Objective: The majority of giant cell tumors of bone (GCTB) occur in adult patients, especially between the ages of 20 and 40. This study aims to investigate the imaging features of GCTBs in pediatric patients and compare their characteristics with adult cases.
Methods: Fifty-seven cases of patients aged 18 years old or younger were retrospectively analyzed, accounting for 12.
Background: Osteosarcoma is a tumour of malignant origin in children and adolescents. Recent progression indicates that it is necessary to develop new therapies to improve the patient's prognosis rather than strengthen anti-tumour chemotherapy. Researchers recently realised that cancer is a kind of disease with a metabolic disorder, and metabolic reprogramming is becoming a new cancer hallmark.

We report a case of a farmer who presented with synovial osteochondromatosis of his right knee that mimicked a huge hardball. A synovial proliferative disease associated with metaplasia of cartilage resulting in sporadic multiple intra-articular and extra-articular loose bodies. Our focus is to report a rare case successfully operated which has an educational significance in clinical practice.

We used the lasso Cox regression model to construct and verify the signature consisting of 14 immune-related gene pairs. This signature can accurately predict the overall survival of osteosarcoma patients and is an independent prognostic factor for osteosarcoma patients.

Yet, the prognostic value of these hematological markers in soft tissue sarcoma (STS) remains inconclusive. Thus, the aim of this meta-analysis was to check the effect of hematological markers on the prognosis of STS.

Method: A retrospective analysis was carried out on 68 cases of benign lesions in the proximal femur at our hospital from April 2002 to April 2013 (38 men and 30 women). Mean age at surgery was 35.
Objective: To explore the clinical efficacy and complications of treating sternal tumors by resection and titanium mesh thoracic reconstruction.
Methods: This retrospective analysis of eight patients with sternal tumors treated in the Department of Orthopedic Surgery at the First Affiliated Hospital of Zhengzhou University from January 2008 to June 2012 included five men and three women aged 37-66 years (mean, 50.4 years).
Ewing's sarcoma is the second most frequent primary malignant bone tumor, mainly affecting children and young adults. The notorious metastatic capability of this tumor aggravates patient mortality and remains a problem to be overcome. We investigated the effect of arsenic trioxide (As₂O₃) on the metastasis capability of Ewing's sarcoma cells.

The regulatory mechanisms for the rapid proliferation of chondrosarcoma cells and the particular aggressiveness of this sarcoma remain poorly understood. In this study, we investigate the effect of epigallocatechin-3-gallate (EGCG) on growth and apoptosis of chondrosarcoma cells.
