This is the first part of a case presentation I did with two great colleagues: Dr. Anne Tsao, who is a medical oncologist and lung cancer expert at MD Anderson Cancer Center in Houston, and Dr. Alex Farivar, who is a terrific thoracic surgeon at my own institution, Swedish Cancer Institute in Seattle.

This case is an elderly gentleman who has a very indolent but growing lung lesion. His story brings up questions of how concerned to be in following a nodule in a patient of advanced age and with competing medical issues, whether surgery that is less than a lobectomy might be considered, as well as the systemic therapy options for bronchioloalveolar carcinoma.

I hope that's helpful. We'll provide info on a couple of additional cases from this discussion in the future.
