• Similar HR compared with the adjuvant approach, with an absolute 5-year OS improvement of 5%, for all stages: Stage I, 50% to 55%, Stage II, 30% to 35%, Stage III, 20% to 25%

• More conclusive evidence in favour Adjuvant CT

• Key results (cont.)

- Strong PD-L1 tumour expression correlated with improved response, PFS and OS

Conclusions- Pembrolizumab was effective in patients with treatment-naïve or previously treated

advanced NSCLC- In particular, patients with strong PD-L1 tumour expression may benefit from this

treatment

LBA43: Antitumor activity of pembrolizumab (MK-3475) and correlation with programmed death ligand 1 (PD-L1) expression in a p ooled analysis of patients (pts) with advanced non-small cell lung carcinoma ( NSCLC) – Garon E et al

Strong PD-L1 positivity defined as staining in ≥50% of tumour cells, and weak PD-L1 positivity as staining in 1–49% of tumour cells. Negative staining is no PD-L1 staining in tumour cells. Data cutoff: March 3, 2014.

– Patient characteristics were balanced between the two groups (~70% were <65 years of age; 73% male; ~50% had adenocarcinoma; ~25% were never smokers; ~95% had received prior platinum-based therapy)

¿Qué hemos aprendido en 2014?

• Adyuvancia: – Erlotinib no mejora la SLP en p. EGFR + por FISH o IHQ.

– EGFR-TKI en p. mutación EGFR + ¿?

• Localmente avanzado: – QT neoadyuvante a Cirugía mejora un 5% la SG a 5 años.

• Mutación de EGFR:– Afatinib mejora la OS frente a QT (pooled analysis)

– Erlotinib + Bevacizumab mejoran PFS vs Erlotinib

– Deleción exon 19 mejores resultados

– Resistencia adquirida (T790M +): EGFR-TKI 3ª generación (AZD9291,

CO-1686) son eficaces.

– Tras PR a Gefitinib, continuar con Gefitinib + QT no mejora SG vs QT

– Criterios RECIST pueden no ser útiles, EGFR-TKI pueden aportar

beneficio en PR clinicamente no agresiva

¿Qué hemos aprendido en 2014?

• Translocación de ALK:– Crizotinib mejor SLP y RR que QT en 1ª línea

– Ceritinib eficaz en pacientes previamente tratados y sin tratamiento

previo, y activo en pacientes con M1 SNC (también Crizotinib)

– Alectinib activo en p. pretratados, tb con afectación SNC

• Traslocación ROS1:– Crizotinib es activo

• Amplificación de MET:– Historia de tabaquismo

– Crizotinib eficaz en p. con amplificación MET por FISH

• Inmunoterapia:– Inh PD1/PL1: Activos en CPNM avanzado pretratados y 1ª línea

– Mayor actividad en PD-L1 +

– Por definir el mejor método para determinar PD-L1, cómo evaluar la

eficacia,…

¿Qué hemos aprendido en 2014?

• Nuevos Fármacos:– Necitumumab mejora SG y SLP en 1ª línea

– Nintedanib mejora SLP y SG en adenocarcinomas en 2ª línea

– Ramucirumab mejora SG y SLP en 2ª línea

– Afatinib en ca escamoso en 2ª línea mejora SLP respecto de Erlotinib
