Gastrointestinal stromal tumors (GIST) compose approximately 20% of soft tissue sarcomas with an annual incidence of approximately 7 per million population. GISTs occur throughout the GI tract, most commonly in the stomach or small intestine. The main treatment for localised GIST is surgical resection. At least 40% of these patients will develop recurrence or metastasis following complete resection. Local recurrence, liver metastases and/or dissemination within the abdominal cavity are the most common clinical manifestations. Although imatinib and sunitinib has greatly improved the quality of life and survival of patients with advanced GIST. Analysis of clinical trials revealed that patients with tumours with KIT exon 17 or 18 mutations, with a second mutation in KIT exon 17 or 18, had worse responses to imatinib and sunitinib. Some patients with PDGFRA D842V mutation do not respond to the present standard therapies.
Anlotinib (1-[[[4-(4-fluoro-2-methyl-1H-indol-5-yloxy)-6-methoxyquinolin-7-Yl] oxy] methyl]cyclopropanamine dihydrochloride) , a multi-targeted tyrosine kinase inhibitor (TKI), characterized as a highly selective and potent c-KIT, VEGFR, PDGFR, FGFR inhibitor. In vitro and in vivo, Anlotinib has a broad spectrum of inhibitory action on tumor angiogenesis and growth, which showed broad activity against soft tissue sarcoma and GIST with D842V, D816H, V560G and V654A mutations. In 2015, the US FDA granted orphan drug treatment for ovarian cancer.

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.
