  • Time trends, improvements and national auditing of rectal cancer management over an 18-year period
  • 2015
  • Ingår i: Colorectal Disease. - 1462-8910 .- 1463-1318. ; 17:9, s. O168-O179
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: The main aims were to explore time trends in the management and outcome of patients with rectal cancer in a national cohort and to evaluate the possible impact of national auditing on overall outcomes. A secondary aim was to provide population-based data for appraisal of external validity in selected patient series.Method: Data from the Swedish ColoRectal Cancer Registry with virtually complete national coverage were utilized in this cohort study on 29925 patients with rectal cancer diagnosed between 1995 and 2012. Of eligible patients, nine were excluded.Results: During the study period, overall, relative and disease-free survival increased. Postoperative mortality after 30 and 90days decreased to 1.7% and 2.9%. The 5-year local recurrence rate dropped to 5.0%. Resection margins improved, as did peri-operative blood loss despite more multivisceral resections being performed. Fewer patients underwent palliative resection and the proportion of non-operated patients increased. The proportions of temporary and permanent stoma formation increased. Preoperative radiotherapy and chemoradiotherapy became more common as did multidisciplinary team conferences. Variability in rectal cancer management between healthcare regions diminished over time when new aspects of patient care were audited.Conclusion: There have been substantial changes over time in the management of patients with rectal cancer, reflected in improved outcome. Much indirect evidence indicates that auditing matters, but without a control group it is not possible to draw firm conclusions regarding the possible impact of a quality control registry on faster shifts in time trends, decreased variability and improvements. Registry data were made available for reference.

  • A template for writing radiotherapy protocols.
  • 2015
  • Ingår i: Acta Oncologica. - Taylor & Francis. - 1651-226X. ; 54:2, s. 275-279
  • Tidskriftsartikel (refereegranskat)abstract
    • Background. Well-specified and unambiguous treatment protocols are essential both for current practice and for the future development of radiation therapy. In order to provide assistance for writing good protocols, irrespective of treatment intention and complexity, up-to-date guidelines are highly desirable. Methods. We have analysed the radiotherapy work-flow, including clinical and physical aspects, such as preparatory imaging, treatment planning, delivery and evaluation, with the aim to outline a consistent framework covering the entire radiotherapy process. Results. Based on the analysis, a recipe-style template for specifying the description of the radiotherapy process has been designed. The template is written in a general format, which allows for modified phrasing, and should be customised for the specific clinical situation and diagnosis, as well as facility resources. Conclusions. The template can be used as a tool to ensure a consistent and comprehensive description of the radiotherapy section of clinical guidelines, care programmes and clinical trial protocols.

  • Residual mass in aggressive lymphoma : does size, measured by computed tomography, influence clinical outcome?
  • 2000
  • Ingår i: Acta Oncologica. - 0284-186X .- 1651-226X. ; 39:4, s. 485-489
  • Tidskriftsartikel (refereegranskat)abstract
    • Residual masses are frequently found in patients with aggressive lymphomas, following therapy. A study was undertaken to determine whether initial tumour size, changes during treatment, or size of the residual mass could provide prognostic information. Computed tomography (CT) examinations were carried out before, midway and after completion of chemotherapy in 37 patients with aggressive lymphoma with residual mass after treatment. The tumours were measured for both the greatest diameter sizes and area. The size of the residual mass correlated with the tumour size at diagnosis. Neither a large tumour size before treatment nor a large residual mass after treatment correlated with an increase in rate of relapse. The initial tumour reduction (measured after completion of half of the planned chemotherapy) was less pronounced in relapsing patients compared to relapse-free patients. Using a cut-off level of 70% tumour reduction (measured after completion of half of the planned chemotherapy), 66% of patients with a tumour reduction of < 70% relapsed, compared with 22% (p < 0.05) in those with more marked tumour regression.

  • Malignant lymphomas in coeliac disease evidence of increased risks for lymphoma types other than enteropathy-type T cell lymphoma.
  • 2005
  • Ingår i: Gut. - 0017-5749. ; 54:1, s. 54-9
  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • Background: Numerous studies have reported on the association between coeliac disease and the otherwise uncommon enteropathy-type T cell lymphoma (ETTL). A systematic risk assessment of more prevalent lymphoma entities, such as B cell and non-intestinal lymphomas, in coeliac disease has not been performed. Aims: In light of the increasing number of patients diagnosed with coeliac disease and the unknown aetiology of malignant lymphomas, we aimed to estimate the distribution and risk of lymphoma subtypes in coeliac disease. Methods: We reviewed and reclassified 56 cases of incident malignant lymphomas occurring in a Swedish population based cohort of 11 650 patients hospitalised with coeliac disease. The observed numbers of lymphoma subtypes were compared with those expected in the Swedish population. Results: The majority (n = 32, 57%) of lymphomas in the cohort were not intestinal T cell lymphomas. Significantly increased risks were observed for B cell non-Hodgkin lymphoma (NHL) (standardised incidence ratio (SIR) 2.2 (95% confidence interval (CI) 1.2-3.6); 11 non-intestinal and five intestinal) and for lymphomas of non-intestinal origin (SIR 3.6 (95% CI 2.3-5.2), 11 B and 14 T cell). Furthermore, 44% of patients with B cell NHL had a history of other autoimmune/inflammatory diseases. The relative risks for T cell NHL (SIR 51 (95% CI 35-68); n = 37) and for primary gastrointestinal lymphomas (SIR 24 (95% CI 16 34); five B and 25 T cell) were markedly increased, as anticipated. Conclusion: Most lymphomas complicating coeliac disease are indeed related to the disease and are not of the ETTL-type. There was a remarkable aggregation of autoimmune/inflammatory disorders, female sex, coeliac disease, and B cell lymphoma.
