LACE – Benefit by Stage
CT may be detrimental for stage IA, but stage IA patients were generally not given cisplatin+vinorelbine (13% of stage IA patients versus ~43% for other stages)

• Between Aug 2007 and Jan 2010, 557 patients were enrolled:– median age 61– 52% female– 54% adeno, 31% squamous – 23% IB, 43% II, 29% IIIA (N2) , 4% IIIA (T3N1)
• Adjuvant regimens:– 28% C-V– 34% C-D– 26% C-G – 12% C-P (added later)
• Overall Gr 3/4 toxicities are increased in Bev arm; Gr 5 toxicity was 2.5% vs. 3.8% without or with Bev

Inclusion:Inclusion:• NSCLC stages IB, IIA, IIB, T3N1M0• ≤ 42 Tage postoperatively, R0, systematic LN-dissection• ECOG 0, 1 - amenable to cisplatin treatment
Rationale:Rationale:• Need: reduction of toxicity, improvement of dose delivery & compliance
• Cisplatin / pemetrexed in thoracic malignancies: high dose intensity, low toxicities

Adjuvant Therapy of NSCLC
• Stage IB
• Chemotherapy choices– Use cisplatin whenever possible– Cis-Vnb is associated with greater toxicity

There is benefit of PORT in stage IIIA-N2 disease, and the role of PORT
in early stages of NSCLC should be clarified in ongoing phase III trials.

• Stage IB
• Chemotherapy choices
• PORT– No benefit in N0 and N1 disease– Consider in N2 patients – especially with multi-station
involvement and/or extra-capsular spread– Do it sequentially
