This document summarizes key points about precision medicine in stage IV lung adenocarcinoma as an example:
- Biomarker testing like EGFR, ALK, ROS1 is essential to select appropriate targeted therapies and has become standard practice, with 92% of non-squamous cases tested for EGFR and 79% for ALK.
- Ongoing clinical trials are exploring new targets like RET fusions, NTRK fusions, and KRAS G12C mutations and corresponding therapies.
- Next-generation sequencing allows comprehensive genomic profiling but challenges include methodology, turnaround time, and reporting of clinically relevant alterations.
- Liquid biopsies show promise for resistance mechanisms but have

• Emerging approach for disease treatment and prevention that takes into
account individual variability in genes, the environment, and lifestyle for each
person
üThe Cancer Genome Atlas, which helped define genomic changes that are
unique to different cancers
üPrecision medicine is providing “the right drug for the right patient at the
right time”

Biomarker Method Use LoE, GoR
EGFR mutation
Any appropriate, validated method, subject to external quality
assurance
To select those patients with EGFR-sensitizing mutations
most likely to respond to EGFR TKI therapy
I, A
ALK rearrangement
Any appropriate, validated method, subject to external quality
assurance. FISH is the historical standard but IHC is now
becoming the primary therapy-determining test, provided the
method is validated against FISH or some other orthogonal
test approach. NGS is an emerging technology
To select those patients with ALK gene rearrangements
most likely to respond to ALK TKI therapy
I, A
ROS1 rearrangement
FISH is the trial-validated standard. IHC may be used to select
patients for confirmatory FISH testing but currently lacks
specificity. NGS is an emerging technology. External quality
assurance is essential
To select those patients with ROS1 gene rearrangements
most likely to respond to ROS1 TKI therapy
II, A
BRAF mutation
Any appropriate, validated method, subject to external quality
assurance
To select those patients with BRAF-V600-sensitizing
mutations most likely to respond to BRAF inhibitor, with or
without MEK inhibitor therapy
II, A
PD-L1 expression
IHC to identify PD-L1 expression at the appropriate level and
on the appropriate cell population(s) as determined by the
intended drug and line therapy. Only specific trial assays are
validated, internal and external quality assurance are
essential
To enrich for those patients more likely to benefit from
anti-PD-1 or anti-PD-L1 therapy. For pembrolizumab,
testing is a companion diagnostic for nivolumab and
atezolizumab, testing is complementary

15. NGS en la práctica clínica
• Diferentes metodologías
üSensibilidad y especificidad del método escogido
(sobre todo para fusiones)
• Se deben incluir los marcadores relevantes
para la práctica clínica
• Material necesario para determinación
• Turnaround times
üDepende del número de test que se hagan
üImportante para no duplicar determinaciones
• Evaluación de resultados y control de calidad
16. Determinaciones moleculares en biopsia liquida
• Standard en algunas situaciones clínicas
üNecesidad de re-biopsia por material
escaso
üDeterminación de mecanismos de
resistencia
• Varias tecnologías, distintas
sensibilidades y especificidades
• Incluso mayores retos que con los
marcadores en tumor, dificultades claras
en el acceso
• Gold standard en el futuro próximo
18. The NGS era
• A highly competitive field!
Available at companies’ websites
19. Medicina de precisión, implementación
• Three goals that need to be achieved for precision medicine to be made widely available
üEducation
üInformation
üAccess
• Physicians need to learn how to interpret and treat different genomic changes
• Electronic health records must support the rapid and meaningful dissemination of
information to providers at the point of care
• Genetic testing and counseling need to be covered by payers, so people with cancer have
access to the necessary treatments
20. Precision oncology and its potential to widen disparities
• Molecular information leads to clinical trials
üThe RET example, 2 randomized trials in 1L, local testing
• Payers and funding agencies have important and multifaceted roles in precision medicine
21. • Registro tumores torácicos, estudio observacional,
multicéntrico en España
• 7.872 pacientes, 58 centros (agosto 16-diciembre 18)
• 3.446 pacientes (52.2%) tenían un E-IV en el diagnóstico
• En pacientes con histología no escamosa y E-IV, EGFR y
ALK se realizó en 92% y 79% respectivamente
• Hace tan solo 2 años la determinación de ALK se realizaba
solamente en el 40% de los pacientes
• La determinación de ROS1 se realizó en el 20% de los
casos

24. Development of an Amplicon-seq panel for VHIO prescreening
We amplify 350 regions (800 amplicons) in 61 genes frequently mutated in cancer with a matched
approved/ in clinical trials targeted therapy (oncogenes and tumor supressors):
The panel is especially suited for FFPE
derived DNA and cfDNA.
There is flexibility, new genes or
regions may be included in the panel.
Mutation detection is 5-fold
compared to Sequenom panels.

• Genomic testing: a true therapeutic revolution
ü If you don´t look for genetic alterations…forget the concept of precision
medicine
ü Tumor tissue availability
ü Role of liquid biopsy…the immediate present/future
• Drug access, clinical trials
• Education, collaboration, organization, validation, equity, evaluation…
