Abstract
Background: Lung cancer remains a global public health challenge, with late-stage diagnosis limiting treatment options. Surgery is recommended for early-stage disease (I-IIIA) and can only be performed in authorized centres. The aim of this study is to provide a spatial description of access to surgery for lung cancer patients and to identify the sociodemographic characteristics of patients who are furthest from home for their treatment.
Methods: A population-based study was conducted on patients diagnosed with non-small cell lung cancer (stages I-IIIA) between 2008 and 2020, identified from the Poitou-Charentes Cancer Registry (south-western France). The distance between the patient's home and the place of surgery was computed using geographic coordinates. A map of patient flows by department was produced. Logistic regression models were used to identify sociodemographic and tumour factors associated with distance to surgery (cut-off 100km). Sensitivity analyses were performed by varying the distance threshold (50, 150 and 200km).
Results: Twenty-two percent of patients travelled more than 100km for surgery. This proportion was higher in Charente and Charente-Maritime (45% and 31% respectively) than in Deux-Sèvres and Vienne (9% and 2% respectively). Female sex and middle socioeconomic status were associated with a greater distance travelled for surgery. Sex was the only variable that remained significant for all thresholds studied.
Conclusions: Sociodemographic factors including sex, place of residence and socioeconomic status are important determinants of distance travelled for lung cancer surgery. These findings allow better understanding of these patients' pathways taking into account regional specificities.
