Methods: PubMed, Embase, and Web of Science electronic databases were searched from
their inception to March 2018. Studies reporting data on the relationship between tumor …

Abstract Background Objectives The impact of tumor necrosis as a prognostic factor in
gastrointestinal stromal tumor (GISTs) is still debated. The objective was to determine …

Tumor necrosis is associated with poor clinical outcomes in many malignancies. We aimed
to determine whether tumor necrosis was an independent predictor of outcomes in gastric …

Risk factors of gastrointestinal stromal tumors (GISTs) include tumor size, location, mitosis,
and tumor rupture. Although the first three are commonly recognized as independent …

Background Gastrointestinal stromal tumor (GIST) is known for its wide variability in
biological behaviors and it is difficult to predict its malignant potential. The aim of this study is …

Objective To evaluate the prognostic significance of various clinicopathologic parameters in
gastrointestinal stromal tumor (GIST), and to study the frequency of c-kit exon 11 mutations …

Gastrointestinal stromal tumors (GISTs) are potentially malignancies that can occur
anywhere in the digestive tract. Tyrosine kinase inhibitors (TKIs) such as imatinib have …

Background and objectives Whether gastrointestinal (GI) bleeding indicates gastrointestinal
stromal tumor (GIST) rupture and impacts prognosis is unclear. We examined the prognostic …

Objectives To assess computed tomography (CT) findings to assist in the distinction of low-
and high-grade gastrointestinal stromal tumors (GISTs) and to estimate their relative risk …

Purpose: Gastrointestinal stromal tumor (GIST) is a relatively rare tumor that is treated with
targeted therapies in advanced stages. Randomized clinical trials (RCT) often require long …
