- Introduction: Previous analysis from the large European multicentre ESCAPE study showed an association of ambient particulate matter < 2.5 mu m (PM2.5) air pollution exposure at residence with the incidence of gastric cancer. It is unclear which components of PM are most relevant for gastric and also upper aerodigestive tract (UADT) cancer and some of them may not be strongly correlated with PM mass. We evaluated the association between long-term exposure to elemental components of PM2.5 and PM10 and gastric and UADT cancer incidence in European adults.Methods: Baseline addresses of individuals were geocoded and exposure was assessed by land-use regression models for copper (Cu), iron (Fe) and zinc (Zn) representing non-tailpipe traffic emissions; sulphur (S) indicating long-range transport; nickel (Ni) and vanadium (V) for mixed oil-burning and industry; silicon (Si) for crustal material and potassium (K) for biomass burning. Cox regression models with adjustment for potential confounders were used for cohort-specific analyses. Combined estimates were determined with random effects meta-analyses.Results: Ten cohorts in six countries contributed data on 227,044 individuals with an average follow-up of 14.9 years with 633 incident cases of gastric cancer and 763 of UADT cancer. The combined hazard ratio (HR) for an increase of 200 ng/m(3) of PM2.5_S was 1.92 (95%-confidence interval (95%-CI) 1.13; 3.27) for gastric cancer, with no indication of heterogeneity between cohorts (I-2= 0%), and 1.63 (95%-CI 0.88; 3.01) for PM2.5_Zn (I-2= 70%). For the other elements in PM2.5 and all elements in PM10 including PM10_S, non-significant HRs between 0.78 and 1.21 with mostly wide CIs were seen. No association was found between any of the elements and UADT cancer. The HR for PM2.5_S and gastric cancer was robust to adjustment for additional factors, including diet, and restriction to study participants with stable addresses over follow-up resulted in slightly higher effect estimates with a decrease in precision. In a two-pollutant model, the effect estimate for total PM2.5 decreased whereas that for PM2.5_S was robust.Conclusion: This large multicentre cohort study shows a robust association between gastric cancer and long-term exposure to PM2.5 S but not PM10 S, suggesting that S in PM2.5 or correlated air pollutants may contribute to the risk of gastric cancer.

- 2016
-
In: British Journal of Cancer. - : Springer Science and Business Media LLC. - 0007-0920 .- 1532-1827. ; 114, s. 813-818

Journal article (peer-reviewed)abstract
- BACKGROUND: Working longer than the maximum recommended hours is associated with an increased risk of cardiovascular disease, but the relationship of excess working hours with incident cancer is unclear.METHODS: This multi-cohort study examined the association between working hours and cancer risk in 116 462 men and women who were free of cancer at baseline. Incident cancers were ascertained from national cancer, hospitalisation and death registers; weekly working hours were self-reported.RESULTS: During median follow-up of 10.8 years, 4371 participants developed cancer (n colorectal cancer: 393; n lung cancer: 247; n breast cancer: 833; and n prostate cancer: 534). We found no clear evidence for an association between working hours and the overall cancer risk. Working hours were also unrelated the risk of incident colorectal, lung or prostate cancers. Working ⩾55 h per week was associated with 1.60-fold (95% confidence interval 1.12-2.29) increase in female breast cancer risk independently of age, socioeconomic position, shift- and night-time work and lifestyle factors, but this observation may have been influenced by residual confounding from parity.CONCLUSIONS: Our findings suggest that working long hours is unrelated to the overall cancer risk or the risk of lung, colorectal or prostate cancers. The observed association with breast cancer would warrant further research.

Multidisciplinary European Low Dose Initiative (MELODI) : strategic research agenda for low dose radiation risk research
- 2018
-
In: Radiation and Environmental Biophysics. - : Springer Science and Business Media LLC. - 0301-634X .- 1432-2099. ; 57:1, s. 5-15

Research review (peer-reviewed)abstract
- MELODI (Multidisciplinary European Low Dose Initiative) is a European radiation protection research platform with focus on research on health risks after exposure to low-dose ionising radiation. It was founded in 2010 and currently includes 44 members from 18 countries. A major activity of MELODI is the continuous development of a long-term European Strategic Research Agenda (SRA) on low-dose risk for radiation protection. The SRA is intended to identify priorities for national and European radiation protection research programs as a basis for the preparation of competitive calls at the European level. Among those key priorities is the improvement of health risk estimates for exposures close to the dose limits for workers and to reference levels for the population in emergency situations. Another activity of MELODI is to ensure the availability of European key infrastructures for research activities, and the long-term maintenance of competences in radiation research via an integrated European approach for training and education. The MELODI SRA identifies three key research topics in low dose or low dose-rate radiation risk research: (1) dose and dose rate dependence of cancer risk, (2) radiation-induced non-cancer effects and (3) individual radiation sensitivity. The research required to improve the evidence base for each of the three key topics relates to three research lines: (1) research to improve understanding of the mechanisms contributing to radiogenic diseases, (2) epidemiological research to improve health risk evaluation of radiation exposure and (3) research to address the effects and risks associated with internal exposures, differing radiation qualities and inhomogeneous exposures. The full SRA and associated documents can be downloaded from the MELODI website (http://www.melodi-online.eu/sra.html).

Journal article (peer-reviewed)abstract
- ObjectiveThe aim of the study was to investigate the feasibility and preliminary efficacy of an Internet‐based guided self‐help intervention for posttraumatic stress symptoms (PTSS) and related symptoms in parents of children on cancer treatment.MethodsParents of children on cancer treatment, who fulfilled the modified symptom criteria on the PTSD Checklist, were randomly allocated to the intervention or to a wait‐list control condition. The intervention group accessed a 10‐week guided self‐help program via the Internet based on principles from cognitve behavior therapy. The primary outcome PTSS and the secondary outcomes depression and anxiety were assessed by self‐report preintervention and postintervention.ResultsSeven hundred forty‐seven parents were approached and informed about the study, 92 were assessed for eligibility, and 58 were included and randomized to the intervention (n = 31) or wait list (n = 27). Eightteen participants completed the intervention. Intention‐to‐treat analyses indicated a significant effect of the intervention on PTSS with a large between‐group effect size at postassessment (Cohen's d = 0.88). The intervention group reported reductions in PTSS with a large within‐group effect size (d = 1.62) compared with a minimal reduction in the wait‐list group (d = 0.09). There was a significant intervention effect on depression and anxiety and reductions in the intervention group with large within‐group effect sizes (d = 0.85–1.09).ConclusionsFindings indicate a low enrollment rate and considerable attrition but also that Internet‐based guided self‐help shows promise for parents of children on cancer treatment who report a high level of PTSS and would like to take part in an Internet‐based intervention.

Unique proteomic signature for radiation sensitive patients; a comparative study between normo-sensitive and radiation sensitive breast cancer patients
- 2015
-
In: Mutation research. - : Elsevier BV. - 0027-5107 .- 1873-135X. ; 776, s. 128-135

Journal article (peer-reviewed)abstract
- Radiation therapy is a cornerstone of modern cancer treatment. Understanding the mechanisms behind normal tissue sensitivity is essential in order to minimize adverse side effects and yet to prevent local cancer reoccurrence. The aim of this study was to identify biomarkers of radiation sensitivity to enable personalized cancer treatment. To investigate the mechanisms behind radiation sensitivity a pilot study was made where eight radiation-sensitive and nine normo-sensitive patients were selected from a cohort of 2914 breast cancer patients, based on acute tissue reactions after radiation therapy. Whole blood was sampled and irradiated in vitro with 0, 1, or 150 mGy followed by 3 h incubation at 37 degrees C. The leukocytes of the two groups were isolated, pooled and protein expression profiles were investigated using isotope-coded protein labeling method (ICPL). First, leukocytes from the in vitro irradiated whole blood from normo-sensitive and extremely sensitive patients were compared to the non-irradiated controls. To validate this first study a second ICPL analysis comparing only the non-irradiated samples was conducted. Both approaches showed unique proteomic signatures separating the two groups at the basal level and after doses of 1 and 150 mGy. Pathway analyses of both proteomic approaches suggest that oxidative stress response, coagulation properties and acute phase response are hallmarks of radiation sensitivity supporting our previous study on oxidative stress response. This investigation provides unique characteristics of radiation sensitivity essential for individualized radiation therapy.

Sickness absence following breast cancer surgery : a two-year follow-up cohort study
- 2018

In: Scandinavian Journal of Caring Sciences. - : Wiley. - 0283-9318 .- 1471-6712. ; 32:2, s. 715-724

Journal article (peer-reviewed)abstract
- Rationale and aimMost women of working ages with limited breast cancer (BC) have returned to work within the first year after diagnosis. However, little is known about what is happening during this year regarding sickness absence and return to work. Also, the knowledge is very limited about the occurrence of part‐time sickness absence after BC diagnosis. Therefore, the aim of this study was to describe occurrence, extent and length of SA during a two‐year follow‐up after BC surgery and to analyse the association between being SA and type of cancer treatment.MethodsIn this prospective cohort study, 497 women responded to questionnaires about different aspects of sickness absence at six occasions during two years after primary BC surgery (at baseline and after 4, 8, 12, 18 and 24 months). Treatment information was obtained from the National breast cancer register. Multinomial logistic regression was used to calculate odds ratios (OR) for likelihood of being sickness absent more than once.ResultsTwo‐thirds of the women were sickness absent at baseline; this proportion decreased, especially during the first eight months. At 24 months, 13% were sickness absent. Of all women, 27% never reported sickness absence and 14% were sickness absent at most of the six survey times. At eight months, many had shifted from full‐ to part‐time sickness absence. Women with chemotherapy and/or advanced BC surgery had higher ORs for being sickness absent at most of the follow‐ups.ConclusionsMost women returned to work within the first eight months after BC surgery and of those sickness absent after that, most had been part‐time sickness absent. Thus, it is important to differentiate between part‐ and full‐time sickness absence in future studies. Special attention should be paid to the impact of chemotherapy and type of surgery on the likelihood of being sickness absent.

Case-specific potentiation of glioblastoma drugs by pterostilbene
- 2016

Journal article (peer-reviewed)abstract
- Glioblastoma multiforme (GBM, astrocytoma grade IV) is the most common malignant primary brain tumor in adults. Addressing the shortage of effective treatment options for this cancer, we explored repurposing of existing drugs into combinations with potent activity against GBM cells. We report that the phytoalexin pterostilbene is a potentiator of two drugs with previously reported anti-GBM activity, the EGFR inhibitor gefitinib and the antidepressant sertraline. Combinations of either of these two compounds with pterostilbene suppress cell growth, viability, sphere formation and inhibit migration in tumor GBM cell (GC) cultures. The potentiating effect of pterostilbene was observed to a varying degree across a panel of 41 patient-derived GCs, and correlated in a case specific manner with the presence of missense mutation of EGFR and PIK3CA and a focal deletion of the chromosomal region 1p32. We identify pterostilbene-induced cell cycle arrest, synergistic inhibition of MAPK activity and induction of Thioredoxin interacting protein (TXNIP) as possible mechanisms behind pterostilbene's effect. Our results highlight a nontoxic stilbenoid compound as a modulator of anticancer drug response, and indicate that pterostilbene might be used to modulate two anticancer compounds in well-defined sets of GBM patients.

Cancer patients' motives for psychosocial consultation - Oncology social workers' perceptions of 226 patient cases
- 2018
-
In: Psycho-Oncology. - : Wiley. - 1057-9249 .- 1099-1611. ; 27:4, s. 1180-1184

Journal article (peer-reviewed)abstract
- Objective: Although oncology social workers (OSWs) have emerged as a core profession in the provision of psychosocial services, there is a lack of empirical studies that describe their daily clinical work with patients. The overall aim of this study was to explore cancer patients' motives for consulting an OSW.Methods: From a nationwide survey, we used data from 226 patient cases that OSWs met face to face. The OSWs were asked to describe how the case was referred to them, the patient's characteristics, and what they perceived as the patient's motives for contacting them as well as additional motives that came up during the consultations.Results: Patients have different motives for consulting an OSW, and these motives change over the course of consultations; while feelings associated with being diagnosed with cancer were often the initial motive, questions associated with moving on in life and dealing with relationships and the overall life situation were added over time.Conclusions: The results show that Swedish OSWs' function is multifaceted and that the initial motives among patients rarely predict the content in consultations over time. Based on the diversity of motives, it seems obvious that OSWs (at least in Sweden) need a broad education in the psychology of counselling. It also seems obvious that even if patients initially were referred by health care staff to the OSW due to psychological reactions to being ill, staff should also be attentive to the fact that relational and socio-economic/juridical issues are of great concern for the patients.

- Objective: Although oncology social workers (OSWs) have emerged as a core profession in the provision of psychosocial services, there is a lack of empirical studies that describe their daily clinical work with next of kin (NOK). The overall aim of this study was to explore NOK's motives for consulting an OSW. This can provide us with insights into what types of skills OSWs need to have in order to fulfil their duties.Methods: From a nationwide survey, we used data from 54 NOK cases that Swedish OSWs met face to face.Results: About half of the motives concerned help in dealing with personal grief connected to the patients' cancer and distressing symptoms, while the other half concerned needs for help in dealing with the position of being the NOK, relationship conflicts, and assistance with socio-economic issues.Conclusions: The motives show that NOK does not just ask for help to come to terms with distress related to the patients' situation. Based on the diversity of motives, we suggest that OSWs (at least in Sweden) need a broad education in counselling psychology. Furthermore, health care personnel need to be attentive to the NOK's own voice and not reduce it to the voice of the patient and the patient's needs in referrals.

Journal article (peer-reviewed)abstract
- Background Previous studies have found depression to be negatively associated with the prognosis of both cardiovascular disease (CVD) and cancer, but this may partly reflect reverse causality. We limited the possibility of reverse causality by measuring depression before the first diagnosis of CVD or cancer.Methods We used an 11% longitudinal random sample of the Finnish population aged 25 years or older who are residents of Finland for at least 1year between 1987 and 2007, with an 80% oversample of those who died during this period. Those who had their first incidence of coronary heart disease (CHD) (n=107966), stroke (n=68685) or cancer (n=113754) between 1998 and 2012 were followed up for cause-specific mortality from the date of diagnosis until the end of 2012. Depression was defined as having antidepressant purchases two to three calendar years before the incidence. Logistic and Cox regression models were used to examine short-term and long-term mortality by depression status.Results Long-term mortality after diagnosis was 1.34 (95% CI 1.25 to 1.44) for CHD, 1.26 (95% CI 1.15 to 1.37) for stroke and 1.10 (95% CI 1.04 to 1.16) for cancer in those who had used antidepressants in two consecutive calendar years as compared with those with no purchases. Short-term mortality from CHD was elevated among persons with depression (OR=1.30; 95%CI 1.06 to 1.61), but no association was found for stroke.Conclusion Pre-existing depression is associated with a worse prognosis of CHD, stroke and cancer. More attention in the healthcare system is needed for patients with chronic diseases who have a history of depression.
