Objective: University students face high levels of stress-related factors, such as an unfamiliar environment, challenging workload, and uncertainty about their ability to succeed. Participants: A total of 370 students in Qatar who consented to participate between February 2017 and February 2018. Methods: This cross-sectional study assessed perceived stress [using a validated 4-point perceived stress scale (PSS-4)], as well as diet, exercise, body mass index, sleep, and life satisfaction. Results: Among students aged 18-39 (mean = 20.1 ± 3.0 years), PSS-4 scores varied between 0 and 16 (mean = 7.4 ± 3.4). Elevated stress was significantly associated with female sex, country of origin, residing off-campus, eating when bored, lack of self-discipline, disturbed sleep, and low levels of life satisfaction. Furthermore, students with PSS-4 scores above the median level were 2.3 times likelier to report difficulty concentrating on academic work. Conclusion: Elevated stress levels are present in university students in Qatar. Strengthening coping skills may improve health and academic performance.

Background: Around 7% of women who undergo breast-conserving surgery (BCS) or mastectomy are at risk of developing ipsilateral breast tumor recurrence (IBTR). When assessing risks that, like that of IBTR, depend on multiple clinicopathological variables, nomograms are the predictive tools of choice. In this study, two independent nomograms were constructed to estimate the individualized risk of IBTR after breast surgery., Patients and Methods: In this retrospective study, 18,717 consecutive patients with primary invasive breast cancer were enrolled. The training set used for building the nomograms comprised 15,124 patients (11,627 treated with BCS and 3497 with mastectomy), while the validation set included 3593 women (2565 BCS and 1028 mastectomy). Median follow-up time was 8 years in the training set and 6 years in the validation set. Multivariable Cox proportional hazards regression was used to identify independent factors for IBTR. Two separated nomograms were constructed on multivariate models for BCS and mastectomy., Results: The factors that associated with IBTR after either BCS or mastectomy were identified. The two multivariable models were used to build nomograms for the prediction of IBTR 1 year, 5 years, and 10 years after BCS or after mastectomy. Five-year and 10-year IBTR rates in the BCS training set were equal to 3.50% and 7.00%, respectively, and to 5.39% and 7.94% in the mastectomy training set. The nomograms were subsequently validated with c-index values of 0.77 and 0.69 in the BCS and mastectomy validation sets, respectively., Conclusions: The nomograms presented in this study provide clinicians and patients with a valuable decision-making tool for choosing between different treatment options for invasive breast cancer.

Background: Pancreatic ductal adenocarcinoma (PDAC) is associated with poor prognosis. Gemcitabine is the standard chemotherapy for patients with metastatic pancreatic adenocarcinoma (MPA). Randomized clinical trials evaluating intensified chemotherapies including FOLFIRINOX and nab-paclitaxel plus gemcitabine (NAB+GEM) have shown improvement in survival. Here, we have evaluated the efficacy of intensified chemotherapy versus gemcitabine monotherapy in real-life settings across Europe., Methods: A retrospective multi-center study including 1056 MPA patients, between 2012 and 2015, from nine centers in UK, Germany, Italy, Hungary and the Swedish registry was performed. Follow-up was at least 12 months. Cox proportional Harzards regression was used for uni- and multivariable evaluation of prognostic factors., Results: Of 1056 MPA patients, 1030 (98.7%) were assessable for survival analysis. Gemcitabine monotherapy was the most commonly used regimen (41.3%), compared to FOLFIRINOX (n = 204, 19.3%), NAB+GEM (n = 81, 7.7%) and other gemcitabine- or 5-FU-based regimens (n = 335, 31.7%). The median overall survival (OS) was: FOLFIRINOX 9.9 months (95%CI 8.4-12.6), NAB+GEM 7.9 months (95%CI 6.2-10.0), other combinations 8.5 months (95%CI 7.7-9.3) and gemcitabine monotherapy 4.9 months (95%CI 4.4-5.6). Compared to gemcitabine monotherapy, any combination of chemotherapeutics improved the survival with no significant difference between the intensified regimens. Multivariable analysis showed an association between treatment center, male gender, inoperability at diagnosis and performance status (ECOG 1-3) with poor prognosis., Conclusion: Gemcitabine monotherapy was predominantly used in 2012-2015. Intensified chemotherapy improved OS in comparison to gemcitabine monotherapy. In real-life settings, the OS rates of different treatment approaches are lower than shown in randomized phase III trials., (Copyright © 2018 IAP and EPC. All rights reserved.)

Background: Acute pancreatitis (AP) is the most common complication after endoscopic retrograde cholangiopancreatography (ERCP). Statins have been traditionally associated to an increased risk of AP, however, recent evidence suggests that statins may have a protective role against this disease., Aims: Our primary aim is to investigate whether the use of statins has a protective effect against post-ERCP pancreatitis (PEP). Secondary outcomes are: to evaluate the effect of other drugs on the incidence of PEP; to ascertain the relationship between the use of statins and the severity of PEP; and to evaluate the effect of other risk and protective factors on the incidence of PEP., Methods: STARK is an international multicenter prospective cohort study. Centers from Spain, Italy, Croatia, Finland and Sweden joined this study. The total sample size will include about 1016 patients, which was based on assuming a 5% incidence of PEP among non-statin (NSt) users, a 1-3 ratio of statin (St) and NSt consumers respectively, a 70% decrease in PEP among St consumers, an alpha-error of 0.05 and beta-error of 0.20. All patients aged ≥18 years scheduled for ERCP will be offered to enter the study., Discussion: STARK study will ascertain whether statins, a safe, widely used and inexpensive drug, can modify the incidence of PEP., (Copyright © 2018 Editrice Gastroenterologica Italiana S.r.l.

Background & Aims: The association between pancreatic intraductal papillary mucinous neoplasms (IPMNs) and extrapancreatic neoplasms (EPNs) is controversial. We performed a multicenter observational study to assess the incidence of EPNs after an IPMN diagnosis., Methods: 1340 patients with IPMNs were evaluated from 2000 through 2013 at 4 academic institutions in Europe for development of EPN. To estimate the actual incidence of EPN, we excluded patients with an EPN previous or synchronous to the IPMN, and patients who had been followed for less than 12 months, resulting in a study population of 816 patients. The incidence of EPN was compared with sex-specific, age-adjusted European cancer statistics; the standardized incidence ratio (SIR), and the 5- and 10-year cumulative incidence rates were calculated., Results: A total of 290/1340 patients had a history of EPN (prevalence of 21.6%). In this subgroup of patients, the IPMN was discovered incidentally in 241. Among the 816 patients included in the incidence analysis, 50 developed an EPN after a median time of 46 months from study enrollment. The incidence of any EPN was not greater in patients with than without IPMN with a SIR of 1.48 (95% confidence interval, 0.94-2.22) in males and of 1.39 (95% CI 0.90-2.05) in females. The 5- and 10-year cumulative incidence rates for development of EPN in patients with IPMN were 7.9% and 16.6% in men, and 3.4% and 23.1% in women., Conclusions: Patients with IPMN do not have a significantly higher incidence of EPNs than the general European population. It might not be necessary to screen patients with IPMN for EPN., (Copyright © 2015 AGA Institute. Published by Elsevier Inc. All rights reserved.)

Purpose: To verify how the classification according to the American Society for Therapeutic Radiation Oncology (ASTRO) consensus statement (CS) for the application of accelerated partial breast irradiation (APBI) fits patients treated with intraoperative radiotherapy with electrons (ELIOT) at a single institution., Methods and Materials: The study included 1,822 patients treated with ELIOT as the sole radiation modality outside of a clinical trial at the European Institute of Oncology after breast-conserving surgery for invasive breast cancer, who were classified into CS groups of suitable, cautionary, and unsuitable. The outcome in terms of ipsilateral breast recurrence, regional node relapse, distant metastases, progression free-survival, cause-specific survival, and overall survival were assessed., Results: All the 1,822 cases except for 25 could be classified according to ASTRO CS: 294 patients met the criteria for inclusion into the suitable group, 691 patients into the cautionary group, and 812 patients into the unsuitable group. The 5-year rate of ipsilateral breast recurrence for suitable, cautionary, and unsuitable groups were 1.5%, 4.4%, and 8.8%, respectively (p = 0.0003). Whereas the regional node relapse showed no difference, the rate of distant metastases was significantly different in the unsuitable group compared with the suitable and cautionary groups, having a significant impact on survival., Conclusion: In the context of patients treated with ELIOT, the ASTRO guidelines identify well the groups for whom APBI might be considered as an effective alternative to whole breast radiotherapy and also identify groups for whom APBI is not indicated., (Copyright © 2012 Elsevier Inc.

Aim of the Study: We performed a meta-analysis to assess whether MC1R variants increase the risk of melanoma in CDKN2A mutation carriers of melanoma-prone families., Methods: Data from 96 CDKN2A-positive melanoma-prone families from seven independent populations of Europe, United States and Australia were included in the analysis. Summary risk estimates were calculated by random-effect models. We explored between-study heterogeneity and publication bias. Association between MC1R variants and age at diagnosis was assessed by the non-parametric Wilcoxon test., Results: CDKN2A mutation carriers with 1 MC1R variant showed a double melanoma risk as compared to CDKN2A mutation carriers without MC1R variants (Summary OR; 95%CI: 2.2; 1.1-4.5). MC1R heterozygous subjects had no significantly higher melanoma risk than wild-type subjects (1.6; 0.5-5.4) while carriers of multiple MC1R variants had a more than four-times higher melanoma risk (4.6; 1.3-16.4). Carriers of red hair colour (RHC) variants showed an increased melanoma risk with a Summary OR of 3.5 (95%CI: 1.3-9.9). CDKN2A mutation carriers with MC1R variants had a statistically significant lower median age at melanoma diagnosis than CDKN2A mutation carriers with no MC1R variants (37years versus 47years, p-value<0.0001)., Conclusion: MC1R variants significantly increase penetrance of CDKN2A mutations in melanoma-prone families, especially with respect to multiple MC1R variants and to RHC variants. A significant anticipation of melanoma diagnosis is observed in CDKN2A mutation carriers with MC1R variants., (Copyright (c) 2010 Elsevier Ltd. All rights reserved.)

Background: Against a background of increasing cancer rates in the mid-1980s, Europe Against Cancer launched an ambitious programme aiming to reduce cancer mortality by 15% by the year 2000. A programme of activities and research, focussing on three major themes [prevention (particularly tobacco control), screening, and education and training], was developed together with the European Code Against Cancer., Methods: To evaluate the outcome of the programme, all cancer mortality data were abstracted for each member state of the European Union (EU) until the most recent year available. For each gender group in each member state, age-specific rates were estimated for 2000. For each country-gender grouping, the standardized mortality rate (SMR) and expected numbers of deaths in 2000 were calculated based on the age-specific rates for 1985 and the population estimates for 2000. The ratio of the SMR in 2000 to that of 1985, was used as the measure to compare mortality rates., Results: In 1985, there were 850 194 cancer deaths in the EU. Based solely on demographic considerations, this number was expected to rise to 1 033 083 in the year 2000. Between 1985 and 2000, the number of cancer deaths increased in both men (+12%) and women (+9%). The target of a 15% reduction in the expected numbers of cancer deaths in the EU was not met, although the 10% reduction in number of deaths expected in men and 8% in women, along with a 11% reduction in risk of cancer death in men and a 10% reduction in women, was noteworthy. Only Austria and Finland achieved the 15% reductions in deaths in both men and women. The UK and Luxembourg (where the small population and annual number of deaths make interpretation difficult) came close to meeting these targets, as did Italy. Portugal and Greece had the poorest performance, with increases in each gender group., Conclusions: Cancer deaths in the EU were expected to rise from 850 194 in 1985 to 1 033 083 in 2000. It is estimated that there will be 940 510 cancer deaths that year, due to the decline in risk observed since 1985. The Europe Against Cancer programme appears to have been associated with the avoidance of 92 573 cancer deaths in the year 2000. With few exceptions, most countries are experiencing declining trends in cancer death rates, which seem set to continue, at least in the near future. Renewed tobacco control efforts are clearly needed for women, and there is a strong case for the introduction of organized breast and cervix screening programmes in all member states. Continuing to emphasize prevention within cancer control will help to promote the continuing decline in death rates in the future.

Patients on maintenance dialysis have increased risk for cancer, especially in the kidney and urinary tract. In a retrospective cohort of 831,804 patients starting dialysis during 1980 to 1994 in the United States, Europe, or Australia and New Zealand, standardized incidence ratios (SIR) with 95% confidence intervals (CI) were calculated for kidney and bladder cancers. Risks for cancers of the kidney (SIR 3.6; CI 3.5 to 3.8) and bladder (SIR 1.5; CI 1.4 to 1.6) were increased, relatively more in younger than older patients and more in female patients (kidney: SIR 4.6, CI 4.3 to 4.9; bladder: SIR 2.7, CI 2.4 to 2.9) than male patients (kidney: SIR 3.2, CI 3.0 to 3.4; bladder: SIR 1.3, CI 1.2 to 1.3). SIR for kidney cancer were raised in all categories of primary renal disease, and for bladder cancer in all but diabetes and familial, hereditary diseases. Notably high SIR occurred in toxic nephropathies (chiefly analgesic nephropathy) and miscellaneous conditions (a category that includes Balkan nephropathy), the excess of kidney cancer in these conditions being urothelial in origin. SIR for kidney cancer rose significantly, and those for bladder cancer fell (not reaching significance) with time on dialysis. There was no association with type of dialysis. The pattern of increased risk for renal parenchymal cancer in dialysis patients is consistent with causation through acquired renal cystic disease and of urothelial cancers of the kidney and bladder with the carcinogenic effects of certain primary renal diseases.

This report notes the differences in the classification of the primary renal disease (PRD) used in different renal dialysis and transplant registries worldwide. The heterogeneity of coding systems complicates the comparative analysis of end-stage renal disease from different regions. Using data collected over two decades in the United States, Europe, and Australia/New Zealand, we present a method for reorganization of the classes of PRD that allows a straightforward comparison of retrospective data from these registries.

Background: Previous studies have suggested that the frequency of cancer is higher in patients with end-stage renal disease (ESRD) than in the general population, but have not established whether this increase is confined to certain cancers or to certain categories of ESRD patients. The aim of this study was to examine the risk of cancer in a large cohort of patients treated by dialysis but not transplantation., Methods: We assembled a cohort of 831,804 patients who received dialysis during the period 1980-94 for ESRD in the USA, Europe, Australia, or New Zealand. We compared the observed frequency of cancer among these patients during 2,045,035 person-years of follow-up with the frequency of cancer in the respective background populations., Findings: During average follow-up of 2.5 years, 25,044 (3%) of 831,804 patients developed cancer compared with an expected number of 21,185 (standardised incidence ratio 1.18 [95% CI 1.17-1.20]). We observed a higher risk of cancer in patients younger than 35 years (3.68 [3.39-3.99]), and the risk gradually decreased with increasing age. High risks were observed for cancer of the kidney (3.60 [3.45-3.76]), bladder (1.50 [1.42-1.57]), and thyroid and other endocrine organs (2.28 [2.03-2.54]). Excess cancers appeared in several organs for which viruses have been suspected as causative agents, whereas cancers of the lung, colorectum, prostate, breast, and stomach were not consistently increased., Interpretation: The overall risk of cancer is increased in patients with ESRD, and the distribution of tumour types resembles the pattern seen after transplantation (although we have no data to make the comparison with skin cancer). The excess risk can largely be ascribed to effects of underlying renal or urinary-tract disease, or of loss of renal function, on the kidney and bladder, and to increased susceptibility to viral carcinogenesis. The relative risk, which is especially high in younger patients, gradually diminishes with age.

Background: Anecdotal reports suggest an increased frequency of certain cancers in patients with cystic fibrosis, the commonest genetic disorder of whites. One third of patients with cystic fibrosis now reach adulthood, when cancer is more frequent, implying that cancer rates in these patients will increase over time. We investigated the relation between cystic fibrosis and cancer in North American and European patients with cystic fibrosis. Methods. We performed a retrospective cohort study of the occurrence of cancer in 28,511 patients with cystic fibrosis from 1985 through 1992 in the United States and Canada. The number of cases observed was compared with the number expected, calculated from population-based data on the incidence of cancer. We also analyzed proportional incidence ratios to assess the association between specific cancers and cystic fibrosis in Europe., Results: Thirty-seven cancers were observed in the North American cohort during 164,764 person-years of follow-up, as compared with an expected number of 45.6, yielding a ratio of observed to expected cancers of 0.8 (95 percent confidence interval, 0.6 to 1.1). Thirteen digestive tract tumors were observed, as compared with an expected number of two, for a ratio of observed to expected cancers of 6.5 (95 percent confidence interval, 3.5 to 11.1). In Europe, 11 of 39 cancers originated in the digestive tract, yielding a positive association between digestive tract tumors and cystic fibrosis (odds ratio, 6.4; 95 percent confidence interval, 2.9 to 14.0)., Conclusions: Although the overall risk of cancer in patients with cystic fibrosis is similar to that of the general population, there is an increased risk of digestive tract cancers. Persistent or unexplained gastrointestinal symptoms in these patients should be carefully investigated.

Background: The results of case-control studies and anecdotal reports suggest that pancreatitis may be a risk factor for pancreatic cancer, but there have been no studies of sufficient size and power to assess the magnitude of the relation between these two diseases., Methods and Results: We undertook a multicenter historical cohort study of 2015 subjects with chronic pancreatitis who were recruited from clinical centers in six countries. A total of 56 cancers were identified among these patients during a mean (+/-SD) follow-up of 7.4 +/- 6.2 years. The expected number of cases of cancer calculated from country-specific incidence data and adjusted for age and sex was 2.13, yielding a standardized incidence ratio (the ratio of observed to expected cases) of 26.3 (95 percent confidence interval, 19.9 to 34.2). For subjects with a minimum of two or five years of follow-up, the respective standardized incidence ratios were 16.5 (95 percent confidence interval, 11.1 to 23.7) and 14.4 (95 percent confidence interval, 8.5 to 22.8). The cumulative risk of pancreatic cancer in subjects who were followed for at least 2 years increased steadily, and 10 and 20 years after the diagnosis of pancreatitis, it was 1.8 percent (95 percent confidence interval, 1.0 to 2.6 percent) and 4.0 percent (95 percent confidence interval, 2.0 to 5.9 percent), respectively., Conclusions: The risk of pancreatic cancer is significantly elevated in subjects with chronic pancreatitis and appears to be independent of sex, country, and type of pancreatitis.

A summary of smoking and cancer in various European countries is presented Important points are the tobacco/alcohol interaction in the elevated mortality rates from upper digestive and respiratory tract neoplasms in France and other southern European countries, the delay in the lung cancer epidemic in females compared with the situation in North America (with the major exception of the United Kingdom) and the different pattern of lung cancer rates in younger compared with older generations (which suggests that eastern and southern European countries will have the highest lung cancer rates at the beginning of the next century in the absence of urgent intervention). The efficacy of anti-smoking policies in Scandinavian countries which now have the lowest lung cancer rates in Europe and the persisting importance of high-tar dark-tobacco cigarettes in eastern and southern Europe in enhancing the risk not only of cancer of the lung but also of upper digestive and respiratory and bladder neoplasms are also discussed.

Age-specific mortality rates from esophageal cancer in men are considered by year of birth in European countries with different levels of alcohol consumption. In countries with high and increasing levels of alcohol consumption (Denmark, Hungary, Federal Republic of Germany, and Czechoslovakia) successive birth cohorts born after about 1910 experience increasing mortality from esophageal cancer in all age-groups. No clear trend in esophageal cancer mortality was observed in countries starting from lower levels of alcohol consumption, even in the presence of increasing consumption (Sweden, Norway, Finland, Netherlands, Poland, UK). There was an apparent threshold around 8 l of ethanol per capita per year. Likewise, no upward trend in esophageal cancer mortality was observed in countries with high and stable alcohol consumption (France, Italy, Portugal). These findings are in agreement with results of analytic epidemiologic studies which indicate that esophageal cancer mortality is only slightly affected by moderate doses of alcohol, but rises steeply with consumption of large quantities. The incidence and mortality of esophageal cancer is likely to increase further in the future in countries where the level of alcohol consumption was relatively high in 1960 and where consumption increased further in the 1960s and 1970s.
