Neoadjuvant and Adjuvant Chemotherapy in High-risk Soft Tissue Sarcoma

Phase 2
Completed
Conditions
Soft Tissue Sarcoma
Interventions
Drug: EIA chemotherapy
Registration Number
NCT01382030
Lead Sponsor
Heidelberg University
Brief Summary

Neo- and adjuvant chemotherapy is used in high-risk soft tissue sarcoma to improve systemic control. Patients in this trial are treated with 4 cycles of chemotherapy (EIA, etoposide, ifosfamide, adriamycin) preoperatively, followed by local surgery and radiotherapy. An additional 4 cycles of adjuvant chemotherapy is administered. Treatment response is assessed by MRI and CT scans and FDG-PET in a subgroup of patients.

Detailed Description

The role of chemotherapy in high-risk soft tissue sarcoma is controversial. Though many patients undergo initial curative resection, distant metastasis is a frequent event resulting in 5-year overall survival rates of only 50 - 60%. Neo-adjuvant and adjuvant chemotherapy has been applied to achieve pre-operative cytoreduction, assess chemosensitivity and to eliminate occult metastasis. The current protocol comprises for cycles of neoadjuvant chemotherapy ((EIA, etoposide 125 mg/m2 iv days 1 and 4, ifosfamide 1500 mg/m2 iv days 1 - 4, doxorubicin 50 mg/m2 day 1, pegfilgrastim 6 mg sc day 5), local surgery and radiotherapy as well as further 4 cycles of adjuvant EIA. Treatment response is assessed by MRI and CT scans and FDG-PET in a subgroup of patients.

Primary Outcome Measures
NameTimeMethod
Disease-free survival2 years after study completion

Disease-free survival will be calculated from the time of definite surgery to radiologically proven local or distant failure or patient´s death due to sarcoma related cause.

Secondary Outcome Measures
NameTimeMethod
Radiologic Tumor ResponseEvery 6 weeks for an average of 8 months, then every 3 months for 2 years

Tumor response to therapy will be assessed by MRI and CT scans. Response will graded according to RECIST criteria.

Cardiac ToxicityEvery 6 weeks for an average of 8 months

Changes in cardiac ejection fraction will be assessed by echocardiograms. Toxicities will be graded according to CTCAE.

Overall Survival2 years after study completion

Overall survival will be calculated as the time interval from the date of therapy induction to patient's death or last follow up.

Grade of histological necrosisAfter definite surgery, approx. 12-15 weeks after study inclusion

Grade of histological necrosis in tumor specimen will be assessed after surgery and graded according to Salzer-Kuntschik.

Hematological toxicityOnce weekly for an average of 8 months

Hematological toxicity will be assessed by complete blood counts. Toxicity will be graded according to CTCAE.

Renal ToxicityOnce weekly for an average of 8 months

Renal toxicity will be assessed by changes from baseline creatinin levels. Toxicity will be graded according to CTCAE.

Liver ToxicityOnce weekly for an average of 8 months

Liver toxicity will be assessed by changes from baseline liver function tests, e.g. ASAT/ALAT. Toxicity will be graded according to CTCAE.

Correlation of Tumor Necrosis and Decline in PET SUVAfter tumor resection, approx. 12-15 weeks after study inclusion

Decline in PET SUV will be correlated with grade of histological necrosis in tumor specimen after surgery.
