Surgery and proton beam therapy for mediastinal extraskeletal osteosarcoma

We present the case of a 73-year-old man with a hoarseness. Imaging studies revealed a large calcified tumor of the median mediastinum. Surgery was performed, but complete resection was impossible and about two-thirds of the tumor was excised. The tumor was pathologically diagnosed as ESOS. Proton beam therapy has been performed on the remaining lesion, and the patient is alive without tumor regrowth for 29 months. This is the first case of mediastinum ESOS successfully treated with surgery and postoperative proton therapy.

(National University of Science and Technology MISIS) Scientific team of a small innovative enterprise Biomimetix, based on the National University of Science and Technology MISIS together with their colleagues from the N.N. Blokhin National Medical Research Centre of oncology developed a unique implant to replace the damaged bone fragment. The implant, which imitates real bone structure, was installed to a domestic cat with osteosarcoma by surgeons of the veterinary clinic 'Biocontrol'.

Authors: Song MZ, Zhang FL, Lin LJ Abstract As one of the leading causes of cancer-associated mortalities worldwide, the overall survival rate of osteosarcoma has stably remained at 15-30% for several decades. (3R)- 5,6,7-trihydroxy-3-isopropyl-3-methylisochroman-1-one (TIM), isolated from the whole plant of Selaginella moellendorffii Hieron., has been reported to have pharmacological activities. In the present study, the anti-proliferative effects of TIM against osteosarcoma were evaluated, and the underlying molecular mechanisms were explored. The results demonstrated that TIM inhibited proliferation and induced ...

(The Translational Genomics Research Institute) A bone cancer known as osteosarcoma is genetically similar in dogs and human children, according to the results of a study published today by Tufts University and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope. The findings could help break the logjam in the treatment of this deadly disease, which hasn't seen a significant medical breakthrough in nearly three decades.

Abstract Bone is a passive storage organ for zinc, which contains about 30% of the total body zinc. However, during extreme zinc deficiency, only a small fraction of zinc is released in contrast to other tissues where zinc is released like monocytes or conserved, e.g., skeletal muscle. Zinc plays an important role in bone tissue remodeling. Zinc homeostasis is regulated by several zinc transporters (ZnTs) and importers (ZIPs), but their expression dynamics concerning zinc status of bone cells is not well understood. The study aimed to elucidate the effects of zinc supplementation and depletion on the transcript le...

In conclusion, the outcomes of our research verified that p300 could directly acetylate JHDM1A at K409 site, which reduces the demethylation of H3K36me2, enhanced the transcription of p21 and puma, and thereby inhibited the growth and metastasis of osteosarcoma. PMID: 31307234 [PubMed - in process]
