Abstract
Objective: To investigate the risk factors, clinical manifestations, and treatment outcomes in patients with Primary Bone Sarcomas (PBS).
Methods: This retrospective study included all patients with PBS treated between June 2016 and December 2023 at King Abdulaziz Medical City, excluding patients with incomplete data, presence of other malignancies, diagnosis at autopsy, or unknown metastasis. Data were analyzed using SPSS software version 27. A p-value of less than 0.05 was considered statistically significant. Log Rank test was used for survival analysis
Results: The study included 127 patients. Common past medical history included diabetes (7%), hypertension (5.5%), and metastasis at presentation (15%). Joint pain (76%) and bone swelling (75%) were common clinical presentations. The median overall survival was 5 years, with a 42% mortality rate. The presence of diabetes, hypertension, high Charlson score, high histological grading, and metastasis were more common among patients with osteosarcoma than other types (p < 0.05). Significant predictors of mortality included older age (HR: 1.03, p = 0.009), metastasis at presentation (HR: 8.19, p = 0.042), and metastasis (HR: 2.92, p = 0.010). Male gender (HR: 0.47, p = 0.020) had a lower risk of mortality.
Conclusion: This study highlights the significant burden of PBS in Saudi Arabia. Key risk factors such as age and metastasis at diagnosis significantly impact survival, underscoring the necessity for improved surveillance and follow-up strategies. Further research is needed to develop effective, risk-stratified treatment to improve outcomes for patients.
