Osteosarcoma is one of the most common malignant bone tumors which affect adolescents. Neoadjuvant chemotherapy followed by operation has become recommended for osteosarcoma treatment. Whereas, the effects of conventional chemotherapy are unsatisfactory because of multidrug resistance, fast clearance rate, nontargeted delivery, side effects and so on. Accordingly, Nanoparticle-mediated targeted drug delivery system (NTDDS) is recommended to be a novel treatment strategy for osteosarcoma. NTDDS can overcome the above obstacles by enhanced permeability and retention effect and active targeting. The active targeting of the delivery system is mainly based on ligands. In this study, we investigate and summarize the most common ligands used in the latest NTDDS for osteosarcoma. It might provide new insights into nanomedicine for osteosarcoma treatment.

Metastatic renal osteosarcoma is a rare entity. We report a case of a 52-year-old male postright nephrectomy status presented to us with metastatic renal osteosarcoma. 18-fluorine- fluorodeoxyglucose (F-FDG) avid lesions were seen in the right renal bed with extension to adjacent hepatic parenchyma.

This case report is focused on a patient (a 32-year-old previously healthy man) with a femoral bone tissue tumor. The case underscores the diagnostic complexity of Telangiectatic Osteosarcoma (TOS) with Aneurysmal Bone Cystic (ABC) lesion and the importance of maintaining special immunohistochemical markers for differential diagnosis between low-grade osteosarcoma, primary ABC, and suspected TOS, which is a true mimicker of ABC. On the other hand, this presentation describes some molecular rearrangements seen in ABC.

Introduction: Time to initiation of therapy in oncological care is an influential factor in disease progression and survival outcomes in many cancer types. We aim to identify factors associated with delayed time to treatment (TTT) in high-grade osteosarcoma and its relationship to disease-specific survival (DSS).
Methods: The SEER database was queried for biopsy-confirmed cases of high-grade osteosarcoma between 2000 and 2021 using ICD-O-3 histology codes 9180/3-9194/3 and primary site codes C40.

Purpose: Teleangiectatic osteosarcoma is a histologic subtype of osteosarcoma that can mimic aneurysmal bone cysts and has so far been incompletely characterized.
Patients And Methods: We used the database of the Cooperative Osteosarcoma Study Group COSS (patient-registration 1980-2019) to better understand this rare histologic variant.
Results: 223 eligible patients were identified, 164 having reference pathology (median age 15.

The purpose of this study was to investigate potential therapeutic targets for osteosarcoma (OS) and offer hints regarding genetic factors for OS treatment using a bioinformatics method. This study processed 3 OS datasets from the gene expression omnibus database using R software, screening for differentially expressed genes (DEGs). After enrichment analysis, based on expression quantitative trait loci data and the genome-wide association study data of OS, Mendelian randomization analysis was used to screen the genes closely related to OS disease, which intersect with DEGs to obtain co-expressed genes, validation datasets were employed to verify the results.
