Digital image analysis-based scoring system for endoscopic ultrasonography is useful in predicting gastrointestinal stromal tumors.

Gastric Cancer 2019 Feb 18. Epub 2019 Feb 18.

Department of Surgery, Pusan National University School of Medicine, Busan, South Korea.

Background: When gastric mesenchymal tumors (GMTs) measuring 2-5 cm in size are found, whether to undergo further treatment or not is controversial. Endoscopic ultrasonography (EUS) is useful for the evaluation of malignant potential of GMTs, but has limitations, such as subjective interpretation of EUS images. Therefore, we aimed to develop a scoring system based on the digital image analysis of EUS images to predict gastrointestinal stromal tumors (GISTs). Read More

PRE-OPERATIVE GASTRIC GIST DOWNSIZING: THE IMPORTANCE OF NEOADJUVANT THERAPY.

Arq Bras Cir Dig 2019 Feb 7;32(1):e1427. Epub 2019 Feb 7.

Hospital das Clínicas, Universidade Federal de Minas Gerais, Alfa Institute of Gastroenterology, Belo Horizonte, MG, Brazil.

Introduction: Gastric gastrointestinal tumors (GIST) are a rare and usually asymptomatic neoplasm that can present as abdominal mass in more advanced scenarios. Since surgical resection is the main aspect of the treatment, locally advanced tumors require multivisceral resection and, therefore, higher postoperative morbidity and mortality.

Objective: To perform a review the literature on the topic, with emphasis on the neoadjuvant therapy. Read More

Identification of imatinib-resistant long non-coding RNAs in gastrointestinal stromal tumors.

Oncol Lett 2019 Feb 11;17(2):2283-2295. Epub 2018 Dec 11.

Department of Radiotherapy and Medical Oncology, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, Zhejiang 325000, P.R. China.

Long non-coding RNAs (lncRNAs) are an abundant RNA species that belong to the competing endogenous RNA network, which serves a critical role in the development, diagnosis and progression of diseases. Using chip technology, the current study analyzed the expression of lncRNAs in paired normal gastric tissues, primary gastrointestinal stromal tumor (GIST) tissues and GIST tissues resistant to imatinib mesylate. Gene Ontology enrichment and Kyoto Encyclopedia of Genes and Genomes pathway analyses were used to predict potential tumorigenesis and drug resistance mechanisms. Read More

Department of Gastric Surgery, Fujian Medical University Union Hospital.

In gastrointestinal stromal tumors (GISTs), rupture is a high-risk feature; however, "tumor rupture" is inconsistently defined, and its prognostic value remains controversial.Six hundred ninety-one patients undergoing surgery for primary nonmetastatic GISTs from 2003 to 2015 at our institution were enrolled. The strict definitions of "tumor rupture" according to the Kinki GIST Study Group (KGSG) were used. Read More

A phase I study of ontuxizumab, a humanized monoclonal antibody targeting endosialin, in Japanese patients with solid tumors.

Invest New Drugs 2019 Jan 9. Epub 2019 Jan 9.

Eisai Co. Ltd., Tokyo, Japan.

Background We conducted a first-in-Japanese, phase I study of ontuxizumab, a humanized, anti-endosialin monoclonal antibody, to confirm its tolerability, safety, and pharmacokinetics, and identify exploratory efficacy. Methods This was a multicenter, multiple-dose, open-label study in Japanese patients aged ≥20 years with solid tumors, including gastric cancer (GC) or advanced hepatocellular carcinoma (HCC), who had failed standard chemotherapy. The study comprised two parts: part 1 (dose-escalation; ontuxizumab 2-12 mg/kg weekly) and part 2 (cohort-expansion; 4 or 8 mg/kg weekly, or 12 mg/kg biweekly). Read More

Gastrointestinal stromal tumors and synchronous intra-abdominal malignancies: Review of the literature.

J BUON 2018 Nov-Dec;23(6):1573-1579

Department of General Surgery, University Hospital of Larissa, Mezourlo, Larissa, Thessaly, 41110, Greece.

Purpose: Gastrointestinal stromal tumors (GISTs) are the most frequent neoplasms of mesenchymal origin affecting the gastrointestinal tract. GISTs quite frequently co-exist with other primary tumors in up to 33% of the cases. Such occurrence has been mainly described in the literature in the form of case reports and rarely of case series which hasn't been sufficient to prove if there is any association between these two entities.

Chinese consensus on management of tyrosine kinase inhibitor-associated side effects in gastrointestinal stromal tumors.

World J Gastroenterol 2018 Dec;24(46):5189-5202

Department of Gastrointestinal Surgery, Reiji Hospital, Shanghai Jiaotong University School of Medicine, Shanghai 200127, China.

Tyrosine kinase inhibitors (TKIs) have improved the overall survival of patients with gastrointestinal stromal tumors (GISTs), but their side effects can impact dose intensity and, consequently, the clinical benefit. To date, no guideline or consensus has been published on the TKI-associated adverse reactions. Therefore, the Chinese Society of Surgeons for Gastrointestinal Stromal Tumor of the Chinese Medical Doctor Association organized an expert panel discussion involving representatives from gastrointestinal surgery, medical oncology, cardiology, dermatology, nephrology, endocrinology, and ophthalmology to consider the systemic clinical symptoms, molecular and cellular mechanisms, and treatment recommendations of GISTs.

Imatinib‑induced apoptosis of gastric cancer cells is mediated by endoplasmic reticulum stress.

Oncol Rep 2019 Mar 19;41(3):1616-1626. Epub 2018 Dec 19.

Division of Oncology, Department of Internal Medicine, Korea University College of Medicine, Korea University Guro Hospital, Seoul 08308, Republic of Korea.

Imatinib is a powerful tyrosine kinase inhibitor that specifically targets BCR‑ABL, c‑KIT, and PDGFR kinases, and is used in the treatment of chronic myelogenous leukemia, gastrointestinal stromal tumors, and other types of cancers. However, the possible anticancer effects of imatinib in gastric cancer have not yet been explored. The present study evaluated the in vitro effects of imatinib on gastric cancer cells and determined the molecular mechanism underlying these effects. Read More

Imatinib and liver toxicity.

BMJ Case Rep 2018 Dec 7;11(1). Epub 2018 Dec 7.

Department of Gastroenterology, Glasgow Royal Infirmary, Glasgow, UK.

Imatinib is a specific tyrosine kinase inhibitor which has been approved for the treatment of Philadelphia chromosome-positive chronic myeloid leukaemia and c-KIT (CD117)-positive gastrointestinal stromal tumours. It has been associated with hepatotoxicity ranging from abnormal liver function tests to acute liver failure along with chronic hepatitis B reactivation. We report the case of a patient who was started on adjuvant treatment with imatinib following resection of a primary gastrointestinal stromal cell tumour of jejunum and developed severe hepatotoxicity.

Department of Thoracic Surgery, Beijing Friendship Hospital, Capital Medical University, Beijing, China.

Approximately 50% of patients with primary lung cancer have distant metastasis at the time of their first visit, but gastric metastasis is a rare occurrence. Herein, we report a case of progressive dysphagia as the first symptom and the final diagnosis of primary lung squamous cell carcinoma metastasis. A 61-year-old man was diagnosed with a solitary left lower lobe tumor and a solitary carcinoma of gastric cardia suspected to be metastatic or malignant stromal tumors. Read More
