  7. SSG I Adjuvant chemotherapy in STS 1981 – 86 SSG V Treatment program for STS 1986 – SSG X Treatment of metastatic STS (VIG) 1991 – 97 SSG XII Metastasecetomy and CHT for lungmet. 1996 – 97 from STS. An EORTC/SSG randomized phase III study SSG XIII Treatment protocol for adults with 1998 – high-risk STS in extremities and trunk wall Soft Tissue Sarcoma www.ssg-org.net

  8. 1,0 ,9 ,8 ,7 ,6 ,5 ,4 ,3 ,2 ,1 1 2 3 4 5 High-risk STS (SSG XIII)doxorubicin/ifosfamide Overall survival 3 - year OS: 77% Years Promising preliminary results but: Biased patient selection Short follow-up time Overall vs metastases-free survival

  9. R A N D O M I Z E Imatinib Follow-up 12 months 48 months Imatinib Follow-up 36 months 24 months Arm 1 Arm 2 SSG XVIII Adjuvant study for high-risk GIST Primary objective: To investigate the recurrence-free survival in GIST patients with a high (>50%) risk of disease recurrence within the first 5 years following the diagnosis and treated with adjuvant imatinib mesylate either for 12 or 36 months.

  10. Osteosarcoma SSG II Combination therapy in OS 1982 – 1990 SSG VIII Therapy of OS 1990 – 1998 ISG/SSG I An Italian-Scandinavian treatment and 1997 – 2000 research protocol for high-grade osteosarcoma of the extremities ISG/SSG II Treatment of metastatic and pelvic 1998 – 2003 osteosarcoma SSG XIV A Scandinavian treatment research 2000 – 2004 protocol for extemity localized high- grade osteosarcoma Euroboss I A European treatment protocol for bone 2003 sarcoma in patients older than 40 years Euramos I An American/European treatment protocol 2004 for OS in patients <40 years www.ssg-org.net

  11. Euramos-1 A randomised trial of the European and American Osteosarcoma Study Group

  12. EURAMOS 1 • Euramos-1 • 4 y anticipated accrual time (1400 pts). Covers a population >0.5 billion people • Objectives • Event-free survival • Overall survival • Short-term toxicity • Long-term toxicity • Quality-of-life • Euramos-1 • Optimize the treatment of patients suffering from osteosarcoma. • Open for all patients with resectable high-grade osteosarcoma of the limbs or axial skeleton • The trial takes into account the strong prognostic value of tumor response to preoperative chemotherapy and divides patients accordingly

  13. Ewing´s sarcoma SSG IV Combined modality therapy in EWS 1984 – 90 SSG IX Therapy of EWS 1990 – 99 ISG/SSG III ISG/SSG treatment protocol for 1999 non-metastatic EWS ISG/SSG IV ISG/SSG treatment protocol for 1999 high-risk EWS www.ssg-org.net
