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.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
