BACKGROUND AND OBJECTIVES: Total pelvic exenteration are performed in patients with locally advanced or recurrent pelvic malignances. Many patients have prolong hospital length of stay (LOS), but risk factors are not clearly identified. METHODS: From 2002 through 2012, 100 consecutive patients undergoing pelvic exenteration were retrospectively reviewed. A general linear model was used to examine risk factors for prolonged hospital LOS. RESULTS: Among the 100 patients, 51 had gastrointestinal cancer, 14 had genitourinary cancer, 31 had gynecologic cancer, and 4 had sarcoma...

Cowden syndrome (CS) represents one possible phenotype of the PTEN gene mutation, and it can cause hamartomas throughout the gastrointestinal tract, with a predisposition for malignancy. Fibroblastic polyps have not been associated with CS. A 45-year-old woman with CS presenting for colonoscopic surveillance was found to have multiple sessile polyps throughout the transverse, descending, and sigmoid colon, all 2-5 mm in diameter. Based on the morphologic features and the immunohistochemical profile, these lesions were classified as fibroblastic polyps...

BACKGROUND: Isolated myeloid sarcoma (MS) is a rare extramedullary tumor mass composed of malignant myeloid precursor cells without any evidence of leukemia in the peripheral blood and bone marrow. We describe the clinical characteristics and outcomes of patients diagnosed with isolated MS at our institution. METHODS: We retrospectively reviewed 9 of 497 acute myeloid leukemia (AML) patients (1.8%) with isolated MS. Isolated MS patients were divided into 2 groups according to the first-line treatment strategy: systemic treatment only (S) or local treatment with or without systemic treatment (LS)...

Colorectal cancer (CRC) is the most frequently diagnosed malignancy of the gastrointestinal tract. The dysregulation of microRNAs (miRNAs/miRs) has been reported in the majority of types of human cancer, and is correlated with tumorigenesis and tumor development. Abnormal expression of miR‑663 has been observed in various types of human cancer. However, little is known about its role in CRC. Therefore, the aim of the present study was to clarify the expression and potential role of miR‑663, and its underlying molecular mechanism in CRC...

BACKGROUND: There are few chemotherapeutic options for advanced gastric cancer with severe disseminated peritoneal metastases, which are usually accompanied by ascites. Bolus 5-fluorouracil (5-FU) plus leucovorin therapy has been widely used against gastrointestinal malignancies, with resulting mild toxicities. METHODS: We retrospectively analyzed the efficacy and safety of first-line chemotherapy with bolus 5-FU plus l-leucovorin in 30 advanced gastric cancer patients who had massive ascites and/or inadequate oral intake...

BACKGROUND: The majority of patients with gastrointestinal (GI) malignancies are older. Recently, it has become evident that elements from a geriatric assessment (GA) are powerful predictors of outcomes such as postoperative morbidity and mortality, length of stay, type of treatment received, and survival across several GI tumor types in older adults. A GA is a systematic evaluation of functional status, comorbidities, polypharmacy, cognition, nutritional status, emotional status, and social support...

INTRODUCTION: Elderly patients suffering from gastrointestinal malignancies are particularly prone to perioperative complications. Elderly patients often present with reduced physiological reserves, and comorbidities can limit treatment options and promote complications. Surgeons and anesthesiologists must be aware of strategies required to deal with this vulnerable subgroup. METHODS: We provide a brief review of current and emerging perioperative strategies for the treatment of elderly patients with gastrointestinal malignancies and frequent comorbidities...

BACKGROUND: The incidence of gastrointestinal cancer increases with age, with approximately 20% of these cases in people over 80 years of age. Due to pre-existing comorbidities, this onco-geriatric population often presents diagnostic and therapeutic challenges. METHODS: A systematic review of articles on PubMed was performed to determine the predictive ability of screening tools and their components regarding the occurrence of adverse outcomes in elderly onco-surgical patients with gastrointestinal malignancies...

Patients with advanced-stage pancreatic cancer are typically burdened by many symptoms that impair functioning and worsen quality of life. We report an exceptional case of a 73-year-old woman with T4N1M0 adenocarcinoma of the uncinate process of the pancreas who developed significant gastric outlet obstruction - an uncommon yet potentially life-threatening complication of disease progression. She developed progressive abdominal pain and emesis, and profound dilatation of her stomach was detected on a radiation therapy simulation CT scan that required urgent decompression...

Bile acids have been implicated in the development of gastrointestinal malignancies. Both the specific nature of individual bile acids and their concentration appear key factors in the carcinogenic potency of bile. Using liquid chromatography mass spectrometry (LC-MS) we performed quantitative profiling of bile extracted directly from the common bile duct in 30 patients (15 patients with pancreatic cancer and 15 patients with benign disease). Separation and detection of bile acids was performed using a 1.7μm particle size reversed-phase C18 LC column at a flow rate of 200μL/min with negative electrospray ionization MS...

The differential diagnosis for lymphadenopathy is wide and clinical presentations overlap, making obtaining an accurate diagnosis challenging. We sought to characterize the clinical and radiological characteristics, histological findings, and diagnoses for a cohort of patients with lymphadenopathy of unknown etiology. 121 Peruvian adults with lymphadenopathy underwent lymph node biopsy for microbiological and histopathological evaluation. Mean patient age was 41 years (Interquartile Range 26-52), 56% were males, and 39% were HIV positive...

INTRODUCTION: Gastric lipomas are unusual benign lesions and account for less than 1% of all tumours of the stomach and 5% of all gastrointestinal lipomas (Thompson et al.2003; Fernandez et al. 1983 [1,2]). Although predominantly asymptomatic and indolent; they may present with gastric outlet obstruction and upper gastrointestinal (GI) bleeding owing to size and ulceration. Only a few cases have been reported, presenting large in size with massive GI bleeding (Alcalde Escribano et al...

INTRODUCTION: Liposarcoma of the heart and stomach is rare. PRESENTAION OF CASE: We report a case of liposarcoma in both organs with dedifferentiated histology. A patient was referred to our hospital with anorexia and weight loss. Upper gastrointestinal tract endoscopy revealed 5-10-mm elevated lesions, and echocardiography and computed tomography showed tumorous lesions in the left atrium. Tumor resection and mitral valve replacement were performed, and biopsy was performed for the gastric tumor...

Individualized, goal-directed fluid therapy (GDFT) based on Doppler measurements of stroke volume has been proposed as a treatment strategy in terms of reducing complications, mortality and length of hospital stay in major bowel surgery. We studied the effect of Doppler guided GDFT on intestinal damage as compared with standard post-operative fluid replacement. STUDY DESIGN: Patients undergoing elective colorectal resection for malignancy were randomized to standard intra- and postoperative fluid therapy or standard fluid therapy with additional Doppler guided GDFT...

The gastrointestinal tract is an organized structure originating from the three embryonic germ layers: endoderm, mesoderm and ectoderm. Morphological changes that accompany its formation are relatively well known, although the underlying molecular mechanisms are still poorly defined. Intestinal metaplasia, resulting from an epithelial transdifferentiation process, is considered a precursor lesion of gastric adenocarcinoma, a malignancy with serious consequences in terms of morbidity and mortality worldwide...
