A topic that came up in a recent expert round table case discussion was the issue of how to manage a patient with a lung cancer for which the pathology report says "NSCLC not otherwise specified (NOS)", or "poorly differentiated NSCLC, NOS". What does this actually mean, and what does it mean in terms of treatment options?
Here's a webinar case discussion I did with Drs. Julie Brahmer from Johns Hopkins in Baltimore, and Greg Riely from Memorial Sloan Kettering Cancer Center in New York. They're great thoracic oncologists as wellas friends, and they were kind enough to join me for discussion of several complex cases that don't have clear answers and illustrate the reality that even when we know the evidence, there's plenty of room for judgment.
