  • Radixin, encoded by a gene on chromosome 11, plays important roles in cell motility, invasion and tumor progression. However, its function in pancreatic cancer remains elusive. In this study, radixin gene expression was suppressed with a lentivirus-mediated short-hairpin RNA (shRNA) method. We found that radixin shRNA caused down-regulation of radixin in PANC-1 cells, associated with inhibition of pancreatic cancer cell proliferation, survival, adhesion and invasive potential in vitro. When radixin-silenced cells were implanted in nude mice, tumor growth and microvessel density were significantly inhibited as compared to blank control cells or nonsense shRNA control cells. Thrombospondin-1 (TSP-1) and E-cadherin were up-regulated in radixin-silenced PANC-1 cells. Our results suggest that radixin might play a critical role in pancreatic cancer progression, possibly through invvolvement of down-regulation of TSP-1 and E-cadherin expression.

  • Purpose: We evaluate the role of transanal tube drainage (TD) as a conservative treatment for patients with anastomotic leakage (AL). Methods: Patients treated for AL who had undergone a low or an ultralow anterior resection with colorectal or coloanal anastomosis for the treatment of rectal cancer between January 2013 and January 2017 were enrolled in this study. The data were collected prospectively and analyzed retrospectively. The primary outcomes were the diagnosis and the management of AL. Results: Two hundred thirteen consecutive patients, 122 males and 91 females, were included. The mean age was $66.91{\pm}11.15years$, and the median body mass index was $24kg/m^2$ (range, $20-35kg/m^2$). The median tumor distance from the anal verge was 8 cm (range, 4-12 cm). Ninety-three patients (44%) received neoadjuvant therapy for nodal disease and/or locally advanced rectal cancer. Only 13 patients (6%) developed AL. Six patients developed subclinical AL as they had a defunctioning ileostomy at the time of the initial procedure. They were treated conservatively with TD under endoscopic guidance in the endoscopy unit and received intravenous antibiotics. Six weeks after discharge, these 6 patients underwent follow-up flexible sigmoidoscopy which showed a completely healed anastomotic defect with no residual stenosis. Seven patients developed a clinically significant AL and required reoperation with pelvic abscess drainage and Hartmann colostomy formation. Conclusion: These results suggest that TD for management of patients with AL is safe, cheap, and effective. Salvaging the anastomosis will help decrease the need for Hartmann colostomy formation. Proper patient selection is important.

  • Backgrounds/Aims: The role of inflammation in malignant cell proliferation has been well described. High values of platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) as markers of systemic inflammation have shown associations with unfavorable long-term outcomes. The purpose of this study was to determine values of NLR and PLR evaluated prior to and after surgery and their associations with mortality and recurrence rates of liver transplant patients with hepatocellular carcinoma (HCC). Methods: A total of 105 patients with HCC who underwent orthotopic liver transplantation (OLT) were retrospectively reviewed. NLR and PLR values were obtained from complete blood counts prior to and after surgery. Overall survival (OS) and recurrence-free survival (RFS) in relation with delta NLR and PLR were estimated. Results: Serum alpha-fetoprotein levels > 100 ng/mL (p = 0.014) and lymphovascular emboli in the specimen (p = 0.048) were identified to be significant predictors of RFS. Child-Pugh score (p = 0.016) was found to be an independent factor associated with poorer OS. An increasing delta PLR was associated with worse RFS, although it showed no significant association with OS. Conclusions: The analysis of PLR as a continuous variable may predict recurrence outcomes in patients undergoing OLT for HCC. It is more representative than isolated values.

  • Pancreatic and gastric fistulas are rare complications of emergency splenectomy, and it is extremely rare for a pancreatic fistula to be further complicated by a fistulation into the stomach. Here, we present a case of pancreatogastric fistula in a 60-year-old man who experienced polytrauma due to a blunt mechanism. He underwent emergency splenectomy for splenic injury and developed a pancreatic fistula as a complication. A percutaneous endoscopic procedure was performed to drain the fistula, after which he developed a pancreatogastric fistula as a further complication. A double-pigtail stent was inserted via gastroscopy into the fistula tract to allow internal drainage of the pancreatic collection into the stomach cavity. When a pancreatic fistula is complicated by gastric fistulation, endoscopic stenting of the pancreatogastric fistula tract for internal drainage is an effective treatment option.

  • We presented a case of posteriorly displaced fracture of the distal clavicle in Child. The closed reduction was failed due to posteriorly displaced proximal fragment and interpositon of trapezius muscle and periosteum. We found that periosteal sleeve and coracoclaviclar ligament and acromioclavicular ligament was intact. The open reduction should be considered for the treatment of the irreducible posteriorly displaced fracture of the distal clavicle in child.

  • Traumatic dislocation of the peroneal tendon is a rare injury. It should be distinguished from other conditions that can cause pain and disability of lateral aspect of the ankle joint. We experienced a case of chronic recurrent dislocation of the peroneal tendon, which was treated by deepening of the peroneal groove of the lateral malleolus and reattachment of the superior peroneal retinaculum. The clinical result was satisfactory.

  • Metaplastic breast cancer (MBC) is a rare type of breast carcinoma, characterized by various combinations of mesenchymal, adenocarcinoma and other epithelial components. MBC often manifests as a large mass, with low axillary lymph node involvement and poor prognosis. Knowledge and treatment patterns about MBC demographics, presentation and tumor characteristics are very limited. In clinical practice, MBC is usually treated based on the guidelines developed for infiltrating ductal carcinoma (IDC). The ideal treatment paradigm for MBC is unknown due to its low incidence and pathological variability, so potential predictors of treatment efficacy need to be explored. This review summarizes the current models and strategies for MBC according to the published literature.
