Conclusions
• MET exon 14 alterations should now be assessed routinely in advanced NSCLC – Next generation sequencing assays are adequate
• Presence of MET exon 14 alterations predicts for response to MET inhibitors
• Recommended algorithm for MET exon 14 altered NSCLC:– Refer for clinical trial consideration– In absence of clinical trial, crizotinib is appropriate

Patterns of Failure
• Difference in patterns of failure trended towards significance (p=0.09)– Higher proportion of locoregional only failures in no-LCT
arm (17% in no-LCT vs. 4% in LCT arm)– Higher proportion of metastatic only failures in LCT arm
(40% in LCT vs. 25% in no-LCT arm)– Higher proportion of both locoregional and metastatic
failures in no-LCT arm (29% in no-LCT vs. 8% in LCT arm)

Conclusions
• In oligometastatic (1-3 mets) NSCLC, local consolidative therapy after systemic therapy appears to improve PFS– Exploratory analysis: LCT increased time to development of new
lesions• Results of trial are intriguing but not yet practice
changing– Population: highly heterogeneous (clinically and
biologically)– Sample size: limited– Quality of life: unknown– Crossover design confounds overall survival endpoint

Conclusions
• Alectinib is superior to crizotinib as frontline therapy of ALK-positive NSCLC– RR: 85% vs 70%– PFS HR = 0.34 (p<0.001)
• mPFS: Not reached vs. 10 months– Time to progression for those with brain metastases: PFS was 92%
better for alectinib– Toxicity profile favored alectinib
• Caveats: Japanese-only trial, cost (third party reimbursement) • Bottom line:
– Alectinib can be considered as frontline ALK-targeted therapy (particularly pts with brain mets)
– We await definitive results of global ALEX trial

Hypothesis
Proton therapy will – Reduce irradiated lung volume, hence
reduce radiation pneumonitis (RP)– Achieve same local control (LC) with
same biological effective radiation dose (Proton relative biological equivalence=1.1)

Primary Objective
Protocol Failure (Dual endpoints):• Radiation Pneumonitis grade > 3

• Local failure (PET, CT, biopsy):– IMRT = 3DPT– 15% at 6mo & 25% at 12mo.

Conclusions
• Proton beam RT is no better than standard IMRT– Primary endpoint not met
• Pneumonitis numerically worse with protons• No significant differences in treatment failure rates• Trend for worse survival with proton beam
– IMRT 29.5 months vs. Proton 26.1 months
• Results dispel prevailing notion that proton beam RT is superior to standard RT
• Lack of clear benefits of proton beam RT do not justify its higher cost in this patient context
