  • Radiation dose as a risk factor for malignant melanoma following childhood cancer

    • The aim of this study was to determine therapy-related risk factors for the development of melanoma after childhood cancer. Among 4401 3-year survivors of a childhood cancer in eight French and British centres and 25 120 patients younger than 20 years old at first malignant neoplasm (FMN) extracted from the Nordic Cancer Registries, 16 patients developed a melanoma as a second malignant neoplasm (SMN). A cohort study of the French and British cohorts was performed. In a nested case-control study, the 16 patients who developed a melanoma as a SMN (cases) were matched with 3-5 controls in their respective cohort according to gender, age at the first cancer, the calendar year of occurrence of the first cancer and follow-up. Radiotherapy appeared to increase the risk of melanoma for local doses > 15 Gy, Odds Ratio (OR)= 13 (95% Confidence Interval (CI): 0.94-174). Regarding chemotherapy, we observed an increased OR for both alkylating agents and spindle inhibitors, OR 2.7 (95% CI: 0.5-14). Children treated for a gonadal tumour as a FMN were found to be at a higher risk of melanoma, OR 8.7 (95% CI: 0.9-86). The adjusted OR for the local radiation dose was 1.07 (95% CI: 1.00-1.15). In conclusion, radiotherapy may contribute to an increased risk of melanoma as a SMN, but only at very high doses of low linear energy transfer radiation. Common genetic origins between gonadal tumours and malignant melanomas are likely. (C) 2003 Elsevier Ltd. All rights reserved.

  • Scandinavian Sarcoma Group Osteosarcoma Study SSG VIII: prognostic factors for outcome and the role of replacement salvage chemotherapy for poor histological responders
  • 2003
  • Ingår i: European Journal of Cancer. - : Elsevier. - 1879-0852. ; 39:4, s. 488-494
  • Tidskriftsartikel (refereegranskat)abstract
    • From 1990 to 1997, 113 eligible patients with classical osteosarcoma received neo-adjuvant chemotherapy consisting of high-dose methotrexate, cisplatin and doxorubicin. Good histological responders continued to receive the same therapy postoperatively, while poor responders received salvage therapy with an etoposide/ifosfamide combination. With a median follow-up of 83 months, the projected metastasis-free and overall survival rates at 5 years are 63 and 74%, respectively. Independent favourable prognostic factors for outcome were tumour volume < 190 ml, 24-h serum methotrexate > 4.5 muM and female gender. The etoposide/ifosfamide replacement combination did not improve outcome in the poor histological responders. In conclusion, this intensive multi-agent chemotherapy results in > 70% of patients with classical osteosarcoma surviving for 5 years. The data obtained from this non-randomised study do not support discontinuation and exchange of all drugs used preoperatively in histological poor responders. As observed in previous Scandinavian osteosarcoma studies, female gender appears to be a strong predictor of a favourable outcome. (C) 2003 Elsevier Science Ltd. All rights reserved.

  • Endothelial damage after treatment with low-molecular weight heparins - a morphological study
  • 2003
  • Ingår i: Scandinavian Cardiovascular Journal. - : Taylor & Francis. - 1651-2006. ; 37:1, s. 30-33
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective-Recent studies failed to show long-term benefit with low-molecular weight heparins (LMWH) in unstable coronary heart disease. A previous study of vascular effects of the cytostatic agent 5-fluorouracil (5-FU) showed that dalteparin prevented thrombosis induced by 5-FU but endothelial damage was not ameliorated and was present also in animals treated with dalteparin only. This study investigates the influence of LMWH currently in clinical use on arterial endothelium in vivo. Design-Eighty rabbits in four groups were treated with dalteparin, enoxaparin, tinzaparin and saline, respectively. Arterial endothelium was examined after 3, 14, 30 and 60 days with scanning electron microscopy. Results-All three groups treated with LMWH showed moderate damage to the endothelium, with contracted vessel wall and endothelial cells, cell membrane damage, denudation of subendothelium and adhering platelets. Contrarily, the control group exhibited a normal endothelium. Conclusion-Morphologic examination of arterial endothelium shows that all investigated LMWH exert a moderate toxic effect on endothelial cells. The clinical impact of these observations, e. g. concerning effect of long-term LMWH treatment, needs to be further elucidated.
