Anti-CXCR4 Antibody Combined With Activated and Expanded Natural Killer Cells for Sarcoma Immunotherapy

In this study, we propose a novel therapeutic approach based on anti-CXCR4 blocking antibody in combination with NKAE cell therapy to prevent rhabdomyosarcoma tumor implantation and lung metastasis. These results provide the first evidence for the efficacy of this combined immunotherapy for preventing sarcoma disease dissemination.

Discussion: A deep leaning network was trained to segment sarcomas on pediatric patients. Sarcomas are a very heterogenous class of tumors with large variations in size, shape and metabolism. This showed to be a challenging problem. Nevertheless, the network was able to accurately segment quite complex tumors (See figure, automatic segmentation in red outline) while in other cases it would fail. We attribute this to the limited number of training cases and hypothesize that an increasing number of training samples would improve the network.

This article discusses their clinical relevance, recent insights into their molecular biology, and the most important differential diagnoses. Regarding the latter, immunohistochemistry and (increasingly) molecular diagnostics play a role in the diagnostic workup. We conclude with a few considerations on intraoperative consultation and macroscopic examination, as well as pathologic staging and grading of uterine sarcomas as per the most recent American Joint Cancer Commission and the F édération Internationale de Gynécologie et d’Obstétrique staging systems.

Conclusions: The proposed nomogram is a reliable and robust tool for accurate prognostic prediction in patients with extremity soft tissue LMS. Introduction Soft tissue leiomyosarcoma (LMS) is an aggressive sarcoma, which originates from smooth muscle cells (1). Soft tissue LMS accounts for about 5–10% of all soft tissue sarcomas (2). It occurs in different sites, including the retroperitoneum, intraabdominal sites, and extremities (3). Extremity LMS comprised about 10–15% of extremity sarcomas, with a preference for the lower limb (4–6). Extremity LMS tends to have a better prognosis than uterine...

In conclusion, osmotic burst of inflated complement-damaged cells may occur, but these bursts are most likely a consequence of metabolic collapse of the cell rather than the cause of cell death. The Complement Cell Death Mediator: A Concerted Action of Toxic Moieties Membrane pores caused by complement were first visualized by electron microscopy on red blood cell membranes as large ring structures (22). Similar lesions were viewed on E. coli cell walls (23). Over the years, ample information on the fine ultrastructure of the MAC that can activate cell death has been gathered (24) and has been recently further examined (...

AbstractDICER1 syndrome is a rare tumor predisposition syndrome with manifestations that predominantly affect children and young adults. The syndrome is typically caused by heterozygous germline loss-of-functionDICER1 alterations accompanied on the other allele by somatic missense mutations occurring at one of a few mutation hotspots within the sequence encoding the RNase IIIb  domain.DICER1 encodes a member of the microRNA biogenesis machinery. The syndrome spectrum is highly pleiotropic and features a unique constellation of benign and malignant neoplastic and dysplastic lesions. Pleuropulmonary blastoma (PPB), the ...

AbstractProgresses in multimodal treatments have significantly improved the outcomes for childhood cancer. Nonetheless, for about one-third of patients with Ewing sarcoma, rhabdomyosarcoma, or osteosarcoma steady remission has remained intangible. Thus, new biomarkers to improve early diagnosis and the development of precision-targeted medicine remain imperative. Over the last decade, remarkable progress has been made in the basic understanding of miRNAs function and in interpreting the contribution of their dysregulation to cancer development and progression. On this basis, this review focuses on what has been learned abo...

We present the case of an adolescent male patient treated in our Department for a tumoral mass located in the middle third of the forearm. Magnetic resonance imaging (MRI) and angiography-computed tomography (angio-CT) showed a large mass located in the muscles of the anterior compartment of the forearm. Surgical treatment consisted of tumor ablation including segmental resection of the radial and ulnar arteries and of the median nerve, followed by saphenous autograft vascular bypass. The treatment plan was based on tumor type, histological grading (high), age, tumor size greater than 5 cm, unfavorable location, postoperat...
