- To find out what organs and doses are most relevant for 'radiation-induced urgency syndrome' in order to derive the corresponding dose-response relationships as an aid for avoiding the syndrome in the future.From a larger group of gynecological cancer survivors followed-up 2-14 years, we identified 98 whom had undergone external beam radiation therapy but not brachytherapy and not having a stoma. Of those survivors, 24 developed urgency syndrome. Based on the loading factor from a factor analysis, and symptom frequency, 15 symptoms were weighted together to a score interpreted as the intensity of radiation-induced urgency symptom. On reactivated dose plans, we contoured the small intestine, sigmoid colon and the rectum (separate from the anal-sphincter region) and we exported the dose-volume histograms for each survivor. Dose-response relationships from respective risk organ and urgency syndrome were estimated by fitting the data to the Probit, RS, LKB and gEUD models.The rectum and sigmoid colon have steep dose-response relationships for urgency syndrome for Probit, RS and LKB. The dose-response parameters for the rectum were D50: 51.3, 51.4, and 51.3 Gy, γ50 = 1.19 for all models, s was 7.0e-09 for RS and n was 9.9 × 107 for LKB. For Sigmoid colon, D50 were 51.6, 51.6, and 51.5 Gy, γ50 were 1.20, 1.25, and 1.27, s was 2.8 for RS and n was 0.079 for LKB.Primarily the dose to sigmoid colon as well as the rectum is related to urgency syndrome among gynecological cancer survivors. Separate delineation of the rectum and sigmoid colon in order to incorporate the dose-response results may aid in reduction of the incidence of the urgency syndrome.

Tidskriftsartikel (refereegranskat)abstract
- Background. Cervical cancer screening (CCS) using Pap-smears has been carried out for decades and is still an essential tool for secondary cancer prevention. Focus has traditionally been on what hinders women's attendance, instead of researching this issue from a positive standpoint, i.e. what factors encourage women to take a Pap-smear? In this article, we therefore explore issues that 30-year-old women have addressed as encouraging CCS attendance, with particular focus on aspects susceptible to intervention. Material and methods. Through the population-based cervical cancer screening (PCCSP) registry in Stockholm, Sweden, a stratified random sampling technique was used to recruit women from the same birth cohort with varied CCS histories and results. Nine face-to-face focus groups discussions (FGDs) and 30 internet-based FGDs were conducted with a total of 138 women aged 30. Qualitative analysis was inspired by interpretative description, to generate clinically relevant and useful data. Results. In general, these women expressed positive views about the PCCSP as an existing service, regardless of screening history. They described a wide range of factors encompassing the entire screening trajectory from invitation through follow-up which could motivate young women to CCS participation, including social marketing. Many of the suggestions related to individualization of the PCCSP, as well as a need to understand the relationship between human papilloma virus (HPV) and cervical cancer. Discusssion. These results are discussed in terms of the inherent tension between population-based public health initiatives and individually-oriented health care provision. Many suggestions given are already incorporated into the existing Stockholm-Gotland screening program, although this information may not reach women who need it. New research should test whether systematic information on HPV may provide a missing link in motivating young women to attend CCS, and which of their suggestions can serve to increase CCS participation.

Teenagers want to be told when a parent's death is near: A nationwide study of cancer-bereaved youths' opinions and experiences.
- 2015

Tidskriftsartikel (refereegranskat)abstract
- Background. We aimed to investigate cancer-bereaved youths' opinions and experiences of being told about a parent's imminent death from cancer and of barriers to this communication. Material and methods. This nationwide population-based survey included 622/851 (73%) youths (aged 18-26) who at age 13-16, 6-9 years earlier had lost a parent to cancer. Results. In total 595 of 610 (98%) of the participants stated that teenage children should be informed when the parent's death was imminent (i.e. a matter of hours or days, not weeks). 59% stated that they themselves had been told this, 37% by the parents, 7% by parents and healthcare professionals together and 8% by professionals only. Frequent reasons for why the teenager and parents did not talk about imminent death before loss were that one (n = 106) or both (n = 25) of the parents together with the teenage child had pretended that the illness was not that serious, or that none of the parents had been aware that death was imminent (n = 80). Up to a couple of hours before the loss, 43% of participants had not realized that death was imminent. Conclusion. In this population-based study virtually all youth who at ages 13-16 had lost a parent to cancer afterwards stated that teenagers should be told when loss is near, i.e. a matter of hours or days, not weeks. Many stated that they had not been given this information and few were informed by professionals, with implications for future improvements in end-of-life care of patients with teenage children.

Tidskriftsartikel (refereegranskat)abstract
- The Multidimensional Fatigue Inventory (MFI-20) scale is widely used for measuring fatigue in cancer care. This questionnaire has been translated into Swedish and used in Swedish cancer populations, and the aim of this study was to test the validity and reliability of the Swedish version in four populations, with a total of 584 patients. The participants were classified into four groups: palliative cancer patients, cancer patients receiving radiation therapy, non-cancer outpatients, and a group of hospital staff. The MFI-20 consists of five subscales of fatigue: General Fatigue (GF), Physical Fatigue (PF), Reduced Motivation (RM), Reduced Activity (RA) and Mental Fatigue (MF). We have tested the convergent validity of the MFI-20 using the Category Ratio instrument (CR-10). The validity and the reliability of MFI-20 were acceptable. All subscales of the MFI-20 were correlated, and all were also correlated with the CR-10 score (p <= 0.001). General Fatigue was highly correlated with Physical Fatigue for the three patient groups, but this was not the fact for healthy staff. Deleting some items increased Cronbach's alpha of the subscale to which these items belonged (where alpha measures the reliability of the results). The level of non-response was low (less than 1.2%) and there was no pattern to the items omitted. We conclude that the MFI-20 is a valid and reliable instrument for measuring fatigue in patients and in healthy individuals. The results support, to some extent, earlier findings and one item can be removed from the Swedish version of the MFI-20.

Tidskriftsartikel (refereegranskat)abstract
- In Sweden from 1980 to 1995 there was an overall decrease of 56% in mean length of stay (MLOS) for surgical curative breast cancer treatment. The objective of this study was to separate the possible impact of tumour size and lymph node dissemination and changes in surgical procedures. All women diagnosed (n=13 290) with breast cancer between 1982 and 1995 were selected from the Southern Swedish Tumour Register. Data on LOS, diagnoses, and surgical procedures were obtained from the Swedish Hospital Discharge Register. A multi-factorial model was fitted to the data. Discharges where patients were treated with breast conserving surgery had more than two days shorter MLOS (-2.49, 95% CI -1.66) compared with mastectomy. Although TNM data imply a shift from T2 to smaller T1 among operated women the effect on MLOS is negligible when controlled for age, type of operation etc. Changes in clinical practice such as changes in operation technique can explain approximately 13% of the total decrease in MLOS.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Cancer stage at diagnosis is the most important prognostic factor for lung cancer (LC), but most patients are diagnosed with advanced disease with many and intense symptoms. This study explores relationships between LC patients' first symptoms, symptoms triggering health care system (HCS) contact, demographic/clinical characteristics, and time spans in the care trajectory from first symptom(s) to treatment start.MATERIALS AND METHODS: Medical records were examined from all 314 patients diagnosed with primary LC in 2003 at a Department of Respiratory Medicine, in Stockholm Sweden. Descriptive analysis was used to examine symptoms and time spans in the care trajectory. Cox regression analysis was conducted to explore the influence of symptoms and demographic/clinical characteristics on the time spans.RESULTS: Tumor-specific symptoms led to HCS visits to a greater extent than did systemic symptoms, despite reports of weight loss, fatigue and appetite loss as common first symptoms. Minor differences between women and men were found regarding specific symptoms. The study confirms that the time spans from first symptoms reported to treatment start are extensive, exceeding Swedish national recommendations. A lump/resistance, neurological symptoms, appetite loss, hemoptysis and non-thoracic related pain were associated with significantly shorter time spans in the care trajectory. People >74 years old risked longer time span from first HCS visit to treatment start.CONCLUSION: This study indicates a need for a more efficient LC care trajectory. Elderly patients could be particularly vulnerable for longer time spans.

Are there any positive consequences of childhood cancer? : A review of the literature
- 2008
-
Ingår i: Acta Oecologica. - : Informa UK Limited. - 1146-609X .- 1873-6238 .- 0284-186X .- 1651-226X. ; 47:2, s. 199-206

Forskningsöversikt (refereegranskat)abstract
- The aim was to investigate whether there are any positive consequences of childhood cancer. Studies published 1990-2005 reporting survivors' descriptions of positive consequences of childhood cancer were identified through a search in the databases CINAHL, PsycINFO, and PubMed. According to a manifest content analysis, positive consequences were referred to three themes: life values, relations to others, and relation to self. A second search in the same databases was conducted to identify studies investigating whether survivors of childhood cancer differ from comparison groups with regard to variables assigned to these themes. In these studies, no conclusions about positive consequences with regard to the theme life values can be drawn, as only one study was identified. In addition, only a small minority of findings from comparative studies indicate that childhood cancer has any positive consequences with regard to relations to others and relation to self. A majority of the results indicate that survivors do not differ from comparison groups, whereas some findings highlight that friendship and marital status are areas of concern, and parenthood and sexuality are areas of potential concern. It is recommended that survivors of childhood cancer are followed up by a multi-professional team, focusing not only on the survivors' health status but also on relations to family, friends, and partners.

Measuring anxiety and depression in the oncology setting using visual-digital scales.
- 2007
-
Ingår i: Acta oncologica (Stockholm, Sweden). - : Informa UK Limited. - 0284-186X .- 1651-226X. ; 46:6, s. 810-6

Tidskriftsartikel (refereegranskat)abstract
- We investigated the feasibility of using single-item visual-digital scales for measuring anxiety and depression for research purposes within the oncology and palliative care setting. Data were retrieved from five nationwide postal questionnaires comprising 3030 individuals (response rate 76%): cancer patients, widows/parents who had lost their husband/child to cancer and population controls. All questionnaires contained the Center for Epidemiological Studies Depression scale (CES-D) and Spielberger's State-Trait Anxiety Inventory (STAI-T) as well as seven-point Visual-Digital Scales (VDS) assessing anxiety and depression. Each stepwise increased score on the VDS-depression provided a statistically significant increase in the mean score on CES-D (Spearman's r=0.582). The VDS-anxiety correlated with mean scores on STAI-T (Spearman's r=0.493), however, not all stepwise increased scores on the VDS-anxiety gave a statistically significant increase on the STAI-T. Positive- and negative predictive values were 51% and 91% for VDS-depression and 64% and 80% for VDS-anxiety. Missing data for STAI-T were 7% and 9% for CES-D; the corresponding figures were 2% for the VDS-depression and 3% for VDS-anxiety. With low attrition and agreement with psychometric scales, the Visual-Digital Scales are a feasible alternative for research in the oncology setting. However, the high negative predictive value and the low positive predictive value suggest that the visual- digital scales mainly detect the absence of the symptoms.
