Special Issue Information

Dear Colleagues,

Malignant bone and soft tissue tumors (sarcomas) are relatively common neoplasms. Some of them arise typically in pediatric patients. In general, low-grade tumors show a tendency for local recurrence and are often difficult to resect surgically depending on the location. In addition, low-grade sarcomas do not usually show a good response to neoadjuvant treatments. High-grade sarcomas are very aggressive and have a tendency for distant metastasis, and although they show a better response to cancer treatment, they usually develop treatment resistance over time, and overall survival is shorter. New therapeutic targets are needed that can potentially avoid the spread and progression of the disease. New insights into tumor biology, histopathology, immunophenotype and molecular alterations of bone/soft tissue tumor are needed in order to better understand the clinical outcome and to find potential therapeutic targets including immunotherapy.

The Special Issue, entitled "Molecular Research Targeting Sarcomas: Diagnosis and Therapeutics", aims to provide a research platform for the collection of the latest original and review articles covering immunohistochemical and molecular biological studies of factors related to the control of bone and soft tissue malignant tumors and action mechanisms of anti-sarcoma targets.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Intimal sarcomas (IS) are rare malignant mesenchymal tumors arising in large blood vessels of the systemic and pulmonary circulation and also in the heart. They are morphologically similar to other spindle cell, poorly differentiated sarcomas. The prognosis is poor and depends mainly on surgical options. Three cases of IS were collected from two institutions. Clinical data were retrieved and histological study was performed. A wide immunohistochemical panel was analyzed. FISH of MDM2 gene was performed, and a molecular study with NGS was implemented in all cases. The mean age of our cases was 54 years. Histologically, the tumors presented a diffuse growth pattern with heterogeneous atypical epithelioid or spindle cells and extensive thrombosed areas. All cases presented intense immunoexpression for MDM2, CDK4, CD117, c-myc, PDGFRA, and p16. PDGFRA, HTERT, and pan-TRK gained expression, while p16 lost intensity, being weaker in both the local recurrences and xenografts. The three cases showed amplification of MDM2 by FISH. NGS analysis revealed amplifications in the CDK4, PDGFRA, and KIT genes, together with BRAF mutation and KRAS amplification. P16 was expressed in all cases, losing intensity in local recurrence and xenografts. Two new alterations, a BRAF mutation and a KRAS amplification, were detected by NGS in different tumors, opening up new therapeutic options for these patients. Full article
