Abstract
Guidelines for optimal timing of lung cancer diagnosis and treatment have been implemented in many countries, but the effect of fast-track interventions on the shortening of time interval is still debatable. In this study, the delay from the first specialist visit to the histopathologic diagnosis was compared between two patient cohorts: before (n ¼ 280) and after (n ¼ 247) implementation of a fast-track multidisciplinary diagnosis program. The cumulative incidence function curves were compared, and hazard ratio was adjusted in the Cox model. The implementation allowed a statistically significant increase in the cumulative incidence of the lung cancer histopathologic diagnosis over time. Adjusted hazard ratio for patients accrued in the post-implementation cohort was 1.22 (1.03–1.45) (p ¼ 0.023), corresponding to a reduction of this waiting period by 18%. In conclusion, a multidisciplinary approach of the diagnostic process implemented at the initial visit allows a significant reduction of the timeline until the histopathologic diagnosis of lung cancer.
