Undifferentiated intimal sarcoma mimicking a mycotic aneurysm.

Undifferentiated intimal sarcoma mimicking a mycotic aneurysm. Vasa. 2019 Sep 24;:1-4 Authors: Seo H, Hirai H, Aoyama T, Suehiro Y, Kubota Y, Suehiro S Abstract Intimal sarcoma of arteries is a rare malignant tumor, which often mimics other vascular disorders; therefore, preoperative diagnosis is often challenging. We herein report a 71-year-old man who presented with fever and elevated inflammatory markers who had a mass in the left internal iliac artery with rapid growth. Based on clinical findings, a diagnosis of mycotic aneurysm was made. We performed surgical intervention, including resection of the affected vessels with omentopexy, although intraoperative findings were not typical of a mycotic aneurysm. Microscopic and immunohistochemical examination demonstrated undifferentiated intimal sarcoma. The patient died of multiorgan failure two months after the surgery. The vascular surgeon should consider the possibility of a diagnosis of intimal sarcoma for patients with atypical findings and the importance of histological and immunohistochemical examination for precise diagnosis in surgical vascular cases.

In this study, we characterized the antigenic targets of KSHV-specific neutralizing antibodies (nAbs) in asymptomatic KSHV-infected individuals and KS patients with high nAbs titers. We quantified the extent to which various KSHV envelope glycoproteins (gB, ORF28, ORF68, gH, gL, gM, gN and gpK8.1) adsorbed/removed KSHV-specific nAbs from the plasma of infected individuals. Our study revealed that plasma from a majority of KSHV neutralizers recognizes multiple viral glycoproteins. Moreover, the breadth of nAbs responses against these viral glycoproteins varies among endemic KS, epidemic KS and asymptomatic KSHV-infected ind...

Conclusion: Despite promising preclinical rationale and tolerability of the combination therapy, no responses were observed, and the study did not meet parameters for further evaluation in MPNSTs. This trial was registered with (NCT02008877). PMID: 32089640 [PubMed]

Conclusion Both apatinib and anlotinib were effective for the treatment of sarcomas. However, the effectiveness of the two drugs and associated AEs varied based on the histological type of sarcoma. These differences may be due to their different sensitivities to targets such as RET, warranting further study.

Being the second most common type of primary bone malignancy in children and adolescents, Ewing Sarcoma (ES) encounters the dilemma of low survival rate with a lack of effective treatments. As an emerging approach to combat cancer, RNA therapeutics may expand the range of druggable targets. Since the genome-derived oncolytic microRNA-34a (miR-34a) is down-regulated in ES, restoration of miR-34a-5p expression or function represents a new therapeutic strategy which is, however, limited to the use of chemically-engineered miRNA mimics. Very recently we have developed a novel bioengineering technology using a stable non-coding...
