- Prognostic scores support clinicians in selecting risk-adjusted treatments and in comparatively assessing different results. For patients with chronic-phase chronic myeloid leukemia (CML), four baseline prognostic scores are commonly used. Our aim was to compare the prognostic performance of the scores and to arrive at an evidence-based score recommendation. In 2949 patients not involved in any score development, higher hazard ratios and concordance indices in any comparison demonstrated the best discrimination of long-term survival with the ELTS score. In a second step, of 5154 patients analyzed to investigate risk group classification differences, 23% (n = 1197) were allocated to high-risk by the Sokal score. Of the 1197 Sokal high-risk patients, 56% were non-high-risk according to the ELTS score and had a significantly more favorable long-term survival prognosis than the 526 high-risk patients according to both scores. The Sokal score identified too many patients as high-risk and relatively few (40%) as low-risk (versus 60% with the ELTS score). Inappropriate risk classification jeopardizes optimal treatment selection. The ELTS score outperformed the Sokal score, the Euro, and the EUTOS score regarding risk group discrimination. The recent recommendation of the European LeukemiaNet for preferred use of the ELTS score was supported with significant statistical evidence.

- Estonia regained independence in 1991 after five decades of occupation by the Soviet Union. The present population-based survey was carried out over five consecutive 5-year study periods (1982-2006) on the incidence and survival of de novo acute leukemia patients aged ≥65years at diagnosis in Estonia and in a well-defined area in western Sweden. During the study period of retrospective work (1982-1996), the first 10years were carried out while Estonia was still under the mentorship of the Soviet Union. Over these years, Estonian hematologists did not have access to therapeutic measures readily available to Swedish hematologists, and the results for survival for western Swedish patients with acute myeloid leukemia (AML) far exceeded those of their Estonian counterparts. However, the results for acute lymphoblastic leukemia were equally dismal in the two countries. Subsequent prospective population-based studies were carried out during the years 1997-2006. A gradual improvement as to long-term relative survival of the Estonian AML patients was observed. When studying 2002-2006, no difference as regards relative survival at 5years was anymore present between the two countries. Over the first 20years of our population-based studies, it was repeatedly observed that the age-standardized incidence rate particularly for de novo AML was considerably higher for the western Swedish as compared to the Estonian cohorts. During the last 5-year study period (2002-2006), no such difference between the two countries was present, indicating that some true changes in the reporting procedure in Estonia had occurred.

- Background: In a recent retrospective study, we investigated the incidence and survival of de novo acute leukemia (AL) patients aged 16-64 years over three 5-year periods (1982-1996) in Estonia and in the Western Swedish Health Care Region. The incidence rates were similar in the two countries, but the survival data were highly different. Thus, relative survival at 5 years for de novo AL patients in Estonia was virtually negligible, whereas the corresponding figures for the Swedish patients increased from 20.3 to 38.9% during the study period. Aim: To prospectively compare the results for incidence and outcome of de novo AL between the two countries during 1997-2001. Results: Incidence rates for de novo AL were lower in Estonia than in western Sweden but not significantly so. However, the survival for de novo AL patients in Estonia had improved considerably, with the relative survival at 5 years being 16.4%; such improvement was particularly seen in acute myeloid leukemia patients. For the Swedish patients, no change in survival was recorded. Conclusion: In Estonia, a remarkable improvement in outcome for young de novo AL patients was seen after 1996. Nevertheless, relative survival for the Estonian patients had still not reached the levels found in the Swedish cohort.
