In order to find out the potential indicators predicting prognosis of malignant gastrointestinal stromal tumors (GISTs) after surgical resection, we collected clinical records of 80 patients with malignant GISTs. Tumor location, size, mitotic index, necrosis were compared with the prognosis of malignant GISTs by Kaplan-Meier method and log-rank test. After a median follow-up of 844 days (52–2 145), we found that as National Institutes of Health suggested, tumors with intermediate risk had more favorable prognosis than that with high risk. Their 3-year survival rate were 65.3% and 41.3%, respectively (P<0.001). Moreover, tumor size and mitotic index were associated with free survival. The 3-year survival rate for patients with tumor size≤10 cm and>10 cm were 62.3% and 41.8%, respectively (P = 0.002), Tumors with mitotic index≤5/50 HPF had a higher 3-year survival rate than tumors with mitotic index>5/50 HPF (67.1% versus 40.7%, P = 0.005). The presence of necrosis was directly related to the malignant behavior. The 3-year survival rate for presence and absence necrosis were 50.8% and 64.8% (P = 0.008). From the present study, we can conclude that besides tumors size and mitotic index, tumor location and necrosis also influence on the long-term survival of patient with malignant GISTs after surgical resection.

Hemoperitoneum is a rare and potentially life-threatening complication of GIST. We reported a 54-year-old man who developed disseminated intra-abdominal recurrence from a previously resected gastrointestinal stromal tumour (GIST) of the small bowel, and the patient presented with hemoperitoneum. Emergent debulking surgery was performed. A high dose imatinib was prescribed. Despite the presence of residual disease, the patient was well clinically 8 months after the operation. Even though, there is no evidence to support the routine use of debulking surgery in the management of GIST. In our patient, disease progression after second line targeted therapy and the absence of alternative treatment options for spontaneous rupture and hemoperitoneum prompted us to treat the patient aggressively. Resection of the ruptured GIST was carried out for control of bleeding and to prevent recurrent bleeding in this patient with good surgical risks. During the treatment decision-making, the patient’s general condition, the risk of surgery and the extent of dissemination were taken into consideration. In this patient who presented with spontaneous rupture of a small intestinal GIST, the novel use of targeted therapy and aggressive surgical treatment produced reasonably good survival outcome.

This study was performed to evaluate the oncological and reproductive outcomes of childbearing-age women treated with fertility-sparing surgery (FSS) for non-epithelial ovarian tumors in China. One hundred and forty eight non-epithelial ovarian tumor women treated with FSS between January 1, 2000 and August 31, 2015 from two medical centers in China were identified. Progression-free survival (PFS) was 88.5%, whereas overall survival (OS) was 93.9%. Univariate analysis suggested that delivery after treatment is related to PFS (P=0.023), whereas histology significantly influenced OS. Cox regression analysis suggested that only histology was associated with PFS and OS (P<0.05). Among the 129 women who completed adjuvant chemotherapy (ACT), none developed amenorrhea. Among the 44 women who desired pregnancy, 35 (79.5%) successfully had 51 gestations including 35 live births without birth defects. Non-epithelial ovarian tumors can achieve fulfilling prognosis after FSS and chemotherapy. Histology might be the only independent prognostic factor for PFS and OS. FSS followed by ACT appeared to have little or no effect on fertility. Meanwhile, postoperative pregnancy did not increase the PFS or OS. Use of gonadotropin-releasing hormone agonist was not beneficial for fertility.

To date, gastric carcinoma (GC) is one of the common and fatal digestive malignancies worldwide. The prognosis of GC is not always satisfactory because of late diagnosis. Scholars are keen on discovering novel accurate and economical biomarkers in body liquids for GC screening to detect and evaluate the lesion before the results of imaging techniques are obtained. While traditional serum assays have limited sensitivity and specificity, gastrointestinal juice may provide relevant specific biomarkers because of its close contact with the tumor. Herein, the current progress in the relationship between gastrointestinal fluid analyses and GC is systematically and comprehensively reviewed. The detection of gastric juice pH, fluorescence spectrum, cytology, Helicobacter pylori-associated markers, nitrosamines, conventional tumor markers, amino acids, proteomics, microRNAs, long noncoding RNAs, protein-coding genes, vitamin C, etc., and combination tests of different category markers could provide important diagnostic and prognostic clues for gastrointestinal diseases. Particularly, early GC may be efficiently screened using gastric juice. Gastrointestinal fluid examination could also predict the adverse effects of postgastrectomy, such as pancreatic leakage, fistula, and abscess. Gastric fluid markers should be further studied to reveal the early predicators of malignancy and complications. The methods for obtaining the samples of gastrointestinal juice with minimum incision should also be comprehensively investigated.

Strategies in comprehensive therapy for gastrointestinal (GI) cancer have been optimized in the last decades to improve patients’ outcomes. However, treatment options remain limited for late-stage or refractory diseases. The efficacy of immune checkpoint inhibitors (ICIs) for treatment of refractory GI cancer has been confirmed by randomized clinical trials. In 2017, pembrolizumab was approved by the US Food and Drug Administration as the first agent for treatment of metastatic solid tumors with mismatch repair deficiency, especially for colorectal cancer. Given the different mechanisms, oncologists have focused on determining whether ICIs-based combination strategies could achieve higher efficacy than conventional therapy alone in late-stage or even front-line treatment of GI cancer. This review discusses the current status of combining immune checkpoint inhibitors with molecular targeted therapy, chemotherapy, or radiotherapy in GI cancer in terms of mechanisms, safety, and efficacy to provide basis for future research.

Swallowing multiple magnets is not uncommon worldwide and it frequently leads to serious consequences. However, most patients fail to receive timely and correct diagnosis and treatment. A literature search was performed to establish an algorithm for these accidents by the authors to identify relevant articles published from June 1987 to October 2010 in Google, Medline, ISI Web of Knowledge Ovid, CNKI, Korea Med and library document delivery, using search terms “magnet ingestion, ” “fistula, ” and “perforation. ” A total of 149 patients with ingestion of magnetic foreign bodies from 20 countries and areas were identified. 22 of them were companioned with neurological and psychiatric disorders. Swallowing magnets occurred throughout childhood and adolescent, mostly ranging 2 to 4 years in age. Various gastrointestinal damages such as necrosis and intestinal perforation or fistula were encountered. Damage from swallowing multiple magnets carries a significant risk of morbidity and even mortality throughout childhood to adolescent worldwide. Older children and adults with neurological and psychiatric problems may be at high risk for such accidents. Early intervention is crucial.

Wireless capsule endoscopy has become a common procedure for diagnostic inspection of gastrointestinal tract. This method offers a less-invasive alternative to traditional endoscopy by eliminating uncomfortable procedures of the traditional endoscopy. Moreover, it provides the opportunity for exploring inaccessible areas of the small intestine. Current capsule endoscopes, however, move by peristalsis and are not capable of detailed and on-demand inspection of desired locations. Here, we propose and develop two wireless endoscopes with maneuverable vision systems to enhance diagnosis of gastrointestinal disorders. The vision systems in these capsules are equipped with mechanical actuators to adjust the position of the camera. This may help to cover larger areas of the digestive tract and investigate desired locations. The preliminary experimental results showed that the developed platform could successfully communicate with the external control unit via human body and adjust the position of camera to limited degrees.
