    Full Text Available Abstract Background Korea achieved universal health insurance coverage in only 12 years; however, insufficient government funding has resulted in high out-of-pocket payments and, in turn, a demand for supplementary private health insurance (PHI. Supplementary PHI provides a fixed amount of benefits in the event of critical illness (e.g., cancer or stroke, surgery, or hospitalization. In this study, we tried to identify factors that influence the decision to purchase supplementary PHI and investigate the impacts of PHI on various aspects of cancer care. Methods In a cross-sectional study of 391 patients with gastric cancer, we collected data on demographic and clinical variables, coverage by PHI at the time of diagnosis, and patients' cancer care experiences from surgery databases and patient questionnaires. Two separate multivariate logistic regression models were used 1 to determine whether various sociodemographic and clinical variables influence the purchase of supplementary PHI, and 2 to determine if there is a difference in various outcome measures between individuals with and without PHI. Results We studied 187 subjects (49.6% who were covered under PHI at the time of diagnosis. Subjects who purchased PHI tended to be younger (aOR = 5.01, 95% C.I. = 2.05 – 12.24, and more educated (aOR = 2.67, 95% C.I. = 1.04 – 6.86. Supplementary PHI coverage was significantly associated with financial independence (aOR = 2.07, 95% CI = 1.19 – 3.61, but not with other aspects of cancer care, such as access to healthcare, quality of care, communication and patient autonomy. Conclusion Our findings demonstrate that supplementary PHI neither serves as a safety net for vulnerable patients nor improves cancer care experience, except for maintaining the financial independence of beneficiaries.

    OBJECTIVE Supplementary motor area (SMA) epilepsy is a well-known clinical condition; however, long-term surgical outcome reports are scarce and correspond to small series or isolated case reports. The aim of this study is to present the surgical results of SMA epilepsy patients treated at 2 reference centers in Mexico City. METHODS For this retrospective descriptive study (1999-2014), 52 patients underwent lesionectomy and/or corticectomy of the SMA that was guided by electrocorticography (ECoG). The clinical, neurophysiological, neuroimaging, and pathological findings are described. The Engel scale was used to classify surgical outcome. Descriptive statistics, Student t-test, and Friedman, Kruskal-Wallis, and chi-square tests were used. RESULTS Of these 52 patients, the mean age at epilepsy onset was 26.3 years, and the mean preoperative seizure frequency was 14 seizures per month. Etiologies included low-grade tumors in 28 (53.8%) patients, cortical dysplasia in 17 (32.7%) patients, and cavernomas in 7 (13.5%) patients. At a mean follow-up of 5.7 years (range 1-10 years), 32 patients (61%) were classified as Engel Class I, 16 patients (31%) were classified as Engel Class II, and 4 (8%) patients were classified as Engel Class III. Overall seizure reduction was significant (p = 0.001). The absence of early postsurgical seizures and lesional etiology were associated with the outcome of Engel Class I (p = 0.05). Twenty-six (50%) patients had complications in the immediate postoperative period, all of which resolved completely with no residual neurological deficits. CONCLUSIONS Surgery for SMA epilepsy guided by ECoG using a multidisciplinary and multimodality approach is a safe, feasible procedure that shows good seizure control, moderate morbidity, and no mortality.

  3. Supplementary insurance as a switching cost for basic health insurance: Empirical results from the Netherlands.

    Nearly everyone with a supplementary insurance (SI) in the Netherlands takes out the voluntary SI and the mandatory basic insurance (BI) from the same health insurer. Previous studies show that many high-risks perceive SI as a switching cost for BI. Because consumers' current insurer provides them with a guaranteed renewability, SI is a switching cost if insurers apply selective underwriting to new applicants. Several changes in the Dutch health insurance market increased insurers' incentives to counteract adverse selection for SI. Tools to do so are not only selective underwriting, but also risk rating and product differentiation. If all insurers use the latter tools without selective underwriting, SI is not a switching cost for BI. We investigated to what extent insurers used these tools in the periods 2006-2009 and 2014-2015. Only a few insurers applied selective underwriting: in 2015, 86% of insurers used open enrolment for all their SI products, and the other 14% did use open enrolment for their most common SI products. As measured by our indicators, the proportion of insurers applying risk rating or product differentiation did not increase in the periods considered. Due to the fear of reputation loss insurers may have used 'less visible' tools to counteract adverse selection that are indirect forms of risk rating and product differentiation and do not result in switching costs. So, although many high-risks perceive SI as a switching cost, most insurers apply open enrolment for SI. By providing information to high-risks about their switching opportunities, the government could increase consumer choice and thereby insurers' incentives to invest in high-quality care for high-risks.

    Full Text Available Purpose: Dysphagia is a common initial presentation in locally advanced esophageal cancer and negatively impacts patient quality of life and treatment compliance. To induce fast relief of dysphagia in patients with potentially operable esophageal cancer high-dose-rate (HDR brachytherapy was applied prior to definitive radiochemotherapy. Material and methods : In this single arm phase II clinical trial between 2013 to 2014 twenty patients with locally advanced esophageal cancer (17 squamous cell and 3 adenocarcinoma were treated with upfront 10 Gy HDR brachytherapy, followed by 50.4 Gy external beam radiotherapy (EBRT and concurrent chemotherapy with cisplatin/5-fluorouracil. Results : Tumor response, as measured by endoscopy and/or computed tomography scan, revealed complete remission in 16 and partial response in 4 patients (overall response rate 100%. Improvement of dysphagia was induced by brachytherapy within a few days and maintained up to the end of treatment in 80% of patients. No differences in either response rate or dysphagia resolution were found between squamous cell and adenocarcinoma histology. The grade 2 and 3 acute pancytopenia or bicytopenia reported in 4 patients, while sub-acute adverse effects with painful ulceration was seen in five patients, occurring after a median of 2 months. A perforation developed in one patient during the procedure of brachytherapy that resolved successfully with immediate surgery. Conclusions : Brachytherapy before EBRT was a safe and effective procedure to induce rapid and durable relief from dysphagia, especially when combined with EBRT.

    Full Text Available Background. Phase I of this study was aimed at comparing the profiles of oxidative stress biomarkers in patients with history of nonmelanoma skin cancer (NMSC, previously treated with surgery, to the healthy subjects. Phase II aimed to evaluate the effects of supplementary antioxidant therapy on the levels of biomarkers in the case group. Materials and Methods. In Phase I, oxidative stress biomarkers were measured in blood samples obtained from 24 healthy subjects and 60 patients with history of NMSC previously treated with surgery. In Phase II, the 60 patients with history of NMSC were randomized into two subgroups, one receiving placebo (n=34 and the other (n=26 receiving vitamin C, vitamin E, and zinc supplementation for 8 weeks, followed by reevaluation of biomarkers. Results. In Phase I, patients with history of NMSC showed increased plasma concentrations of all biomarkers, but only 15-F2t-isoprostane was significantly higher than in the healthy subjects. Risk of NMSC increased by 4% for each additional 1 pg/mL increase in 15-F2t-isoprostane. In Phase II, supplementation did not significantly reduce levels of oxidative stress biomarkers. Conclusion. Patients with history of NMSC had significantly high 15-F2t-isoprostane plasma levels; supplementation did not result in significant reduction of oxidative stress biomarkers. This trial was registered with ClinicalTrials.gov (ID NCT02248584.

    Background Most gastric cancer patients who undergo gastrectomy develop malnutrition.It is,therefore,crucial to establish an effective means to provide nutrition for these patients.To perform home enteral nutrition (EN) to ensure adequate nutritional intake in gastric cancer patients,we placed a jejunostomy catheter during gastric surgery.Most patients showed improved nutritional status.Methods Twenty-nine inpatients at our hospital underwent radical gastrectomy and jejunostomy from December 2002 to December 2007 and were designated as the jejunostomy group,and 32 matched patients without a jejunostomy tube were designated as the tube-free group.The jejunostomy group was treated with EN from 72 hours to 3 months postoperatively.The tube-free group did not receive EN.Data including preoperative and postoperative body weight,body mass index (BMI),nutrition risk screening (NRS) score,Karnofsky performance score (KPS),and laboratory biochemical indicators were documented respectively and compared.Results Compared with preoperative week 1,both groups showed decreased body weight and BMI at 3 months postoperatively.The weight loss in the jejunostomy group ((7.1±3.3) kg) was significantly less than that in the tube-free group ((9.9±3.1) kg).Similarly,BMI decreased by (2.4+1.0) kg/m2 in the jejunostomy group,which was significantly less than in the tube-free group ((3.2±0.9) kg/m2).The number of patients with postoperative NRS ≥3 was decreased in the jejunostomy group,but was increased in the tube-free group,and this difference was significant.There were no significant differences between the two groups in total lymphocyte count,hemoglobin,albumin and prealbumin,and adverse drug effects.Conclusions Short-term (3 months) EN supplementation via jejunostomy tube can reduce the risk of malnutrition and weight loss,and improve tolerance of chemotherapy.Tube feeding is reliable for achieving these goals because it is not important whether or not the patients have appetites.

    Esophageal fistula is a critical adverse event in patients treated with chemoradiotherapy (CRT) for locally advanced esophageal cancer. However, risk factors associated with esophageal fistula formation in patients receiving CRT have not yet been elucidated.We retrospectively analyzed data obtained from 140 patients who were enrolled in a phase II/III trial comparing low-dose cisplatin with standard-dose cisplatin administered in combination with 5-flurouracil and concomitant radiotherapy. Inclusion criteria were performance status (PS) 0 to 2 and histologically proven thoracic esophageal cancer clinically diagnosed as T4 and/or unresectable lymph node metastasis for which definitive CRT was applicable. Risk factors for esophageal fistula were examined with univariate analysis using Fisher exact test and multivariate analysis using logistic regression models.Esophageal fistula was observed in 31 patients (22%). Of these, 6 patients developed fistula during CRT. Median time interval between the date of CRT initiation and that of fistula diagnosis was 100 days (inter quartile range, 45-171). Esophageal stenosis was the only significant risk factor for esophageal fistula formation both in univariate (P = 0.026) and in multivariate analyses (odds ratio, 2.59; 95% confidence interval, 1.13-5.92, P = 0.025). Other clinicopathological factors, namely treatment arm, age, sex, PS, primary tumor location, T stage, lymph node invasion to adjacent organs, blood cell count, albumin level, and body mass index, were not risk factors fistula formation.Esophageal stenosis was a significant risk factor for esophageal fistula formation in patients treated with CRT for unresectable locally advanced thoracic esophageal squamous cell carcinoma.

    Motivated by the long-recognized value of palpation in detecting breast cancer, we tested the feasibility of a technique for quantitatively evaluating the mechanical properties of breast tissues on the basis of direct MR imaging visualization of acoustic waves. The prototypic elasticity imaging technique consists of a device for generating acoustic shear waves in tissue, an MR imaging-based method for imaging the propagation of these waves, and an algorithm for processing the wave images to generate quantitative images depicting tissue stiffness. After tests with tissue-simulating phantom materials and breast cancer specimens, we used the prototypic breast MR elastography technique to image six healthy women and six patients with known breast cancer. Acoustic shear waves were clearly visualized in phantoms, breast cancer specimens, healthy volunteers, and patients with breast cancer. The elastograms of the tumor specimens showed focal areas of high shear stiffness. MR elastograms of healthy volunteers revealed moderately heterogeneous mechanical properties, with the shear stiffness of fibroglandular tissue measuring slightly higher than that of adipose tissue. The elastograms of patients with breast cancer showed focal areas of high shear stiffness corresponding to the locations of the known tumors. The mean shear stiffness of breast carcinoma was 418% higher than the mean value of surrounding breast tissues. The results confirm the hypothesis that the prototypic breast MR elastographic technique can quantitatively depict the elastic properties of breast tissues in vivo and reveal high shear elasticity in known breast tumors. Further research is needed to evaluate the potential applications of MR elastography, such as detecting breast carcinoma and characterizing suspicious breast lesions.

    Moderate childhood wasting is defined as having a weight-for-height Z-score (WHZ) or = -3. These children are typically given fortified corn/soy blended flour (CSB), but this intervention has shown limited effectiveness. Fortified spreads (FS) can be used as supplementary foods instead; they are energy-dense, lipid-based pastes with added powdered micronutrients. In this randomized clinical effectiveness trial, the recovery rates were compared among children with moderate wasting who received either milk/peanut FS, soy/peanut FS, or CSB. Children received isoenergetic quantities of food, 314 kJ x kg(-1) x d(-1), for up to 8 wk with biweekly follow-up. The primary outcome was recovery, defined as having a WHZ > -2. Time-event analysis was used to compare the recovery rate. A total of 1362 children were enrolled in the study. Children receiving soy/peanut FS had a similar recovery rate to those receiving milk/peanut FS and children in either FS group were more likely to recover than those receiving CSB (80% in both FS groups vs. 72% in the CSB group; P foods to CSB for moderately wasted Malawian children.

  1. Does supplementary reinforcement of stereotypy facilitate extinction?

    Science.gov (United States)

    Dozier, Claudia L; Iwata, Brian A; Wilson, David M; Thomason-Sassi, Jessica L; Roscoe, Eileen M

    2013-01-01

    Results of several studies suggest that delivery of supplemental (social) reinforcement for stereotypy might facilitate its subsequent extinction. We examined this possibility with 9 subjects who engaged in stereotypy by including methodological refinements to ensure that (a) subjects' stereotypy was maintained in the absence of social consequences, (b) supplementary reinforcers were highly preferred and were shown to be reinforcers for some behavior, and (c) subjects were exposed to lengthy reinforcement and extinction conditions. In spite of these modifications, only 4 subjects' stereotypy increased when supplementary reinforcement was delivered contingent on stereotypy, and no subject's stereotypy decreased below initial baseline levels when social reinforcement was subsequently withheld. Decreases in stereotypy occurred with the implementation of noncontingent reinforcement. Thus, delivery of supplementary reinforcers either did not increase stereotypy or did not facilitate extinction of stereotypy maintained by automatic reinforcement. We discuss the practical and conceptual bases of these results with respect to our current understanding of function-based interventions.

    Because cancer of the male breast is rare knowledge about its biology and behavior is essentially due to a compilation of pooled experiences. Hence, a continued report of cases appears to be important. Therefore a retrospective review of patients suffering from male breast cancer was carried out. Twenty-four evaluable cases were analyzed. Eight patients (1 patient with bilateral Stage I carcinoma was included) were in Stage I, 7 in Stage II, 2 in Stage IIIa, 4 in Stage IIIb, and 3 in Stage IV. Of 23 patients who were treated with mastectomy, 22 had modified radical mastectomy and postoperative irradiation to the chest wall as well as to the peripheral lymphatic areas in most cases. One patient underwent radical mastectomy. Another patient had an excision biopsy only, followed by irradiation. One of 24 patients received tamoxifen; another received cyclophosphamide, methotrexate, 5-fluorouracil, prednisone (CMF) regimen in an adjuvant setting. Local recurrence developed in one of 23 (4%) patients treated with mastectomy and radiation therapy to the chest wall and peripheral lymphatics. Four (17%) patients developed distant metastases. The 5-year overall survival (Kaplan-Maier) was 90% for the entire group, 100% for patients in Stage I-III disease, and 60% in Stage IV disease (P = < 0.005). As observed in former reports the stage of disease at initial presentation seems to be a parameter that significantly contributes to survival in male breast cancer patients. To what extent improved local control by adequate local therapy, such as surgery and postoperative radiotherapy, may improve overall survival remains to be discussed. (orig.)

    2003-01-01

    This paper presents an analysis of the possibilities for improving the efficiency of an indi-rectly biomass-fired gas turbine (IBFGT) by supplementary direct gas-firing.

    A common indicator of the measurement of relative poverty is the disposable income of a household. Current research introduces the living standard approach as an alternative concept for describing and measuring relative poverty. This study compares both approaches with regard to subjective health status of the German population, and provides theoretical implications for the utilisation of the income and living standard approach in health research. Analyses are based on the German Socio-Economic Panel (GSOEP) from the year 2011 that includes 12 290 private households and 21106 survey members. Self-rated health was based on a subjective assessment of general health status. Income poverty is based on the equalised disposable income and is applied to a threshold of 60% of the median-based average income. A person will be denoted as deprived (inadequate living standard) if 3 or more out of 11 living standard items are lacking due to financial reasons. To calculate the discriminate power of both poverty indicators, descriptive analyses and stepwise logistic regression models were applied separately for men and women adjusted for age, residence, nationality, educational level, occupational status and marital status. The results of the stepwise regression revealed a stronger poverty-health relationship for the living standard indicator. After adjusting for all control variables and the respective poverty indicator, income poverty was statistically not significantly associated with a poor subjective health status among men (OR Men: 1.33; 95% CI: 1.00-1.77) and women (OR Women: 0.98; 95% CI: 0.78-1.22). In contrast, the association between deprivation and subjective health status was statistically significant for men (OR Men: 2.00; 95% CI: 1.57-2.52) and women (OR Women: 2.11; 95% CI: 1.76-2.64). The results of the present study indicate that the income and standard of living approach measure different dimensions of poverty. In comparison to the income approach, the living

    Abstract Background Since the development of transcriptome analysis systems, many expression evolution studies characterized evolutionary forces acting on gene expression, without explicit discrimination between global expression differences and tissue specific expression differences. However, different types of gene expression alteration should have different effects on an organism, the evolutionary forces that act on them might be different, and different types of genes might show different types of differential expression between species. To confirm this, we studied differentially expressed (DE) genes among closely related groups that have extensive gene expression atlases, and clarified characteristics of different types of DE genes including the identification of regulating loci for differential expression using expression quantitative loci (eQTL) analysis data. Results We detected differentially expressed (DE) genes between rice subspecies in five homologous tissues that were verified using japonica and indica transcriptome atlases in public databases. Using the transcriptome atlases, we classified DE genes into two types, global DE genes and changed-tissues DE genes. Global type DE genes were not expressed in any tissues in the atlas of one subspecies, however changed-tissues type DE genes were expressed in both subspecies with different tissue specificity. For the five tissues in the two japonica-indica combinations, 4.6 ± 0.8 and 5.9 ± 1.5 % of highly expressed genes were global and changed-tissues DE genes, respectively. Changed-tissues DE genes varied in number between tissues, increasing linearly with the abundance of tissue specifically expressed genes in the tissue. Molecular evolution of global DE genes was rapid, unlike that of changed-tissues DE genes. Based on gene ontology, global and changed-tissues DE genes were different, having no common GO terms. Expression differences of most global DE genes were regulated by cis

    This paper examines the hypothesis that a reduction in the distal mural margin during anterior resection for sphincter conservation in rectal cancer excision is safe, provided total mesorectal excision is undertaken with wash-out of the clamped rectum. One hundred ninety-two patients underwent anterior resection and 21 (less than 10%) patients underwent abdomino-perineal excision (APE) by one surgeon (RJH). Anterior resections were classified as "curative" (79%) and "non-curative" (21%); in the "curative" sub-group less than 4% of patients developed local recurrence. The series was retrospectively analyzed for the effect of mural margins on local recurrence with 152 patients undergoing "curative" anterior resections and 40 patients undergoing "non-curative" resections. In the 152 specimens from curative resections, 110 had a resection margin greater than 1 cm and 42 had a resection margin less than 1 cm. Four patients developed local recurrence in the greater than 1 cm margin group (95% confidence interval: 0.8%-7.8%) and no patients developed local recurrence in the less than or equal to 1 cm margin group (95% confidence interval: 0%-5.9%). In each patient with local recurrence a cause for failure was apparent. There was no statistically significant difference in local recurrence rate between the less than or equal to 1 cm margin group and the greater than 1 cm margin group. A reduction in resection margin therefore did not compromise survival after anterior resection. The significance of lateral resection margins is discussed. The role of deep radiotherapy and cytotoxics are considered.(ABSTRACT TRUNCATED AT 250 WORDS)

    Introduction: In the majority of developing countries, the volume of medical insurance services, provided by social insurance organizations is inadequate. Thus, supplementary medical insurance is proposed as a means to address inadequacy of medical insurance. Accordingly, in this article, we attempted to provide the context for expansion of this important branch of insurance through identification of essential factors affecting demand for supplementary medical insurance. Method: In this study, two methods were used to identify essential factors affecting choice of supplementary medical insurance including Classification and Regression Trees (CART) and Bayesian logit. To this end, Excel® software was used to refine data and R® software for estimation. The present study was conducted during 2012, covering all provinces in Iran. Sample size included 18,541 urban households, selected by Statistical Center of Iran using 3-stage cluster sampling approach. In this study, all data required were collected from the Statistical Center of Iran. Results: In 2012, an overall 8.04% of the Iranian population benefited from supplementary medical insurance. Demand for supplementary insurance is a concave function of age of the household head, and peaks in middle-age when savings and income are highest. The present study results showed greater likelihood of demand for supplementary medical insurance in households with better economic status, higher educated heads, female heads, and smaller households with greater expected medical expenses, and household income is the most important factor affecting demand for supplementary medical insurance. Conclusion: Since demand for supplementary medical insurance is hugely influenced by households’ economic status, policy-makers in the health sector should devise measures to improve households’ economic or financial access to supplementary insurance services, by identifying households in the lower economic deciles, and increasing their

    A new supplementary lighting program was designed to increase the egg production of geese under natural light conditions. The objective of this study was to evaluate the effects of the supplementary lighting program on egg production of White Roman geese in an open housing system at the Tropic of Cancer. Forty mature White Roman geese were randomly allocated into two groups (male:female=1:4). The supplementary lighting program with a total daily photoperiod of between 12.0 h and 13.5 h was initiated on 1 November and withdrawn from the experimental group on 30 January. In contrast, the geese in the control group were kept under natural lighting conditions throughout this study. The results showed that the laying peak of the experimental group occurred earlier than normal in the reproductive season and the geese continued laying throughout the breeding season. The geese in the experimental group had 47.6 eggs/goose which was significantly (PTropic of Cancer.

    We consider probabilistic cloning of a state chosen from a mutually nonorthogonal set of pure states, with the help of a party holding supplementary information in the form of pure states. When the number of states is two, we show that the best efficiency of producing m copies is always achieved by a two-step protocol in which the helping party first attempts to produce m-1 copies from the supplementary state, and if it fails, then the original state is used to produce m copies. On the other hand, when the number of states exceeds two, the best efficiency is not always achieved by such a protocol. We give examples in which the best efficiency is not achieved even if we allow any amount of one-way classical communication from the helping party.

    The bilateral supplementary comparison APMP.M.P-S4 on pressure measurements in the range (60 to 350) kPa of gauge pressure in gas media was organized by National Institute of Metrology of Thailand, NIMT, as the pilot laboratory, comparing with Physikalisch-Technische Bundesanstalt of Germany, PTB. The objective of this comparison is to check equivalence of gas pressure standards between NIMT and PTB. The period of measurement covered November to December 2012. NIMT provided a transfer standard, which was a WC-WC piston-cylinder assembly (PCA) with a nominal effective area of 10 cm2 manufactured by Fluke Corporation, DHI. The measurements were performed at pressures (60, 100, 150, 200, 250, 300 and 350) kPa. The NIMT laboratory standard used was a pressure balance with a PCA of 10 cm2 manufactured by DHI and identified by serial number 0693. The PTB laboratory standard used was a pressure balance with a PCA of 10 cm2 manufactured by Desgranges et Huot (DH) and identified by serial number 288. The results of this comparison show that the relative difference of the effective area values obtained by NIMT and PTB is not larger than 4.3 ppm, which corresponds to En = 0.26. Therefore, it confirms that the gas pressure standards maintained by the two institutes, NIMT and PTB, in the pressure range (60 to 350) kPa in gauge mode are equivalent under their uncertainties claimed. The result of this comparison is essential to support the calibration and measurement capabilities (CMC) of NIMT in this pressure range. Main text.

    Full Text Available Abstract Background The National Comprehensive Cancer Network clinical practice guidelines in oncology-gastric cancer guidelines have been widely used to provide appropriate recommendations for the treatment of patients with gastric cancer. The aim of this study was to examine the adherence of surgical oncologists, medical oncologists, and radiation oncologists' to the recommended guidelines. Methods A questionnaire asking the treatment options for gastric cancer cases was sent to 394 Chinese oncology specialists, including surgical oncologists, medical oncologists, and radiation oncologists working in hospitals joined in The Western Cooperative Gastrointestinal Oncology Group of China. The questionnaire involved a series of clinical scenarios regarding the interpretation of surgery, neoadjuvant, adjuvant, and advanced treatment planning of gastric cancer. Results Analysis of 358 respondents (91% showed variations between each specialization and from the recommended guidelines in the management approaches to specific clinical scenarios. The majority of specialists admitted that less than 50% of patients received multidisciplinary evaluation before treatment. The participants gave different responses to questions involving adjuvant, neoadjuvant, and advanced settings, compared to the recommended guidelines. Conclusions These results highlight the heterogeneity of the treatment of gastric cancer. Surgical oncologists, medical oncologists, and radiation oncologists are not adhering to the recommended guidelines.

    Full Text Available CONTEXT: Advances in cancer treatment have led to cure and prolongation of patients′ lives; however associated psychosocial problems, including distress, can detrimentally affect patients′ compliance with treatment and ultimately, their outcome. Symptom distress has been well addressed in many studies; however, psychological distress has only been quantified by using depression or anxiety scales/checklists or quality of life scales containing a distress sub scale/component or by the use of scales that are not psychological distress-specific. AIMS: The present study is an attempt to construct a psychological distress inventory for specific use with cancer patients. SETTINGS AND DESIGN: The standardisation sample consisted of 63 randomly selected patients with head and neck cancer who had undergone/ were undergoing curative treatment at the Regional Cancer Centre, Trivandrum. PATIENTS AND METHODS: The Distress Inventory for Cancer contained 57 positively and negatively toned items. An item analysis was conducted, followed by a factor analysis, thereby identifying the domains influencing distress. RESULTS: The final questionnaire contained 26 items subdivided into four domains viz. the personal, spiritual, physical, and the family domains, with each domain providing a sub score. The reliability coefficient (Cronbach′s alpha of the scale was found to be 0.85. CONCLUSIONS: These are the preliminary results of an ongoing study on global distress and tool development process. Reported here is the first step towards development of such tool.

    Full Text Available Background. This paper aims to present cancer incidence rates at national and regional level of Egypt, based upon results of National Cancer Registry Program (NCRP. Methods. NCRP stratified Egypt into 3 geographical strata: lower, middle, and upper. One governorate represented each region. Abstractors collected data from medical records of cancer centers, national tertiary care institutions, Health Insurance Organization, Government-Subsidized Treatment Program, and death records. Data entry was online. Incidence rates were calculated at a regional and a national level. Future projection up to 2050 was also calculated. Results. Age-standardized incidence rates per 100,000 were 166.6 (both sexes, 175.9 (males, and 157.0 (females. Commonest sites were liver (23.8%, breast (15.4%, and bladder (6.9% (both sexes: liver (33.6% and bladder (10.7% among men, and breast (32.0% and liver (13.5% among women. By 2050, a 3-fold increase in incident cancer relative to 2013 was estimated. Conclusion. These data are the only available cancer rates at national and regional levels of Egypt. The pattern of cancer indicated the increased burden of liver cancer. Breast cancer occupied the second rank. Study of rates of individual sites of cancer might help in giving clues for preventive programs.

  3. Finasteride concentrations and prostate cancer risk: results from the Prostate Cancer Prevention Trial.

    Cindy H Chau

    Full Text Available In the Prostate Cancer Prevention Trial (PCPT, finasteride reduced the risk of prostate cancer by 25%, even though high-grade prostate cancer was more common in the finasteride group. However, it remains to be determined whether finasteride concentrations may affect prostate cancer risk. In this study, we examined the association between serum finasteride concentrations and the risk of prostate cancer in the treatment arm of the PCPT and determined factors involved in modifying drug concentrations.Data for this nested case-control study are from the PCPT. Cases were drawn from men with biopsy-proven prostate cancer and matched controls. Finasteride concentrations were measured using a liquid chromatography-mass spectrometry validated assay. The association of serum finasteride concentrations with prostate cancer risk was determined by logistic regression. We also examine whether polymorphisms in the enzyme target and metabolism genes of finasteride are related to drug concentrations using linear regression.Among men with detectable finasteride concentrations, there was no association between finasteride concentrations and prostate cancer risk, low-grade or high-grade, when finasteride concentration was analyzed as a continuous variable or categorized by cutoff points. Since there was no concentration-dependent effect on prostate cancer, any exposure to finasteride intake may reduce prostate cancer risk. Of the twenty-seven SNPs assessed in the enzyme target and metabolism pathway, five SNPs in two genes, CYP3A4 (rs2242480; rs4646437; rs4986910, and CYP3A5 (rs15524; rs776746 were significantly associated with modifying finasteride concentrations. These results suggest that finasteride exposure may reduce prostate cancer risk and finasteride concentrations are affected by genetic variations in genes responsible for altering its metabolism pathway.ClinicalTrials.gov NCT00288106.

    Improving stability of crop yield in a target production environment is an important breeding objective. It is well known that selection for better stability generally results in lower mean yields and, conversely, that selection for higher mean yields may lead to poorer stability. This paper explores the equivalence between the singular value decomposition used in AMMI analysis and the spectral decomposition used in principal components analysis. This equivalence enables scores of a "supplementary genotype" made up of the highest yield value within each environment to be obtained, and these may serve as the ideal check treatment for selection purposes. These scores are used to (1) display this check in a biplot graph, thereby providing a qualitative comparison with the real genotypes related to their interaction with environments; (2) obtain estimates of the squared distances from the projection of each real genotype to the projection of the "supplementary treatment", thereby allowing conclusions to be made on the yield stability of each real genotype. This procedure was effective in identifying the most stable soybean cultivars in an example shown for illustration.

    The focus of this article is to develop signal and imaging processing methods to derive an accurate estimation of local tissue elasticity using the crawling wave (CrW) sonoelastography method. The task is to reduce noise and to improve the contrast of the elasticity map. The protocol of the CrW approach was first tested on heterogeneous elastic phantoms as a model of prostate cancers. Then, the contrast-to-noise ratio of the estimation was calculated iteratively with various sequences of algorithms to determine the optimal signal processing settings. Finally, the optimized signal processing was applied to ex vivo prostate cancer detection. The comparison of the segmented elasticity map and the histology tumor outline was made by quadrants to evaluate the diagnostic performance of the protocol. Furthermore, the CrW approach was combined with amplitude-sonoelastography to achieve a higher specificity. This study demonstrated the feasibility of the proposed approach for clinical applications. In the application to ex vivo prostate cancer detection, the established approach was tested on 43 excised prostate glands. The combination of the CrW approach and amplitude-sonoelastography achieved an accuracy of over 80% for finding tumors larger than 4 mm in diameter. The elasticity values and contrast found by the CrW approach were in agreement with the previous results derived from mechanical testing. Crawling waves can be applied to detect prostate cancer with accuracy approaching 80% and can quantify the stiffness or shear modulus of both cancerous and noncancerous tissues. The technique therefore shows promise for guiding biopsies to suspect regions that are otherwise difficult to identify.

    Full Text Available Background: Existence or non-existence of adverse selection in insurance market is one of the important cases that have always been considered by insurers. Adverse selection is one of the consequences of asymmetric information. Theory of adverse selection states that high-risk individuals demand the insurance service more than low risk individuals do.Methods: The presence of adverse selection in Irans supplementary health insurance market is tested in this paper. The study group consists of 420 practitioner individuals aged 20 to 59. We estimate two logistic regression models in order to determine the effect of individual's characteristics on decision to purchase health insurance coverage and loss occurrence. Using the correlation between claim occurrence and decision to purchase health insurance, the adverse selection problem in Iranian supplementary health insurance market is examined.Results: Individuals with higher level of education and income level purchase less supplementary health insurance and make fewer claims than others make and there is positive correlation between claim occurrence and decision to purchase supplementary health insurance.Conclusion: Our findings prove the evidence of the presence of adverse selection in Iranian supplementary health insurance market.

    The biplot is a widely and powerful methodology used with multidimensional data sets to describe and display the relationships between observations and variables in an easy way. Compositional data are vectors with positive components, whose sum is constant because they represent a relative contribution of different parts to a whole; due to this property standard biplots cannot be performed with compositional data, instead of a previous transformation of the data is performed. In this paper, we extend the compositional biplot defined by Aitchison and Greenacre (2002), in order to include in the display supplementary elements which are not used in the definition of the compositional biplot. Different types of supplementary elements are considered: supplementary parts of the composition, supplementary continuous variables external to the composition, supplementary categorical variables and supplementary observations. The projection of supplementary parts of the composition is done by means of the equivalence of clr and lr biplots. The other supplementary projections are done by classical methodology. An application example with a real geological data is included.

    MicroRNAs (miRNAs) are small [∼21 nucleotide (nt)] non coding RNAs (ncRNAs) that regulate gene expression posttranscriptionally. About 3.0% of human genes encode for miRNAs, and up to 30.0% of human protein coding genes may be regulated by miRNAs. Currently, more than 2000 unique human mature microRNAs are known. MicroRNAs play a key role in diverse biological processes including development, cell proliferation, differentiation and apoptosis. These processes are commonly dysregulated in cancer, implicating miRNAs in carcinogenesis, where they act as tumor supressors or oncogenes. Several miRNAs are associated with breast cancer. Here we present our initial results of miRNA analyses of breast cancer tissues using quantitative real time-polymerase chain reaction (ReTi-PCR) (qPCR) involving stem-loop reverse transcriptase (RT) primers combined with TaqMan® PCR and miRNA microarray analysis.

    Results of examination of pancreatic diseases, especially pancreatic cancer, conducted by CT during the past 3 years are summarized. The EMI CT Type 5000 or 5005 were used. During the 3 years from September 1976 to August 1979, a total of 1961 patients were examined by CT, and the upper abdomen was examined in 772 of these patients. In 97 patients, positive findings were obtained in the CT image of the pancreas. In 52 of these patients, the findings were confirmed operatively or by autopsy. Though cancer of the pancreas was diagnosed by CT in 30 patients, it was confirmed in 20 by surgical operation and in 1 by autopsy. Of the 9 misdiagnosed cases, 4 were cases of infiltration of the pancreas by carcinoma of the stomach or bile duct, and the other 5 were one case each of lipoma of the abdominal wall, normal pancreas, hyperplasia of Langerhans's islets of the pancreas tail, abscess between the pancreas and the posterior wall of the stomach, and choledocholithiasis. A case diagnosed by CT as cholelithiasis was a carcinoma measuring 5 x 5 x 6 cm located on the head of the pancreas, complicated by choledocholithiasis. The 22 patients with carcinoma of the pancreas were 9 with lesions less than 3.5 x 3.0 x 3.0 cm in size who could be radically operated, 6 who underwent exploratory laparotomy or autopsy, and 7 in whom operation was impossible. False negative and false positive CT results are also discussed.

    We retrospectively analyzed the long-term results of radical surgery and intraoperative radiation therapy (IORT) in patients with stomach cancer. From 1988 to 1994, 51 patients were treated with curative surgery and IORT. Postoperative external beam radiotherapy (EBRT) was administered to 30 patients, while adjuvant chemotherapy was administered to 35 patients. A dose of 15 Gy was irradiated with a 9 MeV electron beam as the IORT and a median dose of EBRT was 43.2 Gy (range, 7.2 to 45 Gy). The follow-up period ranged from 1-254 months, with a median follow-up period of 64 months. The median age of all the patients was 58 years (range, 30 to 71 years). The distribution of pathologic stage (American Joint Committee on Cancer [AJCC] 2002 tumor-note-metastasis [TNM]) was as follows: 13 stage I (25.5%), 10 stage II (19.6%), 25 stage III (49.0%), and 3 stage IV (5.9%). Distant metastases occurred in 11 patients (10 in the peritoneum and 1 in bone), including one patient with concurrent local recurrence (anastomosis site). The 5-year locoregional control, disease free survival and overall survival rates were 94.7%, 66.5%, and 51.7%, respectively. For the multivariate analysis, age, TNM stage, and EBRT were significant prognostic factors for overall survival, and only TNM stage for disease free survival. We could have achieved a high loco-regional control rate in patients with locally advanced stomach cancer by adding IORT to radical surgery. However, the benefit of IORT on survival remains to be elucidated.

    Full Text Available Abstract Background Cachexia is a common problem in patients (pts suffering from upper gastrointestinal cancer. In addition, most of these patients suffer from malabsorption and stenosis of the gastrointestinal tract due to their illness. Various methods of supplementary nutrition (enteral, parenteral are practised. In patients with advanced pancreatic cancer (APC, phase angle, determined by bio-electrical impedance analysis (BIA, seems to be a survival predictor. The positive influence of BIA determinate predictors by additional nutrition is currently under discussion. Methods To examine the impact of additional parenteral nutrition (APN we assessed outpatients suffering from APC and progressive cachexia. The assessment based on the BIA method. Assessment parameters were phase angle, ECM/BCM index (ratio of extracellular mass to body cell mass, and BMI (body mass index. Patients suffering from progressive weight loss in spite of additional enteral nutritional support were eligible for the study. Results Median treatment duration in 32 pts was 18 [8-35] weeks. Response evaluation showed a benefit in 27 pts (84% in at least one parameter. 14 pts (43.7% improved or stabilised in all three parameters. The median ECM/BCM index was 1.7 [1.11-3.14] at start of APN and improved down to 1.5 [1.12-3.36] during therapy. The median BMI increased from 19.7 [14.4-25.9] to 20.5 [15.4-25.0]. The median phase angle improved by 10% from 3.6 [2.3-5.1] to 3.9 [2.2-5.1]. Conclusions We demonstrated the positive impact of APN on the assessed parameters, first of all the phase angle, and we observed at least a temporary benefit or stabilisation of the nutritional status in the majority of the investigated patients. Based on these findings we are currently investigating the impact of APN on survival in a larger patient cohort. Trial registration ClinicalTrials.gov Identifier: NCT00919659

    Pancreatic adenocarcinoma ranks as the fourth most common cause of cancer death in the USA. Patients usually present late with advanced disease, limiting attempted curative surgery to 10% of cases. Overall prognosis is poor with one-year survival rates of less than 10% with palliative chemotherapy and/or radiotherapy. Given these dismal results, a minimally invasive treatment capable of local destruction of tumor tissue with low morbidity may have a place in the treatment of this disease. In this paper we review the preclinical photodynamic therapy (PDT) studies which have shown that it is possible to achieve a zone of necrosis in normal pancreas and implanted tumour tissue. Side effects of treatment and evidence of a potential survival advantage are discussed. We describe the only published clinical study of pancreatic interstitial PDT, which was carried out by our group (Bown et al Gut 2002), in 16 patients with unresectable locally advanced pancreatic adenocarcinoma. All patients had evidence of tumor necrosis on follow-up imaging, with a median survival from diagnosis of 12.5 months. Finally, we outline a phase I dose-escalation study of verteporfin single fibre PDT followed by standard gemcitabine chemotherapy which our group is currently undertaking in patients with locally advanced pancreatic cancer. Randomized controlled studies are also planned.

    Second primary neoplasms (SPNs) are a recognised late effect of treatment for childhood cancer. Thyroid SPNs can develop after exposure to low-dose radiation, due to the radio-sensitivity of the thyroid gland. The British Childhood Cancer Survivor Study (BCCSS) was set up to directly monitor the late effects of treatment, including risk of SPNs, in childhood cancer survivors and includes 17,980 5-year survivors. We carried out a cohort analysis to determine the risk of thyroid SPNs in the BCCSS, and estimated risk using standardised incidence ratios (SIRs), relative risk (RR) using multivariate Poisson regression and cumulative incidence curves. There were 340,202 person years at risk subsequent to a 5-year survival, median follow-up 17.4 years per survivor. We identified 50 thyroid SPNs including 31 (62%) papillary carcinomas, 15 (30%) follicular carcinomas and 4 (8%) other types. 88% of thyroid SPNs developed after exposure to radiotherapy in or around the thyroid gland. SIR overall was 18.0 (95% confidence interval 13.4-23.8). Risk of thyroid cancer was highest after Hodgkin's disease: RR 3.3 (1.1-10.1) and Non Hodgkin's Lymphoma: RR 3.4 (1.1-10.7) relative to leukaemia (RR 1.0) (p Survivors treated with radiotherapy in childhood had a RR of 4.6 (1.4-15.1) relative to survivors not treated with radiotherapy (RR 1.0), p = 0003. In conclusion, the risk of thyroid cancer in childhood cancer survivors is relatively high in this cohort of childhood cancer survivors. These results will be of use in counselling survivors of childhood cancer exposed to radiation in or around the thyroid area.

    Full Text Available CONTEXT: Visceral pain characterizing pancreatic cancer is the most difficult symptom of the disease to control and can significantly impair the quality of life which remains and increase the demand for euthanasia. AIM: To investigate a possible new method based on biophysical principles (scrambler therapy to be used in the effective treatment of drug-resistant oncological pain of the visceral/neuropathic type. SETTING: Eleven terminal cancer patients (3 pancreas, 4 colon, 4 gastric suffering from elevated drug resistant visceral pain. DESIGN: The trial program was related to the first ten treatment sessions. Subsequently, each patient continued to receive treatment until death. MAIN OUTCOME MEASURES: Pain measures were performed using the visual analogue scale before and after each treatment session and accompanied by diary recordings of the duration of analgesia in the hours following each single application. Any variation in pain-killing drug consumption was also recorded. RESULTS: All patients reacted positively to the treatment throughout the whole reference period. Pain intensity showed a significant decrease (P less than 0.001, accompanied by a gradual rise both in the pain threshold and the duration of analgesia. Nine (81.8% of the patients suspended pain-killers within the first 5 applications, while the remaining two (18.2% considerably reduced the dosage taken prior to scrambler therapy. No undesirable side effects were observed. Compliance was found to be optimal. CONCLUSIONS: The preliminary results obtained using scrambler therapy are extremely encouraging, both in terms of enhanced pain control after each treatment session and in view of the possible maintenance of effectiveness over time.

    Most patients with laryngeal carcinoma present tumors in the glottis that can be treated by different treatment modalities. Some authors consider open partial laryngectomy as obsolete, while others still deem this as a viable and cost-efficient option. To compare the oncological and functional results of a series of patients undergoing partial laryngectomy vs. external radiotherapy for the treatment of glottic cancer. Historical cohort study with a series of glottic carcinoma patients undergoing partial laryngectomy or external radiotherapy during a period of ten years. Sixty-two patients with glottic carcinoma were included. Group A comprised those submitted to partial laryngectomy (n=30), and Group B, those who underwent radiotherapy (n=32). They were homogeneous in the comparison of mean age, 56.4 vs. 60.4 years (p=0.12) and distribution in pathological stage (p=0.91). With regard to oncological outcome, there were no differences in distant metastasis rates, or second primary tumor between groups (p=1.0), as well as in disease-free time, laryngeal rescue-free time, and overall five-year survival. Severe complication rates were also similar between groups. Open partial laryngectomy had complication rates and oncological results similar to those of radiotherapy for patients with glottic carcinomas and should still be considered among the main available therapeutic options.

    To study the pattern of cancer incidence and determine the incidence rates in Eastern Libya (for the first time in a decade). A hospital-based registry of cancer patients was formed using records from the primary oncology center in eastern Libya - focusing on those diagnosed in the year 2012. The most common malignancies in men were cancers of the colon (22.3%, n = 90), lung (20.3%, n = 82), prostate (16.1%, n = 65), pancreas (4.2%, n = 17) and liver (4.2%, n = 17). For women, they were found to be cancers of the breast (41.5%, n = 213), colon (16.4%, n = 84), uterus (8%, n = 41), ovary (5.5%, n = 28) and pancreas (3.1%, n = 16). Additionally age-standardized rates (ASR) were determined for Libya. The different cities and towns in eastern Libya were compared for any variation. The city of Beida in particular was found to have a remarkably high incidence of gastric cancer. The different findings were discussed and comparisons were made with past literature as well as the incidence rates for neighbouring countries. The incidence rates given for the eastern region showed differences from previously reported values (i.e., the rate of colon cancer was the highest in North Africa whereas other malignancies occurred less frequently). Potential explanations for the urban-rural difference as well as the difference in incidence rates were put forth. The significance of this study is that it establishes a baseline of cancer incidence which should be the backbone for any future national cancer plan in Libya. Proper surveillance programs need to be in place and healthcare policy should be adjusted to take into account the more prevalent and pressing cancers in society.

We evaluated the efficacy and safety of a partially completed chemoradiation regimen prescribed for locally advanced carcinoma of the cervix. Methods: Medical records of 156 patients with locally advanced cervical cancer stage IIB–IVA who received chemoradiation with cisplatin (40 mg/m2 and 5-fluorouracil (500 mg/m2 from October 2006 to October 2008 were collected. The treatment protocol called for two cycles of chemotherapy. External beam radiation therapy was administered using a 10-MeV electron beam. Local control, disease free survival, overall survival, and toxicities were evaluated. Results: With a median follow-up of 37.5 months, 89 patients (57% completed the planned protocol. Sixty seven patients (43% completed fewer than two cycles. The 3-year local control rate was significantly better in the patient group that completed the prescribed plan (92.1% compared to 80.6%; P = 0.033. No statistical significance was observed between the groups that completed or did not complete the two cycle protocol with regard to disease free survival (80.9% and 73.2%, respectively; P = 0.250, overall survival (84.3% and 79.1%; P = 0.405, and progression survival (3.4% and 3.0%; P = 0.892. Differences in acute hematologic toxicity and subcutaneous toxicity were observed between the two groups. Conclusions: Completion of two cycles of 5-fluorouracil and cisplatin with radiotherapy was effective, safe, and responsible for better local control

    Purpose : The aim of this study is to analyze the survival rate, treatment failure and complication of radiation therapy alone in stage III uterine cervical cancer. Materials and Methods : From January 1980 through December 1985, 227 patients with stage II uterine cervical cancer treated with radiation therapy at Kosin Medical Center were retrospectively studied. Among 227 patients, 72 patients(31.7%) were stage IIIa, and 155 patients(68.3%) were stage IIIb according to FIGO classification. Age distribution was 32-71 years(median: 62 years). Sixty nine patients(95.8%) in stage IIIa and 150 patients(96.8%) in stage IIIb were squamous cell carcinoma. Pelvic lymph node metastasis at initial diagnosis was 8 patients (11.1%) in stage IIIa and 29 patients(18.7%) in stage IIIb. Among 72 patients with stage IIIa, 36 patients(50%) were treated with external radiation therapy alone by conventional technique (180-200 cGy/fr). And 36 patients(50%) were treated with external radiation therapy with intracavitary radiotherapy(ICR) with Cs137 sources, and among 155 patients with stage IIIb, 80 patients(51.6%) were treated with external radiation therapy alone and 75 patients(48.4%) were treated with external radiation therapy with ICR. Total radiation doses of stage IIIa and IIIb were 65-105 Gy(median : 78.5 Gy) and 65-125.5 Gy (median :83.5 Gy). Survival rate was calculated by life-table method. Results : Complete response rates were 58.3% (42 patients) in state IIIa and 56.1%(87 patients) in stage Iiib. Overall 5 year survival rates were 57% in stage IIIa and 40% in stage IIIb. Five year survival rates by radiation technique in stage IIIa and IIIb were 64%, 40% in group treated in combination of external radiation and ICR, and 50%, 40% in the group of external radiation therapy alone(P=NS). Five year survival rates by response of radiation therapy in stage IIIa and IIIb were 90%, 66% in responder group, and 10%, 7% in non-responder group (P<0.01). There were statistically no

    To investigate the treatment outcome and failure patterns after definitive chemoradiation therapy in locally advanced, unresectable esophageal cancer. Materials and Methods: From February 1994 to December 2002, 168 patients with locally advanced unresectable or medically inoperable esophageal cancer were treated by definitive chemoradiation therapy. External beam radiation therapy (EBRT) (42-46 Gy) was delivered to the region encompassing the primary tumor and involved lymph nodes, while the supraclavicular fossa and celiac area were included in the treatment area as a function of disease location. The administered cone-down radiation dose to the gross tumor went up to 54-66 Gy, while the fraction size of the EBRT was 1.8-2.0 Gy/fraction qd or 1.2 Gy/fraction bid. An optional high dose rate (HDR) intraluminal brachytherapy (BT) boost was also administered (Ir-192, 9-12 Gy/3 -4 fx). Two cycles of concurrent FP chemotherapy (5-FU 1,000 mg/m2/day, days 2-6, 30-34, cisplatin 60 mg/m2/day, days 1, 29) were delivered during radiotherapy with the addition of two more cycles. Results: One hundred sixty patients were analyzable for this review [median follow-up time: 10 months (range 1-149 months)]. The number of patients within AJCC stages I, II, III, and IV was 5 (3.1%), 38 (23.8%), 68 (42.5%), and 49 (30.6%), respectively. A HDR intraluminal BT was performed in 26 patients. The 160 patients had a median EBRT radiation dose of 59.4 Gy (range 44.4-66) and a total radiation dose, including BT, of 60 Gy (range 44.4-72), while 144 patients received a dose higher than 40 Gy. Despite the treatment, the disease recurrence rate was 101/160 (63.1%). Of these, the patterns of recurrence were local in 20 patients (12.5%), persistent disease and local progression in 61 (38.1%), distant metastasis in 15 (9.4%), and concomitant local and distant failure in 5 (3.1%). The overall survival rate was 31.8% at 2 years and 14.2% at 5 years (median 11.1 months). Disease-free survival was 29

    Over the past 20 years, cancer research in India has grown in size and impact. Clinicians, scientists, and government and state policy makers in India have championed cancer research, from studies to achieve low-tech, large-scale health outcomes to some of the most advanced areas of fundamental cancer science. In this paper, we frame public policy discussions about cancer with use of an in-depth analysis of research publications from India. Cancer research in India is a complex environment that needs to balance public policy across many competing agendas. We identify major needs across these environments such as those for increased research capacity and training and protected time for clinical researchers; for more support from states and enhanced collaborative funding programmes from government; for development of national infrastructures across a range of domains (ie, clinical trials, tissue banking, registries, etc); and for a streamlined and rational regulatory environment. We also discuss improvements that should be made to translate research into improvements in cancer outcomes and public health. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Skin cancer is the most common form of cancer in the United States and is a recognized public health issue. Diagnosis of skin cancer involves biopsy of the suspicious lesion followed by histopathology. Biopsies, which involve excision of the lesion, are invasive, at times unnecessary, and are costly procedures ( $2.8B/year in the US). An unmet critical need exists to develop a non-invasive and inexpensive screening method that can eliminate the need for unnecessary biopsies. To address this need, our group has reported on the continued development of a noninvasive method that utilizes multimodal spectroscopy towards the goal of a "spectral biopsy" of skin. Our approach combines Raman spectroscopy, fluorescence spectroscopy, and diffuse reflectance spectroscopy to collect comprehensive optical property information from suspicious skin lesions. We previously described an updated spectral biopsy system that allows acquisition of all three forms of spectroscopy through a single fiber optic probe and is composed of off-the-shelf OEM components that are smaller, cheaper, and enable a more clinic-friendly system. We present initial patient data acquired with the spectral biopsy system, the first from an extensive clinical study (n = 250) to characterize its performance in identifying skin cancers (basal cell carcinoma, squamous cell carcinoma, and melanoma). We also present our first attempts at analyzing this initial set of clinical data using statistical-based models, and with models currently being developed to extract biophysical information from the collected spectra, all towards the goal of noninvasive skin cancer diagnosis.

    In most Western nations, the medical oncologist plays a significant role in the administration of systemic therapy for lung cancer. In Japan however, treatment for lung cancer has historically been provided by pulmonologists and thoracic surgeons. A comparison of the management of advanced disease between Japan and other nations has not been described. An online, self-administered, international survey was sent to 3907 active members of the American Society of Clinical Oncology. Eligible participants were degreed physicians who prescribed systemic agents for adult cancer treatment within the past five years. In total, 281 respondents answered the questions regarding management of lung cancer. Thorough analysis demonstrated that pulmonologists play a significant role in Japan and the Netherlands, where the role of oncologic specialists is not well established. Of note, all the respondents from the Netherlands reported that pulmonary medicine primarily manages systemic chemotherapy in stage IV, adjuvant chemotherapy, and targeted therapy. We found there are several nations where non-oncologic specialists play a critical role in the systemic treatment of lung cancer. We expect this practice pattern to continue until the global adoption of the oncologic specialty role. Copyright © 2017 The Japanese Respiratory Society. Published by Elsevier B.V.

    The Zn2+-specific ion channel ZIP7 has been implicated to play an important role in releasing Zn2+ from the ER. External stimulation of breast cancer cells has been proposed to induce phosphorylation of ZIP7 by CK2α, resulting in ZIP7-mediated Zn2+ release from the ER into the cytosol. Here, we examined whether changes in cytosolic and ER Zn2+ concentrations can be detected upon such external stimuli. Two previously developed FRET sensors for Zn2+, eZinCh-2 (K d = 1 nM at pH 7.1) and eCALWY-4 (K d = 0.63 nM at pH 7.1), were expressed in both the cytosol and the ER of wild-type MCF-7 and TamR cells. Treatment of MCF-7 and TamR cells with external Zn2+ and pyrithione, one of the previously used triggers, resulted in an immediate increase in free Zn2+ in both cytosol and ER, suggesting that Zn2+ was directly transferred across the cellular membranes by pyrithione. Cells treated with a second trigger, EGF/ionomycin, showed no changes in intracellular Zn2+ levels, neither in multicolor imaging experiments that allowed simultaneous imaging of cytosolic and ER Zn2+, nor in experiments in which cytosolic and ER Zn2+ were monitored separately. In contrast to previous work using small-molecule fluorescent dyes, these results indicate that EGF–ionomycin treatment does not result in significant changes in cytosolic Zn2+ levels as a result from Zn2+ release from the ER. These results underline the importance of using genetically encoded fluorescent sensors to complement and verify intracellular imaging experiments with synthetic fluorescent Zn2+ dyes. PMID:26739447

    Cancer is a leading cause of death worldwide accounting for 7.4 million deaths. Cancer has become a major public health concern in Algeria. The aim of the present study was to estimate cancer incidence in Mascara Province based on the population-based cancer registry. We analyzed data from the cancer registry of Mascara covering all cancer cases diagnosed by all methods and included in the registry from 1st January 2000 to 31st December 2010. The results are presented as incidence rates of cases by site, sex, age, and crude rate. Age-standardized rates per 100,000 person-years (ASRs) were calculated, using the direct method of standardization to the world population. A total of 1875 cases of invasive cancer were recorded. The mean age of diagnosis for all cancers was 52.66 ± 0.5 in men and 59.18 ± 0.6 in women. The ASR for all cancers in females was 27.8 per 100,000, and that for males was 23.6 per 100,000. The most important finding of the present study was the high incidence of liver cancer among males and females in Mascara. Among females, breast cancer was the most frequently reported followed by Cervix uteri, liver and colon. The most frequent cancer types in males were lung, colon, esophagus and stomach and liver. Cancer incidence in Mascara province was lower than that reported in other national and regional registries. Findings of the present study revealed high incidence of liver cancer in the province, the highest in Algeria, suggesting high prevalence of risk factors. PMID:26417294

    Full Text Available Rett syndrome (RS is a neurological disorder, affecting mainly females, caused by MECP2 mutations usually resulting in severe physical disability. Due to the physical challenges faced by the individual with RS and her family, her rehabilitation program should support her throughout different daily activities, contexts, and surroundings. Rehabilitation interventions to reverse physical impairments include exercise of various types and different physical modalities. Nevertheless, in the vast majority of cases, hands-on therapeutic intervention opportunities are available for the client through a minute part of her waking hours. Hence, a supplementary system is required in order to engulf the child with a comprehensive network of support. Supplementary intervention can support physical impairment by introducing adaptive techniques, environmental modifications, and assistive technologies. The therapy program of an individual with RS should include the use of assistive technology when such devices improve the user's performance. The term “supplementary management” relates to the fact that this intervention may be performed by nonprofessionals with the supervision of a qualified therapist. Such an intervention can further support the therapeutic goals of the child, at a time when direct intervention is not supplied. The present article will review the available literature on the topic of assistive technology, incorporating the clinical knowledge of the author in the field of RS.

    Full Text Available According to art. 34 par. 1 from the UGO no. 34/2001, the court settling the complaint against the offence notice, verifying the legality and substantiality of same, decides on the sanction without distinguishing between the main and the supplementary sanctions. From corroborating these legal provisions with the stipulations under art. 5 from the same normative act, according to which the established sanction must be proportional with the degree of social danger of the committed act, without making differences between the types of sanctions, as well as those of art. 5 and art. 6 according to which the supplementary sanctions are to be applied depending on the nature and seriousness of the fact, it results that the law enforcer has also decided on the right of the court to assess inclusively the proportionality of the sanction in case of applying the supplementary measures, not only in applying main sanctions. And this is so because the proportionality of the committed act and its consequences is one of the requirements demanded by the ECHR jurisprudence in the matter of applying any rights restrictive measures.

    Tubal sterilization is a common form of contraception in the United States and is hypothesized to be associated with a lower risk of breast cancer. However, prior observational studies have reported inconsistent results. We investigated the association between tubal sterilization and breast cancer risk among 77,249 postmenopausal, cancer-free women in the Cancer Prevention Study II (CPS-II) Nutrition Cohort, enrolled in 21 states in the United States during 1992-1993. During 15 years of follow-up through June 30, 2007, 4,084 invasive breast cancer cases were diagnosed. Multivariable Cox proportional hazard regression was used to estimate hazard ratios and 95% confidence intervals. A meta-analysis including the CPS-II Nutrition Cohort results with other published results from 4 case-control studies and 3 prospective studies was conducted to provide a summary estimate for the association between tubal sterilization and breast cancer risk. In the CPS-II Nutrition Cohort, tubal sterilization was not associated with breast cancer incidence (multivariable-adjusted hazard ratio = 1.08, 95% confidence interval: 0.97, 1.20). Associations stratified by year of tubal sterilization, age, and time since surgery were also null. The meta-analysis also found no association between tubal sterilization and breast cancer risk (odds ratio = 0.97, 95% confidence interval: 0.84, 1.09). Tubal sterilization does not appear to be associated with breast cancer risk.

    We evaluated the effectiveness and safety of ipsilateral radiotherapy for the patient with well lateralized tonsil cancer: not cross midline and <1 cm of tumor invasion into the soft palate or base of tongue. From 2003 to 2011, twenty patients with well lateralized tonsil cancer underwent ipsilateral radiotherapy. Nineteen patients had T1-T2 tumors, and one patient had T3 tumor; twelve patients had N0-N2a disease and eight patients had N2b disease. Primary surgery followed by radiotherapy was performed in fourteen patients: four of these patients received chemotherapy. Four patients underwent induction chemotherapy followed by concurrent chemoradiotherapy (CCRT). The remaining two patients received induction chemotherapy followed by radiotherapy and definitive CCRT, respectively. No patient underwent radiotherapy alone. We analyzed the pattern of failure and complications. The median follow-up time was 64 months (range, 11 to 106 months) for surviving patients. One patient had local failure at tumor bed. There was no regional failure in contralateral neck, even in N2b disease. At five-year, local progression-free survival, distant metastasis-free survival, and progression-free survival rates were 95%, 100%, and 95%, respectively. One patient with treatment failure died, and the five-year overall survival rate was 95%. Radiation Therapy Oncology Group grade 2 xerostomia was found in one patient at least 6 months after the completion of radiotherapy. Ipsilateral radiotherapy is a reasonable treatment option for well lateralized tonsil cancer. Low rate of chronic xerostomia can be expected by sparing contralateral major salivary glands.

    Full Text Available Supplementary contents along motorways are rather important facilities for a safe and secure functioning of a substantial part of the road transport system. In the paper, it has been stressed that our practice has not dealt with this problem satisfactorily throughout the motorways design process and especially in the realization phase. Therefore, the solving of this major issue ought to be approached systematically and planning oriented so as to achieve an optimal effect of supplementary contents in the motorways’ exploitation. The role of these facilities is multifold. Some relate to a safer road functioning and some enable a more comfortable and secure traveling. To make them work as a system it is indispensable to set up location selection criteria and rules for the complementary facilities Respecting the adequate rhythm and function dominance is exceptionally important as well as establishing the traffic safety and applying high ecological standards.

    To describe preliminary findings from the colorectal cancer screening programme in Aragon (Spain) to evaluate its implementation. We have collected data from the first year of the program (2014) based on faecal occult blood immunochemical (FOBTi) test in patients 60-69 years old. We report "indicators" defined by the "Red Nacional de Cribado". Invited population after exclusions: 12,518. Program participation rate: 45.28% (95%CI: 44.41-46.15). Inadequate tests: 0.21% (95%CI: 0.12-0.37); positive FOBTi test 10.75% (95%CI: 9.97-11.58) and colonoscopy acceptance 95.07% (95%CI: 93.04-96.52). Colonoscopy was appropriate and complete in 97.58% (95%CI: 95.98-98.55) of cases. The high- and low-risk adenoma detection rates were 14.7‰ (95%CI: 11.9-18.2) and 5.55‰ (95%CI: 3.9-7.8) respectively. The positive predictive value for any adenoma was 58.55% (95%CI: 54.49-62.49) and for invasive cancer was 5.36% (95%CI: 3.8-7.51). The indicator analysis of the ongoing programme suggests the programme is being implemented correctly in our community. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U.

    2014-01-01

    Background The etiology of male breast cancer is poorly understood, partly because of its relative rarity. Although genetic factors are involved, less is known regarding the role of anthropometric and hormonally related risk factors. Methods In the Male Breast Cancer Pooling Project, a consortium of 11 case–control and 10 cohort investigations involving 2405 case patients (n = 1190 from case–control and n = 1215 from cohort studies) and 52013 control subjects, individual participant data were harmonized and pooled. Unconditional logistic regression generated study design–specific (case–control/cohort) odds ratios (ORs) and 95% confidence intervals (CIs), with exposure estimates combined using fixed effects meta-analysis. All statistical tests were two-sided. Results Risk was statistically significantly associated with weight (highest/lowest tertile: OR = 1.36; 95% CI = 1.18 to 1.57), height (OR = 1.18; 95% CI = 1.01 to 1.38), and body mass index (BMI; OR = 1.30; 95% CI = 1.12 to 1.51), with evidence that recent rather than distant BMI was the strongest predictor. Klinefelter syndrome (OR = 24.7; 95% CI = 8.94 to 68.4) and gynecomastia (OR = 9.78; 95% CI = 7.52 to 12.7) were also statistically significantly associated with risk, relations that were independent of BMI. Diabetes also emerged as an independent risk factor (OR = 1.19; 95% CI = 1.04 to 1.37). There were also suggestive relations with cryptorchidism (OR = 2.18; 95% CI = 0.96 to 4.94) and orchitis (OR = 1.43; 95% CI = 1.02 to 1.99). Although age at onset of puberty and histories of infertility were unrelated to risk, never having had children was statistically significantly related (OR = 1.29; 95% CI = 1.01 to 1.66). Among individuals diagnosed at older ages, a history of fractures was statistically significantly related (OR = 1.41; 95% CI = 1.07 to 1.86). Conclusions Consistent findings across case–control and cohort investigations, complemented by pooled analyses, indicated important roles for

    Full Text Available The study seeks to investigate the status of supplementary tuition in the teaching and learning of mathematics and mathematical literacy. The study followed a descriptive survey design involving the use of learner and teacher questionnaires. A convenient sample of mathematics and mathematical literacy teachers together with a stratified sample of their Grade 11 learners were drawn from a purposive sample of highperforming high schools in the East London district of the Eastern Cape, South Africa. The results show that supplementary tuition is popular, especially among girls, and it is in three forms (i.e. private tuition, vacation school and problem-solving classes: Problemsolving classes dominated by working on past/model examination papers is the most preferred; in some instances supplementary tuition is offered for a fee; it is not only confined to poor performing learners; and participation in supplementary tuition is influenced by a variety of factors.

    Cancer prevention is a broad field that crosses many disciplines; therefore, educational efforts to enhance cancer prevention research focused on interdisciplinary approaches to the field are greatly needed. In order to hasten progress in cancer prevention research, the Cancer Prevention Internship Program (CPIP) at Purdue University was designed to develop and test an interdisciplinary curriculum for undergraduate and graduate students. The hypothesis was that course curriculum specific to introducing interdisciplinary concepts in cancer prevention would increase student interest in and ability to pursue advanced educational opportunities (e.g., graduate school, medical school). Preliminary results from the evaluation of the first year which included 10 undergraduate and 5 graduate students suggested that participation in CPIP is a positive professional development experience, leading to a significant increase in understanding of interdisciplinary research in cancer prevention. In its first year, the CPIP project has created a successful model for interdisciplinary education in cancer prevention research. PMID:21533583

  8. Synchronous Onset of Breast and Pancreatic Cancers: Results of Germline and Somatic Genetic Analysis

    Directory of Open Access Journals (Sweden)

    Michael Castro

    2016-07-01

    Full Text Available Background: Synchronous cancers have occasionally been detected at initial diagnosis among patients with breast and ovarian cancer. However, simultaneous coexistence and diagnosis of breast and pancreas cancer has not previously been reported. Case Report: Paternal transmission of a germline BRCA2 mutation to a patient who was diagnosed at age 40 with locally advanced breast and pancreas cancer is presented. Somatic genomic analysis of both cancers with next-generation DNA sequencing confirmed the germline result and reported a variety of variants of unknown significance alterations, of which two were present in both the breast and pancreas cancers. Discussion: The possibility that genomic alterations could have been responsible for modulating the phenotypic or clinical expression of this rare presentation is considered. The authors call attention to the practice of privatizing the clinicogenetic information gained from genetic testing and call for health policy that will facilitate sharing in order to advance the outcomes of patients diagnosed with hereditary cancers.

    This study was conducted to determine the use of screening for stomach, liver, colorectal, breast, and cervical cancers, which are included in the Korean National Cancer Screening Programme. In 2011 the National Cancer Centre in Korea conducted a nationwide, population-based, cross-sectional interview survey using multi-stage random sampling. Participants included 4,100 cancer-free men 40 years and over of age and women over 30 years of age. The lifetime screening rates for stomach, liver, colorectal, breast, and cervical cancers were 76.2%, 54.3%, 56.1%, 79.0%, and, 74.8%, respectively. The rates of recommended screening for stomach, liver, colorectal, breast, and cervical cancers were 64.6%, 22.9%, 35.3%, 60.4%, and 62.4%, respectively. More than 70% of all screening was attributed to organised cancer screening programmes. The main reason given for non attendance was 'no symptoms'. A greater effort is needed to increase screening rates, especially for liver and colorectal cancers.

    Full Text Available Abstract Background Vitamin D enhances host protective immune responses to Mycobacterium tuberculosis by suppressing Interferon-gamma (IFN-g and reducing disease associated inflammation in the host. The objectives of this study were to determine whether vitamin D supplementation to patients with tuberculosis (TB could influence recovery. Methods Two hundred and fifty nine patients with pulmonary TB were randomized to receive either 600,000 IU of Intramuscular vitamin D3 or placebo for 2 doses. Assessments were performed at 4, 8 and 12 weeks. Early secreted and T cell activated 6 kDa (ESAT6 and Mycobacterium tuberculosis sonicate (MTBs antigen induced whole blood stimulated IFN-g responses were measured at 0 and 12 weeks. Statistical comparisons between outcome variables at 0 and 12 weeks were performed using Student’s t-test and Chi2 tests. Results After 12 weeks, the vitamin D supplemented arm demonstrated significantly greater mean weight gain (kg + 3.75, (3.16 – 4.34 versus + 2.61 (95% CI 1.99 – 3.23 p 0.009 and lesser residual disease by chest radiograph; number of zones involved 1.35 v/s 1.82 p 0.004 (95% CI 0.15, 0.79 and 50% or greater reduction in cavity size 106 (89.8% v/s 111 (94.8%, p 0.035. Vitamin D supplementation led to significant increase in MTBs-induced IFN-g secretion in patients with baseline ‘Deficient’ 25-hydroxyvitamin D serum levels (p 0.021. Conclusions Supplementation with high doses of vitamin D accelerated clinical, radiographic improvement in all TB patients and increased host immune activation in patients with baseline ‘Deficient’ serum vitamin D levels. These results suggest a therapeutic role for vitamin D in the treatment of TB. Trial registration ClinicalTrials.gov; No. NCT01130311; URL: clinicaltrials.gov

    Moderate and severe acute malnutrition affects 13% of children food (RUSF) and the more conventional ration of corn-soya blend (CSB) in Ethiopia. A total of 1125 children aged 6-60 mo with moderate acute malnutrition received 16 wk of CSB or RUSF. Children were randomly assigned to receive one or the other food. The daily rations were purposely based on the conventional treatment rations distributed at the time of the study in Ethiopia: 300 g CSB and 32 g vegetable oil in the control group (1413 kcal) and 92 g RUSF in the intervention group (500 kcal). The higher ration size of CSB was provided because of expected food sharing. The HR for children in the CSB group was 0.85 (95% CI: 0.73, 0.99), which indicated that they had 15% lower recovery (P = 0.039). Recovery rates of children at the end of the 16-wk treatment period trended higher in the RUSF group (73%) than in the CSB group (67%) (P = 0.056). In comparison with CSB, the treatment of moderate acute malnutrition with RUSF resulted in higher recovery rates in children, despite the large ration size and higher energy content of the conventional CSB ration.

    We investigated the cancer screening rates for five types of cancer (stomach, liver, colorectal, breast, and cervix uteri) using data from the Korean National Cancer Screening Survey (KNCSS), which is a nationwide, annual cross-sectional survey. The eligible study population included cancer-free men 40 years of age and older and women 30 years of age and older. The lifetime screening rate and screening rate with recommendation were calculated. The lifetime screening rates for gastric, liver, colorectal, breast, and cervical cancers were 77.9%, 69.9%, 65.8%, 82.9%, and 77.1%, respectively. The screening rates with recommendation were 70.9%, 21.5%, 44.7%, 70.9%, and 67.9%, respectively. The most common reason for all types of cancer was "no symptoms, " followed by "lack of time" and "fear of the examination procedure. " Efforts to facilitate participation in liver and colorectal cancer screening among Korean men and women are needed.

    Background ABO blood group has been associated with risk of cancers of the pancreas, stomach, ovary, kidney and skin, but has not been evaluated in relation to risk of aggressive prostate cancer. Methods We used three single nucleotide polymorphisms (SNPs) (rs8176746, rs505922, and rs8176704) to determine ABO genotype in 2,774 aggressive prostate cancer cases and 4,443 controls from the Breast and Prostate Cancer Cohort Consortium (BPC3). Unconditional logistic regression was used to calculate age and study adjusted odds ratios and 95% confidence intervals for the association between blood type, genotype and risk of aggressive prostate cancer (Gleason score ≥8 or locally advanced/metastatic disease (stage T3/T4/N1/M1). Results We found no association between ABO blood type and risk of aggressive prostate cancer (Type A: OR=0.97, 95% CI=0.87-1.08; Type B: OR=0.92, 95% CI=0.77-1.09; Type AB: OR=1.25, 95% CI=0.98-1.59, compared to Type O, respectively). Similarly, there was no association between ‘dose’ of A or B alleles and aggressive prostate cancer risk. Conclusions ABO blood type was not associated with risk of aggressive prostate cancer.

    Full Text Available Breast cancer patients with bone metastasis who had admitted to Dicle University Department of Radiation Oncology for palliative radiation therapy between September 2001 and December 2003 were evaluated. There were 31 patients (26 female, 5 male. Median age was 43 years (range 23-79. Histopathological subtypes were infiltrating ductal carcinoma (88%, tubulolobuler carcinoma (6% and inflammatory carcinoma (6%. Loci of bone metastasis were vertebra only in twelve patients (39%, non-vertebral bones only in 8 patients (26% and both vertebral and nonvertebral bones in 11 patients (35%. Two patients had refused radiotherapy. Radiation doses were 3000 cGy with 10 fractions in 15 patients, 2000 cGy with 5 fractions in 6 patients and 800 cGy single fraction in eight patients. Complete palliation of pain was achieved in 18 patients (62% and partial palliation was achieved in 11 patients (38%. Treatment related toxicity was grade I-II dermatitis. In conclusion; same respons rates in terms of palliation can be achieved in the three radiotherapy schedules.

    We consider the different spin supplementary conditions (SSC) for a spinning compact binary with the leading-order spin-orbit (SO) interaction. The Lagrangian of the binary system can be constructed but it is acceleration-dependent in two cases of SSC. We rewrite the generalized Hamiltonian formalism proposed by Ostrogradsky and compute the conservative quantities and the dissipative part of relative motion during the gravitational radiation of each SSCs. We give the orbital elements and observed quantities of the SO dynamics, for instance the energy and the orbital angular momentum losses and waveforms and discuss their SSC dependence.

    BACKGROUND Hyperinsulinemia and obesity-related metabolic disturbances are common and have been associated with increased cancer risk and poor prognosis. METHODS Data are from a case-control study within the Prostate Cancer Prevention Trial (PCPT), a randomized, placebo-controlled trial testing finasteride vs. placebo for primary prevention of prostate cancer. Cases (n=1803) and controls (n= 1797) were matched on age, PCPT treatment arm, and family history of prostate cancer; controls included all eligible non-whites. Outcomes were biopsy-determined. Baseline bloods were assayed for serum C-peptide (marker of insulin secretion) and leptin (an adipokine) using ELISA. Logistic regression calculated odds ratios for total prostate cancer and polytomous logistic regression calculated odds ratios for low-grade (Gleason prostate cancer (Gleason ≥ 7) (multivariate-adjusted OR= 1.88, 95%CI 1.19-2.97, p trend = 0.004). When C-peptide was modeled as a continuous variable, every unit increase in [log(C-peptide)], resulted in a 39% increased risk of high-grade disease (p=0.01). In contrast, there was no significant relationship between C-peptide and high-grade prostate cancer among men receiving finasteride. Leptin was not independently associated with high-grade prostate cancer. CONCLUSIONS These results support findings from other observational studies that high serum C-peptide and insulin-resistance, but not leptin, are associated with increased risk of high-grade prostate cancer. Our novel finding is that the C-peptide-associated risk was attenuated by use of finasteride. PMID:20179296

    Screening using fecal occult blood testing (FOBt) reduces colorectal cancer mortality, but the test has low sensitivity. A "missed" cancer may cause psychologic harms in the screened population that partially counteract the benefits of early detection. Three hundred and eleven people diagnosed with colorectal cancer (i) after a negative FOBt result (interval cancer), (ii) a positive result (screen-detected cancer), or (iii) in regions where screening was not offered, completed questions on quality of life (FACT-C), depression (CES-D), perceived diagnostic delay, and trust in the results of FOBt screening. Fifteen withheld consent to data matching with medical records, leaving a sample size of 296. Controlling for demographic and clinical variables, patients with an interval cancer reported poorer quality of life (difference in means = 6.16, P = 0.03) and more diagnostic delay (OR, 0.37; P = 0.02) than patients with screen-detected disease, with no differences in depression. No differences were observed between the interval cancer group and the group not offered screening on these measures. Patients with an interval cancer reported the lowest levels of trust in FOBt. An interval cancer has adverse effects on trust in FOBt, but does not result in worse psychologic outcomes compared with people diagnosed in areas with no screening program. People with an interval cancer report poorer quality of life than people with screen-detected disease. Improvements in test sensitivity could improve quality of life among people who complete an FOB test over and above any benefits already conferred by earlier detection. ©2015 American Association for Cancer Research.

    The results of primary radiotherapy in anal carcinoma are reported in a retrospective study. Fourteen patients have been treated by primary radiotherapy between 1970 and 1982. The three-year survival rate is 11/14 (corrected: 11/12). Among eleven patients followed up, ten have a normal anal function. The importance of radio-oncology as a therapy of choice in conservative, function-preserving treatment of the anal carcinoma is discussed regarding the retrospective results as well as possible combinations of radiotherapy and chemotherapy.

    Full Text Available The results of clinical study for efficacy of photodynamic therapy (PDT with radachlorine in patients with pre-cancer and cancer of cervix are represented. The study enrolled 30 patients including 4 patients with cervical erosion, 5 patients with cervical intraepithelial neoplasia II, 13 patients with cervical intraepithelial neoplasia III, 4 patients with carcinoma in situ and 4 patients with cervical cancer stage Ia. Radachlorine was administrated as single 30 minute intravenous injection at dose of 1,0 mg/kg of body weight 3 h before irradiation (wavelength of 662 nm, light dose of 300–350 J/cm2. The results of treatment in 26 (86,7% patients was assessed as complete tumor regression and in 4 (13,3% patients — as partial regression. In cervical erosion, intraepithelial neoplasia II and carcinoma in situ groups total regression was in all cases. In the cervical intraepithelial neoplasia III group total regression after first course of PDT was achieved in 77% of patients, in cervical cancer stage Ia group – in 75% of patients. From 3 to 6 months after first course of treatment all patients with partial tumor regression underwent the second course of PDT with complete regression. There were no side-effects due to radachorine or PDT in the course of treatment and during follow-up. Thus, PDT with Russian photosensitizer radachlorine showed high efficiency for treatment of pre-cancer and cancer of cervix.

    Full Text Available Since 2003 new healthcare reforms have been implemented in Turkey. Although, the healthcare system has gone through modifications for the past several years; there is insufficient research to demonstrate the effects of these changes. This paper aims to address the issues in the supplementary payment systems, which are one of the recent changes of the healthcare system in the country. This study is mainly based on a review of the relevant professional literature, a research and interpretation of supplementary payment in the public hospitals. This is a research as well as an assessment work done in secondary and tertiary care hospitals. Performance based supplementary payment system in public hospitals aims to provide bonuses to health care employees like physicians, nurses, etc. The bonus is given to professionals, who produce the qualified health services based on records by the evaluation of the whole institution. Financing of supplementary payment system in Turkey is mainly based on social security premiums. Consequently, balance of income and expenditures at hospitals is needed to be followed sensitively. According to this study, physicians' productivity has increased but number of patients per physician has decreased. Also, the amount of performance paid to the physician for their specialty has decreased. Physicians like cardiologists can benefit more from the pay for performance system as their work contributions are paid more compared to internist work. Also secondary care hospital staffs were better paid compared to tertiary care hospitals because more critical cases are sent to tertiary care and treatment of such cases are of high cost. The reforms resulted satisfactory and very successful improvement in healthcare performance. The main health indicators are now better than at the beginning of the transition period. The sustainability of the reform processes will cause further improvement in the near future. The number of treatments per

    Full Text Available Abstract Background Liver cancer is one of most commonly diagnosed cancers among Koreans. Chronic hepatitis B virus (HBV infection is a major risk factor for liver cancer. HBV infection can be prevented by effective screening and vaccination programs. The purpose of this study is to examine the status of HBV infection and the predictors associated with HBV vaccination. Methods The study population was derived from the 2005 Korea National Cancer Screening Survey (KNCSS. The KNCSS is an annual cross-sectional survey that uses a nationally-representative random sampling to investigate cancer screening rates. A total of 1,786 Koreans over 40 years of age participated in this study. Results Of all the participants, 5.9% reported HBV positive (HBsAg+, HBsAb-, 41.8% were HBV negative but protected (HBsAg-, HBsAb+, and 52.3% were unprotected (HBsAg-, HBsAb-. Among unprotected individuals (n = 934, 23.1% reported to have received the vaccination. About half of those who had vaccinations completed the 3-shot vaccine series. In multiple analyses, education, having private cancer insurance, alcohol use, having regular check-up, and doing regular exercise were associated with completed HBV vaccination. Conclusion This study result suggests that we need a liver cancer education program to increase HBV awareness and to increase the liver cancer prevention message among low educated populations.

    As of April 2015, participants in the Danish Lung Cancer Screening Trial had been followed for at least 5 years since their last screening. Mortality, causes of death, and lung cancer findings are reported to explore the effect of computed tomography (CT) screening. A total of 4,104 participants aged 50-70 years at the time of inclusion and with a minimum 20 pack-years of smoking were randomized to have five annual low-dose CT scans (study group) or no screening (control group). Follow-up information regarding date and cause of death, lung cancer diagnosis, cancer stage, and histology was obtained from national registries. No differences between the two groups in lung cancer mortality (hazard ratio, 1.03; 95% confidence interval, 0.66-1.6; P = 0.888) or all-cause mortality (hazard ratio, 1.02; 95% confidence interval, 0.82-1.27; P = 0.867) were observed. More cancers were found in the screening group than in the no-screening group (100 vs. 53, respectively; P risk of death due to lung cancer, with nonsignificantly fewer deaths in the screening group. No statistically significant effects of CT screening on lung cancer mortality were found, but the results of post hoc high-risk subgroup analyses showed nonsignificant trends that seem to be in good agreement with the results of the National Lung Screening Trial. Clinical trial registered with www.clinicaltrials.gov (NCT00496977).

    2014-06-01

    The use of real-time quantitative polymerase chain reaction (qPCR) in cancer research has become ubiquitous. The relative simplicity of qPCR experiments, which deliver fast and cost-effective results, means that each year an increasing number of papers utilizing this technique are being published. But how reliable are the published results? Since the validity of gene expression data is greatly dependent on appropriate normalisation to compensate for sample-to-sample and run-to-run variation, we have evaluated the adequacy of normalisation procedures in qPCR-based experiments. Consequently, we assessed all colorectal cancer publications that made use of qPCR from 2006 until August 2013 for the number of reference genes used and whether they had been validated. Using even these minimal evaluation criteria, the validity of only three percent (6/179) of the publications can be adequately assessed. We describe common errors, and conclude that the current state of reporting on qPCR in colorectal cancer research is disquieting. Extrapolated to the study of cancer in general, it is clear that the majority of studies using qPCR cannot be reliably assessed and that at best, the results of these studies may or may not be valid and at worst, pervasive incorrect normalisation is resulting in the wholesale publication of incorrect conclusions. This survey demonstrates that the existence of guidelines, such as MIQE, is necessary but not sufficient to address this problem and suggests that the scientific community should examine its responsibility and be aware of the implications of these findings for current and future research.

    Although some patients have successful peripheral nerve regeneration, a poor recovery of hand function often occurs after peripheral nerve injury. It is believed that the capability of brain plasticity is crucial for the recovery of hand function. The supplementary motor area may play a key role in brain remodeling after peripheral nerve injury. In this study, we explored the activation mode of the supplementary motor area during a motor imagery task. We investigated the plasticity of the central nervous system after brachial plexus injury, using the motor imagery task. Results from functional magnetic resonance imaging showed that after brachial plexus injury, the motor imagery task for the affected limbs of the patients triggered no obvious activation of bilateral supplementary motor areas. This result indicates that it is dififcult to excite the supplementary motor areas of brachial plexus injury patients during a motor imagery task, thereby impacting brain remodeling. Deactivation of the supplementary motor area is likely to be a serious problem for brachial plexus injury patients in terms of preparing, initiating and executing certain movements, which may be partly responsible for the unsatisfactory clinical recovery of hand function.

    Purpose Observational studies have demonstrated increased colon cancer recurrence in states of relative hyperinsulinemia, including sedentary lifestyle, obesity, and increased dietary glycemic load. Greater coffee consumption has been associated with decreased risk of type 2 diabetes and increased insulin sensitivity. The effect of coffee on colon cancer recurrence and survival is unknown. Patients and Methods During and 6 months after adjuvant chemotherapy, 953 patients with stage III colon cancer prospectively reported dietary intake of caffeinated coffee, decaffeinated coffee, and nonherbal tea, as well as 128 other items. We examined the influence of coffee, nonherbal tea, and caffeine on cancer recurrence and mortality using Cox proportional hazards regression. Results Patients consuming 4 cups/d or more of total coffee experienced an adjusted hazard ratio (HR) for colon cancer recurrence or mortality of 0.58 (95% CI, 0.34 to 0.99), compared with never drinkers (Ptrend = .002). Patients consuming 4 cups/d or more of caffeinated coffee experienced significantly reduced cancer recurrence or mortality risk compared with abstainers (HR, 0.48; 95% CI, 0.25 to 0.91; Ptrend = .002), and increasing caffeine intake also conferred a significant reduction in cancer recurrence or mortality (HR, 0.66 across extreme quintiles; 95% CI, 0.47 to 0.93; Ptrend = .006). Nonherbal tea and decaffeinated coffee were not associated with patient outcome. The association of total coffee intake with improved outcomes seemed consistent across other predictors of cancer recurrence and mortality. Conclusion Higher coffee intake may be associated with significantly reduced cancer recurrence and death in patients with stage III colon cancer. PMID:26282659

    While cervical cancer screening is useful for detecting and then treating the disease at an early stage, most women with screen-positive results are free from cervical cancer but nevertheless subject to the unnecessary worry entailed in receiving such results. The purpose of this study was to examine whether receiving a screen-positive result was actually related to psychological distress among Japanese women who underwent cervical cancer screening. We conducted a questionnaire survey at health facilities in a semiurban city of Ibaraki prefecture, involving 1744 women who underwent cervical cancer screening and 72 who received screen-positive results and then underwent further testing. We used the K6 scale to assess their psychological distress (K6 score ≥5) and performed multiple logistic regression analyses to estimate the relative effect of receiving screen-positive results on psychological distress. Psychological distress was more prevalent among women with screen-positive results (OR 2.22; 95 % CI 1.32-3.74), while it was also related to history of mental health consultation (OR 2.26; 95 % CI 1.69-3.01) and marital status (OR 1.32; 95 % CI 1.02-1.70). Receiving a positive cervical cancer screening result was associated with psychological distress. To alleviate this psychological impact, the current form of communicating the screening results should be reconsidered.

    Full Text Available Objective: The disclosure of the diagnosis of cancer is a distressing and complex issue. Families and doctors still do not tell patients when they have cancer in the belief that the patient does not want to know and telling him would lead to fear and depression. The aim of this survey was to evaluate the information needs of Indian cancer patients. Materials and Methods: A cross-sectional survey of 300 patients′ views was conducted with the help of an adaptation of Cassileth′s Information Needs questionnaire. Results: A majority of cancer patients exhibited a strong need for information about illness and treatment. Ninety-four percent wanted to know if their illness was cancer. Most patients also wanted to know the chance of cure (92%. Age, education, and type of treatment significantly affect information preferences. Gender did not have an effect on information needs. Conclusion: This study showed that most of the patients wanted to know about their illness, treatment, side-effects, and chances of cure.

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

  3. Improving supplementary feeding in species conservation

    2015-01-01

    Supplementary feeding is often a knee-jerk reaction to population declines, and its application is not critically evaluated, leading to polarized views among managers on its usefulness. Here, we advocate a more strategic approach to supplementary feeding so that the choice to use it is clearly justified over, or in combination with, other management actions and the predicted consequences are then critically assessed following implementation. We propose combining methods from a set of specialist disciplines that will allow critical evaluation of the need, benefit, and risks of food supplementation. Through the use of nutritional ecology, population ecology, and structured decision making, conservation managers can make better choices about what and how to feed by estimating consequences on population recovery across a range of possible actions. This structured approach also informs targeted monitoring and more clearly allows supplementary feeding to be integrated in recovery plans and reduces the risk of inefficient decisions. In New Zealand, managers of the endangered Hihi (Notiomystis cincta) often rely on supplementary feeding to support reintroduced populations. On Kapiti island the reintroduced Hihi population has responded well to food supplementation, but the logistics of providing an increasing demand recently outstretched management capacity. To decide whether and how the feeding regime should be revised, managers used a structured decision making approach informed by population responses to alternative feeding regimes. The decision was made to reduce the spatial distribution of feeders and invest saved time in increasing volume of food delivered into a smaller core area. The approach used allowed a transparent and defendable management decision in regard to supplementary feeding, reflecting the multiple objectives of managers and their priorities.

    2005-01-01

    Full Text Available Context: In 2000, the number of new cases of prostate cancer was estimated at 5 13 000 worldwide [Eur J Cancer 2001; 37 (Suppl 8: S4]. In next 15 years, prostate cancer is predicted to be the most common cancer in men [Eur J Cancer 2001; 37 (Suppl 8: S4]. Radical prostatectomy is one of the most common surgical treatments for clinically localized prostate cancer. In spite of its excellent oncological results, due to the fear of pain, risk for side effects, and inconvenience (Semin Urol Oncol 2002; 20: 55, many patients seek alternative treatments for their prostate cancer. At Vattikuti Urology institute, we have developed a minimally invasive technique for treating prostate cancer, which achieves oncological results of surgical treatment without causing significant pain, large surgical incision, and side effects (BJU Int, 2003; 92: 205. This technique involves a da Vinci™ (Intuitive Surgical ®, Sunnyvale, CA surgical robot with 3-D stereoscopic visualization and ergonomic multijointed instruments. Presented herein are our results after treating 750 patients. Methods: We prospectively collected baseline demographic data such as age, race, body mass index (BMI, serum prostate specific antigen, prostate volume, Gleason score, percentage cancer, TNM clinical staging, and comorbidities. Urinary symptoms were measured with the international prostate symptom score (IPSS, and sexual health with the sexual health inventory of males (SHIM. In addition, the patients were mailed the expanded prostate inventory composite at baseline and at 1, 3, 6, 12 and 18 months after the procedure. Results: Gleason seven or more cancer grade was noted in 33.5% of patients. The average BMI was high (27.7 and 87% patients had pathological stage PT2a-b. The mean operative time was 160 min and the mean blood loss was 153 cm3. No patient required blood transfusion. At 6 months 82% of the men who were younger and 75% of those older than 60 years had return of sexual

    Eighty-four women at high risk for ovarian cancer by having first-degree relatives with epithelial ovarian cancer participated in a newly established, early ovarian cancer detection program at Yale University. Participants were to be evaluated with physical examinations and circulating tumor markers at entry and every six months thereafter. Endovaginal ultrasound and color Doppler flow studies were to be performed at three and nine months following entry into the program. In addition, women were encouraged to follow American Cancer Society guidelines for mammography. Stool was checked for occult blood. Endometrial sampling was offered to post-menopausal women. No participant has developed an ovarian cancer since entering the program. One woman has been diagnosed to have breast cancer. False-positive levels of circulating tumor markers (CA 125, 4/84 [4.8 percent]; lipid-associated sialic acid in plasma, 13/84 [15.5 percent]; NB/70K, 4/84 [4.8 percent]; and urinary gonadotropin fragment, 1/65 [1.5 percent]) were observed on entry into the program. Low resistive indices (less than 0.5) were documented in 8/91 (8.8 percent) ovaries studied by the color Doppler flow technique. One participant underwent a laparotomy based on a false-positive endovaginal ultrasound examination. Tests now being employed in community practice have a high likelihood of being associated with false-positive results. Therapeutic interventions based on isolated abnormal tumor markers or ultrasound studies obtained from women with family histories of ovarian cancer may lead to inappropriate surgery. It is necessary for cancer centers to develop expertise in ovarian cancer detection techniques to advise physicians in their geographic areas appropriately about the significance of the abnormal screening test.

    The relationship between excess body weight and gastric cancer risk has not been well studied to date. We therefore carried out a systematic review and meta-analysis of published cohort studies to evaluate the association between excess body weight and gastric cancer risk. An electronic search of the MEDLINE, PubMed, EMBASE and Academic Search Premier (EBSCO) databases, which contain articles published from 1950 onwards, was conducted in order to select studies for this meta-analysis. Ten studies with a total number of 9492 gastric cancer cases and a studied population of 3,097,794 were identified. Overall, excess body weight [body mass index (BMI)25] was associated with an increased risk of gastric cancer [odds ratio (OR)=1.22; 95% confidence intervals (CIs)=1.06-1.41]. Specifically, a stratified analysis showed that excess body weight was associated with an increased risk of cardia gastric cancer [overweight and obese (BMI 25), OR=1.55, 95% CIs=1.31-1.84] and gastric cancer among non-Asians (overweight and obese, OR=1.24, 95% CIs=1.14-1.36); however, the stratified analysis also showed that there was no statistically significant link between excess body weight and gastric cancer in the following subgroups: males (overweight and obese, OR=1.22, 95% CIs=0.96-1.55), females (overweight and obese, OR=1.13, 95% CIs=0.65-1.94), non-cardia gastric cancer (overweight and obese, OR=1.18, 95% CIs=0.96-1.45) and Asians (overweight and obese, OR=1.17, 95% CIs=0.88-1.56). The combined results of this meta-analysis, however, do indicate that overweight and obesity are associated with an increased risk of gastric cancer. The strength of the association also increases with increasing BMI.

    BACKGROUND: Findings from the few epidemiological studies that have investigated thyroid cancer risk after fertility drugs have been inconclusive. Using data from the largest cohort of infertile women to date, we examined the effects of fertility drugs on thyroid cancer risk. METHODS: A cohort...... of 54 362 women with infertility problems referred to Danish fertility clinics in the period 1963-1998 was established. A detailed data collection including information about type and amount of treatment was conducted. Using case-cohort techniques, we calculated rate ratios (RRs) of thyroid cancer...... associated with different fertility drugs after adjustment for age at first live birth. RESULTS: A total of 29 thyroid cancers were identified during follow-up through 2000. Use of clomiphene [RR = 2.28; 95% confidence interval (CI): 1.08-4.82] or progesterone (RR = 10.14; 95% CI: 1.93-53.33) was associated...

    To assess trends in occupational cancer epidemiology research through a literature review of occupational health and epidemiology journals. Fifteen journals were reviewed from 1991 to 2009, and characteristics of articles that assessed the risk of cancer associated with an occupation, industry, or occupational exposure, were incorporated into a database. The number of occupational cancer epidemiology articles published annually declined in recent years (2003 onwards) in the journals reviewed. The number of articles presenting dose-response analyses increased over the review period, from 29% in the first 4 years of review to 49% in the last 4 years. There has been a decrease in the number of occupational cancer epidemiology articles published annually during the review period. The results of these articles help determine the carcinogenicity of workplace exposures and permissible exposure limits, both of which may be hindered with a decline in research. © 2013 Wiley Periodicals, Inc.

    2007-01-01

    This report presents the results of supplementary comparison APMP.M.H-S1 among four national metrology institutes (NIMT, NMIJ/AIST, VMI and SPRING). The comparison was carried out during October 2004 to January 2005 in order to determine the capability of the primary Rockwell hardness standard, including standard conditions, of each participant, to confirm the accuracy of Rockwell hardness scale C measurement declared by the participant, which includes the effect of each participant's primary indenter and determine the degrees of equivalence of hardness scale measurement in the range 20 HRC to 60 HRC. Furthermore, the comparison was carried out a by common indenter, which was provided by the pilot institute, in order to determine the measurement capability of the participant's primary machine without the influence of the indenter, as a study of scientific purpose. The pilot institute was the National Institute of Metrology (Thailand), NIMT. There were two sets of artifacts for the comparison. Each set was composed of nine hardness blocks: 20 HRC, 25 HRC, 30 HRC, 35 HRC, 40 HRC, 45 HRC, 50 HRC, 55 HRC, 60 HRC. The verification of the participant's primary Rockwell hardness machine was carried out according to ISO6508-3 before making the measurement. The pilot institute made measurements at the beginning and the end of the comparison in order to monitor the stability of the artifacts. The degree of equivalence of each national primary hardness standard was expressed quantitatively by two terms, the deviation from KCRV and the uncertainty of this deviation at a 95% level of confidence. The En parameter was calculated to express the equivalence between the measurements of participants as well. The degree of equivalence between pairs of participating institutes was expressed by the difference of their deviations from the key comparison reference value and the uncertainty of this difference at the 95% level of confidence.

    1990-03-01

    The relation between diazepam use and breast cancer was explored in two case-control studies. The first (1981-1987) was a hospital-based study in the United States of 3,078 cases of breast cancer, 1,259 controls with other malignancies, and 672 controls with nonmalignant conditions. The relative risk estimates for regular diazepam use (at least 4 days per week for at least 6 months) that antedated the diagnosis of breast cancer by at least 12 months were 1.0 (95% confidence interval (CI) 0.6-1.7) using the cancer controls and 0.8 (95% CI 0.4-1.8) using the noncancer controls. Risk factors for breast cancer were taken into account in the estimates. There was no association for regular use lasting at least 5 years or for regular use that took place exclusively in the recent or more distant past. The second study (1982-1986), conducted in Toronto, Ontario, Canada, was community-based, and included 607 cases of breast cancer and 1,214 neighbor controls selected from municipal voting and census records. After control of confounding, the relative risk estimate for regular diazepam use was 0.8 (95% CI 0.5-1.3). Again, there was no association for long-term, past, or recent regular use. The results of both studies suggest that regular diazepam use does not increase the risk of breast cancer. The findings are strengthened by the similarity of the results using three different control groups--women with cancer, women with nonmalignant conditions, and neighbors.

    Cancer stem cells (CSC) have raised great excitement during the last decade and are promising targets for an efficient treatment of tumors without relapses and metastases. Among the various methods that enable to enrich cancer cell lines in CSC, tumorspheres culture has been predominantly used. In this report, we attempted to generate tumorspheres from several murine and human cancer cell lines: B16-F10, HT-29, MCF-7 and MDA-MB-231 cells. Tumorspheres were obtained with variable efficiencies from all cell lines except from MDA-MB-231 cells. Then, we studied several CSC characteristics in both tumorspheres and adherent cultures of the B16-F10, HT-29 and MCF-7 cells. Unexpectedly, tumorspheres-forming cells were less clonogenic and, in the case of B16-F10, less proliferative than attached cells. In addition, we did not observe any enrichment in the population expressing CSC surface markers in tumorspheres from B16-F10 (CD133, CD44 and CD24 markers) or MCF-7 (CD44 and CD24 markers) cells. On the contrary, tumorspheres culture of HT-29 cells appeared to enrich in cells expressing colon CSC markers, i.e. CD133 and CD44 proteins. For the B16-F10 cell line, when 1 000 cells were injected in syngenic C57BL/6 mice, tumorspheres-forming cells displayed a significantly lower tumorigenic potential than adherent cells. Finally, tumorspheres culture of B16-F10 cells induced a down-regulation of vimentin which could explain, at least partially, the lower tumorigenicity of tumorspheres-forming cells. All these results, along with the literature, indicate that tumorspheres culture of cancer cell lines can induce an enrichment in CSC but in a cell line-dependent manner. In conclusion, extensive characterization of CSC properties in tumorspheres derived from any cancer cell line or cancer tissue must be performed in order to ensure that the generated tumorspheres are actually enriched in CSC.

    The purpose of this study is to determine the degree of satisfaction of users of the Cancer Information Point section of the Library for Patients (CIP-LP), active since 1998 at the National Cancer Institute of Aviano, Italy. The CIP-LP is based on a skilled intermediary, adequate informative material and a specific location, within the Scientific Library of the Institute. A survey was developed to assess service functionality and quality from the users' viewpoint. During a 6-month period, a questionnaire was mailed to 194 patients and relatives who previously used the CIP-LP; 113 (58%) were returned and processed. Of the respondents, 91% were pleased with the CIP-LP and 95% would recommend the service to other people. The information obtained contributed to a clearer understanding of the illness and treatment (45% as first answer) and a better control of the situation (33%). Fifty-one per cent evaluated the information received as 'good', 42%'excellent' and 4%'of sufficient quality'. This survey shows the appreciation and usefulness in the users' perception of a specific hospital library for cancer patients and their relatives, providing an information service supplementary to doctor-patient communication.

  16. Spatiotemporal Effects of Supplementary Feeding of Wild Boar (Sus scrofa on Artificial Ground Nest Depredation.

    Full Text Available Supplementary feeding of ungulates, being widely used in game management, may have unwanted consequences. Its role in agricultural damage is well-studied, but few studies have considered the potential for the practice to attract ground nest predators. Our goal was to identify the factors influencing ground nest predation in the vicinity of year-round supplementary feeding sites for wild boar and to characterise their spatiotemporal scope. We conducted two separate artificial ground nest experiments in five different hunting districts in south-eastern Estonia. The quantity of food provided and distance of a nest from the feeding site were the most important factors determining predation risk. Larger quantities of food resulted in higher predation risk, while predation risk responded in a non-linear fashion to distance from the feeding site. Although predation risk eventually decreases if supplementary feeding is ceased for at least four years, recently abandoned feeding sites still pose a high predation risk.

    This study examined the effects of an asynchronous Web-based supplementary learning program on the performance of nursing students' basic nursing skills. A posttest quasi-experimental design was used. Students in the intervention group (n = 62) were given login information to access the online program, while the control group (n = 99) was not. Data from both groups were collected before and 4 weeks after the intervention. An objective assessment of basic nursing skills was used to evaluate the level of skill demonstrated by the participants. Results indicate that the Web-based supplementary learning program is effective at strengthening students' basic nursing skills (P = .002). The findings also reveal that students in the intervention group showed higher-than-average satisfaction with the supplementary program (mean, 3.80 [SD, 0.81]). Thus, this Web-based program offers a learning opportunity for nursing students to enhance their skills beyond their formal lectures.

    Considerable effort has been devoted to the identification of cost-effective approaches to screening for ovarian cancer (OC). Transvaginal ultrasound (TVS) is one such screening approach. Approximately 5-7% of routine TVS screening tests yield abnormal results. Some women experience significant distress after receipt of an abnormal TVS screening test. Four focus groups provided in-depth, qualitative data regarding the informational, psychological, and practical needs of women after the receipt of an abnormal TVS result. Through question and content analytic procedures, we identified four themes: anticipation, emotional response, role of the screening technician, and impact of prior cancer experiences. Results provide initial guidance toward development of interventions to promote adaptive responses after receipt of an abnormal cancer screening test result.

    AIM: Liver metastases from breast cancer (BCLM) are associated with poor prognosis. Cytotoxic chemotherapy can result in regression of tumor lesions and a decrease in symptoms. Available data, in the literature, also suggest a subgroup of patients rraay berefit from surgery, but few talked about transcatheter arterial chemoembolization (TACE).We report the results of TACE and systemic chemotherapy for patients with liver metastases from breast cancer and evaluate the prognostic factors. METHODS: Forty-eight patients with liver metastases, from proved breast primary cancer were treated with TACEor systemic chemotherapy between January 1995 and December 2000. Treatment results were assessed according to WHO criteria, along with analysis of prognostic factors for survival using Cox regression model.RESULTS: The median follow-up was 28 mo (1-72 mo). Response rates were calculated for the TACE group and chemotherapy group, being 35.7% and 7.1%,respectively. The difference was significant. The one-, two- and three-year Survival rates for the TACE group were 63.04%, 30.35%, and 13.01%, and those for the systemic chemotherapy group were 33.88%, 11.29%, and 0%. According to univariate analysis, variables significantly associated with survival were the lymph node status of the primary cancer, the clinical stage of liver metastases, the Child-Pugh grade, loss of weight. Other factors such as age, the intervals between the primary to the metastases, the maximal diameter of the liver metastases, the number of liver metastases, extrahepatic metastasis showed no prognostic significances. These factors mentioned above such as the lymph node status of the primary cancer, the clinical stage of liver metastases, the Child-Pugh grade, loss of weight were also independent factors in multivariate analysis.CONCLUSION: TACE treatment of liver metastases from breast cancer may prolong survival in certain patients. This approach offers new promise for the curative treatment of the patients

    To determine whether induced abortion (IA) increases breast cancer (BC) risk. A population-based case-control study was performed from Dec, 2000 to November, 2004 in Shanghai, China, where IA could be verified through the family planning network and client medical records. Structured questionnaires were completed by 1,517 cases with primary invasive epithelial breast cancer and 1,573 controls frequency- matched to cases for age group. The information was supplemented and verified by the family planning records. Statistical analysis was conducted with SAS 9.0. After adjusting for potential confounders, induced abortions were not found to be associated with breast cancer with OR=0.94 (95%CI= 0.79-1.11). Compared to parous women without induced abortion, parous women with 3 or more times induced abortion (OR=0.66, 95%CI=0.46 to 0.95) and women with 3 or more times induced abortion after the first live birth (OR=0.66, 95%CI =0.45 to 0.97) showed a lower risk of breast cancer, after adjustment for age, level of education, annual income per capita, age at menarche, menopause, parity times, spontaneous abortion, age at first live birth, breast-feeding, oral contraceptives, hormones drug, breast disease, BMI, drinking alcohol, drinking tea, taking vitamin/calcium tablet, physical activity, vocation, history of breast cancer, eating the bean. The results suggest that a history of induced abortions may not increase the risk of breast cancer.

    A simple modification of typical content-based visual information retrieval (CBVIR) techniques (e.g. MSER keypoints represented by SIFT descriptors quantized into sufficiently large vocabularies) is discussed and preliminarily evaluated. By using the approximate depths (as the supplementary data) of the detected keypoints, we can significantly improve credibility of keypoint matching so that known objects (i.e. objects for which exemplary images are available in the database) can be detected at low computational costs. Thus, the method can be particularly useful in real-time applications of machine vision systems (e.g. in intelligent robotic devices). The paper presents theoretical model of the method and provides exemplary results for selected scenarios.

    In this article we review the most significant published papers on active surveillance in prostate cancer and present the results of our case series. We used as main response variables the percentage of patients remaining in surveillance and the oncological results presented as global, cancer specific and metastasis free survivals. Globally, in published series 71.2% of patients included in active surveillance programs, 10-year overall survival is 68% in the series with longer follow up, and cancer-specific survival varies from 97% to 100%. In our series of 144 patients with median follow up of 3.2 years, 76.3% of the patients continue on surveillance. 24 patients (15.9%) stopped surveillance due to histological progression. 5 patients (21.3%) out of the 23 undergoing surgery presented unfavorable pathological criteria on prostatectomy specimen. No patient has died or developed metastases.

  5. Yoga for Persistent Fatigue in Breast Cancer Survivors: Results of a Pilot Study

    Directory of Open Access Journals (Sweden)

    Julienne E. Bower

    2011-01-01

    Full Text Available Approximately one-third of breast cancer survivors experiences persistent fatigue for months or years after successful treatment completion. There is a lack of evidence-based treatments for cancer-related fatigue, particularly among cancer survivors. This single-arm pilot study evaluated the feasibility and preliminary efficacy of a yoga intervention for fatigued breast cancer survivors based on the Iyengar tradition. Iyengar yoga prescribes specific poses for individuals with specific medical problems and conditions; this trial emphasized postures believed to be effective for reducing fatigue among breast cancer survivors, including inversions and backbends performed with the support of props. Twelve women were enrolled in the trial, and 11 completed the full 12-week course of treatment. There was a significant improvement in fatigue scores from pre- to post-intervention that was maintained at the 3-month post-intervention followup. Significant improvements were also observed in measures of physical function, depressed mood, and quality of life. These results support the acceptability of this intervention and suggest that it may have beneficial effects on persistent post-treatment fatigue. However, results require replication in a larger randomized controlled trial.

    The objective of this study was to examine the effects of Tithonia diversifolia as a supplementary forage on dairy cow performance and methane production. Nine lactating Holstein × Zebu dairy cows (519 ± 53.3 kg of body weight and 66 ± 13.3 d in milk) were paired by milk yield (21.3 ± 2.34 kg/d) and body weight and randomly assigned to three dietary treatments in a Latin square design with 21-d experimental periods (14 d for diet adaptation and 7 d for measurements and sample collection). The dietary treatments included the control diet consisting of fresh sugar cane plus concentrate (44:56, % of diet DM), and two treatment diets containing different levels of fresh T. diversifolia (6.5 and 15.4%, DM basis) which partially replaced both sugarcane and concentrates. Methane production was measured using the sulphur hexafluoride (SF6) technique from d 16 to d 21 of each experimental period. Analysis of the gas samples was performed by gas chromatography. The inclusion of T. diversifolia at 15.4% DM had no effects on DM intake, milk production, nitrogen balance or methane production. There was no effect on the concentrations of total saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA) in milk fat (P ≥ 0.28), though individual milk fatty acids were affected. Serum concentrations of glucose, urea nitrogen (BUN), triglycerides, β-hydroxybutyrate (BHBA), and cholesterol were unaffected by the dietary treatments (P ≥ 0.13). There was a time (2 and 6 h post-feeding) and dietary treatment effect (P < 0.01) on the acetate to propionate ratio in the rumen. A denaturing gradient gel electrophoresis analysis of the archaeal community showed distinct clustering of the archaea populations for control and treatment diets. Taken together, our results indicate the potential of T. diversifolia as a supplementary forage for dairy cattle in the tropics. PMID:27906983

This analysis examines the trends in cancer mortality across this 25-year challenge period from 1990 to 2015. In 2015, cancer death rates were 26% lower than in 1990 (32% lower among men and 22% lower among women). The 50% reduction goal was more fully met for the cancer sites for which there was enactment of effective approaches for prevention, early detection, and/or treatment. Among men, mortality rates dropped for lung cancer by 45%, for colorectal cancer by 47%, and for prostate cancer by 53%. Among women, mortality rates dropped for lung cancer by 8%, for colorectal cancer by 44%, and for breast cancer by 39%. Declines in the death rates of all other cancer sites were substantially smaller (13% among men and 17% among women). The major factors that accounted for these favorable trends were progress in tobacco control and improvements in early detection and treatment. As we embark on new national cancer goals, this recent past experience should teach us that curing the cancer problem will require 2 sets of actions: making new discoveries in cancer therapeutics and more completely applying those discoveries in cancer prevention we have already made.

    Purpose To assess the risk of breast cancer in women with false-positive screening results according to radiologic classification of mammographic features. Materials and Methods Review board approval was obtained, with waiver of informed consent. This retrospective cohort study included 521 200 women aged 50-69 years who underwent screening as part of the Spanish Breast Cancer Screening Program between 1994 and 2010 and who were observed until December 2012. Cox proportional hazards regression analysis was used to estimate the age-adjusted hazard ratio (HR) of breast cancer and the 95% confidence interval (CI) in women with false-positive mammograms as compared with women with negative mammograms. Separate models were adjusted for screen-detected and interval cancers and for screen-film and digital mammography. Time without a breast cancer diagnosis was plotted by using Kaplan-Meier curves. Results When compared with women with negative mammograms, the age-adjusted HR of cancer in women with false-positive results was 1.84 (95% CI: 1.73, 1.95; P < .001). The risk was higher in women who had calcifications, whether they were (HR, 2.73; 95% CI: 2.28, 3.28; P < .001) or were not (HR, 2.24; 95% CI: 2.02, 2.48; P < .001) associated with masses. Women in whom mammographic features showed changes in subsequent false-positive results were those who had the highest risk (HR, 9.13; 95% CI: 8.28, 10.07; P < .001). Conclusion Women with false-positive results had an increased risk of breast cancer, particularly women who had calcifications at mammography. Women who had more than one examination with false-positive findings and in whom the mammographic features changed over time had a highly increased risk of breast cancer. Previous mammographic features might yield useful information for further risk-prediction models and personalized follow-up screening protocols.

    Background and Purpose: Neoadjuvant androgen deprivation in combination with radiotherapy of prostate cancer is used to improve radioresponsiveness and local tumor control. Currently, the underlying mechanism is not well understood. Because hypoxia causes resistance to radiotherapy, we wanted to test whether castration affects the degree of hypoxia in prostate cancer. Methods and Materials: In 14 patients with locally advanced prostate cancer, six to 12 prostatic needle core biopsy specimens were taken prior to castration therapy. Bilateral orchidectomy was performed in 7 patients, and 7 were treated with a GnRH-agonist (leuprorelin). After castrationm two to four prostatic core biopsy specimens were taken, and the level of hypoxia-inducible factor-1{alpha} (HIF-1{alpha}) in cancer was determined by immunofluorescence. Results: Among biopsy specimens taken before castration, strong HIF-1{alpha} expression (mean intensity above 30) was shown in 5 patients, weak expression (mean intensity 10-30) in 3 patients, and background levels of HIF-1{alpha} (mean intensity 0-10) in 6 patients. Downregulation of HIF-1{alpha} expression after castration was observed in all 5 patients with strong HIF-1{alpha} precastration expression. HIF-1{alpha} expression was also reduced in 2 of 3 patients with weak HIF-1{alpha} precastration expression. Conclusions: Our data suggest that neoadjuvant castration decreases tumor cell hypoxia in prostate cancer, which may explain increased radiosensitivity after castration.

    Breast cancer mass screening by mobile units started in 1992 in the Province of Liège (Belgium). This project is developed for rural areas and interests all women between 40-69 years old not regularly X-rayed in traditional breast cancer diagnosis centers. Despite lots of efforts population participation is low (25%). Nevertheless, the experiment results are encouraging: in a series of 31,443 women, 213 cancers were diagnosed, corresponding to a rate of 6.9/1000, 75% of which are of good prognosis. After an 8 years experiment, it is hoped that the population concerned becomes more sensitive to this mass screening project and one should expect a better collaboration with the other actors in the field of breast diseases diagnosis.

  15. The culture of cancer cell lines as tumorspheres does not systematically result in cancer stem cell enrichment.

    Full Text Available Cancer stem cells (CSC have raised great excitement during the last decade and are promising targets for an efficient treatment of tumors without relapses and metastases. Among the various methods that enable to enrich cancer cell lines in CSC, tumorspheres culture has been predominantly used. In this report, we attempted to generate tumorspheres from several murine and human cancer cell lines: B16-F10, HT-29, MCF-7 and MDA-MB-231 cells. Tumorspheres were obtained with variable efficiencies from all cell lines except from MDA-MB-231 cells. Then, we studied several CSC characteristics in both tumorspheres and adherent cultures of the B16-F10, HT-29 and MCF-7 cells. Unexpectedly, tumorspheres-forming cells were less clonogenic and, in the case of B16-F10, less proliferative than attached cells. In addition, we did not observe any enrichment in the population expressing CSC surface markers in tumorspheres from B16-F10 (CD133, CD44 and CD24 markers or MCF-7 (CD44 and CD24 markers cells. On the contrary, tumorspheres culture of HT-29 cells appeared to enrich in cells expressing colon CSC markers, i.e. CD133 and CD44 proteins. For the B16-F10 cell line, when 1 000 cells were injected in syngenic C57BL/6 mice, tumorspheres-forming cells displayed a significantly lower tumorigenic potential than adherent cells. Finally, tumorspheres culture of B16-F10 cells induced a down-regulation of vimentin which could explain, at least partially, the lower tumorigenicity of tumorspheres-forming cells. All these results, along with the literature, indicate that tumorspheres culture of cancer cell lines can induce an enrichment in CSC but in a cell line-dependent manner. In conclusion, extensive characterization of CSC properties in tumorspheres derived from any cancer cell line or cancer tissue must be performed in order to ensure that the generated tumorspheres are actually enriched in CSC.

    AIM: To determine current day-to-day practice of and access to preoperative MRI for patients with rectal cancer in the UK, with the aim of identifying constraining factors. MATERIALS AND METHODS: A questionnaire asking for details of rectal cancer workload, multidisciplinary team (MDT) practice, preoperative MRI, the use of alternative imaging methods where appropriate, and an assessment of local access to MRI, was mailed to 283 UK departments of radiology. Replies were received from 142 departments (50.2% response rate). These were collated and response frequencies were determined. RESULTS: According to their replies, 135 (95%) of respondents always discussed rectal cancer cases within the context of an MDT, usually including a radiologist. Only 49% of respondents attempted to offer preoperative MRI to all rectal cancer patients, and 35% of respondents used MRI in less than 25% of cases. Of the 142 respondents, 73 (51%) felt their practice was currently constrained by lack of MR resources. The most frequently cited constraint was an available but over-subscribed MRI scanner. Limited radiology manpower was the next most frequently cited constraint. A significant minority stated that no MRI scanner was available. CONCLUSIONS: The MDT is a well established forum for the discussion of patients with rectal cancer, and a radiologist is usually involved. However, in the face of current guidelines, less than 50% of the units studied were able to offer preoperative MRI to all of their rectal cancer cases. Improved access to MRI and increased radiological manpower are necessary if current management guidelines are to be observed.

    Purpose: DNA damage defects are common in ovarian cancer and can be used to stratify treatment. Although most work has focused on homologous recombination (HR), DNA double-strand breaks are repaired primarily by nonhomologous end joining (NHEJ). Defects in NHEJ have been shown to contribute to genomic instability and have been associated with the development of chemoresistance.Experimental Design: NHEJ was assessed in a panel of ovarian cancer cell lines and 47 primary ascetic-derived ovarian cancer cultures, by measuring the ability of cell extracts to end-join linearized plasmid monomers into multimers. mRNA and protein expression of components of NHEJ was determined using RT-qPCR and Western blotting. Cytotoxicities of cisplatin and the PARP inhibitor rucaparib were assessed using sulforhodamine B (SRB) assays. HR function was assessed using γH2AX/RAD51 foci assay.Results: NHEJ was defective (D) in four of six cell lines and 20 of 47 primary cultures. NHEJ function was independent of HR competence (C). NHEJD cultures were resistant to rucaparib (P = 0.0022). When HR and NHEJ functions were taken into account, only NHEJC/HRD cultures were sensitive to rucaparib (compared with NHEJC/HRC P = 0.034, NHEJD/HRC P = 0.0002, and NHEJD/HRD P = 0.0045). The DNA-PK inhibitor, NU7441, induced resistance to rucaparib (P = 0.014) and HR function recovery in a BRCA1-defective cell line.Conclusions: This study has shown that NHEJ is defective in 40% of ovarian cancers, which is independent of HR function and associated with resistance to PARP inhibitors in ex vivo primary cultures.

    The proposed implementation of work hour restrictions has presented a significant challenge of maintaining the quality of resident education and ensuring adequate hands-on experience that is essential for novice surgeons. To maintain the level of resident surgical competency, revision of the apprentice model of surgical education to include supplementary educational methods, such as laboratory and virtual reality (VR) simulations, have become frequent topics of discussion. We aimed to better understand the role of supplementary educational methods in Canadian neurosurgery residency training. An online survey was sent to program directors of all 14 Canadian neurosurgical residency programs and active resident members of the Canadian Neurosurgical Society (N=85). We asked 16 questions focusing on topics of surgeon perception, current implementation and barriers to supplementary educational models. Of the 99 surveys sent, 8 out of 14 (57%) program directors and 37 out of 85 (44%) residents completed the survey. Of the 14 neurosurgery residency programs across Canada, 7 reported utilizing laboratory-based teaching within their educational plan, while only 3 programs reported using VR simulation as a supplementary teaching method. The biggest barriers to implementing supplementary educational methods were resident availability, lack of resources, and cost. Work-hour restrictions threaten to compromise the traditional apprentice model of surgical training. The potential value of supplementary educational methods for surgical education is evident, as reported by both program directors and residents across Canada. However, availability and utilization of laboratory and VR simulations are limited by numerous factors such as time constrains and lack of resources.

    2010-01-01

    Introduction Endometrial cancer patients with high grade tumours, deep myometrial invasion, or advanced stage disease have a poor prognosis. Randomized studies have demonstrated prevention of loco-regional relapses with radiotherapy with no effect on overall survival. The possible additive effect of chemotherapy remains unclear. Two randomized clinical trials (NSGO-EC-9501/EORTC-55991 and MaNGO ILIADE-III) were undertaken to clarify if sequential combination of chemotherapy and radiotherapy improves progression-free survival in high-risk endometrial cancer. The two studies were pooled. Methods Patients (n=540; 534 evaluable) with operated endometrial cancer FIGO stage I-III with no residual tumour and prognostic factors implying high-risk were randomly allocated to adjuvant radiotherapy with or without sequential chemotherapy. Results In the NSGO/EORTC study, combined modality treatment was associated with a 36 % reduction in the risk for relapse or death (HR 0.64, 95 % CI 0.41-0.99; P=0.04); two-sided tests were used. The result from the MaNGO-study pointed in the same direction (HR 0.61), but was not significant. In combined analysis, the estimate of risk for relapse or death was similar but with narrower confidence limits (HR 0.63, CI 0.44-0.89; P=0.009). Neither study showed significant differences in overall survival. In combined analysis, overall survival approached statistical significance (HR 0.69, CI 0.46-1.03; P = 0.07) and cancer-specific survival was significant (HR 0.55, CI 0.35-0.88; p=0.01). Conclusion Addition of adjuvant chemotherapy to radiation improves progression-free survival in operated endometrial cancer patients with no residual tumour and high risk profile. A remaining question for future studies is if addition of radiotherapy to chemotherapy improves the results. PMID:20619634

    Digital access to chemical journals resulted in a vast array of molecular information that is now available in the supplementary material files in PDF format. However, extracting this molecular information, generally from a PDF document format is a daunting task. Here we present an approach to harvest 3D molecular data from the supporting information of scientific research articles that are normally available from publisher's resources. In order to demonstrate the feasibility of extracting truly computable molecules from PDF file formats in a fast and efficient manner, we have developed a Java based application, namely ChemEngine. This program recognizes textual patterns from the supplementary data and generates standard molecular structure data (bond matrix, atomic coordinates) that can be subjected to a multitude of computational processes automatically. The methodology has been demonstrated via several case studies on different formats of coordinates data stored in supplementary information files, wherein ChemEngine selectively harvested the atomic coordinates and interpreted them as molecules with high accuracy. The reusability of extracted molecular coordinate data was demonstrated by computing Single Point Energies that were in close agreement with the original computed data provided with the articles. It is envisaged that the methodology will enable large scale conversion of molecular information from supplementary files available in the PDF format into a collection of ready- to- compute molecular data to create an automated workflow for advanced computational processes.

    The goal of the epidemiological research is to assess stochastic (carcinogenic) effects for an unselected general population exposed to radioactive materials released by the Mayak atomic facility in the Southern Urals, Russia. The discharges of radioactive waste into the Techa River from 1950 through 1956 brought about exposures of riverside residents for whom the river was the main water source. This paper presents the results of the activities carried on by the URCRM researchers for several decades with the aim to follow-up the population exposed in the Southern Urals, develop specific methods for collecting and constantly updating the vital status information (since 1950) and following-up cancer incidence and mortality. These activities provided a basis for creating a unified computerized medical-dosimetric exposed-population registry, and identifying a cohort for epidemiological analysis. The paper includes information on the vital status of the cohort numbering about 18,000 exposed residents of the Techa riverside villages in chelyabinsk oblast for the period from 1956 through 1999, a characterization of the catchment area, and an analysis of the completeness of quality of data on cancer incidence, i. e. data that serve as a basis for computing the number person-years at risk and estimating the dose-dependent risk of cancer incidence for Techa cohort member. A preliminary analysis has shown a statistically significant dependence of cancer incidence on dose. (Author) 6 refs.

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

    The increasingly early diagnosis of prostate cancer requires a search for therapeutic alternatives with good oncological results that in turn facilitate a good long-term quality of life. This review analyses 2 minimally invasive therapies for treating localised prostate cancer in terms of oncological and functional results, as well as the complications resulting from the therapies. A systematic literature review was conducted of the treatment of localised prostate cancer with 2 ablative techniques as the primary therapy: cryosurgery or cryotherapy and high intensity focused ultrasound (HIFU). We included patients who underwent procedures that included the entire gland, with hemiablation or focal therapy, which were indicated for low to intermediate-risk prostate cancer according to the D'Amico criteria. We excluded patients with high-risk prostate cancer and those who underwent any prior treatment for prostate cancer. After conducting the literature search and excluding the studies that did not meet the protocol criteria, we reviewed a total of 14 studies, with a total of 350 patients treated using cryotherapy and 1107 treated with HIFU. All studies were either prospective or retrospective and were not randomised. The patients' mean age was younger than 75 years. Overall, the rate of disease recurrence in the patients treated with cryotherapy varied between 13.2% and 26%, while the rate for those treated with HIFU varied between 7.3% and 67.9%. The overall demonstrated continence at 12 months was 97.6-100% for cryotherapy and 96-100% for HIFU. In terms of sexual potency rates, cryotherapy showed complete potency at 12 months for 86-100% of the patients treated with focal cryotherapy and slightly lower rates for hemiablation (76.9-100%) and total therapy (39%). HIFU showed potency rates of 89%, 52-80% and 33-78% for focal therapy, hemiablation and total therapy, respectively. Both techniques have comparable functional results, although the somewhat poorer

    A totally satisfying concept of treatment is not easy to formulate from the complex and often conflicting results of local therapeutic interventions for breast cancer. It seems evident that clinically occult cancer is often beyond the pale of both resection and irradiation at primary treatment, particularly when cancer is found in regional lymph nodes. Despite all combinations of local treatment, the ultimate risk of failure correlates more closely with the stage of the disease at the time of treatment than with the particular form of treatment. Thus the extent of disease must be considered the major, perhaps the ultimate determinant of prognosis. Because, under controlled conditions, several therapeutic alternatives have appeared to provide virtually identical end results in terms of survival and ultimate dissemination of the disease, the adequacy of control within the field of treatment may, in fact, be the most meaningful end result of local treatment. The experience that has accumulated with treatment of breast cancer supports the thesis that removal of the breast accomplishes all that can be achieved in terms of curing the disease, and wider treatment with surgery or irradiation serves only to improve the prospects for local control. Halsted demonstrated this principle with his radical mastectomy and it still seems to be the case. This fact provides further impetus for detecting and treating cancer while it is still localized to the breast. With these generalizations in mind some empirical observations can be added. An anatomic fact is that multiple microscopic foci of cancer that are not evident clinically are often present in the mammary parenchyma. Undisturbed, at least some, and perhaps eventually all, of these foci of cancer progress to become clinical cancers. Thorough removal of the entire breast (the entire mammary parenchyma) eliminates this particular hazard and, one may presume, terminates the disease if it is still limited to the breast. Removal of

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    AIM: To examine how the introduction of endoscopy to gastric cancer screening affected survival prognosis in a regional population.METHODS: The subjects comprised 4261 residents of Kamigoto, Nagasaki Prefecture, who underwent gastric X-ray examination for gastric cancer screening from 1991 to 1995, and all 7178 residents who underwent endoscopic examination for the same purpose from 1996to 2003. The analysis evaluated trends in age-adjusted gastric cancer mortality rates and standard mortality ratios (SMRs) among the Kamigoto residents.RESULTS: According to demographic statistics, the 1995 and 2000 age-adjusted gastric cancer mortality rates in Nagasaki Prefecture (per 100000 population) were 42.6 and 37.3 for males and 18.6 and 16.0 for females, while the corresponding rates in Kamigoto before and after the introduction of endoscopic screening were respectively 51.9 and 28.0, and 26.6 and 6.9. The data obtained in this study were divided into those for two periods,1990-1996 and 1997-2006, and SMRs were calculated separately for males and females. For the first period,the SMR was 1.04 (95% CI 0.50-1.58) for males and 1.54(95% CI 0.71-2.38) for females, while for the second period the SMR was 0.71 (95% CI 0.33-1.10) for males and 0.62 (95% CI 0.19-1.05) for females.CONCLUSION: Following the introduction of endoscopic examination, gastric cancer death rates decreased in Kamigoto.

    Findings from studies of metformin use with risk of cancer incidence and outcome provide mixed results; with few studies examined associations by recency of diabetes diagnosis or duration of medication use. Thus, in the Women's Health Initiative, we examined these associations and further explored whether associations differ by recency of diabetes and duration of metformin use. Cox regression models were used to estimate hazard ratios (HR) and their 95% confidence intervals. Diabetes was associated with higher risk of total invasive cancer (HR, 1.13; p metformin users, compared to users of other medications, relative to women without diabetes, overall (HRs, 1.08 vs. 1.45; p = 0.007) and for breast cancer (HRs, 0.50 vs. 1.29; p = 0.05). Results also suggested that lower cancer risk associated with metformin may be evident only for a longer duration of use in certain cancer sites or subgroup populations. We provide further evidence that postmenopausal women with diabetes are at higher risk of invasive cancer and cancer death. Metformin users, particularly long-term users, may be at lower risk of developing certain cancers and dying from cancer, compared to users of other anti-diabetes medications. Future studies are needed to determine the long-term effect of metformin in cancer risk and survival from cancer.

    Reliability and credibility of research conducted by industry have been questioned, including in the field of occupational health. Cohort studies on occupational cancer published between 2000 and 2010 were compared according to their results, their conclusions, their funding, and the affiliation of their authors. Overall, 510 articles were included. Studies published by authors with public affiliation or funded by public grants concluded that their study showed an excess of cancer more frequently (P = 0.01) than studies published by authors with private affiliation or funded by private grants (88% [95%CI = 85-91] vs. 73% [95%CI = 56-88] and 92% [95%CI = 86-97] vs. 71% [95%CI = 57-84], respectively). Discrepancies between statistical results and conclusion occurred more frequently in articles written by authors from the private sector than from the public sector (42% [IC95% = 26-60] vs. 23% [IC95% = 18-26], P = 0.02). Industry affiliations of authors or industry support of studies are associated with the results of published studies on occupational cancer. The underlying mechanisms warrant further investigation. © 2015 Wiley Periodicals, Inc.

    Typically, adolescence is marked by cognitive and physical developments impacting on self-esteem, independence and sexual awareness, often resulting in increased appearance awareness and dissatisfaction. Adolescents with cancer have the additional burden of illness, treatments and resultant appearance changes. This study aimed to explore the impact of these changes on adolescents who have had cancer. In depth, semi-structured interviews were conducted with six females between 14 and 19 years who had completed treatment within the previous two years, and analysed using Interpretative Phenomenological Analysis (IPA). Concerns around an altered appearance were significant during treatment, serving as a constant reminder of 'difference' and a marker of illness. However, since treatment, participants expressed an apparent shift in views and expectations of their appearance, as well as the value placed on it -- expressing increased satisfaction with their own appearance and a decrease in its importance. While important to acknowledge the distress and challenges experienced by participants, results highlight the need for research and care to focus on positive experiences of patients, rather than simply maladjustment. Explanations for the findings are explored, including the temporary nature of many appearance changes and the life-threatening nature of cancer.

    Purpose: To examine the accuracy of clinical staging and its effects on outcome in bladder cancer (BC) patients treated with radical cystectomy (RC), using a large national database. Methods and Materials: A total of 16,953 patients with BC without distant metastases treated with RC from 1998 to 2009 were analyzed. Factors associated with clinical–pathologic stage discrepancy were assessed by multivariate generalized estimating equation models. Survival analysis was conducted for patients treated between 1998 and 2004 (n=7270) using the Kaplan-Meier method and Cox proportional hazards models. Results: At RC 41.9% of patients were upstaged, whereas 5.9% were downstaged. Upstaging was more common in females, the elderly, and in patients who underwent a more extensive lymphadenectomy. Downstaging was less common in patients treated at community centers, in the elderly, and in Hispanics. Receipt of preoperative chemotherapy was highly associated with downstaging. Five-year overall survival rates for patients with clinical stages 0, I, II, III, and IV were 67.2%, 62.9%, 50.4%, 36.9%, and 27.2%, respectively, whereas those for the same pathologic stages were 70.8%, 75.8%, 63.7%, 41.5%, and 24.7%, respectively. On multivariate analysis, upstaging was associated with increased 5-year mortality (hazard ratio [HR] 1.80, P<.001), but downstaging was not associated with survival (HR 0.88, P=.160). In contrast, more extensive lymphadenectomy was associated with decreased 5-year mortality (HR 0.76 for ≥10 lymph nodes examined, P<.001), as was treatment at an National Cancer Institute–designated cancer center (HR 0.90, P=.042). Conclusions: Clinical–pathologic stage discrepancy in BC patients is remarkably common across the United States. These findings should be considered when selecting patients for preoperative or nonoperative management strategies and when comparing the outcomes of bladder sparing approaches to RC.

    To evaluate the long-term results after breast-conserving surgery and radiation therapy in early breast cancer in terms of failure, survival, and cosmesis. One hundred fifty-four patients with stage I and II breast cancer were treated with conservative surgery plus radiotherapy between January 1992 and December 2002 at the Keimyung University Dongsan Medical Center. According to TNM stage, 93 patients were stage I, 50 were IIa, and 11 were IIb. The affected breasts were irradiated with 6 MV photons to 50.4 Gy in 28 fractions over 5.5 weeks with a boost irradiation dose of 10{approx}16 Gy to the excision site. Chemotherapy was administered in 75 patients and hormonal therapy in 92 patients with tamoxifen. Follow-up periods were 13{approx}179 months, with a median of 92.5 months. The 5- and 10-year overall survival rates were 97.3% and 94.5%, respectively. The 5- and 10-year disease-free survival (5YDFS and 10YDFS, respectively) rates were 92.5% and 88.9%, respectively; the ultimate 5YDFS and 10YDFS rates after salvage treatment were 93.9% and 90.2%, respectively. Based on multivariate analysis, only the interval between surgery and radiation therapy ({<=}6 weeks vs. >6 weeks, p=0.017) was a statistically significant prognostic factor for DFS. The major type of treatment failure was distant failure (78.5%) and the most common distant metastatic site was the lungs. The cosmetic results were good-to-excellent in 96 patients (80.7%). Conservative surgery and radiation for early stage invasive breast cancer yielded excellent survival and cosmetic results. Radiation therapy should be started as soon as possible after breast-conserving surgery in patients with early breast cancer, ideally within 6 weeks.

    ), whereas chi-square (χ²) statistic was conducted to evaluate the effects of training on the confidence level of students of both groups. Experimental and control groups demonstrated significant increased overall competency in otoscopy following the otoscopy training model with didactic and laboratory components. Posttest confidence ratings showed increases in all groups, and there were no significant differences between groups. The need for supplementary otoscopy training was warranted by low knowledge and clinical competency in otoscopy skills of audiology students as measured by pretest mean scores. After completing the training, both experimental and control groups showed significant improvement in knowledge and competency. Results also suggest that perceived confidence ratings may be misleading in determining students' clinical otoscopy skills. American Academy of Audiology.

    Intersphincteric resection has been performed as an alternative to abdominoperineal resection for low rectal cancer. The purpose of this study was to assess the long-term results after intersphincteric resection in terms of the morbidity, oncologic safety, and defecatory function. Between 1994 and 2006, 107 consecutive patients with low rectal cancer had curative intersphincteric resection, categorized as total, subtotal, or partial resection of the internal anal sphincter. There were no mortalities. Neorectal mucosal prolapse in patients with total intersphincteric resection and coloanal anastomotic stenosis in patients with subtotal or partial intersphincteric resection were observed as characteristic late complications. The five-year disease-free survival rates classified according to the TNM stage were 100 percent for stage I, 83.5 percent for stage II, and 72.0 percent for stage III cases. The five-year cumulative local recurrence rate after intersphincteric resection was 2.5 percent. Defecatory function, which was evaluated by bowel movement in a 24-hour period, and continence after intersphincteric resection were objectively good. The results of the multivariate analysis revealed that age was the only factor associated with a risk of fecal incontinence. Provided strict selection criteria are used, intersphincteric resection may be the optimal sphincter-preserving surgery for low rectal cancer.

    Objective:To analyze the clinical course and treatment result of lung metastases from breast cancer. Method:122 cases with lung metastases from breast cancer were treated with chemotherapy or chemotherapy plus endocrine therapy, response was assessed according to WHO criteria and survival rate estimated using the life Table. Results: The median time from initial treatment of primary tumor to lung metastases was 22 months. Sites of common consecutive metastases were lung, liver and bone. The overall response rate was 48% with a CR rate of 15%. Compared to non- DDP- encompassing regimen, the CR rate was higher in DDP-based chemotherapy (7%versus 21%, P<0.05) with a longer median survival time (MST). The PR rate was higher in regimens containing anthracycline (48%) than in those without anthracycline (20%, P<0.01). The response rate was similar between chemotherapy and chemotherapy plus endocrine therapy (P>0.05). No difference in MST was observed between patients receiving anthracycline-and non-anthracyclineencompassing regimens. The 1-, 3-, 5-, and 10-year survival rate was 77%, 22 %, 11%, and 10%, respectively.Conclusion: Size of primary tumor, the length of diseasefree interval, the number of lung metastases may provide additional information for predicting patients survival after treatment of lung metastases. Combination chemotherapy, especially DDP-based chemotherapy may prolong survival time of patients with lung metastases from breast cancer.

    Total laryngectomy (TL), with eventual postoperative radiotherapy, has proven to be effective in treating cases of locally advanced hypopharyngeal cancer. The aim of this study was to analyse the oncological outcomes of this procedure in patients with hypopharyngeal cancer classified T3 and T4. We studied 59 patients (33 T3 and 26 T4a) with primary squamous cell carcinoma of the hypopharynx treated with TL from 1998 to 2012. Mean age was 61 years with a male predominance (96.6%). All the patients were smokers and 96% consumed alcohol. Unilateral selective neck dissection (ND) was performed in 12 patients, unilateral radical ND in 11 patients, bilateral selective ND in 20 patients and radical ND plus selective ND in 14 patients. 66% of the patients received postoperative radiotherapy. Lymph node metastases occurred in 81% of the patients and extranodal invasion in 56% of them. 29% of the patients had loco-regional recurrence, 17% developed distant metastases, and 25% a second primary tumour. The 5-year disease-specific survival was 46%. TL extended to pharynx (with eventual postoperative radiotherapy) offers good oncological results in terms of loco-regional control and survival in locally advanced hypopharyngeal cancer, so organ preservation protocols should achieve similar oncological results to those shown by TL.

    2007-06-01

    Full Text Available Abstract Background Peroxisome proliferator-activated receptors (PPARs have emerged as important drug targets for diabetes. Drugs that activate PPARγ, such as the thiazolidinediones (TZDs, are widely used for treatment of Type 2 diabetes mellitus. PPARγ signaling could also play an anti-neoplastic role in several in vitro models, although conflicting results are reported from in vivo models. The effects of TZDs on cancer risk in humans needs to be resolved as these drugs are prescribed for long periods of time in patients with diabetes. Methods A total of 1003 subjects in community practice settings were interviewed at home at the time of enrolment into the Vermont Diabetes Information System, a clinical decision support program. Patients self-reported their personal and clinical characteristics, including any history of malignancy. Laboratory data were obtained directly from the clinical laboratory and current medications were obtained by direct observation of medication containers. We performed a cross-sectional analysis of the interviewed subjects to assess a possible association between cancer diagnosis and the use of TZDs. Results In a multivariate logistic regression model, a diagnosis of cancer was significantly associated with TZD use, even after correcting for potential confounders including other oral anti-diabetic agents (sulfonylureas and biguanides, age, glycosylated hemoglobin A1C, body mass index, cigarette smoking, high comorbidity, and number of prescription medications (odds ratio = 1.59, P = 0.04. This association was particularly strong among patients using rosiglitazone (OR = 1.89, P = 0.02, and among women (OR = 2.07, P = 0.01. Conclusion These data suggest an association between TZD use and cancer in patients with diabetes. Further studies are required to determine if this association is causal.

  2. The Reality in the Surveillance of Breast Cancer Survivors—Results of a Patient Survey

    2008-01-01

    Full Text Available Background: International guidelines for the surveillance of breast cancer patients recommend a minimized clinical follow-up including routine history and physical examination and regularly scheduled mammograms. However, the abandonment of scheduled follow-up examinations in breast cancer survivors remains a contradiction to established follow-up guidelines for other solid tumours.Patients and Methods: We report the patients’ view on the basis of a survey performed in two separate geographical areas in Germany. The questionnaires were sent out to 2.658 patients with a history of breast cancer.Results: A total of 801 patients (30.1% responded to the questionnaire. The results of the survey can be summarized in two major categories: First, necessity for surveillance was affi rmed by a majority (>95%, and 47.8% of the organized patients answered that there was a need for more intensive diagnostic effort during follow-up. The main expectation from an intensified follow-up was the increased feeling of security as expressed by >80% of the women. Second, the present survey indicates that most of the regularly scheduled follow-up visits were expanded using extensive laboratory and imaging procedures exceeding the quantity of examinations recommended in the present follow-up guidelines.Conclusion: Despite the fact that only one third of the patients responded to the questionnaire, the survey indicates that a majority of physicians who treated these patients still do not accept the present follow-up guidelines. To some extent this may be explained by the observation that patients and possibly also their doctors trust that intensified follow-up increases diagnostic security and survival. Since considerable changes in the treatment options of breast cancer have been made during the last decades a new trial of investigations in follow-up is warranted.

    Background Cachexia has a high prevalence in cancer patients and negatively impacts prognosis, quality of life (QOL), and tolerance/response to treatments. This study reports the results of three surveys designed to gain insights into cancer cachexia (CC) awareness, understanding, and treatment practices among health care professionals (HCPs). Methods Surveys were conducted globally among HCPs involved in CC management. Topics evaluated included definitions and synonyms of CC, diagnosis and treatment practices, and goals and desired improvements of CC treatment. Results In total, 742 HCPs from 14 different countries participated in the surveys. The majority (97%) of participants were medical oncologists or hematologists. CC was most frequently defined as weight loss (86%) and loss of appetite (46%). The terms loss of weight and decreased appetite (51% and 34%, respectively) were often provided as synonyms of CC. Almost half (46%) of the participants reported diagnosing CC and beginning treatment if a patient experienced a weight loss of 10%. However, 48% of the participants would wait until weight loss was ≥15% to diagnose CC and start treatment. HCPs also reported that 61%–77% of cancer patients do not receive any prescription medication for CC before Stage IV of disease is reached. Ability to promote weight gain was rated as the most important factor for selecting CC treatment. Key goals of treatment included ensuring that patients can cope with the cancer and treatment and have a QOL benefit. HCPs expressed desire for treatments with a more CC-specific mode of action and therapies that enhance QOL. Conclusions These surveys underscore the need for increased awareness among HCPs of CC and its management. PMID:28007753

  4. Biosemiotic Entropy of the Genome: Mutations and Epigenetic Imbalances Resulting in Cancer

    Directory of Open Access Journals (Sweden)

    Samuel S. Shepard

    2013-01-01

    Full Text Available Biosemiotic entropy involves the deterioration of biological sign systems. The genome is a coded sign system that is connected to phenotypic outputs through the interpretive functions of the tRNA/ribosome machinery. This symbolic sign system (semiosis at the core of all biology has been termed “biosemiosis”. Layers of biosemiosis and cellular information management are analogous in varying degrees to the semiotics of computer programming, spoken, and written human languages. Biosemiotic entropy — an error or deviation from a healthy state — results from errors in copying functional information (mutations and errors in the appropriate context or quantity of gene expression (epigenetic imbalance. The concept of biosemiotic entropy is a deeply imbedded assumption in the study of cancer biology. Cells have a homeostatic, preprogrammed, ideal or healthy state that is rooted in genomics, strictly orchestrated by epigenetic regulation, and maintained by DNA repair mechanisms. Cancer is an eminent illustration of biosemiotic entropy, in which the corrosion of genetic information via substitutions, deletions, insertions, fusions, and aberrant regulation results in malignant phenotypes. However, little attention has been given to explicitly outlining the paradigm of biosemiotic entropy in the context of cancer. Herein we distill semiotic theory (from the familiar and well understood spheres of human language and computer code to draw analogies useful for understanding the operation of biological semiosis at the genetic level. We propose that the myriad checkpoints, error correcting mechanisms, and immunities are all systems whose primary role is to defend against the constant pressure of biosemiotic entropy, which malignancy must shut down in order to achieve advanced stages. In lieu of the narrower tumor suppressor/oncogene model, characterization of oncogenesis into the biosemiotic framework of sign, index, or object entropy may allow for more

    Full Text Available Background Today, with improvements in laparoscopy technique, surgery of rectal cancer is performed by laparoscopy. Objectives This study was performed to evaluate oncologic results of open versus laparoscopic surgery of rectal cancer in terms of resection margins, removal of lymph nodes and recurrence rate. Patients and Methods This descriptive-analytic study was performed on 88 patients with middle and lower rectal cancer in the two equivalent groups of laparoscopic and open surgery in Mashhad Ghaem and Omid hospitals during 2011 - 2013. Information including age, sex, number of removed and involved lymph nodes, proximal, distal, and radial margins, tumor stage and location, recurrence and disease-free survival collected in the questionnaire and analyzed using descriptive statistics and frequency distribution tables and t-test. Results Both groups of open and laparoscopic surgery had similar characteristics of age, sex, recurrence and disease-free survival, tumor margins and one-year mortality. The number of removed and involved lymph nodes was higher in the laparoscopic group (5.16 vs. 3.55, respectively, with P < 0.050, and 1.74 vs. 0.59 with P = 0.023, but the ratio of involved lymph nodes to the total number of removed lymph nodes was not different between the two groups (LNR (P = 0.071. Tumor stage was higher in the laparoscopic group and most were in stages II and III (P < 0.001. Conclusions Laparoscopic surgery is an effective technique for safe margin and removing lymph nodes in rectal cancer.

    Full Text Available Objectives. Existing findings on cancer patients' use of information sources were synthesized to 1 rank the most and least used information sources and the most helpful information sources and to 2 find the impact of patient demographics and situations on use of information sources. Method. . To synthesize results found across studies, a systematic review was conducted. Medline and CINAHL were searched to retrieve literature on cancer patients' information source use. The retrieved articles were carefully selected according to predetermined criteria, and several articles were eliminated in a systematic approach. Analysis. The twelve articles that met the criteria were systematically analysed by extracting data from articles and summarizing data for the purpose of synthesis to determine the meaning of findings on most used information sources, least used information sources, most helpful information sources, effect of patient characteristics on preference for an information source, and effect of patient situations on preference for an information source. Results. In descending order of use, health care professionals, medical pamphlets, and family and friends were most used information sources. Internet and support groups were least used. In descending order of helpfulness, books, health care professionals and medical pamphlets were found to be most helpful information sources. Younger patients used health care professionals and certain forms of written information sources more than older patients. Conclusion. . The systematic review shows that many areas of cancer patients' information source use have been either neglected or barely analysed. An in-depth understanding of cancer patients' use of information sources and the characteristics in information sources they consider to be helpful is important for developing successful interventions to better inform patients.

Our study found that men with prevalent diabetes (pre-prostate cancer diagnosis) generally had the poorest general HRQL, urinary control and sexual function scores over time, independent of treatment. Non-diabetic men had the best scores and men with incident diabetes (post-prostate cancer diagnosis) reported intermediate scores. OBJECTIVE • To investigate the association between prostate cancer, diabetes, and long-term general and cancer-specific health-related quality of life (HRQL) in a cohort of men with non-metastatic prostate cancer. PATIENTS AND METHODS • We used data from self-administered surveys to assess the HRQL of men with localized or locally advanced disease at 6 (baseline), 12, 24, and 60 months after initial diagnosis. • We examined changes in general and cancer-specific HRQL with repeated measures analyses using a mixed-model approach. RESULTS • In total, we evaluated 1811 men, including 13% with prevalent (pre-prostate cancer diagnosis) diabetes, 12% with incident (post-prostate cancer diagnosis) diabetes, and 75% who never reported being diagnosed with diabetes. • Generally, men with prevalent diabetes had the poorest scores on general HRQL and non-diabetic men the best scores, independent of treatment. • Similarly, men with prevalent diabetes had the lowest urinary control and sexual function scores over time, while men without diabetes had the highest scores. Men with incident diabetes reported intermediate scores. CONCLUSION • Prostate cancer survivors with comorbid diabetes have poorer general and cancer-specific HRQL than those without diabetes.

    Supplementary feeding of garden birds generally has benefits for both bird populations and human wellbeing. Birds have excellent colour vision, and show preferences for food items of particular colours, but research into colour preferences associated with artificial feeders is limited to hummingbirds. Here, we investigated the colour preferences of common UK garden birds foraging at seed-dispensing artificial feeders containing identical food. We presented birds simultaneously with an array of eight differently coloured feeders, and recorded the number of visits made to each colour over 370 30-minute observation periods in the winter of 2014/15. In addition, we surveyed visitors to a garden centre and science festival to determine the colour preferences of likely purchasers of seed feeders. Our results suggest that silver and green feeders were visited by higher numbers of individuals of several common garden bird species, while red and yellow feeders received fewer visits. In contrast, people preferred red, yellow, blue and green feeders. We suggest that green feeders may be simultaneously marketable and attractive to foraging birds.

    Neuro-imaging methods for detecting functional and structural inter-regional connectivity are in a rapid phase of development. While reports of regional connectivity patterns based on individual methods are becoming common, studies comparing the results of two or more connectivity-mapping methods remain rare. In this study, we applied transcranial magnetic stimulation during PET imaging (TMS/PET), a stimulation-based method, and meta-analytic connectivity modeling (MACM), a task-based method to map the connectivity patterns of the supplementary motor area (SMA). Further, we drew upon the behavioral domain meta-data of the BrainMap® database to characterize the behavioral domain specificity of two maps. Both MACM and TMS/PET detected multi-synaptic connectivity patterns, with the MACM-detected connections being more extensive. Both MACM and TMS/PET detected connections belonging to multiple behavioral domains, including action, cognition and perception. Finally, we show that the two connectivity-mapping methods are complementary in that, the MACM informed on the functional nature of SMA connections, while TMS/PET identified brain areas electrophysiologically connected with the SMA. Thus, we demonstrate that integrating multimodal database and imaging techniques can derive comprehensive connectivity maps of brain areas.

    Diet containing the anthelminthic fenbendazole is used often to treat rodent pinworm infections because it is easy to use and has few reported adverse effects on research. However, during fenbendazole treatment at our institution, an established human lymphoma xenograft model in C.B-17/Icr-prkdcscid/Crl (SCID) mice failed to grow. Further investigation revealed that the fenbendazole had been incorporated into a sterilizable diet supplemented with additional vitamins to compensate for loss during autoclaving, but the diet had not been autoclaved. To assess the role of fenbendazole and supplementary vitamins on tumor suppression, 20 vendor-supplied 4-wk-old SCID mice were assigned to 4 treatment groups: standard diet, diet plus fenbendazole, diet plus vitamins, and diet plus both vitamins and fenbendazole. Diet treatment was initiated 2 wk before subcutaneous flank implantation with 3 x 107 lymphoma cells. Tumor size was measured by caliper at 4-d intervals until the largest tumors reached a calculated volume of 1500 mm3. Neither diet supplemented with vitamins alone nor fenbendazole alone caused altered tumor growth as compared with that of controls. However, the group supplemented with both vitamins and fenbendazole exhibited significant inhibition of tumor growth. The mechanism for this synergy is unknown and deserves further investigation. Fenbendazole should be used with caution during tumor studies because it may interact with other treatments and confound research results.

    During the course of updating the K-Reactor Safety Analysis Report Chapter 15 in 1990, it was identified that the current Supplementary Safety System (SSS) may not be adequate in protecting the reactor during the process water pump coastdown initiated by a loss of AC power when the safety rods are assumed to fail. A SSS modification project was initiated to add an additional ink injection pathway near the pump suction. In addition, the Department of Energy raised a question on the thermal buoyancy effects on moderator flow pattern and ink dispersion in the moderator space. The development and documentation of a two-dimensional code called MODFLOW was undertaken to describe the problem. This report discusses the results of the moderator flow and ink (Gadolinium Poison Solution - GPS) dispersion tests designed to provide qualified data for validation and benchmarking of the MODFLOW computer code with the secondary objectives being the development of concentration profiles and video footage of simulated GPS dispersion under steady-state and transient flow conditions.

    The Korean Breast Cancer Society (KBCS) has reported a nationwide breast cancer data since 1996. We present a comprehensive report on the facts and trends of breast cancer in Korea in 2013. Data on the newly diagnosed patients in the year 2013 were collected from 99 hospitals by using nationwide questionnaire survey. Clinical characteristics such as stage of cancer, histologic types, biological markers, and surgical management were obtained from the online registry database. A total of 19,316 patients were newly diagnosed with breast cancer in 2013. The crude incidence rate of female breast cancer including carcinoma in situ was 76.2 cases per 100,000 women. The median age at diagnosis was 50 years, and the proportions of postmenopausal women with breast cancer accounted for more than half of total patients. The proportion of early breast cancer increased consistently, and the pathologic features have changed accordingly. Breast-conserving surgery was performed in more cases than total mastectomy in the year. The total number of breast reconstruction surgeries markedly increased approaching 3-fold in last 11 years. According to annual percentile change of invasive cancer incidence, the incidence increased rapidly until 2010. And thereafter the increase of it became steadier. For ductal carcinoma in situ, the incidence consistently increased during the same period without any joinpoint. Analysis of nationwide registry data will contribute to defining of the trends and characteristics of breast cancer in Korea.

    The provision of study results to research participants is supported by pediatric and adult literature. This study assessed adult cancer patient preferences surrounding aggregate result disclosure to study participants. A 46-item questionnaire was given to 250 adult cancer patients who had participated in oncology trials at a single center. Respondents answered questions surrounding their preferences for timing, content, and modality of communication for dissemination of study results. Questionnaire completion rate was 76% (189/250). Most patients (92%) strongly felt a right to know study results. Patients preferred result dissemination via letter for trials with positive outcomes, but preferred in-person clinic visits for negative outcomes. Despite this, a majority of participants (59%) found letters acceptable to inform participants of negative results. Only a minority (36%) of the participants found Internet-based disclosure acceptable for negative trial results. Unfortunately, very few patients (8%) recalled having received the results for a study they participated in, and of these patients, less than half fully understood the results they were given. Most clinical trial participants feel they have a right to study result disclosure, regardless of trial outcome. In-person visits are preferred for negative results, but more feasible alternatives such as letters were still acceptable for the majority of participants. However, Internet-based disclosure was not acceptable to most participants in oncology trials. Time and cost allocations for result disclosure should be considered during grant and ethics board applications, and clear guidelines are required to help researchers share the results with patients. © The Author(s) 2016.

    MicroRNAs (miRNAs) are small [∼21 nucleotide (nt)] non coding RNAs (ncRNAs) that regulate gene expression posttranscriptionally. About 3.0% of human genes encode for miRNAs, and up to 30.0% of human protein coding genes may be regulated by miRNAs. Currently, more than 2000 unique human mature microRNAs are known. MicroRNAs play a key role in diverse biological processes including development, cell proliferation, differentiation and apoptosis. These processes are commonly dysregulated in cancer, implicating miRNAs in carcinogenesis, where they act as tumor supressors or oncogenes. Several miRNAs are associated with breast cancer. Here we present our initial results of miRNA analyses of breast cancer tissues using quantitative real time-polymerase chain reaction (ReTi-PCR) (qPCR) involving stem-loop reverse transcriptase (RT) primers combined with TaqMan® PCR and miRNA microarray analysis.

    This paper presents results from a case-control study carried out in the county of Mataro, Spain. The study was designed to investigate the possible causes of an unusually high mortality rate from bladder cancer in Mataro county as compared to Spain as a whole, and this report focuses on occupational exposures. The study is based on 57 cases who were hospitalized for or died from bladder cancer between 1978 and 1981. Two controls per case were matched for sex, age, residence, and date of either hospitalization or death. Information was collected on smoking, coffee drinking, and occupation. Occupational histories were then evaluated and coded blind by a group of occupational health physicians. Analyses were carried out by means of conditional logistic regression. Among a group of common occupational sectors, an increased risk for past employment in the textile industry (OR = 2.2; p = .038) was found. Further analyses indicated that the risk is particularly elevated (OR = 4.41; 95% confidence limits; 1.15-16.84) for subjects who worked in dyeing or printing and who were most probably exposed to azo-dyes. Exposure in the textile industry may be responsible for 16% of the bladder cancers in the Mataro area. A list of dyes commonly used in the Mataro textile industries was compiled and cross-checked with lists of substances tested or evaluated for carcinogenesis.

    Studies of radon-exposed underground miners predict that residential radon is the second leading cause of lung cancer mortality; however, case-control studies of residential radon have not provided unambiguous evidence of an association. Owing to small expected risks from residential radon and uncertainties in dosimetry, large studies or pooling of multiple studies are needed to fully evaluate effects. We pooled data from 2 case-control studies of residential radon representing 2 large radon studies conducted in China. The studies included 1,050 lung cancer cases and 1,996 controls. In the pooled data, odds ratios (OR) increased significantly with greater radon concentration. Based on a linear model, the OR with 95% confidence intervals (CI) at 100 Becquerel/cubic-meter (Bq/m{sup 3}) was 1.13 (1.01, 1.36). For subjects resident in the current home for 30 years or more, the OR at 100 Bq/m{sup 3} was 1.32 (1.07, 1.91). Results across studies were consistent with homogeneity. Estimates of ORs were similar to extrapolations from miner data and consistent with published residential radon studies in North American and Europe, suggesting long-term radon exposure at concentrations found in many homes increases lung cancer risk.

    Full Text Available Aims, results, advantages and possible disadvantages of preoperative chemotherapy (pCHT for breast cancer are discussed in this review. Established chemotherapeutic regimens are described with respect to new drugs that are added to combinations now and in the future. Illustrating the potential of new components, trastuzumab and cytotoxic chemotherapy, were combined in neoadjuvant trials for the first time. This approach yielded impressing and unprecedented high pathological response rates. An overview regarding current neoadjuvant cytostatic and immunotherapy trials is given. Established prognostic factors like axillary lymph-nodal status are altered during pCHT, which causes the need for new prognostic markers. The consequences of these changes for clinical decision making are demonstrated. It seems possible that the advances of gene array and protein expression profile technologies will lead to improved prognostic and predictive statements. Tumor tissue can be analyzed before during and after treatment in this regard recent studies investigating the response to specific, chemotherapeutics in correlation to molecular markers are reviewed. These approaches might enable us to identify chemoresistance of specific tumors. Furthermore pCHT allows testing of chemosensitivity in vivo in an early stage, which might lead to a more individualized cancer therapy. We discuss radiotherapy after neoadjuvant therapy and the risk of local relapse after breast conserving surgery, which was made feasible by pCHT. It is shown how the evaluation of efficacy of new cancer drugs, using the neoadjuvant situation, can be done more rapidly than in the metastatic and adjuvant setting.

    To evaluate the initial results of the oesophagogastric cancer registry developed for the Sociedad Valenciana de Cirugía and the Health Department of the Comunidad Valenciana (Spain). Fourteen of the 24 public hospitals belonging to the Comunidad Valenciana participated. All patients with diagnosis of oesophageal or gastric carcinomas operated from January 2013 to December 2014 were evaluated. Demographic, clinical and pathological data were analysed. Four hundred and thirty-four patients (120 oesophageal carcinomas and 314 gastric carcinomas) were included. Only two hospitals operated more than 10 patients with oesophageal cancer per year. Transthoracic oesophaguectomy was the most frequent approach (84.2%) in tumours localized within the oesophagus. A total gastrectomy was performed in 50.9% patients with gastroesophageal junction (GOJ) carcinomas. Postoperative 30-day and 90-day mortality were 8% and 11.6% in oesophageal carcinoma and 5.9 and 8.6% in gastric carcinoma. Before surgery, middle oesophagus carcinomas were treated mostly (76,5%) with chemoradiotherapy. On the contrary, lower oesophagus and GOJ carcinomas were treated preferably with chemotherapy alone (45.5 and 53.4%). Any neoadjuvant treatment was administered to 73.6% of gastric cancer patients. Half patients with oesophageal carcinoma or gastric carcinoma received no adjuvant treatment. This registry revealed that half patients with oesophageal cancer were operated in hospitals with less than 10 cases per year at the Comunidad Valenciana. Also, it detected capacity improvement for some clinical outcomes of oesophageal and gastric carcinomas. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    Retrospective data indicate that immunoprofiling of T cell markers can be prognostic in colon cancer. Prospective T cell immunoprofiling of colon cancer has not been well defined for patients whose lymph nodes are ultrastaged. A prospective cohort was selected from patients enrolled in an ongoing phase II multicenter trial of nodal ultrastaging for colon cancer. Primary tumor specimens from 89 patients were analyzed by immunohistochemistry for the T cells CD3(+), CD4(+), CD8(+), and FOXP3(+). Lymphocyte populations were quantified with digital image analysis. Results were examined for their association with 5-year disease-free survival along with TNM stage and clinicopathologic variables. Longer disease-free survival was associated with higher CD3(+) counts at the invasive margin (IM) (p = 0.005), higher CD8(+) counts at the tumor center (TC) and IM (p = 0.002), a lower CD4(+)/CD8(+) ratio at the TC+IM (p = 0.027), and a higher CD8(+)/FOXP3(+) ratio at the TC+IM (p = 0.020). After multivariable analysis, CD8(+) at the TC+IM (p = 0.002), the CD8(+)/FOXP3(+) ratio at the TC+IM (p = 0.004), and the number of tumor-positive lymph nodes (p = 0.003) remained significant. This is the first prospective demonstration of the prognostic utility of immunoprofiling in colon cancer after nodal ultrastaging. Staging based on tumor immunoprofile can augment TNM staging and provide targets for specific immunotherapies. Copyright © 2016. Published by Elsevier Inc.

    The indications for a pancreatectomy with a partial resection of the portal or superior mesenteric vein for pancreatic cancer, when the vein is involved by the tumor, remain controversial. It can be assumed that when such involvement is not extensive, resection of the tumor and the involved venous segment, followed by venous reconstruction will extend the potential benefits of this resection to a larger number of patients. The further hypothesis of this study is that whenever involvement of the vein by the tumor does not exceed 2 cm in length, this involvement is more likely due to the location of the tumor being close to the vein rather than because of its aggressive biological behavior. Consequently, in these instances a pancreatectomy with a resection of the involved segment of portal or superior mesenteric vein for pancreatic cancer is indicated, as it will yield results that are superposable to those of a pancreatectomy for cancer without vascular involvement. Twenty-nine patients with carcinoma of the pancreas involving the portal or superior mesenteric vein over a length of 2 cm or less underwent a macroscopically curative resection of the pancreas en bloc with the involved segment of the vein. The venous reconstruction procedures included a tangential resection/lateral suture in 15 cases, a resection/end-to-end anastomosis in 11, and a resection/patch closure in 3. Postoperative mortality was 3.4%; morbidity was 21%. Local recurrence was 14%. Cumulative (standard error) survival rate was 17% (9%) at 3 years. A pancreatectomy combined with a resection of the portal or superior mesenteric vein for cancer with venous involvement not exceeding 2 cm is indicated in order to extend the potential benefits of a curative resection.

    According to the World Health Organization, breast cancer is the most common cancer among women worldwide, claiming the lives of hundreds of thousands of women each year. Near infrared diffuse optical tomography (DOT) has demonstrated a great potential as an adjunct modality for differentiation of malignant and benign breast lesions and for monitoring treatment response of patients with locally advanced breast cancers. The path toward commercialization of DOT techniques depends upon the improvement of robustness and user-friendliness of this technique in hardware and software. In the past, our group have developed three frequency domain prototype systems which were used in several clinical studies. In this study, we introduce our newly under development US-guided DOT system which is being improved in terms of size, robustness and user friendliness by several custom electronic and mechanical design. A new and robust probe designed to reduce preparation time in clinical process. The processing procedure, data selection and user interface software also updated. With all these improvements, our new system is more robust and accurate which is one step closer to commercialization and wide use of this technology in clinical settings. This system is aimed to be used by minimally trained user in the clinical settings with robust performance. The system performance has been tested in the phantom experiment and initial results are demonstrated in this study. We are currently working on finalizing this system and do further testing to validate the performance of this system. We are aiming toward use of this system in clinical setting for patients with breast cancer.

    When testing for prostate cancer, as many as 75% of men with a raised prostate-specific antigen (PSA) have a benign biopsy result. Little is known about the psychological effect of this result for these men. In all, 330 men participating in the prostate testing for cancer and treatment (ProtecT) study were studied; aged 50-69 years with a PSA level of > or = 3 ng ml(-1) and a negative biopsy result. Distress and negative mood were measured at four time-points: two during diagnostic testing and two after a negative biopsy result. The majority of men were not greatly affected by testing or a negative biopsy result. The impact on psychological health was highest at the time of the biopsy, with around 20% reporting high distress (33 out of 171) and tense/anxious moods (35 out of 180). Longitudinal analysis on 195 men showed a significant increase in distress at the time of the biopsy compared with levels at the PSA test (difference in Impact of Events Scale (IES) score: 9.47; 95% confidence interval (CI) (6.97, 12.12); Presult (difference in score: 7.32; 95% CI (5.51, 9.52); Presult. Men should be informed of the risk of distress relating to diagnostic uncertainty before they consent to PSA testing.

    Full Text Available The main objective of this research is to investigate efficiency of use of supplementary video content in multimedia teaching. Integrating video clips in multimedia lecture presentations may increase students’ perception of important information and motivation for learning. Because of that, students can better understand and remember key points of a lecture. Those improvements represent some important learning outcomes. This research showed that segmentation of teaching materials with supplementary video clips may improve lecture organization and presentation in order to achieve effective teaching and learning. The context of the video content and the position of supplementary video clips in teaching material are important influences on factors for motivation and efficiency of learning. This research presents the effects of the use of supplementary videos with different context of content (entertainment and educational as well as the effects of their position within the teaching material. The experimental results showed that the most efficient method of use of supplementary video is integration with educational video content in the middle of a lecture. This position of video insertion provides the best results. The context of video content influences efficiency of learning also. Entertainment video was not as efficient as educational, but it can be used to engage and motivate students for learning. The given results have been confirmed with a subjective assessment of students’ quality of experience with different methods of embedding video clips.

    Endometrial cancer patients with high grade tumours, deep myometrial invasion or advanced stage disease have a poor prognosis. Randomised studies have demonstrated the prevention of loco-regional relapses with radiotherapy (RT) with no effect on overall survival (OS). The possible additive effect of chemotherapy (CT) remains unclear. Two randomised clinical trials (NSGO-EC-9501/EORTC-55991 and MaNGO ILIADE-III) were undertaken to clarify if sequential combination of chemotherapy and radiotherapy improves progression-free survival (PFS) in high-risk endometrial cancer. The two studies were pooled. Patients (n=540; 534 evaluable) with operated endometrial cancer International Federation of Obstetrics and Gynaecology (FIGO) stage I-III with no residual tumour and prognostic factors implying high-risk were randomly allocated to adjuvant radiotherapy with or without sequential chemotherapy. In the NSGO/EORTC study, the combined modality treatment was associated with 36% reduction in the risk for relapse or death (hazard ratio (HR) 0.64, 95%confidence interval (CI) 0.41-0.99; P=0.04); two-sided tests were used. The result from the Gynaecologic Oncology group at the Mario Negri Institute (MaNGO)-study pointed in the same direction (HR 0.61), but was not significant. In the combined analysis, the estimate of risk for relapse or death was similar but with narrower confidence limits (HR 0.63, CI 0.44-0.89; P=0.009). Neither study showed significant differences in the overall survival. In the combined analysis, overall survival approached statistical significance (HR 0.69, CI 0.46-1.03; P=0.07) and cancer-specific survival (CSS) was significant (HR 0.55, CI 0.35-0.88; P=0.01). Addition of adjuvant chemotherapy to radiation improves progression-free survival in operated endometrial cancer patients with no residual tumour and a high-risk profile. A remaining question for future studies is if addition of radiotherapy to chemotherapy improves the results. Copyright 2010 Elsevier

    Full Text Available Abstract Background Informal caregiving is increasingly common as the U.S. population ages, and there is concern that caregivers are less likely than non-caregivers to practice health-promoting behaviors, including cancer screening. We examined caregiving effects on cancer risk behaviors and breast and cervical cancer screening in the 2009 Behavioral Risk Factor Surveillance System. Methods Women age ≥41 with data on breast and cervical cancer screening were included (weighted frequency 3,478,000 women. Cancer screening was classified according to American Cancer Society guidelines. We evaluated the association of caregiving with cancer risk behaviors (obesity, physical activity, alcohol intake, smoking status, and fruit/vegetable consumption and cancer screening (mammography, clinical breast exam [CBE], and Pap test using logistic regression overall and with stratification on age ( Results Caregivers had greater odds of being obese, physically active, and current smokers. Subgroup analyses revealed that caregiving was associated with obesity in younger women and whites, and with less obesity in older women. Also, caregiving was associated with smoking only among younger women and non-whites. Caregivers had greater odds of ever having had a mammogram or CBE, yet there was no association with mammogram, CBE, or Pap test within guidelines. Conclusions Caregiving was associated with some health behaviors that increase cancer risk, yet not with cancer screening within guidelines. Effects of caregiving by age and race require confirmation by additional studies.

    Physical activity (PA) has been associated with lower risk of cardiovascular diseases, but the evidence linking PA with lower cancer risk is inconclusive. We examined the independent and interactive effects of PA and obesity using body mass index (BMI) as a proxy for obesity, on the risk of developing prostate (PC), postmenopausal breast (BC), colorectal (CRC), ovarian (OC) and uterine (UC) cancers. We estimated odds ratios (OR) and 95% confidence intervals (CI), adjusting for cancer specific confounders, in 6831 self-reported cancer cases and 1992 self-reported cancer-free controls from the Cancer Lifestyle and Evaluation of Risk Study, using unconditional logistic regression. For women, BMI was positively associated with UC risk; specifically, obese women (BMI≥30kg/m(2)) had nearly twice the risk of developing UC compared to women with healthy-BMI-range (cancer type, CRC and PC. In particular, obese men had 37% (OR=1.37;CI:1.11-1.70), 113% (OR=2.13;CI:1.55-2.91) and 51% (OR=1.51;CI:1.17-1.94) higher risks of developing any cancer, CRC and PC respectively, when compared to men with healthy-BMI-range (BMIcancer risks for men. We found no evidence of an interaction between BMI and PA in the CLEAR study. These findings suggest that PA and obesity are independent cancer risk factors. Copyright © 2017 Elsevier Ltd.

    Although the role of an axillary lymph node dissection for the primary breast cancer is considered to be a prognostic indicator, regarding the determination of the treatment strategy after surgery, and the best modality for regional control, this procedure is harmful rather than ineffective in cases with a histologically negative node. The sentinel lymph node (SLN) biopsy is a procedure used to assess the degree of nodal involvement before and/or during surgery. From June, 1999 to January, 2002, we performed an SLN biopsy for 47 primary breast cancer patients (T1-2N0-1M0) using either a dye or combined (dye and gamma probe guided) method with a back up conventional axillary node dissection at the Second Department of Surgery, Fukuoka University School of Medicine. The dye method was performed on 39 patients, and it resulted in the accurate identification of the SLN in 74.4% of patients, compared with 94.7% in latter series of 19 patients. In addition, the dye method demonstrated a sensitivity of 66.6%, a specificity of 100% and an accuracy of 96.6%. Eight patients received the combined method, and the SLN was identified in 100% of these patients. This combined method showed a sensitivity of 80%, a specificity of 100% and an accuracy of 87.5%. On the other hand an intraoperative examination using frozen sections resulted in a sensitivity of 50%, a specificity of 100% and an accuracy in the diagnosis of 83.3%. These data suggest that an SLN biopsy for early breast cancer (T1N0) can be performed to eliminate any unnecessary axillary node dissection in cases with negative SLN. However, the successful results of this method depend on the cooperation of the multidisciplinary team (surgeons, pathologists and nuclear radiologists) and the informed consent of all patients.

    Several prognostic histological features have been established in female breast cancer (BC), but it is unknown whether these can be extrapolated to male BC patients. The aim of this study was to evaluate the prognostic value of several histological features in a large series of male BC. Central pathology review was performed for 1483 male BCs collected through part 1 of the European Organisation for Research and Treatment of Cancer (EORTC) International Male BC Program. Pathology review included histological subtype, grade, mitotic activity index (MAI), presence of a fibrotic focus and density of tumour-infiltrating lymphocytes (TILs). These features were correlated with clinical outcome. The relationship between these features and surrogate molecular subtypes using immunohistochemistry was also assessed. Median follow-up for overall survival (OS) was 7.1 years. Overall histological grade was not significantly associated with OS (p = 0.129). MAI, the presence of a fibrotic focus and a low TIL density however were correlated with unfavourable OS (p = 0.023, p = 0.004 and p = 0.011, respectively). BC subtype correlated with TIL density (p = 0.015), as we observed a higher density for human epidermal growth factor receptor type 2 (HER2) positive BC compared to luminal HER2-negative subtype. No association was observed between subtype and fibrotic focus. Histologic grade was not significantly correlated with clinical outcome in this series, unlike what is seen in female patients. These results contribute to our understanding of male BC and indicate the importance of further research on the optimisation of risk stratification and treatment decisions for male BC patients.

    Full Text Available The world marked increase in the incidence of cervical cancer in young women, especially from 29 to 45 years old. Analysis showed that in patients with preserved ovarian function, not only the effectiveness of the treatment, but also the quality of life. It is associated with the acceleration, earlier puberty and the onset of sexual activity. In recent years more and more widely used radical surgery with preservation of the ovaries and the abduction of the radiation castration and preservation of reproductive function. In the National Cancer Research Centre of the Ministry of Health of the Republic of Uzbekistan analyzed the results of surgical treatment of 204 patients with cervical cancer younger.

    Radiotherapy is frequently applied to esophageal squamous cell carcinoma (ESCC), because about 90 percent of the cases is diagnosed in its late stages , although the 5-year survival rate after radiotherapy alone ranges from only 6 to 11.6 percent. Stage I ESCC has been considered a good target for radiation therapy, but the 5-year overall survival ratio is only 62 percent. It is well known that the cells in cancer tissue are heterogeneous in morphology and differentiation, even if the tissue consists of progenies developed from a single neoplastic cell. Cultured cancer cells have often been characterized by their morphological heterogeneity. When we assessed the dose-survival responses of 31 culture d human ESCC cell lines in a colony-formation assay, we found that one cell line (KYSE70) formed morphologically variable colonies in one dish. These were a densely mounding type (M-type), a flat, diffusive type (F-type), and a type with mixed mounding and flat cells (M/F-type). The M- and F-type colonies were isolated from a clone of the KYSE70 cells, and both types of cells produced tumors in nude mice. Interestingly, metastatic tumors were observed in mice transplanted with the F-type-colony forming cells. X-ray irradiation stimulated the cells to transform from M-type to F-type. A direct comparison of gene expression levels between both types of cells was conducted using an oligonucleotide micro-array. Genes involved in tumor invasion, cell motility, and cell-shape change were up-regulated in F-type colony-forming cells. Our data suggest that the cancer stem-like cells exist in the M-type colony-forming cells, and that X-ray irradiation stimulated them to de-differentiate into more malignant progenies than the parental cells. Our study suggests that it is urgent to establish methods to ascertain whether or not tumor tissues contain cancer stem cells. If tissues do contain cancer stem cells, excluding or killing them before radiotherapy or chemotherapy may greatly

    Eighteen patients with 25 unresectable advanced or recurrent head and neck cancers (squamous cell carcinomas) received thermochemotherapy in combination with radiotherapy. The total radiation dose ranged from 50 to 82 Gy (mean, 65.6 Gy). Patients received thermochemotherapy twice a week, for a total number of 8.8 sessions, on average. The temperature in the tumor, as a result of the hyperthermia, was over 42 deg C in 185 (84.5%) of the 219 treatments. Three kinds of heating systems were used: a 13.56-MHz radiofrequency system, a 2450-MHz microwave system, and a radiofrequency interstitial system. The total amount of administered CDDP ranged from 40 to 300 mg (mean, 110 mg), combined with PEP and/or 5FU. Background factors (tumor factors and treatment factors) were investigated in detail, and the clinical results (tumor response and the 5-year cumulative focal control rate) were evaluated. The relationship between these two results was then analyzed using univariate and multivariate statistics. The clinical results of patients with a WHO histological classification of grade 3 were poor compared with patients with a classification of grade 1 or 2. The difference between these two results was significant when analyzed using univariate statistics, but not significant when analyzed using multivariate statistics. The clinical results of patients with primary lesions surrounded by bony tissues were slightly poor compared with those of patients whose lesions were surrounded by soft tissues, but the difference between these two results was not significant. Successful treatment of refractory recurrent tumors, large tumor masses, and diffuse invasive carcinomas was not affected by the treatment factors (heating systems, heating sessions, radiation dose, and CDDP dose and drug combination). These results suggest that refractory recurrence, proximity to bony tissues, tumor size, and histological malignancy might not be prognostic variables for thermochemoradiotherapy strategy

    The aim of the present study was to review the National Colorectal Cancer Screening Program (the Program) in Lithuania according to the criteria set by the European Union. In Lithuania, screening services are provided free of charge to the population. The National Health Insurance Fund (NHIF) reimburses the institutions for performing each service; each procedure within the Program has its own administrative code. All the information about the performance of the Program is collected in one institution - the NHIF. The results of the Program were retrieved from the database of NHIF from the start of the Program from 1 July 2009 to 1 July 2012. Descriptive analysis of epidemiological indicators was carried out. Results were compared with the references in the guidelines of the European Union for quality assurance in colorectal cancer (CRC) screening and diagnosis. Information service [which involves fecal immunochemical test (FIT)] was provided to 271,396 of 890,309 50-74-year-old residents. The screening uptake was 46.0% over 3 years. During this period, 19,455 (7.2%) FITs were positive and 251,941 (92.8%) FITs were negative. Referral for colonoscopy was performed in 10,190 (52.4%) patients. Colonoscopy was performed in 12,864 (66.1%) patients. Colonoscopy did not indicate any pathological findings in 8613 (67.0%) patients. Biopsies were performed in 4251 (33.0%) patients. The rate of high-grade neoplasia reported by pathologists was 3.9%; the rate of cancer was 3.1% of all colonoscopies. The rate of CRC detected by the Program was 0.2%. The CRC screening program in Lithuania meets most of the requirements for standardized CRC screening programs. The invitation coverage and rate of referral for colonoscopy after positive FIT should be improved.

    Locally extensive recurrent breast cancer usually portends a poor prognosis but certain cases can be treated surgically by wide soft-tissue resection as well as full-thickness chest wall resection (FTCWR). The resulting defect usually necessitates immediate flap coverage. The aim of this study was to assess local control, morbidity, choice of flap reconstruction, patient selection and overall long-term survival following surgical salvage of patients with chest wall recurrent breast cancer. Forty patients were treated with wide soft-tissue resection and immediate flap reconstruction from 1984 to 2011 in a single institution. Demographic, treatment and mortality data were obtained from patients' files. Mean age at surgery was 54 years. FTCWR was performed in 19 cases including three extended forequarter amputations. Chest wall stabilisation involved a synthetic mesh in 12 patients, fascia lata in two patients, free rib grafts in one patient and synthetic mesh and free rib graft in one patient. Soft-tissue reconstruction consisted of microvascular free flaps in seven patients and pedicled flaps in 33 patients. In-hospital mortality was 0%, 30-day mortality was 5%; there were two re-operations, six minor wound complications and one pulmonary embolism. There were no flap losses. In patients operated on with curative intent (n=31) median disease-free interval was 31 months and median survival was 52 months. In selected cases wide resections for extensive chest wall recurrent breast cancer can result in reasonable local control and survival. Several flap options exist for soft-tissue reconstruction.

    2013-01-01

    Background Recently, some US cohorts have shown a moderate association between red and processed meat consumption and mortality supporting the results of previous studies among vegetarians. The aim of this study was to examine the association of red meat, processed meat, and poultry consumption with the risk of early death in the European Prospective Investigation into Cancer and Nutrition (EPIC). Methods Included in the analysis were 448,568 men and women without prevalent cancer, stroke, or myocardial infarction, and with complete information on diet, smoking, physical activity and body mass index, who were between 35 and 69 years old at baseline. Cox proportional hazards regression was used to examine the association of meat consumption with all-cause and cause-specific mortality. Results As of June 2009, 26,344 deaths were observed. After multivariate adjustment, a high consumption of red meat was related to higher all-cause mortality (hazard ratio (HR) = 1.14, 95% confidence interval (CI) 1.01 to 1.28, 160+ versus 10 to 19.9 g/day), and the association was stronger for processed meat (HR = 1.44, 95% CI 1.24 to 1.66, 160+ versus 10 to 19.9 g/day). After correction for measurement error, higher all-cause mortality remained significant only for processed meat (HR = 1.18, 95% CI 1.11 to 1.25, per 50 g/d). We estimated that 3.3% (95% CI 1.5% to 5.0%) of deaths could be prevented if all participants had a processed meat consumption of less than 20 g/day. Significant associations with processed meat intake were observed for cardiovascular diseases, cancer, and 'other causes of death'. The consumption of poultry was not related to all-cause mortality. Conclusions The results of our analysis support a moderate positive association between processed meat consumption and mortality, in particular due to cardiovascular diseases, but also to cancer.

    To investigate the association between the length of the polymorphic trinucleotide CAG microsatellite repeats in exon 1 of the AR gene and the risk of prostate cancer containing TMPRSS2:ETS fusion genes. This nested case-control study came from subjects enrolled in the Prostate Cancer Prevention Trial and included 195 biopsy-proven prostate cancer cases with a known TMPRSS2:ETS status and 1344 matched controls. There was no association between the CAG repeat length and the risk of TMPRSS2:ETS-positive (odds ratio, 0.97; 95% confidence interval, 0.91-1.04) or TMPRSS2:ETS-negative prostate cancer (odds ratio, 1.04; 95% confidence interval, 0.97-1.11) and in patients with low- or high-grade disease. Our findings suggested that AR CAG repeats are not associated with TMPRSS2:ETS formation in prostate cancer. Published by Elsevier Inc.

    We investigate the familial risks of cancers of the breast and ovary, using data pooled from three population-based case-control studies of ovarian cancer that were conducted in the United States. We base estimates of the frequency of mutations of BRCA1 (and possibly other genes) on the reported occurrence of breast cancer and ovarian cancer in the mothers and sisters of 922 women with incident ovarian cancer (cases) and in 922 women with no history of ovarian cancer (controls). Segregation analysis and goodness-of-fit testing of genetic models suggest that rare mutations (frequency .0014; 95% confidence interval .0002-.011) account for all the observed aggregation of breast cancer and ovarian cancer in these families. The estimated risk of breast cancer by age 80 years is 73.5% in mutation carriers and 6.8% in noncarriers. The corresponding estimates for ovarian cancer are 27.8% in carriers and 1.8% in noncarriers. For cancer risk in carriers, these estimates are lower than those obtained from families selected for high cancer prevalence. The estimated proportion of all U.S. cancer diagnoses, by age 80 years, that are due to germ-line BRCA1 mutations is 3.0% for breast cancer and 4.4% for ovarian cancer. Aggregation of breast cancer and ovarian cancer was less evident in the families of 169 cases with borderline ovarian cancers than in the families of cases with invasive cancers. Familial aggregation did not differ by the ethnicity of the probands, although the number of non-White and Hispanic cases (N = 99) was sparse. 14 refs., 3 figs., 6 tabs.

    The aim of this study was to evaluate whether stage at cancer diagnosis differed according to patient economic status. A total of 10,528 patients with cancer of the stomach, colorectum, breast, or cervix, which are target organs of the Korean National Cancer Screening Program (NCSP; fully implemented in 2005) were extracted from population-based cancer registries. The patients were classified into four groups based on socioeconomic status (SES), as determined using their National Health Insurance (NHI) monthly premium at the time of cancer diagnosis. Cancer stage at diagnosis was defined as early (in situ/local) or late stage (regional/distant) based on the Surveillance, Epidemiology, and End Results (SEER) summary stage. Multivariable logistic regression analysis was performed to estimate the risk of non-local stage using age, residential area, and community deprivation index as covariates. The lowest SES subjects showed significantly higher risks of being diagnosed at a later stage for stomach, colorectal, and female breast cancer, but not for cervical cancer, compared with the highest SES subjects. The estimated ORs were 1.28 (95% CI, 1.10-1.49), 1.29 (95% CI, 1.03-1.61), and 1.35 (95% CI, 1.02-1.81) in the lowest SES subjects with stomach, colorectal, and breast cancer, respectively. In conclusion, later stage diagnoses of stomach, colon, and female breast cancer are still associated with SES in Korea in the era of the NCSP for the lower SES population.

    The effect of BRCA1/2 gene test result on anxiety, depression, cancer-related thought intrusion or avoidance and perceived control over cancer risk was assessed in breast cancer (BC) patients, according to their perceived probability of genetic predisposition to cancer. Two hundred and forty-three (89% response rate) women with BC completed questionnaires after an initial genetic counselling visit (T1), of which 180 (66%) completed questionnaires again after receiving the BRCA1/2 results (T2). The discrepancy between women's perceived probability of cancer genetic predisposition at T1 and the geneticist's computed estimates was assessed. In all, 74% of women received a negative uninformative (NU), 11% a positive BRCA1/2 and 15% an unclassified variant (UV) result. On hierarchical regression analysis, in women with a positive BRCA1/2 result (vs NU or UV), a lower perceived probability of cancer genetic predisposition than objective estimates at T1 predicted lower levels of anxiety at T2 (β=-0.28; Presult (vs NU or positive BRCA1/2), a lower perceived probability of cancer genetic predisposition than objective estimates at T1 predicted higher levels of anxiety (β=0.20; Presult differently affects distress according to women's perceived probability of genetic predisposition before testing.

    Lung uptake, ventricular cavitary dilation and basal myocardial uptake represent abnormalities that have been associated with myocardial ischemia on stress thallium-201 images, but that are supplementary to the conventional assessment of perfusion distribution. These "supplementary" indicators of ischemia were related to the coronary distribution of perfusion abnormalities, the results of electrocardiographic stress testing and to the findings on coronary angiography in 73 patients. Forty patients had multivessel coronary disease; 19 of these had three vessel disease. Perfusion abnormalities were seen in 39 of these 40 patients but were indicative of multivessel coronary disease in only 28 and of three vessel disease in only 6. However, supplementary indicators were present in 33 of 40 patients with multivessel disease and in 15 of 19 with three vessel disease. Furthermore, they were seen in 16 of 22 patients with multivessel disease in whom conventional perfusion abnormalities underestimated the extent of disease, but in only 4 of 12 patients in whom the extent of disease was overestimated. The presence of either perfusion abnormalities in a multivessel distribution or supplementary indicators identified 38 (95%) of 40 patients with multivessel disease. A markedly positive electrocardiographic treadmill test was a less sensitive indicator of multivessel disease, appearing in only 15 of 40 patients. However, it was present in only 4 of 33 patients without multivessel coronary disease and was more specific for that diagnosis than were supplementary scintigraphic indicators (88 versus 67%, p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available The results of multicenter prospective trial for efficacy of combined modality treatment: transurethral resection (TUR + photodynamic therapy (PDT with alasens for bladder cancer are represented in the article. Trials were organized by Research Institute of Organic Intermediates and Dyes and conducted according to clinical protocol approved by Ministry of Health of Russia, at the sites of leading Russian cancer clinical centers. The trial included 45 subjects with verified diagnosis of non-muscle-invasive bladder cancer. Patients underwent TUR of bladder with simultaneous PDT as anti-relapse treatment. Alasens was administered to patients as intravesicular instillation of 3% solution in volume of 50 ml with 1.5–2h exposure (prior to TUR. TUR was performed after instillation. PDT session was conducted immediately after the completion of TUR on a single occasion by means of combined local irradiation on tumor bed with diffuse irradiation on whole urinary bladder mucosa (light dose of local irradiation – 100 J/cm2, diffuse irradiation – 20 J/cm2. Good tolerance of the treatment was noticed, there were no complications. Among 45 patients included in the trial, 35 (78% completed 12 month protocol follow-up without relapse. The recurrence of bladder tumor was registered in 10 (22% cases 6–12 months after TUR+PDT including 3 patients with recurrence 6 months after treatment, 3–9 months and 4–12 months. These patients underwent repeated TUR, whereafter their follow-up in the settings of the clinical trial was disposed. Thus, PDT with alasens after TUR allowed to decrease the recurrence rate of non-muscle-invasive bladder cancer for 1st year after treatment to 22% versus 40–80% for TUR as monotherapy according to literature data. The obtained results were comparable by efficiency with TUR combined with methods of adjuvant treatment for bladder tumors (the recurrence rates for 1-year follow-up after TUR+chemotherapy – 36–44%, after TUR

    Purpose: To analyze the stage-specific management of male breast cancer (MBC) with surgery and radiation therapy (RT) and relate them to outcomes and to female breast cancer (FBC). Methods and Materials: The Surveillance, Epidemiology, and End Results database was queried for all primary invasive MBC and FBC diagnosed from 1973 to 2008. Analyzable data included age, race, registry, grade, stage, estrogen and progesterone receptor status, type of surgery, and use of RT. Stage was defined as localized (LocD): confined to the breast; regional (RegD): involving skin, chest wall, and/or regional lymph nodes; and distant: M1. The primary endpoint was cause-specific survival (CSS). Results: A total of 4276 cases of MBC and 718,587 cases of FBC were identified. Male breast cancer constituted 0.6% of all breast cancer. Comparing MBC with FBC, mastectomy (M) was used in 87.4% versus 38.3%, and breast-conserving surgery in 12.6% versus 52.6% (P<10{sup −4}). For males with LocD, CSS was not significantly different for the 4.6% treated with lumpectomy/RT versus the 70% treated with M alone (hazard ratio [HR] 1.33; 95% confidence interval [CI] 0.49-3.61; P=.57). Postmastectomy RT was delivered in 33% of males with RegD and was not associated with an improvement in CSS (HR 1.11; 95% CI 0.88-1.41; P=.37). There was a significant increase in the use of postmastectomy RT in MBC over time: 24.3%, 27.2%, and 36.8% for 1973-1987, 1988-1997, and 1998-2008, respectively (P<.0001). Cause-specific survival for MBC has improved: the largest significant change was identified for men diagnosed in 1998-2008 compared with 1973-1987 (HR 0.73; 95% CI 0.60-0.88; P=.0004). Conclusions: Surgical management of MBC is dramatically different than for FBC. The majority of males with LocD receive M despite equivalent CSS with lumpectomy/RT. Postmastectomy RT is greatly underutilized in MBC with RegD, although a CSS benefit was not demonstrated. Outcomes for MBC are improving, attributable to improved

    The aim of this study was to assess functional outcomes of patients who had a delayed coloanal anastomosis for a lower third rectal cancer after preoperative radiotherapy. From January 1988 to December 1997, 35 patients with an adenocarcinoma of the lower third of the rectum received preoperative radiotherapy (45Gy) followed by a rectal resection, combining an abdominal and transanal approach. Colorectal resection was performed about 32 days after the end of the radiotherapy. The distal colon stump was pulled through the anal canal. On postoperative day 5 the colonic stump was resected and a direct coloanal anastomosis performed without colostomia diversion. There was no mortality. There was no leakage. One patient had a pelvic abscess. One patient had a necrosis of the left colon requiring reoperation. Another delayed coloanal anastomosis could be performed. Median followup was 43 months (range 6 to 113 months). Functional results were evaluated with a new scoring system including 13 items. Function was considered good in 59% and 70% at 1 and 2 years, respectively. This new procedure is a safe and effective sphincter-preserving operation that avoids a diverting stoma for patients with rectal cancer of the lower third of the rectum. This technique is well adapted for patients receiving preoperative radiotherapy, with low local morbidity and good functional results. Further adaptation could be imagined for a coelioscopic approach.

    Full Text Available Background and Objectives: To study common mental disorders (CMD and other mental health-related variables among community residents with active cancer, cancer survivors and cancer-free respondents. Methods: Data were extracted from the Israeli component of the 28-country World Mental Health Survey. The sample included 165 respondents who reported ever having cancer and 2,282 cancer-free respondents, all aged 39 years and older. The WHO/Composite International Diagnostic Interview (CIDI was used to determine the prevalence rate of CMD. Emotional distress (ED was ascertained with the GHQ-12. Also, respondents were asked about sleep disturbances and mental health service utilization. Results: Respondents with active cancer were more likely to endorse CMD in the past year than cancer-free respondents, 22.1% SE = 6.1 and 7.2% SE = 2.5, respectively (adjusted odds ratio = 2.6, 95% CI 1.2-5.6; to have higher ED scores, M = 27.1 SE = 1.3 and M = 19.8 SE = 0.3, respectively (Wald F = 16.7, p < 0.001; and higher prevalence rates of sleep disturbances, 64.7% SE = 6.5% and 31.5% SE = 4.6%, respectively (adjusted odds ratio = 2.1, 95% CI 1.1-3.9. Cancer survivors did not significantly differ from cancer-free respondents on the study variables. Despite the emotional toll, there were no differences in mental health service utilization among the three cancer groups. Conclusions: Respondents with active cancer residing in the community show enhanced psychopathology. Study findings highlight a double need: to adequately assess mental health problems in persons with cancer and to bridge the treatment gap.

    Evidence from case-control studies, but less so from cohort studies, suggests a positive association between meat intake and risk of lung cancer. Therefore, this association was evaluated in the frame of the European Prospective Investigation into Cancer and Nutrition, EPIC. Data from 478,021 participants, recruited from 10 European countries, who completed a dietary questionnaire in 1992-2000 were evaluated; 1,822 incident primary lung cancer cases were included in the present evaluation. Relative risk estimates were calculated for categories of meat intake using multi-variably adjusted Cox proportional hazard models. In addition, the continuous intake variables were calibrated by means of 24-h diet recall data to account for part of the measurement error. There were no consistent associations between meat consumption and the risk of lung cancer. Neither red meat (RR = 1.06, 95% CI 0.89-1.27 per 50 g intake/day; calibrated model) nor processed meat (RR = 1.13, 95% CI 0.95-1.34 per 50 g/day; calibrated model) was significantly related to an increased risk of lung cancer. Also, consumption of white meat and fish was not associated with the risk of lung cancer. These findings do not support the hypothesis that a high intake of red and processed meat is a risk factor for lung cancer.

    Identification of cancer biomarkers to allow early diagnosis is an urgent need for many types of tumors, whose prognosis strongly depends on the stage of the disease. Canine olfactory testing for detecting cancer is an emerging field of investigation. As an alternative, here we propose to use GC-Olfactometry (GC/O), which enables the speeding up of targeted biomarker identification and analysis. A pilot study was conducted in order to determine odor-active compounds in urine that discriminate patients with gastrointestinal cancers from control samples (healthy people). Headspace solid phase microextraction (HS-SPME)-GC/MS and GC-olfactometry (GC/O) analysis were performed on urine samples obtained from gastrointestinal cancer patients and healthy controls. In total, 91 key odor-active compounds were found in the urine samples. Although no odor-active biomarkers present were found in cancer carrier's urine, significant differences were discovered in the odor activities of 11 compounds in the urine of healthy and diseased people. Seven of above mentioned compounds were identified: thiophene, 2-methoxythiophene, dimethyl disulphide, 3-methyl-2-pentanone, 4-(or 5-)methyl-3-hexanone, 4-ethyl guaiacol and phenylacetic acid. The other four compounds remained unknown. GC/O has a big potential to identify compounds not detectable using untargeted GC/MS approach. This paves the way for further research aimed at improving and validating the performance of this technique so that the identified cancer-associated compounds may be introduced as biomarkers in clinical practice to support early cancer diagnosis.

    Radiotherapy for 67 patients with prostate cancer at the Cancer Institute Hospital during the period of January 1980 to December 1989 is reported. Mean age was 70 years (43-85), and clinical stages were classified as Stage A, 10; B, 24; C, 19; D, 11; not specified (NS), 3. Pathological classification showed well differentiated, 19; moderately differentiated, 20; poorly differentiated, 19; NS, 9. Treatment was performed as follows: radiotherapy (RT) only, 18; RT plus hormonal therapy, 34; RT plus transurethral resection of prostate (TUR-P), 13; RT plus chemotherapy, 2. Local irradiation to the prostate was conducted mainly by bilateral 120 degree arc rotation with 10 MV photons and a mean dose of 69[+-]2 Gy (TDF=118[+-]10). Pelvic lymph nodes were treated by lymphadenectomy in 18 patients, or by whole pelvic radiotherapy in 6 cases. Overall survival (OS) and disease specific survival (DSS) at 5 years were 70% and 87%, and at 10 years 51% and 87%, respectively. According to the clinical staging, OS and DSS at 5 years were, respectively: Stage A, 100%, 100%; Stage B, 89%, 100%; Stage C, 63%, 81%; Stage D, 37%, 65%. Pollakiuria (27%), urinary retention (19%), and bloody stool (8%) were temporally observed as acute radiation complications. Late radiation hazards manifested as rectal bleeding or tarry stool in 2 cases; one with overlappling field resulted in disseminated intravascular coagulation, and the other with mispositioning of the posterior margin of the radiation field, was finally salvaged by artificial anal replacement. Local radiotherapy by bilateral arc rotation method for prostate cancer would be warranted instead of radical prostatectomy. (author).

    AIM: To explore whether intensity modulated radiation therapy (IMRT) in combination with chemotherapy could increase radiation dose to gross tumor volume without severe acute radiation related toxicity by decreasing the dose to the surrounding normal tissue in patients with locally advanced pancreatic cancer.METHODS: Twenty-one patients with locally advanced pancreatic cancer were evaluated in this clinical trial,Patients would receive the dose of IMRT from 21Gy to 30Gy in 7 to 10 fractions within two weeks after conventional radiotherapy of 30Gy in 15 fractions over 3 weeks. The total escalation tumor dose would be 51, 54,57, 60Gy, respectively. 5-fluororacil (5-FU) or gemcitabine was given concurrently with radiotherapy during the treatment course.RESULTS: Sixteen patients who had completed the radiotherapy plan with doses of 51Gy (3 cases), 54Gy (3 cases), 57Gy (3 cases) and 60Gy (7 cases) were included for evaluation. The median levels of CA19-9 prior to and after radiotherapy were 716 U/ml and 255 U/ml respectively (P<0.001) in 13 patients who demonstrated high levels of CA19-9 before radiotherapy. Fourteen patients who suffered from pain could reduce at least 1/3-1/2 amount of analgesic intake and 5 among these patients got complete relief of pain. Ten patients improved in Kamofsky performance status (KPS). The median follow-up period was 8 months and one-year survival rate was 35 %. No patient suffered more than grade Ⅲ acute toxicities induced by radiotherapy.CONCLUSION: Sixty Gy in 25 fractions over 5 weeks with late course IMRT technique combined with concurrent 5-FU chemotherapy can provide a definitely palliative benefit with tolerable acute radiation related toxicity for patients with advanced pancreatic cancer.

    Objective: To evaluate the local tumor control and survival data after transarterial chemoembolization with different drug combinations in the palliative treatment of patients with liver metastases of gastric cancer. Materials and methods: The study was retrospectively performed. 56 patients (mean age, 52.4) with unresectable liver metastases of gastric cancer who did not respond to systemic chemotherapy were repeatedly treated with TACE in 4-week intervals. In total, 310 chemoembolization procedures were performed (mean, 5.5 sessions per patient). The local chemotherapy protocol consisted of mitomycin alone (30.4%), mitomycin and gemcitabine (33.9%), or mitomycin, gemcitabine and cisplatin (35.7%). Embolization was performed with lipiodol and starch microspheres. Local tumor response was evaluated by MRI according to RECIST. Survival data from first chemoembolization were calculated according to the Kaplan–Meier method. Results: The local tumor control was: complete response in 1.8% (n = 1), partial response in 1.8% (n = 1), stable disease in 51.8% (n = 29) and progressive disease in 44.6% (n = 25) of patients. The 1-, 2-, and 3-year survival rate from the start of chemoembolization were 58%, 38%, and 23% respectively. The median and mean survival times were 13 and 27.1 months. A Statistically significant difference between patients treated with different chemotherapy protocols was noted (ρ = 0.045) with the best survival time in the mitomycin, gemcitabine and cisplatin group. Conclusion: Transarterial chemoembolization is a minimally invasive therapy option for palliative treatment of liver metastases in patients with gastric cancer.

    Purpose To evaluate the feasibility of transanal total mesorectal excision (TME) in patients with rectal cancer. Methods This study enrolled 12 patients with clinically node negative rectal cancer located 4–12 cm from the anal verge who underwent transanal endoscopic TME with the assistance of single port laparoscopic surgery between September 2013 and August 2014. The primary endpoint was TME quality; secondary endpoints included number of harvested lymph nodes and postoperative complications within 30 days (NCT01938027). Results The 12 patients included 7 males and 5 females, of median age 59 years and median body mass index 24.2 kg/m2. Tumors were located on average 6.7 cm from the anal verge. Four patients (33.3%) received preoperative chemoradiotherapy. Median operating time was 195 minutes and median blood loss was 50 mL. There were no intraoperative complications and no conversions to open surgery. TME was complete or nearly complete in 11 patients (91.7%). Median distal resection and circumferential resection margins were 18.5 mm and 10 mm, respectively. Median number of harvested lymph nodes was 15. Median length of hospital stay was 9 days. There were no postoperative deaths. Six patients experienced minor postoperative complications, including urinary dysfunction in 2, transient ileus in 3, and wound abscess in 1. Conclusion This pilot study showed that high-quality TME was possible in most patients without serious complications. Transanal TME for patients with rectal cancer may be feasible and safe, but further investigations are necessary to evaluate its long-term functional and oncologic outcomes and to clarify its indications.

    Complete surgical resection is the most effective curative treatment for lung cancer. However, many patients with lung cancer also have severe COPD which increases their risk of postoperative complications and their likelihood of being considered "inoperable." Preoperative pulmonary rehabilitation (PR) has been proposed as an intervention to decrease surgical morbidity but there is no established protocol and no randomized study has been published to date. We tested two preoperative PR interventions in patients undergoing lung cancer resection and with moderate-severe COPD in a randomized single blinded design. Outcomes were length of hospital stay and postoperative complications. The first study tested 4 weeks of guideline-based PR vs. usual care: that study proved to be very difficult to recruit as patients and providers were reluctant to delay surgery. Nine patients were randomized and no differences were found between arms. The second study tested ten preoperative PR sessions using a customized protocol with nonstandard components (exercise prescription based on self efficacy, inspiratory muscle training, and the practice of slow breathing) (n=10) vs. usual care (n=9). The PR arm had shorter length of hospital stay by 3 days (p=0.058), fewer prolonged chest tubes (11% vs. 63%, p=0.03) and fewer days needing a chest tube (8.8 vs. 4.3 days p=0.04) compared to the controlled arm. A ten-session preoperative PR intervention may improve post operative lung reexpansion evidenced by shorter chest tube times and decrease the length of hospital stay, a crude estimator of post operative morbidity and costs. Our results suggest the potential for short term preoperative pulmonary rehabilitation interventions in patients with moderate-severe COPD undergoing curative lung resection. 4 weeks of conventional preoperative PR seems non feasible.

    Full Text Available Aim: This study evaluated whether using supplementary files for removing root canal filling residues after ProTaper Universal Retreatment files (RFs increased the debris extrusion apically. Materials and Methods: Eighty mandibular premolars with single root and canal were instrumented with ProTaper Universal rotary system (SX-F3 and obturated. The samples were divided randomly into four groups (n = 20. Group 1 served as a control; only ProTaper Universal RFs D1-D3 were used, and the extruded debris was weighed. Groups 2, 3, and 4 were the experimental groups, receiving a twofold retreatment protocol: Removal of the bulk, followed by the use of supplementary files. The bulk was removed by RFs, followed by the use of ProTaper NEXT (PTN, WaveOne (WO, and Self-Adjusting File (SAF for removal of the remaining root filling residues. Debris extruded apically were weighed and compared to the control group. Statistical analysis was performed using one-way analysis of variance (ANOVA and post hoc Tukey′s test. Results: All the three experimental groups presented significant difference (P < .01. The post hoc Tukey′s test confirmed that Group 4 (SAF exhibited significantly less (P < .01 debris extrusion between the three groups tested. Conclusion: SAF results in less extrusion of debris when used as supplementary file to remove root-filling residues, compared to WO and PTN.

    Studies suggest that obesity is associated with lower risk of prostate cancer but more aggressive cancers. As obesity lowers PSA levels, these observations may be influenced by detection bias. We examined the association between obesity and risk of low- and high-grade prostate cancer in REDUCE, in which biopsies were largely independent of PSA. The REDUCE study tested dutasteride for prostate cancer risk reduction in men with a PSA of 2.5 to 10.0 ng/mL and a negative biopsy. Study participants included 6,729 men who underwent at least one on-study biopsy. The association between baseline body mass index (BMI obese) and risk of high-grade (Gleason ≥7) or low-grade prostate cancer (Gleason prostate cancer was examined using multinomial logistic regression. Overall, 1,739 men (27%) were normal weight, 3,384 (53%) overweight, and 1,304 (20%) were obese. Obesity was associated with lower risk of low-grade prostate cancer in both univariable (OR, 0.74; P = 0.001) and multivariable analyses (OR, 0.79; P = 0.01). In univariable analysis, obesity was not associated with high-grade prostate cancer (OR, 1.08; P = 0.50). However, in multivariable analysis, obesity was associated with increased risk of high-grade prostate cancer (OR, 1.28; P = 0.042). This analysis was not able to address how obesity may influence prostate cancer progression. Obesity is associated with decreased risk of low-grade and increased risk of high-grade prostate cancer. These data provide further support to the hypothesis that obesity is associated with aggressive prostate cancer. Obesity is linked with aggressive prostate cancer. Avoiding obesity may prevent the risk of developing high-grade prostate cancer. ©2014 American Association for Cancer Research.

    We demonstrate an equivalence between reproducing kernel Hilbert space (RKHS) embeddings of conditional distributions and vector-valued regressors. This connection introduces a natural regularized loss function which the RKHS embeddings minimise, providing an intuitive understanding of the embeddings and a justification for their use. Furthermore, the equivalence allows the application of vector-valued regression methods and results to the problem of learning conditional distributions. Using this link we derive a sparse version of the embedding by considering alternative formulations. Further, by applying convergence results for vector-valued regression to the embedding problem we derive minimax convergence rates which are O(\\log(n)/n) -- compared to current state of the art rates of O(n^{-1/4}) -- and are valid under milder and more intuitive assumptions. These minimax upper rates coincide with lower rates up to a logarithmic factor, showing that the embedding method achieves nearly optimal rates. We study o...

    Data are lacking with regard to participants' perspectives on return of genetic research results to relatives, including after the participant's death. This paper reports descriptive results from 3,630 survey respondents: 464 participants in a pancreatic cancer biobank, 1,439 family registry participants, and 1,727 healthy individuals. Our findings indicate that most participants would feel obligated to share their results with blood relatives while alive and would want results to be shared with relatives after their death.

    We evaluated the failure pattern of the celiac axis, gastric lymph node, and treatment outcome in the upper and mid-esophageal region of cancer patients treated by definitive radiotherapy, except when treating the celiac axis and gastric lymph node for treatment volume, retrospectively. Materials and Methods: The study constituted the evaluation 108 patients with locally advanced esophageal cancer receiving radiotherapy or a combination of radiotherapy and chemotherapy at Chonbuk National University Hospital from January 1986 to December 2006. In total, 82 patients treated by planned radiotherapy, except when treating the celiac axis and gastric lymph node for treatment volume, were analysed retrospectively. The study population consisted of 78 men and 2 women (mean age of 63.2 years). In addition, 51 patients received radiotherapy alone, whereas 31 patients received a combination of radiation therapy and chemotherapy. The primary cancer sites were located in the upper portion (17 patients), and mid portion (65 patients), respectively. Further, the patients were in various clinical stages including T1N0-1M0 (7 patients), T2N0-1M0 (18 patients), T3N0-1M0 (44 patients) and T4N0-1M0 (13 patients). The mean follow up period was 15 months. Results: The various treatment outcomes included complete response (48 patients), partial response (31 patients) and no response (3 patients). The failure patterns of the lymph node were comprised of the regional lymph node (23 patients) and the distance lymph node which included celiac axis and gastric lymph node (13 patients). However, metastasis was not observed in the regional and distant lymph node in 10 patients, whereas 36 patients were not evaluated. Furthermore, of the 13 patients who developed celiac axis and gastric lymph node metastases, 3 were in stage T1N0-1M0 and 10 were in stage T2-4N0-1M0. A complete response appeared in 12 patients, whereas a partial response appeared in 1 patient. The mean survival time of the

    To evaluate recent improvements in lung cancer screening, we compared the results of recently conducted lung cancer screening with those of a previous screening. This study compared the survival of lung cancer patients detected by lung cancer screening conducted between 1976 and 1984 (early period with that conducted between 1989 and 1997 (late period. Two hundred seventy-six patients with lung cancer were detected in the early period and 541 patients with lung cancer were detected in the late period. The median survival time (late : 49.8 vs. early : 27.8 months and the 5-year survival rate (late : 47.8 vs. early : 34.8% of the patients with lung cancer detected in the late period were significantly better than those in the early period (p = 0.0054. Among patients undergoing resection, the proportion of pathological stage I patients in the late period was significantly higher than that in the early period (late : 60.8 vs. early : 54.9%, p = 0.005. Multivariate analysis showed that the screening time period was a significant prognostic factor (hazard ratio = 0.685, 95% confidence interval : 0.563-0.832, p = 0.0002. These results were consistent with the findings of case-control studies of lung cancer screening programs in the late period recently conducted in Japan, which also showed a greater efficacy for screening than for previous case-control studies in the early period.

    Full Text Available The aim of this study was to evaluate the reduction in volume of arm lymphedema secondary to breast cancer therapy utilizing an exercise facilitating device. Twenty-one women with arm lymphedema resulting from the surgical and radiotherapeutic treatment of breast cancer were randomly selected. Evaluation was made by water-displacement volumetry before and after each session. The patients were submitted to a series of active exercises using a facilitating device for four 12-minute sessions with intervals of 3 minutes between sessions in the sitting position with alignment of the spinal column. The lymphedematous arm was maintained under compression using a cotton-polyester sleeve. The active exercising device used was a mobile flexion bar fixed on a metal base at a height of 30 cm from the tabletop and at a distance of 10 cm from the patient’s body. The paired t-test was utilized for statistical analysis with an alpha error of 5% (p-value ≤0.05 being considered significant. The initial mean volume of the arms was 2,089.9 and the final volume was 2,023.0 mL with a mean loss of 66.9 mL (p-value <0.001. In conclusion, active exercises utilizing facilitating devices can contribute to a reduction in size of lymphedematous limbs.

    Laser Immunotherapy is an experimental treatment modality for late-stage, metastatic tumors, which targets solid primary and/or secondary tumors and utilizes an autologous vaccine-like approach to stimulate immune responses. Specifically, laser immunotherapy combines laser-induced in situ tumor devitalization with an immunoadjuvant for local immunostimulation. Here we report the initial results from a human breast cancer pilot trial with laser immunotherapy. Six stage III and IV cancer patients were treated, all of which were considered to be out of all other options, and preliminary data at the three-month examination are presented. The immediate goal of the trial was to determine the patient tolerance and the toxicity of the therapy, the optimal dose for the alteration of the course of the disease, and the reduction of the tumor burden. Each patient was individually evaluated for toxicity tolerance through physical exams and by appropriate supplemental and routine laboratory tests. Observable tumors in patients were followed with physical examination and radiological evaluations. Treatment efficacy was judged by the size and number of local and distant metastases before and after treatment.

    Twenty patients with hypopharyngeal cancers (HPCs) who underwent radical radiotherapy (RT) from April 1983 to August 1994 were analyzed retrospectively. Seventeen patients (85%) were treated with radical RT alone, and three patients (15%) were treated with radical RT with salvage surgery. Clinical examination showed that 30% (6/20) of patients had T3-4 diseases and 50% (10/20) had lymph node metastases. Primary tumor sites were: 16 (80%) in the piriform sinus, two (10%) in the posterior pharyngeal wall and two (10%) in the postcricoid area. Patients were treated with daily fractions of 1.8 to 2.0 Gy, with total doses of 60 Gy or more. Distant metastases were detected in five patients (25%) after completion of radical RT. The preservation rate of the pharyngo-larynx at 2-years without loco-regional failure was 25% (5/20), all in patients with N0 pyriform sinus cancer. The 5-year cumulative survival rate for all 20 patients was 30% (6/20), with 100% (4/4) in stage I, 33% (1/3) in stage II, 33% (1/3) in stage III, and 0% (0/10) in stage IV. Univariate analysis of patients' characteristics revealed that stage (stage I+II versus stage III+IV) and N-stage (N0 versus N+) were significantly related to 5-year survival (p<0.05). These results suggest that controlling lymph-node-metastasis in HPCs by RT alone is difficult. (author)

    The optimal treatment for base of tongue cancer remains unclear, especially in advanced stages. We retrospectively review 84 previously untreated patients that underwent a transhyoid resection of a base of tongue carcinoma. Sixty-four patients (76%) underwent postoperative radiotherapy. Five patients had stage II disease, 6 had stage III, 58 had stage IVA, and 15 had stage IVB. The overall recurrence rate was 68%. Five-year disease-specific survival rates by stage were 100%, 67%, 27%, and 8% for stage II to IVB, respectively (p = .0007). Multivariate analysis showed that the presence of lymph node metastases was an independent predictor of reduced disease-specific survival rates (p = .02). All patients maintained an intelligible voice, and oral alimentation was successfully recovered in 97.5% of them. The transhyoid approach allowed adequate resection of base of tongue cancers with low morbidity and acceptable functional results, but the oncologic outcomes in advanced stages are poor.

    Purpose While targeted sequencing improves outcomes for many cancer patients, how somatic and germline whole-exome sequencing (WES) will integrate into care remains uncertain. Methods We conducted surveys and interviews, within a study of WES integration at an academic center, to determine oncologists' attitudes about WES and to identify lung and colorectal cancer patients' preferences for learning WES findings. Results 167 patients (85% white, 58% female, mean age 60) and 27 oncologists (22% female) participated. Although oncologists had extensive experience ordering somatic tests (median 100/year), they had little experience ordering germline tests. Oncologists intended to disclose most WES results to patients but anticipated numerous challenges in using WES. Patients had moderately low levels of genetic knowledge (mean 4 correct of 7). Most patients chose to learn results that could help select a clinical trial, pharmacogenetic and positive prognostic results, and results suggesting inherited predisposition to cancer and treatable non-cancer conditions (all ≥95%). Fewer chose to receive negative prognostic results (84%) and results suggesting predisposition to untreatable non-cancer conditions (85%). Conclusion The majority of patients want most cancer-related and incidental WES results. Patients' low levels of genetic knowledge and oncologists' inexperience with large-scale sequencing presage challenges to implementing paired WES in practice. PMID:26866579

    The term "teachable moment" (TM) has been used to describe a life transition or event which motivates an individual to change a behavior or presents an opportunity to intervene to prompt behavior change. We examined whether receipt of a false positive ovarian cancer (OC) screening result may represent a TM. 403 women participating in an OC screening program completed questionnaires assessing demographic, clinical, behavioral, and psychosocial information. The TM was operationalized as expressed interest in receiving health-related information. We hypothesized that among women receiving a false positive screening test result, those women who had experienced greater personal perceived risk for OC as well as distress would be more interested in receiving health-related information than women receiving a normal result. Analyses revealed that women receiving a false positive screening result were less interested in receiving health-related information than women receiving a normal screening result. For women receiving a false positive result, expressed interest in receipt of health-related information was only modestly related to distress and related even less to perceptions of OC risk. Our data do not support viewing a false positive OC screening result as a TM. Potential explanations for the current findings as well as recommendations for future research investigating the TM are discussed.

    The Mediterranean Diet (MD) has been associated with reduced mortality and risk of cardiovascular diseases, but there is only limited evidence on cancer. We investigated the relationship between adherence to MD and risk of postmenopausal breast cancer (and estrogen/progesterone receptor subtypes, ER/PR). In the Netherlands Cohort Study, 62,573 women aged 55-69 years provided information on dietary and lifestyle habits in 1986. Follow-up for cancer incidence until 2007 (20.3 years) consisted of record linkages with the Netherlands Cancer Registry and the Dutch Pathology Registry PALGA. Adherence to MD was estimated through the alternate Mediterranean Diet Score excluding alcohol. Multivariate case-cohort analyses were based on 2,321 incident breast cancer cases and 1,665 subcohort members with complete data on diet and potential confounders. We also conducted meta-analyses of our results with those of other published cohort studies. We found a statistically significant inverse association between MD adherence and risk of ER negative (ER-) breast cancer, with a hazard ratio of 0.60 (95% Confidence Interval, 0.39-0.93) for high versus low MD adherence (ptrend  = 0.032). MD adherence showed only nonsignificant weak inverse associations with ER positive (ER+) or total breast cancer risk. In meta-analyses, summary HRs for high versus low MD adherence were 0.94 for total postmenopausal breast cancer, 0.98 for ER+, 0.73 for ER- and 0.77 for ER - PR- breast cancer. Our findings support an inverse association between MD adherence and, particularly, receptor negative breast cancer. This may have important implications for prevention because of the poorer prognosis of these breast cancer subtypes. © 2017 UICC.

    A 37-year-old male and a 12-year-old female presented with non-lesional epilepsy arising from the supplementary motor area in the medial frontal cortex, manifesting as daily brief tonic seizures involving the bilateral extremities, which were intractable to multiple antiepileptic medications. During the seizure, there was no impairment of awareness, and the tonus was always higher in the limbs contralateral to the epileptogenic hemisphere in both patients. Scalp EEG detected midline epileptiform discharges. Three-tesla MR imaging using the FLAIR and short tau inversion recovery sequences, interictal IMP-SPECT, IMZ-SPECT, and FDG-PET detected no focal abnormalities in either patient. Invasive intracranial EEG evaluation was performed using chronically implanted subdural electrodes on the interhemispheric frontoparietal cortices, based mainly on the seizure semiology and the associated EEG findings. Intracranial EEG successfully identified the location of the seizure onset in the supplementary motor area in the medial frontal cortex. Focal cortical resection including the area of seizure onset resulted in freedom from seizures and significant improvement in both patients. Histological study revealed focal cortical dysplasia in both patients. Recognition of the typical seizure semiology is very important in the correct diagnosis and surgical treatment of supplementary motor area epilepsy, especially in the absence of MR imaging lesions.

  16. Provision of Supplementary Load Frequency Control via Aggregation of Air Conditioning Loads

    Full Text Available The integration of large-scale renewable energy poses great challenges for the operation of power system because of its increased frequency fluctuations. More load frequency control (LFC resources are demanded in order to maintain a stable system with more renewable energy injected. Unlike the costly LFC resources on generation side, the thermostatically controlled loads (TCLs on the demand side become an attractive solution on account of its substantial quantities and heat-storage capacity. It generally contains air conditioners (ACs, water heaters and fridges. In this paper, the supplementary LFC is extracted by the modeling and controlling of aggregated ACs. We first present a control framework integrating the supplementary LFC with the traditional LFC. Then, a change-time-priority-list method is proposed to control power output taking into account customers’ satisfaction. Simulations on a single-area power system with wind power integration demonstrate the effectiveness of the proposed method. The impact of ambient temperature changes and customer preferences on room temperature is also involved in the discussion. Results show that the supplementary LFC provided by ACs could closely track the LFC signals and effectively reduce the frequency deviation.

    Breast feeding and supplementary food patterns were studied in 3 villages, of Udon Thani Province in Northeast Thailand. All children of 58 mothers were breast fed. Moreover, 42 mothers (72.4%), advised by health workers, fed their children with colostrum. Those who did not give colostrum believed that colostrum may cause diarrhea. Fifty-one (87.9%) children were fed Kaw Yam, northeast native food made out of baked chewed banana and sticky rice, within 1-7 days after birth. The mothers believed that the food will fill the child's stomach, and consequently, her baby will stop to cry. Powder milk was also given to the child as supplementary food. A powder milk had a high social value for the mother and also health worker advised them to feed the children with it. Rice porridge was additionally supplemented at the age of 6-8 months until weaning or, at the time when the child had two front teeth. Child's weaning was forced by applying the nipples with local bitter tasting herb. This study indicates that any health education within a community should be aware of traditional belief and customs of the population. The promotion of proper breast feeding, and the introduction of supplementary food to children should be consider traditional beliefs and combine it with health educational means, which will result in a better adoptability of the villagers to the promotion of adequate infant feeding.

    The results of cranial irradiation for brain metastases (BM) of small cell lung cancer (SCLC) were investigated. Of a total of 67 patients, aged 33 to 80, 47 patients received whole brain irradiation ranging from 30 to 57.6 Gy (mean: 44.3 Gy), and the remaining 20 with localized BM received boost irradiation up to 40-60 Gy (mean: 52.5 Gy) totally on the policy of high dose irradiation. Response to treatment was evaluated by the neurological function (NF) score proposed by Radiation Therapy Oncology Group (RTOG), as well as tumor size on computed tomography (CT) or magnetic resonance imaging (MRI), or both. The results were as follows: improvement of NF in 70%, complete response in 36%, partial response in 51%, no change in 10% and progressive disease in 1%, respectively. Overall survival rates at 1-, and 2-years from the start of cranial irradiation were 26% and 9%, respectively, resulting in a median survival time (MST) of 6.2 months. The patients who already had BM at the diagnosis of lung cancer survived much longer (p<0.01) than those who developed brain metastases after the initial treatment. Five patients with a small BM detected only by MRI had a survival of 12.9 months in MST. Multivariate analysis showed the significant prognostic factors to be a low level of serum lactate dehydrogenase, a primary lesion well-controlled at the time of cranial irradiation and age younger than 62. Our data suggest that high dose irradiation to control BM is necessary to extend survival. (author)

    The gold standard of treatment of cancer of the lateral wall of the oropharynx continues to be unclear, especially in advanced stages. In this study, we report our experience with surgical treatment of these cancers and describe the functional and oncological results of the procedures. Retrospective review. A total of 155 previously untreated patients with squamous cell carcinoma of the lateral wall of the oropharynx who underwent a surgical resection of the lesion at our department from January 1990 to January 2008 were included. Sixty-seven percent of these patients received postoperative radiotherapy. The records of these patients were reviewed to obtain measures such as local and regional control, disease-specific survival, and speech and swallowing function. Six patients had a stage I disease, 15 had a stage II disease, 31 had a stage III disease, 86 had a stage IVA, and 17 had stage IVB disease. The overall recurrence rate was 60%, and the local recurrence rate was 40%. The 5-year overall survival and disease-specific survival rates were 33% and 43%, respectively. Five-year disease-specific survival rates by stage were as follows: 100%, 59%, 57%, 31%, and 33% for stages I to IVB, respectively. Multivariate analysis showed two parameters that were independent predictors of a reduced disease-specific survival: cervical lymph node metastases pN2-3 (P = .027) and primary tumor classified as pT3-4 (P = .029). In 122 patients, a tracheotomy was performed, and it couldn't be sealed in 23% of them. Oral alimentation was successfully recovered in 93% of the patients. Surgical treatment of cancer of the lateral wall of the oropharynx provides acceptable oncological and functional results, especially in early and moderately advanced stages (stages I-III). In advanced stages (stage IV), we obtained good functional preservation rates but poor oncological outcomes. Consequently, these groups of patients could be considered for another treatment modality, such as

    To evaluate the results and prognostic factors for postoperative adjuvant radiation therapy in patients at stages I and II of endometrial cancer. Materials and Methods: Between January 1991 and December 2006, 35 patients with FIGO stages I and II disease, who received adjuvant radiation therapy following surgery for endometrial cancer at Ewha Womans University Hospital, were enrolled in this study. A total of 17 patients received postoperative pelvic external beam radiation therapy; whereas, 12 patients received vaginal brachytherapy alone, and 6 patients received both pelvic radiation therapy and vaginal brachytherapy. Results: The median follow-up period for all patients was 54 months. The 5-yr overall survival and disease-free survival rates for all patients were 91.4% and 81.7%, respectively. The 5-yr overall survival rates for low-risk, intermediate-risk, and high-risk groups were 100%, 100% and 55.6%, respectively. In addition, the 5-yr disease-free survival rates were 100%, 70.0%, and 45.7%, respectively. Although no locoregional relapses were identified, distant metastases were observed in 5 patients (14%). The most common site of distant metastases was the lung, followed by bone, liver, adrenal gland, and peritoneum. A univariate analysis revealed a significant correlation between distant metastases and risk-group (p=0.018), pathology type (p=0.001), and grade (p=0.019). A multivariate analysis also revealed that distant metastases were correlated with pathology type (p=0.009). Papillary, serous and clear cell carcinoma cases demonstrated a poor patient survival rate compared to cases of endometrioid adenocarcinoma or adenosquamous carcinoma. The most common complication of pelvic external beam radiation therapy was enteritis (30%), followed by proctitis, leucopenia, and lymphedema. All these complications were of RTOG grades 1 and 2; no grades 3 and 4 were observed. Conclusion: For the low-risk and intermediate-risk groups (stages 1 and 2) endometrial

    Results of large prospective trials, often based on selected series and optimal treatment techniques, indicate that breast conserving therapy is appropriate for most patients with early breast cancer. Questions remain regarding the therapeutic outcome in common practice. We report on a series of 206 consecutive, unselected patients treated with current radiotherapy procedures. The Kaplan-Meier evaluation showed 5- and 8-year survival rates (93%, 91%), distant disease-free survival rates (87%, 85%) and local relapse-free survival rates (90%, 88%) that were comparable to those of the conservative arms in reported randomised trials and to the data from retrospective studies reported by authoritative institutions. However, subanalysis according to prognostic factors such as menopausal status, age and axillary nodal status was of limited value, due to the small number of cases. (orig.).

    We studied the therapeutic results and prognostic factors in 63 cases of small cell lung cancer (SCLC) experienced in our hospital over the past eight years. In the group initially treated with combination chemotherapy using COMP-VAD, the survival period was significantly prolonged. Use of adjuvant radiotherapy from the beginning had no effect on improvement in the survival period, but the period until local recurrences tended to be prolonged. Prognostic factors influencing survival were analyzed by the log rank test and generalized Wilcoxon test and multivariate analysis by the proportional hazard model of Cox. Statistical significance using univariate analysis was found for six factors (PS, clinical stage, LDH, albumin, treatment protocols, treatment response). The strong prognostic factors determined by multivariate analysis were, in the order of importance, chemotherapy protocol, initial PS, and treatment response.

    Full Text Available Aim: Sentinel lymph node biopsy (SLNB in breast cancer patients targets the evaluation of the initial lymph node (SLN which drains the primary tumor. The morbidity of unnecessary axillary dissection can be avoided by intensive preoperative assessment of SLN. Methods: Twenty-six consecutive patients who had been surgically treated for early-stage breast cancer between March 2005 and August 2007 were evaluated. Blue dye (methylene blue method was used to detect SLN. All patients underwent axillary lymph node dissection following SLNB. NCSS program was used for statistical analysis. Chi-square test was used in the comparison of binary groups. Results: Except for one, all patients were female. The mean age of the patients was 56 (29-76 years. While 13 patients underwent modified radical mastectomy (=mastectomy+axillary dissection, the remaining 13 patients underwent breast preserving surgery (lumpectomy+axillary dissection. SLN could not be found in 2 patients (7.6%.The male patient was one of these 2 patients and both of them were positive for axillary node metastases. The detection rate of SLN, specificity, negative predictive value, positive predictive value, sensitivity, false negativity, and reliability were 92.3%, 92.8%, 86%, 90.9%, 83.3%, 16.6%, and 88.4%, respectively. Conclusion: Our result support the hypothesis that SLNB with blue dye alone is a reliable technique and, surgery clinics should use it prior to axillary dissection to test their own success during the learning curve.

    We analyzed the treatment outcomes and prognostic factors of breast conserving surgery, followed by postoperative radiotherapy. Materials and Methods: A total of 424 breast cancer patients treated with breast conserving surgery and postoperative radiotherapy between February 1992 and January 2001 were retrospectively analyzed. A quadrantectomy and axillary lymph node dissection was performed in 396 patients. A total of 302 patients had T1 disease, and 122 patients had T2 disease. Lymph node involvement was confirmed in 107 patients. Whole breast irradiation was administered at up to 50.4 Gy in 28 fractions, followed by a 10 Gy boost in 5 fractions to the tumor bed. In addition, 57 patients underwent regional lymph node irradiation. Moreover, chemotherapy was administered in 231 patients. A regimen consisting of cyclophosphamide, methotrexate, and 5-fluorouracil was most frequently used with 170 patients. The median follow-up time was 64 months. Results: The 5-year local control rate was 95.6%. During the follow-up period, local tumor recurrence was observed in 15 patients. The 5-year overall and disease-free survival rates were 93.1% and 88.7%, respectively. The 5-year overall survival rates, by stage, were 94.8% for stage I, 95.0% for stage IIA, 91.1% for stage IIB, 75.9% for stage IIIA, and 57.1% for stage IIIC. As for disease-free survival, the corresponding figures, by stage (in the same order), were 93.1%, 89.4%, 82.8%, 62.0%, and 28.6%, respectively. The advanced N stage (p=0.0483) was found to be a significant prognostic factor in predicting poor overall survival, while the N stage (p=0.0284) and age at diagnosis (p=0.0001) were associated with disease-free survival. Conclusion: This study has shown that breast conserving surgery and postoperative radiotherapy for early breast cancer results was excellent for local control and survival.

    Background: Periodontal pathogens have been isolated from precancerous and cancerous lesions and also shown to promote a procarcinogenic microenvironment. Few studies have examined periodontal disease as a risk factor for total cancer, and none have focused on older women. We examined whether periodontal disease is associated with incident cancer among postmenopausal women in the Women's Health Initiative Observational Study.Methods: Our prospective cohort study comprised 65,869 women, ages 54 to 86 years. Periodontal disease information was obtained via self-report questionnaires administered between 1999 and 2003, whereas ascertainment of cancer outcomes occurred through September 2013, with a maximum follow-up period of 15 years. Physician-adjudicated incident total cancers were the main outcomes and site-specific cancers were secondary outcomes. HRs and 95% confidence intervals (CI) were calculated using Cox proportional hazards regression. All analyses were conducted two-sided.Results: During a mean follow-up of 8.32 years, 7,149 cancers were identified. Periodontal disease history was associated with increased total cancer risk (multivariable-adjusted HR, 1.14; 95% CI, 1.08-1.20); findings were similar in analyses limited to 34,097 never-smokers (HR, 1.12; 95% CI, 1.04-1.22). Associations were observed for breast (HR, 1.13; 95% CI, 1.03-1.23), lung (HR, 1.31; 95% CI, 1.14-1.51), esophagus (HR, 3.28; 95% CI, 1.64-6.53), gallbladder (HR, 1.73; 95% CI, 1.01-2.95), and melanoma skin (HR, 1.23; 95% CI, 1.02-1.48) cancers. Stomach cancer was borderline (HR, 1.58; 95% CI, 0.94-2.67).Conclusions: Periodontal disease increases risk of total cancer among older women, irrespective of smoking, and certain anatomic sites appear to be vulnerable. Impact: Our findings support the need for further understanding of the effect of periodontal disease on cancer outcomes.

    Indian women with breast cancer are usually diagnosed in advanced stages leading to poor survival. Improving breast awareness and increasing access to early diagnosis and adequate treatment has been advocated for breast cancer control. We implemented a program to increase awareness on breast cancer and access to its early detection in an occupational health care scheme in Mumbai, India. Breast awareness brochures were mailed annually between June 2013 and June 2016 to a cohort of 22,500 eligible women aged 30-69 years old receiving universal health care from an occupational health care scheme comprising of primary health centres and a referral secondary care hospital in Mumbai. Women with suspected breast cancers were provided with diagnostic investigations and treatment. Socio-demographic information and tumour characteristics were compared between the breast awareness pre-intervention period (Jan 2005-May 2013) and the breast awareness intervention period after four rounds of mailers (June 2013-June 2016). The proportion of women with early tumours and axillary lymph node negative cancers increased from 74% to 81% and 46% to 53% respectively, between the two periods. While the proportion of patients receiving breast conserving surgery increased from 39% to 51%, the proportion receiving chemotherapy decreased from 84% to 56%. Interim results following efforts to improve breast awareness and access to care in a cohort of women in an occupational health care scheme indicate early detection and more conservative treatment of breast cancers. Creating awareness and improving access to care may result in cancer down-staging.

    Few studies have examined the cancer incidence trends in the state of Texas, and no study has ever been conducted to compare the temporal trends of breast and colorectal cancer incidence in Texas with those of the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) in the United States. This study aimed to conduct a parallel comparison between the Texas Cancer Registry and the National Cancer Institute's SEER on cancer incidence from 1995 to 2011. A total of 951,899 breast and colorectal cancer patients were included. Age-adjusted breast cancer incidence was 134.74 per 100,000 in Texas and 131.78 per 100,000 in SEER in 1995-2011, whereas age-adjusted colorectal cancer incidence was 50.52 per 100,000 in Texas and 49.44 per 100,000 in SEER. Breast cancer incidence increased from 1995 to 2001, decreased from 2002 to 2006, and then remained relatively stable from 2007 to 2011. For colorectal cancer, the incidence increased in 1995-1997, and then decreased continuously from 1998 to 2011 in Texas and SEER areas. Incidence rates and relative risks by age, gender and ethnicity were identical between Texas and SEER.

    A carbohydrate-rich diet, resulting in high blood glucose and insulin, has been hypothesized as involved in colorectal cancer etiology. We investigated dietary glycemic index (GI) and glycemic load (GL), in relation to colorectal cancer, in the prospectively recruited EPIC-Italy cohort. After a median 11.7 years, 421 colorectal cancers were diagnosed among 47,749 recruited adults. GI and GL were estimated from validated food frequency questionnaires. Multivariable Cox modeling estimated hazard ratios (HRs) for associations between colorectal cancer and intakes of total, high GI and low GI carbohydrate and GI and GL. The adjusted HR of colorectal cancer for highest versus lowest GI quartile was 1.35; 95% confidence interval (CI) 1.03-1.78; p trend 0.031. Increasing high GI carbohydrate intake was also significantly associated with increasing colorectal cancer risk (HR 1.45; 95% CI 1.04-2.03; p trend 0.034), whereas increasing low GI carbohydrate was associated with reducing risk (HR 0.73; 95% CI 0.54-0.98; p trend 0.033). High dietary GI and high GI carbohydrate were associated with increased risks of cancer at all colon sites (HR 1.37; 95% CI 1.00-1.88, HR 1.80; 95% CI 1.22-2.65, respectively), whereas high GI carbohydrate and high GL were associated with increased risk of proximal colon cancer (HR 1.94; 95% CI 1.18-3.16, HR 2.01; 95% CI 1.08-3.74, respectively). After stratification for waist-to-hip ratio (WHR), cancer was significantly associated with GI, and high GI carbohydrate, in those with high WHR. These findings suggest that high dietary GI and high carbohydrate intake from high GI foods are associated with increased risk of colorectal cancer.

    Background A recent Genome-Wide Association Study (GWAS) of prostate cancer in a Japanese population identified five novel regions not previously discovered in other ethnicities. In this study, we attempt to replicate these five loci in a series of nested prostate cancer case-control studies of European ancestry. Methods We genotyped five SNPs: rs13385191 (chromosome 2p24), rs12653946 (5p15), rs1983891 (6p21), rs339331 (6p22) and rs9600079 (13q22), in 7,956 prostate cancer cases and 8,148 controls from a series of nested case-control studies within the NCI Breast and Prostate Cancer Cohort Consortium (BPC3). We tested each SNP for association with prostate cancer risk and assessed if associations differed with respect to disease severity and age of onset. Results Four SNPs (rs13385191, rs12653946, rs1983891 and rs339331) were significantly associated with prostate cancer risk (p-values ranging from 0.01 to 1.1×10-5). Allele frequencies and odds ratios were overall lower in our population of European descent compared to the discovery Asian population. SNP rs13385191 (C2orf43) was only associated with low-stage disease (p=0.009, case-only test). No other SNP showed association with disease severity or age of onset. We did not replicate the 13q22 SNP, rs9600079 (p=0.62). Conclusions Four SNPs associated with prostate cancer risk in an Asian population are also associated with prostate cancer risk in men of European descent. Impact This study illustrates the importance of evaluation of prostate cancer risk markers across ethnic groups. PMID:22056501

    Full Text Available While the risk of ovarian cancer clearly reduces with each full-term pregnancy, the effect of incomplete pregnancies is unclear. We investigated whether incomplete pregnancies (miscarriages and induced abortions are associated with risk of epithelial ovarian cancer. This observational study was carried out in female participants of the European Prospective Investigation into Cancer and Nutrition (EPIC. A total of 274,442 women were followed from 1992 until 2010. The baseline questionnaire elicited information on miscarriages and induced abortions, reproductive history, and lifestyle-related factors. During a median follow-up of 11.5 years, 1,035 women were diagnosed with incident epithelial ovarian cancer. Despite the lack of an overall association (ever vs. never, risk of ovarian cancer was higher among women with multiple incomplete pregnancies (HR(≥4vs.0: 1.74, 95% CI: 1.20-2.70; number of cases in this category: n = 23. This association was particularly evident for multiple miscarriages (HR(≥4vs.0: 1.99, 95% CI: 1.06-3.73; number of cases in this category: n = 10, with no significant association for multiple induced abortions (HR(≥4vs.0: 1.46, 95% CI: 0.68-3.14; number of cases in this category: n = 7. Our findings suggest that multiple miscarriages are associated with an increased risk of epithelial ovarian cancer, possibly through a shared cluster of etiological factors or a common underlying pathology. These findings should be interpreted with caution as this is the first study to show this association and given the small number of cases in the highest exposure categories.

    Failure of concrete after a period of years, less than the life expected for which it was designed, may be caused by the environment to which it has been exposed or by a variety of internal causes. The incorporation of supplementary materials has at the Portland cement the purpose of improving the concrete microstructure and also of influence the resistance of concrete to environmental attacks. Different mineral by-products as ground granulated blast furnaces slag (GGBS), silica fume (SF), meta kaolin (MK), fly ash (FA) and other products have been used as supplementary cementing materials. This paper is about the behavior of concrete in the presence of mineral additions. Compared to Portland cements, blended cements show lower heat of hydration, lower permeability, greater resistance to sulphates and sea water. These blended cements find the best application when requirements of durability are regarded as a priority specially on high performance concrete: (Author) 11 refs.

    AIM:To study the epidemiologic indicators of uptake and characteristic colonoscopic findings in the Croatian National Colorectal Cancer Screening Program.METHODS:Colorectal cancer (CRC) was the second leading cause of cancer mortality in men (n =1063,49.77/100 000),as well as women (n =803,34.89/100 000) in Croatia in 2009.The Croatian National CRC Screening Program was established by the Ministry of Health and Social Welfare,and its implementation started in September,2007.The coordinators were recruited in each county institute of public health with an obligation to provide fecal occult blood testing (FOBT) to the participants,followed by colonoscopy in all positive cases.The FOBT was performed by hypersensitive guaiac-based Hemognost card test (Biognost,Zagreb).The test and short questionnaire were delivered to the home addresses of all citizens aged 50-74years consecutively during a 3-year period.Each participant was required to complete the questionnaire and send it together with the stool specimen on three test cards back to the institute for further analysis.About 4% FOBT positive cases are expected in normal risk populations.A descriptive analysis was performed.RESULTS:A total of 1 056 694 individuals (born between 1933-1945 and 1952-1957) were invited to screening by the end of September 2011.In total,210 239 (19.9%) persons returned the envelope with a completed questionnaire,and 181 102 of them returned it with a correctly placed stool specimen on FOBT cards.Until now,12 477 (6.9%),FOBT-positive patients have been found,which is at the upper limit of the expected values in European Guidelines for Quality Assurance in CRC Screening and Diagnosis [European Union (EU) Guidelines].Colonoscopy was performed in 8541 cases (uptake 66%).Screening has identified CRC in 472 patients (5.5% of colonoscopied,3.8% of FOBT-positive,and 0.26% of all screened individuals).This is also in the expected range according to EU Guidelines.Polyps were found and

    Full Text Available Putao Cen, Eric D Tetzlaff, Jaffer A AjaniDepartment of Gastrointestinal Medical Oncology in the Division of Cancer Medicine at the University of Texas MD Anderson Cancer Center, Houston, TX, USABackground: Capecitabine, an orally administered fluoropyrimidines, is widely used in the treatment of multiple malignancies. It has been extensively evaluated in patients with gastroesophageal carcinoma. Since recent reviews have discussed phase I/II trials (Cancer 107:221–231, 2006; Drugs 67:601–610, 2007, we focus on the impact of the results of the most current phase III trials using capectiabine in the treatment of advanced gastroesophageal cancers, primarily in the first-line setting.Methods: To find published phase III trials, Medline was searched for English-language clinical trials published from 1996 through June 2007 along with relevant abstracts presented at the American Society of Clinical Oncology, and meetings of the European Cancer Conference and European Society of Medical Oncology. Only representative trials were chosen for this manuscript.Results: The most frequently investigated combinations are capecitabine with taxanes, platinols, and camptothecins. Recent results of a large phase III trial (REAL-2 in untreated patients with gastroesophageal cancer suggest that capecitabine is a non-inferior substitute for intravenous 5-fluorouracil. These results of REAL-2 trial are substantiated by a smaller phase III trial. Previous analysis of multiple trials had suggested that capecitabine, when combined in doses lower than 1250 mg/m2 twice daily, consistently resulted in lower frequency of Grade 3 or 4 toxic effects.Conclusions: Capecitabine provides much needed convenience to patients with gastroesophageal cancer. The recent data derived from two phase III trials confirm that capecitabine is a suitable substitute for intravenous 5-fluorouracil in patients whose swallowing is not greatly affected. Capecitabine remains a subject of further

    Purpose: To assess local control and survival rates in patients with muscle-invasive bladder cancer treated with external-beam radiotherapy and to investigate prognostic factors. Patients and methods: Between 1997 and 2007, 75 patients (male, n = 58; female, n = 17, median age, 74.2 years) with localized transitional cell carcinoma of the bladder (T2, n = 34; T3, n = 32; T4, n = 9) not suitable for radical surgery due to advanced age, comorbidity or inoperability underwent external-beam radiotherapy without simultaneous chemotherapy at the University Clinic of Therapeutic Radiology and Oncology, Medical University of Graz, Austria. A conformal four-field technique was used in all patients to treat the tumor and regional lymph nodes with single daily fractions of 1.8-2 Gy to a total dose of 50-50.4 Gy, followed by a cone-down to encompass the empty bladder which was boosted to 70-70.4 Gy. All patients had undergone transurethral tumor resection prior to radiotherapy which was macroscopically incomplete in 62 patients. Results: Complete response was achieved in 65% of patients. Actuarial 3-year local control and metastases-free survival rates were 52.5% and 63.7%, 3-year local recurrence-free survival rate in complete responders was 71%. In univariate analysis, hydronephrosis, lymph vessel invasion, and macroscopic residual tumor were significantly predictive of disease progression. Hydronephrosis and lymph vessel invasion were also associated with a higher risk of local recurrence. The actuarial 3-year progression-free and overall survival rates were 40.1% and 56.9%, respectively. Conclusion: Radiotherapy is an effective treatment option in terms of local control and survival even in elderly patients with locally advanced bladder cancer not suitable for cystectomy. (orig.)

    Bernatzky et al. recently published a study on the prescribing practices of general practitioners in Austria with respect to the prescribing of opioids in cancer patients. The aim of the study was to assess the adequately of pain therapy and the resulting quality of life in chronic cancer patients. A representative sample of patients was taken from the Carinthian tumor register. These patient were sent a questionnaire alone with an explanatory letter and at a later date a reminder letter by mail. Of the 1.895 returned questionnaires 665 (35%) were completed. In this study only the data of the 429 patients who indicated that they experienced pain were processed. More than one fifth of the patients complained of a poor or a very poor quality of life and 80% of the patients were limited in their activities of daily living by pain. There are still many prejudices and informational gaps with respect to the effects of morphine. The main focus of treatment was medication therapy and was generally carried out by the family physician. The satisfaction with pain therapy was at best moderate. This is insofar of importance, as the satisfaction with pain therapy has a massive impact on the quality of life. More extensive information and education are required with respect to the various options and possibilities of pain control. Explanations of the mode of action and side-effects of pain medication in order to deal with the prejudices. Earlier and more focused use of pain therapy (long duration of pain), and use of coping aids for activities of daily living (limited through pain) and a broadening of the spectrum of treatment are all necessary. Patient satisfaction with pain therapy should be the main focus, as this is the deciding factor in terms of the quality of life.

  18. Inhibition of autophagic flux by salinomycin results in anti-cancer effect in hepatocellular carcinoma cells.

    Johannes Klose

    Full Text Available Salinomycin raised hope to be effective in anti-cancer therapies due to its capability to overcome apoptosis-resistance in several types of cancer cells. Recently, its effectiveness against human hepatocellular carcinoma (HCC cells both in vitro and in vivo was demonstrated. However, the mechanism of action remained unclear. Latest studies implicated interference with the degradation pathway of autophagy. This study aimed to determine the impact of Salinomycin on HCC-autophagy and whether primary human hepatocytes (PHH likewise are affected. Following exposure of HCC cell lines HepG2 and Huh7 to varying concentrations of Salinomycin (0-10 µM, comprehensive analysis of autophagic activity using western-blotting and flow-cytometry was performed. Drug effects were analyzed in the settings of autophagy stimulation by starvation or PP242-treatment and correlated with cell viability, proliferation, apoptosis induction, mitochondrial mass accumulation and reactive oxygen species (ROS formation. Impact on apoptosis induction and cell function of PHH was analyzed. Constitutive and stimulated autophagic activities both were effectively suppressed in HCC by Salinomycin. This inhibition was associated with dysfunctional mitochondria accumulation, increased apoptosis and decreased proliferation and cell viability. Effects of Salinomycin were dose and time dependent and could readily be replicated by pharmacological and genetic inhibition of HCC-autophagy alone. Salinomycin exposure to PHH resulted in transient impairment of synthesis function and cell viability without apoptosis induction. In conclusion, our data suggest that Salinomycin suppresses late stages of HCC-autophagy, leading to impaired recycling and accumulation of dysfunctional mitochondria with increased ROS-production all of which are associated with induction of apoptosis.

    Aims Epidermal growth factor receptor (EGFR) gene copy number evaluated by fluorescence in situ hybridisation (FISH) can discriminate among KRAS wild-type patients those with better outcome to EGFR-targeted therapy in metastatic colorectal cancer, further enhancing selection of patients. Nevertheless, enumeration of gene copies is challenging and the lack of analytical standardisation has limited incorporation of the test into the clinical practice. We therefore assessed EGFR FISH interlaboratory consensus among five molecular diagnostic reference centres. Methods A set of 12 colorectal cancer samples circulated among laboratories, and samples were scored according to commonly agreed guidelines. Reproducibility was quantified using the standard error of measurement (SEM). Results A SEM of 0.865 and a within-subject coefficient of variation (WSCV) of 26.8% for mean EGFR gene/nuclei and a SEM of 0.235 and a WSCV of 19.4% for the mean EGFR gene/CEP7 ratio were observed. Measurement of the fraction of cells displaying chromosome 7 polysomy showed WSCV of 46.6%, 34.0% and 51.0% for percentage of cells displaying ≤2, ≥3 and ≥4 EGFR signals, respectively. Among different slides of the same specimen, the WSCV was 6.1% for mean EGFR gene/nuclei and 3.9% for mean of EGFR gene/CEP7 ratios. Conclusions Molecular diagnosis of EGFR gene copy number by FISH varied largely among pathology centres, with fluctuations covering the whole range of proposed cut-offs of predictive usefulness from literature. Definition of a detailed scoring system and implementation of comprehensive training programmes for laboratories are therefore necessary before including the test into clinical practice.

    Background: Androgens are key regulators of prostate gland maintenance and prostate cancer growth, and androgen deprivation therapy has been the mainstay of treatment for advanced prostate cancer for many years. A long-standing hypothesis has been that inherited variation in the androgen receptor (AR) gene plays a role in prostate cancer initiation. However, studies to date have been inconclusive and often suffered from small sample sizes. Objective and Methods: We investigated the association of AR sequence variants with circulating sex hormone levels and prostate cancer risk in 6058 prostate cancer cases and 6725 controls of Caucasian origin within the Breast and Prostate Cancer Cohort Consortium. We genotyped a highly polymorphic CAG microsatellite in exon 1 and six haplotype tagging single nucleotide polymorphisms and tested each genetic variant for association with prostate cancer risk and with sex steroid levels. Results: We observed no association between AR genetic variants and prostate cancer risk. However, there was a strong association between longer CAG repeats and higher levels of testosterone (P = 4.73 × 10−5) and estradiol (P = 0.0002), although the amount of variance explained was small (0.4 and 0.7%, respectively). Conclusions: This study is the largest to date investigating AR sequence variants, sex steroid levels, and prostate cancer risk. Although we observed no association between AR sequence variants and prostate cancer risk, our results support earlier findings of a relation between the number of CAG repeats and circulating levels of testosterone and estradiol.

    A number of epidemiological studies have examined the association between use of dairy products and risk of ovarian cancer, but results are conflicting. Using data from a large Danish population-based case-control study we here further examined the association between dairy consumption, lactose, and calcium and risk of overall ovarian cancer and histological types of ovarian cancer. In the period 1995-1999 we included 554 women with epithelial ovarian cancer and 1554 randomly selected age-matched controls (35-79 years). All women participated in a detailed personal interview that included questions about dairy consumption. Data were analysed using multiple logistic regression models. Total dairy intake was associated with ovarian cancer risk (OR = 1.11; 95% CI: 1.07-1.15 per 100 ml/day). The association was strongest for milk [OR = 1.14; 95% CI: 1.03-1.27 per glass (200 ml)/day], soured milk products [OR = 1.49; 95% CI: 1.22-1.81 per portion (250 ml)/day] and yoghurt [OR = 1.65; 95% CI: 1.22-2.23 per portion (250 ml)/day]. In contrast, intake of cheese was associated with a decreased risk [OR = 0.70; 95% CI: 0.55-0.89 for > 1 portion (100 ml)/day compared with no intake]. Intake of lactose, but not calcium, was also associated with an increased ovarian cancer risk (OR = 1.24; 95% CI: 1.10-1.40 per 10 g of lactose/day). Similar risk patterns were observed for the different histological types of ovarian cancer, indicating virtually identical aetiologies with regard to dairy intake, lactose, and calcium. Our results indicate that intake of dairy products is associated with a modest increased risk of ovarian cancer. In addition, ovarian cancer development was associated with lactose intake.

    Background One of the goals of personalized medicine is to generate individual risk profiles that could identify individuals in the population that exhibit high risk. The discovery of more than two-dozen independent SNP markers in prostate cancer has raised the possibility for such risk stratification. In this study, we evaluated the discriminative and predictive ability for prostate cancer risk models incorporating 25 common prostate cancer genetic markers, family history of prostate cancer and age. Methods We fit a series of risk models and estimated their performance in 7,509 prostate cancer cases and 7,652 controls within the NCI Breast and Prostate Cancer Cohort Consortium (BPC3). We also calculated absolute risks based on SEER incidence data. Results The best risk model (C-statistic=0.642) included individual genetic markers and family history of prostate cancer. We observed a decreasing trend in discriminative ability with advancing age (P=0.009), with highest accuracy in men younger than 60 years (C-statistic=0.679). The absolute ten-year risk for 50-year old men with a family history ranged from 1.6% (10th percentile of genetic risk) to 6.7% (90th percentile of genetic risk). For men without family history, the risk ranged from 0.8% (10th percentile) to 3.4% (90th percentile). Conclusions Our results indicate that incorporating genetic information and family history in prostate cancer risk models can be particularly useful for identifying younger men that might benefit from PSA screening. Impact Although adding genetic risk markers improves model performance, the clinical utility of these genetic risk models is limited. PMID:22237985

  5. Impact of supplementary feeding on reproductive success of white storks.

    Full Text Available European white stork (Ciconia ciconia populations have been object to several conservation measures such as reintroduction programs, habitat improvement or supplementary feeding in the last decades. Although recent white stork censuses revealed an upward trend of most of the western populations, evaluations of the relative importance of certain conservation measures are still scarce or even lacking. In our study we analyzed the effect of supplementary feeding on the reproductive success of white storks in conjunction with other factors such as weather or nest site characteristics. We present data of 569 breeding events at 80 different nest sites located in variable distances to an artificial feeding site at Affenberg Salem (south-western Germany collected from 1990-2012. A multilevel Poisson regression revealed that in our study population (1 reproductive success was negatively affected by monthly precipitation in April, May and June, (2 pairs breeding on power poles had a lower reproductive success than pairs breeding on platforms or trees and (3 reproductive success was significantly higher in pairs breeding in close distance to the feeding site. The number of fledglings per nest decreased by 8% per kilometer distance to the feeding site. Our data suggest that supplementary feeding increases fledgling populations which may be a tool to attenuate population losses caused by factors such as habitat deterioration or unfavorable conditions in wintering habitats.

    Background Resumption of menstrual cycles is one of the indicators for restoration of reproductive capability in postpartum women. However, menstruation does not necessarily mean that ovulation has taken place. The aim of this study was to investigate the relation of supplementary feeding to return of menstruation and ovulation after delivery.Methods A questionnaire was used to obtain data from 101 breastfeeding mothers. The following elements were analyzed: age, education level, breastfeeding practice, time of return of menstruation, contraceptive practice, and starting time of supplementary feeding during the lactation at intervals of 6 weeks to 18 months after delivery. The ovulation was continuously monitored by ultrasonography and basal body temperature (BBT) measurement.Results By ultrasonography, 53 of the 101 women (52.5%) had the first ovulation (follicle >1.8 cm in diameter)within 154 days after delivery on average, among whom 11 (10.9%, 11/101) had restoration of ovulation within 4 months and 42 (41.6%, 42/101) had it after 4 months. In women with follicles >1.8 cm in diameter (n=53), the menstruation resumed (138±84) days after delivery, and the supplementary feeding was started at (4.0±1.1) months, which were significantly earlier than those in the women with follicular diameter <1.7 cm (n=48; (293±88) days, (5.1±1.3) months; t=9.003,P<0.01 and t=4.566, P<0.01). In the women with follicles >1.8 cm in diameter, 30 had return of menstruation before the end of ultrasonographic monitoring, while only 8 in the women with follicular diameter <1.7 cm had menstrual resumption at the same time (x2=16.91, P<0.01). The starting time of supplementary feeding was positively correlated with the time of the restoration of menstruation (n=100, r=0.4764, P<0.01) and first ovulation after delivery (n=53, r=0.5554, P<0.01).In this series, no woman had pregnancy within 18 months postpartum.Conclusion Supplementary feeding can affect the restoration

    1997-01-01

    Full Text Available We have introduced two endoscopic treatments for early gastric cancer: endoscopic mucosal resection using a cap-fitted panendoscope (EMRC, and endoscopic laser therapy using a Nd-YAG laser. Thirty-two patients (34 lesions with gastric cancer were treated by Nd-YAG laser; including 23 initial-therapy cases (25 lesions and 9 second-therapy cases representing failures of endoscopic mucosal resection or endoscopic ethanol injection. Endoscopic laser therapy was performed safely without complication in all patients. Three patients had residual cancer, and 2 of these required surgery. Six patients died from other disease. Endoscopic laser therapy can remove early gastric cancer even when the lesion has ulceration or submucosal invasion, and has a powerful hemostatic effect. It is a safe and effective treatment for early gastric cancer.

    Cholelithiasis and cholecystectomy have been proposed as risk factors for liver cancer, but findings have been inconsistent. We assessed this association using data from the Shanghai Women's and Men's Health Studies. History of cholelithiasis and cholecystectomy were reported at baseline and follow-up interviews, and liver cancer diagnoses were ascertained from the Shanghai Cancer Registry and Vital Statistics Unit. Adjusted hazard ratios (aHRs) and 95% CIs were calculated after adjustment for potential confounders. A history of cholelithiasis and cholecystectomy was reported by 9.5% and 3.6% of participants at baseline, respectively. After a total of 859,882 person-years of follow-up for women and 391,093 for men, incident liver cancer was detected in 160 women and 252 men. A positive association was observed between a history of cholelithiasis or cholecystectomy and liver cancer in men (aHR 1.46; 95% CI 1.02 to 2.07) and women (aHR 1.55; 95% CI 1.06 to 2.26). Similar results were observed for cholelithiasis only, but cholecystectomy did not reach statistical significance. There was no strong evidence for detection bias of liver cancer due to cholelithiasis or cholecystectomy. Our study suggests that cholelithiasis and possibly cholecystectomy may increase the risk of liver cancer.

    Some studies suggest that periodontal diseases increase the risk of oral cancer, but contradictory results also exist. Inadequate control of confounders, including life course exposures, may have influenced prior findings. We estimate the extent to which high levels of periodontal diseases, measured by gingival inflammation and recession, are associated with oral cancer risk using a comprehensive subset of potential confounders and applying a stringent adjustment approach. In a hospital-based case-control study, incident oral cancer cases (N = 350) were recruited from two major referral hospitals in Kerala, South India, from 2008 to 2012. Controls (N = 371), frequency-matched by age and sex, were recruited from clinics at the same hospitals. Structured interviews collected information on several domains of exposure via a detailed life course questionnaire. Periodontal diseases, as measured by gingival inflammation and gingival recession, were evaluated visually by qualified dentists following a detailed protocol. The relationship between periodontal diseases and oral cancer risk was assessed by unconditional logistic regression using a stringent empirical selection of potential confounders corresponding to a 1% change-in-estimates. Generalized gingival recession was significantly associated with oral cancer risk (Odds Ratio = 1.83, 95% Confidence Interval: 1.10-3.04). No significant association was observed between gingival inflammation and oral cancer. Our findings support the hypothesis that high levels of periodontal diseases increase the risk of oral cancer. © 2016 UICC.

    The relationship between body size and prostate cancer risk, and in particular risk by tumour characteristics, is not clear because most studies have not differentiated between high-grade or advanced stage tumours, but rather have assessed risk with a combined category of aggressive disease. We investigated the association of height and adiposity with incidence of and death from prostate cancer in 141,896 men in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. Multivariable-adjusted Cox proportional hazards models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). After an average of 13.9 years of follow-up, there were 7024 incident prostate cancers and 934 prostate cancer deaths. Height was not associated with total prostate cancer risk. Subgroup analyses showed heterogeneity in the association with height by tumour grade (P heterogeneity = 0.002), with a positive association with risk for high-grade but not low-intermediate-grade disease (HR for high-grade disease tallest versus shortest fifth of height, 1.54; 95% CI, 1.18-2.03). Greater height was also associated with a higher risk for prostate cancer death (HR = 1.43, 1.14-1.80). Body mass index (BMI) was significantly inversely associated with total prostate cancer, but there was evidence of heterogeneity by tumour grade (P heterogeneity = 0.01; HR = 0.89, 0.79-0.99 for low-intermediate grade and HR = 1.32, 1.01-1.72 for high-grade prostate cancer) and stage (P heterogeneity = 0.01; HR = 0.86, 0.75-0.99 for localised stage and HR = 1.11, 0.92-1.33 for advanced stage). BMI was positively associated with prostate cancer death (HR = 1.35, 1.09-1.68). The results for waist circumference were generally similar to those for BMI, but the associations were slightly stronger for high-grade (HR = 1.43, 1.07-1.92) and fatal prostate cancer (HR = 1.55, 1.23-1.96). The findings from this large prospective study show that

    In 2007, the World Cancer Research Fund (WCRF) and American Institute for Cancer Research (AICR) published eight recommendations regarding body weight, physical activity, and dietary behaviors aimed at reducing cancer incidence worldwide. In this paper, we assess whether meeting the WCRF/AICR recommendations is associated with lower colorectal cancer (CRC) incidence; evaluate whether particular recommendations are most strongly associated with lower CRC incidence; and assess whether associations differ by sex. We operationalized six of the recommendations (related to body weight, physical activity, energy density, plant foods, red and processed meat, and alcohol) and examined their association with CRC incidence over 7.6 years of follow-up in the prospective VITamins And Lifestyle Study cohort. Participants included 66,920 adults aged 50-76 years at baseline (2000-2002) with no history of CRC and with complete data for the recommendations evaluated. Incident colorectal cancers (n = 546) were tracked through 2009. Compared with meeting no recommendations, meeting 1-3 recommendations was associated with 34-45 % lower CRC incidence, and meeting 4-6 was associated with 58 % lower incidence (95 % CI 34 %, 74 %) in fully adjusted analyses. The recommendations most strongly associated with lower CRC risk for women were related to body fatness and red and processed meat, while for men these were alcohol intake and red and processed meat. Differences by sex were statistically significant (p alcohol. Meeting the WCRF/AICR recommendations, particularly those related to alcohol, body weight, and red and processed meat, could substantially reduce CRC incidence; however, associations differ by sex.

  8. Supplementary Material for: Promoter hypermethylation of HS3ST2, SEPTIN9 and SLIT2 combined with FGFR3 mutations as a sensitive/specific urinary assay for diagnosis and surveillance in patients with low or high-risk non-muscle-invasive bladder cancer

    2016-01-01

    Abstract Background Non-muscle-invasive bladder cancer (NMIBC) is a high incidence form of bladder cancer (BCa), where genetic and epigenetic alterations occur frequently. We assessed the performance of associating a FGFR3 mutation assay and a DNA methylation analysis to improve bladder cancer detection and to predict disease recurrence of NMIBC patients. Methods We used allele specific PCR to determine the FGFR3 mutation status for R248C, S249C, G372C, and Y375C. We preselected 18 candidate genes reported in the literature as being hypermethylated in cancer and measured their methylation levels by quantitative multiplex-methylation specific PCR. We selected HS3ST2, SLIT2 and SEPTIN9 as the most discriminative between control and NMIBC patients and we assayed these markers on urine DNA from a diagnostic study consisting of 167 NMIBC and 105 controls and a follow-up study consisting of 158 NMIBC at diagnosis time’s and 425 at follow-up time. ROC analysis was performed to evaluate the diagnostic accuracy of each assay alone and in combination. Results For Diagnosis: Using a logistic regression analysis with a model consisting of the 3 markers’ methylation values, FGFR3 status, age and known smoker status at the diagnosis time we obtained sensitivity/specificity of 97.6 %/84.8 % and an optimism-corrected AUC of 0.96. With an estimated BCa prevalence of 12.1 % in a hematuria cohort, this corresponds to a negative predictive value (NPV) of 99.6 %. For Follow-up: Using a logistic regression with FGFR3 mutation and the CMI at two time points (beginning of the follow-up and current time point), we got sensitivity/specificity/NPV of 90.3 %/65.1 %/97.0 % and a corrected AUC of 0.84. We also tested a thresholding algorithm with FGFR3 mutation and the two time points as described above, obtaining sensitivity/specificity/NPV values of, respectively, 94.5 %/75.9 %/98.5 % and an AUC of 0.82. Conclusions We showed that combined analysis of FGFR3 mutation and DNA

    Latinas have the highest rates of cervical cancer in the United States and the second highest rate of cervical cancer mortality. One factor in the disparity is the relatively low rate of screening for cervical cancer in this population. Eligible women who were out of adherence with cervical cancer screening (>3 years since their last Papanicolaou [Pap] test) were identified via medical record review by a federally qualified local health center. The effects of a low-intensity intervention (video delivered to participants' homes; n = 150) and a high-intensity intervention (video plus a home-based educational session; n = 146) on cervical cancer screening uptake in comparison with a control arm (usual care; n = 147) were investigated. A cost-effectiveness analysis of the interventions was conducted: all intervention costs were calculated, and the incremental cost-effectiveness ratio was computed. Finally, women with positive Pap tests were provided navigation by a community health educator to ensure that they received follow-up care. A total of 443 Latinas participated. Seven months after randomization, significantly more women in the high-intensity arm received a Pap test (53.4%) in comparison with the low-intensity arm (38.7%; P cancer; these women received navigation for follow-up care. A culturally appropriate, in-home, promotora-led educational intervention was successful in increasing cervical cancer screening among Latinas.

  10. Glass cullet as a new supplementary cementitious material (SCM)

    Science.gov (United States)

    Mirzahosseini, Mohammadreza

    Finely ground glass has the potential for pozzolanic reactivity and can serve as a supplementary cementitious material (SCM). Glass reaction kinetics depends on both temperature and glass composition. Uniform composition, amorphous nature, and high silica content of glass make ground glass an ideal material for studying the effects of glass type and particle size on reactivity at different temperature. This study focuses on how three narrow size ranges of clear and green glass cullet, 63--75 mum, 25--38 mum, and smaller than 25 mum, as well as combination of glass types and particle sizes affects the microstructure and performance properties of cementitious systems containing glass cullet as a SCM. Isothermal calorimetry, chemical shrinkage, thermogravimetric analysis (TGA), quantitative analysis of X-ray diffraction (XRD), and analysis of scanning electron microscope (SEM) images in backscattered (BS) mode were used to quantify the cement reaction kinetics and microstructure. Additionally, compressive strength and water sorptivity experiments were performed on mortar samples to correlate reactivity of cementitious materials containing glass to the performance of cementitious mixtures. A recently-developed modeling platform called "muic the model" was used to simulated pozzolanic reactivity of single type and fraction size and combined types and particle sizes of finely ground glass. Results showed that ground glass exhibits pozzolanic properties, especially when particles of clear and green glass below 25 mum and their combination were used at elevated temperatures, reflecting that glass cullet is a temperature-sensitive SCM. Moreover, glass composition was seen to have a large impact on reactivity. In this study, green glass showed higher reactivity than clear glass. Results also revealed that the simultaneous effect of sizes and types of glass cullet (surface area) on the degree of hydration of glass particles can be accounted for through a linear addition

    Between January 1983 and December 1988, 218 female patients with known breast cancer and positive axillary nodes were treated with adjuvant radiotherapy and chemotherapy following radical mastectomy. Treatment results were retrospectively analysed at the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University of College of Medicine. The patients were classified into 3 groups; group 1 included 80 patients treated with adjuvant chemotherapy alone; in group 2, 52 patients treated with radiotherapy alone; and in group 3, 86 patients treated with combined chemo-radiotherapy. The mean age was 44 years and ranged from 27 to 70. The median follow-up time was 51 months. Seven-year relapse free and overall survival rates were 56% and 67%; in group 1, 50% and 56%; in group 2, 51% and 65%; and in group 3, 62% and 75% respectively. This difference was not statistically significant(p<0.05). The loco-regional failure rates were 13% and distant failure rates were 33%. There was less risk of loco-regional failure in group 2 and 3 which included radiotherapy (.0<0.05). But there was no significant y difference in the rates of distant failure(p>0.05). By univariate analysis, the only significant prognostic factor affecting relapse-free survival was the percentage of positive axillary nodes; and the overall survival significantly correlated with the primary tumor size, the number or percentage of positive axillary nodes, and stage. But in multivariate analysis, the only significant prognostic factor was treatment modality. By univariate analysis of prognostic factors affecting the rates of overall failure and distant failure, the significant prognostic factors was the percentage of positive axillary nodes; and the risk of the loco-regional failure significantly correlated with the treatment modality. In conclusion, these results suggest a potential for decreasing the risk of loco-regional failure with the addition of postoperative radiotherapy to chemotherapy in the

    Chronic inflammation has been hypothesized to increase prostate cancer risk. Prostaglandin-endoperoxide synthase 2 (PTGS2) encodes the proinflammatory cyclooxygenase 2 enzyme believed to be the rate-limiting step in the synthesis of prostaglandins, important mediators of inflammation. We investigated associations between PTGS2 polymorphisms and prostate cancer risk among 2321 prostate cancer cases and 2560 controls in two large case-control studies nested within the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial and the Cancer Prevention Study II Nutrition Cohort. Five single nucleotide polymorphisms (SNPs) (rs5277, rs20432, rs4648276, rs5275 and rs689470) were examined in SNP and haplotype analyses (five SNPs in PLCO and four SNPs in the Nutrition Cohort). In PLCO, the Ex10 +837 T>C marker (rs5275) was initially associated with prostate cancer risk (P-trend = 0.02) but became non-significant after adjustment for multiple comparisons (P = 0.08); this SNP showed no association with prostate cancer risk in the Nutrition Cohort (P-trend = 0.54) or in an analysis pooling the two cohorts (P-trend = 0.20). No other SNP was associated with prostate cancer risk in PLCO or the Nutrition Cohort individually or combined. Haplotype analyses suggested an association between PTGS2 variants in PLCO alone (global P = 0.007), but not in the Nutrition Cohort (global P = 0.78) or pooled analysis (global P = 0.18). In conclusion, despite the potential importance of inflammation in prostate carcinogenesis, results from our large study of five PTGS2 SNPs does not support a strong association between PTGS2 variants and prostate cancer risk in non-Hispanic white men.

    We clinically evaluated 12 patients with advanced superficial esophageal cancer who had undergone chemoradiotherapy. A retrospective analysis was performed between October 1992 and December 1998 on 12 patients with M1 metastasis in lymph nodes or direct invasion of enlarged lymph nodes (A3) to adjacent structures. Combined treatment with radiotherapy and chemotherapy was applied to all patients. High-dose cisplatin (CDDP) and 5-fluorouracil (5FU) were administered to five patients, low-dose CDDP and 5-FU to five patients, and others to two patients. Ten patients were treated by external irradiation alone, and two patients were treated by external and intracavitary irradiation. Of the 12 patients, the response of the primary tumor to this therapy resulted in 11 CRs (91.6%) and one PR, while the response of the largest metastatic lesion in lymph nodes in each patient resulted in three CRs (25%), four PRs (33.3%), and five NCs (41.6%). The 2-year survival rate of all patients was 51.9%, and MST was 28.9 months. The 2-year survival rates of the M1 and A3 patients were 60.0% and 41.7%, respectively. This study revealed that the present chemotherapy regimen is ineffective in treating metastatic lymph node lesions. Therefore, it will be necessary to evaluate the effectiveness of chemoradiotherapeutic agents from the perspective of their effects on metastatic lymph nodes. (author)

    Introduction: Thyroid cancer is the most common endocrine malignancy. The current gold standard for diagnosis, fine-needle aspiration (FNA) biopsy, yields 10-25% of indeterminate cytology results, leading to patients undergoing thyroidectomy for diagnosis. We assessed the technical potential of a miniaturized in vivo ESS (elastic light scattering spectroscopy) probe, built into an FNA needle assembly, to differentiate benign from malignant thyroid nodules. Methods: Under IRB approval, 15 patients in the endocrine clinic undergoing FNAB of a thyroid nodule had collection of ESS data using our novel miniaturized FNA probe. Using final surgical pathology as our gold standard, data post processing and visual inspection was completed. Results: 225 spectra were grouped and analyzed (120 benign, 30 malignant and 75 from indeterminate cytology). ESS probes demonstrated excellent reproducibility in use. Initial analysis of these preliminary data is promising, indicating distinction of spectral ESS features between malignant and benign conditions. Conclusion(s): An in vivo trial of an invasive miniaturized integrated ESS biopsy probe is acceptable to patients, and collection of ESS data is feasible and reliable. With development of a disease-specific algorithm, ESS could potentially be used as an in-situ real time intra-operative diagnostic tool or as a minimally invasive adjunct to conventional FNA cytology.

    Background Studies suggest that vitamin D status may be associated with prostate cancer risk, although the direction and strength of this association differs between experimental and observational studies. Genome-wide association studies have identified genetic variants associated with 25-hydroxyvitamin D (25(OH)D) status. We examined prostate cancer risk in relation to SNPs in four genes shown to predict circulating levels of 25(OH)D. Methods SNP markers localized to each of four genes (GC, CYP24A1, CYP2R1, and DHCR7) previously associated with 25(OH)D were genotyped in 10,018 cases and 11,052 controls from the NCI Breast and Prostate Cancer Cohort Consortium. Logistic regression was used to estimate the individual and cumulative association between genetic variants and risk of overall and aggressive prostate cancer. Results We observed a decreased risk of aggressive prostate cancer among men with the allele in rs6013897 near CYP24A1 associated with lower serum 25(OH)D (per A allele, OR=0.86, 95%CI=0.80–0.93, p-trend=0.0002), but an increased risk for non-aggressive disease (per a allele: OR=1.10, 95%CI=1.04–1.17, p-trend=0.002). Examination of a polygenic score of the four SNPs revealed statistically significantly lower risk of aggressive prostate cancer among men with a greater number of low vitamin D alleles (OR for 6–8 vs. 0–1 alleles = 0.66, 95% CI = 0.44 – 0.98; p-trend=0.003). Conclusions In this large, pooled analysis, genetic variants related to lower 25(OH)D were associated with a decreased risk of aggressive prostate cancer. Impact Our genetic findings do not support a protective association between loci known to influence vitamin D levels and prostate cancer risk. PMID:23377224

    The incidence of colorectal cancer has been increasing in many Asian countries including Malaysia during the past few decades. A physician recommendation has been shown to be a major factor that motivates patients to undergo screening. The present study objectives were to describe the practice of colorectal cancer screening by primary care providers in Malaysia and to determine the barriers for not following recommendations. In this cross sectional study involving 132 primary care providers from 44 Primary Care clinics in West Malaysia, self-administered questionnaires which consisted of demographic data, qualification, background on the primary care clinic, practices on colorectal cancer screening and barriers to colorectal cancer screening were distributed. A total of 116 primary care providers responded making a response rate of 87.9%. About 21% recommended faecal occult blood test (FOBT) in more than 50% of their patients who were eligible. The most common barrier was "unavailability of the test". The two most common patient factors are "patient in a hurry" and "poor patient awareness". This study indicates that colorectal cancer preventive activities among primary care providers are still poor in Malaysia. This may be related to the low availability of the test in the primary care setting and poor awareness and understanding of the importance of colorectal cancer screening among patients. More awareness programmes are required for the public. In addition, primary care providers should be kept abreast with the latest recommendations and policy makers need to improve colorectal cancer screening services in health clinics.

    The National Oncologic PET Registry prospectively assessed the impact of PET with (18)F-sodium fluoride (NaF PET) on intended management of Medicare patients with suspected or known osseous metastasis. We report our findings for cancers other than prostate and make selected comparisons to our previously reported prostate cancer cohort. Data were collected from both referring and interpreting physicians before and after NaF PET in patients (age ≥ 65 y) stratified for initial staging (IS; n = 570), for suspected first osseous metastasis (FOM; n = 1,814; breast, 781 [43%]; lung, 380 [21%]; and all other cancers, 653 [36%]), and for suspected progression of osseous metastasis (POM; n = 435). The dominant indication was bone pain. If NaF PET were unavailable, conventional bone scintigraphy would have been ordered in 85% of patients. In IS, 28% of patients had suspected or confirmed nonosseous metastasis. If neither conventional bone scintigraphy nor NaF PET were available, referring physicians would have ordered other advanced imaging more than 70% of the time rather than initiate treatment for suspected FOM (11%-16%) or POM (18%-22%). When intended management was classified as either treatment or nontreatment, the intended management change for each cancer type was highest in POM, lower in IS, and lowest in FOM. For suspected FOM, intended management change was lower in breast (24%), lung (36%), or other cancers (31%), compared with prostate cancer (44%) (P types. After normal/benign/equivocal PET results, 15% of breast, 30% lung, and 38% prostate cancer patients had treatment, likely reflecting differences in management of nonosseous disease. For patients with definite metastasis on NaF PET, nonprostate, compared with prostate, cancer patients had post-PET plans for more frequent biopsy, alternative imaging, chemotherapy, and radiotherapy. In the smaller IS and POM cohorts, differences among cancer types were not significant. Overall, NaF PET led to change in

    The World Health Organization recommends visual inspection with acetic acid (VIA) for cervical cancer screening in resource-limited settings. In Cameroon, we use digital cervicography (DC) to capture images of the cervix after VIA. This study evaluated interobserver agreement of DC results, compared DC with histopathologic results, and examined interobserver agreement among screening methods. Three observers, blinded to each other's interpretations, evaluated 540 DC photographs as follows: (1) negative/positive for acetowhite lesions or cancer and (2) assigned a presumptive diagnosis of histopathologic lesion grade in the 91 cases that had a histopathologic diagnosis. Observer A was the actual screening nurse; B, a reproductive health nurse; C, a gynecologic oncologist; and D, the histopathologic diagnosis. We compared inter-rater agreement of DC impressions among observers A, B, and C, and with D, with Cohen kappas. For interpretations of DC, (negative/positive) strengths of agreement of paired observers were the following: A/B, moderate [K, 0.54; 95% confidence interval (CI), 0.47-0.61], A/C, fair (K, 0.37; 95% CI, 0.29-0.44), and B/C, moderate (K, 0.45; 95% CI, 0.37-0.53). For presumptive pathologic grading, strengths of agreement for weighted Ks were as follows: A/B, moderate (K, 0.42; 95% CI, 0.28-0.56); A/C, fair (K, 0.33; 95% CI, 0.20-0.46); B/C, fair (K, 0.54; 95% CI, 0.40-0.67); A/D, moderate (K, 0.59; 95% CI, 0.45-0.74); B/D, moderate (K, 0.58; 95% CI, 0.46-0.70); and C/D, moderate (K, 0.50; 95% CI, 0.37-0.63). Interobserver agreement of DC interpretations was mostly moderate among the 3 observers, between them and histopathology, and comparable to that of other visual-based screening methods, i.e., VIA, cytology, or colposcopy.

    Health-related quality of life (HRQOL) in differentiated thyroid cancer (DTC) research has so far received little attention and available results are conflicting. We studied the HRQOL of radioiodine-naive DTC patients in comparison with the general population (GP), investigated the course of HRQOL up to 30 months after radioiodine remnant ablation (RAA) and sought to identify patient characteristics associated with HRQOL. We analysed data from routine HRQOL monitoring at a nuclear medicine department. Between 2005 and 2013, a total of 439 thyroid cancer patients (all histologies) completed the EORTC Quality of Life Questionnaire Core-30 (QLQ-C30) at least once during their treatment at the department. We compared patients' baseline HRQOL scores before RAA with scores from age-matched and sex-matched controls from the Austrian GP. We then determined the course of HRQOL over the 30 months after RAA and assessed the impact of the following clinical variables on HRQOL: method of thyroid-stimulating hormone (TSH) stimulation, histology (papillary vs. follicular) and disease stage. A total of 284 patients (mean age 48.3 years, SD 15.0 years; 71.6 % women; 80.7 % papillary type) with a baseline HRQOL assessment before RAA were available. We found clinically meaningful differences in the detriment in patients on almost all domains. These were largest for fatigue (23 points) and role functioning (25 points). Data from 241 patients (mean age 48.6 years, SD 15.9 years; 68.9 % women; 76.3 % papillary type) were included in the longitudinal analysis. Investigating the course of HRQOL, a significant improvement over time was found for role and emotional functioning, fatigue, pain, and dyspnoea. A range of HRQOL scores were improved in patients with exogenous TSH stimulation, but some scores both in patients with exogenous TSH stimulation and in those followed for 30 months, especially fatigue and role functioning, did not reach levels in the GP sample. Our results show that

    Full Text Available Abstract Background EHR systems are widely used in hospitals and primary care centres but it is usually difficult to share information and to collect patient data for clinical research. This is partly due to the different proprietary information models and inconsistent data quality. Our objective was to provide a more flexible solution enabling the clinicians to define which data to be recorded and shared for both routine documentation and clinical studies. The data should be possible to reuse through a common set of variable definitions providing a consistent nomenclature and validation of data. Another objective was that the templates used for the data entry and presentation should be possible to use in combination with the existing EHR systems. Methods We have designed and developed a template based system (called Julius that was integrated with existing EHR systems. The system is driven by the medical domain knowledge defined by clinicians in the form of templates and variable definitions stored in a common data repository. The system architecture consists of three layers. The presentation layer is purely web-based, which facilitates integration with existing EHR products. The domain layer consists of the template design system, a variable/clinical concept definition system, the transformation and validation logic all implemented in Java. The data source layer utilizes an object relational mapping tool and a relational database. Results The Julius system has been implemented, tested and deployed to three health care units in Stockholm, Sweden. The initial responses from the pilot users were positive. The template system facilitates patient data collection in many ways. The experience of using the template system suggests that enabling the clinicians to be in control of the system, is a good way to add supplementary functionality to the present EHR systems. Conclusion The approach of the template system in combination with various local EHR

    Full Text Available Carbon dioxide (CO2 a major Green House Gas (GHG in the atmosphere, is believed to be largely responsible for global climate change through industrial emissions. The level of CO2 concentration has exponentially increased from about 280 ppm at the start of the industrial revolution to about 380 ppm to date. Although Kyoto protocol has bound industrialized nations to reduce green house gas emissions by 5.2% below 1990 levels around year 2008-2012, but violation continues. The cement industry is one of the major emitter of green house gases, particularly CO2 due to its energy intensive production process. It is estimated that approximately 1 tone of CO2 is released during the manufacturing of each tone of Portland cement. Most of CO2 emissions originate from burning fossil fuels and de-carbonization of limestone in a cement plant. During past several decades, the use of by-product materials in concrete, either as components of blended cements or as admixtures, has increased significantly. In this study, another alternate Supplementary Cementing Material (SCM, Laterite has been used with the objectives: to evaluate the performance of cement containing different percentages of laterite (5, 10, 15, 20, 25, and 30 %; to identify the optimum replacement percentage; and to investigate the effects of different concentrations of laterite on various properties of cement. For that purpose, laterite was tested: before blending (for elemental and mineralogical composition by using XRF, SEM and XRD: after blending (Elemental analysis using XRF, fineness test by using Blaine’s air permeability test and for particle size % on 45, 90 and 200 µ sieve, respectively; and after hydration (for mineralogical analysis using SEM. Furthermore, physical tests of manufactured cement, i.e., water consistency, setting time, Le-Chatlier-expansion and compressive strength were also evaluated and compared with limestone and fly-ash cement blends. The results show that with the

    Automated machine-reading biocuration systems typically use sentence-by-sentence information extraction to construct meaning representations for use by curators. This does not directly reflect the typical discourse structure used by scientists to construct an argument from the experimental data available within a article, and is therefore less likely to correspond to representations typically used in biomedical informatics systems (let alone to the mental models that scientists have). In this study, we develop Natural Language Processing methods to locate, extract, and classify the individual passages of text from articles' Results sections that refer to experimental data. In our domain of interest (molecular biology studies of cancer signal transduction pathways), individual articles may contain as many as 30 small-scale individual experiments describing a variety of findings, upon which authors base their overall research conclusions. Our system automatically classifies discourse segments in these texts into seven categories (fact, hypothesis, problem, goal, method, result, implication) with an F-score of 0.68. These segments describe the essential building blocks of scientific discourse to (i) provide context for each experiment, (ii) report experimental details and (iii) explain the data's meaning in context. We evaluate our system on text passages from articles that were curated in molecular biology databases (the Pathway Logic Datum repository, the Molecular Interaction MINT and INTACT databases) linking individual experiments in articles to the type of assay used (coprecipitation, phosphorylation, translocation etc.). We use supervised machine learning techniques on text passages containing unambiguous references to experiments to obtain baseline F1 scores of 0.59 for MINT, 0.71 for INTACT and 0.63 for Pathway Logic. Although preliminary, these results support the notion that targeting information extraction methods to experimental results could provide

    Poor oral hygiene has been proposed to contribute to head and neck cancer (HNC) risk, although causality and independency of some indicators are uncertain. This study investigates the relationship of five oral hygiene indicators with incident HNCs. In a pooled analysis of 8925 HNC cases and 12 527 controls from 13 studies participating in the International Head and Neck Cancer Epidemiology Consortium, comparable data on good oral hygiene indicators were harmonized. These included: no denture wear, no gum disease (or bleeding), <5 missing teeth, tooth brushing at least daily, and visiting a dentist ≥once a year. Logistic regression was used to estimate the effects of each oral hygiene indicator and cumulative score on HNC risk, adjusting for tobacco smoking and alcohol consumption. Inverse associations with any HNC, in the hypothesized direction, were observed for <5 missing teeth [odds ratio (OR) = 0.78; 95% confidence interval (CI) 0.74, 0.82], annual dentist visit (OR = 0.82; 95% CI 0.78, 0.87), daily tooth brushing (OR = 0.83, 95% CI 0.79, 0.88), and no gum disease (OR = 0.94; 95% CI 0.89, 0.99), and no association was observed for wearing dentures. These associations were relatively consistent across specific cancer sites, especially for tooth brushing and dentist visits. The population attributable fraction for ≤ 2 out of 5 good oral hygiene indicators was 8.9% (95% CI 3.3%, 14%) for oral cavity cancer. Good oral hygiene, as characterized by few missing teeth, annual dentist visits, and daily tooth brushing, may modestly reduce the risk of HNC. © The Author 2016.

    Purpose. - To assess the potential benefit of a boost in patients treated with whole brain irradiation by a conventional linear accelerator for lung cancer solitary brain metastasis. Patients and methods. - From 2002 to 2006, a retrospective analysis was carried out from 64 unselected consecutive patients with secondary brain metastasis from lung cancer, treated with whole brain irradiation without surgical resection. Thirty patients (47%) received a boost in their brain metastases. Three potential prognostic factors were studied: sex, RPA score and improvement of neurological symptoms after radiotherapy. An analysis was conducted to determine whether an additional dose may improve survival in the absence of surgical resection. Results. - The mean follow-up was 4.9 months. The median overall survival was 8.5 months (6.4 to 10.7 months). The total dose of radiotherapy was the only significant prognostic factor for overall survival. The median overall survival was 6.2 months for patients without additional radiation versus 11.2 months for patients receiving a boost dose (p = 0.011). Sex, RPA score and improvement of neurological symptoms after radiotherapy were not found as prognostic factors for overall survival. Conclusions. - Boost delivered after whole brain radiation therapy by a conventional particle accelerator may provide a benefit in selected patients, especially for centres that do not have radiotherapy techniques in stereotactic conditions. This warrants further prospective assessment. (authors)

    Healthcare accreditation is considered to be an essential quality improvement tool. However, its effectiveness has been critiqued. Twenty-four interviews were conducted with clinicians (five), nurses (six), managers (eight), and basic/translational researchers (five) from eight European cancer centres on changes observed from participating in a European cancer accreditation programme. Data were thematically analysed and verified with participants and checked against auditor's feedback. Four change categories emerged: (i) the growing importance of the nursing and supportive care field (role change). Nurses gained more autonomy/clarity on their daily duties. Importance was given to the hiring and training of supportive care personnel (ii) critical thinking on data integration (strategic change). Managers gained insight on how to integrate institutional level data (iii) improved processes within multidisciplinary team (MDT) meetings (procedural change). Clinical staff experienced improved communication between MDTs (iv) building trust (organisational change). Accreditation improved the centre's credibility with its own staff and externally with funders and patients. No motivational changes were perceived. Researchers perceived no changes. The auditor's feedback included changes in 13 areas: translational research, biobanks, clinical trials, patient privacy and satisfaction, cancer registries, clinical practice guidelines, patient education, screening, primary prevention, role of nurses, MDT, supportive care, and data integration. However, our study revealed that staff perceived changes only in the last four areas. Staff perceived changes in data integration, nursing and supportive care, and in certain clinical aspects. Accreditation programmes must pay attention to the needs of different stakeholder groups, track changes, and observe how/why change happens.

    The communication between medical students and cancer caregivers, and the problems they have experienced as well as the outcomes for their professional development before starting clinical practice was assessed in the context of a student research project. Data were collected by questionnaires or by 20 to 40-min long interviews with cancer caregivers. Their communications with physicians, hearing the bad news, and health service satisfaction were questioned. Therefore, the caregivers trusted the professional approach of their physician. However, they expected more empathic communication in the process of diagnosis and therapy. Development of empathy and trust-based communication between patients and physicians and enhancement of the quality of devoted time to cancer patients and caregivers may have an effect on the course of disease. Interviewer students mentioned that they developed communication skills about difficult clinical tasks and in delivering bad news face to face to cancer caregivers before starting their clinical education.

    This study examined the following: (1) relationships between religiosity-as measured by religious service attendance-and screening for breast, cervical, and colorectal cancers; (2) the potential mediating role of social support; and (3) the potential moderating effect of race/ethnicity. Statistical analyses showed that religiosity was associated with greater utilization of breast, cervical, and colorectal cancer screening. Social support fully mediated the relationship between religiosity and Pap screening, and partially mediated the relationship between religiosity and colorectal screening, but had no effect on the relationship between religiosity and mammography screening. Race/ethnicity moderated the relationship between religiosity and social support in the cervical cancer screening model, such that the positive association between religiosity and social support was stronger for non-Hispanic Blacks than it was for non-Hispanic Whites. These findings have implications for the role of social networks in health promotion and can inform cancer screening interventions in faith-based settings.

    The role of the radioguided occult lesion localisation (ROLL) technique in breast cancer has been increasing in recent years. One of the important drawbacks of such a technique is radiotracer spillage within the mammary gland that makes the precise lesion resection difficult, and this requires the use of a hook-wire collocation to reach the lesion. The possibility of obtaining an intraoperative image of the specimen could help to confirm whether the lesion is correctly removed. Some types of portable gamma cameras have been designed, but up to now, intraoperative use has been confined to surgery of parathyroid adenomas and sentinel lymph node location. The aim of the study was to value the usefulness of an intraoperative gamma camera to assess the resection of non-palpable breast lesions. The study involved 42 women diagnosed with non-palpable early breast cancer. Lymphoscintigraphy was performed on the day before surgery by injection of {sup 99m}Tc-labelled nanocolloid. During surgery a gamma probe was used to guide the surgeon, and afterwards images of the surgical bed and the tumoral specimen were acquired by means of a portable gamma camera, fitted with a pinhole collimator. A {sup 99m}Tc pointer was used to draw an outline image around the specimen. On lymphoscintigraphy, radiotracer was concentrated in 31 cases. During surgery, all lesions were removed. In the images acquired by the portable gamma camera, the lesion was centred inside the surgical specimen in 23 of 42 cases, non-centred in 15 and in contact in 4 cases. Congruence of 60% was found between the intraoperative images and the histopathological results. The posterior margin was the most frequently involved. The whole acquisition time for the tumoral specimen with its margins was 5 min at most. The use of portable gamma cameras in theatre is in an early phase. The short period of time required during the surgical procedure will allow the surgical team to improve this technique until it can replace

Patients with stage III or IV, nonmetastatic, measurable squamous cell carcinoma of the head and neck (SCCHN were eligible.Results: There were 18 males and two females. The median age was 61 years (range from 49 to 87 years old. Concurrent radiotherapy and cetuximab was used, in first line, in 17 patients with locally advanced disease; two patients with recurrent SCCHN, who were intolerant of Cisplatin-based regimens, were treated with radiotherapy combined with weekly cetuximab; and 1 patient received cetuximab and radiotherapy postoperatively. The median time of response was 10 months (range from 2 to 24 months. A partial response was observed in 11 cases; a complete response in nine cases. The occurrence of grade 2–3 skin toxicity was observed in 11 cases. Skin toxicity was clearly correlated with a better response and the duration of the response to the treatment. The use of cetuximab in combination with radiotherapy does not increase the side effects of radiotherapy. At the end of the follow-up, 17 patients died.Conclusion: Cetuximab, with its highly targeted mechanism of action and synergistic activity with current treatment modalities, is a valuable treatment option in head and neck patients. The effect of the epidermal growth factor receptor antagonist occurs without any change in the pattern and the severity of toxicity usually associated with head and neck radiation. Cetuximab seems

    Periodontal diseases including tooth loss might increase systemic inflammation, lead to immune dysregulation and alter gut microbiota, thereby possibly influencing colorectal carcinogenesis. Few epidemiological studies have examined the association between periodontal diseases and colorectal cancer (CRC) risk. We collected information on the periodontal disease (defined as history of periodontal bone loss) and number of natural teeth in the Nurses' Health Study. A total of 77,443 women were followed since 1992. We used Cox proportional hazard models to calculate multivariable hazard ratios (HRs) and 95% confidence intervals (95% CIs) after adjustment for smoking and other known risk factors for CRC. We documented 1,165 incident CRC through 2010. Compared to women with 25-32 teeth, the multivariable HR (95% CI) for CRC for women with periodontal disease, HRs for CRC were 0.91 (95% CI 0.74-1.12) for periodontal disease, and 1.22 (95% CI 0.91-1.63) when limited to moderate to severe periodontal disease. The results were not modified by smoking status, body mass index or alcohol consumption. Women with fewer teeth, possibly moderate or severe periodontal disease, might be at a modest increased risk of developing CRC, suggesting a potential role of oral health in colorectal carcinogenesis. © 2016 UICC.

    The high incidence and low mortality of breast cancer surgery has led to an increasing emphasis on the cosmetic outcome of surgical treatment. Advances in aesthetic evaluation, as well as surgical planning and outcome prediction, have been investigated by using geometrically precise 3D modelling of the breast surface prior to surgery and after the procedure. However, existing solutions are based on expensive site specific setups and remain weakly validated. In this paper, we explore the possibility of using low-cost RGBD cameras as an affordable and mobile system for breast surface reconstruction. The methodology relies on sensor calibration, uncertainty-driven point filtering, dense reconstruction and subsequent multi-view joint optimization to diffuse residual pose errors. Results from a phantom study, with ground truth obtained through commercially available scanners, indicate that the approach is promising with RMS errors in order of 2 mm. A clinical study shows the practical applicability of our method and compares favourably to high-end scanning solutions.

  3. Proteomic Study of HPV-Positive Head and Neck Cancers: Preliminary Results

    Full Text Available Human papillomavirus (HPV was recently recognized as a new risk factor for head and neck squamous cell carcinoma. For oropharyngeal cancers, an HPV+ status is associated with better prognosis in a subgroup of nonsmokers and nondrinkers. However, HPV infection is also involved in the biology of head and neck carcinoma (HNC in patients with a history of tobacco use and/or alcohol consumption. Thus, the involvement of HPV infection in HN carcinogenesis remains unclear, and further studies are needed to identify and analyze HPV-specific pathways that are involved in this process. Using a quantitative proteomics-based approach, we compared the protein expression profiles of two HPV+ HNC cell lines and one HPV− HNC cell line. We identified 155 proteins that are differentially expressed (P<0.01 in these three lines. Among the identified proteins, prostate stem cell antigen (PSCA was upregulated and eukaryotic elongation factor 1 alpha (EEF1α was downregulated in the HPV+ cell lines. Immunofluorescence and western blotting analyses confirmed these results. Moreover, PSCA and EEF1α were differentially expressed in two clinical series of 50 HPV+ and 50 HPV− oral cavity carcinomas. Thus, our study reveals for the first time that PSCA and EEF1α are associated with the HPV-status, suggesting that these proteins could be involved in HPV-associated carcinogenesis.

    Efficacy, survival rates and adverse effects of the combined therapy of irradiation with intravaginal bleomycin suppositories were analyzed and discussed in 49 patients with uterine cervical cancer. The results were as follows: 1. Histological examination of biopsy specimens from the uterine cervix taken just after the completion of this treatment showed favorable control over the primary lesions. However, the efficacy of the bleomycin suppositories was too mild to form a basis for treatment without intracavitary irradiation. Because of the low concentration of bleomycin in serum after suppository administration, it is thought that bleomycin would have little effect on distant metastases. 2. Survival rates in stage III patients were 83% at 12 months, 77% at 24 months and 70% at 36 months. These were superior to those for irradiation alone. 3. The major adverse effect of bleomycin suppositories was fever, reduction of the bleomycin dose in each suppository but controlled this to some extent Lung fibrosis or severe damage to the liver, kidney and bone marrow were not found.

    The Affordable Care Act (ACA) will expand health insurance options for cancer survivors in the USA. It is unclear how this legislation will affect their access to employer-sponsored health insurance (ESI). We describe the health insurance experiences for survivors of childhood cancer with and without ESI. We conducted a series of qualitative interviews with 32 adult survivors from the Childhood Cancer Survivor Study to assess their employment-related concerns and decisions regarding health insurance coverage. Interviews were performed from August to December 2009 and were recorded, transcribed, and content analyzed using NVivo 8. Uninsured survivors described ongoing employment limitations, such as being employed at part-time capacity, which affected their access to ESI coverage. These survivors acknowledged they could not afford insurance without employer support. Survivors on ESI had previously been denied health insurance due to their preexisting health conditions until they obtained coverage through an employer. Survivors feared losing their ESI coverage, which created a disincentive to making career transitions. Others reported worries about insurance rescission if their cancer history was discovered. Survivors on ESI reported financial barriers in their ability to pay for health care. Childhood cancer survivors face barriers to obtaining ESI. While ACA provisions may mitigate insurance barriers for cancer survivors, many will still face cost barriers to affording health care without employer support.

    Full Text Available OBJECTIVE: We have measured the concentration of immunoreactive neutrophil elastase (ir-NE in the tumor extracts of 313 primary human breast cancers. Sufficient time has elapsed, and we are now ready to analyze its prognostic value in human breast cancer. METHODS: ir-NE concentration in tumor extracts was determined with an enzyme-linked immunosorbent assay that enables a rapid measurement of both free-form ir-NE and the α1-protease inhibitor-complexed form of ir-NE. We analyzed the prognostic value of this enzyme in human breast cancer in univariate and multivariate analyses. RESULTS: Patients with breast cancer tissue containing a high concentration of ir-NE had poor survival compared to those with a low concentration of ir-NE at the cutoff point of 9.0 µg/100 mg protein (P = .0012, which had been previously determined in another group of 49 patients. Multivariate stepwise analysis selected lymph node status (P= .0004; relative risk = 1.46 and ir-NE concentration (P= .0013; relative risk = 1.43 as independent prognostic factors for recurrence. CONCLUSIONS: Tumor ir-NE concentration is an independent prognostic factor in patients with breast cancer who undergo curative surgery. This enzyme may play an active role in tumor progression that leads to metastasis in human breast cancer.

    Studies reporting the association between change in weight or body mass index during midlife and risk of colorectal cancer have found inconsistent results, and only one study to date has reported the association between change in waist circumference (a measure of central adiposity) and risk of colorectal cancer. We investigated the association between risk of colorectal cancer and changes in directly measured waist circumference and weight from baseline (1990-1994) to wave 2 (2003-2007). Cox regression, with age as the time metric and follow-up starting at wave 2, adjusted for covariates selected from a causal model, was used to estimate the Hazard Ratios (HRs) and 95 % Confidence Intervals (CIs) for the change in waist circumference and weight in relation to risk of colorectal cancer. A total of 373 cases of colorectal cancer were diagnosed during an average 9 years of follow-up of 20,605 participants. Increases in waist circumference and weight were not associated with the risk of colorectal cancer (HR per 5 cm increase in waist circumference = 1.02; 95 % CI: 0.95, 1.10; HR per 5 kg increase in weight = 0.93; 0.85, 1.02). For individuals with a waist circumference at baseline that was less than the sex-specific mean value there was a slight increased risk of colorectal cancer associated with a 5 cm increase in waist circumference at wave 2 (HR = 1.08; 0.97, 1.21). Increases in waist circumference and weight during midlife do not appear to be associated with the risk of colorectal cancer.

    Recent epidemiological data have contributed to the formulation of the hypothesis about the long-term safety of pioglitazone, a thiazolidinedione (TZD), with respect to malignancies, in particular bladder cancer. The primary aim of this meta-analysis of randomized clinical trials, not designed a priori to test this hypothesis, was to explore whether TZDs affect the risk of cancer. A meta-analysis was performed including published and unpublished randomized trials with a duration of at least 52 weeks, enrolling patients with or without diabetes, comparing TZDs with either placebo or other drug therapies on various different outcomes. We found 22 trials reporting at least one cancer and enrolling 13,197 patients to TZD (pioglitazone: n = 3,710 and rosiglitazone: n = 9,487) and 12,359 to placebo or active comparator groups. The mean follow-up was 26.1 months. Overall, those assigned at random to TZDs had a significant reduction (MH-OR 0.85 [0.73-0.98]; p = 0.027) in the incidence of malignancies, with no significant difference in effect between pioglitazone and rosiglitazone. Specifically, subgroup analyses showed a significant reduction for rosiglitazone (MH-OR 0.82 [0.69-0.98]; p = 0.029), but not for pioglitazone (MH-OR 0.66 [0.34-1.28]; p = 0.22). In further subgroup analyses of site-specific malignancies based on the data from four trials, the risk of bladder cancer with pioglitazone (MH-OR) was 2.05 [0.84-5.02]; p = 0.12. Further, rosiglitazone, but not pioglitazone, was associated with a significantly reduced risk of bowel cancer. In contrast, pioglitazone, but not rosiglitazone, was associated with a significant reduction in breast cancer. The present meta-analysis of trials, not designed a priori to test the hypothesis, provides reassuring evidence that TZDs are not associated with risk of overall malignancies. In fact, they are compatible with the possibility of a decreased risk of cancer. In site-specific subgroup analyses, for rosiglitazone, there was a

    Background: The type of instrument affects the amount of debris extruded. The aim of this study was to compare the effect of retreatment systems and supplementary file application on the amount of apical debris extrusion. Materials and Methods: Forty-eight extracted mandibular premolars with a single canal and similar length were selected. The root canals were prepared with the ProTaper Universal system with a torque-controlled engine. The root canals were dried and were obturated using Gutta-percha and sealer. The specimens were randomly divided into four equal groups according to the retreatment procedures (Group 1, Mtwo retreatment files; Group 2, Mtwo retreatment files + Mtwo rotary file #30 supplementary file; Group 3, ProTaper Universal retreatment (PTUR) files; and Group 4, PTUR files + ProTaper F3 supplementary file). The extruded debris during instrumentation were collected into preweighed Eppendorf tubes. The amount of apically extruded debris was calculated by subtracting the initial weight of the tube from the final weight. Three consecutive weights were obtained for each tube. Results: No statistically significant difference was found in the amount of apically extruded debris between Groups 1 and 3 (P = 0.590). A significant difference was observed between Groups 1 and 2 (P < 0.05), and between Groups 3 and 4 (P < 0.05). Conclusions: The use of supplementary file significantly increased the amount of apically extruded debris. PMID:27563185

    Purpose. A clinical feasibility study using a removable prostate stent as fiducial for image-guided radiotherapy (IGRT) of localized prostate cancer (PC). Material and methods. The study included patients with local or locally advanced PC. The clinical target volume (CTV) was outlined on magnetic resonance (MR) images co-registered to planning computer tomography (CT) images. Daily online IGRT was delivered using the stent as fiducial. Risk of migration was estimated using multiple MR. Acute urinary toxicity was scored using the international prostate symptom score (IPSS). Late gastro-intestinal (GI) and genito-urinary (GU) toxicity was scored using the Radio Therapy Oncology Group (RTOG) score, biochemical failure (BF) was defined as an elevation of prostate specific antigen (PSA) above nadir plus 2 ng/ml after radiotherapy. Results. One hundred men were enrolled in the study. Ninety completed radiotherapy with the stent as fiducial. No migration of the stent was seen, but three cases of dislocation of the stent to the bladder were observed. Acute urinary toxicity based on IPSS was comparable to toxicity in patients who had gold markers (GM) as fiducials. Removal of the stent was associated with a high frequency of urinary retention. Late GI and GU toxicity and BF were comparable to those of other studies, but longer observation time is needed. Conclusions. This study reports the first clinical results of using a prostate stent as fiducial. No migration of the stent observed. Dislocation of the stent to the urinary bladder was observed in three cases, requiring removal of the stent and insertion of a new fiducial. Acute toxicity during radiotherapy evaluated from IPSS was comparable to toxicity in patients with GM. Removal of the stent was associated with a high frequency of post procedural urinary retention. Late toxicity and BF were comparable to those of other studies, though longer observation time is needed

    Background: Paclitaxel (Taxol) has been shown to be effective in metastatic bladder cancer as single agent and in combination with other cytotoxic drugs. Its efficacy seems to be comparable to cisplatin. We have used paclitaxel as alternative to cisplatin in selected patients with simultaneous radiochemotherapy. The obiective of this articie is to summarize the preliminary results with regard to feasibility and toxicity. Patients and Methods: From 10/97 through 10/98 7 patients with locally advanced or recurrent urothelial bladder cancer were treated with radiotherapy and simultaneous paclitaxel {+-} cisplatin. All patients had macroscopic irresectable residual tumor after transurethral surgery or cystectomy. Paclitaxel was given twice weekly in a daily dosage of 25 through 35 mg/m{sup 2} as 1-hour-infusion. Cisplatin was given in a dosage of 25 mg/m{sup 2} daily on days 1 to 5. Results: All patients completed the scheduled therapy regimen. The acute toxicity consisted mainly of enteritis (Grade I to II CTC). As severe toxicity, 1 severe skin reaction in the groins (Grade III) after 20 Gy and 1 Grade-III enteritis were noted. Both patients with severe complications recovered within 4 weeks after treatment. Hematological toxicity was mild to moderate in all cases. Conclusions: This report suggests that paclitaxel is a promising agent for simultaneous radiochemotherapy protocols. The clinical value remains to be better defined especially the question whether paclitaxel may improve the results if used as alternative to standard cisplatin. At the moment paclitaxel offers at least an attractive alternative to cisplatin in patients with impaired renal function. (orig.) [German] Hintergrund: Paclitaxel (Taxol) hat sich bei metastasierenden Blasenkarzinomen allein und in Kombination mit anderen Zytostatika als effektiv erwiesen. Seine Wirksamkeit scheint der von Cisplatin vergleichbar zu sein. Wir haben Paclitaxel bei ausgewaehlten Patienten im Rahmen einer simultanen

    Full Text Available Abstract Background A large prospective study in patients with type 2 diabetes (T2D, the German D2C cohort, is presently being enumerated to investigate risk factors of incident cancer in diabetic patients. Study setting A disease management program was offered, on a voluntary basis, to all T2D patients who were members of a statutory health insurance fund in Germany. This first feasibility report uses data from 26.742 T2D patients, who were 40 to 79 years old, resided in the Muenster District, and who were enrolled between June 2003 and July 2008. Cancer cases were identified through the regional Cancer Registry. Methods Invasive cancer cases were identified using probabilistic record linkage procedures and pseudonymised personal identifiers. Censoring date was December 31, 2008. We included only first cancers, leaving 12.650 male and 14.092 female T2D with a total of 88.778 person-years (py. We computed standardised incidence ratios (SIR for external comparisons and we employed Cox regression models and hazard ratios (HR within the cohort. Results We identified 759 first cancers among male T2D patients (18.7 per 1,000 py and 605 among females (12.7 per 1,000 py. The risk of any incident cancer in T2D was raised (SIR = 1.14; 95% confidence interval [1.10 - 1.21], in particular for cancer of the liver (SIR = 1.94 [1.15 - 2.94] and pancreas (SIR = 1.45 [1.07-1.92]. SIRs decreased markedly with time after T2D diagnosis. In Cox models, adjusting for diabetes duration, body mass index and sex, insulin therapy was related to higher cancer risk (HR = 1.25 [1.17 - 1.33]. No effect was seen for metformin. Discussion Our study demonstrates feasibility of record linkage between DMP and cancer registries. These first cohort results confirm previous reports. It is envisaged to enhance this cohort by inclusion of further regions of the state, expansion of the follow-up times, and collection of a more detailed medication history.

    Expression profile of normal tissue is primary source to find genes showing aberrant expression pattern specific in matched cancer tissue, but sample number of normal control in public gene expression repositories is disproportionally small compared to cancer and scattered in several datasets. We built oncopression by integrating several datasets into one large dataset for comprehensive analysis about 25 types of human cancers including 20 640 cancer samples and 6801 normal control profiles. Expression profiles in cancers can be directly compared to normal tissue counterparts. Validity of the integration was tested using immunohistochemical staining results and principal component analysis. We have utilized the pre-release version of oncopression to identify cancer-specific genes in several studies. Free access at http://www.oncopression.com and all expression data are available for download at the site. cchoi@kaist.ac.kr or jungsullee@gmail.com. Supplementary data are available at Bioinformatics online.

    The supplementary motor area (SMA-proper) is important for the programming and execution of motor, speech, and other elaborative functions. SMA is frequently involved by brain tumors (particularly WHO grade II gliomas). Surgery in this area can be followed by the 'SMA syndrome', characterised by contralateral akinesia and mutism. We present a case of Falcine meningioma in the region of the right SMA which developed SMA syndrome. Our patient showed complete recovery of neurological function but the process was slow with a specific pattern.

    Mitigation of low-frequency electro-mechanical oscillations is essential for secure operation of power systems. The fast acting, power electronics based FACTS controllers which are capable of improving both steady state and dynamic performance permit newer approaches to system stabilization. The objective of the work presented in this paper is to carry out a coordinated design of supplementary modulation controllers (SMCs) for UPFC and to evaluate their performance. The effectiveness of the SMCs in damping the critical modes is tested on a four machine, 10 bus system. (Author)

    Full Text Available The aim of this research was to probed whether using supplementary readings (short stories containing idioms increase conceptual fluency of L2 learners. In line with the goal of the study, first, the researcher selected a sample of 30 female lower-intermediate L2 learners from Sadr Private Language Centre in Isfahan.  She selected them based on their scores (75 or higher in the previous term final exam. The researcher divided them into two groups. Then, she held a pre-test containing 30 multiple choice questions and registered their scores out of 30. Questions were mainly taken from the exercises of the book ‘Can You Believe It? (1’. Next, she taught idioms to both groups 15 minutes each session and for thirty sessions, but provided only the experimental group with supplementary readings taken from the mentioned book. After that, she held a post-test containing 30 multiple choice questions and again registered their scores. Questions were taken again from book exercises with a higher level of difficulty comparing to the pre-test. Finally, the researcher compared the results obtained from groups’ mean scores, frequency of obtained scores, and t-test on pre-test and post-test. The results of the study showed that the experimental group accomplished far better than the control group on the post-test. It also showed that the experimental group development in terms of conceptual fluency was meaningful and reliable. Therefore, it can be concluded that using supplementary readings has positive effect on developing conceptual fluency of L2 learners.

    Background Prostate cancer survivors with a rising prostate specific antigen (PSA) level have few treatment options, experience a heightened state of uncertainty about their disease trajectory that might include the possibility of cancer metastasis and death, and often experience elevated levels of distress as they have to deal with a disease they thought they had conquered. Guided by self-regulation theory, the present study examined the cognitive and affective processes involved in shared decision making between physician and patients who experience a rising PSA after definitive treatment for prostate cancer. Methods In-depth interviews were conducted with 34 prostate cancer survivors who had been diagnosed with a rising PSA (i.e., biochemical failure) within the past 12 months. Survivors were asked about their experiences and affective responses after being diagnosed with a rising PSA and while weighing potential treatment options. In addition, patients were asked about their decision-making process for the initial prostate cancer treatment. Results Compared to the initial diagnosis, survivors with a rising PSA reported increased negative affect following their diagnosis, concern about the treatability of their disease, increased planning and health behavior change, heightened levels of worry preceding doctor’s appointments (especially prior to the discussion of PSA testing results), and a strong reliance on physicians’ treatment recommendations. Conclusions Prostate cancer survivors’ decision-making processes for the treatment of a rising PSA are markedly different from those of the initial diagnosis of prostate cancer. Because patients experience heightened distress and rely more heavily on their physicians’ recommendations with a rising PSA, interactions with the health care provider provide an excellent opportunity to address and assist patients with managing the uncertainty and distress inherent with rising PSA levels.

    Colorectal cancer is an alcohol-related malignancy; however, the association appears to be stronger among Asian populations with a relatively high prevalence of the slow-metabolizing aldehyde dehydrogenase variant. To examine the association between alcohol consumption and colorectal cancer in Japanese, the authors analyzed original data from five cohort studies that measured alcohol intake using validated questionnaires at baseline. Hazard ratios were calculated in the individual studies, with adjustment for a common set of variables, and then combined using a random-effects model. During 2,231,010 person-years of follow-up (ranging variously from 1988 to 2004), 2,802 colorectal cancer cases were identified. In men, multivariate-adjusted pooled hazard ratios for alcohol intakes of 23-45.9 g/day, 46-68.9 g/day, 69-91.9 g/day, and > or =92 g/day, compared with nondrinking, were 1.42 (95% confidence interval (CI): 1.21, 1.66), 1.95 (95% CI: 1.53, 2.49), 2.15 (95% CI: 1.74, 2.64), and 2.96 (95% CI: 2.27, 3.86), respectively (p for trend colorectal cancer cases in men were attributable to an alcohol intake of > or =23 g/day. An alcohol-colorectal cancer association seems to be more apparent in Japanese than in Western populations. Whether this difference can be ascribed to genetic or environmental factors needs to be clarified.

    To compare mammography (MG), contrast-enhanced spectral mammography (CESM), and magnetic resonance imaging (MRI) in the detection and size estimation of histologically proven breast cancers using postoperative histology as the gold standard. After ethical approval, 80 women with newly diagnosed breast cancer underwent MG, CESM, and MRI examinations. CESM was reviewed by an independent experienced radiologist, and the maximum dimension of suspicious lesions was measured. For MG and MRI, routine clinical reports of breast specialists, with judgment based on the BI-RADS lexicon, were used. Results of each imaging technique were correlated to define the index cancer. Fifty-nine cases could be compared to postoperative histology for size estimation. Breast cancer was visible in 66/80 MG, 80/80 CESM, and 77/79 MRI examinations. Average lesion largest dimension was 27.31 mm (SD 22.18) in MG, 31.62 mm (SD 24.41) in CESM, and 27.72 mm (SD 21.51) in MRI versus 32.51 mm (SD 29.03) in postoperative histology. No significant difference was found between lesion size measurement on MRI and CESM compared with histopathology. Our initial results show a better sensitivity of CESM and MRI in breast cancer detection than MG and a good correlation with postoperative histology in size assessment. (orig.)

    AIM: To analyze the correlation between preexisting comorbidity and other clinicopathological features, short-term surgical outcome and long-term survival in elderly patients with colorectal cancer (CRC). METHODS: According to age, 403 patients operated on for CRC in our department were divided into group A (< 70 years old) and group B (≥ 70 years old) and analyzed statistically.RESULTS: Rectal localization prevailed in group A (31.6% vs 19.7%, P = 0.027), whereas the percentage of R0 resect ions was 77% in the two groups.Comorbidity rate was 46.2% and 69.1% for group A and B, respectively ( P < 0.001), with a huge difference as regards cardiovascular diseases. Overall, postoperative morbidity was 16.9% and 20.8% in group A and B,respectively ( P = 0.367), whereas mortality was limited to group B (4.5%, P = 0.001). In both groups, patients who suffered from postoperative complications had a higher overall comorbidity rate, with preexisting cardiovascular diseases prevailing in group B ( P = 0.003).Overall 5-year survival rate was significantly better for group A (75.2% vs 55%, P = 0.006), whereas no significant difference was observed considering diseasespecific survival (76.3% vs 76.9%, P = 0.674).CONCLUSION: In spite of an increase in postoperative mortality and a lower overall long-term survival for patients aged ≥ 70 years old, it should be considered that, even in the elderly group, a significant number of patients is alive 5 years after CRC resection.

    To analyse whether the self-evaluation of a clinical pathway improves the results of rectal cancer (RC) treatment. Patients operated on for RC were divided into 3 groups according to biannual modifications of a clinical pathway analysing several indicators. 166 patients: Group A: 2002-3 n=50, B: 2004-5 n=53 and C: 2006-7 n=63, without any differences in age, gender or comorbidity. Preoperative study improved with the introduction of CT scan: 76% in Group C vs. 6% in Group A (P<0.001). All Group C tumours were staged using MR, rectal ultrasound or both, compared to 84% in Group A (P<0.001). The rate of abdominal-perineal resections was reduced from 42% (Group A) to 17% (Group C); (P=0.007) and about 48% of surgeons in Group A vs. 94% in the C had a specific activity in coloproctology (P<0.001). The average lymph node count was: Group A=6.2+/-4.5 vs. 13+/-6.5 in the C and circumferential margin analysis was reported in 24% of Group A vs. 76% in Group C (P<0.001). Parameters such as perioperative blood transfusion, ICU admission, use of nasogastric tube, early feeding or epidural analgesia also improved progressively. Operative mortality decreased non-significantly to 4.7% and anastomotic leaks from 24% to 9.5% with a reduction in postoperative stay from 15 to 11 days during the period analysed (P=0.029). Several indicators have significantly improved in a relatively short period of time due to self-evaluations of the process.

    The role of diet in colorectal cancer (CRC) in Jordan has not been studied previously. This study aimed at examining the association between food groups (including grains, fruits, vegetables, milk, and meat and legumes) and CRC risk in Jordan. We compared intakes of the different food groups among CRC patients (n=167) and matched controls (n=240) by age, sex, occupation, and marital status. A validated food frequency questionnaire was used to collect dietary data. Logistic regression was used to evaluate the association of quartiles of intakes of the different food groups with CRC risk. In addition, the association of selected food items with CRC risk was examined. Odds ratios (ORs) for the fourth versus the first quartile of intake were 2.92 [95% confidence interval (CI): 1.40-6.08] for grains, 1.66 (95% CI: 0.81-3.40) for vegetables, 0.55 (95% CI: 0.26-1.16) for fruits, 0.96 (95% CI: 0.46-1.97) for milk, and 1.43 (95% CI: 0.68-2.98) for meat and legumes. In a comparison of the highest with the lowest weekly frequency of consumption, there was a direct association between the risk of CRC and the frequency of consumption of chicken (OR=2.52, 95% CI: 1.33-4.77). An increase in risk was observed with increased consumption of white bread (OR=3.13, 95% CI: 1.18-9.25), whereas consumption of whole bread was associated with a decreased risk for CRC (OR=0.32, 95% CI: 0.12-0.84). Our results support a role of diet in CRC. Direct associations were found for grains, white bread, and chicken, whereas an inverse relation was reported for whole bread.

    The early and late results of bypass surgery in 124 patients with unresectable oesophageal cancer are reported. Patients were grouped according to the extent of disease: group A, tumour localized to the oesophagus where severe pulmonary disease contra-indicated oesophagectomy (n = 9); group B, tumour less than or equal to 10 cm in length with mediastinal invasion (n = 81); group C, tumour greater than 10 cm in length with mediastinal invasion and/or fixed malignant lymph nodes (n = 33). Extent of disease was not recorded in one patient. The operative mortality was 4 per cent but 9 other patients died in hospital (hospital mortality, 11 per cent). Mortality was increased in patients undergoing colon bypass and in those with a large tumour load but these differences failed to reach statistical significance. The most frequent complication was neck sepsis, secondary to leakage from the proximal end of the excluded oesophagus. Eighty-nine per cent of the survivors could eat a normal, unrestricted diet on discharge and eighty-two per cent of survivors had complete and lasting relief from dysphagia. Median survival after bypass was 5 months but survival was significantly improved by radiotherapy to the tumour (P less than 0.001). Gastric bypass with radiotherapy is indicated in patients with extra-oesophageal spread of malignancy and in patients with tumours localized to the oesophagus who are unfit for resection. Bypass surgery may be contra-indicated in patients with a primary tumour greater than 10 cm in length and/or fixed lymph node metastases because mortality is increased and survival after operation is short.

    To analyze the results of locoregional and systemic therapy in the breast cancer patients with locoregional recurrence (LRR) after mastectomy. Seventy-one patients who received radiotherapy for isolated LRR after mastectomy between January 1999 and December 2009 were retrospectively reviewed. Among the 71 patients, 59 (83.1%) underwent wide excision and radiotherapy and 12 (16.9%) received radiotherapy alone. Adjuvant hormonal therapy was given to 45 patients (63.4%). Oncologic outcomes including locoregional recurrence-free survival, disease-free survival (DFS), and overall survival (OS) and prognostic factors were analyzed. Median follow-up time was 49.2 months. Of the 71 patients, 5 (7%) experienced second isolated LRR, and 40 (56%) underwent distant metastasis (DM). The median DFS was 35.6 months, and the 3- and 5-year DFS were 49.1% and 28.6%, respectively. The median OS was 86.7 months, and the 5-year OS was 62.3%. Patients who received hormone therapy together showed better 5-year DFS and OS than the patients treated with locoregional therapy only (31.6% vs. 22.1%, p = 0.036; 66.5% vs. 55.2%, p = 0.022). In multivariate analysis, higher N stage at recurrence was a significant prognostic factor for DFS and OS. Disease free interval (≤ 30 months vs. >30 months) from mastectomy to LRR was also significant for OS. The patients who received hormone therapy showed superior DFS and showed trend to better OS. DM was a major pattern of failure after the treatment of LRR after mastectomy. The role of systemic treatment for LRR after mastectomy should be investigated at prospective trials.

    The immediate goal of the trial was to determine the breast cancer patient tolerance and the toxicity of Laser immunotherapy (LIT), the optimal dose for the alteration of the course of the disease, and the reduction of the tumor burden. Ten stage III and IV cancer patients were treated, all of which were considered to be out of all other options. No toxicity or significant adverse reactions were observed and the treatment was well tolerated by all patients. Almost all the treated patients have had positive responses: A majority of patients experienced large-scale reduction of primary breast tumors, and all the stage IV patients experienced either complete or significant reductions in distant metastases in the lungs, liver, bone, and the brain, indicating a strong systemic effect of the treatment. We also report two cases of triple negative breast cancer patients that showed limited or no response to LIT.

    Internet-based online patient-nurse communication (OPNC) services can constitute an important opportunity to support patients to manage their illness between treatment and rehabilitation while being at home. We explored the content of messages sent by prostate and breast cancer patients to an OPNC service to identify symptoms, problems, concerns and information needs expressed in these messages. Using qualitative content analyses we examined 276 messages sent from 38 breast and 22 prostate cancer patients during 15 months. Two main themes emerged: Concerns about physical symptoms and treatment side effects; and worries and questions about treatment and follow up. Analyses showed that cancer patients have many serious unanswered questions and concerns that can create considerable uncertainty and anxiety. An OPNC service can to a great extent meet patients' need for advice and information and thus be an important health care supplement that can improve quality of care.

    Preoperative radiotherapy (pRT) for rectal cancer may reduce local recurrence and improve survival. This study was undertaken to assess a selective policy of pRT in rectal cancer. The aim was to determine whether patients likely to have involved circumferential margins (CRM) could be reliably selected for pRT using clinical criteria. We have used CRM and delay in surgery as outcome measures. Seventy-nine patients with rectal cancer were assessed for preoperative radiotherapy using clinical criteria. Twelve of 26 (46%) pRT patients had positive CRM compared with three of 53 (5.6%) who did not receive pRT (P benefit from radiotherapy and has avoided excessive delays prior to surgery. However, almost half of the pRT patients did not have involved CRM. With improved imaging techniques we may be able to refine our selection criteria further.

    Triple-negative breast cancer (TNBC) is associated with a poor prognosis. Surgery, radiotherapy, chemotherapy, and referral for genetic counseling are the standard of care. We assessed TNBC prevalence, management, and outcome using data from the population-based Geneva cancer registry. 2591 women had a first invasive stage I-III breast cancer diagnosed between 2003 and 2011. We compared TNBC to other breast cancers (OBC) by χ(2) -test and logistic regression. Kaplan-Meier survival curves, up to 31-12-2014, were compared using log-rank test. TNBC risk of mortality overall (OS) and for breast cancer (BCSS) was evaluated through Cox models. Linkage with the Oncogenetics and Cancer Prevention Unit (OCPU) database of the Geneva University Hospitals provided genetic counseling information. TNBC patients (n = 192, 7.4%) were younger, more often born in Africa or Central-South America than OBC, had larger and more advanced tumors. 18% of TNBC patients did not receive chemotherapy. Thirty-one (17%) TNBC women consulted the OCPU, 39% among those aged <40 years. Ten-year survival was lower in TNBC than OBC (72% vs. 82% for BCSS; P < 0.001; 80% vs. 91% for OS; P < 0.001). The mortality risks remained significant after adjustment for other prognostic variables. The strongest determinants of mortality were age, place of birth, and lymph node status. A substantial proportion of TNBC patients in Geneva did not receive optimal care. Over 60% of eligible women did not receive genetic counseling and 18% did not receive chemotherapy. To improve TNBC prognosis, comprehensive care as recommended by standard guidelines should be offered to all patients.

    Breast cancer is the most frequent malignant neoplasia worldwide. In emergent countries as Mexico, an increase has been shown in frequency and mortality, unfortunately, most cases in advanced loco-regional stages developed in young women. The success of breast screening in mortality reduction has been observed since 1995 in Western Europe and the United States, where as many as 40% mortality reduction has been achieved. Most countries guidelines recommends an annual or biannual mammography for all women >40 years of age. In 2005, FUCAM, a nonlucrative civil foundation in Mexico join with Mexico City government, initiated the first voluntary mammography screening program for women >40 years of age residing in Mexico City's Federal District. Mammographies were carried out with analogical mammographs in specially designed mobile units and were performed in the area of women's domiciles. This report includes data from the first 96,828 mammographies performed between March 2005 and December 2006. There were 1% of mammographies in Breast Imaging Reporting and Data System 0, 4, or 5 and 208 out of 949 women with abnormal mammographies (27.7%) had breast cancer, a rate of 2.1 per thousand, most of them in situ or stage I (29.4%) or stage II (42.2%) nevertheless 21% of those women with abnormal mammography did not present for further clinical and radiologic evaluation despite being personally notified at their home addresses. The breast cancer rate of Mexican women submitted to screening mammography is lower than in European or North American women. Family history of breast cancer, nulliparity, absence of breast feeding, and increasing age are factors that increase the risk of breast cancer. Most cancers were diagnosed in women's age below 60 years (68.5%) with a mean age of 53.55 corroborating previous data published. It is mandatory to sensitize and educate our population with regard to accepting to visit the Specialized Breast Centers.

    Full Text Available Abstract Background Gail and others developed a model (GAIL using age-at-menarche, age-at-birth of first live child, number of previous benign breast biopsy examinations, and number of first-degree-relatives with breast cancer as well as baseline age-specific breast cancer risks for predicting the 5-year risk of invasive breast cancer for Caucasian women. However, the validity of the model for projecting risk in South-East Asian women is uncertain. We evaluated GAIL and attempted to improve its performance for Singapore women of Chinese, Malay and Indian origins. Methods Data from the Singapore Breast Screening Programme (SBSP are used. Motivated by lower breast cancer incidence in many Asian countries, we utilised race-specific invasive breast cancer and other cause mortality rates for Singapore women to produce GAIL-SBSP. By using risk factor information from a nested case-control study within SBSP, alternative models incorporating fewer then additional risk factors were determined. Their accuracy was assessed by comparing the expected cases (E with the observed (O by the ratio (E/O and 95% confidence interval (CI and the respective concordance statistics estimated. Results From 28,883 women, GAIL-SBSP predicted 241.83 cases during the 5-year follow-up while 241 were reported (E/O=1.00, CI=0.88 to 1.14. Except for women who had two or more first-degree-relatives with breast cancer, satisfactory prediction was present in almost all risk categories. This agreement was reflected in Chinese and Malay, but not in Indian women. We also found that a simplified model (S-GAIL-SBSP including only age-at-menarche, age-at-birth of first live child and number of first-degree-relatives performed similarly with associated concordance statistics of 0.5997. Taking account of body mass index and parity did not improve the calibration of S-GAIL-SBSP. Conclusions GAIL can be refined by using national race-specific invasive breast cancer rates and mortality rates

    There is currently no consensus regarding first-line chemotherapy for patients with advanced gastric cancer (AGC) who are ineligible to receive trastuzumab. The objective of this study was to evaluate the efficacy and tolerance of triplets versus doublets by analyzing a national gastric cancer registry. Patients with AGC treated with polychemotherapy without associating trastuzumab were included from 2008 through 2016. The effect of triplets versus doublets was compared using 3 methods: Cox proportional hazards regression, propensity score matching (PSM), and coarsened exact matching (CEM). A total of 970 patients were recruited (doublets: n=569; triplets: n=401). In the multivariate Cox model, the use of triplets was associated with better overall survival (OS), with a hazard ratio (HR) of 0.84 (95% CI, 0.72-0.98; P=.035). After PSM, the sample contained 340 pairs. A significant increase in OS, 11.14 months (95% CI, 9.60-12.68) versus 9.60 months (95% CI, 8.44-10.75), was seen in favor of triplets (HR, 0.77; 95% CI, 0.65-0.92; stratified log-rank test, P=.004). The effect appeared to be comparable for anthracycline-based (HR, 0.78; 95% CI, 0.64-0.94) or docetaxel-based triplets (HR, 0.78; 95% CI, 0.60-1.009). The trend was similar after applying the CEM algorithm, with an HR of 0.78 (95% CI, 0.63-0.97; P=.03). Triplet therapy was viable and relative dose intensities exceeded 85%, except for cisplatin in DCX (docetaxel, cisplatin, capecitabine). Triplets had more severe toxicity overall, especially hematologic, hepatic, and mucosal adverse events. With the limitations of a retrospective study that examines a heterogeneous set of chemotherapy regimens, we found that triplets are feasible in daily practice and are associated with a discreet benefit in efficacy at the expense of a moderate increase in toxicity.

    2011-04-04

    Colorectal cancer is common in the Western world and is a leading cause of cancer related mortality. The introduction of multidisciplinary teams and focus on quality control has led to improved outcomes in which pathologists play a central role through feedback to surgeons, radiologists, and oncologists. This review focuses on the importance of pathological examination of the resection specimen and subsequent feedback to the surgical team regarding quality. Specific markers of oncological quality including grading the plane of surgery, tissue morphometry and lymph node yields are discussed.

    The association of colorectal cancer and abdominal aortic aneurysm (AAA) is infrequent but poses special problems of priority of treatment under elective circumstances. The purpose of this study was to retrospectively evaluate the outcome of 16 consecutive patients undergoing endovascular aneurysm repair (EVAR) followed by colectomy. Operative mortality was nil. Operative morbidity included two transient rise of serum creatinine level and one extraperitoneal anastomotic leakage which evolved favourably with conservative treatment. EVAR allowed a very short delay of treatment of colorectal cancer after aneurysm repair, minimizing operative complications.

    Triple-negative breast cancer (TNBC) is a heterogeneous disease in which tumors are defined by lack of expression of the estrogen receptor (ER), the progesterone receptor (PR), and the human epidermal growth factor receptor 2 (HER2) receptor. No targeted therapies are available for the treatment of TNBC, and chemotherapy remains the standard of care. Gene expression profiling has identified six distinct molecular subtypes of TNBC. The identification of novel targets, coupled with the development of therapies for different subsets of TNBC, holds great promise for the future treatment of this aggressive form of breast cancer. This review focuses on novel therapies in development for the treatment of TNBC.

    What's known on the subject? and What does the study add? Very few comparative studies to date evaluate the results of treatment options for prostate cancer using the most sensitive measurement tools. PSA has been identified as the most sensitive tool for measuring treatment effectiveness. To date, comprehensive unbiased reviews of all the current literature are limited for prostate cancer. This is the first large scale comprehensive review of the literature comparing risk stratified patients by treatment option and with long-term follow-up. The results of the studies are weighted, respecting the impact of larger studies on overall results. The study identified a lack of uniformity in reporting results amongst institutions and centres. A large number of studies have been conducted on the primary therapy of prostate cancer but very few randomized controlled trials have been conducted. The comparison of outcomes from individual studies involving surgery (radical prostatectomy or robotic radical prostatectomy), external beam radiation (EBRT) (conformal, intensity modulated radiotherapy, protons), brachytherapy, cryotherapy or high intensity focused ultrasound remains problematic due to the non-uniformity of reporting results and the use of varied disease outcome endpoints. Technical advances in these treatments have also made long-term comparisons difficult. The Prostate Cancer Results Study Group was formed to evaluate the comparative effectiveness of prostate cancer treatments. This international group conducted a comprehensive literature review to identify all studies involving treatment of localized prostate cancer published during 2000-2010. Over 18,000 papers were identified and a further selection was made based on the following key criteria: minimum/median follow-up of 5 years; stratification into low-, intermediate- and high-risk groups; clinical and pathological staging; accepted standard definitions for prostate-specific antigen failure; minimum patient

    The purpose of this study is to evaluate anal sphincter preservation rates, survival rates, and prognostic factors in patients with rectal cancer treated with preoperative chemoradiotherapy. Materials and Methods: One hundred fifty patients with pathologic confirmed rectal cancer and treated by preoperative chemoradiotherapy between January 1999 and June 2007. Of the 150 patients, the 82 who completed the scheduled chemoradiotherapy, received definitive surgery at our hospital, and did not have distant metastasis upon initial diagnosis were enrolled in this study. The radiation dose delivered to the whole pelvis ranged from 41.4 to 46.0 Gy (median 44.0 Gy) using daily fractions of 1.8-2.0 Gy at 5 days per week and a boost dose to the primary tumor and high risk area up to a total of 43.2-54 Gy (median 50.4 Gy). Sixty patients (80.5%) received 5-fluorouracil, leucovorin, and cisplatin, while 16 patients (19.5%) were administered 5-fluorouracil and leucovorin every 4 weeks concurrently during radiotherapy. Surgery was performed for 3 to 45 weeks (median 7 weeks) after completion of chemoradiotherapy. Results: The sphincter preservation rates for all patients were 73.2% (60/82). Of the 48 patients whose tumor was located at less than 5 cm away from the anal verge, 31 (64.6%) underwent sphincter-saving surgery. Moreover, of the 34 patients whose tumor was located at greater than or equal to 5 cm away from the anal verge, 29 (85.3%) were able to preserve their anal sphincter. A pathologic complete response was achieved in 14.6% (12/82) of all patients. The downstaging rates were 42.7% (35/82) for the T stage, 75.5% (37/49) for the N stage, and 67.1% (55/82) for the overall stages. The median follow-up period was 38 months (range 11 -107 months). The overall 5-year survival, disease-free survival, and locoregional control rates were 67.4%, 58.9% and 84.4%, respectively. The 5-year overall survival rates based on the pathologic stage were 100% for stage 0 (n=12), 59

    Sleep-related complaints are common among breast cancer survivors. However, the risk factors underlying sleep disturbances in this population are not completely understood. Some studies have shown that maintaining normal weight can result in a reduced risk of cancer-related symptoms, including sleep problems; however, data from published studies are not consistent. This study examined the associations between body mass index (BMI) and sleep-related complaints in breast cancer survivors. Self-reported survey data from 861 breast cancer survivors at a single institution were analyzed. BMI was calculated based on self-reported weight and height at the time of the survey. Daytime sleepiness was assessed using the Epworth Sleepiness Scale. Average sleep duration was calculated based on the reported hours of sleep on a typical weekday and weekend. Associations between BMI and the sleep outcomes were estimated using multivariable logistic regression. In adjusted models, BMI was not significantly associated with either excessive daytime sleepiness or "short" sleep pattern (≤ 6 h) in our sample of breast cancer survivors. Younger age, presence of strong acute pain, and lower level of education were independent risk factors for excessive daytime sleepiness. African American race, presence of strong acute pain, and lower level of education were independent risk factors for being a short sleeper. Findings from this study indicate that BMI is not independently associated with sleep-related outcomes among breast cancer survivors. More research is needed to identify cancer survivors who are at increased risk for sleep disturbances as well as the mechanisms that underlie such disturbances.

    To assess the diagnostic value of integrated PET/MRI for whole-body staging of cervical cancer patients, as well as to investigate a potential association between PET/MRI derived functional parameters and prognostic factors of cervical cancer. The present study was approved by the local institutional review board. Twenty-seven patients with histopathologically confirmed cervical cancer were prospectively enrolled in our study. All patients underwent a whole-body PET/MRI examination after written informed consent was obtained. Two radiologists separately evaluated the PET/MRI data sets regarding the determination of local tumor extent of primary cervical cancer lesions, as well as detection of nodal and distant metastases. Furthermore, SUV and ADC values of primary tumor lesions were analyzed and correlated with dedicated prognostic factors of cervical cancer. Results based on histopathology and cross-sectional imaging follow-up served as the reference standard. PET/MRI enabled the detection of all 27 primary tumor lesions of the uterine cervix and allowed for the correct determination of the T-stage in 23 (85 %) out of the 27 patients. Furthermore, the calculated sensitivity, specificity and diagnostic accuracy for the detection of nodal positive patients (n = 11) were 91 %, 94 % and 93 %, respectively. PET/MRI correctly identified regional metastatic disease (N1-stage) in 8/10 (80 %) patients and non-regional lymph node metastases in 5/5 (100 %) patients. In addition, quantitative analysis of PET and MRI derived functional parameters (SUV; ADC values) revealed a significant correlation with pathological grade and tumor size (p < 0.05). The present study demonstrates the high potential of integrated PET/MRI for the assessment of primary tumor and the detection of lymph node metastases in patients with cervical cancer. Providing additional prognostic information, PET/MRI may serve as a valuable diagnostic tool for cervical cancer patients in a pretreatment setting

    Therapeutic strategy for prostate cancer is decided according to T stage, Gleason score, and prostate-specific antigen (PSA) level. These clinical factors are not accurate enough to predict individual risk of local failure of prostate cancer after radiotherapy. Parameters involved with radiosensitivity are required to improve the predictive capability for local relapse. We analyzed 58 patients with localized adenocarcinoma of the prostate between August 2007 and October 2010 treated with 76 Gy of intensity-modulated radiotherapy (IMRT) as a discovery cohort and 42 patients between March 2001 and May 2007 treated with three-dimensional conformal radiotherapy (3D-CRT) as a validation cohort. Immunohistochemical examination for proteins involved in nonhomologous end-joining was performed using biopsy specimens. Ku70 expression was not correlated with various clinical parameters, such as the Gleason score and D'amico risk classification, indicating that Ku70 expression was an independent prognostic factor. The predictive value for PSA relapse was markedly improved after the combination of Gleason score and Ku70 expression, as compared with Gleason score alone. In patients treated with radiotherapy and androgen deprivation therapy (ADT), no relapses were observed in patients with Gleason score ≤7 or low Ku70 expression. In contrast, patients with Gleason score ≥8 and high Ku70 expression had high PSA relapse rates. In the validation cohort, similar results were obtained. Treatment with 76 Gy and ADT can be effective for patients with Gleason score ≤7 or low Ku70 expression, but is not enough for patients with Gleason score ≥8 and high Ku70 expression and, thus, require other treatment approaches.

    The fecal immunochemical test (FIT) is commonly used for colorectal cancer screening and positive test results require follow-up colonoscopy. However, follow-up intervals vary, which may result in neoplastic progression. To evaluate time to colonoscopy after a positive FIT result and its association with risk of colorectal cancer and advanced-stage disease at diagnosis. Retrospective cohort study (January 1, 2010-December 31, 2014) within Kaiser Permanente Northern and Southern California. Participants were 70 124 patients aged 50 through 70 years eligible for colorectal cancer screening with a positive FIT result who had a follow-up colonoscopy. Time (days) to colonoscopy after a positive FIT result. Risk of any colorectal cancer and advanced-stage disease (defined as stage III and IV cancer). Odds ratios (ORs) and 95% CIs were adjusted for patient demographics and baseline risk factors. Of the 70 124 patients with positive FIT results (median age, 61 years [IQR, 55-67 years]; men, 52.7%), there were 2191 cases of any colorectal cancer and 601 cases of advanced-stage disease diagnosed. Compared with colonoscopy follow-up within 8 to 30 days (n = 27 176), there were no significant differences between follow-up at 2 months (n = 24 644), 3 months (n = 8666), 4 to 6 months (n = 5251), or 7 to 9 months (n = 1335) for risk of any colorectal cancer (cases per 1000 patients: 8-30 days, 30; 2 months, 28; 3 months, 31; 4-6 months, 31; and 7-9 months, 43) or advanced-stage disease (cases per 1000 patients: 8-30 days, 8; 2 months, 7; 3 months, 7; 4-6 months, 9; and 7-9 months, 13). Risks were significantly higher for examinations at 10 to 12 months (n = 748) for any colorectal cancer (OR, 1.48 [95% CI, 1.05-2.08]; 49 cases per 1000 patients) and advanced-stage disease (OR, 1.97 [95% CI, 1.14-3.42]; 19 cases per 1000 patients) and more than 12 months (n = 747) for any colorectal cancer (OR, 2.25 [95% CI, 1.89-2.68]; 76 cases per 1000

    Mammographic screening programmes are now established in developing countries. We present an analysis of the first screening programme in sub-Saharan Africa. Women aged > or = 40 years were identified at three primary healthcare centres in the Western Cape Province, South Africa, and after giving informed consent underwent mammography at a mobile unit. After a single reading, patients with American College of Radiology Breast Imaging Reporting and Data System (BIRADS) 3 - 5 lesions were referred to a tertiary centre for further management. Between 1 February 2011 and 31 August 2012, 2 712 screening mammograms were performed. A total of 261 screening mammograms were reported as BIRADS 3 - 5 (recall rate 9.6%). Upon review of the 250 available screening mammograms, 58 (23%) were rated benign or no abnormalities (BIRADS 1 and 2) and no further action was taken. In 32 women, tissue was acquired (biopsy rate for the series 1.2%); 10 cancers were diagnosed (biopsy malignancy rate 31%). For the entire series of 2 712 screening mammograms, the cancer diagnosis rate was 3.7/1 000 examinations. Of 10 cancers diagnosed at screening, 5 were TNM clinical stage 0, 2 stage I and 3 stage II. The low cancer detection rate achieved, and the technical and multiple administrative problems experienced do not justify installation of a screening programme using the model utilised in this series.

    Full Text Available A case – control study of 257 women with breast cancer and 565 control women was conducted to investigate the effect of life-time sport activity on breast cancer risk. Information was collected by questionnaire about sports played, frequency of participation and duration. The activity levels were determined using frequency variable weighted for metabolic equivalents of energy expenditure (MET. Multivariate logistic regression analyses were used to compute odds ratios (ORs and 95% confidence intervals (CIs. A full assessment of confounding and effect modification was undertaken. The odds ratios for increasing tertiles of sport activity were 1.00 (referent, 0.50 (CI: 0.33-0.76 and 0.44 (CI: 0.28-0.64, respectively (P-trend = 0.000. Comparing sport active women to inactive women the OR was 0.49 (CI: 0.35-0.69. Models stratified according to body mass index, age at menarche, age at first full term pregnancy, intake of vegetables and fruits, and experience of stress were examined. In models stratified the risks of breast cancer were also reduced with higher levels of activity in sport. The conclusion is that women who participated in sports have a reduced risk of breast cancer.

    Patients turn to National Cancer Institute (NCI) -designated comprehensive cancer centers because of perceived better quality and more timely access to care. However, recent studies have found that patients at various institutions may struggle to gain access to an appointment or obtain consistent information from attendants. Our study employs a mystery shopper format to identify and quantify barriers faced by patients seeking to make a first consultation appointment across a homogenous sample of 40 NCI-designated comprehensive cancer centers. Five mystery shoppers used a standardized call script to inquire about first available appointment times and service offerings. When inquiring about a date for a first available appointment, 29% of callers were unable to secure an estimated date without registering into the center's database, 51% were able to secure an estimated date, and 20% were provided with an actual date. Of estimated or actual dates for a first available appointment, 74% were greater than 1 week away. There was no statistically significant variation between appointment availability across insurance type or US region. Our study highlights the difficulty of accessing information about appointment availability. Although not statistically significant, inquiries regarding first available appointments for Medicaid patients resulted in longer estimated or actual wait times than those for patients with private insurance, and Medicaid shoppers noted qualitative differences. Although our study was limited by small sample size and imperfect analytic methods, our results suggest the need for more efficient and accessible care for patients at our nation's top cancer centers.

    v-ets erythroblastosis virus E26 oncogene homolog 1 (ETS-1) plays crucial roles in a spectrum of malignancies. ETS-1 has gained attention in cancer research for its importance in cell migration, invasion and proliferation. In the present study, we focused on the effect of ETS-1 on epithelial-mesenchymal transition (EMT), which is characterized by reduced E-cadherin expression and increased N-cadherin expression. We found that ETS-1 mRNA expression was positively correlated with N-cadherin and negatively correlated with E-cadherin mRNA expression in five pancreatic cancer cell lines. To elucidate the functionality of ETS-1 on EMT in pancreatic cancer cells, we constructed a green fluorescent protein (GFP)-expressing plasmid carrying ETS-1 short hairpin RNA (shRNA), and transfected Panc-1 cells with the plasmid. We detected reduced N-cadherin and vascular endothelial growth factor yet higher E-cadherin expression in the ETS-1-silenced cells compared with the control group. In addition, we observed reduced cell migration and increased adhesion in these cells. Our data showed that ETS-1 actively functioned as a regulator of EMT in Panc-1 cells, and provide additional evidence supporting a fundamental role for ETS-1 in metastatic pancreatic cancer cells. These results suggest that analysis of ETS-1 expression levels may provide an avenue for evaluating prognosis in pancreatic cancer.

    As a result of the need to produce more durable structures, chemical additives to concrete such as superplasticizers and supplementary cementing materials such as silica fume and fly ash, attract considerable interest. The combined use of these materials produces a synergistic effect which results in a range of modifications such as improved mobility, cohesiveness, ultimate strength and durability, making it possible to place highly durable concrete under a variety of conditions. This paper examines the role of additives in augmenting desirable features in fly ash or silica fume/portland cement mixes, using specific examples to illustrate the manner in which these admixtures compensate for limitations and increase the effectiveness of both of these supplementary cementing materials. Rheological, structural and durability characteristics are the focus of interest. Results show that admixtures influence both the hydration and packing efficiency in the fly ash or silica fume concrete, producing significant improvements in the concrete that could not be readily attained if the materials were used individually. 30 refs., 3 tabs., 9 figs.

    Relating supplementary cultivated land (SCL) quantity and quality with the occupied cultivated land (OCL) grade as well as realizing conversion between them are crucial to keep the balance between SCL and OCL, to protect the limited farming resources, to guarantee the security of national food, to harmonize the relationship between human and land resources, and to promote sustainable economic development. The Jianhan plain, one of China's grain production bases, was chosen for a case study to quantify the relationships between the grade index of farmland utilization and standard food output based on the resulting grade of agricultural land. Linear regression is used to model the relationships for 2778 samples from the grade of agricultural land obtained by field mapping. The average of grade index for different utilization grades was estimated by the area weighted average method. The results demonstrate that quantity-quality grade conversion coefficient of supplementary cultivated land, and the method used in this study are powerful tools to quantify the relationship between the quantity and quality of the SCL and the grade and realize conversion of OCL. Theses results can be used for protecting the quantity and quality of cultivated land and optimizing design for land consolidation project as well as determining the reasonable scale and layout of land use planning in the Jianghan plain.

    The purpose of this study was to describe treatment patterns of radiotherapy (RT) for prostate cancer in Korea. A questionnaire about radiation treatment technique and principles in 2013 was sent to 83 radiation oncologists and data from 57 hospitals were collected analyzed to find patterns of RT for prostate cancer patients in Korea. The number of patients with prostate cancer treated with definitive RT ranged from 1 to 72 per hospital in 2013. RT doses and target volumes increased according to risk groups but the range of radiation doses was wide (60 to 81.4 Gy) and the fraction size was diverse (1.8 to 5 Gy). Intensity-modulated radiation therapy was used for definitive treatment in 93.8% of hospitals. Hormonal therapy was integrated with radiation for intermediate (63.2%) and high risk patients (77.2%). Adjuvant RT after radical prostatectomy was performed in 46 hospitals (80.7%). Indications of adjuvant RT included positive resection margin, seminal vesicle invasion, and capsular invasion. The total dose for adjuvant RT ranged from 50 to 72 Gy in 24–39 fractions. Salvage RT was delivered with findings of consecutive elevations in prostate-specific antigen (PSA), PSA level over 0.2 ng/mL, or clinical recurrence. The total radiation doses ranged from 50 to 80 Gy with a range of 1.8 to 2.5 Gy per fraction for salvage RT. This nationwide patterns of care study suggests that variable radiation techniques and a diverse range of dose fractionation schemes are applied for prostate cancer treatment in Korea. Standard guidelines for RT in prostate cancer need to be developed.

    The association between cancer and immune-mediated rheumatic conditions is controversial, especially as far as polymyalgia rheumatica (PMR) is concerned. Furthermore, no clinical feature has been shown to be suggestive of a paraneoplastic rheumatic syndrome. With the present study, we aim to address both these issues. The study population comprised N = 1750 patients, including N = 100 with PMR, who attended our tertiary immuno-rheumatology clinic between January 1, 2005 and November 30, 2012. A rheumatic disease was deemed paraneoplastic if cancer had been diagnosed in the 2 years preceding or following its onset. The probability of a significant association between a specific rheumatic disease and cancer was evaluated by computing the odds ratio (OR): N = 702 patients with osteoarthritis serving as controls. Furthermore, clinical features distinguishing paraneoplastic rheumatic diseases were searched for by univariate and multivariate analysis. Sjogren's syndrome (SS) [OR 3.6 (CI 95% 1.7-7.5)], PMR (OR 5.1 CI 95% 2.9-8.9), dermatomyositis/polymyositis [OR 12.09 (CI 95% 2.6-55.8)] and vasculitis [OR 3.70 (CI 95% 1.81-7.52)] are associated with cancer. At multivariate analysis, older age is associated with cancer among SS patients (p = 0.03), while in the PMR group, older age, male gender, and ≥6 tender joints are independent predictors of paraneoplastic PMR (p PMR. Older age, male gender and a more extensive joint involvement should be considered red flags for paraneoplastic PMR.

    The management of colorectal cancer increasingly involves multidisciplinary tumor boards. In cases where these occur, the quality can be variable. Despite this, there are no uniform measures to evaluate them. The aim of this study was to evaluate the performance of colorectal cancer tumor boards, via real-time prospective observation. An observational tool, termed Colorectal Multidisciplinary Team Metric for Observation of Decision-Making (cMDT-MODe), was used to assess decision-making in 267 cases. The presentation of case history, radiological and pathological information, as well as contributions to decision making of the various team members were analyzed using descriptive statistics and t-tests. Interobserver agreement was assessed using intraclasscorrelation coefficients. Tumor board meetings lasted 76 min, were attended by approximately 16 specialists each, and reviewed an average of 24 cancer cases (3 min per case review). Regarding the quality of presented information to the team, case history information was rated the highest (mean 4.57), followed by radiological information (mean 4.22) and pathological information (mean 3.81). Regarding each team-member's contribution to discussion, surgeons were scored the highest (mean 4.81), followed by radiologists (mean 4.41) and meeting chairs (mean 4.13)--all team members except the board coordinators were scored highly. Overall scoring reliability was good (0.79). The cMDT-MODe instrument can be reliably used to prospectively assess decision making in the multidisciplinary management of colorectal patients. By systematically quantifying the quality of a colorectal cancer tumor board, we can identify areas for improving practice so as to optimize decision making for cancer care.

  18. Supplementary Golay pair for range side lobe suppression in dual-frequency tissue harmonic imaging.

    2015-02-01

    In dual-frequency (DF) harmonic imaging, the second harmonic signal at second harmonic (2f0) frequency and the inter-modulation harmonic signal at fundamental (f0) frequency are simultaneously imaged for spectral compounding. When the phase-encoded Golay pair is utilized to improve the harmonic signal-to-noise ratio (SNR), however, the DF imaging suffers from range side lobe artifacts due to spectral cross-talk with other harmonic components at DC and third harmonic (3f0) frequency. In this study, a supplementary Golay pair is developed to suppress the range side lobes in combination with the original Golay pair. Since the phase code of the DC interference cannot be manipulated, the supplementary Golay is designed to reverse the polarity of the 3f0 interference and the f0 signal while keeping the 2f0 signal unchanged. For 2f0 imaging, the echo summation of the supplementary and the original Golay can cancel the 3f0 interference. On the contrary, the echo difference between the two Golay pairs can eliminate the DC interference for f0 imaging. Hydrophone measurements indicate that the range side lobe level (RSLL) increases with the signal bandwidth of DF harmonic imaging. By using the combination of the two Golay pairs, the achievable suppression of RSLL can be 3 and 14 dB, respectively for the f0 and 2f0 harmonic signal. B-mode phantom imaging also verifies the presence of range side lobe artifacts when only the original Golay pair is utilized. In combination with the supplementary Golay pair, the artifacts are effectively suppressed. The corresponding range side lobe magnitude reduces by about 8 dB in 2f0 imaging but remains unchanged in f0 imaging. Meanwhile, the harmonic SNR improves by 8-10 dB and the contrast-to-noise ratio of harmonic image increases from about 1 to 1.2 by spectral compounding. For DF tissue harmonic imaging, the spectral cross-talk in Golay excitation results in severe range side lobe artifacts. To restore the image quality, two particular

    Advanced cancer is a risk factor for venous thromboembolism. However, lymph node metastases are usually not considered an established risk factor. In the framework of the prospective, observational Vienna Cancer and Thrombosis Study we investigated the association between local (N0), regional (N1–3), and distant (M1) cancer stages and the occurrence of venous thromboembolism. Furthermore, we were specifically interested in the relationship between stage and biomarkers that have been reported to be associated with venous thromboembolism. We followed 832 patients with solid tumors for a median of 527 days. The study end-point was symptomatic venous thromboembolism. At study inclusion, 241 patients had local, 138 regional, and 453 distant stage cancer. The cumulative probability of venous thromboembolism after 6 months in patients with local, regional and distant stage cancer was 2.1%, 6.5% and 6.0%, respectively (P=0.002). Compared to patients with local stage disease, patients with regional and distant stage disease had a significantly higher risk of venous thromboembolism in multivariable Cox-regression analysis including age, newly diagnosed cancer (versus progression of disease), surgery, radiotherapy, and chemotherapy (regional: HR=3.7, 95% CI: 1.5–9.6; distant: HR=5.4, 95% CI: 2.3–12.9). Furthermore, patients with regional or distant stage disease had significantly higher levels of D-dimer, factor VIII, and platelets, and lower hemoglobin levels than those with local stage disease. These results demonstrate an increased risk of venous thromboembolism in patients with regional disease. Elevated levels of predictive biomarkers in patients with regional disease underpin the results and are in line with the activation of the hemostatic system in the early phase of metastatic dissemination.

    Full Text Available To reduce the number of unnecessary biopsies in patients with benign prostatic disease, however, without missing significant PCa the present study re-evaluates the age-dependent PSA cut-offs in the Tyrol Prostate Cancer (PCa early detection program.The study population included 2225 patients who underwent prostate biopsy due to elevated PSA levels at our department. We divided our patient collective into four age groups: ≤49 years (n = 178, 50-59 years (n = 597, 60-69 years (n = 962 and ≥70 years (n = 488. We simulated different scenarios for PSA cut-off values between 1.25 and 6 ng/mL and fPSA% between 15 and 21% for all four age groups and calculated sensitivity, specificity, confidence intervals and predictive values.PCa was detected in 1218 men (54.7%. We found that in combination with free PSA ≤21% the following PSA cut-offs had the best cancer specificity: 1.75 ng/ml for men ≤49 years and 50-59 years, 2.25 ng/ml for men aged 60-69 years and 3.25 ng/ml for men ≥70 years. Using these adjusted PSA cut-off values all significant tumors are recognized in all age groups, yet the number of biopsies is reduced. Overall, one biopsy is avoided in 13 to 14 men (number needed to screen = 13.3, reduction of biopsies = 7.5% when decision regarding biopsy is done according to the "new" cut-off values instead of the "old" ones. For the different age groups the number needed to screen to avoid one biopsy varied between 9.2 (≤49 years and 17.4 (50-59 years.With "new", fine-tuned PSA cut-offs we detect all relevant PCa with a significant reduction of biopsies compared to the "old" cut-off values. Optimization of age-specific PSA cut-offs is one step towards a smarter strategy in the Tyrol PCa Early Detection Program.

    Full Text Available Abstract Background Non-melanoma skin cancer (NMSC is the most frequent tumour among Caucasian populations worldwide. Among the risk factors associated with this tumour, there are host-related factors and several environmental agents. A greater likelihood of high exposure to physical agents (with the exception of solar radiation and chemical agents depends on the work setting. Our objective is to evaluate the role of occupational exposures in NMSC, with special emphasis on risk factors other than solar radiation and skin type. Methods We analysed 1585 cases (1333 basal cell carcinoma (BCC and 183 squamous cell carcinoma (SCC and 1507 controls drawn from the Helios-I multicenter study. Odds ratios (OR and 95% confidence intervals (CI were estimated using logistic regression mixed models. Results For NMSC as a whole (both histological types, miners and quarrymen, secondary education teachers, and masons registered excess risk, regardless of exposure to solar radiation and skin type (OR 7.04, 95% CI 2.44–20.31; OR 1.75, 95% CI 1.05–2.89 and OR 1.54, 95% CI 1.04–2.27, respectively. Frequency of BCC proved higher among railway engine drivers and firemen (OR 4.55; 95% CI 0.96–21.57, specialised farmers (OR 1.65; 95% CI 1.05–2.59 and salesmen (OR 3.02; 95% CI 1.05–2.86, in addition to miners and quarrymen and secondary education teachers (OR 7.96; 95% CI 2.72–23.23 and OR 1.76; 95% CI 1.05–2.94 respectively. The occupations that registered a higher risk of SCC (though not of BCC were those involving direct contact with livestock, construction workers not elsewhere classified (OR 2.95, 95% CI 1.12–7.74, stationary engine and related equipment operators not elsewhere classified (OR 5.31, 95% CI 1.13–21.04 and masons (OR 2.55, 95% CI 1.36–4.78. Conclusion Exposure to hazardous air pollutants, arsenic, ionizing radiations and burns may explain a good part of the associations observed in this study. The Helios study affords an

    Full Text Available Background. The paper presents our own experience of using a waterjet dissector ERBEJET2® in the course of surgical interventions for colorectal cancer. This experience is unique for Russia.Materials and methods. Waterjet dissection method associated with total  mesorectumectomy was used by us in 20 patients suffering from rectal cancer. An average age of patients was 59.2 ± 13.9 years. In all the patients surgeries were performed for adenogenic colorectal cancer, morphologically verified at the preoperative stage. Resected preparations were studied on morphological level. For comparison, two control groups of 20 patients were selected, in which the rectum mobilization was performed by using monopolar coagulator and harmonic scalpel. The studied groups were matched by gender, age, location and the tumor extent. All the surgeries were performed by one surgical team.Results. Results of the study demonstrated advantages of waterjet dissection when performing total mesorectumectomy due to a minimum depth of tissue damage on the lateral margin of resection.Conclusion. Waterjet dissectors have taken their place in the extensive list of tools used when performing surgical interventions for colorectal cancer, that allows to expect an improvement of functional and oncological results of the surgical treatment.

    To investigate the role of occupational exposure to endotoxins in lung cancer in a French population-based case-control study (ICARE (Investigation of occupational and environmental causes of respiratory cancers)). Detailed information was collected on the occupational history and smoking habits from 2926 patients with histologically confirmed lung cancer and 3555 matched controls. We evaluated each subject's endotoxin exposure after cross referencing International Standard Classification of Occupations (ISCO) codes (for job tasks) and Nomenclature d'Activités Françaises (NAF) codes (for activity sectors). Endotoxin exposure levels were attributed to each work environment based on literature reports. ORs and 95% CIs were estimated using unconditional logistic regression models and controlled for main confounding factors. An inverse association between exposure to endotoxins and lung cancer was found (OR=0.80, 95% CI 0.66 to 0.95). Negative trends were shown with duration and cumulative exposure, and the risk was decreased decades after exposure cessation (all statistically significant). Lung cancer risk was particularly reduced among workers highly exposed (eg, in dairy, cattle, poultry, pig farms), but also in those weakly exposed (eg, in waste treatment). Statistically significant interactions were shown with smoking, and never/light smokers were more sensitive to an endotoxin effect than heavy smokers (eg, OR=0.14, 95% CI 0.06 to 0.32 and OR=0.80, 95% CI 0.45 to 1.40, respectively, for the quartiles with the highest cumulative exposure, compared with those never exposed). Pronounced inverse associations were shown with adenocarcinoma histological subtype (OR=0.37, 95% CI 0.25 to 0.55 in the highly exposed). Our findings suggest that exposure to endotoxins, even at a low level, reduces the risk of lung cancer. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Breast conserving surgery (BCS) followed by chemotherapy (CT{sub x}.) and radiation therapy (RT) is widely performed for the treatment of early breast cancer. This retrospective study was undertaken to evaluate our interim results in terms of failure patterns, survival and relative risk factors. From January 1999 through December 2003, 129 patients diagnosed with invasive breast cancer and treated with BCS followed by RT were subject to retrospective review. The median age of the patients was 45 years (age distribution, 27 {approx} 76 years). The proportions of patients according to their tumor, nodes, and metastases (TNM) stage were 65 (50.4%) in stage I, 41 (31.7%) in stage IIa, 13 (10.1%) in stage IIb, 9 (7.0%) in stage III, and 1 patient (0.8%) in stage IIIc. For 32 patients (24.8%), axillary node metastasis was found after dissection, BCS consisted of quadrantectomy in 115 patients (89.1%) and lumpectomy in 14 patients (10.6%). Axillary node dissection at axillary level I and II was performed for 120 patients (93%). For 7 patients (5.4%), only sentinel node dissection was performed with BCS. For 2 patients (1.6%) axillary dissection of any type was not performed. Postoperative RT was given with 6 MV X-rays. A tumor dose of 50.4 Gy was delivered to the entire breast area using a tangential field with a wedge compensator. An additional dose of 9 {approx} 16 Gy was given to the primary tumor bed areas with electron beams. In 30 patients (23.3%), RT was delivered to the supraclavicular node. Most patients had adjuvant CT{sub x}. with 4 {approx} 6 cycles of CMF (cyclophosphamide, methotrexate, 5-fluorouracil) regimens. The median follow-up period was 50 months (range: 17 {approx} 93 months). The actuarial 5 year survival rate (5Y-OSR) was 96.9%, and the 5 year disease free survival rate (5Y-DFSR) was 93.7%. Local recurrences were noted in 2 patients (true: 2, regional node: 1) as the first sign of recurrence at a mean time of 29.3 months after surgery. Five

    Purpose: To evaluate acute toxicity and efficacy of simultaneous radiochemotherapy for invasive urothelial cancer of the bladder. Patients and Methods: From September 1993 to July 1997, 61 patients with invasive bladder cancer were treated with a transurethral resection (TURB) followed by radiochemotherapy (RCT). Twenty-five received a combination of 5-FU and cisplatin. The prescribed doses were 600 mg/m{sup 2} 5-FU daily as continuous infusion over 5 days each in the 1st and 5th treatment week and 20 mg/m{sup 2} cisplatin daily at the same days as a short infusion. The pelvis was irradiated with 54 Gy, the bladder with 59.4 Gy and the paraortic nodes in 7 cases with 45 Gy, respectively. Six to 8 weeks after RCT a second TURB was performed for reasons of restaging. Results: Twenty out of 25 patients received at least 80% of the prescribed chemotherapy, in 13 cases the full dose could be given. Gastrointestinal toxicity of Grade I and II occurred in 10 cases, 1 patient developed severe diarrhea (Grade VI). After the 1st course of chemotherapy 7 patients had leuco- or thrombopenia of Grade III. One patient had a leucopenia of Grade IV. After the 2nd course 4 patients developed Grade III leuko- and thrombopenia, 1 of Grade IV. Two Grade II anemia were found. All more severe toxicities and necessary dose reductions were related to radiation of the paraaortic nodes. No life threatening infections, bleedings or cardiotoxicity was found. Restaging TURBs resulted in 22 complete remissions, 1 patient had a de-novo-carcinoma (Tis) at this time, 2 were non-responders (8%). After a median follow-up of 38 months 20 patients are alive (80%). Conclusions: 1. If irradiation of paraaortic nodes is necessary, 5-FU should not be applied, because the gastrointestinal toxicity is too extensive. In all other cases side effects are tolerable and can be managed by supportive care. 2. The first results are promising and should be evaluated in a prospective study. (orig.) [Deutsch

    A regional supplementary comparison APMP.AUV.A-S1 has been carried out for the measurement of sound pressure level, frequency and total distortion of a multi-frequency sound calibrator. The role of the Pilot laboratory was undertaken by the National Institute of Metrology (Thailand) (NIMT). The multi-frequency sound calibrator was circulated through thirteen National Metrology Institutes (NMIs). Two NMIs were added to the original time schedule after starting the circulation. The measurements took place between September 2008 and July 2010. This report includes the measurement results from all the participants. Supplementary Comparison Reference Values (SCRVs) have been determined from the results. Deviations from the SCRVs are mostly within declared expanded uncertainties. It has been found that a term for the inherent instability in this type of device needs to be included in any uncertainty budget, and a recommended minimum value of this has been given. Main text.

    We investigated the beneficial effects of drinking supplementary water during the school day on the cognitive performance and transitory subjective states, such as fatigue or vigor, in 168 children aged between 9 and 11years who were living in a hot climate (South Italy, Sardinia). The classes were randomly divided into an intervention group, which received water supplementation, and a control group. Dehydration was determined by urine sampling and was defined as urine osmolality greater than 800mOsm/kg H(2)O (Katz, Massry, Agomn, & Toor, 1965). The change in the scores from the morning to the afternoon of hydration levels, cognitive performance and transitory subjective states were correlated. In line with a previous observational study that evaluated the hydration status of school children living in a country with a hot climate (Bar-David, Urkin, & Kozminsky, 2005), our results showed that a remarkable proportion of children were in a state of mild, voluntary dehydration at the beginning of the school day (84%). We found a significant negative correlation between dehydration and the auditory number span, which indicates a beneficial effect of drinking supplementary water at school on short-term memory. Moreover, there was a positive correlation between dehydration and performance in the verbal analogy task. The results are discussed in the light of the complexity of the neurobiological mechanisms involved in the relationship between hydration status and cognition.

    To provide insight into cancer registration coverage, data access and use in Europe. This contributes to data and infrastructure harmonisation and will foster a more prominent role of cancer registries (CRs) within public health, clinical policy and cancer research, whether within or outside the European Research Area. During 2010-12 an extensive survey of cancer registration practices and data use was conducted among 161 population-based CRs across Europe. Responding registries (66%) operated in 33 countries, including 23 with national coverage. Population-based oncological surveillance started during the 1940-50s in the northwest of Europe and from the 1970s to 1990s in other regions. The European Union (EU) protection regulations affected data access, especially in Germany and France, but less in the Netherlands or Belgium. Regular reports were produced by CRs on incidence rates (95%), survival (60%) and stage for selected tumours (80%). Evaluation of cancer control and quality of care remained modest except in a few dedicated CRs. Variables evaluated were support of clinical audits, monitoring adherence to clinical guidelines, improvement of cancer care and evaluation of mass cancer screening. Evaluation of diagnostic imaging tools was only occasional. Most population-based CRs are well equipped for strengthening cancer surveillance across Europe. Data quality and intensity of use depend on the role the cancer registry plays in the politico, oncomedical and public health setting within the country. Standard registration methodology could therefore not be translated to equivalent advances in cancer prevention and mass screening, quality of care, translational research of prognosis and survivorship across Europe. Further European collaboration remains essential to ensure access to data and comparability of the results. Copyright © 2014 Elsevier Ltd. All rights reserved.

    In 1990, GISMa (Italian Group for planning and evaluating Mammographic Screening - Gruppo Italiano per la pianificazione e la valutazione dei programmi di Screening Mammografico), a working group of operators (radiographers, radiologists, epidemiologists, clinicians, surgeons) involved in screening programmes ongoing in Italy, was created within the Italian School of Senology. The aim of this study is to illustrate data, presented at the GISMa meeting held in April 1994, concerning the characteristics of each programme and some early indicators of effectiveness. To assess these parameters (concerning compliance level, recall rate, benign/malignant biopsy ratio, detection rate, stage distribution, nodal involvement and number of cancers with a diameter under 1 cm, rate of cancer, etc.), 'acceptable' and 'desirable' standards obtained from Italian and North-European cancer screening experiences have been adopted. Most programmes have shown an acceptable standard for most of the indicators, and many of them have attained desirable levels. In most screening programmes the occurrence of interval cancers has not yet been measured, but all centres have (or are working to set up) a systematic active procedure to collect the data. The results indicate that common guidelines can be adopted, even when working in very heterogeneous contexts, and that it is possible to achieve a very high effectiveness and efficacy level. As regards quality control and cost/benefit issues, the goal of extending centralised, population-based screening programmes to other Italian regions becomes a priority.

    What do adolescent and young adult survivors of childhood cancer think about the risk of being infertile? The potential infertility, as well as the experience of having had cancer, affects well-being, intimate relationships and the desire to have children in the future. Many childhood cancer survivors want to have children and worry about possible infertility. For this qualitative study with a cross-sectional design, data were collected through 39 online focus group discussions during 2013. Cancer survivors previously treated for selected diagnoses were identified from The Swedish Childhood Cancer Register (16-24 years old at inclusion, ≥5 years after diagnosis) and approached regarding study participation. Online focus group discussions of mixed sex (n = 133) were performed on a chat platform in real time. Texts from the group discussions were analysed using qualitative content analysis. The analysis resulted in the main category Is it possible to have a baby? including five generic categories: Risk of infertility affects well-being, Dealing with possible infertility, Disclosure of possible infertility is a challenge, Issues related to heredity and Parenthood may be affected. The risk of infertility was described as having a negative impact on well-being and intimate relationships. Furthermore, the participants described hesitation about becoming a parent due to perceived or anticipated physical and psychological consequences of having had cancer. Given the sensitive topic of the study, the response rate (36%) is considered acceptable. The sample included participants who varied with regard to received fertility-related information, current fertility status and concerns related to the risk of being infertile. The results may be transferred to similar contexts with other groups of patients of childbearing age and a risk of impaired fertility due to disease. The findings imply that achieving parenthood, whether or not with biological children, is an area that

    To evaluate the diagnostic performance of dual energy (DE) perfusion-CT for the differentiation between postoperative soft-tissue formation and tumor recurrence in patients after potentially curative pancreatic cancer resection. 24 patients with postoperative soft-tissue formation in the conventional regular follow-up CT acquisition after pancreatic cancer resection with curative intent were included prospectively. They were examined with a 64-row dual-source CT using a dynamic sequence of 34 DE acquisitions every 1.5 s (80 ml of iodinated contrast material, 370 mg/ml, flow rate 5 ml/s). Weighted average (linearly blended M0.5) 120 kVp-equivalent dual-energy perfusion image data sets were evaluated with a body-perfusion CT tool for estimating blood flow, permeability, and blood volume. Diagnosis was confirmed by histological study (n=4) and by regular follow-up. Final diagnosis was local recurrence of pancreatic cancer in 15 patients and unspecific postoperative tissue formation in 9 patients. The blood-flow values for recurrence tissue trended to be lower compared to postoperative tissue formation with 16.6 ml/100 ml/min and 24.7 ml/100 ml/min, respectively for weighted average 120 kVp-equivalent image data, which was not significant (n.s.) (p=0.06, significance level 0.05). Permeability- and blood-volume values were only slightly lower in recurrence tissue (n.s.). DE perfusion-CT is feasible in patients after pancreatic cancer resection and a promising functional imaging technique. As only a trend for lower perfusion values in local recurrence compared to unspecific postoperative alterations was found, the perfusion differences are not yet sufficient to differentiate between malignancy and unspecific postoperative alterations for this new technique. Further studies and technical improvements are needed to generate reliable data for this clinically highly relevant differentiation.

    The most deadly phase in cancer progression is attributed to the inappropriate acquisition of molecular machinery leading to metastatic transformation and spread of disease to distant organs. Although it is appreciated that metastasis involves epithelial-mesenchymal interplay, the underlying mechanism defining this process is poorly understood. Specifically, how cancer cells evade immune surveillance and gain the ability to navigate the circulatory system remains a focus. One possible mechanism underlying metastatic conversion is fusion between blood-derived immune cells and cancer cells. While this notion is a century old, in vivo evidence that cell fusion occurs within tumors and imparts genetic or physiologic changes remains controversial. We have previously demonstrated in vivo cell fusion between blood cells and intestinal epithelial cells in an injury setting. Here, we hypothesize that immune cells, such as macrophages, fuse with tumor cells imparting metastatic capabilities by transferring their cellular identity. We used parabiosis to introduce fluorescent-labeled bone marrow-derived cells to mice with intestinal tumors, finding that fusion between circulating blood-derived cells and tumor epithelium occurs during the natural course of tumorigenesis. Moreover, we identify the macrophage as a key cellular partner for this process. Interestingly, cell fusion hybrids retain a transcriptome identity characteristic of both parental derivatives, while also expressing a unique subset of transcripts. Our data supports the novel possibility that tumorigenic cell fusion may impart physical behavior attributed to migratory macrophages, including navigation of circulation and immune evasion. As such, cell fusion may represent a promising novel mechanism underlying the metastatic conversion of cancer cells.

    To evaluate the impact of radiological expertise on screen result decisions in a CT lung cancer screening trial. In the NELSON lung cancer screening trial, the baseline CT result was based on the largest lung nodule's volume. The protocol allowed radiologists to manually adjust screen results in cases of high suspicion of benign or malignant nodule nature. Participants whose baseline CT result was based on a solid or part-solid nodule were included in this study. Adjustments by radiologists at baseline were evaluated. Histology was the reference for diagnosis or to confirm benignity and stability on subsequent CT examinations. A total of 3,318 participants (2,796 male, median age 58.0 years) were included. In 195 participants (5.9 %) the initial baseline screen result was adjusted by the radiologist. Adjustment was downwards from positive or indeterminate to negative in two and 119 participants, respectively, and from positive to indeterminate in 65 participants. None of these nodules turned out to be malignant. In 9/195 participants (4.6 %) the screen result was adjusted upwards from negative to indeterminate or indeterminate to positive; two nodules were malignant. In one in 20 cases of baseline lung cancer screening, nodules were reclassified by the radiologist, leading to a reduction of false-positive screen results. (orig.)

    With rising cure rates of childhood cancer, side effects of treatment are attracting increasing interest. The present analysis evaluates the influence of tumor localization, radiotherapy and chemotherapy on the age of menarche. 4,689 former pediatric oncology patients, diagnosed 1980-2004, were contacted in collaboration with the German Childhood Cancer Registry. 1,036 out of 1,461 female participants reported their age at menarche and had an oncological diagnosis before menarche. The median age at menarche was 13 years, compared to 12.8 years in the German general population. A significant delay of menarche was seen in patients with pituitary radiation doses of ≥30 Gy (mean 13.6 years, SD 2.2) compared to <30 Gy (mean 12.5 years, SD 1.4, p = 0.05). Patients with additional spinal radiation were even older at menarche (mean 14.4 years, SD 2.5). Pelvic and pelvic-near radiation significantly delayed onset of menarche (mean 14.0 years, SD 1.9 and mean 14.3, SD 2.6, respectively, p < 0.001). Only some chemotherapeutic agents (carboplatin/cisplatin, etoposide) were associated with a menarcheal delay of <1 year. Overall, female childhood cancer survivors showed a normal menarcheal age. Pituitary radiation dosage of ≥30 Gy, spinal and pelvic radiotherapy were associated with a moderate delay in the occurrence of menarche. Copyright © 2012 S. Karger AG, Basel.

    Endometrial cancer risk prediction models including lifestyle, anthropometric and reproductive factors have limited discrimination. Adding biomarker data to these models may improve predictive capacity; to our knowledge, this has not been investigated for endometrial cancer. Using a nested case-control study within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, we investigated the improvement in discrimination gained by adding serum biomarker concentrations to risk estimates derived from an existing risk prediction model based on epidemiologic factors. Serum concentrations of sex steroid hormones, metabolic markers, growth factors, adipokines and cytokines were evaluated in a step-wise backward selection process; biomarkers were retained at p risk estimates. We used internal validation with bootstrapping (1000-fold) to adjust for over-fitting. Adiponectin, estrone, interleukin-1 receptor antagonist, tumor necrosis factor-alpha and triglycerides were selected into the model. After accounting for over-fitting, discrimination was improved by 2.0 percentage points when all evaluated biomarkers were included and 1.7 percentage points in the model including the selected biomarkers. Models including etiologic markers on independent pathways and genetic markers may further improve discrimination. © 2016 UICC.

    Colon cancer (CC) is among the most common malignant diseases with a dismal survival. Tumor necrosis factor-alpha (TNF-α) has been identified as a therapeutic target in various cancers, and anti-TNF-α treatment has shown promising effects in different cancer models. However, if TNF-α can be targeted in CC, the therapeutic values of anti-TNF-α treatment in CC remain unknown. Our study indicated that TNF-α is highly expressed in CC cell lines and patient tumor samples. High expression of TNF-α is an independent adverse prognosticator of CC. Targeting the TNF-α by its antibody infliximab induced antibody-dependent cellular cytotoxicity and complement-dependent cytotoxicity and enhanced apoptosis leading to cell death. The combination of infliximab with 5-fluorouracil showed better responses in vitro and in vivo than 5-fluorouracil alone. In conclusion, this study identified TNF-α as a target of CC and anti-TNF-α treatment synergized with chemotherapy leading to a better outcome in preclinical models. PMID:27757041

    Activity circadian rhythms were measured non-invasively in 30 patients with metastatic colorectal cancer by wrist actigraphy, and compared with control data. Patients and control subjects were requested to wear the actigraph at home for 2 to 5 days. Control time-series exhibit high activity levels (150 to 350 counts/min) during daytime, followed by low activity levels (0 to 50 counts/min) during the night. In patients, the contrast between daytime activity and nocturnal sleep is noticeably less marked, and a wide inter-patient variability can be observed. This alteration of the rest-activity rhythm in the cancer group was statistically validated by autocorrelation test. Results from the cosinor and he maximal entropy spectral analysis must be interpreted more cautiously, since the prerequisites for these tests may not be fulfilled by actometric time-series. These results indicate that cancer patients may have altered rest-activity circadian rhythms. The significance and prognostic value of such alterations deserve further testing in a larger population. Actigraphy may provide a simple and innovative tool to study the circadian system in cancer patients.

    Our laboratory has focused on the development of ultrasound tomography (UST) for breast imaging. To that end we have been developing and testing a clinical prototype in the Karmanos Cancer Institute's (KCI) breast center. The development of our prototype has been guided by clinical feedback from data accumulated from over 300 patients recruited over the last 4 years. Our techniques generate whole breast reflection images as well as images of the acoustic parameters of sound speed and attenuation. The combination of these images reveals major breast anatomy, including fat, parenchyma, fibrous stroma and masses. Fusion imaging, utilizing thresholding, is shown to visualize mass characterization and facilitates separation of cancer from benign masses. These results indicate that operator-independent whole-breast imaging and the detection and characterization of cancerous breast masses are feasible using acoustic tomography techniques. Analyses of the prototype images suggests that we can detect the variety of mass attributes noted by current ultrasound-BIRADS criteria, such as mass shape, acoustic mass properties and architecture of the tumor environment. These attributes help quantify current BIRADS criteria (e.g. "shadowing" or high attenuation) and provide greater possibilities for defining a unique signature of cancer. The potential for UST to detect and characterize breast masses was quantified using UST measurements of 86 masses from the most recent cohort of patients imaged with the latest version of our prototype. Our preliminary results suggest that the development of a formal predictive model, in support of larger future trials, is warranted.

    Male breast cancer is a rare malignancy. Despite the lack of prospectively generated data from trials in either the adjuvant or metastatic setting, patients are commonly treated with hormone therapies. Much controversy exists over the use of gonadotropin-releasing hormone analogues in metastatic male breast cancer patients. We conducted this study to provide more concrete ground on the use of gonadotropin-releasing hormone analogues in this setting. We herein present results from a pooled analysis including 60 metastatic male breast cancer patients treated with either an aromatase inhibitor or cyproterone acetate as a monotherapy (23 patients) or combined with a gonadotropin-releasing hormone analogue (37 patients). Overall response rate was 43.5% in patients treated with monotherapy and 51.3% with combination therapy (p = 0.6). Survival outcomes favored combination therapy in terms of median progression-free survival (11.6 months versus 6 months; p = 0.05), 1-year progression-free survival rate (43.2% versus 21.7%; p = 0.05), median overall survival (29.7 months versus 22 months; p = 0.05), and 2-year survival rate (64.9% versus 43.5%; p = 0.05). In metastatic male breast cancer patients, the combined use of gonadotropin-releasing hormone analogues and aromatase inhibitors or antiandrogens seems to be associated with greater efficacy, particularly in terms of survival outcomes, compared with monotherapy. Collectively, these results encourage considering these agents in the metastatic setting.

    A previous study showed promising results for gadofosveset-trisodium as a lymph node magnetic resonance imaging (MRI) contrast agent in rectal cancer. The aim of this study was to prospectively confirm the diagnostic performance of gadofosveset MRI for nodal (re)staging in rectal cancer in a second patient cohort. Seventy-one rectal cancer patients were prospectively included, of whom 13 (group I) underwent a primary staging gadofosveset MRI (1.5-T) followed by surgery (± preoperative 5 x 5 Gy) and 58 (group II) underwent both primary staging and restaging gadofosveset MRI after a long course of chemoradiotherapy followed by surgery. Nodal status was scored as (y)cN0 or (y)cN+ by two independent readers (R1, R2) with different experience levels. Results were correlated with histology on a node-by-node basis. Sensitivity, specificity and area under the receiver operating characteristics curve (AUC) were 94 %, 79 % and 0.89 for the more experienced R1 and 50 %, 83 % and 0.74 for the non-experienced R2. R2's performance improved considerably after a learning curve, to an AUC of 0.83. Misinterpretations mainly occurred in nodes located in the superior mesorectum, nodes located in between vessels and nodes containing micrometastases. This prospective study confirms the good diagnostic performance of gadofosveset MRI for nodal (re)staging in rectal cancer. (orig.)

    Breast cancer screening is offered to 100% of the target population in Spain and intermediate mammograms (IMs) are sometimes indicated. This study was aimed at analysing the frequency of IMs, the factors determining their recommendation, and their impact on the risk of false-positive results and the detection rate. Data from 3,471,307 mammograms from Spanish breast cancer screening programmes were included. 3.36% of the mammograms were IMs. The factors associated with the use of IMs were age, initial screening, previous invasive tests, a familial history of breast cancer and use of hormone replacement therapy. In screening episodes with an IM, the probability of a false-positive result was 13.74% (95% CI: 13.43-14.05), almost double that in episodes without IMs (6.02%, 95% CI 5.99-6.05). In young women with previous invasive procedures, a familial history of breast cancer or hormone replacement therapy use who were undergoing their initial screen, this probability was lower when IMs were performed. IMs always increased the detection rate. The factors prompting IMs should be characterised so that radiologists can systematise their recommendations according to the presence of the factors maximising the benefits and minimising the adverse effects of this procedure.

    There is sparse data on the analysis of supplementary motor area in language function using direct cortical stimulation of the supplementary motor area. Here, we report a patient who experienced isolated anomia during stimulation of the anterior supplementary motor area and discuss the role of the supplementary motor area in speech production. The role of the pre-supplementary motor· area in word selection, observed in fMRI studies, can be confirmed by direct cortical stimulation.

    Full Text Available Abstract Background The palliative services and programs have been developed with different intensity and modalities in all countries. Several studies have reported that a geographic variation in the availability and provision of palliative care services between and within countries exists, and that a number of vulnerable groups are excluded from these services. This survey estimates the distribution of places of care for Italian cancer patients during the last three months of their lives, the proportion receiving palliative care support at home and in hospital, and the factors associated with the referral to palliative care services. Methods This is a mortality follow-back survey of 2,000 cancer deaths identified with a 2-stage probability sample, representative of the whole country. Information on patients' experience was gathered from the non-professional caregiver through an interview, using an adapted version of the VOICES questionnaire. A section of the interview concerned the places of care and the palliative care services provided to patients. Multivariate logistic regression analyses were conducted to identify the determinants of palliative care service use. Results Valid interviews were obtained for 67% of the identified caregivers (n = 1,271. Most Italian cancer patients were cared for at home (91% or in hospital (63%, but with substantial differences within the country. Only 14% of Italian cancer patients cared for at home against 20% of those admitted to hospital, received palliative care support. The principal determinants identified for receiving these service were: an extended interval between diagnosis and death (P = 0.01 and the caregiver's high educational level (P = 0.01 for patients at home; the low patient's age (P Conclusion In Italy palliative care services are not equally available across the country. Moreover, access to the palliative care services is strongly associated with socio demographic characteristics of the

    Appropriate utilization of treatment is a goal for all patients undergoing cancer treatment. Proper treatment maximizes benefit and limits exposure to unnecessary measures. This report describes findings of the feasibility and acceptability of implementing a short, clinic-based decision aid and presents an in-depth clinical profile of the participants. This descriptive study used a prospective, quantitative approach to obtain the feasibility and acceptability of a decision aid (DecisionKEYS for Balancing Choices) for use in clinical settings. It combined results of trials of patients with three different common malignancies. All groups used the same decision aid series. Participants included 80 patients with solid tumors (22 with newly diagnosed breast cancer, 19 with advanced prostate cancer, and 39 with advanced lung cancer) and their 80 supporters as well as their physicians and nurses, for a total of 160 participants and 10 health professionals. The decision aid was highly acceptable to patient and supporter participants in all diagnostic groups. It was feasible for use in clinic settings; the overall value was rated highly. Of six physicians, all found the interactive format with the help of the nurse as feasible and acceptable. Nurses also rated the decision aid favorably. This intervention provides the opportunity to enhance decision making about cancer treatment and warrants further study including larger and more diverse groups. Strengths of the study included a theoretical grounding, feasibility testing of a practical clinic-based intervention, and summative evaluation of acceptability of the intervention by patient and supporter pairs. Further research also is needed to test the effectiveness of the decision aid in diverse clinical settings and to determine if this intervention can decrease overall costs.

    Prospective studies examining the association between coffee and tea consumption and gastric cancer risk have shown inconsistent results. We investigated the association between coffee (total, caffeinated and decaffeinated) and tea consumption and the risk of gastric cancer by anatomical site and histological type in the European Prospective Investigation into Cancer and Nutrition study. Coffee and tea consumption were assessed by dietary questionnaires at baseline. Adjusted hazard ratios (HRs) were calculated using Cox regression models. During 11.6 years of follow up, 683 gastric adenocarcinoma cases were identified among 477,312 participants. We found no significant association between overall gastric cancer risk and consumption of total coffee (HR 1.09, 95%-confidence intervals [CI]: 0.84-1.43; quartile 4 vs. non/quartile 1), caffeinated coffee (HR 1.14, 95%-CI: 0.82-1.59; quartile 4 vs. non/quartile 1), decaffeinated coffee (HR 1.07, 95%-CI: 0.75-1.53; tertile 3 vs. non/tertile 1) and tea (HR 0.81, 95%-CI: 0.59-1.09; quartile 4 vs. non/quartile 1). When stratified by anatomical site, we observed a significant positive association between gastric cardia cancer risk and total coffee consumption per increment of 100 mL/day (HR 1.06, 95%-CI: 1.03-1.11). Similarly, a significant positive association was observed between gastric cardia cancer risk and caffeinated coffee consumption (HR 1.98, 95%-CI: 1.16-3.36, p-trend=0.06; quartile 3 vs. non/quartile 1) and per increment of 100 mL/day (HR 1.09, 95%-CI: 1.04-1.14). In conclusion, consumption of total, caffeinated and decaffeinated coffee and tea is not associated with overall gastric cancer risk. However, total and caffeinated coffee consumption may be associated with an increased risk of gastric cardia cancer. Further prospective studies are needed to rule out chance or confounding. © 2014 UICC.
