Five patients had pleural plaques, 2 had diffuse pleural thickening (DPT), 1 had asbestosis, and 1 had round atelectasis. The pleural biopsy specimens showed a benign fibrotic pleura in all case. The symptoms and pleural pulmonary radiologic findings remained stable during the follow-up. BAPE is diagnosed by exclusion. A suspected diagnosis of BAPE with an asbestos exposure should be considered, especially with the presence of pleural plaques, and/or DPT, and rounded atelectasis. The MDT-based diagnostic approach may reduce misdiagnosis. BAPE is diagnosed by exclusion.

Timely access to treatment of lung cancer is dependent on efficient and appropriate patient assessment and early referral for diagnostic workup. This study assesses the impact of Cancer Care Ontario (CCO) Lung Cancer Diagnostic Pathway Guideline (LCDPG) concordance on access to treatment of stage IV lung cancer patients referred to the Diagnostic Assessment Program (DAP) at a Canadian tertiary cancer centre. This retrospective cohort study includes patients diagnosed with clinical stage IV lung cancer referred to the DAP at a Canadian tertiary cancer centre between November 1, 2015 and May 31, 2017. Referral concordance was determined based on CCO LCDPG. The primary outcome; time to treatment from initial healthcare presentation; was compared between the concordant and discordant referrals. Two hundred patients were referred for clinical stage IV lung cancer during the study period. Of these referrals, 151 (75.5%) were assessed and referred in concordance with LCDPG. Guideline concordant referrals were associated with reduced time to treatment from
