[Chronic graft-versus-host disease]. / Kronisk transplantat-mot-vert-sykdom.

Chronic graft-versus-host disease is a late complication of allogeneic stem cell transplantation and leads to chronic inflammation and fibrosis in various organs due to dysregulation of donor immune cells. The disease can occur in all organs, but is most frequently seen in the skin, eyes, oral cavity, gastrointestinal tract, genitalia, lungs, muscles, fascia and joints. Chronic graft-versus-host disease is associated with considerable morbidity and mortality, and treatment requires close collaboration between different parts of the specialist health services. This article provides a clinical review of chronic graft-versus-host disease based on a non-systematic literature search and the authors' own clinical experience.

Allogeneic stem cell transplantation in adults 2015-21. / Allogen stamcelletransplantasjon hos voksne 2015­21.

BACKGROUND: Allogeneic stem cell transplantation is the only curative treatment for several malignant and non-malignant haematological diseases, and is associated with a risk of serious complications. In recent years, several changes have been introduced with the aim of reducing treatment-related complications. This retrospective study reviews quality indicators for patients who underwent transplantation in the period 2015-21. MATERIAL AND METHOD: The study included 589 adult patients who were treated with allogeneic stem cell transplantation for the first time at Oslo University Hospital in the period May 2015 to May 2021. Three two-year periods are compared using descriptive methods. RESULTS: In the period 2015-2021, the number of first-time transplant patients per year increased from 85 to 113. One-year survival increased from 68 % in the first two-year period to 74 % in the second period and 82 % in the last period. Both acute and chronic GVHD were reduced, and one-year GVHD-free and relapse-free survival increased from 42 % to 60 % during the study period. INTERPRETATION: Since 2015, the number of transplants has increased, while survival has improved and the risk of complications is lower.

Improved outcome in patients following autologous stem cell transplantation for multiple myeloma in south eastern Norway 2001-2010: a retrospective, population based analysis.

BACKGROUND: With the advent of novel drugs improved overall survival in patients with multiple myeloma, including patients who received up-front autologous stem cell transplantation (ASCT), has been reported from several centers. Here we report on overall survival in a population-based cohort of patients receiving ASCT as first line treatment and in whom novel agents were an option for second and later lines of treatment. METHODS: Patients with multiple myeloma ≤ 65 years of age who were considered for ASCT from 01.01.2001-31.06.2005 (period 1) and from 01.07.2005 until 31.12.2009 (period 2) at Oslo University Hospital (OUH) were identified. Relevant data were collected from the patients' medical records. RESULTS: Altogether, 293/355 patients received ASCT. In all, median OS was 82.9 months in patients ≤ 60 years of age and 59.0 months in patients 61-65 years. For patients ≤ 60 years of age median OS increased from 70.6 months to 87.7 months (p = 0. 22) and median survival after start of second line therapy increased from 34.5 months to 46.5 months (p = 0.015) between the two periods. For patients 61-65 years of age median OS increased from 57.3 months to 61.2 months (p = 0. 87) and median survival after start of second line therapy was practically unchanged (32.6 months vs. 33.1 months (p = 0.97) between the periods. In patients ≤ 60 years of age salvage ASCT was used in 34% of the patients while in patients 61-65 years of age salvage ASCT was used in 7.3% of the patients. The use of salvage ASCT and novel drugs, as well as the number of treatment lines, were higher in patients ≤ 60 years of age and increased during the study period. CONCLUSION: In patients ≤ 60 years of age an increased median OS of 17 months between the two periods were noted, but the difference failed to reach statistical significance. However, a statistically significant difference in median survival of 12 months after start of second line therapy was found in this age group, which may be explained by a more active second line treatment. In patients 61-65 years only a slight increase of survival, not statistically significant, was noted between the periods.
