Suten(sunitinib)t is indicated for the treatment of gastrointestinal stromal tumor (GIST), a type of sarcoma, after disease progression on or intolerance to imatinib mesylate. Sutent is also indicated for the treatment of advanced renal cell carcinoma (RCC).
A Phase II clinical trial for sunitinib (S. George et al) in treating 53 patients with metastatic, locally advanced, or locally recurrent non-GIST sarcomas was presented in ASCO 2009. Sunitinib demonstrated notable evidence of metabolic response in several patients with non-GIST sarcoma. The relevance of disease control observed in subtypes with an indolent natural history is unknown, however, the durable disease control observed in DSRCT, solitary fibrous tumor, and giant cell tumor of bone suggests that future evaluation of sunitinib in these subtypes may be warranted. There are case reports for use in clear cell sarcoma patients.
