Sarcomas account for only 1% of adult solid tumours. Visceral sarcomas except Gastrointestinal Stromal Tumours (GIST) are rare and therefore little is known about the natural history and prognosis of these tumours. They tend to occur in older adults with no sex predilection and are characterized by an aggressive behaviour. Proper evaluation of these tumours is necessary because these are uncommon tumours which often present with advanced disease in an anatomically complex location. Since there are very few published studies on visceral sarcomas, the data is insufficient to suggest prognosis and optimum treatment strategies...

Only a few studies have revealed using laparoscopic technique with limited resection of gastrointestinal stromal tumour (GIST) of the duodenum. A 68-year-old man was admitted to the hospital due to upper gastrointestinal (GI) bleeding. Evaluation revealed an ulcerated, bleeding GI tumour in the second part of the duodenum. After control of bleeding during gastroduodenoscopy, he underwent a laparoscopic wedge resection of the area. During 1.5 years of follow-up, the patient is disease free, eats drinks well, and has regained weight...

BACKGROUND: Imatinib mesylate (IM) is the preferred treatment for the majority of patients with metastatic gastrointestinal stromal tumour (GIST). Low trough IM concentration (Cmin) values have been associated with poor clinical outcomes in GIST patients. However, there are few studies of repeated measurements of IM levels, and therapeutic drug monitoring is not yet a part of routine clinical practice. This study was conducted to reveal clinical scenarios where plasma concentration measurement of IM trough level (Cmin) is advantageous...

The Delta-like 1 homolog (DLK1) gene is a paternal imprinting gene located on human chromosome 14q32, a site associated with frequent chromosomal mutations in GIST. The expression level of DLK1 is closely associated with the outcome of tumours. However, no study has reported the DLK1 expression in GIST. Here, we demonstrated that DLK1 showed low expression in GIST patients with low risk according to the modified National Institute of Health (NIH) criteria. With increasing tumour risk level, DLK1 gene and protein expression levels gradually increased...

The present case report described the acute presentation, diagnosis and management of a primary gastrointestinal stromal tumour (GIST) of the ileum. A male patient (age, 51 years) was admitted to Maggiore Hospital (Parma, Italy) due to presenting with fever, dysuria and lower abdominal pain. Ultrasonography and computed tomography showed a 7,5×5,5-cm pelvic mass containing air and purulent fluid indicative of an intraperitoneal abscess. The patient was subjected to diagnostic laparoscopy, which revealed a huge, soft cystic mass arising from the small bowel...

Healthy tissues surrounding abdomino-pelvic tumours can be impaired by radiotherapy, leading to chronic gastrointestinal complications with substantial mortality. Adipose-derived Mesenchymal Stromal Cells (Ad-MSCs) represent a promising strategy to reduce intestinal lesions. However, systemic administration of Ad-MSCs results in low cell engraftment within the injured tissue. Biomaterials, able to encapsulate and withstand Ad-MSCs, can overcome these limitations. A silanized hydroxypropylmethyl cellulose (Si-HPMC) hydrogel has been designed and characterized for injectable cell delivery using the operative catheter of a colonoscope...

BACKGROUND: The gastrointestinal stromal tumours (GIST) are the most common soft tissue sarcomas of the digestive tract. They are usually found in the stomach (60-70%) and small intestine (25-30%) and, less commonly, in the oesophagus, mesentery, colon, or rectum. The symptoms present at diagnosis are, gastrointestinal bleeding, abdominal pain, abdominal mass, or intestinal obstruction. The type of symptomatology will depend on the location and size of the tumour. The definitive diagnosis is histopathological, with 95% of the tumours being positive for CD117...

We report a case of an 8-year-old boy who underwent an ultrasound for investigation of a left upper quadrant mass and who was subsequently diagnosed with gastrointestinal stromal tumour of his stomach. Abdominal ultrasound showed a large cystic mass in the left upper abdomen which was further characterised by magnetic resonance imaging. At laparotomy, a large cystic lesion was excised from his stomach, which was confirmed at histology to be a gastrointestinal stromal tumour. We briefly discuss the presentation and imaging findings of paediatric gastrointestinal stromal tumour and how it differs from the adult form of the disease and treatments...

INTRODUCTION: Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal neoplasms (85%) of the gastrointestinal (GI) tract; duodenal GISTs constitute 3-5% of all GISTs and represent 10-30% of all malignant tumours of the duodenum. Rarely, patients present severe bowel obstruction, perforation or severe bleeding. The radical resection with complete removal of the tumour remains the main therapeutic approach. We performed a local resection in patients with suspected GIST admitted for emergency treatment for GI bleeding...

Sarcomas constitute a rare group of malignancies. According to histology, different treatment options are effective. For gastrointestinal stromal tumours (GISTs), targeted treatment with imatinib controls about 20% of advanced or metastatic disease, whereas chemotherapy is more effective for the rest of the sarcomas. Currently, new targeted treatments are emerging, showing activity in cases resistant to established primary treatment. On the other hand, the exciting results of immunotherapy for other solid tumours, for example, melanoma and lung cancer, make it a promising option in the fight against sarcomas...

Tyrosine-kinase inhibitors (TKIs) represent the only hopes for long-term survival for patients with chronic myeloid leukaemia (CML) and gastrointestinal stromal tumours. Thus, uninterrupted use of TKIs is of importance in such patients. Pure red cell aplasia (PRCA) is a rare disorder, not previously known to be associated with TKIs. We present, to the best of our knowledge, the first case of a patient with CML who developed PRCA secondary to both imatinib and nilotinib. Although PRCA was controlled on withdrawal of TKI, TKI continuation in the patient with CML is important...

Dedifferentiated liposarcoma is a liposarcoma that contains a well-differentiated liposarcoma component juxtaposed to areas of high-grade non-lipogenic sarcoma and was believed to occur from well-differentiated liposarcoma after several years. Dedifferentiated liposarcoma most commonly occurs in the retroperitoneum, while an intraperitoneal location is extremely rare, only seven cases have been reported in literature. Many pathologists recognize that a large number of intra-abdominal poorly differentiated sarcomas are dedifferentiated liposarcomas...
