- Purpose:To assess adolescent and young adult siblings' perception of social support prior to and following the loss of their brother or sister to cancer, 2 to 9 years earlier, and their anxiety at follow-up. Method: In 2009, 174 (73%) bereaved siblings (12-25 years) participated in a nationwide, long-term follow-up study in Sweden using an anonymous study-specific questionnaire. The Hospital Anxiety and Depression Scale was used to measure self-assessed anxiety. Results: Siblings had a higher risk of anxiety if they perceived their need for social support was unsatisfied during their brother or sisters' last month before death, relative risk (RR) = 3.6 (95% confidence interval [CI] = 1.8-7.3); time after death, RR = 2.9 (95% CI = 1.5-5.6); and at follow-up, RR = 3.8 (95% CI = 2.0-7.2). Furthermore, a higher risk for anxiety was shown for siblings if they did not perceive that their parents and neighbors cared for them after their brother or sisters' death, RR = 2.7 (95% CI = 1.3-5.5), RR = 5.4 (95% CI = 1.3-21.9), respectively. Conclusion: Bereaved siblings had a greater probability to report self-assessed anxiety if they perceived that their need for social support was not satisfied prior to and following death. Information from both nurses and other health care professionals to families about the impact of social support may contribute to lessen the siblings' risk of anxiety.

- Background: Previous studies include too few patients over 70 years to be able to assess treatment effects on Health Related Quality Of Life (HRQOL) in the older age group. We aimed to follow HRQOL in postmenopausal women (55-80 years) with breast cancer receiving adjuvant treatment, until five years post-treatment, and compare with a general population.Patients and methods: The patient sample included 150 women (adjuvant CT n=75 and RT n=75) and two reference samples from the Swedish SF-36 norm database.Results: Data from baseline showed significantly higher levels of physical functioning and general health among the patients compared to the reference sample, and significantly lower levels of bodily pain, emotional role functioning and mental health. Longitudinal analyses showed significant changes in all scales, and three different patterns (a decrease-stable, a decrease-increase, and a stable- increase pattern) were identified.Conclusion: Postmenopausal women seem to successfully manage the effects of adjuvant treatment on HRQOL.

- Vitamin C is known to protect mucosal tissues from oxidative stress and inhibit nitrosamine formation in the stomach. High consumption of fruits, particularly citrus, and higher circulating vitamin C concentrations may be inversely associated with gastric cancer (GC) risk. We investigated 20 polymorphisms in vitamin C transporter genes SCL23A1 and SCL23A2 and GC risk in 365 cases and 1,284 controls nested within the European Prospective Investigation into Cancer and Nutrition cohort. We also evaluated the association between these polymorphisms and baseline plasma vitamin C levels in a subset of participants. Four SNPs were predictors of plasma vitamin C levels (SLC23A1 rs11950646 and rs33972313; SLC23A2 rs6053005 and rs6133175) in multivariable linear regression models. One SNP (SLC23A2 rs6116569) was associated with GC risk, in particular non-cardia GC (OR = 1.63, 95 % CI = 1.11-2.39, based on 178 non-cardia cases), but this association was attenuated when plasma vitamin C was included in the logistic regression model. Haplotype analysis of SLC23A1 yielded no associations with GC. In SLC23A2, one haplotype was associated with both overall and non-cardia GC, another haplotype was associated with GC overall, and a third was associated with intestinal-type GC. Common variants in SLC23A1 and SLC23A2 may influence plasma vitamin C concentration independent of dietary intake, and variation in SLC23A2 may influence GC risk. Additional prospective studies in large populations and consortia are recommended. Investigation of variation in vitamin C transporter genes may shed light on the preventative properties of vitamin C in gastric carcinogenesis.

- ObjectiveThe objective of the present study is to examine bereaved siblings' perception of research participation.MethodsA Swedish nationwide study on avoidable and modifiable health care‐related factors in paediatric oncology among bereaved siblings who lost a brother or sister to cancer between the years 2000 and 2007 was conducted. Data are presented as proportions, and the differences between groups were statistically tested at the 5% significant level using Fisher's exact test.ResultsOut of 240 eligible siblings, 174 responded (73 %). None of the siblings (0/168) thought their participation would affect them negatively in the long term. However, 13% (21/168) stated it was a negative experience to fill out the questionnaire, whereas 84% (142/169) found it to be a positive experience. Women were more likely to report their participation as positive in a long‐term perspective compared with men (p = 0.018).ConclusionsNone of the bereaved siblings in this Swedish nationwide study anticipated any long‐term negative effect from their research participation. A majority reported it as positive to revisit their needs and experiences throughout their brother or sister's illness and death 2–9 years following the loss. We believe that the stepwise approach used in this study contributed to the high acceptance.

- Objective To investigate whether work related stress, measured and defined as job strain, is associated with the overall risk of cancer and the risk of colorectal, lung, breast, or prostate cancers.Design Meta-analysis of pooled prospective individual participant data from 12 European cohort studies including 116 056 men and women aged 17-70 who were free from cancer at study baseline and were followed-up for a median of 12 years. Work stress was measured and defined as job strain, which was self reported at baseline. Incident cancers (all n=5765, colorectal cancer n=522, lung cancer n=374, breast cancer n=1010, prostate cancer n=865) were ascertained from cancer, hospital admission, and death registers. Data were analysed in each study with Cox regression and the study specific estimates pooled in meta-analyses. Models were adjusted for age, sex, socioeconomic position, body mass index (BMI), smoking, and alcohol intakeResults A harmonised measure of work stress, high job strain, was not associated with overall risk of cancer (hazard ratio 0.97, 95% confidence interval 0.90 to 1.04) in the multivariable adjusted analyses. Similarly, no association was observed between job strain and the risk of colorectal (1.16, 0.90 to 1.48), lung (1.17, 0.88 to 1.54), breast (0.97, 0.82 to 1.14), or prostate (0.86, 0.68 to 1.09) cancers. There was no clear evidence for an association between the categories of job strain and the risk of cancer.Conclusions These findings suggest that work related stress, measured and defined as job strain, at baseline is unlikely to be an important risk factor for colorectal, lung, breast, or prostate cancers.

- BackgroundPatients with well-differentiated small intestine neuroendocrine tumors (WD-SI-NET) are most often diagnosed at a metastatic stage of disease, which reduces possibilities for a curative treatment. Thus new approaches for earlier detection and improved monitoring of the disease are required.Materials and methodsSuspension bead arrays targeting 124 unique proteins with antibodies from the Human Protein Atlas were used to profile biotinylated serum samples. Discoveries from a cohort of 77 individuals were followed up in a cohort of 132 individuals both including healthy controls as well as patients with untreated primary WD-SI-NETs, lymph node metastases and liver metastases.Results A set of 20 antibodies suggested promising proteins for further verification based on technically verified statistical significance. Proceeding, we assessed the classification performance in an independent cohort of patient serum, achieving, classification accuracy of up to 85% with different subsets of antibodies in respective pairwise group comparisons. The protein profiles of nine targets, namely IGFBP2, IGF1, SHKBP1, ETS1, IL1α, STX2, MAML3, EGR3 and XIAP were verified as significant contributors to tumor classification.ConclusionsWe propose new potential protein biomarker candidates for classifying WD-SI-NET at different stage of disease. Further evaluation of these proteins in larger sample sets and with alternative approaches is needed in order to further improve our understanding of their functional relation to WD-SI-NET and their eventual use in diagnostics.

- Menstrual and reproductive factors and exogenous hormone use have been investigated as pancreatic cancer risk factors in case-control and cohort studies, but results have been inconsistent. We conducted a prospective examination of menstrual and reproductive factors, exogenous hormone use and pancreatic cancer risk (based on 304 cases) in 328,610 women from the EPIC cohort. Then, in a case-control study nested within the EPIC cohort, we examined 12 single nucleotide polymorphisms (SNPs) in CYP17A1 (an essential gene in sex steroid metabolism) for association with pancreatic cancer in women and men (324 cases and 353 controls). Of all factors analyzed, only younger age at menarche (<12 vs. 13 years) was moderately associated with an increased risk of pancreatic cancer in the full cohort; however, this result was marginally significant (HR = 1.44; 95% CI = 0.99-2.10). CYP17A1 rs619824 was associated with HRT use (p value = 0.037) in control women; however, none of the SNPs alone, in combination, or as haplotypes were associated with pancreatic cancer risk. In conclusion, with the possible exception of an early age of menarche, none of the menstrual and reproductive factors, and none of the 12 common genetic variants we evaluated at the CYP17A1 locus makes a substantial contribution to pancreatic cancer susceptibility in the EPIC cohort. What's new Because the incidence of pancreatic cancer is 30-50% higher in men than women, researchers have wondered whether exposure to estrogen might offer a protective effect. The answer thus far has been unclear, however. In this study, the authors examined menstrual and reproductive factors in women, as well as exogenous hormone use. They also examined variants of the CYP17A1 gene in both women and men, as this gene is essential for sex-steroid metabolism. Only early age of menarche showed any association with pancreatic cancer risk. Copyright © 2012 UICC.

- AIM: The aim of this study was to describe surgical nurses' perceived work-related stress in the care of severely ill and dying patients with cancer after participating in an educational intervention on existential issues. METHODS AND SAMPLE: This article reports a mixed methods pilot study of an education programme consisting of lectures and supervised discussions conducted in 2009-2010 in three surgical wards in a county hospital in Sweden. The concurrent data collections consisted of repeated interviews with eleven nurses in an educational group, and questionnaires were distributed to 42 nurses on four occasions. RESULTS: Directly after the educational intervention, the nurses described working under high time pressure. They also described being hindered in caring because of discrepancies between their caring intentions and what was possible in the surgical care context. Six months later, the nurses described a change in decision making, and a shift in the caring to make it more in line with their own intentions and patients' needs rather than the organizational structure. They also reported decreased feelings of work-related stress, decreased stress associated with work-load and feeling less disappointed at work. CONCLUSIONS: Results indicate that it may be possible to influence nurses' work-related stress through an educational intervention. According to nurses' descriptions, reflecting on their ways of caring for severely ill and dying patients, many of whom had cancer, from an existential perspective, had contributed to enhanced independent decision making in caring. This in turn appears to have decreased their feelings of work-related stress and disappointment at work.

Impact of Prior Traumatic Life Events on Parental Early Stage Reactions following a Child's Cancer
- 2013
-
Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 8:3
-
Tidskriftsartikel (refereegranskat)abstract
- Background: In pediatric oncology, effective clinic-based management of acute and long-term distress in families calls for investigation of determinants of parents' psychological response to the child's cancer. We examined the relationship between parents' prior exposure to traumatic life events (TLE) and the occurrence of posttraumatic stress symptoms (PTSS) following their child's cancer diagnosis. Factors mediating the TLE-PTSS relationship were analyzed. Methodology: The study comprised 169 parents (97 mothers, 72 fathers) of 103 cancer diagnosed children (median age: 5,9 years; range 0.1-19.7 years). Thirty five parents were of immigrant origin (20.7%). Prior TLE were collated using a standardized questionnaire, PTSS was assessed using the Impact of Events-Revised (IES-R) questionnaire covering intrusion, avoidance and hyperarousal symptoms. The predictive significance of prior TLE on PTSS was tested in adjusted regression models. Results: Mothers demonstrated more severe PTSS across all symptom dimensions. TLE were associated with significantly increased hyperarousal symptoms. Parents' gender, age and immigrant status did not significantly influence the TLE-PTSS relationship. Conclusions: Prior traumatic life-events aggravate posttraumatic hyperarousal symptoms. In clinic-based psychological care of parents of high-risk pediatric patients, attention needs to be paid to life history, and to heightened vulnerability to PTSS associated with female gender.

- Prostate cancer and its outcomes are a real threat for health and well-being for men living in the Western world. The number of men with a diagnosis of prostate cancer, before the age of 65 years, has increased in recent decades. The aim of this study was to explore how some of these Swedish men experienced and talked about their sexuality. Four focus group discussions were performed in the context of associations for prostate cancer. Using qualitative content analysis, it was identified how the diagnosis was a threat to their male identity; the men's vulnerability as a group in society was made explicit. Their sexuality was diminished by their illness experiences. These experiences were difficult to share and talk about with others and therefore connected with silence and sorrow. As a result of this, the informants often played a passive role when or if they discussed issues related to sexuality with someone in the health care organizations. The possibility of voluntarily joining a cancer association was probably highly beneficial for these men. During the sessions, several men expressed the opinion that "it is always great to talk."
