Summary
This study identified key factors influencing jaw cancer survival. Smoking history and advanced age significantly increase the risk of poor prognosis in patients with primary jaw malignancies.
Area of Science:
- Oncology
- Oral and Maxillofacial Surgery
- Cancer Research
Background:
- Primary jaw malignancies are rare but aggressive tumors.
- Understanding their characteristics and prognostic factors is crucial for effective management.
Purpose of the Study:
- To investigate the epidemiological characteristics of primary jaw malignancies.
- To identify significant prognostic factors for disease-free and overall survival.
Main Methods:
- Retrospective review of 80 patients diagnosed with malignant jaw tumors between 2006 and 2016.
- Statistical analysis including Cox multivariate analysis to determine prognostic factors.
Main Results:
- Squamous cell carcinoma was the most frequent type (56.2%).
- The mandible was the most commonly affected site (82.5%).
- Smoking history and advanced age (≥60 years) were independent predictors of poor overall survival.
Conclusions:
- Primary jaw malignancies predominantly affect the mandible, males, and middle-aged individuals.
- Radical surgical resection is fundamental for a favorable prognosis.
- Patients with a smoking history and advanced age face a higher risk of adverse outcomes.

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
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...
