Osseous invasion exhibited in soft-tissue sarcoma (STS) is recognized as a prognostic risk factor. Achieving a wide margin is the default surgical approach for local control. However, for STSs where the tumour is in contact with the adjacent cortex but without clear evidence of osseous invasion, such as medullary invasion, the question of whether bone resection can provide better local control or survival than more conservative sub-periosteal excision remains controversial. The aim of this study was to assess whether bone resection for thigh STS with cortical contact of the adjacent bone results in better local control and survival compared to sub-periosteal dissection, and to investigate the prognostic factors for clinical outcomes in STS. A retrospective cohort study was conducted on 142 patients with thigh STS exhibiting cortical contact but without medullary invasion, from May 2000 to May 2020. Patients underwent either composite bone resection or sub-periosteal excision. Demographics, clinical outcomes, and functional outcomes were compared between the two groups. Additionally, Cox regression analysis was used to analyze risk factors for local recurrence.Aims

Radiotherapy is a well-known local treatment for spinal metastases. However, in the presence of postoperative systemic therapy, the efficacy of radiotherapy on local control (LC) and overall survival (OS) in patients with spinal metastases remains unknown. This study aimed to evaluate the clinical outcomes of post-surgical radiotherapy for spinal metastatic non-small-cell lung cancer (NSCLC) patients, and to identify factors correlated with LC and OS. A retrospective, single-centre review was conducted of patients with spinal metastases from NSCLC who underwent surgery followed by systemic therapy at our institution from January 2018 to September 2022. Kaplan-Meier analysis and log-rank tests were used to compare the LC and OS between groups. Associated factors for LC and OS were assessed using Cox proportional hazards regression analysis.Aims
