Multiple Primary Tumours in Oral Cancer: Patient Characteristics and Survival Patterns.

The development of MPTs significantly affects the survival of oral cancer patients. Advanced age, comorbidities and delayed initiation of treatment were identified as key risk factors for MPTs. The poor survival outcomes, particularly in patients with synchronous tumours, advanced-stage primary cancers and specific comorbid conditions, highlight the need for early detection and proactive management strategies to mitigate these risks and improve long-term survival in this population.
