    The dietary intake of 105 adult Dutch Caucasian patients (28 women with endometrial or cervical cancer, 50 men with bladder or prostate cancer and 14 men and 13 women with malignant lymphoma) was studied for 19 weeks. Energy and nutrient intakes of all patients were assessed by a dietary history with cross-check over 2 months prior to treatment and by seven 48-h dietary records filled in just before, during and after cancer therapy. No differences were observed between the results obtained with the dietary history and the first 48-h diary. In females treated with abdominal irradiation the mean daily intake of fat, dietary fibre, iron and thiamin decreased during therapy. In men treated with radiotherapy the intake of vegetable protein, polysaccharides, dietary fibre and thiamin also decreased during treatment. This may be partly explained by the observation that many of these patients had spontaneously chosen a 'constipating diet' because of diarrhoea. As compared with the Dutch Recommended Dietary Allowance only the iron intake of the women gave rise to some concern. In our study we did not observe marked changes in dietary intake and nutritional status. In females who underwent irradiation therapy especially, the dietary intake increased after a period of intensive treatment. This demonstrates that food intake of these groups of cancer patients is not consistently reduced by chemotherapy or even abdominal radiotherapy.

    This study focuses on the association between the ABO blood group system and the risk of gastric cancer or Helicobacter pylori infection. The data for the ABO blood group was collected from 1045 cases of gastric cancer, whereby the patient underwent a gastrectomy in Ruijin Hospital, Shanghai. The information on the ABO blood group from 53,026 healthy blood donors was enrolled as control. We searched the Pubmed database on the relationship between ABO blood groups and gastric cancer risk for meta-analysis. In our case-control study, the risk of gastric cancer in blood group A was significantly higher than that in non-A groups (O, B and AB) (odd ratio, OR1.34; 95% confidential interval, CI 1.25-1.44). Compared with non-O groups (A, B and AB), individuals with blood group O demonstrated a reduced risk of gastric cancer (OR = 0.80; 95% CI 0.72-0.88). The proportion of H. pylori infection in blood group A individuals was significantly higher than that in non-A blood groups (OR = 1.42; 95% CI 1.05-1.93). We further combined our data with the published data of others, and crossreferenced the risk of gastric cancer with the blood type, finding consistent evidence that gastric cancer risk in the blood A group was higher than that in the non-A groups (OR = 1.11; 95% CI 1.07-1.15), and that blood type O individuals were consistently shown gastric cancer risk reduction (OR = 0.91; 95% CI 0.89-0.94). Our study concluded that there was a slightly increased risk of gastric cancer in blood group A individuals, and people with blood type A are more prone to be infected by H. pylori than other ABO blood type individuals, whereas, a slightly decreased risk of gastric cancer was identified in blood type O individuals.

    We report our multicentric experience with sentinel lymph node biopsy for breast cancer patients. Patients with breast cancer operated on from January 1999 to March 2005 in 6 different institutions in the Rome area were retrospectively reviewed. All patients gave written informed consent. 1440 consecutive patients were analysed, with a median age of 59 years (range: 33-81) and a median tumour diameter of 1.3 cm (range: 0.1-5). Patients underwent lymphatic mapping with Tc99 nanocolloid (N = 701; 49%), with Evans Blue (N = 70; 5%), or with a combined injection (N = 669, 46%). The majority of patients were mapped with an intradermal or subdermal injection (N = 1193; 84%), while an intraparenchymal or peritumoral injection was used in 41 (3%) and 206 patients (13%), respectively. Sentinel lymph nodes were identified in 1374/1440 cases (95.4%), and 2075 sentinel lymph nodes were analysed (average 1.5/patient). A total of 9305 additional non-sentinel lymph-nodes were removed (median 6/patient). Correlations between sentinel lymph nodes and final lymph node status were found in 1355/1374 cases (98.6%). There were 19 false-negative cases (5%). Lymph node metastases were diagnosed in 325 patients (24%). In this group, micrometastases (< 2 mm in diameter) were diagnosed in 103 cases (7.6%). Additionally, isolated tumour cells were reported in 61 patients (4,5%). In positive cases, additional metastases in non-sentinel lymph-nodes were identified in 117/325 cases after axillary dissection (36%). Axillary dissection was avoided in 745/1440 patients (52%). At a median follow-up of 36 months, only 1 axillary recurrence has been reported. Sentinel lymph node biopsy improves staging in women with breast cancer because it is accurate and reproducible, and allows detection of micrometastases and isolated tumour cells that would otherwise be missed. Our multicentric study confirms that this is the preferred axillary staging procedure in women with breast cancer.

    Examples of organometallic compounds as nucleoside analogues are rare within the field of medicinal bioorganometallic chemistry. We report on the synthesis and properties of two chiral ferrocene derivatives containing a nucleobase and a hydroxyalkyl group. These so-called ferronucleosides show promising anticancer activity, with cytostatic studies on five different cancer cell lines indicating that both functional groups are required for optimal activity.

    Various research studies have identified the sources and types of support that people with cancer receive; however, few have focused on identifying the specific characteristics of emotional, instrumental, and informational support. In this study, focus groups consisting of Gilda's Club members explored the types of support that people with cancer and their caregivers experienced and valued. Results showed that although men and women with cancer and caregivers identify similar sources of support, they experience different types of support. Results also indicated a desire among participants to help and support others, a concept referred to as generativity. Implications for social workers and health care providers are explored.

    Retrospective study of Cancer types in different ethnic groups & genders determines the pattern of cancers in different ethnic groups & genders during the last eight years reported in Oncology wards of hospitals of Karachi, Pakistan. Every single one male & female case with histologically and cytologically established cancer was enrolled from January 2003 to December 2010. Data for all patients were collected retrospectively by patient's file & charts, which represents the population of Karachi, Interior Sindh & Balochistan. 5134 patients (Male = 2432 / Female = 2702) investigated for their diagnosis of cancer type, ethnicity, age & gender. Classification of malignancy was done according to the International Classification of Disease coding system by W.H.O (ICD-10). The statistical analysis was performed for mean, standard error & proportions for ethnic groups & genders. Proportionately 47.37% males and among which major ethnic groups 17% Sindhi, 17% Immigrant, 4% Baloch, 3% Pukhtoon, ≈ 4% Punjabi, 1% Siraiki, 2% Minorities and 52.62% females, in which 16% Sindhi, 21% Immigrant, 4% Baloch 3% Pukhtoon, 5% Punjabi, 1% Siraiki, 3% Minorities. Mean age of males = 45.75 years, SE ± 0.227 and for females = 44.07, SE ± 0.183. The three most occurring tumors in all cancers of male were found Head & Neck, Adenoma/Carcinoma of Glands & Body cavity membranes, GIT, and females Breast, Head & Neck, Adenoma/Carcinoma of Glands & Body cavity membranes, GIT. The analysis of data indicates Head & Neck is most common cancer among male, in the similar way Breast cancer is the most common malignancy among female.

    Based on the idea that electric light at night might account for a portion of the high and rising risk of breast cancer worldwide, it was predicted long ago that women working a non-day shift would be at higher risk compared with day-working women. This hypothesis has been extended more recently to prostate cancer. On the basis of limited human evidence and sufficient evidence in experimental animals, in 2007 the International Agency for Research on Cancer (IARC) classified 'shift work that involves circadian disruption' as a probable human carcinogen, group 2A. A limitation of the epidemiological studies carried out to date is in the definition of 'shift work.' IARC convened a workshop in April 2009 to consider how 'shift work' should be assessed and what domains of occupational history need to be quantified for more valid studies of shift work and cancer in the future. The working group identified several major domains of non-day shifts and shift schedules that should be captured in future studies: (1) shift system (start time of shift, number of hours per day, rotating or permanent, speed and direction of a rotating system, regular or irregular); (2) years on a particular non-day shift schedule (and cumulative exposure to the shift system over the subject's working life); and (3) shift intensity (time off between successive work days on the shift schedule). The group also recognised that for further domains to be identified, more research needs to be conducted on the impact of various shift schedules and routines on physiological and circadian rhythms of workers in real-world environments.

  12. 2014 Korean Liver Cancer Study Group-National Cancer Center Korea practice guideline for the management of hepatocellular carcinoma.

    2015-01-01

    The guideline for the management of hepatocellular carcinoma (HCC) was first developed in 2003 and revised in 2009 by the Korean Liver Cancer Study Group and the National Cancer Center, Korea. Since then, many studies on HCC have been carried out in Korea and other countries. In particular, a substantial body of knowledge has been accumulated on diagnosis, staging, and treatment specific to Asian characteristics, especially Koreans, prompting the proposal of new strategies. Accordingly, the new guideline presented herein was developed on the basis of recent evidence and expert opinions. The primary targets of this guideline are patients with suspicious or newly diagnosed HCC. This guideline provides recommendations for the initial treatment of patients with newly diagnosed HCC.

    Full Text Available Abstract Background Although treatment regimen have improved in the last few years, prostate cancer patients following a radical prostatectomy still experience severe disease- and treatment-related side effects, including urinary incontinence, erectile dysfunction and psychological issues. Despite high incidence rates and the common adverse effects there is a lack of supportive measures for male patients and specific physical exercise recommendations for prostate cancer patients during rehabilitation or in the aftercare are still missing. Methods/Design The ProRehab Project aims to establish rehabilitative sports groups particularly for prostate cancer patients and to evaluate the effects of the offered exercise program. Starting 8–12 weeks after prostatectomy or combination therapy, prostate cancer patients will exercise for 15 months within a patient preference randomized controlled trial. One exercise session will be conducted within a pre-established rehabilitative sports group, while the other will be completed independently. Patients in the control group will not participate in the intervention. The main outcomes of the study include aerobic fitness, quality of life, incontinence and erectile dysfunction. Discussion By combining science, practice, and public relations the first rehabilitative sports groups for prostate cancer patients in Germany have been set up and thus contribute to the care structure for prostate cancer patients. By offering a 15-month physical exercise intervention that is conducted in supervised group sessions, long-term lifestyle changes and therefore improvements in quality of life in prostate cancer patients can be expected.

    Of 13 cancers that tend to occur at lower rates in aboriginal Americans or in the native lands of Japanese, Chinese, and Spanish-speaking persons than in United States whites, rates for all but one (laryngeal) have increased in migrants to the United States. In addition to leukemia, these 13 cancers include neoplasms that have been related, at least in part, to a diet high in animal fats or proteins (colon and rectum cancer); reproductive and endocrinologic factors and a diet high in animal fats or protein (prostate, ovary, corpus uteri, breast, and testis cancer); chemical carcinogens (lung, larynx, bladder, and pancreas cancer); and a common infectious agent that, like polio viruses, causes clinically overt disease with a frequency directly related to age of patient at initial infection (Hodgkin's disease). Of 9 cancers that occur at higher rates in aboriginal Americans or in one or more of the native lands of migrants than in United States whites, the rates of 5 tend to decrease in migrants. These include cancers that may be related to food preservation (stomach cancer); products of microorganisms that may contaminate foods (esophagus and liver cancer); and infectious agents (nasopharynx, cervix uteri, and liver cancer). In addition, rates of cancer of the thyroid are high in aboriginal Americans; those of the gallbladder are high in individuals of native American ancestry and in Japanese; incidence of salivary gland tumors is high in Alaskan natives and Colombians; and rates of kidney cancer are high in Alaskan natives. Five types of epidemiologic studies are described that should be conducted in the migrants and in their countries of origin and adoption to elucidate further the etiology of various neoplasms.

Study population: All Danish patients with newly diagnosed colorectal cancer who are either diagnosed or treated in a surgical department of a public Danish hospital. Main variables: The database comprises an array of surgical, radiological, oncological, and pathological variables. The surgeons record data such as diagnostics performed, including type and results of radiological examinations, lifestyle factors, comorbidity and performance, treatment including the surgical procedure, urgency of surgery, and intra- and postoperative complications within 30 days after surgery. The pathologists record data such as tumor type, number of lymph nodes and metastatic lymph nodes, surgical margin status, and other pathological risk factors. Descriptive data: The database has had >95% completeness in including patients with colorectal adenocarcinoma with >54,000 patients registered so far with approximately one-third rectal cancers and two-third colon cancers and an overrepresentation of men among rectal cancer patients. The stage distribution has been more or less constant until 2014 with a tendency toward a lower rate of stage IV and higher rate of stage I after introduction of the national screening program in 2014. The 30-day mortality rate after elective surgery has been reduced from >7% in 2001–2003 to <2% since 2013. Conclusion: The database is a national population-based clinical database with high patient and data completeness for the perioperative period

    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.

    Recent research from the United Kingdom (UK) has highlighted some of the differences in breast cancer presentations between women of different ethnic groups. Analysis of a large database showed that Black women of African or Caribbean heritage living in England and Wales are more likely to present with stage 3 or 4 cancer than White British women and less likely to have their cancer detected through screening. In many countries around the world, migrant and cultural minority groups experience social and economic disadvantage and this is reflected in their health outcomes. With world migration at record levels, it is timely to reflect on ethnic disparities and to consider how developed nations can care for their minority groups, which are increasing in number and diversity. These issues and challenges are discussed, using the UK's migrant population and Australia's Indigenous and migrant populations as case studies.

    This study aimed to examine the associations between intakes of various nutrients and food groups and colorectal cancer risk in a case-control study among Koreans aged 20 to 80 years. A total of 150 new cases and 116 controls were recruited with subjects' informed consent. Dietary data were collected using the food frequency questionnaire developed and validated by the Korea Centers for Disease Control and Prevention. Multivariate logistic regression models were used to estimate odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for colorectal cancer incidence. High intakes of total lipid (ORT3 vs T1 = 4.15, 95% CI: 1.33-12.96, p for trend = 0.034), saturated fatty acid (ORT3 vs T1 = 2.96, 95% CI: 1.24-7.04, p for trend = 0.016) and monounsaturated fatty acid (ORT3 vs T1 = 3.04, 95% CI: 1.23-7.54, p for trend = 0.018) were significantly associated with increased incidence of colorectal cancer. High dietary fiber (ORT3 vs T1 = 0.22, 95% CI: 0.08-0.56, p for trend = 0.002) and vitamin C (ORT3 vs T1 = 0.38, 95% CI: 0.14-1.05, p for trend = 0.021) intakes were significantly associated with reduced colorectal cancer incidence.

On the other hand, high intake of traditional rice cake (ORT3 vs T1 = 0.35, 95% CI: 0.14-0.86, p for trend = 0.024) was linked with lower colorectal cancer incidence. In conclusion, eating a diet high in total lipid, saturated fatty acids and monounsaturated fatty acids is associated with higher incidence of colorectal cancer, whereas a diet high in dietary fiber and vitamin C was found to lower the incidence in Korean adults. Interestingly high

    The Mosan Study Group of Pigmented Neoplasms was founded about 15 years ago. It has collected more than 20,000 cutaneous malignancies including melanomas and basal and squamous cell carcinomas. The incidence of these cancers is on the rise in Wallonia. In particular, malignant melanomas represent a spectrum of emerging cancers characterized by a proteiform biological outcome. They mostly affect young women. The major risk factor appears to be iterative and unwise ultraviolet exposures. The prevention of melanomas is basically founded on such a dogma and accordingly relies on sunscreens. However, controversies about their beneficial effects are rife and fueled by axiomas and contradictory sophisms. At the exception of surgery, the therapeutic options for the diverse types of melanomas do not yet fulfill the scope of evidence-based medicine.

    The cytogenetic endpoints in peripheral blood lymphocytes: chromosomal aberrations (CA), sister chromatid exchange (SCE) and micronuclei (MN) are established biomarkers of exposure for mutagens or carcinogens in the work environment. However, it is not clear whether these biomarkers also may serve as biomarkers for genotoxic effects which will result in an enhanced cancer risk. In order to assess this problem, Nordic and Italian cohorts were established, and preliminary results from these two studies indicated a predictive value of CA frequency for cancer risk, whereas no such associations were observed for SCE or MN. A collaborative study between the Nordic and Italian research groups, will enable a more thorough evaluation of the cancer predictivity of the cytogenetic endpoints. We here report on the establishment of a joint data base comprising 5271 subjects, examined 1965-1988 for at least one cytogenetic biomarker. Totally, 3540 subjects had been examined for CA, 2702 for SCE and 1496 for MN. These cohorts have been followed-up with respect to subsequent cancer mortality or cancer incidence, and the expected values have been calculated from rates derived from the general populations in each country. Stratified cohort analyses will be performed with respect to the levels of the cytogenetic biomarkers. The importance of potential effect modifiers such as gender, age at test, and time since test, will be evaluated using Poisson regression models. The remaining two potential effect modifiers, occupational exposures and smoking, will be assessed in a case-referent study within the study base

    Full Text Available Abstract Background Knowledge about the quality and organisation of care to terminally ill cancer patients with a relatives' view in a primary health care setting is limited. The aim of the study is to analyse experiences and preferences of bereaved relatives to terminally ill cancer patients in a primary care setting to explore barriers and facilitators for delivery of good palliative home care. Methods Three focus group interviews with fourteen bereaved relatives in Aarhus County, Denmark. Results Three main categories of experience were identified: 1 The health professionals' management, where a need to optimize was found. 2 Shared care, which was lacking. 3 The relatives' role, which needs an extra focus. Conclusion Relatives experience insufficient palliative care mainly due to organizational and cultural problems among professionals. Palliative care in primary care in general needs improvement and attention should be drawn to the "professionalization" of the relatives and the need to strike a balance between their needs, wishes and resources in end-of-life care and bereavement.

    We evaluated the safety and efficacy of gefitinib treatment in elderly patients with non-small-cell lung cancer (NSCLC). We retrospectively compared toxicity, response and survival outcomes for gefitinib in patients aged 75 years or older (elderly group) with the same outcomes in patients aged younger than 75 years. In total, 350 patients were eligible for this analysis, of whom 92 were in the elderly group and 258 in the non-elderly group. In the elderly group, adverse events were generally mild to moderate and grade 3-4 adverse events were observed in 8 (9%) patients. The objective response rate (17 vs. 21% for elderly vs. non-elderly, respectively) and median survival time (7.6 vs. 9.3 months) were also similar in the two groups. Multivariate analysis revealed elderly patients with lower Brinkman index tended to be more sensitive to gefitinib (odds ratio: 4.57, 95% confidence interval: 0.91-22.72, p = 0.0642). In this study, treatment with gefitinib appeared to be as safe and effective in elderly patients (aged 75 or older) with NSCLC as in non-elderly patients.

    Internet Cancer Support Groups (ICSGs) are an emerging form of support group on Internet specifically for cancer patients. Previous studies have indicated the effectiveness of ICSGs as a research setting or a data-collection method. Yet recent studies have also indicated that ICSGs tend to serve highly educated, high-income White males who tend to be at an early stage of cancer. In this article, a total of 317 general ICSGs and 229 ethnic-specific ICSGs searched through Google.com, Yahoo.com, Msn.com, AOL.com, and ACOR.org are analyzed from a feminist perspective. The written records of group discussions and written memos by the research staff members were also analyzed using content analysis. The idea categories that emerged about these groups include (a) authenticity issues; (b) ethnicity and gender issues; (c) intersubjectivity issues; and (d) potential ethical issues. The findings suggest that (a) researchers adopt multiple recruitment strategies through various Internet sites and/or real settings; (b) researchers raise their own awareness of the potential influences of the health-related resources provided by ICSGs and regularly update their knowledge related to the federal and state standards and/or policies related to ICSGs; and (c) researchers consider adopting a quota-sampling method.

    Hepatocellular carcinoma (HCC) can be diagnosed based on characteristic findings of arterial-phase enhancement and portal/delayed 'washout' in cirrhotic patients. Several countries and major academic societies have proposed varying specific diagnostic criteria for HCC, largely reflecting the variable HCC prevalence in different regions and ethnic groups, as well as different practice patterns. In 2014, a new version of Korean practice guidelines for management of HCC was released by the Korean Liver Cancer Study Group (KLCSG) and the National Cancer Center (NCC). According to the KLCSG-NCC Korea practice guidelines, if the typical hallmark of HCC (i.e., hypervascularity in the arterial phase with washout in the portal or 3 min-delayed phases) is identified in a nodule ≥ 1 cm in diameter on either dynamic CT, dynamic MRI, or MRI using hepatocyte-specific contrast agent in high-risk groups, a diagnosis of HCC is established. In addition, the KLCSG-NCC Korea practice guidelines provide criteria to diagnose HCC for subcentimeter hepatic nodules according to imaging findings and tumor marker, which has not been addressed in other guidelines such as Association for the Study of Liver Diseases and European Association for the Study of the Liver. In this review, we briefly review the new HCC diagnostic criteria endorsed by the 2014 KLCSG-NCC Korea practice guidelines, in comparison with other recent guidelines; we furthermore address several remaining issues in noninvasive diagnosis of HCC, including prerequisite of sonographic demonstration of nodules, discrepancy between transitional phase and delayed phase, and implementation of ancillary features for HCC diagnosis.

    In spite the close association of the triple-negative breast cancer immunophenotype with hereditary breast cancers and the BRCA1 pathway, there is a lack of population studies that determine the frequency of BRCA1 mutations among triple-negative breast cancer patients. To address this, we have screened a large sample of 403 women diagnosed with triple-negative invasive breast cancer, independently of their age or family history, for germline BRCA1 mutations. Median age at diagnosis was 50 years (range 20-83). The overall prevalence of triple-negative cases among the initial patient group with invasive breast cancer was 8%. BRCA1 was screened by direct DNA sequencing in all patients, including all exons where a mutation was previously found in the Greek population (exons 5, 11, 12, 16, 20, 21, 22, 23, 24-77% of the BRCA1 coding region), including diagnostic PCRs to detect the three Greek founder large genomic rearrangements. Sixty-five deleterious BRCA1 mutations were identified among the 403 triple-negative breast cancer patients (16%). Median age of onset for mutation carriers was 39 years. Among a total of 106 women with early-onset triple-negative breast cancer (<40 years), 38 (36%) had a BRCA1 mutation, while 27% of women with triple-negative breast cancer diagnosed before 50 years (56/208) had a BRCA1 mutation. A mutation was found in 48% (50/105) of the triple-negative breast cancer patients with family history of breast or ovarian cancer. It is noteworthy, however, that of the 65 carriers, 15 (23%) had no reported family history of related cancers. All but one of the carriers had grade III tumors (98%). These results indicate that women with early-onset triple-negative breast cancer, and ideally all triple-negative breast cancer patients, are candidates for BRCA1 genetic testing even in the absence of a family history of breast or ovarian cancer.

    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

    Investigator-initiated clinical trials are essential for improving the standard of care for cancer patients, because pharmaceutical companies do not conduct trials that evaluate combination chemotherapy using drugs from different companies, surgery, radiotherapy or multimodal treatments. Government-sponsored cooperative groups have played a vital role in developing cancer therapeutics since the 1950s in the USA; however, the establishment of these groups in Japan did not take place until 30 years later. Methodological standards for multicenter cancer clinical trials were established in the 1980s by the National Cancer Institute and cooperative groups. The Japan Clinical Oncology Group, one of the largest cooperative groups in the country, was instituted in 1990. Its data center and operations office, formed during the 1990s, applied the standard methods of US cooperative groups. At present, the Japan Clinical Oncology Group consists of 14 subgroups, a Data Center, an Operations Office, nine standing committees and an Executive Committee represented by the Japan Clinical Oncology Group Chair. Quality control and quality assurance at the Japan Clinical Oncology Group, including regular central monitoring, statistical methods, interim analyses, adverse event reporting and site visit audit, have complied with international standards. Other cooperative groups have also been established in Japan since the 1980s; however, nobody figures out all of them. A project involving the restructuring of US cooperative groups has been ongoing since 2005. Learning from the success of this project will permit further progress of the cancer clinical trials enterprise in Japan.

  4. The role of prophylactic cranial irradiation in regionally advanced non-small cell lung cancer. A Southwest Oncology Group Study

    Lung cancer is the most common malignant disease in the United States. Only the few tumors detected very early are curable, but there has been some progress in the management of more advanced non-small cell lung cancer, particularly in regionally inoperable disease. Prevention of central nervous system relapse is an important issue in this group of patients because brain metastases ultimately develop in 20% to 25% of them. Seventy-three patients with regionally advanced non-small cell lung cancer were entered into a Phase II trial of neutron chest radiotherapy sandwiched between four cycles of chemotherapy including cisplatin, vinblastine, and mitomycin C. Prophylactic cranial irradiation was administered concurrently with chest radiotherapy (3000 cGy in 10 fractions in 15 patients; 3600 cGy in 18 fractions in the remaining 50 patients). Patients underwent computed tomographic scan of the brain before treatment and every 3 months after treatment. The initial overall response rate was 79%, but 65 of the 73 patients have subsequently died of recurrent disease. Median follow-up is 9 months for all 73 patients and 26 months for eight long-term survivors. No patient who completed the prophylactic cranial irradiation program had clinical or radiologic brain metastases. Toxic reactions to prophylactic cranial irradiation included reversible alopecia in all patients, progressive dementia in one patient, and possible optic neuritis in one patient. Both of these patients received 300 cGy per fraction of irradiation. The use of prophylactic cranial irradiation has been controversial, but its safety and efficacy in this trial supports its application in a group of patients at high risk for central nervous system relapse. Further evaluation of prophylactic cranial irradiation in clinical trials for regionally advanced non-small cell lung cancer is warranted.

    Promoting safety in the workplace has been attempted in a variety of ways. Increasingly, industries are using groups such as safety teams and quality circles to promote worker safety. Group influences on individual behavior and attitudes have long been studied in the social psychology literature, but the theories have not been commonly found outside the psychology arena. This paper describes the group theories of group polarization, risky shift, social loafing, groupthink and team think and attempts to apply these theories to existing studies that examine work group influences on safety. Interesting parallels were found but only one study examined group influences as their primary focus of research. Since groups are increasingly used for safety promotion, future research on safety that studies group influences with respect to current group theories is recommended.

    Invasive fungal diseases (IFDs) have become major causes of morbidity and mortality among highly immunocompromised patients. Authoritative consensus criteria to diagnose IFD have been useful in establishing eligibility criteria for antifungal trials. There is an important need for generation of consensus definitions of outcomes of IFD that will form a standard for evaluating treatment success and failure in clinical trials. Therefore, an expert international panel consisting of the Mycoses Study Group and the European Organization for Research and Treatment of Cancer was convened to propose guidelines for assessing treatment responses in clinical trials of IFDs and for defining study outcomes. Major fungal diseases that are discussed include invasive disease due to Candida species, Aspergillus species and other molds, Cryptococcus neoformans, Histoplasma capsulatum, and Coccidioides immitis. We also discuss potential pitfalls in assessing outcome, such as conflicting clinical, radiological, and/or mycological data and gaps in knowledge.

    Full Text Available Abstract Background Data from the California Health Interview Survey (CHIS indicate that levels and temporal trends in colorectal cancer (CRC screening prevalence vary among Asian American groups; however, the reasons for these differences have not been fully investigated. Methods Using CHIS 2001, 2003 and 2005 data, we conducted hierarchical regression analyses progressively controlling for demographic characteristics, English proficiency and access to care in an attempt to identify factors explaining differences in screening prevalence and trends among Chinese, Filipino, Vietnamese, Korean and Japanese Americans (N = 4,188. Results After controlling for differences in gender and age, all Asian subgroups had significantly lower odds of having ever received screening in 2001 than the reference group of Japanese Americans. In addition, Korean Americans were the only subgroup that had a statistically significant decline in screening prevalence from 2001 to 2005 compared to the trend among Japanese Americans. After controlling for differences in education, marital status, employment status and federal poverty level, Korean Americans were the only group that had significantly lower screening prevalence than Japanese Americans in 2001, and their trend to 2005 remained significantly depressed. After controlling for differences in English proficiency and access to care, screening prevalences in 2001 were no longer significantly different among the Asian subgroups, but the trend among Korean Americans from 2001 to 2005 remained significantly depressed. Korean and Vietnamese Americans were less likely than other groups to report a recent doctor recommendation for screening and more likely to cite a lack of health problems as a reason for not obtaining screening. Conclusions Differences in CRC screening trends among Asian ethnic groups are not entirely explained by differences in demographic characteristics, English proficiency and access to care. A

    The colour of the edible portion of vegetables and fruit reflects the presence of specific micronutrients and phytochemicals. No existing studies have examined the relationship between the intake of vegetable and fruit colour groups and the risk of colorectal cancer. The present study, therefore, aimed to investigate these associations in a Chinese population. A case-control study was conducted between July 2010 and July 2014 in Guangzhou, China, in which 1057 consecutively recruited cases of colorectal cancer were frequency-matched to 1057 controls by age (5-year interval), sex and residence (rural/urban). A validated FFQ was used to collect dietary information during face-to-face interviews. Vegetables and fruit were classified into four groups according to the colour of their primarily edible parts: green; orange/yellow; red/purple; white. Unconditional logistic regression models were used to estimate the OR and 95 % CI. A higher consumption of orange/yellow, red/purple and white vegetables and fruit was inversely associated with the risk of colorectal cancer, with adjusted OR of 0·16 (95 % CI 0·12, 0·22) for orange/yellow, 0·23 (95 % CI 0·17, 0·31) for red/purple and 0·53 (95 % CI 0·40, 0·70) for white vegetables and fruit when the highest and lowest quartiles were compared. Total vegetable intake and total fruit intake have also been found to be inversely associated with colorectal cancer risk. However, the intake of green vegetable and fruit was not associated with colorectal cancer risk. The results of the present study, therefore, suggest that a greater intake of orange/yellow, red/purple and white vegetables and fruit is inversely associated with the risk of colorectal cancer.

  20. Group sequential monitoring based on the weighted log-rank test statistic with the Fleming-Harrington class of weights in cancer vaccine studies.

    2016-09-01

    In recent years, immunological science has evolved, and cancer vaccines are now approved and available for treating existing cancers. Because cancer vaccines require time to elicit an immune response, a delayed treatment effect is expected and is actually observed in drug approval studies. Accordingly, we propose the evaluation of survival endpoints by weighted log-rank tests with the Fleming-Harrington class of weights. We consider group sequential monitoring, which allows early efficacy stopping, and determine a semiparametric information fraction for the Fleming-Harrington family of weights, which is necessary for the error spending function. Moreover, we give a flexible survival model in cancer vaccine studies that considers not only the delayed treatment effect but also the long-term survivors. In a Monte Carlo simulation study, we illustrate that when the primary analysis is a weighted log-rank test emphasizing the late differences, the proposed information fraction can be a useful alternative to the surrogate information fraction, which is proportional to the number of events.

    1989-01-01

    The present collaborative study was performed in four confined, neighboring regions of Austria, Hungary, Yugoslavia and Czechoslovakia with different demographic and occupational characteristics of their respective populations, various structures of medical facilities, and cancer registration systems. Crude and age-standardized incidence rates and trends of six major cancer sites (stomach, colorectum and lung in both sexes as well as breast, uterine cervix and uterine body in women) in three 4-year periods (1969-1972, 1973-1976, 1977-1980) were computed and mutually compared in the mentioned regions. Relatively high, different but more or less decreasing incidence rates of stomach, and varying but mainly increasing rates and trends of colorectal cancer were observed, while lung cancer incidence rates and tendencies showed great variations in both sexes. For women, besides continuous increase, the tendencies towards culmination and stabilization were found in regions with the highest incidence rates of breast and uterine body cancer in comparison with the more or less declining rates of uterine cervix cancer over the period studied. The observed different incidence rates and trends of these and obviously of other cancer sites require further investigations using more sophisticated epidemiological methods and approaches.

    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

    BACKGROUND In the current American Joint Committee on Cancer/International Union Against Cancer staging system (seventh edition) for intrahepatic cholangiocarcinoma (ICC), tumor size was excluded, and periductal invasion was added as a new tumor classification‐defining factor. The objective of the current report was to propose a new staging system for ICC that would be better for stratifying the survival of patients based on data from the nationwide Liver Cancer Study Group of Japan database. METHODS Of 756 patients who underwent surgical resection for ICC between 2000 and 2005, multivariate analyses of the clinicopathologic factors of 419 patients who had complete data sets were performed to elucidate relevant factors for inclusion in a new tumor classification and staging system. RESULTS Overall survival data were best stratified using a cutoff value of 2 cm using a minimal P value approach to discriminate patient survival. The 5‐year survival rate of 15 patients who had ICC measuring ≤2 cm in greatest dimension without lymph node metastasis or vascular invasion was 100%, and this cohort was defined as T1. Multivariate analysis of prognostic factors for 267 patients with lymph node‐negative and metastasis‐negative (N0M0) disease indicated that the number of tumors, the presence arterial invasion, and the presence major biliary invasion were independent and significant prognostic factors. The proposed new system, which included tumor number, tumor size, arterial invasion, and major biliary invasion for tumor classification, provided good stratification of overall patient survival according to disease stage. Macroscopic periductal invasion was associated with major biliary invasion and an inferior prognosis. CONCLUSIONS The proposed new staging system, which includes a tumor cutoff size of 2 cm and major biliary invasion, may be useful for assigning patients to surgery.

    2006-08-01

    We examined coded emotional expression during an initial therapy session and its association with a known physiological risk factor for early death, aberrant diurnal cortisol slope, in women with metastatic breast cancer. Out of 64 women with metastatic breast cancer randomized to a multi-site clinical intervention trial of supportive-expressive group therapy (SET), a subsample of 29 met eligibility criteria for this study. We tested whether longer mean durations of primary negative affect (fear, sadness, and anger) expression were associated with steeper diurnal cortisol slopes after adjusting for speaking time, repressive-defensiveness, anxiety, and the interaction between repressive-defensiveness and anxiety. We found that steeper cortisol slopes were related to lower repressive-defensiveness and greater primary negative affect expression in line with a priori hypotheses. Additionally we explored whether coded positive affect, defensive/hostile affect, constrained anger, and the interaction between primary negative affect and repressive-defensiveness explained additional variance in diurnal cortisol patterns.

    Hepatic resection (HX), percutaneous ethanol injection (PEI), and transcatheter arterial embolization (TCAE) have all been used in the treatment of patients with small-sized hepatocellular carcinomas (HCCs). However, the indications for these therapeutic modalities remain unclear. Therefore, the first step to minimize the debate on these indications is to review the standard results from each treatment based on an extensive survey. The participants in this study were patients with HCCs less than 5 cm in diameter who were enrolled in The Liver Cancer Study Group of Japan. The survival rates in the HX (n = 8,010), PEI (n = 4,037), and TCAE (n = 841) groups were calculated in relation to the number of tumors and the clinical stage. In the clinical stage I cases with a solitary tumor less than 2 cm in diameter and in all clinical stages with a solitary tumor greater than 2 cm and in the clinical stage II cases with 2 tumors greater than 2 cm, the HX group showed higher survival rates than the nonsurgical groups. The HX group had a higher male/female ratio and a younger mean age than the PEI or TCAE group. The ratio of HBs antigen-positive cases/hepatitis C virus antibody-positive cases in the PEI group was lower than that in the corresponding HX group. In contrast, the PIVKA-II values in the HX group tended to be higher than in the PEI group. In conclusion, these findings will provide useful information for selection of a therapeutic modality for small-sized HCCs.

    Full Text Available In this study, a series of regioisomeric acetylenic sulfamoylquinolines are designed, synthesized, and tested in vitro for their antiproliferative activity against three human breast cacer cell lines (T47D, MCF-7, and MDA-MB-231 and a human normal fibroblast (HFF-1 by 4-[3-(4-iodophenyl-2-(4-nitrophenyl-2H-5-tetrazolio]-1,3-benzene disulfonate (WST-1 assay. The antiproliferative activity of the tested acetylenic quinolinesulfonamides is comparable to that of cisplatin. The bioassay results demonstrate that most of the tested compounds show potent antitumor activities, and that some compounds exhibit better effects than the positive control cisplatin against various cancer cell lines. Among these compounds, 4-(3-propynylthio-7-[N-methyl-N-(3-propynylsulfamoyl]quinoline shows significant antiprolierative activity against T47D cells with IC50 values of 0.07 µM. In addition, 2-(3-Propynylthio-6-[N-methyl-N-(3-propynylsulfa-moyl]quinoline and 2-(3-propynylseleno-6-[N-methyl-N-(3-propynylsulfamoyl]quinoline display highly effective atitumor activity against MDA-MB-231 cells, with IC50 values of 0.09 and 0.50 µM, respectively. Furthermore, most of the tested compounds show a weak cytotoxic effect against the normal HFF-1 cell line. Additionally, in order to suggest a mechanism of action for their activity, all compounds are docked into the binding site of two human cytochrome P450 (CYP isoenzymes. These data indicate that some of the title compounds display significant cytotoxic activity, possibly targeting the CYPs pathways.

    Chromosomal aberrations (CAs), sister chromatid exchanges (SCEs), and micronuclei (MN) in peripheral blood lymphocytes have for decades been used as cytogenetic biomarkers to survey genotoxic risks in the work environment. The conceptual basis for this application has been the idea that increased...... cytogenetic damage reflects an enhanced cancer risk. Nordic and Italian cohorts have been established to evaluate this hypothesis, and analyses presented previously have shown a positive trend between CA frequency and increased cancer risk. We now report on a pooled analysis of updated data for 3541 subjects...... examined for CAs, 2703 for SCEs, and 1496 for MN. To standardize for interlaboratory variation, the results for the various cytogenetic end points were trichotomized on the basis of the absolute value distribution within each laboratory as "low" (1-33 percentile), "medium" (34-66 percentile), or "high" (67...

Four BC risk categories included BRCA1/2 carriers, increased, intermediate, and slightly increased risk. Women who developed BC from January 1, 1994, through December 31, 2005 (N = 44 were compared with the number of expected cases matched for age and period. BRCA1/2 carriers were identified by mutational analysis. Other risk groups were defined by different levels of family history for breast or ovarian cancer (OC. The standardized incidence ratio (SIR was used to evaluate the observed and expected ratio among groups. All statistical tests were two-sided. Results After a median follow-up of 55 months, there was a statistically significant difference between observed and expected incidence [SIR = 4.9; 95% confidence interval (CI = 1.6 to 7.6; p P P P = 0.0018 was higher than expected, while the difference between observed and expected among women at slightly increased risk was not statistically significant (SIR = 2.4, 95% CI = 0.9 to 8.3; P = .74. Conclusion The rate of cancers detected in women at high risk according to BRCA status or strong family history, as defined according to our operational criteria, was significantly higher than expected in an age-matched general population. However, we failed to identify a greater incidence of BC in the slightly increased risk group. These results support the effectiveness of the proposed program to identify and monitor individuals at high risk, whereas prospective trials are needed for

    Background Breast cancer (BC) detection in women with a genetic susceptibility or strong family history is considered mandatory compared with BC screening in the general population. However, screening modalities depend on the level of risk. Here we present an update of our screening programs based on risk classification. Methods We defined different risk categories and surveillance strategies to identify early BC in 1325 healthy women recruited by the Modena Study Group for familial breast and ovarian cancer.

    BACKGROUND: The frequency of postoperative infectious complications is significantly increased in patients with colorectal cancer receiving perioperative blood transfusion. It is still debated, however, whether perioperative blood transfusion alters the incidence of disease recurrence or otherwise...... affects the prognosis. METHODS: Patient risk variables, variables related to operation technique, blood transfusion and the development of infectious complications were recorded prospectively in 740 patients undergoing elective resection for primary colorectal cancer. Endpoints were overall survival (n.......13-2.82)), localization of cancer in the rectum and Dukes classification were independent risk factors. CONCLUSION: Blood transfusion per se may not be a risk factor for poor prognosis after colorectal cancer surgery. However, the combination of perioperative blood transfusion and subsequent development of postoperative...

    Controversies regarding the benefits of breast cancer screening programs have led to the promotion of new strategies taking into account individual preferences, such as decision aid. The aim of this study was to assess the impact of a decision aid leaflet on the participation of women invited to participate in a national breast cancer screening program. This Randomized, multicentre, controlled trial. Women aged 50 to 74 years, were randomly assigned to receive either a decision aid or the usual invitation letter. Primary outcome was the participation rate 12 months after the invitation. 16 000 women were randomized and 15 844 included in the modified intention-to-treat analysis. The participation rate in the intervention group was 40.25% (3174/7885 women) compared with 42.13% (3353/7959) in the control group (p = 0.02). Previous attendance for screening (RR = 6.24; [95%IC: 5.75-6.77]; p aid reduced the participation rate. The decision aid activate the decision making process of women toward non-attendance to screening. These results show the importance of promoting informed patient choices, especially when those choices cannot be anticipated.

    The aim of this study was to evaluate the efficacy of bioimpedance spectroscopy for the follow-up of patients with lymphedema in Turkey and its benefits in the diagnosis of stage 0, 1, and 2 lymphedema in patients who are under treatment for breast cancer. Thirty-seven female patients with breast cancer who underwent surgical procedures in our Breast Health Centre were followed up for lymphedema using bioimpedance, and clinical measurements were taken for a minimum period of 1 year at 3-month intervals. Patients who had been monitored regularly between November, 2011, and September, 2013, were enrolled to the study. In total, 8 patients developed lymphedema with an overall rate of 21.6%. Among the 8 patients who developed lymphedema, 4 had Stage 2, 1 had Stage 1, and 3 had Stage 0 lymphedema. Stage 0 lymphedema could not be detected with clinical measurements. During the patients' 1-year follow-up period using measurements of bioimpedance, a statistically significant relationship was observed between the occurrence of lymphedema and the disease characteristics. including the number of the extracted and remaining lymph nodes and the region of radiotherapy (p=0.042, p=0.024, p=0.040). Bioimpedance analysis seems to be a practical and reliable method for the early diagnosis of lymphedema. It is believed that regular monitoring of patients in the high-risk group using bioimpedance analyses increases the ability to treat lymphedema.

    Despite considerable improvement in the management of colon cancer, there is a great deal of variation in the outcomes among European countries, and in particular among different hospital centers in Greece and Cyprus. Discrepancy in the approach strategies and lack of adherence to guidelines for the management of colon cancer may explain the situation. The aim was to elaborate a consensus on the multidisciplinary management of colon cancer, based on European guidelines (ESMO and EURECCA), and also taking into account local special characteristics of our healthcare system. Following discussion and online communication among members of an executive team, a consensus was developed. Statements entered the Delphi voting system on two rounds to achieve consensus by multidisciplinary international experts. Statements with an agreement rate of ≥80% achieved a large consensus, while those with an agreement rate of 60-80% a moderate consensus. Statements achieving an agreement of Guidelines are proposed along with algorithms of diagnosis and treatment. The importance of centralization, care by a multidisciplinary team, and adherence to guidelines is emphasized.

    Full Text Available The PI3K-AKT pathway is frequently activated in breast cancer. PIK3CA mutations are most frequently found in the helical (exon 9 and kinase (exon 20 domains of this protein. The aim of the present study was to examine the role of different types of PIK3CA mutations in combination with molecular biomarkers related to PI3K-AKT signaling in patients with early breast cancer.Tumor tissue samples from 1008 early breast cancer patients treated with adjuvant chemotherapy in two similar randomized trials of HeCOG were examined. Tumors were subtyped with immunohistochemistry (IHC and FISH for ER, PgR, Ki67, HER2 and androgen receptor (AR. PIK3CA mutations were analyzed by Sanger sequencing (exon 20 and qPCR (exon 9 (Sanger/qPCR mutations. In 610 cases, next generation sequencing (NGS PIK3CA mutation data were also available. PIK3CA mutations and PTEN protein expression (IHC were analyzed in luminal tumors (ER and/or PgR positive, molecular apocrine carcinomas (MAC; ER/PgR negative / AR positive and hormone receptor (ER/PgR/AR negative tumors.PIK3CA mutations were detected in 235/1008 tumors (23% with Sanger/qPCR and in 149/610 tumors (24% with NGS. Concordance between the two methods was good with a Kappa coefficient of 0.76 (95% CI 0.69-0.82. Lobular histology, low tumor grade and luminal A tumors were associated with helical domain mutations (PIK3CAhel, while luminal B with kinase domain mutations (PIK3CAkin. The overall incidence of PIK3CA mutations was higher in luminal as compared to MAC and hormone receptor negative tumors (p = 0.004. Disease-free and overall survival did not significantly differ with respect to PIK3CA mutation presence and type. However, a statistically significant interaction between PIK3CA mutation status and PTEN low protein expression with regard to prognosis was identified.The present study did not show any prognostic significance of specific PIK3CA mutations in a large group of predominantly lymph-node positive breast cancer

    As reported in previous investigations, erythrocytes are the elements of peripheral blood most affected by free radical activity in the pathogenesis of cancer. In these studies, the level of sulphydrilic groups and reduced glutathione were assayed in the erythrocytes and plasma, while their successful scavenger activity against cell membrane oxidation and peroxidation has already been established. In subjects with cancer, the levels of -SH groups (p < 0.002) and reduced glutathione in both plasma and erythrocytes (p < 0.0001) were shown be a statistically significantly decreased compared to healthy controls. These differences were related to the defence of the hematic tissue against free radical activity. A similar pattern has also been reported when studying vitamin A and E content in the peripheral blood of cancer patients. The role of oxido-reduction phenomena in this disease is discussed, as well as the importance of reducing the oxido-peroxidation involvement of tissues and cell elements. The study of the GSH/GSSG ratio in order to determine the stage of the disease would be useful and might represent a systemic marker for cancerous lesions.

    Cytogenetic assays in peripheral blood lymphocytes (PBL) have been used extensively to survey the exposure of humans to genotoxic agents. The conceptual basis for this has been the hypothesis that the extent of genetic damage in PBL reflects critical events for carcinogenic processes in target...... tissues. Until now, no follow-up studies have been performed to assess the predictive value of these methods for subsequent cancer risk. In an ongoing Nordic cohort study of cancer incidence, 3182 subjects were examined between 1970 and 1988 for chromosomal aberrations (CA), sister chromatid exchange.......0009) in CA strata with regard to subsequent cancer risk. The point estimates of the standardized incidence ratio in the three CA strata were 0.9, 0.7, and 2.1, respectively. Thus, an increased level of chromosome breakage appears to be a relevant biomarker of future cancer risk....

    Steroid-induced osteonecrosis (ON) is a challenging complication encountered during modern chemotherapy for childhood acute lymphoblastic leukemia (ALL). We retrospectively assessed the incidence of ON and its risk factors in a total of 1095 patients enrolled in 3 consecutive Japanese Children's Cancer and Leukemia Study Group ALL studies (ALL941 [1994 to 2000], n=464; ALL2000 [2000 to 2004], n=305; and ALL2004 [2004 to 2010], n=326). ON was diagnosed in 16 patients, of whom 15 were symptomatic. The cumulative incidence of ON was 0.76% in ALL941, 0.35% in ALL2000, and 3.6% in ALL2004. The incidence of ON in ALL941/2000, in which only prednisolone was administered as a steroid, was significantly lower than that in ALL2004, in which dexamethasone was used as a partial substitute for prednisolone (P<0.01). In ALL2004, sex and age were significantly correlated with the incidence of ON (1.3% in boys vs. 6.7% in girls, P=0.0132; 0.42% for age <10 y vs. 15.6% for age ≥10 y, P<0.0001), suggesting that girls aged 10 years and above are at a greater risk of ON onset. These results indicate that the risk of ON should be considered when administering dexamethasone as part of ALL protocol treatment in girls aged 10 years and above.

    2011-06-01

    Recently, with advances in computer technologies, Internet cancer support groups became more popular than ever among people living with cancer. However, there is little information available on cancer patients' use of Internet cancer support groups, which may be partially due to a lack of instruments measuring cancer patients' use of Internet cancer support groups. Indeed, virtually no instrument measuring cancer patients' use of Internet cancer support groups can be identified through searches using multiple databases. In this study, a new instrument measuring the use of Internet cancer support groups was developed, and its psychometric properties were tested among 117 people living with cancer recruited through the Internet using a convenience sampling method. First, the development process of the new instrument, the Questions on the Use of Internet Cancer Support Groups, is described. Then, the pilot study on psychometric properties of the instrument is presented. Reliability was evaluated using internal consistency reliability testing, split-half reliability testing, and item analysis. Validity was assessed by using criterion validity, convergent validity, and face validity. The findings of the pilot study supported the reliability and validity of this new instrument. Based on the findings, some implications for future research are proposed.

    Increased fruit and vegetable consumption may protect against lung cancer, although epidemiologic findings are inconclusive. The authors prospectively examined associations between lung cancer risk and intakes of fruit, vegetables, and botanical subgroups in 472,081 participants aged 50-71 years in the National Institutes of Health (NIH)-AARP Diet and Health Study. Diet was assessed at baseline (1995-1996) with a 124-item dietary questionnaire. A total of 6,035 incident lung cancer cases were identified between 1995 and 2003. Total fruit and vegetable intake was unrelated to lung cancer risk in both men and women. Higher consumption of several botanical subgroups, however, was significantly inversely associated with risk, but only in men. For example, the relative risks of lung cancer among men in the highest versus lowest quintiles of intake of rosaceae, convolvulaceae, and umbelliferae were 0.82 (95% confidence interval (CI): 0.73, 0.91), 0.86 (95% CI: 0.75, 0.96), and 0.86 (95% CI: 0.78, 0.96), respectively; corresponding relative risks in women were 0.97 (95% CI: 0.85, 1.12), 0.95 (95% CI: 0.83, 1.09), and 0.92 (95% CI: 0.80, 1.06). These results provide support for a protective role of specific botanical subgroups of fruits and vegetables in lung cancer prevention in men, although the findings could also be due to residual confounding by smoking or chance.

    Sabarubicin (MEN-10755), a new synthetic anthracycline analogue, was evaluated for safety and efficacy in a multicentre phase II study in patients with advanced hormone refractory prostate cancer (HRPC). Thirty seven patients were included, of which 34 were evaluable for PSA response according to Bubley's criteria. Sabarubicin was administered as a short (30 min) intravenous infusion at a dose of 80 mg/m(2) every 3 weeks. The main toxicity consisted of grade 3/4 neutropenia in 24 patients (64.9%), with grade 3/4 febrile neutropenia occurring in one patient only. Grade 3/4 cardiotoxicity was observed in 4 patients including one ineligible. Other toxicities were mild. Nine patients achieved a PSA response (26.5%), 10 patients had stable disease (29.4%) and 14 patients disease progression (41.2%). One patient (2.9%) had a PSA response that was not confirmed by repeat PSA testing. The objective response rate according to RECIST criteria was 6.7% in 15 patients with measurable disease. The median duration of PSA responses was relatively long 7.1 months (95% CI 4.9-20.7) as was the median time to treatment progression in patients with stable disease. The median overall survival was 18.7 months (95% CI 9.1-N), comparable to results recently observed in taxotere-containing regimens. To confirm and extend these results, further testing of sabarubicin in larger trials is warranted.

    2008-03-15

    The purpose of this study was to clarify outcome for concurrent chemoradiation (CT-RT) in locally advanced cervix cancer in Japan. This is a non-randomized retrospective analysis of 226 patients treated with definitive CT-RT or radiotherapy alone (RT alone) in nine institutions between 2001 and 2003. External irradiation consisted of whole pelvic irradiation and pelvic side wall boost irradiation, using a central shield during the latter half of the treatment with the anteroposterior parallel opposing technique. The external beam irradiation was performed with 1.8 or 2 Gy per fraction. High-dose-rate intracavitary brachytherapy (HDR) was performed in all cases. In chemotherapy, platinum based drugs were used alone or in combination with other drugs such as 5FU. Grade of late complications was scaled retrospectively with CTCv2.0. Overall survival rate at 50 months of stage Ib, II and III, IV was 82% and 66% in CR-RT and 81% and 43% in R alone, respectively. Disease-free survival rate at 50 months of stage Ib, II and III, IV was 74% and 59% in CR-RT and 76% and 52% in R alone, respectively. There was no significant difference between CT-RT and RT for overall survival and disease free survival. Univariate analysis suggested that loco-regional control was better with CT-RT, but multivariate analysis could not confirm this finding. Compared to RT alone, CT-RT caused significantly more acute and late complications. Thus, late complication (grade 3-4) free survival rate at 50 month was 69% for CT-RT and 86% for RT alone (p<0.01). The therapeutic window with concomitant radiochemotherapy and HDR brachytherapy may be narrow, necessitating a close control of dose volume parameters and adherence to systems for dose prescription

Nineteen patients received gefitinib. EGFR expression was assessed by IHC, gene copy number by FISH, and mutation analysis was conducted for EGFR (18-21, KRAS, BRAF (V600E, and HER-2 exon 20. An additional TKI naive cohort of 73 patients was also screened. Results. Mutations were detected in 6/19 patients (3× EGFR, 1× KRAS, and 2× HER2-exon 20. There were no significant differences in TTP or OS for patients with somatic EGFR mutations. No BRAF mutations were detected. Conclusions. The incidence of EGFR mutations in H and N cancer in this study was 5.3%. No statistically relevant correlations between mutation or gene gain and response or survival were observed. Due to the limited number of patients and low incidence of genetic aberrations in the genes analyzed, additional studies are warranted.

    Full Text Available Abstract Background Platinum-based combinations are the standard second-line treatment for platinum-sensitive ovarian cancer (OC. This randomized phase II study was undertaken in order to compare the combination of carboplatin and pegylated liposomal doxorubicin (LD with carboplatin and paclitaxel (CP in this setting. Methods Patients with histologically confirmed recurrent OC, at the time of or more than 6 months after platinum-based chemotherapy, were randomized to six cycles of CP (carboplatin AUC5 + paclitaxel 175 mg/m2, d1q21 or CLD (carboplatin AUC5 + pegylated LD 45 mg/m2, d1q28. Results A total of 189 eligible patients (CP 96, CLD 93, with a median age of 63 years, median Performance Status (PS 0 and a median platinum free interval (PFI of 16.5 months, entered the study. Discontinuation due to toxicity was higher in the CP patients (13.5% versus 3%, P = 0.016. The overall response rate was similar: CP 58% versus CLD 51%, P = 0.309 (Complete Response; CR 34% versus 23% and there was no statistical difference in time-to-progression (TTP or overall survival (OS; TTP 10.8 months CP versus 11.8 CLD, P = 0.904; OS 29.4 months CP versus 24.7 CLD, P = 0.454. No toxic deaths were recorded. Neutropenia was the most commonly seen severe toxicity (CP 30% versus CLD 35%. More frequent in CLD were severe thrombocytopenia (11% versus 2%, P = 0.016, skin toxicity and Palmar-plantar erythrodysesthesia (PPE grade 1-2 (38% versus 9%, PP = 0.029, 20% versus 5%, P = 0.003. PS and PFI were independent prognostic factors for TTP and OS. Conclusions The combination of pegylated LD with carboplatin is effective, showing less neurotoxicity and alopecia than paclitaxel-carboplatin. It thus warrants a further phase III evaluation as an alternative treatment option for platinum-sensitive OC patients.

    Purpose: To investigate pelvic insufficiency fractures (IF) after definitive pelvic radiation therapy for early-stage uterine cervical cancer, by analyzing subjects of a prospective, multi-institutional study. Materials and Methods: Between September 2004 and July 2007, 59 eligible patients were analyzed. The median age was 73 years (range, 37-84 years). The International Federation of Gynecologic Oncology and Obstetrics stages were Ib1 in 35, IIa in 12, and IIb in 12 patients. Patients were treated with the constant method, which consisted of whole-pelvic external-beam radiation therapy of 50 Gy/25 fractions and high-dose-rate intracavitary brachytherapy of 24 Gy/4 fractions without chemotherapy. After radiation therapy the patients were evaluated by both pelvic CT and pelvic MRI at 3, 6, 12, 18, and 24 months. Diagnosis of IF was made when the patients had both CT and MRI findings, neither recurrent tumor lesions nor traumatic histories. The CT findings of IF were defined as fracture lines or sclerotic linear changes in the bones, and MRI findings of IF were defined as signal intensity changes in the bones, both on T1- and T2-weighted images. Results: The median follow-up was 24 months. The 2-year pelvic IF cumulative occurrence rate was 36.9% (21 patients). Using Common Terminology Criteria for Adverse Events version 3.0, grade 1, 2, and 3 IF were seen in 12 (21%), 6 (10%), and 3 patients (5%), respectively. Sixteen patients had multiple fractures, so IF were identified at 44 sites. The pelvic IF were frequently seen at the sacroileal joints (32 sites, 72%). Nine patients complained of pain. All patients' pains were palliated by rest or non-narcotic analgesic drugs. Higher age (>70 years) and low body weight (<50 kg) were thought to be risk factors for pelvic IF (P=.007 and P=.013, Cox hazard test). Conclusions: Cervical cancer patients with higher age and low body weight may be at some risk for the development of pelvic IF after pelvic radiation therapy.

    It has been suggested that tamoxifen may improve the efficacy of medical castration with luteinising hormone-releasing hormone analogues, but very few data have so far been published concerning the clinical and endocrinological activity of this therapeutic modality. In this phase II multicentre trial conducted by the Italian Trials in Medical Oncology group (ITMO), 64 premenopausal patients with hormone receptor-positive or unknown breast cancer were treated with monthly s.c. injections of goserelin 3.6 mg, in association with a tamoxifen daily dose of 20 mg, as first-line therapy for their advanced disease. All of the patients were evaluable for efficacy and there was an overall response rate of 41% (95% confidence interval 28-52%), with 7 of the 26 responders achieving complete remission. The median time to response was 4 months (range 2-17), and the median response duration was 13 months (range 6-37 +). Better responses were observed in soft tissues (51%); the response in visceral and bone metastases was respectively 19% and 37%. Serum concentrations of gonadotrophins and oestradiol were significantly decreased by the treatment, oestrogen levels being constantly suppressed to within the range observed in post-menopausal women. No significant change was detected in serum testosterone levels. In our experience, although it was not associated with any increased clinical efficacy, the concurrent use of goserelin and tamoxifen proved to be a feasible approach in the management of premenopausal advanced breast cancer.

    Purpose: A nomogram is a predictive statistical model that generates the continuous probability of a clinical event such as death or recurrence. The aim of the study was to construct a nomogram to predict 5-year overall survival after postoperative radiation therapy for stage IB to IIA cervical cancer. Methods and Materials: The clinical data from 1702 patients with early-stage cervical cancer, treated at 10 participating hospitals from 1990 to 2011, were reviewed to develop a prediction nomogram based on the Cox proportional hazards model. Demographic, clinical, and pathologic variables were included and analyzed to formulate the nomogram. The discrimination and calibration power of the model was measured using a concordance index (c-index) and calibration curve. Results: The median follow-up period for surviving patients was 75.6 months, and the 5-year overall survival probability was 87.1%. The final model was constructed using the following variables: age, number of positive pelvic lymph nodes, parametrial invasion, lymphovascular invasion, and the use of concurrent chemotherapy. The nomogram predicted the 5-year overall survival with a c-index of 0.69, which was superior to the predictive power of the International Federation of Gynecology and Obstetrics (FIGO) staging system (c-index of 0.54). Conclusions: A survival-predicting nomogram that offers an accurate level of prediction and discrimination was developed based on a large multi-center study. The model may be more useful than the FIGO staging system for counseling individual patients regarding prognosis.

  7. The implication and potential applications of high-mobility group box 1 protein in breast cancer.

    Sohun, Moonindranath; Shen, Huiling

    2016-06-01

    High-mobility group box 1 protein (HMGB1) is a highly conserved, non-histone and ubiquitous chromosomal protein found enriched in active chromatin forming part of the high mobility group family of proteins and is encoded by the HMGB1 gene (13q12) in human beings. It has various intranuclear and extracellular functions. It plays an important role in the pathogenesis of many diseases including cancer. In 2012, there was approximately 1.67 million new breast cancer cases diagnosed which makes it the second most frequent cancer in the world after lung cancer (25% of all cancers) and the commonest cancer among women. Both pre-clinical and clinical studies have suggested that HMGB1 might be a useful target in the management of breast cancer. This review summarises the structure and functions of HMGB1 and its dual role in carcinogenesis both as a pro-tumorigenic and anti-tumorigenic factor. It also sums up evidence from in vitro and in vivo studies using breast cancer cell lines and samples which demonstrate its influence in radiotherapy, chemotherapy and hormonal therapy in breast cancer. It may have particular importance in HER2 positive and metastatic breast cancer. It might pave the way for new breast cancer treatments through development of novel drugs, use of microRNAs (miRNAs), targeting breast cancer stem cells (CSCs) and breast cancer immunotherapy. It may also play a role in determining breast cancer prognosis. Thus HMGB1 may open up novel avenues in breast cancer management.

    Full Text Available Background: The TP53 gene is the most important tumor suppressor gene in humans. The aim of our study was to determine the genotype frequency of three common TP53 polymorphisms (codon 72 BstUI and intron 6 MspI, as well as the intron 3 in a group of Iranian women with and without breast cancer. Methods: Paraffin-embedded specimens of 65 malignant breast cancer cases and 65 cases with benign breast lesions were investigated for the presence of three common TP53 polymorphisms by polymerase chain reaction. Samples were genotyped by polymerase chain reaction followed by variant specific restriction enzyme digestion. Results: In our study, age grouping as >50 and ≤50 showed that the highest number of cancerous and non-cancerous patients was in the age group under 50; according to statistical tests, the difference was significant and recessive alleles of all three hot spots of TP53 had the highest frequency in the cancerous group. The majority of the cases with recessive alleles of all three hot spots of TP53 were in the age group ≤ 50. The difference between cancerous and noncancerous groups was statistically significant. Conclusions: Our results indicate that recessive alleles in three hot spots of TP53 gene might play a role in the breast cancer development, especially in women younger than 50 years.

    Importance A recent randomized radiation dose escalation trial in unresectable stage III NSCLC showed a lower survival in the high-dose arm (74Gy vs. 60Gy) with concurrent chemotherapy. Quality of life (QOL), an important secondary endpoint, is presented here. Objective The primary QOL hypothesis predicted a clinically meaningful decline (CMD) in QOL via the Functional Assessment of Cancer Therapy-Lung Cancer Subscale (FACT-LCS) in the high-dose RT-arm at 3 months. Design RTOG 0617 was a randomized phase III study (conducted from Nov 2007 to Nov 2011) in stage III NSCLC using a 2×2 factorial design and stratified by histology, PET staging, performance status and radiation technique (3D-conformal RT [3DCRT] vs. intensity-modulated radiation [IMRT]). Setting 185 institutions in the USA and Canada. Participants Of 424 eligible stage III NSCLC patients randomized, 360 (85%) consented to QOL, of whom 313 (88%) completed baseline QOL assessments. Intervention for Clinical Trials 74Gy vs. 60Gy with concurrent and consolidation carboplatin/paclitaxel +/− cetuximab. Main Outcomes and Measures QOL was collected prospectively via FACT-Trial Outcome Index (FACT-TOI), equaling Physical-Well-Being (PWB) + Functional-Well-Being (FWB) + Lung Cancer Subscale (LCS). Data are presented at baseline & 3 and 12 months via minimal clinically meaningful changes of >=2 points for PWB, FWB or LCS or >=5 points for TOI. Results Patient demographics and baseline QOL scores were comparable between the 74Gy and 60Gy arms. Two-hundred-nineteen (72%) of living patients who completed QOL at baseline did so at 3 months and 137 (57%) of living patients did so at 12 months. Significantly more patients on 74Gy arm had clinically meaningful decline in FACT-LCS at 3 months than on the 60Gy arm (45% vs. 30%, p=0.02). At 12 months, fewer patients who received IMRT (vs 3DCRT) had clinically meaningful decline in FACT-LCS (21% vs 46%, p=0.003). Baseline FACT-TOI was associated with overall survival in

    Vaginal dryness is a common problem for which effective and safe nonestrogenic treatments are needed. Based on preliminary promising data that pilocarpine attenuated vaginal dryness, the current trial was conducted. A double-blind, placebo-controlled, randomized trial design was used to compare pilocarpine, at target doses of 5 mg twice daily and 5 mg four times daily, with a placebo. Vaginal dryness was recorded by patient-completed questionnaires at baseline and weekly for 6 weeks after study initiation. The primary endpoint for this study was the area under the curve summary statistic composed of the longitudinal responses obtained at baseline and through the 6 weeks of treatment to a numerical analogue scale asking patients to rate their perceived amount of vaginal dryness. The primary analysis was carried out by a single t test using a two-side alternative to compare the collective pilocarpine treatment arms with the collective placebo arms. A total of 201 patients enrolled in this trial. The primary analysis, comparing vaginal dryness symptoms in the collective pilocarpine arms against the placebo arm, did not reveal any benefit for the pilocarpine treatment. This finding was confirmed by other secondary analyses. Toxicity evaluation revealed more nausea, sweating, rigors, and urinary frequency with the pilocarpine arms compared with the placebo arm.

    Camptothecins have shown efficacy in terms of response rate in patients with small cell lung cancer (SCLC). RFS2000 is a new camptothecin derivative, which has shown objective responses in various tumour types. The aim of this phase II study was to determine the objective response rate of RFS2000 in patients with sensitive and refractory SCLC. RFS2000 was given orally at 1.5 mg/m(2) per day for five consecutive days (five days on - two days off) on a continuous basis. Patients were evaluated weekly for toxicity and every six weeks for response. Thirty seven patients were included, 36 patients (14 with sensitive and 22 with refractory SCLC) were evaluable for toxicity, and 35 patients were evaluable for response. No objective responses were observed. Toxicity was acceptable, with myelosuppression, nausea/vomiting, and diarrhoea as the main toxicities. RFS2000 therefore has an acceptable toxicity profile but is not active as a single agent in SCLC.

    The study comprised 262 patients with previously untreated advanced carcinoma of the prostate. Patients were randomized either to undergo orchidectomy or to receive combined treatment with Zoladex, 3.6 mg every 4 weeks, plus flutamide, 250 mg t.i.d. At present the median follow-up is 39 months....... The objective response to therapy was better in the Zoladex plus flutamide group, but no differences in subjective response, time to disease progression, or survival have been demonstrated between the 2 groups. Adverse effects were more common in the Zoladex plus flutamide group. Thus, 'total androgen blockade......' with Zoladex plus flutamide was not clinically superior to orchidectomy in the treatment of patients with advanced prostatic cancer....

    Bevacizumab improves survival when added to chemotherapy in metastatic colorectal cancer (mCRC). We assessed the safety and efficacy of bevacizumab in mCRC patients ≥70 years old (YO) vs. those plus bevacizumab were included. The primary end point was safety; secondary objectives were progression-free survival (PFS) and overall survival (OS). Data was collected retrospectively. Three-hundred eight patients (92 ≥70 YO, 216 bevacizumab-related adverse effects; all were bevacizumab in patients ≥70 YO included hypertension (37.0 %), venous thromboembolism (6.5 %), wound-healing complications (5.4 %), bleeding (7.6 %), fistula (4.3 %), arterial thromboembolism (3.3 %), congestive heart failure (2.2 %), and proteinuria (grades 1-2 only, 14.1 %). Treatment was stopped due to adverse effects in 6.0 % of older patients. Older patients had significantly more ischemic heart disease and hypertension at baseline, and were treated less with FOLFOX and more with 5FU/LV monotherapy; nevertheless, OS and PFS were similar in younger and older patients. Compared to younger patients, in older patients, rates of proteinuria (all grades 1-2) were significantly higher (14.1 vs. 5.6 %, p=0.012) and rates of treatment-related hypertension (grades 3-5) were marginally higher (37 vs. 25.9 %, p=0.053); rates of other adverse events were similar in the two groups. In our patient population, bevacizumab was safe and effective in older as well as younger patients.

    Full Text Available Abstract Background The Internet can increase access to psychosocial care for breast cancer survivors through online support groups. This study will test a novel prosocial online group that emphasizes both opportunities for getting and giving help. Based on the helper therapy principle, it is hypothesized that the addition of structured helping opportunities and coaching on how to help others online will increase the psychological benefits of a standard online group. Methods/Design A two-armed randomized controlled trial with pretest and posttest. Non-metastatic breast cancer survivors with elevated psychological distress will be randomized to either a standard facilitated online group or to a prosocial facilitated online group, which combines online exchanges of support with structured helping opportunities (blogging, breast cancer outreach and coaching on how best to give support to others. Validated and reliable measures will be administered to women approximately one month before and after the interventions. Self-esteem, positive affect, and sense of belonging will be tested as potential mediators of the primary outcomes of depressive/anxious symptoms and sense of purpose in life. Discussion This study will test an innovative approach to maximizing the psychological benefits of cancer online support groups. The theory-based prosocial online support group intervention model is sustainable, because it can be implemented by private non-profit or other organizations, such as cancer centers, which mostly offer face-to-face support groups with limited patient reach.

    Advanced ovarian carcinoma in early progression (<6 months) (AOCEP) is considered resistant to most cytotoxic drugs. Gemcitabine (GE) and oxaliplatin (OXA) have shown single-agent activity in relapsed ovarian cancer. Their combination was tested in patients with AOCEP in phase II study. Fifty patients pre-treated with platinum-taxane received q3w administration of OXA (100 mg m(-2), d1) and GE (1000 mg m(-2), d1, d8, 100-min infusion). Patient characteristics were a : median age 64 years (range 46-79),and 1 (84%) or 2 (16%) earlier lines of treatment. Haematological toxicity included grade 3-4 neutropaenia (33%), anaemia (8%), and thrombocytopaenia (19%). Febrile neutropaenia occurred in 3%. Non-haematological toxicity included grade 2-3 nausea or vomiting (34%), grade 3 fatigue (25%),and grade 2 alopecia (24%). Eighteen (37%) patients experienced response. Median progression-free (PF) and overall survivals (OS) were 4.6 and 11.4 months, respectively. The OXA-GE combination has high activity and acceptable toxicity in AOCEP patients. A comparison of the doublet OXA-GE with single-agent treatment is warranted.

    Exposure to cosmic ionising radiation, in addition to other specific occupational risks, is of concern to aircrew members. Epidemiological studies provide an objective way to assess the health of this occupational group. We systematically reviewed the epidemiological literature on health of aircrew members since 1990, focusing on cancer as the endpoint of interest. Sixty-five relevant publications were identified and reviewed. Whereas overall cancer incidence and mortality was generally lower than in the comparison population, consistently elevated risks were reported for breast cancer incidence in female aircrew members and for melanoma in both male and female aircrew members. Brain cancer was increased in some studies among pilots. Occasionally trends of increasing cancer mortality or incidence with increasing estimated radiation dose were reported. Ionising radiation is considered to contribute little if at all to the elevated risks for cancers among aircrew, whereas excess ultraviolet radiation is a probable cause of the increased melanoma risk.

    Colorectal cancer (CRC) can be effectively prevented via screening colonoscopy, yet adherence rates remain low among Latinos. Interventions targeting individual and cultural barriers to screening are needed. We developed an educational brochure to target these barriers faced by a diverse Latino population. The objective was to evaluate the responses of the target population to the culturally and theoretically informed brochure through community member focus groups. Facilitators conducted six focus groups, stratified by gender, language, and prior colonoscopy experience. Topics included: brochure content and layout, cancer knowledge, and CRC screening determinants. Focus groups documented community members' responses to the brochure's overall message and its informational and visual components. Changes to wording, visual aids, and content were suggested to make the brochure culturally more acceptable. Results indicated relevance of the theoretically and culturally guided approach to the development of the brochure leading to refinement of its content and design.

    Oral maxillo-facial region cancer carries major importance in the tumour pathology of the organism being characterized by a high frequency as well as by the variety of the clinical anatomical and topographic forms through which it is presented. Over 60% of labial carcinoma begins as an asymptomatic ulceration, therefore patients do not pay due attention, considering it a "rebellious thrush" and they make a specialized medical appointment in an advanced stage of the tumor. In this study we pursued the frequency of the lip cancer pathology compared to the total CMF; the distribution the lip cancer by sex and age in patients who submitted to the specialized service; the originating environment of the patient with lip cancer; the anatomical location of the lip cancer; the frequency of relapses after treatment; the presence of adenopathy in the first consultation. The study was performed at the Clinic of Cranio-Maxillofacial Surgery, University of Medicine and Pharmacy "Victor Babes" Timişoara and pursued statistical aspects of the lip cancer incidence over a period of five years (2007-2012). Pre- and postoperative patients were monitored constantly, registering in individual sheets the evolution of the disease, monitoring the relapses after treatment and the presence of adenopathy in the first consultation. As shown in the statistics made in the last five years (2007-2012), from a total of 8135 cases with CMF pathology hospitalized in the Timisoara surgery clinic, 163 cases, or 2%, were cancer of the lip. Analyzing the gender distribution shows that males represent 81% of cases while the remaining 19% were found in women. From the study of age distribution, we found that the number of cases increases with age: 153 cases over 60 years old and 58 cases between 20 - 60 years. Personal statistics from the 212 cases of cancer of the lip reveal that 143 (67%) patients were from the rural areas and 69 (33%) from urban areas. Neoplastic pathology is constantly increasing both

    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 Endoscopy-assisted breast surgery (EABS performed through minimal axillary and/or periareolar incisions is a possible alternative to open surgery for certain patients with breast cancer. In this study, we report the early results of an EABS program in Taiwan.The medical records of patients who underwent EABS for breast cancer during the period May 2009 to December 2014 were collected from the Taiwan Endoscopic Breast Surgery Cooperative Group database. Data on clinicopathologic characteristics, type of surgery, method of breast reconstruction, complications and recurrence were analyzed to determine the effectiveness and oncologic safety of EABS in Taiwan.A total of 315 EABS procedures were performed in 292 patients with breast cancer, including 23 (7.8% patients with bilateral disease. The number of breast cancer patients who underwent EABS increased initially from 2009 to 2012 and then stabilized during the period 2012-2014. The most commonly performed EABS was endoscopy-assisted total mastectomy (EATM (85.4% followed by endoscopy-assisted partial mastectomy (EAPM (14.6%. Approximately 74% of the EATM procedures involved breast reconstruction, with the most common types of reconstruction being implant insertion and autologous pedicled TRAM flap surgery. During the six-year study period, there was an increasing trend in the performance of EABS for the management of breast cancer when total mastectomy was indicated. The positive surgical margin rate was 1.9%. Overall, the rate of complications associated with EABS was 15.2% and all were minor and wound-related. During a median follow-up of 26.8 (3.3-68.6 months, there were 3 (1% cases of local recurrence, 1 (0.3% case of distant metastasis and 1 (0.3% death.The preliminary results from the EABS program in Taiwan show that EABS is a safe procedure and results in acceptable cosmetic outcome. These findings could help to promote this under-used surgical technique in the field of breast cancer.

    As arduous psychological reactions and loss of control almost inevitably represent a challenge for women diagnosed and treated for breast cancer, a participatory intervention study was initiated that aimed to enhance empowerment in breast cancer self-help groups. Women newly diagnosed with breast cancer were invited to participate. The intervention encompassed three professionally led self-help groups running sequentially, each group for approximately 4 months. Each group of five to seven participants met weekly. Several empowerment strategies were initiated by two professional facilitators, aiming to promote empowerment processes and to manage stress. The participants experienced group participation as both empowering and as a valuable source of support, and although the group processes developed very differently, a strong sense of fellowship developed in all three groups. The discussion highlights the findings in relation to several theoretical perspectives including social capital, social cohesion, risky agreements, helper-therapy and power/empowerment. We conclude that empowerment strategies that are implemented in professionally led breast cancer self-help groups can contribute to participant empowerment and function as an important source of re-discovery and confirmation of the participants' strengths and abilities.

    Purpose: The Korean Radiation Oncology Group (KROG) 08-06 study protocol allowed radiation therapy (RT) technique to include or exclude breast cancer patients from receiving radiation therapy to the internal mammary lymph node (IMN). The purpose of this study was to assess dosimetric differences between the 2 groups and potential influence on clinical outcome by a dummy run procedure. Methods and Materials: All participating institutions were asked to produce RT plans without irradiation (Arm 1) and with irradiation to the IMN (Arm 2) for 1 breast-conservation treatment case (breast-conserving surgery [BCS]) and 1 mastectomy case (modified radical mastectomy [MRM]) whose computed tomography images were provided. We assessed interinstitutional variations in IMN delineation and evaluated the dose-volume histograms of the IMN and normal organs. A reference IMN was delineated by an expert panel group based on the study guidelines. Also, we analyzed the potential influence of actual dose variation observed in this study on patient survival. Results: Although physicians intended to exclude the IMN within the RT field, the data showed almost 59.0% of the prescribed dose was delivered to the IMN in Arm 1. However, the mean doses covering the IMN in Arm 1 and Arm 2 were significantly different for both cases (P<.001). Due to the probability of overdose in Arm 1, the estimated gain in 7-year disease-free survival rate would be reduced from 10% to 7.9% for BCS cases and 7.1% for MRM cases. The radiation doses to the ipsilateral lung, heart, and coronary artery were lower in Arm 1 than in Arm 2. Conclusions: Although this dummy run study indicated that a substantial dose was delivered to the IMN, even in the nonirradiation group, the dose differences between the 2 groups were statistically significant. However, this dosimetric profile should be studied further with actual patient samples and be taken into consideration when analyzing clinical outcomes according to IMN

    2017-01-01

    Full Text Available Purpose: Women with breast cancer have complex and unique gynecologic needs that are challenging to effectively and comprehensively meet in a traditional gynecology visit format. Group medical visits are an effective and well-received model of care in other disease settings and can provide comprehensive health education as an adjunct to one-on-one evaluation and treatment. There are limited data regarding the use of this type of health care delivery in providing gynecology-focused care to women affected by breast cancer. Methods: A group medical visit model was created for gynecology providers to see new breast cancer patient consults. From May 2012 to February 2014, 148 patients (3–6 per group participated in a 1-hour informational session followed by a 15- to 30-minute individual visit with a physician that included history, physical examination and evaluation. We surveyed 101 women who attended these visits to evaluate a group model for providing gynecologic care and educational support to women with breast cancer. Results: Of those who responded to the survey question, 100% agreed or somewhat agreed that their expectations for an initial intake visit were met during the group visit; 81% agreed or somewhat agreed that they felt a group visit was preferable to an individual introductory visit. More than 95% agreed or somewhat agreed that the information was understandable and their questions were answered during the visit. Only 5 respondents expressed dissatisfaction with the additional time commitment for this type of visit. Conclusions: The majority of women surveyed expressed satisfaction with their experience with a group visit format. The women who participated preferred this format compared to an individual intake appointment when establishing gynecology care after breast cancer diagnosis/treatment, regardless of age, menopausal status, cancer stage or hormone receptor status. While further studies are warranted to directly compare and

    This study assessed the effects of a psychological group intervention based on positive psychology in women with breast cancer. 175 women were randomly assigned either to an experimental group, receiving the 14-session intervention (n = 87), or to a wait list group (n = 88) that did not receive any type of intervention. For treatment, a group intervention was applied, based on improving psychological strengths and enhancing positive psychology-based styles of coping. Strength-related outcomes, self-esteem, well-being, and happiness were assessed before and after the intervention. The experimental group showed higher scores on all of the study variables after the intervention. Participants reported improved self-esteem, emotional intelligence-related abilities, resilience, and optimism, as well as positive affectivity, well-being, and happiness. The results show a beneficial effect of this psychological intervention based on positive psychology on female breast cancer patients' psychological health.

    The prognosis of stage III non-small cell lung cancer (NSCLC) can be improved by a combination of radiotherapy (RT) and chemotherapy (CT). In this study, the GOTHA group evaluated the feasibility, tolerance, tumour response, pattern of failure and effect on survival of a combination alternating accelerated hyperfractionated (AH) RT and CT in patients with tumour stage III NSCLC. Toxic effects were leucopenia, nausea and vomiting, mucositis, diarrhoea, alopecia and peripheral neuropathy. Alternating CT and AHRT, as used in this study, were well tolerated and allowed full dose delivery within less than 12 weeks. Initial response was not predictive of survival. The survival curve is encouraging and the 5 year survival is superior to the 5% generally observed with conventionally fractionated radiotherapy. (author).

    A discrepancy exists between the 7th edition guidelines of the American Joint Committee on Cancer (AJCC) and the 3rd edition Japanese treatment guidelines in terms of the classification of No. 12a lymph nodes as regional or distant lymph nodes in D2 lymphadenectomy for gastric cancer. The scope definition of No. 12a lymph nodes has yet to be fully elucidated. The present study aimed to assess the appropriateness of reclassifying No. 12a lymph node metastasis as distant metastasis according to the survival rate outcome, and to provide a clear and practical definition of the No. 12a group lymph nodes of gastric cancer. A retrospective analysis was performed on patients with gastric cancer who underwent standard or greater lymphadenectomy between January 2000 and December 2009 to find an association between No. 12a node metastasis and survival outcome. The present study first presented a clear and practical scope definition of the No. 12a group lymph nodes of gastric cancer, according to our clinical experiences and practices (Table I and Fig. 1). The survival outcome of patients with gastric cancer and No. 12a lymph node metastasis was poorer compared with that of patients with no No. 12a lymph node metastasis (P=0.0003). The results were similar in stage III patients with gastric cancer (Pcancer (P=0.1968). Cox regression analysis revealed that the AJCC stage was independently associated with an unfavorable cumulative survival rate. Logistic regression analysis revealed that tumor location, AJCC stage, intravascular cancer emboli and nerve invasion were associated with No. 12a lymph node metastasis. In conclusion, the data in the present study suggested that No. 12a lymph node metastasis is associated with distant metastasis, and therefore they concur with the 7th edition AJCC gastric cancer guidelines, which appear to be correct in terms of considering No. 12a lymph node metastasis as distant metastasis.

    Prostate cancer is the second most common cancer in men, with a significant increase in incidence and mortality in men over 50 years of age. Natural killer cells (NK) are part of the innate immune system recognizing class I HLA molecules on target cells through their membrane receptors, called killer cell immunoglobulin-like receptors (KIR). The aim of our study is to evaluate the association between the KIR genes and HLA alleles in patients with prostate cancer and healthy controls. Two hundred patients with prostate cancer and 185 healthy controls were typed for HLA class I and KIR genes by PCR-SSP. When both groups were compared, no significant differences were found for HLA-C group 1 and group 2, HLA-Bw4, HLA-A3 and A11. No difference was seen either in KIR frequency between patients with prostate cancer and controls. In conclusion, our data suggest no potential role for the KIR gene system in prostate cancer.

    Purpose: A phase 2 study was completed by the Korean Gynecologic Oncologic Group to evaluate the efficacy and toxicity of concurrent chemoradiation with weekly paclitaxel in patients with high-risk endometrial cancer. Methods and Materials: Pathologic requirements included endometrial endometrioid adenocarcinoma stages III and IV. Radiation therapy consisted of a total dose of 4500 to 5040 cGy in 5 fractions per week for 6 weeks. Paclitaxel 60 mg/m{sup 2} was administered once weekly for 5 weeks during radiation therapy. Results: Fifty-seven patients were enrolled between January 2006 and March 2008. The median follow-up time was 60.0 months (95% confidence interval [CI], 51.0-58.2). All grade 3/4 toxicities were hematologic and usually self-limited. There was no life-threatening toxicity. The cumulative incidence of intrapelvic recurrence sites was 1.9% (1/52), and the cumulative incidence of extrapelvic recurrence sites was 34.6% (18/52). The estimated 5-year disease-free and overall survival rates were 63.5% (95% CI, 50.4-76.5) and 82.7% (95% CI, 72.4-92.9), respectively. Conclusions: Concurrent chemoradiation with weekly paclitaxel is well tolerated and seems to be effective for high-risk endometrioid endometrial cancers. This approach appears reasonable to be tested for efficacy in a prospective, randomized controlled study.

    The main purpose of the present study was to understand the subjective experience of patients adjusting to cancer by focusing on how that experience might be affected by participating in a psychodramatic group intervention. In-depth interviews using an interpretative-phenomenological approach were conducted with eight cancer patients involved in a psychodrama group. Four key themes were identified: (1) outside and inside relationships; (2) identities: nurturing other selves; (3) a feelings' gym: performing the internal world; and (4) many ends: mourning death and dying. Participation in cancer group using a psychodramatic approach provided positive results. In detail, the group setting: (1) favoured relationships in which it was possible to freely express oneself and (2) empowered patients in their feelings of being able to give and receive help; the psychodramatic approach: (1) supported the physical mobilisation of sense of agency and (2) permitted to deal with the grieving process. Cancer healthcare pathways would benefit from psychotherapeutic programmes using a similar approach, since psychodrama by actively involving body seems to works on areas that are often underwhelmed by other approaches, such as (i.e., physical mobilisation, body engagement, grieving adjustment). Psychodrama supports patients to achieve insights into their own possibilities to actively participate in their own life situations despite having cancer and undergoing treatment for it.

    To overcome barriers that prevent women with breast cancer from attending support groups, innovative formats and modes of delivery both need to be considered. The present study was part of an interdisciplinary program of research in which researchers from counseling psychology, psycho-oncology, nursing, computer science, and fine arts have explored art making as an innovative format and telehealth as a mode of delivery. For this study, we conducted focus groups and interviews with 25 people with expertise about breast cancer, art, art therapy, and distance delivery of mental health services to generate guidelines for distance art-based psychosocial support services to women with breast cancer. A qualitative analysis of the focus group and interview data yielded guidelines for developers and facilitators of distance art groups for women with breast cancer pertaining to (a) emotional expression, (b) emotional support, (c) emotional safety, and (d) accommodating individual differences, plus special considerations for art therapy groups. Further research is needed pertaining to the use of computers, involvement of art therapists, and screening out vulnerable clients.

    There is limited research on the relationship between Health-related quality of life (HRQoL) and socioeconomic status (SES) among long-term cancer survivors. The goal of this study was to assess Global HRQoL among 102 adult cancer survivors attending support groups in San Diego County and to examine differences by SES and acculturation. Community-based participatory research methods were followed to recruit a purposive sample of English and Spanish-speaking adult cancer survivors attending cancer support groups. Self-report questionnaires assessing age, acculturation (i.e., language), SES (i.e., income and education), cancer history, and Global HRQoL measured by the FACT-G were administered. Multivariate regression examined the relationship between SES and acculturation with HRQoL, adjusting for covariates. Participants were 58.8 years on average (SD = 10.06) and varied in terms of SES. Most participants (91.5 %) were women, 51.7 % were non-Hispanic white, and 48.3 % were Hispanic/Latino. Global HRQoL scores in the study sample were lower compared to previously reported studies. After adjusting for covariates, SES and acculturation were not significantly related to HRQoL. Stage at diagnosis was significantly related to HRQoL measures in adjusted analyses. HRQoL did not vary by SES or acculturation. There is a need to increase access to linguistically and culturally appropriate cancer care and supportive care services. Future studies may find existing support group settings useful for targeting psychosocial issues for more advanced stage cancer survivors.

    The authors report a retrospective assessment of late xerostomia according to the RTOG (Radiation Therapy Oncology Group) classification of the European Organization for Research and Treatment of Cancer (EORTC) among patients treated by intensity-modulated conformational radiotherapy (IMRT) and suffering from upper aero-digestive tract carcinomas of different stages. Some of these patients have bee operated, and some have been treated by chemotherapy. It appears that the IMRT results in a reduction of late xerostomia, and even in an absence of salivary toxicity.

    Full Text Available The study goal was to investigate thyroid cancer morbidity in population groups affected by the Chernobyl catastrophe. The study period comprised 1994-2006 for clean-up workers and 1990-2006 for Chernobyl evacuees and residents of contaminated territories. A significant increase of thyroid cancer incidence was registered in all observed population groups. The most significant excess over the national level was identified in clean-up workers. This amounted to a factor of 5.9, while it was 5.5 for the evacuees and 1.7 for the residents. The highest thyroid cancer risk was observed in persons exposed to radioiodine in childhood and adolescence.

    The FDI has shown considerable interest in the oral cancer and has in recent years arranged three symposia on the subject. The incidence of oral cancer shows marked geographic differences mostly depending upon environmental factors. In the present paper the epidemiology of oral cancer is illustrated by the relative frequency to total number of cancers and incidence rates from a number of countries. Canada has the highest rate of cancer of the vermilion border, which is extremely rare among dark-skinned people. Even within one country differences may be found, a fact which is illustrated by findings from Czechoslovakia and India. In most of the studies dealing with the etiology of oral cancer tobacco usage in its various forms is shown to be the outstanding factor.

    Breast cancer is the main cause of cancer-related death among women, with a 0.5% increase in incidence per year. Natural killer cells (NK) are part of the innate immune system recognizing class I HLA molecules on target cells through their membrane receptors, called killer cell immunoglobulin-like receptors (KIR). The aim of our study was to evaluate the association between the KIR genes and HLA alleles in patients with breast cancer and healthy controls. Two hundred thirty patients with breast cancer and 272 healthy controls were typed for HLA class I and KIR genes by PCR-SSO. When both groups were compared, the presence of inhibitory KIR2DL2 receptors was significantly higher in breast cancer patients than in healthy controls. No significant differences were found for HLA-C2 and HLA-Bw4. However, a higher frequency of HLA-C1 in breast cancer patients was observed. These findings suggest a potential role for the KIR gene system in breast cancer. Further studies to confirm this observation are warranted.

    Purpose We evaluated the efficacy and toxicity of mammalian target rapamycin inhibitors in Korean patients with metastatic renal cell carcinoma (mRCC) with chronic renal insufficiency not requiring dialysis. Materials and Methods Korean patients with mRCC and chronic renal insufficiency not requiring dialysis treated with everolimus or temsirolimus between January 2008 and December 2014 were included. Patient characteristics, clinical outcomes, and toxicities were evaluated. Overall survival (OS) and progression-free survival (PFS) durations were evaluated according to the degree of renal impairment. Results Eighteen patients were considered eligible for the study (median age, 59 years). The median glomerular filtration rate was 51.5 mL/min/1.73 m2. The best response was partial response in six patients and stable disease in 11 patients. The median PFS and OS durations were 8 months (95% confidence interval [CI], 0 to 20.4) and 32 months (95% CI, 27.5 to 36.5), respectively. The most common non-hematologic and grade 3/4 adverse events included stomatitis, fatigue, flu-like symptoms, and anorexia as well as elevated creatinine level. Conclusion Mammalian target rapamycin inhibitors were efficacious and did not increase toxicity in Korean patients with mRCC and chronic renal insufficiency not requiring dialysis. PMID:26875195

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

  1. Selecting a comparison group for 5-year oral and pharyngeal cancer survivors: Two methods

    Full Text Available Abstract Background To assess potential long-term consequences of cancer treatment, studies that include comparison groups are needed. These comparison groups should be selected in a way that allows the subtle long-range effects of cancer therapy to be detected and distinguishes them from the effects of aging and other risk factors. The purpose of this investigation was to test two methods of recruiting a comparison group for 5-year oral and pharyngeal cancer survivors (peer-nominated and listed sample with emphasis on feasibility and the quality of the match. Methods Participants were drawn from a pool of 5-year survivors treated at a large Southeastern hospital. A peer-nominated sample was solicited from the survivors. A listed sample matched on sex, age, and zip code was purchased. Telephone interviews were conducted by a professional call center. Results The following represent our key findings: The quality of matching between survivors and listed sample was better than that between survivors and peer-nominated group in age and sex. The quality of matching between the two methods on other key variables did not differ except for education, with the peer method providing a better match for the survivors than the listed sample. The yield for the listed sample method was greater than for the peer-nominated method. The cost per completed interview was greater for the peer-nominated method than the listed sample. Conclusion This study not only documents the methodological challenges in selecting a comparison group for studies examining the late effects of cancer treatment among older individuals but also documents challenges in matching groups that potentially have disproportionate levels of comorbidities and at-risk health behaviors.

    The French Groupe des Investigateurs Nationaux pour l'Etude des Cancers Ovariens (GINECO) conducted a multicenter phase II study of carboplatin and paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) to evaluate the efficacy and side effects of this combination in pretreated advanced ovarian cancer. Patients with progressive ovarian carcinoma during or after platinum-based chemotherapy received paclitaxel 175 mg/m2 intravenously over 3 hours followed by intravenous carboplatin over 30 minutes every 4 weeks. The dose of carboplatin was calculated using a projected area under the concentration-time curve of 5 mg/mL x min. Of the 50 patients entered, 50 were evaluable for toxicity and 42 for response. There were eight complete and 10 partial responses, for an overall response rate of 43% (95% confidence interval, 28% to 56%). Overall response rates in platinum refractory patients and in those with early (> or = 3 and or = 12 months) relapse was 28%, 33%, and 71%, respectively. Median response duration, progression-free survival, and overall survivals were 8, 6, and 14 months, respectively. The most frequent and severe toxicity was myelosuppression. Grades 3 and 4 neutropenia occurred in 30% and 23% of cycles, and granulocyte colony-stimulating factor was administered in 6%. Only one case of neutropenic fever was observed. Grades 3 and 4 thrombocytopenia occurred in 3% and 1% of cycles, respectively. Alopecia and moderate nausea or vomiting were frequent. Transitory peripheral neuropathy was present in 45% of patients but was severe in only one patient. One early death was observed due to progressive disease and possibly to therapy. The combination of paclitaxel 175 mg/m2 as a 3-hour infusion and carboplatin dosed to an area under the concentration-time curve of 5 is an effective therapy in patients previously treated with platinum-based chemotherapy and may be administered safely to outpatients who relapse after one or two lines of chemotherapy.

    In studies of skin cancer, participants are often classified into risk groups based on self-reported history of sun exposure or skin characteristics. We sought to determine the reliability of self-reported skin characteristics among participants of a study to evaluate markers for nonmelanoma skin cancer (NMSC). Multiple questionnaires and screening protocols were administered over a 3-month period to individuals from three risk groups: existing sun damage on forearms but no visible actinic keratoses (n = 91), visible actinic keratoses (n = 38), and history of resected squamous cell skin cancer in the last 12 months (n = 35). We assessed consistency of risk group assignment between telephone screen and study dermatologist assignment, self-reported sun sensitivity (telephone recruitment form versus participant completed profile), and self-reported history of NMSC skin lesions (telephone recruitment form versus health history). There was substantial agreement between probable risk group and final assignment (kappa = 0.76; 95% confidence interval, 0.65-0.85) and agreement did not differ by gender. Agreement for self-reported sun sensitivity was moderate (kappa weighted = 0.46; 95% confidence interval, 0.36-0.56) with higher agreement for women. For self-reported NMSC lesion history between two interviews, 24 days apart, kappa estimates ranged from 0.66 to 0.78 and were higher for women than men. Overall, there was evidence for substantial reproducibility related to risk group assignment and self-reported history of NMSC, with self-reported sun sensitivity being less reliable. In all comparisons, women had higher kappa values than men. These results suggest that self-reported measures of skin cancer risk are reasonably reliable for use in screening subjects into studies.

    Gastric cancer (GC) remains a major killer throughout the world. Despite the dramatic decrease in GC over the last century, its etiology has not yet been well characterized. This study investigated the possible independent and combined effects of the dinner-to-bed time and post-dinner walk on the risk for GC across different age groups. A population-based, case-control study was conducted in southeast China, including 452 patients with GC and 465 age-, race-, and gender-matched controls. A self-designed questionnaire was used to collect information on demographic characteristics, dinner-to-bed time, post-dinner walk, and other behavioral factors. Conditional logistic regression models were used to estimate the effects of the dinner-to-bed time and post-dinner walk as well as their joint effect on the risk for GC across different age groups. Individuals with dinner-to-bed time time was, the higher was the risk for GC (Ptrend time and post-dinner walk on GC risk was detected (AOR = 1.862, 95% CIs = 1.584-3.885, synergy index [SI] = 2.654, 95% CIs = 2.27-3.912). Participants with dinner-to-bed time times likely to suffer from GC (AOR = 7.401, 95% CIs = 4.523-13.16) than those with dinner-to-bed time ≥4 hours who took such walk.

    Age has been included in various prognostic scoring systems for differentiated thyroid cancer (DTC). The aim of this study is to re-examine the relationship between age and prognosis by using Surveillance, Epidemiology, and End Results (SEER) population-based database. We identified 51,061 DTC patients between 2004 and 2012. Patients were separated into 10-year age groups. Cancer cause-specific survival (CSS) and overall survival (OS) data were obtained. Kaplan-Meier and multivariable Cox models were built to analyze the outcomes and risk factors. Increasing age gradient with a 10-year interval was associated with the trend of higher proportions for male gender, grade III/IV and summary stage of distant metastases. Both CSS and OS continued to worsen with increasing age, being poorest in in the oldest age group (≥71); multivariate analysis confirmed that CSS continued to fall with each age decade, significantly starting at 60 years (HR = 7.5, 95% 1.0–54.1, p = 0.047) compared to the young group (≤20). Similarly, multivariate analysis suggested that OS continued worsening with increasing age, but starting at 40 years (HR = 3.7, 95% 1.4–10.1, p = 0.009) compared to the young group. The current study suggests that an age exceeding 60 years itself represents an unfavorable prognostic factor and high risk for cancer-specific death in DTC. PMID:27272218

    Background Several studies have evaluated the association between polymorphisms of encoding excision repair cross complementation group 1 (ERCC1) enzyme and lung cancer risk in diverse populations but with conflicting results.By pooling the relatively small samples in each study, it is possible to perform a meta-analysis of the evidence by rigorous methods.Methods Embase, Ovid, Medline and Chinese National Knowledge Infrastructure were searched. Additional studies were identified from references in original studies or review articles. Articles meeting the inclusion criteria were reviewed systematically, and the reported data were aggregated using the statistical techniques of meta-analysis.Results We found 3810 cases with lung cancer and 4332 controls from seven eligible studies. T19007C polymorphism showed no significant effect on lung cancer risk (C allele vs. T allele: odds ratio (OR)=0.91, 95% confidence interval (CI)=0.80-1.04; CC vs. TT: OR=0.76, 95% CI=0.56-1.02; CC vs. (CT+TT): OR=0.96, 95% CI=-0.84-1.10). Similarly,there was no significant main effects for T19007C polymorphism on lung cancer risk when stratified analyses by ethnicity (Chinese or Caucasian). No significant association was found between C8092A polymorphism (3060 patients and 2729 controls) and the risk of lung cancer (A allele vs. C allele: OR=1.03, 95% CI=0.95-1.11; AA vs. CC: OR=1.08, 95% CI=-0.88-1.33; AA vs. (AC+CC): OR=1.08, 95% CI=-0.88-1.31).Conclusion We found little evidence of an association between the T1900C or C8092A polymorphisms of ERCC 1 and the risk of lung cancer in Caucasian or Han Chinese people.

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

    Cancer illness affects people in many ways, physical, financial, and existential. In this paper, we describe a proposed group intervention for individuals with advanced disease who want help finding a sense of meaning at this critical juncture in their lives. This intervention has a brief, semi-structured format, and is informed by the work of Viktor Frankl, empirical findings in the area of meaning and trauma, and the empirical findings of other group interventions for cancer patients. Individual sessions focus on different aspects of meaning, including responsibility to others, creativity, transcendence, and ascertaining one's values and priorities. Having goals on which to focus and feeling like part of a larger whole are critically important to the ability to find meaning and cope with terminal illness. Such goals may be generated by a number of sources, including connectedness with others, or a sense of the temporal continuity of one's own life despite the disruption posed by severe illness. Didactic discussions and experiential exercises help to facilitate exploration of these various elements in group members' lives. The finite structure of the intervention may also highlight these issues, as people who are faced with similar issues work together in a limited time frame in order to accomplish the goals they set out for themselves.

    Cancer is deemed the century's major health problem, and its increasing growth during the last decades has made experts concerned more than ever. Of all types of cancer, breast cancer is regarded as the second most common disease among women. The aim of this study was to determine the effectiveness of spiritual group therapy on quality of life and spiritual well-being among patients suffering from breast cancer. The present research was carried out between March and June 2011. The sample consisted of 24 participants randomly assigned to 2 groups: an experimental group (n, 12) and a control group (n, 12). All the subjects completed questionnaires on quality of life and spiritual well-being in pretest and posttest. The experimental group received 12 sessions of spiritual group therapy. The results demonstrated improvement in quality of life and spiritual well-being in the experimental group. In conclusion, spiritual group therapy can be used to improve quality of life and spiritual well-being (religious health and existential health) among patients with breast cancer.

    Full Text Available Abstract Background The literature suggests that the distribution of female breast cancer mortality demonstrates spatial concentration. There remains a lack of studies on how the mortality burden may impact racial groups across space and over time. The present study evaluated the geographic variations in breast cancer mortality in Texas females according to three predominant racial groups (non-Hispanic White, Black, and Hispanic females over a twelve-year period. It sought to clarify whether the spatiotemporal trend might place an uneven burden on particular racial groups, and whether the excess trend has persisted into the current decade. Methods The Spatial Scan Statistic was employed to examine the geographic excess of breast cancer mortality by race in Texas counties between 1990 and 2001. The statistic was conducted with a scan window of a maximum of 90% of the study period and a spatial cluster size of 50% of the population at risk. The next scan was conducted with a purely spatial option to verify whether the excess mortality persisted further. Spatial queries were performed to locate the regions of excess mortality affecting multiple racial groups. Results The first scan identified 4 regions with breast cancer mortality excess in both non-Hispanic White and Hispanic female populations. The most likely excess mortality with a relative risk of 1.12 (p = 0.001 occurred between 1990 and 1996 for non-Hispanic Whites, including 42 Texas counties along Gulf Coast and Central Texas. For Hispanics, West Texas with a relative risk of 1.18 was the most probable region of excess mortality (p = 0.001. Results of the second scan were identical to the first. This suggested that the excess mortality might not persist to the present decade. Spatial queries found that 3 counties in Southeast and 9 counties in Central Texas had excess mortality involving multiple racial groups. Conclusion Spatiotemporal variations in breast cancer mortality affected racial

    Full Text Available BACKGROUND: Discrepant data have been published on the incidence and prognostic significance of ESR1 gene amplification in early breast cancer. PATIENTS AND METHODS: Formalin-fixed paraffin-embedded tumor blocks were collected from women with early breast cancer participating in two HeCOG adjuvant trials. Messenger RNA was studied by quantitative PCR, ER protein expression was centrally assessed using immunohistochemistry (IHC and ESR1 gene copy number by dual fluorescent in situ hybridization probes. RESULTS: In a total of 1010 women with resected node-positive early breast adenocarcinoma, the tumoral ESR1/CEP6 gene ratio was suggestive of deletion in 159 (15.7%, gene gain in 551 (54.6% and amplification in 42 cases (4.2%, with only 30 tumors (3% harboring five or more ESR1 copies. Gene copy number ratio showed a significant, though weak correlation to mRNA and protein expression (Spearman's Rho <0.23, p = 0.01. ESR1 clusters were observed in 9.5% (57 gain, 38 amplification of cases. In contrast to mRNA and protein expression, which were favorable prognosticators, gene copy number changes did not obtain prognostic significance. When ESR1/CEP6 gene ratio was combined with function (as defined by ER protein and mRNA expression in a molecular classifier, the Gene Functional profile, it was functional status that impacted on prognosis. In univariate analysis, patients with functional tumors (positive ER protein expression and gene ratio normal or gain/amplification fared better than those with non-functional tumors with ESR1 gain (HR for relapse or death 0.49-0.64, p = 0.003.

    The NASA study activities in preparation for a Space Station began in the early 1970's. The early studies included many in-house NASA and contracted studies. A group of representatives from all the NASA Centers, titled the Space Station Concept Development Group (CDG) was involved in the studies which led to the initiation of the Space Station Program. The CDG studies were performed over a period of approximately one year and consisted of four phases. The initial phase had the objective to determine the functions required of the station as opposed to a configuration. The activities of the second phase were primarily concerned with a sizing of the facilities required for payloads and the resources necessary to support these mission payloads. The third phase of studies was designed to develop a philosophical approach to a number of areas related to autonomy, maintainability, operations and logistics, and verification. The fourth phase of the study was to be concerned with configuration assessment activities.

    Full Text Available BackgroundHigher cancer morbidity and mortality rates for the Indigenous population comparedto the overall Australian population has underlined the critical need to improve accessfor Aboriginal people to cancer treatment services. This paper describes anIndigenous Women’s Cancer Support Group (IWCSG established to supportIndigenous people with cancer and their carers/relatives and to facilitate Aboriginalaccess to cancer screening and treatment. Preliminary findings from an evaluation ofthe group are presented.MethodsThe study employed qualitative research methods to describe IWCSG operations andinvestigate the group’s effectiveness. It included one-on-one interviews with 11Geraldton-based health service providers, the IWCSG coordinator, and 10 womenwho have been linked to IWCSG support, as well as observation of group meetings.ResultsDescriptive outcomes relate to group operations, group effectiveness, group benefitsand future development of the group. A cultural strength of IWCSG is its ability tooperate confidentially behind the scenes, providing emotional support and practicalhelp directly to Indigenous people concerned about privacy and shame issues. Theimportant cultural role IWCSG plays in overcoming communication and othercultural barriers to accessing cancer treatment was unanimously recognised by healthservice providers. Aboriginal women supported by IWCSG spoke about an increasedsense of safety, trust and support in accessing and navigating mainstream cancerservices. A critical issue emerging from the research is the need for further development of effective collaborative working relationships between IWCSGmembers and health service providers.ConclusionsThe IWCSG has the potential to inform an effective model for facilitating Indigenousaccess both to cancer treatment and to mainstream treatment for a variety of healthproblems. Future research is required to explore the applicability of Indigenoussupport groups and to focus on the

    1993-09-01

    Both patients and the medical profession are quick to embrace new technology, particularly when it may replace an existing surgical procedure. Unfortunately, the rapidity of acceptance is rarely associated with careful evaluation. Laparoscopy is a recent example of such widely embraced technology. Studies of laparoscopy that yielded good comparative data to more traditional methods were slow to accrue. This led to the exposure of its shortcomings through governmental reports and the lay press. To prevent this from happening in thoracoscopy, two types of studies are required so that valid conclusions about the new technology can be drawn. The first is an accounting of the new technology as procedures evolve around it. The data collected in such a study should contain basic information, including the indications for the procedure, how it was performed, procedure length, associated complications, and patient outcome. Such information provides a broad profile of the technology, emphasizing from the outset its potential strengths and weaknesses. The second type of study involves a more detailed concurrent comparison of the specific procedures utilizing this technology to the established traditional methods. Such randomized studies help to firmly establish through scientific process the place of the new technology. The Video-Assisted Thoracic Surgery Study Group was organized in early 1992 to address these concerns. From an initial four surgeons the group has grown to include more than 41 institutions. Currently the group is collecting data in a registry and has established three clinical trials to evaluate video-assisted thoracic surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

    Imaging biomarkers (IBs) are integral to the routine management of patients with cancer. IBs used daily in oncology include clinical TNM stage, objective response and left ventricular ejection fraction. Other CT, MRI, PET and ultrasonography biomarkers are used extensively in cancer research and drug development. New IBs need to be established either as useful tools for testing research hypotheses in clinical trials and research studies, or as clinical decision-making tools for use in healthcare, by crossing ‘translational gaps’ through validation and qualification. Important differences exist between IBs and biospecimen-derived biomarkers and, therefore, the development of IBs requires a tailored ‘roadmap’. Recognizing this need, Cancer Research UK (CRUK) and the European Organisation for Research and Treatment of Cancer (EORTC) assembled experts to review, debate and summarize the challenges of IB validation and qualification. This consensus group has produced 14 key recommendations for accelerating the clinical translation of IBs, which highlight the role of parallel (rather than sequential) tracks of technical (assay) validation, biological/clinical validation and assessment of cost-effectiveness; the need for IB standardization and accreditation systems; the need to continually revisit IB precision; an alternative framework for biological/clinical validation of IBs; and the essential requirements for multicentre studies to qualify IBs for clinical use.

    Purpose: To report secondary efficacy endpoints of Radiation Therapy Oncology Group protocol 0247, primary endpoint analysis of which demonstrated that preoperative radiation therapy (RT) with capecitabine plus oxaliplatin achieved a pathologic complete remission prespecified threshold (21%) to merit further study, whereas RT with capecitabine plus irinotecan did not (10%). Methods and Materials: A randomized, phase 2 trial evaluated preoperative RT (50.4 Gy in 1.8-Gy fractions) with 2 concurrent chemotherapy regimens: (1) capecitabine (1200 mg/m{sup 2}/d Monday-Friday) plus irinotecan (50 mg/m{sup 2}/wk × 4); and (2) capecitabine (1650 mg/m{sup 2}/d Monday-Friday) plus oxaliplatin (50 mg/m{sup 2}/wk × 5) for clinical T3 or T4 rectal cancer. Surgery was performed 4 to 8 weeks after chemoradiation, then 4 to 6 weeks later, adjuvant chemotherapy (oxaliplatin 85 mg/m{sup 2}; leucovorin 400 mg/m{sup 2}; 5-fluorouracil 400 mg/m{sup 2}; 5-fluorouracil 2400 mg/m{sup 2}) every 2 weeks × 9. Disease-free survival (DFS) and overall survival (OS) were estimated univariately by the Kaplan-Meier method. Local–regional failure (LRF), distant failure (DF), and second primary failure (SP) were estimated by the cumulative incidence method. No statistical comparisons were made between arms because each was evaluated individually. Results: A total of 104 patients (median age, 57 years) were treated; characteristics were similar for both arms. Median follow-up for RT with capecitabine/irinotecan arm was 3.77 years and for RT with capecitabine/oxaliplatin arm was 3.97 years. Four-year DFS, OS, LRF, DF, and SP estimates for capecitabine/irinotecan arm were 68%, 85%, 16%, 24%, and 2%, respectively. The 4-year DFS, OS, LRF, DF, and SP failure estimates for capecitabine/oxaliplatin arm were 62%, 75%, 18%, 30%, and 6%, respectively. Conclusions: Efficacy results for both arms are similar to other reported studies but suggest that pathologic complete remission is an

    The special study group was activated by a charter letter from Sub-Section Managers of Pile Technology on June 20, 1956. The principal objectives were: to collect the information which is presently available for new reactor design and to determine what information should be developed; to make a guess at pile variables; and to point out development programs which must be pursued to achieve a detailed design start in two years. The study was restricted to graphite moderated reactors with H{sub 2}0, D{sub 2}0, and organic coolants. The program was to determine technical feasibility only and detailed economic considerations were not to be included. This report presents the conclusions of the group and some of the reasoning behind these conclusions.

    In this article we describe the connections between prostate cancer support groups (PCSGs) and men's health literacy and consumer orientation to health care services. The study findings are drawn from participant observations conducted at 16 PCSGs in British Columbia, Canada and 54 individual interviews that focused on men's experiences of attending group meetings. Men's communication and interactions at PCSGs provide important insights for how men talk about and conceptualize health and illness. For example, biomedical language often predominated at group meetings, and men used numbers and measures to engage with risk discourses in linking prostate cancer markers to various treatment options and morbidity and mortality rates. Many groups afforded opportunities for men to interact with health care providers as a means to better understand the language and logic of prostate cancer management. The health literacy skills fostered at PCSGs along with specific group-informed strategies could be mobilized in the men's subsequent clinical consultations. Consumer discourses and strategies to contest power relations with health care professionals underpinned many men's search for prostate cancer information and their commitment to assisting other men. Key were patients' rights, and perhaps responsibility, to compare diverse health products and services in making decisions across the entire trajectory of their prostate cancer. Overall, the study findings reveal PCSGs as having the capacity to contest as well as align with medical expertise and services facilitating men's transition from patient to informed health care consumers. The processes through which this occurs may direct the design of older men's health promotion programs.

    Full Text Available Objective: Despite extensive efforts to raise awareness, Papanicolaou (Pap testing rates among Chinese women living in North America remain low compared with Euro-American women. Although the lower Pap testing rate and ensuing health repercussions among Chinese women are well characterized, mechanisms underlying such health disparities are not. The aim of this study was to use a qualitative approach to delineate such mechanisms. Qualitative approaches to understand constructs within the domain of sexual and reproductive health have been shown to be particularly appropriate, and offer a nuanced view of sexuality that is not afforded by traditional quantitative methods.Method: We carried out two focus groups aimed at exploring how Mandarin-speaking and English-speaking Chinese women experience Pap testing (N = 12. The women were invited to partake in the focus groups from having participated in a large-scale quantitative study. We used content analyses to analyze transcripts and extract themes. Results: The women heavily endorsed Chinese medicine philosophy, conceptualizing physical health holistically, and valuing preventative measures over screening and interceptive measures. Pap testing was described as qualitatively different from other screening procedures, such that women assigned a sexually charged meaning to Pap testing, often discussing it in relation to sexual activity and promiscuity. Women expressed their preference for the compulsory and depersonalized manner that Pap tests are performed in their home country of China, as this lessens the embarrassment associated with undergoing Pap testing. Conclusion: Three mechanisms may contribute to lower Pap testing among Chinese women: preference for Chinese medicine philosophy, perceived sexualization of Pap testing, and the institutionalization of medical care. Implications for improving the reproductive health of Chinese women are discussed.

This study evaluated whether common variants of BRCA1/BRCA2 are associated with progression-free survival (PFS and overall survival (OS in patients with advanced stage sporadic EOC.Experimental Design: The allelic frequency of BRCA1 (2612C>T, P871L-rs799917 and BRCA2 (114A>C, N372H-rs144848 were determined in normal blood DNA from women in Gynecologic Oncology Group (GOG protocol #172 phase III trial with optimally-resected stage III EOC treated with intraperitoneal or intravenous cisplatin and paclitaxel (C+P. Associations between polymorphisms and PFS or OS were assessed. Results: 232 women were included for analyses. African Americans (AA had different distributions for the two polymorphisms from Caucasians and others. For non-AA patients, the genotype for BRCA1 P871L was distributed as 38% for CC, 49% for CT and 13% for TT. Median PFS was estimated to be 31, 21 and 21 months, respectively. After adjusting for cell type, residual disease and chemotherapy regimen, CT/TT genotypes were associated with a 1.40-fold increased risk of disease progression (95% confidence interval [CI]=1.00-1.95, p=0.049. After removing 7 patients with known BRCA1 germline mutations, the hazard ratio (HR was 1.36 (95% CI=0.97-1.91, p=0.073. The association between BRCA1 P871L and OS was not significant (HR =1.25, 95% CI=0.88-1.76, p=0.212. Genotype distribution of BRCA2 N372H among non-AA patients was 50%, 44% and 6% for AA, AC and CC, respectively and there is no evidence that this BRCA2 polymorphism was related to PFS or OS. Conclusion: Polymorphisms in BRCA1 P871L or in BRCA2 N372H were not associated with either PFS or OS in women with optimally-resected, stage III EOC treated with cisplatin and paclitaxel.

    2015-03-01

    Lung cancer is the leading cause of cancer-related death worldwide. In 2011, the largest lung cancer screening trial worldwide, the US National Lung Screening Trial, published a 20% decrease in lung cancer-specific mortality in the computed tomography (CT)-screened group, compared with the group screened by chest x-ray. On the basis of this trial, different US guidelines recently have recommended CT lung cancer screening. However, several questions regarding the implementation of lung cancer screening need to be answered. In Europe, several lung cancer screening trials are ongoing. It is planned to pool the results of the lung cancer screening trials in European randomized lung cancer CT screening (EUCT). By pooling of the data, EUCT hopes to be able to provide additional information for the discussion of some important issues regarding the implementation of lung cancer screening by low-dose CT, including: the determination of the optimal screen population, the comparison between a volume-based and diameter-based nodule management protocol, and the determination of optimal screen intervals.

    Full Text Available Abstract Background Colon cancer is a public health problem worldwide. Adjuvant chemotherapy after surgical resection for stage III colon cancer has been shown to improve both progression-free and overall survival, and is currently recommended as standard therapy. However, its value for patients with stage II disease remains controversial. When this study was designed 5-fluorouracil (5FU plus leucovorin (LV was standard adjuvant treatment for colon cancer. Irinotecan (CPT-11 is a topoisomerase I inhibitor with activity in metastatic disease. In this multicenter adjuvant phase III trial, we evaluated the addition of irinotecan to weekly 5FU plus LV in patients with stage II or III colon cancer. Methods The study included 873 eligible patients. The treatment consisted of weekly administration of irinotecan 80 mg/m2 intravenously (IV, LV 200 mg/m2 and 5FU 450 mg/m2 bolus (Arm A versus LV 200 mg/m2 and 5FU 500 mg/m2 IV bolus (Arm B. In Arm A, treatments were administered weekly for four consecutive weeks, followed by a two-week rest, for a total of six cycles, while in Arm B treatments were administered weekly for six consecutive weeks, followed by a two-week rest, for a total of four cycles. The primary end-point was disease-free survival (DFS at three years. Results The probability of overall survival (OS at three years was 0.88 for patients in Arm A and 0.86 for those in Arm B, while the five-year OS probability was 0.78 and 0.76 for patients in Arm A and Arm B, respectively (P = 0.436. Furthermore, the probability of DFS at three years was 0.78 and 0.76 for patients in Arm A and Arm B, respectively (P = 0.334. With the exception of leucopenia and neutropenia, which were higher in patients in Arm A, there were no significant differences in Grades 3 and 4 toxicities between the two regimens. The most frequently recorded Grade 3/4 toxicity was diarrhea in both treatment arms. Conclusions Irinotecan added to weekly bolus 5FU plus LV did not result

    1998-01-01

    Full Text Available The need for high quality management information within the contracting process has driven many of the major developments in health service computing. These have often merged clinical and financial requirements, usually along patient-centred lines. In order to identify a common currency for a range of clinical activities that are inherently variable, price tariffs have been drawn up on the basis of 'episodes of care' within specialties. Healthcare Resource Groups (HRGs were designed to meet the need for a common information currency. However, they were designed for acute care. The study on which this paper is based aims to examine their applicability to chronic care in a cancer specialist unit. The data were drawn from the patient information system within a major cancer unit. The focus of the investigation is encapsulated in the following questions: a Do HRGs really work as a grouping and costing methodology? b How relevant are HRG classifications for long-term patient care? The investigation demonstrated that not all HRGs are iso-resource within this environment. The findings from the data analysis are echoed by the NHS Executive's own evaluation . This does not negate advantages in their use. Furthermore, the development of Health Benefit Groups as information management tools, through a focus on health conditions and interventions rather than on purely on treatments, offers potential for greater validity within a chronic care situation.

The patients’ mean age was 44.3±2.1 years. A control group consisted of 20 healthy women matched for age. Before treatment, the authors determined the blood levels of adrenocorticotropic hormone and cortisol by radiometric assay and the content of daily excreted cortisol, cortisone, tetrahydrocortisol, tetrahydrocortisone, 11-hydroxy-17-ketosteroids, estrone, estradiol, and pregnanediol by the conventional classical studies.The nature of the impaired synthesis and metabolism of sex and adrenocorticoid hormones and their degree have been found to coincide, which suggest that it is expedient to use these findings to form EC risk groups in patients with AEH in the late reproductive period.

    The international study group on data preservation in High Energy Physics, DPHEP, achieved a major milestone in 2012 with the publication of its eagerly anticipated large-scale report [1]. This document contains a description of data preservation activities from all major high energy physics collider-based experiments and laboratories. A central message of the report is that data preservation in HEP is not possible without long term investment in not only hardware but also human resources, and with this in mind DPHEP will evolve to a new collaboration structure in 2013. This paper describes the progress made since the publication of that report – shortly before CHEP 2012 – as well as the future working directions of the new collaboration.

    Growing evidence suggests that phospholipase A2 (PLA2) plays a pivotal role in tumorigenesis in human gastrointestinal cancer. One of the well-studied isoforms of PLA2, group IIA PLA2 (PLA2G2A), appears to exert its protumorigenic or antitumorigenic effects in a tissue-specific manner. The present study was designed to determine the expression profile and prognostic value of PLA2G2A in gastric cancer in a large Chinese cohort. By using real-time polymerase chain reaction, the amount of PLA2G2A messenger RNA in 60 pairs of fresh gastric tumors and adjacent noncancerous mucosa was measured. The immunostaining of PLA2G2A in 866 gastric cancers with paired noncancerous tissues was assayed. No expression of PLA2G2A was found in normal gastric mucosa, and focal expression of PLA2G2A was noticed in intestinal metaplasia, whereas significantly increased expression of PLA2G2A was observed in the cytoplasm of gastric cancer cells. Furthermore, the extent of PLA2G2A expression was associated with tumor size (P gastric cancer. Multivariate analysis showed that PLA2G2A expression was an independent predictor of survival for patients with gastric cancer (P = .024). Expression of PLA2G2A seems to be protective for patients with gastric cancer (hazard ratio, 1.423; 95% confidence interval, 1.047-1.935), and it may be a target for achieving better treatment outcomes.

  10. The causality between smoking and lung cancer among groups and individuals: addressing issues in tobacco litigation in South Korea

    Khang, Young-Ho

    2015-01-01

    This article discusses issues on the causality between smoking and lung cancer, which have been raised during the tobacco litigation in South Korea. It should be recognized that the explanatory ability of risk factor(s) for inter-individual variations in disease occurrence is different from the causal contribution of the risk factor(s) to disease occurrence. The affected subjects of the tobacco litigation in South Korea are lung cancer patients with a history of cigarette smoking. Thus, the attributable fraction of the exposed rather than the population attributable fraction should be used in the tobacco litigation regarding the causal contribution of smoking to lung cancer. Scientific evidence for the causal relationship between smoking and lung cancer is based on studies of individuals and groups, studies in animals and humans, studies that are observational or experimental, studies in laboratories and communities, and studies in both underdeveloped and developed countries. The scientific evidence collected is applicable to both groups and individuals. The probability of causation, which is calculated based on the attributable fraction for the association between smoking and lung cancer, could be utilized as evidence to prove causality in individuals.

    External carcinogens, such as tobacco and alcohol, induce molecular changes in large areas of oral mucosa, which increase the risk of malignant transformation. This condition, known as 'field cancerization', can be detected in biopsy specimens using histochemical techniques, even before histological alterations are identified. The efficacy of these histochemical techniques as biomarkers of early cancerization must be demonstrated in appropriate models. The hamster cheek pouch oral cancer model, universally employed in biological studies and in studies for the prevention and treatment of oral cancer, is also an excellent model of field cancerization. The carcinogen is applied in solution to the surface of the mucosa and induces alterations that recapitulate the stages of cancerization in human oral mucosa. We have demonstrated that the following can be used for the early detection of cancerized tissue: silver staining of nucleolar organizer regions; the Feulgen reaction to stain DNA followed by ploidy analysis; immunohistochemical analysis of fibroblast growth factor-2, immunohistochemical labeling of proliferating cells to demonstrate an increase of epithelial cell proliferation in the absence of inflammation; and changes in markers of angiogenesis (i.e. those indicating vascular endothelial growth factor activity, endothelial cell proliferation and vascular density). The hamster cheek pouch model of oral cancer was also proposed and validated by our group for boron neutron capture therapy studies for the treatment of oral cancer. Clinical trials of this novel treatment modality have been performed and are underway for certain tumor types and localizations. Having demonstrated the efficacy of boron neutron capture therapy to control tumors in the hamster cheek pouch oral cancer model, we adapted the model for the long-term study of field cancerized tissue. We demonstrated the inhibitory effect of boron neutron capture therapy on tumor development in field

    Despite the advances in the treatment of cancer, mortality is still high. Complementary and alternative medicine is emerging as a potent modality in cancer treatment. 'Swarna Bhasma' (SB), containing gold particles, is an ancient Indian medicine has shown its anticancer activity. This present study was conducted to detect the effect of SB on solid malignancies. A total of 43 patients were included in this study received SB for 1 year. Seventeen patients showed response. The response was best in rectal cancer group 70% (7/10). Nearly 41.02% patients survived for 1 year after treatment but after 5 years this came down to 15.38%.

    Full Text Available Abstract Background Altered tryptophan metabolism and indoleamine 2,3-dioxygenase activity are linked to cancer development and progression. In addition, these biological factors have been associated with the development and severity of neuropsychiatric syndromes, including major depressive disorder. However, this biological mechanism associated with both poor disease outcomes and adverse neuropsychiatric symptoms has received little attention in women with breast cancer. Therefore, a pilot study was undertaken to compare levels of tryptophan and other proteins involved in tryptophan degradation in women with breast cancer to women without cancer, and secondarily, to examine levels in women with breast caner over the course of chemotherapy. Findings Blood samples were collected from women with a recent diagnosis of breast cancer (n = 33 before their first cycle of chemotherapy and after their last cycle of chemotherapy. The comparison group (n = 24 provided a blood sample prior to breast biopsy. Plasma concentrations of tryptophan, kynurenine, and tyrosine were determined. The kynurenine to tryptophan ratio (KYN/TRP was used to estimate indoleamine 2,3-dioxygenase activity. On average, the women with breast cancer had lower levels of tryptophan, elevated levels of kynurenine and tyrosine and an increased KYN/TRP ratio compared to women without breast cancer. There was a statistically significant difference between the two groups in the KYN/TRP ratio (p = 0.036, which remained elevated in women with breast cancer throughout the treatment trajectory. Conclusions The findings of this pilot study suggest that increased tryptophan degradation may occur in women with early-stage breast cancer. Given the multifactorial consequences of increased tryptophan degradation in cancer outcomes and neuropsychiatric symptom manifestation, this biological mechanism deserves broader attention in women with breast cancer.

    Recommendations for specimen collection and handling have been developed for adoption across breast cancer clinical trials conducted by the Breast International Group (BIG)-sponsored Groups and the National Cancer Institute (NCI)-sponsored North American Cooperative Groups. These recommendations are meant to promote identifiable standards for specimen collection and handling within and across breast cancer trials, such that the variability in collection/handling practices that currently exists is minimized and specimen condition and quality are enhanced, thereby maximizing results from specimen-based diagnostic testing and research. Three working groups were formed from the Cooperative Group Banking Committee, BIG groups, and North American breast cancer cooperative groups to identify standards for collection and handling of (1) formalin-fixed, paraffin-embedded (FFPE) tissue; (2) blood and its components; and (3) fresh/frozen tissue from breast cancer trials. The working groups collected standard operating procedures from multiple group specimen banks, administered a survey on banking practices to those banks, and engaged in a series of discussions from 2005 to 2007. Their contributions were synthesized into this document, which focuses primarily on collection and handling of specimens to the point of shipment to the central bank, although also offers some guidance to central banks. Major recommendations include submission of an FFPE block, whole blood, and serial serum or plasma from breast cancer clinical trials, and use of one fixative and buffer type (10% neutral phosphate-buffered formalin, pH 7) for FFPE tissue across trials. Recommendations for proper handling and shipping were developed for blood, serum, plasma, FFPE, and fresh/frozen tissue.

    Full Text Available Aims: To analyze the impact of two cancer support groups in the treatment and abandonment of childhood cancer. Materials and Methods: This is a retrospective review of children with cancer funded and non-funded who were treated at Kanchi Kamakoti CHILDS Trust Hospital from 2010 to 2013. A total of 100 patients were funded, 57 by Ray of Light Foundation and 43 by Pediatric Lymphoma Project and 70 non-funded. Results: The total current survival of 80%, including those who have completed treatment and those currently undergoing treatment, is comparable in both the groups. Abandonment of treatment after initiating therapy was not seen in the financially supported group whereas abandonment of treatment after initiation was seen in one child in the non-funded group. Conclusions: Besides intensive treatment with good supportive care, financial support also has an important impact on compliance and abandonment in all socioeconomic strata of society. Financial support from private cancer support groups also has its impact beyond the patient and family, in reducing the burden on government institutions by non-governmental funding in private sector. Improvement in the delivery of pediatric oncology care in developing countries could be done by financial support from the private sector.

    Cancer and Leukemia Group B 19808 (CALGB 19808) is the only randomized trial of a second-generation P-glycoprotein (Pgp) modulator in untreated patients with acute myeloid leukemia (AML) younger than age 60 years. We randomly assigned 302 patients to receive induction chemotherapy regimens consisting of cytosine arabinoside (Ara-C; A), daunorubicin (D), and etoposide (E), without (ADE) or with (ADEP) PSC-833 (P). The incidence of complete remission was 75% with both regimens. Reversible grade 3 and 4 liver and mucosal toxicities were significantly more common with ADEP. Therapy-related mortality was 7% and did not differ by induction arm. Excess cardiotoxicity was not seen with high doses of D in ADE. The median disease-free survival was 1.34 years in the ADE arm and 1.09 years in the ADEP arm (P = .74, log-rank test); the median overall survival was 1.86 years in the ADE arm and 1.69 years in the ADEP arm (P = .82). There was no evidence of a treatment difference within any identifiable patient subgroup. Inhibition of Pgp-mediated drug efflux by PSC-833 did not improve clinical outcomes in younger patients with untreated AML. This trial was registered at www.clinicaltrials.gov as #NCT00006363.

    The aim of this paper was to establish the demographic profile of an at-risk group for skin cancer and to assess the preventive measures taken by the studied individuals and by the employer. The methods chosen was a quantitative study with a sample of 33 mail carriers from the Empresa Brasileira de Correios e Telégrafos in Botucatu, Brazil. Information regarding the demographic profile, how long the individual had been working for the company, hours of sun exposure, history of sunburns, family cancer history and skin cancer prevention strategies used by the company was collected by means of a questionnaire. The data were analyzed using Fisher's Exact Test at a 5% probability. The predominant age groups were 26-30 and 31-35 years corresponding to 42,42%. The predominant skin color was white (93,94%) and 81,82% of the studied individuals were working in the company for over five years. 63,63% of the interviewees use sunscreen habitually; those who do not explain this with a lack of habit (in 75% of the cases). As refers to supply of protective equipment by the company, 100% of the subjects answered positively. These findings allow characterizing the studied population as a skin cancer risk group. Prophylactic measures in form of educational actions for awareness building should be adopted and stimulated.

    Purpose: To evaluate the rate of gastrointestinal (GI) toxicity of neoadjuvant chemoradiation with capecitabine, oxaliplatin, and intensity modulated radiation therapy (IMRT) in cT3-4 rectal cancer. Methods and Materials: Patients with localized, nonmetastatic T3 or T4 rectal cancer <12 cm from the anal verge were enrolled in a prospective, multi-institutional, single-arm study of preoperative chemoradiation. Patients received 45 Gy with IMRT in 25 fractions, followed by a 3-dimensional conformal boost of 5.4 Gy in 3 fractions with concurrent capecitabine/oxaliplatin (CAPOX). Surgery was performed 4 to 8 weeks after the completion of therapy. Patients were recommended to receive FOLFOX chemotherapy after surgery. The primary endpoint of the study was acute grade 2 to 5 GI toxicity. Seventy-one patients provided 80% probability to detect at least a 12% reduction in the specified GI toxicity with the treatment of CAPOX and IMRT, at a significance level of .10 (1-sided). Results: Seventy-nine patients were accrued, of whom 68 were evaluable. Sixty-one patients (89.7%) had cT3 disease, and 37 (54.4%) had cN (+) disease. Postoperative chemotherapy was given to 42 of 68 patients. Fifty-eight patients had target contours drawn per protocol, 5 patients with acceptable variation, and 5 patients with unacceptable variations. Thirty-five patients (51.5%) experienced grade ≥2 GI toxicity, 12 patients (17.6%) experienced grade 3 or 4 diarrhea, and pCR was achieved in 10 patients (14.7%). With a median follow-up time of 3.98 years, the 4-year rate of locoregional failure was 7.4% (95% confidence interval [CI]: 1.0%-13.7%). The 4-year rates of OS and DFS were 82.9% (95% CI: 70.1%-90.6%) and 60.6% (95% CI: 47.5%-71.4%), respectively. Conclusion: The use of IMRT in neoadjuvant chemoradiation for rectal cancer did not reduce the rate of GI toxicity.

    Significant differences in the incidence levels of lung cancer have been observed among major Chinese dialect groups or communities (Kokkien, Teochew and Cantonese) in Singapore. Among males, the incidence rate is highest in the Hokkiens (age-standardized incidence rate per 100,000 persons per year in Hokkien 67.8, Teochew 55.3, Cantonese 54.0) and among females, it is highest in the Cantonese (Hokkien 12.4, Teochew 12.8, Cantonese 27.2). The present investigation was undertaken to determine the incidence rates of each of the main histological types of lung cancer in the Chinese population and to determine whether there are any correlations between histological patterns and the dialect group differentials that may be of aetiological significance. During the period 1968-1972, a total of 1,747 cases of lung cancer (1,285 males and 462 females) were reported to the Singapore Cancer Registry. It proved possible to type the neoplasms histologically in 476 males (37.0%) and 154 females (33.3%). Age-standardized rates by histological type were computed on the assumption that those histologically typed were a representative sample of all lung cancers. This study shows that Hokkien males have a significantly higher incidence rate of epidermoid carcinoma than the other dialect groups (Hokkien 36.1, Teochew 21.1, Cantonese 17.3). The Cantonese females have significantly higher incidence rates of both epidermoid carcinoma (Hokkien 3.7, Teochew 2.3, Cantonese 5.9) and adenocarcinoma (Hokkien 4.6, Teochew 3.6, Cantonese 11.9). Various sources of bias in studied of this type were examined; it is concluded that the differences in the histologic-specific incidence rates of lung cancer among the various Chinese dialect groups in Singapore are real and not artefactual. The significance of these findings in relation to possible aetiological factors is discussed.

    Employing the stress and coping theory of Lazarus and Folkman, this study followed 117 women age 40 or over regarding personality, cognitive appraisal, coping, and mood variables before breast biopsy, after diagnosis, and, for those who had cancer, after surgery. Upon biopsy, 36 received a cancer diagnosis, and 81 received a benign diagnosis. The 2 groups did not differ on appraisals, coping, or affect before diagnosis. With prebiopsy affect controlled, cancer patients reported more negative affect postbiopsy than did benign patients. Postsurgery, cancer patients expressed less vigor and more fatigue than benign patients, but the groups did not differ on other negative emotions. Prebiopsy, psychosocial predictors accounted for 54% and 29% of the variance in negative and positive emotion, respectively. Prebiopsy variables also predicted postbiopsy and postsurgery mood; cognitive avoidance coping was a particularly important predictor of high distress and low vigor.

    A stratified random sample of 176 men was taken from a larger community prostate study group of 1405 eligible subjects from three ethnic groups in the Wellington region of New Zealand, in order to examine ethnic differences in exposure to cadmium (Cd), selenium (Se) and zinc (Zn) and possible associations of blood levels of Cd, Se and Zn with the prevalence of elevated serum Prostate Specific Antigen (PSA); a marker of prostate cancer. Maori and Pacific Islands men were found likely to have higher Cd exposure than New Zealand Europeans through diet, occupation and smoking. However, there was no significant difference between ethnic groups in mean blood Cd levels. Pacific Islands men had significantly higher levels of blood Se than both New Zealand European men and Maori men. Maori men had significantly higher levels of blood Zn than both New Zealand European men and Pacific Islands men. A positive association was found between blood Cd and total serum PSA. Se and Zn levels were not associated with elevated PSA. Maori and Pacific Islands men have higher prostate cancer mortality rates than New Zealand European men. Ethnic differences in mortality could be contributed to by differences in rates of disease progression, influenced by exposure and/or deficiency to trace elements. However, results did not reflect a consistent ethnic trend and highlight the complexity of the risk/protective mechanisms conferred by exposure factors. Further research is needed to ascertain whether the associations found between Cd and PSA levels are biologically important or are merely factors to be considered when interpreting PSA results clinically.

    Background Hereditary nonpolyposis colorectal cancer (HNPPC) is one of the most common genetic syndrome related with mutation of human mismatch repair genes. This study was to evaluate the clinical significance of suspected hereditary nonpolyposis colorectal cancer (sHNPCC) criteria I and the clinical and genetic features of International Collaborative Group-HNPCC (ICG-HNPCC) and sHNPCC families.Methods Twenty-nine ICG-HNPCC families fulfilling the Amsterdam criteria and 34 sHNPCC families fulfilling the sHNPCC criteria I were collected. PCR-SSCP and DNA sequencing analysis were employed to screen the germline mutations of the hMLH1 and hMSH2 genes in these families.Results The ICG group had more colorectal cancer (CRC) patients per family than did the suspected group (P0.05), mutation type, and mutation distribution. Comparison of the families with and without mutation showed no significant difference in CRC patients per family, Lynch classification, and tumor spectrum.Conclusions ICG-HNPCC and sHNPCC families that have similar clinical manifestations and genetic basis indicate a similar nature for cancer development. The application of sHNPCC criteria I will facilitate clinical diagnosis and treatment of small families.

    Full Text Available Background: Sexual dysfunction in breast cancer patients is considered as a common and distressing problem. Considering the increasing number of breast cancer survivors living for longer periods of time with the disease and the importance of their quality of life, we conducted the present study to compare the sexual functioning in breast cancer patients with their healthy counterparts.Methods: In this case-control study, breast cancer patients who completed their treatment protocol and were followed up for at least six months were included. The controls were healthy women with normal clinical breast examinations. All subjects filled-in the Persian version of Female Sexual Function Index questionnaire.Results: A total of 165 subjects including 71 breast cancer patients and 94 healthy women were studied. The frequency of sexual dysfunction in cases and controls was 52.6% and 47.4%, respectively (P = 0.09. There were no significant differences between the two groups regarding domain scores, except for vaginal lubrication (P = 0.045. Logistic regression analysis indicated that significant determinants of sexual dysfunction in breast cancer group was patients' age (OR = 4.0, 95%CI: 1.3 – 11.5, P = 0.01 and age of the spouse (OR= 9.8, 95% CI: 1.8-51.9, P= 0.007, while in controls, only emotional relationship with the husband was the significant predictive factor (OR = 6.3, 95%CI: 1.9 – 20.5, P = 0.002.Conclusions: Our findings indicated that sexual dysfunction is prevalent in Iranian women regardless of their physical health status. The frequency of vaginal dryness in breast cancer patients was significantly higher than controls. Age of the patient and the spouse (>40 were the only significant predictors of sexual dysfunction among women with breast cancer. Preventive strategies, sexual education and access to effective treatment should be planned in supportive care of breast cancer patients.

    Inherited genetic polymorphisms within immune response genes have been shown to associate with risk of invasive cervical cancer (ICC) and its immediate precursor, cervical intraepithelial neoplasia grade 3. Here, we used the transmission/disequilibrium test to detect disease-liability alleles and investigate haplotype transmission of KIR and HLA class I polymorphisms in a large family-based population of women with cervical cancer and their biological parents (359 trios). The effect of distinct human papillomavirus types was also explored. HLA-Cw group 1 (HLA-Cw alleles with asparagine at position 80), which serves as ligand for certain killer immunoglobulin-like receptors (KIR), was significantly overtransmitted in women with ICC (P = 0.04), and particularly in the subgroup of women infected with high risk HPV16 or 18 subtypes (P = 0.008). These data support the involvement of the HLA-C locus in modulating the risk of cervical neoplasia perhaps through its function as ligands for KIR, but functional studies are essential to confirm this hypothesis.

    Numerous antinuclear demonstrations reveal that the public is anxious about the potential health effects caused by nuclear power plants. The purpose of this study is to address the question "Is there a higher cancer incidence rate in the vicinity of nuclear power plants in Taiwan?" The Taiwan Cancer Registry database from 1979 to 2003 was used to compare the standardized incidence rate of the top four cancers with strong evidence for radiation risks between the "plant-vicinity" with those "non-plant-vicinity" groups. All cancer sites, five-leading cancers in Taiwan, and gender-specific cancers were also studied. We also adopted different observation time to compare the incidence rate of cancers between two groups to explore the impact of the observation period. The incidences of leukemia, thyroid, lung, and breast cancer were not significantly different between two groups, but cervix uteri cancer showed higher incidence rates in the plant-vicinity group. The incidence of cervical cancer was not consistently associated with the duration of plant operation, according to a multiyear period comparison. Although there was higher incidence in cervix cancer in the plant-vicinity group, our findings did not provide the crucial evidence that nuclear power plants were the causal factor for some cancers with strong evidence for radiation risks.

    The primary objective was to compare the 3-year survival of rectal cancer patients randomised postoperatively to irinotecan (IRI), Leucovorin (LV) and bolus 5-fluorouracil (5FU) or LV-bolus 5FU with radiotherapy. Secondary objectives included disease-free survival, local relapse and toxicity. The study included 321 eligible patients. The treatment consisted of weekly administration of IRI 80 mg/m(2) intravenously (IV), LV 200 mg/m(2) and 5FU 450 mg/m(2) bolus (arm A) versus LV 200 mg/m(2) and 5FU 450 mg/m(2) IV bolus (arm B). One cycle included four infusions and treatment was continued for a total of six cycles. The first cycle was followed by pelvic irradiation plus 5FU. There were no differences between the arms in 3-year overall, disease-free and local relapse-free survival. Grades 3 and 4 toxicity was similar in both the arms with the exception of leucopaenia, neutropaenia and alopecia, which were higher in the IRI arm. IRI added to adjuvant radiochemotherapy with LV and bolus 5FU was not shown to improve survival, whereas the incidence of severe leucopaenia was significantly higher in the IRI arm.

    Objective: To evaluate the clinical value of serum tumor supplied group of factor (TSGF) in diagnosis of epithelial ovarian cancer. Methods: The serum TSGF was tested in 69 patients with epithelial ovarian cancer, 28 patients with benign ovarian lesion and 61 healthy women. The serum levels of vascular endothelial growth factor (VEGF) and CA125 were determined in patients with epithelial ovarian cancer and in those with benign ovarian lesion. The correlations of TSGF with VEGF and CA125 were investigated. Results: The serum level of TSGF in patients with epithelial ovarian cancer was obviously higher than in patients with benign ovarian lesion and in healthy women (P0.05). The serum level of TSGF and VEGF and CA125 in patients with epithelial ovarian cancer showed positive correlation (P<0.01, P<0.05, respectively). Conclusion: There is no marked difference in diagnostic value among TSGF, VEGF and CA125. TSGF has a certain value in diagnosis of epithelial ovarian cancer, and is helpful to distinguish epithelial ovarian cancer from benign ovarian lesion.

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

    Full Text Available We investigated the significance of high- mobility group box1 (HMGB1 and T-cell-mediated immunity and prognostic value in cervical cancer. HMGB1, forkhead/winged helix transcription factor p3 (Foxp3, IL-2, and IL-10 protein expression was analyzed in 100 cervical tissue samples including cervical cancer, cervical intraepithelial neoplasia (CIN, and healthy control samples using immunohistochemistry. Serum squamous cell carcinoma antigen (SCC-Ag was immunoradiometrically measured in 32 serum samples from 37 cases of squamous cervical cancer. HMGB1 and SCC-Ag were then correlated to clinicopathological characteristics. HMGB1 expression tends to increase as cervical cancer progresses and it was found to be significantly correlated to FIGO stage and lymph node metastasis. These findings suggest that HMGB1 may be a useful prognostic indicator of cervical carcinoma. In addition, there were significant positive relationships between HMGB1 and FOXP3 or IL-10 expression (both p < 0.05. In contrast, HMGB1 and IL-2 expression was negatively correlated (p < 0.05. HMGB1 expression may activate Tregs or facilitate Th2 polarization to promote immune evasion of cervical cancer. Elevated HMGB1 protein in cervical carcinoma samples was associated with a high recurrence of HPV infection in univariate analysis (p < 0.05. HMGB1 expression and levels of SCC-Ag were directly correlated in SCC (p < 0.05. Thus, HMGB1 may be a useful biomarker for patient prognosis and cervical cancer prediction and treatment.

    Full Text Available Background: The ABO blood group antigens are present on the surface of red blood cells and various epithelial cells. As the majority of human cancers are derived from epithelial cells, changes in blood group antigens constitute an important aspect of human cancers. The aim of the study was to establish clinical usefulness of ABO blood group as a predisposing factor in early diagnosis and management of patients with oral precancerous lesions/conditions. Materials and Methods: The study sample consisted of 50 control and 50 oral precancer (25 leukoplakia and 25 Oral Submucous Fibrosis confirmed by histopathologic examination. All samples were subjected to blood group testing and their prevalence was compared by Z-test using STATA version 8. Results: The "A" blood group was prevalent among the precancerous group. Significant differences on prevalences of blood groups were found (P < 0.05 between control versus leukoplakia and OSMF. Interestingly, 24% gutka chewers who had higher number of grades of dysplasia were falling in "A" blood group. Conclusion: Blood group type should be considered along with other risk factors to understand the individual patient′s risk and further studies in larger samples with inclusion of Rh factor is needed to elucidate the relationship with ABO blood group types.

    Experimental studies have consistently shown the inhibitory activities of tea extracts on tumorigenesis in multiple model systems. Epidemiological studies, however, have produced inconclusive results in humans. A comprehensive review was conducted to assess the current knowledge on tea consumption and risk of cancers in humans. In general, consumption of black tea was not associated with lower risk of cancer. High intake of green tea was consistently associated with reduced risk of upper gastrointestinal tract cancers after sufficient control for confounders. Limited data support a protective effect of green tea on lung and hepatocellular carcinogenesis. Although observational studies do not support a beneficial role of tea intake on prostate cancer risk, phase II clinical trials have demonstrated an inhibitory effect of green tea extract against the progression of prostate pre-malignant lesions. Green tea may exert beneficial effects against mammary carcinogenesis in premenopausal women and recurrence of breast cancer. There is no sufficient evidence that supports a protective role of tea intake on the development of cancers of the colorectum, pancreas, urinary tract, glioma, lymphoma, and leukemia. Future prospective observational studies with biomarkers of exposure and phase III clinical trials are required to provide definitive evidence for the hypothesized beneficial effect of tea consumption on cancer formation in humans.

    Curative therapy for childhood and adolescent cancer translates to 1 in 640 young adults being a survivor of cancer. Although acute hepato-biliary toxicity occurs commonly during pediatric cancer therapy, the impact of antineoplastic therapy on long-term liver health in childhood/adolescent cancer survivors is unknown. This article reviews the medical literature on late liver dysfunction following treatment for childhood/adolescent cancer. We also outline the Children's Oncology Group (COG) guidelines for screening and follow-up of hepato-biliary sequelae. As the population of survivors grow and age, vigilance for risks to hepatic health needs to continue based on specific exposures during curative cancer therapy.

    A retrospective cohort study was undertaken to examine the cancer morbidity in a group of 759 furniture makers of the Neubrandenburg District. During the study interval of 1973 to 1984, a total of 40 malignant tumors occurred in the exposed group. Except for bronchial cancer (SIR = 68) and prostate cancer (SIR = 43), all observed tumors were overrepresented in comparison to the incidence of such illnesses in the normal population of the study area. Significantly increased SIRs occurred for malignant melanoma (2 cases, SIR = 952) and for rectal cancer (6 cases, SIR = 239). Malignant tumors of the nose and paranasal sinuses were not observed.

    In genome-wide association studies, penalization is an important approach for identifying genetic markers associated with disease. Motivated by the fact that there exists natural grouping structure in single nucleotide polymorphisms and, more importantly, such groups are correlated, we propose a new penalization method for group variable selection which can properly accommodate the correlation between adjacent groups. This method is based on a combination of the group Lasso penalty and a quadratic penalty on the difference of regression coefficients of adjacent groups. The new method is referred to as smoothed group Lasso (SGL). It encourages group sparsity and smoothes regression coefficients for adjacent groups. Canonical correlations are applied to the weights between groups in the quadratic difference penalty. We first derive a GCD algorithm for computing the solution path with linear regression model. The SGL method is further extended to logistic regression for binary response. With the assistance of the majorize-minimization algorithm, the SGL penalized logistic regression turns out to be an iteratively penalized least-square problem. We also suggest conducting principal component analysis to reduce the dimensionality within groups. Simulation studies are used to evaluate the finite sample performance. Comparison with group Lasso shows that SGL is more effective in selecting true positives. Two datasets are analyzed using the SGL method.

    Full Text Available Long-term follow-up studies of asbestos-related cancer in shipbreaking workers are lacking. This study examines the relationship between cancer incidence and asbestos exposure among former Taiwan shipbreaking workers.A total of 4,427 shipbreaking workers and 22,135 population-based matched controls were successfully followed in this study. The study cohort was linked to the Taiwan Cancer Registry for new cancer cases. The adjusted hazard ratio (aHR for cancer was calculated for the shipbreaking workers with Total Exposure Potential Scores (TEP for asbestos.Follow-up generated 109,932 person-years, with 940 deaths and 436 cancer cases, among 4,427 shipbreaking workers from 1985 to 2008. The high asbestos exposure group also had a statistically significant increase in the risk of overall cancer (aHR= 1.71; 95% CI: 1.42-2.05, esophagus cancer (aHR= 2.31; 95% CI: 1.00-5.41, liver and intrahepatic bile duct cancer (aHR= 1.60; 95% CI: 1.08-2.36, and trachea, bronchus, and lung cancer (aHR= 3.08; 95% CI: 1.80-5.25. Mesothelioma cases were found in the high asbestos exposure group. Moreover, overall cancer, esophagus cancer, and trachea, bronchus, and lung cancer were seen in a dose-dependent relationship with asbestos exposure.This study presented the elevated trend of asbestos exposure with cancer incidence for overall cancer, esophagus cancer, and trachea, bronchus, and lung cancer among shipbreaking workers. Those workers previously exposed to asbestos should receive persistent monitoring in order to early detect adverse health outcomes.

  15. Finding Combination of Features from Promoter Regions for Ovarian Cancer-related Gene Group Classification

    KAUST Repository

    Olayan, Rawan S.

    2012-12-01

    In classification problems, it is always important to use the suitable combination of features that will be employed by classifiers. Generating the right combination of features usually results in good classifiers. In the situation when the problem is not well understood, data items are usually described by many features in the hope that some of these may be the relevant or most relevant ones. In this study, we focus on one such problem related to genes implicated in ovarian cancer (OC). We try to recognize two important OC-related gene groups: oncogenes, which support the development and progression of OC, and oncosuppressors, which oppose such tendencies. For this, we use the properties of promoters of these genes. We identified potential “regulatory features” that characterize OC-related oncogenes and oncosuppressors promoters. In our study, we used 211 oncogenes and 39 oncosuppressors. For these, we identified 538 characteristic sequence motifs from their promoters. Promoters are annotated by these motifs and derived feature vectors used to develop classification models. We made a comparison of a number of classification models in their ability to distinguish oncogenes from oncosuppressors. Based on 10-fold cross-validation, the resultant model was able to separate the two classes with sensitivity of 96% and specificity of 100% with the complete set of features. Moreover, we developed another recognition model where we attempted to distinguish oncogenes and oncosuppressors as one group from other OC-related genes. That model achieved accuracy of 82%. We believe that the results of this study will help in discovering other OC-related oncogenes and oncosuppressors not identified as yet.

    Full Text Available Abstract Background Cancer risks of migrants might differ from risks of the indigenous population due to differences in socioeconomic status, life style, or genetic factors. The aim of this study was to investigate cancer patterns among children of Turkish descent in Germany. Methods We identified cases with Turkish names (as a proxy of Turkish descent among the 37,259 cases of childhood cancer registered in the German Childhood Cancer Registry (GCCR during 1980–2005. As it is not possible to obtain reference population data for children of Turkish descent, the distribution of cancer diagnoses was compared between cases of Turkish descent and all remaining (mainly German cases in the registry, using proportional cancer incidence ratios (PCIRs. Results The overall distribution of cancer diagnoses was similar in the two groups. The PCIRs in three diagnosis groups were increased for cases of Turkish descent: acute non-lymphocytic leukaemia (PCIR 1.23; CI (95% 1.02–1.47, Hodgkin's disease (1.34; 1.13–1.59 and Non-Hodgkin/Burkitt lymphoma (1.19; 1.02–1.39. Age, sex, and period of diagnosis showed no influence on the distribution of diagnoses. Conclusion No major differences were found in cancer patterns among cases of Turkish descent compared to all other cases in the GCCR. Slightly higher proportions of systemic malignant diseases indicate that analytical studies involving migrants may help investigating the causes of such cancers.

    Pancreatic cancer (PC) is one of the deadliest cancers worldwide. Surgical resection remains the only curative therapeutic treatment for this disease, although only the minority of patients can be resected due to late diagnosis. Systemic gemcitabine-based chemotherapy plus nab-paclitaxel are used as the gold-standard therapy for patients with advanced PC; although this treatment is associated with a better overall survival compared to the old treatment, many side effects and poor results are still present. Therefore, new alternative therapies have been considered for treatment of advanced PC. Several preclinical studies have demonstrated that curcumin, a naturally occurring polyphenolic compound, has anticancer effects against different types of cancer, including PC, by modulating many molecular targets. Regarding PC, in vitro studies have shown potent cytotoxic effects of curcumin on different PC cell lines including MiaPaCa-2, Panc-1, AsPC-1, and BxPC-3. In addition, in vivo studies on PC models have shown that the anti-proliferative effects of curcumin are caused by the inhibition of oxidative stress and angiogenesis and are due to the induction of apoptosis. On the basis of these results, several researchers tested the anticancer effects of curcumin in clinical trials, trying to overcome the poor bioavailability of this agent by developing new bioavailable forms of curcumin. In this article, we review the results of pre-clinical and clinical studies on the effects of curcumin in the treatment of PC. PMID:27438851

    Full Text Available Orientation: Traditionalists view group interventions from three perspectives: singletons, dyads and whole groups. The focus of this research was on interventions from the third perspective, that of the whole group, using a systems psychodynamic stance. Research purpose: The purpose of the research was to use group-as-a-whole to study individual behaviour in organisations.Motivation for the study: Team research and practice is not on a par with the complexities that teams actually experience. Traditional group interventions use humanistic and functionalistic paradigms that do not consider the unconscious functioning of groups. Interventions that use the system psychodynamic paradigm could address these dynamics because they study behaviour of individual group members in the context of the group-as-a-whole. Research design, approach and method: The researcher conducted action research in a publishing company. He used purposive sampling and analysed the data using qualitative content analysis.Main findings: The researcher found that the group-as-a-whole partly explains the behaviour of team members and that intervening from this perspective could improve negative relationships.Practical/managerial implications: Managers can use interventions that use the groupas- a-whole concept as a diagnostic intervention to study and possibly change the complex behavioural issues that team members experience.Contribution/value-add: The findings give one an understanding of the behaviour of individual group members when one views it from a systems psychodynamic stance. Furthermore, the researcher proposes a group diagnostic intervention that will allow some of the root causes of poor interpersonal behaviour to surface and group members to diagnose and take ownership of their own behaviour.

    Group-theoretical methods have been accepted as exact and reliable tools in studying the physical properties of crystals and quasicrystalline materials. By group representation theory, the maximum number of non-vanishing and independent second- order piezoelectric coefficients required by the seven pentagonal and two icosahedral point groups - that describe the quasicrystal symmetry groups in two and three dimensions - is determined. The schemes of non-vanishing and independent second-order piezoelectric tensor components needed by the nine point groups with five-fold rotations are identified and tabulated employing a compact notation. The results of this group-theoretical study are briefly discussed.

    Mechanisms underlying bone cancer-induced pain are largely unknown. Previous studies indicate that neuroinflammation in the spinal dorsal horn is especially involved. Being first reported as a nonhistone chromosomal protein, high-mobility group box 1 (HMGB1) is now implicated as a mediator of inflammation. We hypothesized that HMGB1 could trigger the release of cytokines in the spinal dorsal horn and contribute to bone cancer pain. To test this hypothesis, we first built a bone cancer pain model induced by intratibal injection of Walker 256 mammary gland carcinoma cells. The structural damage to the tibia was monitored by radiological analysis. The mechanical allodynia was measured and the expression of spinal HMGB1 and IL-1{beta} was evaluated. We observed that inoculation of cancer cells, but not heat-killed cells, induced progressive bone destruction from 9 d to 21 d post inoculation. Behavioral tests demonstrated that the significant nociceptive response in the cancer cells-injected rats emerged on day 9 and this kind of mechanical allodynia lasted at least 21 d following inoculation. Tumor cells inoculation significantly increased HMGB1 expression in the spinal dorsal horn, while intrathecal injecting a neutralizing antibody against HMGB1 showed an effective and reliable anti-allodynia effect with a dose-dependent manner. IL-1{beta} was significantly increased in caner pain rats while intrathecally administration of anti-HMGB1 could decrease IL-1{beta}. Together with previous reports, we predict that bone cancer induces HMGB1 production, enhancing spinal IL-1{beta} expression and thus modulating spinal excitatory synaptic transmission and pain response.

    Background and purpose: This prospective study aimed to assess the profiles of elderly cancer patient to optimize cancer care in Indian setup. The profiles have been compared with that of younger patients in terms of epidemiological, clinical data, co-morbidity, treatment, toxicity, clinical outcome, and survival pattern. Materials and Methods: The study comprised cancer patients attending radiotherapy outdoor (November 2005 to June 2006). There were 104 patients of age ≥60 years (elderly group) and 121 patients of 45-59 years (younger group). Results: Elderly group had median age 65 years (60-88 years) with M:F = 1:1. The younger group had median age 50 years (45-59 years) with M:F = 1:2. Elderly had higher proportion of gastrointestinal and genito-urinary tract malignancies. Younger group had higher proportion of breast, lymphoma, and brain tumor. 13% had co-morbidity, 50% received treatment, 27% were treated with radiotherapy with or without surgery, and two-third of these cases belong to elderly group. Majority tolerated treatment well. 10% had significant grade of toxicity. 57% of elderly patients did not accept and one-fourth of all cases did not complete the prescribed treatment. 88% cases were responders of which 70% showed complete response. There were no differences between two groups. At 12 months 35% of treated patients came for follow-up. At first 12 months, 60-70% were alive without disease. Conclusion: There were differences between two groups in terms of performance status, treatment acceptance, and treatment modality prescribed. Elderly patients deserve same opportunity as younger patients for treatment and survival options from the oncologist. PMID:24455630

    Full Text Available Abstract Background Cancer is mainly a disease of older patients. In older cancer patients, additional endpoints such as quality of survival and daily functioning might be considered equally relevant as overall or disease free survival. However, these factors have been understudied using prospective designs focussing on older cancer patients. Therefore, this study will focus on the impact of cancer, ageing, and their interaction on the long-term wellbeing of older cancer patients. Methods/Design This study is an observational cohort study. We aim to recruit 720 cancer patients above 70 years with a new diagnosis of breast, prostate, lung or gastrointestinal cancer and two control groups: one control group of 720 patients above 70 years without a previous diagnosis of cancer and one control group of 720 cancer patients between 50 - 69 years newly diagnosed with breast, prostate, lung or gastrointestinal cancer. Data collection will take place at inclusion, after six months, after one year and every subsequent year until death or end of the study. Data will be collected through personal interviews (consisting of socio-demographic information, general health information, a comprehensive geriatric assessment, quality of life, health locus of control and a loneliness scale, a handgrip test, assessment of medical records, two buccal swabs and a blood sample from cancer patients (at baseline. As an annex study, caregivers of the participants will be recruited as well. Data collection for caregivers will consist of a self-administered questionnaire examining depression, coping, and burden. Discussion This extensive data collection will increase insight on how wellbeing of older cancer patients is affected by cancer (diagnosis and treatment, ageing, and their interaction. Results may provide new insights, which might contribute to the improvement of care for older cancer patients.

    Purpose: To assess the impact of domicile-based humidification on symptom burden during radiation therapy (RT) for head-and-neck (H and N) cancer. Methods and Materials: From June 2007 through June 2011, 210 patients with H and N cancer receiving RT were randomized to either a control arm or to receive humidification using the Fisher and Paykel Healthcare MR880 humidifier. Humidification commenced on day 1 of RT and continued until Common Terminology Criteria for Adverse Events (CTCAE), version 3.0, clinical mucositis (CMuc) grade ≤1 occurred. Forty-three patients (42%) met a defined benchmark for humidification compliance and contributed to per protocol (PP) analysis. Acute toxicities, hospitalizations, and feeding tube events were recorded prospectively. The McMaster University Head and Neck Radiotherapy Questionnaire (HNRQ) was used for patient-reported outcomes. The primary endpoint was area under the curve (AUC) for CMuc grade ≥2. Results: There were no significant differences in AUC for CMuc ≥2 between the 2 arms. Humidification patients had significantly fewer days in hospital (P=.017). In compliant PP patients, the AUC for CTCAE functional mucositis score (FMuc) ≥2 was significantly reduced (P=.009), and the proportion who never required a feeding tube was significantly greater (P=.04). HNRQ PP analysis estimates also in the direction favoring humidification with less symptom severity, although differences at most time points did not reach significance. Conclusions: TROG 07.03 has provided efficacy signals consistent with a role for humidification in reducing symptom burden from mucositis, but the influence of humidification compliance on the results moderates recommendations regarding its practical utility.

    Asian ethnic subgroups are often treated as a single demographic group in studies looking at cancer screening and health disparities. To evaluate knowledge and health beliefs associated with colorectal cancer (CRC) and CRC screening among Chinese, Korean, and Vietnamese subgroups, a survey assessed participants' demographic characteristics, healthcare utilization, knowledge, beliefs, attitudes associated with CRC and CRC screening. Exploratory factor analysis identified six factors accounting >60 % of the total variance in beliefs and attitudes. Cronbach's alpha coefficients assessed internal consistency. Differences among Asian subgroups were assessed using a Chi square, Fisher's exact, or Kruskal-Wallis test. Pearson's correlation coefficient assessed an association among factors. 654 participants enrolled: 238 Chinese, 217 Korean, and 199 Vietnamese. Statistically significant differences existed in demographic and health care provider characteristics, knowledge, and attitude/belief variables regarding CRC. These included knowledge of CRC screening modalities, reluctance to discuss cancer, belief that cancer is preventable by diet and lifestyle, and intention to undergo CRC screening. Chinese subjects were more likely to use Eastern medicine (52 % Chinese, 25 % Korean, 27 % Vietnamese; p Vietnamese; p Vietnamese subjects were less likely to consider CRC screening (95 % Chinese, 95 % Korean, 80 % Vietnamese; p health beliefs among Asian subgroups. Understanding these differences will enable clinicians to deliver tailored, effective health messages to improve CRC screening and other health behaviors.

    Purpose Epigenetic aberrations have been reported in hepatocellular carcinoma (HCC). In this study of patients with unresectable HCC and chronic liver disease, epigenetic therapy with the histone deacetylase inhibitor belinostat was assessed. The objectives were to determine dose-limiting toxicity and maximum-tolerated dose (MTD), to assess pharmacokinetics in phase I, and to assess activity of and explore potential biomarkers for response in phase II. Patients and Methods Major eligibility criteria included histologically confirmed unresectable HCC, European Cooperative Oncology Group performance score ≤ 2, and adequate organ function. Phase I consisted of 18 patients; belinostat was given intravenously once per day on days 1 to 5 every 3 weeks; dose levels were 600 mg/m2 per day (level 1), 900 mg/m2 per day (level 2), 1,200 mg/m2 per day (level 3), and 1,400 mg/m2 per day (level 4). Phase II consisted of 42 patients. The primary end point was progression-free survival (PFS), and the main secondary end points were response according to Response Evaluation Criteria in Solid Tumors (RECIST) and overall survival (OS). Exploratory analysis was conducted on pretreatment tumor tissues to determine whether HR23B expression is a potential biomarker for response. Results Belinostat pharmacokinetics were linear from 600 to 1,400 mg/m2 without significant accumulation. The MTD was not reached at the maximum dose administered. Dose level 4 was used in phase II. The median number of cycles was two (range, one to 12). The partial response (PR) and stable disease (SD) rates were 2.4% and 45.2%, respectively. The median PFS and OS were 2.64 and 6.60 months, respectively. Exploratory analysis revealed that disease stabilization rate (complete response plus PR plus SD) in tumors having high and low HR23B histoscores were 58% and 14%, respectively (P = .036). Conclusion Epigenetic therapy with belinostat demonstrates tumor stabilization and is generally well-tolerated. HR23B

    Full Text Available Cancer cells try to avoid the overproduction of reactive oxygen species by metabolic rearrangements. These cells also develop specific strategies to increase ROS resistance and to express the enzymatic activities necessary for ROS detoxification. Oxidative stress produces DNA damage and also induces responses, which could help the cell to restore the initial equilibrium. But if this is not possible, oxidative stress finally activates signals that will lead to cell death. High mobility group B (HMGB proteins have been previously related to the onset and progressions of cancers of different origins. The protein HMGB1 behaves as a redox sensor and its structural changes, which are conditioned by the oxidative environment, are associated with different functions of the protein. This review describes recent advances in the role of human HMGB proteins and other proteins interacting with them, in cancerous processes related to oxidative stress, with special reference to ovarian and prostate cancer. Their participation in the molecular mechanisms of resistance to cisplatin, a drug commonly used in chemotherapy, is also revised.

    Background Gastric cancer is one of the most common malignancies, and has a high mortality rate. miR-495 acts as a suppressor in some cancers and HMGA2 (high mobility group AT-hook 2) is a facilitator for cell growth and epithelial-mesenchymal transition (EMT), but little is known about their effect in gastric cancer. This study aimed to investigate the role and mechanism of miR-495 in gastric cancer. Material/Methods miR-495 levels were quantitatively analyzed in gastric cancer tissue and GES-1, SGC-7901, BGC-823, and HGC-27 cell lines by qRT-PCR. Levels of miR-495 and HMGA2 were altered by cell transfection, after which cell migration and invasion were examined by Transwell and E-cadherin (CDH1); vimentin (VIM), and alpha smooth muscle actin (ACTA2) were detected by qRT-PCR and Western blotting. The interaction between miR-495 and HMGA2 was verified by dual-luciferase reporter assay. Results miR-495 was significantly downregulated in cancer tissue and cell lines (pgastric cancer tissue, and promoted cell migration and invasion, inhibited CDH1, and elevated VIM and ACTA2. Conclusions miR-495 acts as a tumor suppressor in gastric cancer by inhibiting cell migration and invasion, which may be associated with its direct inhibition on HMGA2. These results suggest a promising therapeutic strategy for gastric cancer treatment. PMID:28159956

    Full Text Available Introduction: As one of the most common cancers among head and neck malignancies, cancer of the oral cavity probably has some variations in countries with a high prevalence of esophageal cancer.  Materials and Methods: Patients with oral cavity cancer who were treated at two tertiary referral centers from January 1999 to January 2009 were included in this study. In addition to demographic data, information regarding personal and family history of head and neck cancer, use of dentures, presence of immune deficiency, consumption of alcohol, and incidence of cigarette smoking was collected. Additionally, a history of opium usage was obtained from the participants in this study. Moreover, an appropriately matched control group was selected for comparisons between the risk factors.   Results: A total of 557 patients were entered into this study over a 10-year period, of whom 219 (39.3% were female and the remaining 338 (60.7% were male. The tongue was the most common site of cancer and 9% of the patients had a history of opium abuse, but more than half of the patients did not have any recognized risk factors. The incidence and stage of cancer had a significant relationship with cigarette smoking (P= 0.013.   Conclusion: Tongue cancer in non-smokers is the predominant pattern of oral cavity cancer in Iran.

  6. Carbohydrate Microarrays Identify Blood Group Precursor Cryptic Epitopes as Potential Immunological Targets of Breast Cancer

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Using carbohydrate microarrays, we explored potential natural ligands of antitumor monoclonal antibody HAE3. This antibody was raised against a murine mammary tumor antigen but was found to cross-react with a number of human epithelial tumors in tissues. Our carbohydrate microarray analysis reveals that HAE3 is specific for an O-glycan cryptic epitope that is normally hidden in the cores of blood group substances. Using HAE3 to screen tumor cell surface markers by flow cytometry, we found that the HAE3 glycoepitope, gpHAE3, was highly expressed by a number of human breast cancer cell lines, including some triple-negative cancers that lack the estrogen, progesterone, and Her2/neu receptors. Taken together, we demonstrate that HAE3 recognizes a conserved cryptic glycoepitope of blood group precursors, which is nevertheless selectively expressed and surface-exposed in certain breast tumor cells. The potential of this class of O-glycan cryptic antigens in breast cancer subtyping and targeted immunotherapy warrants further investigation.

    Initially, Gastrointestinal Study Group in Japan Clinical Oncology Group (GIOSG/JCOG) focused on gastric cancer. In 1980s, fluoropyrimidine, cisplatin and mitomycin C were key drugs. A randomized Phase II trial (JCOG8501) comparing futrafur plus mitomycin C and uracil plus futrafur and mitomycin C showed a higher response rate of uracil plus futrafur and mitomycin C than futrafur plus mitomycin C. From the results of two Phase II trials of etoposide, adriamycin and cisplatin, and cisplatin plus 5-fluorouracil, uracil plus futrafur and mitomycin C and cisplatin plus 5-fluorouracil were adopted for the test arms of the Phase III trial (JCOG9205) comparing with continuous infusion of 5-fluorouracil as a control arm. Neither cisplatin plus 5-fluorouracil nor uracil plus futrafur and mitomycin C showed a survival benefit over continuous infusion of 5-fluorouracil. In late 1990s, new agents, irinotecan and S-1, were developed for gastric cancer in Japan. GIOSG conducted a Phase III trial (JCOG9912) investigating superiority of irinotecan plus cisplatin and non-inferiority of monotherapy with S-1 compared with continuous infusion of 5-fluorouracil, and S-1 succeeded in showing non-inferiority. Then, SPIRITS trial showed a survival benefit of S-1 plus cisplatin over S-1, resulting in the establishment of a standard care for advanced gastric cancer in Japan. GIOSG have merged with Gastric Cancer Study Group as the Stomach Cancer Study Group (SCSG) from 2011. Recent progress in the development of new drugs has been remarkable. From the point of the roles shared with many other study groups for clinical trials, including registration trials of new drugs conducted by pharmaceutical companies, SCSG should recognize its role and conduct clinical trials with high quality for establishing new standard treatment.

    ICON3 trial results have suggested that CAP and carboplatin-taxol regimens as first-line treatment of advanced ovarian cancer (AOC) yield similar survival. We explored the impact of increased dose of cyclophosphamide in a modified CAP regimen on the disease-free survival (DFS) and overall survival (OS) of AOC patients. From February 1994 to June 1997, 164 patients were randomised to receive six cycles every 3 weeks of either standard CEP (S) combining cyclophosphamide (C), 500 mg m(-2), epirubicin (E) 50 mg m(-2), and cisplatin (P) 75 mg m(-2) or intensive CEP (I) with E and P at the same doses, but with (C) 1800 mg m(-2) and filgrastim 5 mug kg(-1) per day x 10 days. Response was evaluated at second-look surgery. Patient characteristics were well balanced. Except for grade 3-4 neutropaenia (S: 54%, I: 38% of cycles), Arm1 presented a significantly more important toxicity: infection requiring antibiotics, grade 3-4 thrombocytopaenia, anaemia, nausea-vomiting, diarrhoea, mucositis. Median follow-up was 84 months. DFS (15.9 vs 14.8 months) and OS (33 vs 30 months) were not significantly different between S and I (P>0.05). Increasing cyclophosphamide dose by more than 3 times with filgrastim support in the modified CAP regimen CEP induces more toxicity but not better efficacy in AOC.

    Gastric cancer is a complex, heterogeneous, and multistep disease. Over the past decades, several studies have aimed to determine the molecular factors that lead to gastric cancer development and progression. After completing the human genome sequencing, proteomic technologies have presented rapid progress. Differently from the relative static state of genome, the cell proteome is dynamic and changes in pathologic conditions. Proteomic approaches have been used to determine proteome profiles and identify differentially expressed proteins between groups of samples, such as neoplastic and nonneoplastic samples or between samples of different cancer subtypes or stages. Therefore, proteomic technologies are a useful tool toward improving the knowledge of gastric cancer molecular pathogenesis and the understanding of tumor heterogeneity. This review aimed to summarize the proteins or protein families that are frequently identified by using high-throughput screening methods and which thus may have a key role in gastric carcinogenesis. The increased knowledge of gastric carcinogenesis will clearly help in the development of new anticancer treatments. Although the studies are still in their infancy, the reviewed proteins may be useful for gastric cancer diagnosis, prognosis, and patient management.

  11. Speaking up in groups: a cross-level study of group voice climate and voice.

    Despite a growing body of research on employee voice—defined as the discretionary communication of ideas, suggestions, or opinions intended to improve organizational or unit functioning—the effects of shared or collective-level cognitions have received scant attention. There has also been relatively little research on voice within work groups. Our goal in this study was to address these important gaps by focusing on the effects of group-level beliefs about voice (i.e., group voice climate) on individual voice behavior within work groups. We conducted a cross-level investigation of voice behavior within 42 groups of engineers from a large chemical company. Consistent with our hypotheses, group voice climate was highly predictive of voice and explained variance beyond the effects of individual-level identification and satisfaction, and procedural justice climate. Also consistent with predictions, the effect of identification on voice was stronger in groups with favorable voice climates. These findings provide evidence that voice is shaped not just by individual attitudes and perceptions of the work context, as past research has shown, but also by group-level beliefs. The results also highlight the importance of broadening our conceptual models of voice to include shared cognitions and of conducting additional cross-level research on voice.

    A wide variety of occupations has been associated with prostate cancer in previous retrospective studies. Most attention has been paid to farming, metal working, and the rubber industry. Today, these results cannot be affirmed with confidence, because many associations could be influenced by recall bias, have been inconsistent, or have not been confirmed satisfactory in subsequent studies. This study was conducted to investigate and confirm these important associations in a large prospective cohort study. The authors conducted a prospective cohort study among 58,279 men. In September 1986, the cohort members (55-69 years) completed a self-administered questionnaire on potential cancer risk factors, including job history. Related job codes were clustered in professional groups. These predefined clusters were investigated in 3 time windows: 1) profession ever performed, 2) longest profession ever held, and 3) last profession held at baseline. Follow up for incident prostate cancer was established by linkage to cancer registries until December 1993. A case-cohort approach was used based on 830 cases and 1525 subcohort members. To minimize false-positive results, 99% confidence intervals (99% CI) were calculated. Although moderately decreased prostate cancer risks were found for electricians, farmers, firefighters, woodworkers, textile workers, butchers, salesmen, teachers, and clerical workers, none of the relative risks (RR) were found to be statistically significant. For road transporters, metal workers, and managers, no association with prostate cancer risk was found. Although the RR for railway workers, mechanics, welders, chemists, painters, and cooks was moderately increased, these estimates were not statistically significant. For men who reported to have ever worked in the rubber industry, we found a substantially increased prostate cancer risk, but not statistically significant (RR, 4.18; 99% CI = 0.22-80.45). For policemen, we found a substantial and

    The International Agency for Research on Cancer estimates that over half of the new cancer cases and almost two-thirds of the cancer deaths in 2012 occurred in low and middle income countries. To discuss the challenges and opportunities to reducing the burden of cancer worldwide, the Molecular Epidemiology and the Environment and the International Issues in Cancer Special Interest Groups joined forces to hold a session during the 38th Annual Meeting of the American Society of Preventive Oncology (March 2014, Arlington, Virginia). The session highlighted three topics of particular interest to molecular cancer prevention researchers working internationally, specifically: 1) biomarkers in cancer research; 2) environmental exposures and cancer; and 3) molecular pathological epidemiology. A major factor for successful collaboration illuminated during the discussion was the need for strong, committed, and reliable international partners. A key element of establishing such relationships is to thoroughly involve individual international collaborators in the development of the research question; engaged international collaborators are particularly motivated to champion and shepherd the project through all necessary steps, including issues relating to institutional review boards, political sensitivity, laboratory-based assays, and tumor subtyping. Also essential is allotting time for the building, maintaining, and investing in such relationships so that successful international collaborations may take root and bloom. While there are many challenges inherent to international molecular cancer research, the opportunities for furthering the science and prevention of cancer worldwide are great, particularly at this time of increasing cancer incidence and prevalence in low and middle income countries.

    Purpose: To evaluate the therapeutic efficacy of 3-month triplet induction chemotherapy (ICT) followed by concomitant chemoradiotherapy (CCRT) in patients with locally advanced pancreatic cancer (LAPC). Patients and Methods: Chemonaieve patients with measurable, histologically confirmed LAPC were eligible. The ICT consisted of biweekly gemcitabine (800 mg/m{sup 2}) infusion at a fixed dose rate (10 mg/m{sup 2}/min), followed by 85 mg/m{sup 2} oxaliplatin and 48-h infusion of 5-fluorouracil/leucovorin (3000/150 mg/m{sup 2}) for 6 cycles. Patients without disease progression 4 weeks after ICT would receive weekly 400 mg/m{sup 2} gemcitabine and 5040 cGy radiation in 28 fractions. After CCRT, patients were subjected for surgical intervention and/or maintenance chemotherapy until progression or intolerable toxicity. Results: Between December 2004 and August 2008, 50 patients were enrolled. The best responses after ICT were partial response (PR) in 9, stable disease in 26, and progressive disease or not evaluable in 15. Among the former 35 patients, 2 had disease progression before CCRT, and 3 declined to have CCRT. Of the 30 patients receiving CCRT, an additional 4 and 1 patient(s) achieved PR at the end of CCRT and during maintenance chemotherapy, respectively. On intent-to-treat analysis, the overall best response was PR in 14 patients and stable disease in 21. The overall response rate and disease control rate were 28% (95% confidence interval [CI], 16.2-42.5%) and 70% (95% CI, 44.4-99.2%), respectively. The median time to progression and overall survival of the intent-to-treat population was 9.3 (95% CI, 5.8-12.8) months and 14.5 (95% CI, 11.9-17.1) months, respectively. One- and two-year survival rates were 68% (95% CI, 55.1-80.9%) and 20.6% (95% CI, 8.7-32.5%), respectively. Neutropenia was the most common Grade 3-4 toxicity of both ICT and CCRT, with a frequency of 28% and 26.7%, respectively. Significant sensory neuropathy occurred in 9 patients (18

  18. Differential epigenetic regulation of TOX subfamily high mobility group box genes in lung and breast cancers.

    Directory of Open Access Journals (Sweden)

    Mathewos Tessema

    Full Text Available Aberrant cytosine methylation affects regulation of hundreds of genes during cancer development. In this study, a novel aberrantly hypermethylated CpG island in cancer was discovered within the TOX2 promoter. TOX2 was unmethylated in normal cells but 28% lung (n = 190 and 23% breast (n = 80 tumors were methylated. Expression of two novel TOX2 transcripts identified was significantly reduced in primary lung tumors than distant normal lung (p<0.05. These transcripts were silenced in methylated lung and breast cancer cells and 5-Aza-2-deoxycytidine treatment re-expressed both. Extension of these assays to TOX, TOX3, and TOX4 genes that share similar genomic structure and protein homology with TOX2 revealed distinct methylation profiles by smoking status, histology, and cancer type. TOX was almost exclusively methylated in breast (43% than lung (5% cancer, whereas TOX3 was frequently methylated in lung (58% than breast (30% tumors. TOX4 was unmethylated in all samples and showed the highest expression in normal lung. Compared to TOX4, expression of TOX, TOX2 and TOX3 in normal lung was 25, 44, and 88% lower, respectively, supporting the premise that reduced promoter activity confers increased susceptibility to methylation during lung carcinogenesis. Genome-wide assays revealed that siRNA-mediated TOX2 knockdown modulated multiple pathways while TOX3 inactivation targeted neuronal development and function. Although these knockdowns did not result in further phenotypic changes of lung cancer cells in vitro, the impact on tissue remodeling, inflammatory response, and cell differentiation pathways suggest a potential role for TOX2 in modulating tumor microenvironment.

    Background: This study investigated patients' understanding of the role of music in coping and in influencing their well-being. Methods: A qualitative study was conducted based on semi-structured interviews with 17 cancer patients. Participants were chosen from a group of patients who had listened to or played music as a means of coping with their illness. Results: The study shows the importance of considering the roles that different kinds of music play in coping with cancer. The music of nature, healing music, religious music and cheerful music each have different benefits for patients. Conclusions: A patient's situation and his or her individual characteristics determine the types of music that can act as a useful or harmful coping strategy. Therefore, it is essential to investigate the types of individual characteristics that can make listening to different kinds of music a helpful or harmful coping method.

    Full text: The use of Raman scattering to differentiate the biochemistry and hence distinguish between normal and abnormal samples of breast cancer with induced stress was investigated. Twelve different rat serum samples (5 control samples and 7 breast cancer samples) were measured. 25 spectra per sample were acquired in a region of 50 X 50 microns. Three hundred spectra were recorded and the spectral diagnostic models were constructed by using multivariate statistical analysis on the spectral matrix to carry out the discrimination between the control samples and cancers samples with induced stress. The spectral recording was performed with Raman microscopy system Thermo Scientific XRD in the range from 200 to 2000 cm{sup -1} with a laser source of 780 nm, 24 m W of power and 50 s and exposure time were used for each spectrum. It is shown that the serum samples from rats with breast cancer and the control group can be discriminate when the multivariate analysis methods are applied to their Raman data set. The ratios were significant and correspond to proteins and phospholipids. The preliminary results suggest that the Raman spectroscopy could be an alternative technique to study the breast cancer in humans in a near future. (Author)

    AIM: To evaluate the preliminary effects of comprehensive prevention of gastric cancer in Zhuanghe County epidemiologically.METHODS: Stratified sampling and cluster sampling were applied to define the intervention group and the control group. The prospective cohort study was used for evaluating the effect of preventing gastric cancer. The relative risk (RR)and attributable risk percent (AR %) of intervention on gastric cancer death were calculated. Potential years of life lost (PLYY) of the disease was analyzed, and the RR and AR %of PYLL were calculated. Survival analysis was applied among the screened patients.RESULTS: In the first 4 years after intervening, the relative risk (RR) of intervention on death was 0.5059 (95 % CI:0.3462~0.7392,P<0.05) with significance statistically. AR %of the intervention on death was 49.41%. The RR of intervention on cumulative PYLL was 0.6778 (95 % CI:0.5604~0.8198,P<0.05) with statistic significance. AR %of the intervention on cumulative PYLL was 30.32 %. The four-year survival rate of the screened patients was 0.6751(95 % CI: 0.5298~0.9047).CONCLUSION: The initiative intervention results showed that the intervention approach used in the trial was effective, it reduced mortality and increased survival rate, and alleviated the adverse effect of gastric cancer on the health and life of screened population.

    2014-01-01

    In recent years, a rapidly increasing number of studies have investigated the relationship of vitamin D with total cancer and site-specific cancer obtaining diverse findings. In this chapter we provide an overview of epidemiological studies of vitamin D intake, 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D serum levels and vitamin D associated polymorphisms in relation to total and site-specific cancer risk. Overall, epidemiological evidence for total cancer is inconclusive. However, a large number of studies support a relationship of vitamin D with colorectal cancer and to a lesser extent with breast cancer. Findings are inconsistent for other cancers including all other gastrointestinal cancers and prostate cancer. Different vitamin D associated polymorphisms were found to be significantly associated to colorectal, breast and prostate cancer risk.

    Purpose: To evaluate effects of radiation therapy, chemotherapy, cigarette smoking, and alcohol consumption on the risk of second primary salivary gland cancer (SGC) in the Childhood Cancer Survivor Study (CCSS). Methods and Materials: Standardized incidence ratios (SIR) and excess absolute risks (EAR) of SGC in the CCSS were calculated using incidence rates from Surveillance, Epidemiology, and End Results population-based cancer registries. Radiation dose to the salivary glands was estimated based on medical records. Poisson regression was used to assess risks with respect to radiation dose, chemotherapy, smoking, and alcohol consumption. Results: During the time period of the study, 23 cases of SGC were diagnosed among 14,135 childhood cancer survivors. The mean age at diagnosis of the first primary cancer was 8.3 years, and the mean age at SGC diagnosis was 24.8 years. The incidence of SGC was 39-fold higher in the cohort than in the general population (SIR = 39.4; 95% CI = 25.4-57.8). The EAR was 9.8 per 100,000 person-years. Risk increased linearly with radiation dose (excess relative risk = 0.36/Gy; 95% CI = 0.06-2.5) and remained elevated after 20 years. There was no significant trend of increasing risk with increasing dose of chemotherapeutic agents, pack-years of cigarette smoking, or alcohol intake. Conclusion: Although the cumulative incidence of SGC was low, childhood cancer survivors treated with radiation experienced significantly increased risk for at least 2 decades after exposure, and risk was positively associated with radiation dose. Results underscore the importance of long-term follow up of childhood cancer survivors for the development of new malignancies.

    Full Text Available BACKGROUND AND AIMS The “fallopian tubes” (oviducts or uterine tubes are long paired flexuous reproductive organ which transports ova, spermatozoa, zygotes, the pre-implantation morulae and blastocyst. It has major role during reproductive period, but it remains as if vestigial organ before puberty and after menopause. Due to increasing rate of tubal block and infertility, oviducts and their structures gaining importance and have become a subject of research in present days particularly epithelium. The aim of the study is to ascertain any histological difference of tubal epithelium in different age groups and the research work could be utilized for investigation and management of infertility. MATERIALS AND METHODS Seven samples of each group i.e., prereproductive, reproductive & postmenopausal were collected from fresh unembalmed human cadavers received in the department of Anatomy, FAA Medical College, Barpeta, Assam. The slides were prepared using the standard laboratory procedure. Under low and high power objectives the type of cells were observed and epithelial height was measured in the different segments. Stress was given for any significant difference of epithelial height between the different age groups. RESULTS Study revealed that among the groups within the same segment, epithelial height was recorded highest (33.57µm in reproductive group as against the lowest (22.91µm in post-menopausal group. Epithelial structures of the prereproductive and reproductive groups were significantly differed (p<0.01 from the postmenopausal group. CONCLUSIONS From the findings of the present study it can be concluded that: 1. In all the groups fallopian tubal epithelium is of simple columnar type and contains three types of cells. Cells are ciliated, secretory & peg (intercalary cells. 2. In all the groups same type of increasing trend of epithelial height from intramural segment to ampullary segment was recorded. 3. In intergroup comparison of

    Religious group identification is an important but understudied social identity. The present study investigates religious group identification among adolescents of different faiths (Hindu, Muslim, Christian) living in multicultural Mauritius. It further explores how religious and national group identities come together among religious majority and minority adolescents. For three age groups (11 to 19 years, N = 2152) we examined the strength of adolescents' religious and national group identification, the associations between these two identities, and the relationships to global self-esteem. Across age and religious group, participants reported stronger identification with their religious group than with the nation. Identification with both categories declined with age, with the exception of Muslims, whose strong religious identification was found across adolescence. The association between religious and national identification was positive, albeit stronger for the majority group of Hindus and for early adolescents. We examined the manner in which religious and national identities come together using a direct self-identification measure and by combining the separate continuous measures of identification. Four distinct clusters of identification (predominant religious identifiers, dual identifiers, neutrals, and separate individuals) that were differently associated with global self-esteem were found. Dual identifiers reported the highest level of global self-esteem. The clusters of identification did not fully correspond to the findings for the direct self-identification measure. The results are discussed in terms of the meaning of dual identity and the positive manner in which adolescents can manage their multiple identities while taking into account the ideological framework in which those identities are played out.

    The occurrence of cancer and neurological disorders in first- and second-degree relatives of children in the United States and Canada diagnosed with brain tumor before age six was investigated. A pair-matched case-control study with 155 astrocytoma and 166 primitive neuroectodermal tumor (PNET) cases was performed. Cases were identified through the Childrens Cancer Group. Controls were selected by random-digit dialing and matched to cases on age, race, and telephone area code and exchange. Childhood cancers were more common in PNET relatives compared with the general population (standardized incidence ratio [SIR] = 2.5, 95 percent confidence interval [CI] 1.1-4.8, P = 0.02) and with control relatives (odds ratio [OR] = 3.0, CI = 0.5-30, P = 0.29). For astrocytoma, nonsignificant excesses of brain tumor, leukemia/lymphoma, and childhood cancer occurred among case relatives compared with control relatives, but not compared with the general population. Astrocytoma cases were significantly more likely than controls to have a relative with seizures (OR = 2.5, CI = 1.2-4.9, P = 0.009), especially childhood seizures (OR = 3.4, CI = 1.2-12, P = 0.02), epilepsy (OR = 3.0, CI = 0.9-13, P = 0.08), and febrile convulsions (OR = 4.5, CI = 0.9-43, P = 0.07). A family history of stroke was not a risk factor for either type of brain tumor. These results suggest that some childhood brain tumors may result from a genetic susceptibility and that some risk factors may affect childhood astrocytoma and PNET differently.

    A domestic multicenter phase I study of stereotactic body radiotherapy (SBRT) for T2N0M0 non-small cell lung cancer in inoperable patients or elderly patients who refused surgery was initiated as the Japan Clinical Oncology Group trial (JCOG0702) in Japan. Prior to the clinical study, the accuracy of dose calculation in radiation treatment-planning systems was surveyed in participating institutions, and differences in the irradiating dose between the institutions were investigated. We developed a water tank-type lung phantom appropriate for verification of the exposure dose in lung SBRT. Using this water tank-type lung phantom, the dose calculated in the radiation treatment-planning system and the measured dose using a free air ionization chamber and dosimetric film were compared in a visiting survey of the seven institutions participating in the clinical study. In all participating institutions, differences between the calculated and the measured dose in the irradiation plan were as follows: the accuracy of the absolute dose in the center of the simulated tumor measured using a free air ionization chamber was within 2%, the mean gamma value was ≤ 0.47 on gamma analysis following the local dose criteria, and the pass rate was >87% for 3%/3 mm from measurement of dose distribution with dosimetric film. These findings confirmed the accuracy of delivery doses in the institutions participating in the clinical study, so that a study with integration of the institutions could be initiated.

    The cancer patients who received chemotherapy, radiotherapy, hematopoietic stem cell transplant and terminal care often have a wide range of stomatitis, which induces severe pain and limits fundamental life behaviors such as "eating, drinking and talking". In addition, oral mucositis frequently leads to systemic infection through opportunistic microorganisms, which causes extension of hospitalization. Severe oral mucositis often causes cancer patients to partially or completely discontinue/modify cancer therapy regimen, which adversely affects the curative effects of cancer. Therefore, the control of oral mucositis is important and indispensable for improvement of quality of life and prognosis. In this review, we introduce recent trends of the oral mucositis management in cancer patients, according to the following sentences; 1) pathophysiological mechanisms of oral mucositis, 2) assessment, 3) risk factors, 4) prevention and treatment, and 5) development of novel therapy for oral mucositis.

    One of Bion's least-acknowledged contributions to psychoanalytic theory is his study of the relationship between the mind of the individual (the ability to think), the mentalities of groups of which the individual is a member, and the individual's bodily states. Bion's early work on group therapy evolved into a study of the interplay between mind and bodily instincts associated with being a member of a group, and became the impetus for his theory of thinking. On the foundation of Bion's ideas concerning this interaction among the thinking of the individual, group mentality, and the psyche-soma, the author presents his thoughts on the ways in which group mentality is recognizable in the analysis of individuals.

    Aberrant activation of the nuclear factor kappa B (NFkB) transcription system contributes to cancer progression, and has a harmful effect on bone health. Several major components of the NFkB pathway such as IkB Kinase (IKK) and the NFkB subunits contain cysteine residues that are critical for their activity. The interaction of electrophiles with these cysteine residues results in NFkB inhibition. Carotenoids, hydrophobic plant pigments, are devoid of electrophilic groups, and we have previously demonstrated that carotenoid derivatives, but not the native compounds activate the Nrf2 transcription system. The aim of the current study was to examine whether carotenoid derivatives inhibit NFkB, and, if so, to determine the molecular mechanism underpinning the inhibitory action. We report in the present study that a mixture of oxidized derivatives, prepared by ethanol extraction from partially oxidized lycopene preparation, inhibited NFkB reporter gene activity. In contrast, the intact carotenoid was inactive. A series of synthetic dialdehyde carotenoid derivatives inhibited reporter activity as well as several stages of the NFkB pathway in both cancer and bone cells. The activity of the carotenoid derivatives depended on the reactivity of the electrophilic groups in reactions such as Michael addition to sulfhydryl groups of proteins. Specifically, carotenoid derivatives directly interacted with two key proteins of the NFkB pathway: the IKKβ and the p65 subunit. Direct interaction with IKKβ was found in an in vitro kinase assay with a recombinant enzyme. The inhibition by carotenoid derivatives of p65 transcriptional activity was observed in a reporter gene assay performed in the presence of excess p65. This inhibition action resulted, at least in part, from direct interaction of the carotenoid derivative with p65 leading to reduced binding of the protein to DNA as evidenced by electrophoretic mobility shift assay (EMSA) experiments. Importantly, we found by using

    Cancer is a potential life-threatening illness that engenders considerable psychologic distress, requiring persistent coping for the treatment procedures. In this cross-sectional descriptive study stress levels and coping strategies of 257 cancer patients residing in South Korea are addressed. Lazarus and Folkman's theory of stress and coping was used as the theoretical framework. The data were collected from November 1999 to March 2000 by face-to-face interviews. Study participants were primarily male (62.6%) and married (91.4%). Cancer of the gastrointestinal system was the most prevalent type of cancer (31.3%). Women and the patients in the third-stage of cancer showed higher stress but less coping than other groups. Stress was negatively correlated with both problem-focused coping and emotion-focused coping. Korean patients with cancer used emotion-focused coping strategies more than problem-focused coping strategies.

    In 1994, the International Agency for Research on Cancer (IARC) classified wood duct as a human carcinogen, based on very strong evidence of a carcinogenic risk of sino-nasal cancer. Excesses of other cancers, including lung and stomach, have been reported among persons employed in wood industries or occupationally exposed to wood dust, but not as consistently. We investigated such possible associations using the mortality experience of 362,823 men enrolled in the American Cancer Society's Cancer Prevention Study-II in 1982 and followed up for 6 years. Within this group, 45,399 men (12.5%) reported either employment in a wood-related occupation or exposure to wood dust or both. Among woodworkers, a small but significant excess risk was found for all cases of death (RR 1.17 (95% CI 1.11-1.24)) and for total malignancies (RR 1.17 (1.05-1.30)). Among men who reported exposure to wood dust, there was an elevated risk of total mortality (Rr 1.07 (1.03-1.11)), total malignancies (RR 1.08 (1.01-1.15)), and lung cancer (RR 1.17 (1.04-1.31)). Among woodworkers, a significant trend (P = 0.02) of increasing risk of lung cancer with increasing duration of exposure was observed. An unexpected, significantly increased mortality from prostate cancer was observed in both wood-employed and wood-exposed, and a twofold increased risk of fatal brain cancer was seen among the former. Lung cancer mortality was especially high among woodworkers who also reported exposure to asbestos or formaldehyde, and it appears that exposure to these known carcinogens may partly explain the observed increased risks. Excess sino-nasal cancer was not observed, but the number of cases was small.

    Full Text Available Asparouhov and Muthen (forthcoming presented a new method for multiple-group confirmatory factor analysis (CFA, referred to as the alignment method. The alignment method can be used to estimate group-specific factor means and variances without requiring exact measurement invariance. A strength of the method is the ability to conveniently estimate models for many groups, such as with comparisons of countries. This paper focuses on IRT applications of the alignment method. An empirical investigation is made of binary knowledge items administered in two separate surveys of a set of countries. A Monte Carlo study is presented that shows how the quality of the alignment can be assessed.

    Lung cancer patients experience loss of physical capacity, dyspnea, pain, reduced energy and psychological distress. The aim of this study was to explore feasibility, health benefits and barriers of exercise in former sedentary patients with advanced stage lung cancer, non-small cell lung cancer (NSCLC) (III-IV) and small cell lung cancer (SCLC) (ED), undergoing chemotherapy. The intervention consisted of a hospital-based, supervised, group exercise and relaxation program comprising resistance-, cardiovascular- and relaxation training 4 h weekly, 6 weeks, and a concurrent unsupervised home-based exercise program. An explorative study using individual semi-structured interviews (n=15) and one focus group interview (n=8) was conducted among the participants. Throughout the intervention the patients experienced increased muscle strength, improvement in wellbeing, breathlessness and energy. The group exercise and relaxation intervention showed an adherence rate of 76%, whereas the patients failed to comply with the home-based exercise. The hospital-based intervention initiated at time of diagnosis encouraged former sedentary lung cancer patients to participation and was undertaken safely by cancer patients with advanced stages of disease, during treatment. The patients experienced physical, functional and emotional benefits. This study confirmed that supervised training in peer-groups was beneficial, even in a cancer population with full-blown symptom burden and poor prognosis.

    As there is a risk for relapse in early breast cancer, especially at 1-3 years post surgery, the need for adjuvant therapy is clear. In terms of disease-free survival, aromatase inhibitors have emerged as superior to tamoxifen for the adjuvant treatment of hormone-sensitive breast cancer in several Phase III clinical trials. Of these trials, the Breast International Group (BIG) 1-98 trial stands out as unique in design, as it is the only trial to address whether an aromatase inhibitor is more effective as initial adjuvant therapy or as sequential therapy with an aromatase inhibitor and tamoxifen in either order and in rigor of end points and safety evaluations. When compared with tamoxifen, letrozole has been shown to significantly reduce recurrence risk in the overall population by 19% and also significantly reduced recurrence risk in the patient subgroups at increased risk: node-positive and previously chemotherapy-treated patients. Letrozole is the only aromatase inhibitor to demonstrate a significant 27% reduction in the risk of distant metastases (p = 0.001) in the clinically relevant, hormone receptor-positive population in the initial adjuvant setting. Recent results also suggest that letrozole in particular reduces the risk of distant metastases early on after initial surgery for breast cancer. This is important, as early distant metastatic events compose the majority of early recurrences and are a well-recognized predictor of breast cancer death. Letrozole has been found to be well tolerated in the initial adjuvant treatment setting, and these data have been confirmed by long-term safety data from the monotherapy analysis in the BIG 1-98 study. Thus far, the results from the BIG 1-98 trial provide clear support for the use of letrozole in the initial adjuvant treatment of breast cancer. Future studies will provide the definitive answer to questions of which initial adjuvant therapy is superior (i.e., anastrozole or letrozole) and information as to the

    Full Text Available Poor prognosis for late-stage, high-grade, and recurrent cancers has been motivating cancer researchers to search for more efficient biomarkers to identify the onset of cancer. Recent advances in constructing and dynamically analyzing biomolecular networks for different types of cancer have provided a promising novel strategy to detect tumorigenesis and metastasis. The observation of different biomolecular networks associated with normal and cancerous states led us to hypothesize that correlations for gene expressions could serve as valid indicators of early cancer development. In this pilot study, we tested our hypothesis by examining whether the mRNA expressions of three randomly selected cancer-related genes PIK3C3, PIM3, and PTEN were correlated during cancer progression and the correlation coefficients could be used for cancer diagnosis. Strong correlations (0.68≤r≤1.0 were observed between PIK3C3 and PIM3 in breast cancer, between PIK3C3 and PTEN in breast and ovary cancers, and between PIM3 and PTEN in breast, kidney, liver, and thyroid cancers during disease progression, implicating that the correlations for cancer network gene expressions could serve as a supplement to current clinical biomarkers, such as cancer antigens, for early cancer diagnosis.

    Full Text Available Background: Triple negative breast cancers (TNBC are defined by absence of estrogen and progesterone receptors (ER and PR and absence of overexpression of human epidermal growth factor receptor 2 (Her2. They are associated with poor prognosis. The purpose of this study is to study the clinicopathologic parameters of TNBC such as age, tumor size, stage, grade, and lymph node involvement and compare them with nonTNBC tumors. There are many studies which have shown that TNBC are similar to basal-like breast cancers (BBC. We have found the proportion of BBC in the TNBC group using surrogate immunohistochemical (IHC markers cytokeratin5 (CK5 and epidermal growth factor receptor (EGFR. Materials and Methods : This is a retrospective study of 102 cases of carcinoma breast. Clinical records of the cases were retrieved. Histopathology slides and the IHC slides (ER, PR, Her2 were reviewed. Thus, two groups of patients were made TNBC and nonTNBC. Using the software SPSS version 16 statistical significance of the difference between clinicopathologic variables of the two groups was calculated. TNBC group was later studied for the presence of basal markers CK5 and EGFR using tissue microarray. Results: Statistically significant difference was found between the two groups in the variables such as mean age at diagnosis, mean tumor size, tumor grade, and the presence of lymphovascular invasion. Conclusions: TNBC formed 23.5% of total cases. Overall, TNBC were high grade tumors with larger size at diagnosis, presenting in younger women and showing lymphovascular invasion in a higher number of cases. 87.5% of TNBC were BBC.

    Shanghai is the largest industrial centre in China and has a history of about 50 years in producing and applying benzidine derived dyes. A series of epidemiological studies on the carcinogenicity of benzidine and its derived dyes have been performed since 1979. This report describes three such studies. A case-control study was carried out on 344 cases of bladder cancer, each matched for age and sex, with a person without bladder cancer. Factors studied were occupational exposure, smoking, drinking, medical histories, and family history of bladder cancer and other carcinomas. The correlation between bladder cancer and occupational exposures (relative risk (RR) 5.71) was greater than that between bladder cancer and smoking (RR 1.53). A retrospective cohort study was conducted in seven dyestuffs factories where benzidine had served as an intermediate in the manufacture of dyes before 1976. The cohort was made up of 550 men and 186 women. The men were divided into two groups according to job; 354 were assigned to a presynthesis group and 196 to a postsynthesis group. Those in the presynthesis group were thought to have been exposed to benzidine and the subjects in the postsynthesis group were exposed mainly to its derived dyes. The 15 cases of bladder cancer diagnosed were all in the presynthesis group, although an excess of bladder cancer was also seen in the whole cohort. The standardised incidence ratio (SIR) of bladder cancer was 1918 in the whole cohort and 3500 in the presynthesis group. Moreover, the SIR of bladder cancer in a subgroup working directly with the assignment, transport, and mixing of benzidine was as high as 7500. A further retrospective cohort study was made on incidence of cancer among 1420 workers who used benzidine derived dyes in 43 textile printing and dyeing factories. No excess carcinoma was found. These results suggest that, in Shanghai, the main cause of bladder cancer is occupational exposure, especially to benzidine. The risk of bladder

    With the advent of high-level programming languages capable of quickly rendering three-dimensional simulations, the inclusion of computers as a learning tool in the classroom has become more prevalent. Although work has begun to study the patterns seen in implementing and assessing computation in introductory physics, more insight is needed to understand the observed effects of blending computation with physics in a group setting. In a newly adopted format of introductory calculus-based mechanics, called Projects and Practices in Physics, groups of students work on short modeling projects -- which make use of a novel inquiry-based approach -- to develop their understanding of both physics content and practice. Preliminary analyses of observational data of groups engaging with computation, coupled with synchronized computer screencast, has revealed a unique group interaction afforded by the practices specific to computational physics -- problem debugging.

    2015-01-01

    Full Text Available Background & aim: Bladder cancer is the second most common cancer of the urinary tract worldwide and the third most common cancer among Iranian males. Despite the relative high incidence of bladder cancer in Iran, no study has examined the relationship between dietary factors and bladder cancer. The aim of the present study was to investigate this relationship. Methods: The present case-control study was carried out on fifty-five patients with bladder cancer and including 110 cancer-free patients as controls. Dietary intake was evaluated using a food frequency questionnaire. To investigate the relationship between food items and bladder cancer, the subjects were classified according to the tertile of food items. The odds ratio was calculated for each tertile and the first tertile was considered as the reference group. Results: Our findings revealed that among food groups, animal fat (OR=19.76, fat (OR=12.92, junk foods (OR=8.1, organ meat (OR=5.47, processed meat (OR=5.34 and sweets (OR=3.62 were involved in the development of bladder cancer. In bladder carcinogenesis, an inverse association was recorded between consumption of low fat dairy products (OR=0.31, yoghurt (OR =0.14, fish (OR = 0.13, specific fruits (OR=0.13 and the development of bladder cancer. Conclusion: Animal products and sources of saturated fat are associated with an increased in risk of bladder cancer. The protective effect of olive oil, specific fruits, vegetables, low-fat dairy fermented was observed to reduce the risk of bladder cancer.

    Several pyridine-amide compounds appended with phenol/catechol groups are synthesized. These compounds consist of protected or deprotected phenol/catechol groups and offer pyridine, amide, and phenol/catechol functional groups. All compounds have been well-characterized by various spectroscopic methods, elemental analysis, thermal studies, and crystallography. The biological activities of all compounds were investigated while a few compounds significantly decreased the metabolic viability, growth and clonogenicity of T98G cells in dose dependent manner. Accumulation of ROS was observed in T98G cells, which displayed a compromised redox status as evident from increased cellular Caspase 3/7 activity and formation of micronuclei. The in silico pharmacokinetic studies suggest that all compounds have good bioavailability, water solubility and other drug-like parameters. A few compounds were identified as the lead molecules for future investigation due to their: (a) high activity against T98G brain, H-460 lung, and SNU-80 thyroid cancer cells; (b) low cytotoxicity in non-malignant HEK and MRC-5 cells; (c) low toxic risks based on in silico evaluation; (d) good theoretical oral bioavailability according to Lipinski ‘rule of five’ pharmacokinetic parameters; and (e) better drug-likeness and drug-score values.

    Full Text Available Objective: One of the risk factor for different psychiatric disorders has been indicated as hypovit-aminosis D. The present study aimed to compare 25 (OH D level between 4 different types of psychiatric disorders (schizophrenia, bipolar disorder, depression and anxiety disorder and healthy controls, and to assess the risk factors of hypovitaminosis D in psychiatric inpatients. Method: This retrospective study included 974 individuals [depression (n=553, bipolar disorder (n=135, schizophrenia (n=186 and anxiety disorder (n=100] who received inpatient treatment in psychiatry clinic between 2012 and 2014, and 574 individuals in control group who were not diagnosed with a psychiatric condition. A 25 (OH D level less than 21 ng/mL was considered to indicate hypovitaminosis D. Results: 25 (OH D level average of the control group was found to be significantly higher than that of the four psychiatric diagnosis groups (p0.05. Lo-gistic regression analysis of the study parameters suggested that the female gender (odds ratio: 3.46; 95% confidence interval: 0.99-1.01, winter and spring seasons (odds ratio: 2.56; 95% con-fidence interval: 1.69-3.86 and odds ratio: 2.03; 95% confidence interval: 1.33-3.11, respectively were significant predictors in level of vitamin D in psychiatric inpatients. Conclusions: Hypovitaminosis D is a condition that frequently exists in inpatients in psychiatry clinic suffering from schizophrenia, bipolar disorder, anxiety disorder and depression. Being a female, winter and spring are the most remarkable risk factors in these patients.

    Full Text Available This study evaluated the risk of cancer among patients with iron deficiency anemia (IDA by using a nationwide population-based data set.Patients newly diagnosed with IDA and without antecedent cancer between 2000 and 2010 were recruited from the Taiwan National Health Insurance Research Database. The standardized incidence ratios (SIRs of cancer types among patients with IDA were calculated.Patients with IDA exhibited an increased overall cancer risk (SIR: 2.15. Subgroup analysis showed that patients of both sexes and in all age groups had an increased SIR. After we excluded patients diagnosed with cancer within the first and first 5 years of IDA diagnosis, the SIRs remained significantly elevated at 1.43 and 1.30, respectively. In addition, the risks of pancreatic (SIR: 2.31, kidney (SIR: 2.23, liver (SIR: 1.94, and bladder cancers (SIR: 1.74 remained significantly increased after exclusion of patients diagnosed with cancer within 5 years after IDA diagnosis.The overall cancer risk was significantly elevated among patients with IDA. After we excluded patients diagnosed with IDA and cancer within 1 and 5 years, the SIRs remained significantly elevated compared with those of the general population. The increased risk of cancer was not confined to gastrointestinal cancer when the SIRs of pancreatic, kidney, liver, and bladder cancers significantly increased after exclusion of patients diagnosed with IDA and cancer within the first 5 years. This finding may be caused by immune activities altered by IDA. Further study is necessary to determine the association between IDA and cancer risk.

    Full Text Available Este estudo objetivou analisar o impacto psicológico do diagnóstico do câncer de mama a partir dos relatos apresentados espontaneamente por mulheres acometidas pela doença durante as sessões de um grupo de apoio. Utilizando-se o critério de saturação, foram selecionadas 18 sessões do referido grupo de apoio, das quais, no total, participaram 93 mulheres. Os dados coletados foram submetidos a uma apreciação qualitativa a partir do empreendimento de uma análise temática de conteúdo. Os resultados obtidos apontam que o diagnóstico do câncer de mama causou, entre uma parcela expressiva das participantes, um impacto psicológico importante, uma vez que desencadeou experiências de surpresa e tensão, ensejou demonstrações de aceitação e força, motivou tentativas de explicação, redefiniu relacionamentos e intensificou o recurso à religiosidade. O delineamento de cada um desses processos, em suas dimensões positivas e negativas, fornece elementos profícuos para o aperfeiçoamento da assistência psicológica oferecida a tal população.This study aimed to analyze breast cancer diagnosis' psychological impact since reports spontaneously presented during sessions of a support group for women diagnosed with this disease.

    Full Text Available The aim of this qualitative study was to explore the psychological barriers to and facilitators of undergoing the Hemoccult-II® colorectal cancer screening test in France. Sixty-nine French people aged 50 to 74 years were divided into seven qualitative focus groups. Three issues were discussed with participants: knowledge and beliefs about colorectal cancer screening; facilitators of colorectal cancer screening by Hemoccult-II®; barriers to colorectal cancer screening by Hemoccult-II®. All the discussions were led by two psychologists and were recorded, transcribed verbatim and analyzed using qualitative data analysis software. Correspondence factor analyses identified three dimensions for each topic. The main psychological facilitators of colorectal cancer screening were: information about colorectal cancer screening, perceived simplicity of using Hemoccult-II®, and perception of risk. Uncertainty about the reliability of Hemoccult-II®, health anxiety, and embarrassment emerged as the main barriers to colorectal cancer screening. Cross-sectional analyses identified the differences between the views expressed by women and men. Women appeared more embarrassed about Hemoccult-II® and men seemed to be more worried about colorectal cancer. This preliminary study suggests that psychological factors play an important role in colorectal cancer screening by Hemoccult-II®. This finding may help health organizations to conceive better awareness campaigns to promote colorectal cancer screening in order to reduce the related mortality rate by taking into account psychological determinants.

    AIM: To investigate the risk factors of colon cancer andrectal cancer.METHODS: A nested case-control study was conducted ina cohort of 64 693 subjects who participated in a colorectalcancer screening program from 1989 to 1998 in Jiashancounty, Zhejiang, China. 196 cases of colorectal cancer weredetected from 1990 to 1998 as the case group and 980non-colorectal cancer subjects, matched with factors of age,gender, resident location, were randomly selected from the64 693 cohort as controls. By using univariate analysis andmutivariate conditional logistic regression analysis, the oddsratio (OR) and its 95 % confidence interval (95 %CI) werecalculated between colorectal cancer and personal habits,dietary factors, as well as intestinal related symptoms.RESULTS: The mutivariate analysis results showed that aftermatched with age, sex and resident location, mucous bloodstool history and mixed sources of drinking water were closelyassociated with colon cancer and rectal cancer, OR values forthe mucous blood stool history were 3.508 (95 %CI: 1.370-8.985) and 2.139 (95 %CI: 1.040-4.402) respectively; for themixed drinking water sources, 2.387 (95 %CI: 1.243-4.587)and 1.951 (95 %CI: 1.086-3.506) respectively. All reachedthe significant level with a P-value less than 0.05.CONCLUSION: The study suggested that mucous bloodstool history and mixed sources of drinking water were therisk factors of colon cancer and rectal cancer. There was noany significant association between dietary habits and theincidence of colorectal cancer.

    BACKGROUND: Titanocene dichloride (TD) is an organometallic compound with antiproliferative properties in vitro and promising antitumor activity in preclinical in vivo models. The drug interferes with DNA, blocks the S/G(2) phase of the cell cycle and shows antiangiogenic properties. The purpose of this study was to determine the maximum tolerated dose (MTD) and the dose-limiting toxicity (DLT) of a 'split' dose administration schedule (days 1, 3, 5 q 3 weeks). PATIENTS AND METHOD: Patients with progressive advanced cancer and a creatinine clearance > 60 ml/min qualified for a treatment with TD after standard therapies (radio-, chemo-, hormone therapy) failed. A total of 10 patients (4 females, 6 males) with a median age of 58 (range 49-68) years were treated with 80 mg/m(2) TD at days 1, 3 and 5 (repeated at day 22). The drug was administered as light-protected infusion within 1 h. RESULTS: Significant side effects were as follows: nausea/vomiting, appetite loss, renal toxicity (elevation of serum creatinine and proteinuria) and liver toxicity (bilirubin and alkaline phosphatase elevation), but no myelosuppression. At the starting dose (3 x 80 = 240 mg/m(2) TD), renal (3 patients) or liver toxicity (1 patient) of grade 3 was judged as DLT. No further dose escalation was possible. No objective tumor remission was observed. CONCLUSION: The tolerability of TD cannot be improved by splitting the total dose in to three treatments every other day. Compared to previous phase I data using a 3-weekly and a 1-weekly schedule, the 'split' dose administration allowed no further increase of the total drug dose per treatment cycle. Thus, dose intensification by alterations of the application mode does not seem to be possible. Copyright 2000 S. Karger GmbH, Freiburg

    Pediatric pancreatitis is a rare disease with variable etiology. In the past 10-15 years the incidence of pediatric pancreatitis has been increased. The management of pediatric pancreatitis requires up-to-date and evidence based management guidelines. The Hungarian Pancreatic Study Group proposed to prepare an evidence based guideline based on the available international guidelines and evidences. The preparatory and consultation task force appointed by the Hungarian Pancreatic Study Group translated and complemented and/or modified the international guidelines if it was necessary. In 8 clinical topics (diagnosis; etiology; prognosis; imaging; therapy; biliary tract management; complications; chronic pancreatitis) 50 relevant questions were defined. Evidence was classified according to the UpToDate(®) grading system. The draft of the guidelines was presented and discussed at the consensus meeting on September 12, 2014. All clinical statements were accepted with total (more than 95%) agreement. The present Hungarian Pancreatic Study Group guideline is the first evidence based pediatric pancreatitis guideline in Hungary. The present guideline is the first evidence-based pancreatic cancer guideline in Hungary that provides a solid ground for teaching purposes, offers quick reference for daily patient care in pediatric pancreatitis and guides financing options. The authors strongly believe that these guidelines will become a standard reference for pancreatic cancer treatment in Hungary.

    The aims of this study were to make the lung cancer clinics in Korea Cancer Center Hospital, and to establish new therapeutic methods of lung cancer for increasing the cure rate and survival rate of patients. Also another purpose of this study was to establish a common treatment method in our hospital. All patients who were operated in Korea Cancer Center Hospital from 1987 due to lung cancer were followed up and evaluated. And we have been studied the effect of postoperative adjuvant therapy in stage I, II, IIIA non-small cell lung cancer patients from 1989 with the phase three study form. Follow-up examinations were scheduled in these patients and interim analysis was made. Also we have been studied the effect of chemo-therapeutic agents in small cell lung cancer patients from 1997 with the phase two study form. We evaluated the results of this study. Some important results of this study were as follows. 1. The new therapeutic method (surgery + MVP chemotherapy) was superior to the standard therapeutic one in stage I Non-small cell lung cancer patients. So, we have to change the standard method of treatment in stage I NSCLC. 2. Also, this new therapeutic method made a good result in stage II NSCLC patients. And this result was reported in The Annals of Thoracic Surgery. 3. However, this new therapeutic method was not superior to the standard treatment method (surgery only) in stage IIIA NSCLC patients. So, we must develop new chemo-therapeutic agents in the future for advanced NSCLC patients. 4. In the results of the randomized phase II studies about small cell lung cancer, there was no difference in survival between Etoposide + Carboplatin + Ifosfamide + Cisplatin group and Etoposide + Carboplatin + Ifosfamide + Cisplatin + Tamoxifen group in both the limited and extended types of small cell lung cancer patients.

    Objective The purposes of this study were to (1) assess the clinicoepidemiological characteristics of esopha-geal cancer patients, (2) analyze the prognostic factors determining treatment failure and survival, and (3) evaluate the results of various treatment modalities for locoregional and disseminated disease and their ef ect on disease-free survival and overal survival (OS). Methods Clinicoepidemiological retrospective data from 81 esophageal cancer patients treated at the Na-tional Cancer Institute of Cairo between 2007 and 2011 were evaluated. Results The study showed that patients with esophageal cancer commonly present with local y advanced disease (87.7% had T-stage 3 and 12.3% had T-stage 4). There was a significant correlation between surgery and survival; patients who received radical surgery and postoperative radiation had a better median survival than patients who received radical radiotherapy (20 months vs. 16 months, respectively; P = 0.04). There was also a significant statistical correlation between radical concomitant chemoradiotherapy (NCRT) and pal iative treatment. Patients who received radical NCRT had a better median survival than patients who received pal-liative radiotherapy (16 months vs. 10 months, respectively; P = 0.001). The median fol ow-up period for al patients was 7 months. The median OS of the whole group was 12 months. The OS after 1 and 2 years was 57.8% and 15%, respectively. Conclusion High-dose NCRT is an acceptable alternative for patients unfit for surgery or with inoperable disease. High-dose radiation is more ef ective than low-dose radiation in terms of local control, time to relapse, and OS. Further study using a larger series of patients and introducing new treatment protocols is necessary for a final evaluation.

    This study investigated the possible relationship between endocarditis and overall and individual cancer risk among study participants in Taiwan.We used data from the National Health Insurance program of Taiwan to conduct a population-based, observational, and retrospective cohort study. The case group consisted of 14,534 patients who were diagnosed with endocarditis between January 1, 2000 and December 31, 2010. For the control group, 4 patients without endocarditis were frequency matched to each endocarditis patient according to age, sex, and index year. Competing risks regression analysis was conducted to determine the effect of endocarditis on cancer risk.A large difference was noted in Charlson comorbidity index between endocarditis and nonendocarditis patients. In patients with endocarditis, the risk for developing overall cancer was significant and 119% higher than in patients without endocarditis (adjusted subhazard ratio = 2.19, 95% confidence interval = 1.98-2.42). Regarding individual cancers, in addition to head and neck, uterus, female breast and hematological malignancies, the risks of developing colorectal cancer, and some digestive tract cancers were significantly higher. Additional analyses determined that the association of cancer with endocarditis is stronger within the 1st 5 years after endocarditis diagnosis.This population-based cohort study found that patients with endocarditis are at a higher risk for colorectal cancer and other cancers in Taiwan. The risk was even higher within the 1st 5 years after endocarditis diagnosis. It suggested that endocarditis is an early marker of colorectal cancer and other cancers. The underlying mechanisms must still be explored and may account for a shared risk factor of infection in both endocarditis and malignancy.

    We present results from combined low-frequency radio and X-ray studies of nearby galaxy groups. We consider two main areas: firstly, the evolutionary process from spiral-dominated, HI-rich groups to elliptical-dominated systems with hot, X-ray emitting gas halos; secondly, the mechanism of AGN feedback which appears to balance radiative cooling of the hot halos of evolved groups. The combination of radio and X-ray observations provides a powerful tool for these studies, allowing examination of gas in both hot and cool phases, and of the effects of shock heating and AGN outbursts. Low-frequency radio data are effective in detecting older and less energetic electron populations and are therefore vital for the determination of the energetics and history of such events. We present results from our ongoing study of Stephan's Quintet, a spiral-rich group in which tidal interactions and shock heating appear to be transforming HI in the galaxies into a diffuse X-ray emitting halo, and show examples of AGN feedback fr...

    Full Text Available The purpose of this study was to examine the effect of a therapeutic laughter program and the number of program sessions on anxiety, depression, and stress in breast cancer patients. A randomized controlled trial was conducted involving 31 patients who received four sessions of therapeutic laughter program comprised and 29 who were assigned to the no-program control group. Scores for anxiety, depression, and stress were measured using an 11-point numerical rating scale. While no change was detected in the control group, the program group reported reductions of 1.94, 1.84, and 2.06 points for anxiety, depression, and stress, respectively (p<0.01, p<0.01, and p<0.01. Scores decreased significantly after the first therapeutic laughter session (p<0.05, p<0.01, and p<0.01. As the therapeutic laughter program was effective after only a single session in reducing anxiety, depression, and stress in breast cancer patients, it could be recommended as a first-line complementary/alternative therapy.

    Array-centred and subarray-centred neglect were disambiguated in a group of 116 patients with left neglect by means of a modified version of the Albert test in which the central column of segments was deleted so as to create two separate sets of targets grouped by proximity. The results indicated that neglect was more frequent in array- than subarray-centred coordinates and that, in a minority of cases, neglect co-occurred in both coordinate-systems. The two types of neglect were functionally but not anatomically dissociated. Presence of visual field defects was not prevalent in one type of neglect with respect to the other. These data contribute further evidence to previous single-case and small-group studies by showing that neglect can occur in single or multiple reference frames simultaneously, in agreement with current neuropsychological, neurophysiological and computational concepts of space representation.

    Cancer incidence and death statistics are typically recorded for multiple age and sex brackets, leading to large data tables which are difficult to digest. Effective visualizations of this data would allow practitioners, policy makers, and the general public to comprehend the data more readily and act on it appropriately. We introduce multilevel spie charts to create a combined visualization of cancer incidence and death statistics. Spie charts combine multiple pie charts, where the base pie chart (representing the general population) is used to set the angles of slices, and the superimposed ones use variable radii to portray the cancer data. Spie charts of cancer incidence and death statistics from Israel for 2009-2011 are used as an illustration. These charts clearly show various patterns of how cancer incidence and death distribute across age and sex groups, illustrating (1) absolute numbers and (2) rates per 100,000 population for different age and sex brackets. In addition, drawing separate charts for different cancer types illustrates relative mortality, both (3) across cancer types and (4) mortality relative to incidence. Naturally, this graphical depiction can be used for other diseases as well.

    Full Text Available Background: Cancer has become one of the ten leading causes of death in India. Breast cancer is the most common diagnosed malignancy in India, it ranks second to cervical cancer. An increasing trend in incidence is reported from various registries of national cancer registry project and now India is a country with largest estimated number of breast cancer deaths worldwide. Aim: To study the factors associated with breast cancer. Objectives: To study the association between breast cancer and selected exposure variables and to identify risk factors for breast cancer. Materials and Methods: A hospital based Case control study was conducted at Shirdi Sai Baba Cancer Hospital and Research Center, Manipal, Udupi District. Results: Total 188 participants were included in the study, 94 cases and 94 controls. All the study participants were between 25 to 69 years of age group. The cases and controls were matched by ± 2 years age range. Non vegetarian diet was one of the important risk factors (OR 2.80, CI 1.15-6.81. More than 7 to 12 years of education (OR 4.84 CI 1.51-15.46 had 4.84 times risk of breast cancer as compared with illiterate women. Conclusion: The study suggests that non vegetarian diet is the important risk factor for Breast Cancer and the risk of Breast Cancer is more in educated women as compared with the illiterate women. Limitation: This is a Hospital based study so generalisability of the findings could be limited.

    Young patients with breast cancer (BC) are often concerned about treatment-induced infertility and express maternity desire. Conception after BC does not seem to affect outcome, but information in estrogen-receptor positive (ER+) disease is not definitive. From September 2012-March 2013, 212 evaluable patients with ER+ early BC, pregnancy. Overall, 37% of respondents were interested in the study; younger patients (≤30 years) reported higher interest (57%). Motivation in younger patients treated >30 months was higher (83%) than in older women (14%), interest was independent of age in patients treated for ≤30 months. A prospective study in this patient population seems relevant and feasible. The International-Breast-Cancer-Study-Group (IBCSG), within the Breast-International-Group (BIG) - North-American-Breast-Cancer-Groups (NABCG) collaboration, is launching a study (POSITIVE) addressing ET interruption to allow pregnancy.

    Zanella, J

    2006-01-01

    In this paper we shall study whether dissipation in a $\\lambda\\phi^{4}$ may be described, in the long wavelength, low frequency limit, with a simple Ohmic term $\\kappa\\dot{\\phi}$, as it is usually done, for example, in studies of defect formation in nonequilibrium phase transitions. We shall obtain an effective theory for the long wavelength modes through the coarse graining of shorter wavelengths. We shall implement this coarse graining by iterating a Wilsonian renormalization group transformation, where infinitesimal momentum shells are coarse-grained one at a time, on the influence action describing the dissipative dynamics of the long wavelength modes. To the best of our knowledge, this is the first application of the nonequilibrium renormalization group to the calculation of a damping coefficient in quantum field theory.

    The beryllium hydride (BeH)- dimer has recently been shown to be surprisingly strongly bound, with an electronic structure which is highly dependent on internuclear separation. At the equilibrium distance, the negative charge is to be found on the beryllium atom, despite the higher electronegativity of the hydrogen. The current study expands this investigation to the other Group 2 hydrides, and attempts to explain these effects. M. Verdicchio, G. L. Bendazzoli, S. Evangelisti, T. Leininger J. Phys. Chem.

    Full Text Available Background: The microscopic structure of spleen is variable depending on the developmental stage of the organ, and the age and immune status of the individual. The aim of the investigation was to study the microscopic structure of human spleen in different age groups, starting from a six month old foetus up to the eighth decade of life. Methods: Seventy formalin fixed human spleens obtained postmortem, were included in the study. They were classified into different age groups, in both sexes, for a detailed study of the microscopic details. Results: The white pulp of spleen showed peri-arteriolar lymphatic sheath (PALS and lymphatic follicles. The corona or mantle zone and the germinal centre were discernible in many of the Malpighian bodies. The marginal zone separating the red pulp from the white pulp also could be clearly demarcated. The marginal sinus and peri-follicular zone could be seen in some sections only. The capsule thickness, trabecular network, cellularity of white pulp and red pulp, the connective tissue framework seen in the red pulp etc., showed variations in the different age groups. Conclusion: The microscopic structure of spleen varies in different age groups, with the PALS and the white pulp showing scanty cellularity in the six month foetus, and almost uniform cellularity in all areas of spleen at full term. Thereafter the follicles showed increase in its cellularity up to the third decade, and then seemed becoming progressively atrophic. Further studies are required on age related changes in the cellular architecture of this organ correlating with its functions. [Int J Res Med Sci 2015; 3(7.000: 1701-1706

    Full Text Available Background: DNA methyltransferase-3B (DNMT3B is an important enzyme responsible for maintaining the DNA methylation pattern in eukaryotic cells. In this study we have investigated the correlation between the 46359C→T polymorphism in the DNMT3B gene and the risk of breast cancer incidence among sporadic breast cancer patients in Fars Province, Southern Iran. Methods: In this case-control study, 100 breast cancer patients and 138 healthy control subjects were genotyped for the DNMT3B gene by the polymerase chain reaction-restriction fragment length polymorphism method. Results: The genotype frequency in the case (CC 27%, CT 47%, TT 26% group significantly (P=0.008 differed from the control (CC 19.56%, CT 67.3%, TT 13% group. We observed a decreased association between the CT genotype and lymph node involvement in breast cancer patients. Our results have shown that in comparison to the homozygous CC genotype carriers the DNMT3B-CT genotype has a significantly lower risk for breast cancer (OR=0.515, 95% CI=0.267-0.994, P=0.048. Conclusion: Our case-control study showed that the CT genotype was significantly associated with decreased breast cancer risk. Consistent with these results, a significant decrease of CT genotype among lymph node positive breast cancer patients was observed. However, a larger study population with more clinical data is needed to confirm these results.

    Full Text Available Abstract Background A cancer diagnosis is 2.9 times more likely to occur during the adolescent and young adult years than in younger children. This spike in incidence coincides with a life stage characterised by psychological vulnerability as young people strive to attain numerous, critical developmental milestones. The distress young people experience after cancer treatment seriously jeopardises their ability to move into well-functioning adulthood. Methods/Design This article presents the protocol of the Recapture Life study, a phase II three-arm randomised controlled trial designed to evaluate the feasibility and efficacy of a new intervention in reducing distress and improving quality of life for adolescent and young adult cancer survivors. The novel intervention, “ReCaPTure LiFe” will be compared to a both a wait-list, and a peer-support group control. Ninety young people aged 15–25 years who have completed cancer treatment in the past 1–6 months will be recruited from hospitals around Australia. Those randomised to receive Recapture Life will participate in six, weekly, 90-minute online group sessions led by a psychologist, involving peer-discussion around cognitive-behavioural coping skills (including: behavioural activation, thought challenging, communication and assertiveness skills training, problem-solving and goal-setting. Participants randomised to the peer-support group control will receive non-directive peer support delivered in an identical manner. Participants will complete psychosocial measures at baseline, post-intervention, and 12-months post-intervention. The primary outcome will be quality of life. Secondary outcomes will include depression, anxiety, stress, family functioning, coping, and cancer-related identity. Discussion This article reviews the empirical rationale for using group-based, online cognitive-behavioural therapy in young people after cancer treatment. The potential challenges of delivering skills

    Full Text Available Childhood cancer was the leading cause of death among children aged 1-14 years for 2012 in Spain. Leukemia has the highest incidence, followed by tumors of the central nervous system (CNS and lymphomas (Hodgkin lymphoma, HL, and Non-Hodgkin's lymphoma, NHL. Spatial distribution of childhood cancer cases has been under concern with the aim of identifying potential risk factors.The two objectives are to study overall spatial clustering and cluster detection of cases of the three main childhood cancer causes, looking to increase etiological knowledge.We ran a case-control study. The cases were children aged 0 to 14 diagnosed with leukemia, lymphomas (HL and NHL or CNS neoplasm in five Spanish regions for the period 1996-2011. As a control group, we used a sample from the Birth Registry matching every case by year of birth, autonomous region of residence and sex with six controls. We geocoded and validated the address of the cases and controls. For our two objectives we used two different methodologies. For the first, for overall spatial clustering detection, we used the differences of K functions from the spatial point patterns perspective proposed by Diggle and Chetwynd and the second, for cluster detection, we used the spatial scan statistic proposed by Kulldorff with a level for statistical significance of 0.05.We had 1062 cases of leukemia, 714 cases of CNS, 92 of HL and 246 of NHL. Accordingly we had 6 times the number of controls, 6372 controls for leukemia, 4284 controls for CNS, 552 controls for HL and 1476 controls for NHL. We found variations in the estimated empirical D(s for the different regions and cancers, including some overall spatial clustering for specific regions and distances. We did not find statistically significant clusters.The variations in the estimated empirical D(s for the different regions and cancers could be partially explained by the differences in the spatial distribution of the population; however, according to the

    1987-05-01

    From a waiting list consisting of hearing-impaired patients waiting for hearing aids to be fitted, 39 subjects who at interview also stated that they had tinnitus took part in an experimental group study with the aim of investigating the effect of a hearing aid on tinnitus. No subject had any previous experience of hearing aids. The subjects were randomly allocated to a treatment and a waiting list control group. After an initial interview, the routine programme for the fitting of hearing aids started in the treatment group, while the waiting list control group had to wait for 6 weeks before starting the same hearing aid rehabilitation programme. The hearing aids were fitted exclusively for hearing purposes. As expected, the hearing aids improved the hearing capacity, but they did not reduce tinnitus as recorded on a visual analogue scale. According to information obtained at the final interview, there were significant differences in tinnitus between subjects who used their aid for more than 2 hours daily and those who used it for less than 2 hours. However, the results of scaling (pre- and post-fitting) did not support this finding. The discrepancy between the scaling and interview data is probably due to demand characteristics.

    Full Text Available The aim of this study is to contribute to the knowledge on innovation in accounting tasks, from the point of view of two professional groups. Its goals are: evaluating the importance given by the professionals to accounting tasks; identifying whether there is convergence between the two professional groups, regarding the importance of the tasks; examining whether there is an association between the professionals’ individual characteristics and the importance they attach to the tasks. Two professional groups were surveyed: 105 financial officers of the top 500 Portuguese companies; and 412 Chartered Accountants. The results obtained allowed us to conclude that the respondents attach more importance to the traditional tasks, linked to the concept of a monetary-oriented accountant, and less importance to the more innovative tasks, related to business strategy; there is no convergence between the two professional groups in terms of the importance of the accountants’ participation in the strategic tasks. Regarding the association between individual characteristics and the level of importance assigned to the accounting tasks, we found an influence of the following characteristics: gender; academic degree of the professionals; and the institution where that degree was obtained.

    Full Text Available The literature linking breast cancer with oral contraceptives and BRCA mutation as possible risk factors is equivocal. Hence, to account for these conflicting results in the existing literature and to observe the net effect, this meta-analysis aims to investigate whether oral contraceptives are a risk factor for developing breast cancer in breast cancer (BRCA gene carrier female in the 30-60 years age group. Method: Systematic review of the literature, both published and unpublished, and meta-analysis of relevant data. Results: Meta-analysis of data from five relevant studies, with a total of 6682 BRCA carriers (3,269 BRCA1 carriers and 791 BRCA2 carriers, revealed that use of oral contraceptives is associated with increased risk of breast cancer among BRCA mutation carriers (OR=2.267; 95 % CI= 1.311, 3.919. When the same risk was stratified by mutation type, both BRCA1 and BRCA2 were at increased risk. However, BRCA2 carriers (OR= 3.060; 95% CI=0.951, 9.848 were found to be at elevated risk compared to BRCA1 carriers (OR= 2.347; 95% CI=0.939, 5.865. Conclusions: This meta-analytical finding suggests that oral contraceptives are a risk factor for developing breast cancer in breast cancer (BRCA gene carrier females.

    2016-01-01

    This study examined adolescent girls' views of cosmetic surgery. Seven focus groups were run with girls aged 15-18 years (N = 27). Participants read case studies of women having cosmetic surgery, followed by discussion and exploration of their views. Thematic analysis identified four themes: (1) dissatisfaction with appearance, (2) acceptability of cosmetic surgery, (3) feelings about undergoing cosmetic surgery and (4) cosmetic surgery in the media. Results suggest the acceptability of cosmetic surgery varies according to the reasons for having it and that the media play an important role by normalising surgery and under-representing the risks associated with it.

    This technical note describes some Bayesian procedures for the analysis of group studies that use nonlinear models at the first (within-subject) level - e.g., dynamic causal models - and linear models at subsequent (between-subject) levels. Its focus is on using Bayesian model reduction to finesse the inversion of multiple models of a single dataset or a single (hierarchical or empirical Bayes) model of multiple datasets. These applications of Bayesian model reduction allow one to consider parametric random effects and make inferences about group effects very efficiently (in a few seconds). We provide the relatively straightforward theoretical background to these procedures and illustrate their application using a worked example. This example uses a simulated mismatch negativity study of schizophrenia. We illustrate the robustness of Bayesian model reduction to violations of the (commonly used) Laplace assumption in dynamic causal modelling and show how its recursive application can facilitate both classical and Bayesian inference about group differences. Finally, we consider the application of these empirical Bayesian procedures to classification and prediction.

    During the past decade planning of adjuvant radiotherapy (RT) of early breast cancer has changed from two-dimensional (2D) to 3D conformal techniques. In the planning computerised tomography (CT) scan both the targets for RT and the organs at risk (OARs) are visualised, enabling an increased focus...... on target dose coverage and homogeneity with only minimal dose to the OARs. To ensure uniform RT in the national prospective trials of the Danish Breast Cancer Cooperative Group (DBCG), a national consensus for the delineation of clinical target volumes (CTVs) and OARs was required....

    Objective: The aim of this study was to use lung cancer targeting binding polypeptide ZS-9 to screen cDNA library of human lung cancer and obtain ZS-9 specific ligand to confirm tumor marker of non small-cell lung cancer. Methods: Artificially synthesize biotin labeled peptide ZS-9, anchored ZS-9 in the enzyme label plate coupled by avidin, used ZS-9 as probe to screen cDNA library of human lung cancer, after screening, obtained bacteriophage clone specifically binding with anchored polypeptide ZS-9. Extracted plasmid of bacteriophage and performed sequencing after amplified by PCR. Results: It was demonstrated by bioinformatic analysis on the sequence of ligand binded by lung cancer specific peptide ZS-9 that the ligand was the cytoskeletal protein periplakin on the surface of lung cancer cells, suggesting that periplakin might be a new marker for non-small-cell lung cancer in lung cancer. Conclusion: Use specific lung cancer binding peptide to screen new tumor marker periplakin in lung cancer and further studies on its biologic functions in genesis and development of lung cancer are still needed.

    AIM:To investigate barriers to colorectal cancer (CRC) screening in a community population. METHODS:We conducted a community-based case-control study in an urban Chinese population by questionnaire. Cases were selected from those completing both a fecal occult blood test (FOBT) case and colonoscopy in a CRC screening program in 2004. Control groups were matched by gender, age group and community. Control 1 included those having a positive FOBT but refusing a colonoscopy. Control 2 included those who refused both an FOBT and colonoscopy. RESULTS:The impact of occupation on willingness to attend a colorectal screening program differed by gender. P for heterogeneity was 0.009 for case vs control group 1, 0.01 for case versus control group 2, and 0.80 for control group 1 vs 2. Poor awareness of CRC and its screening program, characteristics of screening tests, and lack of time affected the screening rate. Financial support, fear of pain and bowel preparation were barriers to a colonoscopy as a screening test. Eighty-two percent of control group 1 and 87.1% of control group 2 were willing attend if the colonoscopy was free, but only 56.3% and 53.1%,respectively, if it was self-paid. Multivariate odds ratios for case vs control group 1 were 0.10 among those unwilling to attend a free colonoscopy and 0.50 among those unwilling to attend a self-paid colonoscopy. CONCLUSION:Raising the public awareness of CRC and its screening, integrating CRC screening into the health care system, and using a painless colonoscopy would increase its screening rate.

    Full Text Available INTRODUCTION: In Mexico, breast cancer (BC is one of the main causes of cancer deaths in women, with increasing incidence and mortality in recent years. Therefore, the aim of the study is identify possible risk factors related to BC. METHODS: An epidemiological study of hospital cases of BC and controls with cervical uterine cancer (CUCA was carried out at eight third level concentration hospitals in Mexico City. The total of 353 incident cases of BC and 630 controls with CUCA were identified among women younger than 75 years who had been residents of the metropolitan area of Mexico City for at least one year. Diagnosis was confirmed histologically in both groups. Variables were analyzed according to biological and statistical plausibility criteria. Univariate, bivariate and multivariate analyses were carried out. Cases and controls were stratified according to the menopausal hormonal status (pre and post menopause. RESULTS: The factors associated with BC were: higher socioeconomic level (OR= 2.77; 95%CI = 1.77 - 4.35; early menarche (OR= 1.32; 95%CI= 0.88 - 2.00; old age at first pregnancy (>31 years: OR= 5.49; 95%CI= 2.16 - 13.98 and a family history of BC (OR= 4.76; 95% CI= 2.10 - 10.79. In contrast, an increase in the duration of the breastfeeding period was a protective factor (>25 months: OR= 0.38; 95%CI= 0.20 - 0.70. CONCLUSIONS: This study contributes to the identification of risk factors for BC described in the international literature, in the population of Mexican women. Breastfeeding appears to play an important role in protecting women from BC. Because of changes in women`s lifestyles, lactation is decreasing in Mexico, and young women tend not to breastfeed or to shorten the duration of lactation.

    Purpose: To prospectively assess the performance of teleradiology-based CT colonography to screen a population group of an island, at average risk for colorectal cancer. Materials and methods: A cohort of 514 patients living in Madeira, Portugal, was enrolled in the study. Institutional review board approval was obtained and all patients signed an informed consent. All patients underwent both CT colonography and optical colonoscopy. CT colonography was interpreted by an experienced radiologist at a remote centre using tele-radiology. Per-patient sensitivity, specificity, positive (PPV) and negative (NPV) predictive values with 95% confidence intervals (95%CI) were calculated for colorectal adenomas and advanced neoplasia ≥6 mm. Results: 510 patients were included in the study. CT colonography obtained a per-patient sensitivity, specificity, PPV and, NPV for adenomas ≥6 mm of 98.11% (88.6–99.9% 95% CI), 90.97% (87.8–93.4% 95% CI), 56.52% (45.8–66.7% 95% CI), 99.75% (98.4–99.9% 95% CI). For advanced neoplasia ≥6 mm per-patient sensitivity, specificity, PPV and, NPV were 100% (86.7–100% 95% CI), 87.07% (83.6–89.9% 95% CI), 34.78% (25.3–45.5% 95% CI) and 100% (98.8–100% 95% CI), respectively. Conclusion: In this prospective trial, teleradiology-based CT colonography was accurate to screen a patient cohort of a remote island, at average risk for colorectal cancer.

    The aim of this study was to assess the accuracy of the copper/zinc ratio (Cu/Zn ratio) in the evaluation of a large group of patients with digestive cancer compared to gender and age-matched control subjects. A total of 282 patients was studied and separated into three groups: group I (n = 75), patients with digestive cancer, group II (n = 112), patients with benign digestive disease, and group III (n = 95), healthy subjects. Serum levels of copper and zinc were measured by atomic absorption spectrophotometry. The results showed that the serum levels of copper (mg/dL) in patients with digestive cancer (91.6 +/- 27.3, p cancer (1.45 +/- .58, p copper/zinc ratio was 82.2%, with a specificity of 65.7%, a positive predictive value of 45.8% and a negative predictive value of 91.3%. In conclusion, Cu/Zn ratio was found to be considerably higher in patients with digestive cancer compared to age- and gender-matched controls, with a sensitivity of 82.2% that might be useful in the evaluation of suspected malignancy.

    N-nitroso compounds and their precursors, nitrites and nitrates, have been hypothesized as risk factors, and vitamins C and E, which inhibit N-nitroso formation, as protective factors for brain tumors. A case-control study of maternal diet during pregnancy and risk of astrocytoma, the most common childhood brain tumor, was conducted by the Childrens Cancer Group. The study included 155 cases under age six at diagnosis and the same number of matched controls selected by random-digit dialing. A trend was observed for consumption of cured meats, which contain preformed nitrosamines (a class of N-nitroso compounds) and their precursors (adjusted odds ratio [OR] for highest quartile of intake relative to lowest = 1.7, P trend = 0.10). However, no strong trends were observed for nitrosamine (OR = 0.8, P = 0.60); nitrite (OR = 1.3, P = 0.54); nitrate (OR = 0.7, P = 0.43); vitamin C (OR = 0.7, P = 0.37); or vitamin E (OR = 0.7, P = 0.48). Iron supplements were associated with a significant decrease in risk (OR = 0.5, 95 percent confidence interval = 0.3-0.8). The effect of several dietary factors differed by income level, making interpretation of the results difficult. Future research should investigate the effect of dietary components not assessed in this study, as these may explain the disparate effects by income level. The results of this study provide limited support for the nitrosamine hypothesis.

    Full Text Available Breast cancer is a major killer disease in females globally and in developing regions, where the early cancer detection facilities are unavailable, prognosis is even worse. Awareness about this disease can lead to early detection and thereby decrease the morbidity and mortality. A self designed questionnaire was used to study the level of awareness regarding breast cancer among males. The questionnaire had 15 questions and on the basis on score attained, the subjects were classified as having poor, average or good breast cancer awareness. Out of 624 participants, 555(89% had poor breast cancer awareness and 47(7.5% had average awareness. Only 22 (3.5% had good awareness about breast cancer. The level of awareness regarding female breast cancer in Kashmiri males is very low. Measures need to be taken to spread awareness about this disease in males so that they can play a vital role in early detection of this disease.

    Considering the paucity of studies dealing with the holistic aspect of the cancer experience, this grounded theory study seeks to conceptualize the process of cancer survivorship among Filipinos. Twenty-seven Filipino cancer survivors were purposively selected, and a two-part instrument, specifically robotfoto and focus group interviews, was used to gather data. The Glaserian method of grounded theory analysis was used, and extended texts were analyzed inductively via a dendrogram. Member checking and correspondence were observed to validate the surfacing stages, leading to the conceptualization of a theoretical model termed as the Ribbon of Cancer Survivorship. The said model describes the trifling (living before), transfusing (accepting the reality), transforming (being strong), and transcending (living beyond) phases of cancer survivorship. Ten interesting substages were also identified, namely: tainting, desolating, disrupting, and embracing for the transfusing phase; tormenting, distressing, awakening, and transfiguring for the transforming phase, and trembling and enlivening for the transcending phase. The resulting theoretical model has clearly and successfully described the entire process of cancer survivorship among Filipinos. It is hoped that the model be used as a reference for future studies about cancer survivorship and as a guide for nurses in providing a more empathetic care among cancer patients.

    Full Text Available This study determines the effect of Morindia citrifolia juice (Tahitian Noni® in the development of breast cancer induced by carcinogen agent 7.12-dimethylbenzanthracene (DMBA in rats. For this purpose, the breast cancer induction model 1.7-DMBA was used on Spraguey Dawley nulliparous rats of 35 days of age, randomly divided into three groups: group 1 control, which received no treatment, and groups 2 and 3, induced with DMBA at a dose of 55 mg/kg. The latter received a dose of noni juice of 4 ml/kg per day for 90 days. The results showed that a significant percentage (83.33% of the rats from the group induced with DMBA not treated with noni juice developed palpable breast tumors ( ≤ 2 cm of the ductal carcinoma in situ type and atypical ductal hyperplasia, compared to the other groups that did not develop any kind of tumors. In addition, it was found that rats that developed breast cancer had a lower weight gain and significantly increased water consumption (p < 0.05 compared to the other two groups. The results of the hematological and biochemical parameters showed no significant changes between groups. Histopathological changes compatible with liver toxicity were found in rats treated with noni juice. In conclusion, it was found in this preliminary study that noni juice has positive effects in modulating the development of breast cancer induced by DMBA.

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

    2011-09-01

    Full Text Available Objective: Cancer has been recognized to have environmental origin, but occupational cancer risk studies have not been fully documented. The objective of this paper was to identify occupations and industries with elevated colon cancer risk based on lifetime occupational histories collected from 15,463 incident cancer cases. Method: A group matched case-control design was used. All cases were diagnosed with histologically proven colon cancers, with cancer controls being all other cancer sites, excluding rectum, lung and unknown primary, diagnosed at the same period of time from the British Columbia Cancer Registry. Data analyses were done on all 597 Canadian standard occupation titles and 1,104 standard industry titles using conditional logistic regression for matched data sets and the likelihood ratio test. Results: Excess colon cancer risks was observed in a number of occupations and industries, particularly those with low physical activity and those involving exposure to asbestos, wood dusts, engine exhaust and diesel engine emissions, and ammonia. Discussion: The results of our study are in line with those from the literature and further suggest that exposure to wood dusts and to ammonia may carry an increased occupational risk of colon cancer.

    Heats of formation (HOF) for a series of energetic materials containing SF5 group were studied by density functional theory. Results show that HOFs increase with the augmention of field effects of substituted groups. Addition of furazan or furoxan ring increases HOF of the energetic materials. All the SF5-containing compounds have densities which are ∼0.19 g/cm3 higher than those containing -NH2 group. S-F bond is the trigger bond for the thermolysis process in the title compounds and bond dissociation energies of the weakest bonds range from 351.1 to 388.3 kJ/mol. Detonation velocities (D) and pressures (P) are evaluated by Kamlet-Jacobs equations with the calculated densities and HOFs. Results show that increasing the amount of furazan rings results in a larger D and P. Considering the detonation performance and thermal stability, eight compounds may be considered as potential candidates for high-energy density materials.

Controls were also males chosen from the Cancer Registry with two controls per case, matched on age and year of registration. There was an elevated risk in the upper social class groupings. The data did not support the findings, from other countries, of elevated risks in agricultural workers (odds ratio = 1.08, 90% confidence limits 0.86-1.36). The only occupational groups showing elevated risks were sales and service workers (odds ratio = 1.29, 90% confidence limits 0.99-1.69) and teachers (odds ratio = 2.44, 90% confidence limits 1.05-5.70). The New Zealand data do not in general suggest that occupational factors--or lifestyle factors associated with occupation--are of major direct importance in the aetiology of prostate cancer.

    2009-04-01

    Full Text Available Abstract Background Breast cancer management has improved dramatically in the past three decades and as a result, a population of working age women is breast cancer survivor. Interventions for breast cancer survivors have shown improvements in quality of life and in physical and psychological states. In contrast, efforts aimed at stimulating re-employment and return-to-work interventions for breast cancer survivors have not kept pace. The objective of this review was to study the effects and characteristics of intervention studies on breast cancer survivors in which the outcome was return to work. Methods The Cochrane Controlled Trials Register (The Cochrane Library, Issue 4, 2006, Medline, Ovid, EMBASE and PsychInfo were systematically searched for studies conducted between 1970 to February 2007. Intervention studies for female breast cancer survivors that were focused on return to work were included. Results Our search strategy identified 5219 studies. Four studies out of 100 potentially relevant abstracts were selected and included 46–317 employed women who had had mastectomy, adjuvant therapy and rehabilitation, with the outcome return to work. The intervention programs focused on improvement of physical, psychological and social recovery. Although a substantial percentage (between 75% to 85% of patients included in these studies returned to work after rehabilitation, it is not clear whether this proportion would have been lower for patients without counseling or exercise, or any other interventions, as three out of four studies did not include a comparison group. Conclusion The most important finding of this review is the lack of methodologically sound intervention studies on breast cancer survivors with the outcome return to work. Using evidence from qualitative and observational studies on cancer and the good results of intervention studies on return to work programs and vocational rehabilitation, return to work interventions for breast

    Several countries have acknowledged the contributions made by national logistics working groups (NLWG) to ensure equitable access to the expanded program on immunization's (EPI) vaccines against preventable diseases. In order to provide key insights to the United Nations Children's Fund (UNICEF) and the World Health Organization (WHO) supply chain hub - as well as other players, including national EPI - a landscape analysis study was conducted from September 2015 to February 2016. This is a cross-sectional survey taken by 43 countries that combines qualitative and quantitative approaches. Data was collected through a desk review, consultation, interviews, and distance questioning. References and guidance were used to determine and specify the underlying mechanisms of NLWGs. The key findings are:This study has provided a general overview of the status of NLWGs for immunization in various countries. Based on the key insights of the study, technical assistance needs have been identified, and immunization partners will be required to help countries create and reinforce their NLWGs.

    Purpose We described unmet information and service needs of adolescent and young adult (AYA) cancer survivors (15-39 years of age) and identified sociodemographic and health-related factors associated with these unmet needs. Methods We studied 523 AYAs recruited from 7 population-based cancer registries, diagnosed with acute lymphocytic leukemia, Hodgkin lymphoma, non-Hodgkin lymphoma, germ cell cancer or sarcoma in 2007-08. Participants completed surveys a median of 11 months from diagnosis. Multivariable logistic regression analyses were used to estimate associations between unmet (information and service) needs and sociodemographic and health-related factors. Results More than half of AYAs had unmet information needs relating to their cancer returning and cancer treatments. AYAs needing services, but not receiving them, ranged from 29% for in-home nursing to 75% for a support group. The majority of AYAs who needed a pain management expert, physical/occupational therapist, mental health worker or financial advice on paying for health care did not receive services. In multivariable analyses, older participants, men, participants of non-White race/ethnicity, and participants who reported less than excellent general health, or fair/poor quality of care were more likely to report unmet information needs. Factors associated with both unmet service and information needs included physical health or emotional problems interfering with social activities or having ≥ 3 physical treatment-related symptoms. Conclusions Recently diagnosed AYA cancer survivors have substantial unmet information needs varying by demographic and health-related factors. Implications for Cancer Survivors We identified subgroups of AYA cancer survivors with high unmet needs that can be targeted for interventions and referrals. PMID:22457219

    We numerically study the spin-1/2 antiferromagnetic Heisenberg model on the kagome lattice using the density-matrix renormalization group method. We find that the ground state is a magnetically disordered spin liquid, characterized by an exponential decay of spin-spin correlation function in real space and a magnetic structure factor showing system-size independent peaks at commensurate magnetic wave vectors. We obtain a spin triplet excitation gap DeltaE(S=1)=0.055+/-0.005 by extrapolation based on the large size results, and confirm the presence of gapless singlet excitations. The physical nature of such an exotic spin liquid is also discussed.

    Medical care is increasingly a technical business, and hospitalised patients are more and more susceptible to infections, notably due to the application of aggressive therapies for all kinds of disorders. As a consequence the epidemiology of hospital infections requires serious attention. Following the initiative of some medical microbiologists in the Netherlands, a study group was established to tackle this epidemiology and to initiate relevant research (Working party on Hospital Infections and Epidemiology of the Netherlands; WHEN). Recent subjects include fungemia in hospitalised patients, risk factors for acquiring methicillin-resistant Staphylococcus aureus during a stay abroad, and prevalence of vancomycin-resistant enterococci.

    High intakes of calcium and dairy products have been suggested to be related to prostate cancer risk. Such associations were examined in the Multiethnic Cohort Study (1993-2002) among 82,483 men who completed a detailed quantitative food frequency questionnaire. During a mean follow-up of 8 years, 4,404 total cases of prostate cancer were identified. In Cox proportional hazards models, no association was found between calcium and vitamin D intake and total, advanced, or high-grade prostate cancer risk, whether for total intake, intake from foods, or intake from supplements, among all male participants or among nonusers of supplemental calcium. No association of calcium or vitamin D intake was seen across racial/ethnic groups. In analyses of food groups, dairy product and total milk consumption were not associated with prostate cancer risk. However, low-/nonfat milk was related to an increased risk and whole milk to a decreased risk of total prostate cancer; after stratification, these effects were limited to localized or low-grade tumors. Although the findings from this study do not support an association between the intakes of calcium and vitamin D and prostate cancer risk, they do suggest that an association with milk consumption may vary by fat content, particularly for early forms of this cancer.

    Full Text Available In Albania, breast cancer is an important cause of death among women, with increasing incidence from 65 cases in 1970, to 400 cases in 2007. This is the first study concerning breast cancer risk factors in Albania. We used a population-based case-control study of 948 women with breast cancer compared with 1019 controls recruited from other hospitals through random selection. Early age at menarche was found to be a significantly strong risk factor during the pre- and postmenopausal groups with OR 10.04 and 12.1, respectively. In addition, nulliparity is associated with higher risk while abortion did not indicate any influence in the multivariate model. The findings from this study have shown that reproductive and menstrual variables are significant predictors of breast cancer risk in Albanian women, as seen in studies of other western countries.

    This study aimed to investigate the effects of Qigong intervention on quality of life (QOL), health-related functioning, and cancer-related symptoms in survivors of nasopharyngeal cancer (NPC). Twenty-five survivors of NPC were included in the experimental group (mean age ± SD: 55.4 ± 7.5 years) and 27 in the control group (mean age ± SD: 58.7 ± 9.5 years). The experimental group underwent a weekly 1.5-hour Qigong training program and an identical home program (three times/week) for six months. The control group received no training. Global health status/QOL, functioning, and cancer-related symptoms were assessed by the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-H&N35 questionnaires before training began, after three months of Qigong training, at the end of the six-month Qigong intervention (i.e., posttest), and six months posttest. Intention-to-treat analysis revealed no statistically (P > 0.05) or clinically significant improvement in global health status/QOL, functioning, or symptoms in either group. The experimental group had 45.8% fewer sense-related (smell and taste) problems (P Qigong intervention. Qigong training resulted in no apparent improvement in health-related QOL, functionality, or cancer-related symptoms in cancer-free survivors of NPC, except for a possible reduction in smell- and taste-related problems.

    Full Text Available Previous studies suggested Ataxia-telangiectasia group D complementing gene (ATDC as an oncogene in many types of cancer. However, its expression and biological functions in non-small cell lung cancer (NSCLC remain unclear. Herein, we investigated its expression pattern in 109 cases of human NSCLC samples by immunohistochemistry and found that ATDC was overexpressed in 62 of 109 NSCLC samples (56.88%. ATDC overexpression correlated with histological type (p<0.0001, tumor status (p = 0.0227 and histological differentiation (p = 0.0002. Next, we overexpressed ATDC in normal human bronchial epithelial cell line HBE and depleted its expression in NSCLC cell lines A549 and H1299. MTT and colony formation assay showed that ATDC overexpression promoted cell proliferation while its depletion inhibited cell growth. Furthermore, cell cycle analysis showed that ATDC overexpression decreased the percentage of cells in G1 phase and increased the percentage of cells in S phase, while ATDC siRNA treatment increased the G1 phase percentage and decreased the S phase percentage. Further study revealed that ATDC overexpression could up-regulate cyclin D1 and c-Myc expression in HBE cells while its depletion down-regulated cyclin D1 and c-Myc expression in A549 and H1299 cells. In addition, ATDC overexpression was also associated with an increased proliferation index, cyclin D1 and c-Myc expression in human NSCLC samples. Further experiments demonstrated that ATDC up-regulated cyclin D1 and c-Myc expression independent of wnt/β-catenin or p53 signaling pathway. Interestingly, ATDC overexpression increased NF-κB reporter luciferase activity and p-IκB protein level. Correspondingly, NF-κB inhibitor blocked the effect of ATDC on up-regulation of cyclin D1 and c-Myc. In conclusion, we demonstrated that ATDC could promote lung cancer proliferation through NF-κB induced up-regulation of cyclin D1 and c-Myc.

    Full Text Available Abstract Background Breast cancer is the most common form of malignancy affecting women worldwide. It is also the leading cancer in females in Cyprus, with approximately 400 new cases diagnosed annually. It is well recognized that genetic variation as well as environmental factors modulate breast cancer risk. The main aim of this study was to assess the strength of associations between recognized risk factors and breast cancer among Cypriot women. This is the first epidemiological investigation on risk factors of breast cancer among the Cypriot female population. Methods We carried out a case-control study, involving 1,109 breast cancer patients and a group of 1,177 controls who were recruited while participating in the National screening programme for breast cancer. Information on demographic characteristics and potential risk factors were collected from both groups during a standardized interview. Logistic regression analysis was used to assess the strength of the association between each risk factor and breast cancer risk, before and after adjusting for the possible confounding effect of other factors. Results In multivariable models, family history of breast cancer (OR 1.64, 95% CI 1.23, 2.19 was the strongest predictor of breast cancer risk in the Cypriot population. Late menarche (OR 0.64, 95% CI 0.45, 0.92 among women reaching menarche after the age of 15 vs. before the age of 12 and breastfeeding (OR 0.74, 95% CI 0.59, 0.92 exhibited a strong protective effect. In the case of breastfeeding, the observed effect appeared stronger than the effect of pregnancy alone. Surprisingly, we also observed an inverse association between hormone replacement therapy (HRT although this may be a product of the retrospective nature of this study. Conclusion Overall the findings of our study corroborate with the results of previous investigations on descriptive epidemiology of risk factors for breast cancer. This investigation provides important background

    AIM To test the hypothesis that Helicobacter pylori eradication alone can reduce the incidence of gastric cancer in a subgroup of individuals with an increased risk for this fatal disease.METHODS It is a prospective, randomized,double-blind, placebo-controlled multinational multicenter trial. Men between 55 and 65 years of age with a gastric cancer phenotype of Helicobacterpylori gastritis are randomized to receive a 7-day course of omeprazole 2 × 20 mg,clarithromycin 2 × 500 mg, and amoxicillin 2 ×lg for 7 days, or omeprazole2 × 20mg plusplacebo. Follow - up endoscopy is scheduled 3months after therapy, and thereafter in one-year intervals. Predefined study endpoints are gastric cancer, precancerous lesions (dysplasia, adenoma), other cancers, anddeath.RESULTS Since March 1998, 1524 target patients have been screened, 279 patients (18.3%) had a corpus-dominant type of H.pylori gastritis, and 167 of those were randomized (58.8%). In the active treatment group (n -- 86), H. pylori infection infection was cured in 88.9% of patients. Currently, thecumulative follow-up time is 3046 months (253.8patient-years, median follow-up 16 months). So far, none of the patients developed gastric cancer or any precancerous lesion. Three(1.8%) patients reached study endpoints other than gastric cancer.CONCLUSION Among men between 55 and 65years of age, the gastric cancer phenotype of H.pylori gastritis appears to be more common than expected. Further follow- up and continuing recruitment are necessary to fulfil the main aim of the study.

    This study was performed to find out whether copper, zinc, manganese, selenium and iron concentrations in the cancerous and normal stomach tissues of the patients with stomach cancer vary within the malignant stages and Borrmann classification or not, and to investigate the interaction of copper, zinc, manganese, selenium and iron concentrations in blood of these patients. Copper concentration in cancerous tissues was not statistically significant as compared with normal tissues. Plasma and whole blood copper concentration of Stage IV showed a significant higher level than that of stage I. Zinc concentration in cancerous tissues was not statistically significant as compared with normal tissues. Selenium concentration in cancerous tissues showed a statistically significant high level as compared with that in normal tissues. Plasma selenium concentration of Stage III showed a significant lower level than that of stage I. Iron concentration in cancerous tissues showed a significantly lower level than that in normal tissues at stage IV. Whole blood iron concentration was low levels in proportion to the progress of stomach cancer. The correlation of selenium concentration between in cancerous tissues and in whole blood of these patients was significant with the correlation coefficient of 0.340. The correlation of iron concentration between in cancerous tissues and in whole blood of these patients was significant with the correlation coefficient of 0.423. The correlation between iron concentration in cancerous tissues and hemoglobin concentration in whole blood of these patients was significant with the correlation coefficient of 0.361.

    Result of study about local effect of hyperthermia in combination with radiotherapy for superficial tumors was reported. The irradiation was more than 90% isodose for lesion, and total dose was 60 Gy in cases with anamnesis and 40-50 Gy and without anamnesis at a rate of five times a week and 2 Gy at one time. Hyperthermia was carried out four times; once a week, at 42.5 degrees on tumor side edge, and for 40 minutes. Total 53 cases (neck lymph node metastasis 30 cases, relapse breast cancer 11, advanced breast cancer 1, other superficial tumor 11) were divided into 2 groups. Radiotherapy without hyperthermia (group R) was 27 cases, radiotherapy with hyperthermia (group H) was 26 cases. CR and CR+PR within 2 months after treatment were as follows: Group R: 50%, 85%, Group H: 64%, 100%. The CR+PR was superior in group H (p=0.0497). The CR at maximum effect after treatment was 65% of group R and 86% of group H (p=0.17). The local control rate after CR was not different in both groups. (K.H.)

    Objective:The aim of our study was to investigate the prognosis of obese breast cancer patients. Methods:This study was conducted on a total of 317 breast cancer patients who were histopathological y and clinical y diagnosed at the General Hospital of Shenyang Military Region (China) from 2004 to 2006. Clinical data including height, weight, age at diagnosis, tumor size, lymph node status, menopausal status, family history of cancer and hormone receptor status were col-lected. Log-rank test was performed to compare the disease free survival (DFS) and overal survival (OS). Cox proportional hazards regression analysis was conducted to make multivariate analysis. The Chi square test was used to compare the clinical features among normal weight group, overweight group, and obese group. Results:Obesity was an independent prognostic factor for DFS (P=0.022) and OS (P=0.032) in breast cancer patients. In the stratified analysis based on the hormone receptor status, obesity was independently associated with OS in patients with negative ER/PR (P=0.002), but such association was not observed in patients with positive hormone receptors. Obesity was also associated with lymph node status (P=0.001) and smoking (P=0.009). Conclusion:Obesity is associated with poor DFS and OS in patients with breast cancer. Therefore, maintaining normal weight may benefit breast cancer patients.

    Soy and its constituents have been shown in many in vivo and in vitro studies and in some epidemiological studies to have anti-cancer effects. Some soy constituents, however, also stimulate cell proliferation, which has raised concerns in promoting soy intake among breast cancer survivors. To investigate whether soy intake may be associated with breast cancer survival, we evaluated data from a cohort of 1459 breast cancer patients who participated in the Shanghai Breast Cancer Study between 1996 and 1998. Usual soy food intake was assessed using a validated food frequency questionnaire at baseline. The median follow-up time for this cohort of women was 5.2 years. We found that soy intake prior to cancer diagnosis was unrelated to disease-free breast cancer survival (adjusted hazard ratio [HR]=0.99, 95% confidence interval [CI], 0.73-1.33 for the highest tertile compared to the lowest tertile). The association between soy protein intake and breast cancer survival did not differ according to ER/PR status, tumor stage, age at diagnosis, body mass index (BMI), waist to hip ratio (WHR), or menopausal status. Additionally, the soy-survival association did not appear to vary according to XbaI or PvuII polymorphisms in ER-alpha, or C(14206)T, G(25652)A, or A(50766)G polymorphisms in ER-beta. These data suggest that soyfoods do not have an adverse effect on breast cancer survival.

    Background and Objectives:Lung cancer is the most common cancer and cancer related cause of death worldwide. However, the association between sleep duration and incident lung cancer has not been investigated in a prospective cohort study. Methods:We prospectively examined the association between sleep duration and incident lung cancer in a cohort of 21,026 United States (US) male physicians. Self-reported sleep duration was ascertained during 2002 annual follow-up questionnaire. Incident lung cancer was ascertained through yearly follow-up questionnaires. Cox regression was used to estimate relative risk of incident lung cancer. Results:hTe average age at baseline was 68.3±8.8 yr. During a mean follow up of 7.5 (±2.2) yr, 150 cases of lung cancer occurred. Using 7 h of sleep as the reference group, multivariable adjusted hazard ratios (95%CI) for lung cancer were 1.18 (0.77-1.82), 1.0 (ref), and 0.97 (0.67-1.41) from lowest to the highest category of sleep duration (P for quadratic trend 0.697), respectively. In a secondary analysis, smoking status did not modify the sleep duration-lung cancer association (P=0.78). hTere was no evidence for an interaction between sleep duration and sleep apnea on the risk of lung cancer either (P=0.65). Conclusions:Our data failed to show a higher risk of lung cancer in association with altered sleep duration among US male physicians.

    EZH2, a core member of the Polycomb Repressor Complex 2 (PRC2), mediates transcriptional silencing by catalyzing the trimethylation of histone 3 lysine 27 (H3K27), which plays key roles in cancer initiation and progression. Here, we investigated the expression pattern and biological roles of EZH2 in tongue tumorigenesis by loss-of-function assays using small interference RNA and EZH2 inhibitor DZNep. Also we determined the therapeutic efficiency of DZNep against tongue cancer in vivo. We found that aberrantly overexpressed EZH2 was associated with pathological grade, cervical nodes metastasis and Ki-67 expression in tongue cancers. Elevated EZH2 correlated with shorter overall survival and showed significant and independent prognostic importance in patients with tongue cancer. Both genetic and pharmacological depletion of EZH2 inhibited cell proliferation, migration, invasion and colony formation and decreased CD44+ subpopulation probably in part through modulating p16, p21 and E-caherin. Moreover, DZNep enhanced the anticancer effects of 5-Fluorouracil. Furthermore, intratumoral EZH2 inhibition induced by DZNep intraperitoneal administration significantly attenuated tumor growth in a tongue cancer xenograft model. Taken together, our results indicate that EZH2 serves as a key driver with multiple oncogenic functions during tongue tumorigenesis and a new biomarker for tongue cancer diagnosis and prognostic prediction. These findings open up possibilities for therapeutic intervention against EZH2 in tongue cancer.

    Full Text Available Abstract Background Aim of this longitudinal study was to investigate the sensitivity to change of the Swedish Self Evaluation of Communication Experiences after Laryngeal Cancer questionnaire (the S-SECEL, addressing communication dysfunction in patients treated for laryngeal cancer. Previous studies have highlighted the need for more specific questionnaires for this purpose. Methods 100 patients with Tis-T4 laryngeal cancer were included prior to treatment onset. Patients answered four questionnaires at six occasions during one year; the S-SECEL, the European Organisation for Research and Treatment of Cancer (EORTC Core Quality of Life Core Questionnaire (QLQ-C30 supplemented by the Head and Neck cancer module (QLQ-H&N35 and the Hospital Anxiety and Depression (HAD scale. In addition, performance status was assessed. Differences within groups were tested with the Wilcoxon paired signed ranks test and between-group analyses were carried out using the Mann-Whitney U test. Magnitude of group differences was analyzed by means of effect sizes. Results The S-SECEL was well accepted with a response rate of 76%. Communication dysfunction increased at 1 month, followed by a continuous decrease throughout the year. Changes were statistically significant at most measurement, demonstrating the sensitivity of the S-SECEL to changes in communication over time. The S-SECEL and the EORTC QLQ-C30 with the QLQ-H&N35 demonstrated similar results; however the S-SECEL was more sensitive regarding communication dysfunction. The largest changes were found in the most diagnose specific items concerning voice and speech. Conclusion The S-SECEL was investigated in the largest Scandinavian longitudinal study concerning health-related quality of life (HRQL in laryngeal cancer patients. The questionnaire was responsive to change and showed convergent results when compared to established HRQL questionnaires. Our findings also indicate that the S-SECEL could be a more

    Motor electricity consumption is influenced by many factors including: motor efficiency, motor speed controls, power supply quality, harmonics, systems oversizing, distribution network, mechanical transmission system, maintenance practices, load management and cycling, and the efficiency of the end-use device (e.g. fan, pump, etc.). Due to their importance, an overview of these factors is presented in this report. This study also describes the electricity use in the industrial and tertiary sectors and the electricity consumption associated with the different types of electric motors systems in the Member States of the European Union, as well as estimated future evolution until 2010. The studies for individual countries were carried out by the different partners of the motors study group at a previous stage. The study has found that there is a lack of accurate information about the motor electricity consumption, installed motor capacity and the motor market in almost all the European Union countries and only some general statistical sources are available. There is little field data, which is mainly available in Denmark, France, Italy and the Netherlands. Due to this lack of primary information, some common assumptions were made, based on the experience of the members of the study group. This lack of end-use characterisation data shows the need for improvement from the point of view of current knowledge. It is therefore recommended that further research is undertaken to arrive at more accurate figures. These could be the basis for a better understanding for motor use in practice and - as a consequence - for a more precise appraisal of potentials and barriers to energy efficiency. (orig.)

    From January 1988 to December 1994, 66 consecutive blood culture isolates of viridans group streptococci collected from febrile neutropenic cancer patients were tested for antimicrobial susceptibilities by the agar dilution method. The antibiotics studied were erythromycin, clarithromycin, roxithromycin, dirithromycin, azithromycin, josamycin, diacetyl-midecamycin, spiramycin, and quinupristin-dalfopristin. A total of 26 (39.4%) strains were resistant to erythromycin with an MIC range of 0.5 to > 128 micrograms/ml. The strains were classified into three groups according to their penicillin susceptibility: 42 (63.6%) were susceptible, 8 (12.1%) were intermediately resistant, and 16 (24.3%) were highly resistant. The percentages of erythromycin-resistant strains in each group were 23.8, 62.5, and 68.8%, respectively. Streptococcus mitis was the species most frequently isolated (83.3%) and showed the highest rates of penicillin (40%) and erythromycin (43.6%) resistance. MICs of all macrolide antibiotics tested and of quinupristin-dalfopristin were higher for penicillin-resistant strains than for penicillin-susceptible strains. All macrolide antibiotics tested had cross-resistance to erythromycin, which was not observed with quinupristin-dalfopristin. Our study shows a high rate of macrolide resistance among viridans group streptococci isolated from blood samples of neutropenic cancer patients, especially those infected with penicillin-resistant strains. These findings make macrolides unsuitable prophylactic agents against viridans group streptococcal bacteremia in this patient population.

    The most common cancer treatments currently available are radio- and chemo-therapy. These therapies have, however, drawbacks, such as, the reduction in quality of life and the low efficiency of radiotherapy in cases of multiple metastases. To lessen these effects, we have encapsulated an anti-cancer...... drug into a biocompatible matrix. In-vitro assays indicate that this bio-nanocomposite is able to interact and cause morphological changes in cancer cells. Meanwhile, no alterations were observed in monocytes and fibroblasts, indicating that this system might carry the drug in living organisms...

    Full Text Available Abstract Background National cancer policies identify the improvement of care coordination as a priority to improve the delivery of health services for people with cancer. Identification of the current barriers to effective cancer care coordination is needed to drive service improvement. Methods A qualitative study was undertaken in which semi-structured individual interviews and focus groups were conducted with those best placed to identify issues; patients who had been treated for a range of cancers and their carers as well as health professionals involved in providing cancer care. Data collection continued until saturation of concepts was reached. A grounded theory influenced approach was used to explore the participants' experiences and views of cancer care coordination. Results Overall, 20 patients, four carers and 29 health professionals participated. Barriers to cancer care coordination related to six aspects of care namely, recognising health professional roles and responsibilities, implementing comprehensive multidisciplinary team meetings, transitioning of care: falling through the cracks, inadequate communication between specialist and primary care, inequitable access to health services and managing scarce resources. Conclusions This study has identified a number of barriers to coordination of cancer care. Development and evaluation of interventions based on these findings is now required.

    To investigate the application of human finger nails in the diagnosis of cancer, Fourier transform infrared (FTIR) spectroscopy was employed to study the finger nails from some normal people and some with esophagus cancer and others with an operation for curing esophagus cancer five months ago. The results showed that there are obvious differences between FTIR spectra in them in spectral parameters such as frequency, intensity and band shape etc. The changes in the phosphate symmetric stretching vibration v(s) (PO2-) and asymmetric stretching vibration v(a)s(PO2-) modes are uniform, the v(s) (PO2-) and v(a)s(PO2-) absorption peaks of cancerous ones shift to high wave number compared with those of normal people, while those with operation shift to low wave number compared with those of cancerous ones. The C-O stretching vibration mode of protein located at 1 164 cm(-1) is composed of three absorption peaks located at 1 173.3, 1 158.0 and 1 151.1 cm(-1) respectively, meanwhile, the intensities and the wave numbers of the three peaks of cancerous ones all increase compared with normal people. The wave numbers of amide I and amide II of cancerous ones are both lower than those of normal people, while those with operation are between the cancerous ones and normal people, which suggest that the contents of protein and alpha-helix in finger nails of normal people, cancerous ones and the ones with operation are discriminative. The peak of bending vibration delta(CH2) mode of CH2 groups of protein lipid of cancerous ones shifts to high wave number slightly and the intensity of the peak weakens compared with that of normal people, which indicate that the methylene chain in the finger nails membrane lipids of cancerous ones is more ordered than that of normal people. Nevertheless, the peak of stretching vibration v(s) (CH2) of cancerous ones is lower than that of normal people, while that of the ones with operation is between cancerous ones and normal ones. As a result, the

    The principal cause of death in cancer involves tumor progression and metastasis. Since only a small proportion of the primary tumor cells, cancer stem cells (CSCs), which are the most aggressive, have the capacity to metastasize and display properties of stem cells, it is imperative to characterize the gene expression of diagnostic markers and to evaluate the drug sensitivity in the CSCs themselves. Here, we have examined the key genes that are involved in the progression of colorectal cancer and are expressed in cancer stem cells. Primary cultures of colorectal cancer cells from a patient's tumors were studied using the flow cytometry and cytological methods. We have evaluated the clinical and stem cell marker expression in these cells, their resistance to 5-fluorouracil and irinotecan, and the ability of cells to form tumors in mice. The data shows the role of stem cell marker Oct4 in the resistance of primary colorectal cancer tumor cells to 5-fluorouracil.

    2007-01-01

    BACKGROUND: Although mechanisms for detection of short-term complications after blood transfusions are well developed, complications with delayed onset, notably transmission of chronic diseases such as cancer, have been difficult to assess. Our aim was to investigate the possible risk of cancer...... transmission from blood donors to recipients through blood transfusion. METHODS: We did a register-based retrospective cohort study of cancer incidence among patients who received blood from donors deemed to have a subclinical cancer at the time of donation. These precancerous donors were diagnosed...... with a cancer within 5 years of the donation. Data from all computerised blood bank registers in Sweden and Denmark gathered between 1968 and 2002 were merged into a common database. Demographic and medical data, including mortality and cancer incidence, were ascertained through linkages with nationwide...

    As the interest in graphic medicine grows, health communicators have started engaging readers with compelling visual and textual accounts of health and illness, including via comic books. One context where comics have shown promise is cancer communication. This brief report presents an early example of graphic medicine developed by the American Cancer Society. "Ladies … Wouldn't It Be Better to Know?" is a comic book produced in the 1960s to provide the public with lay information about the Pap test for cervical cancer prevention and detection. An analysis of a key narrative attribute, plot development, illustrates the central role that perceived barriers played in this midcentury public health message, a component that remains a consideration of cancer communication design today. This case study of an early graphic narrative identifies promising cancer message features that can be used to address and refute barriers to cervical cancer screening and connects contemporary research with historical efforts in public health communication.

  10. Cancer Mortality in People Treated with Antidepressants before Cancer Diagnosis: A Population Based Cohort Study.

    Full Text Available Depression is common after a cancer diagnosis and is associated with an increased mortality, but it is unclear whether depression occurring before the cancer diagnosis affects cancer mortality. We aimed to study cancer mortality of people treated with antidepressants before cancer diagnosis.We conducted a population based cohort study of all adults diagnosed with cancer between January 2003 and December 2010 in Denmark (N = 201,662. We obtained information on cancer from the Danish Cancer Registry, on the day of death from the Danish Civil Registry, and on redeemed antidepressants from the Danish National Prescription Registry. Current users of antidepressants were defined as those who redeemed the latest prescription of antidepressant 0-4 months before cancer diagnosis (irrespective of earlier prescriptions, and former users as those who redeemed the latest prescription five or more months before cancer diagnosis. We estimated an all-cause one-year mortality rate ratio (MRR and a conditional five-year MRR for patients who survived the first year after cancer diagnosis and confidence interval (CI using a Cox proportional hazards regression model. Overall, 33,111 (16.4% patients redeemed at least one antidepressant prescription in the three years before cancer diagnosis of whom 21,851 (10.8% were current users at the time of cancer diagnosis. Current antidepressant users had a 32% higher one-year mortality (MRR = 1.32, 95% CI: 1.29-1.35 and a 22% higher conditional five-year mortality (MRR = 1.22, 95% CI: 1.17-1.26 if patients survived the first year after the cancer diagnosis than patients not redeeming antidepressants. The one-year mortality was particularly high for patients who initiated antidepressant treatment within four months before cancer diagnosis (MRR = 1.54, 95% CI: 1.47-1.61. Former users had no increased cancer mortality.Initiation of antidepressive treatment prior to cancer diagnosis is common and is associated with an increased

    The prevalence of cancer is not well established and probably underestimated in long-stay psychiatric inpatients. Psychiatric patients do not have the same access for cancer screening and care. Therapeutic decision-making is a real ethical problem. In this context, access to medical care should be provided by the establishment of guidelines and/or recommendations for this specific population. The aim of our study was to assess how cancer was managed among long term psychiatric inpatients. For this pilot study, we used a mixed methodology: a quantitative part with a retrospective chart review of cancer patients in a psychiatric institution and a qualitative part based on semi-structured interviews with psychiatrists with discourse analysis. Delay in cancer diagnosis can be explained by communication and behavior disorders, inadequate screening, and additional tests often refused by patients. Compliance and ethical issues (i.e. obtaining informed consent) are many pitfalls to optimal cancer care that should be explored in further research.

    Objective: Caudal epidural analgesia has become very common analgesic technique in paediatric surgery. Add-ing tramadol to bupivacaine for caudal injection prolongs duration of analgesia with minimal side effects. The aim of the study was to investigate the different effects of caudal bupivacaine versus bupivacaine with thamadol for postoperative analgesia in paediatric cancer patients. Methods: A prospective randomized controlled trial was conducted over 40 paediatric cancer pa-tients who were recruited from Children Cancer Hospital of Egypt (57357 Hospital). Patients were randomized into 2 groups: bupivacaine group (group B, 20 patients) to receive single shot caudal block of 1 mL/kg 0.1875% bupivacaine; tramadol group (group T, 20 patients) prepared as group B with the addition of 1 mg/kg caudal tramadol. Results: The mean duration of analgesia was significantly longer among group T than group B [(24 ± 13.7) hours versus (7 ± 3.7) hours respectively with P = 0.001]. Group T showed a significantly lower mean FLACC score than group B (2.2 ± 0.9 versus 3.6 ± 0.6 with P = 0.002). The difference in FLACC score was comparable on arrival, and after 2 and 4 hours. At 8 and 12 hours the group B recorded significantly higher scores (P = 0.002 and 0.0001 respectively). There were no significant differences between the groups as regards sedation score [the median in both groups was 1 (0–1) with P value = o.8]. No one developed facial flush or pruritis. Conclusion: Caudal injection of low dose tramadol 1 mg/kg with bupivacaine 0.1875% is proved to be effective, long standing technique for postoperative analgesia in major paediatric cancer surgery and almost devoid of side effect.

    2015-01-01

    Objective: To observe the clinical therapeutic effect of docetaxel, prednisone and bevacizunab in the treatment of hormone refractory prostate cancer. Methods:A total of 100 patients with hormone refractory prostate cancer were selected and randomly divided into 2 groups: chemotherapy group and combined group, 50 cases for each. Patients in chemotherapy group were given oral administration of hexadecadrol, 8 mg/d, intravenous drip of docetaxel, 40 mg/m2, orally taking of prednisone, 5 mg/d. Patients in combined group was added with bevacizumab, 5 mg/kg (which was diluted to 100 mL of chloride sodium injection) based on regimen of chemotherapy group. All patients were followed up every month after the end of treatment for recording reoccurrence, metastasis and deaths. Additionally, serum prostate-speciifc antigen (PSA), free prostate-speciifc antigen (fPSA)/total prostate-speciifc antigen (tPSA) before and after chemotherapy, prostate volume, maximum flow rate, the quality of life (QOL) were measured and evaluated. The progression-free survival (PFS) and the overall survival (OS) were analyzed by Kaplan-Meier method. Results: After treatment, the level of PSA in combined group was lower than that in chemotherapy group (P0.05). The median PFS and OS in combined group were 13 months and 20 months, respectively, higher than those in chemotherapy group (10 months and 17 months) (P0.05). Conclusion: Docetaxel combined with Bevacizunab can prolong the survival time of patients with hormone refractory prostate cancer, but its therapeutic effect still needs to be further veriifed. Additionally, with the in-depth of studies on hormone refractory prostate cancer in translational medicine, immunotherapy, targeted therapy, individualized treatment and multidrug therapy will surely become the research hotspot for hormone refractory prostate cancer.

    2012-02-01

    Full Text Available Abstract Background Normal bronchial tissue expression of GRPR, which encodes the gastrin-releasing peptide receptor, has been previously reported by us to be associated with lung cancer risk in 78 subjects, especially in females. We sought to define the contribution of GRPR expression in bronchial epithelia to lung cancer risk in a larger case-control study where adjustments could be made for tobacco exposure and sex. Methods We evaluated GRPR mRNA levels in histologically normal bronchial epithelial cells from 224 lung cancer patients and 107 surgical cancer-free controls. Associations with lung cancer were tested using logistic regression models. Results Bronchial GRPR expression was significantly associated with lung cancer (OR = 4.76; 95% CI = 2.32-9.77 in a multivariable logistic regression (MLR model adjusted for age, sex, smoking status and pulmonary function. MLR analysis stratified by smoking status indicated that ORs were higher in never and former smokers (OR = 7.74; 95% CI = 2.96-20.25 compared to active smokers (OR = 1.69; 95% CI = 0.46-6.33. GRPR expression did not differ by subject sex, and lung cancer risk associated with GRPR expression was not modified by sex. Conclusions GRPR expression in non-cancerous bronchial epithelium was significantly associated with the presence of lung cancer in never and former smokers. The association in never and former smokers was found in males and females. Association with lung cancer did not differ by sex in any smoking group.

    2012-04-01

    Full Text Available Abstract Background A significant number of smokers would like to stop smoking. Despite the demonstrated efficacy of pharmacological smoking cessation treatments, many smokers are unwilling to use them; however, they are inclined to try alternative methods. Hypnosis has a long-standing reputation in smoking cessation therapy, but its efficacy has not been scientifically proven. We designed this randomised controlled trial to evaluate the effects of group hypnosis as a method for smoking cessation, and we will compare the results of group hypnosis with group relaxation. Methods/Design This is a randomised controlled trial (RCT to compare the efficacy of a single session of hypnosis with that of relaxation performed in groups of 8-15 smokers. We intend to include at least 220 participants in our trial. The inclusion criteria include smoking at least 5 cigarettes per day, not using other cessation methods and being willing to quit smoking. The intervention is performed by a trained hypnotist/relaxation therapist. Both groups first receive 40 min of mental preparation that is based on motivational interviewing. Then, a state of deep relaxation is induced in the hypnosis condition, and superficial relaxation is induced in the control condition. Suggestions are made in the hypnosis condition that aim to switch the mental self-image of the participants from that of smokers to that of non-smokers. Each intervention lasts for 40 min. The participants also complete questionnaires that assess their smoking status and symptoms of depression and anxiety at baseline, 2 weeks and 6 months post-intervention. In addition, saliva samples are collected to assess cotinine levels at baseline and at 6 months post-intervention. We also assess nicotine withdrawal symptoms at 2 weeks post-intervention. Discussion To the best of our knowledge, this RCT is the first to test the efficacy of group hypnosis versus group relaxation. Issues requiring discussion in the outcome

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

    The Multiethnic Cohort epidemiology study has clearly demonstrated that, compared to Whites and for the same number of cigarettes smoked, African Americans and Native Hawaiians have a higher risk for lung cancer whereas Latinos and Japanese Americans have a lower risk. Acrolein and crotonaldehyde are two important constituents of cigarette smoke which have well documented toxic effects and could play a role in lung cancer etiology. Their urinary metabolites 3-hydroxypropylmercapturic acid (3-HPMA) and 3-hydroxy-1-methylpropylmercapturic acid (HMPMA), respectively, are validated biomarkers of acrolein and crotonaldehyde exposure. We quantified levels of 3-HPMA and HMPMA in the urine of more than 2200 smokers from these five ethnic groups, and also carried out a genome wide association study using blood samples from these subjects. After adjusting for age, sex, creatinine, and total nicotine equivalents, geometric mean levels of 3-HPMA and HMPMA were significantly different in the five groups (P acrolein and crotonaldehyde may be involved in lung cancer etiology, and that their divergent levels may partially explain the differing risks of Native Hawaiian and Latino smokers. No strong signals were associated with 3-HPMA in the genome wide association study, suggesting that formation of the glutathione conjugate of acrolein is mainly non-enzymatic, while the top significant association with HMPMA was located on chromosome 12 near the TBX3 gene, but its relationship to HMPMA excretion is not clear.

    Full Text Available Overweight and obesity are a major concern in young adults. Technology has been integrated into many weight loss interventions; however little is known about the use of this technology in young adults. The purpose of this study was to explore through focus group sessions the opinions of young adults on the use of technology for weight loss. A total of 17 young adults, between 18 and 25 years of age, participated in three focus group sessions. Major results indicated that young adults have very little knowledge on the use of Smartphone technology for weight loss but would like to use this type of technology to help them lose weight. Results also indicated that young adults struggle to make healthy food choices and have priorities that outweigh exercise and they need support and guidance to make better decisions. In conclusion, young adults would be open to using Smartphone technology for weight loss but also need feedback and guidance to help make healthy decisions.

  1. An ethnography of reading in a spiritist study group

    Bernardo Lewgoy

    Full Text Available As a religion, Kardecism confers fundamental importance to the study of its own body of literature, understood as the complement to religious revelation. Based upon ethnographic research in a traditional middle-class Kardecist centre in Porto Alegre, this article examines some ways through which the Kardecists, structured in small groups, interact with this written tradition. The group is fundamental in forming a spiritist identity for two reasons: firstly, it delimits internal alliances, whether or not these are translated into differences in doctrinal views. Secondly, it is one of the spaces in which the spiritist orator is formed by learning to make use of formulas extracted from a specific repertoire. Inspired by the discussions on orality and literacy and by the recent proposal for an ethnography of reading (Boyarin 1993, I aim to show that, if the spiritist speech is constructed as orality supported by texts, there are also very important informal dimensions to be considered which contextualize and actualize these group’s relation with sacred texts.

  3. Accountable Metadata-Hiding Escrow: A Group Signature Case Study

    Directory of Open Access Journals (Sweden)

    Kohlweiss Markulf

    2015-06-01

    Full Text Available A common approach to demands for lawful access to encrypted data is to allow a trusted third party (TTP to gain access to private data. However, there is no way to verify that this trust is well placed as the TTP may open all messages indiscriminately. Moreover, existing approaches do not scale well when, in addition to the content of the conversation, one wishes to hide one’s identity. Given the importance of metadata this is a major problem. We propose a new approach in which users can retroactively verify cryptographically whether they were wiretapped. As a case study, we propose a new signature scheme that can act as an accountable replacement for group signatures, accountable forward and backward tracing signatures.

    This is an interim report discussing possible guidelines for the assessment and evaluation of projects developing speech and language systems. It was prepared at the request of the European Commission DG XIII by an ad hoc study group, and is now being made available in the form in which it was submitted to the Commission. However, the report is not an official European Commission document, and does not reflect European Commission policy, official or otherwise. After a discussion of terminology, the report focusses on combining user-centred and technology-centred assessment, and on how meaningful comparisons can be made of a variety of systems performing different tasks for different domains. The report outlines the kind of infra-structure that might be required to support comparative assessment and evaluation of heterogenous projects, and also the results of a questionnaire concerning different approaches to evaluation.

    Olivier Mesly

    2013-05-01

    Full Text Available This paper rests largely on the works of Mesly (1999 to 2012. It argues that the phenomenon of perceived predation as a functional behavioural phenomenon is subjected to certain limits, a finding based on studies performed on 19 different groups spread over a four-year span. It also finds a constant of k = 1.3 which reflects the invariant nature of perceived predation. These findings add to the theory of financial predation which stipulates that financial predators operate below the limits of detection pertaining to their customers (and market regulators. They are experts at minimizing the perception that clients could have that they are after their money, causing them financial harm, by surprise (perceived predation. Understanding the narrow range in which financial predators operate is setting the grounds to offer better protection to investors and to implementing better control and punitive measures.

    2013-02-01

    Cancer is a disease of unregulated cell growth and survival, and tumors reprogram biochemical pathways to aid these processes. New capabilities in the computational and bioanalytical characterization of metabolism have now emerged, facilitating the identification of unique metabolic dependencies that arise in specific cancers. By understanding the metabolic phenotype of cancers as a function of their oncogenic profiles, metabolic engineering may be applied to design synthetically lethal therapies for some tumors. This process begins with accurate measurement of metabolic fluxes. Here we review advanced methods of quantifying pathway activity and highlight specific examples where these approaches have uncovered potential opportunities for therapeutic intervention.

    Full Text Available Abstract Background Tobacco smoke exposure may be associated with increased breast cancer risk, although the evidence supporting the association is inconclusive. We conducted a case-control study in Delaware, incorporating detailed exposure assessment for active and secondhand smoke at home and in the workplace. Methods Primary invasive breast cancer cases diagnosed among female Delaware residents, ages 40–79, in 2000–2002 were identified through the Delaware cancer registry (n = 287. Delaware drivers license and Health Care Finance Administration records were used to select age frequency-matched controls for women Results A statistically significant increased risk of breast cancer was observed for ever having smoked cigarettes (odds ratio = 1.43, 95% confidence interval = 1.03–1.99. However, there was no evidence of a dose-response relationship between breast cancer risk and total years smoked, cigarettes per day, or pack-years. Neither residential nor workplace secondhand smoke exposure was associated with breast cancer. Recalculations of active smoking risks using a purely unexposed reference group of women who were not exposed to active or secondhand smoking did not indicate increased risks of breast cancer. Conclusion These findings do not support an association between smoking and breast cancer.

    Full Text Available Research investigating frequent sickness absence (3 or more episodes per year is scarce and qualitative research from the perspective of frequent absentees themselves is lacking. The aim of the current study is to explore awareness, determinants of and solutions to frequent sickness absence from the perspective of frequent absentees themselves.We performed a qualitative study of 3 focus group discussions involving a total of 15 frequent absentees. Focus group discussions were audiotaped and transcribed verbatim. Results were analyzed with the Graneheim method using the Job Demands Resources (JD-R model as theoretical framework.Many participants were not aware of their frequent sickness absence and the risk of future long-term sickness absence. As determinants, participants mentioned job demands, job resources, home demands, poor health, chronic illness, unhealthy lifestyles, and diminished feeling of responsibility to attend work in cases of low job resources. Managing these factors and improving communication (skills were regarded as solutions to reduce frequent sickness absence.The JD-R model provided a framework for determinants of and solutions to frequent sickness absence. Additional determinants were poor health, chronic illness, unhealthy lifestyles, and diminished feeling of responsibility to attend work in cases of low job resources. Frequent sickness absence should be regarded as a signal that something is wrong. Managers, supervisors, and occupational health care providers should advise and support frequent absentees to accommodate job demands, increase both job and personal resources, and improve health rather than express disapproval of frequent sickness absence and apply pressure regarding work attendance.

    Our aim was to study the association between country of birth and incidence of gout in different immigrant groups in Sweden. The study population included the whole population of Sweden. Gout was defined as having at least one registered diagnosis in the National Patient Register. The association between incidence of gout and country of birth was assessed by Cox regression, with hazard ratios (HRs) and 95% confidence intervals (95% CI), using Swedish-born individuals as referents. All models were conducted in both men and women, and the full model was adjusted for age, place of residence in Sweden, educational level, marital status, neighbourhood socio-economic status and co-morbidities. The risk of gout varied by country of origin, with highest estimates, compared to Swedish born, in fully adjusted models among men from Iraq (HR 1.82, 95% CI 1.54-2.16), and Russia (HR 1.69, 95% CI 1.26-2.27), and also high among men from Austria, Poland, Africa and Asian countries outside the Middle East; and among women from Africa (HR 2.23, 95% CI 1.50-3.31), Hungary (HR 1.98, 95% CI 1.45-2.71), Iraq (HR 1.76, 95% CI 1.13-2.74) and Austria (HR 1.70, 95% CI 1.07-2.70), and also high among women from Poland. The risk of gout was lower among men from Greece, Spain, Nordic countries (except Finland) and Latin America and among women from Southern Europe, compared to their Swedish counterparts. The increased risk of gout among several immigrant groups is likely explained by a high cardio-metabolic risk factor pattern needing attention.

This study aims to investigate, from the students’ perspective, whether gender medicine has been taught in daily practice during clerkship.Methods: A focus group study was conducted among 29 medical students from Radboud University, Nijmegen, The Netherlands, who had just finished either their internal medicine or surgical clerkships. Data were analyzed in line with the principles of constant comparative analysis.Results: Four focus groups were conducted with 29 participating students. Clinical teachers barely discuss gender differences during students’ clerkships. The students mentioned three main explanatory themes: insufficient knowledge; unawareness; and minor impact. As a result, students feel that they have insufficient competencies to become gender-sensitive doctors.Conclusion: Medical students at our institution perceive that they have received limited exposure to gender-based education after completing two key clinical clerkships. All students feel that they have insufficient knowledge to become gender-sensitive doctors. They suppose that their clinical teachers have insufficient knowledge regarding gender sensitivity, are unaware of gender differences, and the students had the impression that gender is not regarded as an important issue. We suggest that the medical faculty should encourage clinical teachers to improve their knowledge and awareness of gender issues.Keywords: medical education, clerkship, gender, hidden curriculum, clinical teachers

    2014-01-01

    Particulate matter (PM) plays an important role in air pollution, especially in China. European and American researchers conducted several cohort-based studies to examine the potential relationship between PM and lung cancer and found a positive association between PM and lung cancer mortality. In contrast, the results regarding PM and lung cancer risk remain inconsistent. Most of the previous studies had limitations such as misclassification of PM exposure and residual confounders, diminishing the impact of their findings. In addition, prospective studies on this topic are very limited in Chinese populations. This is an important problem because China has one of the highest concentrations of PM in the world and has had an increased mortality risk due to lung cancer. In this context, more prospective studies in Chinese populations are warranted to investigate the relationship between PM and lung cancer.

This randomized controlled crossover pilot study looked at the effects of individual cognitive behavioral therapy for insomnia (IND-CBT-I on sleep in breast cancer survivors.Patients and methods: Twenty-one participants were randomly assigned to either a treatment group (six weekly IND-CBT-I sessions followed by six weeks of follow up or a delayed treatment control group (no treatment for six weeks followed by six weekly IND-CBT-I sessions. Of these, 14 participants completed the pilot study (six in the treatment group and eight in the delayed treatment control group.Results: Self-rated insomnia was significantly improved in the treatment group compared to the waiting period in the delayed treatment control group. The pooled pre–post-IND-CBT-I analyses revealed improvements in self-rated insomnia, sleep quality, and objective measures of sleep.Conclusions: These preliminary results suggest that IND-CBT-I is appropriate for improving sleep in breast cancer survivors. Individual therapy in a clinic or private practice may be a more practical option for this population as it is more easily accessed and readily available in an outpatient setting.Keywords: insomnia, breast cancer, cognitive behavioral therapy

    Objective:To study and investigate the relationship between the serum vascular endothelial growth factor (VEGF), matrix metalloproteinase (MMP), midkine (MK) and recurrence and metastasis after gastric cancer surgery.Methods:A total of 78 patients with recurrence and metastasis after gastric cancer surgery in our hospital from January 212 to June 2015 were selected as Group A, 78 patients without recurrence and metastasis at the same time were selected as Group B and 78 healthy persons were selected as Group C. Then the serum VEGF, MMP and MK levels of the 3 groups were compared. The detection levels of local recurrence, regional lymphatic metastasis and distant metastasis in Group A were also compared, and the relationship between the serum VEGF, MMP, MK and recurrence and metastasis after gastric cancer surgery was analyzed by the Logistic analysis.Results:The serum VEGF, MMP and MK indexes of Group A were all higher than those of Group B and Group C. The levels of Group B and Group C had no significant differences. Meanwhile, in Group A, the detection levels of regional lymphatic metastasis and distant metastasis were all higher than those of patients with local recurrence. According to the Logistic analysis, the above indexes all had close relationship with the recurrence and metastasis after gastric cancer surgery.Conclusions:The serum VEGF, MMP and MK of patients with recurrence and metastasis after gastric cancer surgery show higher expression state, and those indexes all have close relationship with the disease.

    Full Text Available Bone scintigraphies are widely applied for detecting bone metastases. The aim of this study was to investigate distribution features of bone metastases in pulmonary and prostate cancers. Bone scintigraphies were performed in 460 patients with pulmonary cancer and 144 patients with prostate cancer. Patients were divided into three groups according to the total number of bone metastases: few bone metastases, moderate bone metastases, and extensive bone metastases. We compared the distribution of bone metastases in the two cancers, and analyzed the relationship between the distribution of metastatic lesions and their metastatic patterns. A total of 2279 and 2000 lesions of bone metastases were detected in 258 patients with pulmonary cancer and 102 patients with prostate cancer, respectively. In patients with few bone metastases, the distributions of metastatic lesions in the vertebrae (χ2 = 16.0, P = 0.000 and thoracic bones (χ2 = 20.7, P = 0.002 were significantly different between pulmonary and prostate cancers. In cases with moderate bone metastases, the distributions in the vertebrae (χ2 = 6.6, P = 0.010, pelvis (χ2 = 15.1 P = 0.000, and thoracic bones (χ2 = 38.8, P = 0.000 were also significantly different between the two cancers. However, in patients with extensive bone metastases, the distributions were very similar. As the total number of bone metastases increased, their distribution in pulmonary cancer did not noticeably change, but the distribution in the vertebrae and thoracic bones of prostate cancer patients significantly changed. Accordingly, the distribution characteristics of bone metastases differed in pulmonary and prostate cancers, mainly in the early stages of metastasis.

    Objectives First objective was better understanding of the indications of chemotherapy in elderly with advanced cancer, tolerability and toxicity of chemotherapy in this age group. The second objective was to define current practice in chemotherapy for elderly people with advanced cancer for a selected group of patients treated in Institute of Oncology Bucharest (IOB). Materials and Methods The study makes a clinical analysis of medical records of 27 patients from the archive of Institute of Oncology Bucharest treated by the same doctor. Patients were selected according to: age ≥ 65 years, ECOG performance status 0–1, normal blood counts and blood biochemistry, histological confirmation of the diagnosis of cancer, patients should received at least 3 cycles of chemotherapy. We extract characteristics of the patients to see if they were a homogeneous group of patients and to compare them with data from the literature. Overall survival was calculated by the Kaplan Meyer curve. Results 295 patients more then 65 years were treated in our site in 2 years 2011, 2012. 93 patients received chemotherapy and only 27 patients were enrolled in this study following inclusion criteria. Common sites of cancer were lung and breast. The most used cytostatics for lung cancer was gemcitabine and carboplatine and cyclophosphamide, metotrexat and 5 fluorouracil for breast cancer. Toxicity was mild with the prevalence of hematologic toxicity. Overall survival without taking into account the type of cancer was 27.7 month. Conclusions For selected patients, chemotherapy was well tolerated and appears to prolong survival regardless of the location of cancer. The relatively small number of elderly patients who received chemotherapy is probably due to lack of compliance to treatment, the increased number of co-morbidities and evaluation of performance status only by the ECOG index known not to be good enough to establish the indication of chemotherapy.

    2012-02-01

    Pancreatic ductal adenocarcinoma is one of the most difficult malignancies to diagnose and treat. The aim of this article is to review how tumor markers can aid the diagnosis and management of patients with this malignancy. The most widely used and best validated marker for pancreatic cancer is CA 19-9. Inadequate sensitivity and specificity limit the use of CA 19-9 in the early diagnosis of pancreatic cancer. In non-jaundiced patients, however, CA 19-9 may complement other diagnostic procedures. In patients with resectable pancreatic cancer, presurgical and postresection CA 19-9 levels correlate with overall survival. In advanced disease, elevated pretreatment levels of CA 19-9 are associated with adverse patient outcome and thus may be combined with other factors for risk stratification. Most, but not all, reports indicate that serial levels of CA 19-9 correlate with response to systemic therapy. Use of CA 19-9 kinetics in conjunction with imaging is therefore recommended in monitoring therapy. Although several potential serum and tissue markers for pancreatic cancer are currently undergoing evaluation, none are sufficiently validated for routine clinical use. CA 19-9 thus remains the serum pancreatic cancer marker against which new markers for this malignancy should be judged.

    Background:Conflicting results about the association between expression level of excision repair cross-complementation group 1 (ERCC1) and clinical outcome in patients with colorectal cancer (CRC) receiving chemotherapy have been reported.Thus,we searched the available articles and performed the meta-analysis to elucidate the prognostic role of ERCC1 expression in patients with CRC.Methods:A thorough literature search using PubMed (Medline),Embase,Cochrane Library,Web of Science databases,and Chinese Science Citation Database was conducted to obtain the relevant studies.Pooled hazard ratios (HRs) or odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to estimate the results.Results:A total of 11 studies were finally enrolled in this meta-analysis.Compared with patients with lower ERCC1 expression,patients with higher ERCC1 expression tended to have unfavorable overall survival (OS) (HR =2.325,95% CI:1.720-3.143,P < 0.001),progression-free survival (PFS) (HR =1.917,95% CI:1.366-2.691,P < 0.001) and poor response to chemotherapy (OR =0.491,95% CI:0.243-0.990,P =0.047).Subgroup analyses by treatment setting,ethnicity,HR extraction,detection methods,survival analysis,and study design demonstrated that our results were robust.Conclusions:ERCC1 expression may be taken as an effective prognostic factor predicting the response to chemotherapy,OS,and PFS.Further studies with better study design and longer follow-up are warranted in order to gain a deeper understanding of ERCC 1's prognostic value.

    Full Text Available Abstract Background Fatigue is a major problem of cancer patients. Thirty percent of cancer survivors report serious fatigue three years after finishing treatment. There is evidence that physical exercise during cancer treatment reduces fatigue. This may also lead to an improvement of quality of life. Such findings may result in a decrease of healthcare related expenditures and societal costs due to sick leave. However, no studies are known that investigated these hypotheses. Therefore, the primary aim of our study is to assess the effect of exercise during cancer treatment on reducing complaints of fatigue and on reducing health service utilisation and sick leave. Methods/Design The Physical Activity during Cancer Treatment study is a multicentre randomised controlled trial in 150 breast and 150 colon cancer patients undergoing cancer treatment. Participants will be randomised to an exercise or a control group. In addition to the usual care, the exercise group will participate in an 18-week supervised group exercise programme. The control group will be asked to maintain their habitual physical activity pattern. Study endpoints will be assessed after 18 weeks (short term and after 9 months (long term. Validated questionnaires will be used. Primary outcome: fatigue (Multidimensional Fatigue Inventory and Fatigue Quality List and cost-effectiveness, health service utilisation and sick leave. Secondary outcome: health related quality of life (European Organisation Research and Treatment of Cancer-Quality of Life questionnaire-C30, Short Form 36 healthy survey, impact on functioning and autonomy (Impact on functioning and autonomy questionnaire, anxiety and depression (Hospital Anxiety and Depression Scale, physical fitness (aerobic peak capacity, muscle strength, body composition and cognitive-behavioural aspects.
