Retrospective analysis for thirty-nine patients with solitary fibrous tumor of pleura and review of the literature

BackgroundSolitary fibrous tumor of the pleura (SFTP) is an uncommon neoplasm arising from mesenchymal cells. The aim of this study is to summarize the experience and the outcome of the surgical treatment for 39 cases of SFTP.MethodsFrom January 2004 to December 2008, 39 patients underwent surgical resection of SFTP in our department. All patients had clinical follow-up by the same team of surgeons. The mean follow-up was 40.3 months.ResultsA local removal of the neoplasm was accomplished by video-assisted thoracic surgery (VATS) in 9 patients (group A) and by thoracotomy in 30 patients (group B) respectively. Comparing with group B, operations in group A took significantly less operative time, blood loss and spent less time in the intensive care unit and hospital. All specimens were positive for CD34 and Bcl-2. One patient developed recurrence, and the remaining 38 patients are alive and disease free at the end of follow-up.ConclusionsMalignant SFTP still had the potential recurrence. VATS represents the more acceptable choice for the selected patients with SFTP.

Transcriptome Network Analysis Reveals Potential Candidate Genes for Esophageal Squamous Cell Carcinoma

The esophageal squamous cell carcinoma (ESCC) is an aggressive tumor with a poor prognosis. Understanding molecular changes in ESCC should improve identification of risk factors with different molecular subtypes and provide potential targets for early detection and therapy. Our study aimed to obtain a molecular signature of ESCC through the regulation network based on differentially expressed genes (DEGs). We used the GSE23400 series to identify potential genes related to ESCC. Based on bioinformatics we constructed a regulation network. From the results, we could establish that many transcription factors and pathways closely related with ESCC were linked by our method. STAT1 also arose as a hub node in our transcriptome network, along with some transcription factors like CCNB1, TAP1, RARG and IFITM1 proven to be related with ESCC by previous studies. In conclusion, our regulation network provided information on important genes which might be useful in investigating the complex interacting mechanisms underlying the disease.

Thoracoscopic and laparoscopic radical esophagectomy with lateral-prone position

With 20 years of development, minimally-invasive treatment for esophageal cancer has been widely spread. However, surgeons have not reached consensus about the optimal minimally-invasive operation method, or whether the effect of radical lymph nodes dissection is comparable to the traditional open procedure. Thoracoscopic esophagectomy with lateral-prone position combines the advantages of both lateral position (allowing quick conversion to open procedure) and prone position (good visual area and complete lymphadenectomy). Together with laparoscopic abdominal lymphadenectomy, gastric tube formation and jejunostomy, this approach provides an easier way for minimally-invasive radical esophagectomy. In this article, approaches for thoracoscopic esophagectomy with lateral-prone position and total mediastinal lymphadenectomy, combined with totally laparoscopic gastric mobilization, abdominal lymphadenectomy, gastric tube formation and jejunostomy, will be presented by video instructions. All the procedures were under the rule of radical lymphadenectomy. Cervical lymph nodes dissection and esophago-gastrostomy were the same as those in open procedure, which will not be discussed here.
