17. Chemotherapy Today and the
Need for Targeted Therapies
Doublet chemotherapy for 4-6 cycles is standard
Can now select chemotherapy based on histology
Future selection by other markers (ie, ERCC1)
There is a need for “targeted” chemotherapy and
other agents
Antiangiogenesis: VEGF targeted (bevacizumab, etc)
EGFR-targeted antibody (cetuximab), TKI (erlotinib,
etc)
Newer targets (ALK and others)
Recent identification of “driver mutations” in 50% of
NSCLC adenocarcinomas

22. Bevacizumab in Special
Populations: Summary
Caution with elderly patients; ongoing trials
Hemoptysis remains an issue, but
anticoagulation can be considered cautiously
Safe in patients with treated brain metastases
Squamous histology still a major bleeding risk
23. EGFR and NSCLC
EGF binds to the EGFR
to regulate cell growth, proliferation, and differentiation
Erlotinib and gefitinib are inhibitors of the TK enzyme in the
EGFR
Cetuximab is a monoclonal human-murine chimeric antibody
against EGFR with some NSCLC activity

37. Summary: First-line NSCLC
Therapy
Doublet chemotherapy still standard backbone
regimen
Some selection possible; histology
Targeted drugs can add to doublet chemotherapy
Bevacizumab and cetuximab with survival benefit
MANY with NO benefit in unselected patients in this
setting
EGFR-TKIs, VEGFR-TKIs, MMPs, immunomodulators
Targeted agents where target is known can
replace first-line chemotherapy (EGFR-TKI in
EGFR mutants)
Better biomarkers will lead to better targeting
