  • MS risk genes are transcriptionally regulated in CSF leukocytes at relapse

    • BACKGROUND: Infiltrating T-helper cells, cytotoxic T-cells, B-cells and monocytes are thought to mediate the damage to myelin, oligodendrocytes and axons in multiple sclerosis (MS), which results in progressive disability. OBJECTIVE: The objective of this paper is to explore gene expression profiles of leukocytes in the cerebrospinal fluid (CSF) compartment of MS patients during relapse. METHODS: Global gene expression was analyzed by DNA microarray analysis of cells in CSF from MS patients and controls, and verifications were performed with real-time polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA). RESULTS: Fifty percent of the recently described risk genes for MS and 28% of non-risk genes were differently expressed in MS patients compared to controls (χ(2)-test, p=7.7 × 10(-5)). Genes involved in T- and NK-cell processes were up-regulated, and genes involved in processes targeting innate immunity or B-cells were down-regulated in MS. Increased expression of EDN1 and CXCL11 and decreased expression of HMOX1 was verified with real-time PCR and increased expression of CXCL13 was verified with ELISA in CSF. CONCLUSION: DNA microarray analysis is useful in identifying differently expressed genes in CSF leukocytes, which may be important in MS in vivo. Our findings suggest that many of the risk genes for MS are differently expressed in the disease-mediating leukocytes that penetrate the blood-brain barrier.

  • Dose-response relationships for an atomized symptom of fecal incontinence after gynecological radiotherapy.
  • 2013
  • Ingår i: Acta oncologica (Stockholm, Sweden). - : Taylor & Francis. - 1651-226X .- 0284-186X. ; 52:4, s. 719-26

    • Purpose. The aim of this study was to investigate what bowel organ and delivered dose levels are most relevant for the development of 'emptying of all stools into clothing without forewarning' so that the related dose-responses could be derived as an aid in avoiding this distressing symptom in the future. Material and methods. Of the 77 gynecological cancer survivors treated with radiotherapy (RT) for gynecological cancer, 13 developed the symptom. The survivors were treated between 1991 and 2003. The anal-sphincter region, the rectum, the sigmoid and the small intestines were all delineated and the dose-volume histograms were exported for each patient. The dose-volume parameters were estimated fitting the data to the Relative Seriality (RS), the Lyman and the generalized Equivalent Uniform Dose (gEUD) model. Results. The dose-response parameters for all three models and four organs at risk (OARs) were estimated. The data from the sigmoid fits the studied models best: D50 was 58.8 and 59.5 Gy (RS, Lyman), γ50 was 1.60 and 1.57 (RS, Lyman), s was 0.32, n was 0.13 and a was 7.7 (RS, Lyman, gEUD). The estimated volume parameters indicate that the investigated OARs behave serially for this endpoint. Our results for the three models studied indicate that they have the same predictive power (similar LL values) for the symptom as a function of the dose for all investigated OARs. Conclusions. In our study, the anal-sphincter region and sigmoid fit our data best, but all OARs were found to have steep dose-responses for 'emptying of all stools into clothing without forewarning' and thus, the outcome can be predicted with an NTCP model. In addition, the dose to the four studied OARs may be considered when minimizing the risk of the symptom.

  • Perception of body odor-an overlooked consequence of long-term gastrointestinal and urinary symptoms after radiation therapy for prostate cancer.
  • 2013
  • Ingår i: Journal of cancer survivorship : research and practice. - : Springer Science and Business Media LLC. - 1932-2267. ; 7:4, s. 652-658
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose This study was conducted to investigate the association of long-term gastrointestinal and urinary symptoms with perceived fecal or urine body odor after radiation therapy for prostate cancer and its effect on survivors’ quality of life. Methods We used a study-specific questionnaire to measure the occurrence of long-term gastrointestinal and urinary symptoms, the perception of fecal or urine body odor, and quality of life (QoL) 2 to 14 years after radiation therapy for prostate cancer. The questionnaire was sent to 895 eligible survivors who assessed symptom occurrence and QoL in the previous 6 months. Results We received a filled-in questionnaire from 874 (89 %) men. For the long-term gastrointestinal symptoms, 11/13 were associated with the perception of fecal body odor. For the long-term urinary symptoms, 11/11 were associated with the perception of urine body odor. Men who perceived fecal or urine body odor had a lower quality of life, a lower physical health, and more frequent feelings of depression compared with those who did perceive such body odor. Conclusion Long-term gastrointestinal and urinary symptoms after prostate irradiation are associated with the perception of fecal or urine body odor leading to a reduced quality of life. Implications for cancer survivors Disabling body odor after pelvic irradiation needs to be acknowledged in the clinic. Interventions to prevent long-term symptoms may serve the benefit of avoiding fecal or urine body odor after radiation therapy for prostate cancer.

  • Patient-reported genitourinary toxicity for long-term prostate cancer survivors treated with radiation therapy.
  • 2013
  • Ingår i: British journal of cancer. - : Springer Science and Business Media LLC. - 1532-1827 .- 0007-0920. ; 108:10, s. 1964-70
  • Tidskriftsartikel (refereegranskat)abstract
    • Background:The objective of this study is to provide comprehensive overviews of patient-reported urinary symptoms for long-term prostate cancer survivors treated with radiation therapy and for untreated, healthy men.Methods:We performed a population-based cross-sectional study using a study-specific postal questionnaire assessing symptoms among 1007 men consecutively treated at the Sahlgrenska University Hospital, Göteborg, Sweden from 1993-2006 (primary or salvage external beam radiation therapy (EBRT) or EBRT and high-dose rate brachytherapy). We also randomly recruited 350 non-pelvic-irradiated matched control men from the Swedish Total Population Register. Symptom prevalence and prevalence ratios were computed.Results:Survey participation rate was 89% (874/985) for eligible survivors and 73% (243/332) for eligible controls. Median time from treatment to follow-up was 5 years (range, 1-14 years). Among the 21 investigated symptoms reflecting obstruction, frequency, urgency, pain and incontinence, we found significantly higher prevalence compared with controls for 9 symptoms in the EBRT group, 10 in the EBRT+brachytherapy group and 5 in the salvage EBRT group. The prevalence for a majority of the symptoms was stable over time.Conclusion:The presented toxicity profiles provide a thorough understanding of patient-reported urinary symptoms that can assist in developing personalised therapy for prostate cancer.
