- 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.

- Effects of solar EUV on positive ions and heavy negative charge carriers (molecular ions, aerosol, and/or dust) in Titan’s ionosphere are studied over the course of almost 12 years, including 78 flybys below 1400 km altitude between TA (October 2004) and T120 (June 2016). The Radio and Plasma Wave Science/Langmuir Probe-measured ion charge densities (normalized by the solar zenith angle) show statistically significant variations with respect to the solar EUV flux. Dayside charge densities increase by a factor of ≈2 from solar minimum to maximum, while nightside charge densities are found to anticorrelate with the EUV flux and decrease by a factor of ≈3–4. The overall EUV dependence of the ion charge densities suggest inapplicability of the idealized Chapman theory below 1200 km in Titan’s ionosphere. Nightside charge densities are also found to vary along Titan’s orbit, with higher values in the sunward magnetosphere of Saturn compared to the magnetotail.

- PURPOSE: To what extent active surveillance and deferred treatment for localized risk prostate cancer are used is unclear. We assessed the use of surveillance and of deferred treatment in a population based, nationwide cohort in Sweden.MATERIALS AND METHODS: In the National Prostate Cancer Register of Sweden, with a 98% coverage vs the compulsory Swedish Cancer Registry, we identified 8,304 incident cases of prostate cancer in 1997 to 2002 with age younger than 70 years, clinical local stage T1 or 2, N0 or Nx, M0 or Mx and serum prostate specific antigen less than 20 ng/ml. Data were extracted from medical charts for 7,782 of these men (94%) at a median of 4 years after diagnosis.RESULTS: Primary treatment was surveillance for 2,065 men (26%), radical prostatectomy for 3,722 (48%), radiotherapy for 1,632 (21%) and hormonal treatment for 363 (5%). Men on surveillance had lower local tumor stage, grade and prostate specific antigen, and were older than those who received active primary treatment (p <0.001). After a median surveillance of 4 years 711 men (34%) on surveillance had received deferred treatment, which was radical prostatectomy for 279 (39%), radiotherapy for 212 (30%) and hormonal treatment for 220 (30%).CONCLUSIONS: Surveillance was a common treatment for patients younger than 70 years with localized prostate cancer in Sweden in 1997 to 2002, 26% of men with localized prostate cancer started surveillance and after a median followup of 4 years, 66% of these men remained on surveillance.

- OBJECTIVES: To provide a descriptive review of the establishment of the National Prostate Cancer Register (NPCR) in Sweden, to present clinical characteristics at diagnosis and to calculate the relative survival of different risk groups after 5 years. MATERIAL AND METHODS: Since 1998, data on all newly diagnosed prostate cancers, including TNM classification, grade of malignancy, prostate-specific antigen (PSA) level and treatment, have been prospectively collected. For the 35,223 patients diagnosed between 1998 and 2002, relative survival in different risk groups has been calculated. RESULTS: Between 1998 and 2002, 96% of all prostate cancer cases diagnosed in Sweden were registered in the NPCR. The number of new cases increased from 6137 in 1998 to 7385 in 2002. The age-standardized rate rose in those aged < 70 years, while it was stable, or possibly declining from 1999, in the older age groups. The proportion of T1c tumours increased from 14% to 28% of all recorded cases. The age-adjusted incidence of advanced tumours (M1 or PSA > 100 ng/ml) decreased by 17%. The proportion of patients receiving curative treatment doubled. Patients with N1 or M1 disease or poorly differentiated tumours (G3 or Gleason score 8-10) had a markedly reduced relative 5-year survival rate. CONCLUSIONS: It is possible to establish a nationwide prostate cancer register including basic data for assessment of the disease in the whole of Sweden. The introduction of PSA screening has increased the detection of early prostate cancer in younger men and, to a lesser extent, decreased the incidence of advanced disease. The effect of these changes on mortality is obscure but the NPCR in Sweden will serve as an important tool in such evaluation.

- Background: Studies on adolescents and young adults with acute lymphoblastic leukemia suggest better results when using pediatric protocols for adult patients, while corresponding data for acute myeloid leukemia (AML) are limited. Procedure: We investigated disease characteristics and outcome for de novo AML patients 10-30 years old treated in pediatric or adult departments. We included 166 patients 10-18 years of age with AML treated according to the pediatric NOPHO-protocols (1993-2009) compared with 253 patients aged 15-30 years treated in hematology departments (1996-2009) in the Nordic countries. Results: The incidence of AML was 4.9/million/year for the age group 10-14 years, 6.5 for 15-18 years, and 6.9 for 19-30 years. Acute promyelocytic leukemia (APL) was more frequent in adults and in females of all ages. Pediatric patients with APL had similar overall survival as pediatric patients without APL. Overall survival at 5 years was 60% (52-68%) for pediatric patients compared to 65% (58-70%) for adult patients. Cytogenetics and presenting white blood cell count were the only independent prognostic factors for overall survival. Age was not an independent prognostic factor. Conclusions: No difference was found in outcome for AML patients age 10-30 years treated according to pediatric as compared to adult protocols.

Tidskriftsartikel (refereegranskat)abstract
- Objective This study aimed to explore the attitudes, practices and work-related experiences among Swedish physicians regarding the referral process, integration and transition between oncology care and palliative care (PC). Methods A cross-sectional online survey was performed with a study-specific questionnaire in 2016-2017 in south-eastern Sweden. Physicians working with cancer patients within surgical specialties, medical specialties and paediatric oncology participated. Results The vast majority of the 130 participating physicians (99.2%) stated that PC was beneficial for the patient and were positive about early integration of PC (65.5%). Still, only 27.6% of the participants introduced PC at an early stage of non-curable disease. However, paediatric oncologists had a very early introduction of PC in comparison with medical specialties (p = 0.004). Almost 90% of the study population said they wanted to know that the patient had been taken care of by another care facility. Conclusions Despite the physicians' positive attitude towards early integration and referral to PC, they often acted late in the disease trajectory. This late approach can reduce the patient's opportunity of improving quality of life during severe circumstances. There is a need for in-depth knowledge of the physicians' challenges in order to bridge the gap between intentions and actions.

- and purpose: To investigate incidence and location of locoregional recurrence (LRR) in patients who have received postoperative locoregional radiotherapy (LRRT) for primary breast cancer. LRR-position in relation to applied radiotherapy and the primary tumours biological subtype were analysed with the aim to evaluate current target guidelines and RT techniques in relation to tumour biology.Medical records were reviewed for all patients who received postoperative LRRT for primary BC in southwestern Sweden from 2004-2008 (N=923). Patients with LRR as a first event were identified (N=57, distant failure and death were considered competing risks). CT images identifying LRR were used to compare LRR locations to postoperative LRRT fields. LRR risk and distribution were then related to the primary BC biological subtype and to current target guidelines.Cumulative LRR incidence after 10 years was 7.1% (95%CI 5.5-9.1). Fifty-seven of the 923 patients in the cohort developed LRR (30 local recurrences (LR), 30 regional recurrences (RR), of which 3 cases of simultaneous LR/RR). Most cases of LRR developed fully (56%) or partially (26%) within postoperatively irradiated areas. The most common location for out-of-field RR was cranial to RT fields in the supraclavicular fossa. Patients with an ER- (HR 4.6, p<0.001, 95%CI 2.5-8.4) or HER2+ (HR 2.4, p=0.007, 95%CI 1.3-4.7) primary BC presented higher risks of LRR compared to those with ER+ tumours. ER-/HER2+ tumours more frequently recurred in-field (68%) rather than marginal/out-of-field (32%). In addition, 75% of in-field recurrences derived from an ER-/HER+ tumour, compared to 45% of marginal/out-of-field recurrences. A complete pathological response in the axilla after neoadjuvant treatment was associated with a lower degree of LRR risk (p=0.022).Incidence and locations of LRR seems to be related to the primary BC biological subtype. Individualized LRRT according to tumour biology may be applied to improve outcomes.
