer treatment diminishes the side effects associated with cancer therapies, although such benefits vary according to the disease and the patient characteristics. A structured exercise program providing an individualized fitness program tailored to the patients' illness, treatment, and fitness level would address this variability. However, the need, desired components, and anticipated barriers of such a program have not been systematically explored from either the point of view of cancer patients or treating oncologists. Sixty-six cancer patients and 18 medical and radiation oncologists were surveyed on the above variables. Cancer patients and oncologists alike perceived a need for a structured exercise program during and after medical treatment for cancer. Among cancer patients, the most commonly preferred feature was access to consultation with an exercise specialist who could take into account the patient's previous exercise and medical history. Over a third of patients reported interest in a hospital-based fitness program. Oncologists were in favor of appropriate supervision of patients during exercise, and noted insufficient time to discuss exercise in their practice. Respondents noted time and parking as barriers to participation. Overall, results support the need for a supervised exercise program during active treatment for cancer and highlight the desired features of such a program.

This study explored Iranian patients' experiences of cancer disclosure, paying particular attention to the ways of disclosure. Twenty cancer patients were invited to participate in this qualitative inquiry by research staff in the clinical setting. In-depth, semistructured interview data were analyzed through content analysis. The rigor of the study was established by principles of credibility, transferability, dependability, and confirmability. Four themes emerged: the atmosphere of non-disclosure, eventual disclosure, distress in knowing, and the desire for information. Non-disclosure was the norm for participants, and all individuals involved made efforts to maintain an atmosphere of non-disclosure. While a select few were informed of their diagnosis by a physician or another patient, the majority eventually became aware of their diagnosis indirectly by different ways. All participants experienced distress after disclosure. The participants wanted basic information about their prognosis and treatments from their treating physicians, but did not receive this information, and encountered difficulty accessing information elsewhere. These challenges highlight the need for changes in current medical practice in Iran, as well as patient and healthcare provider education. © 2012 Blackwell Publishing Asia Pty Ltd.

Acute limb ischemia in cancer patients: should we surgically intervene?

LENUS (Irish Health Repository)

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.

The best preoperative examination in Graves' disease with thyroid cancer still remains uncertain. The objectives of the present study were to investigate the prevalence of thyroid cancer in Graves' disease patients, and to identify the predictive factors and ultrasonographic features of thyroid cancer that may aid the preoperative diagnosis in Graves' disease. This retrospective study included 423 patients with Graves' disease who underwent surgical treatment from 2002 to 2012 at our institution. The clinical features and ultrasonographic findings of thyroid nodules were recorded. The diagnosis of thyroid cancer was determined according to the pathological results. Thyroid cancer was discovered in 58 of the 423 (13.7 %) surgically treated Graves' disease patients; 46 of those 58 patients had thyroid nodules, and the other 12 patients were diagnosed with incidentally discovered thyroid carcinomas without thyroid nodules. Among the 58 patients with thyroid cancer, papillary microcarcinomas were discovered in 50 patients, and multifocality and lymph node involvement were detected in the other 8 patients. Multivariate regression analysis showed younger age was the only significant factor predictive of metastatic thyroid cancer. Ultrasonographic findings of calcification and intranodular blood flow in thyroid nodules indicate that they are more likely to harbor thyroid cancers. Because the influencing factor of metastatic thyroid cancers in Graves' disease is young age, every suspicious nodule in Graves' disease patients should be evaluated and treated carefully, especially in younger patients because of the potential for metastasis.

Recently, the clinical and biological differences between right- and left-sided colon cancers have been widely debated. However, close analyses of these clinical differences, based on large-scale studies, have been scarcely reported. A total of 3552 consecutive Japanese colorectal cancer cases were examined and the clinical differences between right- and left-sided colon cancer cases were investigated. The proportion of right-sided colon cancer was relatively high in patients aged less than 40 years (33%) and more than 80 years (43%). The proportion of right-sided colon cancer in patients aged 40-59 years was relatively low (male 22% and female 29%). In male patients the proportion increased in the 70-79 years age group (30%), while in female patients the proportion increased in the 60-69 years age group (39%). Right-sided colon cancer was more likely to be detected at an advanced stage (T1 stage; left 22%, right 15%) (P cancer was dominant in the left colon (left 59%; right 40%) (P cancer in the right colon was significantly higher than that in the left colon (left 25%; right 44%) (P colon cancer was observed and the difference between male and female patients was highlighted. Other clinical features also differed between right- and left-sided colon cancer, suggesting that different mechanisms may be at work during right and left colon carcinogenesis.

The improved treatment protocols and subsequent improved survival rates among childhood cancer patients have shifted the focus toward the long-term consequences arising from cancer treatment. Children who have completed cancer treatment are at a greater risk of delayed development, diminished functioning, disability, compromised fundamental movement skill (FMS) attainment, and long-term chronic health conditions. The aim of the study was to compare FMS of childhood cancer patients with an aged matched healthy reference group. Pediatric cancer patients aged 5-8 years (n = 26; median age 6.91 years), who completed cancer treatment (<5 years) at the Sydney Children's Hospital, were assessed performing seven key FMS: sprint, side gallop, vertical jump, catch, over-arm throw, kick, and leap. Results were compared to the reference group (n = 430; 6.56 years). Childhood cancer patients scored significantly lower on three out of seven FMS tests when compared to the reference group. These results equated to a significantly lower overall score for FMS. This study highlighted the significant deficits in FMS within pediatric patients having completed cancer treatment. In order to reduce the occurrence of significant FMS deficits in this population, FMS interventions may be warranted to assist in recovery from childhood cancer, prevent late effects, and improve the quality of life in survivors of childhood cancer. © 2015 Wiley Periodicals, Inc.

Breast cancer patients often show an interest in making dietary changes after diagnosis of breast cancer to improve their health condition and prevent cancer recurrence. The objective of the study was to determine changes in dietary intake 2 years after diagnosis among breast cancer patients. One hundred sixteen subjects were asked to complete a semiquantitative food frequency questionnaire, diet recalls, and dietary changes questionnaire to assess dietary intake before and after diagnosis. The information on sociodemographic background, cancer treatment history, and anthropometric indices was also collected. Seventy-two subjects considered diet as a contributing factor to breast cancer, and 67 subjects changed their dietary habits after breast cancer diagnosis. The reasons for changes in diet were physician and dietitian advice and desire to cure cancer. The sources of information were derived from their physician, mass media, and family members. Total energy, protein, total fat, fatty acids, and vitamin E intake were significantly decreased after diagnosis. Meanwhile, the intake of β-carotene and vitamin C increased significantly after diagnosis. The changes included reduction in red meat, seafood, noodles, and poultry intake. An increased consumption of fruits, vegetables, fish, low-fat milk, and soy products was observed. The subjects tended to lower high-fat foods intake and started to eat more fruits and vegetables. Breast cancer patients had changed to a healthier diet after breast cancer diagnosis, although the changes made were small. This will be helpful to dietitians in providing a better understanding of good eating habits that will maintain patients' health after breast cancer diagnosis.

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

Radiation induced chromosomal instability in lymphocytes of cancer patients

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

D'Abramo, Flavio; Goerling, Ute; Guastadisegni, Cecilia

2016-04-01

Personalized medicine is a new field based on molecular biology and genomics in which targeted tumor therapies are administered to patients. Psycho-oncology is a complementary approach that considers social and psychological aspects of patients as part of the treatments for cancer patients. The aim of this mini-review is to weigh clinical benefits for breast cancer patients of both treatments and possibly enhance benefits by modulating the use of both interventions. We have compared and evaluated on the one hand the use of anti Vascular Endothelial Growth Factor and, on the other hand, psycho-oncological interventions in metastatic and non-metastatic breast cancer patients.Both treatments did not increase survival of metastatic breast cancer patients, while in a selected study psycho-oncological interventions extended lifespan of non-metastatic breast cancer patients and ameliorate psychological and social factors of metastatic breast cancer patients. Because the two approaches address completely different aspects of cancer patients, if the comparison is limited to the extension of survival, the value of these two treatments cannot be assessed and compared.It is likely that by comparing patients reported outcomes, possibly by using standardized Quality of Life questionnaires, both patients and health care providers can weigh the benefits of the two treatments. It is therefore important to evaluate the use of cancer patients' quality of life measures as a mean to improve their experiences about life and treatment, and possibly to extend their survival.

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.

Anemia, tumor hypoxemia, and the cancer patient

Varlotto, John; Stevenson, Mary Ann

2005-01-01

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. Radiosensitization through improvements in tumor oxygenation/hypoxic cell

Literature indicates that cancer patients experience high levels of unmet needs, particularly in relation to health information, psychological requirements and physical and daily living needs. It suggests that the needs of patients living in rural areas are likely to be higher than those of urban patients due to geographical factors and health service accessibility issues. This paper will explore the needs of cancer patients with particular focus on the impact of location (rural vs. urban), present the basis of these needs and identify strategies that address the needs expressed, by reviewing current literature.

2012-01-01

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.

131I therapy of thyroid cancer patients

International Nuclear Information System (INIS)

Reiners, C.; Farahati, J.

1999-01-01

Thyroid cancer is a rare malignancy with wide inter ethnic and geographic variations. In Germany thyroid carcinoma is the 13. most frequent malignancy (2.7 new cases yearly per 100,000 inhabitants). The overall temporal incidence is increasing slightly in recent years. The most common types of cancer are papillary (60-80%) and follicular cancers (10-20%). The relevant prognostic indicators are tumor stage and distant metastases. The mean survival rates in papillary thyroid cancer usually exceed 90%, whereas in follicular thyroid cancer they amount to approximately 80%. The standard treatment procedure in differentiated papillary and follicular thyroid cancer consists of total thyroidectomy followed by adjuvant ablative therapy with radioiodine. Only in papillary thyroid cancer stage pT 1 N 0 M 0 lobectomy alone is considered to be appropriate. In patients with locally invasive differentiated thyroid cancers stage pT 4 adjuvant percutaneous radiation therapy is a treatment option. Radioiodine therapy has to be performed under the stimulative influence of TSH. Usually TSH suppressive medication with Levothyroxine has to be withdrawn approximately 4 weeks prior to radioiodine therapy. In the future, exogenous stimulation by recombinant TSH may be used instead of thyroid hormone withdrawal. It has been proved by different studies that ablative radioiodine therapy reduces the frequency of recurrences and tumor spread in patients with thyroid cancer significantly. In patients with distant metastases, up to 50% of complete responses may be achieved with radioiodine treatment

When a patient is diagnosed with cancer, feelings such as fear, anxiety, and hopelessness can negatively affect a person's frame of mind. Hope can help a patient decrease anxiety and increase quality of life. Nurses should assess hope, provide interventions, be empathetic, listen, and treat patients with dignity to help improve hope and quality of life. This article features how hope can have a positive impact and provides specific information about how nurses can promote and foster hope in patients with cancer.

There is variability in physician practice regarding delivery method and timeliness of test results to cancer patients. Our aim was to survey patients to determine if there was a difference between actual and preferred care for disclosure of test results. A de-identified survey was distributed to online cancer support groups to query patients about their experience regarding communication of cancer testing and timeliness. Analyses of the differences between actual and preferred communication and wait times were performed. Overall, 1000 patients completed the survey. The analysis herein was restricted to 784 breast cancer survivors. Survey responders were predominately White (non-Hispanic; 89 %), college educated (78 %), and media 'savvy' (online medical media usage; 97 %). Differences between actual and preferred care were identified for the domains of mode of communication and wait times for initial breast cancer diagnostic biopsies and other tests. A total of 309 (39 %) of 784 patients received face-to-face communication for a new cancer diagnosis, with 394 (50 %) patients preferring this option (p cancer biopsy result within 2 days, with 646 (82 %) patients preferring this option (p < 0.0001). Differences were also identified between actual and preferred care for multiple other test types. Actual care for timeliness and modes of communication did not reflect patient-desired care. National and local initiatives to improve performance are needed. As a first step, we recommend that each patient be queried about their preference for mode of communication and timeliness, and efforts made to comply.

Long-term vocational achievements of 40 survivors of cancer diagnosed during adolescence were examined and compared with 40 healthy sex-matched and age-matched controls. Patients' ages at diagnosis ranged from 13 to 19 years (mean, 16.15). Study subjects had survived cancer for over 5 years and were on no cancer therapy. Assessment measures included the Rand General Well-Being Scale, the Rand Functional Limitations and Physical Abilities Batteries, and a semistructured interview. The relation of physical disability and limitations caused by cancer to patients' achievements also was evaluated. Although cancer patients, on the average, were more concerned about their health and reported lower general spirits than controls, no differences were found between control and study groups with regard to overall general well-being. More cancer patients than controls reported that their health limited their ability to engage in vigorous activities. A greater functional deficit was found among unemployed than employed cancer patients. Employers and co-workers often were aware of the patient's diagnosis (85% and 67%, respectively). Cancer patients reported disease-related discrimination in hiring (7.4%), induction into the military (66.7%), and obtaining health, life, and disability insurance (31.5%). There was no significant relationship between health status and employment. Nevertheless, cancer patients had a higher average income than controls. Sixty-four percent of patients believed that changes in certain physical features of the workplace were necessary to facilitate readjustment to the job. Despite the disabilities experienced by cancer patients and generally negative public attitudes, long-term survivors have a good outlook on life and are competitive members of the workplace and society.

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.

Hope is important to cancer patients as it helps them deal with their diagnosis. Little is known about hope in newly diagnosed cancer patients. Based on the Transcending Possibilities conceptual model of hope, the purpose of this study was to examine the relationship of hope with pain, energy, and psychological and demographic characteristics in newly diagnosed adult oncology outpatients. Data from 310 New Patient Assessment Forms from cancer outpatients' health records were collected. Health records from the first six months of 2009 were reviewed and data were collected on hope, energy, pain, depression, anxiety, feeling overwhelmed, and demographic variables. A generalized linear modeling approach was used to study the relationship of hope scores with these variables. Hypothesized variables and variables that were significant at the P = 0.01 level from the univariate analysis were entered into the multivariate model, with hope scores as the dependent variable. Hope scores were significantly negatively related to age (P = 0.02). More specifically, oncology patients who were 65 years of age or older had significantly less hope than those under the age of 65 years (P = 0.01). Gender (P = 0.009) also was a significant factor, with men having higher hope scores than women. No other variables were significant. Older adults comprise the majority of persons in Canada with cancer. The lower hope scores found in this age group compared with their younger counterparts underscore the importance of further research. This study provides a foundation for future research in this important area for oncology patients. Copyright © 2013 U.S. Cancer Pain Relief Committee. Published by Elsevier Inc. All rights reserved.

Lung cancer is globally the leading cause of cancer-related deaths. Majority of lung cancer cases is diagnosed in elderly patients, aged ≥65 years. In Slovakia, 54% of new lung cancer cases are diagnosed in patients aged ≥65 years, and about 40% in patients aged ≥70 years. An experts panel created by EORTC (European Organisation for Research and Treatment of Cancer) and ISGO (International Society for Geriatric Oncology) published in 2014 updated recommendations for treatment of elderly patients with non-small-cell lung cancer. The brief overview of these recommendations, including a view of the new data published since 2014, is given in this article. (author)

Gynecological cancer survivors are at increased risk of psychological problems including suicide risk. Suicidal ideation, which was thought to be precursor to suicide attempts, has not been well studied. This study aimed to investigate the prevalence, and determinants of suicidal ideation for women with gynecological cancer, and then to assess the effect of coping style and social support on suicidal ideation. Patients with cervical, ovarian and endometrial cancers seen at Hunan Provincial Tumor Hospital from September 2012 to June 2013 were consecutively recruited and were asked to complete the Zung Self-Rating Depression Scale, Suicidal Ideation of Self-rating Scale, Medical Coping Modes Questionnaire and Social Support Rating Scale. Path analysis was used to examine the relationship among coping style, social support, depression symptoms and suicidal ideation. A total of 579 (579/623, 93.0%) gynecological cancer patients were enrolled in this study and completed all investigations between September 2012 and June 2013. Among them, 105 (18.1%) patients reported suicidal ideation, with the highest rate in patients with ovarian cancer (30.16%). Suicidal ideation was associated with depression symptoms, care providers, chemotherapy history and acceptance-resignation. Path analysis showed that the acceptance-resignation affected suicidal ideation directly as well as mediated by social support and depression symptoms, while confrontation and avoidance affected suicidal ideation entirely through social support and depression symptoms. Suicidal ideation is high among patients with gynecological cancer, especially among ovarian cancer patients. Coping strategies such as confrontation and avoidance, and social support may be helpful for preventing suicidal ideation among them. Copyright © 2015 John Wiley & Sons, Ltd.

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

A Patient-Centered Perspective on Cancer Survivorship

Directory of Open Access Journals (Sweden)

Brad Zebrack

2015-04-01

Full Text Available Survivorship is a complicated notion because people often confuse a process of survivorship with a mythic identity of being a cancer survivor. This confusion may be a distraction to addressing the real-life struggles and challenges experienced by all people diagnosed with cancer. A more expansive perspective of survivorship, one that attends to patients’ physical, psychological, social, spiritual, and existential challenges throughout a continuum of care, would be more in line with what is known empirically about people’s experiences with cancer. In an effort to gain a patient-centered perspective on cancer, and one that emphasizes multiple dimensions of cancer survivorship, the author reports findings from a non-scientific social media poll (via Facebook and personal emails in which survivors and colleagues working in the field of cancer survivorship answered the question: What does cancer survivorship mean to you? The comments are enlightening and useful for guiding the development of a patient-centered, and, thus, more comprehensive, approach to caring for people affected by cancer.

CANCER IN OTHER WORDS? THE ROLE OF METAPHOR IN EMOTION DISCLOSURE IN CANCER PATIENTS.

Lanceley, Anne; Clark, Jill Macleod

2013-05-01

Despite evidence that nurses may play a crucial part in the wellbeing and recovery of cancer patients by facilitating their expression of feelings, research is lacking into the emotional content of nurse-patient talk and patients' use of language in emotion disclosure. In this study, 23 participating nurses in a variety of cancer care settings were asked to tape-record their conversations with patients during daily care. A data set of 60 nurse-patient conversations was collected. Individual expression of emotion by patients was identified through interpretive literary analysis within a framework of psychodynamic theory. Overall the picture of emotion disclosure was intense. In particular, patients' use of metaphor and figurative language to express their distress was powerful and pervasive. Participating nurses demonstrated responsive skills but their responses to figurative expression were often problematic. The study provides evidence of unconscious processes in nurses' work and advocates career-long psychoanalytically informed supervision for nurses to better support them in challenging dialogue with cancer patients. Research is needed to evaluate the impact of supervision on communications with cancer patients to ensure patients have access to appropriate emotional supportive and care.

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)

Cancer patients diagnosed with type 2 diabetes mellitus (T2DM) are at an increased risk of death due to cancer. However, whether T2DM comorbidity increases other causes of death in cancer patients is the novel theme of this study. Patients with T2DM were identified from the nationwide Swedish Hospital Discharge Register and linked with patients with cancer recorded from the Swedish Cancer Registry. Hazard ratios (HRs) were calculated for death due to all causes among cancer patients with and without T2DM; both underlying and multiple causes of death were examined using the Cox regression model. A total of 13 325 cancer patients were identified with comorbidity of T2DM. The total number of deaths of cancer patients was 276 021. Of these, 5900 occurred after T2DM diagnosis. For underlying causes of death, except for T2DM, the highest cause-specific HRs were found for complications of bacterial disease (HR, 3.93; 95% CI, 3.04-5.09), urinary system disease (HR, 3.39; 95% CI, 2.78-4.12), and myocardial infarction (HR, 2.93; 95% CI, 2.75-3.12). When risk of death was examined for both underlying and multiple causes of death, the highest HRs were found for hypertensive disease (HR, 3.42; 95% CI, 3.15-3.72), urinary system disease (HR, 3.39; 95% CI, 3.17-3.63), and arterial disease (HR, 3.26; 95% CI, 3.08-3.46). The diagnosis of T2DM in cancer patients is associated with an increased risk of death due to various causes, including myocardial infarction, other bacterial disease, urinary system disease, hypertensive disease, arterial disease, and so on, which may be related to both cancer and treatment. Clinicians that treat cancer patients with T2DM should pay more attention to comorbidities.

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.

There is little known about illness perception in patients with skin tumors. We conducted this study to investigate Iranian patients' understanding of skin tumors, and to evaluate their sun-protective behavior changes after treatment of skin cancer. Patients with a skin biopsy of basal cell carcinoma were asked to complete questionnaires. A total of 110 patients were enrolled in the study. Patients were mostly referred to our tumor clinic from rural areas. At the skin cancer perception investigation, 63% of patients did not consider their disease as a long-lasting situation. Besides, 45.4% of patients consider their illness as a serious condition which significantly affecting their lives. Our patients had a strong belief in treatment control (81%) and 81% of them also described worries about their skin cancer. The leading causes of skin cancer as assumed by patients were: history of skin cancer (37.4%), poor medical care in the past (36.4%), extreme sun exposure (31.5%), and lack of sun protection (27.5%). In regard to sun-protective behavior after treatment of skin cancer, 55.4% of patients showed no changes or even negative change in their sun-protective behavior, But 44.5% of the patients changed their sun-protective behavior in a positive way which was statically significant (P ≤ 0.001). Our study demonstrates how our patients with skin cancer perceive their disease and we need to educate our patients, considering diseases' aspects, causes and symptoms. This is of great value as dermatologists should be aware of patients' perceptions of their disease in order to improve patients' knowledge through educating more about different aspects of disease.

Cancer can have a serious impact on patient well-being and quality of life. The international literature reports a higher prevalence of psychosocial problems among cancer patients; primarily problems associated with difficulties in the family, duties in the household, work and leisure, sexuality and finances. The prevalence of these problems among Danish cancer patients is still unknown. A questionnaire assessing psychosocial problems and needs was mailed out to all patients who had been at the Department of Oncology, Aarhus Hospital in week 35, 2004. A total of 71%, i.e. 515 patients (34% men and 66% women) in active treatment and control returned the questionnaire. High levels of emotional distress were reported by 39% of the patients. High levels of distress were primarily related to problems with worries about their spouses, household duties, financial problems and experiences of insufficient collaboration between health care and social services. Between 19% and 25% of the patients required further help to handle emotional problems, legal and financial problems and practical problems in the home. A considerable proportion of oncology patients experience significant levels of distress. This group of distressed patients also report unmet needs for psychosocial support.

Optimal patient decision making requires integration of patient values, goals, and preferences with information received from the physician. In the case of a life-threatening illness such as cancer, the weights placed on quality of life (QOL) and length of life (LOL) represent critical values. The objective of the current study was to describe cancer patient values regarding QOL and LOL and explore associations with communication preferences. Patients with advanced cancer completed a computer-based survey before the initial consultation with a medical oncologist. Assessments included sociodemographics, physical and mental health state, values regarding quality and length of life, communication preferences, and cancer-related distress. Among 459 patients with advanced cancer, 55% placed equal valued on QOL and LOL, 27% preferred QOL, and 18% preferred LOL. Patients with a QOL preference had lower levels of cancer-related distress (P LOL over QOL desired a more supportive and less pessimistic communication style from their oncologists. These data indicate that a values preference for LOL versus QOL may be simply measured, and is associated with wishes regarding the nature of oncologist communication. Awareness of these values during the clinical encounter could improve decision making by influencing the style and content of the communication between oncologists and their patients.

Weight loss and malnutrition are common among cancer patients, these two factors greatly affecting survival and quality of life during treatment. Since cancer is becoming increasingly common in the world and in order to provide better treatment measures, it is important to identify and prevent side effects. The present study has been conducted in 2010 on a sample of cancer patients in the oncology center of Shahid Beheshti University of Medical Sciences to determine the prevalence rates of malnutrition and the factors affecting it. The PG-SGA standard questionnaire was administered to 416 cancer patients to evaluate their nutrition status and determine the frequency of each malnutrition stage. Correlations and ANOVA tests were used to analyze the relationship between factors and weight loss and how they might affect the development of malnutrition. The prevalence of malnutrition among the patients was 53.1% out of which 29.1% had moderate and 24% had severe malnutrition. The most common factors inducing nutritional symptoms were depression and anorexia. Some 35 % of the patients had over 5% weight loss in the last mouth. The average PG-SGA score was 10.1 with 49 being the highest. 46.1 percent of the patients scored over 9 (requiring critical nutrient intervention). Malnutrition has a high correlation with weight loss, activity limitations, nutritional symptoms, and cancer stage, but low correlation with treatment and pathologic type. Malnutrition has a high prevalence in Iranian cancer patients and has a close relationship with mortality, morbidity and treatment-related problems and also quality of life. Therefore, periodical assessment by PG-SGA to detect malnutrition in patients should be made so that appropriate nutritional interventions can be provided.

Complementary and alternative medicine (CAM) for treatment of cancer and for supportive care of cancer patients must be clearly separated. There is encouraging evidence for CAM in the latter area, such as acupuncture and progressive muscle relaxation for chemotherapy-related nausea and vomiting, and aromatherapy for decreasing anxiety and increasing quality of life. However, there are limited data about CAM used by gynecologic cancer patients, especially in Thai women. Therefore, the authors aimed to investigate the proportion and types of CAM using in our gynecologic cancer patients. This cross-sectional survey was conducted between October to December, 2008. Totals of 50 admitted and 50 walk-in gynecologic cancer patients 1 month after diagnosis, aged more than 20 years and able to give informed consent, were selected for one-by-one interview by random walking survey. Among the 100 interviewed patients, aged 21-69 (mean=50.12), there were 46 cases of cervical cancers, 35 of ovarian cancers, 18 of endometrial cancers (two of these also had ovarian cancers), 2 of malignant gestational trophoblastic diseases, 1 of vulvar cancer, and 1 liver cancer (in a patient with ovarian cancer). Some 67% (95% CI, 57.8-76.2%) of them used CAM. As diet modifications, 11 used Chinese vegetarian, 8 common vegetarian, 5 Cheewajit, and 1 macrobiotics. Five of them used dietary supplements while colonic detoxification was emplyed in three. As herbal medicines, 27 used Thai herbs, 4 Chinese herbs, and 1 a herbal sauna. Twelve were receiving Thai massage. As exercises, 23 used aerobics and 5 stretching. Interestingly, 62 of them used Buddhist praying while only 3 employed native magic. The three most common forms of CAM used by our gynecologic cancer patients were Buddhist praying (62/67, 92.5%), followed by herbal medicines (27/67, 40.3%) and exercises (25/67, 37.3%).

The widespread use of the recently introduced multi-detector CT scanners has resulted in an increasing number of incidentally diagnosed pulmonary embolism (PE in asymptomatic cancer patients. The significance and clinical outcome of such incidental PE is described.Methods: Both radiology department and hospital databases were searched for all cancer patients with a diagnosis of incidental PE. CT scans were performed using a 64-slice scanner with a 5.0 mm slice thickness.Results: During the study period, 34 patients with incidental PE were identified. The mean age (±SD was 57.7 (±12.4 years. All patients had active cancer, gastric, lung, colorectal, and lymphomas being the most frequent. Most patients had advanced-stage disease at the time of PE diagnosis; 26 (77% patients had stage IV, whereas only 3 patients had stages I or II disease. Twenty-seven (79% patients had their PE while undergoing active treatment with chemotherapy (68% or radiotherapy (12%; none, however, were on hormonal therapy. Most (74% patients had their PE diagnosed without history of recent hospital admission. Except for 5 (15%, all other patients were anticoagulated. With follow-up, 2 patients developed recurrent PE, 2 others had clinical and echocardiographic evidence of pulmonary hypertension, and 9 (26% died suddenly within 30 days of the diagnosis of incidental PE; 2 of these where among the 5 patients who were not anticoagulated.Conclusion: Incidental PE in cancer patients is increasingly encountered. Similar to symptomatic PE, many were diagnosed in patients with advanced stage disease and while undergoing active anti-cancer therapy. A significant percentage of patients had recurrent emboli, pulmonary hypertension

The data of an epidemiologic study of multiple primary malignant neoplasms in breast cancer patients in Israel are presented. During the 18-year period of the study 12,302 cases of breast carcinoma were diagnosed, and, of these, 984 patients (8%) had multiple primary malignant tumors. Forty-seven of these patients developed two multiple primary cancers. A significantly higher than expected incidence of second primary cancers occurred at the following five sites: the opposite breast, salivary glands, uterine corpus, ovary, and thyroid. Cancers of the stomach and gallbladder were fewer than expected. Treatment of the breast cancer by irradiation was associated with an increased risk of subsequent cancers of lung and hematopoietic system. The prognosis was mainly influenced by the site and malignancy of the second primary cancer. The incidence of multiple primary malignancies justifies a high level of alertness to this possibility in the follow-up of breast cancer patients

Purpose: Patient-centered communication is critical to quality cancer care. Effective communication can help patients and family members cope with cancer, make informed decisions, and effectively manage their care; suboptimal communication can contribute to care breakdowns and undermine clinician-patient relationships. The study purpose was to explore stakeholders' views on the feasibility and acceptability of collecting self-reported patient and family perceptions of communication experiences while receiving cancer care. The results were intended to inform the design, development, and implementation of a structured and generalizable patient-level reporting system. Methods: This was a formative, qualitative study that used semistructured interviews with cancer patients, family members, clinicians, and leaders of health care organizations. The constant comparative method was used to identify major themes in the interview transcripts. Results: A total of 106 stakeholders were interviewed. Thematic saturation was achieved. All stakeholders recognized the importance of communication and endorsed efforts to improve communication during cancer care. Patients, clinicians, and leaders expressed concerns about the potential consequences of reports of suboptimal communication experiences, such as damage to the clinician-patient relationship, and the need for effective improvement strategies. Patients and family members would report good communication experiences in order to encourage such practices. Practical and logistic issues were identified. Conclusion: Patient reports of their communication experiences during cancer care could increase understanding of the communication process, stimulate improvements, inform interventions, and provide a basis for evaluating changes in communication practices. This qualitative study provides a foundation for the design and pilot testing of such a patient reporting system. PMID:23943884

Physical symptoms related to cancer are associated with various mental conditions. An adopted attitude towards pain and disease affects the quality of life of patients and may even decide about the final outcome of therapy. The objective of the study was to assess the degree of mental adjustment of patients diagnosed with breast, lung, colorectal and prostate cancer. The analysis also covered the effect of socioeconomic factors on mental adjustment in patients in the above groups. The study included 902 patients treated on an outpatient basis at the Center of Oncology, the Maria Skłodowska-Curie Institute in Warsaw, in the year 2013. The study participants were patients diagnosed with breast, lung, colorectal and prostate carcinoma. The Paper and Pencil Interview (PAPI) technique was applied. The questionnaire interview included demographic-type questions (socioeconomic variables) and the Mini-Mental Adjustment to Cancer (mini-MAC) scale, which measures the degree of mental adjustment to disease. The highest scores in the anxious preoccupation and helplessness-hopelessness subclasses were those of the lung, colorectal, breast and prostate cancer patients. In breast and lung cancer study participants, differences between individual categories distinguished due to socioeconomic features proved statistically insignificant. However, significant dependencies were observed between mental adjustment to disease and chemotherapy in the past year; though, the results differ with respect to the primary site. The primary site affects patient adjustment to disease. Socioeconomic factors in the area of mental adaptation differentiate colorectal carcinoma patients.

Full Text Available Hepatic infarction is known as a rare disease entity in nontransplant patients. Although a few cases of hepatic infarction have been reported to be linked with invasive procedures, trauma, and hypercoagulability, a case of spontaneous hepatic infarction in a nontransplanted patient has hardly ever been reported. However, many clinical situations of patients with cancer, in particular biliary cancer, can predispose nontransplant patients to hepatic infarction. Besides, the clinical outcome of hepatic infarction in patients with cancer can be worse than in patients with other etiologies. As for treatment, anticoagulation treatment is usually recommended. However, because of its multifactorial etiology and combined complications, treatment of hepatic infarction is difficult and not simple. Herein, we report a case of fatal hepatic infarction that occurred spontaneously during the course of treatment in a patient with gallbladder cancer. Hepatic infarction should be considered as a possible fatal complication in patients during treatment of biliary malignancies.

Combined pulmonary fibrosis and emphysema (CPFE) patients may be at significantly increased risk of lung cancer compared with either isolated emphysema or pulmonary fibrosis patients. Acute exacerbation (AE) of interstitial lung disease caused by anticancer treatment is the most common lethal complication in Japanese lung cancer patients. Nevertheless, the clinical significance of CPFE compared with isolated idiopathic interstitial pneumonias (IIPs) in patients with lung cancer is not well understood. A total of 1536 patients with lung cancer at Nippon Medical School Hospital between March 1998 and October 2011 were retrospectively reviewed. Patients with IIPs were categorized into two groups: (i) CPFE; IIP patients with definite emphysema and (ii) non-CPFE; isolated IIP patients without definite emphysema. The clinical features, anti-cancer treatments and outcomes of the CPFE group were compared with those of the non-CPFE group. CPFE and isolated IIPs were identified in 88 (5.7%) and 63 (4.1%) patients respectively, with lung cancer. AE associated with initial treatment occurred in 22 (25.0%) patients in the CPFE group and in 8 (12.7%) patients in the non-CPFE group, irrespective of treatment modality. Median overall survival (OS) of the CPFE group was 23.7 months and that of the non-CPFE group was 20.3 months (P=0.627). Chemotherapy was performed in a total of 83 patients. AE associated with chemotherapy for advanced lung cancer occurred in 6 (13.6%) patients in the CPFE group and 5 (12.8%) patients in the non-CPFE group. Median OS of the CPFE group was 14.9 months and that of the non-CPFE group was 21.6 months (P=0.679). CPFE was not an independent risk factor for AE and was not an independent prognosis factor in lung cancer patients with IIPs. Therefore, great care must be exercised with CPFE as well as IIP patients when performing anticancer treatment for patients with lung cancer. Copyright © 2014 Elsevier Ireland Ltd.

The objectives of this study were to compare the importance of components of a good death among cancer patients, the general population, oncologists, and oncology nurses, and explore which patients preferred "fighting against cancer." We conducted a cross-sectional anonymous self-reported survey of cancer patients who visited a radiation oncology outpatient clinic, oncologists, and oncology nurses at the Tokyo University Hospital and a random sample of the general population in the Tokyo metropolitan area. The outcomes were 18 previously developed components of a good death in Japanese cancer care consisting of 57 attributes. Three hundred ten patients, 353 subjects from the general population, 109 oncologists, and 366 oncology nurses participated. The desire to "fight against cancer" was highly significantly different between patients and oncologists (effect size [ES] = -1.40; P = 0.001) and patients and oncology nurses (ES = -1.12; P = 0.001). "Physical and cognitive control" was, similarly, highly significantly different between patients and oncologists (ES = -1.30; P = 0.001) and patients and oncology nurses (ES = -1.06; P = 0.001). Patients who emphasized "maintaining hope and pleasure" (P = 0.0001), "unawareness of death" (P = 0.0001), and "good relationship with family" (P = 0.004) favored "fighting against cancer." The patients, however, who emphasized "physical and psychological comfort" did not significantly favor "fighting against cancer" (P = 0.004). The importance of good death components differed between groups. Medical professionals should be aware of the diversity of values surrounding death and assess the patient's values and discuss them to support his or her quality of life. In addition, the development of care and a medical/social system to maintain hope and pleasure after failure of anticancer treatment is necessary.

Improved management of colorectal cancer patients has resulted in better five-year survival for rectal cancer compared with colon cancer. We compared excess mortality rates in various time intervals after surgery in patients with colon and rectal cancer. We analysed all patients with curative resection of colorectal cancers reported in the Cancer Registry of Norway before (1994-1996) and after (2001-2003) national treatment guidelines were introduced. Excess mortality was analysed in different postoperative time intervals within the five-year follow-up periods for patients treated in 1994-1996 vs. 2001-2003. A total of 11 437 patients that underwent curative resection were included. For patients treated from 1994 to 1996, excess mortality was similar in colon and rectal cancer patients in all time intervals. For those treated from 2001 to 2003, excess mortality was significantly lower in rectal cancer patients than in colon cancer patients perioperatively (in the first 60 days: excess mortality ratio = 0.46, p = 0.007) and during the first two postoperative years (2-12 months: excess mortality ratio = 0.54, p = 0.010; 1-2 years: excess mortality ratio = 0.60, p = 0.009). Excess mortality in rectal cancer patients was significantly greater than in colon cancer patients 4-5 years postoperatively (excess mortality ratio = 2.18, p = 0.003). Excess mortality for colon and rectal cancer changed substantially after the introduction of national treatment guidelines. Short-term excess mortality rates was higher in colon cancer compared to rectal cancer for patients treated in 2001-2003, while excess mortality rates for rectal cancer patients was significantly higher later in the follow-up period. This suggests that future research should focus on these differences of excess mortality in patients curatively treated for cancer of the colon and rectum.

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

Neural response during the activation of the attachment system in patients with borderline personality disorder: An fMRI study

Directory of Open Access Journals (Sweden)

Full Text Available 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. Eleven female patients with BPD without posttraumatic stress disorder and seventeen healthy female controls matched for age and education were telling stories in the scanner in response to the Adult Attachment Projective Picture System, 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 two minutes. 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 and the rostral cingulate zone. 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.

Cancer risk at low doses of ionizing radiation. Artificial neural networks inference from atomic bomb survivors

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 (1) the presence of a threshold that varied with organ, gender and age at exposure, and (2) 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.

BACKGROUND American Indians/Alaskan Natives (AI/ANs) have the worst 5-year cancer survival of all racial/ethnic groups in the United States. Causes for this disparity are unknown. The authors of this report examined the receipt of cancer treatment among AI/AN patients compared with white patients. METHODS This was a retrospective cohort study of 338,204 patients who were diagnosed at age ≥65 years with breast, colon, lung, or prostate cancer between 1996 and 2005 in the Surveillance, Epidemiology, and End Results-Medicare database. Nationally accepted guidelines for surgical and adjuvant therapy and surveillance were selected as metrics of optimal, guideline-concordant care. Treatment analyses compared AI/ANs with matched whites. RESULTS Across cancer types, AI/ANs were less likely to receive optimal cancer treatment and were less likely to undergo surgery (P ≤ .025 for all cancers). Adjuvant therapy rates were significantly lower for AI/AN patients with breast cancer (P <.001) and colon cancer (P = .001). Rates of post-treatment surveillance also were lower among AI/ANs and were statistically significantly lower for AI/AN patients with breast cancer (P = .002) and prostate cancer (P <.001). Nonreceipt of optimal cancer treatment was associated with significantly worse survival across cancer types. Disease-specific survival for those who did not undergo surgery was significantly lower for patients with breast cancer (hazard ratio [HR], 0.62), colon cancer (HR, 0.74), prostate cancer (HR, 0.52), and lung cancer (HR, 0.36). Survival rates also were significantly lower for those patients who did not receive adjuvant therapy for breast cancer (HR, 0.56), colon cancer (HR, 0.59), or prostate cancer (HR, 0.81; all 95% confidence intervals were <1.0). CONCLUSIONS Fewer AI/AN patients than white patients received guideline-concordant cancer treatment across the 4 most common cancers. Efforts to explain these differences are critical to improving cancer care and

Preparing patients with cancer who work and treatment responsiveness.

Kamau, Caroline

Many patients with life-limiting illnesses continue to work because of financial reasons and because work provides good psychosocial support. A lack of appropriate advice/support through patient education could, however, make having a job detrimental to well-being (eg, symptom worsening). This study investigated the frequency with which patients received information that empowers their understanding of their condition, treatment, side effects of treatment and the likely impact on occupational functioning. A cross-sectional study. An analysis of survey data from 3457 patients with cancer in employment. Logistic regression showed that patients who received information about the impact of cancer on work life or education are 1.72 times more likely to have a positive treatment outcome. Patients who receive written information about the type of cancer are 1.99 times more likely to have a positive treatment outcome. Also, patients who receive written information before a cancer-related operation are 1.90 times more likely to have a positive treatment outcome. Information about the side effects of cancer treatment produces worse odds of a positive treatment outcome (0.65-1). A stepwise logistic regression analysing the effects irrespective of current employment status in 6710 patients showed that preparing them produces nearly twice better odds of cancer treatment responsiveness. Palliative care teams should consider ways of actively advising patients who work. Whereas the results showed evidence of good practice in cancer care, there is a need to ensure that all working patients with potentially life-limiting illnesses receive similar support.
