19
Q

What are characteristics of large cell?

A
  • Agressive, rapid

- Peripheral w/ prominent necrosis (but can be central)

20
Q

What are characteristics of small cell?

A
  • Bronchial origin
  • Begin centrally, infiltrate submucosally –> narrowing of bronchus
  • Aggressive, poor px
  • Distant metastasis at time of dx
21
