Stage IV bile duct cancer
Stage IV bile duct cancer is divided into two subcategories:
- Stage IVA: The cancer is growing and has spread to the main blood vessel and the lymph nodes but not to distant sites (Example grouping: T4, N1, M0).
- Stage IVB: The cancer has either spread to lymph nodes away from the tumor (N2) or it has spread to distant sites (M1) (Example grouping: any T, N2, M0; any T, any N, M1).
