Guidelines recommend rapid evaluation of patients with suspected lung cancer, but the impact on survival remains unclear. We reviewed medical records of all patients with newly diagnosed lung cancer in four hospital networks across the province of Quebec, Canada, between 1 February and 30 April 2017. Patients were followed for 3 years. Wait times for diagnosis and treatment were collected, and survival analysis using a Cox regression model was conducted. We included 1309 patients, of whom 39% had stage IV non-small cell lung cancer (NSCLC). Median wait times were, in general, significantly shorter in patients with stage III\u2013IV NSCLC or SCLC. Surgery was associated with delays compared to other types of treatments. Median survival was 12.9 (11.1\u201315.7) months. The multivariate survival model included age, female sex, performance status, histology and stage, treatment, and the time interval between diagnosis and treatment. Longer wait times had a slightly protective to neutral effect on survival, but this was not significant in the stage I\u2013II NSCLC subgroup. Wait times for the diagnosis and treatment of lung cancer were generally within targets. The shorter wait times observed for advanced NSCLC and SCLC might indicate a tendency for clinicians to act quicker on sicker patients. This study did not demonstrate the detrimental effect of longer wait times on survival.<\/jats:p>","DOI":"10.3390\/curroncol29050259","type":"journal-article","created":{"date-parts":[[2022,4,29]],"date-time":"2022-04-29T16:49:57Z","timestamp":1651250997000},"page":"3187-3199","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Wait Times and Survival in Lung Cancer Patients across the Province of Quebec, Canada"],"prefix":"10.3390","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8210-6364","authenticated-orcid":false,"given":"Marie-H\u00e9l\u00e8ne","family":"Denault","sequence":"first","affiliation":[{"name":"Centre de Recherche de l\u2019Institut Universitaire de Cardiologie et de Pneumologie de Qu\u00e9bec, 2725 Ch.
