Conditions
Keywords
refractory desmoplastic small round cell tumors, PDGF-R
Brief summary
An open-label, non-comparative study conducted to investigate the activity and safety of imatinib mesylate in refractory desmoplastic small round cell tumors expressing PDGF-R. Patients will be treated up to 12 months, or to disease progression. Tumor will be evaluated according to Recist criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Overall tumor response rates | Assessed every 3 months | An imaging technique (CT scan or MRI) determined tumor response according to RECIST criteria. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Explore how Imatinib cooperated with other treatment modatilities | Survival data was collected until death | Recorded survival after treatment and other associated treatment modalities. |
| Safety and tolerability | Safety data collected until patients were no longer in study | — |
| Conversion rate to surgical resectability | After best tumor response. | Assessed actual resectability rate after therapy compared to resectability before therapy. |
| Mutational analysis of molecular targets of imatinib (at any time during the study) | At any time during the study | — |
