CRT: role of consolidation CT after CRT?
45 trials, 9 phase III, 36 phase II with 51 arms
No difference between the two groups,
med OS: CT 18.5 mo vs no CT 18.1 mo

CRT: role of hyperfractionation

Operable stage IIIA:
Adjuvant Chemotherapy: OS better!

Operable Stage IIIA
Does adjuvant RT help? NO!

JNCI, 2007
•Unresectable (?) N2
•With response to Induction
3 x Cis/Carbo + X
•OP vs. RT (60 Gy)
•1. EP: OS
•50% complete resection!
•41% downstaging to ≤ypN1

Lancet 2009
 Resectable N2
 Induction CRT:
3x Cis/Eto + RT 45 Gy
 If no PD:
RT to 61Gy vs. OP
 1. EP: OS

Stage III
• Very heterogeneous disease
• <30% can be cured (70-80% are NOT!)
• Both local and distant relapse are a problem!
• Requires bimodal treatment
• always Chemotherapy: minor effect
• Surgery vs. Radiotherapy?
• Trimodal treatment?

(Cis-)Platinum based, concurrent
type and dose
Which Radiotherapy?
>60 Gy, less than 70 Gy
type, dose, fraction
Which combination?
Surgery + Chemotherapy
Stage IIIA/N2
Radiotherapy + Chemotherapy
Stage IIIB/IIIA?
