A Prospective, Multicenter Study on Best Clinical Use of Imatinib in the Advanced Gastrointestinal Stromal Tumors
Open-label, multicenter study of imatinib (400mg/die p.o.)in patients with advanced gastrointestinal stromal tumors. Patients will be treated for up to 12 months. Data regarding its best clinical use in terms of tumor response, survival, tolerability and safety profile will be prospectively collected.
Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

The objective of this study is to compare the clinical outcomes following resumption of dosing (re-challenge) with Imatinib plus best supportive care versus placebo plus best supportive ca...
A phase IIIb study of patients with gastrointestinal stromal tumors who have had progressive disease while on 400 mg imatinib. Patients will be randomly assigned to either sunitinib 37.5 ...
RATIONALE: Imatinib mesylate and sunitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase I trial is studying the side effe...
The purpose of this study is to determine if escalating the dose of imatinib to keep the drug blood level at ≥ 1100 ng/ml leads to better outcomes for patients.
The study will investigate the comparative efficacy and safety of two oral inhibitors of Kit and PDGFR: nilotinib 400 mg bid, a novel agent, and imatinib 400 mg bid, an approved agent with...
To evaluate the impact of primary site, NIH risk and imatinib treatment on the prognosis of patients with gastrointestinal stromal tumors(GIST).
Gastrointestinal stromal tumors(GIST) are the most common mesenchymal tumors of the gastrointestinal tract. Most of these stromal tumors are characterized by mutations in the KTT or platelet-derived g...
Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors arising in the gastrointestinal tract. Over the last decade, the management and prognosis of GISTs has changed dramatically with mol...
ABSTRACT Gastrointestinal stromal tumors are rare malignancies characterized by c-kit and PDGFR-α mutations targeted by imatinib. Pleural effusion is a very rare side effect of imatinib treatment....
Constitutively activating mutations in the KIT and platelet-derived growth factor receptor α (PDGFRA) RTKs play a crucial role in the biology of gastrointestinal stromal tumors (GISTs), and this dise...
Medical and Biotech [MESH] Definitions
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.
Tumors or cancer of the GASTROINTESTINAL TRACT, from the MOUTH to the ANAL CANAL.
Mucocellular carcinoma of the ovary, usually metastatic from the gastrointestinal tract, characterized by areas of mucoid degeneration and the presence of signet-ring-like cells. It accounts for 30%-40% of metastatic cancers to the ovaries and possibly 1%-2% of all malignant ovarian tumors. The lesions may not be discovered until the primary disease is advanced, and most patients die of their disease within a year. In some cases, a primary tumor is not found.
