Sorafenib is a molecular-targeted therapy used in palliative treatment of advanced hepatocellular carcinoma (HCC) in Child-Pugh A patients. We describe the case of a patient who presented with a large HCC in the left liver associated with portal vein thrombosis (PVT). After 9 months of sorafenib treatment, reassessment showed that the tumors had decreased in size with recanalization of the portal vein. A lateral left hepatectomy was performed and pathology showed complete necrosis of the tumor. Sorafenib can downstage HCC in patients with cirrhosis allowing further surgical resection.
Self-expandable plastic stents are currently recommended for refractory benign esophageal strictures but they show disappointing results in terms of migration and long-term efficacy. We report here our experience in the management of benign esophageal strictures with partially covered (PCSEMS) and fully covered self-expandable metal stents (FCSEMS). We performed a retrospective analysis of self-expandable metal stent (SEMS) placements for benign esophageal strictures from 1998 to 2011 in Rouen University Hospital. Twenty-two patients (15 men, 7 women) attempted 40 esophageal SEMS placements (17 PCSEMS, 23 FCSEMS) during this period. All technical complications were migrations. Migration was noted after 3/17 PCSEMS (17.6%) and 4/23 FCSEMS placement (17.4%, P = ns). Clinical complications occurred after 6/17 PCSEMS and 2/23 FCSEMS placements (35.3% vs. 8.7%, P = 0.053). PCSEMS caused two major complications (fistulae) whereas FCSEMS did not cause any major complication (11.7% vs. 0%). Mean dysphagia score was significantly lower after SEMS placement (1.68 vs. 3.08, P < 0.001) with similar results for PCSEMS and FCSEMS. Stent placement resulted in long-term clinical success for 23.5% of PCSEMS and 34.7% of FCSEMS (P = 0.0505). FCSEMS provide satisfying clinical success rate with an acceptable complication rate and they could constitute a relevant therapeutic option in the management of benign esophageal strictures.
157 Background: For pancreatic tumor, guidelines recommend pancreatic cytology examination by EUS-FNA as the first diagnostic procedure in unresectable patients. Detecting CTCs in blood could play the role of a “liquid biopsy”. The usefulness of CTC detection in the clinical management of these patients has not been established yet. Here, we aimed to prospectively evaluate the accuracy of a diagnostic method based on CTC detection. Methods: All patients referred from January 2011 to March 2012 for EUS-FNA procedure in a context of pancreatic solid tumor diagnosis were prospectively enrolled after their consent. Prior EUS-FNA procedure a sample of peripheral blood was collected. CTCs were analyzed using the ScreenCell method. Cells were considered as tumoral if they met these morphological criteria: nuclear diameter >14 µ, anisocytosis, anisocaryosis, nuclear membrane irregularities, large nucleolus, clots of tumoral cells with platelets and fibrin. All analysis was performed by a pathologist blinded to the EUS-FNA results. The diagnosis of pancreatic adenocarcinoma was defined either by pathological evidence based on FNA or surgical specimen, or by clinical outcome with metastatic evolution and CA19.9 serum level rather than 10 fold normal value. Results: A total of 40 patients were included. A pancreatic adenocarcinoma was confirmed in 27/40 patients (68.3%). In 21 of the 27 patients, pathological proof of adenocarcinoma was obtained by EUS-FNA. For the diagnosis of adenocarcinoma, sensitivity and specificity of EUS-FNA were 77.8% and 100% respectively. The diagnostic accuracy of FNA was 85%. CTC detection was positive in 15 patients. Sensitivity and specificity were 55.5% (CI95% [40.1%; 70.9%]) and 100% (CI95% [75%; 100%]) respectively. The diagnostic accuracy of CTC was 70%. Metastatic statuses, lymph node involvement, vascular invasion, size of tumor and CA19.9 serum level were not statistically associated with CTC detection. Conclusions: We suggest that CTC detection be applied as first-line procedure before EUS-FNA in the strategy of pancreatic tumor diagnosis. With the implementation of this blood test on a routine basis, approximately one half of these patients could avoid invasive EUS-FNA procedure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
