Lung Dose Contraints and PFT's

For those treating lung cancer, how do use PFT's to alter your contraints for a conventionally fractionated case or do you. I have a non surgical candidate with DLCO of 35% (T2N1M0) on 2L of O2 will be treated concurrent chemoRT. Do you use different constraints depending on how poor lung function patients have. Thank you

Not really, I think it is more to establish a baseline function and meet ACR accreditation requirements 🙂

In early-stage they are often seeing you because they have such poor PFTs in the first place

Agree, and for these patients there's not much of an alternative since it's still lung cancer.

alos, lung DVH constraints are work in progress given weird RTOG 0617 data

In my mind PFTs are essentially to rule surgery in/out. I do not modify V20, V5, or mean lung dose constraints based on underlying pulmonary pathology.
