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."

- Background and objective. The aim of this study was to describe what factors of the healthcare environment are perceived as being important to patients in oncology care. Setting and participants. The sample was 11 patients with different cancer diagnoses in an oncology ward at a university hospital in west Sweden. Results. Analysis of the patients' perceptions of the environment indicated a complex entity comprising several aspects. These came together in a structure consisting of three main categories: safety, partnership with the staff, and physical space. The care environment is perceived as a complex entity, made up of several physical and psychosocial aspects, where the physical factors are subordinated by the psychosocial factors. It is clearly demonstrated that the patients' primary desire was a psychosocial environment where they were seen as a unique person; the patients wanted opportunities for good encounters with staff, fellow patients, and family members, supported by a good physical environment; and the patients valued highly a place to withdraw and rest. Conclusions. This study presents those attributes that are valued by cancer patients as crucial and important for the support of their well-being and functioning. The results show that physical aspects were subordinate to psychosocial factors, which emerged strongly as being the most important in a caring environment.

Novel Circulating and Tissue Biomarkers for Small Intestine Neuroendocrine Tumors and Lung Carcinoids
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Small intestine neuroendocrine tumors (SI-NETs) and lung carcinoids (LCs) are relatively indolent tumors, which originate from neuroendocrine (NE) cells of the diffuse NE system. Metastases can spread before diagnosis. Thus, potential cures become unavailable, which entitles new biomarker development. Indeed, we aimed at developing Ma2 autoantibodies and olfactory receptor 51E1 (OR51E1) as potential novel biomarkers and exploring other candidate protein markers in patients’ serum.First, we established a sensitive, specific and reliable anti-Ma2 indirect ELISA to distinguish SI-NET patients from healthy controls. We detected longer progression-free and recurrence-free survivals in patients expressing low anti-Ma2 titers. Moreover, a high anti-Ma2 titer was more sensitive than chromogranin A for the risk of recurrence after radical operation of SI-NET patients.We then investigated OR51E1 expression in SI-NETs and LCs. OR51E1 mRNA expression, analyzed by quantitative real-time PCR, was high in microdissected SI-NET cells, in LC cell lines and in frozen LC specimens. Immunohistochemistry (IHC) showed abundant OR51E1 protein expression in SI-NETs. OR51E1 co-expressed with vesicular-monoamine-transporter-1 in the majority of normal and neoplastic enterochromaffin cells.Furthermore, the study on LCs revealed that OR51E1, somatostatin receptor (SSTR) 2, SSTR3, and SSTR5 are expressed in 85%, 71%, 25% and 39% of typical carcinoids (TCs), whereas in 86%, 79%, 43% and 36% of atypical carcinoids (ACs). Based on the proposed IHC scoring system, in the LC cases, where all SSTR subtypes were absent, membrane OR51E1 expression was detected in 10 out of 17 TCs and 1 out of 2 ACs. Moreover, higher OR51E1 scores were detected in 5 out of 6 OctreoScan-negative LC lesions.In addition, the last presented study used a novel suspension bead array, which targeted 124 unique proteins, by using Human Protein Atlas antibodies, to profile biotinylated serum samples from SI-NET patients and healthy controls. We showed 9 proteins, IGFBP2, IGF1, SHKBP1, ETS1, IL1α, STX2, MAML3, EGR3 and XIAP as significant contributors to tumor classification.In conclusion, we proposed Ma2 autoantibodies as a sensitive circulating marker for SI-NET recurrence; OR51E1 as a candidate therapeutic target for SI-NETs; whereas as a novel diagnostic marker for LCs and 9 serum proteins as novel potential SI-NET markers.

- A few studies have indicated that parents' reactions to a child's serious disease may entail long-term stress for the parents. However, further knowledge of its consequences is valuable. The aim of the study was to investigate the occurrence of burnout in a Swedish national sample of parents of children who had undergone HSCT and survived. Burnout (Shirom-Melamed Burnout Questionnaire) and estimations of the child's health status (Lansky/Karnofsky estimations and study-specific questions) were self-reported by 159 mothers and 123 fathers. In addition, physicians made estimations of the child's health status (Lansky/Karnofsky estimations). Nonparametric tests revealed that burnout symptoms occurred more often among fathers of children who had undergone transplantation within the last five yr compared to fathers of children with no history of serious disease (34.4% vs. 19.9%). Burnout among mothers and fathers was associated with the child's number and severity of health impairments up to five yr after the child underwent HSCT (Spearman's rho for mothers 0.26-0.36 and for fathers 0.36-0.61). In conclusion, chronic stress in parents after a child's HSCT seems to abate eventually. However, parents should be monitored and offered adequate support when needed. Moreover, the situation of fathers in the often mother-dominated pediatric setting should receive more attention in research as well as in the clinic.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND & AIMS: Few modifiable risk factors have been implicated in the etiology of pancreatic cancer. There is little evidence for the effects of caffeinated coffee, decaffeinated coffee, or tea intake on risk of pancreatic cancer. We investigated the association of total coffee, caffeinated coffee, decaffeinated coffee, and tea consumption with risk of pancreatic cancer.METHODS: This study was conducted within the European Prospective Investigation into Nutrition and Cancer cohort, comprising male and female participants from 10 European countries. Between 1992 and 2000, there were 477,312 participants without cancer who completed a dietary questionnaire, and were followed up to determine pancreatic cancer incidence. Coffee and tea intake was calibrated with a 24-hour dietary recall. Adjusted hazard ratios (HRs) were computed using multivariable Cox regression.RESULTS: During a mean follow-up period of 11.6 y, 865 first incidences of pancreatic cancers were reported. When divided into fourths, neither total intake of coffee (HR, 1.03; 95% confidence interval [CI], 0.83-1.27; high vs low intake), decaffeinated coffee (HR, 1.12; 95% CI, 0.76-1.63; high vs low intake), nor tea were associated with risk of pancreatic cancer (HR, 1.22, 95% CI, 0.95-1.56; high vs low intake). Moderately low intake of caffeinated coffee was associated with an increased risk of pancreatic cancer (HR, 1.33; 95% CI, 1.02-1.74), compared with low intake. However, no graded dose response was observed, and the association attenuated after restriction to histologically confirmed pancreatic cancers.CONCLUSIONS: Based on an analysis of data from the European Prospective Investigation into Nutrition and Cancer cohort, total coffee, decaffeinated coffee, and tea consumption are not related to the risk of pancreatic cancer.

Tidskriftsartikel (refereegranskat)abstract
- The 309T>G polymorphism in the promoter region of the MDM2gene, known as SNP309, has recently been suggested as an unfavorable prognostic marker in chronic lymphocytic leukemia (CLL) although this has been questioned. To investigate this further, we analyzed the MDM2 SNP309 genotypes in 418 CLL patients and correlated the results with established CLL prognostic factors, time to treatment and overall survival. In this Swedish cohort, no association existed between any particular MDM2 SNP309 genotype, overall survival and time to treatment. Furthermore, no correlation was shown between the MDM2 SNP309 genotypes and Binet stage, IGHV mutational status and recurrent genomic aberrations. In summary, this study argues against the use of the MDM2 SNP309 as a prognostic marker in CLL.

- Background: The type and quantity of dietary carbohydrate as quantified by glycemic index (GI) and glycemic load (GL), and dietary fiber may influence the risk of liver and biliary tract cancers, but convincing evidence is lacking. Patients and methods: The association between dietary GI/GL and carbohydrate intake with hepatocellular carcinoma (HCC; N = 191), intrahepatic bile duct (IBD; N = 66), and biliary tract (N = 236) cancer risk was investigated in 477 206 participants of the European Prospective Investigation into Cancer and Nutrition cohort. Dietary intake was assessed by country-specific, validated dietary questionnaires. Hazard ratios and 95% confidence intervals were estimated from proportional hazard models. HBV/HCV status was measured in a nested case-control subset. Results: Higher dietary GI, GL, or increased intake of total carbohydrate was not associated with liver or biliary tract cancer risk. For HCC, divergent risk estimates were observed for total sugar = 1.43 (1.17-1.74) per 50 g/day, total starch = 0.70 (0.55-0.90) per 50 g/day, and total dietary fiber = 0.70 (0.52-0.93) per 10 g/day. The findings for dietary fiber were confirmed among HBV/HCV-free participants [0.48 (0.23-1.01)]. Similar associations were observed for IBD [dietary fiber = 0.59 (0.37-0.99) per 10 g/day], but not biliary tract cancer. Conclusions: Findings suggest that higher consumption of dietary fiber and lower consumption of total sugars are associated with lower HCC risk. In addition, high dietary fiber intake could be associated with lower IBD cancer risk. © The Author 2012. Published by Oxford University Press on behalf of the European Society for Medical Oncology.

- Consumption of fruits and vegetables is associated with a lower overall mortality. The aim of this study was to identify causes of death through which this association is established. More than 450,000 participants from the European Prospective Investigation into Cancer and Nutrition study were included, of which 25,682 were reported deceased after 13 years of follow-up. Information on lifestyle, diet and vital status was collected through questionnaires and population registries. Hazard ratios (HR) with 95 % confidence intervals (95 % CI) for death from specific causes were calculated from Cox regression models, adjusted for potential confounders. Participants reporting consumption of more than 569 g/day of fruits and vegetables had lower risks of death from diseases of the circulatory (HR for upper fourth 0.85, 95 % CI 0.77-0.93), respiratory (HR for upper fourth 0.73, 95 % CI 0.59-0.91) and digestive system (HR for upper fourth 0.60, 95 % CI 0.46-0.79) when compared with participants consuming less than 249 g/day. In contrast, a positive association with death from diseases of the nervous system was observed. Inverse associations were generally observed for vegetable, but not for fruit consumption. Associations were more pronounced for raw vegetable consumption, when compared with cooked vegetable consumption. Raw vegetable consumption was additionally inversely associated with death from neoplasms and mental and behavioral disorders. The lower risk of death associated with a higher consumption of fruits and vegetables may be derived from inverse associations with diseases of the circulatory, respiratory and digestive system, and may depend on the preparation of vegetables and lifestyle factors. © 2014 Springer Science+Business Media Dordrecht.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To explore the influence of symptom clusters and the most distressing concerns on global rating of quality of life (QoL) among patients with inoperable lung cancer (LC) over a three-month period following diagnosis. Methods: Data were derived from a longitudinal study dealing with the symptom experiences of 400 patients with LC at three time points: close to diagnosis and one and three months later. The symptom clusters were derived from a QoL questionnaire using factor analysis, which resulted in three clusters: the Respiratory cluster, the Pain cluster and the Mood cluster. The most distressing concerns were derived from responses to a free listing question (What is most distressing at present') and were categorised under three dimensions: Bodily distress, Life situation with LC and latrogenic distress. Cross-sectional, multivariate regression analyses with QoL as a dependent variable were used to determine predictors (Symptom clusters and most distressing concerns) at the three time points. Results: All three symptom clusters predicted QoL at each time point. Close to diagnosis, none of the dimensions of most distressing concerns predicted QoL, while the dimension Bodily distress was a significant predictor of QoL after one month. The Life situation with LC dimension was a significant predictor of QoL three months after diagnosis. Conclusions: Symptom clusters are important to LC patients' QoL and need to be acknowledged by healthcare professionals. The present study shows the importance of patients' descriptions of key concerns, which vary from diagnosis onwards, and urges healthcare professionals to be vigilant to such changes.
