With discovery of KIT (CD117) mutations and the advent of KIT tyrosine kinase inhibitor imatinib, there has been substantial improvement in overall survival in patients with advanced and/or metastatic gastrointestinal tumors (GIST). Recently, sunitinib showed activity as second-line therapy in GIST patients after failure with imatinib. However, virtually all patients will eventually progress or become intolerable after imatinib and sunitinib. In preclinical models, sorafenib inhibits KIT activity and cell growth of imatinib-resistant tumors. The objective of this multi-center, non-randomized phase II study is to evaluate the safety and activity of sorafenib given as third-line therapy for GIST.
This is a non-randomized, open-label, multi-center, phase II study recruiting patients with advanced GIST who are pretreated with both imatinib and sunitinib. The current study will provide an estimate of the activity and safety of sorafenib in GIST. The primary study endpoint is the disease control rate (DCR), defined as complete or partial response or stable disease of at least 24 weeks of sorafenib therapy. Secondary endpoints include PFS, OS and safety.
Patients with advanced (unresectable and/or metastatic) GIST who failed after previous therapy involving both imatinib and sunitinib will be eligible. Failure to imatinib and sunitinib is defined as disease progression regardless of intervening response during therapy, or intolerance. There is no limit to the number of prior therapies a patient may have received (e.g., patients may have received therapy with nilotinib, other TKIs, or chemotherapy in addition to imatinib or sunitinib).

Sorafenib has shown efficacy in patients with imatinib-, sunitinib-, and regorafenib-resistant gastrointestinal stromal tumors (GISTs). No biomarker is currently available for predicting response to s...
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors involving the gastrointestinal tract. A small percentage of GISTs may cause acute gastrointestinal bleeding, which requir...

The main objective of the present study was to evaluate the significance of apoptosis in the Fletcher's risk classification for gastrointestinal stromal tumors (GISTs).
Gastrointestinal Stromal Tumors (GISTs) are a rare slow growing malignancy, accounting for less than 1% of all gastrointestinal (GI) tract tumors. These tumors are usually discovered incidentally by e...
Neoplasms of the endometrial stroma that sometimes involve the MYOMETRIUM. These tumors contain cells that may closely or remotely resemble the normal stromal cells. Endometrial stromal neoplasms are divided into three categories: (1) benign stromal nodules; (2) low-grade stromal sarcoma, or endolymphatic stromal myosis; and (3) malignant endometrial stromal sarcoma (SARCOMA, ENDOMETRIAL STROMAL).
All tumors in the GASTROINTESTINAL TRACT arising from mesenchymal cells (MESODERM) except those of smooth muscle cells (LEIOMYOMA) or Schwann cells (SCHWANNOMA).
Neoplasms derived from the primitive sex cord or gonadal stromal cells of the embryonic GONADS. They are classified by their presumed histogenesis and differentiation. From the sex cord, there are SERTOLI CELL TUMOR and GRANULOSA CELL TUMOR; from the gonadal stroma, LEYDIG CELL TUMOR and THECOMA. These tumors may be identified in either the OVARY or the TESTIS.
A tyrosine kinase inhibitor and ANTINEOPLASTIC AGENT that inhibits the BCR-ABL kinase created by chromosome rearrangements in CHRONIC MYELOID LEUKEMIA and ACUTE LYMPHOBLASTIC LEUKEMIA, as well as PDG-derived tyrosine kinases that are overexpressed in gastrointestinal stromal tumors.
Tumors or cancer of the GASTROINTESTINAL TRACT, from the MOUTH to the ANAL CANAL.
