The length of patient and primary care time interval in the pathways to treatment in symptomatic oral cancer. A quantitative systematic review.

Patient interval represents the major component of waiting times since the detection of the first signs/symptoms to the definitive diagnosis of oral cancer. Thus, strategies focused on high-risk patients should be prioritised. Interventions aimed at optimising the health systems should be implemented by monitoring and facilitating diagnostic and treatment pathways of patients with oral cancer.
