1. ¿Podemos demorar el inicio de la QT de 1º línea?

2. ¿Podemos hacer QT personalizada?

3. ¿Podemos optimizar el tratamiento de los pacientes ancianos?

4. ¿Podemos mejorar los resultados de la QT de 1º línea con nuevos tratamientos?

5. ¿Algún esquema es más eficaz de los que disponemos?

¿Podemos demorar el inicio de la QT de 1º línea?

¿Podemos esperar a iniciar un tratamiento de 1º línea en CPNM?

- A “watch and wait” approach (WW) is commonly used in clinical practice:

- Asymptomatic patients with clinical features of indolent behavior

- palliation of symptoms is achievable with radiotherapy. - Whether this approach would have any effect on survival

outcomes has not previously been evaluated

Conclusions:

•25% of patients initial WW strategy.

•50% of patients in WW strategy never received CT

• Patients in WW strategy who received CT similar OS than upfront CT.

• patients in WW strategy that did not received CT inferior OS

Comentarios:

-La mayoría de los pacientes precisan QT inmediata, WW strategy es la excepción.

-El único beneficio de la WW strategy es retrasar la QT

-Podemos perder pacientes candidatos a recibir QT peor supervivencia

¿Podemos hacer QT personalizada?

• Two ERCC1-directed randomized trials (Cobo et al. JCO 2007; Bepler et al.

JCO 2013)

– no survival benefit for ERCC1-directed treatment over non-selected chemotherapy.

• SLCG phase II customized chemotherapy trial (Rosell et al. PLoS ONE

– BRCA1 and RAP80 expression had a combinatory effect on outcome in NSCLC patients.

Conclusions

• Prespecified interim analysis showed a detrimental effect in the experimental arm.

Trial prematurely closed

• Significant interaction between PS and treatment arm. Favorable effect for the

experimental arm among patients with PS 0

• We are now examining alternative biomarkers that could elucidate DNA repair

mechanisms.

Phase III, randomized, multicenter study comparing in elderly patients (≥70 years) with stage IV NSCL a standard strategy of treatment allocation (carboplatin based bi-therapy or monotherapy with docetaxel) based on PS and age with an experimental strategy allocating the same regimen or BSC according to a comprehensive geriatric assessment

OVERAL SURVIVAL (ITT)

Conclusions • First phase III customized trial evaluating the impact of a GERIATRIC ASSESSMENT

on decision making and treatments allocation.

• ESOGIA did not show a superiority of its CGA based strategy of treatment allocation in terms of TFFS

• In experimental arm: - 21% of frail patients exclusive BSC management - Significantly less treatment failures for toxicities. • Results of the QoL and survival adjusted on QoL are still pending

• Carboplatin-based doublets according to histology are feasible with a good

tolerance profile consistent with previous studies in selected elderly patients.

S124: Efficacy and Safety of Maintenance Pemetrexed in Patients with Advanced Nonsquamous Non-small Cell Lung Cancer (NSCLC) after

Completing at Least 4 Cycles of Pemetrexed plus Cisplatin Induction Treatment: a Cross-trial Analysis of Two Phase III Trials

G. Scagliotti, et al.

•Paramount: 4 cycles of induction treatment •Clinical practice /guidelines: 2 additional cycles •¿ 2 more cycles could accomplish the same outcome as the maintenance therapy?.

• Two arms of PARAMOUNT

•maintenance (N=359)

• placebo (N=180), 4 cycles without PD

• Homogeneous population from JMDB :

•346 patients with nonsquamous NSCLC

• ECOG 0 -1

• completed at least 4 cycles of pem+cis without PD.

• Patients enrolled in Korea and Taiwan were excluded

CONCLUSIONS • The PARAMOUNT placebo arm showed results consistent with the JMDB homogeneous group

treated with pemetrexed-cisplatin.

• The addition of pemetrexed continuation maintenance after 4 cycles of pemetrexed-cisplatin first-line treatment results in a statistically significant increase in OS and PFS compared with 2 additional cycles of pemetrexed-cisplatin treatment.

• Although there was an increase in the incidence of grade 3–5 toxicities with longer exposure to pemetrexed-cisplatin or maintenance pemetrexed, the overall incidence remains low, underscoring the relative safety of these treatment regimens.

Conclusions: -The PARAMOUNT placebo arm showed results consistent with the JMDB group. -Pemetrexed maintenance after 4 cycles of CP results in a statistically significant increase in OS and PFS vs 2 additional cycles of CP treatment.

Comentarios:

•Pem > Gefitinib en 2º línea CPNM WT

•Importancia de un biomarcador en la selección de tto, incluso 2º linea

•Cambio en nuestra práctica?

• Determinación EGFR

• Dudoso EGFR-TKI

Conclusiones:

-Ganetespib + Docetaxel mejora SG y SLP vs Docetaxrl en pacientes Dx >6m y LDH elevada

-No beneficio en OS en mKRAS.

¿qué podemos incorporar en

nuestra práctica? • El único beneficio de la WW strategy es retrasar la QT. Podemos perder pacientes

candidatos a recibir QT peor supervivencia.

• Ningún biomarcador para QT personalizada.

• Valoración subjetiva en la decisión de tratamiento en ancianos

– edad no es un criterio para ecidir el tto por si solo.

– ECOG !!

– COMORBILIDADES

– Instrumento objetivo

• Pemetrexed en primera línea :

– CIS-PEM 4 ciclos = 6 ciclos

– Pem mantenimiento tras 4 CP > 6 CP

• Pem > Gefitinib en 2º línea CPNM WT
