The aim of the present study was to analyze the oncological and neurological outcome of patients undergoing interdisciplinary treatment for primary malignant bone and soft-tissue tumours of the spine within the last seven decades, and changes over time. We retrospectively analyzed our single-centre experience of prospectively collected data by querying our tumour registry (Medical University of Vienna). Therapeutic, pathological, and demographic variables were examined. Descriptive data are reported for the entire cohort. Kaplan-Meier analysis and multivariate Cox regression analysis were applied to evaluate survival rates and the influence of potential risk factors.Aims
Methods
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
Methods
Clinical studies of patients with bone sarcomas have been challenged
by insufficient numbers at individual centres to draw valid conclusions.
Our objective was to assess the feasibility of conducting a definitive
multi-centre randomised controlled trial (RCT) to determine whether
a five-day regimen of post-operative antibiotics, in comparison
to a
24-hour regimen, decreases surgical site infections in patients
undergoing endoprosthetic reconstruction for lower extremity primary
bone tumours. We performed a pilot international multi-centre RCT. We used
central randomisation to conceal treatment allocation and sham antibiotics
to blind participants, surgeons, and data collectors. We determined
feasibility by measuring patient enrolment, completeness of follow-up,
and protocol deviations for the antibiotic regimens. Objective
Methods
The most concerning infection of allografts and operative procedures
is methicillin resistant An iontophoresis cell was set up with varying concentrations
of Vancomycin within the medulla of a section of sheep tibia, sealed
from an external saline solution. The cell was run for varying times,
Vancomycin concentrations and voltages, to gain information on optimisation
of conditions for impregnating the graft. Each graft was then sectioned
and dust ground from the exposed surface. The dust was serially
washed to extract the Vancomycin and concentrations measured and
plotted for all variables tested.Objectives
