TLDR
Tumor size predicts disease-specific survival in patients with primary disease who undergo complete gross resection and investigational protocols are indicated to reduce the rate of recurrence after resections and to improve the outcome for patients with GIST.Abstract:Â
ObjectiveTo analyze the outcome of 200 patients with gastrointestinal stromal tumor (GIST) who were treated at a single institution and followed up prospectively.Summary Background DataA GIST is a visceral sarcoma that arises from the gastrointestinal tract. Surgical resection is the mainstay of treread more

TL;DR: Imatinib induced a sustained objective response in more than half of patients with an advanced unresectable or metastatic gastrointestinal stromal tumor, indicating that inhibition of the KIT signal-transduction pathway is a promising treatment for advanced gastrointestinalStromal tumors, which resist conventional chemotherapy.

TL;DR: Key elements of the consensus are the defining role of KIT immunopositivity in diagnosis and a proposed scheme for estimating metastatic risk in these lesions, based on tumor size and mitotic count, recognizing that it is probably unwise to use the definitive term "benign" for any GIST, at least at the present time.

TL;DR: A randomised, double-blind, placebo-controlled, multicentre, international trial to assess tolerability and anticancer efficacy of sunitinib in patients with advanced gastrointestinal stromal tumour, noting significant clinical benefit, including disease control and superior survival.

TL;DR: Adjuvant imatinib therapy is safe and seems to improve recurrence-free survival compared with placebo after the resection of primary gastrointestinal stromal tumour.

TL;DR: Sequencing of c-kit complementary DNA from five GISTs revealed mutations in the region between the transmembrane and tyrosine kinase domains, suggesting that the mutations contribute to tumor development.

Gastrointestinal pacemaker cell tumor (GIPACT): gastrointestinal stromal tumors show phenotypic characteristics of the interstitial cells of Cajal.
TL;DR: It is concluded that gastrointestinal stromal tumors show striking morphological and immunophenotypic similarities with ICC and that they may originate from stem cells that differentiate toward a pacemaker cell phenotype and it is proposed that the noncommittal name "gastrointestinal stromic tumor" be replaced by gastrointestinal pacemaker Cell tumor.

Retroperitoneal soft-tissue sarcoma: analysis of 500 patients treated and followed at a single institution.
TL;DR: In this study of patients with retroperitoneal STS, stage at presentation, high histologic grade, unresectable primary tumor, and positive gross margin are strongly associated with the tumor mortality rate.

Gastrointestinal stromal tumors--value of CD34 antigen in their identification and separation from true leiomyomas and schwannomas
TL;DR: It is shown that gastrointestinal mesenchymal tumors can be immunophenotypically divided in categories that correlate with light microscopically defined diagnostic entities, namely typical leiomyomas, schwannomas, and GIST, most cases of the latter representing tumors of primitive meschymal cells that are CD34 positive.

Lymph node metastasis from soft tissue sarcoma in adults. Analysis of data from a prospective database of 1772 sarcoma patients.
TL;DR: It is concluded that lymph node metastases from sarcoma are rare in adults, but vigilance is warranted, especially in angiosarcoma, ERMS, and epithelioid subtypes, and radical lymphadenectomy is appropriate treatment for isolated metastasis to regional lymph nodes and may provide long-term survival.
