Objective:
To measure the primary care interval (PCI) in the diagnostic delay of oral cancer and to assess the relation of the referring physician's specialty with disease stage at diagnosis.
Methods:
We meta-analyzed reports of oral/oropharyngeal carcinomas detailing PCI start- and endpoints, i.e., the time needed by a primary care physician to refer a suspected oral cancer patient to a specialist.
Results:
17 studies with a total of 2530 patients were eligible; nine provided data on the relative length of PCI, and 10 reported on the impact of the referring professional's specialty on oral cancer diagnostic delay. The average PCI length was slightly longer for general practitioners (GPs) (30.5 days) than for general dental practitioners (GDPs) (27.6 days), while that for the total group was 28.7 days. One-third of the total pre-hospital time spent on diagnosis elapses in GP practices (PCI%: 0.31 [95% CI: 0.23, 0.40]). GDPs refer their patients for treatment at earlier disease stages (TNM I-II) than GPs (Odds Ratio: 0.58; 95% CI: 0.34-0.98).
Conclusions:
Primary care accounts for a considerable pre-hospital amount of time of what is necessary for reaching a diagnosis of oral cancer patients. This calls for enhancing early oral cancer recognition in primary care settings.
