P15 Lung cancer multidisciplinary meeting – does the presence of emphysema on ct imaging correlate with obstructive spirometry or transfer factor?

Introduction and Objectives Spirometry is routinely performed prior to the lung cancer multidisciplinary meeting (MDM). However, smoking related lung disease in the setting of normal spirometry is thought to be relatively prevalent.1 We sought to evaluate if there was any correlation between common variables used in the assessment of patient fitness. Methods We performed a retrospective chart review of all patients discussed at the MDM from 1/1/2018 – 4/11/2019 who had a transfer factor (TLCO) Results Of the 104 patients who had a TLCO measured, 70 (67%) had obstructive spirometry (FEV1/FVC A TLCO When considering the MDM decision regarding treatment with curative intent versus best supportive palliative care, no individual variable was found to be significant (obstructive vs non-obstructive spirometry, p = 0.22; TLCO Conclusion We suggest that TLCO Reference Lowe KE, Regan EA, Anzueto A, et al.
