Peutz-Jeghers syndrome (PJS) is a rare autosomal dominant disorder characterized by mucocutaneous hyperpigmentation, gastrointestinal (GI) hamartmatous polyps, and an increased risk of various malignancies. Pathogenic variants in the LKB1 tumor suppressor gene (also known as STK11) are the major cause of PJS. In this study, compound heterozygous variants of LKB1, c.890G > A/ c.1062C > G and del(exon1)/ c.1062C > G, were identified in two sporadic Chinese PJS cases respectively. Although all these three variants had been related to the autosomal dominant PJS in previous studies, all evidences collected in this study including de novo data, segregation data, population data, in-silico data, and functional data indicated that del(exon1) and c...

Gastrointestinal (GI) tumors are a leading cause of cancer-related deaths in the world. In fact, gastric cancer (GC) is the third cause of cancer deaths, whereas aesophageal neoplasm is the eighth most common cancer worldwide and its incidence, especially adenocarcinoma type, is continuously increasing. Also Hepatocellular carcinoma, Cholangiocarcinoma and pancreatic cancer represent a very interesting model to multidisciplinary approach and recently new drugs are used in their treatment. Currently, new clinical trials are designed including classic chemotherapy in association with either small molecule inhibitors (i...

Individuals with colorectal cancer (CRC) have a tendency to intestinal bleeding which may result in mild to severe iron deficiency anemia, but for many colon cancer patients hematological abnormalities are subtle. The fecal occult blood test (FOBT) is used as a pre-screening test whereby those with a positive FOBT are referred to colonscopy. We sought to determine if information contained in the complete blood count (CBC) report coud be processed automatically and used to predict the presence of occult colorectal cancer (CRC) in the setting of a large health services plan...

: 43 Background: Palliative chemotherapy and radiation are often used in patients with advanced stage of cancer. To weigh the risks and the benefits of this treatment, patients need to be adequately informed about all treatment aspects including the side effects and potential benefits. Unfortunately, many patients are not well informed about the goal of their treatment, and many are under the impression that this treatment can be curative. METHODS: This is a prospective survey based study that enrolled 46 patients with stage IV disease of all solid malignancies, who are being treated with palliative intent at the Edwards Comprehensive Cancer Center...

: 41 Background: SAR may be an alternative when hospice is declined. However, the outcomes of discharges to SAR in cancer patients with progressive (chemotherapy-refractory) disease are not known. We examined the characteristics and outcomes of patients with debility from progressive metastatic GI cancer who were discharged to SAR after an admission to our center. METHODS: An institutional electronic database was queried to identify patients of the GI medical oncology service of Memorial Sloan Kettering Cancer Center who had been discharged to a SAR facility...

: 85 Background: End-of-life care (EOLC) discussions for pts with advanced malignancies are often delayed resulting in unwanted, wasteful treatment. COTA Inc has developed a 7-item PRO instrument (LWC) to facilitate identification of pts in distress. A pilot study of 433 pts at a single institution was able to determine a threshold distress score (> 28) correlating with physician assessment of appropriateness for EOLC consultation (2015 ASCO Palliative Care Symposium). METHODS: LWC explores 4 personhood and clinical domains (performance status, pain, burden, and depression)...

: 51 Background: Overutilization of emergency room services by oncology patients is a known problem associated with increased admission rates and health care expenditure. A review of our oncology patients' emergency room (ER) visits from January to May 2015 demonstrated that 48% of ER visits happened during office hours. Consequently a rapid cycle quality improvement project was developed with an aim to decrease ER visits by 30% by September 2015. METHODS: A multidisciplinary team completed an action plan, starting with a project charter and definition of aim statement...

BACKGROUND AND AIM: Subepithelial lesions (SEL) are found in about 1% of all esophagogastroduodenoscopy (EGD) procedures, and GI stromal tumors (GISTs) are a type of SEL commonly encountered. Although the majority of SELs are benign, GISTs have malignant potential, making a definitive diagnosis important. Currently, the criterion standard for the diagnosis of GISTs is EUS-directed fine-needle aspiration (EUS-FNA). The definitive diagnosis of GISTs relies upon immunohistochemical (IHC) staining, which depends on enough tissue being submitted to the pathologist...

Radiation therapy is an integral component in the multimodality management of many gastrointestinal (GI) cancers at all stages of clinical presentation. With recent advances in technology and radiation delivery, external beam radiation therapy (EBRT) can be delivered with reduced toxicity. However, despite these advances, EBRT doses are still limited by the presence of radiosensitive serial structures near clinical targets in the GI tract. Relative to EBRT techniques, brachytherapy techniques have a lower integral dose and more rapid fall-off, allowing for high-dose delivery with little normal tissue exposure...

BACKGROUND: Evidence for the association between posttraumatic stress disorder (PTSD) and gastrointestinal (GI) disorders is mixed, owing in part to methodologic differences across studies. Further, studies which have combined GI disorders or symptoms for examination as one overall category may potentially obscure associations between PTSD and individual GI diagnoses. METHODS: This nationwide cohort study examined the incidence of all major non-malignant GI disorders in patients with a prior PTSD diagnosis (n = 4,076), compared to the general population incidence from 1995-2013, using Danish medical registry data...

MicroRNA (miR) can exert various biological functions by targeting oncogenes or tumor suppressor genes in numerous human malignancies. Recent evidence has shown that miR-148a increases the drug sensitivity of various cancer cells. Herein, we show that ectopic expression of miR-148a induces apoptosis, reduces clonogenicity, and increases the sensitivity to TRAIL and cisplatin in renal cancer cells. The luciferase reporter assay showed that miR-148a negatively regulated ras-related protein 14 (Rab14) expression by binding to the miR-148a binding site in the 3' untranslated region (3'UTR) of Rab14...

Gastrointestinal (GI) cancer is characterized by its aggressiveness and tendency to metastasize at early stage. Epithelial-mesenchymal transition (EMT), commonly known as the preparing step of metastasis, may account for the aggressive phenotype of GI cancer cells. The process of EMT is finely orchestrated by multiple layers of regulators. Signal transducer and activator of transcription 3 (STAT3) is a transcription factor constitutively activated in diverse malignancies. Recent studies have suggested an involvement of STAT3 in GI cancer EMT...

BACKGROUND: Spleen-preserving distal pancreatectomy with resection of the splenic vessels (VR-SPDP) is an effective procedure. However, hemodynamic changes in splenogastric circulation may lead to the development of gastric varices (GV) with a risk of gastrointestinal (GI) bleeding. This retrospective study aimed to assess the long-term postoperative clinical follow-up of patients and review the late postoperative abdominal computed tomography (CT) or endoscopic examination. METHODS: From 1988 to 2015, 48 consecutive VR-SPDP for benign or low-grade malignant disease were included...

Galectin decorates the cell membrane and forms an extracellular molecular association with galactoside units. Here, galactoside probes have been used to study galectin expression in neuroblastoma cells. The hypothesis behind this investigation has been that the molecular mechanisms by which glycans modulate neural metastatic cells involve a protein-carbohydrate association, galectin-galactose. Preliminary screening to validate the hypothesis has been performed with galactose moieties anchored to beads. The molecular association has been studied by FACS...

Craniopharyngiomas exhibiting histologic malignancy are extremely rare. Herein, we report the case of a 26-year-old male patient who underwent suprasellar mass excision via an interhemispheric transcallosal approach. Histopathological examination indicated that the craniopharyngioma was of the adamantinomatous subtype. The patient received postoperative medical treatment for endocrine dysfunction and diabetes mellitus without radiation treatment. Two years after the operation, he presented with progressive visual disturbance and altered mentality...

Gastric cancer (GC) is one of the most frequent epithelial malignancies worldwide. The gastrointestinal (GI) peptide gastrin is an important regulator of the secretion and release of gastric acid from stomach parietal cells and it also plays a vital role in the development and progression of gastric cancer. The aim of the current study was to investigate the role and underlying mechanism of gastrin and autophagy in regulating gastric cancer tumorigenesis. Gastrin-17 amide (G-17) was applied in the gastric cancer cell lines SGC7901 and MGC-803...

In patients with advanced breast cancer, most new calcifications detected on a mammogram after neoadjuvant chemotherapy are benign dystrophic calcifications, but this is not always observed. We present a patient with advanced breast cancer who had paradoxically increased malignant microcalcifications concomitant with primary tumor regression after undergoing neoadjuvant chemotherapy. After the neoadjuvant chemotherapy, the follow-up mammogram revealed that local, fine pleomorphic microcalcifications had markedly increased...
