SSG/AIO (SSG XVIII) Adjuvant study for high-risk GIST R A N D O M I Z E Arm 1 Imatinib Follow-up 12 months 48 months Imatinib Follow-up 36 months 24 months Arm 2 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. www.ssg-org.net

  15. SSGXX-a new adjuvant STS protocol 2007 “A Scandinavian Sarcoma Group (SSG) treatment protocol for adult patients with non-metastatic high-risk STS of the extremities and trunk wall”

  16. (Opened 1998-closed 31.12.05) • * 2 or 3 risk (SIN) factors • Size>8cm • Presence of necrosis • Presence of vascular invasion

  17. Introduction of a novel • risk factor assessment • Peripheral tumor growth pattern • Infiltrative growth of a STS is a • strong factor for both • local recurrence • and metastases

  18. Decision algoritm for adjuvant treatment in group A 2 or 3 risk-factors - Size >8 cm - Infiltrative growth - Necrosis No Not included in study No Vascular invasion Yes Yes Eligible in Group A

  19. Group ASSG XX Adjuvant therapy arm For high-risk STS in extremities and trunk wall with primary surgery Surgery Wide margin for subcutaneous tumors or radically amputated patients CT1 CT2 CT3 CT4 CT5 CT6 Max 12 weeks 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 weeks Surgery Marginal, for all tumors, wide margin for deep tumors RT 36 Gy CT1 CT2 CT3 (1.8 x 2/d x 10d) CT4 CT5 CT6 Max 12 weeks 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 weeks Surgery Intralesional margin, regardless of tumor depth RT 45Gy CT1 CT2 CT3 (1.8 x 2/d x 12.5d) CT4 CT5 CT6 Max 12 weeks 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 weeks CT regimen Doxorubicin: 60mg/m2 as 4 hours infusion Ifosfamide: 2g/m2 as a 2 hours infusion (with Mesna) on 3 consecutive days G-CSF routinely

  20. Group B SSG XX Preoperative therapy For high-risk STS in extremities and trunk wall when primary resection carriesan obvious risk of an intralesional margin RT MR Surgery CT1 CT2 (1.8 x 2/d x 10d) CT3 CT4 CT5 CT6 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 CT regimen Doxorubicin: 60 mg/m2 as 4 hours infusion Ifosfamide: 2g/m2 as a 2 hours infusion (with Mesna) on 3 consecutive days G-CSF routinely Surgery: 2.5 weeks after start of the third cycle. weeks
