    • Leukemic cells from 85 children with newly diagnosed precursor B-lineage ALL were tested for in vitro drug sensitivity to a panel of anti-cancer drugs. Minimal residual disease (MRD) was measured by RQ-PCR. There was a significant correlation between MRD day 29 and in vitro sensitivity to prednisolone (p<0.001) and doxorubicin (p=0.017), drugs administered during induction therapy. In patients with t(12;21) (n=20), in vitro sensitivity to doxorubicin was an independent factor for MRD <0.1% (p=0.031; R(2)=0.66). Thus, data show that in vitro drug sensitivity at diagnosis is correlated to cell kill during induction therapy as measured by MRD day 29.

  • Weight and body mass index in relation to irradiated volume and to overall survival in patients with oropharyngeal cancer: a retrospective cohort study
  • 2014
  • Ingår i: Radiation Oncology. - BioMed Central. - 1748-717X. ; 9
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Weight loss is a common problem in patients with Squamous Cell Carcinoma of the Head and Neck (SCCHN) treated with radiotherapy (RT). The aims of the present study were to determine if treated volume (TV), as a measure of the radiation dose burden, can predict weight loss in patients with oropharyngeal cancer and to analyze weight loss and body mass index (BMI) in the same patient group in relation to 5-year overall survival. Methods: The ARTSCAN trial is a prospective, randomized, multicenter trial in patients with SCCHN. Nutritional data from the ARTSCAN trial were analyzed retrospectively using univariate and multivariate statistical methods based on information on percentage weight loss from the start of RT up to five months after the termination of RT (study cohort 1, n = 232) and information on patients' BMI at the start of RT (study cohort 2, n = 203). TV was defined as the volume of the patient receiving at least 95% of the prescribed dose. TV64.6 (Gy) encompasses macroscopic tumor and TV43.7 (Gy) elective lymph nodes of the neck. Results: TV64.6 Gy and TV43.7 Gy were both significantly correlated with higher weight loss up to five months after the termination of RT in study cohort 1 (p < 0.001 for both). BMI at the start of RT was shown to be a prognostic factor for 5-year overall survival in study cohort 2 but weight loss was not. The hazard ratios and 95% confidence intervals were 3.78 (1.46-9.75) and 2.57 (1.43-4.62) in patients with underweight and normal weight, respectively. Conclusions: TV can predict weight loss during RT in patients with oropharyngeal cancer regardless of clinical stage. A high BMI (>25 kg/m(2)) at the start of RT is positively associated with survival in patients with oropharyngeal cancer.

  • Anxiety is contagious-symptoms of anxiety in the terminally ill child affect long-term psychological well-being in bereaved parents.
  • 2010
  • Ingår i: Pediatric blood & cancer. - 1545-5017. ; 54:5, s. 751-7
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: We studied the relation between unrelieved symptoms in terminally ill children and the psychological well-being in the bereaved parents 4-9 years after their loss.PROCEDURE: We contacted parents in Sweden who had lost a child to a malignancy 1992-1997. The parents were asked to assess symptoms affecting their child's well-being during his or her last month of life, and their own current psychological well-being.RESULTS: Altogether 449/561 (80%) eligible parents supplied information on 19 specific symptoms that may occur in children with a malignancy and how each of these symptoms had affected their child's well-being during his or her last month of life (not applicable, none, low, moderate, or severe). These results were linked to questions concerning the parents' self-assessed mental health. Parents of children who were affected by disturbed sleep also had increased risk to develop these symptoms; RR 2.0 [1.4-2.9] for depression, 1.8 [1.3-2.5] for anxiety, 1.5 [1.2-1.8] for decreased psychological well-being, and 1.5 [1.3-1.9] for decreased quality of life.CONCLUSIONS: Bereaved parents whose children were affected by anxiety or disturbed sleep due to anxiety or pain had an increased risk of long-term psychological morbidity. Reducing psychological complications in seriously ill children may also improve the psychological well-being in bereaved parents.

  • Symptoms affecting children with malignancies during the last month of life: a nationwide follow-up
  • 2006
  • Ingår i: Pediatrics. - 1098-4275. ; 117:4, s. 1314-20
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: In a population-based nationwide survey, we aimed to study symptoms in children with malignancies during the last month of their lives. Understanding which symptoms affect children in the terminal phase of disease is crucial to improve palliative care.METHODS: We attempted to contact all parents in Sweden who had lost a child to cancer during a 6-year period. The parents were asked, through an anonymous postal questionnaire, about symptoms that affected the child's sense of well-being during the last month of life.RESULTS: Information was supplied by 449 (80%) of 561 eligible parents. The symptoms most frequently reported with high or moderate impact on the child's well-being were: physical fatigue (86%), reduced mobility (76%), pain (73%), and decreased appetite (71%). Irrespective of the specific malignancy, physical fatigue was the most frequently reported symptom, and pain was among the 3 most frequently reported. Children who died at 9 to 15 years of age were reported to be moderately or severely affected, by a number of symptoms, significantly more often than other children. The gender of the reporting parent had no significant bearing on any of the symptoms reported.CONCLUSIONS: The most frequently reported symptoms in children with malignancies to be aware of and possibly address during the terminal phase are physical fatigue, reduced mobility, pain, and decreased appetite. Children aged 9 to 15 years are reported to be moderately or severely affected by more symptoms than children in other age groups. Mothers and fathers report a similar prevalence of symptoms.

  • Preparatory Studies to a Population-Based Survey of Suicide-Bereaved Parents in Sweden.
  • 2013
  • Ingår i: Crisis. - 0227-5910. ; 34:3, s. 200-210
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: There is a need for evidence-based guidelines on how professionals should act following a suicide. In an effort to provide empiric knowledge, we designed a nationwide population-based study including suicide-bereaved parents.AIM: To describe the process from creating hypotheses through interviews to the development of a population-based questionnaire.METHOD: We used interviews, qualitative analysis and various means of validation to create a study-specific questionnaire to be used in a nonselected nationwide population of suicide-bereaved parents and a control population of nonbereaved (N = 2:1). The Swedish Register of Causes of Death and the Multigeneration Register were used to identify eligible individuals. All presumptive participants received a letter of invitation followed by a personal contact.RESULTS: We developed a questionnaire covering the participants' perception of participation, their daily living, psychological morbidity, professional actions, and other experiences in immediate connection to the time before and after the suicide. Almost three out of four parents (bereaved = 666, nonbereaved = 377) responded to the questionnaire.CONCLUSIONS: By involving parents early in the research process we were able to create a questionnaire that generated a high participation rate in a nationwide population-based study that might help us to answer our hypotheses about bereavement after suicide.

  • They still grieve - a nationwide follow-up of young adults 2-9 years after losing a sibling to cancer
  • 2014
  • Ingår i: Psycho-Oncology. - 1057-9249 .- 1099-1611. ; 23:6, s. 658-664
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: The aims of this study were to assess the prevalence of unresolved grief in bereaved young adult siblings and examine possible contributing factors. Methods: The study was a Swedish population-based study of young adults who had lost a brother or sister to cancer, 2-9 years earlier. Of 240 eligible siblings, 174 (73%) completed a study-specific questionnaire. This study focused on whether the respondents had worked through their grief over the sibling's death and to what extent. Results: A majority (54%) of siblings stated that they had worked through their grief either not at all' or to some extent' at the time of investigation. In multiple regression analyses with unresolved grief as the dependent variable, 21% of the variance was explained by lack of social support and shorter time since loss. Conclusion: The majority of bereaved young adults had not worked through their grief over the sibling's death. A small group of siblings reported that they had not worked through their grief at all, which may be an indicator of prolonged grief. Lack of social support and more recent loss were associated with not having worked through the grief over the sibling's death.

  • Inflammatory and metabolic biomarkers and risk of liver and bilary tract cancer
  • 2014
  • Ingår i: Hepatology. - Wiley-Blackwell. - 0270-9139. ; 60:3, s. 858-871
  • Tidskriftsartikel (refereegranskat)abstract
    • Obesity and associated metabolic disorders have been implicated in liver carcinogenesis; however there is little data on the role of obesity-related biomarkers on liver cancer risk. We studied prospectively the association of inflammatory and metabolic biomarkers with risks of hepatocellular carcinoma (HCC), intra-hepatic bile duct (IBD) and gallbladder and bilary tract cancers outside of the liver (GBTC) in a nested case-control study within the European Prospective Investigation into Cancer and Nutrition (EPIC). Over an average of 7.7 years, 296 participants developed HCC (n=125), GBTC (n=137) or IBD (n=34). Using risk set sampling, controls were selected in a 2:1 ratio and matched for recruitment center, age, sex, fasting status, time of blood collection. Baseline serum concentrations of C-reactive protein (CRP), interleukin-6 (IL-6), C-peptide, total, high-molecular-weight (HMW) adiponectin, leptin, fetuin-a, and glutamatdehydrogenase (GLDH) were measured and incidence rate ratios (IRRs) and 95% confidence intervals (CI-s) estimated using conditional logistic regression. After adjustment for lifestyle factors, diabetes, hepatitis infection and adiposity measures, higher concentrations of CRP, IL-6, C-peptide and non-HMW adiponectin were associated with higher risk of HCC (IRR per doubling of concentrations = 1.22; 95%CI = 1.02-1.46, P=0.03; 1.90; 95%CI = 1.30-2.77, P=0.001; 2.25; 95%CI = 1.43-3.54, P=0.0005 and 2.09; 95%CI = 1.19-3.67, P=0.01, respectively). CRP was associated also with risk of GBTC (IRR = 1.22; 95%CI = 1.05-1.42, P=0.01). GLDH was associated with risks of HCC (IRR = 1.62; 95%CI = 1.25-2.11, P=0.0003) and IBD (IRR = 10.5; 95%CI = 2.20-50.90, P=0.003). The continuous net reclassification index was 0.63 for CRP, IL-6, C-peptide and non-HMW adiponectin, and 0.46 for GLDH indicating good predictive ability of these biomarkers. Conclusion: Elevated levels of biomarkers of inflammation and hyperinsulinemia are associated with a higher risk of HCC, independent of obesity and established liver cancer risk factors.
