Abstract

Background: Angiosarcomas represent less than 2% of all adult soft tissue sarcomas. Prognostic factors and the role of (neo-) adjuvant treatments in the management of localised angiosarcomas require further investigation. Methods: We have conducted a retrospective multicenter study (June 1980 to October 2009) of 107 patients with localised angiosarcomas. All of the cases were centrally reviewed by a certified pathologist. Univariate and multivariate analyses were conducted to identify independent poor prognostic factors (PF). Overall survival (OS) and Local Recurrence-Free Survival (LRFS) were estimated using the Kaplan-Meier method. The effect of treatments was explored using the Cox model after adjusting for the PF. Results: The median age was 71 years. 22.4% and 62.6% developed an angiosarcoma in pre-existing lymphoedema and within irradiated tissue respectively. The median OS, LRFS and Disease Recurrence-Free Survival (DRFS) were 38.8, 27 and 36.1 months, respectively. In multivariate analysis, the following parameters influenced the OS: lymphoedema (Hazard ratio (HR) = 2.0) and size >5 cm (HR = 1.5). After adjustment to these PF, RO margins was the only treatment parameter that improving the OS (HR = 0.2). In the multivariate analysis, the LRFS was influenced by an age >70 (HR = 1.8) and pre-existing lymphoedema (HR = 2.0). After adjustment for these PF, RO margins (HR = 0.5) and adjuvant radiotherapy (HR = 0.3) improved the LRFS. Conclusions: Our results suggest the following points: (i) pre-existing lymphoedema, tumour size and age >70 are probably the major prognostic factors in patients with localised angiosarcomas ; (ii) the achievement of RO margins is probably of major importance for improving the patient outcome and (iii) adjuvant radiotherapy probably decreased the risk of local recurrence.

<div type="abstract" xml:lang="en">Background: Angiosarcomas represent less than 2% of all adult soft tissue sarcomas. Prognostic factors and the role of (neo-) adjuvant treatments in the management of localised angiosarcomas require further investigation. Methods: We have conducted a retrospective multicenter study (June 1980 to October 2009) of 107 patients with localised angiosarcomas. All of the cases were centrally reviewed by a certified pathologist. Univariate and multivariate analyses were conducted to identify independent poor prognostic factors (PF). Overall survival (OS) and Local Recurrence-Free Survival (LRFS) were estimated using the Kaplan-Meier method. The effect of treatments was explored using the Cox model after adjusting for the PF. Results: The median age was 71 years. 22.4% and 62.6% developed an angiosarcoma in pre-existing lymphoedema and within irradiated tissue respectively. The median OS, LRFS and Disease Recurrence-Free Survival (DRFS) were 38.8, 27 and 36.1 months, respectively. In multivariate analysis, the following parameters influenced the OS: lymphoedema (Hazard ratio (HR) = 2.0) and size >5 cm (HR = 1.5). After adjustment to these PF, RO margins was the only treatment parameter that improving the OS (HR = 0.2). In the multivariate analysis, the LRFS was influenced by an age >70 (HR = 1.8) and pre-existing lymphoedema (HR = 2.0). After adjustment for these PF, RO margins (HR = 0.5) and adjuvant radiotherapy (HR = 0.3) improved the LRFS. Conclusions: Our results suggest the following points: (i) pre-existing lymphoedema, tumour size and age >70 are probably the major prognostic factors in patients with localised angiosarcomas ; (ii) the achievement of RO margins is probably of major importance for improving the patient outcome and (iii) adjuvant radiotherapy probably decreased the risk of local recurrence.</div>
